[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0029] The embodiment of the present application provides a display device that can be quickly assembled and disassembled.

[0030] See also Figure 1 , Figure 1 A schematic diagram of the structure of a display device provided in an embodiment of the present application.

[0031] The present application provides a display device 100, which can be used in an electronic device, and the electronic device can be at least one of a television (TV), a tablet personal computer, an e-book reader, a desktop PC, a laptop PC, a netbook computer, a workstation, a server, a personal digital assistant, a portable multimedia player, a mobile medical machine, a camera, a game console, a digital camera, a car navigation system, an electronic billboard, an automatic teller machine, or a wearable device. In the following embodiments, the electronic device is described as a television.

[0032] See also Figure 2 as well as Figure 3 , Figure 2 An exploded schematic diagram of a display device provided in an embodiment of the present application, Figure 3 A schematic diagram of the structure of a support bracket provided in an embodiment of the present application. The display device 100 includes a support bracket 10, a circuit board 20, a power supply bracket 30, and a rear shell 40. The support bracket 10 is provided with a slide groove 11. The circuit board 20 is detachably connected to the support bracket 10 through the slide groove 11. The circuit board 20 can slide along a first direction X to be installed on the support bracket 10 or slide along the opposite direction of the first direction X to be removed from the support bracket 10. The rear shell 40 is provided on a side of the circuit board 20 away from the support bracket 10, and the rear shell 40 is detachably connected to the power supply bracket 30.

[0033] The support bracket 10 is a hollow bracket, and the contact area between the hollow bracket and the circuit board 20 is reduced, which is conducive to heat dissipation. The material of the support bracket 10 can be an insulating material, such as insulating plastic, which can avoid short circuit when contacting the circuit board 20, and the insulating plastic is light, which is conducive to reducing the weight of the display device 100.

[0034] The circuit board 20 can be slidably installed on the support bracket 10, and the circuit board 20 can also be slidably removed from the support bracket 10. By sliding the circuit board 20 on the support bracket 10, the relative position of the support bracket 10 and the circuit board 20 can be quickly determined, and the circuit board 20 can also be quickly removed from the support bracket 10.

[0035] The detachable connection between the power supply bracket 30 and the circuit board 20 may be bolt fastening or buckle 32. The detachable connection between the rear housing 40 and the power supply bracket 30 may be bolt fastening or buckle connection.

[0036] The material of the rear shell 40 can be metal or non-metal (such as plastic). If the material of the rear shell 40 is metal, it has high strength and gloss, which is conducive to the fixation of other structures of the display device 100. The metal rear shell 40 can be formed by forging or stamping. If the material of the rear shell 40 is plastic, it has the advantages of being easy to prepare and saving costs, and can be formed by injection molding or extrusion. The plastic can be a material with special properties. For example, the rear shell 40 can be made of a material with a high fire resistance grade such as PC (Polycarbonate) or ABS (Acrylonitrile Butadiene Styrene).

[0037] The rear shell 40 is spaced apart from the circuit board 20, which, on the one hand, facilitates heat dissipation of the circuit board 20 and prevents the circuit board 20 from being directly attached to the rear shell 40 and causing the rear shell 40 to catch fire. On the other hand, the space between the circuit board 20 and the rear shell 40 can protect the circuit board 20 and prevent the circuit board 20 from being damaged when the rear shell 40 is hit.

[0038] During the installation process, the power supply bracket 30 can be first fixed on the circuit board 20, and the circuit board 20 then slides relative to the support bracket 10 to install the circuit board 20 on the support bracket 10, and finally the rear shell 40 is connected to the power supply bracket 30, so that the relative positions of the support bracket 10, the circuit board 20 and the power supply bracket 30 can be quickly fixed. During the disassembly process, the front and rear shells 40 are disassembled from the power supply bracket 30, and the circuit board 20 slides relative to the support bracket 10 to disassemble the circuit board 20 from the support bracket 10, and then the power supply bracket 30 is disassembled from the circuit board 20, so that it is convenient to inspect and repair various structures, especially the circuit board 20. The detachable connection between the power supply bracket 30 and the circuit board 20 can be bolted or connected by snaps 32.

[0039] It can be seen that the structure of only using the rear shell 40 in the present application can replace the double structure of the back plate and the rear shell 40 in the prior art, which is beneficial to the thinness of the display device 100. The side sliding guidance of the circuit board 20 is completed through the slide groove 11 on the support bracket 10 to realize the positioning and connection of the power supply bracket 30 and the support bracket 10, thereby realizing the rapid disassembly and assembly of the overall structure of the display device 100.

[0040] In some embodiments, please refer to Figure 3 as well as Figure 4 , Figure 4 for Figure 3The support bracket 10 includes a base 12 and a plurality of support walls 13 arranged opposite to each other, the plurality of support walls 13 are connected to the base 12, and each of the support walls 13 is provided with a plurality of guide ribs 14, and the plurality of guide ribs 14 and the corresponding support walls 13 form the slide groove 11.

[0041] The number of the supporting walls 13 may be two. The supporting walls 13 are arranged opposite to each other and enclose the base 12 to form a receiving space, and the receiving space can be used to receive the circuit board 20. The guiding ribs 14 are arranged on the supporting walls 13, which not only allow the circuit board 20 and the supporting bracket 10 to slide relative to each other, but also support the circuit board 20 so that the circuit board 20 is spaced apart from the base 12, thereby facilitating heat dissipation of the circuit board 20.

[0042] A plurality of reinforcing ribs 15 may be provided on the base 12. The reinforcing ribs 15 are located in the accommodating space. On the one hand, the base 12 may be reinforced. On the other hand, the reinforcing ribs 15 may be provided to protrude from the base 12, and may be used to support the circuit board 20 to improve reliability.

[0043] Among them, the guide rib 14 includes a first sub-guide segment 141 and a second sub-guide segment 142, the first sub-guide segment 141 and the second sub-guide segment 142 are connected in sequence along the opposite direction of the first direction X, the first sub-guide segment 141 is parallel to the first direction X, and the end of the second sub-guide segment 142 close to the first sub-guide segment 141 gradually deviates from the first direction X to the end away from the first sub-guide segment 141.

[0044] When the circuit board 20 is slidably mounted on the support bracket 10 along the first direction X, the second sub-guide segment 142 extending outward in the opposite direction of the first direction X is used to guide the circuit board 20 to slide in. The connection between the first sub-guide segment 141 and the second sub-guide segment 142 can be a smooth connection to avoid jamming when the circuit board 20 is detachably connected to the support bracket 10 and abrasion of the circuit board 20 at the corners.

[0045] The included angle between the second sub-guide section 142 and the first direction X is 10° to 20°, for example, 8° or 15°. The second sub-guide section 142 plays a guiding role, which facilitates the circuit board 20 to go deep into the slide groove 11, and the first sub-guide section 141 has the function of correcting the sliding direction of the circuit board 20. Therefore, the included angle between the second sub-guide section 142 and the first direction X should not be too large, otherwise a large space is provided to the circuit board 20 during the installation process, and the guiding role is not obvious.

[0046] The plurality of guide ribs 14 on a support wall 13 can be divided into a plurality of first guide ribs 143 and a plurality of second guide ribs 144. The first guide ribs 143 and the second guide ribs 144 respectively form two opposite groove walls of the slide groove 11. The plurality of first guide ribs 143 and the plurality of second guide ribs 144 are staggered. It can be understood that the staggered arrangement of the first guide ribs 143 and the second guide ribs 144 can form the slide groove 11 to support the detachable connection between the circuit board 20 and the support bracket 10, and can also save the number of the first guide ribs 143 and the second guide ribs 144.

[0047] In some embodiments, see Figure 5 , Figure 5 The schematic diagram of the structure of the circuit board and the power supply bracket provided in the embodiment of the present application. The power supply bracket 30 includes a fixing plate 31 and a buckle 32, the fixing plate 31 is connected to the buckle 32, the buckle 32 protrudes from the fixing plate 31 along the first direction X, and the edge of the circuit board 20 is provided with a corresponding slot 21, and the buckle 32 is fixed to the slot 21, so that the power supply bracket 30 is buckled and connected to the circuit board 20.

[0048] Specifically, the circuit board 20 has a first side, a second side, a third side and a fourth side connected in sequence, and the first side and the third side are arranged opposite to each other along the first direction X. The power supply bracket 30 is arranged on the first side of the circuit board 20, and the second side or the fourth side of the circuit board 20 is provided with a card slot 21, and the buckle 32 is elastically deformed and fixed in the card slot 21, so as to fix the power supply bracket 30 on the circuit board 20.

[0049] The power supply bracket 30 further includes a limiting rib 33, which is connected to the fixing plate 31, and the limiting rib 33 protrudes from the fixing plate 31 along the first direction X. A groove is provided on the limiting rib 33, and the edge of the circuit board 20 is engaged with the groove to fix the relative position of the circuit board 20 and the power supply bracket 30. Specifically, the groove on the limiting rib 33 is engaged with the first side edge of the circuit board 20 to fix the positional relationship between the power supply bracket 30 and the circuit board 20, so that the power supply bracket 30 and the circuit board 20 form a fixed angle.

[0050] In some embodiments, see Figure 6 as well as Figure 7 , Figure 6 is a cross-sectional schematic diagram of a display device provided in an embodiment of the present application, Figure 7 for Figure 6The display device 100 further includes a step bolt 50, which includes a head 51, a first rod 52 and a second rod 53, wherein the diameter of the first rod 52 is greater than the diameter of the second rod 53, and the step bolt 50 is passed through the rear housing 40 and the circuit board 20, the second rod 53 is connected to the support bracket 10, the first rod 52 abuts against the circuit board 20, and the head 51 abuts against the rear housing 40.

[0051] The relative positions of the rear housing 40, the circuit board 20 and the support bracket 10 are fixed in the thickness direction of the display device 100 by the step bolts 50. The relative positions of the rear housing 40 and the circuit board 20 can be fixed by the rods of different diameters, thereby improving the stability of the display device 100 and facilitating the spacing of the rear housing 40 and the circuit board 20. As mentioned above, the spacing of the rear housing 40 and the circuit board 20 facilitates the heat dissipation of the circuit board 20 and prevents the circuit board 20 from being directly attached to the rear housing 40 and causing the rear housing 40 to catch fire. On the other hand, the spacing between the circuit board 20 and the rear housing 40 can protect the circuit board 20 and prevent the circuit board 20 from being damaged when the rear housing 40 is hit.

[0052] In some embodiments, the display device 100 further includes self-tapping bolts, and the support bracket 10 and the rear housing 40 are connected by self-tapping bolts to fix the relative position of the support bracket 10 and the rear housing to improve reliability. In the embodiment of the present application, the support bracket 10 and the rear housing 40 can also be fixed by ordinary bolts.

[0053] During the installation process, the groove on the limiting rib 33 on the power supply bracket 30 is clamped to the edge of the circuit board 20, and the buckle 32 on the power supply bracket 30 is clamped to the groove on the circuit board 20 to fix the power supply bracket 30 on the circuit board 20. The circuit board 20 and the support bracket 10 are detachably connected to install the circuit board 20 on the support bracket 10, and then the rear shell 40 and the power supply bracket 30 are fastened by bolts, and the rear shell 40 and the support bracket 10 are fixed by self-tapping bolts, and finally the rear shell 40 and the circuit board 20 are penetrated by the step bolt 50 and the step bolt 50 is connected to the support bracket 10 to fix the relative position of the rear shell 40, the circuit board 20 and the support bracket 10. During the disassembly process, the step bolt 50, the self-tapping bolt between the rear shell 40 and the support bracket 10, and the bolt between the rear shell 40 and the power supply bracket 30 are first removed, and the rear shell 40 is removed from the power supply bracket 30, and then the circuit board 20 is slid relative to the support bracket 10 to remove the circuit board 20 from the support bracket 10, and finally the power supply bracket 30 is disassembled from the circuit board 20. This makes it easier to inspect and repair each structure, especially the circuit board 20, and enables quick inspection and repair.
