Description

Technical Field

[0001] This utility model relates to the field of charging port cover technology, and specifically to a charging port cover locking structure. Background Technology

[0002] With the popularization of new energy vehicles, the design details related to vehicle charging have received increasing attention. Among them, the layout and locking structure of the slow charging port have become an important consideration for car manufacturers. Many mainstream new energy models choose to integrate the slow charging port into the front logo position. This design makes the vehicle appearance more concise and unified, while optimizing the convenience of operation during charging. The existing technology usually adopts a press-and-open spring locking structure. Pressing the logo triggers the internal spring mechanism to realize the automatic opening and locking of the slow charging port cover. However, this structure also has obvious shortcomings. It requires the integration of multiple precision components such as springs, trigger sensors, and locking buckles. The processing accuracy and assembly requirements are high, which leads to an increase in the overall manufacturing cost and thus increases the vehicle's price. To address these issues, we propose a charging port cover locking structure. Utility Model Content

[0003] The present invention aims to provide a charging port cover locking structure to solve the problem that the existing locking structures have high processing precision and assembly requirements, which leads to an increase in overall manufacturing costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a charging port cover locking structure, comprising a charging slot and a flip cover, the flip cover being hingedly installed in the charging slot, the locking structure being disposed between the charging slot and the flip cover, the locking structure comprising a locking tongue, a mounting base, a locking tongue rod, and a locking buckle, the locking tongue comprising an integrally formed fixed part and an elastic part, the elastic part being capable of elastic deformation, the fixed part being fixedly connected to the charging slot, the elastic part being configured as an "Ω" shape, and the two ends of the elastic part being configured as arcs, the mounting base being disposed on the inner wall of the flip cover, the locking buckle being disposed on the end of the mounting base near the locking tongue, the locking tongue rod being disposed on the end of the locking buckle near the flip cover, and the locking tongue rod being capable of engaging with the locking tongue.

[0005] The beneficial effects of this solution are as follows: When the "Ω"-shaped elastic part of the latch engages with the latch rod, it can form a stable locking force through elastic deformation to prevent the flip cover from being opened accidentally; at the same time, the arc-shaped end can reduce the frictional resistance during engagement, ensuring smooth locking and unlocking processes and adapting to the vibration environment during vehicle operation. The latch adopts an integrated fixed part and elastic part, reducing the number of parts. At the same time, the structure of components such as the latch and mounting base is simple, which is convenient for mass production and assembly. Compared with the traditional spring locking structure, it can significantly reduce manufacturing costs and assembly complexity, thereby reducing the overall manufacturing cost of the vehicle.

[0006] Preferably, as an improvement, the mounting base includes an integrally formed connecting part and several nut sleeves. The connecting part is located on the inner wall of the flip cover and is U-shaped. Several nut sleeves are evenly distributed between the connecting parts. Bolts are threaded into the nut sleeves. The latch is U-shaped and matches the connecting part. The latch has several through holes corresponding to the nut sleeves. The latch is fixedly connected to the nut sleeves by bolts.

[0007] The beneficial effects are as follows: The mounting base adopts an integrated U-shaped connecting part and nut sleeve, avoiding the splicing gap of the split structure, with stronger overall rigidity, and can withstand the locking force during locking and the vibration and impact during vehicle movement. The connecting part and the lock are both set as U-shaped, and are fastened with the threads of the bolt and the nut sleeve to form a stable connection with multiple points of uniform force, effectively preventing the lock from loosening or shifting. The lock can be directly aligned and installed through the mutual cooperation of the through hole and the bolt, without the need for complicated positioning and calibration, which greatly simplifies the assembly process and improves vehicle production efficiency.

[0008] Preferably, as an improvement, the middle of both ends of the latch is provided with an arc-shaped groove, and the two ends of the latch rod are fixedly connected to the arc-shaped groove respectively.

[0009] The beneficial effects are as follows: by fitting the outer wall of the locking tongue rod into the arc groove, the connection point between the locking tongue rod and the latch forms a curved surface contact. Compared with right angle or flat connection, this can disperse the impact force during locking and avoid component deformation or breakage caused by local stress concentration.

[0010] Preferably, as an improvement, the inner edge of the flip cover is provided with a rainproof frame that matches the inner wall of the charging slot.

[0011] The beneficial effects are as follows: the ring-shaped rain shield frame forms a close circumferential sealing structure with the inner wall of the charging slot, which can effectively prevent rainwater, car wash water or other liquids from seeping into the charging port from the gap between the flip cover and the charging slot, and avoid short circuits, corrosion and other failures caused by water ingress into the charging interface.

[0012] Preferably, as an improvement, the lower end of the charging slot is provided with a rotating groove, the lower end of the flip cover is provided with a hinge block, a rotating shaft is rotatably installed inside the hinge block, and the two ends of the rotating shaft are rotatably installed between the rotating groove.

[0013] The beneficial effects are as follows: by setting the hinge between the flip cover and the charging slot at the lower end, the flip cover can be flipped down to expose the charging slot, avoiding the fact that the rotating slot and hinge block are set at the upper end, which would cause rainwater to enter the charging slot through the gap between the rotating slot and the hinge block, thus preventing the charging interface from short-circuiting, corroding and other malfunctions due to water ingress.

[0014] Preferably, as an improvement, the outer wall of the hinge block is symmetrically provided with limiting blocks, which can abut against the rotating groove, and the limiting blocks are spherical.

[0015] Preferably, as an improvement, the upper outer wall of the flip cover is provided with a snap groove. Attached Figure Description

[0018] Example The basic implementation examples are as follows: Figures 1-4 As shown, Figure 1 The charging port cover locking structure shown includes a charging slot 1 and a flip cover 2, as shown. Figure 2 The charging slot 1 shown has a rotating slot 3 at its lower end, such as... Figure 3 The flip cover 2 shown has a hinge block 4 integrally formed at the lower end, and a rotating shaft 5 is rotatably mounted between the hinge blocks 4, as shown. Figure 1 The two ends of the rotating shaft 5 shown are rotatably mounted between the rotating grooves 3, as follows: Figure 3 The rainproof frame 6 shown is integrally formed on the inner edge of the flip cover 2 and matches the inner wall of the charging slot 1, as... Figure 4 The hinge block 4 shown is symmetrically fixedly mounted with limiting blocks 7 on its outer wall. The limiting blocks 7 are spherical and can abut against the rotating groove 3, thereby limiting the rotation angle of the flip cover 2 and preventing the flip cover 2 from colliding with the front of the vehicle when opened. Figure 3 and Figure 4 The flip cover 2 shown has a snap groove 8 integrally formed on the upper outer wall.

[0019] The locking structure is located between the charging slot 1 and the flip cover 2. The locking structure includes a latch 9, a mounting base 10, a latch rod 11, and a latch 12. Figure 2 The locking tongue 9 shown includes an integrally formed fixing part 13 and an elastic part 14. The elastic part 14 can undergo elastic deformation. The fixing part 13 is fixedly connected to the upper inner wall of the charging slot 1 by screws. The elastic part 14 is configured as an "Ω" shape, and both ends of the elastic part 14 are arc-shaped, such as... Figure 3 The mounting base 10 shown includes an integrally formed connecting part 15 and several nut sleeves 16. In this embodiment, there are three nut sleeves 16. The connecting part 15 is fixedly installed on the inner wall of the flip cover 2, and the connecting part 15 is U-shaped. Of course, the flip cover 2, the connecting part 15 and the nut sleeves 16 can all be produced using integral molding technology. Two nut sleeves 16 are located at both ends of the connecting part 15, and another nut sleeve 16 is located at the upper middle part of the connecting part 15. Each nut sleeve 16 is internally threaded with a bolt 17. The latch 12 is set as a U-shape that matches the connecting part 15, and the latch 12 has through holes corresponding to the nut sleeves 16. The latch 12 is fixedly connected to the nut sleeves 16 by bolts 17. The latch 12 is made of metal. Both ends of the latch 12 are provided with arc grooves 18. The two ends of the latch rod 11 are fixedly connected to the arc grooves 18 by welding, and the latch rod 11 can engage with the latch 9.

[0020] In use, the user flips the cover 2 downwards through the latch 8, causing the cover 2 to drive the locking tongue rod 11 out of the locking tongue 9. The two ends of the locking tongue 9 are reset by their own elasticity, so as to lock the cover 2 later. When the user needs to close the charging slot 1, the user rotates the cover 2 upwards and presses the cover 2 into the charging slot 1. During this process, the locking tongue rod 11 is pressed into the elastic part 14, thereby completing the fixation of the cover 2. In this solution, the locking tongue 9 adopts an integrally formed fixing part 13 and elastic part 14, which reduces the number of parts. At the same time, the structure of components such as the latch 12 and the mounting base 10 is simple, which is convenient for mass production and assembly. Compared with the traditional spring locking structure, it can significantly reduce manufacturing costs and assembly complexity, thereby reducing the overall manufacturing cost of the vehicle.
