Preferably, the center of the circular arc groove 121 is located on the axis of the hinged end of the plate body 21, because the plate body 21 performs the turning motion with the hinged end of the plate body 21 as the center.

In order to ensure that a movable sealing structure is formed between the plate body 21 and the shell 11, on the basis of ensuring that the plate body 21 can be freely opened and closed, external impurities are effectively prevented from entering the shell 11, two side surfaces of the growth plate body 21 are respectively and tightly abutted against the inner side surfaces of the two side plates 12, and the end side surface of the non-hinged end of the plate body 21 and the abutting surface of the opening 16 are both outward inclined surfaces.

The working principle is as follows:

when the rear selector is not in operation, the plate body 21 is tightly embedded in the opening 16 of the shell 11, so as to achieve the purposes of sealing and protecting. At this time, the second beam 25 is positioned at the inner end of the sliding groove 151 of the projection 15.

When the rear selector works to cause the temperature in the shell 11 to rise sharply, the motor 5 is started to drive the moving gear 4 to rotate and drive the spur rack 3 to move towards the outer end of the rack groove 18, so that the second beam 25 is pulled to move towards the outer end of the sliding groove 151; because the first beam 23, the net plate 24 and the second beam 25 are fixedly connected with each other, when the second beam 25 moves towards the outer end of the chute 151, the net plate 24 is pried to rotate around the rotating shaft of the first beam 23, so that the original inclined lodging shape is changed into the upright shape, one end of the plate body 21 is supported, and the opening 16 is exposed, so that heat can be discharged; at the same time, the fan 6 is activated to generate a convective circulation of air for heat dissipation.

In the process, because the two sides of the plate body 21 and the inner side surface of the side plate 12 are tightly abutted, and meanwhile, heat is discharged through the screen plate 24, the shell 11 and the plate body 21 still have a good protection effect, and dust or other particles in the external environment are prevented from entering the shell 11 to lose components.

Compared with the traditional heat dissipation mode, the heat dissipation device does not increase too many heat dissipation components with larger volume, but expands the range of heat discharge as much as possible on the basis of keeping effective protection of the components, thereby effectively improving the heat dissipation efficiency and the heat dissipation effect.
