Handle assembly

A handle assembly for a door having a handle aperture, comprising:

• a housing defining a cavity and having a housing opening in communication with the cavity, and the housing opening configured to be aligned with the handle aperture of the door;
• a cover plate having a closed position and an open position, and the cover plate configured to close the handle aperture of the door in the closed position and to open the handle aperture of the door in the open position;
• a transmission device disposed in the housing and connected to the cover plate, wherein the transmission device is configured to move the cover plate between the closed position and the open position in response to an electronic signal and, when the cover plate is in the closed position, and move the cover plate to the open position by a pushing force from outside of the cover plate;
• and
• a limiting structure disposed on the cover plate;
• and
• a limiting fit structure disposed on the housing, wherein the limiting structure is engaged with the limiting fit structure,
• wherein the transmission device, the limiting structure and the limiting fit structure enable the cover plate to move between the closed position and the open position,
• wherein the limiting fit structure comprises a track slot formed on a side wall of the housing, and the limiting pin is configured to slide in the track slot, and
• wherein the track slot is a straight slot, and the track slot extends obliquely upward in a front-rear direction.

A handle assembly for a door having a handle aperture, comprising:

• a housing defining a cavity and having a housing opening in communication with the cavity, the housing opening being configured to align with the handle aperture of the door;
• a cover plate movable between a closed position, in which the handle aperture is closed, and an open position, in which the handle aperture is open;
• a transmission device disposed in the housing and operatively connected to the cover plate, the transmission device being configured to move the cover plate between the closed position and the open position in response to an electronic signal and, when the cover plate is in the closed position, to permit movement of the cover plate to the open position in response to a pushing force applied from outside the cover plate, the transmission device comprising:
• a rotating shaft configured to rotate in response to an electronic signal or a mechanical force, the rotating shaft extending along an entire length of the cover plate;
• a driving gear;
• and
• a transmission gear meshing with the driving gear and being in transmission connection between the rotating shaft and the driving gear, such that rotation of either the driving gear or the rotating shaft drives the transmission gear and thereby rotates the other of the driving gear and the rotating shaft,
• wherein the driving gear and the transmission gear are configured such that, in response to the electronic signal, the driving gear is driven by a motor to rotate the transmission gear and thereby move the cover plate, and, in response to the pushing force applied from outside the cover plate, the cover plate rotates the rotating shaft to rotate the transmission gear and thereby drive the driving gear;
• at least one connecting member having a first end connected to the rotating shaft for rotation therewith and a second end rigidly hinged to the cover plate such that rotation of the rotating shaft moves the cover plate and movement of the cover plate rotates the rotating shaft;
• and
• a limiting structure disposed on the cover plate and a limiting fit structure disposed on the housing and engaged with the limiting structure, the transmission device, the limiting structure, and the limiting fit structure cooperating to guide movement of the cover plate between the closed position and the open position,
• wherein the rotating shaft extends axially from the transmission gear.
