Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective equipment technology, and more specifically, to a protective device for a charging adapter. Background Technology
[0002] Currently, with the development of electric vehicles, different countries and regions have set up different standard charging interfaces. These different standard charging interfaces cannot be used directly. Therefore, charging adapters are used to adapt the charging gun to the charging interface of the electric vehicle to convert the different current standards. However, electric vehicle charging is mostly done outdoors and involves repeated plugging and unplugging. Charging adapters are not provided with protective packaging during use, meaning users cannot guarantee that the appearance of the charging adapter will not be affected during the product trial period. This can easily lead to surface damage or wear. If users return the product during the trial period, it will affect the resale of the charging adapter, increasing the manufacturer's costs. Utility Model Content

The first clearance portion is configured to avoid the heat dissipation component of the charging adapter when it is installed in the receiving cavity. The second clearance portion is configured to avoid the locking component of the charging adapter when it is installed in the receiving cavity.
[0006] Furthermore, the housing includes a first end and a second end disposed opposite to each other. The first end is provided with a first opening, and the second end is provided with a second opening. The housing includes a first housing and a second housing integrally disposed thereon. The first opening is located in the first housing, and the second opening is located in the second housing. The first housing, the second housing, the first opening, and the second opening surround and form the receiving cavity. Along the direction away from the first housing, the cross-sectional area of the second housing gradually decreases.
[0007] Furthermore, the first clearance portion is disposed in the first housing, and the first clearance portion includes a plurality of first clearance openings, which are configured to clearance the heat dissipation components of the charging adapter when the charging adapter is installed in the receiving cavity.
[0008] Furthermore, the second clearance portion includes a locking switch clearance portion and a locking latch clearance portion, wherein the locking switch clearance portion is disposed in the first housing, and the locking latch clearance portion is disposed between the second housing and the second opening.
[0009] Furthermore, the locking switch avoidance part includes an avoidance protrusion protruding from the first housing, the avoidance protrusion being configured to avoid the locking switch of the charging adapter when the charging adapter is installed in the receiving cavity, and the locking latch avoidance part includes a second avoidance opening, the second avoidance opening being configured to avoid the locking latch of the charging adapter when the charging adapter is installed in the receiving cavity.
[0010] Furthermore, the housing is also provided with a third clearance portion, which is located in the second housing. The third clearance portion includes at least one concave arc surface, which is configured to clearance the charging interface when the charging adapter is installed in the receiving cavity and inserted into the corresponding charging interface.
[0011] Furthermore, a bending portion is provided on the side of the first housing near the first opening. The bending portion includes a first straight section and a second straight section.

[0027] See Figures 1 to 5As shown, according to an embodiment of this application, a protective device for a charging adapter is provided. In this embodiment, the outer surface of the charging adapter 20 is provided with a heat dissipation component 21 and a locking component 22. The heat dissipation component 21 includes one or more cooling fans, and the locking component 22 includes a locking switch 221 and a locking latch 222. The locking switch 221 can control the locking latch 222 to lock the charging adapter 20 when it is inserted into the charging interface. The protective device of this embodiment includes a housing 10. The housing 10 is provided with a mounting cutout 11, a first clearance portion 12, and a second clearance portion 13. The mounting cutout 11 is provided through the length direction of the housing 10 and has an open state and a closed state. A receiving cavity 14 is provided inside the housing 10. The charging adapter 20 is installed in the receiving cavity 14 through the mounting cutout 11. The first clearance portion 12 is configured to avoid the heat dissipation component 21 of the charging adapter 20 when the charging adapter 20 is installed in the receiving cavity 14. The second clearance portion 13 is configured to avoid the locking component 22 of the charging adapter 20 when the charging adapter 20 is installed in the receiving cavity 14.
[0028] In this embodiment, after the charging adapter 20 is installed into the receiving cavity 14 of the housing 10 through the installation cut 11, the installation cut 11 is switched from the open state to the closed state. The protective device can effectively enclose the charging adapter 20, and the housing 10 can prevent external factors from causing physical damage such as collisions and scratches to the surface of the charging adapter 20. Furthermore, by setting the first avoidance part 12 to avoid the heat dissipation component 21 of the charging adapter 20, and by setting the second avoidance part 13 to avoid the locking component 22 of the charging adapter 20, the surface of the charging adapter 20 can be protected without affecting its use. This can improve the user's product experience and, in the event of a customer's dissatisfaction and return, does not affect the resale of the charging adapter 20, thus improving the appearance integrity of the charging adapter 20. The first avoidance part 12 can avoid the heat dissipation component 21 of the charging adapter 20. When the charging adapter 20 generates heat and requires the cooling fan to operate for heat dissipation, the heat dissipation component 21 will not be blocked by the protective device and will not be unable to work normally, thus ensuring that its heat dissipation function is successfully realized. Meanwhile, this design avoids damage to the surface of components such as the cooling fan due to improper contact between the protection device and the heat dissipation component 21, ensuring that the surface of the heat dissipation component 21 remains in good condition during normal heat dissipation. This also indirectly ensures that the charging adapter 20 as a whole operates in a more stable environment due to good heat dissipation, reducing adverse effects on the surface and interior of the charging adapter 20 caused by overheating or other issues. By using the second clearance part 13 to avoid the locking component 22 of the charging adapter 20, the locking switch 221 and the locking buckle 222 are not interfered with by the protection device when the charging adapter 20 is inserted into the charging interface for locking operations, and can normally perform their locking functions, ensuring a stable connection of the charging adapter 20 during charging. The installation notch 11 extends along the length of the housing 10 and has an open and closed state, which facilitates the smooth insertion of the charging adapter 20 into the receiving cavity 14. During the installation process, the installation notch 11 reduces the possibility of damage to the surface of the charging adapter 20 due to factors such as inconvenience in operation when placing it into the protective device, so that the charging adapter 20 can be easily and safely inserted into the protective receiving cavity 14.
[0029] Furthermore, the housing 10 includes a first end and a second end disposed opposite to each other. The first end is provided with a first opening 15, and the second end is provided with a second opening 16. The housing includes a first housing 17 and a second housing 18 integrally disposed. The first opening 15 is located in the first housing 17, and the second opening 16 is located in the second housing 18. The first housing 17, the second housing 18, the first opening 15, and the second opening 16 surround and form a receiving cavity 14. Along the direction away from the first housing 17, the cross-sectional area of the second housing 18 (the cross-section of the second housing 18 parallel to the second opening 16) gradually decreases. Along the direction away from the first housing 17, the cross-sectional area of the second housing 18 gradually decreases. In real life, many charging adapters are basically shaped with one end being relatively thick and the other end gradually tapering. The tapered housing 10 makes the shape of the receiving cavity 14 more closely fit the outline of the charging adapter, which can better adapt to the shape of the charging adapter 20, reduce the excess space inside the receiving cavity 14, and make the charging adapter 20 more stable inside. This avoids the charging adapter 20 from shaking or colliding with the inner wall due to the excessive space inside the receiving cavity during carrying and moving, and further enhances the protection of the charging adapter 20.
[0030] Furthermore, a first clearance portion 12 is disposed on the first housing 17. The first clearance portion 12 includes a plurality of first clearance openings, which are configured to allow the heat dissipation assembly 21 of the charging adapter 20 to pass through when the charging adapter 20 is installed in the receiving cavity 14. By providing a plurality of first clearance openings for the first clearance portion 12, the cooling fan on the surface of the charging adapter 20 can be exposed relative to the housing 10, thereby preventing the heat dissipation effect of the charging adapter 20 from being affected after the protective device is installed.
[0031] Furthermore, the second clearance part 13 includes a locking switch clearance part 131 and a locking latch clearance part 132. The locking switch clearance part 131 is disposed in the first housing 17, and the locking latch clearance part 132 is disposed between the second housing 18 and the second opening 16. When the charging adapter 20 needs to be inserted into the charging interface, the locking latch clearance part 132 clears the locking latch 222 of the charging adapter 20, allowing the charging adapter 20 to smoothly engage in the charging interface, preventing the protection device from affecting the fit between the charging adapter 20 and the charging interface and thus affecting charging. When the charging adapter 20 needs to be removed from the charging interface, the locking switch clearance part 131 ensures that the protection device does not affect the locking latch pressing.
[0032] Furthermore, the locking switch avoidance part 131 includes an avoidance protrusion protruding from the first housing 17. The avoidance protrusion is configured to avoid the locking switch 221 of the charging adapter 20 when it is installed in the receiving cavity 14. The locking latch avoidance part 132 includes a second avoidance opening, which is configured to avoid the locking latch 222 of the charging adapter 20 when it is installed in the receiving cavity 14. The locking switch avoidance part 131 adopts an avoidance protrusion design protruding from the first housing 17, which can accurately match the position and shape of the locking switch 221. When the charging adapter 20 is installed in the receiving cavity 14, the avoidance protrusion can cleverly avoid the locking switch 221, leaving sufficient space for its movement. This ensures that when the user operates the locking switch 221, it will not be obstructed by the protective device housing, and the locking latch 222 can be easily controlled, ensuring that the connection or disconnection operation of the charging adapter 20 and the charging interface can be carried out smoothly, thereby ensuring the stability and safety of the charging process. The locking buckle avoidance part 132 is provided with a second avoidance opening for avoiding the locking buckle 222. During the process of installing the charging adapter 20 into the receiving cavity 14, the second avoidance opening can accurately avoid the locking buckle 222, without hindering its extension and locking actions when the charging adapter 20 is inserted into the charging interface, as well as its unlocking and retraction actions after charging is completed. This ensures that the locking buckle 222 can perform its locking function normally and maintain a stable connection between the charging adapter 20 and the charging interface.
[0033] Furthermore, the housing 10 is also provided with a third clearance portion 181, which is located in the second housing 18. The third clearance portion 181 includes at least one concave arc surface, which is configured to clearance the charging interface when the charging adapter 20 is installed in the receiving cavity 14 and inserted into the corresponding charging interface. Existing charging interfaces generally have non-standard charging ports. The charging adapter 20 already has a structure for clearance of the charging port to accommodate various charging interface models. In this embodiment, the concave arc surface of the third clearance portion fits snugly against the clearance structure on the charging adapter 20, thus achieving clearance of the charging port and preventing the charging adapter 20 from being unable to be inserted into the charging interface due to the installation of a protective device. This ensures that the charging adapter 20 can be smoothly inserted into the socket, guaranteeing a smooth charging process. Furthermore, the concave arc surface design also helps to achieve correct positioning and limit between the charging adapter 20 and the charging port of the charging interface, improving charging efficiency.
[0034] Furthermore, a bending portion 171 is provided on the side of the first housing 17 near the first opening 15. The bending portion 171 includes a first straight section 172 and a second straight section 173. The first straight section 172 is connected to the first housing 17 and extends into the first housing 17. One end of the second straight section 173 is connected to the first straight section 172, and the other end of the second straight section 173 extends away from the first straight section 172. Because the cross-sectional area of the second housing 18 decreases along the direction close to the second opening 16 and the second housing 18 is in contact with the charging adapter, the charging adapter will not slide out of the second opening 16. However, if no limiting structure is provided on the first opening 15, the charging adapter 20 may slide out of the first opening 15. Therefore, by connecting the first housing 17 to the first housing 17 via the bending portion 171 and extending the first straight section 172 towards the inside of the first housing 17, the displacement of the charging adapter 20 in the receiving cavity 14 along the direction from the second opening 16 to the first opening 15 can be limited, preventing the charging adapter 20 from sliding out of the second opening 16 and improving the safety of the protection device. By providing a second straight section 173 connected to the first straight section 172 and extending in a direction away from the first straight section 172, the structural strength of the housing 10 can be improved. Furthermore, by bending twice between the first straight section 172 and the second straight section 173, the risk of cracking or deformation of the first opening 15 due to stress concentration is reduced, improving the durability of the entire protection device.
[0035] Furthermore, the housing 10 is also provided with a mounting crease 19, which is located at the other end of the housing 10 opposite to the mounting cutout 11. The mounting crease 19 allows for better switching between the open and closed states of the mounting cutout 11, improving the efficiency of installing or removing the charging adapter 20, and preventing damage to the housing 10 when switching the state of the mounting cutout 11.
[0036] Furthermore, when the mounting cutout 11 is in the closed state, the mounting cutout 11 is glued with adhesive tape. Gluing the mounting cutout 11 with adhesive tape allows for easy gluing and disassembly, does not occupy the structure of the housing 10, and does not affect the insertion and removal of the charging adapter 20.
[0037] Furthermore, the housing 10 includes a blister film housing. The blister forming process is simple and efficient, quickly processing film material into the required housing shape, significantly shortening the production cycle, improving production efficiency, enabling large-scale production, and reducing production costs. Moreover, the blister film has good flexibility, allowing it to cushion external impacts to a certain extent. When the protective device is impacted, the blister film housing can absorb some energy through its own deformation, reducing damage to the internal charging adapter 20 and providing effective protection. In addition, the blister film housing is lightweight, not adding excessive extra weight to the charging adapter 20, making it convenient to carry and operate, and improving the user experience.
[0038] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
