First guide rail 21 is fixedly connected, and the display module 10 is fixedly connected on first guide rail 21.Further specifically,
The driving component 30 includes the first motor 31, the second motor 32, first gear 33, second gear 34 and shaft 35.Described
One motor 31 is fixedly connected with the first gear 33.The first guide hole 211 and multiple first are provided on first guide rail 21
Teeth 212.The first gear 33 engages setting with the first teeth 212 on first guide rail 21.First motor 31
The first gear 33 is driven to be moved along first guide hole 211, to drive first guide rail 21 along first curved track
Mark moves, so as to which the display module 10 be driven to be moved along first arching trajectory.The second gear 34 and described second
Motor 32 is fixedly connected.The second guide hole 221 and multiple second teeth 222 are provided on second guide rail 22.Second tooth
Wheel 34 engages setting with the second teeth 222 on second guide rail 22.Second motor 32 drives the second gear 34
It is moved along second guide hole 221, to drive first guide rail 21 and the display module 10 along second arching trajectory
It is mobile.One end of the shaft 35 is rotatablely connected with the first gear 33, and the shaft 35 passes through 211 He of the first guide hole
Second guide hole 221, and the other end of the shaft 35 is rotatablely connected with the second gear 34.It is understood that institute
It states the first motor 31 and second motor 32 works independently of one another.
In the present embodiment, coordinated respectively with the first guide rail 21 and the second guide rail 22 by drive component 30 so that display group
Part 10 is moved along the first arching trajectory and the second arching trajectory, and then changes the space angle of display module 10, so that tiltedly
It can be merged using the image that nearly eye display device right and left eyes are seen depending on user, expand nearly eye display device uses crowd.
In a kind of possible realization method of the application, plane and second curved track where first arching trajectory
Plane where mark is vertically arranged.Specifically, first arching trajectory is the track on horizontal plane.Second arching trajectory
For the track on perpendicular.It is understood that first arching trajectory is overlapped with the center of circle of second arching trajectory,
And the center of circle of the two and the centre of sphere of user eyeball substantially overlap.
The display module 100 is in use, second guide rail 22 is substantially in horizontally disposed.Optionally, described second lead
Rail 22 can be fixed on the fixed frame of nearly eye display device.Second guide hole 221 limits the second gear 34 vertical
