Abstract
Claims
1. A charging device for charging at least one battery pack, the battery pack comprising a cuboid housing and at least one locking hook capable of being triggered by a user to move from an extended position protruding from a side wall of the housing to a retracted position flush with the side wall of the housing; the charging device comprising a housing defining at least one slot, each of the slots being shaped to fit the housing of the battery pack, the housing further comprising at least one locking groove capable of engaging with the at least one locking hook in the extended position to lock the battery pack in the corresponding slot; characterized in that, Each of the slots has an ejection mechanism at its bottom, the ejection mechanism including at least one spring, each of the springs being compressed when the battery pack is locked in the slot.
2. The charging device of claim 1, wherein, The battery pack includes a female charging terminal located at the bottom of the housing, and the bottom of the slot is provided with a male charging terminal that is compatible with the female charging terminal.
3. The charging device of claim 2, wherein, When the female charging terminal is connected to the male charging terminal, the female charging terminal moves a first stroke from the moment it first contacts the male charging terminal until it completes the electrical connection with the male charging terminal; the spring is configured to generate an elastic force after the battery pack is released from the corresponding slot, so that the corresponding battery pack generates a second stroke, the second stroke being greater than the first stroke.
4. The charging device of claim 1, wherein, The number of springs is one pair.
5. The charging device of claim 1, wherein, The ejection mechanism further includes a bracket and a pair of spring blocks. The bracket is fixedly disposed with the housing. Each of the springs is arranged between the bracket and one of the spring blocks. Each of the spring blocks abuts against the battery pack when the battery pack is locked in the slot.
6. The charging device of claim 1, wherein, The battery pack includes at least one operating button for a user to trigger the at least one locking hook to change from the extended position to the retracted position. The at least one operating button is located on the upper part of the battery pack, and the depth of the slot is configured to expose the at least one operating button when the battery pack is locked in the corresponding slot.
7. The charging device of claim 1, wherein, The housing defines a pair of slots, which are arranged side by side, either front to back or left to right.
8. The charging device of claim 7, wherein, The slots of the pair are at different heights.
