Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a vehicle climbing detection device based on a segmentation model. Background Art

[0002] The deep learning model can automatically learn the characteristics of product images and use a detection method based on the deep learning model, namely the segmentation model, to detect product images. According to the detection results, the product can be divided into unqualified (defective) areas and categories. During the vehicle climbing test, a climbing detection device is required. The detection device under the existing technology uses a camera to capture images and then inputs the image to be detected into the trained segmentation model to detect and output the defect category probability value of each pixel in the image to be detected.

The driverless vehicle climbing test device has a test pad detachably arranged on the test board, and the test pad can have different test surfaces. By replacing the test pad, the driverless vehicle climbing grade test on different test surfaces can be carried out more conveniently, and can greatly save labor costs and time costs.

In view of this, we propose a vehicle climbing detection device based on a segmentation model. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0029] A vehicle climbing detection device based on a segmentation model includes a base 1, a ramp plate 11 is hinged on the top of the base 1, and a hydraulic cylinder 12 is symmetrically hinged on the top of the base 1 near the left side and near the front and rear sides. The end of the piston rod of the hydraulic cylinder 12 is hinged to the bottom of the ramp plate 11 to drive the ramp plate 11 to rotate.

[0030] Specifically, the top of the base 1 is fixedly connected to the housing 13 by bolts, and a limiting groove 14 is provided at the front end of the housing 13 to limit the moving direction of the limiting plate 18.

[0031] Specifically, a rotating motor 15 is fixedly connected to the top of the housing 13 by bolts to drive the threaded rod 16 to rotate. The output shaft of the rotating motor 15 is coaxially connected to the threaded rod 16. The bottom end of the threaded rod 16 passes through the top of the housing 13 to drive the slider 17 to move.

[0032] Specifically, the threaded rod 16 is threadedly connected to a slider 17 , and the slider 17 is slidably connected to the inner wall of the housing 13 to drive the limiting plate 18 to move.

[0033] Specifically, the front end of the slider 17 is fixedly connected to the limit plate 18 by bolts, and the left and right surfaces of the limit plate 18 are respectively in contact with the left and right surfaces of the inner wall of the limit slot 14 to drive the mounting bracket 21 to move.

[0034] As a preferred embodiment of this embodiment, a buffer mechanism 2 is provided above the base 1, and the buffer mechanism 2 includes a mounting frame 21. The top of the mounting frame 21 is fixedly connected to the bottom of the limiting plate 18 by bolts, and the right surface of the mounting frame 21 is fixedly connected to a damping liquid container 22 by bolts, and the damping liquid container 22 is filled with damping liquid.

[0035] Specifically, a piston 23 is slidably connected to the inner wall of the damping liquid container 22. The piston 23, the damping liquid container 22 and the piston rod 24 form a damping structure. The viscosity of the damping liquid is utilized to achieve high damping effect, thereby improving the vibration isolation efficiency and reducing vibration. The left end of the piston 23 is fixedly connected to the piston rod 24 by a bolt to drive the piston 23 to move.

[0036] Specifically, the left end of the piston rod 24 passes through the left end of the damping fluid container 22 and the left end of the mounting frame 21 in sequence and is fixedly connected to the mounting plate 25 by bolts. The airbag 26 is fixed to the left surface of the mounting plate 25 by glue to cushion the collision.

[0037] Specifically, the right side surface of the mounting plate 25 is symmetrically fixed with a limiting rod 27 near the front and rear sides by bolts. The right end of the limiting rod 27 passes through the right end of the mounting frame 21 and is welded and fixed to a limiting plate 28. A spring 29 is provided on the circumferential outer wall of the limiting rod 27. The right end of the spring 29 is fixedly connected to the left side surface of the limiting plate 28 corresponding to its position, so as to limit the position of the mounting frame 21.

[0038] Furthermore, an adjustment mechanism 3 is provided on the top of the base 1, and the adjustment mechanism 3 includes an adjustment motor 31, which is used to drive the adjustment threaded rod 32 to rotate. The adjustment motor 31 is fixedly connected to the top of the base 1 by bolts, and the output shaft of the adjustment motor 31 is coaxially connected to the adjustment threaded rod 32, which is used to drive the movable plate 33 to move.

[0039] It should be added that the adjusting threaded rod 32 is threadedly connected to a movable plate 33, which is used to drive the cylinder 34 to move. The bottom of the movable plate 33 is in contact with the top of the base 1, and the top of the movable plate 33 is fixedly connected to the cylinder 34 by bolts, which is used to drive the wireless camera 35 to move. The piston rod end of the cylinder 34 is fixedly connected to the wireless camera 35 by bolts, which is used to take images and input the image to be detected into the trained segmentation model, so as to detect and output the defect category probability value of each pixel in the image to be detected.

[0040] It is worth mentioning that the structure and working principle of the wireless camera 35 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0041] During use, the tester first controls the piston rods of the two hydraulic cylinders 12 to extend, thereby driving the ramp plate 11 to rotate. When the inclination angle of the ramp plate 11 reaches the specified inclination angle, the tester stops controlling the piston rods of the two hydraulic cylinders 12 to extend. Then, the vehicle is driven to the top of the ramp plate 11 and the rotary motor 15 is turned on. The rotary motor 15 drives the threaded rod 16 to rotate, thereby driving the slider 17 to move downward, thereby driving the limit plate 18 to move downward, and thus driving the mounting bracket 21 to move downward.

[0042] When the bottom of the mounting bracket 21 is in contact with the top of the base 1, the rotating motor 15 is turned off. When the vehicle slides down the slope, the vehicle moves downward until the rear end of the vehicle hits the left surface of the airbag 26. The airbag 26 first cushions the collision and then drives the mounting plate 25 to move rightward, thereby driving the two limit rods 27 to move rightward, thereby driving the two limit plates 28 to move rightward, thereby stretching the two springs 29.

[0043] During this process, the mounting plate 25 drives the piston rod 24 to move to the right, thereby driving the piston 23 to move to the right, thereby compressing the damping fluid in the damping fluid container 22. The viscous resistance of the damping fluid in the damping fluid container 22 is used to attenuate the kinetic energy of the vibration of the device, so that the mechanical energy of the vibration is converted into frictional heat energy, thereby consuming the vibration force and cushioning the collision.

[0044] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
