For example, an infrared touch screen may include a plurality of infrared lamp tubes distributed on the border of the touch screen. The infrared lamp tube may include an infrared emitting tube and an infrared receiving tube. The infrared emitting tube emits an infrared light signal under the control of a controller. The corresponding infrared receiving tube can receive the infrared light signal and convert it into an electrical signal. After processing such as amplifying and gain adjusting the converted electrical signal, the controller is used to collect and process the adjusted electrical signal, and determine whether the infrared light is blocked by a touch object by detecting the change of the electrical signal, so as to realize touch functions such as clicking, drawing lines, and touching.

In the traditional technology, due to the structural limitation of the infrared lamp tube used in the infrared touch screen, its effective working angle is small, resulting in limited density and intensity of the light network formed in the infrared touch screen, which affects the touch performance of the infrared touch screen. Summary of the Utility Model

Detailed implementation manners

[0042] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] In many electronic devices, an infrared lamp tube structure is provided. The infrared lamp tube structure may include an infrared emitter and an infrared receiver. The infrared lamp tube structure can be used in various application scenarios such as touch, remote control, security monitoring, and intelligent home.

[0044] In the present invention, the infrared lamp tube structure can be applied to an infrared touch screen. In the infrared touch screen, by arranging a plurality of infrared emitters and a plurality of infrared receivers on the four peripheral frames of the touch screen outer frame, controlling the infrared emitters to emit infrared light signals, and controlling the infrared receivers to receive infrared light signals, and then calculating whether a touch operation occurs according to the changes in the infrared light signals received by each infrared receiver.

[0045] Such as Figures 1 to 5As shown in the figure, the present utility model provides an infrared lamp tube structure 10, which includes a base 100, a light-emitting component 200 disposed on the base 100, and a lamp cover structure 300 disposed on the base 100. The lamp cover structure 300 covers the light-emitting component 200. The infrared lamp tube structure 10 can be disposed on the border circuit board of the four peripheral borders of the outer frame of the touch screen through the base 100, so that the light-emitting component 200 is connected to the border circuit board. Moreover, the light-emitting component 200 can emit or receive infrared light signals through the lamp cover structure 300. Among them, the setting method of the lamp cover structure 300 will affect the effective working angle of the infrared lamp tube structure 10, that is, it can affect the effective emission angle of the infrared emitter emitting infrared light signals and the effective reception angle of the infrared receiver receiving infrared light signals.

[0046] Specifically, the lamp cover structure 300 may include a lamp cover base 310 disposed on the base 100, and an outer cover body 320 disposed on the lamp cover base 310. Moreover, the outer cover body 320 may include a first cover body 322 and a second cover body 324 disposed on the lamp cover base 310, and a cover body connecting portion 326 connecting the first cover body 322 and the second cover body 324. Moreover, the first cover body 322, the second cover body 324, and the cover body connecting portion 326 cover the outside of the light-emitting component 200, and the first cover body 322, the second cover body 324, and the cover body connecting portion 326 can all be set as arc-shaped lenses. The effective working angle of the infrared lamp tube structure 10 is usually determined by its lens structure (that is, the lamp cover structure 300). By setting a cover body structure composed of cover body parts such as the first cover body 322, the cover body connecting portion 326, and the second cover body 324 on the light-emitting component 200, the cover body structure formed by a traditional single cover body part is expanded, the effective light-transmitting area of the cover body structure is increased, thereby increasing the effective working angle of the infrared lamp tube structure 10, and the density and intensity of the light network formed when this infrared lamp tube structure 10 is applied to an infrared touch screen can be increased, thereby enhancing the touch performance of the infrared touch screen.

[0047] In addition, in an embodiment, when the light-emitting component 200 of the infrared lamp tube structure 10 is working, the intensity of the infrared light signals transmitted through the first cover body 322 and the second cover body 324 is greater than or equal to the intensity of the infrared light signals transmitted through the cover body connecting portion 326. By designing the lens structures of the first cover body 322, the second cover body 324, and the cover body connecting portion 326, and designing the structure of the light-emitting component 200, the light-transmitting intensity of the first cover body 322 and the second cover body 324 can be made greater than or equal to the light-transmitting intensity of the cover body connecting portion 326, so that the parts on the outer side of the middle part of the infrared lamp tube structure 10 (the outer sides of the first cover body 322 and the second cover body 324 where the cover body connecting portion 326 is located in the middle) have stronger light-transmitting performance, so as to increase the light intensity of the infrared lamp tube structure 10.

[0048] Moreover, in one embodiment, when the light-emitting component 200 of the infrared lamp tube structure 10 is operating, the intensity distributions of the infrared light signals transmitted through the first cover 322 and the second cover 324 are the same. That is, by making the structures of the first cover 322 and the second cover 324 the same, and at the same time making the effects of the light-emitting component 200 on the first cover 322 and the second cover 324 the same, each part on the first cover 322 and the second cover 324 can have the same light-transmitting performance, making the infrared lamp tube structure 10 have uniform light transmission.

[0049] In addition, as Figures 3 to 5 shown, the lamp cover structure 300 of the infrared lamp tube structure 10 may include one or more first covers 322, one or more second covers 324, and one or more cover connection parts 326. As needed, the effective working angle and light intensity of the infrared lamp tube structure 10 can be increased in all directions.

[0050] In addition, as Figure 4 shown, in one embodiment, the light-emitting component 200 may include a first light-emitting chip 210 disposed in the middle of the lamp cover base 310, and the cover connection part 326 may correspondingly cover the outside of the first light-emitting chip 210. In this embodiment, only one light-emitting chip (or light-emitting wafer) may be disposed in the middle of the lamp cover base 310, for emitting or receiving infrared light signals. Moreover, when the first light-emitting chip 210 is operating, it can transmit or receive infrared light signals through the first cover 322, the cover connection part 326, and the second cover 324.

[0051] In addition, as Figure 3 shown, in another embodiment, the light-emitting component 200 may include a second light-emitting chip 220 and a third light-emitting chip 230 disposed on the lamp cover base 310. The first cover 322 correspondingly covers the outside of the second light-emitting chip 220, and the second cover 324 correspondingly covers the outside of the third light-emitting chip 230. In this embodiment, one light-emitting chip (or light-emitting wafer) may be disposed on each side of the lamp cover base 310, respectively for emitting or receiving infrared light signals from both sides. Moreover, when the two light-emitting chips are operating, they can transmit or receive infrared light signals through the first cover 322, the cover connection part 326, and the second cover 324.

[0052] In addition, as Figure 5As shown, in another embodiment, the light-emitting member 200 may include a first light-emitting chip 210 disposed in the middle of the lamp cover base 310, and the cover body connecting portion 326 may correspondingly cover the outside of the first light-emitting chip 210; moreover, the light-emitting member 200 may include a second light-emitting chip 220 and a third light-emitting chip 230 disposed on the lamp cover base 310, and the first cover body 322 correspondingly covers the outside of the second light-emitting chip 220, and the second cover body 324 correspondingly covers the outside of the third light-emitting chip 230. In this embodiment, one light-emitting chip (or light-emitting wafer) may be provided on each of the two sides and the middle of the lamp cover base 310, respectively, for emitting or receiving infrared light signals from the middle and both sides.

[0053] Moreover, as Figures 2 to 12 shown, in one embodiment, the first cover body 322 and the second cover body 324 of the lamp cover structure 300 may be symmetrically arranged with respect to the cover body connecting portion 326. This can not only make the appearance of the infrared lamp tube structure 10 beautiful, but also enable the first cover body 322 and the second cover body 324 to have the same or similar optical properties, so as to maximize the effective working angle of the infrared lamp tube structure 10.

[0054] Furthermore, as Figures 2 to 10 shown, in one embodiment, the outer cover body 320 may be arranged in an M shape, that is, the first cover body 322 and the second cover body 324 may respectively protrude from both sides of the cover body connecting portion 326, so that the outer cover body 320 presents a shape with higher heights on both sides and a lower height in the middle.

[0055] In addition, as Figures 11 to 12 shown, in another embodiment, the outer cover body 320 may be arranged in a semi-elliptical shape. That is, the first cover body 322, the second cover body 324 and the cover body connecting portion 326 may be smoothly and transitionally connected, so that the outer cover body 320 as a whole presents a semi-elliptical structure or a structure similar to a semi-elliptical shape.

[0056] Moreover, as Figures 2 to 10 shown, the cover body connecting portion 326 may be completely separated between the first cover body 322 and the second cover body 324, that is, the first cover body 322 and the second cover body 324 may be completely separated by the cover body connecting portion 326. In addition, as Figures 11 to 12 shown, the cover body connecting portion 326 may also be partially separated between the first cover body 322 and the second cover body 324, that is, the first cover body 322 and the second cover body 324 may be partially separated by the cover body connecting portion 326, and the first cover body 322 and the second cover body 324 still have a part directly connected.

[0057] Moreover, as Figures 2 to 5 shown, the width of the cover body connecting portion 326 may be relatively large, which can significantly space the first cover body 322 and the second cover body 324; in addition, as Figures 5 to 9As shown, the width of the cover body connecting portion 326 can also be zero (or close to zero), which can make the cover body connecting portion 326 form a part of the first cover body 322 or / and the second cover body 324.

[0058] In addition, as Figure 2 , Figure 6 , Figure 8 , Figure 9 , Figure 12 shown, in one embodiment, the outer circumferential surface of the lamp shade base 310 can be an arc-shaped toroidal surface. That is, the outer circumferential surface of the lamp shade base 310 can be a smooth arc-shaped toroidal surface, such as an elliptical toroidal surface, which has a beautiful appearance.

[0059] In addition, as Figure 7 , Figure 10 , Figure 11 shown, in one embodiment, the outer circumferential surface of the lamp shade base 310 is a multi-segment toroidal surface. That is, the outer circumferential surface of the lamp shade base 310 can be a toroidal surface composed of multiple arc-shaped surfaces or / and multiple planar surfaces.

[0060] In addition, as Figure 7 , Figure 10 shown, in one embodiment, the four peripheral edges of the projection surface of the outer cover body 320 on the top surface of the lamp shade base 310 are located within the four peripheral edges of the top surface of the lamp shade base 310. That is, the outer side surfaces of the first cover body 322, the second cover body 324, and the cover body connecting portion 326 are all located inside the four peripheral edges of the top surface of the lamp shade base 310.

[0061] In addition, as Figure 2 , Figure 6 , Figure 8 , Figure 9 , Figure 11 , Figure 12 shown, in one embodiment, at least part of the four peripheral edges of the projection surface of the outer cover body 320 on the top surface of the lamp shade base 310 coincides with the four peripheral edges of the top surface of the lamp shade base 310. That is, part or all of the outer side surfaces of the first cover body 322, the second cover body 324, and the cover body connecting portion 326 are aligned with the four side surfaces of the lamp shade base 310. Moreover, part or all of the outer side surfaces of the first cover body 322, the second cover body 324, and the cover body connecting portion 326 can protrude beyond the four side surfaces of the lamp shade base 310.

[0062] Moreover, the intersection line of the bottom surface of the outer cover 320 and the top surface of the lamp holder 310 can be located inside the four peripheral edges of the top surface of the lamp holder 310, that is, the bottom surface of the outer cover 320 is completely located inside the four peripheral edges of the top surface of the lamp holder 310; or, the intersection line of the bottom surface of the outer cover 320 and the top surface of the lamp holder 310 is at least partially located on the four peripheral edges of the top surface of the lamp holder 310, that is, at least part of the four peripheral edges of the bottom surface of the outer cover 320 coincides with the four peripheral edges of the top surface of the lamp holder 310, which can make the two be at least partially smoothly transitionally connected; or, the intersection line of the bottom surface of the outer cover 320 and the top surface of the lamp holder 310 is at least partially located outside the four peripheral edges of the top surface of the lamp holder 310, that is, at least part of the four peripheral edges of the bottom surface of the outer cover 320 protrudes outside the four peripheral edges of the top surface of the lamp holder 310.

[0063] In addition, the present utility model also provides an infrared touch screen, which includes a touch screen outer frame and an infrared lamp tube structure 10 disposed on the touch screen outer frame. Specifically, the substrate of the infrared lamp tube structure 10 can be disposed on the outer frame circuit board of the touch screen outer frame.
