Infant bidirectional basket type safety seat provided with spring rocker arm mechanism

Abstract

The invention relates to a two-way baby basket type safety seat with a spring rocker mechanism, which includes a base assembly and a basket assembly. The basket assembly includes left and right side panels, which are fixedly connected by fixed shafts, and A seat plate is installed between the side plates, and the head and tail of the seat plate are connected with upper and lower shafts respectively. Both ends of the shaft are connected with a spring rocker mechanism; the base assembly includes a base pipe frame assembly and an energy-absorbing assembly, considering various collision situations, two-way buffering is done, and energy is absorbed through the buffering of the spring , and increase the buffer distance to reduce the impact peak of the collision, which can comprehensively and effectively protect children and reduce injuries.

Description

technical field [0001] The invention relates to a child safety seat, in particular to an infant two-way basket type safety seat. Background technique [0002] The progress and development of human civilization and science and technology have enabled us to have a variety of vehicles for different purposes, operating in different fields in different ways and speeds. When these vehicles collide by accident, the occupants will be in a mechanical shock load environment, and various parts of the human body will have corresponding biomechanical responses under the action of inertial force and contact force. Once human tissue exceeds the recoverable limit, it will lead to the destruction of tissue or normal physiological functions, decay or loss, resulting in permanent damage, such as fractures, tendon and ligament ruptures, organ ruptures, bruising and bleeding, and brain damage. Concussion causes intracranial hemorrhage, fainting, or blockage or blockage of the nervous system, wh...

[0006] 3. Child safety seat front body protection safety protection technology: child safety front body protection technology: this technology uses a large-area blocking displacement method, so that the impact force of the human body acts on a large-area cushion to reduce unit pressure and head displacement It can act on the buffer pad of the device to play the role of head buffer to prevent cervical spine and cervical muscles and ligaments from being damaged. However, this method makes the human chest and abdomen bear force but is not good for the organs, and because there is no upward force constraint, the human body is moved from the front Accidents caused by jumping out from body restraints

This protection device can protect the life of the driver and occupant within the relative speed range, but it cannot protect the occupant from injury. When the inertial force of the human body is bound to the limit by the seat belt, the huge inertial force may cause fractures of the clavicle, sternum, and scapula. Once the airbag is opened, its speed can reach 300Km / h, which will have a great impact on the human head. Although it is not fatal, its biological reaction will also bring different degrees of harm to people, such as concussion, fainting or even intracranial hemorrhage.

[0009] Based on the above-mentioned existing safety protection device technology, its technical feature is to limit the displacement of personnel to prevent direct collision between the human body and the vehicle components, and to use cushioning materials to absorb the impact energy, and to play a certain protective role within a certain speed range. range, coupled with individual differences, cannot guarantee occupant safety
