[0019] The present disclosure is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In one embodiment, if Figure 1 As shown, the protective cover assembly structure provided by the present invention includes a box body 1, an upper cover 2 and a protective cover 3, the box body 1 is an upper open structure, the upper cover 2 and the protective cover 3 are lower open structures, the upper cover 2 is arranged on the box body 1, and electrical components are arranged in the space enclosed by the upper cover 2 and the box body 1, and electrical components are also arranged in the space enclosed by the protective cover 3 and the box body 1.

[0021] The upper cover 2 and the protective cover 3 are located on the same side of the box body 1, and the upper cover 2 and the protective cover 3 are arranged in parallel. The box body 1 is provided with a first fixing structure, and the protective cover 3 is detachably connected to the box body 1 through the first fixing structure. The upper cover 2 is provided with a second fixing structure, and the protective cover 3 is detachably connected to the upper cover 2 through the second fixing structure. The protective cover 3 is connected to both the box body 1 and the upper cover 2. Compared with the existing protective cover assembly structure in which the protective cover is only connected to the box body, the protective cover 3 is less likely to fall off. Moreover, the protective cover 3 can also play a role in connecting the upper cover 2 and the box body 1, thereby strengthening the strength of the connection between the upper cover 2 and the box body 1.

[0022] See also Figures 2 to 3 In this embodiment, the first fixing structure includes a first fixing portion 11 provided on the box body 1. The first fixing portion 11 and the protective cover 3 are located on the same side of the box body 1. The first fixing portion 11 and the protective cover 3 are arranged in parallel. A clamping hole 111 is provided on the first fixing portion 11. A spring buckle 31 is provided on the protective cover 3 corresponding to the clamping hole 111. The spring buckle 31 cooperates with the clamping hole 111 to prevent the protective cover 3 from being separated from the box body 1.

[0023] The second fixing structure includes a second fixing portion 21 disposed on the upper cover 2, the second fixing portion 21 is located on the side of the upper cover 2 close to the protective cover 3, a groove 211 is disposed on the second fixing portion 21, the groove 211 faces the protective cover 3, and a convex strip 32 is disposed on the protective cover 3 corresponding to the groove 211, and the convex strip 32 is inserted into the groove 211 to prevent the protective cover 3 from being separated from the upper cover 2. The protective cover 3 is connected to the box body 1 by a snap-fit ​​structure, and the protective cover 3 is connected to the upper cover 2 by a plug-in method, so that the disassembly and assembly of the protective cover 3 are relatively convenient. In other embodiments, other detachable connection structures can also be used between the protective cover 3 and the box body 1 and the upper cover 2, for example, the protective cover 3 is connected to the box body 1 and the upper cover 2 by a snap-fit ​​structure.

[0024] In this embodiment, in order to take into account both structural simplicity and assembly stability, the number of first fixing parts 11 is two, and the protective cover 3 is located between the two first fixing parts 11. The number of second fixing parts 21 is two, and the protective cover 3 is located between the two second fixing parts 21. In other embodiments, the number of first fixing parts 11 and second fixing parts 21 can also be less or more, for example, the protective cover installation position next to the protective cover 3 for installing another smaller protective cover (this protective cover is not shown in the figure) has only one first fixing part and two second fixing parts.

[0025] In this embodiment, in order to facilitate pressing the spring buckle 31, a clearance groove 33 is provided on the protective cover 3 corresponding to the spring buckle 31, and the spring buckle 31 is located in the clearance groove 33. The spring buckle is a "+"-shaped structure, providing a sufficient contact area for the finger.

[0026] In this embodiment, the protrusion 32 includes an inserting portion 321 that cooperates with the groove 211 and a limiting portion 322 that cooperates with the second fixing portion 21. The inserting portion 321 is inserted in the groove 211, and the limiting portion 322 is located outside the groove 211 and abuts against the second fixing portion 21, so that the protective cover 3 can be assembled more stably.
