[0002] With the increasing number of private cars in cities year by year, parking spaces are extremely limited, and the demand for parking facilities is constantly increasing. As a result, mechanical lift parking garages have emerged. Mechanical lift parking garages can be used on a large scale or installed in gaps, and can be combined with ground parking lots, underground garages, and parking buildings, making them an effective means of solving urban parking difficulties.

[0003] According to invention patent application CN102635261A, published on August 15, 2012, a lifting and traversing type automated parking garage is disclosed, including a frame, a lifting mechanism, and a traversing mechanism. The lifting mechanism includes a first drive mechanism, a drum driven to rotate by the first drive mechanism, a traction rope wound on the drum, and a lifting platform mounted on the traction rope and rising and falling with the traction rope. The traversing mechanism includes a vehicle-carrying fork comb located on the lifting platform for carrying vehicles, and also includes a second drive mechanism that enables the vehicle-carrying fork comb to translate and descend. The frame has a longitudinal slide rail for the longitudinal sliding of the lifting platform and a parking platform for parking vehicles. The parking platform is composed of fixed fork combs that are horizontally staggered with the vehicle-carrying fork comb. Its main technical effect is that it provides a simple, reliable, and safe lifting and traversing type automated parking garage.

[0004] After a vehicle is parked on the car platform inside a lift garage, it needs to be lifted to free up a parking space below. In lift garages installed in outdoor environments, the car platform is suspended on the frame after being lifted, which causes it to sway. To address this issue, a lifting drive mechanism for lift garages is proposed, aiming to solve the problem of swaying inside the frame after the car platform is lifted in the prior art.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1 — Figure 4 A lifting drive mechanism for a lift parking garage includes a frame 1, a drive unit, and a connecting chain. The frame 1 has a car carrier plate 2 inside. The drive unit is mounted on the frame 1. One end of the connecting chain is connected to the output end of the drive unit, and the other end is connected to the car carrier plate 2. The mechanism is characterized by further including an abutment unit 3 disposed inside the frame 1. One end of the abutment unit 3 is slidably connected to the frame 1, and the other end abuts against the car carrier plate 2.

[0022] As an embodiment of the present invention, the frame 1, the drive unit and the connecting chain are all prior art. The drive mechanism provided in this embodiment is used in conjunction with the drive unit in the prior art. The drive unit is set on the frame 1, and the output end of the drive unit is connected to the vehicle platform 2 through the connecting chain. The drive unit drives the vehicle platform 2 to keep moving up and down inside the frame 1.

[0023] As an embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, an abutment unit 3 is provided inside the frame 1. The abutment unit 3 includes a slider 31, a mounting base 32, an adjusting nut 33, and an abutment spring 34. The slider 31 is slidably connected to the frame 1, and the mounting base 32 is fixedly installed on the outer wall of the vehicle platform 2. A threaded guide rod 35 is fixedly installed on the slider 31, and a positioning rod 36 is fixedly installed on the outer wall of one side of the mounting base 32. The mounting base 32 is slidably connected to the threaded guide rod 35 through the positioning rod 36, so that when the vehicle platform 2 moves inside the frame 1, the slider 31 and the mounting base 32 can also move synchronously. The adjusting nut 33 is threadedly connected to the threaded guide rod 35, and the abutment spring 34 is disposed between the adjusting nut 33 and the mounting base 32. The elasticity of the abutment spring 34 drives the mounting base 32 to move to one side, thereby limiting the shaking of the vehicle platform 2 inside the frame 1. As an embodiment provided by this utility model, such as Figure 1As shown, there are four abutment units 3. The four abutment units 3 are respectively set at the four corners of the frame 1 and between the vehicle platform 2, thereby preventing the vehicle platform 2 from shaking during movement and in the upper position.

[0024] As a further embodiment provided by this utility model, such as Figure 3 and Figure 4 As shown, the abutment unit 3 also includes a locking unit 37. Specifically, the locking unit 37 includes a locking head 371 and a drive spring 372. The locking head 371 is slidably connected to the threaded guide rod 35, and the drive spring 372 is disposed between the locking head 371 and the slider 31. The locking head 371 is inserted into the adjusting nut 33. Furthermore, a guide slider is provided on the outer wall of the end of the threaded guide rod 35, and a groove is opened on the circumferential inner wall of the locking head 371. The locking head 371 passes through... The guide slider is slidably connected to the threaded guide rod 35. Several insertion slots 39 are provided on the outer wall of the adjusting nut 33. The insertion slots 39 are arranged in a circular array on the outer wall of the adjusting nut 33. A connector 30 is fixedly installed on the outer wall of the locking head 371. Specifically, there are several connectors 30. The connectors 30 are arranged in a circular array on the outer wall of the locking head 371, and the connectors 30 and the insertion slots 39 can be connected.

[0025] This utility model, by having an abutting unit 3 set inside the frame 1 abut against the outer wall of the vehicle platform 2, prevents the vehicle platform 2 from shaking inside the frame 1 after being lifted, thereby improving the stability of the vehicle platform 2 during lifting and lowering and preventing shaking during lifting and lowering. By enhancing the stability of the vehicle platform 2 when it is moving and stationary, the stability of the vehicle platform 2 inside the frame 1 is greatly enhanced.

[0026] Working principle:

[0027] While the vehicle platform 2 is in the lifting and lowering motion, the abutting unit 3 moves synchronously with the vehicle platform 2. By abutting the vehicle platform 2 with the abutting unit 3, the vehicle platform 2 is prevented from shaking inside the frame 1.

[0028] Rotating the adjusting nut 33 can drive it to move axially along the threaded guide rod 35, thereby adjusting the stroke of the abutment spring 34, adjusting the pressure applied to the mounting base 32, and increasing the stability effect.

[0029] By driving the spring 372 to keep the locking head 371 engaged with the adjusting nut 33, the adjusting nut 33 can be prevented from loosening. When it is necessary to adjust the stroke of the adjusting nut 33, the locking head 371 can be separated from the adjusting nut 33 by using a tool, and the adjusting nut can be rotated.

[0030] The drive spring 372 and the abutment spring 34 mentioned in this article have elastic coefficients that meet the technical requirements of the present utility model.

[0031] Those skilled in the art will understand that other similar connection methods can also achieve this utility model. For example, welding, bonding, or screwing.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
