Side-hung door device, turnstile, and control method therefor

A side-hung door device, comprising:

• a door leaf;
• a rotating shaft assembly connected to the door leaf;
• a brake assembly connected to the rotating shaft assembly;
• and
• a drive assembly arranged on a turnstile, connected to the brake assembly, and configured to drive the door leaf to rotate,
• wherein the brake assembly comprises:
• an upper end portion and a lower end portion, wherein the lower end portion is connected to the drive assembly and the rotating shaft assembly;
• wherein in a process that the door leaf rotates from an open position toward a closed position and after the door leaf is subjected to an external force greater than or equal to a first preset value, the drive assembly stops driving the rotating shaft assembly, while simultaneously, the brake assembly is powered on, and the lower end portion meshes with the upper end portion to brake the rotating shaft assembly;
• or
• after the door leaf is subjected to an external force greater than a second preset value, the lower end portion and the upper end portion are disengaged to enable the door leaf to displace, wherein the second preset value is greater than the first preset value;
• wherein the side-hung door device further comprises:
• a rotation angle limiting assembly configured to limit a rotation angle of the lower end portion, wherein the rotation angle limiting assembly comprises a rotation angle limiting base, a rotation limiting block connected to the lower end portion and capable of generating axial sliding, and a limiting block arranged on the rotation angle limiting base and configured to limit a rotation angle of the rotation limiting block;
• wherein the rotation limiting block comprises a rotating body and a protrusion portion connected to the rotating body, wherein a groove configured to limit the protrusion portion is provided on the limiting block.

A side-hung door device, comprising:

• a door leaf;
• a rotating shaft assembly connected to the door leaf;
• a brake assembly connected to the rotating shaft assembly;
• and
• a drive assembly arranged on a turnstile, connected to the brake assembly, and configured to drive the door leaf to rotate,
• wherein the brake assembly comprises:
• an upper end portion and a lower end portion, wherein the lower end portion is connected to the drive assembly and the rotating shaft assembly;
• wherein in a process that the door leaf rotates from an open position toward a closed position and after the door leaf is subjected to an external force greater than or equal to a first preset value, the drive assembly stops driving the rotating shaft assembly, while simultaneously, the brake assembly is powered on, and the lower end portion meshes with the upper end portion to brake the rotating shaft assembly;
• or
• after the door leaf is subjected to an external force greater than a second preset value, the lower end portion and the upper end portion are disengaged to enable the door leaf to displace, wherein the second preset value is greater than the first preset value;
• wherein the brake assembly is a jaw brake;
• both the upper end portion and the lower end portion are disc components provided with meshing teeth in end portions, and the meshing teeth are distributed along circumferential directions of the disc components;
• an arrangement direction of the drive assembly is perpendicular to an arrangement direction of the rotating shaft assembly, and the drive assembly is connected to the rotating shaft assembly through a rotating shaft;
• and/or
• at least one of the upper end portion and the lower end portion is provided with an electromagnet that is electrically connected to a servo controller and enables the upper end portion and the lower end portion to adsorb and engage with each other when powered on.
