[0086] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0087] Figure 1 This is a schematic diagram of the structure of the display device of the present invention. Figure 2 This is a partial structural schematic diagram of the display device of the present invention, wherein the rear shell 300 is not shown. Figure 3 This is a partial structural schematic diagram of the display device of the present invention.

[0088] See Figures 1 to 3 This embodiment provides a display device, which may include a back panel 100 and a display panel 200 disposed on the front side of the back panel 100. The display device may be a television or a computer monitor, etc., and the following description uses a television as an example.

[0089] A light source and an optical film assembly are located between the back panel 100 and the display panel 200. The light source, optical film assembly, and display panel 200 are arranged sequentially from back to front. The light emitted by the light source is projected onto the display panel 200 after passing through the optical film assembly. The display panel 200 then displays image information. The front side of the display panel 200 is the display surface.

[0090] The back panel 100 is the main support component of the display device, and it is vertically oriented. A forward-protruding frame is formed on the peripheral edge of the back panel 100. The frame is circumferentially arranged and extends around the edge of the back panel 100. The frame extends forward beyond the front side of the back panel 100, and the frame and back panel 100 together form a front-opening mounting cavity for mounting the backlight and optical film assembly. The display panel 200 is fixed to the front end of the frame.

[0091] In this embodiment, the back panel 100 is a structure made of metal, such as iron or aluminum alloy. By using a metal back panel 100, the structural strength of the back panel 100 is maintained while allowing for a thinner design, thus enabling the display device to be designed more slenderly. The back panel 100 is formed by sheet metal stamping.

[0092] The frame can be a middle frame that fixes the periphery of the back panel 100. The middle frame covers the edge of the back panel 100 and surrounds the four periphery of the back panel 100. In some embodiments, the frame and the back panel 100 are integrally formed, and the edge of the back panel 100 extends forward to form the frame, which is circumferentially arranged.

[0093] The light source is used to emit light. The light source and the optical film group are arranged in parallel. The light source is located on the light-incident side behind the optical film group so as to emit light toward the optical film group. The optical film group is located in front of the backlight so that after the light passes through the optical film group, uniform white light is obtained on the light-emitting side in front of the optical film group.

[0094] The backlight is an LED panel, which is attached to the bottom surface of the mounting cavity and emits white light towards the optical film assembly. In some embodiments, the backlight and the optical film assembly are spaced apart in the vertical direction to form a light mixing distance. In other embodiments, the backlight and the optical film assembly are attached together in the vertical direction.

[0095] An optical film assembly is positioned in front of and spaced from the backlight source to improve the uniformity and brightness of the light source. The optical film assembly includes a diffuser plate and multiple films arranged sequentially. The multiple films may include brightness enhancement plates and multiple prism sheets, or multiple films may include multiple prism sheets.

[0096] The display panel 200 is located in front of the optical film group. The light in the optical film group is transmitted forward to the display panel 200. The liquid crystal molecules in the display panel 200 are deflected by the electric field, which reduces the transmittance of the light emitted from the optical film group to the liquid crystal panel, thereby projecting the light into filters of different colors to form an image.

[0097] The display device may further include a rear housing 300 disposed on the back side of the back panel 100, with a cavity formed between the front side of the rear housing 300 and the rear side of the back panel 100. A circuit board 400 is disposed within the cavity, and the circuit board 400 is disposed on the back side of the back panel 100.

[0098] In one embodiment, any one or more of the following components are integrated on the motherboard: power board, driver board, T-con (timing control board, logic board), WiFi board (wireless board), far-field board, remote control board, and button board.

[0099] In one specific embodiment, the motherboard, power board, driver board, T-con (timing control board, logic board), WiFi board (wireless board), far-field board, remote control board, and button board are integrated on a single circuit board 400. Corresponding areas are formed on the circuit board 400, and corresponding electronic components are disposed in those areas.

[0100] By integrating multiple functional boards onto a single circuit board 400 and fixing the single circuit board 400, wiring and plugging steps are reduced, production steps are streamlined, production efficiency is improved, and production costs are reduced.

[0101] Figure 4 This is a partial structural schematic diagram of the back plate 100 of the present invention. Figure 5 This is a schematic diagram of the connection between the new mounting bracket 500 and the back plate 100.

[0102] See Figures 2 to 5 The display device may also include a mounting bracket 500, which is fixed to the back of the back plate 100. The upper part of the circuit board 400 is fixed to the back of the back plate 100, and the lower part is fixed to the mounting bracket 500.

[0103] In some embodiments, a connection hole 110 is provided on the back side of the back plate 100, and a fastener passes through the circuit board 400 and is connected in the connection hole 110 to fix the circuit board 400 to the back plate 100. The fastener used to connect the back plate 100 and the circuit board 400 can be a bolt, screw or rivet, etc.

[0104] In one embodiment, a fixing hole 120 may be provided on the back side of the back plate 100. The fixing hole 120 is used to cooperate with the corresponding structure on the mounting bracket 500 so that the mounting bracket 500 is limited to the back side of the back plate 100.

[0105] In another embodiment, a positioning perforation 130 may be provided on the back side of the back plate 100, and a corresponding structure on the mounting bracket 500 extends into and engages in the positioning perforation 130 for positioning the mounting bracket 500 on the back plate 100.

[0106] In some embodiments, the back surface of the back panel 100 includes a first region 101 and a second region 102; the second region 102 is located at the lower end of the first region 101; the second region 102 is inclined forward and extends in a downward direction; the upper end of the mounting bracket 500 is fixed to the second region 102, and the circuit board 400 is arranged vertically, with the upper part of the circuit board 400 fixed to the first region 101, so that the position of the mounting bracket 500 is further forward. When the circuit board 400 is arranged vertically, it is ensured that the upper part of the circuit board 400 can be fixed to the back panel 100 and the lower part can be fixed to the mounting bracket 500, so as to avoid increasing the thickness of the display device in the front-to-back direction.

[0107] In other embodiments, the back of the back plate 100 protrudes forward in a portion, and a recessed area is formed on the back of the back plate 100, which is a second region 102, and the mounting bracket 500 is fixed to the second region 102.

[0118] See Figure 8The rear cover 300 is disposed on the back of the back panel 100 and covers the rear side of the circuit board 400. A lower plate 310 is disposed on the ground side of the rear cover 300, and the lower plate 310 extends forward from the ground side of the rear cover 300 so that the lower plate 310 is located on the ground side of the rear cover 300. Herein, the ground side is the lower side.

[0119] In some embodiments, the lower plate 310 has an opening 320 that extends vertically through the upper and lower sides of the lower plate 310.

[0123] See Figure 9 and Figure 10 The display device also includes a lower front shell 600, which is fixed to the bottom of the back plate 100 and located below the display panel 200. The lower front shell 600 extends in the left-right direction. The rear shell 300 is fixed to the back of the back plate 100, and the front end of the lower plate 310 is attached to the bottom surface of the lower front shell 600. A concave-convex structure is provided between the upper surface of the lower plate 310 and the lower surface of the lower front shell 600 for limiting the movement between the lower plate 310 and the lower front shell 600.

[0124] In some embodiments, the lower front housing 600 is provided with a recess 610 with a rear opening for limiting the corresponding structure of the mounting bracket 500. Two insertion portions 620 are formed on the bottom surface of the lower front housing 600. Each insertion portion 620 includes a protruding section 621 and a supporting section 622. The protruding section 621 protrudes downward from the bottom surface of the lower front housing 600.

[0125] In other embodiments, a limiting hole 630 is provided on the bottom surface of the lower front shell 600. The limiting hole 630 is used to cooperate with the corresponding structure of the mounting bracket 500 to restrict the rearward movement of the mounting bracket 500.

[0126] Figure 11 This is a schematic diagram showing the connection between the mounting bracket 500 and the circuit board 400 in the first embodiment of the present invention. Figure 12 yes Figure 11 A schematic diagram of the structure from another perspective. Figure 13 yes Figure 11 Enlarged view of point B in the middle. Figure 14 This is a schematic diagram from one perspective of the first embodiment of the mounting bracket 500 of the present invention. Figure 15 This is a structural schematic diagram from another perspective of the first embodiment of the mounting bracket 500 of the present invention.

[0127] See Figures 6 to 15 The mounting bracket 500 may include a fixing part 510 for fixing to the back of the back plate 100. The fixing part 510 is located between the back of the back plate 100 and the rear cover 300.

[0128] In some embodiments, a fixing hole 120 is provided on the back side of the back plate 100, and a protruding positioning hook 511 is formed on the front side of the fixing part 510. The positioning hook 511 engages in the fixing hole 120 to fix the mounting bracket 500 to the back plate 100. The positioning hook 511 protrudes forward from the fixing part 510 and can undergo elastic deformation. The positioning hook 511 extends into the fixing hole 120, and the front end of the positioning hook 511 overlaps the back plate 100 rearward, thereby engaging the positioning hook 511 in the fixing hole 120 to limit the rearward movement of the fixing part 510 relative to the back plate 100.

[0129] In other embodiments, a fastener may be provided between the fixing part 510 and the back plate 100, the fastener fixing the fixing part 510 to the back of the back plate 100.

[0130] In another embodiment, a positioning through hole 130 is provided on the back side of the back plate 100, and a protruding fixing post 512 is formed on the mounting bracket 500. One end of the fixing post 512 protrudes from the front side of the fixing part 510, and the front end of the fixing post 512 passes through the positioning through hole 130 for positioning the fixing part 510 and the back plate 100.

[0131] In some embodiments, the front end of the fixing post 512 passes through the positioning hole 130, and a stepped structure is formed on the periphery of the front end of the fixing post 512. The stepped structure abuts against the back of the back plate 100, restricting the forward movement of the fixing part 510 relative to the back plate 100.

[0132] The vertical height of the fixing part 510 is less than the vertical height of the circuit board 400; the upper end of the fixing part 510 is limited to the back of the back plate 100; the upper and lower parts of the circuit board 400 are respectively provided with fixing holes 410; the upper part of the circuit board 400 is fixed to the back plate 100 through the fixing holes 410, and the lower part of the circuit board 400 is fixed to the fixing part 510 of the mounting bracket 500 through the fixing holes 410. The upper part of the circuit board 400 is fixed to the back plate 100, and the lower part is fixed to the fixing part 510. This ensures the stable fixing of the circuit board 400 and the positional stability between the circuit board 400 and the mounting bracket 500.

[0133] Figure 16 This is a schematic diagram of the connection between the sheet metal part 700 of the present invention and the mounting bracket 500. Figure 17 yes Figure 16 A schematic diagram of the structure from another perspective. Figure 18 This is a structural schematic diagram of the sheet metal part 700 of the present invention.

[0134] See Figures 16 to 18 The vertical height of the fixing part 510 is less than the vertical height of the circuit board 400; the upper end of the fixing part 510 is limited to the back of the back plate 100; the upper and lower parts of the circuit board 400 are respectively provided with fixing holes 410; the upper part of the circuit board 400 is fixed to the back plate 100 through the fixing holes 410, and the lower part of the circuit board 400 is fixed to the fixing part 510 of the mounting bracket 500 through the fixing holes 410. The upper part of the circuit board 400 is fixed to the back plate 100, and the lower part is fixed to the fixing part 510. This ensures the stable fixing of the circuit board 400 and the positional stability between the circuit board 400 and the mounting bracket 500. The upper part of the circuit board 400 is fixed to the first region 101 of the back plate 100, and the fixing part 510 is fixed to the second region 102 of the back plate 100.

[0135] In some embodiments, a protruding fixing post 512 is formed on the fixing part 510, one end of the fixing post 512 protruding from the back side of the fixing part 510, and the fixing post 512 protrudes rearward from the back side of the fixing part 510. A sheet metal part 700 is provided on the fixing part 510; the front end of the sheet metal part 700 abuts against the back plate 100, and the rear end of the sheet metal part 700 is clamped between the rear end of the fixing post 512 and the front side of the circuit board 400. The front end of the sheet metal part 700 abuts against the metal back plate 100, and the rear end of the sheet metal part 700 is clamped between the rear end of the fixing post 512 and the front side of the circuit board 400. The sheet metal part 700 can conduct static electricity on the circuit board 400 to the back plate 100 for electrostatic protection and grounding of the circuit board 400. Furthermore, the rear end of the fixing post 512 abuts against the rear end of the sheet metal part 700, thereby supporting the rear end of the sheet metal part 700 so that the rear end of the sheet metal part 700 abuts against the circuit board 400, thus supporting the circuit board 400.

[0136] Sheet metal part 700 is a structure formed by bending metal materials, such as stainless steel, copper, and iron. Mounting bracket 500 is a structure made of plastic material and is formed by injection molding.

[0137] In some embodiments, the sheet metal part 700 may include an extension section 710, a fitting section 720, and a clamping section 730; the fitting section 720 and the clamping section 730 are respectively formed at both ends of the extension section 710; the clamping section 730 is fixedly connected to the front side of the circuit board 400, and the front and rear sides of the clamping section 730 are respectively fitted to the rear end of the fixing post 512 and the front side of the circuit board 400; the extension section 710 passes through the fixing part 510, and the fitting section 720 is fitted to the back side of the back plate 100; the side of the clamping section 730 facing the fitting section 720 abuts against the rear end of the fixing post 512, and the side of the fitting section 720 facing the clamping section 730 abuts against the fixing part 510. The clamping section 730 abuts against the rear end of the fixing post 512 on the side facing the fitting section 720, and the fitting section 720 abuts against the fixing part 510 on the side facing the clamping section 730. By abutting the clamping section 730 and the fitting section at corresponding positions on the fixing part 510 in opposite directions, the sheet metal part 700 is limited to the fixing part 510.

[0138] In some embodiments, the fixing portion 510 has a through-hole 513 extending from front to back, an extension 710 passing through the through-hole 513, and a fitting portion 720 passing through the through-hole 513. The extension 710 passing through the through-hole 513 allows the sheet metal part 700 to be inserted from the rear side of the fixing portion 510 to the front side. The fitting portion 720 passing through the through-hole 513 facilitates its insertion from rear to front to the front side of the fixing portion 510. The through-hole 513 is provided for mounting the sheet metal part 700 on the fixing portion 510.

[0139] In one embodiment, a protruding reinforcing rib 514 is formed on the front side of the fixing part 510; the fitting section 720 bends and extends from the front end of the extension section 710; the side of the fitting section 720 facing the clamping section 730 abuts against the reinforcing rib 514, and the side of the fitting section 720 facing away from the clamping section 730 abuts against the back plate 100. The side of the fitting section 720 facing the clamping section 730 abuts against the reinforcing rib 514, and the side of the clamping section 730 facing the fitting section 720 abuts against the rear end of the fixing post 512, thus limiting the sheet metal part 700 on the fixing part 510.

[0140] The reinforcing rib 514 protrudes from the front side of the fixing part 510. The side of the fitting section 720 facing the clamping section 730 abuts against the reinforcing rib 514, so that the side of the fitting section 720 facing away from the clamping section 730 abuts against the back plate 100, thereby ensuring contact between the fitting section 720 and the back plate 100 on the sheet metal part 700.

[0141] In one specific embodiment, the clamping section 730 has extension sections 710 at its opposite ends; the two extension sections 710 gradually increase in distance along the direction toward the fitting section 720; the reinforcing ribs 514 are spaced apart; the fitting sections 720 on the two extension sections 710 extend away from each other; the two fitting sections 720 are respectively fitted onto the corresponding reinforcing ribs 514.

[0142] The two extension segments 710 gradually increase in distance from each other in the direction toward the mating segment 720. When the fixing part 510 is fixed to the back plate 100, the extension segments 710 are pressed, and the two extension segments 710 can move in opposite directions, thereby ensuring that the two mating segments 720 are respectively mated to the corresponding reinforcing ribs 514. By gradually increasing the distance from each other in the direction toward the mating segment 720, when the sheet metal part 700 is installed onto the fixing part 510, the elasticity of the two extension segments 710 allows the extension segments 710 to be elastically pressed onto the reinforcing ribs 514, facilitating the quick installation of the sheet metal part 700 onto the fixing part 510.

[0143] In one embodiment, the extending directions of the fitting segment 720 and the clamping segment 730 are opposite. In another embodiment, the extending directions of the fitting segment 720 and the clamping segment 730 are the same.

[0144] In some embodiments, the clamping section 730 has a threaded hole 740, and the rear end of the fixing post 512 has a clearance hole (not shown in the figure); a first fastener (not shown in the figure) is provided between the fixing hole 410 and the threaded hole 740 on the circuit board 400; the first fastener is threadedly connected to the threaded hole 740 and passes through the clearance hole. The circuit board 400 has a fixing hole 410, and the first fastener passes through the fixing hole 410 and is threadedly connected to the threaded hole 740 of the clamping section 730 to fix the sheet metal part 700 to the front side of the circuit board 400. Furthermore, the threaded connection facilitates disassembly and maintenance, eliminating the need for a corresponding threaded hole 740 on the fixing post 512, and the first fastener does not need to be self-tapping on the fixing post 512, thus ensuring the reliability of the circuit board 400's fixation on the fixing part 510.

[0145] See Figures 6 to 15 The mounting bracket 500 may include a fixing part 510 and a far-field part 520 disposed at the lower end of the fixing part 510.

[0146] In some embodiments, the far-field portion 520 extends out of the rear housing 300 through the opening 320, thereby exposing the far-field portion 520 below the rear housing 300. The far-field portion 520 is located below the lower front housing 600, thereby exposing the far-field portion 520 below the lower front housing 600.

[0147] In some embodiments, the far-field portion 520 includes a front wall 521, a bottom wall 522, and a vertical side wall 523; the front wall 521 is fixedly connected to the lower end of the fixing portion 510; one end of the front wall 521 facing away from the fixing portion 510 extends rearward to form the bottom wall 522; the left and right ends of the bottom wall 522 extend upward to form the vertical side wall 523, and the front end of the vertical side wall 523 is connected to the front wall 521; the front wall 521, the bottom wall 522, and the vertical side wall 523 enclose to form a receiving cavity 5201. The receiving cavity 5201 is used to receive the bottom of the circuit board 400, and the bottom of the circuit board 400 can extend into and be confined within the receiving cavity 5201.

[0148] In some embodiments, the circuit board 400 includes a main board area and a far field area; the main board area and the far field area are integrated on a single circuit board 400; the main board area is fixed to the fixing part 510; the far field area is disposed at the bottom of the circuit board 400 and extends into the receiving cavity 5201. A through pickup hole 524 is provided on the front wall 521 of the far field part 520, and a pickup 420 is provided in the far field area corresponding to the pickup hole 524.

[0149] The mounting bracket 500 includes a fixing part 510 and a far-field part 520. The fixing part 510 is fixed to the back of the back plate 100, and the far-field part 520 is disposed at the lower end of the fixing part 510. The far-field part 520 passes downward through the opening 320 at the bottom of the rear cover 300, so that the far-field part 520 is exposed at the bottom of the rear cover 300. The main board area and the far-field area are integrated on a circuit board 400, and the main board area is fixed to the fixing part 510 of the mounting bracket 500. The far-field region includes a front wall 521, a bottom wall 522, and a vertical side wall 523. The front wall 521 is fixedly connected to the lower end of the fixing part 510. The end of the front wall 521 facing away from the fixing part 510 extends rearward to form the bottom wall 522. The left and right ends of the bottom plate extend upward to form vertical side walls 523, and the front ends of the vertical side walls 523 are connected to the front wall 521. The front wall 521, the bottom wall 522, and the vertical side walls 523 enclose a receiving cavity 5201. A through pickup hole 524 is provided on the front wall 521, and the far-field region is located within the receiving cavity 5201. A pickup 420 is provided in the far-field region corresponding to the pickup hole 524, enabling the circuit board 400 to achieve far-field pickup function. The front wall 521, bottom wall 522 and vertical side wall 523 enclose and form a receiving cavity 5201, which can prevent sound from entering from the front and left and right sides of the far field structure, avoid interference with the sound pickup results, reduce noise and improve the sound pickup effect.

[0150] In some embodiments, a protruding stop protrusion 525 is formed on the upper surface of the bottom wall 522; the stop protrusion 525 abuts against the rear side surface of the lower end of the circuit board 400 to limit the bottom end of the circuit board 400.

[0151] In some embodiments, a protruding stop protrusion 525 is formed on the upper surface of the bottom wall 522, and a sealing gasket is provided on the outer periphery of the pickup hole 524 in the accommodating cavity 5201. The bottom front side of the circuit board 400 is attached to the sealing gasket (not shown in the figure). The stop protrusion can press the circuit board 400 forward to ensure a tight fit between the circuit board 400 and the sealing gasket, thereby ensuring the sound pickup effect of the circuit board 400.

[0152] In some embodiments, the lower end of the circuit board 400 extends into the accommodating cavity 5201, and positioning grooves 450 are respectively provided on the left and right sides of the bottom of the circuit board 400; protruding positioning ribs 526 are respectively formed on the opposite surfaces of the two vertical sidewalls 523; the positioning ribs 526 are engaged in the positioning grooves 450 to limit the circuit board 400 in the left-right and up-down directions.

[0153] The opposite sides of the two positioning ribs 526 abut against the sides of the corresponding positioning grooves 450 to position the circuit board 400 in the left-right direction. The upper and lower edges or upper and lower sides of the positioning ribs 526 abut against the sides of the corresponding positioning grooves 450 to position the circuit board 400 in the up-down direction.

[0154] In some embodiments, positioning ribs 526 are respectively provided on the two vertical sidewalls 523 of the far-field portion 520, and a protruding stop protrusion 525 is formed on the upper surface of the bottom wall 522 of the far-field portion 520. When installing the circuit board 400, the lower end of the circuit board 400 is inserted into the receiving cavity 5201, and the rear side of the lower end of the circuit board 400 abuts against the stop protrusion 525. Then, the upper part of the circuit board 400 is rotated forward so that the positioning ribs 526 on the vertical sidewalls 523 are engaged in the positioning grooves 450, thereby positioning and limiting the circuit board 400 on the mounting bracket 500.

[0155] It should be noted that a protruding support rib 527 is formed within the accommodating cavity 5201, and the support rib 527 supports the circuit board 400 upwards. A support portion is provided on the circuit board 400. No electronic components are located at the lower edge of the support area. The support rib 527 supports the circuit board 400 upwards to prevent the bottom end of the circuit board 400 from hitting the bottom wall 522 of the accommodating cavity 5201, thus avoiding damage to the electronic components on the circuit board 400. Specifically, a support cavity 460 is formed in a groove on the circuit board 400, and a support portion is formed at the upper edge of the support cavity 460. The support rib 527 extends into the support area and abuts against the upper edge of the support area. When installing the circuit board 400, the circuit board 400 moves downward relative to the mounting space, so that the upper end of the support rib 527 is supported on the circuit board 400 to position the circuit board 400 in the vertical direction. After the rear side of the bottom end of the circuit board 400 and the stop protrusion 525 abut against each other, the upper end of the circuit board 400 is rotated so that the positioning rib 526 on the vertical side wall 523 is engaged in the positioning groove 450.

[0156] In some embodiments, a downwardly protruding blocking portion 330 is formed on the ground side of the rear housing 300 or the lower surface of the lower plate 310, and the blocking portion 330 blocks the rear side of the far field portion 520.

The upper ends of the two vertical sidewalls 523 extend in opposite directions to form support sections 322, and the lower surfaces of the support sections 322 abut against the support step 321, thereby supporting the far-field portion 520 on the lower plate 310.

[0158] In some embodiments, the circuit board 400 further includes a button area disposed at the bottom of the circuit board 400; the button area is provided with a button 430; a resilient button 528 is provided on the bottom wall 522; the resilient button 528 abuts against the button 430. The button 430 area is integrated on the circuit board 400 to enable the function of the button 430.

[0159] See again Figures 9 to 15 In this application, a lower front shell 600 is provided at the bottom of the back plate 100 and the lower front shell 600 is fixed to the bottom end of the back plate 100; the mounting bracket 500 also includes a limiting part 530; the limiting part 530 extends forward from the far field part 520 or the fixing part 510 and fits against the bottom surface of the lower front shell 600; the front end of the limiting part is limited on the lower front shell.

[0160] In some embodiments, the lower front housing 600 is provided with a socket 610 with a rear opening; a tongue 531 is formed on the upper part of the limiting portion 530, and the tongue 531 passes through the socket 610.

[0161] Two insertion portions 620 are formed on the bottom surface of the lower front cover 600. Each insertion portion 620 includes a protruding section 621 and a supporting section 622. The protruding section 621 protrudes downward from the lower front cover 600. The two supporting sections 622 bend from the bottom end of the protruding section 621 and extend towards each other. The protruding section 621 and the supporting sections 622 enclose the insertion hole 610. The tongue 531 is formed at the left and right ends of the limiting portion 530. The two supporting sections 622 bend from the bottom end of the protruding section 621 and extend towards each other, thereby opening the opposing sides of the two insertion holes 610. The left and right ends of the limiting portion 530 can be inserted into the insertion holes 610 respectively, effectively restricting the movement of the limiting portion 530 in the left and right directions.

[0162] In some embodiments, a protruding limiting buckle 532 is formed at the front end of the limiting part 530, and a limiting hole 630 is provided on the bottom surface of the lower front shell 600; the limiting buckle 532 engages upward in the limiting hole 630 to restrict the rearward movement of the lower front shell 600.

[0163] Figure 19 This is a schematic diagram of the connection of the light guide 550 of the present invention on the mounting bracket 500. Figure 20 This is a partial structural schematic diagram of the mounting bracket 500 of the present invention. Figure 21 This is a schematic diagram of the structure of the light guide 550 of the present invention.

[0164] See Figures 19 to 21 The circuit board 400 also includes a remote control area; the remote control area is located at the bottom of the circuit board 400 and includes an indicator light 440. A through-hole 541 is formed on the mounting bracket 500, penetrating the front wall 521 of the far-field section 520. A light guide 550 passes through the through-hole 541, with the indicator light 440 facing the light guide 550. The light guide 550 is designed to fulfill the functions of remote control, indicator light, and light sensing, ensuring the integration of the remote control board onto the circuit board 400. The light guide 550 is made of a transparent or semi-transparent material to guide light. The light guide 550 is positioned within the through-hole 541 so that its front end is exposed below the lower front housing 600 to receive the light signal from the remote control.

[0165] In some embodiments, the front wall 521 extends forward from the edge of the through hole 541 to form a lower wall 542 and two left and right side walls 543; the two left and right side walls 543 are spaced apart, and the lower ends of the two left and right side walls 543 are respectively connected to the lower wall 542, and the lower wall 542 and the two left and right side walls 543 enclose a limiting cavity 544 with the upper end and the front end open.

[0166] In one embodiment, the light guide 550 is confined within the limiting cavity 544, with its lower side and left and right side surfaces respectively abutting against the corresponding sides of the limiting cavity 544. The lower side surface of the light guide 550 abuts against the lower wall 542; the left and right side surfaces of the light guide 550 abut against the left and right side walls 543 respectively. The light guide 550 is confined within the limiting cavity 544 to prevent the light guide 550 from wobbling on the mounting bracket 500 and to ensure the stability of the position of the light guide 550.

[0167] In some embodiments, protruding protrusions 551 are formed on the left and right sides of the front end of the light guide 550. The protrusions 551 abut against the front end of the left and right sidewalls 543, restricting the light guide 550 from moving backward and preventing the light guide 550 from retracting into the far field portion 520, thus ensuring the normal light guiding of the light guide 550.

[0168] In some embodiments, the mounting bracket 500 further includes a limiting portion 530; the limiting portion 530 extends forward from the far-field portion 520 or the fixing portion 510; the upper ends of the two left and right sidewalls 543 are respectively connected to the limiting portion 530. The limiting portion 530 has a stop portion 545 formed at the front end of the left and right sidewalls 543; when the lower side of the light guide 550 is in contact with the lower wall 542, the stop portion 545 abuts against the upper end of the protrusion 551. This restricts the upward movement of the front end of the light guide 550, preventing the light guide 550 from dislodging upward from the limiting cavity 544.

[0169] Furthermore, each of the two left and right sidewalls 543 has a stop portion 545 at its front end; the opposing surfaces of the two stop portions 545 are inclined toward each other in the downward direction. When installing the light guide 550, the light guide 550 is pressed downward, and the opposing surfaces of the two stop portions 545 are inclined toward each other in the downward direction to guide the protrusion 551 when it is installed downward.

[0170] In some embodiments, the bottom of the fixing part 510 has a through-hole 546 extending from front to back, with the lower end of the through-hole 546 penetrating through the through-hole 541. The through-hole 546 is configured to allow the light guide 550 to extend into the through-hole. The height of the through-hole is greater than the vertical thickness of the light guide 550. When installing the light guide 550, the light guide 550 extends into the through-hole, and then the light guide 550 is moved downwards to install it within the limiting cavity 544, facilitating the installation of the light guide 550.

[0171] In some embodiments, the vertical height of the left and right sidewalls 543 is greater than the vertical thickness of the light guide 550; protruding limiting protrusions 547 are formed on the left and right sidewalls 543; when the lower side of the light guide 550 is attached to the lower wall 542, the limiting protrusions 547 abut against the upper end of the light guide 550. The vertical height of the left and right sidewalls 543 is greater than the vertical thickness of the light guide 550 so that the limiting protrusions 547 can be provided at the upper end of the left and right sidewalls 543. The limiting protrusions 547 abut against the upper end of the light guide 550, restricting the upward movement of the light guide 550.

[0172] Limiting protrusions 547 are respectively provided on the opposite surfaces of the two left and right sidewalls 543; the opposite surfaces of the two limiting protrusions 547 are inclined towards each other in the downward direction. When installing the light guide 550, the light guide 550 is pressed down, and the opposite surfaces of the two limiting protrusions 547 are inclined towards each other in the downward direction to guide the light guide 550 during downward installation.

[0173] In this application, recessed positioning grooves 548 are formed on the left and right sidewalls 543; protruding positioning protrusions 552 are formed on the left and right sides of the light guide 550; when the lower side of the light guide 550 is attached to the lower wall 542, the positioning protrusions 552 are engaged in the positioning grooves 548, restricting the movement of the light guide 550 in the front and back directions.

[0174] The positioning groove 548 extends vertically and penetrates the upper end of the left and right side walls 543. When the light guide 550 is pressed down and installed in the limiting cavity 544, the positioning groove 548 penetrates the upper end of the left and right side walls 543, making it convenient to engage the positioning protrusion 552 in the positioning groove 548.

[0175] In some embodiments, two support ribs 527 are spaced apart in the left-right direction. The upper end of the support rib 527 is used to support the circuit board 400. The left and right sides of the rear end of the light guide 550 abut against the two support ribs 527 respectively to limit the left and right movement of the rear end of the light guide 550. The support ribs 527 protrude from the bottom wall 522, and the front end of the support rib 527 is connected to the front wall 521.

[0176] Based on the corresponding structures on the light guide 550 and the mounting bracket 500, when installing the light guide 550, the light guide 550 passes through the clearance hole 546 in the front-to-back direction, and the light guide 550 is pressed downwards. When the light guide 550 is pressed downwards, the limiting protrusion 547 and the stop portion 545 can be used for guidance. When the light guide 550 is pressed downwards to the installation position, the light guide 550 is limited in the limiting cavity 544, the positioning protrusion 552 is engaged in the positioning groove 548, the protrusion portion 551 abuts against the front end of the left and right side walls 543, and the stop portion 545 abuts against the upper end of the protrusion portion 551. At the same time, the limiting protrusion 547 abuts against the upper end of the light guide 550.

[0178] See Figures 11 to 26 and combined Figures 1 to 25 The structure of the second embodiment of the mounting bracket 500 is the same as that of the first embodiment of the mounting bracket 500, except that:

[0179] In the second embodiment of the mounting bracket 500, no stop protrusion 525 is provided on the bottom wall 522 of the mounting bracket 500. A detachable or separable limiting member 560 is provided inside the mounting bracket 500. At least the lower end of the limiting member 560 is located in the receiving cavity 5201. The limiting member 560 is limited on the far field portion 520, and the front end of the limiting member 560 abuts against the rear side of the lower end of the circuit board 400, thereby restricting the rearward movement of the lower end of the circuit board 400.

[0180] In some embodiments, limiting holes 561 are provided on the left and right sides of the limiting member 560; positioning ribs 526 are provided on the opposite surface of the vertical sidewall 523 on the far field portion 520, and the positioning ribs 526 can be engaged in the limiting holes 561 to restrict the movement of the limiting member 560 in the up and down and left and right directions.

[0181] In other embodiments, a stop hole 529 is provided on the bottom wall 522; an elastic buckle 562 is formed at the bottom of the limiting member 560; the elastic buckle 562 can engage in the stop hole 529. The elastic buckle 562 at the bottom of the limiting member 560 engages in the stop hole 529, restricting the backward movement of the limiting member 560, so as to ensure that the front end of the limiting member 560 abuts and limits the circuit board 400.

[0182] In one embodiment, the left and right ends of the lower part of the limiting rib abut against the opposite surfaces of the two vertical sidewalls 523, respectively, to restrict the movement of the limiting rib in the left and right directions.

[0183] In some embodiments, protruding positioning portions 563 are formed at the left and right ends of the limiting member 560; positioning holes 564 are provided on the bottom surface of the positioning portions 563. A protruding positioning protrusion 565 is formed at the upper end of the vertical sidewall 523; the positioning protrusion 565 engages in the positioning hole 564, restricting the movement of the limiting member 560 in the rearward direction, so as to ensure that the front end of the limiting member 560 abuts against and limits the circuit board 400.

[0184] In the second embodiment of the mounting bracket 500, when the lower end of the circuit board 400 is mounted on the mounting bracket 500, the circuit board 400 moves forward so that the positioning grooves 450 on the left and right sides of the bottom of the circuit board 400 engage with the positioning ribs 526 on the opposite surfaces of the vertical sidewalls 523, restricting the vertical and horizontal movement of the circuit board 400. The limiting member 560 moves from back to front so that the limiting hole 561 on the limiting member 560 engages with the positioning ribs 526, restricting the vertical and horizontal movement of the limiting member 560. The elastic buckle 562 engages with the stop hole 529, restricting the rearward movement of the lower part of the limiting member 560. The positioning protrusion 565 engages with the positioning hole 564, restricting the rearward movement of the upper part of the limiting member 560.
