Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model effective energy-absorbing bumper/spoiler is described in further detail.
As shown in FIG. 1 to 3, the utility model effective energy-absorbing bumper/spoiler, comprise bumper body 19 and be arranged on the energy-absorption box 20 of bumper body 19 both sides, energy-absorption box 20 comprises: the outer crumple pipe 17 of octagon of hollow, be provided with outside crumple pipe 17 outside many with the crumple groove 18 of the axis perpendicular of outer crumple pipe 17, and crumple groove 18 is arranged and the staggered layout of uniform intervals in stratiform.Octagonal outer crumple pipe 17 is wherein higher relative to traditional form strength, better energy can be absorbed when being subject to clashing into, and crumple groove 18 can play the effect strengthening outer crumple pipe 17 intensity, the effect guiding outer crumple pipe 17 crumple direction when being impacted can be played again.
Buffer structure is mounted in the inside of outer crumple pipe 17, and buffer structure comprises: two spaced housings 1, form pinch off channel 2 between two housings 1.The radius stay 15 of locating support is arranged in pinch off channel 2.Compressing shell 3 is arranged on housing 1, and the limit chamber 4 compressing shell 3 is communicated with pinch off channel 2, and compression shell 3 is inclined design, is provided with and compresses round pin 5 in limit chamber 4.When the impulsive force that the stressed plate 16 of locating support is clashed into time, radius stay 15 can be with mobile in pinch off channel 2.In the process of movement, radius stay 15 will contact with the compression round pin 5 of both sides and drive and compress round pin 5 movement in limit chamber 4 together.Because compression shell 3 is inclined design, in the moving process compressing round pin 5, compress the application force that round pin 5 can be subject to compressing shell 3, make it more near radius stay 15, namely make the application force between compression round pin 5 and radius stay 15 strengthen, to stop radius stay 15 to move, play the effect of buffering.
Further, when impulsive force strengthens further, when compressing round pin 5 and moving to the top of limit chamber 4, the position-limiting unit in an actor's rendering of an operatic tune 6 can be touched.Concrete, compress the top that round pin 5 can turn to pressing plate 13, stressed the moving inward of touch pole 7 drives dwang 8 to rotate around rotating shaft 9, and then induced effect bar 10 again, baffle plate 11 is deviate from epitrochoidal chamber 12, is pressed in the outside of radius stay 15, play further limiting buffer effect.
In addition, be also provided with outside touch pole 7 and recover spring 14, after radius stay 15 shifts out pinch off channel 2, positioning unit is resetted.
The octagonal outer crumple pipe of the utility model effective energy-absorbing bumper/spoiler is higher relative to traditional form strength, better energy can be absorbed when being subject to clashing into, and crumple groove can play the effect strengthening outer crumple pipe intensity, the effect guiding outer crumple pipe crumple direction when being impacted can be played again.In addition, when the impulsive force that stressed plate is clashed into time, radius stay can be with to move in pinch off channel.In the process of movement, radius stay will contact with the compression round pin of both sides and drive and compress round pin and move in limit chamber together.Because compression shell is inclined design, in the moving process compressing round pin, compress the application force that round pin can be subject to compressing shell, make it more near radius stay, namely make the application force between compression round pin and radius stay strengthen, to stop radius stay to move, play the effect of buffering.Further, when impulsive force strengthens further, when compressing round pin and moving to the top of limit chamber, position-limiting unit can be touched.Concrete, compress the top that round pin can turn to pressing plate, stressed the moving inward of touch pole drives dwang around axis of rotation, and then induced effect bar again, baffle plate is deviate from epitrochoidal chamber, is pressed in the outside of radius stay, play further limiting buffer effect.In addition, outside described touch pole, be also provided with recovery spring, after radius stay shifts out pinch off channel, positioning unit resetted.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
