[0026] Embodiment one

[0027] As Figures 2-3As shown, in this embodiment, each movable plate 420 has a protruding strip structure at one end and a groove at the other end. The protruding strip structure on each movable plate 420 is slidably engaged with the groove on the adjacent movable plate 420. The U-shaped plate 410 has a movable groove at one end and a protruding rod fixedly connected to the other end. The protruding rod is slidably engaged with the groove on the adjacent movable plate 420. The movable groove is slidably engaged with the protruding strip structure on the adjacent movable plate 420. The height of each movable plate 420 is greater than half the internal height of the U-shaped plate 410.

[0028] In this embodiment, the two adjacent movable plates 420 are in a state of mutual sliding engagement, and the movable plates 420 at both ends of any U-shaped plate 410 are respectively slidably engaged with the movable groove and the protrusion on the U-shaped plate 410, thereby making the movement of the multiple movable plates 420 more stable. Since the height of the movable plates 420 is greater than half of the internal height of the U-shaped plate 410, the movable plates 420 will never disengage from the sliding engagement state with the adjacent U-shaped plates 410 no matter how they are adjusted.

[0029] like Figure 2 and Figure 4 As shown, in this embodiment, the pressing mechanism 300 includes:

[0030] Multiple abutments 310 and multiple springs 320 are provided. Each abutment 310 corresponds to a multiple movable plate 420 within any U-shaped plate 410.

One end of each spring 320 is fixedly connected to the top surface of the corresponding abutment 310, and the other end is fixedly connected to the inner top surface of the cover 210. Each battery box 200 has multiple slots 203 on its inner bottom surface. Each slot 203 corresponds to a multiple abutment 310, and each slot 203 is located below the corresponding abutment 310.

[0031] In practice, since most power batteries are cylindrical, when the user puts the power battery into the battery box 200, the battery can be naturally locked in the adjacent slot 203 for initial positioning. Then, after the user puts the box cover 210 on the battery box 200, the positioning slots 311 on the multiple abutments 310 can naturally lock the adjacent batteries. Furthermore, the abutments 310 can press the battery against the bottom surface of the battery box 200 for fixation due to the reset force of the adjacent springs 320, thus preventing the battery from moving inside the battery box 200.

[0032] Example 2

[0033] Based on Embodiment 1, the card slot 201 and magnet 202 are provided to facilitate the fixing of the cover 210 to the battery box 200.

[0035] In specific implementation, in use, the box cover 210 is buckled to the battery box 200 by aligning the clamping strips 211 on the box cover 210 with the clamping grooves 201 on the battery box 200, so that the magnets 202 on the battery box 200 automatically attract the iron sheets 212 on the box cover 210 to fix the box cover 210, the magnets 202 can be selected from types with strong magnetism, such as rubidium magnets and the like, thereby achieving good fixing effect on the box cover 210, reducing the use of connecting members such as screws, avoiding the loss of the connecting members such as screws, and facilitating the disassembly by the user, in which the user only needs to pry open the box cover 210 by using a straight type screwdriver.

[0036] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0037] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can be properly combined to form other embodiments that can be understood by those skilled in the art.
