Description

[Detailed description of the invention]

The present invention provides a transmitter that can be attached and detached from a storage device provided inside an automobile to operate an ignition system, and a locking mechanism that operates a locking mechanism of an automobile door using a signal from the transmitter. The present invention relates to an opening/closing system for automobile doors and trunk covers comprising a coupled receiver. In this type of motor vehicle, the transmitter is capable of activating or disengaging the locking mechanism of the motor vehicle door, as well as operating the ignition system. As for the trunk cover, known automobiles are equipped with a cylinder lock which can be opened and closed with a key, and therefore must be operated with a key in addition to the transmitter. Furthermore, automobiles are known in which the door locks are opened and closed with a key, while the trunk cover is electrically unlocked. The switch for releasing the electrical safety lock on the trunk cover is located inside the car, so even if you just need to use the trunk, you have to open the car door. The object of the invention is to improve, by simple means, the opening and closing system of a motor vehicle of this type in terms of easier operation and, at the same time, to improve the protection against unauthorized intervention in the trunk cover. This object is achieved by the features of claim 1. According to this, several switches are placed in the circuit of the control element for the electrically unlockable trunk cover, and the trunk cover can be unlocked both by a transmitter and from inside the vehicle. This ensures that the trunk cover is always closed in all other situations where the safety lock is not intentionally released. The interaction of the switches may be best understood by looking at Table 1 below and its associated explanation of possible cases. In Table 1, S ₁ is the first door that closes when the door is unlocked.
S ₂ represents a second switch that is closed when the transmitter is taken out from the storage device, and S ₃ represents a third switch that is an operating switch provided on or near the trunk cover. The closed state of the switch is represented by 1, and the opened state is represented by 0.

【table】

[Table] There may be cases where you want to open the trunk cover while the doors are locked and the engine is running (the transmitter is in the storage device) (for example, if a passenger wants to take something out of the trunk, or want to put something there, in this invention,
A fourth contact switch S ₄ is provided, which can be operated from inside the vehicle, making it possible to bypass the second and third switches. According to a preferred embodiment of the invention, a fifth switch _S5 is arranged in the circuit containing the control element, the locking mechanism of the motor vehicle door being selectively controllable by the main transmitter or the sub-transmitter, The transmitters are the 1st and 5th
switches are activated at the same time, the signal of the sub-transmitter can only affect the fifth switch in addition to the door locking mechanism, the fifth switch is closed when the door safety lock is released, and the It is designed to open when the lock is activated. The use of a main transmitter and a sub-transmitter ensures that operating comfort is not compromised and that the contents of the luggage compartment are kept safe when the vehicle is handed over to another person (for example in a repair shop or hotel). The state of the trunk cover in various switch positions is shown in the second section below.
Shown in the table. Switch S ₁ when operated by main transmitter
and S ₅ operate in parallel, so in this case Table 1 applies (same connection state for S ₁ and S ₅ ). Assuming that the door locking mechanism is operated by a secondary transmitter, Table 2 applies if the first switch S ₁ =0, ie the first switch is open. This means that the vehicle is once locked in its entirety by the primary transmitter, and then this vehicle is handed over to the user of the secondary transmitter (for example, a repair shop worker).

[Table] If the vehicle is handed over to the secondary transmitter user in an unlocked state, switch S ₁ remains closed throughout, and the secondary transmitter user therefore has the same possibilities as the primary transmitter user. . In other words, the trunk cover can be opened. Table 1 therefore applies. Motor vehicle users must therefore be aware that if they hand over their vehicle to someone with a secondary transmitter who is authorized only to enter the vehicle, the vehicle must first be locked with the primary transmitter. For this reason, the operation of switch S ₄ is similar to that of switch S ₁ .
It is valid only when both Switch S 5 and Switch S ₅ are closed. Hereinafter, two types of embodiments of the present invention will be described in detail based on the accompanying drawings. In the drawing, only the parts of the opening/closing system for the car door and trunk cover that directly affect the trunk cover 3 are shown. In FIG. 1, a lock 5 mounted on the rear cover 3 can be moved into the unlocked or locked position by means of an electrically operable control element 7.
The control element 7 is connected to a circuit 9 containing a plurality of switches. A first switch, designated S ₁ , is connected to a relay 11 operated by a receiver 13 paired with a transmitter 15 . When transmitting a signal from the transmitter 15, the locking mechanism (not shown) of the automobile door and the relay 11 are operated through the receiver 13. The connection between the door locking mechanism and relay 11 is
1 closes switch S ₁ when the door lock is released. The transmitter 15 is a housing device 1 located on the instrument panel of the automobile.
7 and can be pushed freely into the ignition system to operate the ignition system. Also, when the transmitter 15 is pushed into the housing device 17, the second switch _S2 of the circuit 9 opens. The third switch _S3 in the circuit 9 is designed as an operating switch (for example a key switch),
It can be operated from the outside by being located in a place where the hands can easily bend, such as on or near the trunk cover 3. As long as the first and second switches S ₁ and S ₂ are closed, press the operating switch S ₃ to unlock the lock 5 and close the trunk cover 3.
can be opened. The second and third switches S ₂ and S ₃ release the door lock mechanism, and when the trunk cover 3 is to be opened while the engine is running, the fourth switch S 2 and S 3 , which is disposed inside the vehicle as an operation switch, is used. Can be bypassed via ₄ . The embodiment shown in FIG. 2 is similar to FIG. 1, but the circuit 9 additionally comprises a fifth switch _S5 . This fifth switch _S5 and the first switch 1 placed next to it are connected to corresponding relays 19,1
1 are connected to each other. Both relays 19, 11
is the receiver 13 which responds to the signal from the main transmitter 15
is combined with The receiver 13 is also connected to a car door locking mechanism (not shown). Reception 13
receives the door opening signal from the main transmitter 15, the circuit 9 simultaneously switches the fifth and first switches _S5 ,
S ₁ closes. On the other hand, when the main transmitter 15 activates the door lock mechanism, the relays 19 and 11
opens the fifth and first switches S ₅ and S ₁ . A further relay 21 is coupled to the relay 19, which acts exclusively on the fifth switch _S5 .
A receiver 23 and a sub-transmitter 25 are provided to control the relay 21. Receiver 23 (which may constitute a single structural unit with receiver 13) is also coupled with relay 21 to the door lock mechanism. When the corresponding signal from the sub-transmitter 25 is received, the door is unlocked through the receiver 23 and at the same time the fifth switch _S5 is closed through the relay 21. The main transmitter 15 is a fifth and a first transmitter.
While switches _S5 and _S1 can be opened and closed at the same time,
The sub-transmitter 25 can only open and close the fifth switch _S5 . The first switch S ₁ remains in the position brought about by the last actuation of the main transmitter 15 in this case. This means that the switch _S1 remains open when the main transmitter 15 gives the last signal to "operate door lock", and therefore opening the trunk cover is absolutely prohibited by the sub-transmitter 25. It means possible. This is because the circuit 9 remains interrupted by the switch _S1 (ie, the safety lock is activated). On the other hand, if the last signal of the main transmitter 15 is "door lock release", the first switch _S1 is in the closed position and the sub-transmitter 25 performs the same operation as the main transmitter 15, i.e. The trunk cover 3 can also be opened. As described above, the automobile door and trunk cover opening/closing system of the present invention can be operated easily and reliably, and can prevent inappropriate intervention into the trunk room.
