The method of use of this example is as follows:

as shown in fig. 1 to 9, when the sliding door electric control lock is installed, a lock box 1 is arranged on a vehicle sliding door (not shown), a lock catch 12 is arranged on a vehicle door frame (not shown) at a position corresponding to the lock box 1, and a control end of an electric pull rod 10 is electrically connected with a vehicle electric control system.

During the sliding door locking, it is spacing with the inner wall butt that lock box 1 corresponds the side to dial the left side of 4 lower parts of board, it rotates along clockwise to prevent to dial board 4, the lateral wall butt of the corresponding position of arc portion 31 and the 5 middle part left ends of control panel, electric pull rod 10 is in the state of stretching out, the cell wall butt that axle sleeve 7 and transmission draw-in groove 30 correspond the position, locking portion 28 is spacing with the vertical section butt of first step 25, it rotates along counter-clockwise to prevent latch hook 6, make 23 joints of lock post fix in open slot 24, the both ends of lock post 23 still are located two logical grooves 19 respectively, guarantee that lock box 1 is in the locking state.

As shown in fig. 1 and 6, when the sliding door is opened by using a key or a knob 16, the lock cylinder 2 drives the toggle plate 4 to rotate in the counterclockwise direction, so that the right side wall of the lower part of the arc-shaped part 31 abuts against the side wall of the left end of the middle part of the control plate 5, in the process, the arc radius of the arc-shaped part 31 gradually changes, the control plate 5 is pushed to rotate in the counterclockwise direction by the abutment, the locking part 28 is separated from the vertical section of the first step 25 in the rotating process, the locking hook 6 is not prevented from rotating in the counterclockwise direction any more, the sliding door is pulled outwards, the locking hook 6 is pushed by the locking column 23 to rotate in the counterclockwise direction, the locking column 23 is moved out of the through groove 19 and separated from the; afterwards, when the latch hook 6 continues to rotate in the counterclockwise direction under the elastic force action of the latch hook torsion spring 13, the latch hook recedes from the inner wall of the corresponding end of the slot 20 and abuts against the inner wall, so that the latch hook recedes from the slot 20.

After the sliding door is opened, the key and the knob 16 are loosened, the poking plate 4 rotates and resets along the clockwise direction under the action of the elastic force of the poking plate torsion spring 3, and the left side of the lower part of the poking plate 4 is abutted and limited with the inner wall of the corresponding side of the lock box 1; in this process, along with the arc radius change of arc portion 31, make control panel 5 break away from the terminal surface that arc portion 31 corresponds the end gradually, locking portion 28 rotates thereupon and with the oblique section 27 butt of transition, it is spacing with the corresponding position butt of lock box 1 upper end inner wall of lock hook torsional spring 13, under the spacing prerequisite of lock hook 6, control panel 5 also keeps motionless at the current position, lock box 1 is in the state of opening.

When closing the sliding door, lock box 1 removes to hasp 12 along with the sliding door, and make the cell wall of open slot 24 and the lateral wall butt of lock post 23, promote the position when latch hook 6 rotates the locking state along clockwise, in this process, locking portion 28 breaks away from with oblique section 27 of transition, the elastic force of control panel torsional spring 14 makes control panel 5 rotate along clockwise, locking portion 28 earlier with the horizontal segment butt of second step 26, when latch hook 6 rotated to target in place, locking portion 28 breaks away from with the horizontal segment of second step 26, and spacing with the vertical section butt of first step 25, thereby make lock box 1 be in the locking state.

As shown in fig. 1 and 7, when the vehicle electronic control system is used to open the sliding door, the vehicle electronic control system sends a command to the electric pull rod 10 to retract the output end of the electric pull rod 10, the sliding bar 8 moves rightwards along with the retracting movement and drives the guide post 11 to horizontally slide rightwards in the strip-shaped groove 29, the shaft sleeve 7 abuts against and pushes the control board 5 to rotate anticlockwise in the moving process, the locking part 28 is separated from the vertical section of the first step 25 in the rotating process, the sliding door is pulled outwards, the locking post 23 moves out of the through groove 19 and is separated from the open groove 24 to open the sliding door, then, the locking hook 6 rotates and abuts against and limits the inner wall of the corresponding end of the locking hook abdicating groove 20, and the locking part 28 abuts against and limits the transition inclined section 27, so that the lock box 1 is kept in an; then, the vehicle electric control system sends an instruction to the electric pull rod 10, so that the output end of the electric pull rod 10 drives the sliding strip 8 to extend leftwards, and drives the guide post 11 to horizontally move leftwards for resetting, and the control panel 5 and the lock hook 6 are both kept still; when the sliding door is closed, the lock box 1 moves towards the lock catch 12 along with the sliding door, the groove wall of the open groove 24 is abutted to the outer side wall of the lock column 23, the lock hook 6 is pushed to rotate and reset along the clockwise direction, the locking part 28 is separated from the transition inclined section 27, the control panel 5 is rotated and reset along the clockwise direction by the elastic force of the control panel torsion spring 14, the corresponding position of the groove wall of the transmission clamping groove 30 is abutted to the shaft sleeve 7, and the lock box 1 restores the locking state.

When the sliding door is closed, if the sliding door is not closed tightly, a gap is left between the sliding door and a door frame of a vehicle body, at the moment, after the locking part 28 is separated from the transition inclined section 27, the sliding door cannot move forward to a included angle between the horizontal section of the second step 26 and the vertical section of the first step 25 and is abutted against the horizontal section of the second step 26, namely, the position of the control panel 5 in the locking state cannot be recovered, the sliding door is pulled outwards, the locking part 28 is abutted against the vertical section of the second step 26 for limiting, and the sliding door cannot be pulled open; after the lock box 1 is opened, the lock core column 2 resets and drives the toggle plate 4 to reset, and at the moment, the electric pull rod 10 is not started to enable the sliding strip 8 to be in an extending state, therefore, after the toggle plate 4 resets, a gap is reserved between the upper portion of the arc-shaped portion 31 and the side wall of the left end of the middle portion of the control panel 5, a gap is also reserved between the shaft sleeve 7 and the groove wall of the transmission clamping groove 30, at the moment, only the sliding door needs to be pushed inwards, the lock column 23 is enabled to abut against the groove wall of the open groove 24, the lock hook 6 is driven to rotate in the clockwise direction, the locking portion 28 continues to rotate to the position of the first step 25 and is limited by abutting against the vertical section of the first step 25, namely, the control panel 5 is enabled to return to the position when the locking state, at the moment, the left end of the middle portion of the control panel 5 abuts against the corresponding position.

The utility model discloses do not describe the part unanimously with prior art, do not describe herein any more.

The above is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings are directly or indirectly applied to other related technical fields, all the same principle is within the patent protection scope of the present invention.
