[0002] As customer requirements become more diverse, the requirements for passenger door structures are becoming increasingly demanding. Existing passenger doors are mostly simple structures, with inward-swinging passenger doors being the most common. However, since these doors open inward, they take up more interior space. Outward-swinging doors, which open outward, are becoming a market trend. Existing outward-swinging doors mostly use an external door pump to control the opening, closing, lifting, and locking of the passenger door.

[0003] Traditional pneumatic lift-outward swing doors have the following drawbacks: they are unstable due to the influence of the air source, are noisy during opening and closing, and the anti-pinch function is easily lost, posing a safety hazard; the pneumatic cylinder drive wastes energy; and the anti-pinch function sensitivity is difficult to adjust. Switching from pneumatic to electric lift-outward swing doors also has the following drawbacks: the external door shaft drive requires more space inside the vehicle; and traditional electric lift-outward swing doors are heavy.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] See Figure 1-4 , Figure 1 This is a schematic structural diagram of an embodiment of an air brake motor brake for an outward swing door of the present application. The brake comprises: a base plate 1, a drive motor 2, a reducer 4, a rotating disc 5, and a transmission rod assembly 6; a bottom plate 7 is fixedly connected to the base plate 1, a first shaft hole 71 is provided in the bottom plate 7, and the rotating disc 5 is movably sleeved in the first shaft hole 71 via a rotating shaft; the upper end of one side of the base plate 7 is connected to the motor plate 41 via a column 42, the reducer 4 is mounted on the motor plate 41, and the bottom rotating shaft of the reducer 4 is engaged with the rotating disc 5 via a high and low gear plate 8; the drive motor 2 is connected to one side of the reducer 4, and the rotating disc 5 is connected to the door shaft assembly 9 via the transmission rod assembly 6, wherein the end of the drive motor 2 is provided with an air brake disc 3. The drive motor 2 in the above design controls the rotation angle of the high and low gear plate 8 and the rotating disc 5 through the reducer 4, thereby driving the transmission rod assembly 6 connected to the door shaft assembly 9 to move back and forth to control the rotation of the door shaft assembly 9.

[0022] The top end of the rotating disk 5 is provided with a first stopper 51 and a flange 52 positioned above the first stopper 51. The flange 52 is provided with a first connecting post 53, which is movably connected to the transmission rod assembly 6. The outer edge of the rotating disk 5 is provided with conical teeth that mesh with the high-low gear plate 8. In the above-described design, the rotating disk 5 rotates within the first shaft hole 71. The rotating disk 5 is driven by the drive motor 2 and the high-low gear plate 8, thereby driving the flange 52.

[0023] The shaft of the reducer 4 passes through the motor plate 41 and is connected to the drive gear 43, which meshes with the high-low gear plate 8. The reducer 4 in the above design can proportionally reduce the speed of the drive motor 2, making it easier to control the rotation angle of the drive gear 41 and the rotating plate 5, thereby controlling the opening and closing of the external flap door.

[0024] The bottom plate 7 is provided with a second axial hole 72 located at the side end of the first axial hole 71. The central rotating shaft of the high-low gear plate 8 is movably disposed in the second axial hole 72. The high-low gear plate 8 is located between the motor plate 41 and the bottom plate 7. The second axial hole 72 in the above design can be movably inserted into the high-low gear plate 8, and the high-low gear plate 8 can be connected to the driving gear 41 and the rotating disk 5.

[0025] The high-low gear plate 8 includes a first toothed plate 81 meshing with the drive gear 41 and a second toothed plate 82 meshing with the rotating plate 5. The outer diameter of the first toothed plate 81 is larger than the outer diameter of the second toothed plate 82. The high-low gear plate 8 in the above design is divided into two layers, the first toothed plate 81 on the upper layer meshing with the drive gear 41 and the second toothed plate 82 on the lower layer meshing with the rotating plate 5. This allows the driving force of the drive gear 41 to be transmitted to the rotating plate 5, thereby controlling the rotation of the rotating plate 5 and the flange 52.

[0026] The air brake disc 3 is mounted on the rotor of the drive motor 2 and has an air inlet 31 on its outer side. The air brake disc 3 in this design can be connected to an external compressed air pipe. When the pipe is ventilated, the air brake disc 3 closes and stops the rotor of the drive motor 2, providing additional protection when the motor stops, preventing accidental rotation or external forces from affecting the motor.

[0027] The door hinge assembly 9 includes a door hinge 91 and a pivot arm 92. A door hinge hole 11 is provided at the end of the base plate 1. The door hinge 91 is sleeved in the door hinge hole 11 via a bearing. One end of the pivot arm 92 is fixed to the upper end of the door hinge 91. The other end of the pivot arm 92 is provided with a second connecting post 93 connected to the transmission rod assembly 6. The door hinge 91 in the above design is connected to the door hinge 91 of the inner swing door, and the rotation of the pivot arm 92 can drive the rotation of the door hinge 91, thereby controlling the opening and closing of the inner swing door.

[0028] The transmission rod assembly 6 includes a transmission rod 61 and collars 62 at both ends of the transmission rod 61. The collar 62 at one end of the transmission rod 61 movably engages the first connecting post 53; the collar 62 at the other end of the transmission rod 61 movably engages the second connecting post 93. In the above-described design, the transmission rod 61 connects the flange 52 and the pivot arm 92 on the door shaft 91. Rotation of the flange 52 drives the back-and-forth movement of the transmission rod 61, thereby driving the rotation of the pivot arm 92 and the door shaft 91 to control the opening and closing of the inward swing door.

[0029] A first stopper 54 corresponding to the first stop block 51 is provided on the side of the rotating disk 5 away from the drive motor 2. The first stopper 54 in the above design can limit the maximum rotation angle of the convex disk 52, thereby ensuring that the transmission displacement distance reaches the maximum and the rotation angle of the rotating arm 92 and the door shaft 91 reaches the maximum.

[0030] A second stopper 94 is provided on the outside of the door shaft hole, and a second stopper block 95 corresponding to the second stopper 94 is provided on the outside of the door shaft 91. The second stopper 94 in the above design can make the second stopper block 95 contact the second stopper 94 when the door shaft 91 rotates, limiting the rotational position of the rotating arm 92 when closing the door, so as to ensure that the door shaft 91 does not rotate excessively.

[0031] The specific working principle is to connect the external pneumatic air pipe to the solenoid valve 32 and the dehumidifier 33, and then connect it to the air inlet 31 of the air brake disc 3. The start and stop of the air brake disc 3 is controlled by the solenoid valve 32. When the door needs to be opened, the drive motor 2 rotates, and at the same time, the drive gear 41 drives the high and low gear plates 8 and the rotating plate 5 to rotate to a preset angle. When the convex part of the cam 52 reaches the position of the first limiter 54, the drive motor 2 stops, and the solenoid valve 32 controls the air pipe ventilation so that the air brake disc 3 starts to completely brake the drive motor 2 to prevent accidental rotation or external forces from affecting the motor. At the same time, the rotation of the cam 52 drives the transmission rod 61 to move, thereby driving the rotating arm 92 and the door shaft 91 to rotate, so that the inner swing door opens. When the door needs to be closed, the solenoid valve 32 closes the ventilation and the air brake disc 3 is released. The driving motor 2 rotates, controlling the rotating disk 5 and the cam 52 to rotate, thereby driving the transmission rod 61 to move back and rotate the rotating arm 92 to rotate the door shaft 91, so that the inner swing door is closed. When the limit block on the outside of the door shaft 91 contacts the second limiter 94, the driving motor 2 stops, the solenoid valve 32 controls the air pipe ventilation, and the driving motor 2 is braked again through the air brake disc 3.

[0032] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or any direct or indirect application of the relevant technical fields, are also included in the patent protection scope of the present application.
