[0002] As an important accessory installed on the windshield, the wiper is used to sweep away the rain, snow and dust on the windshield that obstructs the view. Therefore, it plays an important role in driving safety. Among the wipers of passenger cars, boneless wiper blades are mostly used.

[0003] In the existing technology, boneless wiper blades are usually connected to the wiper arm using a wiper blade adapter. If the wiper blade is long, the pressure distribution of the steel sheet of the wiper blade on the rubber strip is uneven, and the rubber strip and the glass surface are not tightly attached, which affects the wiping effect. Moreover, if the wiper blade is long, the pressure of the steel strip on the end of the rubber strip is not enough, which will cause serious shaking at the end of the wiper blade. Therefore, the wiper blade can only be used in passenger cars with a small glass area. In other words, the existing boneless wiper blades have a general wiping effect and are greatly limited in their usage scenarios. Utility Model Content

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The embodiment of the present application provides a wiper blade, which can specifically be a frameless wiper blade, having the advantages of high wiping efficiency, good driving visibility and low noise.

[0040] Reference Figure 1 , shows a schematic structural diagram of a wiper blade according to an embodiment of the present application, such as Figure 1 As shown, the wiper blade may specifically include: a rubber strip 10; a support member 11, the support member 11 is connected to the rubber strip 10 along the length direction of the rubber strip 10, and the support member 11 can be used to support the rubber strip 10; a bracket 12, the wiper blade includes at least two brackets 12, each bracket 12 is suitable for connecting with a corresponding adapter 21, and different brackets 12 are arranged at intervals on the support member 11.

[0041] In the embodiment of the present application, at least two brackets 12 are provided on the wiper blade, and one bracket 12 is suitable for connecting with a corresponding adapter 21, that is, the wiper blade can be connected with at least two adapters 21. Since at least two brackets 12 are arranged at intervals on the support member 11, correspondingly, at least two adapters 21 are arranged at intervals on the wiper blade. In this way, at least two adapters 21 can act on the support member 11, so that the pressure of the support member 11 on the rubber strip 10 is evenly distributed, thereby improving the tightness of the fit between the rubber strip 10 and the glass surface and improving the wiping effect of the wiper blade. Moreover, even if the length of the wiper blade is relatively long, under the pressure of at least two adapters 21, the support member 11 can still provide sufficient pressure to the end of the rubber strip 10 to avoid shaking of the end of the wiper blade, thereby expanding the use scenario of the wiper blade.

[0042] In a specific application, the rubber strip 10 can be used to directly contact the glass surface of the vehicle to scrape off impurities such as water or dust on the glass surface. The support member 11 can support the rubber strip 10 and provide pressure to the rubber strip 10 so that the rubber strip 10 can fit the glass surface. The bracket 12 can be connected to the adapter 21 to transfer the pressure of the scraper rod 20 to the support member 11 through the adapter 21, and finally act on the rubber strip 10 through the support member 11, so that the rubber strip 10 can fit the glass surface and achieve a scraping effect.

[0043] In the embodiment of the present application, since there are at least two brackets 12, one bracket 12 can be connected to one adapter 21, so the pressure applied by the scraper rod 20 to the wiper blade can be transmitted to the support member 11 through at least two adapters 21 arranged at intervals, so that the pressure applied by the support member 11 to the rubber strip 10 can act evenly on the rubber strip 10, thereby improving the scraping effect of the rubber strip 10. Moreover, by providing at least two adapters 21 arranged at intervals, even if the length of the wiper blade is long, the end of the wiper blade can be prevented from shaking. In this way, it is convenient to appropriately extend the length of the wiper blade, so that the wiper blade can be applied to vehicles with large glass areas such as trucks and large buses, thereby expanding the use scenarios of the wiper blade.

[0044] Reference Figure 2 , showing Figure 1 The structural diagram of the support member in the scraper shown in FIG. Figure 2 As shown, the support member includes a first section 111, a second section 112 and a third section 113, the second section 112 is connected to the first section 111 and the third section 113 respectively, the first section 111 and the third section 111 are both used to connect the rubber strip 10, and the second section 112 can produce elastic deformation so that the wiper blade can be Figure 3 The natural state and Figure 4In the natural state, the wiper blade is not subjected to pressure from the wiper rod 20, and the second section 112 is naturally curved. In the wiping state, the wiper blade is subjected to pressure from the wiper rod 20, and the second section 112 is deformed to an arc that matches the glass surface, thereby scraping rain or impurities on the glass surface.

[0045] Optionally, the first section 111 and the third section 113 can both produce elastic deformation, and the first section 111 and the third section 113 can cooperate with the second section 112 to deform to increase the overall deformation degree of the support member 11, which is beneficial for the wiper blade to switch more smoothly between the natural state and the wiping state.

[0046] Optionally, the support member 11 may be an integrally formed structure, that is, the first section 111, the second section 112 and the third section 113 may be an integrally formed structure, which can facilitate processing and improve the overall structural strength of the support member 11.

[0047] like Figure 2 As shown, the first section 111 and the third section 113 are arc sections, and the support member 11 is in an "M" shape. In practical applications, the curvature of the arc section 112 can be designed according to the curvature of the glass surface corresponding to its working environment and the structure of the scraper rod 20, so that the rubber strip 10 has a uniform pressure distribution. In this way, the rubber strip 10 can be closely attached to the glass surface, thereby improving the scraping effect of the wiper blade.

[0048] In a specific application, the length and curvature of two adjacent arc segments 112 may be set according to actual conditions. The length and curvature of the two arc segments 112 may be the same or different, and the embodiment of the present application does not impose any special limitation on this.

[0049] It should be noted that in the embodiment of the present application, only the wiper blade 100 is shown to have two brackets 12, and one arc segment 112 is formed between the deformation segment 111 between the two brackets 12 and the end of the support member 11, that is, the support member 11 only includes two arc segments 112. In actual applications, the number of brackets 12 can also be 3, 4 or 6. Correspondingly, the number of arc segments 112 can also include 3, 4 or 6, etc. The embodiment of the present application does not specifically limit the number of brackets 12 and arc segments 112.

[0050] like Figure 1As shown, the bracket 12 is located at the apex of the arc segment 112, so that the pressure exerted by the adapter 21 connected to the bracket 12 on the support 11 can be evenly transmitted to the rubber strip 10 corresponding to the arc segment 112, further improving the force uniformity of the rubber strip 10, so as to further improve the scraping effect of the rubber strip 10 on the glass surface. In addition, the end shaking of the wiper blade can be reduced, and the scraping noise can be reduced.

[0051] In some optional embodiments of the present application, the rubber strip 10 is provided with a deformable curved section at a position corresponding to the second section 112. When the second section 112 of the support member 11 is deformed, the curved section can deform along with the second section 112 to reduce the resistance to deformation of the second section 112, so that the wiper blade can better switch between the natural state and the wiping state.

[0052] Optionally, the material of the bending section may include one of soft rubber materials such as silicone and rubber. In practical applications, when the bending section is made of the above soft rubber material, the bending section is easy to deform and has the advantage of being retractable, so that the bending section can better deform along with the second section 112 of the support member 11.

[0053] Optionally, the support member 11 is a steel sheet. Since the steel sheet has good strength and toughness, when the support member 11 is a steel sheet, the steel sheet can provide a relatively uniform pressure to the rubber strip 10, so that the rubber strip 10 fits tightly to the glass surface, improves the scraping effect, reduces the vibration of the end scraper, and reduces the scraping noise.

[0054] It should be noted that, in practical applications, the support member 11 may also be a copper sheet, a patch, etc., and the embodiment of the present application does not specifically limit the material of the support member 11.

[0055] Optionally, when there is one steel sheet, the steel sheet may be disposed throughout the rubber strip 10 so that the steel sheet can fully support the rubber strip 10. When there are at least two steel sheets, the rubber strip 10 is clamped between at least two steel sheets to further improve the connection reliability between the steel sheet and the rubber strip 10.

[0056] like Figure 1 As shown, the wiper blade may further include two end caps 13, one end cap 13 is connected to one end of the rubber strip 10, and the other end cap 13 is connected to the other end of the rubber strip 10, so as to achieve end protection for the wiper blade.

[0057] In summary, the wiper blade described in the embodiment of the present application may at least include the following advantages:

[0058] In an embodiment of the present application, at least two brackets are provided on the wiper blade, and one of the brackets is used to connect to a corresponding adapter, that is, the wiper blade can be connected to at least two adapters. Since the different brackets are arranged at intervals on the support member. Correspondingly, at least two adapters can be arranged at intervals on the wiper blade. In this way, at least two adapters can act on the support member, so that the pressure of the support member on the rubber strip is evenly distributed, the tightness of the fit between the rubber strip and the glass surface is improved, and the wiping effect of the wiper blade is improved. Moreover, even if the length of the wiper blade is relatively long, under the pressure of at least two adapters, the support member can still provide sufficient pressure to the end of the rubber strip to avoid shaking of the end of the wiper blade, thereby expanding the use scenario of the wiper blade.

[0059] The present application also provides a method Figure 3 and Figure 4 The wiper shown may specifically include: a wiper rod 20, at least two adapters 21 and the wiper blade 100 described in any of the above embodiments; wherein at least two adapters 21 are connected to the wiper rod 20; and one adapter 21 is connected to a bracket 12 on the wiper blade 100.

[0060] In the embodiment of the present application, at least two adapters 21 can act on the support member 11 of the wiper blade 100, so that the pressure of the support member 11 on the rubber strip 10 is evenly distributed, the tightness of the rubber strip 10 and the glass surface is improved, and the wiping effect of the wiper blade 100 is improved. Moreover, even if the wiper blade 100 is long, under the pressure of at least two adapters 21, the support member 11 can still provide sufficient pressure to the end of the rubber strip 10 to avoid the end of the wiper blade 100 from shaking, thereby expanding the use scenarios of the wiper.

[0061] In specific applications, the wiper bar 20 of the wiper can be connected to the vehicle and can swing according to a preset track. The swing of the wiper bar 20 can drive the adapter 21 and the wiper blade 100 to swing together to achieve the scraping and wiping of the glass surface.

[0062] In some optional embodiments of the present application, at least two adapters 21 are connected to the scraper rod 20 at intervals; among the multiple adapters 21, the adapter 21 located at the far end of the scraper rod 20 is the target adapter 21, the target adapter 21 is fixedly connected to the scraper rod 20, and the adapters 21 other than the target adapter 21 are movably connected to the scraper rod 20 and can move along the axial direction of the scraper rod 20. In this way, when the wiper blade 100 is pressed by the scraper rod 20 to fit the glass surface, the distance between the two adapters 21 will be slightly larger. Since the target adapter 21 is fixed on the scraper rod 20, the connection between the remaining adapters 21 and the scraper rod 20 is not fixed, and therefore, the remaining adapters 21 can move freely on the scraper rod 20 along the axial direction of the scraper rod 20 to adjust the distance between the adapters 21, so that the wiper blade 100 can switch between the free state and the wiping state.

[0063] It should be noted that in the embodiment of the present application, the specific structure of the wiper blade 100 is the same as the structure of the wiper blade 100 described in any of the above embodiments, and its beneficial effects are also similar, which will not be described in detail here.

[0064] The present application also provides a vehicle, which may include but is not limited to a passenger car, a large bus, a truck, etc. The present application does not specifically limit the type of the vehicle. The vehicle may include: a windshield wiper as described in any of the above embodiments. Figure 5 and Figure 6 As shown, the wiper 200 can be used to scrape rain or foreign matter off the surface of the glass 30 of the vehicle.

[0065] It should be noted that in the embodiment of the present application, the specific structure of the wiper 200 is the same as the structure of the wiper 200 described in any of the above embodiments, and its beneficial effects are also similar, which will not be repeated here.

[0066] In practical applications, the number of wipers 200 in the vehicle can be set according to actual conditions. Figure 5 As shown, when the area of ​​the glass 30 is small, only one wiper 200 may be provided. Figure 6 As shown, when the area of ​​the glass 30 is relatively large, two wipers 200 may be provided. The embodiment of the present application does not specifically limit the number of wipers 200.
