Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a wiper frame and a wiper. Background Art

[0002] Wipers are one of the important parts of a car. They can remove dirt from the windshield, provide the driver with a clear driving view, and ensure the driver's driving safety. As consumers' awareness of vehicle safety increases, more and more people realize the importance of wipers.

[0003] In order to ensure that the wiper strips have a good cleaning effect on the windshield, it is necessary to ensure that there is a reasonable amount of interference between the wiper strips and the windshield. If the interference is too large, the wiper strips may make abnormal noises when moving and have difficulty moving. If the interference is too small (that is, the wiper strips have a low fit with the windshield), the scraping force of the wiper strips may not be enough.

[0004] However, due to production process deviations, material properties and other reasons, the interference between the existing wiper strips and their auxiliary structures such as the frame for installing the wiper strips and the windshield may not be within a reasonable range after they are actually produced and assembled, which ultimately leads to poor cleaning effect or abnormal noise during operation. Summary of the Invention

[0005] The technical problem that the present invention aims to solve is that it is difficult to ensure good working performance of the existing wiper frame after production and assembly.

[0006] The present invention provides a wiper frame, comprising an outer frame shell, an inner frame, a connecting piece and a fastener;

[0007] A first opening extending along the length direction of the exoskeleton shell is provided on one side of the exoskeleton shell;

[0008] The inner frame is used to be movably connected to the inner side wall of the outer frame shell through the connecting member, so that the inner frame has at least one degree of freedom relative to the outer frame shell, and the at least one degree of freedom is movement along a first set direction, and the first set direction is a direction perpendicular to the plane where the first opening is located;

[0009] The inner frame is used to mount a wiper rubber strip, and allows at least a portion of the wiper rubber strip to extend out of the first opening;

[0010] The fastener is disposed on the outer frame shell, and is used to move relative to the outer frame shell to fix the inner frame relative to the outer frame shell.

[0011] The wiper frame provided by the present invention has, but is not limited to, the following beneficial effects compared to the prior art:

[0012] After the wiper strip, outer frame shell and inner frame are produced and formed, the inner frame can be assembled into the outer frame through connecting parts to complete the assembly of the wiper frame. Then the wiper strip is connected to the inner frame of the wiper frame, for example, the wiper strip part (the part of the wiper strip away from the wiper fitting surface) is embedded in the inner frame, and the wiper fitting surface of the wiper strip extends out of the first opening. After the wiper frame and the wiper strip are assembled, since the inner frame has a first degree of freedom to move along a first set direction after being connected to the outer frame shell through a connecting piece, an adjustment force can be given to the inner frame from the outside. The adjustment force causes the inner frame to move along the first set direction, thereby adjusting the amount of the wiper strip installed on the inner frame extending out of the outer frame shell. After the adjustment is completed, the inner frame can be fixed relative to the outer frame shell by fasteners. When the wiper with the wiper frame is installed on the vehicle, it is equivalent to adjusting the interference between the wiper strip on the inner frame and the windshield glass, so that the interference amount is within a reasonable range, which not only ensures sufficient scraping force, but also avoids the generation of abnormal noise, thereby ensuring good working performance. At the same time, due to the adjustability of the wiper strip installed on the wiper frame, the versatility of the wiper with the wiper frame for different models is increased.

[0013] Furthermore, the inner frame includes a plurality of inner frame units, and the plurality of inner frame units are arranged in sequence along the length direction of the outer frame shell, and the wiper rubber strip is connected to the plurality of inner frame units at the same time;

[0014] The plurality of inner skeleton units are respectively used to be movably connected to the inner wall of the outer skeleton shell through the connecting members, so that the inner skeleton units have the first degree of freedom and the second degree of freedom relative to the outer skeleton shell, the second degree of freedom being rotation around a second set direction, the second set direction being perpendicular to the first set direction, and the second set direction being perpendicular to the length direction of the outer skeleton shell;

[0015] Each of the inner skeleton units is used to be fixed by a corresponding fastener.

[0016] Furthermore, adjacent inner skeleton units are spaced apart, and the sum of the lengths of the plurality of inner skeleton units is less than the length of the outer skeleton shell.

[0017] Furthermore, the connecting member is a spring, one end of the spring is connected to the inner side wall of the outer skeleton shell, and the other end of the spring is connected to the inner skeleton.

[0018] Furthermore, the inner side wall of the outer skeleton shell is provided with a first card slot, the inner skeleton is provided with a second card slot, and the two ends of the spring are used to be respectively inserted into the second card slot and the first card slot.

[0019] Furthermore, the fastener is a bolt threadedly connected to the outer frame shell.

[0020] Furthermore, the fastener is arranged on the outer skeleton shell at a position close to the first opening.

[0021] Furthermore, the exoskeleton shell includes a bottom plate and two side plates arranged opposite to each other, one end of each of the side plates is connected to the bottom plate, the other ends of the two side plates form the first opening between them, and the first setting direction is consistent with the direction from one end to the other end of the side plates;

[0022] The two side panels are respectively provided with the fasteners, and the opposite sides of the inner frame are respectively used for movably connecting with the two side panels through the connecting pieces.

[0023] Furthermore, an operation hole is provided on a side of the outer skeleton shell opposite to the first opening.

[0024] The present invention further provides a wiper blade, comprising a wiper rubber strip and the aforementioned wiper frame, wherein the wiper rubber strip is mounted on an inner frame of the wiper frame.

[0025] Since the technical improvements and beneficial effects of the wiper are the same as those of the wiper frame, the wiper will not be described in detail. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "matched" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] In addition, it should be noted that in the description of the present invention, the terms and nouns in each embodiment, such as "upper", "lower", "front", "back" and other words indicating direction, are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the referred elements and devices must be operated in accordance with the specific directions and defined operations and methods and structures in the specification. Such direction nouns do not constitute a limitation on the present invention.

[0036] A coordinate system XYZ is set in this article, wherein the positive direction of the X axis represents the front, the negative direction of the X axis represents the back, the positive direction of the Y axis represents the left, the negative direction of the Y axis represents the right, the positive direction of the Z axis represents the top, and the negative direction of the Z axis represents the bottom.

[0037] See also Figure 1-Figure 2 A wiper frame according to an embodiment of the present invention comprises an outer frame shell 1, an inner frame 2, a connecting member 4 and a fastener 5;

[0038] A first opening 13 extending along the length direction of the exoskeleton shell 1 (in the up-down direction as shown in the figure) is provided on one side of the exoskeleton shell 1 (the front side as shown in the figure);

[0039] The inner frame 2 is used to be movably connected to the inner side wall of the outer frame shell 1 through the connecting member 4, so that the inner frame 2 has a first degree of freedom relative to the outer frame shell 1, and the first degree of freedom is movement along a first set direction (the front-to-back direction as shown in the figure), and the first set direction is a direction perpendicular to the plane where the first opening 13 is located;

[0040] The inner frame 2 is used to mount the wiper rubber strip 3, and at least a portion of the wiper rubber strip 3 extends out of the first opening 13;

[0041] The fastener 5 is disposed on the outer frame shell 1 , and the fastener 5 is used to move relative to the outer frame shell 1 to fix the inner frame 2 relative to the outer frame shell 1 .

[0042] In this embodiment, after the wiper strip 3, the outer frame shell 1 and the inner frame 2 are produced and formed, the inner frame 2 can be assembled in the outer frame through the connecting piece 4 to complete the assembly of the wiper frame. Thereafter, the wiper strip 3 is connected to the inner frame 2 of the wiper frame, for example, part of the wiper strip 3 (the part of the wiper strip 3 away from the wiper fitting surface) is embedded in the inner frame 2, and the wiper fitting surface of the wiper strip 3 extends out of the first opening 13.

[0043] After the wiper frame and the wiper strip 3 are assembled, since the inner frame 2 is connected to the outer frame shell 1 through the connecting piece 4, the inner frame 2 has a first degree of freedom to move along the first set direction, and an adjustment force can be given to the inner frame 2 from the outside. The adjustment force causes the inner frame 2 to move along the first set direction, thereby adjusting the amount of the wiper strip 3 installed on the inner frame 2 extending out of the outer frame shell 1. After the adjustment is completed, the inner frame 2 can be fixed relative to the outer frame shell 1 through the fastener 5. When the wiper with the wiper frame is installed on the vehicle, it is equivalent to adjusting the interference between the wiper strip 3 on the inner frame 2 and the windshield, so that the interference is within a reasonable range, which not only ensures sufficient scraping force, but also avoids the generation of abnormal noise, and ensures good working performance. At the same time, due to the adjustability of the wiper strip 3 installed on the wiper frame, the versatility of the wiper with the wiper frame for different models is increased.

[0044] It can be understood that a wiper having the wiper frame, that is, the outer frame shell 1 of the wiper frame is installed on the wiper arm, and the wiper arm is arranged on the vehicle body. Due to the adjustability of the wiper strip 3 in the wiper frame, even if the wiper arm is still a traditional structure, it does not hinder the adjustment of the interference amount between the wiper strip 3 and the windshield.

[0045] It should be noted that the wiper rubber strip 3 can be adjusted before the wiper frame is installed on the wiper arm, or after the wiper frame is installed on the wiper arm.

[0046] See also Figure 3 Optionally, the inner skeleton 2 includes a plurality of inner skeleton units 21, and the plurality of inner skeleton units 21 are sequentially arranged along the length direction of the outer skeleton shell 1, and the wiper rubber strip 3 is simultaneously connected to the plurality of inner skeleton units 21;

[0047] The plurality of inner skeleton units 21 are used to be movably connected to the inner wall of the outer skeleton shell 1 through the connecting members 4, so that the inner skeleton units 21 have the first degree of freedom and the second degree of freedom relative to the outer skeleton shell 1, the second degree of freedom being rotation around a second set direction (the left and right direction as shown in the figure), the second set direction being perpendicular to the first set direction, and the second set direction being perpendicular to the length direction of the outer skeleton shell 1;

[0048] Each of the inner skeleton units 21 is used to be fixed by the corresponding fastener 5 .

[0049] In this embodiment, each endoskeleton unit 21 can be mounted within the exoskeleton housing 1 via a connector 4. Furthermore, in addition to providing the endoskeleton unit 21 with the aforementioned first degree of freedom, the connector 4 further provides at least a second degree of freedom, which is rotation about a second predetermined direction. This ensures that each endoskeleton unit 21 can independently rotate relative to the exoskeleton housing 1 about the second predetermined direction. By adjusting the angle between adjacent endoskeleton units 21, the curvature of the wiper strip 3 can be matched to the windshield. This ensures that when a wiper blade equipped with this wiper framework is used on different vehicle models (specifically, different vehicle models have windshields with different curvatures), the wiper strip 3, after angle adjustment, installed by multiple endoskeleton units 21, can maintain a consistent curvature with the corresponding windshield, further enhancing versatility.

[0050] After the displacement of the inner skeleton unit 21 in the first setting direction and the rotation angle around the second setting direction are adjusted, the corresponding inner skeleton unit 21 can be fixed relative to the outer skeleton shell 1 by the fastener 5.

[0051] See also Figure 3 Optionally, adjacent inner skeleton units 21 are spaced apart, and the sum of the lengths of the plurality of inner skeleton units 21 is less than the length of the outer skeleton shell 1 .

[0052] In this embodiment, since two adjacent inner skeleton units 21 are spaced apart, space is provided for the change of the angle between the two adjacent inner skeleton units 21, while ensuring that the two inner skeleton units 21 at both ends do not exceed the ends of the length direction of the outer skeleton shell 1.

[0053] See also Figure 2 Optionally, the connecting member 4 is a spring, one end of the spring is connected to the inner wall of the outer skeleton shell 1, and the other end of the spring is connected to the inner skeleton 2.

[0054] In this embodiment, the connecting member 4 is a spring. Since the spring has the ability to twist and deform in all directions, it can ensure that the inner skeleton unit 21 has at least the aforementioned first degree of freedom and second degree of freedom. At the same time, the structure is simple and the cost is low.

[0055] Optionally, the inner side wall of the outer skeleton shell 1 is provided with a first card slot, and the inner skeleton 2 is provided with a second card slot, and the two ends of the spring are used to be respectively inserted into the second card slot and the first card slot.

[0056] In this embodiment, before the inner skeleton unit 21 is assembled with the outer skeleton shell 1, one end of the spring can be first inserted into the second slot of the inner skeleton unit 21, and then the inner skeleton unit 21 can be inserted into the outer skeleton shell 1 from the first opening 13. As the inner skeleton unit 21 is gradually installed, the other end of the spring will pop into the corresponding first slot on the inner wall side of the outer skeleton shell 1, thereby completing the assembly of the inner skeleton unit 21. After the inner skeleton unit 21 is assembled, since the two ends of the spring are respectively located in the first slot and the second slot, the spring will not fall off accidentally.

[0057] See also Figure 1-Figure 2 Optionally, the fastener 5 is a bolt threadedly connected to the exoskeleton shell 1.

[0058] In this embodiment, the outer skeleton shell 1 is provided with a plurality of screw holes along its length direction, each of which is connected with a bolt, and the inner skeleton unit 21 can be locked and fixed by the bolts at the corresponding positions.

[0059] See also Figure 2 Optionally, the fastener 5 is arranged on the exoskeleton shell 1 near the first opening 13 .

[0060] In this embodiment, since the bolts are arranged at a position close to the first opening 13 , it is possible to ensure that the inner skeleton unit 21 has a maximum adjustment stroke along the first set direction.

[0061] See also Figure 2 Optionally, the exoskeleton shell 1 is a strip-shaped C-shaped plate, that is, the exoskeleton shell 1 includes a bottom plate 12 and two side plates 11 arranged opposite to each other, one end of the two side plates 11 (one end in the width direction, the rear end as shown in the figure) is respectively connected to the bottom plate 12, and the other end of the two side plates 11 (the other end in the width direction, the front end as shown in the figure) forms the first opening 13 between them, and the first setting direction is the width direction of the side plates 11;

[0062] The two side panels 11 are respectively provided with the fasteners 5 , and the opposite sides of the inner skeleton 2 are respectively used for movably connecting with the two side panels 11 through the connecting members 4 .

[0063] In this embodiment, springs and bolts are respectively provided on both sides of the inner skeleton unit 21 (on both sides close to the two side plates 11), so that the forces on both sides of the inner skeleton unit 21 are balanced and the structure is stable.

[0064] Among them, the spring is arranged between the side plate 11 and the inner skeleton unit 21, rather than between the bottom plate 12 and the inner skeleton unit 21. In this way, after the two ends of the spring are respectively inserted into the first slot and the second slot, when the bolts are not tightened to lock the inner skeleton unit 21, the inner skeleton unit 21, the spring, and the outer skeleton shell 1 will not be accidentally separated.

[0065] See also Figure 3 Optionally, an operation hole 121 is provided on the side of the exoskeleton shell 1 opposite to the first opening 13 .

[0066] In this embodiment, an operating hole 121 is provided on the side of the exoskeleton shell 1 opposite to the first opening 13, that is, on the bottom plate 12, and each inner skeleton unit 21 corresponds to an operating hole 121. The operating space provided by the operating hole 121 can be used to apply external force to the inner skeleton unit 21 inside the exoskeleton shell 1, thereby adjusting the amount by which the wiper strip 3 extends out of the first opening 13, and finally adjusting the interference amount between the wiper strip 3 and the windshield.

[0067] After the wiper frame is assembled, the wiper rubber strip 3 can be adjusted before being assembled with the wiper arm. For example, the adjustment can be performed by the following method:

[0068] First loosen the bolts, then stick the wiper strip 3 installed on the entire wiper frame to the contoured tooling of the windshield, as shown in the figure. Figure 4-Figure 5 As shown, the external auxiliary pressing mechanism 6 applies force to each inner frame unit 21 through the operating space provided by the operating hole 121, so that each inner frame unit 21 drives the wiper rubber strip 3 to be close to the contoured tooling 7, and the auxiliary pressing mechanism 6 adjusts the pressing force applied to the inner frame unit 21 at the corresponding position so that the interference amount of the wiper rubber strip 3 at the position of each inner frame unit 21 is within a reasonable range, and finally the bolts are tightened;

[0069] Among them, such as Figure 4-Figure 5As shown, the auxiliary clamping mechanism 6 includes a base plate and a plurality of auxiliary clamping units connected to the base plate, and the plurality of auxiliary clamping units correspond one to one with the plurality of inner skeleton units 21. The base plate may be an arc-shaped plate, and its curvature may be consistent with the curvature of the contour tooling 7. The axes of the plurality of auxiliary clamping units are respectively located on the radius of the circle where the base plate is located. In this way, the clamping force provided by the auxiliary clamping unit is respectively perpendicular to the tangent of the corresponding position of the contour tooling 7, and then the plurality of clamping forces provided by the plurality of auxiliary clamping units will make the shapes presented by the plurality of inner skeleton units 21 match the contour tooling 7, and finally realize that the curvature of the wiper strip 3 connected by the plurality of inner skeleton units 21 is consistent with the curvature of the contour tooling 7; of course, the adjustment of each inner skeleton unit 21 can also be adjusted manually through the space provided by the operating hole 121, and the curvature of the wiper strip 3 can also be achieved so that the curvature is consistent with the curvature of the contour tooling 7, while at the same time being within a reasonable interference range.

[0070] It should be noted that the profiling tool 7 is a profiling product of the windshield, and the outer skeleton shell 1 can be Figure 1 、 Figure 3 and Figure 4 The straight strip structure shown can also be as follows Figure 5 The strip-shaped structure with a certain curvature shown does not affect the angle adjustment between adjacent inner skeleton units 21 , so that the curvature of the wiper rubber strip 3 is consistent with the curvature of the contoured tooling 7 .

[0071] Another embodiment of the present invention further provides a wiper blade, comprising a wiper rubber strip 3 and the wiper frame as described above, wherein the wiper rubber strip 3 is mounted on the inner frame 2 of the wiper frame.

[0072] Since the technical improvements and beneficial effects of the wiper are the same as those of the wiper frame, the wiper will not be described in detail.

[0073] Yet another embodiment of the present invention provides a vehicle, comprising the wiper as described above.

[0074] Since the technical improvements and beneficial effects of the vehicle are the same as those of the wiper, no further details will be given on the vehicle.

[0075] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0076] Although the present invention is disclosed as above, the scope of protection disclosed by the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the scope of protection of the present invention.
