Generally, the wheel guard should be sufficient to cover the entire tire within the area formed by two radial planes, one 30° forward and one 50° backward from the wheel center.

[0003] In related technologies, tools such as measuring tapes, plumb lines, levels, and angle gauges are used to detect the distance between the wheel guard and the wheel in the horizontal direction to determine whether the wheel guard is compliant.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0048] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0049] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0050] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0051] In embodiments of this application, 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. Without further limitation, 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.

[0052] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0053] This application provides a vehicle detection device for use with vehicles, which can be large cars, small cars, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles are generally equipped with wheels and wheel guards. The wheel guards are located above the wheels and are used to shield against mud, water, flying stones, etc., thrown out when the wheels are rotating.

[0054] Currently, traditional methods for inspecting wheel guards rely solely on measuring tapes, plumb lines, levels, and angle gauges. These methods are not only inconvenient for visually assessing the results, but also highly susceptible to operator error and environmental factors, leading to inaccuracies, large errors, and low efficiency. While specialized equipment exists that offers higher precision, it is more complex to operate and more expensive.

[0055] To address the aforementioned issues, this application provides a vehicle inspection device comprising a support mechanism and an inspection component. The inspection component is rotatably mounted on the support mechanism with its rotation axis positioned horizontally. When the rotation axis of the inspection component is close to the wheel axle of the vehicle under test, and the support mechanism is in contact with the outer side of the wheel, the wheel guard of the vehicle under test drives the inspection component to move along the rotation axis to detect the distance between the outer side of the wheel and the outer side of the wheel guard. In other words, by acquiring the displacement of the inspection component relative to the support mechanism along the rotation axis, the distance between the outer side of the wheel and the outer side of the wheel guard is measured. This allows for a direct and effective detection of whether the wheel guard is compliant, thereby ensuring inspection efficiency.

[0056] The vehicle detection device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0057] Please refer to Figures 1-3 As shown, this application provides a vehicle detection device, including a support mechanism 100 and a detection component 200. The detection component 200 is rotatably mounted on the support mechanism 100, and the rotation axis of the detection component 200 is horizontally set.

[0058] The detection component 200 is configured such that when the rotation axis of the detection component 200 is close to the axis of the wheel 10 of the vehicle under test, and the support mechanism 100 is in contact with the outer side of the wheel 10, the wheel guard 20 of the vehicle under test drives the detection component 200 to move along the rotation axis direction, so as to detect the distance between the outer side of the wheel 10 and the outer side of the wheel guard 20.

[0059] In this embodiment, the support mechanism 100 is used to support and position the detection component 200, and it can be a support rod, support base, support frame, or a combination structure. Furthermore, in use, the support mechanism 100 is placed on one side of the wheel 10 of the vehicle under test and can be stably placed on the foundation.

[0060] In this embodiment, the detection component 200 is used to contact the outer surface of the wheel guard plate 20 of the vehicle under test. It can be a detection plate, detection rod, detection ruler, etc., and can be a long strip structure. The detection component 200 can be connected to the support mechanism 100 via a rotating structure such as a shaft or pin, ensuring that the detection component 200 can rotate around and move along the horizontal axis. Figure 1 Rotate along the X-axis, and can also move along Figure 1 Move along the X-axis.

[0061] Specifically, such as Figure 3 As shown, the support mechanism 100 is first moved to the side of the wheel 10 of the vehicle under test. The detection component 200 is moved and rotated relative to the support mechanism 100 to adjust to the initial position. When the rotation axis of the detection component 200 is close to the axis of the wheel 10 of the vehicle under test, and the support mechanism 100 is close to and in contact with the lower part of the outer side of the wheel 10, the detection component 200 contacts the outer side of the wheel guard plate 20 of the vehicle under test. The wheel guard plate 20 drives the detection component 200 to move along the rotation axis, so that the detection component 200 and the support mechanism 100 generate relative displacement in the axial direction, thereby realizing the detection of the distance between the outer side of the wheel 10 and the outer side of the wheel guard plate 20.

[0062] Furthermore, the detection component 200 can be manually driven to deflect at a preset angle relative to the wheel 10. For example, taking the vertical plane where the axis of the wheel 10 is located as a reference, it can be deflected 30° in front of the axis of the wheel 10 and 50° behind the axis of the wheel 10. During this process, if the relative displacement between the detection component 200 and the support mechanism 100 is less than the specified value, the wheel guard plate 20 is determined to be non-compliant.

[0063] It should be noted that markings, such as lines or scales, can also be set between the rotation axis of the detection component 200 and the support mechanism 100 to make it easier to read the relative displacement between the two.

[0064] It is understandable that, compared to tools or methods such as measuring tapes, plumb lines, levels, and angle meters for inspection, the vehicle inspection device provided in this application, by acquiring the displacement of the inspection component 200 relative to the support mechanism 100 along the rotation axis, measures the distance between the outer side of the wheel 10 and the outer side of the wheel guard 20, which can intuitively and effectively detect whether the wheel guard 20 is compliant, thereby ensuring inspection efficiency. Moreover, it is more accurate, simple to operate, convenient to use, easier to process and manufacture, and lower in cost.

[0065] It should be noted that the rotation axis of the detection component 200 is close to the axis of the wheel 10. That is, the rotation axis of the detection component 200 is coaxial with the axis of the wheel 10, or the coaxiality between the rotation axis of the detection component 200 and the axis of the wheel 10 is within a preset range. The goal is to make the rotation axis of the detection component 200 coincide with the axis of the wheel 10 as much as possible. Moreover, the preset angle can also be determined according to actual needs.

[0066] Therefore, the vehicle detection device provided in this application includes a support mechanism 100 and a detection component 200. By rotatably mounting the detection component 200 on the support mechanism 100 and setting the rotation axis of the detection component 200 in the horizontal direction, when the rotation axis of the detection component 200 is close to the axis of the wheel 10 of the vehicle under test and the support mechanism 100 is in contact with the outer side of the wheel 10, the wheel guard plate 20 drives the detection component 200 to move along the rotation axis direction to detect the distance between the outer side of the wheel 10 and the outer side of the wheel guard plate 20. That is, by obtaining the displacement of the detection component 200 relative to the support mechanism 100 in the rotation axis direction, the distance between the outer side of the wheel 10 and the outer side of the wheel guard plate 20 is measured, which can intuitively and effectively detect whether the wheel guard plate 20 is compliant, thereby ensuring detection efficiency.

[0067] In some embodiments of this application, the support mechanism 100 includes a first connector 110, and the detection component 200 includes a second connector 210.

[0068] One of the second connector 210 and the first connector 110 is inserted into the other, and the second connector 210 rotates and moves relative to the first connector 110, and the second connector 210 is horizontally positioned.

[0069] Specifically, such as Figure 2As shown, the first connecting member 110 can be a connecting rod, a connecting block, a connecting plate, etc., and correspondingly, the second connecting member 210 can also be a connecting rod, a connecting block, a connecting plate, etc. On one hand, the second connecting member 210 can be inserted horizontally onto the first connecting member 110, and it can rotate about a horizontal axis and move along that horizontal axis. On the other hand, the first connecting member 110 can also be inserted horizontally onto the second connecting member 210, and it can rotate about a horizontal axis and move along that horizontal axis.

[0070] For example, in this embodiment, the first connector 110 has a slot 111 that matches a portion of the second connector 210, and the portion of the second connector 210 is inserted into the slot 111 and moves along the extension direction of the slot 111.

[0071] With this configuration, the cross-section of the slot 111 is partially circular, and at least part of the cross-section of the second connector 210 is a circle that matches the slot 111. Through the insertion between the second connector 210 and the slot 111, the second connector 210 can move within the slot 111 along its extension direction and rotate around the extension direction of the slot 111, which facilitates manufacturing, installation, and adjustment, and the structure is simple and reliable.

[0072] Of course, the slot 111 can also be located on the second connector 210, with part of the first connector 110 matching the slot 111 and being inserted into the slot 111, and moving along the extension direction of the slot 111. This also enables the insertion between the first connector 110 and the second connector 210, while ensuring relative rotation and movement.

[0073] In addition, the first connecting member 110 and the second connecting member 210 can also be replaced by other types of rotating structures, which can be determined according to actual needs. This embodiment does not impose too many restrictions.

[0074] Furthermore, in this embodiment, the second connector 210 is a cylinder, and the slot 111 is an arc-shaped groove that matches the second connector 210. The opening of the slot 111 faces upward, and the central angle corresponding to the slot 111 is at least 80°. That is, the central angle corresponding to the second connector 210 being deflected from one side of the arc-shaped groove to the other side of the arc-shaped groove is greater than or equal to 80°.

[0075] Specifically, such as Figure 2 As shown, the opening of the arc-shaped groove faces upward, and its cross-section can be semi-circular, etc. The cylinder fits into the arc-shaped groove, which facilitates manufacturing and installation. The edges on both sides of the arc-shaped groove can be used to limit the rotation angle of the second connector 210. The angle through which the second connector 210 deflects from the extreme position on one side of the arc-shaped groove to the extreme position on the other side of the arc-shaped groove should be greater than or equal to 80°.

[0076] In particular, relative to the vertical plane, the angle corresponding to the extreme position of the second connector 210 from the position of the vertical plane to one side of the arc groove should be greater than or equal to 30°, and the angle corresponding to the extreme position of the second connector 210 from the position of the vertical plane to the other side of the arc groove should be greater than or equal to 50°, so as to meet the testing requirements.

[0077] The specific shape and size of the arc groove can be determined according to actual needs, and this embodiment does not impose too many restrictions.

[0078] Furthermore, in this embodiment, the first connector 110 has at least one limiting part 112, which is located on the slot 111 and is used to restrict the movement of the second connector 210.

[0079] Specifically, such as Figure 1 , Figure 2 As shown, the upper part of the slot 111 is provided with at least one limiting part 112. The limiting part 112 and the arc groove form a circular cross section. On the one hand, it facilitates the movement of the second connector 210 within the cavity formed by the limiting part 112 and the arc groove, ensuring stability. On the other hand, the limiting part 112 can also axially restrict the second connector 210, preventing the second connector 210 from sliding off one side of the arc groove.

[0080] In some embodiments of this application, the detection component 200 further includes a detection element 220 connected to the second connector 210. The detection element 220 extends in a direction perpendicular to the rotation axis of the second connector 210 and is used to contact the outer side of the guard plate 20.

[0081] Specifically, such as Figure 2 As shown, the detection component 220 can be a detection plate, detection rod, detection ruler, etc., and can be a long strip structure. Its length extension direction is perpendicular to the rotation axis of the second connecting component 210. The detection component 220 and the second connecting component 210 can be connected and fixed by welding, snap-fitting, screwing, etc. During detection, the detection component 220 contacts the outer side of the wheel guard plate 20 of the vehicle under test.

[0082] This design makes the structure simpler and lighter, and easier to manufacture and process. The specific shape and specifications of the second connector 210 and the detection component 220 can be determined according to actual needs, and no specific limitation is made in this embodiment.

[0083] Furthermore, in this embodiment, a first measuring element 221 is provided on the detection element 220, and the first measuring element 221 is used to measure the deflection angle of the detection element 220.

[0084] Specifically, such as Figure 2As shown, the first measuring element 221 is used to measure the deflection angle of the detection element 220. It can be an angle meter, angle ruler, protractor, etc., preferably an electronic angle meter. It can be connected to one side of the detection element 220 by means of bonding, screwing, snapping, etc.

[0085] This allows for a more convenient and faster reading of the current deflection angle value of the detection element 220. The specific type and location of the first measuring element 221 can be determined according to actual needs; this embodiment does not impose excessive restrictions.

[0086] In some embodiments of this application, the support mechanism 100 further includes a base 120 and a telescopic assembly 130, the telescopic assembly 130 being erected on the base 120 and used to contact the outer side of the wheel 10.

[0087] The first connector 110 is connected to the telescopic assembly 130, which is used to adjust the height of the first connector 110.

[0088] Specifically, such as Figure 1 , Figure 2 As shown, the base 120 serves as a stable support and can be a plate-shaped, block-shaped, or shell-shaped structure. The bottom surface of the base 120 is flat and can be placed stably on the ground. The telescopic component 130 is used to adjust the height of the first connecting member 110, i.e., the height of the rotation axis of the detection component 200. It can be a telescopic rod, telescopic frame, etc. The telescopic component 130 is set vertically, with its lower end fixedly connected to the base 120 and its upper end fixedly connected to the first connecting member 110.

[0089] In this way, the height of the rotation axis of the second connector 210 relative to the axis of the wheel 10 of the vehicle under test can be easily adjusted by extending and retracting the telescopic component 130. The specific shape and size of the base 120, as well as the type and specifications of the telescopic component 130, can be determined according to actual needs, and are not specifically limited in this embodiment.

[0090] Furthermore, in this embodiment, the telescopic assembly 130 includes a first rod 131 and a second rod 132. The first rod 131 is erected on the base 120 and is used to contact the outer side of the wheel 10.

[0091] The first rod 131 is provided with a socket 1311, and part of the second rod 132 is inserted into the socket 1311.

[0092] The first connector 110 is connected to the second rod 132, driving the second rod 132 to move along the extension direction of the first rod 131 to adjust the height of the first connector 110.

[0093] Specifically, such as Figure 2As shown, the first rod 131 is erected, and its lower end is fixedly connected to the base 120. The upper end of the first rod 131 has a socket 1311, and the lower end of the second rod 132 matches the socket 1311. The two are inserted together, and the second rod 132 can move vertically relative to the socket 1311. Figure 1 As shown in the Z-axis direction.

[0094] Of course, the insertion hole can also be located at the lower end of the second rod 132, with the upper end of the first rod 131 matching the insertion hole 1311, thus achieving the insertion between the two. It should be noted that when the first rod 131 and the second rod 132 are inserted, their free movement can be restricted by a tight fit or locking mechanism.

[0095] Furthermore, a telescopic component composed of more rods can be provided, or it can be replaced by other types of structures. The specific lengths and specifications of the first rod 131 and the second rod 132 can be determined according to actual needs, and no excessive restrictions are imposed in this embodiment.

[0096] Furthermore, in this embodiment, the telescopic assembly 130 also includes a locking member 133, which is disposed on at least one of the first rod 131 and the second rod 132, and is used to lock or unlock the insertion hole 1311 and the second rod 132.

[0097] For example, such as Figure 1 , Figure 2 As shown, the locking element 133 can be a locking bolt, which can be threaded onto the first rod 131 and extends into the insertion hole 1311. In this way, the lower end of the second rod 132 can be locked or unlocked by turning the locking bolt.

[0098] Of course, the locking element 133 can also be replaced by other types of locking components, such as a tightening sleeve, etc. Any component that can facilitate locking or unlocking between the insertion hole 1311 and the second rod 132 can be used, depending on actual needs. This embodiment does not impose too many restrictions.

[0099] Furthermore, in this embodiment, a second measuring element 121 is provided on the base 120, which is used to measure the levelness of the base 120.

[0100] Specifically, continue as Figure 1 As shown, the second measuring component 121 is used to measure the levelness of the base 120 and determine whether the base 120 is level. It can be a level or a spirit level. The second measuring component 121 can be connected to the base 120 by means of bonding, screwing, snapping, etc.

[0101] This makes it easier and faster to determine whether the base 120 is level, thus facilitating adjustments. The specific type and location of the second measuring element 121 can be determined according to actual needs; this embodiment does not impose excessive restrictions.

The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
