Abstract

A battery mounting apparatus includes a mounting plate configured to hold a battery, a locking structure configured to detachably attach the battery to the mounting plate, and an ejection structure configured to eject the battery when the locking structure releases the battery, such that at least a portion of the battery is separated from the mounting plate.

First claim

What is claimed is:

1. A battery mounting apparatus comprising:
a mounting plate configured to hold a battery;
a locking structure configured to detachably attach the battery to the mounting plate; and
an ejection structure configured to eject the battery when the locking structure releases the battery, such that at least a portion of the battery is separated from the mounting plate, the ejection structure comprising:
an ejection part comprising:
a sliding slot member; and
a fastening member adjacent to the sliding slot member; and

an elastic part made of an elastic material, one end of the elastic part being fastened to the fastening member, and another end of the elastic part being fastened to the mounting plate.

2. The apparatus of claim 1 , wherein:
the mounting plate comprises a first sliding structure;
the battery comprises a second sliding structure configured to be slidably coupled with the first sliding structure; and
when the ejection structure ejects the battery, at least a portion of the second sliding structure is separated from the first sliding structure.

3. The apparatus of claim 2 , wherein:
the ejection part further comprises an ejection slider;
when the battery is in a mounted state, the ejection slider contacts one end of the battery, and the elastic part is stretched; and
when the battery is released by the locking structure, the elastic part releases an elastic force to eject the ejection part, such that the ejection slider pushes at least a portion of the second sliding structure out of the first sliding structure.

4. The apparatus of claim 3 , wherein:
the first sliding structure comprises a sliding slot comprising an ejection structure opening provided at a position corresponding to the ejection part;
the second sliding structure of the battery comprises a protruding stripe configured to be coupled with the sliding slot;
the ejection part is arranged at a side of the mounting plate facing away from the battery; and
a portion of the ejection slider is exposed through the ejection structure opening, the portion of the ejection slider pressing against the one end of the battery when the battery is in the mounted state.

5. The apparatus of claim 4 , wherein:
the sliding slot member is in communication with the sliding slot of the mounting plate to allow the protruding stripe to slide in the sliding slot member and the sliding slot; and
the ejection slider is arranged in the sliding slot member.

6. The apparatus of claim 5 , wherein:
the fastening member is a first fastening member;
the ejection part further comprises a second fastening member;
the elastic part comprises two spring coils disposed on two sides of the sliding slot member, respectively, and corresponding to the first fastening member and the second fastening member, respectively;
one end of each of the two spring coils is fastened to a mounting post of a corresponding one of the first fastening member and the second fastening member; and
another end of each of the two spring coils is fastened to a mounting post of the mounting plate at the ejection structure opening.

7. The apparatus of claim 6 , further comprising:
an ejection guide structure comprising a guide member corresponding to the ejection part and configured to guide the ejection part when the ejection part moves.

8. The apparatus of claim 7 ,
wherein the mounting plate is a first mounting plate, the ejection structure is a first ejection structure, and the battery is a first battery;
the battery mounting apparatus further comprising:
a second mounting plate arranged parallel to the first mounting plate and having an identical structure as the first mounting plate, the second mounting plate being configured to hold a second battery; and
a second ejection structure having an identical structure as the first ejection structure and located in a receiving space defined by the ejection guide structure and a plurality of separation plates of the second mounting plate, the second ejection structure being configured to, when the second battery is released, eject the second battery, such that at least a portion of the second battery is separated from the second mounting plate;
wherein the first ejection structure, the second ejection structure, and the ejection guide structure are located between the first mounting plate and the second mounting plate.

9. The apparatus of claim 4 , wherein:
the elastic part is a first elastic part; and
the locking structure comprises:
a locking part comprising a body and a locking slider protruding from the body; and
a second elastic part, one end of the second elastic part being fastened to the mounting plate and another end of the second elastic part being fastened to the body, the second elastic part being configured to:
during a process of the locking part locking the battery to the mounting plate, undergo a first deformation;
when the battery is locked to a pre-determined position on the mounting plate, undergo a second deformation opposite to the first deformation to press the locking part, such that the locking slider locks the battery; and
when the locking part releases the battery, undergo the first deformation to allow the locking slider to release the first battery.

10. The apparatus of claim 9 , wherein:
the mounting plate further comprises a locking structure opening adjacent to the locking part and comprising a first portion at the sliding slot and a second portion at a plate body of the mounting plate, the second portion being in communication with the first portion;
when the locking slider is located at the first portion, the locking part locks the battery to the mounting plate; and
when the locking slider is pushed, the locking slider moves from the first portion to the second portion to release the battery.

11. The apparatus of claim 10 , wherein:
the locking slider comprises a force bearing surface arranged perpendicular to the mounting plate and inclined with respect to the sliding slot, and when the protruding stripe of the battery slides into the sliding slot, the battery presses against the force bearing surface to move the locking slider from the first portion to the second portion; and/or
the locking slider comprises a recess adjacent to the second sliding structure of the battery, and the second sliding structure of the first battery comprises a rib corresponding to and accommodated in the recess.

12. The apparatus of claim 9 , wherein:
the locking part also comprises an in-position resisting member extending from the body and arranged at a side of the mounting plate facing away from the battery;
the mounting plate further comprises a contacting member corresponding to the in-position resisting member; and
when the battery is mounted to the mounting plate, the in-position resisting member presses against the contacting member to lock the battery.

13. The apparatus of claim 12 , wherein:
the mounting plate further comprises an abutting member extending approximately vertically from the plate body, the body of the locking part comprises an opening at a center of the body and penetrating the body, the abutting member extends into the opening of the body, the second elastic part is located in the opening of the body, and two ends of the second elastic part press against the abutting member and the body, respectively; and/or
the second elastic part comprises a spring coil, one end of the spring coil being fastened to a mounting post of the abutting member, and another end of the spring coil being fastened to a mounting post of the body; and/or
the locking part further comprises a pressing m
