The box cover 12 is rotatably connected to the left side wall 18 (i.e., the connecting wall 18a) through the rotating shaft assembly 13 to open or close the internal space Q1.

[0101] Among them, the connecting wall 18a includes an inner bracket 19 and an outer panel 20. The inner bracket 19 is mainly used to provide a supporting force, and the outer panel 20 covers the outside of the inner bracket 19 and can play a decorative role.

[0102] The inner bracket 19 has a mounting end face P1 facing the box cover 12. The outer panel 20 includes a side panel 21 and a folded edge 22; the side panel 21 is located outside the inner bracket 19, and the folded edge 22 is bent from the side panel 21 and extends to a position corresponding to covering the mounting end face P1.

[0103] The following Figures 6-8 exemplarily introduces the box cover 12 in this embodiment.

[0104] See Figures 6-8 , in this embodiment, the box cover 12 includes a front frame 23, a mirror 24 and a rear cover plate 25, and the mirror 24 is clamped and fixed between the front frame 23 and the rear cover plate 25. The middle position of the front frame 23 is a through hole K1 for allowing the mirror surface of the mirror 24 to be exposed, which is convenient for the user to look in the mirror.

[0105] Among them, the rear cover plate 25 has opposite first and second side edges 26 and 27, and the first side edge 26 is used to connect the rotating shaft assembly 13. Optionally, an inwardly concave inner groove C2 is formed on one surface of the rear cover plate 25 facing the front frame 23 near the first side edge 26. The inner groove C2 is used to accommodate and shield a part of the structure of the rotating shaft assembly 13 (such as the connecting plate 33 introduced below) to reduce the exposure of the rotating shaft assembly 13. Optionally, the inner groove C2 extends to the first side edge 26, and the rear cover plate 25 is provided with a notch K2 that penetrates the rear cover plate 25 from the bottom surface of the inner groove C2. The notch K2 is used to allow a part of the structure of the rotating shaft assembly 13 (such as the arc-shaped sliding tongue 32 introduced below) to pass through the rear cover plate 25.

[0106] Figure 4 Or Figure 7 Among the three rotating shaft assemblies 13 shown, part is the first rotating shaft assembly 13a and part is the second rotating shaft assembly 13b. For example, Figure 4 Or Figure 7 In [description], the uppermost rotating shaft assembly 13 is the first rotating shaft assembly 13a, and the two rotating shaft assemblies 13 located below are the second rotating shaft assemblies 13b.

[0107] Of course, in other embodiments, all three rotating shaft assemblies 13 may adopt the first rotating shaft assembly 13a or the second rotating shaft assembly 13b, which is not limited herein.

[0108] Next, in conjunction with Figure 9 And Figure 10 Exemplarily introduce the first rotating shaft assembly 13a of this embodiment.

[0109] Refer to Figure 9 And Figure 10 In this embodiment, the first rotating shaft assembly 13a includes a fixed part 28 and a sliding part 29.

[0110] Among them, the fixed part 28 is used to fixedly connect the box body 11, and the fixed part 28 defines an arc-shaped sliding groove C3. For example, the fixed part 28 includes a fixed seat 30 and a groove block 31. The fixed seat 30 is used to fixedly connect the box body 11, and the groove block 31 is fixedly connected to the fixed seat 30. The arc-shaped sliding groove C3 is located between the fixed seat 30 and the groove block 31. The sliding part 29 includes an arc-shaped sliding tongue 32 and a connecting plate 33. The arc-shaped sliding tongue 32 is slidably engaged with the arc-shaped sliding groove C3 so that the sliding part 29 rotates relative to the fixed part 28 around the central axis of the arc-shaped sliding groove C3. The connecting plate 33 is connected to the arc-shaped sliding tongue 32 and is used to fixedly connect the box cover 12. In this way, the rotational connection between the box cover 12 and the box body 11 can be realized.

[0111] In the first rotating shaft assembly 13a, the split design of the fixed seat 30 and the groove block 31 enables, when assembling the first rotating shaft assembly 13a, the arc-shaped sliding tongue 32 of the sliding part 29 to be first snapped into the arc-shaped sliding groove C3 of the groove block 31 to complete the assembly of the sliding part 29 and the groove block 31, and then the combination of the sliding part 29 and the groove block 31 is fitted to the fixed seat 30 to fix the groove block 31 to the fixed seat 30, thus completing the assembly of the first rotating shaft assembly 13a. The assembly is convenient, and the processing of details such as the arc-shaped sliding groove C3 is convenient.

[0112] Referring to Figure 11 , in the first rotating shaft assembly 13a, the fixing part 28 includes an intermediate part 34 and two connecting edges 35, and the two connecting edges 35 are respectively connected to both sides of the intermediate part 34; the arc-shaped sliding groove C3 is located at the intermediate part 34.

Optionally, the installation end face P1 is further recessed with two side grooves C5 located on both sides of the intermediate groove C4, and the two side grooves C5 are used to respectively receive the two connecting edges 35. In this way, the first rotating shaft assembly 13a can make full use of the space recessed in the inner bracket 19, which is beneficial to making the distance between the lid 12 and the box body 11 smaller, thereby reducing the exposure of the internal structure of the first rotating shaft assembly 13a and the box body 11.

[0113] Optionally, a channel groove C6 is formed on the arc-shaped sliding tongue 32 for allowing a wire 38 to pass through to achieve electrical connection between the electronic components (such as a power supply) on the box body 11 and the electronic components (such as an LED lamp) on the lid 12.

[0114] Next, with reference to Figures 12-15 the second rotating shaft assembly 13b of this embodiment will be exemplarily introduced.

[0115] Referring to Figures 12-15 , in this embodiment, on the basis of the first rotating shaft assembly 13a, the second rotating shaft assembly 13b further includes a connecting rod 39, a first shaft member 40 and a second shaft member 41. That is, the second rotating shaft assembly 13b includes a fixing part 28, a sliding part 29, a connecting rod 39, a first shaft member 40 and a second shaft member 41.

[0116] Among them, the fixed seat 30 is further provided with a sliding groove C7. One end of the connecting rod 39 is rotatably connected to the end of the arc-shaped sliding tongue 32 away from the connecting plate 33 through the first shaft member 40.
