Abstract
The utility model discloses an air bag type bumper which comprises a closed air bag type bumper casing, wherein a sealed pressure cavity is formed in the closed air bag type bumper casing; and a safe snuffle valve is mounted on the closed air bag type bumper casing. In case of a traffic accident, when the bumper suffers a collision, the air bag type bumper casing absorbs energy generated by the collision and deforms, so that the air pressure in the pressure cavity rises; when the air pressure in the pressure cavity is higher than the high pressure threshold value of the safe snuffle valve, the safe snuffle valve is opened, so that part of the air in the pressure cavity is drained out and the air pressure in the pressure cavity is reduced; and when the air pressure in the pressure cavity is lower than the low pressure threshold value of the safe snuffle valve, the safe snuffle valve is closed, and the bumper can buffer sequential impacts and be free from the phenomenon of cracking.
Description
Technical field
The utility model relates to a kind of bumper/spoiler, relates in particular to a kind of air sac bumper/spoiler.
Background technology
At present; be used for the method for automobile collision preventing with protection driver and passenger's safety; at the front-end and back-end of automobile dress metal or plastic housing bumper/spoiler; though can the absorption portion energy when colliding; but come endergonic because it is metal or the plastic deformation that leans against bumper/spoiler when colliding; so it is less to absorb energy, does not often have the crashproof effect of automobile when fair speed.Energy absorbing power when increasing bumper impact, bumper/spoiler is designed to the air bag form, during bump, rely on the gas compression in the air sac bumper/spoiler to absorb Impact energy, though having solved the traditional insurance thick stick, such bumper/spoiler absorbs the little problem of Impact energy, but the energy that such bumper/spoiler absorbs also is limited, when the energy that absorbs is too much, the phenomenon of explosion appears in air sac bumper/spoiler easily, cause catastrophic explosion, air sac bumper/spoiler after the explosion can't be repaired, and use cost is higher relatively.
The utility model content
Technical problem to be solved in the utility model provides a kind of air sac bumper/spoiler, and it not only can absorb energy in a large number in knockout process, can also the high pressure in the air sac bumper/spoiler be reduced pressure automatically, prevents the bumper/spoiler explosion.
For solving the problems of the technologies described above, the technical solution of the utility model is: the air sac bumper/spoiler, comprise osed top air sac bumper/spoiler housing, and have the leak free pressure chamber in the described housing, on the described housing safety valve is installed.
As a kind of optimized technical scheme, described housing comprises the assembly wall that is installed on the automobile and bears wall away from the bump of described assembly wall that described safety valve is installed on the described assembly wall.
As a kind of optimized technical scheme, described housing comprises the assembly wall that is installed on the automobile and bears wall away from the bump of described assembly wall that described aie escape valve is installed in described assembly wall and described bump bears on the connecting wall of wall.
As a kind of optimized technical scheme, described safety valve is unidirectional by pass valve.
Owing to adopted technique scheme, the air sac bumper/spoiler comprises osed top air sac bumper/spoiler housing, has the leak free pressure chamber in the described housing, on the described housing safety valve is installed; Traffic accident takes place, when bumper/spoiler is clashed into, air sac bumper/spoiler housing absorbs the energy that bump produces, deformation takes place, pressure rises in the pressure chamber, when the pressure chamber internal gas pressure was higher than the HVT high voltage threshold of safety valve, safety valve was opened, gas in the pressure chamber is partly discharged, and the pressure chamber internal gas pressure reduces; When the air pressure in the pressure chamber was lower than the low pressure threshold of safety valve, safety valve was closed, and bumper/spoiler can cushion ensuing impact and the explosion phenomenon can not occur.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: the 1-housing; The 2-pressure chamber; The 3-assembly wall; The 4-bump bears wall; The 5-safety valve.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only some one exemplary embodiment of the present utility model has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
As shown in drawings, the air sac bumper/spoiler, comprise osed top air sac bumper/spoiler housing 1, has leak free pressure chamber 2 in the described housing 1, described housing 1 comprises the assembly wall 3 that is installed on the automobile and bears wall 4 away from the bump of described assembly wall 3 that on the described assembly wall 3 of described housing 1 safety valve 5 is installed, described safety valve 5 is unidirectional by pass valve, described safety valve 5 can be not destroyed in knockout process away from the bump bearing surface of bumper/spoiler.
As another kind of embodiment, described safety valve 5 is installed in described assembly wall 3 and described bump bears on the connecting wall of wall 4; Because when bump, the pressure that this wall bears relatively bump to bear the pressure that wall 4 bears little, can play the effect of protection safety valve 5.
Principle of work: traffic accident takes place, when bumper/spoiler was clashed into, air sac bumper/spoiler housing 1 absorbed the energy that bump produces, and deformation takes place, pressure rises in the pressure chamber 2, when pressure chamber 2 internal gas pressures were higher than the HVT high voltage threshold of safety valve 5, safety valve 5 was opened, and the gas in the pressure chamber 2 is partly discharged, leakage by gas consumes the part impact again, reduction impact by a larger margin, the both sides' that collided with protection safety, pressure chamber 2 internal gas pressures reduce; When the air pressure in the pressure chamber 2 was lower than the low pressure threshold of safety valve 5, safety valve 5 was closed, and bumper/spoiler can cushion ensuing impact and the explosion phenomenon can not occur.
Certainly, the pressure chamber 2 in the air sac bumper/spoiler housing 1 also can be divided into two or more a plurality of annular seal space, and corresponding each annular seal space is provided with a safety valve 5.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
