Description

Technical Field

[0001] This invention belongs to the field of automotive seat technology, specifically relating to a transparent decorative component for automotive seats and a backrest panel, as well as a method for manufacturing the transparent decorative component for automotive seats. Background Technology

[0002] Car seats are the seats used for seating in a car, and they are an important part of protecting drivers, passengers, and occupants. With rising living standards and changing consumer attitudes, consumers are placing higher demands on car seats, expecting them to be more aesthetically pleasing in addition to basic safety and comfort.

[0003] However, the decorative effect of car seat back panel trim strips on the market is generally poor. They are usually painted or electroplated, which is very monotonous and provides a poor experience. They are not aesthetically pleasing or comfortable enough, which is not conducive to improving the passenger experience.

[0004] Therefore, it is necessary to propose a new type of automotive seat trim. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide a transparent decorative component and backrest panel for automotive seats. The transparent outer shell of the decorative component showcases a mirror-like decorative layer, enhancing its aesthetics and perceived quality. The outer shell of the decorative component and the base of the decorative component are fixed using a combination of snap-fit ​​and adhesive bonding, achieving both integration and stability of the decorative component.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present invention provides a transparent decorative component for an automotive seat, comprising a decorative component housing, a decorative layer, and a decorative component base, wherein the decorative component housing is transparent, the decorative layer is located between the decorative component housing and the decorative component base, and the decorative component housing and the decorative component base are bonded and fixedly connected; wherein the decorative layer is a plating layer covering the inner surface of the decorative component housing.

[0008] This invention divides the decorative part into three parts. The decorative layer is protected by the outer shell of the decorative part. The transparent outer shell of the decorative part does not affect the appearance of the decorative layer. Compared with the existing technology of setting the decorative layer on the outer surface of the outer shell of the decorative part, this invention breaks through the existing flat texture decoration or single electroplating decoration of the decorative part. It uses the mirror reflection effect to obtain a transparent three-dimensional metallic texture of the decorative part, which increases the aesthetics and grade of the decorative part.

[0009] Preferably, the inner surface of the decorative component's outer shell is provided with a three-dimensional texture, and the inner surface of the decorative component's base matches the shape of the inner surface of the decorative component's outer shell. Since the decorative layer covers the inner surface of the decorative component, the three-dimensional texture of the decorative component's outer shell has a mirror-like three-dimensional reflective effect, resulting in a rich visual effect.

[0010] Preferably, the top surface of the decorative component housing is provided with a first snap-fit ​​groove, the bottom surface of the decorative component housing is provided with a second snap-fit ​​groove, the top surface of the decorative component base has a protruding first snap-fit ​​part that mates with the first snap-fit ​​groove, and the bottom surface of the decorative component base has a protruding second snap-fit ​​part that mates with the second snap-fit ​​groove. The decorative component housing and the decorative component base are snap-fitted together to assist in positioning. The fixed connection method between the decorative component housing and the decorative component base is adhesive bonding. However, before the adhesive has cured, the decorative component housing and the decorative component base are prone to displacement and misalignment. The connection method of the snap-fit ​​groove and the snap-fit ​​part facilitates the pre-installation and positioning of the decorative component housing and the decorative component base, effectively preventing misalignment during the adhesive bonding process.

[0011] Preferably, the bottom surface of the first snap-fit ​​groove is provided with multiple positioning grooves, and the bottom surface of the first snap-fit ​​part is provided with multiple positioning protrusions. When the first snap-fit ​​part is connected to the first snap-fit ​​groove, the positioning protrusions are snapped into the positioning grooves to play an auxiliary positioning role.

[0012] Preferably, a flow guide gap is provided between the second snap-fit ​​groove and the second snap-fit ​​portion. The function of the flow guide gap is to drain excess adhesive and avoid affecting the thickness of the decorative component assembly.

[0013] Preferably, the height of the flow guide gap is greater than or equal to 0.5 mm.

[0014] Preferably, the outer surface of the decorative component base is provided with multiple connecting posts to facilitate connection with the seat back panel.

[0015] Preferably, the outer shell of the decorative component has first mating edges with undulating shapes on both sides, and the base of the decorative component has second mating edges that match the first mating edges on both sides. After the outer shell of the decorative component contacts the base of the decorative component, the first mating edges and the second mating edges on the same side fit together to form a complete plane.

[0016] Preferably, the first mating edge has a mating groove on the side facing the base of the decorative part, and the second mating edge has a mating protrusion that mates with the mating groove on the side facing the outer shell of the decorative part, and the mating protrusion is embedded in the mating groove.

[0017] In a second aspect, the present invention provides a backrest panel including the aforementioned decorative element, wherein the decorative element is fixedly connected to the backrest panel of a car seat via a connecting post on the outer surface of the decorative element base.

[0018] In a third aspect, the present invention provides a method for manufacturing a transparent trim piece for automobile seats, comprising the following steps:

[0019] S1. Use injection molding to manufacture the decorative part base and the decorative part shell;

[0020] S2. Pre-assemble the decorative part shell and the decorative part base, ensuring that there is space between the decorative part shell and the decorative part base for applying adhesive;

[0021] S3. Separate the decorative part shell from the decorative part base, and plate a decorative layer on the inner surface of the decorative part shell;

[0022] S4. Apply adhesive to the outer surface of the decorative layer or the inner surface of the decorative base, reassemble the decorative shell and the decorative base, apply pressure to embed the decorative shell into the decorative base, and let the excess adhesive flow out from the guide gap.

[0023] S5. Clean up any adhesive that has flowed out of the drainage gaps. After the adhesive has solidified, the manufacturing of the transparent trim piece for the car seat is complete.

[0024] Beneficial effects:

[0025] This invention employs a connection method that relies primarily on adhesive bonding in addition to snap-fit, thus solving the problem of misalignment that may occur during the assembly of decorative parts. The outer shell of the decorative part and the base of the decorative part are fixed together by adhesive bonding, resulting in good integration and a stable connection.

[0026] This invention provides protection for the decorative layer by placing a decorative layer between the outer shell and the base of the decorative component. This prevents the decorative layer from being scratched or oxidized and aged. Since the outer shell of the decorative component is transparent, the plating layer (i.e., the decorative layer) can be displayed. Various three-dimensional textures can be set on the inner surface of the outer shell of the decorative component, giving the decorative component assembly a three-dimensional mirror effect and a metallic texture. It is aesthetically pleasing and has a high-end feel. Attached Figure Description

Detailed Implementation

[0032] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0033] This invention provides a transparent decorative component for car seats, comprising a decorative component housing 1, a decorative layer 4, and a decorative component base 2, as shown below. Figure 1 and 2 As shown, the decorative layer 4 is located between the decorative shell 1 and the decorative base 2. The decorative shell 1 is transparent and allows light to pass through, serving to display the decorative layer 4. The decorative shell 1 can be made of PC, PMMA, or crystal material. The decorative shell 1 serves to protect and display the decorative layer 4. The decorative shell 1 is fixedly connected to the decorative base 2 to form a whole.

[0034] In this invention, such as Figure 2 As shown in the view, the left side of the decorative component shell 1 is the outer surface of the decorative component shell 1, the right side of the decorative component shell 1 is the inner surface of the decorative component shell 1, the top of the decorative component shell 1 is the top surface of the decorative component shell 1, the bottom of the decorative component shell 1 is the bottom surface of the decorative component shell 1, and the other two sides are the left and right sides of the decorative component shell 1; the left side of the decorative component base 2 is the inner surface of the decorative component base 2, the right side of the decorative component base 2 is the outer surface of the decorative component base 2, the top of the decorative component base 2 is the top surface of the decorative component base 2, and the bottom of the decorative component base 2 is the bottom surface of the decorative component base 2.

[0035] The decorative layer 4 can take various forms. It can be an independent decorative element or a plating layer. It is easy to understand that when the decorative layer 4 is an independent decorative element, since the decorative effect is achieved through the decorative element shell 1, the decorative layer 4 cannot be connected to the decorative element shell 1, but can only be connected to the decorative element base 2. However, when the decorative layer 4 is a plating layer, the decorative layer 4 can only cover the inner surface of the decorative element shell 1, and the other side of the decorative layer 4 is connected to the decorative element base 2 by adhesive.

[0036] In this invention, the decorative layer 4 is preferably a plating layer, covering the inner surface of the decorative component housing 1. That is, the transparent decorative component housing 1 displays the glossy plating layer, giving the decorative component a mirror-like reflective and metallic appearance, providing drivers and passengers with a beautiful and high-end visual experience. The plating layer can be formed by electroplating, vacuum electroplating, vacuum sputtering, or painting.

[0037] In this invention, the structure of the inner surface of the decorative component housing 1 directly affects the display of the decorative layer 4. The inner surface structure of the decorative component housing 1 can be diverse, and various three-dimensional textures can be set to enhance the display effect of the decorative layer 4. The inner surface of the decorative component housing 1 can be set with geometric three-dimensional textures. After the inner surface is covered with a plating layer, the geometric three-dimensional textures are displayed under light, for example, as... Figure 1 As shown, the inner surface of the decorative part housing 1 is provided with multiple tetrahedral grooves, and the plating covering the inner surface of the decorative part housing 1 is displayed in a relatively three-dimensional form.

[0038] The connection between the decorative component housing 1 and the decorative component base 2 can be varied. For example, they can be fixed with screws, snap-fit, or adhesive. Considering the integrity and stability of the connection between the decorative component housing 1 and the decorative component base 2, it is preferable that the decorative component housing 1 and the decorative component base 2 are fixed with the assistance of a snap-fit ​​structure, and then fixed with adhesive to achieve integral fixation.

[0039] It should be noted that the inner surface of the decorative base 2 matches the inner surface of the decorative shell 1, facilitating a fixed connection using adhesive. For example, when the inner surface of the decorative shell 1 is provided with multiple tetrahedral grooves, the inner surface of the decorative base 2 is provided with multiple corresponding tetrahedral protrusions. It is easy to understand that a certain gap is still maintained between the decorative shell 1 and the decorative base 2 to facilitate the application of adhesive.

[0040] Specifically, such as Figure 1-4 As shown, the top surface of the decorative part shell 1 is provided with a first snap-fit ​​groove 5, and the bottom surface of the decorative part shell 1 is provided with a second snap-fit ​​groove 6. The top surface of the decorative part base 2 is provided with a first snap-fit ​​part 8 that cooperates with the first snap-fit ​​groove 5, and the bottom surface of the decorative part base 2 is provided with a second snap-fit ​​part 9 that cooperates with the second snap-fit ​​groove 6. The decorative part shell 1 and the decorative part base 2 are connected, and the decorative part shell 1 is located between the first snap-fit ​​part 8 and the second snap-fit ​​part 9. The combined state of the decorative part shell 1 and the decorative part base 2 is shown in the figure. The decorative part base 2 plays the role of surrounding the decorative part shell 1, and in the case of adhesive fixation, it prevents the decorative part shell 1 and the decorative part base 2 from being misaligned during installation.

[0041] Furthermore, such as Figure 1 , 3As shown in Figure 4, the bottom surface of the first latching groove 5 is provided with multiple positioning grooves 7, and correspondingly, the bottom surface of the first latching part 8 is provided with multiple positioning protrusions 10. When the first latching part 8 is connected to the first latching groove 5, the positioning protrusions 10 are engaged in the positioning grooves 7, playing an auxiliary positioning role. In this invention, the fitting connection between the positioning protrusions 10 and the positioning grooves 7 serves as a fixed fulcrum, combined with the attached... Figure 1 It can be seen that before the formal application of adhesive, the decorative part shell 1 and the decorative part base 2 can be pre-assembled and aligned by snap-fitting. The interlocking connection between the positioning protrusion 10 and the positioning groove 7 allows the decorative part shell 1 and the decorative part base 2 to be initially fixed. After confirming that the installation is correct, the bottom end of the decorative part base 2 can be pried outward to separate the two. After applying adhesive to the inner surface of the decorative part shell 1, the interlocking connection between the positioning protrusion 10 and the positioning groove 7 is used as a fixing point to apply pressure to the decorative part shell 1 to bond the decorative part shell 1 and the decorative part base 2.

[0042] The depth of the positioning groove 7 is greater than or equal to 0.5 mm, preferably ranging from 0.5 to 2.0 mm. Similarly, the height of the positioning protrusion 10 matches the depth of the positioning groove 7 and cannot exceed the depth of the positioning groove 7.

[0043] Furthermore, to improve the alignment between the decorative housing 1 and the decorative base 2, the decorative housing 1 has undulating first mating edges on both sides, and the decorative base 2 has second mating edges on both sides that match the first mating edges. After the decorative housing 1 and the decorative base 2 come into contact, the first and second mating edges on the same side interlock to form a complete plane. It is easy to understand that when the decorative housing 1 and the decorative base 2 are bonded, they are prone to sliding and misalignment before the adhesive has fully cured. The connection between the snap-fit ​​groove and the snap-fit ​​part prevents the decorative housing 1 and the decorative base 2 from misaligning in the vertical direction, while the mating of the first and second mating edges prevents the decorative housing 1 and the decorative base 2 from misaligning in the horizontal direction.

[0044] It should be noted that, Figure 3 This is a cross-sectional view showing the interior of the decorative component housing 1. Figure 4 This is a cross-sectional view showing the left and right sides of the decorative base 2. Figure 3 and Figure 4 It does not correspond.

[0045] Furthermore, a mating groove is provided on the side of the first mating edge facing the decorative base 2, and a mating protrusion that mates with the mating groove is provided on the side of the second mating edge facing the decorative shell 1. (Not shown in the attached figure) The mating protrusion is embedded in the mating groove, thereby achieving initial locking between the decorative shell 1 and the decorative base 2 in the left and right side directions.

[0046] Since the decorative base 2 has a wrapping effect on the decorative shell 1, in order to allow excess adhesive to be discharged without affecting the overall thickness of the decorative part, when the decorative shell 1 and the decorative base 2 are fixedly connected, a guide gap 11 is provided between the second snap-fit ​​groove 6 and the second snap-fit ​​part 9. The height of the guide gap 11 is greater than or equal to 0.5mm. Preferably, the height range of the guide gap 11 is 0.5 to 1.0mm.

[0047] Specifically, the location of the flow guide gap 11 is, attached to Figure 2 From a visual perspective, the gap between the top surface of the second snap-fit ​​part 9 and the outer shell 1 of the decorative part, and the gap between the left side surface of the second snap-fit ​​part 9 and the outer shell 1 of the decorative part, are connected to form a flow guide gap 11. When the outer shell 1 of the decorative part and the base 2 of the decorative part are attached, the adhesive between them is blocked from the top and left and right sides, and can only flow out along the flow guide gap 11, which facilitates subsequent processing. Moreover, the adhesive flows out at the bottom surface of the decorative part, which is relatively hidden and does not affect the aesthetics of the decorative part.

[0048] Multiple connecting posts 3 are provided on the outer surface of the decorative component base 2, and the decorative component assembly is fixedly connected to the seat back panel through the connecting posts 3.

[0049] Because the structure of the decorative component assembly of this invention differs from that of conventional decorative strips, this invention also proposes a method for manufacturing a transparent decorative component for automotive seats, the specific steps of which are as follows:

[0050] (1) The decorative base 2 and the decorative shell 1 are manufactured by injection molding;

[0051] (2) Pre-assemble the decorative part shell 1 and the decorative part base 2 to ensure that there is space for applying adhesive between the decorative part shell 1 and the decorative part base 2. Specifically, after pre-assembly, there is a flow guide gap 11 between the decorative part shell 1 and the decorative part base 2, indicating that there is space for applying adhesive between the decorative part shell 1 and the decorative part base 2. During subsequent bonding, excess adhesive can flow out along the flow guide gap 11. Otherwise, the decorative part shell 1 and the decorative part base 2 are deemed unqualified.

[0052] (3) Separate the decorative part shell 1 from the decorative part base 2, and plate the decorative layer 4 on the inner surface of the decorative part shell 1;

[0053] (4) Apply adhesive to the outer surface of the decorative layer 4 or the inner surface of the decorative base 2, reassemble the decorative shell 1 and the decorative base 2, apply pressure to make the decorative shell 1 as embedded as possible into the decorative base 2, ensure that the thickness of the decorative assembly meets the requirements, and allow excess adhesive to flow out from the guide gap 11.

[0054] (5) Clean the adhesive that has flowed out of the drainage gap 11. After the adhesive has solidified, the manufacturing of the decorative part assembly is completed.

[0055] Among them, decorative component assembly or decorative component refers to transparent decorative components for car seats.

[0056] Subsequently, the trim assembly is fixedly connected to the seat back panel via connecting column 3.

[0057] In the manufacturing method of the present invention, since positioning protrusions 10 and positioning grooves 7 are respectively designed on the top surfaces of the decorative component base 2 and the decorative component shell 1, pre-assembly can be performed. The pre-assembly step has an important impact on the product quality of the decorative component assembly. The positioning protrusions 10 are embedded in the positioning grooves 7, so that the decorative component base 2 and the decorative component shell 1 have a fixed connection fulcrum. By pushing the decorative component shell 1, it can be observed whether there is a gap between the decorative component shell 1 and the decorative component base 2, and it can be determined whether the guide gap 11 and the reserved space for applying adhesive exist.

[0058] During the bonding process, due to the presence of the first mating edge and the second mating edge, as well as the snap-fit ​​groove and the snap-fit ​​part, the decorative base 2 actually plays a role in wrapping the decorative shell 1, thus effectively preventing the two from sliding and misaligning.

[0059] It should be noted that the thickness of the decorative layer 4 is relatively small, less than the width of the gap between the decorative base 2 and the decorative shell 1 during pre-assembly. Therefore, even though the electroplating of the decorative layer 4 is performed after the pre-assembly step, it does not affect production. Furthermore, placing the electroplating step after pre-assembly also prevents scratches or other damage to the decorative layer 4 during the pre-assembly process.

[0060] The embodiments provided by the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention, and the descriptions of the embodiments above are only for the purpose of helping to understand the core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
