Abstract

Embodiments of the present disclosure provide a wearable projection equipment, comprising a first structure body and a second structure body which are movably connected to each other, and the first structure body can rotate relative to the second structure body; and a projection device is respectively provided on the first structure and the second structure. The wearable projection equipment is capable of projecting images in different directions respectively, such that application scenarios of the wearable projection equipment become more extensive.

First claim

The invention claimed is:

1. A wearable projection equipment, comprising:
a first structure body and a second structure body which are movably connected to each other and are configured to be rotatable relative to each other, the first structure body being a first ring-shaped body, and the second structure body being a second ring-shaped body;
an end opening of the first ring-shaped body and an end opening of the second ring-shaped body connected to each other in a telescope manner;
tooth-shaped structures meshing with each other are respectively provided at the two end openings where the first ring-shaped body and the second ring-shaped body connected to each other;
wherein a projection device is respectively provided on the first structure body and the second structure body; and
wherein an electrode is provided at a tooth tip of the tooth-shaped structure of the first ring-shaped body, and an electrode is provided at a tooth root of the tooth-shaped structure of the second ring-shaped body.

2. The wearable projection equipment of claim 1 , wherein the wearable projection equipment is a projection ring.

3. The wearable projection equipment of claim 1 , wherein
the electrode provided at the tooth tip of the tooth-shaped structure of the first ring-shaped body and the electrode provided at the tooth root of the tooth-shaped structure of the second ring-shaped body are electrically connected to each other, where the tooth-shaped structure of the first ring-shaped body and the tooth-shaped structure of the second ring-shaped body meshing with each other.

4. The wearable projection equipment of claim 1 , further comprising a touch detection module which is configured to detect a touch action of a finger or a touch pen on an object as a projection screen.

5. The wearable projection equipment of claim 4 , wherein the touch detection module comprises a laser generator and a laser detector, wherein the laser generator is configured to generate a laser projected on a surface of the object as the projection screen, and the laser forms a spot on the finger or the touch pen, and the laser detector detects a mapping position on the keyboard pattern corresponding to the spot on the finger or the touch pen upon a finger or a touch pen performs a pressing-key operation on the surface of the object as the projection screen having a keyboard pattern.

6. The wearable projection equipment of claim 4 , wherein the touch detection module is provided on at least one of the first structure and the second structure.

7. The wearable projection equipment of claim 4 , wherein the touch detection module comprises a laser generator and a laser detector, wherein the laser generator is configured to generate a laser projected on a surface of the object as the projection screen, and the laser detector is configured to determine a touch position of a finger or a touch pen through a spot formed by the laser on the finger or the touch pen performing an operation on the projection screen.

8. The wearable projection equipment of claim 1 , further comprising:
a wireless module which is electrically connected to the projection devices on the first ring-shaped body and the second ring-shaped body respectively, and is used to achieve the communication and/or electrical connection between the projection device and other equipments.

9. The wearable projection equipment of claim 2 , further comprising a touch detection module which is configured to detect a touch action of a finger or a touch pen on an object as a projection screen.
