Description

Technical Field

[0001] This utility model relates to the field of automatic parking equipment, specifically to a three-dimensional parking retrieval device and its friction drive mechanism. Background Technology

[0002] In mechanical automated parking systems, friction wheel retrieval devices use friction wheels to drive friction plates on a vehicle-carrying platform. This friction force moves the platform, allowing for vehicle storage and retrieval. This system is widely popular because it does not damage tires during vehicle storage and retrieval and minimizes vehicle sway.

[0003] However, in existing technologies, friction wheels are mostly fixed, making it impossible to adjust their position. When the vehicle platform vibrates or deforms, it is prone to jamming or getting stuck. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a three-dimensional vehicle storage and retrieval device and its friction drive mechanism.

[0005] According to the present invention, a friction drive mechanism includes a base, a first drive motor, and an active friction wheel;

[0006] The base includes a base plate, a rotating plate, and an elastic element. Two rotating plates are rotatably connected to the base plate in a side-by-side, spaced manner. The upper surfaces of the outer ends of the two rotating plates on the same side are respectively rotatably connected to the active friction wheel. The active friction wheels on the two rotating plates are arranged side by side. Each rotating plate is connected to the first drive motor, and the first drive motor drives the active friction wheel.

[0007] The two ends of the elastic element are respectively connected to the inner ends of the two rotating plates on the same side. The elastic element drives the two rotating plates to rotate so that the gap between the two sets of active friction wheels is smaller than the thickness of the plate to be clamped.

[0008] In some embodiments, a driven friction wheel is rotatably connected to the rotating plate. The driven friction wheel is located between the driving friction wheel and the elastic element. The driven friction wheels on the two rotating plates are arranged side by side, and a gap is provided between the side by side driven friction wheels for clamping the plate to be clamped.

[0009] In some embodiments, the driven friction wheel is rotatably connected above the moving connection point between the rotating plate and the base plate.

[0010] In some embodiments, the active friction wheel and / or the driven friction wheel are made of rubber or resin.

[0011] In some embodiments, the elastic element is a spring, an elastic rubber column, or an elastic telescopic rod.

[0012] In some embodiments, the rotating plate has a notch at one end relative to the active friction wheel, and a connecting post is provided within the notch. The two ends of the elastic element are sleeved on the two oppositely arranged connecting posts.

[0013] This utility model also provides a three-dimensional vehicle storage retrieval device, which adopts the aforementioned friction drive mechanism and further includes a fixed frame and a second drive motor;

[0014] The fixed frame is a rectangular structure frame, and the friction drive mechanism is slidably connected to the two longitudinal beams of the fixed frame through the base plate. The second drive motor drives the base plate to move linearly.

[0015] In some embodiments, two sets of friction drive mechanisms are slidably connected on the two longitudinal beams, and the two sets of friction drive mechanisms are connected to the two substrates through a connecting beam. The second drive motor drives the two sets of substrates to move synchronously.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The friction drive mechanism provided by this utility model places two sets of active friction wheels on a rotating plate arranged side by side. The two sets of active friction wheels are brought closer to each other to a predetermined distance by an elastic element. Since the two rotating plates can rotate to one side at a certain angle, even if there is a deviation between the center position line of the two sets of active friction wheels and the axis of the pull plate located on the lower surface of the vehicle platform, the pull plate can still be moved between the two sets of active friction wheels by rotating the two rotating plates to one side at a predetermined angle. The structure is simple and the operation is convenient. It solves the technical problem in the prior art that the pull plate is difficult to enter between the friction wheels when it is not in a centered position, which leads to the inability to transfer the vehicle platform. It effectively improves the efficiency of vehicle platform entry and exit from the garage, while avoiding collision damage caused by misalignment, and improves the safety factor of vehicle platform entry and exit from the garage.

[0018] 2. The friction drive mechanism provided by this utility model improves the efficiency and safety of lateral movement of the vehicle platform by adding a driven friction wheel to the drive friction mechanism. Attached Figure Description

[0024] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention. Example

[0025] This embodiment provides a friction drive mechanism, referring to... Figure 1-2 As shown, the system mainly includes a base 1, a first drive motor 2, and an active friction wheel 3. The base 1 includes a base plate 11, a rotating plate 12, and an elastic element 13. The base plate 11 serves as a carrier, and its plate structure can be rectangular, circular, or irregular in shape. Two rotating plates 12 are rotatably connected to the base plate 11 in a parallel manner and at a predetermined distance from each other. The rotatable connection between the rotating plate 12 and the base plate 11 is at the middle position of the rotating plate 12. Preferably, a shaft hole is provided at the middle position of the rotating plate 12, and a rotating shaft adapted to the shaft hole of the rotating plate 12 is detachably connected to the base plate 11. The two rotating plates 12 rotatably connected to the base plate 11 are arranged side by side and can both rotate. The two ends of the elastic element 13 are respectively connected to the inner ends of the two rotating plates 12 on the same side, and the elastic element 13 is in a compressed state. The compressed elastic element 13 can drive the two rotating plates 12 to rotate relative to each other around the rotating shaft, thereby bringing the outer ends of the two rotating plates 12 on the same side closer together. As needed, the gap between the two rotating plates 12 and / or the deformation of the elastic element 13 can be adjusted to bring the outer ends of the two rotating plates 12 on the same side closer to each other to a predetermined distance. The elastic element 13 can be a spring, an elastic rubber column, or an elastic telescopic rod, and the elastic telescopic rod can be a hydraulic or pneumatic telescopic rod. (Refer to...) Figure 1As shown, this embodiment provides a connection method between the elastic element 13 and the rotating plate 12. A notch 121 is formed at one end of the rotating plate 12 where it connects to the elastic element 13. The notch 121 serves two purposes: firstly, to accommodate the elastic element 13, and secondly, to reduce the weight of the rotating plate 12 and increase the elastic force driving the elastic element 13 onto the two sets of rotating plates 12. A connecting post 122 is formed on the side of the notch 121, and the structural shape of the connecting post 122 is adapted to the structural shape of the elastic element 13. For example, in this embodiment, the elastic element 13 is selected as a cylindrical compression spring, and the connecting post 122 is also a cylindrical structure. The connecting post 122 is a solid structure or has an internal cavity, and both ends of the elastic element 13 can be sleeved on the outside of the connecting post 122 or sleeved within the cavity of the connecting post 122. The sleeved structure of the elastic element 13 and the connecting post 122 has the advantages of simple structure, convenient disassembly, and low cost. When the elastic element 13 is an elastic rubber column or an elastic telescopic rod, the above connection structure can also be applied. In the above description, the so-called same-side outer end and same-side inner end of the rotating plate 12 refer to the ends determined according to the entry direction of the vehicle plate. That is, the same-side outer end is the end where the vehicle plate initially enters, while the same-side inner end is the other end relative to the same-side outer end.

[0026] Two rotating plates 12 are rotatably connected to a set of active friction wheels 3 on their outer surfaces on the same side. The active friction wheels 3 and the elastic element 13 are located at opposite ends of the rotating plates 12, and the rotatable connection point between the rotating plates 12 and the base plate 11 is located between the elastic element 13 and the active friction wheels 3. The outer circumferential surfaces of the two sets of active friction wheels 3 are either in contact with each other or have a predetermined gap between them under the elastic action of the elastic element 13. This predetermined gap is smaller than the thickness of the traction plate located on the lower surface of the vehicle platform to be clamped, thus achieving the effect of clamping the traction plate with the two sets of active friction wheels 3 and driving the vehicle platform to move laterally through friction. The active friction wheels 3 are made of rubber or resin. A set of first drive motors 2 are fastened to the lower surfaces of the two rotating plates 12 on the same side. The first drive motors 2 drive the active friction wheels 3 respectively. Two sets of first drive motors 2 drive two sets of active friction wheels 3 to rotate in opposite directions, thereby driving the vehicle platform out of or into the warehouse through the frictional driving force formed with the traction plate located on the lower surface of the vehicle platform.

[0027] The working principle of the friction drive device provided in this embodiment is explained using the removal of the vehicle platform as an example: After the base 1, which is equipped with the first drive motor 2 and the active friction wheel 3, rises or falls to a predetermined position with the transport trolley, the base 1 is driven to move laterally a predetermined distance in the direction of the vehicle platform. The end of the traction plate located on the lower surface of the vehicle platform is squeezed between the two sets of active friction wheels 3. At this time, the traction plate squeezes between the two sets of active friction wheels 3, causing the outer ends of the two rotating plates 12 on the same side to move away from each other, while the inner ends on the same side to move closer to each other. That is, the elastic element 13 is further compressed. Then, the elastic reaction force generated by the compression of the elastic element 13 causes the traction plate to be clamped by the two sets of active friction wheels 3. The two sets of first drive motors 2 drive the two sets of active friction wheels 3 to rotate synchronously in opposite directions. The vehicle platform is removed by the friction between the two sets of active friction wheels 3 and the traction plate.

[0028] The friction drive mechanism provided in this embodiment places two sets of active friction wheels on a rotating plate arranged side by side. An elastic element brings the two sets of active friction wheels closer to each other to a predetermined distance. Since the two rotating plates can rotate to one side at a certain angle, even if there is a deviation between the center line of the two sets of active friction wheels and the axis of the pull plate located on the lower surface of the vehicle platform, the pull plate can still be moved between the two sets of active friction wheels by rotating the two rotating plates to one side at a predetermined angle. The structure is simple and the operation is convenient. It solves the technical problem in the prior art that the pull plate is difficult to enter between the friction wheels when it is not in a centered position, which makes it impossible to transfer the vehicle platform. It effectively improves the efficiency of vehicle platform entry and exit from the garage, while avoiding collision damage caused by misalignment, and improves the safety factor of vehicle platform entry and exit from the garage. Example

[0029] This embodiment 2 is based on embodiment 1, and improves the efficiency and safety of lateral movement of the vehicle platform by adding a driven friction wheel to the driving friction mechanism. Specifically:

[0030] Reference Figure 1-2 As shown, a driven friction wheel 4 is rotatably connected to the rotating plate 12. The rotatable connection position of the driven friction wheel 4 is located between the driving friction wheel 3 and the elastic element 13. Two sets of driven friction wheels 4 on the two rotating plates 2 are arranged side by side, and the gap between the two sets of driven friction wheels 4 is smaller than the thickness of the traction plate below the vehicle platform, so as to achieve the purpose of clamping the traction plate. The driving friction wheel 3 and the driven friction wheel 4 on the same rotating plate 12 are arranged coaxially. By adding driven friction wheels 4, after the driving friction wheel 3 clamps and drives the vehicle platform forward a predetermined distance, the traction plate enters between the two sets of driven friction wheels 4. The two sets of driven friction wheels 4 further increase the clamping force on the traction plate, reduce the risk of slippage between the driving friction wheel 3 and the traction plate, and improve the efficiency and safety of the lateral movement of the vehicle platform.

[0031] Furthermore, the rotational connection point of the driven friction wheel 4 is above the dynamic connection point between the rotating plate 12 and the base plate 11. The rotating shaft connected to the base plate 11 is higher than the surface of the rotating plate 12, and the driven friction wheel 4 is rotatably connected to the rotating shaft and located above the rotating plate 12. At this time, the driven friction wheel 4 does not rotate with the rotation of the rotating plate 12, and the gap between the two sets of driven friction wheels 4 can be fixed. The structure is simple and the operation is convenient. Example

[0032] This embodiment 3 is a three-dimensional garage vehicle platform storage and retrieval device formed on the basis of embodiment 1 or embodiment 2. It adopts the friction drive mechanism described in embodiment 1 and also includes a fixed frame 5 and a second drive motor 6.

[0033] Reference Figure 1-4 As shown, the fixing frame 5 is mainly a rectangular frame structure formed by two longitudinal beams 51 and a crossbeam 52 connecting and fixing the two longitudinal beams 51. The crossbeam 52 is located on the lower surface of the two longitudinal beams 51, and the upper surface of the two longitudinal beams 51 is provided with slide rails. The base plate 11 of the friction drive mechanism is slidably connected to the slide rails on the two longitudinal beams 51. The base plate 11 is driven by the drive shaft of the second drive motor 6, thereby driving the friction drive mechanism to move linearly, so that the active friction wheel 3 is clamped and connected to the traction plate located on the lower surface of the vehicle platform.

[0034] Furthermore, two sets of friction drive mechanisms are slidably connected to the two longitudinal beams 51. These two sets of friction drive mechanisms are slidably connected to both ends of the two longitudinal beams 51 via base plates 11, and the two base plates 11 are connected by a connecting beam 7. Thus, a second drive motor 6 can drive the two sets of module drive mechanisms to move synchronously, achieving the goal of cost reduction. When two sets of friction drive mechanisms are installed on the two longitudinal beams 51, entry and exit from the automated parking garage on both sides can be achieved, improving operational efficiency.
