Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to a device for reminding and automatically rescuing passengers in an elevator car who have forgotten to call the elevator. Background Art

[0002] Elevators have gradually become an important means of transportation that everyone needs to take when entering and exiting buildings. However, sometimes a passenger forgets to press the desired floor button after entering the elevator due to other things. After the elevator door closes automatically, the passenger thinks the elevator is running, but in fact the elevator enters energy-saving mode at this time.

[0003] Some elevators currently have an energy-saving function, that is, about 2 minutes after the elevator door is closed, if the elevator has no internal call or external call signal, the elevator will automatically turn off the elevator car lighting. At this time, passengers may mistakenly believe that the elevator is malfunctioning, and then notify the property or elevator maintenance personnel to resolve the problem, resulting in unnecessary waste of manpower. Utility Model Content

[0004] The utility model aims to provide a device for reminding and automatically rescuing passengers in an elevator car when they forget to call the elevator, so as to solve the problem of being trapped in an elevator with an energy-saving function because passengers forget to press the desired floor button.

[0005] To achieve the above-mentioned object, the present invention provides a device for reminding and automatically rescuing passengers in an elevator car who forget to call the elevator. The device comprises an elevator car body, an elevator energy-saving relay JN, a human body sensing switch RTJ, and a time-delay disconnection relay DSQ. The human body sensing switch RTJ is installed on the top of the elevator car body, and a data collection end of the human body sensing switch RTJ is located inside the elevator car body. The elevator car body is provided with a car door, and an operating panel and a voice prompter are also installed inside the elevator car body.

[0006] The elevator energy-saving relay JN and the time-delay disconnection relay DSQ are provided in the control system of the elevator car body, and the elevator energy-saving relay JN and the time-delay disconnection relay DSQ are both electrically connected to the human body sensing switch RTJ.

[0007] Wherein, a mounting hole is provided at the top of the elevator car body, a mounting assembly is provided at the mounting hole, and the human body sensing switch RTJ is installed at the top of the elevator car body through the mounting assembly.

[0008] Wherein, the mounting assembly includes a mounting tube, a mounting ring and a top cover plate, the top cover plate is installed at the mounting hole, the edge of the top cover plate covers the outside of the mounting hole, the bottom of the top cover plate is embedded in the inside of the mounting hole, the mounting tube is detachably connected to the top cover plate, and is located at the bottom of the top cover plate and inside the mounting hole, the mounting ring is provided at one end of the mounting tube away from the top cover plate, the human body sensing switch RTJ is installed on the mounting ring, and the electrical connection end of the human body sensing switch RTJ is located inside the mounting tube and extends to the outside of the top end of the elevator car body.

[0009] Wherein, an embedding protrusion is fixedly provided on the bottom of the top cover plate, the embedding protrusion is embedded in the interior of the mounting hole, and the mounting tube is detachably connected to the embedding protrusion.

[0010] Wherein, a first thread is provided on the inner bottom wall of the embedded protrusion, and a second thread is provided on the outer side wall of the mounting tube away from the mounting ring, and the first thread is adapted to the second thread.

[0011] The utility model discloses a device for reminding and automatically rescuing passengers in an elevator car when they forget to call for the elevator. The device comprises an elevator car body, an elevator energy-saving relay JN, a human body sensing switch RTJ and a time-delayed disconnection relay DSQ. When the car door is closed and the elevator car body does not receive an operation instruction within 2 minutes, the elevator energy-saving relay JN is activated. At this time, if the human body sensing switch RTJ detects that there is a passenger in the elevator car body, the normally open contact of the elevator energy-saving relay JN is connected in series with the switch signal of the human body sensing switch RTJ to trigger the action of the time-delayed disconnection relay DSQ. The normally open contact of the delayed disconnection relay DSQ sends an opening signal to the car door to automatically open the car door and simultaneously triggers the voice prompter to prompt the passenger to leave the elevator car body or select the floor button to be reached by the control panel, thereby realizing the reminder and automatic rescue function when the passenger forgets to press the floor button to be reached and is trapped.
