Description

Technical Field

[0001] This application relates to the field of automated parking system technology, and in particular to a wheel stop mechanism. Background Technology

[0002] Existing automated parking systems typically consist of a parking bay and a multi-level parking garage. During parking, the driver parks the vehicle on the parking platform in the bay and then leaves, allowing a transporter to move the vehicle into the garage. The parking bay usually contains photoelectric detection or tire alignment mechanisms to ensure the vehicle is aligned correctly. This ensures that after the vehicle reaches the parking platform, the front wheels are positioned in the correct length direction, and the vehicle's height and parking position meet requirements for subsequent positioning and transport by the transporter. However, in this system, the driver can only confirm parking accuracy via a display screen, requiring multiple adjustments to the vehicle's position. Furthermore, there is a risk of mistaking the accelerator for the brake, resulting in collisions with walls or doors, or even crashing into the garage, posing significant safety hazards.

[0003] To address the aforementioned issues, a wheel stop mechanism needs to be installed in the parking compartment to mechanically block the vehicle's front wheels and prevent the aforementioned safety hazards during parking. In existing technologies, wheel stop mechanisms are typically installed on the surface of the parking position. When it is necessary to stop the wheels during parking, the mechanism rises to prevent wheel movement. However, since parking platforms are usually chain plates, steel frames, or concrete floors, it is impossible to directly install a liftable wheel stop mechanism, or direct installation at the parking position would interfere with the parking platform components. Therefore, existing wheel stop mechanisms cannot meet the vehicle stopping requirements of a contactless, center-aligned parking compartment. Utility Model Content

[0004] Therefore, it is necessary to provide a wheel stop mechanism applicable to non-contact centering parking compartments.

[0005] A wheel stop mechanism is provided for a multi-level parking garage, the multi-level parking garage having a parking compartment with a parking platform inside, allowing vehicles to drive from the parking compartment and park on the parking platform; the wheel stop mechanism is disposed on the side of the parking platform, and the wheel stop mechanism includes:

[0006] The gear lever has a stop state and a retracted state; when in the stop state, the gear lever is at least partially located within the area of ​​the parking platform to stop the wheels in the direction of vehicle travel; when in the retracted state, the gear lever leaves the area of ​​the parking platform to release the wheels from the stop in the direction of vehicle travel.

[0007] A drive assembly, connected to the shift lever, is used to drive the shift lever to switch between a stopped state and a retracted state.

[0008] In one embodiment, the drive assembly includes a rotating component, a driving component, and a transmission component. The stop lever is connected to the rotating component, and the transmission component drives the driving component and the rotating component. The rotating component can drive the stop lever to swing around the axis of the rotating component to switch between a stop state and a retracted state.

[0009] In one embodiment, the rotating component is a worm gear, and the transmission component is a worm; the driving component is connected to the transmission component and is used to drive the transmission component to rotate, and the rotating component is meshed with the transmission component.

[0010] In one embodiment, the stop lever includes a rod body and a connecting portion. In the horizontal direction, the rod body is located on the side of the rotating member, and the connecting portion extends to the position of the rotating member and is connected to the rotating member through the connecting portion.

[0011] In one embodiment, the wheel stop mechanism further includes a housing, in which the rotating member and the transmission member are disposed; the housing has an opening, and the rotating member extends at least partially from the opening out of the housing to connect with the stop lever.

[0012] In one embodiment, the wheel stop mechanism further includes a support frame, and the housing and the drive member are respectively fixed on the support frame; the end of the transmission member near the drive member is connected to the output shaft of the drive member through a coupling.

[0013] In one embodiment, the wheel stop mechanism further includes a first limiting member and a second limiting member, which are electrically connected to the drive assembly respectively; when the stop lever is in the stop state, the stop lever can abut against the first limiting member; when the stop lever is in the retracted state, the stop lever can abut against the second limiting member.

[0014] In one embodiment, the first limiting member and the second limiting member are located on the same horizontal plane along the horizontal direction; the first limiting member and the second limiting member are distributed front to back along the length direction of the parking platform, and the stop lever is located between the first limiting member and the second limiting member.

[0015] In one embodiment, the parking compartment is provided with a side step, which is located on the side of the parking platform along the width direction of the parking platform; the side step is covered on the wheel stop mechanism, and when the stop lever is in the stop state, the stop lever part extends out of the side step; when the stop lever is in the retracted state, the stop lever retracts into the side step.

[0016] Compared with the prior art, the wheel stop mechanism is set on the side of the parking platform. It stops the wheels in the parking platform by changing the position of the stop lever. It does not need to be installed on the bottom or platform of the parking platform, and there will be no interference with the chain plate, steel frame, etc. It also reduces the overall installation difficulty and makes installation simple.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figures 1 to 5This application provides a wheel stop mechanism for use in a multi-level parking garage. The multi-level parking garage has a parking compartment with a parking platform 100 inside, allowing vehicles to drive from the parking compartment entrance and park on the parking platform 100. The wheel stop mechanism is located on the side of the parking platform 100. The wheel stop mechanism includes a lever 1 and a drive assembly 2. The lever 1 has a stopped state and a retracted state. In the stopped state, the lever 1 is at least partially located within the area of ​​the parking platform 100 to stop the wheels in the vehicle's travel direction. In the retracted state, the lever 1 moves away from the area of ​​the parking platform 100 to release the wheels in the vehicle's travel direction. The drive assembly 2 is connected to the lever 1 and is used to drive the lever 1 to switch between the stopped state and the retracted state.

[0030] Understandably, before the vehicle drives from the parking bay entrance to the parking platform 100, the drive unit 22 drives the gear lever 1 from the retracted state to the stop state, with the gear lever 1 partially located within the area of ​​the parking platform 100. When the vehicle reaches the parking platform 100, the front wheels contact the gear lever 1, allowing the driver to park the vehicle accurately without multiple adjustments. If the driver mistakenly operates the gear lever and the vehicle lurches forward, the gear lever 1 may also prevent the vehicle from crashing into the wall or the parking space, thus minimizing the risk of an accident.

[0031] The wheel stop mechanism is located on the side, with the stop lever 1 extending from the side towards the parking platform 100, rather than rising from the bottom of the parking platform 100. This avoids interference with the chain plate, steel frame, concrete, or other components of the parking platform 100, and ensures good compatibility with non-centering parking cabs. Furthermore, the installation difficulty of the wheel stop mechanism is greatly reduced, and the structure is simpler.

[0032] In one embodiment, the drive assembly 2 includes a rotating member 21, a driving member 22, and a transmission member 23. The stop lever 1 is connected to the rotating member 21, and the transmission member 23 drives the driving member 22 and the rotating member 21. The rotating member 21 can drive the stop lever 1 to swing around the axis of the rotating member 21 to switch between the stop state and the retracted state.

[0033] Understandably, by using the rotating component 21 to rotate and drive the lever 1 to swing, compared to the linear extension and retraction of the lever 1, the lever 1 occupies less space, the wheel stop mechanism has less stringent requirements on the size of the installation position, and is more adaptable.

[0034] For example, the rotating member 21 rotates horizontally, and the lever 1 also swings horizontally. When the lever 1 is in the stop position, it swings to extend along the width direction of the parking platform 100, thus isolating the parking platform 100. When the lever 1 is in the retracted position, it swings to extend along the length direction of the parking platform 100 (i.e., the vehicle's driving direction). To accommodate vehicles, the parking platform 100 is typically long in the length direction. The retracted lever 1 extends along the length direction of the parking platform 100, resulting in a more spacious overall installation and higher adaptability.

[0035] Furthermore, the rotating component 21 is a worm gear. The transmission component 23 is a worm. The driving component 22 is connected to the transmission component 23 and is used to drive the transmission component 23 to rotate. The rotating component 21 is meshed with the transmission component 23.

[0036] For example, the drive component 22 is an electric motor. When the drive component 22 starts, it drives the transmission component 23 to rotate. The transmission component 23 meshes with the rotating component 21 to rotate, and the rotating component 21 drives the lever 1 to swing. The worm gear transmission has a high reduction ratio, and the motor can keep the vehicle moving forward with only a small braking torque.

[0037] In one embodiment, the stop lever 1 includes a lever body 11 and a connecting portion 12. Horizontally, the lever body 11 is located on the side of the rotating member 21, and the connecting portion 12 extends to the position of the rotating member 21 and is connected to the rotating member 21 via a connecting member 13. This makes installation and disassembly more convenient.

[0038] For example, the connecting part 12 can be a fan-shaped or ring-shaped structure for better connection with the rotating part 21. The rod body 11 is a hollow square tube, which is simple and lightweight. The rod body 11 and the connecting part 12 can be welded together or directly integrally formed.

[0039] For example, the connector 13 may be a bolt, screw, rivet, etc., avoiding the axial position of the rotating part 21, to connect the connector 12 and the rotating part 21 together.

[0040] In one embodiment, the wheel stop mechanism further includes a housing 3. A rotating member 21 and a transmission member 23 are disposed inside the housing 3. An opening 31 is provided on the housing 3, and the rotating member 21 extends at least partially out of the housing 3 through the opening 31 to connect with the stop lever 1.

[0041] Understandably, the entire assembly is integrated into the housing 3, and installation only requires fixing the housing 3 in place, making the assembly operation simple and labor-saving.

[0042] For example, the transmission member 23 is located on the side of the housing 3 away from the opening 31, and the two ends of the transmission member 23 are respectively inserted into the side wall of the housing 3 and can rotate relative to the housing 3.

[0043] For example, the rotating component 21 is placed horizontally inside the housing 3. A rotating shaft 211 is located at the center of the rotating component 21, with both ends of the shaft passing through the upper and lower inner walls of the housing 3, respectively, and capable of rotating relative to the housing 3. One side of the rotating component 21 engages with the transmission component 23, and the other side extends out of the housing 3 through the opening 31. The connecting part 12 is connected to the position where the rotating component 21 extends out of the housing 3.

[0044] In one embodiment, the wheel stop mechanism further includes a support frame 4. The housing 3 and the drive member 22 are respectively fixed on the support frame 4. The end of the transmission member 23 near the drive member 22 is connected to the output shaft of the drive member 22 via a coupling 5.

[0045] For example, coupling 5 is a coupling.

[0046] In one embodiment, the wheel stop mechanism further includes a first limiting member 61 and a second limiting member 62. The first limiting member 61 and the second limiting member 62 are electrically connected to the drive assembly 2, respectively. When the stop lever 1 is in the stop state, the stop lever 1 can abut against the first limiting member 61. When the stop lever 1 is in the retracted state, the stop lever 1 can abut against the second limiting member 62.

[0047] Understandably, the first limiting member 61, the second limiting member 62, and the drive assembly 2 are all electrically connected to the control system of the parking compartment. When the gear lever 1 abuts against the first limiting member 61 or the second limiting member 62, the first limiting member 61 or the second limiting member 62 can feed back a signal to the control system, which then controls the drive member 22 in the drive assembly 2 to stop, and the gear lever 1 stops swinging and remains in its current position. Through the setting of the first limiting member 61 and the second limiting member 62, the position of the gear lever 1 is accurately positioned.

[0048] For example, the first limit element 61 is a sensor or a limit switch. The second limit element 62 is a sensor or a limit switch. The control system is a PLC or a microcontroller. The specific principles, signal feedback, and control logic of the above electrical components are existing technologies and will not be described in detail.

[0049] Furthermore, along the horizontal direction, the first limiting member 61 and the second limiting member 62 are located on the same horizontal plane. Along the length of the parking platform 100, the first limiting member 61 and the second limiting member 62 are distributed front to back, with the gear lever 1 located between the first limiting member 61 and the second limiting member 62. This better accommodates the swinging of the gear lever 1 and ensures accurate positioning.

[0050] In one embodiment, the parking compartment is provided with a side step 200. The side step 200 is located on the side of the parking platform 100 along its width. The side step 200 covers the wheel stop mechanism; when the stop lever 1 is in the stop state, a portion of the stop lever 1 extends out of the side step 200. When the stop lever 1 is in the retracted state, the stop lever 1 retracts into the side step 200.

[0051] Understandably, the wheel stop mechanism is concealed inside the side pedal 200 and rotates out from inside the side pedal 200, without interfering with the non-contact centering steel frame structure, etc. When the stop lever 1 is retracted, it is completely retracted into the side pedal 200, flush with the edge of the side pedal 200, without occupying extra space, and the overall appearance is aesthetically pleasing.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
