Description

Effluent stealthy arm scraping assembly

Technical Field

The utility model relates to a wiper arm assembly applied to an automobile windscreen wiper.

Background

At present, a wiper (also called a wiper) is an indispensable part of an automobile, and the wiper is used for receiving power transmitted by a wiper motor and a connecting rod mechanism and generating wiper arm pressure at the same time, and wiping the windshield by a wiper blade so as to clean foreign matters on the windshield. A typical wiper blade is comprised of a plurality of subassemblies including a wiper motor, a linkage (including an output shaft) and wiper arm assembly, a wiper blade, a motor mounting plate assembly, and the like, and is also equipped with a wiper water spray device. The wiper arm assembly comprises a wiper arm head (also called a wiper joint) and an extension arm, the connecting structure is simple, the firmness is not enough, and the wiper arm head is basically made of aluminum alloy and zinc alloy through die casting. The wiper water spraying device matched with the wiper arm assembly basically connects the washer outlet pipe and the wiper outlet pipe together in a conversion mode through the two corner through pipes, then holes are formed in the front wall panel of the vehicle body, then the two corner through pipes are fixed at the holes of the front wall panel of the vehicle body, the two corner through pipes and the wiper outlet pipe are exposed out of the front wall panel of the vehicle body, the appearance is not attractive, and the risks of water inflow of a vehicle are increased due to the holes of the front wall panel of the vehicle body. As a rubber part, the wiper outlet pipe and the corner two-way pipe are exposed outside the vehicle for a long time, and are easy to age and damage due to sunshine and rain, so that the durability and the service life of the wiper outlet pipe and the corner two-way pipe are affected.

Disclosure of Invention

The utility model aims to overcome the technical defects and provide the water outlet stealth type wiper arm assembly which is firm in connection and can hide the water outlet of the wiper.

The aim of the utility model can be achieved by the following technical scheme: the water outlet stealth type wiper arm assembly comprises a wiper arm head and an extension arm, wherein a composite bushing and a pin are arranged at the joint of the wiper arm head and the extension arm through a connecting hole, a drag hook rivet is arranged at one end of the wiper arm head and near the connecting hole through a drag hook rivet hole, a taper hole is formed in the other end of the wiper arm head, a fixed clamping hook is arranged at the bottom of the wiper arm head, a wiper outlet pipe is arranged on the fixed clamping hook, a tension spring is arranged at the bottom of the extension arm, the tension spring is connected with the drag hook rivet through a drag hook, and the wiper outlet pipe passes through the drag hook rivet and the pin and penetrates through the tension spring.

After the utility model is adopted, the bottom of the wiper arm head is utilized to be provided with the wiper water outlet pipe through the fixing clamp hook, and the wiper water outlet pipe passes through the draw hook rivet and the pin and then passes through the tension spring at the bottom of the extension arm, so that the effect that the wiper water outlet pipe is hidden in the wiper arm head and the bottom of the extension arm is achieved, the wiper water outlet pipe is not exposed outside a vehicle, the appearance of the vehicle body is not influenced, and the risk of water leakage of the vehicle is avoided. And the wiper arm head and the extension arm are connected through pins, drag hook rivets and drag hooks in multiple modes, so that the connection firmness is high, and the service life and the durability of the wiper arm head and the extension arm are prolonged.
