[0002] The safety switch for electric vehicles is a crucial component ensuring safe operation. The charging port is an interface installed on the electric vehicle for connecting to the charger; its main function is to provide a path for charging current, enabling the transfer of electrical energy from the charger to the electric vehicle's battery. The plug is the component on the charger used to insert into the charging port.

[0003] Existing electric vehicle plugs and sockets typically rely on simple plugging and unplugging for connection. During charging, external force can easily cause the plug to loosen or even detach, leading to charging interruptions or unstable electrical connections, affecting charging efficiency, and potentially causing electrical malfunctions. Furthermore, traditional electric vehicle plugs and sockets require users to manually pull them out. When the resistance between the plug and socket increases due to prolonged use, dust accumulation, or other reasons, users may need to use considerable force, which can easily bend or damage the pins on the plug or socket, affecting normal use and potentially creating safety hazards.

[0004] Therefore, it is necessary to invent a safety switch for electric vehicles to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a safety switch for electric vehicles to address the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle safety switch, including a socket and a plug, wherein the front end of the plug is adapted to the front end of the socket and can be plugged in and connected, an electric push rod is provided on the outside of the tail end of the socket, and a touch switch is provided on one side of the outside of the tail end of the socket.

[0007] Both sides of the socket are provided with locking blocks, and spring rods are horizontally fixed to the outside of both locking blocks;

[0008] The plug has guide grooves on both sides, and the inner walls of the two guide grooves have snap-fit ​​openings. Partition strips are slidably installed in the guide grooves on both sides of the plug. The tail ends of the two partition strips movably pass through both sides of the tail end of the plug. A collar is movably sleeved on the tail end of the plug, and the two ends of the collar are fixedly connected to the tail ends of the two partition strips respectively.

[0009] As a preferred embodiment of this utility model, a through hole is provided at the middle position of the tail end of the socket, the electric push rod is placed horizontally, the output of the electric push rod is inserted into the through hole, and the output end of the electric push rod can pass through the through hole.

[0010] As a preferred embodiment of this utility model, a notch is provided on one side of the tail end of the socket, the control contact of the touch switch is located in the notch, the control contact of the touch switch corresponds to the guide groove on the same side of the plug, and one of the partition strips corresponds to the control contact of the touch switch.

[0011] As a preferred embodiment of this utility model, the card block has a wedge-shaped structure, the card slot is adapted to the card block, the front inclined surface of the card block is located in the card slot, and the socket has through slots on both sides, and the two card blocks are respectively movably inserted into the slots on both sides of the socket.

[0012] As a preferred embodiment of this utility model, the socket is fixedly installed with connecting parts on both sides of the front end, and the socket is fixedly installed on the electric vehicle through the connecting parts on both sides.

[0013] As a preferred embodiment of this utility model, the tail pin of the touch switch is electrically connected to the electric push rod via a wire, and both the partition strip and the collar are made of insulating material, with the front end width of the partition strip being greater than the tail end width.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By setting locking blocks and spring rods on both sides of the socket, and setting locking slots and partition strips on both sides of the plug, the connection between the plug and the socket is more stable and less likely to separate.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The electric vehicle safety switch shown includes a socket 1 and a plug 2. The front end of the plug 2 is adapted to the front end of the socket 1 and can be plugged in. An electric push rod 4 is provided on the outside of the tail end of the socket 1, and a touch switch 5 is provided on one side of the outside of the tail end of the socket 1.

[0026] Both sides of the socket 1 are provided with locking blocks 3, and spring rods 31 are horizontally fixed to the outside of the two locking blocks 3.

[0027] Both sides of the plug 2 are provided with guide grooves 24, and the inner walls of both guide grooves 24 are provided with slots 23. Partition strips 21 are slidably installed in both guide grooves 24 of the plug 2. The guide grooves 24 facilitate the back and forth movement of the partition strips 21, so that the plug 2 is inserted into the socket 1 more smoothly and accurately. The tail ends of the two partition strips 21 are movable through both sides of the tail end of the plug 2. The tail end of the plug 2 is movably sleeved with a collar 22, and the two ends of the collar 22 are fixedly connected to the tail ends of the two partition strips 21 respectively.

[0028] In this example, the locking block 3 has a wedge-shaped structure. When the plug 2 is inserted into the socket 1, the inclined front end of the locking block 3 slides into the slot 23 along the guide groove 24 under the elastic force of the spring rod 31. This design creates a reliable mechanical connection between the plug 2 and the socket 1, effectively enhancing the stability of the connection. During the electric vehicle's operation, even if subjected to bumps, vibrations, or external pulling, the plug 2 is not easily loosened or detached, avoiding problems such as charging interruption and unstable electrical connection, ensuring the smooth progress of the charging process, improving charging efficiency, and reducing the risk of electrical failures caused by unstable connection. The spring rod 31 has a certain degree of elasticity, which can act as a buffer when the plug 2 is inserted and removed. When the plug 2 is inserted, the spring rod 31 can adapt to the insertion force of the plug 2, allowing the locking block 3 to smoothly engage with the slot 23.

[0029] Furthermore, in the above technical solution, a through hole 13 is provided at the middle position of the end of the socket 1, the electric push rod 4 is placed horizontally, the output of the electric push rod 4 is inserted into the through hole 13, and the output end of the electric push rod 4 can pass through the through hole 13.

[0030] Furthermore, in the above technical solution, a notch 14 is provided on one side of the tail end of the socket 1, the control contact of the touch switch 5 is located in the notch 14, the control contact of the touch switch 5 corresponds to the guide groove 24 on the same side of the plug 2, and a partition strip 21 corresponds to the control contact of the touch switch 5.

[0031] In this example, when the charging connection needs to be disconnected, the push ring 22 moves the partition strip 21 along the guide groove 24 towards the bottom. When the front end of the partition strip 21 touches the bottom and contacts the control contact of the touch switch 5, the pin at the tail end of the touch switch 5 is electrically connected to the electric push rod 4 through a wire, thereby transmitting a signal to the electric push rod 4, controlling the electric push rod 4 to start. Its output end pushes the front end of the plug 2 forward, realizing the automatic separation of the plug 2 from the socket 1. This avoids the user manually using brute force to pull out the plug 2, prevents the pins on the plug or socket from bending or being damaged due to excessive insertion and removal resistance, extends the service life of the plug 2 and the socket 1, and also ensures the stability and safety of the electrical connection.

[0032] Furthermore, in the above technical solution, the card block 3 has a wedge-shaped structure, the slot 23 is adapted to the card block 3, the front inclined surface of the card block 3 is located in the slot 23, and the socket 1 has through slots 11 on both sides, and the two card blocks 3 are respectively movably inserted into the slots 11 on both sides of the socket 1.

[0033] Furthermore, in the above technical solution, connecting parts 12 are fixedly installed on both sides of the front end of the socket 1. The socket 1 is fixedly installed on the electric vehicle through the connecting parts 12 on both sides. The electric push rod 4 is horizontally installed inside the electric vehicle and corresponds to the tail end of the socket 1. The socket 1 can be firmly installed on the electric vehicle through the connecting parts 12. This design ensures that the socket 1 will not loosen or shift during the operation of the electric vehicle, ensuring the stability and reliability of the connection between the plug 2 and the socket 1. It also facilitates the installation and disassembly of the socket 1, making subsequent maintenance and replacement convenient.

[0034] Furthermore, in the above technical solution, the tail pin of the touch switch 5 is electrically connected to the electric push rod 4 through a wire, and both the partition strip 21 and the collar 22 are made of insulating material, with the front end width of the partition strip 21 being greater than the tail end width.

[0035] The electric vehicle safety switch provided by this utility model operates as follows:

[0036] The partition strip 21 can slide within the guide groove 24. When the plug 2 needs to be unplugged, the collar 22 is pushed, causing the partition strip 21 to slide within the guide groove 24. This allows the front end of the partition strip 21 to push the locking block 3 out of the locking slot 23, releasing the locking block 3 from the locking slot 23. Simultaneously, the partition strip 21 can also trigger the touch switch 5, controlling the electric push rod 4 to separate the plug 2 from the socket 1, thus facilitating the unplugging process. Both the partition strip 21 and the collar 22 are made of insulating material, which not only prevents electric shock during operation but also avoids safety hazards caused by electrical leakage. Furthermore, the design of the front end of the partition strip 21 being wider than its rear end better facilitates the separation of the locking block 3 and the triggering of the touch switch 5, improving the accuracy and reliability of the operation.

[0037] The electric push rod 4 can be connected to the intelligent control system of the electric vehicle to achieve remote control and automated operation. For example, after charging is complete, the electric vehicle control system can automatically trigger the electric push rod 4 to disconnect the charging connection, improving the convenience and intelligence of use. The touch switch 5 can serve as a safety protection mechanism. During charging, if an abnormal situation occurs requiring emergency disconnection, the touch switch 5 can be triggered by touching the isolation strip 21, causing the electric push rod 4 to immediately act and quickly disconnect the plug 2 from the socket 1, preventing safety accidents.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
