Description

Technical Field

[0001] This utility model belongs to the technical field of fixed filler components, specifically referring to a slotted fixed filler component for the inner wall of automotive exterior parts. Background Technology

[0002] In the existing technology, automotive exterior parts are made by one-piece molding. During the design process, the injection molding material on the inner wall of the automotive exterior parts results in an inclined structure at the bottom. When the nut is inserted into the injection molding material, it cannot fit the bottom of the injection molding material due to the inclined structure, resulting in the nut not being stable enough. To solve this problem, a snap-fit ​​filling part for the inner wall of automotive exterior parts is designed. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a slotted fixing filler for the inner wall of automotive exterior parts, which effectively solves the problem of surface shrinkage marks after molding.

[0004] The technical solution adopted by this utility model is as follows: This utility model proposes a slotted fixing filler for the inner wall of an automotive exterior trim part, including a base. The top edge of the base is integrally formed with an outer ring. A nut is inserted and pulled onto the outer ring. The nut is inserted into the outer ring, and the top of the nut is parallel to and above the inner hole of the injection molding material. The outer ring is composed of side pieces and spacer grooves arranged at intervals and evenly distributed along the circumference. An inner clip is integrally formed on the inner wall of the next set of side pieces after every set of side pieces, and the inner clip is set in the form of a trapezoidal block.

[0005] As an improvement to this solution, the outer ring has grooves evenly distributed along the axial direction on its sidewall, and the nut has a countersunk hole at its center.

[0006] As an improvement to this solution, the bottom edge of the nut is chamfered to facilitate the insertion of the nut into the outer ring via the inner retainer. At the same time, the inner retainer engages with the lowest set of grooves.

[0007] As an improvement to this solution, the bottom of the base is a downward-sloping structure, which is used to fit into the inner hole of the injection molding material filled into the inner wall of the automotive exterior trim. The base fits into the bottom of the slope of the inner hole of the injection molding material, and the outer ring fits into the inner wall of the inner hole of the injection molding material.

[0008] The beneficial effects of this utility model by adopting the above structure are as follows:

[0009] The nut is inserted into the inner side of the outer ring, and the nut is clamped by the side piece and the inner clamping piece. The filling function is achieved by filling the inner hole of the injection molding material through the fixed filler, thus solving the problem of surface shrinkage marks after molding. The overall structure is simple and low-cost, while achieving stable and reliable use. Attached Figure Description

[0016] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a slotted fixing filler for the inner wall of an automotive exterior trim, including a base 1, an outer ring 2 integrally formed on the top edge of the base 1, a nut 3 inserted into the outer ring 2, the nut 3 being inserted into the outer ring 2, and the top of the nut 3 being parallel to and above the inner hole of the injection molding material.

[0019] The outer ring 2 is composed of side pieces 4 and spacer grooves 6 arranged at intervals and evenly distributed along the circumference. An inner clamping piece 5 is integrally formed on the inner wall of the next set of side pieces 4 after every set of side pieces 4, and the inner clamping piece 5 is set in a trapezoidal block.

[0020] like Figure 4 As shown, grooves 7 are evenly distributed along the axial direction on the side wall of the outer ring 2, and a countersunk hole 8 is provided in the center of the nut 3. The bottom edge of the nut 3 is chamfered to facilitate the insertion of the nut 3 into the outer ring 2 through the inner retainer 5. At the same time, the inner retainer 5 is engaged in the bottommost set of grooves 7.

[0021] like Figure 5 The bottom of the base 1 is a downward-sloping structure, which is used to fit into the inner hole of the injection molding material filled into the inner wall of the automotive exterior trim. The base 1 fits into the bottom of the slope of the inner hole of the injection molding material, while the outer ring 2 fits into the inner wall of the inner hole of the injection molding material.

[0022] In practical use, by inserting the nut 3 into the inner side of the outer ring 2, under the action of the chamfer at the bottom edge of the nut 3, the bottom of the nut 3 can be inserted to the upper end face of the base 1 along the inclined surface of the inner clip 5. Then, the inner clip 5 resets and is inserted into the groove 7 of the nut 3. At this time, the nut 3 is clamped by the cooperation of the side piece 4 and the inner clip 5. The base 1 and the outer ring 2 are used to fill the inner hole of the injection molding material on the inner wall of the automotive exterior parts to achieve leveling, so as to stabilize the nut 3 and solve the problem of surface shrinkage marks after molding. The above is the entire process of using the snap-fit ​​fixing filler for the inner wall of the automotive exterior parts.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
