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

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

Specifically, the first guide member is a guide rack 310 respectively disposed on the outer wall of each support column 101 along the height direction of each support column 101, the second guide member is rotatably connected to the bottom surface of the lower lifting platform 220 and is matched with and connected to guide racks 310 to form guide gears 320, and the number of the guide racks 310 and the guide gears 320 is four and corresponds to one.

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 rotation synchronization of the guide gears 320, two guide gears 320 parallel to the length direction of the lifting platform are connected through a guide rod 330; at least one synchronizing wheel 340 is respectively arranged on the two guide rods 330, and the two synchronizing wheels 340 are connected through a synchronizing belt 350.

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

The guide bar 330 and the synchronizing wheel 340 connect the guide gears 320, thereby achieving the synchronous rotation of the guide gears 320.

In order to ensure accurate synchronization process, two synchronizing wheels 340 are arranged on each guide rod 330, the synchronizing wheels 340 are respectively arranged at two ends of the guide rods 330, the two synchronizing wheels 340 at the same end of the two guide rods 330 are connected through a synchronizing belt 350, the synchronizing wheels 340 are of a gear structure, and the synchronizing belt 350 is of a rack structure.

As shown in fig. 5, in order to prevent the timing belt 350 from being loosened due to too long service time or from being mounted in a deviation during the mounting process, a tensioning member 360 is further disposed at the bottom of the lower lifting platform 220, and the tensioning member 360 is used for adjusting the tightness of the timing belt 350.

In order to ensure the balance of the synchronous belt 350, a group of tensioning members 360 are respectively arranged at two sides of the annular synchronous belt 350, so that the tightness of the two sides of the synchronous belt 350 is synchronously adjusted, and the stable movement is ensured.

The transition wheel 362 is formed with a limiting groove 3621 extending inwards along the circumferential direction, and the synchronous belt 350 is positioned in the limiting groove 3621, so that the connection accuracy of the synchronous belt 350 and the transition wheel 362 is ensured.

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

The positioning device 400 comprises a positioning base 410 for providing a supporting function, a positioning piece 420 connected with the lifting device 200 and used for being clamped on the positioning base 410, and a positioning driving piece for driving the action of the positioning piece 420.

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

For example, when the number of the lifting tables on the lifting device 200 is two, the number of the positioning bases 410 may be set to one, and in the initial state, the upper lifting table 230 is flush with the ground, when the vehicle needs to be parked on the lower lifting table 220, the lifting device 200 drives the lower lifting table 220 to be raised to be flush with the ground, at this time, the positioning member 420 is supported above the positioning bases 410, the vehicle is parked on the lower lifting table 220, and then the lifting device 200 drives the vehicle and the lower lifting table 220 to be lowered 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 be n-1, in an initial state, the upper lifting platform 230 is flush with the ground, when a vehicle is parked on the nth lifting platform from the bottom, the lifting device 200 drives the nth lifting platform to rise to be flush with the ground, at this time, the positioning piece 420 is positioned on the nth positioning base 410 from bottom to top, at this time, the nth lifting platform is flush with the ground, so that the parking is convenient.

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

in this case, each support column 101 is formed with a positioning base 410, and the lower lifting platform 220 is exposed to the ground when the positioning member 420 is positioned on the positioning base 410.

Referring again to fig. 7, a guide slope 421 and a supporting surface 422 are formed on the positioning member 420, a connection plate 401 is fixed on the lower lifting table 220, and the positioning member 420 is hinged with the connection plate 401;

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 middle link 450 has a long length, a support plate 451 is provided at the bottom of the lower stage 220, and an arc-shaped support opening is formed in the support plate 451, and the middle link 450 is inserted into the support opening to provide support for the middle link 450.

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

Along with the expansion and contraction of the positioning driving member, the intermediate link 450 drives the adaptor 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 affecting the lifting motion of the lifting device 200, and when the positioning members 420 smoothly pass through the positioning base 410 in the lifting process, the positioning driving member controls each positioning member 420 to reversely rotate, so as to return the positioning members 420.

In other embodiments of the present application, in addition to relying entirely on the positioning drive to control rotation of the positioning member 420, the positioning member 420 may also be configured to automatically rotate and reset during the ascent.

Specifically, a reset portion is formed between the positioning element 420 and the connection plate 401, and is used for resetting the positioning element 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 up under the action of the lifting driving member 470, the guiding inclined plane 421 is in contact with the positioning base 410, and the positioning member 420 is rotated counterclockwise under the action of the positioning base 410, avoiding the interference of the positioning base 410, and moves upwards.

After the positioning piece 420 moves to be higher than the positioning base 410, the positioning piece 420 rotates to reset under the action of the resetting part; then, the lifting driving member 470 controls the lifting support 210 to drive the lower lifting platform 220 to descend until the supporting surface 422 contacts the positioning base 410, and the positioning member 420 is supported and fixed by the positioning base 410, so as to complete 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 450, 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 the initial state, the limit post 442 is located at one end (leftmost end in fig. 11) of the avoidance groove 452, during the lifting process of the lifting device 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 switching portion 440 rotates clockwise, the limit post 442 rotates rightward in the avoidance groove 452, the intermediate link 450 is always stationary, and the avoidance groove 452 acts to avoid interference with the positioning driving member.

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