[0027] like Figures 1-5 As shown, the snap-fit ​​nut 100 provided by this utility model is used to fix the part to be assembled 300 on the base 200. Both the base 200 and the part to be assembled 300 have through holes for the bolt 400 to pass through.

[0028] The snap-fit ​​nut 100 includes a snap-fit ​​portion, which comprises a first snap-fit ​​plate 110 and a second snap-fit ​​plate 120. In a first direction, a first side of the first snap-fit ​​plate 110 and a first side of the second snap-fit ​​plate 120 are connected by a U-shaped transition portion 130. The integral structure formed by the connection of the first snap-fit ​​plate 110, the U-shaped transition portion 130, and the second snap-fit ​​plate 120 is U-shaped. An opening is formed between the second side of the first snap-fit ​​plate 110 and the second snap-fit ​​plate 120, with the first side and the second side representing opposite directions in the first direction. Due to the elasticity of the U-shaped transition portion 130, as the opening of the first snap-fit ​​plate 110 and the second snap-fit ​​plate 120 increases, the first snap-fit ​​plate 110 and the second snap-fit ​​plate 120 generate a clamping force that moves in the direction of each other.

[0029] The first snap-fit ​​plate 110 has a first through hole 111 at the middle position, and the inner wall of the first through hole 111 has an internal thread; the second snap-fit ​​plate 120 has a second through hole 121, and the second through hole 121 is coaxially arranged with the first through hole 111 so that the bolt 400 passes through the second through hole 121 and is threadedly connected to the first through hole 111.

[0030] The first snap-fit ​​plate 110 and the second snap-fit ​​plate 120, which are elastically connected, can clamp onto both sides of the parts 300 to be assembled, thereby forming a snap-fit ​​and increasing stability. The bolt 400 passes through one side of the fixed base 200, then through one side of the second snap-fit ​​plate 120, and after passing through the second through hole 121, it is threaded into the internal thread of the first through hole 111. After tightening, the base 200, the snap-fit ​​nut 100, and the parts 300 to be assembled are connected as a whole. After the bolt 400 is tightened, the first snap-fit ​​plate 110 moves towards the base 200, thereby clamping the parts 300 to be assembled between the first snap-fit ​​plate 110 and the second snap-fit ​​plate 120. This stable snap-fit ​​prevents the nut from falling off and the bolt 400 from loosening, improving the assembly quality and performance of the automotive fan.

[0031] Furthermore, the U-shaped transition portion 130 is provided with an opening groove 131, which is easy to bend and shape, and can also ensure the elasticity of the first snap-fit ​​plate 110 and the second snap-fit ​​plate 120.

[0032] Both the first snap-fit ​​plate 110 and the second snap-fit ​​plate 120 are generally rectangular. In the second direction, the third and fourth edges of the first snap-fit ​​plate 110 are provided with notches and grooves 112 for snapping with the protrusions 310 on the part to be assembled 300. The third and fourth edges are opposite directions of the second direction.

[0033] like Figure 1 and Figure 4 As shown, the component to be assembled 300 passes through the opening of the snap-fit ​​nut 100, and the protrusion abuts against the first snap-fit ​​plate 110. When the protrusion moves to the notch 112, the protrusion protrudes from the notch 112 and snaps into the notch 112, preventing the component to be assembled 300 from continuing to move in the first direction. The first snap-fit ​​plate 110 and the component to be assembled 300 form a reverse engagement to prevent the nut from falling off the component to be assembled 300.

[0034] like Figure 3 As shown, in order to increase the threaded connection area, the first snap-fit ​​plate 110 is provided with a tube body 500 that is coaxial with the first through hole 111 and has the same inner diameter on the side facing away from the second snap-fit ​​plate 120. The hollow areas of the first through hole 111 and the tube body 500 are provided with continuous internal threads.

[0035] like Figure 3As shown, a guide structure is provided at the opening to guide the component 300 to be assembled into the opening, facilitating the opening to be opened and allowing the component 300 to enter between the first snap-fit ​​plate 110 and the second snap-fit ​​plate 120. Specifically, the guide structure includes a guide edge 113 disposed on the edge of the second side of the first snap-fit ​​plate 110, with the distance between the guide edge 113 and the second snap-fit ​​plate 120 gradually decreasing from the second side towards the first side. The flared opening structure facilitates the insertion of the component 300.

[0036] like Figure 3 As shown, from the second side toward the first side, the distance between the first snap-fit ​​plate 110 and the second snap-fit ​​plate 120 gradually increases, thereby increasing the clamping force after the assembly 300 is inserted.

[0037] The second snap-fit ​​plate 120 is provided with an arc-shaped through groove 122 surrounding the second through hole 121 on the outer side. The portion of the second snap-fit ​​plate 120 located between the arc-shaped through groove 122 and the second through hole 121 forms an elastic pressing part.

[0038] When bolt 400 is tightened, the second snap-fit ​​plate 120 is pulled toward the side of the first snap-fit ​​plate 110, the U-shaped transition part 130 deforms, and the arc-shaped through groove 122 moves away from the second through hole 121 and away from the base 200. Conversely, the arc-shaped through groove 122 is firmly abutted against the base 200 on the side facing the second through hole 121. The inner area of ​​the arc-shaped through groove 122 can generate elastic deformation, generating pre-tightening force to prevent bolt 400 from loosening.

[0039] The automotive fan mounting assembly provided by this utility model includes the aforementioned snap-fit ​​nut 100.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
