[0001] The utility model belongs to the technical field of road damage detection, and particularly relates to a road surface damage collection device. Background Art

[0002] The road inspection vehicle integrates and applies modern information technologies, uses a motor vehicle as a platform, and integrates optoelectronic, IT, and 3S technologies. Under the normal driving state of the vehicle, it can automatically complete the data collection, analysis, classification, and storage of road surface images, road surface shapes, three-dimensional images of road facilities, flatness, and road geometric parameters.

[0003] For the detection of road surfaces, existing inspection vehicles generally set a road surface damage collection device on the roof. The road surface damage collection device mainly collects transverse cracks, longitudinal cracks, puddles, crazing, potholes, etc. on the road surface, and analyzes, classifies, and stores the collected information; the road surface damage collection device mainly completes information collection through a camera. When in use, the angle of the camera lens irradiating the road surface needs to be adjusted. The existing camera angle adjustment is manual adjustment, and the adjustment angle range is limited. When the inspection vehicle is driving for inspection, if it is found that the camera angle needs to be adjusted by observing the road surface image, the vehicle needs to stop to adjust. After adjustment, it is necessary to return to the vehicle to observe whether the image is appropriate, and the operation is relatively troublesome, which affects the detection efficiency of the inspection vehicle. On the other hand, for some cameras set by an electric control pan-tilt, due to the small angle adjustment motor, when transferred to the road surface damage collection device, the position locking effect achieved by motor self-locking is not good due to the large load, resulting in a change in the camera angle when the vehicle jolts. Content of the Utility Model

[0004] The purpose of the utility model is to provide a road surface damage collection device, which has the advantage of being convenient to adjust the downward viewing angle of the camera, and solves the problem that the operation of adjusting the downward viewing angle of the existing camera is relatively troublesome.

[0005] The utility model adopts the following technical scheme: A road surface damage collection device includes a housing. An installation box is arranged inside the housing.

A camera is rotatably connected between the two sliders. A driving device is arranged in the housing at the right side of the slider. The output ends of the driving device are respectively connected to each slider. A limiting mechanism is arranged between each slider and the housing.

[0009] Further, a sliding plate is slidably arranged in the left - right direction at the position corresponding to the slider on the upper end surface of the installation box, the slider is slidably arranged in a chute formed along the length direction of the sliding plate, the limiting plate is slidably connected to the inner side wall of the housing in the left - right direction, a guide block is fixedly arranged on the outer side surface of the limiting plate, a guide groove is formed in the inner side wall of the housing in the left - right direction, and the guide block is located in the guide groove; a first spring is fixedly arranged on the left side surface of the slider, and the left end of the first spring is fixedly arranged on the right side surface of an end plate fixedly arranged with the limiting plate.

[0010] Further, a plurality of groups of electromagnets are uniformly arranged on the lower end surface of the housing, and a switch button is installed on the installation box.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments:

[0027] Please refer to Figure 1-7 , the pavement damage collection device of the present utility model includes a housing 1. An installation box 2 is arranged inside the housing 1. Two sliders 3 are slidably arranged on the upper end surface of the installation box 2 in the left-right direction. The two sliders 3 are symmetrically arranged front and back. A camera 4 is rotatably connected between the two sliders 3. A driving device is arranged inside the housing 1 to the right of the slider 3. The output end of the driving device is connected to each slider 3. A limiting mechanism is arranged between each slider 3 and the housing 1. The limiting mechanism is used to force the left end of the camera 4 to rotate downward when the camera 4 slides to a set position to the left, so as to realize the depression angle adjustment.

[0028] During use, the housing 1 is fixed on the roof of the detection vehicle. Under the normal driving state of the detection vehicle, the information of the road surface can be collected through the camera 4, including transverse cracks, longitudinal cracks, puddles, crazing, potholes, etc. When it is necessary to adjust the depression angle of the camera 4, the driving device drives the two sliders 3 to slide to the left. The two sliders 3 drive the camera 4 to slide out of the housing 1. When the camera 4 slides to a set position to the left, the driving device continues to push the camera 4 to slide to the left. At this time, the camera 4 rotates downward under the action of the limiting mechanism, so that the camera 4 can photograph the road surface, which is convenient for collecting road surface information. Under the action of the limiting mechanism, the depression angle rotation angle of the camera 4 is from zero degree to ninety degrees; it is convenient for the user to make adaptive adjustments according to different vehicle models and the installation position of the installation box 2.

[0029] In this embodiment, a rotating shaft 5 is rotatably connected inside each slider 3. The inner ends of the two rotating shafts 5 are fixedly arranged with the camera 4. The camera 4 is rotatably connected to the two sliders 3 through the two rotating shafts 5 respectively; a connecting rod 6 is fixedly arranged at the outer end of the rotating shaft 5. A pin shaft 7 is fixedly arranged at the end of the connecting rod 6 away from the rotating shaft 5; during the use process, when the driving device drives the two sliders 3 to slide to the left, the limiting mechanism changes the movement track of the pin shaft 7 by restricting the pin shaft 7, and then drives the rotating shaft 5 to rotate through the connecting rod 6, and the rotating shaft 5 drives the camera 4 to rotate, so as to realize the purpose of the camera 4 rotating to the left.

[0030] In this embodiment, the limiting mechanism includes a limiting plate 8 arranged between the slider 3 and the inner side wall of the housing 1. A limiting groove is opened on the inner side wall of the limiting plate 8. The pin shaft 7 is located in the limiting groove; when the two sliders 3 slide to the left, the pin shaft 7 is driven to move in the limiting groove of the limiting plate 8 through the rotating shaft 5 and the connecting rod 6. The movement track of the pin shaft 7 changes, and then the rotating shaft 5 is driven to rotate through the connecting rod 6, and the rotating shaft 5 drives the camera 4 to rotate, so as to realize the purpose of the camera 4 rotating downward.

[0031] In this embodiment, the limiting groove includes an upper horizontal groove 9, a lower horizontal groove 10, and an inclined groove 11. The top end of the inclined groove 11 communicates with the upper horizontal groove 9, and the bottom end of the inclined groove 11 communicates with the lower horizontal groove 10. The upper end of the inclined groove 11 inclines to the left. When the two sliding grooves 13 slide to the left, the pin shaft 7 first slides to the left in the lower horizontal groove 10. At this time, the connecting rod 6 moves to the left while maintaining a vertical state, so that the rotating shaft 5 remains stationary in the slider 3, and the camera 4 slides to the left under the drive of the two sliders 3. When the pin shaft 7 enters the inclined groove 11, the speed of the pin shaft 7 moving to the left lags behind the speed of the rotating shaft 5 moving to the left, causing the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the camera 4 to rotate downward, achieving the purpose of adjusting the angle of the camera 4 for detecting the road surface. When the pin shaft 7 moves into the upper horizontal groove 9, the pin shaft 7 drives the camera 4 to rotate downward by ninety degrees through the connecting rod 6 and the rotating shaft 5. When the pin shaft 7 is in the inclined groove 11 between the lower horizontal groove 10 and the upper horizontal groove 9, the angle of the camera 4 rotating downward is between zero degrees and ninety degrees. The angle of the camera 4 rotating downward can be adjusted to any angle value between zero degrees and ninety degrees through the driving device. Adjust according to the actual situation for convenient use.

[0032] In order to achieve the purpose of extending the leftward sliding distance of the camera 4, in this embodiment, a sliding plate 12 is slidably arranged in the left-right direction at a position corresponding to the slider 3 on the upper end surface of the mounting box 2. The slider 3 is slidably arranged in the left-right direction in a chute 13 opened along the length direction of the sliding plate 12. The limiting plate 8 is slidably connected to the inner side wall of the housing 1 in the left-right direction. A guiding block 14 is fixedly arranged on the outer side surface of the limiting plate 8. A guiding groove 15 is opened in the inner side wall of the housing 1 in the left-right direction. The guiding block 14 is located in the guiding groove 15. A first spring 16 is fixedly arranged on the left side surface of the slider 3. The left end of the first spring 16 is fixedly arranged on the right side surface of an end plate 17 fixedly arranged with the limiting plate 8. During use, the driving device drives the two sliders 3 to slide leftward. The two sliders 3 push the limiting plate 8 to slide leftward through the first spring 16 and the end plate 17. When the slider 3 slides to the left side wall of the chute 13 of the sliding plate 12, the slider 3 pushes the sliding plate 12 to slide leftward. The leftward sliding of the limiting plate 8 drives the guiding block 14 to slide in the guiding groove 15. When the guiding block 14 slides to the left end of the guiding groove 15, the guiding groove 15 restricts the movement of the guiding block 14, thereby causing the limiting plate 8 to stop moving leftward. At this time, the slider 3 continues to slide leftward, causing the pin shaft 7 to slide in the limiting groove. When the pin shaft 7 enters the inclined groove 11, the pin shaft 7 drives the rotating shaft 5 to rotate through the connecting rod 6, thereby driving the camera 4 to rotate, so that the camera 4 rotates leftward after sliding leftward by a set distance, achieving the purpose of adjusting the detection angle of the camera 4. The setting of the sliding plate 12 realizes the adjustment of the left and right positions of the camera 4 on the roof of the detection vehicle, enabling the present utility model to adapt to different roof lengths caused by different vehicle models and avoiding the vehicle roof from blocking the picture during shooting. At the same time, the setting of the sliding plate 12 can completely accommodate the camera 4 in the housing 1, providing good protection for the camera 4 during the non-working time when the camera 4 is not in use.

[0033] In order to achieve the purpose of timely resetting the sliding plate 12, in this embodiment, a second spring 18 is arranged between the right end of the sliding plate 12 and the mounting box 2. When the two sliders 3 slide rightward, the second spring 18 pulls the sliding plate 12 to slide rightward, enabling the sliding plate 12 to be timely reset in the housing 1. The right end of the second spring 18 is fixedly arranged with the mounting box 2 through a fixing block 22.

[0034] In order to achieve the purpose of limiting the sliding plate 12 when it slides left and right on the mounting box 2, in this embodiment, the sliding plate 12 is slidably arranged in a sliding groove 19 opened in the left-right direction on the upper end surface of the mounting box 2. Stopping blocks 20 are fixedly arranged on the front and rear side surfaces of the sliding plate 12. Limiting notches 21 are opened on the front side wall and the rear side wall of the sliding groove 19. The stopping blocks 20 are located in the corresponding limiting notches 21. When the sliding plate 12 slides left and right on the mounting plate, the sliding plate 12 drives the stopping blocks 20 to slide in the limiting notches 21. The length of the limiting notches 21 is the left-right movement range of the sliding plate 12.

[0035] In order to achieve the purpose of facilitating the fixation of the housing 1 to the roof of the inspection vehicle, in this embodiment, a plurality of groups of electromagnets 23 are uniformly arranged on the lower end surface of the housing 1, and a switch button 24 is installed on the installation box 2. The housing 1 is placed on the roof of the inspection vehicle. When the switch button 24 is turned on, the electromagnets 23 generate magnetic force to adsorb the roof, so that the housing 1 is fixed to the roof of the inspection vehicle through the electromagnets 23. When disassembling, turn off the switch button 24, and the magnetic force of the electromagnets 23 disappears. At this time, the housing 1 can be removed from the roof of the inspection vehicle.

[0036] In this embodiment, the driving device includes an electric telescopic rod 25 fixedly arranged on the inner side wall of the housing 1. The output end of the electric telescopic rod 25 is fixedly arranged with two sliders 3 through a connecting plate 26. When the electric telescopic rod 25 moves, it drives the two sliders 3 to move left and right on the upper end surface of the installation box 2 through the connecting plate 26. And after the camera 4 rotates downward, through the cooperation of the pin shaft 7 and the limiting groove, the depression angle of the camera 4 can be locked synchronously after the position of the electric telescopic rod 25 is locked. This effectively avoids the drawback that in some existing cameras 4 arranged through an electric control pan-tilt, due to the poor position locking effect achieved when the angle adjustment motor is self-locked, the angle of the camera 4 changes when the vehicle jolts.

[0037] In this embodiment, a bracelet 27 is hinged to the upper end surface of the housing 1, which facilitates the movement of the housing 1 through the bracelet 27.

[0038] During the use of the present utility model: The housing 1 is fixed on the roof of the inspection vehicle. The on-off of the electromagnets 23 can be controlled through the switch button 24, which is convenient for fixing and disassembling. Under the normal driving state of the inspection vehicle, the camera 4 can collect information on the road surface, including transverse cracks, longitudinal cracks, puddles, crazing, potholes, etc. When detection is required, the driving device drives the two sliders 3 to slide to the left. The two sliders 3 push the limiting plate 8 to slide to the left through the first spring 16 and the end plate 17. When the slider 3 slides to the left side wall of the chute 13 of the sliding plate 12, the slider 3 pushes the sliding plate 12 to slide to the left. The limiting plate 8 sliding to the left drives the guide block 14 to slide in the guide groove 15. When the guide block 14 slides to the left end of the guide groove 15, the guide groove 15 restricts the movement of the guide block 14, thereby causing the limiting plate 8 to stop moving to the left. At this time, the slider 3 continues to slide to the left, causing the pin shaft 7 to slide in the limiting groove. When the pin shaft 7 enters the inclined groove 11, the pin shaft 7 drives the rotating shaft 5 to rotate through the connecting rod 6, and then drives the camera 4 to rotate, so that the angle of the camera 4 rotates to an angle suitable for detecting the road surface, so that the camera 4 rotates to the left after sliding a set distance to the left, achieving the purpose of adjusting the detection angle of the camera 4.

[0039] The fixing method of the housing 1 to the roof of the inspection vehicle can adopt the installation and fixing method of the existing roof warning device. For example, it can be fixed by the cooperation of a buckle and a fixing bolt, or by using a permanent magnet or an electromagnet 23. This belongs to the conventional technology in this field and will not be elaborated here. The electromagnet 23 can be powered by the cooperation of the storage battery built in the installation box 2 and the vehicle-mounted battery.
