Problem
The challenge of welding a conductive sheet to a battery cell is hindered by a shielding part in traditional battery units, leading to false soldering and poor electrical connections due to misalignment and distance issues.
Innovation Solution
A battery unit design featuring a bracket with a base shell having receiving grooves on both sides and a stopper that covers the edge of the battery cell, ensuring electrodes are in the same plane for improved bonding, along with a conductive sheet positioned through holes to facilitate stable electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a battery module uses a conventional holder structure with separate positioning components, then the assembly process becomes complex and time-consuming, but the structural stability may be maintained
Solution Approach 1:
The patent integrates the positioning function directly into the holder body structure. The holder includes positioning protrusions that engage with positioning grooves on the battery pack, eliminating the need for separate positioning components. This merging of positioning and holding functions into a single integrated structure reduces assembly steps and improves assembly efficiency while maintaining structural stability.
Solution Approach 2:
The holder body is designed to perform multiple functions simultaneously: it provides mechanical support, enables thermal dissipation through heat dissipation protrusions, and ensures precise positioning through integrated positioning features. This multi-functional design eliminates the need for separate components for each function, thereby simplifying the overall structure and improving assembly efficiency.
2Productivity
If the holder structure is simplified for easier assembly, then assembly efficiency improves, but the stability and reliability of the battery module may deteriorate
Solution Approach 1:
The positioning and support functions are merged into the holder body structure itself. The holder includes positioning protrusions that engage with positioning grooves on the battery pack, providing stable positioning without requiring separate positioning components. This integrated design maintains reliability while simplifying the overall structure for easier assembly.
Solution Approach 2:
The holder is designed with a composite structure that includes a holder body and integrated positioning features. The holder body provides overall support while integrated positioning protrusions and heat dissipation protrusions provide specialized functions. This composite structural approach ensures stability is maintained even with a simplified overall design.
3Manufacturing precision
If separate positioning components are used in the holder, then positioning precision may be maintained, but the number of parts increases and assembly becomes more complex
Solution Approach 1:
The positioning function is merged directly into the holder body structure through integrated positioning protrusions. These positioning protrusions engage with positioning grooves on the battery pack to provide precise positioning without requiring separate positioning components. This reduces the total number of parts while maintaining positioning precision through the integrated design.
4Adaptability or versatility
If the holder structure is made more complex with additional features, then functional performance improves, but the manufacturing cost and assembly time increase
Solution Approach 1:
The heat dissipation function is merged into the holder body structure through integrated heat dissipation protrusions. These protrusions extend from the holder body and provide thermal pathways without requiring separate heat dissipation components. This allows the holder to perform both mechanical support and thermal management functions simultaneously, improving functional performance without increasing assembly time.
Solution Approach 2:
The holder body is designed as a multi-functional component that provides mechanical support, positioning, and heat dissipation all in one structure. The integrated heat dissipation protrusions enable thermal management while the holder maintains its primary support and positioning functions. This multi-functionality improves overall system performance without requiring additional components or assembly steps.

AI summary
The embodiment relates to the technical field of energy storage power supplies, in particular to a bracket body, a bracket, a battery unit and an energy storage power supply. The bracket includes a base shell and a stopper, wherein the base shell is provided with a receiving groove for receiving a battery cell, the receiving groove runs through a first surface and a second surface of the base shell, and the first surface and the second surface are two opposite surfaces of the base shell; the stopper includes a connecting part and a resisting part, the connecting part is fixed to the first surface of the base shell and avoids the receiving groove, and the resisting part is connected to the connecting part; and the resisting part corresponds to the receiving groove and covers part of an edge of the receiving groove. In this way, the stopper abuts against an end of the battery cell, so that the battery cell can be installed on the bracket body, which solves the problem that a conductive sheet and a battery cell are hard to weld when a battery cell is fixed through a shielding part for an existing bracket.
