Description

Technical Field

[0001] This invention relates to the technical field of vehicle interiors, and more specifically, to an upper decorative panel for a door guard, a vehicle door, and a vehicle. Background Technology

[0002] Currently, the upper trim panels of automotive door panels mostly adopt an integral or simple splicing structure. Although the integral structure has a continuous appearance, the choice of materials and colors is limited, making it difficult to flexibly match according to the functional needs of different areas, and failing to balance practicality and decoration. The traditional splicing structure relies on clips or screws for direct connection, resulting in low connection strength, gaps and abnormal noises at the joints, poor positioning accuracy, and poor assembly flatness, which seriously affects the quality of the interior.

[0003] There is currently no good solution to the technical problem that the upper decorative panel of the automotive door panel cannot balance structural stability and styling flexibility in the existing technology. Summary of the Invention

[0004] The main objective of this invention is to provide an upper decorative panel for a door guard, a car door, and a vehicle, so as to solve the technical problem that the upper decorative panel of the existing car door guard cannot simultaneously achieve structural stability and styling flexibility.

[0005] To achieve the above objectives, according to one aspect of the present invention, an upper decorative panel for a door panel is provided, comprising: a panel body, wherein at least one groove is formed on the decorative surface of the panel body, the groove is disposed through the thickness direction of the panel body, and the groove divides the panel body into multiple component segments; and multiple panel skins, wherein the multiple panel skins are disposed in a one-to-one correspondence with the multiple component segments, each panel skin covering the decorative surface of the corresponding component segment, and the edge of the panel skin is bent and extends to the sidewall of the corresponding groove.

[0006] Furthermore, the trim panel body is provided with a first section and a second section distributed along the length direction of the door. The first section is connected to the second section through a connecting plate. The first section is provided with a first bend extending along the thickness direction of the door, and the second section is provided with a second bend extending along the thickness direction of the door. The connecting plate is provided between the first bend and the second bend, and the first bend, the second bend and the connecting plate surround to form a groove.

[0007] Furthermore, the connecting plate has a first bending structure.

[0008] Furthermore, the connecting plate includes at least: a first connecting segment, which is connected to a first bend and a second bend in the length direction of the trim body, the first connecting segment having a connecting segment A and a connecting segment B, the connecting segment A being connected to the connecting segment B, the connecting segment A extending along the thickness direction of the trim body, and the connecting segment B extending along the height direction of the trim body.

[0009] Furthermore, the connecting plate also includes: a second connecting segment, which is connected to the first bending portion and the second bending portion respectively in the length direction of the trim body. The second connecting segment is provided with connecting segment C and connecting segment D. Connecting segment C is connected to connecting segment D. Connecting segment C extends along the thickness direction of the trim body, and connecting segment D extends along the height direction of the trim body. Connecting segment C is connected to connecting segment B.

[0010] Furthermore, the connecting plate also includes: a third connecting segment, which is connected to the first bending portion and the second bending portion respectively in the length direction of the trim body. The third connecting segment is provided with connecting segment E and connecting segment F. Connecting segment E is connected to connecting segment F. Connecting segment E extends along the thickness direction of the trim body, and connecting segment F extends along the height direction of the trim body. Connecting segment E is connected to connecting segment D.

[0011] Furthermore, at least one of connecting segment A, connecting segment C, and connecting segment E is a second bending structure.

[0012] Furthermore, the second bending structure is set in a stepped shape along the length of the decorative panel body.

[0013] Furthermore, the upper decorative panel also includes a decorative cover plate, which is disposed between two adjacent component sections, and the decorative cover plate seals the groove and abuts the edge of the component section.

[0014] Furthermore, a first clearance structure is provided on the bottom wall of the groove, and part of the first pair of parts extends into the groove through the first clearance structure. The decorative cover plate is provided with a first connection structure that connects with the first pair of parts.

[0015] Furthermore, the decorative cover and the trim panel body enclose a cavity for installing the interior door handle, and the decorative cover is provided with a second connecting structure for connecting to the interior door handle.

[0050] In the automotive interior design field, door panels, as an important component, not only serve to protect the internal structure of the door and provide sound insulation and noise reduction, but their appearance and decorative effect also directly affect the overall quality and grade of the automotive interior. The upper trim panel, as a key decorative component of the door panel, is crucial to the assembly efficiency, stability, and aesthetics of the door panel itself.

[0051] In the existing technology, the upper decorative panel of automobile door panels mostly adopts an integral or simple splicing structure.

[0052] While the integrated decorative panel has the advantage of a strong overall appearance, it has the following drawbacks: the choice of materials and appearance colors is limited, and it is not possible to flexibly match different materials for the covering skin according to the functional needs of different areas (such as the front end needing to be wear-resistant, the middle section needing to be high-gloss, and the rear section needing to add personalized decorations such as stitching, etc.), making it difficult to balance practicality and decoration.

[0053] The simple splicing structure of the upper decorative panel usually connects the various segments directly with clips or screws, which has problems such as insufficient connection strength, gaps and abnormal noises at the splicing points, affecting the user experience. At the same time, the positioning accuracy of each segment is low, resulting in poor overall flatness after assembly, which reduces the appearance quality of the door panel.

[0054] To address the technical problem that existing decorative panels cannot simultaneously achieve structural stability and design flexibility, the following solution is provided.

[0055] Combination Figures 1 to 9 As shown, according to a specific embodiment of this application, an upper decorative panel for a door guard panel is provided.

[0056] Specifically, the upper decorative panel of the door guard panel includes: a decorative panel body 1 and multiple decorative panel skins. At least one groove 110 is formed on the decorative surface of the decorative panel body 1, the groove 110 is disposed through the thickness direction of the decorative panel body 1, and the groove 110 divides the decorative panel body 1 into multiple component segments. Multiple decorative panel skins are disposed in a one-to-one correspondence with multiple component segments, each decorative panel skin covering the decorative surface of the corresponding component segment, and the edges of the decorative panel skins are bent and extend to the sidewall of the corresponding groove 110.

[0057] In the embodiments of this application, the trim panel body 1 is a one-piece molded structure. The trim panel body 1 is divided into multiple segments by grooves 110 on the decorative surface. Each segment is a one-piece molded structure, requiring no additional connecting structures between segments, resulting in high connection strength and eliminating issues such as seams, poor positioning accuracy, and poor assembly flatness. Each segment can independently cover the trim panel surface, meaning each segment can be covered with trim panel surfaces of different colors and materials, achieving flexible styling of the upper decorative panel. In the above solution, the trim panel body 1, through its one-piece molding design and groove 110 structure, solves the technical problem in the prior art where the upper decorative panel of an automotive door panel cannot simultaneously achieve structural stability and styling flexibility.

[0058] In one exemplary embodiment of this application, such as Figure 1 As shown, the decorative panel body 1 is integrally molded using injection molding. A groove 110 is formed on the decorative surface of the decorative panel body 1. The groove 110 extends along the thickness direction of the decorative panel body 1 and divides the decorative panel body 1 into a first component segment 120 and a second component segment 130. The first component segment 120 and the second component segment 130 are distributed along the length direction of the decorative panel body 1, wherein the second component segment 130 has a U-shaped structure. The first component segment 120 is located near the first sidewall of the groove 110. A first decorative panel skin is covered on the decorative surface of the first component segment 120. The first decorative panel skin is bent at the first sidewall and covered to the surface of the first sidewall to perform edge finishing treatment on the first decorative panel skin. The second segment 130 is disposed near the second sidewall of the groove 110. The second sidewall of the groove 110 is disposed opposite to the first sidewall along the length direction of the trim panel body 1. The decorative surface of the second segment 130 is covered with a second trim panel skin. The second trim panel skin is bent at the second sidewall and covered to the surface of the second sidewall to perform edge finishing treatment on the second trim panel skin. The groove 110 formed on the decorative surface of the trim panel body 1 not only divides the trim panel body 1 into two segments, but also provides edge finishing space for the trim panel skin.

[0059] Furthermore, the trim panel body 1 is provided with a first component section 120 and a second component section 130 distributed along the length direction of the door. The first component section 120 is connected to the second component section 130 through a connecting plate 140. The first component section 120 is provided with a first bent portion 121 extending along the thickness direction of the door. The second component section 130 is provided with a second bent portion 131 extending along the thickness direction of the door. The connecting plate 140 is disposed between the first bent portion 121 and the second bent portion 131. The first bent portion 121, the second bent portion 131 and the connecting plate 140 surround each other to form a groove 110.

[0060] In the embodiments of this application, the first bending portion 121 and the second bending portion 131 both extend along the thickness direction of the door, effectively increasing the fitting depth and effective contact area between the edge of the trim panel skin and the trim panel body 1; the connecting plate 140 is disposed between the first bending portion 121 and the second bending portion 131. When the vehicle vibrates or experiences hot and cold cycles, the connecting plate 140 can evenly distribute the local stress to the trim panel body 1, avoiding stress concentration at the joint.

[0061] like Figure 1 , Figure 2 , Figure 3 As shown, the trim panel body 1 has a first component segment 120 and a second component segment 130. The first component segment 120 and the second component segment 130 are distributed along the length direction of the door (the length direction of the trim panel body 1). The first component segment 120 has a first bent portion 121 extending along the thickness direction of the door (the cross-sectional direction of the first component segment 120). The second component segment 130 has a second bent portion 131 extending along the thickness direction of the door (the cross-sectional direction of the second component segment 130). The first bent portion 121 is connected to the second bent portion 131 through a connecting plate 140. The connecting plate 140 extends along the length direction of the trim panel body 1. The first bent portion 121, the second bent portion 131 and the connecting plate 140 surround and form a groove 110.

[0062] The first segment 120 has a first decorative panel covering its decorative surface. The first decorative panel is bent at the first bend 121 and covers the surface of the first bend 121. The other edges of the first decorative panel are bent and cover the fixed surface of the first segment 120. The second segment 130 has a second decorative panel covering its decorative surface. The second decorative panel is bent at the second bend 131 and covers the surface of the second bend 131. The other edges of the second decorative panel are bent and cover the fixed surface of the second segment 130.

[0063] In another embodiment of this application, the connecting plate 140 is a first bending structure.

[0064] In the embodiments of this application, the connecting plate 140 is designed as a bent structure, which increases the moment of inertia of the section of the connecting plate 140. Compared with the flat plate structure, the bent connecting plate 140 has stronger bending and shear resistance in the direction perpendicular to the length of the door, effectively avoiding local yielding or fatigue cracking at the groove 110 of the trim panel body 1 due to sudden change in stiffness, and improving the overall strength of the trim panel body 1.

[0065] In another embodiment of this application, the connecting plate 140 includes at least: a first connecting segment 141, which is connected to a first bent portion 121 and a second bent portion 131 in the length direction of the decorative panel body 1. The first connecting segment 141 is provided with a connecting segment A1411 and a connecting segment B1412, which are connected to each other. The connecting segment A1411 extends along the thickness direction of the decorative panel body 1, and the connecting segment B1412 extends along the height direction of the decorative panel body 1.

[0066] In the embodiments of this application, the connecting segment A1411 extends along the thickness direction of the trim panel body 1, and the connecting segment B1412 extends along the height direction of the trim panel body 1, which increases the projected area of ​​the connecting plate 140 in the direction perpendicular to the length, that is, increases the overall width dimension of the connecting plate 140 and increases the overall cross-sectional moment of inertia of the connecting plate 140. Under vehicle driving vibration or external force impact, it can effectively resist multi-axial bending and torsional loads, avoid warping deformation and local yielding, and thus improve the overall strength of the trim panel body 1.

[0067] like Figure 2 , Figure 3 As shown, one end of the connecting plate 140 is connected to the first bent portion 121 of the first component segment 120, and the first bent portion 121 is perpendicular to the connecting plate 140. The other end of the connecting plate 140 is connected to the second bent portion 131 of the second component segment 130, and the second bent portion 131 is perpendicular to the connecting plate 140. The connecting plate 140, the first bent portion 121, and the second bent portion 131 form a groove 110. The connecting plate 140 includes a first connecting segment 141, which has an L-shaped structure. The first connecting segment 141 has a connecting segment A1411 and a connecting segment B1412. The connecting segment A1411 is connected to the connecting segment B1412. The connecting segment A1411 extends along the thickness direction of the decorative panel body 1, and the connecting segment B1412 extends along the height direction of the decorative panel body 1.

[0068] In another embodiment of this application, the connecting plate 140 further includes a second connecting segment 142, which is connected to the first bending portion 121 and the second bending portion 131 respectively in the length direction of the decorative panel body 1. The second connecting segment 142 is provided with a connecting segment C1421 and a connecting segment D1422. The connecting segment C1421 is connected to the connecting segment D1422. The connecting segment C1421 extends along the thickness direction of the decorative panel body 1, and the connecting segment D1422 extends along the height direction of the decorative panel body 1. The connecting segment C1421 is connected to the connecting segment B1412.

[0069] In the embodiments of this application, based on the first connecting segment 141, the connecting plate 140 further includes a second connecting segment 142. The connecting segment C1421 extends along the thickness direction of the decorative panel body 1, increasing the projection surface of the second connecting segment 142 in the direction perpendicular to the length, that is, increasing the overall width dimension of the connecting plate 140, further increasing the overall cross-sectional moment of inertia of the connecting plate 140, and further improving the overall strength of the decorative panel body 1.

[0070] like Figure 2 , Figure 3 As shown, the connecting plate 140 has a stepped structure and includes a first connecting segment 141 and a second connecting segment 142. The first connecting segment 141 and the second connecting segment 142 are distributed along the height direction of the decorative panel body 1, with the first connecting segment 141 located above the second connecting segment 142.

Connecting section C1421 and connecting section D1422 are connected. Connecting section C1421 extends along the thickness direction of the decorative panel body 1, and connecting section D1422 extends along the height direction of the decorative panel body 1. Connecting section C1421 is connected to connecting section B1412.

[0071] In another embodiment of this application, the connecting plate 140 further includes a third connecting segment 143, which is connected to the first bending portion 121 and the second bending portion 131 respectively in the length direction of the decorative panel body 1. The third connecting segment 143 is provided with a connecting segment E1431 and a connecting segment F1432. The connecting segment E1431 is connected to the connecting segment F1432. The connecting segment E1431 extends along the thickness direction of the decorative panel body 1, and the connecting segment F1432 extends along the height direction of the decorative panel body 1. The connecting segment E1431 is connected to the connecting segment D1422.

[0072] In the embodiments of this application, based on the first connecting segment 141 and the second connecting segment 142, the connecting plate 140 further includes a third connecting segment 143. The connecting segment E1431 extends along the thickness direction of the decorative panel body 1, increasing the projection surface of the third connecting segment 143 in the direction perpendicular to the length, that is, increasing the overall width dimension of the connecting plate 140, further increasing the overall cross-sectional moment of inertia of the connecting plate 140, and further improving the overall strength of the decorative panel body 1.

[0073] like Figure 2 , Figure 3 As shown, the connecting plate 140 has a stepped structure and includes a first connecting segment 141, a second connecting segment 142, and a third connecting segment 143. The first connecting segment 141, the second connecting segment 142, and the third connecting segment 143 are distributed along the height direction of the decorative panel body 1, and the second connecting segment 142 is located between the first connecting segment 141 and the third connecting segment 143. The first connecting segment 141 has an L-shaped structure and is provided with a connecting segment A1411 and a connecting segment B1412. The connecting segment A1411 is connected to the connecting segment B1412. The connecting segment A1411 extends along the thickness direction of the decorative panel body 1, and the connecting segment B1412 extends along the height direction of the decorative panel body 1. The second connecting segment 142 has an L-shaped structure and includes connecting segments C1421 and D1422. Connecting segment C1421 is connected to connecting segment D1422.

Connecting segment C1421 is connected to connecting segment B1412. The third connecting segment 143 has an L-shaped structure and includes connecting segments E1431 and F1432. Connecting segment E1431 is connected to connecting segment F1432. Connecting segment E1431 extends along the thickness direction of the trim panel body 1, and connecting segment F1432 extends along the height direction of the trim panel body 1. Connecting segment E1431 is connected to connecting segment D1422.

[0074] Furthermore, at least one of the connecting segments A1411, C1421, and E1431 is a second bending structure.

[0075] In the embodiments of this application, the connecting segment A1411, connecting segment C1421 or connecting segment E1431 is designed as a bent structure to further increase the overall strength of the connecting plate 140.

[0076] Furthermore, along the length of the decorative panel body 1, the second bending structure is arranged in a stepped shape.

[0077] like Figure 3As shown, the connecting segment E1431 has a stepped structure and includes: component segment A, component segment B and component segment C. Component segment A and component segment B extend along the length direction of the decorative panel body 1, and component segment C extends along the height direction of the decorative panel body 1. One end of component segment A is connected to the first bending part 121, and the other end of component segment A is connected to the bottom end of component segment B.

[0078] like Figure 3 , Figure 4 As shown, the bottom of the first component segment 120 is provided with a first flange, which extends along the thickness direction of the first component segment 120. The first flange is provided with a first extension 122, which extends along the length direction of the decorative panel body 1. The first extension 122 is connected to the bottom of the connecting segment F1432. The connecting segment F1432 is only connected to component segment A, that is, a clearance space is formed between component segment B, connecting segment F1432 and the second component segment 130. The first decorative panel skin covering the decorative surface of the first component segment 120 is bent at the edge of the connecting segment F1432 and then covered to the back of the connecting segment F1432 and the fixing surface of the first extension 122 through the clearance space, thereby finishing the edge of the first decorative panel skin.

[0079] In another embodiment of this application, the upper decorative panel further includes a decorative cover plate 2, which is disposed between two adjacent component sections, and the decorative cover plate 2 seals the groove 110 and abuts the edge of the component section.

[0080] In the implementation of this application, the decorative cover plate 2 can not only seal the groove 110 and block the joint between the components, but also increase the overall sense of layering of the upper decorative panel.

[0081] Furthermore, a first clearance structure 150 is provided on the bottom wall of the groove 110, and part of the first pair of parts 3 extends into the groove 110 through the first clearance structure 150. The decorative cover plate 2 is provided with a first connection structure 21 that connects to the first pair of parts 3.

[0082] In the embodiments of this application, the bottom wall of the groove 110 is a thin-walled part, and it is impossible to design a connection structure to connect with the decorative cover plate 2. The first pair of parts 3 extends into the groove 110 through the first clearance structure 150 and connects with the decorative cover plate 2, which not only provides a fixing point for the decorative cover plate 2, but also increases the connection strength between the first pair of parts 3 and the upper decorative plate.

[0083] like Figure 2 , Figure 8 , Figure 9As shown, the connecting plate 140, the first bent portion 121 of the first component segment 120, and the second bent portion 131 of the second component segment 130 form a groove 110, with the connecting plate 140 serving as the bottom wall of the groove 110. The connecting plate 140 has a stepped structure and includes a first connecting segment 141, a second connecting segment 142, and a third connecting segment 143. The first connecting segment 141, the second connecting segment 142, and the third connecting segment 143 are distributed along the height direction of the decorative panel body 1, with the second connecting segment 142 located between the first connecting segment 141 and the third connecting segment 143. The first connecting segment 141 has an L-shaped structure. The first connecting segment 141 is provided with connecting segment A1411 and connecting segment B1412. Connecting segment A1411 is connected to connecting segment B1412. Connecting segment A1411 extends along the thickness direction of the trim panel body 1, and connecting segment B1412 extends along the height direction of the trim panel body 1. A first clearance structure 150 is provided at the end of connecting segment A1411 away from connecting segment B1412. The first clearance structure 150 is formed in the notch of connecting segment A1411.
