DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A preferred embodiment of a wiper for an automobile rearview mirror in the present invention, as shown in FIGS. 1, 2 and 3, includes a rearview mirror, a transmitting device 2, a connect rod 3 and a wiper 4 as main components combined together.
The rearview mirror 1 consists of a base 10 and a mirror body 11 fixed on the base 10 and a circumferential stop edge 12 formed around the circumference of the base 10.
The transmitting device 2 is installed on a rear side of the base 10, composed of a rotary shaft 20 positioned on the surface of the mirror body 11.
The elongate connect rod 3 is fixed on the rotary shaft 20, moving together with the rotary shaft 20 when the rotary shaft 20 is swung by a motor.
The elongate wiper 4 is made of soft material, wrapped around the connect rod 3, and longer than the connect rod 3, and an elastic member 40 is placed inside the wiper 4, making the wiper flexible to bend freely. The wiper 4 has a wiping surface 41 closely contacting the surface of the mirror body 11.
Next, as shown in FIGS. 3, 4 and 5, the wiper 4 is to be used for cleaning raindrops on the mirror body 11, the transmitting device is started to swing the rotary shaft 20, which then forces the connect rod 3 to swing together, so the wiper 4 is also swung together with the connect rod 3. Meanwhile during swinging of the wiper 4, the wiper 4 located in a bent condition at an upper stop edge 12 of the base 10 is swung down, the wiper 4 may straighten up because of the elastic member 41, as shown in FIG. 4. When the wiper 4 moves to reach the lower stop edge 12 of the base 10, the wiper 4 is to be stopped by and bend along the lower stop edge 12 shaped convex owing to the elasticity of the elastic member 41, as shown in FIG. 5. At that moment, the rotary shaft 20 can be forced to swing reversely by the transmitting device 2, with the wiper 4 is also swung in the opposite direction (or reversely), i. e. swinging up toward the upper stop edge of the base 10, with the wiping surface 41 moving on the surface of the mirror body 11, cleaning off raindrops thereon. If the wiper 4 reaches the upper stop edge 12 of the base 10, the wiper 4 is to be stopped by the upper stop edge 12 and forced to swing down by means of the rotary shaft 20 driven by the transmitting device 2. In this way, raindrops may be cleaned off the mirror body 11, if there is any.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
