Description

Technical Field

[0001] The present application relates to a carrier, a top tether system, a carrier with a connection structure, and a child safety seat. Background Art

[0002] Baskets can be used in vehicles and airplanes to provide safety for infants and young children when traveling. When the basket is used in a vehicle, the basket is detachably connected to a base mounted on a vehicle seat. The base can be fixed to the vehicle seat via an ISOFIX system or a LATCH system, and the base can also be fixed to the vehicle seat using the three-point vehicle seat belt of the vehicle seat. Because baskets are used in vehicles much more frequently than in airplanes, in order to prevent users from mistakenly wrapping the vehicle seat belt around the basket and causing the base to fail to be fixed, existing baskets do not have a structure that can be used to position the vehicle seat belt. When the basket needs to be used on an airplane seat, it is difficult to connect and position the basket with the seat belt of the airplane seat.

[0003] Some existing child safety seats (including the seat body and the base) need to be fixed to the ISOFIX fixing points on the vehicle and also need to be fixed by a top tether. The top tether is generally fixedly connected to the seat body as a whole. However, a child safety seat with a top tether fixedly connected to the seat body will increase the weight of the seat body, making it inconvenient to remove the seat body from the base and use it separately. For example, when the seat body is used as a carry basket alone, it is more laborious for the user to lift the carry basket.

[0004] In order to connect the child safety seat and related accessories, a connection structure needs to be provided on the child safety seat to connect the accessories, for example, a connection structure is provided to connect with the top strap so that the child safety seat can be more firmly fixed on the vehicle seat through the top strap. Therefore, it is necessary to design a connection structure. Utility Model Content

The handle 1008 is, for example, pivotally connected to the main body 1001 , and the user can conveniently move the basket 1100 through the handle 1008 .

[0300] It should be noted that the directional terms such as "front", "back", "left", and "right" of the basket 1100 in the embodiment of the present application are based on the "front", "back", "left", and "right" directions of the child riding in the basket 1100, and the arrows F1 and B1 are used to schematically indicate the "front" and "back" directions of the basket 1100, and the arrows L1 and R1 are used to schematically indicate the "left" and "right" directions of the basket 1100. These directional terms are only used to make the description of the embodiment of the present application clearer, and are not used to improperly limit the scope of protection of the present application.

[0301] See also Figure 1 and Figure 3 The base 1200 can be placed on a vehicle seat (not shown in the figure) and provide a stable support for the basket 1100. The base 1200 may include a seat body 1091, a top rod 1092 and a connector 1093 mounted on the seat body 1091. The seat body 1091 is used to be mounted on a vehicle seat (not shown in the figure), and the body 1001 of the basket 1100 is detachably mounted on the seat body 1091. The seat body 1091 may be provided with a locking mechanism 1911, and the body 1001 of the basket 1100 may be locked on the seat body 1091 by the locking mechanism 1911. When the locking mechanism 1911 is released, the body 1001 of the basket 1100 may be removed from the seat body 1091.

[0302] The top rod 1092 extends upward from the rear end of the seat body 1091, and the top rod 1092 is used to abut against the backrest of the vehicle seat. The connector 1093 is installed at the rear end of the seat body 1091, and the connector 1093 can be plugged into the universal plug interface on the vehicle seat. The connector 1093 can be an ISOFIX plug-in or a LATCH plug-in. In some embodiments, holes 1910 can be provided on the left and right sides of the rear end of the seat body 1091, and the male buckle of the three-point vehicle safety belt matching the vehicle seat can pass through the hole 1910 on one side and then pass out from the hole 1910 on the other side, and then connect with the plug interface on the vehicle seat. In some other embodiments, a top tether (not shown in the figure) can be installed on the seat body 1091 or the basket 1100, and the top tether can pass over the top of the vehicle seat and connect with the anchor point behind the vehicle seat.

[0303] It should be noted that the directional terms such as "front", "rear", "left", and "right" of the base 1200 in the embodiment of the present application refer to the "front", "rear", "left", and "right" directions of the vehicle when the base 1200 is installed on the vehicle seat. In the figure, arrows F2 and B2 are used to schematically indicate the "front" and "rear" directions of the base 1200, and arrows L2 and R2 are used to schematically indicate the "left" and "right" directions of the base 1200. These directional terms are only used to make the description of the embodiment of the present application clearer, and are not used to improperly limit the scope of protection of the present application.

[0304] See also Figure 1 The basket 1100 is installed on the base 1200 in a rearward manner, for example, and the sight of the child sitting in the basket 1100 is toward the rear of the vehicle. It can be understood that the front, rear, left, and right directions of the basket 1100 installed on the base 1200 in a rearward manner are opposite to the front, rear, left, and right directions of the base 1200.

[0305] Continue to see Figure 1The side portion 1001 a of the basket 1100 is provided with a coupling member 1002 and a covering member 1311 . More specifically, the coupling member 1002 and the covering member 1311 are located on the outer sides of the left and right sides of the basket 1100 . Figure 1 In FIG. 1 , the portion of the joint member 1002 covered by the cover member 1311 is shown by a dotted line. Figure 4 In the top view of the carrier 1100 shown, the joint 1002 defines a safety belt for connecting with the outside world (see Figure 6 , for example, a seat belt of an airplane seat, hereinafter referred to as the seat belt 1300), the slot structure 1020 having a joint 1201, the joint 1201 for the seat belt to enter or leave the slot structure 1020. The cover 1311 has a first working mode and a second working mode. In the first working mode, the cover 1311 covers at least a portion of the joint 1002, more specifically, covers at least a portion of the joint 1201, so that the joint 1201 is completely or partially covered by the cover 1311, thereby restricting an external seat belt (a seat belt of a vehicle seat, hereinafter referred to as the vehicle seat belt) from entering the slot structure 1020, effectively avoiding the vehicle seat belt from incorrectly engaging with the slot structure 1020 (such as Figure 5 In the second working mode, the cover 1311 releases the cover of the joint 1201 to allow the safety belt to enter the groove structure 1020. The safety belt 1300 passing through the groove structure 1020 can easily fix the carrier 1100 on the aircraft seat (e.g. Figure 6 ).

[0306] The basket 1100 provided in the embodiment of the present application can be switched to the first use mode or the second use mode by switching the cover 1311 to the first working mode or the second working mode. The first working mode of the cover 1311 corresponds to the first use mode of the basket 1100, and the second working mode of the cover 1311 corresponds to the second use mode of the basket 1100. When the basket 1100 is in the first use mode, the basket 1100 is suitable for use in a vehicle and can be installed on a vehicle seat through the base 1200. At this time, the cover 1311 in the first working mode can prevent the vehicle safety belt from entering the groove structure 1020 through the joint 1201, which can effectively prevent the user from mistakenly installing the vehicle safety belt into the groove structure 1020 and causing the base 1200 to fail to fix. When the basket 1100 is in the second use mode, the basket 1100 is suitable for use in an airplane, and the basket 1100 is, for example, directly placed on an airplane seat (not shown in the figure). At this time, the cover 1311 in the second working mode releases the cover on the joint 1201 and allows the safety belt to enter the groove structure 1020. The safety belt passes through the groove structure 1020 and reliably installs the basket 1100 on the aircraft seat.

[0307] See also Figure 2 , Figure 4 and Figure 5 , shows an exemplary embodiment of the joint member 1002, which may include a connecting portion 1021 and an extending portion 1022. The connecting portion 1021 extends outward from the side portion 1011 of the body 1001. More specifically, the connecting portion 1021 may extend laterally from the outer side surface of the side wing 1015 (e.g. Figure 4 The extension portion 1022 extends outward from the outer end 1211 of the connecting portion 1021 in the front-to-back direction of the basket 1100 (eg, Figure 4 The extending direction SS of the extending portion 1022 is not parallel to nor coincident with the extending direction TT of the connecting portion 1021, that is, an angle (e.g., 90 degrees) is formed between the extending direction SS and the extending direction TT. Figure 5 , the extension direction SS of the extension portion 1022 is not limited to the front-to-back direction parallel to the horizontal plane. In some embodiments, the extension direction SS of the extension portion 1022 may be the front-to-back direction inclined relative to the horizontal plane. In some embodiments, the joint 1002 may be integrally formed with the plastic shell of the body 1001. In some embodiments, the joint 1002 may be mounted to the body 1001, for example, by fasteners (e.g., screws).

[0308] See also Figure 4 The connecting portion 1021, the extending portion 1022 and the side portion 1011 of the body 1001 together define a groove structure 1020. An end of the extending portion 1022 away from the connecting portion 1021 and the side portion 1011 of the body 1001 form a joint 1201 of the groove structure 1020. As mentioned above, the joint 1201 allows the safety belt 1300 to enter or leave the groove structure 1020, so as to allow the carrier 1100 to be fixed to or removed from the aircraft seat.

[0309] Of course, the embodiment of the joint member 1002 is not limited to the above examples, as long as it can form a groove structure 1020 for joining with the safety belt and having a joint 1201. For example, in some alternative embodiments, the extension direction SS of the extension portion 1022 can be perpendicular to the horizontal plane. Figure 4 and Figure 5The extension direction TT of the middle connecting portion 1021 and the extension direction SS of the extension portion 1022 are substantially perpendicular to form a 90 degree angle, but in some alternative embodiments, the extension direction TT and the extension direction SS may form an obtuse angle or an acute angle, for example. In addition, in some alternative embodiments, the joint 1002 may include a base portion (not shown in the figure) connected to the connecting portion 1021 and opposite to the extension portion 1022, and the base portion is installed on the side portion 1011 of the body 1001. The base portion, the connecting portion 1021 and the extension portion 1022 jointly define a groove structure 1020, and a joint 1201 of the groove structure 1020 is formed between the end of the extension portion 1022 away from the connecting portion 1021 and the base portion. In addition, in some alternative embodiments, the joint 1002 may be a hollow closed structure, for example, a closed annular structure (not shown in the figure), the hollow channel of the closed annular structure forms the groove structure 1020, and the port of the hollow channel forms the joint 1201.

[0310] See also Figure 1 , Figure 5 and Figure 6 , an exemplary embodiment of the cover 1311 is shown. Figure 5 , the portion of the joint 1002 covered by the cover 1311 is shown by a dotted line. In this embodiment, the cover 1311 includes, for example, a seat cloth 1003, and the seat cloth 1003 may include a skirt 1031 folded from the upper edge of the side wing 1015 of the body 1001 to the outer side of the body 1001, and the skirt 1031 is used to cover the joint 1002 and the joint 1201. The cover 1311 (more specifically, the skirt 1031) is provided with a first opening 1301 at a position corresponding to the joint 1002. When the cover 1311 is in the first working mode, the skirt 1031 of the seat cloth 1003 covers the joint 1201 to limit the vehicle safety belt from entering the groove structure 1020. It can be understood that when the cover 1311 is in the first working mode, the skirt 1031 is supported by the extension 1022 of the joint 1002 and away from the side 1011 of the body 1001. See also Figure 6 When the cover 1311 needs to be switched to the second working mode, the extension 1022 of the joint 1002 is adapted to pass through the first opening 1301 so that the joint 1201 is exposed outside the cover (more specifically, the skirt 1031), and the safety belt 1300 can directly enter the groove structure 1020 from the joint 1201 and engage with the joint 1002 to fix the carrier 1100 on the aircraft seat. It can be understood that when the cover 1311 is in the second working mode, the skirt 1031 is closer to the outer side of the side 1011 of the body 1001 relative to the extension 1022.

[0311] It can be understood that when the cover 1311 is in the first working mode, the first opening 1301 deviates from the joint 1201, and the first opening 1301 is, for example, closer to the connection portion 1021 relative to the joint 1201, so that the vehicle safety belt cannot directly enter the joint 1201 through the first opening 1301. In some embodiments, the first opening 1301 can be, for example, set at a position corresponding to the connection portion 1021. When the cover 1311 switches to the second working mode, the joint 1002 passes through the first opening 1301. When the cover 1311 is in the second working mode, the first opening 1301 is, for example, sleeved on the connection portion 1021. In some embodiments, the skirt 1031 can be, for example, made of an elastic fabric with a large elastic deformation, so that the first opening 1301 can be easily close to the joint 1201, so that the extension portion 1022 of the joint 1002 passes through the first opening 1301.

[0312] See also Figure 5 In some embodiments, the first opening 1301 is, for example, a substantially rectangular hole. In the extension direction of the coupling member 1002, more specifically, in the extension direction SS of the extension portion 1022 of the coupling member 1002, the size S1 of the first opening 1301 is, for example, smaller than the size S2 of the coupling member 1002 along this direction. In the height direction of the coupling member 1002 perpendicular to the extension direction SS, the size H1 of the first opening 1301 is, for example, larger than the size H2 of the coupling member 1002 along this direction. This makes it easier for the coupling member 1002 to pass through the first opening 1301 along the extension direction SS. Of course, the implementation of the first opening 1301 is not limited to Figure 5 The embodiment shown only requires that the coupling member 1002 be allowed to extend as needed.

[0313] In addition, in some embodiments not shown, the first opening 1301 is, for example, a slit, which may extend along the extension direction SS of the joint member 1002, and the size of the slit is, for example, close to the size S2 of the joint member 1002 along this direction, and the size of the slit in the height direction perpendicular to the extension direction SS is, for example, much smaller than the size H2 of the joint member 1002 along this direction. In some embodiments, the slit may, for example, extend along the height direction perpendicular to the extension direction SS, and the slit only needs to allow the joint member 1002 to pass through it so that the joint opening 1201 is exposed. In some embodiments, the covering member 1311 (more specifically, the skirt 1031) may be made of an elastic material so that the first opening 1301 may be elastically enlarged. To prevent the engaging member 1002 from accidentally passing through the slit, the seat cloth 1003 may also be provided with a sealing member for closing the slit. The sealing member may be, for example, a Velcro, a zipper, a snap, a button, or the like. When the covering member 1311 is in the first working mode, the sealing member closes the slit so that the engaging member 1002 cannot pass through the slit and is covered by the skirt 1031, and the vehicle safety belt cannot enter the groove structure 1020. When the covering member 1311 is in the second working mode, the sealing member opens the slit, the engaging member 1002 can pass through the slit so that the engaging opening 1201 is exposed outside the skirt 1031, and the safety belt can enter the groove structure 1020 from the engaging opening 1201 and engage with the engaging member 1002, so as to fix the carrier 1100 on the aircraft seat.

[0314] In the above embodiment, the covering member 1311 includes the seat cloth 1003 as an example for explanation. In some alternative embodiments, the covering member 1311 may not include the seat cloth 1003. For example, the covering member 1311 may be a fabric connected to the seat cloth 1003, and the fabric is, for example, arranged on the outside of the seat cloth 1003 and may be provided with the above-mentioned first opening 1301. The covering member 1311 may also be detachably connected to the body 1001 and / or the seat cloth 1003 through any suitable positioning structure. The covering member 1311 made of the fabric may cover the joint 1201 to prevent the vehicle safety belt from entering the groove structure 1020, and the joint 1002 may pass through the first opening 1301 to expose the joint 1201 outside the covering member 1311 to allow the safety belt 1300 to enter the groove structure 1020.

[0315] Figure 7 and Figure 8 Another exemplary embodiment of the cover 1311 is shown. Figure 5 and Figure 6 Specifically, the seat fabric 1003 includes a skirt 1031, at least a portion of the skirt 1031 forms the cover 1311, and the cover 1311 does not have the first opening 1301. Figure 7When the covering member 1311 is in the first working mode, the skirt 1031 at least partially covers the joint 1002 and the joint 1201 , and the vehicle safety belt cannot enter the groove structure 1020 . Figure 7 , the portion of the joint 1002 covered by the cover 1311 is shown by a dotted line. A first positioning structure 1004 may be provided between the seat cloth 1003 and the body 1001. More specifically, the first positioning structure 1004 may be provided between the skirt 1031 and the side 1011 of the body 1001. When the cover 1311 is in the first working mode, the seat cloth 1003 is detachably connected to the body 1001 via the first positioning structure 1004. Figure 8 When the cover 1311 needs to be switched to the second working mode, the first positioning structure 1004 releases the positioning of the seat cloth 1003, allowing the skirt 1031 to move upward to expose the joint 1201, and the safety belt 1300 can enter the groove structure 1020 through the joint 1201 and engage with the joint 1002 to fix the basket 1100 on the aircraft seat.

[0316] See also Figure 8 In some embodiments, the first positioning structure 1004 may include a first positioning member 1041 installed on the skirt 1031 and a second positioning member 1042 installed on the side 1011 of the body 1001 (more specifically, the outer side of the side 1011). The first positioning member 1041 and the second positioning member 1042 may be, for example, snaps or other suitable components that match each other.

[0317] Fig. 9 Another exemplary embodiment of the cover 1311 is shown. Figures 5 to 8 A variation of cover 1311 is shown. Fig. 9 , the portion of the joint 1002 covered by the cover 1311 is shown by a dotted line. Specifically, the seat cloth 1003 includes, for example, a skirt 1031, at least a portion of the skirt 1031 serves as the cover 1311, and the cover 1311 has a first opening 1301. A first positioning structure 1004 may be provided between the seat cloth 1003 and the body 1001, more specifically, the first positioning structure 1004 may be provided between the skirt 1031 and the side portion 1011 of the body 1001. When the cover 1311 is in the first working mode, the cover 1311 is as shown in FIG. Figure 5The cover joint 1201 is shown, and the skirt 1031 is detachably connected to the side of the body 1001 through the first positioning structure 1004. When the cover 31 needs to be switched to the second working mode, the first positioning structure 1004 releases the positioning of the skirt 1031, so that the skirt 1031 can be easily moved forward and backward to allow the extension 1022 of the joint 1002 to easily pass through the first opening 1301 so that the joint 1201 is exposed outside the skirt 1031. After the joint 1201 is exposed outside the skirt 1031, the skirt 1031 can be connected to the side 1011 of the body 1001 again through the first positioning structure 1004, thereby fixing the position of the skirt 1031.

[0318] Fig.10 Another exemplary embodiment of the covering member is shown. Specifically, the seat cloth 1003, for example, includes a skirt 1031, and the skirt 1031 is provided with a second opening 1302, and the engaging member 1002 passes through the second opening 1302. The size of the second opening 1302 is, for example, larger than the size of the engaging member 1002, and the skirt 1031 can be attached to the outer side of the side portion 1011 of the body 1001. The covering member includes a movable cover 1312 connected to the seat cloth 1003. When the covering member is in the first working mode, the movable cover 1312, for example, blocks the second opening 1302 or completely covers the engaging member 1002, and the movable cover 1312 can be connected to the seat cloth 1003 through the second positioning structure 1005, so that the vehicle safety belt cannot enter the groove structure 1020. The second positioning structure 1005 can, for example, be a Velcro, a zipper, a snap, a button, or other components. When the cover needs to be switched to the second working mode, the second positioning structure 1005 releases the positioning of the movable cover 1312 to allow the movable cover 1312 to move to expose the coupling member 1002, and the safety belt can enter the groove structure 1020 through the coupling opening 1201 and engage with the coupling member 1002.

[0319] See also Fig.10 In some embodiments, a portion of the edge of the movable cover 1312 is connected to the skirt 1031 of the seat cloth 1003, for example, by sewing. In some embodiments not shown, the movable cover 1312 is detachably connected to the seat cloth 1003, for example, and when the cover needs to be switched to the second working mode, the movable cover 1312 can be removed from the seat cloth 1003. In some embodiments, the movable cover 1312 can be a part of the seat cloth 1003, or the movable cover 1312 can be made of plastic or metal.

[0320] Fig.11 and Fig.12 Yet another exemplary embodiment of a cover is shown. Fig.11, the portion of the joint 1002 covered by the cover is shown by a dotted line. Specifically, the side 1011 of the body 1001 is provided with a recess 1101, and the recess 1101 is, for example, located on the outer side of the side 1011. The joint 1002 is located in the recess 1101, and the joint 1002 itself or together with the body 1001 defines a groove structure 1020 having a joint 1201. The cover includes, for example, a cover 1313, and when the cover is in the first working mode, the cover 1313 is covered on the recess 1101 and covers the joint 1002, so that the vehicle safety belt cannot enter the groove structure 1020. When the cover needs to be switched to the second working mode, the cover 1313 opens the recess 1101 to expose the joint 1002, and the safety belt can enter the groove structure 1020 through the joint 1201 and engage with the joint 1002, so as to fix the carrier 1100 on the aircraft seat. In some embodiments, the cover body can be pivotally connected to the body 1001. In some embodiments, the cover body 1313 can be a part of the seat cloth 1003, or the cover body 1313 can be made of plastic or metal.

[0321] Fig.13 and Fig.14 1310a is a cover member 1311. The cover member 1311 is a fabric belt, for example, and includes a first surface 1311c and a second surface 1311d opposite to each other. The edges of the first surface 1311c and the second surface 1311d are sewn together, for example, to form a receiving space 1310a therebetween. Fig.13 and Fig.14 The outline of the accommodation space 1310a is shown by a dotted line in FIG. Of course, in some other embodiments, the material of the covering member 1311 is not limited to fabric, and its shape is not limited to a belt.

[0322] The first end 1311a of the covering member 1311 is a fixed end, which can be connected to the skirt 1031 of the seat cloth 1003 or the body 1001 in any suitable manner. In this embodiment, the first end 1311a of the covering member 1311 is, for example, sewn together with the skirt 1031. In some other embodiments, the first end 1311a of the covering member 1311 can be, for example, connected to the side 1011 or the bottom of the body 1001.

[0323] The second end 1311b of the covering member 1311 is a free end. Fig.14When the cover 1311 is in the second working mode, the joint 1002 is located above the first end 1311a of the cover 1311, and the second end 1311b of the cover 1311 naturally droops and is located below the first end 1311a. At this time, the cover 1311 is separated from the second joint 1002, the first surface 1311c of the cover 1311 is visible facing away from the body 1001, and the second surface 1311d is invisible facing the body 1001. The safety belt can be easily engaged with the joint 1002 through the joint 1201 to fix the carrier 1100 on the aircraft seat.

[0324] Continue to see Fig.14 The first surface 1311c is provided with a third opening 1311e, the third opening 1311e is communicated with the accommodation space 1310a, and the third opening 1311e is close to the second end 1311b of the cover 1311. When the cover 1311 needs to be switched from the second working mode to the first working mode, the cover 1311 is turned upward relative to the first end 1311a thereof, so that the first surface 1311c is close to the joint 1002. Fig.13 At this time, the first surface 1311c faces the body 1001 and is not visible, and the second surface 1311d faces away from the body 1001 and is visible. When the cover 1311 is flipped upward into place, the extension 1022 of the joint 1002 can enter the accommodation space 1310a through the third opening 1311e. At this time, the cover 1311 can block at least a portion of the joint 1201, thereby limiting the vehicle safety belt from engaging with the joint 1002.

[0325] In some embodiments, the size of the third opening 1311e can be smaller than the size of the outer contour of the extension portion 1022 of the joint member 1002. In this way, after the extension portion 1022 enters the accommodation space 1310a, the third opening 1311e is engaged with the extension portion 1022, which can prevent the extension portion 1022 from accidentally sliding out of the third opening 1311e. In some embodiments, the third opening 1311e can be stretched open during the process of the extension portion 1022 entering the accommodation space 1310a, and returns to its original shape after the extension portion 1022 enters the accommodation space 1310a.

[0326] Fig.15 Another exemplary embodiment of a cover is shown. Fig.13 and Fig.14 A variation of the cover shown is shown, the main difference between the two is the fixing method of the first end 1311a of the cover 1311. In this embodiment, the side portion 1011 of the body 1001 is provided with a narrow and long limiting hole 1102, and the first end 1311a of the cover 1311 is positioned after passing through the limiting hole 1102.

[0327] See also Fig.16 In some embodiments, the first end 1311a of the cover 1311 is provided with a stopper 1035 engaged with the stopper hole 1102, and the stopper 1035 may be, for example, but not limited to, a Japanese buckle. In some alternative embodiments, the first end 1311a of the cover 1311 may be formed by sewing the cover 1311 itself to form the stopper 1035 engaged with the stopper hole 1102.

[0328] This application Figures 17 to 37 The embodiment improves the problem that the top strap system is fixedly connected to the seat body 2110, which causes the top strap system to increase the weight of the seat body 2110 and makes it inconvenient to remove the seat body 2110 from the base 2120 and use it separately.

[0342] In other embodiments, the adjusting member 2170 may also be connected to the first portion 2131 (e.g., connected to the extension portion 2131d), and the total length of the top strap may be adjusted by adjusting the length of the extension portion 2131d (to match different vehicle models). At this time, the second portion 2132 is connected to the first connecting member 2141 and the second connecting member 2142, and the first connecting member 2141 and the second connecting member 2142 are both restricted from passing through the through portion 2121b to restrict the second portion 2132 from being separated from the base 2120 (the second portion 2132 is non-detachably connected to the top rod structure).

[0343] In other embodiments, the top rod structure may not be provided with the connecting portion 2121c, and the through portion 2121b may be formed by other means, for example, the wall surface of the supporting portion 2121a of the top rod structure is penetrated to form the through portion 2121b.

[0344] like Fig. 20 As shown, the top tether system further includes a fixing member 2150 connected to the back side 2111 of the backrest portion 2113 of the seat body 2110, and the surrounding portion 2131a of the first portion 2131 has a first fixing portion 2131b, and the first fixing portion 2131b is matched and connected with the fixing member 2150. In other words, the first fixing portion 2131b of the surrounding portion 2131a of the first portion 2131 is matched and connected with the fixing member 2150 of the back side 2111 of the backrest portion 2113 of the seat body 2110, so as to fix the first portion 2131 to the back side 2111 of the backrest portion 2113 of the seat body 2110.

[0345] like Fig. 22 As shown, the first fixing portion 2131b of the surrounding portion 2131a of the first part 2131 is sleeve-shaped and sleeved on the fixing member 2150 of the back side 2111 of the backrest portion 2113 of the seat body 2110. Preferably, the first fixing portion 2131b of the surrounding portion 2131a of the first part 2131 is elastic so that the first fixing portion 2131b can be elastically deformed to accommodate the fixing member 2150, that is, the first fixing portion 2131b is an elastic sleeve so as to be elastically fastened to the fixing member 2150. The first fixing portion 2131b of the surrounding portion 2131a of the first part 2131 can be sewn integrally with the first part 2131 itself (webbing); or a part of it can be a webbing and a part of it can be an additionally sewn belt (elastic band); or the entire first fixing portion 2131b can be a component that is additionally sewn to the surrounding portion 2131a of the first part 2131. Preferably, as Fig. 20 As shown, the first part 2131 includes an elastic band and a webbing, the two ends of the elastic band are sewn on the webbing, the upper and lower ends of the elastic band are not closed and form a ring together with a part of the webbing to form a first fixing part 2131b of the surrounding part 2131a.

[0346] like Fig. 22 As shown, the fixing member 2150 has a mounting portion 2151 for mounting on the back surface 2111 of the backrest portion 2113 of the seat body 2110 and a second fixing portion 2152 connected to the mounting portion 2151, a gap 2153 is formed between the mounting portion 2151 and the second fixing portion 2152, and the first fixing portion 2131b is sleeved on the second fixing portion 2152 and partially located in the gap 2153. Specifically, a portion of the webbing of the surrounding portion 2131a is located in the gap 2153, and the elastic band sewn on the webbing is located outside the second fixing portion 2152, and the elastic band has a force to tightly sleeve the first fixing portion 2131b on the second fixing portion 2152 due to being stretched. One end 2152b of the second fixing portion 2152 of the fixing member 2150 is connected to the mounting portion 2151 of the fixing member 2150, and the other end 2152d of the second fixing portion 2152 is suspended to form an opening in the fixing member 2150. A blocking portion 2154 is provided at a position corresponding to the opening of the second fixing portion 2152 of the fixing member 2150, and the blocking portion 2154 restricts the first fixing portion 2131b from being separated from the second fixing portion 2152, so as to restrict the first portion 2131 from being separated from the seat body 2110. That is, when the first fixing portion 2131b and the fixing member 2150 are connected, the sleeve-shaped (ring-shaped) first fixing portion 2131b of the surrounding portion 2131a of the first portion 2131 passes over the blocking portion 2154 from the other end 2152d of the second fixing portion 2152 of the fixing member 2150, and is sleeved on the second fixing portion 2152 of the fixing member 2150 through the gap between the blocking portion 2154 and the mounting portion 2151. The shape of the blocking portion 2154 (for example, Fig. 22 The barbed barb shape shown in the figure is configured so that the sleeve-shaped (ring-shaped) first fixing portion 2131b of the surrounding portion 2131a of the first portion 2131 can be easily put on the second fixing portion 2152 of the fixing member 2150 through the gap between the blocking portion 2154 and the mounting portion 2151, and then be restricted by the blocking portion 2154 to prevent it from being separated from the second fixing portion 2152. Of course, the fixing method of the first portion 2131 and the seat body 2110 is not limited to this. Even if the first portion 2131 is also a flexible belt-shaped structure, the first portion 2131 can be directly fixed to the back side 2111 of the seat body 2110 by fasteners such as rivets and screws.

[0347] like Fig. 20As shown, the child safety seat 2100 further includes a storage bag 2180 for storing the first part 2131, and the storage bag 2180 is connected to the first part 2131 or the seat body 2110. The child safety seat 2100 according to the present application further includes a seat cloth provided on the seat body 2110, and the storage bag 2180 can also be connected to the seat cloth. Therefore, when the first part 2131 of the top tether system needs to be removed from the child safety seat 2100 (the user intentionally operates to remove the first part 2131 from the seat body 2110, rather than accidentally losing it), the first part 2131 remaining on the seat body 2110 can be placed in the storage bag 2180 (the surrounding part 2131a of the first part 2131 is separated from the seat body 2110 and placed in the storage bag 2180), so that the appearance of the seat body 2110 is neat and tidy, and the seat body 2110 is convenient to use alone. That is to say, after the seat body 2110 is taken out separately, the first part 2131 of the top tether system which is a flexible belt structure can be stored in the storage bag 2180 .

[0348] Fig.23 The third embodiment of the child safety seat according to the present application is a three-dimensional schematic diagram, which is different from the first embodiment in that the surrounding portion 2131a of the first part 2131 has two free ends 2131c, the second part 2132 includes a first end 2132a and two second ends 2132b, the first end 2132a is used to connect to the vehicle, and the two free ends 2131c are detachably connected to the two second ends 2132b. In this embodiment, two third connecting members 2143 are respectively connected to the two free ends 2131c, and the two third connecting members 2143 are respectively detachably connected to the two second connecting members 2142 connected to the two second ends 2132b. Preferably, the two free ends 2131c of the surrounding portion 2131a of the first portion 2131 are located at a substantially upper and lower middle and left-right symmetrical position of the back side 2111 of the backrest portion 2113 of the seat body 2110 (the surrounding portion 2131a of the first portion 2131 is arranged around the back side 2111 of the backrest portion 2113 of the seat body 2110 and extends to the side wings 2114 on both sides), and the connection points of the two free ends 2131c of the surrounding portion 2131a of the first portion 2131 and the two second ends 2132b of the second portion 2132 are located at a substantially upper and lower middle and left-right symmetrical position of the seat body 2110, so that when the child safety seat according to the present application is used in a vehicle, the top tether system can fix the seat body 2110 to the vehicle with balanced force. The second portion 2132 having two second ends 2132b and a first end 2132a is a Y-shaped flexible belt structure as a whole. That is, the three branches of the second portion 2132 form two second ends 2132b and a first end 2132a, and at the middle intersection (eg Fig.23The stitches shown (2133) meet to form a Y-shaped structure.

[0349] Fig.24 Based on Fig.23 The perspective schematic diagram of the child safety seat 2100 from another perspective more clearly shows the specific position of the detachable connection between the second end 2132b of the second part 2132 and the surrounding portion 2131a of the first part 2131.

According to the child safety seat 2100 of the present application, after the first part 2131 and the second part 2132 are disassembled from each other, the seat body 2110 (carrying basket) can be taken out separately (such as Fig.25 When the top tether system is connected, the child safety seat 2100 is fixed to the vehicle. After the seat body 2110 of the child safety seat according to the present application is lifted away, the first part 2131 is restricted from being separated from the seat body 2110 and remains on the seat body 2110 (as shown in FIG. Fig.25 As shown), the second portion 2132 is restricted from detaching from the base 2120 and can remain on the base 2120 (as shown Fig.26 As shown), the top lacing system can be avoided from being lost, and since the second portion 2132 remains on the base 2120, the weight of the seat body 2110 (basket) can be reduced, making it easier for the seat body 2110 to be used alone.

[0351] It should be noted that the second embodiment is also provided with an adjustment member 2170, the second portion 2132 may also include an adjustment section 2132d and a connection section 2132c, and the top rod structure also includes a top rod 2121 and a connection portion 2121c. These corresponding structures and the specific manner in which the second portion 2132 is limited to the top rod structure are similar to those of the first embodiment described above, and will not be repeated here. In addition, the second embodiment also has a fixing member 2150 disposed on the back side 2111 of the seat body 2110, and the connection manner between the surrounding portion 2131a and the fixing member 2150 is similar to that of the first embodiment described above, and will not be repeated here. Similarly, the child safety seat 2100 of the second embodiment may be provided with a storage bag 2180, and after the seat body 2110 is taken out separately, the first portion 2131 of the top tether system in a flexible belt-like structure can be stored in the storage bag 2180.

[0352] Fig. 27 It is a three-dimensional schematic diagram of a third embodiment of a child safety seat 2100 according to the present application. Fig.28 Based on Fig. 27 The three-dimensional schematic diagram of the child safety seat 2100 from another perspective more clearly shows the specific position of the detachable connection between the first part 2131 and the second part 2132. Fig.28 As shown, the first portion 2131 is a non-flexible structure (eg, a metal structure) fixed to the seat body 2110 , and the second portion 2132 is a flexible belt-like structure (eg, a webbing).

[0353] like Figure 27-Figure 28 As shown, the second part 2132 has a first end 2132a and a second end 2132b, and the top tether system further includes: a first connector 2141, which is disposed at the first end 2132a and is used to connect to the vehicle; a second connector 2142, which is disposed at the second end 2132b and is detachably connected to the first part 2131. One of the second connector 2142 and the first part 2131 has a hook, and the other of the second connector 2142 and the first part 2131 has a fixing hole 2131e (such as Fig.29 As shown), the hook is snap-fitted with the fixing hole 2131e. In this embodiment, the second connecting member 2142 has a hook, and the first portion 2131 has a fixing hole 2131e. In other embodiments, the positions of the hook and the fixing hole 2131e can be interchanged.

[0354] like Fig.28 As shown, the first part 2131 is fixed to the back side 2111 of the backrest 2113 of the seat body 2110, the first part 2131 includes two fixing holes 2131e, and the second part 2132 has two second ends 2132b for connecting with two second connecting members 2142 respectively, each second connecting member 2142 has a hook, and the two hooks are connected with the two fixing holes 2131e in a one-to-one corresponding manner. There are different implementations for fixing the first part 2131 to the seat body 2110: the first part 2131 is installed and fixed to the seat body 2110, for example, the first part 2131 is a metal sheet and is installed to the seat body 2110 by fasteners such as rivets or screws; or the first part 2131 is fixed to the seat body 2110 by an integral molding method.

[0355] The second portion 2132 having a first end 2132a and two second ends 2132b is a Y-shaped flexible band structure as a whole. That is, the three branches of the second portion 2132 form the first end 2132a and the two second ends 2132b, and at the middle intersection (such as Fig. 27 The stitches shown (2133) meet to form a Y-shaped structure.

[0356] like Figure 29-Figure 30As shown, the first part 2131 is located outside the back side 2111 of the backrest portion 2113 of the seat body 2110. The second part 2132 is used to connect to the top rod structure of the base 2120, and the top rod structure of the base 2120 is used to lean against the vehicle. The first part 2131 installed on the seat body 2110 also includes a mounting hole 2131f, and a fastener passes through the mounting hole 2131f to connect and fix with the mounting column 2131g on the back side of the backrest portion 2113 of the seat body 2110 to install the first part 2131 on the seat body 2110. Preferably, the first part 2131 is a fixed iron sheet, which is fixed to the back of the backrest 2113 of the seat body 2110 by fasteners; of course, it can also be integrally injection molded with the backrest 2113 of the seat body 2110, and then a reinforcing iron sheet or local thickening treatment is arranged in its fixing hole 2131e to ensure that it is strong enough to connect with the second connecting member 2142 to firmly fix the child safety seat 2100 according to the present application to the vehicle. It should be noted that the first part 2131 is fixed to the outer side of the back 2111 of the backrest 2113 of the seat body 2110 by separate installation or integral molding, so that the top tether system can be applied without damaging the rigidity of the seat body 2110 (protection performance for children).

[0357] Preferably, the first part 2131 installed on the seat body 2110 is located at the approximate center of the back 2111 of the backrest 2113 of the seat body 2110, and the connection points of the two second connecting members 2142 and the two fixing holes 2131e of the first part 2131 are located at the approximate middle and left-right symmetrical positions of the back 2111 of the backrest 2113 of the seat body 2110, so that when the child safety seat according to the present application is used in a vehicle, the top tether system can fix the seat body 2110 to the vehicle with balanced force. The intersection of the three branches of the second part 2132 forms the middle intersection point of the Y-shaped structure, and when the top tether system is connected to the vehicle for use, the middle intersection point is also located at the approximate longitudinal symmetric plane of the seat body 2110, so that when the child safety seat according to the present application is used in a vehicle, the top tether system can fix the seat body 2110 to the vehicle with balanced force.

[0358] Fig.29 Based on Fig. 27 The state of the seat body 2110 of the child safety seat 2100 when the seat body 2110 leaves the base 2120, Fig.31 Based on Fig. 27 The state of the seat body 2110 of the child safety seat 2100 after the base 2120 is removed. According to the child safety seat 2100 of the present application, after the first part 2131 and the second part 2132 are disassembled from each other, the seat body 2110 (carrying basket) can be taken out separately (such as Fig.29When the top tether system is connected, it is used to secure the child safety seat 2100 to the vehicle. Fig. 27 After the seat body 2110 of the child safety seat is lifted, the first portion 2131 is restricted from being separated from the seat body 2110 and thus remains on the seat body 2110, and the second portion 2132 is restricted from being separated from the base 2120 and can remain on the base 2120 (such as Fig.31 As shown), the top strap system is avoided from being lost, and the weight of the seat body 2110 (basket) can be reduced. It should be noted that the third embodiment is also provided with an adjustment member 2170, the second portion 2132 may also include an adjustment section 2132d and a connecting section 2132c, and the top rod structure also includes a top rod 2121 and a connecting portion 2121c. These corresponding structures and the specific manner in which the second portion 2132 is restricted to the top rod structure are similar to those of the first embodiment described above, and will not be repeated here.

[0359] In the first to third embodiments, the top tether system includes a first connector 2141 and a second connector 2142 both connected to the second portion 2132, and may further include an adjusting member 2170 connected to the second portion 2132. The first connector 2141 is used to connect to the vehicle, and the second connector 2142 is used to connect to the first portion 2131 of the top tether system. The first connector 2141 and the second connector 2142 are both restricted from passing through the through portion 2121b, or the first connector 2141 and the adjusting member 2170 are both restricted from passing through the through portion 2121b, or the second connector 2142 and the adjusting member 2170 are both restricted from passing through the through portion 2121b, so as to restrict the second portion 2132 from being separated from the base 2120. After the first part 2131 and the second part 2132 of the child safety seat 2100 according to the present application are disassembled from each other, the seat body 2110 (basket) can be taken out separately, and when the top tether system is connected, it is used to fix the child safety seat 2100 to the vehicle. After the seat body 2110 of the child safety seat according to the present application is taken away, since the first part 2131 is restricted from being separated from the seat body 2110, and the second part 2132 with a flexible belt structure can also be left on the base 2120 (the second part 2132 is inserted into the through-hole 2121b and is restricted from being detached from the through-hole), the first part 2131 and the second part 2132 can be prevented from being lost, and the weight of the seat body 2110 (basket) can be reduced. The second part 2132 is fixedly connected to the base 2120, which not only prevents the second part 2132 from being lost, but also allows the base 2120 to be installed on the vehicle seat once and connect the second part 2132 to the vehicle (regardless of whether the seat body 2110 is moved away or moved back and installed on the base 2120 again). This part (the base 2120 and the second part 2132 that have been installed on the vehicle) does not need to be reinstalled, and is easy to use.

[0360] Fig.32 It is a three-dimensional schematic diagram of a fourth embodiment of a child safety seat 2100 according to the present application. Fig.33 Based on Fig.32 The state of the seat body 2110 of the child safety seat 2100 when the seat body 2110 leaves the base 2120. Fig.36 Based on Fig.32 The state of the base 2120 after the seat body 2110 of the child safety seat is removed. In this embodiment, the first part 2131 is fixed to the seat body 2110, and the second part 2132 is a flexible belt-like structure (for example, a webbing). The first part 2131 can be a non-flexible structure (for example, a metal structure), the first part 2131 can also be a flexible structure (for example, a fabric), and the first part 2131 can have a certain elasticity, as long as its strength is sufficient to work together with the second part 2132 to firmly fix the child safety seat 2100 according to the present application to the vehicle.

[0361] like Fig.32 As shown, the second part 2132 has a first end 2132a and two second ends 2132b, and the top tether system also includes a first connecting member 2141 and two fourth connecting members 2144. The first connecting member 2141 is arranged at the first end 2132a and is used to connect to the vehicle, and the two fourth connecting members 2144 are respectively arranged at the two second ends 2132b and are detachably connected to each other.

[0362] Specifically, in order to make the two fourth connecting members 2144 more firmly connected to each other in the tightened state when the second part 2132 is used, in the present embodiment, one of the two fourth connecting members 2144 has a hook, and the other of the two fourth connecting members 2144 has a connecting hole, and the hook and the connecting hole are snap-fitted so that the two second ends 2132b of the second part 2132 can be quickly connected or disassembled. In some embodiments, the two fourth connecting members 2144 can be structures such as Velcro or snaps. It should be noted that in some embodiments, any of the two fourth connecting members 2144 can be selectively arranged, for example, the two second ends 2132b of the second part 2132 are directly tied to each other in a flexible belt-like structure, or one second end 2132b of the second part 2132 is tied or penetrated in a flexible belt-like structure and is snap-connected to the fourth connecting member 2144 (for example, the fourth connecting member 2144 in the form of a Japanese buckle) arranged at the other second end 2132b.

[0363] like Fig.32 , Fig.33As shown, the second portion 2132 has a surrounding portion 2132e, and the surrounding portion 2132e is used to surround the back side 2111 of the seat body 2110, and the first portion 2131 is passed through by the surrounding portion 2132e. Specifically, in this embodiment, the second portion 2132 is a Y-shaped structure, that is, two branches extend from the first end 2132a to form two second ends 2132b. In this embodiment, the surrounding portion 2132e of the second part 2132 surrounding the back surface 2111 is provided at one of the branches. When the top strap system is installed and used, the second end 2132b of one of the branches connected with the hook or the connecting hole of the second part 2132 bypasses one side wing 2114 of the seat body 2110 and surrounds the back surface 2111, so that the surrounding portion 2132e passes through the first part 2131 from the back surface 2111 of the seat body 2110, and then the second end 2132b bypasses the other side wing 2114 of the seat body 2110 and snap-fits with the second end 2132b of the other branch. In this embodiment, if the two side wings 2114 are considered to be connected to the opposite sides of the back surface 2111 in the left-right direction, the connection position of the two fourth connecting members 2144 is located at one side of the first part 2131 in the left-right direction.

[0364] It should be noted that, in other embodiments, the surrounding portion 2132e of the second portion 2132 may be formed by two branches. It is understandable that when the two second ends 2132b are connected to each other on the outside of the back surface 2111, rather than being connected to each other on the outside of the side wing 2114, the surrounding portion 2132e surrounding the back surface 2111 is formed by two branches. For example, in one embodiment, after the surrounding portions 2132e of the two branches pass through the first portion 2131 respectively (the two surrounding portions 2132e pass through the first portion 2131 at the same time), the two fourth connecting members 2144 are detachably connected to the back side of the first portion 2131. In this embodiment, the first portion 2131 can be fixed to the middle position of the back surface 2111 of the seat body 2110, so that the first portion 2131 and the second portion 2132 can be connected to each other with balanced force. For another example, the first portion 2131 is not fixed at the middle position of the back side 2111, but is biased toward one side of the back side 2111, that is, if the two side wings 2114 are considered to be connected to the left and right sides of the back side 2111, the first portion 2131 is biased toward the left side wing 2114 or the right side wing 2114 of the back side 2111. At this time, the two branches can jointly form a surrounding portion 2132e to surround the back side 2111, and the two second ends 2132b of the two branches (or two fourth connecting portions 2144) are connected on one side of the first portion 2131, that is, the connection position of the two second ends 2132b (or two fourth connecting portions 2144) is between the first portion 2131 and the right side wing 2114 or between the first portion 2131 and the left side wing 2114.

[0365] It can be understood that the two fourth connecting members 2144 of this embodiment are used to be detachably connected on one side outside the first part 2131 to facilitate user operation, where "one side outside the first part 2131" can be one of the sides in the left and right directions, or it can be the back side of the first part 2131.

[0366] like Fig.36 As shown, the first part 2131 has a mounting portion 2151a for mounting on the back side 2111 of the seat body 2110 and a second fixing portion 2152a connected to the mounting portion 2151a, a gap 2153a is formed between the mounting portion 2151a and the second fixing portion 2152a, and the surrounding portion 2132e of the second part 2132 passes through the gap 2153a. One end 2152c of the second fixing portion 2152a of the first part 2131 is connected to the mounting portion 2151a of the first part 2131, and the other end 2152e of the second fixing portion 2152a is suspended so that an opening is formed in the first part 2131. A blocking portion 2154a is provided at a position corresponding to the opening of the second fixing portion 2152a of the first part 2131, and the blocking portion 2154a limits the surrounding portion 2132e of the second part 2132 from being separated from the gap 2153a, so as to prevent the second part 2132 and the first part 2131 from being accidentally separated after being connected to each other. That is, when the surrounding portion 2132e passes through the first portion 2131 from the back side 2111 of the seat body 2110, the surrounding portion 2132e passes over the blocking portion 2154a from the other end 2152e of the second fixing portion 2152a of the first portion 2131 and enters the gap 2153a between the blocking portion 2154a and the mounting portion 2151a. The shape of the blocking portion 2154a (e.g., Fig.36The barb-shaped portion 2154a shown in the figure is configured so that the surrounding portion 2132e can easily pass over the blocking portion 2154a and enter the gap 2153a, and then be restricted by the blocking portion 2154a to prevent it from detaching from the second fixing portion 2152a. The second fixing portion 2152a or the blocking portion 2154a has elasticity so that when the seat body 2110 is disassembled from the base 2120, the surrounding portion 2132e can be detached from the gap 2153a by utilizing the elastic deformation of the second fixing portion 2152a or the blocking portion 2154a. Of course, the fixing method of the first portion 2131 to the seat body 2110 is not limited to this. If the first portion 2131 is a flexible structure (for example, fabric), the first portion 2131 can also be directly fixed to the corresponding fabric on the back side 2111 of the seat body 2110 by sewing or the like. That is, there are different implementations for fixing the first part 2131 to the seat body 2110, for example: the first part 2131 is installed and fixed to the seat body 2110, such as the first part 2131 is installed to the seat body 2110 by fasteners such as rivets or screws or by a clamping structure between the first part 2131 and the seat body 2110; or, the first part 2131 is fixed to the seat body 2110 by an integral molding method. It should be noted that the first part 2131 is fixed to the outer side of the back surface 2111 of the backrest 2113 of the seat body 2110 by separate installation or integral molding, so that the top tether system can be applied without damaging the rigidity of the seat body 2110 (protection performance for children).

[0367] Preferably, the first portion 2131 installed on the seat body 2110 is located at the approximate center of the back 2111 of the backrest portion 2113 of the seat body 2110, so that when the child safety seat according to the present application is used in a vehicle, the top tether system can fix the seat body 2110 to the vehicle with balanced force. The second portion 2132 having two second ends 2132b and one first end 2132a is a Y-shaped flexible belt structure as a whole, wherein the branch where one second end 2132b is located is longer than the branch where the other second end 2132b is located due to the surrounding portion 2132e (e.g., Fig.32 , Fig.37 ). That is, the length from one fourth connecting member 2144 to the first end 2132a is greater than the length from another fourth connecting member 2144 to the first end 2132a. The intersection of the three branches of the second portion 2132 forms a middle intersection point of the Y-shaped structure (having the same stitching 2133 as the previous embodiment). When the top tether system is connected to the vehicle for use, the middle intersection point is also located on the substantially longitudinal symmetric plane of the seat body 2110, so that when the child safety seat according to the present application is used in the vehicle, the top tether system can fix the seat body 2110 to the vehicle with balanced force.

[0368] In this embodiment, the two second ends 2132b of the second part 2132 are detachably connected. Specifically, the two fourth connecting members 2144 (hooks and connecting holes) are detachably connected on the side (flank surface) of the seat body 2110. When the caregiver does not need to lift the seat body 2110 and only wants to take the baby away, the caregiver only needs to remove the hooks and the connecting holes. The caregiver can pick up the baby from the side of the seat body 2110 and maintain the connection between the second part 2132 and the first part 2131. When the baby is put into the seat body 2110 again, the caregiver does not need to connect the second part 2132 to the first part 2131. The caregiver only needs to connect the hooks of the second part 2132 to the connecting holes. The webbing (second part 2132) blocks the path for the child to enter and exit the seat body 2110, so it is also convenient to use. It should be noted that the fourth embodiment is also provided with an adjusting member 2170, the second part 2132 may also include an adjusting section 2132d and a connecting section 2132c, and the top rod structure also includes a top rod 2121 and a connecting portion 2121c. These corresponding structures and the specific manner in which the second part 2132 is limited to the top rod structure are similar to those of the first embodiment mentioned above and will not be repeated here.

[0369] In addition, similar to the first to third embodiments, in this embodiment, after the first part 2131 and the second part 2132 of the child safety seat 2100 according to the present application are disassembled from each other, the seat body 2110 (basket) can be taken out separately, and when the top tether system is connected, it is used to fix the child safety seat 2100 to the vehicle. After the seat body 2110 of the child safety seat according to the present application is taken away, since the first part 2131 is restricted from being separated from the seat body 2110, and the second part 2132 in a flexible belt-like structure can also be left on the base 2120 (the second part 2132 is inserted into the through-hole 2121b and is restricted from being detached from the through-hole), the first part 2131 and the second part 2132 can be prevented from being lost, and the weight of the seat body 2110 (basket) can be reduced. The second part 2132 is fixedly connected to the base 2120, which not only prevents the second part 2132 from being lost, but also allows the base 2120 to be installed on the vehicle seat once and connect the second part 2132 to the vehicle (regardless of whether the seat body 2110 is moved away or moved back and installed on the base 2120 again). This part (the base 2120 and the second part 2132 that have been installed on the vehicle) does not need to be reinstalled, and is easy to use.

[0370] It should be noted that, in the above-mentioned embodiments, in order to connect the second part 2132 to the top rod structure, before the second part 2132 is connected to the first connecting member 2141, the second connecting member 2142 (in the fourth embodiment, the fourth connecting member 2144 replaces the second connecting member 2142) and the adjusting member 2170, the second part 2132 first passes through the through-portion 2121b, and then the first connecting member 2141, the second connecting member 2142 (in the fourth embodiment, the fourth connecting member 2144 replaces the second connecting member 2142) and the adjusting member 2170 are connected to the second part 2132, and then the second part 2132 can be restricted from detaching from the base 2120. Alternatively, the first connecting member 2141, the second connecting member 2142 (in the fourth embodiment, the fourth connecting member 2144 replaces the second connecting member 2142) and the adjusting member 2170 are connected to the second part 2132, and before the connecting part 2121c is connected to the top rod 2121, the second part 2132 is passed through the top rod 2121, and then when the connecting part 2121c is connected to the supporting part 2121a, the second part 2132 is simultaneously arranged to be located in the through-portion 2121b between the supporting part 2121a and the connecting part 2121c.

[0371] It should be noted that in the above-mentioned embodiments, the second part 2132 is restricted from being separated from the base 2120 by restricting any two of the adjusting member 2170, the first connecting member 2141 and the second connecting member 2142 (in the fourth embodiment, the fourth connecting member 2144 replaces the second connecting member 2142) from passing through the through-portion 2121b, so that no additional components are required, the cost is low and the installation steps are few. However, in addition to this method, other methods can also be used to restrict the second part 2132 from being separated from the base 2120. For example, the second part 2132 is a webbing structure, and a part of it is sewn to form a ring structure and surround the top rod structure; or the second part 2132 is a webbing structure, and a part of it is stacked into multiple layers and sewn to form a thicker knot, which is restricted from passing through the through-portion 2121b; or two other additional components (such as plastic stoppers) are specially set to connect to the second part 2132, and the two components are located on both sides of the top rod structure to be restricted from passing through the through-portion 2121b.

[0372] It should be noted that the third embodiment has two second connecting members 2142 located on the same side of the through-portion 2121b, and the fourth embodiment has two fourth connecting members 2144 located on the same side of the through-portion 2121b. When the second connecting member 2142 or the fourth connecting member 2144 is needed to help limit the second part 2132 from detaching from the base 2120, the present application does not limit all the second connecting members 2142 or all the fourth connecting members 2144 to be restricted from passing through the through-portion 2121b. It is only necessary that any one of the second connecting members 2142 or the fourth connecting member 2144 be restricted from passing through the through-portion 2121b.

[0373] For example, in the fourth embodiment, there are two fourth connecting members 2144 located on the same side of the through-portion 2121b and detachably connected to each other. One of the fourth connecting members 2144 in the fourth embodiment is flat and has a connecting hole, and the other fourth connecting member 2144 has a hook. In the fourth embodiment, one of the fourth connecting members 2144 (i.e., the fourth connecting member 2144 with the hook) is restricted from passing through the through-portion 2121b. Even if there is a flat fourth connecting member 2144 that can pass through the through-portion 2121b, since the two fourth connecting members 2144 are located on the same side of the through-portion 2121b, the second portion 2132 can be restricted from being separated from the base 2120.

[0374] Reference FIG. 38A to FIG. 39B The child safety seat 3001 and the connection structure 3100 according to the present application are generally described. In the embodiment of the present application, the connection structure 3100 is applied to the child safety seat 3001. However, it should be understood that in other embodiments, the connection structure 3100 can also be applied to other forms of carriers such as a sleeping basket, a pet box, etc.

[0375] The child safety seat 3001 includes a seat body 3200 and two connecting structures 3100. The seat body 3200 is a part for children to sit on, and includes a backrest 3220, a seat 3230 and two side wings 3210. In this application, for the convenience of description, the front-to-back direction of the seat body 3200 is referred to as the longitudinal direction, the up-down direction is referred to as the vertical direction, and the left-right direction is referred to as the transverse direction. However, it should be understood that these directions do not limit the arrangement of the child safety seat 3001 and the connecting structure 3100, and the longitudinal, transverse and vertical directions do not have to be perpendicular to each other.

[0376] The child safety seat 3001 may further include one or more cushion blocks 3600 disposed on the seat body 3200 . The cushion blocks 3600 are placed in the seating space of the child safety seat 3001 . Fig.38AThe diagram shows a cushion block 3600 extending vertically and having a top higher than the seat body 3200. The cushion block 3600 can be supported above the side wings 3210 and the backrest 3220. The cushion block 3600 is made of foam material (such as EPP material) and can also be set in other known forms in the field. The child safety seat 3001 can also include a seat cloth (not shown) covering the cushion block 3600.

[0377] The connection structure 3100 has a cover 3130 that can be opened to expose the interior of the connection structure 3100 (see FIG. Fig.38A and Fig.38B ) or closed to shield the interior of the connection structure 3100 (see Fig.39A and Fig.39B The connection structure 3100 and the cover body 3130 will be described in detail below.

[0378] Fig.40 A side view of the other side of the child safety seat 3001 is shown, in which it can be seen that the other side is also provided with a connecting structure 3100. That is, two connecting structures 3100 can be symmetrically arranged on both sides of the child safety seat 3001. However, two connecting structures 3100 can also be arranged asymmetrically, or only one connecting structure 3100 can be arranged.

[0379] Reference Figures 41 to 42B The overall structure of the child safety seat 3001 is further described.

[0380] The child safety seat 3001 of this embodiment is a child basket, and the child safety seat 3001 also has a handle 3400 pivotally connected to both sides of the seat body 3200. The handle 3400 can rotate relative to the seat body 3200, for example, around a transverse axis. Thus, the user can lift the seat body 3200 by the handle 3400. The child safety seat 3001 is used to be detachably connected to a base (not shown), and the base can be installed in a vehicle (not shown), so that the child safety seat 3001 can be connected to the base and used in the vehicle or separated from the base and used as a basket alone. The child safety seat 3001 also includes two connecting parts 3500 connected to the seat 3230, and each connecting part 3500 can be arranged below the seat 3230. The two connecting parts 3500 are arranged at intervals from each other and are configured to be connected to the base. For example, the connecting part 3500 can be connected to the base through another snap-fit ​​mechanism (not shown), and the present application does not limit the form of the snap-fit ​​mechanism. Of course, in other embodiments, the child safety seat 3001 may be in other forms, not limited to the child carrier form.

[0381] The backrest 3220 is located behind the seat 3230 and extends upward, and the two side wings 3210 are respectively located on both sides of the backrest 3220. The side wings 3210 are used to provide a more comfortable and safe riding environment for children, and some devices of the child safety seat 3001 can be installed on the side wings 3210. Both connecting parts 3500 extend downward to facilitate downward installation to the base (not shown).

[0382] The two connection structures 3100 are respectively arranged at the two side wings 3210. More specifically, in this embodiment, the connection structure 3100 can be arranged near the vertical middle position of the seat body 3200, but is not limited thereto, and the position of the connection structure 3100 can be flexibly adjusted according to the installation requirements of the tether 3300.

[0383] Reference FIG. 42A to FIG. 42B ,in Fig.42B The tether 3300 is schematically shown connected to the child safety seat 3001 .

[0384] More specifically, the handle 3400 has two pivoting portions 3410 connected to both sides of the seat body 3200, each pivoting portion 3410 having a pivot center 3411. The handle 3400 can rotate relative to the seat body 3200 around the pivot center 3411. The connecting structure 3100 is disposed on the side wing 3210 and is close to the rear and upper part of the seat body 3200 relative to the pivot center 3411. For example, in this embodiment, each side wing 3210 has an extension portion 3211 extending outward and downward from its upper edge (see FIG. 38, Fig.42A ), the connection structure 3100 is located below the extension 3211. In addition, the connection structure 3100 can be located above the seat body 3200 relative to the connection part 3500. The seat cloth (not shown) of the child safety seat covers the cushion block 3600 and can extend outward to wrap the side of the cushion block 3600. The seat cloth can also be clamped at the extension 3211 to connect the seat cloth to the seat body 3200. In addition, the connection structure 3100 is located in front of the front surface of the backrest 3220 of the seat body 3200 in the front-to-back direction.

[0385] It should be understood that the bottom of a common child safety seat can be fixed to a vehicle such as a vehicle through a base, so when the vehicle is hit, the upper part of the seat body may tilt, for example, tilt to the rear of the child safety seat (i.e., the front of the vehicle), thus causing safety hazards. According to the overall structure of the child safety seat 3001 of the present application, the position of the connecting structure 3100 is close to the rear and top of the seat body 3200. Therefore, the tether 3300 connected to the child safety seat 3001 through the connecting structure 3100 can apply a large pulling force moment to the seat body 3200, which is advantageous in preventing the seat body 3200 from tilting backward. On the other hand, since there is a certain distance between the connecting structure 3100 and the upper edge of the seat body 3200, the structural strength of the seat body 3200 is basically not affected. Furthermore, when the child safety seat 3001 is installed in a vehicle, the side wing 3210 of the child safety seat 3001 faces the door. Since the connection structure 3100 is disposed at the side wing 3210 , the user can operate the connection structure 3100 at the vehicle door to connect or disconnect the tether 3300 to or from the seat body 3200 , thereby increasing the convenience of operation.

[0386] In the present application, the tether 3300 is connected to the upper portion of the side wing 3210 of the seat body 3200. However, the present application is not limited thereto, and the tether 3300 may also be connected to other appropriate positions of the seat body 3200, such as the bottom or the back.

[0387] More specifically, the tether 3300 includes an extension 3330 and two branches 3320. One end of each branch 3320 is respectively connected to two connection structures 3100 provided on the seat body 3200, and the other end of each branch 3320 is merged with each other, for example, sewn together. The extension 3330 extends from the merged ends of the branches 3320, and the extension 3330 can be directly connected to a vehicle (not shown). For example, the extension 3330 can be sewn to the merged position of the two branches 3320, and the end of the extension 3330 not connected to the branches 3320 can be provided with a connector (not shown) to connect to the seat of the vehicle (not shown); the end of the extension 3330 not connected to the two branches 3320 can also be first connected to other tethers (not shown), and then connected to a vehicle (not shown) through the other tethers.

[0388] Each branch 3320 is connected to the corresponding connection structure 3100 through a second connection member 3310, and the cover 3130 of the connection structure 3100 can cover the second connection member 3310, which will be described in detail below. Therefore, the interior of the connection structure 3100 and the second connection member 3310 are shielded by the cover 3130, providing a neat visual effect, while also preventing the exposed parts of the connection structure 3100 and the second connection member 3310 from causing unnecessary scratches, or preventing debris from entering the interior of the connection structure 3100 and affecting the normal use of the connection structure 3100.

[0389] In the present application, the child safety seat 3001 is fixed on the vehicle in a back-facing manner, that is, the back of the seat body 3200 faces the forward direction of the vehicle. Therefore, when the tether 3300 is connected to the seat of the vehicle, the child safety seat 3001 is stably fixed in the vehicle.

[0390] Moreover, in this embodiment, the tether 3300 extends in the longitudinal direction of the child safety seat 3001, and the second connector 3310 is connected to the connection structure 3100, for example, inserted into the connection structure 3100 in the transverse direction of the child safety seat 3001 (described in detail below). In the event of a vehicle collision, the tether 3300 is subjected to a large longitudinal tensile force. At this time, since the second connector 3310 is inserted into the connection structure 3100 in the transverse direction, the risk of it being separated from the connection structure 3100 under the action of the longitudinal tensile force can be reduced, and the connection stability between the connection structure 3100 and the second connector 3310 is increased, thereby improving the safety performance of the child safety seat 3001. It should be noted that the longitudinal extension of the tether 3300 in the child safety seat 3001 does not limit the tether 3300 to extend in the longitudinal direction in a completely straight form, but refers to that the overall shape of the tether 3300 is roughly extended in the longitudinal direction, and the tensile force direction of the tether 3300 is roughly in the longitudinal direction. For example, it can be understood that the strap 3300 is made of a flexible material, and when the strap 3300 extends from the connecting structure 3100 to the outside, the portion close to the connecting structure 3100 may undergo some deformation when extending outward because it needs to bypass other structures of the seat body 3200.

[0391] Reference Fig.43 The connection structure 3100 and the tether 3300 according to the present application are further described.

[0392] The connection structure 3100 includes a receiving portion 3110, a first connection member 3120, a cover 3130, a guide member 3140, and a reset member 3150. The lace 3300 includes a branch portion 3320 as described above and a second connection member 3310 connected to the branch portion 3320.

[0393] The receiving portion 3110 is mounted on the child safety seat 3001, for example, embedded in the side wing 3210 of the seat body 3200 (see FIG. Fig.38B In this embodiment, the accommodating portion 3110 is a separate component, and is assembled with the first connecting member 3120, the cover 3130 and other components to form an assembly before being installed on the child safety seat 3001. In other embodiments, the accommodating portion 3110 may also be integrally formed with the seat body 3200, for example, formed as a part of the side wing 3210 of the seat body 3200.

[0394] The first connecting member 3120 is arranged in the accommodating portion 3110 and can slide along a sliding direction D1 so as to switch between the locked position and the unlocked position. The cover body 3130 is arranged on the accommodating portion 3110 and can switch between the open position and the closed position relative to the accommodating portion 3110. In the present embodiment, the cover body 3130 is pivotally connected to the accommodating portion 3110, and thus pivots between the open position and the closed position. In other embodiments, the cover body 3130 can be a component that is slidably movable or detachable relative to the accommodating portion 3110. The reset member 3150 is used to bias the first connecting member 3120 toward the locked position. The guide member 3140 is used to slidably connect the first connecting member 3120 to the accommodating portion 3110 and guide the sliding direction D1 of the first connecting member 3120. The specific operation of the above-mentioned components will be described in detail later.

[0395] Reference Fig.44 The specific structure of the accommodation portion 3110 is described.

[0396] The accommodating portion 3110 includes an inner side surface 3113, four side walls, an extending wall 3112, a accommodating cavity 3118, and a mounting portion 3117, wherein the accommodating cavity 3118 has an opening 3119. For ease of description, the two side walls extending in the longitudinal direction among the four side walls are respectively referred to as the first side wall 3111a and the second side wall 3111b. In some embodiments, the accommodating portion 3110 may be an independent component installed on the child safety seat 3001, such as an independent shell, which is mounted to the carrier by bolts or welding. In other embodiments, the accommodating portion 3110 may be a portion integrally formed with the carrier, such as a recessed portion formed on the side of the child safety seat 3001. In this embodiment, as Fig.44 As shown, the receiving portion 3110 is an independent component installed on the child safety seat 3001, and the mounting portion 3117 and the carrier are fixed by fasteners such as bolts (not shown), so as to achieve the installation of the receiving portion 3110 to the carrier.

[0397] The inner side 3113 and the opening 3119 are opposite to each other. When the accommodating portion 3110 is mounted to the seat body 3200 of the child safety seat 3001 or formed as a part of the seat body 3200, the inner side 3113 is located inside the child safety seat 3001, and the opening 3119 faces the outside of the child safety seat 3001. In this embodiment, the four side walls of the accommodating portion 3110 are interconnected with the inner side 3113, wherein the first side wall 3111a and the second side wall 3111b extending in the longitudinal direction are opposite to each other, for example, opposite in the vertical direction, and the other two side walls are opposite to each other. Therefore, the accommodating portion 3110 is formed into a substantially rectangular box-shaped structure with one side open.

[0398] It should be noted that, in this embodiment, the accommodating portion 3110 can be an independent component installed on the child safety seat 3001, and it itself has four side walls; however, in other embodiments, the number of side walls can be adjusted, and in other embodiments, the number of side walls that the independent component itself has can be one, two or three. Therefore, when the accommodating portion 3110 is installed on the seat body 3220, it forms the accommodating portion 3110 with more side walls together with the parts on the seat body 3200, or the accommodating portion 3110 and its side walls are a structure formed by integral molding of the seat body 3200.

[0399] The extension wall 3112 extends from the inner side surface 3113 toward the opening 3119 to form a snap-fit ​​space 3112a and a clearance space 3112b. The snap-fit ​​space 3112a defines the insertion direction D2 of the second connector 3310, and the clearance space 3112b provides a space for the first connector 3120 to move to the locked position. When the first connector 3120 is in the locked position, the first connector 3120 is at least partially located in the clearance space 3112b. More specifically, the extension wall 3112 can be integrally formed with the inner side surface 3113, such as by injection molding. The extension wall 3112 surrounds and forms the snap-fit ​​space 3112a and the clearance space 3112b. The snap-fit ​​space 3112a is close to the unlocking position of the first connector 3120, and the clearance space 3112b is close to the locking position of the first connector 3120. The engaging space 3112a may be open at a side facing the unlocking position to allow the first connecting member 3120 to enter the engaging space 3112 (see FIG. Fig.49 It should be noted that, in other embodiments, the extension wall 3112 may not be provided to define the insertion direction of the second connector 3310 . For example, the insertion direction of the second connector 3310 may be defined by matching the shape of the second connector 3310 with the side wall of the receiving portion 3110 .

[0400] The first side wall 3111a and the second side wall 3111b are respectively provided with an axial hole 3114, and an open positioning recess 3115 and a closed positioning recess 3116 are provided around the axial hole 3114. Fig.45A and Fig.45B , which shows the specific structure of the cover body 3130.

The accommodating portion 3110 also includes a guide groove 3113a provided in the inner side surface 3113, and the guide groove 3113a corresponds to the position of the accommodating cavity 3118. The guide member 3140 limits the sliding direction D1 of the first connecting member 3120 through the guide groove 3113a (described in detail below), but it should be understood that in other embodiments, a guiding structure such as a guide rail, a limit block, etc. may also be provided in the accommodating cavity 3118 to limit the sliding direction D1 of the first connecting member 3120.

[0403] Reference Fig.46A and Fig.46B The specific structure of the first connecting member 3120 is described.

[0404] The first connecting member 3120 includes a hook portion 3121, a locking portion 3122, a pressing portion 3123, abutting portion 3124, a connecting hole 3125, and an inclined surface 3126. As described above, the first connecting member 3120 slides between the locked position and the unlocked position along the sliding direction D1. For ease of understanding, the structure of the first connecting member 3120 is described herein based on the directions of the locked position and the unlocked position.

[0405] The hook portion 3121 is close to the locking position and is configured to be connected to the first connecting member 3120. More specifically, the inner side (i.e. Fig.46A the right side) and the outer side (i.e. Fig.46A The left side of the connecting structure 3100 is provided with a clamping portion 3122 and a slope 3126. The clamping portion 3122 is configured as a groove that is recessed into the hook portion 3121 toward the outside, more specifically, as an elongated groove extending vertically. The slope 3126 is inclined toward the inner side of the hook portion 3121, so that the hook portion 3121 forms a triangular tip. As described below in conjunction with the operation of the connecting structure 3100, the function of the clamping portion 3122 is to hold the second connecting member 3310, and the function of the slope 3126 is to assist the second connecting member 3310 to be inserted into the connecting structure 3100. In the present embodiment, the shapes of the clamping portion 3122 and the slope 3126 are conducive to providing a compact structure, but in other embodiments, the clamping portion 3122 and the slope 3126 can also be configured in different forms, as long as the second connecting member 3310 can be held and the second connecting member 3310 can be assisted to be inserted into the connecting structure 3100.

[0406] The pressing portion 3123 is disposed on a side of the first connecting member 3120 adjacent to the opening 3119, and the pressing portion 3123 is close to the unlocking position. The pressing portion 3123 is configured to be pressed to move the first connecting member 3120 to the unlocking position. More specifically, the pressing portion 3123 is configured as a recessed portion and has a transversely extending wall near the unlocking position so that the user can operate the pressing portion 3123. In the present embodiment, the deformation direction of the reset member 3150 is along the longitudinal direction. After the user's finger enters the recessed portion, the user presses the wall along the longitudinal direction to operate the first connecting member 3120 to move to the unlocking position. It should be understood that the pressing portion 3123 can also be configured in other appropriate forms, such as a corrugated friction surface.

[0407] The connection hole 3125 is provided on the inner side surface 3113 ( Fig.46B The guide member 3140 is inserted into the connecting hole 3125 to limit the sliding direction D1 of the first connecting member 3120 (see Fig.49 In this embodiment, the guide member 3140 is a screw, the tail of which is connected to the connection hole 3125 and the head of which is stopped at one side of the guide groove 3113 a to prevent the first connection member 3120 from being separated from the accommodating cavity 3118 .

[0408] The two abutting portions 3124 are respectively arranged on both sides of the pressing portion 3123, and are used to limit the sliding range of the first connecting member 3120 and provide an abutting surface for the restoring member 3150, which will be described in detail below.

[0409] Reference Fig.47 The specific structures of the branch portion 3320 and the second connecting member 3310 of the tether 3300 are described.

[0410] The branch portion 3320 is, for example, a flexible braided belt, one end of which is connected to the second connector 3310. The second connector 3310 is specifically in the form of a buckle, which is, for example, a sheet of metal material, and the second connector 3310 is provided with a snap-fit ​​hole 3311. The snap-fit ​​hole 3311 is shaped to allow the hook portion 3121 of the first connector 3120 to pass through. In this embodiment, the snap-fit ​​hole 3311 is configured as an elongated hole, but in other embodiments, the snap-fit ​​hole 3311 may also be configured to be other shapes such as square, trapezoidal, elliptical, etc. to match the hook portion 3121 in different forms.

[0411] In this embodiment, the second connecting member 3310 is in the form of a buckle, but in other embodiments, the second connecting member 3310 may also be in the form of a hook, a mushroom head, a hanging ring, etc. The connection structure 3100 of the present application is applicable to various forms of second connecting members 3310. In particular, the shapes and connection relationships of the accommodating portion 3110 and the cover body 3130 are applicable to various forms of second connecting members 3310, and the form of the first connecting member 3120 can be changed accordingly according to the form of the second connecting member 3310.

[0412] Reference Fig.48A and Fig.48B , in which the relationship between the various components of the connection structure 3100 is more clearly shown.

[0413] The first connecting member 3120 is disposed in the accommodating cavity 3118 of the accommodating portion 3110, so that the pressing portion 3123 faces the outside of the accommodating portion 3110. The hook portion 3121 of the first connecting member 3120 is inserted into the engaging space 3112a of the accommodating portion 3110, and the reset member 3150 is disposed between the abutting portion 3124 of the first connecting member 3120 and the side wall of the accommodating portion 3110 to bias the first connecting member 3120 toward the locking position. The abutting portion 3124 provides a top abutting position for the reset member 3150, which can limit the reset member 3150. The reset member 3150 of this embodiment is a spring, and the abutting portion 3124 is provided with a protrusion 3124a (such as Fig.46B As shown in the figure, the protrusion 3124a can enter the spring to better locate the position of the spring. In the present embodiment, the first connecting member 3120 extends vertically, and the two reset members 3150 are arranged vertically on both sides of the pressing portion 3123. However, in other embodiments, more or fewer reset members 3150 can be provided, for example, only one reset member 3150 can be provided, which is located at the vertical center of the accommodating portion 3110 and abuts against the vertical middle position of the first connecting member 3120. In addition, in other embodiments, the number of the abutting portions 3124 can be adjusted, for example, only one abutting portion 3124 cooperates with one reset member 3150, or only one larger abutting portion 3124 cooperates with multiple reset members 3150 at the same time to limit the reset members 3150.

[0414] In addition, in this embodiment, at least a portion of the extension wall 3112 is located on one side of the abutting portion 3124 along the sliding direction D1 of the first connecting member 3120, and at least a portion of the extension wall 3112 is disposed opposite to the abutting portion 3124 along the sliding direction D1. When the first connecting member 3120 is located at the locking position, the abutting portion 3124 is close to or abuts against the extension wall 3112. Thus, when the first connecting member 3120 tends to rotate around the guide member 3140, at least a portion of the extension wall 3112 can resist the abutting portion 3124, thereby preventing the first connecting member 3120 from rotating around the guide member 3140 in the accommodating cavity 3118. Of course, in other embodiments, the outer peripheral wall of the connecting hole 3125 can be set as a non-circular wall (for example, an elliptical or polygonal wall) and extended into the guide groove 3113a, and the first connecting member 3120 can be restricted from rotating around the guide member 3140 in the accommodating cavity 3118 through the blocking matching relationship between the outer peripheral wall of the connecting hole 3125 and the guide groove 3113a.

[0415] Reference Figure 49 to Figure 53 The operation of the connection structure 3100 according to the present application is described.

[0416] exist Fig.49 In the state shown, the first connecting member 3120 is in the locked position, the cover 3130 is in the open position, and the second connecting member 3310 is outside the connecting structure 3100. At this time, the first connecting member 3120 is biased to the locked position by the reset member 3150. Since the cover 3130 is opened, the opening 3119 of the accommodating portion 3110 is open to the outside, so the second connecting member 3310 can be inserted into the accommodating portion 3110 through the opening 3119.

[0417] from Fig.49 Starting from the state shown in FIG. 1 , the user moves the second connecting member 3310 along the insertion direction D2 (i.e., the transverse direction of the present embodiment) toward the interior of the accommodating portion 3110, so that the second connecting member 3310 enters the engaging space 3112a and abuts against the inclined surface 3126 of the first connecting member 3120, reaching Fig.50 Status shown.

[0418] from Fig.50 Starting from the state shown in the figure, the user moves the second connecting member 3310 further into the interior of the accommodating portion 3110 along the insertion direction D2. When the second connecting member 3310 enters the connecting structure 3100, the second connecting member 3310 abuts against the inclined surface 3126, so that the first connecting member 3120, under the push of the second connecting member 3310, resists the pressure of the reset member 3150, temporarily leaves the locked position and moves toward the unlocked position, that is, reaches the unlocked position. Fig.51 Status shown.

[0419] from Fig.51 Starting from the state shown, since the first connecting member 3120 is at or near the unlocked position, it allows the second connecting member 3310 to continue to move along the insertion direction D2 toward the inside of the accommodating portion 3110. When the second connecting member 3310 enters the accommodating portion 3110, the engaging hole 3311 of the second connecting member 3310 corresponds to the position of the hook 3121, so that the first connecting member 3120 returns to the locked position under the action of the reset member 3150, and the hook 3121 passes through the engaging hole 3311 and reaches Fig.52 Status shown.

[0420] exist Fig.52 In the state shown, the second connecting member 3310 is held in the receiving portion 3110 by the first connecting member 3120. At this time, if the second connecting member 3310 is pulled by the branch portion 3320 of the lace 3300, the second connecting member 3310 moves outward relative to the receiving portion 3110 (i.e., moves in the opposite direction along the insertion direction D2), so that the second connecting member 3310 sinks into the engaging portion 3122 of the receiving portion 3110, as shown in FIG. Fig.53 Therefore, the second connecting member 3310 cannot leave the first connecting member 3120, but is stably held in the accommodating portion 3110 by the first connecting member 3120, thereby improving the safety performance of the connecting structure 3100.

[0421] When the second connecting member 3310 enters the accommodating portion 3110, the user can pivot the cover 3130 to the closed position so that the connecting structure 3100 reaches the closed position. Fig.54 When the cover 3130 is in the closed position, the cover 3130 shields the second connecting member 3310 in the connecting structure 3100. The branch portion 3320 of the tie 3300 extends to the outside of the connecting structure 3100 through the gap between the free end 3132 of the cover 3130 and the receiving portion 3110. Fig.54 The gap between the free end 3132 of the cover 3130 and the accommodating portion 3110 is drawn in an exaggerated manner. In fact, since the branch portion 3320 is made of flexible fabric, the gap can be so small that it is difficult to observe from the outside of the connection structure 3100. In this way, the cover 3130 shields the internal components of the connection structure 3100 and the second connecting member 3310, so that the connection structure 3100 has a neat appearance. It can be understood that the cover 3130 in the closed position has a certain limiting effect on the movement of the tether 3300, so that the tether 3300 extends closer to the outside of the seat body 3200.

[0422] The above describes the operation of locking the second connecting member 3310 to the connecting structure 3100. When the user needs to disengage the second connecting member 3310 from the connecting structure 3100, the above operation can be performed in reverse order. Specifically, the user first opens the cover 3130, and then presses the second connecting member 3310 toward the inside of the accommodating portion 3110 (i.e., presses along the insertion direction D2) to disengage the second connecting member 3310 from the engaging portion 3122 of the first connecting member 3120, and then moves the first connecting member 3120 to the unlocking position by operating the pressing portion 3123 to disengage the hook portion 3121 from the engaging hole 3311, and finally removes the second connecting member 3310 from the accommodating portion 3110. It should be understood that after removing the second connecting member 3310, the user can close the cover 3130 to restore the neat appearance of the connecting structure 3100 or prevent debris from entering the interior of the connecting structure 3100.

[0423] In summary, the present application provides a child safety seat having an openable and closable connection structure for connecting a tether, wherein the insertion direction of the tether is different from the pulling direction of the tether. The present application also provides a connection structure having a simple and compact structure, capable of stably locking a second connection member, and having a closable cover to provide a neat appearance.
