Furthermore, the cradle further comprises a spring stretching module, and the spring stretching module is connected with the sliding block of the cam connecting rod module to ensure the stability of transmission.

Still further, the cam connecting rod module comprises a cam, a snap nail, a connecting rod, a sliding block and a printing sliding block, the sliding block is driven to move up and down by the rotation of the cam, the sliding block drives the connecting rod to move, the snap nail connects the two connecting rods, and finally the bed body on the top is driven to swing.

The spring stretching module comprises an aluminum profile rack, a spring and a cam, the module is used for connecting the sliding block with the rack, the connecting rod is prevented from being separated from the cam, the possibility of meshing disconnection is avoided, the module plays a role when the gravity center of the shaking table is lifted and passes over the center, and the mechanism is pulled back to the positive rail.

The electronic control module is used for controlling the rotating speed of the two control motors through programming of the single chip microcomputer, and is connected with the control ends of the control motors. The adjustment of various modes is realized by controlling the rotating speed of the motor.

The vibration module comprises a vibration sensor, and the vibration sensor is attached to the side edge of the shaking table. When the baby is awake, the vibration sensor receives vibrations, output signal, and the motor just can open, and the shaking table just can continue to rock. When the baby falls asleep, the vibration sensor does not sense the vibration, a signal is output, and the shaking is stopped. The baby wakes up and starts shaking again.

The beneficial effects of the utility model are that: three shaking curves are respectively designed for infants in different periods so as to meet different requirements, and meanwhile, the shaking module is additionally arranged to automatically start shaking when the infants are awakened so as to achieve the purposes of automatically soothing the sleeping infants and reducing the burden of parents.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, a multifunctional cradle comprises a bed body, a cam link module, a spring stretching module, an electronic control module and a vibration module, wherein the middle part of the bed body is mounted on a frame through a universal shaft, two sides of the bottom of the bed body are respectively connected with an action end of the cam link module, the cam link module is connected with a control motor, the control motor is mounted on the frame, and the electronic control module controls the rotation of the motor to output different shaking modes; the vibration module is arranged on the bed body and used for judging the state of the child and giving out a control signal.

Furthermore, the cam connecting rod module comprises a cam 8, a snap nail 3, a connecting rod 2, a sliding block 6 and a printing sliding block 7, the sliding block 6 is driven to move up and down by the rotation of the cam, the sliding block 6 drives the connecting rod 2 to move, the snap nail 3 connects the two connecting rods, and finally the bed body 1 on the top is driven to swing; through the careful design of the cam profile, the motion of the cradle is accurately controlled through the connecting rod, and the cradle can also swing left and right when the two ends of the cradle rise and fall by simultaneously using the cam connecting rod mechanism to the front side surface, so that the curvilinear motion of the cradle for the comfortable sleep of the baby is better realized.

The spring stretching module comprises an aluminum profile rack 5, a spring 1 and a cam 8, the module is used for connecting the sliding block with the rack, the connecting rod is prevented from being separated from the cam, the possibility of meshing disconnection is avoided, the module plays a role when the gravity center of the shaking table is over the center, and the mechanism is pulled back to the positive rail.

The electronic control module controls the signal output of the motor driving module through programming of the single chip microcomputer, so that the effect of controlling the rotating speed of the motor is achieved, and adjustment of various modes is achieved.

The vibrations module includes vibration sensor, and vibration sensor pastes in the shaking table side, and when the baby was awake, vibration sensor received vibrations, and output signal, the motor just can be opened, and the shaking table just can continue to rock. When the baby falls asleep, the vibration sensor does not sense the vibration, a signal is output, and the shaking is stopped. The baby wakes up and starts shaking again.

In this embodiment, the control motor drives the cam link module to regularly swing the cradle above the cradle, and the cradle includes the cam link module, the spring stretching module, the electronic control module and the vibration module, the cam is driven by the motor 14 to rotate the shaft 13, the spring 11 is connected to the frame to ensure the connection between the cam and the slider, and the motor drives the cam to rotate, so that the cam link module can operate to finally drive the basin at the top. 2. 3, a connecting rod mechanism is formed, 5 aluminum profiles are used as a bottom support of the device, 10 universal wheels are installed on the aluminum profiles, the device can move freely, 9 corner connectors tightly connect the bottom aluminum profiles with the sliding rails, 12 and 13 bearing seats and shafts are used for connecting motors to drive the cams to rotate, motor connecting pieces are used for fixing the motors, and 18, 19, 20, 21, 22 and 23 are used for supporting and guaranteeing the top shaking table 1 to shake freely. Firstly, a corresponding gear is selected according to the age of the baby, after the baby bed vibration module senses vibration, the vibration mode is started, and the square motor and the side motor are controlled to rotate according to the required rotating speed according to a program preset by the single chip microcomputer. The motor transmits the rotation to the cam through the coupler, the cam pushes the sliding block, the sliding block is hinged with the connecting rod, and the connecting rod is fixed with a bed working point. And the target motion curve is realized by controlling the shaking table through the input of a square side motor. When the baby falls asleep gradually, the vibration is reduced, the vibration module outputs a signal to control the motor to stop rotating. When the baby is awakened suddenly, the shaking table shakes, the shaking module receives the shaking signal again, the motor is started again, and the shaking mode is started until the baby is comfortable to sleep.
