Description

Technical Field

[0001] This invention relates to the field of automotive wiper blades, and more particularly to a noise-reducing wiper blade and its processing method. Background Technology

[0002] In automotive products, windshield wipers are an indispensable and crucial component, primarily used to wipe and clean the windshield, providing the driver with excellent visibility. The wiper blade is a vital part of the wiper system. When the wiper blade moves in one direction with the wiper arm, it is subjected to the combined effects of lateral friction from the windshield and the thrust of the wiper arm, causing it to elastically bend and deform along the direction of movement. However, when the wiper reaches the end of its travel and changes direction (i.e., the moment of reversal), the direction of lateral friction on the wiper blade is synchronously reversed from the direction of the drive force of the wiper arm, causing the direction of bending deformation of the wiper blade to rapidly switch—from bending in the forward direction of the original movement to bending in the reverse direction. At this moment, the contact state between the wiper blade and the windshield changes from uniform adhesion to a sudden change in localized contact pressure, resulting in periodic, high-frequency fluctuations in the friction between them. These frictional fluctuations trigger high-frequency vibrations between the wiper blade and the windshield surface, and the vibrational energy propagates through the air, creating high-frequency frictional noise that is clearly perceptible to the human ear. Because of the reciprocating motion of the windshield wipers between the two ends of their travel, when the wiper reaches the end of its travel and reverses direction, the wiper blade will flip from one direction to the other, causing continuous impact noise between the wiper blade and the glass, which greatly affects the experience of the occupants of the vehicle. Summary of the Invention

[0003] The present invention aims to solve the above problems and provides a noise-reducing wiper blade and a processing method thereof.

[0004] To address the aforementioned problems, the present invention provides a noise-reducing wiper blade, comprising a rubber blade body and at least one support member, wherein the support member is disposed within the rubber blade body to reduce the noise generated by the rubber blade body when wiping glass by increasing the strength of the rubber blade body.

[0005] Furthermore, multiple support members are provided, and the multiple support members are arranged at intervals along the length direction of the adhesive strip body;

[0006] or

[0007] One support member is provided, which is located at the position of the adhesive strip body for bearing the force from driving the adhesive strip body to reciprocate and scrape.

[0008] Furthermore, the support member extends along a first direction in which the wiper blade is upright relative to the glass.

[0009] Furthermore, the support member extends along the first direction from the end of the adhesive strip body opposite to the end in contact with the glass to the end of the adhesive strip body in contact with the glass;

[0010] or,

[0011] The support extends from the end of the adhesive strip body opposite to the glass contact point along the first direction into the interior of the adhesive strip body.

[0012] Furthermore, the support members are evenly distributed along the length direction of the adhesive strip body.

[0013] Furthermore, the structural stiffness of the support member is greater than the structural stiffness of the adhesive strip body.

[0014] Furthermore, the support member is disposed on the structural symmetry plane of the adhesive strip body.

[0015] Furthermore, the adhesive strip body includes a skeleton portion and a sealing lip portion, the skeleton portion and the sealing lip portion are integrally formed, and the sealing lip portion is disposed on opposite sides of the skeleton portion;

[0016] The support member is located inside the skeleton.

[0017] Furthermore, the present invention also provides a method for processing a noise-reducing wiper blade, characterized in that it includes:

[0018] S1. Provide a base material and at least one support member, wherein the stiffness of the support member is higher than that of the base material;

[0019] S2. The base material and the support member are compositely molded into an integrated structure through a molding process, wherein the base material forms the outer contour of the wiper blade, and the support member is integrated inside the base material to form an integrated noise-reducing wiper blade with the support member embedded inside.

[0020] Furthermore, the molding process is one of compression molding, injection molding, extrusion molding, or secondary assembly molding.

[0021] The beneficial contribution of this invention lies in its effective solution to the aforementioned problems. By incorporating a support member within the wiper blade body, this invention significantly reduces the degree of bending and deformation of the wiper blade when wiping glass.

[0025] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention. The following specific examples illustrate the implementation of this disclosure, and those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0026] like Figures 1 to 3 As shown, the key feature of the noise-reducing wiper blade of the present invention is that a support member 20 is provided inside the main body 10 of the wiper blade. The support member 20 is used to enhance the properties of the wiper blade—strengthening the wiper blade, so that the wiper blade is less likely to generate noise when the wiper changes direction, thereby achieving the effect of noise reduction.

[0027] Specifically, the noise-reducing wiper blade of the present invention includes a rubber strip body 10 and multiple support members 20. The rubber strip body 10 is the main structure of the wiper blade, which is connected to the wiper and used to directly wipe the glass surface to remove rainwater. The rubber strip body 10 typically has a certain degree of elasticity to fit more tightly to the glass and thus remove rainwater from the glass.

[0028] The support member 20 is disposed inside the adhesive strip body 10, and there is at least one of them. It can reduce the noise generated by the adhesive strip body 10 when it is scraping the glass by increasing the strength of the adhesive strip body 10.

[0029] The properties of the support member 20 are different from those of the rubber strip body 10. The support member 20 has a stronger resistance to deformation than the rubber strip body 10, making it less likely for the rubber strip body 10 to collapse during scraping and maintaining a relatively stable angle for scraping, thereby reducing the noise generated during reversal.

[0030] In layman's terms, the structural rigidity of the support member 20 is greater than that of the rubber strip body 10. The support member 20 is disposed inside the rubber strip body 10, acting as the longitudinal skeleton of the rubber strip body 10. This improves the overall longitudinal rigidity of the wiper blade, making the rubber strip body 10 less prone to deformation in both directions along its length. This significantly reduces the angle at which the rubber strip body 10 collapses during wiping, ensuring it remains relatively upright during reversal, or greatly reducing the difference in collapse angle before and after reversal. This allows the rubber strip body 10 to wipe in a relatively stable state, reducing noise generated during reversal. When the wiper blades are wiping back and forth at high speed, under the influence of inertia, the wiper blade is prone to generating significant impact noise at the moment of reversal. This is because the wiper blade is relatively soft and lies flat against the windshield surface during wiping. Under the influence of inertia, different parts may exhibit different movement trends during reversal, easily leading to significant impact noise. Specifically, the end directly connected to the wiper blade reverses direction more directly, while the part in contact with the glass reverses direction with a delay. Therefore, when reversing, the end directly connected to the wiper blade has already reversed direction, while the end in contact with the glass maintains its original movement trend due to inertia. This results in different movement trends in different parts of the wiper blade body 10, leading to significant impact noise. However, by incorporating a support member 20 within the wiper blade body 10, the elasticity of the wiper blade body 10 is not affected. The wiper blade body 10 can still adhere tightly to the glass surface to wipe away rainwater, but it increases the strength of the wiper blade, especially its rigidity. This makes the movement trends of different parts of the wiper blade more consistent when reversing, thus significantly reducing the impact noise generated when the wiper blade reverses direction, thereby achieving noise reduction.

[0031] In addition, since the support member 20 is provided inside the rubber strip body 10, the rubber strip body 10 is less likely to fall over on the glass surface. During the scraping process, the contact between the rubber strip body 10 and the glass surface is reduced, which also makes it easier to reduce the noise during scraping.

[0032] On the other hand, the support member 20 is set inside the rubber strip body 10, which can also prevent the wiper blade from generating high-frequency vibration or up-and-down shaking when wiping, increase structural rigidity, change the natural frequency, and reduce the resonance caused by the wiper blade friction with the glass and speed changes, thereby playing a role in noise reduction.

[0033] In some embodiments, one support member 20 is provided, and the support member 20 is disposed at a position on the rubber strip body 10 for bearing the force from driving the rubber strip body 10 to reciprocate. When the rubber strip body 10 is driven by the wiper to reciprocate, there is at least one connection point between the wiper and the rubber strip body 10, so that the rubber strip body 10 can be driven by the wiper to perform reciprocating wiping. The position where the wiper is connected to the rubber strip body 10 corresponds to the position on the rubber strip body 10, which is the position where the support member 20 is disposed. Of course, if there are two connection points between the wiper and the rubber strip body 10, support members 20 can be disposed at the corresponding positions of the two positions. When the wiper drives the rubber strip body 10 to swipe back and forth, force is applied to the rubber strip body 10. At this time, the rubber strip body 10 mainly relies on its joint to bear the force. By setting a support member 20 at the corresponding position of the joint, the rubber strip body 10 is less likely to deform or collapse at this point. In this way, other parts of the rubber strip body 10 are also less likely to deform or collapse, thus maintaining a relatively upright state and reducing the noise generated when changing direction. The position where the wiper connects to the rubber strip body 10 is usually located in the middle of the rubber strip body 10. Therefore, when there is only one support member 20, it is preferable to set it in the middle position of the rubber strip body 10.

[0034] In some embodiments, multiple support members 20 are provided, and the multiple support members 20 are arranged at intervals along the length direction of the rubber strip body 10. The interval arrangement of the support members 20 along the length direction of the rubber strip body 10 not only changes the strength of the rubber strip body 10 and reduces noise during reversal, but also does not hinder the bending of the rubber strip body 10 in its length direction, thereby allowing the rubber strip body 10 to adapt to the curvature of the windshield and effectively wipe away rainwater. Generally, the curvature of windshields varies among different vehicle models. The rubber strip body 10 has a certain degree of elasticity; in its natural state, it is bent with a certain arc. When it is pressed against the windshield by the wipers, the rubber strip body 10 conforms to the curvature of the windshield. The interval arrangement of the support members 20 ensures that the rubber strip body 10 retains its deformability in its length direction and can bend to varying degrees to adapt to windshields with different curvatures. If the support members 20 are arranged all along the length of the rubber strip body 10, it will affect the ability of the rubber strip body 10 to bend and deform along the length, making it impossible for the rubber strip body 10 to adapt to windshields with different curvatures. Therefore, multiple support members 20 are arranged at intervals along the length of the rubber strip body 10, which can reduce noise without affecting the curvature adaptability of the rubber strip body 10.

[0035] In addition, the support member 20 is provided inside the main body 10 of the wiper blade, which can improve the pressure distribution of the wiper blade, make the pressure of each part of the wiper blade uniform, avoid local deformation of the wiper blade, ensure the adhesion between the wiper blade and the glass surface, and thus ensure that the rainwater is wiped clean.

[0036] Furthermore, the support member 20 extends along a first direction in which the wiper blade is vertical relative to the glass. This first direction can be a straight line or a non-straight line. In other words, the support member 20 can be straight or non-straight. When the support member 20 is straight, it can be configured to be perpendicular to the length direction of the wiper blade body 10, or it can be configured to be inclined to the length direction of the wiper blade body 10. When the support member 20 is non-straight, it can be curved, wavy, or other shapes.

[0037] In addition, the support member 20 can be a long and thin strip or a thick block (i.e., the difference between length and width is not so obvious).

[0038] In summary, the shape of the support member 20 is not strictly limited, as long as it can enhance the overall strength of the adhesive strip body 10 and achieve the function described in this application.

[0039] Preferably, the support member 20 is configured as a long, thin strip, which is straight and positioned along the normal direction of the glass surface. When the wiper blade is attached to the glass surface, the wiper blade is vertical relative to the glass surface, and this vertical direction is the normal direction of the glass surface, which is the preferred orientation of the support member 20.

[0040] The length of the support member 20 can be set as needed.

[0041] In some embodiments, the support member 20 extends through the vertical direction of the rubber strip body 10, and extends from the end of the rubber strip body 10 opposite to the glass contact end along the first direction to the end of the rubber strip body 10 in contact with the glass. This embodiment is more convenient to process, facilitating the processing of the support member 20 into the wiper blade. In some embodiments, the support member 20 extends from the end of the rubber strip body 10 opposite to the glass contact end along the first direction into the interior of the rubber strip body 10.

[0042] When the support members 20 are distributed along the length direction of the rubber strip body 10, the spacing between them can be designed according to factors such as the strength of the support members 20 and the length of the wiper blade. Preferably, the support members 20 are evenly distributed along the length direction of the rubber strip body 10.

[0043] The structural stiffness of the support member 20 is greater than that of the adhesive strip body 10, so that the support member 20 can play a supporting and reinforcing role.

[0044] The material of the support member 20 can be set as needed. It can be a metal material or a rigid plastic. It can resist the elastic deformation of the rubber strip body 10 to a certain extent, so that the rubber strip body 10 is not prone to large different movement trends due to inertia when it turns back and changes direction.

[0045] Since the wiper blades swipe back and forth, to avoid affecting their original wiping ability, the support member 20 is located on the structural symmetry plane of the rubber strip body 10. In other words, when the support member 20 is distributed along the length of the rubber strip body 10, the rubber strip body 10 is symmetrically distributed with respect to the support member 20.

[0046] Furthermore, the adhesive strip body 10 includes a skeleton portion 11 and a sealing lip portion 12. The skeleton portion 11 and the sealing lip portion 12 are integrally formed and are made of an elastic material, possessing elasticity. Typically, the adhesive strip body 10 is made of silicone rubber.

[0047] The skeleton part 11 is the skeleton structure of the adhesive strip body 10. It provides the main strength of the adhesive strip body 10 and is used to uniformly transmit pressure along the length direction of the adhesive strip body 10, so that the adhesive strip body 10 can adhere to the glass surface for scraping, and avoid the adhesive strip body 10 bending and warping, which would lead to uneven scraping or missed scraping.

[0048] The sealing lips 12 are located on both sides of the frame portion 11 and are used for wiping or enhancing the wiping effect. The sealing lips are symmetrically distributed on both sides of the frame portion 11. The sealing lips have better elastic deformation capability than the frame portion 11, and can adapt to the curvature of the glass and bend in different directions, so that when the wiper blade slashes across the windshield with a complex curvature, the corresponding sealing lips 12 can independently and smoothly fit against the glass surface, eliminating vibration and noise caused by poor fit.

[0049] In this embodiment, four sealing lips 12 are provided on both sides of the skeleton part 11. The multiple sealing lips 12 can work together to break the water film on the glass surface in stages, effectively remove the residual thin water film and micro water droplets, and achieve a cleaning effect that is almost like dry scraping.

[0050] The multiple sealing lips 12 are spaced apart to form longitudinal drainage channels. During use, rainwater that is wiped away can be quickly guided through these channels to the sides for discharge, rather than accumulating in front of the wiper blade and forming a water wall. This effectively reduces water spray at high speeds and prevents water from seeping back into the wiped area. In addition, the design of the multiple sealing lips 12 also helps to streamline airflow and reduce aerodynamic lift during high-speed driving, ensuring that the wiper blade remains stably in contact with the glass.

[0051] When the adhesive strip body 10 is scraped on the glass surface, the end of the skeleton part 11 mainly contacts the glass surface. When the skeleton part 11 is tilted relative to the glass surface, part of the sealing lip part 12 contacts the glass surface.

[0052] Furthermore, the support member 20 is disposed in the skeleton part 11, and its stiffness is greater than that of the skeleton part 11.

[0053] When the support member 20 is disposed in the skeleton part 11, it can completely penetrate the skeleton part 11 along the first direction, or it can be embedded in the skeleton part 11 along the first direction.

[0054] Thus, the noise-reducing wiper blade of the present invention is formed, which includes a rubber strip body 10 and a support member 20. The support member 20 can improve the strength of the wiper blade, so that the wiper blade retains its original elasticity and can adhere to the glass surface for wiping, and can resist the inertial potential energy when turning back, thereby greatly reducing the impact noise generated when turning back.

[0055] The noise-reducing wiper blade of this invention has a simple structure and practical function, making it highly practical.

[0056] Furthermore, the present invention also provides a processing method for the above-mentioned noise-reducing wiper blade, which is manufactured through a molding process, specifically including the following steps:

[0057] S1. Provide a base material and at least one support member 20, wherein the stiffness of the support member 20 is higher than that of the base material;

[0058] S2. The base material and the support member 20 are compositely molded into an integrated structure through a molding process, wherein the base material forms the outer contour of the wiper blade, and the support member 20 is integrated inside the base material to form an integrated noise-reducing wiper blade with the support member 20 embedded inside.

[0059] In this embodiment, the molding process is a compression molding process, and step S2 specifically includes:

[0060] The matrix material is placed in the cavity of the molding die;

[0061] The support members 20 are arranged in the cavity of the molding die at predetermined intervals or at predetermined positions; when the support members 20 are arranged in the cavity of the molding die at predetermined intervals, the support members 20 are arranged at intervals along the length direction of the wiper blade.

[0062] The molding die is closed and heated and pressurized, so that the base material covers the support member 20 and fills the cavity in a molten and flowing state. After heat preservation and pressure preservation and curing, an integrated noise reduction wiper blade with the support member 20 embedded inside is formed.

[0063] Furthermore, the matrix material is rubber or thermoplastic elastomer, such as ethylene propylene rubber or chloroprene rubber, which has excellent weather resistance and ozone resistance, a heat resistance limit of over 100°C, and can still maintain good elasticity in a low temperature environment of -40°C.

[0064] The support member 20 is made of metal or rigid engineering plastic. For example, the support member 20 may be made of high carbon steel.

[0065] Furthermore, in the above steps, placing the base material in the cavity of the molding die and arranging the support member 20 at predetermined intervals or in predetermined positions in the cavity of the molding die are not necessarily in any particular order; the base material can be placed first, or the support member 20 can be placed first.

[0066] When the support members 20 are arranged at intervals along the length of the wiper blade, they are preferably arranged at uniform intervals, for example, at intervals of 2 cm.

[0067] When the support member 20 is arranged in the cavity of the molding die at a predetermined position, the support member 20 is located at the position of the wiper blade for bearing the force from driving the wiper blade to reciprocate. It is usually located at the middle position along the length direction.

[0068] After the base material and support member 20 are placed in the corresponding molding die as required, the molding die can be closed and heated and pressurized. The base material melts and fills the cavity, while the support member 20 is pre-placed in the cavity. Therefore, the base material will wrap around the support member 20. When the base material solidifies, it forms the rubber strip body 10, and the support member 20 is wrapped inside the rubber strip body 10, thereby forming an integrated noise-reducing wiper strip.

[0069] Furthermore, the heating temperature of the molding die is 150℃~180℃, the pressure is 10MPa~15MPa, and the heat and pressure holding time is 5min~15min.

[0070] Furthermore, the molding die is provided with a positioning mechanism to ensure that the support member 20 maintains a predetermined interval and position within the cavity.

[0071] In some other embodiments, the molding process may also be an extrusion molding process, in which case step S2 specifically includes:

[0072] The support member 20 is fed into the die head cavity of the extruder as an inner core;

[0073] Start the extruder so that the molten matrix material passes through the die under pressure and continuously coats the outer surface of the support 20.

[0074] After cooling, shaping and curing, the wiper blade is cut to a predetermined length to form an integrated noise-reducing wiper blade with the support member 20 embedded inside.

[0075] In some other embodiments, the molding process may also be a secondary assembly process. In this case, step S2 specifically includes:

[0076] First, the base material is processed into a rubber strip body with a preset cross-sectional shape. The rubber strip body has at least one reserved hole; this reserved hole is used for the subsequent installation of the support member 20. The number of reserved holes is set as needed, and can be one or more. When a single reserved hole is provided, it is located at a position to withstand the force from the reciprocating wiping of the wiper blade, typically at the middle position along the length direction. When multiple reserved holes are provided, they are spaced apart along the length direction of the rubber strip body. The reserved hole can be a blind hole or a through hole. Preferably, it is a blind hole.

[0077] The support member 20 is pushed into the body of the adhesive strip along the reserved hole; in this step, a mechanical pushing device or a pulling device can be used to push the support member 20 into the body of the adhesive strip.

[0078] End caps are installed at both ends of the pre-drilled hole or sealed by heat fusion to limit the displacement of the rod-shaped support 20 inside the main body of the wiper blade. This process produces an integrated noise-reducing wiper blade with the support 20 embedded inside.

[0079] In this embodiment, the support member 20 can be a thin metal rod or a rigid plastic rib, etc.

[0080] In some other embodiments, the support member 20 can be fixed in the mold cavity first, and then molten matrix material can be injected into the cavity using an injection molding machine to cover the support member 20. After the matrix material solidifies, an integrated noise-reducing wiper blade with the support member 20 embedded inside can be processed. In some other embodiments, half of the main body of the wiper blade can be processed from the matrix material first, and then the support member 20 can be placed between the two structures. The two structures can be joined together by hot pressing or molding, thereby covering the support member 20 inside the main body of the wiper blade, thus processing an integrated noise-reducing wiper blade with the support member 20 embedded inside.

[0081] After the aforementioned different process steps are completed, the support member 20 is covered inside the rubber strip body. The support member 20 can be fully covered or partially covered. When the support member 20 is partially covered, the uncovered part is cut off so that the support member 20 of the wiper blade is fully covered inside the rubber strip body.

[0082] Preferably, in this application, the support member 20 and the base material are molded together to form the wiper blade. This structure is firmly bonded and can firmly combine two materials with different properties, thus avoiding failure.

[0083] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
