Specific embodiment

The utility model embodiment is described further below in conjunction with the accompanying drawings：

Such as a kind of Fig. 1~Elevator safety airbag device shown in Fig. 2, including elevator 1 and car 2, car 2 is in elevator Lifting is slided in 1, further includes control module, independent current source module and gravity acceleration sensor on car 2, controls mould Block and the electrical connection of gravity acceleration sensor, module and the power supply of gravity acceleration sensor in order to control of independent current source module；The elevator Air bag device further includes the first buffer air bag 3 for being arranged on cage bottom and multiple is arranged on the of elevator bottom sidewall Two buffer air bags 4, control module control the first buffer air bag 3 and the second buffer air bag 4 to expand and shrink；Normally start in elevator When, all air bags are all in contraction state, and when elevator falls, gravity acceleration sensor sends a signal to control module, Control module controls all air bag expansions, makes car soft landing, ensures occupant safety；Second buffer air bag 4 can be along elevator Direction is uniformly distributed upwards, and the second buffer air bag 4 is uniformly distributed more upwards, higher to the safety of elevator；Above-mentioned control module can pass through The modes such as gas-accumulating tank or air pump are inflated or deflate to air bag, so as to fulfill the expansion or shrinkage of air bag.

As preference, second buffer air bag 4 is two, and corresponding setting, the both sides when car falls Buffer air bag 4 can uniform stressed, it is not easy to damaged.

As preference, 1 bottom of elevator is additionally provided with third buffer air bag 5, control module control third buffering Air bag 5 is expanded and is shunk, when elevator falls from higher position, control module control third buffer air bag expansion, elevator bottom First buffer air bag contacts dispersible impact force with third buffer air bag, and continues to slow down impact force and make the first buffer air bag more It is durable.

As preference, support plate 51 and elastic component 52 are equipped in the third buffer air bag 5,52 one end of elastic component and branch Fagging is fixedly connected, and the other end is fixedly connected with the floor of 1 bottom of elevator；When the first buffer air bag and third buffer air bag connect Continue to move to support plate after touch, elastic component 52 provides the power of a negative direction for support plate 51, and car is stopped.

As preference, the elastic component 52 is spring or rubber or high-density sponge etc..

As preference, 2 madial wall of car is equipped with protective air-bag 6, control module control protective air-bag 6 is expanded and is received Contracting, when car 2 falls, control module control protective air-bag 6 is expanded into car, prevents the body of occupant from touching sedan-chair Compartment madial wall reduces car and is injured caused by the body of occupant.

As preference, 2 inner roof wall of car is equipped with protective air-bag 6, control module control protective air-bag 6 is expanded and is received Contracting, when car 2 falls, control module control protective air-bag 6 is expanded into car, prevents the head of occupant from touching sedan-chair 2 inner roof wall of compartment reduces car 2 and is injured caused by the head of occupant.

In the present embodiment, when each car moves, gravity acceleration sensor detects whether its state belongs to fall condition, when When car 2 falls, gravity acceleration sensor sends a signal to control module, and control module controls the first buffer air bag 3, the Two buffer air bags 4, third buffer air bag 5 and protective air-bag 6 expand simultaneously, first and the second buffer air bag 4 in 2 drop event of car Contact slows down speed of falling by the second buffer air bag 4 with 2 outer surface CONTACT WITH FRICTION of car, and then the first of elevator bottom is slow Air-impulse bag 3 contacts disperses impact forces with third buffer air bag 5, continues after the first buffer air bag 3 is contacted with third buffer air bag 5 It is moved to support plate 52, and elastic component 52 is squeezed, elastic component 52 provides the power of a negative direction for support plate 51, and car is stopped Only, the protective air-bag 6 inside car 2 provides protection for the occupant in car 2, after car 2 comes to a complete stop, gravity acceleration sensor hair The number of delivering letters gives control module, and control module controls the first buffer air bag 3, the second buffer air bag 4, third buffer air bag 5 and protection Air bag 6 is slowly shunk simultaneously waits for use next time, and occupant can wait for rescue in car 2.

The advantageous effect of the present embodiment：When fracture occurs for hawser in running process of elevator or other reasons cause car 2 When falling, the second buffer air bag 4 squeezes car 2 by expansion, its speed of falling is made to slow down rapidly, the first buffer air bag 3 and the Three buffer air bags 5 disperse its impact force, finally bear remaining impact force by elastic component 5, make 2 soft landing of car, and equipped with anti- Shield air bag 6 can ensure safety of the occupant when car 2 falls；In addition, air bag is respectively provided with contraction and swelling state, it is recycled profit With having saved maintenance cost.
