Separate Battery and Spare Tire Mounting Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle mounting structures for batteries and spare tires face challenges in accurately positioning the battery, leading to increased assembly time and risk of battery separation during collisions, as well as difficulties in restricting the battery's position and transmitting loads from the spare tire.
Innovation Solution
A structure featuring separate battery and tire mounting brackets, with vehicle body brackets that restrict the battery's left and right position, and a tire mounting bracket that isolates the spare tire's load, ensuring the battery remains secure during collisions by fracturing the tire bolt first.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery and spare tire are mounted using a shared bracket structure, then the device complexity is reduced, but the reliability deteriorates because the battery may separate during rear-end collisions
Solution Approach 1:
The patent divides the mounting system into separate functional components: a battery bracket for securing the battery and a tire mounting bracket for securing the spare tire. This segmentation allows each bracket to be independently optimized for its specific function, with the battery bracket having enhanced collision resistance features while the tire bracket handles tire-specific mounting requirements.
2Ease of manufacture
If the battery is mounted without position restriction, then the ease of manufacture is improved, but the manufacturing precision deteriorates because the battery cannot be positioned accurately
Solution Approach 1:
The battery bracket incorporates self-positioning features such as guide rails or positioning pins that automatically guide the battery into the correct position during installation. This eliminates the need for complex external positioning equipment while ensuring accurate battery placement, allowing workers to simply place the battery onto the bracket without requiring precise measurement or adjustment.
3Area of stationary object
If the battery and spare tire are mounted in close proximity, then the area utilization is improved, but the harmful factors increase because load from the spare tire may be transmitted to the battery
Solution Approach 1:
The patent introduces a load-isolating structure between the battery bracket and tire mounting bracket, such as a separate mounting plate or damping element, that prevents force transmission from the tire to the battery. This intermediary component absorbs or redirects collision forces, ensuring that even when mounted in close proximity, the battery is protected from harmful loads generated by tire movements or collisions.

AI summary
A structure for mounting a battery and a spare tire may include a battery bracket fixing the battery to an accommodating compartment recessed in a rear floor of a vehicle, and a tire mounting bracket fastened to the spare tire, disposed at an upper side of the battery, through a tire bolt, and fixing the spare tire to the rear floor, in which the battery bracket and the tire mounting bracket are separated so that a load applied to the spare tire is not transmitted to the battery.
