Description

Brushless motor with buckle connection mode

Technical Field

The utility model relates to the technical field of brushless motors, in particular to a brushless motor in a buckle connection mode.

Background

In the existing brushless motor, the assembly of the end cover and the shell is fixed in a screw driving mode. Three screw holes are designed on the end cover, three screw holes are designed on the casing, and the specific operation steps are as follows: a staff pre-installs the end cover screw hole in place in alignment with the shell screw hole and sequentially puts three screws into the end cover screw hole; and another worker needs to use an electric screwdriver to respectively lock the three screws, and finally the assembly is finished. In the flow process, three screws are needed to be consumed in the process, two workers need to be arranged for assembly, the motor cost is increased, the working hours are consumed, and the motor production efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a brushless motor of buckle connected mode, includes end cover and shell, shell upper end symmetry is equipped with a plurality of first joint portions, end cover lower extreme symmetry is equipped with a plurality of second joint portions, first joint portion second joint portion with end cover, shell are the integrated into one piece structure.

Preferably, the first clamping portion is composed of a supporting column and a clamping groove.

Preferably, a 45-degree oblique angle is arranged at the edge of the supporting column right above the clamping groove, and the clamping groove is a semicircular clamping groove.

Preferably, the plurality of second clamping parts are composed of elastic arms and buckles.

Preferably, one side of the buckle is a circular arc surface, and the other side of the buckle is a plane.

Advantageous effects

According to the brushless motor adopting the buckle connection mode, the end cover and the shell are assembled without fixing through screwing, during production operation, a worker aligns the buckle on the end cover with the upper oblique angle of the shell, vertically presses the end cover with force, and clamps the buckle into the clamping groove of the shell along the oblique angle, so that the process is finally completed, the buckle assembly structure saves the use of three screws, only one worker is needed to complete assembly, the investment of motor cost is reduced, and the production efficiency is greatly improved.
