3results about How to "Quick battery swap" patented technology

This invention provides a battery pack bracket and an electric vehicle including the same, comprising a bracket body. The bracket body has at least one locking mechanism spaced apart along the length of the vehicle body. The locking mechanism is used to lock or unlock the battery pack in a vertical direction. The bracket body is connected to the vehicle body via a floating unit, allowing the bracket body to float vertically relative to the vehicle body. This invention uses a battery pack bracket to transfer the battery pack. The bracket body and the vehicle body can float vertically relative to each other via the floating unit, thereby mitigating the damage caused by increased torque or vibration directly transmitted to the battery pack when the vehicle body is twisted or driving on bumpy roads, thus improving the battery pack's lifespan. Furthermore, the vertical attachment of the battery pack via the bracket increases the battery pack's battery swapping rate.

The application discloses a handheld underwater detection device with adjustable direction propulsion and belongs to the technical field of underwater operation equipment. The existing handheld underwater detection device completely relies on manpower movement, and problems such as no power assistance, power and detection being unable to be coordinated exist. The application comprises a main body structure, a quick-release battery assembly, a sensing unit, an interactive display module and an underwater propulsion module. The main body structure comprises a main shell and a handheld ring connected with the main shell. The quick-release battery assembly is installed on the main body structure, provides power for the device and realizes quick release of the battery. The sensing unit comprises a detection imaging assembly and a multi-source fusion positioning navigation module. The interactive display module comprises a display screen and control buttons arranged on the top surface of the main body structure. The underwater propulsion module comprises an underwater steering engine fixed below the main body structure and an underwater propeller connected with the output end of the underwater steering engine, and the underwater steering engine is used for driving the underwater propeller to realize adjustable pitch angle. The application realizes adjustable direction autonomous propulsion of the handheld underwater detection device, integrates detection, navigation and power assistance into one, and is convenient for operation.
