Linear driving mechanism with integrated housing having gear ring and slide rail

A linear driving mechanism comprising:

• a driving assembly and a transmission assembly fixedly connected to each other;
• wherein the driving assembly comprises:
• a first housing,
• a stator assembly provided within the first housing, and
• a rotor assembly provided within the stator assembly,
• wherein the rotor assembly is arranged through an end of the first housing close to the transmission assembly, and the stator assembly is configured to drive the rotor assembly to rotate;
• the transmission assembly comprises:
• a second housing,
• a first cover plate fixed to an end of the second housing away from the driving assembly,
• a gear assembly mounted on an end of the second housing close to the driving assembly,
• a screw rod fixed in the second housing and located on a side of the gear assembly away from the driving assembly,
• a push rod provided in the second housing and located on a side of the screw rod away from the driving assembly, and
• a connector located at an end of the gear assembly close to the driving assembly and rotatably connected to the gear assembly,
• wherein an end of the connector close to the driving assembly is fixedly connected to an output end of the rotor assembly, the push rod is arranged through the first cover plate and forms a sliding connection with the first cover plate, and the screw rod forms a linear transmission connection with the push rod;
• the second housing comprises:
• a hollow housing body,
• a gear ring formed in the housing body by a recess extending from an end of the housing body close to the driving assembly toward an end of the housing body away from the driving assembly, and
• a slide rail formed in the housing body by a recess in an inner peripheral side of the housing body,
• wherein the slide rail extends from the end of the housing body away from the driving assembly to the end of the housing body close to the driving assembly;
• the gear assembly is supported on a side of the gear ring close to the driving assembly and is engaged with the gear ring, and the push rod forms a sliding connection with the slide rail.
