Detailed ways

In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

Please refer to Fig. 1, which shows a kind of intelligent displacement and standing vehicle related to the present invention, including a base 1, a rotating pole 2, a handle unit 3, a lifting mechanism 4 and a Power unit 5, wherein:

The base 1 is extended with a vertical rod 11, and the base 1 is also provided with a plurality of moving wheels 12, and the moving wheels 12 can be directly connected with a motor 13 to have the effect of automatic movement;

The rotating rod 2 has a first end 21 and a second end 22, the first end 21 is pivotally connected to the vertical rod 11, the second end 22 is pivotally connected to the handle unit 3, and the rotating The strut 2 is extended with a seat 23;

The lifting mechanism 4 has a gear set 41 and a connecting rod set 42, and the gear set 41 has a fixed base 411, a first gear 412, a second gear 413 and a sector gear 414, the fixed base 411 is fixed On the base 1, the first gear 412 is connected to the power unit 5, and its axis is pivoted on the fixed seat 411. The second gear 413 rotates coaxially with the first gear 412, and the sector gear 414 is meshed with the second gear 413, the axis of which is also pivoted on the fixed seat 411, and the number of teeth of the second gear 413 is smaller than the number of teeth of the first gear 412, the number of teeth of the sector gear 414 is greater than the number of teeth of the second gear 413, and The connecting rod set 42 includes a first driven rod 421 and a second driven rod 422, the first driven rod 421 is pivoted to the sector gear 414, and one end of the second driven rod 422 is pivoted to the first driven rod The other end of the driven rod 421 is connected to the rotating rod 2 , and the second driven rod 422 is longer than the first driven rod 421 .

In terms of use, please refer to Figure 2. When user A wants to ride, he needs to first control the power unit 5 to drive the first gear 412 to rotate clockwise, so that the second gear 413 moves simultaneously to drive the sector The gear 414 rotates counterclockwise, thereby pulling the first driven rod 421 and the second driven rod 422 to move, and then sequentially drives the rotating rod 2 around the base 1 with the first end 211 as a fulcrum. The upright bar 11 rotates clockwise, so that the seat 23 can be tilted downward, so that the user can step on the seat 23 conveniently. The second end 21 rotates counterclockwise to maintain a comfortable holding angle.

Referring to Fig. 3 and Fig. 4 again, after the user A steps onto the seat 23, the power unit 5 is controlled to rotate in the opposite direction, so that the aforementioned gear set 41 and the connecting rod set 42 are rotated in the opposite direction. The seat 23 is lifted to the best sitting position of the user A; when the user A wants to get up, the power unit 5 is continuously activated, the seat 23 is continuously lifted, and the user A is lifted to stand on both feet position, to achieve the effect of assisting user A to get up from the seat.

It is further illustrated that the number of teeth of the gear set 41 is arranged in order of large number of teeth, small number of teeth and large number of teeth by the first gear 412, second gear 413 and sector gear 414. The first driven rod of the connecting rod set 42 The moment arm of 421 is smaller than the moment arm of the second driven rod 422. Through such a design, a large torque value can be output under a small input horsepower value, and when driving the seat 23 to lift, it can carry a larger load At the same time, the connecting rod group 42 utilizes the actuation of the two connecting rods, which will not interfere during the running path of the mechanism.

The above-mentioned embodiments and drawings do not limit the form and style of the product of the present invention, and any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
