Description

Technical Field

[0001] The present disclosure relates to the electrical field, and in particular to a power supply device. Background Art

[0002] At present, the strong current sockets and weak current sockets that provide power output to users in RVs are installed separately. The strong current sockets are used to provide AC voltage to high-power electrical appliances on RVs, including, for example, two-hole interfaces, three-hole interfaces, etc. The weak current sockets are used to provide DC voltage to small electronic devices (for example, mobile phones, tablet computers, smart watches, etc.), which can be, for example, various types of USB interfaces, etc. The power input of the strong current sockets usually comes from external AC power or a vehicle-mounted generator, and the power input of the weak current sockets usually comes from the vehicle-mounted energy storage battery. The manufacturer of the RV needs to purchase these two types of socket products separately and open two mounting holes on the mounting wall of the RV for installation. This will obviously take up the already limited space on the RV and will also increase manufacturing costs. For the users of the RV, the two sockets installed separately do not seem simple and beautiful enough. Utility Model Content

[0003] In order to solve the defects of the power socket in the prior art, the present disclosure proposes a power supply device.

[0004] The first aspect of the present disclosure proposes a power supply device, including a shell, a high-current supply module, a low-current supply module, and an insulating member. A first cavity and a second cavity are provided inside the shell. The high-current supply module is provided in the first cavity, and is used to output a high-current voltage, and the power input of the high-current supply module comes from alternating current. The low-current supply module is provided in the second cavity, and is used to output a low-current voltage, and the power input of the low-current supply module comes from direct current. An insulating member is provided in the shell, and the insulating member insulates and isolates the high-current supply module from the low-current supply module.

The shell has a first frame and a second frame. The high-current supply module is fixed to the first frame for outputting a high-current voltage, and the power input of the high-current supply module comes from alternating current. The low-current supply module is fixed to the second frame for outputting a low-current voltage, and the power input of the low-current supply module comes from direct current. The outer surface of the high-current supply module and / or the outer surface of the low-current supply module is provided with an insulating material, and the insulating material insulates and isolates the high-current supply module from the low-current supply module.

[0019] In this embodiment, insulating material is applied to the outer surface of at least one of the high-current supply module and the low-current supply module to electrically insulate the module from the low-current supply module, thereby ensuring electrical safety within the power supply device.

[0037] Compared to the prior art, this disclosure proposes a new power supply device, which includes a high-voltage power supply module (or module group) and a low-voltage power supply module (or module group) that are insulated and isolated from each other, for providing high-voltage and low-voltage voltages to electrical devices, respectively. Various embodiments of this power supply device are described below.

[0038] First embodiment

[0039] Figure 1 FIG2 shows an exploded schematic diagram of a power supply device according to a first embodiment of the present disclosure. The power supply device 10 includes a housing 11 , a high-current supply module 12 , a low-current supply module 13 , and an insulating member 110 . Figure 2 A schematic diagram of a housing according to a first embodiment of the present disclosure is shown. A first cavity 111 and a second cavity 112 are provided inside the housing 11. The high-voltage supply module 12 is provided in the first cavity 111 for outputting a high-voltage voltage. A high-voltage supply interface such as a two-hole or three-hole type may be provided on one side surface of the high-voltage supply module 12, which can be connected to a plug of a high-power electrical appliance to output an AC voltage of, for example, 125 volts or 250 volts. The power input of the high-voltage supply module 12 comes from AC power, such as an external mains power supply or a vehicle-mounted generator. The low-voltage supply module 13 is provided in the second cavity 112 for outputting a low-voltage voltage. A low-voltage supply interface such as a USB type may be provided on one side surface of the low-voltage supply module 13, such as, but not limited to, a USB-A interface, a USB-C interface, etc. The low-voltage supply interface can be connected to a cable for charging an electronic device (such as a mobile phone, a tablet computer, a smart watch, etc.), and output a DC voltage such as 5 volts to 36 volts. Most commonly, the weak current interface outputs a DC voltage of approximately 5 volts, which is used to charge personal consumer electronic devices. The weak current module 13 receives power from a DC source, which can be sourced from an onboard energy storage battery. An insulating member 110 is disposed within the housing 11, isolating the strong current module 12 from the weak current module 13.

[0040] The insulating member 110 is disposed between the first cavity 111 and the second cavity 112 to insulate the strong current supply module 12 from the weak current supply module 13. Figure 2 The insulating member 110 divides the interior of the housing 11 into a first cavity 111 and a second cavity 112 .

[0041] Figure 3 Another schematic diagram of an insulating member according to the present disclosure is shown. In this example, the insulating member 110 includes a first insulating member 110 a , which is disposed on an inner wall of a first cavity 111 .

[0042] Figure 42 is another schematic diagram of an insulating member according to the present disclosure. In this example, the insulating member 110 includes a second insulating member 110 b , which is disposed on an inner wall of the second cavity 112 .

[0043] The insulating member 110 may include plastic, rubber, ceramic, or other electrically insulating materials. In other examples, a first insulating member 110a may be disposed on the inner wall of the first cavity 111, and a second insulating member 110b may be disposed on the inner wall of the second cavity 112, wherein the first insulating member 110a and the second insulating member 110b may be made of the same or different materials.

[0044] In one example, the insulating member 110 can be integrally formed with the housing 11. In another example, the insulating member 110 can be a separate component that is detachably disposed within the housing 11. The insulating member 110 can be detachably disposed at different positions within the housing 11 to change the shapes of the first cavity 111 and the second cavity 112, for example, to flexibly accommodate different arrangements of the high-voltage and low-voltage power supply modules.

[0045] Figure 5 The figure shows an internal schematic diagram of a power supply device according to the first embodiment of the present disclosure. The high-voltage power supply module 12 and the low-voltage power supply module 13 are disposed in corresponding cavities, and their fixing methods include, but are not limited to, fastener connection, welding, bonding, riveting, or part clamping. Optionally, the height H1 of the insulating member 110 within the housing 11 is greater than the height H2 of the low-voltage power supply module 13 within the second cavity 112. This has the advantage of increasing the electrical clearance and creepage distance between the high-voltage power supply module 12 and the low-voltage power supply module 13.

[0046] Reference Figure 1 The power supply device 10 further includes a cover 14 fixed to the housing 11, which is used to cover the first cavity 111 and the second cavity 112. The cable used to connect the power supply device 10 to an external DC or AC power source can pass through the surface of the cover 14 or pass through the gap between the cover 14 and the housing 11.

[0047] Figure 6 FIG1 shows another schematic diagram of the power supply device according to the first embodiment of the present disclosure, in which the components in the power supply device housing 11 have been assembled. Figure 6 The power supply device 10 further includes a panel 31 fixed to the housing 11, which includes openings to expose the high-power supply interface 121 of the high-power supply module 12 and the low-power supply interface 131 of the low-power supply module 13. After assembly, the power supply device 10 is suitable for installation in a mounting hole 41 on an installation interface 40 (such as a wall panel).

[0048] In this embodiment, the high-current supply module 12 and the low-current supply module 13 are electrically insulated by arranging an insulating member 110 in the power supply device 10. The provision of the insulating member 110 increases the creepage distance between the high-current supply module 12 and the low-current supply module 13, so that the actual distance between the high-current supply module 12 and the low-current supply module 13 can be reduced as much as possible while considering electrical safety. This technical solution reduces the occupied space of the power supply device 10, which is particularly necessary in the application scenario of RVs. In addition, since the power inputs of the high-current supply module 12 and the low-current supply module 13 come from external AC power and external DC power, no additional voltage conversion circuit (such as an AC voltage to DC voltage converter) is required inside the power supply device 10, so the power supply device 10 is relatively small.

[0049] Of course, the power supply device 10 of this embodiment can be applied to RVs, and can also be applied to other applicable scenarios such as homes and office environments.

[0050] Second embodiment

[0051] Figure 7 A schematic exploded view of a power supply device according to a second embodiment of the present disclosure is shown. Figure 8 A schematic diagram of a partially assembled power supply device according to a second embodiment of the present disclosure is shown. The power supply device 20 includes a housing 21, a high-voltage power supply module 22, and a low-voltage power supply module 23. The housing 21 has a first frame 210 and a second frame 211. The high-voltage power supply module 22 is fixed to the first frame 210 for outputting high-voltage voltage. A high-voltage power supply interface 221 such as a two-hole or three-hole type can be provided on one side surface of the high-voltage power supply module 22. The high-voltage power supply interface 221 can be connected to the plug of a high-power electrical appliance to output an AC voltage of, for example, 125 volts or 250 volts. The power input of the high-voltage power supply module 22 comes from AC power, for example, from an external mains supply or a vehicle-mounted generator. The low-voltage power supply module 23 is fixed to the second frame 211 for outputting low-voltage voltage. A low-voltage power supply interface 231 such as a USB type can be provided on one side surface of the low-voltage power supply module 23, for example, but not limited to a USB-A interface, a USB-C interface, etc. The weak current supply interface 231 can be connected to a cable for charging an electronic device (such as a mobile phone, a tablet computer, a smart watch, etc.), and then outputs a DC voltage such as 5 volts to 36 volts. Most commonly, the weak current supply interface 231 outputs a DC voltage of about 5 volts, which is applied to the charging of personal consumer electronic devices. The power input for the weak current supply module 23 comes from direct current, which can be derived from an on-board energy storage battery. The outer surface of the strong current supply module 22 and / or the outer surface of the weak current supply module 23 are provided with an insulating material, and the insulating material insulates and isolates the strong current supply module 22 from the weak current supply module 23.

[0052] The insulating material may be plastic, inorganic insulating material, organic insulating material, or mixed insulating material. Figure 7 In this embodiment, the outer surface of the strong current module 22 is provided with a first insulating material 24a and the outer surface of the weak current module 23 is provided with a second insulating material 24b. The insulating materials 24a and 24b on the outer surface of the modules wrap the circuit therein. The first insulating material 24a and the second insulating material 24b can be the same or different materials. The shape of the housing 21 is not limited to Figure 7 The example given has only a frame structure, which may also be similar to Figure 1 An example of a housing cavity is given. In another example, the outer surface of the strong current module 22 is provided with an insulating material 24a, and the outer surface of the weak current module 23 is not provided with an insulating material 24b. The weak current module 23 is placed in a shell, and its electrical insulation from the outside is achieved by the insulating material of the shell. In another example, the outer surface of the weak current module 23 is provided with an insulating material 24b, and the outer surface of the strong current module 22 is not provided with an insulating material 24a. The strong current module 22 is placed in a shell, and its electrical insulation from the outside is achieved by the insulating material of the shell.

[0053] The high-current supply module 22 can be detachably fixed to the first frame 210 , and the low-current supply module 23 can be detachably fixed to the second frame 211 . The fixing methods include but are not limited to fastener connection, welding, bonding, riveting or part clamping.

[0054] Figure 9 FIG2 shows another schematic diagram of a power supply device according to a second embodiment of the present disclosure, in which the components on the power supply device housing 21 have been assembled. Figure 9 The power supply device 20 further includes a panel 51 fixed to the housing 21, which includes openings to expose the high-voltage power supply interface 221 of the high-voltage power supply module 22 and the low-voltage power supply interface 231 of the low-voltage power supply module 23. After assembly, the power supply device 20 is suitable for installation in a mounting hole 61 on an installation interface 60 (such as a wall panel).

[0055] In this embodiment, insulating material is provided on the outer surface of at least one of the strong-current supply module 22 and the weak-current supply module 23, so that the strong-current supply module 22 is electrically insulated from the weak-current supply module 23. The provision of the insulating material ensures electrical safety within the power supply device 20, increases the creepage distance between the strong-current supply module 22 and the weak-current supply module 23, and avoids short circuits. In addition, since the power inputs of the strong-current supply module 22 and the weak-current supply module 23 come from external AC power and external DC power, the power supply device 20 does not require additional space to accommodate a voltage conversion circuit (such as an AC voltage to DC voltage converter). The power supply device 20 with a smaller volume will show obvious advantages in the application scenario of a motorhome.

[0056] Of course, the power supply device 20 of this embodiment can be applied to RVs, and can also be applied to other applicable scenarios such as homes and office environments.

[0057] Although the present disclosure has been described with reference to specific examples, which are intended to be illustrative only and not limiting of the present disclosure, it is obvious to those skilled in the art that changes, additions, or deletions may be made to the disclosed embodiments without departing from the spirit and scope of the present disclosure.
