Description

Linkage structure of Suikeda locomotive

The present invention relates to a linkage structure of a skating locomotive, and more particularly to a device that can reduce the length of the skating locomotive and automatically support the pedestal when the length of the locomotive is reduced.

In the modern metropolis where traffic is crowded, the Sukhtec locomotive is chosen by the general public as a means of transportation. Throughout the current speed, the distance of the vehicle is fixed and unchangeable. Whether it is manufacturing a car manufacturer or a user, it is naturally impossible to increase the efficiency of the space for the carriage or parking of the Scooter locomotive, especially in the case of a family with several Scooters. The lack of parking space is often a big problem.

In view of the above problems, the creators of this case created the case with the spirit of excellence.

The purpose of the creation of this case is to improve the length and telescopic function of the Suikeda locomotive and the automatic retraction of the tripod, which causes the inconvenience of the Suikeda locomotive to be used during parking, and provides a speed for the speed of the locomotive. When it is reduced, the tripod can automatically support the interlocking structure.

In order to achieve the purpose, the present invention comprises two parts of a front wheel segment and a rear wheel segment; a cross bar is arranged below the front wheel segment, a sliding rail is integrally extended at a side end of the cross bar, and a rack is arranged on the upper end surface of the sliding rail, and A putter is placed in the middle of the second slide rail. A frame is arranged below the rear wheel segment, and a pedal is arranged at the front end of the frame. The push rod can be used to close or close the pedal according to the hinge mechanism. One side of the frame is provided with a transmission mechanism group, and the transmission mechanism group is driven. It can drive the rack end of the slide rail to change the distance between the front wheel segment and the rear wheel segment; in particular, the transmission mechanism group can drive the fan-shaped tooth row of the tripod, so that the tripod rotates according to the pivot point, thereby The Scooter locomotive can be erected automatically.

BRIEF DESCRIPTION OF THE DRAWINGS In order to achieve the above object, the present invention is a schematic view of a preferred embodiment of the present invention as illustrated in the first drawing, and is described in detail below. Please refer to the perspective view of the preferred embodiment of the present invention shown in the first figure. The second figure shows a plan view of the preferred embodiment of the present invention. The structure of the speed skating locomotive of the present case is divided into two parts, a front wheel segment 10 and a rear wheel segment 20; wherein the front wheel segment 10 includes a keel of the skating locomotive, a front frame, a front fork, a front wheel set and a front car block a portion such as a plate, and a cross bar 11 is disposed below the front wheel segment 10, and two rails 12 are integrally extended on both sides of the cross bar 11, and a rack 13 is disposed on the upper end surface of the slide rail 12, and is disposed in the middle of the second slide rail 12 There is a putter 14 in place. The rear wheel section 20 includes a rear frame of the Scooter locomotive, a seat cushion, a power output device (engine or electric motor), a rear wheel set and a rear car shell, and the like, and a hollow is provided below the rear wheel segment 20. The frame 21 is provided with a pedal 22 at the front end of the frame 21, and the push rod 14 can be lifted or flattened by the hinge mechanism 23; the transmission mechanism is provided on one side of the frame 21. The transmission mechanism group 24 is coupled to a worm by a shaft of a motor, and drives a worm wheel 241 and its shaft to rotate by a worm. The shaft is provided with a driving gear 242 on both sides thereof, and the driving gear 242 is connected to the sliding rail 12 The end rack's rack 13 engages the motor of the transmission mechanism 24 to be acted upon by a start switch at the handle. Please refer to the third FIG. 4, and FIG. 5 are schematic diagrams showing the structure and operation of the stand. The transmission mechanism group 24 of the rear wheel segment 20 is provided with a second transmission gear 243 on the axial center side of the worm wheel 241. The second transmission gear 243 can be rotated by the transmission mechanism group 24; the rear wheel segment The bottom of the 20 is provided with a tripod 25 which can be folded or erected according to a pivot point 251 to provide support for the vehicle body. In particular, one side of the tripod 25 is provided with a sector-shaped tooth row 252. The sector-shaped tooth row 252 is just engaged with the second transmission gear 243 to form a linkage relationship therebetween.

Therefore, by the transmission of the transmission mechanism group 24, the rack 13 of the end surface of the slide rail 12 can be driven to displace the two slide rails 12 to the rear side under the support and the limit of the frame 21, thereby reducing the speed of the locomotive locomotive. Length; if the speed of the locomotive locomotive is restored to the original state, it is only necessary to restart the transmission mechanism group 24 to reverse the operation, so that the speed locomotive locomotive returns to the normal length, thereby achieving the purpose of expansion and contraction. In addition, when the transmission mechanism group 24 is driven to move the crossbar 11 of the front wheel segment 10 backward, the second transmission gear 243 then drives the sector-shaped tooth row 252, so that the foot frame 25 is lowered according to the pivot point 251, thereby enabling the quick-fixing The locomotive can be erected automatically to achieve the purpose of supporting the speed locomotive.

According to the structure of the front wheel section 10 and the rear wheel section 20 in the above-mentioned case, the transmission mechanism group 24 of the rear wheel section 20 is used to drive the worm wheel 241, the drive gear 242 and the second transmission gear 243 of different numbers of teeth to achieve the same rotation. The number, which in turn drives the rack 13 of the end surface of the slide rail 12, causes the slide rail 12 to be displaced to the rear side under the support and the limit of the frame 21, and the slide rail 12 is displaced, that is, The second transmission gear 243 can drive the sector-shaped tooth row 252 to rotate the foot frame 25 according to the pivot point 251, that is, the slide rail 12, the pedal 22 and the foot frame 25 are simultaneously actuated, thereby facilitating the erecting action of the tripod of the speed locomotive parking. There is no need for personnel to manually step on and push heavy locomotives. The parking process of the Scoda locomotive is fully automated. Of course, if the speed locomotive is to be returned to the original state, the transmission mechanism group 24 is activated to reverse the operation, so that the locomotive can return to the running state.

In summary, with the device of the present invention, in addition to providing the telescopic function of the Scooter locomotive, the automatic stand stand can be achieved, and the laborious problem of parking at the time of parking is solved, thereby greatly improving the integrity and practicality of the product. value. However, it is apparent that the description of the present invention in the above embodiments, and the drawing of the present invention in the drawings, are merely preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; Equivalent changes or modifications made by those skilled in the art without departing from the spirit of the invention are intended to be included within the scope of the appended claims. Compared with the conventional ones, the case has significant progress and industrial utilization, and the technical means and structural features used in the present invention are indeed developed by the inventor of the present case, so the case has met the requirements of the patent. , 提出 apply in accordance with the law, and pray for patent rights.
