[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 this utility model, and should not be construed as limiting this utility model.

[0031] The following is for reference. Figures 1-12 A transmission system 100 according to an embodiment of the present utility model is described.

[0032] Reference Figures 1-4 According to the embodiment of the present utility model, the transmission system 100 includes a guide rail 1, a transmission chain 2, a first transmission wheel 3 and a slewing bearing 4. The transmission chain 2 is disposed in the guide rail 1. By disposing of the transmission chain 2 in the guide rail 1, the guide rail 1 can guide the movement path of the transmission chain 2, ensuring that the transmission chain 2 moves in a preset direction and trajectory.

[0033] 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. The slewing bearing 4 is arranged at intervals with the first transmission wheel 3. A second transmission wheel 41 is provided on the slewing bearing 4. The transmission chain 2 is wound between the first transmission wheel 3 and the second transmission wheel 41.

[0034] 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 set between two adjacent first grooves. The first transmission wheel 3 includes a first wheel body 31 and multiple first gear teeth 32 arranged along its circumferential direction. The first gear teeth 32 include a first tooth 321 corresponding to the first groove and a second tooth 322 corresponding to the second groove. The first tooth 321 and the second tooth 322 respectively mesh with the first groove and the second groove. This can form a relatively continuous and uniform meshing contact between the transmission chain 2 and the first transmission wheel 3, which is beneficial to improving the stability and reliability of the transmission between the first transmission wheel 3 and the transmission chain 2, avoiding the stress concentration problem caused by a single meshing structure, improving the transmission efficiency, and also helping to extend the service life of the transmission chain 2 and the first transmission wheel 3.

[0035] 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.

[0036] 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.

[0037] For example, compared to the shift fork drive, the shift fork drive has a small gap between the shift fork and the lower guide rail 1 during the meshing process, which is prone to interference and has a large impact and high operating noise during the driving process. 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, the continuous rolling meshing of the transmission chain 2 and the first transmission wheel 3 is realized, which avoids the problem of interference between the shift fork insertion force and the guide rail 1, reduces noise, and makes the operation of the transmission chain 2 smoother.

[0038] According to the transmission system 100 of this utility model embodiment, by having the first groove and the second groove of the transmission chain 2 correspond to the first tooth 321 and the second tooth 322 of the first transmission wheel 3 respectively, a double groove and double tooth correspondence relationship is formed, which can improve the stability and reliability of the meshing between the first transmission wheel 3 and the transmission chain 2. Furthermore, by providing a slewing bearing 4 spaced apart from the first transmission wheel 3, the slewing bearing includes a second transmission wheel 41, and the transmission chain 2 is sleeved on the first transmission wheel 3 and the second transmission wheel 41, the slewing bearing 4 can support the movement of the transmission chain 2, which can reduce the friction of the transmission chain 2 during the movement. For example, if the slewing bearing 4 is located above the first transmission wheel 3, it can effectively 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, thereby effectively improving the overall operational stability and reliability of the transmission system 100.

[0039] Reference Figure 3 , Figure 7 and Figure 8 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] Reference Figure 3 , Figure 7 and Figure 8 According to some embodiments of this utility model, 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 set 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. This avoids 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 set to the pin 212, the smaller distance of the second tooth interval 324 allows the pin 212 and the second tooth interval 324 to form a tighter fit. This reduces the gap loss caused by the excessive gap between the pin 212 and the second tooth interval 324, allowing power to be transmitted directly and more efficiently to the pin 212 through the second tooth interval 324, thereby improving the efficiency of power transmission between the first transmission wheel 3 and the chain link 21.

[0045] Reference Figures 4-6 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 along 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 arranged with the first groove, and the fourth tooth 4122 is correspondingly arranged with the second groove.

[0046] 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.

[0047] Reference Figures 4-6 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.

[0048] 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.

[0049] 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.

[0050] Reference Figures 4-6According to some embodiments of this utility model, 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 set with 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 set with 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 transmission wheel 41 and the chain link 21.

[0051] Reference Figure 2 , Figure 7 , Figure 8 and Figure 9 According to some embodiments of this utility model, it further includes a connecting plate 5 and a frame 6. The connecting plate 5 is connected to the chain link 21, and there are multiple connecting plates 5 arranged at intervals. The guide rail 1 is formed on the frame 6, and the slewing bearing 4 is disposed on the frame 6, and the relative position of the slewing bearing 4 and the frame 6 is adjustable. The frame 6 can serve as a carrier for the guide rail 1 and the slewing bearing 4, providing support and fixation for components such as the guide rail 1 and the slewing bearing 4.

[0052] The connecting plates 5 are connected to the chain links 21, and multiple connecting plates 5 are arranged at intervals. The multiple connecting plates 5 can evenly transfer the external load to different chain links 21 of the transmission chain 2, avoiding deformation or breakage of a single chain link 21 due to excessive local stress concentration. The tension of the transmission chain 2 can be flexibly adjusted according to the actual situation by adjusting the relative position of the slewing bearing 4 and the frame 6. This avoids slippage between the first transmission wheel 3 or the second transmission wheel 41 and the transmission chain 2 due to the transmission chain 2 being too loose, or increased frictional resistance between the transmission chain 2 and the first transmission wheel 3 or the second transmission wheel 41 due to the transmission chain 2 being too tight. The adjustable relative position of the slewing bearing 4 to the frame 6 allows for flexible adjustment of the tension of the transmission chain 2, which is beneficial to improving the stability of the transmission chain 2 during long-term operation.

[0053] In some embodiments, the frame 6 is provided with a mounting beam 61 and a tensioning plate 62. The mounting beam 61 can form a stable frame structure with the frame 6, distributing the load borne by the frame 6 and avoiding the possibility of deformation of the frame 6 due to excessive local stress. For example, the mounting beam 61 is provided on the frame 6 and the slewing bearing 4 is supported by the mounting beam 61. The mounting beam 61 can support the slewing bearing 4, avoiding the load of the slewing bearing 4 from acting directly on the weak parts of the frame 6, and reducing the possibility of cracking or wear due to local stress concentration in the frame 6.

[0054] The frame 6 is equipped with a tension plate 62, which is connected to the slewing bearing 4. For example, by moving the position of the tension plate 62, the slewing bearing 4 can be driven to move relative to the frame 6 in a preset direction, thereby adjusting the tension of the transmission chain 2.

[0055] Reference Figure 2 , Figure 3 , Figure 11 and Figure 12 According to some embodiments of the present invention, it also includes a driving component 7 and a transmission shaft 8. The driving component 7 is connected to the first transmission wheel 3 in a transmission connection. The driving component 7 has a driving wheel. The transmission shaft 8 is arranged coaxially with the first transmission wheel 3. A driven wheel 81 is provided on the transmission shaft 8. The driving wheel and the driven wheel 81 are connected in a transmission connection.

[0056] 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. The transmission shaft 8 and the first transmission wheel 3 are arranged coaxially. 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 wheel 3 to move, thereby realizing the transmission connection between the drive component 7 and the first transmission wheel 3. Furthermore, by arranging the transmission shaft 8 and the first transmission wheel 3 coaxially, the power transmission between the transmission shaft 8 and the first transmission wheel 3 can be more direct and efficient.

[0057] Reference Figures 1-4 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.

[0058] 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.

[0059] 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.

[0060] Reference Figure 1 , Figure 2 , Figure 3 and Figure 12 According to some embodiments of the present invention, it also includes a driving component 7 and a transmission shaft 8. The driving component 7 has a driving wheel, and the transmission shaft 8 is provided with 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.

[0061] 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.

[0062] 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.

[0063] The following will refer to Figures 1-12 A transmission system 100 according to a specific embodiment of the present invention is described.

[0064] like Figures 1-5As shown, in this embodiment, the transmission system 100 includes a frame 6, a connecting plate 5, a driving component 7, a guide rail 1, a transmission chain 2, a first transmission wheel 3, and a slewing bearing 4.

[0065] The transmission chain 2 includes multiple chain links 21 connected end to end. The connecting plate 5 is connected to the chain links 21. The connecting plate 5 includes multiple connecting plates, which are arranged at intervals along the circumference of the transmission chain 2. The transmission system 100 includes two transmission systems 100, which are arranged at intervals in the axial direction of the first transmission wheel 3. The connecting plates 5 of the two transmission systems 100 are arranged correspondingly in the horizontal direction.

[0066] The driving component 7 includes a drive motor, the motor shaft of which is connected to a drive wheel, and a driven wheel 81 is provided on the transmission shaft 8.

[0067] Each link 21 has a chain groove 22, which includes a first groove and a second groove, with a second groove arranged between every two adjacent first grooves. The first transmission wheel 3 includes a first wheel body 31 and a plurality of first gear teeth 32 arranged along the circumferential direction of the first wheel body 31. The first gear teeth 32 include first teeth 321 and second teeth 322, with the first teeth 321 corresponding to the first groove and the second teeth 322 corresponding to the second groove.

[0068] Each link 21 has 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. The distance of the first tooth gaps 323 is greater than the distance of the second tooth gaps 324. A bushing is provided on the pin 212.

[0069] The second transmission 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. The third tooth 4121 is correspondingly arranged with the first groove, and the fourth tooth 4122 is correspondingly arranged with the second groove. 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. The distance of the third tooth gap 413 is greater than the distance of the fourth tooth gap 414.

[0070] When the drive motor is running, the drive motor drives the driven wheel 81 to move through the driving wheel. The movement of the driven wheel 81 can drive the transmission shaft 8 to move. The transmission shaft 8 is connected to two first transmission wheels 3, thereby driving the first transmission wheels 3 to move. The movement of the first transmission wheels 3 can drive the transmission chain 2 to move. The movement of the transmission chain 2 can drive the second transmission wheel 41 to move, thereby realizing the reciprocating motion of the transmission chain 2.

[0071] 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. They also have a large impact during driving, resulting in high operating noise and a large axial force on the drive motor. By setting alternating first and second slots on the transmission chain 2 and having them mesh 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. This avoids the problem of interference between the shift fork insertion force and the guide rail 1, reduces noise, and makes the transmission chain 2 run more smoothly. Furthermore, the first transmission wheel 3 allows for a larger reduction ratio and a smaller transmission radius, effectively reducing the torque requirement of the drive motor and the radial force on the drive motor shaft, which helps to reduce energy consumption.

[0072] For example, compared to toothed chain pin drive systems, the limited thickness of the chain links in the toothed chain pin drive system 100 results in a limited contact area between the tooth surface and the pin 212. When the drive system 100 is applied to a high-rise multi-level parking garage, the contact stress is too high, causing the pin 212 and sleeve to wear easily, requiring extremely high material strength. By forming multiple chain grooves 22 on the chain link 21 and arranging them alternately, the number of meshing points between the first drive wheel 3 and the drive chain 2 is increased, significantly dispersing the force, reducing the surface contact stress per unit contact area, reducing wear on components, and reducing dependence on material strength, thereby improving the reliability and durability of the drive system 100.

[0073] By setting a slewing bearing 4 at the top, and adjusting the position of the slewing bearing 4 relative to the frame 6 to adjust the tension of the transmission chain 2, the output torque of the drive component 7, including the drive wheel, can be reduced by decreasing its size, for example, by increasing the thickness of the drive wheel to reduce the unit surface contact stress. Furthermore, the chain link 21 of the transmission chain 2 is provided with a pin 212, and the pin 212 is provided with a bushing. Compared to the shift fork and pin gear transmission scheme, this makes the operation of the transmission system 100 smoother, the structure simpler, and easier to process and install, with better applicability compared to gear transmission schemes.

[0074] By corresponding the first and second grooves of the transmission chain 2 with the first tooth 321 and the second tooth 322 of the first transmission wheel 3, a double-groove and double-tooth correspondence is formed, which can improve the stability and reliability of the meshing between the first transmission wheel 3 and the transmission chain 2. Furthermore, by providing a slewing bearing 4 spaced apart from the first transmission wheel 3, the slewing bearing includes a second transmission wheel 41, and the transmission chain 2 is sleeved on the first transmission wheel 3 and the second transmission wheel 41. The slewing bearing 4 can support the movement of the transmission chain 2 and reduce the friction of the transmission chain 2 during movement. For example, if the slewing bearing 4 is located above the first transmission wheel 3, it can effectively reduce the lifting friction of the transmission chain 2, making the movement of the transmission chain 2 smoother and reducing the noise generated when the transmission chain 2 moves, thereby effectively improving the overall operational stability and reliability of the transmission system 100.
