Description

Technical Field

[0001] This utility model relates to the field of radar testing technology, and in particular to a radar installation testing device. Background Technology

[0002] Millimeter-wave radar (hereinafter referred to as "radar") is a radar system that uses the millimeter-wave band for detection. It is typically installed throughout a vehicle. Taking the front bumper as an example, if the radar is installed in the center of the front bumper, it usually provides a wider detection range, but this is limited by the front design of different vehicle models. For example, the style of the radiator grille can affect the radar's detection performance. If installed on the sides of the front bumper, it can assist with lane changing, but the detection range is smaller than that of the center position. In other words, different vehicle designs of different models will affect the radar's detection performance.

[0003] Therefore, in practice, multiple tests are required based on the vehicle model design and the manufacturer's estimated installation location to analyze the radar detection performance at different installation positions. Currently, however, this is typically done manually based on past experience, with the radar manually installed at each manually determined location, and radar performance evaluated using host computer software. This experience-based method is inaccurate, prone to misjudgments, and increases the number of installations and tests, reducing testing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of low accuracy in vehicle installation testing of existing millimeter-wave radar. This invention provides a radar installation testing device that can flexibly adjust the installation position of the millimeter-wave radar relative to the vehicle, achieving high accuracy, reducing the likelihood of misjudgment, and providing high installation and testing efficiency.

[0005] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a radar installation testing device, comprising:

[0006] A first drive unit extends along a first direction and is used to connect to a vehicle;

[0007] A second driving unit extends along a second direction and is slidably connected to a first driving unit along a first direction. The first driving unit is used to drive the second driving unit to slide along the first direction.

[0008] An angle adjustment component is used to mount a radar and to adjust the attitude angle of the radar in the first direction, the second direction, and the third direction. The angle adjustment component is slidably connected to the second drive unit in the second direction, and the second drive unit is used to drive the angle adjustment component to slide in the second direction. The first direction, the second direction, and the third direction are orthogonal to each other, and the second direction is parallel to the height direction of the vehicle.

[0009] A host computer is used to electrically connect to the radar mounted on the angle adjustment component.

[0010] Using the above technical solution, the radar installation testing device of this application embodiment can semi-automatically adjust the installation position of the radar (e.g., millimeter-wave radar) relative to the vehicle in the first and second directions. Furthermore, it can also adjust the attitude angle of the radar in the first direction (e.g., parallel to the width direction of the vehicle), the second direction (e.g., parallel to the height direction of the vehicle), and the third direction (e.g., parallel to the length direction of the vehicle), thereby realizing all-round adjustment of the radar installation position. The device can also detect the radar detection performance under different installation positions through a host computer, so as to visualize and digitize the performance data.

[0011] Specifically, a first drive unit extending along a first direction is mounted on the vehicle. A second drive unit extending along a second direction is slidably connected to the first drive unit in the first direction. An angle adjustment member is then slidably connected to the second drive unit in the second direction, and the radar is mounted on the angle adjustment member. In this structural design, the angle adjustment member can be driven to slide along the second direction via the second drive unit, while the second drive unit and the angle adjustment member thereon can be driven to slide along the first direction via the first drive unit. This achieves radar position adjustment relative to the vehicle in both the first and second directions with a relatively simple structure and lower cost.

[0012] At the same time, the angle adjustment component can also adjust the radar's attitude angles in various directions (such as roll angle, yaw angle and pitch angle as described below). By changing the attitude angles, it can simulate various angles and positions that the radar may have in actual applications, making the radar performance test more comprehensive and facilitating a comprehensive evaluation of the radar performance, thereby ensuring the accuracy and reliability of the radar.

[0013] According to another specific embodiment of the present invention, it further includes: a mounting bracket, the mounting bracket being used for mounting to the vehicle, and the first drive unit being connected to the mounting bracket.

[0014] According to another specific embodiment of the present invention, the first driving part includes a first handle, a first guide rail, a first slider, and a first nut, wherein the outer wall of the first guide rail is provided with threads, wherein:

[0015] The first handle is connected to the first guide rail, the first nut is sleeved on the outside of the first guide rail and threaded with the first guide rail, the first nut is fixed inside the first slider, and the second drive unit is connected to the first slider;

[0016] The first handle is used to drive the first guide rail to rotate, thereby driving the first nut and the first slider to move in the first direction, so that the second driving part moves in the first direction.

[0017] According to another specific embodiment of the present invention, the first guide rail has a scale.

[0018] According to another specific embodiment of the present invention, the second driving part includes a second handle, a second guide rail, a second slider, and a second nut. The outer wall of the second guide rail is provided with threads, wherein:

[0019] The second handle is connected to the second guide rail, the second nut is sleeved on the outside of the second guide rail and threaded into the second guide rail, the second nut is fixed inside the second slider, and the angle adjustment component is connected to the second slider;

[0020] The second handle is used to drive the second guide rail to rotate, thereby driving the second nut and the second slider to move in the second direction, so that the angle adjustment member moves in the second direction.

[0021] According to another specific embodiment of the present invention, the angle adjusting component includes an angle adjusting body and an adapter connected together, the adapter having a connection port; the second driving part includes a second handle, a second guide rail, and a second nut, the outer wall of the second guide rail being threaded; wherein:

[0022] The second handle is connected to the second guide rail, the second nut is sleeved on the outside of the second guide rail and threadedly engaged with the second guide rail, and the connecting port of the adapter is fixed to the second nut;

[0023] The second handle is used to drive the second guide rail to rotate, thereby driving the second nut and the adapter to move in the second direction, so that the angle adjustment member moves in the second direction.

[0024] According to another specific embodiment of the present invention, the second guide rail has a scale.

[0025] According to another specific embodiment of the present invention, the angle adjustment component includes a gimbal.

[0026] According to another specific embodiment of the present invention, the gimbal is used to adjust the roll angle of the radar in the first direction, the yaw angle in the second direction, and the pitch angle in the third direction.

[0027] By adopting the above technical solution, the gimbal can adjust the roll angle, yaw angle and pitch angle of the radar. By changing the attitude angle, it can simulate various angles and positions that the radar may have in actual applications, making the radar performance test more comprehensive and facilitating a comprehensive evaluation of the radar performance, thereby ensuring the accuracy and reliability of the radar.

[0028] Specifically, adjusting the roll angle can test the radar performance when the vehicle body is tilted (e.g., when encountering sharp turns or crosswinds), adjusting the yaw angle can test the radar's detection range when turning or changing lanes, and adjusting the pitch angle can test the radar's detection performance at different heights (e.g., when going up or down slopes or passing speed bumps).

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0041] refer to Figure 1 and Figure 2This application provides a radar installation testing device 100, which includes a first drive unit 110, a second drive unit 120, an angle adjustment component 130, and a host computer 140.

[0042] As can be seen, the first drive unit 110 is along the first direction (e.g. Figure 1 Extending in the X direction (as shown), the first drive unit 110 is used to connect to the vehicle 200. For example, as... Figure 1 As shown, the first drive unit 110 can be connected to the front bumper 201 of the vehicle 200. The first drive unit 110, which extends in the first direction, can cover the front bumper 201 so that the millimeter-wave radar 300 can slide along the entire front bumper 201 in the first direction.

[0043] Although Figure 1 The first drive unit 110 shown is installed at the position of the front bumper 201, but this embodiment does not specifically limit it. For example, it can also be connected to the rear bumper or other positions, and can be adapted according to actual application needs or vehicle design.

[0044] Meanwhile, the aforementioned second drive unit 120 moves along the second direction (e.g. Figure 1 and Figure 2 Extending in the Z direction (as shown in the diagram), the second drive unit 120 is slidably connected to the first drive unit 110 in a first direction, and the first drive unit 110 is capable of driving the second drive unit 120 along the first direction (e.g., the Z direction shown in the diagram). Figure 1 Slide in the X direction (as shown in the diagram).

[0045] Furthermore, the aforementioned angle adjustment component 130 (e.g., gimbal 131) is used to mount a radar (e.g., millimeter-wave radar 300) and is capable of adjusting the millimeter-wave radar 300 in a first direction (e.g., Figure 1 The X direction shown in the figure), the second direction (such as...) Figure 1 and Figure 2 The Z direction shown in the figure) and the third direction (such as Figure 2 The attitude angle in the Y direction is shown in the figure.

[0046] It should be noted that in this embodiment, the first direction, the second direction, and the third direction are orthogonal to each other, and the second direction is parallel to the height direction of the vehicle 200.

[0047] Furthermore, the gimbal 131 in this embodiment of the application can also be used along a second direction (such as... Figure 1 and Figure 2 The gimbal 131 is connected to the second drive unit 120 in a slidable manner (Z direction shown in the diagram), and the second drive unit 120 is capable of driving the gimbal 131 to slide along the second direction.

[0048] In other words, the radar installation testing device 100 of this application embodiment can flexibly adjust the installation position of the millimeter-wave radar 300 relative to the vehicle 200 using only the first drive unit 110, the second drive unit 120, and the gimbal 131. Based on this, the millimeter-wave radar 300 is electrically connected to the host computer 140. Each time the installation position of the millimeter-wave radar 300 is changed, the host computer 140 analyzes and evaluates the detection performance of the millimeter-wave radar 300 at that installation position, thereby obtaining an assessment of the impact of different installation positions on the detection performance of the millimeter-wave radar 300. Visualized and quantified performance test data can also be obtained through the host computer 140.

[0049] Using the above technical solution, the millimeter-wave radar 300 installation testing device 100 of this application embodiment can semi-automatically adjust the installation position of the millimeter-wave radar 300 relative to the vehicle in the first direction and the second direction. Furthermore, it can also adjust the attitude angle of the millimeter-wave radar 300 in the first direction (e.g., parallel to the width direction of the vehicle), the second direction (e.g., parallel to the height direction of the vehicle), and the third direction (e.g., parallel to the length direction of the vehicle), thereby realizing all-round adjustment of the installation position of the millimeter-wave radar 300. The host computer 140 detects the detection performance of the millimeter-wave radar 300 under different installation positions and visualizes and digitizes the performance data.

[0050] Specifically, a first drive unit 110 extending along a first direction is mounted on the vehicle. A second drive unit 120 extending along a second direction is slidably connected to the first drive unit 110 in the first direction. A gimbal 131 is then slidably connected to the second drive unit 120 in the second direction, and the millimeter-wave radar 300 is mounted on the gimbal 131. In this structural design, the gimbal 131 can be driven to slide along the second direction via the second drive unit 120, while the second drive unit 120 and the gimbal 131 can be driven to slide along the first direction via the first drive unit 110. This allows for relatively simple structure-based adjustment of the millimeter-wave radar 300 relative to the vehicle in both the first and second directions, and also reduces installation costs, effectively lowering overall expenses.

[0051] Meanwhile, the gimbal 131 can also adjust the attitude angles of the millimeter-wave radar 300 in various directions (such as the roll angle, yaw angle, and pitch angle mentioned later). By changing the attitude angles, it can simulate various angles and positions that the millimeter-wave radar 300 may have in actual applications, making the performance test of the millimeter-wave radar 300 more comprehensive and facilitating a comprehensive evaluation of the performance of the millimeter-wave radar 300, thereby ensuring the accuracy and reliability of the millimeter-wave radar 300.

[0052] refer to Figure 2In some possible implementations, the radar installation testing device 100 of this application embodiment further includes: a mounting bracket 150, which, exemplarily, is used to install to the front bumper 201 of the vehicle 200, that is, the first drive unit 110 is connected to the front bumper 201 through the mounting bracket 150.

[0053] For example, the mounting bracket 150 has a plurality of threaded holes (not shown in the figure) that correspond one-to-one with the holes (not shown in the figure) of the front bumper 201, and the mounting bracket 150 is fixed to the front bumper 201 with bolts.

[0054] For example, when the front bumper 201 of the vehicle 200 is made of metal, a magnet can also be used to attach the mounting bracket 150 to the front bumper 201 of the vehicle 200.

[0055] For example, the mounting bracket 150 can also be inserted through the front bumper 201 and connected to the anti-collision beam (not shown) on the rear side of the front bumper 201.

[0056] This application does not impose specific limitations on the structure of the mounting bracket 150. Any mounting bracket 150 that can install the first drive unit 110 onto the vehicle 200 is within the protection scope of this application.

[0057] As mentioned above, the first drive unit 110 can drive the second drive unit 120 to slide along the first direction, and the second drive unit 120 can drive the gimbal 131 to slide along the second direction.

[0058] It should be noted that the first driving unit 110 and the second driving unit 120 in this application embodiment have the same structure and driving principle, and the specific structure and driving principle of the second driving unit 120 can be referred to the first driving unit 110.

[0059] refer to Figure 3 and combined Figure 1 and Figure 2 In some possible implementations, the first drive unit 110 includes a first handle 111, a first guide rail 112, a first slider 113 and a first nut 114, and the outer wall of the first guide rail 112 is provided with threads.

[0060] like Figure 3 As shown, the first guide rail 112 is along the first direction (e.g. Figure 3 Extending in the X direction (as shown), the first handle 111 and the first guide rail 112 are rotatably connected. The first nut 114 is sleeved on the outside of the first guide rail 112 and threadedly engaged with it. The first nut 114 is fixed inside the first slider 113, as shown. Figure 2 As shown, the second drive unit 120 is connected to the first slider 113.

[0061] On the other hand, the first drive unit 110 also includes a first direction (such as...) Figure 3 The first housing 115 extends in the X direction shown in the figure. The first housing 115 is used to connect with the mounting bracket 150 mentioned above (e.g., by snap-fit, adhesive, etc.). The first housing 115 is also used to support the first handle 111, the first guide rail 112 and the first slider 113.

[0062] For example, the first housing 115 includes a first portion 1151 and a second portion 1152 connected together, the first portion 1151 being along a first direction (e.g., Figure 3 The first guide rail 112 extends in the X direction (as shown in the diagram) and connects to the mounting bracket 150; the second part 1152 is located on both sides of the first part 1151. It can be seen that the two ends of the first guide rail 112 are rotatably connected to the second parts 1152 on both sides, and extend in a third direction (such as...). Figure 3 (As shown in the Y direction), the first guide rail 112 and the first part 1151 are spaced apart; at the same time, the first handle 111 passes through the second part 1152 on one side and is rotatably connected to the first guide rail 112.

[0063] Based on this, the tester can rotate the first handle 111 to drive the first guide rail 112 to rotate (e.g. Figure 3 If the first guide rail 112 rotates in the first direction (as shown in the diagram, in the R direction), then the first nut 114 and the first slider 113 can drive the first nut 114 and the first slider 113 along the first direction (as shown in the diagram, in the R direction). Figure 3 The second drive unit 120, connected to the first slider 113, moves in the first direction (as shown in the X direction) so that it can move in the first direction (as shown in the X direction) to enable the second drive unit 120 to move in the first direction (as shown in the X direction) ... Figure 1 (Motion in the X direction shown in the figure).

[0064] refer to Figure 4 and combined Figure 1 and Figure 2 Similarly, in some possible implementations, the second drive unit 120 includes a second handle 121, a second guide rail 122, and a second slider 123 (e.g., Figure 2 As shown in the figure, the second handle 121 is connected to the second guide rail 122, the second nut 124 is sleeved on the outside of the second guide rail 122 and threadedly engaged with the second guide rail 122, the second nut 124 is fixed inside the second slider 123, and the gimbal 131 is connected to the second slider 123.

[0065] like Figure 4 As shown, the second guide rail 122 is along the second direction (e.g.) Figure 4Extending in the Z direction (as shown), the second handle 121 is rotatably connected to the second guide rail 122. The second nut 124 is sleeved on the outside of the second guide rail 122 and threadedly engaged with it. The second nut 124 is fixed inside the second slider 123, as shown. Figure 2 As shown, the gimbal 131 is connected to the second slider 123.

[0066] On the other hand, the second drive unit 120 also includes a second drive unit along the second direction (e.g. Figure 4 The second housing 125 extends in the Z direction as shown in the figure. The second housing 125 is used to connect with the second slider 123 mentioned above, and the second housing 125 is also used to carry the second handle 121, the second guide rail 122 and the second slider 123.

[0067] For example, the second housing 125 includes a third portion 1251 and a fourth portion 1252 connected to each other, the third portion 1251 being along a second direction (e.g., Figure 4 The second guide rail 122 extends along the Z direction (as shown in the diagram) and connects to the second slider 123 mentioned above; the fourth part 1252 is located on both sides of the third part 1251. It can be seen that the two ends of the second guide rail 122 are rotatably connected to the fourth parts 1252 on both sides, and extend along the third direction (as shown in the diagram). Figure 4 (As shown in the Y direction), the second guide rail 122 and the third part 1251 are spaced apart; at the same time, the second handle 121 passes through the fourth part 1252 on one side and is rotatably connected to the second guide rail 122.

[0068] Similarly, the tester can rotate the second handle 121 to drive the second guide rail 122 to rotate, and the rotating second guide rail 122 can drive the second nut 124 and the second slider 123 along the second direction (e.g., Figure 1 and Figure 2 The device moves in the Z direction (as shown in the diagram) to make the gimbal 131 and the millimeter-wave radar 300 on it move in the second direction.

[0069] In other possible implementations, the gimbal 131 can also be connected to the second drive unit 120 in other ways. Specifically, the gimbal 131 includes a connected gimbal body and an adapter (not shown in the figure). It is understood that the adapter is a connector that connects the gimbal 131 to other devices. It includes a connection port suitable for the second drive unit 120. The connection port of the adapter can be directly fixed to the second nut 124 in the second drive unit 120, and the connection port is threadedly engaged with the second nut 124. Based on this, the second slider 123 mentioned above is no longer used.

[0070] In other words, the tester can rotate the second handle 121 to drive the second guide rail 122 to rotate, and the rotating second guide rail 122 can directly drive the adapter and its gimbal 131 along the second direction (e.g., Figure 1 (The motion is shown in the Z direction).

[0071] refer to Figures 3 to 5 In some possible implementations, including embodiments of this application, the first drive unit 110 and the second drive unit 120 also have scales. The first drive unit 110 will be used as an example for explanation.

[0072] Specifically, in the first drive unit 110, the first portion 1151 of the first housing 115 is provided with a direction along the first direction (e.g., Figure 5 The scale 1150 (shown in the X direction) is spaced apart. When the first slider 113 slides along the first direction, the sliding distance of the first slider 113 can be located and read by observing the scale 1150, so that the sliding distance of the second drive unit 120 relative to the first drive unit 110 is more accurate, and the test accuracy of the radar mounting test device 100 is further improved.

[0073] Similarly, in the second drive unit 120, the third portion 1251 of the second housing 125 is provided with a direction along the second direction (e.g., Figure 4 The scale is spaced at intervals in the Z direction shown in the figure. When the second slider 123 (or the adapter of the gimbal 131) slides in the second direction, the sliding distance of the second slider 123 (or the adapter of the gimbal 131) can be located and read by observing the scale, so that the sliding distance of the gimbal 131 relative to the second drive unit 120 is more accurate, and the test accuracy of the radar installation test device 100 is further improved.

[0074] refer to Figure 6 and combined Figure 1 and Figure 2 In some possible implementations, the gimbal 131 includes a base 1311, a roll axis 1312, a yaw axis 1313, and a pitch axis 1314 connected together.

[0075] Among them, the base 1311 and the aforementioned second slider 123 (as shown) Figure 4 (As shown) Connection, for example, the base 1311 can be fixed to the second slider 123 by means of adhesive, snap-fit, etc. (as shown) Figure 4 (as shown); or, the base 1311 is connected to the aforementioned adapter, that is, the gimbal 131 has a suitable adapter, which can be snapped or screwed into the adapter. The millimeter-wave radar 300 is mounted on the yaw axis 1313.

[0076] The yaw axis 1313 is a rotation axis that can rotate circumferentially so that the millimeter-wave radar 300 on it rotates around a second direction (e.g., Figure 6 The Z-direction shown in the figure is rotated to adjust the yaw angle.

[0077] The bottom of the roll axis 1312 and the pitch axis 1314 are provided with slide rails 1316, so that the roll axis 1312 can rotate around a first direction (e.g., Figure 6 The pitch axis 1314 can rotate left and right in the X direction (as shown in the figure) to adjust the roll angle; the pitch axis 1314 can rotate around a third direction (such as...). Figure 6 Rotate back and forth in the Y direction (as shown in the figure) to adjust the pitch angle.

[0078] For example, it can also be seen that the roll axis 1312, yaw axis 1313 and pitch axis 1314 are respectively provided with adjustment knobs 1315. The tester can rotate the corresponding adjustment knobs 1315 to adjust the roll angle of the millimeter-wave radar 300 in the first direction, the yaw angle in the second direction and the pitch angle in the third direction.

[0079] It should be noted that, Figure 6 The gimbal 131 shown is for illustrative purposes only. Because the roll axis 1312, yaw axis 1313, and pitch axis 1314 in the figure are irregularly shaped, and because the roll axis 1312 and pitch axis 1314 are in an adjusted state (relatively slid out) for easier demonstration of the slide rail 1316, therefore... Figure 6 The X, Y, and Z directions shown are for illustrative purposes only and do not represent actual precise measurements. That is, the first direction (X direction) is parallel to the roll axis 1312 in the initial state, the second direction (Z direction) is parallel to the yaw axis 1313 in the initial state, and the third direction (Y direction) is parallel to the pitch axis 1314 in the initial state.

[0080] By adopting the above technical solution, the gimbal 131 can adjust the roll angle, yaw angle and pitch angle of the millimeter-wave radar 300. By changing the attitude angle, it can simulate various angles and positions that the radar may have in actual applications, making the performance test of the millimeter-wave radar 300 more comprehensive and facilitating a comprehensive evaluation of the performance of the millimeter-wave radar 300, thereby ensuring the accuracy and reliability of the millimeter-wave radar 300.

[0081] Specifically, adjusting the roll angle can test the radar performance when the vehicle body is tilted (e.g., when encountering sharp turns or crosswinds), adjusting the yaw angle can test the radar's detection range when turning or changing lanes, and adjusting the pitch angle can test the radar's detection performance at different heights (e.g., when going up or down slopes or passing speed bumps).

[0082] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions.
