Abstract

It is provided according to embodiments of the application a connecting device and an electronic device including the connecting device. The connecting device includes a first mounting plate, a second mounting plate, a hinge assembly and a filler. The hinge assembly rotatably connects the first mounting plate and the second mounting plate, and the filler fills a gap inside the hinge assembly.

First claim

What is claimed is:

1. An enveloping mechanism fixed to a body of an electronic device and enveloping at least a portion of a connecting device, the enveloping mechanism comprises at least one bendable and stretchable device, the bendable and stretchable device comprises:
a first connecting body with a first tightness;
a second connecting body with a second tightness;
the first connecting body and the second connecting body are connected to each other, and in a case that the connecting device rotates by various angles, the first connecting body and the second connecting body cooperatively bend without appearing a crease or a fold.

2. The enveloping mechanism according to claim 1 , wherein the first tightness is smaller than the second tightness, and the first connecting body is easier to be stretched than the second connecting body.

3. The enveloping mechanism according to claim 2 , wherein the second connecting body is made of a non-stretchable material.

4. The enveloping mechanism according to claim 1 , wherein the first connecting body and the second connecting body are connected to each other in series.

5. An electronic device comprising:
a first body;
a second body;
a connecting device configured to connect the first body and the second body; and
a first enveloping mechanism enveloping and shielding at least a portion of the connecting device, and the first enveloping mechanism comprising at least one bendable and stretchable device, each bendable and stretchable device comprises a first connecting body with a first tightness and a second connecting body with a second tightness, the first connecting body and the second connecting body are connected to each other, and in a case that the connecting device rotates by various angles, the first connecting body and the second connecting body cooperatively bend without appearing a crease or a fold.

6. The electronic device according to claim 5 , wherein the first tightness is smaller than the second tightness, and the first connecting body is easier to be stretched than the second connecting body.

7. The electronic device according to claim 6 , wherein the second connecting body is made of a non-stretchable material.

8. The electronic device according to claim 5 , wherein the first enveloping mechanism is fixed respectively to the first body and the second body.

9. The electronic device according to claim 5 , wherein the connecting device comprises:
a first mounting plate;
a second mounting plate;
a hinge assembly rotatably connecting the first mounting plate and the second mounting plate; and
a filler filling a gap inside the hinge assembly.

10. The electronic device according to claim 9 , wherein the hinge assembly comprises at least two multispindle hinges, and the filler fills a gap between the at least two multispindle hinges.

11. The electronic device according to claim 10 , wherein the filler is an arc-shaped structure, and an arc-shaped side wall of the arc-shaped structure is provided with at least one through hole passing though the arc-shaped side wall along an extending direction of the arc-shaped side wall.

12. The electronic device according to claim 11 , wherein the multispindle hinge comprises a plurality of spindles parallel to each other, adjacent spindles are connected to each other via a connector, and a spindle located at the edge of the multispindle hinges is provided with a connecting rod, wherein the connecting rods at a first side of the multispindle hinges are fixedly connected to the first mounting plate, and the connecting rods at a second side of the multispindle hinges are fixedly connected to the second mounting plate, and the number of the spindles in the multispindle hinge is the same as the number of the through holes in the filler.

13. The electronic device according to claim 12 , further comprising a second enveloping mechanism, wherein the first enveloping mechanism envelops at least partial areas of the hinge assembly and the filler, and the second enveloping mechanism is located between adjacent fillers and enveloping the connector.

14. A connecting device, configured to connect a first body of an electronic device and a second body of the electronic device, the connecting device comprising:
a first mounting plate;
a second mounting plate;
a hinge assembly rotatably connecting the first mounting plate and the second mounting plate;
a filler filling a gap inside the hinge assembly; and
a first enveloping mechanism enveloping at least partial areas of the hinge assembly and the filler, the first enveloping mechanism comprising at least one bendable and stretchable device, each bendable and stretchable device comprises a first connecting body with a first tightness and a second connecting body with a second tightness, the first connecting body and the second connecting body are connected to each other, and in a case that the connecting device rotates by various angles, the first connecting body and the second connecting body cooperatively bend without appearing a crease or a fold.

15. The connecting device according to claim 14 , wherein the hinge assembly comprises at least two multispindle hinges, and the filler fills a gap between the at least two multispindle hinges.

16. The connecting device according to claim 15 , wherein the filler is an arc-shaped structure, and an arc-shaped side wall of the arc-shaped structure is provided with at least one through hole passing through the arc-shaped side wall along an extending direction of the arc-shaped side wall.

17. The connecting device according to claim 16 , wherein the multispindle hinge comprises a plurality of spindles parallel to each other, adjacent spindles are connected to each other via a connector, and a spindle located at the edge of the multispindle hinges is provided with a connecting rod, wherein connecting rods at a first side of the multispindle hinges are fixedly connected to the first mounting plate, and connecting rods at a second side of the multispindle hinges are fixedly connected to the second mounting plate, and the number of the spindles in the multispindle hinges is the same as the number of the through holes in the filler.

18. The connecting device according to claim 17 , further comprising a second enveloping mechanism located between adjacent fillers and enveloping the connector.
