Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ADAS vision calibration and testing technology, and in particular relates to an ADAS vision calibration and testing device. Background Technology
[0002] ADAS is a vehicle-mounted safety driving assistance system that includes hardware components such as radar sensors and cameras, as well as software systems. ADAS assists in driving and improves vehicle safety. For example, its warning functions can alert drivers to obstacles in front and behind, allowing them to avoid collisions.
[0003] When the cameras or sensors on a vehicle change, such as after a collision, and after replacing the sensors or cameras, the ADAS needs to be recalibrated to ensure the accuracy of the ADAS system.
[0004] The current calibration method involves using ADAS calibration equipment to calibrate the vehicle. Specifically, after the vehicle is driven to the calibration workbench and its posture is corrected, the front, rear, and side positions of the vehicle are calibrated using ADAS calibration equipment. The calibration method is target calibration.
[0005] For example, during the lateral calibration of a vehicle, a target needs to be installed on each tire of the vehicle, and the positions of the targets need to be kept in correspondence to improve the accuracy of the calibration.
[0006] Because tires, especially tires from different vehicles, vary significantly in size, mounting targets on tires is difficult. This is because different tire models cannot be mounted using a single target device. Secondly, due to the ring-shaped structure of tires, the target itself is also difficult to securely attach to the tire.
[0007] The aforementioned challenges are one of the difficulties in the ADAS calibration process, while fixing the targets at the front and rear of the vehicle is relatively simple. Therefore, how to easily and accurately install targets on different tire models of different vehicles during actual calibration is a pressing technical problem that needs to be solved in the current ADAS calibration process. Utility Model Content
[0008] Based on the above background, the purpose of this utility model is to provide an ADAS visual calibration and detection device.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] An ADAS vision calibration and detection device includes a tire target mechanism that cooperates with an ADAS vision calibration device. The tire target mechanism includes a target frame on which a target plate is mounted.
[0011] The target frame is equipped with several adjustable locking structures that lock onto the tires.
[0012] The adjustable locking structure includes a movable locking plate, on which a claw structure is installed. The tire target mechanism grips the tire through the cooperation between the claw structures.
[0013] A traction adjustment screw is rotatably connected to the movable card plate, and an adjustment component that drives the traction adjustment screw to move is rotatably connected to the target frame;
[0014] The adjusting component includes a rotating solenoid rotatably connected to the target frame, and the rotating solenoid is threadedly connected to the pulling adjusting screw.
[0015] The tension adjusting screw is equipped with scale markings.
[0016] Preferably, the longitudinal cross-sectional shape of the target frame is square;
[0017] The target frame has four adjustable locking structures arranged in a circumferential array.
[0018] Preferably, a mounting hole is provided at the center of the side wall of the target frame, a bearing is installed in the mounting hole, and the rotating solenoid is fixedly connected to the inner ring of the bearing;
[0019] During the rotation of the solenoid, the adjusting screw is moved by pulling it with the bearing as the fulcrum.
[0020] Preferably, a torsion ring is fixedly connected to the inner end of the rotating solenoid;
[0021] The outer wall of the torsion ring has a number of circumferentially distributed protruding ribs integrally formed.
[0022] Preferably, the movable card plate has an integrally formed adjustment part with spaced intervals on the upper and lower sides, and the claw structure is installed on the adjustment part.
[0023] Preferably, the adjusting part is provided with sliding openings, and the claw structure includes claw plates that are slidably connected in the sliding openings;
[0024] A horizontal screw is fixedly connected inside the sliding groove, and a barrier nut that blocks the outside of the claw plate is threaded onto the horizontal screw.
[0025] Preferably, the horizontal screw is provided with scale markings.
[0026] Preferably, a target plate is installed at the center of the side wall of the target frame;
[0027] The target plate is slidably mounted on the target frame.
[0028] Preferably, the upper and lower ends of the rear sidewall of the target frame are fixedly connected to slide rails, and the slide rails are provided with limiting grooves. The top and bottom of the target plate are slidably connected in the limiting grooves.
[0029] This utility model has the following beneficial effects:
[0030] 1. During the operation, the distance between the four target plates is pre-adjusted according to the size of the tire. During the adjustment, the length of adjustment of the four target plates must be the same.
[0031] During the adjustment process, the rotating solenoid is rotated. Because the rotating solenoid is threadedly connected to the traction adjustment screw, under the threaded pushing force of the rotating solenoid and the traction adjustment screw, the traction adjustment screw carries the claw structure toward the target frame. During this process, as the distance between the claw structures decreases, the claw structures gradually engage with the center of the upper, lower, left, and right side walls of the tire.
[0032] Meanwhile, the aforementioned traction adjustment screws are equipped with scale markings. These markings ensure that the four traction adjustment screws are pulled the same distance during operation, thus guaranteeing the accurate positioning of the target plate.
[0033] 2. During the operation, the operator adjusts the claw plate until it contacts the tire, then adjusts the spacer nut until it blocks the outside of the claw plate, and pulls the adjusting screw as described in the above embodiment to fully clamp the claw plate onto the tire.
[0034] During the adjustment process described above, the clamping is first adjusted according to the tire size. Secondly, during the adjustment process, the position of each adjustment locking structure and the claw plate is controlled to be the same, ensuring that the target plate is still located in the center of the tire after adjustment.

[0045] Example 1
[0046] like Figure 1-5As shown, an ADAS vision calibration and testing device includes a tire target mechanism that works in conjunction with an ADAS vision calibration device. Specifically, during the ADAS vision calibration and testing process, the ADAS vision calibration device is used to calibrate and standardize the vehicle. Simultaneously, similar to existing calibration methods, the tire target mechanism is used to mount targets onto the vehicle's tires, enabling lateral calibration of the vehicle during the ADAS vision calibration process.
[0047] Meanwhile, the tire target mechanism includes a target frame 1 (the longitudinal cross-sectional shape of the target frame 1 is square), and a target plate 2 is installed on the target frame 1; the target plate 2 cooperates with the ADAS vision calibration equipment.
[0048] In order to solve the problem of installing target plates on different models of vehicles and tires of different sizes, the target frame 1 is equipped with four adjustable locking structures 4 arranged in a ring array on the tire.
[0049] Specifically, the adjusting locking structure 4 includes a movable locking plate 42, on which a claw structure is installed. The tire target mechanism grips the tire through the cooperation between the claw structures.
[0050] Specifically, a tension adjusting screw 44 is rotatably connected to the movable clamping plate 42 (the tension adjusting screw 44 is limited to rotating on the movable clamping plate 42; correspondingly, a rotating connecting seat is fixedly connected to the movable clamping plate 42, the same as the existing limited rotation method, a T-shaped groove is opened on the rotating connecting seat, and a T-shaped rotating seat is fixedly connected to the end of the tension adjusting screw 44, the T-shaped rotating seat is limited to rotating within the T-groove). An adjusting component that drives the tension adjusting screw 44 to move is rotatably connected to the target frame 1.
[0051] Specifically, the aforementioned adjusting component includes a rotating solenoid 47 rotatably connected to the target frame 1, and the rotating solenoid 47 is threadedly connected to the tension adjusting screw 44.
[0052] Specifically, a mounting hole is provided at the center of the side wall of the target frame 1, and a bearing 45 is installed in the mounting hole. The rotating solenoid 47 is fixedly connected to the inner ring of the bearing 45. During the rotation of the rotating solenoid 47, the adjusting screw 44 is pulled to move with the bearing 45 as the fulcrum.
[0053] Meanwhile, a torsion ring 46 is fixedly connected to the inner end of the rotating solenoid 47; in order to facilitate rotation, several circumferentially distributed convex rib structures are integrally formed on the outer side wall of the torsion ring 46.
[0054] During the operation, the spacing between the four target plates is pre-adjusted according to the tire size. During the adjustment, the length of adjustment of the four target plates must be the same.
[0055] Specifically, during the adjustment process, the operator rotates the rotating solenoid 47. Because the rotating solenoid 47 is threadedly connected to the pull adjustment screw 44, under the threaded pushing force of the rotating solenoid 47 and the pull adjustment screw 44, the pull adjustment screw 44, carrying the claw structure, moves towards the target frame 1. During this process, as the distance between the claw structures decreases, the claw structures gradually engage with the center of the upper, lower, left, and right sidewalls of the tire (during ADAS visual calibration, the vehicle is on the calibration platform, and the vehicle's height is raised until the tire is appropriately above the ground; this method facilitates the calibration of the vehicle's posture). In actual work, some ADAS detection methods involve vehicle-on-the-ground detection. In this case, three adjustment locking structures are designed. Specifically, the three adjustment locking structures are set at a 90-degree angle and clamped together with three claws on the top and left and right sides of the tire.
[0056] Meanwhile, the aforementioned tension adjusting screw 44 is equipped with a scale mark 441. The scale mark 441 ensures that the four tension adjusting screws 44 are pulled the same distance during operation, thus ensuring the accurate positioning of the target plate.
[0057] Example 2
[0058] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the movable card plate 42 is integrally formed with an adjustment part that is spaced apart on the upper and lower sides, and the claw structure is installed on the adjustment part.
[0059] Specifically, the aforementioned adjustment part is provided with a sliding opening, and the claw structure includes a claw plate 41 that is slidably connected in the sliding opening; a horizontal screw 43 is fixedly connected in the sliding opening, and a blocking nut 431 that is threaded on the horizontal screw 43 and blocks the outside of the claw plate 41.
[0060] During operation, the operator adjusts the claw plate 41 until it contacts the tire, then adjusts the partition nut 431 until it blocks the outside of the claw plate 41, and pulls the adjusting screw 44 in the manner described in the above embodiment to fully clamp the claw plate 41 onto the tire.
[0061] The aforementioned horizontal screw 43 is provided with scale markings. Similarly, the scale markings on the aforementioned horizontal screw 43 ensure that all jaw plates 41 are adjusted to the same displacement length during the adjustment process of the jaw plates 41.
[0062] During the adjustment process described above, the clamping is first adjusted according to the tire size. Secondly, during the adjustment process, the position of each adjustment locking structure 4 and the claw plate 41 is controlled to be the same, so that after adjustment, the target plate is still located in the center of the tire.
[0063] Example 3
[0064] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, a target plate 31 is installed at the center of the side wall of the target frame 1; specifically, the target plate 31 is slidably installed on the target frame 1.
[0065] During operation, the relative distance between the target plate 31 and the tire is adjusted in the following way: the upper and lower ends of the rear side wall of the target frame 1 are respectively fixedly connected to the slide rail 32, the slide rail 32 is provided with a limiting groove, and the top and bottom of the target plate 31 are slidably connected in the limiting groove.
[0066] Similarly, a scale mark is set at the top of the target plate 31 to control the length of movement of the target plate 31, thereby ensuring that all target plates 31 move and adjust their displacement by the same length.
[0067] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
