Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a direct plug-in type protective device for a charging seat. Background Art

[0002] In order to achieve a certain level of sealing during use, the charging interface of new energy vehicles needs to be equipped with a protective device. There are two common forms of protective devices at the port of the charging seat, one is a direct plug-in form, and the other is a spring cover form. When the direct plug-in form of the protective device protects the charging seat, it is pressed into the charging seat and prevented from falling out by squeezing. When the charging seat needs to be used for charging, the protective device is pulled out by external force. When the dustproof device in the form of a spring cover protects the charging seat, the protective device is pressed tightly by one end of the spring cover. When the charging seat needs to be used, the pressing end of the spring cover is opened.

[0003] Most existing plug-in protection devices use a hand grip structure as a force point for pulling out the dust cover. However, since the hand grip occupies a large volume, when the design space of the charging seat is limited, the large hand grip will cause great trouble to the design of the vehicle charging seat. Secondly, the dust cover and the charging seat of the existing protection device are mostly matched with an annular protrusion structure set in the cylindrical surface. In actual use, only this matching method will cause the plug-in and pull-out force of the dust cover to be too small, or the installation will not be tight. Moreover, the dust cover rope and the dust cover are mostly integrated, which is not conducive to disassembly and replacement. Summary of the invention

[0004] The utility model aims to provide a plug-in protection device for a charging stand, which can pull out a dust cover by setting a pull ring, thereby solving the problem that the hand-held part of the existing dust cover products occupies a large volume.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a direct plug-in protection device for a charging seat, including a dust cover adapted to the charging seat, and the dust cover is provided with at least one pull ring for pulling the dust cover.

[0006] Beneficial effects of this solution: This solution realizes pulling the dust cover by setting a pull ring on the dust cover. Compared with the hand-held structure, it greatly saves space, avoids charging troubles caused by insufficient space, and greatly reduces costs. This solution can be adapted to various types of dust covers by setting one or more pull rings, with uniform force and easy pulling of the dust cover.

[0007] As a preferred solution of the utility model, the pull ring is made of a deformable material, and the pull ring is connected to the upper surface of the dust cover by means of integral injection molding.

[0008] The beneficial effects of this solution: the material of the pull ring of this solution is a deformable material, and the pull ring can be reset when it is not under force, and it occupies a small space.

[0009] As a preferred solution of the utility model, the pull ring is made of a non-deformable material, and the pull ring is hingedly connected to the dust cover.

[0010] The beneficial effects of this solution: the material of the pull ring in this solution is a non-deformable material, the pull ring is hingedly connected to the dust cover, and the pull ring can be rotated and restored when no force is applied, and occupies little space.

[0011] As a preferred solution of the utility model, the dust cover is also detachably provided with a drawstring, and the other end of the drawstring is detachably connected to the charging base.

[0012] The beneficial effect of this solution is that the connection between the drawstring, the dust cover and the charging stand is detachable, which greatly facilitates disassembly and replacement.

[0013] As a preferred solution of the utility model, the dust cover is provided with a mounting hole for facilitating the pull rope to pass through and connect with the dust cover, and the pull rope is provided with a deformable protrusion at the connection with the mounting hole.

[0014] Beneficial effects of this solution: This solution is convenient for the pull rope to pass through the installation hole connected to the dust cover, which facilitates the detachable connection between the pull rope and the dust cover. This solution provides a deformable protrusion at the connection between the pull rope and the installation hole, which further facilitates the detachable connection between the pull rope and the dust cover and flexible disassembly.

[0015] As a preferred solution of the utility model, the upper surface of the dust cover is provided with a groove which is matched with the size of the pull ring and is used to accommodate the pull ring.

[0016] Beneficial effects of this solution: This solution further saves the space occupied by the pull ring by arranging a groove for the pull ring on its upper surface.

[0017] As a preferred solution of the utility model, a plurality of sealing members are evenly arranged on the side surface of the dust cover along the axial direction thereof.

[0018] The beneficial effects of this solution are as follows: In this solution, a plurality of seals are evenly arranged on the side of the dust cover along its axial vertical direction. When the dust cover is inserted, the seal can contact the charging seat, causing it to be stressed, thereby increasing the plug-in and pull-out force. By pressing down, the radial maximum outer contour of the dust cover is maximized on the square disk surface, thereby ensuring that the dust cover is firmly used.

[0019] As a preferred solution of the utility model, the sealing member is a rib structure.

[0020] As a preferred solution of the utility model, the sealing member is a ramp-type width-changing structure.

[0021] As a preferred solution of the present utility model, the sealing member is a curved surface structure. BRIEF DESCRIPTION OF THE DRAWINGS
