Abstract

A battery case for a robot has a housing and an end cap. The housing defines a chamber for receiving a battery therein. The chamber has an open end. The end cap includes a cap that is used to cover the open end, a rotatable post rotatably passing through the cap and extending into the chamber, an elastic member arranged around the rotatable post and comprising an end abutting against the cap, and a locking member connected to the rotatable post and rotatable together with the rotatable post to a position where the locking member is engaged with the housing, thus locking the cap to the housing.

First claim

What is claimed is:

1. An assembly comprising:
a torso portion of a robot; and
a battery case arranged in the torso portion, the battery case comprising a housing and an end cap, the housing defining a chamber for receiving a battery therein, the chamber having an open end, the end cap comprising a cap that is configured to cover the open end, a rotatable post rotatably passing through the cap and extending into the chamber, an elastic member arranged around the rotatable post and comprising an end abutting against the cap, and a locking member connected to the rotatable post and rotatable together with the rotatable post to a position where the locking member is engaged with the housing, thus locking the cap to the housing.

2. The assembly according to claim 1 , wherein the housing defining a slot adjacent to the open end, the slot is configured to receive an end of the locking member when the locking member rotates to the position.

3. The assembly according to claim 1 , wherein the end cap further comprising a ring pull connected to the rotatable post, the ring pull is configured to receive an external force to rotate the rotatable post.

4. The assembly according to claim 3 , wherein the ring pull is rotatable connected to an outer end of the rotatable post, the cap defines a recess to receive the ring pull.

5. The assembly according to claim 1 , wherein the cap comprises one or more projections at an end opposite the rotatable post, and the housing defines one or more holes to receive the one or more projections therein.

6. The assembly according to claim 1 , wherein the battery comprises a positioning disc on one end thereof, and the cap comprises a receiving portion on an inner side thereof, the receiving portion is configured to receive the positioning disc so as to position the battery.

7. The assembly according to claim 6 , wherein the positioning disc is rectangular and the battery comprises a connecting post protruding from the end thereof, the positioning disc is connected to the connecting post, the receiving portion defines a groove to receive the connecting post and comprises a projection protruding from a side of the groove, the connecting post defines a notch to fit the projection therein so as to hold the positioning disc in position.

8. The assembly according to claim 1 , wherein the battery comprises a positive terminal and a net terminal at an end opposite the positioning disc, the housing defines two through holes through which the positive terminal and the negative terminal are connected to an external load.

9. The assembly according to claim 8 , further comprising a circuit board fixed to the housing at an end of the end cap, wherein the circuit board is electrically connected to the battery, the circuit board comprises two set of retractable pins that are respectively arranged corresponding to and abut against the positive terminal and the negative terminal and a port configured to connect with an external circuit.

10. A robot comprising:
a torso portion; and
a battery case arranged in the torso portion, the battery case comprising a housing and an end cap, the housing defining a chamber for receiving a battery therein, the chamber having an open end, the end cap comprising a cap that is configured to cover the open end, a rotatable post rotatably passing through the cap and extending into the chamber, an elastic member arranged around the rotatable post and comprising an end abutting against the cap, and a locking member connected to the rotatable post and rotatable together with the rotatable post to a position where the locking member is engaged with the housing, thus kicking the cap to the housing.
