Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted camera circuit boards, and more particularly to a novel waterproof vehicle-mounted camera circuit board. Background Technology

[0002] With the continuous development of modern automotive technology, the application of in-vehicle cameras is becoming more and more widespread and crucial. They can not only provide reliable video evidence for the analysis and judgment of traffic accidents, but also help drivers and passengers to conveniently view the situation inside the vehicle when installed inside the vehicle. They can also provide strong evidence for handling issues such as disputes among passengers, finding lost items, and preventing robbery and theft. More importantly, they can monitor the environment inside and outside the vehicle in real time, providing a solid guarantee for the safe driving of the vehicle.

[0003] However, in actual use, the external environment is challenging when a car is driving in rainy or snowy weather. The waterproof performance of traditional car camera circuit boards is difficult to withstand such harsh conditions. In rainy or snowy weather, rainwater will flow along the car body. When rainwater seeps into the circuit board through the gaps, due to the lack of an effective waterproof isolation layer, the water will directly contact the electronic components on the circuit board. Therefore, in response to the above problems, a new type of waterproof car camera circuit board has been developed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a novel waterproof vehicle camera circuit board, which aims to solve the problem in the prior art that "when rain and snow seep into the circuit board through the gaps, the water will directly contact the electronic components on the circuit board due to the lack of an effective waterproof isolation layer."

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel waterproof vehicle camera circuit board, comprising a circuit board, electronic components fixedly connected to the top of the circuit board, a waterproof mechanism provided on the top of the circuit board, and a drainage mechanism provided inside the circuit board.

[0006] The drainage mechanism includes a drainage channel, which is located on the top of the circuit board. The outer wall of the circuit board has drainage holes, and the inner wall of the drainage channel is fixedly connected with ramps on all four sides. The ramps are sloping.

[0007] As a further description of the above technical solution: the waterproof mechanism includes a waterproof cover, and a side plate is fixedly connected to the outer wall of the waterproof cover.

[0008] As a further description of the above technical solution: the side plate is detachably connected to the top of the circuit board by bolts.

[0009] As a further description of the above technical solution: the number of drainage channels is four sets, and the four sets of drainage channels are respectively arranged around the top and outer wall of the circuit board.

[0010] As a further description of the above technical solution: the number of drainage holes is four sets, and the four sets of drainage holes are respectively arranged around the top and outer wall of the circuit board.

[0011] As a further description of the above technical solution: the lower end of the slope block is close to the drainage hole.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the drainage channel is used as a rainwater flow channel to guide rainwater. The slope of its inner wall is inclined and the lower end is close to the drainage hole, which changes the direction of rainwater flow. Under the action of gravity, the rainwater accelerates along the slope of the slope and flows to the drainage hole, and is discharged to the outside of the circuit board through the drainage hole, thus avoiding the accumulation of rainwater on the circuit board and further protecting the electronic components from water corrosion.

[0014] 2. In this utility model, the waterproof cover is detachably connected to the top of the circuit board via side plates and bolts, forming a relatively closed space that isolates the electronic components from the external environment, effectively blocking rainwater and preventing it from directly contacting the electronic components, thus playing a role in waterproof isolation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-3 This utility model provides an embodiment of a novel waterproof vehicle-mounted camera circuit board, comprising a circuit board 1, a waterproof mechanism 2 on the top of the circuit board 1, and an electronic component 3 fixedly connected to the top of the circuit board 1. The circuit board 1 is the core carrier of the entire vehicle-mounted camera circuit system, supporting the installation and circuit connection of the electronic component 3. The waterproof mechanism 2 includes a waterproof cover 211, which forms a relatively enclosed space, isolating the electronic component 3 from the external environment and effectively blocking rainwater. A side plate 212 is fixedly connected to the outer wall of the waterproof cover 211, providing a foundation for support and fixation of the waterproof cover 211, enhancing the stability of the waterproof cover 211. The side plate 212 is secured by bolts 213. The top of the circuit board 1 is connected to the bolt 213, which facilitates the installation and removal of the waterproof mechanism 2. This makes it easier to maintain and repair the circuit board 1 and electronic components 3 later. The top of the circuit board 1 is provided with a drainage groove 4, which serves as a channel for rainwater flow and guides the infiltrated rainwater toward the drainage hole 5. The outer wall of the circuit board 1 is provided with a drainage hole 5, which is the outlet for rainwater to exit the circuit board 1, ensuring that rainwater does not stagnate on the circuit board 1. There are four sets of drainage grooves 4 and drainage holes 5, which are respectively arranged around the top and outer wall of the circuit board 1. The multiple sets of drainage grooves 4 and drainage holes 5 expand the drainage range, improve drainage efficiency, and provide all-round protection for the circuit board 1.

[0022] Reference Figures 1-3 The inner wall of the drainage channel 4 is fixedly connected with ramps 6. The ramps 6 change the flow direction of rainwater in the drainage channel 4, making it flow more smoothly to the drainage hole 5. The ramps 6 are sloping, and the sloping shape provides a flow guide for rainwater under the action of gravity, accelerating the discharge of rainwater. The bottom end of the ramps 6 is close to the drainage hole 5, so that rainwater can flow into the drainage hole 5 with the shortest path, further improving the drainage speed. The ramps 6 are made of polytetrafluoroethylene, which has good hydrophobicity and wear resistance, preventing rainwater from adhering to the ramps 6, and ensuring that the ramps 6 are not easily damaged during long-term use.

[0023] Working principle: When the vehicle camera circuit board 1 is working, since the inner wall of the drainage channel 4 is fixedly connected with the ramp 6, and the ramp 6 is sloping, with its bottom end close to the drainage hole 5, rainwater will flow smoothly into the drainage hole 5 along the slope of the ramp 6 and be discharged to the outside of the circuit board 1 through the drainage hole 5. The synergistic effect of the four sets of drainage channels 4, drainage holes 5 and ramp 6 ensures that rainwater can be discharged quickly and smoothly, thereby preventing rainwater from accumulating on the circuit board 1 and further protecting the electronic components 3 on the circuit board 1 from water corrosion.

[0024] The waterproof cover 211 in the waterproof mechanism 2 is detachably connected to the top of the circuit board 1 via the side plate 212 and bolts 213, which serves as a waterproof barrier and effectively prevents rainwater from directly contacting the electronic components 3 on the circuit board 1. If rainwater seeps into the top of the circuit board 1, the drainage channel 4 and drainage hole 5 will come into play, and the rainwater will flow along the drainage channel 4.

[0025] 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.
