The various operating principles of the present invention are explained in conjunction with fig. 5 to 11:
the normal locking process of the invention under the control of the motor 25 is as follows:
according to the flat emergency door lock 50, the extending direction of the first poking end 1-1 in the locking poking rod 1 is adjusted by 180 degrees, the flat emergency door lock can avoid the glass lifter 30 and is arranged close to the vehicle door 31 when the motor 25 is configured, and the occupied space is small.
According to the invention, the locking deflector rod 1 is in contact connection with the unlocking pawl 10, the unlocking pawl 10 is fixedly connected with the clamping plate 2 through the first fixing pin 4, and the motor 25 drives the locking deflector rod 1 to rotate anticlockwise so as to drive the unlocking pawl 10 and the clamping plate 2 to rotate anticlockwise simultaneously, so that the locking purpose is achieved.
Because of receiving the restoring force effect of first pressure torsion spring 11 for urgent unblock driving lever 12 has an anticlockwise turning force all the time, and urgent unblock driving lever 12 is connected through pinhole interference with automatically controlled unblock driving lever 5, and then drives automatically controlled unblock driving lever 5 and has an anticlockwise turning force, makes automatically controlled unblock driving lever 5 keep constantly with cardboard 2 normally closed contact.
The normal unlocking process under the control of the motor 25 comprises the following steps:
when the motor 25 normally operates, due to the limiting effect of the long hole 9-1 of the arc-shaped linkage bar 9, when the first connecting pin 6 reaches the unlocking position, the first connecting pin is not completely contacted with the inner wall of the semicircular hole at the lower end of the long hole 9-1, so that the emergency unlocking deflector rod 12 is not needed to play a role, the motor 25 drives the first main deflector rod 27 to move through the rack 26, and the first main deflector rod 27 is contacted with and stirs the electric control unlocking deflector rod 5, so that the normal unlocking under the driving of the motor 25 can be realized.
The emergency unlocking process without the control of the motor 25 comprises the following steps:
when the motor 25 is stuck in the midway of operation, the manual pull-lock body 36 is used for starting the emergency unlocking working mode of the invention, namely the pull-lock body 36 is used for pulling the lower end of the emergency unlocking deflector rod 12 to move clockwise so as to drive the electric control unlocking deflector rod 5 to move clockwise, the position of the locking deflector rod 1 keeps the stuck position motionless because the motor 25 is stuck, the electric control unlocking deflector rod 5 moves clockwise to drive the arc-shaped linkage strip 9 to move downwards, the arc-shaped linkage strip 9 drives the unlocking pawl 10 through the first connecting pin 6 connected with the gap in the long hole 9-1, the unlocking pawl 10 does not have excessive displacement because the spacing column 2-1 is arranged on the clamping plate 2, when the notch 32 of the unlocking pawl 10 moves towards the spacing column 2-1 until the notch 32 is contacted with the spacing column 2-1, the locking deflector rod 1 does not provide locking supporting force any more, at the moment, the clamping plate 2 is released, and the locking pin 3 is driven to return clockwise, so that the purpose of emergency unlocking is achieved.
The motor 25 jamming phenomenon mainly occurs after the door lock is fully locked, and the normal unlocking cannot be realized, so the motor jamming phenomenon in the fully locked state is taken as a typical condition for the following analysis:
because the motor 25 is in a fault and is locked, the locking shift lever 1 and the electric control unlocking shift lever 5 cannot be driven to move through the motor 25, and therefore the emergency unlocking function can be started. The emergency unlocking shift lever 12 is pulled by the manual unlocking body 36 to rotate clockwise around the second fixing pin 7, and the electronic unlocking shift lever 5 is driven to rotate clockwise around the second fixing pin 7 through the contact connection with the electronic unlocking shift lever 5. At the moment, the electric control unlocking deflector rod 5 drives the arc-shaped linkage strip 9 fixedly connected through the second connecting pin 8 to generate downward tilting motion, when the arc-shaped linkage strip 9 moves downwards, the long hole 9-1 drives the unlocking pawl 10 to move around the unlocking pawl 10 and a third fixing pin on the clamping plate 2 through the first connecting pin 6, and when the maximum displacement point is reached, the unlocking pawl 10 is limited by a limit column 2-1 preset on the clamping plate 2, at the moment, the locking deflector rod 1 does not support the unlocking pawl 10 any more, namely, sufficient clearance can be generated between the unlocking pawl 10 and the locking deflector rod 1 to allow the unlocking pawl 10 to make return motion, at the moment, sufficient clearance is also formed between the electric control unlocking deflector rod 5 and the clamping plate 2 to allow the clamping plate 2 to make return motion, at the moment, no external force exists to prevent the clamping plate 2 from unlocking, and then the lock pin 3 is stirred to make return motion through a second compression torsion spring 13 preset under the clamping plate 2, i.e. to implement the unlocking procedure of the present invention.
Arrange the motor in the vertical direction in traditional lock, motor and lock composite construction occupation space in the vertical direction is great, and occupation space in the horizontal direction is less, and the motion trail that occupies glass-frame riser 30 can be invaded to the shared space position of lock installation.
The first toggle end 1-1 of the locking toggle lever 1 in the invention is extended to the left, and the motor 25 can be arranged closely to the vehicle door 31, so that the residual space can be fully utilized. Because the axial line spatial position in the vertical direction is staggered, the installation of the motor 25 does not influence the movement track of the glass lifter 30 any more, and the novel vehicle type can be better adapted without the movement interference phenomenon.
The operation of the motor 25 drives the rack 26 to move up and down according to a predetermined track, and the power of the motor 25 is transmitted to the locking deflector rod 1 and the electric control unlocking deflector rod 5 by matching the first main deflector rod 27 and the second main deflector rod 28 on the rack 26 with the first toggle end 1-1 and the third toggle end 5-1 respectively, thereby realizing the unlocking and locking of the lock body. Under this state, the automatically controlled unblock driving lever 5 produces the restoring force that makes automatically controlled unblock driving lever 5 anticlockwise rotatory because the effect of first compression torsion spring 11 to make automatically controlled unblock driving lever 5 closely laminate with cardboard 2 all the time, keep flat emergent lock 50 normal locking of money.
The unlocking state of the door lock is divided into two links which are sequentially operated, wherein the two links are respectively as follows:
when the motor 25 acquires the unlocking signal, a pre-unlocking state is achieved, namely the motor 25 runs to drive the rack 26 to move upwards to a preset position, at the moment, the lock body still keeps a locking state due to the supporting effect of the electric control unlocking deflector rod 5, the lock body is separated independently for convenience of explanation, and the time can be taken as transient processing.
The motor 25 continues to run, driving the rack 26 to continue upward until the fully unlocked position is reached. At this moment, automatically controlled unblock driving lever 5 is clockwise around the rotation center, and until no longer playing the supporting role to cardboard 2, cardboard 2 produces around the clockwise motion of center owing to the restoring force effect of the second compression torsion spring 13 of predetermineeing to it can to wait for next unblock signal to promote shutting driving lever 1 through the unblock pawl 10 that is connected with cardboard 2 and get back to original state.
Fig. 8 shows the procedure of the emergency unlocking operation of the present invention:
after the motor 25 reaches the locking position, if the lock body is locked due to the failure of the motor 25, the rack 26 is still at the moment, so that the locking deflector rod 1 is prevented from resetting, and the clamping plate 2 is prevented from resetting through the supporting function between the locking deflector rod and the unlocking pawl 10, so that the door lock cannot be unlocked. And then the lock can be unlocked through the emergency unlocking device. Utilize the manual pulling lock body 36 to stimulate urgent unblock driving lever 12, make it produce the motion of clockwise rotation, and through the mechanical linkage effect between with automatically controlled unblock driving lever 5, drive automatically controlled unblock driving lever 5 and also produce the motion of clockwise rotation, because the motion of automatically controlled unblock driving lever 5, and then drive the arc linkage strip 9 motion that is connected with it, rethread arc linkage strip 9's slot hole 9-1, drive pawl 10 and rotate around its center of rotation, when pawl 10 rotates to the extreme position, can produce the clearance between shutting driving lever 1 and the pawl 10, can not provide the holding power again promptly, cardboard 2 produces the rotation of clockwise direction because of 13 restoring force effects that compress tightly torsional spring 2 this moment, thereby the hindrance of shutting driving lever 1 has been avoided, accomplish the successful unblock process promptly.
