[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] According to the first aspect of the present invention, Figure 1-Figure 7As shown, a replaceable dust cover is provided, which is arranged on the panel 2 of the charging / discharging gun or the charging stand and is used to cover the panel 2, the dust cover body 1 and the connecting device. Two locking holes 21 are provided on one side of the panel 2. A hinge part 11 is provided on one side of the dust cover body 1. The hinge part 11 is provided with a through mounting hole 111; the connecting device includes a short shaft 3, a telescopic member 5 and a long shaft 4 that are sequentially abutted against the mounting hole 111, and a first pin 3 is provided on each of the short shaft 3 and the long shaft 4. 1 and a second pin shaft 41, the first pin shaft 31 and the second pin shaft 41 are respectively plugged into the two locking holes 21 to hinge the dust cover to the panel 2, when an external force is applied to the first pin shaft 31 or the second pin shaft 41 in the direction of the telescopic member 5, the short shaft 3 or the long shaft 4 squeezes the telescopic member 5 and deforms it, thereby retracting the first pin shaft 31 or the second pin shaft 41 into the mounting hole 111, and the dust cover body 1 is disconnected from the panel 2.

[0037] With the rapid development of new energy vehicles, the charging guns or discharge guns or charging bases used in new energy vehicles will be equipped with a waterproof and dustproof dust cover on the panel 2. The dust covers currently used are affected by external conditions after being assembled at the factory at the end customer's site, causing the dust cover body 1 to fall off or be damaged under violent conditions, and cannot be disassembled and reinstalled or replaced with a new dust cover body 1, which affects the overall product protection.

[0038] The dust cover of the present invention adds a connecting device. The hinged portion 11 of the dust cover body 1 is provided with a through mounting hole 111. The connecting device includes a short shaft 3, a telescopic member 5 and a long shaft 4 that are sequentially abutted against the mounting hole 111. The first pin 31 on the short shaft 3 and the second pin 41 on the long shaft 4 are respectively plugged into the two locking holes 21 on the panel 2. When an external force is applied to the first pin 31 or the second pin 41 in the direction of the telescopic member 5, the short shaft 3 or the long shaft 4 squeezes the telescopic member 5 and deforms it, thereby retracting the first pin 31 or the second pin 41 into the mounting hole 111. The dust cover 1 is removed from the panel 2 and reinstalled, and the original dust cover 1 or the newly replaced dust cover 1 can be reconnected to the two locking holes 21 through the first pin 31 and the second pin 41, thereby solving the problem that the currently used dust covers are affected by external conditions at the end customer after factory assembly, causing the dust cover 1 to be damaged or fall off from the panel 2 under violent conditions and unable to be disassembled, reinstalled or replaced, thereby affecting the overall product protection.

[0039] In some embodiments, as Figure 2-Figure 3As shown, the short shaft 3 includes the first pin shaft 31 and the first stop portion 32 axially connected in sequence, and the diameter of the first stop portion 32 is larger than that of the first pin shaft 31; the long shaft 4 includes the second pin shaft 41 and the second stop portion 42 axially connected in sequence, and the diameter of the second stop portion 42 is larger than that of the second pin shaft 41.

[0040] The structure is designed so that the diameter of the first stop portion 32 is larger than that of the first pin shaft 31 and the diameter of the second stop portion 42 is larger than that of the second pin shaft 41 so that the first stop portion 32 and the second stop portion 42 abut against the two ends of the telescopic member 5 to prevent the telescopic member 5 from being axially strung onto the first pin shaft 31 or the second pin shaft 41, so that the short axis 3 or the long axis 4 can squeeze the telescopic member 5 through the first stop portion 32 or the second stop portion 42 and deform it.

[0041] In some embodiments, as Figure 3 As shown, the mounting hole 111 is a stepped hole, the first stop portion 32, the telescopic member 5 and the long shaft 4 are arranged at the end of the stepped hole with a larger diameter, and the first pin shaft 31 is arranged at the end of the stepped hole with a smaller diameter. The stepped surface of the stepped hole cooperates with the first stop portion 32 in axial blocking to prevent the short shaft 3 from falling out of the mounting hole 111.

[0042] This structural design can prevent the connecting device from falling off from the mounting hole 111, thereby ensuring that the dust cover 1 will not fall off from the panel 2, ensuring that the panel 2 is always sealed and protected by the dust cover 1, thereby ensuring electrical safety.

[0043] In some embodiments, as Figure 2 As shown, the connecting device further includes a torsion spring 6 , which includes a spring body and a first torsion arm 61 and a second torsion arm 62 connected to the spring body. The spring body is sleeved on the second pin 41 .

[0044] In some embodiments, as Figure 4 As shown, one of the first torsion arm 61 and the second torsion arm 62 abuts against the panel 2 , and the other abuts against the dust cover 1 .

[0045] The torsion spring 6 can drive the dust cover 1 to pivot relative to the panel 2 and switch between an open state and a closed state.

[0046] In some embodiments, as Figure 4 As shown, the spring body is arranged in the end with a larger diameter of the stepped hole, and a circumferentially extending clamping groove 112 is provided on the hinge part 11. The clamping groove 112 is connected to the mounting hole 111, and the first torsion arm 61 and the second torsion arm 62 extend from the clamping groove 112.

[0047] The snap-fit ​​groove 112 can connect the first torsion arm 61 and the second torsion arm 62 to the hinge part 11, and then indirectly fix the long shaft 4 in the end with a larger diameter of the stepped hole through the torsion spring 6, preventing the torsion spring 6 and the long shaft 4 from axially disengaging in the mounting hole 111.

[0048] In some embodiments, as Figure 1 and Figure 4 As shown, the hinge part 11 also has a mounting groove 113 extending from the outside of the hinge part 11 to the snap-fit ​​groove 112 . The mounting groove 113 is connected to the mounting hole 111 , and the first torsion arm 61 and the second torsion arm 62 enter the snap-fit ​​groove 112 from the mounting groove 113 .

[0049] The addition of the mounting groove 113 facilitates the installation of the torsion spring 6 and the long shaft 4 in the mounting hole 111 , and also facilitates the removal of the torsion spring 6 from the long shaft 4 via the mounting groove 113 .

[0050] In some embodiments, as Figure 3 As shown, the inner hole of the spring body and the second pin shaft 41 are clearance-fitted.

[0051] The inner hole of the spring body and the second pin shaft 41 are clearance-fitted. The clearance is designed to prevent the spring body from hindering the movement and rotation of the second pin shaft 41, and secondly, to prevent interference and friction with the second pin shaft 41 during the process of the torsion spring 6 driving the dust cover body 1 to pivot, which is conducive to pivoting, protects the structure of the spring body and the second pin shaft 41, and increases the overall service life of the connecting device.

[0052] In some embodiments, as Figure 5 As shown, the locking hole 21 is a through hole, and a tool is used to extend into the other side of the locking hole 21 and abut against the first pin 31 or the second pin 41 and apply external force; or Figure 6 As shown, an axial unlocking groove 22 is provided on the side wall of the locking hole 21 , and a tool is used to extend into the unlocking groove 22 and abut against the first pin shaft 31 or the second pin shaft 41 and apply external force.

[0053] The design of the through hole or unlocking slot 22 facilitates the removal of the dust cover 1 from the panel 2 by using a tool, making the removal more convenient and quick, thereby increasing the removal speed.

[0054] In some embodiments, as Figure 7As shown, an opening portion 12 is provided on the side of the dust cover body 1 opposite to the hinge portion 11, and a seating groove 23 corresponding to the opening portion 12 is provided on the panel 2. When the dust cover body 1 is in a closed state, the opening portion 12 is matched and engaged in the seating groove 23, and the seating groove 23 is provided with at least two supporting portions 24 that abut against the opening portion 12, and a gap 25 is provided between two adjacent supporting portions 24 for manually shifting the opening portion 12 to disengage the opening portion 12 from the engagement with the seating groove 23.

[0055] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
