AI Technical Summary
The existing electric tricycles have problems with loose fit between plastic parts, large gaps, poor appearance, and high cost of high-precision molds.
The outer shell uses an injection-molded stud on the inside of the outer shell and an injection-molded recess on the inside of the inner shell for fastening. The two sides of the outer shell are snapped into the inner shell and fastened by self-tapping screws on the convex and concave plates, which enhances the connection strength between the plastic parts.
It reduces gaps between plastic parts, improves the overall appearance of the vehicle, enhances product quality, and reduces the investment cost of high-precision molds.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a tricycle plastic part field, concretely is a plastic part split structure. BACKGROUND
[0002] The electric tricycle can flexibly pass through the narrow road, is very convenient whether driving or parking, so it is widely used in the short distance transportation field such as family, town and country, individual rental, factory area, mining area, environmental sanitation, community cleaning, etc. At present, the electric tricycle is low in price, and the development investment is low, so the cooperation between the plastic parts is not tight, and the cooperation gap between the plastic parts is large, so a plastic part split structure is needed, which can reduce the flash gap problem between the plastic parts, improve the appearance performance of the whole vehicle, improve the product quality, facilitate operation, have high practicality and reduce product development investment cost.
[0003] Therefore, a plastic part split structure is provided. SUMMARY
[0004] The utility model discloses a plastic part split structure, solves the appearance performance of existing tricycle and has the problems such as the cooperation flash gap between the plastic parts is big, and the high-precision mould investment is big.
[0005] To achieve the above object, the utility model provides the following technical scheme:
[0006] A plastic part split structure, comprising an outer shell and an inner shell, the outer shell is injection molded with a stud on the inner side, and the inner shell is injection molded with a recess on the inner side.
[0007] The stud is tightly fastened with the recess.
[0008] The two sides of the outer shell are clamped with the inner shell.
[0009] Further, the two sides of the outer shell are injection molded with a convex plate.
[0010] Further, the inner shell is injection molded with a recess plate clamped with the convex plate.
[0011] Further, the outer shell is injection molded with a reinforcing rib.
[0012] Further, the inner shell is injection molded with a reinforcing rib.
[0013] Further, the convex plate and the recess plate are fastened by self-tapping.
[0014] Compared with the prior art, the utility model has the advantages that:
[0015] The stud of the outer shell is sunk in the recess of the inner shell, which can reduce the flash gap problem between the plastic parts, improve the appearance performance of the whole vehicle, improve the product quality, and facilitate operation.
[0016] When the shell stud is fastened with the inner shell recess, the convex plates on both sides of the shell sink into the concave plates of the inner shell, which can guarantee the flash problem between the plastic parts, has strong practicability, and reduces the investment cost of the high-precision mold of the product. BRIEF DESCRIPTION OF DRAWINGS
[0017] Fig. 1 It is a shell structure schematic view of the present application;
[0018] Fig. 2 It is an inner shell structure schematic view of the present application;
[0019] Fig. 3 It is an inner and outer shell cooperation profile schematic view of the present application. DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application.
[0021] Embodiment 1:
[0022] Please refer to Figs. 1-3 The present application provides a technical solution:
[0023] A split structure between plastic parts, comprising a shell 1 and an inner shell 6, the inner side of the shell 1 is injection molded with a reinforcing rib 3, two side convex plates 2 and a stud 4, the inner side of the inner shell 6 is injection molded with a reinforcing rib 3, two side concave plates 5 and a recess 7, the stud 4 is fastened and matched with the recess 7, and the two sides of the shell 1 are clamped with the inner shell 6 (the convex plates 2 are injection molded on both sides of the shell 1, the concave plates 5 which are clamped with the convex plates 2 are injection molded on the inner shell 6, so that the convex plates 2 and the concave plates 5 are fastened by self-tapping), which can reduce the flash problem between the plastic parts, improve the appearance performance of the whole vehicle, improve the product quality, facilitate operation, has strong practicability, and reduces the product development investment cost.
[0024] Working principle:
[0025] When the shell 1 is matched with the inner shell 6, the stud 4 is fastened and matched with the recess 7, thereby reducing the flash problem between the plastic parts, improving the appearance performance of the whole vehicle, improving the product quality, and facilitating operation.
[0026] When the stud 4 is fastened with the inner shell recess 7, the convex plates 2 on both sides of the shell 1 sink into the concave plates 5 of the inner shell 6, which can guarantee the flash problem between the plastic parts, has strong practicability, and reduces the investment cost of the high-precision mold of the product.
[0027] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
