[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0023] See also Figures 1 to 4 In this embodiment, a display circuit board mounting structure is provided, including a base plate 1, wherein slide grooves 4 are provided on both sides of the upper portion of the base plate 1, and a plurality of heat dissipation plates 3 are fixedly connected to one side of the slide grooves 4 above the base plate 1, wherein a plurality of positioning members 5 are slidably connected inside the slide grooves 4, and a circuit board body 2 is mounted between the positioning members 5;

[0024] The positioning member 5 includes a sliding member 51, a pressing groove 52 is provided on one side of the upper side of the sliding member 51, and a limiting plate 53 is fixedly connected to the other side of the sliding member 51. The limiting plate 53 can be located between the heat dissipation plate 3;

[0025] A connecting plate 8 is provided below the base plate 1 , and the lower end of the sliding member 51 passes through the connecting plate 8 and is slidably connected to the connecting plate 8 . A rotating rod 9 is provided between the connecting plate 8 and the base plate 1 , and a cam 91 is fixedly connected to the rotating rod 9 .

[0026] During use, by designing a connecting plate 8 and a positioning member 5, the positioning member 5 can be lowered through the connecting plate 8 to fix the circuit board body 3 on the base plate 1. During disassembly, multiple positioning members 5 can be loosened at the same time by bringing the connecting plate 8 close to the base plate 1, thereby facilitating the removal of the circuit board body 3.

[0027] By designing the heat sink 3 and the positioning member 5, the heat sink 3 can increase the upper surface area of the base plate, thereby improving the heat dissipation capacity of the base plate. The heat sink 3 can limit the limit plate 53, thereby limiting the sliding member 51 forward and backward, so that the positioning member 5 can be installed at different positions on the heat sink 3, thereby changing the installation position of the circuit board body 2, thereby maintaining a larger space between the circuit board and the surrounding components, and improving the heat dissipation effect.

[0028] In further embodiments, see Figure 2 The bottom of the base plate 1 is recessed inward to form an inner groove 6. A connecting plate 8 is located within the inner groove 6. A plurality of heat sinks 7 are fixedly connected to the inner groove 6 and around the connecting plate 8. The heat sinks 7 increase the external leakage area below the base plate 1, thereby improving the heat dissipation effect of the base plate 1. Heat is conducted through the base plate 1, thereby improving the heat dissipation effect of the circuit board body 2.

[0029] In further embodiments, see Figure 2 、 4The rotating rod 9 is rotatably connected to the connecting plate 8. The cam 91 has an elliptical cross-section. Connecting ports 93 are provided at both ends of the rotating rod 9. A torsion plate 92 is slidably connected to the interior of the connecting port 93. When the rotating rod 9 rotates, the cam 91 is driven to rotate together. When the longer ends of the cam 91 are horizontal, the gap between the connecting plate 8 and the bottom plate 1 can be reduced, the connecting plate 8 can be raised, and the positioning member 5 can be raised. The pressing groove 52 prevents the circuit board body 2 from being pressed against the bottom plate 1, allowing the circuit board body 2 to be removed. When the longer ends of the cam 91 are vertical, the gap between the connecting plate 8 and the bottom plate 1 is maximized. The connecting plate 8 thus pulls the positioning member 5 to press the circuit board body 2 against the bottom plate 1. The torsion plate 92 facilitates the user to apply force, thereby driving the rotating rod 9 to rotate.

[0030] In further embodiments, see Figures 1-2 4. Insertion openings are provided on the front and rear sides of the base plate 1, located above the rotating rod 9, into which a torsion plate 92 can be inserted. After the torsion plate 92 is rotated and inserted into the insertion opening, the rotation of the torsion plate 92 is restricted. The torsion plate 92, in turn, restricts the rotation of the rotating rod 9, thereby maintaining the position of the cam 91. This ensures a constant spacing between the bottom of the base plate 1 and the connecting plate 8, thereby stably pressing the circuit board body 2 onto the base plate 1.

[0031] In further embodiments, see Figures 1-2 The heat sinks 1 and 3 are spaced apart. The spacing is the same width as the limiting plate 53, and the thickness of the limiting plate 53 is less than the maximum spacing between the connecting plate 8 and the bottom plate 1. This ensures that the limiting plate 53 does not wobble when stuck between the heat sinks 1 and 3, and that the limiting plate 53 can be separated from the heat sink 1 after the connecting plate 8 rises, thereby allowing the circuit board body 2 to be removed.

[0032] In further embodiments, see Figure 3 The grooves 52 match the corners of the circuit board body 2. The grooves 52 limit the corners of the circuit board body 2, ensuring maximum exposure of the sides of the circuit board body 2, so that the multiple interfaces on the circuit board body 2 are not blocked (the display circuit board includes multiple interfaces for power supply and data transmission. Limiting the corners will not block the interfaces).

[0033] In further embodiments, see Figures 1-2 The bottom plate 1 is provided with mounting holes at the four corners, and a plurality of heightening pads are provided below the bottom plate 1 below the mounting holes. By adding the pads, the space below the bottom plate 1 is ensured, and the heat dissipation capacity is improved.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
