[0036] Reference below Figure 1 A boneless windshield wiper 1 and a vehicle according to an embodiment of the utility model are described.

[0037] According to the boneless wiper 1 of the first embodiment of the utility model, the boneless wiper 1 comprises: a body 11 and a wiper strip.

[0038] Among them, the main body 11 has a contour plate 111 and a connecting plate 112, the contour plate 111 and the connecting plate 112 define a cavity 11a, the connecting plate 112 has a first positioning portion 1121 arranged adjacent to the center line of the main body 11 and a second positioning portion 1122 arranged away from the center line of the main body 11; at least part of the wiper strip is arranged in the cavity 11a, and the wiper strip has a first limiting portion arranged adjacent to the center line of the main body 11 and a second limiting portion arranged away from the center line of the main body 11, the first limiting portion is connected to the first positioning portion 1121 and is positioned and matched, and the second limiting portion is connected to the second positioning portion 1122 and is positioned and matched.

[0039] Specifically, the contour plate 111 can lay the foundation for the shape contour of the main body 11. For example, the contour plate 111 can be a herringbone structure, so that the outer surface of the contour plate 111 is an arc-shaped surface, which can play a good role in reducing wind resistance. The connecting plate 112 can be arranged at the bottom end of the contour plate 111, and together with the contour plate 111, define a cavity 11a. The cavity 11a can provide an installation position for some other components of the boneless wiper 1 (such as a wiper strip), and fix and support some other components of the boneless wiper 1; at least part of the wiper strip is arranged in the cavity 11a, and the wiper strip has a first limiting portion and a second limiting portion, and the connecting plate 112 has a first limiting portion and a second positioning portion 1122. The first limiting portion is connected and positioned with the first positioning portion 1121, and the second limiting portion is connected and positioned with the second positioning portion 1122, so that the wiper strip and the main body 11 can be fixedly connected and the stability of the connection between the two can be improved.

[0040] It should be pointed out that the first positioning portion 1121 and the first limiting portion are arranged adjacent to the center line of the main body 11, and the second positioning portion 1122 and the second limiting portion are arranged away from the center line of the main body 11. The two sets of positioning and matching structures, the first positioning portion 1121 and the first limiting portion and the second positioning portion 1122 and the second limiting portion, can restrict each other in multiple directions (such as the direction of the center line of the main body 11, the direction of the interval between the second positioning portion 1122 and the center line of the main body 11), so as to improve the anti-detachment performance of the wiper strip. Exemplarily, when the first positioning portion 1121 tends to move outward away from the center line of the main body 11, the first limiting portion is subjected to the force of the first positioning portion 1121 and tends to move outward, and this tendency is further transmitted to the second positioning portion 1122 and the second limiting portion, so that the second positioning portion 1122 and the second limiting portion can generate a reverse force and act on the first positioning portion 1121 and the first limiting portion, thereby limiting the movement of the first positioning portion 1121 and the first limiting portion to ensure the reliability and stability of the connection between the wiper strip and the main body 11.

[0041] According to the boneless wiper 1 of the utility model, the first limiting portion can be connected and positioned with the first positioning portion 1121, and the second limiting portion can be connected and positioned with the second positioning portion 1122, so as to improve the connection reliability and stability between the wiper strip and the main body 11, optimize the anti-detachment performance of the wiper strip, enhance the scraping and cleaning effect of the boneless wiper 1, improve the driving safety in rainy days, and help to extend the service life of the boneless wiper 1, saving economic costs.

[0042] According to some embodiments of the utility model, the wiper strip has a wiper body 121 and a first flange 122. The first flange 122 has a first groove formed on one side facing the connecting plate 112. The first groove defines a first limiting portion. The first positioning portion 1121 is constructed as a first protrusion extending into the first groove.

[0043] Specifically, the first flange 122 has a certain thickness in the extension direction of the centerline of the main body 11, and a first groove is formed on the side of the first flange 122 facing the connecting plate 112. The first groove defines a first limiting portion, and the first positioning portion 1121 is constructed as a first protrusion and is suitable for extending into the first groove. The outer surface of the first protrusion can abut against the inner surface of the first groove. The first protrusion and the first groove can play a positioning role in the assembly between the wiper strip and the connecting plate 112, and can play a good limiting role in the direction of the centerline of the main body 11, and in the direction of the second positioning portion 1122 and the second limiting portion and the centerline of the main body 11, which can improve the assembly positioning accuracy and stability of the wiper strip.

[0044] According to some embodiments of the present invention, a second groove is further provided on the first flange 122 , and the second groove defines a second limiting portion, and the second positioning portion 1122 is configured as a second protrusion extending into the second groove.

[0045] Specifically, at least part of the outer periphery of the first flange 122 can be recessed and formed into a second groove, the second groove defines a second limiting portion, and the second positioning portion 1122 is constructed as a second protrusion and is suitable for extending into the second groove. Similarly, the outer surface of the second protrusion can abut against the inner surface of the second groove. The second protrusion and the second groove can further define the assembly position relationship between the wiper strip and the connecting plate 112, so as to further improve the assembly positioning accuracy of the wiper strip; the second protrusion and the second groove can also further play a good limiting role on the wiper strip in the direction of the center line of the main body 11, and in the direction of the interval between the second positioning portion 1122 and the center line of the main body 11, so as to further improve the assembly stability of the wiper strip.

[0046] According to some embodiments of the present invention, the second groove is formed on a side of the first flange 122 facing away from the connecting plate 112 or is formed on a side of the first flange 122 .

[0047] Specifically, the second groove may be formed on the side of the first flange 122 away from the connecting plate 112, and at least part of the corresponding second protrusion extends in the direction of the center line of the body 11; the second groove may also be formed on the side of the first flange 122, and the side of the first flange 122 may be the outer side of the first flange 122 in the direction of the interval between the second positioning portion 1122 and the center line of the body 11, and at least part of the corresponding second protrusion extends in the direction of the interval between the second positioning portion 1122 and the center line of the body 11. In the form that the second groove is formed on the side of the first flange 122 away from the connecting plate 112 or formed on the side of the first flange 122, the second groove and the second protrusion cooperate to achieve good positioning and limiting effects on the wiper strip, and the relative movement of the first groove and the first protrusion can be limited, so as to optimize the anti-slip performance of the wiper strip.

[0048] According to some embodiments of the present invention, a connecting boss is disposed on one side of the connecting plate 112 away from the cavity 11 a , an accommodating cavity is formed on the connecting boss, and at least a portion of the first flange 122 is disposed in the accommodating cavity.

[0049] Specifically, the connecting plate 112 has a certain thickness in the extension direction of the centerline of the main body 11, and the connecting boss is arranged on the side of the connecting plate 112 away from the cavity 11a. The connecting boss extends in the direction away from the cavity 11a and is provided with a receiving cavity. The receiving cavity is suitable for accommodating at least part of the first flange 122. The inner surface of the receiving cavity can abut against at least part of the outer surface of the first flange 122 to realize the assembly and fixation between the wiper strip and the connecting plate 112. The matching method of the receiving cavity and the first flange 122 is beneficial to improving the convenience and efficiency of assembly between the wiper strip and the connecting plate 112.

[0050] According to some embodiments of the present invention, a first protrusion is formed on a side of the accommodating cavity adjacent to the midline of the body 11 , and a second protrusion is formed on a side of the accommodating cavity away from the midline of the body 11 .

[0051] Specifically, a first protrusion is formed on a side of the accommodating cavity adjacent to the center line of the main body 11, and a second protrusion is formed on a side of the accommodating cavity away from the center line of the main body 11. The first protrusion and the second protrusion are arranged at intervals in a direction opposite to the center line of the main body 11, and at least a portion of the first flange 122 is located between the first protrusion and the second protrusion. When the first protrusion generates a movement tendency relative to the first flange 122 in a direction opposite to the center line of the main body 11, the first protrusion generates a force on the first flange 122, and the first flange 122 generates a force on the second protrusion, so that the second protrusion can generate a reaction force on the first flange 122 to prevent the relative movement between the first flange 122 and the first protrusion in a direction opposite to the center line of the main body 11, thereby effectively improving the stability of the first flange 122 in the accommodating cavity and improving the anti-detachment performance of the wiper strip.

[0052] According to some embodiments of the present invention, the second protrusion is disposed farther away from the connecting plate 112 than the first protrusion.

[0053] Specifically, the second protrusion is arranged farther away from the connecting plate 112 than the first protrusion, and at least a portion of the first flange 122 is located between the first protrusion and the second protrusion. When the first protrusion generates a movement tendency relative to the first flange 122 in the extension direction of the centerline of the main body 11, the first protrusion generates a force on the first flange 122, and the first flange 122 generates a force on the second protrusion, so that the second protrusion arranged away from the connecting plate 112 can generate a reaction force on the first flange 122 to prevent the relative movement between the first flange 122 and the first protrusion in the extension direction of the centerline of the main body 11, thereby further improving the stability of the first flange 122 in the accommodating cavity and improving the anti-detachment performance of the wiper strip.

[0054] According to some embodiments of the present invention, a second flange 123 is further provided at one end of the wiper body 121 extending into the cavity 11 a , and a clamping portion is defined between the second flange 123 and the first flange 122 , and the clamping portion is suitable for clamping and fixing the connecting plate 112 .

[0055] Specifically, the second flange 123 can be arranged at one end of the wiper body 121 extending into the cavity 11a, and a clamping portion is defined between the second flange 123 and the first flange 122. The projection areas of the second flange 123 and the first flange 122 in the extension direction of the centerline of the body 11 are both larger than the projection area of ​​the portion of the wiper body 121 corresponding to the clamping portion. The clamping portion can clamp and fix the connecting plate 112 to achieve the installation and positioning of at least part of the wiper strip in the cavity 11a. At the same time, the second flange 123 and the first flange 122 can also cooperate with each other to play a good limiting role in the extension direction of the centerline of the body 11.
