[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] refer to Figures 1 to 7 As shown, the wiper uses an inner support and outer buckle end cap, including an end cap 1. The end cap 1 includes a cap end wall 2 and cap side walls 3 on both sides of the cap end wall 2. The inner side wall of the cap side wall 3 is provided with a detachment hook 4. The inner side wall of the cap end wall 2 extends forward along its symmetrical line with an inner support block 5.

[0024] This inner support and outer buckle end cap can be directly installed on the end of the guide rail, thereby simultaneously restricting the sliding of the guide rail relative to the wiper bracket 9 and the wiper blade 8 relative to the guide rail along the length direction. Furthermore, the inner support block 5 on the end cap 1 can be embedded in the isolation groove 704 added to the guide rail 7, which can strengthen the strength of the isolation groove 704 in the middle of the guide rail 7, ensure the stability of the anti-detachment hook 4, and prevent the guide rail 7 from deforming and causing the wiper bracket 9 to be unable to be effectively fastened to the guide rail 7. In addition, in this embodiment, the inner support block 5 can be integrally formed with the end cap 1, resulting in a simple overall structure, easy production, and no additional production process or significant increase in production costs.

[0025] The width of the inner support block 5 decreases linearly from the rear end to the front end; the inner support block 5, which is narrower at the front and wider at the back, helps to be embedded in the isolation groove 704 of the guide rail 7. After being assembled in place, the rear end of the inner support block 5 can be clearance-fitted or interference-fitted with the isolation groove 704 to achieve the supporting function.

[0026] The cross-section of the inner support block 5 is in the shape of an equilateral trapezoid or approximately an equilateral trapezoid, with the long side of the cross-section located at the upper base and the short side located at the lower base. After the inner support block 5 is assembled in place, it can be ensured that the left and right sides of the inner support block 5 can abut against the two sides of the isolation groove 704 to ensure the support effect.

[0027] The extension length of the inner support block 5 is approximately half the length of the cap sidewall 3; and there is a gap between the cap sidewall 3 and the anti-slip hook 4. This structure allows the inner support block 5 to avoid obstructing the anti-slip hook 4 from fastening into the buckle hole 703.

[0028] The inner support block 5 is located on the inner side wall of the upper half of the cap end wall 2, and the top surface of the inner support block 5 is flush with the top surface of the end cap 1; the anti-detachment hook 4 is located on the inner side wall of the upper half of the cap side wall 3, and after the end cap 1 is assembled, it keeps the top surface of the guide rail smooth, making the wiper more aesthetically pleasing.

[0029] The inner sidewall of the cap sidewall 3 is provided with a cap guide rail 6 along its length direction, and the anti-slip hook 4 is provided on the outer end side of the cap guide rail 6; to ensure the connection strength between the cap 1 and the guide rail 1, and to prevent the two from shaking up and down.

[0030] The inner support block 5 is disposed between the two cap guide rails 6, and there is a gap between the inner support block 5 and the cap guide rails 6 on the left and right.

[0031] The anti-detachment hook 4 includes two sets of end faces; one set of end faces includes a first inclined guide surface 401 and a second inclined guide surface 402, the first inclined guide surface 401 and the second inclined guide surface 402 have different inclination angles; the other set of end faces is an anti-detachment hook surface 403, the anti-detachment hook surface 403 is inclined inward; the first inclined guide surface 401 and the second inclined guide surface 402 help the inner support block 5 to be embedded in the isolation groove 704, while the anti-detachment hook surface 403 is inclined inward, making the end cap 1 more securely fastened and less likely to be loosened by impact.

[0032] The gap width H between the two cap sidewalls 3 decreases linearly from the side closer to the cap end wall 2 to the side farther away from the cap end wall 2; the minimum position of the gap width H is less than the width between the side grooves 702, so that the two cap sidewalls 3 can be elastically opened and then inserted into the end of the guide rail 1, improving the connection strength and making the anti-loosening hook 4 more stable when it is fastened into the buckle hole 703.

[0033] The windshield wiper includes at least a guide rail 7, and each end of the guide rail 7 is connected to a cap 1; The bottom of the guide rail 7 is provided with two or more rubber strip mounting grooves 701 arranged in a horizontal direction, and the rubber strip mounting grooves 701 are used to install the wiper rubber strip 8. The left and right sides of the top of the guide rail 7 are provided with side grooves 702 that are open to the side. The side grooves 702 are used to fasten with the wiper bracket 9. Each side groove 702 has a fastening hole 703 on the inner side wall near its end. The anti-detachment hook 4 is fastened in the fastening hole 703. An open-top isolation groove 704 is provided between the two side grooves 702, and the inner support block 5 is tightly embedded in the isolation groove 704.

[0034] The aforementioned guide rail 7 eliminates the need for a bridge-type bracket structure in the wiper structure compared to existing technologies, reducing the weight of the wiper itself. By increasing the number of rubber strip mounting slots 701, it is possible to install two or more wiper rubber strips 8 on the guide rail 1, making the wiper more effective at cleaning the glass and preventing missed wiping when a single wiper rubber strip is deformed or damaged.

[0035] Furthermore, the end cap 1 can be directly fastened to the end of the guide rail 1, which can simultaneously restrict the guide rail 7 from sliding relative to the wiper bracket 9 and the wiper blade 8 from sliding relative to the guide rail 1 along the length direction. The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
