Description

Technical Field

[0001] The present invention relates to the technical field of vehicle body cab locks, and in particular to a protective door combat lock and a door lock integrated control system. Background Art

[0002] For protective vehicles, the lightning protection performance of the cab is particularly important. The combat lock is the second protective lock on the door of the protective vehicle in combat status. The role of the combat lock is to add another lock on the basis of the door lock to prevent the door from automatically opening due to mine explosions and violent attacks when the protective vehicle is performing combat missions, thereby protecting the safety of the people in the cab. The traditional combat lock and door lock are independently controlled by two systems, and two handles need to be operated separately when opening the door. The battlefield situation changes rapidly. In an emergency, when the people in the cab need to open the door and get off, the two door opening actions will prolong the door opening time of the occupants and increase the safety threats to the occupants. Therefore, it is necessary to design a protective door combat lock and door lock integrated control system to solve the problems of low efficiency and low safety of the two door opening actions of the existing protective vehicle cab door. Summary of the invention

[0006] The transmission control assembly is connected to the upper transmission rod of the battle lock assembly through the upper telescopic rod, and the transmission control assembly is connected to the lower transmission rod of the battle lock assembly through the lower telescopic rod. The telescopic movement of the upper telescopic rod and the lower telescopic rod respectively controls the rotation of the upper block and the lower block to complete the opening and closing of the battle lock.

[0007] The transmission control assembly is connected to the connecting rod of the door lock assembly through the door lock control block, and the telescopic movement of the door lock control block controls the opening and closing of the door lock.

A cylindrical stopper is provided on each side of the central control block 2-4. The cylindrical stoppers are respectively arranged in the grooves of the upper telescopic rod 2-1 and the lower telescopic rod 2-6. The rotation of the central control block 2-4 can simultaneously control the extension and retraction of the upper telescopic rod 2-1 and the lower telescopic rod 2-6. An upper boss is provided on the upper part of the central control block 2-4. The upper boss blocks the lower part of the door lock control block 2-3.

The lock core 4-1 and the inner lock 4-3 control the telescopic movement of the locking slot 4-2 from the inner and outer sides of the door respectively. The locking core 4-1 or the inner lock 4-3 pulls the locking slot 4-2 to telescope. The locking slot 4-2 of the locking assembly 4 controls the handle connecting rod 3-2 of the handle assembly 3 through telescopic movement. The locking slot 4-2 controls the opening and closing of the entire system.

One lower transmission rod 1-4 is rotatably connected in the pin shaft hole through the pin shaft, and another lower transmission rod 1-4 is slidably connected in the bar hole through the pin shaft. The telescopic movements of the upper telescopic rod 2-1 and the lower telescopic rod 2-6 respectively control the rotation of the upper block 1-2 and the lower block 1-5 to complete the opening and closing of the combat lock.

[0042] The transmission control assembly 2 is connected to the connecting rod 5-2 of the door lock assembly 5 through the door lock control block 2-3. The door lock can adopt different forms (such as tongue spring door lock, hook spring door lock, card plate door lock), and the connection control is performed separately by changing the shape of the connecting rod 5-2. The telescopic movement of the door lock control block 2-3 controls the opening and closing of the door lock.

[0043] In this embodiment, when the vehicle door is closed, the handle assembly is rotated 390° counterclockwise, and the handle assembly 3 drives the central control block 2-4 in the transmission control assembly 2.

At this time, the combat lock is in a closed state, and then the inner lock 4-3 in the locking assembly 4 is rotated to extend the locking slot 4-2. The locking slot 4-2 completely blocks the handle connecting rod 3-2 in the handle assembly 3, and the entire system is in a locked state.

[0044] In this embodiment, when the door is to be opened, the inner lock 4-3 in the lock assembly 4 is first rotated to shrink the lock slot 4-2, and then the handle assembly is rotated 390° clockwise, the handle assembly 3 drives the central control block 2-4 in the transmission control assembly 2, and the central control block 2-4 controls the upper telescopic rod 2-1 and the lower telescopic rod 2-6 to shrink at the same time, and the upper telescopic rod 2-1 and the lower telescopic rod 2-6 respectively drive the upper transmission rod 1-3 and the lower transmission rod 1-4 in the combat lock assembly 1 to move in the same direction, thereby This causes the upper block 1-2 and the lower block 1-5 to rotate a certain angle, the upper block 1-2 is disengaged from the upper block lock bolt 1-1, and the lower block 1-5 is disengaged from the lower block lock bolt 1-6. At this time, the combat lock is in the open state, and then the handle assembly 3 continues to be rotated clockwise. The handle assembly 3 drives the central control block 2-4 in the transmission control assembly 2. The central control block 2-4 controls the door lock control block 2-3 to move to the right, causing the connecting rod 5-2 in the door lock assembly 5 to move, so that the lock body 5-1 is opened.
