Abstract
Description
- The exemplary disclosure generally relates to sliding mechanisms, and particularly, to a sliding mechanism used in a portable electronic device.
- Slide-type portable electronic devices usually include a main housing, a slidable housing, and a sliding mechanism. The sliding mechanism drives the slidable housing to slide with respect to the main housing.
- The sliding mechanism usually includes a body section, a cover section, and a torsion spring. One end of the torsion spring is fixed to the body section, and the other end of the torsion spring is fixed to the cover section. The cover section can slide relative to the body section by releasing the torsion force of the torsion spring. Due to the main housing and the slidable housing being fixed to the body section and the cover section, the slidable housing can slide relative to the main housing.
- However, after repeated use, the torsion spring may wear out and fail to function properly, thereby degrading the sliding mechanism.
- Therefore, there is room for improvement within the art.
- Many aspects of the sliding mechanism can be better understood with reference to the following drawings. These drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present sliding mechanism. Moreover, in the drawings like reference numerals designate corresponding sections throughout the several views.

FIG. 1 andFIG. 2 , anexemplary sliding mechanism 100 for portable electronic devices, such as mobile phones, digital cameras and etc., is shown. Thesliding mechanism 100 includes afixed piece 10, asliding piece 30, and afriction reducing assembly 50. Thefixed piece 10 may be made of metal. Thefixed piece 10 includes amain body 11 and two slidingrails 13 disposed on themain body 11. Referring also toFIG. 4 , themain body 11 has a U-shaped cross-section, and includes amain board 111 and two assemblingwalls 113. The two assemblingwalls 113 are disposed at two opposite edges of themain board 111 and are parallel to each other. The two slidingrails 13 are bar-shaped, and made of a strong material such as metal. The slidingrails 13 both include an inner surface (not figured) and agroove 132. The two inner surfaces are disposed facing each other. Eachgroove 132 is recessed in a corresponding inner surface 131 therethrough, and extends longitudinally along the inner surface. In the present embodiment, the two slidingrails 13 are formed by extrusion, and are welded to corresponding assemblingwalls 113. The two slidingrails 13 and themain body 11 together form a substantially rectangular assemblingspace 15 therebetween, so as to accommodate thesliding piece 30 and thefriction reducing assembly 50. - The
sliding piece 30 has a U-shaped cross-section and includes abase 31 and two guidingrails 33 disposed at two opposite edges of thebase 31 corresponding to the two slidingrails 13 respectively. The two guidingrails 33 are parallel to each other and are configured to slidably engage with the two slidingrails 13 of themain body 11 respectively. The two guidingrails 33 are bar-shaped and made of a strong material such as metal. Each guidingrail 33 includes an outer surface (not shown) and a guidinggroove 332. The two outer surfaces are disposed facing away from each other. Each guidinggroove 332 is recessed in a corresponding outer surface therethrough, and extends longitudinally along the outer surface. In the present embodiment, the two guidingrails 33 are formed by extrusion, and are welded to the corresponding two opposite edges of thebase 31. The two guidinggrooves 332 are facing away from each other. Thesliding piece 30 is slidably assembled and accommodated within the assemblingspace 15 of thefixed piece 10. The two guidingrails 33 of thesliding piece 30 are slidably assembled with the two slidingrails 13 of thefixed piece 10 respectively and form twocylindrical holes 40 there-between. - Also referring to
FIG. 3 , thefriction reducing assembly 50 is disposed between and in rolling contact with thesliding rails 13 and the guidingrails 33, so as to reduce the friction between thesliding piece 30 and thefixed piece 10. Thefriction reducing assembly 50 includes twobackstops 51 and a plurality ofballs 53. Eachbackstop 51 includes amain portion 511, abent portion 512 bent from a longitudinal edge of themain portion 511, and a plurality oftabs 5115. Themain portion 511 includes a plurality of equally spaced throughholes 5111 defined therethrough along the longitudinal direction. The other longitudinal edge of themain portion 511 opposite to thebent portion 512 defines a plurality ofgaps 5112 therethrough. Eachgap 5112 communicates with a corresponding throughhole 5111. Thetabs 5115 extend out from two opposite sides of themain portion 511. Each throughhole 5111 is surrounded by four equallyspaced tabs 5115. Theballs 53 loosely fit in the throughholes 5111, and are prevented from dropping off thebackstop 51 by thetabs 5115. - Also referring to
FIG. 4 andFIG. 5 , in assembly, the twobackstops 51 are assembled within the two slidingrails 13 of thefixed piece 10 respectively, with thebent portion 512 projecting out of the corresponding slidingrail 13. The plurality of theballs 53 are assembled within the corresponding throughholes 511 of thebackstop 51 and partially accommodated within the correspondingsliding rail 13 of thefixed piece 10. Thesliding piece 30 is slidably assembled with thefixed piece 10, with the two guidingrails 33 assembled to the two slidingrails 13 of thefixed piece 10. Thefriction reducing assemblies 50 are clamped between the corresponding guidingrail 33 and slidingrail 13. In use, thesliding piece 30 is driven to slide relative to thefixed piece 10, theballs 53 jointly rotate relative to thesliding piece 30 and thefixed piece 10. Therefore, thefriction reducing assembly 50 rollingly contacts both thesliding piece 30 and thefixed piece 10 which reduces friction therebetween. - The
sliding mechanism 100 could be used in a portable electronic device, wherein, the portable electronic device includes a main body, asliding mechanism 100, and a sliding body. Thefixed piece 10 is assembled with main body of the portable electronic device, and thesliding piece 30 is assembled with the sliding body, so that the sliding body is slidably assembled with the main body. - It is to be understood that the
fixed piece 10 and thesliding piece 30 could be produced by one-mold molding method. - It is to be understood, however, that even through numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of sections within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms, in which the appended claims are expressed.
