[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] For infants in the Q0-Q3 stage, whose spines are not yet fully developed, a rear-facing sitting posture with a large angle of inclination is required to disperse the impact force during the ride and avoid spinal injury. For infants in the Q1.5-Q10 stage, whose sitting posture is gradually approaching that of adults, a forward-facing sitting posture with a small angle of inclination is required to ensure visibility and riding comfort. Therefore, this embodiment discloses a child seat, such as... Figure 1As shown, in this embodiment, the child seat includes a seat body 1 and a base 2. The seat body 1 includes a smoothly transitioned backrest section 11, a bent section 12, and a seat section 13. The base 2 is installed on the outside of the seat body 1, and the base 2 extends in the same direction as the seat body 1 and fits against the outside of the seat body 1. The bottom surface of the base 2 corresponding to the bent section 12 is the first bottom surface 21, which is a plane. The bottom surface of the base 2 corresponding to the seat section 13 is the second bottom surface 22, which is also a plane. The first bottom surface 21 and the second bottom surface 22 are set at an angle. When the child seat is in the toddler position and is placed face down, the first bottom surface 21 can fit against the seat of the car seat. When the child seat is in the child position and is placed face up, the second bottom surface 22 can fit against the seat of the car seat. The seat body 1 is connected by the backrest section 11, The smooth transition design of the bending section 12 and the seat section 13 provides a support base that conforms to the body curves of infants and children of different ages. The first bottom surface 21 and the second bottom surface 22 are set at an angle and are both flat. When the infants are in the early childhood stage (i.e., Q0-Q3 stage), they can fit the car seat with the first bottom surface 21 (i.e., rear-facing sitting at a large angle), forming a more inclined angle that conforms to the spinal development and car safety of young infants and children. When the children are in the early childhood stage (i.e., Q1.5-Q10 stage), they can switch to the second bottom surface 22 (i.e., forward-facing sitting at a small angle), obtaining a more gentle sitting angle that conforms to their body size and sitting habits. The switching between the two states covers the sitting angle and support needs of infants and children from birth to 10 years old at different growth stages, which can meet the needs of forward and rear-facing installation of child seats and meet the needs of the entire life cycle without the need to replace the seat.

[0038] Preferably, in this embodiment, the base 2 and the seat body 1 are integrally formed, making the base 2 and the backrest section 11, bending section 12, and seat section 13 of the seat body 1 form a stable and seamless whole. This enhances the overall load-bearing capacity and impact resistance of the seat, avoids the risk of loosening and displacement that may occur due to the separate connection between the base 2 and the seat body 1, and improves the safety of infants and children of different ages when riding in a car. At the same time, the child seat does not require an additional independent fixing base 2. The base 2, which is integrally formed with the seat body 1, not only serves the function of adapting to different age groups through the switching between the two bottom surfaces, but also directly serves as the connection and support structure between the seat and the car seat. Therefore, there is no need to purchase an additional independent base 2. Parents only need to use the car's built-in seat belt to fix the child seat, which saves the purchase cost of an additional base 2, meets the demand for economic benefits, simplifies the installation process, and avoids the burden of use and storage caused by an independent base 2. Ultimately, it achieves the dual goals of adaptability to all age groups and low-cost and convenient use.

[0039] Preferably, such as Figure 1As shown, in this embodiment, the first bottom surface 21 and the second bottom surface 22 have a smooth transition, which makes the overall structure of the base 2 more coherent and without abrupt edges. When the child seat is in toddler mode or switching to child mode, it avoids the problem of the base 2 not fitting tightly with the car seat and gaps due to sharp turns at the bottom joint. This ensures that the child seat can be placed stably in both usage states, improving the safety of riding in the car. The smooth transition design echoes the smooth transition of the backrest section 11, the bending section 12, and the seat section 13 of the seat body 1, making the overall appearance of the child seat smoother, while avoiding the risk of bumps and knocks to infants and children that may be caused by sharp edges at the joint.

[0040] Preferably, such as Figures 1-3 As shown, in this embodiment, two bases 2 are provided, symmetrically arranged about the central axis of the seat body 1. This provides balanced support for the seat body 1, ensuring that the seat body 1 maintains a stable seating angle regardless of whether the child seat is in a toddler or child position. This prevents the seat from tilting or shifting due to uneven force on one side, thereby improving the overall structural stability and safety of the seat. It provides a stable and reliable seating environment for infants and toddlers of different ages, effectively distributing the pressure of the infant's body on the seat and reducing the impact of bumps or sudden situations during travel. In other embodiments, one, three, or four bases 2 may be provided.

[0041] Preferably, such as Figure 1 As shown, in this embodiment, the end of the seat segment 13 is curved upwards, and the base 2 also includes a first abutment surface 23. The end of the second bottom surface 22 is connected to the end of the seat segment 13 to form the first abutment surface 23. The first abutment surface 23 and the second bottom surface 22 are set at an angle. The first abutment surface 23 is a plane. When the child seat is placed in the reverse position, the first abutment surface 23 can fit against the back of the car seat, which can further enhance the connection stability between the child seat and the car seat when the child is sitting, and prevent the seat from shifting or shaking during the child's ride. At the same time, in conjunction with the fit between the first bottom surface 21 and the seat of the car seat, a double support and fixation is formed for the child's riding state, which better adapts to the spinal development characteristics of young infants and improves their safety and comfort when riding in the reverse position. Moreover, stable installation in this state can be achieved without additional accessories, further ensuring the safety needs of young children during the entire life cycle of use.

[0042] Preferably, such as Figure 1As shown, in this embodiment, the first contact surface 23 and the second bottom surface 22 are smoothly transitioned, which can avoid the formation of sharp edges or abrupt turns at the two connecting parts. This not only prevents young children from being scratched or bumped when riding or touching the seat, thus avoiding safety hazards, but also reduces the risk of adults getting their hands scratched when installing or adjusting the seat. It also makes the overall structure of the base 2 more streamlined, avoiding stress concentration that could cause cracks or damage to the base 2 during long-term use, thereby extending the service life of the seat.

[0043] Preferably, such as Figure 1 As shown, in this embodiment, the base 2 also includes a second abutment surface 24. The bottom surface of the base 2 corresponding to the backrest section 11 is the second abutment surface 24. The second abutment surface 24 is set at an angle to the first bottom surface 21. The second abutment surface 24 is a plane. When the child seat is placed facing forward, the second abutment surface 24 can fit against the backrest of the car seat. This allows the child seat to achieve a gentle sitting angle not only by fitting against the car seat seat through the second bottom surface 22, but also by forming bidirectional support through the fit between the second abutment surface 24 and the car seat back. This further enhances the stability of the connection between the child seat and the car seat, preventing the seat from shaking or shifting during the infant's ride. At the same time, it allows the back of the infant in the child stage to form a more fitted support relationship with the child seat backrest and the car seat backrest, better adapting to their body size and sitting habits, improving the comfort and safety of riding, and eliminating the need to replace the seat, continuously meeting the riding needs of the infant in this stage, and improving the adaptability and reliability of use throughout the entire cycle.

[0044] Preferably, such as Figure 1 As shown, in this embodiment, the second contact surface 24 and the first bottom surface 21 are smoothly transitioned, which can prevent infants from accidentally touching the connecting parts during getting on and off the seat or during the ride, thus preventing safety hazards such as bumps and scratches. This ensures the safety of infants when riding and makes the overall structure of the base 2 more streamlined. It does not damage the support base of the child seat itself that conforms to the curve of the infant's body, nor does it affect the fit between the seat and the car seat and backrest due to the abruptness of the connection when switching to the toddler or child state.

[0045] Preferably, such as Figure 1 and Figure 2As shown, in this embodiment, the child seat also includes an anti-slip component 3, which is installed on the first bottom surface 21 and the second bottom surface 22. This anti-slip component 3 enhances the friction between the first bottom surface 21, the second bottom surface 22 and the car seat when the child seat is in toddler or child mode, respectively. This effectively prevents the child seat from sliding or shifting due to changes in road conditions during vehicle operation, further improving the stability and safety of infants and toddlers at different growth stages. Simultaneously, combined with the body-conforming support design of the seat body 1 and the angle settings of the double bottom surfaces to adapt to different stages, this allows for continuous use without needing to replace the seat. It not only meets the infant's and toddler's seating angle and support needs during growth but also provides more reliable protection through anti-slip protection. In other embodiments, the anti-slip component 3 may be installed only on the first bottom surface 21 or the second bottom surface 22.

[0046] Preferably, in this embodiment, the anti-slip component 3 is also installed on the first contact surface 23 and the second contact surface 24. When the child seat is in the toddler position, the first contact surface 23 is in contact with the back of the car seat, and the anti-slip component 3 can effectively increase the friction between the two, preventing the child seat from shifting or shaking due to the toddler's movements. Combined with the contact between the first bottom surface 21 and the car seat, it provides more stable double support and fixation for the toddler, conforming to the spinal development characteristics of young infants and improving the safety and comfort of rear-facing seating. When the child seat is in the child position, the second contact surface 24 is in contact with the back of the car seat, and the anti-slip component 3 also increases the friction at the contact point. Not only does the second bottom surface 22 achieve a gentle seating angle by contacting the car seat, but the second contact surface 24 also forms bidirectional support by contacting the back of the car seat, preventing the seat from shaking or shifting. This allows the back of the toddler to better contact with the back of the child seat and the back of the car seat, improving seating comfort and safety, and ensuring stability and safety at different stages throughout the entire life cycle of use. In other embodiments, the anti-slip element 3 may be provided only on the first abutment surface 23 or the second abutment surface 24.

[0047] Preferably, in this embodiment, the child seat also includes a soft padding layer, which is disposed on the inner side of the seat body 1. The soft padding layer is made of breathable cotton material, and the surface of the soft padding layer is provided with a honeycomb mesh structure. It can further conform to the body curves of infants and children of different ages by means of its softness. On the basis of the basic support of the seat body 1, it provides infants and children with a more comfortable touch and a sense of being wrapped up, and relieves the discomfort of sitting for a long time. The breathable cotton material itself has good breathability, and the honeycomb mesh structure can greatly improve the air circulation efficiency, effectively reduce the stuffiness of the part of the infant's body in contact with the padding layer when sitting, avoid the accumulation of sweat, and keep the skin dry. At the same time, the soft padding layer can also form a certain cushion for the infant's body. When the vehicle encounters bumps or sudden situations, it helps to reduce the impact of external impact on the infant's body, further improving the safety and comfort of sitting. In conjunction with the design of the seat body 1 to adapt to the sitting needs of infants and children at different growth stages, it allows infants and children to obtain a suitable support angle and have a continuously comfortable sitting experience throughout the entire period of use.

[0048] Preferably, in this embodiment, the child seat also includes a seat belt assembly, which includes a shoulder strap, a waist belt, and a buckle. The shoulder strap is connected to the backrest section 11, and the waist belt is connected to the seat section 13. The buckle can detachably connect the shoulder strap and waist belt to the seat body 1. It can form a dual constraint from above the back and below the buttocks for infants and children of different ages in toddler and child states, respectively, to adapt to their sitting angle and body curve, thus achieving a stable fixation of the infant's body. The detachable buckle design makes it convenient for parents to quickly put on and take off the seat belt according to the needs of the infant entering and exiting, improving the ease of use. The shoulder strap and waist belt, which are precisely connected to the various functional sections of the seat body 1, can fit closely to the infant's body during the ride, effectively dispersing the impact force that may be generated during the ride, and further ensuring the safety of infants and children at different stages of growth.

[0049] Preferably, in this embodiment, both the shoulder strap and the waist belt are equipped with length adjustment devices. These devices can adjust the length of the shoulder strap and waist belt according to the changes in height and body shape of the infant at different growth stages. This ensures that the shoulder strap always fits the curve of the infant's back and shoulders, and the waist belt fits the infant's waist and hip size closely. This breaks the limitation of fixed-length seat belts on the infant's growth stages, allowing the same set of seat belt components to accompany the infant through different growth stages. This perfectly matches the core design of the child seat for all-cycle use, eliminating the need for additional seat belt replacements and reducing usage costs. Through precise length adjustment, the seat belt can always provide optimal tightness to securely restrain the infant, preventing the infant's body from swaying and losing its protective function due to being too loose, and also preventing the infant's body from being compressed and affecting riding comfort due to being too tight. This ensures the safety of infants at different stages of their journey while improving their riding experience.

[0050] Preferably, such as Figures 1-3 As shown, in this embodiment, the child seat also includes armrests 4, which are disposed on both sides of the seat body 1. The armrests 4 are integrally formed with the seat body 1, and the upper surface of the armrests 4 is an arc surface. The integral forming design can enhance the stability of the connection between the armrests 4 and the seat body 1, avoid safety hazards to infants and children due to loose splicing structure, simplify the production process, and improve the durability of the overall structure. At the same time, the armrests 4 on both sides can also provide stable support for the infant's arms when riding, conform to the infant's natural sitting posture habits, reduce the fatigue caused by the arms being suspended in the air, and the arc surface design can effectively avoid the risk of bumps and scratches that may be caused by sharp edges and corners, further ensuring the safety and comfort of the infant when riding.

[0051] Preferably, such as Figures 1-3 As shown, in this embodiment, the child seat also includes side impact wings 5. Side impact wings 5 ​​are provided on both sides of the seat body 1 corresponding to the infant's head position. The side impact wings 5 ​​protrude inward to form an arc-shaped protective space. The side impact wings 5 ​​are provided with cushioning material inside, which can quickly buffer and disperse the impact force from the side when the vehicle encounters a side collision or sudden turn, so as to avoid the infant's head being directly hit violently. The arc-shaped structure of the side impact wings 5 ​​can also stably wrap the infant's head from both sides, reducing the amplitude of head shaking during the collision. The arc-shaped design that conforms to the head contour and the combination of cushioning material can also provide comfortable support for the infant's head during daily riding, which not only further improves the safety of infants at different growth stages when riding, but also ensures riding comfort.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
