Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a rear shell structure and display device. Background Technology

[0002] High quality and low cost are the eternal themes pursued by every company. After years of development, LCD TVs have made great technological progress in terms of form and structure, cost optimization, and other aspects. However, there is still a lot of room for improvement, especially in the integration of modules and the whole machine. Compared with similar products such as laptops, tablets, and mobile phones, LCD TVs lag far behind. Although researchers have conducted in-depth research in this area, they still face limitations in product development, production, after-sales service, usage scenarios, and application habits. As a result, a relatively perfect mass-producible product that can be accepted by all parties has not yet been achieved.

[0003] Traditional TV designs involve a back cover, with modules such as the motherboard, power supply, and speakers fixed behind the back panel and covered by the back cover. The protruding back cover makes it difficult to achieve a wallpaper effect on the TV. In addition, the product is thick, has many parts, and has high overall costs in terms of manufacturing, packaging, and transportation. Utility Model Content

[0022] A first extension section, the first extension section being used to fix the reflector of the light strip and optical components; and,

[0023] The second extension is located on one side of the first extension in the first horizontal direction and is connected to the bracket. One end of the second extension in the first horizontal direction is provided with a through hole corresponding to the first extension.

[0056] This utility model proposes a rear shell structure. It aims to improve upon existing televisions where the rear shell covers modules such as the motherboard, power supply, and speakers, which are fixed behind a back panel and covered by the shell. This design, with its protruding rear shell, makes it difficult to achieve a wallpaper-like effect on the television and results in high overall costs.

[0057] Please see Figure 1-2 as well as Figure 6 In one embodiment of this utility model, the rear shell structure 100 includes a back plate structure 1, a bracket 2, and a decorative strip 3. The back plate structure 1 extends vertically, and the bracket 2 is located on one side of the back plate structure 1 in a first horizontal direction. The bracket 2 is inclined upwards toward the back plate structure 1 and connected to the back plate structure 1. The side of the bracket 2 facing away from the back plate structure 1 is used to fix optical components and liquid crystal glass. The decorative strip 3 connects the lower ends of the back plate structure 1 and the bracket 2. The decorative strip 3, the back plate structure 1, and the bracket 2 enclose a mounting cavity for mounting electronic devices.

[0058] In this invention, the back panel structure 1 extends vertically, and the bracket 2 is inclined upwards towards the back panel structure 1 and connected to it. The inclined surface of the bracket 2 provides support for the optical components and the liquid crystal glass, ensuring the stability of their installation. Simultaneously, the bracket 2, the back panel structure 1, and the decorative strip 3 form the mounting cavity for installing electronic devices. The decorative strip 3 also seals the lower part of the mounting cavity, thus housing the electronic devices within the back shell structure 100. This design eliminates the need for an additional back shell for electronic device installation. The back panel structure 1, on the side furthest from the bracket 2, allows for a large flat surface design, reducing product thickness and the number of parts, achieving a wallpaper-like effect, and lowering overall costs.

[0059] It is understood that in this utility model, the mounting cavity formed by the bracket 2, the back plate structure 1 and the decorative strip 3 has a triangular projection in the second horizontal direction. This arrangement, through the stability characteristics of the triangle, can increase the structural strength of the back shell structure 100, thereby ensuring the installation stability of the optical components, liquid crystal glass and electronic devices.

[0060] To further enhance the structural strength of the mounting cavity formed by the bracket 2, the backplate structure 1, and the decorative strip 3, in one embodiment of this invention, the backplate structure 1 has two mounting sides 11 arranged opposite each other in the second horizontal direction. The bracket 2 is connected to the two mounting sides 11 at both ends in the second horizontal direction, and the upper end of the bracket 2 is connected to the backplate structure 1. With this arrangement, the bracket 2 is connected to the two mounting sides 11 at both ends in the horizontal direction, with the upper end connected to the backplate structure 1 and the lower end connected to the backplate structure 1 via the decorative strip 3. This increases the number of connection points between the bracket 2 and the backplate structure 1, thereby improving the connection strength between the bracket 2 and the backplate structure 1, i.e., improving the structural strength of the mounting cavity. Furthermore, it allows the mounting cavity to become a closed cavity, ensuring the stability of the working environment of the electronic device.

[0061] It should also be noted that, in this utility model, since the lower end of the mounting cavity is closed by the decorative strip 3, in order to facilitate the installation of electronic devices during production and the disassembly and assembly during maintenance, in one embodiment of this utility model, the decorative strip 3 is detachably connected to the back plate structure 1, and the decorative strip 3 is movably connected to the bracket 2. This arrangement allows the connection between the decorative strip 3 and the back plate structure 1 to be first released, and then the decorative strip 3 to be moved relative to the bracket 2, thereby opening the lower end of the mounting cavity. This allows the electronic device to be installed into the mounting cavity from the open end during production, or to be exposed from the open end of the mounting cavity during maintenance, thus facilitating disassembly and assembly.

[0062] In another embodiment of this utility model, the decorative strip 3 is detachably connected to the bracket 2, and the decorative strip 3 is movably connected to the back plate structure 1. This arrangement allows the connection between the decorative strip 3 and the bracket 2 to be first released, and then the decorative strip 3 to be moved relative to the back plate structure 1, thereby opening the lower end of the mounting cavity. This allows electronic devices to be installed into the mounting cavity from the open end during production, or allows electronic devices to be exposed from the open end of the mounting cavity during maintenance, thus facilitating disassembly and repair.

[0063] In another embodiment of this utility model, the decorative strip 3 is detachably connected to the back plate structure 1 and the bracket 2. This arrangement allows the decorative strip 3 to be simultaneously disconnected from the back plate structure 1 and the bracket 2, thereby first removing the decorative strip 3 from the bracket 2 and the back plate structure 1, thus opening the lower end of the mounting cavity to facilitate the installation, maintenance, and disassembly of the electronic device.

[0064] It is understood that this utility model does not limit the specific connection form between the decorative strip 3 and the back plate structure 1 and the bracket 2. In actual installation, it can be selected according to the requirements.

[0065] Furthermore, the detachable connection of the decorative strip 3 allows for direct disassembly of the electronic components, preventing damage to the optical components and the liquid crystal glass during the process, thereby improving the safety of disassembly of the electronic components.

[0066] In addition, please see Figure 9-10 Since the bracket 2 is inclined towards the back plate structure 1 from bottom to top and is used to fix the optical components and liquid crystal glass, in order to ensure the stability of the cooperation between the bracket 2 and the optical components and liquid crystal glass, in one embodiment of this utility model, the bracket 2 includes a first support part 21 and a second support part 22. The first support part 21 extends along a first horizontal direction, and one end of the first support part 21 is stepped upward in the first horizontal direction for fixing the optical components and liquid crystal glass. The second support part 22 is connected to the upper end of the first support part 21. The second support part 22 is inclined towards the back plate structure 1 from bottom to top, and the upper end of the second support part 22 is connected to the back plate structure 1. The second support part 22 is used to support the reflector of the optical components. The decorative strip 3 is connected to the first support part 21. With this configuration, since the optical film and liquid crystal glass are typically arranged vertically, the first support portion 21 is stepped to ensure its support for the optical components and liquid crystal glass. This not only ensures the vertical support performance for the optical components and liquid crystal glass but also guarantees its fixation performance in the first horizontal direction, thus ensuring installation stability. Furthermore, since the optical components include a reflector that is inclined, the second support portion 22 is inclined upwards towards the backplate structure 1, parallel to the reflector, thereby ensuring the support performance of the second support portion 22 for the reflector and ultimately guaranteeing its optical performance.

[0067] It should be noted that, to ensure the supporting performance of the first support part 21 for the optical components and liquid crystal glass, this utility model does not limit the specific material of the first support part 21. In one embodiment of this utility model, the first support part 21 can be made of metal, which can ensure its structural strength. In another embodiment of this utility model, the first support part 21 can also be made of plastic, which can reduce the weight of the first support part 21 while ensuring its supporting performance. In other embodiments of this utility model, the first support part 21 can also be made of other materials. Specifically, it can be selected according to the requirements in actual setting.

[0068] Similarly, this utility model does not limit the specific material of the second support part 22. The material of the second support part 22 can be set as metal, plastic or other materials. In actual installation, it can be selected according to the requirements.

[0069] It is understood that, in a specific embodiment of this utility model, the first support portion 21 includes a first support segment 211, a second support segment 212, and a third support segment 213. The first support segment 211 extends along a first horizontal direction, and its upper end face is used to support the optical component and the liquid crystal glass. The second support segment 212 is located on the side of the first support segment 211 facing the back plate structure 1 and extends vertically. The second support portion 22 is connected to the first support segment 211, and its end face facing away from the back plate structure 1 is used to fix and connect the optical component. The third support segment 213 is located on the upper side of the second support segment 212 and extends along the first horizontal direction. The end of the third support segment 213 facing the back plate structure 1 is connected to the second support portion 22.

[0070] In this embodiment, the first support segment 211 supports the optical component and the liquid crystal glass from top to bottom, thereby ensuring the stability of the optical component and the liquid crystal glass in the top and bottom direction. The second support segment 212 is fixedly connected to one side of the optical component in the first horizontal direction, thereby ensuring the stability of the optical component in the first horizontal direction. At the same time, since the optical component is connected to the liquid crystal glass, the safety and stability of the liquid crystal glass in the first horizontal direction can also be ensured. The third support segment 213 extends along the first direction, and the third support segment 213 can increase the installation space of the optical component and the light illumination space, so that the light energy can fully reach the bottom edge and avoid the impact of black edges and shadows on the visual effect.

[0071] Furthermore, to ensure the connection performance between the decorative strip 3 and the first support portion 21, and to improve the aesthetics of the rear shell structure 100, in one embodiment of this utility model, in the first horizontal direction, the end of the decorative strip 3 away from the back panel structure 1 is bent upwards to abut against the corresponding side end of the first support segment 211. With this arrangement, the first support segment 211 can provide support for the decorative strip 3 in the first horizontal direction, while the decorative strip 3 can also conceal the first support segment 211 in the first horizontal direction, thereby improving the aesthetics of the rear shell structure 100.

[0072] It should be noted that, please refer to Figure 7-8 In this invention, the back plate structure 1 protrudes at least partially from the bracket 2 in a vertically upward direction. In this case, the back plate structure 1 can also abut one end of the optical component in the first horizontal direction. Since the back plate structure 1 extends vertically, to ensure its ability to fix the light strip of the optical module, in one embodiment of this invention, a portion of one end face of the back plate structure 1 in the first horizontal direction protrudes towards the support to form a boss 12. The boss 12 extends in a second horizontal direction and is used to fix the light strip of the optical module. With this configuration, the boss 12 protrudes from the back plate structure 1 in the first horizontal direction, allowing it to be positioned close to the optical module and connect to the light strip to fix and support it, thereby ensuring the installation stability of the light strip.

[0073] It is understood that in a further embodiment of this utility model, the end face of the back plate away from the bracket 2 in the first horizontal direction is provided with a groove corresponding to the boss 12. With this arrangement, the groove and the boss 12 cooperate as a reinforcing member, which can enhance the structural strength of the back plate structure 1 while ensuring the lightweight performance of the back plate structure 1.

[0074] To further enhance the support capability of the backplate structure 1 for the optical components, in a further embodiment of this invention, the backplate structure 1 includes a first plate segment 13 and a second plate segment 14. The first plate segment 13 extends vertically and is fixedly connected to the bracket 2 and the decorative strip 3. The second plate segment 14 is connected to the upper end of the first plate segment 13 and is inclined towards the bracket 2 from bottom to top at a first horizontal level. The second plate segment 14 is used to support the reflector. Thus, the arrangement of the first plate segment 13 ensures that the mounting cavity has sufficient installation space, thereby ensuring that electronic devices can be properly installed into the mounting cavity. The inclined arrangement of the second plate segment 14 allows it to fix the reflector together with the bracket 2. The bracket 2 fixes the lower part of the reflector, and the second plate segment fixes the upper part of the reflector, thereby enhancing the support and fixing capability of the backplate structure 100 for the reflector.

[0075] It is understood that the protrusion 12 is provided on the second plate segment 14 to further fix the lamp strip while ensuring the support and fixing ability of the second plate segment 14 to the reflector, thereby improving the support ability of the second plate segment 14 and strengthening its structural strength.

[0076] Similarly, to enhance the structural strength and support capacity of the first plate segment 13, in one embodiment of the present invention, the first plate segment 13 includes a first extension segment 131 and a second extension segment 132. The first extension segment 131 is used to fix the reflector of the light strip and optical components. The second extension segment 132 is located on one side of the first extension segment 131 in the first horizontal direction and is connected to the bracket 2. One end face of the second extension segment 132 in the first horizontal direction is provided with a through hole corresponding to the first extension segment 131. The opening of the through hole is connected to the first extension segment 131 through an annular connecting rib 133.

[0077] In this embodiment, the first extension segment 131 is provided to support and fix the light strip together with the boss 12, so that the first plate segment 13 and the second plate segment 14 jointly fix the light strip, thereby enhancing the fixing ability of the rear shell structure 100 for the light strip. Furthermore, the first extension segment 131 and the second extension segment 132 are spaced apart in the first horizontal direction, and the second extension segment 132 is connected to the bracket 2. Thus, the second extension segment 132, the bracket 2, and the decorative strip 3 enclose the mounting cavity. Therefore, the provision of the second extension segment 132 can increase the space of the mounting cavity, thereby further ensuring the installation of electronic devices. At this time, the first extension segment 131 and the second extension segment 132 are connected by the annular connecting rib 133. The annular connecting rib 133 can improve the deformation resistance of the first plate segment 13, thereby improving the structural strength of the first plate segment 13.

[0078] It should be noted that the conventional backplate structure 1 usually only has the first extension section 131, which provides support for the optical components in the first horizontal direction.

[0079] It should also be noted that, since the second extension segment 132 connects to the bracket 2, in order to ensure the supporting strength of the second extension segment 132 to the bracket 2, in one embodiment of this utility model, a plurality of reinforcing ribs 134 are protruding from one end face of the second extension segment 132 in the first horizontal direction, and the plurality of reinforcing ribs 134 are spaced apart along the vertical direction or the first horizontal direction. This arrangement, by providing a plurality of reinforcing ribs 134, enhances the deformation resistance of the second extension segment 132, thereby further improving the structural strength of the second extension segment 132 and ensuring the supporting strength of the second extension segment 132 to the bracket 2.

[0080] It is understood that this utility model does not limit the specific placement of the plurality of reinforcing ribs 134. In one embodiment of this utility model, the plurality of reinforcing ribs 134 are located at the end of the second extension 132 facing the bracket 2; in another embodiment of this utility model, the plurality of reinforcing ribs 134 are located at the end of the second extension 132 away from the bracket 2. In actual installation, the ribs can be selected according to the requirements.

[0081] Specifically, in this embodiment, a plurality of reinforcing ribs 134 are provided at one end of the second extension section 132 facing the bracket 2. This arrangement not only strengthens the structural strength of the second extension section 132, but also ensures the aesthetics of the second extension section 132, thereby ensuring the aesthetics of the rear shell structure 100.

[0082] Of course, if it is necessary to strengthen the structural strength of the second extension section 132 while ensuring its lightweight performance, in a further embodiment of this utility model, the end face of the second extension section 132 facing away from the bracket 2 in the first horizontal direction is provided with a plurality of recesses corresponding to the plurality of reinforcing ribs 134. With this arrangement, the plurality of recesses cooperate with the plurality of reinforcing ribs 134 to strengthen the structural strength of the second extension section 132 while ensuring its lightweight performance.

[0083] In a further embodiment of this utility model, the bracket 2 and the first extension segment 131 can be further connected (see 9 and 11). In this embodiment, a reinforcing portion 23 protrudes from the upper end of the bracket 2, and the reinforcing portion 23 at least partially overlaps the first extension segment 131. This arrangement allows the bracket 2 to be supported jointly by the first extension segment 131 and the second extension segment 132, thus distributing the supporting pressure on the second extension segment 132.

[0084] It should be noted that this utility model does not limit the specific structural form of the reinforcing part 23. In one embodiment of this utility model, the reinforcing part 23 can be configured as a reinforcing plate, which overlaps one end of the first extension section 131 in the first horizontal direction. In another embodiment of this utility model, the reinforcing part 23 can also be configured as a plurality of reinforcing rods extending in the vertical direction, with the lower ends of the plurality of reinforcing rods connected to the bracket 2 and the upper ends overlapping one end of the first extension section 131 in the first horizontal direction. In other embodiments of this utility model, the reinforcing part 23 can also be configured as other structural forms. Specifically, it can be selected according to the requirements in actual installation.

[0085] In addition, it should be noted that you may refer to [link / reference needed]. Figure 1-3 To achieve lightweighting of the rear shell structure 100, the back panel structure 1 is thinner in the first horizontal direction. Since the decorative strip 3 connects to the lower end of the back panel structure 1, to ensure the connection stability between the decorative strip 3 and the back panel structure 1 and to prevent the decorative strip 3 from falling off during use, in one embodiment of this invention, the lower end of the back panel structure 1 is bent towards the bracket 2 in the first horizontal direction to form a bent section 15, which connects to the decorative strip 3. Thus, the bent section 15 increases the connection area between the back panel structure 1 and the decorative strip 3, thereby improving the connection stability between the back panel structure 1 and the decorative strip 3 and reducing the probability of the decorative strip 3 falling off.

[0086] Of course, it is understood that this utility model does not limit the specific connection form between the back panel structure 1 and the decorative strip 3. In one embodiment of this utility model, the back panel structure 1 and the decorative strip 3 are bonded together. The upper end face of the decorative strip 3 is provided with a first bonding portion, and the lower end face of the bent section 15 is provided with a second bonding portion. The first bonding portion and the second bonding portion are detachably bonded together. With this arrangement, the bent section 15 can increase the bonding area between the back panel structure 1 and the decorative strip 3, thereby improving the bonding stability between the back panel structure 1 and the decorative strip 3.

[0087] In another embodiment of this utility model, the back panel structure 1 is snap-fitted to the decorative strip 3. In the decorative strip 3 and the bent section 15, one of them is provided with multiple snap-fit ​​parts, and the other is provided with multiple mating parts. When the decorative strip 3 is connected to the back panel structure 1, the multiple snap-fit ​​parts are respectively connected to the corresponding mating parts, thereby realizing the detachable connection between the back panel structure 1 and the decorative strip 3 and ensuring the connection stability between the back panel structure 1 and the decorative strip 3.

[0088] In another embodiment of this utility model, the back plate structure 1 is threadedly connected to the decorative strip 3. The bent section 15 is provided with a first threaded hole in the vertical direction. The decorative strip 3 is provided with a first mating hole 31 corresponding to the first threaded hole. The rear shell structure 100 also includes a first screw. The first screw passes through the first mating hole 31 and extends into the first threaded hole to be threadedly engaged with the first threaded hole. In this way, the setting of the bent section 15 can ensure the setting of the first threaded hole, thereby ensuring the threaded connection between the back plate structure 1 and the decorative strip 3. When it is necessary to disassemble the decorative strip 3, the first screw can be rotated in the vertical direction to release the first screw from the threaded engagement with the first threaded hole, thereby realizing the disassembly of the decorative strip 3.

[0089] It should be further explained that, since the back plate structure 1 is relatively thin, the bending section 15 is also relatively thin. To ensure the stability of the threaded connection between the back plate structure 1 and the decorative strip 3, in a further embodiment of this utility model, the bending section 15 is provided with a first tapping hole 16 extending from bottom to top. The first threaded hole includes the first tapping hole 16, and the first screw passes through the first mating hole 31 to extend into the first tapping hole 16 to engage with the first tapping hole 16 threadedly. This arrangement increases the area of ​​the threaded engagement between the bending section 15 and the first screw, thereby ensuring the stability of the threaded connection between the back plate structure 1 and the decorative strip 3.

[0090] In other embodiments of this utility model, the back panel structure 1 and the decorative strip 3 can also be configured with other connection forms, which can be selected according to the actual needs.

[0091] Specifically, in this utility model, the bent section 15 is provided with a first tapping hole 16 extending from bottom to top, the decorative strip 3 is provided with a first mating hole 31 corresponding to the first tapping hole 16, and the rear shell structure 100 also includes a first screw, which passes through the first mating hole 31 to extend into the first tapping hole 16 to engage with the first tapping hole 16 threadedly.

[0092] Similarly, in order to ensure the connection stability between the bracket 2 and the back plate structure 1 and to prevent the bracket 2 from detaching from the back plate structure 1 during use, in one embodiment of this utility model, the bracket 2 and the back plate structure 1 are configured to be bonded together. Furthermore, since the bracket 2 and the back plate structure 1 are usually in a long-term connected state, the detachability of the bracket 2 does not need to be considered, and the bracket 2 and the back plate structure 1 have a large bonding strength.

[0093] Please see Figure 11 In another embodiment of this utility model, the bracket 2 is threadedly connected to the back plate structure 1. The back plate structure 1 has a second threaded hole at one end face in the first horizontal direction. The bracket 2 has a second mating hole 24 corresponding to the second threaded hole. The rear shell structure 100 also includes a second screw, which passes through the second mating hole 24 and extends into the second threaded hole to thread-mate with it. This arrangement ensures sufficient space for the second threaded hole by extending the back plate structure 1 vertically, and the threaded connection between the second screw and the second threaded hole ensures the stability of the connection between the back plate structure 1 and the bracket 2.

[0094] Because the backplate structure 1 is relatively thin in the first horizontal direction, the area of ​​the threaded engagement between the second threaded hole and the second screw is small. Therefore, in a further embodiment of this invention, to further ensure the connection stability between the bracket 2 and the backplate structure 1, a second tapping hole 17 is provided on one end face of the backplate structure 1 in the first horizontal direction. The second screw passes through the second mating hole 24 to extend into the second tapping hole 17 and is threadedly engaged with the second tapping hole 17. This arrangement increases the area of ​​the threaded engagement between the backplate structure 1 and the second screw, thereby ensuring the stability of the threaded connection between the backplate structure 1 and the bracket 2.

[0095] In other embodiments of this utility model, the back plate structure 1 and the bracket 2 can also be configured with other connection forms. In actual settings, the connection can be selected according to the requirements, and this utility model does not impose any restrictions.

[0096] It should also be noted that the present invention does not limit the flange direction of the second tapping hole 17. In one embodiment of the present invention, the second tapping hole 17 is flanged in the first horizontal direction away from the bracket 2, so as to ensure the threaded connection area between the second screw and the second tapping hole 17.

[0097] In another embodiment of this utility model, the second tapping hole 17 is flanged in the first horizontal direction toward the bracket 2. This not only ensures the threaded connection area between the second screw and the second tapping hole 17, but also improves the aesthetics of the back plate structure 1 on the end face away from the bracket 2 in the first horizontal direction, so as to hide the second screw in the back shell structure 100, ensure the flatness of the back plate structure 1, and make the appearance of the back shell structure 100 more neat and beautiful.

[0098] Specifically, in this utility model, the back plate structure 1 has a second tapping hole 17 through one end face facing the bracket 2 in the first horizontal direction, and the bracket 2 has a second mating hole 24 through the second tapping hole 17. The rear shell structure 100 also includes a second screw, which passes through the second mating hole 24 to extend into the second tapping hole 17 and is threadedly engaged with the second tapping hole 17.

[0099] When the second tapping hole 17 is oriented towards the bracket 2, to avoid interference between the second tapping hole 17 and the second mating hole 24, in one embodiment of this invention, the diameter of the second mating hole 24 is A, and the diameter of the second tapping hole 17 is a, where A > a. With this configuration, the flange of the second tapping hole 17 is located within the second mating hole 24, thus preventing interference between the two and ensuring the stability of the threaded connection.

[0100] Furthermore, when the flange of the second tapping hole 17 is located within the second mating hole 24, to prevent the bracket 2 from shaking when connected to the back plate structure 1, the depth of the second mating hole 24 is B, and the flange height of the second tapping hole 17 is b, where B > b. With this configuration, when the bracket 2 is connected to the back plate structure 1 via the second screw, the nut of the second screw can abut against the bracket 2, and the thread of the second screw is connected to the second tapping hole 17, thereby ensuring the connection stability between the bracket 2 and the back plate structure 1 and preventing the bracket 2 from shaking.

[0101] Specifically, in this utility model, the diameter of the second mating hole 24 is A, the diameter of the second tapping hole 17 is a, A > a, the depth of the second mating hole 24 is B, and the flange height of the second tapping hole 17 is b, B > b.

[0102] It should also be noted that, to ensure the connection stability between the bracket 2 and the back plate structure 1, the structural strength of the connection between the bracket 2 and the back plate structure 1 can be strengthened, thereby ensuring the connection stability. In one embodiment of this utility model, a reinforcing structure 25 protrudes from one end face of the bracket 2 facing the back plate structure 1. The reinforcing structure 25 extends along a second horizontal direction and abuts against the back plate structure 1. The second mating hole 24 passes through the reinforcing structure 25. With this configuration, the nut of the second screw abuts against the bracket 2, and the pressure is transmitted to the back plate structure 1 through the reinforcing structure 25. The connection between the bracket 2 and the back plate structure 1 is transferred through the reinforcing structure 25, thereby increasing the structural strength of the connection between the bracket 2 and the back plate structure 1, and further strengthening the connection stability between the two.

[0103] It is understood that this utility model does not limit the specific structural form of the reinforcing structure 25. In one embodiment of this utility model, the reinforcing structure 25 can be configured as a reinforcing platform, which is located on one end face of the support 2 facing the back plate structure 1. In another embodiment of this utility model, the reinforcing structure 25 can also be configured as a reinforcing plate, which is stacked on one end face of the support 2 in the first horizontal direction. In other embodiments of this utility model, the reinforcing structure 25 can also be configured as other structural forms, which can be selected according to the requirements in actual installation.

[0104] It should be further explained that the reinforcement structure 25 will increase the length of the second screw. When the length of the second screw increases, its bending and shear resistance will decrease, thus affecting the connection stability between the bracket 2 and the back plate structure 1. To ensure that the connection stability is not affected, in a further embodiment of this invention, the end of the bracket 2 facing away from the back plate structure 1 is recessed into the reinforcement structure 25. Multiple first heat dissipation holes 26 are provided in the wall of the recess, and each first heat dissipation hole 26 connects the recess to the mounting cavity. The second mating hole 24 is located at the bottom of the recess. This design reduces the distance between the nut of the second screw and the second tapping hole 17, thereby reducing the length of the second screw and enhancing its bending and shear resistance.

[0105] And, please see Figure 4-5Since electronic devices are installed in the mounting cavity, they generate heat when they are working. To ensure the normal operation of the electronic devices, heat dissipation is required. Therefore, the arrangement of multiple first heat dissipation holes 26 can connect the sink and the mounting cavity, allowing the high-temperature air in the mounting cavity to exchange heat with the low-temperature air outside, thereby preventing the operating temperature in the mounting cavity from overheating.

[0106] Furthermore, since the backplate structure 1, the bracket 2, and the decorative strip 3 enclose the mounting cavity, the backplate structure 1 can also dissipate heat for the electronic devices. In one embodiment of this utility model, the backplate structure 1 is provided with a plurality of second heat dissipation holes 18 along a first horizontal direction, and each second heat dissipation hole 18 connects to the mounting cavity. With this arrangement, the plurality of second heat dissipation holes 18 can also dissipate the high-temperature air in the mounting cavity to the outside, thereby reducing the temperature inside the mounting cavity.

[0107] In a further embodiment of this utility model, the decorative strip 3 is provided with a plurality of third heat dissipation holes 32 extending vertically, and each of the third heat dissipation holes 32 is connected to the mounting cavity. With this arrangement, the plurality of third heat dissipation holes 32 can dissipate the high-temperature air inside the mounting cavity to the outside, thereby reducing the temperature inside the mounting cavity through the decorative strip 3.

[0108] Specifically, in this utility model, the bracket 2 has a recessed groove on one end facing away from the back plate structure 1, corresponding to the reinforcing structure 25. The groove wall is provided with a plurality of first heat dissipation holes 26, each of the first heat dissipation holes 26 connecting the groove and the mounting cavity. The back plate structure 1 is provided with a plurality of second heat dissipation holes 18 along the first horizontal direction, each of the second heat dissipation holes 18 connecting the mounting cavity.

[0109] This utility model also proposes a display device, which includes a liquid crystal glass, an optical component, a rear shell structure 100, and electronic devices. The specific structure of the rear shell structure 100 is as described in the above embodiments. Since this display device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The optical component is disposed on one side of the liquid crystal glass in a first horizontal direction and connected to the liquid crystal glass. The rear shell structure 100 is disposed on the side of the optical component facing away from the liquid crystal glass. The bracket 2 abuts against the optical component. The electronic devices are located in the mounting cavity and connected to the bracket 2.

[0110] It should be noted that, since the bracket 2 includes a first support portion 21, which extends along a first horizontal direction and has one end in a stepped configuration in the first horizontal direction, in order to ensure the connection stability between the optical component and the first support portion 21 and to avoid interference between them, in one embodiment of this invention, the optical component includes a reflective sheet. At least a portion of the reflective sheet is stepped relative to the first support portion 21 to abut against it. This configuration ensures that the reflective sheet is conformally positioned relative to the first support portion 21, guaranteeing proper installation of the reflective sheet, preventing interference from the first support portion 21, and simultaneously ensuring the stability of the support provided by the first support portion 21 to the optical component.

[0111] Furthermore, this utility model does not limit the specific structural form of the display device. In one embodiment of this utility model, the display device can be configured as a monitor; in another embodiment of this utility model, the display device can also be configured as a television; and in other embodiments of this utility model, the display device can also be configured as a mobile phone or other devices with a display screen. In actual settings, the appropriate device can be selected according to the requirements.

[0112] Specifically, in this invention, the display device includes a television set.

[0113] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
