The working process of the invention comprises the following steps:
the invention relates to a power-accumulating type electric door lock switch, which has the working principle that:
Door opening state
As shown in fig. 3, the locking body 130 is in the unlocking position, the boss 132 of the locking body 130 is not in contact with the unlocking torsion spring 220, the unlocking torsion spring 220 is in a free state, the unlocking torsion spring 220 does not act on the slider 160, the slider 160 moves in the direction D under the action of the locking plate 140, and the operation plate 150 is inserted into the slider 160 under the action of the return spring 230 to block the movement of the slider 160 in the opposite direction D. As shown in fig. 4, the positioning pin 141 of the locking plate 140 is now in the a position of the locking body heart-shaped structure.
2. Locking action
As shown in fig. 4 and 5, when the door is closed, the door bolt is inserted into the bolt hole along the direction a to drive the locking body 130 to rotate along the direction B against the locking torsion spring 200, and as shown in fig. 6, the positioning needle 141 of the locking plate 140 moves along the groove of the heart-shaped structure 131 of the locking body 130, and moves from the position a to the position B, after passing over the position B, the door closing action disappears, the locking body 130 rotates under the action of the locking torsion spring 200, and the locking plate 140 moves from the position B to the position c under the action of the tension spring 170, the positioning needle 141 contacts with the heart-shaped structure 131 of the locking body 130, so that the locking body 130 is prevented from continuing to rotate, and the locking function is realized.
In addition, when the locking body 130 rotates, the boss 132 of the locking body 130 also rotates together, driving the unlocking torsion spring 220 to rotate by a certain angle. When the lock body 130 reaches the lock position, the unlocking torsion spring 220 generates a sufficient torsion force to act on the slider 160. Since the operation plate 150 is inserted on the slider 160 to prevent the slider 160 from moving in the opposite direction of D, the slider 160 does not apply force to the locking plate 140, and the entire locking module can be operated normally.
Third, electric unlocking action
As shown in fig. 7, when the door lock is in a locked state, the electromagnetic coil 191 is energized, the piston 192 pulls the operation plate 150, the operation plate 150 slides out of the groove of the slider 160, the slider 160 moves in the F direction under the action of the unlocking torsion spring 220, the locking plate 140 is pushed to move in the F direction, the positioning needle 141 of the locking plate 140 slides out of the locking body 130, and the locking body 130 rotates under the action of the locking torsion spring 200, so that the unlocking action is realized.
Contrast of the magnitude of the driving force required for unlocking:
Scheme of application number CN 105806008B: assuming that the locking body is under force F, the friction coefficient of the locking plate and the locking body is 0.2, the driving force of the driving mechanism is at least 0.2 x F.
The scheme of the invention is as follows: assuming that the locking body 130 is subjected to force F, the friction coefficient of the locking plate 140 and the locking body 130 is 0.2, the driving force of the driving mechanism is at least 0.2 x F; if the force to unlock the torsion spring 200 when the door is closed is set to be above 0.2F n, then the force acting on the slider is also above 0.2F n, and the coefficient of friction of the slider 160 and the operating plate 150 is also 0.2, then the driving force of the driving mechanism needs only 0.2 x f=0.04F, which is much smaller than the force required by CN 105806008B.
Fourth, manual unlocking
In the locked state, as shown in fig. 8, the latch continues to move in the direction a, and as shown in fig. 9, the positioning pin 141 of the locking plate 140 moves along the slot of the heart-shaped structure 131 of the locking body 130, and moves from the c position to the d position, and after the locking body passes over the d position, the locking body 130 rotates under the action of the locking torsion spring 200 after the action force disappears, so that the positioning pin returns to the a position from the d position, thereby realizing the unlocking and door opening functions.
The above embodiments are illustrative of the present invention, and not limiting, and any simple modifications of the present invention fall within the scope of the present invention.
