Description

[Technical Field]

[0001] This invention relates to the field of children's products technology, and in particular to a children's vehicle that can be used in multiple scenarios. [Background Technology]

[0002] Strollers play a vital role in daily life for users taking infants and toddlers out and about, and have become an indispensable children's product in a child's growth process. In existing technology, strollers have diverse structures, varying connections between components, and differ in load-bearing stability, seat installation methods, frame folding methods and principles, resulting in varying folded shapes and sizes. How to make strollers, while maintaining good load-bearing capacity, have simpler component structures, easier folding operations, and a smaller folded size, has always been a goal pursued by researchers in this field.

[0003] On the other hand, child car seats are typically only installed in cars for children to use while riding, resulting in low utilization. While some existing strollers have frames that can be fixedly fitted with child car seats, this usually involves a detachable car seat bracket on the stroller frame or a matching detachable connection structure between the stroller frame and the child car seat. This complicates the stroller's structure, makes the folded stroller frame less flat, affecting storage and portability, and requires additional adjustments to the car seat structure, thus lacking versatility.

[0004] Therefore, this invention addresses the aforementioned problems. [Summary of the Invention]

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a child carrier that can be used in multiple scenarios. By simply operating the support component to switch between the unfolded and folded states, the child carrier can switch between the stroller and car seat states respectively, thus enabling the child carrier to meet the usage needs of different scenarios and featuring quick switching, multi-functionality, and strong applicability.

[0006] This invention is achieved through the following technical solution:

[0007] A child vehicle that can be used in multiple scenarios includes:

Detailed Implementation Methods

[0072] The following is in conjunction with the appendix Figure 1-31 The embodiments of the present invention will be described in detail.

[0073] like Figure 1 , 2 As shown in Figures 17 and 22-26, a child carrier that can be used in multiple scenarios includes a carrier body 1, a support component 2, and a connecting connector 30. The support component 2 is connected to the carrier body 1 and has an unfolded state and a folded state. During the switching between the unfolded and folded states, the support component 2 enables the child carrier to switch between a stroller usage state and a car seat usage state accordingly. In the stroller usage state, the child carrier is used as an infant stroller. In the car seat usage state, the child carrier is used to connect with a car seat. The connecting connector 30 is configured to cooperate with an ISOFIX connector on a car seat when the child carrier is in the car seat usage state. This invention allows the child carrier to switch between stroller and car seat modes simply by operating the support component to extend or retract. This enables the child carrier to meet the needs of different usage scenarios, featuring quick switching, convenient operation, multi-functionality, and strong applicability. Furthermore, when driving, users do not need to carry a dedicated stroller frame, effectively reducing the number and weight of child-related items and facilitating travel. When used with a car seat, it connects to the car seat without requiring an additional separate base, making it convenient to use.

[0074] In this invention, the car seat usage state refers to the car seat usage state.

[0075] like Figures 29-31 As shown, the connecting connector 30 is an ISOFIX connector or a resilient snap fastener, and the connecting connector 30 is connected to the vehicle body 1 or the support assembly 2 via a connecting strap. This embodiment is adapted to US standard usage. Specifically, when the connecting connector 30 is an ISOFIX connector, the ISOFIX connector on the car seat is an ISOFIX socket that mates with the ISOFIX connector; when the connecting connector 30 is a resilient snap fastener, the ISOFIX connector on the car seat is an ISOFIX anchor point, and the resilient snap fastener can automatically and elastically close to connect with the ISOFIX anchor point of the car seat.

[0076] like Figure 7-9 The diagram also includes an ISOFIX component 3, which is mounted on the support component 2 or the vehicle body 1. The connector 30 is an ISOFIX connector and is mounted on the ISOFIX component 3. This embodiment is adapted to European standards. In this embodiment, the ISOFIX connector on the car seat is an ISOFIX socket that mates with the ISOFIX connector.

[0077] like Figure 7-9As shown, the ISOFIX assembly 3 is mounted on the support assembly 2 and, in the car seat usage state, is located below or outside the support assembly 2. When the child carrier is in stroller usage state, the support assembly 2 causes the ISOFIX assembly 3 to unfold relative to the carrier body 1 while the ISOFIX assembly 3 remains folded and connected to the support assembly 2. When the child carrier is in car seat usage state, the ISOFIX assembly 3 can be folded or unfolded relative to the support assembly 2, allowing the connecting joint 30 to engage with the ISOFIX connectors on the car seat. Figure 24 , 25 As shown, when the car seat is in use, the support components are in a retracted state relative to the vehicle body, meaning the front and rear foot components are respectively close to the sides of the vehicle body. This improves the utilization of interior space and enhances passenger safety. Figure 1-3 As shown, when the stroller is in use, the front and rear leg components unfold and support the ground, making it easy to push, and the process of switching between child vehicles is convenient and easy to operate.

[0078] The specific structures of the ISOFIX component 3 and the connector 30 can be found in: Chinese Patent Application No. CN201910001404.5, which is an ISOFIX connector and a car seat, and Chinese Patent Application No. CN202120139175.6, which is an ISOFIX connector and a car seat, etc.

[0079] like Figure 1-9 As shown in Figures 17-20, for easy folding and unfolding, the carrier body 1 has a seat 11 and a backrest assembly 12. The backrest assembly 12 is rotatably connected to the seat 11. A backrest locking mechanism 13 is provided between the backrest assembly 12 and the seat 11 to lock the backrest assembly 12 relative to the seat 11 when the backrest assembly 12 is flipped backward relative to the seat 11 to a preset angle.

[0080] like Figure 7-9 As shown, the child carrier also has a folded storage state. In this state, the front surface of the backrest assembly 12 faces the upper surface of the seat 11 at an acute angle or parallel to it, and the support assembly 2 is also folded down. This minimizes the volume of the child carrier in the folded storage state, making it easier to transport and store. In this embodiment, in the folded storage state, the backrest assembly 12 is locked relative to the seat 11 by a backrest folding locking assembly. The backrest folding locking assembly can be a hook provided on the seat 11 for hooking onto the backrest assembly 12.

[0081] like Figure 26 , 27As shown, the child carrier also has a towing mode. In this mode, the front surface of the backrest assembly 12 faces the upper surface of the seat 11 at an acute angle or parallel to it, and the support assembly 2 is in a folded state for easy towing. Figure 26 As shown, when the child vehicle is in a towed state, the front surface of the backrest assembly 12 is in contact with the upper surface of the seat 11, the support assembly 2 is in a retracted state, and the handle assembly 4 extends relative to the backrest assembly 12. Figure 27 As shown, when the child vehicle is in a towing state, the backrest assembly 12 is flipped open relative to the seat 11, the support assembly 2 is in a folded state, and the handle assembly 4 extends relative to the backrest assembly 12.

[0082] like Figure 10-12 As shown in Figures 17 and 18, in order to better lock the backrest assembly relative to the seat, the backrest locking mechanism 13 includes a backrest locking hole 131 provided on the backrest assembly 12 and a backrest locking block 132 slidably provided on the seat 11 and capable of being inserted into the backrest locking hole 131 when the backrest assembly 12 is flipped back relative to the seat 11 to a preset angle. A locking slider elastic member 133 is provided between the backrest locking block 132 and the seat 11 to allow the backrest locking block 132 to be elastically inserted into the backrest locking hole 131.

[0083] like Figure 10-12 As shown, to facilitate unlocking, a handle assembly 4 is also included. The handle assembly 4 is slidably mounted on the backrest assembly 12. The backrest locking mechanism 13 is configured to release when the handle assembly 4 slides relative to the backrest assembly 12 to a preset position. In this embodiment, when the handle assembly 4 slides downward relative to the backrest assembly 12, the lower end of the handle assembly 4 presses against the backrest locking block 132, causing the locking end of the backrest locking block 132 to disengage from the backrest locking hole 131. Figure 12 As shown, this releases the locking state of the backrest assembly relative to the seat, allowing the backrest assembly to be flipped and folded towards the seat.

[0084] like Figure 15 , 17As shown in Figure 18, in order to achieve linkage unlocking for easy unlocking operation, a usage state locking mechanism 5 is also included. The usage state locking mechanism 5 is configured to lock the child carrier in either stroller usage state or car seat usage state, and is configured to be released by the backrest assembly 12 when it is flipped forward relative to the seat 11 to a preset angle. In this embodiment, during the process of the backrest assembly flipping towards the seat, the backrest assembly 12 releases the stroller state locking mechanism 51 of the usage state locking mechanism 5 in linkage with the backrest assembly 12. Therefore, the stroller state locking mechanism 51 can be released without the user having to operate the unlocking mechanism separately, so that the unfolded front leg assembly 21 and rear leg assembly 22 can be folded up, allowing the child carrier to quickly switch from stroller usage state to car seat usage state.

[0085] like Figure 1 , 2 As shown in Figures 17-20, the backrest assembly 12 includes a backrest 121 rotatably connected to the seat 11 and a side connecting portion 122 connected to the seat 11. A backrest adjustment mechanism 123 is provided between the backrest 121 and the side connecting portion 122 to adjust the tilt angle of the backrest 121 relative to the side connecting portion 122. This allows the backrest 121 to be adjusted to different angles relative to the side connecting portion 122, i.e., adjusting the opening angle between the backrest 121 and the seat 11, providing users with various usage postures and improving the user experience. In this embodiment, the opening angle between the backrest assembly 12 and the seat 11 is 0-98°, and the opening angle between the backrest 121 and the seat 11 is 0-158°.

[0086] like Figure 10-12 As shown, in this embodiment, the backrest locking mechanism 13 is located between the side connecting part 122 and the seat part 11.

[0087] like Figure 24 As shown, the backrest assembly 12 has an upper pull strap 1221 connected to its side wall. By pulling the upper pull strap 1221, the user can easily operate the backrest assembly to flip and unfold or fold relative to the seat.

[0088] like Figure 13 , 19As shown in Figure 20, the backrest adjustment mechanism 123 includes a plurality of backrest adjustment holes 1231 located on the side of the side connection portion 122 near the backrest 121, and a backrest adjustment pin 1232 slidably disposed on the backrest 121 and capable of being inserted into the corresponding backrest adjustment hole 1231. An adjustment pin elastic element 1233 is provided between the backrest adjustment pin 1232 and the backrest 121 to allow the backrest adjustment pin 1232 to elastically insert into the backrest adjustment hole 1231. The backrest adjustment mechanism 123 also includes an adjustment unlocking element 1234 movably disposed on the backrest 121 for triggering the unlocking action of the backrest adjustment pin 1232. In this embodiment, the adjustment unlocking element 1234 is connected to the backrest adjustment pin 1232 via a linkage pull rope, and the backrest 121 is provided with a backrest groove / passage for the linkage pull rope to pass through, such as... Figure 13 As shown. When it is necessary to adjust the tilt angle of the backrest 121, the user slides the adjustment unlocking piece 1234 upward relative to the backrest 121. The linkage pull rope then drives the backrest adjustment pin 1232 to slide laterally relative to the backrest 121, causing the backrest adjustment pin 1232 to disengage from the backrest adjustment hole 1231. When the backrest 121 is flipped to the desired angle, the adjustment unlocking piece 1234 is released, and the adjustment pin elastic piece 1233 causes the backrest adjustment pin 1232 to slide back to its original position and insert into the corresponding backrest adjustment hole 1231, thus keeping the backrest 121 at the desired angle.

[0089] like Figure 2 , 17 As shown in Figures 19 and 20, a headrest 6 is provided on the front side of the backrest 121, which can be adjusted up and down relative to the backrest 121. A headrest adjustment locking mechanism 61 is provided between the headrest 6 and the backrest 121. The headrest adjustment locking mechanism 61 includes headrest adjustment locking holes 611 that are spaced up and down on the backrest 121 and headrest adjustment locking pins 612 that are slidably provided on the headrest 6 and can be inserted into the corresponding headrest adjustment locking holes 611. A headrest adjustment elastic member is provided between the headrest adjustment locking pin 612 and the headrest 6, which allows the headrest adjustment locking pin 612 to be elastically inserted into the headrest adjustment locking hole 611. For easy unlocking, the headrest 6 is provided with a headrest handle for unlocking the headrest adjustment lock pin 612. By pulling the headrest handle, the headrest adjustment lock pin 612 is disengaged from the headrest adjustment lock hole 611. When the headrest 6 is adjusted to the desired position, the headrest handle is released, and the headrest adjustment elastic element causes the headrest adjustment lock pin 612 to insert into the corresponding headrest adjustment lock hole 611 to lock the headrest 6.

[0090] In this embodiment, a headrest sliding groove is provided on the front side of the backrest 121 to limit the up and down movement direction of the headrest 6 and guide the movement of the headrest 6, so that the headrest 6 can slide stably and smoothly along the set direction.

[0091] like Figure 17 ,20 As shown in Figure 21, the device also includes a handle assembly 4, which is slidably mounted on the side connecting portion 122. A handle adjustment locking mechanism 41 is provided between the handle assembly 4 and the side connecting portion 122. The side connecting portion 122 has a sliding slot for the handle assembly 4 to slide within it. In this embodiment, the handle adjustment locking mechanism 41 includes a plurality of handle adjustment locking holes 411 spaced vertically on the side connecting portion 122 and handle adjustment locking blocks 412 slidably mounted on the handle assembly 4 and capable of being inserted into the corresponding handle adjustment locking holes 411. An adjustment locking block elastic member is provided between the handle adjustment locking block 412 and the handle assembly 4 to allow the handle adjustment locking block 412 to elastically insert into the handle adjustment locking hole 411. The handle assembly 4 also has a handle adjustment unlocking button 413 for linking the unlocking action of the handle adjustment locking block 412. When adjusting and unlocking, the user presses the handle adjustment unlock button 413 to cause the handle adjustment locking block 412 to slide relative to the handle assembly 4, so that the locking end of the handle adjustment locking block 412 disengages from the handle adjustment locking hole 411. At this time, the handle assembly 4 can be operated to slide the opposite side connecting part 122 upward or downward. When the desired position is reached, the handle adjustment unlock button 413 is released, and the locking block elastic element is adjusted so that the locking end of the adjustment locking block 412 is inserted into the corresponding handle adjustment locking hole 411.

[0092] like Figure 14 , 16 As shown in Figures 19 and 21, the handle assembly 4 is provided with a backrest blocking assembly 42 that prevents the backrest 121 from flipping backward relative to the side connecting part 122. A handle anti-foolproof locking mechanism 43 is provided between the handle assembly 4 and the side connecting part 122 to lock the handle assembly 4 relative to the side connecting part 122 when the backrest blocking assembly 42 releases its obstruction of the backrest 121. The handle anti-foolproof locking mechanism 43 is configured to be released by the backrest 121 when the backrest 121 flips forward to a preset position relative to the side connecting part 122. In this embodiment, when the handle assembly 4 is not pulled out to allow the backrest blocking assembly 42 to engage with the backrest 121, the backrest 121 cannot flip backward relative to the side connecting part 122, and the backrest assembly 12 and the seat 11 can only achieve an opening angle of 0-98°. Figure 1 , 2 As shown; when the backrest blocking component 42 of the handle assembly 4 is pulled out to remove its obstruction of the backrest 121, the backrest 121 of the backrest assembly 12 can flip backward relative to the side connecting part 122, that is, the backrest 121 of the backrest assembly 12 and the seat part 11 can achieve an opening and closing angle of 0-158°, as shown. Figure 28 As shown.

[0093] In this embodiment, the backrest blocking component 42 is used in conjunction with the handle anti-fooling locking mechanism 43 to achieve interlocking between the handle component 4 and the backrest 121, ensuring reliable use.

[0094] like Figure 16 , 19 As shown, the handle anti-fooling locking mechanism 43 includes a handle anti-fooling locking hole 431 provided on the handle assembly 4 and a handle anti-fooling locking pin 432 slidably provided on the side connecting part 122 and capable of being inserted into the handle anti-fooling locking hole 431. A handle anti-fooling elastic member 433 is provided between the handle anti-fooling locking pin 432 and the side connecting part 122 to allow the handle anti-fooling locking pin 432 to elastically insert into the handle anti-fooling locking hole 431. The handle anti-fooling locking pin 432 is configured to be released by the backrest 121 when the backrest 121 is flipped forward relative to the side connecting part 122 to a preset position. When adjusting the backrest 121 so that the opposite side connecting part 122 is flipped backward, the opposite side connecting part 122 of the handle assembly 4 must first be slid upward to remove the backrest blocking assembly 42 from blocking the backrest 121. At the same time, the handle anti-fooling pin 432 is inserted into the handle anti-fooling locking hole 431 to lock the handle assembly 4. Figure 1 , 2 As shown, at this moment, the user can operate the backrest 121 to flip the opposite side connecting part 122 backward (it can flip within 98°-158°), as... Figure 28 As shown; when it is necessary to operate the handle assembly 4 to retract the side connecting part 122, it is necessary to first operate the backrest 121 to flip the opposite side connecting part 122 forward to the preset position. The backrest 121 then works in conjunction with the handle anti-fooling lock pin 432 to unlock, thereby releasing the handle anti-fooling locking mechanism 43 from locking the handle assembly 4.

[0095] like Figure 1 , 2As shown in Figure 17, in order to better fold or unfold the support assembly and improve switching efficiency, the support assembly 2 includes a front leg assembly 21 and a rear leg assembly 22. The middle part of the front leg assembly 21 is rotatably connected to the carrier body 1, and the upper end of the front leg assembly 21 is rotatably connected to the upper end of the rear leg assembly 22. The middle part of the rear leg assembly 22 is rotatably and slidably connected to the carrier body 1 through a joint assembly 23. The ISOFIX assembly 3 is disposed on the front leg assembly 21. When the child carrier is in the car seat usage state, both the front leg assembly 21 and the rear leg assembly 22 are close to the carrier body 1. When the child carrier is in the stroller usage state, the front leg assembly 21 and the rear leg assembly 22 are configured to connect the wheel set and support the ground. The joint assembly 23 includes a joint seat 231 rotatably disposed on the carrier body 1. The joint seat 231 is provided with a guide slot 232 for the rear leg assembly 22 to slide within it. In this embodiment, the rear leg assembly 22 is connected by a joint assembly and a guide slot 232. While rotating, the rear leg assembly 22 slides relative to the joint seat 231, which allows the rear leg assembly and the front leg assembly to quickly and efficiently fold into the car seat or unfold into the trolley use state. When in the car seat use state, the front leg assembly and the rear leg assembly are respectively close to the seat side. Since this folding and unfolding can be achieved without adding any other connecting rods, the folding volume and overall weight are minimized.

[0096] like Figure 1-4 As shown, a flexible connector 24 is provided between the front leg assembly 21 and the rear leg assembly 22. The flexible connector 24 is stretched and tightened when the trolley is in use, thus limiting the distance between the front leg assembly 21 and the rear leg assembly 22. When the trolley is in use, the flexible connector pulls the front leg assembly and the rear leg assembly to open at a stable angle, thus creating a stable triangular opening structure.

[0097] like Figure 1 , 2 As shown, in order to further improve the structural strength and stability of the child vehicle, a reinforcing crossbar 25 is provided between the two front foot assemblies 21 and between the two rear foot assemblies 22.

[0098] like Figure 1-12As shown, the reinforcing crossbar 25 or the bottom of the vehicle body 1 is provided with a clearance structure 26 for mutual avoidance when the car seat is in use. This allows the front and rear leg components of the child vehicle to be closer to the vehicle body when it is folded up, reducing the overall size of the child vehicle and making it easier to store. In this embodiment, the clearance structure 26 includes a receiving groove on the bottom of the seat 11 for accommodating the reinforcing crossbar 25. When the car seat is in use, the reinforcing crossbar 25 is folded into the receiving groove. At this time, the reinforcing crossbar 25 can be used as a reinforcing structure for the vehicle body, improving the structural strength and stability of the vehicle body. Furthermore, the reinforcing crossbar 25 located between the two rear leg components 22 or the two front leg components 21 adopts a U-shaped structure. This U-shaped structure cooperates with a receiving groove. The receiving groove does not need to be designed too deep to avoid affecting the structural strength or design of the vehicle body.

[0099] like Figure 22-25 As shown, the front part of the ISOFIX assembly 3 is rotatably connected to the lower part of the front foot assembly 21. A support rod 31 is provided between the ISOFIX assembly 3 and the front foot assembly 21. The lower end of the support rod 31 is rotatably connected to the rear part of the ISOFIX assembly 3, and the upper end of the support rod 31 is rotatably and slidably connected to the front foot assembly 21. A support locking mechanism 32 is provided between the upper end of the support rod 31 and the front foot assembly 21. When the car seat is in use, by operating the upper end of the support rod 31 to connect with the front foot assembly 21, the ISOFIX assembly 3 can be adjusted to fold or unfold relative to the support assembly 2 to meet different riding needs or usage scenarios.

[0100] like Figure 23 , 25 As shown, the front foot assembly 21 is provided with a front foot groove 211 extending along the length direction of the front foot assembly 21, and the upper end of the support rod 31 is rotatably placed in the front foot groove 211. In this embodiment, the front foot groove 211 can limit and guide the upper end of the support rod 31, ensuring that the upper end of the support rod 31 can only slide in a set direction.

[0101] like Figure 22-25 As shown, the support locking mechanism 32 is configured to lock the upper end of the support rod relative to the front foot assembly 21 when the ISOFIX assembly 3 is folded or unfolded relative to the support assembly 2. The support locking mechanism 32 includes two support locking protrusions 321 spaced apart on the front foot slide groove 211 and respectively communicating with both ends of the front foot slide groove 211, and a support locking sleeve 322 slidably disposed on the upper end of the support rod 31 and capable of being fitted onto the corresponding support locking protrusion 321 when the ISOFIX assembly 3 is folded or unfolded relative to the support assembly 2. The support rod 31 is provided with a locking sleeve unlocking member 323 for triggering the unlocking action of the support locking sleeve 322.

[0102] like Figure 17 , 18 As shown, the usage state locking mechanism 5 includes a stroller state locking mechanism 51 for locking the child carrier in the stroller usage state and a car seat state locking mechanism 52 for locking the child carrier in the car seat usage state. The support assembly 2 includes a front leg assembly 21 and a rear leg assembly 22. The middle part of the front leg assembly 21 is rotatably connected to the carrier body 1, and the upper end of the front leg assembly 21 is rotatably connected to the upper end of the rear leg assembly 22. The middle part of the rear leg assembly 22 is rotatably and slidably connected to the carrier body 1 through a joint assembly 23. The stroller state locking mechanism 51 is located between the rear leg assembly 22 and the carrier body 1, and the car seat state locking mechanism 52 is located between the front leg assembly 21 and the carrier body 1. In this embodiment, the stroller state locking mechanism 51 and the car seat state locking mechanism 52 are independently arranged, which can better lock the child carrier in the corresponding usage state, ensuring safety and reliability.

[0103] like Figure 15 , 17 As shown in Figure 18, to better lock the child vehicle, the stroller locking mechanism 51 includes a stroller locking hole 511 on the rear leg assembly 22 and a stroller locking pin 512 movably disposed on the vehicle body 1 and capable of being inserted into the stroller locking hole 511 when the child vehicle is in use. A locking pin elastic element is provided between the stroller locking pin 512 and the vehicle body 1 to allow the stroller locking pin 512 to elastically insert into the stroller locking hole 511. In this embodiment, when the stroller is in use, the locking end of the stroller locking pin 512 simultaneously passes through the joint locking hole 2311 of the joint seat 231 and the stroller locking hole 511, thereby restricting the rotation of the joint seat 231 relative to the vehicle body 1 while also restricting the sliding of the rear leg assembly 22 relative to the joint seat 231 or the vehicle body 1.

[0104] like Figure 14 , 17 As shown in Figure 18, in order to better lock the child vehicle, the car seat locking mechanism 52 includes a car seat locking groove 521 provided on the vehicle body 1 and a car seat locking crossbar 522 provided on the front foot assembly 21, which can be inserted into the car seat locking groove 521 when the child vehicle is in use. The vehicle body 1 is slidably provided with a car seat locking slider 523 for locking the car seat locking crossbar 522 in the car seat locking groove 521. A locking slider elastic element is provided between the car seat locking slider 523 and the vehicle body 1.
