[0008] The riveting part is disposed below the stepped surface. The riveting part includes a discharge part, a receiving part, and a guide part arranged sequentially along the axial direction. The diameter of the discharge part is smaller than the diameter of the main body part, and the discharge part forms a discharge step with the stepped surface. The outer diameter of the guide part is smaller than the outer diameter of the discharge part. The diameter of the receiving part gradually increases from the discharge part to the guide part. A receiving groove for accommodating material flowing on the plate due to deformation is formed between the receiving part and the discharge part.

The outer diameter of the second shaft portion is smaller than the outer diameters of the second head portion and the base portion. The second head portion, the second shaft portion, and the base portion form an I-shaped structure.

[0011] Furthermore, in the aforementioned press-fit connector, the mounting portion has a knurled tooth, polygonal, or oblique conical structure.

[0012] Furthermore, in the aforementioned press-fit connector, the outer wall of the discharge section is provided with knurled teeth.

[0013] Furthermore, in the aforementioned press-fit connector, the main body is a solid or hollow structure.

[0014] This application also provides a connection structure, including:

[0015] The plate has a first plate surface and a second plate surface that are parallel to each other. The first plate surface has a first through hole that is connected to the mounting part, and the second plate surface has a second through hole that is connected to the riveting part. The diameter of the first through hole is larger than the diameter of the second through hole.

[0016] As described above, before the press-fit connector is connected to the plate, the second end of the main body passes through the first through hole and is placed inside the plate, and the stepped surface has a gap with the second plate surface. The guide part is placed inside the second through hole, the discharge part is placed above the second plate surface and has a gap with the second plate surface, the outer diameter of the discharge part is larger than the diameter of the second through hole, and the mounting part is placed on the upper surface of the first plate surface.

[0034] Example 1

[0035] Reference Figures 1 to 7 This application provides a press-fit connector, comprising:

[0036] The main body 1 has a first end and a second end along its axial direction. The first end is provided with a mounting part 2, the upper surface of which is provided with a mounting surface 3, and the bottom of the second end is provided with a stepped surface 4.

[0037] The riveting part 5 is disposed below the stepped surface 4. The riveting part 5 includes a discharge part 51, a receiving part 52 and a guide part 53 arranged sequentially along the axial direction. The diameter of the discharge part 51 is smaller than the diameter of the main body part 1, and the discharge part 51 and the stepped surface 4 form a discharge step. The outer diameter of the guide part 53 is smaller than the outer diameter of the discharge part 51. The diameter of the receiving part 52 gradually increases from the discharge part 51 to the guide part 53. A receiving groove for accommodating the material flowing on the plate due to deformation is formed between the receiving part 52 and the discharge part 51.

[0038] The first connecting part is formed by the guide part 53 and the first shaft part 6 and the first head part 7 arranged sequentially below the guide part 53, and the guide part 53, the first shaft part 6 and the first head part 7 form an I-shaped structure.

[0039] The diameter of the material-containing section 52 gradually increases from the discharge section 51 to the guide section 53. A material-containing groove is formed between the material-containing section 52 and the discharge section 51 to accommodate the material flowing on the sheet due to deformation. The material-containing groove accommodates the material flowing in the sheet during extrusion deformation. The anti-pull-out force structure formed by the material-containing section 52 allows the connected sheet to form a blocking structure with the material-containing section 52, thereby giving the connected sheet the ability to prevent it from coming off.

[0040] Specifically, further, based on the above embodiment, a second connecting part is provided above the mounting part 2. The second connecting part includes a second head 8, a second shaft 9, and a base 10 arranged sequentially along the axial direction. The base 10 is disposed on the mounting surface 3. The outer diameter of the base 10 is smaller than the outer diameter of the mounting part 2. The outer diameter of the second shaft 9 is smaller than the outer diameters of the second head 8 and the base 10. The second head 8, the second shaft 9, and the base 10 form an I-shaped structure. Both the first connecting part and the second connecting part are I-shaped structures, forming a double-press riveted I-shaped nail structure, which enables rapid installation and rapid disassembly, and can be used for installation and disassembly in new energy battery pack battery modules.

[0041] With the above structure, both the first connecting part and the second connecting part are I-shaped positioning, which can realize the function of quick assembly and disassembly, and can restrict the external mounting parts from moving up and down along the axis. The first shaft part 6 and the second shaft part 9 can be quickly installed, positioned and disassembled with the corresponding holes. The corresponding holes can be keyholes, V-holes or U-holes or other structures.

[0042] Specifically, in this embodiment, the mounting part 2 is a knurled, polygonal, or oblique conical structure. The mounting part 2 facilitates guided installation, eliminates radial clearance, and provides additional thrust and torque resistance; in other embodiments, the mounting part 2 may also be configured as a cylindrical structure.

[0043] Specifically, in this embodiment, the outer wall of the discharge section 51 is provided with knurled teeth. The knurled tooth structure of the discharge section 51 allows it to be pressed into the material of the sheet metal during the connection process. The knurled tooth structure has intermittent gaps, forming an anti-torque structure, allowing the material of the sheet metal to be pressed into these gaps, thus enabling the connected sheet metal to resist rotation.

[0044] Specifically, in this embodiment, the main body 1 is a solid or hollow structure. (Refer to...) Figure 4 and Figure 5 The upper part of the main body 1 can be a hollow structure, as shown in the reference. Figure 6 and Figure 7 The main body 1 can be divided into upper and lower parts, both of which are hollow structures. The hollow structure assembly can achieve the effect of reducing the weight of the overall press-fit connection, making the application of press-fit connections more flexible and making the installation of batteries in new energy vehicles more convenient.

[0045] Example 2

[0046] Reference Figures 1 to 10 This embodiment also provides a connection structure using the press-fit connectors described above, including:

[0047] The plate has a first plate surface 11 and a second plate surface 12 that are parallel to each other. The first plate surface 11 has a first through hole 13 that is connected to the mounting part 2. The second plate surface 12 has a second through hole 14 that is connected to the pressing part. The diameter of the first through hole 13 is larger than the diameter of the second through hole 14. As described in Embodiment 1, before the pressing part is connected to the plate, the second end of the main body 1 passes through the first through hole 13 and is placed inside the plate. The stepped surface 4 has a gap with the second plate surface 12. The guide part 53 is placed inside the second through hole 14. The discharge part 51 is placed above the second plate surface 12 and has a gap with the second plate surface 12. The outer diameter of the discharge part 51 is larger than the diameter of the second through hole 14. The mounting part 2 is placed on the upper surface of the first plate surface 11.

[0048] Specifically, in this embodiment, the connection structure includes: a plate having a first plate surface 11 and a second plate surface 12 parallel to each other; the first plate surface 11 having a first through hole 13 connected to the mounting part 2; the second plate surface 12 having a second through hole 14 connected to the pressing part; and the diameter of the first through hole 13 being larger than the diameter of the second through hole 14; as in the pressing connector of Embodiment 1, the second end of the main body 1 passes through the first through hole 13 and is placed inside the plate, and the stepped surface 4 abuts against the second plate surface 12; under the pressing action of the stepped surface 4, part of the material in the plate inside the second through hole 14 deforms and flows into the material receiving groove.

[0049] Using the above structure, refer to Figure 8 First, the guide part 53 is positioned inside the second through hole 14. Then, using the upper and lower parallel molds, riveting pressure is applied to the mounting surface 3, and the main body 1 applies the riveting pressure to the riveting part 5 until the stepped surface 4 is in contact with the second plate surface 12. The material in the riveting part 5 and the second through hole 14 are interlocked and connected. Under the pressure of the stepped surface 4, part of the material in the plate inside the second through hole 14 deforms and flows into the material receiving groove. At the same time, the outer wall of the discharge part 51 is provided with knurled teeth. The knurled tooth structure of the discharge part 51 can be squeezed into the material of the plate during the connection process. There are gaps in the knurled tooth structure, which can form an anti-torque structure. The material of the plate can be squeezed into the gaps, so that the plate has anti-rotation ability after connection. After the press-fit connector is connected to the plate, the connection structure can achieve stable anti-push and anti-torque capabilities. The connection structure in this embodiment can be a single-sided I-beam structure or a double-sided I-beam structure, see reference. Figure 9 When the press-fit connector is a single-sided I-shaped nail, it forms a single-sided I-shaped structure after being connected to the sheet metal; refer to Figure 10 When the press-fit connector is a double-sided I-shaped nail, it forms a double-sided I-shaped structure after being connected to the plate. The I-shaped structure can achieve quick assembly and disassembly with external parts, and can achieve bidirectional positioning installation and disassembly in one step.

[0050] Specifically, in this embodiment, the height of the guide portion 53 along the axial direction is greater than or equal to the thickness of the second plate surface 12, which can realize the connection of the press-fit connector to the second plate surface 12 in the plate.
