Abstract

Embodiments of the present application relate to a power supply device, including a housing, a circuit board and a connecting assembly. The housing defines an accommodation space, and includes: a housing positioning component, a first opening, and a second opening. The housing positioning component is disposed in the accommodation space. The circuit board is disposed in the accommodation space, and includes: a circuit board positioning component, a power input port, and a power output port. The power input port is disposed corresponding to the first opening. The power output port is disposed corresponding to the second opening, and electrically connected to the power output port. The connecting assembly is configured to connect the housing positioning component and the circuit board positioning component, and position the circuit board in the accommodation space of the housing.

First claim

What is claimed is:

1. A power supply device, comprising:
a housing, defining an accommodation space, and comprising:
a housing positioning component, disposed in the accommodation space; and
a first opening and a second opening;

a circuit board, disposed in the accommodation space, and comprising:
a power input port, mounted on the circuit board and disposed corresponding to the first opening; and
a power output port, mounted on the circuit board and disposed corresponding to the second opening, and electrically connected to the power input port; and
a circuit board positioning component, formed on the circuit board and adjacent to one side of the power output port; and

a connecting assembly, configured to connect the housing positioning component and the circuit board positioning component, and configured to position the circuit board in the accommodation space of the housing.

2. The power supply device according to claim 1 , wherein the first opening is formed on a top surface of the housing, the second opening is formed on a side surface of the housing, and the top surface and the side surface are adjacent to each other.

3. The power supply device according to claim 2 , wherein the power input port receives a power input element along a first direction, the power output port receives an electronic device along a second direction, and an angle between the first direction and the second direction is about 45 degrees to 135 degrees.

4. The power supply device according to claim 1 , wherein the power output port extends through the first opening, and protrudes from an outer surface of the housing.

5. The power supply device according to claim 1 , wherein the housing further comprises:
a bottom cap, removably disposed at a bottom portion of the housing.

6. The power supply device according to claim 1 , wherein the circuit board further comprises:
a light emitting element, disposed on the circuit board, and electrically connected to the power input port and the power output port.

7. The power supply device according to claim 6 , further comprising:
a light-emitting-element shield, disposed on the circuit board and corresponding to the light emitting element, and configured to cover the light emitting element.

8. The power supply device according to claim 7 , wherein the material of the light-emitting-element shield comprises an ethylene-vinyl acetate copolymer.

9. The power supply device according to claim 1 , further comprising:
a power storage element, disposed in the accommodation space, and electrically connected to the power input port.

10. The power supply device according to claim 9 , wherein in the accommodation space, the circuit board is disposed between the top surface of the housing and the power storage element.

11. The power supply device according to claim 10 , further comprising:
a buffer element, disposed in the accommodation space, and disposed between the power storage element and the circuit board.

12. The power supply device according to claim 11 , wherein a surface of the buffer element is opposite a surface of the power storage element, and the area of the surface of the buffer element is substantially equal to the area of the surface of the power storage element.

13. The power supply device according to claim 11 , wherein the material of the buffer element comprises an ethylene-vinyl acetate copolymer.

14. The power supply device according to claim 10 , further comprising:
a buffer element, disposed in the accommodation space, and disposed between the power storage element and the bottom cap of the housing.

15. The power supply device according to claim 14 , wherein a surface of the buffer element is opposite to a surface of the power storage element, and the area of the surface of the buffer element is substantially equal to the area of the surface of the power storage element.

16. The power supply device according to claim 14 , wherein the material of the buffer element comprises an ethylene-vinyl acetate copolymer.

17. The power supply device according to claim 1 , wherein the connecting assembly comprises at least one screw, the circuit board positioning component comprises at least one through hole, the housing positioning component comprises at least one screw hole corresponding to the at least one through hole, and the at least one screw extends through the at least one through hole and is connected to the at least one screw hole.

18. The power supply device according to claim 1 , wherein the connecting assembly comprises two screws, the circuit board positioning component comprises two through holes, the housing positioning component comprises two screw holes corresponding to the two through holes, and the two screws respectively extend through the two through holes and are connected to the two screw holes.

19. The power supply device according to claim 18 , wherein the two through holes are respectively disposed on two sides of the power output port.

20. The power supply device according to claim 1 , wherein the power output port comprises one of a universal serial bus (USB) output port, a mini USB output port, a micro USB output port or a USB-C output port.

21. The power supply device according to claim 1 , wherein the power input port comprises one of a USB input port, a mini USB input port, a micro USB input port or a USB-C input port.
