Embodiment 1
[0034] An expandable chassis structure, comprising a heat dissipation base 1 and a chassis body 2 installed on the upper part of the heat dissipation base 1, the heat dissipation base 1 is used to evacuate the heat delivered from the heat dissipation base 1 to the external environment, so as to realize the connection between the external environment and the chassis body. 2 The exchange of internal temperature, the interior of the chassis body 2 is used to accommodate and carry working components, the side of the chassis body 2 is reserved with a chassis expansion opening 3, and the bottom of the chassis expansion opening 3 is movably installed with a turning plate 5 through a rotating shaft 4, and through the turning plate The closing of 5 will close the opening 3 of the chassis. Similarly, the opening of the chassis body 2 is realized by opening the flipping plate 5. The flipping plate 5 is movably matched with the opening 3 of the chassis. The inner side of the flipping plate ...
Embodiment 2
[0039] In this embodiment, heat dissipation silica gel is coated between the heat dissipation base 1 and the bottom of the chassis body 2 , and the heat inside the chassis body 2 can be diffused to the heat dissipation base 1 more quickly by coating the heat dissipation silica gel.
Embodiment 3
[0041] In this embodiment, the rotating shaft 4 is inserted with a flipping plate expansion spring. Through the setting of the flipping plate expansion spring, when the reel 8 is unwound, the flipping plate 5 is automatically opened under the action of the external force of the flipping plate expansion spring itself.
