Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to children's vehicles. Background Technology

[0002] To enhance safety, child vehicles, such as child safety seats, are typically used when transporting children in a vehicle. Some child vehicles (such as Booster-type child safety seats) can switch between a high-back mode with a backrest and a no-back mode. In the no-back mode, the child is restrained by the vehicle's seatbelt, and a cross-traffic switch on the child vehicle further restrains the seatbelt to ensure a better fit between the seatbelt and the child's shoulders. In high-back mode, the child vehicle uses its own built-in seatbelt for restraint, and this mode does not require the cross-traffic switch.

[0003] When traditional child vehicles are used in high-back mode, their cross-traffic obstacle components may be placed rather haphazardly, affecting the neatness of the vehicle and making it prone to tangling with other parts. Additionally, the impact protection performance of the side wings of the backrest in traditional child vehicles needs improvement. Utility Model Content

[0004] According to one aspect of the present invention, a child vehicle is provided. The child vehicle includes a seat body and a crosswalk assembly. The seat body includes a backrest assembly and a seat assembly, which are detachably connected. The crosswalk assembly is adapted to limit the seat belt of the vehicle.

[0005] The seat assembly has a receiving section at its rear, the overpass assembly is connected to the receiving section, the receiving section has a receiving slot, the receiving slot is adapted to at least partially accommodate the overpass assembly, and the connection point between the overpass assembly and the receiving section is located outside the receiving slot.

[0006] In one embodiment, the opening of the receiving slot faces rearward, and the connection point is located above or below the receiving slot.

[0007] In one embodiment, the receiving portion is provided with a threading groove and a limiting portion, the limiting portion being disposed between two opposite sidewalls of the threading groove and defining a connection point. The road crossing assembly includes a road crossing and a connecting strip connected to the road crossing, the connecting strip being provided with a connecting end adapted to be stopped by the limiting portion to detachably connect the connecting strip to the limiting portion.

[0008] In one embodiment, the receiving portion is further provided with a connecting wall, which is connected to the two side walls of the threading groove. The connecting wall has a first end near the receiving groove and a second end opposite to the first end, with one of the first and second ends forming a limiting portion; or, the side of the connecting wall facing the bottom of the threading groove has a protrusion extending towards the bottom of the groove, the protrusion forming a limiting portion; or, the connecting wall has a connecting opening communicating with the threading groove, the portion of the connecting wall near the connecting opening forming a limiting portion, and the connecting belt being adapted to pass through the connecting opening.

[0010] In one embodiment, the road crossing assembly includes a road crossing and a connecting strip connected to the road crossing. When the connecting strip is wrapped around the road crossing and inserted into the receiving slot together with the road crossing, the connecting strip wrapped around the road crossing abuts against the side wall of the receiving slot, thereby pressing and securing the road crossing within the receiving slot.

[0011] In one embodiment, the roadway includes a connecting hole and a guide channel. The connecting hole is elongated and extends generally along a first direction. The guide channel communicates with the connecting hole to guide the vehicle's seatbelt into or out of the connecting hole. The guide channel extends linearly at an angle to the direction of extension of the connecting hole; alternatively, the guide channel extends along a curve.

[0012] In one embodiment, the child vehicle further includes a connecting assembly and an adjusting assembly. The connecting assembly includes a connector and an adjusting strap, the adjusting strap being adjustably threaded through the seat assembly, and the connector being connected to the adjusting strap. The adjusting assembly includes an adjusting member movably disposed on the seat assembly and switchable between a locked position and an unlocked position. When the adjusting member is in the locked position, the adjusting strap is restricted from moving relative to the seat assembly in a predetermined direction; when the adjusting member is in the unlocked position, the adjusting strap is allowed to move relative to the seat assembly in a predetermined direction.

[0013] In one embodiment, the adjusting member includes a pivot portion and an operating portion connected to the pivot portion. The pivot portion is pivotally connected to the seat assembly, and a first serrated portion and a clearance portion are provided on the outer periphery of the pivot portion. The seat assembly is provided with a second serrated portion. When the adjusting member is in the locked position, the first serrated portion and the second serrated portion are adapted to abut against both sides of the adjusting belt, respectively. When the adjusting member is in the unlocked position, the first serrated portion is offset from the adjusting belt, and the clearance portion is opposite to the second serrated portion, so as to allow the adjusting belt to move in a predetermined direction.

[0014] In the child vehicle provided by this utility model, the user can conveniently store the crosswalk assembly in the receiving slot or remove the crosswalk assembly from the receiving slot. Furthermore, by placing the connection point between the crosswalk assembly and the receiving part on the outside of the receiving slot, rather than inside, the child vehicle of this embodiment allows the user to easily check or adjust the connection between the connecting strap and the receiving part.

[0015] According to another aspect of the present invention, a child carrier is provided. The child carrier includes a backrest assembly. The backrest assembly includes a backrest body and side wings disposed at both ends of the backrest body. Each side wing includes a side wing body and a cushioning structure. The cushioning structure includes a cushioning shell and a cushioning portion. The cushioning shell is connected to the side wing body and forms a cushioning cavity with the side wing body. The cushioning portion is laterally disposed within the cushioning cavity.

[0016] In one embodiment, each side wing portion further includes a front wall disposed on the side of the side wing main body away from the backrest main body, the front wall and the side wing main body portion being disposed at an angle and forming a recess, the buffer housing being disposed in the recess and also connected to the front wall, and the buffer cavity extending from the front wall toward the direction close to the backrest main body.

[0017] In one embodiment, the buffer section includes reinforcing ribs arranged laterally within the buffer cavity, and the reinforcing ribs are wavy.

[0018] In one embodiment, the buffer cavity has an opening through the front wall and a bottom wall opposite the opening, and the buffer portion extends in the front-rear direction to the opening and the bottom wall of the buffer cavity, respectively.

[0019] In one embodiment, the buffer structure further includes a connecting rib, which is connected to the outer side surface of the buffer housing and the main body of the side wing, and the connecting rib extends toward the backrest body.

[0020] The buffer structure provided by this utility model can effectively buffer the external impact force that the side wings may bear, especially the lateral impact force, and reduce the possibility of the backrest component breaking under the action of external impact force, thereby better protecting children riding in child vehicles.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Figure 1 A perspective view of a child vehicle according to an embodiment of the present invention is shown. The child vehicle may be, for example, a child safety seat, but is not limited thereto. The following description uses a Booster-type child safety seat as an example.

[0041] See Figure 1 and Figure 2 The child vehicle may include a seat body 100 and a cross-traffic device assembly 200. The seat body 100 may include a backrest assembly 110 and a seat assembly 120, which may be detachably connected. The cross-traffic device assembly 200 may be connected to the seat assembly 120 and may be adapted to limit the vehicle's seat belt 13. The child vehicle may have a high-back mode for use with the backrest assembly 110 (see...). Figure 1 ) and the NoBack mode used with the backless component 110 (see Figure 3 ). Combination Figure 6 As shown, when the child vehicle is in backless mode, that is, when the seat assembly 120 is installed alone on the vehicle seat 10, the child needs to be restrained on the seat assembly 120 using the seat belt 13 provided on the vehicle seat 10. In this mode, the crossbar assembly 200 can be used in conjunction with the seat belt 13, for example, by connecting the crossbar assembly 200 to the seat belt 13, thereby restraining the seat belt 13 and adjusting the relative position of the seat belt 13 and the child, so that the car seat belt fits the child's shoulder better. When the child vehicle is in high-back mode, that is, when the backrest assembly 110 and the seat assembly 120 are connected together and installed on the vehicle seat, the child can be restrained on the seat assembly 120 using the seat belt (not shown) provided with the child vehicle. That is to say, in high-back mode, there is no need to adjust the crossbar assembly 200, and the crossbar assembly 200 can be idle.

[0042] See Figure 1 and Figure 3 The seat assembly 120 may be provided with a receiving portion 300, which may be located generally at the rear of the seat assembly 120, i.e., on the side of the seat assembly 120 suitable for connection with the backrest assembly 110. A crosswalk assembly 200 may be connected to the receiving portion 300. Specifically, the crosswalk assembly 200 is detachably connected to the receiving portion 300 to facilitate replacement and cleaning of the crosswalk assembly 200. The crosswalk assembly 200 may include a connecting belt 220 and a crosswalk 210. The connecting belt 220 may be connected to the receiving portion 300. The crosswalk 210 is movably disposed on the connecting belt 220 to adjust the relative position of the crosswalk 210 in the length direction of the connecting belt 220, thereby adjusting the effective length of the connecting belt 220. Specifically, the connecting belt 220 may pass through the crosswalk 210 and may be detachably connected to the receiving portion 300.

[0043] It should be understood that the effective length of the connecting strip 220 refers to the length of the connecting strip 220 from the connection point between the connecting strip 220 and the receiving part 300 to the crossbar 220.

[0044] The receiving section 300 may be provided with a receiving slot 310, which is adapted to at least partially accommodate the crossover assembly 200. The receiving slot 310 may be located near the connection point between the crossover assembly 200 and the receiving section 300, that is, the receiving slot 310 may be located close to the connection point between the connecting strip 220 and the receiving section 300. This connection point may be located outside the receiving slot 310, rather than inside the receiving slot 310, so as to facilitate the user to check or adjust the connection between the connecting strip 220 and the receiving section 300. Specifically, the receiving slot 310 may be located immediately adjacent to the connection point between the crossover assembly 200 and the receiving section 300, and the receiving slot 310 may be located above or below the connection point, that is, the connection point may be located below or above the receiving slot 310. This makes it very convenient to store the crossover assembly 200 in the receiving slot 310 or to remove the crossover assembly 200 from the receiving slot 310. Optionally, when the crosswalk assembly 200 is not needed, such as when the child vehicle is in high-back mode, the connecting strap 220 can be partially wrapped around the crosswalk 210 without removing it from the receiving section 300. Then, the crosswalk 210, along with the connecting strap 220, can be inserted into the receiving slot 310. This way, the connecting strap 220 can be used to press and secure the crosswalk 210 into the receiving slot 310, making it less likely for the crosswalk 210 to come loose from the receiving slot 310. Of course, in this case, the connecting strap 220 can also be removed from the receiving section 300 first, and then wrapped around the crosswalk 210 and inserted into the receiving slot 310 together. This invention does not limit this approach. When the child vehicle is in backless mode, the crossbar 210 and the connecting strap 220 wrapped around it can be removed from the receiving slot 310 for use.

[0045] See Figure 2 and Figure 6The road crossing 210 may include a road crossing body 219. The road crossing body 219 may be, for example, plate-shaped or sheet-shaped. Optionally, the road crossing body 219 may be, for example, a one-piece molded component, but is not limited thereto. The road crossing 210 may include a connection hole 211 and a guide channel 213 disposed through the road crossing body 219. The guide channel 213 may have two open ends. One open end 2131 (also referred to as the first open end 2131) of the guide channel 213 may communicate with the connection hole 211, and the other open end 2132 (also referred to as the second open end 2132) may be located at the outer edge of the road crossing body 219. The guide channel 213 may be adapted to guide the vehicle's seat belt 13 into or out of the connection hole 211, so that the road crossing 210 can be detachably connected to the seat belt 13 and can move relative to the seat belt 13. The connecting hole 211 can be generally elongated and can extend along the first direction D1. The length of the connecting hole 211 can be adapted to the width of the seat belt 13. That is, the size of the connecting hole 211 in the first direction D1 can be greater than or equal to the width of the seat belt 13, so as to avoid the seat belt 13 being twisted or deformed due to being restricted by the end of the connecting hole 211.

[0046] See also Figure 1 and Figure 2 The crossover 210 may also be provided with two threading holes 212. The two threading holes 212 can respectively penetrate the crossover body 219. The two threading holes 212 can be generally elongated. For example, the extending direction of the two threading holes 212 can be generally parallel to the extending direction of the connecting hole 211 (i.e., the first direction D1), but is not limited thereto. The length of each threading hole 212 can be adapted to the width of the connecting strip 220, that is, the length of each threading hole 212 can be greater than or equal to the width of the connecting strip 220. The connecting strip 220 can be movably threaded through the two threading holes 212. Specifically, the connecting strip 220 can enter one of the threading holes 212 from one side (i.e., the insertion side) of the crossover 210, pass through the other side (i.e., the exit side) of the crossover 210, then enter the other threading hole 212 from the exit side, and finally exit from the insertion side. This arrangement increases the friction between the connecting belt 220 and the crossbar 210, preventing them from separating during use. It also allows for easy adjustment of the relative position of the crossbar 210 along the length of the connecting belt 220, thereby adjusting the effective length of the connecting belt 220.

[0047] When using the crossover assembly 200, the seat belt 13 can be guided through the guide channel 213 into the connection hole 211. Specifically, one side of the seat belt 13 in the width direction can be placed into the guide channel 213, and then the seat belt 13 can be passed through the guide channel 213 into the connection hole 211. Then, the position of the crossover 210 on the seat belt 13 can be adjusted, and the effective length of the connecting strap 220 can be adjusted according to the position of the crossover 210 on the seat belt 13, so that the seat belt 13 fits more snugly against the child's shoulder. This allows the seat belt 13 of the vehicle seat 10 to provide protection for children of different heights, improving the compatibility of the seat belt 13.

[0048] See Figure 1 and Figure 2 The two open ends of the guide channel 213 may be offset from each other in a second direction D2, wherein the second direction D2 is approximately perpendicular to the first direction D1. That is, the angle between the line connecting the two open ends 2131 and 2132 of the guide channel 213 and the second direction D2 may be approximately acute. In other words, at least a portion of the projections of the two open ends 2131 and 2132 of the guide channel 213 onto a plane perpendicular to the second direction D2 may not overlap. This effectively prevents the seat belt 13 from accidentally slipping out of the connection hole 211. Optionally, the guide channel 213 may be, for example, approximately L-shaped, straight, or inclined S-shaped, but is not limited thereto. In this embodiment, the guide channel 213 may have a pair of opposing inner walls, which may be curved and extended respectively; specifically, the pair of inner walls may be approximately inclined S-shaped respectively.

[0049] The main body 219 of the road crossing may have a first connecting portion 2191 and a second connecting portion 2192. The first connecting portion 2191 and the second connecting portion 2192 may be disposed opposite to each other. A guide channel 213 may be formed between the first connecting portion 2191 and the second connecting portion 2192. The ends of the first connecting portion 2191 and the second connecting portion 2192 may respectively form a pair of inner walls of the guide channel 213. The first connecting portion 2191 may have a first recess 2191a and a first protrusion 2191b. The first recess 2191a is further away from the connecting hole 211 than the first protrusion 2191b. The second connecting portion 2192 may have a second recess 2192a and a second protrusion 2192b. The second protrusion 2192b is further away from the connecting hole 211 than the second recess 2192a. The first protrusion 2191b can protrude toward the second recess 2192a, and a first opening end 2131 of the guide channel 213 can be formed between the first protrusion 2191b and the second recess 2192a. The second protrusion 2192b can protrude toward the first recess 2191a, and a second opening end 2132 of the guide channel 213 can be formed between the second protrusion 2192b and the first recess 2191a. The first protrusion 2191b and the second protrusion 2192b can be spaced apart and can form the middle of the guide channel 213. Specifically, the projections of the first protrusion 2191b and the second protrusion 2192b on a plane perpendicular to the second direction D2 can at least partially overlap. In this way, when the road crossing 210 is connected to the seat belt 13 for use, the first protrusion 2191b and the second protrusion 2192b can be used to stop the seat belt 13, preventing the seat belt 13 from accidentally coming out of the connection hole 211. Optionally, the widths of the two open ends 2131 and 2132 of the guide channel 213 can be greater than the width of the middle part of the guide channel 213. Because the two open ends 2131 and 2132 of the guide channel 213 are wider, the time required for alignment can be reduced when the seat belt 13 is threaded into or out of the connecting hole 211 along the guide channel 213, thus reducing the difficulty of aligning the seat belt 13 with the guide channel 213 and improving efficiency. Furthermore, because the middle part of the guide channel 213 is narrower, it can further prevent the seat belt 13 from accidentally slipping out of the connecting hole 211 through the guide channel 213.

[0050] In an embodiment not shown, the two open ends 2131, 2132 of the guide channel 213 can be substantially aligned in the second direction D2, that is, the line connecting the two open ends of the guide channel 213 can be substantially parallel to the second direction D2. The guide channel 213 can be, for example, substantially C-shaped or U-shaped, and the pair of inner walls of the guide channel 213 can be substantially C-shaped or U-shaped respectively.

[0051] Combination Figure 1 , Figure 3 and Figure 6As shown, the opening of the receiving slot 310 can face approximately rearward, meaning the opening of the receiving slot 310 can be located on the side of the receiving part 300 facing the backrest surface 11 of the vehicle seat 10. When it is necessary to remove or put back the road device assembly 200 from the receiving slot 310, simply move the seat assembly 120 a certain distance away from the backrest surface 11 of the vehicle seat 10 to remove or put back the road device assembly 200 without removing the seat cloth or cushion (not shown) covering the seat assembly 120. This makes it easier to retrieve and put back the road device assembly 200.

[0052] See Figure 1 , Figure 3 , Figure 7 and Figure 10 In some embodiments, the receiving portion 300 may be provided with a threading groove 320 and a limiting portion 330. One end of the threading groove 320 may communicate with the receiving groove 310, and the other end is an open end. The threading groove 320 may be located above or below the receiving groove 310. In this embodiment, the opening of the threading groove 320 may face approximately rearward, and the threading groove 320 may extend approximately in the vertical direction. Of course, the threading groove 320 may also be inclined relative to the vertical direction according to the actual use needs. The threading groove 320 may have a groove bottom 321 and two oppositely arranged side walls. The limiting portion 330 may be disposed between the two side walls of the threading groove 320 and may be spaced apart from the groove bottom 321 of the threading groove 320. The limiting portion 330 may be adapted to stop a portion of the connecting strip 220 and may define the connection point between the connecting strip 220 and the receiving portion 300.

[0053] The connecting strap 220 may have a strap body 222 and a connecting end 221. The connecting end 221 may be disposed at one end of the strap body 222. The connecting end 221 may be adapted to be stopped by the limiting portion 330, so that the connecting strap 220 is connected at the limiting portion 330. Figure 1 , Figure 7 and Figure 10As shown, the connecting end 221 may be, for example, generally bow-shaped. The connecting end 221 may have a first portion 2211 and a second portion 2212. One end of the first portion 2211 may be connected to or integrally formed with the belt body 222, and the other end of the first portion 2211 may be connected to the second portion 2212. Specifically, the other end of the first portion 2211 may be connected to approximately the middle of the second portion 2212. The connecting end 221 may have an unfolded state and a non-unfolded state. When the connecting end 221 is in the unfolded state, an angle may be formed between the first portion 2211 and the second portion 2212, that is, the first portion 2211 and the second portion 2212 may extend in different directions, so that at least a portion of the limiting portion 330 can be stopped between the first portion 2211 and the second portion 2212. When the connecting end 221 is in the non-deployed state, the first part 2211 and the second part 2212 can overlap each other, thereby preventing the connecting end 221 from being blocked by the limiting part 330, that is, allowing the connecting end 221 to pass over the limiting part 330. This allows the connecting strap 220 to be removed from the strap slot 320 or the limiting part 330, or the connecting strap 220 to be installed at the strap slot 320 or the limiting part 330. In this embodiment, the connecting end 221 can conveniently achieve a detachable connection between the connecting strap 220 and the receiving part 300, thereby facilitating the replacement and cleaning of the connecting strap 220.

[0054] See Figure 1 , Figure 3 , Figure 7 and Figure 10 The receiving portion 300 may be provided with a connecting wall 340. This connecting wall 340 may be connected to two side walls of the threading groove 320 respectively, and may at least partially cover the opening of the threading groove 320. Optionally, the limiting portion 330 may be integrally formed with the wall of the threading groove 320; or, the limiting portion 330 may be connected to the side wall of the threading groove 320 by means of threaded connection, bonding, or welding.

[0055] See Figure 1 , Figure 3 and Figure 7In some embodiments, the connecting wall 340 may partially cover the opening of the threading groove 320. The connecting wall 340 may have a first end 342 near the receiving groove 310 and a second end 343 opposite to the first end 342. One of the first end 342 and the second end 343 may form a limiting portion 330. The connecting strap 220 may be threaded through the threading groove 320. The connecting end 221 of the connecting strap 220 may be adapted to be stopped by the limiting portion 330. The portion of the threading groove 320 corresponding to the connecting end 221 may be formed as a clearance groove 322. Exemplarily, the first end 342 of the connecting wall 340 may be formed as the limiting portion 330. The limiting portion 330 may be spaced apart from the receiving groove 310 in the extending direction of the threading groove 320 and may be located above or below the receiving groove 310. The portion of the threading groove 320 located between the limiting portion 330 (i.e., the first end 342) and the receiving groove 310 can be formed as a clearance groove 322. The connecting belt 220 can pass through the threading groove 320 from bottom to top, and the connecting end 221 of the connecting belt 220 can be adapted to be blocked by the limiting portion 330 and at least partially accommodated in the clearance groove 322. In this way, on the one hand, the connecting end 221 can protrude less or even not protrude from the outer side of the receiving portion 300, making the receiving portion 300 more concise and aesthetically pleasing; on the other hand, it can reduce the space occupied by the connecting end 221 of the connecting belt 220 in the receiving groove 310, thereby facilitating the storage of the road crossing device 210 and the connecting belt 220 wrapped around it in the receiving groove 310. Alternatively, the second end 343 of the connecting wall 340 can be formed as a limiting portion 330, and the portion of the strap groove 320 located on the side of the limiting portion 330 (i.e., the second end 343) away from the receiving groove 310 can be formed as a clearance groove 322. Specifically, the portion of the strap groove 320 located above the limiting portion 330 can be formed as a clearance groove 322. The connecting strap 220 can pass through the strap groove 320 from top to bottom, and the connecting end 221 of the connecting strap 220 can be adapted to be blocked by the limiting portion 330 and at least partially accommodated in the clearance groove 322.

[0056] In some other embodiments, the connecting wall 340 may have a protrusion (not shown) extending toward the bottom 321 of the groove 320 (i.e., the inner side of the connecting wall 340) on the side facing the bottom 321 of the groove 320. This protrusion may be formed as a limiting part 330.

[0057] See Figure 10 In another embodiment, the connecting wall 340 may be provided with a connecting opening 341. This connecting opening 341 may be a through hole penetrating the connecting wall 340. The portion of the connecting wall 340 immediately adjacent to the connecting opening 341 may be formed as a limiting portion 330. The connecting strap 220 may pass through the connecting opening 341, and the connecting end 221 of the connecting strap 220 may be adapted to be stopped by the limiting portion 330. Optionally, as... Figure 10As shown, the end of the connecting strap 220 away from the connecting end 221 (i.e., the free end of the connecting strap 220) can pass through the connecting opening 341, and the connecting end 221 can be blocked by the outer side of the limiting part 330 (i.e., the outer side of the connecting wall 340); or, the free end of the connecting strap 220 can pass through the connecting opening 341, and the connecting end 221 can be blocked by the inner side of the limiting part 330 (i.e., the inner side of the connecting wall 340).

[0058] In some embodiments not shown, the receiving portion 300 may not have a connecting wall 340. For example, a connecting rod (not shown) may be provided between the two side walls of the threading groove 320, and the connecting rod may be formed as a limiting portion 330; or, at least one of the two side walls of the threading groove 320 may have a protrusion (not shown) extending toward the other of the two side walls of the threading groove 320, and the protrusion may be formed as a limiting portion 330.

[0059] According to the embodiments of the present invention, the child vehicle can be conveniently accessed by connecting the cross-pass assembly 200 to the receiving portion 300 provided on the rear side of the seat assembly 120, and providing a receiving slot 310 near the connection point between the cross-pass assembly 200 and the receiving portion 300. Specifically, when the child vehicle is in high-back mode, the cross-pass assembly 200 can be conveniently placed in the receiving slot 310, making the child vehicle neater and more organized. This avoids the cross-pass assembly 200 getting tangled in other parts and prevents it from colliding with people or other objects in the vehicle during sharp turns, sudden braking, or accidents, thereby reducing the possibility of secondary injuries. When the child vehicle is in backless mode, the cross-pass assembly 200 can be conveniently removed from the receiving slot 310 for use.

[0060] like Figures 1 to 5 As shown, the child vehicle may be equipped with a connection assembly 400 and an adjustment assembly 500. The connection assembly 400 may be, for example, a latch assembly, used to secure the child vehicle to the vehicle seat 10. See also Figure 3 and Figure 4 Connecting components 400 may be provided on both sides of the seat assembly 120. Each connecting component 400 may include a connector 410 and an adjusting strap 420. The adjusting strap 420 may be adjusted and threaded through the seat assembly 120 via the adjusting component 500. The connector 410 may be connected to one end of the adjusting strap 420 and may be used to connect to a connector (not shown) configured on the vehicle seat 10 to secure the seat assembly 120 to the vehicle seat 10. The connector 410 may be, for example, a hook, an ISOFIX connector, etc.

[0061] Mounting holes 430 may be provided on the rear side of the seat assembly 120, that is, on the side of the seat assembly 120 facing the backrest surface 11 of the vehicle seat 10. The number of mounting holes 430 may match the number of connectors 410 and may be adapted to accommodate the corresponding connectors 410. In this embodiment, there may be two mounting holes 430. The two mounting holes 430 may be provided near the left and right sides of the seat assembly 120, respectively. On the front side of the seat assembly 120, that is, on the side of the seat assembly 120 away from the backrest surface 11 of the vehicle seat 10, adjusting holes 440 may be provided. The adjusting holes 440 may communicate with each mounting hole 430. Each adjusting strap 420 may be passed through the adjusting hole 440 and the corresponding mounting hole 430, respectively. The end of each adjusting strap 420 near the backrest surface 11 of the vehicle seat 10 may be connected to the corresponding connector 410, and the other end (i.e., the adjusting end of the adjusting strap 420) may extend from the adjusting hole 440. By pulling the adjustment strap 420, the position of the connector 410 can be adjusted relative to the seat assembly 120. This allows for easy connection or disconnection of the connector 410 from the connector of the vehicle seat 10, as well as easy placement or removal of the connector 410 from the mounting hole 430.

[0062] See Figure 4 and Figure 5 The adjustment assembly 500 may include an adjustment member 510. The adjustment member 510 is movably disposed within and operable the adjustment hole 440; specifically, the adjustment member 510 is pivotally connected within the adjustment hole 440. The adjustment member 510 can switch between a locked position and an unlocked position. When the adjustment member 510 is in the locked position, the adjustment band 420 is restricted from moving relative to the seat assembly 120 in a predetermined direction. In this embodiment, the predetermined direction may include, for example, a rearward direction. That is, the adjustment band 420 can be pulled forward but not backward. When the adjustment member 510 is in the unlocked position, the adjustment band 420 is allowed to move relative to the seat assembly 120 in a predetermined direction; specifically, the adjustment band 420 can be pulled forward to move the connector 410 closer to the mounting hole 430, or the adjustment band 420 can be pulled backward to move the connector 410 away from the mounting hole 430. It should be noted that in some other embodiments, the predetermined direction may include, for example, forward, or may include both forward and backward directions, and this invention does not limit this.

[0063] See also Figure 4 and Figure 5The adjusting member 510 may include an operating portion 512 and a pivot portion 513 connected to each other. A clearance portion 514 and a plurality of first serrated portions 511 may be provided on the outer periphery of the pivot portion 513. The clearance portion 514 may be located on the side of the plurality of first serrated portions 511 away from the operating portion 512. A plurality of second serrated portions 462 may be provided within the adjusting hole 440. The plurality of second serrated portions 462 may be arranged generally in a front-rear direction. When the adjusting member 510 is in the locked position, at least a portion of the plurality of first serrated portions 511 may correspond to the second serrated portions 462, and the first serrated portions 511 and the second serrated portions 462 may respectively abut against both sides of the adjusting belt 420. This increases the frictional force of the plurality of first serrated portions 511 and the plurality of second serrated portions 462 on the adjusting belt 420, thereby limiting the movement of the adjusting belt 420 relative to the seat assembly 120 in a predetermined direction. In this embodiment, the plurality of first serrated portions 511 and the plurality of second serrated portions 462 are inclined forward, so that when the adjusting member 510 is in the locked position, the adjusting band 420 can be restricted from moving backward relative to the seat assembly 120, but can move forward relative to the seat assembly 120. When the adjusting member 510 is in the unlocked position, the plurality of first serrated portions 511 can be offset from the plurality of second serrated portions 462, and the clearance portion 514 can be aligned with the second serrated portions 462, so that the minimum gap between the adjusting member 510 and the second serrated portions 462 can be increased, thereby allowing the adjusting band 420 to move bidirectionally in the fore-and-aft direction relative to the seat assembly 120. In this embodiment, the clearance portion 514 can be generally planar.

[0064] The inner wall of the adjusting hole 440 may form a guide surface 461. The guide surface 461 may be generally planar. The guide surface 461 may extend generally in the front-rear direction and may be provided with a plurality of second serrated portions 462. The adjusting member 510 may be disposed above the guide surface 461 and may form a gap with the guide surface 461. The adjusting band 420 may be passed between the adjusting member 510 and the guide surface 461 and may be adapted to be laid flat on the guide surface 461. When the adjusting member 510 is in the unlocked position, the clearance portion 514 may be generally parallel to the guide surface 461, which can increase the minimum gap between the clearance portion 514 and the plurality of serrated portions 462 and reduce the friction of the clearance portion 514 and / or the second serrated portions 462 on the adjusting band 420.

[0065] Optionally, a third serrated portion 463 may also be provided within the adjusting hole 440. The third serrated portion 463 may be located at the front end of the plurality of second serrated portions 462. The inclination direction of the third serrated portion 463 may be opposite to the inclination direction of the plurality of second serrated portions 462, that is, the third serrated portion 463 may be inclined backward. The height of the third serrated portion 463 in the vertical direction may be greater than the height of at least a portion of the plurality of second serrated portions 462. Thus, when the adjusting member 510 is in the unlocked position, the third serrated portion 463 can lift the adjusting band 420, allowing the adjusting band 420 to separate from at least a portion of the plurality of serrated portions 462, thereby enabling the adjusting band 420 to move backward more smoothly.

[0066] The operating principles of the connecting component 400 and the adjusting component 500 provided in this embodiment of the present invention are as follows.

[0067] When connector 410 is not needed, the adjusting band 420 can be pulled forward without operating the adjusting band 510, causing connector 410 to move forward and be received within the mounting hole 430. When it is necessary to connect seat assembly 120 to vehicle seat 10, the adjusting band 510 can be operated to switch it to the unlocked position; then connector 410 can be removed from mounting hole 430 and connected to connector (not shown) of vehicle seat 10, thereby fixing seat assembly 120 to vehicle seat 10.

[0068] This embodiment of the invention also provides a buffer structure 113 and a child vehicle equipped with the buffer structure 113. The child vehicle may be, for example, a child safety seat. It should be understood that the buffer structure 113 provided in this embodiment can be applied to the child vehicle provided in the above embodiments.

[0069] Figure 8 A structural schematic diagram of a child carrier according to another embodiment of the present invention is shown. Figure 8 and Figure 9 As shown, in some embodiments, the child vehicle may include a seat body 100. The seat body 100 may include a backrest assembly 110 and a seat assembly 120. The backrest assembly 110 and the seat assembly 120 may be detachably connected or non-detachably connected.

[0070] The backrest assembly 110 may include a backrest body 111 and two side wings 112 disposed on the left and right sides of the backrest body 111. Exemplarily, the backrest body 111 may be generally flat. Figure 6As shown, when the backrest assembly 110 is installed on the vehicle seat 10, the backrest body 111 can abut against the backrest surface 11 of the vehicle seat 10. The two side wings 112 can reduce the lateral swaying of the child's body during vehicle cornering and can protect the child's left and right sides during sudden braking or a collision. In this embodiment, at least a portion of the backrest body 111 can be integrally formed with the two side wings 112.

[0071] See also Figure 8 and Figure 9 Each side wing portion 112 may include a side wing main body 1122 and a front wall 1121. Each side wing main body 1122 may be connected to the backrest main body 111. Each side wing main body 1122 and the backrest main body 111 may be arranged at an angle. The angle between the side wing main body 1122 and the backrest main body 111 may be an obtuse angle slightly greater than 90°. The two side wing main bodies 1122 may be arranged opposite each other and may each have an inner surface facing each other and an outer surface facing away from each other. The front wall 1121 may be provided on the side of the side wing main body 1122 away from the backrest main body 111, that is, on the front side of the side wing main body 1122. A recess 1123 is formed between the front wall 1121 and the side wing main body 1122. Each side wing portion 112 may be provided with a buffer structure 113. The cushioning structure 113 can be used to cushion the lateral (e.g., left or right) impact forces that the backrest assembly 110 may be subjected to.

[0072] For ease of description, the following explanation will take the buffer structure 113 located on one side of the backrest assembly 110 as an example.

[0073] See Figures 7 to 10 In some embodiments, the buffer structure 113 may include a buffer housing 1131. The buffer housing 1131 may be connected to the side wing main body 1122. The buffer housing 1131 and the side wing main body 1122 may together form a buffer cavity 1134. The buffer cavity 1134 may extend from the front wall 1121 toward the backrest main body 111. The buffer cavity 1134 may have an opening, which may generally face forward. In this embodiment, the buffer housing 1131 may be disposed in the recess 1123 of the side wing 112 and may also be connected to the front wall 1121. The outer surface of the buffer housing 1131 may be at least partially flush with the outer edge of the front wall 1121 in the left-right direction. Thus, when subjected to lateral impact force, the buffer housing 1131 and the buffer cavity 1134 can buffer the lateral impact force. In other embodiments, the front wall 1121 may not be provided, and this is not a limitation of the present invention.

[0074] The buffer housing 1131 may include a first wall portion 11311 and second wall portions 11312 generally parallel to each other on opposite sides of the first wall portion 11311. Each of the second wall portions 11312 may be generally flat and may be connected to the side wing body portion 1122 and the front wall 1121 respectively. The first wall portion 11311 may be generally arcuate and may be disposed opposite to the side wing body portion 1122. That is, the first wall portion 11311 may be connected to the side of the second wall portion 11312 away from the side wing body portion 1122. Optionally, the buffer housing 1131 may further include a third wall portion 11313. The third wall portion 11313 may be connected between the side wing body portion 1122 and the first wall portion 11311. In this embodiment, the buffer cavity 1134 may have a bottom wall opposite to its opening. The third wall portion 11313 may form the bottom wall of the buffer cavity 1134.

[0075] The buffer structure 113 may further include a buffer portion 1132 disposed within the buffer cavity 1134. The buffer portion 1132 may be disposed laterally within the buffer cavity 1134. Both ends of the buffer portion 1132 may be connected to the side wing main body portion 1122 and the first wall portion 11311, respectively. Specifically, the buffer portion 1132 may have a first connecting end 11321 connected to the first wall portion 11311 and a second connecting end 11322 connected to the side wing main body portion 1122. The line connecting the first connecting end 11321 and the second connecting end 11322 may be parallel to the second wall portion 11312. Multiple buffer portions 1132 may be disposed between two second wall portions 11312. The buffer portion 1132 may extend along the depth direction of the buffer cavity 1134 (i.e., from the opening of the buffer cavity 1134 to the bottom wall of the buffer cavity 1134) to the opening and bottom wall of the buffer cavity 1134, respectively. The depth direction of the buffer cavity 1134 can be roughly parallel to the front-back direction.

[0076] See Figure 8In some embodiments, the buffer portion 1132 may be a reinforcing rib 1132a arranged laterally within the buffer cavity 1134. This reinforcing rib 1132a may, for example, be wavy. The wavy reinforcing rib 1132a enhances the impact resistance of the buffer housing 1131 and also readily undergoes elastic deformation in the lateral direction, effectively absorbing the lateral impact force received by the buffer structure 113 and further improving the impact resistance of the buffer structure 113. The number of wavy reinforcing ribs 1132a may be multiple, such as two, three, four, etc., but is not limited thereto. Each wavy reinforcing rib 1132a may include at least one trough and at least one crest. Optionally, the troughs of multiple wavy reinforcing ribs 1132a may correspond to each other, and the crests of multiple wavy reinforcing ribs 1132a may correspond to each other. Here, the term "corresponding" means that the troughs or crests of multiple wavy reinforcing ribs 1132a may be approximately located on the same plane or a straight line. Of course, in some other embodiments, the number and wave shape of the wave-shaped reinforcing ribs 1132a to be set can be selected according to the actual anti-collision performance requirements.

[0077] In this embodiment, the buffer portion 1132 provided within the buffer cavity 1134 serves two purposes: firstly, it acts as a reinforcing rib, enhancing the overall impact resistance of the buffer structure 113; secondly, it can partially absorb and buffer external impact forces (especially lateral external impact forces) through elastic deformation, thereby further enhancing the impact resistance of the buffer structure 113. Thus, the side wing portion 112 is less prone to shattering upon external impact or collision, thereby better protecting children riding in child vehicles.

[0078] In other embodiments, the buffer portion 1132 may be a reinforcing rib of other shapes, such as a straight reinforcing rib. Straight reinforcing ribs are easier to process and have lower production costs. The buffer portion 1132 may also include components for cushioning, such as springs or foam, or may include at least a combination of two of the above-mentioned wavy ribs, straight ribs, springs, or foam.

[0079] See Figure 8 and Figure 9In one embodiment, the buffer structure 113 may further include connecting ribs 1133. These connecting ribs 1133 can be connected to the side wing main body 1122 and the buffer shell 1131, respectively. Specifically, the connecting ribs 1133 can be connected to the third wall portion 11313 and the side wing main body 1122, and can extend towards the backrest main body 111. The number of connecting ribs 1133 can be multiple, for example, three. The multiple connecting ribs 1133 can be substantially parallel to each other and can be arranged horizontally. Specifically, the multiple connecting ribs 1133 can be distributed approximately at equal intervals along the vertical direction. The reinforcing ribs located at the uppermost and lowermost ends can be approximately coplanar with the corresponding second wall portions 11312 located at the uppermost and lowermost ends, for example, they can be considered as being formed by two second wall portions 11312 extending towards the backrest main body 111, respectively. The connecting ribs 1133 can further enhance the strength of the buffer structure 113 and improve its buffering performance against external impact forces.

[0080] The inner surface of the side wing main body 1122 can be a smooth surface, and the outer surface of the side wing main body 1122 can form the inner wall of the buffer cavity 1134. Compared with the traditional child vehicle that has a concave-convex structure on the inner surface of the side wing main body, the smooth inner surface of the side wing 112 according to the embodiment of the present invention can improve the comfort of children riding.

[0081] The buffer structure 113 provided in this embodiment can effectively buffer the external impact force that the side wing 112 may bear, especially the lateral impact force, and reduce the possibility of the backrest assembly 110 breaking under the action of external impact force, thereby better protecting the child riding in the child vehicle.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
