[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] Reference Figures 1-4 The present invention provides an embodiment of an LED display screen with a pin protection function, comprising an LED display screen body 1, wherein the LED display screen body 1 comprises a front frame 101, an intermediate frame 105, and a rear shell 106. The front frame 101, the intermediate frame 105, and the rear shell 106 are connected as a whole by screws. A circuit board 104 is installed in the intermediate frame 105 through a locking frame 103. The circuit board 104 comprises a circuit board, an LED lamp, a driver IC, a resistor, and a capacitor. The circuit board 104 is used to display the required pattern. Support blocks are fixedly connected to the corners of the intermediate frame 105. 1051, the corners of the circuit board 104 are in contact with the support block 1051. There are two locking frames 103, which are axially symmetrical. The cross-section of the locking frame 103 is L-shaped. An elastic gasket is fixedly connected to the side of the locking frame 103 close to the circuit board 104. The elastic gasket is used to provide protection for the front side of the circuit board 104 to ensure that the circuit board 104 can be used normally. A transparent plate 102 is installed between the middle frame 105 and the front frame 101. The transparent plate 102 is used to provide protection for the LED lamp. The rear of the middle frame 105 is fixedly connected to the force frame 1052.
[0023] The force-bearing frame 1052 is provided with a stabilizing member 2, and the stabilizing member 2 includes a mounting frame 202, and the mounting frame 202 is installed on the force-bearing frame 1052 by installing screws 201. The mounting frame 202 is fixedly connected to a spring 203 on a side close to the force-bearing frame 1052, and the spring 203 is fixedly connected to a slide 204 on an end away from the mounting frame 202. The slide 204 passes through the force-bearing frame 1052 and is slidably connected to each other. The slide 204 is fixedly connected to a pressing piece 205 on an end away from the mounting frame 202. The pressing piece 205 is circular in shape, and is fixedly connected to an insulating gasket on a side close to the circuit board 104. The insulating gasket is used to provide insulation protection for the pressing piece 205 to ensure that the circuit board 104 can be used normally, and the pressing piece 205 is in contact with the circuit board 104.
[0024] During use, when the rear shell 106 is hit, the force generated by the collision will first contact the force-bearing frame 1052, and then be transferred to the middle frame 105, thereby preventing the internal circuit board 104 from being subjected to the impact force. Secondly, the spring 203 after installation is in a slightly compressed state, and therefore, it can provide support force to the slide 204 and the pressing plate 205 toward one side of the circuit board 104, thereby ensuring the stability of the circuit board 104. The front of the circuit board 104 is restricted by the support block 1051, thereby ensuring the stability of the circuit board 104 and improving the overall durability. By setting the middle frame 105 and the force-bearing frame 1052, when the rear shell 106 is hit, the force can be transferred to the force-bearing frame 1052 and the middle frame 105, thereby preventing the circuit board from being directly deformed by the force, thereby improving the overall durability. In addition, the stabilizing member 2 provided can provide a certain support force to the circuit board, ensuring the stability of the circuit board, without affecting the normal use of the whole.
[0025] Working principle: During use, when the rear shell 106 is hit, the force generated by the collision will first contact the force-bearing frame 1052, and then be transmitted to the middle frame 105, to prevent the internal circuit board 104 from being subjected to impact force. Secondly, the spring 203 after installation is in a slightly compressed state. Therefore, it can provide support force to the slide 204 and the pressing piece 205 toward one side of the circuit board 104, ensuring the stability of the circuit board 104. The front of the circuit board 104 is restricted by the support block 1051, thereby ensuring the stability of the circuit board 104 and improving the overall durability.
[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
