[0039] The technical solution in this application will be described below with reference to the accompanying drawings.

[0040] See also Figure 1 , Figure 1 1 is a schematic diagram of a possible application scenario applicable to an embodiment of the present application. The system in this application scenario includes one or more radar devices and a target device that interacts with the radar device.

[0041] Radar is an electronic device that uses electromagnetic waves to detect targets. It's also called a radar device, a detector, or a detection device. Its operating principle is that a radar transmitter emits electromagnetic waves (also called a transmission signal or a detection signal) that illuminate a target and receive the echo signal reflected by the target. This information provides information such as the distance from the target to the point of emission, the rate of change of distance (radial velocity), direction, and altitude.

[0042] See also Figure 2 , Figure 2 This is a typical appearance and structure diagram of a vehicle-mounted millimeter-wave radar. Figure 3 , Figure 3 This is a typical structural diagram of an on-board millimeter-wave radar. Existing on-board millimeter-wave radars are generally independent products that are installed or integrated into the vehicle and connected or associated with other components in the vehicle to achieve corresponding detection functions for the vehicle. Figure 3 As shown, an automotive millimeter-wave radar consists of a radome, antenna board, digital board, shielding structure, lower housing, and connector. These components are assembled together using screws, rivets, or adhesives. The radome is made of non-metallic materials. Besides meeting vehicle engineering requirements, such as mechanical strength, it must also meet the electromagnetic propagation characteristics of the radar's millimeter waves.

[0043] Figure 4 This is a schematic diagram of possible vehicle installation locations for automotive millimeter-wave radars. These radars are typically installed within the vehicle's exterior, i.e., within the vehicle's cladding. They are directly fixed to the vehicle frame or cladding using screws or clips, using auxiliary mounting adapters, etc. This requires additional mounting support systems (components). Similar to the requirements for the radome, the cladding on the outside of the automotive millimeter-wave radar must be made of a non-metallic material that not only meets vehicle engineering requirements but also electromagnetic wave transmission characteristics.

[0044] See also Figure 5 , Figure 5 This is a schematic diagram of a vehicle-mounted millimeter-wave radar installed on a vehicle frame. The vehicle-mounted millimeter-wave radar is mounted on the vehicle frame via a bracket.

[0045] See also Figure 6 , Figure 6 This is a schematic diagram of the vehicle-mounted millimeter-wave radar installed on the skin. Figure 5 The difference in installation is that the vehicle-mounted millimeter-wave radar is installed on the vehicle skin.

[0046] Figure 5 and Figure 6 In both of the two vehicle-mounted radar installation methods shown, the radars are not directly observable. Due to different vehicle appearance requirements from different automakers, radar performance is often not fully utilized to accommodate the vehicle's appearance, resulting in performance loss. To ensure the electromagnetic propagation characteristics of the vehicle-mounted millimeter-wave radar, ideally, constraints and requirements are required on the shape of the skin directly in front of the vehicle-mounted millimeter-wave radar, such as a flat design made of a uniform non-metallic material. However, this design constraint often conflicts with the vehicle's exterior design or results in a suboptimal exterior design.

[0047] In addition, on the vehicle production line, the on-board millimeter-wave radar requires a dedicated workstation for the installation and debugging of the on-board millimeter-wave radar, which increases production time; the installation auxiliary parts of the on-board millimeter-wave radar increase the number of accessories on the vehicle production line and increase the accessories management cost of the vehicle production line.

[0048] In view of this, the present application proposes a detection device that can achieve better millimeter wave propagation performance while reducing the management cost of existing vehicle-mounted millimeter wave radar installation accessories.

[0049] Figure 7 This is a schematic diagram of a detection device provided in an embodiment of the present application.

[0050] The detection device includes a skin (i.e., an example of a skin structure), an antenna plate (i.e., an example of a first antenna plate), a digital board (i.e., an example of a first digital device), a shielding structure (i.e., an example of a first shielding device), and a lower shell (i.e., an example of a shell). The skin and the lower shell are integrated into a first cavity, and a first cavity is formed between the skin and the lower shell. The antenna plate, digital board, and shielding structure are all located in the first cavity. The first cavity is a sealed cavity, and the integrated design of the skin and the lower shell must meet vehicle engineering requirements, such as waterproofing requirements, impact resistance requirements, and full-temperature operation requirements.

[0051] It should be noted that the integrated design is a connection method different from the fixed connection (or connection or connection) mentioned above. For example: the fixed connection of parts A and B means that parts A and B are combined by screws, rivets, bonding, snaps or welding, etc., and the combination can be disassembled again without destroying the original structure of parts A and B. The integrated design of parts A and B means that parts A and B themselves are a whole and cannot be disassembled without destroying the original structure of parts A and B.

[0052] Exemplarily, for "fixed connection", one element can be directly or indirectly fixedly connected to another element; fixed connection can include mechanical connection, welding and bonding, among which mechanical connection can include riveting, bolt connection, threaded connection, key connection, snap connection, lock connection, plug-in connection and other methods, and bonding can include adhesive bonding and solvent bonding and other methods.

[0053] For example, the term "connected" or "connected" may refer to various connection modes, such as fixed connection, rotational connection, flexible connection, movable connection, electrical connection, etc. It may be directly connected, or indirectly connected through an intermediate medium, or it may be internal communication between two elements or an interaction relationship between two elements.

[0054] Optionally, in the first cavity, at least one of the above-mentioned antenna board, digital board and shielding structure is fixedly connected to the skin, and the remaining components of the above-mentioned antenna board, digital board and shielding structure are fixedly connected to the lower shell constituting the first cavity; or the above-mentioned antenna board, digital board and shielding structure are all fixedly connected to the lower shell constituting the first cavity, or the above-mentioned antenna board, digital board and shielding structure are all fixedly connected to the skin structure.

[0055] Optionally, the skin in the present application may be a planar structure, a non-planar structure, or a streamlined structure, etc. For example, the non-planar structure may be a curved structure, or a structure with partial protrusions and / or depressions on the basis of a planar or curved structure.

[0056] It should be noted that the skin shape, local thickness and processing requirements in the embodiments of this application need to be designed and optimized according to specific circumstances, and this application does not make specific limitations.

[0057] Depend on Figure 3 and Figure 7 By comparison, this detection device retains the antenna board, digital board, shielding structure, and lower housing of traditional automotive millimeter-wave radars. It replaces the radome with a skin structure, integrating the radome and skin into one, effectively eliminating the need for the traditional radome, thereby achieving better millimeter-wave propagation performance. Furthermore, the integrated design of this detection device eliminates the traditional installation process of the millimeter-wave radar module and auxiliary structural components on the vehicle equipment production line, reducing the cost of managing installation accessories.

[0058] It should be noted that when Figure 7 When the skin structure is a non-planar structure and the antenna board is a planar antenna board, there is a possibility that the space behind the vehicle skin is small, which may make it impossible to install the planar antenna board. In practice, there are constraints and requirements on the shape of the skin directly in front of the detection device, which affects the appearance of the vehicle. Therefore, this application proposes another detection device that can reduce the impact on the appearance of the vehicle.

[0059] See also Figure 8 , Figure 8 This is a schematic diagram of the structure of another detection device provided in an embodiment of the present application. For ease of description, Figure 8 Only the schematic diagram of the antenna board as two separate antenna boards is given. Figure 7 The difference between the integrated design of the detection device and the detection device is that the antenna plate of the detection device can be designed in a split manner according to the shape of the skin.

[0060] Optionally, the antenna board may be an independent antenna board; or the antenna board may be composed of at least two independent antenna boards, and the first angle may be formed between two connected antenna boards of the at least two independent antenna boards.

[0061] It should be understood that the independent antenna board here refers to an integrally formed antenna board.

[0062] It should be understood that the first angle can be any angle, and the specific size of the first angle needs to be determined based on the appearance of the vehicle skin in actual production, and this application does not limit it.

[0063] Optionally, any single antenna board in the antenna board can be a planar antenna board, or a non-planar antenna board. Figure 8 The two antenna panels of the central split body may both be planar antenna panels, or both be non-planar antenna panels, or one of the antenna panels may be a planar antenna panel and the other a non-planar antenna panel.

[0064] Optionally, the non-planar antenna panel includes an antenna panel having a regular curved surface, an irregular curved surface, or a folded surface at a certain angle. For example, the two separate antenna panels can be identical non-planar antenna panels, or one antenna panel can have a regular curved surface and the other a folded surface at a certain angle.

[0065] Optionally, the two connected antenna panels can be connected via a high-speed interconnection device to achieve signal communication. For example, the high-speed interconnection device can be a flexible cable or a printed circuit board (PCB). The detection device in this embodiment can optimize the structure of the antenna panel based on the vehicle's appearance. A split antenna panel can be used behind the skin structure to replace the original flat antenna panel, thereby reducing the impact of the antenna panel on the vehicle's appearance.

[0066] In addition, the split antenna board can also achieve large-angle coverage, making the antenna's radiation angle wider, and further improving the quality of the antenna's radiation signal based on the integrated design.

[0067] Optionally, a second cavity can be formed between the antenna plate and the skin structure in the detection device of all embodiments of the present application, wherein the opening of the second cavity on the antenna plate side is smaller than the opening of the second cavity on the skin structure side. This design is to make the inner surface of the second cavity present an inclined structure, which is used to ensure that there is no structural interference with the antenna plate within the designed field of view (FOV), thereby improving the antenna radiation and reception signal quality.

[0068] Optionally, the inner surface of the second cavity can be a planar design or a non-planar design. For example, the inner surface of the second cavity can be a smooth planar design structure, or the inner surface of the second cavity can be a non-planar design structure such as a corrugated, wavy or curved surface.

[0069] As another implementation, the inclined inner surface of the second cavity may be covered with millimeter wave absorbing material, or the inclined inner surface may be directly made of millimeter wave absorbing material to improve antenna radiation and reception signal quality.

[0070] Optionally, the second cavity may be a sealed cavity structure, or may be a non-sealed cavity structure. For example, the non-sealed cavity structure may be a honeycomb cavity structure.

[0071] See also Figure 9 , Figure 9 It is a structural schematic diagram of the second cavity formed between the antenna plate and the skin provided in this embodiment.

[0072] Optional, such as Figure 9 As shown, the antenna plate and the skin structure are both planar structures, forming a second cavity between the antenna plate and the skin. Optionally, the inner surface of the second cavity is inclined. The morphology and structure of the second cavity are described above and will not be repeated here.

[0073] Optionally, the distance between the antenna plate and the skin can be ensured by structural members such as limiters to ensure the physical distance size.

[0074] In the above technical solution, the integrated design of the detection device can ensure the spacing accuracy between the skin structure and the antenna plate, thereby improving the performance of the millimeter wave radar.

[0075] See also Figure 10 , Figure 10 It is a structural schematic diagram of the second cavity formed between the antenna plate and the skin structure in the antenna plate split detection device provided in an embodiment of the present application.

[0076] Optionally, the skin structure is non-planar, allowing the two separate antenna panels to form any angle, and interconnected to form a complete skin-integrated detection device. A second cavity is formed between the separate antenna panels and the skin structure. The morphology and structure of this second cavity are described above and will not be further elaborated here.

[0077] Optionally, the distance between the antenna plate and the skin structure can be ensured by structural members such as limiters to ensure the physical distance size.

[0078] Figure 9 and Figure 10The integrated detection device in the system can ensure the spacing accuracy between the skin structure and the antenna plate, thereby improving the performance of the millimeter-wave radar.

[0079] It should be understood that Figure 7 The structural diagram of only one lower shell is shown as an example. The detection device may also include multiple lower shells. This is for example and not for limitation. Figure 11 A schematic structural diagram of a detection device comprising two lower shells is given in FIG.

[0080] See also Figure 11 , Figure 11 This is a structural diagram of another detection device provided in an embodiment of the present application.

[0081] and Figure 7 The difference between the detection device in the embodiment is that the detection device in this embodiment includes two lower shells. The two lower shells are respectively integrated with the skin structure, and the two lower shells respectively form a first cavity with the skin corresponding to the two lower shells, and the first cavity includes an antenna board, a digital board and a shielding device. Optionally, the two lower shells are located on the same side of the skin structure and are connected through a high-speed interconnection device that meets protection requirements such as waterproofing to achieve signal intercommunication. For example: when there are multiple radar splits, the multiple radar splits can be connected together in series or parallel through a high-speed interconnection device, and this application does not make specific limitations on this.

[0082] For the sake of convenience in description, the parts formed by the skin and the two lower shells are respectively referred to as radar split one and radar split two.

[0083] Optionally, the structures of the two radar subunits in this embodiment may be the same or different. For example, the two radar structures may differ in that the antenna board in radar subunit one is a flat antenna board, and the inner surface of the second cavity corresponding to the antenna board and the skin of radar subunit one is a flat design, while the antenna board in radar subunit two is an antenna board with a folded surface at a certain angle, and the inner surface of the second cavity corresponding to the antenna board and the skin of radar subunit two is a corrugated structure.

[0084] The detection device in this embodiment can be structurally optimized according to the vehicle appearance design, and adopts multiple radar splits combined with high-speed interconnection to form a complete skin-integrated detection device. This structural form is more adapted to the structural shape of the skin and reduces the impact on the vehicle appearance.

[0086] Optionally, the first antenna board is an independent antenna board or the first antenna board is composed of at least two independent antenna boards, and two connected antenna boards among the at least two independent antenna boards can form a first angle.

[0087] It should be understood that the first angle can be any angle, and the specific size of the first angle needs to be determined based on the appearance of the vehicle skin in actual production, and this application does not limit it.

[0088] Optionally, the individual antenna boards in the first antenna boards are planar antenna boards or non-planar antenna boards, and the non-planar boards include regular curved surfaces, irregular curved surfaces, or folded surfaces with a certain angle.

[0089] Optionally, a second cavity is formed between the first antenna board and the skin structure.
