1 / 6 DEVICE FOR FIXING A VEHICLE DOOR PANEL AND VEHICLE Field of the Invention

[0001] The present invention is situated in the field of systems and components for fastening automotive panels, more specifically in the development of an angled fastening for the lower region of the door panel. Background of the Invention

[0002] Vehicle door panels are fundamental elements in the design and functionality of automotive interiors. Beyond their structural function, which includes protecting and isolating occupants, these panels play a significant role in the aesthetic composition of the vehicle's interior, directly influencing the user's perception of quality and comfort. To meet these requirements, door panels must incorporate robust and discreet fasteners that efficiently connect the panel to the door structure, ensuring stability during use.

[0003] Conventional fastening solutions for the lower part of the door panel often present technical and aesthetic challenges. These fasteners, usually positioned in visible areas, necessitate covers or sleeves to conceal the holes, compromising the clean surface design and increasing production costs. The use of these covers can also negatively affect the perceived quality of the product, especially in higher-end vehicles.

[0004] Another problem with traditional fasteners is the limited usable space on the lower panel. The need to accommodate fastening points in already restricted areas can reduce the space available for additional features, such as storage pockets, USB connectors, ambient lighting, or custom design elements. These limitations affect the end-user experience, who seeks greater practicality and aesthetics in automotive interiors.

[0005] Although simple and low-cost solutions for lower door panel mounting exist on the market, they often fail to meet the demands of advanced design and perceived quality, especially in vehicles that prioritize visual and functional appeal. Therefore, there is a demand for innovations capable of offering more efficient mountings that combine high structural performance with improvements in space and aesthetic finish of door panels.

[0006] Therefore, there is an identified need for a technical solution that resolves these Petition 870250006424, dated 01 / 27 / 2025, page 10 / 21 2 / 6 problems, offering a fastening that is efficient, discreet and allows greater design flexibility, while improving usability and reducing the costs associated with the production and assembly of the component.

[0007] Some prior art documents have attempted to solve this problem, as can be seen below:

[0008] JP2024179795 - This prior art discloses a door panel having a hole in the panel formed at the top of the opening and a lower mounting section for securing the lower end of the door module to the bottom of the opening. The upper end of the regulating rail is configured so that the screw is inserted into the hole in the panel from the outside of the vehicle. In the door module mounting structure, the upper end of the regulating rail is fixed to the door panel, while the lower end of the regulating rail and the lower end of the cover element are fixed to the lower mounting section from the inside of the vehicle.

[0009] JP6264243 - This prior art discloses an internal door panel fastening part that has the form of a flat plate extending vertically from the vehicle, with a mounting hole in the shape of an opening located in its central part. The internal fastening part is coupled to a cylindrical boss-shaped mounting section that extends across the width of the vehicle, positioned at the rear of the lower vertical portion of the wall. The boss mounting section is located at the rear of the vehicle, behind the door trim, and is integrated as part of a lower plate. The internal fastening part is fixed to the lower vertical portion of the wall by inserting the boss into the mounting opening, from the inside of the vehicle cabin to the outside, with the peripheral edges of the mounting opening and the boss joined by ultrasonic crimp welding or a similar method.

[0010] Existing solutions fail to develop fastening devices for vehicle door panels that combine structural efficiency, ease of assembly, and compatibility with different design configurations, meeting the technical and aesthetic requirements of the automotive sector. The present invention proposes to solve these limitations by offering a technical alternative that integrates these characteristics in an efficient and innovative way. Objectives of the Invention
