Description

  The present invention relates to an emergency mechanism, and more particularly to an emergency mechanism in which a lid is opened / closed by using an emergency member, and the lid is opened / closed by applying an external force to the lid by disconnecting the motor from the motor. It is.

  Conventionally, various studies have been made on vehicles having a retractable roof whose front roof and back roof are movable. Such a vehicle is stored in a storage space at the rear of the vehicle with the two roofs folded when the front roof covering the upper part of the passenger compartment and the back roof covering the rear of the passenger compartment are open. Is done. On the other hand, when the outside air temperature is low or raining, the two roofs are closed to cover the entire upper part of the vehicle compartment, and the vehicle compartment is sealed.

Such a retractable roof opening / closing mechanism is disclosed in, for example, Patent Document 1 and the like, and generally a four-bar linkage mechanism is used. Further, the lid of the roof storage space is opened and closed by an opening / closing mechanism provided separately. Conventionally, many hydraulic cylinders have been used as the drive source for the open / close mechanism. However, since hydraulic cylinders have a lot of energy loss such as excess pump loss, system mass loss, and control valve excess fluid loss, recently electric motors Has come to be used. In Patent Document 1, a hydraulic cylinder is used for the opening / closing mechanism of the roof, and it is not specified what is used for opening / closing the lid (tail plate) of the storage space.
JP-A-8-244465

In a vehicle equipped with the retractable roof described above, it is conceivable that the drive source of the opening / closing mechanism fails and does not move. In such a case, for example, assuming that the roof is opened and stored in the storage space, the roof does not close even if it rains, so that the passenger and the passenger compartment get wet. Therefore, in preparation for such an emergency situation, it is necessary to install an emergency mechanism in the vehicle that allows an occupant to manually open and close the roof. Especially in the open state, the storage space must first be opened manually. If a hydraulic cylinder is used as the drive source, the lid and roof can be moved manually by releasing the hydraulic pressure by some means and releasing the latch. However, in the case of motor drive, there is a hole in the motor itself. An emergency mechanism that rotates the drive shaft by inserting a wrench into the door has traditionally been used, but with this, the vehicle owner cannot handle when the lid closes and the opening and closing mechanism breaks down. Until then, there was a problem that the passenger compartment became rainy.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an emergency mechanism that can easily open and close the lid by an external force such as human power in a lid opening and closing mechanism in which the motor is a driving source. Is to provide.

  In order to solve the above problems, the emergency mechanism of the present invention is used in a link mechanism that opens and closes a lid using a motor as a drive source. The emergency mechanism disconnects the link mechanism and the motor, and the lid An emergency mechanism that allows the lid to open and close by applying an external force to the base, wherein the link mechanism includes a base, a driving lever having one end pivotally connected to the base, and the other of the driving lever. A lid connected to an end, and the driving lever is driven via a pinion by a gear driven by the motor, and the gear is rotatably attached to the base, and the motor is a motor It is fixed to the bracket and attached to the base via the motor bracket. A hole and a long hole are provided, and the motor bracket is attached to the base by a rod member inserted into each of the hole and the long hole, and the motor bracket is attached to the motor by the emergency member. The motor is rotated in a direction perpendicular to the motor drive shaft, with the central axis extending in the through-penetration direction of the hole as a rotation axis, and the gear and the pinion It has a configuration in which the meshing is disengaged. Here, the lid is a panel member that covers the upper surface of the room and opens and closes the room space, for example, a movable roof that becomes the ceiling of the passenger compartment, a trunk lid of the trunk room, a cover of a storage space that houses the retractable roof, etc. Can be mentioned. The movement of the motor bracket by the emergency member includes both the case where the emergency member pushes and moves the motor bracket and the case where the emergency member is coupled to the motor bracket by screwing, fitting or the like and pulls and moves the motor bracket. . Making the lid openable / closable by applying an external force to the lid means that the lid can be opened / closed by applying a force to the lid by a driving source other than a motor that drives the link mechanism.

  With the above-described configuration, the connection between the motor drive shaft and the link mechanism, that is, so-called edge cutting can be performed by a simple mechanism and a simple method. Therefore, the lid can be opened and closed without rotating the drive shaft of the motor.

  When the motor rotates about a central axis extending in the through direction of the hole as a rotation axis, the rod member inserted into the long hole passes through the long hole in a direction perpendicular to the through direction of the long hole. A configuration that moves is preferable.

  The base is provided with an emergency hole penetrating in a direction perpendicular to the drive shaft of the motor, and the emergency member is inserted into the emergency hole and comes into contact with the motor bracket so that the motor bracket It is preferable that it is the structure which moves.

  Preferably, the emergency member is a bolt, and the emergency hole is formed with a female screw.

  The rod member is preferably a bolt or a pin, and at least a part of the washer used for the rod member is preferably made of resin.

  It is preferable that one of the bolts used for mounting the base and the motor bracket is removed and used as the emergency member.

  By moving the motor bracket in the direction perpendicular to the motor drive shaft by the emergency member, the motor rotates in the direction perpendicular to the motor drive shaft and the meshing between the gear and the pinion is disengaged, so the motor stops. The lid can be easily opened and closed by external force such as human power.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following drawings, components having substantially the same function are denoted by the same reference numerals for the sake of brevity.

(Embodiment 1)
FIGS. 1 and 2 are schematic side views showing a traveling vehicle (passenger automobile) 1 having a retractable roof 5.

  The retractable roof 5 includes a front roof 2 serving as a ceiling of the crew room, a back roof 3 and a rear window 4 on the rear side of the crew room, and the front roof 2, the back roof 3, and the rear window in the fully opened state shown in FIG. 4 is folded and stored in the storage space 7. In FIG. 1, a state in which the retractable roof 5 is fully closed is indicated by a solid line, and a half-open (half-closed) state is indicated by a one-dot chain line. When the retractable roof 5 is fully opened and fully closed, the storage space 7 is shielded by the lid 6. The retractable roof 5 and the lid 6 are opened and closed by a link mechanism. However, if the link mechanism is drawn in the drawing, the drawing becomes complicated and difficult to see, so the link mechanism is not shown in FIGS.

  3 and 4 are diagrams showing a link mechanism for opening and closing the lid 6. FIG. 3 is a view showing a state where the lid 6 is closed and the pinion 22 of the motor 12 and the sector gear 13 driving the link are engaged with each other, and FIG. 4 is an illustration of the disengagement between the pinion 22 and the sector gear 13. The lid 6 is a state in which it is slightly opened. FIG. 6 shows a state where the lid 6 is completely opened. In these drawings, the lid 6 is indicated by a one-dot chain line for easy understanding of the link mechanism, and the motor 12 and the motor bracket 11 are omitted in FIG.

  This link mechanism is a mechanism that opens and closes the lid 6 using the motor 12 as a drive source. Both ends of the main bracket 21 that is a base, the lid bracket 31 fixed to the lid 6, the main bracket 21 and the lid bracket 31 are pivoted. A driving lever 14 that is connected to support the link mechanism and a driven lever 15 that is pivotally connected to both ends of the main bracket 21 and the lid bracket 31 to restrict the opening / closing range and opening / closing movement of the lid 6. Yes. The main bracket 21 is fixed to the vehicle body by being fixed to the bottom surface of the storage space 7. In the present embodiment, the lid 6 and the lid bracket 31 can be collectively referred to as a lid.

  Hereinafter, the structure of the link mechanism will be described with reference to FIG.

  In this link mechanism, the driving lever 14 is driven by the sector gear 13. A pin attached to the sector gear 13 is fitted into the long hole 34 of the long hole cam 33 attached to the driving lever 14, and the pin moves in the long hole 34 as the sector gear 13 rotates, and the long hole 34 The driving lever 14 is driven by applying a force to the inner wall. The sector gear 13 is rotatably attached to a main bracket 21 as a base by a sector gear mounting bolt 41 and is driven by the motor 12 via a pinion 22 (hidden on the back side of the motor 12 in FIG. 5). . That is, the sector gear mounting bolt 41 serves as the rotation shaft of the sector gear 13.

  The motor 12 is fixed to the motor bracket 11, and the motor bracket 11 is attached to the main bracket 21 by two bolts (rod members) 42 and 43. Among these bolts 42 and 43, the bolt 42 is inserted into a hole 45 formed in the motor bracket 11, and the bolt 43 is inserted into a long hole 46 formed in the motor bracket 11. A resin washer 51 is sandwiched between the inner screw 21 and a female screw hole formed in the main bracket 21. Further, the main bracket 21 is provided with a bent portion 52 that is bent from a surface to which the motor bracket 11 is attached and extends substantially perpendicularly to the surface, and an attachment hole 53 opened in the bent portion 52 is provided. An emergency bolt 44 which is an emergency member is inserted and screwed into the motor bracket 11 to be fixed. Further, an emergency hole 54 described later is provided in the bent portion 52 on the mounting hole 52. The emergency hole 54 is formed with a female screw that can be screwed into the emergency bolt 44.

  As shown in FIG. 3, when the lid 6 is closed, the hook portion 23 provided on the sector gear 13 engages with the hook engaging pin 32 provided on the lid bracket 31 fixed to the lid 6. Locking is performed so that the lid 6 does not open. The hook portion 23 is formed by forming one gear end portion of the sector gear 13 in a hook shape.

  Here, consider the case where the motor 12 fails and does not operate (stop of the motor 12). When the retractable roof 5 is stored in the storage space 7 in the fully opened state and the lid 6 covers the storage space 7, the retractable roof 5 cannot be closed when it rains. There is a risk that various instruments will get wet and break down. In this case, since the sector gear 13 and the pinion 22 mesh with each other, the sector gear 13 does not move unless the motor shaft rotates. If an attempt is made to rotate a motor shaft that does not operate by forcibly moving the sector gear 13 from the outside, a very large force is required and the link mechanism is broken. In this case, since it is impossible to rotate the motor shaft by human power, it is necessary to request a specialized repair shop to rotate the motor shaft.

  However, since the emergency mechanism is provided in the link mechanism of the present embodiment, the lid 6 can be manually opened even if the motor 12 stops operating. The emergency mechanism according to this embodiment will be described below.

  In the present embodiment, as shown in FIG. 3, when the lid 6 covers and closes the storage space 7, the motor 12 is stopped and the sector gear 13 and the pinion 22 are engaged with each other as described above. The lid 6 cannot be opened unless the motor shaft connected to the pinion 22 is forcibly moved. In order to be able to manually open the lid 6 in this state, the emergency bolt 44 is first removed by releasing the screwing with the motor bracket 11. Then, an emergency bolt 44 is screwed into and screwed into an emergency hole 54 provided in the bent portion 52.

  Since the emergency hole 54 is a through-hole, when the emergency bolt 44 is further screwed in, the tip of the emergency bolt 44 penetrates the bent portion 52 and comes into contact with the contact surface 47 of the motor bracket 11, so that the motor bracket 11 is attached to the motor 12. Push in a direction perpendicular to the drive axis. The motor bracket 11 is attached to the main bracket 21 by two bolts 42 and 43, and this attachment is performed via resin washers 51 and 51, and the bolt 43 is a long hole of the motor bracket 11. 46, the motor bracket 11 rotates about the bolt 42 as the rotation axis. At this time, the washers 51 and 51 are made of resin, so that the motor bracket 11 can be rotated by being deformed. Here, the motor bracket 11 rotates in a direction perpendicular to the motor 12 drive shaft.

  Since the long hole 46 is formed so as to extend on the same arc centering on the hole 45 into which the bolt 42 is inserted, the contact surface 47 is pushed by the emergency bolt 44 and the motor bracket 11 rotates. As it goes on, the bolt 43 remains fixed, but the long hole 46 changes its position with respect to the bolt 43. The rotation of the motor bracket 11 by being pushed by the emergency bolt 44 is such that in FIG. 3, the upper side of the bolt 42 rotates in the right direction and the lower side rotates in the left direction.

  Thus, when the motor bracket 11 rotates, the motor 12 fixed to the motor bracket 11 also rotates together. This rotation causes the pinion 22 to move away from the sector gear 13 and disengage them from each other.

  To disengage the pinion 22 and the sector gear 13, the pinion 22 may be moved by the length of the tooth. In the present embodiment, the distance from the bolt 42 serving as the rotation axis of the motor bracket 11 to the pinion 22 axis and the distance from the bolt 42 to the contact surface 47 are substantially the same. If the 47 is moved by a distance corresponding to the length of the teeth of the pinion 22, the meshing is released. When the engagement is released, the sector gear 13 is operated with a rod-shaped member to remove the hook portion 23 from the engagement pin 32. Here, the hook portion 23 of the sector gear 13 is pushed and removed by a rod-like member, but the hook portion 23 is hooked and pulled from the right side of the drawing by a rod-like member provided with a flange portion at the tip, and the engagement with the engagement pin 32 is released. May be. When the engagement between the hook portion 23 and the engagement pin 32 is released, the lid 6 can be lifted manually. FIG. 4 shows a state where the lid 6 is slightly lifted.

  The operation of the emergency mechanism described so far is performed by providing a hole or a gap in the partition between the crew cabin and the storage space 7. For example, when a hole is provided in the partition, a tool or a hand is inserted into the storage space 7 from the hole to operate the emergency bolt 44, and the hook portion 23 and the engagement pin 32 are disengaged with a rod-shaped member. Perform the operation.

  As described above, in the present embodiment, the engagement between the pinion 22 and the sector gear 13 can be removed by a simple operation of removing the emergency bolt 44 from the main bracket 21 and screwing it into the emergency hole 45. Even a person unskilled in repair can work easily and can work in a short time. Further, since a large force is not necessary for screwing the emergency bolt 44 into the emergency hole 45, even a person with a weak force can work. After the motor is repaired, the emergency bolt 44 can be easily removed from the emergency hole 45, inserted into the original mounting hole 53, and screwed into the main bracket 21 to easily return to the original state before the repair. This emergency mechanism can be constructed simply by providing the emergency hole 45 and the long hole 46 in the link mechanism that does not have the emergency mechanism and making the washers 51, 51 made of resin, so that the manufacturing cost can be kept low. Since only a few changes are required, there is almost no new design cost.

(Embodiment 2)
The link mechanism according to the second embodiment is obtained by removing the hook portion 23 and the engagement pin 32 from the link mechanism of the first embodiment. That is, the sector gear 13 of the present embodiment is not formed with a hook portion, and the lid bracket 31 is not provided with an engagement pin. Since the other configuration is the same as that of the first embodiment, the illustration of the link mechanism of the present embodiment is omitted.

  The link mechanism and emergency mechanism of the present embodiment do not have a lock mechanism for the cover 6 when the cover 6 is fully closed. If the mechanism is provided, the closed state of the lid 6 is reliably maintained. In the present embodiment, the same effects as those of the first embodiment are obtained except for the effects related to the lock mechanism of the lid 6. Further, in the present embodiment, in addition to the effects of the first embodiment, it is not necessary to disengage the hook portion and the engagement pin after disengaging the pinion 22 and the sector gear 13, so that the lid 6 can be removed immediately. It can be lifted by hand, and the emergency operation can be performed more easily than in the first embodiment.

  In the above embodiment, the pinion 22 and the sector gear 13 are disengaged by moving the motor 12, but the pinion 22 and the sector gear 13 are disengaged by moving the sector gear 13 side. It does not matter as a mechanism. Further, an idle gear may be inserted between the pinion 22 and the sector gear 13. In this case, the engagement between the pinion 22 and the sector gear 13 may be released by moving the idle gear. Further, the motor 12, the sector gear 13, and the idle gear may be moved in a direction horizontal to the motor drive shaft to disengage the pinion 22 from the sector gear 13. Further, in the above case including the embodiment, a normal gear may be used instead of the sector gear 13.

  The emergency member that moves the motor 12 is not limited to a bolt. It may be a simple rod-shaped member that moves the motor bracket 11 by pushing it, or it is a hook-shaped member that engages with a part of the motor bracket 11 and pushes or pulls the motor bracket 11 to move. It doesn't matter. That is, the emergency member may be of any shape as long as it can move the motor bracket 11 by abutting, engaging, fitting, etc. with the motor bracket 11.

  In the above embodiment, the motor bracket 11 is pushed and moved by the emergency bolt 44. However, an emergency screw hole is provided in the motor bracket 11, and the emergency bolt 44 is screwed there, that is, the motor bracket 11 is mounted. The motor bracket 11 may be moved by pulling.

  In the lid link mechanism, the driven lever 15 may be omitted. In this case, one end of the driving lever 14 is connected to the lid, and the other end of the driving lever 14 is pivotally connected to the base.

  The operation of the emergency mechanism is not limited to being performed from the crew room side, but may be performed from the rear side (for example, trunk), the lower side, or the side of the storage space.

  The lid is not limited to the lid, and may be a roof or a rear window. The external force applied to the lid after the emergency mechanism is activated is not limited to human power, and mechanical force may be used.

  The washer used for attaching the motor bracket to the base is not limited to a resin washer partly or entirely, and the emergency member (bolt) is deformed when the motor bracket is moved, and the motor bracket can be easily moved. Any material washer may be used. Further, the motor bracket may be attached to the base using a pin instead of a bolt.

  As described above, since the emergency mechanism according to the present invention has a simple structure and can easily disengage the pinion and the gear, it is useful as an emergency mechanism for the lid opening / closing mechanism of the vehicle.
