Description

Technical Field

[0001] This utility model relates to the field of vehicle undercarriage inspection technology, and in particular to a vehicle undercarriage inspection robot. Background Technology

[0002] In modern transportation systems, the safe operation of vehicles is crucial to public safety and social stability. The underside of a vehicle, as an area with densely packed vehicle parts and complex structures, is a high-risk area for concealing contraband and experiencing mechanical failures. Using robots to inspect vehicle chassis can improve the efficiency of vehicle safety inspections and also promote the development of the automotive aftermarket.

[0003] After the vehicle is parked, place the robot at the front of the vehicle. Using the controller in the operator's hand, control the robot to move under the vehicle and use its built-in camera to film the undercarriage. The video data is then transmitted to the staff, who use the footage to determine if there are any safety hazards in the undercarriage.

[0004] Existing undercarriage inspection robots leave their cameras exposed to the air when not in use, resulting in dust accumulation on the camera lens. When the cameras are used again, they need to be wiped clean, but the fine dust particles can scratch the lens, affecting usability. This also makes it difficult to quickly replace the battery pack. Therefore, a new undercarriage inspection robot is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a vehicle undercarriage inspection robot.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a vehicle undercarriage inspection robot, including a walking frame, with protective mechanisms provided on one side and top of the walking frame, and locking mechanisms provided on both sides of the walking frame.

[0007] As a preferred embodiment of the undercarriage inspection robot of this utility model, the protective mechanism includes a camera mounted on the top of the walking frame, a cover plate on the top of the camera, side blocks fixedly mounted on both sides of the cover plate, L-shaped clamping plates symmetrically arranged inside the side blocks, a push rod fixedly connected to one side of the L-shaped clamping plate, a limit plate fixedly connected to one side of the push rod, a push rod mounted on one side of the limit plate, and T-shaped slots adapted to the L-shaped clamping plates on both sides of the camera.

[0008] As a preferred embodiment of the undercarriage inspection robot of this utility model, the locking mechanism includes battery packs disposed on both sides inside the walking frame. The walking frame has a housing symmetrically arranged on its inner surface. A limit rod is movably inserted into the housing. A locking rod is fixedly connected to one side of the limit rod. The battery pack has slots on both sides that are adapted to the locking rod.

[0009] As a preferred embodiment of the undercarriage inspection robot of this utility model, the side block has sliding grooves on both sides of the center of the interior, which are adapted to the L-shaped card plate and the limiting plate, and the L-shaped card plate and the limiting plate are slidably connected inside the sliding grooves.

[0010] In a preferred embodiment of the undercarriage inspection robot of this utility model, the side block has symmetrically provided circular holes on one side that are adapted to the push rod, the push rod is slidably connected inside the circular holes, and the circular holes of the side block are connected to the sliding groove.

[0011] In a preferred embodiment of the undercarriage inspection robot of this utility model, the limiting plate is provided with first springs on both sides, the first springs are located on both sides of the L-shaped clamping plate, the outer end face of the push rod is fixedly connected to a push plate, and the cover plate is adapted to the camera.

[0012] In a preferred embodiment of the undercarriage inspection robot described in this utility model, the battery pack is movably inserted into the walking frame, the limiting rod is rotatably connected to the inside of the battery pack, and one end of the battery pack extends into the inside of the battery pack and is fixedly connected to a handle.

[0013] In a preferred embodiment of the undercarriage inspection robot of this utility model, the limiting rod is fixedly installed with a limiting ring on the outer surface of the inner cavity of the housing, and a second spring is provided on one side of the limiting ring, the second spring being located outside the limiting rod.

[0014] This utility model provides a robot for inspecting under-vehicle areas. It has the following beneficial effects: 1. Through the protective mechanism, when the walking frame is not in use, it can protect the cameras on the top and one side of the walking frame, preventing dust from falling on the camera lens. Pushing two push plates simultaneously towards the center of the cover plate, the two push plates push the corresponding push rods inward, and the push rods push the corresponding limit plates, thereby pushing the two L-shaped locking plates towards each other. At this time, the cover plate is locked on the top of the camera. At this time, the L-shaped locking plates are locked into the T-shaped locking slots on the side of the camera. Releasing the pushing force on the two push plates, under the action of the first spring, push the corresponding two L-shaped locking plates in opposite directions, so that the L-shaped locking plates are locked into the T-shaped locking slots of the camera, fixing the cover plate on the top of the walking frame, thus protecting the camera and preventing dust from falling on the camera lens when the camera is not in use.

[0015] 2. The snap-fit ​​mechanism allows for quick assembly and disassembly of the battery pack. After prolonged use, the battery's range decreases, requiring replacement. Manually rotate the handle to a vertical position. This rotates the limit rod, changing the snap-fit ​​lever from a horizontal to a vertical position, removing it from the battery pack's slot. Once both snap-fit ​​levers on both sides of the battery pack are removed, pull the battery pack out of the frame and replace it with a new one. Rotate the snap-fit ​​lever in the opposite direction to a horizontal position, stabilizing the battery pack in the frame. This facilitates easy battery pack replacement. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a vehicle undercarriage inspection robot, including a walking frame 1. A protective mechanism 2 is provided on one side and the top of the walking frame 1, and a locking mechanism 3 is provided on both sides of the walking frame 1.

[0026] The protective mechanism 2 includes a camera 201 mounted on the top of the walking frame 1. A cover plate 202 is mounted on the top of the camera 201. Side blocks 203 are fixedly installed on both sides of the cover plate 202. L-shaped clamping plates 206 are symmetrically arranged inside the side blocks 203. A push rod 204 is fixedly connected to one side of the L-shaped clamping plate 206. A limit plate 208 is fixedly connected to one side of the push rod 204. The push rod 204 is mounted on one side of the limit plate 208. T-shaped slots adapted to the L-shaped clamping plates 206 are opened on both sides of the camera 201.

[0027] Specifically, both push rods 204 on both sides are pushed toward the center of the camera 201, and the cover plate 202 is locked onto the top of the camera 201. When the two L-shaped plates 206 on both sides move in opposite directions, each pair of L-shaped plates 206 is locked into the corresponding T-shaped slot. Under the action of the cover plate 202, the camera 201 is protected to a certain extent.

[0028] Specifically, both sides of the center of the side block 203 are provided with sliding grooves that are adapted to the L-shaped card plate 206 and the limiting plate 208. The L-shaped card plate 206 and the limiting plate 208 are slidably connected inside the sliding grooves. Under the action of the limiting plate 208, when the push rod 204 is pushed inward, the limiting plate 208 pushes the L-shaped card plate 206 inward, so that the L-shaped card plate 206 moves stably in the sliding groove of the side block 203.

[0029] Specifically, the side block 203 has symmetrical circular holes on one side that are adapted to the push rod 204. The push rod 204 is slidably connected inside the circular holes. The circular holes of the side block 203 are connected to the slide groove. When the push rod 204 is pushed inward, the circular holes enable the push rod 204 to move stably in the horizontal direction.

[0030] Specifically, the limiting plate 208 is provided with first springs 207 on both sides. The first springs 207 are located on both sides of the L-shaped card plate 206. The outer end face of the push rod 204 is fixedly connected to the push plate 205. The cover plate 202 is adapted to the camera 201. Under the action of the two first springs 207, when the push rod 204 is not pushed by external force, the two first springs 207 can push the limiting plate 208 towards the push plate 205, thereby pulling the corresponding L-shaped card plate 206, so that the L-shaped card plate 206 is stably locked in the T-shaped card slot of the camera 201.

[0031] Furthermore, the two push plates 205 are simultaneously pushed toward the center of the cover plate 202. The two push plates 205 push the corresponding two push rods 204 inward, and the push rods 204 push the corresponding limiting plate 208, thereby pushing the two L-shaped clamping plates 206 toward each other. At this time, the cover plate 202 is clamped on the top of the camera 201. At this time, the L-shaped clamping plates 206 are clamped into the T-shaped clamping slot on one side of the camera 201. The pushing force on the two push plates 205 is removed. Under the action of the first spring 207, the corresponding two L-shaped clamping plates 206 are pushed in opposite directions, so that the L-shaped clamping plates 206 are clamped into the T-shaped clamping slot of the camera 201, and the cover plate 202 is fixed on the top of the walking frame 1. Example

[0032] Reference Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The locking mechanism 3 includes a battery pack 301 disposed on both sides inside the walking frame 1. A housing 302 is symmetrically disposed on the inner surface of the walking frame 1. A limiting rod 303 is movably inserted into the housing 302. A locking rod 304 is fixedly connected to one side of the limiting rod 303. The battery pack 301 has slots on both sides that are adapted to the locking rod 304.

[0033] Specifically, the clamping rod 304 is rotated to a vertical position via the limiting rod 303. After the battery pack 301 is fully inserted into the frame 1, the clamping rod 304 is rotated toward the slot of the battery pack 301 via the limiting rod 303. The clamping rod 304 is rotated to a horizontal position. The battery pack 301 is then fixed inside the frame 1 by the clamping rods 304 on both sides of the battery pack 301.

[0034] Specifically, the battery pack 301 is movably inserted into the walking frame 1, and the limiting rod 303 is rotatably connected inside the battery pack 301. One end of the battery pack 301 extends into the interior and is fixedly connected to a handle 305. A limiting ring 307 is fixedly installed on the outer surface of the inner cavity of the housing 302. A second spring 306 is provided on one side of the limiting ring 307. The second spring 306 is located outside the limiting rod 303. Under the action of the second spring 306, a pushing force is applied to the limiting ring 307 in the direction of the handle 305, so that the limiting rod 303 obtains an outward pushing force, thereby keeping the locking rod 304 in a vertical or horizontal state.

[0035] Furthermore, manually rotate handle 305 to a vertical position. At this time, handle 305 drives limit rod 303 to rotate, changing clamp rod 304 from a horizontal position to a vertical position. Remove clamp rod 304 from the slot of battery pack 301. After clamp rods 304 on both sides of battery pack 301 are removed from the slot, pull battery pack 301 out of walking frame 1, replace it with a new battery pack 301, and rotate clamp rod 304 in the opposite direction to a horizontal position to stabilize battery pack 301 in walking frame 1.

[0036] Working principle: The walking frame 1 is equipped with an imaging module, an image separation module, an image processing module, and a wireless connection module. The walking frame 1 has wheels around its perimeter, driven by a motor, similar to existing publicly available models. When an inspection of the undercarriage is required, the walking frame 1 moves using these wheels. Cameras 201 on the top and side of the walking frame 1 capture images of the undercarriage. The images are then transmitted wirelessly to the operator's control module. The transmitted images are used to determine the specific condition of the undercarriage. When the walking frame 1 is not in use, the cover plate 202 is removed, and the two push plates 205 on the outer side of the cover plate 202 are simultaneously pushed towards the center of the cover plate 202. The two push plates 205 push the corresponding push rods 204 inwards, which in turn push the corresponding limit plates 208, thus pushing the two L-shaped clamping plates 206 towards each other. At this point, the cover plate 202 is secured to the top of the camera 201, and the L-shaped clamping plates 206 are engaged in the T-shaped slots on one side of the camera 201. The two push plates are then removed. The thrust on 205, under the action of the first spring 207, pushes the two corresponding L-shaped locking plates 206 in opposite directions, causing the L-shaped locking plates 206 to snap into the T-shaped slots of the camera 201. After the L-shaped locking plates 206 on both sides of the camera 201 are fixed, the cover plate 202 can be placed on top of the walking frame 1. The other cover plate 202 is then placed on the other camera 201 on one side of the walking frame 1 using the same method. During long-term use of the walking frame 1, the battery pack 301 needs to be... When replacing the battery pack, manually rotate handle 305 to a vertical position. At this time, handle 305 will rotate limit rod 303, changing the locking rod 304 from a horizontal to a vertical position. Move the locking rod 304 out of the slot of battery pack 301. After both locking rods 304 on both sides of battery pack 301 have been moved out of the slot, pull battery pack 301 out of the walking frame 1, replace it with a new battery pack 301, and rotate the locking rod 304 in the opposite direction to a horizontal position. Stabilize battery pack 301 in walking frame 1 to complete the replacement.
