[0070] To meet the childcare needs of families with children, various child seats specifically designed for children have emerged on the market. These include high chairs for easy feeding or dining, and car seats installed in vehicles to ensure the safety of children while traveling. These child seats utilize their structural features to achieve certain functional effects, providing convenience for parents while ensuring the comfort and safety of children. Currently, however, child seats do not adequately balance structural strength and overall weight.

[0071] Based on this, in order to solve the current technical problem that child car seats cannot effectively balance structural strength and overall weight, referring to Figures 1 to 12This utility model provides a child safety seat, which includes a seat body 100, a seat rear cover 200, and a seat lower cover 300. The seat body 100 has an outer peripheral wall 110, which includes an upper peripheral wall 111 and a lower peripheral wall 112. Along the circumferential direction of the upper peripheral wall 111, a first reinforcing rib 1111 is provided. For example, the seat body 100 and the first reinforcing rib 1111 can be an integrally formed structure. And / or, along the circumferential direction of the lower peripheral wall 112, a second reinforcing rib 1121 is provided. For example, the seat body 100 and the second reinforcing rib 1121 can be an integrally formed structure. The seat rear cover 200 is disposed on the upper peripheral wall 111 and covers the upper peripheral wall 111. For example, the seat back cover 200 and the seat body 100 can be connected together by bolts, or by welding, or by adhesive. The seat lower cover 300 is disposed on the lower peripheral wall 112 and covers the lower peripheral wall 112. For example, the seat lower cover 300 and the seat body 100 can be connected together by bolts, or by welding, or by adhesive. The wall thickness D1 of the seat body 100 satisfies: 1.5mm ≤ D1 ≤ 2.5mm; the thickness D2 of the seat back cover 200 satisfies: 1mm ≤ D2 ≤ 1.8mm; and the thickness D3 of the seat lower cover 300 satisfies: 1mm ≤ D3 ≤ 1.8mm. For example, the value of D1 can be 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, etc. The value of D2 can be 1mm, 1.2mm, 1.5mm, 1.6mm, 1.8mm, etc. The value of D3 can be 1mm, 1.2mm, 1.5mm, 1.6mm, 1.8mm, etc.

[0072] Specifically, in this embodiment, by reducing the wall thickness of the seat body 100, the seat rear cover 200, and the seat lower cover 300, the overall weight of the child safety seat can be effectively reduced, thereby facilitating the handling and transportation of the child safety seat and reducing transportation costs. Furthermore, by providing a first reinforcing rib 1111 and a second reinforcing rib 1121 on the outer peripheral wall 110 of the seat body 100, the overall strength of the child safety seat can be effectively improved, thereby preventing structural damage during handling or transportation and ensuring the structural stability and safety of the child safety seat during use. This child safety seat achieves a good balance between high structural strength and light overall weight.

[0073] Furthermore, covering the upper perimeter wall 111 with the rear seat cover 200 not only improves the structural integrity and strength of the child safety seat's back structure but also provides additional protection, ensuring the child is in a safer position when seated. Covering the lower perimeter wall 112 with the lower seat cover 300 not only improves the structural integrity and strength of the child safety seat's bottom structure but also helps ensure the stability of the connection between the child safety seat and the vehicle's mounting interface.

[0074] In some embodiments, refer to Figures 1 to 6 The seat body 100 has multiple sets of first ventilation holes 120 in its central area, which are distributed circumferentially along the edges of the central area. For example, each set may include multiple first ventilation holes 120, which can be circular, square, or oblong. The number or shape of the first ventilation holes 120 can be arbitrarily set based on actual production needs and aesthetic requirements.

[0075] Specifically, in this embodiment, when a child sits in the child safety seat, the child's back and buttocks areas correspond precisely to the middle area of ​​the seat body 100. Multiple sets of first ventilation holes 120 are provided in the middle area of ​​the seat body 100, each corresponding to the child's back and buttocks areas. These multiple ventilation holes 120 effectively promote airflow, thereby improving the air convection efficiency inside the child safety seat and increasing its breathability and comfort. The airflow path between the child safety seat and the external environment is as follows: air enters the interior of the child safety seat through the first ventilation holes 120 located at the edges; after internal airflow, the air exits through the first ventilation holes 120 or through other openings in the child safety seat, thus achieving airflow and heat dissipation within the child safety seat, making it cooler and more comfortable to use.

[0076] Since the center of the middle area of ​​the seat body 100 is the main stress point, the multiple sets of first ventilation holes 120 are distributed at the edges of the middle area of ​​the seat body 100 to ensure the structural strength of the seat body 100 and prevent the opening of the first ventilation holes 120 from reducing the overall structural strength of the seat body 100. This effectively improves the anti-collision performance of the child safety seat, extends the service life of the child safety seat, and ensures the safety of the child safety seat.

[0077] In some embodiments, refer to Figures 1 to 6The side area of ​​the seat body 100 is provided with multiple second vents 130, which are elongated. Designing the second vents 130 as elongated structures increases the opening area, thereby improving airflow between the child safety seat and the external environment and enhancing the seat's breathability. For example, the multiple second vents 130 can be arranged parallel to each other and at an angle, extending the opening path while also improving the aesthetics of the openings.

[0078] Specifically, in this embodiment, when a child is sitting in the child safety seat, the areas on both sides of the child's body correspond precisely to the side areas of the seat body 100. At this time, multiple second ventilation holes 130 are provided on the side areas of the seat body 100, each corresponding to one of the child's sides. These multiple second ventilation holes 130 ensure airflow between the child safety seat and the external environment, thereby improving the heat dissipation and breathability of the child safety seat, preventing overheating due to poor ventilation inside the seat, and ensuring the comfort of the child safety seat.

[0079] In some embodiments, refer to Figures 3 to 5 The first reinforcing rib 1111 has a sheet-like structure, and the upper peripheral wall 111 is provided with a plurality of first reinforcing ribs 1111, which are spaced apart on both sides of the upper peripheral wall 111. And / or, the second reinforcing rib 1121 has a sheet-like structure, and the lower peripheral wall 112 is provided with a plurality of second reinforcing ribs 1121, which are spaced apart on both sides of the lower peripheral wall 112.

[0080] Specifically, in this embodiment, the first reinforcing rib 1111 and the second reinforcing rib 1121 are designed as sheet-like structures, which can improve the overall lightweight of the seat body 100 and reduce the overall weight of the child safety seat. Moreover, the seat body 100 is provided with multiple first reinforcing ribs 1111 and multiple second reinforcing ribs 1121, which can improve the overall structural strength of the child safety seat and ensure the safety of the child safety seat in use.

[0081] In some embodiments, refer to Figures 3 to 5 A third reinforcing rib 1122 is provided at the edge of the lower peripheral wall 112 away from the upper peripheral wall 111. For example, the seat body 100 and the third reinforcing rib 1122 can be a one-piece molded structure.

[0082] Specifically, in this embodiment, when a child sits inside the child safety seat, the child's legs rest precisely on the edge of the lower circumferential wall 112 away from the upper circumferential wall 111. That is, the edge of the lower circumferential wall 112 away from the upper circumferential wall 111 is the primary support point for the child's legs. By adding a third reinforcing rib 1122 at this location, the structural strength of this area can be further enhanced, effectively preventing localized deformation or damage caused by concentrated loads. This, in turn, improves the structural stability and reliability of the child safety seat and extends its service life.

[0083] In addition, during impact or drop tests of child safety seats, the edge of the lower circumferential wall 112 furthest from the upper circumferential wall 111 experiences the greatest impact force. In other words, the edge of the lower circumferential wall 112 furthest from the upper circumferential wall 111 is most susceptible to damage. By adding a third reinforcing rib 1122 at this location, the child safety seat can successfully complete the impact or drop test and avoid localized whitening of the child safety seat.

[0084] In some embodiments, refer to Figure 7 and Figure 8 The surface of the seat back cover 200 is provided with a protrusion 210. For example, the protrusion 210 may be provided on the side of the seat back cover 200 close to the seat body 100, or the protrusion 210 may be provided on the side of the seat back cover 200 away from the seat body 100. The protrusion 210 and the seat back cover 200 can be an integrally formed structure. And / or, the surface of the seat lower cover 300 is provided with a protrusion 210. For example, the protrusion 210 may be provided on the side of the seat lower cover 300 close to the seat body 100, or the protrusion 210 may be provided on the side of the seat lower cover 300 away from the seat body 100. The protrusion 210 and the seat lower cover 300 can be an integrally formed structure.

[0085] Specifically, in this embodiment, by providing a protrusion 210 on the surface of the seat back cover 200, the local wall thickness of the seat back cover 200 can be increased, improving the local structural strength of the seat back cover 200. This allows the seat back cover 200 to provide effective support for the upper peripheral wall 111, ensuring the reliability of the child when leaning against the child safety seat. By providing a protrusion 210 on the surface of the seat lower cover 300, the local wall thickness of the seat lower cover 300 can be increased, improving the local structural strength of the seat lower cover 300. This allows the seat lower cover 300 to provide effective support for the lower peripheral wall 112, improving the overall durability and load-bearing capacity of the child safety seat. Especially under prolonged use or under certain loads, the protrusion 210 helps to distribute pressure and reduce potential damage.

[0086] In addition, when conducting impact or drop tests on child safety seats, by adding a protrusion 210 to the surface of the seat back cover 200 or the seat bottom cover 300, it is possible to prevent the seat back cover 200 or the seat bottom cover 300 from turning white in some areas, ensuring that the seat back cover 200 or the seat bottom cover 300 can pass the impact or drop test smoothly, and reducing the damage rate of the seat back cover 200 or the seat bottom cover 300.

[0087] In some embodiments, refer to Figure 7 The seat back cover 200 is provided with multiple third ventilation holes 220. For example, the third ventilation holes 220 can be circular, oblong, or square, etc. Pointing from one end of the seat back cover 200 to the opposite end (which can be any two opposite ends of the seat back cover 200), the density of the multiple third ventilation holes 220 gradually increases, and the diameter of the multiple third ventilation holes 220 gradually increases. That is, the multiple third ventilation holes 220 gradually expand radially. This opening method ensures good breathability of the seat back cover 200 while improving its overall aesthetics. The total opening area S1 of the multiple third ventilation holes 220 and the total surface area S2 of the seat back cover 200 satisfy the following relationship: 50% ≤ S1 / S2 ≤ 90%. For example, the values ​​of S1 / S2 can be 50%, 60%, 70%, 80%, 90%, etc.

[0088] Specifically, in this embodiment, S1 / S2 satisfies the above-mentioned range. On the one hand, it avoids the total opening area of ​​the third vent 220 being too small (for example, the value of S1 / S2 is 10%, 20%, 30%, etc.), which would affect the ventilation performance of the seat back cover 200, resulting in poor comfort of the child safety seat and making it impossible for the child safety seat to achieve effective heat dissipation. On the other hand, it avoids the total opening area of ​​the third vent 220 being too large (for example, the value of S1 / S2 is 95%, 98%, 99%, etc.), which would affect the overall structural strength of the seat back cover 200, resulting in a reduction in the overall stability and reliability of the child safety seat and making it impossible to guarantee the safety of the child safety seat.

[0089] In some embodiments, refer to Figure 8The seat cover 300 is provided with multiple fourth ventilation holes 310. For example, the fourth ventilation holes 310 can be circular, oblong, or square, etc. Pointing from one end of the seat cover 300 to the opposite end (which can be any two opposite ends of the seat cover 300), the density of the multiple fourth ventilation holes 310 gradually increases, and the diameter of the multiple fourth ventilation holes 310 gradually increases. That is, the multiple fourth ventilation holes 310 gradually expand radially. This opening method ensures good air permeability of the seat cover 300 while improving its overall aesthetics. The total opening area S3 of the multiple fourth ventilation holes 310 and the total surface area S4 of the seat cover 300 satisfy the following relationship: 20% ≤ S3 / S4 ≤ 50%. For example, the values ​​of S3 / S4 can be 20%, 30%, 40%, 45%, 50%, etc.

[0090] Specifically, in this embodiment, S3 / S4 satisfies the above-mentioned range. On the one hand, it avoids the total opening area of ​​the fourth vent 310 being too small (for example, the value of S3 / S4 is 5%, 10%, 15%, etc.), which would affect the ventilation performance of the seat cover 300, resulting in poor comfort of the child safety seat and making it impossible for the child safety seat to achieve effective heat dissipation. On the other hand, it avoids the total opening area of ​​the fourth vent 310 being too large (for example, the value of S3 / S4 is 70%, 80%, 90%, etc.), which would affect the overall structural strength of the seat cover 300, resulting in a reduction in the overall stability and reliability of the child safety seat and making it impossible to guarantee the safety of the child safety seat.

[0091] It should be noted that, since the pressure on the lower seat cover 300 is greater than that on the rear seat cover 200, the total opening area of ​​the fourth vent 310 is smaller than that of the third vent 220.

[0092] In some embodiments, refer to Figure 1 , Figures 9 to 12 A seat base 400 is provided on the side of the seat cover 300 away from the seat body 100. The seat base 400 includes a first cover 410 and a second cover 420. The first cover 410 is provided with a first positioning part 411, and the second cover 420 is provided with a second positioning part 421. The second positioning part 421 and the first positioning part 411 are adapted to engage the first cover 410 and the second cover 420. For example, the first positioning part 411 can be a positioning hole, and the second positioning part 421 can be a positioning pin. Alternatively, if the first positioning part 411 can be a positioning pin, the second positioning part 421 can be a positioning hole.

[0093] Specifically, in this embodiment, the child safety seat can be fixed in a target position using the seat base 400. For example, the child safety seat can be fixed to a car seat using the seat base 400, so that children can travel safely in the car. When assembling the seat base 400, the first cover 410 and the second cover 420 are first positioned opposite each other, and the first positioning part 411 and the second positioning part 421 are aligned. Then, force is applied to the first cover 410 or the second cover 420, causing the first positioning part 411 and the second positioning part 421 to snap together, thereby achieving the engagement between the first cover 410 and the second cover 420. When disassembling the seat base 400, a separating force is applied to the first cover 410 and the second cover 420. After the first positioning part 411 and the second positioning part 421 separate from each other, the first cover 410 and the second cover 420 can be disassembled and separated. The first cover 410 and the second cover 420 are connected by a snap-fit ​​mechanism, which allows for assembly or disassembly without the need for additional auxiliary tools, saving time and effort, and ensuring the stability of the connection between the first cover 410 and the second cover 420.

[0094] In some embodiments, refer to Figures 9 to 12 The first positioning part 411 has a recessed part 4111 near the end of the first cover 410 (in the art, the recessed part 4111 can be referred to as a "doghouse design"), and a fourth reinforcing rib 4112 is provided around the outer periphery of the recessed part 4111. For example, the fourth reinforcing rib 4112 and the first cover 410 can be an integrally formed structure.

[0095] Specifically, in this embodiment, in order to improve the overall strength of the seat base 400, a "doghouse design" is made at the bottom of the first positioning part 411 of the first cover 410, and a fourth reinforcing rib 4112 is provided around the "doghouse structure", which can further improve the fastening strength of the seat base 400, better lock the first cover 410 and the second cover 420 together, and improve the connection fastness between the first cover 410 and the second cover 420.

[0096] Alternatively, in some embodiments, refer to Figures 9 to 12 The second positioning part 421 is provided with a recessed part 4111 at the end near the second cover 420 (in the art, the recessed part 4111 can also be referred to as "dog kennel design"), and a fourth reinforcing rib 4112 is provided around the circumference of the recessed part 4111.

[0097] Referring to the above embodiment, by implementing a "doghouse design" at the bottom of the second positioning part 421 of the second cover 420 and providing a fourth reinforcing rib 4112 around the "doghouse structure", the fastening strength of the seat base 400 can be further improved, the first cover 410 and the second cover 420 can be better locked together, and the connection between the first cover 410 and the second cover 420 can be improved.

[0098] Correspondingly, another embodiment of this utility model also provides a child safety seat system, which includes the child safety seat in any of the above embodiments. The child safety seat system also includes a base, to which the child safety seat is configured to be connected for securing the child safety seat.

[0099] Specifically, in this embodiment, by using the aforementioned child safety seat, it is convenient to move the child safety seat onto the child safety seat system for assembly or disassembly, and by using the aforementioned child safety seat, the safety of children when using this child safety seat system for travel can be guaranteed.

[0100] Thanks to the improvements to the child safety seats described above, the child safety seat system in this embodiment has the same technical effects as the aforementioned child safety seats, which will not be repeated here.

[0101] It should be noted that other aspects of the child safety seat and child safety seat system disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0102] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
