Motor driving structure and motor driving device

A motor driving device, comprising a motor and a motor driving structure,

• wherein the motor driving structure comprises a driving mechanism, wherein the driving mechanism comprises a lead screw, a nut, a push rod, and a capping head;
• the lead screw is used to be drivingly connected with an output end of the motor;
• the nut is threaded to the lead screw and used for connecting the lead screw with the push rod;
• the push rod is positioned between the nut and the capping head;
• the push rod is integrally formed with the nut and/or the capping head;
• the push rod is made of a plastic material;
• the nut integrated with the push rod and/or the capping head integrated with the push rod are/is made of a plastic material;
• the driving mechanism further comprises a driving gear;
• the driving gear is used to engage with the motor;
• the driving gear is further coaxially connected to the lead screw;
• the driving gear is directly sheathed on the lead screw;
• the driving mechanism further comprises a bearing;
• the bearing is provided on an end of the driving mechanism;
• and the bearing is directly positioned on an end of the driving gear distal to the push rod;
• and
• wherein the motor is used to provide power to the driving mechanism;
• an output end of the motor is provided with an output shaft;
• a housing is provided out of the driving mechanism;
• the housing is provided with a perforation;
• the output shaft is passed through the perforation to be drivingly connected to the lead screw;
• the push rod is further provided with a protective sleeve on an outer periphery thereof;
• the driving mechanism further comprises a fixing member;
• an interior periphery of the fixing member is supported on an outer side of the lead screw;
• and an exterior part of the fixing member is simultaneously supported on an interior periphery of the housing and an interior periphery of the protective sleeve.
