Abstract
The present invention relates to a releasable holding mechanism which may be used to hold and release a roll bar in a roll over protection system. The roll bar is often made part of the seat structure of vehicle, or a part of the chassis of the vehicle. The releasable holding mechanism will be fastened rigidly or slightly loose to the roll bar frame, seat frame or the chassis of the vehicle. Between the roll bar and the releasable holding mechanism there will be a connection element that is rigidly or slightly loosely fastened to the roll bar. The arrangement of fastening the connection element rigidly or slightly loosely depends on the tolerances for positioning the actuator towards the roll bar. The connection element is locked or released by the releasable holding mechanism. The releasable holding mechanism is locked/-engaged when the roll bar is pushed downwards whereby the connection element is forced into the releasable holding mechanism. The releasable holding mechanism is to release the connecting element when a signal is sent to the release element of the holding mechanism. The releasable holding mechanism can be activated by one short duration pulse, for instance a pulse from an electronic control unit for activation of airbags in a vehicle. The system can be activated with low energy demands.
Description
Technical field
But the present invention relates to a kind of release holding mechanism and a kind of method that is used to encourage this mechanism that is used for mechanism is remained on the device of lock-out state that have, especially relate to but be not limited to the releasable maintaining body that a kind of steam supply car overturning protection system (ROPS), releasable head rest, backrest, the cover that is used for pedestrian protecting and other automobile are used.
The present invention especially designs for ROPS, but also can be suitable for the place that other need discharge constant load, for example marine safety equipment, liferaft (as the replacement of rope-cutter device), fix and discharge goods and be used for releasing mechanism of aviation or the like.
Background technology
Overturning protection system (ROPS) is installed in the vehicle, with protection chaufeur and passenger under the situation of vehicle overturning.During normal driving, overturning bar or protection member are stored in lower retracted position.When overturning and one or several sensor received signal from vehicle take place, have only roll bar to be released and be raised to the higher position.
Known roll bar is upspring towards the higher position usually, but is held back in the lower position by releasable maintaining body, and keeps roll bar via one or more Connection Elements.Thereby the maintaining body that is positioned at latched position remains on lower position with roll bar, and the maintaining body that is positioned at the releasing position allows roll bar to be lifted to the higher position.
ROPS can comprise one or more roll bars that separate or protection member, and each uses a maintaining body.Several protection members also can utilize a maintaining body to link together.This maintaining body faces several problems when being used for the overturning protection system:
-harsh environmental conditions is for example vibrated, is toppled over, dust and humidity, may cause roll bar or is fastened on lower position or discharges unintentionally.
The allowance error of-vehicle chassis and skew form orientation problem, may cause roll bar to discharge nothing or fastening unintentionally.
The power and the expenditure of energy of-releasing mechanism should be very little, with the needs of the extra power of avoiding supplying with similar cond.Desirable mechanism can directly provide power by the collision control unit.
-maintaining body should recover again.This means, after being released, when manually or by another power promote downwards/when spurring, the roll bar Connection Element should be engaged in latched position once more.
According to relevant prior art, be used for the releasable maintaining body of overturning protection system or encourage by electromechanical device excitation or by pyrotechnic device.Roll bar is retained in lower position by mechanical pallet holding element, and up to a given signal, roll bar just is released.Such mechanism depends on the release configuration of working, and encourages the actuator of certain form thus, so that mobile piston or rod element and the described pallet holding element of unblanking, the pallet holding element discharges roll bar conversely, is used for launching.
The pyrotechnics actuator is based on such principle, that is, a small amount of propellant is lighted, and pressure can be used to disconnect lockout mechanism.Subject matter is that they do not recover again, after the use, must be replaced.
Known electromechanical actuator, for example DE 100 02 723 disclosed actuators have pipe link between roll bar and actuator.This pipe link for example utilizes inclined-plane (conical surface) and ball to be directly connected to more or less to discharge on the magnet coil, so that roll bar is locked in lower position.This solution is disadvantageous, and the small skew of pipe link will cause the direct motion at releasing mechanism locking ball.Therefore roll bar may be released unintentionally.This mechanism also partly open is polluted.When actuator discharged, the direct connection between pipe link and the releasing mechanism needed higher power and expenditure of energy, because actuator must be revolted most of spring load work.
Another example that comprises the releasing mechanism of solenoid actuator is the releasing mechanism of describing among the patent specification US5626361 of BayerischeMotoren Werke AG.
In US Patent 5,228, disclose a kind of instantaneous power that utilizes in 730 mechanical caging has been converted into electric apparatus operating.Lock-button can limit (arrest) by means of stop pin.Motion by means of the electromagnet that makes up and permanent magnet and spring generation stop pin.By the polarity of checker electric power, the position of stop pin can conversion between latched position and lockset position of coupler.The maintenance of this solution and prestension Connection Element and release are irrelevant.
