TECHNICAL FIELD
[0001] The utility model belongs to the technical field of wiper, and relates to a connecting structure of a wiper end cover and a rubber strip mounting seat. BACKGROUND
[0002] In the daily operation of automobiles and various vehicles, the wiper is a key component for ensuring clear driving vision, and its performance directly relates to driving safety. In the wiper system, the connecting structure of the connecting end cover and the rubber strip mounting seat is an extremely important component. The structure not only needs to ensure that the wiper arm power can be stably transmitted to the rubber strip to achieve efficient water wiping, but also needs to adapt to various complex use environments and working conditions.
[0003] The connecting mode of the traditional wiper connecting end cover and the rubber strip mounting seat has many disadvantages. In terms of connection stability, most of them adopt simple buckles or bolt connections. After long-term use, affected by factors such as vehicle driving vibration, temperature change, and rain erosion, the buckles are prone to loosen, and the bolts are prone to slipping, which causes gaps between the connecting end cover and the rubber strip mounting seat. When the wiper works, it will shake, the water wiping effect will be greatly reduced, and in extreme cases, the rubber strip cannot normally adhere to the glass surface, which seriously threatens the driving vision.

[0009] As a further scheme of the utility model: the opening position of the limiting sleeve opening adopts a horn-shaped structure which is wide outside and narrow inside.
[0010] As a further scheme of the utility model: a plurality of hollow grooves are formed on the connecting part.
[0011] The utility model discloses the beneficial effect: through the connecting seat structure realizes the full range installation limit work between connecting end cover and rubber strip mounting seat up and down, left and right and before and after. Prevent the rain from scratching the high -speed operation or when receiving external force and move before and after, guarantee the water track stability of scratching, prevent the clearance produced by loosening, ensure that the rain is scratched stably, promote the driving safety, reduce the rubber strip wear and tear simultaneously, prolong the service life.
