[0028] The first reinforcing rib 40 is protruded on the second surface 102 and located between the mounting through hole 12 and the first mounting part 30, and the first reinforcing rib 40 extends along the direction in which the first mounting part 30 points to the mounting through hole 12, so as to enhance the stiffness of the force direction of the first mounting part 30 and reduce the risk of deformation or damage of the first mounting part 30 under the high load of bearing the steering drag link.

[0029] The first groove 11, the second groove 21 and the third groove 13 are arranged on the first surface 101 of the gooseneck knuckle 100, so that the gooseneck knuckle 100 is lightened, and the lightweight effect is achieved, and the material cost of the gooseneck knuckle 100 is reduced. Meanwhile, the first reinforcing rib 40 at the first mounting portion 30 can improve the rigidity of the connection between the main body portion 10 and the first mounting portion 30, so as to improve the structural strength of the gooseneck knuckle 100.

[0030] Please continue to refer to Figure 1 and Figure 2 In an embodiment, the first groove 11 is further provided with a plurality of connecting holes 14, and the plurality of connecting holes 14 are arranged around the mounting through hole 12 at intervals. The hub can be fixed on the gooseneck knuckle 100 by means of bolts passing through the connecting holes 14, so as to improve the stability and reliability of the structure after the hub is mounted on the main body portion 10.

[0031] Please continue to refer to Figure 1 and Figure 2 In an embodiment, the first mounting portion 30 is provided with a first mounting hole 31, and the steering drag rod is movably connected with the first mounting hole 31 on the first mounting portion 30 through a ball joint.

[0032] Please refer to Figure 2 In an embodiment, the first reinforcing rib 40 is in an arc structure, and the arc structure has high bending resistance, so that the gooseneck knuckle 100 can maintain structural stability when bearing a large bending moment.

[0033] Please continue to refer to Figure 2 In an embodiment, the gooseneck portion 20 is provided with a second mounting hole 22, and the upper control arm is movably connected with the second mounting hole 22 on the gooseneck portion 20 through a ball joint.

[0034] Please refer to Figure 1 and Figure 3 In an embodiment, the gooseneck knuckle 100 further comprises a second reinforcing rib 50, which is arranged at the connection between the main body portion 10 and the gooseneck portion 20 and protrudes on the second bottom wall 211 of the second groove 21, and the extension direction of the second reinforcing rib 50 intersects the first direction X. The position between the main body portion 10 and the gooseneck portion 20 is one of the regions that bear the maximum stress in the gooseneck knuckle 100, and since the region needs to simultaneously transmit the loads from the hub, the steering drag rod and the upper control arm, the arrangement of the second reinforcing rib 50 can improve the bending and torsional resistance of the region.

[0035] Please continue to refer to Figure 1 and Figure 3In an embodiment, the second reinforcing rib 50 is provided with a reinforcing surface 51 on the side away from the second bottom wall 211. The distance between the reinforcing surface 51 and the second bottom wall 211 gradually decreases from the direction away from the first mounting portion 30, that is, the thickness of the second reinforcing rib 50 gradually decreases from the end close to the first mounting portion 30 to the direction away from the first mounting portion 30, so that the second reinforcing rib 50 can provide different degrees of support at different positions, and more effectively disperse and guide stress.

The position between the main body portion 10, the second mounting portion 60 and the third mounting portion 70 is one of the regions of the goose neck knuckle 100 that bears the maximum stress, because this region needs to simultaneously transmit the load from the hub, the brake caliper and the lower control arm, and the arrangement of the third reinforcing rib 80 can improve the bending and torsional resistance of this region.

[0042] Please continue to refer to Figure 1 and Figure 4 In an embodiment, the first bottom wall 111 of the first recess 11 is concavely provided with an avoidance groove 113 communicating with the first recess 11, and the avoidance groove 113 is used for avoiding the connecting member (not shown in the figure) connecting the third mounting portion 70 and the lower control arm, so as to provide sufficient space for the connecting member and reduce the interference or collision of the connecting member with other parts of the goose neck knuckle 100.

[0043] In the embodiment, the connecting member connecting the third mounting portion 70 and the lower control arm is a spherical hinge member.

[0044] Please refer to Figure 1 , Figure 2 and Figure 5 The application further provides a vehicle 200 comprising the goose neck knuckle 100 described above. The goose neck knuckle 100 cooperates with the hub, the upper control arm, the lower control arm, the steering tie rod and the brake caliper in the vehicle 200 to ensure that the wheels always maintain the correct positioning angle during driving, thereby improving the handling and comfort of the vehicle 200. Meanwhile, the goose neck knuckle 100 arranges reinforcing ribs in the main load direction to increase the stiffness performance of the corresponding connecting points. In the regions that contribute little to the stiffness performance, the recess feature is increased to reduce the material and the thickness of the material in the region, so as to ensure the stiffness performance while achieving the weight reduction target.
