Description

Technical Field

[0001] This utility model relates to the field of child safety products technology, specifically to a child safety seat. Background Technology

[0002] Child car seats are designed specifically for children of different ages, installed in cars, and effectively improve children's safety while traveling. In the event of a collision or sudden deceleration, they reduce the impact force on children and restrict their body movement, thus minimizing injury and ensuring their safety while traveling.

[0003] Most child seats nowadays are equipped with headrests. In the event of an accident during travel, a child's head is likely to hit the headrest directly. However, because children grow quickly, the headrests of child seats need to be height-adjustable. Upon impact, the design of the adjustment function makes the sliding part of the headrest easily deformed by the impact force from the child's head or external impact forces. This can affect the smoothness of the headrest height adjustment, and in severe impacts, it can even damage the sliding part, thus losing its protective function for the child's head.

[0065] Child car seats are designed specifically for children of different ages, installed in cars, and effectively improve children's safety while traveling. In the event of a collision or sudden deceleration, they reduce the impact force on children and restrict their body movement, thus minimizing injury and ensuring their safety while traveling.

[0066] Most child seats nowadays are equipped with headrests. In the event of an accident during travel, a child's head is likely to hit the headrest directly. However, because children grow quickly, the headrests of child seats need to be height-adjustable. Upon impact, the design of the adjustment function makes the sliding part of the headrest easily deformed by the impact force from the child's head or external impact forces. This not only affects the smoothness of the headrest height adjustment, but in severe impacts, it can even damage the sliding part, thus losing its protective function for the child's head.

[0067] To solve the above technical problems, such as Figures 1 to 14 As shown, this embodiment proposes a child safety seat 1000, which includes a seat body 40 and a headrest assembly 300. The headrest assembly 300 is movably disposed at one end of the seat body 40 along a first direction a and located on the side of the seat body 40 facing the child along a second direction b, wherein the first direction a and the second direction b are perpendicular. The headrest assembly 300 has a headrest body 10. Along the first direction a, a sliding part 12 is provided at the end of the headrest body 10 facing the seat body 40, and the sliding part 12 extends in a direction away from the headrest body 10 and is adapted to the seat body 40. There are two sliding parts 12, and the two sliding parts 12 are spaced apart along a third direction c, which is perpendicular to the first direction a and the second direction b. Along the second direction b, a reinforcing structure 13 is provided on the side of the sliding part 12 facing the seat body 40.

[0068] Specifically, by providing a reinforcing structure 13 on the side of the sliding part 12 facing the seat body 40, the structural strength of the sliding part 12 is improved, thereby reducing the deformation of the sliding part 12 during impact or long-term use. This not only helps to improve the smoothness of headrest height adjustment, but also improves the safety of the headrest assembly 300.

[0069] It is necessary to understand that, such as Figure 1 and Figure 2As shown, the child safety seat 1000 includes a base assembly 200, a body assembly 100, a headrest assembly 300, and a headrest height adjustment assembly 400. The base assembly 200 is used to place the seat on a car seat or the ground. The body assembly 100 is positioned above the base assembly 200 for a child to sit on. In this embodiment, the body assembly 100 includes a seat body 40, an outer shell 60, and side wing buffers (not shown in the figure). The seat body 40 is movably mounted on the base assembly 200. The side wing buffers are located on the side of the seat body 40 facing the child, and are designed to contact the child to protect the child in the event of an impact. The outer shell 60 is connected to the side of the seat body 40 facing away from the child. Specifically, the outer shell 60 includes a side cover 61 and a rear cover 62. The side cover 61 includes an upper side cover 611 and a lower side cover (not shown in the figure).

[0070] In this embodiment, the headrest assembly 300 is disposed on the body assembly 100 and is used to contact the child's head to protect the head. The headrest height adjustment assembly 400 is disposed between the headrest assembly 300 and the body assembly 100 and is used to adjust the height of the headrest assembly 300 on the body assembly 100. Along the first direction a, the headrest assembly 300 is movably disposed on the body assembly 100 via the headrest height adjustment assembly 400, wherein the first direction a is the vertical direction (or the height direction).

[0071] like Figures 1 to 5 As shown, the headrest assembly 300 is located along the second direction b on the side of the seat body 40 facing the child, that is, the side (inner side) of the seat body 40 that supports the child. The first direction a is perpendicular to the second direction b, which is the front-rear direction of the child safety seat 1000 (or the length direction of the seat body 40). In this embodiment, the headrest assembly 300 includes a headrest body 10, a headrest side plate 20, and a headrest buffer 30. The headrest body 10 includes a main body 11 and a sliding part 12. The main body 11 includes a second support plate 111 and two side plates 112. The side plates 112 are arranged at opposite ends of the second support plate 111 along the third direction c, thereby forming a U-shaped structure. This allows the main body 11 to fit the child's head, helping to reduce the child's activity space and improve the protection of the head.

[0072] Along the first direction a, a mounting structure 113 is provided at one end (bottom end) of the main body 11 facing the seat body 40. The control part of the headrest height adjustment assembly 400 is connected to the mounting structure 113 to clamp the first support plate 45 of the seat body 40, wherein the first support plate 45 can support the child's back. Optionally, the mounting structure 113 includes a positioning groove and a fixing hole for mounting and fixing the control part of the headrest height adjustment assembly 400. In this embodiment, the headrest height adjustment assembly 400 can adopt an existing structure, and this application does not impose any restrictions on it.

[0073] It is important to further understand that a sliding part 12 is provided at the bottom end of the headrest body 10. In this embodiment, there are two sliding parts 12, and the two sliding parts 12 are spaced apart along a third direction c. The third direction c is perpendicular to the first direction a and the second direction b, that is, the third direction c is the width direction of the seat body 40. Optionally, the two sliding parts 12 are respectively provided at the connection between the second support plate 111 and the side plate 112. At the same time, there are two mounting structures 113, and the two mounting structures 113 are spaced apart along the third direction c, and each is connected to one sliding part 12. This not only helps to improve the structural strength of the headrest body 10, but also improves the strength of the mounting structure 113, thereby ensuring the connection effect between the headrest height adjustment group 400 and the seat body 40.

[0074] like Figures 1 to 6 As shown, the sliding portion 12 extends away from the headrest body 10 and is adapted to the seat body 40. In this embodiment, the sliding portion 12 has a plate-like structure and is conformally arranged to the backrest structure of the seat body 40, thereby preventing the sliding portion 12 from being affected by the seat body 40 when adjusting the height of the headrest assembly 300. Along the second direction b, a reinforcing structure 13 is provided on the side of the sliding portion 12 facing the seat body 40. The reinforcement structure 13 further improves the structural strength of the headrest body 10 and the strength of the mounting structure 113.

[0075] In this embodiment, the reinforcing structure 13 includes first reinforcing ribs 131 and first reinforcing rib plates 132. The number of first reinforcing ribs 131 is plurality of, and the plurality of first reinforcing ribs 131 are spaced apart along a first direction a. The first reinforcing rib plates 132 extend along the first direction a and are connected to opposite ends of the sliding portion 12. The first reinforcing rib plates 132 are connected to all the first reinforcing ribs 131. The arrangement of the first reinforcing rib plates 132 and the plurality of first reinforcing ribs 131 helps to further improve the structural strength of the sliding portion 12, thereby making the sliding portion 12 less prone to deformation, improving the smoothness of the headrest assembly 300 during height adjustment, and enhancing the reliability of the headrest assembly 300.

[0076] It should be noted that, in addition to the reinforcing structure 13 composed of the first reinforcing rib 131 and the first reinforcing rib plate 132 described above, the reinforcing structure 13 can also be configured in other shapes, such as using multiple X-shaped reinforcing ribs arranged sequentially along the first direction a, or using multiple reinforcing ribs with different extension directions, and multiple reinforcing ribs arranged in an interlaced manner, etc. This application does not impose any restrictions on this.

[0077] What needs further understanding is, such as Figures 3 to 6 As shown, the sliding part 12 has a receiving groove on its side facing the seat body 40. A reinforcing structure 13 is disposed in the receiving groove and divides it into multiple reinforcing grooves 121. The receiving groove, in conjunction with the reinforcing structure 13, further improves the structural strength of the sliding part 12, making it less prone to deformation. In this embodiment, the sliding part 12 has a receiving groove on its side facing the seat body 40. The receiving groove is recessed along the second direction b and in a direction away from the seat body 40. At this time, along the third direction c, a first side edge 122 and a second side edge 123 are formed at both ends of the receiving groove. The first side edge 122 is closer to the mounting structure 113 than the second side edge 123, and along the third direction c, the depth of the receiving groove near the first side edge 122 is less than or equal to the depth of the receiving groove away from the second side edge 123. Optionally, from the direction of the headrest assembly 300 towards the base assembly 200, the depth of the receiving groove near the second side edge 123 remains constant and then gradually decreases. This design helps to better match the position of the sliding part 12 and ensures the connection effect between the main body and the side plate 112.

[0078] In this embodiment, the first reinforcing rib 131 is disposed inside the receiving groove, and along the third direction c, the two ends of the first reinforcing rib 131 are connected to the first side edge 122 and the second side edge 123, respectively. Multiple first reinforcing ribs 131 are spaced apart inside the receiving groove along the first direction a, dividing the receiving groove into multiple reinforcing grooves 121. Simultaneously, along the third direction c, a first reinforcing rib plate 132 is disposed at the middle position of the first reinforcing rib 131, dividing each first reinforcing rib 131 into two parts. This results in the receiving groove being formed as multiple reinforcing grooves 121 arranged in an array. This arrangement helps reduce the manufacturing difficulty of the sliding part 12 and the reinforcing structure 13, and improves manufacturing efficiency.

[0079] Furthermore, the reinforcing structure 13 also includes a first reinforcing rib 133, which is disposed in the reinforcing groove 121. One end of the first reinforcing rib 133 is connected to the first reinforcing rib plate 132, and the other end is connected to the side edge of the receiving groove. By providing the first reinforcing rib 133, the structural strength of the sliding part 12 is further improved.

[0080] It is understood that the reinforcing groove 121 may be provided with one or more first reinforcing ribs 133 to further enhance the structural strength of the sliding part 12 by reinforcing the reinforcing groove 121. This application does not impose any restrictions on this. Meanwhile, along the third direction c, one end of the first reinforcing rib 133 is connected to the first reinforcing rib plate 132, and the other end is connected to the first side edge 122 or the second side edge 123 of the receiving groove. Optionally, the extending direction of the first reinforcing rib 133 may be the same as or intersect with the extending direction of the first reinforcing rib 131. This application does not impose any restrictions on this.

[0081] like Figures 3 to 6 As shown, there are multiple first reinforcing ribs 133, with at most one first reinforcing rib 133 provided in each reinforcing groove 121. In this embodiment, there are three first reinforcing ribs 133, and the three first reinforcing ribs 133 are respectively provided in three reinforcing grooves 121 near the mounting structure 113. Optionally, along the first direction a, the first reinforcing rib 133 is provided in the middle of two adjacent first reinforcing ribs 131, and the extending direction of the first reinforcing rib 133 intersects with the extending direction of the first reinforcing rib 131, that is, the first reinforcing rib 133 is inclinedly provided in the reinforcing groove 121. This arrangement helps to further improve the structural strength of the connection between the sliding part 12 and the mounting structure 113, which not only helps to improve the connection strength between the sliding part 12 and the mounting structure 113, but also improves the impact resistance of the headrest body 10, making it less prone to deformation.

[0082] It is important to further understand that, along the third direction c, the inclination directions of two adjacent reinforcing ribs are different, which can further improve the structural strength of the reinforcing groove 121. In this embodiment, along the first direction a, the inclination directions of the two ends of the three first reinforcing ribs 133 are the same, which helps to reduce the manufacturing difficulty of the sliding part 12.

[0083] In addition, the number and arrangement of the first reinforcing ribs 133 can be set to other shapes besides the structure described above, such as extending along the third direction c, or each reinforcing groove 121 is provided with a first reinforcing rib 133. This application does not impose any restrictions on this.

[0084] Furthermore, the seat body 40 has a first reinforcing region 41 and a second reinforcing region 42 spaced apart along a first direction a, and a first support plate 45 for supporting the child's back is provided between the first reinforcing region 41 and the second reinforcing region 42.

[0085] Specifically, by setting the first reinforcing region 41 and the second reinforcing region 42, the connection strength between the first support plate 45 and other parts of the seat body 40 can be improved, thereby greatly enhancing the local strength of the seat body 40 and improving the problem of local cracking of the seat body 40 during impact tests.

[0086] It is necessary to understand that, such as Figure 7 As shown, in this embodiment, the seat body 40 has a first support plate 45, and the first support plate 45 is sandwiched between the headrest body 10 and the control part of the headrest height adjustment group 400. Along the third direction c, the opposite sides of the first support plate 45 are hollowed out. At this time, along the first direction a, the opposite ends of the first support plate 45 are connected and fixed to the seat body 40. During the impact test, the two ends of the first support plate 45 connected to the seat body 40 are prone to breakage.

[0087] It is understood that the first reinforcing region 41 and the second reinforcing region 42 can be strengthened by providing a groove structure. The first reinforcing region 41 and the second reinforcing region 42 can also be strengthened by providing reinforcing ribs or reinforcing plates. Simultaneously, the first reinforcing region 41 and the second reinforcing region 42 can be respectively disposed on the first support plate 45, located at both ends where the first support plate 45 connects to the seat body 40. Alternatively, the first reinforcing region 41 and the second reinforcing region 42 can be respectively disposed on the seat body 40, close to the two ends where the first support plate 45 connects to the seat body 40. This application does not impose further limitations in this regard.

[0088] It should be noted that in this embodiment, the first reinforcing region 41 is located above the seat body 40 and is provided corresponding to the through-hole 411, which is the anchoring interface on the child safety seat 1000 for fixing the safety seat. In this case, the provision of the first reinforcing region 41 helps to improve the fixing effect of the child safety seat 1000. The second reinforcing region 42 is located above the base assembly 200 and is correspondingly provided between the child's buttocks and back to improve the structural strength at the turning points of the seat body 40.

[0089] like Figures 7 to 11As shown, the first reinforcing region 41 has a through-hole 411. Along the first direction a, a plurality of second reinforcing ribs 413 are provided on the side of the through-hole 411 near the first support plate 45. The plurality of second reinforcing ribs 413 are spaced apart along the third direction c. The spaced arrangement of the plurality of second reinforcing ribs 413 along the third direction c helps to improve the connection strength between the first support plate 45 and the seat body 40, and also improves the structural strength of the through-hole 411, thereby contributing to the local strength of the seat body 40 and mitigating the problem of localized fracture of the seat body 40 during impact testing.

[0090] Specifically, in the first reinforced region 41, a tubular structure 412 is provided below the through-hole 411 along the first direction a. The tubular structure 412 helps to further improve the structural strength of the through-hole 411. Simultaneously, multiple second reinforcing ribs 413 are provided below the through-hole 411, spaced apart along the third direction c, to further improve the structural strength of the tubular structure 412, thereby enhancing the structural strength of the first reinforced region 41. Optionally, along the third direction c, two of the multiple second reinforcing ribs 413 located at both ends are provided with extension structures 414. The extension structures 414 extend along the first direction a and connect to the top of the seat body 40, thereby improving the structural strength of the first reinforced region 41 and ensuring the structural strength of the through-hole 411. Simultaneously, a second reinforcing transverse rib 415 is provided below the tubular structure 412, and the second reinforcing transverse rib 415 passes through the multiple second reinforcing ribs 413 and extends along the third direction c, further enhancing the structural strength of the first reinforced region 41.

[0091] like Figure 10 and Figure 12 As shown, the second reinforcing region 42 has three first reinforcing transverse ribs 421, which are spaced apart along a first direction a, dividing the second reinforcing region 42 into a first part 43 and a second part 44. In this embodiment, along a third direction c, slide rails 50 are respectively provided at opposite ends of the second reinforcing region 42. The slide rails 50 cooperate with the three first reinforcing transverse ribs 421, so that the second reinforcing region 42 forms two groove structures, namely the first part 43 and the second part 44. At the same time, a second reinforcing rib 423 is provided in the first part 43, and a third reinforcing rib 424 is provided in the first part 43. The cooperation between the grooves and the reinforcing ribs helps to further improve the structural strength of the second reinforcing region 42. Optionally, the third reinforcing rib 424 and the second reinforcing rib 423 have different shapes. This arrangement helps to further improve the structural strength of the second reinforcing region 42.

[0092] It needs to be further understood that, from the first reinforcing region 41 to the second reinforcing region 42, the second part 44 and the first part 43 are arranged sequentially, and the area of ​​the first part 43 is smaller than the area of ​​the second part 44. That is, at this time, the second part 44 is closer to the first support plate 45. By adjusting the areas of the first part 43 and the second part 44, the structural strength of the second reinforcing region 42 can be adjusted according to the actual situation, thereby making the seat body 40 more adaptable. At the same time, the third reinforcing rib 424 helps to improve the structural strength of the second part 44.

[0093] like Figure 8 , Figure 10 and Figure 12 As shown, the second reinforcing rib 423 is V-shaped, while the third reinforcing rib 424 is X-shaped. This arrangement effectively improves the structural strength of the first part 43 and the second part 44, thereby improving the structural strength of the second reinforced region 42. In this embodiment, the second part 44 also has two reinforcing longitudinal ribs 422. The two reinforcing longitudinal ribs 422, in conjunction with the two slide rails 50, divide the second part 44 into a first reinforcing groove 441, a mounting groove 442, and a second reinforcing groove 443 arranged sequentially along a third direction c. Each of the first reinforcing groove 441 and the second reinforcing groove 443 is provided with multiple third reinforcing ribs 424 arranged sequentially along a third direction c, thereby improving the structural strength of the first reinforcing groove 441 and the second reinforcing groove 443, and thus improving the structural strength of the second part 44.

[0094] It should be noted that, in this embodiment, the mounting groove 442 is provided with a mounting hole 426, and a plurality of fourth reinforcing ribs 425 extending in different directions are provided on the circumferential edge of the mounting hole 426. Each fourth reinforcing rib 425 is either connected to the first reinforcing transverse rib 421 or to the reinforcing longitudinal rib 422, thereby improving the structural strength of the mounting groove 442 and thus improving the structural strength of the second reinforcing region 42.

[0095] like Figure 7 , Figure 8 , Figure 13 and Figure 14As shown, the child safety seat 1000 also includes a base assembly 200, which is disposed on the side of the seat body 40 away from the headrest assembly 300 along the first direction a. A sliding groove 71 is provided on the side of the base assembly 200 facing the seat body 40, and a slide rail 50 adapted to the sliding groove 71 is provided on the side of the seat body 40 facing the base assembly 200 along the first direction a, so that the seat body 40 can be movably disposed on the base assembly 200. The slide rail 50 is adapted to be accommodated in the sliding groove 71, and the sliding of the seat body 40 on the base assembly 200 is realized by a control structure. The control structure can adopt existing structures, thereby realizing the adjustable position of the seat body 40 on the base assembly 200; this application does not impose any limitations on this.

[0096] In this embodiment, the base assembly 200 includes an upper base cover 70 and a lower base cover 80. The lower base cover 80 is used to connect with the ground or a car seat. The upper base cover 70 is positioned above the lower base cover 80, and a sliding groove 71 is provided on the side of the upper base cover 70 facing away from the lower base cover 80. There are two sliding grooves 71, which are spaced apart along a third direction c. Correspondingly, a slide rail portion 50 is provided on the portion of the seat body 40 corresponding to the base assembly 200. The slide rail portion 50 is located on the side of the seat body 40 facing the base assembly 200. Optionally, a roller 72 is provided at the bottom of the sliding groove 71. When the seat body 40 is connected to the upper base cover 70, the roller 72 abuts against the slide rail portion 50 to reduce the sliding friction between the slide rail portion 50 and the sliding groove 71 of the seat body 40, improve the smoothness of seat angle adjustment, and enhance the convenience of adjusting the seat body 40.

[0097] like Figure 13 As shown, two rollers 72 are provided, and along the second direction b, the two rollers 72 are respectively located at opposite ends of the sliding groove 71. By providing two rollers 72, the sliding friction between the slide rail portion 50 of the seat body 40 and the sliding groove 71 is further reduced. At the same time, since the rollers 72 abut against the slide rail portion 50 when the seat body 40 is connected to the base cover 70, the rollers 72 have a supporting force to support the slide rail portion 50, thereby helping to improve the installation effect of the seat body 40.

[0098] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
