Description

[Technical Field] This application relates to the field of infant and child products, and more particularly to a foldable car seat. [Background Technology] A car seat with a baby carrier is a type of car safety seat designed for infants and toddlers to ensure the safety and comfort of children while traveling. Existing baby carriers generally adopt a one-piece shell structure. While this design performs well in terms of safety and stability, it has a series of significant drawbacks when it comes to storage and carrying.

[0001] First, the one-piece design results in a large volume of basket-style car seats. When not in use, basket-style car seats cannot be effectively folded or disassembled, causing them to take up a lot of space when stored at home or in the car. This is especially inconvenient for small cars or families with limited space. Many families may find that even in the trunk, basket-style car seats are not easy to place. The large volume of basket-style car seats not only takes up too much storage space, but may also cause other items to be squeezed and damaged, resulting in wasted space and inconvenience in use.

[0002] Secondly, the integrated design also limits the flexibility of storage methods. Sufficient space is required when storing, and the large overall size of the basket-style car seat makes it difficult for users to place it in a drawer or a corner of the trunk. This not only increases the difficulty of storage, but may also cause obstacles for families when storing other items.

[0003] Furthermore, the overall structure of the infant car seat makes it inconvenient to carry, especially when getting in and out of the car. Parents not only need to carry the baby, but also need to lift the relatively heavy infant car seat, which requires greater strength and coordination. This is especially difficult when operating in the confined space of the car. In emergency or quick situations of getting in and out of the car, the large size of the infant car seat may further increase the complexity and difficulty of operation. For families who travel frequently, carrying such a bulky device not only brings great trouble, but also seriously affects the overall user experience.

[0004] This invention was proposed in response to the shortcomings of existing technologies. [Summary of the Invention] The existing basket-type car seat mentioned above is usually a single, integral shell, which makes it bulky, inconvenient to carry, and takes up a lot of space when stored and carried.

[0005] This application is achieved through the following technical solutions: A foldable basket-style car seat, comprising: The seat body assembly is designed to support the child; A main body support assembly is located at the bottom of the seat main body assembly, and the main body support assembly has a support position and a folding position; A linkage component is disposed between the seat body assembly and the body support assembly. The linkage component enables the seat body assembly to move relative to the body support assembly to a support position or a folded position, so that the body support assembly can switch to a support state or a folded state on the seat body assembly. A limiting component is disposed between the seat body assembly and the body support assembly, the limiting component enabling the body support assembly to be restricted to a supporting position or a folded position on the seat body assembly.

[0006] Compared with the prior art, this application has the following advantages: This invention relates to a foldable infant car seat, specifically a car seat for infants and toddlers. It includes a seat body assembly, a body support assembly, a linkage assembly, and a limiting assembly. When the user needs to use the seat, the linkage assembly moves the seat body assembly relative to the body support assembly from a folded position to a supported position, thus activating the infant car seat to a supported state. The limiting assembly then locks the seat body assembly in the supported position on the body support assembly. When the user no longer needs the infant car seat, the linkage assembly can be operated again to move the seat body assembly relative to the body support assembly from the supported position to a folded position. When the body support assembly is fully folded, the limiting assembly locks the seat body assembly in the folded position on the body support assembly. This foldable design allows the car seat to be folded into a smaller volume when not in use, improving space utilization efficiency. [Attached Image Description] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

Detailed Implementation Methods

[0008] like Figures 1 to 10 As shown, a foldable basket-style car seat according to this embodiment includes: Seat body assembly 1, which can support a child; The main body support assembly 2 is located at the bottom of the seat main body assembly 1, and the main body support assembly 2 is provided with a support position 21 and a folding position 22. Linkage component 3 is disposed between the seat body assembly 1 and the body support assembly 2. The linkage component 3 enables the seat body assembly 1 to move relative to the body support assembly 2 to the support position 21 or the folded position 22, so that the body support assembly 2 can switch to the support state or the folded state on the seat body assembly 1. The limiting component 4 is disposed between the seat body assembly 1 and the body support assembly 2. The limiting component 4 can restrict the body support assembly 2 on the seat body assembly 1 to the supporting position 21 or the folded position 22.

[0009] Specifically, when a user needs to use the seat, by operating the linkage component 3, the seat body component 1 is moved from the folded position 22 to the supporting position 21 relative to the body support component 2. That is, through the linkage component 3, the body support component 2 will gradually unfold on the seat body component 1 and support the bottom of the seat body component 1, so that the basket-type car seat is converted to the supporting state. Furthermore, the limiting component 4 locks the seat body component 1 in the supporting position 21 on the body support component 2, ensuring that the basket-type car seat is in a stable supporting state and preventing accidental folding during use.

[0010] When the user no longer needs to use the basket-style car seat, the user can operate the linkage component 3 again to move the seat body component 1 from the supporting position 21 to the folded position 22 relative to the body support component 2. Under the action of the linkage component, the body support component 2 will fold up on the seat body component 1 from the supporting position, and the basket-style car seat will become more compact.

[0011] When the main support assembly 2 is fully folded on the seat main assembly 1, the limiting assembly 4 locks or temporarily positions the seat main assembly 1 at the folded position 22 on the main support assembly 2 to prevent the seat from unfolding on its own.

[0012] Preferably, in other embodiments, the limiting component 4 will only lock the seat body component 1 at the support position 21 on the body support component 2, and will not lock or temporarily position the seat body component 1 at the folded position 22 on the body support component 2. A suitable design can be selected according to actual needs.

[0013] Specifically, through the linkage and limiting components, users can easily switch the infant car seat from the supported state to the folded state without complicated operations. It has the advantages of simple structure and convenient operation. Due to its simple design and easy operation, parents do not need to spend too much time assembling or disassembling the seat, thereby reducing troubles during use and improving the overall user experience.

[0014] Specifically, the limiting components ensure that the seat will not fold unexpectedly when in the supported position, thus guaranteeing the seat's safety.

[0015] With its foldable design, the basket-style car seat can be folded down to a smaller size when not in use. The folded-down basket-style car seat can be easily placed in the trunk of a car or in a home storage cabinet without taking up too much space or interfering with the placement of other items, thus improving the efficiency of space utilization. It is easy to carry and store, especially for small cars with limited space or families with insufficient storage space at home, this design greatly alleviates storage problems.

[0016] Furthermore, this type of basket-style car seat is not only suitable for use in cars, but can also be easily carried to other scenarios, such as travel, short trips, or picnics. Its lightweight and foldable features make the seat a multifunctional product for daily family life.

[0017] like Figures 1 to 10 As shown, the linkage component 3 in this embodiment includes a first rotating component, which enables the main body support component 2 and the seat body component 1 to be rotatably connected.

[0018] When the user wishes to use the seat, the main body support assembly 2 begins to rotate relative to the seat body assembly 1 through the first rotating component. During the rotation, the main body support assembly gradually transitions from a folded state to an unfolded state, so that the seat body is stably supported. After rotating to the correct position, the seat body assembly 1 is locked in the support position 21 on the main body support assembly 2 by the limiting component 4, and the basket-style car seat enters the normal use state.

[0019] When not in use, the user can unlock the seat body assembly 1 and the body support assembly 2 through the limiting component 4. Using the first rotating component, the body support assembly 2 rotates in the opposite direction to the seat body assembly 1. The rotating component causes the body support assembly 2 to start rotating relative to the seat body assembly 1, and the body support assembly 2 gradually folds back from the supporting position 21 to the folded position 22. The body support assembly 2 folds back onto the seat body assembly 1, and the basket-style car seat is compactly stored. After folding, the limiting component 4 restricts the seat body assembly 1 to the folded position 22 on the body support assembly 2 to prevent the basket-style car seat from accidentally unfolding when not in use.

[0020] Specifically, through the first rotating component, the main body support assembly 2 and the seat body assembly 1 can achieve a smooth and easy rotational connection, which makes the folding and unfolding process of the basket-type car seat more intuitive and labor-saving, without the need for complicated manual operation.

[0021] Furthermore, the first rotating component ensures a more stable connection between the main support assembly 2 and the seat main assembly 1, reducing instability caused by loosening or swaying of the support components. During unfolding or folding, the rotating connection ensures smooth operation and safety.

[0022] In other embodiments, the linkage component 3 may also be a sliding component, which enables the body support component 2 and the seat body component 1 to be slidably connected.

[0023] When a user wishes to use the basket-style car seat, the main support component 2 can slide relative to the seat main body component 1 along a predetermined track via the sliding component. During the sliding process, the seat main body component 1 gradually slides from the folded position 22 to the support position 21 relative to the main support component 2. The basket-style car seat gradually unfolds and is stably supported. After the basket-style car seat is unfolded into place, the limiting component 4 locks the seat main body component 1 in the support position 21 on the main support component, and the basket-style car seat is ready for normal use.

[0024] When the seat is not in use, the user can slide the main support assembly 2 in the opposite direction again by sliding the sliding component. The main support assembly 2 can slide relative to the seat main assembly 1 from the support position 21 to the folded position 22 along the track. At the same time, the basket-style car seat gradually folds up. After the sliding is completed, the limiting component 4 locks the seat main assembly 1 in the folded position 22 on the main support assembly to ensure that the seat will not be accidentally unfolded when stored.

[0025] Preferably, the sliding component design allows the main support assembly 2 to move smoothly along the track on the seat main assembly 1, making the unfolding and folding process very smooth and requiring no force. The sliding connection effectively reduces friction and resistance, improving the user experience.

[0026] Users can fold and unfold the seat by simply pushing or pulling the seat assembly along the track. This method is especially suitable for quick adjustments, allowing users to easily switch seats.

[0027] Preferably, the linkage component 3 may also adopt the following structure: Pneumatic or hydraulic components use compressed air or liquid pressure to provide smooth folding and unfolding movements, and hydraulic or pneumatic rods help the seat unfold and fold slowly and steadily.

[0028] Chain or gear mechanism: Using a chain or gear system, the unfolding and folding of the seat is controlled by gear meshing or chain pulling. Users can operate the gears by rotating the handle or pressing the button to move the support components along the set track.

[0029] The electric system uses a motor to drive the seat to unfold and fold. Users only need to press a button, and the motor will drive the linkage components to operate automatically.

[0030] You can choose the appropriate design based on your needs.

[0031] like Figures 1 to 10 As shown, the first rotating component of this embodiment includes a first rotating hole 31 provided on the main body support assembly 2 and a second rotating hole 32 provided on the seat body assembly 1. The first rotating hole 31 and the second rotating hole 32 are provided correspondingly. The first rotating component also includes a rotating shaft, which passes through the second rotating hole 32 and extends into the first rotating hole 31. It has the advantages of simple structure and convenient operation.

[0032] Preferably, in this embodiment, the first rotating component is positioned off-center at the foot of the basket-type car seat, meaning that the rotating connection is made near the bottom of the seat. This helps to lower the overall center of gravity of the seat, making the seat more stable when unfolded or folded, less prone to tipping over, and providing more balanced support.

[0033] Furthermore, the off-center design makes the seat more compact when folded, facilitating storage and transportation, and is especially suitable for small cars or spaces with limited space.

[0034] like Figures 1 to 10As shown, the limiting component 4 in this embodiment includes a limiting drive component 43 and a first limiting protrusion 41 that is linked with the limiting drive component 43. The first limiting protrusion 41 can restrict the movement of the body support component 2 relative to the seat body component 1. Preferably, when the limiting drive component 43 is operated, the limiting drive component 43 drives the first limiting protrusion 41 to release the restriction on the body support component 2 and / or the seat body component 1.

[0035] Preferably, the limiting component 4 in this embodiment further includes a first limiting hole 42, the first limiting protrusion 41 is disposed on the limiting driving member 43, the first limiting hole 42 is disposed on the support position 21, and the limiting driving member 43 can drive the first limiting protrusion 41 to be inserted into the first limiting hole 42, or drive the first limiting protrusion 41 to be dislodged from the first limiting hole 42.

[0036] Specifically, when the user unfolds the seat, the linkage component between the seat body assembly 1 and the body support assembly 2 moves, unfolding the seat body assembly 1 relative to the body support assembly 2 to the designated support position 21. When the seat body assembly 1 is unfolded relative to the body support assembly 2 to the designated support position 21, the user can operate the limit drive component 43 to drive the first limit protrusion 41 to engage with the first limit hole 42 located at the support position 21.

[0037] Preferably, in this embodiment, the first limiting protrusion 41 is also provided with a guide member. When the seat body assembly 1 moves to the support position 21 relative to the body support assembly 2, the user does not necessarily need to operate the limiting drive member 43. The first limiting protrusion 41 can also automatically engage with the first limiting hole 42 through the guide member. With this design, the situation where the first limiting protrusion 41 does not engage with the first limiting hole 42 due to the user's negligence can be avoided.

[0038] Preferably, the guide member includes a guide ramp 411 disposed on one end of the first limiting protrusion 41, and the guide ramp 411 is inclined inward from bottom to top towards the limiting drive member 43. When the main body support assembly 2 gradually unfolds relative to the seat main body assembly 1 to the designated support position 21, the outer side of the main body support assembly 2 will move relative to the guide ramp 411 on the first limiting protrusion 41, and gradually force the first limiting protrusion 41 to move away from the main body support assembly 2 through the guide ramp 411 until the first limiting protrusion 41 is aligned with the first limiting hole 42. At this time, the limiting drive member 43 will drive the first limiting protrusion 41 to reset through its own reset mechanism and lock into the first limiting hole 42. The user does not operate the limiting drive member 43 at this time.

[0039] Preferably, the main body support component 2 is provided with an abutting slope 27 corresponding to the guide slope 411. By abutting the guide slope 411 with the abutting slope 27, the main body support component 2 can force the first limiting protrusion 41 to move. The synergistic effect of the two slopes makes the movement of the first limiting protrusion 41 smoother and can minimize damage to the first limiting protrusion 41 and extend the service life of the first limiting protrusion 41.

[0040] Preferably, the user can also operate the limiting drive component 43 to drive the first limiting protrusion 41 to engage with the first limiting hole 42 located at the support position 21. The user can choose a suitable method to operate.

[0041] By adopting the design of the first limiting protrusion 41 and the first limiting hole 42 described above, the seat body assembly 1 and the body support assembly 2 are locked, ensuring that the basket-type car seat is firmly held in the unfolded position and will not fold due to external force or accidental operation.

[0042] In some other embodiments, the first limiting protrusion 41 is not provided with a guide member. The user must operate the limiting drive member 43 to make the first limiting protrusion 41 engage with the first limiting hole 42. A suitable design can be selected according to actual needs.

[0043] When the user needs to fold the seat, the limit drive component 43 can be operated to drive the first limit protrusion 41 to exit from the first limit hole 42, thereby unlocking the seat body assembly 1 and the body support assembly 2. At this time, the seat body assembly 1 can fold relative to the body support assembly 2 and safely fold to the folded position 22. At this time, the basket-style car seat is switched to the folded state. The whole process is smooth and controlled.

[0044] Specifically, through the mechanical locking of the first limiting protrusion 41 and the first limiting hole 42, the basket-type car seat can remain stable when unfolded to the support position, and will not fold unexpectedly due to misoperation or external pressure, thus ensuring safety during use. In addition, the interlocking design between the first limiting protrusion 41 and the first limiting hole 42 provides strong physical support, preventing the basket-type car seat from shaking or sliding during use, and enhancing the overall stability of use.

[0045] Preferably, in this embodiment, the first limiting hole 42 is a through hole, which facilitates the insertion of the first limiting protrusion 41 into the first limiting hole 42 to achieve locking, ensuring that the main body support assembly 2 is stably restricted in the support state on the seat main body assembly 1, thus providing a better support effect.

[0046] The through-hole structure allows the first limiting protrusion 41 to be easily inserted into the hole, reducing the difficulty of installation and operation. Due to the shape design of the through-hole, the first limiting protrusion 41 can be fully embedded in the hole, thereby providing a stronger physical contact area. This tight contact can effectively prevent accidental loosening or sliding during use, enhancing the locking effect of the basket-style car seat.

[0047] Specifically, the through-hole design of the first limiting hole 42 ensures that the support component can be firmly restrained in the support state, providing better support effect. Whether the child sits down or gets up, the stability of the infant car seat can be effectively guaranteed.

[0048] In other embodiments, the first limiting hole 42 may also be a blind hole with a cross-sectional shape of cone or sphere, and a suitable design can be selected according to actual needs.

[0049] Preferably, the limiting drive component 43 in this embodiment includes a sliding block 431 slidably connected within the seat body assembly 1 and a reset unit 432 disposed between the sliding block 431 and the seat body assembly 1. The first limiting protrusion 41 is disposed on one side of the sliding block 431. The sliding block 431 is provided with an operating component 433 for user operation. The user can manipulate the operating component 433 to make the sliding block 431 slide away from the body support component 2 within the seat body assembly 1. The first limiting protrusion 41 slides away from the body support component 2 along with the sliding block 431. If the first limiting protrusion 41 is located within the first limiting hole 42 at this time, the first limiting protrusion 41 exits the first limiting hole 42.

[0050] When the force on the operating member 433 is removed, the reset unit 432 can drive the sliding block 431 to slide towards the main body support component 2. The first limiting protrusion 41 slides towards the main body support component 2 along with the sliding block 431. If the first limiting protrusion 41 is aligned with the first limiting hole 42 at this time, the first limiting protrusion 41 can be engaged in the first limiting hole 42.

[0051] Preferably, in this embodiment, when the sliding block 431 slides away from the main support component 2 within the seat body assembly 1, the first limiting protrusion 41 slides away from the main support component 2 along with the sliding block 431, and the first limiting protrusion 41 can retract into the seat body assembly 1. When the sliding block 431 slides closer to the main support component 2, the first limiting protrusion 41 slides closer to the main support component 2 along with the sliding block 431, and the first limiting protrusion 41 can extend out of the seat body assembly 1. This has the advantages of simple structure and convenient operation.

[0052] In other embodiments, a portion of the first limiting protrusion 41 is retracted into the seat body assembly 1, and the portion of the first limiting protrusion 41 exposed outside the seat body assembly 1 (e.g., the size of the portion of the first limiting protrusion 41 exposed outside the seat body assembly 1 is smaller than the gap between the seat body assembly 1 and the body support assembly 2) does not hinder the relative movement of the seat body assembly 1 and the body support assembly 2. A suitable design can be selected according to the actual situation.

[0053] Preferably, the operating component 433 in this embodiment includes a pulling groove provided on the sliding block 431. The user can pull the sliding block 431 by pulling the groove, which has the advantages of simple structure and convenient operation. In other embodiments, the operating component 433 may also adopt a rope, pulling protrusion or other structural design, and a suitable design can be selected according to the actual situation.

[0054] Preferably, the reset unit 432 in this embodiment includes a spring positioning protrusion 4321 disposed in the seat body assembly 1, a spring positioning groove 4322 disposed on the sliding block 431, and an elastic spring disposed between the two. One end of the elastic spring extends into the spring positioning groove 4322 and abuts against the side wall of the sliding block 431. The other end of the elastic spring is sleeved on the outside of the spring positioning protrusion 4321. When the sliding block 431 slides away from the body support assembly 2 in the seat body assembly 1, the elastic spring is elastically compressed under the pressure of the sliding block 431. When the force on the operating member 433 is removed, the elastic spring elastically recovers and forces the sliding block 431 to slide closer to the body support assembly 2, so that the sliding block 431 is reset to the initial position. It has the advantages of simple structure and convenient operation.

[0055] Preferably, in other embodiments, the operation mode of the limit drive component 43 can also be designed as a mechanical button, a pneumatic device, or even an electric control component. Users can easily lock or unlock the seat by pressing or rotating the relevant component, which can adapt to different usage scenarios and design requirements.

[0056] like Figures 1 to 10 As shown, the limiting component 4 in this embodiment includes a second limiting protrusion 44 and a second limiting hole 45. The second limiting hole 45 is located at the folded position 22, and the second limiting protrusion 44 is located on the seat body assembly 1. Alternatively, the second limiting protrusion 44 is located at the folded position 22, and the second limiting hole 45 is located on the seat body assembly 1. When the seat body assembly 1 moves relative to the body support assembly 2 to the folded position 22, the second limiting protrusion 44 can be engaged in the second limiting hole 45 to restrict the seat body assembly 1 to the folded position 22.

[0057] Specifically, the second limiting protrusion 44 can be located on the seat body assembly 1 or the folded position 22. Its shape and size design must match the second limiting hole 45 so that it can be smoothly inserted into the hole when the seat is folded. Its shape can be cylindrical, conical or other suitable shape to ensure that it can be freely inserted into the limiting hole when the seat is moved.

[0058] The second limiting hole 45 is located on the folded position 22 or on the seat body assembly 1. The corresponding design should ensure that when the seat body assembly 1 moves to the folded position, the second limiting protrusion can be fully inserted into the hole to achieve physical locking.

[0059] When the user operates the seat, moving the seat body assembly 1 relative to the body support assembly 2 to the predetermined folding position 22, the second limiting protrusion 44 automatically inserts into the second limiting hole 45. This locking process is also achieved through a mechanical structure, without the need for additional drive components. This automatic locking helps ensure the stability of the seat in the folded state and prevents it from being accidentally unfolded during movement or storage.

[0060] When the user needs to unfold the seat, by manually moving the seat body assembly 1 relative to the body support assembly 2, the second limiting protrusion 44 will automatically disengage from the second limiting hole 45 under the action of external force, thereby releasing the locking state and allowing the seat to unfold smoothly.

[0061] By designing an automatic locking mechanism, users do not need to take any extra steps when folding the seats, simplifying the usage process and improving convenience. Due to the simplification of this design, complex mechanical parts are reduced, the probability of failure is lowered, thereby reducing maintenance needs and costs.

[0062] like Figures 1 to 10 As shown, the inner wall of the second limiting hole 45 in this embodiment has a certain curvature, and the outer wall of the second limiting protrusion 44 has a certain curvature. The curvature of the inner wall of the second limiting hole 45 is similar to or the same as the curvature of the outer wall of the second limiting protrusion 44. With this design, it is easy for the second limiting protrusion 44 to engage or disengage from the second limiting hole 45, so as to realize the rapid conversion of the main body support assembly 2 to the folded state on the seat body assembly 1.

[0063] Specifically, the inner wall of the second limiting hole 45 and the outer wall of the second limiting protrusion 44 have similar or the same curvature, or the inner wall of the second limiting hole 45 and the outer wall of the second limiting protrusion 44 are provided with cooperating inclined surfaces in the folding and unfolding direction. That is, a first inclined surface is provided on the inner wall of the second limiting hole 45, and a second inclined surface corresponding to the first inclined surface is provided on the outer wall of the second limiting protrusion 44. The first inclined surface can cooperate with the second inclined surface. This design can help the second limiting protrusion 44 enter the second limiting hole 45 more smoothly when the seat body assembly 1 moves and folds relative to the body support assembly 2, and also facilitates its easy disengagement when unlocking.

[0064] This design allows the main support component 2 to be temporarily positioned on the seat main component 1 (i.e., not fully locked), enabling users to quickly and effortlessly unlock the basket-style car seat from the folded state to the convertible state. It has the advantages of simple structure and convenient operation.

[0065] like Figures 1 to 10 As shown, the number of limiting components 4 in this embodiment is two sets, and the two sets of limiting components 4 are arranged opposite to each other.

[0066] Specifically, each set of limiting components includes a first limiting protrusion 41, a first limiting hole 42, a limiting drive member 43, a second limiting protrusion 44, and a second limiting hole 45, which are used to limit and lock the seat in the unfolded and folded states, respectively.

[0067] The two sets of limiting components are arranged opposite each other, which usually means that they are arranged in symmetrical positions on the seat body (such as the sides or ends of the seat) to provide a balanced limiting effect.

[0068] By setting limiting components on both sides, the seat is ensured that it will not shift or become unstable due to unilateral force during operation. This symmetrical arrangement helps to improve the stability of the overall structure, especially during folding and unfolding, ensuring even engagement and disengagement.

[0069] When the seat is unfolded to the designated position, the first limiting protrusions 41 of the two sets of limiting components are simultaneously inserted into the first limiting holes 42 under the action of the corresponding limiting drive members 43, ensuring that the seat is securely locked in the support position. The two sets of limiting components arranged opposite to each other can effectively prevent the seat from tilting or being locked on one side, further improving the reliability of locking.

[0070] Similarly, when the seat is folded to the storage position, the two sets of limiting drive components 43 drive the corresponding first limiting protrusion 41 to exit the first limiting hole 42, and the seat is folded to the designated position. At the same time, the second limiting protrusion 44 of the two sets of limiting components enter the second limiting hole 45, ensuring that the seat remains stable in the folded state and will not be accidentally unfolded.

[0071] like Figures 1 to 10 As shown, the seat body assembly 1 of this embodiment includes a main backrest 11. The main backrest 11 is provided with a storage space 12 that can accommodate the body support assembly 2. The bottom of the main backrest 11 is provided with an extension hole 13 that communicates with the storage space 12. The extension hole 13 allows the body support assembly 2 to extend out of or retract into the storage space 12.

[0072] Specifically, by designing a storage space 12 on the main backrest 11, the main support component 2 can be effectively stored, thus achieving an integrated design for the seat.

[0073] Specifically, the storage space 12 is located inside the main backrest 11, which is large enough to accommodate the main support component 2. This design allows the main support component 2 to be folded up on the main backrest 11, making the basket-style car seat more compact and aesthetically pleasing, and suitable for storage in small spaces.

[0074] The extension hole 13 is located at the bottom of the main backrest 11 and is directly connected to the storage space 12. This means that when the main support component 2 needs to be unfolded or folded, it can be smoothly extended or retracted into the storage space through the extension hole 13, ensuring the smooth transition of the seat in different states.

[0075] When the seat is folded down, the main support component 2 will retract into the storage space 12 through the extension hole 13 of the main backrest 11, reducing the space occupied by the basket-style car seat when not in use.

[0076] When the seat needs to be unfolded, the user can easily extend the main support component 2 from the extension hole 13 and lock it in the predetermined position. The design of the extension hole 13 allows the support component to slide smoothly and ensures its stability after unfolding.

[0077] Preferably, in this embodiment, the linkage component 3 is positioned on the basket-type car seat such that when the main support component 2 is retracted into the storage space 12, its top is lower than or close to the top of the seat main component 1. This design ensures that the main support component 2 can be retracted into the storage space 12, guaranteeing a compact structure when the basket-type car seat is folded down. It also ensures that the main support component 2 does not protrude beyond the outer side of the seat main component 1, allowing the seat main component 1 to protect the main support component 2 from damage caused by collisions or other factors, and preventing the protruding part of the main support component 2 from hitting people or other objects.

[0078] like Figures 1 to 10As shown, the main support assembly 2 of this embodiment includes an auxiliary backrest 23 and a support part 24 arranged sequentially from top to bottom. The main backrest 11 is provided with a support space that can accommodate a child, and the storage space 12 is a support space. When the seat main assembly 1 moves relative to the main support assembly 2 to the support position 21, the top of the auxiliary backrest 23 can be tightly combined with the inner back wall of the main backrest 11 to form an integral backrest. When the seat main assembly 1 moves relative to the main support assembly 2 to the folded position 22, the auxiliary backrest 23 and the support part 24 are stored in the support space and the protrusion hole 13.

[0079] Specifically, the auxiliary backrest 23 is located on top of the main support assembly 2. When the seat main assembly 1 moves to the support position 21 relative to the main support assembly 2, the top of the auxiliary backrest 23 can be tightly combined with the inner back wall of the main backrest 11 to form an integral backrest, providing the user with comfortable back support. At this time, the basket-style car seat is converted to the unfolded state. This design not only enhances the support capacity of the basket-style car seat when unfolded, providing the user with a larger back support surface and improving the comfort and stability of the seat, but also ensures that the auxiliary backrest 23 can be smoothly stored in the support space 12 when folded.

[0080] Specifically, the main backrest 11 is provided with a support space that can accommodate a child. When the infant car seat is unfolded, the support space can support the child in combination with the backrest system of the auxiliary backrest 23 and the main backrest 11. When the infant car seat is folded up, the support space can provide storage space for the main support component 2. The function of this space is flexible and versatile in different states.

[0081] Specifically, the support part 24 is located below the auxiliary backrest 23 and serves as the main support structure of the seat. When the seat is folded down, part of the support part 24 can be stored in the storage space 12 (i.e., the support space) and the extension hole 13 through the extension hole 13 of the main backrest 11, thereby achieving compact storage of the basket-style car seat.

[0082] By designing the auxiliary backrest 23 and the support 24 as a support space 12 that can be folded into the main backrest 11, the compactness of the seat in the folded state is greatly improved. This design makes the seat take up less space when stored, making it easy to carry and store. Specifically, by adopting this design, the seat body assembly 1 and the body support assembly 2 can be folded together without compromising the overall strength of use, so that the basket-style car seat can achieve the minimum volume, which has the advantages of being easy to carry and easy to store.

[0083] Specifically, most or all of the main support components 2 are housed within the support space and the extension hole 13, which reduces the volume of the basket-type car seat by about 50%, minimizing the folded volume of the basket-type car seat and making it easier for users to carry it. Furthermore, as can be seen from the above description, the basket-type car seat can be folded up and its volume reduced with simple operation, without disassembling any parts, and the operation steps are simple.

[0084] like Figures 1 to 10 As shown, the main body support assembly 2 of this embodiment includes two basket support legs 25 arranged opposite to each other. The two basket support legs 25 are respectively arranged on both sides of the main backrest 11, and the two basket support legs 25 correspond one-to-one with the extension hole 13. Each basket support leg 25 includes an auxiliary backrest 23 and a support part 24 arranged sequentially from top to bottom.

[0085] Specifically, each basket-style car seat is equipped with two opposing basket support feet 25, located on both sides of the main backrest 11. This opposing arrangement provides good support and balance, ensuring the stability of the basket-style car seat during use.

[0086] The two basket support feet 25 correspond to the extension holes 13 on the main backrest, meaning that when the seat is folded down, each basket support foot 25 can be smoothly retracted into the storage space 12 inside the seat through the extension holes 13.

[0087] Specifically, each basket support leg 25 includes a backrest 23 and a support part 24 from top to bottom. The structural design of the backrest 23 and the support part 24 ensures that when the seat is unfolded, the backrest 23 can be tightly integrated with the main backrest 11 to provide an overall backrest support. The support part 24 is mainly responsible for the bottom support of the seat, ensuring that the seat is stable and durable when in use.

[0088] When the seat is in the unfolded position, two basket support legs 25 extend from the main backrest 11, and two auxiliary backrests 23 are tightly connected to the inner side of the main backrest 11 to form a stable overall backrest, while two support parts 24 unfold at the bottom to provide stable support.

[0089] When the seat needs to be folded, the two basket support legs 25 will be retracted into the storage space 12 and the extension hole 13 of the main backrest 11 through the corresponding extension hole 13. The auxiliary backrest 23 and the support part 24 are also retracted, making the basket-style car seat more compact and easier to store.

[0090] Specifically, by designing two opposing basket support feet 25, the seat provides even support and a more stable structure when unfolded, avoiding single-point stress and improving the durability and safety of the basket-type car seat.

[0091] Furthermore, the main support assembly 2 employs two opposing basket support legs 25, ensuring that the two basket support legs 25 have sufficient clearance when the basket-type car seat is in the unfolded state. This facilitates the placement of the basket-type car seat in a vehicle or other locations, especially on uneven ground, where the two basket support legs 25 can be used to level the ground, making it easier to place the basket-type car seat in the unfolded state. Additionally, by adding fixing components within the clearance space, the basket-type car seat in the unfolded state can be placed stably on the ground.

[0092] Preferably, the bottom of the support portion 24 in this embodiment has a certain curvature so that the basket-type car seat also has a cradle function, further increasing the functional versatility of the basket-type car seat.

[0093] like Figures 1 to 10 As shown, the main body support component 2 in this embodiment also includes a linkage part 26, which is connected to two basket support legs 25 respectively. The linkage part 26 can simultaneously drive the two basket support legs 25 to move.

[0094] This design connects the two basket support legs 25 together through a physical mechanism, ensuring that the two basket support legs 25 can move in coordination whether unfolding or folding. This design reduces the burden on the user during operation, allowing both unfolding and folding to be achieved with a single operation.

[0095] Thanks to the linkage 26, users can easily control the movement of both basket support legs simultaneously, reducing operating steps and improving ease of use, especially in situations where the seat needs to be frequently unfolded and folded.

[0096] like Figures 1 to 10 As shown, the linkage part 26 in this embodiment includes a linkage plate 261 located in the support space. The two ends of the linkage plate 261 are respectively connected to the corresponding basket support feet 25. The inner side wall of the back of the main backrest 11 is also provided with a receiving groove 111 for accommodating the linkage plate 261.

[0097] Specifically, the linkage plate 261, as a key component of the linkage part 26, is responsible for connecting the two basket support legs 25. Its design ensures that the two support legs can move synchronously when the seat is unfolded or folded. The inner side wall of the back of the main backrest 11 is provided with a receiving groove 111, which is specifically used to receive the linkage plate 261. When the linkage plate 261 is located in the groove, the top of the linkage plate 261 is flush with the inner side wall of the back of the main backrest 11. The design of the receiving groove not only keeps the linkage plate 261 hidden in the folded state, improving the overall aesthetics, but also allows the linkage plate 261 to be stored in the receiving groove 111, forming a whole backrest with the main backrest 11 and the auxiliary backrest 23. This avoids discomfort or damage to the user that protruding parts may cause, ensuring the safety and comfort of the user in the basket-type car seat.

[0098] Furthermore, when the linkage plate 261 is housed in the receiving groove 111 and the bottom of the linkage plate 261 abuts against the bottom of the receiving groove 111, the seat body assembly 1 and the body support assembly 2 cannot rotate relative to each other. At this time, the first limiting protrusion 42 aligns with the first limiting hole 42, and the coordinated action of the linkage plate 261 and the receiving groove 111 can also provide a positioning function for the limiting assembly 4, and can also prevent the seat body assembly 1 and the body support assembly 2 from being over-expanded, causing damage.

[0099] When the user operates the seat's unfolding or folding function, the linkage plate 261 can simultaneously transmit the force of movement to the two basket support legs 25, ensuring synchronized movement.

[0100] When the seat is unfolded, the linkage plate 261 pushes the basket support foot 25 to extend. When the seat is folded, the linkage plate 261 retracts the basket support foot 25 into the storage space 12 simultaneously, ensuring that the entire operation is smooth and consistent. The design of the linkage plate 261 allows users to perform simple maintenance and inspection, ensuring the normal operation of the linkage mechanism without disassembling multiple parts.

[0101] Preferably, the linkage part 26 in this embodiment further includes a linkage shaft 262, the two ends of which are respectively connected to the corresponding basket support feet 25.

[0102] Specifically, the linkage shaft 262 can effectively connect the two basket support feet 25, and its design allows the two basket support feet to move synchronously through the linkage shaft 262.

[0103] The two ends of the linkage shaft 262 are respectively connected to the corresponding basket support feet 25, ensuring that when the seat is unfolded or folded, the linkage shaft 262 can coordinate the movement of the two support feet 25 to achieve synchronous operation.

[0104] Specifically, the introduction of the linkage shaft 262 increases the rigidity of the linkage part 26, which can effectively transmit torque, making the basket support foot more stable during movement and reducing potential problems caused by uneven force distribution.

[0105] Specifically, the linkage shaft 262 and the linkage plate 261 are arranged opposite to each other on the main body support assembly 2, and the linkage shaft 262 and the linkage plate 261 are respectively located above and below the seat body assembly. This design enhances the rigidity of the linkage part 26 and makes the connection between the two basket support feet 25 more stable, ensuring the stability of the main body support assembly 2.

[0106] Preferably, the bottom of the seat body assembly 1 is also provided with a locking hole 14 for accommodating the linkage shaft 262. When the basket-type car seat is switched to the folded state, the linkage shaft 262 is locked into the corresponding locking hole 14 to hide the linkage shaft 262 at the bottom of the seat body assembly 1, so as to avoid the linkage shaft 262 affecting the storage of the folded basket-type car seat.

[0107] Furthermore, when the linkage shaft 262 is engaged in the corresponding locking hole 14, it can be determined that the second limiting protrusion 44 is engaged in the second limiting hole 45. Through this double-limiting structure, the basket-type car seat will not be over-folded, ensuring the service life of the basket-type car seat.

[0108] Preferably, the body support assembly 2 includes a storage section 241 and an assembly section 242, wherein the storage section 241 extends and retracts in the height direction relative to the seat body assembly 1.

[0109] Preferably, the storage section 241 can be stored in the storage space 12 and the extension hole 13 through the extension hole 13, while the assembly section 242 remains exposed outside the extension hole 13. When the basket-type car seat is in the folded state, the storage section 241 is stored in the storage space 12 and the extension hole 13 through the extension hole 13, and the assembly section 242 is a certain distance from the bottom of the seat body assembly 1. When the basket-type car seat is in the unfolded support state, the storage section 241 is dislodged from the storage space 12 through the extension hole 13, and the top of the assembly section 242 moves to abut against the bottom of the seat body assembly 1. The design of the top of the assembly section 242 abutting against the bottom of the seat body assembly 1 ensures that the basket-type car seat will not be over-unfolded, thus ensuring the service life of the basket-type car seat.

[0110] Furthermore, the assembly section 242 is provided with a connecting component 8 for connecting the car seat. The connecting component 8 and the assembly section 242 can be connected by a rotating connection or a sliding connection. When the basket-type car seat is in the folded state, the connecting component 8 is stored on one side of the assembly section 242. When the basket-type car seat is in the unfolded state, the connecting component 8 can be unfolded on the assembly section 242 to connect with the car seat. A suitable design can be selected according to actual needs.

[0111] Preferably, the connecting component 8 can adopt a connecting structure such as ISOFIX or snap-fit. In this embodiment, the connecting component 8 is a connecting plug. The connecting plug can adopt an existing structure to achieve connection with the car seat, which will not be described in detail here.

[0112] like Figures 1 to 10 As shown, the infant car seat of this embodiment also includes a footrest 5, which can provide support for the child's legs, and has a folded position and an unfolded position. A folding assembly 6 is disposed between the footrest 5 and the seat body assembly 1. The folding assembly 6 enables the seat body assembly 1 to move relative to the footrest 5 to a folded position or an unfolded position, so that the footrest 5 can be switched to a folded state or an unfolded state on the seat body assembly 1. A locking component 7 is disposed between the footrest 5 and the seat body assembly 1, and the locking component 7 enables the footrest 5 to be locked on the seat body assembly 1 in a folded or unfolded position.

[0113] Specifically, the footrest 5 can switch between a folded position and an unfolded position to meet different usage needs. When the footrest 5 is unfolded, it can provide comfortable support for children; when it is not needed, the footrest 5 can be folded to the folded position, further reducing the size of the infant car seat.

[0114] Specifically, when it is necessary to provide support for a child's legs, the user can operate the folding component 6 to unfold the footrest 5 from the folded state to an appropriate angle. At this time, the locking component 7 between the footrest and the seat body component 1 is locked to ensure that the footrest 5 will not be accidentally folded due to vehicle bumps or other external forces.

[0115] When the footrest 5 is not needed, the user can operate the folding component 6 to fold the footrest 5 from the unfolded state to the folded state, which saves space in the vehicle. After the footrest is folded, the locking component 7 will fix it in the folded position.

[0116] The folding component 6 and locking component 7 make it easy to unfold and fold the footrest 5 on the seat body component 1, allowing users to quickly adjust the seat to meet the needs of different usage scenarios.

[0117] like Figures 1 to 10 As shown, the folding component 6 in this embodiment includes a second rotating member, which enables the footrest 5 and the seat body assembly 1 to be rotatably connected; the second rotating member includes a first rotating housing 61 disposed on the footrest 5 and a second rotating housing 62 disposed on the seat body assembly 1, and the first rotating housing 61 and the second rotating housing 62 are rotatably connected.

[0118] Specifically, when the user needs to unfold the footrest 5, the footrest 5 on the first rotating housing 61 can smoothly rotate from the folded position to the unfolded position through the rotational connection of the second rotating component, that is, the rotation between the first rotating housing 61 and the second rotating housing 62.

[0119] When unfolded, the footrest 5 provides comfortable leg support for children, and when not in use, the footrest 5 can be easily folded up manually.

[0120] The footrest 5 can be flexibly switched between folding and unfolding via a rotating connection, allowing users to adjust it as needed.

[0121] Preferably, in other embodiments, the folding component 6 may also be a sliding component, so that the footrest 5 slides on the seat body component 1, and the footrest 5 slides on the seat body component 1 from the folded position to the unfolded position. A suitable design can be selected according to actual needs.

[0122] like ​ As shown, the first rotating housing 61 of this embodiment is provided with a first locking cavity 611, and the second rotating housing 62 is provided with a second locking cavity 621 corresponding to the first locking cavity 611. The locking assembly 7 includes a locking member 71 disposed in the second rotating member and a driving member 72 disposed on the second rotating member. The driving member 72 is linked to the locking member 71. When the driving member 72 drives the locking member 71 to disengage from the first locking cavity 611 and enter the second locking cavity 621, the first rotating housing 61 can rotate on the second rotating housing 62. When the locking member 71 moves and is located between the first locking cavity 611 and the second locking cavity 621, the footrest 5 is locked on the seat body assembly 1 in a folded position or an unfolded position.

[0123] Specifically, when the driving member 72 is activated, the driving member 72 will drive the locking member 71, causing the locking member 71 to disengage from the first locking cavity 611 and fully enter the second locking cavity 621. At this time, the first rotating housing 61 can rotate freely on the second rotating housing 62. In this state, the footrest 5 can be smoothly unfolded or retracted.

[0124] When the user wants to lock the footrest 5, the drive unit 72 will move the locking member 71 into the first locking cavity 611, while leaving part of the locking member 71 in the second locking cavity 621. That is, the locking member 71 moves and is located between the first locking cavity 611 and the second locking cavity 621. At this time, the locking member 71 is simultaneously located in the first locking cavity 611 and the second locking cavity 621. The first rotating housing 61 is firmly locked on the second rotating housing 62 and cannot rotate, thereby locking the footrest 5 onto the seat body assembly.

[0125] Preferably, the driving member 72 includes a driving button movably disposed on the first rotating housing 61 and an elastic member disposed between the locking member 71 and the second locking cavity 621. When the driving button is pressed, the driving button can drive the locking member 71 to move completely into the second locking cavity 621. At this time, the elastic member is in an elastic compression state. When the force on the driving button is removed, the elastic member elastically recovers and forces the locking member 71 to move towards the first locking cavity 611.

[0126] In other embodiments, the driving member 72 includes a driving button movably disposed on the first rotating housing 61, and an elastic member disposed between the driving button and the first rotating housing 61. The driving button is fixedly connected to the locking member 71. When the driving button is pressed, the driving button can drive the locking member 71 to move completely into the second locking cavity 621. At this time, the elastic member is in an elastic compression state. When the force on the driving button is removed, the elastic member elastically recovers and forces the driving button to move away from the second locking cavity 621, and drives the locking member 71 to move towards the first locking cavity 611.

[0127] Preferably, the shape of the locking member 71 is similar to or the same as the shape of the first locking cavity 611, so that the locking member 71 can be inserted into the first locking cavity 611 to lock the first rotating housing 61 and prevent it from rotating relative to the second rotating housing 62.

[0128] Preferably, the locking member 71 may be polygonal.

[0129] Preferably, the locking member 71 includes a locking ring 711 and a locking block 712 disposed on the outer side wall of the locking ring 711. The first locking cavity 611 includes a fourth locking cavity 612 for accommodating the locking ring 711 and a fifth locking cavity 613 for accommodating the locking block 712. The number of locking blocks 712 is at least one, and the number of fifth locking cavities 613 is at least two. In this embodiment, the locking block 712 and the fifth locking cavity 613 correspond one-to-one. When the locking block 712 is engaged in the corresponding fifth locking cavity 613, the footrest 5 is locked in a folded position or an unfolded position on the seat body assembly 1.

[0130] In other embodiments, there is one locking block 712 and two fifth locking cavities 613, with the folded and unfolded positions respectively located in the two fifth locking cavities 613. When the locking block 712 is engaged in the fifth locking cavity 613 with the folded position, the footrest 5 is locked in the folded position on the seat body assembly 1. When the locking block 712 is engaged in the fifth locking cavity 613 with the unfolded position, the footrest 5 is locked in the unfolded position on the seat body assembly 1.

[0131] In other embodiments, there are multiple fifth locking cavities 613. In addition to the fifth locking cavities 613 having an unfolded position and a retracted position, there are also multiple fifth locking cavities 613 with adjustable angles. When the locking block 712 is engaged in the corresponding fifth locking cavity 613, the angle of the footrest 5 on the seat body assembly 1 can be adjusted.

[0132] In other embodiments, the locking block 712 corresponds one-to-one with the fifth locking cavity 613, and there are multiple fifth locking cavities 613. In addition to the fifth locking cavity 613 having an unfolded position and a folded position, there are also multiple fifth locking cavities 613 with adjustable angles. When the footrest 5 is rotated to a certain angle and the locking block 712 can be engaged in the fifth locking cavity 613, the position of the footrest 5 on the seat body assembly 1 can be adjusted. A suitable design can be selected according to actual needs.

[0133] Preferably, in this embodiment, when the seat body assembly 1 is in the folded state, the footrest 5 is partially stored under the seat body assembly 1, or the footrest 5 can be moved downward relative to the seat body assembly 1 to the folded state. This design makes the structure of the footrest 5 and the seat body assembly 1 more compact, minimizing the volume of the basket-type car seat in the folded state.
