DE4445580 DE4445944

  An object of the present invention is to solve the above problems and provide an improved trunk door device.

  It is another object of the present invention to provide a vehicle equipped with an improved trunk door device.

The invention will now be described, by way of example only, with reference to the accompanying drawings. In these diagrams:
FIG. 1 is a side view of a trunk door device having a hinge according to the present invention;
2 and 3 are illustrations of the trunk device in response to various conditions during the transition of the trunk door from the closed position to the standard first position;
4 and 5 are diagrams of the trunk device according to various states during the transition of the trunk door from the closed position to the second position.

  Referring to these figures, the vehicle has a retractable roof 110. In order to clarify the following description, two terminal positions of the roof 110 are defined.

  When the panel of the roof 110 is supported on the vehicle frame, in particular the upper column of the windshield, that is, the roof 110 serves as the roof of the passenger compartment formed by the driver's seat and the passenger's seat as a whole. The roof 110 is said to be in the closed position when

  The entire roof 110 is housed in a storage space allocated at the rear of the vehicle, so that the roof 110 is uncovered when the vehicle compartment formed by the entire driver seat and passenger seat is uncovered. Is said to be in the retracted position.

  In the configuration with the roof 110 in the closed position, the rear cover structure is located behind the safety arch (rollover bar). Advantageously, the rear cover structure has a generally horizontal rear transverse plate. Arms for supporting the roof 110 are deployed on both sides of the rear lateral plate in the lateral direction of the vehicle. In the folded position, the rear transverse plate is likewise located after the generally horizontal safety arch. From this time, the arm connected to the roof 110 is accommodated in a storage space allocated to the roof 110 at the rear of the vehicle. For this reason, in order to cover the space opened from the arm connected to the roof 110, “flaps” called shutters for closing are opened from the storage position on both sides of the rear horizontal plate in the lateral direction of the vehicle. Moved to an unfolded position that allows the covered space to be covered. The presence of such a shutter is because the vehicle in the position where the roof 110 is folded from the aesthetic point of view presents a flat surface, and from the aerodynamic point of view to avoid air flow disturbance, Necessary for the waterproofing of the existing mechanism.

  In order to allow the retraction of the roof 110 into the storage space at the rear of the vehicle, the rear transverse plate changes position, referred to as the rest position, preferably from the generally horizontal initial position, referred to as the open position, In order to provide a place for the roof 110 to pass through, it is preferably moved sequentially to a generally vertical position. Thereafter, the lateral plate finally returns to a generally horizontal position.

  When the roof 110 is in the closed or retracted position, the rear transverse plate advantageously has an angle with a horizontal plane such that the rear of the transverse plate is lower than the front of the transverse plate. .

The movement of the rear lateral plate during the retraction of the roof 110 is developed as follows:
In the closed position, the rear part of the generally horizontal transverse plate is sandwiched by the rear part of the roof 110. When the driver commands the opening of the roof 110, the control device operates the first movement of the trunk door 112 to open the storage space allocated to the roof 110 at the rear of the vehicle. The roof 110 is moved by the hydraulic action of the control jack while the trunk door 112 continues to turn about the lateral axis of the vehicle toward the rear of the vehicle. The rotational movement of the roof 110 causes the rotational movement of the horizontal plate via the cam device. In order to allow the rear lateral plate to be released from being clamped by the roof 110, the rear lateral plate performs a first rotational movement about the lateral axis of the vehicle towards the lower side of the vehicle. When the rear portion of the roof 110, which has been previously clamped by the horizontal plate, is positioned below the vertical height of the horizontal plate, the horizontal plate is positioned on the top of the vehicle around the vehicle's horizontal axis. A second rotational movement towards is performed. This second rotational movement is performed until the transverse plate is supported in a generally vertical position. While the transverse plate is in this support position, the roof 110 continues its retraction into the assigned storage location, after which the rotation of the closing shutter is interlocked.

  The folding of the transverse plate is then operated by closing the trunk door 112. For example, a mechanical cable of the type of a bicycle brake cable, known under the name Bowden cable, transmits the force provided by the closing mechanism of the trunk door 112 to the device connected to the transverse plate. When the closing of the trunk door 112 is being operated by the control device, i.e. when the entire roof 110 has not yet been retracted, the rear transverse plate now with two closing shutters is added. To return to the horizontal position, the simultaneous movement of the rear transverse plate is brought about by the connection by cables.

  The movement of the rear lateral plate that enables the transition of the roof 110 from the retracted position to the closed position is symmetrically identical to the movement from the closed position to the retracted position. Initially, the transverse plate is supported in a generally vertical position and then returned to a generally horizontal position. This movement is caused by the action of the Bowden cable which transmits the movement of the trunk door 112 back to the closed position and the movement of the trunk door 112 to the transverse plate.

As seen above, when the roof 110 is in the retracted position, it is necessary to have closing shutters on both sides of the lateral plate for aesthetic, aerodynamic and waterproof requirements. When the roof 110 is in the closed position, these closing shutters cannot be in this position because they prevent passage of the arms attached to the roof 110. When in the closed position, the shutter is slid under the rear lateral plate. The principle of shutter movement is as follows:
When the roof 110 is in the closed position and when the roof 110 is started to rotate, the shutter remains slid under the lateral plate. The shutter remains slid into this position until the transverse plate is supported in a generally vertical position. In this position, rotation of the roof 110 about the horizontal axis of the vehicle results in movement of the shutter via the cam. To move from the slipped position under the horizontal plate to the horizontal position of the horizontal plate that forms a plane with the horizontal plate, the movement of the shutter is the same as the discharge movement from under the horizontal plate and the horizontal plate. Translation to reach height needs to be done at once. These two movements are advantageously carried out simultaneously by helical rotation. It will be appreciated that these two movements can be performed sequentially by a rotational movement followed by a translation or two translations.

  The respective movements of the closing shutter and the transverse plate are caused by a common mechanism of rotation based on the initial rotational movement of the roof 110.

  The continuous rotational movement of the roof 110 results in two successive movements, the first lateral plate movement and the next closing shutter movement. Due to the symmetry with respect to the central axis of the vehicle, the mechanism described below for the left side of the vehicle is the same for the right side of the vehicle.

  The continuous rotational movement of the roof 110 is caused by hydraulic control. The end of the body from which the piston emerges from the jack (actuator) composed of the body and the piston is articulated to the vehicle body 100. Such a joint connection allows the movement of the body of the jack without causing a significant penalty for the longitudinal pushing force of the piston. This movement of the piston causes the movement of two connecting rods, each connected to the free end of the piston. The first connecting rod is connected to the vehicle body 100, and simultaneously ensures the movement of the piston and the stability when the piston is extended. A second connecting rod, called a speed reducing connecting rod, is rotatably mounted on an inner arm of the roof 110 that supports the roof 110 located opposite the passenger compartment, and transmits the translational movement of the piston to the inner arm. Then, it converts into the rotational motion of the inner arm. The deceleration connecting rod, which is the second connecting rod, pulls the inner arm toward the jack when the piston is retracted, and conversely pushes the inner arm when the piston extends outside the body. The lower part of the inner arm is rotatably mounted about a fixed axis called the main axis of rotation, so the movement of the inner arm is a rotational movement around this axis. Various nodes consisting of all of the nodes specifically formed by the rotation axis, that is, the nodes between the structure of the roof 110 and the upper portions of the inner and outer arms and the nodes between the outer arms and the vehicle body 100. The whole forms a quadrilateral with a smooth structure. This quadrilateral movement is caused by the rotation of the inner arm around the main axis of rotation. Thus, the movement of the roof 110 supported by the quadrilateral of the striated structure is caused by the generally longitudinal movement of the piston and is performed via rotation about the main axis of rotation.

  The main rotation shaft has at least one first pulley having a protrusion perpendicular to the rotation shaft and a surrounding groove. The main rotation shaft has at least one cam having a radial protrusion. The tip of the inner arm extends inward of the vehicle in parallel with the main rotational axis. The relative positions of the various parts supported by the main rotating shaft are: the inner arm is located outside the vehicle, the cam is located inside the vehicle, and the first pulley is located between the inner arm and the cam. Try to be in between. Therefore, the extension part of the inner arm parallel to the main rotation axis crosses the rotation surface of the first pulley, and the protrusion of the first pulley contacts the extension part of the inner arm parallel to the main rotation axis. Has a possible size.

  One end of a generally “L-shaped” lever is articulated to one of the cam tips, and the lever has an opening that allows the end of the cam's radial projection to pass through. The other end of the lever is attached so as to be rotatable around an axis that works with the horizontal plate.

  A second pulley is rotatably mounted around a second rotation shaft supported by the cover member. This cover member also supports the main rotating shaft. This second pulley has a groove into which a mechanical cable of the bicycle brake cable type is inserted. This cable is connected to a mechanism that opens the trunk door 112.

  The cam is connected to one end of the return spring, and the other end of the return spring is attached to the cover member. The return spring generally pushes the lateral plate through the cam and the “L-shaped” lever when the second pulley, which blocks the cam radial protrusion, is driven by the trunk door cable. Acts to return to a horizontal position. At this time, the cam is released and comes into contact again with the extending portion of the inner arm by the action of the return spring.

  The extension portion of the inner arm has first and second surfaces suitable for cooperating simultaneously with the third surface of the first pulley protrusion and the fourth surface of the cam. These third and fourth surfaces are parallel to the surfaces defined by the first and second surfaces of the extension of the inner arm in the rest position when the transverse plate is lowered and the roof 110 is closed. Arranged so that it is not in-plane. In this way, the cam is displaced relative to the first pulley in the rest position. As a result, when the roof 110 is stowed, and therefore the inner arm is rotated, the second surface of the inner arm extension first comes into contact with the fourth surface of the cam and the main rotation of the cam. Causes rotation around the axis. This rotation of the cam on the one hand results in the movement of the “L-shaped” lever and thus the lateral plate to the vertical position, on the other hand in the radial direction of the cam which is now engaged in the groove of the second pulley. This causes movement of the protrusion.

  While the roof 110 continues to be stowed, i.e., continues to rotate about the main axis of rotation of the inner arm, the first side of the extension of the inner arm is now the third of the first pulley. It comes into contact with the surface and causes a rotation around the main rotation axis of the first pulley. A bicycle brake cable type cable is mounted in the groove of the first pulley, and the rotation of the first pulley generates a pulling force on the cable. This pulling force acts on the operating mechanism of the closing shutter at the other end of the cable. The closing shutter operating mechanism is attached to a horizontal plate, and includes a shaft that interlocks with the horizontal plate and a cylinder that supports the closing shutter. This movement with respect to the axis of the cylinder is a helical rotational movement which allows the shutter to be ejected from below the horizontal plate and at the same time allows the shutter to return to approximately the same height as the horizontal plate. Therefore, the helical rotary motion of the closing shutter is started by the rotation of the first pulley supported on the main rotary shaft.

  It will be appreciated that the movement of the closing shutter begins during the storage of the roof 110 when the transverse plate is in a generally vertical position. This shutter movement ends when the roof 110 is already retracted and the trunk door 112 is returned to its initial position. When the assembly of the first pulley, the intermediate support member, and the cam is supported by the extending portion of the inner arm, the position of the rear lateral plate is adjusted by moving the trunk door 112. Return starts. A cable connects the mechanism of the trunk door 112 to the second pulley and allows the second pulley to rotate, thereby disengaging the cam radial protrusion. The cam and thus the “L-shaped” lever can be moved, allowing the horizontal plate to return to a generally horizontal position. The horizontal plate is supported in contact with a stopper interlocked with the cover, and reaches the substantially horizontal position.

  When the driver places the roof 110 in the closed position, the operation is similarly developed symmetrically. The opening of the trunk door 112 and the movement of the gliding device that supports the roof 110 cause the rear transverse plate to move to a generally vertical position, and the third surface of the first pulley and the cam first. On the surface of 4, the disengagement achieved by the first and second surfaces of the extension of the inner arm is caused. The spring device provided between the shaft and the cylinder used for the helical rotation of the closing shutter no longer exists when there is no tension applied to the cylinder by the cable, i.e. the first pulley rotates the main rotation shaft. When opened as a result, the shutter can be returned to a position below the transverse plate to allow the passage of the arm supporting the structure of the roof 110.

  The position at which the gliding device supports the roof 110 and the roof 110 is closed has a lower portion below the vehicle body structure and an upper portion connected to the roof 110 and thus above the vehicle body structure. In addition, the retracting position of the roof 110 where the sliding device is located completely below the vehicle body structure is based on the premise that an opening is provided in the vehicle body structure in order to allow passage of the sliding device. This opening cannot be exposed when the roof 110 is in the retracted position for aesthetic, aerodynamic, and waterproof reasons. Advantageously, the inner arm that supports the roof 110 has an elbow shape proximate its lower end. This elbow shape complements a cam specific to a hatch (not shown) located in the vehicle structure in a region quite close to the transverse plate. When the roof 110 is driven back to the closed position, the lower part of the inner arm contacts the hatch cam, causing rotation of the cam and the plate integrated with the cam, and hence the opening of the hatch. At that time, the inner arm and the outer arm can pass through this hatch to support the roof 110. When the roof 110 is retracted, and therefore when the lower part of the inner arm is no longer in contact with the cam, the cam returns to the rest position and closes the hatch by rotation of a plate integrated with the cam in the rest position. For this purpose, a return spring is connected to the hatch cam.

  The present invention also relates to the mechanism of the trunk door 112. A vehicle in which a rigid roof 110 can be retracted into a storage space assigned to the rear of the vehicle needs to have a trunk door 112 for special movement.

  First, the trunk door 112 needs to allow a standard opening to accommodate luggage into the trunk. For this reason, when the trunk door 112 is in the closed position, the foremost portion of the trunk door 112 is mounted for rotation about a lateral axis. Thus, access to the trunk is from the rear of the vehicle when the trunk door 112 is open.

  Second, when the driver wishes to retract the roof 110, the roof 110 will be housed in a storage space allocated within the trunk area. Thus, the trunk door 112 needs to be opened to allow the roof 110 to pass through, but a standard opening does not allow this. Accordingly, when the trunk door 112 is in the closed position, the rearmost portion of the trunk door 112 needs to rotate about the second lateral axis. Thus, access to the trunk occurs from the front of the vehicle when the trunk door 112 is open, thus allowing the roof 110 and associated mechanisms to pass through.

  The trunk door 112 is an assembly of three main parts: a locking device having a hinge 118 called a “gooseneck” and two lateral mechanisms symmetrically arranged on each side of the trunk door 112. Moved. Since the left and right lateral mechanisms are symmetrical, only the left lateral mechanism will be described.

  The lateral mechanism includes a plate 122 coupled to the vehicle body 100, an intermediate frame 116 articulated to the plate 122, one end attached to the plate 122, and the other end coupled to the intermediate frame 116. It is located between the 1 pneumatic device 120, the intermediate frame 116 and the trunk door 112, and is composed of a sliding device made of a rod and a second pneumatic device. The plate 122 is provided on the same part with an articulated connection of the intermediate frame 116, immobilization means for providing the possibility of locking the frame in an ascending position, and a first for operating the movement of the intermediate frame 116. Various functions such as fixing the pneumatic device 120 can be combined. The plate 122 is made of a lightweight material, has a small thickness, and preferably has a triangular shape.

  The intermediate frame 116 is composed of a single part having a generally “double L” shape. A first portion called a hinge portion (first hinge portion) is attached to the plate 122 via a joint connection that is generally in the lateral direction of the vehicle and along an axis orthogonal to the plate 122. This first hinge also supports the free end of the first pneumatic device 120, and the translational movement of the piston of the first pneumatic device 120 is due to this rotational free connection and the nodal point on the frame plate 122. It causes a rotational movement of the intermediate frame 116 about an axis along the transverse direction and perpendicular to the plane of the plate 122. The intermediate frame 116 has a first elbow portion, and the first elbow portion connects the first hinge portion to one end of a second portion (second transmission portion) called a transmission portion. The second transmission portion and the first hinge portion are substantially perpendicular. At the other end of the second transmission part, the second elbow part is extended by a third part (third support part) generally parallel to the first hinge part, which is called a support part. The third support portion has various nodes. At these nodes, various rods of the gliding device are attached, which are located between the third support part of the intermediate frame 116 and the support plate connected to the trunk door 112. The free end of the second pneumatic device is also attached to the third support portion of the intermediate frame, and the body of the jack of the second pneumatic device is connected to a support plate connected to the trunk door 112.

  When the trunk door 112 is opened as in the prior art for handling luggage, the second pneumatic device that is compressed when the trunk door 112 is closed unlocks the trunk door 112. It grows immediately. Thus, the stroke of the piston causes the trunk door 112 to open, accompanied by the rod of the gliding device connected to the third support of the intermediate frame 116. In such opening of the door, the intermediate frame 116 remains fixed with respect to the plate 122 without being moved by the action of the immobilization means attached to the plate 122. For this reason, for example, the column base attached to the frame at the height of the second elbow-shaped portion can exhibit a shape that complements the saddle device of the immobilization means. In this position, called the rest position, the arrangement of the assembly formed by the plate 122 and the frame is such that the first hinge part and the third support part of the intermediate frame 116 are oriented generally horizontally and the second transmission part is generally perpendicular. It is advantageous to be directed. A pulley that serves as a guide by complementarity with a groove provided in the plate 122 can be attached to the intermediate frame 116 to ensure that the frame is hooked in the lock to return to the rest position. . Advantageously, this pulley and groove set is provided at the end remote from the common node of the plate 122 and the frame.

  Reliable hooking of the frame against the plate 122 is necessary so that the opening of the trunk door 112 for handling loads is performed via an articulated connection based on a generally horizontal and rigid structure. This means that the set formed by the plates and the frame hung in the lock is supplied ready to be assembled without any variation between each assembly in the vehicle, so that when assembling the vehicle It is also advantageous for the manufacturer. The repeatability exhibited by such devices provides a gain in assembly time and quality that is advantageous to the manufacturer.

  When the trunk is opened by the rotation of the trunk door 112 around the second rotational axis in the lateral direction in the part of the trunk door 112 located at the rear of the vehicle, i.e. to enable the retraction of the roof 110 When the trunk door 112 is opened, the intermediate frame 116 is removed from the hook of the plate lock. The first pneumatic device 120 is attached to the plate 122, preferably at the bottom of the plate 122, and the free end of the piston is connected to the intermediate frame 116 as previously described. The piston of the first pneumatic device 120, which was compressed when the intermediate frame 116 was in the rest position, loosens as soon as the lock of the plate 122 no longer holds the column base of the intermediate frame 116. At this time, the stroke of this piston and its subsequent action due to fluid pressure cause rotation of the intermediate frame 116 about a rotation axis which is orthogonal to the plate 122 and thus parallel to the second rotation axis in the lateral direction. In this configuration, the second pneumatic device located between the third support portion of the frame and the support plate connected to the trunk door 112 remains compressed. The rod of the joint device located between the third support part of the intermediate frame 116 and the support plate connected to the trunk door 112 in this case remains stationary and does not articulate. The apparatus transmits the rotational movement of the intermediate frame 116 to the trunk door 112, which performs a rotational movement about the lateral axis inherent in the trunk door 112 different from the intermediate frame 116.

  This rotational movement preferably takes place about a transverse axis through the lock of the trunk door 112. This lock thus has a unique structure for taking into account the opening of the trunk, which takes place around a second lateral axis of rotation through the lock and does not exert any force on the lock, This corresponds to the case of having a conventional lock and trunk door 112 that can be moved with a hook. The lock is advantageously formed of two parts: a fixed frame connected to the structure of the vehicle body 100 of the vehicle and a hinge called a “gooseneck” that moves into the sliding groove of the frame. based on. The curved shape of the sliding groove and the corresponding shape of the hinge 118 correspond to the rotational motion about the rotational axis around which the trunk door 112 is identified as the second rotational axis of rotation. Cause movement of the hinge 118. The top of the “gooseneck” hinge 118 supports a lock seat and tongue that will correspond to the area provided in the lower portion 124 of the trunk door 112. Due to the bent connection between the frame and the hinge 118, the two parts of the lock, which are simultaneously supported by the vehicle body 100 and the trunk door 112, can be tilted in concert. The motion of the “gooseneck” hinge 118 corresponds to the motion of the lower portion of the trunk door 112. Such a combination of movements allows rotational movement of the trunk door 112 without exerting a force on the lock that contacts the trunk door 112.

  Accordingly, the opening of the trunk door 112 to retract the roof 110 is based in particular on a locking device having two independent lateral devices and a “gooseneck” hinge 118. In each lateral device, the intermediate frame 116 is formed from a single piece, which results in saving of parts and thus weight and money and good stability of each lateral device. The synchronization of the movements of the two lateral devices is realized by a delivery control corresponding to the pressure in the first pneumatic device. Such synchronization allows the mechanical protrusion connecting the two lateral devices to be opened. It should be noted that the trunk door 112 may have a predetermined flexibility that advantageously accommodates independent lateral device movement.

The assembly of the mechanism of the roof 110 and the trunk door 112 to the vehicle is performed as follows. All of the vehicle body structure, ie, the vehicle body 100 except for the door and the roof 110, arrives at the assembly line. A first set, formed in particular by a plate 122 and an intermediate frame 116 clipped to the plate 122, is attached to the lateral lateral sides inside the trunk. The set also includes a second pneumatic device, a gliding device consisting of a rod, and a support plate for connection to the trunk door 112. This set is connected to the support plate at the height of the plate 122 and clipped frame, folded slide device, jack body, and is also clipped to the support plate at the height of its piston. Together with the second pneumatic device, it is delivered to the assembly line. This end of the piston is attached to the third support of the intermediate frame 116 at the end of assembly. The end of the piston is initially clipped to a support plate for ease of operation by the operator, and then clipped and positioned on the frame as soon as the side door is installed. . It should be noted that the fact that the set of plate 122 and frame is clipped and arrives at the assembly line allows the set to be installed without variation between each assembly. The support board is then connected to the trunk door 112 when it arrives on the assembly line. At that time, the mechanism of the trunk door 112 is generally mounted. Only the first pneumatic device 120 is missing, and this first pneumatic device 120 needs to be mounted between the first hinge portion of the intermediate frame 116 and the plate 122. The first pneumatic device 120 is delivered to the assembly line together with the roof 110. In fact, the roof 110 is delivered to the assembly line with at least one hydraulic distribution box, left and right first pneumatic devices 120, a transverse plate, a closing shutter, and a mechanism associated with the transverse plate and the shutter. The fact that the hydraulic set is delivered together allows the operator to perform an easy assembly of the hydraulic cable. Once the roof 110 is in place, the operator installs the hydraulic distribution box in the trunk so that the hydraulic control necessary to move the roof 110 and trunk mechanism is transferred from the controller to the pneumatic device. It is only necessary to attach the connector to the control device. The operator also attaches the first pneumatic device 120 to the frame by attaching the jack body to the plate 122, preferably at the bottom of the plate 122, and the free end of the piston to the first hinge portion of the frame. It is necessary to attach between the plates 122. The operator also needs to connect the trunk mechanism and the handed-off horizontal plate mechanism to the roof 110 via a cable of the brake cable type of the bicycle. The synchronized operation of opening the roof 110 and the trunk door 112 is particularly ensured by this connection.
