Description

Technical Field

[0001] The present invention relates to the field of touch screens, and in particular to a touch screen assembly and a display device having the same. Background Art

[0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to the pre-programmed program, which can be used to replace the mechanical button panel and create vivid audio and video effects through the liquid crystal display screen. As the latest computer input device, the touch screen is a simple, convenient and natural way of human-computer interaction. It gives multimedia a brand new look and is a very attractive new multimedia interactive device. It is mainly used in public information query, industrial control, military command, electronic games, multimedia teaching, etc. However, the existing touch screen has certain disadvantages when it is used. The chip on the motherboard of the touch screen will generate a lot of heat during use. Therefore, heat dissipation holes are provided on the shell of the touch screen for heat dissipation. During use, dust can easily enter the device shell through the heat dissipation holes. After entering the device shell, dust can easily adhere to the motherboard. Because the dust contains moisture, the electronic components will become damp or even corroded. Dust adsorbed on the surface of the circuit board will reduce the insulation resistance between adjacent printed lines, affecting the normal operation of the circuit. In severe cases, it will cause short circuit failure and burn the motherboard. Summary of the invention

[0003] The main purpose of the present invention is to provide a touch screen assembly and a display device having the same, which can effectively solve the problems mentioned in the background technology.

[0030] Embodiment 2

[0031] In order to improve the heat dissipation effect, the heat conduction mechanism 9 includes a heat conduction plate 901, a heat conduction column 902, a connecting bolt 903, a first clamping plate 904, a connecting screw hole 905, a second clamping plate 906 and a spring 907. The first clamping plate 904 is arranged on the upper surface of the heat dissipation pipe 601, and the second clamping plate 906 is arranged on the lower surface of the heat dissipation pipe 601. The first clamping plate 904 and the second clamping plate 906 are provided with connecting screw holes 905 at the four corners. Bolt 903, a heat-conducting column 902 is fixedly installed on the upper surface of the first clamping plate 904, a heat-conducting plate 901 is fixedly installed on the top of the heat-conducting column 902, a spring 907 is fixedly installed on the bottom plate of the second clamping plate 906, and the connecting bolt 903 is connected to the first clamping plate 904 and the second clamping plate 906 through the connecting screw hole 905. The first clamping plate 904 and the second clamping plate 906 are fixed to the heat dissipation pipe 601 through the connecting bolt 903. Because the end of the air intake pipe 706 is fixed A one-way air intake valve 707 is fixedly installed, and the heat dissipation pipeline 601 is connected to the air supply cylinder 703 through the air supply port 704. The one-way air outlet valve 705 only allows the gas in the air supply cylinder 703 to be discharged, and the one-way air intake valve 707 only allows the external gas to enter the air supply cylinder 703. Therefore, during the reciprocating motion of the piston 702, the external cold air will flow rapidly in the heat dissipation pipeline 601. When the cold air flows rapidly in the heat dissipation pipeline 601, one end of the heat-conducting column 902 can be connected to the heat dissipation pipeline 601.
