Vehicle Equipment Bracket Ribs to Prevent Collision Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle equipment attaching devices risk damaging adjacent equipment during vehicle collisions due to the edges of coupling brackets, and increasing the bracket thickness to prevent damage leads to increased weight.
Innovation Solution
A coupling bracket with a U- or H-cross-sectional shape and reinforcement ribs that protrude beyond the edges, absorbing the impact during collisions to protect rear-mounted equipment.

1Object-affected harmful factors
If the thickness of the coupling bracket sheet is increased to eliminate edges and prevent damage to rear-mounted equipment, then the protective function is improved, but the weight of the coupling bracket increases
Solution Approach 1:
The coupling bracket is segmented into multiple functional parts: side wall parts for structural support and a reinforcement rib for impact protection. This segmentation allows each part to be optimized independently - the main bracket body maintains thin-walled construction for weight efficiency, while the reinforcement rib provides targeted protection without requiring thickening of the entire bracket structure.
Solution Approach 2:
The reinforcement rib acts as an intermediary element between the coupling bracket and the rear-mounted equipment. During collision, the reinforcement rib makes contact with the equipment first, absorbing and distributing the impact force before it can reach the thin-walled bracket body, thus protecting the equipment without requiring the bracket itself to be thick.
2Strength
If a coupling bracket with U-cross-sectional shape extending in up-down direction is used, then the structural integrity is improved, but the edge at the rear end portion may contact and damage rear-mounted equipment during collision
Solution Approach 1:
The coupling bracket structure is divided into functional segments: the U-shaped side wall parts provide structural integrity for load-bearing, while the separately added reinforcement rib provides collision protection. This segmentation allows the bracket to maintain its lightweight thin-walled construction while adding protective functionality through the rib extension.
Solution Approach 2:
The reinforcement rib is designed to protrude beyond the rear end of the side wall parts, creating a preliminary protective barrier. During collision, this rib makes contact with rear-mounted equipment first, absorbing impact energy before it can reach the main bracket structure, thus preventing damage in advance.

AI summary
The present invention is an in-vehicle equipment attaching device that attaches onboard equipment to a vehicle frame extending in the longitudinal direction of a vehicle by using a linking bracket. The bracket has a first side wall part that is secured to a frame-side wall section, a second side wall part that is installed facing the first side wall part and that is secured to the onboard equipment, and a third side wall part, the bracket forming an approximate U shape or H shape in cross-section such that the vehicle-rearward side thereof forms an open section. The bracket furthermore has first reinforcing ribs that are arranged between the first side wall part and the second side wall part, rear end sections of the ribs protruding further rearward than a rear end section of the second side wall part.
