When the manual shifting element 13 is shifted, the hand-held segment 132 rotates on a plane parallel to the first reference plane, and the emergency lever 121 is pushed by the shifting segment which is arranged diagonally to the first reference plane.

Further, as shown in fig. 3 to 5, in one embodiment, the latch bolt unit 11 includes a lock block 111 and a link mechanism. The locking piece 111 is provided with a locking notch 1111, the locking piece 111 is rotatably connected with the lock cylinder housing 151 through a first rotating shaft 1112, and the locking piece 111 has a tendency to return to the unlocking position. The lock notch 1111 is located at the position of the lock groove 1514, when the lock rod is pressed into the lock groove 1514, the lock rod enters the lock notch 1111, and as the lock rod further moves into the lock groove 1514, the lock block 111 is pushed by the lock rod and rotates relative to the lock cylinder housing 151. When the lock block 111 rotates to the opening of the locking notch 1111 faces away from the opening of the locking groove 1514, or when the orientation of the locking notch 1111 forms an obtuse angle with the opening of the locking groove 1514, the lock rod is enclosed in the locking notch 1111 and the locking groove 1514.

The locking unit 12 further includes a stop block 122, the emergency lever 121 is connected to the stop block 122, the stop block 122 is rotatably connected to the lock cylinder housing 151 through a second rotating shaft 1221, and when the emergency lever 121 is pushed by the driving unit 14 or the manual dialing member 13 to move, the stop block 122 rotates. The first rotating shaft 1112 and the second rotating shaft 1221 are respectively located at two sides of the locking groove 1514.

The tongue unit 11 further includes a link mechanism, the link mechanism is located between the driving unit 14 and the locking piece 111, when the electric automobile rear door lock 10 is in an unlocking state or a half-locking state, the driving unit 14 can indirectly drive the locking piece 111 to rotate through the link mechanism, so that the locking piece 111 can overcome the aforesaid tendency of resetting to the unlocking position and rotate to the locking position.

Specifically, as shown in fig. 5, the link mechanism includes a fixed shaft link 112, a movable shaft link 113, and a locking input shaft 114, the locking input shaft 114 is connected to the fixed shaft link 112, and an axis of the locking input shaft 114 is parallel to an axis of the emergency lever 121, and the driving unit 14 drives the latch unit 11 to move to the locking state by dialing the locking input shaft 114. The fixed shaft link 112 is rotatably connected to the lock cylinder housing 151 through a third rotating shaft 1121, the moving shaft link 113 is rotatably connected to the fixed shaft link 112 through a fourth rotating shaft 1131, the locking input shaft 114 is located on a side of the third rotating shaft 1121 away from the first rotating shaft 1112, and the fourth rotating shaft 1131 is located on a side of the third rotating shaft 1121 away from the stop block 122.

The electric automobile rear door absorption lock 10 further comprises an auxiliary connecting rod 115, one end of the auxiliary connecting rod 115 is rotatably connected with the stop block 122, and the other end of the auxiliary connecting rod 115 is rotatably connected with the first end of the movable shaft connecting rod 113. The second end of the moving shaft connecting rod 113 is used for pushing the locking block 111 so that the locking block 111 rotates.

When the driving unit 14 drives the latch unit 11 to lock, the driving unit 14 moves the locking input shaft 114 in a direction away from the emergency lever 121, the fixed shaft link 112 rotates relative to the lock housing 151 with the third rotating shaft 1121 as a rotating axis, the movable shaft link 113 rotates relative to the fixed shaft link 112 with the fourth rotating shaft 1131 as a rotating axis, and the second end of the movable shaft link 113 can gradually abut against the locking piece 111 and gradually move the locking piece 111 to a position where the locking state is located in the process of rotating relative to the fixed shaft link 112 due to the existence of the auxiliary link 115. For example, when the moving axis link 113 pushes the lock block 111 at an angle as shown in fig. 5, the lock block 111 rotates clockwise.

Specifically, in one embodiment, as shown in fig. 3 and 4, the contact end 1431 is located between the panic lever 121 and the lock input shaft 114 in the axial direction of the lead screw 142. When the motor 141 is operated, the interference end 1431 moves along the axial direction of the screw rod 142 to push the emergency lever 121 or the locking input shaft 114.

As shown in fig. 5, a first abutting portion 1113 and a second abutting portion 1114 are disposed on a side of the locking block 111 close to the stopping block 122, the second abutting portion 1114 is located on a side of the first abutting portion 1113 close to the locking notch 1111, and a stopping portion 1222 is disposed on a side of the stopping block 122 close to the locking block 111. When the electric automobile rear door latch 10 is in the half-locked state, the stopping portion 1222 abuts against the first abutting portion 1113 to prevent the locking block 111 from being switched to the unlocked state, and the locking block 111 is prevented from rotating in the counterclockwise direction at the angle shown in fig. 5. When the electric automobile rear door latch 10 is in the locked state, the stopping portion 1222 abuts against the second abutting portion 1114 to prevent the lock block 111 from being switched to the unlocked state, and the lock block 111 is prevented from rotating in the counterclockwise direction at the angle shown in fig. 5.

When the lock rod enters the lock groove 1514 and the lock notch 1111, as the lock rod continues to push into the lock groove 1514, the lock block 111 is pushed to rotate to a half-lock state, at this time, the stopping portion 1222 of the stopping block 122 abuts against the first abutting portion 1113, and under the condition that the stopping block 122 does not release the stopping of the lock bolt, the lock block 111 cannot rotate in the unlocking direction.

When the electric rear door latch 10 is in the half-locked state, the driving unit 14 is operated to push the latch input shaft 114, so that the latch 111 continues to rotate clockwise to the latched state at the angle shown in fig. 5.

Specifically, for example, in one embodiment, a half-lock detector is disposed in the lock tail housing 152, and when the electric rear door lock 10 is in the half-lock state, the lock block 111 triggers the half-lock detector, and the half-lock detector is electrically connected to the driving unit 14. Therefore, when the electric rear door latch 10 is in the half-locked state, the driving unit 14 operates according to the signal detected by the half-lock detector, so that the locking block 111 continues to rotate to the locked state.

Further, in an embodiment, a locking detection member and a full-locking detection member 16 are further disposed in the lock tail housing 152, when the electric rear door latch 10 of the automobile is in the locking state, the stop block 122 triggers the locking detection member and the lock block 111 triggers the full-locking detection member 16, and both the locking detection member and the full-locking detection member 16 are electrically connected to the driving unit 14.

As the electric automobile tail gate lock 10 continues to switch from the half-lock state to the lock state, the stopping portion 1222 of the stopping block 122 gradually changes from contacting with the first abutting portion 1113 to contacting with the second abutting portion 1114, and only when the stopping portion 1222 completely abuts with the second abutting portion 1114 to lock the lock block 111, the locking detection member is triggered, and at the same time, the full-lock detection member 16 is triggered, which serves as a signal indicating that the electric automobile tail gate lock 10 is in the lock state, and the driving unit 14 may stop the pushing action of the lock input shaft 114. The situation that the automobile tail gate electric suction lock 10 is not sucked is avoided. The non-attraction here means that the stopping portion 1222 does not completely abut against the side of the second abutting portion 1114 close to the locking notch 1111, so that the locking piece 111 can rotate in the counterclockwise direction at the angle shown in fig. 5.

Specifically, the half-lock detection member may be a hall sensor, the locking detection member may be a hall sensor, and the full-lock detection member may be a hall sensor.

If the locking needs to be released, the driving unit 14 is required to drive the emergency lever 121 to move, or the manual shifting element 13 is manually shifted to push the emergency lever 121, so that the stopping block 122 rotates, the stopping block 1222 is separated from the second abutting portion 1114, and the lock block 111 can be rotationally switched to the unlocking state under the driving of the lock rod.
