AI Technical Summary

Technical Problem

In traditional wiper structures, the wiper blade lacks clamping force at the mounting position, resulting in a lack of tight contact between the wiper blade and the windshield, thus failing to effectively remove rainwater or dirt.

Method used

A pressure strip is installed at the bottom of the mounting base. The pressure strip presses against the scraper in a direction away from the mounting base, so that the scraper is in contact with the glass surface. The pressure is enhanced by the combination of the support plate and the pressure strip, ensuring that the scraper is flat against the glass surface.

Benefits of technology

This achieves a tight bond between the wiper blade and the glass surface, improving the effectiveness of wiping away rainwater and dirt.

Description

Technical Field

[0001] This application relates to windshield wipers, and more particularly to a wiper structure that applies force evenly to a car windshield. Background Technology

[0002] In general, windshield wipers are connected to the wiper drive arm of the car and mounted on the outer side of the windshield. The wiper drive arm applies force to the wiper blade, causing the wiper to swing repeatedly on the glass surface to remove rainwater or dirt and other foreign objects.

[0003] Furthermore, in traditional windshield wiper structures, the bottom of the mounting bracket used to attach the drive arm is hollowed out. The metal elastic sheet at this hollowed-out position does not apply pressure to the wiper blade, resulting in insufficient pressure on the wiper blade at the mounting bracket position. Consequently, the wiper blade cannot maintain a tight seal with the windshield, hindering the removal of rainwater or dirt. Therefore, the inventor's research motivation for this application is to find a way to ensure a tight seal between the wiper blade and the windshield, thereby achieving a reliable rainwater removal effect.

[0004] In view of this, the inventors of this application have devoted themselves to the study of the above-mentioned prior art and, in conjunction with the application of theoretical principles, have made every effort to solve the above-mentioned problems, which have become the target of the inventors' improvements. Summary of the Invention

[0005] The purpose of this application is to provide a wiper structure that can reinforce the pressure force, so that the wiper blade can press evenly against the glass surface to make it flat against the glass surface, so as to facilitate the wiping of rainwater or foreign objects from the glass surface.

[0006] To achieve the above objectives, this application provides a windshield wiper structure that can reinforce the pressure force, including a mounting bracket, a support plate, a wiper blade, and at least one pressure strip. The mounting bracket includes a mounting base and a pivot shaft disposed on the mounting base. The support plate is attached to the bottom side of the mounting base and extends to the opposite side of the mounting base. The wiper blade is attached to the bottom surface of the support plate, and the pressure strip is disposed on the bottom side of the mounting base and presses against the wiper blade in a direction away from the mounting base to adhere to the glass surface.

[0007] Compared to the shortcomings of existing wiper blade structures that lack pressure at the mounting position, the wiper structure of this application includes a pressure strip disposed at the mounting position. The pressure strip presses against the wiper blade in a direction away from the mounting position, causing the wiper blade to adhere to the glass surface, thus facilitating the wiping of rainwater or foreign objects from the glass surface. Furthermore, the pressure strip of this application embodiment can be integrally formed with the support plate and adjacent to the mounting position, or it can be disposed on the bottom side of the mounting frame through riveting, fastening, or welding. In addition, the pressure strip can also be directly connected to the bottom of the mounting position through riveting, fastening, or welding. This strengthens the pressure of the support plate at the hollowed-out position at the bottom of the mounting position, allowing the support plate to press the wiper blade more evenly and flat against the glass surface, thus facilitating the wiping of rainwater or foreign objects from the glass surface.

[0028] The detailed description and technical content of the embodiments of this application are illustrated below with reference to the accompanying drawings. However, the drawings are provided for reference and illustration only and are not intended to limit the embodiments of this application.

[0029] Please refer to Figures 1 to 3 These are perspective views and two exploded perspective views of a windshield wiper structure with reinforced pressure according to an embodiment of this application. The windshield wiper structure 1 with reinforced pressure according to this embodiment includes a mounting bracket 10, a support plate 20, a wiper blade 30, and at least one pressure strip 40. The support plate 20 is attached to the bottom side of the mounting bracket 10. The wiper blade 30 is attached to the bottom surface of the support plate 20. The pressure strip 40 is disposed on the bottom side of the mounting bracket 10, thereby constituting the windshield wiper structure 1 with reinforced pressure.

[0030] The mounting bracket 10 includes a mounting base 11 and a pivot shaft 12 disposed on the mounting base 11. The pivot shaft 12 is used to engage a drive arm (not shown) to drive the wiper structure 1 to wipe rainwater or foreign objects off the glass surface.

[0031] The support plate 20 is made of metal and has elastic deformation capacity. It is attached to the bottom side of the fixing seat 11 and extends to the opposite side of the fixing seat 11. In this embodiment, the support plate 20 includes a pair of elastic sheets 21 extending to the opposite side of the fixing seat 11.

[0032] The scraper 30 is made of rubber and is attached to the bottom surface of the support plate 20. The scraper 30 is pressed against the glass surface by the support plate 20.

[0033] Furthermore, the pressure strip 40 is disposed on the bottom side of the fixing base 11 and presses against the scraper 30 in a direction away from the fixing base 11 to adhere to the glass surface (not shown in the figure).

[0034] In one embodiment of this application, the wiper structure 1 further includes a pair of covers 50, an accessory seat 60, and two or more fastening frames 70. The pair of covers 50 are correspondingly fitted onto the pair of elastic pieces 21, and each cover 50 has a pair of through slots 51. The two sides of each elastic piece 21 are respectively inserted into the pair of through slots 51 to be attached to the support plate 20. In addition, the accessory seat 60 is attached to the fixing base 11 and sandwiched between the pair of covers 50.

[0035] In this embodiment, the fastening frames 70 are U-shaped fasteners. Furthermore, each elastic piece 21 has two or more spaced-apart locking grooves 210, and the fastening frames 70 pass through these locking grooves 210 to engage with the scraper strip 30. Accordingly, the top of the scraper strip 30 is secured in the fastening frames 70, and the scraper strip 30 is engaged with the bottom surface of the support plate 20 through the fastening frames 70.

[0036] Please continue reading. Figure 4 and Figure 5 This is a schematic diagram and cross-sectional view of the wiper blade assembly according to an embodiment of this application. In one embodiment of this application, the blade 40 is an elastically bent sheet. Furthermore, the support plate 20 includes a pair of elastic sheets 21, and the number of blades 40 is a pair. The pair of blades 40 are respectively attached to the pair of elastic sheets 21 and abut against the fixing base 11. Specifically, the blade 40 is located at one end of the elastic sheet 21, and the blade 40 is integrally formed with the elastic sheet 21.

[0037] It should be noted that, since the bottom of the fixing base 11 is a hollow part, and the pair of elastic pieces 21 are respectively fixed on both sides of the fixing base 11, the support plate 20 does not press down on the wiper blade 30 at the middle position of the fixing base 11. Therefore, the wiper blade 30 lacks pressing force at the fixing base 11. In this regard, the wiper structure 1 of this application provides a pressure strip 40 at the bottom of the fixing base 11, thereby strengthening the pressing force of the support plate 20 at the fixing base 11, so that the support plate 20 can press down on the wiper blade 30 more evenly and flat against the glass surface, which is beneficial for wiping rainwater or foreign objects from the glass surface.

[0038] Please refer to another source. Figure 6 This is a combined cross-sectional view of another embodiment of the windshield wiper structure that can reinforce the pressure force according to the present application. This embodiment is largely the same as the previous embodiment, with the wiper structure 1a including a fixing frame 10a, a support plate 20a, a wiper blade 30a, and at least one pressure strip 40a. The difference between this embodiment and the previous embodiment lies in the shape and arrangement of the support plate 20a and the pressure strip 40a.

[0039] In this embodiment, the support plate 20a is an integrally formed metal spring sheet that extends to the opposite side of the fixing frame 10a. Furthermore, there is a pair of pressure strips 40a. These pair of pressure strips 40a are disposed opposite each other on the bottom side of the fixing frame 10a. It should be noted that the pair of pressure strips 40a can be disposed on the bottom side of the fixing frame 10a by means of riveting, fastening, or welding.

[0040] Please refer to again Figure 7 This is a combined cross-sectional view of another embodiment of the windshield wiper structure that can reinforce the pressure force according to the present application. This embodiment is largely the same as the previous embodiment, with the wiper structure 1b including a fixing frame 10b, a support plate 20b, a wiper blade 30b, and at least one pressure strip 40b. The difference between this embodiment and the previous embodiment lies in the shape and arrangement of the support plate 20b and the pressure strip 40b.

[0041] In this embodiment, the fixing frame 10b includes a fixing base 11b and a pivot shaft 12b. The support plate 20b includes a pair of elastic sheets 21b extending on opposite sides of the fixing frame 10b. Furthermore, there is a pair of pressure strips 40b. The pair of pressure strips 40b are connected to the bottom of the fixing base 11b and are located opposite each other on both sides of the fixing frame 10b. Similarly, the method of joining the pair of pressure strips 40b is not limited; they can be joined by riveting, fastening, or welding to the bottom side of the fixing base 11b.

[0042] The above description is only a preferred embodiment of this application and does not limit the scope of protection of this application. Therefore, all equivalent technical and technical changes that utilize the content of this application specification and drawings are also included in the scope of protection of this application.
