Abstract
A sliding mechanism used in a portable electronic device is described. The sliding mechanism includes a body section, a cover section, a rolling disk and a coil spring. The rolling disk is fixed to the cover section. A center of the coil spring is fixed to a center of the rolling disk. An end of the coil spring is fixed to a periphery of the rolling disk. When the rolling disk rotates relative to the body section, the coil spring generates a force towards or against the sliding direction of the cover section.
Claims16
A sliding mechanism, comprising:
- a body section defining a sliding slot, the sliding slot including a first slot section and a second slot section, the first slot section parallel and offset with respect to the second slot section;
- a cover section slidably mounted to the body section;
- a rolling disk fixed to the cover section, a guiding pole protruding from a center of the rolling disk, the guiding pole slidably received in the sliding slot;
- a first friction board;
- a second friction board, the first friction board and the second friction board parallel secured on opposite edges of the sliding slot;
- and
- a coil spring, a center of the coil spring fixed to a center of the rolling disk, an end of the coil spring fixed to a periphery of the rolling disk;
- wherein the rolling disk rotates along the first friction board and the coil spring generates a resisting force against the sliding direction when the guiding pole slides along the first slot section to the second slot section;
- the rolling disk rotates along the second friction board and the coil spring generates a repelling force towards the sliding direction when the guiding pole slides along the second slot section away from the first slot section.
A sliding mechanism, comprising:
- a body section;
- a cover section slidably mounted to the body section;
- a rolling disk fixed to the cover section;
- and
- a coil spring, a center of the coil spring fixed to a center of the rolling disk, an end of the coil spring fixed to a periphery of the rolling disk;
- wherein the coil spring generates a force towards or against a sliding direction of the cover section when the rolling disk rotates relative to the body section.
A sliding mechanism, comprising:
- a body section defining a sliding slot, the sliding slot including a first slot section and a second slot section, the first slot section offset with respect to the second slot section;
- a cover section slidably mounted to the body section;
- a rolling disk fixed to the cover section, a guiding pole protruding from a center of the rolling disk, the guiding pole slidably received in the sliding slot;
- a first friction board parallel secured on an edge of the first slot section;
- a second friction board parallel secured on an edge of the second slot section and opposite to the first friction board;
- and
- a coil spring, a center of the coil spring fixed to a center of the rolling disk, an end of the coil spring fixed to a periphery of the rolling disk;
- wherein the rolling disk rotates along the first friction board and the coil spring generates a resisting force against the sliding direction when the guiding pole slides along the first slot section to the second slot section;
- the rolling disk rotates along the second friction board and the coil spring generates a repelling force towards the sliding direction when the guiding pole slides along the second slot section away from the first slot section.
