Abstract

An assembly for a robot includes a shoulder, an arm rotatably connected to the shoulder, an armor decorative member connected to the arm and located adjacent to the shoulder, and a connection assembly located between and rotatably connected to the arm and the armor decorative member. Relative rotation between the arm and the connection assembly and between the armor decorative member and the connection assembly enables the arm to continue to rotate after an upper end of the armor decorative member comes into contact with the shoulder.

First claim

What is claimed is:

1. An assembly for a robot, comprising:
a shoulder;
an arm rotatably connected to the shoulder;
an armor decorative member connected to the arm and located adjacent to the shoulder;
a connection assembly located between and rotatably connected to the arm and the armor decorative member, wherein relative rotation between the arm and the connection assembly and between the armor decorative member and the connection assembly enables the arm to continue to rotate after an upper end of the armor decorative member comes into contact with the shoulder; and
a connection shaft;
wherein the connection assembly comprises a first connection member, a second connection member, a first torsion spring and a second torsion spring, the first connection member comprises a first end rotatably connected to the armor decorative member and a second, opposite end, the second connection member comprises a first bar and a second bar, the second end of the first connection member is rotatably connected to the first bar, the first torsion spring is connected to the first connection member and configured to apply a restoring force to the armor decorative member, and the second torsion spring is connected to the first bar and the second bar and configured to return the first connection member and the second connection member to original orientation thereof with respect to the arm;
wherein the first end of the first connection member defines a first connection hole, and the armor decorative member defines a mounting hole, one end of the connection shaft is fixed in one of the first connection hole and the mounting hole, and an opposite end of the connection shaft is rotatable in the other one of the first connection hole and the mounting hole, thereby rotatably connecting the armor decorative member to the first connection member.

2. The assembly of claim 1 , wherein the second connection member further comprises a first connection support, a second connection support, opposite ends of the first bar are fixed to the first connection support and the second connection support at first ends thereof, and opposite ends of the second bar are fixed to the first connection support and the second connection support at second ends thereof.

3. The assembly of claim 2 , wherein the second connection member further comprises a first pin and a second pin, the first bar and the second bar are hollow, the first pin passes through, in sequence, the first end of the first connection support, the first bar and the first end of the second connection support so as to fix the first bar to the first connection support and the second connection support, and the second pin passes through, in sequence, the second end of the first connection support, the second bar and the second end of the second connection support so as to fix the second bar to the first connection support and the second connection support.

4. The assembly of claim 1 , wherein the first torsion spring comprises a coiled portion arranged around the connection shaft, a first arm extending from one end of the coiled portion and staying in contact with the armor decorative member, and a second arm extending from an opposite end of the coiled portion and connected to the first connection member.

5. The assembly of claim 1 , wherein the second torsion spring comprises a first coiled portion arranged around the second bar, and a second coiled portion arranged around the first bar and connected to the first coiled portion, and the second coiled portion is fixed tot the arm.

6. The assembly of claim 1 , wherein the second torsion spring comprises two first coiled portions arranged around the second bar and two second coiled portions arranged around the first bar and respectively connected to the two first coiled portions, a first arm extends from an end of each of the first coiled portions that is away from the second coiled portions, the two first arms are connected to each other to form a U shape.

7. The assembly of claim 6 , wherein the two second coiled portions are located at opposite sides of the second end of the first connection member.
