A children's vehicle capable of switching between multiple scenes

Technical field

[0001] This application relates to the technical field of children's products. This application is based on the application with Chinese application number CN202323284378.2 and application date December 1, 2023, and claims its priority. The disclosed content of the Chinese application is hereby introduced into this application as a whole. [Background Technology]

[0002] Strollers play a vital role in daily life, allowing users to carry infants and young children. They have become an indispensable childcare product for children's growth. Prior art strollers have diverse structures, differing in the connection relationships between various levers, load-bearing stability, seat installation methods, frame folding methods and principles, and folded shapes and volumes. How to improve strollers while maintaining good load-bearing performance while simplifying the lever structure, making folding easier, and reducing the size of the folded stroller has long been a persistent goal for those in this field.

[0003] On the other hand, child car seats are usually only installed in cars for use when children are riding in the car, and their utilization rate is low. In the prior art, there are also some child strollers that can be fixed with child car seats on the stroller frame, but these usually require a detachable car seat bracket to be provided on the stroller frame, or a matching detachable connection structure to achieve the connection between the stroller frame and the child car seat. This complicates the structure of the stroller, resulting in the stroller frame being uneven when folded, which affects storage and carrying. At the same time, the car seat structure also needs to be adjusted accordingly, making it not universal.

[0004] Therefore, this application is studied and proposed in response to the above problems.

[0068] The following describes the implementation of the present application in detail with reference to Figures 1-31.

[0069] As shown in Figures 1, 2, 17, and 22-26, the present application provides a child carrier that can be used in multiple scenarios, including a carrier body 1, a support assembly 2, and a connecting joint 30. The support assembly 2 is connected to the carrier body 1 and has an expanded state and a folded state. The support assembly 2 switches between the expanded state and the folded state to enable the child carrier to switch between a stroller use state and a car seat use state respectively. In the stroller use state, the child carrier is used as an infant stroller, and in the car seat use state, the child carrier is used to be connected to a car seat; the connecting joint 30 is configured to cooperate with the ISOFIX connector on the car seat when the child carrier is in the car seat use state. The present application only requires operating the support assembly to switch between the expanded state and the folded state so that the child carrier can be switched between the stroller use state and the car seat use state respectively, so that the child carrier can meet the use requirements of different usage scenarios, and has the characteristics of quick switching, convenient operation, multi-function and strong applicability; at the same time, when the user drives out, there is no need to equip an additional dedicated stroller frame, which can effectively reduce the number and weight of children's equipment carried, making travel more convenient. When used with a car seat, it can be connected to the car seat without an additional independent base, which is easy to use.

[0070] The car seat usage state in this application refers to the usage state of the child carrier of this application connected to the car seat.

[0071] As shown in Figures 29-31, the connection connector 30 is an ISOFIX connector or an elastic buckle, and is connected to the vehicle body 1 or support assembly 2 via a flexible connecting strap. This embodiment is adapted for US standard usage. When the connection 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 connection connector 30 is an elastic buckle, the ISOFIX connector on the car seat is an ISOFIX anchor point, and the elastic buckle automatically closes and connects to the ISOFIX anchor point on the car seat.

[0072] As shown in Figures 7-9, this application also includes an ISOFIX assembly 3, which is mounted on the support assembly 2 or the vehicle body 1. The connection connector 30 is an ISOFIX connector and is mounted on the ISOFIX assembly 3. This embodiment conforms to European regulations. The ISOFIX connector on the car seat in this embodiment is an ISOFIX socket that mates with the ISOFIX connector.

[0073] As shown in Figures 7-9, the ISOFIX assembly 3 is mounted on the support assembly 2. When the child carrier is in use as a stroller, the ISOFIX assembly 3 is located below or outside the support assembly 2. When the child carrier is in use as a stroller, the support assembly 2 drives 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 use as a stroller, the ISOFIX assembly 3 can be folded or unfolded relative to the support assembly 2, allowing the connection connector 30 to cooperate with the ISOFIX connector on the car seat. As shown in Figures 24 and 25, when the child carrier is in use as a stroller, the support assembly is in a folded state relative to the carrier body, i.e., the front and rear leg assemblies are respectively abutted against the side of the carrier body, which can improve space utilization in the vehicle and enhance passenger safety. As shown in Figures 1-3, when the child carrier is in use as a stroller, the front and rear leg assemblies are unfolded and supported on the ground, making it easier to push the child carrier and making the switching process of the child carrier convenient and easy to operate.

[0074] Among them, the specific structure of the ISOFIX component 3 and the connecting joint 30 can be found in: Chinese patent application number CN201910001404.5 for ISOFIX connection component and safety seat, Chinese patent application number CN202120139175.6 for ISOFIX connection component and safety seat, etc.

[0075] As shown in Figures 1-9 and 17-20, in order to facilitate 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 for locking the backrest assembly 12 relative to the seat 11 when the backrest assembly 12 is flipped backward to a preset angle relative to the seat 11.

[0076] As shown in Figures 7-9, the child carrier also has a folded storage state. In this folded storage state, the front surface of the backrest assembly 12 is aligned with the upper surface of the seat 11 at an acute angle or parallel to each other, and the support assembly 2 is folded. 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 and the seat are locked relative to the seat 11 by a backrest folding locking assembly. The backrest folding locking assembly can be a retracting hook provided on the seat 11 for hooking onto the backrest assembly 12.

[0077] As shown in Figures 26 and 27, the child carrier also has a dragging mode. In this mode, the front surface of the backrest assembly 12 is opposite to the upper surface of the seat 11, forming an acute angle or being parallel to it, and the support assembly 2 is in a retracted state, making it convenient for dragging. As shown in Figure 26, in this mode, 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. As shown in Figure 27, in this mode, the backrest assembly 12 is flipped and unfolded relative to the seat 11, the support assembly 2 is in a retracted state, and the handle assembly 4 extends relative to the backrest assembly 12.

[0079] As shown in Figures 10-12, in order to achieve a linkage release to facilitate the unlocking operation, a handle assembly 4 is further included. The handle assembly 4 is slidably disposed on the backrest assembly 12. The backrest locking mechanism 13 is configured to be linked with the handle assembly 4 to release the lock when the handle assembly 4 slides to a preset position relative to the backrest assembly 12. In this embodiment, when the handle assembly 4 is operated to slide downward relative to the backrest assembly 12, the lower end of the handle assembly 4 presses against the backrest locking block 132 and slides downward, causing the locking end of the backrest locking block 132 to exit the backrest locking hole 131, as shown in Figure 12, thereby releasing the backrest assembly from being locked relative to the seat, and the backrest assembly can be operated to flip and fold toward the seat.

[0080] As shown in Figures 15, 17, and 18, to facilitate unlocking operations, the child carrier further includes a use-state locking mechanism 5. The use-state locking mechanism 5 is configured to lock the child carrier in either the stroller use state or the car seat use state. The use-state locking mechanism 5 is configured to be released in conjunction with the backrest assembly 12 when the backrest assembly 12 is tilted forward to a predetermined angle relative to the seat portion 11. In this embodiment, when the backrest assembly is tilted toward the seat portion, the backrest assembly 12 is released in conjunction with the stroller state locking mechanism 51 of the use-state locking mechanism 5. This releases the stroller state locking mechanism 51 without the user having to operate the unlocking mechanism. This allows the unfolded front leg assembly 21 and rear leg assembly 22 to be retracted, allowing the child carrier to quickly switch from the stroller use state to the car seat use state.

[0081] As shown in Figures 1, 2, and 17-20, the backrest assembly 12 includes a backrest 121 rotatably connected to the seat 11 and a side connection 122 connected to the seat 11.

When adjusting and unlocking, the user presses the handlebar adjustment unlocking button 413 to link the handlebar adjustment locking block 412 to slide relative to the handlebar assembly 4, so that the locking end of the handlebar adjustment locking block 412 exits the handlebar adjustment locking hole 411. At this time, the handlebar assembly 4 can be operated to slide upward or downward relative to the side connection part 122. When it is adjusted to the desired position, release the handlebar adjustment unlocking button 413, and adjust the locking block elastic part to make the locking end of the adjustment locking block 412 insert into the corresponding handlebar adjustment locking hole 411.

[0088] As shown in Figures 14, 16, 19 and 21, the handle assembly 4 is provided with a backrest blocking assembly 42 that can prevent the backrest portion 121 from flipping backward relative to the side connection portion 122. A handlebar anti-foolproof locking mechanism 43 is provided between the handle assembly 4 and the side connection portion 122 for locking the handlebar assembly 4 relative to the side connection portion 122 when the backrest blocking assembly 42 releases the blocking of the backrest portion 121. The handlebar anti-foolproof locking mechanism 43 is configured to be unlocked by the backrest portion 121 when the backrest portion 121 flips forward to a preset position relative to the side connection portion 122. In this embodiment, when the handle assembly 4 is not pulled out so that the backrest blocking assembly 42 and the backrest 121 are blocked, the backrest 121 cannot be flipped backward relative to the side connecting portion 122, and the backrest assembly 12 and the seat 11 can only achieve an opening and closing angle of 0-98°, as shown in Figures 1 and 2; when the backrest blocking assembly 42 of the handle assembly 4 is pulled out to remove the blocking of the backrest 121, the backrest 121 of the backrest assembly 12 can be flipped backward relative to the side connecting portion 122, that is, the backrest 121 of the backrest assembly 12 and the seat 11 can achieve an opening and closing angle of 0-158°, as shown in Figure 28.

[0089] In this embodiment, the backrest blocking assembly 42 is used in conjunction with the handle anti-foolproof locking mechanism 43, so that the handle assembly 4 and the backrest 121 are interlocked to ensure reliability in use.

[0090] As shown in Figures 16 and 19, the handle anti-foolproof locking mechanism 43 includes a handle anti-foolproof locking hole 431 provided on the handle assembly 4 and a handle anti-foolproof locking pin 432 slidably provided on the side connecting portion 122 and capable of being inserted into the handle anti-foolproof locking hole 431. A handle anti-foolproof elastic member 433 is provided between the handle anti-foolproof locking pin 432 and the side connecting portion 122, which enables the handle anti-foolproof locking pin 432 to be elastically inserted into the handle anti-foolproof locking hole 431; the handle anti-foolproof locking pin 432 is configured to be unlocked by the backrest portion 121 when the backrest portion 121 is flipped forward to a preset position relative to the side connecting portion 122. When adjusting the backrest 121 to flip backward relative to the side connection part 122, it is necessary to first operate the handle assembly 4 to slide upward relative to the side connection part 122, so that the backrest blocking assembly 42 cancels the blocking of the backrest 121, and at the same time, the handle anti-foolproofing locking pin 432 is inserted into the handle anti-foolproofing locking hole 431 to lock the handle assembly 4, as shown in Figures 1 and 2. At this time, the user can operate the backrest 121 to flip backward relative to the side connection part 122, that is, to flip within 98°-158°, as shown in Figure 28; when it is necessary to operate the handle assembly 4 to retract the side connection part 122, it is necessary to first operate the backrest 121 to flip forward relative to the side connection part 122 to a preset position, and the backrest 121 links the handle anti-foolproofing locking pin 432 to unlock, thereby releasing the handle anti-foolproofing locking mechanism 43 from locking the handlebar assembly 4.
