Description

Technical Field

[0001] The present disclosure relates to the technical field of automotive interiors, and particularly to a vehicle interior structure and a vehicle. Background Art

[0002] With the widespread popularity of automobiles, people's requirements for the comfort, luxury, and appearance quality of automotive interiors have gradually increased. The wrapping process is usually used to wrap the wrapping parts on the outside of the interior parts to improve the appearance quality and feel of the interior parts. The flatness of the wrapping parts on the interior parts affects the aesthetics of the automotive interior and also affects the feel when users touch the automotive interior.

[0003] The wrapping parts usually include an epidermis layer and a support layer. The support layer is a sponge structure. Glue is used to bond the support layer to the interior part. When the wrapping part is bonded to the interior part, it is necessary to press the wrapping part forcefully to make the wrapping part fit flat on the surface of the interior part. However, pressing the wrapping part forcefully easily causes the glue to penetrate into the support layer, resulting in uneven distribution of the glue between the wrapping part and the interior part, leading to wrinkles and protrusions on the surface of the wrapping part on the interior part; and when the force applied to the wrapping part is transmitted to the interior part, the interior part is easily deformed and sunken. After the wrapping part is bonded, the deformed part of the interior part returns, which will cause wrinkles and protrusions on the wrapping part on the interior part, affecting the flatness of the wrapping part on the automotive interior.

[0026] In order to more clearly understand the above objects, features and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0028] Referring to Figures 1 to 3 As shown, the vehicle interior structure provided by the embodiment of the present disclosure includes an interior skeleton member 1 and a covering member 2; the covering member 2 includes a skin layer 21, a support layer 22 and a water-repellent layer 23, and the skin layer 21, the support layer 22 and the water-repellent layer 23 are sequentially connected by flame lamination, and the skin layer 21 and the water-repellent layer 23 are respectively adhesively connected to both sides of the support layer 22; a glue layer 3 is provided on the side of the water-repellent layer 23 facing away from the support layer 22, and the thickness of each position of the glue layer 3 is equal, and the glue layer 3 is adhesively connected to the outer side of the interior skeleton member 1 so that the covering member 2 is attached to the outer side of the interior skeleton member 1, and the thickness of the interior skeleton member 1 is greater than or equal to a set thickness.

[0029] Specifically, the interior trim skeleton member 1 can be selected as the frame structure of the vehicle interior. For example, any one of the trunk trim panel skeleton, the middle trim panel skeleton of the door panel, the instrument panel body skeleton, the lower left guard plate skeleton, and the glove box cover plate skeleton can be the interior trim skeleton member 1. Of course, it is also possible to select that the trunk trim panel skeleton, the middle trim panel skeleton of the door panel, the instrument panel body skeleton, the lower left guard plate skeleton, and the glove box cover plate skeleton are all interior trim skeleton members 1, that is, the covering member 2 is adhesively connected to the front sides of the trunk trim panel skeleton, the middle trim panel skeleton of the door panel, the instrument panel body skeleton, the lower left guard plate skeleton, and the glove box cover plate skeleton. The covering member 2 wraps around the front side of the interior trim skeleton member 1, covering the surface of the interior trim skeleton member 1 with the covering member 2, protecting the interior trim skeleton member 1, and when the user uses the vehicle, the user observes and touches the skin layer 21 of the covering member 2, improving the aesthetics and feel of the vehicle interior.

[0030] The above-mentioned skin layer 21 can be selected to use artificial leather, synthetic leather or leather, so that the skin layer 21 has good stain resistance and a good feel.

[0031] The above-mentioned support layer 22 can be selected to be made of polyurethane or polymer. When the support layer 22 is heated by flame, the surface of the support layer 22 will melt, and the skin layer 21 and the water-repellent layer 23 will adhere to the melted surfaces on both sides of the support layer 22. When the support layer 22 cools down, the skin layer 21 and the water-repellent layer 23 can be adhesively connected to both side surfaces of the support layer 22.

[0032] The above-mentioned water-repellent layer 23 can be selected as non-woven fabric. The non-woven fabric adopts a water-repellent weaving method, so that liquid cannot pass through the gaps of the non-woven fabric, and thus glue cannot penetrate through the water-repellent layer 23 and enter the support layer 22.

[0033] The above-mentioned glue layer 3 can be formed by spraying glue on the water-repellent layer 23, or of course, it can also be formed by brushing glue on the water-repellent layer 23. The distances between the positions on the side of the glue layer 3 facing away from the water-repellent layer 23 and the water-repellent layer 23 are all equal, that is, the thicknesses of all positions of the glue layer 3 are the same.

[0034] One side of the above-mentioned interior trim skeleton member 1 exposed inside the vehicle is the front side of the interior trim skeleton member 1. The inner side and the front side of the interior trim skeleton member 1 are two opposite sides of the interior trim skeleton member 1. The distance between the front side and the inner side of the interior trim skeleton member 1 is the thickness of the interior trim skeleton member 1. The thickness of each position of the interior trim skeleton member 1 can be selected to be equal. Of course, the thickness of each position of the interior trim skeleton member 1 can also be selected to be uneven; the minimum thickness of the interior trim skeleton member 1 can be selected to be equal to the set thickness. Of course, the minimum thickness of the interior trim skeleton member 1 can also be selected to be greater than the set thickness; the set thickness can be selected to be 2.5 millimeters. The interior trim skeleton member 1 is a plastic part or a metal part. The thickness of the interior trim skeleton member 1 being greater than the set thickness can enable the interior trim skeleton member 1 to have a certain structural strength, so as to reduce the degree of deformation of the interior trim skeleton member 1 caused by the pressing force of the covering member 2 when pressing the covering member 2. After the covering member 2 is attached to the interior trim skeleton member 1, the deformation recovery of the interior trim skeleton member 1 will not cause the covering member 2 to form protrusions and wrinkles.

[0035] When the vehicle interior structure provided by the embodiment of the present disclosure is specifically used, the skin layer 21, the support layer 22, and the water-repellent layer 23 are connected to each other by flame lamination. Glue is sprayed on one side of the water-repellent layer 23 facing away from the support layer 22, so as to form a glue layer 3 on the water-repellent layer 23; the covering member 2 is covered on the front side of the interior trim skeleton member 1, and the water-repellent layer 23 is arranged opposite to the front side of the interior trim skeleton member 1. A force is applied to the skin layer 21 in the direction of the interior trim skeleton member 1, so that the glue layer 3 is closely attached to and bonded to the front side of the interior trim skeleton member 1. The force application point on the skin layer 21 is moved, and finally all of the water-repellent layer 23 is bonded to the front side of the interior trim skeleton member 1 through the glue layer 3, completing the covering of the interior trim skeleton member 1 by the covering member 2.

[0036] The vehicle interior structure provided by the embodiments of the present disclosure includes an interior skeleton member 1 and a covering member 2; the covering member 2 includes an epidermis layer 21, a support layer 22, and a water-repellent layer 23, and the epidermis layer 21, the support layer 22, and the water-repellent layer 23 are sequentially connected by flame lamination. The epidermis layer 21 and the water-repellent layer 23 are respectively adhered and connected to both sides of the support layer 22; a glue layer 3 is provided on the side of the water-repellent layer 23 facing away from the support layer 22, and the thickness of each position of the glue layer 3 is equal, so that the glue layer is evenly distributed on the water-repellent layer, avoiding local accumulation of the glue layer on the water-repellent layer and causing protrusions of the covering member on the interior skeleton member; the glue layer 3 is bonded to the outer side of the interior skeleton member 1, so that the covering member 2 is attached to the outer side of the interior skeleton member 1; the water-repellent layer 23 can prevent liquids from passing through, thereby avoiding the glue in the glue layer 3 from passing through the water-repellent layer 23 and entering the support layer 22 when the covering member 2 is pressed onto the interior skeleton member 1; the thickness of the interior skeleton member 1 is greater than or equal to a set thickness, so that the interior skeleton member has high structural strength, reducing the degree of deformation of the interior skeleton member 1 caused by the pressing force of the covering member 2, and avoiding the formation of protrusions and wrinkles on the covering member 2 due to the deformation recovery of the interior skeleton member 1. Through the mutual cooperation of the covering member 2 with the water-repellent layer 23 and the interior skeleton member 1, the flatness of the covering member 2 on the outer side of the interior skeleton member 1 is improved, so that the vehicle interior structure meets the user's requirements for appearance and feel.

[0037] Referring to Figure 1 and Figure 3 As shown, in some embodiments, the interior skeleton member 1 includes at least one of a trunk trim panel skeleton, a door trim panel middle skeleton, an instrument panel body skeleton, a guard plate skeleton, and a glove box cover plate skeleton. By setting it like this, the interior skeleton member 1 is applicable to various interiors of the vehicle, so that the covering member 2 can be wrapped on different interiors of the vehicle at different positions, improving the overall feel and aesthetics of the vehicle interior.

[0038] Specifically, the interior skeleton member 1 can be selected as the main frame of the trunk trim panel of the vehicle. Of course, it can also be selected as the main frame of the door trim panel middle, or the frame structure of the instrument panel body, or the frame structure of the guard plate of the vehicle. The guard plate can be selected as the engine guard plate of the vehicle, or it is not limited to the interior skeleton member 1 being the main frame of the glove box cover plate.

[0039] Referring to Figure 1 and Figure 3 As shown, in some embodiments, the water-repellent layer 23 includes non-woven fabric, and the water absorption grade of the non-woven fabric is greater than grade three. By setting it like this, the non-woven fabric is easy to adhere to glue, facilitating the adhesion of glue to the non-woven fabric to form a stable glue layer 3, and the water absorption grade of the non-woven fabric being greater than grade three ensures that the glue cannot penetrate the non-woven fabric and enter the support layer 22.

[0040] Specifically, the non-woven fabric can be selected as a water-repellent woven non-woven fabric. Of course, it can also be selected as a waterproof spunlace non-woven fabric, or it can also be selected as a waterproof low-tear knitted fabric, as long as the water contact grade of the non-woven fabric is greater than level three.

[0041] The above water contact grade is determined by GB / T 4745-2012 "Testing and Evaluation of Water Resistance of Textiles - Water Contact Method" to determine the water contact grade of the fabric and evaluate the water resistance of the fabric accordingly. The test method is to install the specimen on a circular holder, keep the holder at 45° to the horizontal, and the center position of the specimen is at a certain distance below the nozzle. Spray a certain amount of distilled water or deionized water on the specimen. After spraying, determine the water contact grade of the fabric by comparing the appearance of the specimen with the description and pictures of the water contact phenomenon, and evaluate the water resistance of the fabric accordingly.

[0042] The scoring standard for the water resistance of the measured fabric is divided into grades 0 to 5 according to the water contact grade, with grade 5 being the best; the water resistance evaluation of the water contact grade of 0 is that it does not have the performance of resisting wetting; the water resistance evaluation of the water contact grade of 1 to 2 is that the performance of resisting wetting is poor; the water resistance evaluation of the water contact grade of 2 to 3 is that the performance of resisting wetting is relatively poor; the water resistance evaluation of the water contact grade of 3 is that it has the performance of resisting wetting; the water resistance evaluation of the water contact grade of 3 to 4 is that it has good performance of resisting wetting; the water resistance evaluation of the water contact grade of 4 is that it has very good performance of resisting wetting; the water resistance evaluation of the water contact grade of 4 to 5 is that it has excellent performance of resisting wetting.

[0043] Refer to Figure 1 and Figure 3 As shown, in some embodiments, the support layer 22 includes foamed sponge, and the thickness of the foamed sponge at each position of the water-repellent layer 23 is equal. With this setting, the foamed sponge can support the water-repellent layer 23 and the skin layer 21, and the foamed sponge is easy to deform, so that the foamed sponge can deform to adapt to the shape of the outer side of the interior trim member 1, facilitating the fitting of the covering member 2 on the outer side of the interior trim member 1.

[0044] Specifically, the foamed sponge can be selected as a polyurethane PUR foamed sponge. Polyurethane PUR is a polymer with a repeating structural unit of urethane chain segments made by the reaction of isocyanate and polyol. PUR products are divided into two major categories: foamed products and non-foamed products. Foamed products include soft, hard, and semi-hard PUR foam plastics. PUR has excellent plasticity and strong practicality of material properties. The PUR foamed sponge itself has a certain structural strength and is easy to deform, enabling the PUR foamed sponge to not only support the water-repellent layer 23 and the skin layer 21, but also deform during the process of the covering member 2 fitting on the outer side of the interior trim member 1 to adapt to the shape of the interior trim member 1, so that the covering member 2 can fit on the interior trim member 1.

[0045] Refer to Figure 1 andFigure 2 As shown, in some embodiments, reinforcing ribs 11 are provided on the inner side of the interior trim skeleton member 1. With such an arrangement, the reinforcing ribs 11 can enhance the structural strength of the interior trim skeleton member 1 and improve the shape stability of the interior trim skeleton member 1. When the covering member 2 is attached to the outer side of the interior trim skeleton member 1, it can prevent the interior trim skeleton member 1 from deforming and affecting the flatness of the covering member 2 on the outer side of the interior trim skeleton member 1.

[0046] Specifically, the reinforcing ribs 11 can be selected as plate structures formed on the inner side of the interior trim skeleton member 1. The plate structures can be selected to extend in one direction, and there are multiple mutually parallel and spaced plate structures on the inner side of the interior trim skeleton member 1 as the reinforcing ribs 11. Of course, the reinforcing ribs 11 can also be selected as multiple plate structures formed on the inner side of the interior trim skeleton member 1, and the multiple plate structures intersect with each other to form a mesh structure.

[0047] Refer to Figure 1 and Figure 2 As shown, in some embodiments, the reinforcing ribs 11 include multiple first rib plates 111 and multiple second rib plates 112. The first rib plates 111 are arranged along a first direction, and the second rib plates 112 are arranged along a second direction. The multiple first rib plates 111 and the multiple second rib plates 112 are connected to each other to form a grid structure. There is an included angle with a set angle between the first direction and the second direction. With such an arrangement, the grid structure formed by the first rib plates 111 and the second rib plates 112 has a good strengthening effect on the interior trim skeleton member 1 in all directions, improving the overall structural strength of the interior trim skeleton member 1.

[0048] Specifically, the first rib plates 111 and the second rib plates 112 can be selected as straight plate structures. Of course, some of the first rib plates 111 or some of the second rib plates 112 can be selected as arc-shaped plates. The included angle between the first direction and the second direction can be selected as 90°. Of course, the included angle between the first rib plates 111 and the second rib plates 112 can also be selected as 30°, 45° or 60°, as long as the multiple first rib plates 111 and the multiple second rib plates 112 can be connected to each other to form a grid structure.

[0049] Refer to Figure 1 and Figure 2 As shown, in some embodiments, the set thickness is 2.5 millimeters. With such an arrangement, due to the limited space inside the vehicle, the thickness of the interior trim skeleton member 1 needs to be as small as possible. The set thickness of 2.5 millimeters ensures that the interior trim skeleton member 1 has sufficient structural strength while occupying a small space inside the vehicle, enabling the interior trim skeleton member 1 to only undergo a small amount of deformation when bearing the force transmitted by the covering member 2.

[0050] Specifically, the set thickness of 2.5 millimeters means that the minimum distance between the outer side and the inner side of the interior trim skeleton member 1 is greater than or equal to 2.5 millimeters, ensuring that the interior trim skeleton member 1 has sufficient structural strength.

[0051] Referring to Figure 1 and Figure 2 as shown, in some embodiments, the water-repellent layer 23 is sprayed with an adhesive amount of 100-140 g / m 2 to form an adhesive layer 3 with a thickness dimension of 0.1-0.15 mm at an adhesive spraying amount of 100-140 g / m, an adhesive spraying pressure of 0.4-0.6 MPa, and an adhesive spraying angle of 30-60°. With such a setting, a stable-thickness adhesive layer 3 can be formed on the water-repellent layer 23, enabling the covering member 2 to be smoothly bonded to the interior trim skeleton member 1 through the adhesive layer 3.

[0052] Specifically, the adhesive spraying process is to spray the adhesive on the surface of the article using a nozzle. When spraying the adhesive on the water-repellent layer 23, an adhesive spraying amount of 100-140 g / m2 is used. When the adhesive spraying amount is less than 100 g / m2, the time required to form an adhesive layer 3 with a sufficient thickness on the water-repellent layer 23 is relatively long, and it is easy for the adhesive to dry out; when the adhesive spraying amount is greater than 140 g / m2, it is difficult to control the adhesive spraying amount on the water-repellent layer 23, and it is easy for the thickness of the adhesive layer 3 formed locally on the water-repellent layer 23 to be relatively large, affecting the uniformity of the adhesive layer 3.

[0053] The above-mentioned adhesive spraying pressure is the pressure at which the adhesive is ejected from the nozzle. When the adhesive spraying pressure is between 0.4-0.6 MPa, the adhesive can be quickly bonded to the water-repellent layer 23. When the adhesive spraying pressure is less than 0.4 MPa, the bonding speed between the ejected adhesive and the water-repellent layer 23 is relatively slow. When the adhesive spraying pressure is greater than 0.6 MPa, the ejected adhesive is likely to flow on the water-repellent layer 23, making the thickness of the adhesive layer 3 formed by the ejected adhesive uneven.

[0054] The above-mentioned adhesive forms a plane after being ejected from the nozzle. The angle between the plane formed by the adhesive and the water-repellent layer 23 of the covering member 2 is between 30° and 60°, which is convenient for the adhesive to adhere to the water-repellent layer 23 and can prevent the adhesive from splashing around when it contacts the water-repellent layer 23. When the adhesive spraying angle is less than 30°, the contact angle between the adhesive and the water-repellent layer 23 is relatively small and it is not easy to bond to each other. When the adhesive spraying angle is greater than 60°, the adhesive is likely to splash around when it contacts the water-repellent layer 23, affecting the uniformity of the adhesive layer 3.

[0055] The thickness of the above-mentioned adhesive layer 3 is 0.1 to 0.15 mm. When the adhesive layer 3 is less than 0.1 mm, the adhesive force is relatively weak, affecting the stability of the mutual bonding between the covering member 2 and the interior trim skeleton member 1. When the adhesive layer 3 is greater than 0.15 mm, the adhesive layer 3 is relatively thick, making the distance between the water-repellent layer 23 and the surface side of the interior trim skeleton member 1 relatively far, affecting the fitting degree between the covering member 2 and the interior trim skeleton member 1.

[0056] Referring to Figure 1 and Figure 2As shown, in some embodiments, the flexural modulus of the interior trim skeleton member 1 is between 2000 - 2600 MPa. With this setting, the degree of deformation of the interior trim skeleton member 1 when subjected to an external force is small, avoiding the deformation of the interior trim skeleton member 1 from affecting the flatness of the covering member 2 on the surface side of the interior trim skeleton member 1.

[0057] Specifically, the flexural modulus of the interior trim skeleton member 1 is also known as the flexural modulus. It refers to the ratio of the flexural stress to the strain generated by bending, that is, the flexural modulus is the ratio of the flexural stress to the deformation generated by bending. The flexural modulus of the interior trim skeleton member 1 is between 2000 - 2600 MPa, so that the degree of deformation of the interior trim skeleton member 1 when subjected to an external force is small and will not affect the flatness of the covering member 2. If the flexural modulus of the interior trim skeleton member 1 is less than 2000 MPa, the degree of deformation of the interior trim skeleton member 1 when subjected to an external force is large. After the covering member 2 is bonded to the interior trim skeleton member 1, when the interior trim skeleton member 1 deforms and recovers, it is easy to cause the covering member 2 to form protrusions and wrinkles. If the flexural modulus of the interior trim skeleton member 1 is greater than 2600 MPa, it has relatively high requirements for materials and processing technologies, which will increase the manufacturing cost of the interior trim skeleton member 1.

[0058] The embodiment of the present disclosure also provides a vehicle, including the vehicle interior structure as described above.

[0059] Specifically, when the vehicle interior structure as described above is used on the vehicle, the covering member 2 is flatly and adhesively attached to the surface side of the interior trim skeleton member 1, improving the aesthetics of the vehicle interior. And when the user touches the surface of the vehicle interior structure, it is flat and has a good feel, meeting the user's requirements for the aesthetics and feel of the vehicle interior.

[0060] When the vehicle and the vehicle interior structure provided by the embodiment of the present disclosure are specifically used, the skin layer 21, the support layer 22, and the water-repellent layer 23 are connected to each other by flame lamination. On the water-repellent layer 23, a glue layer 3 with a thickness dimension of 0.1 - 0.15 mm is sprayed with a glue spraying amount of 100 - 140 g / m 2 , a glue spraying pressure of 0.4 - 0.6 MPa, and a glue spraying angle of 30 - 60°; the covering member 2 is covered on the surface side of the interior trim skeleton member 1, and the water-repellent layer 23 is disposed opposite to the surface side of the interior trim skeleton member 1. An acting force is applied to the skin layer 21 in the direction towards the interior trim skeleton member 1, so that the glue layer 3 is closely attached to and adhesively bonded to the surface side of the interior trim skeleton member 1. The acting point on the skin layer 21 is moved, and finally the entire water-repellent layer 23 is adhesively bonded to the surface side of the interior trim skeleton member 1 through the glue layer 3, completing the covering of the interior trim skeleton member 1 by the covering member 2; the vehicle interior structure is installed in the vehicle.

[0061] It should be noted that, in this document, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.
