Description

Technical Field

[0001] This application relates to the field of electric vehicle parking equipment technology, specifically to an electric vehicle automated parking garage. Background Technology

[0002] Currently, electric vehicles (including but not limited to electric bicycles and electric motorcycles) are a common mode of transportation. Common electric vehicle parking garages are typically floor-level, but due to their large land area requirements and low space utilization, the number of electric vehicles they can accommodate is limited. To address this, some manufacturers have provided multi-level parking garages that utilize vertical space for electric vehicle parking, employing vertical lifts in conjunction with horizontal transport mechanisms to move the vehicles. However, these multi-level parking garages still have some drawbacks. For example, the transport system is relatively complex and costly, and the number of vehicles transported at a time (usually one) is limited, resulting in longer parking and retrieval times and lower operational efficiency. They are also inconvenient to use when there are many parking spaces, limiting the expansion of the parking garage's capacity. Therefore, this type of parking garage is currently usually limited to small parking garages and is not conducive to widespread application. Utility Model Content

[0039] The electric vehicle multi-level parking garage in this application is used to park electric vehicles, including but not limited to electric bicycles and electric motorcycles; it utilizes a three-dimensional space to arrange multiple vehicle-carrying mechanisms to park multiple electric vehicles, and uses a circulating lifting device to drive the vehicle-carrying mechanisms to perform circulating lifting and lowering movements in a vertical plane to realize the transportation operation of electric vehicles.

[0040] In the embodiments described below, for ease of description, the lateral direction of the electric vehicle automated parking garage is taken as the first horizontal direction, the longitudinal direction of the electric vehicle automated parking garage is taken as the second horizontal direction, and the height direction is taken as the third horizontal direction. The lateral and longitudinal directions are based on the vehicle-carrying mechanism of the electric vehicle automated parking garage, that is, the lateral and longitudinal directions of the parked electric vehicles are taken as the lateral and longitudinal directions of the electric vehicle automated parking garage, respectively. This will not be elaborated further below.

[0041] The following describes some embodiments of the electric vehicle automated parking system provided in this application, with reference to the accompanying drawings.

[0042] An embodiment of this application provides an electric vehicle automated parking garage 100, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the electric vehicle automated parking garage 100 includes a main frame 1, a circulating lifting device 2, a vehicle carrying mechanism 3, and a controller 4. The main frame 1 serves as the mounting base, used for installation and fixation to the mounting surface, and supports and fixes the circulating lifting device 2, the vehicle carrying mechanism 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 mechanisms 3 are connected at intervals on the motion mechanism, and parking spaces are provided on the vehicle carrying mechanisms 3 for parking electric vehicles 5. The controller 4 is communicatively connected to the circulating lifting device 2 to control its operation. When the motion mechanism moves in a circular motion along the circular track 12, it drives multiple vehicle-carrying mechanisms 3 to move synchronously, so that the multiple vehicle-carrying mechanisms 3 can achieve lifting and lowering motion in the vertical plane. When any vehicle-carrying mechanism 3 moves to the bottom, the user can park or retrieve the vehicle from that vehicle-carrying mechanism 3.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] In further embodiments of this application, such as Figure 5 , Figure 6 and Figure 7As 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 is drively connected to the first drive gear 221 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 carrier mechanism 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 carrier mechanisms 3 move synchronously with the first transmission chain 223, realizing the lifting operation of the vehicle carrier mechanisms 3.

[0047] 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.

[0048] Furthermore, such as Figure 5 and Figure 7As 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. 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 through the second transmission chain 2323, it 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.

[0049] It should be noted that, as Figure 7 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.

[0050] Furthermore, such as Figure 8 , Figure 9 and Figure 10In the example, a plurality of connectors 224 are connected to the first transmission chain 223. The connectors 224 are spaced apart on the first transmission chain 223, and each connector 224 corresponds to one of the vehicle carrier mechanisms 3. Accordingly, each vehicle carrier mechanism 3 is connected to a balance guide wheel assembly 24, which is rotatably connected to a corresponding connector 224, so that the vehicle carrier mechanism 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 carrier mechanism 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 carrier mechanism 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 carrier 3 forms a rotational connection with the connector 224 through the balance guide wheel assembly 24. The connector 224 and the vehicle carrier 3 can rotate relative to each other, and the vehicle carrier 3 is kept horizontal under the cooperation of the guide wheel and the circulating track 12.

[0051] Furthermore, such as Figure 9 , Figure 10 , Figure 11 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 fixedly connected to the vehicle carrier mechanism 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.

[0052] 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 carrier 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 carrier 3 remains horizontal during the arc motion.

[0053] Furthermore, in a specific example, such as Figure 7 , Figures 9 to 11As 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.

[0054] 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 8 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.

[0055] With the above settings, the vehicle carrier 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 carrier 3.

[0056] Among them, such as Figure 11 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.

[0057] Furthermore, in a specific example, such as Figure 7 , Figure 8 as well as Figure 11 , Figure 12 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.

[0058] Specifically, such as Figure 11 and Figure 12 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 11 to 13 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.

[0059] By setting the second guide wheel 2241, the pitch swing of the connecting piece 224 can be prevented, and the connecting piece 224 can always be in a vertical state, thereby preventing the vehicle-carrying mechanism 3 connected to the connecting piece 224 from swinging, and further enhancing the stability of the vehicle-carrying mechanism 3.

[0060] In further embodiments of this application, such as Figure 5 , Figure 6 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-carrying mechanism 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.

[0061] In further embodiments of this application, such as Figure 1 and Figure 14 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 perpendicular to the bottom frame 116, meaning the second vertical frame 115 is arranged vertically, and the bottom frame 116 is arranged horizontally. The two second side frames 117 are spaced apart in the first horizontal direction and located on both sides of the second vertical frame 115. Both second side frames 117 are inverted triangular frame structures and are perpendicular to both the second vertical frame 115 and the bottom frame 116, causing the size of the main frame 1 in the second horizontal direction to gradually decrease 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-carrying mechanism 3.

[0062] Furthermore, in one specific example, the electric vehicle automated parking garage 100 may include at least two circulating lifting devices 2, for example... Figure 1 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 carrying mechanisms 3, thereby further increasing the number of electric vehicles that can be accommodated.

[0063] Furthermore, in a specific example, such as Figure 1 In the example shown, each circulating lifting device 2 is connected to at least ten vehicle-carrying mechanisms 3 to further increase the transport efficiency of a single circulating lifting device 2. For example, in... Figure 1 and Figure 14 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 carrying mechanisms 3. The vehicle carrying mechanisms 3 are specifically made of high-strength aluminum alloy. The whole can accommodate at least twenty electric vehicles 5 at the same time.

[0064] In a specific example, such as Figure 13 In the example, one end of the vehicle platform 31 of the vehicle carrier mechanism is connected to the connector, and the vehicle platform 31 is used to park the electric vehicle 5; guardrails 32 are also provided on both sides of the vehicle platform 31.

[0065] Furthermore, in a specific example, a charging device is provided on the vehicle carrier 3 for charging the electric vehicle 5; the charging device is communicatively connected to the controller 4, and when the electric vehicle 5 is parked on the vehicle carrier 3, the charging device can be electrically connected to the charging interface of the electric vehicle 5 (it can be directly connected or connected through a charging cable) to replenish the electric vehicle 5 under the control of the controller 4.

[0066] Furthermore, in a specific example, the vehicle-carrying mechanism 3 is also equipped with a locking device. When the electric vehicle 5 is parked on the vehicle-carrying mechanism 3, it can be locked to the electric vehicle 5 through the locking device. The locking device is connected to the controller 4 in communication so as to work under the control of the controller 4 to realize the function of fixing and preventing theft of the electric vehicle 5.

[0067] 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 next to the main frame 1, with controller 4 built into the operating console. When an operating console is used, 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, and locking device 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.

[0068] 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.
