Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

FIG. 1 is a schematic structural diagram of a bracket connected to a subframe and a toe-in arm according to an embodiment of the present invention. In this embodiment, there are two brackets 100 , and both brackets 100 are connected to the subframe 200 . The two brackets 100 are axially symmetrically arranged opposite each other, and each bracket 100 is connected to one of the toe-in arms 300 at the outer side (the left side of the left bracket 100 belongs to the outer side, and the right side of the right bracket 100 belongs to the outer side). And the toe-in arm 300 can rotate and translate when connected to the corresponding bracket 100.

Specifically, FIG. 2 is a schematic structural diagram of a stent according to an embodiment of the present invention; FIG. 3 is a schematic structural diagram of another angle of the stent according to an embodiment of the present invention. This embodiment provides a bracket 100 for connecting a subframe 200 and a toe arm 300 of a vehicle, and the bracket 100 may include a connecting part 10 and a mounting part 20 . Wherein, the connecting portion 10 is connected to the sub-frame 200 by a first fastener (not shown in the figure, specifically, the first fastener may be a bolt, a screw, etc.). One end of the mounting portion 20 is connected with the connecting portion 10 and the other end is connected with the toe-in arm 300 , and the mounting portion 20 is configured to be able to rotate and translate when the toe-in arm 300 and the mounting portion 20 are connected together.

The bracket 100 in this embodiment only includes the connecting portion 10 and the mounting portion 20 , and has a compact structure, small volume and light weight, and can realize configuration switching under the condition of limited space structure.

In fact, since the bracket 100 in the prior art is fixed when it is connected with the toe-in arm 300, the toe-in arm 300 cannot be adjusted, resulting in the restriction of the toe-in arm 300 in actual use, which makes the four-wheel alignment parameters It can only be guaranteed by the accuracy, which increases the cost. When the bracket 100 in this embodiment is connected to the toe-in arm 300, the toe-in arm 300 can rotate and move, which solves the problem that the four-wheel alignment parameters can only be guaranteed by the accuracy, so that the machining accuracy of the relevant parts of the entire vehicle can be reduced , thereby reducing processing and manufacturing costs.

As an embodiment of the present invention, the mounting portion 20 is configured to have a “U” shape in cross section, and includes a support portion 21 that is opposite to each other and is spaced apart and a bridge portion 22 that connects the two support portions 21. The toe-in arm 300 passes through the second support portion 21. Fasteners 30 are provided between the two supports 21 . The bridge portion 22 is connected to the connection portion 10 , and each support portion 21 extends from the bridge portion 22 to the opposite direction to the connection portion 10 . For example, in FIG. 2 , the support portion 21 extends to the left, and the connection portion 22 is at the right side.

In addition, as an embodiment, each support portion 21 is plate-shaped and is provided with a waist-shaped hole 23, the plate surfaces of the two support portions 21 are parallel to each other, and the two waist-shaped holes 23 are arranged corresponding to each other to allow the same second The fasteners 30 are passed through to set the toe-in arm 300 at the support portion 21, so that the toe-in arm 300 can be rotated about the second fastener 30 as an axis, and the toe-in arm 300 can be rotated with the second fastener The piece 30 translates along the waist hole 23 . In this embodiment, the center-to-center distance of each waist-shaped hole 23 is 10-15 mm. For example, it can be 10mm, 12mm or 15mm. Then, the travel of the toe-in arm 300 with the translation of the second fastener 30 may be 10-15 mm.

The cross-section of the mounting portion 20 in this embodiment is a "U" shape, and may include a support portion 21 and a bridge portion 22. The support portion 21 extends to the left, so that the opening of the mounting portion 20 faces the left side in the figure. At the same time, the two The plane where the support portion 21 is located is substantially parallel to the surface of the subframe 200 adjacent to the support portion 21 . There is a space between the two support parts 21 to accommodate the toe-in arm 300, and the toe-in arm 300 can rotate along a plane parallel to the plane of the support part 21. The angle at which the toe-in arm 300 is rotated is related to the positions of the bracket 100 and the toe-in arm 300 and the installation positions of other surrounding components. However, when the toe-in arm 300 is rotated, due to the limitation of space, the rotation and translation of the toe-in arm 300 will be performed at the same time, so as to ensure the normal movement of the toe-in arm 300 .

In addition, the support portion 21 has waist-shaped holes 23 , and the second fastener 30 passes through the waist-shaped holes 23 of the two support portions 21 and the toe-in arms 300 to connect the mounting portion 20 and the toe-in arms 300 together. In this embodiment, the second fastener 30 may be a bolt, and since the bolt is circular, the toe-in arm 300 can rotate around the bolt. Since the bolts are arranged in the waist-shaped holes 23 , the bolts can also translate along the waist-shaped holes 23 . Therefore, the toe-in arm 300 also translates along the direction of the waist hole 23 together with the bolt. In fact, during the actual use of the toe-in arm 300 in the prior art, since the toe-in arm 300 cannot be adjusted, the four-wheel alignment parameters cannot be adjusted, or can only be adjusted through the adjustment precision, which increases the cost. In this embodiment, the toe-in arm 300 can be rotated and moved directly through the bracket 100 , so that the four-wheel alignment parameters can be adjusted, and the cost can be reduced while satisfying the performance of the vehicle.

When the central axes between the through holes 11 are not parallel, it indicates that the connecting portion 10 may not be arranged on a plane, so the plurality of through holes 11 and the plurality of first fasteners are not arranged in parallel and side by side, but may have different kind of angle. It should be noted that the case where the central axes of the plurality of through holes 11 are not parallel may include that the central axes of some of the through holes 11 are parallel, while the central axis of another part of the through holes 11 is the same as the central axis of this part of the through holes 11 The case of non-parallel may also include the case that the central axes of all the through holes 11 are not parallel to each other. The angle between the central axes of the non-parallel through holes may be in the range of 0-10 degrees (excluding 0 degrees). The specific angle of the through hole is related to its suitable mounting surface. This design can adapt to more mounting surfaces, and the adapted mounting surface can be freely designed according to the space and stress requirements, so that the entire structure can not only meet the performance, but also meet assembly requirements.
