Detailed ways

In order to make the objects, technical solutions and advantages of the present application more clear, the tooling of the assembled display assembly of the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

The motor mounting structure shown in FIG. 1 and FIG. 2 includes a first motor mounting bracket 10, and the motor is disposed on the first motor mounting bracket 10, and further includes a second motor mounting bracket 30 and a primary damping device 40. The first motor mounting bracket 10 is disposed on the second motor mounting bracket 30, and the primary damping device 40 is disposed between the first motor mounting bracket 10 and the second motor mounting bracket 3.

The vibration generated by the motor can transmit the vibration of the motor to the motor mount from the low frequency to the high frequency region by the two damping effects of the primary damping device 20 and the primary damping device 40. .

The first motor mounting bracket 10 and the second motor mounting bracket 30 are both disposed at one end away from the output shaft of the motor, that is, the first motor mounting bracket 10 and the second motor mounting bracket 30 are fixed. One end of the motor ensures that no interference is generated around the output shaft of the motor.

The second motor mounting bracket 3 is provided with a mounting hole through which the motor body passes.

Preferably, a middle portion of the first motor mounting frame 10 is provided with a motor mounting hole for mounting a motor, a middle portion of the second motor mounting frame 30 is provided with a mounting hole, and one end of the motor is disposed at one of the mounting holes a side, the other end is disposed on the other side of the mounting hole, and is disposed on the first motor mounting frame 10. During the installation process, the motor is first installed in the motor mounting hole, and then the output of the motor is After the shaft passes through the mounting hole, the first motor mounting bracket 1 is engaged with the second motor mounting bracket 30, but the first motor mounting bracket 10 is not passed through the mounting hole, After the first motor mount 1 and the second motor mount 3 are fixed, the installation work of the motor is completed.
