An automotive wiper comprising: the vortex flow device comprises turbulence wings, a large bone, a middle bone, connecting arms, elastic pieces with radian, a spring plate and rubber strips, wherein the spring plate is clamped in the middle of the rubber strips; the vortex wing bottom is provided with the draw-in groove, the chimb that big bone and well bone both sides set up, the chimb of big bone and well bone both sides is installed in the draw-in groove of vortex wing bottom, pass through between big bone and the well bone the shell fragment that has the radian is connected. Through the shell fragment that has the radian forms a radian between well bone and the big bone, when the pressure of car rocking arm pressed to the windshield wiper, big bone and well bone transmitted pressure to every linking arm on, pressure distribution was even, guaranteed adhesive tape and car glass and laminated completely, avoided the windscreen wiper middle part can not laminate with car glass's phenomenon completely.

Description

car wiper

technical field

The utility model belongs to the field of auto parts, in particular to an automobile wiper.

Background technique

Wiper is an indispensable accessory in the field of automobile manufacturing. Traditional car wipers are divided into bone wiper and boneless wiper. The traditional bone wiper moves slowly and has an unattractive appearance; the traditional boneless shrapnel arc The radian of the car glass cannot be well matched, the pressure of the wiper on the car glass is uneven, and the middle part of the wiper cannot effectively wipe the rain.

Utility model content

The technical problem to be solved by the utility model is to provide a car wiper, which has a beautiful appearance, the pressure distribution of the wiper on the car glass is uniform, and the rainwater on the car glass can be completely cleaned.

In order to solve the above problems, the utility model adopts the following technical solutions: a car wiper, including: spoiler wing, large bone, middle bone, connecting arm, shrapnel, spring plate and rubber strip, the spring plate is clamped on the rubber strip In the middle part, the rubber strip is connected to the connecting arm, the outer connecting arm is connected to the middle bone, and the inner connecting arm is connected to the large bone; the bottom of the spoiler is provided with a slot, and the two sides of the large bone and the middle bone are provided The convex edge is installed in the slot at the bottom of the spoiler, and the big bone and the middle bone are connected by the curved elastic piece.

In a preferred solution, the curvature of the elastic piece with curvature is between 160°-170°.

In a preferred solution, opposite circular protrusions are arranged in the middle of the central bone, and the outer connecting arm is clamped between the circular protrusions of the central bone.

In a preferred solution, corresponding circular bosses are provided inside the big bones, and the inner connecting arm is clamped between the circular bosses of the big bones.

The automobile wiper provided by the utility model includes two support frames, the shrapnel is connected with the rubber strip, the rubber strip is clamped with the connecting arm, the outer connecting arm is connected with the middle bone, the inner connecting arm is connected with the big bone, and the middle bone and the middle bone are connected. At the same time, the large bone is clamped in the slot of the spoiler wing, and the large bone and the middle bone are connected through the curved elastic piece. Through the curved shrapnel, a radian is formed between the middle bone and the big bone. When the pressure of the rocker arm of the car is pressed against the wiper, the big bone and the middle bone transmit the pressure to each connecting arm, and the pressure is evenly distributed. Ensure that the rubber strip is fully bonded to the car glass, avoiding the phenomenon that the middle part of the wiper cannot be completely bonded to the car glass.
