Abstract

The invention discloses a brushless motor assembly structure, which comprises a stator assembly (5), an oil bearing (3), a rotor assembly (1), a motor middle pipe (6) and a motor bottom plate (4), and is characterized in that one end of the motor middle pipe (6) is inserted into the motor bottom plate (4) in a close fit manner, and the motor middle pipe (6) is made of a plastic material; the oil bearing is assembled in an inner hole of the motor middle pipe in an interference mode and enables the motor middle pipe to expand towards the motor bottom plate, and the expanded motor middle pipe (6) and the motor bottom plate (4) are connected in a close-fitting mode. According to the invention, the material of the motor middle pipe is changed into the plastic material, and the oil-retaining bearing is assembled in the motor middle pipe in an interference manner to enable the motor middle pipe to expand, so that the expansion assembly of the motor middle pipe and the motor bottom plate can be realized by utilizing the original motor middle pipe, glue does not need to be applied, the technological process is simplified, the cost is lower, and the noise effect is effectively improved. Assembly is simpler, and the reject ratio of secondary assembly can be lower.

Description

technical field [0001] The invention relates to the field of motors, in particular to a brushless motor assembly structure. Background technique [0002] At present, in the motor field of sweeping robots, motor motors are usually used, but this kind of motor needs to use the motor middle tube and the motor bottom plate. The motor bottom plate is used to install and fix the entire motor, so the motor middle tube and the motor bottom plate must be fixedly connected. , the traditional method is generally to put the motor tube into the motor bottom plate and fix it with glue. The way of glue is easy to loosen, which is greatly affected by environmental factors, and the process is more complicated, with high precision requirements and low efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is a brushless motor assembly structure, changing the material of the middle tube of the traditional motor, and using a material with ex...
