[0002] Currently, electric vehicles (including but not limited to electric bicycles and electric motorcycles) are a common mode of transportation. Common electric vehicle parking equipment typically uses a platform to hold the vehicles, with locking devices installed on it to secure them. One type of locking device primarily locks the wheels, but this type has some drawbacks. It generally requires manual locking by the user, which is inconvenient. Furthermore, it usually only fits a single model of electric vehicle, lacking versatility. For electric vehicles with different wheel sizes (diameter, width, etc.), multiple different locking devices are needed, resulting in low parking space utilization and increased equipment and operating costs, thus hindering the widespread adoption of electric vehicle parking equipment.

Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0045] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0046] The vehicle carrier assembly in this application is used to support electric vehicles and can be applied to electric vehicle parking equipment, such as multi-level electric vehicle parking garages, for parking electric vehicles. The electric vehicles in this application include, but are not limited to, electric bicycles and electric motorcycles.

[0047] In the embodiments described below, for ease of description, the lateral direction of the vehicle platform assembly is taken as the first horizontal direction, the longitudinal direction of the vehicle platform assembly is taken as the second horizontal direction, and the height direction is taken as the third horizontal direction; wherein, the lateral and longitudinal directions of the vehicle platform assembly are consistent with the lateral and longitudinal directions of the electric vehicle it carries, which will not be repeated below.

[0048] The following describes some embodiments of the vehicle platform assembly and electric vehicle automated parking system provided in this application, with reference to the accompanying drawings.

[0049] An embodiment of the first aspect of this application provides a vehicle platform assembly 3, such as Figure 1 , Figure 2 As shown, the vehicle platform assembly 3 includes a vehicle platform 31 and a locking device 32. The vehicle platform 31 serves as a support platform for the electric vehicle 5, and its top surface can support the electric vehicle 5. One end of the vehicle platform 31 has an installation structure 3121 that can be connected to a lifting device. When the vehicle platform assembly 3 is applied to an electric vehicle automated parking system, it can be connected and installed to the lifting device through the installation structure 3121, so that the vehicle platform 31 can move up and down with the lifting device. The vehicle platform 31 is provided with a locking device 32, which is used to lock the wheels 51 of the electric vehicle 5 to enable locking operation. At the same time, it can keep the electric vehicle 5 stable on the vehicle platform 31 so that it can move up and down with the vehicle platform 31. The locking device 32 includes a movable part 320 and a fixed part 322. The fixed part 322 is fixedly connected to the vehicle platform 31. The movable part 320 is correspondingly arranged with the fixed part 322, and at least a portion of the movable part 320 can be flipped and horizontally slid relative to the vehicle platform 31 to adjust the posture of the movable part 320 and the distance between it and the fixed part 322. The movable part 320 has a first corner position and a second corner position. When the movable part 320 is in the first corner position, such as... Figure 3 In the example, the wheel 51 of the electric vehicle 5 can move onto the movable part 320. The movable part 320 can be flipped to a second corner position, causing the wheel 51 to move towards the fixed part 322. At the same time, the movable part 320 is connected to the vehicle platform 31, so that the wheel 51 is locked in place by the movable part 320 and the fixed part 322. Figure 4The state shown in the diagram locks wheel 51.

[0050] When using, such as Figure 3 and Figure 4 In the example, initially, the movable part 320 is located at the first corner position. By pushing the electric vehicle 5 onto the vehicle carrier 31, the front wheel of the electric vehicle 5 presses onto the movable part 320. The pressure of the wheel 51 causes the movable part 320 to flip from the first corner position to the second corner position. Simultaneously, the movable part 320 connects with the vehicle carrier 31, and the front and rear ends of the wheel 51 abut against the fixed part 322 and the movable part 320 respectively, and are locked in place. Depending on the size of the wheel 51, the movable part 320 can slide horizontally relative to the vehicle carrier 31, so that the distance between the movable part 320 and the fixed part 322 matches the size of the wheel 51, ensuring that the front and rear ends of the wheel 51 abut against the fixed part 322 and the movable part 320 respectively, thus achieving the locking operation. When it is time to retrieve the vehicle, simply unlock the movable part 320 from the vehicle carrier plate 31 by operating the mechanism. This releases the wheel 51 from its jamming state, allowing the electric vehicle 5 to be pushed away from the fixed part 322. The wheel 51 then moves in the opposite direction out of the movable part 320 to perform the vehicle retrieval operation.

[0051] It should be noted that the connection between the movable part 320 and the vehicle platform 31 at the second corner position is a detachable connection, including but not limited to snap-fit ​​and magnetic connection. In addition, in practical applications, the movable part 320 and the fixing part 322 can be configured to fit the shape of the wheel 51 so as to secure the wheel 51.

[0052] The vehicle carrier assembly 3 in this embodiment simplifies the structure and locking operation of the locking device 32 through structural optimization and improvement. It can achieve automatic locking and can adaptively adjust the position and posture of the movable part 320 according to the different sizes of the wheels 51. It has stronger versatility and can be adapted to electric vehicles 5 with different wheel sizes 51. When applied to electric vehicle parking equipment, it is not necessary to equip different locking devices 32 for different models of electric vehicles. It has a wider range of applications, which helps to reduce equipment costs and operating costs and facilitates promotion and application.

[0053] In further embodiments of this application, such as Figure 5 , Figure 6As shown, the movable part 320 and the fixed part 322 of the locking device 32 are arranged opposite to each other and spaced apart in the second horizontal direction to reserve space for the wheel 51 of the electric vehicle 5. The movable part 320 includes two clamping arms 321, which are arranged opposite to each other in the first horizontal direction. Both clamping arms 321 are rotatably connected to the vehicle carrier plate 31 to form a lever-like structure, allowing the clamping arms 321 to rotate relative to the vehicle carrier plate 31 in the vertical plane. Each clamping arm 321 is provided with multiple bearing plates 3213, and the bearing plates 3213 on the two clamping arms 321 are correspondingly arranged so that when the wheel 51 of the electric vehicle 5 enters the movable part 320, it contacts the wheel 51 through the bearing plates 3213 to provide support. The rotation axes of the two clamping arms 321 are intersecting each other and form a first included angle α facing the fixed part 322. The angle α ranges from 150° to 170°. Figure 6 In the example, preferably, the first included angle α can be 150°, 155°, 160°, 165°, or 170°; when the two clamping arms 321 are flipped from the first corner position to the second corner position, the distance between the two bearing plates 3213 arranged opposite each other in the first horizontal direction is reduced, so that clamping can be formed on both sides of the wheel 51 in the width direction of the wheel 51 (i.e., the first horizontal direction) to limit and fix the wheel 51, thereby further enhancing the stability of the locking mechanism.

[0054] Furthermore, such as Figures 5 to 7 As shown, the clamping arm 321 of the movable part 320 specifically includes a first clamping part 3211 and a second clamping part 3212 connected to each other. In the second horizontal direction, the connection point of the first clamping part 3211 and the second clamping part 3212 is the rotation center position of the clamping arm 321. The first clamping part 3211 is located on the side of the rotation center away from the fixed part 322, and the second clamping part 3212 is located on the side of the rotation center facing the fixed part 322. The first clamping part 3211 and the second clamping part 3212 form a second included angle b in the vertical plane. The second included angle b faces upward towards the vehicle platform 31, and the angle range of the second included angle b is 90° to 120°. Figure 8 In the example, preferably, the second included angle b can be 90°, 100°, 110°, or 120°. When the clamping arm 321 is in the first corner position, the first clamping part 3211 abuts against the vehicle platform 31, and the second clamping part 3212 tilts upward. After the wheel 51 enters the bearing range of the clamping arm 321, the clamping arm 321 flips from the first corner position to the second corner position. At this time, the second clamping part 3212 abuts against the vehicle platform 31, and the first clamping part 3211 tilts upward. The first clamping part 3211 is located behind the wheel 51 and, together with the fixing part 322, clamps the wheel 51 from both front and rear directions to secure the wheel 51.

[0055] Specifically, such as Figures 5 to 7 In the example, each clamping arm 321 has a support plate 3213 on its first clamping part 3211 and second clamping part 3212, and in the first horizontal direction, the support plates 3213 on the two first clamping parts 3211 are arranged opposite to each other, and the support plates 3213 on the two second clamping parts 3212 are arranged opposite to each other. Each support plate 3213 includes a support side plate 32132 and a support bottom plate 32131 connected to each other. The support side plate 32132 is connected to the side of the support bottom plate 32131 away from the other support plate 3213 in the first horizontal direction. That is, the support side plates 32132 on the corresponding two support plates 3213 are respectively located near the outer side of the corresponding support bottom plate 32131. At the same time, the side of the support bottom plate 32131 away from the corresponding support side plate 32132 has a plurality of toothed plate structures 32133. The plurality of toothed plate structures 32133 are spaced apart in the second horizontal direction, and the toothed plate structures 32133 on the corresponding two support plates 3213 are intersected to compensate for the gap between the two support bottom plates 32131. When the wheel 51 enters the support plate 3213, the bottom of the wheel 51 is supported by the two support plates 3213 and the multiple intersecting toothed plate structures 32133. At the same time, the two opposite support side plates 32132 limit the movement of the wheel 51 on both sides. In particular, after the clamping arm 321 flips from the first corner position to the second corner position, the lateral distance between the two clamping arms 321 decreases, which in turn reduces the distance between the corresponding two support side plates 32132, thereby clamping the wheel 51 from both sides.

[0056] Furthermore, in a specific example, such as Figure 7 In the example, in each support plate 3213, the support side plates 32132 are all inclined in the first horizontal direction away from the corresponding support plate 3213, so that the two corresponding support plates 3213 cooperate to form a funnel-shaped opening structure. That is, the distance between the two cooperating support side plates 32132 in the first horizontal direction gradually increases from bottom to top, thereby accommodating wheels 51 of different widths. When the wheel 51 is relatively wide, the wheel 51 can also be directly engaged between the two support side plates 32132 without contacting the support base plate 32131, which can also lock the wheel 51, thereby further increasing the adaptability range of the locking device 32 to the size of the wheel 51. In each bearing plate 3213, a third included angle c is formed between the bearing side plate 32132 and the bearing bottom plate 32131. The third included angle c faces away from the vehicle plate 31, and the angle range of the third included angle c is 120° to 150°. Preferably, the third included angle c can be 120°, 130°, 140°, or 150°.

[0057] Furthermore, in a specific example, such as Figure 1 and Figure 5 In the example shown, a guide groove 3111 is provided on the top surface of the vehicle carrier plate 31. The guide groove 3111 is recessed downward and is correspondingly provided with the movable part 320 in the second horizontal direction. The guide groove 3111 extends along the second horizontal direction and extends to the bottom of the movable part 320. Accordingly, when the movable part 320 is in the first corner position, the bottom of the first clamping part 3211 can extend into the guide groove 3111 and abut against the bottom wall of the guide groove 3111, so as to guide the wheel 51 of the electric vehicle 5 through the guide groove 3111. The wheel 51 can enter the first clamping part 3211 of the movable part 320 along the guide groove 3111. In addition, the guide groove 3111 can also provide lateral restraint for the wheel 51 of the electric vehicle 5, preventing the wheel 51 from deviating from its trajectory and making it difficult to accurately align with the carrier plate 3213 of the movable part 320, which helps to improve the convenience of locking the vehicle. Preferably, as shown in the example Figure 5 In the example, the two side walls of the guide groove 3111 can be set as inclined structures, with the inclination direction consistent with the inclination direction of the two corresponding bearing side plates 32132, so that the wheel 51 can enter the guide groove 3111.

[0058] Furthermore, in a specific example, such as Figure 7 In the example, the toothed plate structure 32133 of each support plate 3213 extends from the edge of the support base plate 32131 toward the opposite support plate 3213, and at least a portion of the toothed plate structure 32133 is inclined upward relative to the support base plate 32131. When the clamping arm 321 flips from the first corner position to the second corner position, the lateral distance between the two clamping arms 321 decreases, and the lateral distance between the support plates 3213 also decreases accordingly. The toothed plate structure 32133 of the support plate 3213 is closer to the other support plate 3213, and the upwardly positioned toothed plate structure 32133 can avoid mutual collision or interference with the other support plate 3213.

[0059] Furthermore, in a specific example, such as Figure 5 , Figure 9 , Figure 10As shown, the second clamping part 3212 of the clamping arm 321 is provided with a first connecting structure 3214 on the side facing the vehicle platform. Correspondingly, a second connecting structure 3112 is provided at a corresponding position on the vehicle platform. The first connecting structure 3214 and the second connecting structure 3112 are electromagnetic structures with opposite magnetic pole directions. When the second clamping part 3212 is flipped to the second corner position, the first connecting structure 3214 can be attracted and connected to the second connecting structure 3112 to keep the second clamping part 3212 in the second corner position to keep the wheel 51 locked. When unlocking is required, the electromagnetic structure can be de-energized to make the magnetic attraction disappear, and the clamping arm 321 can be flipped in the opposite direction to perform the vehicle retrieval operation. The clamping arm 321 has a torsion spring 3216 sleeved on its rotating shaft 3215. The torsion spring 3216 abuts against the second clamping part 3212 and the vehicle plate respectively. When the second clamping part 3212 is flipped to the second corner position, the torsion spring 3216 is twisted and tends to return to its original state. When the first connecting structure 3214 is separated from the second connecting structure 3112, the clamping arm 321 can be flipped to the first corner position under the torsion of the torsion spring 3216 to achieve automatic reset.

[0060] In further embodiments of this application, such as Figure 1 , Figure 8 and Figure 9As shown, a groove 3113 extending along a second horizontal direction is provided on the top surface of the vehicle carrier plate 31. The groove 3113 is correspondingly provided with the fixed part 322 to allow the movable part 320 to slide. Correspondingly, the locking device 32 also includes a slide 323 and a tension spring 324. The slide 323 is slidably connected to the groove 3113, and the movable part 320 is disposed on the slide 323 and fixedly connected to the slide 323, so that the movable part 320 can slide along the second horizontal direction with the slide 323 as a whole, thereby adjusting the distance between the movable part 320 and the fixed part 322 to adapt to wheels 51 of different sizes. The tension spring 324 is arranged along the second horizontal direction. One end of the tension spring 324 is connected to the slide 323, and the other end is connected to the vehicle platform 31. When the wheel 51 with a larger diameter enters the movable part 320 and the clamping arm 321 of the movable part 320 is rotated to the second corner position, the front end of the wheel 51 abuts against the fixed part 322, and the first clamping part 3211 of the clamping arm 321 abuts against the rear end of the wheel 51. The wheel 51 is pushed by the reverse force of the fixed part 322 to slide the slide 323 away from the fixed part 322. The distance between the movable part 320 and the fixed part 322 is increased so that the bottom of the wheel 51 can abut against the second clamping part 3212 or the vehicle platform 31. At the same time, the tension spring 324 is stretched so that the first clamping part 3211 of the movable part 320 maintains a certain pressure on the rear end of the wheel 51 so that the wheel 51 can be clamped by the first clamping part 3211 and the fixed part 322. After the wheel 51 separates from the movable part 320, the movable part 320 and the carriage 323 can be reset under the tension of the tension spring 324.

[0061] It should be noted that the number of grooves 3113 can be as follows: Figure 9 The two shown correspond to each other, with the two sides of the carriage 323 slidably connected to two slide grooves 3113 respectively. Of course, in practical applications, the number of slide grooves 3113 can also be adjusted according to the actual situation, for example, one or more than two other numbers can be set.

[0062] Furthermore, in a specific example, such as Figure 2 , Figure 5 and Figure 9In the example shown, the locking device 32 further includes a locking hook mechanism 325, which is disposed on the side of the second clamping portion 3212 in the first horizontal direction. The locking hook mechanism 325 is rotatably connected to the vehicle carrier plate 31 and can rotate relative to the vehicle carrier plate 31. Correspondingly, the second clamping portion 3212 has a plurality of locking hole structures 32121, which are spaced apart along the extending direction of the second clamping portion 3212. When the clamping arm 321 is in the second corner position and clamps the wheel 51, the locking hook mechanism 325 can be rotated to engage with a corresponding locking hole structure 32121 on the second clamping portion 3212, thereby providing a safety protection function. The locking hook mechanism 325 can be operated manually or driven by a corresponding drive mechanism.

[0063] Furthermore, in a specific example, such as Figure 10 In the example, the vehicle platform 31 specifically includes a vehicle platform body 311 and a connecting frame 312. The vehicle platform body 311 is arranged horizontally to support the electric vehicle 5; the vehicle platform body 311 is generally a rectangular plate structure, with its length direction consistent with the second horizontal direction and its width direction consistent with the first horizontal direction. The connecting frame is arranged vertically and is connected to one end of the vehicle platform body 311 in the second horizontal direction; the mounting structure 3121 is arranged on the connecting frame 312 to facilitate connection and installation with the lifting device. The fixing part 322 is arranged on the side of the connecting frame 312 facing the vehicle platform body 311, and the movable part 320 is arranged on the vehicle platform body 311 and is arranged opposite to the fixing part 322; the side of the fixing part 322 facing the movable part 320 has a fixing groove 3221 for accommodating the wheel 51. In the first horizontal direction, the two side walls of the fixing groove 3221 are inclined to both sides so that the cross-sectional shape of the fixing groove 3221 forms a trumpet-like structure to adapt to wheels 51 of different widths. Preferably, the vehicle platform body 311 and the connecting frame 312 are made of high-strength aluminum alloy. The connection between the connecting frame 312 and the vehicle platform body 311 can also be provided with a corresponding reinforcing plate or reinforcing rod to improve the overall connection strength of the vehicle platform 31.

[0064] Furthermore, in a specific example, such as Figure 10 In the example shown, a charging device 33 is also provided on the vehicle carrier 31. The electric vehicle 5 supported on the vehicle carrier 31 can be electrically connected to the charging device 33 via a charging cable to charge the electric vehicle 5. The specific location of the charging device 33 can be set according to actual needs, for example, it can be set on the connecting frame 312 or on the vehicle carrier body 311; the charging device 33 can be entirely located on the vehicle carrier 31, or a charging interface or adapter can be set only on the vehicle carrier 31 and connected to an external power source through a corresponding cable.

[0065] Furthermore, in a specific example, such as Figure 10 In the example, in the first horizontal direction, protective railings 313 are also provided on both sides of the vehicle platform 31.

[0066] An embodiment of the second aspect of this application provides an electric vehicle automated parking garage 100, such as... Figure 1 , Figure 11 , Figure 12 As shown, the electric vehicle automated parking garage 100 includes a main frame 1, a circulating lifting device 2, a vehicle-carrying plate assembly 3 as described in any of the above embodiments, and a controller 4. The main frame 1 serves as a mounting base, used for installation and fixation to the mounting surface, and can support and fix the circulating lifting device 2, the vehicle-carrying plate assembly 3, and the controller 4. The main frame 1 is arranged along the height direction, and a circulating track 12 is provided on the main frame 1. The circulating track 12 is located in a vertical plane and is a closed structure. The circulating lifting device 2 is correspondingly connected to the main frame 1, arranged along the height direction and corresponding to the circulating track 12. The circulating lifting device 2 has a motion mechanism that can circulate along the circulating track 12. Multiple vehicle-carrying plate assemblies 3 are connected at intervals on the motion mechanism. The vehicle-carrying plate assemblies 3 are used to park electric vehicles 5, and the locking devices 32 on the vehicle-carrying plate assemblies 3 can lock the wheels 51 of the electric vehicles to achieve vehicle locking. The controller 4 is communicatively connected to the circulating lifting device 2 to control the circulating lifting device 2. When the motion mechanism moves along the circular track 12, it drives multiple vehicle platform assemblies 3 to move synchronously, so that the multiple vehicle platform assemblies 3 can move up and down in the vertical plane. When any vehicle platform assembly 3 moves to the bottom, the user can park or retrieve the vehicle from that vehicle platform assembly 3.

[0067] It's understandable that existing electric vehicle parking garages typically employ a combination of conventional vertical lifting mechanisms and horizontal movement mechanisms to achieve multi-level parking. The lifting mechanisms require fixed vertical lifting channels, and after reaching a designated level, horizontal movement mechanisms are needed to transport the vehicle to or from the designated location onto the lifting mechanism. Only one electric vehicle can be operated at a time, and this process is time-consuming and inefficient. If a large number of parking spaces are provided, waiting times become excessively long. Increasing the number of lifting mechanisms, however, increases equipment costs and occupies more space. Therefore, existing multi-level parking garages generally adopt a compact design (e.g., two or three levels), accommodating a limited number of parking spaces.

[0068] The electric vehicle automated parking garage 100 in this embodiment, through structural improvements and optimizations, adopts a circulating lifting device 2 to circulate within the three-dimensional space, which can significantly improve the transportation efficiency of electric vehicles and greatly shorten the time required for parking and retrieving vehicles. Compared with existing parking garages, it can set up more parking spaces, making it suitable for application in large and medium-sized parking lots. Moreover, it does not require the configuration of a corresponding horizontal transportation mechanism, has a relatively simple structure, and relatively low equipment costs, which is conducive to its widespread application.

[0069] It should be noted that the main frame 1 is not limited to the rectangular frame structure shown in the figure, and other frame structures can be used as needed. The motion mechanism of the circulating lifting device 2 can rotate clockwise or counterclockwise as needed.

[0070] In further embodiments of this application, such as Figure 13 , Figure 14 and Figure 15 As shown, in the electric vehicle automated parking garage 100, the circulating lifting device 2 includes a slide rail frame 21, a first sprocket assembly 22, and a drive mechanism 23. The slide rail frame 21 is connected to the main frame 1 and is arranged vertically. In the first horizontal direction, the two side edges of the slide rail frame 21 form a slide rail structure 211. Correspondingly, the first sprocket assembly 22 includes a first driving gear 221, a first driven gear 222, and a first transmission chain 223. The first driving gear 221 and the first driven gear 222 are respectively located at both ends of the slide rail frame 21 in the height direction, and there is a certain gap between them in the height direction to avoid mutual interference. The first transmission chain 223 is wound around the first driving gear 221 and the first driven gear 222 to form mutual meshing, and the first transmission chain 223 is slidably engaged with the slide rail structures 211 on both sides of the slide rail frame. The drive mechanism 23 is installed on the main frame 1 at a position corresponding to the first drive gear 221, and the drive mechanism 23 is connected to the first drive gear 221 in a transmission manner to drive the first drive gear 221 to rotate, thereby driving the first transmission chain 223 to move along the circular track 12. The first transmission chain 223 forms the motion mechanism of the circular lifting device 2, and its motion trajectory is adapted to the circular track 12. The vehicle platform assembly 3 is connected to the first transmission chain 223 and is located on one side of the first transmission chain 223 in the second horizontal direction, offset from the main frame 1. When the first transmission chain 223 moves along the circular track 12 under the drive of the first drive gear 221, multiple vehicle platform assemblies 3 move synchronously with the first transmission chain 223, realizing the lifting and lowering operation of the vehicle platform assemblies 3.

[0071] By setting up the slide rail frame 21, the first transmission chain 223 is slidably engaged with the slide rail, which guides and limits the first transmission chain 223, preventing it from swaying during movement and improving motion stability. Furthermore, compared to synchronous belt drives, the chain drive method used in this embodiment is less prone to slippage, has a stronger load-bearing capacity, and can support a larger number of electric vehicles 5.

[0072] Furthermore, such as Figure 13 and Figure 15 As shown, the first drive gear 221 of the first sprocket assembly 22 is located above the slide rail frame 21, and correspondingly, the first driven gear 222 is located below the slide rail frame 21. The drive mechanism 23 is correspondingly arranged with the first drive gear 221, so that it can be staggered from other mechanisms below the slide rail frame 21 to avoid interference. The drive mechanism 23 includes a drive motor 231 and a second sprocket assembly 232. The second sprocket assembly 232 specifically includes a second driving gear 2321, a second driven gear 2322, and a second transmission chain 2323. The second driven gear 2322 is coaxially arranged with the first driving gear 221 and connected via a rotating shaft 3215. The second driving gear 2321 is located below the second driven gear 2322, and the second transmission chain 2323 meshes with both the second driving gear 2321 and the second driven gear 2322. The drive motor 231 is connected to the second driving gear 2321 to drive its rotation, and via the second transmission chain 2323, drives the second driven gear 2322 and the first driving gear 221 to rotate synchronously, causing the first transmission chain 223 to move accordingly. Both the second driving gear 2321 and the drive motor 231 are located below the second driven gear 2322 to utilize the space below them for efficient spatial arrangement and avoid occupying excessive space in the vertical direction.

[0073] It should be noted that, as Figure 15 In the example, the diameter of the second driving gear 2321 can be set to be smaller than the diameter of the second driven gear 2322, so as to reduce the speed of the second driven gear 2322 through the transmission ratio and achieve a deceleration effect; or, a drive motor 231 with deceleration function, such as a geared motor, can be used to reduce the output speed, thereby meeting the motion speed requirements of the first transmission chain 223.

[0074] Furthermore, such as Figure 16 , Figure 17 and Figure 18In the example, a plurality of connectors 224 are connected to the first transmission chain 223, and the connectors 224 are spaced apart on the first transmission chain 223, with each connector 224 corresponding to one of the vehicle platform assemblies 3. Correspondingly, a balance guide wheel assembly 24 is connected to each vehicle platform assembly 3, and the balance guide wheel assembly 24 is rotatably connected to a corresponding connector 224 so that the vehicle platform assembly 3 is connected to the connector 224 and can circulate with the first transmission chain 223. At least two guide wheels in each balance guide wheel assembly 24 form a rolling engagement with the circulating track 12 so that the vehicle platform assembly 3 can always remain in a horizontal state during the circulating motion with the first transmission chain 223, thereby preventing the electric vehicle 5 on the vehicle platform assembly 3 from tipping over. It is understood that the connector 224 is fixedly connected to the first transmission chain 223. As the first transmission chain 223 moves, the orientation of the connector 224 will inevitably change. The vehicle platform assembly 3 is rotatably connected to the connector 224 through the balance guide wheel assembly 24. The connector 224 and the vehicle platform assembly 3 can rotate relative to each other, and the vehicle platform assembly 3 is kept horizontal under the cooperation of the guide wheel and the circulating track 12.

[0075] Furthermore, such as Figure 17 , Figure 19 As shown, the balance guide wheel assembly 24 includes a balance shaft 241, a first balance mechanism 242, and a second balance mechanism 243. The balance shaft 241 is arranged along a second horizontal direction and rotatably passes through the connector 224; one end of the balance shaft 241 is connected and fixed to the vehicle platform assembly 3, and the first balance mechanism 242 and the second balance mechanism 243 are connected to the balance shaft 241 near the other end. The first balance mechanism 242 is arranged vertically, and each end is connected to a first balance guide wheel 2421, the rotation axes of which are both arranged along the second horizontal direction; the second balance mechanism 243 is arranged along a first horizontal direction, and each end is connected to a second balance guide wheel 2431, the rotation axes of which are both arranged along the second horizontal direction; the first balance mechanism 242 and the second balance mechanism 243 form a cross shape and are spaced apart in the second horizontal direction to avoid mutual interference.

[0076] Correspondingly, the motion trajectory of the first transmission chain 223 includes two arc-shaped motion segments and two straight motion segments. The two arc-shaped motion segments are arranged opposite each other in the height direction, and the two straight motion segments extend along the height direction and are connected to the two arc-shaped motion segments in sequence to form a closed motion trajectory with the beginning and end connected. The circular track 12 of the main frame 1 is adapted to the motion trajectory of the first transmission chain 223 and is correspondingly arranged; the connecting member 224 on the first transmission chain 223 passes through the straight motion segment and the arc-shaped motion segment in sequence as the first transmission chain 223 moves, that is, the connecting member 224 alternately passes through the straight motion segment and the arc-shaped motion segment in the circular motion process. When the connector 224 is in the linear motion segment, both first balance guide wheels 2421 of the first balance mechanism 242 form a rolling engagement with the circulating track 12. The force exerted by the circulating track 12 on the two first balance guide wheels 2421 ensures that the vehicle platform assembly 3 remains horizontal during the linear motion. When the connector 224 is in the arc motion segment, one corresponding first balance guide wheel 2421 in the first balance mechanism 242 and one corresponding second balance guide wheel 2431 in the second balance mechanism 243 form a rolling engagement with the circulating track 12. The force exerted by the circulating track 12 on the first balance guide wheel 2421 and the second balance guide wheel 2431 ensures that the vehicle platform assembly 3 remains horizontal during the arc motion.

[0077] Furthermore, in a specific example, such as Figure 15 , Figure 17 , Figure 18As shown, the circulating track 12 specifically includes two first arc-shaped guide rails 121, two linear guide rails 122, two second arc-shaped guide rails 123, and two third arc-shaped guide rails 124. The two first arc-shaped guide rails 121 are arranged opposite each other in the height direction. The two linear guide rails 122 are in the same vertical plane as the two first arc-shaped guide rails 121 and are positioned between the two first arc-shaped guide rails 121 along the height direction. One of the linear guide rails 122 has its two ends connected to one end of each of the two first arc-shaped guide rails 121, and the other linear guide rail has its two ends connected to the other ends of each of the two first arc-shaped guide rails 121, thus forming a closed guide rail structure to correspond to the movement trajectory of the first transmission chain 223. Specifically, in the first horizontal direction, with the rotation center of the first sprocket assembly 22 as the critical point, the first arc-shaped guide rail 121 specifically includes two interconnected arc-shaped segments located on either side of the critical point. Correspondingly, the second arc-shaped guide rail 123, the third arc-shaped guide rail 124, and the first arc-shaped guide rail 121 are arranged sequentially at intervals in the second horizontal direction, that is, each first arc-shaped guide rail 121 is correspondingly arranged with one second arc-shaped guide rail 123 and one third arc-shaped guide rail 124; and in the first horizontal direction, the second arc-shaped guide rail 123 is located on one side of the critical point and corresponds to one of the arc segments of the first arc-shaped guide rail 121, and the third arc-shaped guide rail 124 is located on the other side of the critical point and corresponds to the other arc segment of the first arc-shaped guide rail 121; the second arc-shaped guide rail 123 smoothly transitions with one of the straight guide rails 122, and the third arc-shaped guide rail 124 smoothly transitions with the other straight guide rail 122.

[0078] During use, as the connecting member 224 moves with the first transmission chain 223, when the moving part is in a linear motion segment, the two first balance guide wheels 2421 of the first balance mechanism 242 simultaneously roll with the corresponding linear guide rail 122; when the moving part is in an arc-shaped motion segment, the first balance guide wheel 2421 that is close to the first arc-shaped guide rail 121 in the height direction rolls with the first arc-shaped guide rail 121, wherein, for example... Figure 16 In the example, when the first balancing guide wheel 2421 is located in an arc segment to the left of the first arc-shaped guide rail 121, a second balancing guide wheel 2431 on the left side of the second balancing mechanism 243 rolls with the second arc-shaped guide rail 123 on the left side. When the first balancing guide wheel 2421 is located in an arc segment to the right of the first arc-shaped guide rail 121, a second balancing guide wheel 243 on the right side rolls with the third arc-shaped guide rail 124 on the right side.

[0079] With the above settings, the vehicle platform assembly 3 can be kept in a horizontal state whether the connector 224 is moving in the linear motion segment or the arc motion segment. Moreover, it can maintain a smooth transition when moving from the linear motion segment to the arc motion segment or from the arc motion segment to the linear motion segment, thereby enhancing the motion stability of the moving parts and the vehicle platform assembly 3.

[0080] Among them, such as Figure 18 In the example, the connector 224 can be a block or shell structure, and is clamped and connected to both sides of the chain of the first transmission chain 223 by means of pins or bolts.

[0081] Furthermore, in a specific example, such as Figure 15 , Figure 16 as well as Figure 18 , Figure 19 In the example shown, the main frame 1 is also provided with a mating frame 13. The mating frame 13 is arranged along the height direction and has an assembly space 131 that extends along the second horizontal direction; the slide rail frame 21 and the first sprocket assembly 22 are arranged in the assembly space 131 of the mating frame 13, and the inner contour of the assembly space 131 is adapted to the movement trajectory of the first transmission chain 223. Correspondingly, the connector 224 is provided with a plurality of second guide wheels 2241 on both sides of the second horizontal direction, and the rotation axis of the second guide wheels 2241 is located in the vertical plane; on either side of the connector 224 in the second horizontal direction, a portion of the second guide wheels 2241 are in rolling engagement with the slide rail frame 21 or the first sprocket assembly 22, and another portion of the second guide wheels 2241 are in rolling engagement with the mating frame 13.

[0082] Specifically, such as Figure 18 and Figure 19 In the example shown, the connector 224 has multiple second guide wheels 2241 (e.g., six as shown in the figure) on each side of the second horizontal direction. These second guide wheels 2241 are arranged side-by-side, with some extending towards the first sprocket mechanism and others towards the mounting frame 13. During the cyclical movement of the connector 224 along the first transmission chain 223, the orientation of the rotation axis of the second guide wheels 2241 changes, but they remain in the vertical plane. For example... Figures 18 to 20 The state shown is as follows. When the moving part moves with the first transmission chain 223, the second guide wheel 2241 extending toward the mating frame 13 is always in rolling engagement with the two side surfaces of the mating frame 13; when the moving part is in the linear motion segment, the second guide wheel 2241 extending toward the first sprocket assembly 22 is in rolling engagement with the two side surfaces of the slide rail frame 21; when the moving part is in the arc motion segment, the second guide wheel 2241 extending toward the first sprocket assembly 22 is in rolling engagement with the two side surfaces of the corresponding first driving gear 221 or first driven gear 222.

[0083] By setting the second guide wheel 2241, the pitch swing of the connector 224 can be prevented, and the connector 224 can always be in a vertical state, thereby preventing the vehicle platform assembly 3 connected to the connector 224 from swinging, and further enhancing the stability of the vehicle platform assembly 3.

[0084] In further embodiments of this application, such as Figure 13 , Figure 14 As shown, in a specific example, the main frame 1 adopts a cuboid frame structure, specifically including a first vertical frame 111, a first side frame 112, and a top frame 113, all of which are rectangular. There are two first side frames 112, connected to both sides of the first vertical frame 111 in the first horizontal direction and perpendicular to the first vertical frame 111. The top frame 113 connects to the top of the first vertical frame 111 and the first side frames 112, and is arranged along the horizontal plane to form a cuboid frame structure. In the second horizontal direction, the side opposite the first vertical frame 111 is an open structure to facilitate the installation of the circulating lifting device 2 and the vehicle platform assembly 3. The bottoms of the first vertical frame 111 and the first side frames 112 can be fixed to the mounting base. Appropriate baffles can also be provided on the top frame 113 as needed.

[0085] In further embodiments of this application, such as Figure 11 and Figure 21 In the example shown, the main frame 1 in another specific example adopts an inverted triangular three-dimensional frame; the main frame 1 specifically includes a bottom frame 116, a second vertical frame 115, and two second side frames 117; the second vertical frame 115 is arranged perpendicularly to the bottom frame 116, that is, the second vertical frame 115 is arranged in the vertical direction, and the bottom frame 116 is arranged in the horizontal direction, and the two are connected to form an L-shaped structure; the two second side frames 117 are spaced apart in the first horizontal direction and are located on both sides of the second vertical frame 115. The second side frames 117 are both inverted triangular frame structures and are both arranged perpendicularly to the second vertical frame 115 and the bottom frame 116, so that the size of the main frame 1 in the second horizontal direction gradually decreases from bottom to top. The bottom frame 116 is used for installation and fixation to the mounting base, and the second vertical frame 115 is used to connect the circulating lifting device 2 and the vehicle platform assembly 3.

[0086] Furthermore, in one specific example, the electric vehicle automated parking garage 100 may include at least two circulating lifting devices 2, for example... Figure 11 In the example, at least two circulating lifting devices 2 are spaced apart in the first horizontal direction, and each circulating lifting device 2 is provided with multiple vehicle platform assemblies 3, thereby further increasing the number of electric vehicles that can be accommodated.

[0087] Furthermore, in a specific example, such as Figure 11 In the example shown, each circulating lifting device 2 is connected to at least ten vehicle platform assemblies 3 to further increase the transport efficiency of a single circulating lifting device 2. For example, in... Figure 11 and Figure 21 In the example, the main frame 1 can be set to have a dimension of 4.5m and a height of 11.5m in the first horizontal direction. The main frame 1 is mainly made of high-strength steel welded together. The main frame 1 can be equipped with two circulating lifting devices 2 arranged side by side. Each circulating lifting device 2 is connected to ten vehicle platform assemblies 3. The whole can accommodate at least twenty electric vehicles 5 at the same time.

[0088] Furthermore, in a specific example, the charging device 33 of the vehicle platform assembly 3 is communicatively connected to the controller 4. When the electric vehicle 5 is parked on the vehicle platform assembly 3, the electric vehicle 5 can be electrically connected to the charging device 33 (either directly or via a charging cable) to replenish the electric vehicle 5's power under the control of the controller 4.

[0089] In practical applications, controller 4 can be a PLC controller, which can be installed on the main frame 1 or the circulating lifting device 2, or a separate operating console can be set at the bottom or side of the main frame 1, with controller 4 built into the operating console. When an operating console is set up, control commands can be input through the console to facilitate vehicle storage and retrieval. The communication connection between controller 4 and the circulating lifting device 2, charging device 33, and locking device 32 can be a wired communication connection or a wireless communication connection, such as WIFI or 4G / 5G communication connection. The specific configuration can be determined according to actual usage needs and will not be elaborated further here.

[0090] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
