In this design, the first elastic body 41a, the second elastic body 41b, the third elastic body 41c and the fourth elastic body 41d are arranged close to the edge of the shell assembly 20a, so that stress points between the charging body 20 and the mounting shell 10 are distributed around the charging body 20 as much as possible, and the connection stability between the charging body 20 and the mounting shell 10 is further enhanced.

Further, as shown in fig. 6, in some embodiments, the first side 227 of the housing assembly 20a and the second side 228 of the housing assembly 20a are opposite sides along the length of the housing assembly 20 a. In this design, through setting up first elastomer 41a and second elastomer 41b along the length direction of shell subassembly 20a, can avoid first elastomer 41a and second elastomer 41b too close in the space, and the same thing, third elastomer 41c and fourth elastomer 41d set up along the length direction of shell subassembly 20a, and third elastomer 41c and fourth elastomer 41d are too close in the space for the comparatively dispersion of the distribution of the strong point between charging body 20 and the installation shell 10, thereby reach the even effect of further reinforcing the connection stability between charging body 20 and the installation shell 10 of atress.

Of course, in other embodiments, the case assembly 20a includes a bottom case 23, a top case 21, and a middle case 22, the middle case 22 having a first opening 111 facing the bottom case 23, a second opening 111 facing the top case 21, and a receiving chamber 20c in communication with the first opening 111 and the second opening 111, the receiving chamber 20c for receiving the circuit board assembly 20b, the bottom case 23 being connected with the middle case 22 to cover the first opening 111, and the top case 21 being connected with the middle case 22 to cover the second opening 111.

Further, in some embodiments, the middle shell 22 includes a first shell (not shown) and a second shell (not shown), where the first shell is connected to the second shell via a clamping structure, so that the first shell and the second shell jointly enclose the accommodating chamber 20c. In this design, by designing the middle case 22 to be divided into the first case and the second case, the overall structural strength of the middle case 22 can be enhanced; the first shell and the second shell are connected through the clamping structure, so that the assembly difficulty between the first shell and the second shell can be effectively reduced relative to the connection between the first shell and the second shell through the mode of screw connection. Specifically, the clamping structure comprises a clamping block and clamping grooves, the number of the clamping blocks and the clamping grooves is multiple, at least one of the clamping blocks and the clamping grooves is arranged on one side, close to the second shell, of the first shell, at least one other of the clamping blocks and the clamping grooves is arranged on one side, close to the first shell, of the second shell, and the clamping blocks are matched with the clamping grooves to achieve relative fixing of positions between the first shell and the second shell.

Of course, as shown in fig. 7-8, in other embodiments, a plurality of stopping members 113 are disposed on a side of the mounting shell 10 opposite to the first appearance surface 11, the number of stopping members 113 is equal to the number of openings 111, each stopping member 113 is disposed corresponding to one opening 111, and when the elastic body 41 is engaged with the corresponding opening 111, the elastic body 41 is also abutted with the corresponding stopping member 13. Specifically, the stopper 13 includes a stopper plate that forms an integral structure with the mounting case 10 by injection molding. Since the lengths of all the elastic bodies 41 are the same, when the inclination angles of all the elastic bodies 41 with respect to the symmetry plane of the shell assembly 20a are different, by designing the abutting piece 13, the elastic bodies 41 abut against the abutting piece 13, so that the inclination angles of all the elastic bodies 41 with respect to the symmetry plane of the shell assembly 20a can be effectively ensured to be consistent.
