[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0032] Example 1

[0033] like Figures 1 to 7 As shown, a specific embodiment of this utility model provides an integrated soft-grain wiper. This type of wiper structure has the characteristics of good integrated installation and high stability in use. Specifically, it includes an elastic steel sheet 100, a guide strip 200 and a wiper blade 300 disposed above and below the elastic steel sheet 100, and multiple sets of fixing devices for fixing the wiper blade. The fixing devices include a pair of fixing claws 400. The upper end of each fixing claw 400 is provided with an upper abutment platform 410 and a lower abutment platform 420 arranged in parallel. Each pair of fixing claws 400 is located on both sides of the elastic steel sheet 100 along its length and is arranged opposite each other, so that the upper abutment platform 410 on one fixing claw 400 can abut and fix with the upper end of the lower abutment platform 420 of the other fixing claw 400. The lower end of the fixing claw 400 is provided with a locking claw part 430, which can be locked into the mating groove 310 disposed on the outside of the wiper blade 300.

[0034] like Figures 1 to 6As shown, through the above setting, the elastic steel sheet 100 in the integrated soft cartilage wiper provided in the embodiment is connected with the wiper rubber strip 300 through a plurality of fixers, each of which includes a pair of fixing claws 400, the upper end of which is fixedly connected with the elastic steel sheet 100, and the lower end of which is fixed with the wiper rubber strip 300. In specific implementation, on the one hand, each pair of fixing claws 400 is fixed through the upper abutting table 410 and the lower abutting table 420, and on the other hand, the lower end of the fixing claw 400 is fixed with the wiper rubber strip 300 through the clamping claw part 430, which not only ensures the stability of the connection between the elastic steel sheet 100 and the wiper rubber strip 300, but also makes the integration of the elastic steel sheet 100 and the wiper rubber strip 300 stronger after being connected, and the wiper rubber strip 300 is more evenly subjected to the elastic force of the elastic steel sheet 100, so that the wiping effect is better in use. In actual application, the fixing claw 400 is installed on both sides of the elastic steel sheet 100 and is fixed by ultrasonic welding process, so that the fixing claw 400 and the elastic steel sheet 100 form an integrated structure. Compared with the technical solutions of punching holes in the elastic steel sheet 100 and then installing the wiper rubber strip, and installing the wiper rubber strip through grooves in the elastic steel sheet 100 in the prior art, the fixing structure and the elastic steel sheet 100 fixed in the embodiment are beneficial to further increasing the stability of the connection between the elastic steel sheet 100 and the wiper rubber strip 300, especially after long-term use, the wiper rubber strip 300 and the elastic steel sheet 100 can still maintain relative stability, and the wiper rubber strip 300 is more evenly stressed, thereby improving the wiping effect.

[0035] As shown in Figure 3 and Figure 4 When each group of fixers is installed on both sides of the elastic steel sheet 100, each pair of fixing claws 400 of the fixer needs to be arranged oppositely. In order to facilitate rapid installation, a matching inclined surface is arranged between the upper abutting table 410 and the lower abutting table 420 of each pair of fixing claws 400. The upper abutting table 410 of the fixing claw 400 is provided with a buckle hole 440, and the lower abutting table 420 is provided with a buckle protrusion 450. The relative arrangement of each pair of fixing claws 400 on both sides of the elastic steel sheet 100 in the longitudinal direction can make the buckle protrusion 450 and the buckle hole 440 fit each other. In this way, each pair of fixing claws 400 can make the matching inclined surfaces of the upper abutting table 410 and the lower abutting table 420 match each other through the plug-in mode. After the upper abutting table 410 is located above the lower abutting table 420, the buckle protrusion 450 and the buckle hole 440 are used to realize mutual fixation. After the plug-in type fixation, the fixing claw 400 is preliminarily fixed on the outside of the elastic steel sheet 100, so as to facilitate the subsequent ultrasonic welding process to firmly install it on the elastic steel sheet 100.

[0036] As shown in Figures 3 to 5As shown, in order to make the stable cooperation between the edge of the elastic steel sheet 100 and the fixing claw 400, the embodiment is provided with the embedded groove 470 on the side opposite to the long edge of the elastic steel sheet 100, so that when each pair of the fixing claw 400 is installed in the plug-in mode, the edge of the long side of the elastic steel sheet 100 can be clamped into the embedded groove 470, which can play the positioning and anti-dropping effect and improve the installation stability. At the same time, the embodiment is also provided with the positioning groove 110 on the long sides of the elastic steel sheet 100, which is adapted to the width of the fixing claw 400, and the fixing protrusion 120 is arranged in the positioning groove 110, which can be clamped into the fixing groove 460 arranged on the side of the fixing claw 400. In this way, the positioning groove 110 mainly plays the installation positioning effect of the fixing claw 400, and when the fixing claw 400 is installed in the plug-in mode, it is clamped into the positioning groove 110 of the elastic steel sheet 100, and after being clamped into the positioning groove 110, the fixing protrusion 120 in the positioning groove 110 cooperates with the fixing groove 460 on the side of the fixing claw 400 to further limit the fixing claw 400, so as to avoid the sliding deviation of the fixing claw 400 after being installed in the plug-in mode, which is beneficial to improve the stability of the installation of the fixing claw 400 and the accuracy of the installation position.

[0037] As shown in Figure 7 , the wiper rubber 300 needs to be inserted into the installation position between each pair of the fixing claws 400 from below one end of the elastic steel sheet 100 during installation, and in order to make the wiper rubber 300 be positioned after being installed in place, the embodiment is provided with the positioning outer protrusion 320 on the outside of one end of the corresponding matching groove of the wiper rubber 300, which can be in abutment with the outside of the fixing claw 400 at the end position of the limiting groove, so as to play the limiting effect and avoid the deviation of the wiper rubber 300 along the long direction.

[0038] As shown in Figure 7 , in order to improve the flexibility of the wiper rubber 300, the embodiment is embedded with the supporting strip 330 arranged along the long direction on the long sides of the wiper rubber 300, and the supporting strip 330 has elasticity. The supporting strip 330 can elastically support the wiper rubber 300, so that it can be in uniform contact with the surface of the front windshield of the vehicle during use, thereby improving the wiping effect.

[0039] As shown in Figure 6As shown, since the flow guide strip 200 is installed above the elastic steel sheet 100, in actual implementation, the flow guide strip 200 is arranged in pairs, the inner side of the lower edge of the two flow guide strips 200 is provided with a connecting groove 210 corresponding to the two sides of the longitudinal direction of the elastic steel sheet 100 for clamping the edge of the elastic steel sheet 100, and the inner side of the flow guide strip 200 is also provided with a gap slot 220 corresponding to the installation position of each fixed claw 400, and the end cover 230 is inserted into the end of the flow guide strip 200 corresponding to the end of the elastic steel sheet 100. The flow guide cover 240 is arranged between the two flow guide strips 200 corresponding to the middle of the elastic steel sheet 100. In this way, after the flow guide strip 200 is installed above the elastic steel sheet 100, the edge of the elastic steel sheet 100 is clamped into the connecting groove 210 to fix the flow guide strip 200, and each gap slot 220 can avoid interference with the fixing of the flow guide strip 200. After the flow guide strip 200 is fixed, the end cover 230 is inserted into the two ends, and the flow guide cover 240 is fixed between the two flow guide strips, which plays a good flow guide and shielding protection role.

[0040] As shown in Figure 2 and Figure 5 shown, the wiper structure needs to be connected with the vehicle wiper arm in actual use, and the embodiment is provided with a connecting assembly on the elastic steel sheet 100. The connecting assembly includes a connecting base 500 located at the middle of the upper end of the elastic steel sheet 100 and fixedly connected with the elastic steel sheet 100. The connecting base 500 is provided with a riveting part 510 riveted and fixed with the elastic steel sheet 100 at both ends corresponding to the edge of the elastic steel sheet 100. In this way, the connecting base 500 is fixed at the middle position of the elastic steel sheet 100 and is riveted and fixed with the elastic steel sheet 200 through the riveting part 510, so as to ensure stability after installation. The connecting base 500 is used for connecting the wiper connector structure, and specific reference is made to the connecting structure disclosed in CN108819908A. In the foregoing, the flow guide cover 240 is arranged on the connecting base 500. In order to connect the connecting base 500 with the wiper arm, a connecting port can be arranged on the flow guide cover. When installing the wiper structure, the installation structure at the end of the vehicle wiper arm is inserted into the connecting port to form a detachable connection with the connecting base 500. The connecting base 500 matched with the wiper arm can adopt the existing technical structure, and details are not described herein.
