DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] Embodiment: The utility model provides an integrated driving motherboard for an LED display unit, such as Figure 1 As shown, it includes a shell 1, a cover plate 2 is provided on the upper surface of the shell 1, a rotating device 5 is installed on one side of the cover plate 2, a skateboard buckle 3 is fixedly installed on one side of the shell 1, and a skateboard groove 4 is provided on the other side of the shell 1, the skateboard buckle 3 is adapted to the skateboard groove 4, a mainboard is provided in the shell 1, and an LED lamp 16 is provided on the mainboard; wherein the shell 1 and the cover plate 2 are set to transparent plastic materials, and each mainboard has an 8-shaped splicing of LED lights 16, and when the number of digits to be displayed is determined, the integrated drive mainboard can be spliced, and the two drive mainboards can be spliced ​​together by sliding the skateboard buckle 3 on one shell 1 from the top of the skateboard groove 4 of another shell 1, so that the splicing can be carried out according to the required number of digits, and the maximum value of the displayed digits can be changed at will.

[0021] like Figure 2-3As shown, through holes 15 are provided at the four corners of the main board, a plurality of second fixing columns 17 are fixedly installed at the bottom of the housing 1, and a third cylindrical groove 18 is provided at the top of each of the second fixing columns 17. The main board is placed on the upper surface of the plurality of first fixing columns 7, and the through holes 15 are connected to the third cylindrical grooves 18. A plurality of first fixing columns 7 are provided on the lower surface of the cover plate 2, and a plurality of first cylindrical grooves 11 are provided at the bottom of the plurality of first fixing columns 7. A first spring 10 is provided in each of the plurality of first cylindrical grooves 11, and one end of each of the first springs 10 is connected to the top of the first cylindrical groove 11. Fixedly connected, the other end of each of the first springs 10 is fixedly connected to the first telescopic column 8, and a pressure plate 9 is fixedly sleeved on each of the first telescopic columns 8. The first telescopic column 8 is adapted to the third cylindrical groove 18; when the cover plate 2 is covered, the first telescopic column 8 will pass through the through hole 15 and extend into the third cylindrical groove 18 until the pressure plate 9 presses the main board and continues to cover the cover plate 2. At this time, the first spring 10 will be compressed. The compression of the first spring 10 makes the first spring 10 have elastic force on the first telescopic column 8, and then the pressure plate 9 produces a certain pressure on the main board, so that the main board can be firmly fixed inside the shell 1.

[0022] like Figure 3 and Figure 5 As shown, a symmetrical second cylindrical groove 12 is provided in the slide groove 4, and a second spring 13 is arranged in each of the second cylindrical grooves 12. One end of the second spring 13 is fixedly connected to one end of the second cylindrical groove 12, and the other end of the second spring 13 is fixedly connected to the second telescopic column 14. One end of the second telescopic column 14 is provided with an annular bevel 19. Fifth cylindrical grooves 25 are provided on both sides of the slide buckle 3, and the fifth cylindrical groove 25 is adapted to the second telescopic column 14; when it is necessary to connect two shells 1, the slide buckle 3 on one shell 1 is used to slide from the top of the slide groove 4 of the other shell 1. In this process, due to the existence of the annular bevel 19, the second telescopic column 14 will first retract into the second cylindrical groove 12, and then pop out and extend into the fifth cylindrical groove 25 under the action of the elastic force of the second spring 13. In this way, it can be effectively ensured that the connected shells 1 will not be easily detached.

[0023] like Figure 4 and Figure 5As shown, a fourth cylindrical slot 20 is provided at one end of the second telescopic column 14 extending into the fifth cylindrical slot 25, a third spring 21 is arranged in the fourth cylindrical slot 20, one end of the third spring 21 is fixedly connected to the second telescopic column 14, the other end of the third spring 21 is fixedly connected to a conductive copper sheet 22, and a conductive column 23 is fixedly installed in the fifth cylindrical slot 25; when the second telescopic column 14 extends into the fifth cylindrical slot 25, the conductive column 23 extends into the fourth cylindrical slot 20, and the third spring 21 is compressed in the process, and the conductive copper sheet 22 and the conductive column 23 are tightly pressed together by the second spring 13 and the third spring 21, so that current and signals can be transmitted through the conductive column 23 and the conductive copper sheet 22, effectively avoiding the problem of poor contact.

[0024] like Figure 5 As shown, a symmetrical rectangular slope 24 is provided at the bottom of the slide buckle 3; the setting of the rectangular slope 24 ensures that when the slide buckle 3 on one shell 1 slides into the slide groove 4 on another shell 1, they will not be easily stuck to each other. With the rectangular slope 24, this process is easier and smoother.

[0025] like Figure 3 As shown, through slots 6 are provided on both sides of the housing 1; the through slots 6 allow air convection, so that the heat generated by the internal mainboard is continuously dissipated, thereby achieving the purpose of heat dissipation.

[0026] Working principle: Each main board has a digital 8 shape spliced ​​together by LED lights 16. When the number of digits to be displayed is determined, the integrated driver main board can be spliced ​​together. Through the skateboard buckle 3 on one shell 1, slide in from the top of the skateboard slot 4 of another shell 1, and the two driver main boards can be spliced ​​together. In this way, they can be spliced ​​according to the required number of digits. During the splicing process, due to the presence of the annular bevel 19, the second telescopic column 14 will first retract into the second cylindrical slot 12, and then pop out and extend into the fifth cylindrical slot 25 under the action of the elastic force of the second spring 13. When the second telescopic column 14 extends into the fifth cylindrical slot 25, a conductive column 23 will extend into the fourth cylindrical slot 20, and in this process the third spring 21 will be compressed, and the conductive copper sheet 22 and the conductive column 23 are tightly pressed together by the second spring 13 and the third spring 21, so that current and signals can be transmitted through the conductive column 23 and the conductive copper sheet 22.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
