Detailed Description of the Preferred Embodiments

[0023] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0024] Such as Figures 1-5As shown in the figure, a helmet with a refrigeration and cooling mechanism includes a helmet body 1. A protective cover 2 is provided on the outer wall of the helmet body 1. A refrigeration and cooling device 3 is provided on the top of the helmet body 1. The refrigeration and cooling device 3 includes a fixed rod 31. The bottom of the fixed rod 31 is fixedly connected to the top of the helmet body 1. The top of the fixed rod 31 is fixedly connected to a motor 32. The output shaft of the motor 32 is fixedly connected to a rotating shaft 33. An L-shaped rod 34 is fixedly connected to the circumferential surface of the rotating shaft 33. The bottom of the L-shaped rod 34 is fixedly connected to an L-shaped fixing plate 35. A contact block 36 is fixedly connected to the lower part of the inner wall of the L-shaped fixing plate 35. A connecting arc rod 37 is slidably connected to the top of the helmet body 1. One end of the connecting arc rod 37 is fixedly connected to an arc block 38. A plurality of heat dissipation fins 39 are fixedly connected to the outer wall of the connecting arc rod 37. A fixing block 310 is fixedly connected to the outer wall of the helmet body 1. A first spring 311 is arranged between the connecting arc rod 37 and the fixing block 310;

[0025] A plurality of heat dissipation fins 39 are in contact with the helmet body 1, and there is a gap between the connecting arc rod 37 and the L-shaped fixing plate 35;

[0026] The arc block 38 is located on the displacement track of the contact block 36, and the arc block 38 is in contact with the helmet body 1;

[0027] According to the above structure, when the weather is hot, the heat dissipation fins 39 will conduct the heat of the helmet out, making the helmet feel cooler on the head. Start the motor 32, and the output shaft of the motor 32 will make the rotating shaft 33 rotate. The rotation of the rotating shaft 33 will drive the L-shaped rod 34 to rotate. The rotation of the L-shaped rod 34 will drive the L-shaped fixing plate 35 to rotate. The rotation of the L-shaped fixing plate 35 will drive the contact block 36 to rotate. The rotation of the contact block 36 will contact the arc block 38, so that the arc block 38 will squeeze the first spring 311 through the connecting arc rod 37. When the rotation of the contact block 36 does not contact the arc block 38, the first spring 311 will drive the connecting arc rod 37 to rebound through its own elastic force. So reciprocating, the connecting arc rod 37 realizes reciprocating motion. The reciprocating motion of the connecting arc rod 37 will drive the heat dissipation fins 39 to perform reciprocating motion, thereby enhancing the heat dissipation effect of the heat dissipation fins 39.

[0028] As Figures 1-5 shown, an air flow guiding device 4 is provided on the top of the inner wall of the L-shaped fixing plate 35. The air flow guiding device 4 includes a long block 41. The top of the long block 41 is fixedly connected to the top of the inner wall of the L-shaped fixing plate 35. A limiting block 42 is fixedly connected to the side of the long block 41. An arc plate 43 is slidably connected to the side of the long block 41. A second spring 44 is arranged between the arc plate 43 and the limiting block 42;

[0029] The arc plate 43 is in contact with the connecting arc rod 37 and the heat dissipation fins 39;

[0030] The arc plate 43 is located below the limiting block 42, and there is a gap between the arc plate 43 and the limiting block 42;

[0031] According to the above structure, the rotation of the L-shaped fixing plate 35 will drive the long block 41 to rotate, the rotation of the long block 41 will drive the arc plate 43 to rotate, and the rotation of the arc plate 43 will make the air flow velocity around the heat dissipation fin 39 faster, thereby improving the heat conduction efficiency of the heat dissipation fin 39.
