Referring to fig. 1 and 2, an embodiment of the present application provides a bending structure, which belongs to the technical field of automobile installation accessories and is mainly applied to an installation support of an on-vehicle domain controller, so as to install the on-vehicle domain controller.

Referring to fig. 1, the bending structure provided in this embodiment includes a first plate-shaped element 10 and a second plate-shaped element 20, the second plate-shaped element 20 is connected to the first plate-shaped element 10, an arc-shaped bending portion 30 is formed at a connection position of the second plate-shaped element 20 and the first plate-shaped element 10, a bending process groove 31 is formed on the arc-shaped bending portion 30, the bending process groove 31 can be formed along a length direction of the second plate-shaped element 20, and a preset distance is formed between two ends of the bending process groove 31 and two opposite edge portions of the second plate-shaped element 20 in the length direction.

It should be noted that the bending structure provided in the embodiment of the present application is a sheet metal structure formed by integrally bending, and for convenience of description, the bending structure is specifically divided into the first plate-like member 10, the second plate-like member 20, and the arc-shaped bending portion 30. Wherein the first plate-like member 10 and the second plate-like member 20 have the same thickness.

In addition, the bending process groove 31 is widely applied in the field of sheet metal manufacturing, is also called as a bending process line, and is an auxiliary positioning groove for pressing and binding a sheet metal before bending in order to position a bending position and ensure bending accuracy.

In this embodiment, a preset distance is formed between each of two ends of the bending process groove 31 and two opposite edge portions of the second plate-like member 20 in the length direction, and it can be understood that: the bending process groove 31 is formed in the middle of the arc-shaped bending portion 30 in the length direction, the bending process groove 31 extends to two opposite edge portions of the second plate-shaped member 20 along the length direction of the second plate-shaped member 20, and two ends of the bending process groove 31 are spaced from two opposite edge portions of the second plate-shaped member 20 in the length direction by the same preset distance.

In the prior art, the bending process line is usually made throughout the entire bending width, i.e. the length of the bending process line runs through the length of the first plate-like element 10. Although the positioning and the precision of the bending process of the bending structure are ensured, the strength of the bending structure is greatly influenced, and when the bending structure is impacted, stress concentration is easily caused, so that the connecting position of the first plate-shaped element 10 and the second plate-shaped element 20 of the bending structure is broken.

In view of the above problems, the present application provides a bending structure in which the bending groove 31 does not extend through the bending width, that is, the bending groove 31 does not extend through the arc-shaped bending portion 30. The design mode of the bending process groove 31 can improve the connection strength of the first plate-shaped member 10 and the second plate-shaped member 20 on the basis of realizing bending positioning and bending precision, thereby reducing the fracture risk of the bending structure.

For example, the ratio X of the preset distance P to the thickness of the first plate-like member 10 may be set to 2, 2.5, 2.9, 3, etc.

With the above example, it is understood that the larger the value of X, the greater the connection strength of the first plate-like member 10 and the second plate-like member 20, but the lower the bending accuracy. The smaller the value of X, the higher the bending accuracy, but the lower the connection strength between the first plate-like member 10 and the second plate-like member 20.
