Description

Technical Field

[0001] This utility model relates to the field of wiper blade welding technology, specifically a novel wiper blade structure. Background Technology

[0002] Windshield wipers, also known as windshield wipers, are important safety accessories installed on the windshield of a car. Their main function is to clear rain, snow, dust, and other contaminants from the windshield that obstruct the driver's view, ensuring a clear view for the driver in all weather conditions and thus guaranteeing driving safety.

[0003] In existing technologies, traditional windshield wiper blades are prone to bending when subjected to pulling or squeezing during the assembly process. This deformation can damage the fit between the blade and the windshield, leading to watermarks, missed areas, or noise during wiping, affecting driving visibility and reducing user comfort. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel welded blade structure for windshield wipers, which solves the problem that traditional windshield wiper blades are prone to bending when subjected to pulling or squeezing during the assembly process.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel welded sheet structure for a windshield wiper, comprising a connecting steel plate, wherein N-type welded sheets are fixedly connected to both ends of the upper surface of the connecting steel plate, and side plates are fixedly connected to the bottom of the front and rear sides of the N-type welded sheets. The top of the inner end face of the N-type welding piece is provided with anti-deformation hooks, and the outer end face of the N-type welding piece is fixedly connected with an anti-fall-off retaining wall. A rubber strip channel is formed between the N-type welding piece and the two side plates.

[0006] Furthermore, the front and rear sides of the upper surface of the connecting steel plate are provided with connection ports for connecting with the middle skin of the windshield wiper.

[0007] Furthermore, the upper surface of the side plate is provided with a bayonet groove for connecting with the wiper end clip.

[0008] Furthermore, the lower surface of the side plate is fixedly connected with a fixing weld point that is welded and fixed to the connecting steel plate.

[0009] Furthermore, the anti-deformation hook has a width of 0.7 mm, a height of 0.5 mm, and a length of 0.8 mm.

[0010] Furthermore, the width of the adhesive strip channel is 6.2 mm, the height of the adhesive strip channel is 1.2 mm, and the length of the adhesive strip channel is 4.8 mm.

[0011] Furthermore, the height of the anti-falling retaining wall is 2mm, and both ends of the bottom of the anti-falling retaining wall are rounded corners with a radius of 0.5mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting an anti-detachment barrier, it can ensure that the rubber strip will not fall off the steel plate in the event of end buckle detachment, thereby avoiding the situation where the steel plate and glass directly scrape and cause wear to the glass surface, thus improving the protection of the glass surface. Furthermore, by setting an anti-deformation hook, it can effectively improve the situation where the rubber strip bends due to pulling or squeezing during the assembly process, resulting in poor wiping effect, improving the fit between the rubber strip and the windshield, thereby improving the stability during the wiping process, improving the clarity of the driver's vision, and thus improving the comfort of using the wipers. Moreover, by setting a rubber strip channel, the overall wiper length and the length of the internal steel plate can be shortened without changing the length of the rubber strip.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a novel welded sheet structure for a windshield wiper, including a connecting steel plate 1, with N-type welded sheets 3 fixedly connected to both ends of the upper surface of the connecting steel plate 1, and side plates 4 fixedly connected to the bottom of the front and rear sides of the N-type welded sheets 3. The top of the inner end face of the N-type welding piece 3 is provided with anti-deformation hooks 7, and the outer end face of the N-type welding piece 3 is fixedly connected with an anti-fall-off retaining wall 6. A rubber strip channel 8 is formed between the N-type welding piece 3 and the two side plates 4.

[0017] The anti-fall-off retaining wall 6 can ensure that the rubber strip will not fall off the steel plate in the event of end buckle detachment, thereby preventing the steel plate and glass from directly scraping and causing wear to the glass surface, and improving the protection of the glass surface.

[0018] The anti-deformation hook 7 effectively improves the situation where the rubber strip bends due to pulling or squeezing during the assembly process, resulting in poor wiping performance. It improves the adhesion between the rubber strip and the windshield, thereby improving the stability during wiping, enhancing the clarity of the driver's vision, and ultimately improving the comfort of using the wipers.

[0019] The rubber strip channel 8 can shorten the overall wiper length and the internal steel plate length without changing the rubber strip length.

[0020] The front and rear sides of the upper surface of the connecting steel plate 1 are provided with connection ports 2 for connecting with the middle skin of the windshield wiper.

[0021] The upper surface of the side plate 4 is provided with a bayonet groove 9 for connecting with the wiper end clip, and the lower surface of the side plate 4 is fixedly connected with a fixing weld point 5 for welding and fixing to the connecting steel plate 1.

[0022] The anti-deformation hook 7 has a width of 0.7mm, a height of 0.5mm, and a length of 0.8mm.

[0023] The width of the adhesive strip channel 8 is 6.2mm, the height of the adhesive strip channel 8 is 1.2mm, and the length of the adhesive strip channel 8 is 4.8mm.

[0024] The height of the anti-falling retaining wall 6 is 2mm, and both ends of the bottom of the anti-falling retaining wall 6 are rounded corners with a radius of 0.5mm.

[0025] During operation, the anti-detachment barrier 6 ensures that the rubber strip will not detach from the steel plate in the event of end buckle detachment, thereby preventing the steel plate from directly scraping the glass and causing wear on the glass surface, thus improving the protection of the glass surface. Furthermore, the anti-deformation hooks 7 effectively prevent the rubber strip from bending due to pulling or squeezing during the assembly process, which could lead to poor wiping performance. This improves the fit between the rubber strip and the windshield, thereby improving the stability during wiping, enhancing the clarity of the driver's vision, and ultimately improving the comfort of using the wipers.
