[0033] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] It should be understood that:

[0035] In traditional set-top boxes / convergent terminal products, a separate infrared window is fixed to the main housing by heat melting or snapping. The large number of structural parts leads to high mold opening and assembly costs.

[0036] A further solution is to use an integrated infrared semi-transparent main shell, which can eliminate the need for a separate infrared window. However, since the entire shell is semi-transparent, a sunshade or light-shielding foam will be introduced, and the cost investment is also relatively high.

[0037] Therefore, the problem we face is how to simplify the structure, reduce costs and ensure the infrared reception effect.

[0038] The embodiments of the present application provide an infrared-transmitting housing and an infrared-transmitting communication device to solve the problems in the related art of complex structures of a separate infrared window box and a main shell, and high costs caused by the introduction of a light-shielding cover or light-shielding foam into the entire semi-transparent housing.

[0039] First, see Figure 2 、 Figure 3 and Figure 4 , an infrared-transmitting housing comprising:

[0040] The shell body 1 has a window area 3 on its outer periphery, in which the infrared receiving head 2 is arranged;

[0041] A vertical window 4 is provided in the window opening area 3 and is provided with horizontal windows 5 located in the window opening area 3 on both sides thereof in the horizontal direction;

[0042] Vertically, the receiving area is located between the top and bottom of the vertical window 4; horizontally, the receiving area is located between the two side edges; the side edge is the side of the horizontal window 5 away from the vertical window 4; the receiving area is the working area of ​​the infrared receiving head 2 for receiving infrared.

[0043] Among them, the understanding of the receiving area can be understood as follows: the infrared receiving head 2 is located in the shell body 1 and corresponds to the center of the vertical window 4; Figure 4 , the receiving angle of the infrared receiving head 2 in the vertical direction is less than or equal to the angle between the first connecting line and the second connecting line; the first connecting line and the second connecting line are respectively the connecting lines between the infrared receiving head 2 and the top and bottom of the vertical window 4; Figure 3 , the horizontal receiving angle is less than or equal to the angle between the third line and the fourth line; the third line and the second line are respectively the lines between the infrared receiving head 2 and the two horizontal windows 5 away from the side of the vertical window 4.

[0044] In the above structure, the vertical window 4 is arranged in the window opening area 3 of the shell body 1, and horizontal windows 5 are provided on both sides in the window opening area 3. This arrangement can meet the characteristics of actual infrared reception in the up and down directions and the left and right directions; in addition, in the vertical direction, the receiving area is located between the top and bottom of the vertical window 4; in the horizontal direction, the receiving area is located between the two side edges; the side edge is the side of the horizontal window 5 away from the vertical window 4; the above arrangement realizes that the window that can transmit infrared rays can cover the infrared receiving working area of ​​the infrared receiving head 2, ensuring that the infrared rays will not be blocked and the receiving effect is guaranteed. In addition, the above infrared window structure is integrated with the shell body 1, thereby simplifying the structure, reducing costs while ensuring the infrared receiving effect.

[0045] In some preferred embodiments, in order to achieve the maximum effect that the infrared window does not block the working area of ​​the infrared receiving head 2 receiving infrared, the following settings are also provided:

[0046] In the vertical direction, the distance between the top and bottom of the horizontal window 5 is equal to the distance between the top and bottom of the vertical window 4 .

[0047] The advantage of this arrangement is that the vertical window 4 and the infrared window formed can basically cover the entire window area 3, with little obstruction. At the same time, we know that the response of infrared rays to black and white is mainly reflected in absorption and reflection. Black objects can absorb most infrared rays, while white objects will reflect most infrared rays.

[0048] Black objects absorb all colors of light, including infrared. This is because black surfaces reflect almost no light but absorb it completely. This property causes black objects to heat up rapidly when exposed to infrared radiation. White objects, on the other hand, reflect most light, including infrared. This reflective nature of white surfaces keeps them relatively cool, preventing them from heating up as quickly as black objects.

[0049] Therefore, in the case of obstruction, a dark-colored housing with an integrated infrared window will absorb some infrared rays. Therefore, it is generally suitable for light-colored housings but not dark-colored housings. However, the structure of the present application can avoid this problem. Since the infrared receiving head 2 has no obstruction in its working area for receiving infrared rays, infrared rays emitted in the vertical and horizontal directions can be received without concern for absorption. Therefore, the housing body 1 can be a light-colored or dark-colored housing, that is, it is suitable for light-colored housings such as white, and also for dark-colored housings such as black.

[0050] Furthermore, the outer contour of the window area 3 is rectangular or circular, as long as the working area of ​​the infrared receiving head 2 is not blocked.

[0051] Furthermore, the vertical window 4 and the horizontal window 5 can be a whole annular groove structure, but considering the role of the shell in isolating the inside and outside, as well as the receiving effect, there are further settings:

[0052] The vertical window 4 comprises a plurality of vertical slots spaced laterally within the window opening area 3; the transverse window 5 comprises a plurality of transverse slots spaced vertically; the distance between two adjacent transverse slots is equal to the distance between two adjacent vertical slots. This configuration not only functions as a housing but also maximizes the window's visible space.

[0053] In some preferred embodiments, when the thickness of some shells is relatively thick, it will also affect the reception of infrared rays. Figure 5 The diagram below shows a comparison of infrared light transmission between large and small thicknesses. Therefore, the following settings are used:

[0054] In the thickness direction of the shell body 1, a recessed groove 8 having the same size as the window area 3 is provided at the location of the window area 3. The size of the recessed groove 8 is substantially the same as that of the window area 3. The outer periphery of the recessed groove 8 is provided with a chamfered portion. A vertical window 4 and a horizontal window 5 are provided on the bottom wall of the recessed groove 8. The depth of the recessed groove 8 is less than the thickness of the corresponding side plate at the location on the shell body 1 where it is located. The effect of the chamfered portion D provided on the outer periphery of the recessed groove 8 can be referred to. Figure 6 The comparison diagram of the state marked C without the groove 8 and the state marked D with the groove 8 shows that the angle range of infrared light received can be increased, thereby improving the infrared receiving performance. The depth of the above groove 8 is less than the thickness of the corresponding side plate at the position where it is located on the shell body 1. Figure 6 The content displayed in the D mark state.

[0055] Second, please refer to Figure 1 and Figure 4 , provides an infrared-transmitting communication device, which includes the above infrared-transmitting housing. The infrared-transmitting communication device simplifies the structure and reduces the cost while ensuring the infrared receiving effect.

[0056] The infrared communication device further includes a PCB board 6 located in the shell body 1 , and the infrared receiving head 2 is mounted on the PCB board 6 and corresponds to the center of the window area 3 .

[0057] Furthermore, the shell body 1 includes a main shell 100 , the lower portion of which is open and connected to a lower bottom shell 101 ; the main shell 100 includes a top plate and surrounding side plates.

[0058] The PCB board 6 is installed in the main housing 100, and the infrared receiving head 2 is installed at the bottom of the PCB board 6 and is located on a side close to the window area 3;

[0059] A light shielding rib 7 is provided in the main housing 100 near the window area 3 ; a side of the light shielding rib 7 away from the window area 3 contacts a side edge of the PCB board 6 near the window area 3 .

[0060] The above structure can be formed as one piece with the infrared window and the main shell 100, which is a plastic structural part. The color of the shell material or the spray color is not restricted. The infrared window is composed of a vertical window 4, a horizontal window 5, and a sink 8. The inner surface of the infrared window is a bright surface, and the outer surface is textured to meet the requirements of infrared remote control and reception in the horizontal and vertical directions. The size of the window area 3 is determined by the infrared receiving head receiving angle of the infrared receiving head 2 and the distance between the infrared receiving head and the window area 3. The size of the window area 3 must not be less than the size determined by the receiving angle and position of the infrared receiving head. The shading rib 7 is combined with the PCB board 6 to block the light and prevent light from leaking from the infrared window into other areas of the main shell 100, such as the area with the indicator light, to avoid affecting the brightness or cross-light.

[0061] At the same time, when assembling the whole machine, there is no need to assemble the infrared window and other structural parts separately, and the PCB board 6 can be directly installed. Finally, the lower bottom shell 101 is closed on the main shell 100 to form the whole machine.

[0062] Furthermore, the lower opening end surface of the main housing 100 is provided with a positioning ring 102 adapted to the shape of its lower opening; the upper end surface of the lower bottom shell 101 is provided with a positioning slot 103 adapted to the positioning ring 102. Figure 7 The schematic diagram of the cooperation between the positioning slot 103 and the positioning ring 102 is shown, in which the two dotted arrows indicate that forces are applied in the left and right directions, and opposite limits are applied in the two directions. That is, due to the snap-fitting of the positioning slot 103 and the positioning ring 102, the main shell 100 is limited in the front, back, left and right directions of the main shell 100 (or limited along the circumference of the main shell 100), avoiding relative displacement between the main shell 100 and the lower bottom shell 101. The two form a whole to enhance the structural strength. When external force acts on the main shell 100, no deformation will occur to affect the light transmission effect of the infrared window. In addition, the connection between the main shell 100 and the lower bottom shell 101 can be connected by fastening bolts, fastening screws or bayonet pins and other structures.

[0063] The infrared communication device of the present application can be applied to products such as set-top boxes and integrated terminals, and can also be applied to other devices or products that need to receive infrared rays.
