TESLA MODEL 3 (2019-2022) ASSEMBLY - TRUNK FLOOR 1776527-SC-A (Aluminum Alloy)

Core Functionality

• Structural Foundation for Trunk Storage: As the primary surface of the trunk, this assembly serves as the base on which cargo, luggage, or other items are placed. It provides a flat, stable platform that supports the weight of stored items, ensuring they remain secure during vehicle movement—whether during acceleration, braking, or cornering.
• Integration with Trunk Structure: Beyond its role as a load-bearing surface, the trunk floor assembly connects to the surrounding trunk walls, hinges, and latch mechanisms, contributing to the overall structural integrity of the trunk compartment. It helps maintain the trunk’s shape and alignment, ensuring the trunk lid closes properly and seals tightly to prevent water, dust, or noise from entering the cabin.

Material: Aluminum Alloy Advantage

• High Strength-to-Weight Ratio: Aluminum alloy is both strong enough to support heavy loads (such as luggage or equipment) and significantly lighter than steel. This reduces the vehicle’s overall weight, which aligns with Tesla’s focus on energy efficiency and extended range for electric vehicles.
• Corrosion Resistance: Unlike steel, aluminum naturally forms a protective oxide layer, making it resistant to rust and corrosion—critical for a component exposed to potential moisture (e.g., wet items in the trunk) or environmental elements over time.
• Durability: The alloy’s toughness ensures the trunk floor can withstand repeated use, impacts from heavy items, and the vibrations of daily driving without warping, bending, or cracking.

Compatibility

Role in Trunk Utility

• Load Distribution: The flat, rigid surface distributes the weight of stored items evenly across the trunk, preventing localized stress on the vehicle’s rear structure.
• Aesthetic and Practical Finish: The aluminum alloy surface (likely treated with a protective coating) provides a clean, finished look to the trunk interior, complementing the Model 3’s minimalist design. It also simplifies cleaning, as spills or debris can be easily wiped away from the smooth surface.
