The invention relates to a linear motor for a sliding door, comprising a mover assembly, a stator assembly and a controller for controlling the mover assembly to move, the stator assembly is electrically connected with the controller, and comprises two or more stators; the controller is arranged between the two adjacent stators; and end parts of the stators on two sides of the controller are provided with Hall devices. The mover assembly can move on a left side and a right side of the controller, and the moving range is increased. Furthermore, the Hall devices are arranged at the end parts of the stators on the two sides of the controller, the moving range of the mover assembly to the left side and the right side can be further increased, so that the system can adapt to a wider door opening without changing the length of the stator assembly.

One or more embodiments of an automatic switching device and a refrigeration device is provided. The automatic switching device includes an ejection structure including a transmission gear and a rack matching the transmission gear in transmission. The automatic switching device includes a driving device, connected to the transmission gear and used for driving the transmission gear to rotate, so as to drive the rack to extend forwards to open a door body or retract backwards to close the door body. The automatic switching device further includes an auxiliary control device including an inductor arranged on the rack, a first induction switch and a second induction switch.

The present disclosure provides an automatic switching device and a refrigeration device. The automatic switching device comprises: an ejection structure, comprising a transmission gear and a rack matching the transmission gear in transmission; a driving device, connected to the transmission gear and used for driving the transmission gear to rotate, so as to drive the rack to extend forwards to open a door body or retract backwards to close the door body; and an auxiliary control device comprising an inductor arranged on the rack, a first induction switch and a second induction switch.

A driving device for electric sliding doors has: a track, a driving unit, a gliding member, and a door panel. The track has a first groove and a second groove, the driving unit is mounted on the first of the track Inside the groove and has a circuit board and two electromagnet sets connected to both sides of the circuit board. The gliding member is disposed in the second groove, and the gliding member is arranged in the order facing the driving unit, and the door panel is fixed to the bottom of the gliding member by the track. The electric door system of the present invention controls the magnetic pole change of the electromagnet sets through the circuit board, and utilizes the characteristics of the magnetic poles to move the magnetic member of the gliding member, such that the mechanical mechanism of the electric door can have silent operation.

The present invention relates to a body, in particular a cabinet, with a part that can be pivoted between two positions by an electric motor, for example a door or panel. During its closing movement, the body, in particular the cabinet, actuates a control device that activates the motor. A separate sensor, which reacts to the movements of the control device and by means of which the motor output can be changed, is arranged between the control device and the motor.
