TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile chassis detection, and particularly relates to an automobile chassis gap detection device and system. BACKGROUND

[0002] The automobile chassis gap detector is a professional equipment for detecting the automobile chassis, which can quantify the looseness of each part of the chassis, so as to find potential safety hazards. The automobile chassis gap detector can simulate the impact force on the chassis when the vehicle is in a bump and a steering, and quantitatively measure the gap values of each connecting part of the chassis in the up-down (vertical) and left-right (horizontal) directions through a mechanical device and a sensor.

[0003] In the prior art, when the chassis of the automobile is detected, the automobile needs to be driven to the detection device. However, the surface of the detection device is usually flat, and only the pattern on the surface of the detection device increases the friction with the wheels. In the detection, the body needs to be shaken. Once the friction between the tire and the surface of the detection device is reduced, the tire may slip when it is shaken, which is easy to cause the tire to slip out of the detection device, thereby affecting the detection result of the automobile chassis and easily causing safety hazards.

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 - Figure 3As shown, the present invention proposes a vehicle chassis clearance detection device, including a support plate 1, a reserved groove at the top of the support plate 1, a loading shell 2 installed in the reserved groove, a hydraulic system 3 installed inside the loading shell 2, and a detection plate 4 at the top of the loading shell 2. The detection plate 4 is connected to the hydraulic system 3. When the vehicle tires drive onto the detection plate 4, the hydraulic system 3 can be activated to drive the detection plate 4 to move laterally or longitudinally, thereby detecting the clearance existing in the vehicle chassis.

[0020] like Figure 1 , Figure 2 and Figure 8 As shown, the vehicle chassis clearance detection device also includes an adjustment assembly for controlling the height of the pallet 1. The adjustment assembly includes a base plate 5, which is located at the bottom of the pallet 1. The adjustment assembly also includes a first hydraulic rod 6, which is fixed to the top of the base plate 5. A first round rod 8 is fixed to the output end of the first hydraulic rod 6. When the height of the pallet 1 needs to be adjusted, the first hydraulic rod 6 can be activated, pushing the first round rod 8 to one side via hydraulic pressure. A first support rod 7 is rotatably connected to the top of the base plate 5, and a second support rod 9 is rotatably connected to the outer wall of the first round rod 8. The first support rod 7 and the second support rod 9 are rotatably connected via a short rod. When the first round rod 8 moves, it will cause the bottom of the second support rod 9 to move to one side via the connection of the short rod, and simultaneously the top of the second support rod 9 will also move downwards. A first sliding frame 10 is fixedly connected to the top end. A first round rod 8 is slidably disposed on the inner wall of the first sliding frame 10. The first round rod 8 will slide on the inner wall of the first sliding frame 10, and the first sliding frame 10 will also limit the movement of the first round rod 8. A second round rod 12 is fixedly connected to the top end of the first support rod 7. A second sliding frame 11 is fixedly connected to the bottom end of the support plate 1. The second round rod 12 is slidably disposed on the inner wall of the second sliding frame 11. A second support rod 9 is rotatably connected to the bottom end of the support plate 1. When the second support rod 9 moves downward, it will drive the support plate 1 to move downward, and at the same time squeeze the first support rod 7 downward. When the first support rod 7 moves downward, it can be limited by the second round rod 12 sliding in the second sliding frame 11, so as to cause the support plate 1 to move downward in a straight line until the support plate 1 is adjusted to the height of the car, so that the car can be driven onto the support plate 1.

[0021] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the pallet 1 has a slot 14 inside, and a fixing component is installed inside the slot 14 to limit the position of the wheels on the detection plate 4. The fixing component includes a drive motor 13, which is fixed to the bottom of the pallet 1. The output end of the drive motor 13 is fixed to a first gear 15. When the four sets of tires of the car drive onto the pallet 1, the tires will pass through the gap between the two sets of push blocks 20 and contact the inclined plate 25. After the tires drive onto the inclined plate 25, they will drive to the top of the detection plate 4. When all four sets of tires are on the four sets of detection plates 4, the drive motor 13 can be started, causing the drive motor 13 to drive the first gear 15 to rotate. The first gear 15 is located inside the slot 14, and a limit strip 17 is fixed to the bottom of the inner wall of the slot 14. A first rack 16 meshes with one side of the wheel 15. When the first gear 15 rotates, it drives the first racks 16 on both sides to move towards the center. Two sets of limiting strips 17 can limit the movement of the two sets of first racks 16. The first racks 16 are slidably disposed inside the limiting strips 17. A horizontal bar 18 is fixedly connected to one end of the first rack 16. A vertical bar 19 is fixedly connected to the top of the horizontal bar 18. A push block 20 is fixedly connected to the top of the vertical bar 19. The push block 20 is arc-shaped. When the first rack 16 moves, it drives the horizontal bar 18 and the two sets of vertical bars 19 to move together. When the two sets of vertical bars 19 move, they drive the two sets of push blocks 20 to move. The arc shape on one side of the push block 20 can lift the inclined plate 25. A groove is opened at the top of the support plate 1. The vertical bar 19 is slidably disposed. The first rack 16, the limiting strip 17, and the crossbar 18 are each provided in two sets, and are centrally symmetrically distributed on both sides of the first gear 15. A vertical plate 24 is fixed to the top of the support plate 1, and an inclined plate 25 is rotatably connected to the top of the vertical plate 24 via a rotating shaft. A mounting groove is opened on one side of the push block 20, and a first roller 21 is rotatably connected to the bottom of the inner wall of the mounting groove. The first roller 21 is located on one side of the bottom of the inclined plate 25. When the push block 20 moves to one side of the inclined plate 25, the first roller 21 will first contact the bottom of the inclined plate 25. Since the first roller 21 is located at the bottom of the inclined plate 25 and is partially embedded in the groove, the inclined plate 25 can be lifted by the contact between the first roller 21 and the inclined plate 25. Multiple sets of second rollers 22 are rotatably connected to the inner wall of the mounting groove. Multiple sets of second rollers 22 are positioned on top of the first roller 21. The tilted plate 25, after being lifted, contacts these second rollers 22. In conjunction with the movement of the push block 20, the tilted plate 25 slides off the second rollers 22, facilitating its flipping until its top is flipped to one side of the car wheel. The push block 20 is positioned on one side of the tilted plate 25. Two sets of vertical plates 24 and two sets of tilted plates 25 are symmetrically distributed on both sides of the detection plate 4. Since the two sets of first racks 16 move simultaneously towards the center, they drive another set of horizontal bars 18, two sets of vertical bars 19, and the push block 20 to move towards the center. The four sets of push blocks 20 can then lift the two sets of tilted plates 25 upwards, fixing the two sides of the tire in place.To prevent the tire from slipping off the inspection plate 4 during inspection.

[0022] like Figure 1 , Figure 7 and Figure 8 As shown, one end of the pallet 1 is provided with a guiding component for guiding the vehicle's trajectory. The guiding component includes a connecting plate 27, which is fixed to one side of the pallet 1. One side of the top of the connecting plate 27 is inclined. When a car needs to drive onto the pallet 1, the connecting plate 27 on one side of the pallet 1 allows the car wheels to drive onto the connecting plate 27 via the inclined top of the connecting plate 27 and move towards the top of the pallet 1. A guide plate 28 is fixed to the top of the connecting plate 27. The guide plate 28 is arc-shaped. By setting the arc-shaped guide plate 28, the two rows of wheels of the car can be guided, allowing the car wheels to be accurately guided onto the pallet 1. The guide plate 28 is located on one side of a set of push blocks 20 to prevent the push rods from interfering with the tires. Multiple sets of round rollers 29 are rotatably connected to the inner wall of the guide plate 28. Multiple sets of airbags 30 are fixed inside the guide plate 28. Multiple sets of circular rollers 29 are staggered. Since the circular rollers 29 are provided on one side of the guide plate 28, the wheels can be guided to pass over the circular rollers 29 and avoid scratching. At the same time, multiple sets of airbags 30 are provided between the multiple sets of circular rollers 29. The airbags 30 can protect the wheels in advance and prevent hard scratches when the wheels come into contact with the circular rollers 29. Two sets of side plates 31 are fixed to both sides of the support plate 1. The top of one side of the side plate 31 is inclined. By setting two sets of side plates 31 on both sides of the support plate 1, the two sides of the side plates 31 are limited, which effectively prevents the wheels from tilting when they drive into the middle of the support plate 1. The top of the detection plate 4 is provided with a groove and anti-slip texture 26. By providing a groove at the top of the detection plate 4, the wheels can be positioned in the detection plate 4 when they drive into the groove. By providing anti-slip texture 26 on the detection plate 4, the friction between the detection plate 4 and the wheels can be increased.

[0023] like Figure 8 , Figure 9 and Figure 10As shown, a lighting component for improving local lighting effect is provided on one side of the pallet 1. The lighting component includes a first sleeve 32, which is fixed to one side of the side plate 31. A direct light 33 is fixed inside the first sleeve 32. Multiple sets of direct lights 33 and first sleeves 32 are provided and are distributed in parallel on one side of the side plate 31. When it is necessary to inspect the chassis of the car, the direct lights 33 can be turned on. Since multiple sets of direct lights 33 are distributed in parallel, the chassis 5 of the car can be illuminated by multiple sets of direct lights 33, improving visibility and making it easier for the operator to observe the chassis of the car. The assembly also includes a second circular sleeve 34, which is fixedly connected to one side of the side plate 31. An angled spotlight 35 is rotatably connected inside the second circular sleeve 34. When the direct spotlight 33 is turned on, the angled spotlight 35 is also turned on, increasing the illumination area. A second gear 36 is fixedly connected to the bottom of the outer wall of the angled spotlight 35. Multiple sets of the second circular sleeve 34, angled spotlight 35, and second gear 36 are provided and are arranged in parallel on one side of the side plate 31. The direct spotlight 33 and the angled spotlight 35 are staggered. A horizontal plate 37 is fixedly connected to one side of the side plate 31. The side of the horizontal plate 37 away from the side plate 31 is fixedly... Multiple sets of baffles 38 are connected, and the baffles 38 are positioned between the direct spotlight 33 and the oblique spotlight 35. A second hydraulic rod 40 is fixedly connected to one side of the side plate 31. A connecting rod 41 is fixedly connected to the output end of the second hydraulic rod 40, and a second rack 39 is fixedly connected to one end of the connecting rod 41. When it is necessary to test a specific position of the chassis, the second hydraulic rod 40 can be activated as needed, pushing the second rack 39 to one side. The second rack 39 is slidably mounted on the top of the horizontal plate 37, and the second rack 39 meshes with one side of multiple sets of second gears 36. By setting the horizontal plate 37, the second... The rack 39 is lifted up, and multiple baffles 38 set on one side of the horizontal plate 37 can limit one side of the second rack 39 to prevent the second rack 39 from being disturbed when it moves. When the second rack 39 moves, it can drive multiple sets of second gears 36 meshing on one side to rotate. Since the multiple sets of second gears 36 are fixed below the multiple sets of angled lights 35, the angle of the angled lights 35 can be adjusted by moving the second rack 39 until the angle of a set of angled lights 35 illuminates the position to be observed. The brightness of a specific position can be increased as needed to facilitate the operator to detect gaps.

[0024] like Figure 1 and Figure 2 As shown, a square groove is provided at the center of the top of the pallet 1. By providing a square groove at the top of the pallet 1, it is convenient to install the anti-slip plate 42 in the square groove. The anti-slip plate 42 is fixed to the inner wall of the square groove. Multiple sets of protruding strips are fixed to the top of the anti-slip plate 42. When the front wheels of the vehicle drive to the center of the top of the pallet 1, the front wheels of the car will contact the anti-slip plate 42. The multiple sets of protruding strips provided at the top of the anti-slip plate 42 can provide an anti-slip effect for the front wheels of the car and prevent the wheels from slipping due to the smooth top of the pallet 1.

[0025] A vehicle chassis clearance detection system includes the aforementioned vehicle chassis clearance detection device.

[0026] Working principle: To solve the problem of wheel instability when detecting the chassis clearance of a car, when the chassis of a car needs to be inspected, the first hydraulic rod 6 can be activated according to the height of the car. The first hydraulic pressure pushes the first round rod 8 to one side. The first round rod 8 will slide on the inner wall of the first sliding frame 10, and the first sliding frame 10 will also limit the movement of the first round rod 8. When the first round rod 8 moves, it will drive the bottom of the second support rod 9 to one side, and the top of the second support rod 9 will also move downward. When the second support rod 9 moves downward, it will drive the support plate 1 to move downward, and at the same time, it will squeeze the first support rod 7 downward. When the first support rod 7 moves downward, it can be limited by the second round rod 12 sliding in the second sliding frame 11, causing the support plate 1 to move downward in a straight line until the support plate 1 is adjusted to the height of the car, so that the car can be driven onto the support plate 1. When a car needs to drive onto pallet 1, a connecting plate 27 is installed on one side of pallet 1. The inclined top of the connecting plate 27 allows the car wheels to drive onto the connecting plate 27 and move towards the top of pallet 1. An arc-shaped guide plate 28 guides both rows of car wheels, ensuring precise placement onto pallet 1. Since a circular roller 29 is installed on one side of the guide plate 28, it helps the wheels pass over the roller 29, preventing scratches. Furthermore, multiple sets of circular rollers 29 are positioned... Multiple sets of airbags 30 are provided to protect the wheels in advance and prevent hard abrasions when the wheels come into contact with the rollers 29. Two sets of side plates 31 are set on both sides of the pallet 1 to limit the sides of the side plates 31, which effectively prevents the wheels from tilting when they drive to the middle of the pallet 1. When the front wheels of the vehicle drive to the center of the top of the pallet 1, the front wheels of the car will come into contact with the anti-slip plate 42. Multiple sets of convex strips set on the top of the anti-slip plate 42 can provide anti-slip effect for the front wheels of the car and prevent the wheels from slipping on the smooth top of the pallet 1. When the four sets of tires of the car drive onto the pallet 1, the tires will pass through the gap between the two sets of push blocks 20 and contact the inclined plate 25. After driving onto the inclined plate 25, the tires will drive to the top of the detection plate 4. By setting a groove at the top of the detection plate 4, it is easier to position the wheel within the detection plate 4 when the wheel drives into the groove. By setting anti-slip texture 26 on the detection plate 4, it is easier to increase the friction between the detection plate 4 and the wheel. When all four sets of tires are in the positions of the four sets of detection plates 4, the drive motor 13 can be started, causing the drive motor 13 to drive... When the first gear 15 rotates, it drives the first racks 16 on both sides to move towards the center. Two sets of limiting strips 17 limit the movement of the two sets of first racks 16. As the first racks 16 move, they drive the horizontal bar 18 and the two sets of vertical bars 19 to move together. The two sets of vertical bars 19, in turn, drive the two sets of push blocks 20 to move. When the push blocks 20 move towards one side of the inclined plate 25, the first roller 21 will first contact the bottom of the inclined plate 25. Since the first roller 21 is located at the bottom of the inclined plate 25 and partially... Embedded within the chute, the inclined plate 25 can be lifted by the contact between the first roller 21 and the inclined plate 25. Once lifted, the inclined plate 25 will contact multiple sets of second rollers 22, and with the movement of the push block 20, it will slide off the multiple sets of second rollers 22, thus facilitating the flipping of the inclined plate 25. Since the inclined plate 25 is rotatably mounted on the vertical plate 24 via a pivot, it will flip upwards when lifted by the push block 20 until the top of the inclined plate 25 is flipped to the side of the car wheel. As both sets of first racks 16 move simultaneously towards the center... The movement causes another set of horizontal bars 18, two sets of vertical bars 19, and push blocks 20 to move towards the center. The four sets of push blocks 20 can push the two sets of inclined plates 25 upward, causing the two sets of inclined plates 25 to fix the two sides of the tire and prevent the tire from slipping off the detection plate 4 during the test. Then, the hydraulic system 3 is activated, which can drive the detection plate 4 to move laterally or longitudinally as needed. When the detection plate 4 moves, it can cause the tires and chassis of the car to shake. The operator can identify the gaps in the car chassis by listening and observing. When it is necessary to inspect the chassis of a car, the direct spotlights 33 can be turned on. Since multiple sets of direct spotlights 33 are arranged in parallel, they can illuminate the chassis 5 of the car, improving visibility and making it easier for operators to observe the chassis. When the direct spotlights 33 are turned on, the angled spotlights 35 can also be turned on to increase the illuminated area. When it is necessary to inspect a specific location on the chassis, the second hydraulic rod 40 can be activated as needed. The second hydraulic rod 40 pushes the second rack 39 to one side, and the second rack 39 can be lifted by the crossbar 37. The multiple baffles 38 provided on one side of the horizontal plate 37 can limit one side of the second rack 39 to prevent the second rack 39 from being disturbed when it moves. When the second rack 39 moves, it can drive the multiple sets of second gears 36 meshing on one side to rotate. Since the multiple sets of second gears 36 are fixed below the multiple sets of angled lights 35, the angle of the angled lights 35 can be adjusted by moving the second rack 39 until the angle of a set of angled lights 35 illuminates the position that needs to be observed. The brightness of a specific position can be increased as needed, making it easier for the operator to observe the gaps on the car chassis.
