The utility model discloses a kind of protective cases for intelligent equipment, it is related to protective case technical field, including body part, side part, first guide hole, second guide hole, charging part, card storage area and variable gasket, the side part is annular design, the side surface, upper surface and lower surface of covering body part, and first guide hole is opened in the middle of the back surface of body part, and second guide hole is located in the middle circular place of first guide hole, the charging part is located in the back of body part, and the middle of charging part is provided with variable gasket located in the back of body part.The utility model discloses, when protective case for intelligent equipment is in use, user can stably carry out MagSafe wireless charging even in the state of card storage, while maximumly reduce charging efficiency decline and heating and other problems.This is because the magnet arrangement and shielding structure design arranged inside mobile phone shell device are used to keep charging performance.

A battery pack and a vehicle lower structure provided with the same are provided. The battery pack (20) is provided with a battery (21), a case (22) that houses the battery (21), and a plurality of connectors (24, 25, 26, 27). When a specific direction in a direction perpendicular to a vehicle up-down direction is set as a first direction, the plurality of connectors (24, 25, 26, 27) respectively protrude from the case (22) to the first direction side.

The application provides a deep seam mining method and system in a submerged environment. A large-diameter shaft is drilled to a target seam and cemented, the wellhead is sealed and pressurized, and water is injected into the wellbore to create a submerged environment. Then, an underwater mining robot is used to crush the ore in situ in the submerged environment and simultaneously implement roof support as needed. A water-gas mixed lifting system is used to lift the ore to the ground, and the resource is finely classified and purified. By creating a submerged environment, the static pressure of water can balance part of the ground pressure, reducing the impact of stress changes on rock stability, reducing safety accidents such as harmful gas outburst, and reducing tool wear by providing sufficient water supply for high-pressure water jet rock breaking operations. At the same time, the "submerged environment in-situ crushing-pipeline transportation-ground separation" integrated technology reduces the cost of building a well, making it easier to achieve automation and intelligent control for continuous mining and reduce operating costs.
