Emergency Starting Power Supply For Vehicle
Patent No. US12336125 (titled "Emergency Starting Power Supply For Vehicle") was filed by Shenzhen Zhanpusida Technology Co Ltd on Oct 29, 2024.
What is this patent about?
’125 is related to the field of emergency starting power supplies for vehicles. These devices are designed to provide a portable solution for jump-starting a vehicle with a dead battery. Existing solutions suffer from mounting instability and poor reliability of internal components like the power source, circuit board, and output terminals, leading to a reduced lifespan.
The underlying idea behind ’125 is to improve the mechanical stability and reliability of an emergency starting power supply. This is achieved by providing a robust mounting system within the device's shell. Specifically, the output terminal, which delivers the high current needed for starting a car, is mechanically secured to the shell using a detachable coupling mechanism and further constrained by a protrusion on the shell.
The claims of ’125 focus on an emergency starting power supply comprising a shell with an internal space and a mounting feature, a power source and circuit board inside the space, and an output terminal electrically connected to the power source. Crucially, the output terminal is detachably connected to the mounting feature via a coupling mechanism , and a protrusion on the shell limits the terminal's movement.
In practice, the invention uses a two-part shell. One part houses the battery and electronics, while also providing a mounting structure. The output terminal, which connects to the car battery, is secured to this mounting structure using a sliding or screw-based coupling. The second shell part includes a protrusion that physically blocks the output terminal from moving, ensuring a stable and reliable connection even under vibration or impact.
This design differentiates itself from prior approaches by providing a dedicated and mechanically robust mounting system for the output terminal. Instead of simply relying on electrical connections or adhesives, the invention uses a combination of a detachable coupling and a physical constraint to ensure the output terminal remains securely in place. This reduces the risk of failure and extends the overall lifespan of the emergency starting power supply.
How does this patent fit in bigger picture?
Technical landscape at the time
In the early 2020s when ’125 was filed, emergency starting power supplies for vehicles were at a time when integrating multiple functions into portable power sources was a common design goal. At a time when hardware or software constraints made efficiently and reliably mounting internal components like power sources, circuit boards, and output terminals within a compact shell non-trivial.
Novelty and Inventive Step
The examiner approved the application because claims 1-20 were allowable over the prior art of record.
Claims
This patent contains 20 claims, with claim 1 being the only independent claim. Independent claim 1 is directed to an emergency starting power supply for vehicles, detailing its components and their arrangement. The dependent claims generally elaborate on specific features, configurations, and additional components of the emergency starting power supply described in the independent claim.
