Description

Technical Field

[0001] The present invention relates to the field of boneless wipers, and in particular to an outsourced end buckle for a boneless wiper and a boneless wiper made using the end buckle. The boneless wiper is specifically equipped with a spoiler, which can produce relative displacement along the length direction relative to the bearing component. One of the technical functions of the end buckle is to limit the displacement of the spoiler along its length direction toward the end buckle. Background Art

[0002] There are different types of frameless wipers on the market. Figure 1 The boneless wiper disclosed in CN107444347A is equipped with a spoiler 9' for reducing wind resistance, and an end buckle 18' is respectively arranged at both ends of the rigid element, also known as a spring or elastic supporting component, of the boneless wiper 1'. The end buckle 18' at least achieves the limitation of the spoiler 9' and the wiper rubber strip 10' along the length direction. However, with the end buckle 18' of this structure, it is difficult for consumers to detach it from the rigid element, so that consumers never consider replacing the spoiler 9' based on long-term usage habits. As a result, if the spoiler 9' is damaged or a spoiler with a different guide part shape is required based on the personalized needs of consumers, the only way is to replace it with a new wiper. In fact, it is not conducive to the design trend of energy conservation and emission reduction, and cannot meet the consumer's demand for personalized products.

[0003] In view of this, the inventors conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Summary of the Invention

[0004] A first object of the present invention is to provide an end buckle for easily replacing a spoiler.

[0005] A second object of the present invention is to provide an end buckle that is easy to replace the spoiler and the wiper strip.

[0006] The third object of the present invention is to provide a boneless wiper equipped with the above-mentioned end buckle.

[0007] A fourth object of the present invention is to provide a boneless wiper, the spoiler of which can have different color schemes for consumers to make personalized choices.

[0008] To achieve the first objective of the present invention, the present invention discloses an end clip for a boneless wiper, comprising a cover and a base. The base has an inner cavity configured with at least a first channel, the first channel being configured to receive and secure an end portion 81 of an elastic support member. A connecting assembly is configured between the cover and the base, enabling the cover and the base to switch between an open state and a closed state. When the cover and the base are in a closed state, the cover is placed on the base and stably connected thereto, so that the cover constitutes an obstacle to the displacement of the spoiler 7 in its direction; When the cover and the base are in an open state, the cover is moved away from above the base, so that the spoiler can be pulled away from above the base.

[0009] By adopting the above structure, the present invention abandons the end buckle structure used in the conventional field of boneless wipers, that is, the cover cover and the base body adopt an integrally formed and fixed structure, but the present invention uses a connecting component to realize the switching of the cover cover and the base body between the open state and the closed state, overcoming the technical prejudice formed for a long time by this structure, thereby making it very convenient for users to replace the spoiler.

[0010] In order to achieve the second purpose of the present invention, the present invention discloses that the inner cavity of the seat body of the end buckle is also provided with a second channel for receiving the rubber strip base of the wiper strip below the first channel, and the second channel is formed by a pair of longitudinal hooks arranged opposite to each other along the length direction, the hook portion of the longitudinal hook forms a gap, one end of the longitudinal hook forms an insertion end for inserting the rubber strip base, and a blocking surface for limiting the rubber strip base is constructed on the side of the longitudinal hook away from the insertion end; the hook portion of the two longitudinal hooks forms a flared portion for pulling out / inserting the wiper strip.

[0011] With the above structure, by adding a flared portion to the hook portion of the longitudinal hook of the seat body, it is convenient for users to replace the wiper rubber strips.

[0012] Furthermore, the flared portion is provided on a side adjacent to the insertion end, and a length L1 from the blocking surface to the access end of the flared portion is [10 mm 30 mm].

[0013] The above arrangement can prevent the end of the wiper strip base facing the end buckle from accidentally popping out of the flared portion when the wiper strip is wiping, causing the wiper strip to accidentally separate from the wiper.

[0014] In order to achieve the third purpose of the present invention, the present invention discloses a boneless wiper, which at least includes a spoiler, an elastic support component, a bearing component and a wiper strip. The bearing component is assembled with the spoiler, the elastic support component and the wiper strip in sequence from top to bottom. The spoiler can be displaced along the length direction relative to the bearing component, and it is also configured with any of the end buckles mentioned above.

[0015] With the above structure, the boneless wiper can at least realize the rapid replacement of the spoiler. When the end buckle is configured with a flared portion on the hook portion of the longitudinal hook, the wiper rubber strip can also be quickly replaced.

[0016] To achieve the fourth purpose of the present invention, the spoiler of the boneless wiper disclosed in the present invention can be configured with colors to meet the personalized needs of users. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The directions of “front” and “rear” in the present invention are consistent with the directions marked in the accompanying drawings in the specification.

[0020] The term "lateral" as used in relation to "lateral track" refers to a direction parallel to the length of the seat.

[0021] like Figures 2 to 3a The present invention discloses a boneless wiper, which includes a wiper joint assembly 30, a spoiler 7, an elastic support component 8, a bearing component 10, a wiper rubber strip 9 and end buckles 100a, 100b, 100c. The wiper joint assembly 30 disclosed in this embodiment includes a joint base 301 and a wiper arm connecting portion 302. The wiper arm connecting portion 302 is used to achieve connection with the corresponding wiper arm. The joint base 301 is used to penetrate the elastic support component 8, and the joint base 30 and the elastic support component 8 form a necessary limit fitting portion for limiting The displacement of the elastic support component 8 relative to the joint base 11 along the length direction forms a necessary connection and matching structure between the scraper arm connection part 302 and the joint base 301. The connection and matching structure can refer to the connection structure disclosed in CN116985752A, but this is not the only one. Ordinary technicians in this field can develop a variety of connection structures that can realize the detachable and matching of the scraper arm connection part 302 and the joint base 301. At the same time, in fact, the present invention does not exclude the solution of the joint base 301 and the scraper arm connection part 302 being integrally formed. Figure 3b The bearing member 10 is arranged on both sides of the wiper connector assembly 30, and is configured with a mounting portion 101, a third channel 102 and a fourth channel 103 from top to bottom. The mounting portion 101 is used to be nested with the matching portion 71 at the bottom of the spoiler 7. Figure 5f, so that the matching portion 71 of the spoiler 7 can be relatively displaced along its length direction relative to the mounting portion 101 of the bearing component 10, the third channel 102 is used to receive the elastic support element 8, and a longitudinal opening is formed at the bottom of the fourth channel 103, which is used to receive the wiper rubber strip 9. The structure of the bearing component 10 disclosed in this embodiment can also refer to the following patent documents such as CN103269920A, CN103619666A and CN103619668A, that is, the spoiler 7 is assembled through the bearing component 10 is a prior art, and the structural innovation of the subsequent end buckle of the present invention depends on this environmental feature; it should be emphasized that the spoiler 7 of the boneless wiper disclosed in the present invention can be configured with color, that is, the user can choose spoilers 7 of different colors according to their personalized needs. Similarly, end buckles 100a, 100b, 100c are arranged at both ends of the elastic support component 8, and the end buckles 100a, 100b, 100c must be provided with a first channel 28, which is connected to the third channel 102 and is used to receive and fix the end 81 of the elastic support component 8. In most cases, the end buckles 100a, 100b, 100c are further provided with a second channel 29 for receiving the rubber strip base 91 of the wiper rubber strip 9 below the first channel 28. The second channel 29 is surrounded by a pair of longitudinal hooks 291 arranged opposite to each other along the length direction. The longitudinal hook 291 is basically "L-shaped", and a gap is formed between the two hooks 292. The gap, one end of the longitudinal hook 291 forms an insertion end for inserting the rubber strip base 91, and a blocking surface 294 for limiting the rubber strip base 91 is constructed on the side of the longitudinal hook 291 away from the insertion end. The definition of the rubber strip base 91 here is that a U-shaped groove is formed on both sides of the rubber strip base 91 for nesting and cooperating with the hook parts 292 of the two longitudinal hooks 291. The second channel 29 is docked with the fourth channel 103. It should be noted that the second channel 29 of the end buckle can be designed by default, and it is only necessary to extend the fourth channel 103 of the bearing component 10 to the bottom of the first channel 28, which is not shown in the figure, but this is a prior art, not the innovation of the case of the present invention, and will not be described in detail.

[0022] The following is an explanation of the innovative structure of the end buckle of the present invention: Embodiment 1: The cover 1a and the base 2a adopt a flip-cover structure.

[0023] like Figure 4 、 5a-5f, the end buckle 100a includes a covering cover 1a and a base 2a, a connecting component 22a is arranged between the covering cover 1a and the base 2a, the covering cover 1a includes a top wall 14 and two side walls 15 to form a covering body, the base 2a is provided with the aforementioned first channel 28 and second channel 29, of course, if explained above, the second channel 29 can be designed by default; the connecting component 22a includes a pivot connection part 221 and a limiting matching part 222, the number of the pivot connection part 221 and the limiting matching part 222 are two respectively, the pivot connection part 221 includes a pivot seat 2211 arranged at the rear end of the two side walls 15 of the covering cover 1a and a boss 2222 arranged at the rear end of both sides of the base 2a, the covering cover 1 The two pivot seats 2211 of a are rotatably inserted on the protruding column 2222, so that the covering cover 1a can be flipped clockwise or counterclockwise relative to the base 2a through a pivot connection part 221; the limiting matching part 222 is provided between the covering cover 1a and the base 2a and is located at the front end of the pivot connection part 221. The limiting matching part 222 specifically includes a card block 11 provided on the inner wall side of the two side walls 15 of the covering cover and a stop surface 21 provided on both sides of the base 2a. The card block 11 is provided with an upward card stop surface 111 and a card positioning inclined surface 12 facing the stop surface 21. When the covering cover 1a is closed along the pivot connection part 221 and the base 2a, the stop surfaces 21 on both sides are carded into the card block 11 along the two card positioning inclined surfaces 12, so that the stop surface 21 and the card positioning are fixed. The stop surfaces 111 of the blocks 11 engage with each other, and at this time the cover 1a and the seat body 2a are closed, thereby sealing the end of the spoiler 7 on the inner wall side of the cover 1a, thereby hindering the spoiler 7 from moving in its direction; a more preferred design is that a stop bar 141 is convexly provided on the inner wall side of the top wall 14 of the cover 1a, and the stop bar 141 is used to prevent the spoiler 7 from moving in its direction. It should be noted that the design of the stop bar 141 can be applicable to subsequent cover covers 1a, 1b, and 1c with different structural forms. When the user needs to replace the spoiler 7, he only needs to force the cover 1a to open upwards. Because the cover 1a is made of plastic and has a certain elastic deformation space, it can be rotated around the pivot connection part 221 to make the cover 1a and the seat body 2a exceeds a certain angle. Normally, the angle is preferably greater than 90 degrees. However, considering that the spoiler 7 is made of flexible material, if it is slightly lower than 90 degrees, theoretically, the spoiler 7 can also be removed from the supporting component 10. In short, when the cover 1a and the base 2a are in the open state, the angle between the two is preferably set to 100 degrees to 180 degrees. The larger the angle, the more conducive it is to replace the spoiler 7. In this embodiment, since the cover 1a is not provided with a rear wall at the rear ends of the two side walls 15, that is, the two side walls 15 form a hollow portion 19 relative to the pivotal portion 2211, the cover 1a can form a 180° angle with the base 2a, which can make it easier to remove the spoiler 7 from the mounting portion 101 of the supporting component 10 (such as Figure 4 shown).

[0024] More preferably, a design such as Figure 5a The top of the first channel 28 of the base body 2a is provided with an upper wall 281. A notch 282 is defined at the front end of the upper wall 281. The notch 282 is used to provide a clearance for the mating portion 71 of the spoiler 7. This facilitates the removal of the mating portion 71 of the spoiler 7 from the mounting portion 101 of the support member 10 when the cover 1a is opened relative to the base body 2a. The upper wall 281 of the first channel 28 does not interfere with the mating portion 71, thereby facilitating the removal of the spoiler 7 from the support member 10. It should be noted that this structural feature is also applicable to various embodiments described subsequently.

[0025] More preferably, Figures 5b-5f As shown, elastic cantilevers 23 can be respectively provided on both sides of the base 2a, and the stop surfaces 21 on both sides are respectively provided on the free ends of the two elastic cantilevers 23, and the elastic cantilevers 23 are convexly provided with a pressing portion 231, and the two side walls 15 of the covering cover 1a are respectively provided with hollow notches 13 at positions corresponding to the pressing portions 231. When the covering cover 1a is buckled onto the base 2a, the two side walls 15 of the covering cover 1a will not interfere with the pressing portions 231 of the elastic cantilevers 23, and the elastic cantilevers 23 are free to move. The stop surface 21 at the end is engaged with the stop surface 111 of the block 11 to achieve a stable connection between the cover 1a and the base 2a; when the spoiler 7 of the wiper needs to be replaced, it is only necessary to press the pressing parts 231 of the elastic cantilevers 23 on both sides inward with force to make the two elastic cantilevers 23 elastically deform inward, so that the stop surface 21 is retracted inward. At this time, the stop surface 21 and the stop surface 111 of the block 11 are misaligned with each other, so that the cover 1a can be flipped upward relative to the base 1a to open and the spoiler 7 can be removed.

[0026] Because in the embodiment, the covering cover 1a is based on the design requirement of inserting the spoiler 7, the inner contour of its top wall 14 is adapted to the outer contour of the air guide portion 72 of the spoiler 7, and the covering cover 1a has a separate extension section X extending out of the front end (insertion end) of the first channel 28 of the seat body 2a, that is, the top wall 14 and both side walls 15 of the covering cover 1a have an extension section X extending out of the front end of the seat body 2a, and the cavity configured by the extension section X can be used to accommodate the end of the spoiler 7 and the end of the supporting component 10 (referring to the structure in which the supporting component 10 is located above the fourth channel 103), which can cover the joint produced by the docking between the supporting component 10 and the seat body 2a, making the overall shape of the wiper simpler and enhancing the beauty of the product; at the same time, limiting the relative displacement of the supporting component 10 relative to the end buckle 100a along the width and height directions, further enhancing the stability of the boneless wiper in the connection area of ​​the end buckle.

[0027] Embodiment 2: A sliding cover structure is used between the cover 1b and the base 2b.

[0028] like Figures 6a-6i As shown, the end buckle 100b includes a covering cover 1b, a base 2b and a connecting component 22b, and the connecting component 22b includes a sliding fitting portion 223 and a limit stop portion 224; the sliding fitting portion 223 is used to realize that the covering cover 1b can only be displaced relative to the base 2b along its length direction, and more specifically, the sliding fitting portion 223 includes a transverse rail 24 and a sliding member 17, and the transverse rail 24 is arranged on both sides of the base 2b, and the inner wall side of the covering cover 1b is fixedly connected to the sliding member 17 at a position relative to the transverse rail 24, and the sliding member 17 can slide back and forth along its length direction within the space defined by the transverse rail 24; in each of the embodiments, the transverse rail 24 can be arranged at the upper, middle or lower part of both sides of the base 2b, and the sliding members 17 on the inner wall side of both sides of the covering cover 1b are respectively designed at corresponding positions; as shown Figure 6a 、 6d As shown in FIG6e, the transverse rails 24 are provided on both sides of the upper portion of the seat body 2b; Figure 6b and Figure 6f As shown, the transverse rails 24 are provided at the middle of both sides of the seat body 2b; Figure 6c As shown, the transverse rails 24 are provided at the lower portions of both sides of the seat body 2b; Figures 6a-6c In the embodiment of the present invention, the cover 1b includes a top wall 14, two side walls 15 and a rear wall 110, which together form a cavity with an opening facing downward and toward the front end. The base 2b is covered by the cavity of the cover 1b. Sliders 17 are provided at corresponding positions of the two side walls 15 of the cover 1b to achieve sliding cooperation with the transverse track 24 of the base 2b. In other embodiments, the cover 1b can also be designed as a flat cover, such as in Figure 6d As shown in , the cover 1b basically eliminates the design of the two side walls, and only retains the design of the top wall 14 and the rear wall (shorter in height). By arranging the sliding members 17 on both sides of the inner wall side of the top wall 14 and arranging matching transverse rails 24 on both sides above the first channel 28 of the base 2b, the sliding fit between the cover 1b and the base 2b is achieved; or as shown in Figure 6e The disclosed cover 1b shortens the height of the two side walls 14 and the rear wall 110. By setting a sliding member 17 on the inner wall side of the two side walls and setting a matching transverse track 24 on both sides above the first channel 28 of the base 2b, the sliding fit between the cover 1b and the base 2b can also be achieved. The above-mentioned different forms of design are only suitable for different forms of use occasions, and the inventive concept is basically the same. At the same time, it should be emphasized that the present invention does not emphasize that the sliding member 17 can only be set on the cover 1b, and the transverse track 24 can only be set on the base 2b. In fact, replacing them with each other can also meet the use requirements. It should be noted that Figure 6d and Figure 6eSince the disclosed covering hood 2b is a design scheme with no side walls or short side walls, the top wall 14 of the covering hood 1b together with the two side edges of the base body 2b will form an extension section X toward the front end of the second channel 28 of the base body 2b. The extension section X of the covering hood 1b and the extension sections X on the two side edges of the base body 2b jointly enclose a cavity for accommodating the spoiler 7 and the supporting component 10. The technical effects produced are as described above and will not be repeated here.

[0029] The limit stop portion 224 includes a front limit portion 2241 and a rear limit portion 2242; Figures 6a to 6e , which discloses a form of front limit portion 2241, including a stopper 26 arranged at the front end of the transverse rail 24 and a slot 18 arranged on the sliding member 17, the stopper 26 forms a first limit surface 261 toward the front end, and the slot 18 forms a second limit surface 181 relative to the first limit surface 261, and the front limit portion 2241 is triggered to take effect by the mutual engagement of the first limit surface 261 and the second limit surface 181. Preferably, in order to facilitate the front end of the sliding member 17 to pass over the stopper 26, mutually matching guide inclined surfaces can be configured at the front end of the sliding member 17 and the rear end of the stopper 26 to facilitate the front end of the sliding member 17 to pass over the stopper 26, so that the stopper 26 is built into the slot 18 of the sliding member 17; of course, the front limit portion 2241 is not limited to this structural form, such as Figures 6f-6i As shown, the front limiting portion 2241 can be formed by providing a second elastic cantilever 16 arranged along the length direction on the top wall 14 of the covering cover 1b, and a blocking member 161 is protruded downward at the free end of the second elastic cantilever 16. The blocking member 161 is provided with at least one third limiting surface 162 toward the rear end, and the seat body 2b is provided with a limiting hole 27 at a position relative to the blocking member 161. The limiting hole 27 forms a fourth limiting surface 271 on the third limiting surface 162. The mutual engagement of the limiting surface 162 and the fourth limiting surface 271 triggers the front limiting portion 2241 to take effect. When it is necessary to disable the front limiting portion 2241, it is only necessary to apply a thrust from the front to the rear to the covering cover 1b so that the positions of the two relative limiting surfaces are staggered (because the plastic parts have a certain space for elastic deformation), thereby disabling the front limiting portion 2241. In short, the front limiting portion 2241 can realize the limitation of the covering cover 1b from the front to the rear relative to the base body 2b along the length direction.

[0030] The rear limiting portion 2242 is triggered to take effect by adding a rear wall 110 at the rear end of the covering hood 1b, through the interference between the rear wall 110 and the rear end surface 201 of the seat body 2b. The rear limiting portion 2242 is used to achieve the limitation of the covering hood 1b from the rear to the front relative to the seat body 2b along the length direction.

[0031] In short, when the covering cover 1b slides from back to front to the specified position relative to the base body 2b, that is, the rear wall 110 of the covering cover 1b is against the rear end face 210 of the base body 2b, the front limit part 2241 and the rear limit part 2242 take effect at the same time. At this time, when the covering cover 1b and the base body 2b are in a closed state, the covering cover 1b constitutes an obstacle to the displacement of the spoiler 7 in its direction; when the covering cover 1b needs to be slid from front to back relative to the base body 2b, the covering cover 1b needs to overcome the constraint of the front limit part 2241, so that the rear wall 110 of the covering cover 1b is away from the rear end face 210 of the base body 2b. At this time, when the covering cover 1b and the base body 2b are in an open state, the covering cover 1b does not constitute an obstacle to the displacement of the spoiler 7 in its direction, so that the spoiler 7 can be pulled out from above the base body 2b.

[0032] Embodiment 3: The flip cover 1c and the base body 2c adopt a plug-in structure.

[0033] like Figure 7a 、 7b As shown, the connecting component 22c is composed of a plug-in fitting part, and the plug-in fitting part 22c includes plug blocks 3 arranged on both sides of the cover 1c and slots 4 arranged at corresponding positions of the base 2c. The cover 1c is designed as a flat cover or an embedded cover mode, which is placed above the base 2c. The bottom of the two sides of the cover 1c are respectively protruding outward with plug blocks 3. This embodiment discloses that two plug blocks 3 are arranged at intervals along the length direction at the bottom of each side wall of the cover 1c. The plug blocks 3 are designed to be raised at the end to form a fifth limiting surface 31, and an inclined guide surface 32 is provided at the bottom of the plug block 3; the two side edges of the base 2c extend inwardly in the upper direction of the first channel 28 to form two oppositely arranged bending sections 25, and a slot 4 is provided on the inner end surface of the bending section 25 and relative to the position of the plug block 3. A corresponding sixth limiting surface 41 is provided in the slot 4, and the cover 1c The base 2c is tightly covered downwards, and the inclined guide surface 32 of each insert 3 slides into the slot 4 until the fifth limiting surface 31 is just stuck under the sixth limiting surface 41, so that the cover 1c and the base 2c are fixedly plugged in up and down; when it is necessary to unlock the cover 1c and the base, it is only necessary to pull up the cover 1c. Based on the elasticity of the cover 1c, the fifth limiting surface 31 of the insert 3 naturally leaves the sixth limiting surface 41 of the slot 4, thereby realizing the separation of the cover 1c from the base. like Figure 7c 、 7dAs shown, this embodiment provides another plug-in mating structure for the cover 1c and the base 2c. The inventive concept is essentially the same as the aforementioned one, except that the cover 1c completely encloses both sides of the base 2c. Therefore, the location of the insert block 3 is moved to the inner side of the cover 1c's side walls, and the slot 4 is moved to the sides of the base, opposite the insert block 3. Similarly, the insert block 3 is provided with an upwardly raised fifth limiting surface 31, and the bottom of the insert block 3 is provided with an inclined guide surface 32. Similarly, the lower portion of the slot 4 is provided with an inwardly recessed sixth limiting surface 41. When the cover 1c is tightly closed over the base 2c, the inclined guide surface 32 of each insert block 3 slides along the slot 4 until the fifth limiting surface 31 fits neatly under the sixth limiting surface 41, thereby achieving a vertically fixed connection between the cover 1c and the base 2c. When it is necessary to unlock the cover 1c and the base 2c, the cover 1c can be separated from the base 2c by simply pulling up the cover 1c.

[0034] In short, when the insert block 3 of the covering cover 1c is inserted into the slot 4 of the base body 2c from top to bottom, and the covering cover 1c and the base body 2c are in a closed state, the covering cover 1c constitutes an obstacle to the displacement of the spoiler 7 in its direction; when the insert block 3 of the covering cover 1c is removed from the slot 4 of the base body 2c from bottom to top, and the covering cover 1c and the base body 2c are in an open state, the covering cover 1c does not constitute an obstacle to the displacement of the spoiler 7 in its direction, so that the spoiler 7 can be pulled out from above the base body 2c.

[0035] In addition, the present invention also discloses a boneless wiper, the end buckle of which is equipped with a structure that can realize the convenient replacement of the spoiler 7 as described above, and can also quickly replace the wiper rubber strip. Of course, the premise for meeting this technical effect is that the end buckle must be equipped with a second channel 29, and the second channel 29 is surrounded by a pair of longitudinal hooks 291 arranged oppositely along the length direction. The hook portion 292 of the longitudinal hook 291 forms a gap. Taking the end buckle 100a as an example, Figure 5e The hook portion 292 of the two longitudinal hooks 291 forms a flared portion 293 for pulling out / inserting the wiper strip 9. When the wiper strip 9 needs to be replaced, just hold the scraping edge portion 92 of the wiper strip 9 with your hand, and pull out the strip base 91 of the wiper strip 9 placed in the second channel 29 of the end buckle 100a from the flared portion 293, and then pull out the strip base 91 placed in the fourth channel 103 of the bearing component 10 to complete the removal of the old wiper strip 9, and then insert the strip base 91 of the new wiper strip 9 through the flared portion 293 and place it in the fourth channel 103 of the bearing component 10, and finally insert it into the second channel 29 of the end buckle 100a to complete the replacement of the new wiper strip 9.

[0036] In a more preferred design, the flared portion 293 is arranged on a side adjacent to the insertion end, and the length L1 from the blocking surface 294 to the access end of the flared portion 293 is [10mm 30mm]. This can prevent the end of the wiper strip 9 facing the end buckle from accidentally popping out from the flared portion 293 when the wiper strip 9 is wiping, causing the wiper strip 9 to accidentally separate from the wiper.

[0037] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
