Split Protective Cover for Battery Ventilation Mounting Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery housings with ventilation devices are prone to impaired ventilation function and mounting/dismounting difficulties, especially in harsh environments.
Innovation Solution
A protective cover for the ventilation device of a battery housing, featuring a flange portion and a split design with two separate parts that form an airflow duct, allowing for easy attachment and detachment, and includes features like protrusions and fastening means for secure fit and orientation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover is provided for the ventilation device, then protection against harsh environment is improved, but mounting and dismounting becomes more complex
Solution Approach 1:
The protective cover is divided into at least two separate parts that can be independently mounted and removed. This segmentation allows the cover to be easily installed and taken off without requiring complex tools or procedures, while still providing comprehensive protection when assembled.
2Strength
If a protective cover with single-piece design is used, then structural integrity is improved, but mounting and dismounting becomes difficult
Solution Approach 1:
The protective cover is divided into at least two separate parts that can be independently mounted and removed. This segmentation allows the cover to be easily installed and taken off without requiring complex tools or procedures, while still providing comprehensive protection when assembled.
3Reliability
If the protective cover is designed to fully cover the ventilation device, then ventilation protection is improved, but access for maintenance becomes difficult
Solution Approach 1:
The protective cover is divided into at least two separate parts that can be independently mounted and removed. This segmentation allows the cover to be easily installed and taken off without requiring complex tools or procedures, while still providing comprehensive protection when assembled.

AI summary
The invention relates to a protective cover (1) for protecting a ventilation device (110) of a battery housing (1000), wherein the ventilation device (110) comprises an airflow opening (102) which is arranged to provide an airflow between an inside of the battery housing (1000) and an external environment, and wherein the battery housing (1000) and/or the ventilation device (110) comprises a first flange portion (104) which extends around the airflow opening (102), and which further extends in a radially outward direction with respect to the airflow opening (102), the protective cover (1) comprising: - an airflow duct (10) extending between a first opening (12) and a second opening (14), wherein the first opening (12) of the airflow duct (10) is arranged to be fluidly connected to the airflow opening (102) of the ventilation device (110) and wherein the second opening (14) is arranged to be fluidly connected to the external environment, - an attachment portion (20) associated with the first opening (12) for attaching the protective cover (1) to the first flange portion (104) so that the protective cover (1) covers the airflow opening (102), wherein the attachment portion (20), when being attached to the first flange portion (104), extends around the airflow opening (102), - wherein the protective cover (1) comprises at least two separate parts (30, 40) which are releasably attachable to each other and arranged so that the attachment portion (20) can be split into at least two separate attachment sections (22, 24) to allow the protective cover (1) to be attached to and released from the first flange portion (102). The invention also relates to a ventilation arrangement (100), a battery housing (1000) and a vehicle (200).
