The lock seat 10 is connected to the vehicle body, and the lock ring 20 engages with the latch. As shown, the lock seat and the lock ring are integrally formed. Specifically, the lock seat 10 and the lock ring 20 are constructed as a multi-layer structure, which is formed by 3D printing technology, layer by layer, with each layer bonded to the others.

[0026] To facilitate production, the door latch 1 also includes a transition portion 30 of a certain thickness formed between the lock seat 10 and the lock ring 20, which is also formed by 3D printing technology.

[0027] The lock housing 10 is also shown to have an upper side 11 provided with two through holes 11A arranged symmetrically about the lock ring 20 in the length direction (X direction) for the screws to pass through for connection to the vehicle body, and a lower side 12 having a hollowed-out portion 12A centrally located in the X direction and a flat mounting surface 12B. The hollowed-out portion 12A is of elongated configuration extending in the width direction (Y direction) and recessed with respect to the mounting surface 12B. The mounting surface 12B is to be connected to the vehicle body. The through holes 11A are configured to be frustoconical for ease of insertion of the screws.

[0028] In addition, a reinforcing rib 40 of cuboid configuration is formed between the lock housing 10 and the lock ring 20, extending in the height direction (Z direction) from the transition portion 30 to the lock ring 20. The door lock catch 1 is also provided with a reinforcing rib 50 which is contiguous with the right-hand lock post 22. The reinforcing rib 50 is of triangular configuration with its base adjacent to the lock housing 10. Also, a reinforcing rib 60 is provided on the lower side 12 centrally located in the X direction and spanning the lock ring 20 and the hollowed-out portion 12A such that the hollowed-out portion 12A surrounds the reinforcing rib 60. The reinforcing rib 60 is of trapezoidal configuration extending in the Z direction from the mounting surface 12B to the hollowed-out portion 12A with its upper base contiguous with the hollowed-out portion 12B and its lower base flush with the mounting surface 12B.

[0029] By providing the reinforcing ribs 40, 50 and 60, the mounting surface 12B, the height direction Z and the width direction Y of the door lock catch 10 are respectively reinforced, thereby improving the strength of the door lock catch 10.

[0030] The lock ring 20 comprises a lock hole 21 and two cylindrical lock posts 22 formed around the lock hole 21. The lock posts 22 are connected at their upper ends via a crossbar 23 and at their lower ends via the reinforcing rib 40. The lock hole 21 is for the passage of the locking tongue, and the left-hand lock post 22 is to engage with the locking tongue.

[0031] In this example, an additional coating 22A is also applied on the surface of the right-hand lock post 22 of the lock ring 20.
