The clutch handle 2 includes an installation part 21, which is rotatably connected with the lower casing 100 through a rivet, a first linkage rod 22 and a second linkage rod 23 are arranged along the installation part 21 and outwards form a certain angle, the height of the first linkage rod 22 is higher than that of the second linkage rod 23, in this application, the first linkage rod 22 can include a first connecting rod 221 which is vertical and connected with the installation part 21, and a second connecting rod 222 which is connected with the first connecting rod 221 and horizontal, the height of the specific first connecting rod 221 is higher than that of the limiting column 112, and the second linkage rod 23 is set to be a structure far away from the first linkage rod.

In the application, the height of the limiting column 112 is higher than that of the second linkage rod 23 and is lower than that of the first linkage rod 22 or the height of the limiting column 112 is the same as that of the second linkage rod 22, when the height of the limiting column 112 is higher than that of the second linkage rod 23 and is lower than that of the first linkage rod 22, a groove is formed in the handle body 11 on the side of the limiting column 112, the groove is formed between the limiting column 112 and the installation position of the lower shell 100, a limiting bump 114 is arranged on the handle body 11 between the groove and the installation position, and the structure is arranged so that in the self-closing process, the second linkage block 23 is limited by the limiting bump 114. The second linkage rod 23 can be partially arranged in the groove, so that the parts are prevented from colliding; when the height of the limiting column 112 is the same as that of the second linkage rod 22, the clutch handle is directly limited by the limiting column.

In this embodiment, the clutch handle 2 is installed at one corner of the lower housing 100, during the self-closing process, the first linkage rod 22 of the clutch handle 2 can be abutted to the inner wall of the lower housing, and the positions of the clutch handle and the overrunning handle are not particularly limited, as long as it can be ensured that when the first linkage rod 22 of the clutch handle is abutted to the inner wall of the lower housing, the second linkage rod 23 is crimped to the overrunning handle, the positions of the overrunning handle 1 and the pawl 41 are not particularly limited, but the distance between the overrunning handle 1 and the pawl 41 needs to ensure that when the self-closing process is performed, the push rod 51 rotates clockwise, and when the right vertex 512 of the push rod 511 is abutted to the overrunning handle 1, the left vertex 511 can be abutted to the latch, so as to drive the rotation of the latch 45.

In this embodiment, as shown in fig. 3, an outer opening handle 7 and an inner opening handle 8 are further provided, the outer opening handle 7 is fixedly mounted with the pawl release lever 44, and the inner opening handle 8 is cooperatively linked with the electric release lever 464.

In the self-absorption closing and door closing process, if a passenger needs to open a door, the external opening handle 7 rotates anticlockwise at the moment, the pawl release lever 44 is driven to move, the pawl release lever 44 pulls the clutch connecting rod 3 to enable the clutch handle 2 to be at a second angle, so that the push rod 51 is separated from the bolt 45 to stop suction, and meanwhile, due to the fact that the external opening handle is pulled, after the pawl release lever 44 pushes the caliper 42, the bolt 45 moves clockwise to open the door;

closing the door in-process from inhaling, then opening the side door through interior opening handle, specific: clockwise movement of the inside opening handle 8 moves the electric release lever 464, the electric release lever 464 pushes the pawl release lever 44, and after the pawl release lever 44 pushes the caliper 42, the latch tongue 45 moves clockwise to open the door.

When the clutch handle 2 is arranged at a first angle, the first angle is set to enable the first linkage rod 22 to be abutted against the inner wall of the lower shell 100, and the limit column 112 of the overrunning handle 1 is clamped on the second linkage rod 23; at this time, the driving plate 52 rotates clockwise to push the push rod 51 to rotate clockwise, the right vertex 512 abuts against the limit plate 111, and the left vertex 511 drives the bolt 45 to rotate in the opposite direction, so that the suction and self-locking of the vehicle door are realized.

The clutch handle 2 is arranged at a second angle, and the second angle is set to drive the first linkage rod 22 and the second linkage rod 23 to be separated from the overrunning handle 1 when the clutch handle 2 rotates clockwise; at this time, the transmission plate 52 rotates clockwise to push the push rod 51 to rotate clockwise, the push rod 51 drives the overrunning handle 1 to rotate, and further, the overrunning handle 1 rotates clockwise to a direction far away from the push rod, so that the right vertex 512 of the push rod 51 cannot use the overrunning handle and the clutch handle as fulcrums, and the bolt 45 of the left vertex 511 of the push rod 51 has a gap, so that the suction self-locking of the vehicle door cannot be realized.

The working principle is as follows:

firstly, the working principle of self-closing door closing is as follows:

the cable drives driving plate clockwise movement, and the driving plate drives push rod clockwise motion, and the first gangbar butt of separation and reunion handle is on the casing down this moment, the second gangbar with surmount the handle butt, and the right summit butt of push rod is on the limiting plate of surmounting the handle, and the driving plate continues to rotate to the push rod drives the spring bolt counter-clockwise turning, and then spring bolt drive pawl clockwise motion, stops on the spring bolt buffer block after spring bolt and the pawl meshing, realizes that the electric actuation closes the door and locks entirely.

Secondly, when the passenger need open the door in self-absorption process, the theory of operation does:

the door opening principle of the external opening handle is as follows: the external opening handle rotates anticlockwise to drive the pawl release lever to move, the pawl release lever pulls the clutch connecting rod to move horizontally, the clutch handle rotates clockwise and is separated from the supporting point of the lower shell, meanwhile, the clutch handle cannot be used as a stopping point of the overrunning handle, and the push rod moves along with the overrunning handle, so that a gap exists between the push rod and the lock tongue, and the push rod cannot be automatically attracted; meanwhile, due to the fact that the external opening handle is pulled, after the pawl release lever pushes the calipers, the lock tongue moves clockwise and then opens the door.

The principle of opening the door by adopting the internally-opened handle is as follows: the inner opening handle moves clockwise to drive the electric release lever to move, the electric release lever pushes the pawl release lever, the pawl release lever pulls the clutch connecting rod to move horizontally, so that the clutch handle rotates clockwise and is separated from the supporting point of the lower shell, meanwhile, the clutch handle cannot be used as a stopping point of the overrunning handle, and the push rod moves along with the overrunning handle, so that a gap exists between the push rod and the lock tongue, and the push rod cannot be automatically attracted; meanwhile, due to the fact that the external opening handle is pulled, after the pawl release lever pushes the calipers, the lock tongue moves clockwise and then opens the door.
