DETAILED DESCRIPTION

[0026] The specific embodiments of the utility model are further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0027] "Top surface" "bottom" "bottom surface" take the normal use state of the panel antenna as reference, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0028] As shown in Figures 1-3 A kind of panel antenna for impact-resistant liquid crystal display screen, including rectangular mainboard 1, signal line 2 is welded and connected on mainboard 1, further including mounting hole 101, it is set along the thickness direction of mainboard 1 and penetrates mainboard 1, mainboard 1 has four corner parts, and mounting hole 101 is arranged at corner part;Buffering member 3, including L-shaped buffer strip 301, buffer strip 301 has elasticity and is wrapped around corner part, buffer strip 301 integrally formed and connected with two elastic buffer rings 304, two buffer rings 304 are located at the two sides of mainboard 1 respectively, and are coaxially arranged with mounting hole 101;Connecting piece 4, two buffer rings 304 are detachably connected with mounting hole 101 by connecting piece 4.

[0029] The above-mentioned panel antenna has strong impact resistance, and can effectively resist external impact force during storage, transportation and installation on the liquid crystal display screen to protect itself and reduce damage;The four corner parts of the antenna are provided with buffering members 3, which are detachably connected by connecting pieces 4 to facilitate replacement of the buffering members 3;Buffering member 3 includes buffer strip 301 and buffer ring 304, both of which are made of rubber material, which has good elasticity to achieve good buffering effect. Buffer strip 301 is arranged at the corner of mainboard 1 along the extension direction of the side edge of mainboard 1 to protect the corner of mainboard 1 which is easy to be damaged. By lengthening the length of buffer strip 301, the side edge of mainboard 1 can also be protected, the impact resistance of the antenna is improved, and the probability of damage to the antenna is reduced. Buffer ring 304 is arranged on both sides of mainboard 1, which can support both sides of mainboard 1 after installation and during transportation, and absorb impact force by its elasticity to protect mainboard 1, further improve the impact resistance of mainboard 1, and reduce the probability of damage to mainboard 1.

[0030] Compared with the way of wrapping the mainboard 1 in the circumferential direction, the four independent buffering members 3 of the antenna are arranged at the four corners of the mainboard 1, so that the installation of the buffering members 3 is not limited by the size of the mainboard 1, and the convenience of using the buffering members 3 is improved.

[0031] Further improvement is, asFigure 4 As shown, the inner side of the buffer strip 301 is provided with a limiting groove 302 along the extending direction thereof, and the limiting groove 302 is inserted and matched with the side edge of the main plate 1. The limiting groove 302 and the edge of the main plate 1 are limited to each other, which can improve the firmness of the connection between the buffer strip 301 and the main plate 1, reduce the probability of dislocation or displacement of the buffer strip 301, and ensure the protection effect of the buffer strip 301 on the main plate 1. Moreover, after the side edge of the main plate 1 enters the inside of the limiting groove 302, the buffer strip 301 can be extended and wrapped to the side surface of the main plate 1, thereby improving the protection effect on the main plate 1.

[0032] Further improvement is that, as shown in Figure 4 As shown, the opposite side surfaces of the two buffer rings 304 are coaxially and integrally provided with inner bushings 306, and the inner bushings 306 are arranged inside the mounting hole 101. When the antenna is mounted on the liquid crystal display screen, the bolt assembly can pass through the mounting hole 101 to achieve the fixed mounting between the antenna and the liquid crystal display screen. The inner bushing 306 and the buffer ring 304 are an integral whole, the inner bushing 306 is made of rubber material, and the arrangement of the inner bushing 306 can protect the inner circumferential surface of the mounting hole 101 and reduce the wear of the mounting hole 101. Meanwhile, the inner bushing 306 can also play a certain energy absorption role to reduce the impact force transmitted to the main plate 1 through the bolt assembly and improve the impact resistance of the main plate 1.

[0033] Further improvement is that, as shown in Figure 5 As shown, the opposite side surfaces of the two buffer rings 304 are coaxially and integrally provided with outer limiting rings 305 and inner limiting rings 307, respectively, and the inner diameter of the outer limiting ring 305 is greater than or equal to the outer diameter of the inner limiting ring 307. The outer limiting ring 305 and the inner limiting ring 307 are an integral whole with the buffer ring 304 and are made of rubber material. When the antennas are stored or transported, a plurality of antennas are usually stacked together. Through the arrangement of the inner limiting ring 307 and the outer limiting ring 305, the inner limiting ring 307 of one antenna and the outer limiting ring 305 of another antenna can be inserted into each other when the antennas are stacked, thereby playing a mutual limiting role between the two antennas, improving the stability of the stacked antennas, and reducing the probability of damage to the antennas. Moreover, the elasticity of the inner limiting ring 307 and the outer limiting ring 305 can also absorb the impact force, thereby further improving the impact resistance of the antennas. After the antennas are mounted on the liquid crystal display screen, the inner limiting ring 307 and the outer limiting ring 305 are located between the antennas and the mounting surface, thereby playing a buffering role, ensuring that the antennas have good impact resistance in different use scenarios, and reducing the probability of damage to the antennas.

[0034] Further improvement is that, as shown in Figure 6As shown, the connecting piece 4 comprises internally threaded sleeve 401 and externally threaded sleeve 402 which are screwed together, and the ends of the internally threaded sleeve 401 and the externally threaded sleeve 402 are each provided with a flange 403 in the circumferential direction. After the internally threaded sleeve 401 and the externally threaded sleeve 402 are screwed together, they pass through the mounting hole 101 and the buffer ring 304, and the flange 403 abuts against the buffer ring 304 and the main plate 1 from both sides, thereby achieving the fixed installation of the buffer ring 304 and the buffer strip 301 on the main plate 1. The internally threaded sleeve 401 and the externally threaded sleeve 402 which are screwed together are convenient to disassemble and assemble, thereby improving the convenience of disassembling and assembling between the buffer piece 3 and the main plate 1. When the antenna is installed to the liquid crystal display, the bolt assembly passes through from the inside of the internally threaded sleeve 401, thereby separating the bolt assembly and the antenna through the internally threaded sleeve 401, so as to reduce the wear of the antenna.

[0035] Further improvement is that, as shown in the drawings, Figure 5 The two buffer rings 304 are provided with an inner recess 308 on the side surface opposite to each other, and the flange 403 can enter the inner recess 308, and the depth of the inner recess 308 is greater than the thickness of the flange 403. The inner recess 308 receives the flange 403 inside, which can prevent the hard flange 403 from colliding with the mounting surface of the liquid crystal display or other antennas, thereby reducing the probability of damage caused by the flange 403 to other devices, and improving the practicability of the antenna.

[0036] Further improvement is that, as shown in the drawings, Figure 6 The outer periphery of the flange 403 is a regular hexagonal structure. The flange 403 with the hexagonal structure can be matched with the commonly used socket wrench, thereby facilitating the rotation of the internally threaded sleeve 401 and the externally threaded sleeve 402 through the socket wrench, improving the convenience of disassembling and assembling between the buffer piece 3 and the main plate 1, and further improving the production efficiency of the antenna.

[0037] Further improvement is that, as shown in the drawings, Figure 4 The two ends of the buffer strip 301 are provided with a wire clamping groove 303, and the width of the slot of the wire clamping groove 303 is smaller than the width inside the wire clamping groove 303. The provision of the wire clamping groove 303 can position the signal line 2, facilitate the wiring or storage of the signal line 2, and further improve the convenience of use, transportation or storage of the antenna.
