Technical Field

[0001] This utility model relates to the field of electronic engineering, and in particular to a vehicle control circuit board assembly. Background Technology

[0002] In automotive electronic systems, the vehicle control circuit board assembly is a core component that needs to operate stably while the vehicle is in motion. Its operating environment faces challenges such as continuous vibration and heat buildup caused by the high-frequency operation of the circuit board, which places high demands on the reliability and heat dissipation performance of the circuit components.

[0003] Currently, traditional vehicle infotainment system circuit board assemblies mostly employ rigid mounting methods, using simple brackets to fix the circuit board body, lacking effective vibration damping structures. When a vehicle is in motion, vibrations from road bumps are directly transmitted to the circuit board, easily leading to loose circuit components, solder joint detachment, or even wire breakage, affecting the component's lifespan.

[0004] Therefore, a vehicle control circuit board assembly is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vehicle control circuit board assembly, which aims to improve the problem that the circuit board assembly is usually installed in a rigid manner without an effective buffer structure, making the circuit board more susceptible to damage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vehicle infotainment control circuit board assembly includes a mounting bracket and a frame. Two dampers are fixedly connected to the front and rear sides of the mounting bracket. Springs are sleeved on the outside of the dampers. A cavity is opened inside the frame. A circuit board body is disposed inside the cavity. A heat dissipation component for dissipating heat from the circuit board body is disposed inside the cavity.

[0008] As a further description of the above technical solution:

[0009] The heat dissipation assembly includes a heat sink and multiple heat dissipation fins. The heat sink is disposed outside the cavity. The front side of the circuit board body is detachably connected to the outside of the heat sink. The outside of the multiple heat dissipation fins is fixedly connected to the other side of the heat sink.

[0010] As a further description of the above technical solution:

[0011] The mounting bracket has multiple cable insertion holes on its right side. Multiple fixing plates are fixedly connected to the right side of the mounting bracket. A fixing shaft is fixedly connected to the right side of the fixing plate. A dustproof shell is rotatably connected to the outside of the fixing shaft. A torsion spring is provided on the side of the dustproof shell that is close to the mounting bracket.

[0012] As a further description of the above technical solution:

[0013] The other side of the damper is fixedly connected to the outside of the frame, and the front side of the circuit board body is slidably connected to the inside of the cavity;

[0014] As a further description of the above technical solution:

[0015] One end of the spring is fixedly connected to the outside of the mounting bracket, and the other end of the spring is fixedly connected to the outside of the frame.

[0016] As a further description of the above technical solution:

[0017] The heat sink is made of silicone material, and the heat sink fins are made of copper sheet material;

[0018] As a further description of the above technical solution:

[0019] The dust cover is positioned above the connector hole;

[0020] As a further description of the above technical solution:

[0021] The dampers are symmetrically distributed on the outside of the mounting frame.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the vibration generated by the vehicle's movement is buffered by symmetrically distributed dampers and springs, and the heat dissipation plate made of silicone material drives the copper heat dissipation fins to quickly conduct and dissipate the heat of the circuit board.

With the help of the torsion spring, the potential energy is released to drive the dust cover to automatically reset and cover the plug hole.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a vehicle control circuit board assembly, comprising a mounting frame 1 that serves as the overall support structure for the vehicle control circuit board assembly, provides a mounting base for components such as dampers 3 and springs 4, and ensures the stable connection and layout of each component, and a frame 2 with an internal cavity 5 to accommodate the circuit board body 8. The frame 2 is connected to the dampers 3 and springs 4 and forms an elastic support structure under the support of the mounting frame 1 to ensure the installation stability of the circuit board body 8. Two dampers 3 are symmetrically fixed to the front and rear sides of the mounting frame 1, and absorb and consume the vibration energy transmitted to the mounting frame 1 during vehicle operation by utilizing their own damping characteristics to reduce the vibration amplitude of the frame 2 and the circuit board body 8.

[0034] The other side of the damper 3 is fixedly connected to the outside of the frame 2. The dampers 3 are symmetrically distributed outside the mounting bracket 1. A spring 4 is fitted outside the damper 3, which is connected to the mounting bracket 1 and the frame 2 at both ends. It undergoes elastic deformation when the vehicle vibrates to further buffer the vibration impact and cooperate with the damper 3 to evenly distribute the vibration force. One end of the spring 4 is fixedly connected to the outside of the mounting bracket 1, and the other end of the spring 4 is fixedly connected to the outside of the frame 2. The inside of the frame 2 is a cavity 5, which provides installation space for the circuit board body 8 and ensures that the circuit board body 8 is stably set in the frame 2. It also provides an installation position for the heat dissipation component. The inside of the cavity 5 is a circuit board body 8, which is the core component of the vehicle control system. It is set inside the cavity 5, carries the circuit components and realizes the control function, and is slidably connected to the front of the cavity 5 for easy installation and removal. The front of the circuit board body 8 is slidably connected to the inside of the cavity 5. The inside of the cavity 5 is a heat dissipation component for heat dissipating the circuit board body 8.

[0035] The heat dissipation assembly includes a heat sink 6 and multiple heat dissipation fins 7. The heat sink 6 is made of silicone material, is located inside the cavity 5, and is closely attached to the rear side of the circuit board body 8. The heat sink 7 is made of copper sheet material, is fixedly connected to the other side of the heat sink 6, is distributed in an array, greatly increases the contact area with the air, and accelerates the dissipation of heat to the surrounding air to improve heat dissipation efficiency. The exterior of the heat sink 6 is located inside the cavity 5, the front side of the circuit board body 8 is detachably connected to the exterior of the heat sink 6, and the exterior of the multiple heat dissipation fins 7 is fixedly connected to the other side of the heat sink 6.

[0036] Reference Figure 1 , Figure 4 and Figure 5The right side of the mounting bracket 1 has multiple cable entry holes 9 for connecting external cables to enable electrical signal or power transmission between the circuit board body 8 and external devices. Multiple fixing plates 10 are fixedly connected to the right side of the mounting bracket 1 to provide mounting support for the fixing shaft 11, ensuring its stable placement on the mounting bracket 1. A dust cover 12 is fixedly connected to the right side of the fixing plate 10 and rotatably connected to it, providing a support shaft for the rotation of the dust cover 12 so that it can rotate around the fixing shaft 11. A fixed shaft 11 is rotatably connected to the outside of the fixed shaft 11, above the wire insertion hole 9. When not connected, the dust cover 12 covers the wire insertion hole 9 under the action of the torsion spring 13 to prevent dust and debris from entering and keep the interface clean. The dust cover 12 is located above the wire insertion hole 9. On the side of the dust cover 12 close to the mounting bracket 1, there is a torsion spring 13. When the dust cover 12 rotates, it is compressed and accumulates elastic potential energy. When released, it drives the dust cover 12 to automatically reset to maintain the state of the dust cover 12 covering the wire insertion hole 9.

[0037] Working Principle: When the vehicle control circuit board assembly is put into use, the circuit board body 8 is installed in the cavity 5 inside the frame 2. In the initial state, the mounting bracket 1 serves as the overall support structure. The dampers 3, which are symmetrically fixed on the front and rear sides inside, and the springs 4, which are sleeved on the outside, are in a naturally relaxed state, providing elastic support for the frame 2. The heat dissipation component works simultaneously: the silicone heat sink 6 is tightly attached to the rear side of the circuit board body 8. With the good thermal conductivity of silicone, the heat generated by the circuit board during operation is quickly conducted to the copper heat dissipation fins 7 on the other side of the heat sink 6. Multiple heat dissipation fins 7 are distributed in an array, which greatly increases the contact area with the air, accelerates the dissipation of heat to the surrounding air, and continuously maintains the temperature stability of the circuit board body 8, avoiding the degradation of circuit performance or damage to components due to overheating.

[0038] During vehicle operation, vibrations generated by the vehicle's movement are transmitted to dampers 3 and springs 4 via mounting bracket 1. Dampers 3 utilize their damping characteristics to absorb and dissipate vibration energy, reducing the vibration amplitude; springs 4 simultaneously undergo elastic deformation, further buffering the vibration impact. Because dampers 3 are symmetrically distributed outside mounting bracket 1, they can evenly disperse vibration forces. The combined effect of both effectively reduces the vibration of frame 2 and the internal circuit board body 8, protecting circuit components from vibration damage and improving the stability and lifespan of the components.

[0039] When connecting external cables to the circuit board body 8, the operator manually operates the dust cover 12: the dust cover 12 rotates around the fixed shaft 11 on the fixed plate 10, compressing the torsion spring 13 during rotation, causing the torsion spring 13 to accumulate elastic potential energy. After the dust cover 12 flips to fully expose the plug hole 9, the external cable is inserted into the plug hole 9. After the wiring is completed, the dust cover 12 is released, the torsion spring 13 releases the accumulated elastic potential energy, causing the dust cover 12 to automatically reset and cover the plug hole 9 again, preventing dust and debris from entering the plug hole 9, keeping the interface clean, and avoiding problems such as poor contact and short circuits caused by dust accumulation. When not wiring, the dust cover 12, under the continuous force of the torsion spring 13, always covers the plug hole 9, maintaining a good dustproof effect.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
