Referring further to fig. 4, 5 and 6, in some embodiments, the positioning member 2 includes a bracket 21 having a positioning cavity 211 and a closing member 22 for closing the receiving opening 12, the closing member 22 is connected to the bracket 21, the battery cell 4 is received in and positioned in the positioning cavity 211, and the locking member 31 and the detachment hole 5 are disposed on the closing member 22. In this embodiment, the receiving opening 12 of the housing 1 can be closed by the closing member 22 while the holder 21 with the battery cell 4 mounted therein is placed in the receiving chamber 11 of the housing 1. Simultaneously, the locking piece 31 and the dismounting hole 5 are arranged on the sealing piece 22, so that the assembly and the disassembly of the positioning piece 2 and the shell 1 are convenient. It should be noted that, the locking member 31 may be, but not limited to, a latch hook, a latch block, or a latch rod provided on the positioning member 2, and the locking member 31 may also have a certain elasticity, so that the locking member 31 can be stably locked in the latch slot 321.

Referring to fig. 4, 5 and 6, in some embodiments, the closing member 22 includes a positioning seat 221 for being inserted into the accommodating opening 12 and connected to the bracket 21, and a cover 222 for closing the accommodating opening 12, a step surface 23 for abutting against an end of the housing 1 is formed at a connection portion between the positioning seat 221 and the cover 222, the locking member 31 is protruding on an outer peripheral surface of the positioning seat 221, and the detachment hole 5 is formed in the cover 222. In this embodiment, when the locking member 31 on the positioning seat 221 is locked in the locking groove 321 of the housing 1, the stepped surface 23 at the connection portion between the positioning seat 221 and the cover 222 abuts against the end of the housing 1 having the receiving opening 12, so that on one hand, the locking member 31 is guaranteed to be tightly adhered to the groove wall of the locking groove 321, and on the other hand, friction between the closure member 22 and the housing 1 is increased, so that the closure member 22 is stably locked on the housing 1. In this way, the difficulty of rotating the closure 22 relative to the housing 1 is increased without the aid of a removal tool, thereby advantageously preventing the user from randomly removing the battery assembly 200. In addition, the locking piece 31 is provided with a guiding inclined plane 311, when the locking piece 31 is abutted against the sealing piece 22 by means of dismounting, the locking piece 31 can move a small distance along the axial direction of the shell 1 under the guiding action of the guiding inclined plane 311, the corresponding side surface of the locking piece 31 is prevented from being tightly attached to the groove wall of the locking groove 321, friction between the locking piece 31 and the groove wall of the locking groove 321 is reduced, and accordingly the dismounting tool is facilitated to drive the sealing piece 22 to rotate relative to the shell 1. Because the sealing piece 22 and the bracket 21 provided with the battery cell 4 are integrally formed, the sealing piece 22 can drive the bracket 21 to synchronously rotate in the process of rotating the sealing piece 22 relative to the shell 1, so that the positioning piece 2 can rotate relative to the shell 1.

In this embodiment, the portion of the sealing ring 7 protruding from the sealing groove 223 abuts against the inner wall of the housing 1, so that on one hand, the tightness can be improved, on the other hand, friction between the sealing member 22 and the housing 1 can be increased, and the difficulty of rotating the sealing member 22 relative to the housing 1 can be increased without using a disassembling tool, so that the battery assembly 200 can be prevented from being disassembled by a user.

Referring to fig. 2, 5 and 6, in some embodiments, the positioning element 2 is provided with a first elastic electrode 8, a first circuit board 9, a second elastic electrode 10 and a second circuit board 20, the first elastic electrode 8 is electrically connected to the first circuit board 9, the second elastic electrode 10 is electrically connected to the second circuit board 20, and the battery cell 4 is clamped between the first elastic electrode 8 and the second elastic electrode 10. Due to the elastic force of the first elastic electrode 8 and the second elastic electrode 10, the battery cell 4 is firmly clamped and positioned between the first elastic electrode 8 and the second elastic electrode 10, the contact tightness between the positive electrode and the negative electrode of the battery cell 4 and the first elastic electrode 8 and the second elastic electrode 10 is enhanced, and poor contact between the positive electrode and the negative electrode of the battery cell 4 and the first elastic electrode 8 and the second elastic electrode 10 is avoided. In addition, since the battery cell 4 is firmly clamped and positioned between the first elastic electrode 8 and the second elastic electrode 10, when the battery cell 4 is detached from the positioning member 2, only the elastic force of the first elastic electrode 8 and the second elastic electrode 10 needs to be overcome, so that the detachment and the installation of the battery cell 4 can be conveniently and rapidly realized, and the detachment, the replacement or the recycling of the battery cell 4 of the battery assembly 200 is convenient. In particular, the first elastic electrode 8 and/or the second elastic electrode 10 may be, but are not limited to, spring steel sheets in order to enhance the clamping force to the battery cell 4 and to increase the conductive contact area with the battery cell 4.

In some embodiments, the preset angle of rotation of the positioning member 2 relative to the housing 1 is 90 ° to 180 °, for example, the preset angle of rotation of the positioning member 2 relative to the housing 1 may be 90 °, 120 °, 150 ° or 180 °, etc., so that the locking structure 3 releases the locking connection between the positioning member 2 and the housing 1 due to the relatively large angle of rotation of the positioning member 2 relative to the housing 1 by means of the dismounting tool, which increases the difficulty of rotating the closure member 22 relative to the housing 1, thereby being beneficial for preventing the user or the child from arbitrarily dismounting the battery assembly 200.

Referring further to fig. 2 and 4 in combination, in some embodiments, in order to enhance the stability of the connection of the positioning member 2 with the housing 1 and to enhance the reliability of preventing the user from arbitrarily disassembling the battery assembly 200, the number of locking structures 3 is at least two, and at least two locking structures 3 are arranged at intervals along the circumferential direction of the positioning member 2. The positioning piece 2 is locked and fixedly connected to the shell 1 through at least two locking structures 3, so that the quick and stable assembly of the battery cell 4 can be realized.
