Abstract
An apparatus includes a motor having one or more gears and a shaft operably coupled to the one or more gears. The shaft actuates to adjust a field of view (FoV) of a camera. The apparatus further includes a bracket having a passage in which the shaft is at least partially disposed, and a channel. A spring is at least partially disposed with the channel of the bracket and is configured to reduce a backlash within the one or more gears of the motor.
Claims20
A stand comprising:
- a first portion;
- and
- a second portion including:
- a bracket at least partially disposed within the second portion, the bracket having a channel,
- a neck at least partially disposed within the second portion, the neck having a first end coupled to the bracket and a second end coupled to a device,
- a first motor at least partially disposed with the second portion,
- a second motor at least partially disposed within the second portion, the second motor having:
- a housing, and
- a shaft coupled to the bracket, and
- a spring having a first end coupled to the housing of the second motor and a second end operably coupled to the bracket, the spring being at least partially disposed within the channel and configured to at least partially reduce a backlash of gears within the second motor.

A device comprising:
- a mount for coupling to an electronic device having a camera;
- a first motor configured to actuate in a first direction for adjusting a field of view (FoV) of the camera;
- a second motor configured to actuate in a second direction, different than the first direction, for adjusting the FoV of the camera;
- a bracket coupled to the second motor and the mount;
- and
- a spring at least partially disposed within the bracket and configured to reduce a backlash within one or more gears of the second motor.
