一种智能调节式动能自动泄力缓解***Intelligent adjustable kinetic energy automatic venting mitigation system 技术领域Technical field
本发明涉及交通安全技术领域，是一种全新的智能调节式动能自动泄力缓解***。The invention relates to the technical field of traffic safety, and is a brand-new intelligent adjustable kinetic energy automatic venting mitigation system.
背景技术Background technique
随着汽车工业的发展，汽车给人们的交通带来了很大的方便，但汽车在运行过程中发生碰撞时容易对司乘人员的身体造成伤害，相碰撞的汽车也容易造成严重变形，甚至报废。汽车运行过程中存在的安全问题，备受厂家和消费者高度重视。为了保护司乘人员安全，尽量减轻相碰撞汽车的变形。现有技术采用的磁控胶泥的汽车碰撞缓冲***、喷水式汽车碰撞缓冲装置、电磁式汽车碰撞缓冲装置等，达到缓冲碰撞，吸收碰撞能量的目的，但这些缓冲装置结构复杂，体积较大，改装难度大，成本较高或承载卸荷小。With the development of the automobile industry, cars bring great convenience to people's traffic.

发明内容Summary of the invention

Ventilation mitigation system.
本发明的具体技术方案是：The specific technical solution of the present invention is:
所述一种智能调节式动能自动泄力缓解***由碰撞受力杠、泄力部件、机座、智能控制***组成。The intelligent adjustable kinetic energy automatic venting mitigation system is composed of a collision force bar, a bleed force component, a machine base and an intelligent control system.
所述泄力部件万向球头连接在所述机座上，所述机座刚性连接在汽车车身上。The bleeder member universal ball joint is coupled to the base, and the base is rigidly coupled to the vehicle body.
所述泄力部件包括液压顶杆、活塞、弹簧和液压缸。The bleeder member includes a hydraulic ram, a piston, a spring, and a hydraulic cylinder.
所述碰撞受力杠刚性连接液压顶杆，所述液压顶杆上套有所述弹簧并刚性连接所述活塞。所述液压缸上连接进油管和排油管，所述进油管连接油泵与液压缸，所述进油管上设有手动复位开关连接储油罐与液压缸，所述排油管上设有泄压阀连接储油罐与液压缸。所述油管连接油泵与储油罐。The collision force bar is rigidly connected to the hydraulic ram, and the hydraulic ram is sleeved with the spring and rigidly connected to the piston. The hydraulic cylinder is connected to the oil inlet pipe and the oil discharge pipe, the oil inlet pipe is connected with the oil pump and the hydraulic cylinder, and the oil inlet pipe is provided with a manual reset switch connected to the oil storage tank and the hydraulic cylinder, and the oil discharge pipe is provided with a pressure relief valve Connect the oil storage tank to the hydraulic cylinder. The oil pipe connects the oil pump and the oil storage tank.
所述智能控制***通过设有汽车运行速度v与液压缸内压力p的特定关系，控制油泵和泄压阀。所述特定关系根据能量守恒定律Q＝E+W确定，其中汽车碰撞所产生的能量Q＝1/2mΔv2，弹簧被压缩吸收的能量E＝1/2kl1 2(与弹簧弹性模量k和压缩量l1有关)，液压缸被压缩吸收的能量W＝1/2π(D/2)2pl2(D为活塞底面直径，l2为活塞移动距离，p为液压缸内压力)。The intelligent control system controls the oil pump and the pressure relief valve by providing a specific relationship between the running speed v of the automobile and the pressure p in the hydraulic cylinder. The specific relationship is determined according to the energy conservation law Q=E+W, wherein the energy generated by the collision of the automobile is Q=1/2mΔv 2 , and the energy absorbed by the spring is E=1/2kl 1 2 (with the spring elastic modulus k and The compression amount l 1 is related to), the energy absorbed by the hydraulic cylinder is W=1/2π(D/2) 2 pl 2 (D is the diameter of the piston bottom surface, l 2 is the piston moving distance, and p is the hydraulic cylinder pressure).
在动量守恒的情况下，汽车正常运行时，智能控制***根据汽车运行速度v自动控制液压缸内压力p。当汽车加速时，智能控制***控制油泵工作，增大液压缸内压力p，使液压缸内压力p与汽车运行速度v符合上述特定关系。当汽车减速时，智能控制***控制油泵停止工作并自动打开泄压阀，减小液压缸内压力p，使液压缸内压力p与汽车运行速度v符合上述特定关系。In the case of momentum conservation, the intelligent control system automatically controls the pressure p in the hydraulic cylinder according to the running speed v of the vehicle during normal operation of the vehicle. When the car accelerates, the intelligent control system controls the operation of the oil pump, and increases the pressure p in the hydraulic cylinder so that the pressure p in the hydraulic cylinder and the running speed v of the vehicle conform to the above specific relationship. When the car decelerates, the intelligent control system controls the oil pump to stop working and automatically opens the pressure relief valve to reduce the pressure p in the hydraulic cylinder, so that the pressure p in the hydraulic cylinder and the running speed v of the vehicle meet the above specific relationship.
汽车发生碰撞时，运行速度v发生突变，智能控制***自动切换至自身保护电路，使液压缸内压力p保持不变。这时碰撞力作用于碰撞受力杠，碰撞受力杠带动与之刚性连接的液压顶杆，推动活塞压缩液压缸和弹簧，吸收部分能量。当液压缸内压力p达到最大安全压力值时，智能控制***自动打开泄压阀，通过排油管排出液压油，释放部分能量，当液压缸内压力p接近最小安全压力值时，智能控制***自动关闭泄压阀，继续推动活塞压缩弹簧和液 压缸，吸收能量，不断循环往复，最终碰撞所产生的能量全部被弹簧和液压缸缓释，有效延长汽车碰撞缓冲时间Δt，减小作用于司乘人员和汽车车身的碰撞力F，将司乘人员受到的伤害和汽车变形降到最低。When the car collides, the running speed v changes suddenly, and the intelligent control system automatically switches to its own protection circuit, so that the pressure p in the hydraulic cylinder remains unchanged. At this time, the collision force acts on the collision force bar, and the collision force bar drives the hydraulic ram which is rigidly connected with the force bar, and pushes the piston to compress the hydraulic cylinder and the spring to absorb part of the energy. When the pressure p in the hydraulic cylinder reaches the maximum safe pressure value, the intelligent control system automatically opens the pressure relief valve, discharges the hydraulic oil through the oil discharge pipe, and releases part of the energy. When the pressure p in the hydraulic cylinder approaches the minimum safety pressure value, the intelligent control system automatically Close the pressure relief valve and continue to push the piston compression spring and fluid The pressure cylinder absorbs energy and continuously circulates and reciprocates. The energy generated by the final collision is all released by the spring and the hydraulic cylinder, effectively prolonging the collision time Δt of the vehicle and reducing the collision force F acting on the driver and the vehicle body. The injuries suffered by the passengers and the car deformation are minimized.
液压缸所吸收的能量逐步释放后，弹簧依然处于被压缩状态，液压缸内处于负压状态，液压缸内的负压状态对弹簧的释放具有一定的阻碍作用。利用弹簧组合液压缸形式的泄力部件具有良好的缓冲作用，可避免弹簧反弹对人体造成二次伤害。After the energy absorbed by the hydraulic cylinder is gradually released, the spring is still in a compressed state, and the hydraulic cylinder is in a negative pressure state, and the negative pressure state in the hydraulic cylinder has a certain hindrance to the release of the spring. The bleeder part in the form of a spring combined hydraulic cylinder has a good cushioning effect, which can prevent the spring rebound from causing secondary damage to the human body.
碰撞后，手动打开手动复位开关，在弹簧弹力的作用下，液压油通过进油管进入液压缸，弹簧缓慢恢复到初始状态，释放所吸收的能量。After the collision, the manual reset switch is manually turned on. Under the action of the spring force, the hydraulic oil enters the hydraulic cylinder through the oil inlet pipe, and the spring slowly returns to the initial state, releasing the absorbed energy.
另因其泄力部件可绕机座轴线在360度方向上偏转，在液压顶杆和活塞的引导作用下，能自动迎合非垂直于液压顶杆和活塞的碰撞力，始终保持液压顶杆和活塞垂直于液压缸，从而泄掉来自垂直或非垂直于液压顶杆和活塞的碰撞力，达到自动缓解和泄掉碰撞力，吸收汽车碰撞能量的作用。In addition, because the bleeder member can be deflected in the 360-degree direction around the axis of the machine seat, under the guidance of the hydraulic ram and the piston, it can automatically meet the collision force of the non-perpendicular hydraulic ram and the piston, and always maintain the hydraulic ram and The piston is perpendicular to the hydraulic cylinder, thereby escaping the collision force from the vertical or non-perpendicular to the hydraulic ram and the piston, achieving automatic relief and escaping the collision force, absorbing the collision energy of the vehicle.
综上所述，本发明具有结构简单、性能可靠，体积较小、受力载荷大、可组合安装在汽车较容易发生碰撞的前、后、左、右各部位，起到保护司乘人员安全和减轻汽车变形的目的。In summary, the invention has the advantages of simple structure, reliable performance, small volume, large force load, and can be combined and installed in front, rear, left and right parts where the automobile is more likely to collide, thereby protecting the safety of the passengers. And to alleviate the purpose of car deformation.

所述一种智能调节式动能自动泄力缓解***由碰撞受力杠1、泄力部件6、机座9、智能控制***11组成。The intelligent adjustable kinetic energy automatic venting mitigation system is composed of a collision force bar 1, a venting member 6, a base 9, and an intelligent control system 11.
所述泄力部件6万向球头连接在所述机座9上，所述机座9刚性连接在汽车车身10上。The bleeder member 6 is connected to the frame 9 at a ball joint, and the frame 9 is rigidly coupled to the vehicle body 10.
所述泄力部件6包括液压顶杆2、活塞4、弹簧3和液压缸5。The bleeder member 6 includes a hydraulic ram 2, a piston 4, a spring 3, and a hydraulic cylinder 5.
所述碰撞受力杠1刚性连接液压顶杆2，所述液压顶杆2上套有所述弹簧3并刚性连接所述活塞4。所述液压缸5上连接进油管7和排油管14，所述进油管7-1连接油泵8与液压缸5，所述进油管7-2上设有手动复位开关16连接储油罐15与液压缸5，所述排油管14上设有泄压阀13连接储油罐15与液压缸5。所述油管12连接油泵8与储油罐15。The collision force bar 1 is rigidly connected to the hydraulic ram 2, and the hydraulic ram 2 is sleeved with the spring 3 and rigidly connected to the piston 4. The hydraulic cylinder 5 is connected to the oil inlet pipe 7 and the oil discharge pipe 14, and the oil inlet pipe 7-1 is connected with the oil pump 8 and the hydraulic cylinder 5, and the oil inlet pipe 7-2 is provided with a manual reset switch 16 connected to the oil storage tank 15 and The hydraulic cylinder 5 is provided with a pressure relief valve 13 connected to the oil storage tank 15 and the hydraulic cylinder 5. The oil pipe 12 connects the oil pump 8 and the oil storage tank 15.
所述智能控制***11通过设有汽车运行速度v与液压缸5内压力p的特定关系，控制油泵8和泄压阀13。所述特定关系根据能量守恒定律Q＝E+W确定，其中汽车碰撞所产生的能量Q＝1/2mΔv2，弹簧3被压缩吸收的能量E＝1/2kl1 2(与弹簧弹性模量k和压缩量l1有关)，液压缸5被压缩吸收的能量W＝1/2π(D/2)2pl2(D为活塞底面直径，l2为活塞移动距离，p为液压缸内压力)。The intelligent control system 11 controls the oil pump 8 and the pressure relief valve 13 by providing a specific relationship between the vehicle operating speed v and the pressure p in the hydraulic cylinder 5. The specific relationship is determined according to the energy conservation law Q=E+W, wherein the energy generated by the collision of the automobile is Q=1/2mΔv 2 , and the energy absorbed by the spring 3 is E=1/2kl 1 2 (with the spring elastic modulus k Related to the compression amount l 1 ), the energy absorbed by the hydraulic cylinder 5 is W = 1/2π(D/2) 2 pl 2 (D is the diameter of the piston bottom surface, l 2 is the piston moving distance, and p is the hydraulic cylinder pressure) .
本发明依据的原理是动量守恒定律(m1v1+m2v2＝m1v1，+m2v2，)和动量与冲量转换关系(mΔv＝FΔt)。The principles of the present invention is based on the law of conservation of momentum (m 1 v 1 + m 2 v 2 = m 1 v 1, + m 2 v 2,) , and the impulse momentum conversion relationship (mΔv = FΔt).
在动量守恒的情况下，汽车正常运行时，智能控制***11根据汽车运行速度v自动控制液压缸5内压力p。当汽车加速时，智能控制***11控制油泵8工作，增大液压缸5内压力 p，使液压缸5内压力p与汽车运行速度v符合上述特定关系。当汽车减速时，智能控制***11控制油泵8停止工作并自动打开泄压阀13，减小液压缸5内压力p，使液压缸5内压力p与汽车运行速度v符合上述特定关系。In the case of momentum conservation, the intelligent control system 11 automatically controls the pressure p in the hydraulic cylinder 5 in accordance with the vehicle operating speed v when the vehicle is in normal operation. When the car accelerates, the intelligent control system 11 controls the operation of the oil pump 8 to increase the pressure in the hydraulic cylinder 5 p, the pressure p in the hydraulic cylinder 5 is made to conform to the above specific relationship with the running speed v of the vehicle. When the car decelerates, the intelligent control system 11 controls the oil pump 8 to stop working and automatically opens the pressure relief valve 13, reducing the pressure p in the hydraulic cylinder 5, so that the pressure p in the hydraulic cylinder 5 and the vehicle operating speed v conform to the above specific relationship.
汽车发生碰撞时，运行速度v发生突变，智能控制***11自动切换至自身保护电路，使液压缸5内压力p保持不变。这时碰撞力作用于碰撞受力杠1，碰撞受力杠1带动与之刚性连接的液压顶杆2，推动活塞4压缩液压缸5和弹簧3，吸收部分能量。当液压缸5内压力p达到最大安全压力值时，智能控制***11自动打开泄压阀13，通过排油管14排出液压油，释放部分能量，当液压缸5内压力p接近最小安全压力值时，智能控制***11自动关闭泄压阀13，继续推动活塞4压缩弹簧3和液压缸5吸收能量，不断循环往复，最终碰撞所产生的能量全部被弹簧3和液压缸5缓释，有效延长汽车碰撞缓冲时间Δt，减小作用于司乘人员和汽车车身10的碰撞力F，将司乘人员受到的伤害和汽车变形降到最低。When the vehicle collides, the running speed v is abrupt, and the intelligent control system 11 automatically switches to its own protection circuit, so that the pressure p in the hydraulic cylinder 5 remains unchanged. At this time, the collision force acts on the impact force bar 1, and the collision force bar 1 drives the hydraulic ram 2 rigidly connected thereto, and the push piston 4 compresses the hydraulic cylinder 5 and the spring 3 to absorb part of the energy. When the pressure p in the hydraulic cylinder 5 reaches the maximum safe pressure value, the intelligent control system 11 automatically opens the pressure relief valve 13 and discharges the hydraulic oil through the oil discharge pipe 14 to release part of the energy. When the pressure p in the hydraulic cylinder 5 approaches the minimum safe pressure value. The intelligent control system 11 automatically closes the pressure relief valve 13 and continues to push the piston 4 to compress the spring 3 and the hydraulic cylinder 5 to absorb energy, and continuously circulates and reciprocates, and the energy generated by the final collision is all released by the spring 3 and the hydraulic cylinder 5, thereby effectively extending the automobile. The collision buffering time Δt reduces the impact force F acting on the driver and the vehicle body 10, and minimizes the damage suffered by the driver and the car deformation.
液压缸5所吸收的能量逐步释放后，弹簧3依然处于被压缩状态，液压缸5内处于负压状态，液压缸5内的负压状态对弹簧3的释放具有一定的阻碍作用。利用弹簧3组合液压缸5形式的泄力部件6具有良好的缓冲作用，可避免弹簧3反弹对人体造成二次伤害。After the energy absorbed by the hydraulic cylinder 5 is gradually released, the spring 3 is still in a compressed state, and the hydraulic cylinder 5 is in a negative pressure state, and the negative pressure state in the hydraulic cylinder 5 has a certain hindrance to the release of the spring 3. The bleeder member 6 in the form of a combination of the spring 3 and the hydraulic cylinder 5 has a good cushioning effect, and can prevent the spring 3 from rebounding and causing secondary damage to the human body.
碰撞后，手动打开手动复位开关16，在弹簧3弹力的作用下，液压油通过进油管7-2进入液压缸5，弹簧3缓慢恢复到初始状态，释放所吸收的能量。After the collision, the manual reset switch 16 is manually turned on, and under the action of the spring 3 elastic force, the hydraulic oil enters the hydraulic cylinder 5 through the oil inlet pipe 7-2, and the spring 3 slowly returns to the initial state, releasing the absorbed energy.
另因其泄力部件6可绕机座9轴线在360度方向上偏转，在液压顶杆2和活塞4的引导作用下，能自动迎合非垂直于液压顶杆2和活塞4的碰撞力，始终保持液压顶杆2和活塞4垂直于液压缸5，从而泄掉来自垂直或非垂直于液压顶杆2和活塞4的碰撞力，达到自动缓解和泄掉碰撞力，吸收汽车碰撞能量的作用。In addition, since the bleeder member 6 can be deflected in the 360-degree direction around the axis of the base 9, under the guiding action of the hydraulic ram 2 and the piston 4, the collision force non-perpendicular to the hydraulic ram 2 and the piston 4 can be automatically catered for, The hydraulic ram 2 and the piston 4 are always kept perpendicular to the hydraulic cylinder 5, thereby escaping the collision force from the vertical or non-perpendicular to the hydraulic ram 2 and the piston 4, thereby automatically mitigating and escaping the collision force and absorbing the collision energy of the automobile. .
