Description

Technical Field

[0001] This invention relates to the field of child safety seats, and in particular to a child safety seat with adaptive energy absorption for side impact protection. Background Technology

[0002] Statistics show that in 2020, side-impact collisions accounted for approximately 41.8% of all traffic accidents involving motor vehicles in my country, far exceeding the proportion of frontal and rear-end collisions. The fatality rate for occupants in side-impact accidents also exceeded 35%. Furthermore, structurally, the C-pillar is significantly weaker than the B and A-pillars; in terms of safety equipment, side airbags are typically only installed in the front seats. Therefore, second-row occupants face a higher risk of injury or death in side-impact accidents. Since child safety seats are located in the second row, children face an even higher risk of injury or death in side-impact accidents.

[0003] Existing child safety seats use plastic or foam energy-absorbing structures on the sides of the backrest, but their energy absorption effect is limited. In severe side collisions, these protruding energy-absorbing structures can transfer excess impact energy to the child in contact with the backrest. Furthermore, existing child safety seats are fixed in the lateral direction. In side collisions with significant vehicle body deformation and intrusion, the deformed and intruded vehicle body compresses the child safety seat, and the laterally fixed child safety seat will further deform and compress the child, encroaching on the child occupant's survival space.

[0004] The current national standard GB27887, "Child Restraint Systems for Motor Vehicles," assesses the frontal and rear-end collision protection performance of car child safety seats. This means that most domestic car child safety seat products primarily focus on frontal and rear-end collision protection. However, a revised version of GB27887 is forthcoming, and the European ECE R129 regulation includes requirements for CRS (Contrast Reduction System) side impact protection at speeds of 23-26 km / h. Real-world traffic accidents are often more diverse, with many side impact accidents exceeding 26 km / h. Existing child safety seats are designed only to meet regulatory requirements, offering limited protection against side impacts and failing to meet practical needs, thus posing a risk of inadequate safety for children in these seats. Summary of the Invention

[0005] This invention addresses the problems existing in the prior art by devising an adaptive energy-absorbing child seat for side impact protection. In side impact accidents with large vehicle body deformation and intrusion, when the impacted and deformed vehicle body compresses the side of the child safety seat, the lateral force transmission bracket undergoes lateral sliding as the energy-absorbing sheet deforms. The more energy the energy-absorbing sheet deforms and absorbs, the greater the lateral sliding distance, thus increasing the survival space for the child occupant.

[0006] The technical solution adopted to achieve the present invention is: a side-impact protection adaptive energy-absorbing child seat, comprising: a seat body 11 and a base 12, characterized in that it further comprises: a side-impact anti-collision beam 13, a lateral force transmission connecting bracket 14, a sliding energy-absorbing component 15, a riveted slider 16, and a lower base frame 17, wherein a sliding energy-absorbing component 15 is disposed between two identical and oppositely disposed lower base frames 17, and an energy-absorbing component positioning groove 173 is disposed on the inner side of the lower base frame 17, wherein both ends of the sliding energy-absorbing component 15 are respectively engaged with the energy-absorbing component positioning groove 173, and two... A riveted slider 16 is fixedly connected to the lower frame 17 of the base. Two sets of slider groove brackets 141 are provided on the lateral force transmission connecting bracket 14. Slider grooves 142 are provided on the slider groove brackets 141. The riveted slider 16 is engaged with the slider grooves 142 and is riveted to the slider grooves 142 by rivets. A collision-resistant crossbeam fastening sleeve 144 is provided at the right end of the lateral force transmission connecting bracket 14. Two identical sets of lateral force transmission connecting brackets 14 are fixedly connected to the side collision-resistant beam 13 by the collision-resistant crossbeam fastening sleeve 144. The base 12 is fixedly connected to the lateral force transmission connecting bracket 14.

[0007] Furthermore, a sliding groove 151 is provided on the sliding energy absorption assembly 15, and an energy absorption sheet 152 is provided in the sliding groove 151.

[0008] Furthermore, a slider groove 161 is provided on the riveting slider 16, and a riveting positioning hole 162 is provided on the upper surface of the riveting slider 16.

[0009] Furthermore, the lower frame 17 of the base includes: a frame body 171, an ISOFIX interface 172, and an energy-absorbing component positioning groove 173. Two sets of energy-absorbing component positioning grooves 173 are provided on the inner side of the frame body 171, and the energy-absorbing component positioning grooves 173 are fixedly connected to the frame body 171. An ISOFIX interface 172 is provided on the outer side of the frame body 171, and the ISOFIX interface 172 is connected to an ISOFIX.

[0010] Furthermore, an error usage reminder system is provided on the base 12. The error usage reminder system includes: a power supply, a controller, a door detection sensor, a communication monitoring module, and a prompting module. The controller is electrically connected to the power supply, the door detection sensor is electrically connected to the power supply, the communication monitoring module is electrically connected to the power supply, and the prompting module is electrically connected to the power supply.

[0011] The beneficial effects of the side-impact protection adaptive energy-absorbing child seat of the present invention are reflected in:

[0012] 1. A side-impact adaptive energy-absorbing child seat, which uses a side-impact anti-collision beam and force transmission bracket to transfer the impact force to a sliding energy-absorbing device in the child seat base, causing the child seat to slide laterally and absorb the side impact energy, increasing the survival space for the child occupant. In addition, its misuse reminder system can identify whether the side-impact protection device is correctly installed according to the position of the child seat in the vehicle, and issue a reminder if the installation is incorrect.

[0013] 2. A side-impact adaptive energy-absorbing child seat, which uses the base as the main force transmission path for side collisions. The energy-absorbing structure of the base bears most of the side impact energy, which can effectively reduce the side impact energy received by the child safety seat back and weaken the impact on the child occupant. In side-impact accidents with large vehicle body deformation and intrusion, when the vehicle body deformed and intruded by the impact compresses the side of the child safety seat, the child safety seat base can make the child safety seat slide laterally into the vehicle. The sliding distance is affected by the impact energy, which avoids the child safety seat squeezing the child and increases the child occupant's survival space in side-impact accidents.
