Description

Technical Field

[0001] This utility model relates to the field of power battery housing technology, specifically, it is a riveting mechanism for riveting nuts of power battery housings. Background Technology

[0002] The battery pack housing is a crucial component used to house and protect the battery packs used in electric or hybrid vehicles. It not only provides physical protection against external shocks, vibrations, moisture, and dust, but also must possess excellent heat dissipation capabilities to ensure the battery remains within a suitable temperature range during operation, thereby improving battery efficiency and lifespan.

[0003] In the existing technology, the rivet support for the rivet nut of the power battery box is installed and removed from the bottom by locking bolts every time it is replaced. The operation is cumbersome, time-consuming and labor-intensive. The replacement efficiency of the rivet support is low and it is also easy to have bad teeth.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a riveting mechanism for power battery housing riveting nuts that is simple to operate, has high replacement efficiency, and is less prone to tooth damage.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A riveting mechanism for a power battery housing riveting nut includes a base and a fixing pin. The first end of the base is provided with a vertical through hole and a horizontal blind hole. The vertical through hole is connected to the horizontal blind hole, and the fixing pin is movably inserted in the horizontal blind hole.

[0008] As a further embodiment of this utility model, several hanging brackets are provided on both sides of the base, and each hanging bracket is provided with a hanging hole.

[0009] As a further embodiment of this invention, each of the hanging holes has a different size.

[0010] As a further embodiment of this invention, one side wall of the vertical through hole is configured as a planar anti-fouling wall.

[0011] As a further embodiment of this utility model, an ear plate is provided at the end of the fixing pin away from the base.

[0012] As a further embodiment of this utility model, the fixing pin is fitted with a sleeve, the sleeve is inserted into the horizontal blind hole, and the outer end face of the sleeve is an inclined surface.

[0013] As a further embodiment of this utility model, the outer circumferential surface of the sleeve is provided with a guide protrusion along the axial direction, and the horizontal blind hole is provided with a guide groove that matches the guide protrusion.

[0014] As a further embodiment of this utility model, the fixing pin includes a large diameter section and a small diameter section integrally formed from the large diameter section.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Due to the aforementioned structural design, a vertical through hole and a horizontal blind hole are connected at the first end of the base. A fixing pin is movably inserted into the horizontal blind hole. During operation, the corresponding rivet support for the required rivet nut is inserted into the vertical through hole of the base. The fixing pin passes through the through hole on the rivet support to the bottom of the horizontal blind hole, ensuring that the rivet support is stable and does not wobble, facilitating the rivet nut and the product to begin riveting. If it is necessary to replace the rivet support of a different specification, simply pull out the fixing pin, remove the current rivet support and replace it with the corresponding rivet support to start the next riveting step. This design is not only simple to operate and highly efficient, but also less prone to tooth damage. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. It should be pointed out that all accompanying drawings are exemplary representations. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0032] like Figure 1-3As shown, this application discloses a riveting mechanism for a power battery box riveting nut, comprising a base 10 and a fixing pin 20. The first end of the base 10 is provided with a vertical through hole 11 and a horizontal blind hole 12. The vertical through hole 11 and the horizontal blind hole 12 are connected. The fixing pin 20 is movably inserted into the horizontal blind hole 12. The fixing pin 20 includes a large diameter section 21 and a small diameter section 22 integrally formed from the large diameter section 21. During operation, the riveting support corresponding to the required riveting nut is inserted into the vertical through hole 11 of the base. The small diameter section 22 passes through the through hole on the riveting support to the bottom of the horizontal blind hole 12, ensuring that the riveting support is stable and does not wobble, facilitating the riveting of the nut and the product. If it is necessary to replace the riveting support with a different specification, simply pull out the fixing pin 20, remove the current riveting support and replace it with the corresponding riveting support to start the next riveting step. This not only makes the operation simple and the replacement efficiency high, but also reduces the risk of damaged teeth.

[0033] As a preferred embodiment, the base 10 is provided with six hanging brackets 30 on both sides, the six hanging brackets 30 are arranged in pairs facing each other, and each hanging bracket 30 is provided with a hanging hole 31. Each hanging hole 31 is of different sizes and is used to place rivet supports of different specifications.

[0034] Specifically, one side of the groove wall of the vertical through hole 11 is set as a planar anti-fake wall 111, which corresponds to and cooperates with the anti-fake surface of the press-fit post, so that the press-fit post will not rotate after being inserted into the vertical through hole 11; at the same time, the through hole on the press-fit post corresponds to the horizontal blind hole, so that the fixing pin 20 can pass through the through hole on the press-fit post to the bottom of the horizontal blind hole.

[0035] Specifically, the end of the fixing pin 20 away from the base 10 is provided with an ear plate 23, that is, the ear plate 23 is provided on the large diameter section 21, so that external force can be applied to the ear plate 23 to pull the fixing pin 20 out of the horizontal blind hole 12.

[0036] Specifically, the fixing pin 20 is fitted with a sleeve 40, which is inserted into the horizontal blind hole 12. The outer end face of the sleeve 40 is inclined. When the large diameter section 21 is inserted into the sleeve 40, the ear plate 23 is oriented towards the lowest end of the inclined surface. An external force is applied to the ear plate 23, causing the fixing pin 20 to rotate. With the ear plate 23 blocked by the periphery of the inclined surface, the fixing pin 20 is pulled out of the sleeve 40, thus making it easier and less strenuous to pull the fixing pin 20 out of the horizontal blind hole 12.

[0037] Specifically, the outer circumferential surface of the sleeve 40 is provided with a guide protrusion 41 along the axial direction, and a guide groove 121 adapted to the guide protrusion 41 is provided in the horizontal blind hole 12. The sleeve 40 is prevented from rotating in the horizontal blind hole 12 by the cooperation between the guide protrusion 41 and the guide groove 121.

[0038] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high replacement efficiency, and high product yield.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
