[0031] Display devices are widely used in various scenarios. With the increasing demand for human-computer interaction, touch devices have emerged on the market to provide touch functions, turning non-touch display devices into touch-enabled ones. At the same time, as people pay more attention to eye health, due to the damage to the eyes caused by prolonged use of display devices, there is often a lack of effective measures to protect the eyes after existing non-touch display devices are converted into touch display devices.

[0032] This utility model proposes an assembly with an infrared touch control device and an eye protection panel.

[0033] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the infrared touch device and eye protection panel assembly includes an eye protection panel 100 and an infrared touch device 200. The eye protection panel 100 includes an eye protection panel body 110 and a connecting structure 120 disposed on the eye protection panel body 110. The connecting structure 120 is used for detachable connection with the frame edge 22 of the display area 21 of the computer 20. The infrared touch device 200 includes a mask frame 210 and an infrared touch component disposed inside the mask frame 210. The mask frame 210 is disposed on the side of the eye protection panel 100 away from the display area 21 and is connected to the eye protection panel 100.

[0034] In the technical solution of this utility model, an infrared touch component is provided inside the mask frame 210, and the mask frame 210 is mounted on the eye protection plate 100. The eye protection plate 100 is mounted on a non-touch display device such as a computer 20, thereby connecting the mask frame 210 with the display device. This enables the display device, such as the computer 20, which does not have touch functionality, to have touch functionality, allowing users to directly perform touch operations on the screen with their fingers or styluses, achieving convenient human-computer interaction and improving the interactivity of the device. In addition, the eye protection plate 100 can effectively filter harmful light such as blue light and ultraviolet light emitted from the display area 21, reducing the amount of light emitted. To reduce eye strain and other symptoms caused by prolonged viewing of the display area 21, this structure combines touch control and eye protection functions. The eye protection panel 100 includes an eye protection panel body 110 and a connecting structure 120. The mask frame 210 is mounted on the eye protection panel body 110. The eye protection panel body 110 is detachably connected to the frame edge 22 of the display area 21 on the display device through the connecting structure 120. This allows the eye protection panel body 110 to be quickly connected to display devices such as the computer 20 and to be quickly disassembled, simplifying the installation and removal process. It is convenient to use and can be applied to different non-touch display devices, making it widely applicable.

[0035] Specifically, the structure described in this embodiment is applied to display devices without touch functionality, such as computers 20, including but not limited to laptops 20 or desktop computers 20. The display device has a display area 21 and a frame 22. The frame 22 is located on the outer periphery of the display area 21. The eye protection panel 100 includes an eye protection panel body 110 and a connecting structure 120. The eye protection panel body 110 is connected to the frame 22 through the connecting structure 120, so that the eye protection panel body 110 is installed in the display area 21, thereby filtering blue light or ultraviolet light emitted by the display area 21 and reducing damage to the eyes. An infrared touch device 200 is connected to the side of the eye protection panel body 110 away from the display area 21, specifically including a mask frame 210 and an infrared touch component. The component is set inside the mask frame 210. The infrared touch component is electrically connected to the computer 20 and other devices via wires. The infrared touch component emits infrared rays toward the display area 21 to form a touch area. When a finger or other opaque object enters the touch area, some infrared rays on the touch area are blocked, so that some infrared receivers cannot receive infrared signals. Since the infrared touch component is electrically connected to the computer 20, the blocked infrared rays are detected inside the computer 20 and other devices, and the position of the touch point is calculated, thereby enabling the non-touch device to have touch function and realize human-computer interaction. The main body 110 of the eye protection panel can be made of acrylic material, which has high light transmittance and is relatively lightweight. It can also be made of polycarbonate, polystyrene, etc. There are no restrictions here.

[0036] Optionally, in an embodiment of this utility model, the mask frame 210 is screwed to the eye protection plate body 110. A bolt is provided, which passes through the mask frame 210 from the side away from the eye protection plate 100 and is screwed to the eye protection plate body 110. It should be noted that the mask frame 210 has a connecting hole, the eye protection plate body 110 has a threaded hole, and the bolt has a nut. When the bolt passes through the connecting hole and is connected to the threaded hole, the fastener is lower than or flush with the connecting hole. This not only avoids the mask frame 210 from protruding on one side and affecting the aesthetics, but also avoids the protruding structure affecting storage after the infrared touch device 200 is disassembled. Moreover, the screwed structure makes the connection between the mask frame 210 and the eye protection plate body 110 more stable.

[0037] Optionally, in one embodiment, a gasket is provided in the connection hole. The gasket may be made of nylon. When the bolt is passed through the connection hole and rotated to screw it into the threaded hole, the gasket can prevent damage to the mask frame 210 when the bolt is turned to tighten, and can also play a certain role in preventing loosening.

[0038] Optionally, in an embodiment of this utility model, the mask frame 210 is magnetically connected to the eye protection plate body 110. The mask frame 210 can be made of magnetic material. Due to the special nature of the material of the eye protection plate body 110, magnetic material cannot be used. Some ferromagnetic metal or magnetic material can be set on the edge of the eye protection plate body 110 to give it magnetic adsorption capability. That is, when the mask frame 210 and the eye protection plate body 110 are close, the mask frame 210 and the eye protection plate body 110 are magnetically connected. The magnetic connection between the mask frame 210 and the eye protection plate body 110 is more convenient and easier to disassemble. During the assembly and disassembly process, damage to the mask frame 210 or the eye protection plate body 110 can be reduced. It is also easier to adjust the relative position of the mask frame 210 and the eye protection plate body 110 to achieve better touch control and eye protection effect.

[0039] Optionally, in an embodiment of this utility model, the mask frame 210 is snapped into the eye protection plate body 110. A buckle protrudes outward from the eye protection plate body, the buckle including a first locking part connected to the eye protection plate body 110 and a second locking part connected to the first locking part, and the first locking part and the second locking part are bent and connected. A third locking part is provided at the end of the second locking part away from the first locking part and protruding towards the eye protection plate body 110. A slot is provided on the outside of the mask frame 210. When the mask frame 210 and the eye protection plate body 110 are brought close together and connected, the buckle is bent to deform it and the third locking part is engaged in the slot, thereby snapping the mask frame 210 and the eye protection plate body 110 together. The cooperation between the buckle and the slot can realize the quick installation and engagement of the mask frame 210 and the eye protection plate body 110, and can provide sufficient clamping force to ensure a tight connection and prevent loosening.

[0040] Optionally, in an embodiment of this utility model, the mask frame 210 is bonded to the eye protection plate body 110 by providing an adhesive between the mask frame 210 and the eye protection plate body 110. The adhesive can be double-sided tape or silicone sealant, or glue. It should be noted that before bonding, the edges of the mask frame 210 and the eye protection plate body 110 need to be cleaned to remove dust, oil, or other impurities, ensuring the surface is dry and improving the bonding effect. By bonding the mask frame 210 and the eye protection plate body 110, a stable connection is maintained.

[0041] In an embodiment of this utility model, the connecting structure 120 is configured as a hanging plate. The hanging plate is disposed on the top of the eye protection plate body 110 and is bent and connected to the eye protection plate body 110. The hanging plate extends in a direction away from the mask frame 210 to be hung on the top of the frame edge 22.

[0042] Specifically, such as Figure 3 and Figure 4 As shown, the mounting plate is bent and connected to the top of the eye protection panel body 110 and extends away from the mask frame 210. That is, the eye protection panel body 110 is hung on the frame edge 22 by the protruding mounting plate, thereby fixing the infrared touch device 200 to the display area 21. This not only filters blue light and ultraviolet light, but also allows the display area 21 to realize signal interaction through touch. Moreover, the mounting plate makes the connection with the computer 20 simpler and more convenient, simplifies the installation process, and reduces operation time.

[0043] Optionally, in one embodiment, the mounting plate and the main body 110 of the eye protection plate are integrally formed, such as by injection molding, without limitation. This can reduce the number of parts and assembly steps, reduce the cost of the eye protection plate 100, improve the stability of the eye protection plate 100, make the eye protection plate 100 smoother, and improve the eye protection effect.

[0044] In an embodiment of this utility model, the connecting structure 120 is configured as a first magnetic member and a second magnetic member. The first magnetic member is located on the edge of the eye protection panel body 110 away from the infrared touch device 200, and the second magnetic member is located on the frame edge 22. The first magnetic member and the second magnetic member are magnetically connected to connect the eye protection panel body 110 and the display area 21 of the computer 20. The first magnetic member and the second magnetic member can be configured as magnetic materials, and the magnetic materials are respectively bonded to the frame edge 22 and the frame of the eye protection panel body 110 by adhesive. When the eye protection panel body 110 is close to the display area 21 of the computer 20, the first magnetic member and the second magnetic member are magnetically attracted, and the eye protection panel body 110 is magnetically attracted to the display device of the computer 20, realizing the detachable connection between the eye protection panel 100 and the computer 20. The installation method is simple and can achieve quick assembly and disassembly.

[0045] In an embodiment of this utility model, the connecting structure 120 is configured as a snap-fit ​​part, which is used to elastically snap-fit ​​with the frame edge 22. The snap-fit ​​part protrudes from the side frame of the eye protection panel body 110 and extends toward the side away from the infrared touch device 200. A hook body is hooked inward on the side of the snap-fit ​​part away from the eye protection panel body 110. When the eye protection panel body 110 is installed on the display area 21, the hook body is used to snap-fit ​​the rear side of the frame edge 22 of the computer 20 display screen to connect the eye protection panel body 110 and the computer 20 display screen, so that the computer 20 has infrared touch and eye protection functions.

[0046] In embodiments of this utility model, such as Figure 4 As shown, the mask frame 210 has a hollow area in the middle. The mask frame 210 includes a front shell and a rear shell, which together form an accommodating cavity. The infrared touch component is disposed in the accommodating cavity, and the rear shell is fitted to the eye protection panel body 110. The shape of the mask frame 210 is the same as the shape of the frame of the eye protection panel body 110. The hollow area in the middle of the mask frame 210 corresponds to the display area 21. Common display devices are rectangular, so the mask frame 210 can be understood as a rectangular frame with a hollow center. The mask frame 210 includes a front shell and a rear shell. The front shell is disposed away from the eye protection panel 100, and the rear shell is disposed close to the eye protection panel 100 and fitted to the eye protection panel body 110. The connection can be made by adhesive, magnetic attraction, or screwing, etc., without limitation. The front shell and the rear shell are connected to form an accommodating cavity, which facilitates the thinning of the module. The front shell and the rear shell can be connected by magnetic attraction, embedding, etc., without limitation. The infrared touch component is set in the accommodating cavity, and infrared light can be emitted towards the center position through the infrared touch component in the mask frame 210. It should be noted that the position of the front shell / rear shell / or the connection between the front shell and the rear shell facing the hollow area is set as a light-transmitting part. This can not only make use of the accommodating cavity to reasonably install the infrared touch component and reduce the size of the touch device, but also ensure that the infrared light emitted by the infrared touch component can pass through the light-transmitting part and be emitted towards the hollow area to achieve the touch effect.

[0047] In embodiments of this utility model, such as Figure 4 As shown, the infrared touch component includes a circuit board, an infrared filter strip 220, and multiple infrared probes. One side of the circuit board is attached to the back cover, and the other side is electrically connected to the infrared probes. The infrared filter strip 220 is positioned towards the hollow area, and the infrared probes are positioned towards the infrared filter strip 220 to transmit infrared light towards the hollow area.

[0048] Specifically, the circuit board is installed inside the accommodating cavity and is positioned opposite and spaced apart from the rear shell. The space between the circuit board and the front shell is defined for the installation of the infrared probe, ensuring that the infrared probe can be stably installed and work normally. The infrared filter strip 220 is installed on the side of the front shell facing the hollow area, and the front shell faces the hollow area to facilitate the infrared light emitted by the infrared probe to pass through the infrared filter strip 220. In addition to the infrared probe, an infrared receiver tube is also installed inside the accommodating cavity. The circuit board is electrically connected to the infrared probe and the infrared receiver tube, driving the infrared probe to emit infrared light and simultaneously receiving the signal from the infrared receiver tube. When an object touches the screen, it blocks the infrared light at that location. The infrared receiver tube detects the change in light and thus determines the touch position, achieving the touch control effect.

[0049] Optionally, in one embodiment, the infrared filter strip 220 may be made of silicon glass, quartz glass, soda glass, potassium glass, polycarbonate or polyimide, etc., and there are no restrictions on the material.

[0050] In the embodiments of this utility model, please refer to Figure 1 A communication interface 211 electrically connected to the circuit board is provided on one side of the mask frame. The communication interface 211 is electrically connected to the computer 20 via a transmission line 300. The communication interface 211 is magnetically connected to the transmission line 300, that is, one end of the transmission line 300 is magnetically connected to the communication interface 211, and the other end is plugged into the computer 20, so that the computer 20 and other devices have touch function, which is simple and convenient to operate. There is no need for manual alignment. Automatic connection can be completed simply by approaching. The connection is stable and ensures the smoothness and accuracy of the touch function.

[0051] In one embodiment, the other end of the transmission line 300 is configured with a Type-C interface, which is small in size and relatively thin. Of course, the other end of the transmission line is not limited to a Type-C port, and can also use a Type-A interface or a USB interface.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
