Movement mechanism and wing mirror for a vehicle provided with such a movement mechanism

Abstract

A movement mechanism comprising a substantially spherical holder and a substantially bowl-shaped ring, which are rotatable relative to each other about a first axis and a second axis enclosing an angle of approximately 90 DEG to the first axis. Driving means are provided for enabling movement of the holder relative to the ring and comprise a first non-straight driving rod bearing-mounted in the holder, as well as means for activating the driving rod and a second non-straight driving rod bearing-mounted in the holder, as well as means for activating the driving rod. The first driving rod and the second driving rod are rotatable about a third and a fourth axis, respectively, which third and fourth axes are mutually parallel and lie in a plane equal or parallel to the top face of the holder and which third and fourth axes are parallel to or coincide with the first axis.

Description

technical field [0001] The present invention relates to a kinematic mechanism comprising a substantially spherical cage and a substantially bowl-shaped annular member, the cage and the annular member being capable of orbiting a first axis of rotation relative to each other, the first axis lying in a plane substantially parallel to the top surface of the cage, the second axis lying in a plane corresponding to or parallel to the top surface of the ring In a plane, the second axis is at an angle of about 90° to the first axis, and a transmission is provided for enabling the movement of the cage relative to the ring, the transmission comprising a support mounted on the a non-linear first transmission rod in a cage and means for actuating the transmission rod, and a non-linear second transmission rod and means for actuating the transmission rod supportedly mounted in said cage The device, wherein the transmission rods have the shape of ring segments, the first transmission rod and...

AI Technical Summary

Problems solved by technology

Although the kinematic mechanism functions satisfactorily, in some cases where an increased adjustment torque is required to affect the movement of the cage relative to the annulus, the kinematic mechanism is less accurate, which results in additional actuation of the transmission rod for accurate mutual positioning

Furthermore, when the motor is driven by a 24V battery, the accuracy of this known kinematic mechanism does not meet the highest requirements in some cases
