Utility Vehicle Tail Lamp Bolt Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of utility vehicles with tail lamps mounted on the rear edge surface of the cargo bed exposes the bolt head, making it susceptible to external contact and compromising the vehicle's appearance.
Innovation Solution
The tail lamp is secured to the side wall of the cargo bed using a bolt oriented in the vehicle width direction, with the bolt head hidden by the side wall unit, preventing exposure and enhancing the vehicle's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the tail lamp is secured to the rear edge surface of the cargo bed using a bolt inserted from behind, then the tail lamp can be firmly mounted, but the bolt head becomes exposed and spoils the appearance of the vehicle
Solution Approach 1:
The invention extracts the bolt head from the visible area by changing the insertion direction. Instead of inserting the bolt from behind the cargo bed (which exposes the head), the bolt is now inserted from the side wall in the vehicle width direction, taking the protruding head out of the harmful visible position and eliminating the appearance problem while maintaining mounting strength
2Ease of manufacture
If the tail lamp is mounted on the rear end portion of the side wall, then wiring becomes easier, but the bolt head remains exposed to external contact
Solution Approach 1:
The invention extracts the bolt head from the exposed position on the rear edge surface and relocates it to the internal space of the side wall. By inserting the bolt from the side in the vehicle width direction, the head is taken out of the environment behind the vehicle, eliminating both the appearance problem and the risk of external contact while preserving the wiring advantages of side wall mounting

AI summary
A utility vehicle includes a vehicle body frame and a cargo bed supported by the vehicle body frame, the cargo bed including a side wall unit. The side wall unit includes a side wall, a tail lamp mounted on a rear end portion of the side wall, and a bolt including a shaft portion and a head portion. The tail lamp is secured to the side wall by the bolt oriented in a vehicle width direction. The head portion of the bolt is hidden by a part of the side wall unit when viewed from behind.
