DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Example 1
[0031] A LED display screen controller, such as Figure 1-Figure 5 As shown, it includes a controller housing 1, a front panel 2 installed on the front side of the controller housing 1, and a fixed plate 3 and a circuit board 4 arranged inside the controller housing 1. The fixed plate 3 is fixedly connected to the upper surface of the circuit board 4. A panel slot 5 is provided on the front of the front panel 2. A rotatable rotating member 6 is provided at a position corresponding to the panel slot 5 inside the controller housing 1. The rotating member 6 is a triangular prism, and its three sides are respectively a functional panel 7, a protective panel 8 and a bottom surface connected to a rear cable 15. The end of the rear cable 15 away from the rotating member 6 is electrically connected to the circuit board 4. Both ends of the rotating member 6 are connected to a rotating shaft 9. The rotating shaft 9 is a cylinder and has a fan-shaped notch arranged in its circumferential direction. A connecting block 10 is connected to the inner side of the front panel 2 corresponding to the position of the two groups of rotating shafts 9. A rectangular groove is provided on the opposite side of the two groups of connecting blocks 10. A moving block 11 that can slide in the groove is connected in the groove. The moving block 11 is connected to the inner wall of the front panel 2 through a tension spring 12. A cylindrical groove is provided on the opposite side of the two groups of moving blocks 11, and a fan-shaped protrusion is arranged in the groove.
[0032] The rotating shaft 9 is movably connected to the limiting hole 13. The connection between the rotating shaft 9 and the limiting hole 13 is as follows: Figure 4 shown.
[0033] By setting the rotating member 6, the function panel 7 is distributed on one of the surfaces of the rotating member 6, and the entire rotating member 6 is gently pushed toward the inside of the controller housing 1 for a certain distance. At this time, the rotating member 6 falls off and is squeezed against the inner wall of the front panel 2 to achieve free rotation. When the function panel 7 is rotated to face the front side, it can be used to connect various video output cables and control the device. When the protective panel 8 is rotated to face the front side, the function panel 7 is placed inside the entire device. The protective panel 8 can make the appearance of the entire device appear neater when not in use, and when the device is not in use, the function panel 7 is rotated to the inside of the device to protect all interfaces. Due to the matching connection between the rotating shaft 9 and the limiting hole 13, the rotation range of the rotating member 6 is within one hundred and twenty degrees, thereby ensuring that the bottom surface of the rotating member 6 connected to the rear cable 15 will not flip to the front side. When the rotation of the rotating member 6 is completed, the squeezing force on the rotating member 6 is released, and the moving block 11 drives the rotating member 6 to move and squeeze the wall position of the front panel 2 through the rotating shaft 9 under the pulling force of the tension spring 12, completing the entire action.
[0034] A rubber ring 14 is installed on the inner wall of the front panel 2. Due to the activity of the rotating member 6, the addition of the rubber ring 14 can improve the sealing performance of the panel groove 5 when the rotating member 6 squeezes the inner wall of the front panel 2.
[0035] Example 2
[0036] Based on the above embodiments, Figure 6 to Figure 7 As shown, a rectangular aluminum alloy frame 16 is installed inside the front panel 2, and two groups of soft heat-conducting media 17 are installed inside the aluminum alloy frame 16. The soft heat-conducting medium 17 is flame-retardant conductive foam. The soft heat-conducting medium 17 wraps the upper and lower surfaces of the circuit board 4, and rectangular gaps are opened on the opposite surfaces of the two groups of soft heat-conducting media 17. Heat-conducting plates 18 are installed at the upper and lower ends of the aluminum alloy frame 16, and the ends of the two groups of heat-conducting plates 18 close to the soft heat-conducting medium 17 are inserted into the gaps on the surface of the soft heat-conducting medium 17. The outer surface of the controller housing 1 is provided with cavity-shaped heat dissipating fins 19, and the opposite sides of the two groups of heat-conducting plates 18 are inserted into the inside of the heat dissipating fins 19.
[0037] By setting up two groups of soft thermal conductive media 17, the front and back sides of the entire circuit board 4 can be wrapped with the maximum area, which can greatly improve the heat conduction efficiency during heat dissipation, and the soft thermal conductive medium 17 is fixed by the aluminum alloy frame 16. The two groups of soft thermal conductive media 17 can also play a buffering role when wrapping the circuit board 4, thereby protecting the circuit board 4. The thermal conductive sheet 18 is inserted into the gap of the soft thermal conductive medium 17 to increase the contact area between the two and improve the efficiency of heat conduction. The thermal conductive sheet 18 is in contact with the outside air through the heat dissipation fins 19 to achieve efficient heat dissipation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
