Description

Technical Field

[0001] This invention relates to the field of garage technology, and in particular to a vertical circulation garage. Background Technology

[0002] Related technologies indicate that most vertical circulation equipment on the market currently uses shift fork transmission, which has problems such as high noise, high demand for reducer output torque, large axial and radial forces, and small gap between the shift fork and the lower inner guide rail, which can easily cause interference. The existing toothed chain pin transmission scheme, although smooth and quiet, is limited to 12mm-16mm in thickness due to the limited thickness of the toothed chain. When applied to vertical circulation garages with 11 or more floors, the contact area between the chain teeth and the outer sleeve of the pin wheel is limited, resulting in excessive surface contact stress. This places high demands on the strength of the pin and sleeve materials, and the parts are prone to wear, which limits the design of higher-rise vertical circulation garages. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art.

Detailed Implementation

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following is for reference. Figures 1-18 A vertical circulation parking garage 1000 according to an embodiment of the present invention is described.

[0020] like Figures 1-18 As shown, a vertical circulation parking garage 1000 according to an embodiment of the present invention includes: a transmission system 100 and a parking platform assembly 200, wherein the transmission system 100 includes: a frame 6, a transmission chain 2, a first transmission wheel 3, a slewing bearing 4 and a connecting plate 5.

[0021] Specifically, a guide rail 1 is formed on the frame 6, and a transmission chain 2 is disposed in the guide rail 1. The transmission chain 2 includes multiple chain links 21 connected end to end. Each chain link 21 has a chain groove 22. The chain groove 22 includes a first groove and a second groove. A second groove is arranged between every two adjacent first grooves. The first transmission wheel 3 includes a first wheel body 31 and multiple first wheel teeth 32 arranged along the circumferential direction of the first wheel body 31. The first wheel teeth 32 include a first tooth 321 and a second tooth 322. The first tooth 321 is arranged corresponding to the first groove, and the second tooth 322 is arranged corresponding to the second groove. A slewing support is disposed on the frame 6 and the slewing support 4 is spaced apart from the first transmission wheel 3. A second transmission wheel 41 is disposed on the slewing support 4. The transmission chain 2 is wound between the first transmission wheel 3 and the second transmission wheel 41. The connecting plate 5 is connected to the chain link 21, and the parking plate assembly 200 is hinged to the connecting plate 5.

[0022] It is understandable that the transmission system 100, in conjunction with the parking platform assembly 200, achieves efficient, stable, and safe vehicle storage and retrieval functions, with high space utilization, low failure rate, and low maintenance cost. A guide rail 1 is formed on the frame 6, and the transmission chain 2 is located within the guide rail 1. The guide rail 1 guides the movement path of the transmission chain 2, ensuring that it moves according to a preset direction and trajectory. The transmission chain 2 is composed of multiple chain links 21 connected end-to-end. Each chain link 21 has a chain groove 22, which includes a first groove and a second groove. A second groove is provided between two adjacent first grooves. The transmission wheel 3 includes a first wheel body 31 and a plurality of first gear teeth 32 arranged along its circumferential direction. The first gear teeth 32 include a first tooth 321 corresponding to a first groove and a second tooth 322 corresponding to a second groove, such that the first tooth 321 and the second tooth 322 respectively mesh with the first groove and the second groove. This allows the transmission chain 2 and the first transmission wheel 3 to form a relatively continuous and uniform meshing contact, which is beneficial to improving the stability and reliability of the transmission between the first transmission wheel 3 and the transmission chain 2, avoiding stress concentration problems caused by a single meshing structure, improving transmission efficiency, and also helping to extend the service life of the transmission chain 2 and the first transmission wheel 3.

[0023] Furthermore, by providing a slewing bearing 4 spaced apart from the first transmission wheel 3, and with a second transmission wheel 41 mounted on the slewing bearing 4, the transmission chain 2 is wound between the first transmission wheel 3 and the second transmission wheel 41. The slewing bearing 4 provides stable support for the movement of the transmission chain 2, and also reduces friction and the possibility of vibration during the movement of the transmission chain 2, thus enhancing its stability. Additionally, by providing the slewing bearing 4 along the movement path of the transmission chain 2, the tension of the transmission chain 2 can be easily adjusted, further improving its stability during long-term operation.

[0024] For example, the slewing bearing 4 and the first transmission wheel 3 are spaced apart in a preset direction. For example, the slewing bearing 4 and the first transmission wheel 3 can be spaced apart in the vertical direction, with the slewing bearing 4 located above the first transmission wheel 3. By providing the slewing bearing 4 and the first transmission wheel 3 on the movement path of the transmission chain 2, the slewing bearing 4 can reduce the lifting friction of the transmission chain 2, making the movement of the transmission chain 2 more stable, and can also reduce the noise generated when the transmission chain 2 moves.

[0025] For example, compared to shift fork drives, shift fork drives have a small gap between the shift fork and the lower guide rail 1 during engagement, which is prone to interference and results in greater impact and higher operating noise during driving. By setting alternating first and second grooves on the transmission chain 2 and correspondingly meshing with the first tooth 321 and the second tooth 322 of the first transmission wheel 3, continuous rolling engagement between the transmission chain 2 and the first transmission wheel 3 is achieved, avoiding the problem of interference between the shift fork insertion force and the guide rail, reducing noise, and making the operation of the transmission chain 2 smoother.

[0026] According to an embodiment of the present invention, the vertical circulation garage 1000 improves the stability and reliability of the meshing between the first transmission wheel 3 and the transmission chain 2 through the correspondence between the double grooves and double teeth. The slewing bearing 4 supports the movement of the transmission chain 2, reduces the friction of the transmission chain 2 during movement, and reduces the noise generated by the transmission chain 2 during movement. This effectively improves the overall operational stability and reliability of the transmission system 100. Through the cooperation between the transmission system 100 and the parking plate assembly 200, efficient, stable, and safe vehicle storage and retrieval functions are achieved, with high space utilization, low failure rate, and low maintenance cost.

[0027] Reference Figure 1 and Figure 17According to some embodiments of the present invention, multiple connecting plates 5 are arranged at intervals, and multiple parking platform assemblies 200 are also included, with each parking platform assembly 200 corresponding to one of the multiple connecting plates 5. By evenly spacing the multiple connecting plates 5, the weight of the corresponding parking platform assembly 200 and the vehicle weight are distributed to multiple chain links 21, avoiding load concentration on a few nodes. This ensures balanced force on the transmission chain 2, reduces fatigue damage to the transmission chain 2, and extends its service life. The one-to-one correspondence between the multiple parking platform assemblies 200 and the multiple connecting plates 5 forms a modular design. If a parking platform malfunctions or requires maintenance, it can be disassembled and replaced individually without affecting the normal operation of the remaining parking platform assemblies 200. This also ensures operational synchronization and improves vehicle parking safety.

[0028] Reference Figure 7 , Figure 11 and Figure 12 According to some embodiments of the present invention, each link 21 is provided with a roller 211 at both ends, and two pins 212 are provided between every two adjacent rollers 211. A tooth gap is formed between two adjacent first gear teeth 32 on the first transmission wheel 3. The tooth gap includes a first tooth gap 323 and a second tooth gap 324. Two second tooth gaps 324 are arranged between every two adjacent first tooth gaps 323. The rollers 211 are correspondingly arranged with the first tooth gaps 323, and the pins 212 are correspondingly arranged with the second tooth gaps 324.

[0029] By providing a roller 211 at both ends of each link 21, and having the roller 211 corresponding to the first tooth interval 323, the rollers 211 at both ends of the link 21 can form rolling contact with the first tooth interval 323. This reduces the frictional resistance between the first drive wheel 3 and the link 21, making the relative movement between the first drive wheel 3 and the drive chain 2 smoother, and also reducing the wear caused by friction between the first drive wheel 3 and the link 21.

[0030] Furthermore, by setting two pins 212 between each pair of adjacent rollers 211 and arranging two second tooth gaps 324 between each pair of adjacent first tooth gaps 323, the number of pins 212 and second tooth gaps 324 can be the same and correspond one-to-one. The pins 212 can bear the load borne by the transmission chain 2 to a certain extent, so that the stress is distributed more evenly, reducing the possibility of the transmission chain 2 breaking due to local stress concentration, thereby extending the service life of the transmission chain 2 and improving the safety and reliability of the transmission chain 2 during operation.

[0031] In some embodiments, the link 21 includes an inner link plate 213 and an outer link plate 214. For example, the inner link plate 213 is used to connect the roller 211 and the pin 212 within the same link 21, and the outer link plate 214 is used to connect adjacent links 21. The inner link plate 213 and the outer link plate 214 are arranged in parallel and the inner link plate 213 is located inside the outer link plate 214. They can jointly bear the load of the transmission chain 2, avoid overload of a single plate, and especially during the lifting process of the transmission chain 2, they can effectively resist the deformation of the transmission chain 2 caused by stretching, which is beneficial to enhance the overall structural strength of the transmission chain 2.

[0032] For example, a bushing is provided on the pin 212, so that the friction between the inner chain plate 213 and the pin 212 is concentrated on the surface of the bushing, which can reduce the wear caused by direct friction between the inner chain plate 213 and the pin 212.

[0033] Reference Figures 8-10 According to some embodiments of the present invention, the second transmission wheel 41 includes a second wheel body 411 and a plurality of second wheel teeth 412 arranged in the circumferential direction of the second wheel body 411. The second wheel teeth 412 include a third tooth 4121 and a fourth tooth 4122. The third tooth 4121 is correspondingly disposed with the first groove, and the fourth tooth 4122 is correspondingly disposed with the second groove.

[0034] Each link 21 has a chain groove 22, which includes a first groove and a second groove. A second groove is provided between two adjacent first grooves. The second drive wheel 41 includes a second wheel body 411 and a plurality of second gear teeth 412 arranged along the circumferential direction of the second wheel body 411. The second gear teeth 412 include a third tooth 4121 and a fourth tooth 4122, such that the third tooth 4121 and the fourth tooth 4122 respectively mesh with the first groove and the second groove. This allows the drive chain 2 and the second drive wheel 41 to form a relatively continuous and uniform meshing contact, which is beneficial to improving the stability and reliability of the transmission between the second drive wheel 41 and the drive chain 2, avoiding stress concentration problems caused by a single meshing structure, improving transmission efficiency, and also helping to extend the service life of the drive chain 2 and the second drive wheel 41.

[0035] Reference Figures 8-10 According to some embodiments of the present invention, a tooth gap is formed between two adjacent second gear teeth 412 on the second transmission wheel 41. The tooth gap includes a third tooth gap 413 and a fourth tooth gap 414. Two fourth tooth gaps 414 are arranged between each two adjacent third tooth gaps 413. The roller 211 is correspondingly arranged with the third tooth gap 413, and the pin 212 is correspondingly arranged with the fourth tooth gap 414.

[0036] By providing a roller 211 at both ends of each link 21, and having the roller 211 corresponding to the third tooth interval 413, the rollers 211 at both ends of the link 21 can form rolling contact with the third tooth interval 413. This reduces the frictional resistance between the second drive wheel 41 and the link 21, making the relative movement between the second drive wheel 41 and the drive chain 2 smoother, and also reducing the wear caused by friction between the second drive wheel 41 and the link 21.

[0037] Furthermore, by setting two pins 212 between every two adjacent rollers 211 and arranging two fourth tooth intervals 414 between every two adjacent third tooth intervals 413, the number of pins 212 and fourth tooth intervals 414 can be the same and correspond one-to-one. The pins 212 can bear the load borne by the transmission chain 2 to a certain extent, so that the stress is distributed more evenly, reducing the possibility of the transmission chain 2 breaking due to local stress concentration, thereby extending the service life of the transmission chain 2 and improving the safety and reliability of the transmission chain 2 during operation.

[0038] Reference Figures 8-10 According to some embodiments of the present invention, the distance of the first tooth interval 323 is greater than the distance of the second tooth interval 324. Since the first tooth interval 323 is correspondingly arranged with respect to the roller 211, a sufficiently large first tooth interval 323 can ensure that the roller 211 is smoothly and without jamming when it is inserted into the first tooth interval 323, allowing the roller 211 to roll smoothly around its own axis, avoiding the roller 211 from jamming and being unable to rotate due to the distance of the first tooth interval 323 being too small. Since the second tooth interval 324 is correspondingly arranged with respect to the pin 212, the smaller distance of the second tooth interval 324 allows the pin 212 to form a tighter fit with the second tooth interval 324, which can reduce the gap loss caused by the excessive gap between the pin 212 and the second tooth interval 324, so that power can be directly and more efficiently transmitted to the pin 212 through the second tooth interval 324, thereby improving the efficiency of power transmission between the first drive wheel 3 and the chain link 21.

[0039] Reference Figures 8-10According to some embodiments of the present invention, the distance of the third tooth interval 413 is greater than the distance of the fourth tooth interval 414. Since the third tooth interval 413 is correspondingly arranged with respect to the roller 211, a sufficiently large third tooth interval 413 can ensure that the roller 211 is smoothly and without jamming when it is inserted into the third tooth interval 413, allowing the roller 211 to roll smoothly around its own axis. This avoids the roller 211 from jamming and being unable to rotate due to the distance of the third tooth interval 413 being too small. Since the fourth tooth interval 414 is correspondingly arranged with respect to the pin 212, the smaller distance of the fourth tooth interval 414 allows the pin 212 and the fourth tooth interval 414 to form a tighter fit. This reduces the gap loss caused by the excessive gap between the pin 212 and the fourth tooth interval 414, allowing power to be transmitted directly and more efficiently to the pin 212 through the fourth tooth interval 414, thereby improving the efficiency of power transmission between the second drive wheel 41 and the chain link 21.

[0040] Reference Figures 5-8 According to some embodiments of the present invention, the transmission system 100 includes two transmission systems 100, which are arranged at intervals in the axial direction of the first transmission wheel 3, and the connecting plates 5 of the two transmission systems 100 are arranged correspondingly in the horizontal direction.

[0041] With the connecting plates 5 of the two transmission systems 100 arranged correspondingly in the horizontal direction, when the material loaded by the transmission system 100 is simultaneously connected to the connecting plates 5 of the two transmission systems 100 arranged correspondingly in the horizontal direction, the horizontally corresponding connecting plates 5 can provide two points of symmetrical support in the horizontal direction, so that the load remains stable during transmission and avoids the possibility of the corresponding transmission chain 2 breaking due to excessive force on one side of the transmission system 100. This is beneficial to improving the stability and reliability of the transmission system 100 during operation.

[0042] For example, the transmission system 100 is used in the lifting device of the battery swapping station. The object being lifted is a vehicle. The two transmission systems 100 are connected by connecting plates 5 arranged in the horizontal direction. A load-bearing platform is provided between the connecting plates 5 of the two transmission systems 100. The horizontally corresponding connecting plates 5 can provide two-point symmetrical support in the horizontal direction, so that the load-bearing platform remains stable during movement. This avoids the possibility of the load-bearing platform center shifting due to single-point support, or the corresponding transmission chain 2 breaking due to excessive force on one side of the transmission system 100. This allows the vehicle to be lifted or lowered more stably.

[0043] Reference Figure 5 , Figure 6 , Figure 7 and Figure 16According to some embodiments of the present invention, the vertical circulation garage 1000 further includes: a drive member 7 and a transmission shaft 8. The drive member 7 has a drive wheel, and the transmission shaft 8 is provided with a driven wheel 81. The drive wheel and the driven wheel 81 are connected in a transmission connection. A first transmission wheel 3 is connected to each end of the transmission shaft 8.

[0044] The drive component 7 has a driving wheel, and the transmission shaft 8 has a driven wheel 81. The driving wheel and the driven wheel 81 are connected in a transmission connection. A first transmission wheel 3 is connected to each end of the transmission shaft 8. The movement of the drive component 7 can drive the driven wheel 81 to move via the driving wheel. The movement of the driven wheel 81 can drive the transmission shaft 8 to move. The movement of the transmission shaft 8 can drive the first transmission wheels 3 at both ends to move simultaneously. This can realize the transmission connection between the drive component 7 and the first transmission wheels 3 of the two transmission systems 100. It can also keep the rotation speed and direction of the two first transmission wheels 3 consistent, so as to realize the synchronous operation of the transmission chain 2 in the two transmission systems 100.

[0045] In addition, the first transmission wheel 3 of the two transmission systems 100 can be driven by a single drive member 7. Compared with the first transmission wheel 3 of each transmission system 100 being provided with a drive member 7, this can reduce the space occupied by the transmission system 100 as a whole and also reduce the number of parts, which is conducive to reducing manufacturing costs.

[0046] Reference Figure 1 and Figure 17 As shown, according to some embodiments of the present invention, the parking platform assembly 200 includes: a parking platform body 201 and a connecting frame 202. The lower end of the connecting frame 202 is connected to the parking platform body 201, and the upper end of the connecting frame 202 is rotatably connected to the connecting plate 5 via a rotating shaft 203. Because the connection is rotatable, the parking platform assembly 200 can automatically adjust its angle under gravity, maintaining a near-horizontal state in turning or inclined areas, thus improving the safety and stability of vehicles entering and exiting the parking garage. Furthermore, when the parking platform passes through a curve with a large curvature change in the guide rail 1, a rigid connection would generate a large bending moment and stress concentration, easily leading to deformation and damage to the chain, connecting parts, or frame 6. With the hinged connection via the rotating shaft 203, the parking platform assembly 200 can flexibly follow the track curve, effectively absorbing dynamic impact loads during movement, reducing fatigue damage to the transmission chain 2, connecting plate 5, and frame 6, and extending the service life of the vertical circulation parking garage 1000.

[0047] Reference Figure 18As shown, according to some embodiments of the present invention, the parking plate assembly 200 includes a protective unit 204, which includes a guide seat 2041, a push rod 2042, a main rotating shaft 2043, an active rotating rod 2044, a driven rotating rod 2045, and a stop rod 2046. One end of the push rod 2042 is connected to the guide seat 2041, and the other end of the push rod 2042 is connected to the main rotating shaft 2043 via a crank to drive the main rotating shaft 2043 to rotate. The main rotating shaft 2043 is connected to one end of the active rotating rod 2044. One end of the active rotating rod 2044 and one end of the driven rotating rod 2045 are rotatably connected to the parking plate body 201. The active rotating rod 2044 and the driven rotating rod 2045 are arranged in parallel, and the other ends of the active rotating rod 2044 and the driven rotating rod 2045 are rotatably connected to the stop rod 2046.

[0048] When the guide seat 2041 contacts the ground, it lifts up and pushes the push rod 2042 to move. The push rod 2042 then pushes the main shaft 2043 to rotate. The rotation of the main shaft 2043 causes the active rotating rod 2044 to rotate to a roughly horizontal position. The rotation of the active rotating rod 2044, through the stop lever 2046, causes the driven rotating rod 2045 to rotate to a roughly horizontal position, thus retracting the protective unit 204 for easy parking / retrieval by the driver and passengers. After the guide seat 2041 moves away from the ground, it falls down and pushes the push rod 2042 to move. The push rod 2042 then drives the main shaft 2043 to rotate. The rotation of the main shaft 2043 causes the active rotating rod 2044 to rotate to a vertical position. The rotation of the active rotating rod 2044, through the stop lever 2046, causes the driven rotating rod 2045 to rotate to a vertical position, preventing the vehicle from accidentally sliding out or foreign objects from entering the parking position, thus improving vehicle safety. Furthermore, the lifting and lowering of the protective unit 204 is achieved by the guide seat 2041 contacting or moving away from the ground, and the position adaptive lifting and lowering control of the stop lever 2046 is realized, which reduces production and maintenance costs, and at the same time reduces the failure rate.
