[0043] Embodiment:

[0044] As Figures 1 to 14 shown:

[0045] An anti-splash system auxiliary measuring device, which includes a clamping part 1, an auxiliary rod 2, and a rotating part 3;

[0046] The rotating part 3 is arranged on the back side of the clamping part 1. The rotating plane of the rotating part 3 is parallel to the plane where the clamping part 1 is located. A fixing hole 33 is arranged on the rotating part 3, and the axis of the fixing hole 33 is parallel to the rotating plane of the rotating part 3;

[0047] The auxiliary rod 2 includes a fixing rod 21 and a bent rod 22. The fixing rod 21 is inserted into the fixing hole 33, and the bent rod 22 is hinged to the end of the fixing rod 21.

[0048] When using this anti-splash system auxiliary measuring device, the staff can fix the clamping part 1 on the inner ring of the wheel spoke or on the hub. Then, a reference line can be established through the auxiliary rod 2 to more easily measure the relevant parameters of the anti-splash system required; the specific measurement method is as follows:

[0049] When measuring the position of the outer baffle, it is necessary to measure the distance a between the longitudinal plane tangent to the outer tire wall and the inner edge of the outer baffle except for the tire protrusions in contact with the ground. The staff can adjust the auxiliary rod 2, adjust the bent rod 22 to a straight state so that it coincides with the plane where the outer tire wall is located, or after bending, make it coincide with the plane where the outer tire wall is located. Then, extend the end of the bent rod 22 away from the clamping part 1 to the same height as the inner edge of the outer baffle. At this time, the staff can easily measure the distance a between the longitudinal plane tangent to the outer tire wall and the inner edge of the outer baffle by using a measuring tool (as Figure 9 and Figure 10 shown);

[0050] When measuring the radial distance b from the lower edge of the outer baffle to the wheel center, the staff can first observe the position of the farthest point from the wheel center to the lower edge of the outer baffle, and then adjust the position of the auxiliary rod 2 through the rotating part 3 so that the end of the auxiliary rod 2 away from the clamping part 1 directly points to the position of the farthest point from the wheel center to the lower edge of the outer baffle. At this time, the staff can directly measure the length of the auxiliary rod 2 corresponding to the farthest point from the wheel center to the lower edge of the outer baffle with a measuring tool to complete the measurement of the radial distance b from the lower edge of the outer baffle to the wheel center (as Figure 11 shown);

[0051] When measuring the distance c between the rear edge of the baffle and the horizontal line passing through the wheel center, the staff can rotate the rotating part 3 until the rotating part 3 is in a horizontal state, so that the auxiliary rod 2 is parallel to the horizontal plane, and then extend the end of the auxiliary rod 2 to the side of the rear edge of the baffle so that the end of the auxiliary rod 2 is located below the rear edge of the baffle. At this time, the staff can directly measure the distance between the end of the auxiliary rod 2 and the rear edge of the baffle, that is, the distance c between the rear edge of the baffle and the horizontal line passing through the wheel center (as Figure 12 shown);

[0052] When measuring the distance d between the rain curtain and the last edge of the wheel, the staff can rotate the rotating part 3 until the rotating part 3 is in a horizontal state, so that the auxiliary rod 2 is parallel to the horizontal plane, and then extend the end of the auxiliary rod 2 to the last edge of the wheel, and then bend the bending rod 22 of the auxiliary rod 2 so that the end of the bending rod 22 away from the fixed rod 21 closely adheres to the crown of the tire. At this time, the staff can directly measure the distance d between the bending position of the bending rod 22 and the rain curtain (as Figure 13 shown);

[0053] When measuring the angle α between the radial line from the wheel center to the front edge of the mudguard and the horizontal line, the staff can rotate the rotating part 3 until the rotating part 3 is in a horizontal state, then place the inclinometer on the rotating part 3, and then rotate the rotating part 3 and make the inclinometer rotate with the rotating part 3 until the end of the auxiliary rod 2 away from the clamping part 1 coincides with the front edge of the mudguard. At this time, the staff can directly read the angle shown by the inclinometer, and this angle is the angle between the auxiliary rod 2 and the horizontal line, that is, the angle α between the radial line from the wheel center to the front edge of the mudguard and the horizontal line (as Figure 14 shown).

[0054] Optimally, a level 34 is provided on the above-mentioned rotating part 3. The setting of this level 34 can facilitate the staff to calibrate the rotating part 3 to judge whether the rotating part is in a horizontal state, so that the use of the anti-splash system auxiliary measuring device is more convenient.

[0056] Preferably, a marking line 222 is provided at the hinged end of the above-mentioned connecting rod 221. The length direction of the marking line 222 is parallel to the length direction of the connecting rod 221. The plurality of connecting rods 221 are arranged in a straight line by comparing the marking lines 222, so that the data measured by the anti-splash system auxiliary measuring device is more accurate.

[0057] Preferably, a limiting device is provided at the hinged end of the above-mentioned connecting rod 221. The limiting device can prevent the connecting rod 221 from rotating away from the wheel around the rotation center of its hinged end, so as to make the use of the anti-splash system auxiliary measuring device more convenient.

[0058] Optimized, the anti-splash system auxiliary measuring device further includes a connecting portion 4. The connecting portion 4 can increase the distance between the clamping portion 1 and the rotating portion 3, so that the anti-splash system auxiliary measuring device can be adapted to the measurement of more vehicle models; and both ends of the connecting portion 4 are detachably connected to the clamping portion 1 and the rotating portion 3 respectively, so that the disassembly / assembly and storage of the anti-splash system auxiliary measuring device are more convenient.

[0059] Specifically, the above-mentioned connecting portion 4 includes an adjusting nut 41 and an adjusting screw 42; wherein,

[0060] The fixed end of the adjusting nut 41 is arranged at the center of the clamping portion 1. An installation hole A411 is provided at the end of the adjusting nut 41 away from the clamping portion 1, and an internal thread is provided in the installation hole A411; the fixed end of the adjusting screw 42 is arranged at the center of the rotating portion 3. An installation portion A421 is provided at the end of the adjusting screw 42 away from the rotating portion 3, and an external thread is provided on the installation portion A421. The adjusting nut 41 and the adjusting screw 42 are detachably connected through the cooperation of the installation hole A411 and the installation portion A421;

[0061] And during use, the user can adjust the distance between the clamping portion 1 and the rotating portion 3 by rotating the installation portion A421, so as to make the use of the anti-splash system auxiliary measuring device more convenient.

[0062] Optimized, an installation portion B is provided at the fixed end of the above-mentioned adjusting nut 41. An external thread is provided on the outer side wall of the installation portion B. An installation hole B is provided at the center of the clamping portion 1, and an internal thread is provided on the inner side wall of the installation hole B. The adjusting nut 41 and the clamping portion 1 are detachably connected through the cooperation of the installation portion B and the installation hole B, so as to make the disassembly and assembly of the adjusting nut 41 and the clamping portion 1 more convenient.

[0063] Optimized, the fixed end of the above-mentioned adjusting screw 42 is provided with a mounting hole C, and an internal thread is provided in the mounting hole C. An installation part C is provided at the center of the rotating part 3, and an external thread is provided on the outer side wall of the installation part C. The adjusting screw 42 and the rotating part 3 are detachably connected through the cooperation of the mounting hole C and the installation part C, so that the disassembly and assembly of the adjusting screw 42 and the rotating part 3 are more convenient.

[0064] Optimized, the above-mentioned rotating part 3 includes a connecting disk 31 and a rotating body 32; among them,

[0065] A rotating bearing is provided on the connecting disk 31, the rotation center of the rotating bearing coincides with the center of the connecting disk 31, and the rotating body 32 is rotatably arranged on the connecting disk 31 through the rotating bearing. The above-mentioned fixing hole 33 is provided on the rotating body 32;

[0066] The above-mentioned auxiliary rod 2 is inserted on the rotating body 32, so that the auxiliary rod 2 can rotate together with the rotating body 32, so as to facilitate adjusting the position where the auxiliary rod 2 is located.

[0067] Optimized, the shapes of the above-mentioned fixing hole 33 and the cross-section of the fixing rod 21 are both circular, and a limiting post is provided on the inner side wall of the fixing hole 33, and a limiting groove 211 matching the limiting post is provided on the circumferential outer side wall of the fixing rod 21;

[0068] When the fixing rod 21 is inserted into the fixing hole 33, the limiting groove 211 on the fixing rod 21 just engages with the limiting post in the fixing hole 33 to prevent the fixing rod 21 from rotating in the fixing hole 33.

[0069] Optimized, the above-mentioned clamping part 1 includes a fixing part 11, clamping claws 12 and a driving device; among them,

[0070] The fixing part 11 is a circular disk-shaped structure. The number of the clamping claws 12 is three. The three clamping claws 12 are all movably arranged on the fixing part 11 through the driving device, and the three clamping claws 12 are arranged equidistantly around the center of the fixing part 11. The clamping claws 12 all extend and retract along the radial direction of the fixing part 11, so that the clamping part 1 can firmly clamp on the inner ring of the spoke or the hub of the vehicle to be detected, so as to prevent the auxiliary measuring device of the anti-splash system from falling during use.

[0071] It should be noted that the number of the above-mentioned clamping claws 12 is not limited to three, and it can also be set to four, five or more, that is, as long as the clamping part 1 can firmly clamp on the inner ring of the spoke or the hub of the vehicle to be detected.

The axis of the extension hole B122 is parallel to the plane where the fixing part 11 is located. The extension claw 14 is detachably arranged at the extension hole B122;

[0073] When using the anti-splash system-assisted measuring device, when the clamping claw 12 cannot fix the clamping part 1 on the wheel due to the insufficient length of the clamping end, the staff can install the extension post 13 on the clamping claw 12 to increase the length of the clamping claw 12 so that it can be firmly clamped on the inner circle of the spoke or the hub;

[0074] When the clamping claw 12 cannot fix the clamping part 1 on the wheel due to the small expansion size of the clamping end, the staff can install the extension claw 14 on the clamping claw 12 to increase the expansion size of the clamping claw 12 so that it can be firmly clamped on the wheel, thereby making the use of the anti-splash system-assisted measuring device more convenient.

[0075] Optimized, a laser module 15 is arranged at the center of the circle of the above-mentioned fixing part 11. The laser module 15 can emit laser light to facilitate detecting whether the center line of the clamping part 1 is aligned with the center of the wheel, thereby further improving the accuracy of the anti-splash system-assisted measuring device.

[0076] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
