The invention discloses a shifting and gliding mechanism for a carbonless trolley up and downhill, which includes a power transmission assembly and an electric control assembly; the power transmission assembly includes a rear driving wheel half shaft, a rear driven wheel half shaft and a tapered bush The winding shaft and the rear driving wheel semi-shaft are connected with an axially movable inner and outer spline sleeve through a spline, and the sleeve and the winding shaft are connected by two pairs of constant mesh gears; the electric control component includes a single-chip microcomputer and is electrically connected to the single-chip microcomputer Infrared pair tube, wheel speed sensor and two DC electromagnets that can shift the constant mesh gear; when going up and downhill, the single-chip microcomputer sends different commands to control different DC gears according to the electrical signals sent by the infrared pair tube and grating wheel speed sensor The power on and off of the type electromagnet makes the power transmission route switch between two pairs of constant mesh gear pairs, and completes the gear conversion between the flat road and the ramp. The invention has the advantages of being able to carry out intelligent detection, accurately changing the driving force, saving gravitational potential energy and making the traveling speed of the trolley uniform, and the like.

The invention provides a sponge grinding block production line. The sponge grinding block production line comprises an uncoiling device, a surface treatment device, a sand embedding device, a drying device and a sponge combination device which are sequentially arranged in the thin film operation direction. The invention further provides a sponge grinding block production method. The method adopts the above devices and includes the following steps of uncoiling, surface treatment, static sand embedding, drying and sponge combination. Continuous and automatic machining can be sequentially finished on the same production line, the occupied space is small, a specially-assigned person on duty is not needed in all the processes, therefore, the labor force is saved, the labor intensity is relieved, and the production efficiency is improved; a thin film is subjected to surface treatment through the production method, the surface of the thin film is rough, the adsorption capacity can be improved, and gluing is more uniform; and by means of a metal layer electroplated on the surface of the thin film, the strength of the thin film is improved, gluing and sand embedding are facilitated, and the product quality is further guaranteed.

The invention discloses a double-layer battery trailer for new energy vehicles and relates to the technical field of battery trailers. The invention includes a box body, a conveying platform, an electric screw device, a transmission device and a battery cover plate; the battery cover plate and the electric screw screw device are threaded and rotated; the battery cover plate is slidably matched with the box body; the transmission device and the battery cover plate are meshed for transmission Cooperate. In the present invention, the bracket is designed as a frame structure, which saves materials and reduces its own weight; through the meshing transmission of the rotating gear and the rack, the faulty battery is transferred to the intermediate transfer platform, and the faulty battery is transferred to the box through the conveying platform At the bottom, the gravitational potential energy of the faulty battery is reduced to ensure the stability of the entire device; the spare battery is lifted by the electric screw device; the purpose of quickly replacing the new energy battery is realized, and it is guaranteed that people can replace the spare battery independently in case of emergency , which brings convenience to people's travel.
