Based on the above problems, the present application makes improvements, and embodiments solving the above problems will be given below. Referring to fig. 1, the side of the doorway near the connection position of the door frame 13 and the first mounting plate 8 is a first side, and the first link 2 is disposed between the third link 4 and the first side. The sliding door 1 has a closed door state and an open door state. Referring to fig. 2 to 4, the door-opened state is the state in which the sliding door 1 is completely slid out of the doorway. Referring to fig. 5 to 7, in the closed state, the sliding door 1 covers the doorway, and the driving device drives the third pivot to rotate, so that the sliding door 1 is switched between the open state and the closed state.
During the process of switching the sliding door 1 from the door-closed state to the door-open state (switching the sliding door 1 from the state of fig. 5 to the state of fig. 2):
referring to fig. 6 and 7, when the sliding door 1 is closed, the sliding door 1 covers the entrance, an included angle between the third link 4 and the fourth link 5 away from the second pivot is less than 180 degrees, an included angle between the fixed seat 10 and the sixth link 7 away from the first side is less than 180 degrees, and an included angle between the third link 4 and the fourth link 5 away from the second pivot is greater than an included angle between the fixed seat 10 and the sixth link 7 away from the first side.
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 mechanism to rotate clockwise, that is, the second end of the first link 2 and the second end of the third link 4 move toward the first side. And a second four-bar linkage 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, the second four-bar linkage mechanism rotates clockwise under the limit of the sixth connecting bar 7 until the extending direction of the fixed 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 state, namely, between an open state and a closed state.
When the door is in a half-open state, an included angle between the third connecting rod 4 and the fourth connecting rod 5 far away from one side of the second pivot is equal to 180 degrees, and an included angle between the fixed seat 10 and the sixth connecting rod 7 far away from one side of the first side is equal to 180 degrees.
Referring to fig. 3 and 4, after the sliding door 1 is in the half-open state, the driving device continues to drive the third pivot to rotate clockwise, so that the included angle between the third link 4 and the fourth link 5 away from the second pivot is greater than 180 degrees, and meanwhile, the included angle between the fixed seat 10 and the sixth link 7 away from the first side is greater than 180 degrees until the open state is reached.
During the process of switching the sliding door 1 from the door-open state to the door-closed state (switching the sliding door 1 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, an included angle between the third link 4 and the fourth link 5 away from the second pivot is greater than 180 degrees, an included angle between the fixed seat 10 and the sixth link 7 away from the first side is greater than 180 degrees, and an included angle between the third link 4 and the fourth link 5 away from the second pivot is greater than an included angle between the fixed seat 10 and the sixth link 7 away from the first side.
The driving device drives the third pivot to rotate anticlockwise, so that a first four-bar linkage formed among the first link 2, the third link 4, the fifth link 6 and the first mounting plate 8 rotates anticlockwise, namely the second end of the first link 2 and the second end of the third link 4 move back to the first side. And a second four-bar linkage 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, the second four-bar linkage mechanism rotates anticlockwise under the limit of the sixth connecting bar 7 until the extending direction of the fixed 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 state, namely, between a door opening state and a door closing state.
When the door is in a half-open state, an included angle between the third connecting rod 4 and the fourth connecting rod 5 far away from the second pivot is equal to 180 degrees, and an included angle between the fixing seat 10 and the sixth connecting rod 7 far away from the first side edge 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 seat 10 are parallel.
Referring to fig. 6 and 7, after the sliding door 1 is in the half-open state, the driving device continues to drive the third pivot to rotate counterclockwise, so that the included angle between the third link 4 and the fourth link 5 away from the second pivot is less than 180 degrees, and the included angle between the fixed seat 10 and the sixth link 7 away from the first side is less than 180 degrees until the door is closed.
In summary, compared with the conventional method of connecting the door frame 13 and the sliding door 1 by the conventional four-bar linkage structure, the sliding door 1 of the embodiment of the present invention has a higher sliding stroke in the front-rear direction of the vehicle when the first link 2 and the third link 4 have the same swing amplitude and angle. Meanwhile, the embodiment of the invention can also reduce the moving space of the first connecting rod 2 and the third connecting rod 4 in the opening and closing processes of the sliding door 1, namely, under the condition that the stroke of the sliding door 1 is increased, the invasion amount of the first connecting rod 2 and the third connecting rod 4 to the space in the vehicle when the sliding door 1 is closed can be reduced, and the comfort of passengers is improved.
In addition, the sixth link 7 of the present invention limits the position of the fourth link 5, and the fourth links 5 all have positions corresponding to the third links 4 one to one in the process of moving the third links 4, so that it is possible to ensure that the opening and closing processes of the sliding door 1 have unique trajectories when the stroke of the sliding door 1 is increased.
