[0035] See also Figures 1-3 A lamp includes a housing 200, a lighting part 300, and a connector 400 connecting the housing 200 and the lighting part 300. A battery 100 and a control module 500 for driving the lighting part 300 are arranged in the housing 200, and the battery 100 and the control module 500 are electrically connected.

[0036] See also Figures 4-11 The battery 100 includes a shell 1, a battery cell 2, a charging interface 3, a contact group for electrical connection, and a control circuit board 5. The battery cell 2 and the control circuit board 5 are arranged in the shell 1. The control circuit board 5 can detect the power level, temperature and other status of the battery cell 2, and control the charging operation of the battery cell 2.

[0037] The outer shell 1 is elongated, its shape and size matching those of the battery cell 2. The outer shell 1 has opposing first and second ends 11, 12, along its length. The battery cell 2 and the first end 11 of the outer shell 1 can be spaced apart to create a certain accommodation space between them, within which the control circuit board 5 can be placed. A first groove 13 is formed on the outer wall of the outer shell 1 near the first end 11. This first groove 13 is formed by an inward depression in the outer wall of the outer shell 1 and extends through the first end 11. The first groove 13 can also communicate with the interior of the outer shell 1. There can be two or three first grooves 13, spaced circumferentially along the outer wall of the outer shell 1. In this embodiment, there are three first grooves 13. The contact assembly includes two or three contacts 4, the number and position of which correspond to the first grooves 13. Each contact 4 passes through the inner shell 1 and emerges from its corresponding first groove 13. Each contact piece 4 is electrically connected to the control circuit board 5 and the control module 500 respectively, thereby enabling the battery 100 to supply power to the power supply object (the lighting part 300 in this embodiment).

[0038] A second groove 14 is also formed on the outer peripheral wall of the housing 1 near the first end 11. The second groove 14 is formed by an inward depression of the outer peripheral wall of the housing 1 and extends through the first end 11. The second groove 14 can be larger than the first groove 13 and can be a flat rectangular parallelepiped as a whole. The above-mentioned charging interface 3 is disposed in the second groove 14, passing through the housing 1 and exposed in the second groove 14. The charging interface 3 is electrically connected to the control circuit board 5, which can control the on and off of the charging interface 3 to provide charging protection.

[0039] The battery 100 further includes an indicator light 6 provided on the first end portion 11 of the housing 1 . The indicator light 6 is electrically connected to the control circuit board 5 and is used to indicate the status of the battery cell 2 .

The second end 12 of the outer shell 1 is open, so that the outer shell 1 encloses a roughly cylindrical space to accommodate the battery cell 2. A bottom cover 7 is provided at the opening, and the battery cell 2 is inserted upward from the second end 12 into the outer shell 1, and then the bottom cover 7 is covered to fix the battery cell 2 in the outer shell 1. This installation method is very convenient and does not have the problem of difficulty in aligning the two half shells due to the long length of the outer shell 1 in the prior art. To facilitate the positioning of the battery cell 2 during installation, a second positioning groove 16 can be formed on the inner side of the first end 11 of the outer shell 1, and a protrusion 31 is formed on the charging port 3. The protrusion 31 is snapped into the second positioning groove 16 to complete the installation and positioning of the battery cell 2 and the outer shell 1.

[0041] The outer shell 1 and the bottom cover 7 can be fixed by snapping, plugging, gluing, etc., or ultrasonic fixing can be used. A first positioning groove 15 is formed on the inner peripheral wall of the outer shell 1, which is formed by the second end 12 being recessed in the direction of the first end 11. A positioning column 71 is provided on the bottom cover 7, and the positioning column 71 can match the first positioning groove 15. There can be two positioning columns 71 arranged at intervals, and the first positioning groove 15 also has two matching ones. During installation, first insert the positioning column 71 on the bottom cover 7 into the corresponding first positioning groove 15, and then fix the inner wall of the outer shell 1 and the bottom cover 7 by ultrasonic welding.

[0042] The common height of the shell 1 and the bottom cover 7 is H, the height of the bottom cover 7 is h, and the width of the bottom cover 7 at its maximum width is d. To make the structure compact, the value range of H is 75mm~79mm, the value range of h is 1.5mm~3mm, and the value range of d is 20mm~24mm.

[0043] An operating portion 17 is formed on the outer wall of the housing 1 near the second end 12 . The operating portion 17 is concave or convex, making it easy for fingers to pick up the device.

[0044] The battery 100 disclosed above in the present invention can also be used in other electrical appliances that adopt this type of power supply method, such as power tools.
