Abstract
The utility model discloses a drive connecting rod of a windscreen wiper device, which consists of a metal rod part, and injection molding parts respectively assembled on the two ends of the metal rod part, wherein one of the injection molding parts on the two ends of the metal rod part is a single-ball injection molding part, and the other one is a double-ball injection molding part; the single-ball injection molding part consists of a ring body and a round cover which is formed on the top of the ring body into a whole; and the middle of the inner surface of the round cover of the single-ball injection molding part is provided with a raised limit boss. The utility model adopts the structure, one end of the metal rod part is assembled with a single ball, and the other end thereof is assembled with double balls, since the middle of the inner surface of the round cover of the single-ball injection molding part is provided with the raised limit boss, the limit of the freedom of the movement of the single ball is increased, so the drive connecting rod can keep uniform stress when the windscreen wiper works, and the jitter is avoided when the windscreen wiper works.
Description
Technical field
The utility model relates to a kind of kinematic link of wiper device.
Background technology
The kinematic link of wiper device is by metal rod, the moulding that is assemblied in the metal rod two ends is respectively formed, moulding has single bulb moulding and two two kinds of specifications of bulb moulding, injecting head on the kinematic link and two bulb moulding assemblings, two bulbs can be in two bulb mouldings activity freely, be not subjected to any restriction, single bulb moulding is made up of the dome that ring body and ring body end form one, injecting head on the kinematic link and the assembling of single bulb moulding, single bulb can activity be subjected to the part constraint in single bulb moulding, jitter phenomenon easily takes place in discontinuity in the kinematic link operational process of this spline structure during wiper work.
The utility model content
Technical problem to be solved in the utility model is: a kind of kinematic link of wiper device is provided, and it is stressed even that the kinematic link of this kind wiper device can keep when wiper is worked, and occurs jitter phenomenon when avoiding wiper work.
Solve this technical problem, the technical solution of the utility model is: a kind of kinematic link of wiper device, the moulding that is assemblied in the metal rod two ends is formed by metal rod, respectively, one of them is single bulb moulding for the moulding at metal rod two ends, another is two bulb mouldings, described single bulb moulding is made up of the dome that ring body and ring body end form one, and the dome inside face middle part of described single bulb moulding is provided with bossed positive stop lug boss.
The positive stop lug boss height at the dome inside face middle part of described single bulb moulding is 1～1.5 millimeter.
The kinematic link of a kind of wiper device of the utility model adopts such structure, metal rod one end assembles single bulb, the two bulbs of other end assembling, the dome inside face middle part of single bulb moulding of kinematic link is provided with the positive stop lug boss of protuberance, increased restriction to single bulb freedom of motion, make kinematic link when wiper is worked, can keep stressed even, occur jitter phenomenon when avoiding wiper work.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of kinematic link of wiper device, the moulding that is assemblied in metal rod 1 two ends is formed by metal rod 1, respectively, one of them is single bulb moulding 2 for the moulding at metal rod 1 two ends, another is two bulb mouldings 3, single bulb moulding 2 is made up of the dome 5 that one is formed on ring body 4 and ring body 4 tops, and the dome 5 inside faces middle part of single bulb moulding 2 has the positive stop lug boss 6 of protuberance, and positive stop lug boss 6 highly adopts 1～1.5 millimeter.
The kinematic link of a kind of wiper device of the utility model adopts such structure, metal rod 1 one ends assemble single bulb, the two bulbs of other end assembling, the dome 5 inside faces middle part of single bulb moulding 2 of kinematic link is provided with the positive stop lug boss 6 of protuberance, increased freedom of motion restriction to single bulb, make kinematic link when wiper is worked, can keep stressed even, occur jitter phenomenon when avoiding wiper work.
