Document Type and Number:
WIPO Patent Application WO/2018/113093
Kind Code:
A1
Abstract:
Disclosed are an automatic switching device (10) and a refrigeration device (1). The automatic switching device (10) comprises: an ejection structure (102), the ejection structure (102) comprising a transmission gear (1022) and a rack (1024) matching the transmission gear (1022) in transmission; a driving device (104), connected to the transmission gear (1022) and used for driving the transmission gear (1022) to rotate, so as to drive the rack (1024) to extend forward to open a door body (30) or retract backwards to close the door body (30); and an auxiliary control device (106) comprising an inductor (1062) arranged on the rack (1024), a first induction switch (1064) and a second induction switch (1066); when the inductor (1062) moves to the position of the first induction switch (1064), by generating a first control signal, the first induction switch (1064) controls the driving device (104) to stop working so as to cause the door body (30) to be in an opened state; and when the inductor (1062) moves to the position of the second induction switch (1066), by generating a second control signal, the second induction switch (1066) controls the driving device (104) to stop working so as to cause the door body (30) to reset to a closed state. According to the technical solution, after the door body (30) is opened, maintenance by external force is not needed, and the stroke is controllable.
