[0027] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, rather than all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application, its application, or use. Example 1

[0028] like Figures 1 to 6 As shown, this embodiment provides a mechanical locking structure for a charging interface, which includes a first mounting surface and a second mounting surface, the first mounting surface and the second mounting surface are in movable contact, a first snap-fit ​​structure and a second snap-fit ​​structure are provided on the first mounting surface and the second mounting surface, the first mounting surface and the second mounting surface are squeezed and snapped together under force, the first snap-fit ​​structure is used to position the movable contact point between the first mounting surface and the second mounting surface, and the second snap-fit ​​structure is used to limit the movement range of one end of the first mounting surface; wherein a reset member 300 is connected between the first mounting surface and the second mounting surface, one side of the first mounting surface is subjected to force, the first mounting surface moves around the movable contact point, the first mounting surface loses force, and the reset member 300 resets the first mounting surface.

[0029] When in use, the first mounting surface and the second mounting surface are arranged opposite to each other, and after being squeezed by force, they are formed into a whole under the action of the first buckling structure and the second buckling structure; the first mounting surface is pressed by force, and its other end is tilted. In the actual application structure, the corresponding parts will be installed. After the external force is withdrawn, the first mounting surface is reset under the deformation drive of the reset member 300.

[0030] The structure will be described in detail below with reference to the accompanying drawings.

[0031] As attached Figures 1 to 3 As shown, in this embodiment, the first mounting surface is the mechanical lock hook 100, and the second mounting surface is the charging gun housing 400. The mechanical lock hook 100 can be movable after installation, which is achieved by the cooperation of the rotating shaft 101 and the semicircular groove 403. The rotating shaft 101 is fixed on one side of the mechanical lock hook 100, and the semicircular groove 403 is fixed on the charging gun housing 400. After the mechanical lock hook 100 and the charging gun housing 400 are installed under pressure, the first buckling structure is force-fastened, and the second buckling structure is force-fastened. The rotating shaft 101 can move (rotate) in the semicircular groove 403. The range of movement is affected by the size of the groove surface of the semicircular groove 403. Usually, two semicircular grooves 403 are provided, and the two semicircular grooves 403 are fixed on the charging gun housing 400 in parallel and at intervals.

[0032] In some other embodiments, rotating holes are relatively arranged on the inner wall of the cavity of the charging gun housing 400, and a rotating shaft is arranged between the two rotating holes. This design requires the rotating shaft to be pre-installed, and the structural design is relatively complex, and the assembly process is more complicated than that of the embodiment.

[0033] As attached Figures 4 and 5 In this embodiment, the first locking structure includes two first locking portions 401. Beveled surfaces are provided at both ends of the rotating shaft 101. In this embodiment, the rotating shaft 101 can serve as part of the first locking structure. The first locking portion 401 is a protruding block with a beveled surface that matches the beveled surface on the rotating shaft 101. In actual production, both the mechanical locking hook 100 and the charging gun housing 400 are made of a tough material, such as plastic. When the mechanical locking hook 100 and the charging gun housing 400 are installed, the rotating shaft 101 is squeezed through the first locking portion 401 until the two are misaligned. The first locking portion 401 covers the rotating shaft 101 from below, and a portion of the rotating shaft 101 is now positioned within the semicircular groove 403.

[0034] In this embodiment, the second buckling structure includes two locks 102 and two second buckling parts 402. The two locks 102 are fixed at intervals on the side of the mechanical lock hook 100 facing the charging gun housing 400. Here, the connecting line of the two locks 102 is parallel to the central axis of the rotating shaft 101. The two second buckling parts 402 are fixed to the charging gun housing 400. At this time, the positions of the two second buckling parts 402 and the two locks 102 need to correspond one to one. The second buckling parts 402 and the corresponding locks 102 are matched and connected. Here, the lock 102 is provided with a mounting through hole. When the mechanical lock hook 100 and the charging gun housing 400 are installed, the second buckling part 402 is placed in the mounting through hole on the corresponding lock 102, and the second buckling part 402 has a certain movable spacing in the mounting through hole.

[0035] like Figure 1 、 Figure 2 、 Figure 4 As shown, the reset member 300 in this embodiment uses a spring. In order to achieve stable and quick installation of the spring by abutment, a first cross rib 103 is provided on the mechanical lock hook 100, and a second cross rib 405 is matched on the charging gun housing 400. The spring is fixed between the first cross rib 103 and the second cross rib 405. Example 2

[0036] This embodiment discloses a charging gun, which includes a charging gun body and the locking structure of the above-mentioned embodiment 1. Normally, a cylindrical inclined surface 104 is provided on the mechanical lock hook 100, and a micro switch 200 is installed in the slot 404 of the charging gun housing 400. When installing the micro switch 200 here, the micro switch 200 is inserted into the slot 404 and then fixed by glue. The mechanical lock hook 100 moves under force, and the cylindrical inclined surface 104 intermittently contacts the micro switch 200; in this embodiment, a hook head 106 is integrally installed on the side of the mechanical lock hook 100 away from the cable, wherein after the mechanical lock hook 100 and the charging gun housing 400 are installed, the hook end of the hook head 106 contacts the edge of the charging port of the charging gun housing 400.

[0037] In a further embodiment, a stop surface 406 is provided on the charging gun housing 400 to accurately limit the mechanical locking hook 100 .

[0038] Specific use:

[0039] As attached Figure 7 and Figure 8 As shown, the charging gun housing 400 and the mechanical lock hook 100 are squeezed and fixed. The first buckle 401 of the charging gun housing 400 is buckled above the rotating shaft 101 of the mechanical lock hook 100, limiting its position so that it can only rotate along the semicircular groove 403; the second buckle 402 of the charging gun housing 400 is buckled inside the lock 102 of the mechanical lock hook 100;

[0040] In the initial state, under the action of the spring force, the mechanical lock hook 100 is supported and kept horizontal, and the hook head 106 of the mechanical lock hook 100 is in a locked state;

[0041] After applying force to press the pressing surface 105 of the mechanical lock hook 100 until the stop surface 406 of the charging gun housing 400 stops the mechanical lock hook 100, the hook head 106 is lifted and in the unlocked state, and the charging port of the gun head is inserted into the socket of the vehicle. At this time, the mechanical lock hook 100 is released, and the hook head 106 cooperates with the limit piece on the vehicle body, and the gun head is fixed. At the same time, the cylindrical inclined surface 104 of the charging gun housing 400 triggers the micro switch 200 to transmit a signal to the vehicle.
