Closing assisted electric lock for opening of automobile
The invention relates to a closing assisted electric lock for the opening of an automobile, that comprises: a bolt ( 5 ) including first ( 19 ) and second ( 20 ) notches, said bolt ( 5 ) interacting with a strike and being capable of rotating between an open position, a position closed at the first notch of the lock and a position closed at the second notch of the lock; a pivoting ratchet ( 13 ) capable of interacting with said bolt ( 5 ) for preventing the rotation thereof ( 5 ) into a closed position at the first and second notches of the lock; a bolt ( 5 ) driving lever for rotatingly driving the bolt ( 5 ) between the closed position at the first notch and the closed position at the second notch of the lock; characterized in that the driving lever ( 9 ) includes a protrusion ( 37 ) provided so that said bolt ( 5 ) is capable of pivoting the lever ( 9 ) when said bolt ( 5 ) rotates from the open position to the closed position at the second notch of the lock.
1. A closing-aid electric lock for an opening element of a motor vehicle comprising:
a bolt comprising a first catch and a second catch, wherein the bolt interacts with a strike and rotates between an open position, a closed position at the first catch, and a closed position at the second catch of the lock;
a pivoting pawl that interacts with said bolt in order to prevent a rotation of said bolt in the closed position at the first and at the second catch of the lock; and
a lever for operating said bolt in order to rotate said bolt between the closed position at the first catch and the closed position at the second catch of the lock, wherein said lever comprises a first arm configured to connect to an electric actuator, and a second arm supporting a protuberance and for interacting with an actuation member secured in rotation to said bolt, wherein the protuberance is formed in a first branch forming a fork with a second branch at the free end of the second arm of said lever, and wherein the actuation member comprises an excrescence that interacts with the fork,
wherein the fork is arranged so that said excrescence causes said lever to pivot when said bolt turns from the open position to the closed position at the first catch of the lock in order to operate the lever in a position engaged with the bolt, placing the lever in the effective path of the actuator of the lever,
wherein the first branch of the fork is pivoted by the excrescence when the bolt turns from the open position to the closed position at the first catch of the lock,
wherein the second branch of the fork rotates the excrescence between the closed position at the first catch and the closed position at the second catch of the lock, and
wherein the lever for operating said bolt is disengaged from the bolt when the lock is in the open position.
2. The lock as claimed in claim 1 , further comprising: a first position sensor capable of determining the closed position at the second catch of the lock.
3. The lock as claimed in claim 2 , wherein said first sensor is placed at the operating lever, so as to be activated when the operating lever has pivoted from the closed position at the first catch to the closed position at the second catch of the lock.
4. The lock as claimed in claim 3 , further comprising: a second position sensor capable of determining an active position of retention of said bolt by said pawl.
5. The lock as claimed in claim 4 , wherein said second sensor is placed at a driver of said pawl so as to be activated when said pawl is in the active position of retention of said bolt.
6. The lock as claimed in claim 5 , wherein the first and second position sensors are connected to a processing unit, capable of controlling the driving of said bolt by the operating lever when the second position sensor of the pawl is activated and the first sensor of said lever is deactivated, until said first sensor is also activated.
7. A functional lock-actuator assembly comprising: a lock as claimed in claim 1 and the electric actuator connected to said lever via a drive cable.
