In order to meet the performance requirements, preferably, the entire second pawl is designed as a metal piece. For the purpose of reducing weight, a weight-reducing structure (such as hollowing out) can be made in the middle of the second pawl, and the second pawl is only composed of one material, of course, the second pawl can also be coated with a layer of plastic. Since the force of the second pawl is smaller than that of the main pawl, the design strength of the second pawl is preferably weaker than that of the main pawl.

In the lock device of the present disclosure, the two feature 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 provided at the same end of the main pawl arm of the main pawl , and the two faces are two adjacent faces.

In the lock device of the present disclosure, when the tongue portion is subjected to an outward force (the force may be the sealing force of the vehicle door), a pressure will be generated on the main pawl, and this pressure will make the main pawl in the unlocking and locking direction (Fig. 1). clockwise).

In order to keep the main pawl in the locked position, a second pawl is designed. The torque of the primary pawl in the unlocking direction exerts pressure on the second pawl, preferably in the direction of the second pawl's center of rotation.

The advantage of this structure design is to reduce the torque generated by the lock tongue to the main pawl to prevent the main pawl from rotating in the unlocking and locking direction, or even turn it into a reverse torque (that is, the main pawl can be turned in the unlocking and locking direction). turn). This reduces the force required to open the door.

According to yet another embodiment of the present disclosure, a vehicle door includes the lock device 100 of any of the above.

In the description of this specification, reference to the terms "one embodiment/mode", "some embodiments/modes", "example", "specific example" or "some examples", etc. are meant to be combined with the embodiment/mode or A particular feature, structure, material, or characteristic of the example description is included in at least one embodiment/mode or example of the present disclosure. In this specification, schematic representations of the above terms are not necessarily directed to the same embodiment/mode or example. Furthermore, the particular features, structures, materials or characteristics described may be combined in any suitable manner in any one or more embodiments/means or examples. Furthermore, those skilled in the art may combine and combine the different embodiments/modes or examples described in this specification and the features of the different embodiments/modes or examples without conflicting each other.

In addition, the terms "first" and "second" are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, a feature delimited with "first", "second" may expressly or implicitly include at least one of that feature. In the description of the present disclosure, "plurality" means at least two, such as two, three, etc., unless expressly and specifically defined otherwise.

Those skilled in the art should understand that the above-mentioned embodiments are only for clearly illustrating the present disclosure, rather than limiting the scope of the present disclosure. For those skilled in the art, other changes or modifications may also be made on the basis of the above disclosure, and these changes or modifications are still within the scope of the present disclosure.
