Abstract
The utility model relates to an automobile component, in particular relates to an automobile wiper, comprising a motor, a crank-rocker mechanism and a rain wiper. The output shaft of the motor is connected with the crank of the crank-rocker mechanism through a gear decelerating mechanism. The rocker of the crank-rocker mechanism is in linkage connection with the rain wiper. A connecting rod, the crank and the rocker of the crank-rocker mechanism are articulated together. A baffle, which is used for preventing the axial displacement between the crank and the connecting rod, the connecting rod and the rocker, is arranged outside the crank, the connecting rod and the rocker. The baffle and the gear decelerating mechanism box are fixedly connected. The baffle is used to avoid the displacement between the crank and the connecting rod, the connecting rod and the rocker, which makes the crank-rocker mechanism close to the theoretical plane four-bar mechanism. Even being used for a long time, the mechanism can not be loosened to fall off, which is different from the riveted mechanism, and so the rigid and efficiency of the crank-rocker mechanism are ensure, and the dry wiping requirement is achieved.
Description
Technical field
The utility model relates to vehicular spare parts, particularly a kind of automobile water wiper.
Background technology
Present automobile water wiper usually only strikes off it having under the situation of rainwater, and in the serious occasion of some dust, strike off and be bonded at car windscreen dust on glass, then must after spray water, just can strike off and not competent scraping, trace it to its cause, motor horsepower output in Windshield Wiper inadequately, be that mainly its hinged place of four-bar mechanism in the present Windshield Wiper adopts riveted way to connect, after for a long time, can cause consequently whole four-bar mechanism rigidity deficiency of longitudinal travel.If not competently scrape then windshield washer must be adorned in addition, increased cost on automobile.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned automobile water wiper, and a kind of automobile water wiper that can driedly scrape is provided.
The purpose of this utility model is achieved by the following technical solution: a kind of automobile water wiper, include motor, quadric linkage and windscreen wiper, described motor output shaft is by the crank connecting link of gear reduction and quadric linkage, the rocking bar and the windscreen wiper of described quadric linkage are connected, connecting rod in the described quadric linkage and crank and rocking bar are hinged, also be provided with in the outside of crank, connecting rod and rocking bar prevent between crank and the connecting rod, axially movable baffle plate between connecting rod and the rocking bar, baffle plate is captiveed joint with the gear reduction casing.
The utility model further is set to: the jointed shaft and the crank of described crank and connecting rod are wholely set, and the jointed shaft and the rocking bar of rocking bar and connecting rod are wholely set.
The utility model further is set to again: described jointed shaft respectively is connected with crank and rocking bar by bearing.
The beneficial effects of the utility model are: utilize baffle plate to block crank and connecting rod, connecting rod and rocking bar and make and axially do not produce slippage between them, make quadric linkage near theoretic four-bar linkage, even after using for a long time, yet can not have forming loosening even come off as riveted joint, guarantee the rigidity and the efficient of quadric linkage, thereby can realize dried requirement of scraping.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
By as can be known shown in Figure 1, a kind of automobile water wiper of the utility model, include motor 1, quadric linkage 2 and windscreen wiper 3, described motor 1 output shaft is connected with the crank 21 of quadric linkage 2 by gear reduction 4, the rocking bar 23 and the windscreen wiper 3 of described quadric linkage 2 are connected, connecting rod 22 in the described quadric linkage 2 is hinged with crank 21 and rocking bar 23, at crank 21, the outside of connecting rod 22 and rocking bar 23 also is provided with and prevents between crank 21 and the connecting rod 22, axially movable baffle plate 24 between connecting rod 22 and the rocking bar 23,25, baffle plate 24,25 captive joint with gear reduction 4 casings 41.Utilizing baffle plate 24,25 to block crank 21 and connecting rod 22, connecting rod 22 and rocking bar 23 makes and does not axially produce slippage between them, make quadric linkage 2 near theoretic four-bar linkage, even after using for a long time, yet can not have forming loosening even come off as riveted joint, guarantee the rigidity and the efficient of quadric linkage, thereby can realize dried requirement of scraping.
Described crank 21 is wholely set with crank 21 with the jointed shaft 211 of connecting rod 22, and rocking bar 23 is wholely set with rocking bar 23 with the jointed shaft 231 of connecting rod 22.Jointed shaft 211 is wholely set with rocking bar 23 with crank 21, jointed shaft 231, has guaranteed that jointed shaft can not move in hinge hole, thereby has guaranteed the rigidity of jointed shaft, has promptly further guaranteed the rigidity of quadric linkage.Certainly, jointed shaft and crank, jointed shaft and rocking bar are not wholely set within the utility model protection domain yet.
In above-mentioned, jointed shaft 211 is connected with crank 21 by bearing 26, and jointed shaft 231 is connected with rocking bar 23 by bearing 27, connects by bearing, can make crank 21 and connecting rod 22, be connected 22 and rocking bar 23 between rotate more flexibly along hinged seat, make the quadric linkage operation more smooth and easy.
(present power of motor is generally 30W to the utility model embodiment at expanded motor power, and the motor of the utility model embodiment is 50W), strengthen output torque (operation torque Mn=2.55N.m during 30W, present embodiment Mn=4.35N.m) outside, utilize above-mentioned technical scheme to make and no longer include longitudinal travel between connecting rod in the quadric linkage and crank and the rocking bar, thereby make quadric linkage near theoretic four-bar linkage, therefore have enough rigidity and efficient, thereby can satisfy the dried requirement of scraping of Windshield Wiper.
