ISOFIX structure with energy absorption structure and child safety seat

Abstract

The utility model discloses an ISOFIX structure with an energy absorption structure and a child safety seat. The ISOFIX structure with the energy absorption structure comprises a base support assembly, an energy absorption piece and an ISOFIX assembly. According to the child safety seat, when the child safety seat is subjected to great external force in a test / accident, the ISOFIX assembly is stressed and pulled out outwards, and at the moment, the force of the ISOFIX assembly is transmitted to the energy absorption piece. When the external force reaches a set value, the energy absorption piece deforms and collapses. By means of the characteristic that a large amount of energy can be absorbed in the material deformation and collapse process of the energy absorption piece, the child safety seat is greatly buffered, so that the acceleration borne by a passenger on the child safety seat does not exceed a limit value, and the safety of the passenger is effectively protected.

Description

Technical Field

[0001] The utility model relates to an ISOFIX structure with an energy-absorbing structure and a child safety seat. Background Art

[0002] ISOFIX (International Standards Organization FIX) is an internationally standardized child safety seat installation system. Developed by the United Nations Economic Commission for Europe (UNECE), it aims to simplify the installation process and improve the safety of child safety seats through standardized fixing points. The ISOFIX system mainly includes the following parts:

[0003] ISOFIX anchor points: These are dedicated fixing points on the vehicle's seats, usually located between the backrest and the seat cushion of the vehicle's rear seat. They are rigid connection points that are designed to connect directly to the ISOFIX connectors on the child safety seat.

[0004] ISOFIX connectors: These are the parts on a child safety seat, usually located at the base of the seat. The connectors are designed to plug into the ISOFIX anchor points on the vehicle and lock into place.

[0005] The main advantages of the ISOFIX system include:

[0006] Simplified installation: Standardized fixing points make the installation process more intuitive and simple, reducing the risk of incorrect installation.

[0007] Improved safety: The ISOFIX system improves child safety in the vehicle by reducing the seat's movement in the vehicle.

[0008] Versatility: The ISOFIX system has been widely recognized and implemented worldwide, allowing child safety seats to be easily transferred between different vehicles.

[0009] However, the connection between the ISOFIX component and the base component on existing child safety seats is a rigid connection. When the child safety seat is subjected to a large acceleration impact, such as in testing or a car accident, this rigid connection cannot absorb the energy. Utility Model Content

[0010] The technical problem to be solved by the present invention is to overcome the defects in the prior art and provide an ISOFIX structure and a child safety seat with an energy absorbing structure.

Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0046] like Figure 1-Figure 3 As shown, this embodiment discloses an ISOFIX structure with an energy absorbing structure, which includes a base bracket assembly 1, an energy absorbing member 4 and an ISOFIX assembly 3.

[0047] The base bracket assembly 1 includes a tunnel portion 11 and a base 12. The tunnel portion 11 is a rectangular shell with a channel arranged inside the shell. The base 12 is also rectangular in shape and is provided with a mounting groove with an opening facing the channel of the tunnel portion 11. The mounting groove and the channel extend in the same direction and are coaxially arranged with the channel.

[0048] The energy absorbing member 4 is fixedly arranged in the installation groove.

[0049] One end of the ISOFIX assembly 3 is connected to the energy absorbing member 4, and the other end extends forward after passing through the channel.

[0050] In this embodiment, when the child safety seat is subjected to significant external forces during testing or an accident, the ISOFIX assembly 3 is pulled outward, transferring its force to the energy absorber 4. When the external force reaches a set value, the energy absorber 4 deforms and breaks. By utilizing the energy-absorbing properties of the energy absorber 4 during deformation and breakage, it provides a significant cushioning effect on the child safety seat, preventing the occupant from experiencing acceleration exceeding the specified limit, thereby effectively protecting the occupant.

[0051] Furthermore, in this embodiment, by connecting one end of the ISOFIX component 3 to the energy-absorbing member 4 and passing the other end through the channel and connecting it to the side wall of the tunnel portion 11, effective force transmission is ensured when subjected to external force, and a precise force transmission path can be achieved. The base bracket assembly 1 includes a channel in the tunnel portion 11 and a mounting groove in the base 12, which makes the installation of the ISOFIX component 3 more stable, while ensuring a coaxial connection with the energy-absorbing member 4, thereby improving the stability of the overall structure. The energy-absorbing member 4 is fixedly arranged in the mounting groove. Such a layout enables the energy-absorbing member 4 to more effectively absorb and disperse impact force when subjected to external force. Through the coaxially arranged mounting groove and channel, and the fixed arrangement of the energy-absorbing member 4, the entire ISOFIX structure becomes more compact, reducing space occupancy, and improving the integration of the structure.

[0052] More specifically, the base 12 is provided with an elongated hole 121 extending in the same direction as the mounting slot. A connecting hole 31 corresponding to the elongated hole 121 is provided at the location where the ISOFIX assembly 3 connects to the energy absorber 4. The energy-absorbing ISOFIX structure of this embodiment also includes a first connecting member 2, which is a rod-shaped connecting member such as a rivet. The first connecting member 2 passes through the connecting hole 31 and then the elongated hole 121 to connect to the energy absorber 4.

[0053] In this embodiment, the design of the first connector 2 allows it to pass through the connection hole 31 and then the elongated hole 121 to connect with the energy absorber 4. This design simplifies the assembly process, making the ISOFIX structure more convenient and quick to install, and enhances the connection stability. Furthermore, the extension direction of the elongated hole 121 is the same as the extension direction of the mounting slot and the extension direction of the ISOFIX assembly 3, providing a precise force transmission path. When subjected to external force, the force of the ISOFIX assembly 3 can be accurately and efficiently transmitted to the energy absorber 4 along the extension direction of these three directions.

[0054] Furthermore, the ISOFIX structure with an energy-absorbing structure of this embodiment also includes a second connecting member 5, which is also a rod-shaped connecting member such as a rivet, which passes through the through hole 122 to connect the first end 42 of the energy-absorbing member 4 and the base 12, and the first connecting member 2 connects the second end 41 of the energy-absorbing member 4 and the ISOFIX assembly 3.

[0055] In this embodiment, the second connector 5 connects the first end 42 of the energy absorber 4 to the base 12, while the first connector 2 connects the second end 41 of the energy absorber 4 to the ISOFIX assembly 3. This design enhances the stability of the entire structure. This two-end connection allows the energy absorber 4 to deform and collapse more effectively when subjected to extreme external forces, thereby absorbing more energy and improving energy absorption efficiency.

[0056] More specifically, in this embodiment, the first end 42 is an end of the energy absorbing member 4 close to the tunnel portion 11 , and the second end 41 is an end of the energy absorbing member 4 facing away from the tunnel portion 11 .

[0057] In this embodiment, the above-described structure enables the energy absorber 4 to be squeezed and deformed and collapsed when subjected to extreme external forces. Compared to the pull-and-crush deformation and collapse of the energy absorber 4, the squeeze-and-deformation design allows the energy absorber 4 to respond to external forces in multiple directions, resulting in more efficient deformation. This multi-directional response allows the energy absorber 4 to absorb more energy, improving overall energy absorption efficiency and thus enhancing the safety of the child safety seat during collisions or testing.

[0058] Specifically, the energy absorber 4 in this embodiment is made of metal, polymer, or ceramic materials, preferably aluminum. Aluminum absorbs and disperses energy through plastic deformation during impact, reducing the impact on the child passenger. Different materials have varying physical properties, such as strength, toughness, weight, and cost, allowing for selection of the appropriate material based on specific application needs and performance requirements.

[0059] This embodiment also discloses a child safety seat, which includes the aforementioned ISOFIX structure with an energy-absorbing structure.
