Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display modules, in particular to a lightweight and high-pressure-resistant liquid crystal display module. Background Art

[0002] Liquid crystal display module is a display product that assembles liquid crystal display glass, frame structure, optical film paper, light strip, board and speaker.

[0003] For example, the public document with application number 202223555199.3 discloses a liquid crystal display module. This utility model can protect the circuit board through the cooperation of the plug interface and the extension part, supplemented by the cooperation of the first mounting hole and the second mounting hole, while also making the assembly of the liquid crystal display module body and the protective cover convenient and firm, ensuring the stability and reliability of the connection between the two during use. However, after assembly, the edges of the liquid crystal display module are only protected by a simple outer shell frame. If the display module pursues lightness, then the single outer shell frame will be made relatively thin and light, which will lead to reduced protection and difficulty in bearing high-intensity pressure, and cannot ensure the safety and stability of internal structural parts. On the contrary, if the pressure resistance needs to be improved, the outer shell will be made relatively thick and heavy, which will cause the overall structure to no longer be light and thin, which is not conducive to use. The two restrict each other, greatly affecting the use of the liquid crystal display module.

[0004] Therefore, in view of this, research and improvement are conducted to address the shortcomings of the existing structure, and a lightweight and high-pressure-resistant liquid crystal display module is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a lightweight and thin liquid crystal display module with high pressure resistance to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lightweight and high-pressure-resistant liquid crystal display module, comprising a module assembly frame, a middle frame is provided on the rear side of the module assembly frame, a reinforcing plate is fixedly provided at the edge of the rear side of the surface of the module assembly frame, a sealing rubber sleeve is fixedly provided on the surface of the reinforcing plate, sockets are evenly distributed on the rear end of the surface of the reinforcing plate, slots are provided on the four edges of the surface of the middle frame, support blocks are fixedly installed on the inner surface of the slots, the support blocks match the sockets, and the slots match the reinforcing plates, a back plate is provided on the rear side of the middle frame, and a heat dissipation mechanism is provided on the middle part of the rear side of the surface of the back plate.

[0007] Preferably, the heat dissipation mechanism includes a ventilation hole groove opened in the middle of the rear side of the back plate surface, and a fixing box is fixedly provided on the rear side of the ventilation hole groove on the surface of the back plate.

[0008] Preferably, the heat dissipation mechanism further comprises heat conducting plates evenly distributed and fixed on the inner surface of the fixed box, and the heat conducting plates are in contact with the surface of the air vent grooves.

[0009] Preferably, the heat dissipation mechanism further comprises a dustproof screen fixedly mounted on the rear end of the inner surface of the fixed box, and an exhaust fan is fixedly provided on the middle portion of the inner wall of the dustproof screen.

[0010] Preferably, light strips are evenly distributed and fixedly installed on the front side of the surface of the back plate, and optical components and liquid crystal glass are fixedly installed in sequence from back to front in the middle of the frame body composed of the module assembly frame and the middle frame.

[0011] Preferably, reinforcing ribs are fixedly provided on both left and right sides of the rear surface of the back panel, and a functional interface is installed below the rear surface of the back panel.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The present invention provides a reinforcing plate, a sealing rubber sleeve, a socket, a slot and a support block. After the module assembly frame and the middle frame are assembled, the reinforcing plate will be inserted into the slot, and the support block will be embedded in the socket. The support block and the reinforcing plate will support the slot of the middle frame, so that the upper and lower sides of the slot cooperate with the reinforcing plate to form a closed whole. However, they are independent components. When the frame is under pressure, the three layers of plates share the pressure, and the support block ensures the shape stability, thereby greatly improving the pressure resistance of the entire display module and effectively preventing compression deformation. In addition, the reinforcing plate and the slot are plugged and superimposed for assembly, making full use of the reasonably available space of the front and rear frames. Under the condition of the same module thickness, the frame can be made more solid without increasing the thickness of each frame to improve the strength, thereby making the entire display module lighter and thinner.

[0014] 2. The utility model is provided with a heat dissipation mechanism, air vents, a fixing box, a heat conduction plate, a dustproof screen and an exhaust fan. When the display module is working, the internal light bar emits light and generates heat. The hot air can be discharged outward through the air vents. The heat conduction plate fits inside the air vents and can conduct heat to the back panel and dissipate it, preventing the heat accumulation inside the frame from causing overheating and short circuit of the module. The exhaust fan is used to blow air outward to increase the internal gas flow rate, so that the hot air can be discharged and dissipated more efficiently. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 3 As shown, a lightweight and high-pressure-resistant liquid crystal display module includes a module assembly frame 1, a middle frame 2 is provided on the rear side of the module assembly frame 1, a reinforcing plate 3 is fixedly provided at the edge of the rear side of the surface of the module assembly frame 1, a sealing rubber sleeve 4 is fixedly provided on the surface of the reinforcing plate 3, and sockets 5 are evenly distributed on the rear end of the surface of the reinforcing plate 3. Slots 6 are provided at the four edges of the surface of the middle frame 2, and support blocks 7 are fixedly installed on the inner surface of the slots 6. The support blocks 7 match the sockets 5, and the slots 6 match the reinforcing plate 3. A back plate 8 is provided on the rear side of the middle frame 2, and a heat dissipation mechanism 9 is provided in the middle of the rear side of the surface of the back plate 8.

[0023] By adopting the above technical solution, the module assembly frame 1 and the middle frame 2 are fixed with bolts, the reinforcement plate 3 is inserted into the slot 6, and the support block 7 is embedded in the socket 5. The support block 7 and the reinforcement plate 3 support the slot 6 of the middle frame 2, so that the upper and lower edges of the slot 6 cooperate with the reinforcement plate 3 to form a closed whole, but they are independent components. When the frame is under pressure, the three layers of plates share the pressure, and the support block 7 ensures the stability of the shape, thereby greatly improving the pressure resistance of the entire display module; the reinforcement plate 3 and the slot 6 are assembled in a plug-in and overlapping manner, making full use of the reasonably usable space of the front and rear frames, and can make the frame more solid under the condition of the same module thickness, without increasing the thickness of each frame to increase the strength, thereby making the entire display module lighter and thinner; the sealing rubber sleeve 4 makes the connection between the reinforcement plate 3 and the slot 6 tighter, preventing dust and water vapor from entering the frame through the joints.

[0024] Furthermore, light strips 10 are evenly distributed and fixed on the front side of the surface of the back plate 8, and optical components 11 and liquid crystal glass 12 are fixedly installed in the middle of the frame composed of the module assembly frame 1 and the middle frame 2 from back to front.

[0025] By adopting the above technical solution, the light bar 10 emits light, which is imaged on the liquid crystal glass 12 through the optical component 11 .

[0026] like Figure 4-Figure 5 As shown, the heat dissipation mechanism 9 includes a ventilation hole groove 901 opened in the middle of the rear side of the back plate 8 surface, and a fixing box 902 is fixedly provided on the rear side of the ventilation hole groove 901 on the surface of the back plate 8.

[0027] By adopting the above technical solution, the hot air generated during operation will flow out through the vent holes 901 for self-dissipation of heat.

[0028] Furthermore, the heat dissipation mechanism 9 also includes heat conducting plates 903 evenly distributed and fixed on the inner surface of the fixed box 902 , and the heat conducting plates 903 are in contact with the surface of the vent grooves 901 ; being in contact with the vent grooves 901 means being directly in contact with the back plate 8 .

[0029] By adopting the above technical solution, the heat conducting plate 903 can effectively conduct away and dissipate the heat of the light bar 10 absorbed by the back plate 8 .

[0030] Furthermore, the heat dissipation mechanism 9 also includes a dustproof screen plate 904 fixedly installed on the rear end of the inner surface of the fixed box 902, and an exhaust fan 905 is fixedly provided in the middle of the inner wall of the dustproof screen plate 904.

[0031] By adopting the above technical solution, the exhaust fan 905 can increase the speed at which internal hot air is dissipated outward; and the dustproof screen 904 can prevent dust from entering.

[0032] Furthermore, reinforcing ribs 13 are fixedly provided on both left and right sides of the rear surface of the back plate 8 , and a functional interface 14 is installed below the rear surface of the back plate 8 .

[0033] By adopting the above technical solution, the reinforcing ribs 13 improve the inherent strength of the back plate 8, making the bearing capacity and compressive strength of the back plate 8 higher.

[0034] Working principle: When using the lightweight and high-pressure-resistant liquid crystal display module, first, insert the reinforcement plate 3 of the module assembly frame 1 into the slot 6 of the middle frame 2. At this time, the module assembly frame 1 and the middle frame 2 correspond to each other, and the module assembly frame 1 and the middle frame 2 are fixed with bolts. The reinforcement plate 3 will be inserted into the slot 6, and the support block 7 is embedded in the socket 5. The support block 7 and the reinforcement plate 3 will support the slot 6 of the middle frame 2, so that the upper and lower sides of the slot 6 cooperate with the reinforcement plate 3 to form a closed whole, but they are independent components to each other. When the frame is under pressure, the three layers of plates share the pressure with each other, and the support block 7 ensures the stability of the shape, thereby greatly improving the pressure resistance of the entire display module. The sealing rubber sleeve 4 is attached to the inner surface of the slot 6 to seal the seam to prevent dust and water vapor from leaking. The reinforcement plate 3 and the slot 6 are assembled by plugging and overlapping, making full use of the reasonably usable space of the front and rear frames, and can be used at the same time. Under the condition of equal module thickness, the frame is made more solid, and there is no need to increase the thickness of each frame to improve the strength, so that the entire display module is thinner and lighter, and then the optical component 11 and the liquid crystal glass 12 are assembled into the frame formed by the combination of the module assembly frame 1 and the middle frame 2, and the back plate 8 is covered and fixed with bolts to assemble the module, and the transmission line and the power line are matched and connected with the functional interface 14 to power on and use. When the display module is working, the internal light bar 10 emits light and generates heat, and the heat can be discharged outward through the air vent groove 901. The heat conducting plate 903 is attached to the inside of the air vent groove 901, and can conduct heat dissipation to the back plate 8 to prevent heat accumulation inside the frame from overheating and short circuiting of the module. The exhaust fan 905 is used to blow air outward to increase the internal gas flow rate, so that the heat can be discharged more efficiently. This is the working principle of the lightweight and high-pressure-resistant liquid crystal display module.
