Abstract

A foldable exterior rearview mirror includes a housing, a bracket fixed to a side of a motor vehicle, and a connecting arm mounted in the housing and including a sleeve portion suitable for receiving an electric adjusting device or manual adjusting device. The manual adjusting device includes a pivot shaft and a support frame. The pivot axle includes an axle and a base fixed to a lower end of the axle. The base is mounted to the bracket. The support frame includes a cylindrical portion and a coupling portion extending outward from a periphery of the cylindrical portion. The cylindrical portion and the coupling portion of the support frame are removable engaged in the sleeve portion of the connecting arm. A user may select the manual adjusting device or the electric adjusting device to be mounted in the sleeve portion of the connecting arm.

Claims

1. A foldable exterior rearview mirror for a motor vehicle, comprising, in combination:

a housing;

a connecting arm mounted in the housing and including a sleeve portion, with a mirror being adapted to be mounted to the connecting arm;

a bracket adapted to be fixed to a side of a motor vehicle; and

an adjusting device including a pivot shaft and a support frame, with the pivot axle including an axle having a lower end and a base fixed to the lower end of the axle, with the base being mounted to the bracket, with the support frame including a cylindrical portion and a coupling portion extending outward from a periphery of the cylindrical portion, with the cylindrical portion and the coupling portion of the support frame being removably engaged in the sleeve portion of the connecting arm, with the cylindrical portion of the support frame being rotatably mounted around the axle and including an annular compartment in a bottom face thereof, with the base of the pivot shaft being rotatably received in the annular compartment of the cylindrical portion of the support frame.

2. The foldable exterior rearview mirror as claimed in claim 1, with the base including a top face having a plurality of annularly spaced first positioning holes and a plurality of annularly spaced second positioning holes, with an end wall defining the annular compartment of the support frame including a plurality of positioning grooves, with the adjusting device further including, in combination:

a positioning mechanism for positioning the support frame relative to the pivot shaft, with the positioning mechanism including a plurality of balls mounted between the top face of the base and the end wall defining the annular compartment;

a spring mounted around an upper portion of the axle that extends beyond the cylindrical portion of the support frame; and

a positioning ring mounted on top of the axle, with the spring being attached between the positioning ring and a top face of the cylindrical portion of the support frame to bias the cylindrical portion of the support frame toward the base, with each of the plurality of balls having an upper portion received in one of the plurality of positioning grooves of the support frame, with each of the plurality of balls having a lower portion selectively received in one of the plurality of first positioning holes or one of the plurality of second positioning holes.

3. The foldable exterior rearview mirror as claimed in claim 1, with the sleeve portion of the connecting arm including an annular section and a frame section, with the annular section including a cylindrical hole for receiving the cylindrical portion of the support frame, with the frame section including a coupling hole for receiving the coupling portion of the support frame.

4. The foldable exterior rearview mirror as claimed in claim 3, with the frame section of the sleeve portion of the connecting arm including two engaging grooves respectively in two opposite lateral walls thereof, and with the coupling portion of the support frame including two projections respectively on two opposite walls thereof and slidably received in the engaging grooves of the frame section of the sleeve portion of the connecting arm.

5. The foldable exterior rearview mirror as claimed in claim 4, with the frame section of the sleeve portion of the connecting arm including a plurality of first holes, with the coupling portion of the support frame including a plurality of second holes, further including, in combination:

a plurality of screws extending through the first holes into the second holes for securely fixing the coupling portion of the support frame in the frame section of the sleeve portion of the connecting arm.

7. The foldable exterior rearview mirror as claimed in claim 1, with the base including a top face having a plurality of annularly spaced first positioning holes and a plurality of annularly spaced second positioning holes, with an end wall defining the annular compartment of the support frame including a plurality of positioning grooves, with the adjusting device further including, in combination:

a positioning mechanism for positioning the support frame relative to the pivot shaft, with the positioning mechanism including a plurality of balls mounted between the top face of the base and the end wall defining the annular compartment;

a spring mounted around an upper portion of the axle that extends beyond the cylindrical portion of the support frame; and

a positioning ring mounted on top of the axle, with the spring being attached between the positioning ring and a top face of the cylindrical portion of the support frame to bias the cylindrical portion of the support frame toward the base, with each of the plurality of balls having an upper portion received in one of the plurality of positioning grooves of the support frame, with each of the plurality of balls having a lower portion selectively received in one of the plurality of first positioning holes or one of the plurality of second positioning holes.

6. The foldable exterior rearview mirror for a motor vehicle, comprising, in combination:
