Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and more particularly to an auxiliary baby-carrying device that relieves back muscle tension, as well as a method of operating this auxiliary baby-carrying device. Background Technology

[0002] In modern society, especially in the first year or two after a baby's birth, the frequent picking up and putting down of infants puts enormous physical strain on parents and grandparents. This is particularly true when holding an infant for extended periods, which puts significant strain on the muscles of the lower back, arms, and back. Currently, women and the elderly make up a large proportion of the primary caregivers in society, and their physical capacity is often more limited. Prolonged use of existing infant support equipment can easily lead to chronic injuries.

[0003] Although various assistive tools are available on the market (such as baby carriers, hip seats, and backpack-style baby bags), while their designs free up the hands to some extent, they fail to fundamentally solve the problem of concentrated stress on the lower back. Users still need to rely on their trunk muscles to support the baby's weight, leading to fatigue, pain, and even triggering conditions such as lumbar disc herniation.

[0004] Currently, common baby-carrying aids on the market have the following shortcomings: 1. Inadequate center of gravity design: Most devices still concentrate the baby's weight on the waist or shoulders, failing to make full use of the thighs' weight-bearing advantage.

[0005] 2. Poor stability under dynamic conditions: During walking or activity, existing equipment is prone to causing excessive shaking of the baby, resulting in insufficient comfort and safety.

[0006] 3. Rigid structure and lack of intelligent adjustment capabilities: Common products cannot automatically adjust according to changes in human posture, especially lacking an effective mechanism during the shift of the center of gravity from side to side, which can easily lead to tilting and discomfort.

[0007] 4. The overall burden has not been fundamentally reduced: Although the equipment can share some of the force, the waist and upper limbs still need to exert force for a long time, which can easily cause fatigue and injury with long-term use.

[0008] Therefore, it is necessary to develop a new type of baby-carrying assistive device based on human movement mechanisms and that fully relieves the burden on the waist muscles, in order to meet the multi-scenario childcare needs of modern families. Summary of the Invention

[0009] To overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an auxiliary baby-carrying device that relieves the waist muscles, which has a scientific structure and can automatically adjust the posture balance.

[0010] The technical solution of the present invention is: this auxiliary baby-carrying device that relieves waist muscles includes: a main body, a baby carrier (1), a support rod, a tension adjustment system, a sensor system, and a central control unit (2). The baby carrier is attached to the main body and holds the baby. It is made of soft and safe fabric and has a reinforced back panel and soft padding. The support rods, including a left support rod (31) and a right support rod (32), are fixed to the outer sides of the user's left and right thigh roots, and the support rods support the baby carrier; The tension adjustment system includes a retractable tension cord (41) and an electric motor (42). A retractable tension cord is set on each side of the baby carrier and connected to the left support rod and the right support rod respectively. The retraction and extension are controlled by the electric motor. The sensor system includes several non-contact distance sensors (5) distributed on the user's waist and thighs. The non-contact distance sensors monitor the relative distance changes between the user's sides and the baby carrier. The central control unit is located in the middle of the main body. It receives sensor data in real time and controls the tension of the retractable tension cord to ensure that the baby carrier remains in a balanced state.

[0011] The present invention has the following technical effects: 1. Significantly reduces the burden on the user's waist and arms, allowing for longer holding time and improved care efficiency.

[0012] 2. The combination of a stable support structure and automatic balance control significantly improves the comfort and safety of infants.

[0013] 3. Improve the intelligence and adaptability of the equipment, and automatically optimize according to body posture without the need for user intervention.

[0014] 4. Reduce the computational burden on transmission components and central control, thereby lowering product failure rates and maintenance costs.

[0015] 5. Enhance social confidence in childcare, improve the experience of infant and toddler care, and indirectly promote families' willingness to have children.

[0016] The method of using this baby-carrying aid that relieves back muscle tension is also provided, which includes the following steps: (1) The user wears an auxiliary baby-carrying device that relieves the waist muscles and places the baby in the baby carrier; (2) When the user takes a step, lifting one leg causes a lateral tilt; (3) The non-contact distance sensor captures the distance changes on the left and right sides; (4) The central control unit analyzes which side is closer to the body, determines the uneven support, and calculates the amount of adjustment needed; (5) The central control unit starts the electric motor and fine-tunes the length of the pull rope on the opposite side. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the structure of the baby-carrying aid device for relieving back muscle strain according to the present invention. Detailed Implementation

[0018] Through in-depth analysis of human anatomy, the applicant discovered that the groin area is one of the most weight-bearing parts of the human body, easily supporting multiple times the user's weight during daily walking and standing. If the fulcrum of an infant's weight could be shifted from the waist to the thighs, supplemented by an intelligent adjustment mechanism for postural balance, it would not only effectively reduce user fatigue but also significantly improve childcare comfort and safety.

[0019] like Figure 1 As shown, this baby-carrying aid that relieves back muscle strain includes: a main body, a baby carrier 1, a support rod, a tension adjustment system, a sensor system, and a central control unit 2; the arrows indicate the direction of the human body. The baby carrier is attached to the main body and holds the baby. It is made of soft and safe fabric and has a reinforced back panel and soft padding. The support rods, including a left support rod 31 and a right support rod 32, are respectively fixed to the outer sides of the user's left and right thigh roots, and the support rods support the baby carrier. The tension adjustment system includes a retractable tension cord 41 and an electric motor 42. A retractable tension cord is set on each side of the baby carrier and connected to the left support rod and the right support rod respectively. The retraction and extension are controlled by the electric motor. The sensor system includes several non-contact distance sensors 5, distributed around the user's waist and thighs. The non-contact distance sensors monitor changes in the relative distance between the user's sides and the baby carrier. The central control unit is located in the middle of the main body. It receives sensor data in real time and controls the tension of the retractable tension cord to ensure that the baby carrier remains in a balanced state.

[0020] The present invention has the following technical effects: 1. Significantly reduces the burden on the user's waist and arms, allowing for longer holding time and improved care efficiency.

[0021] 2. The combination of a stable support structure and automatic balance control significantly improves the comfort and safety of infants.

[0022] 3. Improve the intelligence and adaptability of the equipment, and automatically optimize according to body posture without the need for user intervention.

[0023] 4. Reduce the computational burden on transmission components and central control, thereby lowering product failure rates and maintenance costs.

[0024] 5. Enhance social confidence in childcare, improve the experience of infant and toddler care, and indirectly promote families' willingness to have children.

[0025] Preferably, the baby carrier is provided with a crossbar 11, which is horizontally positioned at the bottom of the baby carrier. A non-contact distance sensor 5 is provided at the center of the crossbar, and a retractable tension cord is provided at each end of the crossbar.

[0026] Preferably, the bottom of the baby carrier is provided with a supporting tripod 6.

[0027] Preferably, the support rod is fitted with a spring.

[0028] Preferably, the device further includes a second support rod, which includes a left second support rod 71 and a right second support rod 72, respectively fixed below the user's left and right thigh roots.

[0029] When a user takes a step, one leg naturally lifts up and loses its ability to support the ground, while the other leg remains upright and can bear weight. This device cleverly utilizes this physiological characteristic of the human body, eliminating the need for a "left and right support bar switching" method. Instead, it allows the support bar on the side of the stepping leg to passively detach from the weight-bearing state, with the baby supported solely by the other leg.

[0030] This process requires no intervention from a central controller and relies on the natural movement of the human body to complete the "support conversion," significantly reducing the complexity of the control logic.

[0031] The method of using this baby-carrying aid that relieves back muscle tension is also provided, which includes the following steps: (1) The user wears an auxiliary baby-carrying device that relieves the waist muscles and places the baby in the baby carrier; (2) When the user takes a step, lifting one leg causes a lateral tilt; (3) The non-contact distance sensor captures the distance changes on the left and right sides; (4) The central control unit analyzes which side is closer to the body, determines the uneven support, and calculates the amount of adjustment needed; (5) The central control unit starts the electric motor and fine-tunes the length of the pull rope on the opposite side.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
