The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, an embodiment of a kind of earthquake protection bed of the present invention is proposed, comprise bedrest 40 and be arranged on the bed board 10 on the bedrest 40, also include protective cover 30, drive unit 20 and shock sensor, wherein:
Above-mentioned protective cover 30 is movably arranged on above-mentioned bed board 10 times through guide rail, is processed by the hard heavy weight material that bears, and plays a protective role.
Above-mentioned drive unit 20; Be used to provide operation power; It is arranged on the above-mentioned bedrest 40, and drive unit 20 includes scalable mobile push rod 21, drives the top that above-mentioned protective cover 30 rises and covers on above-mentioned bed board 10 through the moving of this push rod 21 (stretch or contract); Protective cover 30 can cover the top of whole bed, as the barrier of protection.Above-mentioned drive unit 20 drives above-mentioned push rod 21 telescopic movings through hydraulic transmission or electromagnetic gear, or other drives moving of device realization push rod 21.
Above-mentioned shock sensor (not shown); Be arranged on the above-mentioned bedrest 40; When the vibrations of earthquake reach preset grade (operated by rotary motion reaches destructive grade), shock sensor will send instruction, starts above-mentioned drive unit 20 work and drives above-mentioned push rod 21 and move (stretch or contract).This shock sensor comprises the sensor of level or vertical direction vibrations, or other can realize detecting the device of vibrations, and above-mentioned shock sensor comprises the electric slope angle sensor of series such as LE-60-OEM, HF-20.
By the battery inversion is that high-tension electricity provides dynamic power, thereby drives the calutron that an energising back produces repulsive interaction power, promotes main driving link piston push rod 21 motions, has guaranteed the independence and the reliability of power source.Power source is if adopt hydraulic transmission, and then needing hydraulic oil pump is that hydraulic transmission provides power, and hydraulic oil pump needs power drives.When earthquake takes place, very big possibly the destruction by power equipment arranged, reliable source of power can't be provided, so hydraulic transmission and motor power reliability are not enough, should not adopt.This calutron mainly is made up of two blocks of electromagnet; After energising; Produce the power of repelling each other, when shock sensor detects a body and takes place acutely to rock, send signal and start above-mentioned drive unit 20 work through the control circuit trigger switch; Drive unit 20 moves through the stretching, extension of push rod 21 and drives the top that protective cover 30 rises and covers on bed board 10; As the barrier of protection, above-mentioned protective cover 30 and/or bedrest 40 adopts bulletproof glasses or glass-reinforced plastic material to process, and can resist in the earthquake falling object to the impact of bed body.Momentum is that the object of 50000NS (is not less than 0.04mm with protective cover 30 contacts area when pounding directly over the protective cover 30
2), the deflection of protective cover 30 is less than 10%.
Further; Above-mentioned push rod 21 is set to two and also is vertically set on respectively on the corresponding both sides of above-mentioned bedrest 40; Promptly be arranged on the side of bed, two push rods 21 correspondence respectively are arranged on two drive units 20, and corresponding both sides are provided with two push rods 21 and bed can balance be descended move; Above-mentioned push rod 21 is connected with above-mentioned bed board 10 through member in succession, and push rod 21 moves and can drive above-mentioned bed board 10 declines.10 times general who has surrendered users of bed board deliver near on the floor, to reduce the center of gravity of whole bed body, strengthen the stability of user's environment of living in, reserve adequate space simultaneously, also are that protective cover 30 is made buffering usefulness.
More specifically, the end on the above-mentioned push rod 21 is set with elevator 22, and this elevator 22 is connected with two groups of above-mentioned members in succession, this in succession member comprise Rotary Connection block 51 and bed board 10 connectors, wherein:
Above-mentioned Rotary Connection block 51; Through the center or depart from the middle part the position tie point is set; Rotary Connection block 51 can be rotatably provided on the above-mentioned bedrest 40 around this tie point; One end of this Rotary Connection block 51 and above-mentioned elevator 22 flexibly connects or flexibly connects through a connecting rod 53 and elevator 22, and driven rotary contiguous block 51 is around above-mentioned tie point rotation when being convenient to elevator 22 and moving.
Above-mentioned bed board connector 52, one of which end and above-mentioned bed board 10 are fixed or are flexibly connected through slide rail 11, and its other end is movable to be rotatably provided on the bedrest 40; This end also can rotate around bedrest 40 through screw is fixing; This end is provided with chute 521, and in above-mentioned chute 521, drive unit 20 drives push rod 21 and rises the other end of above-mentioned Rotary Connection block 51 through the movable junction button of connector; Thereby driven rotary contiguous block 51 1 ends rise; The other end descends and moves slip along chute 521, and the other end that has driven bed board connector 52 moves down, and moves down thereby drive bed board 10.
Steady for what keep bed board 10 to descend, bedrest 40 is provided with many guide pillars, is used to make bed board 10 steadily to descend along this guide pillar.But bed board 10 design bearing load: 1500Kg, 3 seconds consuming time of decline process, peak acceleration 3m/s in the process falls in dropping distance 650mm
2
Above-mentioned protective cover 30 has adopted the cover plate of two circular arcs, and two cover plates are connected together mutually and form a semi-cylindrical form structure, and semicircular structure is when bearing the power of all directions, and stress balance disperses, and can keep out the falling object of different directions.Adopt steel to make the main framework of protective cover 30, spread fiberglass then, constitute protective cover 30, adopt hand to stick with paste legal system and make fiberglass; Fiberglass is in light weight, is the weight of metal 1/4 approximately, and the requirement that just reduces power source in light weight is easy to realize its motion, and fiberglass all can compare favourably with steel on mechanical index such as plasticity and toughness, intensity.The size of one instantiation of the cover plate of two circular arcs: length 2000mm, radius 650mm, thickness 15mm, it is semicircle that the cross section of two cover plates becomes.
Above-mentioned push rod 21 is connected with two above-mentioned cover plates respectively through two groups of rocker member 60; Also can be provided with elevator 22 by above-mentioned push rod 21; Above-mentioned elevator 22 is connected with two groups of above-mentioned rocker member 60 respectively, this rocker member 60 middle parts or depart from that medium position is rotatable to be arranged on this elevator 22, and an end of rocker member 60 is connected with an above-mentioned cover plate; The other end of rocker member 60 and above-mentioned bedrest 40 flexibly connect; Be that its end points can drive elevator 22 so that above-mentioned push rod 21 stretches to move around bedrest 40 rotations, elevator 22 promotes rocker member 60 rises above-mentioned cover plate.Push rod 21 Stroke Control of drive unit 20 are within 10 centimetres, and the rise time of protective cover 30 was controlled within 3 seconds, can rise rapidly to guarantee protective cover 30.
Between two above-mentioned cover plates, be provided with locking device,, effectively prevent to be separated when weight is pressed, thereby play effective user's of protection safety when cover plate receives when two above-mentioned cover plates rise and during contact can auto lock.
