Abstract
Description
Technical Field
[0001] The invention relates to a door structure. Background Art
[0002] Prior art, such as Chinese utility model patent document, publication number CN220909457U, discloses a mechanical central axis linkage door, comprising an upper mounting plate and a lower mounting plate, the upper mounting plate being fixedly mounted on an external ceiling, the lower mounting plate being fixedly mounted on an external floor, a movable rotating seat being rotatably clamped on the upper mounting plate, a fixed rotating seat being rotatably clamped on the lower mounting plate, a rotating door being installed between the movable rotating seat and the fixed rotating seat, a control motor being fixedly mounted on one side of the upper end of the upper mounting plate, a driven bevel gear being fixedly mounted on the upper end of the rotating column, an active bevel gear being fixedly mounted on the output end of the control motor, a connecting assembly being fixedly mounted at the middle position of the upper end of the upper mounting plate, the connecting assembly being located between the movable rotating seats, the rotating door being able to be quickly disassembled and assembled through the movable rotating seats, thereby realizing quick disassembly and assembly of the rotating door, which is convenient for users, and at the same time, the connecting assembly can connect multiple movable rotating seats to realize synchronous switching or switching one by one.
[0003] Based on the above, in the prior art, the active bevel gear is driven by the control motor to rotate the movable rotating seat to drive the door body to rotate. This structure in which the motor drives the door body to rotate must be used with a reduction gearbox for transmission because the door needs to be opened or closed slowly. During transmission, the motor outputs power to the reduction gearbox, and the power output shaft of the reduction gearbox drives the door to open or close. The problem is that even if the motor is locked after opening or closing the door, the power output shaft cannot be locked. Because the reduction gearbox relies on multiple gears to achieve deceleration through the gear ratio relationship, there will be a gap between the meshing of the gears. The gap provides a rotation space for the power output shaft, which will cause the door body to shake when it is opened or closed. For this reason, the existing electric door body needs to be improved. Utility Model Content

[0027] The power output shaft 300 of the driving element 30 is connected to the first connecting element 40, and the power output shaft 300 rotates to drive the first connecting element 40 to drive the door body 10 to rotate;
[0028] The driving element 30 is provided with a limit assembly 50 for limiting the rotation angle of the power output shaft 300;
[0029] The driving element 30 is provided with a locking mechanism 60 for limiting the rotation of the power output shaft 300 to constrain the rotation of the door body 10 .
[0030] In the above embodiment, the driving element is provided with a limit assembly for limiting the rotation angle of the power output shaft; the driving element is provided with a locking mechanism for limiting the rotation of the power output shaft to constrain the rotation of the door body. The utility model provides a locking mechanism for limiting the rotation of the power output shaft on the driving element, and when opening and closing the door, the power output shaft is locked by the locking mechanism to avoid the problem of shaking of the door body due to external factors.
[0031] At the same time, the utility model sets a limit assembly on the driving element, and when opening and closing the door, the limit assembly constrains the rotation range of the power output shaft, thereby effectively avoiding the problem of over-rotation and under-rotation of the power output shaft. It can avoid the problem of interference and collision between the door body and other problems when over-rotating, and at the same time ensure that the door body is completely closed, avoiding the problem of gaps due to incomplete closure.
[0032] Furthermore, the driving element 30 is composed of a motor and a reduction box, and the power output shaft 300 is the output shaft of the reduction box. By locking the output shaft, the gears inside the reduction box can have a movable gap and the door body can be prevented from shaking.
[0033] See also Figure 6 and Figure 7 The limiting assembly 50 includes a fixed limiting seat 510, a limiting slot 530 is arranged on the limiting seat 510, a first limiting portion 531 and a second limiting portion 532 are arranged at the head end and the end of the limiting slot 530 respectively, a driven limiting piece 520 is arranged in the limiting slot 530, the driven limiting piece 520 is fixedly connected to the power output shaft 300, and a limiting protrusion 521 for abutting and limiting with the first limiting portion 531 or the second limiting portion 532 is arranged on the driven limiting piece 520. In the process of opening and closing the door, the limiting protrusion 521 is located in the limiting slot 530 between the first limiting portion 531 and the second limiting portion 532 and moves. The first limiting portion 531 and the second limiting portion 532 constrain the rotation of the limiting protrusion 521, which can effectively limit the rotation of the door body 10, so as to accurately control the opening and closing of the door body 10.

[0038] The guide hole and the guide pin 650 cooperate to enable the brake pad 620 to move up and down relative to the fixing seat 610. When the brake pad 620 is adsorbed by the electromagnet 630, the fixing seat 610 and the power output shaft 300 are also constrained and cannot rotate.
