Description

Prevent air vein glove box limit structure and car

Technical Field

The utility model relates to an automobile interior trim part, in particular to an anti-air-vein glove box limiting structure and an automobile.

Background

Along with the rapid development of the economy in China, automobiles gradually become an indispensable riding instead of walking tool in daily life of people, and meanwhile, the requirements of consumers on the automobiles are also higher. Glove boxes are one of the main functional components of instrument panel assemblies, and are mainly used for storing articles. The size, weight and storage position of the stored objects are related to the use habit and randomness of the user. Meanwhile, the external surface of the glove box and the moulding characteristics of the instrument board body are complex, and the glove box belongs to a moving part and is frequently opened and closed. Therefore, after a period of use, the gaps on the left side and the right side of the glove box are easy to cause uneven and even skew phenomena, and the appearance in the cab is further influenced. In order to change this phenomenon, a stopper structure is provided between the glove box and the instrument panel lower body. The limit structure is divided into a plurality of types, including cantilever beam clips, limit ribs, flanging and the like. Referring to fig. 1 to 5, the gap between the conventional glove box and the lower body of the instrument panel is generally limited by two first limiting ribs 3. The two first limit ribs 3 are formed by adopting an integral injection molding process, so that two concave small cavities are arranged at the positions corresponding to the limit ribs of the die. In the glue injection process, when the traditional glove box melt glue passes through the small cavity, air in the cavity is discharged outside the cavity after being impacted by the melt glue, and a piece of air vein is left at the root of the first limiting rib 3 in the traditional glove box. The air streak region is shown as region C in FIG. 4, and the appearance quality of the conventional glove box is seriously affected by the air streak. On the non-exterior surface, the air streak problem is usually solved by adding an air exhaust insert. However, the position of the air vein generated by the traditional glove box is the surface A of the product, if an air vent insert is added. Although the problem of air lines can be solved, the A surface of the traditional glove box is provided with an inlaid line, and the inlaid line leaks outside, so that the appearance quality of the glove box can be influenced.

Therefore, it is needed to find a limit structure of the anti-moire glove box, which not only can ensure a reliable limit function, but also can eliminate air lines, thereby meeting good appearance quality.

Disclosure of Invention

The utility model aims to provide an anti-moire glove box limiting structure and an automobile, and the anti-moire glove box limiting structure is improved, so that the injection defect of moire is eliminated, and the cost is reduced.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a prevent air vein glove box limit structure, includes the glove box body as an organic whole of moulding plastics, the both sides wall of glove box body is equipped with respectively with instrument board body complex spacing component, spacing component includes two piece at least spacing muscle and the communication structure between two spacing muscle, communication structure is connected between two spacing muscle, and the lateral wall inner bottom surface by the glove box body is gradually to the concave surface structure that spacing muscle direction of height was uplifted and is formed, communication structure can guide the gas that produces to flow to the spacing muscle direction of opposite side from the spacing muscle of one side through concave surface structure in the glove box body melt adhesive filling process to exhaust from the exhaust duct of mould.

According to the utility model, the communication structure with a special structure form is designed between the two limiting ribs, and the communication structure is a concave structure formed by gradually rising the inner bottom surface of the side wall of the glove box body towards the height direction of the limiting ribs. Thus, on the glove box injection mold, the two cavities corresponding to the two limit ribs are communicated through the communication structure. Namely, on the die, the position between the two corresponding limiting ribs is a relatively wide cambered surface, namely, the position corresponds to the concave surface of the communication structure. Therefore, the glove box body is filled with the melt adhesive, generated gas is not concentrated in two small cavities at the corresponding positions of the limiting ribs of the die, but flows to the limiting ribs at the other side from the concave surface of the limiting rib at one side through the concave surface of the communication structure, and is finally discharged through the exhaust grooves of the parting surface of the die, so that the air vein defect can not occur at the root of the limiting rib of the glove box body.

Further, the height of the bulge of the communication structure is not more than the height H of the limit rib. Preferably, the height of the bulge of the communication structure is greater than two thirds of the height H of the limit rib. Under the condition of increasing the above communication structural design, the limiting function of the limiting component can be ensured, and the reasonable limiting gap between the glove box body and the instrument board body can be ensured.

Further, the width of the communicating structure does not exceed the width L of the limiting rib, so that the limiting function of the limiting member is further guaranteed.

Further, the communication structure and the glove box body are integrally formed.

The utility model also provides an automobile, which comprises the anti-air-vein glove box limiting structure.

The utility model has the following advantages:

because the concave surface structure is formed on the bottom surface of the side wall of the glove box body towards the height direction of the limiting ribs, the two limiting ribs are connected through the concave surface structure, namely the communication structure. In the process of the glove box body melt adhesive, generated gas can flow from one side of the limiting rib to the other side of the limiting rib through the concave surface of the communication structure, and finally is discharged through the exhaust groove of the parting surface of the die, so that the gas cannot be concentrated at the root of the limiting rib. Therefore, the problems of long glove box modification time and high die repair cost caused by the air streak problem can be reduced.

In summary, by designing the communication structure 22 of a special structure between the two stopper ribs 21, the communication structure 22 is a concave structure formed by gradually bulging the inner bottom surface of the side wall of the glove box body 1 in the height direction of the stopper ribs. Thus, on the glove box injection mold, the two cavities corresponding to the two limiting ribs 21 are communicated through the communication structure. Namely, on the mold, the position between the two corresponding limiting ribs 21 is a relatively wide cambered surface, namely, the position corresponds to the concave surface of the communication structure, so that the generated gas in the filling process of the melt adhesive in the glove box body 1 can not be concentrated in two small cavities at the corresponding positions of the limiting ribs 21 of the mold, but flows to the limiting ribs 21 at the other side from the cambered surface of the mold through the concave surface of the communication structure 22 corresponding to the limiting rib 21 at one side, and is finally discharged through the exhaust groove of the parting surface of the mold. So that no air streak defect occurs at the root of the limit rib 22 of the glove box body 1. Therefore, the air line defect is eliminated, the appearance quality of the glove box is guaranteed, the glove box modifying time is saved, and the die repairing cost of the glove box is reduced.
