Description

Technical Field

[0001] This invention relates to the field of child safety seat technology, specifically to an anti-motion sickness and anti-milk spillage smart child safety seat and its usage method. Background Technology

[0002] Child safety seats are restraint devices specifically designed for children and installed in cars to improve their safety while traveling. According to research data from the World Health Organization (WHO), proper use of child restraint systems can reduce infant car fatalities by 71%. However, existing child safety seats still have many technical shortcomings in practical use:

[0003] Most existing child safety seats use a fixed foam filling structure or a mechanical adjustment structure, and their support configuration is determined at the factory.

[0004] During vehicle travel, children experience inertial displacement due to the vehicle's acceleration, deceleration, and turns. Infants and young children, with their underdeveloped vestibular systems, have poorer comfort and physiological adaptability during travel, making them prone to motion sickness. Studies show that the incidence of motion sickness in children under 12 years old is approximately 40%-50%, with the 2-12 age group being the most susceptible. Motion sickness reactions are more severe in this age group, often manifesting as irritability, crying, paleness, and vomiting, significantly impacting the travel experience.

[0005] Traditional static support structures cannot respond to these changes in real time. Studies have shown that children's bones are not fully developed, and prolonged exposure to uneven pressure distribution while sitting may lead to an imbalance of forces on both sides of the spine, potentially causing problems such as scoliosis.

[0006] Meanwhile, existing child safety seats primarily focus on the instantaneous impact in collisions, while paying insufficient attention to the continuous vertical vibrations caused by frequent bumpy road surfaces encountered during daily driving. Although some seats incorporate springs or foam layers in the base for cushioning, the cushioning direction is singular, providing only simple vertical compression cushioning. Furthermore, the foam layer is prone to horizontal slippage under pressure, causing misalignment between the foam and the child's body, reducing its support effectiveness. The elastic elements are mostly metal springs or ordinary rubber, which rebound quickly and cannot effectively absorb vibrational energy, potentially creating a "bouncing" effect that exacerbates discomfort such as motion sickness and spitting up in children.

[0007] Therefore, we propose a smart child safety seat that prevents motion sickness and milk spillage, along with its usage method. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent child safety seat that prevents motion sickness and milk spillage, and its usage method, in order to solve the problems that existing child safety seats generally adopt fixed foam filling structures or mechanical adjustment structures, which cannot adapt to changes in different vehicle movement states, and at the same time have insufficient cushioning performance on bumpy roads.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an intelligent child safety seat that prevents motion sickness and milk spillage, comprising a base that rests against the car seat, and an inner liner for a child to sit on connected to the upper part of the base via a support seat.

[0010] The inner liner includes a left wing area, a right wing area, a waist area and a head wing area. Each area is equipped with an array of air bags. Multiple sets of air bags are connected to corresponding micro solenoid valves through independent air channels. The independent air channels are connected to air pumps.

[0011] The base is equipped with a vehicle status detection unit. Based on the signal fed back by the vehicle status detection unit, the air pump uses a miniature solenoid valve to independently inflate and deflate the air bags in each area, thereby adjusting the pressure distribution on the various support parts of the child's body.

[0012] Preferably, the vehicle status detection unit includes a gyroscope sensor, which is installed inside the base and is used to detect vehicle acceleration, tilt angle and vibration frequency.

[0013] The air pump is electrically connected to the control unit, which drives the corresponding miniature solenoid valve to perform the inflation and deflation actions based on the detection signal from the gyroscope sensor.

[0014] Preferably, the air bags in each area of ​​the inner liner are arranged in an array, and adjacent air bags are connected by an elastic diaphragm so that the air bags maintain a close fit to the child's body surface during inflation and deflation.

[0015] Preferably, a pressure-reducing and shock-absorbing component is provided between the inner liner and the base, the pressure-reducing and shock-absorbing component comprising:

[0016] The seat cushion foam layer is located inside the inner lining and comes into contact with the child's seat surface.

[0017] A support frame is disposed below the foam layer of the seat cushion and connected to the base;

[0018] An elastic support is provided between the cushion foam layer and the support frame. The elastic support is composed of multiple sets of interwoven elastic ropes, which are connected to the four sides of the inner wall of the support frame by hooks, so that the cushion foam layer forms an elastic pressure-bearing structure on the support frame through the elastic support net.

[0019] Preferably, the support frame is provided with limiting wings on both sides, and the cushion foam layer is provided with guide protrusions on both sides that cooperate with the limiting wings. The limiting wings and the guide protrusions form a sliding pair to restrict the up and down movement of the cushion foam layer and prevent the cushion foam layer from coming off in the horizontal direction.

[0020] Preferably, an environmental adjustment component is provided in the contact area between the base and the inner liner, the environmental adjustment component comprising:

[0021] The module box is embedded in the base;

[0022] An air supply fan is located at the contact end between the module box and the inner liner seat, with its air outlet facing the backing surface of the inner liner seat.

[0023] A filter box is installed inside the module box and located on the air inlet side of the air supply fan. The filter box is filled with an activated carbon filter layer to purify the air supplied to the inner liner area.

[0024] Preferably, the seat back of the inner liner has ventilation micro-holes distributed on it, the ventilation micro-holes are connected to the air outlet of the air supply fan, and the distribution density of the ventilation micro-holes in the waist area and back area is greater than that in other areas.

[0025] Preferably, the base is detachably connected to the car seat via an ISOFIX connector, and the inner liner is provided with a buckle strap.

[0026] A method for using a smart child safety seat that prevents motion sickness and milk spillage includes the following steps:

[0027] S1. Secure the base to the car seat using the ISOFIX connector, place the child in the inner seat, and secure it with the buckle strap;

[0028] S2. During driving, the driving status detection unit detects the vehicle's acceleration, tilt angle and vibration signals in real time. The control unit determines the current driving status based on the signals and drives the air pump to independently inflate and deflate the air bags in each area through the corresponding miniature solenoid valve, so that the air bag pressure distribution is adapted to the current driving status and the child's body position.

[0029] S3. When the temperature in the inner liner area exceeds the preset range or the air quality is lower than the preset threshold, the control unit starts the air supply fan and sends the air filtered by the activated carbon filter layer into the seat surface area of ​​the inner liner.

[0030] S4. When the vehicle is subjected to a vertical impact, the seat cushion foam layer is vertically displaced on the load-bearing frame along the direction defined by the limiting wings through the elastic support net, absorbing and buffering the impact energy.

[0031] The above technical solution provides an anti-motion sickness and anti-milk spillage smart child safety seat and its usage method, which have the following beneficial effects:

[0032] This device uses multiple sets of airbags distributed in the left, right, waist, and head flanks of the inner liner. Combined with gyroscope sensors and miniature solenoid valves, it can adjust the inflation volume of each airbag in real time according to the dynamic conditions of the vehicle, such as acceleration, deceleration, and turning. This allows the surface of the airbags to actively conform to the child's body contours, forming a dynamic, embracing support. By maintaining the stability and predictability of the body posture, it helps to align the motion information received by the child's vestibular, visual, and proprioceptive systems, fundamentally reducing sensory conflict and lowering the incidence of motion sickness.

[0033] It can adjust the distribution of support pressure according to the changes in a child's body posture during travel. It can effectively solve the problem that traditional fixed foam filling structures or mechanical adjustment structures cannot adapt to children's body movements, reduce discomfort caused by long-term riding, avoid excessively high or low local pressure, reduce stress response caused by physical discomfort, and indirectly reduce the probability of motion sickness.

[0034] The pressure-reducing and shock-absorbing component of this invention adopts a three-stage composite structure: the outer layer is a cushion foam layer that comes into direct contact with the child, providing soft and comfortable daily support; the middle layer is an elastic support net composed of interwoven elastic ropes, utilizing its non-linear elastic characteristics to provide adaptive support; and the bottom layer is a load-bearing frame connected to the base, providing structural stability. Simultaneously, the displacement of the cushion foam layer is strictly limited to the vertical direction through the sliding pair of the limiting wings and guide protrusions.

[0035] The interwoven structure of the elastic support net exhibits differentiated response characteristics to vibrations of different frequencies. For high-frequency, low-amplitude vibrations (such as engine idling vibrations), the damping effect of the elastic ropes can effectively dissipate energy. For low-frequency, high-amplitude impacts (such as speed bumps), the large deformation capacity of the elastic net can provide flexible buffering to avoid rigid impacts. In the three-level structure, the foam layer mainly absorbs surface contact impacts, the elastic net mainly dissipates the vibration energy of the middle layer, and the load-bearing frame transfers the remaining energy to the base and disperses it to the vehicle body, forming a progressive energy management system.

[0036] Meanwhile, the elastic support net undergoes progressive compression upon vertical impact, dispersing the impact peak into a buffering process with a longer duration and lower amplitude. Guided by the limiting wings, the seat cushion foam layer only undergoes vertical displacement without horizontal slippage, ensuring a stable abdominal support surface. This reduces the peak abdominal pressure during vertical impacts from the car's movement, significantly decreasing the reflux of gastric contents caused by sudden changes in abdominal pressure and effectively reducing the occurrence of milk regurgitation.

[0037] It also integrates environmental control components, such as a fan and filter, to provide a comfortable riding environment for children. Continuous airflow circulation can reduce the temperature and humidity of the seat surface, reduce irritability and nausea caused by stuffiness, and further suppress motion sickness.
