[0016] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0017] The essence of the technical solution of this application is explained in detail below with reference to the accompanying drawings.

[0018] Figure 1 A schematic diagram showing the open and closed states of a heavy-duty door according to an embodiment of the present application is shown. Figure 2 The figure shows a schematic structural diagram of a torque folding arm mechanism for electrically opening and closing a heavy-duty door according to an embodiment of the present application. Figure 3 FIG. 1 shows a schematic diagram of a connecting rod structure of a torque folding arm mechanism for an electric switch heavy-duty door according to an embodiment of the present application. Figure 1 、 Figure 2 and Figure 3 As shown, the folding arm mechanism of the heavy-duty door of the embodiment of the present application includes: a driving motor (not shown in the figure), a driving output component 6, a first push rod 4 and a second push rod 5. The first end of the first push rod 4 is pivotally connected to the driving output component, the second end of the first push rod 4 is pivotally connected to the first end of the second push rod 5, and the second end of the second push rod 4 is pivotally connected to the door leaf support 1 of the heavy-duty door; the driving output component 6 of the embodiment of the present application is fixedly connected to the door frame 2 of the heavy-duty door. Figure 2 As shown, a heavy-duty door has at least two doorframes, one on each side of the door. A drive output component 6 is disposed on the doorframe 2 on one side of the heavy-duty door's pivot structure. A bearing 3 is sleeved around the output shaft of the drive output component 6. The bearing 3 is secured to a support surface and is substantially coplanar with the output shaft of the drive output component 6, enabling the drive output component 6 to output a corresponding torsional force through rotation.

[0019] The output shaft of the drive motor of the present embodiment rotates in a first direction, driving the first push rod 4 and the second push rod 5 in a coordinated manner via the drive output component 6, and driving the door leaf support 1 to move in a second direction, thereby opening the door leaf of the heavy-duty door. The output shaft of the drive motor rotates in a third direction, driving the first push rod 4 and the second push rod 5 in a coordinated manner via the drive output component 6, and driving the door leaf support 1 to move in a fourth direction, thereby closing the door leaf of the heavy-duty door.

[0020] As an example, the driving output component 6 may be a motor reducer.

[0021] In an embodiment of the present application, the first direction may be clockwise, and the third direction may be counterclockwise, and correspondingly, the second direction may be clockwise, and the fourth direction may be counterclockwise; or, the first direction may be counterclockwise, and the third direction may be clockwise, and correspondingly, the second direction may be counterclockwise, and the fourth direction may be clockwise.

[0022] As an example, Figure 1 、 Figure 2 As shown, the drive output component 6 of the embodiment of the present application is arranged on one side of the door frame 2 of the heavy door, that is, on one side of the pivot structure of the heavy door.

[0023] In the embodiment of the present application, the driving motor is arranged in the wall on one side of the door frame of the heavy door.

[0024] As Figure 1 , Figure 3 shown, the first end of the first push rod 4 in the embodiment of the present application is pivotally connected to the driving output component through a first pin shaft 7, and the second end of the first push rod 4 is pivotally connected to the first end of the second push rod 5 through a second pin shaft 8.

[0025] As Figure 3 shown, the driving output component 6, the first push rod 4, the second push rod 5 and the door leaf support 1 in the embodiment of the present application are substantially located in the same horizontal plane to form a four-bar linkage structure. Such a four-bar linkage structure can provide the largest driving force for the heavy door to better push or pull the opening or closing of the heavy door.

[0026] As Figure 3 shown, the length of the second push rod 5 in the embodiment of the present application is greater than the length of the first push rod 4. To enable the four-bar linkage formed by the driving output component 6, the first push rod 4, the second push rod 5 and the door leaf support 1 to have a better power output structure, and also considering that the four-bar linkage structure can better serve as the driving structure of the heavy door, the ratio between the length of the second push rod 5 and the length of the first push rod 4 is between 2 and 1.1.

[0027] The embodiment of the present application also records a heavy-duty protective door, which includes the torque folding arm mechanism for electrically opening and closing the heavy door in the foregoing embodiment.

[0028] In the embodiment of the present application, the driving output component 6 such as a motor reducer and a folding arm mechanism are used to open and close the door leaf of the heavy-duty protective door. By arranging the motor reducer in the door frame wall, the active end of the folding arm is driven by the motor reducer, and the driven end is connected to the upper support of the door leaf. The two push rods and the door frame and the door leaf form a four-bar linkage mechanism, thereby driving the opening and closing of the door leaf of the heavy-duty protective door. The folding arm mechanism of the heavy door in the embodiment of the present application has good anti-strong impact performance during the process of opening and closing the door leaf. Using the folding arm mechanism to open and close the door leaf occupies a small space. Among them, the motor reducer is arranged in the door frame wall, which reduces the dynamic response of the motor reducer when the door body bears strong impact loads.
