Description

Technical Field

[0001] The utility model relates to a protection technology for automobile wiper rubber strips, in particular to a protection cover for preventing the wiper rubber strips from being compressed and deformed. Background Art

[0002] Due to their rubber properties, automotive wiper strips can bend and deform under the pressure of the wiper arm when the vehicle is not in use, especially during long-term parking or transport. This can make it difficult to restore the ideal angle of attack (i.e., the angle between the normal to the windshield and the normal to the wiper strip at the wiper strip's contact point). Deformed wiper strips often cause blade vibration, unusual noise, and reduced cleanliness during wiping, impacting driving safety and driver satisfaction.

[0003] Obviously, the existing automobile wiper rubber strips have the problem of bending and deformation under the long-term pressure of the wiper arm, which leads to shaking, abnormal noise and reduced scraping efficiency during the wiping process. Summary of the Invention

[0004] In order to solve the problems of the existing automobile wiper strips that will bend and deform under the long-term pressure of the wiper arm, resulting in shaking, abnormal noise and reduced scraping efficiency during the wiping process, the utility model proposes a protective cover to prevent the wiper strips from being compressed and deformed.

[0005] The utility model discloses a protective cover for preventing the wiper rubber strip from being compressed and deformed, comprising a protective cover and a flexible pad; the protective cover as a whole is an arc-shaped structure and the curvature of the curvature is the same as that of the automobile wiper arm, comprising a cover body and a buckle; the cross-sectional shape of the cover body is V-shaped, and a pressure-bearing step is provided on the left side of the V-shaped opening of the cover body; the buckles are spaced apart on both sides of the V-shaped opening of the cover body, comprising a left buckle and a right buckle; the left buckle and the right buckle are both flexible curved strips, and hanging teeth are provided at the heads of the left buckle and the right buckle relative to each other; the flexible pad is a long rubber strip with a rectangular cross-section, which is fixed to the bottom of the cover body.

[0006] Furthermore, the bending portions of the left buckle and the right buckle are both provided with a retreat groove with a circular cross-section.

[0007] Furthermore, a wrench is provided on the head of the right buckle extending outward.

[0008] Furthermore, the protective cover is a PVC or PP injection molding structure.

[0009] Furthermore, the flexible pad is fixed to the bottom of the cover body, including that the flexible pad is adhered to the bottom of the cover body, or that the cover body and the flexible pad are a two-color injection molding structure.

[0010] The beneficial technical effect of the protective cover of the utility model for preventing the wiper strip from being compressed and deformed is that the wiper strip can be placed in the protective cover when it is parked for a long time or transported to another site, preventing it from bending and deforming due to pressure, and avoiding problems such as shaking, abnormal noise and reduced scraping efficiency during wiping of the wiper.

[0017] The protective cover for preventing the wiper strip from being compressed and deformed according to the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. DETAILED DESCRIPTION

[0018] Referring to the accompanying drawings, the utility model discloses a protective cover for preventing the wiper rubber strip from being compressed and deformed, comprising a protective cover 1 and a flexible pad 2; the protective cover as a whole is an arc-shaped structure and the curvature is the same as that of the automobile wiper arm, comprising a cover body 1-1 and a buckle; the cross-sectional shape of the cover body is V-shaped, and a pressure-bearing step is provided on the left side of the V-shaped opening of the cover body; the buckles are spaced apart on both sides of the V-shaped opening of the cover body; comprising a left buckle 1-2 and a right buckle 1-3; the left buckle and the right buckle are both flexible curved strips, and hanging teeth are provided at the heads of the left buckle and the right buckle relative to each other; the flexible pad is a long rubber strip with a rectangular cross-section, which is fixed to the bottom of the cover body. To use the protective cover, pull the car wiper to an upright position, align the V-shaped opening of the protective cover with the wiper rubber strip, and move it toward the side of the wiper until the car wiper is fully inserted into the V-shaped opening of the protective cover. Then, pull the left and right buckles one by one so that the teeth on the buckle heads engage with each other. The car wiper and the protective cover are then placed back on the car windshield, completing the installation of the protective cover. Because the car wiper is placed within the V-shaped opening of the protective cover, and a pressure-bearing step is provided on the left side of the V-shaped opening of the protective cover, the pressure on the wiper arm is borne by the pressure-bearing step, which does not put pressure on the wiper rubber strip and cause it to bend or deform. Because the bottom of the protective cover is provided with a flexible pad, the car wiper can be directly opened to wipe the windshield when scraping is needed temporarily. When the car wiper needs to be used frequently, the left and right buckles can be opened, the protective cover can be removed from the car wiper, and the car wiper can be placed back on the car windshield for normal use.

[0019] As one of the preferred technical solutions, the bending portions of the left and right buckles are each provided with circular cross-sectional relief grooves 1-4. The provision of relief grooves can make bending of the left and right buckles easier, shifting the bending deformation of the left and right buckles from material deformation to primarily shape deformation, thereby preventing fatigue damage to the left and right buckles.

[0020] Furthermore, a wrench 1-5 is provided extending outward from the head of the right buckle.

[0021] Furthermore, the protective cover is a PVC or PP injection molding structure.

[0022] As one of the preferred technical solutions, the head of the right buckle is extended outwardly and provided with a wrench 1-5. The provision of the wrench can make it possible to have a force point to assist the right buckle to move toward the left buckle for fastening or exiting when opening or closing the left and right buckles, making the overall design more practical and user-friendly.

[0023] As one of the preferred technical solutions, the shield is a PVC or PP injection molding structure. Using PVC or PP injection molding to make the shield can reduce production expenses and reduce production costs.

[0024] As a preferred technical solution, the flexible pad is fixed to the bottom of the cover body, including adhesive bonding, or the cover body and the flexible pad are two-color injection molded. Adhesive bonding offers advantages such as simplicity and low cost, while two-color injection molding offers a more aesthetically pleasing and secure fixation. The choice can be made based on your needs.

[0025] Obviously, the beneficial technical effect of the protective cover of the utility model that prevents the wiper strips from being compressed and deformed is that the wiper strips can be placed in the protective cover during long-term parking or transfer transportation to prevent bending and deformation caused by pressure, and avoid problems such as shaking, abnormal noise and reduced scraping efficiency during wiping.
