[0033] It should be noted that the end of the base assembly 1 with the upper support part 121 and the lower support part 111 is the rear end, and the end opposite to the upper support part 121 and the lower support part is the front end.

[0034] According to an embodiment of the present invention, the child safety seat 100 enhances the structural strength of the entire base assembly 1 by providing a base bracket 13 between the upper base cover 12 and the lower base cover 11 of the base assembly 1, thereby improving the reliability of the base assembly 1. Furthermore, a lower cover decorative cover 15 is provided below the lower base cover 11, which improves the appearance and prevents scratches on the vehicle seat. Additionally, a rear cover 14 is provided behind the lower support portion 111, which, together with the lower support portion 111, defines an open storage slot 141 at the top, which can be used to store items such as instruction manuals, facilitating user operation.

[0035] In some embodiments of this utility model, such as Figure 3 As shown, the upper surface of the base cover 11 has a plurality of spaced or intersecting reinforcing ribs 113, which can enhance the structural strength of the base cover 11 and further improve the structural strength of the base assembly 1.

[0036] In some embodiments of this utility model, such as Figure 4 As shown, the rear surface of the lower support portion 111 has a forward-recessed groove 112, and the rear cover 14 is located within the groove 112. Furthermore, the rear cover 14 does not protrude beyond the rear surface of the lower support portion 111. Therefore, when the child safety seat 100 is installed on the vehicle seat, the rear surface of the lower support portion 111 can abut against the backrest of the vehicle seat to support the child safety seat 100, preventing the rear cover 14 from protruding beyond the rear surface of the lower support portion 111 and abutting against the backrest of the vehicle seat, thus avoiding a decrease in the reliability of the child safety seat 100's fixation.

The support rod 133, the support rod 132, and the support body 131 form a triangular support structure.

[0039] The bracket rod 133, the support and the bracket body 131 form a triangular support mechanism, which can enhance the structural strength and reliability of the entire base bracket 13, thereby better enhancing the structural strength and reliability of the base assembly 1, and thus improving the reliability of the child safety seat 100.

[0040] The cavity formed between the upper support portion 121 and the lower support portion 111 enhances the overall structural strength of the combined structure. Furthermore, the upper end of the support rod 132 extends between the upper support portion 121 and the lower support portion 111, further strengthening the overall structural strength of the combined structure. This enhances the reliability of the support for the child safety seat 100 when the lower support portion 111 abuts against the backrest of the vehicle seat, thereby improving the reliability of the child safety seat 100's fixation.

[0041] exist Figure 5 and Figure 6In the example shown, both the support rod 133 and the support rod 132 are located at the rear end of the support body 131. The support rod 133 is located in front of the support rod 132. Both the support rod 132 and the support rod 133 are inclined backward in the direction from bottom to top, and the inclination angle of the support rod 132 is smaller than that of the support rod 133. The lower end of the support rod 132 is connected to the rear end of the support body 131. The lower end of the support rod 133 is connected to the support body 131 and is located in front of the support rod 132. The upper end of the support rod 133 is connected to the support rod 132 and is spaced apart from the support body 131.

[0042] Optionally, both the support rod 132 and the bracket rod 133 can be tubular structures. Specifically, the support rod 132 and the bracket rod 133 can be square tube structures. Of course, this utility model is not limited to these structures. The support rod 132 and the bracket rod 133 can also be round tubes, elliptical tubes, or other polygonal tubes.

[0043] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the support body 131 includes a base rod 1311, which is a U-shaped rod with an open rear end. The base rod 1311 has two straight rods 1312 extending in the front-rear direction of the base assembly 1 and a bent rod 1313 connected between the two straight rods 1312. There are two support rods 132, which are respectively connected to the rear ends of the two straight rods 1312. There are two support rods 133, which are respectively connected to the two straight rods 1312 and connected to the support rods 132 on the same side.

[0044] It is understood that two straight rods 1312 extend along the front-rear direction of the base assembly 1 and are spaced apart along the left-right direction of the base assembly 1. The two ends of the bent rod 1313 are connected to the front ends of the two straight rods 1312. There are two support rods 132, and the lower ends of the two support rods 132 are respectively connected to the rear ends of the two straight rods 1312. There are two bracket rods 133, and the two bracket rods 133 are respectively connected to the rear ends of the two straight rods 1312 and located in front of the corresponding support rods 132. The upper ends of the two bracket rods 133 are respectively connected to the support rods 132 on the same side. The base rod 1311, the two bracket rods 133 and the two support rods 132 together form two triangular support structures, which can further improve the structural strength and reliability of the base bracket 13, and at the same time simplify the structure and processing technology of the bracket body 131.

[0045] Furthermore, such as Figure 5 and Figure 6As shown, the support body 131 also includes connecting rods 1314, which extend along the left-right direction of the base assembly 1. Both ends of the connecting rods 1314 in the length direction are connected to two straight rods 1312, and multiple connecting rods 1314 are spaced apart along the front-back direction of the base assembly 1. Thus, the connecting rods 1314 enhance the structural strength and reliability of the base rods 1311, further strengthening the structural strength and reliability of the base support 13.

[0046] exist Figure 5 and Figure 6 In the example shown, there are two connecting rods 1314 along the front and rear direction of the base assembly 1. This facilitates the assembly of parts on the base bracket 13, improves the structural strength of the base bracket 13, simplifies the structure of the base bracket 13, and improves production efficiency.

[0047] Optionally, the base rod 1311 and the connecting rod 1314 are tubular structures. Specifically, the base rod 1311 is a square tube structure and the connecting rod 1314 is an oblong tube structure. Of course, this utility model is not limited to this. The base rod 1311 and the connecting rod 1314 can also be tubular structures with other cross-sectional shapes.

[0048] In some embodiments of this utility model, such as Figure 7 and Figure 9 As shown, the child safety seat 100 also includes a seat base cover 2 and a seat body 3. The seat base cover 2 is rotatably mounted above the base bracket 13 about a vertically extending axis of rotation, and the seat body 3 is movably mounted above the seat base cover 2 along the front-rear direction of the seat body 3. This allows for adjustment of the orientation and tilt angle of the seat body 3.

[0049] For example, after the base assembly 1 is fixed to the vehicle seat, the seat base cover 2 and the seat body 3 on it can be rotated synchronously by rotating the seat base cover 2. This allows the seat body 3 to be positioned facing forward or backward, meeting different user needs. Additionally, the seat body 3 can be slid back and forth relative to the seat base cover 2 to adjust its tilt angle, thereby adjusting the child's sitting posture and meeting different user needs.

[0050] It should be noted that the fore-aft direction of the seat body 3 is based on the direction in which the child sits in the child safety seat 100. The front side of the child is the front side of the seat body 3, and the rear side of the child is the rear side of the seat body 3. When the seat body 3 is facing forward, the front side of the seat body 3 is the same as the front side of the base assembly 1. When the seat body 3 is facing backward, the front side of the seat body 3 is opposite to the front side of the base assembly 1.

[0051] In a specific example of this utility model, such as Figures 7-9 As shown, the seat base cover 2 has a sliding rod 24 extending along the left-right direction of the seat body 3. Multiple sliding rods 24 can be spaced apart along the front-back direction of the seat body 3. Sliding grooves 31 extending along the front-back direction of the seat body 3 are provided on the left and right sides below the seat body 3, with the two ends of the sliding rods 24 respectively located in the sliding grooves 31 on both sides. Alternatively, when there are multiple sliding rods 24, multiple sliding grooves 31 can be provided on one side of the seat body 3 in the left-right direction, with each sliding groove 31 corresponding to a different sliding rod 24. The sliding rods 24 slide within the sliding grooves 31, allowing the seat body 3 to slide relative to the seat base cover 2 along the front-back direction of the seat body 3.

[0052] In a specific example of this utility model, such as Figures 7-9 As shown, the base bracket 13 of the base assembly 1 is provided with a first rotating part 17, and the seat cover 2 is provided with a second rotating part 25 that cooperates with the first rotating part 17. The first rotating part 17 is sleeved on the outside of the second rotating part 25 or the second rotating part 25 is sleeved on the outside of the first rotating part 17, so that the first rotating part 17 and the second rotating part 25 can rotate relative to each other, thereby realizing the rotation of the seat cover 2 relative to the base assembly 1.

[0053] In some embodiments of this utility model, such as Figure 10 As shown, the upper side of the seat base cover 2 has a recess 21, and the bottom wall of the recess 21 is provided with a reinforcing structure 22. This can enhance the strength of the seat base cover 2, prevent the two ends of the seat base cover 2 from warping up after being pressed, thus affecting the smoothness of the seat body 3 sliding along the seat base cover 2 and ensuring the smoothness of the seat back angle adjustment.

[0054] Furthermore, such as Figure 10 As shown, the reinforcing structure 22 includes side reinforcing ribs 221 and connecting ribs 222. There are two side reinforcing ribs 221, which are respectively located on both sides of the seat bottom cover 2 along the left and right direction of the seat body 3. The side reinforcing ribs 221 include an outer reinforcing wall 2211, an inner reinforcing wall 2212 and a reinforcing rib 2213. The outer reinforcing wall 2211 and the inner reinforcing wall 2212 extend along the front and rear direction of the seat body 3 and are spaced apart along the left and right direction of the seat body 3 to form reinforcing grooves 2214. The reinforcing ribs 2213 are located in the reinforcing grooves 2214 and are connected to the outer reinforcing wall 2211 and the inner reinforcing wall 2212 at both ends respectively. The connecting ribs 222 extend along the left and right direction of the seat body 3 and are located between the two side reinforcing ribs 221 and are connected to the two side reinforcing ribs 221 at both ends respectively. This can enhance the strength of the seat bottom cover 2, prevent the two ends of the seat bottom cover 2 from lifting up after being pressed, thus ensuring the smoothness of the seat body 3 sliding along the seat bottom cover 2 and guaranteeing the smoothness of the seat back angle adjustment.

[0055] Optionally, the thickness of at least one of the outer reinforcing wall 2211, inner reinforcing wall 2212, reinforcing rib 2213, and connecting rib 222 is 2mm-3mm. This can enhance the structural strength of the outer reinforcing wall 2211, inner reinforcing wall 2212, reinforcing rib 2213, and connecting rib 222, thereby enhancing the strength of the seat base cover 2, preventing the ends of the seat base cover 2 from warping up under pressure, thus affecting the smoothness of the seat body 3 sliding along the seat base cover 2, and ensuring the smoothness of the seat back angle adjustment.

[0056] For example, the thickness of the outer reinforcing wall 2211, the inner reinforcing wall 2212, the reinforcing ribs 2213 and the connecting ribs 222 can be 2.3mm, 2.5mm, 2.7mm or 2.9mm, etc.

[0057] In some examples of this utility model, such as Figure 10 As shown, the reinforcing ribs 2213 are multiple sets spaced apart along the front-rear direction of the seat body 3, each set including two reinforcing ribs 2213, which are arranged in a crisscross pattern. This further enhances the structural strength of the side reinforcing ribs 221 and the strength of the seat bottom cover 2, preventing the ends of the seat bottom cover 2 from warping under pressure and thus ensuring the smoothness of the seat body 3 sliding along the seat bottom cover 2, and guaranteeing the smoothness of the seat back angle adjustment.

[0058] In some embodiments of this utility model, such as Figures 11-13 As shown, for reference Figure 5 and Figure 9 Two locking pieces 16 are connected to the upper part of the base bracket 13. The two locking pieces 16 are located on opposite sides of the rotation axis of the seat base cover 2 in the front-back direction. The edge of the locking piece 16 away from the rotation axis of the seat base cover 2 extends along the circumferential direction of the rotation axis of the seat base cover 2 and has a downwardly extending first flange 161. Two connecting pieces 23 are connected to the lower surface of the seat base cover 2. The two connecting pieces 23 are located on opposite sides of the rotation axis of the seat base cover 2 in the front-back direction of the seat body 3. The edge of the connecting piece 23 near the rotation axis of the seat base cover 2 extends along the circumferential direction of the rotation axis of the seat base cover 2 and has an upwardly extending second flange 231. The second flange 231 is adapted to be located inside the first flange 161 in the radial direction along the rotation axis of the seat base cover 2.

[0059] When the seat body 3 is positioned forward and backward, the connecting piece 23 and the locking piece 16 on the same side of the base assembly 1 in the front-back direction cooperate. The second flange 231 is located inside the first flange 161 in the radial direction along the rotation axis of the seat bottom cover 2. The first flange 161 and the second flange 231 cooperate to limit the seat bottom cover 2 in the front-back direction, ensuring the reliability of the seat bottom cover 2 fixed on the base assembly 1, thereby ensuring the reliability of the seat body 3 fixed.

[0060] In addition, the side edge of the locking piece 16 opposite to the rotation axis of the seat base cover 2 extends along the circumferential direction of the rotation axis of the seat base cover 2, and the corresponding first flange 161 extends along the circumferential direction of the rotation axis of the seat base cover 2. The side edge of the connecting piece 23 close to the rotation axis of the seat base cover 2 extends along the circumferential direction of the rotation axis of the seat base cover 2, and the corresponding second flange 231 extends along the circumferential direction of the rotation axis of the seat base cover 2. This can prevent the first flange 161 and the second flange 231 from interfering when the seat base cover 2 rotates relative to the base assembly 1, and ensure the smooth rotation of the seat base cover 2 relative to the base assembly 1.

[0061] Optionally, such as Figure 5 As shown, two locking pieces 16 are respectively mounted on the two connecting rods 1314 of the base bracket 13.

[0062] In some embodiments of this utility model, the seat body 3 can be adjusted in multiple positions relative to the seat bottom cover 2. For example, the seat body 3 can be adjusted in 5 positions relative to the seat bottom cover 2.

[0063] In some embodiments of this utility model, the child safety seat 100 further includes a headrest assembly 4, which is located at the upper front end of the seat body 3. The headrest assembly 4 is adjustable in the vertical direction to meet the needs of children of different sizes. For example, the headrest assembly 4 has multiple height positions, such as six, along the vertical direction of the seat body 3, and the headrest assembly 4 can be fixed at any of these height positions.

[0064] In some embodiments of this utility model, such as Figure 1 As shown, the child safety seat 100 also includes a side impact protection structure 7. At least one side of the seat body 3 is provided with the side impact protection structure 7, which protrudes from the seat body 3. When the child safety seat 100 is fixed to the vehicle, in the event of a collision, the side impact protection structure 7 near the door first collides with the vehicle sidewall or door, providing a buffering effect. Then, the seat body 3 collides with the vehicle sidewall or door, thus better protecting the child.

[0065] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the rear end of the base assembly 1 is provided with an ISOFIX fixing structure 6 extending backward. There are two ISOFIX fixing structures 6 spaced apart along the left and right directions of the base assembly 1. The ISOFIX fixing structures 6 can be extended and retracted along the front and rear directions of the base assembly 1 to meet different installation requirements.

[0066] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the child safety seat 100 also includes a support foot 5, which extends in the vertical direction. The upper end of the support foot 5 is connected to the base assembly 1, specifically to the base bracket 13 of the base assembly 1. The lower end of the support foot 5 is adapted to support the floor in front of the vehicle seat, thereby improving the reliability of the child safety seat 100 and preventing the child safety seat 100 from tilting forward.

[0067] Among them, the height of the support foot 5 is adjustable in the vertical direction to adapt to different vehicles, thereby better securing the child safety seat 100.

[0068] In some embodiments of this utility model, a display module is provided at the upper end of the support foot 5. The display module can display whether the seat bottom cover 2 has been rotated into place, whether the tilt angle of the seat body 3 has been adjusted to the correct position, and whether the support foot 5 is supported on the vehicle floor, etc. The display information can be presented in the form of a color card.
