Description
Technical Field
[0001] The utility model relates to the technical field of robot liquid cooling equipment, in particular to a liquid cooling circuit for a humanoid robot. Background Technique
[0002] A humanoid robot is a robot designed to imitate the human body structure and behavior, with human-like limbs and a head, and is capable of performing human-like actions and interactions;
[0003] The joints of a humanoid robot are mainly driven by motors. The rotational torque generated by the motors drives the joints to move, enabling various actions of the robot. When a humanoid robot drives its joints through motors, since the motors generate a certain amount of heat during operation, especially when the robot's limbs perform operations with a certain load, the load on the motors will increase, resulting in an increase in the heat generated by the motors during operation. Generally, the motors use the robot's own shell and structure for heat dissipation, and some motors are additionally provided with cooling fans to enhance the heat dissipation effect. However, due to the complex air duct structure inside the motors, the airflow generated by the fans cannot effectively flow through the heat-generating parts of the motors, thus affecting the heat dissipation effect. Therefore, an effective heat dissipation effect cannot be provided for the motors in a high-load state. Content of the Utility Model
[0004] The purpose of the utility model is to provide a liquid cooling circuit for a humanoid robot, which can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A liquid cooling circuit for a humanoid robot includes a circulation tank, multiple joint motors, and two multi-way connectors; the coolant channels inside the housings of the multiple joint motors are respectively connected to the two multi-way connectors through double-loop pipes. A plurality of heat sinks are fixedly installed on the outside of the circulation tank. A plurality of heat conduction rings are arranged inside the circulation tank, and the plurality of heat conduction rings are fixedly connected through two first heat conduction pipes. A circulation pump is fixedly installed on one side of the top of the circulation tank, and a heat dissipation motor is fixedly installed at the bottom of the circulation tank. The circulation pump and the heat dissipation motor are respectively electrically connected to an external main controller through connection wires. A first flow guide cover is also fixedly installed at the bottom of the circulation tank inside the heat dissipation motor.
[0007] As a further preferred solution of the utility model, the circulation tank stores coolant.
[0008] As a further preferred embodiment of the present utility model, a liquid supplement end cover is movably installed at the center position of the top of the circulation tank. The circulation tank on one side of the liquid supplement end cover is fixedly installed with a liquid outlet end and a liquid inlet end respectively. A suction pipe is fixedly installed at the bottom of the liquid outlet end. The suction pipe is placed inside the circulation tank, and the top of the liquid outlet end is communicated with the input end of one of the multi-way joints through a pipeline. The top of the liquid inlet end is connected to the output end of the circulation pump through a pipeline, and the input end of the circulation pump is connected to the output end of the other multi-way joint. Through the setting of the circulation pump, the liquid supplement end cover, the liquid outlet end, the multi-way joint and the double-way circulation pipe, the circulation of the coolant can be carried out for multiple joint motors.
[0009] As a further preferred embodiment of the present utility model, two connecting pipes are fixedly installed inside the heat conduction ring, and one ends of the two connecting pipes are respectively fixedly connected to the corresponding first heat conduction pipes. The tops of the two first heat conduction pipes respectively pass through the circulation tank and extend to the top of the circulation tank.
[0010] As a further preferred embodiment of the present utility model, the tops of the two first heat conduction pipes are respectively fixedly connected to second heat conduction pipes. The second heat conduction pipes are in an inverted L-shaped structure, and the vertical parts of the second heat conduction pipes are fixedly connected to the corresponding heat dissipation fins. By arranging multiple heat conduction rings inside the circulation tank and connecting the multiple heat conduction rings through two first heat conduction pipes, the heat conduction effect of the coolant at the center position inside the circulation tank can be improved.
[0011] As a further preferred embodiment of the present utility model, a protective cover is arranged outside the heat dissipation motor. A protective net is fixedly connected between the heat dissipation motor and the protective cover. A second air guide cover is fixedly installed at the top of the protective cover. An air outlet channel is formed between the second air guide cover and the first air guide cover. By installing the heat dissipation motor at the bottom of the circulation tank and with the cooperation of the second air guide cover and the first air guide cover, the multiple heat dissipation fins outside the circulation tank can be accelerated in heat dissipation, and the integrity of the overall structure of the circulation tank can improve the heat dissipation effect at the same time.
[0012] Compared with the prior art, the present utility model has the following beneficial effects:
[0013] For the liquid cooling circuit of a humanoid robot described in the present utility model, by circulating the coolant in the cooling channels of the outer shells of multiple joint motors in cooperation with multi-way joints, double-way circulation pipes, a circulation tank and a circulation pump, the temperature of each joint motor can be effectively reduced.

[0023] As Figures 1 - 5As shown, the coolant is stored in the circulation tank 1. A liquid replenishment end cover 10 is movably installed at the center of the top of the circulation tank 1. The circulation tank 1 on one side of the liquid replenishment end cover 10 is fixedly installed with a liquid outlet end 11 and a liquid inlet end 13 respectively. A suction pipe 12 is fixedly installed at the bottom of the liquid outlet end 11. The suction pipe 12 is placed in the circulation tank 1, and the top of the liquid outlet end 11 is communicated with the input end of one of the multi-way connectors 3 through a pipeline. The top of the liquid inlet end 13 is connected to the output end of the circulation pump 8 through a pipeline, and the input end of the circulation pump 8 is connected to the output end of the other multi-way connector 3. Through the settings of the circulation pump 8, the liquid replenishment end cover 10, the liquid outlet end 11, the multi-way connector 3, and the double-way circulation pipe 4, the coolant can be circulated for multiple joint motors 2. Two connecting pipes 14 are fixedly installed inside the heat conduction ring 6, and one ends of the two connecting pipes 14 are respectively fixedly connected to the corresponding first heat conduction pipes 7. The tops of the two first heat conduction pipes 7 respectively pass through the circulation tank 1 and extend to the top of the circulation tank 1. The tops of the two first heat conduction pipes 7 are respectively fixedly connected to second heat conduction pipes 15. The second heat conduction pipes 15 are in an inverted L-shaped structure, and the vertical parts of the second heat conduction pipes 15 are fixedly connected to the corresponding heat dissipation fins 5. By arranging a plurality of heat conduction rings 6 in the circulation tank 1 and connecting the plurality of heat conduction rings 6 through two first heat conduction pipes 7, the heat dissipation effect of the coolant at the central position in the circulation tank 1 can be improved;

Meanwhile, the heat dissipation motor 9 is started, and the wind blown by the heat dissipation motor 9 blows directly through the channel between the first air guide cover 18 and the second air guide cover 19 to the multiple heat dissipation fins 5, thereby quickly dissipating the heat of the multiple heat dissipation fins 5 and the two second heat conducting pipes 15. As a result, the heat dissipation effect of the coolant can be improved, and the operating temperature of each joint motor 2 can be ensured.
