[0031] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

They are only for the convenience of description and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this patent. The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0033] In order to illustrate the technical solution described in this application, the following is a detailed description with reference to specific drawings and embodiments.

[0034] See also Figure 1 and Figure 2As shown, the embodiment of the present application first provides a wheel clamping mechanism 100, which is used to clamp on each wheel of the vehicle to be inspected and remain relatively fixed with the wheel to reflect the position and / or movement of the wheel.

[0035] The wheel clamping structure can be used in vehicle detection and calibration processes including but not limited to ADAS (Advanced Driver Assistance Systems) calibration, four-wheel alignment calibration, etc.

[0036] Specific as Figure 1 and Figure 2 As shown, the wheel clamping mechanism 100 includes a clamping body 5 and a plurality of clamping members 6 fixedly connected to the clamping body 5. The clamping members 6 are configured to directly contact the wheel of the vehicle to be inspected. The connection between the clamping members 6, via the clamping body 5, generates a force that secures the wheel. In one embodiment, the clamping body 5 can also be used to adjust the position, angle, and distance between the clamping members 6 to accommodate various wheel sizes.

[0037] The specific structure of the clamping body 5 is not limited, and the adjustment method of each clamping member 6 is not limited.

[0038] For example Figure 1 and Figure 2 As shown, in one embodiment, the clamping body includes a base 51, a screw 52, and two supports 53. The screw 52 is mounted on the base 51 and can rotate about its own central axis. The screw 52 includes two threaded sections with opposite rotation directions. The two supports 53 are respectively engaged with one threaded section and are slidably mounted on the base 51. Each support 53 is provided with at least one clamping member 6. When the screw 52 is rotated, the screw 52 pushes the two supports 53 to move toward or away from each other, thereby causing the clamping members 6 to move toward or away from each other. Consequently, the clamping members 6 can clamp and release the wheel.

[0039] The two supports 53 are generally arranged in a mirror-symmetrical manner. In one embodiment, each support 53 is provided with more than one clamping member 6. In this way, the wheel clamping mechanism 100 can clamp the wheel more stably and balancedly.

[0040] See also Figure 1 and Figure 2 As shown, in a specific embodiment, two clamping members 6 are provided on each support 53, and the wheel clamping mechanism 100 includes a total of four clamping members 6. The four clamping members 6 perform four-point clamping on the wheel, which is conducive to ensuring stable and balanced clamping.

[0041] In one embodiment, the clamping member 6 is detachably connected to the support 53. In this way, the clamping member 6 can be disassembled or replaced when necessary.

[0042] Also, see Figure 2 As shown, each support 53 is provided with a connection point 530 for connecting to a clamping member 6, with one end of the clamping member 6 mounted on the connection point 530. Optionally, the support 53 may be provided with two groups of connection points 530. Multiple connection points 530 in one group have the same distance from the center of the screw 52, while connection points 530 in different groups have different distances from the center of the screw 52. In other words, the clamping member 6 can be mounted on one of the groups of connection points 530 as needed, allowing the multiple clamping members 6 to better adapt to wheels of different diameters.

[0043] In one embodiment, the wheel clamping mechanism 100 further includes a calibration member (not shown). The calibration member is fixed to the clamping body 5 and serves as a reference mark for detection by a calibration detection device associated with the wheel clamping mechanism 100, or as a sensor device for data communication with the calibration detection device. The specific type of the calibration member is related to the specific function of the calibration detection device and is not particularly limited herein.

[0044] The clamping member 6 is used to be in direct contact with the wheel, so the clamping member 6 directly applies pressure to the wheel.

[0045] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the clamping member 6 provided in the embodiment of the present application includes a clamping claw 61 and an anti-scratch member 65. One end of the clamping claw 61 is used to be fixedly connected to the clamping body 5, and the other end of the clamping claw 61 is used to be connected to the wheel.

[0046] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, each clamping jaw 61 includes a connecting section 611 and a clamping section 613 , wherein the connecting section 611 is fixedly connected to the clamping body 5 , and the clamping section 613 is used to contact the wheel.

[0047] The connecting section 611 and the clamping section 613 may be integrally connected, that is, the two are integrally manufactured.

[0048] The specific structure of the connecting section 611 is related to the specific structure of the connecting position 530 and is not particularly limited in the embodiment of the present application, as long as the two can form a stable connection.

[0049] Please continue reading Figure 3 、 Figure 4 、 Figure 5and Figure 6 As shown, in one embodiment, an anti-slip structure 612 is provided on the outer surface of the portion of the connecting section 611 near the clamping section 613. The anti-slip structure 612 facilitates the connection of the connecting section 611 to the support 53. For example, the worker can hold the anti-slip structure 612 by hand or with a tool and then install the connecting section 611 on the connecting position 530.

[0050] The anti-slip structure 612 can be formed in any form. For example, the anti-slip structure 612 can be a rough surface integrally formed on the surface of the connecting section 611; or the anti-slip structure 612 can include an anti-slip sleeve, such as a rubber sleeve or silicone sleeve, which is applied to the connecting section 611. Further anti-slip implementations are not described in detail.

[0051] See also Figure 4 and Figure 6 As shown, the end of the clamping jaw 61 facing the wheel, that is, the end of the clamping section 613 facing away from the connecting section 611, has a first surface 6131 and a second surface 6132, the first surface 6131 is used to abut the outer peripheral surface of the wheel hub, and the second surface 6132 is configured to face the outer surface of the wheel hub.

[0052] During use, the first surfaces 6131 of the multiple clamping jaws 61 contact multiple points on the outer circumference of the hub to apply a generally radially inward force to the hub, thereby achieving multi-point clamping of the hub and a fixed connection between the clamping member 6 and the hub. The second surface 6132 is arranged to face the outer surface of the hub and is used to locate the axial position between the clamping member 6 and the hub.

[0053] At least a portion of the anti-scratch member 65 is positioned on the second surface 6132 and abuts the outer surface of the wheel hub. Specifically, the anti-scratch member 65 is clamped between the second surface 6132 and the outer surface of the wheel hub. The anti-scratch member 65 prevents the second surface 6132 of the clamping jaw 61 from scratching the outer surface of the wheel hub, thereby maintaining the appearance of the customer's wheel hub. The outer peripheral surface of the wheel hub refers to the outer axial end surface of the wheel hub.

[0054] It will be appreciated that the anti-scratch member 65 is made of a non-flexible material, meaning that it is not compressed when clamped between the second surface 6132 and the outer surface of the hub. This ensures that the distance between the second surface 6132 of each clamping jaw 61 and the outer surface of the hub is equal. In other words, each clamping jaw 61 is clamped at the same position on the hub, and the multiple clamping jaws 61 are symmetrically distributed around the central axis of the hub. This ensures that the aforementioned calibration element remains in its predetermined position relative to the hub, preventing positional shifts due to the displacement of a single clamping jaw 61, thereby ensuring the accuracy of the calibration test.

[0055] Furthermore, the hardness of the material of the anti-scratch member 65 is less than the hardness of the material of the wheel hub. Typically, the material of the wheel hub is a metal material, such as steel or aluminum alloy.

[0056] In one embodiment, the scratch-proof member 65 is made of a hard plastic material such as polyoxymethylene, polyamide, polycarbonate, or polyphenylene sulfide. Optionally, the scratch-proof member 65 is integrally formed, specifically, by injection molding. Injection molding of the scratch-proof member 65 provides greater dimensional consistency and is easier to manufacture to match the shape of the second surface 6132.

[0057] The material of the clamping jaws 61 is preferably selected to ensure strength and avoid deformation when multiple clamping jaws 61 interact with each other.

[0058] In one embodiment, the clamping jaw 61 is a metal part, specifically a steel part or an aluminum alloy part. Other materials with sufficient strength are also allowed to be used, and no further examples are given here.

[0059] Since the first surface 6131 and the second surface 6132 of the clamping jaw 61 abut against different surfaces of the wheel hub, the first surface 6131 and the second surface 6132 are not located in the same plane. Figure 4 and Figure 6 As shown, a recessed portion 6130 is provided at one end of the clamping jaw 61 away from the clamping body 5 , and side surfaces of the recessed portion 6130 serve as a first surface 6131 and a second surface 6132 , respectively.

[0060] The first surface 6131 is generally an arc-shaped surface to match the arc-shaped outer peripheral surface of the hub. The second surface 6132 is designed to match the outer surface of the hub. For example, the second surface 6132 can be generally flat, or in other embodiments, can be curved.

[0061] Next, see Figure 3 and Figure 4 As shown, a scratch-proof member 65 of a structure is provided.

[0062] The anti-scratch member 65 includes an anti-scratch sheet 651, which is mounted on the second surface 6132. Part of the outer circumference of the anti-scratch sheet 651 can abut against part of the first surface 6131. At this time, the shape of the anti-scratch sheet 651 is designed according to the shape of the second surface 6132.

[0063] In an optional embodiment, the anti-scratch sheet 651 is bonded to the second surface 6132 via an adhesive. Since the anti-scratch sheet 651 and the wheel hub generally generate forces in a direction substantially perpendicular to the second surface 6132, and less forces are generated along the second surface 6132, the adhesive bonding between the anti-scratch sheet 651 and the second surface 6132 can also ensure a stable connection, and the anti-scratch sheet 651 will not easily fall off.

[0064] In an optional embodiment, a groove (not shown) is provided on the second surface 6132, and a portion of the anti-scratch sheet 651 is disposed in the groove. The groove accommodates and limits the anti-scratch sheet 651, which can further improve the connection stability between the anti-scratch sheet 651 and the second surface 6132.

[0065] Optionally, in this embodiment, the inner bottom wall and / or the inner peripheral wall of the groove may be bonded to the anti-scratch sheet 651 by an adhesive.

[0066] The inner dimensions of the groove can be set slightly smaller than the outer dimensions of the anti-scratch sheet 651, so that the anti-scratch sheet 651 and the groove form a fixed connection in the form of an interference fit. Furthermore, optionally, the inner bottom wall and / or inner peripheral wall of the groove can also be provided with an adhesive. In this way, the anti-scratch sheet 651 and the groove are combined in various ways, further improving their installation stability.

[0067] Next, see Figure 5 and Figure 6 As shown, another structure of the scratch-proof member 65 is provided.

[0068] In this embodiment, the anti-scratch member 65 includes an anti-scratch cover 652. The anti-scratch cover 652 is mounted on the end of the clamping jaw 61 away from the clamping body 5, that is, the end of the clamping section 613 facing away from the connecting section 611, and covers both the first surface 6131 and the second surface 6132. Of course, the anti-scratch cover 652 also covers the outer circumference of the end of the clamping section 613 facing away from the connecting section 611. In this case, the shape of the anti-scratch cover 652 matches the shape of the end of the clamping section 613 facing away from the connecting section 611.

[0069] In one embodiment, an adhesive is provided between the inner wall surface of the anti-scratch cover 652 and at least a portion of the outer peripheral surface of the end of the clamping section 613 facing away from the connecting section 611 , and the anti-scratch cover 652 is bonded to the end of the clamping section 613 facing away from the connecting section 611 .

[0070] In one embodiment, the inner dimension of the anti-scratch cover 652 is designed to be slightly smaller than the outer dimension of the end of the clamping section 613 facing away from the connecting section 611. At this time, the anti-scratch cover 652 and the end of the clamping section 613 facing away from the connecting section 611 are connected by an interference fit.

[0071] In one embodiment, the anti-scratch cover 652 and the end of the clamping section 613 facing away from the connecting section 611 can be fixedly connected by both bonding and interference fit. For example, the outer circumference of the end of the clamping section 613 facing away from the connecting section 611 can be interference fit with a portion of the inner circumference of the anti-scratch cover 652, while the first surface 6131 and / or the second surface 6132 can be bonded to the corresponding inner circumference of the anti-scratch cover 652 using an adhesive.

[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
