  • Patent number: 10710530
    Abstract: An adjustable bracket for installation of a vehicle bumper on a body of a vehicle is provided. The bracket is configured to be connected to the body to support the bumper, characterized in that the bracket includes a fixed bracket and an adjusting bracket, wherein the bracket has a movable connection between the fixed bracket and the adjusting bracket, which allows the adjusting bracket to have a translational movement in the vertical direction of the vehicle with respect to the fixed bracket, and wherein the adjusting bracket is provided at its top with position-limiting means which can abut against a light of the vehicle, and wherein the fixed bracket and the adjusting bracket are both provided with a mounting structure fastened to the same body. The adjustable bracket enables the bumper to be vertically positioned by the adjusting bracket, which controls the matching clearance between the bumper and the light, thereby effectively reducing the risks of uneven match between the light and the bumper.

  • Patent number: 10611327
    Abstract: An outer body part assembly for a vehicle, including an outer skin and a support member fixed to the outer skin. The outer skin is attached on a structural module of the vehicle via the support member, the support member includes a main body and a flange edge arranged around the main body and connected with the outer skin, the main body is in the form of mesh structure and includes a contact portion for supporting the outer skin and a reinforcement rib projecting from the contact portion for reinforcing the contact portion. The assembly prevents the outer skin from sinking, benefiting from the lightweight of the main body of the mesh structure, and the main body meets the supporting strength requirements by enhancing the strength of the mesh structure with the reinforcement ribs. In addition, the mesh structure also provides an effective energy absorption in case of a crash.
