[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board component protection structure. Background Technology

[0002] A circuit board, also known as a printed circuit board, is an indispensable component of electronic devices. It provides a fixed structure to support and connect various electronic components, such as resistors, capacitors, and transistors, so that these components can work together according to their designed functions.

[0003] The authorized announcement number describes a single-sided electrical component circuit board, including a protective housing. Inside the protective housing, pads are fixedly connected to the front and rear ends of both sides of the bottom. A circuit board body is mounted on the upper end of the four pads, and components are fixedly installed on the upper surface of the circuit board body. Spring plates are provided on both sides inside the protective housing. This patent proposes a design using a protective housing, top cover, dustproof net, support, and shock-absorbing pads to install the circuit board body inside the protective housing. The shock-absorbing pads can effectively absorb external impacts and vibrations, achieving the purpose of protecting the circuit board. However, during use, the shock-absorbing pads are located at the bottom of the circuit board. When impacted from the bottom, they cannot absorb the impact and vibration from below, thus failing to provide comprehensive protection for the circuit board components.

[0004] Therefore, it is necessary to design a circuit board component protection structure that can provide comprehensive protection. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents where the shock-absorbing pads are located at the bottom of the circuit board and cannot absorb the impact and vibration from the bottom, thus failing to provide comprehensive protection for the circuit board components, this utility model provides a circuit board component protection structure that can provide comprehensive protection.

[0006] The technical solution is as follows: A circuit board component protection structure includes a lower housing, an upper housing, fixing blocks, and fixing screws. The upper housing is mounted on the lower housing. A wiring groove is opened on the right side of the upper housing. Multiple fixing blocks are fixedly connected to the exterior of both the lower and upper housings. Two corresponding fixing blocks on the lower and upper housings are fixed by fixing screws. The structure also includes a mounting plate, a damper, a connecting plate, a placement seat, a circuit board body, a terminal block, a slip ring, a push rod, and a first elastic element. A set of mounting plates is installed on each side of the interior of the lower housing. A damper is mounted on the mounting plate, and a connecting plate is mounted on the damper. A placement seat is mounted on each set of connecting plates. A circuit board body is positioned between two placement seats. A terminal block is mounted on one side of the circuit board body. Sliding grooves are opened on both sides of the placement seat. A slip ring is slidably mounted in the sliding groove. A push rod is fixedly connected to the slip ring. One end of the push rod located outside the sliding groove contacts the circuit board body. A first elastic element connects the sliding groove and the push rod.

[0007] As a further preferred embodiment, it also includes an exhaust fan, a perforated plate, a placement frame, and a dehumidifier. Multiple exhaust fans are embedded between the lower and upper housings. Multiple ventilation slots are provided on the side of the lower and upper housings away from the exhaust fans. A perforated plate is installed inside the lower housing. A placement frame is slidably arranged inside the perforated plate. The placement frame penetrates the upper housing and a dehumidifier is placed inside the placement frame.

[0008] As a further preferred embodiment, it also includes a lower fixed seat, guide rods, an upper fixed seat, and a second elastic element. The lower fixed seat is installed at the lower part of the wiring groove of the upper housing. Two guide rods are fixedly connected to the inner side of the upper housing. The upper fixed seat is slidably arranged between the two guide rods. Limiting grooves are opened on both the upper fixed seat and the lower fixed seat. Two second elastic elements are connected between the upper fixed seat and the upper housing.

[0009] As a further preferred option, an observation board is also included, which is embedded in the upper housing.

[0010] As a further preferred option, a rubber block is also included, with the end of the push rod near the circuit board body having the rubber block fixed to it.

[0011] As a further preferred option, a protective net is also included, with the exhaust fan having a protective net installed on one side outside the lower housing.

[0012] This utility model has the following advantages: 1. The lower and upper housings protect and dustproof the electronic components on the circuit board body. The damper reduces shock to the circuit board body from the vertical direction. The circuit board body is buffered under the action of the first elastic element, the top rod and the slip ring, thereby achieving the purpose of comprehensive protection of the circuit board body and avoiding damage to the circuit board body from all directions during use, thus extending the service life of the circuit board components.

[0013] 2. By starting the exhaust fan, outside air is drawn in. The air is dehumidified by the dehumidifier and kept dry. The air carries away the heat generated by the circuit board during operation, thereby achieving the purpose of heat dissipation for the circuit board and preventing the electronic components on the circuit board from being damaged due to overheating.

[0014] 3. Under the action of the second elastic element, the limiting grooves on the upper and lower fixed seats cooperate to fix the wires, thereby preventing the wires from falling off the terminals during use and improving the stability of the circuit board body during use.

Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0026] Example 1: A circuit board component protection structure, see reference. Figures 1-4As shown, the device includes a lower housing 1, an upper housing 2, fixing blocks 3, and fixing screws 4. The upper housing 2 is mounted on the lower housing 1. A wiring groove is opened on the right side of the upper housing 2. Four fixing blocks 3 are fixedly connected to the lower housing 1 and the upper housing 2 externally by welding. The two fixing blocks 3 on the lower housing 1 and the upper housing 2 respectively are fixed by fixing screws 4. The device also includes a mounting plate 5, a damper 6, a connecting plate 7, a placement seat 8, a circuit board body 9, a terminal block 901, a slip ring 10, a push rod 11, and a first elastic element 13. A set of mounting plates 5 is installed on each of the front and rear sides inside the lower housing 1. Each set of mounting plates 5 contains two mounting plates. A damper 6 is installed on the mounting plate 5, and a connecting plate 7 is installed on the damper 6. A placement seat 8 is installed on each set of connecting plates 7 by bolt connection. A circuit board body 9 is provided in the middle, and an observation plate 23 is embedded in the upper housing 2. The usage of the circuit board body 9 inside the upper housing 2 can be observed through the observation plate 23. A terminal block 901 is installed on the top right side of the circuit board body 9. Slide grooves 12 are provided on both sides of the placement seat 8. A slip ring 10 is slidably provided in the slide groove 12. A push rod 11 is fixed to the slip ring 10 by welding. One end of the push rod 11 outside the slide groove 12 is in contact with the circuit board body 9. A rubber block 24 is fixed to the end of the push rod 11 near the circuit board body 9. When the push rod 11 abuts against the circuit board body 9, the rubber block 24 contacts the circuit board body 9, which can buffer and protect the circuit board body 9. A first elastic element 13 is connected between the slide groove 12 and the push rod 11. The first elastic element 13 is sleeved on the push rod 11.

[0027] When it is necessary to fix the circuit board body 9, slide the push rod 11 outward. The push rod 11 drives the slip ring 10 to slide outward. At the same time, the push rod 11 compresses the first elastic element 13, causing it to deform. Then, place the circuit board body 9 between the two placement seats 8. Then, release the push rod 11. The first elastic element 13 returns to its original shape, causing the push rod 11 and slip ring 10 to slide inward, so that the push rod 11 abuts against the circuit board body 9. Then, cover the lower housing 2 on the lower housing 1. Fix the lower housing 1 and the fixing block 3 on the upper housing 2 with fixing screws 4. The lower housing 1 and the upper housing 2 protect the electronic components on the circuit board body 9 from dust. When subjected to vertical impact during use, the lower housing 1 and the upper housing 2 will... The housing 2 moves up and down, causing the circuit board body 9 to sway up and down due to inertia. The damper 6 dampens the circuit board body 9 from the vertical direction, preventing damage to the circuit board body 9 due to vertical impact. During use, when it is impacted from the left and right sides, the lower housing 1 and the upper housing 2 move left and right, causing the circuit board body 9 to sway left and right due to inertia. The circuit board body 9 presses the push rod 11 to slide outward. The push rod 11 drives the slip ring 10 to slide outward. At the same time, the push rod 11 presses the first elastic element 13 to deform. Thus, under the action of the first elastic element 13, the push rod 11 and the slip ring 10, the circuit board body is buffered, thereby preventing damage to the circuit board body 9 due to left and right impact.

[0028] Example 2: Based on Example 1, refer to Figure 1 , Figure 5 and Figure 6 As shown, it also includes an exhaust fan 14, a perforated plate 16, a placement frame 17, and a dehumidifier 18. Three exhaust fans 14 are installed between the lower housing 1 and the upper housing 2 by means of bolts. Multiple ventilation slots 15 are opened on the right side of both the lower housing 1 and the upper housing 2 away from the exhaust fans 14. A perforated plate 16 is installed on the left side inside the lower housing 1 by means of bolts. A placement frame 17 is slidably arranged in the perforated plate 16. The placement frame 17 penetrates the upper housing 2 and the dehumidifier 18 is placed in the placement frame 17.

[0029] During the operation of the circuit board body 9, the exhaust fan 14 is activated to draw in external air. The drawn-in air enters the placement frame 17 through the perforated plate 16 and is then dehumidified by the desiccant 18, keeping the air entering the cavity between the lower housing 1 and the upper housing 2 dry. The air carries away the heat generated by the circuit board body 9 during operation and is then discharged through the ventilation groove 15, thereby achieving the purpose of heat dissipation for the circuit board body 9 and preventing the electronic components on the circuit board body 9 from being damaged due to overheating.

[0030] See Figures 7-9As shown, it also includes a lower fixed seat 19, a guide rod 20, an upper fixed seat 21, and a second elastic element 22. The lower fixed seat 19 is installed at the lower part of the wiring groove of the upper housing 2 by bolt connection. Two guide rods 20 are fixedly connected to the inner side of the upper housing 2. The upper fixed seat 21 is slidably arranged between the two guide rods 20. Limiting grooves are opened on both the upper fixed seat 21 and the lower fixed seat 19. Two second elastic elements 22 are connected between the upper fixed seat 21 and the upper housing 2. The second elastic elements 22 are sleeved on the guide rods 20. A protective net 25 is installed on the side of the exhaust fan 14 located outside the lower housing 1. The protective net 25 can isolate foreign objects from the exhaust fan 14 and prevent foreign objects from being rolled into the lower housing 1.

[0031] When connecting the circuit board body 9 to the wiring, push the upper fixing seat 21 upward. The upper fixing seat 21 slides upward and squeezes the second elastic member 22 to deform. Then, pass the wire through the gap between the upper fixing seat 21 and the lower fixing seat 19 and insert it into the terminal 901. Then release the upper fixing seat 21. The second elastic member 22 returns to its original shape and drives the upper fixing seat 21 to move downward. The upper fixing seat 21 and the limiting groove on the lower fixing seat 19 cooperate to fix the wire, thereby preventing the wire from falling off the terminal 901 during use and improving the stability of the circuit board body 9 during use.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
