Description

Technical Field

[0001] This application relates to the technical field of liquid crystal display devices, and in particular to a front frame assembly of a waterproof housing for a liquid crystal display device. Background Art

[0002] A liquid crystal television, also known as an LCD television, utilizes the optical anisotropy characteristics of liquid crystals to modulate light under the action of an electric field to achieve information display. It adopts a backlight principle, uses a lamp tube as a backlight source, and combines an auxiliary optical module and a liquid crystal layer to control light to present an image. A liquid crystal television itself does not emit light and relies on an electric field generated by a voltage change to change the arrangement of liquid crystal molecules, thereby displaying an image.

[0003] Liquid crystal televisions are usually watched at home. However, in some public facilities, such as bath centers, saunas, etc., liquid crystal televisions are also usually installed.

[0004] However, in such a high-temperature and high-humidity environment, water vapor can easily enter the liquid crystal television. Especially for the front frame assembly of the display screen, water often accidentally splashes onto it, resulting in equipment failures. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, the purpose of this application is a front frame assembly of a waterproof housing for a liquid crystal display device, which is used to solve the technical problem of poor waterproof performance of the front frame assembly of the waterproof housing of a liquid crystal display device in a high-humidity environment.

[0006] The above object of this application is achieved through the following technical solutions: A front frame assembly of a waterproof housing for a liquid crystal display device includes four side frames and tempered glass disposed between the four side frames. U-shaped grooves are opened on the side frames, and the tempered glass is inserted into the four side frames through the U-shaped grooves. A placement groove for placing a semi-fluid silicone body is provided on the U-shaped groove and is opened on the side frame. A corner connector for fixing the side frames is installed between the side frames.

[0007] By adopting the above technical solutions, the tempered glass is clamped by the asymmetric U-shaped grooves provided on the four side frames. During assembly, first, a semi-fluid viscous silicone body is poured into the placement groove in the U-shaped groove, and then the tempered glass is pushed into the U-shaped groove. After the semi-fluid silicone body is squeezed by the tempered glass, the excess semi-fluid silicone body will also overflow to both ends in the length direction of the four front frames and merge with the four corner connectors. The semi-fluid viscous silicone body will solidify after a certain period of time to form an effect of adhesion and filling gaps, thereby greatly improving the waterproof performance of the front frame assembly of the display.

[0008] Furthermore, through grooves are also opened on two pairs of sides of the U-shaped groove, and the two through grooves on both sides are in an irregular shape.

[0009] By adopting the above technical solution, when the semi-fluid silica gel is extruded by the tempered glass into the placement grooves on the upper and lower sides, the excess semi-fluid silica gel will also overflow to both ends in the length direction of the four frames. By additionally providing through grooves in the U-shaped grooves, the waterproof effect can be further improved.

[0010] Furthermore, the cross-section of the placement groove presents an inverted trapezoidal shape, and the wide side is at the end close to the tempered glass.

[0011] By adopting the above technical solution, in order to ensure that the amount of the semi-fluid silica gel overflowing from both ends of the placement groove is consistent during pouring, it is set in an inverted trapezoidal shape. When the semi-fluid silica gel overflows from the placement groove, the inclined surfaces at both ends will reduce the overflow speed, making it convenient for the staff to adjust. Through manual intervention, the amount of the semi-fluid silica gel flowing out from both ends of the placement groove is kept consistent, thus ensuring the same sealing performance at both ends.

[0012] Furthermore, a butting groove is also provided on the U-shaped groove, and a sealing silica gel strip is fixedly arranged in the butting groove.

[0013] By adopting the above technical solution, through the elastic compression characteristic of the sealing strip, the tempered glass and the front frame are closely attached to form a secondary seal.

[0014] Furthermore, the corner connecting piece is composed of a pair of vertically connected connecting blocks. Connecting grooves are respectively provided at the ends of the frames, and the connecting blocks are inserted into the connecting grooves.

[0015] By adopting the above technical solution, the connecting blocks are vertically connected, and the frames are connected together by the insertion method, improving the convenience during assembly and installation.

[0016] Furthermore, convex blocks for blocking water vapor are provided at both ends of the connecting block, and the convex blocks are fixedly connected to the connecting block.

[0017] By adopting the above technical solution, the convex blocks are made of rubber. After the connecting block is inserted into the connecting groove on the frame, the setting of the convex blocks increases the sealing performance between the frames.

[0018] Furthermore, multiple groups of convex blocks are provided and are spaced apart on the connecting block.

[0019] By adopting the above technical solution, by providing multiple groups of convex blocks on the connecting block and spacing them apart on the connecting block, after the connecting block is inserted into the insertion groove, the blocking of multiple groups of convex blocks can further improve the sealing performance between the frames.

[0020] Furthermore, sealant for increasing the sealing performance is applied between the convex blocks.

[0021] By adopting the above technical solution, during assembly, sealant is first applied to the surface of the bump, and then the bump is inserted into the through groove of the frame. The sealant cures and forms a connection structure with the through groove of the frame in the groove beside the bump, playing a role in waterproofing and structural strengthening.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the combination of the asymmetric U-shaped groove and the semi-fluid silicone body, the tight fixation and waterproof sealing between the tempered glass and the frame are achieved. The semi-fluid silicone body forms a firm waterproof layer after curing, and the waterproof effect is further enhanced through the through groove design to ensure that water cannot penetrate. At the same time, the setting of the sealing silicone strip and the rubber bump provides double sealing guarantees, greatly improving the overall waterproof performance.

[0024] 2. The front frame assembly adopts the plug-in corner connector and the inverted trapezoidal placement groove design, which simplifies the assembly process and improves the installation efficiency. The inverted trapezoidal placement groove enables the staff to conveniently adjust when pouring the semi-fluid silicone body, ensuring that the amount of silicone overflowing at both ends is the same, thereby ensuring the uniformity of the sealing performance. This design not only improves the production efficiency but also reduces the assembly difficulty.

[0025] 3. The semi-fluid silicone body not only plays a waterproof role after curing but also serves as a filling material to enhance the structural connection between the frame and the tempered glass, improving the stability of the entire front frame assembly. At the same time, the bumps and sealing strips made of durable materials such as rubber and silicone can effectively resist aging and wear, extending the service life of the product. This design ensures that the front frame assembly maintains stable performance during long-term use. Description of the Drawings

[0030] The following further describes the present application in detail with reference to the drawings.

[0031] Embodiment, referring to Figure 1 - Figure 3, a front frame assembly of a waterproof housing for a liquid crystal display device, comprising four side frames 1 and a tempered glass 2 disposed between the four side frames 1. U-shaped grooves are formed on each of the side frames 1, and the tempered glass 2 is inserted into the four side frames 1 through the U-shaped grooves. A placement groove 11 for adding semi-fluid silicone is formed on the U-shaped groove and is opened on the side frame 1. A corner connector 3 for fixing the side frames 1 is installed between the side frames 1. The tempered glass 2 is clamped by the asymmetric U-shaped groove positions provided on the four side frames 1. During assembly, first, a semi-fluid viscous silicone is poured into the placement groove 11 in the U-shaped groove, and then the tempered glass 2 is pushed into the U-shaped groove. After the semi-fluid silicone is extruded by the tempered glass 2, the excess semi-fluid silicone will also overflow to both ends in the length direction of the four front frames and merge with the four corner connectors 3. The semi-fluid viscous silicone will solidify after a period of time to form an effect of adhesion and filling gaps, thereby greatly improving the waterproof performance of the front frame assembly of the display.

[0032] In this embodiment, through grooves 12 are further formed on two opposite sides of the U-shaped groove, and the two through grooves 12 have an irregular shape. After the semi-fluid silicone is extruded by the tempered glass 2 and flows into the placement grooves 11 on the upper and lower sides, the excess semi-fluid silicone will also overflow to both ends in the length direction of the four side frames 1. By additionally providing the through grooves 12 in the U-shaped groove, the waterproof effect can be further improved.

[0033] In this embodiment, the cross-section of the placement groove 11 is trapezoidal in reverse, and the wide side is at the end close to the tempered glass 2. When pouring, in order to ensure that the amount of the semi-fluid silicone overflowing from both ends of the placement groove 11 is consistent, it is set in a trapezoidal shape in reverse. When the semi-fluid silicone overflows from the placement groove 11, the inclined surfaces at both ends will reduce the overflow speed, so that it is convenient for the staff to adjust, and the amount of the semi-fluid silicone flowing out from both ends of the placement groove 11 is kept consistent through manual intervention, thereby ensuring the same sealing performance at both ends.

[0034] In this embodiment, an abutting groove 13 is further formed on the U-shaped groove, and a sealing silicone strip is fixedly arranged in the abutting groove 13. Through the elastic compression characteristic of the sealing strip, the tempered glass 2 and the front frame are closely attached to form a secondary seal.

[0035] In this embodiment, the corner connector 3 is composed of a pair of vertically connected connecting blocks 31. Connecting grooves are formed at the ends of the side frames 1, and the connecting blocks 31 and the connecting grooves are inserted. Through the vertically connected connecting blocks 31, the side frames 1 are connected together by an insertion method, improving the convenience during assembly and installation.

[0036] In this embodiment, bumps 32 for blocking water vapor are provided at both ends of the connecting block 31. The bumps 32 are fixedly connected to the connecting block 31 and are made of rubber. After the connecting block 31 is inserted into the connecting groove on the frame 1, the provision of the bumps 32 increases the sealing performance between the frame 1 and the frame 1.

[0037] In this embodiment, multiple groups of bumps 32 are provided and are spaced apart on the connecting block 31. By providing multiple groups of bumps 32 on the connecting block 31 and spacing them apart on the connecting block 31, after the connecting block 31 is inserted into the insertion slot 14, the sealing performance between the frames 1 can be further improved through the blocking of the multiple groups of bumps 32.

[0038] In this embodiment, sealant for increasing the sealing performance is applied between the bumps 32. During assembly, the sealant is first applied to the surface of the bumps 32, and then the bumps 32 are inserted into the through groove 12 of the frame 1. The sealant cures and forms a connection structure with the through groove 12 of the frame 1 in the groove beside the bumps 32, playing a role in waterproofing and structural strengthening.

[0039] Specific implementation process: The assembly consists of four frames 1 and tempered glass 2 placed therebetween. The frame 1 is specially provided with an asymmetric U-shaped groove to firmly clamp the tempered glass 2. During the assembly process, a semi-fluid viscous silicone body is first injected into the placement groove 11 of the U-shaped groove, and then the tempered glass 2 is pushed in. After being squeezed, the silicone body not only fills the gap but also overflows to both ends of the frame 1 and merges with the corner connector 3, and forms a strong waterproof barrier after curing.

[0040] The innovative design of the U-shaped groove includes a through groove 12 with an irregular shape, which effectively guides the flow of the excess silicone body and further improves the waterproof performance. The trapezoidal cross-section design of the placement groove 11 is ingenious, ensuring that the overflow amount of the silicone body is uniform and controllable, and facilitating manual adjustment to achieve consistent sealing performance at both ends. In addition, a sealing silicone strip is also provided in the U-shaped groove. Utilizing its elastic compression characteristics, it closely adheres to the tempered glass 2 to achieve secondary sealing and enhance the waterproof effect.

[0041] The corner connector 3 adopts a design of a connecting block 31 with a vertical connection, and is quickly combined with the connecting groove at the end of the frame 1 through a plug-in method, simplifying the assembly process and improving the installation efficiency. The rubber bumps 32 assembled at both ends of the connecting block 31 not only enhance the sealing performance between the frames 1, but also form a multiple water vapor blocking layer through the design of multiple groups of spaced distribution, comprehensively improving the waterproof performance.

[0042] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
