[0020] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0021] The rear wheel mounting auxiliary tool according to an embodiment of the present application will be described below in combination with Figure 1

[0022] ​The rear wheel mounting auxiliary tool provided by the embodiment of the utility model includes a profiling main body 1 and a laser device. The profiling main body 1 is provided with a positioning groove, the inner surface of the positioning groove is matched with the outer surface of the rear wheel, and the profiling main body 1 is adapted to be sleeved on the rear wheel through the positioning groove. The laser device is installed on the profiling main body 1, and the laser device can emit a laser beam used for calibration.

[0023] According to the rear wheel mounting auxiliary tool provided by the embodiment of the utility model, the inner surface of the positioning groove on the profiling main body 1 is matched with the outer surface of the rear wheel, so that the profiling main body 1 can be sleeved at the set position of the rear wheel through the positioning groove, and then the laser device connected with the profiling main body 1 is kept relatively fixed with the rear wheel, at this time, when the rear wheel is installed, as long as the calibration of the laser beam emitted by the laser device and the calibration area on the other components of the two-wheeled vehicle is completed, it means that the calibration of the rear wheel is completed, the coplanarity after the rear wheel is installed is high, and subsequent coplanarity detection and repair processing are not needed, the installation efficiency of the rear wheel is high, and the installation cost is low.

[0024] It should be noted that the calibration area on the other components of the two-wheeled vehicle includes but is not limited to a calibration point and a calibration line, for example, when the calibration area is a calibration point, the end of the laser beam emitted by the laser device coincides with the calibration point, and when the calibration area is a calibration line, the laser beam emitted by the laser device is located in the set direction of the calibration line and is parallel to the calibration line. For example, the calibration area is the center position of the front part of the frame, and the center position of the front stand pipe.

[0025] In some embodiments, the inner surface of the positioning groove includes an arc surface extending along the circumference of the rear wheel, and the arc surface is matched with the outer surface of the tire in the rear wheel.

[0026] That is, the profiling main body 1 is sleeved on the circumferential side of the rear wheel, and the arc surface abuts against the outer surface of the tire, so that the positioning reliability of the profiling main body 1 on the tire of the rear wheel is higher, and then when the rear wheel is installed, the profiling main body 1 is not easy to change the position relative to the rear wheel, and then the position calibration reliability of the rear wheel is higher.

[0027] Specifically, the arc surface is a smooth curved surface, that is, the arc surface is tangent to the outer surface of the tire, instead of being a concave-convex surface with a plurality of anti-skid grooves like the outer surface of the tire, and then the processing difficulty of the positioning groove is lower.

[0028] It should be noted that when the rear wheel is installed, the air pressure in the tire is a calibration air pressure, so that the shapes of the outer surfaces of the tires are equal, to ensure the calibration reliability of the rear wheel position by the rear wheel mounting auxiliary tool.

[0029] In some embodiments, the length of the arc surface in the circumference of the rear wheel is L1, and the length of the projection contour of the projection of the rear wheel on the projection plane perpendicular to the axial direction of the rear wheel is L2, and L1 is greater than or equal to 0.15*L2.

[0030] The setting guarantees that the arc surface has sufficient curvature in the circumferential direction of the tire, so that the positioning reliability of the profiling body 1 after being sleeved on the tire is higher, and the profiling body 1 and the tire are less likely to move.

[0031] Specifically, L2 refers to the outer diameter of the projection of the tire of the rear wheel in the axial direction, and the length L1 of the arc surface in the circumferential direction of the rear wheel can be 0.15 times, 0.2 times and 0.25 times of L2.

[0032] In some embodiments, the inner surface of the positioning groove further comprises two first side surfaces in abutment with the arc surface, the two first side surfaces are parallel to each other and are arranged at intervals along the axial direction of the rear wheel, and the distance between the two first side surfaces is equal to the maximum width of the tire of the rear wheel.

[0033] The setting guarantees that the arc surface has sufficient curvature in the circumferential direction of the tire, so that the positioning reliability of the profiling body 1 after being sleeved on the tire is higher, and the profiling body 1 and the tire are less likely to move.

[0034] In some embodiments, the first side surface extends along the circumferential direction of the rear wheel, and the width of the first side surface is d, where d≥1mm.

[0035] Thus, the first side surface is more stably abutted against the side edge of the tire, further reducing the probability that the profiling body 1 is not properly sleeved on the tire, and the profiling body 1 is less likely to be mismoved relative to the tire of the rear wheel when the rear wheel and the profiling body 1 are moved together.

[0036] Specifically, the first side surface extends along the circumferential direction of the rear wheel to the two edges of the arc surface, and the width of the first side surface refers to its size in the radial direction of the rear wheel, and at this time, d can be 1mm, 2mm and 3mm.

[0037] In some embodiments, the profiling body 1 extends along the circumferential direction of the rear wheel and is arranged in mirror symmetry relative to the first reference surface, the first reference surface is perpendicular to the axial direction of the rear wheel, and the center of gravity of the rear wheel coincides with the first reference surface. Thus, the symmetry of the profiling body 1 is better, and the manufacturing difficulty and cost are lower.

[0038] Specifically, the profiling body 1 can be an injection molded part, which extends along the axial direction of the wheel, and the thickness of any position thereof is equal.

[0039] In some embodiments, the center line of the laser beam emitted by the laser device coincides with the first reference surface.

[0040] That is, after the laser device is connected with the profiling body 1, as long as the laser beam emitted by the laser device can irradiate the center position of the front end of the frame, the coplanarity of the rear wheels can be ensured, and the alignment difficulty of the laser beam and the front end of the frame is lower, and the alignment reliability is higher.

[0041] In some embodiments, as shown in Figure 1 The rear wheel mounting auxiliary tool further includes a mounting seat 2 connected with the profiling body 1, and the laser device is detachably connected with the mounting seat 2.

[0042] That is, the laser device is mounted on the profiling body 1 through the mounting seat 2, and by setting the laser device to be detachably connected with the mounting seat 2, the maintenance and other operations of the laser device are facilitated, and the installation position of the laser device is also facilitated. Debugging.

[0043] Specifically, the mounting seat 2 is integrally formed with the profiling body 1, thereby further ensuring the positional reliability between the mounting seat 2 and the profiling body 1, and effectively avoiding the positional deflection of the mounting seat 2 relative to the profiling body 1 to affect the calibration accuracy of the laser device.

[0044] In some embodiments, a mounting groove 21 is provided on the side of the mounting seat 2 away from the profiling body 1, and the laser device is interference-fitted in the mounting groove 21.

[0045] The mounting groove 21 penetrates the mounting seat 2 along the extension direction thereof, and the laser device is interference-fitted in the mounting groove 21 from the opening on the side of the mounting seat 2 away from the profiling body 1. The mounting groove 21 realizes clamping positioning of the laser device, and ensures that the extension direction of the laser beam emitted by the laser device is consistent with the extension direction of the mounting groove 21.

[0046] Specifically, the shape of the bottom surface of the mounting groove 21 and the part of the side surface connected with the bottom surface matches the shape of the outer surface of the laser device, that is, the outer surface of the laser device is in contact, thereby further ensuring the installation position accuracy of the laser device on the mounting seat 2.

[0047] In some embodiments, the mounting seat 2 is mirror-symmetrically arranged relative to the first reference surface. At this time, the mounting groove 21 thereon is also mirror-symmetrically arranged relative to the first reference surface.

[0048] Thereby, the manufacturing difficulty and cost of the profiling body 1 and the mounting seat 2 are further reduced, and after the laser device is interference-fitted in the mounting groove 21, the center axis of the laser beam emitted by the laser device is better ensured to coincide with the first reference surface.
