Description

Technical Field

[0001] This application relates to the field of radar installation technology, and in particular to an installation detection device. Background Technology

[0002] Millimeter-wave radar refers to detection radar that operates in the millimeter-wave band. It can assist the driving of ordinary vehicles or autonomous vehicles and is generally installed on the left and right sides of the front bumper of a vehicle. Millimeter-wave radar needs to meet very high accuracy requirements to achieve its detection function. However, because millimeter-wave radar is far from the main structure of the vehicle body, relying on the vehicle body's own precision, existing installation fixtures cannot guarantee the installation accuracy of millimeter-wave radar, thus affecting its detection performance. Summary of the Invention

[0003] This application provides an installation detection device, which can ensure the realization of millimeter-wave radar detection function by improving the installation accuracy of millimeter-wave radar.

[0004] This application provides an installation and testing fixture for installing radar on a vehicle. The installation and testing fixture includes a main body and a positioning seat. The main body includes a positioning component for connecting and positioning with the longitudinal beam of the vehicle body. The positioning seat is connected to the main body and is used to cooperate with the radar bracket to position the radar bracket in a determined installation position.

[0005] In one possible design, the main body includes a body portion and a limiting block connected to the body portion, the limiting block being used to limit movement in conjunction with the longitudinal beam.

[0006] In one possible design, the main body includes two pairs of limiting blocks, each pair of limiting blocks cooperating with each other to limit the two sides of the two longitudinal beams respectively.

[0007] In one possible design, the body also includes a gripper for holding the longitudinal beam, the gripper being connected to the body portion.

[0008] In one possible design, the main body also includes a base connected to the main body portion, and the base is rotatably connected to the positioning seat via a pivot.

[0009] In one possible design, the positioning seat is provided with a first limiting hole, the base is provided with a second limiting hole, and the fixing member can pass through the first limiting hole and the second limiting hole in sequence to restrict the rotation of the positioning seat relative to the base.

[0010] In one possible design, the positioning seat includes a first positioning part, the first positioning part having a first surface on the side facing the radar bracket, the first surface being provided with a first protruding rib for abutting and engaging with the radar bracket, the side of the radar bracket facing the first surface being a second surface, and a first gap to be detected between the first surface and the second surface.

[0011] In one possible design, the first surface is provided with a first detection groove, and the installation and testing fixture further includes a first stop pin, which is used to insert between the first detection groove and the second surface to detect the first gap.

[0012] In one possible design, the first surface is provided with a pair of first detection grooves, which are distributed on both sides of the first rib.

[0013] In one possible design, the first positioning part further includes a fixing part embedded in the first protruding rib, the fixing part being able to fix the radar bracket to the positioning seat.

[0014] In one possible design, the positioning base further includes a second positioning part connected to the first positioning part. The second positioning part has a third surface on the side facing the radar bracket. The third surface is provided with a second rib for supporting the radar bracket. The side of the radar bracket facing the third surface is a fourth surface. There is a second gap to be detected between the third surface and the fourth surface.

[0015] In one possible design, the third surface is provided with a second detection groove, and the installation and testing fixture further includes a second stop pin, which is used to insert between the second detection groove and the fourth surface to detect the second gap.

[0016] In one possible design, the third surface is provided with a pair of second detection grooves, which are distributed on both sides of the second rib.

[0017] In this application, the positioning element can be a pin, and the longitudinal beam has corresponding mounting holes. The positioning element extends into the mounting holes, thereby defining the relative position between the positioning element and the longitudinal beam, and further defining the relative position between the installation and testing fixture and the vehicle. The radar bracket is placed on the mounting base, which positions the radar bracket in the defined installation position and fixes the radar bracket to the vehicle body. Because the mounting base is connected to the main body, the installation accuracy of the radar bracket is guaranteed, resulting in high installation accuracy of the millimeter-wave radar mounted on the radar bracket. Furthermore, since the installation and testing fixture provided in this application relies on the positioning points of the vehicle itself, such as the longitudinal beam, for positioning, there are no requirements regarding the environment in which the vehicle is located or the placement of the vehicle during radar installation, resulting in a better user experience.

[0018] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0063] Millimeter-wave radar refers to detection radar operating in the millimeter-wave band, characterized by its short wavelength, wide bandwidth, and strong penetration capability. Installing millimeter-wave radar on vehicles allows for the detection of the surrounding environment, assisting drivers or enabling autonomous driving. Because millimeter-wave radar requires high installation precision and is typically mounted on the front and rear bumpers, relatively far from the main vehicle structure, ensuring the installation accuracy of millimeter-wave radar is a critical issue that needs to be addressed.

[0064] Furthermore, while the radar is designed to be installed in an ideal location, the actual installation location may deviate from this ideal location due to external factors and limitations in technology. The installation accuracy limits the degree of deviation between the actual and ideal installation locations; the higher the installation accuracy, the smaller the deviation.

[0065] This application provides an installation and testing fixture for mounting radar on a vehicle, which can improve the installation accuracy of millimeter-wave radar. For example... Figure 1 and Figure 2 As shown, the installation and testing fixture includes a main body 1 and a positioning seat 2. The main body 1 includes a positioning component 11, which is used to connect and position with the longitudinal beam 7 of the vehicle body. The positioning seat 2 is connected to the main body 1 and is used to cooperate with the radar bracket 8 so that the radar bracket 8 is located in a determined installation position.

[0066] In this embodiment, such as Figure 1 and Figure 2As shown, the positioning element 11 can be a pin, and the longitudinal beam 7 has corresponding mounting holes. The positioning element 11 extends into the mounting holes, thereby defining the relative position of the positioning element 11 and the longitudinal beam 7, and further defining the relative position of the installation and testing fixture and the vehicle. The radar bracket 8 is placed on the mounting base 2, which positions the radar bracket 8 in the defined installation position and fixes the radar bracket 8 to the vehicle body. Since the mounting base 2 is connected to the main body 1, the installation accuracy of the radar bracket 8 is guaranteed, resulting in high installation accuracy of the millimeter-wave radar mounted on the radar bracket 8. In addition, since the installation and testing fixture provided in this application relies on the positioning points of the vehicle itself, such as the longitudinal beam 7, for positioning, there are no requirements regarding the environment in which the vehicle is located or the placement of the vehicle when installing the radar, resulting in a better user experience.

[0067] In one specific implementation, such as Figure 1 and Figure 2 As shown, the main body 1 includes a body part 15 and a limiting block 12 connected to the body part 15. The limiting block 12 is used to cooperate with the longitudinal beam 7 for limiting.

[0068] In this embodiment, such as Figure 1 and Figure 2 As shown, the positioning component 11 can limit the relative position of the installation and testing fixture and the vehicle, and the limiting block 12 can abut against the longitudinal beam 7 to further limit the rotation of the installation and testing fixture relative to the longitudinal beam 7, thereby improving the installation accuracy of the radar bracket 8 and the millimeter-wave radar and ensuring the normal operation of the millimeter-wave radar.

[0069] In one specific implementation, such as Figure 1 and Figure 2 As shown, the main body 1 includes two pairs of limiting blocks 12, each pair of limiting blocks 12 cooperating with each other to limit the two sides of the two longitudinal beams 7 respectively.

[0070] In this embodiment, such as Figure 1 and Figure 2 As shown, the main body 1 is provided with two pairs of limiting blocks 12. Each pair of limiting blocks 12 is spaced apart and positioned opposite each other on both sides of the longitudinal beam 7, thereby limiting the rotation of the main body 15 relative to the longitudinal beam 7 and ensuring the position of the installation and testing fixture relative to the vehicle body. In addition, the limiting blocks 12 are stepped, and each limiting block 12 has two planes that abut against the longitudinal beam 7. Therefore, the contact and limiting between the limiting blocks 12 and the longitudinal beam 7 is relatively stable, providing a reliable installation environment for the radar bracket 8.

[0071] In one specific implementation, such as Figure 1 and Figure 2 As shown, the main body 1 also includes a clamp 13 for holding the longitudinal beam 7, and the clamp 13 is connected to the main body 15.

[0072] In this embodiment, such as Figure 1 and Figure 2 As shown, the main body 1 is limited by the positioning component 11 and the limiting block 12, so that the installation and testing fixture has high positional accuracy. Then, the clamp 13 clamps the longitudinal beam 7, so that the installation and testing fixture is fixed to the longitudinal beam 7. Thus, during the process of installing the radar bracket 8 on the vehicle body, the installation and testing fixture will not move relative to the longitudinal beam 7, providing a stable installation environment for the radar bracket 8 and ensuring the smooth installation of the radar bracket 8.

[0073] In one specific implementation, such as Figure 1 and Figure 2 As shown, the main body 1 also includes a base 14 connected to the main body 15, and the base 14 is rotatably connected to the positioning seat 2 via a rotating shaft 3.

[0074] In this embodiment, such as Figure 1 and Figure 2 As shown, the rotating shaft 3 passes through the base 14 and the positioning seat 2, making the base 14 and the positioning seat 2 rotatably connected. Therefore, when the radar bracket 8 needs to be installed, the positioning seat 2 is rotated to the determined installation position. After the radar bracket 8 is installed on the vehicle body, the positioning seat 2 is rotated away from the determined installation position, and the installation and testing fixture is removed from the longitudinal beam 7, thereby assisting in the installation of the radar bracket 8.

[0075] In one specific implementation, such as Figure 5 and Figure 6 As shown, the positioning seat 2 is provided with a first limiting hole 21, and the base 14 is provided with a second limiting hole 141. The fixing member 4 can pass through the first limiting hole 21 and the second limiting hole 141 in sequence to restrict the rotation of the positioning seat 2 relative to the base 14.

[0076] In this embodiment, such as Figure 5 and Figure 6 As shown, when the positioning seat 2 rotates to the designated installation position, the first limiting hole 21 on the mounting seat 2 and the second limiting hole 141 on the base 14 are aligned. The fixing member 4 can pass through the first limiting hole 21 and the second limiting hole 141 in sequence, restricting the relative rotation of the positioning seat 2 and the base 14, thereby fixing the position of the positioning seat 2 and ensuring the smooth installation of the radar bracket 8 placed on the positioning seat 2. The fixing member 4 can be a positioning pin.

[0077] In one specific implementation, such as Figure 3 , Figure 4 and Figure 7 As shown, the positioning seat 2 includes a first positioning part 22. The first positioning part 22 has a first surface 221 on the side facing the radar bracket 8. The first surface 221 is provided with a first rib 222 for abutting and cooperating with the radar bracket 8. The side of the radar bracket 8 facing the first surface 221 is a second surface 81. There is a first gap 24 to be detected between the first surface 221 and the second surface 81.

[0078] like Figure 4 As shown, when the positioning seat 2 is in a determined installation position, the direction parallel to the first surface 221 and perpendicular to the height direction of the positioning seat 2 is defined as the first direction X, the height direction of the positioning seat 2 is defined as the third direction Z, and the direction perpendicular to both the first direction X and the third direction Z is defined as the second direction Y.

[0079] In this embodiment, such as Figure 3 , Figure 4 and Figure 7 As shown, the first rib 222 fits against the second surface 81 of the radar bracket 8, constraining the rotation of the radar bracket 8 relative to the positioning seat 2 around the first direction X and its relative height in the second direction Y. The mounting surface 83 of the radar bracket 8 is then fitted against the vehicle body, fixing the radar bracket 8 to the vehicle body, specifically through bolt connection or other methods. At this time, a first gap 24 is formed between the first surface 221 and the second surface 81. The smaller the difference in width of the first gap 24 at different positions, the smaller the angle by which the radar bracket 8 deviates from its theoretical installation position around the third direction Z, and the higher the installation accuracy of the radar bracket 8. Therefore, the installation accuracy of the radar bracket 8 can be detected through the first gap 24.

[0080] In one specific implementation, such as Figure 3 , Figure 4 and Figure 8 As shown, the first surface 221 is provided with a first detection groove 223. The installation and testing fixture also includes a first stop pin 5, which is used to insert between the first detection groove 223 and the second surface 81 to detect the first gap 24.

[0081] In this embodiment, such as Figure 3 and Figure 8 As shown, the installation accuracy requirement for millimeter-wave radar is generally ±1°. By setting the depth of the first detection groove 223, when the angle of deviation of the radar bracket 8 from the theoretical installation position in the third direction Z after it is fixed to the vehicle body is within ±1°, the first stop pin 5 can be smoothly inserted between the first detection groove 223 and the second surface 81; when the angle of deviation of the radar bracket 8 from the theoretical installation position in the third direction Z after it is fixed to the vehicle body is greater than ±1°, the first stop pin 5 cannot be inserted between the first detection groove 223 and the second surface 81, thereby detecting the installation accuracy of the radar bracket 8.

[0082] In one specific implementation, such as Figure 3 , Figure 4 and Figure 8 As shown, the first surface 221 is provided with a pair of first detection grooves 223, which are distributed on both sides of the first rib 222.

[0083] In this embodiment, such as Figure 3 and Figure 8 As shown, the radar bracket 8 is shaped like a seesaw. The position where the second surface 81 abuts against the first rib 222 can be compared to the fulcrum in the middle of the seesaw. When the radar bracket 8 deflects around the fulcrum (i.e. around the third direction Z), the width of the first gap 24 on both sides of the first rib 222 increases on one side and decreases on the other. This allows the first stop pin 5 to be smoothly inserted between the first detection groove 223 and the second surface 81 when the angle of the radar bracket 8 deviating from the theoretical installation position around the third direction Z after it is fixed to the vehicle body is within ±1°. When the angle of the radar bracket 8 deviating from the theoretical installation position around the third direction Z after it is fixed to the vehicle body is greater than ±1°, the first stop pin 5 can only be inserted between the first detection groove 223 and the second surface 81 on one side of the first rib 222, and cannot be smoothly inserted on the other side. This allows for the detection of the installation accuracy of the radar bracket 8, and the detection method is convenient, fast, and efficient.

[0084] In one specific implementation, such as Figure 4 As shown, the first positioning part 22 also includes a fixing part 224 embedded in the first protruding rib 222, which can fix the radar bracket 8 to the positioning seat 2.

[0085] In this embodiment, such as Figure 3 and Figure 4 As shown, the fixing part 224 can be a magnet, and the radar bracket 8 can be attracted and fixed to the first protruding rib 222 through the fixing part 224, which makes it convenient for installers to install the radar bracket 8 on the vehicle body. At the same time, the fixing part 224 is not limited to the fixed position of the radar bracket 8, so the installers can easily adjust the position of the radar bracket 8 to fit the vehicle body.

[0086] In one specific implementation, such as Figure 3 , Figure 4 and Figure 8 As shown, the positioning base 2 also includes a second positioning part 23 connected to the first positioning part 22. The second positioning part 23 has a third surface 231 on the side facing the radar bracket 8. The third surface 231 is provided with a second rib 232 for supporting the radar bracket 8. The side of the radar bracket 8 facing the third surface 231 is a fourth surface 82. There is a second gap 25 to be detected between the third surface 231 and the fourth surface 82.

[0087] In this embodiment, such as Figure 3 , Figure 4 and Figure 8As shown, the second rib 232 abuts against the fourth surface 82 of the radar bracket 8, defining the relative height of the radar bracket 8 relative to the positioning seat 2 in the third direction Z. At this time, a second gap 25 is formed between the third surface 231 and the fourth surface 82. The smaller the difference in width of the second gap 25 at different positions, the smaller the angle of the radar bracket 8 deviating from the theoretical installation position around the second direction Y, and the higher the installation accuracy of the radar bracket 8. Therefore, the installation accuracy of the radar bracket 8 can be detected by the second gap 25.

[0088] In one specific implementation, such as Figure 3 , Figure 4 and Figure 8 As shown, the third surface 231 is provided with a second detection groove 233. The installation and detection fixture also includes a second stop pin 6, which is used to insert between the second detection groove 233 and the fourth surface 82 to detect the second gap 25.

[0089] In this embodiment, such as Figure 3 and Figure 8 As shown, by setting the depth of the second detection groove 233, when the angle of deviation of the radar bracket 8 from the theoretical installation position around the second direction Y after it is fixed to the vehicle body is within ±1°, the second through-stop pin 6 can be smoothly inserted between the second detection groove 233 and the fourth surface 82; when the angle of deviation of the radar bracket 8 from the theoretical installation position around the second direction Y after it is fixed to the vehicle body is greater than ±1°, the second through-stop pin 6 cannot be inserted between the second detection groove 233 and the fourth surface 82, thereby detecting the installation accuracy of the radar bracket 8.

[0090] In one specific implementation, such as Figure 3 , Figure 4 and Figure 8 As shown, the third surface 231 is provided with a pair of second detection grooves 233, which are distributed on both sides of the second rib 232.

[0091] In this embodiment, such as Figure 3 and Figure 8As shown, the radar bracket 8 is shaped like a seesaw. The position where the fourth surface 82 abuts against the second rib 232 can be compared to the fulcrum in the middle of the seesaw. When the radar bracket 8 deflects around the fulcrum (i.e. around the second direction Y), the width of the second gap 25 on both sides of the second rib 232 increases on one side and decreases on the other. This allows the second stop pin 6 to be smoothly inserted between the second detection groove 233 and the fourth surface 82 when the angle of the radar bracket 8 deviating from the theoretical installation position around the second direction Y after it is fixed to the vehicle body is within ±1°. When the angle of the radar bracket 8 deviating from the theoretical installation position around the second direction Y after it is fixed to the vehicle body is greater than ±1°, the second stop pin 6 can only be inserted between the second detection groove 233 and the fourth surface 82 on one side of the second rib 232, and cannot be smoothly inserted on the other side. This allows for the detection of the installation accuracy of the radar bracket 8, and the detection method is convenient, fast, and efficient.

[0092] The installation accuracy of the radar bracket 8 is checked using the first stop pin 5 and the second stop pin 6. When the installation accuracy meets the design requirements, the installer can remove the fixing piece 4 that restricts the relative rotation of the base 14 and the positioning seat 2, rotate the positioning seat 2 away from the installation position, release the clamp 13, and disconnect the connection between the main body 1 and the longitudinal beam 7. The installation and testing fixture can then be retrieved for future use. Simultaneously, the radar is installed on the radar bracket 8, completing the successful installation of the radar. Therefore, the installation and testing fixture provided in this application can control the deviation of the radar installation angle within ±1°, achieving high installation accuracy.

[0093] Furthermore, if the first stop pin 5 cannot be smoothly inserted between the first detection groove 223 and the second surface 81, or if the second stop pin 6 cannot be inserted between the second detection groove 233 and the fourth surface 82, it may be due to an error in the installation process of the radar bracket 8, a design or manufacturing defect in the radar bracket 8, or a design or manufacturing defect at the vehicle body installation location. Installers or designers can further investigate the cause and make improvements. Therefore, the installation and testing fixture provided in this application also has the function of identifying and detecting vehicle body precision problems, and is used for the control and improvement of vehicle body precision.

[0094] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
