Description
Technical field
The present invention relates to display device structure technical field, refer in particular to a kind of display and computing machine.
Background technology
At present, for meeting user's different user demands, all types of displays all possess has highly adjusting and angle of inclination to regulate two kinds of regulatory functions, especially for touch-type display, free adjustment display flexibly, make operator can be adjusted to arbitrarily the convenient position touching, and can both realize touch request for utilization in adjustable extent, the consideration emphasis designing for display device structure.
Yet, the display of prior art, conventionally highly adjusting and angle of inclination adjusting are all independently carried out, the adjustment process of display need to make two bites at a cherry, first adjust up and down the anglec of rotation highly again, or the first anglec of rotation carries out highly regulating up and down again, and operating process is loaded down with trivial details, for using, make troubles.
In addition, in prior art, the adjusting at angle of inclination relies on rotating shaft to complete, but in order to make display in the process regulating, the problem because of the center of gravity of display does not cause toppling over of display, often the arrangement for adjusting height of display is designed to tube-in-tube structure (carrying out adjusting straight up and down by the mode of pull), also needs to guarantee that the display screen place face of display is not parallel with base place face simultaneously.So not only make user's inconvenience that operates, also limited the use pattern of display simultaneously.For example, with touch-type display, just only can guarantee the display screen place face use pattern substantially vertical with base place face of display.The use pattern that the display screen place face of display is substantially parallel with base place face cannot realize, thereby limited the development of touch-type display, because limited the advantage touching under the display screen place of the display face use pattern substantially vertical with base place face, for example, user can only touch hand is unsettled on vertical screen, easily cause the fatigue of hand, also cannot carry out in addition many people and touch interaction etc. simultaneously.

In addition, the rotational angle of display device 1 is different from the rotational angle of bracing frame 2, and both differ 90 degree, can guarantee to realize above-mentioned whole motion process while gear train being set between the two.
Therefore, by described gear train, make described display device with respect to the rotation of support frame as described above, drive support frame as described above to rotate with respect to described base, the center of gravity that guarantees described display is positioned at the predetermined space consisting of described presumptive area, be that display rotates in adjustment process, center of gravity can not depart from the vertical support scope of base, thereby can not cause display run-off the straight yet.
To the structure of display described in the specific embodiment of the invention be described in detail below.
Fig. 4 is for for illustrating the decomposing schematic representation of display device structure principle described in first embodiment of the invention.Consult Fig. 4, described in the first embodiment, display 100, except comprising display device 110, bracing frame 120, base 130, the first rotating shaft 111 and the second rotating shaft 131, also comprise gear train, be used for making between display device 120 and bracing frame 120 simultaneously in relative rotation, bracing frame 120 also can rotate with respect to base 130, can make display 100 turn to the third state shown in Fig. 3.
In first embodiment of the invention, as Fig. 4, described gear train comprises drive link 140, the second rotating shaft 112 and the 4th rotating shaft 132.
Below the structure to first embodiment of the invention is described in detail.
Display device 110, comprises display screen etc., and for showing image, the shape of this display device 110 and structure are not the emphasis of technical solution of the present invention, at this, do not specifically describe; Diverse location in described display device 110 is provided with the first rotating shaft 111 and the 3rd rotating shaft 112, in the specific embodiment of the invention, the first rotating shaft 111 and the 3rd rotating shaft 112 are positioned in a prodger 113 of display device 110, and the first rotating shaft 111 and the 3rd rotating shaft 112 disalignments.
Bracing frame 120, for supporting display device 110, comprises first end and the second end, and wherein first end is provided with axle sleeve 121, the second ends and is provided with axle sleeve 132.
Base 130 for the firm display device 110 of placing, is provided with out-of-alignment the second rotating shaft 131 and the 4th rotating shaft 132 on base 130.
Drive link 140, comprises first end and the second end, and wherein first end is provided with axle sleeve 141, the second ends and is provided with axle sleeve 142.
When described in the first embodiment, display 100 combinations are installed, the axle sleeve 121 of bracing frame 120 first ends is sheathed in the first rotating shaft 111, and the axle sleeve 122 of bracing frame 120 second ends is sheathed in the second rotating shaft 131 of base 130.By the first rotating shaft 111, bracing frame 120 can be rotated with respect to display device 110; By the second rotating shaft 131, bracing frame 120 can be rotated with respect to base 130.Because bracing frame 120 has for supporting the effect of display device 110, when display 100 is placed with state shown in Fig. 2, friction force between bracing frame 120 and the first rotating shaft 111 needs to guarantee that display device 110 can fix with angle of inclination shown in Fig. 2, and between bracing frame 120 and the second rotating shaft 131, friction force needs to guarantee that bracing frame 120 fixes with angle of inclination shown in Fig. 2, therefore when display device 110 is rotated with respect to bracing frame 120, or when bracing frame 120 is rotated with respect to base 130, all need to apply certain rotating force.
