[0049] As the development of unmanned autonomous driving gradually extends to special vehicles such as sanitation sweepers, logistics vehicles, and express delivery vehicles, today's unmanned vehicles are basically equipped with various vehicle-mounted radar applications such as laser radar, millimeter-wave radar, and ultrasonic radar, mainly for the different operations of special vehicles, and the functions achieved are also different. Basically, it realizes the positioning of the forward direction, the edge detection of curbstones and the detection of obstacles in front, the forward collision warning, adaptive cruise, lane change reminder, blind spot detection and other functions, forming a complete front and side assistance system, thereby assisting the vehicle to realize the advanced driving assistance system.

[0050] Therefore, in order to meet different needs, multiple radars need to be installed on the vehicle, but one mounting structure can only meet the installation of one radar. At present, different types of radars require different mounting structures, resulting in more and more complex overall mounting structures when installing multiple radars. The types of radars that can be installed on a single mounting structure are single, and the installation efficiency is low.

[0051] To solve the above technical problems, Figures 1 to 5 As shown, an embodiment of the present application provides a radar installation structure, which includes:

[0052] A mounting base plate 1, used for fixing on a vehicle body;

[0053] A laser radar fixing frame 10 is fixedly mounted on both ends of the mounting substrate 1, and a laser radar 6 and a first ultrasonic radar 7 are fixedly mounted on the laser radar fixing frame 10;

[0054] The millimeter wave radar fixing frame 2 is fixedly arranged in the middle of the mounting substrate 1, and the millimeter wave radar 8 is fixedly arranged on the millimeter wave radar fixing frame 2;

[0055] The second ultrasonic radar 3 is fixedly mounted in the middle of the mounting substrate 1 .

[0056] In this embodiment, the radar mounting structure is mainly composed of a mounting substrate 1, a laser radar fixing frame 10 and a millimeter wave radar fixing frame 2. The mounting substrate 1 is used as the mounting base for the two types of radar fixing frames. The mounting substrate 1 is an elongated structure as a whole and can be adapted to the position to be installed on the vehicle. The laser radar fixing frame 10 is installed at both ends of the mounting substrate 1, corresponding to the A-pillar positions on both sides of the vehicle. At least one laser radar 6 can be installed on the laser radar fixing frame 10 at each end, and the laser radar 6 is used to detect the environmental information near the A-pillar of the vehicle. At the same time, a first ultrasonic radar 7 is also installed on the laser radar fixing frame 10, and the environmental information of the vehicle near the A-pillar is further obtained by the first ultrasonic radar 7. The millimeter wave radar fixing frame 2 is installed in the middle of the mounting substrate 1, and is also installed in the middle position of the front end of the vehicle. At least one millimeter wave radar 8 is installed on the millimeter wave radar fixing frame 2, and the millimeter wave radar 8 is used to detect the environmental information in front of the vehicle. At the same time, a second ultrasonic radar 3 is also installed in the middle of the mounting substrate 1, and the second ultrasonic radar 3 is used to further obtain the environmental information in front of the vehicle. After the radar bracket and radar are installed on the mounting substrate 1, they can be assembled into the vehicle as a whole, thereby forming a multi-radar integrated mounting structure. To facilitate accurate acquisition of environmental information, the millimeter wave radar 8 is installed in a horizontal state, while the laser radars 6 at both ends are at an angle of 45° to the central axis of the vehicle, and the first ultrasonic radar 7 and the second ultrasonic radar 3 are also installed in a horizontal state.

[0057] In this embodiment, at least three types of radars are integrated and installed on the same mounting substrate 1. When assembled on a vehicle, it is only necessary to install the mounting substrate 1 with the radar installed on the vehicle to complete the layout and installation of the radar. Compared with the traditional single radar connected to the vehicle by a single mounting structure, the installation efficiency is significantly improved. At the same time, the integration of the radar mounting structure is improved, the overall mounting structure is simplified, and the installation efficiency is improved.

[0058] The laser radar fixing frame 10 serves as the installation base of the laser radar 6 and the first ultrasonic radar 7. The structure of the laser radar fixing frame 10 is specifically described in this embodiment:

[0059] like Figure 3 and Figure 4 As shown, the laser radar fixing frame 10 includes a fixing frame support plate 4, a fixing frame radar cover 5 and a fixing frame bottom plate 9;

[0060] The fixing frame support plate 4 is fixed on the mounting base plate 1, the fixing frame radome 5 is fixed on the fixing frame support plate 4, and the fixing frame bottom plate 9 is fixed on the fixing frame radome 5;

[0061] The laser radar 6 is fixed on the fixing frame bottom plate 9 , and the first ultrasonic radar 7 is fixed on the fixing frame radar cover 5 .

[0062] Specifically, the fixing frame support plate 4 is fixed on the mounting base plate 1 and can be fixedly connected by bolts. The fixing frame support plate 4 can be set as a U-shaped structure, which is clamped on the mounting base plate 1 during installation and fixed to the mounting base plate 1 by bolts, which is convenient for installation and disassembly. The fixing frame radome 5 is installed on the fixing frame support plate 4 and can be fixedly connected by bolts. The fixing part base plate is installed in the fixing part radome and serves as the installation base of the laser radar 6. The fixing frame radome 5 can protect the installed laser radar 6. At the same time, the fixing frame radome 5 also directly serves as the installation base of the first ultrasonic radar 7.

[0063] like Figure 2 As shown, the fixed frame support plate 4 includes a connecting side plate 41, and a first connecting horizontal plate 42 and a second connecting horizontal plate 43 respectively arranged at the upper and lower ends of the connecting side plate 41; the connecting side plate 41 is attached to the surface of the mounting substrate 1 and is fixedly connected to the mounting substrate 1; the first connecting horizontal plate 42, the second connecting horizontal plate 43 and the connecting side plate 41 are integrally formed to form a U-shaped structure; the upper end of the fixed frame radome 5 is placed on the upper surface of the first connecting horizontal plate 42 and is fixedly connected to the first connecting horizontal plate 42, and a part of the fixed frame bottom plate 9 passes through the fixed frame radome 5 and is placed on the upper surface of the second connecting horizontal plate 43 and is fixedly connected to the second connecting horizontal plate 43. This structure can not only ensure the stability of the connection between the fixed frame radar bracket, the fixed frame bottom plate 9 and the fixed frame support plate 4, but also make the entire connection structure simpler.

[0064] The fixed frame radome 5 serves as a protective structure for the laser radar 6 and an installation basis for the first ultrasonic radar 7. To facilitate the installation of the laser radar 6 and the first ultrasonic radar 7, the present embodiment specifically describes the structure of the fixed frame radome 5:

[0065] In this embodiment, the fixed frame radar cover 5 includes an upper cover body 51, a lower cover body 52 and a connecting body 53 connected between the upper cover body 51 and the lower cover body 52; the upper cover body 51, the lower cover body 52 and the connecting body 53 are integrally formed, and the upper cover body 51 and the lower cover body 52 are coaxial cylindrical structures; the installation space 54 has an arc-shaped opening that matches the detection range of the laser radar 6. The upper cover body 51 has a first connecting portion 511 overlapped on the first connecting horizontal plate 42, and the first connecting portion 511 and the first connecting horizontal plate 42 are fixedly connected by bolts;

[0066] The fixing frame bottom plate 9 is arranged in the lower cover body 52, and the main structure of the fixing frame is circular, and its diameter matches the inner diameter of the lower cover body 52. ​​When the fixing frame bottom plate 9 is installed in the lower cover body 52, there is an installation space 54 for accommodating the laser radar 6 between the upper cover body 51 and the fixing frame bottom plate 9, and the laser radar 6 is installed in the installation space 54; the fixing frame bottom plate 9 has a second connecting portion 91, and the second connecting portion 91 passes through the side wall of the lower cover body 52 and is fixedly connected to the second connecting horizontal plate 43 by bolts; the first ultrasonic radar 7 is fixed on the lower cover body 52, and the first ultrasonic radar 7 is located below the laser radar 6.

[0067] In order to facilitate the installation of the first ultrasonic radar 7, a first installation hole is opened on the lower cover 52, and the first ultrasonic radar 7 is fixed in the first installation hole;

[0068] Since the laser radar 6 is installed on the upper surface of the fixing frame bottom plate 9, a first wiring hole 92 is provided on the fixing frame bottom plate 9 to facilitate the connection of cables. The laser radar 6 is connected through the first wiring hole 92. The first wiring hole 92 is close to the connector 53 to reduce the exposed length of the cable.

[0069] To facilitate the installation of the second laser radar 6, a second mounting hole is provided in the middle of the mounting substrate 1. The second mounting hole is located below the millimeter wave radar 8, and the second ultrasonic radar 3 is fixed in the second mounting hole.

[0070] At present, depending on the usage and type of radar, most of the existing problems are that the traditional installation method is to fix it directly on the A-pillars on both sides of the front of the vehicle and cannot achieve angle fine-tuning. The installation structure is single and not suitable for special vehicles. The fixed position installation is not convenient for debugging the vehicle-mounted radar, which affects the efficiency of radar debugging during the initial design of the unmanned vehicle and in the later maintenance, and also increases the workload of maintenance workers.

[0071] Therefore, in order to make the installation angle of the laser radar 6 adjustable, Figure 4 As shown, in this embodiment, the connection structure of the first connecting transverse plate 42 and the second connecting transverse plate 43 is further improved:

[0072] A plurality of angle adjustment holes 44 are provided on the first connecting transverse plate 42 and the second connecting transverse plate 43, and the angle adjustment holes 44 are distributed along the circumference of the bolts;

[0073] Positioning holes 55 corresponding to the angle adjustment holes 44 are provided on the first connection portion 511 and the second connection portion 91 , and a positioning pin is connected to one of the positioning holes 55 and one of the angle adjustment holes 44 .

[0074] Specifically, the distribution range of the multiple angle adjustment holes 44 can be 15°, so as to meet the fine adjustment of the laser radar 6 within the angle range. The adjustment process is to remove the positioning pin from the positioning hole 55 and the angle adjustment hole 44, loosen the connecting bolt, rotate the fixed frame radar cover 5, so that the first connecting part 511 and the second connecting part 91 are respectively rotated around the corresponding bolt axis by a certain angle, and then insert the positioning pin into the positioning hole 55 and the angle adjustment hole 44 at the angle, and finally tighten the bolt. Multiple angle adjustment holes 44 can be connected and form an arc hole together to achieve angle adjustment, or they can be used as multiple independent holes to achieve angle adjustment.

[0075] Since the vehicle will vibrate during use, when an arc-shaped hole is used to achieve angle adjustment, the laser radar 6 is prone to angle changes during vehicle driving, and the use of multiple independent holes has the problem of limited adjustable angles. Therefore, in order to avoid the angle of the laser radar 6 from changing, improve the structural stability after adjustment, and increase the adjustable angle as much as possible, in this embodiment, adjacent angle adjustment holes 44 intersect, and the line connecting the intersection points is smaller than the diameter of the angle adjustment hole 44, which can be 3 / 4 of the diameter of the angle adjustment hole 44, thereby having a larger angle adjustment range while satisfying sufficient structural stability.

[0076] The millimeter wave radar fixing frame 2 is used to install the millimeter wave radar 8. Figure 5 As shown, it includes a millimeter-wave radar fixing plate 23 and a millimeter-wave radar protective shell 22; the millimeter-wave radar fixing plate 23 is fixed on the mounting base plate 1 and can be fixedly connected by a bolt movement, the millimeter-wave radar 8 is fixed on the millimeter-wave radar fixing plate 23 and can be fixedly connected by screws, the millimeter-wave radar protective shell 22 is covered on the millimeter-wave radar 8 and fixedly connected to the millimeter-wave radar fixing plate 23, and the millimeter-wave radar protective shell 22 plays a protective role on the millimeter-wave radar 8.

[0077] like Figure 2 and Figure 5As shown, the millimeter wave radar fixing plate 23 includes a first connecting surface 234, a second connecting surface 233 and a mounting surface 232;

[0078] The mounting surface 232 is parallel to the mounting substrate 1, and the millimeter wave radar 8 is fixed on the mounting surface 232; the first connecting surface 234 is provided at both ends of the mounting surface 232 and is perpendicular to the mounting surface 232, and the second connecting surface 233 is provided on the first connecting surface 234 and is perpendicular to the first connecting surface 234;

[0079] The second connection surface 233 is fixedly connected to the mounting substrate 1 ; the millimeter wave radar protection shell 22 is disposed on the outside of the first connection surface 234 and is fixedly connected to the first connection surface 234 .

[0080] Specifically, by setting the first connecting surface 234, the second connecting surface 233 and the mounting surface 232, a certain distance is provided between the millimeter-wave radar 8 mounted on the mounting surface 232 and the mounting substrate 1, and the width of the distance is the same as the width of the first connecting surface 234, so as to facilitate heat dissipation of the millimeter-wave radar 8.

[0081] In order to facilitate the heat dissipation of the millimeter wave radar 8, a first heat dissipation hole 231 is provided on the mounting surface 232. The first heat dissipation hole 231 is provided as a vertical strip hole. The millimeter wave radar 8 overlaps with at least a portion of the first heat dissipation hole 231.

[0082] A second heat dissipation hole 24 is provided at the lower end of the millimeter wave protective shell, and the second heat dissipation hole 24 is located below the millimeter wave radar 8; the heat dissipation performance of the millimeter wave radar 8 is improved by combining the first heat dissipation hole 231 and the second heat dissipation hole 24, thereby improving the use stability.

[0083] Due to the limitation of the terminal structure of the millimeter wave radar 8, the inner wall of the millimeter wave protective shell cannot fit with the detection end of the millimeter wave radar 8, which will cause interference to the detection signal of the millimeter wave radar 8. Therefore, in order to solve this problem, a detection window 21 matching the detection range of the millimeter wave radar 8 is opened on the millimeter wave protective shell. The detection window 21 is recessed toward the millimeter wave radar 8. The detection end of the millimeter wave radar 8 corresponds to the detection window 21. The detection end of the millimeter wave radar 8 can be completely located in the detection window 21, so that the millimeter wave protective shell can protect the millimeter wave radar 8 and avoid interference with the detection end.

[0084] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Within the spirit and principle of the present application, any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present application.
