Industrial Truck Battery Securing Brace for Space-Saving Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery securing mechanisms in industrial trucks require a large amount of space due to the need for stability, which is not efficiently utilized in the vehicle's design.
Innovation Solution
A securing bracket system that uses an engagement section, a fastening element, and a holding section with elastic deformation to secure the battery pack, minimizing space usage by leveraging the interspace between the battery pack and the vehicle frame, and applying a tensioning force to maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a pivotable lever construction is used to secure the battery pack, then the required stability for securing the heavy battery pack is achieved, but a relatively large amount of space within the vehicle housing is required
Solution Approach 1:
The securing bracket is divided into three functional segments: an engagement section that inserts into the frame, a holding section that provides the supporting region, and a fastening element that suspends in the frame. This segmentation allows each part to be optimized for its specific function while minimizing overall space requirements.
Solution Approach 2:
The securing bracket utilizes the vertical dimension by extending between the first frame part (lower) and second frame part (upper) in substantially vertical alignment. This vertical orientation maximizes the lever arm ratio and enables effective tensioning force application without requiring additional horizontal space in the battery compartment.
2Reliability
If the securing bracket exerts a high tensioning force on the battery pack, then the battery pack is held fixedly and the bracket cannot be released during operation, but a significant manual force is required to remove the bracket
Solution Approach 1:
The fastening element is designed to be suspendable in the second frame part, allowing it to pivot between a secured position (where it engages the frame) and a removed position (where it can be manually extracted). This dynamic design enables the bracket to transition from a locked state during operation to an easily removable state for maintenance.
Solution Approach 2:
The supporting region is integrated into the holding section itself rather than being a separate component. This merging means the same structural element that provides mechanical support also serves as the point of application for tensioning force, eliminating the need for additional locking mechanisms and simplifying the removal process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively secures the battery pack with a high tensioning force using minimal space, ensuring the bracket cannot be released during operation and allowing for easy manual removal, thus optimizing space utilization and operational safety.
Implementation Method 1
the fastening element can be suspended in the second frame part with elastic deformation of the holding section
Implementation Method 2
the securing bracket is designed in such a way that, in the securing position, it exerts a tensioning force which acts on the battery pack in the supporting region
Implementation Method 3
The counterforce to the pretensioning which is acting, which counterforce needs to be exerted for this purpose on the securing bracket by an operator, is critically determined on the basis of the lever arm ratio between the fastening element, the holding section and the engagement section

AI summary
The invention relates to an electric vehicle, especially an industrial truck comprising at least one securing brace (28) for a battery block (24) that is accommodated in the vehicle (10). The securing brace (28) encompasses an engaging section (30) that can be inserted into a first frame part (34) of the vehicle (10), a fastening element (38, 56) that can be hooked into a second frame part (40), and a retaining section (44) that extends therebetween. A supporting section (70) of the securing brace (28) at least partly rests against the battery block (24) in a securing position in which the securing brace (28) is inserted in the vehicle. Said supporting section (70) of the securing brace (28) is located in the area of the retaining section (44) or in the area of the transition between the retaining section (44) and the engaging section (30) and forms a bearing of the securing brace (28) on the battery block (24) such that the fastening element (38) can be hooked into the second frame part (40) while the retaining section (44) is elastically deformed and the engaging section (30) is in the inserted state in the first frame part (34).
