Description

[0001] This invention patent application is a divisional application of the invention patent application entitled “Charging device for electric vehicles and multi-story garage” with application number 202480002529.9 and application date August 12, 2024. Technical Field

[0002] 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 car park. Background Art

[0003] As an important means of transportation for people's daily life, the number of cars is increasing year by year. In order to cope with the increasingly serious parking problem, various parking equipment has emerged. The lifting and transverse moving stereo garage is a parking equipment that stores and retrieves cars by lifting and transversely moving the car tray. It has a very high space utilization rate and is therefore widely used in shopping malls, hospitals, office parks, bus hubs and other places with dense traffic.

[0004] In addition, as my country's automobile industry gradually transforms towards new energy vehicles, the types and numbers of electric vehicles are increasing rapidly, and the locations of their charging ports are also varied. 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 three-dimensional parking garage contains multiple parking spaces, it is necessary to frequently lift and shift the vehicle pallet 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 three-dimensional parking garage, resulting in damage and breakage of the gun cable during the lifting and shifting of the vehicle pallet, and ultimately causing charging failures.

[0005] In order to overcome the above problems, the art has proposed a variety of vehicle charging solutions based on cable reels, which can release the corresponding length of the gun wire according to the distance of the charging port, and recycle the gun wire in time after charging is completed to avoid entanglement with other charging gun wires or adjacent equipment, and 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 gun wire continues to increase, and its corresponding maximum bending radius also continues to increase. This vehicle charging solution based on a cable reel not only requires frequent bending of the charging gun wire, but also has the problem of too small bending radius in the central area. Therefore, it is very easy to cause damage and breakage due to frequent and excessive bending of the gun wire, and affect the service life of the charging gun wire.

[0006] In order to overcome the above-mentioned defects of the prior art, the art urgently needs an improved vehicle charging solution by reducing the distance from the charging gun to the charging port and reducing 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. Summary of the invention

[0007] A brief summary of one or more aspects is given below to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all conceived aspects, and is neither intended to identify the key or decisive elements of all aspects nor to define the scope of any or all aspects. Its only purpose is to give some concepts of one or more aspects in a simplified form as a prelude to a more detailed description that will be given 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 car park, which can raise the starting height of the active 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 and reducing 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.

[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 flexibly connect the charging gun.

[0010] In addition, the above-mentioned three-dimensional parking garage provided according to the second aspect of the present invention includes M*N parking positions, M*Ni vehicle loading trays, and at least one charging device for the above-mentioned electric vehicle provided according to the first aspect of the present invention.

[0024] The following specific embodiments illustrate the implementation of the present invention, and 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 implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation 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 clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In addition, the terms "upper", "lower", "left", "right", "top", "bottom", "horizontal" and "vertical" used in the following description should be understood as the directions shown in the paragraph and the related drawings. Such relative terms are only used for the convenience of description and do not mean that the device described therein must be manufactured or operated in a specific direction, and therefore should not be understood as limiting the present invention.

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

[0028] As mentioned above, since the multi-story parking garage contains multiple parking spaces, the vehicle pallets need to be frequently lifted and moved horizontally to meet the needs of parking and picking up vehicles. 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 damage and breakage of the gun line during the lifting and moving of the vehicle pallet, and ultimately causing charging failure.

[0029] Furthermore, although the art has proposed a variety of vehicle charging solutions based on cable reels, which can release the corresponding length of the cable according to the distance of the charging port, and recycle the cable in time 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. However, 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 vehicle charging solution based on a cable reel not only requires frequent bending of the charging cable, but also has the problem of too small bending radius in the central area. Therefore, it is very easy to cause damage and breakage due to frequent and excessive bending of the cable, and affect 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 car park, which can raise the starting height of the active 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 and reducing 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.

[0031] First, please refer to Figure 1 , Figure 1 A schematic structural diagram of a charging device for an electric vehicle provided according to some embodiments of the present invention is shown.

[0032] exist Figure 1 In the illustrated embodiment, the charging device for the electric vehicle provided in the first aspect of the present invention includes a power source, a charging gun 12, a rotating support mechanism and a charging cable. Here, the power source can be a DC power source or an AC power source, which is integrated into the charging pile 11 of the charging device to provide electrical energy to the electric vehicle via the charging cable and the charging gun 12. The charging gun 12 is provided at the end of the charging cable and is used to plug into the charging port of the electric vehicle to charge it.

[0033] The rotating support mechanism can be arranged behind the parking position, and is used 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 the distance to the charging port of various types of electric vehicles, thereby reducing the required length of the active section of the charging cable.

[0034] The two ends of the charging cable are connected to the power source and the charging gun 12 respectively, and are divided into a fixed section 141 and a movable section (i.e., the charging gun line) 142. Here, the fixed section 141 is fixed to the rotating support mechanism and extends along it to a preset first height, while the movable section 142 is separated from the rotating support mechanism from the first height to be movably connected to the charging gun 12.

[0035] Furthermore, in some embodiments, the first height may be comparable to the height of the charging port of the electric vehicle. Specifically, the technician may determine the first height based on the height of the charging port of at least one charging vehicle. For example, the technician 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, the technician may also assign a greater weight coefficient to the height of the charging port 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, if Figure 1 As shown, 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 warehouse 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 active 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 active 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, so as to rotate and move the charging gun 12 carried by it 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 the 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, 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.

[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] In this way, by reducing the distance between the charging gun 12 and the charging port in the plane and vertical direction, the required length of the active section 142 of the charging cable is reduced, and the length is limited to be less than the above-mentioned first height. The present invention can further avoid charging failures caused by cable entanglement, and avoid the risk of electric shock caused by the charging gun 12 and the charging cable accidentally falling to the ground or the vehicle tray 151. In addition, by using the rocker arm 132 to set and rotate the charging gun seat 16 to a position close to the charging port inside the parking position, the user can complete all operations for charging the vehicle on the spot without crossing the vehicle tray 151, thus having higher safety and convenience.

[0042] Further, in some embodiments, the charging gun seat 16 may include a telescopic mechanism (e.g., a spring balancer) and a hook. Here, the telescopic mechanism may be provided at the end of the rocker arm 132 and elastically connected to the hook carrying the charging gun 12, which can be extended under the pulling force of the user to allow the charging gun to descend and plug into the charging port of the electric vehicle. Afterwards, when the user pulls out the charging gun 12 after completing the charging, the telescopic mechanism may rebound after losing the pulling force provided by the user and the charging port, so that the charging gun 12 is automatically recovered to the end of the rocker arm 132. In this way, the present invention can effectively prevent the sagging charging gun 12 from getting entangled with other cables and garage frames, and prevent it from colliding with vehicles or vertical garage frames parked in the parking space and adjacent parking spaces when moving the vehicle tray 151 left and right. Compared with the prior art of using a reel to recycle the charging cable, the telescopic mechanism does not involve winding the charging cable. On the one hand, it can effectively avoid the entanglement of the charging cable to affect its normal extension and contraction, and on the other hand, it can avoid frequent and excessive bending of the charging cable to 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 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 the charging gun 12 and the vehicles parked in the current parking space and the adjacent parking space or the frame of the vertical garage when the vehicle loading tray is moved 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 use 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 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 letting 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, a touch screen or a 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 location 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 shaft 131.

[0048] Furthermore, for the charging device used in the 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, it can be raised and lowered and / or moved laterally between multiple parking positions in the stereo garage.

[0049] Please refer to Figure 2 to Figure 4 . Figure 2 A schematic structural diagram of a charging device with a lateral movement function provided according to some embodiments of the present invention is shown. Figure 3 A schematic structural diagram of a charging device with a lifting function provided according to some embodiments of the present invention is shown. Figure 4A schematic structural diagram of a charging device with lateral movement and lifting functions provided according to some embodiments of the present invention is shown.

[0050] exist Figure 2 In the illustrated embodiment, for the 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 limit groove 171, which extends along the transverse direction of the vehicle tray 152, and at least one side thereof (for example, the upper side, the lower side, the front side, and 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 limit bending radius of the charging cable, and its first end is fixed to the first position of the transverse limit groove 171 (for example, the right side), and its second end is fixed to the second position of the vehicle tray 152 (for example, the middle of the rear side), and is inserted into the transverse limit groove 171 through the first strip-shaped opening as the vehicle tray 152 moves transversely to the left, or is dragged out of the transverse limit groove 171 through the first strip-shaped opening as the vehicle tray 152 moves transversely to the right.

[0052] The first end of the fixed section 141 of the charging cable is connected to the power supply in the charging pile 11, and 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 embedded in the transverse limiting groove 171 or dragged out of the transverse limiting groove 171 with the transverse movement of the vehicle loading tray 152 under the restriction of the transverse drag chain 181, so as to maintain the charging of the electric vehicle during the transverse movement of the vehicle loading tray 152, avoid entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical warehouse frame, resulting in cable damage or garage alarm, and avoid damage or breakage due to excessive bending.

[0053] In addition, Figure 3 In the illustrated embodiment, 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 (for example, the front side, the rear side, the left side, and the right side) is provided with a second strip opening extending along the lifting direction. The bending radius of the lifting drag chain 182 is greater than the limit bending radius of the charging cable, and its first end is fixed to the first position of the longitudinal limit groove 172 (for example, the upper side), and its second end is fixed to the second position of the vehicle tray 153 (for example, the middle of the rear side), and is embedded in the longitudinal limit groove 172 through the second strip opening as the vehicle tray 153 moves downward longitudinally, or is dragged out of the longitudinal limit groove 172 through the second strip opening as the vehicle tray 153 moves upward longitudinally.

[0055] The first end of the fixed section 141 of the charging cable is connected to the power supply in the charging pile 11, and the second end thereof extends into the lifting and dragging chain 182 through the above-mentioned first position, and extends out of the lifting and dragging chain 182 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 153. In this way, the fixed section 141 of the charging cable can be embedded in the longitudinal limit groove 172 or dragged out of the longitudinal limit groove 172 with the longitudinal movement of the vehicle loading tray 153 under the restriction of the lifting and dragging chain 182, so as to maintain the charging of the electric vehicle during the longitudinal movement of the vehicle loading tray 153, avoid entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical warehouse frame, resulting in cable damage or garage alarm, and avoid damage or breakage due to excessive bending.

[0056] Those skilled in the art will appreciate that the longitudinal limit groove 172 is only a non-limiting implementation of 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 tray 153 that only has the lifting function, the above-mentioned charging device may also only include a lifting drag chain 182, but not 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 three-dimensional parking 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 tray 153 descends, or bend upward as the vehicle tray 153 rises, so it will not be entangled with the charging cables of other charging parking spaces and / or equipment such as the three-dimensional 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.

[0058] In addition, Figure 4In the illustrated embodiment, 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 may be a transverse limit groove 173. The vehicle loading pallet may 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 a lifting function and a transverse movement function, and 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 to be embedded in the pallet frame 1542, and then move transversely with the pallet frame 1542.

[0060] The transverse limiting groove 173 extends along the transverse direction of the vehicle loading tray, and at least one side thereof (e.g., the upper side, the lower side, the front side, and the rear side) is provided with a first strip-shaped opening extending along the transverse direction. The bending radius of the transverse drag chain 183 is greater than the limit bending radius of the charging cable, and its first end is fixed to the first position (e.g., the right side) of the transverse limiting groove 173, and its second end is fixed to the second position (e.g., the middle of the rear side) of the tray frame 1542, and is inserted into the transverse limiting groove 173 through the first strip-shaped opening as the tray frame 1542 moves transversely to the left, or is dragged out of the transverse limiting groove 173 through the first strip-shaped opening as the tray frame 1542 moves transversely to the right. The bending radius of the lifting drag chain 184 is also larger 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 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 11, and the second end thereof extends into the transverse drag chain 183 via the above-mentioned first position, and extends 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 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 embedded in the transverse limit groove 173 or dragged out of the transverse limit groove 173 as the pallet frame 1542 moves horizontally under the restriction of the transverse drag chain 183, thereby maintaining the charging of the electric vehicle during the horizontal movement of the vehicle-carrying pallet, avoiding entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical warehouse frame, resulting in cable damage or garage alarm, and avoiding damage or breakage due to excessive bending. The second fixed section of the charging cable can be unfolded downward or bent upward 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 warehouse frame, resulting in cable damage or garage alarm, and avoiding damage or breakage due to excessive bending.

[0063] Those skilled in the art will understand that Figure 2 and Figure 4 The shown transverse limit grooves 171, 173 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, 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 the parking space with the charging cables of other charging spaces and / or equipment such as the 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 can also understand that Figure 1 to Figure 4 The charging devices shown are only some non-limiting embodiments provided by the present invention, which are intended to clearly illustrate 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.

[0066] In addition, please continue to refer to Figure 5 to Figure 7 . Figure 5 A schematic structural diagram of a horizontally rotating charging device provided according to some embodiments of the present invention is shown. Figure 6 A schematic structural diagram of a vertically rotating charging device provided according to some embodiments of the present invention is shown. Figure 7 A schematic structural diagram of a charging device with a lateral movement function provided according to some embodiments of the present invention is shown.

[0067] exist Figure 5In the illustrated embodiment, the above-mentioned rotating support mechanism may include a rotating shaft 231, a rocker arm 232, a vertical pole 233 and a charging gun seat 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 be driven by the rotating shaft 231 to rotate horizontally 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 seat 26 for carrying an idle charging gun 22. The length of the active section 242 of the charging cable is less than the first height, and it extends out of the second end of the vertical pole 233, so that the user can 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 seat 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, and after charging is completed, plug the charging gun 22 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 holder 26 at the end of the pole 233.

[0070] In this way, by reducing the distance between the charging gun 22 and the charging port in the plane and vertical direction, the required length of the active section 242 of the charging cable is reduced, and the length is limited to be less than the above-mentioned first height. The present invention can further avoid charging failures caused by cable entanglement, and avoid the risk of electric shock caused by the charging gun 22 and the charging cable accidentally falling to the ground or the vehicle tray 25. In addition, by using the rocker 232 to set and rotate the charging gun seat 26 to a position close to the charging port inside the parking position, the user can complete all operations for charging the vehicle on the spot without crossing the vehicle tray 25, thus having higher safety and convenience.

[0071] Furthermore, if Figure 5As shown, the charging gun seat 26 can be arranged toward the outside of the vehicle tray 25, so that the direction of the charging gun 22 plugged into the charging gun socket 26 is consistent with the direction of the charging gun plugged into the vehicle charging port, so that the user can observe the position of the charging gun 22 and it is convenient for the user to quickly locate and use the charging gun 22. In addition, the charging gun seat 26 can be configured as an elastic hook with a telescopic function, which is used to extend under the pulling force of the user to allow the charging gun 22 to be plugged into the charging port of the electric vehicle, and rebound after losing the pulling force provided by the user and the charging port, so that the charging gun 22 is automatically recovered to the end of the rotating support mechanism, thereby avoiding the entanglement of the sagging charging gun with other cables and the garage frame, and avoiding it from colliding with the vehicles or the garage frame parked in the parking space and the adjacent parking space when the vehicle tray is moved left and right.

[0072] In addition, in some embodiments, an insulating connector 291 may be further 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 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 warehouse. 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 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 a rotating space for the rocker arm 232 behind the vehicle tray 25, so as to achieve a compact design of the parking position.

[0075] In addition, Figure 6In the illustrated embodiment, the above-mentioned rotating support mechanism may include a rotating shaft 331, a rocker arm 332, a vertical pole 333, a cross bar 334 and a charging gun seat 36. Specifically, the vertical pole 333 can be vertically installed on the rear edge of the vehicle loading tray 35 in the parking position. The rotating shaft 331 is horizontally installed at the first height of the vertical pole 333. The rocker arm 332 can be vertically rotated under the drive of the rotating shaft 331 to rotate and move the charging gun 32 carried by it to the side where the charging port of the electric vehicle is located. The first end of the cross bar 334 is connected to the second end of the rocker arm 332, and the second end thereof extends forward to the charging port of the electric vehicle, and is provided with a charging gun seat 36 for carrying an idle charging gun 32. The length of the active section 342 of the charging cable is less than the first height, and it extends out of the second end of the cross bar 334, so that the user can plug the charging gun 32 at its end into the charging port of the electric vehicle nearby, and plug it back into the charging gun seat 36 nearby after charging is completed.

[0076] For example, when the charging port of the electric vehicle is on its left side, the user can vertically rotate the rocker arm 332 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, and after charging is completed, plug the charging gun 32 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, so as to plug the electric gun 32 into the charging port on the right side of the electric vehicle, and after charging is completed, plug the charging gun 32 back into the charging gun seat 36 at the end of the cross bar 334.

[0078] In this way, by reducing the distance from the charging gun 32 to the charging port from the front, rear, left, right, top, and bottom six directions, the required length of the active section 342 of the charging cable is reduced, and the length is limited to be less than the above-mentioned first height. The present invention can further avoid charging failures caused by cable entanglement, and avoid the risk of electric shock caused by the charging gun 32 and the charging cable accidentally falling to the ground or the vehicle tray 35. In addition, by using the rocker arm 332 to set and rotate the charging gun seat 36 to a position close to the charging port inside the parking position, the user can complete all operations for charging the vehicle on the spot without crossing the vehicle tray 35, thus having higher safety and convenience.

[0079] Furthermore, if Figure 6As shown, the charging gun seat 36 can be arranged toward the outside of the vehicle tray 35, so that the direction of the charging gun 32 plugged into the charging gun socket 36 is consistent with the direction of the charging gun plugged into the vehicle charging port, so that the user can observe the position of the charging gun 32 and it is convenient for the user to quickly locate and use the charging gun 32. In addition, the charging gun seat 36 can be configured as an elastic hook with a telescopic function, which is used to extend under the pulling force of the user to allow the charging gun 32 to be plugged into the charging port of the electric vehicle, and rebound after losing the pulling force provided by the user and the charging port, so that the charging gun 32 is automatically recovered to the end of the rotating support mechanism, thereby avoiding the entanglement of the sagging charging gun with other cables and the garage frame, and avoiding it from colliding with the vehicles or the garage frame parked in the parking space and the adjacent parking space when the vehicle tray is moved left and right.

[0080] In addition, in some embodiments, an insulating connector 391 may be further provided between the vertical pole 333 and the vehicle loading tray 35 for insulating and isolating 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 space ground lock may be provided in the middle of the vehicle loading tray 35. The control line of the parking space 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 enables the charging function, the first controller may send an unlocking command to the parking space 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 space 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 space ground lock of the lifting and transverse shifting tray.

[0082] In addition, in some embodiments, an anti-return 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 during the process of backing into the warehouse. Furthermore, the sixth height of the anti-return beam 393 may be less than the fifth height of the vehicle chassis to prevent interference with the vehicle chassis.

[0083] In addition, Figure 7In the illustrated embodiment, the above-mentioned rotating support mechanism may include a rotating shaft 431 and a rocker arm 432, and a charging gun seat 461 and 462 may be provided on both sides of the rear of the parking position. Specifically, the rotating shaft 431 may be vertically mounted on the rear edge of the vehicle tray 451 at the parking position, and its fourth height is less than the fifth height of the chassis of the electric vehicle to ensure that the rocker arm 432 rotating in the direction toward the vehicle tray 451 will not collide with the electric vehicle parked in the parking space. The rocker arm 432 may be driven by the rotating shaft 431 to rotate horizontally at the fourth height to rotate the charging gun carried by it horizontally to the side where the charging port of the electric vehicle is located. The active section 442 of the charging cable extends out of the second end of the rocker arm 432 at the fourth height, so that the user can plug the charging gun at its end into the charging port of the electric vehicle nearby, and plug it back into the charging gun seat 461 or 462 on the nearby side after charging is completed.

[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] In this way, by reducing the distance from the charging gun to the charging port in the plane direction, the required length of the charging cable movable section 442 is reduced, and the present invention can effectively avoid charging failures caused by cable entanglement. In addition, by using the swing arm 432 to rotate and move the idle charging gun to a position close to the charging port inside the parking position, the user can complete all operations of charging the vehicle on the spot without crossing the vehicle loading tray 451, thus having higher 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 seats 461, 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 tray 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 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 warehouse. 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 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 further reserve the rotation space of the rocker arm 432 behind the vehicle tray 451 to achieve a compact design of the parking position.

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

[0091] like Figure 7 As shown, for the vehicle loading tray 451 having only the 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 limit groove 471, which extends along the transverse direction of the vehicle tray 451, and at least one side thereof (for example, the upper side, the lower side, the front side, and 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 limit bending radius of the charging cable, and its first end is fixed to the first position of the transverse limit groove 471 (for example, the right side), and its second end is fixed to the second position of the vehicle tray 451 (for example, the middle of the rear side), and is embedded in the transverse limit groove 471 through the first strip-shaped opening as the vehicle tray 451 moves transversely to the left, or is dragged out of the transverse limit groove 471 through the first strip-shaped opening as the vehicle tray 451 moves transversely to the right.

[0093] The first end of the fixed section 441 of the charging cable is connected to the power supply in the charging pile 41, and 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 embedded in the transverse limiting groove 471 or dragged out of the transverse limiting groove 471 with the transverse movement of the vehicle loading tray 451 under the restriction of the transverse drag chain 481, so as to maintain the charging of the electric vehicle during the transverse movement of the vehicle loading tray 451, avoid entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical warehouse frame, resulting in cable damage or garage alarm, and avoid damage or breakage due to excessive bending.

[0094] In addition, please refer to Figure 8 , Fig. 9 and Figure 10A to Figure 10B . Figure 8 A schematic structural diagram of a charging device with a lifting function provided according to some embodiments of the present invention is shown. Fig. 9 A schematic structural diagram of a charging device with lateral movement and lifting functions provided according to some embodiments of the present invention is shown. Figures 10A to 10B A schematic structural diagram of a charging device with lateral movement and lifting functions provided according to some embodiments of the present invention is shown.

[0095] exist Figure 8 In the illustrated embodiment, 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 at least one side thereof (for example, the front side, the rear side, the left side, and the right side) is provided with a second strip-shaped opening extending along the lifting direction. The bending radius of the lifting drag chain 482 is greater than the limit bending radius of the charging cable, and its first end is fixed to the first position (for example, the upper side) of the longitudinal limit groove 472, and its second end is fixed to the second position (for example, the middle of the rear side) of the vehicle tray 452, and is embedded in the longitudinal limit groove 472 through the second strip-shaped opening as the vehicle tray 452 moves downward longitudinally, or is dragged out of the longitudinal limit groove 472 through the second strip-shaped opening as the vehicle tray 452 moves upward longitudinally.

[0097] The first end of the fixed section 441 of the charging cable is connected to the power supply in the charging pile 41, and the second end thereof extends into the lifting and dragging chain 482 through the above-mentioned first position, and extends out of the lifting and dragging chain 482 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 452. In this way, the fixed section 441 of the charging cable can be embedded in the longitudinal limit groove 472 or dragged out of the longitudinal limit groove 472 with the longitudinal movement of the vehicle loading tray 452 under the restriction of the lifting and dragging chain 482, so as to maintain the charging of the electric vehicle during the longitudinal movement of the vehicle loading tray 452, avoid entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical warehouse frame, resulting in cable damage or garage alarm, and avoid damage or breakage due to excessive bending.

[0098] In addition, in other embodiments, for the vehicle tray 452 that only has the lifting function, the above-mentioned charging device may also only include the lifting drag chain 482, but not the longitudinal limit groove 472. At this time, the first end of the lifting drag chain 482 can be fixed to the sixth position of the three-dimensional parking 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 unfolded downward as the vehicle tray 452 descends, or bend upward as the vehicle tray 452 rises, so it will not be entangled with the charging cables of other charging parking spaces and / or equipment such as the three-dimensional garage frame, causing cable damage or garage alarm, and it can also prevent the charging cable from being damaged or broken due to excessive bending.

[0099] In addition, Fig. 9 In the illustrated embodiment, 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 limit 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 a lifting function and a transverse movement function, and 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 to be embedded in the pallet frame 4542, and then move transversely with the pallet frame 4542.

[0101] The transverse limiting groove 473 extends along the transverse direction of the vehicle loading tray, and at least one side thereof (e.g., upper side, lower side, front side, rear side) is provided with a first strip-shaped opening extending along the transverse direction. The bending radius of the transverse drag chain 483 is greater than the limit bending radius of the charging cable, and its first end is fixed to the first position of the transverse limiting groove 473 (e.g., right side), and its second end is fixed to the second position of the tray frame 4542 (e.g., middle of the rear side), and is inserted into the transverse limiting groove 473 through the first strip-shaped opening as the tray frame 4542 moves transversely to the left, or is dragged out of the transverse limiting groove 473 through the first strip-shaped opening as the tray frame 4542 moves transversely to the right. The bending radius of the lifting drag chain 484 is also larger 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 sections of the 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 embedded in the transverse limit groove 473 or dragged out of the transverse limit 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-carrying pallet, avoiding entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical warehouse frame, resulting in cable damage or garage alarm, and avoiding 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-carrying pallet, avoiding entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical warehouse frame, resulting in cable damage or garage alarm, and avoiding damage or breakage due to excessive bending.

[0104] In addition, Figure 10A to Figure 10BIn the illustrated embodiment, for a vehicle-carrying pallet having both lateral movement and lifting functions, the lifting and lowering drag chain 484 in the above embodiment may also be replaced by a docking mechanism.

[0105] Specifically, only the seventh drag chain support and the transverse drag chain 483 need to be configured in the charging device. 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 a second conductive member 102 is provided at its fifth position. The tray body 4541 has both lifting and transverse movement functions, and a first conductive member 101 is provided at its fourth position, 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, so as to realize the 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., right side) of the transverse limit groove 473, and the second end thereof is fixed to the second position (e.g., 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 is 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 source 41, and the second end thereof extends into the transverse drag chain 483 via the above-mentioned first position, and extends from the transverse drag chain 483 from the above-mentioned second position to be fixedly connected to its first conductive member 101 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] Further, in some embodiments, the first conductive member 101 may include a first supporting structure, a first elastic buffer structure and a first conductor. Here, the first supporting structure is disposed at a fourth position on the tray body 4541, and is used to support the first elastic buffer structure. The first end of the first elastic buffer structure is connected to the first supporting structure, and the second end thereof is connected to the first conductor, and is used to fine-tune the relative position of the first conductor to improve the success rate of docking with the second conductive member 102, and deform when the tray body 4541 is embedded in the tray frame 4542, so as to reduce the contact resistance between the first conductive member 102 and the second conductive member 102.

[0108] In addition, in some embodiments, the second conductive member 102 may include a second supporting structure, a second elastic buffer structure, and a second conductive body. Here, the second supporting structure is disposed at the fifth position on the tray frame 4542, and is used to support the second elastic buffer structure. The first end of the second elastic buffer structure is connected to the second supporting structure, and the second end thereof is connected to the second conductive body, and is used to fine-tune the relative position of the second conductive body to improve the success rate of docking with the first conductive member 101, and deforms when the tray body 4541 is embedded in the tray frame 4542, so as to reduce the contact resistance between the second conductive body and the first conductive member 101.

[0109] Compared to Fig. 9 The embodiment shown, Fig. 10A and 10B The docking mechanism used in the illustrated embodiment can effectively avoid the interference of the sagging lifting and lowering drag chain 484 with the parking position on the lower floor, and is therefore more suitable for application in three-story or higher stereo garages. In addition, since the third fixed section of the charging cable can still be inserted into the transverse limit groove 473 or dragged out of the transverse limit groove 473 with the transverse movement of the pallet frame 4542 under the restriction of the transverse drag chain 483, the solution can still maintain the charging of the electric vehicle during the transverse movement of the vehicle pallet, avoiding entanglement with the charging cables of other charging parking spaces and / or equipment such as the vertical garage frame, resulting in cable damage or garage alarm, and avoiding damage or breakage due to excessive bending.

[0110] It will be appreciated by those skilled in the art that although the foregoing only illustrates and describes the Figure 7 The drag chain support, transverse drag chains 481, 483, lifting drag chain 482, vehicle loading tray body 4541, vehicle loading tray frame 4542, and related embodiments of the conductive members 101, 102 of the rotating support mechanism shown are only a non-restrictive description method intended to clearly demonstrate the main concept of the present invention rather than to limit the scope of protection of the present invention.

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

[0112] In addition, according to the second aspect of the present invention, a three-dimensional parking garage is provided, which includes M*N parking positions, M*Ni vehicle loading trays, and at least one charging device for the electric vehicle as provided in the first aspect of the present invention. Here, M is the number of parking positions 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 positions.

[0113] Further, please refer to Fig.11 and Figure 12A to Figure 12B . Fig.11 A schematic structural diagram of a stereoscopic car park provided according to some embodiments of the present invention is shown. Figures 12A to 12B A schematic structural diagram of the first floor of a three-dimensional parking garage provided according to some embodiments of the present invention is shown.

[0114] exist Fig.11 and Figure 12A to Figure 12B In the illustrated embodiment, this article discloses a double-layer, five-parking-space stereoscopic charging garage, wherein the first layer has three parking positions and is provided with two transverse vehicle pallets 111 with only transverse movement function, and the second layer also has three parking positions and is provided with three lifting vehicle pallets 112 with only lifting function.

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

[0116] Thus, when the first user needs to park his first vehicle on any of the transverse charging trays 111 in the first-floor parking spaces for charging, he can manipulate the above-mentioned 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 to complete the parking charging operation 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 use the transverse motor to laterally adjust the positions of the transverse charging trays 111 below to vacate 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 Figure 2 , Figure 5 , Figure 6 or Figure 7 With the charging device shown, the first vehicle can always keep charging during the lateral movement, and the corresponding charging cable can also maintain a reasonable and controllable motion trajectory under the restriction of the lateral drag chain. Therefore, the stereo garage equipped with the above charging device not only has higher charging efficiency, but also can effectively overcome 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 of the second layer can be configured as a charging tray, and each of them is provided with a charging device. Here, the charging device can be selected to adapt to the specific structure of the rotating support mechanism. Figure 3 or Figure 8 The scheme shown.

[0120] In this way, when the second user needs to park his second vehicle on any free lifting charging tray 112 in the second-floor parking space for charging, the three-dimensional parking garage can first adjust the position of each lateral vehicle loading tray 111 below via the lateral motor to vacate the parking space below, and then lower the lifting charging tray 112 selected by the second user to the first floor via the lifting motor, so that the second user can enter the lifting 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 lifting charging tray 112 and insert the charging gun into the charging port of the second vehicle to complete the parking charging operation process.

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

[0122] It should be noted that due to the use of Figure 3 or Figure 8With the charging device shown, the second vehicle can always be charged during the lifting process, and the corresponding charging cable can also maintain a reasonable and controllable motion trajectory under the restriction of the lifting drag chain. Therefore, the three-dimensional parking garage equipped with the above charging device not only has higher charging efficiency, but also can effectively overcome 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 Fig.11 and Figure 12A to Figure 12B The double-layer, five-bay stereoscopic charging garage shown are only some non-limiting embodiments 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 some 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 transversely movable vehicle loading pallets of the first-story parking space of the three-story stereo garage is a charging pallet, each transversely movable charging pallet can be respectively configured with a Figure 2 , Figure 5 , Figure 6 or Figure 7 When at least one of the M lifting vehicle loading trays on the third parking space of the three-story stereo garage is a charging tray, each lifting charging tray can be respectively configured with a charging device such as Figure 3 or Figure 8 When at least one of the M-1 lifting and transversely movable vehicle loading trays of the second-story parking space of the three-story stereo garage is a charging tray, each lifting and transversely movable charging tray can be respectively configured with a Figure 4 or Fig. 9 The charging device shown.

[0126] In this way, when the fourth user needs to park his fourth vehicle on any free lifting and transversely moving charging tray in the second-floor parking space for charging, the three-dimensional parking garage can first adjust the position of each transversely moving vehicle loading tray horizontally through the transverse moving motor to vacate the parking space below, and then lower the lifting and transversely moving charging tray selected by the fourth user to the first floor through the lifting motor to allow the fourth user to enter the lifting and transversely moving charging tray, and rotate the charging gun to the side where the charging port of the fourth vehicle is located by manipulating the above-mentioned rotating support mechanism. Afterwards, the fourth user can park the fourth vehicle on the lifting and transversely moving charging tray and insert the charging gun into the charging port of the fourth vehicle to complete the parking and charging operation process.

[0127] Afterwards, when the fifth user needs to park his fifth vehicle at any vacant lifting vehicle pallet on the third-floor parking space, or retrieve the fifth vehicle from the third-floor parking space above, the three-dimensional parking garage can first use the lifting motor to raise the lifting and transverse 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 transverse moving vehicle pallet on the first floor and each lifting and transverse moving vehicle pallet on the second floor to free up the parking space below, and then use the lifting motor to lower the lifting vehicle pallet where the fifth vehicle needs to be parked or retrieved to the first floor for the fifth user to enter the lifting vehicle 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 lift the lifting vehicle pallet that parks the fifth vehicle to the third-floor parking position, and then use the transverse motor to laterally adjust the position of each transverse vehicle pallet on the first floor to vacate the parking space below, and then use the lifting motor to lower the lifting and transverse charging pallet carrying the fourth vehicle to the first floor, so that the fourth user can enter the lifting and transverse charging pallet and drive away his parked fourth vehicle.

[0129] It should be noted that due to the use of Figure 4 or Fig. 9 With the charging device shown, the fourth vehicle can always keep charging during the lifting and lateral movement, and the corresponding charging cable can also maintain a reasonable and controllable motion trajectory under the constraints of the lifting and lateral movement drag chains. Therefore, the three-dimensional parking garage equipped with the above charging device not only has higher charging efficiency, but also can effectively overcome 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.

[0130] Furthermore, in other three-dimensional 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 include a pallet body 4541 with the first conductive member 101 and a pallet frame 4542 with the second conductive member 102, and each is provided with a Figure 10A to Figure 10B Correspondingly, if at least one of the vehicle-carrying pallets on the fifth layer is a charging pallet, it may also include a pallet body with the first conductive member and a pallet frame with the second conductive member, and the first conductive member and the second conductive member may replace the original lifting and dragging chain.

[0131] As described above, due to the use of the transverse drag chain and the 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 movement trajectory under the restriction of the transverse drag chain. Figure 10A to Figure 10B The charging device shown 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 charging device not only has higher charging efficiency, but also can further overcome the problem of the charging cable of the upper tray getting entangled with the frame of the lower tray, and the problem of the cable breaking due to excessive bending, 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 also preferably include a second human-machine interaction interface and a second controller. Here, the second human-machine interaction interface may include a QR code set on the charging gun seat or the vehicle loading tray, or an operating table (for example: a touch screen or button) set on the outer surface of the three-dimensional parking garage, which is used to obtain 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-machine interaction interface, and / or control the corresponding power supply to charge the electric vehicle.

[0133] Specifically, in the above-mentioned embodiment of the smart parking garage, in this embodiment, each charging gun seat or vehicle tray can be configured with a different QR code, and each QR code matches a corresponding charging pile. When the user parks the vehicle on the vehicle tray, the QR code set on the vehicle tray can be scanned by a smart mobile terminal such as a smart phone, and the QR code is sent to the charging control platform in the cloud. After receiving the QR code, the cloud charging control platform can determine which charging pile the user needs to use for charging in combination with the target parking position of the vehicle tray, and then send a charging instruction to the charging pile through the centralized controller to charge the corresponding vehicle.

[0134] In addition, Figure 12A to Figure 12B In the illustrated embodiment, a baffle 595 may preferably be provided on the outer side of the charging gun seat along the edge of each vehicle loading tray 111 to prevent the charging gun 52 and the active section of the charging cable connected to its end from extending out of 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 car park provided by the present invention can raise the starting height of the active 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 and reducing 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.

[0136] Although the above methods are illustrated and described as a series of actions for simplicity of explanation, it should be understood and appreciated that these methods are not limited by the order of the actions, because according to one or more embodiments, some actions may occur in a different order and / or concurrently with other actions from those illustrated and described herein or not illustrated and described herein but understandable to those skilled in the art.

Various modifications to the disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure.
