Description

Technical Field

[0001] The present invention relates to the technical field of high-current plugs, in particular to a high-current plug with a motor unlocking structure. Background Art

[0002] Traditional high-current plugs mostly use manual plugging and unplugging or simple mechanical locking structures. These can easily lead to poor contact and accidental loosening during frequent plugging and unplugging or in vibrating environments, resulting in safety hazards such as arcing and overheating. While there are electric-driven plugs in the prior art, these lack multiple locking protection mechanisms and are insufficiently waterproof and designed to prevent misoperation, making it difficult to meet the stringent safety and stability requirements of industrial scenarios. To this end, the present invention proposes a high-current plug that integrates motor-driven unlocking, electronic lock dual protection, and environmental protection. Summary of the Invention

[0003] The object of the present invention is to solve at least one of the technical drawbacks.

[0004] To this end, one object of the present invention is to provide a high-current plug with a motor unlocking structure to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, an embodiment of one aspect of the present invention provides a high-current plug with a motor unlocking structure, comprising a plug structure, a plug end surface of the plug structure having a plurality of female plug pins fixedly connected thereto, and a plug end surface of the plug structure having a plurality of signal pins fixedly connected thereto; The two sides of the plug structure are rigidly connected to spur racks, and the sides of the spur racks are movably connected to gears, which rotate under the drive of an external motor; The front and back sides of the plug structure are provided with locking holes, and the locking holes can be plugged with electronic lock pins after the plug structure is moved into place. The electronic lock pins are driven by an external electronic lock.

[0006] Preferably, any of the above solutions is that a guide post and a guide groove are provided on the top and bottom of the plug structure respectively, wherein the end of the guide post is a tapered structure.

[0007] Preferably, any of the above solutions is that the plugging end face of the plug structure is provided with an annular waterproof sealing ring, and the waterproof sealing ring is made of high-temperature resistant silicone material.

[0008] Preferably, any of the above solutions has a position sensor built into the plug structure, and the position sensor is connected to a control system signal of an external motor.

[0009] Preferably, from any of the above solutions, both sides of the plug structure are rigidly connected to the spur rack via pins.

[0010] Preferably, the female pins of the plug are silver-plated copper alloy with a cross-sectional area of ​​no less than 6 mm². This ensures low resistance and high corrosion resistance during high-current transmission, preventing overheating due to poor contact. The signal pins are symmetrically located on both sides of the midplane of the plug structure, transmitting control signals and physically isolating them from the female pins to prevent signal interference.

[0011] In any of the above solutions, preferably, two plug signal pins are symmetrically distributed about the midplane of the plug structure. When the external motor is activated, the gear engages the spur rack, pushing the plug structure in a linear motion to complete insertion or removal. A position sensor, such as a Hall effect sensor, is integrated within the plug structure to monitor plug displacement in real time and provide feedback to the motor control system, enabling precise positioning. Once the plug structure is in position, the external electronic lock drives the electronic lock pin into the locking hole.

[0012] This high-current plug has a good safety locking mechanism and cannot be manually plugged in or out, with high reliability and good safety.

[0013] This design is suitable for scenarios with high current and high reliability requirements, such as electric vehicle charging piles, industrial robots, and power distribution cabinets.

[0014] The tooth module of the spur rack matches the tooth module of the gear.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: This high-current plug with a motorized unlocking mechanism utilizes a spur rack, gear, locking hole, and electronic locking pin. When the external motor is activated, the gear engages the spur rack, pushing the plug mechanism in a linear motion to connect or disconnect. Position sensors, such as Hall sensors, are integrated within the plug mechanism to monitor plug movement in real time and provide feedback to the motor control system for precise positioning. Once the plug mechanism is in place, an external electronic lock drives the electronic locking pin into the locking hole.

[0016] This high-current plug has a good safety locking mechanism and cannot be manually plugged in or out, with high reliability and good safety.

[0017] This design is suitable for scenarios with high current and high reliability requirements, such as electric vehicle charging piles, industrial robots, and power distribution cabinets.
