[0002] In the field of intelligent driving, the intelligent forward-looking integrated device is a key device that can realize a variety of functions, such as lane departure warning, forward collision warning and pedestrian detection, thereby helping drivers avoid potential dangers and improve driving safety.
[0003] In related technologies, functional testing methods for intelligent forward-looking integrated machines fall into two categories: real-vehicle functional testing and bench functional testing. Real-vehicle functional testing requires a relatively mature vehicle condition and is typically conducted in the mid-to-late stages of automotive development. Bench functional testing involves building a test environment similar to that of a real vehicle and is generally used in the early stages of automotive development and throughout its entire lifecycle; this method is more convenient. However, bench functional testing, due to the need to simulate a real-vehicle environment, requires a relatively large testing device, making it difficult to simultaneously meet the requirements of miniaturization, portability, and low cost.

[0021] In some embodiments, the second end of the support plate is provided with a stop rib, which is perpendicular to the plane of the support plate. The stop rib is used to abut against the side of the bracket body away from the fixing block to limit the bracket body.
[0022] In some embodiments, the bracket body has a protruding structure on the side away from the fixing block, and the number of stop ribs is set to two, with a limiting gap between the two stop ribs, and the protruding structure is engaged in the limiting gap.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0051] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0052] Please see Figure 1 , Figure 2 and Figure 3 The testing apparatus provided in this application includes an adjustment component 10 and a test bracket 20 for supporting the component 50 to be tested.
[0053] The component to be tested 50 can be an in-vehicle product to be tested, such as a smart front-view all-in-one machine or an in-vehicle camera module.
[0054] The adjustment assembly 10 includes a height adjustment rod 11 and an angle adjustment rod 12, the angle adjustment rod 12 being movably fitted into the height adjustment rod 11.
[0055] In this way, when it is necessary to adjust the height of the intelligent front-view all-in-one machine, the angle adjustment lever 12 is moved relative to the height adjustment lever 11 to achieve the position adjustment of the intelligent front-view all-in-one machine in the height direction.
[0056] To facilitate the rotational connection between the test bracket 20 and the angle adjustment rod 12, the angle adjustment rod 12 is provided with a rotational positioning structure 121, and the test bracket 20 is provided with a rotational connection structure 24. The rotational connection structure 24 is rotatably connected to the rotational positioning structure 121, so that the test bracket 20 rotates relative to the angle adjustment rod 12 and is positioned in the rotational positioning structure 121 after the position of the test bracket 20 is adjusted.
[0057] In this way, when it is necessary to adjust the angle of the intelligent front-view all-in-one machine, the test bracket 20 is rotated relative to the angle adjustment rod 12 to achieve the angle adjustment of the intelligent front-view all-in-one machine.
[0058] During testing, the component to be tested 50 is first placed on the test bracket 20. Then, the height position of the angle adjustment rod 12 relative to the height adjustment rod 11 and the angle position of the test bracket 20 relative to the angle adjustment rod 12 are adjusted according to the test requirements to simulate the real vehicle environment when the component to be tested 50 is functionally tested.
[0059] Compared to traditional testing devices, the testing device provided in this application embodiment can be used for functional testing of intelligent forward-looking integrated machines. This testing device integrates height and angle adjustment functions. By realizing the composite adjustment of the height and angle of the intelligent forward-looking integrated machine, it can cover more testing scenarios. For example, in real-world situations such as curves and uphill / downhill slopes, the angle of the intelligent forward-looking integrated machine needs to be adapted to the installation height, thereby more accurately simulating the real vehicle environment. In addition, the testing device adopts a miniaturized design to avoid bulky size, making it easy to transport and carry. At the same time, the device has fewer parts, a simple structure, simplified assembly and adjustment processes, and lower production costs, solving the problem that traditional testing devices cannot simultaneously meet the requirements of miniaturization, portability, and low cost.
[0060] It should be noted that the test bracket 20 is set on top of the angle adjustment rod 12, so that the test device is mainly set along the height direction. This makes the test device occupy a small area and further avoids being bulky.
[0061] Please refer to the following: Figure 4 , Figure 5 and Figure 6 The rotary positioning structure 121 includes a rotary positioning head 1211 located at one end of the angle adjustment rod 12 near the test bracket 20, and a rotary connecting groove 1212 and a rotary connecting hole 1213 located on the rotary positioning head 1211. The rotary connecting hole 1213 is located on both sides of the rotary connecting groove 1212. Correspondingly, the rotary connecting structure 24 includes a rotary connecting protrusion 241 integrally formed on the test bracket 20 and rotary connecting posts 242 located on both sides of the rotary connecting protrusion 241.
[0062] The rotary connecting protrusion 241 is embedded in the rotary connecting groove 1212, and the rotary connecting post 242 is embedded in the rotary connecting hole 1213.
[0063] As can be seen, the two rotating connecting columns 242 can serve as the rotation axis of the test bracket 20. The test bracket 20 can rotate along the axis of the two rotating connecting columns 242 to achieve the angle adjustment of the intelligent front-view all-in-one machine.
[0064] Furthermore, in order to position the test bracket 20 in the rotary positioning structure 121 after the position adjustment is completed, a first tooth surface 1214 is provided in the rotary connecting groove 1212, and a second tooth surface 243 is provided in the rotary connecting protrusion 241, with the first tooth surface 1214 meshing with the second tooth surface 243.
[0065] In this way, by engaging the second tooth surface 243 of the rotary connecting protrusion 241 with the first tooth surface 1214 in the rotary connecting groove 1212, the test bracket 20 can be positioned in the rotary positioning structure 121 after the position adjustment is completed, based on the rotation of the test bracket 20 relative to the angle adjustment rod 12.
[0066] In some embodiments, the two rotating connecting columns 242 can also be configured as damping connecting columns, and correspondingly, the two rotating connecting holes 1213 can be configured as damping connecting holes. In this way, the test bracket 20 can be stopped at any rotation position by rotating the damping connecting columns and the corresponding damping connecting holes and utilizing the damping force of both during the rotation process.
[0067] To facilitate the assembly of the rotating connection structure 24 of the test bracket 20 onto the rotating positioning head 1211 of the angle adjustment rod 12, the rotating positioning head 1211 is also provided with a guide slope 1215. There are two guide slopes 1215, which can be respectively located above the two rotating connection holes 1213 (on the side closer to the test bracket 20). In this way, during installation, the rotating connection column 242 slides into the corresponding rotating connection hole 1213 via the guide slope 1215.
[0068] It is understandable that the two guide ramps 1215 can form an flared shape (or a trumpet shape) above the two rotary connecting holes 1213. The guide ramps 1215 have a guiding function, which can guide the rotary connecting column 242 to slide smoothly into the corresponding rotary connecting hole 1213, thereby fixing the test bracket 20 to the angle adjustment rod 12 and enabling mutual rotational movement.
[0069] Specifically, a portion of the structure can be cut off at the top of the rotating connection hole 1213 to form an angled structure. During assembly, the rotating connection column 242 can be smoothly slid into the rotating connection hole 1213 of the angle adjustment rod 12, so that the test bracket 20 and the angle adjustment rod 12 are fixed and can rotate relative to each other.
[0070] To facilitate the adjustment of the angle adjustment rod 12 in height and its positioning after adjustment to the target height, the height adjustment rod 11 is provided with a fastening connection hole 111 and a height adjustment hole 112 for adjusting the height of the angle adjustment rod 12. The fastening connection hole 111 communicates with the height adjustment hole 112, and the axis of the fastening connection hole 111 is perpendicular to the axis of the height adjustment hole 112. Furthermore, the adjustment assembly 10 also includes a fastening connector 13, which is screwed into the fastening connection hole 111, so that the angle adjustment rod 12 is fixed to the height adjustment rod 11.
[0071] Of course, depending on actual needs, the fastening connector 13 is a fastening screw, and the fastening connection hole 111 is a threaded hole. The angle adjusting rod 12 is inserted into the height adjusting hole 112 of the height adjusting rod 11. During use, the height of the angle adjusting rod 12 is adjusted up and down. When it reaches the appropriate height, the fastening screw is screwed into the fastening connection hole 111 to lock the angle adjusting rod 12 and fix it in the height adjusting rod 11.
[0072] To facilitate support of the height adjustment rod 11, the testing device also includes a base 30, which has a threaded connection hole. The end of the height adjustment rod 11 away from the testing bracket 20 is threadedly connected to the threaded connection hole.
[0073] Considering that the testing device is relatively heavy and has a certain height, a base 30 is provided at the bottom of the testing device. The base 30 is threadedly engaged with the height adjustment rod 11 for easy assembly and disassembly.
[0074] In addition, the testing device also includes a counterweight 40, which is detachably connected to the side of the base 30 away from the height adjustment rod 11. Of course, the counterweight 40 can also be threaded to the base 30. When the product is heavy, a preset number of counterweights 40 can be added below the base 30 as needed. The counterweights 40 and the base 30 are threaded together to ensure the stability of the overall structure.
[0075] Please refer to the following: Figure 7 The test bracket 20 includes a bracket body 21, a support plate 22, and a positioning component 23.
[0076] Please refer to the following: Figure 8 and Figure 9 The support body 21 has a contoured groove 211 for mounting the component 50 to be tested. A support plate 22 supports the support body 21. A fixing block 221 is located at the first end of the support plate 22. The positioning component 23 includes a positioning rod 231 and a positioning elastic element 232. The positioning rod 231 is movably inserted into the fixing block 221. Limiting elements 233 are connected to both ends of the positioning rod 231. The two ends of the positioning elastic element 232 abut against the fixing block 221 and the limiting element 233 near the support body 21, respectively, causing the positioning rod 231 to tend to move towards the second end of the support plate 22. Alternatively, the positioning elastic element 232 can be a compression spring, and the limiting element 233 can be a stop screw.
[0077] Specifically, a fixing block 221 is set at the first end (rear end) of the support plate 22, and a circular opening is set on the fixing block 221. The positioning rod 231 passes through the circular opening. In addition, a circular groove of a certain depth is set in the circular opening. The compression spring is fitted into the positioning rod 231. At the same time, a stop screw is screwed into both ends of the positioning rod 231. One end of the compression spring abuts in the circular groove, and the other end abuts in the stop screw at the front end.
[0078] In actual use, the spring is compressed by stretching the positioning rod 231, which then inserts the bracket body 21 and the intelligent front-view all-in-one machine into it. Then it is released, and the spring force locks the bracket body 21 and the intelligent front-view all-in-one machine into the support plate 22.
[0079] Please refer to the following: Figure 10During assembly, the intelligent front-view all-in-one machine is first placed into the bracket body 21. The bracket body 21 has a contour structure (contour groove 211) made according to the appearance of the intelligent front-view all-in-one machine. Specifically, the bracket body 21 is recessed to a certain extent according to the appearance of the intelligent front-view all-in-one machine in the height direction, and a guide chamfer and a certain gap are left in the mating area in the contour groove 211. This makes it easy for the intelligent front-view all-in-one machine to be installed on the bracket body 21.
[0080] In addition, considering the requirements of portability and lightweight, the main material of the test bracket 20 can be plastic, and the processing method can be 3D printing or machining. The bracket body 21 can be made into different contour structures according to different projects or different product shapes.
[0081] In some embodiments, the second end of the support plate 22 is provided with a stop rib 222, the stop rib 222 is perpendicular to the plane where the support plate 22 is located, and the stop rib 222 is used to abut against the side of the bracket body 21 away from the fixing block 221 to limit the bracket body 21.
[0082] In this way, a stop rib 222 is provided at the second end (front end) of the support plate 22. The stop rib 222 cooperates with the front end face of the bracket body 21 to restrict the forward movement of the bracket body 21.
[0083] Furthermore, the bracket body 21 has a protruding structure 212 on the side away from the fixing block 221, and the number of stop ribs 222 is set to two, with a limiting gap between the two stop ribs 222, and the protruding structure 212 is locked in the limiting gap.
[0084] In other words, a protruding structure 212 is provided on the support body 21. The protruding structure 212 is locked in the limiting gap between the two stop ribs 222. The two interact with each other to limit the left and right displacement of the support body 21.
[0085] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0086] The testing apparatus provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
