Example one
An automobile tail gate lock comprises a lock shell 1 and, integrated inside the lock shell 1: a locking mechanism for implementing a basic locking function, a snow load assembly for implementing a snow load function, and a signal assembly for implementing a signal indication function. The locking mechanism is composed of a motor 10, a worm 11, a gear 12, a snow carrying rod 13, a locking claw 14 and a clamping plate 15, the motor 10 is connected with the worm 11 in an output mode, the end limiting position of the worm is matched with a shaft sleeve 16, the shaft sleeve 16 is installed on a lock shell, the worm 11 is in meshing transmission with the gear 12, a first gear driving lever 12.1 and a second gear driving lever 12.2 are arranged on the gear 12, and the two gear driving levers and a gear shaft are in central symmetry. When the electric starting device is electrically started, the motor 10 drives the worm 11, the worm 11 drives the gear 12 to rotate, and the gear 12 rotates and simultaneously drives the first gear shifting lever 12.1 and the second gear shifting lever 12.2 thereon to rotate. During the rotation of the gear 12, the first gear lever 12.1 and the second gear lever 12.2 alternately engage with the recess 13.1 at the end of the snow rod 13 to drive one end of the snow rod 13 to swing in a predetermined direction. The bottom of the snow bar 13 is linked with the locking pawl 14 through the associated structure of the second end, so that when the snow bar 13 swings in the unlocking direction, the locking pawl 14 can be driven to be disengaged from the clamping plate 15 on one side, and unlocking is achieved.
Under the circumstances such as tail-gate gravity is great, sealed counter-force is not enough, electronic opening back, still unable direct unblock, then need start snow at this moment and carry the function. The snow load assembly of the embodiment comprises a snow load rod 13 linked with a locking claw 14, a first convex rib 15.1 and a second convex boss 15.2 which are arranged on preset positions of a clamping plate 15, wherein the snow load rod 13 is a functional integrated part, and on one hand, the snow load rod is linked with the locking claw 14 through a related structure 13.2 at the bottom of the snow load rod to drive the locking claw 14 to move so as to realize a basic unlocking function; on the other hand, the snow-carrying function is realized by the linkage of a laterally extending elastic arm 13.3 and the clamping plate 14. The elastic arm 13.3 has a fastening slot 13.3b for fastening and adapting to the first rib 15.1 and an abutting end 13.3a for abutting against the first rib 15.1.
The snow load function is accompanied by the following processes of electric starting:
1. snow-loaded trigger
Under the full locking state, the locking pawl is meshed with the clamping plate, and the catching groove of the elastic arm on one side of the snow carrying rod is completely locked on the first convex rib. When electronic opening, gear drive snow carries the pole action, the elastic arm slides along first protruding muscle under the dragging of snow year pole, meanwhile, the pawl with snow year pole linkage rotates to the unblock direction, snow carries the pole to continue to drag the elastic arm, pop out from first protruding muscle until its catching groove, cause the conflict end of its tip to contradict in the avris of first protruding muscle, this is snow and carries the trigger position, cardboard and pawl throw off the meshing completely this moment, can rotate the cardboard through external force, realize unblanking in order to overcome gravity.
2. Relieving snow load
The cardboard rotates and opens the in-process, and the conflict end of elastic arm slides along the avris of first protruding muscle always, and the cardboard continues to rotate until the tip that breaks away from first protruding muscle and along with snow year pole rigid arm 13.4 and cardboard second boss looks butt, reaches cardboard full open position, for the complete position of relieving of snow year this moment.
3. Snow load reposition
The cardboard is locking the in-process again, and snow carries the fourth end rigid arm of pole to slide downwards along the avris of second protruding muscle, when snow carries the third end of pole cunning to the tip of first protruding muscle, the catching groove of elastic arm lock again completely in first protruding muscle and fourth end simultaneously first directly support on the second protruding muscle again, the cardboard continues the gyration, resets to the initial position of full lock until the elastic arm, and the snow carries at this moment and also is in the state before the snow carries and triggers.
The signal assembly comprises a signal switch arranged on the lock shell, the signal switch is arranged on one side of the snow load rod, and the signal indicating function of each state is realized through a cam structure at the tail end of the locking pawl.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
