Description

straddle vehicle

technical field

The present invention relates to, for example, a straddle-type vehicle suitable for a scooter or the like.

Background technique

Small motorcycles generally have a structure in which a body frame is completely covered by a cover member.

The cover member includes, for example, a front cover and a leg guard for covering the front and rear of the steering shaft, and includes, at its outer side, footrests for placing feet thereon, and for covering its lower sides. The side cover of the seat plate (see JP-A-6-156349).

For the cover member covering the vehicle body frame, a means of dividing it into multiple pieces is employed in consideration of formability or assembly performance.

When the assembly is completed, the divided cover members cause a height difference or a gap to a connecting line of one cover member and another cover member, resulting in poor appearance. This often creates problems in terms of appearance quality.

Contents of the invention

In view of this point, an object of the present invention is to provide a straddle type vehicle which is high in assembling performance and appearance.

To achieve such an object, a first aspect of the present invention is directed to a straddle-type vehicle characterized by comprising: a vehicle body frame; and at least two cover members assembled together at least partially at end edge portions. At the same time, the body frame is covered. One of the cover members is provided with an engagement groove formed with an insertion port, and the other of the cover members is provided with an engagement protrusion portion that is inserted into the insertion port through the insertion port. It can be engaged with the engaging groove when it is in the engaging groove. The engaging groove is provided with a guide surface for moving the end edge portion of the one cover member closer to the other cover when the engaging protrusion portion is inserted thereinto through the insertion port. The engaging protrusion portion is guided in a direction of the cover member.

With such a configuration, the capping members are fitted together at their end edges by inserting the engaging protrusion portion of the other capping member into the engaging groove of one capping member from the insertion port. In this case, the end edge of one cover member is guided by the guide surface relative to the end edge of the other cover member in the connection direction. As a result, the connection lines obtained can be smooth without gaps. In addition, for the connection operation, insertion only needs to be performed along the insertion port, so the assembly operation is simplified. Therefore this is also highly preferable in view of practicality.

Alternatively, in a preferred example, said guide surface is arranged to extend in a non-perpendicular but oblique direction.

In this case, the cover member is supported upward against gravity, so that the guide surface is kept in contact with the engaging protrusion. As a result, assembly operations can be simplified.

In an alternative configuration, the engaging groove may be provided near the end edge of the terminal edge of the one cover member, and the engaging protrusion portion may be provided near the end edge of the terminal edge of the other cover member. .

With such a structure, when the engaging groove and the engaging protruding portion are fully engaged, the engaging groove and the engaging protruding portion will be placed near the end edge connecting the terminal edge. This then allows the upper and lower closure members to be reliably sealed together at their end edges for a long period of time.

In another alternative configuration, the cover member may extend at least partially in a vertical direction, and the guide surface may be arranged to extend in a substantially horizontal direction.

Such a configuration leads to ease of assembly by moving the cover members in the horizontal direction while supporting the cover members at the time of assembly, thereby achieving easy handling.

Furthermore, the one cover member is a cover member that covers a front portion of the vehicle body frame above the front wheels, and the other cover member is disposed between the front wheels and the vehicle body frame. Cover component.

This achieves a high quality of appearance with the connection lines of the two covers being securely placed in the correct position in the vertical direction.

In another alternative configuration, the guide surface may be arranged to extend along the vehicle.

Such a configuration allows easy assembly while suppressing interference by the steering handle and the like.

Furthermore, a second aspect of the present invention is directed to a straddle type vehicle characterized by comprising a body frame; a vertical cover member covering the body frame; and a horizontal cover member to be coupled to the vertical cover member . The vertical cover member is provided with a snap receiving portion, and the horizontal cover member is provided with a snap support portion to be engaged with the snap receive portion. The bite receiving portion is formed to extend in a substantially horizontal direction.

With such a configuration, dimensional deviation and the like of the formed cover member will be compensated by a substantially horizontal positional relationship, enabling easy cover attachment to the vehicle body frame.

In an alternative configuration, the bite-receiving portion and the bite-supporting portion are arranged in a curved extension when viewed from above.

With such a configuration, the engaged portion can be increased in length due to the curved shape, whereby the coupling strength at the completion of the engaging operation can be increased. Furthermore, this facilitates assembly through the coupling of curved surfaces.

In another alternative configuration, the upper surface of the bite receiving portion may be constituted by an inclined surface whose rear side is higher than the front side.

Such a configuration makes it possible to easily perform a snapping operation when snapping the snap supporting portion, thereby achieving excellent performance in assembly.

In another alternative configuration, the upper surface of the bite support portion may consist of an inclined surface with the front side lower than the rear side.

Such a configuration allows easy snapping operation when snapping the snapping support portion, thereby achieving excellent performance in assembly and improving appearance quality since a small gap is observed at the snapping portion.

Furthermore, a third aspect of the present invention is directed to a straddle type vehicle characterized by comprising a vehicle body frame; and at least two cover members covering the vehicle body while being snapped together at least partially at end edge portions frame. The closure members are each provided with end edges that will snap together, and smooth end edges that form a continuous line. One of the cover members is provided with a rotation receiving portion, and the other of the cover members is provided with a rotation protrusion portion to be engaged with the rotation receiving portion. The rotation receiving portion and the rotation projection portion allow the cover member to be rotatable, and the rotation projection portion and the rotation reception portion are arranged at the end portion of each corresponding cover member. Mesh near the end edge.

Such a configuration obtains an upper end edge line that becomes continuous by the engagement between the rotation receiving portion and the rotation protrusion portion when the front cover member is combined with the rear cover member, thereby resulting in a better appearance. In addition, the snapping of the rotation convex portion to the rotation receiving portion can easily secure the positional accuracy of the upper end edge line.

In another alternative configuration, the cover members are each provided with a restricting portion near at least the rotation raised portion and the rotation receiving portion for restricting movement in a direction perpendicular to the rotation surface, so The cover member rotates on the rotating surface.

With such a configuration, since the restricting portion functions well when the cover member is rotationally positioned, the assembling operation can be performed in a stable manner.

Further, the rotation receiving portion is formed in a substantially semicircular concave shape, and the rotation convex portion is formed in a substantially semicircular shape.

In this way, the two parts are simplified in shape, so that formability is improved with a simplified manufacturing process. Furthermore, due to the fact that the receiving portion and the projecting portion can be easily snapped together, the assembly operation can be easily performed.

Furthermore, the other cover member is arranged above the one cover member. The rotation receiving portion is formed in a substantially semicircular concave shape opening upward, and the rotation convex portion is formed in a substantially semicircular shape extending downward.

With such a configuration, only by assembling the cover member from above, the rotation convex portion can be snapped to the rotation receiving portion through the well-functioning semicircular concave portion, thereby resulting in easy assembly.

Furthermore, easy assembly can be achieved only by moving the cover members in the horizontal direction while supporting the cover members at the time of assembly.

Furthermore, a high quality of appearance can be obtained with the connection line of the cover both vertically securely placed in the correct position.

Furthermore, due to the guide surface, an assembly operation can be easily performed while suppressing interference by a steering handle or the like.

Furthermore, since the snap supporting portion snapped to the snap receiving portion works well, the dimensional deviation etc. of the formed cover member will be compensated by a substantially horizontal positional relationship, so that the cover attachment to the vehicle body frame can be easily performed. Pack.

In addition, both the bite receiving portion and the bite supporting portion are bent so that the length of the bite portion is increased, whereby the coupling strength at the completion of the bite operation can be increased. Furthermore, this facilitates assembly through the coupling of curved surfaces.

Furthermore, due to the configuration including the inclined surface whose opening side is higher, the snapping operation can be easily performed when snapping the snap supporting portion, thereby improving the assembling performance.

In addition, due to the configuration including the lower inclined surface at the tip side, the snapping operation can be easily performed when snapping the snap supporting portion, thereby improving assembling performance and improving appearance quality due to a small gap.

Furthermore, when the front cover member is combined with the rear cover member, an upper end edge line which becomes continuous by the engagement between the rotation receiving portion and the rotation protrusion portion is obtained, thereby resulting in a better appearance. In addition, the snapping of the rotation convex portion to the rotation receiving portion can easily ensure high positional accuracy of the upper end edge line.

Furthermore, since the restricting portion functions well when the cover member is rotationally positioned, the assembling operation can be performed in a stable manner.

Furthermore, both the rotation receiving portion and the rotation convex portion are simplified in shape, so that formability is improved with a simplified manufacturing process. Furthermore, due to the fact that the receiving portion and the protruding portion can be easily engaged with each other, an assembling operation can be easily performed.

Furthermore, only by assembling the cover member from above, the rotation convex portion can be snapped to the rotation receiving portion through the well-functioning semicircular concave portion, thereby resulting in easy assembly.
