The trigger portion 118 is connected to the main pawl 102 and rotates with the rotation of the main pawl 102. When the main pawl 102 rotates to a predetermined position, the trigger portion 118 triggers the switch portion 119, and the switch portion 119 obtains the current position information of the main pawl 102.

[0142] Preferably, the main pawl 102 has a connecting rod 121 , and the main pawl 102 is connected to the triggering portion 118 via the connecting rod 121 .

[0143] The triggering portion 118 has a mounting hole 122 , and the connecting rod 121 of the main pawl 102 is connected to the triggering portion 118 through the mounting hole 122 of the triggering portion 118 .

[0144] The trigger portion 118 is further provided with a rotation hole 120 , and the rotation hole 120 can cooperate with other rotation shafts, so that the trigger portion 118 can rotate along with the rotation of the main pawl 102 .

[0145] The lock device of the present disclosure can hold a door or a cover by rotating the lock tongue portion 101 (counterclockwise), so that the door or the cover cannot be opened.

[0146] If the locking bolt portion 101 is rotated to be located in the open position, the locking bolt portion 101 can leave the locking device, and the door or lid can be opened.

[0147] When the lock device 100 is open, the bolt portion 101 is in the open position. When the door or cover is closed, the bolt portion 101 is pushed to rotate in the locking direction, thereby achieving a half-lock (the secondary pawl 107 is engaged with the locking surface 109 of the bolt portion 101, Figure 2The state shown in the figure) is then reached to be fully locked (the locking surfaces of the main pawl 102 and the bolt portion 101 are engaged).

[0148] The lock device 100 in both the half-locked position and the fully-locked position can keep the vehicle door or the hood from being opened.

[0149] The lock device disclosed in the present invention can realize opening the door or cover with a small operating force under the condition of a large door sealing reaction force, and has a reliable structure and low cost.

[0150] In order to ensure the safety of the locking device, the present invention is also specially designed that when the spring of the main pawl and / or the second pawl breaks, the main pawl and the second pawl will move in the direction of locking the door under the action of their own gravity ( Figure 1 The door can still be locked well (counterclockwise) to ensure the safety of the vehicle.

[0151] In order to meet the performance requirements, preferably, the entire second pawl is designed as a metal part. For the purpose of weight reduction, a weight reduction structure (such as hollowing) can be made in the middle of the second pawl, and the second pawl is made of only one material. Of course, a layer of plastic can also be wrapped outside the second pawl. Since the force on the second pawl is smaller than that on the main pawl, the design strength of the second pawl is preferably weaker than that on the main pawl.

[0152] In the lock device disclosed in the present invention, the two characteristic structures of the locking surface designed for the main pawl to be locked in the main locking position and the locking surface of the main pawl are arranged at the same end of the main pawl arm of the main pawl, and the two surfaces are two adjacent surfaces.

[0153] In the lock device disclosed in the present invention, when the lock tongue is subjected to an outward force (this force may be the sealing force of the vehicle door), a pressure is generated on the main pawl, and this pressure causes the main pawl to move in the unlocking direction ( Figure 1 clockwise in the direction of rotation).

[0154] In order to keep the main pawl in the locked position, a second pawl is designed. The torque of the main pawl in the unlocking direction will produce pressure on the second pawl, and the direction of the pressure preferably passes through the rotation center of the second pawl.

[0155] The advantage of this structural design is that the torque generated by the lock tongue on the main pawl to prevent the main pawl from rotating in the unlocking direction is reduced, and even turned into a reverse torque (that is, it can make the main pawl rotate in the unlocking direction). In this way, the force required to open the door is reduced.

[0156] According to yet another embodiment of the present disclosure, a vehicle door includes any one of the lock devices 100 described above.
