Description

Technical Field

[0001] This utility model relates to the field of power supply circuit technology, specifically to a dual-power automatic switching power supply circuit for a humanoid robot. Background Technology

[0002] Robots are a common term for automated machines, which include all machines that mimic human behavior or thought, as well as those that mimic other living beings (such as robotic dogs and robotic cats). In a narrower sense, there are many classifications and controversies surrounding the definition of robots, and some computer programs are even referred to as robots. In modern industry, a robot refers to an artificial machine device capable of automatically performing tasks to replace or assist human work. Ideal, highly realistic robots are the product of advanced integrated cybernetics, mechatronics, computer science and artificial intelligence, materials science, and bionics; the scientific community is currently researching and developing in this direction. The most common types of robots are humanoid robots, animal-shaped robots, and engineered robotic robots.

[0003] Existing humanoid robots, due to their mobility, generally use rechargeable batteries as their power source. Rechargeable batteries offer the following advantages:

[0004] Lightweight and portable, rechargeable batteries are lightweight and easy to remove and transport. They are usually made of high-strength engineering plastics or metal shells, which are drop-resistant, shock-resistant and fire-resistant, ensuring safe use in various environments.

[0005] High energy density rechargeable batteries typically use high energy density lithium-ion batteries, which can store more electrical energy in a smaller volume, providing better endurance for humanoid robots;

[0006] High safety: To ensure the safe use of rechargeable batteries, they are generally equipped with advanced battery management systems and safety protection measures, which can effectively avoid problems such as overcharging, over-discharging, and short circuits. These systems can also monitor the battery status and extend the battery life.

[0007] However, existing mobile humanoid robots typically use a single rechargeable battery, meaning they rely on only one power source. When this battery is depleted, it must be recharged at a charging facility or manually removed and replaced with a fully charged one. This approach requires the robot to stop operating whenever the battery is depleted, waiting for a charged battery to be inserted before resuming normal operation. This disrupts the robot's continuous operation, and the need to shut down and restart the robot each time a battery is replaced leads to a poor user experience. Utility Model Content

[0008] To address the problems in existing technologies, this utility model provides a dual-power automatic switching power supply circuit for humanoid robots. By incorporating a main power supply, a secondary power supply, a power management circuit, and a charging circuit that work in concert, the circuit enables uninterrupted power supply to the humanoid robot. When the main power supply is depleted, it automatically switches to the secondary power supply, while simultaneously reminding the user to charge the main power supply or switch to the fully charged backup power supply. This ensures that the continuous operation of the humanoid robot is not affected, significantly improving the user experience and solving the problem that existing humanoid robots typically use single-cell rechargeable batteries, requiring users to stop working when switching batteries, resulting in a poor user experience.

[0009] This utility model provides a dual-power automatic switching power supply circuit for a humanoid robot, including a main power supply, a secondary power supply, a power supply management circuit, and a charging circuit.

The output terminal of the main power supply is also connected to the input terminal of the charging circuit. The output terminal of the charging circuit is connected to the secondary power supply for charging. The power supply management circuit is also connected to the charging circuit for control. When the main power supply is low on power, the power supply management circuit can automatically switch to the secondary power supply for power supply, and at the same time send a low power warning to the main control circuit board of the humanoid robot.

[0010] This utility model is further improved by including a power management chip U1, capacitors C11, C12, C13, and C20 in the power supply management circuit. The power management chip U1 has 48 pins.

The 24th pin of the power management chip U1 is connected to the main control circuit board of the humanoid robot for power supply. The other ends of capacitors C11, C12, C13, and C20 are grounded.

[0011] This utility model is further improved by including a voltage regulator chip U2, a resistor R6, a diode D1, a fuse resistor F3, and an inductor L2 in the charging circuit. The voltage regulator chip U2 has 8 pins. The 8th pin of the voltage regulator chip U2 is connected to one end of the fuse resistor F3, and the other end of the fuse resistor F3 is connected to the output terminal of the main power supply. The 1st pin of the voltage regulator chip U2 is connected to the negative terminal of the diode D1, and the positive terminal of the diode D1 is connected to one end of the resistor R6. The other end of the resistor R6 is connected to the 26th pin of the power management chip U1. The 6th pin of the voltage regulator chip U2 is connected to one end of the inductor L2, and the other end of the inductor L2 is connected to the input terminal of the auxiliary power supply.

[0012] In a further improvement to this invention, the charging circuit is further provided with capacitors C16, C27, C28, and C29. One end of capacitor C16 is connected to the input terminal of the auxiliary power supply, one end of capacitor C27, and the other end of inductor L2. One end of capacitor C28 is connected to the output terminal of the main power supply and one end of capacitor C29. The other ends of capacitors C16, C27, C28, and C29 are grounded.

[0013] This utility model is further improved, and the power management chip U1 is model N32G435x8 / xB.

[0014] This utility model is further improved, and the voltage regulator chip U2 is model YSP301-100.

[0015] In a further improvement, both the main power supply and the auxiliary power supply are rechargeable lithium-ion batteries.

[0016] Compared with the prior art, the beneficial effects of this utility model are: it provides a dual-power automatic switching power supply circuit for humanoid robots. By setting up a main power supply, a secondary power supply, a power supply management circuit, and a charging circuit that cooperate with each other in the dual-power automatic switching power supply circuit of the humanoid robot, the power supply management circuit can automatically switch to the secondary power supply when the main power supply is low on power. At the same time, it sends a low power warning to the main control circuit board of the humanoid robot, which can realize uninterrupted power supply to the humanoid robot. When the main power supply of the humanoid robot is depleted, it can automatically switch to the secondary power supply to operate, and remind the user to charge the main power supply or switch to the backup fully charged main power supply, ensuring that the continuous working state of the humanoid robot is not affected. This greatly improves the user experience and solves the problem that the rechargeable batteries of humanoid robots in the prior art are generally powered by a single battery, and switching batteries requires stopping the operation, resulting in a poor user experience.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1-3 As shown, this utility model provides a dual-power automatic switching power supply circuit for a humanoid robot, including a main power supply, a secondary power supply, a power supply management circuit, and a charging circuit. The output terminals of the main power supply and the secondary power supply are connected to the input terminal of the power supply management circuit. The output terminal of the power supply management circuit can be connected to the main control circuit board of the humanoid robot. The output terminal of the main power supply is also connected to the input terminal of the charging circuit, and the output terminal of the charging circuit is connected to the secondary power supply for charging. The power supply management circuit is also connected to the charging circuit for control. Both the main power supply and the secondary power supply are rechargeable lithium-ion batteries. In this embodiment, the power supply management circuit can automatically switch to the secondary power supply when the main power supply is low on power, and simultaneously send a low main power supply warning to the main control circuit board of the humanoid robot. When the main power supply voltage drops below a certain threshold, the humanoid robot's main control circuit board instructs the power supply management circuit to switch to the auxiliary power supply. Simultaneously, it prompts the user to remove the main power supply when its battery is depleted and to place another fully charged main power supply into the humanoid robot, or to recharge the main power supply. At this point, the main control circuit board again instructs the power supply management circuit to switch back to the main power supply. The backup auxiliary power supply only needs sufficient power to replace the main power supply. When the auxiliary power supply's battery level drops below a set threshold, the main power supply charges the auxiliary power supply through the charging circuit, ensuring sufficient power for the next battery replacement. This enables uninterrupted power supply to the humanoid robot. It automatically switches to the auxiliary power supply when the main power supply is depleted, while simultaneously reminding the user to charge the main power supply or switch to the backup fully charged main power supply, ensuring continuous operation of the humanoid robot and significantly improving the user experience.

Power management chip U1 is model N32G435x8 / xB and has 48 pins. Pin 1 of power management chip U1 is connected to one end of capacitors C11, C12, and C13, and the output terminal of the main power supply. Pin 36 of power management chip U1 is connected to one end of capacitor C20 and the output terminal of the auxiliary power supply. Pin 26 of power management chip U1 is connected to the charging circuit control, and pin 24 of power management chip U1 is connected to the power supply of the humanoid robot's main control circuit board. The other ends of capacitors C11, C12, C13, and C20 are grounded. In this embodiment, the power supply management circuit automatically switches to the auxiliary power supply when the main power supply is insufficient, based on instructions from the humanoid robot's main control circuit board, and simultaneously sends a low main power supply warning to the humanoid robot's main control circuit board.

[0026] like Figure 3 As shown, the charging circuit includes a voltage regulator chip U2, a resistor R6, a diode D1, a fuse resistor F3, and an inductor L2. The voltage regulator chip U2 is a YSP301-100 with 8 pins. Pin 8 of U2 is connected to one end of the fuse resistor F3, and the other end of F3 is connected to the output of the main power supply. Pin 1 of U2 is connected to the cathode of diode D1, and the anode of diode D1 is connected to one end of resistor R6. The other end of resistor R6 is connected to pin 26 of the power management chip U1. The voltage regulator chip U2's pin 6 is connected to one end of inductor L2, and the other end of inductor L2 is connected to the input terminal of the auxiliary power supply. The charging circuit also includes capacitors C16, C27, C28, and C29. One end of capacitor C16 is connected to the input terminal of the auxiliary power supply, one end of capacitor C27, and the other end of inductor L2. One end of capacitor C28 is connected to the output terminal of the main power supply and one end of capacitor C29. The other ends of capacitors C16, C27, C28, and C29 are grounded. In this embodiment, the charging circuit is used to charge the auxiliary power supply when the auxiliary power supply's battery level is below a set threshold, allowing the main power supply to charge the auxiliary power supply through the charging circuit.

[0027] As can be seen from the above, this utility model provides a dual-power automatic switching power supply circuit for humanoid robots. By setting up a main power supply, a secondary power supply, a power supply management circuit, and a charging circuit that cooperate with each other in the dual-power automatic switching power supply circuit of the humanoid robot, the power supply management circuit can automatically switch to the secondary power supply when the main power supply is low on power.
