Claims

[Claim for Utility Model Registration] A visor electric drive device for a pair of foldable door mirrors glued to each left and right door of an automobile, each door mirror having a visor 2 supporting a mirror 3 and a stay provided on the outer surface of the vehicle body. A drive motor 17 rotatably mounted on the visor 1 and fixed on the visor 2
The visor 2 is rotated by the
and a storage side switch 29 that is turned on when the visor 2 is between the upright position and the storage completion position in accordance with the rotation of the visor 2 with respect to the stay 1.
A rotation detection switch 20 is provided between the stay 1 and the visor 2, and has a stand-up side switch 30 that is turned on when the visor 2 is just before the fully retracted position to the stand-up position. An operating switch 32 is provided having an operating switch 32a.
has a retraction visor switch 34 and an upright visor switch 33 which are self-maintained by a switching operation and are mutually linked to switch to the normally closed side or normally open side, and each of the drive motors 17, each contact 26 of one of the storage side switch 29 and the upright side switch 30 provided in each corresponding rotation detection switch 20, and the normally closed side contact 34b of the storage visor switch 34 provided in the operation switch 32. The contact points 27 of the storage side switch 29 of each rotation detection switch 20 and the other contact point 27 of the upright side switch 30 are respectively connected to the normally open side contact 33a of the stand-up visor switch 33.
, 28 are the normally open side of the storage visor switch 34 of the operation switch 32 and the standing visor switch 3
The contacts 34a and 33b on the normally closed side of No. 3 are connected correspondingly to each other, and the current is connected to each storage side switch 29.
The backflow prevention elements D ₁ , D ₂ are controlled so that the flow is controlled to flow in each of the directions of the other contact 27 and the normally closed contact 33b of the standing visor switch 33. are connected in series at predetermined positions between the respective contacts, and further, a battery 35 is connected between the common contacts 34c and 33c of the operating switch 32.
