[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] This utility model provides a detachable dust cover structure, such as Figures 1-7 As shown, the device includes a dust cover body 101 and a pull cord 102 fixedly connected to the dust cover body 101 at one end. The other end of the pull cord 102 is provided with a locking part that can be detachably connected to the charging gun or charging socket. The dust cover body 101 is used to cover the charging gun head of the charging gun or the charging interface of the charging socket. The housing 20 of the charging gun or charging socket has an insertion hole 201 for the locking part to pass through and enter its inner side. The locking part includes a base integrally formed with the pull cord 102 and a locking part provided with a locking part. The locking head 103 at the free end of the base has a guide mechanism on the inner side of the insertion hole 201 for guiding the locking head 103 into the inside of the charging gun or charging base, and a locking mechanism located on the rotation path of the locking head 103 for locking the locking head 103. After the locking head 103 enters the inside of the charging gun or charging base through the insertion hole 201, rotating the locking part can lock the locking head 103 into the locking mechanism to prevent the locking part from falling off the inside of the charging gun or charging base.

[0031] In the field of new energy vehicles, the connection ports of charging guns and charging sockets usually require dust protection, that is, a dust cover 10 that can be opened and closed needs to be installed. The existing dust cover 10 is fixedly connected to the housing 20 of the charging gun or charging socket by a pull rope 102 or is detachably connected. However, the dust cover 10 with the fixed connection method cannot be removed and replaced when damaged. The dust cover 10 with the traditional detachable connection method is connected to the housing 20 by the locking head 103 at the other end of the pull rope 102 through an interference fit or snap-fit, which is difficult to remove. As a result, the dust cover 10 is not easy to remove and replace, and the locking is not secure. It is easy to cause the locking head 103 to separate from the housing 20 unexpectedly, causing the dust cover 10 to fall off and fail to protect the connection port of the charging gun or charging socket.

[0032] The dust cover body 101 of this utility model has a pull rope 102 fixedly connected to it, and a locking head 103 is provided on it for detachable connection to the insertion hole 201 on the charging gun or charging base housing 20. The locking head 103 enters the insertion hole 201 under the guidance of the guide structure inside the insertion hole 201. Rotating the locking part can lock the locking head 103 into the locking mechanism inside the insertion hole 201, which can prevent the locking part from falling off the inside of the charging gun or charging base. Rotating the locking head 103 in the opposite direction can also disengage the locking head 103 from the insertion hole 201, and remove the dust cover 10 from the housing 20.

[0033] The dust cover 10 structure of this design is installed into the insertion hole 201 under the guidance of the guide structure, and then the locking head 103 is rotated to lock it onto the housing 20 through the locking structure. This not only realizes the quick installation, replacement and maintenance of the dust cover 10, but also ensures the secure locking of the dust cover 10. The structure is simple, the operation is convenient, and the assembly and replacement efficiency is improved.

[0034] In some embodiments, such as Figures 4-5 As shown, the locking head 103 is a long strip structure, and a slot 1031 is provided on the side wall of one end of the long strip structure. The locking mechanism includes a first locking mechanism that engages with the slot 1031. Rotating the locking part can cause the first locking mechanism to be embedded in the slot 1031 to prevent the locking part from falling off from the inside of the charging gun or charging base.

[0035] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, the guiding mechanism includes an arc-shaped portion 203 arranged along the direction of the insertion hole 201 and a guiding portion 204 located inside the arc-shaped portion 203. The other end of the elongated structure is formed with a snap-fit ​​portion that slides and engages with the guiding portion 204. After the locking head 103 is inserted into the inside of the charging gun or charging base, the snap-fit ​​portion separates from the guiding portion 204.

[0036] The locking part and the guide part 204 slide together. When the locking head 103 is inserted into the insertion hole 201, the guide part 204 guides the locking head 103 into the insertion hole 201, making the assembly simpler and more efficient.

[0037] In some embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the first locking mechanism includes a transition portion 205 integrally formed with the arc-shaped portion 203, and a limiting portion 2051 extending from one end of the transition portion 205 facing the locking head 103. Rotating the locking portion allows the limiting portion 2051 to be embedded in the slot 1031.

[0038] The limiting part 2051 is embedded in the card slot 1031 and engages with the card slot 1031 to limit the maximum depth to which the locking head 103 is inserted into the insertion hole 201.

[0039] In some embodiments, such as Figures 4-5 As shown, the guide portion 204 is a protruding rib 204 that protrudes from the inner wall of the arc-shaped portion 203, and the snap-fit ​​portion is a spring claw 1032 formed on the other end of the elongated structure and disposed opposite to it.

[0040] The relative shapes of the spring claw 1032 and the protruding rib 204 are matched, and the spring claw 1032 and the protruding rib 204 slide together. When the locking head 103 is inserted into the insertion hole 201, the spring claw 1032 and the protruding rib 204 can be matched and aligned before insertion. The protruding rib 204 plays a guiding role in the insertion of the locking head 103 into the insertion hole 201, making the assembly simpler and more efficient.

[0041] In some embodiments, such as Figures 6-7 As shown, the locking mechanism further includes a second locking mechanism 202 that engages with the other end of the elongated structure. When the first locking mechanism is embedded in the slot 1031, the second locking mechanism 202 engages with the other end of the elongated structure.

[0042] When the first locking mechanism is embedded in the slot 1031 and engaged with the slot 1031, the second locking mechanism 202 and the other end of the elongated structure are engaged to prevent the locking head 103 from rotating unexpectedly and causing the dust cover 10 to be unintentionally removed from the housing 20, thus preventing the dust cover 10 from protecting the charging gun head or the charging interface of the charging socket.

[0043] In some embodiments, such as Figures 6-7As shown, the second locking mechanism 202 includes a first barrier 2021 and a second barrier 2022 disposed on the inner edge of the insertion hole 201. The first barrier 2021 and the second barrier 2022 are vertically disposed between each other, and the first barrier 2021, the second barrier 2022 and the guide mechanism together limit the insertion of the locking head 103.

[0044] The first retaining wall 2021, the second retaining wall 2022, and the guiding mechanism together limit the insertion of the locking head 103, guide the locking head 103 to be inserted into the insertion hole 201 in the correct direction, play a guiding and error-proof role, improve assembly efficiency, and avoid unexpected damage to the insertion hole 201 and the housing 20 due to incorrect installation direction.

[0045] In some embodiments, such as Figure 7 As shown, the first barrier 2021 is disposed opposite to the guide mechanism, and the second barrier 2022 forms a receiving area between the guide mechanism to receive the rotating locking head 103; after the rotating locking head 103 separates from the guide mechanism, it falls into the receiving area to prevent the locking head 103 from rotating unexpectedly.

[0046] The second barrier 2022 and the guide mechanism are respectively blocked at both ends of the locking head 103 to prevent the dust cover 10 from being accidentally removed from the housing 20 due to the unexpected rotation of the locking head 103, which would prevent the dust cover 10 from protecting the charging interface of the charging gun head or charging socket.

[0047] In some embodiments, such as Figures 6-7 As shown, the rotation angle of the locking part is 90°.

[0048] The rotation angle is set to 90°, which facilitates the structural design of the guide structure, locking structure and locking head 103. This angle setting also makes it easier for the operator to assemble the locking head 103. Without using additional tools to measure the angle, the operator can correctly assemble and lock the locking head 103 onto the housing 20.

[0049] In some embodiments, such as Figure 5 As shown, the base includes a first base 104 that matches the shape of the insertion hole 201 and a second base 105 located between the first base 104 and the pull cord 102. The second base 105 has a support surface 1051 that matches the shape of the housing 20 of the charging gun or charging base.

[0050] The design of the support surface 1051 not only limits the maximum depth of the connector inserted into the plug hole 201, but also makes the support surface 1051 match the shape of the housing 20 of the charging gun or charging base, which also contributes to the aesthetic appearance.

[0051] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can 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.
