Background

The triggering of the automobile door lock switch means that the locking state of the side door and the back door of the automobile triggers the corresponding switch, so that the locking state information of each automobile door is transmitted to a driver, and the safety of personnel in the automobile is ensured.

According to the requirements of the regulation GB15086, door locking systems for vehicles require that the passenger compartment has at least two locking positions, namely half-lock and full-lock. In a traditional non-electric suction door lock system, a vehicle door is completely opened to a half-lock state, a trigger switch is triggered once, and the trigger switch is triggered once again from the half-lock state to a full-lock state. Therefore, when the vehicle door is in a half-locking state or a full-locking state, the trigger switch can indicate that the door lock is locked, different locking states are not distinguished, and inaccurate signals are brought to users; in the case of the half-lock state, the driving is very unsafe, so that an inaccurate signal increases the possibility of safety accidents during driving.

In the second embodiment, only the trigger position of the first switch is different from that of the first embodiment, and the rest of the components are the same as those of the first embodiment.

from a fully open state to a half-lock state, the lock tongue 21 can be cut in through the lock catch, so that the lock tongue rotates clockwise, the first protrusion is enabled to be meshed with a first gear on the lock tongue, and the first protrusion is meshed in the half-lock state under the clockwise reset force and the anticlockwise force of the first gear; the second protrusion of the signal pull rod is continuously supported by the second bolt rib, and the signal pull rod continuously triggers the second switch; the first bolt rib of the bolt also rotates along with the bolt, and when the bolt is in a half-locking state, the first bolt rib just contacts with the first switch to trigger the first switch;

from a half-locking state to a full-locking state, the transmission unit can only shift the second shifting block to enable the lock tongue to continue to rotate clockwise, so that the first protrusion is meshed with a second gear on the lock tongue, and the first protrusion is meshed in the full-locking state under the clockwise reset force and the anticlockwise force of the second gear; the pawl drives the signal pull rod to rotate, the second protrusion is also meshed into a second gear on the lock tongue, so that the signal pull rod is not contacted with the second switch any more, and the triggering of the second switch is finished; and the first lock tongue rib of the lock tongue also rotates along with the lock tongue, and is not contacted with the first switch when the first lock tongue rotates to a full-lock state, so that the triggering of the first switch is finished.

Further, the states of the pawl and the bolt are reset as follows: reset to full open mode from full lock state, can only stir through drive unit first group moves the piece, impels pawl anticlockwise rotation, and make the pawl with the spring bolt can not contact, the spring bolt receives anticlockwise reset power to reset, after the spring bolt resets and accomplishes, stop stirring first group moves the piece, the pawl receive clockwise reset power again with the spring bolt contact, the signal pull rod receive clockwise reset power again with second spring bolt muscle contact triggers the second switch, this moment first spring bolt muscle still can not with first switch contact, consequently first switch is in the state that does not trigger.

Therefore, in the first embodiment, the second switch is triggered in the fully-opened state and the half-locked state, is used for reminding a vehicle owner that the vehicle door is in the incompletely-locked state, and has potential safety hazards; the first switch is triggered only in a full-open state and is used for distinguishing signals in a half-lock state; the first switch and the second switch are not triggered any more in a full-locking state, and therefore the owner of the vehicle is not reminded any more. That is, the first switch and the second switch are triggered simultaneously in the full-open state, only the second switch is triggered in the half-lock state, and neither the first switch nor the second switch is triggered in the full-lock state. In a second embodiment, the second switch is triggered in a fully-opened state and a half-locked state, and is used for reminding a vehicle owner that the vehicle door is in an incomplete-locked state, so that potential safety hazards are generated; the first switch is triggered only in a half-locking state and is used for distinguishing a signal in a full-open state; the first switch and the second switch are not triggered any more in a full-locking state, and therefore the owner of the vehicle is not reminded any more. That is, in the present embodiment, only the second switch is triggered in the fully open state, and in the half-lock state, the first switch and the second switch are triggered at the same time, and in the fully-lock state, neither the first switch nor the second switch is triggered. The two embodiments realize different trigger signals in different locking states, and the driving safety is improved. And the three states are triggered, so that the reminding effect is realized, the problem that the switch signal is easy to be abnormal due to frequent triggering reminding is avoided, and the service life of the switch triggering mechanism is prolonged.

Preferably, in one embodiment, as shown in fig. 1 to 8, the first returning member 13 includes a first torsion spring, the second returning member 14 includes a second torsion spring, the third returning member 22 includes a third torsion spring, a coil of the first torsion spring is sleeved on the first rotating shaft 10, one end of the first torsion spring is fixed on the pawl 11, and the other end of the first torsion spring is fixed on the housing; the spring ring of the second torsion spring is sleeved on the shell, one end of the second torsion spring is fixed on the signal pull rod 12, and the other end of the second torsion spring is fixed on the shell; a coil of the third torsion spring is sleeved on the second rotating shaft 20, one end of the third torsion spring is fixed on the bolt 21, and the other end of the third torsion spring is fixed on the shell; the clockwise returning force of the first torsion spring and the counterclockwise returning force of the third torsion spring urge the pawl 11 and the latch bolt 21 to maintain contact.

In summary, in the novel switch trigger mechanism provided by the present invention, the pawl and the latch are kept in contact through the first reset component and the third reset component, the first protrusion is in contact with the edge between the second toggle block and the first gear on the latch, and is in a fully open state, the first protrusion is engaged with the first gear on the latch, and is in a half-lock state, and the first protrusion is engaged with the second gear on the latch, and is in a fully-lock state; the first surface of the lock tongue is provided with a first lock tongue rib and a second lock tongue rib which are arranged along the edge of the lock tongue and used for triggering the first switch and the second switch, so that different trigger signals are realized in different locking states, the driving safety is improved, the problem that the switch signals are easy to be abnormal is avoided, and the service life of the switch trigger mechanism is prolonged.

The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
