A boneless wiper

Abstract

This invention relates to a frameless windshield wiper, comprising a base and a steel sheet. The base has a groove, and the steel sheet is installed within the groove. A wiper blade is fixed to the bottom of the steel sheet, and a bracket is fixed to the steel sheet. Support arms are provided on both sides of the bracket, and slots are provided at the ends of the support arms, where the wiper blade is clamped and fixed. By adding the bracket, the clamping force generated by the deformation of the steel sheet is first transmitted to the bracket, then through the bracket to the two support arms, and finally through the support arms to the wiper blade. This method shortens the distance of direct transmission of the deformation force of the steel sheet, enhances the clamping force at the wiper end, and avoids poor wiping performance at the wiper end.

Description

Technical Field

[0001] This invention relates to a frameless windshield wiper. Background Technology

[0002] Windshield wipers are installed in front of a car's windshield to remove rainwater and dust, preventing obstructed vision and ensuring safe driving. Frameless wipers are particularly suitable due to their lightweight, flexibility, and ease of installation.

[0003] Existing frameless wipers use a steel blade with a certain curvature to achieve a close fit with the glass. However, in wipers with a longer length, the pressure at both ends will be significantly reduced, resulting in poor rain removal performance. Summary of the Invention

[0004] The purpose of this invention is to provide a frameless windshield wiper that can enhance the clamping force at the wiper tip and avoid poor wiping performance at the wiper tip.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a frameless windshield wiper, comprising a base and a steel sheet. The base has a groove, the steel sheet is installed within the groove, a wiper blade is fixed to the bottom of the steel sheet, a bracket is fixed to the steel sheet, support arms are provided on both sides of the bracket, and slots are provided at the ends of the support arms, where the wiper blade is clamped and fixed. By adding the bracket, the clamping force generated by the deformation of the steel sheet is first transmitted to the bracket, then through the bracket to the two support arms, and finally through the support arms to the wiper blade. This method shortens the distance of direct transmission of the deformation force of the steel sheet, enhances the clamping force at the wiper end, and avoids poor wiping performance at the wiper end.

[0006] In a preferred embodiment of the present invention, the wiper blade has strip-shaped grooves on both sides, and steel strips are disposed within the strip-shaped grooves. The steel strips serve to increase the elasticity and toughness of the wiper blade, allowing it to better withstand force.

[0007] In a preferred embodiment of the present invention, there are four supports, which are symmetrically distributed about both sides of the base.

[0008] In a preferred embodiment of the present invention, the sheath includes two sleeve portions (left and right) and a connecting strip. The connecting strip connects the two sleeve portions, and each sleeve portion has a cavity with one open end. The sleeve portion is inserted into the end of the steel sheet through the opening, and the connecting strip connects the open ends of the two sleeve portions. By adding the connecting strip, the two sleeve portions are connected together, so that both sleeve portions have a tension force towards the middle, allowing the two ends of the sheath to be pressed tightly against the steel sheet, thus preventing the sheath from easily detaching from the ends of the steel sheet.

[0009] In a preferred embodiment of the present invention, the connecting strip passes through the groove and is located between the steel sheet and the bottom surface of the sheath groove.

[0010] In a preferred embodiment of the present invention, a wiper cover is further included, which is fitted over the base. The wiper cover has connection ports at both ends, and the opening of the sleeve mates with the connection ports. This allows the cover and the wiper cover to be integrated into one unit.

[0011] In a preferred embodiment of the present invention, the base is provided with a connector.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: After adding the bracket, the clamping force generated by the deformation of the steel sheet is first transmitted to the bracket, then transmitted to the two support arms through the bracket, and then transmitted to the wiper blade through the support arms. This method shortens the distance of direct transmission of the deformation force of the steel sheet, which can enhance the clamping force at the end of the wiper and avoid poor wiping effect at the end of the wiper.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Please see Figure 1-7 The present invention provides a technical solution: a frameless wiper, comprising a base 1, a steel sheet 2 and a protective sleeve 3, wherein a groove 11 is provided at the bottom of the base 1 and a connector 6 is provided on the base 1.

[0023] The steel sheet 2 is fixed with a bracket 7. There are 4 brackets, and the 4 brackets 7 are symmetrically distributed about both sides of the base 1.

[0024] The bracket 7 has support arms 71 on both sides, and each support arm 71 has a slot 72 at its end, in which the wiper blade 4 is clamped and fixed. The wiper blade 4 has strip grooves 41 on both sides, and steel strips 42 are installed within these grooves. The steel strips increase the elasticity and toughness of the wiper blade, allowing it to better withstand force.

[0025] With the addition of the bracket, the clamping force generated by the deformation of the steel sheet is first transmitted to the bracket, then through the bracket to the two support arms, and finally through the support arms to the wiper blade. This method shortens the distance of direct transmission of the deformation force of the steel sheet, which can enhance the clamping force at the end of the wiper and avoid poor wiping performance at the end of the wiper.

[0026] The steel sheet 2 is installed in the groove 11, and a wiper blade 4 is fixed to the bottom of the steel sheet 2. The sleeve 3 includes two sleeve portions 31 on the left and right and a connecting strip 32. The connecting strip 32 connects the two sleeve portions 31. Each sleeve portion 31 has a cavity 3b with an opening 3a at one end. The sleeve portion 31 is inserted into the end of the steel sheet 2 through the opening 3a. The connecting strip 32 connects the opening 3a ends of the two sleeve portions 31. The connecting strip passes through the groove and is located between the steel sheet and the bottom surface of the groove of the sleeve.

[0027] It also includes a wiper cover 5, which is fitted over the base 1. The wiper cover 5 has connection ports 51 at both ends, and the opening 3a of the sleeve 31 mates with the connection ports 51. This method allows the cover and the wiper cover to be integrated into one unit.

[0028] By adding a connecting strip, the two sleeves are connected together, so that both sleeves have a tension force towards the middle, which can make the two ends of the sheath press tightly against the steel sheet, so that the sheath is not easy to come off from the two ends of the steel sheet.
