Description

[0001] Priority application

[0002] This application claims priority to Chinese Utility Model Patent Application No. 202411996558X, filed on December 31, 2024, entitled "[Title: An Intelligent Inspection Vehicle and Its Collision Avoidance Device]", which is incorporated herein by reference in its entirety. Technical Field

[0003] This utility model relates to the field of intelligent inspection vehicle technology, specifically to an anti-collision device for an intelligent inspection vehicle and an intelligent inspection vehicle. Background Technology

[0004] Traditional manual inspection methods are increasingly unable to meet the demands of modern industry for high-efficiency and high-safety inspections. Manual inspections are not only labor-intensive and time-consuming, but also prone to errors and omissions, especially in high-pressure, high-temperature, or toxic environments, where they can pose a threat to personnel safety. With the continuous advancement of IoT and AI technologies, intelligent inspection vehicles, with their high efficiency, safety, and low cost, are gradually replacing traditional manual inspection methods. Intelligent inspection vehicles can meet the needs of modern industry for automated and intelligent inspections, improving safety and efficiency, reducing costs, and intelligently addressing challenges in complex environments.

[0005] However, during the inspection process, intelligent inspection vehicles inevitably encounter various obstacles, such as walls, pillars, and pipes. Therefore, various intelligent inspection vehicles on the market have been equipped with anti-collision mechanisms.

[0006] For example, Chinese invention patent application CN118478817A discloses a collision avoidance device for inspection vehicles, including: a collision protection mechanism, a forward blocking mechanism, and an anti-rollover mechanism; the collision protection mechanism includes a collision plate and a buffer support; the forward blocking mechanism includes a side push rod fixedly connected to the surface of the collision plate and a blocking disc disposed on both sides of the inspection vehicle body; the anti-rollover mechanism includes a central shaft fixedly connected to the side push rod and a counterweight block disposed at the bottom of the inspection vehicle body; by setting up the collision protection mechanism, when the inspection vehicle body collides with an obstacle, the collision plate releases the impact force received by the collision plate to both sides of the inspection vehicle body through the sliding sleeve and the buffer support, thereby buffering the impact force received by the collision plate and preventing the impact force from acting directly on the inspection vehicle body, thus reducing the damage to the inspection vehicle body when colliding with an obstacle.

[0007] For example, Chinese invention patent CN116533914B discloses a patrol vehicle anti-collision device, which includes a patrol vehicle body; a protective component including a protective frame disposed outside the patrol vehicle body, a groove formed on the outer wall of the protective frame, a damper disposed between the protective frame and the patrol vehicle body, a first elastic member disposed on the outer wall of the damper, and a movable channel formed at one end of the protective frame; a stabilizing component including a second elastic member disposed on the outer wall of the patrol vehicle body and a pressure plate disposed at one end of the second elastic member; and a pressure-bearing component including a baffle movably disposed inside the movable channel. This invention can effectively protect the patrol vehicle body by setting a protective frame to prevent damage. When the patrol vehicle body hits an obstacle, the pressure plate presses down and contacts the ground, improving grip and reducing the risk of rollover. Moreover, the baffle can rise to expand the protection range, disperse the impact force, and protect the vehicle body.

[0008] For example, Chinese utility model patent CN215706776U discloses an intelligent video inspection vehicle based on Mesh networking, relating to the field of inspection equipment technology. It includes an inspection vehicle body and an anti-collision mechanism. Connecting seats are provided on both sides of the inspection vehicle body. An intelligent inspection system is installed inside the inspection vehicle body, including a main controller, a wireless communication module, a network camera module, a sensor module, a relay module, and a power supply module. The anti-collision mechanism includes anti-collision frames located on both sides of the inspection vehicle body, with a mounting plate movably installed on one side of each anti-collision frame inside the connecting seat. By setting up the inspection vehicle body and the anti-collision mechanism, when the inspection vehicle body malfunctions and collides, the anti-collision frame drives the movable cylinder to work with the stabilizing cylinder to compress the spring for buffering. Simultaneously, the connecting rod abuts against the pressure plate, pressing the emergency stop button, causing the inspection vehicle body to stop moving, avoiding subsequent collisions and reducing damage to the inspection vehicle body.

[0009] However, the aforementioned collision avoidance mechanisms only consider collision avoidance in front of or behind the inspection vehicle, while ignoring collision avoidance on the left and right sides. Therefore, there is currently a lack of a collision avoidance structure that can achieve all-round collision avoidance in all directions. Utility Model Content

[0010] The purpose of this utility model is to provide an anti-collision device for an intelligent inspection vehicle and an intelligent inspection vehicle, so as to partially solve or alleviate the problems mentioned in the background art to a certain extent. It comprehensively considers anti-collision in multiple directions such as front, rear, left and right, and sets up a multi-level anti-collision structure considering different impact degrees.

[0011] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution:

[0012] A collision avoidance device for an intelligent inspection vehicle includes a primary collision avoidance structure and a secondary collision avoidance structure disposed around the intelligent inspection vehicle. The primary collision avoidance structure is fitted over the secondary collision avoidance structure. The primary collision avoidance structure is a collision avoidance strip made of flexible material. The secondary collision avoidance structure includes a collision avoidance body disposed around the intelligent inspection vehicle and multiple collision avoidance holes disposed on the collision avoidance body. Multiple sets of warning lights are disposed around the intelligent inspection vehicle. Multiple pressure sensors are disposed within the primary collision avoidance structure, and each set of warning lights corresponds to one pressure sensor.

[0013] The anti-collision device for the intelligent inspection vehicle provided by this utility model can reduce the impact on the inspection vehicle during a collision by setting a primary anti-collision structure made of flexible material and a secondary anti-collision structure with multiple anti-collision holes. By setting pressure sensors in the primary anti-collision structure and setting warning lights corresponding to each pressure sensor, the collision location can be accurately indicated, reducing the risk of damage to the inspection vehicle.

[0014] Furthermore, the plurality of pressure sensors are arranged along the length of the primary anti-collision structure.

[0015] Furthermore, the anti-collision strip includes a base extending along its length and an arc-shaped buffer strip, which together enclose a sealed accommodating space in the same longitudinal section, within which the pressure sensor is installed. Specifically, multiple pressure sensors are evenly arranged on the base.

[0016] Furthermore, the anti-collision body is the outer shell of the inspection vehicle. Specifically, the anti-collision body can be integrally formed with the outer shell, or it can be detachably installed on the outer shell.

[0017] Furthermore, the anti-collision hole is a perforated hole that penetrates the anti-collision body along the height direction of the anti-collision body.

[0018] Furthermore, the anti-collision hole is triangular in shape.

[0019] Furthermore, the anti-collision hole includes a first anti-collision hole located on the front and rear sides opposite to each other on the anti-collision body and a second anti-collision hole located on the left and right sides opposite to each other on the anti-collision body, wherein the size of the first anti-collision hole is larger than that of the second anti-collision hole.

[0020] Furthermore, the warning light is located above the primary anti-collision structure.

[0021] Furthermore, the warning light is an LED light strip.

[0022] Based on the aforementioned anti-collision device, this utility model also provides an intelligent inspection vehicle, which includes the aforementioned anti-collision device. Specifically, the anti-collision body of the anti-collision device can be integrally formed with the outer shell of the intelligent inspection vehicle, or can be detachably installed around the outer shell of the intelligent inspection vehicle.

[0023] Beneficial effects: This utility model sets up a two-level anti-collision structure. For example, for minor collisions, a first-level anti-collision structure is set up, such as an anti-collision strip made of flexible materials such as rubber. At the same time, a second-level anti-collision structure is set up, such as a hollow anti-collision hole structure around the perimeter of the vehicle body, to reduce the impact in the event of a major collision, which greatly improves the anti-collision effect.

[0024] Furthermore, pressure sensors and multiple sets of warning lights are installed. Once the pressure sensor detects a collision, the corresponding set of warning lights will illuminate, thereby improving the visibility and safety of nighttime inspections. At the same time, the hollowed-out anti-collision strip design can buffer the impact force and accurately indicate the collision location when a collision occurs, reducing the risk of damage to the inspection vehicle and the surrounding environment, improving inspection efficiency and safety, reducing the need for manual inspections, lowering costs, and improving the response speed and processing efficiency of inspections through automation and intelligent technologies.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this document, "and / or" includes any and all combinations of one or more of the listed related items.

[0037] In this article, "multiple" means two or more, that is, it includes two, three, four, five, etc.

[0038] See Figures 1 to 4This utility model provides a collision avoidance device for an intelligent inspection vehicle. The intelligent inspection vehicle includes an inspection vehicle body, and the collision avoidance device includes a primary collision avoidance structure and a secondary collision avoidance structure disposed around the intelligent inspection vehicle 1.

[0039] In some embodiments, the anti-collision device further includes: a plurality of pressure sensors 6 disposed within the primary anti-collision structure, and a plurality of sets of warning lights 5 disposed around the intelligent inspection vehicle 1, wherein each set of warning lights 5 corresponds to one pressure sensor 6 (for example, each set of warning lights is connected to one pressure sensor via circuit or wireless communication). Preferably, the warning lights 5 are LED light strips.

[0040] Preferably, the multiple pressure sensors 6 are arranged along the length of the primary anti-collision structure. More preferably, the interval between two adjacent pressure sensors is 8cm-14cm; preferably 10cm.

[0041] In some embodiments, the primary impact protection structure is an impact protection strip 2 made of a flexible material, such as rubber.

[0042] Preferably, the anti-collision strip 2 includes a base 21 extending along its length and an arc-shaped buffer strip 22, which together enclose a sealed accommodating space 23 in the same longitudinal section. Preferably, the accommodating space 23 is used to install the aforementioned pressure sensor 6.

[0043] In some embodiments, the secondary anti-collision structure includes an anti-collision body 3 disposed around the intelligent inspection vehicle 1, and a plurality of anti-collision holes 4 disposed on the anti-collision body 3.

[0044] In some embodiments, the anti-collision body 3 is the outer shell of an intelligent inspection vehicle.

[0045] In some embodiments, the anti-collision hole 4 is a perforated hole that penetrates the anti-collision body 3 along the height direction of the anti-collision body 3.

[0046] In some embodiments, the anti-collision hole 4 is triangular.

[0047] Furthermore, to ensure both the structural stability of the anti-collision body and its anti-collision capability, in some embodiments, the directions of two adjacent triangular anti-collision holes 4 are opposite. That is, the tip of one of the two adjacent anti-collision holes faces the intelligent inspection vehicle, while the tip of the other anti-collision hole faces the opposite direction. See [link to relevant documentation]. Figure 2 and Figure 4 .

[0048] In some embodiments, the size of the first anti-collision holes 41 located on the front and rear sides of the anti-collision body, respectively, is larger than the size of the second anti-collision holes 42 located on the left and right sides of the anti-collision body, respectively. Generally speaking, the probability of a large collision occurring on the front and rear sides is much greater than that on the left and right sides. Therefore, providing larger anti-collision holes on the front and rear sides can play a greater buffering role.

[0049] In some embodiments, the warning light 5 is located above the primary anti-collision structure. Here, "above" means that the height of the warning light in the vertical plane is higher than the height of the primary anti-collision structure in the vertical plane.

[0050] See Figure 3 In some embodiments, the cross-section of the anti-collision body 3 is trapezoidal, with its bottom edge installed on the outer shell of the intelligent inspection vehicle, and a mounting groove for installing a warning light is provided on the top edge 30 of the trapezoid near the first inclined edge 31. This installation method reduces the obstruction of the driver's line of sight to a certain extent due to the presence of the first inclined edge 31, allowing the driver to more clearly identify the specific area of ​​the warning light embedded in the anti-collision body 3.

[0051] Furthermore, a mounting groove for installing the anti-collision strip 2 is provided on the top edge 30 of the trapezoid 30 near the second inclined side 32. A protrusion extends from the base 21 of the anti-collision strip 2, closer to the anti-collision body 3, away from the base 21. Through the cooperation of this protrusion and the mounting groove, the anti-collision strip 2 is installed on the anti-collision body 3 and protrudes beyond it, thus forming a two-level anti-collision system in the horizontal direction. Additionally, placing the anti-collision strip below the warning light also prevents it from obstructing the light and obstructing the driver's view of the warning light area.

[0052] See Figure 3 In order to improve the buffer between the two-stage anti-collision structure, the distance between the anti-collision hole 4 and the top edge 30 of the trapezoid is greater than the distance between the anti-collision hole and the bottom edge of the trapezoid. That is, the distance between the anti-collision hole and the anti-collision strip is greater, so that the anti-collision body between the two can absorb part of the impact, thereby avoiding the situation where there is not enough buffer structure between the two to absorb the impact because the anti-collision hole is too close to the anti-collision strip.

[0053] In some embodiments, circuit boards for the warning light and pressure sensor can be pre-embedded in the anti-collision body. Alternatively, a pressure sensor and a warning light with wireless communication function can be used respectively.

[0054] Based on the aforementioned anti-collision device, this utility model also provides an intelligent inspection vehicle, which includes the anti-collision device of the above embodiment. Specifically, the bottom of the anti-collision body 3 is provided with a mounting plate 35, through which the anti-collision body 3 can be detachably mounted on the outer shell of the intelligent inspection vehicle. Of course, in some other embodiments, the anti-collision body 3 can also be integrally formed with the outer shell of the inspection vehicle.

[0055] In this embodiment, by installing light strips around the vehicle body as warning lights, not only is nighttime visibility enhanced, but the flashing light signals also indicate the location, ensuring safety during nighttime operations. For example, the anti-collision strip 2 (i.e., the primary anti-collision structure) contains a pressure sensor 6. Once a collision occurs at a certain location, a set of warning lights 5 (i.e., light strips) corresponding to the pressure sensor 6 will immediately illuminate to quickly indicate the area of ​​impact, facilitating timely detection of the collision. Furthermore, the hollowed-out buffer structure design of the secondary anti-collision structure effectively absorbs impact force, reducing damage to the vehicle and the surrounding environment, and improving the durability and reliability of the inspection vehicle.

[0056] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0057] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims.
