Vehicle Charging Base Guide Mechanism for Stable Open Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The loading floor of a vehicle, when opened to access a space beneath, often falls shut due to gravity, requiring user intervention to maintain the open position, and handling the transition from closed to open positions is cumbersome.
Innovation Solution
A motor vehicle with a holding device featuring a guide element and a support element, where a bearing element moves along the guide element to an end position, forming an acute angle with the vertical, and is supported by the support element to maintain the open position, allowing easy rotation and pivoting for user-friendly operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the charging base is designed to rotate between a stowed position and an extended position to enable charging of vehicles parked at angles, then charging versatility is improved, but the mechanical complexity and potential failure points increase
Solution Approach 1:
The charging base is designed to rotate dynamically between a stowed position (aligned with the vehicle direction of travel) and an extended position (positioned laterally of the vehicle). This dynamic repositioning allows the base to adapt to vehicles parked at various angles while maintaining a relatively simple mechanical structure through controlled motion rather than complex static mechanisms
Solution Approach 2:
The charging system is segmented into a movable charging base and a stationary charging pile. The base can be independently positioned and rotated to achieve optimal charging alignment, separating the functions of power delivery (stationary pile) and vehicle access adaptation (movable base)
2Ease of operation
If the charging base is extended laterally of the vehicle to enable charging, then charging accessibility is improved, but the risk of collision with the vehicle increases
Solution Approach 1:
The system performs preliminary detection of the vehicle's presence and position before extending the charging base laterally. The rotating mechanism is controlled to move the base into the extended position only after confirming it is safe to do so, reducing collision risk while maintaining charging accessibility
Solution Approach 2:
The charging base acts as an intermediary element between the stationary charging pile and the vehicle. It can rotate to an extended position that optimizes the charging connection while maintaining a safe distance from the vehicle body, mediating between the need for accessibility and collision avoidance
3Adaptability or versatility
If the charging base is designed to rotate to different positions, then charging flexibility is improved, but the control system complexity increases
Solution Approach 1:
The charging base incorporates sensors and control mechanisms that enable it to autonomously detect its position, determine the optimal charging alignment, and rotate to the appropriate angle without requiring complex external control systems. The base serves itself by automatically navigating to the correct position based on vehicle detection
Solution Approach 2:
The system uses feedback from sensors detecting the charging vehicle's position and orientation to control the rotation of the charging base. The control mechanism receives feedback about the current base position and the detected vehicle parameters, automatically adjusting the base angle to achieve optimal charging alignment

AI summary
The invention relates to a motor vehicle with a charging base (14) which can be brought from a closed position into an open position. A holding device (30) for holding the charging base (14) in the open position comprises a guide device (32), and by bringing the charging base (14) into the open position, a bearing element (38) of the charging base (14) can be moved along the guide device (32) into an end position (42) in which the bearing element (38) is arranged lower in the vertical direction (z) of the motor vehicle than when the charging base (14) is in the closed position. The bearing element (38) can be moved from a starting position, which the bearing element (38) assumes in the closed position of the charging base (14), into an intermediate position (40) by rotating the bearing element about a pivot axis of the charging base (14), and the bearing element (38) can be moved from the intermediate position (40) into the end position (42). The invention additionally relates to a method for bringing the charging base (14) into the open position.
