[0030] 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.

[0031] Example

[0032] like Figure 1-6 As shown, a sliding cover structure for a charger according to one embodiment of the present invention includes a sliding cover body 1, which is movably mounted on a charger body 2 via a slide rail mechanism 3.

[0033] The slide rail mechanism 3 includes a sliding cover metal sheet 31, a main body metal sheet 32, and a torsion spring 35 for connecting the sliding cover metal sheet 31 and the main body metal sheet 32.

[0034] like Figure 1-6 As shown, in some embodiments, the torsion spring 35 forms a spiral coil structure in the middle, and its two ends are respectively movably sleeved on the parallel sliding cover metal sheet 31 and the main body metal sheet 32, forming a sliding and torsion elastic connection mechanism.

[0035] The spiral structure provides radial elastic potential energy, and the two ends generate opposing torques during sliding, achieving a progressive damping effect for the opening and closing of the sliding cover. Figure 1As shown, when the sliding cover body 1 needs to be closed, the sliding cover body 1 slides relative to the charger body 2, and the sliding cover metal piece 31 moves relative to the main body metal piece 32. At the same time, the sliding cover metal piece 31 compresses the torsion spring 35 relative to the first limit pin 36 through the second limit pin 37, and at the same time generates progressive damping. When the second limit pin 37 moves to the side of the first limit pin 36, the torsion spring 35 is compressed to the extreme. At the same time, the two ends of the torsion spring 35 rotate on the second limit pin 37 and the first limit pin 36 to adjust the direction. When the second limit pin 37 passes the first limit pin 36, the torsion spring 35 immediately rebounds and opens the first limit pin 36 and the second limit pin 37, so that the sliding cover body 1 quickly closes the charger body 2 and maintains a stable closed state. Conversely, when the sliding cover body 1 needs to be opened from the closed state, the front part of the sliding cover body 1 slides to generate progressive damping, and the rear part moves quickly under the rebound of the torsion spring 35, so as to realize the rapid opening of the sliding cover body 1.

[0036] like Figure 2-5 As shown, in some embodiments, the sliding cover metal sheet 31 is fixedly disposed at the bottom of the sliding cover body 1, and the body metal sheet 32 ​​is fixedly disposed at the top of the charger body 2.

[0037] The main metal plate 32 is fixed to the top of the charger body 2 by several screws, ensuring the structural stability of the main metal plate 32.

[0038] like Figure 4-5 As shown, in some embodiments, both sides of the sliding cover metal sheet 31 are bent to form guide rail edges 34, and both sides of the main body metal sheet 32 ​​are bent to form guide rail grooves 33 that respectively engage with the two guide rail edges 34.

[0039] The guide rail edge 34 is formed by bending the two sides of the sliding cover metal sheet 31, and the guide rail groove 33 is formed by bending the two sides of the main body metal sheet 32. The integrated design ensures the overall structural strength and processing efficiency of the product.

[0040] like Figure 4-5 As shown, in some embodiments, the guide rail groove 33 is nested with a silent silicone strip 38.

[0041] The silent silicone strip 38 prevents the guide rail edge 34 from directly contacting the guide rail groove 33, avoiding rigid contact and making the sliding cover hardware 31 quieter when sliding.

[0042] like Figure 4-5 As shown, in some embodiments, the main body hardware sheet 32 ​​is provided with a limiting pin 36, the sliding cover hardware sheet 31 is provided with a limiting pin 37, and the two ends of the torsion spring 35 are respectively movably connected to the limiting pin 36 and the limiting pin 37.

[0043] The two ends of the torsion spring 35 are movably connected to the first limiting pin 36 and the second limiting pin 37 respectively, which will not affect the direction change of the torsion spring 35, and at the same time can stably hold the end of the torsion spring 35, ensuring the connection stability.

[0044] like Figure 2 As shown, in some embodiments, a fixing groove 11 is provided at the bottom center of the sliding cover body 1, and the sliding cover hardware 31 is fixedly installed inside the fixing groove 11 by screws.

[0045] The sliding cover hardware 31 is installed inside the fixing groove 11 by several screws, which ensures the stability of the sliding cover hardware 31. The design of the top of the sliding cover hardware 31 being embedded in the fixing groove 11 further reduces the gap between the sliding cover body 1 and the charger body 2, improving the overall appearance.

[0046] like Figure 1-3 As shown, in some embodiments, the bottom of the sliding cover body 1 is also provided with sliding grooves 12 located on both sides of the fixing groove 11, and the top of the charger body 2 is symmetrically provided with two limiting brackets 21. The tops of the two limiting brackets 21 are respectively slidably sleeved with the inside of the two sliding grooves 12. In some embodiments, the cross-section of the limiting brackets 21 and the sliding grooves 12 is T-shaped.

[0047] The cooperation between the limiting bracket 21 and the slide groove 12 further ensures the stability of the sliding cover body 1, and it will not sway or shake from side to side after opening, closing, or during sliding.

[0048] In summary, the sliding cover body 1 achieves stable sliding through the cooperation of the sliding cover hardware sheet 31 and the main body hardware sheet 32. The spiral structure of the torsion spring 35 generates a progressive damping effect during the sliding process, making the opening and closing action of the sliding cover body 1 both smooth and responsive. The integrated bending design of the guide rail edge 34 and the guide rail groove 33, combined with the silent silicone strip 38, effectively reduces sliding noise and enhances structural strength. The directional constraint of the limit pin 1 36 and limit pin 2 37 on the torsion spring 35 ensures the precise release of elastic potential energy. The nested structure of the T-shaped limit bracket 21 and the slide groove 12 further suppresses the shaking of the sliding cover body 1, ultimately achieving the technical effect of smooth and stable opening and closing of the sliding cover body 1, a firm and reliable closed state, and quiet operation.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
