Description

Technical Field

[0001] The utility model relates to the technical field of testing tooling, in particular to a vehicle-mounted millimeter-wave radar testing tooling. Background Art

[0002] During the R&D phase, automotive millimeter-wave radars require on-vehicle verification testing, which involves installing the radar on the front of the vehicle for positioning. This positioning process involves installing the radar at different locations on the front of the vehicle and performing functional tests on the radar at various locations to determine the optimal placement.

[0003] During the existing on-board millimeter-wave radar positioning process, one method for adjusting the test position of the on-board millimeter-wave radar is to design a radar mounting bracket and fix it to the bumper of the test vehicle. Therefore, different radar mounting brackets must be designed for different test positions. Each adjustment of the test position takes a long time, and the mounting bracket is not securely attached to the front bumper of the vehicle, affecting the test results and potentially damaging the test vehicle's bumper. Another method is to temporarily install the on-board millimeter-wave radar on the vehicle using a binding or gluing method before performing functional testing. After the on-board millimeter-wave radar is tested in one position, the position of the on-board millimeter-wave radar needs to be readjusted. This means that the on-board millimeter-wave radar needs to be removed and then bound or glued to another position on the vehicle for further testing. Moreover, this temporary mounting method of binding or gluing cannot guarantee the stability of the on-board millimeter-wave radar during testing. In other words, the mounting bracket is not secure and is prone to falling during testing.

[0004] In summary, the existing positioning process for vehicle-mounted millimeter-wave radars is cumbersome, time-consuming, and labor-intensive. The installation is unstable, and the horizontal and elevation angles of installed vehicle-mounted millimeter-wave radars cannot be adjusted, which affects radar testing efficiency. Therefore, improvements are necessary. Utility Model Content

[0043] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the usual meanings understood by people with ordinary skills in the field to which the present invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Unless otherwise specified, the "connection" described in this article can be a direct connection or an indirect connection, that is, a connection through an intermediate.

[0044] like Figure 1 As shown in this example, the vehicle-mounted millimeter-wave radar test fixture of the present invention includes: a connecting member 10, an adjusting member 20, and a radar bracket 30. The adjusting member 20 can be installed on the vehicle body through the connecting member 10, so that the adjusting member 20 is installed on the vehicle body. The radar bracket 30 is used to install the vehicle-mounted millimeter-wave radar. The radar bracket 30 is detachably connected to the adjusting member 20 and can be set at any position on the adjusting member 20. In this way, the radar body 40 installed on the radar bracket 30 can be tested at any position on the adjusting member 20, thereby conveniently changing the test position of the vehicle-mounted millimeter-wave radar and improving test efficiency.

[0045] Continue as Figure 1 As shown, in this example, the connector 10 has a body-mounting end 11 and an adjusting member connecting end 12. The body-mounting end 11 is connected to the vehicle body, for example, by screws, snaps, or magnets, thereby allowing the connector 10 to be removably mounted on the vehicle body. The adjusting member connecting end 12 is removably connected to the adjusting member 20, for example, by screws, snaps, or magnets, thereby allowing the adjusting member 20 to be removably mounted on the vehicle body.

[0046] Continue as Figure 1 As shown, in this example, the adjustment member 20 has a first mounting portion 21 and a second mounting portion 22. The radar bracket 30 is detachably connected to the first mounting portion 21, such as by a threaded connection, and can be positioned at any position on the first mounting portion 21. This allows the radar body 40 mounted on the radar bracket 30 to be tested at any position on the adjustment member 20, thereby conveniently changing the test position of the vehicle-mounted millimeter-wave radar and improving testing efficiency. The second mounting portion 22 is disposed opposite the first mounting portion 21 and is used to connect to the connector 10. The second mounting portion 22 is detachably connected to the adjustment member connection end 12, thereby achieving a detachable connection between the adjustment member 20 and the connector 10.

[0047] Continue as Figure 1 As shown, in a further example, the first mounting portion 21 is provided with a plurality of mounting holes 211. The mounting holes 211 are used to mount the radar bracket 30. When the test position of the radar body 40 is to be changed, the radar bracket 30 only needs to be removed from the first mounting portion 21 and then mounted in another mounting hole 211.

[0048] In a further example, the second mounting portion 22 may not be arranged opposite to the first mounting portion 21 , as long as the second mounting portion 22 does not affect the installation of the first mounting portion 21 and the radar bracket 30 after being connected to the vehicle body.

[0049] In further examples, the adjustment member 20 may also be disc-shaped, bowl-shaped, or stick-shaped. In short, as long as the radar bracket 30 can be mounted on the adjustment member 20 at at least two different positions to adjust the test position of the radar body 40, the adjustment member 20 is not limited to a regular shape.

[0050] In a further example, the adjusting member 20 can simultaneously install multiple radar brackets 30, and the multiple radar brackets 30 can be installed with the same or different models of vehicle-mounted millimeter-wave radars to meet different testing requirements.

[0051] like Figure 1 and Figure 2 As shown, in this example, the radar bracket 30 is a universal bracket that supports multi-directional and multi-angle adjustment of the radar body 40. The radar bracket 30 includes a support frame 31, a middle frame 32, and a mounting frame 33. The support frame 31 is detachably connected to the adjustment member 20 and can be installed at any position on the adjustment member 20. Specifically, the support frame 31 is detachably connected to the first mounting portion 21 of the adjustment member 20. For example, the support frame 31 is screwed to the mounting hole 211 of the first mounting portion 21, thereby achieving a detachable connection between the radar bracket 30 and the adjustment member 20. The middle frame 32 is rotatably connected to the support frame 31 to achieve angle adjustment of the azimuth direction angle of the radar bracket 30. Taking the adjustment member 20 as a plate and the connecting member 10 installed at the license plate of a car as an example, when the connecting member 10 and the adjustment member 20 are installed at the license plate of the car in sequence, the adjustment member 20 is perpendicular to the ground, and the support frame 31 is installed on the adjustment member 20. The middle frame 32 can be rotatably connected to the support frame 31 by means of a rotating shaft or the like, and rotate around a straight line parallel to the adjustment member 20 as an axis to achieve angle adjustment of the azimuth direction angle of the radar bracket 30. The mounting bracket 33 is used to mount the vehicle-mounted millimeter-wave radar, specifically the radar body 40. The mounting bracket 33 is rotatably connected to the intermediate bracket 32 ​​to adjust the pitch angle of the radar bracket 30. Similarly, continuing with the example of a plate-shaped adjustment member 20 and a connector 10 mounted on a vehicle's license plate, the mounting bracket 33 can be rotatably connected to the intermediate bracket 32 ​​using a rotating shaft or other method, rotating about a line parallel to the horizontal plane to adjust the pitch angle of the radar bracket 30. In a more preferred embodiment, the support bracket 31 can be rotatably connected to the adjustment member 20 about a line perpendicular to the plane of the adjustment member 20, thereby adjusting the roll angle of the radar bracket 30. This rotatable connection between the support bracket 31, the intermediate bracket 32, and the mounting bracket 33 allows the installed vehicle-mounted millimeter-wave radar to be adjusted in multiple directions and angles, without being restricted to a fixed angle after installation, thereby improving testing efficiency.

[0052] Continue as Figure 1 and Figure 2As shown, in this example, the support frame 31 includes a support mainboard 311 and support ears 312. With the perpendicular to the plane on which the support mainboard 311 lies as a first axis, the support mainboard 311 and the adjustment member 20 are rotatably connected about the first axis to adjust the roll angle of the radar bracket 30, thereby adjusting the roll angle of the radar body 40. The support mainboard 311 can be installed at any position on the adjustment member 20. Specifically, the support mainboard 311 can be installed at any position on the first mounting portion 21, facilitating the replacement of the radar bracket 30 installation position and the test position of the radar body 40. The support ears 312 are provided on the support mainboard 311, and the middle frame 32 is rotatably connected to the support ears 312 to adjust the azimuth angle of the radar bracket 30.

[0053] Continue as Figure 1 and Figure 2 As shown, in this example, the middle frame 32 has a rotating main plate 321 and a rotating ear 322. The rotating main plate 321 has a first side (not shown) and a second side 323 opposite the first side. The rotating ear 322 is provided on both the first and second sides 323 of the rotating main plate 321. Continuing with the example of a plate-shaped adjustment member 20 and a connector 10 mounted on a vehicle license plate, the rotating ear 322 on the first side of the rotating main plate 321 is rotatably connected to the support ear 312 about a second axis, with any line parallel to the plane of the adjustment member 20 or the support main plate 311 being the second axis. This allows for adjustment of the azimuth angle of the radar bracket 30, and thus the azimuth angle of the radar body 40. The rotating ear 322 on the second side 323 of the rotating main plate 321 is rotatably connected to the mounting frame 33, allowing for adjustment of the pitch angle of the radar bracket 30.

[0054] Continue as Figure 1 and Figure 2 As shown, in this example, the mounting bracket 33 has a mounting mainboard 331 and a connecting ear 332. The mounting mainboard 331 is used to mount the vehicle-mounted millimeter-wave radar, that is, to mount the radar body 40; the connecting ear 332 is provided on the mounting mainboard 331. Continuing with the example of the adjustment member 20 being plate-shaped and the connecting member 10 being mounted on the license plate of the car, any line whose projection between the plane where the adjustment member 20 or the supporting mainboard 311 is located and the projection of the second axis is at a first angle (for example, 90°) is used as the third axis, and the connecting ear 332 and the rotating ear 322 provided on the second side 323 can be rotatably connected around the third axis. This is to achieve the angle adjustment of the pitch direction angle of the radar bracket 30, and then to achieve the adjustment of the pitch direction angle of the radar body 40.

[0055] In a further example, the support frame 31 is detachably connected to the adjustment member 20, and the radar body 40 can be rotatably installed on the mounting frame 33 around its own axis with the axis of the radar body 40 itself as the axis to achieve angular adjustment of the roll direction angle of the radar body 40.

[0056] In a further example, the first angle may be 30° to 90°. In a more preferred example, the first angle is 90°.

[0057] like Figure 2 As shown, in a further example, the supporting ears 312 , the rotating ears 322 and the connecting ears 332 are respectively provided at the edges of the supporting main board 311 , the rotating main board 321 and the placing main board 331 .

[0058] In a further example, scales are provided on the supporting ear 312 and the connecting ear 332 to achieve the accuracy of the angle adjustment of the radar body 40 and the recording of the angle adjustment data.

[0059] In a further example, the radar bracket 30 can also be used to install equipment such as a laser radar, a camera, or a locator, and play the role of the corresponding equipment.

[0060] In summary, the present invention provides an adjustment member 20 and a radar bracket 30. The adjustment member 20 is mounted on the vehicle body, and the radar bracket 30 can be set at any position on the adjustment member 20. The vehicle-mounted millimeter-wave radar to be tested is then mounted on the radar bracket 30, thereby conveniently changing the test position of the vehicle-mounted millimeter-wave radar, thereby improving testing efficiency. In addition, the present invention also uses a rotating connection between the support frame 31, the middle frame 32, and the placement frame 33 to enable the installed vehicle-mounted millimeter-wave radar to be adjusted in multiple directions and angles, without being restricted to a fixed angle after installation, thereby improving testing efficiency.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
