[0030] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 to 4 As shown, an embodiment of the present utility model provides a housing assembly 10, which includes a first housing 100, a second housing 200 and a connection structure 300; the second housing 200 is detachably connected to the first housing 100; the connection structure 300 includes a plug-in part 310, a fixing part 320 and a limiting part 330. The plug-in part 310 is connected to the first housing 100 and is located inside the first housing 100. The fixing part 320 is connected to the second housing 200 and protrudes towards the outside of the second housing 200, and the fixing part 320 is provided with a fixing groove 3211. The plug-in part 310 is in plug-in fit with the fixing groove 3211. The limiting part 330 is connected to the second housing 200. Wherein, the opening direction of the fixing groove 3211 is perpendicular to the direction of the first housing 100 facing the second housing 200. When the plug-in part 310 is in plug-in fit with the fixing groove 3211, the limiting part 330 is used to fix the first housing 100 and the second housing 200.

[0032] When assembling the housing assembly 10 of this embodiment, first, align and fit the first housing 100 with the second housing 200, and place the fixing member 320 inside the first housing 100 and the plug-in member 310 on the opening side of the fixing groove 3211. Then, drive the first housing 100 to move forward relative to the second housing 200 until the plug-in member 310 and the fixing groove 3211 are snap-fitted. In this way, the movement of the first housing 100 in the direction away from the second housing 200 can be limited. At this time, the limiting member 330 can abut against the first housing 100 to limit the movement of the first housing 100 in the reverse direction. Through the cooperation of the limiting member 330 and the plug-in member 310, the first housing 100 and the second housing 200 can be fixed. When it is necessary to separate the first housing 100 and the second housing 200, only need to deflect the limiting member 330 away from the first housing 100 to release the first housing 100.

[0033] In the housing assembly 10 of this embodiment, by providing a connection structure 300 between the first housing 100 and the second, the convenient disassembly and assembly function of the two can be realized, without additional components, and the connection reliability is high.

[0034] Furthermore, a first guiding surface 3111 is provided at the end of the plug-in member 310. When the plug-in member 310 is connected to the fixing groove 3211, the first guiding surface 3111 is used to drive the plug-in member 310 to move into the fixing groove 3211.

[0035] In this embodiment, by providing a first guiding surface 3111 at the end of the plug-in member 310, the first guiding surface 3111 is inclined in the installation direction of the first housing 100 away from the second housing 200. As Figure 4 shown in the embodiment, the first housing 100 is in fit with the second housing 200. At this time, the installation direction of the first housing 100 is flush with the length direction of the first housing 100, or it can also be described as that the installation direction of the first housing 100 is flush with the mating surface of the first housing 100 and the second housing 200. When the first housing 100 is connected to the second housing 200, when the first guiding surface 3111 contacts the fixing member 320, the installation of the plug-in member 310 can be guided through the sliding between the two, so that the plug-in member 310 can enter the fixing groove 3211 of the fixing member 320 more smoothly to complete the connection between the two. The structure is simple and the assembly convenience is improved.

[0036] In one embodiment, the plug-in member 310 includes a plug-in portion 311 and a first reinforcing portion 312. The plug-in portion 311 is connected to the first housing 100, and the first reinforcing portion 312 is respectively connected to the plug-in portion 311 and the inner wall of the first housing 100. The plug-in portion 311 is used for plug-in fit with the fixing groove 3211, and the first guiding surface 3111 is provided at the end of the plug-in portion 311.

[0037] With this arrangement, by connecting the first reinforcing portion 312 and the plugging portion 311, the connection strength between the first housing 100 and the plug-in member 310 can be effectively improved. At the same time, when the first housing 100 is manufactured by an injection molding process, it is also convenient for demolding at the plug-in member 310.

[0038] Furthermore, the fixing member 320 is provided with a second guiding surface 3212, and the second guiding surface 3212 is arranged at the opening of the fixing groove 3211. When the plug-in member 310 is connected to the fixing groove 3211, the second guiding surface 3212 is used to drive the plug-in member 310 to move towards the inside of the fixing groove 3211.

[0039] In this embodiment, by arranging the second guiding surface 3212 at the end of the fixing groove 3211, the second guiding surface 3212 is inclined in a direction away from the second housing 200 along the installation direction of the first housing 100. As Figure 4 shown in the embodiment, the first housing 100 and the second housing 200 are fitted together. At this time, the installation direction of the first housing 100 is flush with the length direction of the first housing 100, or it can also be described as that the installation direction of the first housing 100 is flush with the fitting surface of the first housing 100 and the second housing 200. When the first housing 100 is connected to the second housing 200, when the second guiding surface 3212 contacts the plug-in member 310, the installation of the plug-in member 310 and the fixing member 320 can be guided through the sliding between the two, so that the plug-in member 310 can enter the fixing groove 3211 more smoothly to complete the connection between the two. The structure is simple and the assembly convenience is improved.

[0040] Specifically, the fixing member 320 includes a fixing portion 321 and a second reinforcing portion 322. The fixing portion 321 is connected to the second housing 200 and extends towards the outside of the second housing 200, and the second reinforcing portion 322 is respectively connected to the second housing 200 and the fixing portion 321.

[0041] With this arrangement, by connecting the second reinforcing portion 322 and the fixing portion 321, the connection strength between the second housing 200 and the fixing member 320 can be effectively improved. At the same time, when the second housing 200 is manufactured by an injection molding process, it is also convenient for demolding at the fixing member 320.

[0042] Furthermore, one end of the limiting member 330 away from the fixing member 320 is provided with a third guiding surface 3311. When the first housing 100 is connected to the second housing 200, the third guiding surface 3311 is used to contact the first housing 100 and drive the limiting member 330 to move in a direction away from the first housing 100, and the limiting member 330 can be snap-fitted with the first housing 100 under the elastic action.

[0043] Refer to Figure 4As shown in the installation schematic diagram, after the first housing 100 is attached to the second housing 200, during the process of driving the first housing 100 to move relative to the second housing 200 along the installation direction of the first housing 100, since the limiting member 330 protrudes toward the first housing 100, the end of the limiting member 330 will first contact the edge of the first housing 100. At this time, by the cooperation of the third guiding surface 3311 provided and the first housing 100, the limiting member 330 can be driven to bend away from the first housing 100 to complete the avoidance. After the first housing 100 and the second housing 200 are installed in place, the limiting member 330 is reset under its own elastic force and is clamped to the end of the first housing 100, thereby limiting the movement of the first housing 100 relative to the second housing 200 in the installation direction. The plug-in member 310 and the fixing member 320 are plugged in to limit the movement of the first housing 100 relative to the second housing 200 along the direction perpendicular to the installation direction, and thus the first housing 100 and the second housing 200 can be fixed; by providing the third guiding surface 3311 on the limiting member 330, the assembly convenience between the first housing 100 and the second housing 200 can be improved.

[0044] Specifically, the limiting member 330 includes a limiting portion 331 and a connecting portion 332. The limiting portion 331 protrudes from the second housing 200 toward the first housing 100. The connecting portion 332 is an elastic structure and is respectively connected to the second housing 200 and the limiting portion 331. The third guiding surface 3311 is provided on the side of the limiting portion 331 away from the connecting portion 332.

[0045] With this setting, when the first housing 100 is connected to the second housing 200, the connecting portion 332 can bend and deform so that the limiting portion 331 avoids the first housing 100, and after the first housing 100 and the second housing 200 are installed in place, the connecting portion 332 drives the limiting portion 331 to reset to fix the first housing 100 and the second housing 200.

[0046] In an embodiment, the second housing 200 is provided with an avoidance groove 210. The connecting portion 332 is arranged at the opening of the avoidance groove 210. When the limiting member 330 contacts the first housing 100, the connecting portion 332 can bend at least partially into the avoidance groove 210.

[0047] It can be understood that by providing the avoidance groove 210 on the second housing 200 to cooperate with the connecting portion 332, the deformation of the connecting portion 332 can be avoided, and at the same time, the internal stress at the connection between the connecting portion 332 and the second housing 200 can be reduced to improve the durability of the connecting portion 332.

[0048] Furthermore, the number of connection structures 300 is multiple groups, and the multiple groups of connection structures 300 are arranged at intervals along the moving direction of the first housing 100 relative to the second housing 200.

[0049] In this embodiment, by providing multiple groups of connection structures 300 to connect the first housing 100 and the second housing 200, not only can the connection strength between the first housing 100 and the second housing 200 be improved, but also the assembly accuracy between the two can be improved during the connection process of the first housing 100 and the second housing 200.

[0050] Refer to Figure 4 As shown, the assembly process of the housing assembly 10 is as follows:

[0051] First, move the second housing 200 towards the first housing 100 and misalign the plug-in member 310 and the fixing member 320;

[0052] After that, fit the first housing 100 and the second housing 200 together and make the opening direction of the plug-in member 310 correspond to the fixing groove 3211;

[0053] Drive the second housing 200 to move relative to the first housing 100 along the installation direction of the housing assembly 10 (certainly, at this time, the first housing 100 can also be driven to move relative to the second housing 200, which is not uniquely limited here), until the plug-in member 310 is buckled with the fixing member 320. During this process, the limiting member 330 can also abut against the end of the first housing 100.

[0054] In this way, the first housing 100 and the second housing 200 can be connected and fixed, and the assembly is convenient. At the same time, since the plug-in member 310 is arranged inside the first housing 100 and the fixing member 320 is arranged outside the second housing 200, when the first housing 100 and the second housing 200 are combined, the outer surfaces of the two can be flush, and the combined structure of the two is compact.
