Description

Technical Field

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

[0002] The vehicle-mounted millimeter-wave radar needs to be verified and tested on a real vehicle during the R&D stage, and the radar needs to be installed on the front of the vehicle for positioning. The positioning process is to install the radar at different positions on the front of the vehicle, and perform functional tests on the radar when it is located at different positions on the vehicle to find the best position for the radar to be installed on the vehicle.

[0003] In the existing on-board millimeter-wave radar positioning process, one way to adjust the test position of the on-board millimeter-wave radar is to design a radar mounting bracket to be fixed on the bumper of the test vehicle. Therefore, different radar mounting brackets should be designed for different test positions. Each adjustment of the test position takes a long period of time, and the installation on the front bumper of the vehicle body is not firm, which affects the test effect and may damage the bumper of the test vehicle. Another way is to temporarily install the on-board millimeter-wave radar on the vehicle by bundling or pasting before performing a functional test. After the test of the on-board millimeter-wave radar at one position is completed, the position of the on-board millimeter-wave radar needs to be readjusted, that is, the on-board millimeter-wave radar is removed, and it is bundled or pasted to other positions of the vehicle for testing. Moreover, the temporary installation method of bundling or pasting cannot guarantee the stability of the on-board millimeter-wave radar during the test process, that is, the installation is not firm and it is easy to fall during the test.

[0004] In summary, the existing vehicle-mounted millimeter-wave radar positioning process is very cumbersome, time-consuming and labor-intensive, and the installation is not firm. In addition, the installed vehicle-mounted millimeter-wave radar cannot be adjusted in horizontal and elevation angles, which affects the radar test efficiency.

[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 car body through the connecting member 10, so that the adjusting member 20 is installed on the car 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 of 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 realizing the convenient replacement of the test position of the vehicle-mounted millimeter-wave radar, thereby improving the test efficiency.

[0045] Continue as Figure 1As shown, in this example, the connector 10 has a body mounting end 11 and an adjustment member connecting end 12. The body mounting end 11 is connected to the vehicle body, for example, the body mounting end 11 is connected to the vehicle body by means of screws, buckles or magnets, so that the connector 10 is detachably mounted on the vehicle body. The adjustment member connecting end 12 is detachably connected to the adjustment member 20, for example, the adjustment member connecting end 12 can be connected to the adjustment member 20 by means of screws, buckles or magnets, so that the adjustment member 20 is detachably mounted on the vehicle body.

[0046] Continue as Figure 1 As shown, in this example, the adjusting 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 threaded connection, and the radar bracket 30 can be arranged at any position of the first mounting portion 21, so that the radar body 40 mounted on the radar bracket 30 can be tested at any position on the adjusting member 20, thereby realizing convenient replacement of the test position of the vehicle-mounted millimeter-wave radar, thereby improving the test efficiency.
