The motor can be energized in forward and reverse directions, so that the drag arm 7 engaged with the input gear 5 can also perform a rotational movement leftward/rightward.
The half-lock signal switch 13 not only can be used as a pull-in start signal, but also has the function of a door opening indication signal.
The working principle of the self-priming self-opening automobile tail door lock provided by the utility model is as follows:
electric unlocking: the door lock is in under full lock or half lock state, and after the driver triggered electronic opening button, automobile body BCM adds the electricity for electronic module, and electronic module adds the clockwise rotation of back trailing arm 7 with electricity, drives and opens arm 8 and pawl 9 and moves right (opening direction) together, moves to certain position back pawl 9 and wraps and moulds cardboard 13 and break away from the meshing, wraps and moulds cardboard 13 and realize restoring to the throne under the effect of cardboard reset spring 15 is moulded to the package. When the locking claw 9 is reset, the locking claw reset switch 10 is synchronously triggered to enable the reset signal to generate level change, the BCM of the vehicle body supplies reverse voltage to the electric module to reset the dragging arm 7, when the dragging arm 7 is reset, the electric switch reset switch 6 is synchronously triggered to enable the reset signal to generate level change, the BCM of the vehicle body immediately powers off the electric module after detecting the level change, and finally the dragging arm 7 returns to the initial position to complete all actions of electric starting.
Electric suction: after the driver triggers the electric door closing key, the door of the automobile makes the door lock in a half-locking state under the self gravity, and the plastic-coated clamping plate 13 synchronously triggers the half-locking signal switch 13 to make the signal of the half-locking signal switch change. At this time, the BCM of the vehicle body powers on the electric module, the dragging arm 7 rotates anticlockwise after the electric module powers on, the plastic coated clamping plate 13 is driven to move leftwards (in the locking direction), the locking claw 9 and the plastic coated clamping plate 13 start to be meshed after the electric module moves to a certain position, and the locking claw 9 is reset under the action of the locking claw reset spring 14. When the locking claw 9 is reset, the locking claw reset switch 10 is synchronously triggered to enable the reset signal to generate level change, the BCM of the vehicle body provides reverse voltage for the electric module to enable the dragging arm 7 to reset, when the dragging arm 7 is reset, the electric sucking reset switch 11 is synchronously triggered to enable the reset signal to generate level change, the BCM of the vehicle body immediately powers off the electric module after detecting the level change, and finally the dragging arm 7 returns to the initial position to complete all actions of electric sucking.
Locking function: the vehicle body lock catch moves along the arrow direction to push the plastic-coated clamping plate 13 to rotate clockwise, when reaching a certain position, the locking pawl 9 originally put on the plastic-coated clamping plate 13 rotates clockwise around the locking pawl shaft 18 under the action of the locking pawl reset spring 14, the meshing characteristic surface 9-1 of the locking pawl is meshed with the meshing characteristic surface 14-1 of the plastic-coated clamping plate 13, the meshing realizes a half-locking function, after the half-locking position triggers a corresponding signal, the door lock executes a suction function, the plastic-coated clamping plate 13 rotates clockwise, when reaching a certain position, the meshing characteristic surface 142 of the locking pawl is meshed with the meshing characteristic surface 91 of the locking pawl 9, and the meshing realizes a full-locking function, such as a full-locking picture. From the half-locking position to the full-locking position, the engaging feature surface 71 of the dragging arm 7 is kept engaged with the engaging feature surface 14-3 of the plastic-coated clamping plate 13 until the whole sucking action is completed.
Emergency opening function: if the electric module breaks down or the whole vehicle is powered off, the electric unlocking function has the hidden trouble that the lock cannot be normally unlocked, and in order to eliminate the hidden trouble and protect the life and property safety of passengers, the emergency unlocking function becomes more important. As shown in fig. 3, it is implemented as follows: when emergency happens, a passenger can toggle the opening arm 8 (keeping the tail gate open) in the vehicle, push the tail gate in the opening direction (a gear transmission non-self-locking structure), and then the opening arm 8 and the locking claw 9 rotate together until the locking claw 9 is completely separated from the plastic-coated clamping plate 13, so that all actions of the emergency opening function are completed.
Compared with the related art, the self-suction self-opening automobile tail door lock provided by the utility model has the following beneficial effects:
the self-priming self-opening automobile tail door lock body ECU drives the driving mechanism 1, a motor 102 of the driving mechanism 1 drives a dragging arm to rotate along a certain direction, and a plastic-coated clamping plate 13 is pushed, so that the plastic-coated clamping plate 13 is meshed with a locking pawl 9 and rotates to a full-locking position; when the plastic-coated clamping plate 13 is in a full-locking state, the driving motor 102 is driven to rotate reversely through an ECU (electronic control Unit) signal of the vehicle body to drive the dragging arm 7 to rotate along the other direction, the locking claw 9 is indirectly pushed through the opening arm 8, so that the plastic-coated clamping plate 13 is disengaged from the locking claw 9 and rotates to a full-opening position; when BCM outage or circuit break down, through the instrument or hang the acting as go-between on opening arm 8, make package plastic cardboard 13 pawl 9 break away from the meshing, realize emergent the function of opening and have the function comprehensive, compact structure is reasonable small, safe and reliable, the practicality is stronger, and market potential is big, easily popularizes and applies.
