[0052] The first embodiment of the present application provides an electric vehicle. Figure 1 and Figure 7 The electric vehicle 10 includes a vehicle body 11, a first column 12, a second column 13, a handlebar 14, a seat 15, and a connecting rod mechanism 16. The first column 12 and the second column 13 are both movably connected to the vehicle body 11, the handlebar 14 is mounted on the first column 12, and the seat 15 is mounted on the second column 13; the connecting rod mechanism 16 connects the first column 12 and the second column 13 to realize the linkage of the first column 12 and the second column 13, thereby realizing the folding or unfolding of the first column 12 and the second column 13.

[0053] The electric vehicle 10 travels in a front-to-back direction, and the first pillar 12 and the second pillar 13 are arranged at intervals in the front-to-back direction.

[0054] The structure of the vehicle body 11 is not limited in this application, as long as the vehicle body 11 can be equipped with the first column 12, the second column 13, the connecting rod mechanism 16 and the driving device 17; wherein the vehicle body 11 is provided with an energy storage device for supplying power to the electric vehicle 10, such as an energy storage battery.

[0055] Optionally, the lower end of the first column 12 is rotatably connected to the vehicle body 11 so that the upper end of the first column 12 can swing up and down, and the first column 12 has a through hole extending along its length, and the handlebar 14 is inserted into the through hole of the first column 12 from the upper end of the first column 12; wherein the handlebar 14 can rotate relative to the first column 12 to adjust the direction of the front wheel 111.

[0056] Optionally, the lower end of the second column 13 is connected to the vehicle body 11 by rotating around a horizontal axis, so that the upper end of the second column 13 can swing up and down, and the seat 15 is installed on the upper end of the second column 13; it can be understood that the seat 15 can be installed on the upper end of the second column 13 by welding, fastener connection, clamping, etc. When the seat 15 is connected to the upper end of the second column 13 by fasteners, the height and pitch angle of the seat 15 can be adjusted by loosening the fasteners to suit different people. After the adjustment is in place, the fasteners can be tightened.

[0057] The first column 12 and the second column 13 are linked, which means that the first column 12 and the second column 13 can move together under the drive of the connecting rod mechanism 16 to achieve synchronous unfolding and folding, which can reduce the number of driving devices 17, simplify the structure and reduce costs.

[0058] Optionally, the electric vehicle 10 may be a two-wheeled electric vehicle, a three-wheeled electric vehicle, or the like.

[0059] The electric vehicle 10 provided in the embodiment of the present application connects the first column 12 and the second column 13 through a connecting rod mechanism 16 to realize the linkage of the two columns, so that the first column 12 with the handlebar 14 installed and the second column 13 with the seat 15 installed can be folded toward the vehicle body 11 to reduce the height of the electric vehicle 10, reduce the size of the electric vehicle 10, and solve the problem of the electric vehicle 10 occupying more space when parked. Moreover, after the height of the electric vehicle 10 is reduced, its center of gravity is also lowered, and the stability is higher during remote control driving and automatic driving.

[0060] Please refer to Figure 1 In some embodiments, the electric vehicle 10 further includes a driving device 17 disposed on the vehicle body 11, and a driving end of the driving device 17 is connected to the first column 12, the second column 13 or the connecting rod mechanism 16 to drive the first column 12 and the second column 13 to fold or unfold.

[0061] It can be understood that the driving device 17 can be connected between the vehicle body 11 and the first column 12 to drive the first column 12 to move, and at the same time drive the second column 13 to move through the connecting rod mechanism 16; or, the driving device 17 can be connected between the vehicle body 11 and the second column 13 to drive the second column 13 to move, and at the same time drive the first column 12 to move through the connecting rod mechanism 16; or, the driving device 17 can be connected between the vehicle body 11 and the connecting rod mechanism 16 to drive the connecting rod mechanism 16 to move, and at the same time drive the first column 12 and the second column 13 to move.

[0062] The driving device 17 drives the first column 12 and the second column 13 to automatically fold or unfold, which is labor-saving and does not require manual operation by the user, thereby improving the user experience.

[0063] In other embodiments, the driving device 17 may not be provided, and the first column 12 and the second column 13 may be folded or unfolded manually; in this case, a manual locking member needs to be provided between the connecting rod mechanism 16 and the first column 12 or between the connecting rod mechanism 16 and the second column 13 to lock the first column 12 and the second column 13 in this position after folding or unfolding. For example, the manual locking member may be a locking bolt, and the first column 12 is provided with a first through hole and a second through hole, and the slider 1611 is provided with a threaded hole; when in the unfolded state, the first through hole is aligned with the threaded hole, and the locking bolt passes through the first through hole and is screwed into the threaded hole to lock the slider 1611; when in the folded state, the second through hole is aligned with the threaded hole, and the locking bolt passes through the second through hole and is screwed into the threaded hole to lock the slider 1611.

[0064] In some embodiments, the driving device 17 is a telescopic device.

[0065] Optionally, the telescopic device is an electric telescopic device, such as an electric telescopic cylinder, an electric push rod, etc., wherein the electric telescopic device can utilize the energy storage device of the electric vehicle 10. Of course, the telescopic device can also be a pneumatic telescopic device, such as a cylinder; the telescopic device can also be a hydraulic telescopic device, such as a hydraulic cylinder.

[0066] By adopting the above technical solution, after being folded, the size of the telescopic device is reduced to avoid occupying too much space.

[0067] In other embodiments, the driving device 17 may be a screw-nut mechanism.

[0068] Please refer to Figure 1 In some embodiments, the connecting rod mechanism 16 includes a first connecting rod 161 and a second connecting rod 162. The first end of the first connecting rod 161 is slidably installed and limited on the first column 12, and the middle part of the first connecting rod 161 is movably connected to the second column 13; the first end of the second connecting rod 162 is movably connected to the vehicle body 11, and the second end of the second connecting rod 162 is movably connected to the second end of the first connecting rod 161.

[0069] The first end of the first connecting rod 161 is slidably installed and limited on the first column 12, which means that the first end of the first connecting rod 161 slides on the first column 12 along the length direction of the first column 12, and the first end of the first connecting rod 161 will not be separated from the first column 12 during the sliding process on the first column 12, that is, the first end of the first connecting rod 161 always remains connected with the first column 12 during the sliding process on the first column 12.

[0070] Optionally, the middle part of the first connecting rod 161 is rotatably connected to the middle part of the second column 13; wherein the middle part of the first connecting rod 161 refers to the part between the first end and the second end of the first connecting rod 161, and the middle part of the second connecting rod 162 refers to the part between the first end and the second end of the second connecting rod 162.

[0071] Optionally, the first end of the second link 162 is rotatably connected to the vehicle body 11, and the second end of the second link 162 is rotatably connected to the second end of the first link 161; it can be understood that the second link 162 is located at the rear lower side of the second column 13, and the first link 161 is sequentially connected to the first column 12, the second column 13 and the second link 162 from front to back. Among them, the vehicle body 11, the second column 13, the first link 161 and the second link 162 constitute a four-bar linkage.

[0072] Optionally, a driving device 17 is provided between the vehicle body 11 and the second column 13. It can be understood that the lower end of the driving device 17 is rotatably connected to the vehicle body 11, and the upper end of the driving device 17 is rotatably connected to the second column 13. The driving device 17 is not only used to drive the first column 12 and the second column 13 to unfold and fold, but also plays a role in supporting the second column 13 when the first column 12 and the second column 13 are unfolded. Of course, the driving device 17 can also be provided between the vehicle body 11 and the second connecting rod 162.

[0073] During operation, the second column 13 is driven to move by the driving device 17 , and the second column 13 drives the first column 12 to move through the first connecting rod 161 , and the second connecting rod 162 moves with it, so as to realize the unfolding and folding of the first column 12 and the second column 13 .

[0074] By adopting the above technical solution, the connecting rod mechanism 16 only includes the first connecting rod 161 and the second connecting rod 162, so that the structure of the connecting rod mechanism 16 is relatively simple.

[0075] Please also refer to Figure 8 and Fig. 9 In some embodiments, the connecting rod mechanism 16 includes not only the first connecting rod 161 and the second connecting rod 162 mentioned above, but also includes a third connecting rod 163, the first end of the third connecting rod 163 is slidably mounted on the vehicle body 11, and the second end of the third connecting rod 163 is movably connected to the second column 13.

[0076] Optionally, a driving device 17 is provided between the vehicle body 11 and the third connecting rod 163, and the driving device 17 is horizontally placed on the vehicle body 11 along the front-to-back direction, the front end of the driving device 17 is connected to the vehicle body 11, and the rear end of the driving device 17 is connected to the first end of the third connecting rod 163 to drive the first end of the third connecting rod 163 to slide on the vehicle body 11 along the front-to-back direction.

[0077] During operation, the driving device 17 drives the first end of the third connecting rod 163 to slide in the front-to-back direction, the second end of the third connecting rod 163 drives the second column 13 to move, the second column 13 drives the first column 12 to move through the first connecting rod 161, and the second connecting rod 162 moves with it to realize the unfolding and folding of the first column 12 and the second column 13.

[0078] The second end of the third connecting rod 163 is rotatably connected to the second column 13, that is, the third connecting rod 163 replaces the driving device 17 to support the second column 13. The third connecting rod 163 is an integrated structure with high structural strength. Compared with the driving device 17, the third connecting rod 163 has better stability when supporting the second column 13; and the driving device 17 is only used to drive the first column 12 and the second column 13 to unfold and fold, and no longer supports the second column 13. In this way, the force on the driving device 17 is relatively small, which improves the service life of the driving device 17 and reduces the risk of failure of the first column 12 and the second column 13 to unfold or fold due to damage to the driving device 17.

[0079] Please also refer to Figure 2 and Figure 3 In some embodiments, the first column 12 is provided with a shrinking groove 121 extending along the length direction thereof, and a slider 1611 slidably matched with the shrinking groove 121 is movably mounted on the first end of the first connecting rod 161 .

[0080] The shrinking groove 121 refers to a groove whose groove width is smaller than its groove bottom width, for example, the shrinking groove 121 can be a T-shaped groove, a dovetail groove, etc. Correspondingly, the slider 1611 is adapted to the shrinking groove 121 to avoid the problem of stagnation during the sliding process.

[0081] Optionally, the slider 1611 is rotatably connected to the first end of the first connecting rod 161 .

[0082] The first end of the first connecting rod 161 can be slidably mounted and limited on the first column 12 by the sliding cooperation between the shrinking groove 121 and the sliding block 1611 .

[0083] In other embodiments, the shrinkage groove 121 may not be provided on the first column 12, but a through hole is provided on the slider 1611. The slider 1611 is sleeved on the first column 12 and can slide on the first column 12. In this way, the first end of the first connecting rod 161 can be slidably installed and limited on the first column 12.

[0085] Optionally, the electric vehicle 10 may be a reverse three-wheel electric vehicle, that is, two front wheels 111 are provided, and one rear wheel 112 is provided. Among them, two front shock absorbers 113 are provided, and the two front shock absorbers 113 are respectively arranged corresponding to the two front wheels 111 and are located between the two front wheels 111; two rear shock absorbers 114 are provided, and the two rear shock absorbers 114 are respectively located on both sides of the axial direction of the rear wheel 112.

[0087] By arranging a front shock absorber 113 between the front wheel 111 and the vehicle body 11 , and arranging a rear shock absorber 114 between the rear wheel 112 and the vehicle body 11 , the electric vehicle 10 can adapt to certain off-road surfaces, which is beneficial for off-road driving of the electric vehicle 10 .

[0088] In other embodiments, the front shock absorber 113 may be provided only between the front wheel 111 and the vehicle body 11; or, the rear shock absorber 114 may be provided only between the rear wheel 112 and the vehicle body 11; or, no shock absorber may be provided between the front wheel 111 and the vehicle body 11 and between the rear wheel 112 and the vehicle body 11.
