Further, a three-way valve is arranged below the lock catch and connected with the vehicle body, a valve core capable of moving linearly is arranged in the three-way valve, the front end of the valve core faces the vehicle door, the rear end of the valve core is overlapped with the swing rod, and the valve core pushes the swing rod to rotate around the rotating shaft.

Still further, the three-way valve is coupled to the vehicle body by a first fastener.

Further, the door lock switch triggering device further comprises a lock tongue, and the lock tongue is connected to the door.

Further, the lock catch is fixedly connected with the vehicle body through a second fastening piece.

Further, a switch bracket is fixedly arranged on the upper part of the lock catch, and the locking switch is arranged on the upper part of the switch bracket.

Furthermore, the length of the swing rod and the size of the switch bracket are adjusted simultaneously, so that the door lock switch triggering device can adapt to different lock tongue overlap joint lengths under the condition that other factors are unchanged, the triggering stroke of the locking switch is changed, and the locking switch is ensured to be reliably triggered and cannot be over-pressed.

Further, the switch bracket is fixedly connected with the lock catch through a third fastener.

Further, the first, second and third fasteners are all screws.

The beneficial effects are that: compared with the prior art, the utility model has the following advantages:

(1) According to the utility model, the swing rod is arranged on the lock catch, the swing rod is utilized to realize reversing of the movement direction of the lock tongue, and the locking switch and the lock catch can be arranged side by side in this way.

(2) According to the utility model, the length of the swing rod is adjusted, so that the distance that the lock tongue stretches into the lock catch can be more reasonably converted into the stroke for triggering the locking switch, different overlap lengths of the lock tongue can be adapted, and the locking switch is ensured to be reliably triggered and cannot be over-pressed.

(3) The utility model has the advantages of simple structure, high reliability, strong adaptability and the like.

Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-3, the door lock switch triggering device comprises a lock tongue 1, a lock catch 2, a locking switch 3, a switch bracket 4, a vehicle body 5, a fastening piece 6, a fastening piece 7, a rotating shaft 8, a swinging rod 9, a valve core 10, a three-way valve 11 and a fastening piece 12. The lock catch 2 is fixedly connected with a vehicle body through a second fastener 7, a switch bracket 4 is fixed on the upper portion of the lock catch 2 through a third fastener 6, a locking switch 3 is fixed on the upper portion of the switch bracket 4, a swinging rod 9 is arranged between the lock catch 2 and the locking switch 3, the swinging rod 9 is arranged on a rotating shaft 8, the rotating shaft 8 is connected to the lock catch 2, and the swinging rod 9 can rotate around the rotating shaft 8, so that the locking switch 3 is driven to trigger or release. A three-way valve 11 is arranged below the lock catch 2, the three-way valve 11 is connected with a vehicle body through a first fastener 12, a valve core 10 capable of moving linearly is arranged inside the three-way valve 11, the front end of the valve core 10 faces towards a vehicle door, the rear end of the valve core 10 is overlapped with the swing rod 9, and the valve core 10 pushes the swing rod 9 to rotate around the rotating shaft 8. Meanwhile, the length of the swing rod 9 and the size of the switch bracket 4 are adjusted, so that the trigger stroke of the locking switch 3 can be changed under the condition that other factors are unchanged, and the locking switch 3 is ensured to be reliably triggered and cannot be over-pressed.

The working mechanism is as follows: when the vehicle door is closed (as shown in fig. 1-2), the lock tongue 1 is overlapped with the lock catch 2, and pushes the valve core 10 in the three-way valve 11 to move, the valve core 10 pushes the swing rod 9 to rotate around the rotating shaft 8, and the swing rod 9 drives the locking switch 3 to trigger, so that a vehicle door locking signal is provided. When the door is opened (as shown in fig. 3), the lock tongue 1 is disengaged from the lock catch 2, the valve core 10 is retracted to the initial state, the lock switch 3 is released, and the swing rod 9 is pushed to rotate to the initial state.

By adjusting the length of the swing rod 9 and correspondingly adjusting the size of the switch bracket 4, the trigger stroke of the locking switch 3 can be changed under the condition that other factors are unchanged. By means of the scheme, the locking switch 3 can adapt to different installation space requirements and adjustment requirements, and the locking switch 3 is guaranteed to be reliably triggered and cannot be over-pressed.
