The utility model discloses a wireless charging device, which comprises a receiving coil, a receiving coil shell, a transmitting coil, a transmitting coil shell and a connecting piece, the receiving coil is arranged in the receiving coil shell; the transmitting coil is arranged in the transmitting coil shell; when the transmitting coil shell is moved to the receiving coil shell and the transmitting coil shell and the receiving coil shell are aligned to a preset position through the connecting piece, the transmitting coil and the receiving coil directly face each other and are in a matched state, and the gap and the offset between the transmitting coil and the receiving coil are smaller than or equal to a set threshold value. According to the utility model, the coil dislocation during charging can be reduced, the coil area can be reduced, the requirement for foreign matter detection can be reduced, and electromagnetic radiation can be reduced, so that the charging safety is ensured while the charging efficiency is ensured, and the manufacturing cost of the charging device is reduced.

The application discloses an automatic hard pipe double-sided folding label pasting device, and belongs to the technical field of label pasting. The device is a handheld gun type structure, comprising a detachable adhesive mechanism and a conveying mechanism. When in use, the operator aims the gun head at the car hard pipe, and the controller drives the motor to complete paper feeding, pressure pasting, negative pressure adsorption and peeling; then the operator manually presses the toggle bar, the connecting rod mechanism is driven to synchronously overturn the folding plate by 90 degrees, and the double-sided label is automatically centered, folded and pasted along the positioning groove matched with the hard pipe. The device is built-in lithium battery, supports wireless operation; the friction wheel and the elastic tension system ensure stable feeding; the quick release structure is convenient for maintenance. The application does not need to disassemble the hard pipe, is especially suitable for the label pasting of the space small and complex car-mounted pipeline site, significantly improves the pasting efficiency, precision and consistency, and has good practicality and popularization value.

This invention relates to the field of rail vehicle technology, providing a train bogie and a rail vehicle. The train bogie includes a frame and a wheel drive system. The frame includes a load-bearing body and two leaf springs. A center pin channel is formed in the middle of the load-bearing body, and two mounting channels are formed along the longitudinal direction of the frame. The two leaf springs are respectively mounted in the two mounting channels. The wheel drive system includes a shaft core, a bushing, and two wheels. The shaft core is rotatably mounted inside the bushing. A gearbox is constructed on the bushing, and a driving gear is provided inside the gearbox. A driven gear is sleeved on the shaft core, and the driving gear and the driven gear mesh externally. The two wheels are respectively mounted on both ends of the bushing via bearings, and the two wheels are respectively connected to both ends of the shaft core via flexible plates. Each leaf spring has a pad at both ends, and the pad is connected to the bushing. The load-bearing body and leaf springs replace the original crossbeam and side beam structure, resulting in a significant weight reduction effect on the frame.

The fireproof door for the prefabricated cabin comprises a door frame and a fireproof door body, the fireproof door body is contained in the door frame, and one side of the fireproof door body is hinged to the door frame; the fireproof door main body comprises a keel frame, a rock wool composite plate and an aluminum alloy plate; a cavity is formed in the keel frame, the cavity of the keel frame is filled with the rock wool composite board, and the outer side of the keel frame and the outer side of the rock wool composite board are wrapped with the aluminum alloy board. The fireproof door for the prefabricated cabin is light, and manual opening and closing are labor-saving.
