[0002] Matrix LED displays are a type of display that cleverly combines LED technology, interactive technology, and matrix design. Matrix LED displays consist of numerous independent LED lamps arranged in a matrix. These LED lamps are the basic units of the display. By controlling the on and off states of each lamp, various images, text, videos, and other information are presented. To ensure that all LED lamps can display the information as needed, they need to be scanned row by row or column by column. By rapidly switching the selection signals for each row or column, LED lamps in different positions are illuminated one by one, and the human eye's persistence of vision is utilized to ensure that people see a complete and stable image.

[0003] The above-mentioned and existing technologies have the following defects: Due to the particularity of the matrix structure, the requirements for installation accuracy are high.

[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figure 1-Figure 5 As shown, the utility model provides a matrix LED display device, including an integrated board 1, a plurality of lamp beads 2 are mounted on the surface of the integrated board 1, and an auxiliary device 3 is provided on the surface of the integrated board 1.

[0031] The specific setting and function of the auxiliary device 3 will be described in detail below.

[0032] like Figure 2-Figure 5As shown, the auxiliary device 3 includes two limit grooves 301, and the two limit grooves 301 are both opened on the surface of the integrated board 1. The surface of the limit groove 301 is slidably connected to the limit rod 302, and the surface of the limit rod 302 is fixedly connected to the heat dissipation plate 303, and the surface of the heat dissipation plate 303 is fixedly connected to two fixed plates 307. The surfaces of the two fixed plates 307 are slidably connected to the pins 305. The surface of the integrated board 1 is fixedly connected to two connecting frames 304, and the two connecting frames 304 are both snap-fitted with the fixed plates 307. The arc surface of the pin 305 is covered with a spring 306, and the two ends of the spring 306 are fixedly connected to the pin 305 and the connecting frame 304 respectively. There are several heat sinks 308 fixedly connected, and the cross section of the limiting groove 301 is "C"-shaped. The two limiting rods 302 on the heat sink 303 are inserted into the limiting groove 301. At this time, the limiting groove 301 with a "C"-shaped cross section can make the limiting rod 302 easily slide into or snap into the limiting groove 301, without the need for complicated alignment operations, which greatly improves the installation efficiency. A protective pad 309 is fixedly connected to the surface of the limiting groove 301. The protective pad 309 is a rubber pad. When the limiting rod 302 enters the bottom end of the limiting groove 301, it will squeeze the protective pad 309 in the limiting groove 301. At this time, the protective pad 309 made of rubber material can ensure that one end of the limiting rod 302 is aligned with the limiting groove The contact surface at the bottom end of 301 is protected, and the arc surface of the limit rod 302 is fixedly connected with an anti-slip pad 310, and the anti-slip pad 310 is slidably connected to the limit groove 301. The limit rod 302 will drive the anti-slip pad 310 to move in the same direction. At this time, the anti-slip pad 310 can increase the friction between the contact surface of the limit rod 302 and the limit groove 301, preventing the limit rod 302 from shaking in the limit groove 301. One end of the limit rod 302 is fixedly connected with an auxiliary rod 311, and the auxiliary rod 311 is clamped with the integrated board 1. Pull the auxiliary rod 311 in the direction away from the integrated board 1, and then the auxiliary rod 311 will drive the two limit rods 302 along the arc of the limit groove 301 The surface moves in the same direction. At this time, the auxiliary rod 311 can easily pull up the limit rod 302. An auxiliary groove 312 is provided on the surface of the integrated board 1. The cross section of the auxiliary groove 312 is semicircular. Put your finger into the auxiliary groove 312 and pinch the auxiliary rod 311. At this time, the auxiliary groove 312 with a semicircular cross section can touch the auxiliary rod 311. One end of the pin 305 is fixedly connected to a sharp cone 313. The sharp cone 313 is a stainless steel cone. The pin 305 will drive the sharp cone 313 to move towards the direction close to the connecting frame 304 and the fixing plate 307 under the action of the elastic force of the spring 306 itself. At this time, the sharp cone 313 can facilitate the pin 305 to pass through the connecting frame 304 and the fixing plate 307.

[0033] The overall working principle is that when the lamp bead 2 on the integrated board 1 is in operation and the radiator is damaged and needs to be replaced, the two latches 305 are first pulled away from the integrated board 1, and then the latch 305 drives one end of the spring 306 to move. At this time, the spring 306 itself will generate a retraction tension, and then the latch 305 is separated from the connecting frame 304 on the integrated board 1 and the fixing plate 307 on the heat sink 303. Then, the finger is inserted into the auxiliary groove 312 to pinch the auxiliary rod 311. At this time, the auxiliary groove 312 with a semicircular cross section can touch the auxiliary rod 311. Then, the auxiliary rod 311 is pulled away from the integrated board 1, and then the auxiliary rod 311 drives the two limit rods 302 along the limit rods. After the fins 308 are in a state of being moved in a predetermined direction, the fins 307 are in a state of being moved in a predetermined direction, and the fins 307 are in a state of being moved in a predetermined direction. When the locking cam 305 is in the unlocked position, the locking cam 305 is in the unlocked position, and the locking cam 305 is in the unlocked position, so that the locking cam 305 is locked. 4 and the position of the fixing plate 307 are limited. By setting the auxiliary device 3, the cooperation between the limiting groove 301, the limiting rod 302, the heat sink 303, the connecting frame 304, the pin 305, the spring 306, the fixing plate 307 and the heat sink 308 is utilized to quickly replace the heat sink 308, thereby avoiding the high requirement on installation accuracy due to the particularity of the matrix structure. A slight deviation may cause poor heat dissipation or a negative impact on the display effect. After replacing the heat sink 308, it is necessary to ensure that its installation position is accurate and fits tightly with components such as the LED chip, otherwise it will affect the heat dissipation effect, thereby improving the installation accuracy when replacing the heat sink 308 and further improving the fit between the heat sink 308 and the integrated board 1.
