Description
Technical field
The invention belongs to the support technology field of the display devices such as flat panel TV, flat panel display and computer all-in-one machine, specifically, the present invention relates to one and look squarely, look up rapid translating support.
Background technique
Market is not seen can take into account sitting posture and lying posture and conversion fast, the display device support that Applicable scope is larger.
At present, there is the wall mounting type television rack of lifting function, as the patent No. is: 201120480832.X, title is the utility model patent of " slide track type display screen lift device ", it is by the form of gear and tooth bar, controls display screen lifting, its complicated mechanism, gear rack precision prescribed is high, processing difficulties, cost is high, and rising or falling speed is slow, and only can realize lifting function, the angle of display screen can not be rotated.
The patent No. is 201220086366.1, and title is the utility model patent of " lifting television frame ", and it has above-mentioned shortcoming too.
The patent No. is 201110211829.2, and title is the patent of invention of " a kind of TV hanger of angle adjustable ", and it is coordinated by adjustment pin and screens in keyway, and realize the angle adjustment of flat panel TV, it does not possess lifting function; In addition, its angle adjustment mechanism also more complicated.During adjusting angle, need to pull stay cord, carry out regulating and controlling pin turnover draw-in groove by the motion of skewback; It has following shortcoming: 1, the size of skewback and TV angle of inclination are directly proportional; The angle that the larger TV of skewback can tilt is larger.But because TV needs to arrange by wall, and skewback certainly will cause very greatly TV distance wall far away.That is, TV angle of inclination and the distance between TV to wall are directly proportional; This just causes the raising required TV usage space, bad adaptability.
The patent No. is 200710125684.8, and title is " electric remote control wall hanging rack of flat television ", and it controls flat panel TV by remote-control motor and rotates; Still there is the problem that TV cannot lean on wall very near in it, bad adaptability.
The patent No. is: in two patents of 201220277422.X and 201010225570.2, is all the elevator mechanisms for computer monitor and notebook computer; Although it also uses quadratic crank mechanism and air spring, it only plays lift action; Only can finely tune among a small circle, can not reach the object of significantly synchronous change angle, therefore, also cannot realizing lies on a bed sees the object of TV.
In addition, the technological scheme recorded in above-mentioned all kinds of patents, all cannot make television set change angle and extending forwards in lifting simultaneously.And can not meet lies flat on the bed cosily sees the requirement of TV.
Also have some to have the suspended ceiling TV frame of lifting function, if the patent No. is the utility model patent of 03258270.6, it, by the different positioning hole on suspension rod, realizes the lifting of TV, and it is elevated trouble, needs manpower to promote, uses inconvenience.Because of its structure problem, display device rotation angle is also very limited, and for the people lied on a bed, rotation angle is negligible.
Also have some suspended ceiling TV frame, though meet the requirement of looking up, can not meet the requirement of looking squarely, cannot drop to enough low, cannot be close to metope again, take up room large, viewing distance is pulled open in inconvenience again.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of structure simple, can realize fast lifting, simultaneously can also the looking squarely of synchronous change display device angle, look up rapid translating support.
For reaching above-mentioned purpose of the present invention, the present invention adopts following technological scheme, the present invention includes the quadratic crank mechanism be hinged successively by frame seat, upper rocker arm, link arm bar and lower shake-changing arm head and the tail, it is characterized in that: also comprise flexible rod, described flexible rod one end is hinged with frame seat, and the other end of flexible rod is hinged with upper rocker arm or lower shake-changing arm.
As a preferred embodiment of the present invention, described flexible rod is air spring or electric pushrod.
Further, described air spring arranges latching point in rotation path.
Further, described air spring by displacement buffer and frame seat slide hinged.
As another kind of preferred version of the present invention, described lower shake-changing arm by rocking arm length compensation device and frame seat slide hinged.
Beneficial effect of the present invention: 1, the present invention promotes quadratic crank mechanism with frame seat by flexible rod is that fixed edge rotates, and while rotation, the angle of link arm bar also can change thereupon; When link arm bar is positioned at bottom, link arm bar is vertically, and when link arm bar is positioned at topmost, link arm bar is tilted to down; Be installed on by display device on link arm bar, what can realize looking squarely and look up have switched fast, and structure is simple, and display device is near with wall distance when looking squarely, and production and processing facilitates, low production cost; In addition, motion mode of the present invention is simple, fast.
2, flexible rod of the present invention is set to air spring, by the thrust of air spring, is convenient to the lifting controlling display device, quick, laborsaving.Further, air spring arranges latching point, and when display device rises, air spring unlocks through latching point, is upwards pushed away by quadratic crank mechanism, and display device is peaked.When display device declines, air spring locks through latching point, and make display device remain on minimum point, it is active in one's movements, and conversion settles at one go, without the need to finely tuning and specially locking.
3, flexible rod of the present invention uses electric pushrod, is convenient to the control to display device lifting heights, can rests on arbitrary height arbitrarily; And the object of remote pilot can be reached, easy to use.
4, air spring of the present invention is slide hinged with the displacement buffer on frame seat, air spring can be helped to increase bearing diagonal power, and can increase the effective travel of air spring.
5, lower shake-changing arm of the present invention is slide hinged with the rocking arm length compensation device on frame seat; By rocking arm length compensation device, can integrating error be compensated, can ensure that display device is when minimum point and metope keeping parallelism.
6, due to structural feature of the present invention, lifting distance of the present invention is large, can reach more than 1 meter.
