The first figure is a schematic perspective view of the present invention.

The second figure is a schematic view of the seat being tilted downward to facilitate the user's ride when using the present invention.

The third figure is a schematic view of adjusting the seat to the optimal seating position when the invention is used.

The fourth figure is a schematic view of the seat being tilted upwards to assist the user in getting up when using the present invention.

Combining the above technical features, the main effects of the present invention will be clearly shown in the following embodiments.

Referring to the first figure, it is a smart shifting and standing vehicle comprising a base (1), a rotating strut (2), a grip unit (3), a lifting mechanism (4) and a power unit (5), wherein: the base (1) extends a pole (11), and the base (1) is provided with a plurality of moving wheels (12), and the moving wheel (12) can directly connect the motor ( 13) having an automatic moving effect; the rotating strut (2) has a first end (21) and a second end (22), and the first end (21) is pivotally connected to the pole (11) The second end (22) is pivotally connected to the grip unit (3), and the rotating strut (2) extends and defines a seat (23); the lifting mechanism (4) has a gear set (41) And a link set (42), the gear set (41) has a fixed seat (411), a first gear (412), a second gear (413) and a sector gear (414), the fixed seat (411) is fixed to the base (1), the first gear (412) is connected to the power unit (5), and its axis is pivotally disposed on the fixed seat (411), the second gear (413) and the first A gear (412) rotates coaxially, and the sector gear (414) is meshed with the second gear (413), and its axis is also pivoted to the solid a seat (411), wherein the second gear (413) has a smaller number of teeth than the first gear (412), the sector gear (414) has a larger number of teeth than the second gear (413), and the link (42) includes a first follower rod (421) and a second follower rod (422) pivotally connected to a circumference of the non-axis center of the sector gear (414), the second follower rod (422) one end pivotally connects the first follower rod (421), the other end is connected to the rotating strut (2), and the second follower rod (422) is longer than the first follower rod (421).

In use, please refer to the second figure. When the user (A) wants to ride, the power unit (5) is first controlled to drive the first gear (412) to rotate clockwise to make the second gear (413). Simultaneously, the sector gear (414) is driven to rotate counterclockwise, thereby pulling the first driven rod (421) and the second driven rod (422) to actuate, and then sequentially driving the rotating rod (2) Using the first end (211) as a fulcrum, and rotating the pole (11) around the base (1) clockwise, whereby the seat (23) is tilted downward for the user to conveniently straddle the The seat (23), while the user can hold the grip unit (3) to rotate counterclockwise around the second end (21) of the rotating strut (2), and can maintain the comfortable grip angle.
