Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, and in particular to a charging gun head locking device. Background Technology

[0002] After using the charging gun for new energy vehicles, it needs to be inserted into the charging station's socket and secured to prevent it from swinging around and to facilitate future use, thus preventing damage to the charging gun head. Although current charging stations are equipped with mechanical or electromagnetic fixing mechanisms to secure the charging gun head after insertion and prevent it from falling out, these mechanisms only work after the charging gun head is fully inserted into the socket. However, in actual use, due to operator unfamiliarity with the insertion and removal of the charging gun head, the operator may release the charging gun head before it is fully inserted into the socket, resulting in incomplete insertion. This may prevent the fixing mechanism from being triggered, making it unable to position the charging gun head properly and causing it to fall out easily. Based on the above situation, we propose a charging gun head locking device to solve the above problems. Utility Model Content

[0003] This utility model provides a charging gun head locking device to solve the problem in the prior art that the charging gun head cannot be fixed because it is not properly inserted.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] A charging gun head locking device includes a charging pile and a gun head body. The charging pile has a mounting base at the socket position. The mounting base has a receiving groove inside and a vertical groove communicating with the receiving groove. The gun head body has a receiving ring with an outer diameter equal to the inner diameter of the receiving groove. The mounting base also has a locking actuator. When the gun head body is installed inside the mounting base, the locking actuator locks the gun head body in the socket of the charging pile.

[0006] Preferably, the locking actuator includes a telescopic member whose fixed end is connected to the inner wall of the receiving groove, a pressure sensor installed at the bottom of the vertical groove, and a controller electrically connected to the pressure sensor and the telescopic member. The controller controls the telescopic member to abut against the receiving ring to lock the gun head body after receiving the pressure signal from the pressure sensor.

[0007] Preferably, the locking actuator further includes an operating rod connected to a pressure sensor, one end of which extends to the outside of the mounting base, and a sliding cavity is provided inside the mounting base, with a spring connecting the bottom end of the pressure sensor to the sliding cavity.

[0008] Preferably, the receiving ring is provided with a sealing ring, and the charging pile is provided with a sealing groove corresponding to the sealing ring at the position near the plug.

[0009] Preferably, the bottom of the receiving groove is provided with a receiving slide rail, and the bottom of the gun head body is provided with a slide bar that can slide on the receiving slide rail.

[0010] Preferably, the width of the vertical groove is smaller than the inner diameter of the receiving groove.

[0011] The beneficial effects of this utility model are: by initially placing the gun head body in the receiving groove, it can prevent the gun head body from falling due to improper placement. At the same time, the locking mechanism in the receiving groove can be activated by the gravity of the gun head body to lock the gun head body inside the charging pile's socket, further improving the locking effect of the gun head body.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Reference Figures 1-5 As shown, a charging gun head locking device includes a charging pile 1 and a gun head body 2. The charging pile 1 has a mounting base 3 at its socket position. The mounting base 3 has a receiving groove 31 inside, and a vertical groove 32 communicating with the receiving groove 31 is formed on the mounting base 3. The width of the vertical groove 32 is smaller than the inner diameter of the receiving groove 31. The gun head body 2 has a receiving ring 33 with an outer diameter equal to the inner diameter of the receiving groove 31. When installing the gun head body 2 onto the charging pile 1, the gun head body 2 is first inserted into the vertical groove 32. The receiving ring 33 is positioned within the receiving groove 31 to receive the gun head body 2, preventing it from accidentally falling off. The vertical groove 32 further limits the receiving plate, preventing the gun head body 2 from detaching from the mounting base 3, thus pre-positioning the gun head body 2 when it is installed on the charging pile 1. In addition, the mounting base 3 is also equipped with a locking actuator, which locks the gun head body 2 into the socket of the charging pile 1 when the gun head body 2 is installed inside the mounting base 3.

[0021] Specifically, the locking actuator includes a telescopic member 4 whose fixed end is connected to the inner wall of the receiving groove 31, a pressure sensor 41 installed at the bottom of the vertical groove 32, and a controller 42 electrically connected to the pressure sensor 41 and the telescopic member 4. When the gun head body 2 is placed inside the mounting base 3, the weight of the gun head body 2 causes it to press down against the pressure sensor 41, causing the pressure sensor 41 to generate a pressure signal and transmit the pressure signal to the controller 42. After receiving the pressure signal from the pressure sensor 41, the controller 42 controls the telescopic member 4 to extend and press against the receiving ring 33, thereby moving the gun head body 2 into the charging post socket and locking the gun head body 2.

[0022] The locking mechanism also includes an operating rod 43 connected to the pressure sensor 41. One end of the operating rod 43 extends to the outside of the mounting base 3, and a sliding cavity 44 is provided inside the mounting base 3. A spring 45 is connected between the bottom end of the pressure sensor 41 and the sliding cavity 44. When it is necessary to remove the gun head body 2 from the charging pile 1 socket, while holding the gun head body 2, the operating rod 43 can be pressed down with other fingers to make the operating rod 43 drive the pressure sensor 41 to compress the spring 45 and move downward, so that the pressure sensor 41 is not compressed by the gun head body 2. At this time, the controller 42 controls the telescopic component 4 to retract, releasing the resistance to the receiving ring 33, thereby facilitating the removal of the gun head body 2. The telescopic component 4 can be an electric telescopic rod or an electric push rod, etc.

[0023] Furthermore, such as Figure 2As shown, the receiving ring 33 is provided with a sealing ring 5, and the charging pile 1 is provided with a sealing groove 51 corresponding to the sealing ring 5 near the socket. When the gun head body 2 enters the socket of the charging pile 1, the sealing ring 5 on the receiving ring 33 is inserted into the sealing groove 51 to seal the socket of the charging pile 1, so as to reduce the entry of external dust, rainwater and other substances.

[0024] Among them, such as Figure 2 as well as Figure 3 As shown, the bottom of the receiving groove 31 is provided with a receiving slide rail 6, and the bottom of the gun head body 2 is provided with a slide bar 61 that can slide on the receiving slide rail 6. When the gun head body 2 is placed in the receiving groove 31, the slide bar 61 is located in the receiving slide rail 6. Thus, when the telescopic member 4 pushes the gun head body 2 to move, the gun head body 2 can slide on the receiving slide rail 6. At the same time, the cross-sectional width of the receiving slide rail 6 gradually increases from bottom to top, so that when the gun head body 2 drives the slide bar 61 to be placed in the receiving groove 31, the slide bar 61 can more easily enter the receiving slide rail 6.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
