Description

Technical Field

[0001] This invention relates to the field of industrial touch screen technology, and more particularly to an industrial touch screen that facilitates heat dissipation. Background Technology

[0002] Industrial touchscreens are a type of modern human-computer interaction device widely used in manufacturing, medical, and smart home fields. They accurately detect the position and pressure of a user's finger or stylus by integrating tactile sensors, replacing traditional mechanical buttons. With technological advancements, these devices are no longer limited to visual and auditory feedback but are gradually incorporating tactile feedback functions, using vibration, pulses, or electrostatic forces to simulate real physical touch. This combination not only improves the intuitiveness and efficiency of interaction but also reduces the risk of misoperation, enabling human-computer interaction devices to evolve from one-way command input to a two-way information exchange intelligent interface.

[0003] Industrial touchscreen heat dissipation refers to the process of efficiently dissipating heat from its core heat sources, such as the internal processor, backlight module, and power management system, through methods such as thermal grease, thermal pads, metal heat sinks or vapor chambers, and convection through the casing (natural heat dissipation or active fan cooling), in order to control the temperature of the screen and the entire device.

[0004] Existing industrial touch screens mostly use passive cooling or air cooling for heat dissipation. In the case of air cooling, the airflow usually comes into contact with the fixed internal heat-conducting medium during operation, and the airflow direction is fixed. Therefore, it may result in a narrow heat dissipation coverage area, and local hot spots cannot be effectively eliminated. In addition, the airflow is usually unpurified and can easily contaminate internal components, thereby affecting the long-term stability and heat dissipation performance of the touch screen in harsh industrial environments. Summary of the Invention

[0020] The industrial touch screen disclosed in this invention is mainly used in scenarios where air cooling is used. In such cases, the airflow usually comes into contact with the internal fixed heat-conducting medium and the flow direction is fixed. This may result in a narrow heat dissipation coverage area, inability to effectively eliminate local hot spots, and easy contamination of internal components, affecting the long-term stability and heat dissipation performance of the touch screen.

[0023] Reference Figure 2 and Figures 4-7 In a preferred embodiment, the in-screen heat dissipation unit 8 further includes: A fixing ring frame 805 is set on the back cover 5 of the screen. A heat dissipation fan 801 is set inside the fixing ring frame 805. The outer wall of the heat conduction plate 9 is in contact with the inner wall of the fixing ring frame 805. Multiple airflow pipes 807 are provided on a fixed ring frame 805. Multiple airflow ducts 802 are respectively provided on the output ends of the multiple airflow pipes 807. Multiple airflow holes 806 are provided on the multiple airflow ducts 802. The outer walls of the multiple airflow ducts 802 are in contact with the inner walls of the multiple guide holes 13. Multiple mounting brackets 15 are mounted on the back cover 5 of the screen, and multiple airflow ducts 802 are respectively mounted on the multiple mounting brackets 15.

[0024] In this invention, the in-screen heat dissipation unit 8 further includes: Multiple passive toothed rings 812 are respectively installed on multiple airflow ducts 802; Multiple general-purpose motors 808 are respectively mounted on multiple mounting brackets 15. The output shafts of the multiple general-purpose motors 808 are all connected to toothed gears 811 through couplings. The multiple toothed gears 811 mesh with multiple driven gear rings 812 respectively. Multiple reset torsion springs 813 are respectively disposed on the outside of multiple airflow ducts 802. One end of each reset torsion spring 813 is disposed on the multiple airflow ducts 802, and the other end of each reset torsion spring 813 is disposed on multiple mounting plates 15.

[0025] In this invention, the in-screen heat dissipation unit 8 further includes: The upper cover frame 804 is set on the fixed ring frame 805. Multiple air inlet pipes 810 are set on the upper cover frame 804. Two air inlet chambers 803 are respectively set on the multiple air inlet pipes 810. Both air inlet chambers 803 are set on the screen back cover 5. Two filter plate holders 809 are respectively installed on two air intake chambers 803, and each filter plate holder 809 has two insertion ports 16.

[0026] In this invention, the in-screen heat dissipation unit 8 further includes: Two dust filter inserts 814 are respectively disposed inside two of the inserts 16, and each of the two dust filter inserts 814 is provided with a horizontal plate frame 17. Two tie rods 18 are respectively installed on two horizontal plate frames 17; Two snap-fit ​​connectors 815 are respectively installed on two horizontal frame 17.

[0027] In this invention, the in-screen heat dissipation unit 8 further includes: Multiple snap-fit ​​holes 816 are respectively opened on two filter plate holders 809; Multiple telescopic spring rods 817 are respectively installed on two filter plate frames 809, and the multiple telescopic spring rods 817 are respectively located inside two air intake chambers 803; Multiple sealing plates 818 are respectively set on one end of multiple telescopic spring rods 817, and one outer wall of each sealing plate 818 contacts the outer wall of two filter plate frames 809.

[0028] Specifically, during heat dissipation operation, the cooling fan 801 operates. As the cooling fan 801 operates, the interior of the upper cover frame 804 is under negative pressure, further creating a negative pressure state inside the air inlet pipe 810 and the air inlet chamber 803. This allows external airflow to be drawn into the air inlet chamber 803 through the dust filter insert 814. At this time, the device can purify the external airflow through the dust filter insert 814. Then, the cooling fan 801 delivers the clean airflow to the airflow pipe 807 (during this process, the airflow can contact the heat-conducting plate 9 to dissipate heat, and the airflow will also be cooled after entering the relatively narrow airflow pipe 807). The clean airflow is then further transported... The air is delivered into the airflow duct 802 so that the airflow duct 802 discharges the airflow through the airflow hole 806, thereby directly dissipating heat from the internal heat-conducting medium and components. At this time, the general-purpose motor 808 is running, which drives the toothed gear 811 to rotate. In turn, the toothed gear 811 drives the passive gear ring 812 and the airflow duct 802 to rotate. After the toothed gear 811 rotates to a certain angle, it will briefly separate from the passive gear ring 812. At this time, the reset torsion spring 813 can drive the airflow duct 802 to reset, thereby causing the airflow duct 802 to swing back and forth to increase the heat dissipation coverage area until heat dissipation is completed. When the dust filter insert 814 needs to be replaced, another dust filter insert 814 can be directly inserted into another socket 16. At this time, as the dust filter insert 814 is inserted, it will push the sealing plate 818 and cause the telescopic spring rod 817 to stretch, so as to open the socket 16 to allow airflow to enter. Then, the locking member 815 can be pulled out of the locking hole 816 by the setting of the pull rod 18 and the horizontal plate frame 17, so that the dust filter insert 814 to be replaced can be unplugged and fixed to the filter plate frame 809, thereby completing the disassembly. At the same time, after disassembly, the side socket 16 can be automatically sealed by the telescopic spring rod 817 and the sealing plate 818, completing the replacement. In specific application scenarios, the in-screen heat dissipation unit 8 is suitable for the heat dissipation of industrial touch screens. The in-screen heat dissipation unit 8 uses the dust filter insert 814 to efficiently filter and purify the external airflow, and introduces clean air directly into the housing to directly contact the surface of the heat-generating device for heat exchange. This improves the efficiency of convective heat dissipation and avoids the deposition of dust and oil on the surface of circuit boards and components in industrial environments. It eliminates the risk of short circuits or insulation degradation caused by contaminants and ensures the long-term reliable operation of the touch screen in harsh environments. At the same time, the device is driven by the cooperation of the toothed gear 811 and the reset torsion spring 813, which enables the airflow duct 802 to continuously reciprocate during the heat dissipation process. This allows the high-speed airflow to cover multiple heat-conducting media and device areas in a dynamic sweeping manner, improving the coverage of the airflow duct and avoiding the problems of narrow airflow coverage and local hot spots. This further improves the heat dissipation effect of the device. It should be noted that after the clean airflow is delivered to the airflow pipe 807 by the cooling fan 801, it enters the airflow pipe 802 with a smaller cross section. At this time, the airflow velocity can be increased in the contraction channel and the temperature can be reduced, so that the high-speed low-temperature airflow can be sprayed to the target heat-generating area through the airflow hole 806, which significantly enhances the local convective heat transfer coefficient and further improves the heat dissipation efficiency. The two dust filter inserts 814 are arranged with side-by-side insertion ports 16. When a single filter needs to be replaced, the new filter can be directly inserted into the other unused insertion port 16 to automatically push open the sealing plate 818 and connect the air passage. Then the old filter can be pulled out, and the insertion port 16 is automatically sealed by the sealing plate 818 driven by the telescopic spring rod 817. This process can be completed while the cooling fan 801 is running continuously, which improves the convenience of maintenance and the continuous operation effect of the equipment.

[0029] Reference Figure 2 , Figure 3 and Figures 8-10 In a preferred embodiment, the screen removal module 7 further includes: Mounting sleeve 701 is disposed inside mounting slot 10, and retraction spring rod 702 is disposed inside mounting sleeve 701; Mounting member 706 is mounted on mounting frame 701, and mounting member 706 is provided with pull ring rod 705.

[0030] In this invention, the screen removal and installation module 7 further includes: The inner frame 707 is mounted on the mounting rod 706 and is located inside the mounting sleeve 701. Two shaft rods 708 are mounted on the inner frame 707, and two mounting plates 704 are respectively mounted on the two shaft rods 708. Multiple limit stops 709 are provided on the inner frame 707; Two torsion springs 710 are respectively disposed on the outside of the two shaft members 708. One end of each torsion spring 710 is disposed on the two mounting plates 704, and the other end of each torsion spring 710 is disposed on the inner frame 707.

[0031] In this invention, the screen removal and installation module 7 further includes: A connecting bracket 703 is provided on the inner frame 707 and is located between two mounting plates 704. One end of the retraction spring rod 702 is provided on the connecting bracket 703. The positioning ring 712 is located inside the mounting sleeve 701; The positioning plate 711 is mounted on the mounting plate and is located below the positioning ring 712.

[0032] Specifically, during maintenance and disassembly, the mounting rod 706 is raised by pulling the ring rod 705 until the locking plate 711 moves above the locking ring 712. At this time, rotating the mounting rod 706 will lock the locking ring 712 into position with the locking plate 711. Simultaneously, the retraction spring rod 702 is stretched, and the mounting plate 704, along with the inner frame 707 and the mounting rod 706, contacts the housing of the mounting sleeve 701 and retracts into it. At this time, the screen back cover 5 can be directly disassembled for maintenance and other operations. During installation, the mounting rod 706 is rotated in the opposite direction to release the locking ring 712 from locking the locking plate 711. At this time, the retraction spring rod 702 will drive the connecting bracket 703, inner frame 707 and other structures to reset. Simultaneously, as the inner frame 707 descends, the mounting plate 704 can be reset and unfolded under the action of the torsion spring 710 to lock the screen back cover 5 after unfolding, thus quickly completing the installation. In specific application scenarios, the rear screen disassembly and assembly module 7 is suitable for the maintenance and disassembly / assembly of industrial touch screens. Specifically, the rear screen disassembly and assembly module 7 uses the pull ring rod 705 to pull the mounting rod 706, and with the rotation and locking mechanism of the locking ring 712 and the locking plate 711, the device can quickly disassemble and install the rear screen cover 5 without the need for external tools. This greatly simplifies the maintenance, replacement, and repair process of the internal heat dissipation components and circuit devices of the industrial touch screen, effectively shortening equipment downtime. At the same time, with the pre-tightening force of the retraction spring rod 702, during installation, simply rotate the mounting rod 706 in the opposite direction to release the locking position. The retraction spring rod 702 will automatically drive the inner frame 707 and the mounting plate 704 to reset. Simultaneously, the torsion spring 710 drives the mounting plate 704 to automatically unfold and lock the rear screen cover 5, realizing a self-locking function. This avoids the risk of loosening due to vibration in traditional screw connections and ensures the long-term stability of the equipment in industrial vibration environments.

[0033] Working principle: During maintenance and disassembly, the mounting rod 706 is pulled up by the pull ring rod 705 until the locking plate 711 moves above the locking ring 712. At this time, the mounting rod 706 is rotated so that the locking ring 712 locks into the locking plate 711. At the same time, the retraction spring rod 702 is stretched, and the mounting plate 704 contacts the housing of the mounting sleeve frame 701 as the inner frame 707 and the mounting rod 706 rise, thus retracting into its interior. At this time, the screen back cover 5 can be directly disassembled for maintenance and other operations. During installation, the mounting rod 706 is rotated in the opposite direction so that the locking ring 712 releases its locking position on the locking plate 711. At this time, the retraction spring rod 702 can drive the connecting bracket 703, inner frame 707 and other structures to reset. At the same time, as the inner frame 707 descends, the mounting plate 704 can be reset and unfolded under the action of the torsion spring 710 so as to lock the screen back cover 5 after unfolding, thus quickly completing the installation. During heat dissipation operation, the cooling fan 801 operates. As the cooling fan 801 operates, the interior of the upper cover frame 804 is under negative pressure, further creating a negative pressure environment inside the air inlet pipe 810 and the air inlet chamber 803. This allows external airflow to be drawn into the air inlet chamber 803 through the dust filter insert 814. At this point, the device can purify the external airflow through the dust filter insert 814. Afterwards, the cooling fan 801 delivers the clean airflow to the airflow pipe 807, and further to the airflow duct 802, so that the airflow duct 802 directs the airflow from... Airflow through vent 806 is discharged, thereby directly dissipating heat from the internal heat-conducting medium and components. At this time, the general-purpose motor 808 is running, which drives the toothed gear 811 to rotate. This causes the toothed gear 811 to drive the passive gear ring 812 and the airflow duct 802 to rotate. After the toothed gear 811 rotates to a certain angle, it will briefly separate from the passive gear ring 812. At this time, the reset torsion spring 813 can drive the airflow duct 802 to reset, thereby causing the airflow duct 802 to swing back and forth to increase the heat dissipation coverage area until heat dissipation is completed. When the dust filter insert 814 needs to be replaced, another dust filter insert 814 can be directly inserted into another socket 16. At this time, as the dust filter insert 814 is inserted, it will push the sealing plate 818 and cause the telescopic spring rod 817 to stretch, so as to open the socket 16 to allow airflow to enter. Then, the locking member 815 can be pulled out of the locking hole 816 by the setting of the pull rod 18 and the horizontal plate frame 17, so that the dust filter insert 814 to be replaced can be unplugged and fixed to the filter plate frame 809, thereby completing the disassembly. At the same time, after disassembly, the side socket 16 can be automatically sealed by the telescopic spring rod 817 and the sealing plate 818, completing the replacement.
