Wearable device

1. A wearable device comprising:

a main body;

a housing; and

at least one connection element fixed to the housing, each of the at least one connection element comprising:

a body; and

at least one elastic protrusion protruding from one side of the body, wherein the at least one elastic protrusion and the body are double color molded, the body is made of plastic and the at least one protrusion is made of rubber;

wherein when mounting the main body to the housing, the at least one elastic protrusion of each of the at least one connection element is deformed to generate elastic force to fix the main body in the housing.

2. The wearable device as described in claim 1 , wherein the number of the at least one connection element is two and the two connection elements are respectively fixed to two opposite inner walls of the housing.

3. The wearable device as described in claim 2 , wherein the inner wall of the housing defines two first recesses for respectively receiving the two connection elements.

4. The wearable device as described in claim 1 , wherein each of the at least one connection element is fixed to the housing by gluing the at least one connection element to the housing.

5. The wearable device as described in claim 1 , wherein a pole is defined on the at least one elastic protrusion, a corresponding blind hole matching the pole is defined on the housing to receive the pole.

6. The wearable device as described in claim 1 , wherein each of the at least one elastic protrusion forms a recess on an opposite side of the body, the at least one connection element includes at least one elastic element, one of the at least one recess receives one of the at least one elastic element.

7. The wearable device as described in claim 6 , wherein each of the elastic element is arc shaped and is made of stainless steel.

8. A wearable device comprising:

a main body;

a housing; and

at least one connection element fixed to the housing, each of the at least one connection element comprising:

a body; and

at least one elastic protrusion protruding from one side of the body, each of the at least one elastic protrusion forms a recess on an opposite side of the body; and

at least one elastic element, one of the at least one recess receiving one of the at least one elastic element;

wherein when mounting the main body to the housing, the at least one elastic element of each of the at least one connection element is deformed to generate elastic force to fix the main body in the housing.

9. The wearable device as described in claim 8 , wherein the number of the at least one connection element is two and the two connection elements respectively fixed to two opposite inner walls of the housing.

10. The wearable device as described in claim 9 , wherein the inner wall of the housing defines two first recesses for respectively receiving the two connection elements.

11. The wearable device as described in claim 8 , wherein each of the at least one connection element is fixed to the housing by gluing the at least one connection element to the housing.

12. The wearable device as described in claim 8 , wherein the at least one elastic protrusion and the body are double color molding, the body is made of plastic and the at least one protrusion is made of rubber.

13. The wearable device as described in claim 8 , wherein a pole is defined on the at least one elastic protrusion, a corresponding blind hole matching the pole is defined on the housing to receive the pole.

14. A wearable device comprising:

a main body;

a housing comprising an inner wall, the inner wall defining two recesses, a bottom of each of the two recesses defining at least one holes; and

at least one connection element defining at least one screw hole, at least one screw passing through the at least one hole and the at least one screw hole to fix the connection element to the housing, the at least one connection element being made of metal, each of the at least one connection element comprising:

a body; and

at least one elastic protrusion protruding from one side of the body;

wherein when mounting the main body to the housing, the at least one elastic element protrusion of each of the at least one connection element is deformed to generate elastic force to fix the main body in the housing.

15. The wearable device as described in claim 10 , wherein the metal is copper foil.

16. The wearable device as described in claim 10 , wherein two adjacent elastic protrusions protruding from the connection element are separated by a second hole.

17. The wearable device as described in claim 10 , wherein the number of the at least one elastic protrusion comprised in each of the at least one connection element is four.
