After the first positioning portion 12 is limitedly matched with the second positioning portion 31, the panel 30 is installed on the first housing 10 and the second housing 20 by clamping the third clamping portion 32 with the first clamping portion 11, and the fourth clamping portion 33 with the second clamping portion 21.

[0046] By applying the technical solution of this embodiment, after the first positioning portion 12 and the second positioning portion 31 are limitedly matched, the panel 30 is installed on the first shell 10 and the second shell 20 by snapping together the third snapping portion 32 and the first snapping portion 11 and the fourth snapping portion 33 and the second snapping portion 21.

[0047] Compared with the single constraint orientation of the panel in the prior art, the third clamping portion 32 and the fourth clamping portion 33 of the panel 30 in this embodiment are respectively located on both sides of the second positioning portion 31, so that the first shell 10 and the second shell 20 are matched with the panel 30 in multiple directions, thereby improving the assembly stability between the panel 30 and the first shell 10 and the second shell 20, and solving the problem in the prior art that the installation method of the control panel affects its assembly stability.

[0048] like Fig.12 As shown, the housing assembly further includes a fastener 40. The fastener 40 is disposed inside the first housing 10 and the second housing 20 to connect the first housing 10 and the second housing 20.

[0049] Optionally, the fastener 40 is a screw or a bolt.

[0050] Optionally, there is one fastener 40; or, there are multiple fasteners 40, and the multiple fasteners 40 are arranged at intervals along the height direction and / or width direction of the first shell 10; or, the multiple fasteners 40 are arranged at intervals along the height direction and / or circumferential direction of the first shell 10. In this way, the above arrangement makes the number selection and arrangement of the fasteners 40 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0051] In this embodiment, there are multiple fasteners 40 , and the multiple fasteners 40 are arranged at intervals along the height direction and / or circumferential direction of the first shell 10 , thereby improving the assembly stability of the first shell 10 and the second shell 20 .

[0052] like Figure 2 As shown, one of the first positioning portion 12 and the second positioning portion 31 is a convex column, and the other of the first positioning portion 12 and the second positioning portion 31 is a concave portion. The convex column extends into the concave portion and cooperates with the concave portion to achieve positioning between the panel 30 and the first shell 10. In this way, the above positioning method is simple and reliable, which can ensure the accurate position of the panel 30 on the first shell 10 and the second shell 20, avoid the shaking of the panel 30 during use, and improve the user experience. At the same time, the above setting makes the structural selection of the first positioning portion 12 and the second positioning portion 31 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0053] In this embodiment, the first positioning portion 12 is a convex column, and the second positioning portion 31 is a concave portion.

[0056] In this embodiment, the housing assembly has a first disassembly state and a second disassembly state, so that the housing assembly is in the first disassembly state by pushing the panel 30 toward the first housing 10 in a preset direction until the first positioning portion 12 and the second positioning portion 31 are limitedly matched and the first clamping portion 11 and the third clamping portion 32 are clamped; when the housing assembly is in the first disassembly state, the fastener 40 is inserted into the first housing 10 and the second housing 20, and the second clamping portion 21 and the fourth clamping portion 33 are clamped, so that the housing assembly is switched from the first disassembly state to the second disassembly state. In this way, the setting of the above-mentioned disassembly state makes the installation and removal of the panel 30 more convenient, and at the same time, the secondary fixation of the fastener 40 further enhances the connection stability between the panel 30 and the first housing 10 and the second housing 20.

The plurality of third reinforcing ribs 212 are arranged at circumferential intervals around the annular structure 211, and each third reinforcing rib 212 is connected to the annular structure 211 and the inner surface of the second shell 20. In this way, the combination of the annular structure 211 and the third reinforcing ribs 212 not only improves the structural strength of the second clamping portion 21, but also can evenly distribute the pressure of the panel 30 on the second shell 20, and maintain the tight connection between the panel 30 and the second shell 20. At the same time, the above arrangement makes the structure of the second clamping portion 21 simpler, easier to process and realize, and reduces the processing cost and difficulty of the second clamping portion 21.
