The following describes the implementation of the present invention based on its overall structure.

[0045] Reference Figure 1 As shown, an embodiment of the present application provides a riveted component, comprising:

[0046] A main body 11 having a central axis, the main body 11 having a first end 111 and a second end 112;

[0047] The first end portion 111 extends in a direction away from the middle axis to form a flange portion 12. A connecting portion 121 is provided at an edge of the flange portion 12 away from the middle axis.

[0048] A contact portion 13 is provided between the first end portion 111 and the second end portion 112 , and the outer diameter of the contact portion 13 is smaller than the outer diameter of the flange portion 12 ;

[0049] A groove 14 is formed between the second end portion 112 and the abutting portion 13 in the direction of the middle axis. The outer diameter of the groove 14 decreases linearly from a side close to the second end portion 112 to a side away from the second end portion 112.

[0050] The side wall where the second end portion 112 is located is recessed toward the first end portion 111 to form a groove 15 for accommodating a plate material.

[0051] according to Figure 1 Those skilled in the art can configure the rivet 1 to have a main body 11. The main body 11 has a first end 111 and a second end 112 at either end. A flange 12, a contact portion 13, and a receiving groove 14 are provided between the first end 111 and the second end 112 of the main body 11, respectively, so that the rivet 1 can be used for riveting a plate.

[0052] Specifically, those skilled in the art may provide a flange portion 12 on the first end portion 111. That is, the first end portion 111 of the main body 1 extends in a direction away from the middle axis, thereby forming the flange portion 12.

[0053] With the above structure, the flange 12 can be connected to the plate by interfering with or embedding in the plate. A connecting portion 121 can be further provided on the flange 12. By providing the connecting portion 121 and the flange 13 to securely connect the plate, the rivet 1 can effectively connect the plates.

[0054] Furthermore, those skilled in the art may provide a contact portion 13 between the first end 111 and the second end 112. That is, during the process of connecting the rivet 1 to the plate, the contact portion 13 may penetrate into the plate. After the contact portion 13 penetrates the plate, it contacts or directly abuts against the material within the plate.

[0055] A receiving groove 14 is provided on the second end 112 of the rivet 1 to accommodate the material of the plate. Specifically, near the second end 112 of the main body 11 of the rivet 1, the material on the main body 11 is recessed toward the center axis to form the receiving groove 14.

[0056] More preferably, the outer diameter of the groove 14 decreases linearly from the side closest to the second end 112 to the side farther from the second end 112. That is, the inner wall of the groove 14 is curved. This further stabilizes the process of the sheet material entering the groove 14 and also makes the structure of the main body 1 more stable.

[0057] With the above structure, the wall surface inside the receiving groove 14 is arc-shaped, thereby preventing the presence of a corner structure inside the receiving groove 14 and effectively preventing stress concentration inside the receiving groove 14 .

[0058] In the above embodiment, those skilled in the art can set a connecting portion 121 on the flange portion 12. The connecting portion 121 can be embedded in the material of the plate along with the flange portion 12. Preferably, the connecting portion 121 is configured as a structure with multiple arc surfaces connected.

[0059] Specifically, in this embodiment, the connecting portion 121 is configured to connect arc surfaces. Figure 4 The two adjacent arc surfaces can be curved toward the direction close to the middle axis and toward the direction away from the middle axis respectively. That is, the concave arc surface and the convex arc surface can be connected.

[0060] In the above arrangement, the connection portion 121 is formed by a concave arc surface and a convex arc surface connected to each other and connected end to end, so that the material embedded in the plate in the connection portion 121 can cooperate with the plate material, thereby improving the connection strength of the riveted part 1.

[0061] In one embodiment, those skilled in the art further configure the flange portion 12. Preferably, the flange portion 12 has a first side facing the interference portion 13 and a second side away from the interference portion, the connecting portion 121 is disposed on the first side, and the outer diameter of the connecting portion 121 is less than or equal to the outer diameter of the second side.

[0062] According to the above arrangement, the connecting portion 121 is squeezed before the plate during riveting. In the above arrangement, the outer diameter of the connecting portion 121 is less than or equal to the outer diameter of the second side, so that the connecting portion 121 does not damage the structure of the plate during riveting.

[0063] In another embodiment, preferably, the connecting portion 121 is configured as a plurality of spaced connecting teeth, which can make the connection between the flange portion 12 and the plate more stable.

[0064] Specifically, the tooth-shaped connecting portion 121 can form a tighter engagement structure with the material of the plate. The material of the plate and the side walls of the connecting teeth are squeezed and rubbed against each other, thereby generating greater resistance, thereby preventing the rivet 1 from rotating and failing.

[0065] In an optional embodiment, preferably, a plurality of spaced connecting teeth are provided at the end of the abutting portion 13 near the receiving groove 14. That is, in this embodiment, connecting teeth can also be provided on the abutting portion 13. Specifically, the connecting teeth can be provided at a position of the abutting portion 13 near the receiving groove 14.

[0066] With this structure, during the connection between the rivet 1 and the plate, the connecting teeth are positioned near the contact portion 13 and the receiving groove 14, allowing the contact portion 13 to press against the plate material and embedding the connecting teeth into the plate material. This arrangement significantly improves the connection strength of the rivet 1.

[0067] A plate riveting structure, comprising:

[0068] First plate 2;

[0069] A second plate 3 in contact with the first plate 2, the first plate 2 having a first connecting hole 21, and the second plate 3 having a second connecting hole 31;

[0070] The rivet 1 connected to the first plate 2 passes through the first connection hole 21 and is inserted into the second connection hole 31;

[0071] The rivet 1 includes a main body 1, which includes a first end 111 and a second end 112. The first end 111 is provided with a flange 12. A connecting portion 121 is provided at an edge of the flange 12 away from the central axis. The flange 12 is embedded in the wall of the first plate 2 away from the second plate 3.

[0072] A contact portion 13 is provided between the first end portion 111 and the second end portion 112 , and the contact portion 13 contacts the inner wall of the first connection hole 21 ;

[0073] The vicinity of the second end 112 is recessed toward the middle axis to form a receiving groove 14 , and the abutting portion 13 presses against the wall of the second plate 31 and the second plate 2 , so that the material of the second plate 2 flows into the receiving groove 14 .

[0074] In this embodiment, those skilled in the art can rivet the rivet 1 with the first plate 2 and the second plate 3 .

[0075] Specifically, the first plate 2 is provided with a first connection hole 21, and the second plate 3 is provided with a second connection hole 31. The rivet is inserted into the first connection block 21 and the second connection hole 31. Then, the first plate 2 and the second plate 3 are riveted.

[0076] The main body 11 of the rivet 1 is inserted into the first connection hole 21, the second end 112 of the main body 11 passes through the first connection hole 21, and the second end 112 passes through the second connection hole 31. It can be understood that the second end 112 is inserted into the second connection hole 31 and does not pass through the second connection hole 31.

[0077] As can be seen from the above arrangement, the first plate 2 and the second plate 3 can be arranged to interfere with each other. The main body 11 of the rivet 1 is inserted through the first connection hole 21 of the first plate 2 and into the second connection hole 31 of the second plate 3. Preferably, the first plate 2 and the second plate 3 are parallel to each other, thereby making the connection between the main body 11 and the first plate 2 and the second plate 3 more stable.

[0078] According to the above configuration, the main body 11 is provided with a first end 111 and a second end 112, wherein the second end 112 does not penetrate the second connection hole 31. After riveting is completed, the first end 111 does not form a protrusion on the side wall of the first plate 2 away from the second plate 3.

[0079] The rivet 1 is configured to include a flange portion 12, an abutment portion 13, and a receiving groove 14. Specifically, the first end portion 111 of the main body 1 extends away from the central axis to form the flange portion 12. The flange portion 12 is embedded in the first plate 2 to achieve connection with the first plate 2.

[0080] Furthermore, a connecting portion 121 is provided on the flange portion 12. By providing the connecting portion 121 and the flange portion 13 together to be fixedly connected to the first plate 2, the rivet 1 can be effectively connected to the first plate 2.

[0081] The main body 11 is provided with a contact portion 13, which allows the rivet 1 to penetrate the first connection hole 21 and contact the inner wall of the first connection hole 21. The contact portion 13 and the inner wall of the first connection hole 21 effectively prevent relative sliding between the first plate 2 and the rivet 1 after riveting.

[0082] A receiving groove 14 is provided on the second end portion 112 of the main body 11, so that when the interference portion 13 of the main body 11 is squeezed with the hole wall of the second connecting hole 31 of the second plate 3, the material of the second plate 3 can flow into the receiving groove during the extrusion deformation process.

[0083] During the above process, the material of the second plate 3 flows into the receiving groove 14 and forms a structure that interferes with the inner wall of the receiving groove, thereby providing an anti-slip force for the riveting between the riveted component 1 and the second plate 3 .

[0084] In one implementation of this embodiment, preferably, the connecting portion 121 is configured as a structure in which multiple arc sections are connected, and the connecting portion 121 is embedded in the first plate 2. That is, according to Figure 4 The two adjacent arc surfaces can be curved toward the direction close to the middle axis and toward the direction away from the middle axis respectively. That is, the concave arc surface and the convex arc surface can be connected.

[0085] During the riveting process between the connecting portion 121, the flange portion 12, and the first plate 2, the connecting portion 121 and the material of the first plate 2 are squeezed, and the material of the first plate 2 is forced into the concave surface by the convex curved surface. This process creates a structure of mutual interference between the material of the first plate 2 and the connecting portion 121, thereby generating a force to resist rotation when the riveted component 1 is about to rotate.

[0086] In the above arrangement, the connection between the riveted member 1 and the first plate 2 and the second plate 3 can be made more stable. In particular, the connection portion 121 can provide a greater force to resist rotation, and the arrangement of the receiving groove can generate a force to prevent disengagement, thereby effectively completing the riveting.

[0087] In the above embodiment, by providing the abutment portion on the main body 11 of the rivet 1, an eccentric connection can be achieved between the first plate 2 and the second plate 3. That is, even if the first connection hole 21 and the second connection hole 31 on the first plate 2 and the second plate 3 are eccentrically arranged, the rivet 1 can still achieve a stable connection.

[0088] In one embodiment, the connection portion 121 may be further configured to include: preferably, the connection portion 121 has a first side facing the first plate 2, the first side being provided with a plurality of spaced connection teeth, and the plurality of connection teeth being embedded in the first plate.

[0089] With the above structure, the connecting portion 121 can be configured as a plurality of spaced connecting teeth, which can be embedded in the first plate 2, thereby completing the riveting between the riveted component 1 and the first plate 2.

[0090] The structure in which the connecting teeth are embedded in the first plate 2 can significantly improve the anti-rotation effect after the riveted member 1 is riveted to the first plate 2. That is, the engagement between the material of the first plate 2 and the adjacent connecting teeth generates a greater force to resist rotation.

[0091] In another optional embodiment, a plurality of spaced-apart connecting teeth can be provided at the end of the abutment portion 13 near the receiving groove 14. During connection between the rivet 1 and the second sheet 3, the connecting teeth are provided near the receiving groove 14 on the abutment portion 13, allowing the abutment portion 13 to be pressed against the material of the second sheet 3 and embedding the connecting teeth into the material of the second sheet 3. This arrangement can significantly improve the connection strength of the rivet 1.

[0092] Preferably, the outer wall of the rivet 1 is carburized to form a carburized layer. The rivet 1 is subjected to cold heading, heat treatment and surface treatment. The heat treatment can be conditioned or carburized, and the riveted parts can also be induction hardened; the heat treatment can be conditioned and applied to the connection of ordinary sheet metals. Carburization can also be performed, and the riveted parts can also be induction hardened. After these two heat treatments, high-strength plate connections can be achieved.

[0093] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Some industry standards or slightly modified implementations based on customized methods or implementations described in the embodiments can also achieve the same, equivalent, or similar implementation effects as the above embodiments, or predictable implementation effects after modification. Examples that apply these modified or modified data acquisition, processing, output, judgment methods, etc. can still fall within the scope of optional implementation schemes of this application.

[0094] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
