Description
Technical field
What the present invention relates to is a kind of display screen supporting frame, and what be specifically related to is a kind of display screen supporting frame of photo frame type adjustable inclination angle.
Background technique
Display screen generally needs when using to lay support and adjustable visual angle by the supporting frame on it, therefore supporting frame is important conjunction and the matching parts of display screen interwoveness, rational support frame structure not only can provide a better more comfortable service condition to user, also the better appearance and modeling of complete machine can be set off out, make the operation of display screen more ideally can meet the requirement of ergonomics, simultaneously minification to greatest extent, save desk-top space, quick detachable, be convenient to packaging and carrying.
Display screen supporting frame is except a large class supporting frame class of table top vertical support, and another large class display screen is directly tiltedly placed on table top to use, and namely adopts so-called photo frame type supporting way; Namely supporting frame is arranged on the display screen back side, the pivot axis position level of its leg and screen fastener and parallel with display screen before display floater be arranged on the display screen back side or press close to the arbitrary height position on the back side (naturally comprise embed the back side), modal be leg upper end pivot axis at the display screen back side close to the position of intermediate altitude and near the lower edge of the display screen back side position.When regulating display screen angle of inclination, leg lower edge then along desktop slides (pivot is at the whole desktop that reclines of then leg of screen lower edge), and can form triangular support with computer lower edge (also can increase spike in lower edge attaching) jointly; And whether need omnidistance inclined shore because relating to leg and have omnidistance and non-omnidistance two kinds of storage leg modes in this class formation, the general leg of high-grade machine needs omnidistance angle to support; Leg is also had to receive dividing of (this leg being generally preferably shrinking structure, otherwise outward appearance is vulnerable to affect) to the storage of display screen back top and leg to display screen lower back.Because display screen all has certain weight, particularly one wherein touches machine class, the main frame of its original split is integrated into the liquid crystal display back side in the lump makes weight penalty, also to add hand touch screen power, therefore the mechanism of supporting frame inside wants to realize display screen and can balance at desktop each oblique angular position leg, resist making a concerted effort and stablize motionless, be i.e. not Automatic-dumping, lodging of the larger weight component of display device and touch screen power.
Existing its above-mentioned general structure closest to supporting frame technology of the present invention has employing, and it realizes balance, the configuration aspects of resisting above-mentioned power then all adopts in rotating shaft, is set with torsion spring (also useful extension spring accommodation is installed and used), the torsion spring force produced when being reversed with it is resisted, the main weight component of balance display screen, simultaneously rotating shaft is set with pad constituent element if bowl-type pad etc. is in order to elastic compression leg and screen fastener toward contact routinely, to produce pressing friction power thus to assist further the weight component of torsion spring opposing display screen and the friction characteristics utilizing it to produce makes screen not easily rock.But the maximum shortcoming of the prior art is owing to have employed torsion spring and is be sleeved in thicker rotating shaft, and display screen can given rotating shaft length of installation often limited, the quantity that torsion spring is installed is also just limited, because balancing or resist the very large weight component of display screen, therefore torsion spring is spring filament diameter or entirety is coiled into very thick that diameter is all compelled to do and could produces enough balance counter-forces, complete machine is caused to seem too fat to move especially in the outward appearance of local rotating shaft place, have a strong impact on the particularly frivolous sense of display screen complete machine aesthetic appearance, especially at present more and more and heavier integrated machine display screen is used, its torsion spring will be thicker, situation is more serious, particularly ultra-thin to more and more pursuing at present, the machine requirement of fashion, this is almost fatal defect, certainly be also unfavorable for reducing packaging volume space to greatest extent, the proportionate share that what prior art had for this reason be forced to again has to strengthen elasticity constituent element pressing friction power reduces torsion spring power proportion more to reduce the size of torsion spring power, but when lifting screen, leg can be taken up because of frictional force after frictional force increases thereupon, staff is needed to go pressure to be pressed on desktop again, very inconvenient, therefore can only to increase on a small quantity and It dones't help the situation.More fatal is, this kind of supporting structure form leg rotation angle all also exists this great problem of what is called " mouse clip " phenomenon time large, namely after leg relative display screen rotation angle is comparatively large, now as unloaded release suddenly, spring can produce high speed rebounce because of unexpected resilience, this be because of this spring being in tension for balancing screen weights because of leg break away desktop time leg unsettled, resist without the heavy equilibrium of forces of display screen, the unexpected high speed pay-out of meeting (similar mouse trap), relatively rotate angle larger, impact more severe; Because supporting frame also connects firmly display screen, high speed impact easily causes display screen to damage and produces the very large impact sound, also very dangerous to people.Have to adopt for this reason and strengthen frictional force to alleviate its impact, the clear-cut structure entirely adopting axial compression frictional force without spring or join a small amount of spring force at most again that What is more, but all exist during rotation positive and negative in frictional force, make leg also and then be taken up and taken away from desktop by frictional force when display screen is lifted, therefore have to when display screen lifts, leg need be pinned again with hand, and the weight component that the power of obviously pressing is screen adds frictional force again, namely be almost the screen gravity of nearly twice, such operation, firmly do not say, also inconvenience very and nature, particularly with gently, thin, fashion, advanced modern electrical product uses feels extremely inharmonious.But up to the present, the problems referred to above never good solution.
Therefore, this creator can improve thoughts on above-mentioned disappearance, is that spy concentrates on studies and combines the application of scientific principle, finally proposes a kind of reasonable in design and effectively solve the invention of above-mentioned disappearance.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the present invention seeks to the photo frame type display screen supporting frame being to provide a kind of brand new, realize display screen normal equilibrium to support, the functions such as adjustment tilt angle and storage leg, and leg freely can press close to the supporting surfaces such as desktop all the time when lifting display screen thereupon, thorough elimination spring like structure distinctive what is called " mouse trap " phenomenon or the artificial factitious pressing leg action link of need, make operation convenient, nature, for user provides a more comfortable display screen to use and operating environment, meet ergonomic demands better,
