[0030] In order to make those skilled in the art better understand the technical scheme of the present application, the following will describe the technical scheme in the embodiments of the present application clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0031] Please refer to Figures 1 to 6The embodiment provides a roller type wiper structure, and the scheme points of the roller type wiper structure include a framework 100, a roller 400 and a wiper structure 300. Figure 5 And Figure 6 As shown in the figure, when the wiper structure 300 is not in contact with the windshield, that is, the wiper structure 300 does not elastically deform, the bottom of the wiper structure 300 protrudes from the bottom of the roller 400, and the bottom refers to the side of the wiper structure 300 and the roller 400 that faces the surface of the windshield. In this way, when the wiper strip is installed on the vehicle wiper arm, the wiper structure 300 is first in contact with the windshield and elastically deformed, when the bottom of the roller 400 is in contact with the windshield, the bottom of the wiper structure 300 is elastically deformed and can be in contact with the surface of the windshield, at this time, the wiper structure 300 can extrude the surface of the windshield to perform the wiping action.

[0032] It can be seen that the roller type wiper structure can roll on the windshield and the bottom of the wiper structure 300 can simultaneously contact and extrude the windshield when the wiper strip is installed on the vehicle wiper arm, so that the wiper structure 300 can wipe off the water or other impurities on the windshield. The roller 400 supports the framework 100 and can prevent the pressure of the vehicle wiper arm on the windshield from being too large or the wiper strip from being too thick, so that the friction of the wiper strip on the windshield is not too large. The roller type wiper structure is more universal for different vehicles, the wiper structure 300 can apply constant pressure on the front windshield of the vehicle, so that the wiper strip can stably wipe off the water or other impurities on the windshield, the wiping effect can be effectively improved, the difficulty of the user in selecting the wiper strip is reduced, and the experience of the user is improved.

[0033] The roller type wiper structure in the embodiment can apply constant pressure to the front windshield of the automobile, so that the problem of the wiper structure 300 bouncing to a large extent and hitting the windshield at the start and stop positions of the work due to sudden turning is avoided. Specifically, when a common wiper strip is installed on the automobile wiper arm, the pressure applied by the rubber strip of the common wiper strip to the windshield is determined by the pressure applied by the automobile wiper arm to the wiper strip. Generally, the pressure applied by the automobile wiper arm to the wiper strip is the default maximum value, which causes the deformation of the rubber strip to be large, and the rubber strip bounces to a large extent at the start and stop positions of the work, which not only causes loud noise but also affects the wiping effect and service life of the wiper strip. The rubber strip of the roller type wiper structure proposed in the embodiment applies pressure to the windshield, which is determined by the diameter of the roller 400. By setting the roller 400 as a detachable structure, the user can accurately control the pressure applied by the rubber strip to the windshield, avoid the rubber strip bouncing to a large extent at the start and stop positions of the work due to large deformation, and make the roller type wiper structure have small working noise, good wiping effect, and long service life.

[0034] Further, please refer to Figures 1 to 3 The number of rollers 400 is two, and the two rollers 400 are rotatably installed at the two ends of the framework 100, and the diameters of the two rollers 400 are the same. The two rollers 400 can be installed by using the existing conventional rotary installation structure.

[0035] By installing the two rollers 400 at the two ends of the framework 100, and the diameters of the two rollers 400 being the same, the stability of the wiper strip on the windshield can be effectively improved, the shaking or deviation phenomenon caused by the inconsistent size of the rollers 400 is reduced, the contact between the wiper strip and the windshield is more uniform, the wiping effect can be effectively improved, the water stains, dirt, etc. on the windshield can be completely removed to improve the driving safety, and the friction noise between the wiper strip and the windshield during movement can be reduced to improve the driving comfort.

[0036] Optionally, the roller 400 is sleeved with an elastic material, so that the roller 400 will not break or scratch the windshield.

[0037] Preferably, please refer to Figures 2 to 6 The wiper structure 300 includes a rubber strip 310 and at least one wiping strip 320. The rubber strip 310 is connected to the framework 100 and extends along the length direction of the framework 100. The wiping strip 320 extends along the length direction of the rubber strip 310 and is arranged on the surface of the rubber strip 310 close to the windshield, so that the wiping strip 320 contacts the windshield.

[0038] Wherein, by setting multiple wiper strips 320 on the outer surface of the rubber strip 310 close to the windshield side, the roller-type wiper structure can be in contact with the windshield to different degrees when wiping water or other impurities on the windshield, and the contact area of the wiper strip 320 with the windshield is larger, and the contact surface is a sheet-shaped area, so that when the position of the wiper strip 320 in contact with the windshield is worn and has a gap, other parts of the wiper strip 320 in contact with the windshield can compensate for the gap position, and water or other impurities cannot pass through the wiper structure 300 through the worn gap, preventing water lines or other impurities from remaining on the windshield. By setting up in this way, the wiping effect can be improved, the service life of the product can be improved, the frequency of replacing the wiper strip by the user can be reduced, the cost of maintaining the wiper strip can be reduced, and the remaining water or other impurities on the windshield can be reduced.

[0039] Further, please refer to Figures 2 to 6 The rubber strip 310 is a hollow structure, and the center hole of the rubber strip 310 is arranged through along the length direction of the rubber strip 310.

[0040] Wherein, by setting the rubber strip 310 as a hollow structure, the hollow structure of the rubber strip 310 has better deformation ability, and the hollow structure of the rubber strip 310 can also reduce material cost and reduce the weight of the roller-type wiper structure. When the wiper arm of the car drives the skeleton 100 to swing back and forth, the wiper strip 320 is in contact with the windshield, and the wiper strip 320 is elastically deformed under the action of the wiper arm. The hollow structure of the rubber strip 310 provides a deformation space.

[0041] Optionally, please refer to Figures 1 to 6 The outer surface of the rubber strip 310 is curved, and the wiper strip 320 is arranged in multiple, and the multiple wiper strips 320 are arranged on the outer peripheral surface of the rubber strip 310 close to the windshield side in a circumferential direction.

[0042] Wherein, the outer surface of the rubber strip 310 is curved, which can better fit the curvature of the windshield, ensure that the wiper strip 320 is in close and uniform contact with the windshield, thereby improving the wiping effect, and also better adapt to the curved shape of the windshield of different vehicle models, ensure that the wiper strip 320 is in close contact with the windshield, and improve the wiping effect.

[0043] Preferably, the rubber strip 310 and / or the wiper strip 320 is made of rubber material.

[0044] The rubber material has good elasticity, can ensure that the wiper strip 320 is closely attached to the windshield, effectively removes water stains, dirt and other impurities, improves the wiping effect, the rubber material has high wear resistance, can maintain the wiping performance of the wiper strip 320 in long-term use, prolongs the service life of the wiper strip, and the rubber material has good damping performance, which can reduce the friction noise between the wiper strip and the windshield during wiping, and improve the driving comfort.

[0045] Optionally, please refer to Figures 1 to 4 The rubber strip 310 and the wiper strip 320 are integrally formed, and the skeleton 100 and the rubber strip 310 can also be integrally formed.

[0046] The rubber strip 310 and the wiper strip 320 are integrally formed, which can significantly enhance the overall strength of the wiper strip, avoid falling off or damage caused by loose connection between the rubber strip 310 and the wiper strip 320, and simplify the production process and reduce the production cost.

[0047] Further, please refer to Figures 1 to 3 The skeleton 100 is provided with a connecting structure 200 away from the windshield.

[0048] The connecting structure 200 is used to install the roller type wiper structure to the automobile wiper arm, and the connecting structure 200 is a buckle structure in the prior art. In other embodiments, other structures for connecting in the prior art can also be used. In addition, the mounting structure on the automobile wiper arm matched with the connecting structure 200 is also a prior art, which will not be described here.

[0049] Preferably, please refer to Figures 1 to 3 The skeleton 100 is provided with at least one reinforcing rib 110 extending outward, and the at least one reinforcing rib 110 extends along the length direction of the skeleton 100.

[0050] The reinforcing rib 110 can significantly enhance the rigidity of the skeleton 100, prevent the skeleton 100 from bending or deforming due to stress during wiping, ensure the overall structural stability of the wiper strip, reduce the vibration of the skeleton 100 during wiping, reduce the noise level, improve the driving comfort, reduce the maintenance requirement of the skeleton 100, reduce the maintenance cost, and prolong the maintenance cycle.
