Problems solved by technology

When crossing obstacles, the spring needs to help overcome obstacles and buffer them. However, the gravity of the body of the sweeping robot overcomes the elastic force of the spring. When crossing obstacles, the spring can no longer provide effective buffering for the driving wheels, and the inertia of the robot itself is rigidly eliminated. , the robot will have obvious impact and vibration, and the ability to overcome obstacles is relatively poor

Abstract

The invention discloses a drive wheel structure and a cleaning device. The drive wheel structure comprises a support, a drive wheel, a lifting device, a swing guide rail, a first elastic part and a second elastic part and is characterized in that one end of the lifting device is rotatably connected with the support, the second elastic part is arranged at one ends of the support and the lifting device, the other end of the lifting device is arranged at the swing guide rail, the second elastic part provides acting force allowing the lifting device to swing on the swing guide rail along the advancing direction of the drive wheel, the drive wheel comprises a support part, the first elastic part is abutted against a position between one ends of the support part and the lifting device, the drivewheel can telescope relative to the lifting device, and the lifting device is connected with the support part to allow the drive wheel and the lifting device to swing synchronously. The drive wheel structure has the advantages that the first elastic part has a buffer and damping effect, the second elastic part has an obstacle crossing effect, the obstacle crossing and damping functional modules are independent of each other, and the drive wheel structure is good in obstacle crossing and damping effect.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a driving wheel structure and a cleaning device. Background technique [0002] In the related art, the driving wheel of the sweeping robot is a cantilever structure that swings around a fixed axis through a spring. When crossing obstacles, the spring needs to help overcome obstacles and buffer them. However, the gravity of the body of the sweeping robot overcomes the elastic force of the spring. When crossing obstacles, the spring can no longer provide effective buffering for the driving wheels, and the inertia of the robot itself is rigidly eliminated. , the robot will have obvious impact and vibration, and its ability to overcome obstacles is relatively poor. Contents of the invention [0003] Embodiments of the present invention provide a driving wheel structure and a cleaning device. [0004] A driving wheel structure according to an embodiment of the present...
