Definitions

  • the invention relates to a door, in particular for a motor vehicle, according to the preamble of patent claim 1.
  • Such a door is known for example from DE 103 20 148 Al and comprises a door brake, by means of which an unintentional pivoting of a door of a motor vehicle can be prevented.
  • the door brake comprises a door-mounted braking device which acts on a brake rod, which is articulated at one end articulated to a body portion of the vehicle.
  • the braking device comprises an actuator.
  • An electric motor of the actuator drives a mechanism which acts on a wrap spring surrounding a bushing. The bush is penetrated by the brake rod.
  • a locked state acts on the socket, a clamping force on the brake rod, so that a pivoting of the door is prevented.
  • To release the clamping force is released by means of the actuator in response to a force applied to the door movement force.
  • braking is initiated by the braking device, and when the threshold value is exceeded, the braking device is caused to be brought into the release state.
  • This braking device has a complicated mechanical structure.
  • door brakes are known in practice, which are controlled in dependence on the closing or opening speed of the relevant door. In such a solution, a resistance to overcome the door brake is overcome. When the door is then set in motion, the pivoting process stops on closing only by a user holding the door.
  • the invention has for its object to provide a door of the aforementioned type with a door brake, which allows a stop of the door in any pivot position.
  • the essence of the invention consists in the fact that the braking device can be set by an operator by actuation of the at least one electrically switching valve targeted in a release state or a braking state. This is basically possible in any pivot position of the door. By releasing the brake device by switching the valve in the on position, substantially no resistance exerted by the brake device on the door is to be overcome when pivoting the door. Rather, the door can be stopped sensitively in any position over its pivoting range. The actuating forces for the braking device are minimized by the design of the valve as an electrically switching valve.
  • the electrically switching usually a solenoid valve performing valve by means of a arranged in the region of a door handle manual switch is solvable.
  • the door handle can anyway be provided on a vehicle door door handle and be attached to the vehicle outside or on the vehicle interior.
  • a manual switch for the brake device is arranged both in the region of a door handle attached to the vehicle exterior and in the region of a door handle attached to the vehicle interior side. Upon actuation or a gripping of the respective door handle by a user thus takes place a release of the braking device, whereby the brake rod relative to the braking device can move substantially freely. Otherwise, the braking device is preferably in the blocking position.
  • the door handle may be a movable door release handle or a handle provided rigidly on the door.
  • a plurality of manual switches can be arranged for releasing the brake device.
  • a manual switch is in a door unlocking handle and another handset is integrated into a handle provided immovably on the door.
  • the hand switch on the inside of the door can be optimally adapted to the respective conditions, the ergonomic design is not subject to constraints due to the low applied actuating forces for the handset.
  • the handset is for example a button or a non-contact sensor, such as a so-called Hall sensor.
  • a hand switch made of a contact foil or the like may be provided, which is arranged for example in the region of a window frame of the vehicle door and / or in another area of the vehicle door, to which a user preferably exerts a force when opening or closing the door.
  • the manual switch is designed so that the braking device is released at a pressure or a tensile force on the relevant door handle, the handset is then integrated, for example, in a door handle mechanism.
  • the door handle is released, the pivoting Operation of the door interrupted. It is therefore not possible to throw from a wide-open door position, which in turn reduces the risk of injury to a person through the door.
  • At least one distance sensor is arranged in the region of at least one door edge, which activates the braking device upon detection of an obstacle.
  • the distance sensor may be an anti-jamming device and / or a device which prevents a collision of the door with an obstacle, such as a vehicle or a garage wall, when it is opened. This can damage the door or even objects are prevented, which are an obstacle when swinging the door.
  • the braking device expediently comprises at least one hydraulic cylinder whose piston is connected to the brake rod.
  • the inflow or outflow of hydraulic fluid into a chamber of the hydraulic cylinder can be easily disabled or released by operation of the electrically-switching valve.
  • the hydraulic cylinder is a double-acting cylinder
  • the two chambers are each connected via a connection channel with a preferably common hydraulic circuit, which has a switching valve serving as an electrically switching valve for each chamber.
  • a switching valve serving as an electrically switching valve for each chamber.
  • the switching valves When the switching valves are open, the piston of the hydraulic cylinder is freely movable, and with closed switching valves, the movement of the piston of the hydraulic cylinder is locked.
  • the piston of the hydraulic cylinder is moved and shifted to the hydraulic fluid in the two 'chambers.
  • By closing the two switching or brake valves is the Door hydraulically blocked.
  • the two switching valves can be integrated in one unit and provided with a common magnetic actuator.
  • a ramp may be provided which holds the valve or valves open at least in the substantially closed state of the door.
  • This ramp may be formed electronically and comprise a displacement sensor or an angle sensor or may also comprise a mechanical actuator, such as a lever or a bowden cable, which acts on an electrical switch.
  • the displacement or angle sensor or the electrical switch is connected to a control unit of the door brake.
  • the control unit switches the valves to the defined opening angle1 in the passage position.
  • the ramp is adapted to hold the valves open up to an opening angle of the door of, for example, 15 °. The door can thus be freely pivoted and thrown within this area without pressing one of the manual switch.
  • the hydraulic circuit is provided in a preferred embodiment of the door according to the invention with a surge tank in which preferably acts by means of a spring-biased piston on a hydraulic fluid reservoir.
  • the connecting channels of the chambers are in a preferred embodiment via at least one bridging line connected to each other, in which a pressure relief valve is arranged.
  • a pressure relief valve and a throttle or the like may be provided in the bypass line.
  • the door brake is preferably designed so that the brake rod is pivotally articulated in the region of a body-mounted part of a door hinge and the braking device is fixed to the door. It is also conceivable, of course, to design the brake device body-mounted and to fix the brake rod pivotally attached to the door.
  • the single figure shows a door with a diagram of a door brake.
  • a door 10 of a passenger car is shown, which is articulated via a hinge 12 pivotally mounted on a vehicle body 16.
  • the pivot axis of the door 10 is formed by a hinge axis 14.
  • a body-mounted part is shown in the drawing.
  • the door 10 is provided with a hydraulically active door brake 18 which comprises a brake rod 20 which, via a hinge 22 so on the body-mounted part of the hinge 12 is fixed so that it is pivotable in a substantially horizontal plane.
  • the hinge 22 is spaced from the hinge axis 14.
  • the brake rod 20 passes through a hydraulic cylinder 24 assigned to a brake device, which is connected to the door 10 via a lug 26.
  • the brake rod 20 is connected to a piston 28 of the hydraulic cylinder 24.
  • the hydraulic cylinder 24 is designed as a double-acting cylinder, so that the piston 28 guided in a housing of the hydraulic cylinder 24 separates a first chamber 30 of the hydraulic cylinder 24 from a second chamber 32 of the hydraulic cylinder 24.
  • the piston 28 is seated on the brake rod 20, so that the brake rod 20 fully engages through the hydraulic cylinder 24. But it is also conceivable that the piston 28 is arranged at the free end of the brake rod 20, so that the second chamber 32 of the hydraulic cylinder 24 would not be penetrated by the brake rod 20.
  • the first chamber 30 of the hydraulic cylinder 24 is connected to a first connection or connection channel 34
  • the second chamber 32 of the hydraulic cylinder 24 is connected to a second connection or connection channel 36.
  • the two connection channels 34 and 36 lead to a valve unit 38, which comprises a first switching valve 40 and a second switching valve 42, which are actuated via a common magnetic actuator unit 46 and are biased by a spring 44 in the closing direction.
  • the actuating unit 46 is arranged via a control unit 70 with a hand switch 72, which is arranged in the region of a door inner handle and designed as a pushbutton, and in the region of an outside door. handle arranged, non-contact manual switch 74 connected.
  • the manual switches 72 and 74 are arranged so that the switching valves 40 and 42 are electrically switched to the transmission position by means of the actuating unit 46 as soon as a user grips the inside door handle or the outside door handle. Upon release of the respective door handle and the respective associated manual switch 72 and 74 switch the switching valves 40 and 42 due to an output from the control unit 70 to the actuator unit 46 electrical impulse in locked position, whereby the door brake 18 is active and counteracts a pivoting of the door 10 ,
  • the switching valves 40 and 42 are thus each connected in the open position, whereby a fluid flow between the first chamber 30 and the second chamber 32 of the hydraulic cylinder 24 is released via a bridge line 48.
  • hydraulic fluid flows from the second chamber 32 via the second connection channel 36, the second switching valve 42, the bridge line 48, the first switching valve 40 and first connection line 34 into the first chamber 30 of the hydraulic cylinder 24.
  • the fluid flow has a reverse direction.
  • the switching valves 40 and 42 are opened against the force of the spring 44.
  • the piston 28 of the hydraulic cylinder 24 can then be moved substantially without resistance in the cylinder housing, whereby the hydraulic fluid is displaced in the cylinder.
  • the switching valves 40, 42 are closed, the fluid flow between the two chambers 30th and 32 of the hydraulic cylinder 24 locked, resulting in a hydraulic locking of the door 10.
  • a distance sensor 66 is arranged in the region of an edge of the door 10 facing away from the hinge 12 and, when an obstacle is detected, causes the switching valves 40 and 42 to be switched into blocking position by means of the control unit 60, so that the door 10 can pivot further and a collision of the door 10 is prevented with the obstacle.
  • the control unit 70 is designed so that the circuit of the switching valves 40, 42 in blocking position upon detection of an obstacle also takes place when one of the manual switches 72 and 74 is actuated.
  • two bridging lines 56 and 58 are arranged between the first connection channel 34 and the second connection channel 36, in each of which a pressure relief valve 60 or 62 designed as a check valve is arranged.
  • the relief valves 60 and 62 prevent a force exerted on the door 10 when the switching valves 40, 42 are closed, leading to the destruction of the hydraulic devices.
  • the door 10 can therefore also be used with closed switching valves 40 and 42, i. be moved without actuation of the braking device 18, but then only with an increased effort.
  • the bridge line 48 is connected to a surge tank 50, in which a hydraulic fluid reservoir held is, on which a biased by a spring 52 piston 54 acts. It is thus automatically adjusted if necessary hydraulic fluid.
