[0024] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0025] As Figures 1-4 shown, the present application provides a circuit board, comprising an installation assembly 1, the installation assembly 1 has an installation plate 11, and the installation plate 11 is provided with a through groove (not marked in the figure), and three groups of support base plates 12 are connected between the inner walls of the through groove, and support side plates 15 are fixed between the inner walls of the through groove, two groups of symmetrical placement grooves 16 are provided on the two groups of support side plates 15, and the placement grooves 16 and the support base plates 12 are matched with each other to jointly enclose a space for placing the circuit board;

[0026] And four sets of supporting legs 14 are fixedly installed on the bottom surface of the mounting plate 11, which are used to provide support for the mounting plate 11, so that the lower end of the circuit board has a heat dissipation space, and a plurality of supporting portions 13 are fixedly installed on the supporting base plate 12, which are used to support the circuit board, so that the circuit board has a certain distance from the supporting base plate 12, so as to facilitate heat dissipation;

[0027] It should be noted that when the circuit board is placed on the supporting portion 13 of the supporting base plate 12, the two ends of the circuit board are simultaneously placed in the placing groove 16, so as to provide initial limitation for the circuit board and preliminarily limit the position of the circuit board in the horizontal direction, preventing the circuit board from being deviated left and right or forward and backward during installation;

[0028] Meanwhile, two sets of fixing assemblies 2 are symmetrically installed on the mounting plate 11, which include a fixing seat 21 fixedly installed on the mounting plate 11, and the fixing seat 21 has a protruding portion 22, and a penetrating rod 23 is movably penetrated through the protruding portion 22, one end of the penetrating rod 23 is fixedly installed with a pressing portion 25, the pressing portion 25 is inverted L-shaped, and a first spring 24 is connected between the pressing portion 25 and the fixing seat 21, and the first spring 24 is sleeved on the penetrating rod 23;

[0029] In the default state, the first spring 24 is in the compressed state, and generates a spring force in the direction of the circuit board. When the circuit board is placed, the pressing portion 25 is close to the circuit board under the action of the spring force and is pressed at the four corner positions, and a semi-convex ball 26 is fixedly installed on the horizontal surface of the pressing portion 25 close to the circuit board, the semi-convex ball 26 is of flexible material, and a through hole is adapted to be formed at the four corner positions of the circuit board, when the pressing portion 25 presses the circuit board, the semi-convex ball 26 will be extruded and deformed to a certain extent, so as to be smoothly buckled in the through hole. The cooperation of the semi-convex ball 26 and the through hole utilizes the elastic deformation and friction of the flexible material to fix the circuit board in the vertical direction and prevent the circuit board from moving up and down;

[0030] And a heat dissipation assembly 3 is installed at the bottom of the mounting plate 11, which includes two sets of guide rails 31 fixedly installed at the bottom of the mounting plate 11, and two sets of sliding blocks 32 are slidably installed on the guide rails 31, the sliding blocks 32 are adapted to slide along the straight line direction of the guide rails 31, and a connecting plate 33 is connected between the two sets of sliding blocks 32, the connecting plate 33 has two sets of fixing plates (not marked in the figure), and a heat dissipation fan 36 is installed on the bottom surface of the fixing plate, the heat dissipation fan 36 is connected with the fixing plate through a second spring 37, and a through slot 34 is formed in the fixing plate;

[0031] The second spring 37 provides a buffering effect. When the heat dissipation fan 36 works and generates vibration, the spring can absorb part of the vibration energy, reducing the vibration transmission to the fixed plate and the entire mounting plate 11. The through slot 34 opened on the fixed plate, on the one hand, reduces the weight of the fixed plate, and on the other hand, can help air circulation, improving heat dissipation efficiency. When the heat dissipation fan 36 works, the motor drives the fan blade to rotate, forcing air flow, taking away the heat emitted by the circuit board, and realizing the heat dissipation function;

[0032] And a pull rod 35 is fixedly installed on the side of the connecting plate 33, which can conveniently and quickly pull out or push back the heat dissipation fan 36 from the guide rail 31; (It should be noted that a fastener can be connected on the sliding block 32, so that when the sliding block 32 moves to the specified position, it can be fixed on the mounting plate 11 by the fastener);

[0033] At the same time, the design of the guide rail 31 and the sliding block 32 makes the position of the heat dissipation fan 36 flexible to adjust according to the heat generation situation of different areas of the circuit board. For some areas on the circuit board where heat is concentrated, the heat dissipation fan 36 can be moved to the area below, so as to targetedly strengthen heat dissipation and improve the accuracy and effectiveness of heat dissipation effect.

[0034] In summary: the circuit board of the present application is stable in installation, the placing groove 16 cooperates with the support base plate 12 to provide initial horizontal restriction for the circuit board, effectively avoiding the deviation of the circuit board during installation, and the fixed assembly 2 drives the pressing part 25 by the spring force, and realizes firm fixing in the vertical direction by the buckling of the semi-convex ball 26 and the through hole of the circuit board, thereby improving the stability of the circuit board installation and ensuring that it can maintain stable position under various working conditions.

[0035] The heat dissipation performance is outstanding, the support leg 14 suspends the mounting plate 11, and a heat dissipation space is constructed below it, and the support part 13 forms a gap between the circuit board and the support base plate 12, which is beneficial to air convection. The heat dissipation fan 36 in the heat dissipation assembly 3 actively forces air flow, quickly taking away the heat of the circuit board, the second spring 37 buffers the working vibration of the heat dissipation fan 36, reducing the adverse effects on the circuit board, the through slot 34 on the fixed plate further optimizes air circulation and reduces weight, and the heat dissipation fan 36 can be flexibly adjusted in position according to the heat generation area of the circuit board, realizing precise and efficient heat dissipation, ensuring that the circuit board is always in a suitable temperature environment, and prolonging the service life.

[0036] The maintenance convenience is also remarkable, the pull rod 35 enables the heat dissipation fan 36 to be conveniently and quickly pulled out or pushed back from the guide rail 31, facilitating cleaning, maintenance and replacement operations, and the fastener on the sliding block 32 ensures that the heat dissipation fan 36 can be accurately positioned and fixed at the best heat dissipation position, greatly improving the maintenance efficiency and reducing the maintenance cost, thereby providing a strong guarantee for the long-term stable operation of the circuit board.

[0037] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
