[0031] The driving mechanism is installed inside the heat dissipation box 3, and is used for outputting power to the heat dissipation mechanism and the rain protection mechanism. A transmission mechanism is provided between the driving mechanism and the heat dissipation mechanism, and a linkage mechanism is provided between the driving mechanism and the rain protection mechanism. The driving mechanism includes a support plate 9 fixedly connected to the inside of the heat dissipation box 3, and a driving motor 10 is fixedly connected to the support plate 9.

[0032] In this embodiment, the transmission mechanism includes a reducer 11 fixedly connected to the top of the support plate 9, a first output shaft 12 is fixedly connected to one side of the reducer 11, a first pulley 13 is fixedly sleeved on the first output shaft 12, and is fixedly connected to the drive motor 10, a second pulley 14 is fixedly sleeved at the position corresponding to the first pulley 13 on the transmission rod 7, and the second pulley 14 and the first pulley 13 are transmission-connected by the same belt 15.

[0035] Working principle: When in use, on a sunny day, the extended protective plate 20 is stored inside the storage slot, and the positive start of the drive motor 10 drives the first output shaft 12 to rotate, and the rotation of the first output shaft 12 drives the rotation of the first pulley 13, and the rotation of the first pulley 13 drives the second pulley 14 to rotate through the belt 15, and the rotation of the second pulley 14 drives the transmission rod 7 to rotate, and the rotation of the transmission rod 7 drives the rotation of the two first bevel gears 8, and at the same time meshes with the two second bevel gears 6 for transmission, and the rotation of the second bevel gears 6 drives the two connecting rods 4 to rotate, and the rotation of the connecting rod 4 drives the fan blades 5 to rotate synchronously, and the rotation of the fan blades 5 is used to blow air inside the machine body 1 , thereby improving the air flow inside the body 1, and effectively performing rapid heat dissipation and ventilation processing. When the driving motor 10 rotates in the forward direction, the second output shaft 16 is decelerated and rotated through the reducer 11. The rotation of the second output shaft 16 drives the rotation of the fifth bevel gear 17. The rotation of the fifth bevel gear 17 drives the threaded rod 18 to rotate synchronously through the connecting rod 23. The rotation of the threaded rod 18 performs movement and limit processing on the movable plate 19 through the limit spring 27. Since a light rod is provided at one end of the threaded rod 18, and the diameter of the light rod is smaller than the diameter of the threaded hole, therefore, when the movable plate 19 moves to the threaded end of the threaded rod 18, it is moved and limited by the limit spring 27, and is separated from the thread of the threaded rod 18 at the same time;

[0036] When it rains, the driving motor 10 starts in the reverse direction, and at the same time drives the second output shaft 16 to rotate in the reverse direction through the reducer 11, and drives the connecting rod 23 to rotate in the reverse direction. The reverse rotation of the connecting rod 23 drives the threaded rod 18 to rotate in the reverse direction synchronously. At this time, the movable plate 19 is threadedly engaged with the threaded rod 18 through the limit spring 27, thereby driving the extended protection plate 20 to move smoothly along the guide rod 22 through the guide plate 21, and the extended protection plate 20 is extended to increase the rainproof shielding area of ​​the machine body 1, thereby effectively performing rain protection treatment.

[0037] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
