Description

Technical Field

[0001] This application belongs to the technical field of connectors, and particularly relates to a connection mechanism and connector for realizing a connection between two layers of parallel or non-parallel planes and curved surfaces. Background Technology

[0002] In existing industrial production equipment, it is common for certain parts of products to be designed with double-layered structures due to functional requirements. For example, many parts of automotive structures require local double-layered structures. Sometimes, these double-layered structures do not have very stringent requirements for connection strength, while others require ease of installation. Currently, the common connection method in mechanical structures is to connect two components using screws, bolts, or other threaded connections. This connection method is cumbersome in terms of threaded locking and operation. Furthermore, it requires through-holes or threaded holes in the components, especially larger ones, for the screws, bolts, and other connecting parts to pass through. In cases where high sealing requirements are needed, the presence of through-holes or threaded holes can compromise the integrity of the seal, causing instability in the overall operation of the component.

[0003] There is currently no effective solution to the above problems.

[0040] Reference Figure 1 As shown, this application embodiment provides a connection mechanism for realizing two layers of parallel or non-parallel planes and curved surfaces, including:

[0041] The connector 1 has a main body 11 and a first end 12 and a second end 13 that are far apart from each other;

[0042] The first plate 2 is connected to the first end 12;

[0043] The second plate 3 is connected to the second end 13;

[0044] Wherein, the outer diameter of the first end 12 and the second end 13 is smaller than the outer diameter of the main body 11, the first end 12 extends toward the direction of the first plate 2 to contact the inner wall material of the first plate 2, and the second end 12 extends toward the direction of the second plate 3 to contact the inner wall material of the second plate 3.

[0045] The plane containing the first plate 2 is separated from the plane containing the second plate 3, or the first plate 2 and the second plate 3 are in a curved surface.

[0046] according to Figure 1 Those skilled in the art can configure the connector 1 to have a main body 11, the main body 11 having a first end 12 and a second end 13, wherein the first end 12 and the second end 13 are disposed at opposite ends on the main body 11.

[0047] In this plate connection structure, those skilled in the art can install the first plate 2 and the second plate 3 on the first end 12 and the second end 13, respectively. Specifically, the first end 12 extends toward the direction of the first plate 2 to contact the inner wall material of the first plate 2, and the second end 13 extends toward the direction of the second plate 3 to contact the inner wall material of the second plate 3.

[0048] With the above structure, the first plate 2 and the second plate 3 can be connected by the first end 12 and the second end 13 of the connector 1, so that the first plate 2 and the second plate 3 can be fixedly connected.

[0049] In the above configuration, those skilled in the art would set the plane containing the first plate 2 to be separate from the plane containing the second plate 3. That is, the plane containing the first plate 2 and the plane containing the second plate 3 can be connected through the first end 12 and the second end 13, whether they are parallel or not. Furthermore, those skilled in the art would further set the planes containing the first plate 2 and the second plate 3 to be curved surfaces.

[0050] In summary, those skilled in the art can connect the first plate 2 and the second plate 3, which may be parallel or non-parallel or curved, through the first end 12 and the second end 13 of the main body 11.

If the first end 12 or the second end 13 is provided with a toothed portion 14, then the first end 12 is interference-fitted to the first plate 2, or the second end 13 is interference-fitted to the second plate 3.

[0055] In summary, in this embodiment, those skilled in the art will set both the first end 12 and the second end 13 to have a toothed portion 14, or one of the first end 12 and the second end 13 to have a toothed portion 14, so that the first plate 2 and / or the second plate 3 can be interference-fitted.

[0060] Specifically, during the above-mentioned riveting process, the riveting part 15 on the first end 12 squeezes and deforms the material on the first plate 2, and the squeezed and deformed material on the first plate 2 flows into the receiving groove 16, thereby forming a mutually abutting riveting structure, and thus realizing the riveting connection between the first end 12 and the first plate 2.

[0061] Furthermore, in this embodiment, those skilled in the art can provide a riveting portion 15 and a receiving groove 16 on the second end 13, and the riveting portion 15 and the receiving groove 16 are disposed close to each other.

[0065] In another embodiment, preferably, the first end 12 extends through the first plate 2 and is riveted to the first plate; or / and the second end 13 extends through the second plate 3 and is riveted to the second plate 3.

[0066] With the above structure, those skilled in the art can set up a riveting connection between the first end 12 and the first plate 2 or / and between the second end 13 and the second plate 3.

[0067] Specifically, the first end 12 and / or the second end 13 are provided with a beveled portion 17. The beveled portion 17 can be used to rivet the first plate 2 or the second plate 3.

[0068] In the above configuration, those skilled in the art can configure both the first end 12 and the second end 13 to have a beveled portion 17. The beveled portion 17 on the first end 12 extends through the first plate 2 and abuts against the side wall of the first plate 2 away from the second plate 3; the beveled portion 17 on the second end 13 extends through the second plate 3 and abuts against the side wall of the second plate 3 away from the first plate 2.

[0069] In another configuration, those skilled in the art may provide a beveled portion 17 on the first end 12 or the second end 13, thereby enabling a riveting connection between the first end 12 and the first plate 2 or a riveting connection between the second end 13 and the second plate 3.

[0071] In the above embodiments, those skilled in the art can further configure the first plate 2 and the second plate 3. Preferably, the first plate 2 and the second plate 3 are parallel. That is, in the above embodiments, those skilled in the art can connect the parallel first plate 2 and the second plate 3 through the first end 12 and the second end 13 of the main body 11.

[0072] In another embodiment, both the first board 2 and the second board 3 are curved boards. In this embodiment, both the first board 2 and the second board 3 can be set to be curved boards, that is, the plane on which the first board 2 is located and the plane on which the second board 3 is located do not need to be parallel.

[0073] When those skilled in the art set the structure of the first plate 2 and the second plate 3, they can set blind holes on the first plate 2 and the second plate 3, so as to complete the interference connection and riveting connection between the first plate 2 and the first end 12, and the interference connection and riveting connection between the second plate 3 and the second end 13.

[0076] Furthermore, the stepped portions provided on the first end 12 and the second end 13 can increase the contact area between the first plate 2, the second plate 3 and the connector 1. When the first plate 2 and the second plate 3 are subjected to external force, the stepped portions provided on the first end 12 and the second end 13 can bear part of the external force, thereby effectively reducing the degree of deformation of the first plate 2 and the second plate 3.

A second protrusion 19 protruding towards the second plate 3 is provided on the end face of the second end portion 13 of the main body 11. The hardness of the second protrusion 19 is greater than that of the second plate 3, so that the second protrusion 19 can be embedded in the second plate 3. The above embodiment can further ensure the firmness of the connection between the first plate 2 and the second plate 3 and the connector 1, thereby ensuring the stability and safety of the connection mechanism that realizes the connection of double-layer parallel or non-parallel planes and curved surfaces during operation.
