Description

Technical Field

[0001] This application relates to the field of measurement technology, and particularly to a detection system. Background Art

[0002] With the development of intelligent driving technology, more and more vehicles begin to use lidar to assist drivers in automatic navigation. The lidar is often set to be retractable or rotatable relative to the vehicle. Specifically, when the lidar is activated, the radar extends out of the vehicle body surface for detection. When the lidar is deactivated, the radar retracts into the vehicle body, and the radar cover is flush with the vehicle body surface.

[0003] Since the numerical values of the gap and surface difference between the radar cover and the vehicle body surface will affect the wind resistance coefficient and aesthetic appearance of the vehicle when the radar retracts into the vehicle body, after the vehicle body is processed and manufactured, the staff often detects the numerical values of the gap and surface difference between the radar cover and the vehicle body surface, and judges whether the processing quality of the vehicle body meets the target requirements according to the size of the detection results.

[0004] In the related art, quality inspection personnel use a vehicle body detection system composed of the lidar actually used in the vehicle and a coordinate measuring machine to detect the processing quality of the vehicle body. When the vehicle body detection system works, the quality inspection personnel install the lidar actually used in the vehicle on the vehicle body, and use the coordinate measuring machine to detect the numerical values of the gap and surface difference between the cover of the lidar and the vehicle body surface.

[0042] Please refer to Figures 1 to 3 , Figure 1 , which shows a top view of a simulated radar in an embodiment of this application. A detection system 1000 provided by an embodiment of this application includes: a simulated radar 1100 and a detection component (not shown). The simulated radar 1100 is used to be assembled in a radar mounting hole (not shown) of a vehicle body 2000. The detection component is used to detect the distance between the outer peripheral surface of the simulated radar 1100 and the hole wall of the radar mounting hole, and / or the surface difference between the side of the simulated radar 1100 close to the outer surface of the vehicle body 2000 along a first direction and the outer surface of the vehicle body 2000. The first direction is the axial direction of the radar mounting hole.

[0043] In the detection system 1000 of this embodiment, during use, the staff assembles the simulation radar 1100 into the radar mounting hole of the vehicle body 2000, and uses the detection component to detect the distance between the outer peripheral surface of the simulation radar 1100 and the hole wall of the radar mounting hole, and / or the surface difference between the side of the simulation radar 1100 close to the outer surface of the vehicle body 2000 along the first direction and the outer surface of the vehicle body 2000. Compared with the radar actually installed in the vehicle, the size of the simulation radar 1100 is closer to the radar model used by the staff when designing the vehicle body 2000, that is, the dimensional accuracy of the simulation radar 1100 is higher than that of the radar actually installed in the vehicle. Therefore, the data detected by the detection component according to the simulation radar 1100 is more accurate, the detection result accuracy of the detection system 1000 for the vehicle body 2000 is higher, and the measurement of the processing quality of the vehicle body 2000 is more accurate. In summary, in this embodiment, by replacing the radar actually installed in the vehicle with the simulation radar 1100, a more accurate measurement of the processing quality of the vehicle body 2000 can be achieved.

[0044] Please refer to Figure 3 , in some embodiments, the detection component includes a gap detector (not shown) and a surface difference detector (not shown). The gap detector is used to detect the distance D1 between the outer peripheral surface of the simulation radar 1100 and the hole wall of the radar mounting hole, and the surface difference detector is used to detect the surface difference S1 between the side of the simulation radar 1100 close to the outer surface of the vehicle body 2000 along the first direction and the outer surface of the vehicle body 2000.

[0045] In this embodiment, by setting the detection component to be composed of an independent gap detector and a surface difference detector, the staff can directly use the gap detector and the surface difference detector to measure the vehicle body 2000 on the production line without removing the vehicle body 2000 from the production line, so as to complete the detection of the quality of the vehicle body 2000 in less time, thereby saving the time required for quality detection of a batch of processed vehicle bodies 2000, and facilitating the rapid identification of the stability of the functional dimensions of the processed vehicle body 2000. Compared with the traditional three-coordinate off-line measurement method, the detection system 1000 does not need to remove the vehicle body 2000 from the production line, requires less time and personnel to measure the processing quality of the vehicle body 2000, and has a lower measurement cost.

[0046] In some embodiments, the gap measuring instrument is a gap gauge (not shown).

[0047] Please refer to Figure 3 And Figure 4 , in some embodiments, the simulation radar 1100 includes a radar simulation part 1110 and a base 1120.

The radar simulation part 1110 is used to pass through the radar mounting hole, and the base 1120 is used to connect to the vehicle body 2000.

[0048] In this embodiment, by connecting the base 1120 to the vehicle body 2000, the position of the radar simulator 1110 in the radar mounting hole can be fixed. It should be noted that the radar simulator 1110 is used to simulate the radar to be installed on the vehicle.

[0049] In some embodiments, the radar simulator 1110 is made by machining processes so that the dimensional accuracy of the radar simulator 1110 is the same as that of the radar model used by the staff when designing the vehicle body.

[0052] In this embodiment, the weight reduction hole 1130 sequentially penetrates through the radar simulator 1110 and the base 1120 along the first direction, which can reduce the weight of the simulated radar 1100, facilitate a single staff member to carry the simulated radar 1100, and reduce the fatigue of the detection personnel.

[0053] In some embodiments, the weight of the simulated radar 1100 is between 2 kg and 3.5 kg.

[0054] In some embodiments, the simulated radar 1100 is made of common metals such as aluminum alloy, copper, and iron, so that the simulated radar 1100 is not easily deformed, thereby improving the durability of the simulated radar 1100.

A fastener (not shown) is inserted into the base assembly hole 1151, and the fastener passes through the base assembly hole 1151 for cooperation with a radar assembly hole (not shown) on the vehicle body 2000.

[0057] In this embodiment, the simulated radar 1100 is installed on the vehicle body 2000 by cooperating with the fasteners and the radar assembly holes, so that the simulated radar 1100 and the radar actually installed on the vehicle share the same set of radar assembly holes for assembly with the vehicle body 2000. On the one hand, the utilization rate of the radar assembly holes on the vehicle body 2000 is improved, avoiding the need to drill new holes on the vehicle body 2000 to cooperate with the fasteners. On the other hand, it can ensure that the simulated radar 1100 and the radar actually installed on the vehicle are fixed in the same position in the radar mounting holes of the vehicle body 2000.

Each fastener passes through the corresponding base assembly hole 1151 and cooperates with the corresponding radar assembly hole.

[0060] In this embodiment, by setting up a plurality of base assembly holes 1151 and inserting a fastener for connecting the simulated radar 1100 and the vehicle body 2000 into each base assembly hole 1151, the simulated radar 1100 can be more firmly installed on the vehicle body 2000, thereby completely fixing the simulated radar 1100 to the vehicle body 2000.

[0061] Please continue reading Figure 4 In some embodiments, at least one positioning boss 1160 is provided on the side of the base 1120 close to the vehicle body 2000, and the positioning boss 1160 extends from the base 1120 toward the vehicle body 2000 along a first direction, and a base assembly hole 1151 is provided on the positioning boss 1160, and the base assembly hole 1151 passes through the positioning boss 1160 and the base 1120 along the first direction.

That is, the processing equipment only needs to fine-process the surface of the positioning boss 1160 facing away from the base 1120, and there is no need to perform high-precision processing on the entire side of the base 1120 close to the vehicle body 2000.

[0063] In some embodiments, a plurality of positioning bosses 1160 are provided on the side of the base 1120 close to the vehicle body 2000, and the plurality of positioning bosses 1160 are arranged around the outer side of the radar simulation component 1110. Each positioning boss 1160 extends from the base 1120 toward the vehicle body 2000 along a first direction, and a base assembly hole 1151 is provided in each positioning boss 1160.

[0064] In some embodiments, each positioning boss 1160 extends from the base 1120 to the vehicle body 2000 by the same distance along the first direction.

[0065] In some embodiments, the side of the positioning boss 1160 facing away from the base 1120 contacts the radar positioning surface (not shown) on the vehicle body 2000, so that the simulated radar 1100 and the radar actually installed on the vehicle share the same set of radar positioning surfaces on the vehicle body 2000. On the one hand, the utilization rate of the radar positioning surfaces on the vehicle body 2000 is improved, avoiding the need to reprocess the radar positioning surfaces on the vehicle body 2000 to contact the simulated radar 1100. On the other hand, it can ensure that the simulated radar 1100 and the radar actually installed on the vehicle have the same position in the radar mounting hole of the vehicle body 2000.

[0068] In some embodiments, the base positioning hole 1141 is made by machining technology to ensure position accuracy and dimensional accuracy.

[0069] In some embodiments, the position and size of the base positioning hole 1141 on the simulated radar 1100 are the same as the position and size of the positioning hole in the radar actually installed in the car.

[0070] In some embodiments, the positioning pin 1142 and the base 1120 are integrally formed, and the structure is simple.

[0073] In this embodiment, by setting a plurality of positioning pins 1142, each positioning pin 1142 cooperates with the corresponding radar positioning hole on the vehicle body 2000, so that the coaxiality between the axis of the base assembly hole 1151 and the axis of the corresponding radar assembly hole on the vehicle body 2000 can be improved, thereby achieving effective connection between the fastener in the base assembly hole 1151 and the radar assembly hole on the vehicle body 2000.
