DETAILED DESCRIPTION

[0028] The following is a detailed explanation of the implementation of the present invention in conjunction with the accompanying drawings. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention.

[0029] Reference Figures 1 to 8 An infrared remote controller for increasing the emission angle and distance includes a remote control body 51, a main control board 5 and a lens 8. The main control board 5 is accommodated in the remote control body 51. An infrared emitting tube 7 is electrically connected to the main control board 5. A emitting port 511 is provided on the top of the remote control body 51. The infrared emitting tube 7 is located at the emitting port 511. The lens 8 is covered on the emitting port 511. The infrared emitting tube 7 points to the lens 8. The light incident side of the lens 8 is coaxially provided with a plurality of circles of protrusions 84 to form a focusing surface. The light emitting side of the lens 8 is arc-shaped and concave to form a light diffusion surface 82.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The remote control body 51 includes a shell 1, a panel 4, a key control board 6 and a keyboard 61. The panel 4 and the shell 1 are both in the shape of a long shell. A first card slot 11 is provided on the top inner wall of the shell 1, and a second card slot 41 is provided on the top inner wall of the panel 4. The second card slot 41 corresponds to the position of the first card slot 11. When the panel 4 is covered with the shell 1, the first card slot 41 and the second card slot 11 are connected to form an annular groove. The panel 4 is covered on the shell 1 to form a cavity. The transmitting port 511 is located at the top of the cavity. The main control board 5 and the key control board 6 are both located in the cavity. The keyboard 61 and the key control board 6 are sequentially stacked on the main control board 5 from the outside to the inside. Each key 62 of the keyboard 61 is exposed on the panel 4, and the key control board 6 is electrically connected to the main control board 5.

[0031] Reference Figure 2 and Figure 3 A rear cover 3 is provided on the back of the shell 1 , and the rear cover 3 is covered on the shell 1 to form a battery compartment. The battery compartment contains two batteries 2 , and both batteries 2 are electrically connected to the main control board 5 .

[0032] Reference Figure 4 , Figure 5 and Figure 6 The lens 8 is elliptical, and a circle of card platform 81 is provided at the edge of the lens 8. The two ends of the card platform 81 are respectively engaged with the first card slot 11 and the second card slot 41 in a one-to-one manner, so as to clamp the entire lens 8 between the shell 1 and the panel 4. A focusing groove 83 is provided on the light incident side of the lens 8. The bottom of the focusing groove 83 constitutes the focusing surface. The focusing surface is arranged in an arc-shaped concave shape. All protrusions 84 are eccentrically arranged on the focusing surface of the lens 8. All protrusions 84 are serrated. Two adjacent circles of protrusions 84 are connected to each other. Each circle of protrusions 84 is inclined to its inner side. All protrusions 84 are coaxially arranged with the infrared emitting tube 7. The number, spacing and shape of the protrusions 84 affect the performance of the lens 8. The more protrusions 84 there are, the denser the focusing surface, the larger the infrared emission angle, and the longer the focal length; the deeper the protrusions 84 are engraved, the longer the sensing distance is, and the closer the focal length is. The infrared emitting tube 7 is vertically pointed to the lens 8 and its top extends into the focusing groove 83.

[0033] Reference Figure 7 and Figure 8 The working principle of the infrared remote control with increased emission angle and distance of the utility model is as follows: the infrared light emitting point 71 of the infrared emitting tube 7 emits infrared light, the infrared light is emitted to the focusing surface of the lens 8, and then enters the lens 8 after being focused by multiple circles of serrated protrusions 84, and then refracted by the astigmatism surface 82 of the lens 8, and evenly scattered to form a larger emission angle, thereby increasing the infrared remote control emission distance and angle, and improving the user's operating flexibility and convenience.

[0034] Reference Figure 7 and Figure 8 In the infrared remote controller with increased emission angle and distance of the utility model, the lens 8 can gather infrared light and then diffuse the infrared light, thereby increasing the emission distance and angle of the infrared remote control device, and the emission angle b of the remote controller can be increased to about 50 degrees (such as Figure 8 As shown), the transmission distance a between the remote control and the receiving device 9 is increased to about 10m, which solves the problems of small angle and short distance in the prior art without increasing the cost.

[0035] The infrared remote controller of the utility model with increased emission angle and distance cleverly utilizes the optical characteristics of the lens 8 and realizes the gathering and diffusion of infrared light through a special structural design. Specifically, the utility model is provided with a specially designed lens 8 at the emission port 511 of the remote control body 51, and the light-incoming side of the lens 8 is coaxially provided with a plurality of circles of protrusions 84, which together constitute a focusing surface, which can effectively converge the infrared light emitted by the infrared emission tube 7, and enhance the directionality and penetration of the light. At the same time, the light-emitting side of the lens 8 is designed as an arc-shaped concave diffuser surface 82, and when the converged light reaches this surface, it will be evenly scattered to form a larger emission angle. Through this design, the utility model not only solves the problems of small emission angle and short distance of the existing infrared remote controller without increasing the cost, but also improves the transmission efficiency and coverage of the infrared signal, bringing users a more convenient and efficient remote control experience. In addition, the design also has high reliability and stability, and can be applied to a variety of different usage scenarios and needs, injecting new vitality into the development of infrared remote controllers.

[0036] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
