[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a PCBA circuit board with a drop buffer function, comprising a protective shell 1, a damper 8 is fixedly connected to the bottom of the protective shell 1, a placement plate 9 is fixedly connected to the output end of the damper 8, one end of a buffer plate 10 is rotatably connected to both sides of the lower part of the placement plate 9, buffer rods 11 are fixedly connected to both sides of the inside of the protective shell 1, buffer blocks 13 are slidably connected to the outside of the two buffer rods 11, the other ends of the two buffer plates 10 are rotatably connected to the upper parts of the two buffer blocks 13, buffer springs 12 are sleeved on both sides of the outside of the two buffer rods 11, fixed components are provided on both sides of the upper part of the placement plate 9, connecting blocks 19 are fixedly connected to both sides of the outside of the placement plate 9, grooves 21 are opened on both sides of the inside of the protective shell 1, fixed rods 20 are fixedly connected to the inside of the two grooves 21, two connecting blocks 19 are slidably connected to the outside of the two fixed rods 20, and a PCBA circuit board body 7 is provided on the upper part of the placement plate 9.
[0025] By providing the protective shell 1, a protective effect is achieved on the PCBA circuit board body 7. When the PCBA circuit board body 7 falls from a height, the placement plate 9 will cause the damper 8 to shrink, and at the same time, the placement plate 9 moves to both sides with the two buffer plates 10 rotating on both sides of the lower part. When the two buffer plates 10 move to both sides, they move to both sides with the two buffer blocks 13 rotating and connected at the other ends outside the two buffer rods 11. When the two buffer blocks 13 move to both sides, the four buffer springs 12 are squeezed, and the four buffer springs 12 are deformed by the force to absorb the force generated by the fall. The PCBA circuit board is installed inside the protective shell 1 to protect it, and then the buffer springs 12 are squeezed and deformed to absorb the force generated by the fall, so that the PCBA circuit board is not prone to violent shaking or twisting when it falls, thereby improving the protective effect of the PCBA circuit board. The two connecting blocks 19 are slidably connected to the outside of the two fixed rods 20 to play a guiding role.
[0026] Reference Figure 2 and Figure 5 The fixing assembly includes an L-shaped plate 14, which is fixedly connected to both sides of the upper part of the placement plate 9. The L-shaped plate 14 is internally threaded with a screw rod 15, the top of the screw rod 15 is fixedly connected to a turntable 16, the bottom of the screw rod 15 is rotatably connected to a positioning plate 17, and a rubber pad 18 is installed at the bottom of the positioning plate 17.
[0027] By placing the PCBA circuit board body 7 on the upper part of the placement plate 9, and then rotating the turntable 16 to rotate the screw rod 15 fixed at the bottom, the screw rod 15 rotates to move the positioning plate 17 connected to the bottom rotation, and the positioning plate 17 moves to move the rubber pad 18 installed at the bottom, so that the rubber pad 18 is in contact with the surface of the PCBA circuit board body 7, the PCBA circuit board body 7 is easily fixed to avoid shaking.
[0028] Reference Figure 1 , Figure 2 and Figure 3 The protective shell 1 has mounting plates 2 fixedly connected to both sides of the outside, mounting holes 3 are provided on both sides of the inside of the two mounting plates 2, a cover plate 4 is installed on the top of the protective shell 1, a transparent observation window 5 is installed inside the cover plate 4, and a ventilation hole 6 is provided on the right side of the inside of the protective shell 1.
[0029] The installation of the protective shell 1 is facilitated by providing the mounting plate 2 and the mounting hole 3. The protective shell 1 is sealed by providing the cover plate 4 to prevent dust from entering. The transparent observation window 5 allows the user to directly view the operation of the PCBA circuit board body 7 inside the protective shell 1 without opening the cover plate 4. The ventilation holes 6 facilitate heat dissipation of the PCBA circuit board body 7.
[0030] Working principle: When the PCBA circuit board accidentally falls, the damper 8 will move with the placement plate 9, and the movement of the placement plate 9 will move the buffer plates 10 connected to the lower sides with rotation to both sides. When the two buffer plates 10 move to both sides, they will move the two buffer blocks 13 connected to the other ends with rotation to both sides outside the two buffer rods 11. The two buffer blocks 13 move to both sides to squeeze the buffer springs 12 set on both sides of the outside of the two buffer rods 11. The multiple buffer springs 12 are squeezed and deformed to absorb the force generated by the fall, so that the PCBA circuit board is installed inside the protective shell 1 to protect it, and then the multiple buffer springs 12 are squeezed and deformed to absorb the force generated by the fall, so that the PCBA circuit board is not easy to shake or twist violently when it falls, thereby improving the protection effect of the PCBA circuit board.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
