Definitions
- the present invention relates to a PP material door panel energy absorber which is provided in vehicle doors and which enables to absorb the force in the event of an impact (collision) acting on the door and to attenuate the force acting on the door.
- the vehicle door energy absorbing systems in the state of the art are placed between the panels that form the inner and outer surfaces of the vehicle doors.
- the energy absorbing systems are formed by ridges which are connected to each other. Multiple ridges connected onto each other move together in the event of any collision force and ensure that the coming force acts on the door with minimum intensity.
- EPP Exanded Polypropylene Foam
- EPP Energy absorbing Polypropylene Foam
- EPP Extra Polypropylene Foam
- the EPP material which is used in the state of the art vehicle door energy absorbing systems of EPP (Expanded Polypropylene Foam) material including consecutive ridges, is a very expensive material and furthermore sufficient rigidity cannot be attained at the connection points of its flexible structure and sufficient efficiency cannot be achieved in energy absorbing. Additionally, design of the consecutive ridges which work in connection with each other is difficult and formation of the ridges, which are produced in different sizes for different areas of the door, as connected to each other cannot be realized; and this problem negatively affects the vehicle door energy absorbing systems in terms of production difficulty and cost increase.
- United States patent document no. US7708313B2 discloses a system which absorbs the impact forces acting on the door during vehicle accidents by means of the ridges and grooves provided thereon.
- the system is comprised of a surface and grooves that are formed in an order. In the event of an impact, the grooves of the door bracket move against the force together as they are located near each other.
- An objective of the present invention is to provide a PP material door panel energy absorber by which impact forces that may act on the vehicle door are absorbed and any damage in the event of an impact to the door is minimized.
- Figure 1 is a top view of the PP material door panel energy absorber of the present invention.
- Figure 2. is a top perspective view of the PP material door panel energy absorber of the present invention.
- Figure 3 is a bottom perspective view of the PP material door panel energy absorber of the present invention.
- Figure 4. is a side view of the mounting of the PP material door panel energy absorber of the present invention.
- the energy absorber (1) which is provided in vehicle doors and which enables to absorb the force in the event of an impact acting on the door and to attenuate the force acting on the door, basically comprises
- At least one first absorber (3) which extends from the base surface (2) towards the door panel and forms a ridge having a hollow inner part on the base surface (2), enables to absorb the forces coming onto the door by means of its stretching feature, and has a corrugated structure on the base surface (2),
- At least one upper hole (33) which is located at the part of the first absorber (3) that extends towards the door panel (K) and enables to increase the stretching ability of the first absorber (3) when the impact force comes, at least one second absorber (4) which is in the form of a ridge having the same features with the first absorber (3) on the base surface (2) and has different corrugation directions in order to reach from the base surface (2) to the desired places on the door panel (K).
- the energy absorber (1) of the present invention comprises a base surface (2) positioned on the panel sheet metal (P); a first absorber (3) which is provided on the base surface (2) as a ridge and includes a discharge channel (31), a connection hole (32), and upper hole (33); at least one second absorber (4) which is located on the base surface (2) together with the first absorber (3) and has the same features as the first absorber (3).
- the force acts on the energy absorber (1) over the door panel (K), and the first absorber (3) and the second absorber (4) provided on the energy absorber (1) stretch and enable to absorb all or a part of the force.
- (1) of the present invention are provided in the form of ridges on the base surface
- the inner part of the ridge that is formed is hollow so as to enable stretching.
- the first absorber (3) and the second absorber (4) to absorb the energy.
- the first absorber (3) and the second absorber (4) ridges having flexible structures stretch from the door panel towards the base surface (2) and absorb the force.
- the first absorber (3) and the second absorber (4) 111!!! from the base surface (2) towards the door panel (K).
- the base surface (2) can be provided in different sizes and the first absorber (3) and the second absorbers (4) can reach any desired point on the base surface
- the energy absorber (1) of the present invention is connected onto the panel sheet metal (P) via the base surface (2) and is fixed to the door panel (K) by means of the connection hole (32) provided on the first absorber (3). This way, it forms a more rigid structure against the coming force.
- the boss parts provided on the door panel (K) for connection fit into the connection holes located on the first absorber (3) and the second absorber (4), and upon applying heat on the boss parts, the boss parts change form and spread on the connection hole (32) and thus the first absorber (3) and the second absorber (4) are fixed on the door panel (K).
- the energy absorber (1) is produced from polypropylene material. Thanks to the fact that the energy absorber (1) is made of polypropylene material, stretching feature of the first absorber (3) and the second absorber (4) at the connection points where they are connected to the base surface (2) is reduced and thus, the first absorber (3) and the second absorber (4) are enabled to absorb more force.
- the energy absorber (1) is produced from polypropylene material, sufficient flexibility and sufficient strength balance is established and the forces resulting from the impact/collision are enabled to be absorbed.
- the first absorber (3) forms an S-shaped ridge on the base surface (2). By means of the S-shape, the forces coming onto the energy absorber (1) act on the first absorber (3) at more locations. Furthermore, thanks to the S-shape, the first absorber (3) can reach the desired areas on the base surface (2) and can receive the forces coming from different areas of the door.
- the second absorber (4) forms a corrugated ridge around the area where the first absorber (3) is located on the base surface (2).
- the said corrugated structure there is at least one ridge shaped second absorber (4) having the same features as the first absorber (3) which can reach the areas that cannot be reached by the first absorber (3), and it helps to absorb the forces coming onto the door together with the first absorber (3).
- the second absorber (4) is S shaped.
- the forces coming onto the energy absorber (1) act on the second absorber (4) at more locations.
- the second absorber (4) can reach the desired areas on the base surface (2) and can receive the forces coming from different areas of the door.
