Description

Technical Field

[0001] This invention relates to the technical field of tire tread detection equipment, and more specifically, to a tire tread detection device. Background Technology

[0002] Inspection of tire tread patterns is of great significance to vehicle driving safety. The depth, width, and shape of the tire tread pattern affect the friction of the tire surface. Therefore, it is necessary to inspect tire tread patterns regularly.

[0003] Current tire tread detection devices require the inspector to squat down to the tire and insert the device into the gap between the bumper and the ground. During this process, the inspector's hand is always in a position where it is difficult to apply force, and the operation method is not ergonomic. Therefore, it is difficult to ensure that the tire plate and the tire tread detection device make full contact, and the device is prone to tilting relative to the tire surface, resulting in low detection accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a tire tread detection device to solve the technical problems in the prior art where the tire tread detection device is difficult to ensure full contact between the tire plate and the tire tread detection device due to its design, and the tire tread detection device is prone to tilting relative to the tire surface, resulting in low detection accuracy.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] In a first aspect, a tire tread detection device is provided, comprising:

[0007] A housing assembly includes a detection housing and a handle housing, wherein the handle housing is capable of moving the detection housing, and the detection housing and the handle housing are arranged at intervals.

[0008] The positioning assembly includes a tire plate disposed on the end of the detection housing and perpendicular to the length direction of the detection housing;

[0009] The detection assembly includes a detection element disposed on the end of the detection housing opposite to the tire plate.

[0010] By adopting the above technical solution:

[0011] First, the test housing and the handle housing are arranged at intervals. This allows the handle housing to remain outside the gap when the tester holds the handle housing and inserts the test housing into the gap between the car bumper and the ground, or to avoid inserting the handle housing too far into the gap. This prevents the tester from being unable to apply force to the test housing, which could cause the tire plate on the test housing to not accurately abut against the tire tread surface or to tilt.

[0012] Secondly, since the tire plate is perpendicular to the length of the detection housing, when the inspector places the tire plate against the tire, the length of the detection housing is perpendicular to the tire surface. At this time, the tire tread detection device has a high degree of accuracy in tire tread detection.

[0013] Finally, the detection element and the tire backing plate are located at opposite ends of the detection housing, so that when the tire backing plate abuts against the tire tread surface, the detection element is at a certain distance from the tire tread surface, keeping the detection element at a suitable detection distance and improving the accuracy of the detection.

[0014] In one embodiment, the length direction of the detection housing is parallel to the length direction of the handle housing.

[0015] By adopting the above technical solution, it is easier for inspectors to adjust the relative position of the tread detection device to the tread surface of the tire to be inspected and to improve the accuracy of the inspection.

[0016] In one embodiment, the housing assembly further includes a rotation shaft connecting the handle housing and the detection housing, the rotation shaft being perpendicular to the length direction of the detection housing, and the handle housing being rotatable about the rotation shaft.

[0017] By adopting the above technical solution, the flexibility of adjustment between the handle housing and the detection housing is improved, and the possibility of the tire tread detection device being affected can be reduced when the detection space is limited.

[0018] In one embodiment, the tire backing plate includes at least two abutting portions and a recessed portion located between two adjacent abutting portions. The abutting portion is a planar structure for abutting against the tire tread surface, and the surface of the abutting portion for abutting against the tire tread surface is planar. The recessed portion is a concave-convex portion for avoiding the tire tread surface, and the recessed portion is recessed inward relative to the abutting portions toward the interior of the tire backing plate.

[0019] By adopting the above technical solution, it is ensured that the tire plate is in close contact with the tire tread surface, reducing the possibility of the tread detection device tilting, thereby reducing detection errors.

[0020] In one embodiment, the tire plate further includes a magnetic part disposed on the abutment portion and used to cooperate with the calibration device.

[0021] By adopting the above technical solution, the fixed connection structure between the tire plate and the calibration device is simple and easy to operate.

[0022] In one embodiment, the positioning assembly further includes a push rod disposed on the detection housing and extending away from the detection housing along the length direction of the detection housing, and the tire plate is disposed on the end of the push rod away from the detection housing.

[0023] By adopting the above technical solution, the tire plate is easier to observe, thus improving the detection efficiency.

[0024] In one embodiment, the positioning assembly further includes a push rod connector that allows the push rod to be detachably connected to the detection housing.

[0025] By adopting the above technical solution, it is easy to replace the top rod and the tire plate. By changing the length of the top rod and the tire plate of different specifications, the applicability of the tire tread detection device can be improved.

[0026] In one embodiment, the detection element includes a laser element and a camera element, the laser element being used to emit a detection laser to form a detection light strip on the surface of the tire tread, and the camera element being used to acquire the detection light strip formed on the surface of the tire tread.

[0027] By adopting the above technical solution, the detection accuracy of the detection element is high.

[0028] In one embodiment, the detection assembly further includes a control board electrically connected to the laser element and the camera element, the control board being disposed within the handle housing, the control board being used to control the laser element and analyze the detection light strip acquired by the camera element.

[0029] By adopting the above technical solution, the volume of the detection housing is reduced, making it easier for the detection housing to be inserted into the gap between the car bumper and the tire.

[0030] In one embodiment, the detection component further includes a display panel and a battery electrically connected to the control board, the display panel being disposed on the surface of the handle housing and the battery being housed inside the handle housing.

[0031] By adopting the above technical solution, the tire tread detection device becomes more suitable for use. Attached Figure Description

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this invention will be described in more detail below with reference to specific embodiments:

[0045] like Figure 1 and Figure 2 As shown in the illustration, this invention provides a tire tread detection device for detecting the depth, width, and shape of tire treads, thereby analyzing tire tread surface information, such as the friction force generated when the tire tread surface contacts the ground. In this embodiment, the inspector holds the tire tread detection device to perform the inspection. Specifically, the inspector inserts the tire tread detection device into the gap between the car bumper and the ground, and then places the tire tread detection device against the surface of the tire. Here, it should be further explained that the surface of the tire with treads is defined as the surface with tire treads in this embodiment. Then, the tire tread detection device is activated for inspection. The tire tread detection device of this embodiment has the advantages of good operability, low tendency to tilt, and high detection accuracy. The following is a detailed description of the specific implementation method:

[0046] The tire tread detection device includes: housing assembly 1, positioning assembly 2, and detection assembly 3;

[0047] The housing assembly 1 includes a detection housing 11 and a handle housing 12. The handle housing 12 can drive the detection housing 11 to move. The detection housing 11 and the handle housing 12 are arranged at intervals. When the inspector uses the tire tread detection device, the detection housing 11 and the handle housing 12 are arranged at intervals along the axial direction of the tire on the tread surface. The detection housing 11 is located on the inner side of the tire for detecting the tread surface, and the handle housing 12 is located on the outer side of the tire or is detached from the tire for the inspector to hold. Here, the housing assembly 1 is used to fix the positioning assembly 2 and the detection assembly 3. The housing assembly 1 includes a detection housing 11 and a handle housing 12, wherein the detection housing 11 is used for... The tire plate 21 and the detection element 31 are fixed together, and the handle housing 12 is used for the inspector to hold. It should be further explained that the detection housing 11 and the handle housing 12 are arranged at intervals, so that there is a certain distance between the inspector and the detection housing 11 when holding the handle housing 12. In this way, the inspector can insert the positioning component 2 and the detection component 3 into the gap between the car bumper and the ground, while the inspector's hand can remain outside the gap. This avoids the inspector's hand being inserted too much, which would prevent the inspector from being able to press the positioning component 2 firmly against the tire tread surface, or the inspector's hand being inserted too much, causing the tire tread detection device to tilt.

[0048] The positioning component 2 includes a tire-adhesive plate 21 disposed at the end of the detection housing 11 and perpendicular to the length direction of the detection housing 11. Here, the positioning component 2 is used to calibrate the position and angle of the tire tread detection device relative to the tire tread surface. Specifically, the positioning component 2 includes the tire-adhesive plate 21, which is used to abut against the tire tread surface. By adjusting the relative position of the tire-adhesive plate 21 and the tire tread surface, the position calibration of the tire detection device is achieved, ensuring the detection accuracy of the tire detection device. It should be further explained that the surface of the tire-adhesive plate 21 is perpendicular to the length direction of the detection housing 11. When the surface of the tire-adhesive plate 21 abuts against the surface of the tire, the length direction of the detection housing 11 is perpendicular to the surface of the tire, and the tire tread detection device has a high accuracy in tire tread detection at this time.

[0049] The detection assembly 3 includes a detection element 31 disposed on the end of the detection housing 11 away from the tire plate 21. Here, the detection assembly 3 is used to detect the pattern on the surface of the tire tread, and the detection method includes, but is not limited to, image recognition detection. In this embodiment, the detection element 31 is a laser element and a camera element. The laser element forms a detection light strip on the surface of the tire tread, and the camera element acquires the image of the light strip and transmits it to the control board for analysis, thereby obtaining information about the tire tread pattern.

[0050] The working steps of the tire tread detection device provided in this embodiment are as follows:

[0051] First, the inspector holds the handle housing 12 and positions the inspection housing 11 toward the tire to be inspected. Second, the inspector inserts the inspection housing 11 into the gap between the car bumper and the ground. Third, the inspector aligns the tire tread plate 21 on the inspection housing 11 with the tire tread surface and presses it against the tire tread surface. Since the tire tread plate 21 is perpendicular to the length direction of the inspection housing 11, the length direction of the inspection housing 11 is perpendicular to the tire tread surface, thus placing the inspection element 31 on the inspection housing 11 in a suitable inspection position.

[0052] By adopting the above technical solution:

[0053] First, the detection housing 11 and the handle housing 12 are arranged at intervals in a direction parallel to the tire tread surface. This allows the handle housing 12 to remain outside the gap when the inspector holds the handle housing 12 and inserts the detection housing 11 into the gap between the car bumper and the ground, or to avoid inserting the handle housing 12 too far into the gap. This prevents the inspector from being unable to apply force to the detection housing 11, which could cause the tire plate 21 on the detection housing 11 to not accurately abut against the tire tread surface or to tilt.

[0054] Secondly, since the tire plate 21 is perpendicular to the length direction of the detection housing 11, when the inspector places the tire plate 21 against the tire tread surface, the length direction of the detection housing 11 is perpendicular to the tire surface, and the tread detection device has a high degree of accuracy in tread detection.

[0055] Finally, the detection element 31 and the tire backing plate 21 are located at opposite ends of the detection housing 11, so that when the tire backing plate 21 abuts against the tire tread surface, the detection element 31 is spaced a certain distance from the tire tread surface, so that the detection element 31 is in a suitable detection distance, thereby improving the accuracy of the detection.

[0056] In one embodiment, the length direction of the detection housing 11 is parallel to the length direction of the handle housing 12.

[0057] In this embodiment, the detection housing 11 and the handle housing 12 are parallel and spaced apart. That is, when the testing personnel hold the handle housing 12, they can adjust the handle housing 12 to be approximately perpendicular to the tire tread surface, which will cause the detection housing 11 to be approximately perpendicular to the tire tread surface. This allows the tire plate 21 to be adjusted to contact the tire tread surface more quickly, thereby causing the detection housing 11 to be perpendicular to the tire tread surface, and finally placing the detection element 31 in a suitable detection position.

[0058] In addition, the length direction of the handle housing 12 is parallel to the length direction of the detection housing 11. Thus, when the inspector holds the handle housing 12 and applies a force parallel to the length direction of the handle housing 12, the force is transmitted from the handle housing 12 to the detection housing 11 and then to the tire plate 21. Since this force is also parallel to the detection housing 11, the tire plate 21 is subjected to a force parallel to the detection housing 11. This design makes it easier for the inspector to determine the direction of their applied force, reduces the possibility of the tire tread detection device tilting, and improves the accuracy of the detection.

[0059] By adopting the above technical solution, it is easier for inspectors to adjust the relative position of the tread detection device to the tread surface of the tire to be inspected and to improve the accuracy of the inspection.

[0060] In one embodiment, the housing assembly 1 further includes a rotating shaft 13 connecting the handle housing 12 and the detection housing 11. The rotating shaft 13 is perpendicular to the length direction of the detection housing 11, and the handle housing 12 is capable of rotating around the rotating shaft 13.

[0061] Preferably, the handle housing 12 is dampedly connected to the rotating shaft 13, meaning that the handle housing 12 can be suspended at a target angle relative to the detection housing 11. In this way, when the detection space is limited, the relative angle between the handle housing 12 and the detection housing 11 can be adjusted to make it easier for the operator to grip the handle housing 12. This allows for better adjustment of the operator's force application point and direction, further reducing the possibility of the tire tread detection device tilting.

[0062] By adopting the above technical solution, the flexibility of adjustment between the handle housing 12 and the detection housing 11 is improved, and the possibility of the tire tread detection device being affected can be reduced when the detection space is limited.

[0063] Please also refer to Figure 3 and Figure 4 In one embodiment, the tire plate 21 includes at least two abutting portions 211 and a recessed portion 212 located between two adjacent abutting portions 211. The abutting portions 211 are planar structures for abutting against the tire tread surface. The surface of the abutting portions 211 for abutting against the tire tread surface is planar. The recessed portion 212 is a concave-convex portion for avoiding the convex-concave surface of the tire tread. The recessed portion 212 is recessed towards the interior of the tire plate 21 relative to the abutting portions 211.

[0064] Here, the design of the tire tread plate 21 can reduce the contact area with the tire tread surface and reduce the impact of the uneven parts of the tire tread surface on the tire tread plate 21. Specifically, the tire tread plate 21 includes an abutting part 211 and a concave part 212. The abutting part 211 is used to abut against the flat part of the tire tread surface, and the concave part 212 is used to avoid the uneven parts of the tire. By setting at least two abutting parts 211 to abut against different flat parts of the tire tread surface, and then using the concave part 212 between the two abutting parts 211 to avoid the uneven parts, it is ensured that the tire tread plate 21 is in close contact with the tire tread surface, reducing the possibility of the tire tread detection device tilting.

[0065] By adopting the above technical solution, it is ensured that the tire plate 21 is in close contact with the tire tread surface, reducing the possibility of the tread detection device tilting, thereby reducing detection errors.

[0066] In one embodiment, the tire plate 21 further includes a magnetic part 213, which is disposed on the abutment part 211 and is used to cooperate with the calibration device.

[0067] It is understandable that the tire tread detection device needs to be calibrated by a calibration device before detection. The tire plate 21 is provided with a magnetic part 213 that cooperates with the calibration device. That is, the magnetic part 213 can fix the tire plate 21 on the calibration device, which facilitates the calibration operation.

[0068] Specifically, the tire tread detection device in this embodiment includes a calibration device such as a standard calibration block (not shown in the figure). The standard calibration block can be made of iron or stainless steel. The magnetic part 213 on the tire plate 21 is used to attach the tire tread detection device to the standard calibration block. The groove depth of the standard calibration block is measured as a standard depth for detection. Then, after the standard calibration block is removed, the actual depth of the tire tread is measured. The calibration is completed by analyzing the difference between the actual depth and the standard depth.

[0069] By adopting the above technical solution, the fixed connection structure between the tire plate 21 and the calibration device is simple and easy to operate.

[0070] In one embodiment, the positioning component 2 further includes a push rod 22, which is disposed on the detection housing 11 and extends away from the detection housing 11 along the length direction of the detection housing 11, and is disposed on the end of the push rod 22 away from the detection housing 11 near the tire plate 21.

[0071] Here, the push rod 22 is used to increase the extension length of the tire plate 21 relative to the detection housing 11. At the same time, the push rod 22 can prevent the large detection housing 11 from blocking the tire plate 21, so that the inspector can easily observe whether the tire plate 21 is in contact with the tire tread surface, thus improving the inspection efficiency.

[0072] By adopting the above technical solution, the tire plate 21 is easier to observe, thus improving the detection efficiency.

[0073] In one embodiment, the positioning assembly 2 further includes a push rod connector 23, which enables the push rod 22 to be detachably connected to the detection housing 11.

[0074] Here, the push rod connector 23 can be a tightening nut, which can tighten the push rod 22 onto the detection housing 11, so that the push rod 22 and the detection housing 11 can be detachably connected.

[0075] By adopting the above technical solution, it is easy to replace the top rod 22 and the tire plate 21. By changing the length of the top rod 22 and the tire plate 21 of different specifications, the applicability of the tire tread detection device can be improved.

[0076] In one embodiment, the detection element 31 includes a laser element 311 and an imaging element 312. The laser element 311 is used to emit a detection laser to form a detection light strip on the surface of the tire tread, and the imaging element 312 is used to acquire the detection light strip formed on the surface of the tire tread.

[0077] Here, the laser component 311 emits light in a direction parallel to the length of the detection housing 11, so that the detection light strip can be projected onto the tire tread surface in a set direction, and the camera component 312 can obtain a suitable detection light strip for analysis.

[0078] Furthermore, the detection housing 11 is provided with a laser element lens 313 corresponding to the laser element 311, and a camera element lens 314 corresponding to the camera element 312. The laser element lens 313 and the camera element lens 314 are respectively used to adjust the laser emission direction and to adjust the shooting range of the camera element 312.

[0079] By adopting the above technical solution, the detection accuracy of the detection element 31 is high.

[0080] In one embodiment, the detection component 3 further includes a control board 32 electrically connected to the laser element 311 and the camera element 312. The control board 32 is disposed inside the handle housing 12 and is used to control the laser element 311 and analyze the detection light strip acquired by the camera element 312.

[0081] Here, the control board 32 is located inside the handle housing 12 and is electrically connected to the laser component 311 and the camera component 312 via wires. This reduces the number of electronic components in the detection housing 11, shrinks the size of the detection housing 11, and makes it easier for the detection housing 11 to be inserted into the gap between the car bumper and the tire.

[0082] By adopting the above technical solution, the volume of the detection housing 11 is reduced, making it easier for the detection housing 11 to be inserted into the gap between the car bumper and the tire.

[0083] In one embodiment, the detection component 3 further includes a display panel 33 and a battery 34 electrically connected to the control panel 32. The display panel 33 is disposed on the surface of the handle housing 12, and the battery 34 is housed inside the handle housing 12.

[0084] Preferably, the display panel 33 is used to display detection information, and the display panel 33 is disposed on the surface of the handle housing 12 opposite to the detection housing 11, so that the detection personnel can more easily obtain the detection information; in addition, the battery 34 is housed inside the handle housing 12, which further reduces the volume of the detection housing 11, so that the detection housing 11 can adapt to smaller gaps in the car.

[0085] By adopting the above technical solution, the tire tread detection device becomes more suitable for use.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
