In the following detailed description, directional terms, such as "left", "right", "upper", "lower", "front", "rear", and the like, are used with reference to the orientation as illustrated in the drawings. The components of the various embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.
Referring to fig. 2 to 3, there is shown a mounting bracket 100 for a wiper blade of an automobile according to a preferred embodiment of the present invention, the mounting bracket 100 having a bracket body 4, an upper support leg 2 provided at an upper portion of the bracket body 4, a front support leg 3 provided at a lower portion of the bracket body 4, and a middle support leg 1 extending outward from a middle portion of one side of the bracket body 4. The far end of the upper supporting leg 2 is fixedly lapped on a beam upper plate 5 of the automobile windshield, and the far end of the front supporting leg 3 is fixedly lapped on a firewall outer plate 6 of the automobile windshield. The middle support foot 1 extends obliquely downward from the middle of the bracket main body 4, and the middle support foot 1 is arranged as a sprag bracket main body 4, the distal end of which is used for fixedly lapping on an outer plate 6 on a firewall.
Herein, the proximal side of the support foot is defined as the side toward the holder main body 4, and the distal side of the support foot is defined as the side away from the holder main body 4.
Referring to fig. 2-3, the middle supporting leg 1 of the main body 4 of the sprag bracket can provide an auxiliary support in the axial direction (i.e., in the N direction in fig. 3) at the mounting point of the wiper blade, so as to effectively increase the axial rigidity of the mounting bracket 100, thereby improving NVH performance. The term "axial" as used herein is understood to mean normal to the surface on which the stent body 4 is placed. Meanwhile, the middle supporting leg 1 can also provide auxiliary support for the bracket main body 4 in the transverse direction (Y direction in fig. 3), so that the width of the overlapping part of the upper supporting leg 2 and the front supporting leg 3 with the external structure can be significantly reduced without affecting the stable installation of the whole mounting bracket 100, thereby reducing the overall weight of the mounting bracket 100. According to some embodiments, the widths of the upper support foot 2, the front support foot 3 and the bracket body 4 may be reduced by as much as 50%, thereby significantly reducing the overall weight of the mounting bracket 100.
According to some preferred embodiments of the present invention, the bracket body 4 is formed with a positioning hole 42 for positioning the mounting bracket 100 of the wiper blade of the automobile with respect to the windshield of the automobile and a mounting hole 43 for mounting the wiper blade.

According to some preferred embodiments of the present invention, the middle part of the middle supporting foot 1 may be formed with a collapsing structure, such as the collapsing structure shown in fig. 2-3, which includes a lightening hole 13 formed in the middle part of the middle supporting foot 1 and a collapsing rib 14 formed to extend across two long sides of the lightening hole 13. The shape of the lightening hole 13 can be an oblong or an ellipse, and the collapsing ribs 14 respectively extend from two side edges of the lightening hole 13 to two side edges of the middle part of the middle supporting leg 1. The collapsing ribs 14 may be arranged in a reciprocating folding structure, so that when the middle supporting leg 1 is subjected to a large external force, the collapsing ribs can collapse to absorb kinetic energy, thereby protecting pedestrians and reducing injury. It should be understood that the collapsing structure can be designed in other types of structures as long as the kinetic energy generated by the external force can be absorbed by the self-deformation.
According to some preferred embodiments of the present invention, a first reinforcing rib 12 is provided at an included angle between the proximal end portion of the middle supporting leg 1 and the bracket main body 4, for reinforcing the strength of the bending portion. Optionally, a second reinforcing rib 22 and a third reinforcing rib 32 extend from intermediate positions of the upper support foot 2 and the front support foot 3, respectively, and in the embodiment shown in fig. 2-3, the second reinforcing rib 22 and the third reinforcing rib 32 are respectively concave or convex relative to the main body surface of the support foot.
According to some preferred embodiments of the present invention, as shown with reference to fig. 2-3, the distal end of the upper supporting leg 2 forms a first flange 21, the first flange 21 is fixedly overlapped on the beam upper plate 5 of the automobile air window, the distal end of the front supporting leg 3 forms a second flange 31, the second flange 31 is fixedly overlapped on the outer plate 6 of the fireproof wall of the automobile air window, the distal end of the middle supporting leg 1 forms a third flange 11, and the third flange 11 is fixedly overlapped on the outer plate 6 of the fireproof wall. The flanging process of the supporting legs is beneficial to the firm lap joint of the supporting legs and the external structure.
Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims.
