[0046] The vehicle loading plate assembly in this application is used to carry electric vehicles and can be applied to electric vehicle parking equipment, such as 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 following embodiments, for the convenience of description, the transverse direction of the vehicle loading plate assembly is used as the first horizontal direction, the longitudinal direction of the vehicle loading plate assembly is used as the second horizontal direction, and the height direction is used as the third direction; wherein, the transverse and longitudinal directions of the vehicle loading plate assembly are consistent with the transverse and longitudinal directions of the electric vehicle carried, and will not be repeated below.

[0048] Some embodiments of the vehicle loading plate assembly and electric vehicle multi-story parking garage provided by the present application are described below with reference to the accompanying drawings.

[0049] In the embodiment of the first aspect of the present application, a vehicle loading plate assembly 3 is provided, such as Figure 1 、 Figure 2 As shown, the vehicle loading plate assembly 3 includes a vehicle loading plate 31 and a vehicle locking device 32. The vehicle loading plate 31 serves as a supporting platform for the electric vehicle 5, and its top surface can support the electric vehicle 5. At one end of the vehicle loading plate 31, there is a mounting structure 3121 that can be connected to a lifting device. When the vehicle loading plate assembly 3 is applied to an electric vehicle multi-story parking device, it can be connected and installed with the lifting device through the mounting structure 3121, so that the vehicle loading plate 31 can move up and down with the lifting device. A vehicle locking device 32 is provided on the vehicle loading plate 31, which is used to lock the wheels 51 of the electric vehicle 5 to enable the locking operation, and at the same time, it can enable the electric vehicle 5 to remain stable on the vehicle loading plate 31, so that it can move up and down accordingly with the vehicle loading plate 31. The locking device 32 includes a movable portion 320 and a fixed portion 322; the fixed portion 322 is fixedly connected to the vehicle loading plate 31, the movable portion 320 and the fixed portion 322 are correspondingly arranged, and at least part of the movable portion 320 can be flipped and horizontally slid relative to the vehicle loading plate 31 to adjust the posture of the movable portion 320 and the distance between the movable portion 320 and the fixed portion 322; the movable portion 320 has a first rotation angle position and a second rotation angle position. When the movable portion 320 is in the first rotation angle position, as shown in FIG. Figure 3 In the example, the wheel 51 of the electric vehicle 5 can move to the movable portion 320, and the movable portion 320 can be flipped to the second rotation angle position so that the wheel 51 moves in the direction close to the fixed portion 322. At the same time, the movable portion 320 is connected to the vehicle loading plate 31, so that the wheel 51 is clamped by the movable portion 320 and the fixed portion 322. Figure 4In the state shown in FIG, the wheel 51 is locked.

[0050] When using, such as Figure 3 and Figure 4 In the example, in the initial state, the movable portion 320 is located at the first corner position. By pushing the electric vehicle 5 onto the vehicle loading plate 31, the front wheel of the electric vehicle 5 is pressed against the movable portion 320, and the pressure of the wheel 51 is used to flip the movable portion 320 from the first corner position to the second corner position. At the same time, the movable portion 320 is connected to the vehicle loading plate 31, and the front and rear ends of the wheel 51 are respectively in contact with the fixed portion 322 and the movable portion 320, and are clamped. According to the size of the wheel 51, the movable portion 320 can slide horizontally relative to the vehicle loading plate 31 so that the spacing between the movable portion 320 and the fixed portion 322 is adapted to the size of the wheel 51, ensuring that the front and rear ends of the wheel 51 are respectively in contact with the fixed portion 322 and the movable portion 320, thereby achieving the vehicle locking operation. When the vehicle needs to be retrieved, the movable portion 320 and the vehicle loading plate 31 are unlocked, thereby releasing the clamping state of the wheel 51. The electric vehicle 5 can be pushed away from the fixed portion 322, and the wheel 51 can be driven out of the movable portion 320 in the opposite direction to perform the corresponding vehicle retrieval operation.

[0051] It should be noted that the connection between the movable portion 320 and the vehicle loading plate 31 at the second corner position is a detachable connection, including but not limited to a snap connection or a magnetic connection. In addition, in actual application, the movable portion 320 and the fixed portion 322 can be configured to have a shape that is compatible with the wheel 51 to facilitate clamping of the wheel 51.

[0052] The vehicle loading plate assembly 3 in this embodiment simplifies the structure and locking operation of the vehicle locking device 32 through structural optimization and improvement, can realize automatic vehicle locking, and can adaptively adjust the position and posture of the movable part 320 according to the size of the wheel 51. It has stronger versatility and can adapt to electric vehicles 5 with wheels 51 of different sizes. When used in electric vehicle parking equipment, there is no need to equip different models of electric vehicles with different locking devices 32. The scope of application is wider, which is conducive to reducing equipment costs and operating costs and is convenient for promotion and application.

[0053] In a further embodiment of the present application, Figure 5 、 Figure 6As shown, the movable part 320 and the fixed part 322 of the locking device 32 are arranged relative 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. In the first horizontal direction, the two clamping arms 321 are arranged relative to each other; the two clamping arms 321 are rotatably connected to the vehicle loading plate 31 to form a lever-like structure, so that the clamping arms 321 can be flipped in a vertical plane relative to the vehicle loading plate 31; each clamping arm 321 is provided with a plurality of bearing plates 3213, and the bearing plates 3213 on the two clamping arms 321 are arranged correspondingly, 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 play a bearing role. Among them, the rotation axes of the two clamping arms 321 are in a mutually intersecting state and form a first angle a toward the side of the fixed part 322. The angle range of the first angle a is 150° to 170°, as shown in FIG. Figure 6 In the example, preferably, the first angle a can be 150°, 155°, 160°, 165°, or 170°; when the two clamping arms 321 are flipped from the first rotation angle position to the second rotation angle position, the distance between the two supporting plates 3213 arranged opposite to each other in the first horizontal direction is reduced, so that the two sides of the wheel 51 can be clamped in the width direction of the wheel 51 (i.e., the first horizontal direction), so as to limit and fix the wheel 51, thereby further enhancing the stability of the locked vehicle.

[0054] Further, if Figures 5 to 7 As shown, the clamping arm 321 of the movable portion 320 specifically includes a first clamping portion 3211 and a second clamping portion 3212 connected to each other. In the second horizontal direction, the connection between the first clamping portion 3211 and the second clamping portion 3212 is the rotation center position of the clamping arm 321, the first clamping portion 3211 is located on the side where the rotation center is away from the fixed portion 322, and the second clamping portion 3212 is located on the side where the rotation center is toward the fixed portion 322; a second angle b is formed between the first clamping portion 3211 and the second clamping portion 3212 in the vertical plane, the second angle b is toward the top of the vehicle loading plate 31, and the angle range of the second angle b is 90° to 120°, as shown in FIG. Figure 8 In the example, preferably, the second angle b can be 90°, 100°, 110°, or 120°. When the clamping arm 321 is in the first rotational angle position, the first clamping portion 3211 abuts against the vehicle loading plate 31, and the second clamping portion 3212 tilts upward. After the wheel 51 enters the load-bearing range of the clamping arm 321, the clamping arm 321 flips from the first rotational angle position to the second rotational angle position. At this time, the second clamping portion 3212 abuts against the vehicle loading plate 31, and the first clamping portion 3211 tilts upward. The first clamping portion 3211 is located at the rear side of the wheel 51 and, together with the fixing portion 322, clamps the wheel 51 from both the front and rear directions to secure the wheel 51.

[0055] Specifically, if Figures 5 to 7 In the example, a supporting plate 3213 is provided on the first clamping portion 3211 and the second clamping portion 3212 of each clamping arm 321, and in the first horizontal direction, the supporting plates 3213 on the two first clamping portions 3211 are arranged opposite to each other, and the supporting plates 3213 on the two second clamping portions 3212 are arranged opposite to each other. Each supporting plate 3213 includes a supporting side plate 32132 and a supporting bottom plate 32131 that are connected to each other. The supporting side plate 32132 is connected to the side of the supporting bottom plate 32131 away from the other supporting plate 3213 in the first horizontal direction, that is, the supporting side plates 32132 on the corresponding two supporting plates 3213 are respectively located close to the outer side of the corresponding supporting bottom plate 32131; at the same time, the side of the supporting bottom plate 32131 away from the corresponding supporting side plate 32132 has a plurality of tooth plate structures 32133, and the plurality of tooth plate structures 32133 are spaced apart in the second horizontal direction, and the tooth plate structures 32133 on the corresponding two supporting plates 3213 are cross-arranged to make up for the gap between the two supporting bottom plates 32131. When the wheel 51 enters the supporting plate 3213, the two supporting plates 3213 and the multiple cross-arranged tooth plate structures 32133 provide support for the bottom of the wheel 51. Simultaneously, the two opposing supporting side plates 32132 limit the sides of the wheel 51. After the clamping arms 321 rotate from the first angle position to the second angle position, the lateral distance between the two clamping arms 321 decreases, thereby reducing the distance between the two corresponding supporting side plates 32132, thereby clamping the wheel 51 from both sides.

[0056] Furthermore, in a specific example, Figure 7 In the example shown in FIG, the supporting side plates 32132 of each supporting plate 3213 are tilted in the first horizontal direction, away from the corresponding supporting plate 3213, so that the two corresponding supporting plates 3213 cooperate with each other to form a trumpet-shaped opening structure. Specifically, the spacing between the two cooperating supporting 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 be directly engaged between the two supporting side plates 32132 without contacting the supporting base plate 32131. This can also lock the wheel 51, thereby further expanding the adaptability range of the locking device 32 to wheel 51 sizes. In each supporting plate 3213, a third angle c is formed between the supporting side plate 32132 and the supporting bottom plate 32131. The third angle c is facing away from the vehicle-carrying plate 31, and the angle range of the third angle c is 120° to 150°. Preferably, the third angle c can be 120°, 130°, 140°, or 150°.

[0057] Furthermore, in a specific example, Figure 1 and Figure 5 In the example, a guide groove 3111 is provided on the top surface of the vehicle loading plate 31. The guide groove 3111 is recessed downward and is provided corresponding to the movable portion 320 in the second horizontal direction. The guide groove 3111 extends along the second horizontal direction and extends to the bottom of the movable portion 320. Accordingly, when the movable portion 320 is in the first corner position, the bottom of the first clamping portion 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 portion 3211 of the movable portion 320 along the guide groove 3111. In addition, the guide groove 3111 can also play a lateral limiting role on the wheel 51 of the electric vehicle 5, preventing the movement trajectory of the wheel 51 from being deviated and difficult to accurately dock with the supporting plate 3213 of the movable portion 320, which is conducive to improving the convenience of the vehicle locking operation. Preferably, as Figure 5 In the example, the two side walls of the guide groove 3111 can be set as a slope structure, and the inclination direction is consistent with the inclination direction of the two corresponding load-bearing side plates 32132 to facilitate the wheel 51 to enter the guide groove 3111.

[0058] Furthermore, in a specific example, Figure 7 In the example shown, the tooth plate structure 32133 of each support plate 3213 extends from the edge of the support base 32131 toward the opposing support plate 3213, and at least a portion of the tooth plate structure 32133 is tilted upward relative to the support base 32131. When the clamping arms 321 rotate from the first angle position to the second angle position, the lateral spacing between the two clamping arms 321 decreases, and the lateral spacing between the support plates 3213 also decreases accordingly. The tooth plate structure 32133 of each support plate 3213 moves closer to the other support plate 3213, and the upwardly positioned tooth plate structure 32133 prevents collision or interference with the other support plate 3213.

[0059] Furthermore, in a specific example, Figure 5 、 Figure 9 、 Figure 10As shown, the second clamping portion 3212 of the clamping arm 321 is provided with a first connecting structure 3214 on the side facing the vehicle loading plate, and accordingly, a second connecting structure 3112 is provided at the corresponding position on the vehicle loading plate. The first connecting structure 3214 and the second connecting structure 3112 are electromagnetic structures, and the magnetic poles are in opposite directions. When the second clamping portion 3212 is flipped to the second corner position, the first connecting structure 3214 can be adsorbed and connected with the second connecting structure 3112 to keep the second clamping portion 3212 at the second corner position to keep the wheel 51 in a locked state; when unlocking is required, the electromagnetic structure can be powered off to eliminate the magnetic attraction force, and the clamping arm 321 can be flipped in the opposite direction to perform the vehicle retrieval operation. Among them, a torsion spring 3216 is sleeved on the rotating shaft 3215 of the clamping arm 321, and the torsion spring 3216 is respectively in contact with the second clamping part 3212 and the vehicle loading plate. When the second clamping part 3212 flips to the second rotation angle position, the torsion spring 3216 is twisted and produces a movement tendency to restore to its original shape; when the first connecting structure 3214 is separated from the second connecting structure 3112, the clamping arm 321 can flip to the first rotation angle position under the action of the torsion force of the torsion spring 3216 to achieve automatic reset.

[0060] In a further embodiment of the present application, Figure 1 、 Figure 8 and Figure 9As shown, the top surface of the vehicle loading plate 31 is provided with a slide groove 3113 extending along the second horizontal direction. The slide groove 3113 is arranged corresponding to the fixed portion 322 to allow the movable portion 320 to slide. Accordingly, the vehicle locking device 32 also includes a slide 323 and a tension spring 324. The slide 323 is slidably connected to the slide groove 3113. The movable portion 320 is disposed on the slide 323 and fixedly connected to the slide 323, so that the movable portion 320 can slide along the second horizontal direction as a whole with the slide 323, thereby adjusting the distance between the movable portion 320 and the fixed portion 322 to accommodate wheels 51 of different sizes. When the wheel 51 is in the second rotation position, the first clamping portion 3211 of the clamping arm 321 abuts against the rear end of the wheel 51, and the wheel 51 is pressed against the second clamping portion 3212 by the first clamping portion 3211 and the rear end of the wheel 51. When the wheel 51 is separated from the movable portion 320 , the movable portion 320 and the sliding bracket 323 can be restored under the tension of the tension spring 324 .

[0061] It should be noted that the number of chutes 3113 can be as follows: Figure 9 The two shown in FIG, correspondingly, the two sides of the slide 323 are respectively slidably connected with the two chute 3113. Of course, in actual application, the number of the chute 3113 can also be adjusted according to actual conditions, for example, one or more than two numbers can also be set.

[0062] Furthermore, in a specific example, Figure 2 、 Figure 5 and Figure 9In the example, the vehicle locking device 32 further includes a locking hook mechanism 325. In the first horizontal direction, the locking hook mechanism 325 is disposed to the side of the second clamping portion 3212. The locking hook mechanism 325 is rotatably connected to the vehicle loading plate 31 and can rotate relative to the vehicle loading plate 31. Correspondingly, the second clamping portion 3212 is provided with a plurality of locking hole structures 32121, and the locking hole structures 32121 are spaced apart along the extension direction of the second clamping portion 3212. When the clamping arm 321 is at the second rotation angle 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 manually operated, or a corresponding drive mechanism can be provided to drive the locking hook mechanism 325 to rotate.

[0063] Furthermore, in a specific example, Figure 10 In the example, the loading plate 31 specifically includes a loading plate body 311 and a connecting frame 312. The loading plate body 311 is horizontally arranged to carry the electric vehicle 5. The loading plate body 311 is an overall rectangular plate structure, with its length aligned with the second horizontal direction and its width aligned with the first horizontal direction. The connecting frame is vertically arranged and connected to one end of the loading plate body 311 in the second horizontal direction. The mounting structure 3121 is provided on the connecting frame 312 to facilitate connection and installation with the lifting device. A fixed portion 322 is provided on the side of the connecting frame 312 facing the loading plate body 311. The movable portion 320 is provided on the loading plate body 311 and is opposite to the fixed portion 322. The fixed portion 322 has a fixing groove 3221 on the side facing the movable portion 320 for accommodating the wheel 51. In the first horizontal direction, the two sidewalls of the fixing groove 3221 are inclined toward each other, forming a trumpet-like cross-sectional shape to accommodate wheels 51 of varying widths. Preferably, the vehicle loading plate body 311 and the connecting frame 312 are made of high-strength aluminum alloy. Corresponding reinforcing plates or reinforcing rods can also be provided at the connection between the connecting frame 312 and the vehicle loading plate body 311 to improve the overall connection strength of the vehicle loading plate 31.

[0064] Furthermore, in a specific example, Figure 10In the example shown in FIG, a charging device 33 is also provided on the vehicle loading plate 31. The electric vehicle 5 carried on the vehicle loading plate 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, on the connecting frame 312 or on the vehicle loading plate body 311. The charging device 33 can be located entirely on the vehicle loading plate 31, or only a charging port or adapter can be provided on the vehicle loading plate 31 and connected to an external power source via a corresponding cable.

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

[0066] In an embodiment of the second aspect of the present application, a three-dimensional parking garage 100 for electric vehicles is provided. Figure 1 、 Figure 11 、 Figure 12 As shown, the electric vehicle multi-story parking garage 100 includes a main frame 1, a circulating lifting device 2, a vehicle loading plate assembly 3 in any of the above-mentioned embodiments, and a controller 4. The main frame 1 serves as a mounting base, which is used to be mounted and fixed to the mounting base surface, and can support and fix the circulating lifting device 2, the vehicle loading plate assembly 3, and the controller 4; the main frame 1 is arranged along the height direction as a whole, and a circulating track 12 is provided on the main frame 1, and 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, and the circulating lifting device 2 is arranged along the height direction and corresponds to the circulating track 12; the circulating lifting device 2 has a motion mechanism, and the motion mechanism can perform a cyclic motion along the circulating track 12; a plurality of vehicle loading plate assemblies 3 are connected to the motion mechanism at intervals, and the vehicle loading plate assembly 3 is used to park the electric vehicle 5, and the vehicle locking device 32 on the vehicle loading plate assembly 3 can lock the wheels 51 of the electric vehicle to achieve vehicle locking. The controller 4 is connected in communication with the circulating lifting device 2 to control the circulation lifting device 2. When the motion mechanism moves in a circular motion along the circulating track 12, it drives multiple vehicle loading plate assemblies 3 to move synchronously, so that multiple vehicle loading plate assemblies 3 can realize lifting and lowering motion in the vertical plane. When any vehicle loading plate assembly 3 moves to the lowest end, the user can park or pick up the vehicle on the vehicle loading plate assembly 3.

[0067] It is understandable that existing electric vehicle parking garages typically use a conventional vertical lift mechanism combined with a horizontal motion mechanism to achieve three-dimensional parking. The lift mechanism requires a fixed vertical lift channel. After reaching the designated level, a horizontal motion mechanism is also required to transport the vehicle carrier to the designated location or from the designated location to the lift 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 will be too long, and increasing the number of lift mechanisms will increase equipment costs and take up more space. Therefore, existing three-dimensional parking garages generally adopt a small design (for example, two or three floors), which can accommodate a limited number of parking spaces.

[0068] The electric vehicle multi-story parking garage 100 in this embodiment, through structural improvement and optimization, adopts a circulating lifting device 2 to perform circulating motion in a three-dimensional space, which can greatly improve the transportation efficiency of electric vehicles and significantly shorten the time required for parking and picking up vehicles. Compared with existing parking garages, it can provide more parking spaces and is suitable for use in large and medium-sized parking lots. In addition, it does not require the configuration of a corresponding horizontal transportation mechanism, has a relatively simple structure, and has a relatively low equipment cost, which is conducive to promotion and application.

[0069] It should be noted that the main frame 1 is not limited to the rectangular frame structure shown in the figure, and can also adopt frame structures of other shapes according to the use requirements. The movement mechanism of the circulating lifting device 2 can rotate clockwise or counterclockwise according to the needs.

[0070] In a further embodiment of the present application, Figure 13 、 Figure 14 and Figure 15As shown, in the electric vehicle multi-story parking garage 100, the circulating lifting device 2 includes a slide rail frame 21, a first sprocket assembly 22, and a driving mechanism 23. The slide rail frame 21 is connected to the main frame 1 and is arranged in the vertical direction. 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 arranged at both ends of the slide rail frame 21 in the height direction, and there is a certain gap between them and the slide rail frame 21 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 engagement, and the first transmission chain 223 slides with the slide rail structure 211 on both sides of the slide frame. The drive mechanism 23 is mounted on the main frame 1 at a position corresponding to the first driving gear 221, and is in transmission connection with the first driving gear 221 to drive the first driving gear 221 to rotate, thereby driving the first transmission chain 223 to move along the circulating track 12. The first transmission chain 223 forms the motion mechanism of the circulating lifting device 2, and its motion trajectory is adapted to the circulating track 12; the vehicle loading plate 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 so as to be staggered with the main frame 1. When the first transmission chain 223 moves along the circulating track 12 driven by the first driving gear 221, the multiple vehicle loading plate assemblies 3 move synchronously with the first transmission chain 223, thereby achieving the lifting and lowering operation of the vehicle loading plate assembly 3.

[0071] The slide rail frame 21 is provided to allow the first transmission chain 223 to form a sliding fit with the slide rail, thereby guiding and limiting the first transmission chain 223, preventing the first transmission chain 223 from shaking during movement, thereby improving movement stability. In addition, compared to synchronous belt drive, the chain drive method used in this embodiment is less prone to slippage, has a stronger load-bearing capacity, and can carry a larger number of electric vehicles 5.

[0072] Further, if Figure 13 and Figure 15As shown, the first driving 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 driving mechanism 23 is arranged corresponding to the first driving gear 221, so that it can be staggered with 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 the second driving gear 2321 and the second driven gear 2322, respectively. The drive motor 231 is in transmission connection with the second driving gear 2321 to drive the second driving gear 2321 to rotate. 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 generate corresponding movement. The second driving gear 2321 and the drive motor 231 are both located below the second driven gear 2322 to utilize the space below it for reasonable spatial arrangement and avoid occupying excessive space in the height direction.

[0073] It should be noted that if 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 rotational speed of the second driven gear 2322 through the transmission ratio to achieve a deceleration effect; alternatively, a drive motor 231 with a deceleration function, such as a reduction motor, can be used to reduce the output speed, thereby meeting the movement speed requirement of the first transmission chain 223.

[0074] Further, if Figure 16 、 Figure 17 and Figure 18In the example shown in FIG, a first transmission chain 223 is connected to a plurality of connectors 224, which are spaced apart on the first transmission chain 223 and each connector 224 corresponds to one of the vehicle loading plate assemblies 3. Accordingly, each vehicle loading plate assembly 3 is connected to a balancing guide wheel assembly 24, which is rotatably connected to a corresponding connector 224, so that the vehicle loading plate assembly 3 is connected to the connector 224 and can circulate along with the first transmission chain 223. At least two guide wheels in each balancing guide wheel assembly 24 form a rolling engagement with the circulating track 12, so that the vehicle loading plate assembly 3 can always remain horizontal during the cyclic motion along with the first transmission chain 223, thereby preventing the electric vehicle 5 on the vehicle loading plate assembly 3 from tipping over. It can be understood that the connecting member 224 is fixedly connected to the first transmission chain 223. As the first transmission chain 223 moves, the orientation of the connecting member 224 will inevitably change, and the vehicle loading plate assembly 3 forms a rotational connection with the connecting member 224 through the balancing guide wheel assembly 24. The connecting member 224 and the vehicle loading plate assembly 3 can rotate relative to each other, and the cooperation of the guide wheel and the circulating track 12 keeps the vehicle loading plate assembly 3 in a horizontal state.

[0075] Further, if Figure 17 、 Figure 19 As shown, the balancing guide wheel assembly 24 includes a balancing shaft 241, a first balancing mechanism 242, and a second balancing mechanism 243. The balancing shaft 241 is arranged along the second horizontal direction and is rotatably inserted into the connecting member 224. One end of the balancing shaft 241 is fixedly connected to the vehicle carrier assembly 3, and the first balancing mechanism 242 and the second balancing mechanism 243 are connected to the balancing shaft 241 near the other end. The first balancing mechanism 242 is arranged in the vertical direction and is connected to a first balancing guide wheel 2421 at each end. The rotation axis of the first balancing guide wheel 2421 is arranged along the second horizontal direction. The second balancing mechanism 243 is arranged in the first horizontal direction and is connected to a second balancing guide wheel 2431 at each end. The rotation axis of the second balancing guide wheel 2431 is arranged along the second horizontal direction. The first balancing mechanism 242 and the second balancing mechanism 243 form a cross 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 arcuate segments and two curved segments. The two curved segments are arranged opposite each other in the height direction. The two linear segments each extend in the height direction and are sequentially connected to the two curved segments, forming a closed motion trajectory connected end to end. The circulating 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 sequentially passes through the linear segments and the curved segments during the movement of the first transmission chain 223. That is, the connecting member 224 alternates between the linear segments and the curved segments during the circulation process. Among them, when the connecting member 224 is in the motion state of the straight motion section, the two first balance guide wheels 2421 of the first balance mechanism 242 form a rolling fit with the circulating track 12, and the force of the circulating track 12 on the two first balance guide wheels 2421 makes the carrier plate assembly 3 always in a horizontal state during the straight motion process; when the connecting member 224 is in the motion state of the arc motion section, a corresponding first balance guide wheel 2421 in the first balance mechanism 242 and a corresponding second balance guide wheel 2431 in the second balance mechanism 243 form a rolling fit with the circulating track 12, so as to utilize the force of the circulating track 12 on the first balance guide wheel 2421 and the second balance guide wheel 2431, so that the carrier plate assembly 3 is always in a horizontal state during the arc motion process.

[0077] Furthermore, in a specific example, Figure 15 、 Figure 17 、 Figure 18As shown, the circulating track 12 specifically includes two first curved guide rails 121, two linear guide rails 122, two second curved guide rails 123, and two third curved guide rails 124. The two first curved guide rails 121 are arranged relative to each other in the height direction, and the two linear guide rails 122 are in the same vertical plane as the two first curved guide rails 121 and are arranged between the two first curved guide rails 121 in the height direction. The two ends of one linear guide rail 122 are respectively connected to one end of the two first curved guide rails 121, and the two ends of the other linear guide rail 122 are respectively connected to the other end of the two first curved guide rails 121, thereby forming a closed guide rail structure to correspond to the motion trajectory of the first transmission chain 223. In the first horizontal direction, with the rotation center of the first sprocket assembly 22 as the critical point, the first curved guide rail 121 specifically includes two arc segments that are connected to each other and located on both sides of the critical point. Correspondingly, the second curved guide rail 123, the third curved guide rail 124 and the first curved guide rail 121 are arranged in sequence in the second horizontal direction, that is, each first curved guide rail 121 is arranged corresponding to a second curved guide rail 123 and a third curved guide rail 124; and in the first horizontal direction, the second curved guide rail 123 is located on one side of the critical point and corresponds to one of the curved segments of the first curved guide rail 121, and the third curved guide rail 124 is located on the other side of the critical point and corresponds to the other curved segment of the first curved guide rail 121; the second curved guide rail 123 smoothly transitions with one of the linear guide rails 122, and the third curved guide rail 124 smoothly transitions with the other linear guide 122.

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

[0079] Through the above-mentioned arrangement, no matter whether the connecting member 224 moves in the straight motion section or the arc motion section, the carrier plate assembly 3 can be kept in a horizontal state, and in the process of entering the arc motion section from the straight motion section or from the arc motion section into the straight motion section, a smooth transition can be maintained, thereby enhancing the movement stability of the moving parts and the carrier plate assembly 3.

[0080] Among them, such as Figure 18 In the example, the connecting member 224 can specifically adopt a block or shell structure, and is clamped and docked with both sides of the chain of the first transmission chain 223, and is connected and fixed by pins or bolts.

[0081] Furthermore, in a specific example, Figure 15 、 Figure 16 as well as Figure 18 、 Figure 19 In the example, the main frame 1 is further provided with a matching frame 13. The matching frame 13 is arranged in the height direction and has an assembly space 131 extending along the second horizontal direction. The slide rail frame 21 and the first sprocket assembly 22 are arranged within the assembly space 131 of the matching frame 13, and the inner contour of the assembly space 131 is adapted to the motion trajectory of the first transmission chain 223. Correspondingly, a plurality of second guide wheels 2241 are provided on either side of the connecting member 224 in the second horizontal direction, with the rotation axis of the second guide wheels 2241 located within the vertical plane. On either side of the connecting member 224 in the second horizontal direction, some of the second guide wheels 2241 are in rolling engagement with the slide rail frame 21 or the first sprocket assembly 22, while others are in rolling engagement with the matching frame 13.

[0082] Specifically, if Figure 18 and Figure 19 In the example, a plurality of second guide wheels 2241 (e.g., six as shown) are provided on each side of the connecting member 224 in the second horizontal direction. The plurality of second guide wheels 2241 are arranged side by side, and a portion of the second guide wheels 2241 extends toward the first sprocket mechanism, and another portion of the second guide wheels 2241 extends toward the matching frame 13. During the circular motion of the connecting member 224 along with the first transmission chain 223, the direction of the rotation axis of the second guide wheel 2241 changes, but is always in the vertical plane, for example Figures 18 to 20 When the moving part moves with the first transmission chain 223, the second guide wheel 2241 extending toward the matching frame 13 always rolls with the side surfaces of the matching frame 13. When the moving part is in a linear motion section, the second guide wheel 2241 extending toward the first sprocket assembly 22 rolls with the side surfaces of the slide rail frame 21. When the moving part is in an arcuate motion section, the second guide wheel 2241 extending toward the first sprocket assembly 22 rolls with the side surfaces of the corresponding first driving gear 221 or first driven gear 222.

[0083] By setting the second guide wheel 2241, the connecting member 224 can be prevented from pitching and swinging, so that the connecting member 224 is always in a vertical state, thereby preventing the vehicle loading plate assembly 3 connected to the connecting member 224 from swinging, and further enhancing the stability of the vehicle loading plate assembly 3.

[0084] In a further embodiment of the present application, Figure 13 、 Figure 14 As shown, in a specific example, the main frame 1 adopts a rectangular parallelepiped frame structure, specifically including a rectangular first vertical frame 111, a first side frame 112, and a top frame 113. There are two first side frames 112, which are respectively connected to the two sides of the first vertical frame 111 in the first horizontal direction and are arranged perpendicular to the first vertical frame 111. The top frame 113 is connected to the top of the first vertical frame 111 and the first side frame 112 and is arranged along the horizontal plane to form a rectangular parallelepiped frame structure. In the second horizontal direction, the other side opposite the first vertical frame 111 is an open structure to facilitate the installation of the circulating lifting device 2 and the vehicle loading plate assembly 3. The bottom of the first vertical frame 111 and the first side frame 112 can be installed and fixed to the installation base surface; corresponding baffles can also be provided on the top frame 113 as needed.

[0085] In a further embodiment of the present application, Figure 11 and Figure 21 In another specific example, the main frame 1 adopts an inverted triangle stereoscopic 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 perpendicular 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 arranged at intervals in the first horizontal direction and are located on the two side edges of the second vertical frame 115. The second side frames 117 are both inverted triangle frame structures and are arranged perpendicular 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 to be installed and fixed to the installation base, and the second vertical frame 115 is used to connect the circulating lifting device 2 and the vehicle loading plate assembly 3.

[0086] Furthermore, in a specific example, the electric vehicle 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 a plurality of vehicle-carrying plate assemblies 3, thereby further increasing the number of electric vehicles that can be accommodated.

[0087] Furthermore, in a specific example, Figure 11 In the example, each circulating lifting device 2 is connected with at least ten vehicle-carrying plate assemblies 3 to further increase the transport efficiency of a single circulating lifting device 2. Figure 11 and Figure 21 In the example, the main frame 1 can be set to have a size of 4.5m in the first horizontal direction and a height of 11.5m. The main frame 1 is mainly made of high-strength steel welded together; the main frame 1 can arrange two circulating lifting devices 2 side by side, and each circulating lifting device 2 is connected to ten vehicle-carrying plate assemblies 3, and 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 loading plate assembly 3 is communicatively connected to the controller 4. When the electric vehicle 5 is parked on the vehicle loading plate assembly 3, the electric vehicle 5 can be electrically connected to the charging device 33 (directly or through a charging cable) to replenish the power of the electric vehicle 5 under the control of the controller 4.

[0089] In actual use, controller 4 can be a PLC controller 4, which can be installed on the main frame 1 or the circulating lifting device 2, or a separate operating console can be installed at the bottom or next to the main frame 1, with controller 4 built into the console. When an operating console is provided, a user can input control commands through the console to facilitate vehicle storage and retrieval operations. The communication connection between controller 4 and the circulating lifting device 2, charging device 33, and vehicle locking device 32 can be a wired communication connection or a wireless communication connection, such as a WiFi or 4G / 5G communication connection. The specific configuration can be based on actual usage needs and will not be detailed here.

[0090] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
