Abstract

An electric bed includes: a bed body, a plurality of bed planks, a wake-up device, a clock and a main control box. The main control box is electrically connected to the wake-up device and the clock, and is applicable for storing a wake-up time. The electric bed further includes a monitoring module. The monitoring module includes a processing module and a sensor, wherein the sensor is electrically connected to the processing module, and is applicable for monitoring whether a user has left the bed; if the sensor monitors that the user has not left the bed, the processing module activates the wake-up device when the wake-up time on the clock is due according to the stored wake-up time; and if the sensor monitors that the user has left the bed, the processing module does not activate the wake-up device when the wake-up time on the clock is due.

Claims

1. An electric bed, comprising a bed body, a plurality of bed planks, a wake-up device, a clock and a main control box, the main control box being electrically connected to the wake-up device and the clock and adapted to store a wake-up time, wherein the electric bed further comprises a monitoring module comprising a processing module and a sensor, wherein:

the sensor is electrically connected to the processing module, and is adapted to monitor whether a user has left the bed;

if the sensor monitors the user has not left the bed, the processing module activates the wake-up device when the wake-up time on the clock is due according to the stored wake-up time; and

if the sensor monitors that the user has left the bed, the processing module does not activate the wake-up device when the wake-up time on the clock is due;

wherein the monitoring module monitors large body movements occurring in a transition of light sleep and wakefulness processes and sends physical parameters of the user to the main control box in real time during a set wake-up time period; and

the main control box starts a preset wake-up mode when the user is about to wake up according to a predetermined program;

wherein the plurality of bed planks comprises at least a head bed plank, a waist bed plank, a leg bed plank and a foot bed plank hinged to each other by hinges;

the wake-up device comprises drivers respectively provided below the head bed plank and the foot bed plank for driving the head bed plank and the foot bed plank to rotate and linkage mechanisms for respectively working with the drivers;

when the head bed plank and the foot bed plank are rotated by respective drivers, respective linkage mechanisms of the head bed plank and the foot bed plank guide the head bed plank and the foot bed plank in predetermined strokes, and support the head bed plank and the foot bed plank after the head bed plank and the foot bed plank are moved into position.

2. The electric bed according to claim 1, wherein the sensor is a thin film pressure sensor provided on the plurality of bed planks.

3. The electric bed according to claim 2, wherein the wake-up device is a driver for driving one of the plurality of bed planks to rotate, one end of the driver is hinged to the bed body, and another end of the driver is hinged to a bed plank to be driven, and when the driver is activated by the main control box, the driver drives the bed plank hinged thereto to rotate.

4. The electric bed according to claim 2, wherein the wake-up device is a vibration massager, and the vibration massager is provided to at least one of the plurality of bed planks.

5. The electric bed according to claim 2, wherein the wake-up device is a sounding device provided in the bed body.

6. The electric bed according to claim 2, wherein the wake-up device is a light-emitting device provided in the bed body.

7. The electric bed according to claim 2, wherein the wake-up device further comprises at least one or more selected from the group consisting of a vibration massager provided to at least one of the plurality of bed planks, a sounding device and a light-emitting device, and wherein the main control box is further adapted to store a wake-up mode and select a required wake-up device according to a stored wake-up mode.

8. The electric bed according to claim 1, wherein the electric bed further comprises a wireless communication module, the wireless communication module is electrically connected to the main control box, and the wireless communication module is wirelessly connected to an intelligent terminal, the intelligent terminal sets and transmits a wake-up time and a wake-up mode to the wireless communication module by a user, and the wireless communication module receives and transmits the wake-up time and the wake-up mode to the main control box.

9. The electric bed according to claim 8, wherein the monitoring module is wiredly connected with the wireless communication module and communicating with each other in both directions, and the wireless communication module is wiredly connected with the main control box and adopts serial communication.
