However, since this type of trunk lid employs a manual opening / closing operation, it is necessary for an occupant or the like to go to the installation position of the trunk outside the vehicle to perform the opening / closing operation.

In particular, when the area of the side opening of the luggage compartment is large, the lid becomes heavy, which makes the work difficult.

Therefore, recently, a trunk lid opening / closing device for opening / closing the lid by using a working fluid such as compressor air as a power source has been developed and put into practical use.

This electrically controls the flow of the working fluid in accordance with the operation of the open / close switch and drives the open / close mechanism, which is convenient because it does not require manual work by an occupant or the like.

(Problems to be solved by the invention) Incidentally, in such a trunk lid opening / closing device, it is not preferable in terms of safety to open the lid when the side brake of the vehicle is not applied.

This invention was made in view of the above circumstances,
It is an object of the invention to provide a trunk lid opening / closing device with excellent safety that can prohibit the opening of the lid when the side brake is not applied.

As shown in FIG. 6A, a blocking flow path between the ports 22a and 22d and an opening flow path between the ports 22a and 22e are formed. When the opening solenoid B is energized, as shown in FIG.
Opening flow path between e and port 22b and port 22
It forms a flow path with d. In the energized state of the closing solenoid A, a closing flow path between the ports 22a and 22d and a flow path between the ports 22c and 22e are formed as shown in FIG.

FIG. 11 (a) shows the non-energized state of the closing circuit switching valve 28, and FIG. 11 (b) shows the passage in the energized state. FIG. 12 (a) shows the non-energized state of the unlocking prevention flow path switching valve 33, and FIG. 12 (b) shows the flow path in the energized state. Thirteenth
FIG. 7A shows the unlocking flow passage switching valve 30 in the non-energized state,
FIG. 2B shows the flow paths in the energized state.

Next, the operation of the above configuration will be described.

First, when the main switch 51 is turned on, the open / close switch 39 is turned on or the open / close switch 41 is once turned to the open side, the input terminal IN of the open / close switch circuit 60 is opened.
And the output terminal OUT are electrically connected, and the relay 54 is energized.

Then, an opening command is input to the control unit 55, the control unit 55 sounds the buzzer 77 for a predetermined time, for example, 0.8 seconds, and energizes the relay 81. At the same time, the lock release passage switching valve 30 and the lock release prevention passage switching valve 33 are energized.

At this time, the flow path switching valve 22 and the closing circuit switching valve 28
Since each is in the non-energized state, the air supplied from the air tank 21 is supplied to the air cylinder 8 as shown in FIG.
Air cylinders 8a, 8 from the ports on the tip side of a, 8b
Each of the air is introduced into the inside of b and air is supplied in the closing direction of the lid 3. Further, since air is supplied to the lock release air cylinder 19 at the same time as air is supplied in the closing direction of the lid 3, the lock release air cylinder 19 is also supplied.
Rotating member 1 that does not follow the projecting movement of the piston rod 20 of
4 is rotated in the direction opposite to the urging direction of the return spring 18, and each hook of the lock mechanism 12 is locked by the striker 1.
The lock mechanism 12 is moved in the unlocking direction with respect to 7 ...
Is unlocked.

When the lock mechanism 12 is unlocked, the first stroke switch 35 of the unlock air cylinder 19 is turned on. Then, since the opening solenoid B of the flow path switching valve 22 is energized, the air circuit is changed from the state shown in FIG. 14 to the state shown in FIG. 15, and the air supplied from the air tank 21 side is supplied to the air cylinders 8a, 8b. Enter from the port on the base end side of
The air cylinders 8a and 8b open the lid 3 as shown by the phantom line in FIG.

In this open state, since the relay 81 is energized, the relay 83 is also energized, and the positive voltage line X contacts the contact 8
It is directly connected to the battery power source 50 via 3a. Therefore, even if a third person accidentally turns off the main switch 51 or the manual setting switch 53, the energization of the opening solenoid B of the flow path switching valve 22 continues, and the open state of the lid 3 can be maintained.

That is, it is possible to prevent the lid 3 from unnecessarily falling and ensure the safety of the occupant and the like.

By the way, when the side brake is not applied, the park switch 84 is in the ON state. Therefore, even when the main switch 51 is off and the open / close switch circuit 60 is not conducting, the closing solenoid A of the passage switching valve 22 is set 83.
b through the park switch 84 and the battery power source 50
Directly connected to.

Therefore, if the side brake is forgotten to be applied when the vehicle is stopped or parked, a force in the closing direction always acts on the lid 3, and the lid 3 is not opened even if the opening operation is performed, which is safe.

That is, in a dangerous situation in which the vehicle may start moving, luggage is prohibited from entering and leaving the luggage compartment 2 to ensure sufficient safety.

When the lid 3 is opened, the lid switch 75 is turned on. When the side brake is released while trying to drive the vehicle as it is, the buzzer 87 sounds in response to the turning on of the park switch 84 and an occupant is alerted. Is emitted.

On the other hand, when the lid 3 is opened and the open / close switch 39 is turned off or the open / close switch is tilted to the closed side, the open / close switch circuit 60 is turned off and the relay 5 is opened.
4 is deenergized, and the control unit 55 receives a close command.

Then, the control unit 55 deactivates the relay 81 so that the closing solenoid A of the passage switching valve 22 and the closing circuit switching valve 28 are energized, and the unlocking prevention passage switching valve 33 is de-energized. The air circuit changes from the state shown in FIG. 15 to the state shown in FIG. Therefore, the air supplied from the air tank 21 side enters through the ports on the tip side of the air cylinders 8a and 8b, and closes the lid 3. In this case, since the pressure reducing regulator 27 is provided in the air supply passage that is supplied from the air tank 21 side to the ports on the tip side of the air cylinders 8a and 8b, the regulator 27 is provided.
By this, the air supply speed is suppressed, the closing operation speed of the lid 3 is reduced, and the lid 3 is closed relatively slowly.

It should be noted that during the closing operation of the lid 3, the light emitter 34 of the photodetector 34 that is arranged in the vicinity of the side opening of the trunk room 2 is opposed to the light detector 34.
When the light between a and the light receiver 34b is blocked by an occupant or the like, the control unit 55 immediately activates the relay 81,
The energization of the flow path switching valve 22 is switched from the closing solenoid to the opening solenoid B. That is, switching to the closing flow path side is prohibited, and the closing operation of the lid 3 is stopped. Therefore, the safety of the human body can be ensured.

When the piston rod 10b of the air cylinder 8b moves by a predetermined stroke to close the lid 3 by a predetermined amount or more, the third stroke switch 37 is turned on. Then, the relay 57 is energized, the electricity to the phototube circuit 78 is cut off, and the operation of the photodetector 34 is stopped.

That is, in a situation where the lid 3 is closed more than a predetermined amount and the support arm 5 of the opening / closing mechanism crosses the opening of the trunk room 2, the operation of the photodetector 34 is stopped and the lid 3 is closed halfway. I try to avoid such inconvenience. As a result, sufficient safety can be secured when the lid is closed, and reliability can be improved.

Further, during the closing operation of the lid 3, the second stroke switch 36 is turned on when the piston rod 10a of the air cylinder 8a moves by a predetermined stroke. When the second stroke switch 36 is turned on, the relay 71 is energized to turn off the closing circuit switching valve 28, the air circuit is switched from the state shown in FIG. 16 to the state shown in FIG. 14, and the air tank 21 The air supplied from the side to the tip side ports of the air cylinders 8a and 8b bypasses the regulator 27 through the bypass passage 29. As a result, the closing speed of the lid 3 increases immediately before the closing. That is, this is to ensure that the lid 3 is closed regardless of the elasticity of the weather strip.

Then, as soon as the lid 3 reaches the closed position, the lid 3
Of the lock mechanism 12 is locked by the lock mechanism 12 to lock the lid 3 at the closed position.

On the other hand, when the manual setting switch 53 is turned off, the flow path switching valve 22, the closing circuit switching valve 28, the lock release preventing flow path switching valve 33, and the lock release flow path switching valve 30 are each in a non-energized state. Becomes Therefore, the air circuit is in the state shown in FIG. 18, and the air supplied from the air tank 21 side is introduced to both sides of each piston of the air cylinders 8a and 8b. This allows the lid 3 to be opened and closed manually.

Further, by manually operating the exhaust valve 24 in an emergency, the air circuit becomes an emergency circuit shown in FIG. 19, and the air in the air cylinders 8a, 8b is exhausted to the outside via the exhaust valve 24.

By the way, regarding the operation of the open / close switch circuit 60, when the open / close switch 39 is turned on, a conduction path from the input terminal IN to the output terminal OUT is formed via the normally closed side of the open / close switch 39 and the contact 61a. Thereby, the lid 3 can be opened.

With the open / close switch 39 turned on, the open / close switch 41
Is operated to the closed side, the contact 41
The relay 61 is energized via a and the power supply to the output terminal OUT is cut off. In this case, the relay 61 forms a self-holding circuit via its own contact 61a and contact 63a. As a result, the power supply to the output terminal OUT is cut off,
The lid 3 can be closed.

Then, if the open / close switch 41 is operated to the open side from this state, the relay 63 is energized to release the self-holding circuit of the relay 61, and the energization path to the output terminal OUT is formed. As a result, the lid 3 can be opened.

Further, if the open / close switch 39 is turned off from this state,
Only by that, the power supply path to the output terminal OUT is cut off. As a result, the lid 3 can be closed.

That is, the occupant may operate the opening / closing switch 39 on the driver's seat side and then the opening / closing switch 41 on the entrance / exit side. Conversely, the occupant operates the opening / closing switch 41 on the entrance / exit side and then the driver's seat side. The opening / closing switch 39 may be operated, and in any situation, the lid can be opened / closed appropriately with the latest operation being prioritized.

In particular, if the opening / closing switch 41 at the entrance / exit is used, the state of the lid 3 can be viewed during the operation, which improves safety. In addition, it is not necessary to go to the operating seats for each operation during the work in the trunk room 2, and the operability is improved, which is convenient.

Although air is used as the working fluid that is the power source of the opening / closing mechanism in the above embodiment, hydraulic pressure may be used.

Besides, the present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the scope of the invention.

[Advantage of the Invention] As described above, according to the present invention, an opening / closing mechanism provided in the trunk room for opening / closing the lid by using the working fluid as a power source and the opening / closing mechanism and the working fluid supply source are provided. A flow path switching valve for selectively forming an opening flow path and a closing flow path for the open / close mechanism, an open / close switch for instructing opening / closing of the lid, and the flow path switching according to an opening operation of the open / close switch. Means for switching the valve to the opening flow path side, means for switching the flow path switching valve to the closing flow path side in response to the closing operation of the opening / closing switch, and operation of the opening / closing switch when the vehicle side brake is not applied Regardless of the above, since there is provided means for switching the flow passage switching valve to the closing flow passage side, it is possible to prohibit opening of the lid when the side brake is not applied, which is excellent in safety. A trunk lid opening / closing device can be provided.
