- the distribution of the liquid metal 6 within the flexible impact-resistant pad 2 can be relatively uniform. Not only a higher degree of comfort for wearing can be provided in response to detecting an un-fall-down of the human body, but also a uniform and comprehensive high-strength protection can be provided when the human body falls down.
- the liquid metal 6 in the spring-like sub-channels 81 may change into a solid phase state, which can have a certain elastic property.
- the liquid metal 6 in the solid phase state in the spring-like sub-channels 81 can play a certain buffer effect and/or damping effect, thereby further improving the protective properties of the disclosed protective gear.

Since the liquid phase state of the liquid metal 6 cannot be affected by the ambient temperature, the disclosed protective gear can consistently provide a high degree of comfort for wearing to the user.
- the protective gear can be a ski knee brace.
- the melting point of the liquid metal 6 in the flexible impact-resistant pad 2 is 25° C. Since the temperature of a ski field is low, the ambient temperature is insufficient to maintain the liquid phase state of the liquid metal 6 . Therefore, in response to detecting an un-fall-down of the human body, the heating circuit 7 can be in the operation state to heat the liquid metal 6 to keep a temperature slightly higher than its melting point, so that the liquid phase of the liquid metal 6 can be maintained.
- the heating circuit 7 can be switched off, and the phase-change controller 3 can be switched on to cool the liquid metal 6 into a solid phase state.

- the control circuit 5 can activate one or more corresponding flexible impact-resistant pads 2 .
- Other flexible impact-resistant pad(s) can continually maintain a flexible state. As such, the degree of comfort for wearing can be further improved.

- the operation control apparatus of the protective gear may be integrated with the protective gear, and become a part of the protective gear. In some alternative embodiments, the operation control apparatus may be located separately from the protective gear. In some other embodiments, a first part of the operation control apparatus may be located separately from the protective gear, and a second part of the operation control apparatus of the protective gear may be integrated with the protective gear.
- a software application for controlling the protective gear may be installed in a smart watch that is worn by the user wearing the protective gear. And there is a wireless communication link between the smart watch and the protective gear to realize information communication and control instruction transmission.
- the phase-change controller can cool the phase-change material such as a liquid metal in the impact-resistant pad into a solid phase state at the moment of falling.
- the protective gear can be controlled to provide a high protection degree for the human body portion wearing the protective gear.
- the phase-change material such as the liquid metal in the flexible impact-resistant pad can be controlled to keep a liquid phase state to provide a desirable flexibility, which has a high degree of comfort for wearing to the user. Therefore, the disclosed operation control apparatus can control the protective gear to provide a protection as well as comfortable protection to the user.
- protective gears Accordingly, protective gears, operating control methods of the protective gears, and operating control apparatuses of the protective gears are provided.
