Lifting basket type safety seat with splash prevention function

Abstract

The invention relates to a lifting basket type safety seat with a splash prevention function. The lifting basket type safety seat with the splash prevention function comprises a base assembly and a lifting basket assembly, wherein the lifting basket assembly comprises a left side board and a right side board which are fixedly connected through a fixing shaft; a seat board is installed between the left side board and the right side board; an upper sliding shaft and a lower sliding shaft are connected to the head portion and the tail portion of the seat board in a penetrating mode correspondingly; the upper sliding shaft and the lower sliding shaft are connected to kidney-shaped grooves of the left side board and the right side board in a penetrating mode correspondingly; the two ends of the upper sliding shaft and the two ends the lower sliding shaft are connected with spring rocker arm mechanisms correspondingly; and the base assembly comprises a base pipe frame assembly and an energy absorption assembly. Various collision situations are considered, bidirectional buffering design is made, the impact peak of collision is reduced through buffering energy absorption of springs and increasing of the buffering distance, children can be protected comprehensively and effectively, and injury is reduced.

Description

Technical field [0001] The invention relates to a child safety seat, in particular to a two-way basket-carrying safety seat for infants. 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 accidentally collide, the occupants will be in a mechanical shock load environment. Under the action of inertial force and contact force, various tissues of the human body will produce corresponding biomechanical responses. Once the human tissue exceeds the recoverable limit, it will cause the destruction of the destructive tissues or the damage to normal physiological functions, decay or loss, which will cause permanent damage, such as fractures, rupture of tendons and ligaments, rupture of organs, bruises and bleeding, and brain Concussion causes intracranial hemorrhage, fainting, obstruct...

Problems solved by technology

[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
