Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of baby rocker support frames, and more specifically, to a baby rocker support frame with horizontal lifting function. Background Technology
[0002] The baby rocker support frame is a key component of a baby rocker, providing overall structural support and enabling the rocking and lifting functions. The frame is typically made of robust materials to ensure it can safely support the baby's weight while maintaining sufficient stability and durability. This frame controls the rocker's movement, including horizontal rocking and vertical lifting, through integrated drive mechanisms such as motors and transmission systems, providing comfort and soothing for the baby. Furthermore, the design of the baby rocker support frame must consider ease of operation, flexibility of adjustment, and baby safety to adapt to the needs of different babies and enhance the care experience.
[0003] Existing baby rockers lack effective shock absorption and noise reduction measures during raising and lowering, which can potentially affect an infant's hearing and disrupt their sleep and rest. Furthermore, the inflexible adjustment mechanisms make it difficult to precisely adjust to an infant's weight and preferences, failing to provide personalized comfort and impacting the user experience. In addition, the lack of effective locking mechanisms in traditional designs creates safety hazards during raising and lowering, increasing the risk of accidental falls and threatening the infant's safety.

Simultaneously, a lifting motor is fixed to a fixed base 301 via a motor shock absorber. Its drive end rotates a small transmission wheel, which in turn rotates a large transmission wheel via a lifting transmission belt. This rotational motion is transmitted to an eccentric shaft via a reduction gearbox, causing the eccentric shaft to drive a bearing and a lifting slider to slide back and forth along a rail on a lifting sliding support, generating lifting reciprocating motion and driving a parallelogram-like lifting mechanism to produce lifting reciprocating motion. The advantage of this design is that, through two independent motors and transmission systems, the baby rocker can achieve independent horizontal and vertical movement, providing a more comfortable and natural rocking experience for the baby. At the same time, the shock absorber design effectively reduces noise and vibration, protecting the baby's hearing and comfort. This invention utilizes a lifting actuator where the upper and lower halves of a connecting rod are connected by a central hinge shaft. The top of the upper half of the connecting rod is connected to the lifting seat via an upper hinge shaft, and the bottom of the lower half is connected to the lifting slider via a lower hinge shaft. When the lifting slider moves left and right along the slide rail under the drive of the lifting reciprocating drive device, it drives the lifting push plate and connecting rod to move synchronously, thereby pushing the lifting seat up or down to achieve lifting motion. An assist spring is placed between the lifting slider and the fixed base 301 to provide auxiliary force for the lifting motion, reduce the motor load, and improve energy efficiency. The advantage of this design is that, through the ingenious connection of the lifting actuator, horizontal reciprocating motion and lifting reciprocating motion are effectively combined, allowing the baby rocker to simulate a more natural rocking motion, which helps soothe and promote sleep in infants.

Detailed Implementation
[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example
[0017] A preferred embodiment of the baby rocker support frame with horizontal lifting function provided by this utility model is, for example... Figures 1 to 4 The system includes: a fixed base assembly 1, comprising a fixed base 101, a horizontal sliding support rod 102, and a horizontal gearbox mounting base 103. The horizontal sliding support rod 102 is movably mounted on the fixed base 101 and the horizontal gearbox mounting base 103. A horizontal reciprocating drive device 2 is mounted on the horizontal gearbox mounting base 103 and is used to output horizontal reciprocating motion. A lifting sliding support rod 409 is mounted on the horizontal reciprocating drive device 2. A lifting reciprocating drive device 3 is mounted on the lifting sliding support rod 409 and is used to output lifting reciprocating motion. The lifting reciprocating drive device 3 includes a fixed base 310 and a lifting actuator 4 mounted on the lifting sliding support rod 409, which converts the horizontal reciprocating motion into lifting motion.
[0018] In this embodiment, the horizontal reciprocating drive device 2 includes: a horizontal motor 201 mounted on a horizontal gearbox mounting base 103, a motor shock absorber 202 fixedly mounted on the horizontal gearbox mounting base 103, the horizontal motor 201 fixedly mounted inside the motor shock absorber 202, a small transmission wheel 203 fixedly mounted on the drive end of the horizontal motor 201, a horizontal transmission belt 204 mounted on the outer surface of the small transmission wheel 203, and a large transmission wheel 205 sleeved on one end of the horizontal transmission belt 204.
[0019] In this embodiment, the horizontal reciprocating drive device 2 further includes: a reduction gearbox 206 fixedly installed on the horizontal gearbox mounting base 103, the drive end of the reduction gearbox 206 being fixedly connected to the large transmission wheel 205, another drive shaft of the reduction gearbox 206 being fixedly installed with an eccentric shaft 207, a bearing 208 being fixedly installed on the eccentric shaft 207, a horizontal slide block 209 being fixedly installed on the bearing 208, and the horizontal slide block 209 being movably sleeved on the horizontal slide rail provided on the horizontal sliding support rod 102.
[0020] In this embodiment, the lifting reciprocating drive device 3 includes: a lifting motor 301 fixedly installed on a fixed base 310; a motor shock absorber 302 fixedly sleeved on the outer surface of the lifting motor 301; the motor shock absorber 302 fixedly installed on the fixed base 310; a small transmission wheel 303 fixedly installed at the drive end of the lifting motor 301; a lifting transmission belt 304 on the outer surface of the small transmission wheel 303; and a large transmission wheel 305 sleeved at one end of the lifting transmission belt 304.

Its drive end drives the small transmission wheel 203 to rotate, which in turn drives the large transmission wheel 205 to rotate via the horizontal transmission belt 204. This rotational motion is transmitted to the eccentric shaft 207 via the reduction gearbox 206, causing the eccentric shaft 207 to drive the bearing 208 and the horizontal slide block 209 to slide back and forth along the horizontal slide rail on the horizontal sliding support rod 102, generating horizontal reciprocating motion. At the same time, the lifting motor 301 is fixed to the fixed base 310 via the motor shock absorber 302. Its drive end drives the small transmission wheel 303 to rotate, which in turn drives the large transmission wheel 305 to rotate via the lifting transmission belt 304. This rotational motion is transmitted to the eccentric shaft 307 via the gearbox 306, causing the eccentric shaft 307 to drive the bearing 308 and the lifting slider 309 to slide back and forth on the slide rail fixedly mounted on the lifting sliding support rod of the fixed base 310. This drives the parallelogram-like lifting mechanism to produce a lifting and reciprocating motion. The advantage of this design is that, through two independent motors and transmission systems, the baby rocker can achieve independent horizontal and vertical movement, providing the baby with a more comfortable and natural rocking experience. At the same time, the shock-absorbing seat design effectively reduces noise and vibration, protecting the baby's hearing and comfort. Example

The lifting slider 309 is fixed on the lifting sliding support rod 409. When the lifting slider 309 moves left and right along the slide rail under the drive of the lifting reciprocating drive device 3, it drives the lifting push plate 403 and the upper half of the connecting rod 401 to move synchronously, thereby pushing the lifting seat 408 to rise or fall, thus realizing the lifting motion. The assist spring 410 is set between the lifting slider 309 and the fixed base 310 to provide auxiliary force for the lifting motion, reduce the motor load, and improve energy efficiency. The advantage of this design is that, through the ingenious connection of the lifting actuator 4, the horizontal reciprocating motion and the lifting reciprocating motion are effectively combined, allowing the baby rocker to simulate a more natural rocking motion, which helps to soothe and help the baby sleep.
