Description

Technical Field

[0001] The utility model relates to the technical field of infant products, in particular to a child seat. Background Art

[0002] A child safety seat is a seat designed for children of different weights (or ages) and installed in a car to effectively improve the safety of children in a car. For example, when the car brakes suddenly or collides with the front, the child safety seat can reduce the impact on the child and effectively prevent the child's body from moving forward rapidly, thus avoiding a secondary collision; when the car collides with the rear, the backrest and headrest of the child safety seat can support the child's body and head, thus preventing the child's neck from being injured due to rapid backward movement; when the car collides with the side, the side impact protection device of the child safety seat can provide side impact protection for the child in the event of a side impact, thus achieving all-round protection for the child.

[0003] However, since the side impact protection device of the child safety seat is usually protruding, so that it can effectively play a side impact buffering protection role, and the side impact protection device of the child safety seat is generally fixed and cannot be folded, the overall size of the child safety seat is relatively large. When the child safety seat is packed and shipped, a freight box with relatively large capacity and volume is required to pack a child safety seat. In this way, more freight vehicles are needed to transport the child safety seat, resulting in high transportation costs when shipping the child safety seat. Utility Model Content

[0004] The main purpose of the utility model is to provide a child seat, aiming to solve the technical problem that the side impact protection device of the existing child safety seat cannot be folded, resulting in a relatively large overall volume of the child safety seat and a relatively high transportation cost.

[0005] To achieve the above object, the utility model provides a child seat, comprising:

[0006] A seat body, the seat body comprising a wing portion, the wing portion comprising an outer side wall;

[0007] A side impact protection block, the side impact protection block is movably connected to the side wing portion, the side impact protection block is configured to be able to move to a first position and a second position relative to the side wing portion, and the size of the side impact protection block protruding from the outer side wall when the side impact protection block is in the first position is smaller than the size of the side impact protection block protruding from the outer side wall when the side impact protection block is in the second position;

[0008] A stopper portion is provided on the side impact protection block, and when the side impact protection block is in the first position, the stopper portion abuts against the side wing portion.

[0009] In the above embodiment, a child seat is provided that facilitates folding of the side impact protection block. The side impact protection block is movably connected to the side wing portion, so that the side impact protection block can move freely between a first position and a second position. For example, the first position can be a position when the side impact protection block is completely folded in the side wing portion, and the second position can be a position when the side impact protection block is unfolded from the side wing portion and is in normal use. When the child seat needs to be packed and transported, the side impact protection block is folded at this time so that the side impact protection block is in the first position, which can reduce the size of the side impact protection block protruding from the outer wall, and even the side impact protection block can be completely embedded in the outer wall, which is conducive to reducing the overall volume of the child seat, and conveniently using a box with a smaller capacity and volume to pack the child seat, so that a freight vehicle can load more boxes of child seats, reducing the cost of the child seat during freight. When the child seat is used normally, the side impact protection block is unfolded at this time so that the side impact protection block is in the second position, which can increase the size of the side impact protection block protruding from the outer wall, so as to effectively play the role of buffer protection of the side impact protection block.

[0010] Furthermore, the blocking portion can be protrudingly arranged on the side impact protection block. When the side impact protection block is in the first position, that is, when the side impact protection block is folded in the side wing portion, the blocking portion can be used to clamp the side impact protection block in the side wing portion, thereby achieving stable positioning of the side impact protection block in the side wing portion and preventing the side impact protection block from unfolding from the side wing portion due to loose clamping, thereby affecting the packing effect of the child seat.

[0011] In addition, when the side impact protection block is in the second position, that is, when the side impact protection block is deployed from the side wing portion, and when the side impact protection block is hit from the side, under the action of the impact force, the side impact protection block will move from the second position to the first position and gradually retract into the side wing portion. During the movement of the side impact protection block, the stopper portion also has the function of preventing the side impact protection block from being embedded in the side wing portion. Therefore, when the child seat is hit, on the one hand, the side impact protection block itself can play a buffering and protective role, and on the other hand, the stopper portion can also play a certain buffering and protective role on the movement of the side impact protection block, which is conducive to achieving the dual protection of the side impact protection block, improving the buffering and protective effect of the side impact protection block, and improving the safety performance of the child seat.

[0012] In some embodiments, the shifting portion is connected to the side impact protection block via an elastic portion, and the elastic portion can drive the shifting portion to move to a third position and a fourth position relative to the side impact protection block;

[0013] Wherein, when the side impact protection block is in the first position, the blocking portion is in the third position and the blocking portion abuts against the outer side wall; when the side impact protection block is in the second position, the blocking portion is in the fourth position.

[0014] In the above embodiment, the shifting part is connected to the side impact protection block through the elastic part, and flexible movement between the two is achieved, which effectively improves the response speed and adaptability of the side impact protection block. When the side impact protection block is in the first position, the shifting part is automatically moved to the third position under the drive of the elastic part and abuts against the outer side wall, thereby enhancing the positioning stability of the side impact protection block; and when the side impact protection block is turned to the second position, the shifting part is quickly moved to the fourth position under the drive of the elastic part.

[0015] In some embodiments, the side impact protection block is rotatably connected to the side wing portion via a hinge portion, and when the side impact protection block rotates between the first position and the second position, the hinge portion has a folded state and an unfolded state;

[0016] Wherein, when the side impact protection block is in the first position, the hinged portion is in the folded state; when the side impact protection block is in the second position, the hinged portion is in the unfolded state.

[0017] In the above embodiment, the side impact protection block is rotatably connected to the side wing portion through the hinge portion, which has a simple structure, stable connection, and sensitive movement. The hinge portion has a folded state and an unfolded state, which is conducive to the side impact protection block protruding from the outer side wall and reducing the space occupied by the hinge portion in the side wing portion.

[0018] In some embodiments, the side impact protection block is connected to a fixing portion, the hinge portion is provided between the fixing portion and the side impact protection block, one end of the hinge portion is connected to the fixing portion, and the other end of the hinge portion is connected to the side impact protection block;

[0019] Wherein, the fixing portion is connected to the wing portion through a fixing piece.

[0020] In the above embodiment, the side impact protection block is connected to one end of the hinged part, the other end of the hinged part is connected to the fixed part, and the fixed part is connected to the side wing part through a fixing member, which is beneficial to improve the connection stability of the side impact protection block to the side wing part.

[0021] In some embodiments, the hinge portion is provided with a folding groove along the direction of the folding axis, and the folding groove has a first folding surface and a second folding surface which are arranged opposite to each other;

[0022] Wherein, when the hinged portion is in the folded state, the first folding surface moves in a direction approaching the second folding surface; when the hinged portion is in the unfolded state, the first folding surface moves in a direction away from the second folding surface.

[0023] In the above embodiment, the folding groove is provided, which is helpful to reduce the folding tension of the hinge portion when folding, and further helps to improve the positioning stability of the side impact protection block in the side wing portion.

[0024] In some embodiments, a limiting groove is provided in the side wing portion, and a limiting portion is provided in the side impact protection block, the limiting portion is connected to the limiting groove, and the limiting portion can slide in the limiting groove;

[0025] Wherein, when the side impact protection block is in the second position, the limiting portion can abut against the groove wall of the limiting groove to limit the size of the side impact protection block protruding from the side wing portion.

[0026] In the above embodiment, by providing a limiting groove and a limiting portion, when the side impact protection block is in the second position, the limiting portion can abut against the groove wall of the limiting groove, effectively limiting the size of the side impact protection block protruding from the side wing portion, thereby improving the reliability of the side impact protection block in the second position.

[0027] In some embodiments, the side wing portion includes an inner side wall, the inner side wall is provided with a first buffer portion and a second buffer portion along a first direction, the first buffer portion includes a first inert foam structure, a second inert foam structure and a corn cotton structure, the corn cotton structure is provided between the first inert foam structure and the second inert foam structure, and the second buffer portion is a structure made of foam;

[0028] Wherein, the side impact protection block is correspondingly arranged between the first buffer portion and the second buffer portion.

[0029] In the above embodiment, a first buffer portion and a second buffer portion are arranged along a first direction on the inner wall. The first buffer portion is made of an inert foam structure and a corn cotton structure to provide good buffering and dispersion of impact force, while the second buffer portion is made of foam to increase the flexibility of the structure, so that it can effectively absorb and disperse the impact energy during a side collision, thereby ensuring the driving safety of children.

[0030] In addition, the provision of side impact protection blocks further enhances the anti-collision performance of the side wings and reduces the risk of injury caused by collision.

[0031] In some embodiments, a concave portion is provided on a side of the side impact protection block away from the side wing portion, and the concave portion is used to move the side impact protection block from the first position to the second position.

[0032] In the above embodiment, the concave portion facilitates the operation of the side impact protection block, which is conducive to smoothly moving the side impact protection block from the first position to the second position.

[0033] In some embodiments, a rotation angle α of the side impact protection block from the first position to the second position satisfies: 15°≤α≤30°.

[0034] In the above embodiment, the side impact protection block is rotated to a suitable angle to ensure the buffering protection effect of the side impact protection block.

[0035] In some embodiments, the end of the shifting portion close to the side of the wing portion is configured as an arc end surface.

[0036] In the above embodiment, the arc end surface is provided, which is conducive to snapping the shifting portion into the side wing portion, and further facilitates snapping the side impact protection block into the side wing portion. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0076] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0077] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0078] A child safety seat is a seat designed for children of different weights (or ages) and installed in a car to effectively improve the safety of children in a car. For example, when the car brakes suddenly or collides with the front, the child safety seat can reduce the impact on the child and effectively prevent the child's body from moving forward rapidly, thus avoiding a secondary collision; when the car collides with the rear, the backrest and headrest of the child safety seat can support the child's body and head, thus preventing the child's neck from being injured due to rapid backward movement; when the car collides with the side, the side impact protection device of the child safety seat can provide side impact protection for the child in the event of a side impact, thus achieving all-round protection for the child.

[0079] However, since the side impact protection device of the child safety seat is usually protruding, so that it can effectively play a side impact buffering protection role, and the side impact protection device of the child safety seat is generally fixed and cannot be folded, the overall size of the child safety seat is relatively large. When the child safety seat is packed and shipped, a freight box with relatively large capacity and volume is required to pack a child safety seat. In this way, more freight vehicles are needed to transport the child safety seat, resulting in high transportation costs when shipping the child safety seat.

[0080] In order to solve the technical problem that the side impact protection device of the existing child safety seat cannot be folded, resulting in a relatively large overall volume of the child safety seat and a relatively high transportation cost, Figures 1 to 15An embodiment of the utility model provides a child seat, including a seat body 100, a side impact protection block 200 and a stopper 300. The seat body 100 includes a side wing portion 110, and the side wing portion 110 includes an outer side wall 111. The side impact protection block 200 is movably connected to the side wing portion 110. The side impact protection block 200 is configured to be able to move to a first position 1200 and a second position 1300 relative to the side wing portion 110. When the side impact protection block 200 is located at the first position 1200, the size protruding from the outer side wall 111 is smaller than the size protruding from the outer side wall 111 when the side impact protection block 200 is located at the second position 1300. The stopper 300 is arranged on the side impact protection block 200. When the side impact protection block 200 is in the first position 1200, the stopper 300 abuts against the side wing portion 110.

[0081] Specifically, in order to solve the above-mentioned problem, in the present embodiment, a child seat is provided for folding the side impact protection block 200 conveniently. The side impact protection block 200 is movably connected to the side wing portion 110, so that the side impact protection block 200 can move freely between a first position 1200 and a second position 1300. Exemplarily, for example, the first position 1200 can be the position when the side impact protection block 200 is fully folded in the side wing portion 110, and the second position 1300 can be the position when the side impact protection block 200 is unfolded from the side wing portion 110 and in normal use. When the child seat needs to be packed for transportation, the side impact protection block 200 is folded so that the side impact protection block 200 is in the first position 1200, which can reduce the size of the side impact protection block 200 protruding from the outer wall 111, and can even be completely embedded in the outer wall 111, which is conducive to reducing the overall volume of the child seat, and conveniently using boxes with smaller capacity and volume to pack the child seat, so that a freight vehicle can load more boxes of child seats, reducing the cost of freighting child seats. When the child seat is used normally, the side impact protection block 200 is unfolded so that the side impact protection block 200 is in the second position 1300, which can increase the size of the side impact protection block 200 protruding from the outer wall 111, so that the buffer protection function of the side impact protection block 200 is effectively exerted.

[0082] Furthermore, the blocking portion 300 can be protrudingly arranged on the side impact protection block 200. When the side impact protection block 200 is in the first position 1200, that is, when the side impact protection block 200 is folded in the side wing portion 110, the blocking portion 300 can be used to clamp the side impact protection block 200 in the side wing portion 110, thereby achieving stable positioning of the side impact protection block 200 in the side wing portion 110, and preventing the side impact protection block 200 from being unfolded from the side wing portion 110 due to loose clamping, thereby affecting the packing effect of the child seat.

[0083] In addition, when the side impact protection block 200 is in the second position 1300, that is, when the side impact protection block 200 is deployed from the side wing portion 110, and when the side impact protection block 200 is hit from the side, under the action of the impact force, the side impact protection block 200 will move from the second position 1300 to the first position 1200, and gradually retract into the side wing portion 110. During the movement of the side impact protection block 200, the stopper portion 300 also has the function of preventing the side impact protection block 200 from being embedded in the side wing portion 110. Therefore, when the child seat is hit, on the one hand, the side impact protection block 200 itself can play a buffering and protective role, and on the other hand, the stopper portion 300 can also play a certain buffering and protective role on the movement of the side impact protection block 200, thereby facilitating the realization of the double protection of the side impact protection block 200, improving the buffering and protective effect of the side impact protection block 200, and improving the safety performance of the child seat.

[0084] Further, in some embodiments, for example, the outer side wall 111 of the side wing portion 110 may be provided with a mounting groove, and the side impact protection block 200 is connected to the mounting groove. When the side impact protection block 200 is in the first position 1200, the side impact protection block 200 may be entirely embedded in the mounting groove, and at this time, the stopper portion 300 may abut against the groove wall of the mounting groove to achieve stable positioning of the side impact protection block 200. When the side impact protection block 200 is in the second position 1300, the side impact protection block 200 may be deployed from the mounting groove to achieve buffer protection of the side impact protection block 200.

[0085] In some embodiments, reference Figure 2 , Figure 3 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 The stopper 300 is connected to the side impact protection block 200 through an elastic part 400 (for example, the elastic part 400 may be a spring), and the elastic part 400 can drive the stopper 300 to move to a third position 1400 and a fourth position 1500 relative to the side impact protection block 200. When the side impact protection block 200 is in the first position 1200, the stopper 300 is in the third position 1400, and the stopper 300 abuts against the outer side wall 111; when the side impact protection block 200 is in the second position 1300, the stopper 300 is in the fourth position 1500.

[0086] Specifically, in the present embodiment, a driving mode of the stopper 300 is provided, and the stopper 300 is connected to the side impact protection block 200 through the elastic part 400, so that a flexible connection is achieved between the stopper 300 and the side impact protection block 200, so that the stopper 300 is conveniently used to realize the positioning of the side impact protection block 200 in the first position 1200. When the side impact protection block 200 is in the first position 1200, since the side impact protection block 200 protrudes from the outer side wall 111 in the first position 1200, the side impact protection block 200 is at least partially or completely embedded in the side wing part 110, and the stopper 300 is squeezed between the side impact protection block 200 and the side wing part 110, and the elastic part 400 is compressed, and at the same time, the elastic part 400 has a tendency to restore elastic deformation, so that the stopper 300 is pressed against the side wing part 110, so as to realize the stable positioning of the side impact protection block 200. When the side impact protection block 200 is in the second position 1300, since the side impact protection block 200 protrudes from the outer wall 111 to a greater extent in the second position 1300, the side impact protection block 200 can be unfolded from the side wing portion 110. At this time, the blocking portion 300 is no longer squeezed between the side impact protection block 200 and the side wing portion 110, and the elastic portion 400 will be released. Driven by the elastic portion 400, the blocking portion 300 will return to its initial state.

[0087] In addition, when the side impact protection block 200 is subjected to impact force, it will gradually move from the second position 1300 to the first position 1200. When the side impact protection block 200 is about to move to the first position 1200, the shifting portion 300 will first contact the outer wall 111 of the side wing portion 110 and continuously squeeze the elastic portion 400. In the process of squeezing the elastic portion 400, it can also play a buffering and protective role, thereby helping to improve the lateral buffering and protection effect of the child seat.

[0088] It can be understood that the third position 1400 is the position where the elastic part 400 is compressed and the position where the stopper 300 abuts against the outer wall 111. The fourth position 1500 is the position where the elastic part 400 is released and the position where the stopper 300 is in a natural state.

[0089] In some embodiments, reference Figure 12 to Figure 14 The side impact protection block 200 is rotatably connected to the side wing portion 110 through a hinge portion 500 (for example, the hinge portion 500 may be a hinge leaf). When the side impact protection block 200 rotates between the first position 1200 and the second position 1300, the hinge portion 500 has a folded state and an unfolded state. When the side impact protection block 200 is in the first position 1200, the hinge portion 500 is in the folded state; when the side impact protection block 200 is in the second position 1300, the hinge portion 500 is in the unfolded state.

[0090] Specifically, in the present embodiment, a connection structure of a side impact protection block 200 on the side wing portion 110 is provided, and one end of the side impact protection block 200 is rotatably connected to the side wing portion 110 through a hinge portion 500. When the side impact protection block 200 moves from a first position 1200 to a second position 1300, the side impact protection block 200 gradually unfolds from the side wing portion 110 with the axis of the hinge portion 500 as the rotation axis. When the side impact protection block 200 moves to the second position 1300, the hinge portion 500 is in an unfolded state to adaptively connect the side impact protection block 200 to prevent the side impact protection block 200 from detaching from the side wing portion 110 during rotation. When the side impact protection block 200 moves from the second position 1300 to the first position 1200, the side impact protection block 200 gradually retracts into the side wing portion 110 with the axis of the hinge portion 500 as the rotation axis. When the side impact protection block 200 moves to the first position 1200, the hinge portion 500 is in a folded state to reduce the space occupied by the hinge portion 500 in the side wing portion 110, thereby making the structure in the side wing portion 110 more compact.

[0091] In some embodiments, reference Figures 2 to 5 ,as well as Figure 12 to Figure 14 , the side impact protection block 200 is connected with a fixing portion 600, a hinge portion 500 is arranged between the fixing portion 600 and the side impact protection block 200, one end of the hinge portion 500 is connected to the fixing portion 600, and the other end of the hinge portion 500 is connected to the side impact protection block 200. Among them, the fixing portion 600 is connected to the side wing portion 110 through a fixing piece 700. Exemplarily, for example, the fixing portion 600 can be a fixing strip to ensure that the fixing portion 600 can provide sufficient installation space for the hinge portion 500, and the connection side of the fixing portion 600 and the hinge portion 500 can be reduced to a plane shape to facilitate the hinge portion 500 to fold into place and reduce the elastic force of the hinge portion 500 after folding. The fixing piece 700 can be a screw, and fixing holes can be arranged at both ends of the fixing portion 600, and the fixing portion 600 is connected and positioned on the side wing portion 110 by screws passing through the fixing holes.

[0092] Further, preferably, the fixing portion 600 and the fixing piece 700 may be structures made of stainless steel to extend the service life of the fixing portion 600 and the fixing piece 700 .

[0093] In some embodiments, reference Fig.14 The hinge 500 is provided with a folding groove 510 (for example, the folding groove 510 may be a V-shaped groove) along the direction of the folding axis, and the folding groove 510 has a first folding surface 520 and a second folding surface 530 that are arranged opposite to each other. When the hinge 500 is in a folded state, the first folding surface 520 moves toward a direction close to the second folding surface 530; when the hinge 500 is in an unfolded state, the first folding surface 520 moves toward a direction away from the second folding surface 530.

[0094] Specifically, in this embodiment, the folding axis of the hinge 500 is located in the folding groove 510, with the folding axis as the dividing line, the left side of the folding axis is the first folding surface 520, and the right side of the folding axis is the second folding surface 530. When the hinge 500 is in a folded state, the first folding surface 520 and the second folding surface 530 will be folded along the folding axis, and when the hinge 500 is in an unfolded state, the first folding surface 520 and the second folding surface 530 will be unfolded along the folding axis. By providing a folding groove 510 on the hinge 500 and setting the folding axis of the hinge 500 in the folding groove 510, the folding tension between the first folding surface 520 and the second folding surface 530 can be reduced, so that the first folding surface 520 and the second folding surface 530 are easier to fold together, so as to prevent the side impact protection block 200 from being stably positioned in the side wing portion 110 due to the folding tension after the hinge 500 is folded, and avoid the side impact protection block 200 from automatically unfolding due to the folding tension.

[0095] In some embodiments, reference Figure 7 and Fig. 9 The side wing portion 110 is provided with a limiting groove 113, and the side impact protection block 200 is provided with a limiting portion 800, which is connected to the limiting groove 113 and can slide in the limiting groove 113. When the side impact protection block 200 is in the second position 1300, the limiting portion 800 can abut against the groove wall of the limiting groove 113, so as to limit the size of the side impact protection block 200 protruding from the side wing portion 110.

[0096] Specifically, in this embodiment, taking the side impact protection block 200 being rotatably connected to the side wing portion 110 through the hinge portion 500 as an example, the cooperation between the limiting portion 800 and the limiting groove 113 can control the deployment angle of the side impact protection block 200 when it is in the second position 1300, so as to avoid the side impact protection block 200 being deployed too large or too small at the second position 1300, thereby causing the side impact protection block 200 to fail to play a good buffering protection role. When the side impact protection block 200 rotates toward the first position 1200, the limiting portion 800 can move in the limiting groove 113 in the direction away from the outer side wall 111. When the side impact protection block 200 rotates to the first position 1200, the limiting portion 800 can be exactly located at the end of the limiting groove 113 away from the outer side wall 111, so as to ensure that the side impact protection block 200 is not affected from being embedded in the side wing portion 110. When the side impact protection block 200 rotates toward the second position 1300, the limiting portion 800 can move in the limiting groove 113 toward the direction close to the outer wall 111. When the side impact protection block 200 rotates to the second position 1300, the limiting portion 800 can be exactly located at one end of the limiting groove 113 close to the outer wall 111 to limit the side impact protection block 200 from continuing to expand outward, thereby ensuring that the side impact protection block 200 can be at a suitable angle.

[0097] Furthermore, in some embodiments, the limiting groove 113 can be gradually narrowed from an end away from the outer wall 111 to an end close to the outer wall 111, so that when the limiting portion 800 is at an end close to the outer wall 111, it can be clamped in the limiting groove 113, thereby ensuring that the side impact protection block 200 can be stably positioned in the second position 1300.

[0098] In some embodiments, reference Figure 1 and Fig.15 The wing portion 110 includes an inner side wall 112, and the inner side wall 112 is provided with a first buffer portion 900 and a second buffer portion 1000 along a first direction X (for example, the first direction X may be a vertical direction). The first buffer portion 900 includes a first inert foam structure 910, a second inert foam structure 920, and a corn cotton structure 930. The corn cotton structure 930 is provided between the first inert foam structure 910 and the second inert foam structure 920, and the second buffer portion 1000 is a structure made of foam. The side impact protection block 200 is correspondingly provided between the first buffer portion 900 and the second buffer portion 1000.

[0099] Specifically, in this embodiment, when the child seat is hit sideways, in addition to providing a side impact protection block 200 on the outer side wall 111 of the side wing 110 for buffering protection, a flexible portion can also be provided on the inner side wall 112 of the side wing 110 to provide buffering protection for the child's body. Corresponding to the position of the child's head, the inner side wall 112 of the side wing 110 is provided with a relatively soft first buffer portion 900 to ensure effective anti-collision protection for the child's head. Corresponding to the position of the child's shoulder, the inner side wall 112 of the side wing 110 is provided with a relatively hard second buffer portion 1000 to ensure effective strength support for the child's shoulder.

[0100] It should be noted that the above-mentioned “softer” means that the first buffer portion 900 is softer than the second buffer portion 1000, and the above-mentioned “harder” means that the second buffer portion 1000 is harder than the first buffer portion 900. The softness and hardness of the first buffer portion 900 and the second buffer portion 1000 correspond to different body parts of children.

[0101] Furthermore, the first buffer portion 900 adopts the above-mentioned sandwich structure design, which can ensure the softness of the first buffer portion 900 (mainly the first inert foam structure 910 and the second inert foam structure 920 can play an effective buffering role) while ensuring that the first buffer portion 900 has a fireproof function (mainly the corn cotton structure 930 can play a fireproof role).

[0102] Furthermore, the side impact protection block 200 is arranged on the outer wall 111 of the side wing portion 110, and the first buffer portion 900 and the second buffer portion 1000 are arranged on the inner wall 112 of the side wing portion 110. The side impact protection block 200 is spatially arranged between the first buffer portion 900 and the second buffer portion 1000. When a side impact occurs, the outer wall 111 of the side wing portion 110 can buffer the impact force through the side impact protection block 200, and the inner wall 112 of the side wing portion 110 can protect the child from impact through the first buffer portion 900 and the second buffer portion 1000, thereby achieving a double protection effect of the child seat.

[0103] In some embodiments, reference Figure 5 , Fig.12 , Fig.13 and Fig.14 A concave portion 1100 is provided on a side of the side impact protection block 200 away from the side wing portion 110 , and the concave portion 1100 is used to move the side impact protection block 200 from the first position 1200 to the second position 1300 .

[0104] Specifically, in the present embodiment, since the side impact protection block 200 may be completely embedded in the side wing portion 110 when it is in the first position 1200, resulting in a "perfect fit" between the side impact protection block 200 and the side wing portion 110, in order to facilitate the movement of the side impact protection block 200 from the first position 1200 to the second position 1300, a recessed portion 1100 is provided on the side of the side impact protection block 200 away from the side wing portion 110. For example, the recessed portion 1100 may be a groove structure. When the side impact protection block 200 needs to be protruded from the side wing portion 110 to a larger size, the hand is "picked" at the recessed portion 1100, and then an outward force is applied to pull the side impact protection block 200 out of the side wing portion 110, so that the side impact protection block 200 moves to the second position 1300, and the side impact protection block 200 achieves a buffering protection function for the lateral impact force.

[0105] In some embodiments, the rotation angle α of the side impact protection block 200 from the first position 1200 to the second position 1300 satisfies: 15°≤α≤30°. For example, the value of α can be 15°, 20°, 25°, 30°, and so on.

[0106] Specifically, in the present embodiment, the rotation angle of the side impact protection block 200 from the first position 1200 to the second position 1300 is set within the above-mentioned angle range. On the one hand, it can be avoided that the rotation angle of the side impact protection block 200 from the first position 1200 to the second position 1300 is too small (for example, the side impact protection block 200 rotates 5°, 10°, etc.), so that the deployment angle of the side impact protection block 200 is too small, and thus the impact force cannot be well buffered. On the other hand, it can also be avoided that the rotation angle of the side impact protection block 200 from the first position 1200 to the second position 1300 is too large (for example, the side impact protection block 200 rotates 50°, 60°, etc.), so that the deployment angle of the side impact protection block 200 is too large, thereby increasing the overall volume of the child seat. At the same time, the side impact protection block 200 deployed at a large angle also cannot play a good buffering role against the impact force.

[0107] In some embodiments, reference Figure 7 and Fig. 9 The end of the stopper portion 300 close to the side wing portion 110 is set as an arc end surface.

[0108] Specifically, in this embodiment, the end of the stopper 300 close to the side wing 110 is set to a smooth arc end surface. When the side impact protection block 200 moves from the second position 1300 to the first position 1200 and is about to be inserted into the side wing 110, the arc end surface can guide the stopper 300 to prevent the stopper 300 from being blocked when contacting the side wing 110 (for example, if the stopper 300 is close to the side wing 110, the stopper 300 is close to the side wing 110). The end portion on one side of 10 is set as a right-angle end face. When the blocking portion 300 is inserted into the side wing portion 110, a "blocking dead angle" may be formed due to the right-angle end face pressing against the outer wall 111 of the side wing portion 110, thereby forming an obstacle when the blocking portion 300 is inserted into the side wing portion 110) and the blocking portion 300 cannot be smoothly inserted into the side wing portion 110, resulting in the side impact protection block 200 cannot be smoothly embedded in the side wing portion 110, and the side impact protection block 200 cannot be folded.

[0109] It should be noted that other contents of the child seat disclosed in the present utility model can be found in the prior art and will not be described in detail here.

[0110] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
