Further, referring to the structure shown in fig. 2, the first and second ends of the relay rotation arm 32 are disposed opposite to each other with respect to the rotation center of the relay rotation arm 32, so that when the pulling of the pulling cable 33 to the left in fig. 2 is performed, the first and second links 12 and 22 move to the right in fig. 2.

In addition, a lock ring is provided at each of a door opening position and a door closing position of the sliding door, the first lock body member 10 and the rear lock ring 19 form a locking structure at the door closing position, and the second lock body member 20 and the lower lock ring form a locking structure at the door opening position. When the door needs to be opened, the first lock body member 10 and the rear lock ring 19 can be unlocked through the first pull rod 12, and when the door needs to be closed, the second lock body member 20 and the lower lock ring can be unlocked through the second pull rod 22.

Wherein, when the sliding door moves from the door closing position to the door opening position, the second lock body member 20 can form a locking structure with the lower lock ring when the second lock body member collides with the lower lock ring under the action of inertia. Likewise, when the sliding door moves from the door open position to the door closed position, the first lock body member 10 is able to form a locking structure with the rear lock ring when it collides with the rear lock ring under the action of inertia.

As shown in fig. 1, the lock structure of the electric sliding door includes a control portion 30, where the lock structure includes the control portion 30, the control portion 30 is electrically connected to the motor 11, and the control portion 30 can receive an electrical signal transmitted from the outside, and can transmit a signal to the motor 11 according to the electrical signal, so as to control the first lock body member to switch from the locked state to the unlocked state, and control the second lock body member to switch from the locked state to the unlocked state.

The sliding door can be locked at a door closing position by the first lock body piece, the first lock body piece comprises a rear lock unlocking rotating arm 16, a rear lock unlocking pull rod 17 and a rear lock bolt 18, the rear lock unlocking rotating arm 16 is arranged on the first mounting substrate in a pivoted mode, and the first end of the rear lock unlocking rotating arm 16 is connected with the first pull rod 12; the rear lock unlocking lever 17 and the rear lock tongue 18 are both pivotably provided on the first mounting substrate.

When the execution cable 33 pulls the transfer rotating arm 32 to rotate on the transfer main body member 31 around the pivot shaft thereof, the first pull rod 12 is pulled by the transfer rotating arm 32, and further pulls the rear lock unlocking rotating arm 16 to rotate, the rear lock unlocking rotating arm 16 can rotate on the first mounting substrate around the pivot shaft 34, and when the first pull rod 12 pulls the rear lock unlocking rotating arm 16 to rotate, the rear lock unlocking rotating arm 16 can rotate on the first mounting substrate around the pivot shaft 34, wherein the rear lock unlocking rotating arm 16 can contact the rear lock unlocking pull rod 17 in the rotating process, so that the rear lock unlocking pull rod 17 can rotate on the first mounting substrate around the pivot shaft thereof.

When the first lock body member is in the locked state, the rear lock tongue 18 and the rear lock locking ring 19 form a buckling, and when the output end of the motor 11 rotates in the first direction, the first pull rod 12 drives the rear lock unlocking rotating arm 16 to rotate through the first end of the rear lock unlocking rotating arm 16, so that the second end of the rear lock unlocking rotating arm 16 pushes the first end of the rear lock unlocking pull rod 17, the rear lock unlocking pull rod 17 is pushed to pivot around the rear lock unlocking pull rod 17, and the second end of the rear lock unlocking pull rod 17 pushes the rear lock tongue 18 to rotate, so that the rear lock tongue 18 is separated from buckling with the rear lock locking ring 19, and the electric sliding door located at the door closing position is unlocked, so that the electric sliding door can be moved to the door opening position.

When the sliding door moves from the door opening position to the door closing position, the first locking body member and the rear locking ring 19 can be locked to a certain extent by the inertia force, and the rear locking tongue 18 and the rear locking ring 19 do not form complete buckling although the locking effect can be achieved, so that the stability of the locking is not very high, and particularly, in the door closing position, in order to prevent the door from being suddenly opened or failing during the running of the automobile, the locking requirement is higher in the door closing position. The present application therefore regards the locking between the first lock body member and the rear lock ring, which is formed by inertia, not as a locked state, but as an unlocked state, and also enables the first lock body member to be switched to a locked state by the motor 11 when the door is moved to the closed position.

Referring specifically to the structure shown in fig. 4, 5 and 6, the first lock body member further includes an engaging rotating arm 71, an engaging rotating arm rotating shaft 72 and an engaging rotating arm connecting member 73, the engaging rotating arm 71 is pivotally provided on the first mounting substrate through the engaging rotating arm rotating shaft 72, and the engaging rotating arm 71 is fixedly provided on the gear rotating arm 15 through the engaging rotating arm connecting member 73, so that when the gear rotating arm 15 rotates, the rotation of the gear rotating arm 15 can drive the engaging rotating arm 71 to rotate together because the engaging rotating arm 71 is fixedly connected with the gear rotating arm 15 through the engaging rotating arm connecting member 73.

In the unlocked state of the first lock body member, when the motor 11 rotates in a second direction opposite to the first direction, the gear rotating arm 15 drives the attraction rotating arm 71 to rotate around the attraction rotating arm rotating shaft 72 through the attraction rotating arm connecting piece 73, so that the attraction rotating arm 71 can push the rear lock tongue 18 to rotate, and the rear lock tongue 18 and the rear lock ring 19 form further buckling, so that the first lock body member is switched to the locked state. In this state, the first lock body member has good stability, so that the occurrence of unexpected opening or failure of the door during running of the automobile is effectively prevented.

With continued reference to the structure shown in fig. 2, the transfer portion further includes a transfer opening rotation arm 36, and the transfer opening rotation arm 36 is connected to the transfer rotation arm 32 to drive the transfer rotation arm 32 to rotate. Thus, the rear lock tongue 18 can be rotated by swinging the turn-on rotation arm 36 without using a motor. Specifically, the transfer opening rotating arm 36 is fixedly connected with the transfer rotating arm 32, and when the transfer opening rotating arm 36 is rotated, the transfer rotating arm 32 can rotate together with the transfer opening rotating arm 36, so as to finally realize that the rear lock tongue 18 and the rear lock ring 19 are disengaged from each other. The transfer rotating arm 32 and the opening rotating arm 36 may be connected together on the same pivot shaft, and when the opening rotating arm 36 rotates, the pivot shaft rotates to drive the transfer rotating arm 32 to rotate together.

The opening and turning arm 36 can be connected to, for example, an automobile having the electric sliding door apparatus, and in an emergency, a passenger can directly turn the opening and turning arm 36 to open the sliding door and leave the automobile. For example, an opening may be formed in the inner cavity of the sliding door, and the extreme end of the opening rotation arm 36 is exposed, so that the passenger can directly rotate the exposed portion of the opening rotation arm 36 to open the sliding door, thereby enabling the passenger to open the vehicle door in an emergency.

As shown in fig. 7 and 8, in order to unlock the sliding door at the door opening position so that the sliding door can be moved to the door closing position, the second lock body member includes a second mounting base plate, a lower lock unlocking rotation arm 21, and a lower lock spring, the lower lock unlocking rotation arm 21 is pivotally provided on the second mounting base plate, and a protruding end of the lower lock unlocking rotation arm 21 is connected to the second pull rod 22; the lower lock spring is arranged on the second mounting substrate and is connected with the lower lock bolt 23.

As shown in fig. 7, when the second lock body member is in the locked state, at this time, the second pull rod 22 pulls the protruding end of the lower lock unlocking rotating arm 21, and since the protruding end of the lower lock unlocking rotating arm 21 and the pivot axis of the lower lock unlocking rotating arm are disposed at intervals, when the second pull rod 22 pulls the lower lock unlocking rotating arm 21 to rotate, the lower lock unlocking rotating arm 21 can rotate around the pivot axis thereof, that is, the lower lock unlocking rotating arm 21 will move in the clockwise direction, at this time, under the action of the lower lock spring, the lower lock tongue 23 spring is pressed to move in the counterclockwise direction, so as to be separated from and moved to the position separated from the lower lock ring, that is, the state shown in fig. 8. At this time, even if the second pull rod 22 does not pull the lower lock unlocking rotation arm 21 any more, the locking end of the lower lock unlocking rotation arm 21 cannot be hooked with the lower lock tongue 23 any more.

The sliding door 40 moves from the door opening position to the door closing position, and the second locking member always maintains the state shown in fig. 6, and when the sliding door 40 moves from the door closing position to the door opening position, the side portion of the lower locking bolt 23 (the right side of the lower locking bolt in fig. 8) touches the lower locking ring at the moment of reaching the door opening position, and the impact force fed back by the lower locking ring to the lower locking bolt 23 causes the lower locking bolt 23 to move in the clockwise direction, so that the top portion of the lower locking bolt 23 and the locking end of the lower locking unlocking rotating arm 21 form a hook again, that is, the state shown in fig. 7.
