[0049] When assembling the functional box, the functional components need to be installed in the cavity 11 first, and then the sealing plate 5 is installed on the box body 1 through the third clamp 52 and the fastener 111. The sealing plate 5 is installed using the buckle structure, which is conducive to improving the assembly efficiency of the functional box.

[0050] Furthermore, the pin avoidance hole 51 is provided on the sealing plate 5 .

[0051] This embodiment also provides a power supply device, such as Figures 5 to 8 , including the above-mentioned functional box.

[0052] In some specific embodiments, reference Figures 5 to 8 The power supply device also includes a power box 10, a function box installation position 101 is provided on the power box 10, a first limiting hole 103 is provided on the function box installation position 101, and the first clamping member 211 includes a first clamping portion 2112, and the first clamping portion 2112 can enter the power box 10 through the first limiting hole 103 and be clamped on the power box 10.

[0053] Specifically, a function box installation position 101 is provided at a corner of the power box 10, and the function box installation position 101 includes a installation position bottom surface 1011 and a installation position side surface 1012. A first limiting hole 103 is provided on the installation position bottom surface 1011, and a clamping strip 102 is provided on the installation position side surface 1012. The clamping strip 102 is matched with the guide groove 13 on the box body 1.

[0054] Two first limiting holes 103 are provided on the bottom surface 1011 of the installation position to correspond to the first clamps 211 of the elastic mounting structure 2 at both ends of the function box. During installation, the two pressing members 21 are pressed simultaneously to bring the two first clamps 211 closer to each other, and then the first clamps 211 are extended into the corresponding first limiting holes 103 until the first clamps 211 present a state of "the first clamping portion 2112 is located in the power box 10, and the first connecting rod 2111 is inserted into the first limiting hole 103". Subsequently, the pressing member 21 is released, and under the action of the reset spring 3, the first connecting rod 2111 is pressed against the side wall of the first limiting hole 103, and the first clamping portion 2112 is clamped on the upper wall inside the power box 10 to limit the function box from moving away from the power box 10, and the function box is installed on the power box 10.

[0056] The cross section of the clamping strip 102 is T-shaped, and the cross section of the guide groove 13 is also T-shaped. The clamping strip 102 can enter the guide groove 13 from the bottom of the guide groove 13. When installing the function box, the guide groove 13 is first sleeved on the clamping strip 102, and then the function box is installed on the power box 10 by pressing and releasing the pressing member 21, which is conducive to quickly locating the relative position of the function box and the power box 10 and improving the installation speed. At the same time, the cross sections of the clamping strip 102 and the guide groove 13 are both T-shaped, which can limit the function box from being away from the installation side 1012, and further stabilize the position of the function box on the power box 10.

[0057] Furthermore, the length of the first connecting rod 2111 satisfies the following conditions: when the first clamping portion 2112 just enters the interior of the power box 10, the bottom of the function box just abuts against the bottom surface 1011 of the installation position, so that the first clamping portion 2112 can no longer extend into the interior of the power box 10; and after the pressing member 21 is released, the first clamping portion 2112 just clamps on the upper wall inside the power box 10. With such a configuration, the function box is less loose after being installed on the power box 10, and is not prone to abnormal noise, and the connection between the pin assembly 42 and the socket group is more stable, which is conducive to the stability of the function box structure.

[0058] In another embodiment, a clamping strip 102 is provided on the side surface 1012 of the positioning surface, and a guide groove 13 is provided on the box body 1 .
