[0025] Please refer to Figure 1 and 2 The embodiment of the utility model provides a construction machinery cab door lock system, which mainly includes a lock body assembly, an outer opening component, an inner opening component 7 and a keyless opening component.
[0026] The lock assembly generally consists of a lock body 4 and a lock catch 8, and the door can be locked and opened by the lock body 4 and the lock catch 8. The lock body 4 is installed at the rear of the door, and the lock catch 8 is installed at the B-pillar of the vehicle body. Here, the lock catch 8 is fixedly installed on the B-pillar of the vehicle body by bolts, and the lock body 4 is embedded in the rear side of the door and fixed by bolts. The position of the lock body 4 corresponds to the position of the lock catch 8. When the door is closed, the lock catch 8 is inserted into the lock body 4, and the lock body 4 automatically locks the lock catch 8.
[0027] An actuator is disposed in the lock body 4 , and the actuator is generally an electric actuator. The actuator can drive the lock body 4 to work so that the lock body 4 is unlocked, that is, the lock body 4 enters a locked state or an unlocked state.
[0028] The lock assembly can be flexibly selected from various existing central locks according to actual application needs. As described in this embodiment, the lock assembly selects the DM02 central lock produced by Jiangsu Xushun Dongmingyun Intelligent Technology Co., Ltd.
[0029] The outer opening assembly is arranged on the outer side of the vehicle door, and includes a lock core 12 and an outer opening button 11. Generally, an outer opening handle 1 is arranged on the outer side of the vehicle door, and the outer opening handle 1 is directly mounted on the vehicle door, and the lock core 12 and the outer opening button 11 are both arranged on the outer opening handle 1. Here, in order to facilitate the connection between the lock core 12 and the outer opening button 11 and the lock body 4, the lock core 12 and the outer opening button 11 are both arranged on the rear edge of the vehicle door, and the lock core 12 is located above the outer opening button 11.
[0030] The lock core 12 is connected to the lock body 4 through the lock core connecting rod 2, so that the lock body 4 is unlocked by the lock core connecting rod 2. Here, the lower end of the lock core connecting rod 2 is connected to the lock core 12, and the upper end is connected to the outer locking rocker arm of the lock body 4. The lock core connecting rod 2 drives the outer locking rocker arm to move, thereby driving the lock body 4 to enter a locked state or an unlocked state.
[0031] The outer opening button 11 is connected to the lock body 4 through the outer opening cable 3, so that the lock body 4 is driven by the outer opening cable 3 to unlock the lock buckle 8. Here, the lower end of the outer opening cable 3 is connected to the outer opening button 11, and the upper end is connected to the outer opening rocker arm of the lock body 4. The outer opening cable 3 drives the outer opening rocker arm to move, thereby driving the lock body 4 to release the lock buckle 8 and unlock the lock buckle 8.
[0032] The inner opening assembly 7 is arranged on the inner side of the vehicle door. Generally, in order to facilitate the operation in the cab, the inner opening assembly 7 is arranged on the outer side of the cab seat. The inner opening assembly 7 includes an inner locking button 14 and an inner opening handle 15.
[0033] The inner locking button 14 is connected to the lock body 4 through the inner locking cable 5, so as to drive the lock body 4 to unlock through the lock core connecting rod 2. Here, one end of the inner locking cable 5 is connected to the inner locking button 14, and the other end is connected to the locking dial plate of the lock body 4. The inner locking cable 5 drives the locking dial plate to move, thereby driving the lock body 4 to enter a locked state or unlocked state.
[0034] The inner opening handle 15 is connected to the lock body 4 through the inner opening pull wire 6, so that the lock body 4 is driven by the inner opening pull wire 6 to unlock the lock buckle 8. Here, one end of the inner opening pull wire 6 is connected to the inner opening handle 15, and the other end is connected to the inner opening toggle plate. The inner opening pull wire 6 drives the inner opening toggle plate to move, thereby driving the lock body 4 to release the lock buckle 8 and unlock the lock buckle 8.
[0035] The keyless opening component includes a keyless entry switch 13, a door lock controller 9 and a remote control key 10. The keyless entry switch 13 is arranged on the outside of the vehicle door. The keyless entry switch 13 is connected to the door lock controller 9. The keyless entry switch 13 can sense the remote control key 10 within a predetermined distance, so that the remote control key 10 can be wirelessly connected to the keyless entry switch 13 and send a control signal to the keyless entry switch 13.
[0036] The door lock controller 9 is disposed in the vehicle door and connected to the lock body assembly. Here, the door lock controller 9 is specifically connected to the actuator, and the actuator is controlled by the door lock controller 9 to move, thereby driving the lock body 4 to move, so that the lock body 4 enters a locked state or an unlocked state. Here, the actuator, the door lock controller 9 and the keyless entry switch 13 are electrically connected through a wiring harness.
[0037] The construction machinery cab door lock system can work in a variety of ways:
[0038] When the vehicle door outside the cab is closed and needs to be opened, the lock core 12 is rotated by holding the mechanical key to drive the lock core connecting rod 2 to unlock the lock body 4, and then the outer opening button 11 is pressed to drive the outer opening pull wire 3, so that the lock body 4 unlocks the lock buckle 8, and then the outer opening handle 1 is pulled to open the vehicle door.
[0039] When the remote control key 10 is held and the remote control key 10 is close to the vehicle door, the keyless entry switch 13 is touched. At this time, the door lock controller 9 receives the unlocking signal sent by the keyless entry switch 13, and the door lock controller 9 controls the actuator to unlock the lock body 4, and then presses the outer opening button 11 to drive the outer opening pull wire 3, so that the lock body 4 unlocks the lock buckle 8, and then pulls the outer opening handle 1 to open the vehicle door.
[0040] When the door in the cab is closed and needs to be opened, the inner locking button 14 is pressed to drive the inner locking wire 5 to unlock the lock body 4, and then the inner opening handle 15 is pulled to drive the inner opening wire 6, so that the lock body 4 unlocks the lock buckle 8, and the door is pushed outward to open.
[0041] When the door needs to be locked while holding the remote control key 10, when the remote control key 10 is away from the vehicle door by a predetermined distance, the keyless entry switch 13 will send a lock signal to the door lock controller 9. At this time, the door lock controller 9 controls the actuator to lock the lock body 4 to achieve the locked state of the vehicle door.
