Flat blade wiper

Abstract

The invention provides a flat blade wiper which includes an elastic metal keelson strip, a saddle bracket for receiving a wiper adapter, two rigid hard clipping sleeve mounts and a pair of end positioning caps. Each clipping sleeve mount and wiper adapter saddle bracket has a first compatible accommodating channel which is flat and wide and a second accommodating channel which is narrow and high respectively so that the elastic metal keelson strip can run through the first accommodating channel while the upper wing section of the elongated scraping blade can run through the second accommodating channel in both the wiper adapter saddle bracket and the clipping sleeve mount. When the wiper swings back and forth, an acting force is directly transmitted to the clipping sleeve mounts by the metal keelson strip without any pause or delay, eliminating jerking so that no noise is incurred to spoil the internal tranquility of the vehicle.

Description

【Technical field】 [0001] The invention relates to a structure of a non-support type wiper. During the force transmission process of the wiping action of the wiper, there will be no delay or short-time pause vibration phenomenon, and the assembly work can be greatly reduced. Concentration and reduce fatigue, thereby reducing the overall assembly cost and man-hours, and improving the production capacity of mass production, and have a competitive advantage in market prices. 【Background technique】 [0002] In recent years, the windshield wipers used in newly manufactured cars are mainly flat blade wipers, which makes the traditional flat blade wipers tend to be gradually eliminated. The reason is that the traditional flat blade wipers There are many components, the overall weight is heavy, and the power consumption is also large, and it is easy to generate jumping and flying noise after wiping the windshield for a period of time, which affects the tranquility of the car.

Problems solved by technology

[0007] As for the main reason for the above-mentioned defects, it is not that the force from the wiper rocker arm 2 is directly transmitted from the rigid metal spine 7 to the rigid bottom support 5, but is transmitted from the rigid metal spine 7. The active force is firstly used as the interface for power transmission through the soft upper support part 4, and then indirectly transmits the active force to the hard bottom support part 5, so that the force transmission of each back and forth wiping All can produce short-term hysteresis, and cause the result that the rubber scraper 9 vibrates on the automobile windshield 3, so this kind of bad structure, in addition to violating the design on the principle of mechanical transmission, also brings consumers The consequences of the above adverse effects

[0008] 2. Another example Figure 4 and Image 6 As shown, because the size of the outer edge of the rectangular section of the metal spine strip 7 is only slightly smaller than the size of the inner edge of the rectangular section of the assembly channel 8 in the upper support part 4, so in the combined operation, when the metal spine strip 7 is about to be inserted into the scraper When the assembly channel 8 of the upper support part 4 of the bar body 6, the rectangular sections of the two must be kept in a horizontal state, and then the rectangular sections of the two must be aligned with each other in a visual mode (such as Figure 4 As shown), the two wiper strips 6 can be put through the metal spine strip 7 respectively. However, the windshield wiper is a mass-produced low-priced product, with an annual output of more than tens of millions (including new cars and total demand in the used car market), if every time when combining the metal spine strip 7 and the scraping strip body 6, all have to be so cautious, then for the combination operator, not only need to pay a lot of concentration and increase fatigue Excessive (avoiding high defect rate of products), it will also reduce the efficiency of assembly operations, and lead to an increase in the overall assembly cost, which is not conducive to the lack of market price competitiveness.
