Description

Technical Field

[0001] This utility model relates to the technical field of road quality testing equipment, specifically a vehicle-mounted, mobile, rapid road testing device. Background Technology

[0002] With increasing traffic volume and aging roads, the demand for efficient and accurate road condition monitoring is constantly growing. Traditionally, road surface inspection methods rely heavily on manual visual inspection or fixed-point measurement, which is inefficient, has limited coverage, and poses safety hazards. To address these issues, researchers have begun developing vision-based automated inspection systems capable of rapidly identifying and assessing road surface defects such as unevenness, cracks, and potholes.

[0003] Traditional vehicle-mounted PTZ camera mounting brackets have certain limitations. Many commercially available brackets are designed for specific vehicle types, meaning they may only fit certain brands or models of cars. For example, some brackets specifically designed for police cars, military vehicles, escort vehicles, and urban management patrol cars are customized in size and shape to meet the specific needs of these vehicles, making them difficult to apply directly to ordinary private cars or other types of commercial vehicles. Furthermore, the height of typical vehicle-mounted PTZ camera tripods is fixed, requiring the replacement of the appropriate tripod for height adjustment, which is cumbersome. Utility Model Content

[0004] The present invention aims to provide a vehicle-mounted mobile road surface rapid detection device. The height and width of the detection device are adjustable, which facilitates good adaptation to vehicles of different sizes and specifications.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A vehicle-mounted mobile road surface rapid detection device includes a stand mounted on the roof of a vehicle. Multiple threaded rods are fixedly mounted on the top of the stand. Mounting plates are slidably connected to the threaded rods. Nuts are threadedly connected to the upper and lower ends of the threaded rods, and the nuts are fixed on the upper and lower sides of the mounting plates to fix the mounting plates at different positions on the threaded rods.

[0007] The top of the mounting plate is slidably connected to an anti-vibration pad, and the top of the anti-vibration pad is fixedly installed with the main body of the detection equipment for road surface detection.

[0008] The mounting plate has mounting bases mirror-mounted on both sides of its bottom. One mounting base on one side has a first pull tab fixedly mounted on it, and the other mounting base on the other side has a second pull tab fixedly mounted on it. The installation distance between the second pull tab and the mounting base can be adjusted along the length of the mounting plate.

[0009] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:

[0010] When needed, first use the first pull tab to fix it to one side of the vehicle roof, then hook the second pull tab to the other side of the vehicle roof. By turning the hexagonal bolt, the second pull tab can be moved and tightened, making the tripod and mounting plate stably fixed on the vehicle roof. When there is an obstruction in front of the PTZ camera or the height needs to be adjusted to change the viewing angle, the position of the nut is turned to move the mounting plate on the threaded rod, and then the nut is used to fix it again. This allows for adjustment of the height of the mounting plate, making it easy to quickly find the appropriate detection height. The cooperation between the slider and the slide groove allows the anti-vibration pad and the PTZ camera to move flexibly within a certain range. At the same time, the friction damping set between the slider and the slide groove can use friction to stabilize the anti-vibration pad relative to the mounting plate after it is moved to the appropriate position. Even if the vehicle is bumpy, the anti-vibration pad will not slide at will, ensuring the stability of the PTZ camera detection process. When it is necessary to fine-tune the camera position, the friction damping can be overcome to make fine adjustments to meet the requirements of high-precision detection.

[0011] In a preferred embodiment, the present invention can be further configured such that: the number of the tripods is two, and the two tripods are arranged symmetrically in a mirror image along the center line of the mounting plate.

[0012] In a preferred embodiment, the present invention can be further configured such that rubber pads are fixedly connected to the bottom of both legs.

[0013] In a preferred embodiment, the present invention can be further configured such that: the number of threaded rods is four, with each pair of threaded rods forming a group for use, and the top end of the threaded rods is fixed to the bracket.

[0014] In a preferred embodiment, the present invention can be further configured such that: both ends of the mounting plate are provided with through holes adapted to the threaded rod, and the threaded rod is arranged through the through holes.

[0015] In a preferred embodiment, the present invention can be further configured such that: a groove is provided on the top of the mounting plate, and a slider adapted to the groove is fixedly connected to the bottom of the shock-absorbing pad.

[0016] In a preferred embodiment, the present invention can be further configured such that: the first pull tab is fixed to the fixed base by a hexagonal head short bolt, and the second pull tab is fixed to the fixed base by a hexagonal head long bolt; the installation distance between the second pull tab and the fixed base can be adjusted by rotating the hexagonal head long bolt.

[0017] In a preferred embodiment, the present invention can be further configured such that the main body of the detection device is a pan-tilt camera.

[0018] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0019] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0020] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0021] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0022] A movable connection refers to a connection in which parts or components are fixed but have relative motion.

[0023] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0024] 1. The first and second pull tabs in this utility model can be adjusted to fix the position, adapt to vehicles of different widths, and quickly adjust the height and horizontal position when there is obstruction in front of the pan-tilt camera or when the height needs to be adjusted to change the viewing angle.

[0025] 2. The detection device of this utility model adopts a lightweight design and has good buffering and shock absorption effects. After being installed on the roof of the vehicle, it can quickly detect the road surface while the vehicle is in motion. It is simple to install and convenient to use. Attached Figure Description

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0032] Based on the concept of this application, combined with Figures 1 to 3 This document describes an embodiment of a vehicle-mounted, mobile, rapid road surface detection device that is conveniently installed on the roof of a vehicle 10 for road surface inspection. Specifically, the vehicle-mounted, mobile, rapid road surface detection device is constructed as a split structure, comprising four components: a stand 22, a threaded rod, a mounting plate 26, and the main body 27 of the detection device. The device's fixed position can be adjusted using a first pull tab 32 and a second pull tab 21, accommodating vehicles of different widths. Furthermore, it allows for rapid adjustment of both height and horizontal position when there are obstructions in front of the pan-tilt camera or when the viewing angle needs to be changed by adjusting the height.

[0033] Combination Figures 1-3 As shown, the present invention provides a vehicle-mounted mobile road surface rapid detection device, including a stand 22 installed on the top of a car 10. Multiple threaded rods are fixedly installed on the top of the stand 22. Mounting plates 26 are slidably connected to the threaded rods. Nuts 25 are threadedly connected to the upper and lower parts of the threaded rods respectively. The nuts 25 are fixed on the upper and lower sides of the mounting plate 26 to fix the mounting plate 26 at different positions of the threaded rods.

[0034] The top of the mounting plate 26 is slidably connected to a shock-absorbing pad 28, and the top of the shock-absorbing pad 28 is fixedly installed with the main body of the detection equipment 27 for road surface detection.

[0035] Mounting plates 26 have mounting bases 30 mirror-mounted on both sides of their bottom. One mounting base 30 has a first pull tab 32 fixedly mounted on it, and the other mounting base 30 has a second pull tab 21 fixedly mounted on it. The installation distance between the second pull tab 21 and the mounting base 30 can be adjusted along the length of the mounting plate 26.

[0036] In this embodiment, two tripods 22 are used, arranged symmetrically in a mirror image along the center line of the mounting plate 26. Each tripod 22 has a rubber pad 23 fixedly connected to its bottom. In actual use, the bottom of the tripod 22 rests against the roof. The rubber pad 23 is soft and has a high surface roughness, significantly increasing the friction between the tripod 22 and the roof. This ensures the stability of the main body 27 of the testing equipment during vehicle operation, even in complex road conditions such as bumps, sudden braking, or sharp turns, preventing slippage and ensuring the continuity and accuracy of the testing work. Furthermore, the rubber pad 23 provides excellent cushioning for the roof surface, effectively preventing scratches, wear, and other damage to the roof during installation or use, maintaining the integrity and aesthetics of the roof.

[0037] In this embodiment, four threaded rods are used in pairs, with the top of each threaded rod fixed to the bracket 22. Both ends of the mounting plate 26 have through holes adapted to the threaded rods, through which the threaded rods pass. In actual use, the position of the nut 25 is adjusted to move the mounting plate 26 on the threaded rods, and then the nut 25 is used to re-fix it, thus adjusting the height of the mounting plate 26. This flexibility in height adjustment is crucial when facing different vehicle models, different testing requirements, or complex road conditions, allowing for a quick and suitable testing height. This enables the main body of the testing equipment 27 to better adapt to various scenarios without the need for additional complex disassembly or replacement of parts, making operation simple and quick, and greatly improving the practicality and versatility of the device.

[0038] Regarding the technical solution of this embodiment, the top of the mounting plate 26 is provided with a sliding groove, and the bottom of the anti-vibration pad 28 is fixedly connected with a slider that matches the sliding groove. There is a certain frictional damping between the slider and the sliding groove. The cooperation between the slider and the sliding groove allows the anti-vibration pad 28 and the PTZ camera to move flexibly within a certain range. At the same time, the frictional damping provided between the slider and the sliding groove can use friction to keep the anti-vibration pad 28 stable and fixed relative to the mounting plate 26 after it has moved to a suitable position. Even if the vehicle is bumpy, the anti-vibration pad 28 will not slide at will, ensuring the stability of the PTZ camera detection process. When it is necessary to fine-tune the camera position, the frictional damping can be overcome to make fine adjustments, meeting the requirements of high-precision detection.

[0039] Regarding the technical solution of this embodiment, the first pull tab 32 is fixed to the fixed base 30 by a hexagonal head short bolt 31, and the second pull tab 21 is fixed to the fixed base 30 by a hexagonal head long bolt 29. By rotating the hexagonal head long bolt 29, the installation distance between the second pull tab 21 and the fixed base 30 can be adjusted, so that the main body 27 of the detection equipment can better fit the roof contour, achieve quick and stable installation, broaden the application range of the device, and facilitate good adaptation to vehicle models with different roof shapes and sizes.

[0040] In this embodiment, the main body 27 of the detection device is configured as a pan-tilt camera.

[0041] Specifically, when needed, the device is first fixed to one side of the roof using the first pull tab 32, and then hooked to the other side of the roof using the second pull tab 21. The second pull tab 21 is then moved by rotating the hexagonal bolt to tighten it, thus securing the tripod 22 and mounting plate 26 stably on the roof. When there is an obstruction in front of the PTZ camera or when the height needs to be adjusted to change the viewing angle, the position of the nut 25 is turned to move the mounting plate 26 on the threaded rod. The nut 25 is then re-secured, allowing adjustment of the mounting plate 26's height for quick and easy detection. The cooperation between the slider and the groove allows the anti-vibration pad 28 and the PTZ camera to move flexibly within a certain range. The friction damping between the slider and the groove ensures that the anti-vibration pad 28 is stably fixed relative to the mounting plate 26 after moving to the appropriate position. Even with vehicle bumps, the anti-vibration pad 28 will not slide freely, ensuring stable PTZ camera detection. Furthermore, when fine-tuning the camera position is required, the friction damping can be overcome for precise adjustments, meeting high-precision detection requirements.

[0042] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the vehicle-mounted mobile road surface rapid detection device provided by this utility model.

[0043] A vehicle-mounted mobile road surface rapid detection device includes a stand 22 mounted on the top of a vehicle 10. Multiple threaded rods are fixedly mounted on the top of the stand 22. Mounting plates 26 are slidably connected to the threaded rods. Nuts 25 are threadedly connected to the upper and lower sides of the threaded rods respectively. The nuts 25 are fixed on the upper and lower sides of the mounting plate 26 to fix the mounting plate 26 at different positions of the threaded rods.

[0044] The top of the mounting plate 26 is slidably connected to a shock-absorbing pad 28, and the top of the shock-absorbing pad 28 is fixedly installed with the main body of the detection equipment 27 for road surface detection.

[0045] Mounting plates 26 have mounting bases 30 mirror-mounted on both sides of their bottom. One mounting base 30 has a first pull tab 32 fixedly mounted on it, and the other mounting base 30 has a second pull tab 21 fixedly mounted on it. The installation distance between the second pull tab 21 and the mounting base 30 can be adjusted along the length of the mounting plate 26.

[0046] The working principle and usage process of this utility model are as follows: When needed, firstly, the device to be tested is fixed to one side of the vehicle roof using the first pull tab 32. Then, the second pull tab 21 is hooked onto the other side of the vehicle roof. By rotating the hexagonal bolt, the second pull tab 21 is moved and tightened, thus stably fixing the tripod 22 and the mounting plate 26 to the vehicle roof. When there is an obstruction in front of the pan-tilt camera or when the height needs to be adjusted to change the viewing angle, the position of the nut 25 is turned, causing the mounting plate 26 to move on the threaded rod. Then, the nut 25 is used to fix it again, thus adjusting the usage height of the mounting plate 26. The design facilitates quick and easy finding of the appropriate detection height. The cooperation between the slider and the slide groove allows the anti-vibration pad 28 and the PTZ camera to move flexibly within a certain range. At the same time, the friction damping set between the slider and the slide groove can use friction to stably fix the anti-vibration pad 28 relative to the mounting plate 26 after it has been moved to the appropriate position. Even if the vehicle is bumpy, the anti-vibration pad 28 will not slide at will, ensuring the stability of the PTZ camera detection process. When it is necessary to fine-tune the camera position, the friction damping can be overcome to make fine adjustments, meeting the requirements of high-precision detection. After use, disassembly can be completed by removing the first pull tab 32 and the second pull tab 21.
