Slide mechanism for slide-type portable electronic device

1. A slide mechanism, comprising:

a main plate forming two guiding groove portions;

a slide plate forming two guiding flanges engaging with the guiding groove portions respectively; and

a plurality of rollers, each of the rollers received in corresponding one guiding groove portion, directly contacting with the corresponding one guiding groove portion and the corresponding one guide flange, rolling along the corresponding one guiding groove portion and the corresponding one guide flange, to guide the guiding flanges to slide relative to the guiding groove portions;

wherein the slide mechanism includes two sleeves, the rollers are assembled in the sleeves and forms two guide bodies, the two guide bodies are assembled in the two guiding groove portions; and

wherein the sleeve includes a first clamp wall, a second clamp wall parallel with the first clamp wall, and a connecting wall perpendicularly connecting to the first clamp wall and the second clamp wall, all of which cooperatively enclose a space inside the sleeve and a receiving recess exposed to outside, the rollers are received in the space and comprises three arrays of rollers laterally arranged, the receiving recess receives the guide flange of the slide plate.

2. The slide mechanism as claimed in claim 1 , wherein the first clamp wall, the second clamp wall and the connecting wall define a plurality of through holes to hold the rollers.

3. The slide mechanism as claimed in claim 1 , wherein the slide mechanism includes an elastic member, the elastic member connects the main plate and the slide plate respectively.

4. The slide mechanism as claimed in claim 1 , wherein the main plate protrudes a guiding pole, the slide plate defines guiding hole, the main plate is attached to the slide plate, and the guiding pole engages with the guiding hole.

5. A slide mechanism, comprising:

a main plate forming two guiding groove portions;

a slide plate forming two guiding flanges; and

two guide bodies assembled with a plurality of rollers, the two guide bodies are assembled in the two guiding groove portions respectively, the guiding flanges engage with the two guiding groove portions and the rollers directly contacts with and rolls along the guiding flanges and the guiding groove portions to guide the guiding flanges to slide relative to the guiding groove portions;

wherein the guide body includes a sleeve, the sleeve includes a first clamp wall, a second clamp wall parallel with the first clamp wall and a connecting wall perpendicularly connecting to the first clamp wall and the second clamp wall, all of which cooperatively enclose a space inside the sleeve and a receiving recess exposed to outside, rollers are received in the space, the receiving recess receives the guide flange of the slide plate; wherein the rollers comprises three arrays of rollers laterally arranged.

6. The slide mechanism as claimed in claim 5 , wherein the first clamp wall, the second clamp wall and the connecting wall define a plurality of through holes, the holes are used to hold the rollers.

7. A portable electronic device, comprising:

a housing;

a cover; and

a slide mechanism engaged with the cover and housing and configured to drive the cover to slide relative to the housing,

wherein slide mechanism comprises a main plate forming two guiding groove portions and a slide plate forming two guiding flanges engaging with the guiding groove portions respectively, a plurality of rollers, the rollers are received in the guiding groove portions and directly contacts with and rolls along the guiding flanges and the guiding groove portions to guide the guiding flanges to slide relative to the guiding groove portions; and

wherein the slide mechanism includes two sleeves, the rollers are assembled in the sleeves and forms two guide bodies, the two guide bodies are assembled in the two guiding groove portions; wherein the sleeve includes a first clamp wall, a second clamp wall parallel with the first clamp wall, and a connecting wall perpendicularly connecting to the first clamp wall and the second clamp wall, all of which cooperatively enclose a space inside the sleeve and a receiving recess exposed to outside, the rollers are received in the space and comprises three arrays of rollers laterally arranged, the receiving recess receives the guide flange of the slide plate.

8. The portable electronic device as claimed in claim 7 , wherein the first clamp wall, the second clamp wall and the connecting wall define a plurality of through holes to hold the rollers.
