[0002] Windshield wipers, also known as wipers, are devices used to remove raindrops and dust adhering to the windshield of a vehicle, improving the driver's visibility and increasing driving safety. Based on their structure, windshield wipers can be divided into frameless wipers and traditional wipers. Current frameless wipers generally have a steel plate that provides support, with slots in the steel plate for a rubber strip to pass through. When installing the rubber strip, it is necessary to exert force to deform the rubber strip so that it can pass through the slots, which makes the rubber strip more troublesome and affects the speed of rubber strip replacement.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-7 This utility model provides a technical solution: A removable frameless wiper blade for easy maintenance includes a rubber strip 1, a deflector 4, and a clip 5. The rubber strip 1 has grooves 23 on both sides, and a first steel sheet 2 and a second steel sheet 3 are respectively installed in the two grooves 23. One end of the first steel sheet 2 and the second steel sheet 3 are hinged together, and a connecting component is provided between the other ends of the first steel sheet 2 and the second steel sheet 3. A third protrusion 17 extends outward from one end of the first steel sheet 2, and a fourth protrusion 18 extends outward from one end of the second steel sheet 3. A limiting frame 19 is provided on the side of the third protrusion 17. A drive shaft 22 is provided inside 19, and a drive plate 20 is provided on the side of the fourth protrusion 18. A drive hole 21 is opened on the drive plate 20, and the drive shaft 22 and the drive hole 21 are rotatably connected. A receiving hole is formed between the first steel plate 2 and the second steel plate 3, and the rubber strip 1 is located in the receiving hole. The first steel plate 2 and the second steel plate 3 are stuck in the strip groove 23. When the rubber strip 1 needs to be replaced, the connecting assembly is opened, and the first steel plate 2 and the second steel plate 3 are opened directly through the hinge end. The rubber strip 1 loses its limit and can be replaced directly. The replacement speed is relatively fast.

[0017] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the guide plate 4 has a first limiting hole 26, and the buckle 5 has a second limiting hole 27 that matches the first limiting hole 26. A limiting block 28 is inserted between the first limiting hole 26 and the second limiting hole 27. The limiting block 28 is made of rubber. The rubber limiting block 28 is elastic and has a large frictional force with the first limiting hole 26 and the second limiting hole 27. The positioning of the limiting block 28 can be completed through the friction of the rubber. When the limiting block 28 is inserted into place, the positioning of the buckle 5 can be completed.

[0018] Specifically, such as Figure 3 As shown, a locking block 25 is provided on the top side inside the buckle 5, and a slot 24 adapted to the locking block 25 is provided on the top of the guide plate 4. The slot 24 and the locking block 25 are slidably connected. The bottom sides of the first steel sheet 2 and the second steel sheet 3 are both provided with strip grooves 30. The inner side of the buckle 5 is provided with strip protrusions 29 adapted to the strip grooves 30. The strip grooves 30 and the strip protrusions 29 are slidably connected.

[0019] Specifically, such as Figure 5 , Figure 6 and Figure 7 As shown, the connecting assembly includes a first protrusion 6 and a second protrusion 7. One end of the first steel sheet 2 extends outward with the first protrusion 6, and one end of the second steel sheet 3 extends outward with the second protrusion 7. A connecting rod 10 is provided between the first protrusion 6 and the second protrusion 7. A limiting seat 9 is provided on the inner side of the first protrusion 6, and one end of the connecting rod 10 is rotatably connected to the limiting seat 9.

[0020] Specifically, such as Figure 5 , Figure 6 and Figure 7 As shown, the connecting assembly also includes a connecting block 12. The end of the connecting rod 10 away from the limiting seat 9 is provided with the connecting block 12. A limiting groove 8 is opened on the inner side of the second protrusion 7. A limiting block 13 is provided inside the limiting groove 8. A limiting rod 14 is provided on the top of the limiting block 13. One end of the limiting rod 14 passes through the top of the limiting groove 8 and is connected to the limiting plate 16. A second spring 15 is provided between the top of the limiting block 13 and the limiting groove 8. A first spring 11 is provided between the connecting rod 10 and the first protrusion 6. Both sides of the connecting block 12 are wedge-shaped surfaces, and both sides of the limiting block 13 are wedge-shaped surfaces. The contact surfaces of the limiting block 13 and the connecting block 12 are adapted to each other. When the connecting block 12 moves to the other side of the limiting block 13, under the action of the first spring 11, the connecting block 12 and the limiting block 13 fit together. When the connecting block 12 moves into the limiting groove 8, the first steel plate 2 and the second steel plate 3 form a whole under the cooperation of the limiting block 13 and the limiting groove 8.

[0021] In summary, the frameless wiper provided in this embodiment is easy to maintain. When the frameless wiper needs to replace the rubber strip 1, first remove the limiting block 28 from the first limiting hole 26 and the second limiting hole 27, then remove the buckle 5, and then remove the guide plate 4. At this time, pull the connecting rod 10, and the connecting block 12 slides out from the limiting groove 8. At this time, the first steel plate 2 and the second steel plate 3 can be unfolded, and then the rubber strip 1 can be directly removed and replaced.
