Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, specifically a resistive touch screen protection device. Background Technology

[0002] A resistive touchscreen is a sensor that converts the physical location (X, Y) of a touch point within a rectangular area into voltages representing the X and Y coordinates. Many LCD modules use resistive touchscreens, which can generate screen bias voltages using four, five, seven, or eight lines, while simultaneously reading back the voltage at the touch point.

[0003] Existing resistive touch displays typically employ a frame-type protective casing, using stepped grooves to accommodate screen installation. The back panel and protective casing together protect the resistive touchscreen, effectively improving production efficiency and reducing the risk of installation damage. However, existing resistive touch displays lack adequate protection and proper heat dissipation. In dusty or high-temperature environments, they are highly susceptible to short circuits due to dust accumulation and poor heat dissipation, leading to malfunctions that severely impact equipment stability and lifespan. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a protective device for resistive touchscreens. Through the cooperation of springs and heat dissipation components, it solves the problem that existing resistive touchscreens lack heat dissipation structures and are prone to malfunctions due to dust accumulation, short circuits, and poor heat dissipation in dusty or high-temperature environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A resistive touchscreen protection device includes a protective housing with an embedded groove inside; a resistive touchscreen installed in the embedded groove, with a display screen attached to the touchscreen; a threaded hole on the protective housing; a through hole corresponding to the threaded hole on the display screen; a bolt installed in the through hole; the bolt being threadedly connected to the threaded hole to fix the display screen inside the protective housing, preventing loosening between the display screen and the protective housing; and heat dissipation components installed on both sides of the protective housing to dissipate heat in a timely manner and prevent components from aging due to high temperature.

[0007] Preferably, the heat dissipation component includes a dustproof mesh, and heat dissipation holes are provided on both sides of the protective shell, with the dustproof mesh fixed inside the heat dissipation holes.

[0008] Preferably, a buffer pad is installed in the embedded groove. The buffer pad is made of EVA material, which helps to absorb external impact and protect the resistive touch screen and display screen from collision damage.

[0009] Preferably, a spring is fixed to the protective shell, and a back panel is fixed to the other end of the spring, which facilitates flexible adjustment of the back panel position and makes it easy to adapt to the installation and disassembly of internal components of different sizes.

[0010] Preferably, a positioning groove is provided on the back panel, and an electromagnetic shielding plate is installed in the positioning groove, which is conducive to the precise fixing of the electromagnetic shielding plate and facilitates the formation of a complete electromagnetic shielding space.

[0011] Preferably, the protective shell has a light-transmitting cavity on the front, and an indicator light is fixed inside the light-transmitting cavity. The indicator light is wirelessly connected to the display screen via Bluetooth, which is conducive to intuitively displaying the device status and making it easy for users to quickly understand the device's operating status.

[0012] Preferably, a sealing strip is installed at the joint between the protective shell and the back panel. The sealing strip is arranged along the contact edge of the two, which helps to prevent dust and moisture from entering and improves the sealing performance of the protective device.

[0013] Preferably, the outer surface of the protective shell is provided with anti-slip texture, and the protective shell is made of high-strength aluminum alloy material, which helps to enhance handheld stability and facilitate the operation of the equipment.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its designed heat dissipation components, ensures that when the resistive touchscreen and display screen are operating, the heat generated causes the temperature inside the protective casing to rise. This heat is then dissipated through convection current created by the heat dissipation holes and dust filter, allowing the heat to escape from the protective casing. Unlike traditional protective devices, this design ensures that heat is dissipated promptly during prolonged operation, whether under continuous high load or in high-temperature environments, effectively protecting internal components and significantly improving the heat dissipation performance of the protective device.

[0016] 2. This utility model utilizes a designed EVA buffer pad. When the resistive touchscreen is installed, it is embedded in the groove of the protective shell, allowing the resistive touchscreen and display screen to be supported by the EVA buffer pad. This disperses the pressure on the contact surface, unlike traditional direct contact installation. It ensures that during daily use, whether it is slightly squeezed or subjected to small external forces, the resistive touchscreen and display screen can be effectively protected, truly reducing the risk of physical damage and greatly improving the protection effect of the equipment.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Example:

[0027] Please see Figure 1 - Figure 6 A resistive touchscreen protection device includes a protective housing 1 with an embedded groove 2 inside; a resistive touchscreen 3 installed in the embedded groove 2, a display screen 4 attached to the resistive touchscreen 3, a threaded hole 5 on the protective housing 1, a through hole 6 corresponding to the threaded hole 5 on the display screen 4, a bolt 7 installed in the through hole 6, the bolt 7 being threadedly connected to the threaded hole 5, thereby fixing the display screen 4 inside the protective housing 1 to prevent loosening between the display screen 4 and the protective housing 1; and heat dissipation components 8 installed on both sides of the protective housing 1, which dissipate heat in time to prevent components from aging due to high temperature.

[0028] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5Through the designed heat dissipation component 8, when the resistive touch screen 3 and display screen 4 are working, the heat generated causes the temperature inside the protective housing 1 to rise. This causes air to convect through the heat dissipation holes 10 and the dust filter 9, thereby expelling the heat from the protective housing 1. Unlike traditional protective devices, this ensures that heat can be dissipated in a timely manner during long-term operation, whether under continuous high load or in a high-temperature environment, truly achieving effective heat dissipation protection for internal components and greatly improving the heat dissipation effect of the protective device.

[0030] Among them, the heat dissipation component 8 includes a dustproof mesh 9, and the protective shell 1 has heat dissipation holes 10 on both sides, with the dustproof mesh 9 fixed inside the heat dissipation holes 10;

[0031] In addition, a buffer pad 11 is installed in the embedded groove 2. The buffer pad 11 is made of EVA material, which is conducive to absorbing external impact and protecting the resistive touch screen 3 and the display screen 4 from collision damage.

[0032] Meanwhile, a spring 12 is fixed on the protective shell 1, and a back plate 13 is fixed to the other end of the spring 12, which facilitates flexible adjustment of the position of the back plate 13 and makes it easy to adapt to the installation and disassembly of internal components of different sizes.

[0033] In this technical solution, such as Figure 1 - Figure 6 As shown, a positioning groove 14 is provided on the back panel 13, and an electromagnetic shielding plate 15 is installed in the positioning groove 14, which is conducive to the precise fixation of the electromagnetic shielding plate 15 and the formation of a complete electromagnetic shielding space; a light-transmitting cavity 16 is provided on the front of the protective shell 1, and an indicator light 17 is fixed in the light-transmitting cavity 16. The indicator light 17 is wirelessly connected to the display screen 4 via Bluetooth, which is conducive to intuitively displaying the device status and making it easy for users to quickly understand the device's operating status.

[0034] Among them, a sealing strip 18 is installed at the joint between the protective shell 1 and the back panel 13. The sealing strip 18 is arranged along the contact edge of the two, which helps to block dust and moisture from entering and improves the sealing performance of the protective device.

[0035] In addition, the outer surface of the protective shell 1 is provided with anti-slip texture 19. The protective shell 1 is made of high-strength aluminum alloy, which helps to enhance hand stability and facilitate the operation of the equipment.

[0036] The working principle of heat dissipation component 8 is explained below:

[0037] First, the resistive touch screen 3 with the display screen 4 attached is securely installed in the embedded groove 2 of the protective housing 1 by the threaded connection of the bolt 7 and the threaded hole 5, providing a stable foundation for the core operating components of the entire device.

[0038] Secondly, the heat dissipation components 8 on both sides play a role, and the heat dissipation holes 10 and the dustproof mesh 9 work together to ensure air circulation while preventing dust from entering, and to dissipate the heat generated by the resistive touch screen 3 and the display screen 4 in a timely manner, so as to avoid the components aging due to high temperature.

[0039] Then, when the device is subjected to external impact or vibration, the EVA material buffer pad 11 embedded in the groove 2 absorbs the impact force and protects the internal components. At the same time, the back plate 13 connected by the spring 12 can be flexibly adjusted to adapt to the installation of components of different sizes. The electromagnetic shielding plate 15 in the positioning groove 14 of the back plate 13 resists external electromagnetic interference and ensures stable operation of the equipment. The sealing strip 18 at the joint between the protective shell 1 and the back plate 13 prevents dust and moisture from entering.

[0040] Finally, the indicator light 17 inside the light-transmitting cavity 16 on the front of the protective shell 1 is wirelessly connected to the display screen 4 via Bluetooth to provide real-time feedback on the device's operating status. The anti-slip texture 19 on the outer surface of the protective shell 1, combined with the high-strength aluminum alloy material, facilitates stable hand operation for the user. It should be noted that the resistive touch screen 3, the display screen 4, the electromagnetic shielding plate 15, and the indicator light 17 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed. Therefore, they will not be repeated in the manual.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principle, the implementation of the present invention may have any variations or modifications.
