Technical Field
[0001] This utility model relates to the field of automotive charging port technology, specifically to an automotive charging port locking structure and an automotive. Background Technology
[0002] With social development, new energy vehicles are being used more and more widely, among which electric vehicles are the most popular. Electric vehicles are equipped with rechargeable energy storage devices that provide power to the vehicle while it is in motion. When the energy storage device is low, it can be charged by plugging in an external charging gun through a charging port located on the vehicle body. The locking mechanism of the charging gun head engages with the locking groove of the charging port to secure the charging gun in place.
[0003] The existing utility model patent CN 109273885 A proposes a locking device for the charging port of an electric vehicle charging pile. This utility model automatically locks by connecting the pin to the socket, then locks again by the locking buckle slot, and finally completes the third layer of fixing by rotating the three-threaded quick-connect locking nut.
[0004] As described in the above technical solution, the charging gun is stably connected by using a pin, a locking buckle, and a three-pronged thread. However, this device has the problem of damaging the entire charging port when the charging gun is suddenly and violently removed or when it is impacted. When removing the charging gun, if there is a sudden violent removal or impact, the locking buckle will lock in the locking slot of the charging port, causing damage to the charging port. During maintenance, the staff can only replace the entire charging port to ensure its normal use, which greatly increases the maintenance cost. Utility Model Content

[0034] 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.
[0035] Please see Figure 1-5 The present application proposes a car charging port locking structure, which includes a mounting plate 1 and a guide ring 2.
[0036] like Figure 1-2 As shown, there is a mounting plate 1 and a guide ring 2. The mounting plate 1 is detachably mounted on the outer end face of the charging port. A through hole 101 is opened in the middle of the mounting plate 1 corresponding to the charging terminal. The guide ring 2 is located on the side of the mounting plate 1 away from the outer end face of the charging port and is detachably mounted on the mounting plate 1. A locking groove 201 is opened on the outer wall of the guide ring 2. The locking groove 201 is located near the end of the guide ring 2 away from the mounting plate 1. It is used to form a stress concentration weak area at the end of the guide ring 2, allowing it to break preferentially under abnormal external force.
[0037] Specifically, during vehicle assembly, the mounting plate 1 is detachably fixed to the outer end face of the charging port using bolts or clips. The through hole 101 is aligned with the charging terminal, which does not affect the insertion of the charging gun and facilitates later maintenance. When the charging gun is inserted, its locking hook engages with the locking groove 201 of the guide ring 2 to complete normal locking. If the gun is violently pulled out or subjected to a side impact, the stress concentration weak area formed by the locking groove 201 will break before the charging port body. The guide ring 2, as a low-cost and vulnerable part, is sacrificed, thereby protecting the more valuable charging port terminal and body panels from damage. Due to the detachable connection of the guide ring 2, the broken guide ring 2 can be replaced separately without disassembling the entire charging port, significantly reducing maintenance time and costs.
[0038] In some embodiments, such as Figure 1-2 As shown, a car charging port locking structure further includes an alarm component 3 and a trigger component 4. The alarm component 3 is disposed on the side of the mounting plate 1 facing the outer end face of the charging port. The trigger component 4 is slidably disposed on the inner side wall of the through hole 101 and located around the charging terminal. One end of the trigger component 4 facing the outer end face of the charging port extends to the alarm component 3 for triggering the alarm component 3. The end of the trigger component 4 facing the guide ring 2 is detachably connected to the guide ring 2.
[0039] Specifically, a trigger component 4 is added, which is detachably connected to the guide ring 2. When the guide ring 2 is displaced, it is driven to move closer to the alarm component 3, realizing an immediate alarm and reminding the operator to release the charging gun lock in time, avoiding improper operation such as forcibly pulling out the gun, and reducing the probability of damage.
[0040] In some embodiments, such as Figure 2-3 As shown, the triggering component 4 includes a sliding block 41, a transmission component 42, and a guide block 43. The sliding block 41 is disposed in the through hole 101, and the outer wall of the sliding block 41 is adapted to and slidably connected to the inner wall of the through hole 101. An avoidance hole 401 is provided in the middle of the sliding block 41 corresponding to the charging terminal. The guide ring 2 is detachably disposed on the end of the sliding block 41 away from the outer end face of the charging port and is located around the avoidance hole 401. The transmission component 42 is disposed on the end of the sliding block 41 facing the outer end face of the charging port and is movably connected to the mounting plate 1. The transmission component 42 corresponds to the alarm component 3 and is used to trigger the alarm component 3. Multiple guide blocks 43 are arranged in a circular array on the outer wall of the sliding block 41. Guide grooves 103 are provided on the inner wall of the through hole 101 corresponding to the multiple guide blocks 43.
[0041] Specifically, the sliding block 41 uses the through hole 101 as a track, forming a circumferential limit under the premise that the avoidance hole 401 does not interfere with the charging terminal. With the setting of the guide block 43 and the guide groove 103, it is ensured that the guide ring 2 can only slide in a straight line along the axial direction after being subjected to force, avoiding deflection and jamming. When an abnormal external force is transmitted to the guide ring 2 through the charging gun, the sliding block 41 moves outward synchronously, driving the transmission component 42 to move closer to the alarm component 3, triggering the alarm component 3 first. If the operator does not have time to react and the guide ring 2 breaks, it can be disassembled and reassembled independently, reducing maintenance workload and maintenance costs.
[0042] In some embodiments, such as Figure 4-5As shown, the transmission component 42 includes a transmission ring 421, a linkage rod 422, a limiting block 423, and a spring 424. The transmission ring 421 is fixedly disposed on the outer periphery of the end of the sliding block 41 and is used to trigger the alarm component 3. Multiple linkage rods 422 are detachably disposed on the side of the transmission ring 421 facing the mounting plate 1 and perpendicular to the transmission ring 421. The side of the linkage rods 422 facing the mounting plate 1 passes through the mounting plate 1 and is slidably connected to it. Multiple limiting blocks 423 are provided on the end of the corresponding linkage rod 422 facing the mounting plate 1. An active cavity 102 for limiting the sliding of the limiting block 423 is opened in the mounting plate 1. Multiple springs 424 are provided between the transmission ring 421 and the mounting plate 1 and are sleeved on the corresponding linkage rod 422.
[0043] Specifically, the transmission ring 421 and the sliding block 41 are integrally formed to create an annular force-bearing surface, which can convert the eccentric impact of the charging gun into a uniform axial thrust. Multiple linkage rods 422 pass through the mounting plate 1 and are slidably connected to it. They cooperate with the movable cavity 102 and the limiting block 423 at the end of the linkage rod 422. At the same time, a spring 424 for supporting reset is sleeved on the linkage rod 422 to stabilize the sliding block 41 in the through hole 101, ensuring normal insertion of the charging gun. Before removing the charging gun, the locking structure of the charging gun in the locking slot 201 is released, so that the charging gun can be removed smoothly. If the gun is forcibly pulled out or subjected to impact, the sliding block 41 drives the transmission ring 421 to move and compress the spring 424, and at the same time triggers the alarm component 3. After the charging gun is removed, the guide ring 2 is reset by the spring 424, which facilitates the insertion of the charging gun next time. At the same time, the linkage rod 422 is also a detachable connection. If it breaks, the corresponding linkage rod 422 can be replaced by removing the mounting plate 1, and the maintenance cost is extremely low.
[0044] In some embodiments, such as Figure 1-3 As shown, the alarm component 3 includes a buzzer 31 and a trigger button 32. The buzzer 31 is located on the side of the mounting plate 1 facing the outer end face of the charging port. The trigger button 32 is located on the side of the mounting plate 1 facing the outer end face of the charging port and is electrically connected to the buzzer 31. The trigger button 32 corresponds to the transmission ring 421 and is used to press the transmission ring 421 to trigger the buzzer 31. A placement groove 104 is provided on the side of the mounting plate 1 facing the outer end face of the charging port corresponding to the buzzer 31 for accommodating the buzzer 31. A sound-permeable hole 105 penetrating both sides of the mounting plate 1 is provided on the bottom wall of the placement groove 104 for effective sound transmission.
[0045] Specifically, when the charging gun is forcibly pulled out or subjected to impact, the movement of the sliding block 41 drives the movement of the transmission ring 421, which eventually abuts against the trigger button 32, thereby triggering the buzzer 31 to sound an alarm, reminding the operator to release the charging gun lock in time, avoiding improper operations such as forcibly pulling out the gun, and reducing the probability of damage; at the same time, a placement slot 104 is provided to accommodate the buzzer 31, forming a hidden setting, improving space utilization and the overall aesthetics of the vehicle.
[0046] This utility model also provides a car, including the above-mentioned car charging port locking structure, which is embedded in the charging port compartment of the vehicle body; under abnormal external force, the guide ring 2 breaks first to protect the charging port, and the buzzer 31 immediately alarms; during maintenance, only the guide ring 2 needs to be replaced, without removing the fender, reducing maintenance costs and improving user experience.
[0047] The specific workflow is as follows:
[0048] When the vehicle is in normal charging condition, the charging gun head is inserted into the charging port, and its locking hook slides along the front end of the guide ring 2 into the locking slot 201, completing the mechanical locking. At this time, the sliding block 41 is in the initial position under the pre-compression of the spring 424, and the buzzer 31 is silent. If an abnormal external force is applied to the charging gun due to misoperation, theft, or vehicle impact, the gun body first transmits the pulling force to the guide ring 2. The guide ring 2 drives the sliding block 41 to slide outward along the through hole 101. The displacement of the sliding block 41 instantly compresses the spring 424 and... Pushing the transmission ring 421 forward causes its outer edge to precisely press against the trigger button 32, immediately energizing the buzzer 31 to emit a continuous, sharp alarm, reminding the operator to stop. If the operator still does not release the button or does not have time to react, the pulling force causes the stress concentration weak area at the locking groove 201 to reach the fracture limit, and the guide ring 2 breaks at the predetermined position. At this point, the guide ring 2 can be directly replaced without disassembling the mounting plate 1 or the fender, and the entire system can be restored to full function, achieving dual protection of "alarm first, then sacrifice".
