Description

  The present invention relates to a canvas top-equipped vehicle, a canvas top unit provided on the vehicle, and a method for attaching such a canvas top unit.

  For example, as seen in Patent Document 1, a canvas top-equipped vehicle is known in which a canvas top unit including a canvas top and a rail that supports the canvas top so as to be freely opened and closed is attached to an opening formed in a roof portion of a vehicle body. It has been. When attaching such a canvas top unit to the vehicle body roof portion, a reference pin provided on the canvas top unit is engaged with a reference hole formed at the periphery of the opening of the vehicle body roof portion, thereby The attachment position may be determined.

Japanese Patent Laid-Open No. 04-056629

  In such a canvas top-equipped vehicle, when the vehicle body is twisted due to a rough road or the like, a relative displacement occurs between the vehicle body and the canvas top unit. At this time, since the relative displacement is restrained in the engagement portion of the reference pin / reference hole as described above, a high stress is generated in the vicinity thereof. Therefore, such portions require high strength, which may increase costs and weight.

  The present invention has been made in view of such circumstances, and a problem to be solved is to make it easy to ensure durability against the torsion of the vehicle body.

  A canvas top-equipped vehicle that solves the above problems is a canvas top-equipped vehicle in which a canvas top unit is attached to an opening formed in a roof portion of the vehicle body. A convex portion provided on the other side of the canvas top unit is inserted, and a gap is formed between the inner periphery of the hole and the outer periphery of the convex portion.

  In the above configuration, by attaching the reference pin engaged with the hole to the convex portion so as to be detachable, it is possible to determine the attachment position when attaching the canvas top unit to the vehicle body. Since the convex part left after the separation of the reference pin is formed so as to leave a gap between the outer periphery thereof and the inner periphery of the hole to which the reference pin is engaged, in the formation part of the convex part and the hole, The relative displacement between the vehicle body and the canvas top unit for the gap is allowed. Therefore, when the vehicle body is twisted, the stress generated in such a part is suppressed. Therefore, according to the said structure, ensuring of the durable strength with respect to the twist of a vehicle body becomes easy.

  In addition, it is desirable to make the convex part in such a canvas top mounting vehicle into a male screw. In such a case, the reference pin can be attached to the convex portion by screwing, and the reference pin can be fixed and detached from the convex portion more easily and reliably.

  Moreover, it is desirable to provide the holes and the convex portions in the canvas top-equipped vehicle at the corners of the vehicle body and the canvas top unit. In such a case, it becomes easy to secure an opening area when the canvas top is opened.

  Further, in such a canvas top-equipped vehicle, it is desirable to provide a hole or a convex portion on the roof panel of the vehicle body. When a vehicle with a canvas top is manufactured as a derivative of a vehicle without a canvas top, the roof panel of the vehicle body needs to be changed. In that respect, in the above configuration, since a structure for determining the attachment position of the canvas top unit is provided in such a roof panel, more parts can be shared.

  In the canvas top unit that solves the above-described problems, a reference pin for determining the attachment position of the canvas top unit with respect to the vehicle body is detachably attached to the canvas top unit attached to the opening formed in the roof portion of the vehicle body. ing.

  In the above configuration, the attachment position of the canvas top unit to the vehicle body can be determined by engaging the reference pin with the reference hole formed in the vehicle body. If the reference pin is removed after the attachment position is determined, the relative displacement between the vehicle body and the canvas top unit due to the engagement between the reference pin and the reference hole is eliminated, and the height when the vehicle body is twisted is increased. Generation of stress can be suppressed. Therefore, according to the said structure, ensuring of the durable strength with respect to the twist of a vehicle body becomes easy.

  In addition, it is desirable that the reference pin in such a canvas top unit is attached to the canvas top unit by screwing. In such a case, it is possible to more easily and reliably fix and remove the reference pin from the canvas top unit.

  Further, it is desirable that the reference pin in such a canvas top unit is attached to a corner portion of the canvas top unit. In such a case, it becomes easy to secure an opening area when the canvas top is opened.

  A method for attaching a canvas top unit for solving the above-described problem is a method for attaching a canvas top unit to an opening formed in a roof portion of a vehicle body, and the vehicle body with respect to a hole provided in one of the vehicle body and the canvas top unit. The position of the canvas top unit attached to the vehicle body is determined through the engagement of the reference pin removably attached to the other of the canvas top unit, and the reference pin is moved from the other of the vehicle body and the canvas top unit after the attachment position is determined. I try to leave.

  In the above attachment method, the reference pin is detached after determining the attachment position of the canvas top unit with respect to the vehicle body. Therefore, the relative displacement between the vehicle body and the canvas top unit due to the engagement between the reference pin and the reference hole is eliminated, and the generation of high stress when the vehicle body is twisted can be suppressed. Therefore, according to the above attachment method, it is easy to ensure the durability strength against torsion of the vehicle body.

  In addition, it is desirable to attach the detachable reference pin to the other of the vehicle body and the canvas top unit in such an attachment method by screwing. In such a case, it is possible to more easily and reliably fix and remove the reference pin from the canvas top unit.

  In addition, it is desirable that the reference hole and the reference pin in such an attachment method are provided at the corners of the vehicle body and the canvas top unit. In such a case, it becomes easy to secure an opening area when the canvas top is opened.

  Furthermore, in such an attachment method, it is desirable to provide a reference hole or a reference pin on the roof panel of the vehicle body. In such a case, since the structure relating to the determination of the attachment position of the canvas top unit is provided in the vehicle body part of the roof portion, more parts can be shared with the vehicle not equipped with the canvas top.

  Hereinafter, an embodiment of a canvas top-equipped vehicle, a canvas top unit, and an attachment method thereof will be described in detail with reference to FIGS. Note that the canvas top-equipped vehicle of the present embodiment is designed on the basis of a vehicle without the canvas top, and has substantially the same configuration as the vehicle that is the base except for the roof portion of the vehicle body.

  FIG. 1 shows a configuration of a roof portion of a vehicle body of a vehicle equipped with a canvas top. In the same figure and each figure described later, arrow F indicates the front of the vehicle, arrow B indicates the rear of the vehicle, arrow L indicates the vehicle left, arrow R indicates the vehicle right, arrow U indicates the vehicle upper, and arrow D. Indicates the lower part of the vehicle body.

  As shown in the figure, left and right roof side rails 10 and 11 extending in the longitudinal direction of the vehicle body are provided on both sides of the roof portion. The left and right roof side rails 10, 11 are connected to each other by a front header 12 extending in the left-right direction of the vehicle body at the front end of the roof. The left and right roof side rails 10 and 11 are connected to each other by a rear header 13 extending in the left-right direction of the vehicle body at the rear end of the vehicle body of the roof portion. The roof side rails 10, 11, the front header 12, and the rear header 13 form a skeleton of the roof portion of the vehicle body.

  Further, the roof portion of the vehicle body is provided with a front roof panel 14 covering the front end of the vehicle body and a rear roof panel 15 covering the rear end of the vehicle body as exterior members. A canvas top unit 17 is attached to an opening 16 formed between the front roof panel 14 and the rear roof panel 15. Note that, in a vehicle not equipped with a canvas top, which is the base of the vehicle equipped with a canvas top, the entire roof portion is covered with a single roof panel.

  The canvas top unit 17 is attached to the opening 16 after determining an attachment position using a reference pin. The details of the structure for determining the mounting position will be described below.

  FIG. 2 shows a planar structure of the canvas top unit 17 viewed from the passenger compartment side. As shown in the figure, the canvas top unit 17 is provided with the reference pins 18 for determining the mounting position as described above at the left and right corners A and B in front of the vehicle body.

  As shown in FIG. 3, at the left and right corners A and B of the canvas top unit 17 in front of the vehicle body, a base 19 is fixed to the surface on the passenger compartment side by welding or the like. The base 19 is integrally formed with a convex portion 20 having a male thread on the side periphery so as to protrude toward the passenger compartment. On the other hand, a female screw hole 21 is formed in the axial direction from the base end of the reference pin 18 formed in a substantially cylindrical shape with a sharp tip. The reference pin 18 is detachably attached to the base portion 19 by screwing the female screw hole 21 and the convex portion 20.

  As shown in FIG. 4, reference holes 22 formed as circular holes having substantially the same diameter as the outer diameter of the reference pin 18 are respectively formed at the peripheral edges of the opening 16 at the left and right corners of the front portion of the roof of the vehicle body. Is formed. In this canvas top-equipped vehicle, the reference hole 22 is provided in the front header 12.

Attachment of the canvas top unit 17 to the vehicle body in the canvas top-equipped vehicle configured as described above is performed as follows.
As shown in FIG. 5, when attaching the canvas top unit 17, first, the canvas top unit is inserted into the opening 16 provided in the roof portion of the vehicle body so that each reference pin 18 is inserted into the corresponding reference hole 22, respectively. 17 is attached.

  FIG. 6 shows the state of the reference pin 18 at this time. As shown in the figure, each reference pin 18 is engaged with a corresponding reference hole 22, and as a result, the attachment position of the canvas top unit 17 with respect to the vehicle body is determined. In addition, the arrow IN in the same figure and each figure mentioned later shows the insertion direction of the reference pin 18 (convex part 20) with respect to the reference hole 22, and the arrow OUT shows the removal direction of the reference pin 18 from the reference hole 22, respectively. Show.

  Subsequently, the canvas top unit 17 is fixed to the vehicle body. The canvas top unit 17 is fixed to the vehicle body by spot welding, for example. Thereafter, the reference pin 18 is detached from the base 19.

FIG. 7 shows a state in the vicinity of the reference hole 22 after the reference pin 18 is detached. As shown in the figure, only the convex portion 20 of the base portion 19 remains in the reference hole 22 at this time.
FIG. 8 shows a side sectional structure in the vicinity of the reference hole 22 at this time. As shown in the figure, the outer diameter d1 of the convex portion 20 is smaller than the inner diameter d2 of the reference hole 22.

  FIG. 9 shows a cross-sectional structure of the protrusion 20 and the reference hole 22 along the line S2-S2 of FIG. This cross section is a cross section orthogonal to the insertion direction of the convex portion 20 with respect to the reference hole 22 (here, the extending direction of the central axis L of the reference hole 22 and the convex portion 20). As described above, since the outer diameter d1 of the convex portion 20 is smaller than the inner diameter d2 of the reference hole 22, a gap is formed between the inner periphery of the reference hole 22 and the outer periphery of the convex portion 20 in this cross section. .

Next, the operation of this embodiment will be described.
If the reference pin 18 remains left after the canvas top unit 17 is attached, the relative displacement between the canvas top unit 17 and the front roof panel 14 is restricted by the engaging portion of the reference pin 18 and the reference hole 22. . On the other hand, in the present embodiment, the reference pin 18 is detached after the canvas top unit 17 is attached, and a gap is left between the outer periphery of the convex portion 20 of the base portion 19 and the inner periphery of the reference hole 22 left after that. It is formed. Therefore, relative displacement between the canvas top unit 17 and the front roof panel 14 is allowed by the gap in the engaging portion.

  FIG. 10 exaggerates the deformation of each member when the vehicle body is twisted in a state where the relative displacement is restrained by the reference pin 18. In the figure, the state before the occurrence of twisting is indicated by a one-dot chain line, and the state at the time of occurrence of twisting is indicated by a solid line. Note that FIG. 11 and FIG. 11 described later correspond to a cross section taken along line S1-S1 in FIG.

  In such a case, the relative displacement between the canvas top unit 17 and the front roof panel 14 is restricted at the engaging portion between the reference pin 18 and the reference hole 22. In such a case, the front roof panel 14 follows the displacement of the canvas top unit 17 according to the twist of the vehicle body as shown by the arrow in the figure. Therefore, according to the displacement of the canvas top unit 17, the distance between the welded portion W of the roof side rail 10 and the front roof panel 14 and the reference pin 18 is narrowed, and the front roof panel 14 and the like may be greatly deformed.

  FIG. 11 shows exaggeratedly the deformation modes of each member when the vehicle body is twisted when the reference pin 18 is detached and the relative displacement is not restricted. Also in this figure, the state before the occurrence of twisting is indicated by a one-dot chain line, and the state at the time of occurrence of twisting is indicated by a solid line. In the figure, the base 19 is not shown.

  At this time, relative displacement between the canvas top unit 17 and the front roof panel 14 as shown by an arrow in the drawing is allowed to some extent. Therefore, the front roof panel 14 hardly follows the displacement of the canvas top unit 17 according to the twist of the vehicle body, and deformation of the front roof panel 14 is suppressed.

  Incidentally, as described above, if the reference pin 18 remains, stress generated by twisting the vehicle body becomes large. Therefore, in such a case, the installation position of the reference pin 18 is a portion where the relative displacement between the vehicle body and the canvas top unit 17 due to torsion of the vehicle body is small, specifically, near the center in the vehicle longitudinal direction on both sides of the canvas top unit 17. It may be limited to the part of. However, in such a case, since the reference pin 18 is installed, the width of the outer frame of the canvas top unit 17 becomes wide, and the opening area when the canvas top is opened becomes small. In this respect, in this embodiment, since the stress generated by the twisting of the vehicle body is suppressed by the detachment of the reference pin 18, the installation location of the reference pin 18 can be freely set. Therefore, in the present embodiment, the reference pins 18 are installed at the corners of the canvas top unit 17, thereby avoiding an increase in the width of the outer frame and securing an opening area when the canvas top is opened.

In this embodiment, the reference hole 22 corresponds to “a hole formed in one of the vehicle body and the canvas top unit”.
According to this embodiment described above, the following effects can be obtained.

  (1) In this embodiment, the reference pin 18 for determining the attachment position of the canvas top unit 17 with respect to the vehicle body is detachably provided. Therefore, if the reference pin 18 is detached after determining the attachment position of the canvas top unit 17 with respect to the vehicle body, the relative displacement between the vehicle body and the canvas top unit 17 due to the engagement between the reference pin 18 and the reference hole 22 is reduced. The restraint is eliminated, and the generation of high stress when the vehicle body is twisted is suppressed. Therefore, it is possible to easily ensure the durability strength against the torsion of the vehicle body.

  (2) In the above embodiment, the reference pin 18 is attached to the canvas top unit 17 by screwing. For this reason, the reference pin 18 can be detached without being deformed or tilted, and the reference pin 18 is hardly detached by itself before the attachment is completed. Therefore, the reference pin 18 can be fixed and detached more easily and reliably.

(3) Since the reference pins 18 are provided at the corners of the canvas top unit 17, it is easy to secure an opening area when the canvas top is opened.
(4) Since the reference hole 22 is provided in the front roof panel 14 which is a dedicated part for the canvas top-equipped vehicle, more parts can be shared with the vehicle not equipped with the canvas top.

In addition, the said embodiment can also be changed and implemented as follows.
Even if the reference pins 18 and the reference holes 22 are provided at the left and right corners at the rear end of the canvas top unit 17 and the opening 16, the opening area when the canvas top is opened can be easily secured. Is possible.

  In the above embodiment, the reference pins 18 are provided at two locations, but the number thereof may be changed. In order to reliably determine the attachment position, it is desirable to provide the reference pin 18 at a plurality of locations instead of only one location.

If the sufficient opening area can be secured when the canvas top is opened, the reference pins 18 may be provided at positions other than the corners.
In the above embodiment, the reference hole 22 is provided in the roof panel. When there is not much demand for common parts with a vehicle not equipped with a canvas top, a reference hole 22 is provided in a member other than the roof panel, such as the roof side rails 10, 11, the front header 12, and the rear header 13. You may do it.

  As shown in FIG. 12, a male screw may be provided on the reference pin side and a female screw may be provided on the base side. In the configuration example shown in the figure, a female screw hole 25 is formed in the base portion 24 fixed to the canvas top unit 17, and a convex portion protruding from the base end of the reference pin 27 and having a male screw cut on the side periphery. 26 is formed on the reference pin 27. Even in such a case, the reference pin 27 can be easily and reliably fixed and detached. In such a case, since the female screw hole 25 having a length sufficient to securely fix the reference pin is formed in the base portion 24, the base portion 24 is compared with the case where the female screw hole is formed on the reference pin side. (The length of the female screw hole in the extending direction) may be large. Therefore, when the installation space of the base is limited due to interference with other members, it is desirable to adopt a configuration in which a female screw hole is formed on the reference pin side.

  The attachment of the reference pin to the canvas top unit 17 may be performed by a method other than screwing. For example, the reference pin can be formed integrally with the base, and a fragile portion can be provided between the reference pin and the base, and the reference pin can be detached by breaking. It is also possible to attach the reference pin to the base by a snap method. Even in such a case, if the reference pin is detachably provided, the reference pin is detached from the canvas top unit 17 after being attached, so that it is possible to easily ensure the durability against the torsion of the vehicle body.

  In the above embodiment, the reference pin is provided on the canvas top unit side and the reference hole is provided on the vehicle body side. However, the reference pin is provided on the vehicle body side and the reference hole is provided on the canvas top unit side. You can also.
