Description

Technical Field

[0001] This utility model relates to the field of power supply lock technology, and in particular to a power supply lock that is easy to adapt to electric vehicles. Background Technology

[0002] The power supply lock for electric vehicles is a special lock device designed for electric vehicle power systems. Its core function is to realize the connection and disconnection control and safety protection of electric vehicle power supplies, and it improves the adaptability to different electric vehicle power supply installation environments through structural optimization.

[0003] Currently, electric vehicle power supply locks are typically installed using screws. Screws create a rigid connection through the physical engagement of the threads, capable of withstanding significant vibrations and external impacts. This makes them particularly suitable for high-frequency vibration environments such as electric vehicles, preventing loosening due to bumps. The screw holes allow for precise positioning, ensuring the component remains fixed, making them suitable for scenarios requiring high assembly precision.

[0004] While screw-based fixing offers strong stability, repeated disassembly and reassembly can lead to stripped screw threads or component wear, affecting subsequent fixing effectiveness. Furthermore, if the screws rust or become stuck, disassembly becomes even more difficult and can damage the entire lock structure. Screw fixing relies on pre-set hole positions; if the hole dimensions and spacing at the electric vehicle's mounting location do not match the lock, direct installation is impossible, requiring additional modifications and lacking flexibility. Therefore, a power lock that is easily adaptable to electric vehicles is proposed to solve these problems. Utility Model Content

[0036] 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.

[0037] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The present invention provides an embodiment of a power supply lock that is easy to adapt to electric vehicles, including a protective shell 1, a sealing component at one end of the protective shell 1, and a shell 5 fixedly connected to both sides of the other end of the protective shell 1. A snap-fit ​​mounting component is provided inside the two shells 5, a bottom plate 7 is provided on the side of the protective shell 1, and a buffer component is provided inside the protective shell 1.

[0038] The snap-fit ​​mounting assembly includes a fixing plate 18, which is fixedly connected to the inner side of the middle of the housing 5 and also fixedly connected to the side of the protective shell 1. Two spring push rods 20 are fixedly connected to both sides of the fixing plate 18. Springs 19 are provided on the outer sides of each spring push rod 20, and locking blocks 15 are fixedly connected to the ends of each spring push rod 20. The snap-fit ​​mounting assembly also includes a connecting plate 16, which is fixedly connected to the side of the base plate 7. Locking groove rods 17 are fixedly connected to both ends of the connecting plate 16, and the locking blocks 15 are respectively locked into the inner sides of the two locking groove rods 17. The snap-fit ​​mounting assembly also includes two connecting plates 16, which are respectively fixedly connected to the inner sides of the ends of the locking blocks 15 and slidably connected to the inner side of the housing 5. When the power lock needs to be installed on the corresponding structure of the electric vehicle, the base plate 7 is pushed to move the connecting plate 16 towards the housing 5. The locking rods 17 at both ends of the connecting plate 16 gradually approach the inner side of the housing 5. Simultaneously, as the locking rods 17 move inwards towards the housing 5, the connecting plate 2 16 is pressed, causing the locking block 15 to retract inwards towards the housing 5, compressing the spring 19 and the spring push rod 20. When the locking rod 17 moves directly below the locking block 15, the connecting plate 2 16 is released, allowing the spring 19 to return to its original position, pushing the locking block 15 into the groove of the locking rod 17, thus completing the locking and fixing process.

[0039] Reference Figure 3 , Figure 6 and Figure 8 The sealing assembly includes two connecting blocks 22, which are fixedly connected to the outside of the protective shell 1. A connecting rod 21 is fixedly connected to the inside of each connecting block 22. Two connecting blocks 23 are rotatably connected to the outside of the connecting rod 21. A cover plate 2 is fixedly connected to the side of each connecting block 23, and the cover plate 2 is located inside the protective shell 1. Rotating the handle 3 pushes the cover plate 2 to rotate around the connecting rod 21, causing the cover plate 2 to cover the end opening of the protective shell 1. Two limiting arc blocks 4 are fixedly connected to the outside of the protective shell 1, respectively located on both sides of the cover plate 2. A handle 3 is fixedly connected to the outside of the cover plate 2. The limiting arc blocks 4 restrict the rotation angle of the cover plate 2, ensuring that the cover plate 2 fits tightly against the protective shell 1, forming a sealed space to prevent dust and moisture from entering the interior.

[0040] Reference Figure 3 and Figure 4 The buffer assembly includes multiple rubber sealing rings 13, all of which are disposed on the inner side of the protective shell 1. The power lock body 12 is located inside the protective shell 1, and the rubber sealing rings 13 are also disposed on the outer side of the power lock body 12. The multiple rubber sealing rings 13 on the inner side of the protective shell 1 tightly wrap around the power lock body 12, forming an elastic buffer layer. When the electric vehicle encounters bumps or vibrations during operation, the rubber sealing rings 13 absorb the impact force through their own deformation, reducing the hard collision between the power lock body 12 and the protective shell 1, and preventing damage to internal components.

[0041] Reference Figure 2 , Figure 4 and Figure 7 A fixing block 14 is fixedly connected to the end of the power lock body 12. The fixing block 14 is located inside the base plate 7, and multiple wires 9 are arranged inside the fixing block 14. Plugs 10 are fixedly connected to the ends of the multiple wires 9. When it is necessary to connect the electric vehicle's power supply, the plug 10 can be inserted into the electric vehicle's power interface or other compatible devices. Power or control signals are transmitted through the wires 9 to realize the power lock's control over the electric vehicle's power supply. A sealing ring 11 is provided inside the base plate 7 and is also located outside the fixing block 14. The sealing ring 11 on the inside of the base plate 7 fits tightly against the fixing block 14, preventing moisture and dust from entering from the connection between the wires 9 and the base plate 7, thus enhancing waterproof and dustproof performance. An insulating tube 8 is fixedly connected to the outside of the fixing block 14, and the insulating tube 8 is sleeved on the outside of the multiple wires 9. The insulating tube 8 on the outside of the fixing block 14 wraps around the wires 9, preventing exposed wires from causing short circuits or leakage, thus improving safety.

[0042] Working principle: When the power lock needs to be fixed to the electric vehicle, firstly, push the base plate 7 so that the slot rod 17 of the connecting plate 1 6 aligns with the locking block 15 inside the housing 5. Because the spring 19 pushes the spring push rod 20, the locking block 15 always maintains an outward elastic force. When the slot rod 17 is inserted into the housing 5, press the connecting plate 2 16 towards the center in advance, causing the locking block 15, along with the spring 19 and spring push rod 20, to move towards the center. When the slot rod 17 is fully in place, release the connecting plate 2 16 so that the locking block 15, under the action of the spring force, engages in the groove of the slot rod 17, achieving automatic locking. During disassembly, press the connecting plate 2 16 at the end of the locking block 15 to overcome the spring force, causing the locking block 15 to retract inward and disengage from the groove of the slot rod 17, allowing for quick disassembly of the lock.

[0043] By pulling the handle 3, the cover plate 2 rotates around the connecting rod 21, covering the opening at the end of the protective shell 1. At this time, the edge of the cover plate 2 is pressed and fitted against the inner side of the protective shell 1, forming a sealed space. When it is necessary to inspect the power lock 12 body, turn the handle 3 outward, and the cover plate 2 opens around the connecting rod 21, exposing the power lock 12 interface, which is convenient for inspection or replacement of the circuit.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
