Description
Technical field
The utility model relates to many stop rotating shaft structures, and especially it articulates the turning shaft structure of frame with many backstop restriction opening angle functions and automatic blocking function, is applicable to cover-lifting type electronic device.
Background technique
In order to limit the screen opening angle, generally be used for the rotating shaft of drawing-pushing type electronic product such as the rotating shaft regular meeting of notebook stop configurations is set in rotating shaft, locate with backstop and limit screen and after opening an angle, can't continue to overturn backward.
Prior art is as shown in Taiwan utility model patent notification number M303606 " can limit the pivot that starts angle ", it is arranged between the display screen and body of folding electron product, comprise: base, be fixed on the body of folding electron product and be provided with a circular hole, the surface below of this circular hole forms a block; Supporting frame is fixed on the display screen of folding electron product; Rotating shaft has with the joint of supporting frame winding and passes the axial region of base circular hole; The shell fragment group, be positioned on the axial region of rotating shaft and rotating shaft axially on compressing power is provided; The friction wheels are arranged on the rotating shaft axial region, produce resistance so that be fixed on the display screen of folding electron product supporting structure relatively folding electron product body amount to or open with unspecified angle; The backstop cam, having perforation and passing and can rotate together for the axial region of above-mentioned rotating shaft, and having sector part in outer rim, a side of above-mentioned backstop cam sector part can contact with the block below the circular hole of base when rotating shaft is rotated, reach backstop action, can limit the flip angle of pivot.
Though above-mentioned prior art can reach the backstop effect, but only come the backstop screen by the block that protrudes, the backstop insufficient strength is repeatedly using the back to damage easily.
Another prior art is shown in Taiwan utility model patent notification number M345152 " pivot of the two retaining points of single bolster ", it mainly is respectively equipped with the first outstanding block and second block on the tabs bi-side of passing for axial region on the single bolster of pivot, first and second limit assembly that together rotates with axial region is divided into the bi-side of tabs, and each limit assembly has first and second blocked part respectively.When pivot was opened to maximum angle, first blocked part can offset with first block, and second blocked part can offset with second block, limits the rotating shaft of pivot and the maximum angle that support rotates relative to pedestal thus jointly.
Above-mentioned known structure is respectively established a block with the two sides of bolster and is come backstop, though can improve backstop intensity, need to increase limit assembly, and when assembling easily because of the direction assembly defect of limit assembly, still be not very desirable therefore.
In addition, rotating shaft with automatic blocking function normally realizes by the cam of sheathed two mutual chimeric location on the axle, shown in the Taiwan model utility notification number M296586 " turning shaft structure of tool automatic blocking " that this case claimant is had, it has the cam member of being made up of fixed block and slider, fixed block is fixed on the body frame body, slider is fixed on axis bar, when axis bar rotates, the wedge slot inclined-plane of this slider moves on fixed block wedge-shaped blocks inclined-plane, thereby axial compression elastomer, and the contact plane of slider can be rotated along each wedge-shaped blocks of fixed block, and when counter-rotating, each wedge slot of this slider moves to each wedge-shaped blocks of fixed block, then by the elastomer extensional process, each wedge slot is buckled in each wedge-shaped blocks, thereby form the automatic blocking of butt joint.
Rotating shaft commonly used function in order to reach automatic blocking and to improve backstop intensity must be provided with more part, thereby can't reduce cost, and structure is also comparatively complicated, and assembling is difficulty comparatively.
