Seat mounting structure for motor scooter and article storage structure connected thereto

This application is a divisional application with application number: 98104332.1, application date: January 20, 1998, and title of invention: seat installation structure of a small motorcycle and the article storage structure connected to it.

The invention relates to a seat mounting structure of a small motorcycle and an article storage structure connected thereto.

Fig. 37 is a schematic view showing an example of a conventional scooter seat installation structure. This scooter 200 is provided with a large storage section under the seat 201 where items such as helmets can be put in, and the seat 201 can be opened to put them in. or remove items.

The front end of the seat 201 is provided with a seat hinge, and the seat 201 can be turned upside down to the front.

Because above-mentioned seat 201 is that the driver's seat (front seat) and the passenger's seat (rear seat) are set up simultaneously in front and back, namely so-called two-seater, is a slender seat, thereby when making it upside down, there is the same as The problem that the handle cover 202 and the windshield 203 collide will cause hidden dangers such as greater force acting on the seat hinge.

For this reason, once proposed a kind of seat hinge not to be arranged on the front end, but it is moved to the side end in the " miniature motorcycle " of Japanese Patent Publication No. 5-25715, two seats are opened toward the right. motorcycle.

The structure described in the above-mentioned publication is as shown in Fig. 2 of this publication, is that 2 seat hinges (symbols are not recorded) are installed on the side ends, thereby being suitable for longer seats.

However, in Fig. 2 of the above-mentioned publication, there is very little description of the seat hinge. Since the lower hinge plate, which is the main component of the seat hinge, cannot be seen, it is speculated that the lower hinge plate is fastened to the seat hinge with screws or bolts. on the right side of the car cover. And if that is the case, then from the outside, the appearance of the lower hinge plate is not very good, so it is difficult to adopt such a structure.

Therefore, a structure in which the lower hinge plate is fixed on the upper surface of the edge of the storage part is generally adopted. Since the lower hinge plate is required to have a certain rigidity, it is a larger rectangular plate. As can be seen from Fig. 8 (a) below, when such a large lower hinge plate is fixed on the image portion of the storage part, the bearing of the hinge protrudes toward the inside of the storage part, and the opening area of the storage part becomes smaller. narrow.

And any one in the seat described in Fig. 2 of Fig. 37 and above-mentioned publication, in order to make the seat in the fully open position not closed, only have to support with hand, or pole is set, or the fully open holding mechanism that replaces these measures is set.

Though the measure of setting pole is a structurally simple way, setting pole and adjusting pole etc. are also pieces of cumbersome work.

And the fully open holding mechanism that replaces these measures is generally all complicated in structure, also can have the problem that spring is exposed, thereby is not suitable for small and light motorcycle.

Therefore, the first object of the present invention is to ① provide a seat mounting structure capable of overcoming the disadvantages of the front hinge and the side hinge; ② provide a fully open holding mechanism suitable for a small motorcycle.

On the other hand, as the article storage structure of scooter, there is Japanese Patent Laid-Open Report No. Hei 3-21577 "luggage storage device for scooter".

As shown in Figures 1 to 3 of this publication, the above-mentioned technology is to arrange a luggage storage box 38 under the driver's seat 46 (the numbers refer to those described in this publication, and the following is also the same), and form the luggage storage box 38 in front of the driver's seat 46. The extension part 38b covers the upper opening of the luggage storage box 38 and the upper opening of the extension part 38b with the side cover 60, and also covers the upper opening of the luggage storage box 38 with the driver's seat 46 in a switchable manner.

However, in order for the driver to sit comfortably, the width of the driver's seat 46 should neither be too large nor too small. On the other hand, the luggage storage box 38 preferably has as large a storage space as possible. Although the luggage storage box 38 that covers the upper opening with the driver's seat 46 is affected by the width of the seat, the size of the bottom is not limited. If the magnitude of the bottom is large, the storage capacity is large. However, the luggage storage box 38 can only be a box with a bottom, and the width of the bottom cannot be simply increased in consideration of drawing out the mold for molding. Because of this, it is difficult to form the luggage storage box 38 that produces a larger storage space.

Therefore, a second object of the present invention is to provide a technique capable of easily forming a storage box having a large storage space.

In order to achieve the above-mentioned first purpose, the present invention adopts the following technical solutions. Technical solution 1 is a seat mounting structure for a small motorcycle, which is used to cover the upper opening of the storage box for storing safety helmets and other articles by a switchable seat. Among the small motorcycles, it is characterized in that by arranging the seat hinges on the front side of the above-mentioned seats and seeing from the top, the hinge axis is aligned with both the longitudinal axis of the vehicle body and the transverse axis of the vehicle body. It is inclined so that the above-mentioned seat can be opened obliquely forward.

Since the seat hinges are arranged on the side of the front part, a sufficiently wide rear storage part in the width direction can be ensured; when the seat is opened obliquely forward, the rear storage part can be greatly opened, and the rear storage part can be easily moved. Items are put in or taken out.

Technical solution 2 is the seat installation structure of a small motorcycle as described in technical solution 1, characterized in that: viewed from the top, the above-mentioned seat hinge is used as the apex of a triangle, and the first and second hinges are respectively arranged on other apexes of the triangle. 2 Seat locking mechanisms, which lock the above-mentioned seats at 2 positions.

Since the seat can be locked at two places, the locking effect can be enhanced.

Technical scheme 3 is the seat installation structure of the small motorcycle as described in technical scheme 2, characterized in that: the above-mentioned second seat locking mechanism is arranged in the center of the vehicle body, and the action direction of its upper locking pawl is along the width direction of the vehicle. Above-mentioned 1st locking mechanism is configured such that the action direction of its upper lock pawl is along the front and rear direction of the vehicle body, so that the action directions of the two upper lock pawls are substantially perpendicular to each other.

Since the centering of the seat can be carried out by the second seat locking mechanism, the U-shaped accessories on the seat side can be reliably inserted into the first seat locking mechanism through this centering.

Technical solution 4 is the seat mounting structure for a small motorcycle according to technical solution 2 or 3, characterized in that: by unlocking the first seat locking mechanism, the second seat locking mechanism can be unlocked in conjunction with the second seat locking mechanism. linkage unlocking mechanism.

Since the first and second seat locking mechanisms can be unlocked simultaneously with one action, there is no troublesome problem in unlocking.

Technical scheme 5 is the seat installation structure of a small motorcycle as described in technical scheme 1, characterized in that the above-mentioned seat hinge is composed of a lower hinge plate and an upper hinge plate mounted on the above-mentioned lower hinge plate by means of a hinge shaft. Composition, the pin hole for installing the hinge shaft and the arc groove centered on the pin hole are opened on the lower hinge plate, and a concave part is provided at the upper end of the arc groove; on the upper hinge plate A guide protrusion embedded in the above-mentioned circular arc groove is formed on the upper part, and a long pin hole for passing through the hinge shaft is provided; Lead protrusion to fall in the recess of the above-mentioned lower hinge plate of vehicle body side, just can lock seat under the open state.

When opening the above-mentioned seat, the seat can be locked in the opened state by making the guide protrusion of the above-mentioned upper hinge plate moving together with the seat drop into the recess of the above-mentioned lower hinge plate on the vehicle body side.

As long as a concave portion and a long pin hole are attached to the conventional seat hinge, the full-open holding mechanism can be formed, and the seat can be kept fully open with a cheap and simple seat hinge.

In addition, technical proposal 6 made in order to achieve the second object of the present invention is an article storage structure for a small motorcycle, which is used in a small motorcycle that covers the upper opening of the storage box for storing articles such as safety helmets by a switchable seat. Among them, it is characterized in that: the above-mentioned storage box is composed of the upper part of the box and the lower part of the box with a bottom, the upper part of the box is only provided with a bottom in the front half, and extends approximately along the entire length of the seat; the lower part of the box is covered The lower part of the rear half of the upper part of the box is openly combined with the rear half of the upper part of the box and has a bottom; The side wall of the rear half is made into a lower wide inclined wall.

Because with regard to the box top, the front half side wall that has bottom is the inclined wall that makes the top widen, and the rear half side wall that has lower opening is the inclined wall that makes the bottom widen. Thereby the width of the upper opening of the front half can be taken as the maximum size along the width of the front half of the seat. The width of the upper opening of the rear half can be taken as the maximum size along the width of the rear half of the seat. Furthermore, the width of the lower part of the rear half can be formed larger than the width of the opening of the upper part. Again because the box bottom with bottom is not limited by the seat width, it can be increased in coordination with the bottom width in the rear half of the box top. Therefore, not only can ensure that there is a long storage space roughly commensurate with the full length of the seat in the storage box, but also the rear half of the storage space can be formed into a deep and wide large space, and large items such as helmets can be stored. In particular, when the seat is configured as a two-seater, a longer storage space can be easily secured.

And because the inclination (inclination direction) of the side wall at the top of the box changes with the position of the lower opening, the molding die can be easily divided up and down, and as a result, the top of the box can be easily formed.

Because the width of the upper opening of the box top can be taken as the maximum size along the width of the seat, when the upper opening is covered with the seat, the seat can be stably supported by the periphery of the upper opening.

Thus, it is possible to provide a storage box that is easy to form, easily secures a large storage space, and can stably support the seat.

Furthermore, since the storage tank can be molded with an injection mold with high dimensional accuracy, the dimensional accuracy of the storage tank can be improved.

Technical solution 7 is the article storage structure of the small motorcycle as described in the technical solution 6, it is used in the small motorcycle that covers the upper opening of the storage box for storing items such as safety helmets by the switchable seat, its characteristic In that, the rear fender is attached to the storage box by sandwiching one end of the rear fender between the upper portion of the box and the lower portion of the box.

Since the storage box is also used as a mounting member for the rear fender, there is no need to extend the frame long to the rear to install the rear fender as in the past. Therefore, the weight can be reduced by shortening the frame.

Since one end of the rear fender is sandwiched between the upper part of the case and the lower part of the case, the rear fender can be easily and reliably attached to the storage case.

The invention described in technical scheme 8 is an article storage structure for a small motorcycle as described in technical scheme 6 or 7, which is used in a small motorcycle that covers the upper opening of a storage box for storing articles such as safety helmets by a switchable seat. In the car, it is characterized in that: the edge of the upper opening is in the shape of folding the front half outward and folding the rear half inward.

Because the structure of box top is to be positioned at the front half that has bottom, the edge of upper opening is folded outwards, and is positioned at the rear half that has lower opening, the edge of upper opening is folded to the inside. Therefore, the two molds for forming the upper part of the box can be easily separated regardless of whether the upper opening has an edge bent portion or not. Therefore, the upper part of the box can be easily shaped.

Fig. 4 is an exploded oblique view of the seat hinge of the present invention.

The lower hinge plate 61 of the seat hinge 60 is formed by bending a front wall 61d and a rear wall 61e from the front and rear of a bottom plate 61c having bolt holes 61a, 61b, and a pin hole 61f is formed in the front wall 61d, and a pin hole 61f is formed in the rear wall 61e. A pin hole 61g, an arcuate groove 61h centered on the pinhole 61g, and a concave portion 61i depressed downward at the upper end of the arcuate groove 61h are formed.

The upper hinge plate 62 is formed by bending a front piece 62d and a rear piece 62e from the front and back of a top plate 62c having three bolt holes 62a (one is not shown in the figure), and a pin hole 62f is provided on the front piece 62d. 1. The rear plate 62e is provided with a long hole pin hole 62g and a guide protrusion 62h fitted in the arc groove 61h, and a spring hanging portion 62i is formed by bending on the top plate 62c. The elongated pin hole 62g is an elongated hole extending substantially toward the guide protrusion 62h.

The front piece 62d is overlapped on the inner surface of the front wall 61d, and the rear piece 62e is overlapped on the inner surface of the rear wall 61e, so that the pin holes 61f, 62f, 62g, 61g are communicated with each other and the pin shaft 63 is passed through, and the pin shaft 63 The front end and the rear end of the seat are pressed and deformed to prevent the pin shaft 63 from falling off, and the tension spring 64 is erected on the pin shaft 63 and the spring suspension part 62i to complete the combination of the seat hinge 60.

That is, the seat hinge 60 is formed by combining a lower hinge plate 61 with a hinge shaft 63 and an upper hinge plate 62 with a tension spring 64 .

Fig. 5(a), 5(b) is an explanatory view of the action of the seat hinge of the present invention, which corresponds to a sectional view seen from the front. It shows that the lower hinge plate 61c is detachably attached to the hinge bracket 73 with bolts, and the upper hinge plate 62 is detachably attached to the seat 16 side with nuts.

(a) shows the seat hinge 60 in the center-open state, and the guide protrusion 62h is located in the middle of the arc groove 61h.

(b) shows the seat hinge 60 in the fully opened state, the guide protrusion 62h reaches the upper end of the arc groove 61h, and falls into the recess 61i. The hinge shaft 63 is positioned by the rear wall 61e on the rear side, and the rear panel 62e on the front side is shifted downward by the guide protrusion 62h falling into the recess 61i. The feature of this embodiment is that the pin hole of the back piece 62e is formed as a long pin hole 62g so that the vertical movement is not hindered.

That is, since the guide protrusion 62h falls into the recess 61i, the tension of the tension spring 64 increases the active force of the seat's own weight, so even if there is a force in the horizontal direction acting on the guide protrusion 62h, there will be no falling off from the recess 61i. Problem, thereby can keep seat 16 under fully open state.

Fig. 6 is a schematic diagram showing that the seat of the present invention is in a fully open state, and the seat 16 is kept in the state shown in the figure, and in this state, items can be loaded or taken out as shown by the arrow ①.

As shown in Figure 5 (b), since the guide protrusion 62h falls into the recess 61i due to the self-weight of the seat and the tension of the tension spring 64, the tension effect of the tension spring 64 can be smaller, and it is not necessary to pull Stretching spring 64 is done bigger. In Fig. 6, although the front wall 61d and the front piece 62d on the front side are not shown due to the cross-sectional view, the tension spring 64 can actually be accommodated behind the front piece 62d, thereby improving the appearance.

In this way, as long as the recessed portion 61i and the slotted pin hole 62g are added to the previous seat hinge, the fully open holding mechanism can be formed, and the seat 16 can be kept fully open with the cheap and simple seat hinge 60.

7 is a sectional view of the seat pad of the present invention. The seat pad 57 is composed of a base 57a attached to the lower surface of the seat 16 and a lip-shaped pad 57b extending downward from the base 57a. The pad portion 57b is a hollow sealing member inclined outward of the seat 16, and this sealing member is made of an elastic material such as rubber.

Although the sealing surface 51r of the box upper part 51 is a complex shape along the edge of the upper opening, and the circumference is relatively large. However, correspondingly, the pad portion 57b is a lip-shaped pad inclined outward of the seat 16 and is easily elastically deformable. Therefore, the sealing performance of the seat pad 57 can be improved.

8(a), (b) are explanatory diagrams comparing the conventional example with the present embodiment.

(a) shows that the conventional seat 205 opened to the right has a large distance LL from the center CL in the vehicle width direction to the seat hinges 20b, 20b.

(b) shows that the seat 16 opened obliquely according to the present invention has a small distance L from the center CL in the vehicle width direction to the seat hinge 60 .

Because the weight * distance L (or LL) of seat is the moment that seat is opened, so seat 16 of the present invention just can be opened with less moment.

Fig. 9(a) and (b) are also explanatory diagrams comparing the previous example and the present embodiment.

(a) shows the conventional seat 205 opened to the right. Since the two seat hinges 206, 206 arranged at the front and rear protrude greatly toward the side of the middle CL in the vehicle width direction, the storage portion 207 becomes smaller. Although it does not affect the retraction of slender items, it is a structure that presents obstacles to the retraction of larger items with a large width.

(b) shows the seat 16 opened obliquely according to the present invention. When the seat 16 is opened, the rear storage part 51B is opened very large, and on the contrary, the front storage part 51A is opened slightly smaller. Therefore, in this embodiment, the front storage portion 51A is made shallow and the rear storage portion 51B is made deep.

As a result, smaller items can be placed in the front storage portion 51A and larger items can be placed in the rear storage portion 51B, and the storage performance of larger items with a larger width can be improved compared with (a).

10 is a side view of the vehicle frame of the present invention, showing a state in which the storage box 50 is attached to the vehicle frame 2 and the seat 16 is mounted thereon from above. Specifically, the storage box 50 is a storage section that is vertically divided into a box upper portion 51 and a box lower portion 52 at the upper position of the rear frame 2 a, 2 b of the vehicle frame 2 .

This figure also shows that on the rear vehicle frame 2a, 2b of the vehicle frame 2, a door-shaped support frame 72 is installed by means of a gusset plate 71 .
