Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging technology, specifically a retractable new energy vehicle charging interface. Background Technology

[0002] Automobiles are one of the most common means of transportation in modern life. They are generally composed of four basic parts: engine, chassis, body, and electrical equipment, and have the advantage of facilitating people's travel. In recent years, with the continuous advancement of technology, new energy vehicles have become increasingly popular. Common new energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] Pure electric vehicles are driven by electric energy. When the electric energy is depleted, it needs to be replenished in time. Existing cars are equipped with charging stations with several charging terminals. When charging, the charging gun is connected to the charging terminals, and the charging terminals transmit electrical energy to the controller. This electrical energy is then transmitted to the battery through the controller to charge the battery, thereby ensuring that the electric vehicle has a longer driving range.

[0004] A search revealed prior art publication number CN216085412U, which discloses a car charging dock that solves the problems of poor detection accuracy, easy failure, and inconvenient maintenance of temperature sensors in car charging docks. This car charging dock includes a main body for mounting several charging terminals, each detachably connected to the main body. The main body also houses several temperature sensors, the same number as the charging terminals, which can detect the temperature of each charging terminal during current transmission. This avoids malfunctions caused by excessive distance between the temperature sensors and the charging terminals, and also effectively prevents temperature sensors from easily failing due to being inserted too deeply into the charging terminals. This effectively ensures the detection accuracy of the temperature sensors while extending their service life. Furthermore, it allows for easy replacement of either the temperature sensor or the charging terminal if they fail during subsequent use, ensuring convenient maintenance.

[0005] However, existing technologies cannot simultaneously meet the dual requirements of "always being off the ground" and "automatic retraction and storage" of the charging gun cable, resulting in: the charging cable always dragging on the ground, easily getting tangled around pedestrians' feet or being run over by vehicles, causing safety hazards; in addition, the gun head and connector are still in contact with the ground when stored, allowing mud, sand and water to infiltrate, causing frequent insulation failures and a high failure rate.

[0006] Therefore, based on the above-mentioned search and combined with existing technologies, a scalable charging interface for new energy vehicles is proposed to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a retractable charging interface for new energy vehicles to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A retractable charging interface for new energy vehicles includes: a base, a support rod fixedly installed on the top surface of the base, a charging pile body fixedly installed on the side wall of the support rod, a spring telescopic section module provided on the bottom surface of the charging pile body, a rigid or semi-rigid straight section module connected to one side of the spring telescopic section module, and a charging gun body connected to the end of the rigid or semi-rigid straight section module; and a clamping assembly disposed on the charging pile body and used to clamp the rigid or semi-rigid straight section module.

[0010] Preferably, the clamping assembly includes: a connecting block, which is fixedly installed on the top surface of the charging pile body. The top surface of the connecting block has a moving groove, and the inner wall of the moving groove is rotatably connected to a threaded rod. The threaded rod is provided with two sections of threads with opposite directions of rotation. Each of the two sections of threads with opposite directions of rotation of the threaded rod is provided with a moving block. The top surfaces of the two moving blocks are fixedly installed with clamping rings, and the two clamping rings are arranged in a mirror image. The clamping assembly also includes a driving component.

[0011] Preferably, the driving component includes: a drive motor, which is fixedly mounted on the rear side wall of the connecting block, and the output shaft of the drive motor is connected to the rear side wall of the threaded rod. A sensor is provided on the top surface of the charging pile body on one side of the connecting block, and the sensor is used to detect whether the rigid or semi-rigid straight segment module is in the middle of the two clamping rings.

[0012] Preferably, the spring telescopic section module is composed of a fixed end connector, a helical spring cable body and a movable end connector connected in sequence. The fixed end connector has a waterproof rating of not less than IP67 and is fixed to the power signal output end inside the charging pile body. The straightened length of the helical spring cable body is equal to the length of the rigid or semi-rigid straight section module.

[0013] Preferably, the rigid or semi-rigid straight segment module includes: a pile end connector, wherein the pile end connector and the movable end connector are detachably connected;

[0014] Straight section skeleton tube: The straight section skeleton tube is made of carbon fiber tube or high-strength thin-walled aluminum alloy tube, with highly flexible wires arranged inside and covered with wear-resistant and weather-resistant sheath.

[0015] The vehicle-side connector is integrally formed with the charging gun body.

[0016] Preferably, the inner wall of the clamping ring 11 is provided with an elastic buffer pad for flexible contact with the outer wall of the rigid or semi-rigid straight segment module 5 to prevent scratches or noise during clamping.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes a segmented, equal-length design between the spring-loaded telescopic section at the pile end and the rigid straight section at the vehicle end. This ensures that the cable's critical parts remain at least 50cm off the ground throughout storage and use, completely eliminating the risks of the cable dragging on the ground, tripping, hooking onto vehicles, or being run over. The spring-loaded telescopic section automatically provides redundant length and retracts instantly, while the rigid straight section acts as a "lightweight, high-strength pole" to support the cable head. Users can insert and remove the cable at waist height without bending over, reducing operating force by more than 50% and significantly improving ease of use and safety. Attached Figure Description

A φ38mm cable outlet hole is opened at the bottom, and a nylon protective coil is embedded in the hole to prevent the wire from being cut. A spring telescopic section module 4 is provided on the bottom surface of the charging pile body 3. A rigid or semi-rigid straight section module 5 is connected to one side of the spring telescopic section module 4, and a charging gun body 6 is connected to the end of the rigid or semi-rigid straight section module 5.

[0026] A clamping assembly is mounted on the charging pile body 3 and is used to clamp the rigid or semi-rigid straight segment module 5.

[0027] The clamping assembly includes: a connecting block 7, which is fixedly installed on the top surface of the charging pile body 3. The top surface of the connecting block 7 is provided with a moving groove 8. The inner wall of the moving groove 8 is rotatably connected to a threaded rod 9. The threaded rod 9 is provided with two threads with opposite directions. Each of the two threads with opposite directions is provided with a moving block 10. The top surfaces of the two moving blocks 10 are fixedly installed with clamping rings 11. The two clamping rings 11 are arranged in a mirror image. The clamping assembly also includes a driving component.

[0028] The driving component includes a drive motor 12, which is fixedly mounted on the rear side wall of the connecting block 7. The output shaft of the drive motor 12 is connected to the rear side wall of the threaded rod 9. A sensor 13 is provided on the top surface of the charging pile body 3 on one side of the connecting block 7. The sensor 13 is used to detect whether the rigid or semi-rigid straight segment module 5 is between the two clamping rings 11.

[0029] The spring telescopic section module 4 is composed of a fixed end connector, a spiral spring cable body and a movable end connector connected in sequence. The fixed end connector has a waterproof rating of not less than IP67 and is fixed inside the power signal output end of the charging pile body 3.

[0034] Working principle:

[0035] In use, the user pulls the rigid or semi-rigid straight section module 5 from the clamp 11. After the sensor 13 detects the departure signal, the drive motor 12 reverses, causing the two clamps 11 to open. The user holds the straight section skeleton tube and walks towards the vehicle. If the parking distance is ≤L_r, the spring telescopic section module 4 remains in a natural spiral state, and the user directly inserts the charging gun body 6 into the vehicle. If the parking distance is >L_r, the user continues to pull, and the spiral spring cable body is stretched from L_min to L_s=1.2m, and the gun head is always kept ≥0.6m off the ground. After charging is completed, the user pulls out the gun and brings the straight section skeleton tube close to the connecting block 7. The sensor 13 is triggered again, and the drive motor 12 rotates forward, driving the threaded rod 9 to clamp the two clamps 11 to the straight section skeleton tube. At the same time, the spring telescopic section module 4 automatically retracts back to L_min, and the hook / buckle magnetically locks with the off-ground bracket mechanism 14, realizing one-click off-ground return.
