[0024] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0025] See also Figure 1-Figure 5In this embodiment, a sensor circuit board with high efficiency in heat dissipation includes a frame 1 and a circuit board body 2 installed in the frame 1. Support bars 113 for supporting the circuit board body 2 are provided on two opposite inner side surfaces of the frame 1 and located in the middle. A plurality of ventilation grooves are provided on the two opposite inner side surfaces of the frame 1 along the length direction thereof. Fixing components for fixing the circuit board body 2 to the support bars 113 are provided on the two side walls of the frame 1 where the support bars 113 are not provided.

[0026] In this embodiment, the frame 1, the circuit board body 2, the support bar 113, the ventilation slot and the fixing assembly are arranged so that the circuit board body 2 is overlapped on the support bar 113 and fixed by the fixing assembly, thereby preferably realizing the installation of the circuit board body 2 in the frame 1; wherein, since the support bar 113 is arranged at the middle position in the frame, when the frame 1 is installed on the bottom plate on which the circuit board is installed, there is a large gap between the circuit board body 2 and the bottom plate, thereby facilitating the flow of air, thereby facilitating the heat dissipation at the lower plate portion of the circuit board body 2 when the circuit board body 2 is installed on the bottom plate;

[0027] Among them, the provision of ventilation grooves can promote the flow of air inside and outside the frame when the frame 1 is installed on the base plate on which the circuit board is installed. The larger gap between the circuit board body 2 and the base plate can improve the heat dissipation effect of the sensor circuit board.

[0028] In this embodiment, placement grooves 3 are relatively arranged on the two side walls of the frame 1 where the support strips 113 are not provided, and fixing grooves 4 connected to the placement grooves 3 are opened on the sides of the placement grooves 3, and extension plates 5 extending into the corresponding placement grooves 3 are arranged on both sides of the circuit board body 2; the fixing component includes a box body 100 arranged on the outer side surface of the frame body 1, and a U-shaped plate 6 is arranged in the box body 100, which can extend into the placement grooves 3 through the fixing grooves 4 to clamp and fix the extension plate 5, and a telescopic component for controlling the U-shaped plate 6 to clamp and fix the extension plate 5 is arranged in the box body 100.

[0029] In actual use of this embodiment, when the circuit board body 2 is overlapped on the support bar 113, the extension plate 5 extends into the corresponding placement groove 3, wherein the U-shaped plate 6 can extend into the placement groove 3 through the fixing groove 4, and the extension plate 5 is clamped and fixed, thereby fixing the circuit board body 2, and preferably realizing the disassembly and assembly of the circuit board body 2 in the frame 1;

[0030] Among them, through the setting of the telescopic component, it is possible to push the U-shaped plate 6 in the box body 100 to be inserted into the placement groove 3 to clamp the extension plate 5. When the extension plate 5 needs to be released from the clamping, the U-shaped plate 6 can be retracted through the telescopic component to extend it from the placement groove 3, thereby releasing the clamping of the extension plate 5, and then the circuit board body 2 can be directly taken out of the frame 1, so that the circuit board body 2 can be disassembled and assembled on the frame 1 more conveniently.

[0031] In this embodiment, when the sensor circuit board with high efficiency in heat dissipation needs to be installed on a base plate, threaded holes can be opened on the frame 1 and installed between the frame and the base plate by screws, or the frame 1 can be used as a connector to complete the installation between the frame and the base plate according to actual usage.

The upper ventilation slot 7 is used for ventilation of the front side of the circuit board body 2, and the lower ventilation slot 8 is used for ventilation of the back side of the circuit board body 2.

[0033] In this embodiment, by setting the upper ventilation slots 7 and the lower ventilation slots 8, the air outside the frame 1 can be convected through the upper ventilation slots 7 arranged opposite to each other on both sides, thereby dissipating the heat on the front side of the circuit board body 2, and the air outside the frame 1 is convected through the lower ventilation slots 8 arranged opposite to each other on both sides, thereby dissipating the heat on the back side of the circuit board body 2, thereby better realizing the heat dissipation of the circuit board body 2 and improving the stability of the equipment operation.

[0034] See also Figure 1-Figure 5 In this embodiment, a cavity 101 with openings at both ends is provided in the box body 100, one end opening of the cavity 101 is connected to the fixing groove 4, and the other end opening is provided with a cover body 102; the telescopic component includes a short cylinder 103 arranged on the U-shaped plate 6, the short cylinder 103 is provided with an installation cavity, the installation cavity is provided with a rotating ring 104, the rotating ring 104 is provided with a sliding rod 105 extending out of the cover body 102, and the sliding rod 105 is used to drive the U-shaped plate 6 to extend into the placement groove 3 or extend out of the placement groove 3.

[0036] See also Figure 1-Figure 5 In this embodiment, a retaining ring 106 is provided in the cavity 101 and is sleeved on the sliding rod 105. The outer surface of the retaining ring 106 is symmetrically provided with connecting blocks 107 connected to the inner wall of the cavity 101. The sliding rod 105 located between the retaining ring 106 and the short cylinder 103 is sleeved with a spring 108 for pushing the U-shaped plate 6 into the placement groove 3 to clamp and fix the extension plate 5.

[0037] In this embodiment, through the setting of the retaining ring 106, the connecting block 107 and the spring 108, one end of the connecting block 107 is fixedly connected to the retaining ring 106, and the other end is fixedly connected to the inner wall of the cavity 101, so that the spring 108 can push the short cylinder 103 to drive the U-shaped plate 6 connected to the short cylinder 103 to extend into the placement groove 3, thereby clamping and fixing the extension plate 5.

[0038] See also Figure 1-Figure 5 In this embodiment, pull rods 109 are symmetrically provided at the end of the slide bar 105 extending out of the cover body 102. The pull rods 109 are used to pull the slide bar 105 to drive the U-shaped plate 6 to extend out of the placement slot 3 to release the clamping and fixation of the extension plate 5. Limiting plates 110 are symmetrically provided on both sides of the slide bar 105 in the cavity 101. Limiting slots 111 are symmetrically provided on the limiting plates 110. Blocks 112 that can pass through the limiting plates 110 and be inserted into the limiting slots 111 to limit the slide bar 105 are symmetrically provided on the slide bar 105.

[0039] In this embodiment, the pull rod 109 is fixedly connected to the slide bar 105 by setting the pull rod 109, the limit plate 110, the limit groove 111 and the block 112, so that the slide bar 105 can be pulled from the outside; the limit plate 110 is fixedly connected to the inner wall of the cavity 101 and is located on both sides of the slide bar 105, and the block 112 is fixedly connected to the slide bar 105. When it is necessary to release the spring 108 to push the U-shaped plate 6 to clamp the extension plate 5, the pull rod 109 can be pulled to drive the short cylinder 103 to compress the spring 108, so that the U-shaped plate 6 extends out of the placement groove 3. When the block 112 moves with the slide bar 10 5 is pulled out, and when it is displaced to a length that can be inserted into the limiting groove 111, the pull rod 109 is rotated to drive the slide bar 105 to rotate. When the slide bar 105 drives the block 112 to rotate until the block 112 and the limiting groove 111 can overlap, the pull rod 109 is released, and the spring 108 pushes the slide bar 105 to slide, so that the block 112 is inserted into the limiting groove 111. When the block 112 is inserted into the limiting groove 111, the U-shaped plate 6 is located outside the placement groove 3, thereby releasing its clamping and fixing of the extension plate 5, and preferably releasing the clamping and fixing of the circuit board body 2, so that when the circuit board body 2 needs to be repaired, the circuit board body 2 can be removed.

[0040] In this embodiment, the cover 102 may be made of a transparent material, so that the block 112 can be observed to be inserted into the limiting groove 111 when the block 112 rotates.

[0041] Working principle: When the sensor circuit board with high efficiency in heat dissipation is in use, the circuit board body 2 is overlapped on the support bar 113 and fixed by the clamping of the U-shaped plate 6 to realize its installation in the frame 1. When the circuit board body 2 needs to be removed for maintenance, the pull rod 109 can be pulled to drive the short cylinder 103 to compress the spring 108 to make the U-shaped plate 6 extend out of the placement groove 3. When the block 112 is pulled out and displaced with the slide bar 105 to a length that can be inserted into the limiting groove 111, the pull rod 109 is rotated to drive the slide bar 105 to rotate. When the slide bar 105 drives the block 112 to rotate until the block 112 and the limiting groove 111 can overlap, the pull rod 109 is released, and the spring 108 pushes the slide bar 105 to slide, so that the block 112 is inserted into the limiting groove 111, thereby releasing its clamping and fixing of the extension plate 5, and preferably releasing the clamping and fixing of the circuit board body 2, so that when the circuit board body 2 needs to be repaired, the circuit board body 2 can be removed.
