[0002] The display touch device motherboard is mainly composed of key components such as processor, memory, storage, touch IC, etc. Among them, the processor is responsible for processing various data and instructions, while memory and storage are used to store data and programs. The touch IC is an important chip on the motherboard, responsible for receiving and processing signals from the touch screen, and then transmitting these signals to the processor, thereby achieving precise control of the screen.

[0003] During motherboard installation, a snap-on installation method is commonly used to improve efficiency. However, while this method increases installation speed, it often struggles to balance optimization of spatial layout and heat dissipation structure, thus affecting heat dissipation efficiency. During normal operation, the motherboard releases a large amount of heat. If this heat cannot be dissipated in a timely manner, the motherboard will remain in a high-temperature state for a long time, which may eventually damage electronic components.

[0024] It should be noted that: the touch screen motherboard 31 is clamped in the placement slot and fixed by moving the screw block 41 and other mechanisms. At this time, the touch screen motherboard 31 is in a suspended state, and with the cooperation of the fixing plate 5, the heat dissipation mechanism is placed in a position close to the touch screen motherboard 31. This installation method can improve the installation speed while also taking into account the optimization of the space layout and the heat dissipation structure.

[0025] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 The power mechanism includes a bidirectional threaded rod 4, the right inner wall of the protective shell 2 is rotatably connected to the bidirectional threaded rod 4, the outer side of the bidirectional threaded rod 4 is connected to a movable threaded block 41 through a thread, and a connecting column 42 is fixedly installed on the top of the movable threaded block 41. The top of the connecting column 42 is fixedly installed to the bottom of the fixed plate 5, and a rotating disc is fixedly installed in the middle position of the bidirectional threaded rod 4. An arc hole is opened at the bottom of the protective shell 2, and the outer side of the rotating disc extends out of the bottom of the protective shell 2 through the arc hole.

[0026] It should be noted that the internal structure of the power mechanism drives the clamping notches 51 on both sides to move to clamp and fix the touch motherboard 31 , and drives the heat dissipation mechanism to move to a position close to the touch motherboard 31 .

[0027] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The protective shell 2 is provided with a ventilation hole group on all sides, and the horizontal height of the touch mainboard 31 is located in the middle position of the ventilation hole group.

[0028] It should be noted that the cooperation between the plurality of ventilation hole groups and the heat dissipation mechanism can accelerate the circulation of air at the top and bottom of the touch control mainboard 31 .

[0029] In the embodiments of the present invention, please refer to Figure 3 The left side of the cube air vent 52 is designed with rounded corners, and the left side of the fixing plate 5 is also designed with rounded corners.

[0030] It should be noted that the air intake range of the square air vent 52 is expanded to facilitate the clamping of the touch panel 31 in the clamping notch 51 .

[0031] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 There are two groups of heat dissipation mechanisms, which are symmetrically arranged on the left side of the fixed plate 5.

[0032] It should be noted that the two sets of heat dissipation mechanisms operate synchronously to dissipate heat from the top and bottom of the touch control mainboard 31 at the same time.

[0033] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 The bottom of the movable threaded block 41 slides and fits with the bottom inner wall of the protective shell 2 .

[0034] It should be noted that the movable threaded block 41 is restricted so that the movable threaded block 41 is driven to move when the bidirectional threaded rod 4 rotates.

[0035] The working principle of the display touch device motherboard provided by the present invention is as follows: the touch motherboard 31 is placed on the top of the positioning plate 3, so that the touch motherboard 31 is stuck in the placement slot, so that the touch motherboard 31 is in a suspended state, and the rotating disk is driven by hand to rotate, and the rotating disk drives the two-way threaded rod 4 to rotate. The rotation of the two-way threaded rod 4 drives the moving thread block 41 to move to the middle position of the two-way threaded rod 4 under the restriction of the bottom of the protective shell 2, and the moving thread block 41 drives the fixing plate 5 to move to the middle position of the two-way threaded rod 4 through the connecting column 42, and the fixing plate 5 drives the clamping notch 51 and the heat dissipation mechanism to move to the middle position of the two-way threaded rod 4. Similarly, the working principle of the other clamping notch 51 and the remaining heat dissipation mechanisms is the same as above. The clamping notches 51 at both ends move synchronously to the middle position of the two-way threaded rod 4 to clamp and fix the left and right ends of the touch motherboard 31, and at the same time fix The fixed plate 5 drives the heat dissipation mechanism to move to a position close to the touch motherboard 31, and fixes the protective shell 2 to the bottom of the display screen 1 with screws. When the touch motherboard 31 generates a lot of heat during operation, since the touch motherboard 31 is in a suspended state, the top and bottom of the touch motherboard 31 can dissipate the heat. At this time, multiple heat dissipation fan blades 54 rotate, and absorb air and dissipate heat from the top and bottom of the touch motherboard 31 on the left and right sides of the touch motherboard 31, quickly absorbing the heat dissipated from the top and bottom of the touch motherboard 31, thereby accelerating the air flow at the top and bottom of the touch motherboard 31, thereby improving the heat dissipation efficiency of the touch motherboard 31, so that although the touch motherboard 31 will release a lot of heat during normal operation, this heat can be dissipated quickly and effectively, ensuring that the touch motherboard 31 is maintained within a suitable temperature range, avoiding the problem of damage to electronic components caused by long-term high temperature.
