A door hinge assembly 100 according to an embodiment of the present utility model is described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a door hinge assembly 100 according to an embodiment of the present utility model includes a guide block 10 and a hinge assembly 20.

Specifically, the guide block 10 is provided with a housing chamber 14 therein, the first side 11 of the guide block 10 is provided with a first mounting hole 15, the guide block 10 is provided on the vehicle body through the first mounting hole 15, the second side 12 of the guide block 10 is provided as a guide surface 13 extending obliquely toward the outside of the vehicle body with respect to the longitudinal direction of the vehicle body, and the first side 11 and the second side 12 of the guide block 10 are adjacent two side surfaces of the guide block 10. The hinge assembly 20 is provided in the receiving chamber 14, a portion of the hinge assembly 20 corresponds to the position of the first mounting hole 15 and is connected to the vehicle body through the first mounting hole 15, and another portion of the hinge assembly 20 is connected to the vehicle door, and in the event of a collision of the door hinge assembly 100, the guide block 10 changes the displacement direction of the collider and the moving impact direction of the collider through the guide surface 13 to protect the hinge assembly 20 in the receiving chamber 14.

In other words, referring to fig. 1 and 2, the door hinge assembly 100 according to the embodiment of the present utility model is mainly composed of the guide block 10 and the hinge assembly 20. Wherein, be provided with in the guide block 10 and hold chamber 14, the first side 11 of guide block 10 is provided with first mounting hole 15, and guide block 10 can be installed on the automobile body through first mounting hole 15. For example, the guide block 10 may be mounted on an a-pillar of a vehicle body through the first mounting hole 15. As shown in fig. 2 to 4, the second side 12 of the guide block 10 is provided as a guide surface 13 extending obliquely toward the vehicle body outer side with respect to the vehicle body longitudinal direction. Wherein, as shown in fig. 1 and 3, the first side 11 and the second side 12 of the guide block 10 are adjacent two sides of the guide block 10. By providing the guide block 10 with the guide surface 13 (inclined surface) extending obliquely, the displacement direction of the collided object and the direction of the movement impact of the collided object can be changed, and dispersion of collision energy can be achieved.

As shown in fig. 1, the hinge assembly 20 is installed in the receiving chamber 14 of the guide block 10, wherein a portion of the hinge assembly 20 corresponds to the position of the first mounting hole 15, and the hinge assembly 20 may be connected with the a-pillar of the vehicle body through the first mounting hole 15 of the guide block 10. Another portion of the hinge assembly 20 may be coupled to a vehicle door. In the event of a collision of the door hinge assembly 100, the guide block 10 changes the displacement direction of the collided object and the moving impact direction of the collided object by the guide surface 13 to protect the hinge assembly 20 in the receiving chamber 14.

When the striker 30 (striker) hits in the direction of the hinge assembly 20 in the hitting direction, it is possible to hit the guide block 10 first, and a part of the hitting force is transmitted to the a pillar of the vehicle body through the guide block 10. At this time, the a-pillar gives an outward reaction force to the guide block 10, and the guide block 10 is supported by the a-pillar to reduce displacement after being impacted, thereby protecting the hinge assembly 20 from direct impact. Meanwhile, when the striker 30 continuously impacts into the vehicle (the direction of the impact force is shown in the arrow direction in fig. 7), in the process of continuously increasing the impact force, as the guide block 10 is provided with the guide surface 13 which obliquely extends towards the outer side of the vehicle body, the striker 30 is ensured to move along the extending direction of the guide surface 13 (towards-y direction) and further slide out of the vehicle, so that the displacement direction of the striker and the movement impact direction of the striker are changed, the guide block 10 is ensured not to be continuously impacted by the striker 30, the striker 30 is prevented from continuously impacting the hinge assembly 20 due to overlarge impact force, and the risk that the hinge assembly 20 is broken or fails after failure, thereby causing the vehicle door to fall off and the driver to be injured is avoided.
