Description

Technical Field

[0001] This utility model relates to the field of parking lock technology, and in particular to a parking lock. Background Technology

[0002] A parking lock is a mechanical device whose main function is to prevent unauthorized occupancy of a specific parking space, ensuring that parking users can park at any time. With the acceleration of urbanization and the increase in car ownership, parking locks, as an important parking management device, are being used more and more widely. However, traditional parking locks have some inherent design flaws, especially the inability to adjust the height of the lock's baffle. This problem significantly limits the versatility and practicality of parking locks. The baffle height of traditional parking locks is usually fixed and cannot be flexibly adjusted according to the height of the vehicle. This means that in actual use, the parking lock baffle may not be able to effectively block or lock vehicles of different heights (such as sedans, SUVs, trucks, etc.). For taller vehicles, the baffle may be too low to provide effective blocking, and may even be damaged by being run over.

[0003] Because the barrier height is fixed, parking locks often rely on a single physical obstruction method to lock. When subjected to external impact or malicious damage, this single physical obstruction method can be easily overcome, causing the parking lock to malfunction. Furthermore, since the barrier height cannot be adjusted, the locking effect of the parking lock will vary when dealing with vehicles of different weights, thus affecting the stability and reliability of the parking lock.

[0004] Therefore, this application develops a parking space lock to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a parking space lock to solve the problem that the parking space lock baffle cannot be adjusted in the prior art.

[0006] The technical solution of this utility model is: a parking space lock, comprising:

[0007] A fixed housing, installed on the ground;

[0008] A driving device, comprising a driving end and a driven end, wherein the driving end is disposed on the outer wall surface of the fixed housing, and the driven end is located inside the fixed housing and passes through the fixed housing and is connected to the driving end;

[0009] A rotating assembly includes a rotating rod and a multi-layer baffle assembly. The rotating rod is rotatably connected to the driven end via a driving part. The multi-layer baffle assembly is fixedly mounted on the rotating rod. When the driving device moves, the rotating rod rotates under the drive of the driving end, thereby causing the multi-layer baffle assembly to move together with the rotating rod. During the movement, each layer of the baffle assembly gradually slides out in sequence, thereby increasing the overall height of the baffle assembly.

[0010] Preferably, the drive unit includes a slide plate, a connecting rod, and a push rod. The slide plate is rotatably connected to the driven end and can move along the driven end. One end of the push rod is fixed to the rotating rod. The two ends of the connecting rod are respectively connected to the other end of the push rod and the slide plate by rotation. When the slide plate moves along the driven end, the push rod rotates under the linkage of the connecting rod, and the rotation direction of the push rod is opposite to the rotation direction of the connecting rod relative to the slide plate.

[0011] Preferably, when the slide is in the initial position, the baffle assembly is tilted downwards, and the push rod and the connecting rod are on the same straight line.

[0012] Preferably, the baffle assembly includes a first baffle, a second baffle, and a third baffle stacked sequentially. A first torsion spring and a second torsion spring connected to the second baffle and the third baffle are respectively provided on the rotating rod. The second baffle is slidably disposed on the first baffle, and the third baffle is slidably disposed on the second baffle, forming a multi-layer sliding baffle structure.

[0013] Preferably, the first baffle has a groove in the middle to provide installation space for the first torsion spring and the second torsion spring, and when the baffle assembly is not moving, the orthogonal projections of the second baffle and the third baffle onto the first baffle fall completely within the first baffle.

[0014] Preferably, both the first torsion spring and the second torsion spring are in a tensioned state, and the length of the first torsion spring is less than the sliding distance of the second baffle, and the length of the second torsion spring is less than the total sliding distance of the second baffle and the third baffle.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) The baffle assembly consists of three layers of baffles stacked in sequence. Through a specific sliding and connection mechanism, a multi-layered and flexibly sliding structure is formed. The second baffle can slide relative to the first baffle, and the third baffle can slide relative to the second baffle. With the help of the first torsion spring and the second torsion spring, the sliding and resetting of each baffle can be flexibly controlled, so as to realize the flexible change of the height of the baffle assembly.

[0017] (2) When the parking lock is not in operation, the baffle assembly is tilted downwards, and the push rod and the connecting rod are on the same straight line. The mechanical structure formed by this special positional relationship can more effectively withstand the pressure exerted on the baffle assembly during the driving or parking of the car, so that the whole structure has better rigidity and stability when dealing with pressure.

[0024] The present invention will be further described in detail below with reference to specific embodiments:

[0025] like Figure 1 As shown, a parking lock includes a fixed housing 1, a drive unit 2, and a rotating assembly 3. The fixed housing 1 is installed on the ground and serves as the basic support structure for the entire parking lock. The drive unit 2 includes a drive end 21 and a driven end 22. The drive end 21 is disposed on the outer wall of the fixed housing 1, while the driven end 22 is located inside the fixed housing 1 and is connected to the drive end 21 through the fixed housing 1, forming a complete power transmission system. When the drive end 21 moves, it can drive the driven end 22 to rotate within the fixed housing 1. The rotating assembly 3 consists of a rotating rod 31 and a multi-layer baffle assembly 32. The rotating rod 31 is rotatably connected to the drive end 21 of the drive unit 2 through a drive part 33, ensuring that the power of the drive end 21 can be smoothly transmitted to the rotating rod 31.

[0026] When the parking lock needs to be activated, the drive unit 2 starts to work. The drive end 21 generates power and drives the driven end 22 to move synchronously. Since the rotating rod 31 is connected to the driven end 22 through the drive part 33, the rotation of the drive end 21 will cause the rotating rod 31 to rotate accordingly. The multi-layer baffle assembly 32 is fixedly installed on the rotating rod 31. When the rotating rod 31 rotates, the multi-layer baffle assembly 32 will move together with the rotating rod 31. During the movement, each layer of the baffle assembly 32 will gradually slide out in sequence. As each layer of the baffle slides out, the overall height of the baffle assembly 32 will continuously increase, eventually forming a higher blocking structure, thereby effectively preventing the vehicle from driving out.

[0027] In this embodiment, the baffle assembly 32 mainly consists of three layers of baffles stacked sequentially: a first baffle 321, a second baffle 322, and a third baffle 323. These three layers of baffles form a multi-layered and flexibly sliding baffle structure through a specific sliding and connection mechanism. Specifically, the second baffle 322 can slide relative to the first baffle 321, while the third baffle 323 can further slide relative to the second baffle 322. Meanwhile, a first torsion spring 324 and a second torsion spring 325 are respectively installed on the rotating rod 31. The first torsion spring 324 is connected to the second baffle 322 and is used to control the sliding and resetting of the second baffle 322 relative to the first baffle 321. The second torsion spring 325 is connected to the third baffle 323 and is responsible for regulating the sliding and resetting of the third baffle 323 relative to the second baffle 322.

[0028] Furthermore, the first torsion spring 324 and the second torsion spring 325 are always kept in a taut state. When the rotating rod 31 starts to rotate, the first torsion spring 324 and the second torsion spring 325 release torque. As the rotation continues, the first torsion spring 324 and the second torsion spring 325 will be gradually stretched, and the corresponding second baffle 322 and the third baffle 323 will be displaced, and their height will continue to increase.

[0029] It should be noted that the initial length of the first torsion spring 324 is set to be less than the sliding distance of the second baffle 322 during the sliding process. This means that when the second baffle 322 slides to its maximum stroke, the first torsion spring 324 still has sufficient elastic margin to continue to function and will not affect the normal movement of the baffle assembly 32 due to length limitations. Similarly, the initial length of the second torsion spring 325 is less than the total sliding distance of the second baffle 322 and the third baffle 323 during the sliding process. This ensures that the second torsion spring 325 can always maintain effective elastic tension during the entire movement of the baffle assembly 32, providing stable power support for the height change of the baffle assembly 32.

[0030] Specifically, a groove 4 is provided in the middle of the first baffle 321 to provide installation space for the first torsion spring 324 and the second torsion spring 325. When the baffle assembly 32 is not moving, the projection of the second baffle 322 and the third baffle 323 onto the first baffle 321 is completely within the first baffle 321, so that the baffle assembly 32 can withstand greater pressure, has higher durability, and is not easily damaged.

[0031] To facilitate better control of the rotation of the baffle assembly 32, the drive unit 33 includes a slide plate 331, a connecting rod 332, and a push rod 333. The slide plate 331 is rotatably connected to the driven end 22 and can move along the driven end 22. The driven end 22 is a lead screw, and the slide plate 331 is rotatably connected to the lead screw. As the lead screw rotates, the slide plate 331 moves linearly along the lead screw. One end of the push rod 333 is fixed to the rotating rod 31. The two ends of the connecting rod 332 are respectively connected to the other end of the push rod 333 and the slide plate 331 by rotation. When the slide plate 331 moves along the driven end 22, the push rod 333 rotates under the linkage of the connecting rod 332, and the rotation direction of the push rod 333 is opposite to the rotation direction of the connecting rod 332 relative to the slide plate 331. During the movement, the relative movement between the components is smoother, reducing movement interference and friction, avoiding component jamming or damage caused by unreasonable movement direction, and improving the movement efficiency and reliability of the device.

[0032] When the parking lock is not in operation, the baffle assembly 32 is tilted downwards. At the same time, the push rod 333 and the connecting rod 332 are on the same straight line. If pressure is applied to the baffle assembly 32 during the driving or parking process, the structure formed by the push rod 333 and the connecting rod 332 being on the same straight line can withstand the pressure more effectively, thus having better rigidity and stability when dealing with pressure.
