Abstract

A wearable device includes a load-carrying device and an optomechanical device detachably mounted at a side of the load-carrying device. The optomechanical device includes a display screen configured to display an image and an optical assembly configured to project the image.

Claims

1. A wearable device comprising:

a load-carrying device; and

an optomechanical device detachably mounted at a side of the load-carrying device, the optomechanical device including;

a display screen configured to display an image; and

an optical assembly configured to project the image.

2. The device of claim 1, wherein:

the load-carrying device includes a middle housing; and

the optomechanical device further includes a side housing detachably mounted at the middle housing.

3. The device of claim 2, wherein:

the load-carrying device further includes a processing apparatus arranged inside the middle housing and configured to process data and control an operation of the wearable device.

4. The device of claim 2, wherein:

the middle housing includes two side surfaces, the two side surfaces being located at two sides of the middle housing; and

the side housing is mounted at one of the two side surfaces.

5. The device of claim 4, wherein an angle between the two side surfaces is an acute angle.

6. The device of claim 4, wherein:

the load-carrying device further includes a first connector arranged at one of the two side surfaces;

the side housing includes a connecting surface connected to the middle housing;

the optomechanical device further includes a second connector arranged at the connecting surface and corresponding to the first connector; and

the first connectors is connected to the second connector to detachably mount the side housing to the middle housing.

7. The device of claim 6, wherein:

the load-carrying device further includes a power supply apparatus arranged inside the middle housing; and

the power supply apparatus is configured to provide power to the optomechanical device via the first connector and the second connector.

8. The device of claim 7, wherein the power supply apparatus includes a rechargeable battery.

9. The device of claim 7, wherein:

the middle housing further includes a receiving slot; and

the power supply apparatus is arranged inside the receiving slot.

10. The device of claim 4, further comprising:

a headband including a first buckle;

wherein;

the middle housing further includes a front surface connected between the two side surfaces;

a second buckle is arranged at the front surface; and

the middle housing is detachably mounted at the headband through the first buckle and the second buckle.

11. The device of claim 2, further comprising:

a headband;

wherein;

the middle housing is fixed to the headband via screw connection, snap fit, or a combination of screw connection and snap fit;

or

the middle housing and the headband are integrally formed as one piece.

12. The device of claim 2, wherein:

the optomechanical device further includes an optomechanical housing arranged inside the side housing and including;

a first mounting surface;

a second mounting surface connected to the first mounting surface, the display screen being arranged at the second mounting surface; and

a third mounting surface obliquely connected to the first mounting surface and the second mounting surface; and

the optical assembly includes;

an eyepiece arranged at the first mounting surface; and

a reflective component arranged at the third mounting surface and configured to reflect the image toward the eyepiece.

13. The device of claim 12, wherein:

an angle between the reflective component and the first mounting surface is an acute angle; and

an angle between the reflective component and the second mounting surface is an acute angle.

14. The device of claim 12, wherein the display screen includes a Liquid Crystal Display (LCD) display or an Organic Light-Emitting Diode (OLED) display.

15. The device of claim 2, wherein:

the optomechanical device further includes an optomechanical housing arranged inside the side housing and including;

a first mounting surface;

a second mounting surface connected to the first mounting surface, the display screen being arranged at the second mounting surface; and

a third mounting surface obliquely connected to the first mounting surface; and

the optical assembly includes;

an eyepiece arranged at the first mounting surface; and

a semi-transparent component arranged between the second mounting surface and the third mounting surface and configured to reflect the image toward the eyepiece.

16. The device of claim 15, wherein:

the optomechanical housing further includes a fourth mounting surface opposite to the first mounting surface and connected between the second mounting surface and the third mounting surface; and

the optical assembly further includes a light-adjustable component arranged at the fourth mounting surface and opposite to the semi-transparent component, the light-adjustable component having an adjustable light transmittance and being configured to project light passing through the light-adjustable component toward the semi-transparent component.
