It can be understood that there is a preset distance between the heat dissipation element 300 and the side wall of the cavity 101, so that when the heat dissipation element 300 is working, the heat dissipation element 300 is cooled, and the components in the heat dissipation element 300 are isolated from the bottom shell 100, reducing the impact of static electricity on the components. In some embodiments, the heat dissipation element 300 includes a controller mainboard, a control circuit board, etc.

[0027] Optionally, the heat dissipation element 300 is welded to the side wall of the cavity 101 in the bottom shell 100, so that there is a preset distance between the heat dissipation element 300 and the inner side of the cavity 101; or, a clamping portion is provided on the side of the heat dissipation element 300 facing the bottom shell 100, and the number of the clamping portions can be set to be multiple. By providing a clamping groove that is clamped with the clamping portion on the side wall of the bottom shell 100, during installation, the clamping portion is clamped with the clamping groove, so that the heat dissipation element 300 and the bottom shell 100 are relatively fixed, so that there is a preset distance between the heat dissipation element 300 and the inner side of the bottom shell 100.

[0028] In the above embodiment, the host assembled by the bottom shell 100 and the cover plate 400 has a simple structure, and there is a preset distance between the heat dissipation element 300 and the inner side of the cavity 101, so that when the heat dissipation element 300 is working, the heat dissipation element 300 is cooled, and the components in the heat dissipation element 300 are isolated from the bottom shell 100, reducing the impact of static electricity on the components. In this way, the probability of insufficient heat dissipation performance due to the high integration of existing home hosts is effectively reduced, and the service life of the host is extended.

[0029] In one embodiment, the whole-house smart hub home host also includes: a plurality of motherboard fixing columns 200, wherein the plurality of motherboard fixing columns 200 are arranged in the cavity 101, the first end of the motherboard fixing column 200 is connected to the side wall of the cavity 101, and the second end of the motherboard fixing column 200 is connected to the side of the heat dissipation component 300 close to the bottom shell 100.

[0030] In this embodiment, there are four mainboard fixing columns 200, and the four mainboard fixing columns 200 are respectively installed vertically at the four corners of the cavity 101. Specifically, the number of mainboard fixing columns 200 is mainly to achieve stability between the heat dissipation element 300 and the bottom shell 100, so that the heat dissipation element 300 can be more stably arranged in the bottom shell 100. The first end of the mainboard fixing column 200 is connected to the side wall of the cavity 101, and the heat dissipation element 300 is connected to one end (i.e., the second end) of the mainboard fixing column 200 away from the bottom shell 100 to fix the four corners of the heat dissipation element 300. The heat dissipation element 300 can be fixed to the mainboard fixing column 200 by screwing, clamping, welding, etc. Optionally, the heat dissipation element 300 is welded to the end of the mainboard fixing column 200 away from the bottom shell 100, so that there is a preset distance between the heat dissipation element 300 and the inner side of the bottom shell 100; or, a clamping portion is provided on the side of the heat dissipation element 300 facing the bottom shell 100, and the number of the clamping portions can be set to multiple. By providing a clamping groove that is clamped with the clamping portion at the end of the mainboard fixing column 200 away from the bottom shell 100, during installation, the clamping portion is clamped with the clamping groove, so that the heat dissipation element 300 and the mainboard fixing column 200 are relatively fixed, so that there is a preset distance between the heat dissipation element 300 and the inner side of the cavity 101.

[0031] In one embodiment, the whole-house smart hub home host also includes: a cover fixing column 600, one end of the cover fixing column 600 is connected to the end of the mainboard fixing column 200 away from the bottom shell 100, the mainboard fixing column 200 includes an abutment portion 201 and a step portion 202, the abutment portion 201 is connected to the cover fixing column 600 at one end away from the bottom shell 100, and the side of the heat dissipation component 300 close to the bottom shell 100 abuts against the step portion 202.

[0032] In this embodiment, the cover plate fixing column 600 is vertically arranged at one end of the mainboard fixing column 200 away from the bottom shell 100, and one end of the cover plate fixing column 600 is connected to one end of the mainboard fixing column 200 away from the bottom shell 100. Figure 4 As shown, specifically, the mainboard fixing column 200 includes an abutting portion 201 and a step portion 202.

[0033] In one embodiment, one end of the mainboard fixing column 200 away from the bottom case 100 is made of elastic material.

[0034] In this embodiment, by setting the end of the motherboard fixing column 200 away from the bottom case 100 to be an elastic material, such as a rubber material, the rubber material is soft, elastic, and has good insulation properties, so as to block the hard contact between the motherboard fixing column 200 and the heat dissipation element 300, effectively prevent shock, and also insulate the heat dissipation element 300 from the bottom case 100, prevent grounding, short circuit, and protect data security. In some embodiments, optionally, a gasket can also be set between the motherboard fixing column 200 and the heat dissipation element 300, which is also effective in preventing shock and insulating the heat dissipation element 300 from the bottom case 100.

Due to the material of the cover plate 400 and the bottom shell 100, the heat generated by the heat dissipation element 300 can be conducted to the outside of the home host, and the heat generated by the heat dissipation element 300 can be dissipated, thereby reducing the probability of the home host malfunctioning due to excessive heat accumulation or internal overheating of the host. In addition, due to the oxidation property of aluminum alloy, the surface color of the bottom shell 100 and the cover plate 400 is oxidized, so that the bottom shell 100 and the cover plate 400 have a strong metallic texture, bright color, and are more beautiful.
