In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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.

[0041] Reference below Figure 1-Figure 5 The present invention describes an end cover assembly of a boneless wiper according to an embodiment of the present invention, in which the end cover 1 and the spring leaf 2 are snap-fitted together, and the installation method is simple. The end cover 1 and the spring leaf 2 define a rubber strip plug-in cavity 3 after being snap-fitted, so that the rubber strip 4 can be plugged into the rubber strip plug-in cavity 3 or pulled out from the rubber strip plug-in cavity 3, thereby realizing the separate disassembly and replacement of the rubber strip 4, which is beneficial to reducing the use cost of the boneless wiper 100.

[0042] like Figure 1-Figure 5 As shown, the end cap assembly of the boneless wiper according to the embodiment of the present invention comprises: an end cap 1 and a reed 2. It should be noted that the boneless wiper 100 comprises a wiper bracket 5, the reed 2 can be relatively fixed to the wiper bracket 5, and the end cap 1 can be arranged at the end of the reed 2, that is, the end of the reed 2 can be connected and fixed to the end cap 1.

[0043] Among them, the reed 2 is plugged into the end cover 1, and the reed 2 and the end cover 1 define a rubber strip plug-in cavity 3, that is, the end cover 1 forms an inner cavity of the end cover 1, and the end of the reed 2 can be plugged into the inner cavity of the end cover 1. That is, the reed 2 and the end cover 1 can be two independent components, and when the boneless wiper 100 is installed, the end of the reed 2 can be plugged into the end cover 1, and after the reed 2 and the end cover 1 are plugged and fixed, the two together define a rubber strip plug-in cavity 3, and the rubber strip plug-in cavity 3 is used to plug the rubber strip 4.

[0044] The end cover 1 is provided with a first clamping portion, and the spring leaf 2 is provided with a second clamping portion, and the first clamping portion is clamped with the second clamping portion and is limitedly matched along the plugging direction of the spring leaf 2. That is to say, after the spring leaf 2 is plugged into the end cover 1, it can be limitedly fixed by the clamping cooperation of the first clamping portion and the second clamping portion, and the first clamping portion and the second clamping portion are set to be limited along the plugging direction of the spring leaf 2 after clamping, so that the spring leaf 2 is limitedly fixed to the end cover 1, that is, the spring leaf 2 is limited to automatically fall off from the end cover 1, so that the two form an integral structure, the structure is simple, and the installation is convenient.

[0045] In other words, the reed 2 in the present invention will not be relatively detached after being connected to the end cover 1, and when the rubber strip 4 is disassembled relative to the end cover assembly, the reed 2 and the end cover 1 are also in a relatively clamped state. Therefore, the rubber strip 4 can be disassembled independently relative to the end cover assembly, that is, the rubber strip 4 can be flexibly disassembled and installed independently, thereby reducing the cost of using the rubber strip 4. There is no need to replace the reed 2 or the end cover assembly as a whole together with the rubber strip 4, which greatly reduces the use cost of the boneless wiper 100.

[0046] It should be noted that, when using a conventional boneless wiper, the rubber strip is partially fixedly connected to the spring, specifically, a lug is provided on the end cover, a matching notch is provided on the rubber strip, and the spring and the end cover are connected by means of the lug and the matching notch. When removing the rubber strip, the spring and the end cover need to be removed, which may easily cause damage to the lug and the matching notch, and is not conducive to repeated use. The rubber strip 4 in the present invention is plugged into the rubber strip plug-in cavity 3, which is convenient for installation and removal, and the spring 2 and the end cover 1 do not need to be disassembled during the disassembly and assembly of the rubber strip 4, that is, the spring 2 and the end cover 1 do not need to be repeatedly disassembled and installed during the use of the rubber strip 4, so that the structural damage at the matching point between the spring 2 and the end cover 1 will not be caused, that is, the problem of damage to the lug and the matching notch in the traditional design will not occur, which is conducive to improving the structural safety of the boneless wiper 100.

[0047] According to the end cover assembly of the boneless wiper embodiment of the present invention, the reed 2 is snap-fitted with the end cover 1, with a simple structure and easy installation. After the reed 2 is snap-fitted with the end cover 1, a rubber strip plug-in cavity 3 is defined, so that the end of the rubber strip 4 can be flexibly plugged into or pulled out of the rubber strip plug-in cavity 3, thereby realizing the separate disassembly and installation of the rubber strip 4, which is beneficial for the separate disassembly and replacement of the rubber strip 4 when the structure of the rubber strip 4 is damaged, and the problem of damage to the reed and the end cover at the lug and the matching notch in the traditional design will not occur, which is beneficial for realizing multiple disassembly and assembly of different reeds 2, thereby reducing the use cost of the boneless wiper 100.

[0048] In some embodiments, there are at least two first clamping parts and at least two second clamping parts, and at least two first clamping parts are clamped together with at least two second clamping parts in a one-to-one correspondence, that is, the spring leaf 2 and the end cover 1 can be clamped together at at least two positions to improve the reliability of the clamping fit between the spring leaf 2 and the end cover 1.

[0049] It should be noted that when removing and installing the rubber strip 4, the force generated by the rubber strip 4 in the rubber strip insertion cavity 3 will act on the reed 2 and the end cover 1, and by providing at least two sets of snap-fit ​​structures for snap-fitting, the fitting position of the reed 2 and the end cover 1 can be made more stable, that is, when removing or installing the rubber strip 4, the rubber strip 4 will not push the reed 2 and the end cover 1 to be relatively separated, thereby facilitating the accurate separate removal of the rubber strip 4, reducing the disassembly cost, and avoiding the problem of excessive force at the single fitting point of the reed 2 and the end cover 1 causing structural damage, thereby improving the safety of the boneless wiper 100.

[0050] That is to say, the first clamping parts and the second clamping parts can be set to two, three, four or even more. Among them, multiple first clamping parts can be distributed at intervals on the end cover 1, and multiple second clamping parts can be distributed at intervals on the spring 2, so that the spring 2 and the end cover 1 are clamped and matched at multiple intervals, thereby generating multiple limiting forces at different positions or angles, ensuring the installation reliability of the spring 2 and the end cover 1.

[0051] In some embodiments, at least two first clamping parts are spaced apart along the plugging direction of the spring leaf 2, that is, at least two first clamping parts can be snap-fitted with the second clamping part at at least two positions in the plugging direction of the spring leaf 2, and / or at least two second clamping parts are spaced apart along the plugging direction of the spring leaf 2, that is, at least two second clamping parts can be snap-fitted with the first clamping part at at least two positions in the plugging direction of the spring leaf 2. In other words, when at least two first clamping parts and at least two second clamping parts are snap-fitted and distributed in sequence in the plugging direction of the spring leaf 2, the spring leaf 2 can form a multi-level limit anti-slipping in the cooperation with the end cover 1.

[0052] Thus, when the first clamping part and the second clamping part are both provided with two and they are matched one to one to form two groups of clamping structures, and at the same time, the two groups of clamping structures are spaced apart in the plugging direction of the spring leaf 2, so that a two-level anti-dropout clamping connection can be formed between the spring leaf 2 and the end cover 1. Similarly, when the first clamping part and the second clamping part are both provided with two and they are matched and distributed as described above, a three-level anti-dropout clamping connection can be formed, and even when the first clamping part and the second clamping part are both provided with more, more levels of anti-dropout clamping connection can be formed.

[0053] Among them, by setting at least two snap-fits, at least two levels of anti-slipping can be formed between the spring leaf 2 and the end cover 1. At the same time, the at least two-level anti-slipping design can form a two-level interlocking, thereby realizing the locking and fixation of the spring leaf 2 and the end cover 1, and improving the assembly reliability of the two.

[0054] In some embodiments, in the projection along the plug-in direction of the spring leaf 2, at least two first clip-on portions are staggered, that is, when the at least two first clip-on portions are clipped together with the corresponding second clip-on portions, the corresponding clip-on limiting forces of the at least two first clip-on portions act on different positions in the direction intersecting the plug-in direction; and / or, in the projection along the plug-in direction of the spring leaf 2, at least two second clip-on portions are staggered, that is, when the at least two second clip-on portions are clipped together with the corresponding first clip-on portions, the corresponding clip-on limiting forces of the at least two second clip-on portions act on different positions in the direction intersecting the plug-in direction.

[0055] Specifically, in the projection along the insertion direction of the spring leaf 2, when at least two first clamping portions are staggered and at least two second clamping portions are staggered, the projections of the mating positions of the at least two first clamping portions and the at least two second clamping portions are staggered. Figure 1 and Figure 2 As shown, the plug-in direction of the spring piece 2 is the left and right direction in the figure, wherein there are two first clamping parts and two second clamping parts, and the two first clamping parts are staggered along the left and right direction, and are distributed at intervals along the up and down direction in the figure, that is, distributed along the width direction of the end cover 1, and at the same time, the two second clamping parts are staggered along the left and right direction, and are distributed at intervals along the up and down direction in the figure, that is, distributed along the width direction of the spring piece 2.

[0056] Therefore, after the spring leaf 2 and the end cover 1 are clamped and limited, the spring leaf 2 can be clamped with the end cover 1 at different positions in the width direction, which can avoid the end cover 1 and the spring leaf 2 from being tilted relative to each other when the rubber strip 4 is inserted into or pulled out of the rubber strip insertion cavity 3. This can avoid the spring leaf 2 or the end cover 1 from rotating relative to a single clamping position and becoming tilted and unstable, thereby improving the stability of the cooperation between the spring leaf 2 and the end cover 1.

[0057] In some embodiments, at least one of the first clamping parts and one of the second clamping parts are clamped and matched with the end cover 1 at the end of the reed 2, that is, when the reed 2 is inserted into the deepest part of the end cover 1, the first clamping part and the second clamping part can be clamped and matched, so that the reed 2 and the end cover 1 are clamped at the deep position. Specifically, Figure 1 and Figure 2 As shown, a first clamping portion is formed at the left end of the reed 2, and a second clamping portion is also formed at the left end inside the end cover 1, so that the leftmost end of the reed 2 can be clamped and fixed with the end cover 1 to achieve a deep connection.

[0058] And / or, at least one of the first clamping parts and one of the second clamping parts are clamped and matched with the end cover 1 at the side of the spring 2. That is, after the spring 2 is inserted into the end cover 1, the first clamping part and the second clamping part can be clamped and matched at the side of the spring 2, so that the spring 2 and the end cover 1 are clamped at the side position.

[0059] Among them, the end and side of the reed 2 can be clamped with the end cover 1 to achieve clamping cooperation with the end cover 1 at different depths from the end of the reed 2 to its side, thereby improving the clamping strength, enriching the clamping methods, and enhancing the clamping stability.

[0060] In some embodiments, the rubber strip insertion cavity 3 has a rubber strip insertion port 31, which is constructed to be open along the length direction of the reed 2, and the end of the reed 2 is suitable for being inserted into the rubber strip insertion cavity 3 from the rubber strip insertion port 31 along the length direction of the reed 2.

[0061] Specifically, Figure 2 As shown, the length direction of the reed 2 is Figure 2 In the left and right directions, the spring sheet 2, after being plugged into and matched with the end cover 1, jointly defines a rubber strip plug-in cavity 3 which is open to the right, that is, the rubber strip plug-in cavity 3 is formed with an open rubber strip plug-in port 31, so that the rubber strip 4 can be plugged into the rubber strip plug-in cavity 3 from the rubber strip plug-in port 31.

[0062] As well as Figure 1 As shown, the rubber strip plug-in interface 31 is formed on the right side of the rubber strip plug-in cavity 3, and the end of the rubber strip 4 can be plugged into the rubber strip plug-in cavity 3 from the rubber strip plug-in interface 31, and the rubber strip plug-in cavity 3 can limit the position of the rubber strip 4, so that the rubber strip 4 is relatively fixed to the reed 2 and the end cover 1, so that during the scraping process of the boneless wiper 100, the rubber strip 4 maintains a stable state, and when the rubber strip 4 has been used for a long time and structural damage occurs, the end of the rubber strip 4 can be pulled out of the rubber strip plug-in cavity 3 through the rubber strip plug-in interface 31, that is, the rubber strip 4 can be removed from the end cover assembly alone. Therefore, there is no need to replace the end cover assembly and the rubber strip 4 as a whole, and there is no need to disassemble the entire boneless wiper 100, which greatly reduces the difficulty of replacing the rubber strip 4 and reduces the cost of using the rubber strip 4.

[0063] In some embodiments, there are two reeds 2, which are spaced apart and respectively plugged into the end cover 1. The two reeds 2 and the end cover 1 together define a rubber strip plug-in cavity 3. In other words, the end cover 1 can be snap-fitted with the two reeds 2 at the same time, and after the two reeds 2 are snap-fitted and fixed to the end cover 1, the space between the two reeds 2 and part of the space between the reeds 2 and the end cover 1 together form a rubber strip plug-in cavity 3.

[0064] Therefore, when the rubber strip 4 is inserted into the end cover assembly, the rubber strip 4 can slide in the space defined by the two reeds 2 and the end cover 1, so that the rubber strip 4 can be fixedly inserted between the two reeds 2 and the end cover 1, or can be pulled out from between the two reeds 2 and the end cover 1. It should be noted that the rubber strip 4 can be constructed to have an I-shaped cross section, and the middle part of the I-shaped cross section can be slidably inserted between the two reeds 2, and the two ends of the I-shaped cross section can be respectively located on both sides of the reed 2, thereby achieving installation and matching of the rubber strip 4 with the end cover 1 and the reed 2.

[0065] Among them, after the rubber strip 4 is inserted into the end cover assembly, the reed 2 and the end cover 1 are matched with the upper limit position along the insertion direction of the rubber strip 4, so that when the rubber strip 4 is disassembled relative to the end cover assembly, the reed 2 and the end cover 1 will not be relatively separated, that is, the structural stability of the reed 2 is guaranteed, thereby solving the problem of structural damage to the end cover assembly caused by repeated disassembly of the reed 2 relative to the end cover 1, thereby improving the structural safety of the end cover assembly.

[0066] In some embodiments, the reed 2 has an inner side edge 21 and an outer side edge 22, the inner side edge 21 is located on the side of the reed 2 close to the rubber strip insertion cavity 3, and the outer side edge 22 is located on the side of the reed 2 away from the rubber strip insertion cavity 3. It can be understood that the rubber strip insertion cavity 3 is located between the two reeds 2, that is, the sides of the two reeds 2 close to each other are both the inner side edge 21, and the sides of the two reeds 2 away from each other are both the outer side edge 22.

[0067] Among them, the inner side edge 21 and / or the outer side edge 22 are clamped and limited with the end cover 1 through the first clamping part and the second clamping part, that is, the spring piece 2 can be clamped and matched with the end cover 1 through the first clamping part and the second clamping part at the inner side edge 21, and can also be clamped and matched with the end cover 1 through the first clamping part and the second clamping part at the outer side edge 22, or both the inner side edge 21 and the outer side edge 22 are clamped and matched with the end cover 1. Therefore, both spring pieces 2 can be clamped with the end cover 1 on the inside, or can also be clamped with the end cover 1 on the outside, and the clamping setting mode is flexible and optional, which is conducive to realizing different forms of clamping settings and improving the flexibility and multiple choices of the clamping form.

[0068] In some embodiments, the inner side edge 21 is provided with a first inner clamping portion 231, and the end cover 1 is provided with a second inner clamping portion 131 that is clamped and matched with the first inner clamping portion 231, that is, the spring leaf 2 can be provided with a first inner clamping portion 231 on the inner side, and a second inner clamping portion 131 that is matched with the clamping portion is provided on the end cover 1, so that the first inner clamping portion 231 and the second inner clamping portion 131 can be used to clamp and limit, so that the inner side of the spring leaf 2 can be clamped and matched with the end cover 1.

[0069] Specifically, Figure 2 As shown, the two spring leaves 2 are provided with a first inner clamping portion 231 on one side close to the rubber strip insertion cavity 3. At the same time, two second inner clamping portions 131 are provided on the inner end of the end cover 1. The second inner clamping portions 131 extend along the insertion direction of the rubber strip 4 and extend to a position where they are clamped and fixed with the first inner clamping portions 231.

[0070] And / or, the outer side 22 is provided with a first outer clamping portion 232, and the end cover 1 is provided with a second outer clamping portion 132 that is clamped and matched with the first outer clamping portion 232. That is, the spring leaf 2 can be provided with a first outer clamping portion 232 on the outer side, and the end cover 1 is provided with a second outer clamping portion 132 that is matched with the clamping portion, so that the first outer clamping portion 232 and the second outer clamping portion 132 can be clamped and limited, so that the outer side of the spring leaf 2 can be clamped and matched with the end cover 1.

[0071] Specifically, Figure 5 As shown, the two springs 2 are provided with a first outer clamping portion 232 on the side away from the rubber strip insertion cavity 3. Figure 4 As shown, two second outer clamping parts 132 are arranged on two opposite sides of the end cover 1. The second outer clamping parts 132 protrude in a direction perpendicular to the insertion direction of the rubber strip 4 and extend to a position where they are clamped and matched with the first outer clamping parts 232 for clamping and fixing.

[0072] In this way, the spring leaf 2 and the end cover 1 can be snap-fitted at two different positions, and through the cooperation of the first inner snap-fitting portion 231 and the second inner snap-fitting portion 131, and the first outer snap-fitting portion 232 and the second outer snap-fitting portion 132, a two-stage anti-slip structure can be formed in the direction of insertion of the spring leaf 2 and the end cover 1, thereby improving the reliability of the snap-fitting limit.

[0073] In some embodiments, both reeds 2 are provided with a second clamping portion, and the second clamping portions of the two reeds 2 are symmetrically distributed, that is, when the two reeds 2 are respectively clamped with the end cover 1, they can form two groups of symmetrically distributed clamping fitting structures with the end cover 1, thereby making the clamping force between the two reeds 2 and the end cover 1 relatively uniform.

[0074] Therefore, after the two spring leaves 2 are snap-fitted with the end cover 1, during the process of inserting or removing the rubber strip 4 into or from the rubber strip insertion cavity 3, the two spring leaves 2 can maintain a stable snap-fit ​​state with the end cover 1, that is, the two spring leaves 2 will not be subjected to uneven force, resulting in the overall tilting and structural damage, thereby improving the safety of the structural setting.

[0075] In some embodiments, one of the first clamping portion and the second clamping portion includes a clamping groove 233 and the other includes a clamping protrusion 133, and the clamping protrusion 133 is clamped in the clamping groove 233, that is, the first clamping portion is constructed as the clamping groove 233, and the second clamping portion is constructed as the clamping protrusion 133, or the first clamping portion is constructed as the clamping protrusion 133, and the second clamping portion is constructed as the clamping groove 233, both of which can achieve a clamping fit between the two.

[0076] Specifically, Figure 4As shown, the first clamping portion is constructed as a clamping protrusion 133, and the first clamping portion is provided in two groups, one group of clamping protrusions 133 is provided at the left end of the end cover 1, and the other group of two clamping protrusions 133 are respectively provided at two opposite sides of the end cover 1. Figure 5 As shown, the second clamping portion is configured as a clamping groove 233 , and two clamping grooves 233 are provided, one clamping groove 233 is provided at the left end of the reed 2 , and the other clamping groove 233 is provided at the outer side 22 of the reed 2 .

[0077] Therefore, when the spring leaf 2 is snap-fitted with the end cover 1 , the snap-fitting protrusion 133 can be pressed against the inner wall of the snap-fitting groove 233 , thereby forming a snap-fitting and limiting fit.

[0078] In a further embodiment, one of the first clamping portion and the second clamping portion further includes a limiting protrusion 234, at least a portion of which is constructed as an inner wall of the clamping groove 233, and the clamping protrusion 133 is pressed against the clamping protrusion 133, whereby, when the clamping protrusion 133 is clamped with the clamping groove 233, the clamping protrusion 133 stops against the limiting protrusion 234, so as to form a limiting fit through the pressure between the clamping protrusion 133 and the limiting protrusion 234.

[0079] Specifically, Figure 5 As shown, the second clamping portion is configured as a clamping groove 233, and the second clamping portion further includes a limiting protrusion 234, and the surface of the limiting protrusion 234 facing the clamping groove 233 is configured as a limiting surface, which can limit and press the clamping protrusion 133. In this way, the clamping cooperation between the spring leaf 2 and the end cover 1 can be achieved, and the clamping stability can be ensured.

[0080] In some embodiments, the end cover 1 includes a top plate 11 and a bottom plate 12, the top plate 11 is spaced apart from the bottom plate 12 and a plug-in space is formed, and the spring 2 is suitable for being inserted into the end cover 1 along the plug-in space, wherein the top plate 11 and the bottom plate 12 can be arranged to be spaced apart and distributed along the thickness direction of the end cover 1 so that the spring 2 can be plugged in between the top plate 11 and the bottom plate 12, that is, the spring 2 can slide into the plug-in space along the top plate 11 and the bottom plate 12, and after being inserted to the target depth, the first clamping portion is clamped and fixed with the second clamping portion.

[0081] Therefore, when the spring leaf 2 is installed and matched with the end cover 1, it can not only be clamped and limited by the first clamping part and the second clamping part, but also can be guided and slid in through the space between the top plate 11 and the bottom plate 12, that is, the top plate 11 and the bottom plate 12 can limit the spring leaf 2 along the thickness direction of the end cover 1, so that the spring leaf 2 and the end cover 1 can be limited in the insertion direction and can also be limited in the thickness direction, thereby helping to improve the assembly stability of the two.

[0082] Furthermore, in some embodiments, at least one first clamping portion is provided in the plug-in space, and the spring leaf 2 is provided with at least one second clamping portion for clamping and matching with the first clamping portion in the plug-in space, so that the spring leaf 2 and the end cover 1 can be both plugged and matched in the plug-in space, thereby realizing compact installation of the spring leaf 2 and the end cover 1, and by limiting the spring leaf 2 by the top plate 11 and the bottom plate 12, the problem of clamping failure of the first clamping portion and the second clamping portion in the plug-in space can be avoided, and the structure is more stable.

[0083] The present invention also provides a frameless wiper 100 .

[0084] The frameless wiper 100 according to the embodiment of the present invention comprises an end cap assembly of the frameless wiper of any of the above embodiments. Figure 6 and Figure 7 As shown, the boneless wiper 100 further includes a wiper bracket 5, an anti-floating wing 6 and a rubber strip 4, wherein the wiper bracket 5 is connected to an accessory 51 and can be connected to the vehicle body, there are two anti-floating wings 6, and the two anti-floating wings 6 are connected to the two ends of the wiper bracket 5, and the two springs 2 are distributed in parallel and are both connected to the two anti-floating wings 6. There are two end caps 1, and the two end caps 1 can be connected to the two ends of the spring 2 respectively, and the two ends of the rubber strip 4 are respectively plugged into the rubber strip plug-in cavities 3 corresponding to the two end caps 1.

[0085] Therefore, during actual installation, the two ends of the spring 2 can be respectively snap-fitted with the two end covers 1, so that the spring 2 and the two end covers 1 are connected to form a whole, and then the two ends of the rubber strip 4 can be respectively inserted into the two rubber strip insertion cavities 3, and the two ends of the rubber strip 4 can also be respectively pulled out from the two rubber strip insertion cavities 3. The structure is simple, and the installation and disassembly of the rubber strip 4 are more convenient. In the process of inserting or pulling out the rubber strip 4, there is no need to repeatedly disassemble and assemble the snap-fitting position of the spring 2 and the end cover 1, which can reduce the damage to the matching structure between the spring 2 and the end cover 1 during the disassembly and assembly of the rubber strip 4, thereby improving the safety of the end cover assembly.
