Abstract

PURPOSE:To prevent an interference between a hood storing lid and a trunk lid by means of a simple constitution by constituting the system in such a way that both lids are opened by means of separate driving means and a power source circuit for a driving means to open one lid is cut off once the other lid is opened. CONSTITUTION:When both a hood storing lid 5 and a trunk lid 6 are in a closed state, respective lid state detecting switches 21, 15 are in an OFF state. At this time, coils of open-cancel-relays 13, 19 for the hood storing lid and the trunk lid are in an unexcited state, while their relay switch moving contacts are in an ON state. If, for example, a hood storing lid opener switch 14 is turned ON in this state, the coil of a hood storing lid opener relay 12 is excited, and the hood storing lid 5 is opened by an actuator 10. Since the hood storing lid state detecting switch 21 is turned ON at this time, the coil of the relay 19 is excited. As a result, the relay switch moving contact of the coil is turned OFF, and a power source circuit 17 is cut off.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing interference between a top storage lid and a trunk lid located at the rear of a convertible vehicle.

0002

2. Description of the Related Art Conventionally, a device having the structure shown in FIG. 4 has been put into practical use as a device for preventing interference between a top storage lid and a trunk lid (for example, BMW Z-1
). That is, at the rear of the convertible vehicle 1, a hood storage section 2 and a trunk room 3, which are partitioned by a bulkhead 9, are provided adjacent to each other. The hood storage section 2 is a space in which a hood (not shown) that covers the upper part of the vehicle interior 4 is folded and stored, and a hood storage lid 5 that can be opened and closed to cover the stored hood is pivotally mounted on the upper part. The trunk compartment 3 has a trunk lid 6 covering the top opening.
is installed at the center.

The hood storage lid 5 and the trunk lid 6 are rotatable with one end edge 7, 7a adjacent to each other as pivot sides, and when one of the lids 5, 6 is operated to open. The two lids 5 and 6 are connected via a link 8 that can prevent the other lid 5 and 6 from being opened. The bulkhead 9 is provided with a through hole H, and the link 8 is
It is arranged across the hood storage section 2 and the trunk room 3 via this through hole H.

In this structure, when the trunk lid 6 is opened, for example, as shown by the broken line, the link 8 is opened.
This action prevents the opening operation of the top storage lid 5. This prevents the inconvenience that when both lids 5 and 6 are opened at the same time, the lids 5 and 6 interfere with each other and cause damage to their respective surfaces. In other words, in the convertible vehicle 1 in which the top storage lid 5 and the trunk lid 6 are arranged side by side, it is difficult due to the vehicle body layout to open both lids 5 and 6 at the same time without interfering with each other. 8 prevents both lids 5 and 6 from being opened simultaneously, thereby preventing interference between the lids 5 and 6 and damage caused by the interference.

[0005]

[Problems to be Solved by the Invention] However, in such a conventional device, the link 8 that connects both the lids 5 and 6 and operates as the lids 5 and 6 are opened, It has a structure that mechanically prevents both lids 5 and 6 from being opened at the same time. Therefore, not only the space required for the existence of the link 8 itself, but also the space required for the operation of the link 8 is taken up by the hood storage section 2 and the trunk room 3.
As a result, the storage space of the hood storage section 2 and the trunk room 3 is significantly reduced. Furthermore, when the link 8 is disposed across the top storage section 2 and the trunk room 3 in this way, it becomes necessary to provide a through hole H in the bulkhead 9 through which the link 8 can operate. Therefore, there also arises a problem that the airtightness of the trunk room 3 cannot be ensured.

[0006] The present invention has been made in view of the above-mentioned problems in the prior art, and it is possible to improve the structure of the top storage lid without reducing the storage space of the top storage space or the storage space of the trunk compartment, and while maintaining the airtightness of the trunk compartment. It is an object of the present invention to provide an interference prevention device between a hood storage lid and a trunk lid that avoids interference with the trunk lid.

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a hood storage lid that can be opened and closed to cover a stowed hood and a top opening of a trunk room, like a convertible car. In a vehicle where a trunk lid that can be opened and closed interferes with each other when they are opened at the same time, a first electric drive that opens the top storage lid in response to turning on an operation switch inserted in a power supply circuit. and a second electrical drive means for driving the trunk lid open in response to turning on of an operation switch inserted in a power supply circuit, and a second electric driving means for driving the trunk lid to open when the trunk lid is in the open state. a first relay that interrupts the power supply circuit of the first electric drive means when the top storage lid is in an open state; and a first relay that interrupts the power supply circuit of the second electric drive means in response to the top storage lid being in an open state; A second relay is provided.

[0008]

[Operation] In the above structure, for example, when an operation switch inserted in the power supply circuit of the second electric drive means is turned on, the second electric drive means is operated and the trunk lid is driven to open. It becomes open. Then, the first relay interrupts the power supply circuit of the first electric drive means in response to the opening operation of the trunk lid. Therefore, when the trunk lid is in the open state, even if the operation switch inserted in the power supply circuit of the first electric drive means is turned on, the top storage lid will not be driven open.

[0009] Furthermore, for example, when an operation switch inserted in the power supply circuit of the first electric drive means is turned on, the first electric drive means is operated and the top storage lid is driven to open. state. Then, the second relay interrupts the power supply circuit of the second electric drive means in response to the opening operation of the top storage lid. Therefore, when the top storage lid is in the open state, the trunk lid will not be driven open even if the operation switch inserted in the power supply circuit of the second electric drive means is turned on.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 2, at the rear of the convertible vehicle 1, a hood storage section 2 and a trunk room 3, which are separated by a bulkhead 9, are provided adjacent to each other. The hood storage section 2 is a space in which a hood (not shown) covering the upper part of the vehicle compartment 4 is folded and stored,
A hood storage lid 5 that can be opened and closed is pivotally mounted on the upper part of the trunk compartment 3, and a trunk lid 6 that covers the upper opening of the trunk compartment 3 is pivotally mounted thereon. The hood storage lid 5 and the trunk lid 6 are rotatable with one end edge 7, 7a adjacent to each other as pivot sides, and due to the vehicle body layout, when both lids 5, 6 are opened at the same time, As shown in FIG. 3, both lids 5,
6 inevitably interferes with each other.

[0011] A top storage lid actuator 10 for driving open the openable and closable top storage lid 5 is disposed at the upper part of the top storage section 2. As shown in FIG. The hood storage lid actuator 10 is a first actuator that operates using an on-vehicle battery as a power source.
This is an electrical driving means for a motor, and as shown in FIG. 1, it has a power supply circuit 11. In the power supply circuit 11, the top storage lid actuator 10 has one end grounded and the other end connected to one fixed contact of the top storage lid opener relay 12. The hood storage lid opener relay 12 is normally open, and the other fixed contact is connected to the anode (+B) of the vehicle battery.

Furthermore, one end of the coil of the top storage lid opener relay 12 is grounded, and the other end is connected to one fixed contact of the top storage lid open cancel relay 13, which constitutes the first relay in this embodiment. It is connected to the. The hood storage lid open cancel relay 13 is normally closed, and the other fixed contact is connected to the anode (+B) of the vehicle battery via a normally open hood storage lid opener switch 14, which is an operation switch.

The coil of the hood storage lid open cancel relay 13 has one end connected to the anode (+) of the vehicle battery.
B), and the other end is grounded via the trunk lid state detection switch 15. The trunk lid state detection switch 15 is turned off when the trunk lid 6 is in a closed state, and turned on in response when the trunk lid 6 is in any open state other than closed. ing.

Further, a trunk lid actuator 16 is disposed in the upper part of the trunk room 3 to open the trunk lid 6, which can be opened and closed. The trunk lid actuator 16 is a second electrical drive means that operates using an on-vehicle battery as a power source, and has a power supply circuit 17. In the power supply circuit 17, the trunk lid actuator 16 has one end grounded and the other end connected to one fixed contact of the trunk lid opener relay 18. The trunk lid opener relay 18 is normally open, and the other fixed contact is connected to the anode (+B) of the vehicle battery.

Furthermore, one end of the coil of the trunk lid opener relay 18 is grounded, and
The other end is connected to one fixed contact of a trunk lid open cancel relay 19 that constitutes a second relay in this embodiment. The trunk lid open cancel relay 19 is normally closed, and the other fixed contact is connected to the +ACC terminal of the ignition key via a normally open trunk lid opener switch 20, which is an operation switch.

The coil of the trunk lid open cancel relay 19 has one end connected to the anode (
+B), and the other end is grounded via the top storage lid state detection switch 21. The top storage lid state detection switch 21 is configured to detect the top storage lid 5.
It is turned off when the switch is in the closed state, and turned on in response to this when the switch is in any open state other than the closed state.

In this embodiment having the above configuration, when both the top storage lid 5 and the trunk lid 6 are in the closed state, the top storage lid state detection switch 21 and the trunk lid state detection switch 15 are both turned off. It becomes. Therefore, the coil of the top storage lid open cancel relay 13 is in a non-excited state, and the movable contact of the top storage lid open cancel relay 13 is turned on. Further, the coil of the trunk lid open cancel relay 19 is also in a non-energized state, and the movable contact of the trunk lid open cancel relay 19 is also turned on.

Therefore, when the top storage lid opener switch 14 is turned on in this state, the coil of the top storage lid opener relay 12 is excited, and the movable contact of the top storage lid opener relay 12 is turned on. As a result, the hood storage lid actuator 10 operates,
The hood storage lid 5 is driven in the opening direction.

Then, when the top storage lid 5 is opened appropriately, if the top storage lid opener switch 14 is turned off, the coil of the top storage lid opener relay 12 is de-energized, and the top storage lid is opened. The movable contact of the lid opener relay 12 is turned off. Therefore, the top storage lid 5 stops when the top storage lid opener switch 14 is turned off, and maintains the open state.

At this time, when the top storage lid actuator 10 starts operating and the top storage lid 5 changes from the closed state to the open state, the top storage lid state detection switch 21 is turned on at that point. Then, the coil of the trunk lid open cancel relay 19 is excited, and the movable contact of the trunk lid open cancel relay 19 is driven off, thereby cutting off the power supply circuit 17. Therefore, even if the trunk lid opener switch 20 is turned on in this state, the coil of the trunk lid opener relay 18 will not be energized, the movable contact of the trunk lid opener relay 18 will remain in the OFF state, and the trunk lid opener switch 20 will not be energized. The lid actuator 16 is maintained in a stopped state. As a result, both lids 5
, 6 are prevented from opening simultaneously, and interference between the lids 5 and 6 and damage caused by the interference can be avoided.

[0021] Also, the top storage lid 5 and the trunk lid 6
When the trunk lid opener switch 20 is turned on while both are closed, the coil of the trunk lid opener relay 18 is energized, and the movable contact of the trunk lid opener relay 18 is turned on. As a result, the trunk lid actuator 16 operates, and the trunk lid 6 is driven in the opening direction. When the trunk lid 6 is opened appropriately, if the trunk lid opener switch 20 is turned off, the coil of the trunk lid opener relay 18 is de-energized, and the movable contact of the trunk lid opener relay 18 is turned off. is turned off. Therefore, the trunk lid 6 stops when the trunk lid opener switch 20 is turned off and remains open.

At this time, when the trunk lid actuator 16 starts operating and the trunk lid 6 changes from the closed state to the open state, the trunk lid state detection switch 15 is turned on at that point. Then, the coil of the hood storage lid open cancel relay 13 is energized, and the hood storage lid open cancel relay 13 is energized.
The movable contact of is driven off, which causes the power supply circuit 11
is blocked. Therefore, even if the top storage lid opener switch 14 is turned on in this state, the coil of the top storage lid opener relay 12 will not be energized and the movable contact of the top storage lid opener relay 12 will not be turned on, and the top storage lid opener switch 14 will not be turned on. The storage lid actuator 10 is maintained in a stopped state. This prevents both lids 5 and 6 from being opened at the same time, thereby preventing interference between the lids 5 and 6 and damage caused by the interference.

Therefore, since simultaneous opening of both lids 5 and 6 can be prevented by an electric circuit without using the mechanical link 8 shown in FIG.
There is no need to secure a space necessary for the existence of the link 8 itself or a space necessary for the link 8 to operate in the hood storage section 2 and the trunk room 3. Therefore, it is possible to eliminate the inconvenience that the storage space of the top storage section 2 and the trunk room 3 is significantly reduced, and as a result, the storage space of the top storage section 2 and the trunk room 3 cannot be increased due to the vehicle body layout like in a convertible car. Even in the vehicle, it is possible to secure as much storage space as possible for the hood storage section 2 and the trunk room 3.

Further, harnesses for forming each of the power supply circuits 11 and 17 are connected to the top storage section 2 and the trunk room 3.
Since it is possible to embed it in the trim arranged inside the bulkhead 9, there is no need to provide a through hole H (see FIG. 4) in the bulkhead 9, and it is also possible to ensure airtightness in the trunk room 3. It becomes.

[0025]

As explained above, the present invention drives the top storage lid and trunk lid open by electric drive means, and when one lid is in the open state, the other lid is opened. The power supply circuit of the electric drive means to be driven is cut off. Therefore, without using a mechanical link, it is possible to prevent the top storage lid and the trunk lid from being opened simultaneously and to prevent interference between the two lids. As a result, the need to provide space necessary for the existence of the link itself and space necessary for the operation of the link in the top storage section and the trunk room is eliminated,
Even in a vehicle where the accommodating space for the hood storage section and the trunk room cannot be increased due to the vehicle body layout, the accommodating space for the hood storage section and the trunk room can be secured as much as possible.

[0026] Furthermore, since it is no longer necessary to provide a through hole for a link that connects to both lids in the bulkhead that partitions the top storage area and the trunk room, it is also possible to ensure the airtightness of the trunk room. .
