Abstract
Description
Technical Field
[0001] This application belongs to the field of camera technology, and more specifically, relates to an information collection device for automatic detection of road safety hazards. Background Technology
[0002] Currently, road safety hazard investigation mainly relies on manual inspections and some automated equipment. Manual inspections have many drawbacks. On the one hand, they are extremely inefficient, requiring a large amount of manpower and time, especially for long-distance highways or complex urban road networks, making comprehensive and rapid inspections difficult. On the other hand, they are costly, not only incurring labor expenses but also potentially causing indirect losses due to traffic disruptions. Furthermore, manual inspections also pose certain safety risks, as inspectors are vulnerable to threats from passing vehicles while working on the road.
[0003] Therefore, automated inspection equipment is gaining increasing popularity. Current technologies typically include unmanned driving platforms, information collection devices, analysis devices, and report generation devices. Among these, cameras are the most commonly used and effective information collection devices for automated road safety hazard inspection. However, during prolonged operation, dust often accumulates on the camera lens caps, leading to reduced image accuracy or even malfunction, thus decreasing the efficiency of safety hazard inspection. Utility Model Content
[0004] The purpose of this application is to provide an information collection device for automatic road safety hazard investigation, so as to prevent the camera from being covered in dust and improve the efficiency of safety hazard investigation.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: An information collection device for automatic road safety hazard investigation is provided, comprising multiple cameras, multiple mounting plates, multiple first rotating shafts, multiple second rotating shafts, multiple high-transparency films, and multiple timing drive mechanisms. The multiple cameras are mounted on the top of an unmanned driving platform and electrically connected to the platform, providing road information to the platform. The mounting plates correspond one-to-one with each camera, are detachably mounted on the corresponding camera, and extend forward of the camera. The multiple first rotating shafts correspond one-to-one with each camera and are rotatably mounted on the corresponding mounting plates. The multiple second rotating shafts correspond one-to-one with the first rotating shafts. The first and second rotating shafts are respectively located on both sides of the corresponding camera, and the first and second rotating shafts are parallel to each other. Multiple high-transparency films correspond one-to-one with the first rotating shaft, with one end connected to the corresponding first rotating shaft and wound around it. The other end of the high-transparency film is connected to the corresponding second rotating shaft, and the high-transparency film covers the lens cap of the corresponding camera. A timing drive mechanism is located on the corresponding mounting plate and is poweredly connected to the second rotating shaft. The timing drive mechanism is used to drive the second rotating shaft to rotate a preset number of times at preset intervals, so as to replace the dirty high-transparency film covering the lens cap with a clean high-transparency film.
[0006] In one possible implementation, the mounting plate is positioned above the corresponding camera, and the corresponding first and second rotating shafts are both rotatably positioned at the bottom of the mounting plate.
[0007] In one possible implementation, a dustproof sleeve is fitted over both the first and second rotating shafts. The top of the dustproof sleeve is connected to the mounting plate. The dustproof sleeve has a through hole, and a high-permeability membrane wrapped around the first and second rotating shafts is placed inside the dustproof sleeve. The high-permeability membrane extends out of the dustproof sleeve through the through hole.
[0008] In one possible implementation, both the first and second rotating shafts are provided with T-shaped grooves, the T-shaped grooves extending along the axial direction of the first rotating shaft, and the two ends of the high-transparency membrane are provided with mounting blocks conforming to the T-shaped grooves, the mounting blocks being inserted into the T-shaped grooves.
[0009] In one possible implementation, the bottom end of the T-groove is flush with the bottom ends of the first and second rotating shafts, the bottom end of the dustproof cylinder extends below the high-permeability membrane, and the bottom end of the dustproof cylinder is screwed with a sealing bottom. A limiting platform is provided inside the sealing bottom, and the limiting platform abuts against the bottom end of the high-permeability membrane wound on the first or second rotating shaft.
[0010] In one possible implementation, two soft scrapers are provided near the through hole of the dustproof cylinder. The two soft scrapers are respectively pressed against both sides of the high-permeability membrane, and the length of the soft scrapers is the same as the width of the high-permeability membrane, so that the dirt on the surface of the high-permeability membrane entering the dustproof cylinder is scraped off by the soft scrapers.
[0011] In one possible implementation, the top end of the second rotating shaft extends above the mounting plate, and a first gear is provided on the second rotating shaft. The timing drive mechanism includes a motor and a timing switch, which are mounted on the mounting plate. A second gear is provided at the power output end of the motor, and the second gear meshes with the first gear. The timing switch is connected in series between the motor and the power supply of the autonomous driving platform. When the timing switch closes at a first preset time interval, the motor drives the first gear to rotate, and the timing switch automatically opens after a second preset time interval. A first protective box is provided on the mounting plate, which encloses the first gear, the second gear, the motor, and the timing switch.
[0012] In one possible implementation, the timer switch includes a first timer switch and a second timer switch, which are closed alternately. When the first timer switch is closed, the motor drives the second gear to rotate forward; when the second timer switch is closed, the motor drives the second gear to rotate in reverse. The top end of the first rotating shaft extends above the mounting plate. The mounting plate is provided with a second protective box, which covers the top of the first rotating shaft. A torsion spring is provided between the first rotating shaft and the second protective box, and the torsion spring is configured to have a preload force to wrap the high-permeability film around the first rotating shaft.
[0013] In one possible implementation, two mounting strips are slidably provided on the mounting plate, and each mounting strip is provided with a mounting clamp near its top end, the mounting clamp being fixed to the corresponding camera; a limiting plate is provided at both ends of the mounting plate, the mounting strip is slidably disposed between the limiting plates, and a limiting rod is screwed onto the mounting strip, the limiting rod abutting against the limiting plate on the outside of the mounting strip.
[0014] In one possible implementation, the mounting hoop is semi-circular, and mounting ears are provided on both sides of the mounting hoop extending radially outward. The mounting ears are provided with threaded holes, and bolts are screwed onto the corresponding mounting ears of different mounting hoops to tighten the two mounting hoops onto the camera.
[0015] The beneficial effects of the information collection device for automatic road safety hazard investigation provided in this application are as follows: Compared with the prior art, this application avoids direct contact between the lens cover and external dust by covering the camera lens cover with a high-transparency film. At the same time, the timed drive mechanism can automatically drive the second rotating shaft to rotate at preset intervals, so that the clean high-transparency film replaces the dirty part, realizing the "automatic update" of the lens coverage area. No manual cleaning is required, ensuring that the camera always collects information through a clean high-transparency film, effectively avoiding the reduction or failure of shooting accuracy caused by lens dust, and significantly improving the efficiency of safety hazard investigation.

[0024] The information collection device for automatic road safety hazard investigation provided in this application is described below.
[0025] Please refer to the following: Figures 1 to 7An information collection device for automatic road safety hazard detection includes multiple cameras 1, multiple mounting plates 2, multiple first rotating shafts 3, multiple second rotating shafts 4, multiple high-transparency films 5, and multiple timing drive mechanisms 6. The multiple cameras 1 are mounted on the top of an autonomous driving platform and electrically connected to it, providing road information to the platform. Each mounting plate 2 corresponds to one camera 1 and is detachably mounted on its corresponding camera 1, extending forward of the camera 1. Each first rotating shaft 3 corresponds to one camera 1 and is rotatably mounted on its corresponding mounting plate 2. Each second rotating shaft 4 corresponds to one first rotating shaft 3 and is rotatably mounted on its corresponding camera 1. On the corresponding mounting plate 2, the first rotating shaft 3 and the second rotating shaft 4 are respectively located on both sides of the corresponding camera 1, and the corresponding first rotating shaft 3 and the second rotating shaft 4 are parallel to each other; multiple high-transparency films 5 correspond one-to-one with the first rotating shaft 3, and one end is connected to the corresponding first rotating shaft 3 and wound on the first rotating shaft 3, and the other end of the high-transparency film 5 is connected to the corresponding second rotating shaft 4, and the high-transparency film 5 covers the lens cover of the corresponding camera 1; the timing drive mechanism 6 is located on the corresponding mounting plate 2, and the timing drive mechanism is poweredly connected to the second rotating shaft 4. The timing drive mechanism 6 is used to drive the second rotating shaft 4 to rotate a preset number of times at preset intervals, so as to replace the dirty high-transparency film 5 with a clean high-transparency film 5 to cover the lens cover.
[0026] The beneficial effects of the information collection device for automatic road safety hazard investigation provided in this embodiment are as follows: Compared with the prior art, the information collection device for automatic road safety hazard investigation provided in this embodiment covers the lens cover of the camera 1 with a high-transparency film 5 to prevent the lens cover from directly contacting external dust, thereby reducing lens contamination from the source; at the same time, the timed drive mechanism 6 can automatically drive the second rotating shaft 4 to rotate at preset intervals, so that the clean high-transparency film 5 replaces the dirty part, realizing the "automatic update" of the lens coverage area without manual cleaning, ensuring that the camera 1 always collects information through the clean high-transparency film 5, effectively avoiding the reduction or failure of shooting accuracy caused by lens dust, and significantly improving the efficiency of safety hazard investigation.
[0027] It is worth noting that in this embodiment, the high-transparency film 5 is made of wear-resistant TPU polyurethane material to prevent scratches from forming on the high-transparency film 5 during friction with the lens cover, thus affecting the shooting effect of the camera 1. In addition, the high-transparency film 5 between the first and second rotating shafts 4 in this embodiment is taut to prevent wrinkles from affecting its light transmittance.
[0028] like Figure 1 As shown, the mounting plate 2 is positioned above the corresponding camera 1, and the corresponding first rotating shaft 3 and second rotating shaft 4 are both rotatably positioned at the bottom of the mounting plate 2.
[0029] Mounting plate 2 is positioned above camera 1, with the first and second pivots located at the bottom of mounting plate 2. This ensures that the pivots and the mounting structure of the high-transparency film 5 do not obstruct the camera 1's field of view, guaranteeing that camera 1 can fully capture road information ahead and avoiding blind spots caused by unreasonable structural layout. Mounting plate 2, being above camera 1, can also shield against falling dust, rain, or debris to some extent, reducing the rate of contamination of the high-transparency film 5.
[0030] like Figure 1 and Figure 2 As shown, a dustproof cylinder 201 is fitted on the outside of the first rotating shaft 3 and the second rotating shaft 4. The top of the dustproof cylinder 201 is connected to the mounting plate 2. The dustproof cylinder 201 has a through hole, and the high-permeability membrane 5 wrapped around the first rotating shaft 3 and the second rotating shaft 4 is covered inside the dustproof cylinder 201. The high-permeability membrane 5 extends out of the dustproof cylinder 201 through the through hole.
[0031] The dust cover 201 encloses the high-transparency film 5 (especially the unused clean part) wrapped around the first and second rotating shafts, which can effectively block the entry of external dust and moisture, prevent the spare high-transparency film 5 from being contaminated during storage, and ensure that the high-transparency film 5 covering the lens is always clean when it is replaced, thus solving the potential problem of "premature contamination of spare film".
[0032] The through-hole on the dust cover 201 limits the extension direction of the high-transparency film 5, so that the high-transparency film 5 can only move along the preset path, avoiding the film from shifting or getting tangled during rotation and replacement, ensuring that the high-transparency film 5 can accurately cover the lens cover after each replacement, and improving the stability of the structure operation.
[0033] Meanwhile, the dust cover 201 can reduce dust adhering to the surface of the shaft, reduce wear during shaft rotation, extend the service life of the shaft, and reduce the frequency of equipment maintenance.
[0034] Combination Figure 4 and Figure 5 As shown, both the first rotating shaft 3 and the second rotating shaft 4 are provided with T-shaped grooves 301. The T-shaped grooves 301 extend along the axial direction of the first rotating shaft 3. The two ends of the high-permeability membrane 5 are provided with mounting blocks 501 that conform to the T-shaped grooves 301. The mounting blocks 501 are inserted into the T-shaped grooves 301.
[0035] The T-groove and T-mount block 501 provide dual axial and radial limits for the high-transparency film 5, ensuring that the high-transparency film 5 will not detach from the rotating shaft due to tension or vibration when rotating with the shaft. This ensures that the film remains stably connected during replacement and prevents the lens cap from being contaminated due to the film falling off.
[0036] When the high-transparency membrane 5 wears out, a new high-transparency membrane 5 can be quickly replaced by plugging and unplugging the T-shaped mounting block 501 without disassembling the entire shaft, which simplifies the maintenance process and reduces replacement and time costs, making it especially suitable for high-frequency use scenarios on autonomous driving platforms.
[0037] In addition, the T-shaped connection structure makes the high-transmittance film 5 more regularly wound on the rotating shaft, avoiding uneven local tension caused by loose connection of the film body, ensuring that the film surface is flat when covering the lens and does not affect the light transmission effect.
[0038] In this embodiment, the bottom end of the T-shaped groove 301 is flush with the bottom ends of the first rotating shaft 3 and the second rotating shaft 4. The bottom end of the dustproof cylinder 201 extends below the high-permeability membrane 5. The bottom end of the dustproof cylinder 201 is screwed with a sealing bottom 202. A limiting platform 203 is provided inside the sealing bottom 202. The limiting platform 203 abuts against the bottom end of the high-permeability membrane 5 wound on the first rotating shaft 3 or the second rotating shaft 4.
[0039] The bottom of the T-slot is flush with the bottom of the rotating shaft, allowing the T-shaped mounting block 501 to be directly inserted into the T-slot from the bottom of the rotating shaft without needing to align the top opening. This simplifies the installation of the high-transparency membrane 5, making it easier to operate, especially in confined spaces.
[0040] The bottom seal 202 and the limiting platform 203 at the bottom of the dustproof cylinder 201 can support the high-transparency film 5 wound on the rotating shaft, preventing the film from sagging due to its own weight, thus preventing the winding from becoming loose or shifting. This ensures that the film remains neat during storage and rotation, and can accurately cover the lens cap when replacing it.
[0041] The bottom seal 202 seals the bottom of the dustproof cylinder 201, further preventing dust from entering the interior of the dustproof cylinder 201 from the bottom. Together with the top mounting plate 2, it forms a fully enclosed storage space, maximizing the protection of the cleanliness of the spare high-transparency membrane 5. like Figure 3 As shown, two soft scrapers 204 are provided near the through hole of the dustproof cylinder 201. The two soft scrapers 204 are pressed against the two sides of the high-permeability membrane 5 respectively, and the length of the soft scraper 204 is the same as the width of the high-permeability membrane 5, so that the dirt on the surface of the high-permeability membrane 5 entering the dustproof cylinder 201 is scraped off by the soft scraper 204.
[0042] When the high-transparency film 5 passes through the through-hole into and out of the dustproof cylinder 201, the soft scrapers 204 on both sides will scrape off the dust, stains and other contaminants attached to its surface. Even if the high-transparency film 5 gets a small amount of contaminants during the lens covering process, it can be removed by the scraper, achieving the dual guarantee of "replacement and cleaning", ensuring that the high-transparency film 5 covering the lens is in the best clean state.
[0043] Soft materials such as silicone and rubber scrapers can effectively remove stains without scratching the surface of the high-transparency membrane, avoiding a decrease in membrane light transmittance due to cleaning operations, thus balancing cleaning effectiveness and membrane protection.
[0044] like Figure 1 and Figure 7 As shown, the top end of the second rotating shaft 4 extends above the mounting plate 2. The second rotating shaft 4 is provided with a first gear 401. The timing drive mechanism 6 includes a motor 601 and a timing switch. The motor 601 and the timing switch are located on the mounting plate 2. The power output end of the motor 601 is provided with a second gear 602. The second gear 602 meshes with the first gear 401. The timing switch is connected in series between the motor 601 and the power supply of the unmanned driving platform. When the timing switch closes every first preset time, the motor 601 drives the first gear 401 to rotate. The timing switch automatically opens after closing for a second preset time. The mounting plate 2 is provided with a first protective box 205, which covers the first gear 401, the second gear 602, the motor 601, and the timing switch.
[0045] Motor 601 drives the second rotating shaft 4 through the meshing of the second gear 602 and the first gear 401, resulting in high power transmission efficiency and strong stability, avoiding the slippage problems common in belt drives and other similar methods. A timer switch precisely controls the operating time of motor 601, including the closing time of the second preset time and the interval of the first preset time, ensuring accurate rotation of the second rotating shaft 4. This allows for precise control of the replacement length of the high-transparency film 5 to match the lens cap size, preventing incomplete coverage or waste due to film replacement being too long or too short.
[0046] The first protective box 205 encloses the drive components such as gears, motor 601, and timer switch, which can block the corrosion of external factors such as rainwater, dust, and stones, prevent the components from rusting, short circuits, or mechanical damage, significantly extend the service life of the timer drive mechanism 6, reduce the probability of failure, and ensure the long-term reliable operation of the timer replacement function.
[0047] In addition, the first protective box 205 centrally protects the drive components. During later maintenance, the protective box can be opened directly without disassembling the entire mounting plate 2, simplifying the maintenance process and reducing operation and maintenance costs.
[0048] Specifically, the timer switch includes a first timer switch 603 and a second timer switch 604. The first timer switch 603 and the second timer switch 604 are closed alternately. When the first timer switch 603 is closed, the motor 601 drives the second gear 602 to rotate forward. When the second timer switch 604 is closed, the motor 601 drives the second gear 602 to rotate in reverse. The top end of the first rotating shaft 3 extends above the mounting plate 2. The mounting plate 2 is provided with a second protective box, which covers the top of the first rotating shaft 3. A torsion spring is provided between the first rotating shaft 3 and the second protective box. The torsion spring is configured to have a preload force to wrap the high-permeability film 5 around the first rotating shaft 3.
[0049] In the initial state, a portion of the high-transparency film 5 is wrapped around the first rotating shaft 3, and another portion of the high-transparency film 5 covers the lens cap. When the automatic road safety hazard investigation information collection device of this utility model is turned on, the first timer switch 603 starts timing. After the first preset time of the first timer switch 603, the first timer switch 603 closes for a second preset time and then opens. During the second preset time of the first timer switch 603, the second rotating shaft 4 rotates clockwise, releasing the clean high-transparency film 5 from the first rotating shaft 3 to cover the lens, and simultaneously winding the dirty high-transparency film 5 onto the second rotating shaft 4. Of course, due to the presence of the soft scraper 204, the winding process is also a cleaning process.
[0050] Subsequently, the second timer switch 604 starts timing. After a first preset time, the second timer switch 604 closes for a second preset time and then opens. During the second preset time of the second timer switch 604, the second rotating shaft 4 reverses, releasing the clean high-transparency film 5 from the second rotating shaft 4 to cover the lens, while simultaneously winding the dirty high-transparency film 5 back onto the first rotating shaft 3. This process is repeated, allowing the high-transparency film 5 to be reused repeatedly, reducing consumable consumption and lowering long-term operating costs.
[0051] In this embodiment, the motor 601, the first timer switch 603, the second timer switch 604, and the power supply provided by the autonomous driving platform can be implemented using a PLC via ladder logic programming. When the first timer switch 603 starts and completes its timing, its normally open contact closes, starting the second timer switch 604 and simultaneously deactivating the first timer switch 603. After the second timer switch completes its timing, its normally closed contact resets the first timer switch 603 and restarts it, forming a cycle to complete the alternating timing of the first timer switch 603 and the second timer switch 604. Of course, besides this method, other applicable methods can also be used to make the first timer switch 603 and the second timer switch 604 time alternately.
[0052] like Figure 1 and Figure 2 As shown, two mounting strips 206 are slidably provided on the mounting plate 2. Each mounting strip 206 is provided with a mounting clamp 207 near the top position. The mounting clamp 207 is fixed to the corresponding camera 1. A limiting plate is provided at both ends of the mounting plate 2. The mounting strip 206 is slidably provided between the limiting plates. A limiting rod 210 is screwed onto the mounting strip 206. The limiting rod 210 abuts against the limiting plate on the outside of the mounting strip 206.
[0053] The mounting strip 206 can slide along the limiting plate to adjust the spacing of the mounting clamps 207, so that the same set of devices can be adapted to cameras 1 of different sizes, eliminating the need to design a separate installation structure for each type of camera 1, thus reducing equipment design and manufacturing costs.
[0054] The limiting rod 210 is screwed onto the mounting strip 206 and abuts against the limiting plate, which can fix the mounting strip 206 in any position, ensuring that the mounting clamp 207 is tightly fitted with the camera 1, preventing the mounting plate 2 from loosening or the high-transparency film 5 from shifting due to vibration during vehicle operation, and ensuring the stability of information acquisition. In this embodiment, the first and second protective boxes replace the function of the limiting rod 210.
[0055] The sliding structure and the limit rod 210 design allow the mounting plate 2 to be disassembled without complicated tools. Simply loosen the limit rod 210 to adjust or remove it, which facilitates the later inspection and replacement of the camera 1, the high-transparency film 5, or the drive mechanism, and improves maintenance efficiency.
[0056] Finally, the mounting clamp 207 is semi-circular, and mounting ears 208 extend radially outward on both sides of the mounting clamp 207. The mounting ears 208 have threaded holes, and bolts 209 are screwed onto the corresponding mounting ears 208 of different mounting clamps 207 to tighten the two mounting clamps 207 onto the camera 1. In this embodiment, one end of the mounting ear 208 is fixedly connected to the mounting strip 206.
[0057] Two semi-circular mounting clamps 207 are fastened to the mounting ears 208 by bolts 209. The clamping force can be flexibly adjusted according to the diameter of the camera 1, which can not only firmly fix the camera 1 of different diameters, but also prevent the camera 1 from being damaged due to excessive tightness, thus balancing the fixing effect and equipment protection.
[0058] The mounting ear 208 is connected by bolt 209. Installation or removal can be completed simply by tightening or loosening the bolt 209. No professional tools are required, which reduces the difficulty of installation and makes it easy to quickly replace the camera 1 or adjust the installation position.
[0059] The ring-shaped mounting clamp 207 has a large contact area with the surface of the camera 1, which can evenly distribute the fixing stress, avoid excessive local stress that could cause deformation or damage to the camera 1 housing, and extend the service life of the camera 1.
[0060] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
