Description

Technical Field

[0001] This utility model relates to the field of new energy charging pile technology, specifically a protection mechanism for the charging gun head socket of a new energy charging pile. Background Technology

[0002] The main function of a new energy charging pile is to store enough electricity for electric vehicles to support their operation. It obtains electrical energy from the power grid and then transmits it to the battery of the electric vehicle. The power input end of the charging pile is connected to the AC power grid, while the power output end is connected to the electric vehicle through a charging plug to realize the charging process.

[0003] Currently, most existing home-use new energy charging piles are not equipped with a fixing mechanism for the charging gun, which means that the charging gun can often be pulled out at will, potentially leading to damage to the charging gun. In view of this, we propose a protection mechanism for the charging gun head socket of new energy charging piles. Utility Model Content

[0004] The main purpose of this utility model is to provide a protection mechanism for the charging gun head socket of new energy charging piles, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a protection mechanism for the charging gun inlet of a new energy charging pile, comprising a charging pile body, a charging gun connected to the charging pile body via a cable, a fixing groove formed in the charging gun, and a fixing mechanism on the charging pile, the fixing mechanism comprising:

[0006] The socket is slidably connected to a spring-loaded latch.

[0007] A rotating ring, wherein an extrusion groove is formed on the inner wall of the rotating ring and a limiting groove is formed on the outer wall at the upper end of the rotating ring;

[0008] A combination lock, wherein the combination lock is penetrated by a shaft and rotatably connected to the shaft, a groove is provided on the outer wall of the side end of the combination lock, and an elastic limiting rod is provided directly below the groove. The elastic limiting rod penetrates a socket and is slidably connected to the socket. A ball is provided on the top of the elastic limiting rod to reduce the friction between the elastic limiting rod and the combination lock.

[0009] Preferably, a guide rod is fixedly connected to the inner wall of the socket, and the guide rod passes through the rotating ring and is slidably connected to the rotating ring.

[0010] Preferably, the socket is slidably connected to an elastic pressing block, and a limit block is fixedly connected to the outer wall of the elastic pressing block.

[0011] Preferably, one end of the rotating ring is fixedly connected to the outer wall of the ring, and the other end of the ring is fixedly connected to the inner wall of the socket.

[0012] Preferably, a handle is fixedly connected to the outer wall of the rotating ring, and the handle has a slot.

[0013] Preferably, the combination lock has four sets, which are evenly distributed on the outer wall of the shaft.

[0014] This utility model provides a protective mechanism for the charging gun head socket of new energy charging piles. It has the following beneficial effects:

[0015] (1) The protection mechanism for the charging gun socket of the new energy charging pile is designed with a combination lock, a rotating ring, and an elastic limit rod. Only when the combination lock is rotated to the correct number, so that the groove and the elastic limit rod are aligned and the elastic limit rod is disengaged from the limit groove, can the limit of the rotating ring be released, and the charging gun can be pulled out in the subsequent process. This effectively prevents the charging gun from being pulled out by others when it is not in use, avoiding the risk of equipment damage. At the same time, the combination lock also increases the convenience of use. Users only need to remember the password to operate easily without having to carry an extra key or tool.

[0016] (2) The protective mechanism for the charging gun head socket of the new energy charging pile is designed with elastic blocks and fixing grooves. When the charging gun is inserted into the socket, its outer wall will squeeze the elastic blocks so that they are completely inserted into the socket and spring into the fixing groove under the action of the spring force, thus achieving a firm fixation of the charging gun.

[0031] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-11 This utility model proposes a protection mechanism for the charging gun head socket of a new energy charging pile, including a charging pile body 1, a charging gun 2 connected to the charging pile body 1 via a cable, a fixing groove 21 provided in the charging gun 2, and a fixing mechanism on the charging pile.

[0034] In this embodiment of the utility model, in order to fix the charging gun 2, the fixing mechanism specifically includes a socket 31, the socket 31 being slidably connected to an elastic locking block 311, and the inner wall of the rotating ring 32 having a pressing groove 320, such as... Figure 9 As shown, the compression groove 320 is composed of a vertical groove and an arc-shaped groove. The function of the vertical groove is that when the charging gun 2 compresses the elastic block 311, the elastic block 311 can move upward along the vertical groove, thereby allowing the elastic block 311 to fully enter the socket 31. The function of the arc-shaped groove is that when the rotating ring 32 rotates, the arc-shaped groove will compress the protrusion on the elastic block 311, causing the elastic block 311 to disengage from the fixing groove 21, thereby releasing the limiting position of the charging gun 2. A limiting groove 324 is formed on the upper outer wall of the rotating ring 32. The combination lock 33 is penetrated by the shaft 331 and is connected to the shaft 331. The combination lock 33 is rotated and has four sets, which are evenly distributed on the outer wall of the shaft 331. Numbers are written on the outer wall of the combination lock 33. Only when the corresponding number is rotated can the groove 332 coincide with the elastic limit rod 333, so that the elastic limit rod 333 enters the groove 332 under the elastic action of the spring, and then the elastic limit rod 333 disengages from the limit groove 324. The outer wall of the side end of the combination lock 33 has a groove 332, and the elastic limit rod 333 is located directly below the groove 332. The elastic limit rod 333 passes through the socket 31 and is slidably connected to the socket 31.

[0035] A guide rod 312 is fixedly connected to the inner wall of the socket 31. The guide rod 312 passes through the rotating ring 32 and is slidably connected to the rotating ring 32. An elastic pressing block 313 is slidably connected to the socket 31. A limit block 314 is fixedly connected to the outer wall of the elastic pressing block 313. One end of an arc spring 323 is fixedly connected to the outer wall of the rotating ring 32. The other end of the arc spring 323 is fixedly connected to the inner wall of the socket 31. A handle 321 is fixedly connected to the outer wall of the rotating ring 32. The handle 321 has a slot 322.

[0036] In this invention, when the charging gun needs to be removed, the combination lock 33 is rotated sequentially. When the combination lock 33 is rotated to the correct number, the groove 332 of the combination lock 33 coincides with the elastic limiting rod 333. At this time, the elastic limiting rod 333 will spring upward into the groove 332 under the elastic force of the spring, causing the elastic limiting rod 333 to disengage from the limiting groove 324, thereby releasing the limiting of the rotating ring 32. Then, the handle 321 is rotated, and the arc spring 323 undergoes elastic deformation. During this process, the compression groove 320 will compress the protrusion on the elastic locking block 311. This causes the elastic block 311 to move upward, disengaging it from the fixed groove 21 and releasing the limit of the charging gun 2. Then, the charging gun 2 is inserted into the tram interface for charging. Meanwhile, during the rotation of the rotating ring 32, the handle 321 will press the limiting block 314 on the elastic pressing block 313, causing the elastic pressing block 313 to fully enter the socket 31. When the slot 322 on the handle 321 coincides with the limiting block 314, the limiting block 314 will be locked into the slot 322 under the elastic force of the spring, thus completing the limitation of the rotating ring 32.

[0037] When charging is complete, first press the elastic pressing block 313 to disengage the limiting block 314 from the slot 322. At this time, the rotating ring 32 will return to its original position under the elastic force of the arc spring 323. Figure 10 As shown, the charging gun 2 is then inserted into the socket 31. During this process, the outer wall of the charging gun 2 returns to the elastic block 311 and is squeezed, so that the elastic block 311 is fully inserted into the socket 31. When the charging gun 2 is fully inserted into the socket 31, the elastic block 311 will spring into the fixing groove 21 under the action of the spring force, thereby completing the limitation of the charging gun 2. Then, the combination lock 33 is rotated in sequence. When the combination lock 33 is rotated, the groove 332 opened by the combination lock 33 will squeeze the elastic limiting rod 333, so that the elastic limiting rod 333 passes through the base and inserts into the limiting groove 324, thereby limiting the rotating ring 32 and preventing the charging gun 2 from being pulled out by others when it is not in use.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
