Illustratively, an example in which the first receiving chamber 102 is formed on the lower housing 1011b is shown in the present embodiment. The first connector 11 and the first waterproof ring 12 are disposed in the first accommodating cavity 102, and the first waterproof ring 12 is in interference fit with at least one of the upper housing 1011a and the lower housing 1011 b.

The first connector 11 is embedded in the first accommodating cavity 102, and forms a first gap with the battery shell 101; at least a part of the thickness of the first waterproof ring 11 is larger than the width of the first gap so that the battery case 101 forms a pre-pressing action on the first waterproof ring 11.

It should be noted that the first gap between the first connector 11 and the battery case 101 may be a reasonable installation gap that needs to be reserved in order to facilitate installation of the first connector 11 into the first accommodating cavity 102 of the battery case 101, and the width of the first gap may be a distance between an inner wall of the battery case 101 and an outer wall of the first connector 11 in a direction along the battery case 101 to the first connector 11. Accordingly, the thickness of the first waterproof ring 11 may be a distance between the first waterproof ring 11 and a surface of the battery case 101 to a surface adjacent to the first connector 11 in a direction along the battery case 101 to the first connector 11 with the first waterproof ring 11 fitted in the first gap. That is, at least a part of the thickness of the first waterproof ring 11 is larger than the width of the first gap, and may be such that, in a direction from the battery case 101 to the first connector 11, a distance from a surface of the first waterproof ring 11 and the battery case 101 to a surface adjacent to the first connector 11 is at least partially larger than a distance between an inner wall of the battery case 101 and an outer wall of the first connector 11.

In an alternative embodiment of the present invention, the battery 10 further includes a first substrate 103, the first connector 11 is fixed to the first substrate 103, and the first substrate 103 is movably connected to the battery housing 101, such that the first connector 11 is movably connected to the battery housing 101.

Specifically, the first connector 11 may be fixed in the first substrate 103 by a connection method such as a soldering connection or a fastening connection, and the first substrate 103 may be electrically connected to the battery 10. Since the first substrate 103 is movably connected to the battery case 101, the first connector 11 can be movably connected to the battery case 101 through the first substrate 103, thereby achieving a floating effect. In one embodiment, the first substrate is a circuit board.

Referring to fig. 5, a schematic structural diagram of the first circuit board, the first connector and the first waterproof ring according to the embodiment of the present invention is shown, referring to fig. 6, an axial structural diagram of the structure shown in fig. 5 is shown, referring to fig. 7, a schematic structural diagram of a first waterproof ring according to the embodiment of the present invention is shown in a forward direction, and referring to fig. 8, a schematic structural diagram of the first waterproof ring shown in fig. 7 in a reverse direction is shown.

In the embodiment of the present invention, the first connector 11 is provided with a first plugging port 111 on a side away from the first substrate 103; the battery case 101 is provided with a first opening 104 at a position opposite to the first insertion/extraction opening 111, and the area of the first opening 104 is larger than the area of the first insertion/extraction opening 111.

Specifically, the first connector 11 can be connected to the second connector of the unmanned aerial vehicle through the first plug port 111. Because the battery shell 101 is provided with the first opening 104 at the position opposite to the first plug opening 111, and the area of the first opening 104 is larger than that of the first plug opening 111, the battery shell 101 can be prevented from blocking the first plug opening 111, and the first plug opening 111 and the second connector can be conveniently connected in a plug manner.

Optionally, the first waterproof ring 12 may include a first blocking portion 121, a first side wall portion 122, and a first flanging portion 123, which are connected in sequence, the first blocking portion 121 may be configured to block a gap between the first insertion and extraction opening 111 and the first opening 104, so as to prevent external water from entering the battery 10 through water between the first insertion and extraction opening 111 and the first opening 104, the first side wall portion 122 is embedded between the battery case 101 and the side wall of the first connector 11, and the first flanging portion 123 is embedded between the battery case 101 and the first substrate 103, so as to further prevent external water from entering the battery 10 through water between the battery case 101 and the side wall of the first connector 11 and between the battery case 101 and the first substrate 103, and improve the waterproof performance of the battery assembly.

In the embodiment of the present invention, a first groove 112 is disposed on an outer side wall of the first connector 11 at a position close to the first insertion/extraction opening 111, and a first end of the first blocking portion 121 is embedded in the first groove 112; the battery case 101 is provided with a second groove 105 at a position opposite to the first groove 112, and the second end of the first plugging portion 121 is embedded in the second groove 105 to plug a gap between the first plugging port 111 and the first opening 104.

Specifically, since the first end of the first blocking portion 121 is embedded in the first groove 112 of the outer side wall of the first connector 11, and the second end is embedded in the second groove 105 of the battery case 101, the fixing reliability of the first blocking portion 121 between the first connector 11 and the battery case 101 can be improved, and the waterproof stability of the first blocking portion 121 is further improved.

In the embodiment of the present invention, a first back adhesive layer 124 is disposed on a surface of the first flanging part 123 away from the first substrate 103, and the first back adhesive layer 124 may be made of an adhesive medium such as glue or tape. The first back glue layer 124 can be used for being bonded with the battery shell 101, so that the connection reliability between the first flanging part 123 and the battery shell 101 is improved, and the waterproof effect of the first waterproof ring 11 is further improved.

Alternatively, the thickness of the first blocking portion 121 may be greater than the thickness of the first side wall portion 122, and the thickness of the first burring portion 123. In practical applications, when external water enters the interior of the battery 10, the external water needs to pass through the first blocking portion 121 before entering the first side wall portion 122 and the first flanging portion 123, so that the waterproof performance of the first blocking portion 121 is better than that of the first side wall portion 122 and the first flanging portion 123 under the condition that the thickness of the first blocking portion 121 is greater than that of the first side wall portion 122 and that of the first flanging portion 123.

Specifically, at least a part of the thickness of the first blocking portion 121 is greater than the gap between the first inserting/extracting opening 111 and the first opening 104, so that the battery case 101 and the first blocking portion 121 are in interference fit, the battery case 101 forms a pre-pressing effect on the first blocking portion 121, and a first pre-pressing and waterproof effect is achieved.

Specifically, at least a part of the thickness of the first flanging part 123 is greater than the gap between the battery case 101 and the first substrate 103, so that the battery case 101 and the first flanging part 123 are in interference fit, and the battery case 101 forms a pre-pressing effect on the first flanging part 121, thereby achieving a second pre-pressing waterproof effect.

In some alternative embodiments of the invention, the first flashing ring 11 is a flexible flashing ring. In practical applications, in the case that the first waterproof ring 11 is a flexible waterproof ring, the first waterproof ring 11 can achieve the waterproof effect through flexible deformation.

Illustratively, the flexible waterproof ring is a silica gel waterproof ring, or the flexible waterproof ring is a rubber waterproof ring, or the flexible waterproof ring is a foam waterproof ring.

In practical applications, a person skilled in the art may select a specific type of the flexible waterproof ring according to actual needs, and the embodiment of the present invention is not limited by contrast.

In some alternative embodiments of the present invention, the first substrate 103 may be provided with a first deformation element 106, and the first substrate 103 is movably connected to the battery housing 101 through the first deformation element 106.

Specifically, the first deformation member 106 can be made of a deformable material, and since the first deformation member 106 is disposed on the first substrate 103, under the condition that the first deformation member 106 is movably connected to the inner wall of the battery case 101, and the first substrate 103 moves relative to the battery case 101, the first deformation member 106 can extrude the battery case 101 to realize deformation, and further, the first connector 11 fixed on the first substrate 103 can move relative to the battery case 101, so that the floating effect is realized.

Referring to fig. 11, which shows a schematic diagram of a connection structure of a first deformation element according to an embodiment of the present invention, and fig. 12, which shows an enlarged view of a position B of the first deformation element shown in fig. 11, as shown in fig. 11 and 12, a connection post 107 is disposed on a battery case 101, a first deformation element 106 may be a cylindrical deformation element having a through hole in a central region, a through hole may be disposed on a first substrate 103, the first deformation element 106 may be embedded in the through hole of the first substrate 103, and the through hole of the first deformation element 106 may be sleeved outside the connection post 107 of the battery case 101. In this way, when the first substrate 106 moves relative to the battery casing 101, the first deformation member 101 can press the connection post 107 on the battery casing 101 to deform, so that the first connector 11 fixed on the first substrate 103 can move relative to the battery casing 101 to achieve a floating effect.

It is understood that, since the deformation direction of the first deformation member 106 is arbitrary, that is, the deformation direction of the first deformation member 106 can be X-direction, Y-direction or a combination thereof with respect to the first substrate 103, accordingly, the first substrate 103 can be made movable in the X-direction, Y-direction or a combination thereof with respect to the battery case 101, so that the first connector 11 fixed on the first substrate 103 can be made to float with respect to the battery case 101.

Optionally, the first deformation element 106 is an elastic element, that is, the deformation of the first deformation element 106 may be elastic deformation, so that after the connection between the first connector 11 and the second connector is released, the first deformation element 106 may be restored to a non-deformed state, which is convenient for the first deformation element 106 to deform next time.

For example, the elastic member may be at least one of a spring, a spring plate, an elastic pad, and a torsion spring, and the embodiment of the present invention may not be limited to the specific form of the elastic member.

Optionally, the first deformation element may also be any one of a foam element, a silicone element, or a rubber element, which is not particularly limited in this embodiment of the present invention.

It is understood that, in practical applications, a person skilled in the art may configure the first deforming member 106 as an elastic member, a foam member, a silicone member, or a rubber member according to actual needs, and the specific type of the first deforming member 106 in the embodiment of the present invention may not be limited.

In some alternative embodiments of the present invention, the first surface of the first substrate 103 is movably connected to the battery case 101; the first connector 11 is fixed to a first surface of the first substrate 103. That is, the first deforming member 106 and the first connector 11 are disposed on the same surface of the first substrate 103.

In practical applications, when the first deformation element 106 deforms to move the first substrate 103 relative to the battery case 101, since the first deformation element 106 and the first connector 11 are disposed on the same surface of the first substrate 103, the movement can be rapidly transmitted to the first connector 11, so that the first connector 11 can correspondingly move relative to the battery case 101, and the floating efficiency of the first connector 11 is improved.

Alternatively, the first substrate 103 may be a printed circuit board, and since the printed circuit board has better rigidity than the flexible circuit board, in the case that the first substrate 103 is a printed circuit board, reliable support of the first connector 11 and the first deformation element 106 by the first substrate 103 can be achieved.

In summary, the battery assembly provided by the embodiment of the invention at least has the following advantages:
