Description

Technical Field

[0001] The present application relates to a locking structure of a charging gun, and more particularly to a locking structure of a charging gun that can be locked without an additional lock. Background Art

[0002] With the popularity of electric vehicles, most public places are equipped with charging stations to charge electric vehicles. Although most charging guns are equipped with electronic locks, which will lock the charging gun when connected to the charging base, some charging guns may not be completely locked with the charging base and may become loose, which may cause the connector of the charging gun to burn and become unusable.

[0003] In addition, the problem that many car owners encounter when charging in public places is that the charging gun is pulled out by someone with ulterior motives, which may cause the vehicle to lock and be unable to start. This will not only cause trouble to the car owner, but may also damage the charging gun and affect the safety of charging.

[0004] Please refer to the Taiwan Patent No. TWM630372U applied by the applicant. Figure 1 , discloses a locking structure for a charging gun, which has a locking member 10 arranged on a shell 21 of a gun body 20, a positioning flange 22 surrounding the locking member 10, and a positioning groove 222 formed on the shell 21 so that the locking member 10 can be pressed up and down, and the pressing end of the locking member 10 is recessed to form a groove body, and the opening of the groove body is provided with a column 13 connecting the upper side and the lower side to form a ring body, and the user can set an additional lock on the ring body to prevent the locking member 10 from being arbitrarily removed. The defect of this structure is that the user needs to carry an additional lock to lock it. If the user does not carry an additional lock, the charging gun still has the chance to be removed by anyone, and its convenience of use needs to be improved. Utility Model Content

[0032] The positional relationships described in the following embodiments include: front, back, up, down, left and right. Unless otherwise specified, they are based on the directions of the components in the drawings. This application uses the direction of the charging gun 30 being plugged in as the front-to-back direction, and the direction of the locking member 40 being pressed as the up-down direction.

[0033] See also Figure 2 and Figure 3 , depicts a locking structure installed on a charging gun 30, including a locking seat 301 and a locking block 31 disposed on the locking seat 301. The upper surface of the charging gun 30 has a positioning flange 303 surrounding the locking member 40, and a positioning groove 302 is formed above the charging gun 30, and the positioning groove 302 allows the locking member 40 to be pressed up and down, and the specific structure of the charging gun 30 has been disclosed in the prior art and will not be repeated here.

[0034] In the embodiment of the present application, the locking seat 301 is arranged on the upper surface of the charging gun 30 and connected to the positioning flange 303. A channel 301a is formed inside the locking seat 301 and connected to a positioning groove 302 of the charging gun 30. The locking block 31 has a stop portion 31c movably arranged between the channel 301a and the positioning groove 302.

[0035] Further description, the locking block 31 also has an operating portion 31a, and a connecting wall 31b extending upward from the edge of the stop portion 31c and connected to the operating portion 31a, so that the locking block 31 is roughly U-shaped, and the length L2 of the stop portion 31c is slightly smaller than or equal to the length L3 of the channel 301a, and the length L1 of the operating portion 31a is smaller than the length L2 of the stop portion 31c, so that the user can move the setting position of the stop portion 31c through the operating portion 31a.

[0036] The upper wall of the locking seat 301 is formed with a limiting groove 301b. When the locking block 31 is set on the locking seat 301, the stopper 31c is located in the channel, the connecting wall 31b is located in the limiting groove 301b and moves along the wall of the limiting groove 301b, and the operating part 31a is located on the upper wall of the locking seat 301. In addition, a stopper 32 is set at an end of the locking seat 301 away from the positioning flange 303. The stopper 32 closes an open end of the channel 301a away from the positioning groove 302 to limit the movement of the locking block 31, so that the movement range of the locking block 31 is limited to between the channel 301a and the positioning groove 302, and prevents the locking block 31 from detaching from the locking seat 301. In the embodiment of the present application, the stopper 32 is screwed to the two wings of the locking seat 301 by screws, so that the stopper 32 is not easy to detach from the locking seat 301. In other embodiments, the stopper 32 may be fixed on the locking seat 301 via a snap-fit ​​structure.

[0037] See also Figure 4 When the locking block 31 is disposed on the locking seat 301, one side of the locking block 31 is in contact with the stopper 32. At this time, the space below the locking member 40 does not have a blocking structure, and the locking member 40 can still be pressed up and down to form an unlocked state.

[0038] See also Figure 5 When the user pushes the locking block 31 forward through the operating part 31a, the charging gun 30 is locked. At this time, the stopper 31c of the locking block 31 moves forward into the positioning groove 302, and the wall surface of the connecting wall 31b fits the bottom wall of the limiting groove 301b to form a stopper, so that the locking block 31 cannot move forward. At this time, the stopper 31c stays below the lock member 40 as a stopper structure, so that the lock member 40 cannot be pressed downward. When the user wants to unlock, the locking block 31 is pushed backward to form an unlocked state.

[0039] The present application uses a locking block 31 that can move between the channel 301a and the positioning groove 302 to limit the pressing of the locking member 40 to achieve a stopping effect. Even if the user does not carry an additional lock, the locking structure on the charging gun 30 can be used to lock it, thereby improving the convenience of use.

[0040] The embodiments and / or implementation methods described above are only used to illustrate the preferred embodiments and / or implementation methods for realizing the technology of the present application, and are not intended to limit the implementation methods of the technology of the present application in any form. Any technical personnel in this field may make slight changes or modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the present application, but they should still be regarded as technologies or embodiments that are essentially the same as the present application.
