Active heat dissipation joint and bionic robot comprising same

Abstract

The invention provides an active heat dissipation joint and a bionic robot comprising the same. The joint comprises a joint shell, a thermoelectric refrigeration unit, a uniform-temperature heat pipeand a heat dissipation rib component; the joint shell is used for being arranged outside a heating source in a sleeving mode, and the outer side face of the joint shell is provided with a accommodating groove and a supporting mechanism arranged on the side portion of the containing groove; the thermoelectric refrigeration unit is arranged between the inner wall of the joint shell and the heating source in a sleeving mode, and the thermoelectric refrigeration unit is provided with a cold end and a hot end, wherein the cold end is configured to be in direct contact with the heating source, and the hot end is in direct contact with the inner side face of the joint shell; the uniform-temperature heat pipe is fixed in the accommodating groove in the joint shell; and the heat dissipation rib component is fixed to the outer side face of the joint shell, and at least one protruding heat dissipation rib is arranged on the outer side face of the heat dissipation rib component. According to the joint, the cold end of the thermoelectric refrigeration unit is used for continuously cooling the heating source and transferring heat to the hot end, the hot end transfers the heat to the joint shell,and then the heat dissipation is carried out through joint absorption and the heat dissipation ribs of the heat dissipation rib component.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to an active heat dissipation joint and a bionic robot including the heat dissipation joint. Background technique [0002] As the power unit of the robot, the robot dynamic joint is the core unit of the whole system. Humanoid robots simulate human walking, running, jumping and other movement patterns, requiring dynamic joints to have instantaneous high explosive force and high torque density output. Long-term high-load operation of the dynamic joint will inevitably generate huge energy, and the installation space of the joint dynamic components is small, the ventilation and heat dissipation conditions are poor, and the heat cannot be dissipated in time, resulting in severe instantaneous heating of the joint dynamic components. If this happens for a long time, it will affect the service life of the joint dynamic components and joints, and extreme working conditions may lead to irreversi...

Problems solved by technology

However, for some high-end robots that have high requirements for light weight and miniaturization, the existing power joint heat dissipation methods can no longer meet the needs

[0005] There are also a few bionic robots that add an additional cooling system outside the power joint, such as a cooling fan and a cooling cavity, but the cooling fan needs a separate motor to provide power, and the cooling cavity also needs to be powered. The motor is cooled, so the cooling effect is not significant
