Abstract

A detachable battery rack includes a battery rack body, an anode end portion and a cathode end portion, wherein the battery rack body includes at least two rack panels which defines a battery cavity to install batteries, wherein the anode end portion, which is detachable mounted to the battery rack body, includes an anode conductive plate detachably coupled to the rack panels, and the cathode end portion, which is detachable mounted to the battery rack body, includes a cathode conductive plate detachably coupled to the rack panels, wherein the anode conductive plate and the cathode conductive plate are respectively provided at two opposite sides of the rack panels.

Claims

1. A detachable battery rack, comprising:

a battery rack body which comprises two or more rack panels, wherein each of said rack panels comprises a side panel, and first and second end panels transversely extended from two opposite ends of said side panel respectively to define an opening and a battery cavity for receiving one or more batteries between said first and second end panels;

an anode end portion which comprises an anode conductive plate detachably coupled with said first end panels of said rack panels; and

a cathode end portion which comprises a cathode conductive plate detachably coupled with said second end panels of said rack panels.

2. The detachable battery rack, as recited in claim 1, wherein anode end portion further comprises a plurality of anode retention holes formed at said anode conductive plate and a plurality of anode retention posts formed at said first end panels of said rack panels respectively to penetrate through said anode retention holes respectively so as to detachably couple said first end panels of said rack panels with said anode conductive plate.

3. The detachable battery rack, as recited in claim 2, wherein anode end portion further comprises a plurality of cathode retention holes formed at said cathode conductive plate and a plurality of cathode retention posts formed at said second end panels of said rack panels respectively to penetrate through said cathode retention holes respectively so as to detachably couple said second end panels of said rack panels with said cathode conductive plate.

4. The detachable battery rack, as recited in claim 3, wherein said anode end portion further comprises an anode cover, an anode conductive end cap penetrating said anode cover and extending outside of said anode cover, and at least one anode fastening member fastening said anode cover with said anode conductive plate to cover said anode conductive plate within said anode cover.

5. The detachable battery rack, as recited in claim 4, wherein said cathode end portion further comprises a cathode cover, at least one cathode elastic member connected to said cathode conductive plate and at least one cathode fastening member fastening said cathode cover with said cathode conductive plate, so as to cover said cathode conductive plate within said cathode cover, wherein said cathode elastic member is a spring.

6. The detachable battery rack, as recited in claim 5, further comprising a cathode conductive terminal post, wherein said cathode cover further has a central through hole that said cathode conductive terminal post being interchangeably plugged into said central through hole to connect to said cathode conductive plate.

7. The detachable battery rack, as recited in claim 6, wherein said anode end portion further comprises a conductive elastic member inserted in said anode conductive end cap.

8. The detachable battery rack, as recited in claim 7, further comprising a stopper collar provided at a bottom of said anode conductive end cap for preventing said anode conductive end cap from escaping from said anode cover.

9. The detachable battery rack, as recited in claim 4, wherein said anode end portion further comprises a conductive elastic member inserted in said anode conductive end cap.

10. The detachable battery rack, as recited in claim 9, further comprising a stopper collar provided at a bottom of said anode conductive end cap for preventing said anode conductive end cap from escaping from said anode cover.

11. The detachable battery rack, as recited in claim 5, wherein said cathode end portion further comprises at least one connecting member having a middle retaining slot, wherein said cathode conductive plate has at least one through hole and said cathode cover has at least one retaining groove, wherein said connecting member is received in said retaining groove and passes through said through hole, wherein said cathode elastic member is embodied as a coil spring which comprises an end which is retained in said middle retaining slot of said connecting member.

12. The detachable battery rack, as recited in claim 1, wherein said anode end portion further comprises an anode cover, an anode conductive end cap penetrating said anode cover and extending outside of said anode cover, and at least one anode fastening member fastening said anode cover with said anode conductive plate to cover said anode conductive plate within said anode cover.

13. The detachable battery rack, as recited in claim 12, wherein said cathode end portion further comprises a cathode cover, at least one cathode elastic member connected to said cathode conductive plate and at least one cathode fastening member fastening said cathode cover with said cathode conductive plate, so as to cover said cathode conductive plate within said cathode cover, wherein said cathode elastic member is a spring.

14. The detachable battery rack, as recited in claim 13, further comprising a cathode conductive terminal post, wherein said cathode cover further has a central through hole that said cathode conductive terminal post being interchangeably plugged into said central through hole to connect to said cathode conductive plate.

15. The detachable battery rack, as recited in claim 1, wherein each of said side panels comprises a middle ridge protruded at a middle of an inner side of said side panel, wherein when said rack panels are coupled with each other, said battery cavities are separated by said middle ridges.

16. The detachable battery rack, as recited in claim 1, wherein each of said rack panels further comprises at least one retention rib protruded along an edge of each of said side panels and is extended into said opening.
