Problem to be solved in the utility model is to provide a kind of device of determining angular turn display, canThat in High Density Packaging, realizes display quick determines angular turn.
The technical scheme addressing the above problem: what provide determines angular turn display, comprises display screen,Also comprise runner assembly;
Described runner assembly comprises axle sleeve, rotating shaft and elastic parts;
One end of described rotating shaft is connected with elastic parts, and the other end and display screen are fixed; Described axle sleeve socketIn the outside of rotating shaft; Described elastic parts is arranged between the bottom and rotating shaft of axle sleeve;
The centre of described rotating shaft is provided with limiting tooth, and described axle sleeve inner side is provided with the limit coordinating with limiting toothPosition tooth cover.
Limiting tooth and limiting tooth cover mainly comprise two kinds of structures, specifically: the first is the two ends of limiting toothFor limit limiting tooth, the length of limit limiting tooth is greater than the length of realizing middle limiting tooth, and limiting tooth puts settingThe angular range of tooth cover is less than the angular range that tooth is set on limiting tooth.
The second is that the two ends of limiting tooth cover are limit limiting tooth cover, during the length of limit limiting tooth cover is greater thanBetween the length of limiting tooth cover, limiting tooth puts the angular range that tooth cover is set and is greater than tooth is set on limiting toothAngular range.
Above-mentioned limiting tooth adopts stepped tooth.
The openend of above-mentioned axle sleeve is provided with limiting plate.
Advantage of the present utility model:
What the utility model can be realized in less dimensional space display determines angular turn fast, graspsDo easy, rotate reliability high.

Detailed description of the invention
In conjunction with Figure of description, the utility model is described in detail:
As Fig. 1 determine angular turn display, comprise display screen 1 and runner assembly 2; Runner assembly 2 wrapsDraw together axle sleeve 3, rotating shaft 4 and elastic parts 5; One end of rotating shaft 4 is connected with elastic parts 5, the other end withDisplay screen 1 is fixing; Axle sleeve 3 is socketed in the outside of rotating shaft 4; Elastic parts is arranged at the bottom of axle sleeve 3And between rotating shaft 4; The centre of rotating shaft 4 is provided with limiting tooth 7, and axle sleeve 3 inner sides are provided with and limiting tooth 7The limiting tooth cover 8 coordinating.
Limiting tooth 7 mainly comprises two kinds of structures with limiting tooth cover 8, specifically: the first is limiting tooth 7Two ends be limit limiting tooth 6, the length of limit limiting tooth 6 is greater than the length of realizing middle limiting tooth, limiting toothThe angular range that tooth cover is set on cover 8 is less than the angular range that tooth is set on limiting tooth.
The second is that the two ends of limiting tooth cover are limit limiting tooth cover, during the length of limit limiting tooth cover is greater thanBetween the length of limiting tooth cover, limiting tooth puts the angular range that tooth cover is set and is greater than tooth is set on limiting toothAngular range.
Limiting tooth 7 adopts stepped tooth, and the openend of axle sleeve 3 is provided with limiting plate.
In actual application, front deck display requires to be implemented as follows function: 1, display is collapsibleBe retracted to driving cabin sidewall; 2, display can be adjusted to and pilot's line of vision by driver's actual needsAngle becomes 30 °, 60 ° and 90 °; 3, because of actual installation position dimension spatial limitation, the maximum profile of rotating shaft mechanismSize is not more than 28mm.
For above basic fundamental requirement, design this display and be installed on two cover rotating mechanisms, two coversRotating mechanism is 90 ° of right angles and connects, wherein a set of for practical function 1, another set of installation and the display back of the bodyFace, for practical function 2. Here the rotating mechanism design at the display back side is elaborated, to doExample.
First, according to the maximum appearance and size of mechanism, pre-designed axle sleeve maximum outside diameter D1=27mm, axle sleeve wallThick δ1=2mm, calculates rotating shaft maximum outside diameter D accordingly2< 23mm, default D2＝22mm。
According to the rotational angle requirement to this mechanism in technical requirement, the stepping angle design of known rotating mechanismRequirement is 30 °, calculates accordingly the gauge of limiting tooth: m=0.5* π D2*30/360 ≈ 2.88mm;
Because display device structure does not consider to use lubricator, therefore need be at the limiting tooth 7 of rotating shaft 4 and axle sleeve 3Between reserved certain gap to ensure relative motion smooth and easy of the two, i.e. actual design limiting tooth sizeNeed be less than m, pre-designed rotating shaft limiting tooth Breadth Maximum m2=2.55mm, axle sleeve 3 limiting tooth Breadth MaximumsSize m1＝2.55mm。
Limiting tooth 7 Main Functions are spacing, therefore consider the economy of processing, should adopt stepped tooth. SingleTooth the ratio of width to height approximately gets 2/3; For meeting the functional characteristic of limiting tooth, should increase as much as possible every a pair of limit simultaneouslyThe contact area of position tooth.
To sum up, it is trapezoidal designing spacing profile of tooth, monodentate Breadth Maximum 2.55mm, and minimum widith 1.95mm,Tooth depth 3mm, specifically as shown in Figure 3. In Fig. 3 α angle represent rotating shaft upper limit tooth and rotating shaft intersubjectiveAngle, α=84.3 ° in this example.
After pre-designed, need to adopt the means such as emulation to check design size, can with what ensure structural designLean on property.
It is finally the design to supplementary structure in kinematic pair. In this example, set and display device start angle is 0 °,The maximum anglec of rotation is 90 °, and standing part when design in kinematic pair arranges the limiting tooth that two places are grown,The maximum anglec of rotation to rotating mechanism limits. In kinematic pair, increase axial limiting platform and spring simultaneously,Determine its axial maximum displacement.
