Description

  The present invention relates to a structure of an array combination type wiper. In particular, it is composed of a receiving block and a weight block as a vehicle wiper that can stably and completely come into contact with various types of vehicle windshields of different curvatures, with different lengths depending on the selection of the combination position and the required quantity. It can be combined with standard flexible curved bullet pieces to produce wiper products with different length standards, greatly reducing production costs, and integrated with windshields with various curvatures, The present invention relates to a structure of an array combination type wiper capable of effectively achieving a function.

As automobile production / shipments have increased, the amount of use of automobile wipers has also increased significantly. Further, as one of the daily tasks to be observed by the driver, it is desirable to periodically replace the wiper on the windshield in order to ensure driving safety. Therefore, the amount of use of automobile wipers continues to increase.
On the other hand, since the area of the windshield differs depending on the vehicle type, the length standard of the wiper to which it corresponds also differs. That is, for a wiper manufacturer, how to manufacture an enormous quantity of automobile wiper products in conformity with various standard forms by the production method with the highest efficiency and the lowest cost is an extremely important issue.
For this, the only measure is to constantly change the design of the wiper structure, such as US Pat. Nos. 6588048, 7150066, 7254862, US2006 / 0090282 and There are related technologies such as 2006/0179597.
As is well known, the windshield areas of home passenger cars and RV cars or other large and small trucks are all different. Therefore, if the length of the wiper used in combination with the wiper is not different, the wiper effect for wiping the effective area on the automobile windshield cannot be achieved. That is, if the windshield area is relatively large, a longer wiper must be combined, and if the windshield area is relatively small, a shorter wiper must be combined.
However, there are very many types of wiper length standards that are actually on the market. However, when taking a single length standard, the known wiper satisfies the effective area wiper function and effect of different curvature windshields. Although it is possible, it cannot be applied integrally when trying to cope with different windshield areas. However, if the wiper length standard is changed, the related components must be resized and remanufactured. Therefore, in the design posted by each of the above known wipers, if it is possible to support all different length standard wiper products in the market, the total number of other related dedicated parts derived from various length standard wipers And the cost of component classification and management will increase accordingly. For this reason, there exists a fault that it does not have market competitiveness in the manufacturing cost of a wiper.

As a result, the cost of the entire production can be reduced, the market competitiveness can be greatly improved, and the environment-friendly and economical saving function and effect are combined.
Furthermore, the structure of the arrangement combination type wiper is adjusted by mutual arrangement combination adjustment of the several receiving blocks and the weight block, and is further fitted on the flexible curved bullet piece. The weight distribution applied on the glass can be averaged and made uniform, and the stick-shaped wiper piece and the automobile windshield can be in close and stable contact with each other, and the function and effect of the wiper for wiping water can be enhanced.

  As described above, the present invention can quickly produce wiper products of various length standards by changing the number of arrangement combinations of the receiving block and the weight block, while requiring few components. As a result, variations in length standards continually require additional spending, eliminating the need to make molds and manufacture new standard parts. As a result, the cost of inventory management or production can be greatly reduced, and elastic and flexible diversification can be truly achieved. In this way, the best mass production environment of different length standard wiper products can be created, the cost of the overall production can be reduced, and the competitiveness of the market can be greatly improved.
