Description

Technical Field

[0001] The utility model relates to a multi - angle windshield wiper. Background Art

[0002] During the driving of an automobile, the function of the windshield wiper is to ensure that the driver can maintain a clear vision in rainy days or when there is dirt attached. The traditional windshield wiper design usually adopts a fan - shaped swinging mode, and its scrubbing area is fixed as a fan - shape. However, this design often faces the problem of incomplete scrubbing in actual use, especially when encountering oil stains or other stubborn attachments.

[0003] The scrubbing direction and force of the existing windshield wiper remain unchanged in each swing, which results in the position and state of the attachments on the glass being difficult to change. Due to the consistent direction and force of the scrubbing force, the attachments may not be effectively removed, thus affecting the clarity of the vision and driving safety.

[0004] To address this technical problem, the present application proposes a multi - angle windshield wiper design. This design enables the windshield wiper to change the scrubbing angle and direction during operation by introducing an adjustable swinging mechanism. In this way, the windshield wiper can apply different scrubbing forces at different angles, increasing the change in the force on the attachments, thereby more effectively removing stubborn dirt such as oil stains. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multi - angle windshield wiper. This multi - angle windshield wiper can change the scrubbing angle of the wiper blade during scrubbing, so that the attachments are subjected to forces in various directions, thereby improving the scrubbing effect of the attachments.

[0006] The above - mentioned technical purpose of the utility model is achieved through the following technical solutions:

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0021] In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined. In the present utility model, unless otherwise clearly specified and defined, terms such as "installed", "connected", "connected to", "fixed" and other terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0023] As Figures 1 - 3 shown, a multi-angle windshield wiper includes a wiper motor 1. An installation bracket 2 is arranged on one side of the wiper motor 1. The output end of the wiper motor 1 is connected with a worm 3. Both ends of the worm 3 are connected to the installation bracket 2 by bearings. A worm gear 4 is arranged above the worm 3. When the worm 3 rotates, it can drive the worm gear 4 to rotate.

[0024] A rotating rod 5 is arranged between the worm gear 4 and the installation bracket 2. The rotating rod 5 is connected to the installation bracket 2 by a bearing. A positioning block 6 is arranged at the outer edge position of the worm gear 4. The positioning block 6 is hinged with a connecting rod 7. One end of the connecting rod 7 is hinged with a swinging block 8. The swinging block 8 is hinged with a swing rod 9. A drive shaft 10 is arranged on one side of the swing rod 9. The drive shaft 10 passes through the installation bracket 2 and is connected with a scrubbing device.

[0025] As described above, when the windshield wiper motor 1 operates, it can drive the worm 3 to rotate, and then cause the worm gear 4 to rotate. When the worm gear 4 rotates, the positioning block 6 rotates around the center of the worm gear 4, causing the connecting rod 7 to swing back and forth. Eventually, the swing rod 9 drives the drive shaft 10 to swing back and forth, and its swing angle is 80 - 120 degrees. The reciprocating rotation of the drive shaft 10 enables the scrubbing device to scrub the car glass reciprocally.

[0026] Correspondingly, in order to adjust the scrubbing angle during the scrubbing process. The scrubbing device described in this application includes a drive rod 11 fixedly connected to the end of the drive shaft 10. One end of the drive rod 11 is connected to a windshield wiper blade 12. The reciprocating movement of the drive rod 11 can drive the windshield wiper blade 12 to scrub reciprocally.

[0027] Among them, a rotating shaft 13 is provided in the middle of the windshield wiper blade 12. A first transmission wheel 14 is fixedly sleeved on the rotating shaft 13. Correspondingly, a second transmission wheel 15 is fixedly sleeved on the drive shaft 10. A transmission belt 16 is arranged in cooperation between the first transmission wheel 14 and the second transmission wheel 15. The end of the rotating shaft 13 is connected to the drive rod 11 by a bearing.

[0028] Through the above settings, when the drive shaft 10 reciprocates back and forth, it drives the drive rod 11 to swing back and forth. When the drive rod 11 swings, it can drive the windshield wiper blade 12 to swing back and forth, thus forming a fan-shaped scrubbing area. During the movement process, the rotation of the drive shaft 10 can drive the second transmission wheel 15 to rotate, enabling the power of the transmission belt 16 to be transmitted to the first transmission wheel 14. The first transmission wheel 14 rotates, and then causes the rotating shaft 13 to rotate, finally driving the windshield wiper blade 12 to rotate. According to the above settings, during the reciprocating scrubbing of the windshield wiper blade 12, due to the influence of the rotation of the rotating shaft 13, the scrubbing angle of the windshield wiper blade 12 changes.

[0029] Under the above settings, the overall scrubbing area may be reduced, but for the attachments at various positions on the glass, the scrubbing direction of the attachments can be adjusted during the back-and-forth swing, which can improve the scrubbing effect of the attachments and reduce the scrubbing difficulty of the attachments.

[0030] It should be noted that for some stubborn attachments, manual removal may still be required.

[0031] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
