Abstract

This disclosure relates to a display module assembly that includes two optical module assemblies, two first adjustment mechanisms, two image generation devices, and two second adjustment mechanisms each corresponding to one of the first adjustment mechanisms. Each first adjustment mechanism is movably connected to a corresponding one of the optical module assemblies for adjusting distance between the two optical module assemblies. Each image generation device is movably connected to a corresponding one of the optical module assemblies, and project an image to a predetermined direction through its corresponding optical module assembly. Each second adjustment mechanism is movably connected to corresponding one of the image generation devices for adjusting a distance between the image generation device and the optical module assembly. The display module assembly and an electronic device in this disclosure can adjust an interpupillary distance and a diopter so as to adapt for different users.

First claim

What is claimed is:

1. A display module assembly, comprising:
two optical module assemblies;
two first adjustment mechanisms, each of the two first adjustment mechanisms connected to a corresponding one of the two optical module assemblies, wherein the two first adjustment mechanisms are configured to adjust a distance between the two optical module assemblies;
two image generation devices, each of the two image generation devices movably connected to a corresponding one of the two optical module assemblies, wherein an image generated by each of the two image generation devices is configured to be projected in a predefined direction by a corresponding one of the two optical module assemblies; and
two second adjustment mechanisms, each of the two second adjustment mechanisms corresponding to a respective one of the two first adjustment mechanisms and connected to a corresponding one of the two image generation devices, wherein each of the two second adjustment mechanisms is configured to adjust a distance between one of the two image generation devices and a corresponding one of the two optical module assemblies,
wherein each of the two first adjustment mechanisms further comprises a base and a first moving element that is movably connected to the base, and a corresponding one of the two optical module assemblies is configured to move with the first moving element,
wherein each of the two second adjustment mechanisms further comprises a second operating element and a second moving element movably connected to the second operating element, the second operating element is movably engaged with the first moving element and at least one portion of the second operating element and a corresponding optical module assembly are located higher than the base, and the second operating element is configured to drive the second moving element to move a corresponding image generation device.

2. The display module assembly as recited in claim 1 , wherein the base further comprises a base plate and a first guiding part located on the base plate for defining a first direction, and the first guiding part is coupled to the first moving element for limiting a movement of the first moving element along the first direction.

3. The display module assembly as recited in claim 2 , wherein the base further comprises a first position-limiting part, and the first moving element further comprises a second position-limiting part, the first position-limiting part works in concert with the second position-limiting part for preventing the first moving element from disengaging the base in a direction substantially perpendicular to the first direction.

4. The display module assembly as recited in claim 3 , wherein the second position-limiting part extends outwards from two opposite sides of the first moving element, the first guiding part further comprises two edges respectively extending upwards from two opposite sides of the base plate, the first position-limiting part is positioned at the two edges, and the second position-limiting part is located between the first position-limiting part and the base plate.

5. The display module assembly as recited in claim 1 , wherein the first adjustment mechanism further comprises a positioning module assembly connected to the first moving element, and the positioning module assembly works in concert with the base for fixing the first moving element at a predefined location after the optical module assembly is moved to the predefined location by the first adjustment mechanism.

6. The display module assembly as recited in claim 5 , wherein the base further comprises a first engagement part, the positioning module assembly further comprises a connection element and an elastic element, and the connection element further comprises a hosting part connected to the elastic element and a second engagement part, the first engagement part and the second engagement part are coupled to each other by the elastic element for positioning.

7. The display module assembly as recited in claim 6 , wherein the elastic element pushes the connection element to force the first engagement part and the second engagement part to be coupled together in response to an external force decoupling first engagement part from the second engagement part.

8. The display module assembly as recited in claim 6 , wherein the first adjustment mechanism further comprises a first operating element connected to the connection element, at least one portion of the first operating element and a corresponding optical module assembly are located higher than the base, and an act on the first operating element causes deformation at the elastic element.

9. The display module assembly as recited in claim 8 , wherein the first operating element further comprises a covering element fixed to the first moving element, and the positioning module assembly and the second operating element are both located between the first operating element and the covering element.

10. The display module assembly as recited in claim 9 , wherein the second operating element further comprises a roller and a rolling shaft supported by the first moving element such that the roller rotates around an axis of the rolling shaft, the roller further comprises a spiral-shape accommodating hole extending from the rolling shaft to an outer edge of the roller, and the second moving element further comprises a slide bar passing through the accommodating hole and spirally sliding through the accommodating hole.

11. The display module assembly as recited in claim 10 , wherein the covering element further comprises a second guiding part, the second moving element is movably confined by the covering element for moving along a direction defined by the second guiding part.

12. The display module assembly as recited in claim 6 , wherein the connection element further comprises a supporting part rotatably located on the first moving element such that the connection element can rotate around the supporting part, the supporting part and the hosting part are positioned at two opposite ends of the connection element, and the second operating element is rotatably located on the supporting part.

13. The display module assembly as recited in claim 1 , wherein the first adjustment mechanism further comprises a first operating element, the first operating element further comprising a covering element fixed to the first moving element, the second operating element is rotatably confined between the first operating element and the covering element, and the second moving element is movably confined by the covering element.

14. The display module assembly as recited in claim 13 , wherein the second operating element comprises a roller and a rolling shaft, the rolling shaft being rotatably confined between the first operating element and the covering element such that the roller rotates around an axis of the rolling shaft, the roller further comprises a spiral-shape accommodating hole extending from the rolling shaft to an outer edge of the roller, and the second moving element further comprises a slide bar passing through the accommodating hole and spirally sliding through the accommodating hole.

15. An electronic device, comprising a housing and a display module assembly as recited in claim 1 , wherein the display module assembly is located within the housing, and at least one portion of the two first adjustment mechanisms and the two second adjustment mechanisms extends outside the housing.
