Of course, the lifting driving member 470 may be other driving devices, such as an electric push rod, which can provide lifting power for the lifting frame 210.

As shown in fig. 3 and 4, the guiding device 300 is used to improve the stability of the lifting bracket 210 during the lifting process, and specifically, it includes a first guiding member disposed on each supporting column 101 and a second guiding member disposed on the lifting platform and adapted to each first guiding member.

In the lifting process of the lifting device 200, the guide gears 320 are lifted along the guide racks 310, and in order to realize the rotation synchronization of the guide gears 320, the two guide gears 320 parallel to the length direction of the lifting platform are connected through the guide rod 330; at least one synchronous wheel 340 is respectively arranged on the two guide rods 330, and the two synchronous wheels 340 are connected through a synchronous belt 350.

The synchronizing wheel 340 is fixed to the guide 330 to rotate in synchronization with the guide 330.

The guide rod 330 and the synchronizing wheel 340 connect the guide gears 320 to each other, thereby achieving synchronous rotation of the guide gears 320.

As shown in fig. 5, in order to prevent the synchronous belt 350 from loosening due to an excessively long use time or from generating installation deviation in the installation process, a tension member 360 is further disposed at the bottom of the lower-layer lifting platform 220, and the tension member 360 is used for adjusting tightness of the synchronous belt 350.

In order to ensure the balance of the synchronous belt 350, a set of tensioning members 360 are respectively arranged on two sides of the annular synchronous belt 350, so as to synchronously adjust the tightness of the two sides of the synchronous belt 350 and ensure stable movement.

As shown in fig. 6 to 13, after the lifting device 200 drives the lifting platform to rise to the target height, in order to ensure the stability of the lifting device 200 at the target position, a positioning device 400 is provided.

The positioning device 400 includes a positioning base 410 for providing a supporting function, a positioning member 420 connected to the lifting device 200 and adapted to be clamped on the positioning base 410, and a positioning driving member for driving the positioning member 420.

The positioning member 420 is installed on the lower lifting platform 220, the positioning bases 410 are fixed on the supporting columns 101, and the number of the positioning bases 410 on each supporting column 101 can be set according to specific requirements.

For example, when the number of the lifting platforms on the lifting device 200 is two, the number of the positioning bases 410 may be set to one, in the initial state, the upper lifting platform 230 is flush with the ground, when the vehicle needs to be parked on the lower lifting platform 220, the lifting device 200 drives the lower lifting platform 220 to ascend to be flush with the ground, at this time, the positioning member 420 is supported above the positioning base 410, the vehicle is parked on the lower lifting platform 220, and then, the lifting device 200 drives the vehicle and the lower lifting platform 220 to descend into the underground parking space.

When the number of the lifting platforms on the lifting device 200 is n, the number of the positioning bases 410 can be set to n-1, under the initial state, the upper lifting platform 230 is flush with the ground, when the vehicle stops on the nth lifting platform counted from the bottom, the lifting device 200 drives the nth lifting platform to ascend to be flush with the ground, at this moment, the positioning piece 420 is positioned on the nth positioning base 410 from the bottom, at this moment, the nth lifting platform is flush with the ground, and the parking is convenient.

The following describes the positioning process of the positioning member 420 in detail, taking the lifting platform as an example of two layers:

in this case, a positioning base 410 is formed on each supporting column 101, and when the positioning member 420 is positioned on the positioning base 410, the lower elevating platform 220 is exposed from the ground.

Referring to fig. 7 again, a guide inclined plane 421 and a support plane 422 are formed on the positioning member 420, a connection plate 401 is fixed on the lower lifting platform 220, and the positioning member 420 is hinged to the connection plate 401;

in order to realize the synchronous movement of the positioning members 420 on the lower lifting platform 220, an adapter portion 440 is formed between the two positioning members 420 perpendicular to the length direction of the lifting platform, and a pull rod 430 is formed between the two positioning members 420 and the adapter portion 440.

The two adapter parts 440 parallel to the length direction of the lifting platform are connected through an intermediate connecting rod 450, and the intermediate connecting rod 450 is rotatably connected to the bottom of the lifting platform through a bearing seat 460.

Referring again to fig. 10, since the intermediate link 450 has a long length, a support plate 451 is disposed at the bottom of the lower lift stage 220, an arc-shaped support opening is formed in the support plate 451, and the intermediate link 450 is inserted into the support opening to provide support for the intermediate link 450.

The positioning driving member is connected with the middle connecting rod 450 through the arc-shaped plate, and two ends of the positioning driving member are respectively hinged with the arc-shaped plate and the lower-layer lifting platform 220.

With the extension and retraction of the positioning driving member, the intermediate connecting rod 450 drives the adapting portion 440 to rotate, and further drives the positioning member 420 to rotate.

The positioning driving member can control the rotation of each positioning member 420, so as to avoid the positioning base 410 and avoid influencing the lifting motion of the lifting device 200, and when the positioning members 420 pass through the positioning base 410 smoothly in the lifting process, the positioning driving member controls the positioning members 420 to rotate reversely, so as to return the positioning members 420.

In other embodiments of the present application, instead of relying on the positioning driving member to control the rotation of the positioning member 420, the positioning member 420 may be automatically rotated and reset during the ascending process through its own structure.

Specifically, a reset part is formed between the positioning member 420 and the connecting plate 401, and is used for resetting the positioning member 420 after rotating;

the reset part is a torsion spring, one end of the torsion spring is fixed with the connecting plate 401, and the other end of the torsion spring is fixed with the positioning piece 420;

the lifting device 200 is lifted by the lifting driving member 470, the guiding inclined plane 421 contacts the positioning base 410, and the positioning member 420 rotates counterclockwise under the action of the positioning base 410 to avoid the interference of the positioning base 410 and move upward.

After the positioning member 420 moves to be higher than the positioning base 410, the positioning member 420 rotates to be reset under the action of the resetting part; then, the lifting driving member 470 controls the lifting bracket 210 to drive the lower lifting platform 220 to descend to the supporting surface 422 to contact with the positioning base 410, and the positioning member 420 is supported and fixed by the positioning base 410, thereby completing the lifting process of the lifting device 200.

A connecting sleeve 441 is further formed between the arc-shaped plate and the intermediate connecting rod 450, an arc-shaped avoiding groove 452 is formed on the intermediate connecting rod 450 along the circumferential direction of the intermediate connecting rod, and a limiting column 442 extending into the avoiding groove 452 is formed in the connecting sleeve 441.

Referring to fig. 11 and 12 again, in an initial state, the limiting column 442 is located at one end (the leftmost end in fig. 11) of the avoiding groove 452, during the ascending process of the lifting apparatus 200, the positioning member 420 rotates counterclockwise under the action of the positioning base 410, at this time, the pull rod 430 connected to the positioning member 420 moves rightward, under the action of the pull rod 430, the adapter 440 rotates clockwise, the limiting column 442 rotates rightward in the avoiding groove 452, the middle link 450 is still, and the avoiding groove 452 prevents interference with the positioning driving member.

After the rising, under the effect of the reset portion, the positioning member 420 rotates clockwise, the pull rod 430 moves to the left, the switching portion 440 rotates counterclockwise, and the limit column 442 returns to the right end of the avoiding groove 452.

Then, the lifting driving member 470 drives the lower lifting platform 220 and the positioning member 420 thereon to move downwards until the supporting surface 422 of the positioning member 420 contacts the positioning base 410.
