Description

Optional automatic car

The present invention relates to a powered golf cart, and more particularly to a golf cart that is advanced, foldable, and has two selectable modes of operation.

One of the two selectable modes of operation is a driving mode in which the driver can stand on the vehicle while the golf cart is traveling in the course; the second of the two selectable modes of operation is a walking mode in which the golf is When the golf cart is in use, the user walks behind the vehicle, and the golf bag with the golf club accessories and other possible supporting equipment is provided with appropriate support by the bracket provided with the vehicle.

In a round of golf, many players need and expect to perform exercises provided by at least part of the route, but the players find that if they follow the 9-hole or 18-hole route of the game, the time will be as high as 5 Hours often cause a huge drain on physical strength, especially when encountering difficult terrain. If the golfer is walking through the pitch using a conventional motorized golf cart, the golf cart must be fully driven, resulting in a lack of desired walking exercise. From another point of view, if the golfer chooses to walk through the course, then whether they choose to carry a bag weighing 20 kilograms or choose to carry the bag to one of a wide variety of bag cars, Whether these carts are hand-push/pull or powered, golfers must walk all the way because they only carry the bag.

Therefore, it is necessary to provide a foldable switch that can be switched between walking mode and driving mode. A stacked golf cart, which should be able to be used as a stroller for walking while walking through certain holes, and as a rideable golf cart while walking through the remaining holes. Some solutions have been proposed in the published U.S. Patent Nos. 6,474,427, 5,346,028, 4,874,055, 4,848,504 and 4,538,695; British Patent Publication No. 2,242,404, and WO-2004/03K16-A1; and European Patent Office Patent Publication No. 0602300 A1.

Most of the existing solutions involve only changes in the tilt angle of the joystick, such as a pull-back walk mode in which the joystick is tilted forward, or a walking mode in which the joystick is tilted more in line with the demand. In order to overcome the difference in geometric position between the walking and driving modes, it is necessary to change the tilt angle of the joystick in a wide range, and the driver needs to perform a large manual operation, so that the tilt position of the joystick is difficult to manipulate. In addition, it is necessary to keep the wheelbase constant in the driving mode, but keeping the wheelbase constant in both modes makes it difficult to operate a golf cart with a long vehicle length in the walking mode. Only two of the above patents relate to changing the length of the wheelbase when switching between driving and walking modes.

The document of U.S. Patent No. 4,848,504 provides a detachable driving unit that can be separated from the connection point on the drive unit and connected to a higher point on the joystick for cleaning the drive unit and following the walk behind The space between the users. However, the solution of this document requires good coordination of the user, because the drive unit has only two wheels, and it is necessary to lift the bracket under the golf bag off the ground while manipulating the golf cart during driving.

The document of U.S. Patent No. 6,474,427 discloses a wheelbase extendable motorized golf cart having a steering member mounted on the front wheel assembly of the golf cart, the steering member being rotated from the rear when the pedestrian mode and the driving mode are selected for switching Move forward to increase the wheelbase of the golf cart. The drawback of this solution, however, is its complexity, which requires a mechanical device that includes a sliding arm and meshing gears. In addition, the user must take special actions when making mode selections.

The main object of the present invention is to provide a battery-powered, foldable golf cart with a walking/driving dual operating mode that has the same handling performance in both modes and can be conveniently selected according to The operating mode sets the selectable wheelbase.

Another object of the present invention is to provide a battery-driven golf cart with a walking/driving dual mode comprising three units: a push/ride unit, a golf bag carrying unit, and a front wheel unit. The three units are interconnected by a linkage system in a dual mode of operation for linkage, the linkage system having two stable positions.

It is still another object of the present invention to provide a battery-powered golf cart with a walking/driving dual mode comprising two units: a push/ride unit and a joystick unit. The two units are interconnected by a linkage system in the dual mode of operation for linkage, the linkage system having two stable positions.

In a preferred embodiment of the present invention, the pushing/riding unit further includes a pair of side-mounted, left-right driving devices, and the driving device is driven by an electronic differential The power supply can provide more power for one side of the drive unit and less power for the other side of the drive unit according to driving requirements.

In a second embodiment of the present invention, a battery-driven golf cart with a walking/driving dual mode is provided, comprising two units: a push/ride unit and a joystick device unit. The two units are interconnected by the linkage system into an organic unit in the dual mode of operation, the linkage system having two stable positions.

Further, in the second embodiment described above, the joystick device includes a steering handle connected to a pair of steering wheels.

The structure of the foldable, walking/driving dual-mode golf cart of the present invention, as shown in the first and second figures, includes three basic units, namely: an implementation/riding unit A, a golf bag carrying Unit B and a front wheel unit C. The three units are interconnected by a linkage system to effect linkage in two modes with two stable positions. The linkage system D includes a linkage, a spring or brake, a pivot pin or pivot bolt, and a brake device.

The specific structure of the implementation/riding unit A is shown in the third figure, including a walking/driving unit E and a joystick device F. The E and F units are connected by a quick release locking device K. The walking/driving unit E further includes a pair of side-mounted driving devices R and L which are mounted on both sides of the rear portion of the frame 12 and which are divided into left and right. A battery/electronics compartment 14 (shown in the fourth figure) includes two batteries and control circuits that are bridged by a handle 16 and is detachably placed at the front end of the frame 12 (as shown in Figure 7). The matching bases 18 and 20 are shown and an intermediate position is reserved for the locking device K. A foot pedal 24, made of a perforated non-slip material, is located in a hollow region between the drive units R and L of the frame 12. The drive units R and L further include a high speed worm gear reducer 28 driven by a motor 30 and a drive wheel 26 coupled to the high speed worm gear reducer 28. The drive wheels 26 of the drive units R, L are respectively connected to the corresponding sides of the gears 28, and similar standard components are used on both sides of the R and L.

As shown in the fifth figure, the structure of the joystick device F further includes a tubular support body 34 and a slanted reinforcing portion 36 welded or firmly connected to one end of the tubular support body 34. The other end of the tubular support body 34 passes through the locking device K. Removably attached to the frame 12. One or two side walls have U-shaped brackets 42 with two through holes reserved for the pivot pin or pivot bolts 44, 46 (as shown in the ninth and tenth views), while the U-shaped bracket 42 is welded or passed. Other means are fixed to the front end of the tubular support body 34 and keep its opening forward. A brake lever 48 has a forked structure 50 at one end that projects forwardly from the upper end of the bracket 42 as a brake in the walking mode. A short U-shaped bracket 52 having a through hole in one side wall is fixed to the bottom of the support portion 34 by welding or other means, and the short U-shaped bracket 52 is opened downward, and the through hole is reserved for the pivot pin or the pivot bolt 54 (such as Nine and tenth figures).

As shown in the fifth and sixth figures, the joystick device F further includes a telescoping tube 58 that is clamped by the tubular member 56 and that facilitates sliding, and a handle 60 at the top thereof. An adjustable base 66 is located on the right side of the handle 60 near the armrest, and a battery-powered remote wireless controller 70 mounted on the adjustable base 66 is used to manipulate the golf ball. The journey of the car (described in more detail below). Both ends of the tubular member 56 are respectively provided with annular clamps 62 and 64 through which the height of the handle 60 can be adjusted, and the through hole of the upper annular clamp 62 is reserved for the pivot pin or the pivot bolt 68.

The handle 60 is not used as a driving lever and is only used to hold the hand in the driving mode to maintain balance. The driving function of the golf cart is implemented by the remote wireless controller 70 and a spherical joystick 72. When the spherical joystick 72 is tilted forward, the golf cart is advanced; for example, when the spherical joystick 72 is operated to tilt to the right, electrons are generated in the battery/electronics bin 14 (as shown in the fourth figure) The differential signal provides more power to the left drive unit L, and provides less power to the right drive unit R, and turns the drive vehicle to the right through the electronic pulse width modulation switch. The specific situation of this process will be as follows. For further details. The remote wireless controller 70 is secured to the sized base 66 by a locating clip 74 that the user can remove from the base 66 at any time (as shown in Figure 6). This design is used in walking mode, allowing the user to control the motion of the cart at a distance while walking behind the car.

To facilitate use, the remote wireless controller 70 has a sensor that can detect the motion of the driving device, and can reduce the speed of the vehicle before or during cornering, before or during rotation, or in other motions. Design can improve the safety and stability of the cart.

An optional direction detecting unit can be used with the battery/electronic instrument housing 14 to detect the relative position of the remote wireless controller 70 and the cart, thereby enabling the cart to Follow the user to travel. This specially designed optional mode frees the user from manual instructions for the action of the cart.

As shown in the seventh and eighth figures, the locking device K securely connects the walking/driving unit E with the joystick device F. The locking device K consists of a rectangular base 73 that is connected to the frame 12 between the battery compartment bases 18 and 20. The base 73 is shaped as a top open box with a recess in the lower portion of the inner front wall; the bottom of the reinforcing portion 36 is connected to the base 73 by inserting the slit 37 into the lower recess of the base 73, and the rotatable lock of the reinforcing portion 36 when locked The arm 75 is rotated into the groove 39, and then the rail 77 is pulled down to lock.

The second basic unit of the dual mode cart is the golf bag carrying unit B, the structure of which is referred to the fourth and ninth figures, further comprising: a curved member 76 (better shape of the round tube), the lower end bracket of the golf bag 78 and upper bracket 80. Below the lower end bracket 78 is provided a forward extending plate 82 for carrying the weight of the golf bag 84. The golf bag 84 is securely attached to the brackets 78 and 80 by, for example, an elastic band (not shown) that can be quickly disconnected. The curved member 76 has a through hole laterally located at a distance above the lower end bracket 78, the through hole being reserved for the pivot pin or pivot bolt 86. A U-shaped bracket 88 (not shown in the fourth and ninth drawings) is fixed to the curved member 76 by welding or other means, is located below the upper end bracket 80, and has a rearward opening, and the through holes are pivot pins on both side walls. Or bolt 90 is reserved. The golf bag carrying unit B, including the surface 82 and the brackets 78, 80, is pivotally coupled to the push/ride unit A by the linkage system D.

The third basic unit of the dual-mode golf cart is the front wheel unit C. For the structure, please refer to the third, fourth and ninth figures, including: a wheel 92 and a bearing connected to the vertical axis of the wheel 92. An upper plate (not shown) and a fixed plate 94 connected to the upper plate. A U-shaped bracket 96 is fixed to the upper side of the fixing plate 94 by welding or other means; the bracket opening is upward, and the side walls at both sides have through holes reserved for the pivot pin or the pivot bolts 102, 104. The two forming tubes 106 and 108 are respectively welded or otherwise fixed to the plate 94 and the U-shaped bracket 96, respectively, on both sides of the U-shaped bracket 96. And the top ends of the tubes 106 and 108 have transverse through holes reserved for pivot pins or pivot bolts 86.

The three units A, B and C described above are interconnected by the link system D, and linkage is realized in the two modes. The function of the linkage system D is to effectively connect the three basic units and select an operating mode, which in essence can be considered a "four-bar linkage system". One of the system applications is the connection of the golf bag carrier unit B to the push/ride unit A, and the second application is the connection of the front wheel unit C to the push/ride unit A. Each of the four-bar linkage system includes four shaft-connecting members that are connected by a four-point pivot pin or pivot bolt.

As shown in the ninth figure, for the front wheel unit C, the imaginary straight line between the pivot 102 and the pivot 86 is considered to be the first rod; the imaginary straight line between the pivot 54 and the pivot 46 of the pushing/riding unit A It is considered to be the second rod; as shown in the third figure, the pair of connecting rods 112 and 114 between the pivot 46 and the pivot 86 as a unit is considered to be the third rod; the pivot 54 and the pivot 102 The connecting rod 116 is considered to be the fourth rod. The spring unit 118 can be a pneumatic spring, an electronic brake or an electronic controller, etc. The shaft 104 and pivot 44 are coupled to the four-bar linkage system, but only control switching between the two modes and are not part of a four-bar linkage system. The relationship between the lengths of the rods in the four-bar linkage system allows for different angle changes of the rods while the shaft joints remain connected. The main advantages of the four-bar linkage system can be obtained by comparing the ninth and tenth diagrams. Although the push/ride unit A has undergone an angular change of up to 60° from the level position, the vertical axis of the front wheel unit C remains vertical. This feature of the invention ensures the driving efficiency of the golf cart in both modes. In both modes, the utilization of the electronic differential system and the accurate positioning of the wheel 92 ensure that the control of the vehicle is only by controlling the relative power supply to the drive units R and L. When the wheel 92 is accurately positioned, it will automatically adjust the required driving angle due to its structure.

When the pneumatic spring 118 is selected, the golf cart will remain in the walking mode under normal conditions, as shown in the fourth figure, with the curved member 76 placed on the fork structure 50 of the brake lever 48. When the user wishes to switch to the driving mode, simply stepping on the tilted pedal 24, the weight of the user will cause the pneumatic spring 118 to retract, and the push/ride unit A will slowly lower to switch to the driving mode. When an electronic controller is used in place of the pneumatic spring, an electronic switch can be mounted on the armrest 60 so that the user selects the mode to switch, and the switching vehicle will always maintain the current mode.

The golf bag carrying unit B is connected to the push/ride unit A in a similar manner with another set of four-bar linkage system. As shown in the ninth and tenth figures, in the carrying unit B, the imaginary straight line between the pivot 86 and the pivot 90 is regarded as the first rod; in the pushing/riding unit A, the pivot 46 and the pivot 68 The imaginary line between them is considered to be the second shot; As with a four-bar linkage system, a pair of connecting rods 112 and 114 between the upper pivot 46 and the pivot 86 are considered to be a third rod as a unit; and a connecting rod between the pivot 68 and the pivot 90 120 is considered the fourth shot. In this system, the length of the connecting rod 120 is very close to the connecting rods 112 and 114, and the distance between the pivot 86 and the pivot 90 is very close to the distance between the pivot 46 and the pivot 86. Therefore, when switching to the walking mode, the position of the golf bag carrying unit B will change as the angle of the pushing/riding unit A changes, and at the same tilt angle as the joystick F (as shown in the tenth figure).

In addition, as shown in the eleventh figure, the golf cart of the present invention can be quickly disassembled into three compact and lightweight parts. The disassembly step is: first remove the battery/electronics bin 14 and then lift the lever 77 to open the locking device K. As shown in the twelfth figure, the three sections can be placed in the trunk of the car for easy transportation.

Referring to the thirteenth to twenty-secondth drawings of the second embodiment of the present invention. Specifically, as shown in the thirteenth and sixteenth embodiments, the foldable dual-mode golf cart of the second embodiment of the present invention includes two basic units, a pushing/riding unit V and a joystick device S. The two units are interconnected by a linkage system that achieves linkage in two modes, the linkage system having two stable positions. The linkage system T includes a connecting rod, a pivot pin or a pivot bolt, and a brake device.

For the specific structure of the implementation/riding unit, please refer to the fifteenth and sixteenth drawings, including a pair of side-mounted, separate left-hand drive devices L and right-hand drive devices R, which are respectively located at the rear side of the frame 202. . One foot pedal 204, protected by perforation The slip material is manufactured in a hollow region between the drive units R and L of the frame 202. The shape of the aforementioned frame and foot pedal allows the user to stand on both feet at the same time while leaving a V-shaped portion 206 in the front center for folding the unit into the walking mode shown in Fig. 15. The structures of the driving devices R and L are similar. For details, please refer to the first embodiment of the present invention. A connecting member 208 with a four-hole bracket 210 is securely attached directly to the middle of the frame 202 by welding or otherwise, directly behind the open portion 206 as the first rod (rear) of the connection system T.

The joystick device S further includes a rotatable handrail bar 216 coupled to a pair of steering wheels 218, a battery/electronics bin 220, and a golf bag carrier 222. The battery/electronic instrument compartment 220 (shown in Figure 17) includes four batteries 224 and control circuitry 226 that are placed vertically in front of the joystick 228. The battery is coupled to the frame 230 and includes a front cover 232 and a rear cover 234 that are shaped to match the shape of the battery (shown in an open state in FIG. 17); the front cover 232 serves as an inclined seat for the golf bag 236 at the same time. Compared to the first embodiment, the grab bars 216 herein can control the cart and allow the user to control the cart in a manner similar to cycling.

The driving portion, as shown in FIG. 19, includes an axle 240, a frame 230 with the axle 240 as a bottom, a Pitman arm 242 at the bottom end of the lever 228, a fixing rod 246 and its rod end 248, and a steering arm. 251, a shaft 252, a joint 250 of the center rod 253, and two steering wheels 218. The armrest 216 is provided with a control switch 254 mounted on the top end of the operating lever 228, fixed and rotatable by the upper bearing 256 and the lower bearing 258, and conforming to the frame 230 in size. The length of the Pitman arm 242 and the steering arm 251 is off. The connection and the connection position between them are based on the Ackerman manipulation geometry (turning camber) familiar to those skilled in the automotive industry. A similar two-hole bracket 260 is fixed to the bottom of the shaft 240 by welding or other means, carries the fixing pin 262, and can be used together with the through hole 264 on both sides of the frame 230 to connect the operating device S with the link system T Two shots (front) 266 (as shown in Figure 19). The golf bag carrying device 222 is advanced from the center of the shaft 240.

The above two units V and S are interconnected by the link system T, and linkage is achieved in two modes. The basic elements of the connection system have been discussed in the first embodiment of the invention. The four rods are interconnected by a pivot pin or pivot bolts 263, 265, 267 and 269 (as shown in Fig. 19). The principle of operation is substantially the same as that described in the first embodiment, however, in this embodiment, no spring, pneumatic spring or brake is required, because the two modes are stabilized by controlling the balance of the weight of the joystick device and the battery compartment. The third rod (upper portion) 268 and the fourth rod (bottom) 270 and the brake extension portion 272 are axially coupled to the first rod (rear) 208 and the second rod (front portion) 266 of the linkage system T. The second rod 266 includes a bottomed grooved projection portion 274 and two extension portions 276. The second extension portion 276 has a pull-out release handle 278 for easy decomposition of the golf cart, as will be described in more detail below.

When the handrail is pulled back, the golf cart's mode will be shifted to the walking mode, at which point the brake extension 272 will stabilize at the top bar 268 (as shown in Figure 13). When the user wishes to switch to the driving mode, it is only necessary to step on the inclined foot pedal 204, and the weight of the user acts on the inclined foot pedal, so that the pushing/riding unit A is lowered. To switch to the driving mode, the brake extension 272 will now stabilize at the rear lever 208 (as shown in FIG. 14). Each mode will remain stable until it is manually switched to another mode.

The golf cart can be quickly split into two relatively compact and lightweight units (as shown in Figures 19 and 20). The splitting method is to pull the release handles 278 on both sides of the second rod (front portion) 266, so that the lock pin (not shown) is ejected from the hole 264 of the frame 230, and the front rod is raised to make the bottom protrusion 274 from the bracket. The 260 is disengaged from the engaged position of the pin 262. Referring to the twentieth diagram, the split lever device S, the push/ride unit V and the link system T, the golf bag 236, and the golf club 279 can be conveniently placed in the trunk of the vehicle.

As shown in the twenty-first and twenty-second figures, the foldable seat 280 can be mounted to the cart as an alternative component. The folded state of the foldable seat 280 is as shown in Fig. 21, and the state at the time of use is as shown in Fig. 22. The pull-out handle 282 can lock the extension portion 284 in the hollow rod 208, one end of a connecting rod 286 is pivoted by a pivot pin or a pivot bolt 263, and the other end is passed through a pivot pin or pivot bolt 288 and an extension portion 284 shaft. Pick up. The seat is also pivoted by the pivot pin or pivot bolt 288 described above, and in use, a one-way release spring lock (not shown) will maintain the position after the seat is raised.

It can be clearly seen from the drawings of the embodiment of the present invention that when the operation mode of the cart is the driving mode, the footboard 24 or 204 is very close to the ground, which is related to the characteristics of the driving device, the driving The devices R and L are mechanically independent of each other. The action of getting the car no longer requires a differential device and a lateral drive shaft. The area between the two drives provides space for the footrests 24 or 204, which allows the center of gravity of the vehicle to remain in a lower position even when the user is in a standing driving state. It can be further seen from the figure that the wheelbase of the front and rear wheels of the vehicle in the driving mode is significantly larger than the wheelbase of the front and rear wheels in the walking mode, which makes it possible to improve the grip performance of the wheels (three or four) when the vehicle is heavily loaded. On the other hand, the load of the car is not large in the walking mode, and the short track makes the car easy to control and manipulate. The grab bars 60 or 216 are ergonomically designed in both modes of operation, allowing the user to walk or drive comfortably.

As described above, the dual mode golf cart of the present invention can be conveniently switched between the two modes, and the driving in both modes can maintain high efficiency, and the wheelbase in the walking mode is 30% shorter than the driving mode and the ball The car can be transported very easily.

The golf cart of the present invention is suitable for the civilian field, such as a warehouse, a shopping mall, etc., because of its high mobility, and is also suitable for long-distance loading and transportation.

The features and spirit of the present invention will be more apparent from the detailed description of the preferred embodiments. The present invention is not limited thereto, and various changes and equivalent arrangements may be made without departing from the spirit and scope of the invention.
