Battery Clamp With Inclined Surface For Vibration Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery holding structures fail to securely hold batteries when the end part floats upward due to vibrations or inertial forces, as the holding force is released or lowered due to vertical drag acting on the clamp, causing disengagement.
Innovation Solution
The battery holding structure features a clamp with a first contacting part that presses the battery's inclined surface, a standing part, and a fastening part positioned outside the battery, allowing the clamp to swing and distort in a way that follows the upward movement of the battery, ensuring continuous holding by positioning the contact point and fixing point to maintain contact even when the battery floats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clamp presses the brim obliquely from above to fix the battery, then the battery can be restricted from moving and held securely under normal conditions, but when the end part of the battery floats upward due to vibrations or inertial forces, the vertical drag causes the clamp to swing or distort and separate from the brim, releasing the holding force
Solution Approach 1:
The clamp is designed with a dynamic structure that allows it to swing or distort in response to vertical drag forces. Instead of being a rigid fixed structure, the clamp can move within certain limits to accommodate the upward floating of the battery end part, maintaining continuous contact through controlled movement rather than rigid resistance
Solution Approach 2:
The positional relationship between the contact point and fixing point is specifically designed so that the normal line passes inside the fixing point on the battery side. This geometric parameter configuration ensures that when vertical drag occurs, the resulting moment causes the clamp to swing in a direction that maintains contact with the brim rather than separating from it
2Device complexity
If the normal line of the inclined surface passes outside the fixing point as in conventional structures, then the clamp structure is simple, but when receiving vertical drag, the clamp swings in a direction that separates from the brim, causing disengagement
Solution Approach 1:
The critical parameter change is the positional relationship between the contact point and fixing point. By positioning the normal line to pass inside the fixing point on the battery side rather than outside it, the patent changes the moment arm configuration. This parameter change transforms the swing direction of the clamp under vertical drag, converting a harmful separation motion into a beneficial contact-maintaining motion, thereby achieving reliable continuous holding without complicating the overall clamp structure

AI summary
A battery holding structure includes a battery (10) having a brim (18), a carrier (12) having a main body (20) accommodating the battery (10) and a flange (24) extending outward from an upper end of the main body (20), and a clamp (14) for fixing the battery (10) to the carrier (12). An upper surface of the brim (18) is an inclined surface (19) that extends downward and outward. The clamp (14) includes a first contacting part (30) that comes into contact with the inclined surface (19), a first standing part (32) standing from the first contacting part (30), and a fastening part (38) to be fastened to the flange (24). A normal line of the inclined surface (19) passing through a contact point between the inclined surface (19) and the first contacting part (30) passes inside a point (Ps) where the fastening part (38) is fixed to the flange (24) so as to be positioned on a battery side.
