Description

Technical Field

[0001] The present invention relates to the field of windshield wipers, in particular to a series bearing component for fixing an elastic supporting component and a windshield wiper rubber strip, and a windshield wiper equipped with the bearing component. Background Art

[0002] The conventional boneless wiper has an intermediate bearing member configured to connect the elastic supporting member with the intermediate bearing member, as disclosed in the patent document CN1984803A. Figure 1-1 The bearing component 20a is provided with a first mounting groove 22a and a second mounting groove 24a from top to bottom. The first mounting groove 22a is used to insert the elastic supporting component 30a, and the second mounting groove 24a is used to insert the wiper rubber strip 40a. However, this type of bearing component 20a is generally made of extruded plastic material, and in order to adapt to the pre-bent curvature of the elastic supporting component 30a, if the bearing component 30a is extruded using hard plastic polypropylene (PP), even if the first mounting groove 22a and the second mounting groove 24a are respectively formed with openings, the flexibility of the bearing component may not be able to adapt to extreme climate environments, such as extremely cold weather. Therefore, the industry has made improvements based on it, referring to the patent document disclosed in CN104228774A, such as Figure 1-2 , a plurality of notches 50b are provided in the first mounting groove 12b and / or the second mounting groove 13b on the bearing member 10b (the original patent document is the seat body, which is equivalent to the bearing member of the present invention) at intervals along the length direction to solve the problem of the flexibility of the bearing member 10b. However, this structure has higher requirements on the processing equipment and processing accuracy, and the production cost is higher. At the same time, according to the patent document disclosed in CN101456407A, such as Figure 1-3 , it replaces the original integrated load-bearing components with several staggered receiving blocks 30 and counterweight blocks 40. However, since this structure adopts no connecting components between the receiving blocks 30 and the counterweight blocks 40, they are only connected in series between the support seat 20 and the edge sealing cover 80 through the elastic support component 10. The total length of the receiving blocks 30 and the counterweight blocks 40 will not exactly match the accommodation length between the support seat 20 and the edge sealing cover 80, that is, one or more receiving blocks 30 located on one side of the support seat 20 and the counterweight blocks 40 adjacent to them will have relative displacement along the length direction of the elastic support component 10. At the same time, the configuration block 40 is not configured with a horizontal clamping portion 391 for supporting the wiper strip 50, and is only set on the receiving block 30. The above factors will affect the force points of the wiper strip 50 along the length direction, resulting in uneven force, which ultimately affects the cleanliness of the wiper strip 50.

[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] The first object of the present invention is to provide a load-bearing component that can be conveniently connected in series, and the angle α between two adjacent load-bearing components can be adaptively adjusted according to the curvature of the elastic support component.

[0005] The second object of the present invention is to provide a bearing component capable of carrying a spoiler on the basis of satisfying the first object of the present invention.

[0006] The third object of the present invention is to provide a bearing component of an integrally formed guide portion on the basis of satisfying the first object of the present invention.

[0007] The fourth object of the present invention is to provide a frameless wiper equipped with the above-mentioned bearing component.

[0008] A fifth object of the present invention is to provide a boneless wiper with an easy-to-replace spoiler.

[0009] The sixth object of the present invention is to provide a boneless wiper having a spoiler with a configured color under the premise of satisfying the fifth object of the present invention.

[0010] The seventh object of the present invention is to provide a boneless wiper with easy replacement of wiper rubber strips.

[0011] To achieve the first objective of the present invention, the present invention discloses a serial bearing component, which serves as an intermediate connecting component between an elastic supporting component and a wiper rubber strip, and includes a first bearing component, a second bearing component, and an Nth bearing component arranged in sequence along the X-axis direction, where N is a positive integer greater than 2; Each of the bearing components is made of hard plastic material and is provided with a first accommodating groove and a first clamping groove in sequence from top to bottom; The first receiving groove of each of the supporting components includes a bottom wall, two side walls, and a top wall, wherein the two side walls are connected by the bottom wall and / or the top wall as transverse connecting members to form the first receiving groove as an integral component; the first receiving groove is configured with at least one first receiving channel for allowing the elastic support component to pass through, and the first receiving channel is used to limit the relative displacement of the elastic support component relative to the supporting component in the height and width directions; A first clamping groove for inserting the wiper rubber strip is formed below the bottom wall, the first clamping groove constructs a clamping space for clamping the wiper rubber strip, and at least the first clamping grooves of adjacent bearing components are spliced ​​with each other; A first connecting portion and a second connecting portion are respectively provided at the front end and the rear end of each of the supporting components. By connecting the corresponding first connecting portion and the second connecting portion to each other, the two adjacent supporting components can be restricted from separating from each other along the X-axis direction, and the angle α between the two adjacent supporting components can be adaptively adjusted according to the bending curvature of the elastic support component.

[0012] With the above structure, first, the load-bearing components are made of hard materials, which have a longer service life compared to traditional soft material load-bearing components. Moreover, since each load-bearing component is independent of each other, they are connected to each other along the length direction (X-axis direction) through the first connecting part and the second connecting part, so that each load-bearing component can be connected in series with each other along the length direction to construct a load-bearing component assembly with a certain length. At the same time, since the length of each load-bearing component is limited, the angle α between two adjacent load-bearing components can be adaptively adjusted according to the bending curvature of the elastic support component, so as to better match the rapid change of the bending curvature of the elastic support component (when the wiper is wiping, the surface curvature of the windshield changes, and the bending curvature of its elastic support component always changes within a certain range).

[0013] In order to achieve the second purpose of the present invention, the present invention discloses that each of the supporting components is also provided with a mounting portion for assembling the spoiler, and the mounting portion is provided with a second accommodating channel for the mating portion of the spoiler to pass through, and the inner contour of the second accommodating channel matches the outer contour of the mating portion of the spoiler.

[0014] In order to achieve the third object of the present invention, each of the supporting components disclosed in the present invention is further integrally formed with a guide portion.

[0015] To achieve the fourth objective of the present invention, the present invention discloses a boneless wiper, wherein the intermediate bearing component for connecting the elastic supporting component and the wiper rubber strip is composed of a plurality of bearing components described in any one of the aforementioned items.

[0016] In order to achieve the fifth purpose of the present invention, the present invention discloses that when the mounting portion of the bearing component is arranged above the first accommodating channel, the end buckle is composed of a covering cover and a seat body, and the covering cover and the seat body can be switched between an open state and a closed state, wherein the fourth accommodating channel and the third clamping groove are arranged on the seat body, when the covering cover is in an open state, the spoiler can be pulled outward from the spoiler accommodating cavity without interfering with the covering cover, and when the covering cover is in a closed state, the spoiler will be constrained in the spoiler accommodating cavity set by the covering cover, thereby limiting the spoiler from being pulled outward.

[0017] In order to achieve the sixth purpose of the present invention, the boneless wiper is provided with an end buckle for quickly replacing the spoiler, and the guide portion of the spoiler can be configured with color to meet the personalized needs of consumers.

[0018] In order to achieve the seventh purpose of the present invention, the end buckle forms a flared portion at the bottom of the third clamping groove near the insertion end to facilitate the extraction of the wiper rubber sleeve. The flared portion can achieve the technical effect of quickly replacing the wiper rubber strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The directions of “front” and “rear” in the present invention are consistent with the directions marked in the accompanying drawings in the specification.

[0022] The present invention relates to the fact that the orientations “along the X-axis direction” and “along the length direction” are consistent.

[0023] like Figure 3-1 to Figure 3-4 As shown, a series bearing component 10a is used as an intermediate connecting component between the elastic supporting component 2 and the wiper rubber strip 3. Figure 3-1 As shown, it includes a first bearing component 1a, a second bearing component 1a, a third bearing component 1a, a fourth bearing component 1a...the Nth bearing component arranged in sequence along the X-axis direction, where N is a positive integer greater than 2. The various bearing components 1a are made of hard plastic material and have the same structure, but the length of each bearing component 1a can be adjusted to different lengths according to design requirements. The various bearing components 1a disclosed in the present invention have consistent sizes and structures, which is conducive to saving mold costs, simplifying the assembly process and thus reducing the overall manufacturing cost.

[0024] like Figure 3-3 As shown, each of the supporting components 1a is provided with a first receiving groove 11 and a first clamping groove 12 from top to bottom. The first receiving groove 11 includes a cavity 111 that is formed by a bottom wall a, two side walls b and a top wall c and passes through along the X-axis direction. The cavity 111 is provided with at least one first receiving channel T that is only for the elastic support component 1a to pass through. The first receiving channel T limits the relative displacement of the elastic support component 2 relative to the supporting component 1a along the height and width directions. In this embodiment, the first receiving channel T is jointly constructed by respectively arranging an opening and relatively setting a U-shaped slide groove 1111 in the width direction of the cavity 111. The bottom walls of the two U-shaped slide grooves 1111 are connected to form the bottom wall a of the first receiving groove 11. The first clamping groove 12 is composed of a pair of longitudinal hooks 121 fixed to the bottom of the bottom wall a and extending along the X-axis direction. The bent parts of the two longitudinal hooks 121 are relatively set to form a clamping gap. The clamping space constructed by the two longitudinal hooks 121 is used to clamp the wiper rubber strip 3 (as shown in FIG. Figure 3-5 ), it should be noted that, since the bearing component 1a is an integral component, a transverse connecting member needs to be constructed between the two side walls b. In actual design, the bottom wall a and / or top wall c connecting the two side walls b can be regarded as a transverse connecting member, such as Figure 3-3 , the bottom wall a connects the bottoms of the two side walls b, such as Figure 3-7 , the top wall c connects the tops of the two side walls b.

[0025] like Figure 3-2-1 to Figure 3-2-2, the top wall c and the upper sections of the two side walls b of the first accommodating groove 11 disclosed in this embodiment are staggered with the bottom wall a along the X-axis direction, that is, the top wall c and the two side walls b form a clearance section M1 at the front end, the upper sections of the two side walls b and the top wall c extend backward to form an extension section M2, and the bottom wall a is provided with a first card block 13a protruding upward at the front end on both sides of the clearance section M1 area, forming a first insertion space 131a between the first card block 13a and the corresponding side wall b, and a second card block 14a is provided downward at the rear end of the two side walls b at the extension section M2, forming a second insertion space 141a between the second card block 14a and the corresponding side wall b, as shown in FIG. Figure 3-4 The two adjacent bearing parts 1a are nested with each other in the height direction through the first clamping block 13a and the second clamping block 14a, that is, the second clamping block 14a of the bearing part 1a at the front end is inserted downward into the first insertion space 131a of the bearing part 1a at the rear end, and the first clamping block 13a of the bearing part 1a at the rear end is just inserted upward into the second insertion space 141a of the bearing part 1a at the front end, so that the first clamping block 13a and the second clamping block 14a of the two adjacent bearing parts 1a leave a gap between each other along the X-axis direction, thereby limiting the two adjacent bearing parts 1a along the X-axis direction. The first clamping block 13a is defined as the first connecting portion at the front end of the supporting component 1a, and the second clamping block 14a is defined as the second connecting portion at the rear end of the supporting component 1a. The two adjacent supporting components 1 are connected to each other through the corresponding first connecting portion 13a and the second connecting portion 14a, so that the two adjacent supporting components 1a are physically connected along the X-axis direction, and when the elastic supporting component 2 is inserted into the first accommodating channel T of each supporting component 1a, the angle α between the two adjacent supporting components 1a can be adaptively adjusted according to the bending curvature of the elastic supporting component 2 (such as Figure 3-4 ).

[0026] Preferred design, such as Figure 3-2-1 As shown, each of the supporting components 1a has a blocking piece 15a extending outwardly along the X-axis direction from the end wall located at the front end of the top wall c of the first accommodating groove 11. The extension section M2 of each supporting component 1a forms a material removal portion at a position relative to the blocking piece 15a. The blocking piece 15a can be inserted into the inner wall side of the extension section M2 of the top wall c of the adjacent supporting component 1a to form a visual barrier at the seam between the top walls c of two adjacent supporting components 1a, thereby enhancing the design aesthetics of the product. Figure 3-8 , which discloses another structural form of a blocking piece 15b, the blocking piece 15b extends forward from the front end wall of the top wall c and the side wall b respectively, and its longitudinal cross section is an "inverted L-shaped", compared with the previously disclosed blocking piece 15a ( Figure 3-2-1 ), the blocking piece 15b increases the shielding of the joint between the side walls c of two adjacent carrying components 1a, further enhancing the design aesthetics of the overall product.

[0027] like Figure 4-1 to Figure 4-3 The present invention discloses a second embodiment of the first connecting portion 13b and the second connecting portion 14b of the bearing component 1a. The structures of the first accommodating groove 11 and the first clamping groove 12 of the bearing component 1a are basically the same as the structure of the aforementioned bearing component. The top wall c and the two side walls b form a giving section M1 at the front end, and the two side walls b and the top wall c extend backward to form an extension section M2. At least the wall thickness of the extension section M2 relative to the side wall b is smaller than that of the side wall b; the bottom wall a is respectively biased inwardly on both sides of the front end of the giving section M1 area to form a third clamping block 131b, so that the third clamping block 131b forms a third insertion space 132b and a spacing s between the corresponding side walls b and the side of the bottom wall a, and the spacing s is equal to the wall thickness of the extension section M2. Matching, the third blocking block 131b is defined as the first connecting portion 13b; a protrusion 14b is protruded along the height direction at the rear end of the inner side wall of the extension section M2, and a fourth insertion space 141b exists between the protrusion 14b and the opposite side wall b, and the protrusion 14b is defined as the second connecting portion 14b. When the two adjacent bearing parts 1a are spliced ​​with each other along the length direction, the extension section M2 of the bearing part 1a at the front end is placed on the yield section M1 area of ​​the bottom wall a of the rear end bearing part 1a, so that the protrusion 14b and the fourth insertion space 141b of the two adjacent bearing parts 1a are respectively nested and matched with the corresponding third insertion space 132b and the third blocking block 131b along the length direction, thereby limiting the two adjacent bearing parts 1a from disengaging from each other along the X-axis direction.

[0028] More preferably, Figure 4-1The top of the third block 131 extends inward and backward along the width direction toward the front end wall of the top wall c to form a horizontal reinforcement block 133b. The structural strength of the third block 131 can be further increased by the horizontal reinforcement block 133b, and the first connecting portion 13b is jointly constructed by the horizontal reinforcement block 133b and the third block 131b; the extension segment M2 of each of the load-bearing components 1a forms a material removal portion at a position relative to the horizontal reinforcement block 133b, so that the horizontal reinforcement block 133b can be inserted into the inner wall side of the extension segment M2 of the adjacent load-bearing component 1a. At the same time, the horizontal reinforcement block 133b also has a function of visually blocking the joint of the two adjacent load-bearing components 1a at the top wall c. With this structure, the second connecting portion 14b (bump) is arranged on the inner side wall of the extension section M2, and its height can be basically flush with the height of the inner side wall of the extension section M2. At the same time, the third clamping block 131b can be configured to have a sufficiently long height, as long as there is a certain gap between the top of the third clamping block 131b and the inner top wall of the extension section M2 and they do not interfere with each other. Therefore, there is a sufficient contact and abutment area between the third clamping block 131b and the bump 14b along the height direction, which can greatly improve the assembly efficiency between the various bearing components 1a, and at the same time can further improve the stability of the connection between adjacent bearing components 1a along the length direction.

[0029] like Figure 5-1 The present invention discloses a third embodiment of the first connecting portion 13c and the second connecting portion 14c of the bearing component 1a. Two first connecting portions 13c and second connecting portions 14c are respectively provided on both sides of the front end and the rear end of each receiving component 1a. Specifically, a plug-in column 13c is protruded outward from the front end wall of each side wall b of each bearing component 1a. The plug-in column 13c is composed of a large-diameter portion 131c and a straight rod section 132c. The large-diameter portion 131c is in the shape of a triangular column. The plug-in column 13c is defined as the first connecting portion 13c. A socket groove is provided on the rear end wall of each side wall b of the bearing component 1a relative to the position of the plug-in column 13c. 14c, the socket slot 14c is sequentially configured from the inside to the outside with a receiving cavity 141c for receiving the large diameter portion 131c and a constriction 142c for limiting the large diameter portion 131c from being separated from the receiving cavity. The inner contour of the receiving cavity 141c matches the outer contour of the large diameter portion 131c. The socket slot 14c is defined as a second connecting portion 14c. The large diameter portion 131c of the plug post 13c is inserted and nested in the receiving cavity 141c of the socket slot 14c. It and the socket slot 14c can generate a certain axial movement along the X-axis direction and / or form a yielding mating surface between the mating surfaces of the two adjacent bearing components 1a, which can provide a clearance angle α between the two bearing components 1a. Figure 5-2The inventive concept of the first connection part 13c' and the second connection part 14c' of the two adjacent bearing parts 1a is basically the same as the aforementioned first connection part 13c and the second connection part 14c, except that the large diameter part of the plug column of the first connection part 13c' in this embodiment is disc-shaped, and correspondingly, the accommodating cavity of the socket groove of the second connection part 14c' is a disc cavity that matches the outer contour of the large diameter part of the first connection part 13c'.

[0030] In summary, the first inventive concept of the present invention is to connect the independent load-bearing components 1a, which are made of hard plastic, with a first connecting part 13a, 13b and 13c set at the front end of each load-bearing component 1a and a second connecting part 14a, 14b and 14c set at the rear end, so that the two adjacent load-bearing components 1a are physically connected along the X-axis direction by utilizing the mutual connection of the first connecting part 13a, 13b and 13c and the second connecting part 14a, 14b and 14c, and when the elastic support component 2 is placed in the first accommodating channel T of each load-bearing component 1a, the angle α between the two adjacent load-bearing components 1a can be adaptively adjusted according to the bending curvature of the elastic support component 2.

[0031] The present invention also discloses a technical solution in which each of the above-mentioned bearing components 1a can be loaded with a spoiler 4, and the bearing component 1a is further provided with a mounting portion for assembling the spoiler 4, such as Figure 3-5 The spoiler 4 includes a guide portion 41 and a matching portion 42a from top to bottom. The guide portion 41 has an aerodynamic guide surface. The matching portion 42a is used to connect with the mounting portion on the supporting component 1a. Since the matching portion has different structures, the matching mounting portion also needs to be changed accordingly. More specifically, as Figure 3-5 The disclosed mating portion 42a of the spoiler 4 is composed of a vertical section 421a and a transverse section 422a, which is roughly in the shape of a "mountain", and the two ends of the transverse section 422a are convex upward to form arc chamfers; the mounting portion 16a is a notch 162a provided on the central axis of the top wall c for the vertical section 421a of the mating portion 42a of the spoiler 4 to pass through. It is located in the cavity 111 of the first accommodating groove 11 and above the first accommodating channel T to form a second accommodating channel 161a with an inner cavity contour also roughly in the shape of a "mountain", and the second accommodating channel 161a and its notch 162a allow the mating portion 42a of the spoiler 4 to be nested and passed through each other. Figure 3-6, which discloses another embodiment of a spoiler 4, in which the vertical section 421b of the matching portion 42b of the spoiler 4 has a wider spacing. In the design, the vertical section 421b is divided into two so that the two parallel sections are spaced apart. The transverse section 422b is connected to the adjacent vertical section 421b, so that the entire matching portion 421b is roughly in the shape of a "child"; the mounting portion 16b of the bearing component 1a is provided with a wider notch 162b on the top wall c, and the second accommodating channel 161b is provided in the accommodating cavity 111 of the first accommodating groove 11 and is located above the first accommodating channel T. Its internal contour is basically the same as the aforementioned second accommodating channel 161a, and the matching portions 42b of the spoiler 4 are nested and penetrated through the second accommodating channel 161b and its notch 162b. As Figure 3-7 The mating portion 42c of the spoiler 4 is in an inverted T shape, and the mounting portion 16c of the bearing component 1a is arranged above the top wall c. That is, a second accommodating channel 161c is provided above the top wall c, and is nested with the mating portion 42b. The top of the second accommodating channel 161c forms an opening, and the mating portions 42c of the spoiler 4 are nested and passed through the second accommodating channel 161c. Figure 3-8 and Figure 3-9 The matching portion 42d of the spoiler 4 is composed of two L-shaped bent portions arranged at intervals, and the bent portions are arranged opposite to each other. The mounting portion 16d of the bearing component 1a is composed of two "C-shaped components" with openings facing each other and extending in the length direction. A second accommodating channel 161d that matches the L-shaped bent portion is formed in the accommodating cavity of the "C-shaped component". The matching portions 42d of the spoiler 4 are nested and penetrated by each other through the second accommodating channel 161d. In short, each of the above-mentioned bearing components 1a is mutually penetrated and nested through the second accommodating channels 161a, 161b, 161c and 161d arranged above the first accommodating channel T of the first accommodating groove 11 and the corresponding matching portions 42a, 42b, 42c and 42d of the spoiler 4, thereby limiting the relative displacement of the spoiler 4 relative to the bearing component 1a in the height and width directions. It should be noted that if the mating portions 42a, 42b, 42c and 42d of the above-mentioned spoilers 4 are integrated with the mounting portions 16a, 16b, 16c and 16d of the corresponding supporting component 1a, it can also be regarded as a different embodiment of directly configuring the aerodynamic guide portion 41 on the supporting component.

[0032] like Figure 6-1 to Figure 6-4The present invention also discloses a bearing component 1b directly configured with an aerodynamically compliant air guide 41, that is, the air guide 41 and the base body w of the bearing component 1b are integrally formed, and the base body w is configured with a first accommodating groove 11 and a first clamping groove 12 from top to bottom. The material of the air guide 41 is consistent with the material of the base body w (made of hard plastic), or a material different from the base body w (such as a flexible material) is integrally formed. As for the mutual connection between the various bearing components 1b, reference can be made to the aforementioned invention structure of the mutual connection between two adjacent bearing components 1a. Here, this embodiment discloses a first connecting portion 13d and a second connecting portion 14d not previously mentioned. The seat body w and the guide portion 41 are staggered along the length direction, that is, the guide portion 41 forms a clearance section M1 at the front end relative to the top wall c and the two side walls b (the seat body w), and the guide portion 41 extends backward relative to the top wall c and the two side walls b (the seat body w) to form an extension section M2. It should be emphasized that the guide portion 41 here can only be made of hard plastic. The guide portion 41 is composed of a first guide surface 411 and a second guide surface 412. 12 encloses to form a cover body with an opening facing downward, and the cover body covers the outer sides of the top wall c and the two side walls b. A convex portion is formed at the intersection of the first guide surface 411 and the second guide surface 412. The top wall c is provided with a limit pin 13d extending in the X-axis direction at the position of the convex portion of the guide portion 41 and located in the yield section area M1. The end of the limit pin 13d forms a large diameter portion. The limit pin 13d is defined as the first connecting portion 13d. The guide portion 41 is located on the inner wall side of the extension section M2 and relative to the limit pin. An insertion groove 14d is opened at the position of the pin 13d, and the insertion groove 14d is composed of two spaced-apart blocks 141d protruding from the first guide surface 411 and the second guide surface 412. The spacing between the blocks 141d is smaller than the maximum width of the large diameter portion of the limit pin 13d. The insertion groove 14d is defined as the second connecting portion 14d. The limit pin 13d is inserted through the insertion groove 14d, and the large diameter portion of the limit pin 13d and the block 141d are mutually engaged, thereby limiting the two adjacent bearing components 1b from disengaging from each other along the X-axis direction.

[0033] The present invention also discloses a boneless wiper made using any of the above-mentioned load-bearing components 1a and 1b. There are two main embodiments. The first type is that the load-bearing component 1a needs to be loaded with a spoiler 4, and the second type is the load-bearing component 1b that is directly configured with a guide portion 41. The two load-bearing components have slight differences in structure, which are now explained in detail.

[0034] The first type: taking the supporting component 1a configured with the first connecting portion 13b and the second connecting portion 14b of the second embodiment as an example, the frameless wiper assembled by the supporting component 1a is described.

[0035] like Figure 2-1 to Figure 2-2The present invention also discloses a boneless wiper 100, which includes an elastic support component 2, a wiper rubber strip 3, two end buckles 6, the aforementioned plurality of bearing components 1a and a wiper arm mounting assembly 5; The wiper arm mounting assembly 5 includes, from bottom to top, a fixed base 51 and a wiper joint assembly 52. ​​The upper portion of the fixed base 51 is directly integrally formed with the wiper joint assembly 52 or is configured in a detachable / installable manner. The wiper joint assembly 52 is connected to the wiper arm 200 through the wiper joint assembly 52. ​​The fixed base 51 is sequentially configured with a third accommodating channel 511 and a second clamping groove 512 from top to bottom. The third accommodating channel 511 is used for allowing the elastic support component 2 to pass through. At least one first locking portion 513 is configured in the third accommodating channel 511. The third accommodating channel 511 is positioned opposite to the first accommodating channels T of two adjacent receiving components 1a. The second clamping groove 512 is positioned opposite to the first clamping groove 12 of two adjacent bearing components 1a. It is used for allowing the wiper rubber strip 3 to pass through and clamp. The respective bearing components 1a are assembled into two groups of bearing component assemblies 10a along the X-axis direction. The two bearing component assemblies 10a are respectively arranged at both ends of the fixed base 51. No connecting components are required between the fixed base 51 and the two adjacent bearing components 1a. The bearing component assemblies 10a are clamped between the fixed base 51 and the end buckles 6 described later. A more preferred arrangement is as follows: Figure 7-1 and Figure 7-2 The two groups of bearing component assemblies 10a are arranged at both ends of the fixed base 51 in a mirror-image manner, so that the first connection parts 13b or the second connection parts 14b of the two bearing components 1a adjacent to the fixed base 51 are synchronously directed toward the fixed base 51. Taking the first connection part 13b directed toward the fixed base 51 as an example, the first connection parts 13b of the bearing components 1a at both ends of the fixed base 51 are both directed toward the fixed base 51. Correspondingly, the top wall and the two side walls of the fixed base 51 form extension sections M2 along the length direction to both ends respectively, and the second connection part 14b is formed correspondingly on the inner side wall of the extension section M2. The structure of the second connection part 14b is consistent with the structure of the second connection part 14b of the bearing component 1a. By connecting the first connection part 13 and the second connection part 14, the fixed base 51 is physically connected with the two adjacent bearing components 1a, further increasing the stability of the connection between the fixed base 51 and the bearing component assembly 10a.

[0036] like Figure 2-2The two spoilers 4 are respectively arranged at both ends of the scraper arm mounting assembly 5, and include a guide portion 41 and a matching portion 42 from top to bottom. The guide portion 41 has an aerodynamic profile, and the matching portion 42 is used to penetrate and nest with the second accommodating channel 161a of the mounting portion 16a of each bearing component 1a, so that the spoiler 4 is assembled to the corresponding bearing component assembly 10a, and generates upward limit in the height direction and in the width direction with it; more preferably, the guide portion 41 of the spoiler 4 can be configured with color to meet the personalized needs of consumers.

[0037] Figure 1, Figure 8-1 to Figure 8-3 As shown, the middle part of the elastic support component 2 is provided with a second locking portion 21 at a position relative to the first locking portion 513, and a limiting portion 22 is provided at both ends thereof. One embodiment of the limiting portion 22 is a limiting slot 22 provided on both sides of the elastic support component 2, and the elastic support component 2 is inserted into the first accommodating channel T of the first accommodating groove 11 of each receiving component 1a and the third accommodating channel 511 of the fixed base 51, and the relative displacement of the elastic support component 2 and the fixed base 51 along the length direction is limited by the mutual limitation of the first locking portion 513 and the second locking portion 21; wherein an embodiment of the second locking portion 21 is involved, and the second locking portion 21 of the elastic support component 2 is achieved by adding a positioning spring piece 20 on the elastic support component 2. The positioning spring piece 20 does not produce relative displacement with the elastic support component 2 along the X-axis direction, and two upward-curving folding pieces 21 are arranged at intervals on the positioning spring piece 20. The folding pieces are defined as the second locking portion 21. Correspondingly, the first locking portion 513 is a positioning protrusion arranged on the inner top wall of the third accommodating channel 511. The positioning protrusion 513 is provided with two abutting surfaces 5131 along the X-axis direction. The two abutting surfaces 5131 and the free ends of the two upward-curving folding pieces 21 abut against each other, thereby limiting the position of the elastic support component 2 and the fixed base 51 along the X-axis direction. Of course, the positioning protrusion 513 can be a single protrusion or two protrusions arranged at intervals, as long as the abutting surfaces 5131 are formed on the two upward-curving folding pieces 21 of the positioning spring piece 20. At the same time, the second clamping groove 512 is continuous and uninterrupted along the X-axis direction (such as Figure 8-2 ).

[0038] The wiper rubber strip 3 is sequentially inserted into the first clamping groove 12 of each receiving component 1a and the second clamping groove 512 of the wiper arm mounting assembly 5; like Figure 9, one end of the end buckle 6 along the X-axis direction is an insertion end, and the other end is a closed end, which is respectively provided with a spoiler accommodating cavity 61, a fourth accommodating channel 62 and a third clamping groove 63 from top to bottom. The inner contour of the spoiler accommodating cavity 61 matches the outer contour of the guide portion 41 of the spoiler 4, which is used to cover the end of the spoiler 6 therein, the fourth accommodating channel 62 is opposite to the first accommodating channel T of the adjacent bearing component 1a, and its inner wall side is opposite to the limit card groove 2 of the elastic support component 2 2 is provided with a clamping block 621, the end of the elastic support component 2 is inserted into the fourth accommodating channel 62, and the end buckle 6 is clamped and fixed to the elastic support component 2 by the mutual engagement of the limiting clamping groove 22 and the clamping block 621. The third clamping groove 63 is opposite to the first clamping groove 12 of the adjacent bearing component, and is used to accommodate and limit the end of the wiper rubber strip 3, so that the wiper rubber strip 3 is restricted between the two end buckles 6 along the X-axis direction, thereby completing the assembly of the boneless wiper.

[0039] like Figure 10 Since the mounting portions 16a, 16b, 16c and 16d of the various structural forms of the support component 1a disclosed in the present invention for mounting the spoiler 4 are all arranged above the first accommodating channel T, the boneless wiper 100 of the present invention also discloses an innovative design for the end buckle 6, that is, the end buckle 6 is composed of a cover 64 and a base 65, and the cover 64 and the base 65 can be switched between an open state and a closed state, such as Figure 11-1 The fourth accommodating channel 62 and the third clamping groove 63 are arranged on the seat body 65. When the covering cover 64 is in the open state, the spoiler 4 can be pulled outward without interfering with the covering cover 64. When the covering cover 64 is in the closed state, the spoiler 4 will be constrained in the spoiler accommodating cavity 61 set by the covering cover 64, thereby limiting the spoiler 4 from being pulled outward.

[0040] The cover 64 and the seat 65 can adopt different structural forms to achieve the switching between the open state and the closed state. Preferably, the inner contour of the cover 64 matches the outer contour of the guide portion 41 of the spoiler 4, specifically: like Figure 11-1As shown, the cover 64 and the base 65 are flipped over by a rotating shaft matching portion 652, and the inner walls of the two side walls of the cover 64 are respectively provided with protruding blocks 641, and the corresponding two sides of the base 65 are provided with stop surfaces 651, and the block 641 is provided with a locking inclined surface 642 facing the stop surface 651. The cover 64 is flipped over with the base 65 through the rotating shaft matching portion 652, and the stop surfaces 651 on both sides are snapped into the block 641 along the two locking inclined surfaces 642 to achieve the locking state of the stop surface 651 and the block 641. At this time, the cover 64 and the base 65 are closed. If it is necessary to open the cover 64, it only needs to be pried open with hard force and the cover 64 is rotated to open it along the rotating shaft matching portion 652. Because the material has a slight elasticity, it does not require too much force to pry open the cover, and it will not damage the product.

[0041] More preferably, Figure 11-2 , elastic cantilevers 653 are respectively provided on both sides of the seat body 65, and the stop surfaces 651 on both sides are respectively provided on the elastic cantilevers 653. By pressing the elastic cantilevers 653 with external force, the stop surfaces 651 can be retracted inward, and hollow notches 643 are respectively reserved at the corresponding positions of the two side walls of the covering cover 64 for placing the elastic cantilevers 653 when in the closed state. When the spoiler needs to be removed, it is only necessary to press the elastic cantilevers 653 on both sides inward to make the stop surfaces 651 retract inward. At this time, the stop surfaces 651 leave the block 641, and the covering cover 64 can be flipped open, and the spoiler 4 can be removed.

[0042] In actual use, the angle at which the cover 64 and the seat 65 are flipped open is greater than 90 degrees, and is preferably designed to be greater than 100 degrees, which makes it easier to remove the spoiler. In this embodiment, Figure 11-3 As shown, sufficient redundant space 649 is provided at the rotation axis position of the cover 64, which is suitable for the cover 64 to be flipped to a 180-degree position with the base, thereby providing the best space for the spoiler to be pulled out.

[0043] like Figures 12-1 to 12-14 As shown, the cover 64 and the base 65 adopt different embodiments of the sliding cover matching structure: The cover 64 and the seat 65 are opened and closed directly by pushing in a manner similar to a sliding cover. The inner wall sides of the two side walls of the cover 64 are respectively provided with transverse ridges 647, and the corresponding two sides of the seat 65 are provided with transverse grooves 654. The transverse ridges 647 are pushed one by one along the transverse grooves 654 to close the cover 64 and to open them by pushing in the opposite direction. In actual application, a slot 648 is provided on the ridge 647, and a protruding card point 656 is provided at a corresponding position on the inner wall 655 of the transverse groove 654. When the cover 64 and the seat 65 are just closed, the card point 656 is just snapped into the card slot 648 of the ridge 647 to achieve positioning; when it needs to be opened, it is only necessary to push the cover 64 in the opposite direction to achieve the separation of the cover 64 and the seat 65. Both sides of the card slot 648 are designed as oblique guides to facilitate the snapping in and out of the card point 656.

[0044] In the embodiment, the transverse grooves 654 can be provided at the upper, middle or lower portions of both sides of the base 65, and the transverse ridges 647 of the two side walls of the cover 64 are respectively designed at corresponding positions; Figure 12-1 As shown, the transverse slide grooves 654 are provided on both sides of the upper portion of the seat body 65; Figure 12-3 As shown, the transverse slide groove 654 is provided in the middle of both sides of the seat body 65; Figure 12-5 As shown, the transverse slide grooves 654 are provided at the lower portions of both sides of the seat body 65; Figures 12-1 to 12-6 In the figure, both sides of the covering cover 64 are designed to completely cover both sides of the seat body 65, and a transverse ridge 647 is provided at the corresponding position of the inner wall of the covering cover 64, which is used to open or close with the seat body 65 by pushing the sliding groove. Such a design is conducive to enhancing the use strength of the two after closing and assembling.

[0045] In other embodiments, it is further shown that when the upper part of the base 65 is provided with a transverse groove 654 on both sides, the cover 64 can also be designed as a flat cover or an embedded cover mode, such as in Figure 12-7 As shown in FIG, the flat cover mode is that the bottom of the cover 64 is set as a horizontal convex edge 647, which is pushed to close and open with the base 65 by a sliding groove; or Figure 12-9 、 12-10 In the embedded cover mode, the cover 64 is actually embedded in the upper opening of the base body 65. The base body 65 is the base of the whole, and the cover 64 is an auxiliary form. Different forms of design are suitable for different forms of use occasions.

[0046] In other embodiments, Figures 12-11 to 12-14As shown, there are no card points on the horizontal grooves 654 on both sides of the seat body 65, and there are no card slots on the horizontal ridges 647 on the side walls of the covering cover 64. Instead, another structure is used to achieve its positioning. Specifically, the cover surface 645 of the covering cover 64 is provided with a downwardly protruding spring block 646, and the corresponding position of the seat body 65 is provided with a bayonet 657. When the horizontal ridge 647 of the covering cover 64 slides along the horizontal groove 654 in the closing direction, the spring block 646 is just stuck in the bayonet 657 of the seat body 65, thereby realizing the position limiting function when they are closed to each other.

[0047] like Figures 13-1 to 13-6 As shown, the cover 64 and the base 65 adopt different embodiments of the up-down plug-in matching structure: Figure 13-1 、 13-2 As shown, the cover 64 and the base 65 are opened and closed directly by interlocking vertically. The cover 64 is provided with outwardly facing first inserts 7 on either side of the cover. In this embodiment, each side wall has two outwardly facing first inserts 7. Two corresponding first slots 73 are provided on either side of the open upper end of the base. Furthermore, the first inserts 7 are designed to have ends that are raised upward to form a first latching edge 71. A corresponding first stop edge 74 is provided within the first slot 73. The first inserts 7 are also provided with a first inclined guide surface 72 on the exterior. When the cover 64 is tightly closed over the base 65, the first inclined guide surface 72 of each first insert 7 snaps along the first stop edge 74 of the first slot 73 until the first latching edge 71 fits neatly under the first stop edge 74, achieving a fixed vertical connection. To open the cover 64 and base 65, the cover 64 is simply pulled upward. Due to the elasticity of the cover 64, the first latching edge 71 of the first insert 7 naturally clears the first stop edge 74 of the first slot 73, thereby separating the cover 64 from the base 65.

[0048] In other embodiments, Figure 13-3 、 13-4As shown, the sides of the cover 64 are designed to completely enclose the base 65. Two inwardly disposed second inserts 8 are provided on either side of the inner wall of the cover 64. These inserts 8 have an upwardly raised second latching edge 81, and a second inclined guide surface 82 is disposed on the outer side of the second latching edge 81. Two corresponding second slots 83 are provided on each side wall of the base, each of which also has a second stop edge 84. When the cover 64 is lowered to cover the base 65, the second inclined guide surface 82 of each second insert 8 snaps into place along the upper end of the second stop edge 84 of the second slot 83. In this embodiment, the upper end of the second stop edge 84 is designed as an arc 85, which facilitates the second inclined guide surface 82 to cut downward until the second latching edge 81 fits neatly under the second stop edge 84, achieving a fixed connection. To open the cover 64 and base 65, simply pull up the cover 64, and the second latching edge 81 of the second insert 8 naturally clears the second stop edge 84 of the second slot 83, thereby separating the cover 64 from the base 65.

[0049] In other embodiments, Figure 13-5 、 13-6 As shown, the cover 64 and the base 65 are opened and closed directly by plugging in up and down. The base 65 is respectively provided with four (two rows) upward third plug blocks 9, and the corresponding positions of the cover 64 are respectively provided with four third slots 93. Furthermore, the third plug blocks 9 are designed to form a third clamping edge 91, and a corresponding third stop edge 94 is provided in the third slot 93. The end of the third plug block 9 is provided with a third inclined guide surface 92. When the cover 64 covers the base 65 downward, the third inclined guide surface 92 of each third plug block 9 is inserted along the third stop edge 94 of the third slot 93 until the third clamping edge 91 is just inserted into the third stop edge 94, thereby achieving fixed insertion up and down.

[0050] Through the above-mentioned different structural forms, the covering cover 64 and the base body 65 can be switched between the open state and the closed state, so that the boneless wiper spoiler 4 can be quickly replaced. Therefore, the technical effect of replacing the spoiler 4 can be achieved at the end buckle 6, breaking the traditional consumer habit that the spoiler 4 assembled on the original boneless wiper is not configured with color. When the boneless wiper is sold, it is also equipped with spoilers of different colors for users to choose, which greatly meets the personalized needs of consumers.

[0051] like Figure 11-4 and Figure 11-5The present invention also provides an inventive concept for realizing the rapid replacement of the wiper rubber strip 3 of the boneless wiper 100, wherein the end buckle 6 forms a flared portion 66 at the bottom wall of the third clamping groove 63 and adjacent to the insertion end of the wiper rubber strip 3, which is convenient for pulling out the wiper rubber strip 3. Through the flared portion 66, the consumer can conveniently pull out the old wiper rubber strip from the flared portion 66, and then insert the new wiper rubber strip 3 from the flared portion 66 into the first clamping groove 12 of each bearing component 1a, the second clamping groove 512 of the fixed base 51 and the third clamping groove 63 of the end buckle 6 (not shown), thereby completing the assembly of the new wiper rubber strip 3; preferably, the length L1 from the third clamping groove 63 located on the closed end side to the access end of the flared portion 66 is [10mm 30mmm】, through the setting of the above-mentioned length L1, there is enough reserved length from the end of the wiper strip 3 to the flared portion 66, which prevents the wiper strip 3 from accidentally popping out from the flared portion 66 of the end buckle 6 during the wiping operation of the boneless wiper, thereby causing the wiper strip and the boneless wiper to separate from each other.

[0052] The second type: the bearing component 1b is equipped with an integrally formed flow guide.

[0053] This type of boneless wiper is consistent with the main inventive concept of the first type of boneless wiper, that is, using each independent bearing component 1b, and then using the first connecting part and the second connecting part at the front end of the bearing component 1b to realize the series connection between multiple bearing components 1b, thereby constructing a corresponding bearing component assembly, the matching structure of the bearing component 1b and the elastic support component 2, the matching structure of the bearing component assembly formed by the series connection of each bearing component 1b and the wiper arm mounting assembly 5, how the elastic support component 2 and the fixed base 51 of the wiper arm mounting assembly 5 limit each other along the length direction, and the end buckle 6 is connected to the elastic support component 6, these structures are the same as the boneless wiper structure configured with the first type of bearing component 1a, and will not be repeated here. It is just that the bearing component 1b is integrally formed with the guide part, so the configuration of the spoiler 4 is omitted. At the same time, the design of the mounting part is also omitted in the first accommodating groove 11 of the bearing component 1b. At the same time, the end buckle 6 does not need to adopt the setting method of the covering cover 64 and the seat body 65 being movably connected. However, in this boneless wiper, the end buckle 6 can also be configured with a structural scheme of configuring the flared part 66 on the bottom wall of the third clamping groove 63 to facilitate the replacement of the wiper strip 3.

[0054] In addition, it is preferably designed that the distance between the front end walls of the two first clamping grooves 12 of any two adjacent bearing components 1a, 1b when the bearing components 1a and 1b are in the assembled state is set to 12.5mm±0.3mm or 25mm±0.3mm; this design is that the sizes of different models of wiper products are generally increased or decreased by integer multiples of inches, the legal standard inch is 25.4mm, and it is generally calculated by rounding off 25mm. Therefore, the single bearing components 1a, 1b are designed to be approximately half the length of an inch or an integer multiple of an inch, which is conducive to increasing or reducing the wiper size to the corresponding model, allowing each side to increase or decrease its size to meet the requirement of integer multiples of inches by adding or reducing one bearing component.

[0055] The above embodiments and illustrations do not limit the product form and style of the present invention. Any appropriate changes and modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
