Definitions
- the invention relates to a secondary transformer unit for attachment to a vehicle with electric drive according to the preamble of claim 1 and a vehicle with electric drive.
- electric motor vehicles such as hybrid cars and pure electric cars that include traction batteries for the electrical power supply of an electric motor.
- These known motor vehicles are equipped with a system for inductive power transmission, which also allows frequent recharging of the batteries with highêtkom- fort.
- This system functions like a transformer and includes a primary transformer unit mounted on the infrastructure side, for example on the rear wall of a garage, and a secondary transformer unit integrated at the front of the motor vehicle behind the front license plate.
- the document DE 10 2009 023 409 A1 relates to a system for electrical energy transmission and forms the basis for the preamble of claim 1.
- This document discloses a secondary transformer unit or secondary transformer unit, which is mounted on the bow or on the front of an electric vehicle and contains a U-shaped half-voltage core and a coil winding wound onto it at an oblique angle.
- This secondary transformer unit is mounted on the front bumper of the electric vehicle, and the front license plate of the electric vehicle is mounted on the secondary transformer unit.
- this known secondary transformer unit Since this known secondary transformer unit is attached to the bow of the vehicle, it must be integrated in an area of the vehicle which has a high influence on the crash behavior in pedestrian accidents.
- the front area of the vehicle is replaced by the additional components to be mounted, in particular the half-wave transformer, which usually consists of electrical sheets or ferrite.
- CONFIRMATION COPY core harder, but a well-defined and soft vehicle front is necessary to minimize the risk of injury to pedestrians. Since the known secondary transformer unit is mounted behind the front license plate on the front bumper, less space for deformation elements made of foam, which are arranged between the bumper and the passenger compartment, left, so that their thickness, ie their extent in the direction of travel, must be reduced. This leads to a further increase in the hardness of the vehicle front.
- the object of the invention is to improve a secondary transformer unit according to the preamble of claim 1 and a vehicle with electric drive with such a secondary transformer unit with regard to the crash behavior in pedestrian accidents.
- the invention proposes according to a first aspect, a secondary transformer unit for attachment to a vehicle with electric drive, comprising
- At least one secondary core having an upper side and a top side opposite the underside, which define the secondary core in a first direction;
- At least one secondary coil which is arranged on the secondary core; in which
- the secondary core has at least one Solldeformationsstoff extending in the first direction between the top and the bottom.
- the impact energy of the pedestrian can be derived defined.
- the thickness, that is, the extension in the direction of travel, and the shape of the foam deformation elements serving for pedestrian protection can simply be optimized in such a way as to produce the most positive possible effect in terms of crash behavior since sections of the secondary core adjacent to the desired deformation means distribute the impact forces.
- the secondary core may be formed as desired in any manner and is preferably substantially plate-shaped and has, for example, a width in a y-direction, a height in a z-direction and a thickness in an x-direction which is smaller than the width and the height.
- the x-direction corresponds to the travel or longitudinal direction of the vehicle to which the secondary transformer unit is to be attached, the y-direction of the transverse direction of this vehicle, and the z-direction of the vertical direction of this vehicle.
- the thickness is smaller than the height and the height is smaller than the width.
- the desired deformation means extend substantially in the z-direction, the legs of a pedestrian covered by the front of the vehicle, in particular, are spared.
- Such an essentially plate-shaped secondary core can easily be deformed in the event of an impact in the x-direction and requires little space between the bumper and the passenger compartment, so that the foam deformation elements to be mounted in this area, which is important for the frontal crash behavior, have a greater thickness, ie expansion in the direction of travel, can have.
- the desired deformation means can run as desired in any desired manner, for example at least partially straight and / or bent and / or angled and / or wave-shaped and / or zigzag-shaped and / or only on at least a partial distance between the upper side and the lower side.
- the desired deformation means runs from the upper side to the lower side or connects the upper side to the lower side. This course of the desired deformation means enables a particularly slight deformation of the secondary core upon impact with a substantially z-directional object, such as a leg of a pedestrian.
- the desired deformation means can be designed as desired in any desired manner and, for example, have at least one predetermined breaking line and / or at least one predetermined bending line.
- the predetermined breaking line and / or the predetermined bending line preferably has at least one perforation line and / or at least one groove.
- the perforation line and the groove cause a weakening of the material in which it is formed, so that it can break along the corresponding predetermined breaking line or be bent along the corresponding predetermined bending line.
- the desired deformation means may comprise at least one, in particular elongate, connecting element, which is softer and / or more elastic than the adjacent portions of the secondary core.
- This connecting element thus enables a relative movement, in particular a folding movement, between the adjacent sections of the secondary core, for example in the manner of a hinge. It may, if necessary, have the predetermined breaking lines and / or predetermined bending lines described above.
- the material of the connecting element can be chosen as desired as desired and preferably contains a soft magnetic material.
- the connecting element can be produced from a mixture of a plastic, such as PE or PP, or a rubber and a powdery, soft-magnetic material, for example ferrite powder, in particular by injection molding.
- the connecting element has at least one wire and / or at least one foil and / or at least one grid and / or at least one network;
- the wire and / or the film and / or the grid and / or the network is connected to the adjacent to the connecting element portions of the secondary core.
- the materials for the wire, the foil, the grid and the net can be chosen as desired and contain for example at least one metal and / or a rubber and / or at least one plastic and / or carbon and / or at least one silicone and / or at least one glass and / or at least one ceramic and / or are preferably soft magnetic.
- the desired deformation means divides the secondary core in the y-direction into sections of equal width. These sections are preferably identical, whereby the secondary core can be easily and inexpensively manufactured. It can be provided that the edges of the portions of the secondary core connected by the desired deformation means are rounded or chamfered.
- the invention proposes, according to a second aspect, an electric vehicle comprising at least one of the proposed secondary transformer units.
- one of the secondary transformer units is arranged at the front of the vehicle and / or one of the secondary transformer units at the rear of the vehicle and / or one of the secondary transformer units at the left side of the vehicle and / or one of the secondary transformer units at the right side of the vehicle is.
