Description

Technical Field

[0001] This utility model belongs to the field of automotive electronic protection technology, specifically relating to a waterproof vehicle sensor housing. Background Technology

[0002] In the automotive industry, vehicle-mounted sensors are widely used in various monitoring and control systems to ensure the safe and stable operation of vehicles. However, vehicle-mounted sensors are usually installed on the exterior of the vehicle or in parts that are easily exposed to the external environment. During vehicle operation, they are frequently exposed to liquids such as rainwater, car wash water, and mud.

[0003] While traditional vehicle sensor housings offer some waterproofing, they suffer from structural design flaws. For instance, their surfaces are often smooth and flat, allowing water to easily stagnate and seep into weak points such as seams and cable interfaces. This can damage the electronic components inside the sensor, leading to decreased sensor performance or even failure, severely impacting the normal operation and safety of the vehicle.

[0004] Therefore, there is an urgent need to provide a waterproof vehicle sensor housing to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof vehicle sensor housing to solve the technical problem of a vehicle sensor housing that can effectively prevent water penetration from both structural and material aspects.

[0006] To solve the above-mentioned technical problems, this utility model provides a waterproof vehicle-mounted sensor housing, characterized in that it includes: a sensor housing body, one end of which is provided with a sealing end, and one end of which is provided with a cable waterproof sleeve; the surface of the sensor housing body is provided with a plurality of first oblique grooves and second oblique grooves, the first oblique grooves and second oblique grooves being symmetrical to each other and uniformly wrapped around the surface of the sensor housing body; the sensor housing body includes a base layer and an anti-penetration layer.

[0007] As further explained, the base layer and the anti-permeability layer are respectively located on the inner and outer sides of the sensor housing body, and the base layer and the anti-permeability layer are bonded together.

[0008] As further explained, the inclination angles of the first inclined groove and the second inclined groove are 55° and 125°, respectively.

[0009] As further explained, the surfaces of the first and second inclined grooves are coated with a hydrophobic coating.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The first and second inclined grooves symmetrically wrapped around the main surface of the sensor housing, with tilt angles of 55° and 125°, can quickly change the direction of water flow, allowing rainwater, mud, and other liquids to slide down the inclined grooves quickly. Compared with traditional smooth flat housings, the residence time of water on the surface is shortened by more than 80%, effectively reducing the probability of liquid seeping into seams and cable interfaces, and reducing the risk of sensor failure due to water.

[0012] 2. The double-layer structure, consisting of a base layer and an anti-permeability layer, provides waterproof protection from both the inside and outside. The base layer ensures the structural strength of the outer shell, withstanding vibrations and impacts during vehicle operation; the anti-permeability layer is tightly bonded to the outside of the base layer, effectively blocking moisture penetration and preventing water molecules from intruding from the inside of the outer shell material, further enhancing the waterproof performance of the outer shell and significantly improving the overall waterproof rating of the outer shell.

[0013] 3. The sealing end and cable waterproof sleeve provide key protection for the seams of the sensor housing and the cable interface. The sealing end can effectively seal the end of the housing body to prevent moisture from seeping in from the end. The cable waterproof sleeve tightly wraps the cable, blocking the path of moisture to enter the housing along the cable. Together with the inclined groove and double-layer structure, it forms an all-round, dead-angle waterproof system.

[0014] 4. The hydrophobic coating applied to the surfaces of the first and second inclined grooves creates a superhydrophobic interface, increasing the contact angle between water and the surface, making it easier for liquid to roll off and further enhancing drainage capacity. At the same time, the hydrophobic coating also prevents dust and dirt from adhering to the inclined grooves, avoiding blockage that could affect drainage, extending the effective waterproofing cycle of the casing, and reducing maintenance frequency.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1-2 A waterproof vehicle-mounted sensor housing includes: a sensor housing body 1, a sealing end 2 at one end of the sensor housing body 1, a cable waterproof sleeve 3 at one end of the sealing end 2, and a plurality of first inclined grooves 4 and second inclined grooves 5 on the surface of the sensor housing body 1. The first inclined grooves 4 and second inclined grooves 5 are symmetrically and evenly wound around the surface of the sensor housing body 1. The sensor housing body 1 includes a base layer 101 and an anti-permeability layer 102. The sensor housing body 1 serves as a basic frame, the base layer 101 provides structural strength, and the anti-permeability layer 102 prevents moisture intrusion. The sealing end 2 is used to seal one end of the sensor housing body 1 to prevent moisture from entering from the end; the cable waterproof sleeve 3 seals the cable interface to prevent liquid from seeping in along the cable. The first inclined grooves 4 and second inclined grooves 5 are symmetrically and evenly wound around the surface of the sensor housing body 1, and the inclined angle changes the direction of water flow, allowing liquid to slide quickly down the inclined grooves and reducing the residence time on the surface of the sensor housing body 1. The overall structure of this project is reasonable, and waterproof design is carried out in multiple key parts (ends, cable interfaces, and shell surface), forming a relatively comprehensive waterproof system. This effectively solves the technical problem of preventing water penetration in the shell of vehicle sensors from both structural and material aspects.

[0024] like Figure 2As shown, the base layer 101 and the anti-permeability layer 102 are located on the inner and outer sides of the sensor housing body 1, respectively, and are bonded together. The base layer 101 is made of high-strength materials (such as aluminum alloy or engineering plastics), possessing good impact resistance and wear resistance, providing stable support for the sensor housing body 1; the anti-permeability layer 102 is composed of a polymer waterproof material (such as polytetrafluoroethylene coating), tightly bonded to the outside of the base layer 101, forming a continuous waterproof barrier. Water molecules have difficulty penetrating this layer to enter the interior of the sensor housing body 1, thus compensating for the shortcomings of traditional single-material housings in terms of waterproof performance and further improving the overall waterproof effect.

[0025] like Figure 2 As shown, the inclination angles of the first inclined groove 4 and the second inclined groove 5 are 55° and 125°, respectively. This angle design is based on fluid mechanics principles. When liquid contacts the surface of the sensor housing body 1, the inclination angle of the inclined grooves effectively guides the water flow rapidly along the groove direction. The symmetrical setting of 55° and 125° allows the water flow to form a spiral guiding path on the surface of the sensor housing body 1, increasing the flow velocity of the water on the surface of the sensor housing body 1, reducing the possibility of water stagnation due to gravity and surface tension, maximizing the drainage function of the inclined grooves, allowing the water to flow away more smoothly, and preventing water accumulation or backflow in the inclined grooves. This improves the waterproof efficiency of the housing and further enhances the reliability of the sensor in harsh environments.

[0026] like Figure 2 As shown, the surfaces of the first inclined groove 4 and the second inclined groove 5 are coated with a hydrophobic coating. This hydrophobic coating (such as a fluoropolymer coating) increases the contact angle between water and the inclined groove surface by reducing surface energy, creating a superhydrophobic effect. Liquids can form spherical shapes on the coating surface, resulting in minimal rolling friction and easier rolling down the inclined grooves. The application of the hydrophobic coating further enhances the hydrophobicity of the inclined grooves, enabling them to more effectively drain water. Even when a small amount of water comes into contact with the inclined grooves, the hydrophobic coating can quickly remove water droplets, reducing water accumulation within the inclined grooves and thus lowering the risk of water seeping into the sensor housing 1.
