Description

Technical Field

[0001] This utility model belongs to the field of infant and toddler products technology, and in particular relates to an infant and toddler bionic sleep aid bed. Background Technology

[0002] Most electric infant cribs on the market currently use a single movement mode; the left-right rocking type only simulates horizontal swaying and lacks vertical movement; the up-down vibration type only provides vertical vibration and cannot reproduce the complex movement trajectory felt when held. This single movement mode is fundamentally different from the synchronous forward-backward and up-down movement felt by infants in human arms, resulting in poor adaptability and limited soothing effect for infants.

[0003] Traditional mechanical structures cannot reproduce synchronous forward and backward displacement and up and down movement; most products only support a fixed height and cannot adapt to the needs of multiple scenarios such as nursing tables and strollers; the guardrails cannot be opened or closed and the headboard cannot be removed, increasing the difficulty of picking up and taking out infants; ordinary motors and pulley mechanisms are noisy, affecting the sleep quality of infants and young children. Utility Model Content

[0004] This utility model provides a bionic sleep aid bed for infants and toddlers, the specific technical solution of which is as follows: A bionic sleep aid bed for infants and toddlers includes a bed frame, a detachable headboard, a lifting electric push rod, a reciprocating motor, an adjustable stroke cam, a linear optical axis, a silent linear guide rail, a silent linear guide rail slider, and medical silent casters; The bed is horizontally arranged to support infants and young children; The detachable headboard is detachably connected at both ends along the longitudinal direction of the bed frame to protect the head and feet of infants and young children; The fixed end of the lifting electric push rod is fixed to the bottom frame, and the telescopic end is hinged to the bed longitudinal beam. The lifting electric push rod is driven by a built-in motor. By extending and retracting the push rod vertically, the bed longitudinal beam is raised and lowered, thus changing the overall height. The reciprocating motor is fixed in the bottom frame, and its output shaft is connected to the active end of the cam linkage mechanism to provide reciprocating power in the forward and backward directions. Two silent linear guides are provided, which are symmetrical and obliquely arranged relative to the longitudinal center line of the bed. The silent linear guides are fixed to the bottom frame. One end of the silent linear guide slider is connected to the silent linear guide, and the other end is fixed to the longitudinal beam of the bed. It is used to convert the horizontal thrust of the cam linkage mechanism into the combined front-back and up-down displacement of the bed. The cam linkage mechanism consists of an adjustable stroke cam and a linear optical shaft. The adjustable stroke cam is keyed to the output shaft of the reciprocating motor. One end of the linear optical shaft is hinged to the adjustable stroke cam, and the other end is hinged to the bearing set on the longitudinal beam of the bed, so as to realize the adjustment of the front and rear vibration amplitude. The medical silent casters are provided in four units, each with a brake, and are fixed to the bottom surface of the bottom frame for overall movement and locking positioning; The bed is equipped with guardrails on both sides, which are hinged to the side beams and can be manually rotated downwards by 180° to facilitate the carrying and getting in and out of infants and young children.

[0005] In a preferred embodiment of the aforementioned bionic sleep aid bed for infants and toddlers, the oblique arrangement direction of the silent linear guide rail is coplanar with the thrust direction of the cam linkage mechanism.

[0006] In a preferred embodiment of the aforementioned bionic sleep aid bed for infants and toddlers, the lifting electric push rod and the reciprocating motor are controlled by a motor controller to achieve forward and backward reciprocating and up and down lifting movements. The electric linear actuator remote control communicates with the motor controller wirelessly or via wired connection, and is used to send start / stop, amplitude, speed, and timing commands to the motor controller.

[0007] The preferred embodiment of the aforementioned bionic sleep aid bed for infants and toddlers is that the upper surface of the bed frame is covered with a washable 3D breathable pad, which is connected to the soft-padded frame of the bed frame by zippers around the perimeter, forming a smooth transition when the zippers are closed.

[0008] The preferred embodiment of the aforementioned bionic sleep aid bed for infants and toddlers is that the bottom frame is spliced ​​from aluminum profiles, and there are horizontally adjustable feet at the four corners. The feet and medical silent casters support the ground simultaneously. When the brakes of the medical silent casters are released and the feet are unscrewed, the whole structure enters a fixed working mode.

[0009] The working principle of a bionic sleep aid bed for infants and toddlers: When in operation, the reciprocating motor receives a command from the motor controller and starts to drive the cam linkage mechanism to rotate; the wheel linkage mechanism converts the rotational motion of the motor into push-pull mechanical displacement; the inclined silent guide rail slider slides along the silent guide rail; through the inclined rail and cam dual-degree-of-freedom linkage system, the forward and backward displacement and up and down undulation of a human embrace are accurately simulated synchronously to achieve a bionic sleep-inducing effect.

[0010] Beneficial effects

[0011] This invention accurately simulates the front-to-back and up-to-down synchronization of human embrace, improving the efficiency of infants and young children falling asleep. This utility model has multiple functions, adjustable height, and is suitable for nursing tables, trolleys and other scenarios; the detachable headboard and guardrail make it easy to pick up and store; it uses medical silent casters to reduce noise and avoid sleep disturbance; the casters are locked to prevent movement, making it safer and more convenient.

[0012] This invention solves the biomimetic defects and functional shortcomings of traditional products, providing an efficient and reliable solution for infant sleep care. Attached Figure Description
