Description

Screen positioning mechanism and display unit in conjunction with multi-form rotating shaft

Technical field

The invention provides a kind of screen positioning mechanism in conjunction with multi-form rotating shaft and display unit, especially a kind of screen positioning mechanism and display unit in conjunction with the rotating shaft of vertical foot rest form and the rotating shaft of photo frame type foot rest form.

Background technique

In the recent period computer with integrated (All in one PC) becomes the market mainstream gradually, but the form of its foot rest is nothing more than continuing to use old display device foot rest specification, and photo frame type foot rest and general vertical foot rest are the most normal foot rest form of employing.Present on the market computer with integrated sales mode is as old LCD Display, the Consumer must determine the foot rest form in advance, and standard replacement hole (Vesa Hold) is not that each manufacturer classifies standard size as, therefore the Consumer is as thinking then difficult of conversion foot rest form (such as photo frame type foot rest, vertical foot rest etc.).See also Fig. 1; Fig. 1 is the structural representation of a vertical foot stand mechanism 10 of prior art; its characteristics are that a screen 12 is fixed on the axle 16 of a base 14; the weight of screen 12 is delivered to the desktop of base 14 and bearing base 14 via axle 16; screen 12 also can rotate in specific angular range around axle 16 in addition; in order to reach laborsaving and the uniform purpose of strength; usually can install the torsion spring assembly additional in axle 16; and because the direction of the moment that screen 12 weight cause is the direction that θ is diminished; so the moment of torsion that the torsion spring assembly provides must be to make θ become large direction; use and offset the moment that screen 12 weight produce, and then reach the labour-saving purpose.

In addition, see also Fig. 2, Fig. 2 is the structural representation of a photo frame type foot stand mechanism 20 of prior art, the leading edge of the screen 22 that photo frame type foot stand mechanism 20 is used for supporting and a support 24 all contact with desktop, therefore former and later two point of contact are arranged, it is adjustable that photo frame type foot stand mechanism 20 also is designed to the rear elevation angle usually, and the mode of adjustment can be divided into two kinds, one for the support 24 that slides on the table by screen 22 lower edges keeps fixing, to reach the purpose of adjusting the rear elevation angle; Another kind then is opposite, be that the point of contact of screen 22 and desktop keeps motionless and support 24 slides on the table, because the weight of screen 22 can make backward slippage of support 24, therefore an axle 26 that connects screen 22 and support 24 need provide enough large friction torque to avoid this phenomenon generation, support can automatic drawing back during the elevation angle after turning down in order conveniently to allow the user, and the user needn't turn back it with an other hand, can install the torsion spring assembly additional in axle 26, because the moment direction that screen 22 weight produce support 24 is to make θ become large direction, so the moment of torsion that the torsion spring assembly provides should be the direction that θ is diminished, use and reduce friction moment and reach the labour-saving purpose.

As from the foregoing, owing to vertical foot stand mechanism and rotating shaft (hinge) mechanical structure of photo frame type foot stand mechanism are opposite principle, that is the moment of torsion that provides of torsion spring assembly when the traditional vertical foot stand mechanism uses and the photo frame type foot stand mechanism when using direction be opposite, and since the restriction of mechanism design at present on the market all without the shared structure of vertical foot rest and photo frame type foot rest, only can be divided into two kinds of independent foot rests, yet vertical foot rest and photo frame type foot rest are respectively had its own the restrictive condition in the use, for example the θ angular region of traditional vertical foot stand mechanism is-5～20 degree, and the θ angular region of traditional photo frame type foot stand mechanism is 20～62 degree, in vertical foot stand mechanism pattern shown in Figure 1, angle of elevation alpha equals θ (alternate interior angle) behind one screen of screen 12, and in photo frame type foot stand mechanism pattern shown in Figure 2 screen 22, support 24, be approximately isosceles triangle with the formed triangle of supporting plane, so the size of angle of elevation alpha approximately is 1/2nd of θ behind the screen.If the rear elevation coverage of the vertical foot rest of specification requirement is-5～20 degree, the rear elevation coverage of photo frame type foot rest is 15～30 degree, the angular range at θ angle is set vertical foot rest be-5～20 degree, and the photo frame type foot rest is that 25～62 degree are acceptable under certain conditions.From the above, therefore multi-form foot rest can be positioned screen the different amount scope, if can vertical foot stand mechanism and photo frame type foot stand mechanism be incorporated into same understructure with breaking through, improving product competitive ability effectively then.

Screen positioning mechanism 56 includes one second rotary axis module 84 in addition, it is connected in one second end 582 of load-bearing member 58, basically the structural similarity of the second rotary axis module 84 and the first rotary axis module 60, in this both differences are made a presentation, structure and the function of all the other same components no longer describe in detail in this.The second rotary axis module 84 includes one second precompressed angle control packing ring 86, which is provided with one second limiting structure, 861, the second limiting structures 861 and can be an arc groove; The second rotary axis module 84 includes one second load component 88 in addition, the second load component 88 can be a torsion spring, one fixed end 881 of the second load component 88 is fixed in the second end 582 of load-bearing member 58, for example can insert the hole on the second end 582, and a movable end 882 of the second load component 88 is arranged in the second limiting structure 861 of the second precompressed angle control packing ring 86.

The opposite direction that arranges owing to the first load component 76 and the second load component 88, therefore both provide the direction of moment of torsion also opposite, in the present invention, can design the first rotary axis module 60 and the second rotary axis module 84 and be respectively the rotary shaft mechanism that vertical foot rest pattern and photo frame type foot rest pattern are suitable for, or design the first rotary axis module 60 and the second rotary axis module 84 and be respectively the rotary shaft mechanism that photo frame type foot rest pattern and vertical foot rest pattern are suitable for.

See also Fig. 8, Fig. 8 is that the first load component 76 under the different conditions, the second load component 88 are controlled the relative position schematic diagram of packing ring 86 in the second limiting structure 861 with the second precompressed angle respectively in the first limiting structure 621 of the first precompressed angle control packing ring 62.For instance, when the angle at the θ angle of 541 on screen 52 and support during between first scope, as under vertical foot rest pattern shown in Figure 3, being essentially-5～20 degree during scope, the first load component 76 all is the end points of precompressed (preload) state and its movable end 762 butts the first limiting structure 621, and screen 52 when in this first scope, rotating because the first load component 76 all is preloading condition, therefore the movable end 762 of the first load component 76 can be connected to the end points of the first limiting structure 621 always, thus by this butt contact, the first load component 76 can provide moment of torsion to the first precompressed angle control packing ring 62 of a first direction and be passed to load-bearing member 58, because the direction in vertical foot rest pattern sub-screen 52 moments that weight causes shown in Figure 3 is the direction that θ is diminished, so the moment of torsion that the first load component 76 provides is to make θ become large direction, use and offset the moment that screen 52 weight produce, and then reaching the labour-saving purpose, this moment, the first rotary axis module 60 was employed rotary shaft mechanism under the vertical foot rest pattern; The same time, when the angle of 55 of screen 52 and supporting planes during between this first scope, one movable end 882 of the second load component 88 slides at the second limiting structure 861 in the mode of the end points of the second limiting structure 861 of not being connected to the second precompressed angle control packing ring 86, that is second load component 88 be in releasing state, this moment the second load component 88 can't provide moment of torsion to load-bearing member 58.

From the above, when the angle of 55 of screen 52 and supporting planes during between this first scope, that is to say and be in vertical foot rest pattern lower time, only there is the first load component 76 of the first rotary axis module 60 can provide moment of torsion to load-bearing member 58, and the second load component 88 of the second rotary axis module 84 is to be in releasing state and can't to provide moment of torsion to load-bearing member 58, therefore can not offset the moment of torsion that the first load component 76 produces.

When the angle at the θ angle of 541 on screen 52 and support when differing from second scope of this first scope, as under photo frame type foot rest pattern shown in Figure 4, being essentially 20～62 degree during scope, the first load component 76 just no longer was in preloading condition and its movable end 762 and slided at the first limiting structure 621 in the mode of the end points of the first limiting structure 621 of not being connected to the first precompressed angle control packing ring 62 this moment, that is first load component 76 be in releasing state, this moment the first load component 76 can't provide moment of torsion to load-bearing member 58; The same time, the second load component 88 all is the end points of the second limiting structure 861 of preloading condition and its movable end 882 butts the second precompressed angle control packing ring 86, and screen 52 when in this second scope, rotating because the second load component 88 all is preloading condition, therefore the movable end 882 of the second load component 88 can be connected to the end points of the second limiting structure 861 always, thus by this butt contact, the second load component 88 can provide in contrast to moment of torsion to the second precompressed angle control packing ring 86 of a second direction of this first direction and be passed to load-bearing member 58, because the direction in photo frame type foot rest pattern sub-screen 52 moments that weight causes shown in Figure 4 is to make θ become large direction, so the moment of torsion that the second load component 88 provides is the direction that θ is diminished, that is to say that support 541 can automatic drawing backs during the elevation angle after turning down in order conveniently to allow the user, and the user needn't turn back it with an other hand, can install the second load component 88 additional, use and offset the moment that screen 52 weight produce.This moment, the second rotary axis module 84 was employed rotary shaft mechanism under the photo frame type foot rest pattern.

From the above, when the angle of 55 of screen 52 and supporting planes during between this second scope, that is to say and be in photo frame type foot rest pattern lower time, only there is the second load component 88 of the second rotary axis module 84 can provide moment of torsion to load-bearing member 58, and the first load component 76 of the first rotary axis module 60 is to be in releasing state and can't to provide moment of torsion to load-bearing member 58, therefore can not offset the moment of torsion that the second load component 88 produces.In addition, this the first scope angle and this second scope angle can overlap or be fully not overlapping, although can weaken the effect of load component under a certain pattern when this first scope angle and this second scope angle part are overlapping for instance, but do not causing the phenomenon of nodding (because of the torsion deficiency, screen is in user's automatic phenomenon of sagging (the rear elevation angle diminishes) when applying external force) and push-pull effort be under the acceptable prerequisite, still be feasible scheme; Or this first scope angle and this second scope angle is fully not overlapping in addition between when not continuing, when support can automatic drawing back if the suffered precompressed angle of load component can provide enough torsion, then still be feasible scheme.

In addition, because screen positioning mechanism 56 of the present invention has two kinds of usage mode of vertical foot rest pattern and photo frame type foot rest pattern, and different usage mode is also not identical to the demand of friction torque, take the first rotary axis module 60 as example, it can reach the purpose of adjusting friction torque by the structural design of the first friction torque control packing ring 70 and the second friction torque control packing ring 72.When screen 52 as shown in Figure 3 when being in vertical foot rest pattern, the first protuberance 701 of the first friction torque control packing ring 70 is contacted with the second protuberance 721 of the second friction torque control packing ring 72, the first friction torque control this moment packing ring 70 is larger with the forward frictional force of 72 on the second friction torque control packing ring, and integral body just can provide larger friction torque under vertical foot rest pattern thus; And when screen 52 as shown in Figure 4 when being in photo frame type foot rest pattern, the first protuberance 701 of the first friction torque control packing ring 70 can't be contacted with the second protuberance 721 of the second friction torque control packing ring 72, the first friction torque control this moment packing ring 70 is less with the forward frictional force that the second friction torque is controlled 72 on packing ring, therefore integral body just can provide less friction torque under photo frame type foot rest pattern, larger friction torque need be provided and the actual demand of less friction torque need be provided in photo frame type foot rest pattern lower rotary shaft module and meet in vertical foot rest pattern lower rotary shaft module, as for the large I of friction torque by the THICKNESS CONTROL of space washer 74 it.

From the above, screen positioning mechanism 56 of the present invention has been integrated the rotary shaft mechanism design of two kinds of different sizes, that is first rotary axis module 60 and the second rotary axis module 84 be respectively the rotary shaft mechanism that vertical foot rest pattern and photo frame type foot rest pattern are suitable for, the rotary shaft mechanism that this point is different from the base left and right sides of prior art is the design of identical torsion spring.In addition, the present invention may produce the problem of cancelling each other in order to solve two torsion spring moment opposite directions, so design is when using vertical foot rest pattern, the first rotary axis module 60 that is applicable to vertical foot rest pattern can do to provide moment of torsion to screen 52, and it is ineffective and can't provide moment of torsion to screen 52 to be applicable to the second rotary axis module 84 of photo frame type foot rest pattern this moment; Otherwise, when using photo frame type foot rest pattern, the second rotary axis module 84 that is applicable to photo frame type foot rest pattern can do to provide moment of torsion to screen 52, and it is ineffective and can't provide moment of torsion to screen 52 to be applicable to the first rotary axis module 60 of vertical foot rest pattern this moment.

Moreover, the present invention utilizes the fixed end 881 of the fixed end 761 of the first load component 76 and the second load component 88 to be individually fixed in first end 581 and second end 582 of load-bearing member 581, and the movable end 882 of the movable end 762 of the first load component 76 and the second load component 88 slidably is arranged at respectively the first limiting structure 621 of the first precompressed angle control packing ring 62 and the structural design that the second limiting structure 861 of packing ring 86 is controlled at the second precompressed angle, reach a kind of and provide the function of screen location with only activating a kind of rotary axis module under the pattern, that is first load component 76 and the second load component 88 need to be designed to an end be that fixed end and the other end are movable end, therefore the present invention also can design first end 581 and the second end 582 that the first limiting structure 621 and the second limiting structure 861 is formed at respectively load-bearing member 581, therefore the fixed end 881 of the fixed end 761 of the first load component 76 and the second load component 88 is individually fixed in the first precompressed angle control packing ring 62 and the second precompressed angle control packing ring 86, and the movable end 762 of the first load component 76 and the movable end 882 of the second load component 88 slidably are arranged at respectively in second limiting structure 861 of the first limiting structure 621 and the second end 582 of load-bearing member 581 of first end 581 of load-bearing member 581, its action principle also is same as above-described embodiment, just repeats no more in this.

Be compared to prior art, screen positioning mechanism provided by the present invention and display unit combine the rotating shaft of vertical foot rest form and the rotating shaft of photo frame type foot rest form simultaneously, therefore can provide the two kind different use patterns of vertical foot rest pattern from photo frame type foot rest pattern in same display unit, not only can increase thus the scope of screen orientation angle, also can provide the user various foot rest formal argument, therefore be a niche type product specification.

The above only is preferred embodiment of the present invention, and every equivalent variations that claims scope is done according to the present invention and modification all should belong to the covering scope of patent of the present invention.
