Description

"Energy absorbing system"
The present invention relates to an impact absorbing system, preferably for use in a vehicle, which is provided with an impact absorbing member. The impact absorbing member is formed as a hollow profile with apertures in the walls and shearing bolts fixing the impact absorbing member to the side frame of a vehicle.
It is known from the applicant's own patent EP 1 079 992 B1 to use shear bolts in an impact absorbing member to fix the member to the surrounding structure. During an impact situation the bolts will perform a controlled shearing in the member, thereby absorbing energy.
The impact absorbing member provided with shearing bolts only support one force level thereby providing a limited flexibility in the crash protection design. As it is not possible to control the system with external parameters, the system will remain passive relating to different crash situations.
The focus in crash design has until now been on protecting the vehicle or passengers in the vehicle. However, there has been an increasing focus on protecting the environment around the vehicle and especially pedestrians.
The crash design can be divided into different speed regimes. In a crash where a vehicle has a speed from 0 to 20 km/h the task of the impact absorbing structure of the vehicle is to protect the vehicle from deformation beyond the front transversal beam and crash box as it is presumed that neither the passengers inside the vehicle nor an outside pedestrian have a high risk of being injured. This can be obtained by most of the currently designed impact absorbing members being situated in the front area of the vehicle.
When the speed of the vehicle is above approximately 50 km/h, the focus of the crash design is on protecting the passengers in the vehicle. The side frames and frame structure is designed to maintain the compartment undeformed by deforming the front and/or rear part of the vehicle. The increasing use of air bags is a part of the passenger protecting system.
Most accidents involving pedestrian injury happen when vehicles have a speed between 20 and 50 km/h. Different designs to improve the pedestrian protection during an impact has been investigated. For example is the use of external air bags described in DE 199 35 342 A1. Extra displaceable fender parts are described in GB 2 321 624. As there is a limited space inside the vehicle structure these systems present solutions which are likely not to be compact enough for the narrow spaces in the vehicle structure.
The object of the present invention is to provide an impact absorbing system which provide a sufficient impact absorbing ability at low speeds and which is sufficiently flexible to render pedestrians protection during a crash situation.
Another object of the invention is to present an impact absorbing system which is compact and therefore do not need extra space to work sufficiently. It is also an object of the present invention to present a reliable system with a small quantity of active parts.
This is done by constructing an impact absorbing system comprising an impact absorbing member provided with shearing bolts and active bolts which are entered into or released by means of a signal as the speed exceeds or goes below a predefined speed.
The invention will now be described in detail by means of figures, where Fig. 1 shows an impact absorbing member installed in a vehicle, Fig. 2 shows a detail of the impact absorbing system, Fig. 3 shows an actuator.
The vehicle can be a car, bus, train or any other vehicle provided with an energy absorbing system. The vehicle in the present example is a car having a side frame structure and a cross member or bumper and where an impact absorbing member is situated in connection with these structures.
Fig. 1 shows an impact absorbing member or crash box 1 situated between a cross member or bumper beam 2 and a frame member 3 of a vehicle. Bolts 4 are fixing the crash box 1 to the bumper beam 2.
Shearing bolts 5 are fixing the crash box 1 to an actuator 6 mounted on the side frame 3 of the vehicle. At least one shearing bolt 5 (see also Fig. 2) are led through shear lines or shear apertures 7 in at least one wall 8 of the crash box 1. Even if two shearing bolts 5 are used in the present example, it can be suitable to use only one or more than two bolts in a different impact absorbing system. Each shearing bolt 5 is lead through a corresponding shear aperture 7 in at least one of the walls 8 of the crash box. In the present example it is used two shearing bolts 5 which pass through two opposing walls 8 of the crash box 1. Only one of the opposing walls is shown on Fig. 1.
Fig. 2 shows a more detailed part of the impact absorbing system. The energy absorbing member or crash box 1 of the present example is formed as a hollow profile having a rectangular cross section. The energy absorbing member can however have any other cross section within the scope of the invention. A hollow profile may also be filled with an energy absorbing product such as aluminium foam. The crash box of the present invention is further made of extruded aluminium but other materials such as steel or composites can be used if this is found suitable as explained above. Shear apertures 7 are made in opposing walls 8 of the crash box 1. The crash box according to the present invention has two apertures 7 in each wall. In the present crash box 1 , the shear apertures 7 of opposing walls 8 have a corresponding profile. A person skilled in the art will understand that the shear apertures can have any other suitable profile which gives the intended performance of the impact absorbing system.
The width of the shear apertures made in the walls is designed to communicate during a crash. The shear apertures 7 in the present example are adapted to the shearing bolts 5. The shear apertures have a first section where the width of the aperture is corresponding with the cross section of the shearing bolt 5. However, it should be understood that the first section may have an narrower profile than the cross section of the shearing bolt 5 thereby causing some resistance when the shearing bolt 5 is moved through the energy absorbing member or crash box 1.
A second section of the shearing aperture 7 is cut narrower than the first section. When the shearing bolts 5 are forced through the crash box 1 , the first section of the shear aperture 7 will cause a low degree of resistance as the shearing bolts 5 are easily led through the shear apertures 7. When led into the second section of the shear apertures 7, the bolts will start shearing, thereby absorbing energy.
Active apertures 7' are designed to hold at least one active bolt 9. In the present example, four active bolts 9 are arranged in the actuator 6 where two bolts are corresponding with each of two opposing walls 8' of the crash box.
The actuator 6 will receive input signals which triggers a mechanism which enters the active bolts into or releases them from the actuator side walls. The signal can be trigged by anything that indicates danger of pedestrian impact such as the speed range, a radar system for early sensing of pedestrian impact or any other suitable system for detecting pedestrian impact before it actually happens.
The active apertures 7' has an inverse design compared to the shear apertures 7. The first section of the active apertures is narrow thereby forcing the active bolts 9 to shear the walls 8' of the crash box. A second section of the active apertures 7' has a width corresponding to the cross section of the active bolts 9, thereby allowing the bolts to pass in the second section of the active apertures 7" during a crash situation.
The apertures are corresponding in such a manner that the narrow first sections of the active apertures 7' are ending where the second narrow section of the shear apertures 7 are starting.
The material properties of the crash box and the desigη of the apertures plays an important role when defining the amount of the force being absorbed by the impact absorbing system. It is obvious that a person skilled in the art can choose a different design of the apertures within the scope of the invention. The apertures can for example be cut with a constant narrowing or augmenting with, a web of material can be left in at least a part of at least one of the apertures or at least one of the apertures can be completely cut open.
The actuator 6 of the present example is designed to surround the crash box 1 end section, see Figs. 2 and 3. Holes 10 are made in two opposing webs 11 on the actuator 6. The active bolts 9 are situated in two opposing side walls 8' placed perpendicular to the webs 11.
The shearing bolts 5 are lead through the holes 10 in a first web 11 of the actuator 6 further through the shear apertures 7 in the crash box 1 and thereafter through the corresponding holes 9 in a second web 11. The bolts can thereafter be fixed with nuts 13. Perpendicular to the shearing bolts 5, a set of active bolts 9 are led through the active apertures 71 in the walls 8' of the crash box. The active bolts 10 are advanced into the active apertures 7' in the walls 8' when the vehicle is standing still. After starting the vehicle the actuator 6 can be controlled by the speed of the vehicle. As the speed exceeds a predefined speed, the active bolts 9 will retract into the side walls 12 of the actuator, thereby lowering the amount of material being sheared in a crash situation. The active bolts 9 can be activated by an electro mechanical, electro hydraulic or any other relevant system.
Fig. 3 shows the actuator 6 with the active bolts in the two different positions. The active bolts 9 will only perform a shearing operation at low speeds, thereby providing a stiff impact absorbing system which is able to absorb the necessary amount of energy to protect the inner structure of the vehicle. At speeds above a predefined level which suitably can be around 20 km/h, the active bolts will retract into the side walls. This gives an impact absorbing system which will yield improved protection to any object being hit by the vehicle.
