Description
Technical field
The utility model relates to automobile component structure, is specifically related to a kind of automobile water wiper transmission arm waterproof construction.This structure applications is in automobile water wiper assembly, by optimizing transmission arm Integral connection structure and waterproof construction to promote Windshield Wiper transmission arm water resistance.
Background technology
Automobile water wiper assembly is one of critical component on automobile, and driving is played to safety control effect.As the disclosed a kind of automobile water wiper assembly of CN 203637772 U, comprise a wiper motor and on crank, a fixed link, two scraping arm pivots, two pivot suspension seats, two wiper arms, two pivot swinging arms and two connecting rods, the two ends of described fixed link are connected with the supporting base being installed on vehicle body, described scraping arm pivot is set in supporting base and part protrudes upward the top in supporting base, institute's wiper arm is assemblied in the part that scraping arm pivot protrudes upward, it is characterized in that: the crank on described wiper motor is up fixed on the middle part of fixed link, described pivot swinging arm and connecting rod and wiper arm are positioned at the same side of scraping arm pivot, pivot swinging arm one end is between the top of supporting base and wiper arm and be fixed as one with scraping arm pivot, the other end is flexibly connected with one end of connecting rod, the other end of connecting rod is flexibly connected with the crank of wiper motor.This automobile water wiper assembly does not arrange transmission arm waterproof construction.CN202294639U discloses " a kind of wiper motor of waterproof ", comprises the electrical motor that output shaft is connected with connecting rod mechanism, the external swept area of wiper blade of output shaft of connecting rod mechanism; The outside of electrical motor and connecting rod mechanism is provided with waterproof case.Adopt after structure of the present utility model, can effectively prevent that rainwater from invading wiper motor, thereby extend motor service life.But, transmission arm waterproof construction is not set yet.
Common a kind of automobile water wiper transmission arm waterproof construction, as shown in Figure 1, former scraping arm pivot 4 coordinates with former pivot suspension seat 2 and passes former pivot suspension seat, former wiper arm 1 is connected with the upper end of former scraping arm pivot 4 and is positioned at the upper end of former pivot suspension seat, former pivot swinging arm 5 is connected with the lower end of former scraping arm pivot 4 and is positioned at the lower end of former pivot suspension seat, former connecting rod 6 is hinged with one end of former pivot swinging arm 5, be that former wiper arm 1 is positioned at the upper end near the former pivot suspension seat 2 of automobile external, former pivot swinging arm 5 is positioned at the lower end of former pivot suspension seat 2, former water conservancy diversion bowl 3 is connected on former scraping arm pivot 4, and between former wiper arm 1 and former pivot swinging arm 5, , utilize former water conservancy diversion bowl 3 and the interference fit of former scraping arm pivot 4 to be fixed.Adopt rainwater on the connecting rod of automobile water wiper assembly of this structure easily to enter connecting rod and the hinged joint part of pivot swinging arm, joint part water inlet will speed up joint part and gets rusty, wear and tear, causes the problem generations such as abnormal sound.
Summary of the invention
The purpose of this utility model is a kind of automobile water wiper transmission arm waterproof construction, it can prevent that the rainwater on the connecting rod of automobile water wiper assembly from entering the joint part that connecting rod is connected with pivot swinging arm, strengthen water resistance, reduce joint part and get rusty, wear and tear, avoid occurring abnormal sound.
A kind of automobile water wiper transmission arm waterproof construction described in the utility model, comprise pivot suspension seat, coordinate and pass the scraping arm pivot of pivot suspension seat with this pivot suspension seat, the upper end of this scraping arm pivot is connected with the scraping arm joint of a wiper arm, it is characterized in that: one end of a pivot swinging arm is fixedly connected with the upper vertical of described scraping arm pivot the other end of this pivot swinging arm and a rod hinge connection;
One waterproof jacket is enclosed within on described scraping arm pivot, and this waterproof jacket is positioned at the position that described scraping arm pivot is connected with pivot swinging arm, and encases described pivot swinging arm.
Described a kind of automobile water wiper transmission arm waterproof construction, described in it, the material of waterproof jacket is rubber.
The utility model compared with prior art has the following advantages: due to pivot swinging arm and connecting rod upward, its top has front windshield trim board to cover, so rainwater can not flow to connecting rod and above scraping arm pivot; The joint being connected with connecting rod due to pivot swinging arm upward, on pivot swinging arm, added rubber waterproof gum cover water conservancy diversion simultaneously, the rainwater flowing down from pivot suspension seat can not flow to the joint part that pivot swinging arm is connected with connecting rod yet, thereby avoid the impact of rainwater on windscreen wiper system transmission device, extended the service life of product.
