Abstract

The utility model relates to a display screen supporting frame with an adjustable dip angle. In the prior art, the weight of a screen is balanced mainly in the mode that a supporting foot rotating shaft is sleeved with a torsion spring. The mode has the defects that the torsion spring must be very thick and large, the beauty of the appearance of the whole screen is seriously affected, and the hand feel is poor. Particularly, the 'mouse trap' phenomenon that a supporting foot bounces at a high speed exists, or when the screen is lifted up, the supporting foot is also lifted by friction force, as a result, the supporting foot needs to be pressed with hands behind the screen, and the operation is quite inconvenient and unnatural. According to the display screen supporting frame with the adjustable dip angle, a unidirectional rotation clutch is used and rotation friction is converted to eliminate the situation that spring force serves as main balance force, therefore, lots of defects of the prior art are overcome at one stroke, and normal and balanced support of the screen, the adjustment of the dip angle, the folding of the supporting foot and other functions are achieved. When the screen is lifted, the supporting foot can always be attached to a table top, therefore, the 'mouse trap' phenomenon peculiar to a spring structure or the unnatural action that the supporting foot is pressed by hand is eliminated thoroughly, the operation is natural and convenient, and a more comfortable using and operating environment is provided for a user.

Description

A kind of display screen supporting frame of adjustable inclination angle

Technical field

The utility model relates to a kind of display screen supporting frame, what be specifically related to is a kind of display screen supporting frame of photo frame type adjustable inclination angle.

Background technique

Display screen with the time generally need to lay by the supporting frame on it and support and adjustable 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 large class supporting frame class of the vertical support of table top, and another large 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 (naturally comprising the embedding back side) 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 jointly forms triangular support 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 dividing of (this leg generally being preferably shrinking structure, otherwise outward appearance is vulnerable to impact) to display screen back bottom.Because display screen all has certain weight, particularly wherein one 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 live the larger weight component of display device and making a concerted effort of touch screen power and stablize motionless, i.e. not Automatic-dumping, lodging.

Existing have employing near its above-mentioned general structure of supporting frame technology of the present utility model, and it realizes balance, the structure aspects of resisting above-mentioned power then all adopts and is set with 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 simultaneously rotating shaft, 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 large 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, certainly also is unfavorable for dwindling to greatest extent the packaging volume space; The ratio share that prior art has for this reason is forced to again to have to strengthen elasticity constituent element pressing friction power reduces the size that torsion spring power proportion reduces torsion spring power more, but after frictional force increases when lifting screen leg 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 large, namely after the relative display screen rotation of leg angle is large, this moment as suddenly unloaded release, spring can produce the high speed rebounce because of suddenly resilience, this be when being used for spring that the balance screen weights is in tension and breaking away desktop because of leg because of this leg unsettled, without the balance opposing of display screen gravity, meeting unexpected high speed pay-out (similar mouse trap), it is larger 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 large 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 entirely adopts axial compression frictional force without spring or join again at most a small amount of spring force that What is more, but all exist during owing to the positive and negative rotation of frictional force, when lifting on the display screen so that leg also and then 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 very 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, finally proposes a kind of reasonable in design and effectively solve the model utility of above-mentioned disappearance.

Comprise at least one single direction rotation clutch 3, single direction rotation clutch 3 its titles are more, comprise such as overrunning clutch, free wheel device, unilateral bearing, one-way clutch bearing, single direction ratchet, ratchet assembly etc., 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, the 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 single direction rotation clutch 3 when it uses externally Unidirectional acting force output connect related angle, mainly contain two parts, namely has common pivot axis, each other only can with one direction relatively rotation then be combined as a whole in the other direction can not a counterrotating first clutch rotating body 31 and a second clutch rotating body 32, 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. such as wherein modal one-way clutch bearing, motorcycle engine); Wherein engagement type also comprise with radially engagement type (such as the single direction ratchet at bicycle rear center) of ratchet with not with axially engagement type (ratchet that the end face band of the axle that leans on mutually such as diaxon is meshed) two class ratchets of ratchet; Wherein be two kinds of the interior ring types of external tooth with the ratchet of the circular radial cylinder position of the radially engagement type ratchet that can be divided into again the circular radial cylinder position of a clutch rotating body of the ratchet outer ring type (such 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 the directly mutually friction (for example common ratchet wrench namely is this hybrid combination) of the wedge shape type cavity surface that forms.For ease of being shaped and keeping intensity, the ratchet that this example is above-mentioned and or ratchet and or voussoir reaches or wedge watt has adopted and to comprise powder metallurgy formation.

Select 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 the one of selecting of selecting one and screen fastener 11 pivot parts 12 and leg 2 pivot parts 21 among both is linked to each other and is connected into synchronous interaction body take this horizontal axis 7 as same pivot axis (the what is called here connects into sync-body, refer to it is the circumferentially connection of energy integrated synchronous rotation at least, certainly also comprise axial and circumferential all the one interlock to be fixedly connected with being connected one-body molded be the connection of a part, specifically can adopt the axis hole of noncircular cross section adaptive, axle and hole radial peg lock, axle and axial end axial pin lock, axle and axial end convex-concave dental inlay are adaptive, axis hole singly-bound spline class is adaptive, both one-body molded parts that are integrated, 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 utility model document all belong to this class connect all to be called for short connect into synchronous rotating kinetoplast or synchronous rotating kinetoplast); 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 compressing synthetic this frictional force that both can rely on of the friction knot that produces, 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 around this horizontal axis 7 again each other; But also namely form take this horizontal axis 7 as 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.Described both compression both can be that the radial compaction with reference to this horizontal axis 7 also can be axial compression, both can be that both direct contacts compress, and also can be the indirect compression of both mutual compressions of passing through other part; Directly radial compaction serves as the angle of spot hole look direct compression of oppressing another part formation of respectively serving as the rotating shaft role that flexibly coats such as one individual among both, resembling the compression that produces 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 the compression that axle produces by this type of form structure by the hole, and then produces frictional force; Certainly, also can use the industry method that axially indirectly produces frictional force the most commonly used, namely by suit above the axle both and be set with simultaneously 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 then produce frictional force.

Obviously first clutch rotating body and two only has relative meaning, but be noted that because the relative single direction rotation characteristic of single direction rotation clutch 3, the selection of its single direction rotation direction should be arranged to should be in bonding state when display screen top this single direction rotation clutch 3 when verting to its screen behind direction when each single direction rotation clutch 3 was installed at this horizontal axis 7, namely first clutch rotating body 31, second clutch rotating body 32 both be in relative rotation single direction rotation direction; 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), only have continuation to strengthen hand pressure by force until 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 again adjust upward screen during the angular orientation when lifting the screen upper limb, single direction rotation clutch 3 is in separated state at this moment, two clutch rotating bodies be in can be each other single direction rotation direction in relative rotation so that leg 2 even rely on self leg 2 gravity relatively to shield freely to paste all the time sliding on table top downwards.For understanding conveniently, more than totally also can think roughly because the use of single direction rotation 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 that both indirectly compress.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, horizontal pivoting hole take this horizontal axis 7 as 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 make and form the radial elastic impacting force between the two and (reach or the rigidity of hole material such as the magnitude of interference of control hole and axle by selecting to coat suitable the cooperating of tightness, the known impacting force regulating method such as elastic force), thereby stop both each other stiction and make both be one interlock shape in relative rotation when having can produce when ordering about the external force that both rotate mutually, 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; The one with the clutch rotating body that this pivotal axis 4 is in outside the horizontal pivoting hole that is wrapped by is interconnected to the synchronous rotating kinetoplast, and another clutch rotating body then with through selecting another remaining after one screen fastener 1 pivot part 12 or the one of leg 2 pivot parts 21 is connected into the synchronous rotating kinetoplast.

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, then add the known fastening technology with regulating impacting force such as nut at these two tabular sections 62 fastening pieces 63 that at least one adjustable impacting force is set such as screw or screw, 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 then produce is regulated.

And axial indirect compression 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 at least one elastic washer 51, at least one to lock nut 52(better as adding at least one plain washer with non-circular hole); One with this two clutches rotating body of this drive-connecting shaft 4 is connected into the synchronous rotating kinetoplast, another one of this drive-connecting shaft 4 then is inserted in pivotally these pad constituent element 5 each part center holes and selects the maybe perforation circular hole that is provided with of the one center of this screen fastener 1 pivot part 12 of these leg 2 pivot parts 21 of selecting, 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 the one of this screen fastener 1 pivot part 12, thereby the frictional force that exerts an influence between the two and mutually whether rotate between the two at this pivot part through selecting one and this drive-connecting shaft 4, also namely form when having to produce when ordering about the external force that both rotate mutually and stop the stiction that both rotate mutually and make both be the one shape that links, in the time of working as again described external force greater than predetermined this stiction maximum value, 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 the one of this screen fastener 1 pivot part 12 connect into the synchronous rotating kinetoplast;

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 again structure and the spare part of reusing aforesaid enforcement, so that improve support stiffness and be convenient to installation; General normal symmetrical two these spare parts of cover and the structure etc. of installing; Because of just simply repeatability installation enforcement, just do not given unnecessary details here.

The utility model is by creatively having installed single direction rotation 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 the function such as leg, this a great problem of what is called " mouse trap effect " of the high speed pay-out recoil of spring when but thoroughly having eliminated the distinctive unexpected zero load of spring-like structure, leg can easily freely be pressed close to the 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 well the ergonomics requirement, and had simple in structure, the characteristics such as easy realization.
