The utility model provides an electric hinge and an electric door and a steaming oven comprising the electric hinge, the electric hinge comprises a transmission assembly, the transmission assembly comprises a first connecting rod and a second connecting rod, the electric hinge further comprises a flexible connecting part, the first connecting rod and the second connecting rod are connected through the flexible connecting part, and the first connecting rod is connected with the second connecting rod through the flexible connecting part. The electric hinge further comprises a damping part, one end of the damping part is arranged on a support of the electric hinge, an output shaft of the damping part is hinged to the second connecting rod, and when the electric hinge is locked, the output shaft of the damping part provides resistance larger than reset elastic force of the electric hinge. And the resistance is smaller than the reset pulling force of the electric hinge. According to the electric hinge, the damping part is arranged and used for absorbing kinetic energy of the second connecting rod, so that the second connecting rod and the first connecting rod cannot directly abut against each other, and the situations of pause, collision and abnormal sound occurring in the door closing process of a door body connected with the electric hinge are reduced.

This invention discloses a multi-mode hierarchical control method, device, and storage medium for an electromechanical brake, belonging to the field of braking control technology. The method includes: determining the current braking mode, which includes: no-travel braking mode, clamping force following braking mode, and retraction mode; when in no-travel braking mode, using a zero-force servo control method for braking, and determining whether the friction pad and brake disc have reached the contact proximity point; if so, entering the clamping force following braking mode; when in clamping force following braking mode, using a dual-fuzzy adaptive sliding mode control method based on the EMB dynamics model to track the target clamping force to enable braking; when in retraction mode, identifying the retraction intention and releasing the brake. This invention can seamlessly switch between multiple control modes, accurately identify the critical contact state of braking, improve tracking accuracy and stability, and avoid dragging or jerking during retraction.

A concentric angle adjuster for a car seat and the car seat thereof belong to the technical field of car seat accessories. It includes an inner gear plate; a bushing with a central hole in the inner gear plate; a pair of wedge-shaped blocks disposed within the bushing cavity; a gear meshing with the inner gear plate, with a gear shaft head extending from the center of the left side of the gear, the inner walls of the pair of wedge-shaped blocks contacting the outer wall of the gear shaft head; a backrest moving plate located to the right of the gear; and a backrest moving plate control plate fixed to the right side of the inner gear plate. The key feature is that it also includes a cross-sliding coupling located between the gear and the opposing side of the backrest moving plate, with a set of cross-sliding coupling mating bosses formed on the right side of the gear, and a cross-sliding coupling receiving cavity formed on the left side of the backrest moving plate, the cross-sliding coupling being disposed within the cross-sliding coupling receiving cavity. Advantages: Improves the speed and ease of backrest angle adjustment, avoids problems such as jerking and noise during adjustment; isolates external dust and debris from intrusion.
