Elastic Tolerance Compensation Assembly for Chassis Guard Plate Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connecting mechanisms for chassis guard plates on vehicle chassis fail to maintain a fixed positional relationship due to relative displacement between the subframe and vehicle body, leading to potential damage from exposure of chassis components.
Innovation Solution
A tolerance compensation device comprising a first compensation member with a sleeve and a second compensation member with elastic clamping portions, along with an optional isolation member, that allows for snap-fit connections and elastic deformation to accommodate displacement, ensuring the chassis guard plate remains stationary relative to the vehicle body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional connecting mechanisms are used to install chassis guard plates, then installation is quick and convenient, but the positional relationship between the guard plate and vehicle body cannot be maintained due to subframe displacement
Solution Approach 1:
The connecting mechanism is divided into multiple segments: a first connecting member fixed to the subframe, a second connecting member fixed to the guard plate, and an elastic compensation member connecting them. This segmentation allows each component to perform its specific function - the elastic compensation member absorbs displacement while the other members maintain fixed connections, solving the contradiction between easy installation and positional stability.
Solution Approach 2:
The elastic compensation member changes its physical parameters (length, shape) in response to subframe displacement. By allowing the compensation member to deform elastically within a specific range, the system adapts to position changes without compromising the overall structural stability or requiring complex adjustment mechanisms.
2Reliability
If rigid connecting mechanisms are used to maintain fixed position, then positional relationship is stable, but the mechanism cannot accommodate subframe displacement and may cause damage
Solution Approach 1:
The connecting mechanism transitions from a static rigid structure to a dynamic system with an elastic compensation member that can deform. This dynamic element allows the connection to adapt to displacement conditions while maintaining overall stability, preventing damage by absorbing stress rather than transmitting it to the guard plate or subframe.
Solution Approach 2:
The elastic compensation member acts as a pre-designed cushioning element that anticipates and absorbs displacement forces before they can cause damage to the guard plate or subframe. By incorporating this compliant element in advance, the system protects itself from potential harm while maintaining positional stability.
3Reliability
If tolerance compensation device with elastic deformation is used, then displacement is accommodated and position is maintained, but device complexity increases
Solution Approach 1:
The elastic compensation member is designed as a simple, inexpensive component that can be easily replaced if needed. Rather than using a complex, expensive adjustment mechanism, the patent employs a straightforward elastic element that achieves the same functional result with minimal complexity, making the overall system more economical and easier to manufacture.

AI summary
A tolerance compensation device including a first compensation member having a sleeve and a bottom seat arranged around one end of the sleeve, the sleeve defining a receiving passage; and a second compensation member including a base portion and an elastic clamping portion connected to the base portion, the base portion defining an aperture. The sleeve of the first compensation member is detachably connected at its other end to the base portion of the second compensation member, with the receiving passage aligned with the aperture. The elastic clamping portion of the second compensation member cooperates with the bottom seat of the first compensation member to clamp a first component (e.g., a vehicle chassis guard plate) therebetween. By employing this tolerance compensation device when connecting the first component to a second component (e.g., a vehicle subframe), the device compensates for displacement tolerances generated between the second component and the first component during vehicle operation, thereby preventing the first component from moving with the second component.
