[0045] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0046] Figure 1-Figure 5 FIG. 1 shows a structural diagram of a chassis 100 according to an embodiment of the present application. Figure 1-Figure 5 As shown, the chassis 100 may include:

[0047] Housing 110;

[0048] At least two connecting members 120, at least two connecting members 120 are disposed on the housing 110;

[0049] A cover 130, which is detachably connected to the housing 110, and has a groove 131 corresponding to the connector 120;

[0050] A convex strip 132, the convex strip 132 is installed on the cover body 130, and the convex strip 132 is located in the groove 131;

[0051] When the cover 130 is installed on the housing 110 , the connecting member 120 is located in the groove 131 , and the convex strip 132 is in contact with the connecting member 120 .

[0052] In this embodiment, a connecting groove 121 corresponding to the shape of the convex strip 132 is provided on the connecting member 120, and the shell 110 and the cover body 130 are detachably connected. When the cover body 130 needs to be installed on the shell 110, the connecting member 120 is placed in the corresponding groove 131, and the cover body 130 is pushed to make the connecting member 120 slide in the groove 131, and the convex strip 132 is slidably connected to the connecting groove 121, so that the convex strip 132 and the connecting member 120 are limited, and the cover body 130 and the shell 110 are quickly installed. When the cover body 130 needs to be disassembled, the connecting member 120 only needs to be slid in the opposite direction to separate from the convex strip 132, and the connecting member 120 can be taken out from the groove 131, and the cover body 130 can be disassembled;

[0053] Furthermore, the length of the convex strip 132 is less than the length of the connecting member 120, and the sum of the lengths of the convex strip 132 and the connecting member 120 is less than the length of the groove 131. When the connecting member 120 is placed in the groove 131, it is ensured that there is enough space in the groove 131 for the connecting member 120 to enter. At this time, the connecting member 120 and the convex strip 132 are not in contact. When the cover 130 is pushed to move, the connecting member 120 moves in the groove 131, and the convex strip 132 gradually slides into the connecting groove 121. When one end of the connecting member 120 abuts against one end of the groove 131, the sliding stops, and at this time, the convex strip 132 is completely immersed in the connecting groove 121.

[0054] A groove 131 is provided on the cover 130, a convex strip 132 is installed in the groove 131, and a connector 120 is installed on the housing 110. The connector 120 slides in the groove 131 and is slidably connected with the convex strip 132, so that the cover 130 and the housing 110 can be quickly installed, and the use of screws during the installation of the cover 130 is reduced, so that the number of screw holes on the surface of the cover 130 is reduced, and the installation and disassembly are facilitated while ensuring the aesthetics;

[0055] It should be noted that the connecting member 120 is a rectangular block with an arc end at one end, and the cross-sectional view of the convex strip 132 is polygonal, and a triangular structure is adopted in this solution.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, it also includes:

[0057] A limiting member 111, which is detachably mounted on the housing 110;

[0058] When the cover 130 is installed on the housing 110 , the limiting member 111 is in contact with the cover 130 .

[0059] In this embodiment, after the cover body 130 and the shell 110 are installed, the limit member 111 is installed on the shell 110 by screws. When the limit member 111 is installed on the cover body 130, a part of the limit member 111 blocks the cover body 130, so that the cover body 130 cannot slide along the surface of the shell 110. At the same time, the convex strip 132 ensures that the cover body 130 cannot be opened by lifting upward, thereby limiting the cover body 130 and ensuring the stability of the cover body 130 after being connected to the shell 110.

[0060] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, it also includes:

[0061] When the cover 130 is mounted on the housing 110 , the stopper 111 is flush with the surfaces of the cover 130 and the housing 110 .

[0062] In this embodiment, a first recessed portion 112 is formed on the shell 110, and a second recessed portion 133 is formed on the cover body 130. When the cover body 130 is installed on the shell 110, the first recessed portion 112 is connected to the second recessed portion 133, and part of the limiting member 111 is located in the first recessed portion 112, and the other part is located in the second recessed portion 133.

[0063] When the cover 130 is installed on the housing 110, the limiting member 111 is installed on the housing 110 by screws. At this time, a part of the limiting member 111 is located in the first groove 131, and the other part is located in the second groove 131, so as to limit the cover 130 in the horizontal direction.

[0064] Furthermore, the thickness of the limiter 111 is consistent with the depth of the first groove 131 and the second groove 131 , ensuring that the limiter 111 is flush with the surface of the shell 110 and the cover 130 after installation, thereby ensuring the aesthetics of the limiter 111 after installation.

[0065] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment,

[0066] The housing 110 includes:

[0067] Bottom plate 113;

[0068] Two first side walls 114, the two first side walls 114 are parallelly mounted on the bottom plate 113, and at least two connecting members 120 are evenly mounted on the corresponding first side walls 114;

[0069] The second side wall 115 is installed on the bottom plate 113, and the two ends of the second side wall 115 are respectively connected to one end of the two first side walls 114, the stopper 120 is detachably connected to the second side wall 115, and the first recessed portion 112 is located on the second side wall 115;

[0070] The third side wall 116 is installed on the bottom plate 113 . Both ends of the third side wall 116 are respectively connected to one end of the two first side walls 114 away from the second side wall 115 . The second side wall 115 and the third side wall 116 are arranged in parallel.

[0071] In this embodiment, at least one connecting member 120 is connected to each first side wall 114 to ensure that when the cover body 130 is connected to the housing 110, one side of the cover body 130 will not be lifted. The two first side walls 114 are arranged in parallel, the third side wall 116 is arranged in parallel with the second side wall 115, and the two first side walls 114 are vertically connected to the corresponding third side wall 116 and the second side wall 115, so that the cross section of the housing 110 forms a rectangular structure. The first recessed portion 112 is located on the second side wall 115 and corresponds to the third side wall 116.

[0072] Further, the height of the third side wall 116 is greater than the two first side walls 114 and the second side wall 115; the height of the first side wall 114 is the same as that of the second side wall 115. When the connecting member 120 enters the groove 131 and starts to slide, the cover body 130 slides along the first side wall 114 and the top of the second side wall 115. When one end of the connecting member 120 contacts one end of the groove 131, one end of the cover body 130 contacts the third side wall 116. The third side wall 116 performs secondary position limiting on the cover body 130. At the same time, after the third side wall 116 contacts the cover body 130, the top surface of the third side wall 116 is flush with the surface of the cover body 130, thereby ensuring the aesthetics of the cover body 130 after connection. The first recessed portion 112 is provided on the second side wall 115, and the second side wall 115 corresponds to the side of the cover body 130 having the second recessed portion 133.

[0073] Furthermore, a connector 134 is provided on one end of the cover body 130 away from the second recessed portion 133, and a slot 1161 adapted to the connector 134 is opened on the third side wall 116. The connector 134 is fixedly set on the cover body 130. When the cover body 130 contacts the third side wall 116, the connector 134 enters the slot 1161, and the connector 134 is plugged into the slot 1161, and the connecting groove 121 and the convex strip 132 are used to limit the upward movement path of the cover body 130 relative to the shell 110, thereby ensuring the stability of the cover body 130 installed on the shell 110.

[0074] like Figure 3 As shown, in one embodiment,

[0075] The groove 131 faces the housing 110 , and the protruding strip 132 is spaced apart from the top of the groove 131 .

[0076] In this embodiment, a certain interval is set between the ridge 132 and the top of the groove 131. When the ridge 132 is slidably connected with the connecting groove 121, it is ensured that the ridge 132 will not fall out of the connecting groove 121 in the upward direction, thereby ensuring the stability of the installation of the cover body 130.

[0077] The embodiment of the present application further provides a sound box, comprising a chassis 100 as described in any one of the above items.

[0078] In this embodiment, the chassis 100 is not only applicable to a speaker box, but also applicable to a computer chassis, a television chassis, etc.
