[0025] 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.
[0026] Reference Figure 1 - Figure 3This utility model provides an embodiment of a mobile power supply protection board with a snap-fit modular replacement structure, comprising a protection board body 1, a modular housing 2, and a transmission plate 3. The protection board body 1 is provided with a snap-fit mechanism 4 and an auxiliary mechanism 5. The snap-fit mechanism 4 includes a sliding plate 41, which is slidably connected to the top inner wall of the protection board body 1. An arc-shaped plate 42 is fixedly connected to the right outer wall of the sliding plate 41, and a compression spring 44 is fixedly connected to the left outer wall of the sliding plate 41. A groove 45 is opened and closed on the top outer wall of the protection board body 1. A trapezoidal groove 46 is opened on the rear inner wall of the modular housing 2. By setting the trapezoidal groove 46 and the trapezoidal plate 48 to cooperate with each other, the reverse installation of the protection board body 1 is prevented. A strip groove 47 is opened on the front inner wall of the modular housing 2. A trapezoidal plate 48 is fixedly connected to the rear outer wall of the protection board body 1, and a fixing plate 49 is fixedly connected to the front outer wall of the protection board body 1.
[0027] Reference Figure 2 - Figure 4 An arc-shaped plate 42 penetrates the outer right side wall of the protective plate body 1 and is snapped onto the inner right side wall of the modular housing 2. A concave-convex plate 43 is fixedly connected to the top outer wall of the sliding plate 41. The concave-convex plate 43 increases friction with the user's hand, facilitating movement and adjustment. A directional mark is provided on the top outer wall of the concave-convex plate 43. The concave-convex plate 43 is slidably connected to the top inner wall of the groove 45. The end of the compression spring 44 away from the sliding plate 41 is fixedly connected to the bottom inner wall of the protective plate body 1. The compression spring 44 generates a continuous thrust on the sliding plate 41. A trapezoidal plate 48 is slidably connected to the top inner wall of the trapezoidal groove 46. A fixed plate 49 is slidably connected to the top inner wall of the strip groove 47. The modular housing 2 is slidably connected to the outer side wall of the protective plate body 1. A transmission plate 3 is fixedly connected to the top inner wall of the protective plate body 1.
[0028] Reference Figure 3 - Figure 4The auxiliary mechanism 5 includes a slide 51, which is formed on the bottom inner wall of the modular housing 2. Inner groove frames 52 are slidably connected to the left and right inner walls of the slide 51. Inclined frames 53 are slidably connected to the left and right inner walls of the inner groove frames 52. By setting the inclined frames 53 and the inverted inclined frames 55 to cooperate with each other, the inclined frames 53 can move to compress the inverted inclined frames 55, or the inverted inclined frames 55 can move up and down to compress the inclined frames 53 to move back and forth. A spring damper 54 is fixedly connected to the left outer wall of the inclined frames 53. The spring damper 54 controls the movement of the inclined frames 53. The power is used for buffering and shock absorption. The top inner wall of the inner groove frame 52 is slidably connected to the inverted inclined frame 55. The top outer wall of the inverted inclined frame 55 is fixedly connected to the L-shaped clamping plate 56. There are four slide grooves 51. The four slide grooves 51 are respectively opened on the bottom inner wall of the protective plate body 1 and the modular shell 2. The inverted inclined frame 55 is slidably connected to the right outer wall of the inclined frame 53. The bottom outer wall of the inverted inclined frame 55 is fixedly connected to the wear-resistant pad. The end of the spring damper 54 away from the inclined frame 53 is fixedly connected to the left inner wall of the slide groove 51. The top outer wall of the L-shaped clamping plate 56 is fixedly connected to the silicone pad.
[0029] Working principle: When assembly is required, the power bank is placed on the L-shaped clamp 56 for clamping. Then, the trapezoidal plate 48 on the main body of the protective plate 1 is aligned with the trapezoidal groove 46. The main body of the protective plate 1 is then pressed to make the arc plate 42 snap into the inner wall of the modular housing 2. The internal power bank is then pressed to the appropriate size for locking and fixing. When disassembly is required, the sliding plate 41 is moved by pulling the concave-convex plate 43. The movement of the sliding plate 41 moves the arc plate 42, separating the arc plate 42 from the modular housing 2. Then, the main body of the protective plate 1 is lifted to separate from the modular housing 2, allowing for convenient access to the internal power components. When the modular housing 2 of the power bank falls to the ground or is impacted by external forces, the L-shaped clamp 56 moves laterally as the internal power bank shakes. The lateral movement of the L-shaped clamp 56 drives the inclined frame 55 to move. The inclined frame 55 moves and presses the inclined plane frame 53 to move. The inclined plane frame 53 moves and presses the spring damper 54 to provide left and right buffering and shock absorption. At the same time, when the internal power bank shakes up and down, it drives the L-shaped clamp 56 to move up and down. The movement of the L-shaped clamp 56 drives the inclined frame 55 to move. The inclined frame 55 moves and presses the inclined plane frame 53 to move. The inclined plane frame 53 moves and presses the spring damper 54 to provide up and down shaking and shock absorption.
[0030] 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.
