Description

Technical Field

[0001] The utility model relates to the technical field of charging guns, in particular to a dustproof structure for charging guns which is easy to store. Background Art

[0002] With the rapid development of new energy electric vehicle technology, the demand for charging is also increasing. As a connection device between electric vehicles and charging piles, charging guns are important components for realizing the interconnection between charging piles and electric vehicles. When not charging, the internal terminals of the charging gun head are exposed, which is easy to get wet and affect the normal operation of the internal electronic components. Therefore, a dust cover is often installed on the outside of the charging gun head for protection.

[0003] At present, traditional charging guns mostly use mechanical locking structures. Conventional dust covers are only installed on the outside of the charging gun head and cannot protect the locking hook. The locking hook is exposed on the upper part of the dust cover, which is easy to get wet and easily damaged by bumps. In addition, the existing dust covers are mostly fixedly connected to the tail of the charging gun by a connecting rope. The dust covers cannot be removed and replaced. Each model of charging gun needs to be equipped with a different dust cover. When charging, the dust cover is removed from the charging gun head and only the connecting rope is used to pull the dust cover to prevent it from being lost. During the operation of the charging gun, the dust cover is easy to shake with the connecting rope and is easy to be damaged by bumps with the charging gun or other objects. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a dustproof structure for a charging gun that is easy to store. The structure is simple, easy to store, and convenient to disassemble. It is suitable for charging guns of different models and can provide good protection for the charging gun head and the locking hook. The utility model can effectively solve the technical problems that the existing dust cover of the charging gun has poor protection effect and cannot be fixed and stored after being removed from the charging gun head, and is easily damaged by bumps.

[0005] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:

[0006] In one technical solution of the utility model, a dustproof structure for a charging gun that is easy to store is provided, including a dustproof end cover, the dustproof end cover is connected to the outer gun shell of the charging gun through a drawstring, and the dustproof end cover is sleeved on the outside of the charging gun head at the front end of the charging gun;

[0007] The external fixing sleeve of the outer gun housing is provided with an arc-shaped clamp, a T-shaped slide groove is opened on the outer arc surface of the clamp, a hollow slideway is opened inside the clamp, and the position of the slideway corresponds to the slide groove. A stop slider is fixed on the top of the dustproof end cover, and the dustproof end cover is clamped on the slideway through the stop slider and slides along the slide groove to movably connect the clamp.

[0008] By adopting the above technical solution, after removing the dustproof end cover from the charging gun head, the dustproof end cover can be connected by a pull rope to prevent it from falling off and being lost, and the dustproof end cover can also be removed and hung and stored under the clamp to avoid the dustproof end cover shaking and bumping when the charging gun is only pulled by the pull rope during charging.

When the open end is sleeved on the outside of the charging gun head, the limiting sleeve and the terminal mounting hole inside the charging gun head are engaged with each other to achieve rapid positioning, and at the same time, relative rotation between the dustproof end cover and the charging gun head can be limited to improve the stability of the connection.

[0010] Furthermore, a hook protection shell is provided on the top of the dustproof end cover, and a receiving cavity communicated with the outside is provided inside the hook protection shell, and a locking hook extending out of the outer gun shell is provided on the charging gun, and when the dustproof end cover is sleeved on the charging gun head, the locking hook extends into the receiving cavity. The hook protection shell is provided to cover and protect the locking hook to prevent it from being scratched and damaged, thereby preventing the stability of the charging gun from being locked when it is plugged into the charging seat.

[0011] Furthermore, the stopper slide includes a stopper and a connecting part, the connecting part is respectively connected to the stopper and the hook protection shell, when the dustproof end cover is connected to the clamp, the stopper is located in the slideway, and the connecting part is inserted into the slideway. The stopper is embedded in the slideway to form a limit position, and the dustproof end cover is suspended below the clamp.

[0012] Furthermore, the T-shaped slide groove includes a first notch and a second notch, the width of the first notch is greater than the width of the second notch, the width of the stopper is between the widths of the first notch and the second notch, and the width of the connecting portion is not greater than the width of the second notch. When in use, the stopper is first clamped in the first notch and slid along the direction of the second notch so that the stopper penetrates into the slideway, and at the same time, the connecting portion is placed in the second notch and slid along it to the end of the second notch, thereby connecting the dust cover to the clamp.

[0013] Furthermore, the cross section of the inner cavity of the opening end is a non-circular cross section, which matches the non-circular cross section of the charging gun head.

[0014] Furthermore, an annular groove is provided on the inner wall of the opening end, and a sealing rubber ring is embedded in the annular groove. When the dustproof end cover is mounted on the outside of the charging gun head, the sealing rubber ring is used to improve the sealing of the connection between the opening end and the charging gun head for waterproofing and moisture-proofing.

[0015] Furthermore, an extension plate is provided on the lower side of the open end, a through plug hole is opened in the extension plate, and a connecting column is provided on the outer gun housing; a limit plug and a limit ring are respectively provided at both ends of the pull rope, the limit plug is clamped in the plug hole, and the limit ring is sleeved on the connecting column, so as to realize the detachable connection between the dustproof end cover and the outer gun housing through the pull rope.
