The invention relates to an "adjusting non-bracket type wiper structure", belonging to the technical field of automobile wipers, wherein the outer cover sheath in the structure can be matched with the metal shrapnel body of different length specifications after cutting, and the socket is achieved. The jacket is combined to form non-bracket wipers of different lengths and has the effect of adjusting the production of wipers of different lengths.

In recent years, the windshield wipers used in the newly manufactured factory cars are mainly based on the Flat Blade Wiper, which makes the traditional bracket wipers gradually eliminated. The reason is that the traditional bracket wipers There are many components, the overall weight is heavy, and the power consumption is also large. In addition, the wiper is a consumable product. When the wiping effect affects the driving safety, the new product must be replaced. Therefore, the accumulated conventional scaffolding wiper is replaced every year. The quantity will relatively impose a large burden on the environment; on the other hand, the non-bracket wiper will not have the aforementioned disadvantages due to the absence of the bracket member.

Therefore, non-bracket wipers of various structures have been developed, such as: US Patent Publication No. US2006/0064841, US2008/0098559, Chinese Utility Model Patent CN201472319, CN201753049, CN201745547, Japan The disclosures of the inventions are disclosed in the first figure, which is mainly composed of a central outer cover sheath 1 and the like. The left and right side cover jackets 2 are formed; due to the different sizes of the front windshield of different models, the length of the wiper used together may be different. In other words, the two side covers in the conventional non-bracket wiper There are also several types of length specifications of the sheath 2, which can be combined with the central outer cover sheath 1 to form wipers of different lengths. Therefore, for the factory producing the wiper, when producing the same type of non-bracket wiper, Different mold developments must be made for the side cover sheaths 2 of different length specifications, which will result in a large increase in the overall mold cost and lead to production non-production. Increase in the overall cost of rack wipers, and then passed on to the consumer's purchase price, to the detriment of the competitive market, while excessive amount of mold development and its future scrap, can also cause a greater burden on the environment.
