[0027] According to one embodiment of this application, such as Figures 1-4As shown, a child seat 100 is provided, including a seat body 10 and a tray assembly 20. The seat body 10 includes armrests 111. The tray assembly 20 includes a tray 21 and an adapter 22. The tray 21 is located at the top of the armrest 111, and the adapter 22 is located at the bottom of the tray 21. The adapter 22 is connected to the seat body 10. The bottom of the tray 21 has a snap-fit ​​hole 213. The adapter 22 includes a body portion 221 and a snap-fit ​​protrusion 222. The snap-fit ​​protrusion 222 is located on the body portion 221 and includes a first limiting portion 2221 and a second limiting portion 2222. At least a portion of the first limiting portion 2221 is located in the snap-fit ​​hole 213. Along the height direction Z of the seat body 10, the first limiting portion 2221 is engaged with the snap-fit ​​hole 213. The second limiting portion 2222 is located at the end of the first limiting portion 2221 that is away from the body portion 221. Along the first direction X, the second limiting portion 2222 is engaged with the tray 21. The first direction X is perpendicular to the height direction Z of the seat body 10.

[0028] The first direction X can be the same as or different from the front-back direction of the seat body 10.

[0029] The seat body 10 has a seat plate 112 and a backrest 113. The backrest 113 is connected to the rear end of the seat plate 112. The backrest 113 and the seat plate 112 can be integrally formed. The seat plate 112 is provided with armrests 111 (first armrest 1111 and second armrest 1112) on both sides along the second direction Y.

[0030] In one example, the adapter 22 has a guide groove 224 on the side facing the armrest 111, and the guide groove 224 is slidably connected to the armrest 111 along the front-back direction of the seat body 10. The armrest 111 has multiple slots spaced apart along the first direction X on one side along the second direction Y. The second direction Y, the first direction X, and the height direction Z are perpendicular to each other. The adapter 22 is threaded with screws, the ends of which can be inserted into the slots to fix the adapter 22. By inserting the screws into different slots, the position of the adapter 22 relative to the seat body 10 along the first direction X can be adjusted. In another example, multiple threaded holes spaced apart along the first direction X can also be provided on the armrest 111. The placement plate 21 or the adapter 22 is threaded with screws, which can engage with any of the threaded holes. This method can also achieve the adjustment of the position of the adapter 22 relative to the seat body 10 along the first direction X.

[0031] The structure formed by the first limiting part 2221 and the second limiting part 2222 can be an L-shaped bent rod or a buckle.

[0032] The placement tray 21 can be made of metal or plastic. When the placement tray 21 is made of plastic, it can be manufactured using an injection molding process.

[0033] The first limiting part 2221, the second limiting part 2222, and the main body part 221 can be integrally formed, or they can be connected by welding or bonding.

[0034] To prevent the placement tray 21 from scratching people, the parts of the placement tray 21 that come into contact with people can be made into rounded surfaces.

[0035] The number of snap-fit ​​protrusions 222 and snap-fit ​​holes 213 can be the same, specifically one or more.

[0036] The first limiting part 2221 is limited and engaged with the snap-fit ​​hole 213 along the height direction Z of the seat body 10, and the second limiting part 2222 is limited and engaged with the placement plate 21 along the first direction X. On the one hand, the snap-fit ​​protrusion 222 and the snap-fit ​​hole 213 are engaged. This snap-fit ​​engagement facilitates the disassembly and assembly of the adapter 22 and the placement plate 21. On the other hand, this snap-fit ​​engagement makes it difficult for the snap-fit ​​protrusion 222 to detach from the snap-fit ​​hole 213, thereby improving the reliability of the snap-fit ​​between the adapter 22 and the placement plate 21.

[0037] In some embodiments of this application, such as Figures 3-4 As shown, the bottom of the placement tray 21 is provided with a first reinforcing rib 211. Along the first direction X, the first reinforcing rib 211 is provided on one side of the adapter 22. Along the first direction X, a snap-fit ​​hole 213 is provided on one side of the first reinforcing rib 211. The snap-fit ​​hole 213 passes through the first reinforcing rib 211 along the first direction X. Along the first direction X, the second limiting part 2222 is limited and engaged with the first reinforcing rib 211.

[0038] The number of first reinforcing ribs 211 can be one or more. For example, first reinforcing ribs 211 can be provided on all four sides of the adapter 22 to provide installation space and positioning for the adapter 22.

[0039] The first reinforcing rib 211 can be integrally injection molded with the placement tray 21. This improves the strength of the placement tray 21 and reduces deformation caused by placing items. It also facilitates the setting of the snap-fit ​​hole 213. In other embodiments, a mounting groove can be provided at the bottom of the placement tray 21, the connector is placed in the mounting groove, and the side wall of the mounting groove is provided with snap-fit ​​holes 213. The snap-fit ​​protrusion 222 snaps into the side wall of the mounting groove.

[0040] In some embodiments of this application, such as Figures 1-4 As shown, the armrest 111 includes a first armrest 1111 and a second armrest 1112. The first armrest 1111 and the second armrest 1112 are spaced apart along the second direction Y. The first armrest 1111 and the second armrest 1112 are respectively connected to a connector 22. Each connector 22 has a corresponding snap-fit ​​protrusion 222 with a snap-fit ​​hole 213. The second direction Y is perpendicular to the first direction X and the height direction Z of the seat body 10.

[0041] The first handrail 1111 and the second handrail 1112 can be symmetrically arranged along the second direction Y, and the distance between the two along the second direction Y matches the distance between the two adapters 22 along the second direction Y.

[0042] For ease of description, the adapter 22 connected to the first armrest 1111 is the first adapter, and the adapter 22 connected to the second armrest 1112 is the second adapter. The connection method between the first armrest 1111 and the first adapter can be the same as, different from, or partially the same as the connection method between the second armrest 1112 and the second adapter. For example, the first armrest 1111 and the first adapter can be fixed by snap-fit, and multiple snap-fit ​​structures spaced apart along the first direction X can be provided on their corresponding mating surfaces to achieve snap-fit ​​at different positions. The second armrest 1112 has multiple threaded holes spaced apart along the first direction X, and the second adapter has screws. The screws can be threaded into any threaded hole to adjust the position of the placement plate 21 relative to the seat body 10 along the first direction X. This method simplifies the trouble of adjusting screws and improves the convenience of operation.

[0043] The first armrest 1111 and the second armrest 1112 are respectively connected to the adapter 22, which allows the placement tray 21 to be installed more stably on the seat body 10, thereby increasing its stability.

[0044] In some embodiments of this application, such as Figures 1-4 As shown, the armrest 111 includes a first armrest 1111 and a second armrest 1112. The first armrest 1111 and the second armrest 1112 are spaced apart along the second direction Y. The tray assembly 20 also includes a protective member 23 connected to the bottom of the tray 21. The protective member 23 is disposed between the first armrest 1111 and the second armrest 1112 along the second direction Y. The protective member 23 has a blocking portion 231 extending along the height direction Z of the seat body 10. The blocking portion 231 is used to prevent infants and young children from sliding off the seat body 10. The second direction Y is perpendicular to the first direction X and the height direction Z of the seat body 10.

[0045] In one example, the protective member 23 includes a connecting portion 232 extending along the second direction Y. The blocking portion 231 has connecting portions 232 on both sides along the second direction Y. Each connecting portion 232 can be connected to the placement tray 21 by a fastener, specifically by screws threaded onto the placement tray 21. The connecting portion 232 can also be connected to the placement tray 21 by bonding, welding, or snap-fitting. The adapter 22 also includes a crimping portion 223 extending along the second direction Y. The connecting portion 232 can press the crimping portion 223 onto the bottom of the placement tray 21, thus further improving the robustness between the adapter 22 and the placement tray 21.

[0046] The blocking part 231 of the protective component 23 can be located at the middle of the first handrail 1111 and the second handrail 1112 along the second direction Y, and located near the front end of the placement plate 21.

[0047] The blocking part 231 prevents infants and young children from sliding off the seat body 10, thereby improving safety during use.

[0048] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the top of the placement tray 21 is provided with a groove 214 for placing items, and the bottom of the placement tray 21 is provided with a first plane 216. The first plane 216 is provided with a protrusion 215. Along the height direction Z of the seat body 10, the groove 214 extends into the protrusion 215. The protrusion 215 is provided with at least one second reinforcing rib 212 on both sides along the second direction Y. The second direction Y is perpendicular to the first direction X and the height direction Z of the seat body 10.

[0049] The groove 214 can be used to place plates, books or other items to prevent them from slipping off the plate 21.

[0050] A second reinforcing rib 212 may be provided around the perimeter of the protrusion 215. When the distance between the side of the protrusion 215 along the first direction X and one end of the placement plate 21 along the first direction X is small, the second reinforcing rib 212 may not be provided.

[0051] The second reinforcing rib 212 can be integrally formed with the placement tray 21, or it can be fixed to the placement tray 21 by welding or bonding.

[0052] The second reinforcing rib 212 can improve the overall strength of the placement tray 21, thereby reducing the large deformation of the placement tray 21 caused by placing items in the groove 214 and improving the reliability of the placement tray 21.

[0053] In some embodiments of this application, such as Figure 2 As shown, the protrusion 215 is provided with a plurality of second reinforcing ribs 212 on both sides along the second direction Y, and the plurality of second reinforcing ribs 212 on the same side of the protrusion 215 along the second direction Y are spaced apart along the first direction X.

[0054] This can further improve the overall strength of the placement tray 21, thereby reducing the large deformation of the placement tray 21 caused by placing items in the groove 214 and improving the reliability of the placement tray 21 in use.

[0055] In some embodiments of this application, such as Figure 1 , Figures 5-8As shown, the child seat 100 also includes a wheel assembly 30, which includes a wheel seat 31 and a wheel 32. The wheel seat 31 is located at the bottom of the seat body 10 along the height direction Z of the seat body 10. The wheel seat 31 has a first connecting end and a second connecting end spaced apart from each other. The first connecting end has a snap-fit ​​protrusion 311. The bottom of the seat body 10 has a snap-fit ​​hole 123 that engages with the snap-fit ​​protrusion 311. A support rib 312 is connected to the side of the snap-fit ​​protrusion 311 opposite to the snap-fit ​​hole 123. The second connecting end is connected to the seat body 10. The wheel 32 is rotatably connected to the wheel seat 31, and the axis of rotation of the wheel 32 relative to the wheel seat 31 is perpendicular to the first direction X and the height direction Z of the seat body 10, respectively. The support rib 312 is integrally formed with the wheel seat 31, or the support rib 312 is connected to the wheel seat 31.

[0056] The connection methods between the second connecting end and the seat body 10 include, but are not limited to, welding, screw connection, bonding or snap-fit.

[0057] The snap-fit ​​protrusion 311 and the wheel seat 31 can be integrally formed, or they can be fixed to the wheel seat 31 by welding or bonding.

[0058] The snap-fit ​​protrusion 311 and the support rib 312 can be integrally formed, or they can be fixed by welding or bonding.

[0059] The traveling wheel 32 can be rotatably connected to the wheel seat 31 via the rotating shaft 33.

[0060] The first connecting end can be located above the second connecting end, or the first connecting end can be located below the second connecting end.

[0061] During travel, the wheel 32 may vibrate due to uneven road surfaces, which could easily cause the locking protrusion 311 to break. By setting the support rib 312, the possibility of the locking protrusion 311 breaking due to vibration can be reduced, thereby improving the reliability of the connection between the wheel seat 31 and the seat body 10.

[0062] In some embodiments of this application, such as Figure 6 As shown, there are multiple support ribs 312, which are spaced apart along the first direction X.

[0063] This can further reduce the possibility of breakage of the snap-fit ​​protrusion 311 and improve the reliability of the connection between the snap-fit ​​protrusion 311 and the wheel seat 31.

[0064] In some embodiments of this application, such as Figure 1 As shown, the front end of the seat body 10 is provided with two sides along the second direction Y, and / or the rear end of the seat body 10 is provided with two sides along the second direction Y, respectively.

[0065] When both the front and rear sides of the seat body 10 along the second direction Y are provided with wheel assemblies 30, the child seat 100 can be moved by pushing it directly. When only one of the front and rear sides of the seat body 10 along the second direction Y is provided with wheel assemblies 30, the front or rear side of the child seat 100 can be lifted and moved, reducing the force required to move the child seat 100 and thus facilitating its movement.

[0066] In some embodiments of this application, such as Figure 1 , Figures 5-8 As shown, the seat body 10 includes a seat body 11 and a support frame 12. The seat body 11 includes armrests 111. The support frame 12 is located at the bottom of the seat body 11 and connected to the seat body 11. The bottom of the support frame 12 is provided with a locking hole 123, and a second connecting end is connected to the support frame 12.

[0067] The aforementioned seat plate 112 and backrest 113 constitute the seat body 11.

[0068] The second connecting end is connected to the support frame 12 by means of, but not limited to, screw connection, welding or snap-fit.

[0069] In one example, the support frame 12 is provided with a first connecting hole 124, and the second connecting end is provided with a second connecting hole 313. The end of the screw passes through the second connecting hole 313 and is threadedly connected to the first connecting hole 124.

[0070] By setting up the support frame 12, the seat body 10 is made smaller during injection molding, reducing the difficulty and cost of injection molding. At the same time, the weight of the seat body 10 can also be reduced, which helps to reduce the manufacturing cost of the child seat 100.

[0071] In some embodiments of this application, such as Figure 1 , Figures 5-8 As shown, the support frame 12 includes a front support 121 and a rear support 122. The front support 121 and the rear support 122 are spaced apart along the first direction X. Both the front support 121 and the rear support 122 are located at the bottom of the base 11 and are connected to the base 11 respectively. The front support 121 has wheel assemblies 30 on both sides along the second direction Y, and a locking hole 123 at the bottom of the front support 121, with a second connecting end connected to the front support 121; and / or, the rear support 122 has wheel assemblies 30 on both sides along the second direction Y, and a locking hole 123 at the bottom of the rear support 122, with a second connecting end connected to the rear support 122.

[0072] Both the front support 121 and the rear support 122 can be made by bending the tubing, and can be generally set into an approximately U-shaped structure.

[0073] The front support 121 and the rear support 122 respectively bear the weight of the front and rear parts of the seat body 11, and then transfer it to the ground through the walking wheel assemblies 30 on both sides. This avoids the weight being concentrated in one area, reduces the stress on the local structure, and extends the overall life of the seat. In addition, the front support 121 and the rear support 122 are separate structures, which facilitates assembly with the seat body 11.
