[0034] The utility model provides a bracket for radar testing.

[0035] Reference Figures 1 to 4 , Figure 1 This is a schematic structural diagram of an embodiment of the radar test bracket of the utility model; Figure 2 This is a schematic structural diagram of another embodiment of the radar testing bracket of the utility model; Figure 3 This is a schematic structural diagram of another embodiment of the radar test bracket of the utility model; Figure 4 for Figure 1 A partial enlarged view of point A in the middle.

[0036] In the embodiment of the present utility model, the radar test bracket 1000; Figures 1 to 4 As shown, including:

[0037] A base 10, wherein the base 10 is provided with a support group 20;

[0038] A fixing device, the fixing device is connected to the supporting group 20 via a moving structure 30;

[0039] The fixing device is movably connected to the movable structure 30 , and the fixing device carries the test hardware.

[0040] It can be understood that the base 10 serves as a supporting base of the bracket 1000 , providing a stable detection platform for the test of the bracket 1000 , which is conducive to ensuring the smooth progress of the test of the ultrasonic radar.

[0041] like Figures 1 to 3 As shown, the base 10 is a rectangular structure, and the base 10 includes two first support rods 11 and two second support rods 12. The two first support rods 11 and the two second support rods 12 are arranged at intervals and connected end to end. The lengths of the first support rods 11 and the second support rods 12 are adjustable.

[0042] It can be understood that the length of the first support rod 11 ranges from 1200 mm to 1800 mm, and the length of the second support rod 12 ranges from 0 mm to 500 mm.

[0043] It is understandable that the length range of the first support rod 11 and the second support rod 12 is limited so that the frame size of the base 10 can conform to the outer frame size of different vehicle models, improve the matching degree of the outer frame size of the bracket and the physical test vehicle, and improve the accuracy of the test.

[0044] It can be understood that the fixing device is used to carry the test hardware and is installed on the support group 20 through the mobile structure 30 to simulate the loading of the test hardware on the physical experimental vehicle to fit the test scenario of the actual vehicle test hardware and ensure the accuracy of the test.

[0045] It should be noted that the fixing device can be a clamp to clamp the test hardware, and the clamp is movably connected to the mobile structure 40 to facilitate the rotation of the fixing device relative to the mobile structure 40, providing the fixing device with more degrees of freedom to facilitate the position adjustment of the test hardware, so that in the process of simulating the physical test vehicle through the bracket, the position of the test hardware fits the position on the physical vehicle, which is conducive to improving the accuracy and quality of the test.

[0046] It should be noted that the test hardware is ultrasonic radar hardware.

[0047] like Figures 1 to 4 As shown, the movable structure 30 is used to realize the movement of the fixture on the support group 20, providing the fixture and the test hardware with more degrees of freedom, so as to adjust the relative position between the fixture and the base 10, thereby meeting the assembly test requirements of the test hardware.

[0048] It should be noted that when testing the test hardware, the number of hardware can be multiple, support groups 20, and multiple support groups are distributed on the surface of the base 10 at intervals according to the test requirements. Each support group is provided with a mobile structure 30, and the mobile structures 30 are movably connected with a fixing device to facilitate the connection of different test hardware to achieve the purpose of combined testing and improve the diversity and accuracy of the test.

[0049] like Figures 1 to 3 As shown, there are four support groups 20, which are distributed at different positions on the surface of the base 10 to simulate different installation positions of four test hardware in a physical experimental vehicle to meet the development and testing functions of ultrasonic wave receiving and transmitting and ranging.

[0050] It should be noted that when it is necessary to perform ultrasonic radar tests on the front and rear of a vehicle simultaneously, two sets of the brackets 1000 can be selected.

[0051] The technical solution of the utility model is to set a base 10 and a support group 20, and load test hardware on the support group 20 to simulate the scenario of testing related functions and tuning work of a physical experimental vehicle loaded with test hardware, so as to avoid affecting the testing progress and efficiency of the test hardware on the physical experimental vehicle due to the lack of the physical experimental vehicle, and improve the quality and efficiency of the test. By setting a mobile structure 30 and a fixing device movably connected to the mobile structure 30, the test hardware can be given multiple degrees of freedom to meet the test hardware installation requirements of various vehicle models, improve the matching degree with the test scenario of the physical experimental vehicle, and then improve the efficiency and quality of the test.

[0052] In order to facilitate the movement and adjustment of the fixing device on the support group 20 , the moving structure 30 is connected to the surface of the support group 20 facing away from the base 10 , and the fixing device is away from the support group 20 .

[0053] It can be understood that the setting of the support group 20 sets the fixing device away from the base 10, and cooperates with the mobile structure 30 to adjust the movement of the fixing device on the support group 20, so as to simulate the position of the test hardware in the physical experimental vehicle. Then, when performing functional testing and performance tuning on the test hardware, it is possible to accurately test the corresponding data in accordance with the actual scenario, reduce the dependence on the physical experimental vehicle during the test hardware testing process, so as to identify development risks in advance and improve development efficiency.

[0054] like Figures 1 to 3 As shown, the support group 20 is a rod-shaped or column-shaped structure, which is used to support the mobile structure 30 so that the mobile structure 30 is away from the base 10, and further the fixing device is away from the base 10.

[0055] It is understandable that the support group 20 is disposed on the surface of the base 10 , and can achieve preliminary positioning of the test hardware relative to the base 10 in the X-axis and Y-axis directions.

[0056] In order to achieve the position movement adjustment of the test hardware, the mobile structure 30 includes a mobile unit and a mobile platform; the mobile platform 34 is connected to the support group 20, the mobile unit is arranged on the surface of the mobile platform 34 away from the support group 20, and the fixing device is movably connected to the mobile unit.

[0057] It can be understood that the mobile platform 34 is connected to the surface of the support group 20 away from the base 10, and the mobile platform 34 is parallel to the base 10, so that the fixing device located on the surface of the mobile platform 34 can move in the horizontal plane when being driven to move, thereby avoiding position adjustment errors of the mobile fixing device on the mobile platform 34, which affects the accuracy of the installation of the test hardware relative to the actual installation position of the physical experimental vehicle, which is beneficial to ensure the accuracy of subsequent detection.

[0058] It can be understood that the setting of the mobile unit facilitates the movement control of the fixing device on the mobile platform 34, so as to facilitate the fine adjustment of the position of the fixing device and the test hardware, so that the position of the test hardware on the bracket 1000 can be more consistent with the position of the test hardware on the physical experimental vehicle, so as to ensure the accuracy of the measurement of the test hardware and the test efficiency after the bracket 1000 replaces the physical experimental vehicle.

[0059] It should be noted that the moving unit realizes displacement adjustment in a single direction. In order to realize multi-directional adjustment of the fixing device, multiple moving units can be arranged on the moving platform 34, thereby realizing precise adjustment of the position of the fixing device.

[0060] like Figures 1 to 4 As shown, three mobile units are provided for respectively realizing position adjustment of the fixing device in three directions of X-axis, Y-axis and Z-axis, so that the test hardware has freedom of movement in three directions of X-axis, Y-axis and Z-axis. The three mobile units are connected to each other in pairs, and one mobile unit is movably connected to the fixing device, so that the test hardware has more degrees of freedom and meets the installation requirements of various types of test hardware.

[0061] In order to realize multi-directional position adjustment of the test hardware, the mobile unit includes a first mobile unit 31, a second mobile unit 32 and a third mobile unit 33; the first mobile unit 31 is fixed on the surface of the mobile platform 34, the second mobile unit 32 is slidably arranged on the first mobile unit 31, and the third mobile unit 33 is slidably arranged on the second mobile unit 32; the part of the third mobile unit 33 away from the mobile platform 34 is movably connected to the fixing device.

[0062] like Figures 1 to 3 As shown, the first moving unit 31 is used to realize the movement of the second moving unit 32 in the X-axis direction, the second moving unit 32 is used to realize the movement of the third moving unit 33 in the Y-axis direction, and the third moving unit 33 realizes the movement of the fixing device in the Z-axis direction.

[0063] It can be understood that by driving the second mobile unit 32, the third mobile unit 33 and the fixing device to move respectively, the fixing device can be adjusted in three directions of X, Y and Z axes so that the test hardware can meet its installation requirements.

[0064] It should be noted that in order to ensure the stability of the second mobile unit 32 moving on the first mobile unit 31, there are multiple first mobile units 31, and the multiple first mobile units 31 are distributed at intervals, and the second mobile unit 32 is erected between the multiple first mobile units 31 to support the second mobile unit 32.

[0065] like Figure 1 As shown, there are two first mobile units 31, the two first mobile units 31 are arranged at an interval, and the two first mobile units 31 are both arranged on the side of the mobile platform, and the second mobile unit 32 is erected between the two first mobile units 31, so that the second mobile unit 32 can move on the first mobile unit 31, and the second mobile unit 32 is stably supported by the two first mobile units 31 to ensure the stability of movement.

[0066] In order to ensure the accuracy of the movement of the fixing device, the second moving unit 32 is arranged perpendicular to the first moving unit 31 , the third moving unit 33 is arranged perpendicular to the second moving unit 32 , and the third moving unit 33 is arranged perpendicular to the first moving unit 31 .

[0067] It is understandable that if Figure 1 As shown, the first mobile unit 31 and the second mobile unit 32 are arranged perpendicular to each other, the third mobile unit 33 and the second mobile unit 32 are arranged perpendicular to each other, and the first mobile unit 31 and the third mobile unit 33 are arranged perpendicular to each other, so that when the fixing device is moved by the mobile unit, it can accurately move in the three directions of X-axis, Y-axis and Z-axis, so that the fixing device and the test hardware can be accurately positioned and moved, ensuring the accuracy of the installation position of the test hardware and improving the efficiency and accuracy of the test hardware.

[0068] In order to facilitate the movement of the second mobile unit 32 on the first mobile unit 31, the first mobile unit 31 includes a first support member 311 and a first slide bar 312. The first support member 311 is fixed on the surface of the mobile platform 34, the first slide bar 312 is connected to the side of the first support member 311, and the second mobile unit 32 is arranged through the first slide bar 312.

[0069] like Figure 4 As shown, the first slide bar 312 passes through the second movable unit 32, so that the second movable unit 32 can move on the first slide bar 312, so as to realize the movement of the second movable unit 32, the third movable unit 33 and the fixing device in the X-axis direction.

[0070] In order to ensure the stability of the installation of the first slide bar 312, two first support members 311 are provided, and the two ends of the first slide bar 312 are respectively connected to the two first support members 311 to achieve stable support for the first slide bar 312, thereby preventing the first slide bar 312 from tilting when the second mobile unit 32 moves on the first slide bar 312 and affecting the accuracy of the movement of the second mobile unit 32.

[0071] To facilitate the movement of the third mobile unit 33, the second mobile unit 32 includes a second support member 322 and a second slide bar 321. The first slide bar 312 passes through the second support member 322. The second slide bar 321 is connected to the side of the second support member 322. The second slide bar 321 passes through the third mobile unit 33.

[0072] It can be understood that the second sliding bar 321 passes through the third moving unit 33 , and the third moving unit 33 can move along the second sliding bar 321 .

[0073] In order to ensure the stability of the second slide bar 321 , there are two second support members 322 , and the second slide bar 321 is connected between the two second support members 322 to avoid affecting the stability of the movement of the third moving unit 33 due to one end of the second slide bar 321 being suspended in the air.

[0074] It should be noted that two first movable units 31 are provided, and the two second support members 322 are respectively penetrated by the two first sliding rods 312, so that the second movable unit 32 is supported by the two first movable units 31, so that the second movable unit 32 can remain stable when moving.

[0075] In order to realize the movement of the fixing device in the Z-axis direction, the third moving unit 33 includes a third support member 331 and a telescopic rod 332, the second sliding rod 321 is passed through the third support member 331, the telescopic rod 332 is connected to the side of the third support member 331 away from the mobile platform 34, and the fixing device is movably connected to one end of the telescopic rod 332.

[0076] It can be understood that the second sliding rod 321 passes through the third supporting member 331 , so that the third supporting member 331 can move along the second sliding rod 321 to achieve movement of the third moving unit 33 on the Y axis.

[0077] It is understandable that the telescopic rod 332 is connected to the side of the third support member 331 away from the movable platform 34, and the fixing device is moved away from or close to the second sliding rod 321 by means of telescopic rod 332, so as to realize the movement of the fixing device in the Z-axis direction.

[0078] It is understandable that one end of the telescopic rod 332 is movably connected to the fixing device, so that the fixing device can rotate around the Z axis, Y axis or X axis, so that the fixing device has rotational freedom, which facilitates the test hardware to meet the installation requirements on various vehicle models.

[0079] In order to increase the moving distance of the second moving unit 32 on the moving platform 34 , the first moving unit 31 is disposed on a side of the moving platform 34 away from the surface of the base 10 .

[0080] It can be understood that the first mobile unit 31 is arranged on the side of the mobile platform 34 so that the distance between the first mobile unit 31 and the side of the mobile platform 34 away from the first mobile unit 31 is maximized, so as to provide the second mobile unit 32 with a longer moving path, so as to better adjust the position of the fixture and the test hardware.

[0081] Optionally, the distance between the mobile platform 34 and the plane of the base 10 facing away from the mobile platform 34 is 300 mm.

[0082] It is understandable that the distance between the mobile platform 34 and the ground of the base 10 is 300 mm, so that the bracket 1000 can meet the fixed height requirements of large, medium and small passenger cars.

[0083] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
