Description

Technical Field

[0001] The utility model relates to a middle frame structure device for heat dissipation and dust prevention of a color screen wire controller. Background Art

[0002] Today's color screen wired remote controllers are beautiful, elegant, and have large display screens and are user-friendly. However, the power consumption of the color screen wired remote controller itself is much greater than that of traditional wired remote controllers, and the heat generated is also much greater, resulting in a lot of heat generated by the color screen wired remote controller. Excessive heat will easily burn the color screen wired remote controller. In addition, due to the above reasons, the internal temperature of the color screen wired remote controller is too high, and many color screen wired remote controllers cannot directly collect the ambient temperature through themselves. Utility Model Content

[0003] In view of the above problems, the utility model provides a middle frame structure device for heat dissipation and dust prevention of a color screen wired controller, which effectively solves the problems pointed out in the background technology.

[0004] The technical solution adopted by the utility model is:

[0005] A middle frame structure device for heat dissipation and dust prevention of a color screen wire controller comprises a middle frame body, wherein the front side of the middle frame body is a front cavity, and the rear side is a rear cavity, the front cavity and the rear cavity are separated by a partition, and the middle frame body is provided with an air inlet and a temperature detection hole at the bottom of the rear cavity, and exhaust holes are provided on both left and right sides.

[0006] Preferably, the partition is provided with a heat dissipation hole connecting the front cavity and the rear cavity.

[0007] The front cavity is connected to the rear cavity through the heat dissipation holes, so that the heat generated by the LCD screen with the highest heat generation in the front cavity can flow quickly to the rear cavity, ensuring the uniform temperature inside the color screen wired controller.

[0008] Preferably, the middle frame body is provided with a voice hole on the left or right side of the rear cavity.

[0009] The voice hole is used for voice control, which facilitates the transmission of external sound into the color screen wired remote control.

[0010] Preferably, the speech hole and the exhaust hole are the same hole.

[0011] The voice hole shares the exhaust hole on one side, thereby reducing the number of holes on the side of the middle frame and ensuring the strength and aesthetics of the middle frame.

[0012] Preferably, the partition is provided with a heat dissipation transverse groove connecting the front cavity and the rear cavity on the inner side of the air inlet hole.

[0013] Since the front cavity is usually flat, the air inlet cannot be set at the bottom of the front cavity. The utility model connects the bottom of the front cavity and the bottom of the rear cavity through the heat dissipation transverse groove, so that the cold air entering through the air inlet can enter the front cavity and the rear cavity at the same time.

[0014] The utility model sucks in cold air through the air inlet holes at the bottom and discharges hot air through the air outlet holes at the sides, thereby forming a circulating air flow to dissipate heat. At the same time, the air inlet holes and the air outlet holes are respectively arranged at the bottom and the sides, which can prevent external dust from entering the middle frame.

[0015] The utility model is used for detecting the ambient temperature by arranging a temperature detection hole at the bottom. BRIEF DESCRIPTION OF THE DRAWINGS
