Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a switching power supply device. Background Art

[0002] A switching power supply (SMPS) utilizes modern power electronics to control the on / off timing ratio of a switching transistor to maintain a stable output voltage. In modern electronic devices, switching power supplies often need to handle circuits with different characteristics: high-voltage, high-current, and low-voltage, low-current. For example, in smart homes, devices like security cameras and smoke detectors often fall under the low-voltage category, while air conditioners and water heaters represent typical high-voltage loads. In some cases, both may share the same power system, posing significant challenges to power distribution and management. Inadvertently mixing high-voltage and low-voltage circuits can lead to signal distortion and equipment damage, at best, or even fire, electric shock, and other personal safety hazards. Furthermore, even if high-voltage and low-voltage circuits are correctly distinguished, ensuring a swift and safe switchover to backup power in the event of a primary power failure remains a key challenge.

Furthermore, even products claiming to offer "dual power" often only offer simple switching between two power sources of the same level, lacking effective solutions for intelligent matching and automatic conversion between high-voltage and low-voltage power.

[0025] The following is combined with Figure 1-4 , an embodiment of a switching power supply device of the utility model is further described in detail.

[0026] Example 1

[0027] A switching power supply device, such as Figure 1 、 2 As shown, it includes a mounting base 1, a switching power supply 2 fixed on the mounting base 1, and an expansion circuit 3 located on the left and right sides of the switching power supply 2. The expansion circuits 3 on the left and right sides are each provided with a power paddle switch 4, which is electrically connected to the expansion circuit 3; the switching power supply 2 is provided with a power switching switch 5 for switching between strong current and weak current, which is electrically connected to the switching power supply 2; the switching power supply 2 is also provided with a switching operating mechanism 6; the switching operating mechanism 6 is respectively connected with the power paddle switch 4 and the power switching switch 5 to switch to one of strong current output, weak current output or strong and weak current synchronous output according to usage requirements.

[0028] Specifically, generally, due to different usage scenarios, a general power switch device usually needs to provide multiple circuit outputs, including strong current output, weak current output, strong and weak current output at the same time, etc., and the switching power supply device is generally in automatic mode, so that it can intelligently switch the working mode (strong current mode or weak current mode) according to actual conditions; and when manual operation is required, the power switch 5 can be manually replaced by toggling the power paddle switch 4 and the power switch 5 to complete the output of strong current or weak current; in order to achieve efficient, stable and safe distribution and switching of electric power, the utility model sets a switching operating mechanism 6 on the connected switching power supply 2 and the expansion circuit 3, and uses the switching operating mechanism 6 to automatically complete the opening and closing of the power paddle switch 4 and the power switch 5, so that it can switch to different output modes in real time according to the power of the connected product, thereby achieving efficient utilization and distribution of power.

[0029] In this embodiment, if Figure 3 、 4 As shown, the switching operating mechanism 6 includes an adjusting pendulum plate 61, a push plate 62, a transmission assembly 63 and a driving source 64. The adjusting pendulum plate 61 is rotatably connected to the transmission assembly 63, and one end of the adjusting pendulum plate 61 is in contact with the power switching switch 5; there are at least two push plates 62, one end of the two push plates 62 is transmission-connected to the driving source 64 through the transmission assembly 63, and the other end is provided with a clamping groove 621 at a position corresponding to the power paddle switch 4, and the power paddle switch 4 is clamped in the clamping groove 621; the transmission assembly 63 is rotatably connected to the driving source 64 to drive the adjusting pendulum plate 61 and the push plate 62 to rotate together.

[0030] Specifically, in the process of switching the output mode, the switching operating mechanism 6 drives the transmission assembly 63 through the driving source 64 to drive the push plate 62 and the adjustment swing plate 61 to rotate. At this time, the power paddle switch 4 starts to close or open under the action of the push plate 62. At the same time, the reaction force of the power paddle switch 4 is applied to the push plate 62, so that the push plates 62 on the left and right sides can stop rotating after pushing the power paddle to move to the maximum stroke. Similarly, the power switching switch 5 is synchronously closed or opened under the push of the adjustment swing plate 61, so that it can switch to different output modes; wherein, when the power switching switch 5 is opened, the switching power supply device is switched to a single-channel output, that is, it can only output strong power or weak power. With the action of the power paddle switch 4, it is ensured that the switching power supply device can switch to the corresponding strong power output or weak power output according to the connected power voltage requirement; and when strong power and weak power need to be output at the same time, it is only necessary to close the power switching switch 5 to maintain synchronous output.

[0031] In this embodiment, if Figure 4As shown, the transmission assembly 63 includes a rotating shaft 631, a gear 632, a rack 633 and a bevel gear 635. One end of the rotating shaft 631 is rotatably connected to the adjusting swing plate 61, and the other end is connected to the switching power supply 2 through a bearing seat, and the rotating shaft 631 is vertically arranged between the left and right push plates 62; the gear 632 is sleeved on the rotating shaft 631 corresponding to the position of the push plate 62; the rack 633 is fixedly connected to one side of the left and right push plates 62, respectively, and the rack 633 is rotatably engaged with the gear 632; a group of bevel gears 635 are provided, one of which is mounted on the rotating shaft 631, and the other is sleeved on the output end of the driving source 64, and the two bevel gears 635 are rotatably engaged with each other.

[0032] Specifically, in the process of rotating the adjusting swing plate 61 and the push plate 62, the driving source 64 provides power and transmits it to the adjusting swing plate 61 and the push plate 62 through the transmission assembly 63. The rotating shaft 631 rotates synchronously under the driving action of the driving source 64, and drives the gear 632 located on the rotating shaft 631 to rotate. The two sides of the gear 632 are respectively engaged with the rack 633, and the rack 633 is fixed to one end of the push plate 62. Therefore, when the gear 632 rotates, the rack 633 is driven to drive the push plates 62 on the left and right sides to make a linear reciprocating motion. When the gear 632 rotates clockwise, the left push plate 62 moves backward and pushes the power paddle switch 4 to turn on through the clamping slot 621; the right push plate 62 moves forward and pushes the power paddle switch 4 to turn off through the clamping slot 621, and at the same time, the adjustment plate 61 rotates according to the rotation direction of the gear 632 and pushes the power switching switch 5 to turn on; and when the gear 632 rotates counterclockwise, the push plates 62 on the left and right sides will move in the opposite direction, and the adjustment plate 61 rotates according to the rotation direction of the gear 632 at the same time and pushes the power switching switch 5 to turn off.

[0033] It is worth noting that the driving source 64 in the present invention adopts a reduction motor, and a coupling 634 is connected between the driving source 64 and the rotating shaft 631. The reduction motor is used to control the rotation speed of the rotating shaft 631, thereby controlling the rotation amplitude of the adjustment swing plate 61 and the push plate 62 to achieve the opening and closing of the power paddle switch 4 and the power switching switch 5.

[0034] In this embodiment, a high-frequency pulse transformer 7 for step-down conversion is also included, and the high-frequency pulse transformer 7 is connected in series with the expansion circuits 3 on the left and right sides respectively; a plurality of connection ports for connecting to a power supply are respectively provided on both sides of the expansion circuit 3, and the connection ports are divided into an input port 31 and an output port 32, and both the input port 31 and the output port 32 are connected to a terminal 33.

[0035] Specifically, input port 31 is used to connect to a high-voltage power source. After being converted to low-voltage by a high-frequency pulse transformer 7, the output port 32 outputs high-voltage or low-voltage power. The output ports 32 of the left and right expansion circuits 3 are divided into high-voltage output ports 32 and low-voltage output ports 32 according to the output power. The high-voltage output ports 32 are used to connect devices that require high current and high voltage, such as motors and production equipment commonly used in industry, and household appliances such as washing machines and televisions. The low-voltage output ports 32 are suitable for low-power electronic devices with more moderate voltage and current requirements, such as routers, security cameras, and smart sockets.

[0036] In this embodiment, the switching power supply 2 has a built-in intelligent signal processor, which is connected to the high-frequency pulse transformer 7 via an electrical signal to automatically switch the output of the high-voltage or low-voltage circuit.

[0037] Specifically, the intelligent signal processor can automatically detect the power of the connected product and adjust the voltage output intensity by controlling the power of the connected product by the high-frequency pulse transformer 7. At the same time, when the power of the connected product changes, it automatically switches to an output voltage that matches it, and at the same time cuts off the output voltage of the original mode to ensure that the output port 32 does not output strong electricity and weak electricity at the same time.

[0038] In this embodiment, an electric control box 8 is sleeved on the outer side of the mounting base 1 . A plurality of heat dissipation holes 81 are opened on the surface of the electric control box 8 , and a wiring hole 82 is opened at a position corresponding to the wiring port of the electric control box 8 .

[0039] Specifically, in order to further improve the safety of the switching power supply device, an electric control box 8 is sleeved on the outside of the mounting base 1. On the one hand, the electric control box 8 can play a protective role, and on the other hand, it can also prevent dust and water from entering the switching power supply 2 and the expansion circuit 3 to affect their use. At the same time, the heat dissipation holes 81 opened on the electric control box 8 can quickly dissipate the heat generated by the switching power supply device during operation to improve its working efficiency; and the wiring holes 82 opened on the electric control box 8 are to avoid affecting the wiring effect of the terminal 33.

[0040] Example 2

[0041] Based on the first embodiment, the control method for automatically switching power supply of the switching power supply device in the present invention includes the following steps:

[0042] Initialization settings: The power switch 5 is in the on state. At this time, the initial working mode is the simultaneous output of high power mode and low power mode;

[0043] Power supply detection: The power supply identification and intelligent signal processor periodically scans the voltage, current and other parameters of input port 31 to determine the power supply status of the connected product;

[0044] Mode switching: In automatic mode, when it is detected that the connected product in the current mode is outputting strong electricity, the switching operating mechanism 6 automatically switches the output mode of the expansion circuit 3 and cuts off the output of the original mode at the same time, ensuring that the output port 32 does not output strong and weak electricity at the same time; and can automatically change the output voltage and current in real time according to the power of the connected product;

[0045] Safety monitoring: Real-time monitoring of the safety indicators of each output. If the set threshold is exceeded, the corresponding safety protection measures will be immediately triggered, such as power off or alarm.

[0046] In addition, it is worth mentioning that the switching power supply device of the present invention can also be remotely managed, receiving external commands through the remote monitoring interface, performing operations such as mode switching, status query and troubleshooting, thereby improving management efficiency and flexibility.

[0047] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
