Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a front bumper and upper grille riveted structure that can be smoothly demolded, increase reliability, and reduce manufacturing costs.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A front bumper and upper grille riveted structure comprises a front bumper body and an upper grille body, wherein both ends of the front bumper body are bumper corners, and both ends of the upper grille body are grille corners, and the bumper corners and grille corners are arranged opposite to each other;

[0006] The bumper has a rotatable connecting piece at the tip corner, and a rivet hole insert is fixed at the grille tip corner. Both the connecting piece and the rivet hole insert are provided with rivet holes, and the connecting piece and the rivet hole insert are riveted together by rivets.

[0007] Wherein, the rivet is a flower rivet.

[0008] Wherein, an oblique groove is provided at the sharp corner of the bumper, and a limiting block capable of plugging and cooperating with the oblique groove is fixed at the sharp corner of the grille.

[0009] Wherein, the front bumper body is made of PP material, and the upper grille body is made of ABS material.

[0010] Wherein, the front bumper body and the upper grille body are fixedly connected by screws.

[0011] Wherein, the front bumper body and the upper grille body are connected via a snap-fit ​​structure.

[0012] The buckle structure comprises a tongue fixedly mounted on the upper grille body, the tongue is provided with a slot, the front bumper body is provided with a channel allowing the tongue to pass through, the channel is protruding with a block capable of engaging with the slot.

[0013] In summary, the riveted structure of the front bumper and the upper grille has a simple layout, ingenious design, and reasonable riveting points. The focus is on selecting the appropriate position to design the riveted structure, which can not only ensure the smooth demolding of the two parts, but also increase the connection strength of the riveted structure. The simplest injection molding + riveting process is adopted to increase the local strength and prevent local deformation in the structure. This structure only needs to invest in simple riveting tools to achieve a long-term and stable manufacturing process for the product. Compared with the structure of the original modeling consideration, it reduces a pair of welding bracket injection molds and a pair of welding tooling and equipment, increases the reliability of the product, greatly reduces the product manufacturing cost, and reduces project expenses.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0022] like Figure 1-7As shown, a front bumper and upper grille riveted structure comprises a front bumper body 1 and an upper grille body 2, wherein the two ends of the front bumper body are bumper corners, and the two ends of the upper grille body are grille corners, and the bumper corners and grille corners are arranged opposite to each other;

[0023] The bumper corner has a rotatable connecting piece 3, and the grille corner is fixed with a rivet hole insert 4. Both the connecting piece and the rivet hole insert are provided with rivet holes 31, and the connecting piece and the rivet hole insert are riveted together by rivets 5.

[0024] In a specific implementation, the rivet is a blooming rivet.

[0025] In a specific implementation, an oblique groove 32 is provided at the sharp corner of the bumper, and a limiting block 6 capable of plugging and cooperating with the oblique groove is fixed at the sharp corner of the grille.

[0026] In a specific implementation, the front bumper body is made of PP material, and the upper grille body is made of ABS material.

[0027] During specific implementation, the front bumper body and the upper grille body are fixedly connected by screws 7 .
