Detailed Description
As shown in fig. 1-3, the full-automatic automobile tail door lock comprises a lock case (not shown), a large bolt 5 and a small bolt 6, wherein the large bolt 5 and the small bolt 6 are both rotatably arranged on the lock case, the large bolt 5 is provided with a lock slot 50, the large bolt 5 hooks a lock hook on an automobile through the lock slot 50, and the large bolt 5 can be matched with the small bolt 6 to realize three functions of unlocking, half locking and full locking. Therefore, as shown in fig. 4, the large lock tongue 5 has a full lock stopper surface 52 at a position adjacent to the lock groove 50, the large lock tongue 5 has a half lock stopper surface 51 at a position away from the lock groove 50, and the small lock tongue 6 has a lock stopper portion 60. As shown in fig. 4, when the large lock bolt 5 is not rotated, the lock groove 50 of the large lock bolt 5 is on the outside, and is in the unlocked state; as shown in fig. 5, when the large bolt 5 rotates inwards by a half, the limit part 60 of the small bolt 60 acts on the half-lock limit surface 51; as shown in fig. 6, when the large lock tongue 5 rotates inward a distance, the stopper 60 of the small lock tongue 6 acts on the full lock stopper surface 52.
The locking action of big spring bolt 5 and little spring bolt 6 is all by motor 1 driven, motor 1 installs on the lock shell, still install well straight-teeth gear 2 in the lock shell, motor 1 is connected with the transmission of well straight-teeth gear 2, as shown in figure 1, the lower extreme of well straight-teeth gear 2 is equipped with stirs little spring bolt 6 pivoted shifting block 9, well straight-teeth gear 2 meshes with big straight-teeth gear 3, big straight-teeth gear 3 is connected with stirring big spring bolt 5 pivoted and dialling arm 4 transmission, big spring bolt 5 is connected with big spring bolt return torsional spring, little spring bolt 6 is connected with little spring bolt return torsional spring. When the trunk lid needs half-locking, the motor 1 rotates positively to drive the middle straight gear 2 to rotate, the shifting block 9 at the lower end of the middle straight gear 2 shifts the small spring bolt 6 to rotate, the middle straight gear 2 rotates and simultaneously drives the large straight gear 3 to rotate, the shifting arm 4 connected with the large straight gear 3 shifts the large spring bolt 5 to rotate, and thus the large spring bolt 5 enters a half-locking position, namely the limiting part 60 of the small spring bolt 6 acts on the half-locking limiting surface 51 of the large spring bolt 5; when the trunk lid needs to be fully locked, the motor 1 rotates forwards again to complete the same steps, so that the limiting part 60 of the small bolt 6 acts on the full-locking limiting surface 52 of the large bolt 5, and full locking is realized.
Certainly, when the tail door lock is in an unlocking state, a half-locking state and a full-locking state, the motor 1 needs to be controlled to stop working, and therefore the tail door lock is also provided with an unlocking limit switch capable of sensing unlocking, a half-locking limit switch capable of sensing half-locking and a full-locking limit switch capable of sensing full-locking, and the unlocking limit switch, the half-locking limit switch and the full-locking limit switch are all electrically connected with the motor 1; of course, the three limit switches only need to act with corresponding parts and can respectively sense three states of the lock, and when the limit switches act with the parts, the motor 1 stops rotating, so that the small bolt 6 and the large bolt 5 are in the current states.
When the lock is to be unlocked, the motor 1 rotates reversely, the large straight gear 3 rotates reversely, so that the shifting arm 4 retreats, and the large lock tongue 5 returns under the action of the large lock tongue return torsion spring; the motor 1 rotates reversely, the middle straight gear 2 also rotates reversely, the shifting block 9 also rotates reversely, and the shifting block 9 does circular motion along with the middle straight gear 2, so the shifting block 9 can be clamped by the small bolt 6 without the help of an auxiliary structure, and the reverse rotation cannot be realized. Therefore, the invention also provides a shifting block return assembly on the small bolt 6, as shown in fig. 2, the shifting block return assembly comprises a rotating plate 8 rotatably arranged on the small bolt 6, a small straight gear 7 meshed with the middle straight gear 2 and a semicircular buffer block 70, the semicircular buffer block 70 is connected to the lower end of the small straight gear 7, the rotating plate 8 is provided with a baffle 81, the semicircular buffer block 70 acts on the baffle 81, the rotating plate 8 is connected with a rotating plate return torsion spring, and the rotating plate 8 is provided with a shifting part 80 acting with the shifting block 9. When the motor 1 rotates forwards and is locked, the shifting block 9 acts on the shifting part 80 of the rotating plate 8, so that the small bolt 6 is driven to rotate through the rotating plate 8; when the motor 1 is reversely rotated to unlock, the middle straight gear 2 drives the small straight gear 7 to rotate, the small straight gear 7 drives the semicircular buffer block 70 to rotate, the arc surface of the semicircular buffer block 70 acts on the baffle 81 of the rotating plate 8 firstly, the shifting part of the rotating plate 8 is positioned at the outer side, the shifting block 9 cannot be blocked by the rotating plate 8 when returning, the shifting block 9 returns normally, and the rotating plate 8 returns under the action of the rotating plate return torsion spring after the arc surface of the semicircular buffer block 70 passes.
Of course, in order to make the motor 1 drive the middle straight gear 2 to rotate, the invention is connected with a worm 10 at the output shaft of the motor 1, the worm 10 is meshed with a worm wheel 11, and the upper end of the middle straight gear 2 is connected with the center of the worm wheel 11. Through the connecting structure, the motor 1 can drive the middle straight gear 2 to rotate.
