Infant bidirectional basket type safety seat with easy-unlocking lock machine

Abstract

The invention relates to an infant bidirectional basket type safety seat with an easy-unlocking lock machine. The infant bidirectional basket type safety seat comprises a base assembly and a basket assembly. The basket assembly comprises a left side plate and a right side plate which are fixedly connected through a fixing shaft. A seat plate is installed between the left side plate and the right side plate. The head and the tail of the seat plate are connected with an upper sliding shaft and a lower sliding shaft correspondingly in a penetrating mode. The upper sliding shaft and the lower sliding shaft are connected with kidney-shaped grooves in the left side plate and the right side plate correspondingly in a penetrating mode. The two ends of the upper sliding shaft and the lower sliding shaft are each connected with a spring rocker mechanism. The base assembly comprises a base pipe frame assembly and an energy absorption assembly. Various impact conditions are considered, bidirectional buffering are conducted, through buffering energy absorption of a spring, buffering distance is increased, the impact peak value of impact is reduced, thus children can be protected overall and effectively, and injury is reduced.

Description

technical field [0001] The invention relates to a child safety seat, in particular to a baby 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 at different speeds. When accidental accidents of these vehicles collide, the occupants will be in a mechanical shock load environment, and various tissues of the human body will produce corresponding biomechanical responses under the action of inertial force and contact force. Once the human tissue exceeds the recoverable limit, it will lead to the destruction of chemical tissue or the damage, decay or loss of normal physiological function, which will cause permanent damage, such as fracture, tendon and ligament rupture, organ rupture, bruising and bleeding, and brain damage. Concussion causes intracranial hemorrhage, fainting, nervous system bl...

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
