JP3160871U - Flat blade wiper for vehicle - Google Patents

Abstract

When a wiper swings back and forth, while removing jerking, the working force is directly transmitted to a clipping sleeve mount by a metal keelson strip without any stop or delay, and noise that impairs the quietness of the interior of the vehicle. Prevent it from occurring. A flat blade wiper for a vehicle is a slender scraping blade having a rigid and elastic metal keelson strip (20), a saddle bracket (30) for receiving a wiper adapter (70), and an upper wing (51). (50) Includes two rigid rigid clipping sleeve mounts (40) and a pair of end positioning caps (60). Each clipping sleeve mount and wiper adapter saddle bracket each have a first common receiving channel and a second receiving channel, so that the elastic metal keelson strip can penetrate the first receiving channel. The upper wing of the elongated scraping blade can penetrate the second receiving channel of both the wiper adapter saddle bracket and the clipping sleeve mount. [Selection] Figure 8

Description

  The present invention relates to a flat blade wiper that can transmit an acting force directly to a clipping sleeve mount by a metal keelson strip without any stop or delay and jerking when the wiper swings back and forth. In addition, the alignment of the main components of the wiper can be achieved without great care, which can significantly reduce the fatigue of the assembly operator. Therefore, not only can assembly time be saved, but also the assembly efficiency is increased. As a result, manufacturing costs decrease and market competitiveness increases.

  The evolution of vehicle windshield wipers is usually from the traditional “frame-supported wipers” to the latest “non-framed wipers” known colloquially as “flat blade wipers”. A “frame-supported wiper” is a U-shaped metal blade frame, commonly referred to as a metal blade frame that serves as an exposed support keel for the associated rubber blade, with a slot along the length of the frame to hold the rubber blade. A flat metal strip for a “non-framed wiper”, which includes a metal strip, is fitted into a flexible elastic clipping sleeve sheath that substantially holds the rubber blade and is coated for the associated rubber blade. Work as Kielson. In recent years, most windshield wipers included in newly marketed vehicles have been “non-framed wipers”. “Frame-supported wipers” are apparently declining gradually from the market, because “frame-supported wipers” are used with heavier weight, more components and more power consumption. This is because there is a greater possibility of corrosion caused by jerking noise due to rocking friction against the windshield after time and exposure of the exposed metal blade frame to the outside air. In addition, windshield wipers belong to consumable products and require replacement when reduced wiper wiping due to aging may affect driving safety. A large number of accumulated bad wipers of the “frame supported wiper” type that is replaced every year is a heavy burden on the environment. In contrast, “non-framed wipers” do not cause such a burden on the environment.

  Accordingly, US utility patents US6523218, US6944905, US72222888, US70555206, US7305334, US7484264, and US7210189, and US design patent Des. Various “non-framed wipers” as described in 430097, D512362, D457479, D443854, D511735, D564434S, D564955S, D579401S, and D579849S are very well developed. Among these “non-framed wipers” referred to above, US Pat. No. 7,210,189 discloses a state-of-the-art “non-framed wiper” shown in FIGS. 1 to 6 of the present application. As described in “Detailed Description of Preferred of the Present Invention” in US Pat. No. 7,210,189, a windshield wiper has two blade bodies 6, a rectangular cross section. It comprises a flat metal vertebra 7, a rubber element 9 and a central support 10.

  The blade body 6 includes a flexible upper support 4 and a semi-rigid lower support 5. By joining the upper support 4 and the lower support 5 by co-extrusion, one piece of them ensures an integral support for the other components of the blade system including the metal spine 7 and the rubber element 9, said upper support 4 includes a mounting channel 8 that passes longitudinally over the length of the blade body 6 and is preferably rectangular in shape, the mounting channel 8 also preferably having a rectangular flat profile and shape and A metal spine 7 is inserted which is used to ensure and maintain a uniform contact of the element 9 to the windshield 3, the lower support 5 passing over the length of the blade body 6 and preferably in shape. Includes a lower mounting channel 12 which is rectangular and further comprises a longitudinal rectangular opening 13 extending over the blade body 6, The body 5, the rectangular top 16 having a central neck of the rubber element 9 is inserted through the lower mounting channel 12 and the longitudinal rectangular opening 13 (as shown in FIGS. 1 to 3), and

  The central support 10 made of metal or plastic material and adapted to the adapter of the wiper arm 2 of the windshield wiper 3 comprises an upper mounting channel 11 and a lower passage channel 14, the upper mounting channel 11 being a central support 10 passes longitudinally over the length of 10 and is preferably rectangular in shape, into which the metal spine 7 is inserted, the passage channel 14 extending longitudinally over the length of the central support 10 The lower part further comprises a longitudinal rectangular opening 15 which passes and preferably is rectangular in shape and extends over the continuous central support 10 so that the rectangular upper part 16 of the rubber element 9 passes therethrough. To be inserted (as shown in FIGS. 2 and 3).

  Please refer to FIGS. 2 to 6 depicting the assembly procedure for a conventional non-framed windshield wiper disclosed in US Pat. No. 7,210,189.

  First, the attachment channel 11 of the central support 10 is passed to the central part of the metal spine 7, and then the central support 10 is fixed to the central part of the metal spine 7 with bolts or rivets (as shown in FIG. 6).

  Next, each end of the metal spine 7 is inserted into a corresponding mounting channel 8 in the upper support of the blade body 6 (as shown in FIG. 4) so that each half of the metal spine 7 is covered by the blade body 6. (As shown in FIG. 6), and

  Finally, each rectangular upper portion 16 of the rubber element 9 is inserted into the corresponding lower mounting channel 12 and passage channel 14 and longitudinal rectangular openings 13 and 15 on the blade body 6 and the central support 10 (as shown in FIG. 5). Thereby, the entire windshield wiper is successfully assembled (as shown in FIG. 3).

  Despite the benefits described above, the conventional non-framed windshield wiper disclosed in US Pat. No. 7,210,189 has the following drawbacks.

  1. 7 to 7e, when the rubber element 9 is pushed onto the windshield 3 by the wiper arm 2, the vertical component force Fv is applied to the blade body 6, and the wiping edge of the rubber element 9 is on the upper surface of the windshield 3. Since the wiper arm 2 swings back and forth in the rain when pressed strongly against the metal (as shown in FIG. 7), when the wiper arm 2 swings forward, the metal spine 7 is bladed (as shown in FIG. 7a). On the other hand, when the wiper arm 2 swings back, the metal spine 7 has a backward horizontal component force applied to the blade body 6 (as indicated by the phantom line in FIG. 7c). Fh ′. As a result, the action of the front horizontal component force Fh and the rear horizontal component force Fh ′ will be indirectly applied to the rubber element 9 in the following order. First, through the flexible upper support 4 and the semi-rigid lower support 5, and then through the blade body 6, whereby the wiping edge of the rubber element 9 wipes over the top surface of the windshield 3, and the wiping effect To achieve.

  When the forward horizontal component force Fh is applied to the blade body 6 by the metal spine 7, the right side of the upper mounting channel 8 in the flexible flexible upper support 4 of the blade body 6 contacts and pushes the upper mounting channel. Acts horizontally by the right side of the spine 7, while the left side of the upper attachment channel 8 is separated and not acted horizontally by the left side of the metal spine 7 (as shown in FIG. 7a). Since the action of the front horizontal component force Fh and the rear horizontal component force Fh ′ is indirectly applied to the rubber element 9 continuously via the upper support 4 and the lower support 5 of the blade body 6, the rubber element 9 When the wiper arm 2 wipes on the top surface of the windshield 3 and thereby the wiper arm 2 swings forward, the right side of the upper mounting channel 8 in the flexible flexible upper support 4 becomes the metal spine 7. The left side of the upper mounting channel 8 in the flexible flexible upper support 4 is a gap d between the left side of the upper mounting channel 8 and the left side of the metal spine 7. To leave it deformed (as shown in FIG. 7b). When the wiper arm 2 swings backward, the backward horizontal component force Fh ′ changes its state, so that the right side of the upper mounting channel 8 in the flexible flexible upper support 4 of the blade body 6 is It is assumed that the left side of the upper mounting channel 8 will be acted horizontally by the left side of the metal spine 7 by contact and pressing, while being separated and will not be acted horizontally by the right side of the metal spine 7 (FIGS. Similarly, when the wiper arm 2 swings back, the left side of the upper mounting channel 8 in the flexible flexible upper support 4 can be expanded and contracted by the compression by the left side of the metal spine 7 when the wiper arm 2 swings back. On the other hand, the right side of the upper mounting channel 8 in the flexible flexible upper support 4 leaves a gap d ′ between the right side of the upper mounting channel 8 and the right side of the metal spine 7. To form (as shown in Figure 7e).

  In other words, the deformation gaps d and d ′ between each of the both sides of the upper mounting channel 8 and each of the corresponding both sides of the metal spine 7 are the forward horizontal component force Fh from the wiper arm 2 swinging back and forth. And alternately generated by the rearward horizontal component force Fh ′. As a result, the pressure transmission delay due to both deformation gaps d and d ′ causes temporary wiping stop and jerking of the rubber element 9 on the upper surface of the windshield 3, thereby generating unpleasant scraping noise, Impairs silence in the vehicle. Further, the normal windshield wiper swings on the vehicle windshield 3 is 40 to 50 times per minute, that is, 2400 to 3000 times per hour, and the above-mentioned temporary movement of the rubber element 9 on the upper surface of the windshield 3 is performed. Wiping stops and jerking will therefore occur the same number of times. Therefore, the service life of the rubber element 9 of the windshield wiper is shortened by frequent temporary wiping stops and jerking, with the result that the number of replacements and the cost increase.

  Examining and reconsidering the aforementioned drawbacks in the conventional windshield wiper disclosed in US Pat. No. 7,210,189, the main factor is that instead of the pressure of the metal spine 7 from the wiper arm 2 being directly applied to the semi-rigid lower support 5 It is added indirectly to the semi-rigid lower support 5 via the soft flexible upper support 4. Therefore, a delay in pressure transmission due to both deformation gaps d and d ′ in the flexible flexible upper support 4 is unavoidable due to the deformation of the flexible flexible material and thereby on the upper surface of the windshield 3. Temporary wiping stops or delays with jerking of the rubber element 9 occur. Such poor structural design not only impairs the transmission rules in dynamics, but also has a negative impact on the consumer as described above.

  Referring now to FIGS. 4-6 depicting the assembly procedure of a conventional windshield wiper of US Pat. No. 7,210,189, the outer dimension size of the metal spine 7 is the corresponding upper mounting channel 8 in the upper support 4 of the blade body 6. Since it is only slightly smaller than the inner dimension size, both coupling ends of the metal spine 7 and the upper mounting channel 8 are kept in line with each other during the assembly procedure and maintained in a horizontal state (as shown in FIG. 4). The insertion of the metal spine 7 into the must be made successfully. However, windshield wipers are low-priced products that are mass-produced over tens of millions of pieces per year to cover the full demand for new and used vehicles. The procedure of assembling the blade body 6 and the metal spine 7 requires close attention to alignment, so the assembler must pay more attention and waste more time to maintain an acceptable yield. I must. Therefore, not only does the assembly operator become tired easily, but also the assembly efficiency is lowered, the manufacturing cost is increased, and the market competitiveness is decreased.

  The main purpose of the present invention is a flat consisting of a rigid and elastic metal keelson strip, a saddle bracket for wiper adapter, an elongated scraping blade with upper wings, two rigid rigid clipping sleeve mounts, and a pair of end positioning caps A blade wiper, wherein each clipping sleeve mount and wiper adapter saddle bracket each have a first common receiving channel and a second receiving channel so that the resilient metal keelson strip is the first receiving channel. While the upper wing of the elongated scraping blade can provide a flat blade wiper that can penetrate the second receiving channel of both the wiper adapter saddle bracket and the clipping sleeve mount.When the wiper swings back and forth, the working force can be transmitted directly to the clipping sleeve mount by the metal keelson strip without any stopping, delay or jerking phenomenon, thereby causing noise There is no loss of silence inside the vehicle. Therefore, not only can the force load of the wiper arm be saved, but also the replacement cost can be reduced, resulting in an extended life of the wiper.

  Another object of the present invention is a flat blade wiper with a reduced width of each adapted guide that serves as an alignment precursor for the docking procedure between the main components of the wiper, each via its corresponding end. To provide a flat blade wiper including a clipping sleeve mount and an elastic metal keelson strip. The docking procedure can be performed quickly and easily even if these components are not in an exact alignment with each other. Because of the features described above, the alignment procedure of the main components of the wiper does not require any special attention, so that the reduction of the assembly operator's attention can be significantly reduced. Therefore, not only can assembly time be saved, but also the assembly efficiency is increased. As a result, manufacturing costs are reduced and market competitiveness is increased.

  Still referring to FIGS. 17-17b and 18-1b. Steps b and d describe the docking procedure through the corresponding ends of the clipping sleeve mount 40 and the elastic metal keelson strip 20, respectively. Due to the feature that the width of the curved shoulder 22 of each conforming guide part is slightly smaller than the width of the long longitudinal edge 23, the guide part serves as an alignment precursor in the docking procedure.

  First, for example, the lower second receiving channel 452 even if the fitting guide portion having the curved shoulder 2 of the elastic metal keelson strip 20 is not exactly aligned with the upper first receiving channel 451 of the clipping sleeve mount 40. Provides an extra tolerance for accommodating a guide portion having a curved shoulder 22 so that a matching guide portion having a curved shoulder 2 of an elastic metal keelson strip 20 can be inserted into the clipping sleeve mount 40. Next, confinement of the elastic metal keelson strip 20 within the clipping sleeve mount 40 with the extra tolerance provided by the lower second receiving channel 452 causes the upper first receiving channel 451 of the clipping sleeve mount 40 and Initially, the elastic metal keelson strip 20 that is not exactly in line can be adjusted (as shown in FIGS. 17a and 18a), and finally the clipping sleeve mount 40 and the elastic metal keelson strip 20 The alignment and docking between and can be further fine tuned to the desired state, completing the docking procedure (as shown in FIGS. 17b and 18b).

  Due to the features described above, the alignment procedure for the main components of the wiper does not require extra care and can significantly reduce the caution of the assembler. Therefore, not only can assembly time be saved, but also the assembly efficiency is increased. As a result, manufacturing costs are reduced and market competitiveness is increased.

  Further, referring to FIGS. 19-21, the main dynamic feature provided in the windshield wiper of the present invention is that the plastic clipping sleeve mount 40 is uniformly rigid and rigid throughout the structure. In actual operation, as mentioned in “Background Art” of this specification, the wiper arm 2 swings back and forth in the rain. Therefore, when it swings forward, the wiper on the wiper arm 2 moves forward and horizontally. Although the force Fh is applied, the backward horizontal component force Fh ′ is applied to the wiper on the wiper arm 2 when swinging back. The rigid and rigid (clipping sleeve mount 40) feature of the present invention provides effective resistance to deformations that often occur in the flexible and flexible upper support 4 on the blade body 6 described in US Pat. No. 7,210,189. . Thus, in operation, the inventive windshield wiper eliminates temporary wiping, jerking, or annoying scraping noise. As a result, stress deformation does not occur and the service life of the wiper can be extended.

  22 and 22a and 23 and 23a depict a vehicle flat blade wiper according to a second preferred embodiment of the present invention. Most of the components in the second embodiment are the same as the corresponding components in the first embodiment described above, but some of the components are changed as follows. The wiper adapter saddle bracket 300 is changed with respect to the wiper adapter saddle bracket 30 described above, the clipping sleeve mount 40 is changed from the clipping sleeve mount 40, and the end positioning cap 600 is changed from the end positioning cap 60. In this embodiment, the clipping sleeve mount 400 has a longitudinal ridge 402 and includes an upper tapered cross-sectional profile on the top surface 401 (as shown in FIG. 22a). The wiper adapter saddle bracket 300 has a hollow ridge 302 having an upper tapered cross-sectional profile provided on each of the two short lateral sides 301 and is coupled to the longitudinal ridge 402 of the clipping sleeve mount 400. The end positioning cap 600 has a hollow ridge 602 having an upper tapered cross-sectional profile on the upper surface 601. The cross-sectional profiles of hollow ridge 302 and hollow ridge 602 are the same as the cross-sectional profile of longitudinal ridge 402, but the internal dimensions are slightly larger than the external dimensions of longitudinal ridge 402 on clipping sleeve mount 400 (FIG. 23a). As shown). The longitudinal ridge 402 on the clipping sleeve mount 400 provides an equivalent air spoiler according to hydrodynamic principles when the elongated scraping blade 50 wipes over the windscreen.

  With further reference to FIGS. 24 and 25, the clipping sleeve mount 410 of the second preferred embodiment of the present invention is modified from the clipping sleeve mount 40 by providing a laterally asymmetric longitudinal ridge 412 on the top surface 411. As the elongated scraping blade 50 wipes over the windscreen, it also acts as an equivalent air spoiler according to the hydrodynamics.
