Description

Electric vehicle charging device and stereoscopic parking garage Technical Field

[0001] The present invention relates to the technical field of charging of electric vehicles, and in particular to a charging device for an electric vehicle and a stereoscopic parking garage. Background Art

[0002] As an essential means of transportation, cars are increasingly common. To address the growing parking problem, various parking systems have emerged. Lifting and sliding parking garages utilize a lifting and sliding platform to access vehicles. Their high space utilization makes them widely used in high-traffic locations such as shopping malls, hospitals, office parks, and bus hubs.

[0003] In addition, as my country's automobile industry gradually transforms towards new energy vehicles, the types and number of electric vehicles are rapidly increasing, and the locations of their charging ports are also diverse. In order to take into account the charging needs of various models, existing charging piles are usually equipped with longer charging gun cables so that users can move the charging gun to any position in the parking space for charging. However, since the multi-story parking garage contains multiple parking spaces, the car loading tray needs to be frequently raised, lowered, and moved horizontally to meet the needs of parking and picking up the car. This long gun cable compatibility solution can easily cause the gun cable to become entangled with other gun cables in adjacent parking spaces, or other equipment such as the frame of the multi-story parking garage, resulting in damage or breakage of the gun cable during the raising, lowering, and moving of the car loading tray, and ultimately causing charging failures.

[0004] To overcome the aforementioned issues, various cable reel-based vehicle charging solutions have been proposed in the field. These solutions can release a corresponding length of cable based on the distance from the charging port and retract the cable promptly after charging is complete to avoid entanglement with other charging cables or adjacent equipment, and to meet the needs of charging vehicles in multiple parking spaces. However, with the continuous development of vehicle fast charging technology, the diameter of the charging cable has continued to increase, and its corresponding maximum bending radius has also continued to increase. This cable reel-based vehicle charging solution not only requires frequent bending of the charging cable, but also has the problem of a small bending radius in the center area. As a result, the cable is easily damaged or broken due to frequent and excessive bending, which shortens the service life of the charging cable.

[0005] In order to overcome the above-mentioned defects of the existing technology, the field urgently needs an improved vehicle charging solution, which can reduce the distance from the charging gun to the charging port and the required length of the active section of the charging cable, thereby avoiding charging failures caused by cable entanglement and improving the service life of the charging cable.

[0006] Summary of the Invention

[0007] The following is a brief summary of one or more aspects to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all conceivable aspects and is neither intended to identify key or critical elements of all aspects nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that will be provided later.

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides a charging device for an electric vehicle and a three-dimensional parking garage, which can fix the fixed section of the charging cable, raise the starting height of the movable section of the charging cable, and rotate and move the charging gun to the side where the charging port of the electric vehicle is located, shortening the distance from the charging gun to the charging interface, so as to reduce the length required for the movable section of the charging cable, thereby avoiding charging failures caused by cable entanglement and improving the service life of the charging cable.

[0009] Specifically, the charging device for the electric vehicle provided according to the first aspect of the present invention includes a power supply, a charging gun, a rotating support mechanism and a charging cable. The power supply is used to provide electrical energy. The charging gun is used to plug into the charging port of the electric vehicle to charge it.

The charging cable connects the power supply and the charging gun, and includes a fixed section and a movable section. The fixed section is fixed to the rotating support mechanism and extends along it to a preset first height. The movable section is detached from the rotating support mechanism from the first height to movably connect the charging gun.

[0010] Furthermore, the multi-story parking garage provided in accordance with the second aspect of the present invention includes M*N parking spaces, M*Ni vehicle loading trays, and at least one electric vehicle charging device as described above in accordance with the first aspect of the present invention.

[0024] The following specific embodiments illustrate the embodiments of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this embodiment. On the contrary, the purpose of introducing the invention in conjunction with the embodiment is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] Furthermore, the terms "upper," "lower," "left," "right," "top," "bottom," "horizontal," and "vertical" used in the following description should be understood to refer to the orientations depicted in that section and the accompanying drawings. These relative terms are used solely for convenience of description and do not necessarily imply that the devices described herein must be manufactured or operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0027] It will be understood that although the terms "first," "second," "third," etc. may be used herein to describe various components, regions, layers, and / or portions, these components, regions, layers, and / or portions should not be limited by these terms, and these terms are merely used to distinguish different components, regions, layers, and / or portions. Thus, a first component, region, layer, and / or portion discussed below may be referred to as a second component, region, layer, and / or portion without departing from some embodiments of the present invention.

[0028] As mentioned above, since the multi-story parking garage contains multiple parking spaces, the car loading pallets need to be frequently raised, lowered, and moved laterally to meet the needs of parking and retrieving cars. The conventional compatibility scheme of the long gun line can easily cause the gun line to become entangled with other gun lines in adjacent parking spaces, or other equipment such as the frame of the multi-story parking garage, thereby causing the gun line to be damaged or broken during the process of raising, lowering, and moving the car loading pallet, and ultimately causing charging failure.

[0029] Furthermore, although various cable reel-based vehicle charging solutions have been proposed in the art, which can release a corresponding length of cable based on the distance from the charging port and retract the cable promptly after charging is completed to avoid entanglement with other charging cables or adjacent equipment, and meet the needs of charging vehicles in multiple parking spaces, with the continuous development of vehicle fast charging technology, the diameter of the charging cable continues to increase, and its corresponding maximum bending radius also continues to increase. This cable reel-based vehicle charging solution not only requires frequent bending of the charging cable, but also has the problem of a small bending radius in the center area. Therefore, frequent and excessive bending of the cable can easily lead to damage and breakage, which shortens the service life of the charging cable.

[0030] In order to overcome the above-mentioned defects of the prior art, the present invention provides a charging device for an electric vehicle and a three-dimensional parking garage, which can fix the fixed section of the charging cable, raise the starting height of the movable section of the charging cable, and rotate and move the charging gun to the side where the charging port of the electric vehicle is located, shortening the distance from the charging gun to the charging interface, so as to reduce the length required for the movable section of the charging cable, thereby avoiding charging failures caused by cable entanglement and improving the service life of the charging cable.

[0031] First, please refer to FIG1 , which shows a schematic structural diagram of a charging device for an electric vehicle according to some embodiments of the present invention.

[0032] In the embodiment shown in Figure 1, the first aspect of the present invention provides a charging device for an electric vehicle, comprising a power supply, a charging gun 12, a rotating support mechanism, and a charging cable. The power supply, which can be either a DC power supply or an AC power supply, is integrated into the charging station 11 of the charging device to provide electrical energy to the electric vehicle via the charging cable and charging gun 12. The charging gun 12 is located at the end of the charging cable and is used to connect to the charging port of the electric vehicle to charge it.

[0033] The rotating support mechanism can be arranged behind the parking position to carry an idle charging gun 12 that is not inserted into the charging port, and rotate it to the side where the charging port of the electric vehicle is located (for example: the left or right side of the electric vehicle) to shorten its distance to the charging port of various types of electric vehicles, thereby reducing the length required for the active section of the charging cable.

[0034] The charging cable connects to the power source and the charging gun 12 at both ends, and is divided into a fixed section 141 and a movable section (i.e., the charging gun cable) 142. The fixed section 141 is fixed to the rotating support mechanism and extends along it to a predetermined first height, while the movable section 142 detaches from the rotating support mechanism at the first height to flexibly connect to the charging gun 12.

[0035] Furthermore, in some embodiments, the first height may be comparable to the height of the charging port of an electric vehicle. Specifically, technicians may determine the first height based on the height of the charging port of at least one charging vehicle. For example, technicians may count the heights of the charging ports of a variety of common charging vehicles on the market and determine the first height based on their maximum, minimum, or average values. For another example, for a charging device that focuses on serving a certain brand of vehicle, technicians may also assign a greater weight coefficient to the heights of the charging ports of several models of the brand and determine the first height by weighted summation.

[0036] In this way, by reasonably designing the first height of the active section of the charging cable away from the rotating support mechanism, the present invention can further shorten the distance from the idle charging gun to the charging port of the electric vehicle in the height direction, so as to further reduce the required length of the active section of the charging cable, thereby further reducing the risk of entanglement of the charging cable.

[0037] In addition, as shown in Figure 1, the above-mentioned rotating support mechanism may include a rotating shaft 131 and a rocker arm 132. The rotating shaft 131 can be vertically installed on the ground behind the parking position, the vertical storage frame, or the rear edge of the vehicle loading tray 151 located at the parking position to provide a driving force for horizontal rotation. The first end of the rocker arm 132 is connected to the rotating shaft 131, and the second end thereof is connected to the movable section 142 of the charging cable. Driven by the rotating shaft 131, the rocker arm 132 rotates clockwise or counterclockwise in the horizontal direction to rotate and move the charging gun 12 at the end of the movable section 142 to the side where the charging port of the electric vehicle is located.

[0038] Furthermore, in some embodiments, the second height of the rotating shaft 131 may be greater than the third height of the top of the electric vehicle. The second end of the rocker arm 132 may be provided with a charging gun holder 16, which is used to rotate horizontally at the second height under the drive of the rotating shaft 131 to rotate and move the charging gun 12 it carries to the side where the charging port of the electric vehicle is located, thereby avoiding collision with vehicles parked in the parking space or adjacent parking spaces during rotation. In addition, the movable section 142 of the charging cable can be detached from the rotating shaft 131 at the first height and flexibly connected to the charging gun carried by the charging gun holder 16, so that the user can plug the charging gun 12 into the charging port of the electric vehicle nearby and plug it back into the charging gun holder 16 nearby after charging is completed.

[0039] For example, when the charging port of an electric vehicle is on its left side, the user can manually rotate the rocker arm 132 horizontally to the left side of the vehicle before or after the vehicle enters the parking position, so as to plug the charging gun 12 into the charging port on the left side of the electric vehicle. After charging is completed, the charging gun 12 can be plugged back into the charging gun seat 16 at the end of the rocker arm 132.

[0040] For another example, when the charging port of an electric vehicle is on its right side, the user can manually rotate the rocker arm 132 horizontally to the right side of the vehicle before or after the vehicle enters the parking position, so as to plug the electric gun 12 into the charging port on the right side of the electric vehicle, and after charging is completed, plug the charging gun 12 back into the charging gun holder 16 at the end of the rocker arm 132.

[0041] By reducing the distance between the charging gun 12 and the charging port both horizontally and vertically, the required length of the charging cable's movable section 142 is shortened, and this length is limited to less than the aforementioned first height. This further prevents charging failures caused by cable entanglement and the risk of electric shock from the charging gun 12 and charging cable accidentally falling to the ground or onto the vehicle tray 151. Furthermore, by using the swing arm 132 to position and rotate the charging gun holder 16 within the parking space near the charging port, users can complete all vehicle charging operations in situ without having to step over the vehicle tray 151, thus enhancing safety and convenience.

[0042] Furthermore, in some embodiments, the charging gun holder 16 may include a telescopic mechanism (e.g., a spring balancer) and a hook. Here, the telescopic mechanism can be located at the end of the rocker arm 132 and elastically connected to the hook supporting the charging gun 12. It can extend under the user's pulling force, allowing the charging gun to descend and connect to the electric vehicle's charging port. Later, when the user unplugs the charging gun 12 after charging is complete, the telescopic mechanism can rebound after losing the pulling force provided by the user and the charging port, allowing the charging gun 12 to automatically retract to the end of the rocker arm 132. In this way, the present invention can effectively prevent the drooping charging gun 12 from becoming entangled with other cables and the garage frame, and prevent it from colliding with vehicles parked in the current parking space or adjacent parking spaces or the garage frame when the vehicle loading tray 151 is moved left or right. Compared to existing technologies that use a cable reel to retract the charging cable, this telescopic mechanism does not involve winding the charging cable. This effectively prevents the charging cable from becoming entangled, which can affect its normal extension and retraction, and it also prevents frequent and excessive bending of the charging cable, which can affect its service life.

[0043] In addition, in some embodiments, a resistance mechanism may preferably be provided on the rotating shaft 131 to limit the uncontrolled rotation of the rocker arm 132, so as to prevent the rocker arm 132 and the charging gun 12 from colliding with vehicles parked in the current parking space and adjacent parking spaces or the frame of the vertical garage when the vehicle loading tray 151 is moved left or right under the action of wind.

[0044] In addition, in some embodiments, a return mechanism may preferably be provided between the rotating shaft 131 and the rocker arm 132, which is used to drive the rocker arm 132 back to the middle area of ​​the parking position after the charging gun 12 is inserted back into the second end of the rocker arm 132, so as to further avoid collision between it and the charging gun 12 and the vehicles parked in the current parking space and the adjacent parking space or the frame of the vertical parking garage when the vehicle loading tray moves left and right.

[0045] Furthermore, in some embodiments, the above-mentioned charging device provided by the present invention may also be preferably configured with a first controller and a first human-computer interaction interface, and the rotating shaft 131 may be realized by a rotating motor. Specifically, the first human-computer interaction interface may be a rotary button, a touch screen or a QR code bound to a cloud server, which is provided at the entrance and exit of the stereo garage and / or on each vehicle loading tray 151 to obtain the rotation instruction indicating the position of the charging port provided by the user, and transmit the instruction to the first controller in real time. The first controller can be integrated into the charging pile 11, and is used to adjust the rotation direction of the rotating shaft 131 according to the position of the charging port of the electric vehicle, so as to rotate and move the charging gun 12 to the side where the charging port is located, thereby eliminating the trouble of having the user enter the parking position to manually adjust the rotating support mechanism, so as to save charging preparation time and avoid safety hazards caused by people entering the stereo parking garage.

[0046] Those skilled in the art will understand that the above-mentioned semi-automatic control solution based on the human-computer interaction interface in the form of a rotary button, touch screen or QR code is only a non-limiting implementation method provided by the present invention, which is intended to clearly demonstrate the main concept of the present invention and provide a preferred solution for simplifying the control logic and reducing maintenance and repair costs, rather than to limit the scope of protection of the present invention.

[0047] Optionally, in other embodiments, technicians in this field may not use the above-mentioned human-computer interaction interface, but instead use a camera to capture images of vehicles entering the warehouse, and automatically identify the position of the charging port through a vehicle model recognition algorithm or an object recognition algorithm for the charging port, so as to achieve the same technical effect of automatically adjusting the rotation direction of the rotating shaft 131.

[0048] Furthermore, for a charging device used in a stereo garage, the above-mentioned rotating support mechanism can be fixedly connected to the rear side of the vehicle loading tray and, together with the vehicle loading tray, can be raised and lowered and / or moved laterally between multiple parking positions in the stereo garage.

[0049] Please refer to Figures 2 to 4 for details. Figure 2 shows a schematic diagram of the structure of a charging device with a lateral movement function according to some embodiments of the present invention. Figure 3 shows a schematic diagram of the structure of a charging device with a lifting function according to some embodiments of the present invention. Figure 4 shows a schematic diagram of the structure of a charging device with a lateral movement and lifting function according to some embodiments of the present invention.

[0050] In the embodiment shown in FIG. 2 , for a vehicle loading tray 152 having only a transverse movement function, the charging device may further include a first drag chain support and a transverse movement drag chain 181 .

[0051] Specifically, the first drag chain support member can be a transverse limiting groove 171, which extends along the transverse direction of the vehicle tray 152, and at least one side thereof (e.g., the upper side, the lower side, the front side, or the rear side) is provided with a first strip-shaped opening extending along the transverse direction. The bending radius of the transverse drag chain 181 is greater than the maximum bending radius of the charging cable. Its first end is fixed to a first position (e.g., the right side) of the transverse limiting groove 171, and its second end is fixed to a second position (e.g., the middle of the rear side) of the vehicle tray 152. As the vehicle tray 152 moves laterally to the left, it is inserted into the transverse limiting groove 171 through the first strip-shaped opening, or as the vehicle tray 152 moves laterally to the right, it is dragged out of the transverse limiting groove 171 through the first strip-shaped opening.

[0052] The first end of the fixed section 141 of the charging cable is connected to the power supply in the charging pile 11, while the second end thereof extends into the transverse drag chain 181 through the above-mentioned first position, and extends out of the transverse drag chain 181 from the above-mentioned second position, and is then fixedly connected to the rotating shaft 131 of the rotating support mechanism through the vehicle loading tray 152. In this way, the fixed section 141 of the charging cable can be inserted into the transverse limiting groove 171 or pulled out of the transverse limiting groove 171 as the vehicle loading tray 152 moves laterally under the restriction of the transverse drag chain 181, thereby maintaining the charging of the electric vehicle during the transverse movement of the vehicle loading tray 152, avoiding entanglement with the charging cables of other charging spaces and / or equipment such as the vertical garage frame, which may cause cable damage or garage alarm, and avoiding damage or breakage due to excessive bending.

[0053] In addition, in the embodiment shown in FIG. 3 , for the vehicle loading tray 153 having only a lifting function, the charging device may further include a second drag chain support and a lifting drag chain 182 .

[0054] Specifically, the second drag chain support member can be a longitudinal limit groove 172, which extends along the lifting direction of the vehicle tray 153, and at least one side thereof (e.g., the front, rear, left, or right side) is provided with a second strip-shaped opening extending along the lifting direction. The bending radius of the lifting drag chain 182 is greater than the maximum bending radius of the charging cable. Its first end is fixed to a first position (e.g., the upper side) of the longitudinal limit groove 172, and its second end is fixed to a second position (e.g., the middle of the rear side) of the vehicle tray 153. As the vehicle tray 153 moves downward longitudinally, it is inserted into the longitudinal limit groove 172 through the second strip-shaped opening, or as the vehicle tray 153 moves upward longitudinally, it is pulled out of the longitudinal limit groove 172 through the second strip-shaped opening.

[0055] The first end of the fixed section 141 of the charging cable is connected to the power supply in the charging pile 11, while the second end thereof extends into the lifting and dragging chain 182 through the first position, and extends out of the lifting and dragging chain 182 from the second position, and is then fixedly connected to the rotating shaft 131 of the rotating support mechanism through the vehicle loading tray 153. In this way, the fixed section 141 of the charging cable can be inserted into the longitudinal limit groove 172 or pulled out of the longitudinal limit groove 172 as the vehicle loading tray 153 moves longitudinally, under the restriction of the lifting and dragging chain 182, thereby maintaining the charging of the electric vehicle during the longitudinal movement of the vehicle loading tray 153, avoiding entanglement with the charging cables of other charging spaces and / or equipment such as the vertical garage frame, which may cause cable damage or garage alarm, and avoiding damage or breakage due to excessive bending.

[0056] Those skilled in the art will understand that the above-mentioned longitudinal limit groove 172 is only a non-limiting embodiment provided by the present invention, which is intended to clearly demonstrate the main concept of the present invention and provide a specific solution that is easy for the public to implement, rather than to limit the scope of protection of the present invention.

[0057] Optionally, in other embodiments, for the vehicle loading tray 153 that only has the lifting function, the above-mentioned charging device may also only include a lifting drag chain 182, without including the longitudinal limit groove 172. At this time, the first end of the lifting drag chain 182 can be fixed to the sixth position of the stereo garage frame, and remain vertically drooping under the action of gravity and the constraint of the drag chain joint. Afterwards, the lifting drag chain 182 can be unfolded downward as the vehicle loading tray 153 descends, or bend upward as the vehicle loading tray 153 rises, so that it will not be entangled with the charging cables of other charging parking spaces and / or equipment such as the stereo garage frame, causing cable damage or garage alarms, and can also prevent the charging cable from being damaged or broken due to excessive bending.

[0058] In addition, in the embodiment shown in FIG. 4 , for a vehicle loading pallet having both transverse movement and lifting functions, the charging device may further include a third drag chain support, a transverse movement drag chain 183 and a lifting drag chain 184 .

[0059] Specifically, the third drag chain support member can be a transverse limiting groove 173. The vehicle loading pallet can include a pallet body 1541 and a pallet frame 1542. The pallet frame 1542 only has a transverse movement function. The pallet body 1541 has both lifting and transverse movement functions. It can be lowered to the lower parking position to allow vehicles to enter and exit the parking garage, and then raised back to the upper parking position to be inserted into the pallet frame 1542, and then transversely move with the pallet frame 1542.

[0060] The transverse limiting groove 173 extends along the lateral movement direction of the vehicle loading tray, and a first strip-shaped opening extending along the lateral movement direction is provided on at least one side (e.g., the upper side, lower side, front side, or rear side) of the transverse limiting groove 173. The transverse drag chain 183 has a bending radius greater than the maximum bending radius of the charging cable. Its first end is fixed to a first position (e.g., the right side) of the transverse limiting groove 173, and its second end is fixed to a second position (e.g., the middle of the rear side) of the tray frame 1542. As the tray frame 1542 moves laterally to the left, it is inserted into the transverse limiting groove 173 through the first strip-shaped opening, and as the tray frame 1542 moves laterally to the right, it is pulled out of the transverse limiting groove 173 through the first strip-shaped opening. The bending radius of the lifting drag chain 184 is also greater than the maximum bending radius of the charging cable. Its first end is also fixed to the second position of the tray frame 1542 (for example: the middle of the rear side), and its second end is fixed to the third position of the tray body 1541 (for example: the middle of the rear side), and unfolds as the tray body 1541 moves downward longitudinally, or bends as the tray body 1541 moves upward longitudinally.

[0061] The fixed section 141 of the charging cable can be divided into two sections. Here, the two sections of the charging cable can be composed of two independent charging cables, or a complete charging cable defined as two sections. The first end of the first fixed section is connected to the power supply located at the charging pile 11, and the second end thereof extends into the transverse drag chain 183 via the above-mentioned first position and extends out of the transverse drag chain 183 from the above-mentioned second position. The first end of the second fixed section is conductively connected to the second end of the first fixed section, and the second end thereof extends into the lifting drag chain 184 from the above-mentioned second position and extends out of the lifting drag chain 184 from the above-mentioned third position, and is then fixedly connected to the rotating shaft 131 of the rotating support mechanism via the tray body 1541.

[0062] In this way, the first fixed section of the charging cable can be inserted into the lateral limit groove 173 or pulled out of the lateral limit groove 173 as the pallet frame 1542 moves laterally, under the restriction of the transverse drag chain 183, thereby maintaining the charging of the electric vehicle during the lateral movement of the vehicle-carrying pallet, avoiding entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical storage frame, which may cause cable damage or garage alarms, and avoid damage or breakage due to excessive bending. The second fixed section of the charging cable can be downwardly extended or upwardly bent as the pallet 1541 moves longitudinally, under the restriction of the lifting drag chain 184, thereby maintaining the charging of the electric vehicle during the longitudinal movement of the vehicle-carrying pallet, avoiding entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical storage frame, which may cause cable damage or garage alarms, and avoid damage or breakage due to excessive bending.

[0063] Those skilled in the art will understand that the transverse limit grooves 171 and 173 shown in Figures 2 and 4 are only a non-restrictive embodiment provided by the present invention, which is intended to clearly demonstrate the main concept of the present invention and provide a preferred solution that can accurately constrain the lateral position of the transverse drag chains 181 and 183, rather than to limit the scope of protection of the present invention.

[0064] Optionally, in other embodiments, the first drag chain support and the third drag chain support may also be the ground behind the bottom parking space, or supporting components such as garage beams behind the upper parking space, so as to achieve the same effect of avoiding the entanglement of the charging cable of this parking space with the charging cables of other charging spaces and / or equipment such as the vertical garage frame, which may cause cable damage or garage alarm, and avoiding the damage or breakage of the charging cable due to excessive bending.

[0065] Those skilled in the art will also understand that the charging devices shown in Figures 1 to 4 are only some non-limiting implementation methods provided by the present invention, which are intended to clearly demonstrate the main concepts of the present invention and provide some specific solutions that are convenient for the public to implement, rather than to limit the scope of protection of the present invention.

[0067] In the embodiment shown in Figure 5, the above-mentioned rotating support mechanism may include a rotating shaft 231, a rocker arm 232, a vertical pole 233, and a charging gun holder 26. Specifically, the rotating shaft 231 can be vertically mounted on the rear edge of the vehicle loading tray 25 in the parking position. The rocker arm 232 can rotate horizontally under the drive of the rotating shaft 231 to rotate and move the charging gun 22 it carries to the side where the charging port of the electric vehicle is located. The first end of the vertical pole 233 is connected to the second end of the rocker arm 232, and its second end extends upward to a first height (for example, the height of the charging port) and is provided with a charging gun holder 26 for carrying an idle charging gun 22. The length of the movable section 242 of the charging cable is less than the first height. It extends beyond the second end of the vertical pole 233, allowing the user to plug the charging gun 22 at its end into the charging port of the electric vehicle nearby and plug it back into the charging gun holder 26 nearby after charging is completed.

[0068] For example, when the charging port of the electric vehicle is on its left side, the user can rotate the rocker arm 232 horizontally to the left side of the vehicle before the vehicle enters the parking position, so as to plug the charging gun 22 into the charging port on the left side of the electric vehicle. After charging is completed, the charging gun 22 can be plugged back into the charging gun seat 26 at the end of the pole 233.

[0069] For another example, when the charging port of an electric vehicle is on its right side, the user can rotate the rocker arm 232 horizontally to the right side of the vehicle before the vehicle enters the parking position, so as to plug the electric gun 22 into the charging port on the right side of the electric vehicle, and after charging is completed, plug the charging gun 22 back into the charging gun seat 26 at the end of the pole 233.

[0070] By reducing the distance between the charging gun 22 and the charging port both horizontally and vertically, the required length of the active charging cable segment 242 is shortened, and this length is limited to less than the aforementioned first height. This further prevents charging failures caused by cable entanglement and the risk of electric shock from the charging gun 22 and charging cable accidentally falling to the ground or onto the vehicle tray 25. Furthermore, by using a swing arm 232 to position and rotate the charging gun holder 26 within the parking space near the charging port, users can complete all vehicle charging operations in situ without having to step over the vehicle tray 25, thus enhancing safety and convenience.

[0071] Furthermore, as shown in FIG5 , the charging gun holder 26 can be positioned toward the outside of the vehicle loading tray 25 so that the direction in which the charging gun 22 is inserted into the charging gun socket 26 is consistent with the direction in which the charging gun 22 is inserted into the vehicle charging port, allowing the user to observe the position of the charging gun 22 and facilitating quick positioning and use of the charging gun 22. Furthermore, the charging gun holder 26 can be configured as an elastic hook with a telescopic function, configured to extend under the action of a user's pulling force to allow the charging gun 22 to be plugged into the charging port of the electric vehicle, and to rebound after the pulling force provided by the user and the charging port is lost, so that the charging gun 22 is automatically retracted to the end of the rotating support mechanism, thereby preventing the drooping charging gun from becoming entangled with other cables or the garage frame, and preventing it from colliding with vehicles parked in the current parking space and adjacent parking spaces or the garage frame when the vehicle loading tray is moved left or right.

[0072] In addition, in some embodiments, an insulating connector 291 may be provided between the rotating shaft 231 and the vehicle loading tray 25 for insulating and isolating the charging pile 21 and the vehicle loading tray 25 to eliminate the hidden danger of leakage of the power supply to the vehicle loading tray 25.

[0073] In addition, in some embodiments, a parking space ground lock 292 may be provided in the middle position of the vehicle loading tray 25. The control line of the parking space ground lock 292 may be connected to the first controller in the charging pile 21 via the transverse drag chain 28 and / or the lifting drag chain to avoid electrical or control failures caused by entanglement with other cables. Accordingly, after the user enables the charging function, the first controller may send an unlocking command to the parking space ground lock 292 via the control line to allow the user to drive the vehicle into the vehicle loading tray 25, and after the vehicle leaves the vehicle loading tray 25, the first controller may send a locking command to the parking space ground lock 292 via the control line to prohibit the user from driving the vehicle into the vehicle loading tray 25 without authorization, thereby realizing wired control of the parking space ground lock 292 of the lifting and transverse pallet.

[0074] In addition, in some embodiments, the rear side of the vehicle loading tray 25 may be provided with an anti-return beam 293 to prevent the vehicle from colliding with the charging device during the process of backing into the garage. Furthermore, the sixth height of the anti-return beam 293 may be less than the fifth height of the vehicle chassis and less than the installation height of the rocker arm 232 to avoid interference with the vehicle chassis and the rotating rocker arm 232, and to ensure that the rocker arm 232 rotating toward the vehicle loading tray 25 can smoothly move the charging gun 22 to the charging port position of the electric vehicle, thereby eliminating the need to further reserve space for the rocker arm 232 to rotate behind the vehicle loading tray 25, thereby achieving a compact design of the parking position.

[0075] Furthermore, in the embodiment shown in Figure 6, the aforementioned rotating support mechanism may include a rotating shaft 331, a rocker arm 332, a vertical rod 333, a crossbar 334, and a charging gun holder 36. Specifically, the vertical rod 333 can be mounted vertically on the rear edge of the vehicle loading tray 35 in the parking position. The rotating shaft 331 is mounted horizontally at a first height of the vertical rod 333. Driven by the rotating shaft 331, the rocker arm 332 can rotate vertically to rotate and move the charging gun 32 it carries to the side of the electric vehicle's charging port. The first end of the crossbar 334 is connected to the second end of the rocker arm 332, while its second end extends forward to the electric vehicle's charging port and is provided with a charging gun holder 36 for holding an unused charging gun 32. The active section 342 of the charging cable is shorter than the first height and extends beyond the second end of the crossbar 334, allowing the user to plug the charging gun 32 at its end into the nearest charging port of the electric vehicle and then plug it back into the charging gun holder 36 after charging is complete.

[0076] For example, when the charging port of the electric vehicle is on its left side, the user can rotate the rocker arm 332 vertically to the left side of the vehicle before or after the vehicle enters the parking position to plug the charging gun 32 into the charging port on the left side of the electric vehicle. After charging is completed, the charging gun 32 can be plugged back into the charging gun seat 36 at the end of the cross bar 334.

[0077] For another example, when the charging port of an electric vehicle is on its right side, the user can vertically rotate the rocker arm 332 to the right side of the vehicle before or after the vehicle enters the parking position to plug the electric gun 32 into the charging port on the right side of the electric vehicle. After charging is completed, the charging gun 32 can be plugged back into the charging gun seat 36 at the end of the cross bar 334.

[0078] By reducing the distance between the charging gun 32 and the charging port in six directions—front, back, left, right, up, and down—the required length of the charging cable's movable segment 342 is reduced, and this length is limited to less than the aforementioned first height. This further prevents charging failures caused by cable entanglement and the risk of electric shock from the charging gun 32 and charging cable accidentally falling to the ground or onto the vehicle tray 35. Furthermore, by using a swing arm 332 to position and rotate the charging gun holder 36 within the parking space near the charging port, users can complete all vehicle charging operations in situ without having to step over the vehicle tray 35, thus enhancing safety and convenience.

[0079] Furthermore, as shown in FIG6 , the charging gun holder 36 can be positioned toward the outside of the vehicle loading tray 35 so that the direction in which the charging gun 32 is inserted into the charging gun socket 36 is consistent with the direction in which it is inserted into the vehicle charging port, allowing the user to observe the position of the charging gun 32 and facilitating quick positioning and use of the charging gun 32. Furthermore, the charging gun holder 36 can be configured as an elastic hook with a telescopic function, configured to extend under the action of a user's pulling force to allow the charging gun 32 to be plugged into the charging port of the electric vehicle, and to rebound upon loss of the pulling force provided by the user and the charging port, so that the charging gun 32 is automatically retracted to the end of the rotating support mechanism, thereby preventing the drooping charging gun from becoming entangled with other cables or the garage frame, and preventing it from colliding with vehicles parked in the current parking space and adjacent parking spaces or the garage frame when the vehicle loading tray is moved left or right.

[0080] In addition, in some embodiments, an insulating connector 391 may be provided between the vertical pole 333 and the vehicle loading tray 35 to provide insulation isolation between the charging pile 31 and the vehicle loading tray 35 to eliminate the hidden danger of leakage of the power supply to the vehicle loading tray 35.

[0081] In addition, in some embodiments, a parking ground lock may be provided in the middle of the vehicle loading tray 35. The control line of the parking ground lock may be connected to the first controller in the charging pile 31 via the transverse drag chain 38 and / or the lifting drag chain to avoid electrical or control failures caused by entanglement with other cables. Accordingly, after the user activates the charging function, the first controller may send an unlocking command to the parking ground lock via the control line to allow the user to drive the vehicle into the vehicle loading tray 35, and after the vehicle leaves the vehicle loading tray 35, the first controller may send a locking command to the parking ground lock via the control line to prohibit the user from driving the vehicle into the vehicle loading tray 35 without authorization, thereby realizing wired control of the parking ground lock of the lifting and transverse pallet.

[0082] In some embodiments, a backstop beam 393 may be provided on the rear side of the vehicle loading tray 35 to prevent the vehicle from colliding with the charging device when backing into the vehicle. Furthermore, the sixth height of the backstop beam 393 may be less than the fifth height of the vehicle chassis to prevent interference with the vehicle chassis.

[0083] Furthermore, in the embodiment shown in FIG7 , the aforementioned rotating support mechanism may include a rotating shaft 431 and a rocker arm 432, with charging gun holders 461 and 462 respectively positioned on either side of the rear of the parking space. Specifically, the rotating shaft 431 may be vertically mounted on the rear edge of the vehicle loading tray 451 in the parking space, with its fourth height being less than the fifth height of the electric vehicle chassis to ensure that the rocker arm 432, rotating toward the vehicle loading tray 451, does not collide with an electric vehicle parked in the parking space. Driven by the rotating shaft 431, the rocker arm 432 may rotate horizontally at the fourth height to horizontally rotate and move the charging gun it carries to the side of the electric vehicle's charging port. The movable section 442 of the charging cable extends beyond the second end of the rocker arm 432 at the fourth height, allowing the user to plug the charging gun at its end into the nearest charging port of the electric vehicle and, after charging is complete, plug it back into the nearest charging gun holder 461 or 462 on the corresponding side.

[0084] For example, when the charging port of an electric vehicle is on its left side, the user can rotate the rocker arm 432 horizontally to the left side of the vehicle before the vehicle enters the parking position, so as to plug the charging gun into the charging port on the left side of the electric vehicle, and after charging is completed, plug the charging gun back into the charging gun holder 461 on the left side of the parking position.

[0085] For another example, when the charging port of an electric vehicle is on its right side, the user can rotate the rocker arm 432 horizontally to the right side of the vehicle before the vehicle enters the parking position, so as to plug the electric gun into the charging port on the right side of the electric vehicle, and after charging is completed, plug the charging gun back into the charging gun holder 462 on the right side of the parking position.

[0086] By reducing the distance between the charging gun and the charging port in a planar direction, and thereby shortening the required length of the charging cable's movable segment 442, the present invention effectively prevents charging failures caused by cable entanglement. Furthermore, by using a swing arm 432 to rotate and move an idle charging gun to a position within the parking space near the charging port, users can complete all vehicle charging operations in situ without having to step over the vehicle loading tray 451, thus providing greater safety and convenience.

[0087] Furthermore, in some embodiments, for the embodiments rotating toward the vehicle loading pallet 451, a limiting mechanism 494 may preferably be provided on the left side, right side and / or rear side of the vehicle loading pallet 451 to limit the rotation range of the rocker arm 432 on the left side, right side and / or rear side of the vehicle loading pallet 451, so as to avoid the rocker arm 432 exceeding the vehicle loading pallet 451 and colliding with a vehicle parked in an adjacent parking space or a vertical storage frame.

[0088] In addition, in some embodiments, the charging gun holders 461 and 462 can be set upward or forward to facilitate the user to insert the charging gun and prevent the charging gun and the active section 442 of the charging cable connected to its end from exceeding the range of the vehicle loading pallet 451 and becoming entangled with the charging cable or the vertical storage frame of the adjacent parking space.

[0089] In addition, in some embodiments, the rear side of the vehicle loading tray 451 may be provided with an anti-return beam 493 to prevent the vehicle from colliding with the charging device during the process of backing into the garage. Furthermore, the fourth height of the rotation plane of the rocker arm 432 may be greater than the sixth height of the anti-return beam 493 and less than the fifth height of the vehicle chassis, so as to ensure that the rocker arm 432 rotating toward the vehicle loading tray 451 can smoothly move the charging gun to the charging port position of the electric vehicle and avoid interference with the vehicle chassis, thereby eliminating the need to reserve further rotation space for the rocker arm 432 behind the vehicle loading tray 451, thereby realizing a compact design of the parking space.

[0090] Furthermore, for a charging device used in a stereo garage, the above-mentioned rotating support mechanism can be fixedly connected to the rear side of the vehicle loading tray and, together with the vehicle loading tray, can be raised and lowered and / or moved laterally between multiple parking positions in the stereo garage.

[0091] As shown in FIG. 7 , for a vehicle loading tray 451 having only a transverse movement function, the charging device may further include a fourth drag chain support and a transverse movement drag chain 481 .

[0092] Specifically, the fourth drag chain support member can be a transverse limiting groove 471, which extends along the transverse direction of the vehicle tray 451, and at least one side thereof (e.g., the upper side, the lower side, the front side, or the rear side) is provided with a first strip-shaped opening extending along the transverse direction. The bending radius of the transverse drag chain 481 is greater than the maximum bending radius of the charging cable. Its first end is fixed to a first position (e.g., the right side) of the transverse limiting groove 471, and its second end is fixed to a second position (e.g., the middle of the rear side) of the vehicle tray 451. As the vehicle tray 451 moves laterally to the left, it is inserted into the transverse limiting groove 471 through the first strip-shaped opening, or as the vehicle tray 451 moves laterally to the right, it is dragged out of the transverse limiting groove 471 through the first strip-shaped opening.

[0093] The first end of the fixed section 441 of the charging cable is connected to the power supply in the charging pile 41, while the second end thereof extends into the transverse drag chain 481 through the above-mentioned first position, and extends out of the transverse drag chain 481 from the above-mentioned second position, and is then fixedly connected to the rotating shaft 431 of the rotating support mechanism through the vehicle loading tray 451. In this way, the fixed section 441 of the charging cable can be inserted into the transverse limiting groove 471 or pulled out of the transverse limiting groove 471 as the vehicle loading tray 451 moves laterally under the restriction of the transverse drag chain 481, thereby maintaining the charging of the electric vehicle during the transverse movement of the vehicle loading tray 451, avoiding entanglement with the charging cables of other charging spaces and / or equipment such as the vertical garage frame, which may cause cable damage or garage alarm, and avoiding damage or breakage due to excessive bending.

[0094] In addition, please refer to Figures 8, 9, and 10A-10B. Figure 8 shows a schematic diagram of the structure of a charging device with a lifting function according to some embodiments of the present invention. Figure 9 shows a schematic diagram of the structure of a charging device with a lateral movement and lifting function according to some embodiments of the present invention. Figures 10A-10B show schematic diagrams of the structure of a charging device with a lateral movement and lifting function according to some embodiments of the present invention.

[0095] In the embodiment shown in FIG. 8 , for a vehicle loading tray 452 having only a lifting function, the charging device may further include a fifth drag chain support and a lifting drag chain 482 .

[0096] Specifically, the fifth drag chain support member can be a longitudinal limit groove 472, which extends along the lifting direction of the vehicle tray 452, and has a second strip-shaped opening extending along the lifting direction on at least one side (e.g., the front, rear, left, or right side). The lifting drag chain 482 has a bending radius greater than the maximum bending radius of the charging cable. Its first end is fixed to a first position (e.g., the upper side) of the longitudinal limit groove 472, and its second end is fixed to a second position (e.g., the middle of the rear side) of the vehicle tray 452. As the vehicle tray 452 moves downward longitudinally, it is inserted into the longitudinal limit groove 472 through the second strip-shaped opening, or as the vehicle tray 452 moves upward longitudinally, it is pulled out of the longitudinal limit groove 472 through the second strip-shaped opening.

[0097] The first end of the fixed section 441 of the charging cable is connected to the power supply in the charging pile 41, while the second end thereof extends into the lifting drag chain 482 through the first position, extends out of the lifting drag chain 482 from the second position, and is then fixedly connected to the rotating shaft 431 of the rotating support mechanism through the vehicle loading tray 452. In this way, the fixed section 441 of the charging cable can be inserted into the longitudinal limit groove 472 or pulled out of the longitudinal limit groove 472 as the vehicle loading tray 452 moves longitudinally under the restriction of the lifting drag chain 482, thereby maintaining the charging of the electric vehicle during the longitudinal movement of the vehicle loading tray 452, avoiding entanglement with charging cables of other charging spaces and / or equipment such as the vertical garage frame, which may cause cable damage or garage alarm, and avoiding damage or breakage due to excessive bending.

[0098] In addition, in other embodiments, for a vehicle loading tray 452 that only has a lifting function, the above-mentioned charging device may also only include a lifting drag chain 482 without including the longitudinal limit groove 472. In this case, the first end of the lifting drag chain 482 can be fixed to the sixth position of the stereo garage frame and remain vertically drooping under the action of gravity and the constraint of the drag chain joint. Afterwards, the lifting drag chain 482 can be deployed downward as the vehicle loading tray 452 descends, or bend upward as the vehicle loading tray 452 rises, so that it will not be entangled with the charging cables of other charging parking spaces and / or equipment such as the stereo garage frame, causing cable damage or garage alarms, and it can also prevent the charging cable from being damaged or broken due to excessive bending.

[0099] In addition, in the embodiment shown in FIG. 9 , for a vehicle loading pallet having both transverse movement and lifting functions, the charging device may further include a sixth drag chain support, a transverse movement drag chain 483 and a lifting drag chain 484 .

[0100] Specifically, the sixth drag chain support member may be a transverse limiting groove 473. The vehicle loading pallet may include a pallet body 4541 and a pallet frame 4542. The pallet frame 4542 only has a transverse movement function. The pallet body 4541 has both lifting and transverse movement functions. It can be lowered to the lower parking position to allow vehicles to enter and exit the parking garage, and then raised back to the upper parking position to fit into the pallet frame 4542, and then transversely move with the pallet frame 4542.

[0101] The transverse limiting groove 473 extends along the lateral movement direction of the vehicle loading tray, and a first strip-shaped opening extending along the lateral movement direction is provided on at least one side (e.g., the upper side, lower side, front side, or rear side) of the transverse limiting groove 473. The transverse drag chain 483 has a bending radius greater than the maximum bending radius of the charging cable. Its first end is fixed to a first position (e.g., the right side) of the transverse limiting groove 473, and its second end is fixed to a second position (e.g., the middle of the rear side) of the tray frame 4542. As the tray frame 4542 moves laterally to the left, it is inserted into the transverse limiting groove 473 through the first strip-shaped opening, and as the tray frame 4542 moves laterally to the right, it is pulled out of the transverse limiting groove 473 through the first strip-shaped opening. The bending radius of the lifting drag chain 484 is also greater than the maximum bending radius of the charging cable. Its first end is also fixed to the second position of the tray frame 4542 (for example: the middle of the rear side), and its second end is fixed to the third position of the tray body 4541 (for example: the middle of the rear side), and unfolds as the tray body 4541 moves downward longitudinally, or bends as the tray body 4541 moves upward longitudinally.

[0102] The fixed section of the charging cable can be divided into two sections (i.e., a first fixed section and a second fixed section). Here, the two-section charging cable can be composed of two independent charging cables, or it can be a complete charging cable defined as two sections. The first end of the first fixed section is connected to the power supply located at the charging pile 41, and the second end thereof extends into the transverse drag chain 483 via the above-mentioned first position, and extends the transverse drag chain 483 from the above-mentioned second position. The first end of the second fixed section is conductively connected to the second end of the first fixed section, and the second end thereof extends into the lifting drag chain 484 from the above-mentioned second position, and extends the lifting drag chain 484 from the above-mentioned third position, and is then fixedly connected to the rotating shaft 431 of the rotating support mechanism via the tray body 4541.

[0103] In this way, the first fixed section of the charging cable can be inserted into the transverse limiting groove 473 or pulled out of the transverse limiting groove 473 as the pallet frame 4542 moves laterally, under the restriction of the transverse drag chain 483, thereby maintaining the charging of the electric vehicle during the transverse movement of the vehicle loading pallet, avoiding entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical storage frame, which may cause cable damage or garage alarms, and avoid damage or breakage due to excessive bending. The second fixed section of the charging cable can be unfolded or appropriately bent as the pallet 4541 moves longitudinally, under the restriction of the lifting drag chain 484, thereby maintaining the charging of the electric vehicle during the longitudinal movement of the vehicle loading pallet, avoiding entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical storage frame, which may cause cable damage or garage alarms, and avoid damage or breakage due to excessive bending.

[0104] In addition, in the embodiment shown in FIG. 10A to FIG. 10B , for the vehicle loading pallet having both lateral movement and lifting functions, the lifting drag chain 484 in the above embodiment can also be replaced by a connecting mechanism.

[0105] Specifically, the charging device only needs to be equipped with a seventh drag chain support and a transverse drag chain 483. The seventh drag chain support can be a transverse limit groove 473. The tray frame 4542 in the vehicle loading tray only has a transverse movement function, and its fifth position is provided with a second conductive member 102. The tray body 4541 has both lifting and transverse movement functions, and its fourth position is provided with a first conductive member 101, which can be lowered to the lower parking position to allow vehicles to enter and exit the warehouse, and rise back to the upper parking position, embedded in the tray frame 4542, to achieve conduction between the first conductive member 101 and the second conductive member 102, and then move transversely with the tray frame 4542.

[0106] Correspondingly, the first end of the transverse drag chain 483 is fixed to the first position (e.g., the right side) of the transverse limit groove 473, and the second end is fixed to the second position (e.g., the middle of the rear side) of the tray frame 4542, and moves laterally to the left with the tray frame 4542. The fixed section of the charging cable can be composed of at least two independent charging cables and divided into two sections (i.e., a third fixed section and a fourth fixed section). Here, the first end of the third fixed section is connected to the power supply 41, while the second end thereof extends into the transverse drag chain 483 through the first position and extends out of the transverse drag chain 483 from the second position to be fixedly connected to the first conductive member 101 thereof via the tray frame 4542. The first end of the fourth fixed section is fixedly connected to the second conductive member 102, and the second end thereof is fixedly connected to the rotating shaft 431 of the rotating support mechanism via a cable channel provided in the tray body 4541.

[0107] Furthermore, in some embodiments, the first conductive member 101 may include a first support structure, a first elastic buffer structure, and a first conductor. Here, the first support structure is positioned at a fourth position on the tray body 4541 to support the first elastic buffer structure. The first end of the first elastic buffer structure is connected to the first support structure, while the second end is connected to the first conductor. This structure is used to fine-tune the relative position of the first conductor to improve the success rate of its docking with the second conductive member 102. The structure also deforms when the tray body 4541 is inserted into the tray frame 4542 to reduce contact resistance between the first conductor and the second conductive member 102.

[0108] Furthermore, in some embodiments, the second conductive member 102 may include a second support structure, a second elastic buffer structure, and a second conductive body. Here, the second support structure is positioned at a fifth position on the tray frame 4542 to support the second elastic buffer structure. The first end of the second elastic buffer structure is connected to the second support structure, while the second end is connected to the second conductive body. This structure is used to fine-tune the relative position of the second conductive body to improve the success rate of its docking with the first conductive member 101. The second elastic buffer structure also deforms when the tray body 4541 is inserted into the tray frame 4542, thereby reducing the contact resistance between the second conductive body and the first conductive member 101.

[0109] Compared to the embodiment shown in FIG9 , the docking mechanism used in the embodiment shown in FIG10A and FIG10B can effectively prevent the drooping lifting and lowering drag chain 484 from interfering with the parking space on the lower level, and is therefore more suitable for use in three-story parking garages with three or more floors. In addition, because the third fixed section of the charging cable can still be inserted into or pulled out of the transverse limiting groove 473 as the pallet frame 4542 moves laterally under the restriction of the transverse drag chain 483, this solution can still maintain charging of the electric vehicle during the lateral movement of the vehicle loading pallet, avoiding entanglement with the charging cables of other charging spaces and / or equipment such as the vertical garage frame, which may cause cable damage or garage alarms, and avoid damage or breakage due to excessive bending.

[0110] Those skilled in the art will understand that although the foregoing text only illustrates and describes the relevant embodiments of the drag chain support, transverse drag chains 481, 483, lifting drag chain 482, vehicle loading pallet body 4541, vehicle loading pallet frame 4542, and conductive members 101, 102 based on the rotating support mechanism shown in Figure 7, this is only a non-restrictive description method intended to clearly demonstrate the main concept of the present invention, and is not used to limit the scope of protection of the present invention.

[0111] Optionally, in other embodiments, when the rotating support mechanism shown in Figures 5 and 6 is applied to the transverse moving vehicle loading pallet, lifting vehicle loading pallet and / or transverse moving lifting vehicle loading pallet of the multi-story parking garage, it may also have corresponding structures of drag chain support, transverse moving drag chain, lifting drag chain, vehicle loading pallet body, vehicle loading pallet frame and / or conductive parts to achieve the same technical effect, which will not be repeated here.

[0112] Furthermore, according to a second aspect of the present invention, a multi-story parking garage is provided, comprising M*N parking spaces, M*Ni vehicle loading trays, and at least one electric vehicle charging device as described above in the first aspect of the present invention. Here, M is the number of parking spaces on each floor, N is the number of floors, and i is a natural number not less than 1. Each vehicle loading tray supports lifting and / or lateral movement between multiple parking spaces.

[0113] Further, please refer to Figure 11 and Figures 12A and 12B. Figure 11 shows a schematic structural diagram of a stereo garage provided according to some embodiments of the present invention. Figures 12A and 12B show schematic structural diagrams of the first floor of a stereo garage provided according to some embodiments of the present invention.

[0114] In the embodiment shown in Figures 11 and 12A to 12B, this article discloses a double-layer five-parking space three-dimensional charging garage, wherein the first layer has three parking spaces and is equipped with two transverse vehicle loading pallets 111 with only transverse movement function, and the second layer also has three parking spaces and is equipped with three lifting vehicle loading pallets 112 with only lifting function.

[0115] Specifically, in some embodiments, at least one of the two transverse vehicle loading trays 111 on the first layer can be configured as a charging tray, and each can be equipped with a charging device. Here, the charging device can be adapted to the specific structure of the rotating support mechanism and can adopt the scheme shown in Figures 2, 5, 6, or 7.

[0116] Thus, when a first user needs to park their first vehicle on any of the transverse charging trays 111 on the first floor for charging, they can manipulate the rotating support mechanism before parking to rotate the charging gun to the side where the charging port of the first vehicle is located. Afterwards, the first user can park the first vehicle on the transverse charging tray 111 and insert the charging gun into the charging port of the first vehicle, completing the parking and charging process.

[0117] Afterwards, when the second user needs to pick up the second vehicle from the second-floor parking space above, the multi-story parking garage can first adjust the position of each transverse charging tray 111 below via the transverse motor to free up the parking space below, and then use the lifting motor to lower the lifting vehicle tray 112 where the second vehicle is parked to the first floor, so that the second user can enter the lifting vehicle tray 112 and drive away the second vehicle parked.

[0118] It should be noted that, due to the use of the charging device shown in Figures 2, 5, 6, or 7, the first vehicle can remain charged during lateral movement, and the corresponding charging cable can also maintain a reasonable and controllable motion trajectory within the constraints of the lateral drag chain. Therefore, a stereo garage equipped with the above-mentioned charging device not only has higher charging efficiency, but also effectively overcomes the problem of cable entanglement and breakage caused by excessive bending, thereby improving the charging safety and service life of the stereo garage.

[0119] In addition, in some embodiments, at least one of the three vehicle loading trays 112 on the second layer can be configured as a charging tray and each of them can be equipped with a charging device. Here, the charging device can be adapted to the specific structure of the rotating support mechanism and can be selected from the scheme shown in Figure 3 or Figure 8.

[0120] In this way, when the second user needs to park their second vehicle on any free lift charging tray 112 on the second-floor parking space for charging, the three-dimensional parking garage can first adjust the position of each lower transverse vehicle loading tray 111 laterally via the transverse motor to free up the parking space below, and then lower the lift charging tray 112 selected by the second user to the first floor via the lifting motor to allow the second user to enter the lift charging tray 112, and rotate the charging gun to the side where the charging port of the second vehicle is located by manipulating the above-mentioned rotating support mechanism. Afterwards, the second user can park the second vehicle on the lift charging tray 112 and insert the charging gun into the charging port of the second vehicle to complete the parking and charging operation process.

[0121] Afterwards, when the third user needs to park his third vehicle on any vacant lifting vehicle loading tray 112 on the second-floor parking space, or retrieve the third vehicle from the upper second-floor parking space, the multi-story parking garage can first use the lifting motor to raise the lifting charging tray 112 where the second vehicle is parked to the second-floor parking position, and then use the transverse motor to laterally adjust the position of each transverse vehicle loading tray 111 below to free up the parking space below, and then use the lifting motor to lower the lifting vehicle loading tray 112 where the third vehicle needs to be parked or retrieved to the first floor for the third user to enter the lifting vehicle loading tray 112.

[0122] It should be noted that, due to the use of the charging device shown in Figures 3 or 8, the second vehicle can remain charged during the lifting process, and the corresponding charging cable can also maintain a reasonable and controllable motion trajectory within the constraints of the lifting drag chain. Therefore, a three-dimensional parking garage equipped with the above-mentioned charging device not only has higher charging efficiency, but also effectively overcomes the problem of cable entanglement and breakage caused by excessive bending, thereby improving the charging safety and service life of the three-dimensional parking garage.

[0123] Those skilled in the art will understand that the double-deck, five-bay stereoscopic charging garage shown in Figures 11 and 12A to 12B are only some non-limiting implementation methods provided by the present invention, which are intended to clearly demonstrate the main concepts of the present invention and provide some specific solutions that are convenient for the public to implement, rather than to limit the scope of protection of the present invention.

[0124] Optionally, in other three-story multi-story parking garages, the M-1 car pallets on the first-story parking spaces only need to have a transverse movement function, the M car pallets on the third-story parking spaces only need to have a lifting function, and the M-1 car pallets on the second-story parking spaces need to have both transverse movement and lifting functions to meet the needs of lifting themselves and avoiding the pick-up and placement of cars by the upper-story car pallets.

[0125] Correspondingly, when at least one of the M-1 transverse vehicle loading trays on the first floor of the three-story parking garage is a charging tray, each transverse charging tray can be respectively configured with a charging device as shown in Figure 2, Figure 5, Figure 6 or Figure 7. When at least one of the M lifting vehicle loading trays on the third floor of the three-story parking garage is a charging tray, each lifting charging tray can be respectively configured with a charging device as shown in Figure 3 or Figure 8. When at least one of the M-1 lifting and transverse vehicle loading trays on the second floor of the three-story parking garage is a charging tray, each lifting and transverse charging tray can be respectively configured with a charging device as shown in Figure 4 or Figure 9.

[0126] In this way, when the fourth user needs to park their fourth vehicle on any of the vacant lifting and transversely moving charging trays on the second-floor parking spaces for charging, the parking garage can first use the transverse motor to adjust the position of the transversely moving vehicle loading trays below to free up parking spaces below. The lifting motor then lowers the lifting and transversely moving charging tray selected by the fourth user to the first floor, allowing the fourth user to enter the lifting and transversely moving charging tray. The user then manipulates the aforementioned rotating support mechanism to rotate the charging gun to the side of the fourth vehicle's charging port. Afterwards, the fourth user can park the fourth vehicle on the lifting and transversely moving charging tray and insert the charging gun into the fourth vehicle's charging port, completing the parking and charging process.

[0127] Afterwards, when the fifth user needs to park his fifth vehicle on any vacant lifting pallet on the third-floor parking space, or retrieve the fifth vehicle from the third-floor parking space above, the multi-story parking garage can first use the lifting motor to raise the lifting and transversely moving charging pallet where the fourth vehicle is parked to the second-floor parking position, and then use the transverse moving motor to laterally adjust the positions of each transversely moving pallet on the first floor and each lifting and transversely moving pallet on the second floor to free up the parking space below, and then use the lifting motor to lower the lifting pallet where the fifth vehicle needs to be parked or retrieved to the first floor for the fifth user to enter the lifting pallet.

[0128] Afterwards, when the fourth user needs to retrieve his fourth vehicle, the multi-story parking garage can first use the lifting motor to raise the lifting vehicle loading tray where the fifth vehicle is parked to the third-floor parking position, and then use the transverse motor to laterally adjust the position of each transverse vehicle loading tray on the first floor to free up the parking space below, and then use the lifting motor to lower the lifting and transverse charging tray carrying the fourth vehicle to the first floor, so that the fourth user can enter the lifting and transverse charging tray and drive away his parked fourth vehicle.

[0129] It should be noted that, due to the use of the charging device shown in Figures 4 or 9, the fourth vehicle can remain charged during the lifting and lateral movement, and the corresponding charging cable can also maintain a reasonable and controllable motion trajectory within the constraints of the lifting and lateral movement drag chains. Therefore, a stereo garage equipped with the above-mentioned charging device not only has higher charging efficiency, but also effectively overcomes the problem of cable entanglement and breakage caused by excessive bending, thereby improving the charging safety and service life of the stereo garage.

[0130] Furthermore, in other multi-story parking garages with more than three floors (for example, five floors) of parking spaces, each vehicle pallet on the first floor must have at least a transverse movement function, each vehicle pallet on the second to fourth floors must have both a lifting function and a transverse movement function, and each vehicle pallet on the fifth floor must have at least a lifting function. If at least one of the vehicle pallets on the second to fourth floors is a charging pallet, it can respectively include a pallet body 4541 with the above-mentioned first conductive member 101 and a pallet frame 4542 with the above-mentioned second conductive member 102, and each be equipped with a charging device as shown in Figures 10A to 10B. Correspondingly, if at least one of the vehicle pallets on the fifth floor is a charging pallet, it can also respectively include a pallet body with the above-mentioned first conductive member and a pallet frame with the above-mentioned second conductive member, and replace the original lifting and dragging chain with the first conductive member and the second conductive member.

[0131] As described above, due to the use of a transverse drag chain, and the above-mentioned first and second conductive members, the vehicle can maintain a charging state during the lateral movement after the lifting is completed, and the corresponding charging cable can also maintain a reasonable and controllable motion trajectory under the restriction of the transverse drag chain. Furthermore, due to the elimination of the lifting drag chain, the charging device shown in Figures 10A to 10B can effectively avoid the interference of the upper lifting drag chain on the lower charging device. Therefore, the three-dimensional parking garage equipped with the above-mentioned charging device not only has a higher charging efficiency, but also can further overcome the problem of the charging cable of the upper tray being entangled in the lower tray frame, and the problem of breakage caused by excessive bending of the cable, thereby improving the charging safety and service life of the three-dimensional parking garage.

[0132] Furthermore, in some embodiments of the present invention, the above-mentioned three-dimensional parking garage can also be configured as an intelligent parking garage, which can preferably include a second human-computer interaction interface and a second controller. Here, the second human-computer interaction interface may include a QR code provided on the charging gun seat or the vehicle loading tray, or an operating console (for example, a touch screen or button) provided on the outer surface of the three-dimensional parking garage, for obtaining parking instructions, vehicle pickup instructions and / or charging instructions provided by the user. The second controller can be configured on the charging pile or cloud of the charging device, and is used to control each vehicle loading tray to lift and / or move horizontally according to the instructions provided by the second human-computer interaction interface, and / or control the corresponding power supply to charge the electric vehicle.

[0133] Specifically, in the aforementioned smart parking garage embodiment, each charging gun holder or vehicle loading tray can be configured with a different QR code, and each QR code matches a corresponding charging station. When a user parks their vehicle on the vehicle loading tray, they can scan the QR code on the vehicle loading tray using a smart mobile device such as a smartphone, and the QR code is sent to a cloud-based charging control platform. After receiving the QR code, the cloud-based charging control platform can determine which charging station the user needs to use based on the target parking location of the vehicle loading tray. The centralized controller then sends a charging instruction to the charging station, causing it to charge the corresponding vehicle.

[0134] In addition, in the embodiments shown in Figures 12A to 12B, a baffle 595 may preferably be provided on the outer side of the charging gun seat along the edge of each vehicle loading pallet 111 to prevent the charging gun 52 and the active section of the charging cable connected to its end from extending beyond the parking position and interfering with or becoming entangled with the charging cable or the vertical garage frame of the adjacent parking space.

[0135] In summary, the above-mentioned electric vehicle charging device and multi-story parking garage provided by the present invention can raise the starting height of the movable section of the charging cable by fixing the fixed section of the charging cable, and rotate the charging gun to the side where the charging port of the electric vehicle is located, thereby shortening the distance from the charging gun to the charging interface, thereby reducing the length required for the movable section of the charging cable, thereby avoiding charging failures caused by cable entanglement and improving the service life of the charging cable.
