[0022] In order to better understand the technical content of the utility model, specific embodiments are described and the accompanying drawings are described as follows.

[0023] Combined with Figure 1The utility model discloses a first aspect shows gutter wiper sleeve ring structure, gutter wiper sleeve ring structure sets up in gutter, the front of gutter connects the engine hood, and the rear connects the windshield, and the wiper is installed in the gutter, because the wiper is in rotation, relative displacement is generated to the gutter, therefore, requires that the wiper sleeve ring structure has certain flexibility, and also has wear resistance.

[0024] Combining Figure 2 The utility model discloses a first aspect shows gutter wiper sleeve ring structure, gutter wiper sleeve ring structure sets up in gutter, the front of gutter connects the engine hood, and the rear connects the windshield, and the wiper is installed in the gutter, because the wiper is in rotation, relative displacement is generated to the gutter, therefore, requires that the wiper sleeve ring structure has certain flexibility, and also has wear resistance.

[0025] Thus, the sleeve ring structure formed by two sleeve rings is arranged between the wiper shaft 40 and the groove body 10, wherein the hardness of the second sleeve ring 30 is greater than the hardness of the first sleeve ring 20, so that when the wiper shaft 40 rotates, the second sleeve ring 30 with greater hardness contacts the wiper 40 to achieve high wear resistance, and the first sleeve ring 20 deforms.

[0026] Further, the outer wall of the second sleeve ring 30 is provided with a first clamping structure, the inner ring area 23 of the first sleeve ring 20 is provided with a second clamping structure, and the first clamping structure and the second clamping structure are clamped and connected.

[0027] Because the second sleeve ring 30 also has a tendency to rotate relatively when the wiper shaft 40 rotates, the connection between the first sleeve ring 20 and the second sleeve ring 30 has a large rotational stress, and the clamping connection can withstand greater rotational stress, which is more reliable than the glue bonding method.

[0028] Further, the outer ring area 21 and the inner ring area 23 of the first sleeve ring 20 are provided with a deformation area 22, and the first sleeve ring 20 is easily deformed in the deformation area 22, so that the relative positions of the inner ring area 23 and the outer ring area 21 change.

[0029] Thus, when the inner ring area 23 of the first sleeve ring 20 is displaced relative to the outer ring area 21, the deformation area 22 can be deformed to reduce the stress on the outer ring area 21 caused by the displacement of the inner ring area 23.

[0030] In an optional embodiment, the deformation area 22 includes at least one pleat structure, the outer edge of the pleat structure is connected to the outer ring area 21, and the inner edge of the pleat structure is connected to the inner ring area 23.

[0031] Thus, the pleat structure is easily deformed and can adapt to a larger range of deformation, such as up and down and left and right floating and small angle rotation.

[0032] Combining Figure 2 And Figure 3 As shown in the drawings, the inner wall of the inner ring area 23 is provided with a clamping groove 24, and the clamping groove 24 is provided with a clamping hole extending in the thickness direction of the first ring 20.

[0033] Further, the second ring 30 includes an inner ring 31 and an outer ring 32, the outer ring 32 is located outside the inner ring 31, and the thickness of the outer ring 32 is less than the thickness of the inner ring 31, and the thickness of the outer ring 32 is the same as the thickness of the clamping groove 24.

[0034] As shown in the drawings, the outer wall of the outer ring 32 is provided with a protruding structure 33. Figure 3

[0035] Therefore, when the outer ring 32 extends into the clamping groove 24, the protruding structure 33 is clamped with the corresponding clamping hole, the outer ring 32 and the inner ring area 23 are fixed, the relative position between the two is stable, the two are connected by the clamping of the protruding structure 33 and the clamping hole, and the anti-torsion and anti-tension ability is strong, and the reliability is high.

[0036] Specifically, the inner hole 34 of the inner ring 31 slides relative to the wiper shaft 40, so that the wiper shaft 40 can freely rotate in the inner hole 34.

[0037] In an optional embodiment, the first ring 20 includes an ABS, PC or PP structure. The above structure has high hardness and can meet the high friction environment generated by the rotation of the wiper shaft 40 in the inner hole 34 and the relative sliding of the structure.

[0038] In an optional embodiment, the second ring 30 includes a silica gel, TPE or TPU structure. The above structure has low hardness and good elasticity, and can adapt to the deformation generated by the displacement change of the second ring 30.

[0039] In combination with the above embodiments, the wiper ring structure provided by the utility model includes a soft and a hard ring, the hard ring is connected to the outer wall of the wiper shaft, and the soft ring is connected to the groove body of the water falling groove. When the wiper shaft rotates, the hard ring meets the wear resistance requirement, and the soft ring can realize small amplitude deformation and adapt to the displacement caused by the rotation of the wiper shaft, thereby reducing the mutual stress between the hard structures.

[0040] Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Those skilled in the art can make various modifications and decorations without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the definition of the claims.​
