Description

Motor scooter

The present invention relates to a kind of motor scooter, this car has a toe board that the lower position place is provided with before vehicle seat, and this car can make rider be sitting on the vehicle seat, rather than rides on the vehicle seat.

Motor scooter has a toe board that lower position is provided with before vehicle seat usually, need not ride on the vehicle seat so that rider can be sitting on the vehicle seat, and the position that rider is sat is one of difference main between motor scooter and the common motor bike.

As shown in figure 19, such motor scooter has a unshowned Fuel Tank, and this Fuel Tank connects the rear portion that driving engine in the lower position of same rear portion vehicle body c below vehicle seat is installed in toe board a.In order to inject fuel to Fuel Tank, the anterior c1 of rear portion vehicle body c has a service kit f, and this case has an openable service cover e.On the top of rear portion vehicle body c, the upper space that is included in service kit f has a package bin g, and a helmet and similar article are placed in this package bin.

Referring to Figure 20, service kit f holds fuel filler opening h and light-up plug service ports i who covers with lid j of a Fuel Tank, through port i, and the light-up plug of driving engine is able to installation and maintenance.One instrument such as the light-up plug spanner can be inserted into by this light-up plug service ports i, to safeguard light-up plug.

As shown in figure 21, toe board a has a box-shaped electric box k, and this electric box k is recessed from the plane of toe board, to store battery and corresponding electric elements.This electric box is lived with an openable cap seal.

A bundle conductor that links to each other with battery (a cover binding post and a lead), wire fuse, clamper, coupler (line connector) and analogue are introduced into electric box k.The one big opening m that allows excessive coupler to pass through requires to be bored on the electric box k, and this opening can make electric elements enter electric box.In order to prevent that rainwater, earth and dust from entering by opening m, a bigger rubber grommet n is housed on opening m.

The supporting construction of toe board a is described now.Referring to the planar view of Figure 22 A and the left side view of Figure 22 B, a main car frame pipe p is from the downward-sloping backward extension of head pipe o of vehicle frame, and the back vehicle frame pipe p2 extension that is inclined upwardly backward from the rear end of the levelling pipe p1 of main car frame pipe p.

A horizontally extending crossbeam q of horizontal direction at motor bike is rigidly connected to the front portion of the levelling pipe p1 of main car frame pipe p, and another crossbeam r that extends in horizontal cross is rigidly secured in the rear portion of levelling pipe p1.The horizontal longitudinal extension of a pair of left and right sides strengthening part s also links to each other with right-hand member with the left end of crossbeam q, r respectively.

Part below toe board a has some protruding t such as rib and boss.These projectioies continue to contact with the upper surface of front and back crossbeam q, r and strengthening part s, and like this, the load (weight of rider) that acts on the toe board upper surface is transferred on the vehicle frame.

Yet there is following problems in this design of mini motor bike.

At first, because the opening of the service kit f that forms in the front portion of rear portion vehicle body c often is very little, bring difficulty for the maintenance of light-up plug.When spark is safeguarded, the moving of the edge of opening overslaugh light-up plug spanner of service kit f.

As shown in figure 20, light-up plug service ports i opens vertically upward.Therefore in the vehicle body c of rear portion, check light-up plug from top.This structural requirement has enough spaces on light-up plug in the vehicle body c of rear portion.In addition, if light-up plug can not be adjusted upward in the vehicle body c of rear portion, service kit will correspondingly down be provided with, and package bin g is correspondingly enlarged.Yet, in fact, must guarantee the service clearance of light-up plug, so package bin g is limited in less space.

Service kit f has service cover e, in case impurity, as dust or rainwater through the fuel inlet of Fuel Tank enter and with the fuel mix of the inside.In addition, for service cover e, service kit f also has the lid j that is used for light-up plug service ports i, to prevent impurity, infiltrates through light-up plug service ports i such as dust or rainwater.The lid that the light-up plug service ports is set in very narrow service kit f makes maintenance efficiency reduce.

The opening of the electric box k that forms on toe board a need come airtight with bigger in addition lid.Except this lid, because motor scooter needs other lid or comprises the cover piece that covers e and j, its part count is increased.Manufacturing step correspondingly is increased, and manufacturing cost correspondingly is enhanced.

Because as the ability of earth and dust, also there are other problem in parts waterproof ability in electric box k and electric box k draining and discharge impurity, electric box k has out the opening on toe board a.Promptly use lid closely to close opening, rainwater is reached and the same level of toe board when serious dropping on raindrop on the toe board a in the rain inevitably.Like this, water can infiltrate electric box k, says further, and rainwater also can carry sand or earth and enter electric box k.

Have a drain gutter on the lower surface of electric box k, by this hole, rainwater is easily discharged.Sand, earth or analogue can not all be discharged, and its partial product is on the toe board between battery and the electric box k bottom interior surface.These sands or the earth electric elements of will making dirty as battery, and makes the battery wearing and tearing owing to repeat to bear vibrations in the process of riding.

The electric box k of some type has a padded coaming that is bonded on the bottom interior surface, to prevent the battery wearing and tearing.Yet these padded coamings remain in the electric box k sand or earth, can encounter difficulties when drain gutter is discharged it with water.Use padded coaming will cause part count to increase, the cost of manufacture of motor scooter is increased.

Cell terminal and coupler insert electric box k by intake m, and for waterproof and dust protection, this mouthful m needs a bigger grommet n.The common price height of big grommet n like this, and the control of its rigidity is difficult, this grommet are rigidity, and increasing its seal ability, so its installation on electric box is difficult, and the weight of car is increased.

In addition, as the protruding t that supports toe board a, during as boss and rib and toe board a formation one, indentation (indenture that resin material forms in the cure shrinkage process) is formed on the upper surface of toe board a in bottom and the corresponding position of protruding t, because this projection t has than the big volume in other positions of toe board, makes that these indentation profiles are not attractive in appearance.

Because protruding t continues to be pressed in crossbeam q, on r and the strengthening part s, protruding t rapid wearing, and the load that acts on the toe board a can not transmit or transfer on the vehicle frame effectively.

First purpose of the present invention provides a kind of motor scooter, wherein, can carry out effective maintenance operation of light-up plug, the package bin of a large space can be set under vehicle seat, number of components and in the manufacturing process of motor scooter manufacturing step be reduced, and manufacturing cost reduces.

Second purpose of the present invention provides so a kind of motor scooter, wherein, the water resistance that is arranged on the electric box below the toe board is enhanced, the elimination ability of analogues such as the draining of electric box, spoil disposal, row's sand is enhanced, the battery of installing in electric box has been avoided the wearing and tearing by earth, sand and analogue generation, enter the bundle conductor in the electric box, coupler and analogue are water repellant, the grommet of dust protection makes less, reducing its cost and to guarantee its rigidity, and the outward appearance of toe board is enhanced.

The 3rd purpose of the present invention provides a kind of motor scooter, and this car can make the load that acts on the toe board transfer on the vehicle frame effectively, and this transfer is long.

Be used to realize a kind of motor scooter of above-mentioned purpose, its component parts comprises: the toe board that lower position is provided with before vehicle seat, and package bin that forms in the vehicle body of rear portion below vehicle seat and one have at least one swing engine installation that is contained in the front end below the package bin; It is characterized in that, one light-up plug is installed in the front end of swing engine installation, so that check light-up plug from the front, be provided with between swing engine installation and the toe board angledly, so that the extended line of light-up plug intersects with toe board from following, one through hole is offered in the extended line and the toe board intersection of light-up plug, to allow the light-up plug service tools from this through hole, to insert, the electric box that one opening that is used to hold electric elements makes progress is offered near the through hole on toe board, and a service cover removably tightly covers electric box and through hole.

In above-mentioned structure, when the maintenance light-up plug, a maintenance instrument can be inserted into by the through hole that forms on the toe board upper surface as the light-up plug spanner.For the obtainable space of maintenance operation is so that the maintainer finishes maintenance work in a comfortable position.Therefore, the efficient of light-up plug maintenance operation is enhanced.The position that the swing engine installation is installed light-up plug is arranged on below the vehicle seat of rear portion vehicle body, and this position only accounts for very little space in the vehicle body of rear portion.Therefore, in the vehicle body of rear portion, the space of package bin is increased.In existing motor scooter, the lid of the lid of sealing electric box and sealing light-up plug service ports separates.According to the present invention, mono-service cover sealing electric box and light-up plug service ports, therefore, the quantity of lid is reduced.This layout is reduced the number of components of motor scooter and manufacturing step, thereby the cost of motor scooter is reduced.

In motor scooter of the present invention, service cover has a protection walls between electric box and through hole, so that electric box and through hole are separated, and prevents that earth, rainwater and analogue via through holes from entering electric box.This structure has prevented that effectively earth, rainwater or analogue via through holes from entering electric box, and has improved the water resistance of electric box, has therefore protected the electric elements in electric box.The protection walls that forms on service cover is preventing that the dust via through holes from entering the effect that is equivalent to two lids aspect the electric box, therefore, number of components is reduced.

In existing motor scooter, be used for covering at the lid of the electric box of toe board and another lid of being used to cover the light-up plug maintenance part is provided with respectively.In motor scooter 1 of the present invention, toe board 9 has close through hole 20 and is used to keep in repair the electric box 22 that the light-up plug opening makes progress, and service cover 11 removably covers electric box 22 and through hole 20.This structure decrease the number of lid, therefore reduced part count, and the manufacturing step of motor scooter 1, the cost of motor scooter is reduced.

Because service cover 11 has the protection walls 48 that separates electric box 22 and through hole 20, therefore, earth, rainwater and other dusts can not enter electric box 22 by via through holes 20.This structure has increased the water resistance of electric box 22, and can protect the electrical equipment in the electric box 22 safely.Prevent the dirt via through holes enter electric box aspect, the service cover 11 that has protection walls is equivalent to two lids, like this, single lid 11 is about the same in the effect of two lids, therefore, the present invention helps to reduce part count.

Electric box 22 has

drain gutter

37,38 and some ribs 40 at its bottom interior surface 22a.The longitudinal direction of ribs 40 points to drain gutter 37.Ribs 40 makes battery 32 float from bottom interior surface 22a, makes battery 32 directly produce wearing and tearing facing to inside face 22a to prevent sand or earth between battery 32 and inside face 22a, and therefore, the loss of battery 32 is excluded.Even in the water intrusion electric box 22, water will flow to drain gutter 37 along ribs 40.Because ribs 40 is as guiding water into drain gutter 37, water is promptly drained.In this case, earth and the sand that is carried by water can not stop that earth and sand are drained by drain gutter 37 with water by supported rib 40.

When motor scooter 1 by its supporting leg 39 fixedly during vehicle body, the downward-sloping side of the lower surface 22a of drain gutter 37 close electric boxs 22.Therefore, when motor scooter 1 was stopped, the bottom interior surface 22a of electric box 22 tilted, and drain gutter 37 is cut in the downward-sloping side of bottom interior surface 22a.Like this, the discharge that is cooled of the water in electric box 22.

Electric box 22 has inside enlarged 51.The upper surface 51a of this enlarged 51 matches with the lower surface of service cover 11.Enlarged 51 has opening 52.The opening 52 of lead wire bundle 53 is made of two continuous openings, and these two openings are at the upper shed 52a of upper surface 51a and the side opening 52b on side surface 51b.The size of opening 52a is greater than the size of opening 52b.Bundle conductor 53 passes elastomeric grommet 55, and this ring 55 is stuck in the side opening 52b.The top of grommet 55, and the upper surface 51a of enlarged 51 matches with service cover 11.This structure needn't make coupler (line connector) pass side opening 52b, and this opening 52b seals mutually with grommet 55.Compared with prior art, this side opening 52b does lessly, and correspondingly grommet 55 is also less.Therefore, the cost of grommet 55 is reduced, and the rigidity of grommet 55 also is guaranteed easily.

The foot's anti-slip tank 49 that is used for rider is opened in the upper surface of rear leg backplate 10 and service cover 11, and backplate 10 and service cover 11 constitute toe board 9, and the anti-slip tank 49a of foot is formed around service cover 11.Almost can't see boundary line between rear leg backplate 10 and the service cover 11 by anti-slip tank 49a.At first sight, the service cover 11 of installing on toe board 9 can not be recognized.This spline structure makes the profile of motor scooter 1 more attractive in appearance.
