Description
Technical field
The present invention refers to that especially a kind of support object that makes remains on state of equilibrium, and reaches the balance arm component that makes this holder have the effect that is easy to move relevant for a kind of balance arm component.
Background technique
Existing many at present application examples adopt transfer arm to support one or more objects.For example,, office, medical space or other place, there are many disclosed this structures to support lamp at home with one or more link arms.Still there are some link arm structures to be used for supporting the amplification design of multiple size, weight or structure in addition.Moreover, also have some arm configurations can be used for especially adjusting and support computer monitor or similar goods.
In the arm configuration of all these, common purpose the most basic is exactly the position of adjusting one or more arms, make it support fixture a needed equilibrium position, the one or more arms of indication can be set at a position of interior different amount on a large scale here.The basic goal of considering still can utilize minimum locomotivity to adjust one or more arms, it is arranged on certain angle, even the fixture weight ratio that is supported is bigger.Therefore, the artificers of this technical field are exploring a kind of energy of exploitation fixing object for many years in any one equilibrium position always, the angle of equilibrium position can infinitely change, and can make object move to the robot arm device of another equilibrium position from an equilibrium position with the mobile strength of minimum.
Yet, many results prove that the robot arm device of creating a kind of like this ideal operation is difficult for, and the inventor of a lot of industries met this problem, when the angle of supporting arm relatively vertically changes, require to be used for supporting that object also will inevitably change at the holding power of a state of equilibrium.In the mechanical arm structure, the angular orientation of supporting arm increases gradually or when reducing, it changes on nonlinear sinusoidal curve, so deal with very difficulty of this variable force square with this arm.
A large amount of existing equipments are arm configurations of a parallelogram shape of design, but provide the equilibrant that needs, for example spring or elastomeric objects with the object of one or more elastic compression or extension.Because the resistance that spring provides can increase or reduce this needed strength of support object that is used for adapting to, so this spring structure is effective to a certain extent.But spring is in elastic range, and strength and elasticity coefficient that stretching, extension or compression need are proportional.Therefore, when supporting arm was mobile in a given angular range, the linear resistance that clog-free spring applied of certain-length can not corresponding be supported the non-linear downward active force of object.
Relatively, even the spring structure specialized designs is used for supporting a given weight, spring still might provide unnecessary resistance to the one or more parts in the supporting arm range of movement, and provides less resistance to other parts of supporting arm range of movement.Therefore, produce one can support object on a large scale under the angle supporting arm structure of balance be really quite the difficulty.
Also have a lot of subjects under discussion and imagination to make the design of balance supporting arm and manufacturing become complicated more.A kind of important imagination is the object that the consideration balance arm must be supported Different Weight.In some designs, must use the spring of multiple different elasticity coefficient to support the object of Different Weight.But clearly, this design implements very complicated.For example, the manufacturer must keep the spring stock that might use, the very little spring of the difference of will avoiding confusion in addition.Another kind of design be electric power through being commonly used to the holder body, wherein electric wire must vertically cross supporting arm, can influence the aesthetic feeling of arm, also may interfere the function of arm.More also have many designs, each arm is located at one by on a plurality of contractile external formed parallelogram, but like this user is had potential danger.
In sum, obviously, industry needs a kind of arm configuration of certain submissiveness, and it can move with the power of minimum, simultaneously in angle on a large scale, and the nonlinear change that second supporting arm can the adaptive faculty moment arm.In addition, the arm configuration of compliance need adapt to the object of Different Weight, will avoid also seeing that electric wire exposes or damages electric wire and the operator is produced danger.Furtherly, the arm configuration of compliance should satisfy above-mentioned needs, has the advantage of representing this remarkable superiority in field again.

See also shown in Fig. 1,2,3, be respectively the sectional view of balance arm of the present invention, the sectional view of the present invention's second supporting arm and the balance exercise schematic representation of the present invention's second supporting arm.As shown in the figure: the present invention is a kind of balance arm component, and second supporting arm 12 of this balance arm 10 is articulated on the second supporting arm link 18 around terminal drive-connecting shaft 38, and simultaneously, the intermediate connector 16 and second supporting arm 12 articulate on far-end drive-connecting shaft 49 mutually.Second supporting arm 12 is provided with first control arm 28 and second control arm 30, and its end is articulated on the second supporting arm link 18, and far-end is articulated on the intermediate connector 16.More particularly, the end of first control arm 28 is articulated on the second supporting arm link 18 by drive-connecting shaft 46, and the far-end of first control arm 28 is articulated on the intermediate connector 16 by drive-connecting shaft 50.Similarly, the end of second control arm 30 is articulated on the second supporting arm link 18 by drive-connecting shaft 44, and the far-end of second control arm 30 is articulated on the intermediate connector 16 by drive-connecting shaft 48.Therefore, first control arm 28 and second control arm, 30, the second supporting arm links 18 and intermediate connector 16 form a parallelogram sturcutre by drive-connecting shaft 44,46,48,50 definition together.
In this illustrated embodiment, second spring 24 is the coiling spring, is connected to first control arm 28 by its far-end 43, and the end 47 of second spring 24 is connected to the second supporting arm link 18, can be second supporting arm 12 the balance support is provided.But the end 47 of second spring 24 is not directly connected to the second supporting arm link 18.And as shown in Figure 1, the end 47 of second spring 24 connects sliding connector 32 by one or more connecting groove 42A, 42B, 42C, and the end of sliding connector 32 is connected to the far-end of conjunction 34, and the end of conjunction 34 is pivotally attached to the far-end that articulates chain 36.At last, the end of pivot joint chain 36 is pivotally attached to the second supporting arm link 18 by drive-connecting shaft 44.
It should be noted that in this illustrative examples, articulate chain 36 and first control arm, 28 shared drive-connecting shafts 44.Say that more completely articulating chain 36 can be by given range of pivot, so pivotal axis 39 in pivot, abut to prevention face 40 up to pivot joint chain 36.Slider head 37 is retained on sliding connector 32 on first control arm 28 slidably, separates to stop the two, allows second spring 24 to provide necessary support for second supporting arm 12 simultaneously.The second supporting arm lid, 35 inside are open architecture, accommodate the related elements of first control arm 28 and second control arm 30 and second supporting arm 12.
The end of first supporting arm 14 is articulated on the intermediate connector 16 by drive-connecting shaft 60, and the far-end of first supporting arm 14 is articulated on the upper arm link 20 by drive-connecting shaft 64.Though under a stable condition, it forms two control arms, first supporting arm 14 in the present embodiment has single control arm 52, and its end is articulated on the intermediate connector 16 by drive-connecting shaft 58, and its far-end is articulated on the upper arm link 20 by drive-connecting shaft 62.Drive-connecting shaft 58,60,62,64 effectively forms a parallelogram sturcutre, and then verified upper arm link 20 and be supported the conformity location of thing 22 relative intermediate connectors 16, and because the parallelogram sturcutre of second supporting arm 12, correspond to the second supporting arm link 18 and the supporting surface (not shown) location that also can keep consistency.
It should be noted that provides better when stability if desired, includable with respect to first supporting arm 14 and second control arm 30, removes second control arm 30 and also can from second supporting arm 12.Further say, when second supporting arm 12 and first supporting arm 14 are only arranged, use under the situation of extra supporting arm, can be only with second supporting arm 12.
Can see power, the size and mobile of controlling second supporting arm, 12 balances from Fig. 2 and Fig. 3.Second supporting arm 12 only is simplified as therein to be represented with first control arm 28.Can see that in Fig. 2 the length of second supporting arm 12 from terminal drive-connecting shaft 38 to far-end drive-connecting shaft 49 is L, when the weight that is supported thing 22 is W
SThe time, the weight W of second supporting arm 12
ACan regard the point at position therebetween as, and first supporting arm 14 can be regarded far-end drive-connecting shaft 49 as.Second supporting arm 12 passes through with respect to the angle of pivot α of vertical line in 0 to 90 degree range, and then is pivotally attached to terminal drive-connecting shaft 38.And, weight W
AAnd W
SCan apply moment or be applied to the moment that terminal drive-connecting shaft 38 depends on angle of pivot α.
Referring to Fig. 3, second spring 24 can be regarded as and is hooked on the first connecting groove 42A, like this, when second supporting arm 12 during in the vertical position, can form 0 ° of an original elastic extension Δ, when 24 pairs of sliding connectors 32 of second spring applied elastic force S, angle beta and changed in the rotating range of second supporting arm 12 between the conjunction 34 and first control arm 28.(Zone) I in the area, second spring 24 can effectively be pivotally attached to drive-connecting shaft 44.So, the moment arm of the relative drive-connecting shaft 46 of elastic force S be between drive-connecting shaft 44 and 46 apart from d1.Yet when given pivot joint angle, pivot joint chain 36 can rotate to prevention face 40 and connect, and then stops its further pivot.Like this, when further pivoting, second supporting arm 12 passes area (Zone) II, second spring 24 pivots around the far-end 45 that articulates chain 36, and elastic force S act on the moment arm of the drive-connecting shaft 46 of first control arm 28 be exactly articulate between the far-end 45 of chain 36 and the drive-connecting shaft 46 apart from d2.It should be noted that apart from d2 greater than distance d1.
See also shown in Fig. 4,5,6, be respectively part assembling schematic representation, pin-jointed structure schematic representation of the present invention and another pin-jointed structure schematic representation of the present invention of the present invention's second supporting arm.As shown in the figure: this balance arm 10 is connected to supporting surface 100 (for example desk), make second supporting arm 12 be arranged on the primary importance (POSITION) of vertical position, second supporting arm 12 rotates to the second place of the end of area (Zone) I, second supporting arm 12 pivots, and (Zone) II passes 90 the 3rd positions of spending along the area from vertical line, when primary importance, second spring, 24 initial lengths are SL0, when second supporting arm 12 rotates to the second place, the distance of drive-connecting shaft 44 and second spring, 24 far-ends 43 can increase gradually, cause second spring 24 to extend to the second length SL1 gradually, at this moment, the moment that second spring 24 produces also and then increases gradually, on the second place, second spring 24 is pivotally attached to the far-end 45 that articulates chain 36, not only changed the extension mode that moment arm has also changed second spring 24, the elongation that makes the ratio of elongation of second spring 24 be extended when drive-connecting shaft 44 pivots continuously increases more gradually.
Though single pivot chain link 36 can obtain above-mentioned benefit really, some embodiment of balance arm 10 also can use a plurality of pivot joint chains 36, and then allows the moment of second spring 24 further to be revised.For example, among Fig. 5, conjunction 34 articulates chain 36B and the 3rd by the first pivot joint chain 36A, second and articulates chain 36C to be connected to the second supporting arm link 18, here, the first pivot joint chain 36A, second articulates chain 36B and the 3rd pivot joint chain 36C is the chain chain, can in the given range of pivot of pivotal axis 39, pivot, up to the 40A of the prevention face of abutting to branch, 40B, 40C.More particularly, when second supporting arm 12 leaves the vertical position, can pass first area, second spring 24 can articulate the terminal pivot of chain 36A around first effectively.When given pivoting angle, the first pivot joint chain 36A is pivoted to first and stops face 40A to contact, and second supporting arm 12 enters second area, and second spring 24 articulates the terminal pivot of chain 36B around second.After the second pivot joint chain 36B abutted to the second prevention face 40B, enters the 3rd area, second spring 24 articulated the terminal effectively pivot of chain 36B around second.After the 3rd pivot joint chain 36C abutted to the 3rd prevention face 40C, enters the 4th area, second spring 24 effectively pivoted around the 3rd far-end that articulates chain 36C.Because the diversity of moment arm, the pattern of elastic force S further is adapted to non-linear moment pattern, more can make second supporting arm 12 remain on good state of equilibrium.
Another implements illustrated embodiment to Fig. 6 for the present invention, and articulating chain 36 is spring part, and prevention face 40 is a smooth domatic face, and second spring 24 effectively pivots from the drive-connecting shaft 44 that articulates chain 36 and starts working.Second supporting arm 12 pivots around drive-connecting shaft 38, articulate chain 36 with the vast scale mode gradually with prevention face 40 against, produced the effective drive-connecting shaft that moves continuously, elastic force S can infinitely change, and in order to keep the sinusoidal moment of the needed rising of second supporting arm, 12 balances accurately to conform to.
See also shown in Fig. 7,8 and 9, be respectively the both arms embodiment schematic representation of the rotary state schematic representation of balance arm of the present invention, balance arm of the present invention and the single armed embodiment schematic representation of balance arm of the present invention.As shown in the figure: in analysing and observe among the embodiment of earlier figures 1, the end 51 of first spring 26 is connected to drive-connecting shaft 57 by sliding connector 54 and conjunction 56, though but the drive-connecting shaft 57 that connects first spring, 26 ends can effectively connect intermediate connector 16, is not fixed in the above.And drive-connecting shaft 57 is arranged on the upper arm lid 55 that is pivotally attached to first supporting arm 14, and drive-connecting shaft 57 moves relative to intermediate connector 16, therefore also moves relative to drive-connecting shaft 58, and pivots around drive-connecting shaft 58 relative control arms 52.Just as discussed below, the moment arm of elastic force S changes in the range of movement of first supporting arm 14.And owing to trend towards moving around the far-end 53 of first spring 26, the extension that the ratio of elongation of first spring 26 is fixed on the spring end of arm link reduces to some extent.
The effect of drive-connecting shaft 57 can be explained further combined with Fig. 7.First supporting arm 14 can be expressed as first, second and the 3rd position with simplified way.In the position 1, the moment arm of elastic force S is the perpendicular distance d1 of drive-connecting shaft 57 and drive-connecting shaft 58, but in the position 2, because drive-connecting shaft 57 drives upper arm lid 55 and moves, the moment arm of elastic force S is reduced to the perpendicular distance d2 of drive-connecting shaft 57 and drive-connecting shaft 58, and is last, in the position 3, drive-connecting shaft 57 drives upper arm lid 55 and is moved further, and the moment arm of elastic force S is reduced to the perpendicular distance d3 of drive-connecting shaft 57 and drive-connecting shaft 58.
The moment and the moment arm of first spring 26 are equal proportion, and moment arm is as when d1 is reduced to d3, and the moment of per unit elastic force S also reduces to equal proportion.Mobile trend in conjunction with drive-connecting shaft 57 relative intermediate connectors 16, when the supporting arm relative vertical position pivots in 90 to 180 degree scopes, moment arm reduces gradually, makes the moment of first spring 26 also be reduced to first supporting arm 14 gradually and be supported the moment that thing 22 applies to be corresponding closely at least.When first supporting arm 14 near the position 1 of horizontal position or 90 degree the time, first spring 26 applies enough moment and keeps balance, also avoids first supporting arm 14 at the excessive torque that produced of positions 3 near 180 degree.
See Fig. 1 again, the end 47 of second spring 24 is at any one or more connecting groove 42A, 42B, 42C, or other has on the tie point of transformable length SL0, SL1, SL2 and connects sliding connector 32.Similarly, the end 51 of first spring 26 can be selected what one or more connecting groove 66A in office, 66B, 66C, or other has on the tie point of transformable elastic length SL3, SL4, SL5 and connects sliding connector 54.Balance arm 10 can remain on the equilibrium position validly being supported thing 22.In fact, in given scope, second spring 24 and first spring 26 can be connected with 54 electing property of end sliding connector 32, thus support Different Weight be supported thing 22.For example, the second given spring 24 can be connected on the sliding connector 32 by the first connecting groove 42A, that supports given weight is supported thing 22, similarly, second spring 24 can connect by the second connecting groove 42B or the 3rd connecting groove 42C, and that supports that weight increases gradually is supported thing 22.Manufacturer or assembler can make the balance arm that is supported thing 22 10 that is used for supporting Different Weight especially, and can use minimum different springs.
