Description

  The present invention relates to a laterally open lid that is attached to an opening provided on an outer peripheral surface of a vehicle body and rotates about a rotation axis along a vertical direction.

  Patent Document 1 discloses a door opening and holding device attached between a vehicle body and a front panel in order to hold the front panel connected to a vehicle body serving as a main body of a truck or the like with a hinge. This door opening and holding device has a pair of arms pivotably attached to each other in the middle. At least one of the arms is formed with a restraining portion that holds the angle at which the intermediate pivot point from the fulcrum serving as both ends of the link exceeds 180 °. The arms are biased so that they are restrained by a spring beyond 180 °.

  In order to cover the opening provided facing the outer periphery of the vehicle body, a lid is provided in which one side of the outer periphery is connected to the vehicle body by a lid with a hinge. The lid includes a vertical opening lid in which the rotation center axis of the hinge is arranged along the horizontal direction, and a horizontal opening lid in which the rotation center axis of the hinge is arranged in the vertical direction.

In either case of the vertically open lid or the horizontally open lid, it is easily assumed that a holding device as in Patent Document 1 is provided between the lid and the vehicle body in consideration of workability and safety in the opened state. Is done. The lids of these lids are fixed by a lock mechanism or the like so as not to open carelessly while the vehicle is running. Moreover, there exists a thing provided so that a lock mechanism may be cancelled | released by the remote operation by a wire cable from the position away from the lid so that it may not be opened by the third party during parking.
JP-A-9-125789

  However, when the locking mechanism is operated at a position away from the lid, the lid opens sideways when the locking mechanism is released depending on the inclination state of the place where the vehicle is stopped. There is a possibility of hitting something in the vicinity.

  In this case, even if a door having the same structure as the door opening and holding device described in Patent Document 1 is provided between the lateral opening lid and the vehicle body, the lid of the lateral opening lid is still opened.

  Therefore, according to the present invention, in a laterally opened lid in which the lock mechanism is remotely operated, when the lock mechanism is released, the lid temporarily stops at the protruding position where the lid protrudes from the vehicle body, and the lid is fixed even in the fully opened position. The purpose is to provide a side-opening lid.

  The laterally open lid of the present invention includes a lid, a hinge, a lock mechanism, an operation unit, and a link mechanism. The lid closes an opening provided facing the outside of the vehicle body. The hinge pivots the lid on the vehicle body. The lock mechanism fixes the lid in a closed position where the opening is closed. The operation unit is operated at a position away from the opening to release the lock mechanism. The link mechanism limits the opening angle of the lid.

  The link mechanism includes a first arm, a second arm, a primary locking mechanism, and a secondary locking mechanism. One end of the first arm is pivotally attached to the inner edge of the opening away from the hinge. One end of the second arm is pivotally attached to the edge of the lid corresponding to the inner edge of the opening to which the first arm is pivotally attached, and the other end is connected to the other end of the first arm. The primary locking mechanism is provided between the first arm and the second arm, and temporarily restricts the movement in the direction in which the lid is opened at the protruding position that protrudes from the vehicle body near the opening in the rotation range of the lid. To do. When the lid is opened, the secondary locking mechanism is configured such that the rotation center of the connecting portion between the other end of the first arm and the other end of the second arm is provided at one end of the first arm. After the line segment connecting the moving center and the rotation center provided at one end of the second arm exceeds the other side from one side, the first arm and the second arm centering on the connecting portion Limit further rotation.

  In this case, a preferred form of the primary locking mechanism is provided in the middle of each of the first arm and the second arm, interferes with each other in the rotation direction, and is in the direction crossing the rotation direction. At least one of the arm and the second arm is configured by an engaging portion that can avoid mutual interference by elastically deforming.

  With this configuration, when the lid is to be opened, the primary locking mechanism interferes in the direction in which the first arm and the second arm rotate. Thereby, the rotation angle of both arms is restricted, and the movement in the direction in which the lid is opened stops once. Further, when the cover is rotated in the opening direction, at least one of the first arm and the second arm is elastically deformed in a direction crossing the rotation direction of these arms, and the interference state of both arms is released. The lid can be further opened.

  Another preferable form of the primary locking mechanism includes a locking projection and a locking recess. The locking projection is provided in the middle of the second arm, and gently protrudes toward the first arm in a direction crossing the rotational direction of the second arm. The locking recess is provided in the first arm corresponding to the locking protrusion, and is formed long along the rotation direction of the second arm with respect to the first arm. The locking recess is loosely fitted with the locking protrusion within a range in which the lid rotates from the closed position to the protruding position.

  By having this configuration, the locking projection and the locking recess interfere with each other in the rotational direction of the first arm and the second arm, and when the lid is opened, the lid slightly protrudes from the vehicle body. Stop once in position. Then, the operator can further open the cover by placing his hand.

  Still another preferred form of the primary locking mechanism includes a locking piece and a guide portion. The locking piece is provided in the middle of the first arm, extends toward the outside of the vehicle body in a state where the lid is in the closed position, and extends in a direction crossing the rotational direction of the first arm. A streak-like bent portion that gently protrudes toward the side is formed. The guide portion is provided on the second arm corresponding to the locking piece, and the locking piece gets over the rotation direction of the second arm. The bent portion rides on the guide portion when the lid is rotated from the protruding position toward the outside of the vehicle body, and is in sliding contact with the guide portion in a line crossing the rotation direction of the second arm with respect to the first arm. .

  At the position where the lid protrudes outside the vehicle, the locking piece and the guide portion come in linear contact with each other, reducing the local load and reducing the mutual wear amount between the first arm and the second arm. Is done.

  In a preferred form of the secondary locking mechanism, the rotation center of the connecting portion is a line segment connecting the rotation center provided at one end of the first arm and the rotation center provided at one end of the second arm. The first arm and the second arm abut on each other in the rotational direction about the connecting portion, so that the first arm and the second arm Provided to limit rotation.

  With this configuration, the secondary locking mechanism abuts on each other by the configuration formed on the first arm and the second arm, and restricts the rotation of the first arm and the second arm. . Therefore, the structure of the secondary locking mechanism is simple and the cost is low.

  It is also preferable that the pivot center axis of the hinge is inclined toward the direction in which the upper end is away from the vehicle body. As a result, when the lock mechanism is released by remote operation, the lid rotates in its opening direction toward the outside of the vehicle body under its own weight.

  According to the lateral opening lid according to the present invention, since the primary locking mechanism is provided, even when the lock mechanism is released by remote operation, the lid is temporarily stopped with the lid protruding from the vehicle body. Therefore, this side-opening lid can prevent the lid from opening freely due to the influence of the inclination of the vehicle body or the wind even when the lock is released. And it can prevent that a lid | cover collides with the thing placed in the periphery and is mutually damaged.

  Moreover, since this laterally-open lid includes a secondary locking mechanism, the lid is fixed even when the lid is fully opened. Therefore, this side-opening lid can be operated with peace of mind without being bothered by the movement of the lid for the operator working at the opening and its periphery.

  Furthermore, since the lock mechanism is released by remote operation, it is possible to prevent the lid from being opened due to a tampering from the outside.

  The laterally open lid 10 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 9. The present embodiment shows a laterally open lid 10 applied to the battery storage unit 2 of the large bus 1. As shown in FIG. 1, the laterally open lid 10 is disposed under the right driver's seat at the front of the vehicle body 3. The lid 11 is pivotally supported by a hinge 12 provided on the front side of the vehicle body 3 as shown in FIG. 12, and is provided so as to open from the rear side as shown in FIG. For convenience of explanation, the front and rear, left and right, and the vertical direction in the height direction of the large bus 1 are defined based on the traveling direction of the large bus 1.

  As shown in FIG. 2, the laterally open lid 10 includes a lid 11, a hinge 12, a lock mechanism 13, an operation unit 14, and a link mechanism 15. The lid 11 closes the opening 4 of the battery storage unit 2 provided facing the outside of the vehicle body 3. The lid 11 is provided so that the outer surface is flush with the surroundings in a completely closed state. A pair of hinges 12 are arranged vertically on the front edge of the opening 4 and pivotally support the lid 11 on the vehicle body 3. As shown in FIG. 3, the rotation center shaft 12 a of the hinge 12 is provided such that the upper end side is inclined outward in the vehicle width direction with respect to the vertical direction of the vehicle body 3.

  The lock mechanism 13 includes a striker 13a and a latch 13b, and is provided at a position away from the front edge of the opening 4 where the hinge 12 is provided. A striker 13a is attached to the upper part and the lower part from the rear of the lid 11, and a latch 13b incorporating a hook is attached to the upper and lower edges of the rear part of the opening 4 correspondingly. Each lock mechanism 13 fixes the lid 11 at a closed position P1 that closes the opening 4 as shown in FIG. The operation unit 14 includes an opener handle 14a and a wire cable 14b.

  The opener handle 14 a is disposed inside the vehicle body 3 at a position away from the opening 4. A hatch 14 c is provided on the outer panel 3 a of the vehicle body 3 so that the opener handle 14 a can be accessed from outside the vehicle body 3. The wire cable 14b links the hooks of the lock mechanisms 13 and the opener handle 14a. The lock mechanism 13 is released by operating the opener handle 14a. By providing this configuration, the lid 11 is prevented from being opened from the outside due to mischief.

  As shown in FIGS. 2 and 3, the link mechanism 15 is connected between the upper edge of the opening 4 and the upper part of the lid, and limits the opening angle of the lid 11. The link mechanism 15 bends and moves along a plane perpendicular to the rotation center axis 12 a of the hinge 12. As shown in FIG. 4, the link mechanism 15 includes a first arm 21, a second arm 22, a primary locking mechanism 23, and a secondary locking mechanism 24.

  As shown in FIG. 2, one end 21 a of the first arm 21 is pivotally attached to a vehicle body side bracket 25 fixed to the upper edge of the opening 4 away from the hinge 12 with a bolt. One end 22a of the second arm 22 is pivotally attached to a lid side bracket 26 that is fixed to the upper portion of the lid 11 corresponding to the upper edge of the opening 4 to which the first arm 21 is pivotally attached. As shown in FIG. 4, the other end 21b of the first arm 21 and the other end 22b of the second arm 22 are connected to each other so as to be rotatable. As shown in FIG. 3, the first arm 21 and the second arm 22 move along a plane perpendicular to the rotation center axis 12 a of the hinge 12. The bolt holes provided in the vehicle body side bracket 25 and the lid side bracket 26 are long holes for facilitating fixing of the respective brackets.

  As shown in FIGS. 8 and 9, the lid side bracket 26 is provided at a position farther from the vehicle body side bracket 25 than the hinge 12. The connecting portion 27 between the first arm 21 and the second arm 22 is located farther than the vehicle body side bracket 25 and the lid side bracket 26 with respect to the hinge 12 in a state where the lid 11 is closed. In FIG. 4, bolts for fixing the vehicle body side bracket 25 and the lid side bracket 26 are omitted.

  The primary locking mechanism 23 is provided between the first arm 21 and the second arm 22. The primary locking mechanism 23 includes a locking projection 23a and a locking recess 23b. In the present embodiment, the locking projection 23a is provided in the middle of the second arm 22 as shown in FIG. 4, and in the direction crossing the rotational direction of the second arm 22, FIG. 6 and FIG. 7 gently protrudes toward the first arm 21 side.

  The locking recess 23b is provided on the first arm 21 corresponding to the locking projection 23a as shown in FIG. 4, and is loosely fitted with the locking projection 23a as shown in FIG. As shown in FIGS. 5 and 8, the locking recess 23 b is an arc-shaped long hole formed long along the rotation direction of the second arm 22 with respect to the first arm 21. The locking projection 23a and the locking recess 23b interfere with each other in the rotational direction of the first arm 21 and the second arm 22, and the first arm 21 and the second arm as shown in FIG. The relative rotation angle α with respect to 22 is regulated.

  The amount of rotation of the first arm 21 and the second arm 22 at this time is proportional to the distance that the locking projection 23a can move in the locking recess 23b of the arcuate long hole, as shown in FIG. In addition, the amount corresponds to the position from the closed position P1 at which the lid closes the opening 4 to the protruding position P2 at which the lid 11 protrudes from the vehicle body 3 near the opening 4. Accordingly, the primary locking mechanism 23 temporarily restricts the movement of the lid 11 in the opening direction at the protruding position P2 in the rotation range of the lid 11.

  Further, when the operator puts his hand on the lid 11 and opens it, the first arm 21 and the second arm 22 are rotated in the opening direction, and at least one of the first arm 21 and the second arm 22 is opened. Due to elastic deformation, the locking projection 23a is disengaged from the locking recess 23b. As a result, the link mechanism 15 can be opened as shown in FIG. In the present embodiment, the locking recess 23b only needs to limit the amount of movement of the locking projection 23a, that is, the amount of rotation of the first arm 21 and the second arm 22, and thus is long. Shapes other than holes may be used.

  The secondary locking mechanism 24 includes the first arm 21 and the second arm 22 so that the connecting portion 27 between the first arm 21 and the second arm 22 does not rotate and the lid 11 does not close. The rotation angle is limited. That is, as shown in FIG. 9, the secondary locking mechanism 24 is provided at the one end 21 a of the first arm 21 after the lid 11 is opened beyond the rotation restriction range of the primary locking mechanism 23. The rotation center T of the connecting portion 27 extends from one side to the other side of the line segment S connecting the one rotation center S1 and the second rotation center S2 provided at one end 22a of the second arm 22. Later, further rotation of the first arm 21 and the second arm 22 around the connecting portion 27 is restricted.

  More specifically, the secondary locking mechanism 24 is on the side where the line segment S connecting the first rotation center S1 and the second rotation center S2 passes with respect to the rotation center T of the connecting portion 27. The first arm 21 and the second arm 22 abut on each other in the rotation direction about the connecting portion 27, thereby restricting the rotation of the first arm 21 and the second arm 22. . In the present embodiment, when the lid 11 is opened as shown in FIG. 9, the direction of blocking the turning direction as shown in FIG. 4 on the side far from the hinge 12 with respect to the turning center T of the connecting portion 27. The edge 21c of the first arm 21 bent in the direction of the first arm 21 and the edge 22c of the second arm 22 blocked by the rotation direction are brought into contact with each other.

  As described above, the rotation center T of the connecting portion 27 exceeds the line segment S connecting the first rotation center S1 and the second rotation center S2 from the closed position P1 side to the opposite side. Even if the lid 11 is pushed back toward the vehicle body 3, the first arm 21 and the second arm 22 are restrained by the secondary locking mechanism 24, so that the lid 11 is not inadvertently closed.

  The laterally open lid 10 configured as described above operates as follows. When the lid 11 is in the closed position P1 as shown in FIG. 9A, the first arm 21 and the second arm 22 of the link mechanism 15 are folded back by the connecting portion 27 as shown in FIG. It is the state where it overlapped. When the lock mechanism 13 is released by the operation unit 14, the packing 5 is provided between the lid 11 and the opening 4, and the upper end of the rotation center shaft 12 a of the hinge 12 is inclined toward the outside of the vehicle body 3. Therefore, the lid 11 moves outward of the vehicle body 3 by its own weight. At this time, the lid 11 is opened only by the primary locking mechanism 23 to the protruding position P2 near the opening 4 as shown in FIG.

  When the lid 11 is manually pulled open, the rotation restriction by the primary locking mechanism 23 is released and further opened. The lid 11 is completely opened to the open position P3 shown in FIG. 9C, and the connecting portion 27 is connected to the first rotation center S1 and the second rotation center S2 so that the secondary locking mechanism 24 functions. The line segment S connecting is exceeded. In this state, even if the lid 11 acts in the closing direction, the edge 21c of the first arm 21 and the edge 22c of the second arm abut against each other, and the first arm 21 and the second arm 22 Further rotation around the connecting portion 27 is prevented. Therefore, the lid 11 is prevented from being inadvertently closed.

  Further, when the lid 11 is closed, the lid 11 may be pushed back while pulling back the connecting portion 27 in a direction away from the hinge 12. A slope 23c is formed on the first arm 21 so that the locking projection 23a can easily return to the locking recess 23b. In order to suppress wear of the locking projection 23a, it is also preferable to provide R at the corner of the locking recess 23b.

  The link mechanism 15a in the laterally open lid according to the second embodiment of the present invention will be described with reference to FIGS. Since the configuration other than the link mechanism 15a is the same as that of the laterally open lid 10 of the first embodiment, description thereof will be omitted here with reference to FIGS. 1 to 9 and the description thereof.

  The link mechanism 15a shown in FIG. 10 differs in the structure of the primary locking mechanism 23. FIG. The primary locking mechanism 23 includes a locking piece 23d and a guide portion 23e. The locking piece 23d is provided in the middle of the first arm 21 so as to extend toward the outside of the vehicle body 3 with the lid 11 in the closed position P1. Further, as shown in FIG. 11, the locking piece 23d is formed with a stripe-like bent portion 23f that gently protrudes toward the second arm 22 in a direction crossing the rotational direction of the first arm 21. ing. The guide portion 23e is provided on the second arm 22 corresponding to the locking piece 23d, and gets over the locking piece 23d in the rotating direction of the second arm 22.

  As shown in FIG. 12, the bent portion 23f is provided in parallel with the edge of the guide portion 23e so as to come into linear contact with the guide portion 23e when the lid 11 is in the protruding position P2. Then, when the lid 11 further rotates from the protruding position P2 toward the outside of the vehicle body 3, the bent portion 23f rides on the guide portion 23e and crosses the second arm 22 while being in sliding contact with the guide portion 23e.

  In the link mechanism 15a configured as described above, the locking piece 23d and the guide portion 23e are linearly contacted at the protruding position P2, so that the local load is reduced and the amount of wear of each other can be reduced. .

  The primary locking mechanism 23 of the link mechanism in the laterally open lid according to the third embodiment of the present invention will be described with reference to FIG. Since the other configuration as the laterally open lid is the same as that of the laterally open lid 10 of the first embodiment, description thereof is omitted here with reference to FIGS. 1 to 9 and the description thereof.

By doing so, the size of the locking projection 23a can be easily adjusted, and even when the locking projection 23a is worn over time, it can be easily repaired by replacing the rivet. .

  The primary locking mechanism 23 of the link mechanism in the laterally open lid according to the fourth embodiment of the present invention will be described with reference to FIG. Since the other configuration as the laterally open lid is the same as that of the laterally open lid 10 of the first embodiment, description thereof is omitted here with reference to FIGS. 1 to 9 and the description thereof.

  The primary locking mechanism 23 of the link mechanism shown in FIG. 14 is provided with a first convex portion 23m projecting to the second arm 22 side on the first arm 21 side, and a second projecting to the first arm 21 side. Is provided on the second arm 22 side. By doing in this way, since the apparent thickness of the second arm 22 increases, the rigidity against bending in the direction crossing the rotational direction is increased. Moreover, it is preferable that the 1st convex part 23m and the 2nd convex part 23n have a length in the radial direction from the connection part 27, and are formed. As a result, the local stress when the first convex portion 23m and the second convex portion 23n are in contact with each other is reduced, and the distance between each other is short, so that wear can be reduced.

  In each embodiment, the relationship between the first arm 21 and the second arm 22 may be reversed. That is, the first arm 21 may be pivotally attached to the lid 11 side, and the second arm 22 may be pivotally attached to the opening 4 side of the vehicle body 3. Further, the primary locking mechanism 23 and the secondary locking mechanism 24 provided between the first arm 21 and the second arm 22 are also configured with the first arm 21 side and the second arm 22 side. May be provided in reverse.

  Further, the primary locking mechanism 23 is provided in the middle of each of the first arm 21 and the second arm 22 and interferes with each other in the rotation direction, and the first arm in a direction crossing the rotation direction.
