[0068] See also Figures 1 to 4 , Figure 1 and Figure 2 Schematic diagrams of the appearance of a child safety seat 1 according to the first embodiment of the present invention at different viewing angles. Figure 3FIG. 1 is a partial structural diagram of a child safety seat 1 according to a first embodiment of the present invention. Figure 4 FIG. 1 is a partial cross-sectional schematic diagram of a child safety seat 1 according to a first embodiment of the present invention. Figures 1 to 4 As shown, the child safety seat 11 includes a seat body 11, the seat body 11 includes a seat portion 111, a backrest portion 112 and two structural reinforcements 113, the seat portion 111 includes a first end portion 1111 away from the backrest portion 112 and a second end portion 1112 connected to the backrest portion 112, and the two structural reinforcements 113 are vertically and spaced apart along the backrest portion 112 to increase the structural strength of the seat body 11, thereby resisting a larger impact. The number and location of the structural reinforcements of the present invention are not limited to this embodiment. For example, in another embodiment, the structural reinforcement can be omitted, or there is only one structural reinforcement arranged along the backrest portion.

[0069] Each structural reinforcement 113 includes a first flange 1131, a second flange 1132, a web 1133 and a plurality of ribs 1134. The first flange 1131 is arranged on the backrest portion 112, and the second flange 1132 is substantially arranged in parallel with the first flange 1131. The web 1133 connects the first flange 1131 and the second flange 1132. The first flange 1131, the web 1133 and the second flange 1132 are integrally formed and present a C-shaped structure. The C-shaped structure has a cavity 1135 and a lateral opening 1136. A plurality of ribs 1134 are arranged in the cavity 1135 and connect the first flange 1131, the second flange 1132 and the web 1133.

[0070] Preferably, in this embodiment, the plurality of ribs 1134 can be arranged to form a plurality of triangular structures. This design can not only provide appropriate structural strength to resist a large impact, but also save manufacturing costs, because the material is efficiently arranged at the location of the seat body 11 where the stress is greater. The present invention is not limited to this. For example, in another embodiment, the plurality of ribs can also be arranged to form at least one triangular structure or at least one honeycomb structure. Alternatively, in another embodiment, the plurality of ribs can also be arranged parallel to each other.

[0071] See also Figure 1 , Figure 2 and Figures 5 to 10 , Figure 5 FIG. 1 is a partial structural diagram of the child safety seat 1 according to the first embodiment of the present invention from another perspective. Figure 6 FIG. 1 is a schematic diagram of a portion of the internal structure of a child safety seat 1 according to a first embodiment of the present invention. Figure 7 and Figure 8 Schematic diagram of the child safety seat 1 according to the first embodiment of the present invention when the adjustment foot 12 is located at different positions. Fig. 9 This is a schematic diagram of a child safety seat 1 according to a first embodiment of the present invention when it is arranged forward on a transportation vehicle seat 2. Fig.10 This is a schematic diagram of a child safety seat 1 according to a first embodiment of the present invention when it is placed on a transportation vehicle seat 2 facing backward. Figure 1 , Figure 2 and Figures 5 to 10 As shown, the child safety seat 1 further includes an adjustment foot 12 and a tilting foot 116, the seat body 11 further includes a first support portion 114 and a second support portion 115, the tilting foot 116 is pivotally coupled to the seat body 11, specifically, the tilting foot 116 is pivotally coupled to the seat portion 111, the first support portion 114 is formed on the tilting foot 116 and is located adjacent to the first end 1111 of the seat portion 111 away from the backrest portion 112, the second support portion 115 is formed on the seat portion 111 or the backrest portion 112 and is located adjacent to the second end 1112 where the seat portion 111 and the backrest portion 112 are connected, the adjustment foot 12 includes a third support portion 121, the adjustment foot 12 is pivotally coupled to the tilting foot 116 and can be used as shown in FIG. Figure 8 The forward position shown is similar to Figure 2 The rearward positions are pivotally switched, and the pivoting of the adjustment foot 12 is independent of the pivoting of the tilting foot 116. The present invention is not limited thereto. For example, in another embodiment, the adjustment foot may be movably disposed on the seat body, rather than on the tilting foot.

[0072] Furthermore, the seat body 11 further includes a brake 117 and an elastic member 118. The brake 117 is pivotally disposed on the seat portion 111 to allow or limit the tilting foot 116 to pivot relative to the seat body 11. The elastic member 118 abuts against the brake 117 so that the brake 117 has potential energy to limit the tilting foot 116 from pivoting relative to the seat body 11.

[0073] Preferably, in this embodiment, two first engaging portions 1171 are formed on the brake 117, and a plurality of second engaging portions 1161 are formed on the tilting foot 116. When the two first engaging portions 1171 engage with the corresponding two second engaging portions 1161, the brake 117 limits the tilting foot 116 from pivoting relative to the seat body 11. When the two first engaging portions 1171 are disengaged from the corresponding two second engaging portions 1161, the brake 117 allows the tilting foot 116 to pivot relative to the seat body 11. The elastic member 118 abuts against the brake 117 so that the two first engaging portions 1171 have the potential energy to engage with the corresponding two second engaging portions 1161. However, the present invention is not limited thereto, and any mechanism that allows or limits the tilting foot 116 from pivoting relative to the seat body 11 belongs to the scope of the present invention.

[0074] In addition, the adjustment foot 12 includes two first stop portions 122 to stop the tilting foot 116 so that the adjustment foot 12 is positioned in the forward position, and the tilting foot 116 includes two second stop portions 1162 to stop the adjustment foot 12 so that the adjustment foot 12 is positioned in the rearward position. In this embodiment, each second stop portion 1162 is preferably adjusted in a rotatable manner to adjust the angle of the adjustment foot 12 located in the rearward position. The present invention is not limited to this. For example, in another embodiment, the adjustment foot may include only one first stop portion, and the tilting foot may include only one second stop portion. Alternatively, in another embodiment, the child safety seat may further include an operating member for allowing or limiting the pivoting of the adjustment foot so that the adjustment foot can be positioned at any position between the forward position and the rearward position, and the first stop portion and the second stop portion may be omitted.

[0075] like Fig. 9 As shown, when the user wants to install the child safety seat 1 on the transportation carrier seat 2 facing forward, the adjustment foot 12 can be switched to the rearward position, so that the first support portion 114 and the third support portion 121 abut against the transportation carrier seat 2 to support the child safety seat 1 installed forward on the transportation carrier seat 2. In other words, when the child safety seat 1 is installed on the transportation carrier seat 2 in a forward manner, the adjustment foot 12 is in the rearward position, and the adjustment foot 12 and the tilting foot 116 respectively abut against the transportation carrier seat 2. At this time, the tilt angle of the child safety seat 1 installed forward can be adjusted by pivoting the tilting foot 116 and / or the adjustment foot 12.

[0076] It is worth noting that when the first support portion 114 and the third support portion 121 abut against the transportation carrier seat 2 to support the child safety seat 1 installed forward on the transportation carrier seat 2, the projection of the center of gravity CG of the child safety seat 1 along the gravity direction G on the support line (e.g., a straight line on the support surface of the transportation carrier seat) is located between the projection of the first support portion 114 along the gravity direction G on the support line and the projection of the third support portion 121 along the gravity direction G on the support line. In other words, when the child safety seat 1 is installed on the transportation carrier seat 2 in a forward manner, the projection of the center of gravity CG of the child safety seat 1 along the gravity direction G on the transportation carrier seat 2 is located between the contact point between the tilting foot 116 and the transportation carrier seat 2 and the contact point between the adjusting foot 12 and the transportation carrier seat 2. This design can ensure that the child safety seat 1 installed forward can be stably supported by the first support portion 114 and the third support portion 121.

[0077] Furthermore, if Fig. 9As shown, in this embodiment, when the child safety seat 1 is installed forward on the vehicle seat 2, the pivot point P between the tilting foot 116 and the seat body 11 and the center of gravity CG of the child safety seat 1 are preferably arranged along the gravity direction G, and the pivot point P between the tilting foot 116 and the seat body 11 is located below the center of gravity CG of the child safety seat 1. This design can prevent the child safety seat 1 from tipping over due to gravity when the first engaging portion 1171 and the second engaging portion 1161 are accidentally disengaged.

[0078] like Fig.10 As shown, when the user wants to install the child safety seat 1 on the transportation vehicle seat 2 facing backward, the adjustment foot 12 can be switched to the forward position so that the second support portion 115 and the third support portion 121 abut against the transportation vehicle seat 2 to support the child safety seat 1 installed on the transportation vehicle seat 2 facing backward. In other words, when the child safety seat 1 is installed on the transportation vehicle seat 2 facing backward, the adjustment foot 12 is in the forward position, and one end of the adjustment foot 12 and the seat body 11 abut against the transportation vehicle seat 2 respectively, while the tilting foot 116 is located above the transportation vehicle seat 2 and does not contact the transportation vehicle seat 2. At this time, since the adjustment foot 12 is adjusted by Figure 8 The first stop portion 112 shown abuts against the tilting foot 116 , ie, the tilting foot 116 rests on the adjusting foot 112 , so the tilting angle of the rearward-mounted child safety seat 1 can be adjusted by pivoting the tilting foot 116 and the adjusting foot 112 .

[0079] It is worth noting that when the second support portion 115 and the third support portion 121 abut against the transportation carrier seat 2 to support the child safety seat 1 installed on the transportation carrier seat 2 facing backward, the projection of the center of gravity CG of the child safety seat 1 along the gravity direction G on the support line is located between the projection of the second support portion 115 along the gravity direction G on the support line and the projection of the third support portion 121 along the gravity direction G on the support line. In other words, when the child safety seat 1 is installed on the transportation carrier seat 2 facing backward, the projection of the center of gravity CG of the child safety seat 1 along the gravity direction G on the transportation carrier seat 2 is located between the contact point between the adjustment foot 12 and the transportation carrier seat 2 and the contact point between one end of the seat body 2 and the transportation carrier seat 2. This design can ensure that the child safety seat installed facing backward can be stably supported by the second support portion 115 and the third support portion 121.

[0080] The child safety seat of the present invention is not limited to the above-mentioned embodiments. For example, see Fig.11 and Fig.12 , Fig.11 and Fig.12 Schematic diagram of a child safety seat 1' in different positions according to a second embodiment of the present invention. Fig.11 and Fig.12As shown, unlike the first embodiment, the first support portion 114' is directly formed at the front end of the seat body 11' and adjacent to the first end 1111' of the seat portion 111' away from the backrest portion 112', the adjustment foot 12' is pivotally arranged at the rear end of the seat body 11', and the second support portion 115' is formed at the seat portion 111' or the backrest portion 112' and adjacent to the connection between the seat portion 111' and the backrest portion 112'. In other words, in this embodiment, the tilting foot is omitted. The first support portion 114' and the third support portion 121' of the adjustment foot 12' abut against the transportation vehicle seat to support the child safety seat 1' arranged forward on the transportation vehicle seat, and the second support portion 115' and the third support portion 121' abut against the transportation vehicle seat to support the child safety seat 1' arranged backward on the transportation vehicle seat. In addition, regardless of whether the child safety seat 1' of this embodiment is arranged forward or backward, the tilt angle of the child safety seat 1' can be adjusted by pivoting the adjustment foot 12'.

[0081] Furthermore, please see Fig.13 and Fig.14 , Fig.13 FIG. 1 is a schematic diagram of a child safety seat 1" according to a third embodiment of the present invention. Fig.13 As shown, unlike the second embodiment, the adjustment foot 12" of this embodiment is pivotally arranged at the front end of the seat body 11", the tilting foot is omitted, and no matter whether the child safety seat 1" of this embodiment is arranged in a forward or backward manner, the tilt angle of the child safety seat 1" can be adjusted by pivoting the adjustment foot 12". Fig.14 FIG. 1 is a schematic diagram of a child safety seat 1″′ according to a fourth embodiment of the present invention. Fig.14 As shown, unlike the second embodiment, the adjustment foot 12"' of this embodiment is slidably arranged at the bottom of the seat body 11"', the tilting foot is omitted, and no matter whether the child safety seat 1"' of this embodiment is arranged in a forward or backward manner, the tilting angle of the child safety seat 1"' can be adjusted by sliding the adjustment foot 12"'.

[0082] Compared to the prior art, in the present invention, the first support portion and the third support portion abut against the transportation vehicle seat to support the child safety seat arranged forward on the transportation vehicle seat, and the second support portion and the third support portion abut against the transportation vehicle seat to support the child safety seat arranged backward on the transportation vehicle seat. In other words, when the child safety seat is arranged forward on the transportation vehicle seat, the child safety seat can be adjusted to a proper angle by adjusting at least one of the first support portion and the third support portion; when the child safety seat is arranged backward on the transportation vehicle seat, the child safety seat can be adjusted to a proper angle by adjusting at least one of the second support portion and the third support portion, so the present invention has a larger adjustment range. In addition, the child safety seat of the present invention has better structural strength due to the structural reinforcement and can resist larger impacts.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
