[0026] The present embodiment provides a road damage detection device. Compared with the prior art, the present invention transforms the existing vehicle body 1, sets a circulating transmission mechanism at the bottom of the vehicle body 1, and the circulating transmission mechanism is a chain transmission structure. The center line of the two sprockets 6 of the circulating transmission mechanism is perpendicular to the travel direction of the vehicle body 1. A circulating slide rail 2 is set outside the chain 5 of the circulating transmission mechanism. The circulating slide rail 2 is connected to the bottom of the vehicle body 1 and has the same shape as the chain 5. Several mounting plates 4 are slidably set on the circulating slide rail 2, and the mounting plates 4 are connected to the chain 5. A detection component 3 is set on the mounting plate 4, and the detection component 3 can detect the road surface when the vehicle body 1 is moving. At the same time, the driving component is connected to a sprocket 6 of the circulating transmission mechanism. When the detection is needed, the driving component can drive the chain 5 to move, drive the detection component 3 on the mounting plate 4 to move horizontally perpendicular to the moving direction of the vehicle body 1, increase the freedom of movement of the detection component 3, and expand the detection area. A control component is set in the vehicle body 1, and the control component is electrically connected to the detection component 3, and can receive data from the detection component 3 and analyze road surface defects. The present invention realizes automatic detection of road conditions by modifying the vehicle body 1, and at the same time increases the detection range of the detection component 3 through design, expands the detection area, and improves the detection efficiency.

[0027] In this embodiment, the detection component 3 can be an ultrasonic probe or a camera, etc.

[0028] like Figure 1 to Figure 2As shown, in this embodiment, at least two rollers 7 are rotatably arranged at the bottom of the mounting plate 4, and the multiple rollers 7 on the mounting plate 4 are respectively in rolling contact with the two side surfaces of the circulating slide rail 2, and the mounting plate 4 slides along the circulating slide rail 2 through the rollers 7. A connecting block 15 is arranged on the side of the mounting plate 4, and a long hole 16 is opened on the connecting block 15. The upper end of the pin body in the chain link structure passes through the long hole 16 of the connecting block 15 and is connected to the fixing part. The fixing part can be connected to the pin body by welding, or other connection methods in the prior art can be adopted. The fixing part is used to prevent the pin body from being separated from the connecting block 15. The long hole 16 is provided to facilitate the connection between the mounting plate 4 and the chain 5.

[0029] like Figures 1 to 3 As shown, a specific embodiment provided by the present invention on the basis of the first embodiment is as follows: a road damage detection device also includes a protection mechanism, the protection mechanism includes a protection shell 14, the protection shell 14 is connected to the mounting plate 4, the protection shell 14 is a hollow structure, the detection component 3 is located in the protection shell 14, the protection shell 14 is provided with a detection window 10, the detection component 3 detects the road condition through the detection window 10, a slide bar 8 is frictionally and slidingly arranged in the protection shell 14, the movement direction of the slide bar 8 is the same as the driving direction of the vehicle body 1, both ends of the slide bar 8 extend out of the protection shell 14, both ends of the slide bar 8 are provided with protection plates 9, a collision sensing element is buried in the protection plate 9, and the collision sensing element is connected to the control component.

[0030] In this embodiment, a protective shell 14 is provided, a detection component 3 is provided inside the protective shell 14, and a detection window 10 is provided on the protective shell 14. The detection component 3 detects the road conditions through the detection window 10, so that the protective shell 14 can provide preliminary protection for the detection component 3 to prevent the detection component 3 from being damaged by collision, or debris from entering the protective shell 14 to generate a short circuit risk. At the same time, a slide bar 8 is slidably provided inside the protective shell 14, and both ends of the slide bar 8 extend out of the protective shell 14, and a protective plate 9 is provided at each end of the slide bar 8, so that whether the vehicle body 1 is moving forward or backward, if there is an object that will hinder it, it will be collided and protected first. A collision sensing element is buried in the protective plate 9, and the collision sensing element is connected to the control component. When the protective plate 9 is collided, the collision sensing element will notify the control component of the information, and the control component can control the alarm unit to send an alarm to the driver to avoid collision damage to the detection component 3.

[0031] In this embodiment, a slide rod 8 is slidably arranged in the protective shell 14, and both ends of the slide rod 8 extend out of the protective shell 14, and a protective plate 9 is respectively arranged at both ends of the slide rod 8. This structural design ensures that no matter whether the protective shell 14 moves with the mounting plate 4 to the front straight section or the rear straight section of the circulating slide rail 2, it is protected by the protective plate 9 in the front and rear directions of the vehicle body 1.

[0032] like Figures 2 to 4As shown, the present invention provides a specific implementation method based on the above implementation method as follows: the bottom of the protective shell 14 is arc-shaped, the detection window 10 is opened at the arc-shaped bottom of the protective shell 14, and an arc-shaped slide 13 is provided on two opposite inner walls of the protective shell 14. The arc-shaped slide 13 is located on the left and right sides of the arc-shaped bottom of the protective shell 14. An arc-shaped guard plate 12 is slidably arranged in the arc-shaped slide 13, and the arc-shaped guard plate 12 can slide along the arc-shaped slide 13 to close or open the detection window 10. A release component is provided in the protective shell 14, and the release component is used to control the arc-shaped guard plate 12 to open or close the detection window 10.

[0033] In this embodiment, when the protective plate 9 is hit, the release assembly releases the arc-shaped protective plate 12, and the arc-shaped protective plate 12 closes the detection window 10. When the protective plate 9 is not hit, the release assembly keeps the arc-shaped protective plate 12 stationary, and the detection window 10 is open.

[0034] In this embodiment, a support frame 17 is disposed in the protective shell 14 , and the detection component 3 is disposed on the support frame 17 . The detection component 3 is disposed upside down through the support frame 17 . A rod opening 11 is disposed in the middle of the support frame 17 , and the slide rod 8 passes through the rod opening 11 .

[0035] like Figures 2 to 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: the sliding rod 8 is a rack, two arc-shaped guard plates 12 are slidably arranged on the arc-shaped slide 13, a limit rod 25 is arranged on the arc-shaped guard plate 12, two groups of release components are arranged, and the two groups of release components are transmission-connected with the sliding rod 8. When the detection window 10 is opened, the two groups of release components are respectively in contact with the two limit rods 25, and the two arc-shaped guard plates 12 are respectively limited to the front and rear of the detection window 10; when the sliding rod 8 is impacted and moved, one of the release components is disengaged from the contact with the limit rod 25, and the arc-shaped guard plate 12 slides and closes the detection window 10 under the action of gravity.

[0036] In this embodiment, two arc-shaped guard plates 12 are arranged on the arc-shaped slide 13, and a limit rod 25 is arranged on each arc-shaped guard plate 12. At the same time, two sets of release components are arranged correspondingly, and the release components correspond to the arc-shaped guard plates 12 one by one. The release components can contact the limit rods 25 on the corresponding arc-shaped guard plates 12, so that the arc-shaped guard plates 12 remain in a stationary state. When the detection window 10 is open and is not hit, the two arc-shaped guard plates 12 are respectively located in the front and rear of the detection window 10, and are restricted by the corresponding release components to remain in a stationary state. Along the moving direction of the vehicle body 1, when the protective plate 9 located in front of the protective shell 14 is hit, the release component corresponding to the arc-shaped guard plate 12 in front of the detection window 10 is separated from the contact with the limit rod 25, and the arc-shaped guard plate 12 in front of the detection window 10 slides down under the action of gravity, closing the detection window 10. Similarly, when the protective plate 9 located behind the protective shell 14 is hit, the release assembly corresponding to the arc-shaped protective plate 12 behind the detection window 10 disengages from the limit rod 25, and the arc-shaped protective plate 12 behind the detection window 10 slides down under the action of gravity, closing the detection window 10.

[0037] like Figures 2 to 4 As shown, the present invention provides a specific embodiment based on the above embodiment as follows: the release component includes a limit claw 22, a spring piece 21, a first gear 18, a second gear 19, and a third gear 20. The limit claw 22 is rotatably arranged in the protective shell 14, and a transmission rod 24 is rotatably arranged on the limit claw 22; one end of the spring piece 21 is fixed in the protective shell 14 through a fixing seat 23, and the other end is freely released. The spring piece 21 contacts the limit claw 22 to push the limit claw 22 to contact the limit rod 25 and prevent the limit claw 22 from rotating to release the arc guard plate 12, so that the arc guard plate 12 is stationary on the detection window 10 in front or behind; the first gear 18 is meshed with the sliding rod 8; the second gear 19 is coaxially connected with the first gear 18 through a one-way bearing 27, and the one-way bearing 27 is used to control the second gear 19 to rotate only in one direction with the first gear 18; the third gear 20 is rotatably arranged in the protective shell 14 and meshed with the second gear 19. A lever 26 is provided on the third gear 20, and the lever 26 is arranged along the radial direction of the third gear 20. The lever 26 contacts with the transmission rod 24. When the third gear 20 rotates, the lever 26 pushes the limit claw 22 to rotate through the transmission rod 24 to release the arc guard plate 12.

[0038] In this embodiment, Figure 3The action process of the release assembly is described in detail from the perspective of the embodiment. When the left protective plate 9 is hit, the slide bar 8 moves from left to right, driving the two first gears 18 to rotate clockwise. The second gear 19 on the left rotates clockwise with the first gear 18 under the action of the one-way bearing 27 connected to it. The third gear 20 meshing with the second gear 19 on the left will rotate counterclockwise, and the lever 26 on the third gear 20 drives the transmission rod 24 in contact with it to rotate, driving the limit claw 22 connected to the transmission rod 24 to overcome the elastic force of the spring 21 to rotate, so that the limit claw 22 on the left is out of contact with the limit rod 25 on the left arc-shaped protective plate 12, and the left arc-shaped protective plate 12 slides down along the arc slide 13 under the action of gravity, closing the detection window 10. At the same time, the second gear 19 on the right side does not rotate with the first gear 18 under the action of the one-way bearing 27 connected to it, and the first gear 18 on the right side rotates clockwise by itself. The right limit claw 22 is always in contact with the limit rod 25 on the right arc-shaped guard plate 12 under the action of the spring 21, and the right arc-shaped guard plate 12 remains stationary. Figure 3 When the protective plate 9 on the right is hit, the sliding rod 8 will move from right to left, driving the two first gears 18 to rotate counterclockwise. The second gear 19 on the left does not rotate with the first gear 18 due to the one-way bearing 27 connected thereto, and the second gear 19 on the right rotates counterclockwise with the first gear 18. The third gear 20 on the right rotates clockwise, driving the right limit claw 22 to rotate and release the right arc-shaped protective plate 12. The right arc-shaped protective plate 12 slides and closes the detection window 10 under the action of gravity.

[0039] In this embodiment, Figure 3 The perspective is described in detail. When the left and right guard plates 9 are not collided, take the release assembly on the left as an example. Because a lever 26 is added to the third gear 20, under the action of gravity, the lever 26 may drive the third gear 20 to rotate clockwise downward. When the third gear 20 on the left rotates clockwise, the second gear 19 on the left that is meshed with it will rotate counterclockwise. Because the one-way bearing 27 on the left is that when the first gear 18 rotates clockwise, the second gear 19 will rotate accordingly. Otherwise, the second gear 19 will not rotate accordingly. Therefore, the second gear 19 cannot rotate counterclockwise relative to the first gear 18. When it rotates counterclockwise relative to the first gear 18, it will be locked, thereby ensuring that the lever 26 and the transmission rod 24 remain in contact in a non-collision state. The structure on the right is the same. Once a collision occurs, the lever 26 will quickly shift the transmission rod 24, so that the limit claw 22 is out of contact with the limit rod 25, ensuring that the detection window 10 is quickly closed.

[0040] like Figures 5 to 8As shown, the present invention provides a specific embodiment based on the above embodiment as follows: the protective shell 14 is a hollow structure, and detection windows 10 are opened on both sides of the protective shell 14, the two detection windows 10 are opposite, and the detection component 3 is located between the two detection windows 10. A guide slot 33 is respectively arranged on the protective shell 14 and below the two detection windows 10. An arc-shaped guide slide is arranged in the protective shell 14, and an arc-shaped baffle 30 is slidably arranged in the guide slide. The two ends of the arc-shaped baffle 30 can be respectively passed through the two guide slots 33. 3 extends out of the protective shell 14, a linkage plate 35 is rotatably arranged at the middle part of the lower end of the arc-shaped baffle 30, and the linkage plate 35 is in a vertical state under the action of gravity, a guide rail 32 is fixedly arranged in the protective shell 14, and the length direction of the guide rail 32 is parallel to the length direction of the slide bar 8, a U-shaped block 44 is slidably arranged on the guide rail 32, and the linkage plate 35 is inserted into the U-shaped groove formed by the U-shaped block 44, and a push-out assembly is also arranged in the protective shell 14, and the push-out assembly is used to push the U-shaped block 44 to slide along the guide rail 32 and drive the arc-shaped baffle 30 to extend out of the protective shell 14.

[0041] In this embodiment, the detection component 3 is a detection element with a steering function. Detection windows 10 are provided on both opposite sides of the protective shell 14. No matter which straight section of the circulating slide rail 2 the detection component 3 moves to with the mounting plate 4, it can detect the front through different detection windows 10. In this embodiment, a guide notch 33 is provided below each of the two detection windows 10, and an arc-shaped guide slide is provided in the protective shell 14. An arc-shaped baffle 30 is slidably provided in the guide slide, and the two ends of the arc-shaped baffle 30 can extend out of the protective shell 14 through the two guide notches 33 respectively. When no collision occurs, the arc-shaped baffle 30 is at the bottom of the arc of the guide slide under the action of gravity. A linkage plate 35 is rotatably provided under the arc-shaped baffle 30, and the linkage plate 35 is in a vertical state under the action of gravity. At the same time, a guide rail 32 is provided in the protective shell 14, and the length direction of the guide rail 32 is perpendicular to the two detection windows 10. A U-shaped block 44 is slidably provided on the guide rail 32, and the U-shaped block 44 has a U-shaped groove, and the linkage plate 35 is inserted into the U-shaped groove. When the U-shaped block 44 of the pushing assembly moves along the guide rail 32, the linkage plate 35 moves upward under the push of the U-shaped block 44, driving the arc baffle 30 to move along the guide slide, extending out of the protective shell 14, and extending to the front of the detection window 10, so that the collision object will first collide with the arc baffle 30, and the arc baffle 30 protects the detection assembly 3.

[0042] like Figures 5 to 8As shown, the present invention provides a specific embodiment based on the above embodiment as follows: there are two guide rails 32, the two guide rails 32 are arranged in parallel with each other, the U-shaped block 44 is slidably arranged on the two guide rails 32, the ejection assembly includes two sliders 29, two guide plates 36, two groups of ejection springs 28, two groups of hooks and release parts, the two sliders 29 are slidably arranged on the two guide rails 32, the two sliders 29 are respectively located on both sides of the U-shaped block 44, and are fitted with the U-shaped block 44; the two guide plates 36 have the freedom to move up and down, along the length direction of the guide rails 32, the two guide plates 36 are respectively located on the outside of the two sliders 29, the guide plates 36 are located below the two guide rails 32, and a pressing block 38 is provided in the middle of the guide plate 36, and the pressing block 38 is located between the two guide rails 32, two hangers 40 are also arranged on the guide plate 36, and the two hangers 40 are symmetrically arranged on both sides of the pressure block 38; the two groups of ejection springs 28 are respectively connected to the two pressure blocks 38, and are located between the pressure blocks 38 and the slider 29 on the same side in an extruded state; each group of hook parts includes two hanging components, and the two hanging components in the same group are respectively hung with the two hangers 40 on the same guide plate 36, and the hook parts are used to fix the guide plate 36 at a set height and keep the ejection spring 28 pressed between the slider 29 and the pressure block 38; the release part is used to control one group of hook parts to release the hanger 40, so that the pressure block 38 and the ejection spring 28 on the same side of the hanger 40 fall under the action of gravity, and the arc baffle 30 is extended out of the protective shell 14 by the elastic force of the ejection spring 28 on the other side.

[0043] In this embodiment, Figure 8Described from a perspective, four guide posts 39 are arranged at the bottom of the protective shell 14. The four guide posts 39 are arranged in groups of two and are respectively located in front of and behind the linkage plate 35. Two through holes are arranged on the guide plates 36 located in front of and behind the linkage plate 35. The two guide posts 39 in the same group pass through the two through holes on the same limit plate respectively, so that the guide plate 36 can only have the freedom to move up and down. Two mutually spaced and parallel guide rails 32 are arranged in the protective shell 14, and the guide plate 36 is located below the two guide rails 32. A pressure block 38 and two hangers 40 are arranged on each guide plate 36. The pressure block 38 is located in the middle of the guide plate 36. The two hangers 40 are arranged on the left and right sides of the pressure block 38 and are symmetrical with respect to the pressure block 38. A ejection spring 28 is arranged on the side of each pressure block 38 facing the linkage plate 35. A hooking assembly is arranged beside each hanger 40. The two hooking assemblies located in front of the linkage plate 35 form a group of hooking parts, and the two hooking assemblies located behind the linkage plate 35 form another group of hooking parts. Two sliders 29 are slidably arranged on the two guide rails 32. The two sliders 29 are respectively located on the front and rear sides of the U-shaped block 44, and one side of the slider 29 can contact the U-shaped block 44, and the other side of the slider 29 can contact the ejection spring 28. When there is no collision, the two groups of hooking parts are kept hooked with the hanger 40, and the pressing blocks 38 at the front and rear of the linkage plate 35 are located at the same height as the slider 29. At this time, the ejection springs 28 on the pressing blocks 38 are pressed against the slider 29 on the same side in a compressed state. Because the compression amount of the two ejection springs 28 is the same, the U-shaped block 44 remains in a balanced state and cannot push the arc baffle 30 to move out of the protective shell 14. At the same time, with this structural design, when the vehicle body 1 brakes suddenly, the two ejection springs 28 can play a buffering role, and the arc baffle 30 can also return to its position quickly under the action of the two ejection springs 28, so as to prevent the arc baffle 30 from being affected by the sudden brake and causing a hard collision. When a collision occurs, the release part selects to control a group of hook parts to release the hanger 40, so that the guide plate 36 and the pressing block 38 connected to the released hanger 40 slide downward under the action of gravity, so that the ejection spring 28 on one side of the linkage plate 35 is evacuated, and under the elastic force of the ejection spring 28 on the other side, the U-shaped block 44 moves along the guide rail 32, thereby pushing the arc baffle 30 through the guide slot 33 to extend out of the protective shell 14 and extend to the front of the detection window 10 to protect the detection component 3.

[0044] like Figures 5 to 8As shown, a specific implementation method provided by the present invention on the basis of the above implementation method is as follows: a hanging hole is provided on the outer side of the hanger 40, and the hanging assembly includes a hook 42, a fixing plate 41, and a clamping spring 43. The middle part of the hook 42 is rotatably connected to the protective shell 14. A hook 42 is provided next to the hanging hole of each hanger 40, and the hook 42 is used to be hung with the hanging hole; a fixing plate 41 is provided next to each hook 42, and the fixing plate 41 is connected to the protective shell 14; one end of the clamping spring 43 is connected to the fixing plate 41, and the other end is connected to the hook 42, and the clamping spring 43 is used to pull the hook 42 to rotate and hook the hanger 40.

[0045] In this embodiment, the hook assembly includes a hook 42, a fixing plate 41 and a clamping spring 43. The middle part of the hook 42 is rotatably connected to the protective shell 14. Since the lower end of the hook 42 has a hook body, the lower end of the hook 42 is heavier and the upper end is relatively lighter, so that the hook 42 is in a vertical state under the action of gravity. In this state, the hook body of the hook 42 just extends into the hanging hole of the hanger 40. A fixing plate 41 is set next to each hook 42. One end of the clamping spring 43 is connected to the fixing plate 41, and the other end of the clamping spring 43 is connected to the hook 42 closer to the hook body. The clamping spring 43 will pull the hook body end of the hook 42 to rotate toward the hanging hole of the hanger 40, so that the hanging is more stable.

[0046] like Figures 6 to 8 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: there are two sliding rods 8, the two sliding rods 8 are arranged at an interval, and the ends of the two sliding rods 8 on the same side are connected by the same protective plate 9, the release part includes four push blocks 34, two push blocks 34 are arranged on each of the sliding rods 8, and the two hooks 42 on the same side of the sliding rod 8 are arranged between the two push blocks 34 on the sliding rod 8, and the push block 34 is used to push the hook 42 to rotate and disengage from the hanging part 40 when passing by the hook 42.

[0047] In this embodiment, Figure 6The two detection windows 10 on the protective shell 14 are respectively located in front and rear of the moving direction of the vehicle body 1, so the moving direction of the vehicle body 1 is described as the front-to-back direction. Two slide bars 8 are provided. When there is no external force, the two slide bars 8 remain stationary under the action of friction; when encountering external force collision, the two slide bars 8 can move in the front-to-back direction. The two slide bars 8 are respectively provided on the left and right sides of the arc-shaped baffle 30, and at the same time, each side of the left and right sides of the arc-shaped baffle 30 has two hanging components, and the two push blocks 34 on the same slide bar 8 are respectively located next to the two hanging components on the same side, and the two hanging components are located between the two push blocks 34. When the front side of the slide bar 8 is hit, the slide bar 8 moves from front to back under the external force of the collision. The push block 34 closer to the front will pass the front hook assembly as the slide bar 8 moves, pushing the front hook assembly to disengage from the hook hole, so that the pressing block 38 in front of the linkage plate 35 will fall, and the ejection spring 28 behind the linkage plate 35 will push the U-shaped block 44 forward, and the arc baffle 30 will extend from the front. The push block 34 closer to the rear will move away from the rear hook assembly as the slide bar 8 moves, so the pressing block 38 behind the linkage plate 35 remains stationary. Similarly, when the rear is hit, the arc baffle 30 will extend from the rear.

[0048] In this embodiment, a slope is provided on the push block 34, and the end of the hook 42 farther away from the hook body contacts the slope. As the slide rod 8 moves, the slope pushes the hook 42 to rotate away from the slide rod 8, thereby disengaging the hook 42 from the hanging hole.

[0049] like Figures 5 to 8 As shown, the present invention provides a specific implementation mode based on the above implementation mode as follows: a buffer spring 31 is arranged inside the protective shell 14 and below the guide plate 36 .

[0050] In this embodiment, a buffer spring 31 is disposed below the guide plate 36 to play a buffering role and prevent the guide plate 36 from hard collision with the protective shell 14 and causing damage.

[0051] like Figures 5 to 8As shown, a specific embodiment of the present invention provided on the basis of the above-mentioned embodiment is as follows: a V-shaped rod 37 is rotatably arranged under each pressure block 38, and the V-shaped rod 37 includes an intersecting long rod and a short rod, and the intersection of the long rod and the short rod is rotatably connected to the protective shell 14, the short rod is located under the pressure block 38, with the linkage plate 35 as a dividing line, and the long rod is located under the slider 29 on the opposite side, and a support block 45 is provided on the lower side of the long rod, and the support block 45 is used to support the V-shaped rod 37 and keep the short rod under the pressure block 38, and the long rod is kept under the slider 29 on the opposite side, and a limit block 46 is provided at the lower end of the slider 29. When the pressure block 38 falls, the arc baffle 30 slides out of the protective shell 14 under the elastic force of the ejection spring 28 on the opposite side, and the falling pressure block 38 presses the V-shaped rod 37 to rotate, so that the long rod contacts the limit block 46 of the slider 29 on the opposite side, restricting the slider 29 from returning to its original position, so as to prevent the arc baffle 30 from falling back into the protective shell 14.

[0052] In this embodiment, Figure 8 From a perspective of the present invention, when the front pressure block 38 and the guide plate 36 fall down to a certain height, the front guide plate 36 will press the short rod below it, thereby driving the V-shaped rod 37 to rotate. The ejection spring 28 connected to the falling pressure block 38 is separated from the contact with the slider 29, so that the ejection spring 28 on the rear side pushes the arc baffle 30 to quickly extend out of the protective shell 14. When the front guide plate 36 falls to the lowest position, the long rod of the V-shaped rod 37 just rotates to the rear side of the limit block 46 of the opposite slider 29 and contacts the limit block 46 on the opposite slider 29, thereby preventing the slider 29 from returning to the original rear position and maintaining the arc baffle 30 in the extended protective state.
