[0019] The driving mechanism 7 includes a first connecting ring 701, a first driving rod 702, a second connecting ring 703, a first connecting column 704, a second supporting plate 705, a second driving rod 706, a third connecting ring 707, a second connecting column 708, a third supporting plate 709, a swing motor 710 and a mounting plate 711. The outer surface of the rotating shaft 3 is rotatably connected to the first connecting ring 701, the outer surface of the first connecting ring 701 is fixedly connected to the first driving rod 702, one end surface of the first driving rod 702 is fixedly connected to the second connecting ring 703, and the second connecting ring The inner surface of the first connecting column 703 is rotatably connected to the first connecting column 704, the outer surface of the first connecting column 704 is rotatably connected to the second support plate 705, the outer surface of the second connecting ring 703 is fixedly connected to the second driving rod 706, the outer surface of the second driving rod 706 is fixedly connected to the third connecting ring 707, the inner surface of the third connecting ring 707 is rotatably connected to the second connecting column 708, one side surface of the inner swing door 1 is fixedly connected to the third support plate 709, the interior of the first connecting ring 701 is installed with a swing motor 710, and the lower surface of the swing motor 710 is fixedly connected to the inner side surface of the inner swing door 1. The mounting plate 711 is mounted on the surface of the first connecting ring 701, the first driving rod 702, the second connecting ring 703, the first connecting column 704, the second supporting plate 705, the second driving rod 706, the third connecting ring 707, the second connecting column 708, the third supporting plate 709, the swing motor 710 and the mounting plate 711. When the inner swing door 1 needs to be driven, the swing motor 710 is first turned on. At this time, the swing motor 710 drives the first connecting ring 701 to rotate, thereby driving the first driving rod 702 to rotate, and the first connecting ring 701 is rotated. The connecting ring 701 rotates around the first connecting column 704, and the first connecting column 704 is installed above the second support plate 705. Then the first driving rod 702 drives the second connecting ring 703 to rotate around the first connecting column 704, thereby driving the second driving rod 706 to rotate. The second driving rod 706 drives the third connecting ring 707 to rotate around the second connecting column 708 to push the inner swing door 1 open. The swing motor 710 is installed on one side surface of the door frame 2 through the mounting plate 711, so that the inner swing door 1 can be better pushed open by the swing motor 710.

[0020] Furthermore, the first connecting ring 701 and the rotating shaft 3 form a rotating structure, and the first driving rod 702 and the first connecting column 704 form a rotating structure. Through the setting of the first connecting ring 701, the inner swing door 1 and the door frame 2 can form a rotating structure.

[0021] Furthermore, the third connecting ring 707 and the second connecting column 708 form a rotating structure, and the swing motor 710 is symmetrically arranged with respect to the central axis of the door frame 2 . Through the arrangement of the door frame 2 , the inner swing door 1 can be installed through the door frame 2 .

[0022] Furthermore, the anti-pinch mechanism 8 includes a sensing slot 801, a mounting hole 802, a sensing probe 803, a protective sheet 804, and a controller 805. The sensing slot 801 is provided on one side surface of the inner swing door 1, the mounting hole 802 is provided on one side surface of the sensing slot 801, the sensing probe 803 is installed inside the mounting hole 802, the protective sheet 804 is installed on one side surface of the mounting hole 802, and the controller 805 is installed on one side surface of the inner swing door 1. During use, when it is necessary to prevent fingers from being pinched, first when closing the inner swing door 1, when the sensing probe 803 inside the mounting hole 802 senses that there is a foreign object inside the sensing slot 801, it will transmit a signal to the controller 805, and then the controller 805 controls the swing motor 710 to cut off the power, thereby realizing the anti-pinch function, and the sensing probe 803 can be protected by the setting of the protective sheet 804. Since the inner swing door 1 with the sensing probe 803 is closed faster than the door without the sensing probe 803, it will not affect the normal closing of the two doors.

[0023] Furthermore, the inner wall size of the mounting hole 802 matches the outer wall size of the sensing probe 803 , and the inner wall size of the mounting hole 802 matches the outer wall size of the protective sheet 804 . The sensing probe 803 can be mounted by setting the mounting hole 802 .

[0024] Working principle: When the inner swing door 1 needs to be driven, the swing motor 710 is first turned on. At this time, the swing motor 710 drives the first connecting ring 701 to rotate, thereby driving the first driving rod 702 to rotate. The first connecting ring 701 rotates around the first connecting column 704, and the first connecting column 704 is installed above the second supporting plate 705. Then the first driving rod 702 drives the second connecting ring 703 to rotate around the first connecting column 704, thereby driving the second driving rod 706 to rotate. The second driving rod 706 drives the third connecting ring 707 to rotate around the second connecting column 708 to push the inner swing door 1 open. The swing motor 710 is installed on one side surface of the door frame 2 through the mounting plate 711, so that the inner swing door 1 can be pushed open better through the swing motor 710. When the sensing probe 803 inside the mounting hole 802 senses that there is a foreign object inside the sensing slot 801, it will transmit a signal to the controller 805. Then the controller 805 controls the swing motor 710 to cut off the power, thereby realizing the anti-pinch function. Through the setting of the protective sheet 804, the sensing probe 803 can be protected. Since the inner swing door 1 with the sensing probe 803 closes faster than the door without the sensing probe 803, it will not affect the normal closing of the two doors.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
