[0029] like Figure 1 to Figure 2 As shown, the embodiment of the present application provides a set-top box, including a shell 1, a bracket 2 and a circuit assembly. The shell 1 is provided with a first cavity 11, a first opening 12 is provided on one end face of the shell 1, a second opening 13 is provided on the peripheral side of the shell 1, and an infrared window 4 is also provided on the peripheral side of the shell 1; the bracket 2 is located in the first cavity 11 and is detachably connected to the shell 1, and the bottom plate 21 of the bracket 2 is adapted to the first opening 12; the circuit assembly is detachably connected to the bracket 2, and the circuit assembly includes a circuit board 31, a plurality of antennas 32 electrically connected to the circuit board 31, an interface board 33 and an infrared head, the interface board 33 is adapted to the second opening 13, and the output end of the infrared head faces the infrared window 4.

[0030] It should be understood that the present application includes a shell 1, a bracket 2 and a circuit assembly. The shell 1 is barrel-shaped, and is provided with a first cavity 11. A first opening 12 is provided on one end face of the shell 1 along the length direction, and the first opening 12 is connected to the first cavity 11, so that the bracket 2 and the circuit assembly can be installed or removed from the first cavity 11 through the first opening 12. A second opening 13 is also provided on the peripheral side of the shell 1, and the second opening 13 is connected to the first cavity 11. One end of the second opening 13 facing the first opening 12 is also opened to facilitate the installation or removal of the bracket 2 and the circuit assembly. An infrared window 4 is also provided on the peripheral side of the shell 1, and the infrared window 4 and the shell 1 can be formed in an integral manner or connected in a detachable manner.

[0031] The bracket 2 is installed in the first cavity 11 and is detachably connected to the housing 1, and can be fixed by bolts, pins or clamping. The bracket 2 is provided with a bottom plate 21, and the bottom plate 21 of the bracket 2 is adapted to the first opening 12. When the bracket 2 is located in the first cavity 11, the bottom plate 21 of the bracket 2 is located at the first opening 12, thereby preventing the objects in the first cavity 11 from falling and preventing foreign objects from entering from the first opening 12. The bottom plate 21 of the bracket 2 is connected to the housing 1 by bolts.

[0032] The circuit assembly is detachably connected to the bracket 2, and the circuit assembly includes a circuit board 31, multiple antennas 32, an interface board 33, and an infrared head. The circuit board 31 is detachably connected to the bracket 2, for example, by bolts, snap-fitting, etc. Multiple antennas 32 are electrically connected to the circuit board 31, so as to transmit electrical signals to the circuit board 31 or transmit electrical signals from the circuit board 31. The multiple antennas 32 are detachably connected to the bracket 2, for example, by bonding, snap-fitting, etc. The interface board 33 is connected to the circuit board 31 signal. The interface board 33 is a functional board responsible for input and output (I / O). The interface board is composed of I / O dedicated devices, control software, connectors, etc. The interface circuit converts the signal on the host (board) into a signal that can be recognized by the peripheral device. The interface board 33 is detachably connected to the bracket 2, for example, by bolts, snap-fitting, etc., and in order to facilitate the connection between the interface board 33 and other external parts, the interface board 33 protrudes from the outer surface of the bracket 2. When installing, the interface board 33 is installed in the second opening 13 to avoid the shell 1 blocking the interface board 33. The infrared head is electrically connected to the circuit board 31, and can transmit electrical signals to the circuit board 31 or transmit signals from the circuit board 31. The infrared head is detachably connected to the bracket 2, for example, by bolts, snap-ons, etc. The output end of the infrared head faces the infrared window 4 to facilitate the normal operation of the infrared head.

[0033] During installation, first install the circuit board 31, multiple antennas 32, interface board 33 and infrared head of the circuit assembly on the bracket 2, and then insert the bracket 2 with the circuit board 31 installed into the first cavity 11. At this time, it is necessary to pay attention to engage the interface board 33 with the second opening 13, and face the output end of the infrared head toward the infrared window 4. After the insertion is completed, connect the bracket 2 with the shell 1. The present application installs multiple parts in the circuit assembly through a bracket 2, and then connects the bracket 2 with the shell 1. Compared with installing multiple parts on multiple brackets 2 and then installing multiple brackets 2 on the shell 1, the present application reduces the steps of installing the circuit assembly and the shell 1, and improves the convenience of assembling and disassembling the circuit assembly and the shell 1.

[0034] In some optional embodiments, the bracket 2 is provided with a second cavity 25, and the circuit board 31 is adapted to the second cavity 25 and is detachably connected to the bracket 2. When the circuit board 31 is installed in the second cavity 25, the circuit board 31 is hidden in the bracket 2, thereby preventing the circuit board 31 from protruding from the outer surface of the bracket 2. When the bracket 2 is inserted into the housing 1, the housing 1 can be prevented from touching the circuit board 31, thereby preventing the circuit board 31 from being damaged. The circuit board 31 is detachably connected to the bracket 2, and the bracket 2 is provided with a first stud at the second cavity 25, and a first screw hole is provided at a corresponding position of the circuit board 31. The screw passes through the first screw hole of the circuit board 31 and is threadedly connected to the first stud of the bracket 2, thereby connecting the circuit board 31 to the bracket 2. Among them, a button is also provided at the bracket 2, and the button performs a physical pressing operation on the circuit board 31.

[0035] In some optional embodiments, the outer wall of the bracket 2 is provided with a plurality of antenna slots 26, and the plurality of antennas 32 are detachably connected to the plurality of antenna slots 26. The number of antennas 32 is provided in plurality to realize different transmission functions. The number of antenna slots 26 is not less than the number of antennas 32, and the plurality of antenna slots 26 may be located at the corners or the peripheral side walls of the bracket 2. The antenna slot 26 is adapted to the antenna 32 to facilitate the installation of the antenna 32. The antenna 32 may be bonded to the antenna slot 26 by adhesive, and an undercut may be provided at the antenna slot 26 to press and snap the antenna 32 in. When the antenna 32 is located in the antenna slot 26, the antenna 32 is hidden in the bracket 2 to prevent the antenna 32 from protruding from the outer surface of the bracket 2. When the bracket 2 is inserted into the housing 1, the probability of collision between the housing 1 and the antenna 32 is reduced, and the probability of damage to the antenna 32 during installation is reduced.

[0036] Reference Figure 3 and Figure 4 , Figure 3 A cross-sectional view of a set-top box provided in an embodiment of the present application is shown. Figure 4FIG. 2 shows a top view of a bracket provided by an embodiment of the present application. In some optional embodiments, one end of the bracket 2 facing away from the bottom plate 21 is provided with an anti-rotation column or an anti-rotation hole 22, and the inner wall of the corresponding housing 1 is provided with an anti-rotation column 14 or the other of the anti-rotation holes, and the anti-rotation column 14 and the anti-rotation hole 22 cooperate with each other.

[0037] In one example, an anti-rotation column is protruding from one end of the bracket 2 away from the bottom plate 21; an anti-rotation hole is opened on the inner wall of the end of the shell 1 away from the first opening 12. When the bracket 2 is installed in the first cavity 11, the anti-rotation column is inserted into the anti-rotation hole, so that the bracket 2 and the shell 1 are accurately positioned, thereby avoiding relative rotation between the shell 1 and the bracket 2 during later use, avoiding misalignment between the interface board 33 in the circuit assembly and the second opening 13, and avoiding misalignment between the infrared head and the infrared window 4.

[0038] In one example, an anti-rotation hole 22 is recessed at one end of the bracket 2 facing away from the bottom plate 21; an anti-rotation column 14 is integrally formed on the inner wall of one end of the shell 1 facing away from the first opening 12. When the bracket 2 is installed in the first cavity 11, the anti-rotation column 14 is inserted into the anti-rotation hole 22, so that the bracket 2 and the shell 1 are accurately positioned, thereby avoiding relative rotation between the shell 1 and the bracket 2 during later use, avoiding misalignment between the interface board 33 in the circuit assembly and the second opening 13, and avoiding misalignment between the infrared head and the infrared window 4.

[0039] In some optional embodiments, at least one protrusion 141 is provided on the circumference of the anti-rotation column 14, and the protrusion 141 extends along the length direction of the anti-rotation column 14. The circumference of the anti-rotation column 14 is integrally formed with a protrusion 141, and the number of protrusions 141 can be one, two, or more. When the number of protrusions 141 is more than one, the multiple protrusions 141 are arranged at intervals along the circumference of the anti-rotation column 14. The anti-rotation hole 22 is also provided with grooves adapted to the protrusions 141, and the number of the grooves corresponds to the number of the protrusions 141. The provision of the protrusions 141 can prevent the anti-rotation column 14 from rotating in the anti-rotation hole 22, and further improve the accuracy of the installation of the bracket 2 and the housing 1.

[0040] In one example, there are three protrusions 141 , which are spaced apart around the outer circumference of the anti-rotation post 14 , and there are also three grooves of the anti-rotation hole 22 corresponding to the three protrusions 141 .

[0041] In some optional embodiments, the number of the anti-rotation columns 14 is at least two, and the number of the anti-rotation holes 22 is also at least two, so as to further improve the installation accuracy of the bracket 2 and the housing 1.

Figure 5A schematic diagram of the structure of a bracket provided in an embodiment of the present application is shown. Figure 6 A schematic diagram of the structure of a shell provided by an embodiment of the present application is shown. In some optional embodiments, the inner wall of the shell 1 extends with a first limiting rib 15 along the height direction of the shell 1, and the corresponding outer wall of the bracket 2 extends with a second limiting rib 23 along the height direction of the bracket 2, and the first limiting rib 15 and the second limiting rib 23 cooperate with each other. The first limiting rib 15 is located in the first cavity 11 and is integrally formed with the inner wall of the shell 1, and the first limiting rib 15 extends along the height direction of the shell 1; the second limiting rib 23 is arranged on the outer wall of the bracket 2 and is integrally formed with the bracket 2, and the second limiting rib 23 extends along the height direction of the bracket 2. When the bracket 2 extends into the first cavity 11, the first limiting rib 15 fits with the second limiting rib 23, reducing the situation where the bracket 2 is skewed or swings left and right in the first cavity 11. The number of the first limiting rib 15 and the second limiting rib 23 can be set in multiples and arranged at intervals, which can further reduce the situation where the bracket 2 is skewed or swings left and right in the first cavity 11.

[0043] In some optional embodiments, the inner wall of the shell 1 extends along the height direction of the shell 1 to form one of the slides 16 or the slide rails, and the corresponding outer wall of the bracket 2 extends along the height direction of the bracket 2 to form the other of the slides or the slide rails 24, and the slides 16 and the slide rails 24 cooperate with each other.

[0044] In one example, the inner wall of the housing 1 is integrally formed with a slideway 16, which extends in the height direction of the housing 1, and the outer wall of the bracket 2 is integrally formed with a slide rail 24, which extends in the height direction of the bracket 2, and the slide rail 24 cooperates with the slideway 16.
