[0046] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0047] Please refer to Figure 1 , Figure 1 This diagram illustrates the structure of the multi-power control device 10 provided in this embodiment. The multi-power control device 10 includes a control module 101 and multiple power switching modules 102. Each power switching module 102 includes at least two switching units 201, each corresponding to a different output channel L, such as the first output channel L1, the second output channel L2, ..., the (n-1)th output channel L in the diagram. n-1 The nth output channel L n The control module 101 is connected to the control terminals of each switching unit 201.
[0048] Please continue to refer to this. Figure 1 In this embodiment, at least two switching units 201 include target unit 201A.
[0049] The control module 101 is used to send a first control signal to the target unit 201A to drive the target unit 201A to conduct, so as to supply power to the load through the output channel L corresponding to the target unit 201A, namely the first output channel L1 set in the figure.
[0050] It should be noted that the number of target units can be one or more, and the corresponding number of loads requiring power supply can also be one or more. In this case, the control module can send a first control signal to one or more target units to drive each target unit to conduct, thereby supplying power to the loads through the corresponding output channels of each target unit.
[0051] In this embodiment, the target unit, load, and output channel have a one-to-one correspondence, meaning that one target unit supplies power to the load through one output channel. It should be noted that this application does not limit the number of loads, target units, or output channels. Taking output channels as an example, the number n of output channels can be set according to actual needs.
[0052] Based on this, this embodiment can overcome the problem of the lack of a control structure for multi-power switching output in the prior art, and realize fast and accurate multi-power switching output, thereby improving power supply efficiency.
[0053] In this embodiment, please refer to Figure 2 , Figure 2 The diagram shows the structure of the switching unit in this embodiment. Each switching unit 201 includes at least two relays 301, and each relay 301 is connected in series with the load to form an output channel.
[0054] Please Figure 2 Based on, refer to Figure 3 , Figure 3 The diagram shows another structural schematic of the switching unit in this embodiment. In one possible implementation, when the switching unit 201 includes two relays 301, the load that needs to be powered includes two power supply ports, such as a positive terminal and a negative terminal. One end of one relay 301 is connected to the power supply terminal VCC+ to receive a current of a preset power, and the other end is connected to the positive terminal of the load. One end of the other relay 301 is connected to the negative terminal of the load, and the other end is connected to the power supply terminal VCC-. At this time, the two relays 301 are connected in series with the load to form a conductive power supply loop, i.e., the output channel L.
[0055] In this embodiment, please continue to refer to Figure 2 In this embodiment, the output channels L formed by the switching units 201 under each power switching module 102 are connected in parallel.
[0056] Please refer to Figure 4 , Figure 4 The diagram shows the structure of the multi-power control device in this embodiment. In this embodiment, the output channel L may include multiple path types. In one possible implementation, the output channel L formed by each switching unit 201 under each power switching module 102 corresponds to a path type. For example, when the power switching module 102 includes two switching units 201, each power switching module 102 may correspond to two path types. It should be noted that in this embodiment, the path type can be used to characterize different access points of the load.
[0057] Please refer to Figure 5 , Figure 5 This diagram illustrates another structural schematic of the multi-power control device in this embodiment. When each output channel L includes multiple path types, and each output channel L formed by the switching units 201 under each power switching module 102 corresponds to a path type, the relays 301 in each switching unit 201 under the same path type share a single circuit copper busbar 302. Specifically, assuming this embodiment includes two path types, namely path type A and path type B, when each power switching module 102 includes two switching units 201, it corresponds to the two path types.
[0058] Taking path type A as an example, in this application, the relays 301 corresponding to the same type A output channel L under the multi-power control device 10 share a common circuit copper busbar 302. In this embodiment, the circuit copper busbar 302 is composed of multiple copper busbars. Please continue to refer to... Figure 5 This embodiment includes two copper busbars 302. Path type A corresponds to the first copper busbar 3021, the second copper busbar 3022, and the third copper busbar 3023; correspondingly, path type B corresponds to the fourth copper busbar 3024, the fifth copper busbar 3025, and the sixth copper busbar 3026. This embodiment does not limit the connection relationship between the above copper busbars, as long as the conduction of each output channel L can be achieved.
[0059] Please refer to Figure 6 , Figure 6 This diagram shows another structural schematic of the multi-power control device in this embodiment. When each output channel L includes two path types, the multi-power control device 10 in this embodiment also includes two relay modules 103; each relay module 103 corresponds to one path type; the control module 101 is connected to the control terminal of each relay module 103.
[0060] In this embodiment, the control module 101 is also used to send a second control signal to each relay module 103 to drive the corresponding relay module 103 to conduct, so as to supply power to the load through the output channel L corresponding to the preset path type of the target unit 201A.
[0061] Based on this, when the corresponding path type is selected, the control module 101 sends a control signal to the corresponding relay module 103. For example, if path type A or path type B is required, a control signal is sent to the corresponding relay module 103 for path type A or path type B. Similarly, if path type A and path type B are required, a control signal is sent to the corresponding relay module 103 for path type A and path type B to supply power to the load according to the output channel L corresponding to the preset path type.
[0062] Please refer to Figure 7 , Figure 7 This diagram illustrates another structural schematic of the power switching module in this embodiment. The multi-power control device 10 in this embodiment includes multiple power modules 104, each power module 104 corresponding to a power switching module 102. The input terminal of each power module 104 is connected to its corresponding power switching module 102. The output power of each power module 104 is different.
[0063] In another possible implementation, to reduce the structural size of the multi-power control device, this embodiment can also integrate the power module 104 together; please refer to [reference needed]. Figure 8 , Figure 8 This diagram shows another structural schematic of the power switching module in this embodiment. In this embodiment, the multi-power control device 10 includes a power component 105, which is connected to the input terminal of each power switching module 102; the control module 101 is also connected to the control terminal of the power component 105.
[0064] In this embodiment, the power component 105 includes multiple output states, each corresponding to a different output power. The control module 101 is used to send a third control signal to the power component 105, driving the power component 105 to send a current with the corresponding output power to the corresponding power switching module 102.
[0065] Unlike the power module 104 in the previous embodiment, in this embodiment the control module 101 needs to send a corresponding signal to the power component 105 so that the power component 105 outputs the corresponding power.
[0066] Please refer to Figure 9 , Figure 9 Another structural schematic diagram of the multi-power control device is shown. When two output powers are required to supply power to the corresponding loads at the same time, the multi-power control device 10 in this embodiment includes two power switching modules 102 and two power modules 104; each power module 104 is connected to the corresponding power switching module 102.
[0067] In this embodiment, the control module 101 is used to send a first control signal to the corresponding power switching module 102 to drive the target unit 201A under each power switching module 102 to conduct, so as to supply power to the corresponding load through the corresponding first output channel L1 and the fourth output channel L4.
[0068] Among them, the path types of the output channels L corresponding to the target unit 201A under the power switching module 102 are different.
[0069] refer to Figure 10 , Figure 10 Another structural schematic diagram of a multi-power control device is shown. Specifically, when the multi-power control device 10 includes multiple power switching modules 102, each power switching module 102 includes two switching units 201, and each switching unit 201 includes two relays 301, any power switching module 102 includes a first relay 3011, a second relay 3012, a third relay 3013, and a fourth relay 3014.
[0070] In this embodiment, the first relay 3011 and the second relay 3012 are both connected in series with the first load, forming a first series branch. The third relay 3013 and the fourth relay 3014 are both connected in series with the second load, forming a second series branch. The first series branch and the second series branch are connected in parallel.
[0071] In this embodiment, the first load and the second load correspond to different power levels.
[0072] When power is needed to supply the first load, in this embodiment, the control module 101 sends a first control command to the current power switching module 102 to drive the first relay 3011 and the second relay 3012 to turn on, and the third relay 3013 and the fourth relay 3014 to turn off, so that the current I1 of the first preset output power flows into the first relay 3011 and flows out from the second relay 3012, forming an output channel of the first path type to supply power to the first load.
[0073] Similar to the previous embodiment, when power is needed for the second load, the control module 101 sends a second control command to the current power switching module 102 to drive the first relay 3011 and the second relay 3012 to close, and the third relay 3013 and the fourth relay 3014 to close. This causes the current I2 of the second preset output power to flow into the third relay 3013 and out of the fourth relay 3014, forming a second path type output channel to power the second load.
[0074] Similar to the previous embodiment, this application also provides a multi-power control system, including the above-described multi-power control device.
[0075] Based on this, this embodiment provides a multi-power control scheme, which can make up for the lack of a control structure in the prior art that can perform multi-power switching output, and improve power supply efficiency.
[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
