Description

Technical Field

[0001] The utility model relates to the technical field of charging guns, in particular to a manual unlocking structure of a charging gun. Background Art

[0002] With the popularity of electric vehicles, the safety, usability and stability of charging guns, as key equipment for charging electric vehicles, have become the focus of the industry. The manual unlocking structure of the charging gun is an important part of the charging process, and its design directly affects the user experience and the overall performance of the charging gun.

[0003] Currently, many charging guns are equipped with manual unlocking devices. The manual unlocking device generally uses a wire rope to pull the unlocking rod, and uses the unlocking rod for manual unlocking. However, in actual use, the wire rope often breaks, causing the unlocking rod to be lost and unable to be manually unlocked. Utility Model Content

[0004] The purpose of the utility model is to provide a manual unlocking structure of a charging gun to solve the problems mentioned in the above background technology.

[0005] The technical solution of the utility model is a manual unlocking structure of a charging gun, comprising a charging gun body and a charging gun head, the charging gun head being mounted on the charging gun body, the charging gun body being mounted with a mechanical lock and a manual unlocking mechanism, the interior of the charging gun body being mounted with a reduction motor shaft, the reduction motor shaft being movably connected with a locking block, a mechanical lock head being mounted at a position of the bottom of the mechanical lock close to a gripping portion of the charging gun body, the mechanical lock head being arranged inside the charging gun body, the mechanical lock head being clamped with the locking block, a rod pulling movable hole being provided on the charging gun body, the rod pulling movable hole being communicated with the interior of the charging gun body, and the manual unlocking mechanism being mounted inside the rod pulling movable hole.

[0006] In one embodiment, the manual unlocking mechanism includes an unlocking rod and an unlocking rod fixing block, the unlocking rod is installed on the unlocking rod fixing block, the unlocking rod fixing block is installed in the rod movable hole, one end of the unlocking rod passes through the interior of the charging gun body, and the other end of the unlocking rod passes through the outside of the charging gun body, a rod spring is installed on the lower side of the unlocking rod, and one end of the rod spring is fixedly connected to the bottom of the rod movable hole.

[0007] In one embodiment, the mechanical lock is hinged inside the charging gun body and close to the top, and the top of the mechanical lock passes through to the outside of the top of the charging gun body.

[0008] The beneficial effects provided by the utility model are:

[0009] When manual unlocking is required, just press the unlocking lever to complete the manual unlocking. After the unlocking is completed, the unlocking lever can be reset by the elastic force of the lever spring. Since the unlocking lever is installed on the lever fixing block, and the lever fixing block is installed in the lever movable hole, the unlocking lever can always remain connected to the charging gun body and not be disconnected, thereby avoiding the problem of being unable to manually unlock due to the loss of the unlocking lever.

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The technical solution of the present invention will be further described below in conjunction with the drawings of the embodiments of the present invention, and the present invention is not limited to the following specific implementation methods.

[0016] It should be understood that the same or similar numbers in the drawings of the embodiments correspond to the same or similar parts. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom" and the like indicating the orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0017] In one embodiment, Figure 1-4As shown, a manual unlocking structure of a charging gun comprises a charging gun body 2 and a charging gun head 1, the charging gun head 1 is mounted on the charging gun body 2, a mechanical lock 3 and a manual unlocking mechanism 8 are mounted on the charging gun body 2, a reduction motor shaft 9 is mounted inside the charging gun body 2, a locking block 10 is movably connected to the reduction motor shaft 9, a mechanical lock head 11 is mounted at the bottom of the mechanical lock 3 near the gripping portion of the charging gun body 2, the mechanical lock head 11 is arranged inside the charging gun body 2, the mechanical lock head 11 is clamped with the locking block 10, a rod pulling movable hole 4 is opened on the charging gun body 2, the rod pulling movable hole 4 is communicated with the inside of the charging gun body 2, and the manual unlocking mechanism 8 is mounted inside the rod pulling movable hole 4.

[0018] In order to facilitate the release of the locking block 10, the manual unlocking mechanism 8 includes an unlocking rod 5 and an unlocking rod fixing block 6. The unlocking rod 5 is installed on the unlocking rod fixing block 6, and the unlocking rod fixing block 6 is installed in the rod movable hole 4. One end of the unlocking rod 5 passes through the interior of the charging gun body 2, and the other end of the unlocking rod 5 passes through the outside of the charging gun body 2. A rod spring 7 is installed on the lower side of the unlocking rod 5, and one end of the rod spring 7 is fixedly connected to the bottom of the rod movable hole 4.
