[0007] A drainage structure is provided on the side of the top cover facing the mounting surface. The drainage structure extends from the area where the ventilated structure is located to the edge of the top cover to guide the liquid around the ventilated structure away from the ventilated structure and prevent the ventilated structure from being blocked.

[0008] In some embodiments, the breathable structure includes at least one breathable hole and a breathable membrane, the breathable hole penetrating the top cover in the thickness direction, and the breathable membrane and the breathable hole being disposed adjacent to each other in the thickness direction;

[0010] In some embodiments, the drainage structure includes at least one annular waterway and at least one guide channel;

[0011] The annular water channel is arranged around the vent hole. The annular water channel is a closed loop structure. One end of each guide groove is connected to the annular water channel, and the other end extends to the corresponding edge of the top cover.

[0012] In some embodiments, the annular waterway includes multiple fluid channels connected end to end, and the multiple fluid channels together form a non-circular groove structure on the surface of the top cover;

[0013] A junction is formed between each pair of fluid channels, and each junction is connected to a flow guide channel.

[0014] In some embodiments, the top cover forms a corresponding boss through the embedded arrangement of the annular water channel, and the annular water channel surrounds the boss;

[0015] The ventilation holes are all located in the area within the edge of the boss. The fluid channels are one or a combination of arc-shaped, curved, and zigzag-shaped configurations. Each fluid channel protrudes towards the corresponding edge of the boss, so that the edge of the boss has a concave profile from the outside to the center.

[0016] In some embodiments, the cross-sectional profile of the fluid channel is V-shaped or U-shaped;

[0017] And / or, the cross-sectional profile of the guide channel is V-shaped or U-shaped.

[0018] In some embodiments, the number of the guide channels is four, and the annular water channel is located at the center of the top cover;

[0028] By incorporating a ventilated structure on the top cover, air convection is created between the radar housing and the external environment, which helps to promptly release the heat generated during radar operation and improves overall heat dissipation efficiency. Furthermore, a drainage structure is installed around the ventilated structure, extending from its center towards the edge of the top cover. In the presence of moisture, rain, or condensation in the external environment, this effectively guides liquid away from the ventilated area, reducing the likelihood of liquid adhering to or stagnating around the ventilated structure, preventing blockages, ensuring unobstructed heat dissipation channels, and enhancing the reliability and stability of the radar device in humid, rainy, or high-humidity environments.

Obviously, the accompanying drawings described below are only some embodiments of this application.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Radar devices, as important detection and monitoring equipment, are widely used in various fields such as vehicle driver assistance, security monitoring, and industrial inspection. In practical applications, to ensure the stable operation of the internal electronic components of the radar and extend their service life, radar devices are usually encapsulated in a sealed housing and equipped with corresponding heat dissipation structures to achieve timely heat release.

[0046] Currently, a common heat dissipation method is to incorporate perforated structures such as ventilation holes and slots into the radar casing to improve heat dissipation efficiency through air convection. These structures typically combine breathability and dust protection, effectively balancing the radar device's sealing and heat dissipation performance in non-extreme environments.

[0047] However, in certain humid, rainy, or high-moisture environments, such as coastal areas, construction sites during the rainy season, and high-humidity vehicle environments, moisture in the air easily condenses or accumulates on the radar casing surface, adhering to it. When water droplets or moisture block the perforated structures on the casing used for heat dissipation, it not only severely affects air convection and heat dissipation but may also cause excessive internal temperature rise, affecting the operational stability and signal accuracy of the radar module. In more serious cases, moisture infiltration may induce corrosion of internal components, short circuits, and other safety hazards.

[0048] In one embodiment, refer to the appendix to the specification. Figures 1 to 4 This application describes a radar housing that can ensure the heat dissipation performance and operational stability of the radar device in a humid environment.

[0049] Reference manual attached Figure 1 and Figure 3 This application provides a radar housing, comprising a housing body 1, a venting structure 30, and a drainage structure 40. The housing body 1 has an accommodating chamber 100 and a top cover 11. The accommodating chamber 100 is used to install internal radar components, such as a signal transmitting unit, a receiving unit, a signal processing module, and a power management module. (Refer to the attached drawing.) Figure 2 Under normal use, the top cover 11 is installed on the corresponding mounting surface 20.

[0050] In order to meet the heat dissipation requirements of internal components, a ventilated structure 30 is provided on the top cover 11. The ventilated structure 30 is connected to the accommodating chamber 100 of the housing body 1, so that air convection can be carried out between the inside of the housing and the external environment, heat exchange can be realized, and the overall heat dissipation performance of the radar device can be improved.

[0051] However, in actual use, especially in outdoor environments where the radar device is in a humid environment, with frequent rain or a risk of condensation, moisture can easily accumulate on the surface of the housing and adhere to the ventilation structure 30 around the top cover 11. This can cause the ventilation structure 30 to be covered or even blocked by water film or water droplets. In severe cases, this can obstruct air convection, affect the heat dissipation of internal components, and thus affect the radar's detection performance and service life.

[0052] To this end, this embodiment further provides a drainage structure 40 on the top cover 11 to guide the liquid accumulated around the ventilated structure 30 to flow away from the ventilated structure 30. Specifically, the drainage structure 40 is located on the side of the top cover 11 facing the mounting surface 20, and extends outward along the surface of the top cover 11 with the area where the ventilated structure 30 is located as the center. This forms a natural liquid drainage path, effectively preventing liquid from stagnating around the ventilated structure 30, thereby reducing the risk of poor heat dissipation caused by the ventilated structure 30 being blocked.

[0053] Through the above structural design, this utility model effectively solves the problem of the ventilation structure 30 being blocked due to humid environments in the prior art while ensuring good heat dissipation performance of the radar housing, thereby improving the operational stability and reliability of the radar device in harsh environments.

[0054] In the specific implementation process, the breathable structure 30 can be set up with structural forms that have both ventilation function and certain protective performance, such as microporous membrane, metal screen, and filter sheet, and combined with sealing ring or waterproof layer to enhance the overall protective performance.

[0055] Alternatively, the drainage structure 40 can be implemented in the form of a guide ramp, radial channel, liquid guiding rib, etc., or it can be curved according to the shape of the top cover 11 to enhance the drainage efficiency and take into account the appearance design requirements.

[0056] Furthermore, to prevent water vapor from remaining in the drainage path for a long time, a hydrophobic coating or similar structure can be installed in the drainage structure 40 to enhance drainage capacity.

[0057] In one embodiment, based on the above embodiments, refer to the appendix to the specification. Figure 5 The ventilated structure 30 includes at least one vent 300 and a ventilated membrane 301. The vent 300 penetrates the top cover 11 in the thickness direction, so that the interior of the shell is connected to the external environment to achieve ventilation and heat dissipation. The ventilated membrane 301 is arranged adjacent to the vent 300 in the thickness direction. Specifically, the ventilated membrane 301 is located on the side of the top cover 11 facing the accommodating chamber 100 and at least covers the area where the vent 300 is located, thereby forming an effective protective barrier.

[0058] Understandably, in this structure, the breathable membrane 301 is positioned inside the top cover 11, that is, it is attached to the surface opposite to the accommodating chamber 100, forming a structural design similar to "one-sided puncture". Through this configuration in this embodiment, when a sharp object contacts or impacts the outer surface of the top cover 11, the breathable membrane 301 will not be directly exposed to the impact source, effectively preventing puncture or tearing. This enhances the protective strength and reliability of the breathable membrane 301 during long-term use and significantly reduces the risk of failure of the breathable membrane 301 due to external force damage.

[0059] In addition, since the breathable membrane 301 is attached to the inner surface of the top cover 11, its installation process is easy to control, and it is also easier to use with sealant, support mesh structure, etc. to enhance the bonding firmness and improve durability.

[0060] In practical applications, the breathable membrane 301 can be made of waterproof and breathable materials with microporous structures, such as PTFE membranes and PU membranes. While having high breathability, it also has excellent liquid barrier properties, which can effectively prevent rainwater, condensate and other liquids from entering the shell through the breathable holes 300.

[0061] Optional, as shown in the appendix Figure 6 In some embodiments, the structure may include two or more vents 300, which cooperate with a common breathable membrane 301, covering one side of each of the vents 300. This structural design simplifies the number of membranes and installation procedures, reduces production costs, and ensures sufficient ventilation area.

[0062] The multiple vents 300 can be arranged in a regular pattern, in an array, or in a uniform arrangement such as a circle or arc. The specific number and location of the vents can be flexibly adjusted according to the actual heat dissipation requirements and the size of the top cover 11.

[0063] Furthermore, in one embodiment, such as Figure 6 As shown, the drainage structure 40 includes at least one annular water channel 401 and at least one guide channel 402. The annular water channel 401 is a closed loop structure surrounding the area surrounding the vent 300. It should be noted that the annular water channel 401 can be circular, elliptical, or other closed curves to form a liquid collection area around the vent 300. When moisture accumulates on the surface of the top cover 11, some liquid flows towards the vent 300 along the direction of surface tension or gravity. Without a drainage structure, this can easily cause liquid accumulation and block the venting channel. In this application, by providing the annular water channel 401, effective collection of liquid in this area can be achieved, preventing liquid from directly covering the opening of the vent 300.

[0064] Each guide channel 402 has one end connected to the annular water channel 401 and the other end extending to the corresponding edge of the top cover 11, used to discharge liquid from the annular water channel 401 to the outside. The guide channel 402 can be arranged radially along the outer surface of the top cover 11 to form a drainage channel expanding outward from the center, allowing water to be naturally discharged to the outer periphery of the shell under the action of gravity, thereby preventing liquid from staying around the vent hole 300 for a long time.

[0065] The combined design of the annular water channel 401 and the guide channel 402 provides excellent drainage, helping to ensure the continued effectiveness of the permeable structure 30 under extreme conditions such as heavy rain, high humidity, or continuous condensation. Furthermore, the number and arrangement of the guide channels 402 can be flexibly determined according to actual needs. For example, two or more guide channels 402 can be symmetrically arranged to accommodate top cover 11 structures of different sizes and shapes, further improving drainage efficiency.

[0066] It should be noted that the flow guide trough 402 can be optimized based on different usage environments, including key parameters such as its depth, width, and tilt angle. The depth must balance structural strength and drainage efficiency. Insufficient depth limits flow guidance, and in cases of heavy rainfall or severe condensation, liquid stagnation can easily occur, affecting drainage speed. Conversely, excessive depth may increase the overall thickness of the top cover 11, affecting structural compactness and potentially leading to dust accumulation that is difficult to clean over long-term use. Therefore, a suitable trough depth should be selected based on the radar housing material strength, housing dimensions, and application environment to ensure smooth liquid drainage along the path of least resistance.

[0067] Similarly, the opening width of the guide channel 402 also affects drainage efficiency and liquid flow rate. Generally, increasing the width can effectively increase the drainage volume per unit time, especially suitable for environments with heavy rainfall or frequent water vapor condensation. However, the overall surface strength and structural aesthetics of the casing must also be considered to avoid the channel width being too large, affecting the sealing surface or causing local deformation of the casing.

[0068] In one embodiment, preferably, the bottom surface of the guide channel 402 can also be designed with a certain inclination angle relative to the edge of the top cover 11, that is, forming a flow channel with a gradually decreasing slope from the annular water channel 401 to the edge of the top cover 11. This inclination angle can be formed by integrally molding the structure of the top cover 11, or by setting a certain slope through local processing, so that the liquid can be accelerated to flow by gravity, thereby improving the drainage response speed and reducing liquid accumulation.

[0069] In one embodiment, refer to the appendix to the specification. Figure 7The annular waterway 401 in the drainage structure 40 includes multiple fluid channels 4010 connected end to end. The fluid channels 4010 are interconnected and arranged around the area where the vent 300 is located, together forming a non-circular groove structure on the surface of the top cover 11. For example, it can be a polygonal or irregular closed loop structure, which is convenient for matching design according to the geometry of the top cover 11 and the internal layout space of the actual product, thereby improving the structural utilization rate.

[0070] Specifically, each fluid channel 4010 is arranged on the surface of the top cover 11. Its depth and width can be set according to the drainage requirements, and it is connected end to end with the adjacent fluid channel 4010 to form a closed path.

[0071] At the junction of multiple fluid channels 4010, i.e. the intersection point formed between every two fluid channels 4010, a guide channel 402 is provided, which is connected to the guide channel 402. This allows the liquid to flow and converge in the annular waterway 401 to the intersection point and then be discharged to the edge of the top cover 11 through the guide channel 402 in a timely manner, thereby preventing the liquid from stagnating or flowing back between the channels.

[0072] Understandably, since the junction is usually located at the turning point of the fluid path or the local liquid accumulation point, setting the guide channel 402 here is beneficial to enhance the local drainage efficiency.

[0073] In this embodiment, by segmenting the annular waterway 401 into multiple fluid channels 4010 and setting a guide channel 402 at each confluence point, a multi-path drainage network can be formed, preventing drainage failure due to blockage of a single path by foreign objects. Furthermore, compared to traditional annular waterways 401 that can only form a circle or ellipse, this embodiment employs a multi-segment channel combination design, which can flexibly construct polygonal or asymmetrical closed-loop structures to meet the characteristics of different radar housing designs.

[0074] Based on the above embodiments, in one embodiment, more specifically, the cross-sectional profile of the fluid channel 4010 can be designed as a V-shaped or U-shaped structure to adapt to different processing techniques and drainage efficiency requirements. The V-shaped cross-sectional structure has strong flow guiding capabilities, forming a distinct lowest point in the channel, thereby promoting natural liquid convergence along the bottom of the tank. In contrast, the U-shaped structure has a larger liquid capacity, suitable for applications handling large volumes of liquid or significant condensate accumulation, while also being easy to clean and less prone to dust accumulation, exhibiting better overall drainage and maintenance performance.

[0075] Similarly, the cross-sectional profile of the flow guide 402 can also be V-shaped or U-shaped, and can be matched with the cross-sectional shape of the fluid channel 4010 or set independently to meet specific structural layout requirements. The V-shaped flow guide 402 is conducive to forming a strong flow guiding force, which can achieve rapid liquid drainage under the action of gravity and reduce the risk of liquid stagnation or lateral diffusion during the drainage process. The U-shaped flow guide 402 provides a larger cross-sectional area, and its smooth inner wall and rounded transition help to avoid liquid stagnation in the channel and improve the overall drainage efficiency.

[0076] In addition, the V-shaped and U-shaped cross sections facilitate mold processing and can be formed by injection molding, die casting or integral stamping processes, which can simplify the manufacturing process and improve product consistency while ensuring smooth drainage.

[0077] It should be noted that in other embodiments, the cross-sectional profiles of the fluid channel 4010 and the guide groove 402 can be designed specifically according to the actual usage environment, which will not be elaborated here.

[0078] In one embodiment, the top cover 11 forms a corresponding boss 110 by an embedded annular water channel 401, the annular water channel 401 surrounds the boss 110, and the vent holes 300 are all located in the area within the edge of the boss 110.

[0079] In other words, the top cover 11, through the embedded arrangement of the annular water channel 401, forms a closed groove structure with a recessed arrangement on its surface. This structure surrounds an area enclosed by the annular water channel 401, which is the area where the ventilated structure 30 is concentrated, with protrusions 110. It should be noted that the "protrusions 110" in this embodiment do not protrude relative to the top cover 11, but rather, due to the recessed design of the annular water channel 401, a relatively higher area is naturally formed on its inner side, hence the name "protrusions," serving as the functional arrangement area of ​​the ventilated structure 30.

[0080] All vents 300 are located within the edge of the boss 110, that is, within the area enclosed by the annular water channel 401. This arrangement allows rainwater, condensate, or other liquids to slide along the surface of the top cover 11 under gravity and preferentially flow into the recessed annular water channel 401, thereby preventing liquid from continuing to penetrate into the central area of ​​the boss 110, reducing the possibility of liquid covering the vents 300, and significantly reducing the risk of failure of the vents 300.

[0081] Furthermore, and more importantly, each fluid channel 4010 can be one or more of the following forms: arc-shaped, curved, or zigzag-shaped. Each fluid channel 4010 protrudes towards the edge of the surrounding boss 110, so that the edge of the boss 110 has a concave profile from the outside to the center. This not only enhances the ability of the annular waterway 401 to gather the surrounding liquid, but also allows the liquid to naturally flow along the concave edge into the guide groove 402, preventing the liquid from overflowing or stagnating in the central area.

[0082] Understandably, this arrangement in this embodiment causes the annular waterway 401 to form multiple arc segments or bends that cut towards the center during the process of surrounding the boss 110, which effectively increases the flow rate and efficiency of the fluid as it converges at each intersection point in the surrounding path.

[0083] Compared to the traditional straight-line arrangement, the curved or zigzag-shaped annular waterway 401 in this embodiment has a certain angular guidance and flow-guiding properties, which can form a stronger dynamic flow path, allowing the liquid to concentrate at each confluence point more quickly. At the same time, since a confluence point is formed between every two adjacent fluid channels 4010, and each confluence point is connected to a guide channel 402, multi-point uniform drainage can be achieved, avoiding local liquid accumulation.

[0084] In one embodiment, as shown in the accompanying drawings of this application, there are four guide channels 402, and an annular water channel 401 is located at the center of the top cover 11. The top cover 11 has a rectangular outline, which can be understood as the top cover 11 being approximately rectangular or square in overall shape. The four guide channels 402 are symmetrically arranged with the annular water channel 401 as the center and extend to the four different edges of the top cover 11, so that the entire drainage structure 40 presents a cross-shaped symmetrical layout on the top cover 11.

[0085] The cross-shaped arrangement structure in this embodiment has several technical advantages. First, by uniformly arranging four guide channels 402 around the annular water channel 401, liquid can be quickly discharged from the nearest channel when it accumulates in any direction, significantly improving drainage efficiency and structural adaptability. Second, the centrally symmetrical arrangement avoids the drainage direction bias caused by the single-sided guide channel, which helps to reduce local liquid accumulation, improve drainage balance, and further prevent water from flowing back or stagnating around the breathable structure 30.

[0086] Furthermore, the cross-shaped flow guide path arranged on the rectangular top cover 11 helps to reserve space for internal wiring and divide functional modules. The arrangement direction of the four flow guide channels 402 corresponds to the four boundaries of the top cover 11, which is beneficial for orientation in combination with radar installation direction or natural drainage slope; at the same time, it can also have good symmetry and stress balance in mold forming, integrated injection molding or stamping process of shell, with simple manufacturing process and high structural strength.

[0087] In one embodiment, please refer to the appendix to the specification. Figure 3 The housing body 1 also includes a hollow bottom shell 12, and the top cover 11 is fixedly connected to the bottom shell 12. The two together form an accommodating chamber 100 for installing various core functional components or electronic components of the radar.

[0088] Understandably, in this embodiment, the top cover 11 and the bottom shell 12 in the housing body 1 are separated to facilitate separate molding and independent arrangement and assembly of internal modules.

[0089] Please refer to the instruction manual attached. Figure 3 , Figure 4 , Figure 5 and Figure 8 To ensure the relative positioning accuracy between the top cover 11 and the bottom shell 12 during the assembly process, in this embodiment, a corresponding positioning structure 50 is provided between the top cover 11 and the bottom shell 12. The positioning structure 50 is respectively provided on one or several sides of the top cover 11 and the corresponding edge of the bottom shell 12. It can realize functions such as mutual correspondence and limiting insertion during the assembly process, thereby effectively ensuring the assembly accuracy and sealing between the top cover 11 and the bottom shell 12.

[0090] Referring to the accompanying drawings, in this embodiment, the positioning structure 50 is provided with a protrusion on one side edge of the top cover 11 and a corresponding recess on one side edge of the bottom shell 12. Of course, in other embodiments, guide posts-positioning holes, stepped fitting, etc. can also be used. On the one hand, this improves assembly efficiency and avoids poor assembly caused by misalignment or offset. On the other hand, the limiting fit of the docking parts also facilitates the precise correspondence of functional areas such as the annular waterway 401, the guide channel 402, and the ventilated structure 30 between the two shells, thereby improving the overall structural function synergy and environmental adaptability.

[0091] In one embodiment, such as Figure 4 and Figure 5As shown, in one embodiment, the top cover 11 is provided with a reinforcing rib structure 111 on the side facing the accommodating chamber 100. The reinforcing rib structure 111 is a reinforcing structure protruding from the inner surface of the top cover 11, which is used to partially or completely reinforce the top cover 11 body, improve the mechanical strength and deformation resistance of the top cover 11 during long-term use of the radar device, prevent the top cover 11 from warping, bulging or deforming, thereby ensuring the tight fit between the top cover 11 and the bottom shell 12 and the sealing of the accommodating chamber 100.

[0092] It should be noted that the reinforcing rib structure 111 can be arranged longitudinally, laterally, or in a regular or irregular manner, such as a grid or radial pattern. Its specific shape can be customized according to the area of ​​the top cover 11, the material strength, and the stress distribution characteristics. For example, for a rectangular top cover 11 structure with a longer side, reinforcing ribs extending along the longer side can be prioritized to enhance the longitudinal bending resistance of the panel. For top covers 11 where stress is concentrated in the central area, reinforcing ribs can also be arranged in a cross pattern in the central area to form a stress buffer and diffusion effect, thereby improving the overall structural performance.

[0093] In one embodiment, refer to the appendix to the specification. Figures 1 to 3 According to another aspect of this application, this application further provides a radar, which includes a radar housing, a main body 60 and a data connector 70 as described in any of the above embodiments. The main body 60 is disposed within the receiving cavity 100 of the radar housing, and the data connector 70 is electrically connected to the main body 60 to perform data communication with an external host.

[0094] Understandably, by adopting the radar housing described above in this embodiment, the heat dissipation performance of the radar is ensured. The ventilated structure 30 helps to release the heat generated during the operation of the radar in a timely manner.
