Specific implementation mode
Below in conjunction with attached drawing 1-4, specific embodiment of the present utility model is described in further detail, so that the utility model
Technical solution is more readily understood and grasps.
In the present embodiment, it is to be understood that term " centre ", "upper", "lower", " top ", " right side ", " left end ",
" top ", " back side ", " middle part ", etc. instructions orientation or positional relationship be based on the orientation or positional relationship shown in the drawings, only
It is of the invention for ease of description, does not indicate or imply the indicated device or element must have a particular orientation, with spy
Fixed azimuth configuration and operation, therefore be not considered as limiting the invention.
In addition, the connection between component or fixed form if not otherwise specified in this embodiment, connection or solid
Determine mode can be fixed by bolt commonly used in the prior art or pin fix or axis pin connection etc. modes, therefore, this
It is no longer described in detail in embodiment.
With reference to figure 1-4, a kind of high-performance electric pushrod includes bearing 1, and is fixed on the motor cavity on 1 top of bearing
2, and be integrally formed with motor cavity 2 and be integrally formed positioned at the motor base 3 on 2 top of motor cavity, and with the motor base 3
And positioned at the sleeve 4 on 3 top of motor base, and it is slidably connected to the piston rod 5 inside sleeve 4, and inside piston rod 5
Lead screw 9.In the present embodiment, the piston rod 5 is in hollow setting, can mitigate the weight of the high-performance electric pushrod；Institute
