Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a shockproof embedded composite circuit board. Background Technology

[0002] A circuit board is a board used to mount corresponding electronic components and enable electrical conduction between them. Composite circuit boards are a type of circuit board. There are many types of composite circuit boards on the market, but most composite circuit boards do not support nesting operations and cannot be embedded inside a housing for protection. This can easily cause the electronic components on the composite circuit board to be directly exposed to the outside and damaged by collisions, affecting the normal use of the composite circuit board and causing certain losses and inconvenience to users.

[0003] A nested composite circuit board, as described in patent publication number CN215647572U, includes a circuit board body with a fixed base sleeve. The fixed base sleeve has a rectangular groove whose top communicates with the outside. The circuit board body is located within the rectangular groove and engages with it. Four positioning protrusions arranged in a matrix are provided on the bottom wall of the rectangular groove. The fixed base sleeve also includes a protective mechanism, comprising a protective top cover fitted onto the circuit board body. A rectangular plate is provided on the bottom cylindrical body of the protective top cover. The positioning protrusions pass through the circuit board body and the rectangular plate. Annular grooves are provided on the annular sides of the positioning protrusions. Limiting components are provided on the protective top cover. The fixed base sleeve enables nesting operations and facilitates fixing, installation, and disassembly, providing convenience for the user.

[0004] However, this circuit board has shortcomings in its use. Due to the lack of necessary shock absorption devices, the circuit board will become unstable when facing vibration-prone usage scenarios, which will have an adverse effect on the electronic components on the circuit board.

[0005] Based on this, a shock-resistant embedded composite circuit board is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figure 1 and Figure 2 As shown, the shockproof embedded composite circuit board includes a circuit board body 100. Each of the circuit board body 100 has a positioning hole 101 near its end. The bottom of the circuit board body 100 has a fixing component, which is used to fix the circuit board body 100. The bottom of the fixing component has four buffer components near its end. The top of the circuit board body 100 also has a protective component that cooperates with the fixing component to protect the composite circuit board from dust and prevent it from being directly exposed to impact.

[0026] In one embodiment, such as Figure 1 and Figure 3As shown, the fixing assembly includes a fixing plate 200, a heat dissipation mounting hole 201, a support sleeve 202, a threaded mounting hole 203, a damper sleeve 204, and a sliding mounting hole 205. The fixing plate 200 has a cuboid mounting groove at its top, providing space for the installation of the circuit board body 100. A through heat dissipation mounting hole 201 is located in the middle of the cuboid mounting groove to provide ventilation and heat dissipation for the bottom of the circuit board body 100. Four support sleeves 202 are located near the ends of the fixing plate 200 to support the placement of the circuit board body 100. Each support sleeve 202 has a threaded mounting hole 203 that penetrates the fixing plate 200. Multiple damper sleeves 204 are located at the bottom of the fixing plate 200, and each damper sleeve 204 has a sliding mounting hole 205 to provide a pre-set sliding track for the buffer assembly.

[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, the position of the threaded mounting hole 203 corresponds to the position of the positioning hole 101, and the damper sleeve 204 corresponds one-to-one with the threaded mounting hole 203, which facilitates the installation of the buffer assembly at the four corners of the fixed assembly.

[0028] In one embodiment, such as Figure 1 As shown, the protective component includes a protective cover 300. The protective cover 300 has four protective cover mounting holes 301 around its perimeter, corresponding to the positioning holes 101. An upper positioning nut 302 is fitted on the upper part of the protective cover mounting holes 301.

[0029] In one embodiment, such as Figure 4 As shown, the buffer assembly includes a damper housing 500, with a rubber strip 501 on each of the left and right sides of the damper housing 500 to buffer the downward or upward force from the outside. At the same time, the rubber strip 501 can effectively reduce noise during the sliding process. A damper cylinder 502 is opened inside the damper housing 500, and a limiting mounting hole 503 is provided at the bottom of the damper cylinder 502. A through mounting hole is provided at the top of the damper housing 500, and a piston rod 600 is fitted inside the mounting hole.

[0030] In one embodiment, such as Figure 3 and Figure 4As shown, the size of the rubber strip 501 and the sliding groove mounting hole 205 are matched with each other. A piston 700 is installed inside the damper cylinder 502. An oil hole 701 is provided on the top of the piston 700 near the left and right sides to facilitate the damping medium inside the damper cylinder 502 to pass through the piston 700 vertically. A limiting block 702 is provided at the middle of the bottom of the piston 700, which matches the limiting mounting hole 503. When the piston 700 moves to the bottom of the damper cylinder 502, it limits the piston 700.

[0031] In one embodiment, such as Figure 4 As shown, the damper cylinder 502 contains damping media located on the upper and lower sides of the piston 700.

[0032] In this embodiment, after fixing the position of the piston 700, when the buffer assembly is subjected to external pressure, the piston 700 moves relative to the damper cylinder 502, and the damping medium flows rapidly in the two separated cavities. The molecules of the medium and the medium and the piston generate intense friction. When the medium passes through the oil hole 701, it generates huge throttling damping. The resultant force of these actions is converted into heat and dissipated through the movement of the piston 700 in the viscous liquid, so that the movement speed of the piston 700 gradually decreases, thereby achieving the purpose of damping and energy dissipation.

[0033] In one embodiment, such as Figure 2 and Figure 4 As shown, the upper part of the piston rod 600 is provided with threads that mate with the threaded mounting hole 203 and the protective cover mounting hole 301, connecting the fixing component, the positioning plate and the protective component into a whole; a lower positioning nut 601 is sleeved on the upper part of the piston rod 600, and by rotating the lower positioning nut 601, the distance between the fixing plate 200 and the damper housing 500 can be adjusted, thus adapting to vibrations in different scenarios; the lower part of the piston rod 600 is connected to the upper end face of the piston 700, connecting the fixing component and the buffer component into a whole.

[0034] In one embodiment, such as Figure 4 As shown, a base plate 400 is also connected to the bottom of the damper housing 500. Each of the left and right ends of the base plate 400 is provided with a bolt fixing groove 401. The buffer assembly can be fixed by using bolts and washers passing through the bolt fixing grooves 401.

[0035] Working principle: Based on common vibration scenarios, the position of the lower positioning nut 601 is pre-adjusted, then the damper housing 500 is aligned and inserted into the damper sleeve 204, and the upper positioning nut 302 is tightened to complete the connection. Finally, the buffer assembly is fixed by the bolt fixing slot 401. When the circuit board is subjected to force, the fixing assembly and the piston rod 600 together compress the piston 700 relative to the damper cylinder 502. The damping medium flows rapidly in the two separated cavities. The molecules of the medium and the medium and the piston generate intense friction. When the medium passes through the oil hole 701, it generates huge throttling damping, which gradually reduces the movement speed of the piston 700. When the vibration ends, due to the internal and external pressure difference between the damper cylinder 502 and the air, the piston rod 600 drives the fixing assembly to slowly return to its original position.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
