Active heat dissipation joint and bionic robot including the heat dissipation joint

Abstract

The invention provides an active heat dissipation joint and a bionic robot comprising the heat dissipation joint. The joint includes a joint shell, the joint shell is used to be sleeved on the outside of the heat source, the outer surface of the joint shell has an accommodation groove and a supporting structure on the side of the accommodation groove, and the joint also includes: sleeved on the inner wall of the joint shell The thermoelectric refrigeration unit between the heat source and the thermoelectric refrigeration unit includes a cold end and a hot end, the cold end is configured to be in direct contact with the heat source, and the hot end is in direct contact with the inner surface of the joint shell; the container fixed on the joint shell The uniform temperature heat pipe placed in the groove; the heat dissipation rib member fixed on the outer surface of the joint shell, and the outer surface of the heat dissipation rib member has at least one protruding heat dissipation rib; wherein, the cold end of the thermoelectric refrigeration unit is used To continuously cool the heat source and transfer the heat to the hot end, the hot end transfers the heat to the joint shell, absorbs it through the joint, and dissipates heat through the heat dissipation ribs of the heat dissipation rib member.

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 comprising the heat dissipation joint. Background technique [0002] As the power unit of the robot, the robot power joint is the core unit of the whole system. Humanoid robots simulate human motion patterns such as walking, running, and jumping, and require dynamic joints to have instantaneous high explosive force and high torque density output. The long-term high-load work of the power joint will inevitably generate huge energy, and the installation space of the joint power components is small, the ventilation and heat dissipation conditions are poor, and the heat cannot be dissipated in time, resulting in serious instantaneous heating of the joint power components. If this is the case for a long time, it will affect the service life of the joint dynamic components and the joint, and the extreme working conditions may lead to the...

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
