The invention relates to a composite seat energy absorption structure for vehicles. The composite seat energy absorption structure comprises a seat back, a seat cushion and a buffer and energy absorption structure. The bottom ends of two sides of the seat back are mounted to the rear ends on two sides of the seat cushion respectively through connecting plates, a front mounting support and a rear mounting support are arranged on the lower sides of each connecting plate, and each front mounting support is hinged to the seat cushion. The composite seat energy absorption structure is characterized in that the buffer and energy absorption structure comprises C-shaped buffer plate structures and buffer and energy absorption material layers, wherein each C-shaped buffer plate structure is mounted between each rear mounting support and the seat cushion, and the buffer and energy absorption material layers are arranged on the back of the seat back and the bottom of the seat cushion. Each C-shaped buffer plate structure comprises a C-shaped buffer plate and a limiting plate, one endpoint of each C-shaped buffer plate is hinged to the the rear mounting support of the corresponding connecting plate while the other endpoint is hinged to the seat cushion, a positioning hole and a limiting slot are formed in each limiting plate, one endpoint of each C-shaped buffer plate is hinged to the positioning hole of the corresponding limiting pate while the other endpoint is moveably mounted in the corresponding limiting slot, the positioning holes are round holes, the limiting slots are oblong holes, and the circle center of each positioning hole is located on the center line of the corresponding limiting slot.

The invention provides a central-through-sunken-part-reinforced front longitudinal beam. The central-through-sunken-part-reinforced front longitudinal beam comprises a main side plate and a sunken side plate. A closed cavity is defined by the main side plate and the sunken side plate, a central sunken groove is formed in the sunken side plate, and the sinking direction of the central sunken groove faces the main side plate. The central-through-sunken-part-reinforced front longitudinal beam has the advantages that as the central-sunken-groove cross section design is adopted, the problem that a deformation form of a front longitudinal beam with a traditional cross section is instable is effectively solved; as the cross section form of the front longitudinal beam is changed, under the conditions of the same material and the same mass, the safe collision energy-absorption requirement of the front longitudinal beam is effectively met, the crushing force and the energy absorption index are effectively increased, and the light-weight requirement of a car body is met.

The invention discloses an intelligent falling protection patch and a protection method thereof, the protection patch is pasted on clothes and trousers of the part, needing to be protected, of a user, and when the user falls down and the part with the falling intelligent protection patch is in contact with the ground, through energy absorption and buffering of a cushioning energy absorption layer and an elastic buffering layer; corresponding joint parts of a user is protected from injury, meanwhile, a gravity sensor and a gyroscope are used for monitoring the acceleration and the body position change when the human body falls down respectively and transmitting the acceleration and the body position change to a CPU, and a communication module is controlled to send falling-down information for intelligent alarm.

The invention discloses an vehicle anti-collision beam capable of increasing the collision protection area and a using method thereof. The vehicle anti-collision beam comprises a main body assembly and a protection mechanism, and the main body assembly comprises a front anti-collision beam, an energy absorption box body, an vehicle frame, a guide column and a sleeve; the protection mechanism comprises a T-shaped shaft rod, an arc-shaped baffle, a shell, a T-shaped sliding groove, a first spring and a second spring. The T-shaped shaft rod drives the first spring to be compressed under the action of impact force, so that the T-shaped shaft rod slides in the T-shaped sliding groove, the arc-shaped baffle is popped out of the front anti-collision beam, the protection area of the front anti-collision beam is increased through the popped-out arc-shaped baffle, the anti-collision effect is improved, the attractiveness of a vehicle is not affected, and when a violent impact accident occurs, the front anti-collision beam drives a supporting block to move, the moving supporting block breaks an acrylic plate body to extrude a liquid storage bag, so that the flame-retardant liquid stored in the liquid storage bag is sprayed out, the vehicle is prevented from being ignited, and the protection effect on the vehicle is further improved.

The invention relates to the field of child safety seat, in particular to a child seat with a ring unlocker and a headrest. Springs for damping are added in a base, a backrest, the headrest and the like of the child safety seat so as to facilitate cushioning and energy absorption during collision, and bodily injury to children due to collision is reduced. Meanwhile, an FIX unlocking component, a footrest component and a safety belt component of the seat are optimized to supply practicability; an anti-splashing component is added to avoid injury to children due to splashing materials during collision.
