Description

Technical Field

[0001] This utility model belongs to the field of endoscope assembly technology, specifically an endoscope assembly for carbon buildup inside automobiles. Background Technology

[0002] In the field of automotive engine carbon deposit detection, endoscope components are the core equipment for non-destructive testing. Existing endoscope components used for automotive interior carbon deposit detection are mainly divided into two categories: rigid endoscope components and flexible endoscope components, each with different structures and applicable scenarios.

[0003] For example, an automotive inspection endoscope with publication number CN219799886U includes a control assembly. A flexible metal tube is mounted on the control assembly, and an mounting cylinder is mounted on the flexible metal tube. A cylinder is fixedly mounted inside the mounting cylinder, and a sliding plate is fixedly connected to the cylinder rod. This invention utilizes a structure including a gear ring, motor, gears, connecting rods, a sliding cylinder, a baffle, a spring, a support ring, and a scraper. The motor drives the gears to rotate, which in turn causes the support ring to drive the scraper to brush the inspection head. Furthermore, the scraper, under the action of the spring, remains in contact with the inspection head, resulting in a cleaner surface and ensuring clear inspection.

[0004] While the above solution can clean the surface of the inspection head and ensure the clarity of the inspection, the different inner diameters of the tubes to be inspected inside the car engine cause the endoscope probe to easily shift under the combined effects of gravity and uneven tubes. Frequent collisions with the tube walls can lead to lens scratches, sensor damage, and other malfunctions. Furthermore, the shift can cause the acquired carbon deposit images to be tilted and blurred, affecting the inspection results. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an endoscope assembly for treating carbon buildup inside automobiles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an endoscope assembly for treating carbon buildup inside an automobile, comprising a probe body, a camera body fixedly connected to the lower end of the probe body, an outer cover column fixedly connected to the outer end of the probe body, multiple sets of transverse telescopic columns fixedly connected to the outer end of the outer cover column, the multiple sets of transverse telescopic columns being arranged in a ring at equal intervals, a spring sleeved on the outer end of each transverse telescopic column, an L-shaped vertical plate fixedly connected to the end of one set of transverse telescopic columns away from the outer cover column, an arc-shaped groove formed on the vertical end of the L-shaped vertical plate away from the outer cover column, symmetrically fixedly connected to limit brackets on both sides of the inner end of the arc-shaped groove, a rolling wheel rotatably connected between the set of limit brackets, and conical anti-scraping strips symmetrically fixedly connected to the upper and lower inner walls of the arc-shaped groove.

[0007] Preferably, the conical anti-scraping strip and the outer wall of the rolling wheel cooperate with each other, and a fixing top ring is fixedly connected to the upper end of the outer cover column.

[0008] Preferably, the lower end of the fixed top ring is fixedly connected to a plurality of vertical telescopic columns, which are arranged in a ring at equal intervals.

[0009] Preferably, the lower ends of the plurality of vertical telescopic columns are fixedly connected to limit locking bottom rings, and a guide slope is provided on the upper side of the vertical end of the L-shaped vertical plate.

[0010] Preferably, the limiting locking bottom ring is sleeved on the outer side of multiple L-shaped vertical plates through multiple guide bevels, and a connecting wire is fixedly connected to the upper end of the probe body.

[0011] Preferably, a controller is fixedly connected to the end of the connecting wire away from the probe body, and a display terminal is externally connected to the controller.

[0012] Preferably, the probe body extends into the inner tube of the vehicle to be tested, and the plurality of rolling wheels and the inner sidewall of the inner tube of the vehicle to be tested are slidably connected to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the cooperation of an L-shaped vertical plate and a horizontal telescopic column, can adapt to changes in the inner diameter of the tube inside the vehicle to be tested, ensuring that the rolling wheel always fits against the inner wall of the tube. This provides a reliable centering guide for the vertical downward movement of the probe body, avoiding deviation and collision with the tube wall that could cause damage to components, and ensuring the clarity of subsequent carbon deposit image acquisition.

[0014] By leveraging the linkage between the conical anti-scraping strip and the rolling wheel, carbon deposits on the wheel surface can be scraped off in real time, preventing carbon buildup from hindering rolling, significantly reducing movement resistance and component wear, and further ensuring a smooth and efficient testing process.

[0015] When the component is not in use, the vertical telescopic column between the fixed top ring and the limiting locking bottom ring can be flexibly lengthened. With the guide slope of the L-shaped vertical plate, the limiting locking bottom ring can be easily placed on the outside of multiple L-shaped vertical plates to securely store the horizontal telescopic column and L-shaped vertical plate, preventing the component from being deformed or damaged by external force collision when it is not in use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 5 As shown, this utility model provides an endoscope assembly for carbon buildup inside automobiles, including a probe body 1. A camera body 16 is fixedly connected to the lower end of the probe body 1. A connecting wire 11 is fixedly connected to the upper end of the probe body 1. A controller 12 is fixedly connected to the end of the connecting wire 11 away from the probe body 1. A display terminal is externally connected to the controller 12. An external cover column 2 is fixedly connected to the outer end of the probe body 1. Multiple sets of transverse telescopic columns 3 are fixedly connected to the outer end of the external cover column 2. The multiple sets of transverse telescopic columns 3 are arranged in a ring at equal intervals. A spring 4 is sleeved on the outer end of the transverse telescopic column 3. An L-shaped vertical plate 5 is fixedly connected to the end of one set of transverse telescopic columns 3 away from the external cover column 2. An arc-shaped groove 17 is opened on the side of the vertical end of the L-shaped vertical plate 5 away from the external cover column 2. Limiting brackets 14 are symmetrically fixedly connected to both sides of the inner end of the arc-shaped groove 17. Rolling wheels 6 are rotatably connected between the sets of limiting brackets 14.

[0020] The above solution is adopted: When the camera body 16 is in actual operation, it illuminates the carbon deposit through the supplementary light module. The reflected light is focused onto the CMOS sensor by the lens group and converted into an electrical signal. After the signal processing unit optimizes the signal, it is transmitted to the controller 12 through the connecting wire 11 to realize the real-time output of a clear image of the carbon deposit. In addition, the horizontal telescopic column 3 is made of high-strength aluminum alloy and forms an elastic telescopic structure with the spring 4 sleeved on the outside. The ring-shaped equidistant distribution design makes the probe body 1 subjected to balanced force and avoids the displacement caused by unilateral force. like Figures 2 to 4As shown, tapered anti-scraping strips 15 are symmetrically fixedly connected to the upper and lower inner walls of the arc-shaped groove 17. The tapered anti-scraping strips 15 and the outer walls of the rolling wheel 6 cooperate with each other. The probe body 1 extends into the inner tube 13 of the vehicle to be tested. Multiple rolling wheels 6 and the inner walls of the inner tube 13 of the vehicle to be tested are slidably connected to each other.

[0021] Using the above solution: The conical back scraper 15 is made of wear-resistant silicone material. When the rolling wheel 6 slides in contact with the inner wall of the inner tube 13 of the vehicle to be tested, the rolling wheel 6 rotates and causes the carbon deposits on the surface to rub against the conical back scraper 15, so that the probe can still move smoothly in the pipe with a lot of oil and carbon deposits.

[0022] like Figures 2 to 5 As shown, a fixed top ring 7 is fixedly connected to the upper end of the outer cover column 2, and multiple vertical telescopic columns 8 are fixedly connected to the lower end of the fixed top ring 7. The multiple vertical telescopic columns 8 are arranged in a ring at equal intervals. A limiting locking bottom ring 9 is fixedly connected to the lower end of the multiple vertical telescopic columns 8. A guide slope 10 is opened on the upper side of the vertical end of the L-shaped vertical plate 5. The limiting locking bottom ring 9 is sleeved on the outer side of the multiple L-shaped vertical plates 5 through the multiple guide slopes 10.

[0023] The above scheme is adopted: the vertical telescopic column 8 adopts a multi-level nested structure, and the telescopic stroke can be flexibly adjusted according to the storage position of the L-shaped vertical plate 5. The inner wall of the limiting locking bottom ring 9 is provided with an inclined surface that matches the guide slope 10. The inclination angle is 30 degrees, so that the bottom ring is automatically guided along the slope during the installation process, reducing the difficulty of operation.

[0024] Working principle and usage process of this utility model: Firstly, during the detection phase, the controller 12 controls the entire assembly via the connecting wire 11. The camera body 16 at the lower end of the probe body 1 moves smoothly with the probe body 1, clearly capturing images of carbon deposits inside the vehicle's internal pipe 13. The captured images are transmitted to the controller 12 in real time via the connecting wire 11, ultimately achieving accurate detection of carbon deposits inside the vehicle. Before operation, the operator can hold multiple L-shaped vertical plates 5, align the probe body 1 with the entrance of the vehicle's internal pipe 13, extend the probe body 1 into the internal pipe 13, and then release the L-shaped vertical plates 5. Because the spring 4 at the outer end of the transverse telescopic column 3 has elastic telescopic characteristics, the extension length of the transverse telescopic column 3 can be adaptively adjusted according to the inner diameter of the inner tube 13 of the vehicle to be tested, thereby driving the L-shaped vertical plate 5 connected to the transverse telescopic column 3 to move synchronously, so that the rolling wheel 6 in the arc groove 17 on the L-shaped vertical plate 5 always maintains sliding contact with the inner wall of the inner tube 13 of the vehicle to be tested. This structure works together to achieve the centering guidance when the probe body 1 extends into the inner tube 13 of the vehicle to be tested and moves vertically downward, thus achieving reliable centering guidance when the probe moves vertically downward and avoiding damage caused by offset collision with the tube wall. Meanwhile, the conical anti-scraping strips 15 on the upper and lower inner walls of the arc groove 17 are in close contact with the outer wall of the rolling wheel 6. During the rotation of the rolling wheel 6, the carbon deposits attached to the surface can be scraped off in real time, effectively preventing the accumulation of carbon deposits from affecting the rolling effect and ensuring that the probe body 1 moves smoothly. When the component is not in use, the vertical telescopic column 8 between the fixed top ring 7 and the limiting locking bottom ring 9 can be flexibly adjusted in length. Together with the guide slope 10 on the L-shaped vertical plate 5, the limiting locking bottom ring 9 is stably fitted on the outside of multiple L-shaped vertical plates 5, so that the horizontal telescopic column 3 and the L-shaped vertical plate 5 are securely stored, making it convenient for the component to be stored and used again.
