Battery Relay Cavity Integration to Cut Power Distribution Bulk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution apparatuses have large design margins and space waste, leading to a large size and inefficiencies in miniaturization.
Innovation Solution
A power distribution apparatus with a base and relay design that fixes the relay in an accommodating cavity, utilizing inner walls to replace the relay's shell structure, and incorporates structural adhesives and protrusion structures for enhanced positioning and protection, reducing space and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the relay is equipped with its own shell structure for protection, then the relay is protected, but the overall size and weight of the power distribution apparatus increases
Solution Approach 1:
The patent merges the relay shell function with the base structure. The base's accommodating cavity serves dual purposes: it holds the relay and provides the protective shell function that would otherwise require a separate relay housing. This integration eliminates redundant structures and reduces overall weight.
Solution Approach 2:
The base structure is designed to perform multiple functions simultaneously: it accommodates the relay, provides mechanical protection through its cavity walls, and serves as the mounting structure. This multi-functionality eliminates the need for dedicated relay shell components.
2Reliability
If the relay is equipped with its own shell structure, then the relay is protected, but the design margin and space waste increase
Solution Approach 1:
The protective shell function is merged into the base structure. The accommodating cavity of the base serves as the protective enclosure for the relay, eliminating the need for a separate relay shell and reducing overall apparatus volume.
Solution Approach 2:
The relay is nested within the accommodating cavity of the base, which provides the protective function. This nesting arrangement allows the relay to be housed within the existing base structure without requiring additional external shell components.
3Stability of the object's composition
If the relay is fixedly mounted in the accommodating cavity, then the relay is securely positioned, but the assembling complexity increases
Solution Approach 1:
The base structure is segmented to include specific positioning features such as protrusions or recesses that engage with corresponding features on the relay. This segmentation allows for straightforward mechanical engagement and secure mounting without complex assembly procedures.

AI summary
The present application relates to the field of batteries, and provides a power distribution apparatus (30), a battery (1), and an electrical device. The power distribution apparatus (30) includes a base (32) and a relay (312). The base (32) forms an accommodating cavity (321). The relay (312) includes a switch unit (3124), and at least part of an outer wall of the switch unit (3124) is exposed in the accommodating cavity (321). An inner wall of the accommodating cavity (321) is connected to the relay (312) to fix the relay (312) to the accommodating cavity (321). The power distribution apparatus (30) can fix the relay (312) in the accommodating cavity (321). Furthermore, the relay (312) fixed in the accommodating cavity (321) can use the inner wall of the accommodating cavity (321) to replace its own shell structure. Therefore, the own shell structure of the relay (312) can be omitted, an integrated and miniaturized power distribution apparatus can be formed, and design margin and space waste can be reduced.
