DETAILED DESCRIPTION
Fig. 1 depicts a vehicle bumper according to one embodiment.
A vehicle bumper 10A includes a rigid beam 30, being fixed to the vehicle body! and an inflatable body 28, surrounding the entire of rigid beam 30.
Fig. 2 depicts a vehicle bumper according to another embodiment.
A vehicle bumper 10B includes rigid beam 30, being fixed to the vehicle body! and a plurality of shrinkable tanks 16A, 16B, etc., each disposed at a different location of rigid beam 30, thus together surrounding thereof. Rigid beams 30 and shrinkable tanks disposed on rigid beams may surround the vehicle 360 degrees. Fig. 3 depicts a vehicle bumper according to another embodiment.
A vehicle bumper 10C includes rigid beam 30, being fixed to the vehicle body! the plurality of shrinkable tanks 16A, 16B, etc., each disposed at a different location of rigid beam 30, thus together surrounding thereof and a plurality of tubes 18A, 18B serially communicating between the shrinkable tanks.
For example, tube 18A communicates between shrinkable tanks 16A and 16B; tube 18B communicates between shrinkable tanks 16B and 16C; etc.
Fig. 4 depicts a gentle bump, being applied on the vehicle bumper of Fig. 1.
Vehicle bumper 10A upon receiving a gentle bump 50A from a bumping body 32 occupying the center only of inflatable body 28, compresses the center of inflatable body 28. The compression applied on the bumped area 60A transfers the filling substance to the non-bumped areas 60B, thus enlarging them.
Fig. 5 depicts the gentle bump of Fig. 4, being applied on the vehicle bumper of Fig. 2.
Vehicle bumper 10B upon receiving gentle bump 50A from bumping body 32 occupying the center only of rigid beam 30, being applied only on shrinkable tanks 16A, 16B and 16C only of inflatable body 28, compresses shrinkable tanks 16A, 16B and 16C only. The filling substance 26 of shrinkable tanks 16A, 16B and 16C can exit outside each, through valves of each. Namely, filling substance 26 of inflated element 16A exits through valve 20A, to the environment 62; and filling substance 26 of inflated element 16B exits through valve 20B, to the environment 62. Valves 20A, 20B, etc. may constitute sacrificial membranes. Sensors may measure pressure and temperature of substance 26, to indicate the bumping protection is proper. Fig. 6 depicts the gentle bump of Fig. 4, being applied on the vehicle bumper of Fig. 3.
Vehicle bumper 10C upon receiving gentle bump 50A from bumping body 32 occupying the center only of rigid beam 30, being applied only on shrinkable tanks 16A, 16B and 16C only of inflatable body 28, compresses shrinkable tanks 16A, 16B and 16C only.
However, in contrast to the shrinkable tanks of Fig. 5, a fraction of the filling substance 26 of each of shrinkable tanks 16A, 16B and 16C exits here to compression of the neighboring shrinkable tanks.
Namely, substance 26 of inflated element 16B exits to inflated element 16C; and since inflated element 16C is as well compressed, substance 26 thereof exits to inflated element 16D, further inflating it. In contrast to bumper 10A, a valve 20D, disposed between shrinkable tanks 16D and 16E, decreases transfer of substance 26 to inflated element 16E, thus limiting the exit of substance 26 from shrinkable tanks 16A, 16B and 16C.
Fig. 7 depicts a severe bump, being applied on the vehicle bumper of Fig. 1. Vehicle bumper 10A upon receiving a severe bump 50B from bumping body 32 occupying the center only of inflatable body 28, cannot compress the center of inflatable body 28 any more, thus breaks rigid beam 30.
Fig. 8 depicts the severe bump of Fig. 7, being applied on the vehicle bumper of Fig. 2.
Vehicle bumper 10B, upon receiving severe bump 50B from bumping body 32 occupying the center only of rigid beam 30, being applied only on shrinkable tanks 16A, 16B and 16C only of inflatable body 28, cannot compress shrinkable tanks 16A, 16B and 16C any more, thus as well breaks rigid beam
30.
Fig. 9 depicts the severe bump of Fig. 7, being applied on the vehicle bumper of Fig. 3.
Vehicle bumper 10C, upon receiving severe bump 50B from bumping body 32 occupying the center only of rigid beam 30, being applied only on shrinkable tanks 16A, 16B and 16C only of inflatable body 28, cannot compress shrinkable tanks 16A, 16B and 16C any more, thus as well breaks rigid beam 30. However, an additional fraction of the filling substance 26 of each of shrinkable tanks 16A, 16B and 16C exits here to compression of the neighboring shrinkable tanks.
Namely, substance 26 of inflated element 16B exits to inflated element 16C; and since inflated element 16C is as well compressed, substance 26 thereof exits to inflated element 16D, further inflating it! and since inflated element 16D is as well compressed, substance 26 thereof exits to inflated element 16E, further inflating it. Thus, shrinkable tanks 16D and 16E maintain elements
16A, 16B and 16C yet inflatable, thus guarding rigid beam 30.
Fig. 10 is a perspective view of part of the vehicle bumper of Fig. 3.
Vehicle bumper 10C includes rigid beam 30; and shrinkable tanks 16D, 16E, etc.; tube 18D communicating between shrinkable tanks 16D and 16E; tube 18E communicating between shrinkable tanks 16E and 16F; tube 18F communicating between inflated element 16F and the environment 62. The filling substance 26 of inflated element 16D can partly exit to inflated element 16E through tube 18D, and the exiting is limited by valve 20D; the filling substance 26 of inflated element 16E can partly exit to inflated element 16E through tube 18E, and the exiting is limited by valve 20E; the filling substance 26 of inflated element 16F can partly exit to environment 62 through tube 18F, and the exiting is limited by valve 2 OF.
Fig. 11 is a sketch of one of the valves of Fig. 10 at the closed state. Valve 20 includes a cap 56 being capped by a spring 58.
Fig. 12 is a sketch of the valve of Fig. 11 at the open state.
Upon the bumping, the pressure of filling substance 26 is stronger than spring 58, thus opening cap 56 to open state 36A, to transfer substance 26 from inflated element 16D to tube 18D.
Fig. 13 is a top view of a vehicle including vehicle bumpers of Fig. 3.
A front vehicle bumper 10C and a rear vehicle bumper 10C are fixed to the vehicle body 12.
Fig. 14 is a sectional view of the inflated element of Fig. 3, according to one embodiment.
Inflated element 16C and others may constitute a cylindrical wall 74 forming a container 68 containing filling substance 26. Cylindrical wall 74 includes thick zones 64 and thin zones 66A to 66D being spirally structured in relation to thick zones 64.
A flexible membrane 72 forms the internal side of wall
74. Fig. 15 is the inflated element of Fig. 14, upon absorbing the gentle bump of Fig. 3.
Upon receiving gentle bump 50A, the near thin zones 16A and 16B only inflate, thus releasing filling substance 26 through valve 20C to the next inflated element, being 16D in Fig. 3.
Fig. 16 is the inflated element of Fig. 14, upon absorbing the severe bump of Fig. 9.
Upon receiving severe bump 50B, all of thin zones, namely 16A, 16B, 16C and 16D inflate, thus releasing filling substance 26 through valve 20C to the next inflated element, being 16D in Fig. 9.
