[0043] With reference to Figure 1 and Figure 2 The utility model provides a kind of distributed power supply circuit, for the power supply of multiple electric loads 100, this distributed power supply circuit includes:

[0044] First connection unit 110, first connection unit 110 is used to electrically connect a power supply module 400 and a power load 100;

[0045] The second connection unit 120 is electrically connected to the first connection unit 110, and is used to electrically connect another power consumption load 100 and another power supply module 400. The first connection unit 110 is arranged adjacent to a power consumption load 100, and the second connection unit 120 is arranged adjacent to another power consumption load 100.

[0046] The distributed power supply circuit in the embodiment is used to supply power to multiple power consumption loads 100. The power consumption loads 100 can be various devices, such as industrial devices (e.g., numerical control machine tools, sensor modules), household appliances (e.g., air conditioners, refrigerators), lighting devices (e.g., LED lamps), or distributed sensor nodes, etc. The types of power consumption loads 100 depend on the specific application scenario.

[0047] The distributed power supply circuit includes a first connection unit 110 and a second connection unit 120. The main function of the first connection unit 110 is to distribute the power of the power supply module 400 to the corresponding power consumption load 100. When the power consumption load 100 does not need power, the first connection unit 110 distributes the power of the power supply module 400 to other power consumption loads 100 through electrical connection with the second connection unit 120. The second connection unit 120 has similar functions, which are used to distribute the power of the power supply module 400 to its corresponding power consumption load 100, or to receive power from the first connection unit 110 according to demand and distribute it to other power consumption loads 100.

[0048] The first connection unit 110 and the second connection unit 120 can be implemented by various devices, such as current distributors or distribution circuit boards, to efficiently distribute current. They can also be implemented by intelligent control units, such as microcontrollers (MCU) and current sensors, to assist in intelligent and dynamic adjustment of power distribution.

[0049] The first connection unit 110 is arranged adjacent to a power consumption load 100, and the second connection unit 120 is arranged adjacent to another power consumption load 100. This layout design effectively shortens the distance of power transmission. For example, taking two power consumption loads 100 as an example, labeled as power consumption load A and power consumption load B, the first connection unit 110 is arranged adjacent to power consumption load A, and the second connection unit 120 is arranged adjacent to power consumption load B. By reducing the length of the high-current cable, not only the wiring cost is reduced, but also the power transmission efficiency is optimized.

[0050] To facilitate understanding of the working principle of the embodiment, two power supply modules 400 (labeled as power supply module A and power supply module B) and two power consumption loads 100 (labeled as power consumption load A and power consumption load B) are taken as an example for description.

[0051] In the embodiment, the power supply module A supplies power to the power consuming load A through the first connection unit 110, and the power supply module B supplies power to the power consuming load B through the second connection unit 120. Since the first connection unit 110 and the second connection unit 120 are arranged close to the corresponding power consuming load A and power consuming load B respectively, the length of the high current carrying capacity cable is significantly reduced, thereby effectively reducing the cable use cost and power transmission loss.

[0052] In this mode, since the first connection unit 110 and the second connection unit 120 independently supply power to the respective corresponding power consuming load, and there is no sharing or interaction of power between them, the cable between the first connection unit 110 and the second connection unit 120 has almost no current passing through. In other words, the cable between the first connection unit and the second connection unit only needs to conduct current in very few cases, which greatly reduces the current carrying capacity requirement of this part of the cable, and a lighter and lower cost low current carrying capacity cable can be selected.

[0053] In another working mode, when the power consuming load A is in a dormant or shutdown state, the power of the power supply module A can be distributed to the power consuming load B through the electrical connection between the first connection unit 110 and the second connection unit 120. In this case, the power of the power supply module A is transmitted to the second connection unit 120 via the first connection unit 110, and then further supplied to the power consuming load B by the second connection unit 120. For example, the power supply module A outputs 5V voltage, which is transmitted to the second connection unit 120 through the first connection unit 110, and finally provides the required power to the power consuming load B.

[0054] It should be noted that in this working mode, the current flow between the first connection unit 110 and the second connection unit 120 is only half of the total output current of the power supply module, because the power of the power supply module B and the power of the power supply module A both need to be cooperatively distributed to the power consuming load B. This further reduces the current load requirement of the cable between the connection units, so that even if there is current transmission, the current carrying capacity requirement of the cable is much lower than when supplying power to a single power consuming load.

[0055] In summary, by arranging the first connection unit 110 and the second connection unit 120 close to the respective power consuming load, and optimizing the current transmission path between them, the embodiment effectively reduces the cable cost and weight, while reducing the power transmission loss.

[0056] By arranging the first connection unit 110 and the second connection unit 120 close to the respective power consuming load 100, the length of the high current carrying capacity cable can be significantly reduced, thereby reducing the use cost of the cable. High current carrying capacity cables usually have a large cross-sectional area and are relatively expensive, but the structural design of the utility model avoids the use of high current carrying capacity cables over long distances, optimizing the economy of materials.

[0057] Furthermore, since the cable between the first connecting unit 110 and the second connecting unit 120 carries almost no current, or only carries a low current in very rare cases, a cable with low current carrying capacity can be selected. Low current carrying capacity cables are not only cheaper but also lighter, further reducing the overall weight of the system and improving the portability and ease of installation of the device.

[0058] Furthermore, in another operating mode, even if current needs to be transferred between the first connection unit 110 and the second connection unit 120, this portion of the current is only half of the total output current of the power supply module, significantly reducing the requirements for cable current carrying capacity. This design reduces resource waste and lowers the overall cost of equipment manufacturing and maintenance.

[0059] In some embodiments, the first connection unit 110 and the second connection unit 120 both include a first connection terminal A1 and a second connection terminal A2;

[0060] The first connection terminal A1 is used to electrically connect to the power supply module 400, and the second connection terminal A2 is used to electrically connect to the load. The first connection terminal A1 and the second connection terminal A2 are electrically connected through the first wire 201.

[0061] For details, please refer to [link / reference]. Figure 2 In this embodiment, the first connection terminal A1 is used to electrically connect the power supply module 400 (e.g., a battery, a power source, etc.), and the second connection terminal A2 is used to electrically connect the electrical load 100. Then, the first connection terminal A1 and the second connection terminal A2 are connected by a first wire 201, wherein the first wire 201 is a cable with high current carrying capacity, such as a copper core cable or other highly conductive material.

[0062] In conjunction with the aforementioned embodiments, by shortening the cable length and reducing the requirements for cable current carrying capacity, current carrying capacity is saved, achieving efficient current transmission and optimized cost control. This allows the use of high-current-carrying-capacity cables between the power supply module 400 and the corresponding electrical load 100, ensuring reliable current transmission. Simultaneously, since the power supply module 400 is positioned adjacent to the corresponding electrical load 100, the significantly reduced cable length effectively lowers the cost of using high-current-carrying-capacity cables, further reducing the overall weight of the system.

[0063] In summary, through the rational design of the first connecting terminal A1, the second connecting terminal A2, and the first conductor 201, this embodiment achieves reduced cable costs, lighter system weight, and improved power transmission efficiency while ensuring high current carrying capacity.

[0064] See Figure 1 ,Figure 2 and Figure 3 In the embodiment, the first connecting unit 110 is electrically connected to the second connecting unit 120 by the second connecting wire, and the diameter of the first wire 201 is larger than that of the second connecting wire.

[0065] Specifically, the first connecting unit 110 is electrically connected to the second connecting unit 120 by the second wire 202, and the diameter of the second wire 202 is smaller than that of the first wire 201. The first wire 201 is used to connect the power supply module 400 and the corresponding power load 100, and has high current-carrying capacity, which can ensure reliable transmission of large current; while the second wire 202 is used only for current transmission between the first connecting unit 110 and the second connecting unit 120, and has low current-carrying capacity requirement, so that a low current-carrying capacity cable with smaller diameter can be used, such as a thinner copper core cable or other materials with good conductivity and low cost.

[0066] In the embodiment, since the current transmitted between the first connecting unit 110 and the second connecting unit 120 is only half of the output current of the power supply module 400, even if the second wire 202 with low current-carrying capacity is used, it will not affect the transmission performance of the current or the stability of the power supply. This design, based on reasonable allocation of current-carrying capacity, avoids excessive configuration of high current-carrying capacity cable, effectively saving the cost of cable. In addition, the reduction of the diameter of the second wire 202 further reduces the weight of the overall system, improves the installation convenience and economy of the device.

[0067] In summary, by using the second wire 202 with low current-carrying capacity between the first connecting unit 110 and the second connecting unit 120, the embodiment realizes the saving of cable material, reduces the system cost, and optimizes the overall design and performance of the equipment while ensuring reliable transmission of electrical energy.

[0068] Further, the first connecting unit 110 includes a third connecting terminal A3, and the second connecting unit 120 includes a fourth connecting terminal A4, and the third connecting terminal A3 is electrically connected to the fourth connecting terminal A4 by the second wire 202.

[0069] Specifically, reference can be made to Figure 2 and Figure 3 In the embodiment, the third connecting terminal A3 is arranged on the first connecting unit 110, and the fourth connecting terminal A4 is arranged on the second connecting unit 120. The third connecting terminal A3 is electrically connected to the fourth connecting terminal A4 by the second wire 202, so that the first connecting unit 110 and the second connecting unit 120 are electrically connected. The effect of this design is that when the system enters another working mode, the redistribution of electrical energy can be realized.

[0070] For example, in another working mode, when the electrical load A is in a dormant or shutdown state, the first connection unit 110 transmits the power of the power supply module A to the fourth connection terminal A4 of the second connection unit 120 through the third connection terminal A3 and the second wire 202. At this time, the second connection unit 120 distributes the power of the power supply module A and the power of the power supply module B to the electrical load B through the fourth connection terminal A4. This design ensures efficient use of power, avoids waste of resources, and improves the flexibility of the system.

[0071] It should be noted that the third connection terminal A3 and the fourth connection terminal A4 are also respectively electrically connected with the first wire 201 of the respective connection unit. The first wire 201 is responsible for electrically connecting the power supply module 400 and the electrical load 100, and has high current-carrying capacity to ensure stable transmission of current. Therefore, when the third connection terminal A3 and the fourth connection terminal A4 are connected through the second wire 202, only the requirement of low current-carrying capacity needs to be met, thereby further reducing the cost of the cable.

[0072] In summary, through the setting of the third connection terminal A3 and the fourth connection terminal A4 and the electrical connection of the second wire 202, the electrical connection and redistribution between the first connection unit 110 and the second connection unit 120 are realized. This embodiment realizes the rational allocation of resources on the basis of ensuring stable power supply, reduces the system cost, and improves the working efficiency and flexibility of the system.

[0073] Continuing to refer to Figure 2 and Figure 3 In this embodiment, the first connection unit 110 further includes a fifth connection terminal A5, and the second connection unit 120 includes a sixth connection terminal A6.

[0074] The first connection unit 110 and the second connection unit 120 are alternately arranged in multiple, the fifth connection terminal A5 is electrically connected with the sixth connection terminal A6, and the third connection terminal A3 is electrically connected with the fourth connection terminal A4.

[0075] In this embodiment, the first connection unit 110 further includes a fifth connection terminal A5, and the second connection unit 120 includes a sixth connection terminal A6. The first connection unit 110 and the second connection unit 120 are alternately arranged in multiple, the fifth connection terminal A5 is electrically connected with the sixth connection terminal A6, and the third connection terminal A3 is electrically connected with the fourth connection terminal A4.

[0076] In the embodiment, when the first connection units 110 and the second connection units 120 are alternately arranged in multiple, the first connection unit 110 further includes a fifth connection terminal A5, and the second connection unit 120 includes a sixth connection terminal A6. In this way, the first connection units 110 and the second connection units 120 are annularly distributed in multiple alternately arranged manner. In the annular distribution, the third connection terminal A3 is electrically connected to the fourth connection terminal A4 through the second wire 202, and the fifth connection terminal A5 is electrically connected to the sixth connection terminal A6 through the second wire 202.

[0077] In this way, the series connection between the first connection units 110 and the second connection units 120 arranged in multiple alternately is realized, and a complete annular topology is formed. In the annular topology, the electrical energy can be distributed and transmitted between all the connection units through the second wire 202. The annular topology has the advantage that the annular structure allows dynamic distribution of electrical energy between the power supply modules 400 and the electrical loads 100, improving the reliability and utilization of the system. Even if some part of the connection units or the wire fails, the annular topology can still transmit electrical energy through other paths, ensuring the continuous operation of the system.

[0078] At the same time, since the second wire 202 in the annular topology only needs to meet the low current capacity requirement, a small diameter and low cost cable can be used, further reducing the overall cost of the system. And the annular distribution of the first connection units 110 and the second connection units 120 makes the system layout more compact, which helps the miniaturization and modular design of the equipment.

[0079] In summary, through the alternating annular distribution of the first connection units 110 and the second connection units 120, and through the electrical connection of the third connection terminal A3, the fourth connection terminal A4, and the fifth connection terminal A5, the sixth connection terminal A6, the embodiment realizes efficient electrical energy transmission and flexible system topology, while ensuring the reliability of the system, reducing the cost and improving the overall performance.

[0080] In some embodiments, the sum of the number of the first connection units 110 and the second connection units 120 is equal to the number of the electrical loads 100.

[0081] Specifically, in one embodiment, the number of the first connection units 110, the number of the second connection units 120 is an odd number of connection modules, and the number of the electrical loads 100 is an odd number of electrical loads 100.

[0082] The sum of the number of the first connection units 110 and the second connection units 120 is three, and the number of the electrical loads 100 is three.

[0083] Or, the sum of the number of the first connection units 110 and the second connection units 120 is five, and the number of the electric loads 100 is five.

[0084] Or, the sum of the number of the first connection units 110 and the second connection units 120 is seven, and the number of the electric loads 100 is seven.

[0085] In another embodiment, the number of the first connection units 110 and the number of the second connection units 120 are even, and the number of the electric loads 100 is even. For details, please refer to Figure 4 .

[0086] In this embodiment, the sum of the number of the first connection units 110 and the second connection units 120 is two, and the number of the electric loads 100 is two.

[0089] The sum of the number of the first connection units 110 and the second connection units 120 is eight, and the number of the electric loads 100 is eight.

[0090] In the above embodiments, the setting of multiple first connection units 110 and multiple second connection units 120 is supported. When one of the power supply modules 400 stops working and cannot supply power to the corresponding load, the adjacent connection units can transfer half of the power of the respective power supply modules 400 to the load that needs power supply through the third connection terminal A3 and the fourth connection terminal A4, or through the fifth connection terminal A5 and the sixth connection terminal A6. In this way, the continuity of power supply can be ensured, and at the same time, since the current-carrying capacity of the second wire 202 only needs to meet half of the power of the power supply module 400, the requirement for the cable specification is further reduced, and the overall cost of the system is saved.

[0091] In summary, this embodiment realizes efficient use of resources, reduces manufacturing and maintenance costs, while ensuring system flexibility and power supply stability by reasonably allocating the number ratio of connection units and electric loads 100.
