Problems solved by technology
[0003] However, the structure of the door opening and closing mechanism of the robot in the prior art is complex. If the door encounters resistance, it will cause fatigue damage to the driving parts that drive the opening and closing of the door, and when the door is opened, the door occupies a large amount of external space.

The invention relates to the technical field of robots, and particularly discloses a door opening and closing mechanism and a robot. According to the door opening and closing mechanism, a door is rotatably mounted on a robot bin through at least two linkage units at different positions, and the at least two linkage units act around at least two staggered rotating shafts respectively, so that the door can adapt to special-shaped shells of different robots to move smoothly when opened or closed; and the door can be opened by a large angle, cannot collide with a close object when opened and cannot occupy a large external space after being completely opened, so that butt joint of the robot and other devices is facilitated, and the structure of the robot is more compact. Besides, a damping protection assembly is connected between the output end of a driving unit and one linkage unit, and when the door is hindered by transmission, the output end of the driving unit is separated from the corresponding linkage unit, the driving unit is prevented from being overheated due to fatigue after being hindered, and therefore the driving unit is effectively protected against strain.
Description
technical field [0001] The invention relates to the technical field of robots, in particular to a door opening and closing mechanism and a robot. Background technique [0002] With the development of logistics and transportation technology in the direction of intelligence and automation, robots are gradually replacing the tasks of manual delivery of goods. Especially for public places such as hotels or office buildings, using robots for express delivery, takeaway or goods transportation can not only reduce labor intensity, Save a lot of labor costs, improve transportation efficiency, and improve the safety of item transportation. [0003] However, the door opening and closing mechanism of the robot in the prior art is complex, and if the door encounters resistance, fatigue damage will be caused to the driving member that drives the door to open and close, and when the door is opened, the door occupies a large external space. SUMMARY OF THE INVENTION [0004] The purpose o...
