Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automotive instrument panel covering, and specifically relates to a heating structure for the airbag frame area of an automotive instrument panel. Background Technique
[0002] Before the assembly of automotive interior parts (instrument panel), a series of process treatments will be carried out. The hot pressing and covering process is one of the important processes for automotive interior parts, aiming to enhance the overall luxury feeling, sound insulation and fire prevention of the automotive interior. Plastic parts such as automotive door panels are covered with a layer of leather after injection molding. Hot pressing and covering is a process of covering the plastic parts with leather after adding glue through external heating. This process mainly aims to integrate the leather and the plastic parts as a whole. However, there is an airbag frame on the instrument panel, and the airbag frame is originally welded to the instrument panel. Considering that welding the covered product may cause wear on the covered surface of the product, it is considered to weld the airbag frame to the instrument panel first and then carry out the covering. In this case, the airbag frame area cannot be heated evenly. Therefore, it is necessary to heat the airbag frame area. If only the traditional method of passing hot water is used for heating, a good heating effect cannot be achieved. The main reason is that the wall thickness of the airbag frame is too large and there are relief positions around it, resulting in poor covering when covering the airbag frame area.
[0003] The existing heating structures for the airbag frame area usually use the method of hot water heating to heat the airbag frame area of the instrument panel. This method cannot directly heat and can only heat through the heat around the mold cavity. The airbag frame is large and has strange shape characteristics. Relying solely on the surrounding temperature to heat simply cannot meet the temperature requirements for covering, resulting in phenomena such as unreliable covering and product bulging in the area where the airbag frame is covered. Summary of the Utility Model
[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a heating structure for the airbag frame area.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] A heating structure for the airbag frame area, characterized in that it includes a mold 1, an outer insert 2 for the airbag frame, an inner insert 3 for the airbag frame, a heater 4, a hot air duct 5 and an airbag frame 6; wherein: an airbag frame 6 is arranged on the mold 1, an inner insert 3 for the airbag frame is inlaid inside the airbag frame 6, an outer insert 2 for the airbag frame is inlaid outside the airbag frame 6, and two air blowing ports are arranged inside the outer insert 2 for the airbag frame; the heater 4 is connected to the hot air duct 5, and the hot air duct 5 penetrates through the two air blowing ports.
[0007] The utility model also has the following additional technical features:
[0008] As a further specific optimization of the technical solution of the present utility model: the outer side insert block 2 of the airbag frame is several raised aluminum blocks arranged on the outer side surface of the airbag frame 6.
[0009] As a further specific optimization of the technical solution of the present utility model: the inner side insert block 3 of the airbag frame is several raised aluminum blocks arranged on the inner side surface of the airbag frame 6.
[0010] As a further specific optimization of the technical solution of the present utility model: the model of the heater 4 is Leister LHS-21L-SYSTEM-139.910, 3.3KW.
[0011] As a further specific optimization of the technical solution of the present utility model: the hot air duct 5 is a pipeline connecting the heater 4 for transporting hot air.
[0012] As a further specific optimization of the technical solution of the present utility model: the airbag frame 6 is plastic on the interior trim of the car dashboard.
[0013] Compared with the prior art, the advantages of the present utility model are as follows:
[0014] The airbag frame area heating structure of the present utility model replaces the conventional hot water heating method and uses hot air heating in the area of the dashboard airbag frame 6. The advantage of using hot air is that it can directly blow hot air on the airbag frame 6 to heat the airbag frame 6. The airbag frame 6 is relatively large and has a strange shape. The airbag frame area heating structure can blow hot air into each groove of the airbag frame 6, so that the temperature in the area of the airbag frame 6 reaches the desired temperature, maximizing the effect on the wrapped product.
[0015] For the airbag frame area heating structure of the present utility model, the heater 4 transmits hot air to the outer side insert block 2 and the inner side insert block 3 of the airbag frame through the connected hot air duct, blows hot air on the airbag frame 6 to make the airbag frame 6 reach a specific temperature, which plays a very good role in the subsequent product wrapping.
