Description

  The present invention relates to a trunk lid opening / closing mechanism.

  A trunk lid for opening and closing an opening of a cargo compartment in a vehicle is supported by an opening and closing mechanism provided between the opening of the cargo compartment. As such an opening / closing mechanism, for example, one disclosed in Patent Document 1 is employed so that the members constituting the opening / closing mechanism do not protrude toward the cargo compartment when the trunk lid is closed. The opening / closing mechanism of Patent Literature 1 includes a hinge base fixed to the trunk lid, and a first arm and a second arm for connecting the hinge base to the opening of the cargo compartment. The first arm and the second arm are provided at a distance from each other.

  The base end portion of the first arm is rotatably supported about the first base end pin with respect to the opening of the cargo compartment, while the tip end portion of the first arm is centered on the first tip pin with respect to the hinge base. It is connected as rotatable. The base end portion of the second arm is supported so as to be rotatable about the second base end pin parallel to the first base end pin with respect to the opening of the cargo compartment, while the tip end portion of the second arm is The hinge base is connected to be rotatable about a second tip pin parallel to the first tip pin.

  When the trunk lid is in the fully closed position, the first arm and the second arm are in a state of being tilted with respect to the opening of the cargo compartment, and gradually rise with respect to the opening of the cargo compartment as the trunk lid is opened. It becomes like this. In this way, the first arm and the second arm gradually rise from the state where the first arm and the second arm are tilted with respect to the opening of the luggage compartment, so that the trunk lid is moved from the fully closed position along the opening / closing track defined by the first arm and the second arm. Displacement toward the fully open position.

  By the way, when the trunk lid is displaced from the fully closed position toward the fully opened position, the size of the space between the opposing edge portions of the tip portion of the first arm and the tip portion of the second arm is determined by the trunk lid. It gradually increases in the first half of the displacement and gradually decreases in the second half of the displacement after reaching the maximum value. For this reason, when the trunk lid is displaced to the open side in the vicinity of the fully open position, the opposing edge portions of the tip portion of the first arm and the tip portion of the second arm approach each other, and the space between the two gradually increases. Becomes smaller. At this time, since the opposing edge portions of the tip portion of the first arm and the tip portion of the second arm are approaching each other, there is a possibility that an object may be caught by mistake between the edge portions.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a trunk lid opening / closing mechanism capable of suppressing an object from being accidentally sandwiched between the opposing edge portions of the first arm tip and the second arm tip when the trunk lid is opened. There is to do.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
A trunk lid opening / closing mechanism that solves the above problems is a hinge base that is fixed to a trunk lid for opening and closing an opening of a cargo compartment in a vehicle, and for connecting the hinge base to the opening of the cargo compartment. And a first arm and a second arm provided at a distance between each other. The base end portion of the first arm is rotatably supported around the first base end pin with respect to the opening of the cargo compartment, while the tip end portion of the first arm is a first tip pin with respect to the hinge base. Is connected to be rotatable around the center. The base end portion of the second arm is supported rotatably about the second base end pin parallel to the first base end pin with respect to the opening of the cargo compartment, while the tip end portion of the second arm Is connected to the hinge base so as to be rotatable around a second tip pin parallel to the first tip pin. Further, the trunk lid opening / closing mechanism includes a shielding member positioned between the edge portions when the trunk lid is opened and the opposing edge portions of the first arm tip portion and the second arm tip portion approach each other. .

  According to the above configuration, as the trunk lid is displaced toward the opening side, the opposing edge portions of the first arm tip portion and the second arm tip portion approach each other, and the space between the two gradually decreases. Even if it becomes, it can suppress that an object enters into the space by the shielding member located between the edge portions. Accordingly, when the trunk lid is opened, it is possible to prevent an object from being accidentally sandwiched between the opposing edge portions of the first arm tip portion and the second arm tip portion.

  If the second arm is provided with a full-open stopper that contacts the hinge base when the trunk lid is fully opened, the full-open stopper and the shielding member may be integrally formed. It is done.

According to this configuration, the fully open stopper and the shielding member can be assembled to the trunk lid opening / closing mechanism at a time.
Further, it is conceivable that the shielding member has a thinned portion.

  According to this configuration, the rigidity of the shielding member can be reduced by the thinned portion. For this reason, even if the edge part which the front-end | tip part of a 1st arm and the front-end | tip part of a 2nd arm approach approaches, even if an object enters into the space between both, the edge parts which the thing approaches It is suppressed by the deformation of the shielding member.

  ADVANTAGE OF THE INVENTION According to this invention, when opening a trunk lid, it can suppress that an object is pinched accidentally between the edge parts which the front-end | tip part of a 1st arm and the front-end | tip part of a 2nd arm oppose.

Sectional drawing which shows the state which looked at the 1st arm of the opening-and-closing mechanism of FIG. 3, the 2nd arm, and the shielding member from the arrow AA direction.

Hereinafter, an embodiment of a trunk lid opening / closing mechanism will be described with reference to FIGS.
As shown in FIG. 1, a luggage compartment 2 located at the rear of the vehicle 1 is provided with a trunk lid 3 for opening and closing an opening 2 a of the luggage compartment 2. The trunk lid 3 is supported by an opening / closing mechanism 4 provided between the opening 2 a of the cargo compartment 2. As the opening / closing mechanism 4, a structure is employed in which members constituting the opening / closing mechanism 4 do not protrude toward the cargo compartment 2 when the trunk lid 3 is closed.

  The opening / closing mechanism 4 includes a hinge base 5 fixed to the trunk lid 3, and a first arm 6 and a second arm 7 for connecting the hinge base 5 to the opening 2 a of the luggage compartment 2. The hinge base 5 includes a plate-like joint portion 13 joined to the back surface of the trunk lid 3 (the lower surface in FIG. 1), and a support plate 14 protruding from the joint portion 13 in a direction away from the trunk lid 3. ing.

  Further, the first arm 6 and the second arm 7 are provided at a predetermined distance in the front-rear direction of the vehicle 1 (left-right direction in FIG. 1), and the second arm 7 is more vehicle 1 than the first arm 6. Is located on the front side (left side in FIG. 1). The second arm 7 is bent so as to swell in a direction away from the first arm 6. As a result, the distance from the first arm 6 at the center of the second arm 7 in the longitudinal direction is maximized, while the distance from the center of the second arm 7 toward the end increases. The distance between is shorter.

  The opening / closing mechanism 4 also includes a plate-like bracket 8 for connecting the first arm 6 and the second arm 7 to the opening 2 a of the luggage compartment 2. The first arm 6 is located on one side in the thickness direction of the support plate 14 (the back side in the drawing in FIG. 1) and on one side in the thickness direction of the bracket 8 (the back side in the drawing in FIG. 1). The second arm 7 is located on the other side in the thickness direction of the support plate 14 (the front side in FIG. 1) and on the other side in the thickness direction of the bracket 8 (the front side in FIG. 1). Yes.

  The base end portion 6 a of the first arm 6 is connected to the bracket 8 in a state of being rotatable about the first base end pin 9, while the tip end portion 6 b of the first arm 6 is connected to the support plate 14 of the hinge base 5. On the other hand, the first base pin 9 parallel to the first base end pin 9 is connected so as to be rotatable. Further, the base end portion 7a of the second arm 7 is connected to the bracket 8 so as to be rotatable around a second base end pin 11 parallel to the first base end pin 9, while the second arm 7 The distal end portion 7 b is connected to the support plate 14 so as to be rotatable about a second distal end pin 12 parallel to the first distal end pin 10.

  The bracket 8 to which the base end portion 6 a of the first arm 6 and the base end portion 7 a of the second arm 7 are connected is fixed to the opening 2 a of the luggage compartment 2. As a result, the base end portion 6a of the first arm 6 is supported rotatably about the first base end pin 9 with respect to the opening portion 2a of the cargo chamber 2, and the base end portion 7a of the second arm 7 is loaded. The opening 2 a of the chamber 2 is supported so as to be rotatable about the second base end pin 11.

  When the trunk lid 3 is in the fully closed position as shown in FIG. 1, the first arm 6 and the second arm 7 are in a state of being tilted with respect to the opening 2a of the luggage compartment 2, and as the trunk lid 3 is opened. It gradually rises with respect to the opening 2a of the cargo compartment 2. As described above, the first arm 6 and the second arm 7 gradually rise from the state where the first arm 6 and the second arm 7 are tilted with respect to the opening 2 a of the cargo compartment 2, so that the trunk is moved along the opening / closing track determined by the first arm 6 and the second arm 7. The lid 3 is displaced from the fully closed position (FIG. 1) to the fully open position (FIG. 4) as shown in FIG. 1 → FIG. 2 → FIG. 3 → FIG.

  As can be seen from FIGS. 1 to 4, when the trunk lid 3 is displaced from the fully closed position toward the fully open position, the distal end portion 6 b of the first arm 6 and the distal end portion 7 b of the second arm 7 face each other. The size of the space between the edge portions 6c and 7c changes as follows. That is, the size of the space gradually increases in the first half of the displacement (FIG. 1 → FIG. 2) of the trunk lid 3 and reaches the maximum value (FIG. 2). 3 → Figure 4) gradually decreases. For this reason, when the trunk lid 3 is displaced to the open side in the vicinity of the fully open position, the opposing edge portions 6c and 7c of the distal end portion 6b of the first arm 6 and the distal end portion 7b of the second arm 7 approach each other. Therefore, the space between the two becomes gradually smaller.

  The second arm 7 is provided with a fully open stopper 15 that abuts against the joint portion 13 of the hinge base 5 when the trunk lid 3 is fully opened (FIG. 4). The fully open stopper 15 includes a mounting portion 16 that is mounted on the distal end portion 7b of the second arm 7 and a contact portion 18 that is formed on a portion of the mounting portion 16 opposite to the first arm 6 side. ing. The fully open stopper 15 is attached to the second arm 7 by the mounting portion 16. Further, when the trunk lid 3 is fully opened, the contact portion 18 of the fully open stopper 15 contacts the joint portion 13 of the hinge base 5 as described above, so that the trunk lid 3 is not further displaced to the open side with respect to the fully opened position. To be done.

  Further, the opening / closing mechanism 4 is configured such that when the trunk lid 3 is opened and the edge portions 6c, 7c facing each other between the distal end portion 6b of the first arm 6 and the distal end portion 7b of the second arm 7 approach each other (FIG. 3). A shielding member 17 is provided between the edge portions 6c and 7c. The shielding member 17 is located at a portion on the first arm 6 side of the mounting portion 16 of the full opening stopper 15 and is formed integrally with the full opening stopper 15. Further, the shielding member 17 has a thinned portion 19. The thinned portion 19 is provided in the shielding member 17 by forming a hole that penetrates the shielding member 17 in a direction orthogonal to the paper surface of FIGS.

Next, the effect of the opening / closing mechanism 4 of the trunk lid 3 will be described.
(1) As shown in FIG. 5, the edge portions 6c and 7c facing each other between the distal end portion 6b of the first arm 6 and the distal end portion 7b of the second arm 7 approach each other with the displacement of the trunk lid 3 toward the opening side. When the space between the two becomes gradually smaller, the shielding member 17 is positioned between the edge portions 6c and 7c. Therefore, when the trunk lid 3 is opened, the shielding member 17 indicates that an object enters the space between the edge portions 6c, 7c facing each other between the tip portion 6b of the first arm 6 and the tip portion 7b of the second arm 7. Therefore, it is possible to prevent the object from being sandwiched between the edge portions 6c and 7c.

  (2) Since the fully open stopper 15 attached to the tip 7b of the second arm 7 and the shielding member 17 are integrally formed, the fully open stopper 15 is attached to the tip 7b of the second arm 7. Thus, the shielding member 17 can be assembled to the opening / closing mechanism 4, and the fully open stopper 15 and the shielding member 17 can be assembled to the opening / closing mechanism 4 at a time.

  (3) Since the second arm 7 is bent so as to swell in the direction away from the first arm 6, the edge portions 6c, 7c facing each other between the tip portion 6b of the first arm 6 and the tip portion 7b of the second arm 7 are opposed to each other. The space between can be made large. For this reason, along with the displacement of the trunk lid 3 toward the opening side, the edge portions 6c, 7c facing each other between the tip portion 6b of the first arm 6 and the tip portion 7b of the second arm 7 approach each other, and between them When the space is gradually reduced, it becomes difficult for objects to be caught between the edge portions 6c and 7c by taking the space larger.

  (4) Since the shielding member 17 has the lightening part 19, the rigidity of the shielding member 17 can be reduced by the lightening part 19. For this reason, when the edge portions 6c and 7c facing each other between the tip portion 6b of the first arm 6 and the tip portion 7b of the second arm 7 approach each other, even if an object enters the space between the two, It can suppress by the deformation | transformation of the said shielding member 17 that it is pinched between the edge parts 6c and 7c which an object approaches.

In addition, the said embodiment can also be changed as follows, for example.
-About the lightening part 19 of the shielding member 17, you may make it provide in the shielding member 17 by forming the hollow dented in the direction orthogonal to the paper surface of FIGS.

The shielding member 17 may be a separate body from the fully open stopper 15.
When the shielding member 17 is separated from the fully open stopper 15, the shielding member 17 may be attached to the distal end portion 7 b of the second arm 7 or attached to the distal end portion 6 b of the first arm 6. You may make it do.
