Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging technology, and in particular to a charging device for electric vehicles. Background Technology

[0002] As an important means of transportation for people's daily lives, the number of cars on the road is increasing year by year. In order to cope with the increasingly serious parking problem, various parking facilities have emerged. The lift-and-slide automated parking system is a parking system that uses lifting and sliding vehicle pallets to store and retrieve cars. It has a very high space utilization rate and is therefore widely used in shopping malls, hospitals, office parks, public transportation hubs and other places with high traffic flow.

[0003] Furthermore, as my country's automotive industry gradually shifts towards new energy vehicles, the types and numbers of electric vehicles are rapidly increasing, and the locations of their charging ports vary considerably. To accommodate the charging needs of various vehicle models, existing charging stations typically feature long charging cables, allowing users to move the charging gun to any position within the parking space. However, because multi-level parking garages contain multiple parking spaces, frequent raising, lowering, and lateral movement of vehicle pallets are necessary to meet parking and retrieval needs. This long charging cable compatibility solution is highly susceptible to entanglement with other charging cables in adjacent parking spaces or with other equipment such as the garage's frame. This can lead to cable damage or breakage during the raising and lowering of vehicle pallets, ultimately causing charging malfunctions.

[0004] To overcome the aforementioned problems, various vehicle charging solutions based on cable reels have been proposed in this field. These solutions can release a cable of a corresponding length according to the distance to the charging port and promptly retract the cable after charging is complete to avoid entanglement with other charging cables or adjacent devices, and to meet the charging needs of vehicles in multiple parking spaces. However, with the continuous development of vehicle fast charging technology, the diameter of the charging cable is constantly increasing, and its corresponding maximum bending radius is also constantly increasing. This type of vehicle charging solution based on cable reels not only requires frequent bending of the charging cable, but also suffers from an excessively small bending radius in the central area. Therefore, it is very easy for the cable to break or fracture due to frequent and excessive bending, thus affecting the service life of the charging cable.

[0005] In order to overcome the above-mentioned defects in the existing technology, there is an urgent need in the field for an improved vehicle charging solution that reduces the distance between the charging pile and the charging interface, reduces the length required for the moving section of the charging gun cable, thereby avoiding charging failures caused by cable entanglement and improving the service life of the charging gun cable.

[0009] According to an embodiment of the present invention, the charging device for an electric vehicle, by fixing the power connection cable, raises the initial height of the charging box, and rotates the charging box to the side where the charging port of the electric vehicle is located, shortens the distance from the charging box to the charging interface, thereby reducing the required length of the charging gun cable, thus avoiding charging failures caused by cable tangling, and improving the service life of the charging gun cable and the power connection cable.

[0038] The charging device for electric vehicles according to the present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0039] In the description of this specification, terms such as "one embodiment" or "some embodiments" mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0040] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0041] Because multi-level parking garages contain multiple parking spaces, frequent lifting and lateral movement of vehicle pallets are required to meet parking and retrieval needs. Conventional long charging cables are very prone to entanglement with other charging cables in adjacent parking spaces or other equipment such as the frame of the multi-level parking garage. This can lead to damage or breakage of the charging cables during lifting and lateral movement of the vehicle pallets, ultimately causing charging failures.

[0042] Furthermore, while various vehicle charging solutions based on reels have been proposed in this field, which can release the corresponding length of the charging cable according to the distance to the charging port and promptly retract the cable after charging is completed to avoid entanglement with other charging cables or adjacent devices, and meet the needs of charging vehicles in multiple parking spaces, the diameter of the charging cable is constantly increasing with the continuous development of vehicle fast charging technology. Consequently, the corresponding maximum bending radius is also constantly increasing. This reel-based vehicle charging solution not only requires frequent bending of the charging cable, but also suffers from an excessively small bending radius in the central area. Therefore, it is highly susceptible to damage and breakage due to frequent and excessive bending, thus affecting the service life of the charging cable.

[0043] The following is a reference appendix. Figures 1 to 7 The present invention describes a charging device 100 for an electric vehicle.

[0044] According to an embodiment of the present invention, an electric vehicle charging device 100 is applied to a multi-level parking garage, the multi-level parking garage including a vehicle carrier tray 200. Please refer to [reference needed]. Figure 1 The charging device includes: a power supply 1, a charging box 2, a rotating support mechanism 3, a transverse drag chain 4, and a power connection cable 11. The charging box 2 is electrically connected to the power supply 1. The rotating support mechanism 3 includes a rotating shaft 31 and a rocker arm 32. The rotating shaft 31 is located at the edge of the vehicle carrier tray. One end of the rocker arm 32 is rotatably connected to the rotating shaft 31. The charging box 2 is supported on the other end of the rocker arm 32 and moves with the rocker arm 32 to a first height. The first height is determined based on the charging port height of at least one charging vehicle. The lateral drag chain 4 includes a first drag chain body 41 and a first support member 42. The first drag chain body 41 extends along the lateral movement direction of the vehicle pallet 200. One end of the first drag chain body 41 is fixed to the first support member 42, and the other end is fixed to the vehicle pallet 200. The power connection cable 11 passes through the lateral drag chain 4 to straighten the cable. One end of the power connection cable 11 is electrically connected to the power source 1, passes through the lateral drag chain 4, and is fixed to the rotating support mechanism 3. The other end of the power connection cable 11 is electrically connected to the charging box 2.

[0045] Specifically, the rotating support mechanism 3 can be located behind the parking position (i.e., Figure 1 (As shown in the Y direction), used to carry the idle charging box 2, and to rotate the charging box 2 to one side of the charging port of the electric vehicle (e.g., the left or right side of the vehicle) via the rotating support mechanism 3. Figure 1 (as shown in the X direction) to shorten the distance from the charging box 2 to the charging port of various types of electric vehicles, thereby reducing the required length of the charging gun cable 22.

[0046] The power connection cable 11 is connected to the power source 1 at one end and enters from one end of the first cable chain body 41 near the first support member 42, passes through the first cable chain body 41, and exits from the end of the first cable chain body 41 near the vehicle pallet 200. It is then fixedly connected to the rotating support mechanism 3 via the vehicle pallet 200 and electrically connected to the charging box 2 on the rotating support mechanism 3. In other words, by fixing the power connection cable 11 through the cable chain body to the rotating first support member 42, the position of the power connection cable 11 is fixed, avoiding cable tangling during use and improving the service life of the power connection cable 11.

[0047] In some embodiments, the first height may be comparable to the height of the charging port of an electric vehicle. Specifically, a technician may determine the first height based on the charging port height of at least one charging vehicle. For example, a technician may statistically analyze the charging port heights of various common charging vehicles on the market and determine the first height based on their maximum, minimum, or average values. Alternatively, for charging devices primarily serving a particular brand of vehicle, a technician may assign greater weighting coefficients to the charging port heights of several models of that brand and determine the first height through a weighted summation.

[0048] Thus, by rationally designing the first height at which the charging gun cable 22 detaches from the rotating support mechanism 3, this application can further shorten the distance from the idle charging gun 21 to the electric vehicle charging port in the height direction, thereby further reducing the required length of the charging gun cable 22 and further reducing the risk of the charging gun cable 22 becoming entangled.

[0049] Furthermore, the pivot 31 can be vertically mounted on the rear edge of the vehicle carrier 200 at the parking position to provide horizontal rotation. One end of the rocker arm 32 is connected to the pivot 31, and the charging box 2 is supported on the other end of the rocker arm 32. The rocker arm 32 rotates clockwise or counterclockwise around the pivot 31 in the horizontal direction to rotate and move the charging box 2 supported at one end of the rocker arm 32 to the side where the charging port of the electric vehicle is located.

[0050] In some embodiments, the first support member 42 may be a lateral limiting groove, and the first support member 42 is located along the lateral movement direction of the vehicle pallet 200 (e.g., Figure 1 Extending in the X direction (as shown), and the first support member 42 extends on at least one side (e.g.: Figure 1 A first strip-shaped opening extending along the lateral direction is provided on one side along the Y direction or one side along the Z direction (as shown). The bending radius of the first cable chain body 41 is greater than the limit bending radius of the power connection line 11, and one end of the first cable chain body 41 is fixed to the first position of the lateral limiting groove (e.g., as shown). Figure 1 (as shown on one side in the X direction), while the end of the first cable chain body 41 away from the first support member 42 is fixed to a second position on the vehicle pallet 200 (e.g., as shown on the other side in the X direction). Figure 1 The middle part of the Y-direction side shown) is inserted into the transverse limiting groove through the first strip opening as the vehicle pallet 200 moves laterally to the left, or is pulled out of the transverse limiting groove through the first strip opening as the vehicle pallet 200 moves laterally to the right.

[0051] One end of the power connection cable 11 is connected to the power source 1, while the other end of the power connection cable 11 extends into the first cable chain body 41 via the first position and extends out of the first cable chain body 41 from the second position, and is then fixedly connected to the rotating shaft 31 of the rotating support mechanism 3 via the vehicle pallet 200. In this way, the power connection cable 11, under the constraint of the lateral cable 4, can be embedded in the lateral limiting groove or pulled out of the lateral limiting groove as the vehicle pallet 200 moves laterally. This maintains charging of the electric vehicle during the lateral movement of the vehicle pallet 200, avoids entanglement with the power connection cables 11 of other charging spaces and / or equipment such as the garage frame, which could lead to cable damage or garage alarms, and avoids damage or breakage due to excessive bending.

[0052] It should be noted that the charging box 2 can be configured as an AC charging box 2 or a small DC charging box 2. The specific charging box 2 is configured according to the actual production needs and the load-bearing capacity of the rotating support mechanism 3, which will not be elaborated here.

[0053] According to the present invention, the charging device 100 for electric vehicles overcomes the above-mentioned defects of the prior art by fixing the power connection line 11 and rotating the charging box 2 to the side where the charging port of the electric vehicle is located, thereby shortening the distance from the charging box 2 to the charging interface, reducing the required length of the charging gun line 22, thereby avoiding charging failures caused by cable tangling, and improving the service life of the charging gun line 22 and the power connection line 11.

[0054] In some embodiments of this utility model, such as Figures 1 to 5 As shown, the rocker arm 32 rotates horizontally or vertically relative to the ground around the pivot 31. That is, the length of the pivot 31 can be greater than the height from the top of the electric vehicle to the ground, meaning the distance from the rocker arm 32 and the charging box 2 supported on the rocker arm 32 to the ground is greater than the height from the top of the electric vehicle to the ground. The end of the rocker arm 32 with the charging box 2 rotates horizontally around the pivot 31 to rotate and move the charging box 2 carried by the rocker arm 32 to the side where the charging port of the electric vehicle is located, thereby avoiding collisions with vehicles parked in the same or adjacent parking spaces during rotation. Furthermore, the charging gun 21 can detach from the charging box 2 at the first height, allowing the user to plug the charging gun 21 into the nearest charging port of the electric vehicle and plug it back into the nearest charging box 2 after charging is complete.

[0055] For example, when the charging port of the electric vehicle is on its left side, the user can manually rotate the rocker arm 32 horizontally to the left side of the vehicle before or after the vehicle enters the parking position, so as to plug the charging gun 21 into the charging port on the left side of the electric vehicle nearby, and after charging is completed, plug the charging gun 21 back into the charging box 2 at the end of the rocker arm 32 nearby.

[0056] For example, when the charging port of the electric vehicle is on its right side, the user can manually rotate the rocker arm 32 horizontally to the right side of the vehicle before or after the vehicle enters the parking position, so as to plug the charging gun 21 into the charging port on the right side of the electric vehicle nearby, and after charging is completed, plug the charging gun 21 back into the charging gun 21 box at the end of the rocker arm 32 nearby.

[0057] Thus, by reducing the distance from the charging box 2 to the charging interface in both the planar and vertical directions, the required length of the charging gun cable 22 is reduced, and this length is limited to less than the first height. This invention can further avoid charging failures caused by cable tangling and prevent the charging gun 21 and charging gun cable 22 from falling to the ground or the vehicle tray 200, thus avoiding the risk of electric shock. Furthermore, by using the rocker arm 32 to position and rotate the charging box 2 to a location inside the parking space near the charging port, the user can complete all charging operations for the vehicle on the spot without having to cross the vehicle tray 200, thus providing higher safety and convenience.

[0058] In some embodiments of this utility model, such as Figure 1As shown, the rotating support mechanism 3 also includes a first rod 33. The rotating shaft 31 is vertically installed behind the parking position. The rocker arm 32 rotates horizontally around the rotating shaft 31 to rotate and move the charging box 2 it carries to the side where the charging port of the electric vehicle is located. The first rod 33 is connected to one end of the rocker arm 32 away from the rotating shaft 31. The other end of the first rod 33 extends upward to the first height and is provided with the charging box 2.

[0059] Specifically, the pivot 31 can be vertically mounted on the rear edge of the vehicle carrier tray 200 at the parking position. The rocker arm 32 can rotate horizontally around the pivot 31 to rotate and move the charging box 2 it carries to the side where the charging port of the electric vehicle is located. The first end of the first rod 33 is connected to the end of the rocker arm 32 away from the pivot 31, and the second end of the first rod 33 extends upward to a first height (e.g., the height of the charging port). The length of the charging gun cable 22 of the charging box 2 is less than the first height, so that the user can plug the charging gun 21 of the charging box 2 at its end into the charging port of the electric vehicle nearby, and plug it back into the charging box 2 nearby after charging is completed.

[0060] For example, when the charging port of the electric vehicle is on its left side, the user can rotate the rocker arm 32 horizontally to the left side of the vehicle before the vehicle enters the parking position, so as to plug the charging gun 21 of the charging box 2 into the charging port on the left side of the electric vehicle nearby, and after charging is completed, plug it back into the charging box 2 at the end of the first rod 33 nearby.

[0061] For example, when the charging port of the electric vehicle is on its right side, the user can rotate the rocker arm 32 horizontally to the right side of the vehicle before the vehicle enters the parking position, so as to plug the charging gun 21 on the charging box 2 into the charging port on the right side of the electric vehicle nearby, and after charging is completed, plug it back into the charging box 2 at the end of the first rod 33 nearby.

[0062] In some embodiments of this utility model, such as Figure 2 As shown, the rotating support mechanism 3 also includes a second rod 34 and a crossbar 35. The second rod 34 is vertically installed behind the parking position. The rotating shaft 31 is horizontally installed at the first height of the second rod 34. The rocker arm 32 is used to rotate vertically around the rotating shaft 31 to rotate and move the charging box 2 it carries to the side where the charging port of the electric vehicle is located. The first end of the crossbar 35 is connected to the end of the rocker arm 32 away from the rotating shaft 31. The second end of the crossbar 35 extends to the charging port of the electric vehicle and is provided with the charging box 2.

[0063] Specifically, the second rod 34 can be vertically installed on the rear edge of the vehicle carrier tray 200 at the parking position. The pivot 31 is horizontally installed at the first height of the second rod 34. The rocker arm 32 can rotate vertically around the pivot 31 to rotate and move the charging box 2 it carries to the side where the charging port of the electric vehicle is located. The first end of the crossbar 35 is connected to the second end of the rocker arm 32, and the second end of the crossbar 35 extends forward to the charging port of the electric vehicle and is provided with an empty charging box 2 for carrying.

[0064] For example, when the charging port of the electric vehicle is on its left side, the user can vertically rotate the rocker arm 32 to the left side of the vehicle before or after the vehicle enters the parking position, so as to plug the charging gun 21 into the charging port on the left side of the electric vehicle nearby, and after charging is completed, plug the charging gun 21 back into the charging box 2 at the end of the crossbar 35 nearby.

[0065] For example, when the charging port of the electric vehicle is on its right side, the user can vertically rotate the rocker arm 32 to the right side of the vehicle before or after the vehicle enters the parking position, so as to plug the charging gun 21 into the charging port on the right side of the electric vehicle nearby, and after charging is completed, plug the charging gun 21 back into the charging box 2 at the end of the crossbar 35 nearby.

[0066] Thus, by reducing the length of the charging gun cable 22 in six directions—front, back, left, right, top, and bottom—and limiting this length to less than the first height, this invention can further avoid charging malfunctions caused by cable tangling and prevent the charging gun 21 and charging gun cable 22 from accidentally falling to the ground or the vehicle tray 200, thus avoiding the risk of electric shock. Furthermore, by using the rocker arm 32 to position and rotate the charging box 2 inside the parking space near the charging port, the user can complete all charging operations for the vehicle on the spot without having to cross the vehicle tray 200, thus providing higher safety and convenience.

[0067] In some embodiments of this utility model, such as Figures 1 to 5The AC charging box 2 shown also includes a charging cable 22 and a charging gun 21. One end of the charging cable 22 is connected to the AC charging box 2, and the other end is connected to the charging gun 21. The length of the charging cable 22 is less than the first height. Specifically, by reducing the distance from the charging box 2 to the charging interface in both the planar and vertical directions, the required length of the charging cable 22 is reduced, and this length is limited to less than the aforementioned first height. This application can further avoid charging failures caused by cable tangling and prevent the charging gun 21 and the charging cable 22 from accidentally falling to the ground or the vehicle carrier tray 200, thus avoiding the risk of electric shock. In addition, by using the rocker arm 32 to set and rotate the charging box 2 to a position inside the parking location near the charging port, the user can complete all operations for charging the vehicle on the spot without crossing the vehicle carrier tray 200, thus providing higher safety and convenience.

[0068] In addition, the charging box 2 can be positioned outward from the vehicle carrier tray 200, so that the insertion direction of the charging gun 21 in the charging box 2 is consistent with its insertion direction in the vehicle charging port, so that the user can observe the position of the charging box 2 and facilitate its quick location and use.

[0069] In some embodiments of this utility model, such as Figure 3 As shown, the charging device 100 for the electric vehicle also includes a first lifting drag chain 5. The vehicle pallet 200 includes a pallet body 201 and a pallet frame 202. The pallet body 201 can be embedded in the pallet frame 202. One end of the first drag chain body 41 is fixed to the first support member 42, and the other end and the first end of the first lifting drag chain 5 are both fixed to the pallet frame 202. The second end of the first lifting drag chain 5 is fixed to the pallet body 201.

[0070] Specifically, for devices that simultaneously possess lateral and vertical movement (such as...) Figure 3 The vehicle pallet 200 (shown in the Z direction) has a lateral movement function. The pallet frame 202 has a lateral movement function, and the pallet body 201 has both lifting and lateral movement functions. The pallet body 201 can descend to the lower parking position to allow vehicles to enter and exit the parking space, and can rise back to the upper parking position to embed itself in the pallet frame 202, and then move laterally together with the pallet frame 202.

[0071] The lateral limiting groove extends along the lateral movement direction of the vehicle pallet 200, and at least one side (e.g.) Figure 3The first strip-shaped opening (shown in the X or Y direction) extends along the lateral direction. The bending radius of the first cable chain body 41 is greater than the limit bending radius of the power connection line 11, and the first end of the first cable chain body 41 is fixed to the first position of the lateral limiting groove (e.g., as shown in the X or Y direction). Figure 3 (as shown on one side in the X direction), while the second end of the first cable chain body 41 is fixed to the second position of the pallet frame 202 (e.g., as shown on one side in the X direction), and the second end of the first cable chain body 41 is fixed to the second position of the pallet frame 202 (e.g., as shown on one side in the X direction). Figure 3 The middle part of the Y-direction side shown), and as the pallet frame 202 moves laterally to the left, it is inserted into the lateral limiting groove through the first strip opening, or as the pallet frame 202 moves laterally to the right, it is pulled out of the lateral limiting groove through the first strip opening. The bending radius of the lifting cable 5 is also greater than the limit bending radius of the power connection cable 11. The first end of the lifting cable 5 is also fixed to the second position of the pallet frame 202, and the second end of the lifting cable 5 is fixed to the third position of the pallet body 201 (e.g., as shown). Figure 3 (The middle part on one side in the Y direction shown), and unfolds as the tray body 201 moves downward longitudinally, or bends as the tray body 201 moves upward longitudinally.

[0072] The fixed section of the power connection cable 11 can be divided into two sections: a first fixed section and a second fixed section. One end of the first fixed section is electrically connected to the power source 1, while the other end of the first fixed section extends into the transverse cable chain 4 via the first position and extends out of the transverse cable chain 4 from the second position. One end of the second fixed section is electrically connected to the end of the first fixed section away from the power source 1, while the other end of the second section extends into the lifting cable chain 5 from the second position and extends out of the lifting cable chain 5 from the third position, and is then fixedly connected to the rotating shaft 31 of the rotating support mechanism 3 via the pallet body 201.

[0073] Thus, the first segment of the power connection cable 11, under the constraint of the lateral drag chain 4, can be embedded in or pulled out of the lateral limiting groove as the pallet frame 202 moves laterally. This maintains charging of the electric vehicle during the lateral movement of the vehicle pallet 200, preventing entanglement with power connection cables 11 of other charging spaces and / or equipment such as the garage frame, which could lead to cable damage or garage alarms, and also preventing damage or breakage due to excessive bending. The second segment of the power connection cable 11, under the constraint of the lifting drag chain 5, can unfold or bend appropriately as the vehicle pallet 200 moves longitudinally. This maintains charging of the electric vehicle during the longitudinal movement of the vehicle pallet 200, preventing entanglement with power connection cables 11 of other charging spaces and / or equipment such as the garage frame, which could lead to cable damage or garage alarms, and also preventing damage or breakage due to excessive bending.

[0074] In some embodiments of this utility model, such as Figure 4 , Figure 5 and Figure 6 As shown, the vehicle pallet 200 includes a pallet body 201, a pallet frame 202, a first conductive element 2011, and a second conductive element 2021. The first conductive element 2011 is mounted on the pallet body 201, and the second conductive element 2021 is mounted on the pallet frame 202 corresponding to the first conductive element 2011. That is, for the vehicle pallet 200 which simultaneously has lateral movement and lifting functions, the lifting cable chain 5 in the above embodiment can be replaced by a connecting mechanism. That is, the electric vehicle charging device 100 only needs to be configured with the first support member 42 and the lateral movement cable chain 4. The first support member 42 can be a lateral limiting groove. The pallet frame 202 in the vehicle pallet 200 only has a lateral movement function, and the second conductive element 2021 is located at its fifth position. The pallet body 201 has both lifting and lateral movement functions. The first conductive element 2011 is provided at the fourth position of the pallet body 201. It can descend to the lower parking position to allow vehicles to enter and exit the parking space, and rise back to the upper parking position to be embedded in the pallet frame 202, so as to realize the conduction between the first conductive element 2011 and the second conductive element 2021, and then move laterally together with the pallet frame 202.

[0075] Correspondingly, the first end of the first cable chain body 41 is fixed to the first position of the transverse limiting groove (e.g., as shown in the figure). Figure 4 (as shown on one side of the X direction), while the second end of the first cable chain body 41 is fixed to the second position of the pallet frame 202 (e.g., as shown on one side of the X direction), and the second end of the first cable chain body 41 is fixed to the second position of the pallet frame 202 (e.g., as shown on one side of the X direction). Figure 4The fourth segment (located in the middle of the Y-direction side) moves laterally with the tray frame 202. The power connection line 11 can consist of at least two independent cables and is divided into two segments (i.e., a first segment and a second segment). Here, the first end of the first segment is connected to the power source 1, while its second end extends into the first cable carrier body 41 via the first position and extends out of the first cable carrier body 41 from the second position, so as to be fixedly connected to the first conductive element 2011 via the tray frame 202. The first end of the second segment is fixedly connected to the second conductive element 2021, while the second end of the fourth segment is fixedly connected to the rotating shaft 31 of the rotating support mechanism 3 via a cable channel provided in the tray body 201.

[0076] In some embodiments of this utility model, the first conductive element 2011 and / or the second conductive element 2021 include a support structure (not shown), an elastic buffer structure (not shown), and a conductor (not shown). The support structure is disposed on the corresponding tray body 201 or tray frame 202. A first end of the elastic buffer structure is connected to the support structure, and a second end is connected to the conductor. Here, the first support structure is disposed at a fourth position on the tray body 201 to support the first elastic buffer structure (not shown). A first end of the first elastic buffer structure is connected to the first support structure (not shown), and a second end is connected to the first conductor (not shown), for fine-tuning the relative position of the first conductor to improve the docking success rate of the first conductive element 2011 and the second conductive element 2021, and deforms when the tray body 201 is embedded in the tray frame 202 to reduce the contact resistance between the first conductor and the second conductive element 2021.

[0077] Furthermore, in some embodiments, the second conductive element 2021 may include a second support structure (not shown), a second elastic buffer structure (not shown), and a second conductor (not shown). Here, the second support structure is disposed at a fifth position on the tray frame 202 to support the second elastic buffer structure. A first end of the second elastic buffer structure is connected to the second support structure, and a second end is connected to the second conductor, for fine-tuning the relative position of the second conductor to improve the success rate of docking between the second conductor and the first conductive element 2011, and deforming when the tray body 201 is embedded in the tray frame 202 to reduce the contact resistance between the second conductor and the first conductive element 2011.

[0078] Compared to Figure 3 The embodiment shown, Figure 4The docking mechanism used in the illustrated embodiment effectively avoids interference from the drooping lifting cable 5 with the lower parking position, making it more suitable for use in multi-level parking garages with three or more floors. Furthermore, since the first segment of the power connection cable 11 can still be embedded in or pulled out of the lateral limiting groove as the pallet frame 202 moves laterally, under the constraint of the lateral moving cable 4, this solution can still maintain charging of the electric vehicle during the lateral movement of the vehicle pallet 200. This avoids entanglement with the power connection cables 11 of other charging spaces and / or equipment such as the parking garage frame, which could lead to cable damage or parking garage alarms, and also avoids damage or breakage due to excessive bending.

[0079] In summary, the electric vehicle charging device 100 provided by this utility model can raise the initial height of the charging box 2 by fixing the power supply 1 and rotating the charging box 2 to the side where the charging port of the electric vehicle is located, thereby shortening the distance from the charging box 2 to the charging interface, reducing the required length of the charging gun cable 22, thus avoiding charging failures caused by cable tangling, and improving the service life of the charging gun cable 22 and the power connection cable 11.

[0080] According to an embodiment of the present invention, a charging device 100 for an electric vehicle is applied to a multi-level parking garage, the multi-level parking garage including a vehicle carrier tray 200, such as... Figure 7 As shown, the charging device 100 includes: a power supply 1, a charging box 2, a rotating support mechanism 3, a second lifting cable 6, and a power connection cable 11. The charging box 2 is electrically connected to the power supply 1. The rotating support mechanism 3 includes a rotating shaft 31 and a rocker arm 32. The rotating shaft 31 is located at the edge of the vehicle pallet 200. One end of the rocker arm 32 is rotatably connected to the rotating shaft 31. The charging box 2 is supported on the other end of the rocker arm 32 and moves with the rocker arm 32 to a first height. The second lifting cable 6 includes a second cable body 6 and a second support member (not shown). The second cable body 6 extends along the lifting direction of the vehicle pallet 200. One end of the second cable body 6 is fixed to the second support member, and the other end is fixed to the vehicle pallet 200. The power connection cable 11 passes through the second lifting cable 6 to straighten the cable. One end of the power connection cable 11 is electrically connected to the power supply 1, passes through the second lifting cable 6, and is fixed to the rotating support mechanism 3. The other end of the power connection cable 11 is electrically connected to the charging box 2.

[0081] Specifically, the second support member (not shown in the figure) can be configured as a longitudinal limiting groove (not shown in the figure), the second support member extends along the lifting direction of the vehicle pallet 200, and at least one side (e.g. Figure 7A second strip-shaped opening (not shown) extending along the lifting direction is provided on one side along the X direction or one side along the Y direction. The bending radius of the second lifting chain 6 is greater than the limit bending radius of the power connection line 11, and the first end of the second lifting chain 6 is fixed to the fifth position of the longitudinal limiting groove (e.g., Figure 7 (as shown on one side in the Z direction), while the second end of the second lifting cable 6 is fixed to the sixth position of the vehicle pallet 200 (as shown). Figure 7 (as shown in the middle of one side along the Y direction), and along the vehicle pallet 200. Figure 7 The longitudinal movement in the Z direction is shown, and it is embedded in the longitudinal limiting groove via the second strip opening, or moves along the vehicle pallet 200. Figure 7 The longitudinal movement in the Z direction is shown, and the longitudinal limiting groove is pulled out through the second strip opening.

[0082] The first end of the fixed section of the power connection cable 11 is connected to the power source 1, while its second end extends into the second lifting cable 6 via the fifth position and extends out of the second lifting cable 6 from the sixth position, and is then fixedly connected to the rotating shaft 31 of the rotating support mechanism 3 via the vehicle pallet 200. Thus, the fixed section of the power connection cable 11, under the constraint of the second lifting cable 6, can be embedded in the longitudinal limiting groove or pulled out of the longitudinal limiting groove as the vehicle pallet 200 moves longitudinally. This maintains charging of the electric vehicle during the longitudinal movement of the vehicle pallet 200, avoiding entanglement with charging cables of other charging spaces and / or equipment such as the garage frame, which could lead to cable damage or garage alarms, and preventing damage or breakage due to excessive bending.

[0083] Furthermore, in other embodiments, such as Figure 7 As shown, for the vehicle carrier pallet 200 that only has a lifting function, the charging device 100 may only include the second lifting cable chain 6, without the longitudinal limiting groove. In this case, the first end of the second lifting cable chain 6 can be fixed to the frame of the automated parking system and remain vertically hanging down under the constraint of gravity and the cable chain joint. Subsequently, the second lifting cable chain 6 can extend downward as the vehicle carrier pallet 200 descends, or bend upward as the vehicle carrier pallet 200 rises, thus avoiding entanglement with the power connection cable 11 of other charging spaces and / or the automated parking system frame, which could lead to cable damage or parking system alarms. It also avoids damage or breakage of the power connection cable 11 due to excessive bending.

Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
