Description

Technical Field

[0001] This utility model relates to the field of vehicle metal parts, specifically to a butterfly-shaped press-fit assembly. Background Technology

[0002] In the field of vehicle manufacturing, irregularly shaped and small-sized metal press-fit parts are widely used. They are usually composed of a bent metal base and a press-fit nut, used to achieve precise connection between different parts.

[0003] In these types of press-fit parts, the nuts are often directly press-fitted into the flat area or simple bend of the metal substrate. Due to the limitations of small-sized structures, the support structure after the nuts are press-fitted lacks stability. Especially under conditions of continuous vibration generated by vehicle movement, the nuts are prone to loosening and shifting, leading to a decrease in connection reliability.

[0004] Although some designs attempt to optimize the riveting process, they do not improve the support environment of the nuts from the perspective of the base structure. As a result, it is still difficult to solve the problem of positional stability during long-term use, which may lead to component connection failure and affect the overall performance and safety of the vehicle. Utility Model Content

[0005] The problem to be solved by this utility model is to provide a butterfly-shaped press-fit assembly.

[0006] To solve the above problems, this utility model provides a butterfly-shaped press-fit assembly. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: A butterfly-shaped press-fit assembly includes: a three-dimensional component, comprising a first flat plate portion, with a second flat plate portion integrally and vertically fixed to both ends of the first flat plate portion; two planar components, symmetrically located on both sides of the three-dimensional component, wherein the planar components, the first flat plate portion, and the second flat plate portion are all vertically fixed to each other; and a nut, press-fitted to the first flat plate portion of the three-dimensional component; wherein the nut is located within the three-dimensional concave space enclosed by the first flat plate portion, the second flat plate portion, and the planar components.

[0007] As a further improvement of this utility model, the first flat plate portion and the second flat plate portion are respectively recessed on the same side to form a rectangular notch and a corner notch, and the two vertical adjacent sides of the planar component are respectively protruding with a first rectangular protrusion and a second rectangular protrusion. The first rectangular protrusion is fitted with the rectangular notch in a concave-convex manner, and the second rectangular protrusion is fitted with the corner notch in a concave-convex manner.

[0008] As a further improvement of this utility model, the recessed depth of the rectangular notch and the internal corner notch is equal to the thickness of the planar part; and / or the protrusion height of the first rectangular protrusion and the second rectangular protrusion is equal to the thickness of the three-dimensional part.

[0009] As a further improvement of this utility model, there is an outer rounded corner at the junction of the two adjacent sides of the planar part where the first rectangular convex part and the second rectangular convex part are located.

[0010] As a further improvement of this utility model, the edge of the planar component has a convex back, and the convex back has an outward convex direction opposite to that of the first rectangular convex portion.

[0011] As a further improvement of this utility model, the edge of the first flat plate portion has a recessed notch, and the centroid of the recessed notch is located on the mirror symmetry plane of the three-dimensional component.

[0012] As a further improvement of this utility model, the thickness of the planar part is greater than the thickness of the three-dimensional part.

[0013] As a further improvement of this utility model, the three-dimensional part is welded and assembled with the planar part, and the weld between the three-dimensional part and the planar part is located in the three-dimensional internal corner space.

[0014] The beneficial technical effects of using the butterfly-shaped press-fit assembly of this application are: The basic frame is formed by the first flat plate of the three-dimensional component and the second flat plate that is perpendicular to both ends. Combined with the flat components that are symmetrical on both sides and perpendicular to the first two, a stable spatial structure is constructed. At the same time, the nut is confined within the three-dimensional concave space enclosed by the three components. This space can provide multi-directional structural support for the nut, effectively improving the problem of insufficient nut support stability in traditional small-sized press-fit components and reducing the possibility of nut loosening and displacement caused by vehicle vibration.

[0015] The three-dimensional recessed space forms a semi-enclosed state for the nut, which can prevent accidental contact from affecting the nut and avoid the nut's connection performance from deteriorating due to external environmental factors, thus improving the nut's protective effect during long-term use.

[0016] The butterfly-shaped press-fit assembly of this application can be used for connecting internal brackets in automotive dashboards and center consoles. It is an internal connecting bracket, with one end securing the dashboard frame and the other end connecting to the center console frame. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, please refer to Figures 1 to 6 A butterfly-shaped press-fit assembly includes: a three-dimensional component 1, comprising a first flat plate portion 11, with second flat plate portions 12 integrally and vertically fixed to both ends of the first flat plate portion 11, the three-dimensional component 1 being U-shaped; two planar components 2, symmetrically located on both sides of the three-dimensional component 1, the planar components 2, the first flat plate portion 11, and the second flat plate portion 12 being perpendicularly fixed to each other; and a nut 3, press-fitted to the first flat plate portion 11 of the three-dimensional component 1. The nut 3 is located within the three-dimensional concave space enclosed by the first flat plate portion 11, the second flat plate portion 12, and the planar components 2. That is, the nut 3 is located within the triangular pyramidal space enclosed by the first flat plate portion 11, the second flat plate portion 12, and the planar components 2.

[0021] The first flat plate 11 is narrow in the middle and wide at both ends.

[0022] Two planar parts 2 coincide on the same spatial plane, and the first flat plate part 11 has a through hole 13 coaxial with the nut 3.

[0023] To clearly demonstrate 3D part 1, compared to Figure 4 , Figure 3 Nut 3 is hidden inside.

[0024] The beneficial effects of adopting the above technical solution are: the overall shape of the riveting assembly resembles a bow. The final three-dimensional component 1 and the flat component 2 together form a butterfly-shaped spatial three-dimensional component. This spatial three-dimensional component has two three-dimensional internal corners, each formed by three perpendicular surfaces. The nut 3 is fixed near these internal corners. Due to the three-dimensional structure of the internal corners, the structural strength of the entire riveting assembly is greatest at this location, resulting in optimal dimensional stability and the best semi-enclosed protection. Therefore, the nut 3 riveted at this location is also less prone to loosening and provides good protection. This effectively improves the problem of insufficient nut support stability in traditional small-sized riveting components, reduces the possibility of nut 3 loosening or shifting due to vehicle vibration, and protects nut 3 from external environmental influences through its semi-enclosed state.

[0025] In other embodiments of this utility model, such as Figure 1 As shown, rectangular notches 14 and internal corner notches 15 are respectively recessed on the same side of the first plate portion 11 and the second plate portion 12, as shown. Figure 2 As shown, the two vertical adjacent sides of the planar part 2 have a first rectangular protrusion 21 and a second rectangular protrusion 22 respectively. The first rectangular protrusion 21 is fitted with the rectangular notch 14 in a concave-convex manner, and the second rectangular protrusion 22 is fitted with the internal corner notch 15 in a concave-convex manner.

[0026] In another embodiment, such as Figure 5 As shown, both the rectangular notch 14 and the internal corner notch 15 have a three-quarter circular notch 4 at their internal corners. The roots of the first rectangular protrusion 21 and the second rectangular protrusion 22 also have three-quarter circular notches 4 on both sides. This ensures that there are no burrs when they are assembled with each other, thus guaranteeing proper assembly. It also facilitates solder filling during welding.

[0027] The beneficial effects of adopting the above technical solution are: it makes the connection between the three-dimensional part 1 and the flat part 2 more precise and firm, avoids assembly misalignment, and at the same time, the three-quarter circular notch 4 at the notch helps to eliminate burrs, ensures proper assembly, and provides space for solder filling during welding, thereby improving the overall assembly quality.

[0028] In some other embodiments of this utility model, the recessed depth of the rectangular notch 14 and the internal corner notch 15 is equal to the thickness of the planar part 2. The protrusion height of the first rectangular protrusion 21 and the second rectangular protrusion 22 is equal to the thickness of the three-dimensional part 1.

[0029] The beneficial effects of adopting the above technical solution are: this size matching ensures the tightness of the concave-convex assembly, so that the surface of the three-dimensional part 1 and the flat part 2 is flat and without gaps after they are combined, which enhances the stability and connection strength of the overall structure and reduces the risk of loosening.

[0030] In some other embodiments of this utility model, there is an outer rounded corner 24 at the junction of the two adjacent sides of the planar member 2 where the first rectangular protrusion 21 and the second rectangular protrusion 22 are located.

[0031] The beneficial effects of adopting the above technical solution are: the outer rounded corners also serve to avoid the boundary line between the first flat plate part 11 and the second flat plate part 12, ensuring that the three-dimensional part 1 and the flat part 2 can be properly engaged. This prevents structural interference, ensures that the three-dimensional part 1 and the flat part 2 can be smoothly engaged, and improves assembly efficiency and accuracy.

[0032] In some other embodiments of this utility model, the edge of the planar member 2 has a convex back 25, and the convex back 25 and the first rectangular convex part 21 have opposite convex directions.

[0033] The beneficial effect of adopting the above technical solution is that the raised convex back 25 widens the size of the flat part 2 here, further improving the anti-collision performance.

[0034] In some other embodiments of the present invention, the edge of the first flat plate portion 11 has a recessed notch 16, and the centroid of the recessed notch 16 is located on the mirror symmetry plane of the three-dimensional member 1.

[0035] The beneficial effect of adopting the above technical solution is that the recessed notch 16 is used for alignment and assembly with other external parts.

[0036] In some other embodiments of this utility model, the thickness of the planar part 2 is greater than the thickness of the three-dimensional part 1.

[0037] The beneficial effects of adopting the above technical solution are: the thickness difference makes the planar part 2, as the main support surface, have a stronger load-bearing capacity, while the thinner three-dimensional part 1 helps to reduce the overall weight, optimize the strength-to-weight ratio of the assembly, and is suitable for application scenarios with lightweight and high strength requirements.

[0038] In some other embodiments of this utility model, the three-dimensional part 1 and the flat part 2 are welded together, and the weld between the three-dimensional part 1 and the flat part 2 is located in the three-dimensional internal corner space, that is, in the triangular pyramid space that is partially surrounded by the first flat plate part 11, the second flat plate part 12, and the flat part 2.

[0039] The beneficial effects of adopting the above technical solution are: the three-dimensional part 1 and the flat part 2 are assembled by welding, and the weld is located in the three-dimensional internal corner space, that is, in the triangular pyramid space that is partially enclosed by the first flat plate part 11, the second flat plate part 12 and the flat part 2. This arrangement protects the weld from direct external impact and corrosion, reduces the risk of wear, and at the same time uses the internal corner structure to enhance the firmness of the welding point and extend the service life of the assembly.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
