Description
Technical field
The utility model relates to safe escape device, particularly a kind of vehicle escape hammer.
Background technology
The vehicle such as automobile, train when presence of fire, traffic accident, urban waterlogging etc. in emergency circumstances, using life-saving hamer to smash glass for vehicle window is that actv. is saved oneself means.Present public transport means is all equipped with the hammer pounding glass, but occurs that somebody does not know how to use in use, not knowing to beat glass where could by the problem of glass crushing; And need very large strength could by glass crushing, for child old man, limited in one's abilityly could not to escape smoothly; Such escaping tool is not equipped with for private savings automobile, by car owner control oneself buy after put onboard, may occur can't find the situation of life-saving hamer when using, be difficult to the active demand meeting emergency escape.
Utility model content
The purpose of this utility model is overcome weak point of the prior art and provide easy to use, and the accurate and effective Glass breadks easily position of knocking of energy, smashes glass for vehicle window, successfully escape, and leicht fallen D/A, the vehicle escape hammer that child adult can use.
The purpose of this utility model is realized by following approach.
Vehicle escape hammer, comprise elasticity and launch component and the broken glass ball of rigidity, broken glass ball is arranged at elasticity and launches on component, and elasticity is launched component fixed end and is fixed on vehicle window one frame, other frame is provided with a socket and launches eye-splice on component movable end for inserted elastic.
When the broken glass ball of rigidity is pulled out outward, when then decontroling, under the elastic force effect that elasticity launches component, produce impulsive force and broken glass ball is hit to glass.As catapult, steel ball is launched away, shattered glass.When the impulsive force (f) that the steel ball that launches out produces is greater than the static weight (p) that glass for vehicle window bears, steel ball gets final product shattered glass.
The utility model preferred version: elasticity is launched component fixed end and is bolted on frame, fixed end and socket are arranged on the adjacent frame of glass vehicle window respectively, and elasticity launches component oblique pull in glass vehicle window corner place.
Because glass for vehicle window corner area is less, little to the diffusion area of power, be more easily crashed to pieces.Glass for vehicle window is smashed so life-saving hamer is pounded the position of corner is easier than the hit heart.Therefore, life-saving hamer oblique pull is arranged near glass for vehicle window corner place.
Like this, elasticity is launched component fixed end and is fixed on frame, when not using at ordinary times, movable end is not fixed, and broken glass ball is in free laying state, swings to prevent broken glass ball, the position can launching the eye-splice of component movable end in elasticity arranges a bandage, fixing broken glass ball; Another frame is provided with a socket, when running into emergency case, when needing brokenly window, directly eye-splice is extracted out from bandage, inserts in socket and fastens.Elasticity is launched component and is in the state of being stretched, and adjusts broken glass ball position in Glass breadks easily position.Can shattered glass effectively.
The utility model can be optimized for further: described elasticity is launched component fixed end and is fixed on the adjacent frame of distance glass port lower frame 120 height, and socket is fixed on lower frame 120 millimeters place, and the broken glass ball of rigidity is arranged at elasticity and launches component mid point.
Like this, after socket is inserted in eye-splice, elasticity is launched component and is stretched, broken glass ball is positioned at elasticity and launches component point midway, and the vertical distance of its center to two frame is 50 millimeters, is in the most frangible position of glass, namely complete location once inserting, ten parts quick, for escape gains time.
It is elastic rubber band that described elasticity launches component, the perforation of rigidity Sui Bo ball center is through elastic rubber band, and the broken glass ball of rigidity is diameter more than 5 millimeters steel balls, or more than 12 millimeters steel balls, or more than 18 millimeters steel balls, the glass for vehicle window being configured at 3 millimeters, 5 millimeters and 7 mm of thickness respectively uses.
Automobile window glass thickness (h) is generally 3 to 7 millimeters, and sizeable steel ball can shattered glass when the impulsive force (f) that elastic rubber band launches out is greater than the static weight (p) that glass for vehicle window bears.
That is: f>p
F=mv1/t, p=90h2r (wherein, m is steel ball quality, and v1 is the speed before steel ball passes glass, and t is the time of steel ball and glass effect, and 90MP is case hardened glass skin stress, and h is thickness of glass, and r is steel ball radius)
Wherein, v is the speed that steel ball passes glass to t=h/v()
M=4/3 π r
3ρ (wherein, ρ is steel ball density)
4/3πr
3·ρ·v1·v>90h
2·2r
The speed (v) of the steel ball that rubber band is got is generally 60-90m/s, now gets 60m/s,
So hypothesis steel ball is 60m/s through the speed V1 before glass, be 10m/s through speed V2 after glass, then, average velociity is 35m/s, and steel ball is 40m/s through the speed V of glass,
Then;
1, when thickness of glass h is 3 millimeters,
r
2>90×0.003
2×2/（4/3×3.14×7.852×60×40），
R>1.41 millimeter,
3 millimeters are greater than for solid steel ball diameter.
Now, steel ball impulsive force f=mv1/t=4/3*3.14*0.0015
3* 7.852*60*40/0.003=88.6 kilogram, the static weight p=90h2r=90*3*2*0.0015=81 kilogram of 3 millimeters of glass, impulsive force is greater than glass static weight, can by glass crushing.
Extend there through because steel ball center needs perforation to be used for elastic rubber band, so consider the safety factor adding 1.5 times, steel ball size should be and is greater than 5 millimeters.
So broken glass ball diameter is more than 5 millimeters steel balls, 3 millimeters of glasss for vehicle window can be smashed.
2, when thickness of glass h is 5 millimeters,
r
2>90×0.005
2×2/（4/3×3.14×7.852×60×40），
r>4mm，
Now, steel ball impulsive force f=mv1/t=4/3*3.14*0.004
3* 7.852*60*40/0.005=1009 kilogram, the static weight p=90h2r=90*5*2*4=360 kilogram of 5 millimeters of glass, impulsive force is greater than glass static weight, can by glass crushing.
Extend there through because steel ball central hole is used for elastic rubber band, so consider the safety factor adding 1.5 times, steel ball size should be and is greater than 12 millimeters.
So broken glass ball diameter is more than 12 millimeters steel balls, 5 millimeters of glasss for vehicle window can be smashed.
3, when thickness of glass h is 7 millimeters,
r
2>90×0.007
2×2/（4/3×3.14×7.852×60×40），
R>6 millimeter,
Now, steel ball impulsive force f=mv1/t=4/3*3.14*0.006
3* 7.852*60*40/0.007=2434 kilogram, the static weight p=90h2r=90*7*2*6=756 kilogram of 7 millimeters of glass, impulsive force exceeds greatly glass static weight, just can by glass crushing by very little power.
Extend there through because steel ball central hole is used for elastic rubber band, so consider the safety factor adding 1.5 times, steel ball size should be and is greater than 18 millimeters.
So broken glass ball diameter is more than 18 millimeters steel balls, 7 millimeters of glasss for vehicle window can be smashed.
Adopt elastic rubber band that thickness is different to obtain stronger impulsive force for the steel ball that varies in size.
It can also be spring that described elasticity launches component, and the broken glass ball of rigidity is fixed on spring mid point.
The utility model also can be optimized for further: the surface of rigidity broken glass ball has pointed projection.
Like this, greatly strengthen destructive force, glass for vehicle window is more easily smashed.
In sum, the utility model has the following advantages than prior art tool: structure is simple, uses quick, accurate positioning, just glass for vehicle window can be smashed, reach the effect of getting twice the result with half the effort by very little strength.Child old man can use, and meets the demand that escape is urgent.
