Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board with uniform heat dissipation. Background Technology

[0002] As the core electrical connection and component support carrier in electronic equipment, the design of circuit boards must take into account both structural stability and signal transmission efficiency. At the same time, heat dissipation performance is a key factor in ensuring the reliable operation of the equipment.

[0003] Patent specification CN222884842U discloses a circuit board with a heat sink, including a circuit board body. A connecting frame is provided below the circuit board body. The inner wall of the connecting frame has four first fixing slots. A first connecting rod is slidably connected to the inner wall of each first fixing slot. Two connecting plates are provided on the outer side of the connecting frame. Two hook plates are fixedly connected to the outer surface of each connecting plate. A pre-tension spring is sleeved on the outer surface of each first connecting rod. By pulling the hook plate, the hook plate drives the corresponding connecting plate to move horizontally in opposite directions. At this time, the connecting plate will drive the corresponding first connecting rod to slide horizontally in the corresponding first fixing slot, and the corresponding pre-tension spring will start to compress, so that the hook plate has a horizontal force towards the connecting frame. Thus, the device can quickly install circuit boards of different sizes and connecting frames by adjusting the position of the hook plates.

[0004] However, in implementing the relevant technology, the above-mentioned circuit board with heat sink has the following problems: the preload spring is compressed to create a horizontal force on the hook plate towards the connecting frame, thereby achieving the effect of quickly installing circuit boards of different sizes and connecting frames by adjusting the position of the hook plate. However, the force applied by the clamping structure is different when clamping larger and smaller circuit boards, which may cause damage to the larger circuit board. When clamping smaller circuit boards, the clamping force may be too small, resulting in the circuit board falling off. In view of this, a circuit board with uniform heat dissipation is provided to overcome the above defects. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a circuit board with uniform heat dissipation, comprising a housing, an adjusting base fixedly connected inside the housing, a guide post slidably connected inside the adjusting base, a pre-tension spring fixedly connected to the outer side of the guide post, a clamping plate fixedly connected to the end of the pre-tension spring away from the guide post, a linkage rod provided inside the pre-tension spring, a fourth spring fixedly connected inside the linkage rod, a positioning bead fixedly connected to the end of the fourth spring away from the linkage rod, an anti-slip gripper fixedly connected to the upper end of the clamping plate, a base plate fixedly connected inside the housing, a second spring fixedly connected to the outer side of the base plate, a button structure fixedly connected to the end of the second spring away from the base plate, a support rod provided inside the second spring, a push block fixedly connected to the inner side of the support rod, a hollow plate fixedly connected inside the housing, a circuit board body provided at the upper end of the hollow plate, a micro motor fixedly connected inside the hollow plate, and a micro fan fixedly connected to the output end of the micro motor.

[0007] As a further description of the above technical solution: the inner side of the anti-slip gripper is in contact with the outer side of the circuit board body, and the inner side of the push block is engaged with the inside of the adjustment base, so that under the action of the clamping plate, the anti-slip gripper at the upper end of the clamping plate can clamp the outer side of the circuit board body on the inner side.

[0008] As a further description of the above technical solution: the linkage rod has a cavity inside, the second spring and the positioning ball are inside the cavity, and a circular groove is provided on the outside of the cavity. The shape and size of the cross-section of the circular groove match the shape and size of the cross-section of the positioning ball, so that the positioning ball can engage with the adjustment base under the push of the second spring.

[0009] As a further description of the above technical solution: a protrusion is provided on the inner side of the push block, and a circular hole is provided on the outer side of the adjustment base, and the diameter of the circular hole matches the diameter of the protrusion, so that the protrusion on the inner side of the push block can push the positioning ball through the adjustment base.

[0010] As a further description of the above technical solution: guide grooves are provided at both the front and rear ends of the base plate, and the diameter of the guide grooves matches the diameter of the support rod, so that the support rod can slide inside the base plate.

[0011] As a further description of the above technical solution: a quick-release slide rail is fixedly connected to the outer side of the hollow plate, a sliding latch is fixedly connected to the lower end of the outer shell, an elastic buckle is rotatably connected to the lower end of the sliding latch, and a tension spring is fixedly connected to the inner side of the elastic buckle, so that the outer shell can engage with the hollow plate.

[0012] As a further description of the above technical solution: the quick-release slide rail has square grooves at both the upper and lower ends, and the shape and size of the cross-section of the square grooves are matched with the shape and size of the cross-section of the sliding lock tongue, so that the elastic latch can engage with the quick-release slide rail under the push of the tension spring.

[0013] This utility model has the following beneficial effects:

[0014] The circuit board with heat sink designed in this utility model achieves pre-mechanical adjustment of the initial position of the clamping structure by adjusting the design and cooperation of the base and guide post, and sets the initial spacing of the clamping plates to adapt to circuit boards of different sizes. After the size adaptation is completed, the clamping force is applied by using the spring tension clamping structure to provide a relatively stable and suitable clamping force for circuit boards of different specifications, taking into account both clamping reliability and protection.

[0015] The circuit board with heat sink designed in this utility model uses a sliding latch and quick-release slide rail design. By pressing the elastic latch and pushing the outer shell upward, the outer shell and the hollow board can be separated, thus separating the clamping structure from the heat dissipation structure. This reduces maintenance complexity and time costs, while also facilitating device repair and module replacement by staff. Attached Figure Description

[0026] As a further implementation of the above technical solution: the inner side of the anti-slip gripper 9 is attached to the outer side of the circuit board body 15, and the inner side of the push block 14 is engaged with the inside of the adjustment base 2, so that under the action of the clamping plate 8, the anti-slip gripper 9 at the upper end of the clamping plate 8 can clamp the outer side of the circuit board body 15 on the inner side.

[0027] As a further implementation of the above technical solution: the linkage rod 5 has a cavity inside, the fourth spring 6 and the positioning bead 7 are inside the cavity, and a circular groove is provided on the outside of the cavity. The shape and size of the cross-section of the circular groove match the shape and size of the cross-section of the positioning bead 7, so that the positioning bead 7 can engage with the adjusting base 2 under the push of the fourth spring 6.

[0028] As a further implementation of the above technical solution: a protrusion is provided on the inner side of the push block 14, and a circular hole is provided on the outer side of the adjusting base 2, and the diameter of the circular hole matches the diameter of the protrusion, so that the protrusion on the inner side of the push block 14 can push the positioning bead 7 through the adjusting base 2.

[0029] As a further implementation of the above technical solution: guide grooves are provided at both ends of the base plate 10, and the diameter of the guide grooves matches the diameter of the support rod 13, so that the support rod 13 can slide inside the base plate 10.

[0032] Working principle:

[0033] When using this utility model, pressing the button structure 12 causes the button structure 12 and the base plate 10 to compress the second spring 11, causing the button structure 12 to push the support rod 13 to move. The support rod 13 drives the push block 14 to move, causing the protrusion on the inner side of the push block 14 to contact the positioning bead 7 inside the adjusting base 2. Then, the push block 14 pushes the positioning bead 7 to move, causing the positioning bead 7 to disengage from the adjusting base 2 and compress the fourth spring 6. Then, the pre-position of the clamping plate 8 is adjusted according to the size of the circuit board to be clamped. Finally, the circuit board is placed on the upper end of the hollow plate 16. Pulling the clamping plate 8 on the outside of the outer shell 1 causes the linkage rod 5 to slide inside the guide post 3. Under the pull of the pre-tension spring 4, the anti-slip claw 9 clamps the circuit board body 15 on the inside. The micro motor 17 is started, and the output end of the micro motor 17 drives the micro fan 18 to rotate, which cools the circuit board at the top. When disassembling the hollow board 16, the elastic latch 21 on the outside of the sliding latch 20 is pressed, which causes the elastic latch 21 to press the tension spring 22 inward, thereby pushing the outer shell 1 upward, separating the sliding latch 20 from the quick-release slide rail 19, and separating the outer shell 1 from the hollow board 16.
