Based on the above-described problems, the present application has been improved, and examples for solving the above-described problems will be given below. The side of the doorway, which is close to the connection position of the door frame 13 and the first mounting plate 8, is a first side, and the first connecting rod 2 is disposed between the third connecting rod 4 and the first side, as shown in fig. 1. The sliding door 1 has a closed door state and an open door state. Referring to fig. 2 to 4, the door opening state is a state in which the sliding door 1 is completely slid out of the doorway. Referring to fig. 5 to 7, in the door closing state, the sliding door 1 is covered on the doorway, and the sliding door 1 is switched between the door opening state and the door closing state by driving the third pivot shaft to rotate by the driving device.
During the process of switching the sliding door 1 from the door-closed state to the door-open state (the sliding door 1 is switched from the state of fig. 5 to the state of fig. 2):
referring to fig. 6 and 7, when the sliding door 1 is in the door-closing state, the sliding door 1 covers the doorway, the included angle between the third connecting rod 4 and the fourth connecting rod 5, which is far away from the second pivot, is smaller than 180 degrees, meanwhile, the included angle between the fixing base 10 and the side, which is far away from the first side, of the sixth connecting rod 7 is smaller than 180 degrees, and the included angle between the third connecting rod 4 and the side, which is far away from the second pivot, of the fourth connecting rod 5 is larger than the included angle between the fixing base 10 and the side, which is far away from the first side, of the sixth connecting rod 7.
Referring to fig. 6 and 7, the driving device drives the third pivot to rotate clockwise, so that the first link 2, the third link 4, the fifth link 6 and the first mounting plate 8 form a four-bar linkage to rotate clockwise, that is, the second end of the first link 2 and the second end of the third link 4 move towards the first side. And a second four-bar mechanism is formed among the second connecting bar 3, the fourth connecting bar 5, the fifth connecting bar 6 and the second mounting plate 9, and the second four-bar mechanism rotates clockwise under the limit of the sixth connecting bar 7 until the extending direction of the fixing seat 10, the sixth connecting bar 7, the third connecting bar 4 and the fourth connecting bar 5 are parallel, and at the moment, the sliding door 1 is in a half-open door state, namely, is in a door opening state and a door closing state.
In the half-open state, the included angle between the third connecting rod 4 and the fourth connecting rod 5 at the side far away from the second pivot is equal to 180 degrees, and meanwhile, the included angle between the fixing seat 10 and the side of the sixth connecting rod 7 at the side far away from the first side is equal to 180 degrees.
Referring to fig. 3 and 4, after the sliding door 1 is in the half-open door state, the driving device continues to drive the third pivot to rotate clockwise, so that the included angle between the third connecting rod 4 and the fourth connecting rod 5, which is far away from the second pivot, is greater than 180 degrees, and meanwhile, the included angle between the fixing base 10 and the sixth connecting rod 7, which is far away from the first side, is greater than 180 degrees until the door is opened.
During the process of switching the sliding door 1 from the door-open state to the door-closed state (the sliding door 1 is switched from the state of fig. 2 to the state of fig. 5):
referring to fig. 3 and 4, when the sliding door 1 is in the door-opening state, the included angle between the third connecting rod 4 and the fourth connecting rod 5 is greater than 180 degrees from the side of the second pivot, meanwhile, the included angle between the fixing base 10 and the side of the sixth connecting rod 7, which is far from the first side, is greater than 180 degrees, and the included angle between the third connecting rod 4 and the side of the fourth connecting rod 5, which is far from the second pivot, is greater than the included angle between the fixing base 10 and the side of the sixth connecting rod 7, which is far from the first side.
The driving device drives the third pivot to rotate anticlockwise, so that a first four-bar mechanism is formed among the first connecting rod 2, the third connecting rod 4, the fifth connecting rod 6 and the first mounting plate 8, namely the second end of the first connecting rod 2 and the second end of the third connecting rod 4 move away from the first side. And a second four-bar linkage is formed among the second connecting bar 3, the fourth connecting bar 5, the fifth connecting bar 6 and the second mounting plate 9, and the second four-bar linkage rotates anticlockwise under the limit of the sixth connecting bar 7 until the extending direction of the fixing seat 10, the sixth connecting bar 7, the third connecting bar 4 and the fourth connecting bar 5 are parallel, and at the moment, the sliding door 1 is in a half-open door state, namely, is in a door opening state and a door closing state.
In the half-open state, the included angle between the third connecting rod 4 and the fourth connecting rod 5 at the side far away from the second pivot is equal to 180 degrees, and meanwhile, the included angle between the fixing base 10 and the side far away from the first side of the sixth connecting rod 7 is equal to 180 degrees, so that the first connecting rod 2, the second connecting rod 3, the sixth connecting rod 7 and the fixing base 10 are parallel.
Referring to fig. 6 and 7, after the sliding door 1 is in the half-open door state, the driving device continues to drive the third pivot to rotate anticlockwise, so that an included angle between the third connecting rod 4 and one side of the fourth connecting rod 5, which is far away from the second pivot, is smaller than 180 degrees, and meanwhile, an included angle between the fixing base 10 and one side of the sixth connecting rod 7, which is far away from the first side, is smaller than 180 degrees until the door closing state is reached.
