Description

Technical Field

[0001] The present disclosure relates to the technical field of door locks or hood locks of motor vehicles, and more particularly to a locking device for a motor vehicle and the motor vehicle. Background Art

[0002] With the development of technologies related to motor vehicles such as automobiles, it is desired to obtain better entry and exit space in the automobile.

[0003] Some car models have begun to adopt a design without body B-pillars. When the front and rear doors of the car are opened at the same time, the front and rear doors are no longer separated by the body B-pillars, which can greatly improve the vehicle's entry and exit space.

[0004] Traditional vehicles have front and rear doors that open forward, with the front door locks latched by catches located on the B-pillars and the rear door locks latched by catches located on the C-pillars. With the removal of the B-pillars, the front door locks must find a suitable location on the vehicle.

[0005] Figure 1 A common solution is shown in Figure 2. Figure 1 The upper front door lock is located on the front door frame, and the corresponding lock catch is located on the roof crossbar. The lower front door lock is located on the lower part of the front door, and the corresponding lock catch is located on the floor crossbar. The front door generally opens by rotating, while the rear door can open by sliding. Since the vehicle body has no B-pillar, in order to improve the vehicle's side impact performance, a connection is required between the front and rear doors to prevent the rear door from sliding and disengaging in the event of a side impact. Therefore, it is necessary to add a front door center lock. When both the front and rear doors are locked, the center lock automatically locks, connecting the front and rear doors and improving the strength of the front and rear door systems.

[0006] Because the central lock must automatically lock after both the front and rear doors are locked, and automatically unlock when either the front or rear door is opened, it must be capable of electric locking and unlocking, as well as mechanical unlocking in the event of a vehicle power outage. Due to these functional requirements, traditional designs require two actuators for electric locking and unlocking, respectively. Furthermore, central locks often have complex structures, posing reliability challenges. Summary of the Invention

[0074] The pawl 103 is rotatably disposed on the base plate 101 via a pawl shaft (not shown in the figure). The pawl 103 cooperates with the lock tongue 102 to lock or unlock the lock device 100;

[0075] The locking rod 104 is coaxially arranged with the lock tongue 102. When the locking rod 104 is driven by a first driving force, the locking rod 104 rotates in a first direction around the axis of the lock tongue shaft and drives the lock tongue 102 to rotate in the first direction, so that the lock tongue 102 rotates from the unlocked position to the locked position;

[0076] The unlocking lever 105 is coaxially arranged with the pawl 103. When the unlocking lever 105 is driven by the second driving force, the unlocking lever 105 rotates in a second direction opposite to the first direction around the axis of the pawl shaft and drives the pawl 103 to rotate in the second direction, so that the pawl 103 can be released from the holding position, thereby releasing the pawl 103 from holding the lock tongue 102 in the locked position;
