[0043] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0044] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0045] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0046] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0047] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0048] The wiper blade 100 according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0049] like Figures 1 to 10 As shown, the wiper blade 100 according to the embodiment of the utility model comprises: a wiper body 10 , an adapter 20 and a connecting member 30 .

[0050] Specifically, at least one fixing member 11 is connected to the wiper body 10. The adapter 20 is connected to the wiper body 10 and is spaced apart from the fixing member 11 in the extension direction of the wiper body 10. The adapter 20 is used to connect the drive arm. The connecting member 30 is respectively connected to the fixing member 11 and the adapter 20, and the connecting member 30 can apply a force to the fixing member 11 toward the wiped surface.

[0051] In other words, the wiper 100 according to the embodiment of the utility model is mainly composed of a wiper body 10, an adapter 20 and a connector 30. The wiper 100 can be connected to a wiper arm, and the wiper arm provides a driving force to drive the wiper 100 to wipe and clean the wiped surface. For example, the wiper 100 and the wiper arm can be installed on a vehicle to wipe the glass surface of the vehicle.

[0052] In the wiper 100, the wiper body 10 can be mainly used to wipe the surface to be wiped. The wiper body 10 can be in a long strip shape. It should be noted that the long strip shape of the wiper body 10 can be a straight line shape or an arc shape, which is not limited here. The curvature of the wiper body 10 can be set according to the surface to be wiped.

[0053] The wiper body 10 may be provided with a fixing member 11, which may be integrally formed on the wiper body 10 or connected to the wiper body 10 by, for example, snap connection or screw connection, which is not limited here. The number of fixing members 11 may be one or more, which is not limited here.

[0054] In addition, an adapter 20 may be connected to the wiper body 10. The adapter 20 and the wiper body 10 may be fixedly connected or detachably connected, which is not limited here. The adapter 20 and the fixing member 11 may be arranged along the extension direction of the wiper body 10. When the wiper body 10 extends along a preset straight line direction, the adapter 20 and the fixing member 11 may be arranged along the preset straight line direction. When the wiper body 10 extends along a preset arc direction, the adapter 20 and the fixing member 11 may be arranged along the preset arc direction.

[0055] The adapter 20 can be used to connect the wiper arm, so that the wiper arm can drive the wiper 100 to perform a wiping action. When the wiper 100 wipes the surface to be wiped, the wiper arm can press the wiper body 10 against the surface to be wiped through the adapter 20. At this time, the connection between the adapter 20 and the wiper body 10 can be subjected to a large fitting force. For the sake of convenience, the fitting force can be defined as a first fitting force, which is perpendicular to the surface to be wiped, so that the connection between the adapter 20 and the wiper body 10 is well fitted with the surface to be wiped.

[0056] In some specific embodiments, the adapter 20 may be provided with a mounting hole for connecting with the wiper arm, and the wiper arm may be rotatably connected to the adapter 20 through the mounting hole.

[0057] The adapter 20 and the fixing member 11 can be connected by a connecting member 30, and the connecting member 30 can apply a pressure toward the wiped surface to the fixing member 11. Therefore, the pressure has a component in a direction perpendicular to the wiped surface, and the component can be a second fitting force, which can press the wiper body 10 against and fit it to the wiped surface, which is beneficial to increase the fitting force exerted on the wiper body 10, especially the fitting force exerted on the wiper body 10 at a distance from the adapter 20, so that the wiper body 10 can fit more closely to the wiped surface.

[0058] Optionally, the connecting member 30 may be an elastic member, and when the elastic member connects the adapter 20 and the fixing member 11, the elastic member may be compressed so that the elastic member applies an elastic force toward the scraped surface to the fixing member 11. The connecting member 30 may also be a hydraulic component, and the connection between the hydraulic component and the fixing member 11 may apply pressure to the fixing member 11 toward the scraped surface.

[0059] Therefore, according to the wiper 100 of the embodiment of the utility model, the fixing member 11 and the adapter 20 are arranged on the wiper body 10, and the fixing member 11 and the adapter 20 are connected by the connecting member 30, and the fixing member 11 is applied with a force toward the wiped surface by the connecting member 30, so that there are at least two fitting force points on the wiper body 10, which is conducive to improving the fitting force received by various parts of the wiper body 10, so that the wiper 100 as a whole can be tightly fitted on the wiped surface. In addition, at least two fitting force points can also make the force received by various parts of the wiper body 10 more uniform, which is conducive to designing the wiper 100 to be longer to provide a larger wiping area and a more stable wiping state, thereby improving the wiping efficiency and avoiding problems such as shaking or wiping noise caused by uneven force on the wiper 100.

[0060] In some optional embodiments, the adapter 20 and the fixing member 11 may be metal parts, and the adapter 20 and the fixing member 11 may be welded to the wiper body 10 respectively.

[0061] In some other optional embodiments, the adapter 20 and the fixing member 11 may be plastic parts, and the adapter 20 and the fixing member 11 may be respectively snap-connected and fixed to the wiper body 10 .

[0062] According to some optional embodiments, the connector 30 and the adapter 20 may only serve as a connection. In other embodiments, the connector 30 may apply a force to the adapter 20 toward the wiped surface, further increasing the fitting force at the connection between the adapter 20 and the wiper body 10, so that the wiper 100 fits more closely with the wiped surface, thereby further improving the stability and wiping area of ​​the wiper 100.

[0063] According to an embodiment of the utility model, two fixing members 11 are provided on the wiper body 10 , and in the extending direction of the wiper body 10 , the adapter 20 is located between the two fixing members 11 , and a connecting member 30 is connected between each fixing member 11 and the adapter 20 .

[0064] Specifically, in the extension direction of the wiper body 10, the two fixing members 11 may be spaced apart. The wiper body 10 may have two ends, and a fixing member 11 may be provided between the adapter 20 and each end of the wiper body 10. It should be noted that the fixing member 11 may be provided adjacent to the adapter 20 or at the end of the wiper body 10, which is not limited here, and both can make the wiper body 10 fit more closely to the wiped surface.

[0065] Each fixing member 11 is connected to the adapter 20 via a connecting member 30. In other words, the number of connecting members 30 may be equal to the number of fixing members 11. Each connecting member 30 may apply a force toward the scraped surface to the corresponding fixing member 11 to increase the contact force on the scraping body.

[0066] In this embodiment, two fixing parts 11 are provided on the wiper body 10, and the adapter 20 is provided between the two fixing parts 11, which is beneficial to increase the fitting force points of the wiper body 10, thereby increasing the fitting force applied to the wiper body 10 and making the force applied to various parts of the wiper body 10 more uniform, thereby further improving the stability and wiping area of ​​the wiper 100.

[0067] In some specific embodiments, Figure 1 As shown, each fixing member 11 may be located approximately between the adapter 20 and the corresponding end of the wiper body 10 , and closer to the end of the wiper body 10 , thereby making the force applied to various parts of the wiper body 10 more uniform.

[0068] In some other optional embodiments, more than two fixing parts 11 may be provided on the wiper body 10, which is beneficial to further improve the fitting force of the wiper body 10 and make the fitting force of various parts of the wiper body 10 more uniform, thereby further improving the stability and wiping area of ​​the wiper 100.

[0069] Preferably, the number of the fixing members 11 may be an even number, and the plurality of fixing members 11 may be symmetrically distributed on both sides of the adapter 20 , which is beneficial for more uniform force on various parts of the wiper body 10 .

[0070] According to some other embodiments of the present invention, in the extension direction of the wiper body 10 , the adapter 20 is disposed in the middle of the wiper body 10 , and the distances between the two fixing members 11 and the adapter 20 are equal.

[0071] Thus, the middle of the wiper body 10 can be used as the main force point, which is pressed against the wiped surface under the action of the wiper arm, and the connection between the two fixings 11 and the wiper body 10 can be used as an auxiliary force point, providing additional fitting force to press the two ends of the wiper body 10 against the wiped surface, so that the wiper 100 fits the wiped surface more closely. Setting the distance between the two fixings 11 and the adapter 20 to be the same can make the force at various parts of the wiper body 10 more uniform, which is conducive to improving the stability of the wiper 100.

[0072] In some specific embodiments of the present invention, the connecting member 30 is detachably connected to the adapter 20 and / or the fixing member 11 .

[0073] Specific cases include but are not limited to the following:

[0074] Case 1: The connector 30 is detachably connected to the adapter 20;

[0075] Case 2: The connecting member 30 is detachably connected to the fixing member 11;

[0076] Case 3: The connecting member 30 is detachably connected to the adapter 20 and the fixing member 11 respectively.

[0077] The above-mentioned situations are all conducive to the free installation and disassembly of the connecting member 30, especially the third situation, in which the connecting member 30 can be completely separated from the wiper body 10. Therefore, in the process of assembling the wiper 100, the wiper body 10 can be installed on the wiped surface first, and then the connecting member 30 can be connected to the adapter 20 and the fixing member 11, which is conducive to the wiper 100 to better fit the wiper surface.

[0078] According to some other embodiments of the present invention, the fixing member 11 and the adapter 20 are both provided with grooves 40 facing each other, and two ends of the connecting member 30 extend into the groove 40 of the adapter 20 and the groove 40 of the fixing member 11 respectively.

[0079] Specifically, a groove 40 may be provided on a side of the fixing member 11 facing the adapter 20, and the groove 40 on the fixing member 11 may be recessed in a direction away from the adapter 20. A groove 40 may also be provided on a side of the adapter 20 facing the fixing member 11, and the groove 40 on the adapter 20 may be recessed in a direction away from the corresponding fixing member 11. When there are two fixing members 11 and the adapter 20 is disposed between the two fixing members 11, a groove 40 is provided on a side of the adapter 20 facing each fixing member 11.

[0080] In this embodiment, the end of the connecting member 30 is arranged to extend into the groove 40, so that the connecting member 30 can be limited by the inner surface of the groove 40 to prevent the spring sheet from popping out of the groove 40, which is beneficial to improving the stability of the connection between the spring sheet and the fixing member 11 and the adapter 20, and the connection method between the connecting member 30 and the groove 40 has the advantage of convenient disassembly and assembly.

[0081] According to some optional embodiments of the present invention, the connecting member 30 includes an elastic sheet, a first end of the elastic sheet extends into a groove 40 on the adapter 20 , and a second end of the elastic sheet extends into a groove 40 on the fixing member 11 .

[0082] Specifically, in the extension direction of the wiper body 10, the spring sheet may have two ends, namely a first end and a second end of the spring sheet. The first end of the spring sheet may be inserted into the groove 40 of the adapter 20 so that the spring sheet is connected to the adapter 20. It should be noted that the spring sheet and the adapter 20 may only play a connecting role, or may apply a force to the adapter 20 toward the wiped surface, which is not limited here.

[0083] The second end of the spring sheet can be inserted into the groove 40 of the fixing member 11 so that the spring sheet is connected to the fixing member 11. The spring sheet can have high elasticity and bendability. When the spring sheet is connected between the adapter 20 and the fixing member 11, the spring sheet can be compressed, thereby applying a force toward the wiped surface to the fixing member 11, so that the connection between the wiper body 10 and the fixing member 11 is pressed against the wiped surface by the elastic force of the spring sheet itself, thereby improving the stability and wiping area of ​​the wiper 100.

[0084] Optionally, the material of the spring piece may include but is not limited to high carbon steel or a highly elastic alloy.

[0085] In some specific embodiments of the present invention, the inner surface of the groove 40 includes a groove bottom surface 41, which is opposite to the groove opening 43 of the groove 40. The groove bottom surface 41 includes a first mating surface 411, which is inclined relative to the groove opening 43, and the end face of the spring sheet abuts against the first mating surface 411.

[0086] Specifically, the inner surface of the groove 40 can be mainly composed of a groove bottom surface 41 and a groove wall surface, wherein the groove bottom surface 41 can be the surface of the inner surface of the groove 40 opposite to the groove opening 43, and the groove wall surface can be connected to the groove bottom surface 41 and extend to the groove opening 43.

[0087] A part or the whole of the groove bottom surface 41 may be formed as a first mating surface 411, and the first mating surface 411 is arranged obliquely relative to the notch 43. For example, in the direction of the wiper 100 toward the wiped surface, the first mating surface 411 is inclined toward the notch 43. Therefore, when the end surface of the spring piece abuts against the first mating surface 411, the elastic force applied by the spring piece to the fixing member 11 or the adapter 20 may have a component perpendicular to the wiped surface, thereby pressing the wiper body 10 against the wiped surface, improving the stability and length of the wiper 100, and thus increasing the wiped area of ​​the wiper 100.

[0088] In some optional embodiments, the wiper body 10 may have a length direction, a width direction and a thickness direction, wherein the length direction of the wiper body 10 may be the extension direction of the wiper body 10, the thickness direction of the wiper body 10 may be the direction toward the wiped surface and perpendicular to the wiped surface, and the width direction of the wiper body 10 is perpendicular to the length direction of the wiper body 10 and the thickness direction of the wiper body 10, respectively.

[0089] The groove 40 can penetrate the outer surface of the fixing member 11 or the adapter 20 along the width direction of the wiper body 10 to form a visual window. When installing the spring piece, the connection status of the spring piece in the groove 40 can be observed through the visual window to determine whether the spring piece is installed in place.

[0090] It should be noted that when the wiper body 10 is arc-shaped, the partial surface of the wiper body 10 on the side facing the wiped surface corresponding to the adapter 20 or the fixing part 11 can be defined as a reference surface. For the glass on the vehicle, the curvature of the wiper body 10 is small. Therefore, the reference surface can be approximated to a plane, and the angle between the first mating surface 411 and the wiped surface can be the angle between the first mating surface 411 and the above-mentioned reference surface.

[0091] According to some other embodiments of the present invention, the groove bottom surface 41 also includes a second mating surface 412 and a third mating surface 413, the third mating surface 413 is connected between the second mating surface 412 and the first mating surface 411, the second mating surface 412 is parallel to the first mating surface 411, and the second mating surface 412 is located on the side of the first mating surface 411 close to the wiper body 10, and in the direction from the first mating surface 411 to the second mating surface 412, the third mating surface 413 is inclined toward a direction away from the slot 43.

[0092] Specifically, in the direction of the wiper 100 toward the wiped surface, the first mating surface 411, the third mating surface 413 and the second mating surface 412 in the groove bottom surface 41 are connected in sequence, wherein the first mating surface 411 and the second mating surface 412 are parallel to each other.

[0093] In the direction from the first mating surface 411 to the second mating surface 412, that is, in the direction of the wiper 100 toward the wiped surface, the third mating surface 413 can be inclined in the direction away from the slot 43. Therefore, the third mating surface 413 is inclined relative to the wiped surface, and the connection between the third mating surface 413 and the second mating surface 412 is farther away from the slot 43 than the connection between the third mating surface 413 and the first mating surface 411.

[0094] After the end of the spring piece extends into the slot 43, the end face of the spring piece can first abut against the second mating surface 412, and then slide along the third mating surface 413 to abut against the first mating surface 411, thereby facilitating the assembly of the spring piece and the groove 40 and assisting in determining whether the spring piece is installed in place.

[0095] In some specific embodiments of the present invention, the groove 40 includes a first wall 421 and a second wall 422, the first wall 421 and the second wall 422 are spaced apart in the direction of the wiper 100 toward the wiped surface, the second wall 422 is located on the side of the first wall 421 away from the wiper body 10, the groove bottom surface 41 is respectively connected to the first wall 421 and the second wall 422, the angle between the first mating surface 411 and the first wall 421 is 30°~80°, and / or the second wall 422 is perpendicular to the first mating surface 411.

[0096] Specifically, the groove wall surface may be mainly composed of two inner wall surfaces arranged opposite to each other, and the two inner wall surfaces may be spaced apart in the direction of the wiper blade 100 toward the wiped surface. The two inner wall surfaces are respectively a first wall surface 421 and a second wall surface 422, wherein the first wall surface 421 is closer to the wiper body 10, and the second wall surface 422 is farther from the wiper body 10.

[0097] The first wall surface 421 may be connected to an end of the second mating surface 412 away from the first mating surface 411 , and the second wall surface 422 may be connected to an end of the first mating surface 411 away from the second mating surface 412 .

[0098] The angle between the first mating surface 411 and the first wall surface 421 is set to be 30° to 80°, so that the angle between the first mating surface 411 and the wiped surface is 30° to 80°. Since the larger the angle between the first mating surface 411 and the wiped surface, the larger the elastic force applied by the spring sheet to the fixing member 11 or the adapter 20 and the component of the elastic force in the direction perpendicular to the wiped surface, the larger the fitting force on the wiper body 10 is, which is more conducive to improving the fitting degree between the wiper 100 and the wiped surface. The smaller the angle between the first mating surface 411 and the wiped surface, the larger the elastic force applied by the spring sheet to the fixing member 11 or the adapter 20 and the component of the elastic force in the direction parallel to the wiped surface, which is more conducive to improving the stability of the connection between the spring sheet and the inner surface of the groove 40, and preventing the spring sheet from falling out of the groove 40.

[0099] In addition, the second wall surface 422 can be perpendicular to the first mating surface 411, so that when the end surface of the spring piece abuts against the first mating surface 411, the side surface of the spring piece can be parallel to the second wall surface 422, which facilitates the mating connection between the spring piece and the groove 40. At this time, the side surface of the spring piece and the second wall surface 422 can be fitted, abutted or spaced apart, which is not limited here.

[0100] In some optional embodiments, the first wall surface 421 may be parallel to the scraped surface, and since the second wall surface 422 is perpendicular to the first mating surface 411, the second wall surface 422 is inclined relative to the first wall surface 421. When the angle between the first mating surface 411 and the scraped surface is 30° to 80°, the angle between the first wall surface 421 and the second wall surface 422 may be 10° to 60°.

[0101] According to some optional embodiments of the utility model, a limiting portion 44 is provided on the second wall surface 422, and a matching portion 34 is provided at the end of the spring sheet, and the limiting portion 44 cooperates with the matching portion 34 to limit the spring sheet. Thus, the spring sheet and the groove 40 can be limited by the limiting portion 44 cooperating with the matching portion 34, and the spring sheet is fixed in the groove 40, and the wall spring sheet is separated from the groove 40, which is conducive to improving the stability of the connection between the spring sheet and the groove 40.

[0102] During the assembly of the spring sheet, the end face of the spring sheet may first abut against the second mating surface 412 and then slide along the third mating surface 413 to abut against the first mating surface 411 , while the limiting portion 44 cooperates with the mating portion 34 to limit the spring sheet.

[0103] Optionally, the limiting portion 44 may include but is not limited to a limiting groove and a limiting protrusion, and the matching portion 34 may include but is not limited to a limiting structure that matches the limiting groove or the limiting protrusion.

[0104] According to some other embodiments of the utility model, the matching portion 34 is a limiting hole provided at the end of the spring sheet, the limiting hole penetrates the spring sheet along the thickness direction of the spring sheet, and the limiting portion 44 includes a first extension portion 441 and a second extension portion 442. The first extension portion 441 penetrates the limiting hole along the thickness direction of the spring sheet, and at least part of the second extension portion 442 is clamped outside the limiting hole to limit the spring sheet.

[0105] Specifically, the end of the spring piece may be provided with a limiting hole, which can serve as the matching portion 34 to cooperate with the limiting portion 44 for limiting. The end of the spring piece may be a sheet body, and the limiting hole may penetrate the sheet body along the thickness direction of the spring piece, so that the limiting portion 44 can extend into the limiting hole to limit the spring piece.

[0106] The position-limiting portion 44 may be a protruding structure provided on the second wall surface 422. The position-limiting portion 44 may be mainly composed of two extension portions, namely a first extension portion 441 and a second extension portion 442, wherein one end of the first extension portion 441 may be connected to the second wall surface 422, the other end of the first extension portion 441 may extend toward the first wall surface 421, and the first extension portion 441 may be perpendicular to the second wall surface 422. One end of the second extension portion 442 may be connected to one end of the first extension portion 441 away from the second wall surface 422, and the other end of the second extension portion 442 may extend toward the groove bottom surface 41.

[0107] During the assembly of the spring sheet and the groove 40, the end face of the spring sheet can first abut against the second mating surface 412, at which time, the limiting portion 44 can be opposite to the limiting hole. Then the spring sheet can slide along the third mating surface 413 toward the first mating surface 411. During the sliding process, the second extension portion 442 first enters the limiting hole, and then the first extension portion 441 enters the limiting hole. When the end of the spring sheet abuts against the first mating surface 411, the first extension portion 441 can penetrate the limiting hole. Under the action of the elastic force of the spring sheet itself, the first extension portion 441 can limit the spring sheet in a direction parallel to the second wall surface 422. The second extension portion 442 can be located on the side of the limiting hole away from the second wall surface 422. Thus, the second extension portion 442 can lock the spring sheet in the groove 40 to prevent the spring sheet from popping out of the groove 40, thereby limiting the spring sheet.

[0108] During the process of removing the spring sheet, the end of the spring sheet can be slid along the third matching surface 413 to the second matching surface 412 by external force, so that the limiting portion 44 is separated from the limiting hole, and then the end of the spring sheet is withdrawn from the groove 40.

[0109] In some specific embodiments of the present invention, the angle between the first extension portion 441 and the second extension portion 442 is an obtuse angle, thereby facilitating the assembly of the limiting hole and the limiting portion 44 and simplifying the assembly process.

[0110] According to some optional embodiments of the present invention, the orthographic projection of at least part of the second extension portion 442 on the second wall surface 422 does not overlap with the orthographic projection of the limiting hole on the second wall surface 422 .

[0111] Specifically, the plane where the second wall 422 is located can be defined as a projection plane, and the orthographic projection of a part or all of the second extension portion 442 on the projection plane may not overlap with the orthographic projection of the limiting hole on the projection plane, so that the second extension portion 442 can better lock the spring piece in the direction toward the scraped surface to prevent the spring piece from popping out of the groove 40.

[0112] According to some other embodiments of the utility model, the limiting hole is a rectangular hole. The long side of the rectangular hole can extend in the extension direction of the spring piece, so that when the spring piece slides along the third mating surface 413, the limiting portion 44 can extend into the rectangular hole and slide in the extension direction of the long side of the rectangular hole, so that the spring piece can be locked by the limiting portion 44 when it abuts against the first mating surface 411, effectively preventing the spring piece from popping out of the groove 40 in an accident, which is conducive to improving the stability of the connection between the spring piece and the groove 40.

[0113] In some specific embodiments of the present invention, the spring piece includes a first straight segment 31, a second straight segment 32 and an arc segment 33. The arc segment 33 is arc-shaped and connected between the first straight segment 31 and the second straight segment 32. At least part of the first straight segment 31 extends into the groove 40 located on the fixing member 11, and at least part of the second straight segment 32 extends into the groove 40 of the adapter.

[0114] In other words, the spring piece can be mainly composed of an arc segment 33 and straight segments connected to both ends of the arc segment 33, and the two straight segments can be respectively a first straight segment 31 and a second straight segment 32. Among them, one end of the first straight segment 31 can be connected to the fixing member 11, the other end of the first straight segment 31 can be connected to one end of the arc segment 33, the other end of the arc segment 33 can be connected to one end of the second straight segment 32, and the other end of the second straight segment 32 can be connected to the adapter 20.

[0115] Specifically, part or all of the first straight line segment 31 can extend into the groove 40 of the fixing member 11, the first straight line segment 31 can be parallel to the second wall surface 422 of the groove 40 on the fixing member 11, and the end surface of the first straight line segment 31 can abut against the first mating surface 411 of the fixing member 11 to apply a force to the fixing member 11 toward the scraped surface.

[0116] A portion or all of the second straight line segment 32 can extend into the groove 40 of the adapter 20, the second straight line segment 32 can be parallel to the second wall surface 422 of the corresponding groove 40 on the adapter 20, and the end surface of the second straight line segment 32 can abut against the first mating surface 411 of the corresponding groove 40 on the adapter 20 to apply a force to the adapter 20 toward the scraped surface.

[0117] In this embodiment, the spring sheet includes two straight segments and an arc segment 33, which can facilitate the connection between the groove 40 and the two straight segments. At the same time, the arc segment 33 is compressed to enable the spring sheet to apply an elastic force toward the wiped surface to the fixing member 11 and the adapter 20, so that the fitting force on the wiper body 10 is larger and more uniform, which is beneficial to extending the stability and length of the wiper 100, thereby increasing the wiping area of ​​the wiper 100.

[0118] According to some optional embodiments of the present invention, the length of the first straight segment 31 is greater than that of the second straight segment 32 , which is beneficial to improving the stability of the connection between the spring piece and the fixing member 11 and preventing the spring piece from falling out of the groove 40 of the fixing member 11 .

[0119] In some optional embodiments, the arc segment 33 includes a first arc segment 331 and a second arc segment 332 .

[0120] The first arc segment 331 is convex toward the direction away from the wiper body 10 and one end of the first arc segment 331 is connected to the first straight line segment 31 . The second arc segment 332 is concave toward the direction close to the wiper body 10 and is connected between the first arc segment 331 and the second straight line segment 32 .

[0121] Specifically, the arc segment 33 can be mainly composed of two arc segments, namely the first arc segment 331 and the second arc segment 332. In the direction of the fixing member 11 toward the adapter 20, the first straight segment 31, the first arc segment 331, the second arc segment 332 and the second straight segment 32 are connected in sequence.

[0122] The first arc segment 331 can protrude in the direction away from the wiper body 10, so that the ends of the two straight segments away from the arc segment 33 can extend obliquely toward the wiped surface, thereby the end faces of the straight segments can abut against the first mating surface 411 to apply elastic force toward the wiped surface.

[0123] Since the length of the second straight line segment 32 is smaller than that of the first straight line segment 31, the second arc segment 332 can be recessed toward the direction close to the wiper body 10, so that the inclination of the second straight line segment 32 can be smoother, thereby preventing the second straight line segment 32 from having an excessively large angle with respect to the wiped surface, which may cause the end of the spring piece to easily pop out of the groove 40.

[0124] In some specific embodiments of the present invention, the spring sheet includes a steel sheet, which can be a long sheet structure, and the fixing member 11 and the adapter 20 can be fixedly connected to the steel sheet. The steel sheet has the advantages of simple structure, uniform force, light weight, and is also sun-proof and rust-resistant.

[0125] According to some other embodiments of the utility model, the wiper body 10 includes a mounting surface 121 and a wiping surface 122, the fixing member 11 and the adapter 20 are respectively connected to the mounting surface 121, and the wiper 100 also includes a wiper rubber strip 13, a protective wing 14 and two end caps 15. The wiper rubber strip 13 is arranged on the wiping surface 122. The protective wing 14 is arranged on the mounting surface 121 and extends along the extension direction of the wiper body 10. The two end caps 15 are connected to both ends of the wiper body 10.

[0126] Specifically, a side of the wiper body 10 away from the wiped surface is formed as a mounting surface 121, and a side of the wiper body 10 close to the wiped surface is formed as a wiping surface 122. The fixing member 11, the adapter 20 and the protective wing 14 can be connected to the side of the wiper body 10 away from the wiped surface, and the wiper rubber strip 13 can be connected to the side of the wiper body 10 facing the wiped surface. Optionally, the fixing method between the fixing member 11 or the adapter 20 and the wiper body 10 can include but is not limited to ultrasonic welding or position-limiting clamping.

[0127] In addition, the wiper rubber strip 13 and the protection wing 14 can extend along the extension direction of the wiper body 10 respectively, and the protection wing 14 can protect the wiper rubber strip 13 .

[0128] The wiper arm can apply pressure to the wiper body 10 through the adapter 20 to press the wiper rubber strip 13 against the wiped surface through the wiper body 10. At the same time, the pressure applied by the wiper arm can be transmitted to the fixing member 11 through the connecting member 30. The force applied by the connecting member 30 to the fixing member 11 toward the wiped surface presses the connection between the wiper body 10 and the fixing member 11 and the corresponding part of the wiper rubber strip 13 against the wiped surface, thereby improving the fit between the wiper 100 and the surface to be cleaned and allowing the length of the wiper 100 to be designed to be larger, which is beneficial to improving the wiping efficiency and wiping stability of the wiper 100.

[0129] In addition, the end cover 50 can fasten the wiper body 10 , the wiper rubber strip 13 and the protective wing together, which is beneficial to improving the stability and fit of the wiper 100 .

[0130] The embodiment of the utility model further provides a vehicle, which includes the wiper 100 according to any of the above embodiments. Since the wiper 100 according to the embodiment of the utility model has the above technical effects, the vehicle according to the embodiment of the utility model also has the corresponding technical effects, that is, it is conducive to improving the adhesion force of the wiper body 10 at various locations, so that the wiper 100 as a whole can be closely attached to the wiped surface, and the force at various locations of the wiper body 10 is more uniform, so that the wiper 100 of this embodiment can provide a larger wiping area and a more stable wiping state, thereby improving the wiping efficiency and avoiding problems such as shaking or wiping noise caused by uneven force on the wiper 100.
