Description

Technical Field

[0001] This utility model relates to the technical field of circuit board mounting structures, specifically a circuit board mounting structure with heat dissipation. Background Technology

[0002] A circuit board is short for printed circuit board. Generally, a printed circuit refers to a conductive pattern, consisting of printed lines, printed components, or a combination of both, fabricated on an insulating material according to a predetermined design. The conductive pattern on the insulating substrate that provides electrical connections between components is called a printed line. Thus, the finished board containing printed circuits or printed lines is called a printed circuit board, also known as a printed board or printed circuit board. During use, electronic components need to be mounted on the circuit board. These components generate heat during operation, and as more and more electronic components are mounted on the circuit board, the heat generated increases. Excessive heat can damage the electronic components, but existing circuit board mounting structures lack heat dissipation mechanisms. After a period of use, they become overheated and easily damaged, limiting their usability.

[0003] In existing technologies, when installing circuit boards, the bottom of the circuit board contacts the surface of the mounting platform. At this time, the heat dissipation effect of the bottom of the circuit board is not ideal, which makes the circuit board prone to high temperature during use. If the high temperature cannot be dissipated in time, it will seriously affect the service life of the circuit board.

[0004] In view of this, this technical solution proposes a circuit board mounting structure with heat dissipation, which can better solve the problems mentioned above. Utility Model Content

[0005] The technical solution adopted by this utility model is as follows: a circuit board mounting structure with heat dissipation, including a support base plate, a circuit board body, and a blower and an exhaust fan for rapid heat dissipation of the circuit board body. The support base plate has a plurality of heat dissipation slots for heat dissipation of the circuit board body. The support base plate has upper mounting ears fixed at the front and rear of the top and lower mounting ears fixed at the front and rear of the bottom. The circuit board body is fixed to the top of the upper mounting ears by upper fixing bolts and the circuit board body is attached to the top of the support base plate.

[0006] The support base plate has fixed rod frames on both the left and right sides, and the fixed rod frames are fixed to the upper and lower mounting ears by connecting plates. The fixed rod frames have limit grooves on both the upper and lower sides, and a reciprocating screw is rotatably installed inside the limit grooves. A servo motor is set in front of the fixed rod frames to drive the reciprocating screw, and the output end of the servo motor is connected to the reciprocating screw. A limit slider is slidably installed inside the limit grooves, and the limit slider is threaded to the reciprocating screw. A movable seat is placed inside the fixed rod frames, and the movable seat is fixedly connected to the limit slider. The blower fan is fixed inside the right movable seat, and the exhaust fan is fixed inside the left movable seat.

[0007] In a preferred embodiment, the upper mounting ear and the lower mounting ear are arranged opposite to each other, and the upper mounting ear and the lower mounting ear are integral with the supporting base plate.

[0008] In a preferred embodiment, the heat dissipation groove has an opening at the top and a closed structure at the bottom.

[0009] In a preferred embodiment, the lower mounting ear is fixed to the desired installation position by a lower fixing bolt.

[0010] In a preferred embodiment, the connecting plate and the fixing rod frame are an integral structure, and the connecting plate is fixed to the upper mounting ear and the lower mounting ear side.

[0011] In a preferred embodiment, a temperature sensor may be installed above one side of the fixed rod frame relative to the circuit board body, and the temperature sensor is electrically connected to the servo motor, the blower fan, the exhaust fan and the external controller.

[0012] In a preferred embodiment, the limiting slider has a threaded hole inside that is adapted to the reciprocating lead screw, and the reciprocating lead screw is threadedly connected in the threaded hole.

[0013] In a preferred embodiment, the interior of the movable base is provided with a through slot for installing a blower fan and an exhaust fan, and the blower fan and exhaust fan are detachably installed in the through slot.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: it facilitates better and faster heat dissipation from the top and bottom of the circuit board body, making the circuit board body less susceptible to damage due to excessive temperature and increasing the service life of the circuit board body.

[0015] 1. In this utility model, the lower mounting ear is installed to the required position by the lower fixing bolt, at which time the position of the support base plate is fixed. Then, the circuit board body is fixed to the upper mounting ear by the upper fixing bolt, so that the circuit board body fits against the top of the support base plate. The heat dissipation grooves opened inside the support base plate can dissipate heat to the bottom of the circuit board body.

[0016] 2. In this utility model, when rapid heat dissipation is required for the circuit board body, the servo motor, blower fan, and exhaust fan are activated. At this time, the servo motor drives the reciprocating screw to rotate inside the limit slide groove. Simultaneously, the reciprocating screw drives the limit slider, moving seat, blower fan, and exhaust fan to reciprocate inside the fixed rod frame. At this time, the blower fan blows the heat generated by the circuit board body to the left, thus dissipating heat from the circuit board body. At the same time, the exhaust fan can quickly expel heat from the circuit board body, thus rapidly dissipating heat from the circuit board body. Attached Figure Description

[0023] The following will combine Figures 1-4 A detailed description is provided of a circuit board mounting structure with heat dissipation according to an embodiment of the present invention.

[0024] refer to Figure 1-3 As shown, a circuit board mounting structure with heat dissipation includes a support base plate 1, a circuit board body 6, and a blower fan 15 and an exhaust fan 16 for rapid heat dissipation of the circuit board body 6. The support base plate 1 has several heat dissipation slots 2 for heat dissipation of the circuit board body 6. The heat dissipation slots 2 are open at the top and closed at the bottom. The support base plate 1 has upper mounting ears 3 fixed at the front and back at the top, and lower mounting ears 4 fixed at the front and back at the bottom. The lower mounting ears 4 are fixed to the required installation position by lower fixing bolts 7. The upper mounting ears 3 and lower mounting ears 4 are arranged opposite to each other, and the upper mounting ears 3 and lower mounting ears 4 are integral with the support base plate 1. The circuit board body 6 is fixed to the top of the upper mounting ears 3 by upper fixing bolts 5, and the circuit board body 6 is attached to the top of the support base plate 1.

[0025] refer to Figure 2-4 As shown, a fixed rod frame 9 is provided on both the left and right sides of the support base plate 1. The fixed rod frame 9 is fixed to the upper mounting ear 3 and the lower mounting ear 4 by a connecting plate 8. The connecting plate 8 and the fixed rod frame 9 are an integral structure, and the connecting plate 8 is fixed to the side of the upper mounting ear 3 and the lower mounting ear 4. Limiting grooves 10 are provided on both the upper and lower sides of the fixed rod frame 9. A reciprocating screw 11 is rotatably installed inside the limiting groove 10. A servo motor 12 is provided in front of the fixed rod frame 9 to drive the reciprocating screw 11. The output end of the servo motor 12 is connected to the reciprocating screw 11. A limiting slider 13 is slidably installed inside the limiting groove 10. The limiting slider 13 is threadedly connected to the reciprocating screw 11. The interior of block 13 has a threaded hole adapted to the reciprocating lead screw 11, and the reciprocating lead screw 11 is threaded into the threaded hole. The inner side of the fixed rod frame 9 has a movable seat 14, and the movable seat 14 is fixedly connected to the limit slider 13. The blower fan 15 is fixed inside the right movable seat 14, and the exhaust fan 16 is fixed inside the left movable seat 14.
