Description

Technical Field

[0001] This utility model belongs to the field of automotive wiper technology, and in particular relates to an automotive wiper rubber strip. Background Technology

[0002] Car windshield wipers (also called windshield wipers) are devices used on cars to remove rainwater, snow, mud, sand, and other debris from the windshield, ensuring the driver has a clear view while driving. They consist of a wiper arm and a wiper blade (rubber strip). They work by using an electric motor to drive the wiper arm to swing left and right, causing the wiper blade to scrape the windshield.

[0003] Currently, the connection between the wiper arm and the wiper blade is usually achieved by mounting the wiper blade on a fixed steel strip, and then using clips to clamp the fixed steel strip to ensure a firm connection between the fixed steel strip and the wiper blade. The wiper arm is connected to the clips to move the fixed steel strip, so that the wiper blade can wipe on the windshield.

[0004] While the above connection method can ensure that the wiper blade is securely installed on the wiper arm, when the wiper blade becomes worn at the end due to frequent use and can no longer effectively wipe the windshield, the entire wiper blade needs to be removed from the fixing steel strip, which is troublesome, time-consuming and laborious. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing an automotive wiper blade that solves those problems.

[0006] In view of this, the present invention provides an automotive wiper blade rubber strip, comprising:

[0007] The fixing part has connecting grooves arranged in the X direction on both sides along the Y direction, and a mounting groove arranged in the X direction on one side along the Z direction.

[0008] The wiper unit has a connecting strip installed along the X direction, and the connecting strip is fitted and snapped into the mounting groove.

[0009] A baffle plate is rotatably mounted on a fixed part and is fitted into a mounting groove.

[0010] Furthermore, an arc-shaped clip is provided on the side of the fixing part that has a mounting groove along the Z direction, and the arc-shaped clip abuts against the wiper part along the Y direction.

[0011] Furthermore, the wiper unit has concave arc surfaces on both sides along the Y direction.

[0012] Furthermore, the end of the wiper unit along the Z-direction has a rounded structure.

[0013] Furthermore, there are several mounting slots and wiper units, and each wiper unit is adapted to and connected to each mounting slot via a connecting strip.

[0014] Furthermore, the fixing part also includes several protrusions, which are disposed on the two inner walls of the connecting groove along the Z direction.

[0015] The beneficial effects of this utility model are:

[0016] The wiper unit can be detached from the mounting unit. When the wiper unit ages and is damaged due to frequent friction with the windshield, it can be removed and replaced separately, reducing maintenance costs and improving economic efficiency. At the same time, there is no need to remove the mounting unit from the car wiper's mounting steel strip, making maintenance easier and more convenient, and highly practical.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] Example 1:

[0024] This embodiment provides a car windshield wiper blade, including:

[0025] The fixing part 1 has connecting grooves 11 arranged in the X direction on both sides along the Y direction, and mounting grooves 12 arranged in the X direction on one side along the Z direction.

[0026] Wiper section 2, a connecting strip 21 arranged along the X direction is installed on wiper section 2, and the connecting strip 21 is adapted to and snapped into mounting groove 12;

[0027] The baffle 3 is rotatably mounted on the fixed part 1 and is adapted to engage with the mounting groove 12.

[0028] In this technical solution, the car wiper blade is snapped onto the fixed steel strip 5 of the car wiper via two connecting grooves 11. The fixed steel strip 5 is then installed and fixed on the car wiper. The installation structure of the fixed steel strip 5 on the car wiper is existing technology and will not be described in detail. Both the fixing part 1 and the wiper part 2 are made of nitrile rubber, which has stronger wear resistance and better anti-aging performance. The baffle 3 is made of plastic. An installation hole is provided on one end of the fixing part 1 along the X direction. The baffle 3 is rotatably connected to the installation hole. The baffle 3 has a raised strip structure on both sides along the Y direction. A slot is opened on the wall of the mounting groove 12. The baffle 3 is snapped onto the mounting groove 12 by the matching and snapping of the raised strip with the slot.

[0029] When installing the wiper unit 2, first, the baffle 3 on the fixing part 1 is opened to make one end of the mounting groove 12 open in the X direction. Then, the fixing part 1 is opened in the Y direction through the mounting groove 12 so that the connecting strip 21 can be inserted into the mounting groove 12 in the X direction. Then, the fixing part 1 is restored so that the fixing part 1 and the connecting strip 21 are locked together. Finally, the baffle 3 is rotated to lock it onto the fixing part 1 to limit the connecting strip 21 in the X direction, thereby realizing the fixed installation of the wiper unit 2.

[0030] In summary, this structural design enables the wiper unit 2 to be detachably installed on the fixing part 1. When the wiper unit 2 ages and is damaged due to frequent friction with the windshield, it can be disassembled and replaced separately, reducing maintenance costs and improving economic efficiency. At the same time, it eliminates the need to remove the fixing part 1 from the fixing steel strip 5 of the car wiper, making maintenance operations easier and more convenient, and highly practical.

[0031] Example 2:

[0032] This embodiment provides an automotive wiper blade that, in addition to the technical solutions described in the above embodiments, also has the following technical features.

[0033] Furthermore, an arc-shaped clip 4 is provided on one side of the fixing part 1 where the mounting groove 12 is provided along the Z direction, and the arc-shaped clip 4 abuts against the wiper part 2 along the Y direction.

[0034] In this technical solution, there are two arc-shaped clips 4, located on both sides of the wiper part 2 along the Y direction. The two arc-shaped clips 4 are integrally connected to the fixing part 1 and have a certain elasticity. The ends of the arc-shaped clips 4 abut against the wiper part 2, applying a Y-direction clamping force to the wiper part 2, thereby enhancing the installation stability of the wiper part 2 on the fixing part 1. This allows the wiper part 2 to move more stably when wiping the windshield of the car, making it less prone to bending and deformation, and ensuring that the wiper part 2 can wipe away water stains on the windshield.

[0035] Example 3:

[0036] This embodiment provides an automotive wiper blade that, in addition to the technical solutions described in the above embodiments, also has the following technical features.

[0037] Furthermore, the wiper unit 2 is provided with concave arc surfaces 22 on both sides along the Y direction. This structural design enhances the wiper unit 2's resistance to bending deformation and effectively prevents the wiper unit 2 from bending and deforming when moving to wipe the windshield.

[0038] Furthermore, the end of the wiper unit 2 along the Z-direction has a rounded structure. By making the end of the wiper unit 2 that contacts the windshield rounded, the friction experienced by the wiper unit 2 when moving to wipe the windshield is reduced, the abrasion of the wiper unit 2 is reduced, and the durability is improved.

[0039] Example 4:

[0040] This embodiment provides an automotive wiper blade that, in addition to the technical solutions described in the above embodiments, also has the following technical features.

[0041] Furthermore, there are multiple mounting slots 12 and wiper units 2, and each wiper unit 2 is adapted to and connected to each mounting slot 12 via a connecting strip 21.

[0042] In this technical solution, there can be two wiper heads 2, with the mounting groove 12 corresponding to each other and spaced apart along the Y direction. There are also four arc-shaped clips 4, arranged in pairs to limit and support each wiper head 2. This structural design enables a secondary wiping effect on the windshield. Even if one wiper head 2's end along the Y direction is damaged due to frequent friction, the other wiper head 2's end along the same Y direction can still effectively wipe the windshield, thus improving reliability.

[0043] Example 5:

[0044] This embodiment provides an automotive wiper blade that, in addition to the technical solutions described in the above embodiments, also has the following technical features.

[0045] Furthermore, the fixing part 1 also includes a plurality of protrusions 13, which are disposed on the two inner walls of the connecting groove 11 along the Z direction.

[0046] In this technical solution, a plurality of protrusions 13 are provided in the connecting groove 11 of the fixing part 1. The plurality of protrusions 13 are used to abut against the fixing steel strip 5 of the car windshield wiper along the Z direction, thereby increasing the friction between the fixing part 1 and the fixing steel strip 5, thereby enhancing the installation firmness of the fixing part 1 on the fixing steel strip 5.

[0047] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
