Sliding Door Wire Guide Bracket Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of bracket shapes in electrical wire guide apparatuses for sliding doors leads to increased costs due to complex die molding requirements, which complicates the assembly and attachment process.
Innovation Solution
A simplified bracket design where the body-side bracket is detachably locked to a receiving portion on the sliding door, eliminating the need for a locking structure on the door-side bracket, and incorporating a restriction portion to prevent tilting and ensure stable locking, allowing for reduced deformation and efficient conveying and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hanging structure with recession and protrusion is used to temporarily assemble the body-side bracket to the door-side bracket, then the brackets can be assembled together, but both brackets need to be provided with portions for constituting the hanging structure, leading to complex shapes and increased die molding costs
Solution Approach 1:
The invention extracts the locking function from the door-side bracket and relocates it to the body-side bracket. The body-side bracket is provided with a lock portion that can be locked to a receiving portion on the sliding door, while the door-side bracket is simplified to only have a fixing portion for fixed attachment to the sliding door. This separation of functions eliminates the need for complex locking structures on both brackets, thereby simplifying the door-side bracket shape and reducing die molding costs.
2Reliability
If the body-side bracket is fixed to the door-side bracket using a hanging structure, then the assembly is stable, but the shapes of both brackets become complex, increasing manufacturing costs
Solution Approach 1:
The invention introduces a receiving portion on the sliding door as an intermediary element. The lock portion on the body-side bracket locks to this receiving portion on the sliding door, rather than locking to the door-side bracket. This intermediary structure enables stable locking while keeping both the body-side bracket and door-side bracket shapes simple, as neither bracket needs to provide both locking and fixing functions.
3Adaptability or versatility
If the electrical wire guide body undergoes curving deformation during door opening and closing, then the wire harness can accommodate door movement, but the body-side bracket requires movement in the front-rear direction, increasing assembly complexity
Solution Approach 1:
The invention performs preliminary positioning by providing a lock portion on the body-side bracket that can be locked to a receiving portion on the sliding door before final assembly. This preliminary locking action establishes the correct position and orientation of the body-side bracket, reducing the movement required during final assembly and simplifying the assembly process while maintaining the wire harness's ability to accommodate door movement through curving deformation.

AI summary
A sliding door electrical wire guide module includes a sliding door and an electrical wire guide apparatus that are integrated with each other. The electrical wire guide apparatus includes: an electrical wire guide body for spanning a distance between a vehicle body and the sliding door and that is capable of undergoing curving deformation; a door-side bracket that is coupled to one end portion of the electrical wire guide body and is fixed to the sliding door; a body-side bracket that is coupled to the other end portion of the electrical wire guide body and is to be attached to the vehicle body, and a lock portion that is formed on the body-side bracket and is detachably locked to a receiving portion provided on the sliding door.
