Limitation.
Below with reference to Fig. 1 to Figure 12 description according to the rotating mechanism for display terminal 200 of the utility model embodiment
100。
As shown in Figure 1, according to the rotating mechanism 100 for display terminal 200 of the utility model first aspect embodiment
It include: installation unit 10, driving motor 20 and gear drive 30.
Specifically, installation unit 10 is for installing display terminal 200, such as it can be vehicle-mounted flat or installed video
Display screen, display terminal 200 can be connected with installation unit 10 by screw, also can use sucker and adsorb installation unit 10
At the back side of display terminal 200.Driving motor 20 can be common direct current generator, be equipped with motor shaft in motor, motor shaft
Central axis can be parallel to the back side of display terminal 200.
Wherein, gear drive 30 include: driven gear 31 and with driven gear 31 intermeshing first actively
Gear 32 and the second driving gear 33, driven gear 31 are connected on installation unit 10, and the first driving gear 32 is connected to driven
Between gear 31 and motor shaft, the second driving gear 33 is also connected between motor shaft and driven gear 31.Gear drive
30 be configured to can rotation by the translating rotation of motor shaft at installation unit 10, that is to say, that motor shaft rotation drives first
Driving gear 32 rotates, and the first driving gear 32 drives driven gear 31 to rotate, and then drives installation unit 10 and display terminal
200 rotations, similarly, motor shaft rotation drive the rotation of the second driving gear 33, and the second driving gear 33 drives driven gear 31
Rotation, and then installation unit 10 and display terminal 200 is driven to rotate.
As a result, according to the rotating mechanism 100 of the display terminal of the utility model embodiment 200, by installation unit 10 with
Display terminal 200 is fixedly connected so that display terminal 200 to be fixed on car body, and actively using the first driving gear 32, second
Gear 33 and driven gear 31 cooperate, and drive display terminal 200 to rotate under the driving effect of driving motor 20.Thus not only may be used
It is rotated freely with realizing display terminal 200 vehicle is intracorporal, and the first driving gear 32 is set and the second driving gear 33 can
To increase the rotational stabilization of driven gear 31, and then promote the stability of display terminal 200.
The rotating mechanism 100 of one embodiment according to the present utility model, gear drive 30 are configured at least drive
Dynamic display terminal 200 switches between transverse screen and vertical screen.
Specifically, driving motor 20 it is electric after rotate, to drive the first driving gear 32 being attached thereto and second main
Moving gear 33 rotates, and then driven gear 31 is driven to rotate, and display terminal 200 and installation unit 10 are with driven gear 31
Rotation and move, and then driving motor 20 can the power down under the operation of operator, that is to say, that operator can be according to itself
Requirement, switch display terminal 200 at least between transverse screen and vertical screen, so that operator can be in the position of the most comfortable
On watched, to improve viewing experience.
As shown in Fig. 2, one embodiment according to the present utility model, gear drive 30 further include: worm screw 34, worm screw
34 are connected with motor shaft and are formed with helical tooth in the axially extending of motor shaft, worm screw 34, and worm screw 34 connects the first driving tooth
