Description

Technical Field

[0001] The present invention relates to the technical field of traffic vehicle accessories, in particular to a windshield wiper. Background Art

[0002] Wipers are widely used in the field of transportation vehicles. They can play an important role in cleaning the windshield, thereby ensuring the driver's vision and being an important guarantee for safe driving.

[0003] The wipers currently on the market are usually composed of a rubber strip, two curved steel sheets, an interface seat, a spoiler and an end cover. The rubber strip is clamped on the steel sheet through the gap between the two steel sheets. The bottom of the interface seat is provided with a fixing groove for installing the steel sheet. The fixing groove extends along the length direction of the interface seat, and there are two fixing grooves corresponding to the number of steel sheets. The two fixing grooves are located on both sides of the interface seat. The interface seat is connected to the wiper control structure provided on the car through a connecting structure. Therefore, a connecting column for installing the connecting structure is usually provided on the top of the interface seat. The interface seat is installed in the middle of the steel sheet, and the interface seat is fixed between the two steel sheets at the same time.

[0004] When processing and assembling various structures, in order to achieve the connection and fixation between the interface seat and the steel sheet, the existing interface seat is usually pre-processed with mounting holes. When fixing the interface seat and the steel sheet, the steel sheet is first assembled on the interface seat, and then the two are connected and fixed together through the mounting holes to ensure the stability of the structure.

[0005] However, since the existing mounting holes are usually set away from the central axis of the interface seat, that is, the mounting holes are set beside the connecting column, rather than directly below the connecting column, this is mainly because the connecting column is extended along the width direction of the wiper. If the mounting holes are set directly below the connecting column, they will be blocked by the connecting column. On the one hand, it is extremely inconvenient to process the mounting holes. On the other hand, when the steel sheet and the interface seat are assembled and fixed, it will be difficult or even impossible to fix the steel sheet and the interface seat together through the mounting holes.

[0006] In this way, the steel sheet and the interface seat are assembled and fixed through the eccentric mounting hole, so that after the steel sheet is assembled on the interface seat, the mounting hole is deviated from the highest point of the steel sheet. This also means that the interface seat cannot exert force on the highest point of the steel sheet, making it easy for the two ends of the steel sheet to be subjected to uneven force during the use of the wiper, resulting in instability of the steel sheet structure, which in turn affects the friction effect of the rubber strip on the glass, and even destroys the overall stability of the wiper, affecting the use effect of the wiper. Summary of the Invention

[0007] The present invention aims to provide a wiper blade to solve the problem that the existing wiper blade has uneven force at both ends and unstable steel blade structure due to eccentric fixation.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a wiper, including a rubber strip, a spoiler wing, an end cover, an interface seat and a curved steel sheet, the interface seat including a detachably connected fixing seat and a connecting seat, the fixing seat is provided with a mounting hole and a fixing groove for installing the steel sheet, the fixing seat is fixedly connected to the highest point of the steel sheet through the mounting hole, and a connecting column extending along the width direction of the wiper is provided on the top of the connecting seat, and the connecting column is located directly above the mounting hole.

[0009] The principle and advantages of this solution are as follows: the interface seat is designed as a detachably connected fixing seat and connecting seat. When assembling the wiper, after the steel sheet is assembled into the fixing groove on the fixing seat, since the connecting seat has not yet been connected and installed, the mounting hole is not blocked by the connecting column or other structures. Therefore, the fixing seat and the steel sheet can be easily fixed through the mounting hole, thereby achieving fixation between the fixing seat and the highest point of the steel sheet. After the steel sheet is fixed, the connecting seat is installed on the fixing seat and connected and fixed to the fixing seat, thereby completing the assembly of the interface seat and achieving the installation of the connecting column.

[0010] By adopting the structure in this solution, the fixing operation of the steel sheet will not be hindered by the connecting column or other structures, so that the fixed connection between the interface seat and the highest point of the steel sheet can be achieved more conveniently, thereby making the force on both ends of the steel sheet uniform and stable, thereby improving the stability of the steel sheet structure and the wiper structure.

[0011] Preferably, as an improvement, a connecting assembly is provided between the fixing seat and the connecting seat, and the connecting assembly includes a hook and a slot that fit together for snap-fitting, one of the hook and the slot is provided on the fixing seat, and the other is provided on the connecting seat.

[0012] The connecting assembly is used to realize a detachable fixed connection between the fixing seat and the connecting seat. Compared with other detachable connection structures, this snap-on structure is simpler to process and the installation operation of the wiper is more convenient.

[0013] Preferably, as an improvement, the hook and the slot are both L-shaped, and the notch of the slot has a margin distance that allows the hook to withdraw from the slot; a locking assembly is also provided between the fixed seat and the connecting seat, and the locking assembly includes a locking protrusion and a locking groove that fit together, and one of the locking protrusion and the locking groove is provided on the fixed seat, and the other is provided on the connecting seat.

[0014] An L-shaped hook and slot are used to connect and fix the fixing seat and the connecting seat. Due to its curved structure, the hook has a certain effect of preventing it from falling out of the slot. At the same time, the setting of the locking assembly further ensures the stability of the connection between the fixing seat and the connecting seat.

[0015] Preferably, as an improvement, the side edge of the locking protrusion is provided with a first wedge surface and a first plane facing each other, and the groove wall of the locking groove is provided with a second wedge surface that abuts the first wedge surface and a second plane that abuts the first plane, the second wedge surface is opposite to the second plane, the first wedge surface and the second wedge surface, the first plane and the second plane are distributed along the length direction of the slot, and the first wedge surface and the second wedge surface are located on the side where the end of the transverse section of the slot is located, and the first plane and the second plane are located on the side where the end of the transverse section of the slot is connected to the longitudinal section.

[0016] The first wedge surface and the second wedge surface are located on the side where the transverse section of the slot is located, and the first plane and the second plane are located on the side where the transverse section of the slot is connected to the longitudinal section. The first wedge surface and the second wedge surface, and the first plane and the second plane, mutually abut against each other to achieve locking of the connecting assembly. When the hook attempts to slide out of the slot, the first plane and the second plane are located on the side where the transverse section of the slot is connected to the longitudinal section. The mutual abutment between the first plane and the second plane will prevent the hook from sliding. When the first wedge surface and the second wedge surface attempt to slide relative to each other, the first wedge surface and the second wedge surface are located on the side where the transverse section of the slot is located. The first wedge surface and the second wedge surface abut against each other to prevent relative sliding of the first wedge surface and the second wedge surface. This allows the locking assembly and the connecting assembly to be mutually locked, thereby enhancing the stability of the connection between the connecting seat and the fixing seat.

[0017] Preferably, as an improvement, the connecting assembly is arranged on the side of the interface seat, one of the locking protrusion or the locking groove is arranged on the top of the fixing seat, and the other is arranged on the bottom of the connecting seat.

[0018] Through this solution, the connecting component and the locking component are set separately, and the assembly of the connecting component is performed horizontally, while the assembly of the locking component is performed vertically. As a result, when assembling the wiper, both components can be effectively assembled separately to ensure effective connection of the structure.

[0019] Preferably, as an improvement, the rubber strip includes a mounting portion, a connecting portion and a scraping blade portion connected in sequence from top to bottom, and there is a gap between the mounting portion and the connecting portion to form a mounting groove for installing the steel sheet, and there is a gap between the connecting portion and the scraping blade portion to form a swinging groove for swinging the scraping blade portion, and the side surface of the connecting portion is a plane or a curved surface protruding outward.

[0020] The traditional rubber strip structure is as shown in the instructions. Figure 9As shown, the wiper comprises a mounting portion, a connecting portion, and a scraping blade. The side of the connecting portion is provided with a groove, which causes the lower portion of the connecting portion to protrude to form a support arm. A gap exists between the support arm and the scraping blade, forming a swinging zone. The groove on the side of the connecting portion serves as a buffer groove for the scraping blade to swing and cushion. Thus, the rubber strip is provided with at least three groove structures, namely, a mounting groove, a buffer groove, and a swinging groove for at least a steel sheet. The large number of grooves causes airflow to enter these grooves and generate vortices when the wiper is in use, emitting a loud noise. This wind noise is particularly pronounced when the vehicle is traveling at high speeds. Furthermore, when the vehicle is traveling at high speeds, the protruding support arm will vibrate violently due to the impact of the airflow, thereby generating a vibrating noise.

[0021] The rubber strip in this solution has significantly improved its tensile and compression permanent deformation properties due to the inventor's improvements and innovations to the material of the rubber strip. This effectively improves the rubber strip's resistance to permanent deformation. At the same time, the rubber strip's ability to recover after being compressed or stretched is also enhanced. Therefore, the rubber strip structure does not require an additional buffer zone to cushion the scraping edge. Therefore, the side surfaces of the connecting portion in this solution are flat or outwardly convex, meaning that the side surfaces of the connecting portion are not provided with holes or grooves. Furthermore, there are no protruding structures on the connecting portion, thereby omitting the buffer groove and support arm structures. This reduces wind noise and vibration noise during use, resulting in better practical performance. Furthermore, the rubber strip structure in this solution is simpler than that of existing rubber strips, reducing processing costs.

[0022] Preferably, as an improvement, the bottom surface of the connecting portion is a plane or an upwardly inclined surface.

[0023] The bottom surface of the connecting portion is a plane or an upwardly inclined surface, thereby increasing the width of the buffer groove and allowing the scraping blade to swing more widely, which is more conducive to frictional contact between the scraping blade and the vehicle windshield.

[0024] Preferably, as an improvement, lugs are provided on both sides of the upper portion of the connecting portion, and the edges of the lugs are flush with the edges of the mounting portion.

[0025] The design of the lugs allows the rubber strips to be installed in the gaps between the steel sheets so that both ends can have better contact with the steel sheets, thereby facilitating improved installation stability of the rubber strips.

[0026] Preferably, as an improvement, the surface of the spoiler wing is provided with a fluorine-containing coating, and the thickness of the fluorine-containing coating is 0.1 mm.

[0027] In this solution, a fluorine-containing coating is applied to the spoiler, preventing the spoiler from collecting large amounts of dust, resulting in a self-cleaning effect and improved practicality. The fluorine-containing coating is only 0.1mm thick, which is relatively thin and does not affect the fluid dynamics of the spoiler.

[0028] Preferably, as an improvement, the protective cover is fixedly connected to the interface seat and covers the interface seat, a latching protrusion is provided on the inner wall of the protective cover, a latching hole is provided on the side wall of the connecting seat, the latching protrusion is inserted into the latching hole, and a groove is provided at the front end of the protective cover to make way for the spoiler wing, and an opening is provided at the top of the protective cover, and the opening is located directly above the connecting column.

[0029] The protective cover in this solution shields and protects the interface socket, preventing dust accumulation inside and improving the wiper's aesthetics. The protrusions inside the protective cover engage with the holes on the connector, allowing the cover to be assembled, facilitating assembly of the structure. A recessed slot is provided at the front of the protective cover to allow for the spoiler to be positioned, preventing interference with its installation. The top of the protective cover features an opening directly above the connecting post, facilitating installation and use of the connecting structure attached to the post.

[0041] Example 1

[0042] The wiper in this embodiment has a structure as follows Figure 1 and Figure 2 As shown together, it includes a rubber strip 1, a spoiler wing 2, an end cover 3, an interface seat 5 and a curved steel sheet 11, wherein the spoiler wing 2, the end cover 3 and the steel sheet 11 are two groups with the same structure.

[0043] The interface seat 5 includes a detachable fixed seat 6 and a connecting seat 7, combined with Figure 3 and Figure 4 As shown in the figure, the fixing base 6 is provided with a mounting hole 8 and a fixing groove 9 for mounting the steel sheet 11. The fixing base 6 is fixedly connected to the highest point of the steel sheet 11 through the mounting hole 8. In this embodiment, the two are connected by welding. Figure 2 As shown, a connecting column 10 extending along the width direction of the wiper is provided on the top of the connecting seat 7, and the connecting column 10 is located just above the mounting hole 8. A connecting assembly is provided between the fixing seat 6 and the connecting seat 7. Figures 3 to 5 As shown together, the connecting assembly includes a hook 12 and a slot 13 that engage with each other. One of the hook 12 and the slot 13 is provided on the fixing base 6, and the other is provided on the connecting base 7. In this embodiment, the hook 12 is provided on the connecting base 7, and the slot 13 is provided on the fixing base 6. In actual application, the hook 12 can also be provided on the fixing base 6, in which case the slot 13 is correspondingly provided on the connecting base 7. The hook 12 and the connecting base 7 are integrally formed, and in this embodiment, the hook 12 and the slot 13 are both L-shaped. The notch of the slot 13 has a margin distance that allows the hook 12 to withdraw from the slot 13. In addition, the connecting assembly in this embodiment is provided on the side of the interface base 5.

[0044] A locking assembly is further provided between the fixing base 6 and the connecting base 7. The locking assembly includes a locking protrusion 15 and a locking groove 16 that engage with each other. One of the locking protrusion 15 and the locking groove 16 is provided on the fixing base 6, and the other is provided on the connecting base 7. One of the locking protrusion 15 or the locking groove 16 is provided at the top of the fixing base 6, and the other is provided at the bottom of the connecting base 7. The locking protrusion 15 in this embodiment is arranged at the bottom of the connecting seat 7 and protrudes from the bottom surface of the connecting seat 7. The side edge of the locking protrusion 15 is provided with a first wedge surface 17 and a first plane 18 facing each other. The locking groove 16 is provided at the top of the fixing seat 6, and the groove wall of the locking groove 16 is provided with a second wedge surface 19 that abuts against the first wedge surface 17 and a second plane 20 that abuts against the first plane 18. The second wedge surface 19 is opposite to the second plane 20. The first wedge surface 17 and the second wedge surface 19, the first plane 18 and the second plane 20 are distributed along the length direction of the card slot 13, and the first wedge surface 17 and the second wedge surface 19 are located on the side where the end of the transverse section of the card slot 13 is located, and the first plane 18 and the second plane 20 are located on the side where the transverse section and the longitudinal section of the card slot 13 are connected.

[0045] When assembling the wiper blade in this embodiment, Figure 1 or Figure 2 As shown, two steel sheets 11 are inserted into the fixing grooves 9 of the fixing base 6, and the highest point of the steel sheet 11 is aligned with the mounting hole 8 on the fixing base 6. Then, solder is used to weld the fixing base 6 and the steel sheet 11 together through the mounting hole 8, thus achieving a fixed connection between the fixing base 6 and the steel sheet 11. Figure 7 As shown, the spoiler 2 is placed on the outside of the steel sheet 11. The steel sheet 11 is then aligned with the steel sheet 11 mounting groove 28 on the rubber strip 1. The rubber strip 1 is then slid into the gap between the two steel sheets 11, so that the two steel sheets 11 stably clamp and secure the rubber strip 1. The two end caps 3 are then clamped and secured to the ends of the steel sheets 11, so that the end caps 3 bring the ends of the two sets of steel sheets 11, the ends of the rubber strip 1, and the ends of the spoiler 2 together and secure them together.

[0046] Recombination Figures 2 to 5 As shown, the hook 12 on the connecting base 7 is aligned with the slot 13 on the fixing base 6 and slid from the notch of the slot 13 into the slot 13 so that the end of the hook 12 abuts against the end of the slot 13. At this time, the connecting base 7 and the fixing base 6 are fixed together. To ensure the stability of the connection between the connecting base 7 and the fixing base 6, when the hook 12 is inserted, the locking protrusion 15 at the bottom of the connecting base 7 is aligned with the locking groove 16 at the top of the fixing base 6. The connecting base 7 is pressed downward so that the locking protrusion 15 is engaged with the locking groove 16, causing the first wedge surface 17 to abut against the second wedge surface 19, and the first flat surface 18 to abut against the second flat surface 20. This achieves a two-stage fixing between the connecting base 7 and the fixing base 6, thereby enhancing the stability of the connection between the two.

[0047] Afterwards, the connecting structure is clamped on the connecting column 10 on the top of the connecting seat 7. The connecting structure in this embodiment is connected using a connector 14, and an arc groove is provided on the connector 14. When assembling the connector 14, the connector 14 can be installed and fixed by clamping the connecting column 10 on the connecting seat 7 into the arc groove.

[0048] During the assembly process of the wiper, since the interface seat 5 is a detachable connecting seat 7 and fixing seat 6 structure, when installing the steel sheet 11, the mounting hole 8 is in an unobstructed state, so the highest point of the steel sheet 11 and the fixing seat 6 can be conveniently welded and fixed through the mounting hole 8. After the fixation of the steel sheet 11 is completed, the connecting seat 7 is assembled on the fixing seat 6. In this way, the position of the connecting column 10 is directly above the highest point of the steel sheet 11, so it will not affect the connection between the wiper and the wiper control structure on the vehicle, so that when the wiper is in use, the force on both ends of the steel sheet 11 is more uniform and stable, thereby improving the stability of the wiper during use.

[0049] The connecting assembly and the locking assembly between the connecting seat 7 and the fixing seat 6 prevent the connection between the connecting seat 7 and the fixing seat 6 from falling off and provide double reinforcement, thereby improving the stability of the structure of the interface seat 5.

[0050] Example 2

[0051] The difference between this embodiment and embodiment 1 lies in the structure of the rubber strip 1, as shown in FIG. Figure 8 As shown, the rubber strip 1 includes a mounting portion 24, a connecting portion 25 and a scraping portion 26 connected in sequence from top to bottom. The mounting portion 24, the connecting portion 25 and the scraping portion 26 in this embodiment are integrally formed and connected by a connecting bridge 27, and there is a gap between the two ends of the mounting portion 24 and the two ends of the connecting portion 25 to form a mounting groove 28 for mounting the steel sheet 11, and there is a gap between the two ends of the connecting portion 25 and the two ends of the scraping portion 26 to form a swinging groove 29 for the scraping portion 26 to swing.

[0052] The side surfaces of the connecting portion 25 are flat or outwardly convex curved surfaces, and the bottom surface of the connecting portion 25 is flat or upwardly inclined. Specifically, in this embodiment, the side and bottom surfaces of the connecting portion 25 are both flat, giving the connecting portion 25 a rectangular structure. In actual applications, the side and bottom surfaces are not limited to flat surfaces and can also be outwardly convex curved surfaces or upwardly inclined surfaces. Lugs 30 are provided on both sides of the upper portion of the connecting portion 25, and the edges of the lugs 30 are flush with the edges of the mounting portion 24.

[0053] In addition, the rubber strip 1 in this embodiment is made of natural rubber as the main raw material and is mixed with the following raw materials in parts by weight: 95-105 parts natural rubber, 4-6 parts zinc oxide, 0.5-1.5 parts stearic acid, 2-5 parts antioxidant, 10-50 parts carbon black, 4-10 parts softener, 1.5-2.5 parts accelerator, 0.3-3 parts vulcanizer, 1-2 parts dispersing flow agent, 1-20 parts cerium oxide, and 1-30 parts bismuth oxide. The addition of cerium oxide and bismuth oxide combines with different molecular chain groups of natural rubber, and the molecular chains intersect to form a composite network structure. The bonding strength at the molecular chain level is extremely high, which is reflected in the material performance by significantly reducing both tensile and compression set. As a result, after a period of use, the wiper strip has strong resistance to permanent deformation and strong recovery ability after compression or stretching. The service life of the wiper strip is also increased from 500,000 times to approximately 1.3 million times.

[0054] Due to the improvement in the material of the rubber strip 1, the rubber strip 1 does not need to be additionally designed with a buffer zone to buffer the scraping blade portion 26, and the connecting portion 25 is designed to be a flat surface without grooves on the side or a curved surface structure protruding outward. This embodiment is a flat structure, that is, the side of the connecting portion 25 is not provided with a slot structure. Furthermore, there is no protruding support arm 31 on the connecting portion 25. As a result, the structure of the buffer groove 32 and the support arm 31 is omitted, thereby reducing wind noise and vibration noise during use, and improving practical performance. The bottom surface of the connecting portion 25 is a flat surface or an upwardly inclined surface, thereby increasing the width of the buffer groove 32, allowing the scraping blade portion 26 to swing to a greater extent, which is more conducive to frictional contact between the scraping blade portion 26 and the vehicle windshield. In addition, the rubber strip 1 structure in this solution is simpler than the existing rubber strip 1 structure, and the processing cost can also be reduced.

[0055] Example 3

[0056] The difference between this embodiment and the above embodiment is that it further comprises a protective cover 4, which is fixedly connected to the interface seat 5 and covers the interface seat 5. Figure 6 As shown, the inner wall of the protective cover 4 is provided with a latching protrusion 21, and the side wall of the connecting seat 7 is provided with a latching hole 22. The latching protrusion 21 is locked into the latching hole 22. In this embodiment, there are two corresponding sets of latching protrusions 21 and latching holes 22. The cooperation between the two sets of latching protrusions 21 and latching holes 22 ensures a more stable connection between the protective cover 4 and the connecting seat 5. A clearance groove 23 is also provided at the front end of the protective cover 4 to allow for the top of the spoiler 2 to pass. The top of the protective cover 4 also has an opening, located directly above the connecting post 10, thereby exposing the connecting post 10 and facilitating the installation and use of the connecting structure connected to the connecting post 10.

[0057] When assembling the protective cover 4, place the protective cover 4 over the outside of the interface seat 5 and the connecting structure, snap the protrusions 21 in the protective cover 4 into the snap holes 22 on the connecting seat 7, and at the same time, insert the ends of the spoiler wings 2 into the clearance grooves 23 on the protective cover 4. This completes the assembly of the protective cover 4.

[0058] Example 4

[0059] The difference between this embodiment and the previous embodiment is that a fluorine-containing coating is provided on the surface of the spoiler wing 2. The thickness of the fluorine-containing coating is 0.1 mm.

[0060] The fluorine-containing coating in this embodiment prevents the spoiler wing 2 from being stained with a large amount of dust, thereby achieving a self-cleaning effect and improving practicality. The fluorine-containing coating is only 0.1 mm thick, which is relatively small and does not affect the fluid dynamics effect of the spoiler wing 2.

[0061] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
