Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Chinese Patent Application No. 2024219624970, filed with the State Intellectual Property Office of China on August 13, 2024, the entire disclosure of which is incorporated herein by reference.

[0002] SUMMARY OF THE INVENTION Embodiments of the present disclosure generally relate to a charging dock back cover. [Background technology]

[0003] There are two main methods for fastening the rear cover of a DC charging dock under existing national standards. One main method is to use screws to fasten the rear cover, i.e., to fasten the charging dock rear cover to the charging dock housing via screws. The other main method is to use a fastening buckle for fastening. In this case, there are multiple fastening buckles on the charging dock housing, and a corresponding number of slots are arranged in corresponding positions on the charging dock rear cover. The fastening buckles on the charging dock housing are press-fitted into the slots in the charging dock rear cover, thereby securely attaching the charging dock rear cover to the charging dock housing.

[0004] Because both of the above major methods require a fixed fit between the charging dock rear cover and the charging dock housing, once the installation of the charging dock rear cover is completed via these two major methods, the charging dock rear cover is firmly connected to the charging dock housing, regardless of whether the charging dock rear cover is fixed using screws or by press-fitting the fixing buckle. Both the screws and the fixing buckle are immovable and cannot be easily and quickly removed manually, and may require the assistance of a specific tool for removal.

[0005] In addition, due to the characteristics that the reliability of the connection between the charging dock rear cover and the charging dock housing decreases when the connection is disassembled and reassembled using the above two fastening methods, the charging dock rear cover and the charging dock housing cannot be attached together and shipped to customers, so customers must purchase the rear cover separately as an accessory.

[0027] 1 to 6 , the present disclosure discloses a charging dock back cover 2 connected to a charging dock housing 1 via a movable hook 25. The charging dock back cover 2 includes a cover plate 21 and a side plate 22 extending vertically from the cover plate 21. The cover plate 21 is provided with a connection portion 23 that protrudes from the cover plate 21 toward the charging dock housing 1, and a through-hole 24 adjacent to the connection portion 23 is disposed so as to open in the cover plate 21. The movable hook 25 is configured to have an exposed pressing portion 251 and a hook portion 252 that is located within the cover plate 21 and extends beyond the connection portion 23. The movable hook 25 is configured to pass through the through-hole 24 and is connected to the side surface of the connection portion 23 via a support leg portion 253, allowing the movable hook 25 to swing around the support leg portion 253. The charging dock housing 1 is provided with a slot 11 that is adapted to the hook portion 252. When the charging dock rear cover 2 is fitted to the charging dock housing 1, the hook portion 252 is engaged with the slot 11, and by pressing the pressing portion 251, the hook portion 252 can be swung around the support leg portion 253 and removed from the slot 11.

[0028] The charging dock rear cover provided by the present disclosure can be attached by holding the charging dock rear cover 2 and pushing the hook portion 252 of the movable hook 25 into the slot 11 of the charging dock housing 1 via the pressing portion 251 of the movable hook 25. By simply pressing the pressing portion 251 of the movable hook 25, the hook portion 252 of the movable hook 25 can be swung around the support leg 253 to disengage from the slot 11 of the charging dock housing 1, and the charging dock rear cover can then be removed. Compared to existing charging dock rear covers that use screws or fastening buckles for fastening, the charging dock rear cover with the movable hook of the present disclosure saves parts, simplifies installation and removal, shortens assembly time, and can be quickly removed with one hand without requiring space for a screw locking tool, thereby miniaturizing the structure of the charging dock rear cover and saving space for manual operation. Additionally, because the charging dock back cover of the present disclosure can be easily and quickly removed from the charging dock housing, the charging dock back cover can be attached to the charging dock housing and shipped together to the customer, eliminating the need for the customer to purchase the back cover separately.

[0029] 1 to 4, the number of through-holes 24 and the number of movable hooks 25 are both two to ensure a more reliable and convenient connection between the charging dock back cover 2 and the charging dock housing 1 during user operation. The connection portion 23 is disposed between the two through-holes 24, and the two movable hooks 25 are connected to two opposite side surfaces of the connection portion 23 via the support legs 253 of the two movable hooks 25, respectively. In this way, the user can quickly remove the charging dock back cover 2 with one hand using the thumb and index finger.

[0030] 3 and 4, the two movable hooks 25 are arranged on two opposite side surfaces of the connection part 23. Furthermore, the connection part 23 itself has a symmetrical structure, with the two through holes 24 and the two movable hooks 25 being arranged symmetrically with respect to the center line of the connection part 23. By arranging the through holes 24 and the movable hooks 25 symmetrically with respect to the center of the connection part 23, it is possible to reduce the complexity of the structure, simplify the process, and reduce costs.

[0031] 3, the cover plate 2 is provided with a rectangular opening hole 26 that protrudes from the cover plate 2 toward the charging dock housing 1 between the two through holes 24. The side walls of the rectangular opening hole 26 surround a connection portion that is open at the top, and the movable hooks 25 are connected to two side walls on opposite sides of the connection portion via the support legs 253 of each movable hook 25. Naturally, the structure of the connection portion is not limited to this form as long as positions for attaching the movable hooks 25 can be provided on two side surfaces on opposite sides of the connection portion.

[0032] Furthermore, in the embodiment shown in FIGS. 1 to 4 , each of the through-holes 24 is a rectangular hole, and the cover plate 2 is provided with an operating unit 27. The operating unit 27 is a second hollow rectangular body formed by extending from three sides of each of the through-holes 24 toward the charging dock housing 1 so as not to extend beyond the hook portion 25. The top surface and the side surface of the second hollow rectangular body that is closer to the movable hook 25 are open, and the width of the second hollow rectangular body is smaller than the width of the through-hole 24, so that the pressing portion 251 of the movable hook 25 can be operated in the space surrounded by the second hollow rectangular body. By providing the operating unit 27, the opening area of ​​the through-hole 24 is reduced, preventing external dust and other foreign matter from entering the charging dock housing 1 and protecting the charging dock housing 1.

[0033] In order to increase the compactness of the structure of the charging dock back cover 2, each of the outer surfaces of the two side walls on opposite sides of the connection part is aligned with one side of each of the two through holes 24, so that the distance between the rectangular opening hole 26 and the through hole 24 is equal to the thickness of each of the side walls of the connection part.

[0034] In the embodiment shown in FIG. 3, the cross-sectional area of ​​the second hollow rectangular body is larger than the cross-sectional area of ​​the connection portion.

[0035] In one embodiment, the end face of the movable hook 25 away from the hook portion 252 is flush with the outer surface of the cover plate 21. By positioning the structure of the movable hook 25 so that it does not protrude beyond the cover plate 21, the end of the movable hook 25 is prevented from being damaged by collisions, thereby protecting the movable hook 25.

[0036] In one embodiment, the slots 11 are elongated through-holes disposed in the reinforcing ribs of the charging dock housing 1. In the embodiment shown in Figure 6, the slots 11 are two parallel elongated through-holes.

[0037] In one embodiment, the support legs 253 are elastic and perpendicular to the surface of the connection portion 23. Arranging the support legs 253 as elastic structures can prevent the support legs 253 from breaking after multiple uses.

[0038] According to an embodiment disclosed herein, as shown in FIG. 1 , a charging dock 3 is provided, which includes a charging dock housing 1 and a charging dock back cover 2 according to any of the above embodiments, wherein the charging dock back cover 2 is connected to the charging dock housing 1 via a movable hook 25.
