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
Generally need lay by the supporting frame on it when display screen uses and support and regulate the visual angle, therefore supporting frame is important conjunction and the matching parts of display screen interwoveness, reasonably support frame structure not only can provide a better more comfortable service condition to the user, also can set off out the better appearance and modeling of complete machine, make the operation of display screen can more ideally meet the requirement of ergonomics, minification is to greatest extent saved desk-top space simultaneously, quick detachable, be convenient to packing and carrying.
The display screen supporting frame is except a big class supporting frame class of the vertical support of table top, and another big class display screen is directly tiltedly to be placed on the table top to use, and namely adopts so-called photo frame type supporting way; Be that supporting frame is installed in the display screen back side, display floater and be arranged on the display screen back side or press close to arbitrary height position on the back side (comprising the embedding back side naturally) before the pivot axis position level of its leg and screen fastener and parallel and the display screen, modal be on the leg pivot axis at the display screen back side near the position of intermediate altitude and near the lower edge of the display screen back side position.When regulating the display screen angle of inclination, the leg lower edge then can be along slide on the desktop (pivot be at the whole desktop that reclines of then leg of screen lower edge), and forms triangular support jointly with computer lower edge (also can increase spike in the lower edge attaching); And in this class formation because of relate to leg whether need omnidistance tilt to support and have omnidistance and non-omnidistance two kinds take in the leg mode, the general leg of high-grade machine needs omnidistance angle support; Also have leg to take in to display screen back top with leg and take in the branch of (this leg generally is preferably shrinking structure, otherwise outward appearance is vulnerable to influence) to display screen back bottom.Because display screen all has certain weight, particularly one wherein touches the machine class, the main frame of its original split is integrated into the liquid crystal display back side in the lump increases the weight of weight, also to add hand touch screen power, therefore the mechanism of supporting frame inside want to realize display screen each position, angle of inclination leg of desktop can both balance, opposing lives the bigger weight component of display device and making a concerted effort of touch screen power and stablizes motionlessly, namely do not topple over automatically, lodge.
Existing have employing near its above-mentioned general structure of supporting frame technology of the present invention, and it realizes balance, the structure aspects of resisting above-mentioned power then all adopts suit torsion spring (also useful extension spring accommodation is installed and used) in rotating shaft, the torsion spring power that produces when being reversed with it is resisted, the main weight component of balance display screen, be set with pad constituent element such as bowl-type pad etc. in order to elastic compression leg and screen fastener toward contact routinely in the rotating shaft simultaneously, thereby further assist the weight component of torsion spring opposing display screen and utilize the frictional force characteristic of its generation to make screen be difficult for rocking to produce pressing friction power.But the shortcoming of the prior art maximum is owing to having adopted torsion spring and being to be sleeved in the thicker rotating shaft, and display screen can be given the rotating shaft length of installation often limited, the quantity that torsion spring is installed is also just limited, because wanting balance or the very big weight component of opposing display screen, so being very thick that spring filament diameter or whole coiled diameter all are compelled to do, torsion spring could produce enough balance counter-forces, cause complete machine to seem too fat to move especially in the outward appearance of local rotating shaft place, had a strong impact on the particularly frivolous sense of display screen complete machine aesthetic appearance, especially at present use more and more and heavier integrated machine display screen, 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 almost is fatal defective, also is unfavorable for dwindling to greatest extent the packaging volume space certainly; The ratio share that prior art has for this reason is forced to have to strengthen elasticity constituent element pressing friction power again reduces the size that torsion spring power proportion reduces torsion spring power more, but frictional force increases back leg when lifting screen can be taken up because of frictional force thereupon, need staff to go again to force to be pressed on the desktop, very inconvenient, It dones't help the situation so can only increase on a small quantity.More fatal is, this class supporting structure form leg rotation angle all exists this a great problem of what is called " mouse clip " phenomenon when big, namely after the relative display screen rotation of leg angle is big, this moment as unloaded release suddenly, spring can produce the high speed rebounce because of resilience suddenly, this is that the balance of unsettled, the no display screen gravity of leg when being used for spring that the balance screen weights is in tension and breaking away desktop because of leg because of this is resisted, can discharge at a high speed suddenly (similar mouse trap), it is more big to relatively rotate angle, impacts more severe; Because supporting frame is also connecting firmly display screen, high speed impact easily causes the display screen damage and produces the very big impact sound, and is also very dangerous to the people.There is the increasing of employing frictional force to alleviate its impact for this reason, the clear-cut structure that adopts axial compression frictional force without spring entirely or join a small amount of spring force at most again that What is more, but owing to all exist during the positive and negative rotation of frictional force, when lifting on the display screen, make leg also and then be taken up and taken away from desktop by frictional force, so have to when display screen lifts, need to pin leg with hand again, and the power of obviously pressing is that the weight component of screen adds frictional force again, namely almost be the screen gravity of nearly twice, such operation, firmly do not say, also Shi Fen inconvenience and the nature, particularly with gently, thin, fashion, advanced modern electric product uses feels extremely inharmonious.But up to the present, the problems referred to above never have good solution.
Therefore, this creator can improve thoughts on above-mentioned disappearance, is that the spy concentrates on studies and in conjunction with the application of scientific principle, proposes a kind of reasonable in design and invention of effectively solving above-mentioned disappearance finally.
Summary of the invention
Deficiency at above-mentioned prior art existence, the present invention seeks to be to provide a kind of photo frame type display screen supporting frame of brand new, realize that the display screen normal equilibrium supports, adjust the tilt angle and take in function such as leg, and leg can freely be pressed close to supporting surfaces such as desktop thereupon all the time when lifting display screen, thoroughly eliminate spring-like structure distinctive what is called " mouse trap " phenomenon or need the artificial factitious leg action link of pressing, make operation convenient, nature, for providing a more comfortable display screen, the user uses and operating environment, meet the ergonomics requirement better

Comprise at least one unidirectional rotary clutch 3, unidirectional rotary clutch 3 its titles are more, comprise as overrunning clutch, free wheel device, unilateral bearing, one-way clutch bearing, single direction ratchet, ratchet assembly etc., be a kind of known product and technology, its structure and principle are known in many fields such as machineries, also standardization of many parameters on its structure, a large amount of products in kind on market, on the net, data such as Machine Design class handbook or textbook all has detailed introduction and description, just repeat no more here.Though its kind is various, but external single effect power output connected related angle when unidirectional rotary clutch 3 used from it, mainly contain two parts, namely has common pivot axis, only can then be combined as a whole in the other direction to relative rotation with folk prescription each other can not a counterrotating first clutch rotating body 31 and a second clutch rotating body 32, and its actual first clutch rotating body 31 and a second clutch rotating body 32 material objects are mostly with in radially arranging, the structural type of the axial setting of the appearance of outer ring structure form or left axial end ratchet and right axial end ratchet occurs; Select in the structural type that its internal structure generally can be below comprising during actual use the or the classification: mainly contain the three major types pattern, engagement type, friction type and hybrid; Wherein friction type divides by wedge shape inner between its inside and outside circle and also comprises roller bearing, spin, contract piece, wedge watt or projection formula (starting the free wheel device of usefulness etc. as wherein modal one-way clutch bearing, motorcycle engine); Wherein engagement type also comprise radially engagement type (as the single direction ratchet at bicycle rear center) of band ratchet and not with ratchet axially engagement type (as diaxon lean on mutually spool the ratchet that is meshed of end face band) two class ratchets; Wherein be two kinds of the inner ring formulas of external tooth with the ratchet of the circular radial cylinder position of the radially engagement type ratchet that can be divided into the circular radial cylinder position of a clutch rotating body again of the ratchet outer ring type (as the single direction ratchet at bicycle rear center) that is internal tooth and a clutch rotating body; The ratchet-type of pawl-less then be two clutch rotating bodies on the axial axis end face that leans on mutually separately respectively all with the ratchet of mutual adaptive engagement; Wherein hybrid also comprise structure be the toothed working surface of voussoir with a clutch rotating body in the cylndrical surface upper toothed inner ring be meshed formula and with a clutch rotating body in the cylndrical surface be meshed two kinds of formulas of upper toothed outer ring, nature, the not toothed working surface of this voussoir then with another not toothed clutch rotating body cylndrical surface on directly friction mutually of the wedge shape type cavity surface that forms (for example common ratchet wrench namely be this hybrid combination).For ease of being shaped and keeping intensity, the ratchet that this example is above-mentioned and or ratchet and or voussoir and or wedge watt adopted and to have comprised the powder metallurgy shaping.
Select for use in the present embodiment with the first clutch rotating body 31 of the radially Internal and external cycle form work of setting and the hybrid overrunning clutch of a second clutch rotating body 32, then selecting among both one one linked to each other and be connected into that (the what is called here connects into sync-body for the synchronous interaction body of same pivot axis with this horizontal axis 7 with selecting of screen fastener 11 pivot parts 12 and leg 2 pivot parts 21, refer to it is the circumferentially energy one connection of rotation synchronously at least, certainly also comprise axial and circumferential all the fixedly connected one-body molded with both of one interlock be being connected of a part, specifically can adopt the axis hole of noncircular cross section adaptive, axle locks with the hole radial peg, axle locks with the axial end axial pin, axle is adaptive with the embedding of axial end convex-concave tooth, axis hole singly-bound spline class is adaptive, both are one-body molded to be integral piece, the affixed cooperation of axis hole interference, comprise that the connection that both direct adjunction between centers connect the techniques well known that is connected etc. all can, for describing for simplicity, in the document of the present invention all belong to this class connect all to be called for short connect into synchronous rotor or rotor synchronously); And it is above-mentioned through selecting another remaining this clutch rotating body and this screen fastener 1 pivot part 12 through selecting remainder or a person in leg 2 pivot parts 21, be one around these horizontal axis 7 rotations by synthetic this frictional force that both can rely on of the friction knot that compresses generation, can work as again when ordering about external force that both rotate each other greater than described frictional force maximum value, both can and overcome mutual sliding-frictional resistance and relatively rotate again each other around this horizontal axis 7; Be pivot axis, not only can rely on both unitary rotation of stiction but also overcome friction maximum value that both can be relatively rotated with the force of sliding friction value each other but also namely form with this horizontal axis 7.Described both compressing both can be that radial compaction with reference to this horizontal axis 7 also can be axial compression, both can be that both direct contacts compress, also can be both by other part compress mutually compress indirectly; Direct radial compaction serves as flexibly coat of angle of spot hole look direct such as one individual among both and oppresses compressing of another part formation of respectively serving as the rotating shaft role, resembling and producing compressing of required frictional force between pivotal axis commonly used in the notebook computer bracket in the art and the pivoting hole namely is flexibly to pack tightly compressing of axle generation by this type of form structure by the hole, and then produces frictional force; Certainly, also can use the industry method that axially produces frictional force indirectly the most commonly used, namely by suit above the axle both and simultaneously suit pad constituent element 5(such as packing ring, elastic washer 51, nut 52 etc., each packing ring comprises non-circular hole) etc. screw each part of compression, make to form indirect impacting force between the two and produce frictional force then.
Obviously first clutch rotating body and two has only relative meaning, but be noted that because the unidirectional relatively revolving property of unidirectional rotary clutch 3, the selection of its unidirectional sense of rotation should be arranged to should be in bonding state when display screen top this unidirectional rotary clutch 3 when verting to its screen behind direction when each unidirectional rotary clutch 3 was installed at this horizontal axis 7, namely first clutch rotating body 31, second clutch rotating body 32 both be in unidirectional sense of rotation in relative rotation; Also namely force two to produce between the part that rubs and to relatively rotate each other, because of interaction relation also namely mean screen fastener 1 and leg 2 relative between (noticing that frictional force is not to be created between the two) can not relatively rotate this moment (suppose aforesaid impacting force generation the setting of stiction value with support, balance is firmly shielded making a concerted effort quite of partical gravity and a small amount of hand touch screen power), have only continuation to strengthen hand pressure by force up to making a concerted effort of applying during greater than the maximum static friction force of this setting, just can make two to produce and to overcome sliding friction each other between the part of friction and relatively rotate, also namely both occur relatively rotating each other because of interaction relation screen fastener 1 and leg 2, realized namely that also downward adjustment shields new angular orientation, and adjust upward screen again during the angular orientation when lifting the screen upper limb, unidirectional rotary clutch 3 is in separated state at this moment, two clutch rotating bodies be in can be each other unidirectional sense of rotation in relative rotation, make leg 2 even rely on self leg 2 gravity can shield freedom relatively to paste sliding on table top downwards all the time.For understanding conveniently, more than totally also can think roughly because the use of unidirectional rotary clutch 3 has realized unidirectional sliding friction function.
As previously mentioned, being used for realizing that compressing the mode that produces frictional force can be that radial compaction also can be axial compression, can be that both directly compress, and also can be both indirect compressing.Wherein radially directly compress specifically like this realization as adopting: thus leg 2 pin-joint parts 21 or shield fastener 11 pin-joint part alternatively persons and offer on it and have that pass through openings 61 do not seal, with this horizontal axis 7 horizontal pivoting hole that is pivot axis, be provided with a pivotal axis 4 in this horizontal pivoting hole, and these horizontal pivot axis 4 outer round surface and this horizontal pivoting hole internal circular surfaces by select to coat suitable the cooperating of tightness make form between the two the radial elastic impacting force (as the magnitude of interference of control hole and axle and or the rigidity of hole material, known impacting force regulating method such as elastic force), stop both stiction and make both be one interlock shape in relative rotation each other thereby when ordering about the external force that both rotate mutually, can produce, mutual but also can relatively rotate to overcome mutual force of sliding friction around this horizontal axis 7 in the time of work as not only described external force greater than predetermined this stiction maximum value; This pivotal axis 4 is in outside the horizontal pivoting hole that is wrapped by one one and is interconnected to synchronous rotor with one of clutch rotating body person, and another clutch rotating body then with through selecting one after remaining another shields one of fastener 1 pivot part 12 or leg 2 pivot parts 21 person and links to each other and be connected into synchronous rotor.
Coat impacting force to obtain the friction force value of predetermined required size for ease of adjusting, described opening 6 is sentenced tabular edge away from one section of the radially extension of this horizontal axis 7, add known fastening and the technology of regulating impacting force such as nut at these two tabular sections 62 fastening pieces 63 that at least one adjustable impacting force is set as screw or screw then, the radial elastic impacting force that makes this horizontal pivoting hole coat this pivotal axis 4 is regulated, and the frictional force that also namely is equivalent to produce is then regulated.
And axial compressing indirectly specifically also can realize like this: the method that produces frictional force by related domain two parts commonly used, namely adopt pad constituent element 5, this pad constituent element comprises that at least one elastic washer 51, at least one nut 52(that locks are better as the plain washer that adds at least one band non-circular hole); Connect into synchronous rotor with one one of this drive-connecting shaft 4 with one of this two clutches rotating body person, another one of this drive-connecting shaft 4 then is inserted in these pad constituent element 5 each part center holes pivotally and selects the perforation circular hole that these leg 2 pivot parts 21 of selecting maybe are provided with among one of this screen fastener 1 pivot part 12 person in the heart, and by this lock nut 52 axial elasticities compress these pad constituent element 5 each parts and and then together compress through selecting these leg 2 pivot parts 21 of selecting maybe on one of this screen fastener 1 pivot part 12 person, thereby through selecting the frictional force that this pivot part of one and this drive-connecting shaft 4 exert an influence and whether rotate mutually between the two between the two, also namely form when ordering about the external force that both rotate mutually, can produce and stop the stiction that both rotate mutually and make both be one interlock shape, in the time of working as described external force greater than predetermined this stiction maximum value again, both can relatively rotate to overcome mutual force of sliding friction around this horizontal axis 7 again each other; Another clutch rotating body then with through select after one another remaining these leg 2 pivot parts 21 maybe one of this screen fastener 1 pivot part 12 person connect into synchronous rotor;
In addition simultaneously especially referring to Fig. 3 and Fig. 4, screen fastener 1 pivot part 12 described above and or these leg 2 pivot parts 21 all can be branched into again about two pivot ears and the hole is set in these horizontal axis 7 positions.Also namely be equivalent to but many more than two pairs screen fastener 1 or the pivot part 21 of leg 2, can go structure and the spare part of reusing aforesaid enforcement again, so that improve support stiffness and be convenient to installation; General normal symmetry is installed two these spare parts of cover and structure etc.; Because of just repeatability installation enforcement simply, just do not given unnecessary details here.
The present invention is by creatively having installed unidirectional rotary clutch and disposable pressing friction rotating force that the industry never adopted, and can cancel with spring force as main equilibrant, overcome at one stroke all defect of prior art for this reason, realized that the display screen normal equilibrium supports, adjust the tilt angle and take in function such as leg, but thoroughly eliminated the spring-like structure distinctive unexpected when unloaded the high speed of spring discharge what is called " mouse trap effect " this a great problem of recoil, leg can easily freely be pressed close to supporting surfaces such as table top thereupon all the time when lifting display screen, avoided effort, burdensome and factitious hand is pressed the leg action link, operate light, save trouble, nature, for providing a more comfortable display screen, the user uses and operating environment, met the ergonomics requirement well, and had simple in structure, characteristics such as easy realization.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
