Abstract

A magnetic power conversion device includes a power plug and an AC-to-DC socket electrically connected to the power plug, wherein an AC-to-DC circuit is provided in the AC-to-DC socket; a plurality of conversion connectors are provided on the surface of the AC-to-DC socket; and a plurality of DC-to-DC converters are also provided, wherein the DC-to-DC converters are provided with connectors, which are detachably connected and arranged in the conversion connectors; and the DC-to-DC converters are also respectively connected with connecting wires for connecting to low-voltage DC electrical equipment. This allows consumers to replace their mobile phones or other electronic devices without having to replace the circuit part (i.e., the socket part) that converts AC to fixed DC, but only needs to replace the cheap DC-to-DC component (i.e., the converter part), thereby reducing consumer costs and improving resource waste.

Description

Technical Field

[0001] The invention relates to a magnetic power conversion device. Background Art

[0002] The battery capacity of modern mobile phones or other electronic devices is getting larger and larger. The traditional fixed 5V charging cannot meet the demand for fast charging, so various fast charging methods have emerged. For example, the well-known QC and PD fast charging methods. However, due to the variability of its output voltage, these two chargers can only output in a single port and cannot be output in parallel.

[0003] Although some charger manufacturers have made multi-port outputs, their chargers actually use multiple sets of conversion circuits inside, which makes the cost high. We all know that the voltage conversion inside the charger is mainly divided into two types: AC to DC circuit and DC to DC circuit. The AC to DC circuit requires a transformer and various high-voltage parts, and its cost is often higher than that of the DC to DC circuit.

[0004] Moreover, due to the incompatibility of communication protocols of different manufacturers, or the incompatibility of communication protocols after product upgrades, the utilization rate of chargers will be greatly reduced, resulting in the need to replace a batch of chargers every time a mobile phone or other electronic device is replaced, which indirectly increases the cost of use for consumers, causes waste of resources and environmental damage.

[0005] On the other hand, traditional power plugs and sockets have fixed directions and small sockets. When the plug is inserted into the socket at an angle, the conductive parts are easily exposed, causing accidental electric shock. The exposed high-voltage electrodes are very inconvenient and unsafe for the elderly and children to use.

[0006] The ordinary magnetic plugs and sockets on the market are easy to use, but because they are magnetic and easily attract metal, they are not suitable for use in high-voltage connection areas. They can only be used on low-voltage equipment ends and cannot be used on AC socket ends. Summary of the invention

[0007] In view of the above situation, in order to solve the problems existing in the above technology, the present invention proposes a magnetic power conversion device, including a power plug and an AC-to-DC socket electrically connected to the power plug, wherein an AC-to-DC circuit is provided in the AC-to-DC socket; a plurality of conversion connectors are provided on the surface of the AC-to-DC socket; and also including a plurality of DC-to-DC converters, wherein the DC-to-DC converters are provided with connectors, which are detachably connected and arranged in the conversion connectors; and the DC-to-DC converters are also respectively connected with connecting wires for connecting to low-voltage DC electrical equipment.

[0008] The direct current refers to a low-voltage direct current within the safe voltage range for human bodies, and the conversion connector is a magnetic conversion connector.

[0009] According to a magnetic power conversion device of the present application, a first magnet is provided in the conversion connection seat, and a second magnet is provided in the connection head. The first magnet and the second magnet attract each other when the connection head is connected to the conversion connection seat.

[0010] According to a magnetic power conversion device of the present application, a connection contact PCB board is provided in the conversion connection socket, a charger PCB board is provided in the connection head, and elastic connection terminals are provided on the charger PCB board. The elastic connection terminals and the connection contacts on the connection contact PCB board are in contact and connected with each other when the connection head is connected and arranged in the conversion connection socket.

[0011] According to a magnetic power conversion device of the present application, a converter in-position detection sensor is provided in the conversion connector, and the top end of the detection rod of the converter in-position detection sensor passes through a circular hole opened on the connection contact PCB board and is located above the connection contact PCB board.

[0012] According to a magnetic power conversion device of the present application, a spring for pushing the detection rod to move up and down is provided at the bottom of the in-position detection sensor of the converter.

[0013] After adopting the technology proposed by the present invention, the magnetic power conversion device according to the embodiment of the present invention has the following beneficial effects.

[0014] 1) By integrating the circuit that converts AC into a fixed DC voltage into the socket, and then transferring the energy to the power-consuming device through the DC-DC circuit, the unchanging part of the charger is fixed, and only the low-cost DC-DC part needs to be replaced each time, which increases versatility. By integrating the high-cost part of converting AC into a fixed DC voltage into the socket, and then using a low-cost converter to convert the fixed DC voltage of the socket into the variable DC voltage output required for fast charging, consumers do not need to replace the AC-to-fixed DC circuit part (i.e. the socket part) every time they replace their mobile phones or other electronic devices, but only need to replace the cheap DC-to-DC component (i.e. the converter part), which reduces consumer costs and improves resource waste.

[0015] 2) At the same time, since the AC is converted into a fixed DC voltage and integrated into the socket, the socket part can be implemented in the form of a multi-port parallel output with a single set of conversion circuits.

[0016] 3) Since the socket outputs a low DC voltage (human safety voltage), it uses a human safety low voltage magnetic attraction method. Even if an accidental touch occurs, it will not cause harm to the human body, making it safe and convenient for consumers to use. It is especially suitable for the elderly and children to avoid the risk of electric shock.

[0017] 4) At the same time, each socket, i.e., the conversion connection socket, has a converter in place detection function. When the converter is not connected, all contacts have no output voltage, which further enhances the safety of use and the prevention of accidental contact with metal conductors; at the same time, the entire conversion socket can achieve zero loss like an ordinary socket when there is no converter in place.

Moreover, in order to make the specification more clear and concise, detailed descriptions of functions and configurations well known in the art will be omitted.

[0024] like Figure 1-5As shown, a magnetic power conversion device includes a power plug 1 and an AC-to-DC socket 2 electrically connected to the power plug 1, wherein the AC-to-DC socket 2 is provided with an AC-to-DC circuit; a plurality of conversion connectors 20 are provided on the surface of the AC-to-DC socket 2; and a plurality of DC-to-DC converters 3 are also included, wherein the DC-to-DC converters 3 are provided with connectors 30, and the connectors 30 are detachably connected and arranged in the conversion connectors 20; and the DC-to-DC converters 3 are also respectively connected with connection lines 4 for connecting to low-voltage DC electrical equipment 40.

[0025] The conversion connection seat 20 is provided with a first magnet 21 , and the connection head 30 is provided with a second magnet 31 . The first magnet 21 and the second magnet 31 are attracted to each other when the connection head 30 is connected to the conversion connection seat 20 .

[0026] The conversion connection seat 20 is provided with a connection contact PCB board 22, the connection head 30 is provided with a charger PCB board 32, and the charger PCB board is provided with elastic connection terminals 321. The elastic connection terminals 321 and the connection contacts on the connection contact PCB board 22 are in contact and connected with each other when the connection head 30 is connected and arranged in the conversion connection seat 20.

[0027] The converter connection base 20 is provided with a converter in-position detection sensor 5 , and the top end of a detection rod 50 of the converter in-position detection sensor 5 passes through a circular hole provided on the connection contact PCB board 22 and is located above the connection contact PCB board 22 .

[0028] A spring 51 is provided at the bottom of the converter in-position detection sensor 5 to push the detection rod 50 to move up and down.

[0029] The method for detecting the converter in position is to place the connector 30 of the DC-to-DC converter 3 into the conversion connector 20 arranged on the surface of the AC-to-DC socket 2, the first magnet 21 arranged in the conversion connector 20 and the second magnet 31 arranged in the connector 30 attract each other, the connector 30 pushes the detection rod 50 of the converter in position detection sensor 5 to move downward, and the converter in position detection sensor 5 detects the signal of the change of motion state and transmits it to the control component in the control board arranged in the AC-to-DC socket 2.

[0030] In this case, the circuit that converts AC to fixed DC voltage is integrated into the socket, and then the energy is transmitted to the power-consuming device through the DC-DC circuit, so that the unchanging part of the charger is fixed, and only the low-cost DC-DC part needs to be replaced each time, which increases versatility. By integrating the high-cost part of converting AC to DC fixed voltage into the socket, and then converting the fixed DC voltage of the socket into the variable DC voltage output required for fast charging through a low-cost converter, consumers do not need to replace the AC-to-fixed DC circuit part (i.e. the socket part) every time they replace their mobile phones or other electronic devices, but only need to replace the cheap DC-to-DC component (i.e. the converter part), which reduces consumer costs and improves resource waste.

[0031] At the same time, since the AC is converted into a fixed DC voltage and integrated into the socket, the socket part can be implemented in the form of a multi-port parallel output with a single set of conversion circuits.

[0032] The socket in this case outputs a DC low voltage (human safety voltage) and uses a human safety low voltage magnetic attraction method. Even if an accidental touch occurs, it will not cause harm to the human body, making it safe and convenient for consumers to use. It is especially suitable for the elderly and children to avoid the risk of electric shock.

[0033] At the same time, each socket, i.e., the conversion connector, has a converter in place detection function. When the converter is not connected, all contacts have no output voltage, which further enhances the safety of use and the prevention of accidental contact of metal conductors.

[0034] At the same time, each socket is equipped with a self-power-off trigger switch. When there is absolutely no converter connected, the entire socket is shut down with no standby loss.

[0035] At the same time, since it is a new type of voltage converter, in order to facilitate popularization, this solution also designs a connecting component 6 for use when going out and a connecting component 7 for use when driving.

[0036] The present invention has been introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.

Of course, the above listed situations are only examples, and the present invention is not limited thereto.
