Definitions
- Vehicle door with a handle arrangement Vehicle door with a handle arrangement.
- the invention relates to a vehicle door with a handle arrangement for initiating an opening signal or a locking signal of the door and to a method for opening or locking a vehicle door.
- a flush-mounted door handle which is designed to be movable at least between a rest position and an open position, wherein in the rest position the door handle is flush with the outside door panel and in the open position the door handle protrudes from the outside door panel.
- the disadvantage is the high construction effort required for the movable mechanism.
- the object of the invention is to overcome the disadvantages of the prior art and to provide a vehicle door which has a simple construction and is easy to operate by a user.
- a vehicle door comprising: an outer door panel and an inner door panel; a handle assembly having a housing which has a
- Handle section and an electronics receiving section and is arranged on a shaft reinforcement plate of the door, wherein a circuit board is provided in the electronics receiving section, on which a sensor is arranged, wherein the handle section protrudes from the door outer panel plane is provided and the electronics receiving section is provided between the outer door panel and the inner door panel; a conductive, in particular metallic, activation element, wherein the position of the sensor relative to the activation element can be changed by the user exerting force on the handle section, thereby causing an opening signal or a locking signal for the door.
- the body of the handle arrangement is a housing.
- the vehicle door designed in this way enables a compact design that requires less installation space than vehicle doors with conventional door handle arrangements. Since the handle section protruding from the door's outer panel level can now be reduced to the absolutely necessary size in terms of design freedom, the aerodynamic properties of the door are significantly improved.
- the shape of the handle section can itself represent a design feature.
- the body or housing is made monolithically from plastic. This enables optimal sealing of the body or housing.
- the body or housing is constructed in a shell design from several shells.
- the handle arrangement also enables comfortable operation. In the rest position, the handle section is fixed to or on the door.
- the user exerts a pressure force or a pulling force, preferably of at least 15 N, on the handle section so that the electronics receiving section is moved along and leaves its original position.
- the aim is to change the position of the sensor relative to the activation element.
- the activation element can be arranged directly or indirectly, rigidly or movably in the door.
- the activation element can be designed as an additional component such as a metal foil or a metal strip on a door component, as a metal coating on a door component or integrated into a door component.
- the arrangement can be designed in such a way that the position of the activation element is not influenced by the force exerted by the user on the handle section. Alternatively the activation element can be moved when the user applies force.
- the body or housing of the electronics section is designed as a shell that is open towards the interior of the vehicle.
- the open side can be sealed with a potting material to protect the circuit board from environmental influences such as moisture, water or dust.
- the circuit board can be embedded in the potting material.
- the potting material can surround a space formed in the electronics section or around the circuit board.
- the senor delivers a signal that is representative of a distance between the sensor and the activation element.
- the sensor can be an inductive sensor, in particular a so-called inductance-to-digital converter (LDC) sensor.
- LDC inductance-to-digital converter
- the change in distance is detected by the frequency shift caused by the oscillating circuit of the sensor.
- the sensor can be a capacitive sensor.
- the change in distance is detected by means of a change in capacitance between the sensor and the activation element.
- the sensor behaves as a measuring electrode and the activation element as a reference electrode.
- the body or the housing of the handle arrangement has a fastening point between the handle section and the electronics receiving section, as a result of which the handle arrangement is supported by the upper edge of the shaft reinforcement plate.
- the handle arrangement can be supported directly by the upper edge of the shaft reinforcement plate or indirectly via the outer door plate, in the situation that the upper edge of the shaft reinforcement plate is flanged by the upper edge of the outer door plate, by the upper edge of the shaft reinforcement plate.
- the fastening point can, for example, be designed as a recess in the body or housing, as a result of which the handle arrangement is plugged onto the upper edge of the shaft reinforcement plate. In this way, a stable and at the same time assembly-friendly fastening of the handle arrangement is guaranteed.
- the elastomer of the sealing material When the user exerts force on the handle section, the elastomer of the sealing material is pressed against the upper edge of the shaft reinforcement plate or the upper edge of the outer door plate flanged around the upper edge of the shaft reinforcement plate. pressed against the upper edge of the outer door panel, which is folded over the upper edge of the shaft reinforcement panel, so that the handle assembly leaves the rest position. Once the user has stopped exerting force, the elastomer is automatically reset. The handle assembly is also moved back to the rest position.
- a metal insert is preferably embedded in the elastomer as a reinforcing part.
- the sealing element can be designed separately from or as an extension of the shaft seal, which extends along the window opening to prevent water and dirt from entering the interior of the door via a gap between the window pane and the outer door panel.
- the force exerted is a pulling force or a pushing force by the user, whereby when the handle section is pulled the opening signal of the door is initiated and when the handle section is pressed the door locking signal is initiated.
- a second circuit board can be arranged in the handle section, on which an NFC antenna and/or a proximity sensor, in particular a capacitive proximity sensor, are arranged in order to detect the presence and/or approach of the user. After the user is detected, the sensor electronics in the electronics receiving section are woken up. This means that the sensor electronics can be operated in an energy-efficient manner.
- NFC communication enables a secure and contact-free exchange of access data between the vehicle and an active access device, e.g. a cell phone, tablet, etc., or a passive access device, e.g. a user card.
- the NFC communication interface also enables energy transfer in an emergency if the vehicle battery is empty or if the accumulator of the access device is empty.
- the shaft reinforcement plate is designed as an activation element or the activation element is arranged on the shaft reinforcement plate.
- the handle arrangement together with the sensor arranged in the electronics receiving section, moves closer or further away from the shaft reinforcement plate, so that a parameter change of the sensor is detected.
- a sealing part can be arranged on the activation element, in particular between the activation element and the outer wall of the housing of the electronics receiving section, wherein the sealing part consists in particular of a sealing pad or a sealing ring made of elastic material in order to eliminate possible disruptive influences such as protection, water or moisture.
- the swing section can be an extension of an inner reinforcement part of the handle section, which is injection-molded or glued to the inner wall of the handle section.
- the body of the handle arrangement is a housing.
- the force exerted is a pulling force or a pushing force, whereby when the handle portion is pulled, the
- a vehicle door according to the invention can be used for the method according to the invention. Advantages and preferred developments of the proposed method result from an analogous and analogous transfer of the in connection with the proposed vehicle door.

- Fig. 2 the handle arrangement according to Fig. 1
- Fig.4a the schematic sketch of the relative position representation between the sensor and the activation element in the rest position of the handle arrangement according to the embodiment in Fig. 3
- Fig. 5 a vehicle door in a schematic sectional view in a further embodiment
- Fig.6c the schematic sketch of the relative position representation between the sensor and the activation element in the rest position of the handle arrangement under the force F2 according to the embodiment in Fig. 5
- Fig. 2 shows that the handle arrangement has a handle section 5 and an electronics receiving section 6.
- the handle section is arranged so as to protrude from the door outer panel plane, while the electronics receiving section is provided between the door outer panel and the door inner panel and is therefore invisible from the outside of the vehicle.
- a circuit board 7 is provided in the housing of the electronics receiving section, on which a sensor 8 is arranged.
- the sensor 8 is an inductive sensor which is based on the so-called inductance-to-digital converter (LDC) technology.
- LDC inductance-to-digital converter
- the conductive activation element 11 is attached to the shaft reinforcement plate 10 at the level of the sensor.
- the activation element 11 can be designed as a metal foil, a metal strip or a metal coating on the shaft reinforcement plate 10.
- Between the activation element 11 and the outer wall of the housing of the A sealing pad 12 is arranged in the electronics receiving section 6 and is designed to be elastically compressible.
- This sealing element is also plugged onto the upper edge of the outer door panel and thus encloses the upper edge of the shaft reinforcement panel.
- the sealing element is not explicitly shown in Fig. 5.
- the handle arrangement 4 is attached via a fixed bearing 17 to the arrangement bracket 16 of the shaft reinforcement plate 10.
- the circuit board 7 is provided in the electronics receiving section 6 in such a way that it is only fixedly mounted on the housing of the electronics receiving section 6 at the lower end as viewed in the vehicle's Z axis and the rest of the circuit board can swing freely in the housing.
- the sensor 8 is aligned facing the shaft reinforcement plate 10.
- Fig. 4 also shows that the activation element 11 is arranged opposite the sensor 8 on the inner wall of the housing.
- the activation element 11 can be designed as a metal foil, a metal strip or a metal coating.
- the relative position change between the sensor 8 and the activation element 11 is shown in Fig. 6a to 6c.
- the relative position change is shown disproportionately in the schematic sketches and not to scale.
- Fig. 6b it can be seen that the housing 6 is deformed by the user exerting a pulling force Fl.
- the circuit board 7 is only connected to the housing at its lower end and the opposite end section, where the sensor 8 is arranged, is designed to be movable in an oscillating manner, the distance between the sensor 8 and the activation element 11 is thus increased.
- the distance between the sensor 8 and the activation element 11 is reduced by the user exerting a compressive force F2 on the handle section, as can be seen in Fig. 6c.
- a vehicle door 2 according to the invention is shown in a further embodiment in a schematic sectional view.
- Fig. 7 shows the arrangement of the handle arrangement 4 in the non-actuated rest position in relation to the outer door panel 3, inner door panel 13 and shaft reinforcement panel 10 of the door 2. Similar to the embodiment in Fig. 3, the handle arrangement 4 is attached at its fastening point 14 to the upper edge of the shaft reinforcement panel 10 or the outer door panel 3. For sealing, a sealing strip is placed between the upper edge of the outer door panel 3 and the fastening point 14 of the Handle arrangement 4 has a U-shaped sealing element made of elastomer which is upside down in cross section, as shown in Fig.
- the handle arrangement 4 is attached to an arrangement bracket 16 of the shaft reinforcement panel 10 via a fixed bearing 17.
- the circuit board 7 is fastened in the electronics receiving section.
- the sensor 8 is oriented away from the shaft reinforcement plate 10. It is also conceivable that the circuit board 7 is fixedly mounted on the housing of the electronics receiving section at only one of the ends, as viewed in the vehicle Z axis, as shown in Fig. 5. The circuit board is thus also designed to be able to swing.
- Fig. 8a and 8b the relative position change between the sensor 8 and the activation element 11 is shown.
- the relative position change is shown disproportionately in the schematic sketches and not to scale.
- Fig. 8b it can be seen that the housing 6 is deformed by the user exerting a pulling force Fl and the sensor 8 thus deviates from its original position. Because the oscillating section 18 is only connected to the housing at its upper end and the opposite end section, where the sensor 8 is arranged, is designed to be movable, the distance between the sensor 8 and the activation element 11 is thus increased. In contrast, the distance between the sensor 8 and the activation element 11 is reduced by the user exerting a compressive force F2 on the handle section, as can be seen in Fig. 8c.
- Fig. 9 shows the detailed view of the sealing element 19, which can be used in embodiments of Fig. 3, 5 and 7.
- the upper edge of the outer door panel 3 is on the upper edge of the Shaft reinforcement plate 10 is flanged.
- An upside down U-shaped sealing element 19 is placed on the upper edge of the outer door panel 3. Lips 20 protrude from the inside of the sealing element 19, which serve as an elastically effective clamping attachment and are compressed when a force is applied.
- the sealing element 19 thus offers an even greater degree of deformation.
- the sealing element is further reinforced by a metal insert 21 with a strip-shaped cross section, which is embedded in the elastomer of the sealing element 19.
