Specifically, the locating block is disposed proximate the recessed end of the connecting rod 40. The gear face of the first gear 30 is further provided with a fixed block, one end of the first torsion spring 50 is fixed on the connecting rod 40, the other end of the first torsion spring is fixed on the fixed block, after the fixed block is arranged, one end of the first torsion spring is fixed on the fixed block and can be in close contact with the fixed block, welding or other connecting modes are not needed, and the first torsion spring is convenient to install and detach. Specifically, the positioning block and the fixing block are integrated, the positioning block and the fixing block are semicircular members 101 fixed on the gear surface of the first gear 30, one end of the semicircular members 101 corresponds to the fixing block and is fixed with the first torsion spring 50, the other end corresponds to the positioning block, and the positioning block is in close contact with the connecting rod 40 when the groove 41 is separated from the protrusion 61. In the present embodiment, the end of the semicircular member 101 fixed to the first torsion spring 50 may be in close contact with the end of the first torsion spring 50.
In the present embodiment, the protrusion 61 is cylindrical, the groove 41 is a "V" shaped groove, the bottom of the groove is an arc having the same radius as the protrusion 61, specifically, the protrusion 61 is integral with the grasping rod 60, and the arc is designed as a quarter arc.
The emergency release lever 110 is rotatably mounted on the first rotation shaft 20, one end of the emergency release lever 110 is connected with a mechanical driving mechanism, and the other end is provided with a toggle claw 111, and the mechanical driving mechanism is mounted outside the lock case.
In this embodiment, the mechanical driving mechanism is driven by a manual or pulling wire, and the emergency release lever 110 is provided with a bending section 112 bent inwards towards one side of the connecting rod 40, and the bending section 112 is smoothly transited through an arc.
The pawl 80 is rotatably mounted on the lock housing, the coil of the third torsion spring 90 is sleeved on the rotating shaft of the pawl 80, one end of the third torsion spring 90 is fixed on the pawl 90, and the other end is fixed on the lock housing.
The lock tongue 200 is rotatably installed on the lock case, two gear teeth 210 and 220, a toggle block 230 and a hook 240 are provided on the outer edge of the lock tongue 200, and the opening of the hook 240, the gear teeth 220, the gear teeth 210 and the toggle block 230 are sequentially provided along the rotation direction of the lock tongue 200 from the half-lock state to the full-lock state, and the angle between the two gear teeth 210 and 220 enables the hook 240 to hook the lock frame from half to full. The rotating shaft of the lock tongue 200 is sleeved with a fourth torsion spring 250, one end of the fourth torsion spring 250 is fixed on the lock tongue 200, and the other end is fixed on the lock shell. In this embodiment, the lock tongue 200 is provided with the bump 260, and one end of the fourth torsion spring 250 is fixed on the bump 260, specifically, the bump 260 is disposed at a position, so that one end of the fourth torsion spring 250 is in close contact with the bump 260, without welding or other connection with the bump 260.
The pawl 80 and the tongue 200 constitute a ratchet pawl mechanism, and the third torsion spring 90 and the fourth torsion spring 250 allow the pawl 80 and the tongue 200 to be in close contact all the time. When the pawl 80 is not engaged with either of the two gear teeth 210 and 220, the lock tongue is in an unlocked state, when the pawl 80 is engaged with the gear tooth 210 near the toggle block 230, the lock tongue 200 is in a half-locked state, and when the pawl 80 is engaged with the gear near the hook 240, the lock tongue 200 is in a full-locked state.
When the latch bolt is unlocked to the half lock, the rotation of the latch bolt 200 pushes the pawl 80 to rotate in the opposite direction to the latch bolt 200, the latch bolt 200 rotates clockwise when seen in the direction of fig. 1, the pawl 80 rotates counterclockwise, and when the pawl 80 slides across the back of the teeth of the gear teeth 210, the pawl 80 rotates clockwise when seen in the direction of fig. 1, by reversing under the elastic force of the third torsion spring 90, so that the pawl 80 is engaged with the gear teeth 210. When the lock tongue 200 is in the half-lock state to the full-lock state, the lock tongue 200 rotates clockwise when seen in the direction of fig. 1, the pawl 80 is pushed to rotate anticlockwise, and when the pawl 80 is scratched behind the teeth of the gear teeth 220, the pawl 80 rotates clockwise when seen in the direction of fig. 1 under the action of the elastic force of the third torsion spring 90, so that the pawl 80 is meshed with the gear teeth 220, and the lock tongue is in the full-lock state. The angle through which the locking bolt 200 rotates from the half-lock to the full-lock state is the same as the angle between the two gear teeth 210 and 220.
The positional relationship between the grasping rod 60 and the latch bolt 200 is such that the grasping rod 60 is separated from the striking block 230 when the full locking is not performed, and the convex end of the grasping rod 60 contacts the striking block 230 after the connecting rod 40 pushes the grasping rod 60 to rotate during the full locking is performed, and the maximum angle by which the grasping rod 60 pushes the striking block 230 to rotate is equal to the angle between the two gear teeth 210 and 220.
When the trunk/door is in the semi-locked condition, pawl 80 engages gear 210 as shown in FIG. 1. The external controller controls the motor to rotate, and drives the first gear 30 to rotate through the transmission unit 10, thereby driving the connection rod 40 to move, so that the groove 41 on the connection rod 40 contacts the protrusion 61 on the grasping rod 60. Before the groove 41 on the connecting rod 40 contacts the protrusion 61 on the grasping rod 60, the connecting rod 40 is stationary with respect to the first gear 30, and after the contact, the groove 41 on the connecting rod 40 rotates around the protrusion 61 while pushing the grasping rod 60 to rotate, so that the protruding end of the grasping rod 60 contacts the toggle block 230 of the lock tongue 200. The motor continues to rotate, the connecting rod 40 continues to push the grasping rod 60 to rotate, the grasping rod 60 pushes the toggle block 230 to rotate so that the lock tongue 200 rotates, the angle by which the grasping rod 60 pushes the lock tongue 200 to rotate is the same as the angle between the two gear teeth 210 and 220, so that the pawl 80 is separated from the gear teeth 210 and strokes over the rear engaging gear teeth 220 from the tooth backs of the gear teeth 220, and the lock tongue 200 reaches the full locking position. The external controller then controls the motor to rotate reversely, and drives the first gear 30 to rotate reversely through the transmission unit 10 until the groove 41 of the connection rod 40 is separated from the protrusion 61 of the grasping rod 60, and the state is restored to the half-lock state. Specifically, the motor forward rotation and reverse rotation control the angle through which the first gear 30 rotates to be the same.
In the process of performing the full lock, after the first gear 30 rotates to drive the connecting rod 40 to move, the groove 41 of the connecting rod 40 contacts and mates with the protrusion 61 of the grasping rod 60, as shown in fig. 3; at this time, when the power-off condition occurs, the first gear 30 stops rotating, the mechanical driving mechanism drives the emergency unlocking lever 110 to rotate towards the connecting rod 40, the emergency unlocking lever 110 contacts with the blocking post 42, the emergency unlocking lever 110 drives the connecting rod 40 to be separated from the grasping lever 60, and the grasping lever 60 is reset under the acting force of the second torsion spring 70 so as to release the toggle block 230, as shown in fig. 4; simultaneously, the poking claw 111 is in contact with the pawl 80, the poking claw 111 pushes the pawl 80 to rotate anticlockwise, the two gear teeth 210 and 220 are separated from the pawl 80, and the lock tongue 200 reaches an unlocking state, as shown in fig. 5; after the mechanical driving mechanism is released, the force on the emergency release lever 110 is removed and the emergency release lever 110 is restored to the original state as shown in fig. 6.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
