Specific embodiment
The present invention will be further described with specific embodiment with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of location structure of convertible touch display screen, including touch display screen 1 and Analogously, the lower edge of display screen and mounting platform are horizontal for the mounting platform 2 and the prior art of one installation display screen Turning joint with damping is set between upper surface, to make to form rotation connection between display screen and mounting platform.Certainly, I A groove can be set on locating platform, display screen is rotatably connected in groove, in this way, after we can be such that display screen topples over Limit is in groove.
In order to realize the positioning after display screen opening, an accommodating elongated slot can be arranged in the right side edge of display screen in we 11, which extends along the short transverse of display screen, and the long side accommodated on elongated slot close to display screen trailing flank passes through The trailing flank for display screen of holding high office accommodates the side in elongated slot on the upside of display and suspended axle 12 is fixedly installed, hangs on suspended axle There is rotatable support rod 3, positioning head 31 made of ferrimagnet are arranged in one end far from suspended axle on support rod, accordingly Ground, we need to also be located at display screen back location on mounting platform surface and be embedded one piece of phase magnet 4.When beginning, display screen Front sticks on mounting platform surface and is in close state, and support rod at this time, which reclines, accommodates the long side of elongated slot;It needs to make Used time, we can be flipped up and open display screen, when the front that display screen is flipped up opening and display screen is put down with installation When the open angle formed between the upper surface of platform is less than or equal to 90 degree, work of the support rod in elongated slot by self gravity is accommodated With and stick on accommodating elongated slot long side on, support rod at this time rotates synchronously together with display screen.When the front of display screen When the open angle formed between the upper surface of mounting platform is greater than 90 degree, support rod is protected always under the effect of gravity Vertical overhang is held, the center of gravity of support rod is located across in the perpendicular of suspended axle axis, and is accommodated elongated slot and then followed Display is together gradually in tilting backwards state, and the lower end of support rod gradually removes accommodating elongated slot at this time, thus make support rod and Display screen shape is in an angle.When display screen is opened in place, table on the positioning head and mounting platform of the support rod lower end of pendency The phase magnet in face forms magnetic connection, to make support in positioning states, display screen is then in holding state.At this time we When touch display screen, since display screen is supported the supporting role of bar, display screen will not occur shake even continue to After phenomena such as overturning.When we need to overturn to close display screen forward, support rod moves under the drive of display screen, from And the positioning head of support rod lower end and phase magnet are disengaged, the angle between support rod and display screen gradually becomes smaller, until branch Strut reenters positioning in accommodation groove, and display screen is finally made to be in the closed state toppled over.
The positioning of support rod when being in holding state for the ease of display screen, we can make the end spherical surface of positioning head, Correspondingly, the location at spherical surface groove 41 that the setting of phase magnet surface is adapted to the spherical surface of positioning cephalic par.In this way, display screen is in When holding state, snugly detent is in location at spherical surface groove completely for the positioning head of spherical surface, to can ensure that support rod will not go out Existing sliding phenomenon.Certainly, as shown in Figure 3, Figure 4, a mounting groove can be arranged on the surface of mounting platform in we, and phase magnet is embedding It is located in mounting groove, the decorative plastic piece 42 flushed with mounting platform upper surface is then covered on phase magnet, then in plastics Corresponding location at spherical surface groove is arranged in the surface of cosmetic sheet.In this way, can avoid when support rod positioning direct with phase magnet Contact, is conducive to extend service life, while facilitating the processing and manufacturing of phase magnet.
In addition, we can also be rotatablely connected an adjusting rod 5 on support rod, and set between adjusting rod and support rod Position limiting structure is set, to limit rotational angle of the adjusting rod with respect to support rod.Adjusting rod is located on support rod close to display screen front Side, and the free end of adjusting rod is close to suspended axle.In this way, when display screen is flipped up opening greater than 90 degree and in branch When support state, support rod leaves accommodating elongated slot automatically under gravity, and support rod is formed in overhang and with display screen One angle, adjusting rod at this time rotate under the effect of gravity and in an angle with support rod shape, it is acclivitous The upper end of adjusting rod, which reclines, accommodates the long side of elongated slot.Preferably, the angle that adjusting rod and support rod are formed is less than 40 degree.Due to The center of gravity for the component that the support rod that is suspended on suspended axle together and adjusting rod are constituted is located at manufactured center of gravity and adjusting rod Between center of gravity, and the center of gravity of the component should be located across in the perpendicular of suspended axle axis, that is to say, that support rod at this time Center of gravity should be located at the rear side of above-mentioned perpendicular, support rod at this time and generate one by the perpendicular of suspended axle axis Angle is adjusted, to make the angle between support rod and the trailing flank of display screen increased, to be conducive to improve support rod The reliability of positioning of support strength and display screen.When we overturn to close display screen forward, acclivitous adjusting The upper end of bar, which reclines, accommodates the long side sliding of elongated slot, and support rod then moves closer to accommodating elongated slot, to make support rod and adjust Bar is close to each other to be closed up.It is understood that when we change when display screen is in holding state between adjusting rod and support rod When angle, i.e., the position of centre of gravity of the changeable component for having support rod and adjusting rod to be constituted presss from both sides so as to adjust the adjusting of support rod Angle size, and then the open angle of changeable display screen.Certainly, strip can be made in phase magnet by we, and is being positioned It is recessed that multiple location at spherical surface being arranged side by side along the longitudinal direction are set on magnet or in the decorative plastic on piece for covering phase magnet Slot, to make positioning head detent in suitable location at spherical surface groove.
Front side it should be noted that location structure of the invention can be used with the display screen of non-touch, and herein, The directions such as rear side are for display screen, and being located at display screen front side is front side, on the contrary, display screen trailing flank side For rear side.Certainly, an idler wheel 51 can be arranged in the free end of adjusting rod in we.In this way, when display screen be flipped up opening or When person overturns forward closing, the idler wheel of adjusting rod upper end against accommodating elongated slot long side wall, and along the long side wall of accommodating elongated slot It rolls, so as to reduce frictional resistance when adjusting rod is opened, while ensuring that adjusting rod will not when display screen overturns forward closing There is catching phenomenon.
Angle between adjusting rod and support rod when being in holding state for the ease of adjusting display screen, to change at display screen Open angle when holding state, as shown in Figure 5, Figure 6, we can connect setting rotation hole in one end with support rod in adjusting rod 52, position limiting structure includes being embedded the fixture nut 32 coaxial on support rod and with rotation hole, being rotatably arranged in rotation hole Turning set 53, the height of turning set is greater than the thickness of adjusting rod, wears the adjusting being threadedly coupled with fixture nut in turning set Screw 54, fan-shaped regulating tank 521 is arranged on the inner sidewall of rotation hole, and the lateral wall setting of turning set is located at the limit in regulating tank Position protrusion 531.When we, which tighten, adjusts screw, tightening screw in compression turning set makes turning set be snug against fixture nut, from And fix turning set with respect to support rod.Since the height of turning set is greater than the thickness of adjusting rod, adjusting rod, which can surround, to be turned Dynamic set rotation, and retention bead at this time can limit the rotational angle of adjusting rod.Therefore, as long as we, which unclamp, adjusts screw, And turning set is correspondingly rotated, so as to initial position of the retention bead in regulating tank, and tightens adjust screw with fixation again Turning set is convenient to change rotational angle of the adjusting rod with respect to support rod.
Finally, stretching structure can be used in support rod of the invention, by changing the length of support rod, existed with adjusting display screen Open angle when holding state.Specifically, as shown in fig. 7, support rod includes the flat flexible body of rod 33 and and suspended axle The T shape sliding slot axially extended is arranged on the flexible body of rod in the flat fixed core 34 of rotation connection, and fixed link is slidably connected at In the T shape sliding slot of the flexible body of rod, thus the length of adjustable support rod, and adjust the open angle of display screen.Positioning head is set to Far from fixed core one end on the flexible body of rod, the one end being located in T shape sliding slot on fixed core is rotatably connected to circular limit Turntable 6, the periphery of spacing rotating disk are equipped with the short raised line 62 and two phases radially of two diametrically opposed arrangements To the long raised line 61 of arrangement, the angle between short raised line and long raised line is 90 degree.Corresponded on the end face of spacing rotating disk long raised line and A column 63, four columns equidistantly distributed on the circumferencial direction of spacing rotating disk, to make four are respectively set at short raised line A column is gone to upper and lower on spacing rotating disk end face, left and right cross is uniformly distributed.The left side of the flexible body of rod is along its length It is positioned apart from left block 331, middle block 333, lower left block 332, the right side setting for the body of rod that stretches is corresponding with upper left block Upper right block 334, lower right block 335 corresponding with lower left block.In addition, the flexible body of rod is arranged in one end close to suspended axle Blend stop 7 is driven, driving blend stop is corresponding with the column in left side, that is to say, that when spacing rotating disk is moved up close to driving blend stop When, drive the lower end surface of blend stop against the column in left side.
When display screen is flipped up opening and is in holding state, two long raised lines of spacing rotating disk are born against upper On left block and upper right block, to limit the first open angle of display screen, support pole length at this time is the first length, and Two long raised lines are in transversely arranged state, and two short raised lines are in longitudinal arrangement state, two long raised lines and two short raised lines In cross-shaped arrangement.When needing to adjust open angle of the length of support rod to adjust display screen, the specific steps are as follows:
A. user overturns forward display screen, and fixed core drives spacing rotating disk along the body of rod upward sliding that stretches, and stretches The positioning head of contracting body of rod lower end keeps magnetic to connect with phase magnet, as shown in figure 8, vertical on the left of in the column of crossing distribution Column is against the lower end surface of driving blend stop, so that spacing rotating disk be made to rotate counterclockwise 45 degree, originally in the long raised line of cross-shaped arrangement, Short raised line becomes X-shaped arrangement, and the column against driving blend stop is slided and moved along the lower end surface of driving blend stop while rotation Drive the lower end surface of blend stop out, driving blend stop right edge at this time recline script crossing distribution column in left side and upside Two columns, four columns of script crossing distribution then become the square profile of upper left, lower-left, upper right, bottom right, that is, Say, driving blend stop right edge at this time recline square profile column in upper left, the column of lower-left two, to make spacing rotating disk Positioning.It is understood that corresponding position limiting structure can be arranged in we between fixed core and the flexible body of rod, to limit Relative sliding stroke between the two, and then limit the length of support rod.When spacing rotating disk turns over 45 degree, position limiting structure is acted as With fixed core can not keep support rod elongated from the continuous sliding outward of flexible body of rod relaying, and user can experience positioning head and determine The magnetic attraction of position magnet, to stop continuing turning display screen forward;
