4results about How to "Increase buffer time" patented technology

This application relates to a flexible circuit board and an energy storage device. The flexible circuit board includes a fuse, a normally closed reed switch, a magnetic core coil, and a buffer delay circuit. The first end of the fuse is connected to a cell monitoring unit, and the second end of the fuse is connected to the first end of the normally closed reed switch. The second end of the normally closed reed switch is connected to the first end of the buffer delay circuit. The second end of the buffer delay circuit is connected to the first end of the magnetic core coil. The second end of the magnetic core coil is connected to the battery module, and the distance between the magnetic core coil and the normally closed reed switch is within a preset distance range. The magnetic core coil generates a magnetic field based on a continuous or pulsed surge current flowing through it. The normally closed reed switch is driven by the magnetic field to disconnect the connection between the cell monitoring unit and the battery module. The buffer delay circuit delays the connection between the battery module and the normally closed reed switch. This application provides protection against continuous or pulsed surges.

The utility model relates to a kind of head safety structure of air fryer, including pot body, the upper side of the pot body is detachably provided with main body, the hot air assembly that is arranged in the main body is sent hot air to the inner cavity of pot body, the top surface of the main body is equipped with the head handle that can slide up and down, the main body is equipped with the elastic contraction piece connected with head handle, the head handle can be elastically reset to retract position by elastic contraction piece in pull-up position, and the main body is also equipped with the switch element that is formed with head handle and constitutes dynamic touch cooperation, when head handle is in pull-up position or retract position, by the separation or contact between head handle and switch element, the disconnection or conduction of main body circuit is realized;This air fryer is pulled up head handle to lift main body at the same time, head handle releases the cooperation with switch element, switch element controls the circuit of main body to be disconnected momentarily, and the safety of air fryer is improved.

The application relates to a multifunctional airbag system for assisting a cross-medium vehicle to quickly cross media, which is suitable for a rotary-wing cross-medium vehicle and comprises an airbag buffer device, an airbag ballast device and a multi-airbag air volume unified control module. The airbag buffer device is arranged at the head of the cross-medium vehicle, the airbag ballast device is arranged at the middle section of the cross-medium vehicle, and the multi-airbag air volume unified control module is arranged at the tail of the cross-medium vehicle. The cross-medium vehicle is provided with three functions of underwater attitude adjustment, high-speed water entry buffering and rapid water exit assisting, the airbag ballast device replaces a traditional ballast water system, the inflation amount of the ballast airbag and the propeller power are controlled, and the functions of the cross-medium vehicle in underwater attitude adjustment, such as floating, diving and rotating, and the function of zero-energy consumption suspension in water can be realized.

The application discloses a method for recovering a rocket by splashing and falling on the sea, and the rocket comprises a first-stage rocket, an inter-stage section and a separation connecting mechanism for separably connecting the first-stage rocket and the inter-stage section; during splashing and falling of the rocket, the recovery method realizes quick unlocking and throwing away of the inter-stage section from the first-stage rocket through the separation connecting mechanism, so that the inter-stage section is prevented from participating in the second-time water-impact process, water dynamic force arms generated by overall tilting are reduced, buffer time is increased, buffer load is reduced, and the inter-stage section and the first-stage rocket are protected. The recovery method can reduce the second-time impact during the splashing and falling process and avoid introducing complex mechanisms for protection, so as to reduce the influence of the second-time water-impact on the rocket body.
