Description
Technical Field
[0001] This utility model relates to a protection device, and more particularly to a protection device for preventing accidental contact with an automotive charging interface, belonging to the field of electric vehicle charging technology. Background Technology
[0002] With the booming development of the new energy vehicle industry, the safety and reliability of car charging interfaces, as the key connection hub between vehicles and charging equipment, are receiving increasing attention. However, some car charging interfaces on the market still have many shortcomings in their anti-accidental contact design, posing potential risks to users' charging safety.
[0003] Traditional charging interfaces lack effective physical protection structures. Some charging interfaces are simply designed and rely solely on simple flip covers for protection. These flip covers are easily opened and cannot effectively prevent children or non-professionals from accidentally touching the internal terminals. This can not only damage the charging interface and the vehicle's electrical system, but may also endanger personal safety.
[0004] In addition, in scenarios such as charging in the rain, washing vehicles, or parking outdoors, as well as in environments with a lot of sand and dust, dust can easily accumulate inside the charging interface. This not only affects the conductivity between the interface and the charging gun, leading to problems such as reduced charging efficiency, charging interruption, or poor contact, but also accelerates the oxidation and corrosion of the metal components inside the interface, shortening the lifespan of the charging interface and reducing its long-term reliability.
[0005] Therefore, it is urgent to improve the protection device for preventing accidental contact of car charging interfaces in order to solve the above-mentioned problems. Utility Model Content
[0006] The purpose of this invention is to provide a protective device for car charging interfaces to prevent accidental contact. The steel sheet and sealing rubber form a composite structure of "rigid + flexible". The sealing rubber can seal the port of the charging gun connector without manual operation, thereby reducing accidental contact between the hand and the charging interface, improving safety during use, and preventing rainwater, dust and other substances from entering the charging slot during sealing, thus extending the service life of the charging head.
[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include: A car charging interface protection device to prevent accidental contact includes a vehicle body charging port and a charging gun connector opened inside the vehicle body charging port. The charging gun connector has a charging slot, and a brake chamber connected to the charging slot is opened inside the vehicle body charging port. A drive mechanism is fixedly installed inside the brake chamber. The drive mechanism includes a dual-output-shaft steel plate drive motor and a sealed rubber drive motor. The output end of the dual-output-shaft steel plate drive motor is provided with a steel plate fixing head. The sealed rubber drive motor is provided with a sealing rubber. The end of the sealing rubber away from the sealed rubber drive motor is fixedly connected to one end of the steel plate by a fastening bolt. The inner side of the charging slot is provided with a rubber groove, and the rubber groove extends into the interior of the brake chamber. The sealing rubber is slidably disposed inside the rubber groove.
[0008] Preferably, the dual-output-shaft steel plate drive motor is fixedly installed inside the brake chamber, and the steel plate is fixedly installed at the output end of the dual-output-shaft steel plate drive motor through a steel plate fixing head.
[0009] Preferably, the sealing rubber drive motor is used to wind up the sealing rubber, and both ends of the sealing rubber drive motor are fixedly installed inside the brake chamber by motor fixing brackets.
[0010] Preferably, both the dual-output-shaft steel plate drive motor and the sealed rubber drive motor are electrically connected to the vehicle's power supply via wires. A brake switch is electrically connected to both the dual-output-shaft steel plate drive motor and the sealed rubber drive motor, and the brake switch is fixedly installed inside the vehicle's charging port.
[0011] Preferably, the charging slot is internally equipped with a slow charging connector and a fast charging connector.
[0012] Preferably, the charging port of the vehicle body is provided with a rotatable charging port sealing cover inside, and the charging port sealing cover is rotatably connected to the charging port of the vehicle body through a rotating support arm.
[0013] Preferably, the outer surface of the sealing rubber is coated with a waterproof coating.
[0014] Preferably, the sealing rubber is internally fixed with a plurality of evenly distributed metal support rods.
[0015] This utility model has at least the following beneficial effects: 1. The steel sheet is directly driven by the steel sheet fixing head, providing high torque output. The sealing rubber drive motor drives the sealing rubber to move, realizing flexible drive and avoiding the impact of rigid connection on precision components. The steel sheet and sealing rubber are fixedly connected by fastening bolts to form a "rigid + flexible" composite structure. The steel sheet bears the main load and ensures structural stability, while the sealing rubber absorbs vibration, compensates for errors, reduces component wear, and improves structural strength and the stability of the sealing rubber's movement.
[0016] 2. After starting the dual-output shaft steel plate drive motor and the sealing rubber drive motor, the port of the charging gun connector can be sealed by the sealing rubber. Compared with the traditional sealing cover, there is no need to manually seal the charging interface, thereby reducing accidental contact between the hand and the charging interface and improving the safety of use. At the same time, when not charging, the port of the charging gun connector is sealed by the sealing rubber to prevent rainwater, dust and other substances from entering the inside of the charging slot and extend the service life of the charging head.

[0019] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0020] like Figures 1-6As shown, the car charging interface protection device for preventing accidental contact provided in this embodiment includes a vehicle body charging port 1 and a charging gun connector 2 opened inside the vehicle body charging port 1. The charging gun connector 2 is provided with a charging slot 201. The vehicle body charging port 1 is provided with a brake chamber 101 connected to the charging slot 201. A drive mechanism 3 is fixedly installed inside the brake chamber 101. The structure is simple, can charge quickly, improve the convenience of use, and isolate the drive mechanism 3 from the charging slot 201 to prevent rainwater, dust and other substances from entering the electrical component area, extend the equipment life and reduce the risk of short circuit. The drive mechanism 3 includes a dual-output shaft steel plate drive motor 301 and a sealed rubber drive motor 302. The output end of the dual-output shaft steel plate drive motor 301 is provided with a steel plate fixing head 3011. The sealed rubber drive motor 302 is provided with a sealing rubber 3021. The end of the sealing rubber 3021 away from the sealed rubber drive motor 302 is fixedly connected to one end of the steel plate 3012 by a fastening bolt 4. The steel plate fixing head 3011 directly drives the steel plate 3012 to provide high torque output. The sealed rubber drive motor 302 drives the sealing rubber 3021 to move, realizing flexible drive and avoiding the impact of rigid connection on precision components. The steel sheet 3012 and the sealing rubber 3021 are fixedly connected by fastening bolts 4 to form a "rigid + flexible" composite structure. The steel sheet 3012 bears the main load and ensures the structural stability. The sealing rubber 3021 absorbs vibration, compensates for errors, and reduces component wear. The inner side of the charging slot 201 is provided with a rubber groove 204, which extends into the brake chamber 101. The sealing rubber 3021 is slidably disposed inside the rubber groove 204. After the dual-output shaft steel sheet drive motor 301 and the sealing rubber drive motor 302 are started, the port of the charging gun connector 2 can be sealed by the sealing rubber 3021. Compared with the traditional sealing cover, there is no need to manually seal the charging interface, thereby reducing accidental contact between the hand and the charging interface and improving the safety of use. At the same time, when not charging, the port of the charging gun connector 2 is sealed by the sealing rubber 3021 to prevent rainwater, dust and other substances from entering the interior of the charging slot 201 and extend the service life of the charging head. In addition, such as Figure 1 As shown, both the dual-output shaft steel plate drive motor 301 and the sealed rubber drive motor 302 are electrically connected to the vehicle's power supply via wires. A brake switch 6 is electrically connected to both the dual-output shaft steel plate drive motor 301 and the sealed rubber drive motor 302. The brake switch 6 is fixedly installed inside the vehicle's charging port 1. In order to improve the efficiency of the drive mechanism 3, the brake switch 6 directly controls the on / off state of the dual-output shaft steel plate drive motor 301 and the sealed rubber drive motor 302, improving the ease of use and reducing accidental contact between the hand and the charging connector.
[0021] Furthermore, such as Figure 1As shown, the dual-output shaft steel plate drive motor 301 is fixedly installed inside the brake chamber 101, and the steel plate 3012 is fixedly installed at the output end of the dual-output shaft steel plate drive motor 301 through the steel plate fixing head 3011. The dual-output shaft steel plate drive motor 301 is fixedly installed inside the brake chamber 101 to improve the stability of the dual-output shaft steel plate drive motor 301. The sealing rubber drive motor 302 is used to wind up the sealing rubber 3021. Both ends of the sealing rubber drive motor 302 are fixedly installed inside the brake chamber 101 through the motor fixing bracket 3022 to improve the stability of the sealing rubber drive motor 302. The brake chamber 101 is in a sealed state, which further improves the service life of the dual-output shaft steel plate drive motor 301 and the sealing rubber drive motor 302.
[0022] Furthermore, such as Figure 1 As shown, the charging slot 201 is internally equipped with a slow charging connector 202 and a fast charging connector 203. The slow charging connector 202 is used for long-term parking scenarios, uses lower power, has a small load on the power grid, low charging cost, and can reduce the risk of battery thermal runaway and extend battery life. The fast charging connector 203 is suitable for emergency charging scenarios, uses high power, and improves efficiency. Therefore, the overall charging flexibility and scope of use are improved. The charging port 1 on the vehicle body is equipped with a rotating charging port sealing cover 5. The charging port sealing cover 5 is rotatably connected to the charging port 1 on the vehicle body through a rotating support arm 501. The rotating charging port sealing cover 5 design provides excellent sealing and dust prevention, is convenient to open and close, and is durable, thereby improving charging safety and experience.
[0023] Furthermore, such as Figure 1 and Figure 2 As shown, the outer surface of the sealing rubber 3021 is coated with a waterproof coating. This coating enhances the waterproof and moisture-proof properties, blocks corrosive media, and extends the service life. Several evenly distributed metal support rods 3023 are fixedly installed inside the sealing rubber 3021. The uniformly distributed metal support rods 3023 significantly improve structural strength, effectively resist external pressure deformation, and ensure stable operation. The evenly distributed metal support rods 3023 are embedded in the sealing rubber 3021, enhancing fatigue resistance. While providing stable support, they do not affect the sealing effect, achieving functional synergy optimization.
[0024] like Figures 1-6 As shown, the principle of the car charging interface protection device to prevent accidental touches provided in this embodiment is as follows: The drive mechanism 3 is isolated from the charging tank 201 to prevent rainwater, dust and other substances from entering the electrical component area, thereby extending the equipment life and reducing the risk of short circuits. The steel plate 3012 is directly driven by the steel plate fixing head 3011, providing high torque output. The sealed rubber drive motor 302 drives the sealed rubber 3021 to move, realizing flexible drive and avoiding the impact of rigid connection on precision components. The steel sheet 3012 and the sealing rubber 3021 are fixedly connected by the fastening bolts 4, forming a "rigid + flexible" composite structure. The steel sheet 3012 bears the main load and ensures the stability of the structure, while the sealing rubber 3021 absorbs vibration, compensates for errors, and reduces component wear. After starting the dual-output shaft steel sheet drive motor 301 and the sealing rubber drive motor 302, the port of the charging gun connector 2 can be sealed by the sealing rubber 3021. Compared with the traditional sealing cover, there is no need to manually seal the charging interface, thereby reducing accidental contact between the hand and the charging interface and improving the safety of use. At the same time, when not charging, the port of the charging gun connector 2 is sealed by the sealing rubber 3021 to prevent rainwater, dust, etc. from entering the interior of the charging slot 201 and extend the service life of the charging head.
