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.

[0011] The utility model solves the above technical problems through the following technical solutions:

[0012] An ISOFIX structure with an energy-absorbing structure, comprising:

[0013] A base support assembly includes a tunnel portion and a base, wherein the tunnel portion is provided with a passage extending along a first direction, and the base is provided with a first connecting hole;

[0014] The ISOFIX assembly is provided with a plurality of slots distributed along a first direction and a second connection hole, wherein the second connection hole is located on a side of the slots most outer in the first direction and closer to the tunnel portion, and one end of the ISOFIX assembly extends through the tunnel along the first direction;

[0015] A connecting piece is inserted into the first connecting hole and the second connecting hole.

[0016] An ISOFIX structure with an energy-absorbing structure, comprising:

[0017] A base support assembly includes a tunnel portion and a base, wherein the tunnel portion is provided with a channel extending along a first direction, and the base is provided with a plurality of slots distributed along the first direction and a first connection hole, wherein the first connection hole is located on a side of the tunnel portion away from the outermost slot in the first direction;

[0018] An ISOFIX component is provided with a second connection hole, and one end of the ISOFIX component passes through the channel and extends along the first direction;

[0019] A connecting piece is inserted into the first connecting hole and the second connecting hole.

[0020] In some embodiments, the connecting members are rivets or bolts.

[0021] In some embodiments, the number of the slots is three.

[0022] A child safety seat comprises the aforementioned ISOFIX structure with an energy-absorbing structure.

[0023] On the basis of conforming to the common sense in this field, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0024] The positive progressive effect of the present invention is that the ISOFIX structure of the present invention has an energy-absorbing structure, and corresponding spacer areas are formed between the multiple slots. The width and thickness of the spacer areas will collapse and be damaged when subjected to a certain force. The collapse and damage of the material will absorb a large amount of energy, reducing the acceleration experienced by the entire product. When the child safety seat is subjected to a large external force during testing / accidents, the ISOFIX assembly is pulled outward by the force. At this time, the force of the ISOFIX assembly is transmitted to the base bracket assembly through the connector. When the external force reaches the set value, the spacer area collapses and is damaged. By utilizing the characteristics of the material that can absorb a large amount of energy during deformation and collapse, the child safety seat is given a large buffer, so that the acceleration experienced by the occupant in the child safety seat does not exceed the limit value, thereby effectively protecting the safety of the occupant.

[0040] Example 1

[0041] like Figure 1-Figure 3 As shown, this embodiment discloses an ISOFIX structure with an energy-absorbing structure, which includes a base bracket assembly 11 , an ISOFIX assembly 3 and a connector 2 .

[0042] The base bracket assembly 1 includes a tunnel portion 11 and a base 12. The tunnel portion 11 is provided with a channel extending along a first direction. A first connection hole 4 is provided on the base 12 at a position connected to the ISOFIX component 3. In this embodiment, the tunnel portion 11 and the base 12 are both rectangular sleeve-shaped, but are not limited to this.

[0043] The ISOFIX assembly 3 is provided with a plurality of slots 6 and a second connection hole 5 distributed along the first direction at a position corresponding to the base 12. The second connection hole 5 is located on the side of the slot 6 most outward in the first direction close to the tunnel portion 11 ( Figure 1-Figure 3 Furthermore, the spacing between the second connection hole 5 and the rightmost slot 6 is almost the same as the spacing between the slots 6. One end of the ISOFIX assembly 3 extends along the first direction through the channel.

[0044] The connecting member 2 is inserted into the first connecting hole 4 and the second connecting hole 5 to connect the base 12 and the ISOFIX assembly 3 .

[0045] In this embodiment, the above-mentioned structural form is adopted, and corresponding spacer areas 31 are formed between the multiple slots 6. The width and thickness of this spacer area 31 will collapse and be damaged when subjected to a certain force. The collapse and damage of the material will absorb a large amount of energy, reducing the acceleration experienced by the entire product. When the child safety seat is subjected to a large external force during testing / accident, the ISOFIX component 3 is pulled outward by the force. At this time, the force of the ISOFIX component 3 is transmitted to the base bracket component 1 through the connector 2. When the external force reaches the set value, the spacer area 31 collapses and is damaged. By utilizing the characteristics of the material that can absorb a large amount of energy during deformation and collapse, a large buffer is provided to the child safety seat, so that the acceleration experienced by the occupant in the child safety seat does not exceed the limit value, thereby effectively protecting the safety of the occupant.

[0046] Furthermore, in this embodiment, the connecting member 2 is a rivet or a bolt, and the number of the slots 6 is 3. However, in other embodiments, the present invention is not limited thereto.

[0047] Example 2

[0048] The ISOFIX structure with energy-absorbing structure of this embodiment is different from that of embodiment 1 in that:

[0049] The slots 6 are formed on the base 12 of the base support assembly 1. Specifically, the base 12 is provided with a plurality of slots 6 distributed along a first direction and a first connection hole 4. The first connection hole 4 is located on a side away from the tunnel portion 11 and away from the outermost slot 6 in the first direction.

[0050] A second connection hole 5 is defined on the ISOFIX component 3 at a position corresponding to the first connection hole 4 on the base 12 , and one end of the ISOFIX component 3 extends along the first direction through the channel.

[0051] The connecting member 2 is inserted into the first connecting hole 4 and the second connecting hole 5 to connect the base 12 and the ISOFIX assembly 3 .

[0052] Other aspects are the same as those of Example 1.

[0053] In this embodiment, the above-mentioned structural form is adopted, and corresponding spacer areas 31 are formed between the multiple slots 6. The width and thickness of this spacer area 31 will collapse and be damaged when subjected to a certain force. The collapse and damage of the material will absorb a large amount of energy, reducing the acceleration experienced by the entire product. When the child safety seat is subjected to a large external force during testing / accident, the ISOFIX component 3 is pulled outward by the force. At this time, the force of the ISOFIX component 3 is transmitted to the base bracket component 1 through the connector 2. When the external force reaches the set value, the spacer area 31 collapses and is damaged. By utilizing the characteristics of the material that can absorb a large amount of energy during deformation and collapse, a large buffer is provided to the child safety seat, so that the acceleration experienced by the occupant in the child safety seat does not exceed the limit value, thereby effectively protecting the safety of the occupant.
