Description

Technical Field

[0001] This invention relates to the field of infrared touch display device technology, and in particular to a frame assembly for an infrared touch screen and an infrared touch screen. Background Technology

[0002] Currently, infrared touch display devices with touch functionality are widely used in industries such as education, commercial advertising, film and entertainment, healthcare, tourism, and artificial intelligence simulation. In existing technologies, infrared touch display devices are formed by assembling separate infrared touchscreen products and separate display products together.

[0003] A traditional infrared touchscreen includes a frame assembly 1 and a backlight module (not shown). The frame assembly 1 includes a front frame 10, a touch frame 20, and a glass panel 30. The front frame 10 is a frame-like structure formed by splicing several frame pieces. The glass panel 30 is confined within the frame pieces. A receiving groove 50 is formed within the frame pieces, and the touch frame 20 is disposed within the receiving groove 50 of the frame pieces. Please refer to... Figure 1-3 , Figure 1 This is a front view of the infrared touchscreen structure described in the prior art. Figure 2 This is a schematic diagram of a partial structure angle of an infrared touchscreen as described in the prior art. Figure 3 This is a schematic diagram of a partial structure of the infrared touchscreen described in the prior art from a second angle. Because there is a gap between the glass panel 30 and the front frame 10, water droplets accidentally splashed during use, or water droplets formed by condensation on the glass panel during humid weather in southern regions, as shown in Figure 4, can easily seep into the frame assembly through the gap. Figure 1-3 As shown by the middle arrow, this can affect the components of the touch frame 20 and the backlight module, and even cause the profile to rust, leading to problems such as the failure of the touch function of the whole machine. Summary of the Invention

[0004] Based on this, the purpose of this invention is to provide a frame assembly for an infrared touch screen, which has the advantages of simple structure, low cost and effective prevention of water ingress and rust.

[0005] The embodiments of the present invention achieve the above objectives through the following technical solutions:

[0006] An infrared touchscreen bezel assembly includes a front frame, a touch frame, and a glass panel. The front frame has a frame-like structure, comprising several frame bodies and several corner connectors, with adjacent frame bodies detachably joined at their ends via the corner connectors. The touch frame is disposed within the frame body. The glass panel is embedded and confined within the front frame at its four edges. Each frame body includes a first surface and a second surface. The first surface extends along the length of the frame body, is perpendicular to the glass panel, and abuts against the edge of the glass panel. The second surface is parallel to the glass panel and located inside the glass panel. The frame body is provided with drainage channels, including a first drainage channel and a second drainage channel. The first drainage channel is located on the first surface, extends along the length of the frame body, and corresponds to the edge of the glass panel. The second drainage channel is located on the second surface, with one end connected to the first drainage channel and the other end connected to the outside of the infrared touchscreen.

[0007] The frame has a receiving groove along its length, and the touch frame is disposed in the receiving groove. The touch frame includes a plurality of infrared filter strips, which are disposed at the opening of the receiving groove.

[0008] The infrared touchscreen frame assembly described in this invention features a drainage channel on the frame. The first drainage channel corresponds to the edge of the glass panel. When water droplets formed on the outer surface of the glass panel due to damp weather or other conditions condense and seep into the gap between the glass panel and the front frame, the water flows along the first drainage channel and then further flows out through the second drainage channel to the outside of the device. This effectively prevents water droplets from crossing the frame assembly and entering the interior of the infrared touchscreen structure, thus preventing rust or affecting the normal function of other components. By directly creating drainage channels on the frame, the problem of water ingress and rusting of the infrared touchscreen is effectively solved, with excellent results, a simple structure, and low modification costs.

[0009] Furthermore, the frame includes a bottom frame, a top frame, a first side frame, and a second side frame. Both the first surface and the second surface are located on the bottom frame, and the second drainage channel extends vertically. The drainage channel on the bottom frame allows water droplets condensing on the outer surface of the glass panel when the infrared touchscreen is wall-mounted or placed vertically to fall along the glass panel surface under their own weight. The water then seeps into the first drainage channel through the gap between the glass panel and the frame, flows further along the first drainage channel, and quickly flows out of the device through the vertically extending second drainage channel, preventing water from accumulating in the drainage channel.

[0010] Furthermore, the connection point between the first drainage channel and the second drainage channel is the point where the depth of the first drainage channel is greatest. By utilizing the change in the depth of the first drainage channel, the flow direction of the liquid in the channel is limited, which helps to drain the water accumulated in the first drainage channel as quickly as possible and avoids problems such as prolonged liquid residue causing rusting of the frame profile or the growth of microorganisms and the generation of odors.

[0011] Furthermore, the number of the second drainage channels is at least two, which further promotes the rapid drainage of water accumulated in the first drainage channel.

[0012] Furthermore, the frame includes a pressing part and a frame body. Both the pressing part and the frame body extend along the length direction of the frame body, and the pressing part abuts against the edge of the outer surface of the glass panel. The frame body is vertically fixed to the pressing part. The pressing part and the frame body are used to limit the glass panel in various directions. The first surface and the second surface are both located on the frame body.

[0013] Furthermore, the opening of the receiving groove is located in the pressing part, and the receiving groove openings of the two opposing frames are arranged facing each other; the touch frame is disposed in the receiving groove.

[0014] Furthermore, the touch frame includes an infrared transmitter and an infrared receiver. The infrared transmitter is disposed in at least one receiving groove of the frame, and the infrared receiver is disposed opposite to the infrared transmitter to realize the touch function.

[0015] In addition, embodiments of the present invention also provide an infrared touch screen, which includes the above-described infrared touch screen bezel assembly.

[0016] The infrared touch screen described in this embodiment of the invention, through the structural design of the frame component, can prevent external liquids from flowing into the interior of the touch screen structure, thereby preventing rust or poor touch performance. It has a simple structure and low cost.

[0017] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0027] Example 1

[0028] Please refer to Figure 4-6 , Figure 4 This is a schematic diagram of the frame assembly structure for the infrared touchscreen described in Embodiment 1 of the present invention. Figure 5 This is a partial structural diagram of the frame assembly for the infrared touchscreen described in Embodiment 1 of the present invention. Figure 6This is a schematic diagram of the drainage trough structure described in Embodiment 1 of the present invention. Embodiment 1 of the present invention provides a frame assembly for an infrared touch screen, which includes a front frame 10, a touch frame 20, and a glass panel 30. The front frame 10 has a frame-like structure, which includes several frame bodies and several corner connectors 17. The ends of two adjacent frame bodies are detachably spliced ​​through the corner connectors 17. The touch frame 20 is disposed in the frame body. The glass panel 30 is embedded and limited in the front frame 10 at its four edges. The frame body includes a first surface 11 and a second surface 12. The first surface 11 is along the length direction of the frame body. The frame is provided with a drainage channel 40, which is perpendicular to the glass panel 30 and abuts against the edge of the glass panel 30. The second surface 12 is parallel to the glass panel 30 and located inside the glass panel 30. The frame is provided with a drainage channel 40, which includes a first drainage channel 41 and a second drainage channel 42. The first drainage channel 41 is located on the first surface 11, which extends along the length of the frame and corresponds to the edge of the glass panel 30. The second drainage channel 42 is located on the second surface 12, with one end connected to the first drainage channel 41 and the other end connected to the outside of the infrared touch screen.

[0029] The infrared touchscreen frame assembly described in Embodiment 1 of this invention features a drainage channel on the frame. The first drainage channel corresponds to the edge of the glass panel. When water droplets formed on the outer surface of the glass panel due to damp weather or other conditions condense and seep into the gap between the glass panel and the front frame, the water flows along the first drainage channel and then further flows out through the second drainage channel to the outside of the device. This effectively prevents water droplets from crossing the frame assembly and entering the interior of the infrared touchscreen structure, thus preventing rusting or affecting the normal function of other components. By directly creating drainage channels on the frame, the problem of water ingress and rusting of the infrared touchscreen is effectively solved, with excellent results, a simple structure, and low modification costs.

[0030] It should be noted that when the infrared touch screen frame assembly is assembled with other structural components to form the infrared touch screen overall structure, the inner and outer sides of the glass panel mentioned in the description of the embodiments of the present invention refer to the inner and outer sides of the glass panel relative to the overall structure, and the inner and outer surfaces of the glass panel refer to the two opposite surfaces of the glass panel facing the inner and outer sides of the overall structure, respectively.

[0031] As an optional implementation, in this embodiment, the number of frames is 4, including a bottom frame 13, a top frame 14, a first side frame 15, and a second side frame 16, and the number of corner connectors 17 is also 4. Specifically, in this embodiment, the frame includes a pressing part 18 and a frame body 19. Both the pressing part 18 and the frame body 19 extend along the length direction of the frame. The pressing part 18 abuts against the outer edge of the glass panel 30, and the frame body 19 is vertically fixed to the pressing part 18 to limit the glass panel 30. The first surface 11 and the second surface 12 are both located on the frame body 19 of the bottom frame 13.

[0032] A drainage groove 40 is provided on the bottom frame 13 so that when the infrared touch screen is wall-mounted or placed vertically, the water droplets condensed on the outer surface of the glass panel 30 can fall down along the surface of the glass panel 30 under their own weight. They seep into the first drainage groove 41 through the gap between the glass panel 30 and the bottom frame 13 and then flow along the first drainage groove 41 to prevent them from entering the interior of the infrared touch screen structure. More preferably, the second drainage groove 42 extends vertically so that the water droplets in the second drainage groove 42 can flow out of the device quickly, preventing them from accumulating in the drainage groove and causing the profile and touch frame 20 to rust and affect the normal touch function of the touch frame 20.

[0033] As an optional implementation, in this embodiment, the connection point between the first drainage channel 41 and the second drainage channel 42 is the point where the depth of the first drainage channel 41 is greatest. By utilizing the change in depth of the first drainage channel 41, the flow direction of the liquid within the drainage channel 40 is defined, which helps to quickly drain the water accumulated in the first drainage channel 41 and avoids problems such as prolonged liquid residue causing rusting of the frame profile or the growth of microorganisms and the generation of odors. More preferably, the number of second drainage channels 42 is at least two, located at both ends of the second drainage channel, to further promote the rapid drainage of water accumulated in the first drainage channel 41.

[0034] As an optional implementation, in this embodiment, the frame is provided with a receiving groove 50 along its length direction. The opening of the receiving groove 50 is located in the pressing part 18, and the openings of the receiving grooves 50 of the two opposing frames are arranged facing each other. Specifically, in this embodiment, the openings of the receiving grooves 50 of the upper frame 14 and the lower frame 13 are arranged facing each other, that is, the opening of the receiving groove 50 of the upper frame 14 is arranged facing the lower frame 13, and the opening of the receiving groove 50 of the lower frame 13 is arranged facing the upper frame 14. The touch frame 20 is disposed within the receiving groove 50. The touch frame 20 includes an infrared emitting device, an infrared receiving device, and an infrared filter strip. The infrared emitting device is disposed at least outside the edge of one side of the glass panel 30, that is, at least within the receiving groove 50 of one of the frames. The infrared receiving device is disposed opposite to the infrared emitting device. The infrared filter strip is disposed at the opening of the receiving groove 50. Specifically, in this embodiment, the infrared emitting device may be disposed within the receiving groove 50 of the bottom frame 13, and correspondingly, the infrared receiving device may be disposed within the receiving groove 50 of the top frame 14. The specific positions of the infrared emitting device and the infrared receiving device, as well as the opening of the receiving groove 50, enable the infrared signal emitted by the infrared emitting device to move along the outer surface of the glass panel 30 and smoothly enter the receiving groove 50 for reception by the infrared receiving device, thereby realizing the touch function.

[0035] The infrared touchscreen frame assembly described in Embodiment 1 of this invention features a drainage channel on the frame. In a preferred embodiment, the structure of the drainage channel is further optimized. The first drainage channel corresponds to the edge of the glass panel. When water droplets formed on the outer surface of the glass panel due to damp weather or other conditions condense and seep into the gap between the glass panel and the front frame, they flow directionally along the first drainage channel and then flow out through the second drainage channel to the outside of the device. This effectively prevents water droplets from crossing the frame assembly and entering the interior of the infrared touchscreen structure, thus preventing rust or affecting the normal function of other components. By directly creating drainage channels on the frame, the problem of water ingress and rusting of the infrared touchscreen is effectively solved, resulting in excellent performance, a simple structure, and low modification costs.

Embodiment 2 of the present invention provides an infrared touch screen, which includes the frame assembly for the infrared touch screen described in Embodiment 1.

[0038] The infrared touch screen described in this embodiment of the invention, through the structural design of the frame component, can prevent external liquids from flowing into the interior of the touch screen structure, thereby preventing rust or poor touch performance. It has a simple structure and low cost.

[0039] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
