Description

Technical Field

[0001] This utility model relates to the field of child car seat manufacturing technology, and in particular to child car seat bases. Background Technology

[0002] As a core piece of equipment for ensuring children's safety while traveling in a car, the secure connection between child car seats and car seats or dedicated bases, as well as their ease of installation and removal, are key indicators for measuring the practicality and safety of child car seats.

[0003] Currently, some child seat bases use a single pull-to-open design for their connecting modules. This means that only one handle or operating component is placed at a specific location on the base. This component drives an internal transmission mechanism to engage or disengage the hook from the child seat. However, when assembling or disassembling a child seat, the limited operating position restricts the assembly orientation, often resulting in the handle being obstructed or in an inaccessible position. This necessitates readjusting the seat's orientation before assembly or disassembly, failing to meet diverse assembly needs. This is especially problematic in confined spaces with limited visibility, significantly increasing the user's operational difficulty and time commitment. Furthermore, the single pull-to-open structure requires high precision, demanding that users accurately locate and align the single operating component. Some products also require a specific direction of force application, making the process relatively complex. This poses inconvenience for users with limited hand strength or for quick assembly or disassembly in emergencies. Improper operation may even lead to incomplete engagement or disengagement of the connecting mechanism, creating a safety hazard.

[0004] Therefore, there is an urgent need for child seat bases, which can solve the problem of limited operating positions caused by existing single operating components, resulting in inconvenience in disassembly and assembly, and achieve flexible and convenient multi-directional operation. Utility Model Content

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] This embodiment discloses a child seat base, such as Figures 1-2 As shown, in this embodiment, the child seat base includes a base module 1 and a connecting module 2. The connecting module 2 includes a base module 1 and a connecting module 2. The connecting module 2 includes a fixing member 21, a gear 22, a hook 24, a pair of opposing linkage members 23, and a pair of opposing handles 25. The fixing member 21 is installed on the base module 1, and the gear 22 is rotatably installed on the base module 1. The fixing member 21 is spaced apart on the circumferential outer side of the gear 22. One end of the linkage member 23 along the first direction is respectively engaged with the gear 22. The rotation of the gear 22 can drive the two linkage members 23 to move towards or away from each other along the first direction. Each linkage member 23 is rotatably mounted with a hook 24 at its opposite end along the first direction. The opposite end of the hook 24 is used to engage with the child seat. The hook 24 is also rotatably connected to the fixing member 21. One end of the handle 25 along the first direction is respectively engaged with the gear 22. The opposite end of the handle 25 along the first direction is provided for hand positioning. By gripping the pull groove and pulling the handle 25, the gear 22 can be rotated. This allows the user to operate any handle 25 regardless of the orientation of the child seat on the base module 1. The meshing transmission between the handle 25 and the gear 22 drives the linkage 23 to move in the first direction. Then, through the rotational engagement of the hook 24 and the fixing part 21, the hook 24 can be engaged or disengaged from the child seat, completing the disassembly and assembly operation. This achieves high flexibility in multi-directional operation, breaking the limitations of traditional child seat disassembly and assembly on specific operating positions or directions. It adapts to different assembly needs and scenarios for child seats, while greatly improving the convenience of disassembly and assembly. There is no need to find a specific handle 25 or perform complex operations; disassembly and assembly can be completed with a single action. This effectively simplifies the operation process, reduces the difficulty of use, saves operation time and effort, and improves the user experience. At the same time, it also ensures the reliability and efficiency of connecting or separating the child seat and the base in different usage scenarios.

[0041] Preferably, such as Figures 1-2As shown, in this embodiment, the base module 1 includes a limiting protrusion 11, which is spaced apart on both sides of the gear 22 along the first direction. The connecting module 2 also includes a return spring 26, one end of which abuts against the linkage 23, and the other end of which abuts against the limiting protrusion 11. The return spring 26 is used to drive the linkage 23 and the handle 25 to return to their initial positions along the first direction after the external force is removed. After the disassembly and assembly of the handle 25 is completed, no additional manual adjustment is required. The return spring 26 will push the linkage 23 to return to its initial position along the first direction. The linkage 23 drives the handle 25 to return to its initial position synchronously through the meshing transmission with the gear 22, so that the entire connecting module 2 is restored to the initial state to be assembled or separated, improving the convenience of operation, eliminating the need for manual return of components, simplifying the operation process, and saving time and effort.

[0042] Preferably, such as Figures 1-2 As shown, in this embodiment, the handle 25 is stacked on and connected to the linkage 23. Both the handle 25 and the linkage 23 are provided with rack structures of the same specifications, and the projection positions of the tooth tips and tooth roots of the two coincide. They can mesh with the same gear 22 to achieve synchronous transmission, thereby reducing the matching requirements of the meshing accuracy of the gear 22 and the rack structure, reducing the difficulty and cost of precision control in the manufacturing and assembly process, and ensuring the stability and reliability of the transmission of the connecting module 2. This ensures that when operating any handle 25, the linkage 23 can be moved through stable transmission, thereby realizing the engagement or disengagement of the hook 24 with the child seat, improving the convenience and flexibility of the child seat disassembly and assembly, as well as the reliability and efficiency of connection or disassembly under different usage scenarios.

[0043] Optionally, such as Figures 1-2 As shown, in this embodiment, each linkage 23 is provided with two hooks 24. The hooks 24 are symmetrically distributed with the central axis of the connecting module 2 extending along the first direction as the axis of symmetry. This enables multi-point symmetrical engagement when the child seat is connected to the base module 1. The symmetrical distribution of the hooks 24 allows the child seat to be subjected to more even force during assembly, avoiding loosening of the connection or damage to components due to excessive force on one side of the hooks 24. This significantly improves the stability and reliability of the connection between the child seat and the base, and effectively disperses various external forces generated during the use of the seat. In other embodiments, each linkage 23 may be provided with one, three, or four hooks 24.

[0044] Preferably, such as Figures 1-2As shown, in this embodiment, the child seat base also includes at least one guide module 3. Guide elongated holes 31 are provided on both the linkage and the handle. The guide elongated holes 31 extend along a first direction. The guide module 3 includes guide screws 32, and a guide screw 32 is slidably disposed within each guide elongated hole 31. The guide screws 32 are fixedly screwed onto the base module 1. The cooperation between the guide elongated holes 31 and the guide screws 32 provides precise guidance for the movement of the linkage 23 and the handle 25 along the first direction. The guide module 3 can limit the linkage 23 and the handle 25 from deviating from the first direction, shaking, or jamming during movement, ensuring that both always move stably along a preset trajectory. This ensures the accuracy of the meshing transmission between the gear 22 and the linkage 23 and handle 25, avoiding situations where the hook 24 is not securely engaged with the child seat or does not separate smoothly due to component misalignment. This improves the stability and reliability of the child seat assembly and disassembly operations, reduces wear caused by component misalignment and friction, and extends the service life of the base.

[0045] Preferably, such as Figures 1-3 As shown, in this embodiment, the child seat base also includes a seat connection accessory 4, which covers the connection module 2 and fits snugly against the child seat. This provides all-around protection for the connection module 2 and ensures a tight connection between the child seat and the base, thus improving both safety and aesthetics. It prevents dust, liquids, and other foreign objects from entering the connection module 2, avoiding damage to core transmission components such as the fixing parts 21, gears 22, and hooks 24 due to contamination or accidental impacts, ensuring smooth and reliable multi-directional disassembly and assembly operations, and extending the overall lifespan of the base. Furthermore, by fitting snugly against the child seat, it fills the connection gap, reducing seat wobbling during use. It also shields the metal parts and moving structures of the connection module 2, preventing children from contacting sharp parts or accidentally touching transmission components, thus improving safety. Finally, it optimizes the base's appearance, making the overall structure simpler and more unified, enhancing the user experience during installation and use.

[0046] Preferably, such as Figures 1-2 As shown, in this embodiment, the base module 1 includes a base body 12 and a turntable 13. A limiting protrusion 11 is disposed on the turntable 13. The base body 12 is placed on the car seat, and the turntable 13 is rotatably mounted above the base body 12. The connecting module 2 is mounted on the turntable 13. The connecting module 2 can rotate relative to the base body 12 to realize the forward and reverse installation of the child seat, which can flexibly adapt to the riding needs of children of different ages, break the limitation of the fixed installation direction of existing child seats, and the rotation design of the turntable 13 ensures the stability of the switching process. The seat direction can be adjusted without disassembling the base body 12, which simplifies the operation process, reduces the difficulty of use, improves the flexibility and adaptability of use, ensures the reliability of the child seat connection under different installation directions, and optimizes the user experience.

[0047] Preferably, such as Figures 1-2 As shown, in this embodiment, the base module 1 also includes a turntable quick-release component 15. The turntable 13 quick-release component is installed on the base body 12 and engages with the turntable 13 to achieve quick disassembly and assembly of the turntable 13. This retains the flexibility of the turntable 13 in switching between forward and reverse rotation of the child seat and the advantage of easy disassembly and assembly of the connecting module 2, while further expanding the usage scenarios and storage convenience of the base. When the child seat is not in use, the turntable 13 can be quickly detached from the base body 12 by simply operating the turntable quick-release component 15 to store or carry it separately, effectively reducing the overall space occupied. At the same time, the detachable design also facilitates the cleaning, maintenance, or replacement of the turntable 13 or the base body 12 separately, reducing the later usage costs.

[0048] Preferably, such as Figures 1-2 As shown, in this embodiment, the base module 1 also includes two car seat connectors 14, which are mounted on the base body 12. The two car seat connectors 14 are symmetrically arranged about the central axis of the base body 12 extending in the first direction. The car seat connectors 14 are located at the end of the base body 12 that is relatively close to the back of the car seat in the first direction. This enables a stable and more compatible connection between the child seat base and the car seat ISOFIX interface. The symmetrical layout makes the connection between the base and the car seat more evenly stressed, avoiding loosening or instability caused by unilateral stress, thus improving the overall installation safety of the child seat. At the same time, the location close to the back of the car seat fits the installation space and structural characteristics of most car seats, making it easy for users to quickly find the installation point. Combined with the original multi-directional operation advantages, it simplifies the assembly process of the child seat base and the car seat, reduces the installation difficulty, and saves operation time. Moreover, the symmetrical design can adapt to car seats of conventional sizes in different models, enhancing the versatility of the base and ensuring stable and efficient installation in various usage scenarios.

[0049] Preferably, such as Figures 1-2As shown, in this embodiment, the child seat base also includes a stabilizing leg 5. The stabilizing leg 5 is installed at the end of the base module 1 that is relatively far from the back of the car seat along the first direction. The other end of the stabilizing leg 5 along its extension direction abuts against the floor inside the car. This can further enhance the support stability and overall structural integrity of the child seat base inside the car. When the car encounters sudden braking, acceleration, or bumpy road conditions, the stabilizing leg 5 can form a cooperative support with the base module 1, effectively dispersing and transmitting the impact and pressure generated by the child seat and the child sitting in it. This avoids the risk of displacement, tilting, or even overturning of the base due to concentrated force, and greatly improves the safety protection level when the child is riding. At the same time, the tight contact between the stabilizing leg 5 and the floor inside the car can also reduce the shaking of the child seat during driving, creating a more stable and comfortable riding environment for the child. Moreover, this design does not affect the original base's multi-directional convenient disassembly and assembly function achieved through components such as the handle 25 and gear 22. While ensuring safety and stability, it continues the flexibility and convenience of use, and better adapts to the usage needs of the child seat in different in-car scenarios.

[0050] Preferably, such as Figures 1-2 As shown, in this embodiment, the stabilizing leg 5 is a telescopic column structure, which allows the leg to flexibly adjust its length according to the actual height difference between the vehicle floor and the base module 1, ensuring that it can always be in close contact with the vehicle floor. This allows the child seat base to adapt to different vehicle models with varying interior heights, avoiding the problem of support failure or instability caused by a fixed-length leg not being able to fit the floor, greatly improving the vehicle compatibility of the child seat base. When the stabilizing leg 5 is not needed, it can be retracted to its shortest state, reducing space occupation and facilitating the transport, storage, and flexible placement of the base in the vehicle.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
