[0001] The utility model relates to the technical field of automobile storage bins, and particularly provides an automobile front storage device. Background Art

[0002] With the increasing global requirements for environmental protection and energy efficiency, the lightweighting of automobiles has become an important trend in the industry development and a trend in the world's automobile development. Automobile lightweighting means that, on the premise of ensuring the strength and safety performance of the automobile, the overall vehicle mass of the automobile is reduced as much as possible, so as to improve the power performance of the automobile, reduce fuel consumption, and reduce exhaust pollution. Experiments have proved that when the mass of an automobile is reduced by half, the fuel consumption will also be reduced by nearly half. The rapid rise of the new energy vehicle market and the increasing demand of traditional fuel vehicles for fuel economy and emission standards have jointly promoted the growing demand for automobile lightweighting.

[0003] New energy vehicles use a power motor instead of an engine, which makes the front engine compartment space of the vehicle larger. Many vehicle models use this space to design a front storage bin structure under the front engine compartment. With the rapid development of the automobile industry, the demand for automobile front storage bins is also increasing continuously. Especially with the rise of new energy vehicles, new requirements have been put forward for the design, materials, and processing of front storage bins. As Figure 1 and Figure 2 shown, the existing automobile front storage bins need to be manufactured by hot pressing and injection molding processes for the materials in sequence. The product itself has low load-bearing capacity, and it contains complex rib structures. Moreover, the installation points on the front storage bin cannot be directly obtained by hot pressing with the bin body at one time, and secondary injection molding processing needs to be carried out on the bin body. The long process time leads to low production efficiency and high cost. The installation points are not integrated with the front storage bin structure, resulting in a more complex overall structure of the storage bin. Summary of the Utility Model

[0024] In the following, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the same modules are denoted by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, their detailed descriptions will not be repeated.

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation to the present invention.

[0026] As Figure 3 shown, the present invention provides an automotive front storage bin device, including a storage bin body 1 and a mounting plate 2. The storage bin body 1 is a hexahedron structure with one side open and the other sides closed. In the embodiments of the present invention, the open surface of the storage bin body 1 is referred to as the bin opening 11, and the closed surface parallel to and corresponding to the bin opening 11 is the bin bottom 12. The bin opening 11 is an inlet for placing items into the automotive ABS front storage bin device.

[0027] The inner and outer surfaces of the storage bin body 1 are both smooth curved surfaces. Compared with traditional front storage bin devices, the automotive ABS front storage bin device in the embodiments of the present invention does not contain any "raised" structures such as stiffeners or "steps". Therefore, the automotive ABS front storage bin device in the embodiments of the present invention simplifies the traditional storage bin structure, saves some materials, and can save costs to a certain extent. Moreover, the inner surface of the automotive ABS front storage bin device is smooth, which is more convenient for placing items. At the same time, to ensure its strength, the wall thickness at any position of the automotive ABS front storage bin device is not less than 3 mm.

[0028] The mounting plate 2 and the storage bin body 1 are an integral structure. The bin opening 11 of the storage bin body 1 extends outward and folds to form the mounting plate 2 structure. The mounting plate 2 is an approximately quadrilateral annular structure. The inner edge of the mounting plate is connected to the opening edge of the storage bin, and it is arranged circumferentially along the outer edge of the bin opening 11 of the storage bin body 1. The outer edge shape of the mounting plate 2 is irregular and can be designed according to the installation position of the automotive ABS front storage bin device as required.

[0029] On the mounting plate 2, an annular sealing groove 3 is provided at the junction with the bin opening 11 of the storage bin body 1. The annular sealing groove 3 is approximately quadrilateral. Sealing members such as sealing rubber strips can be arranged in the annular sealing groove 3 to seal the automotive ABS front storage bin device and form an independent space for the user to store items.

[0030] The mounting plate 2 is also provided with a first stabilizing groove 4 and a second stabilizing groove 5. Both the first stabilizing groove 4 and the second stabilizing groove 5 are approximately crescent-shaped groove structures, which are respectively arranged on both sides of the storage bin body 1 and on the outer sides of the two short sides of the annular sealing groove 3. The first stabilizing groove 4 and the second stabilizing groove 5 are symmetrically arranged. When installing the automotive ABS front storage bin device through the mounting plate 2, since the first stabilizing groove 4 and the second stabilizing groove 5 are arranged in the plane areas on both sides of the mounting plate 2, the degree of bending deformation at the edge of the mounting plate 2 can be reduced, thereby increasing the strength of the mounting plate 2.

[0031] A plurality of mounting holes 6 are also distributed on the mounting plate 2. The diameter, shape, and position of the mounting holes 6 need to be set according to the installation position of the automotive ABS front storage bin device, and the automotive ABS front storage bin device can be installed at the working position through the mounting holes 6. Usually, the distribution of the mounting holes 6 on the mounting plate 2 is irregular and they are through-hole structures.

[0032] For the automotive ABS front storage bin device provided by the embodiment of the present utility model, the storage bin body 1, the mounting plate 2, and the annular sealing groove 3, the first stabilizing groove 4, the second stabilizing groove 5, and the mounting holes 6 on the mounting plate 2 are all structures obtained by integrally preparing through the thermoforming process. The embodiment of the present utility model uses ABS as the material and processes the automotive ABS front storage bin device by the thermoforming process. The ABS material is non-toxic and environmentally friendly, resistant to chemical corrosion, heat-resistant, not affected by humidity, and has a certain surface hardness, high elasticity, and toughness. It also has the processing and forming characteristics of thermoplastic plastics and improves the electrical properties, and has good impact resistance. Therefore, the ABS plastic is a "tough, hard, and rigid" material with easy availability of raw materials, good comprehensive performance, low price, stable performance, and wide application.

[0033] The thermoforming process is a thermoforming processing method. It uses thermoplastic plastic sheets to manufacture open plastic shell products through steps such as heating and softening, vacuum adsorption, and cooling and shaping. Specifically, after cutting the plastic sheet into a certain size, it is heated and softened, and by means of the air pressure difference and mechanical pressure on both sides of the sheet, it is deformed and then applied to a specific mold contour surface, and then through cooling and shaping, trimming the edges, and finally completing the thermoformed product.

[0034] Blister forming can only produce products with relatively uniform wall thickness. Generally, the wall thickness is slightly thinner at the chamfer, and plastic products with a large difference in wall thickness cannot be produced. When the material is heated and vacuum blistered, the material will first become soft, expand by blowing, and finally be vacuum adsorbed on the mold surface. The wall thickness of blister forming is generally within the range of 1 to 8 mm, or thinner or thicker. For example, the most commonly used thickness of the sheet for blister packaging of small packages is 0.15 to 0.25 mm. To ensure the uniform thickness of the product, ABS sheets are selected for the automotive ABS front storage bin device. It has a certain surface hardness, high elasticity and toughness. Therefore, ABS plastic is a material suitable for blister processing, and the thickness at the chamfer of the product can be well improved.

[0035] As Figure 4 shown, the specific preparation process of the automotive ABS front storage bin device of the embodiment of the present invention is as follows:

[0036] S1: According to the size of the automotive ABS front storage bin device, prepare the ABS raw material required for blistering. The ABS raw material can be sheet material or granular. In the embodiment of the present invention, the ABS sheet is taken as an example for illustration. The ABS sheet is pre-heat treated to ensure that the surface of the ABS sheet is clean and the ABS sheet becomes soft and has plasticity. The automotive ABS front storage bin device of the embodiment of the present invention is thick plate blistering. In order to make the automotive ABS front storage bin device stable, the wall thickness of the bin wall is not less than 2 mm. After forming, the depth of the storage bin body 1 is 310 mm. After the blister sheet is processed, the thickness of the automotive ABS front storage bin device becomes thinner relative to the sheet thickness. Therefore, the thickness of the ABS sheet should be set at about 2.5 mm, and the sheet size should ensure that it is at least 10 cm larger than the mold size.

[0037] S2: According to the shape and size of the automotive ABS front storage bin device, make the corresponding mold. The mold material needs to have sufficient strength and wear resistance to withstand the pressure and friction during the blistering process and be able to accurately replicate the shape of the product. The surface of the mold needs to be kept smooth and clean to avoid scratches or contamination on the surface of the automotive ABS front storage bin device. During use, the dust and oil on the surface of the mold need to be cleaned regularly, and the mold needs to be checked for damage or wear, and repaired or replaced in time.

[0038] S3: Place the pre-heated ABS sheet in the heating chamber of the blister machine for heating until the ABS sheet softens and has plasticity. Subsequently, place the softened ABS sheet on the mold and start the vacuum pump or use air pressure to make the raw material closely adhere to the mold surface to form the required automotive ABS front storage bin device. During the blistering process, the heating temperature and time are crucial for the forming quality of the product. In the embodiment of the present invention, according to the forming depth and sheet thickness of the automotive ABS front storage bin device, the heating time should be kept within 40 s.

[0039] S4: The formed automotive ABS front storage bin device needs to be sufficiently cooled and cured to ensure the stability of its shape and dimensions. Appropriate cooling methods and curing times need to be selected according to the characteristics of ABS and the requirements of the product. In the embodiment of the present utility model, according to the formed structure and material properties of the storage bin, the cooling time is maintained above 60 s.

[0040] S5: After cooling and curing, perform demolding operations and carry out necessary trimming on the obtained automotive ABS front storage bin device, such as trimming off excess corners or waste materials to make it more aesthetically pleasing and meet the design requirements.

[0041] S6: Conduct quality inspections on the finished automotive ABS front storage bin device products, and perform packaging after ensuring that they meet the quality standards.

[0042] The mounting hole 6 designed in the embodiment of the present utility model is a through-hole structure and can be directly obtained by thermoforming through the above method without the need to reprocess the mounting hole 6 on the molded automotive ABS front storage bin device body. The process is simplified and the efficiency is improved.

[0043] To ensure that the above-mentioned automotive ABS front storage bin device meets the usage requirements, the embodiment of the present utility model conducts performance verification tests on the automotive ABS front storage bin device, compares the performance data of the automotive ABS front storage bin device obtained by traditional fiber board compression molding injection with the performance data of the automotive ABS front storage bin device obtained by thermoforming in the embodiment of the present utility model, and obtains the data as shown in Table 1:

[0044] Table 1 Performance data of automotive ABS front storage bin device
