Abstract

A kind of front cover for motorcycle, be provided with the portion of removing 2 of proper number in the front portion of protecgulum 1, the weak element 3 that centers on for ring-type on every side, be extruded with protrusion 14 from the inner face side of the portion of removing 2 integratedly towards carriage 6, its front end contacts with the end face of carriage 6 on being installed in head pipe 5, the portion of removing 2 brute forces of protecgulum 1 push the Outboard Sections of weak points 3 relatively, because the end face butt of protrusion 14 front ends and carriage 6, so the portion of removing 2 is separated with on every side protecgulum 1 at weak point 3, take down this and remove portion 2, form mounting hole.

Description

Front cover for motorcycle

The present invention relates to a kind of can be at the front cover for motorcycle of mounted on surface basket.

Real fair 3-1352 communique discloses a kind of mounting structure, its be on the protecgulum of topped frame part by after be processed to form mounting hole, the basket and the frame part that utilize the bolt that passes this mounting hole will be attached on the front cover surface couple together.

, above-mentioned the sort of protecgulum is not established mounting hole at the beginning, in the time will adorning basket, carries out back processing, so must use cutting tool etc. to form mounting hole, at this moment needs prudent operation, with avoid cutter damage mounting hole around.Thereby this job requirements is very skilled, and efficient is lower.

The present invention puts forward in view of the existing problem of above-mentioned prior art, in order to address the above problem, and the front cover for motorcycle that the present invention relates to, its topped frame part is formed for installing the mounting hole of basket on its surface; It is characterized in that, be provided with the portion of removing of stopping up with the mounting hole considerable part, and the weak point of the ring-type that around this portion of removing, forms, simultaneously, being provided with protrusion, this protrusion forms one with the portion of removing, and contacts with frame part.

When forming mounting hole for basket is installed, the portion of removing relatively pushes the protecgulum of the Outboard Sections of weak point to the frame part direction.So, the front end and the frame part butt of the protrusion that becomes one with the portion of removing, break, thereby, if remove the portion of removing, just form mounting hole.

Accompanying drawing is represented embodiments of the invention, wherein:

Fig. 1 is the amplification profile along the A-A line of Fig. 3 of state before the mounting hole on the protecgulum of expression embodiment forms,

Fig. 2 be the expression embodiment protecgulum on the mounting hole forming process with the cooresponding figure of Fig. 1;

Fig. 3 is the exploded perspective view of the mounting structure of basket among the expression embodiment;

Fig. 4 is the amplification profile along the A-A line of Fig. 3 of the installing condition of basket among the embodiment.

With reference to the accompanying drawings, embodiments of the invention are described.

Fig. 1-Fig. 4 represents one embodiment of the invention.

In Fig. 3 and Fig. 4, the front portion of protecgulum 1 is formed with the portion of removing 2 of proper number, and this is removed around the portion 2 annularly around weak point 3 is arranged, and makes a distinction with the other parts of protecgulum 1.

Remove portion's 2 topped mounting holes 4, form one with protecgulum 1.Protecgulum 1 topped its inboard frame part that is provided in, frame part are provided with steering shaft by head pipe 5 therebetween and the carriage of giving prominence to toward protecgulum 1 direction thus 6.

Form through hole 7 at the end face of carriage 6 with removing the part that portion 2 faces, be provided with welded nut 8 around this through hole 7.

If take down the portion of removing 2, just form mounting hole 4, as can be seen from Figure 4, a part of embedding skewer of sleeve pipe 9 is in this mounting hole 4, and the one end contacts with the end face of through hole 7 carriage 6 on every side.

The other end of sleeve pipe 9 and basket 10(Fig. 3) stay 11 contact, on this stay 11, be provided with through hole 12, the front end of bolt 13 enters through hole 7 by through hole 12 and sleeve pipe 9, is connected with welded nut 8, like this, basket 10 anterior face along protecgulum 1 are mounted.

As shown in Figure 1, before mounting hole 4 formed, the inner face side from the portion of removing 2 that is positioned at through hole 7 the place aheads was being given prominence to the protrusion 14 that forms one towards carriage 6, and its front end contacts with the end face of carriage 6.

The overhang of protrusion 14 is the setting gap d that forms between the end face of protecgulum 1 and carriage 6.

Remove portion 2 in order to take this away, as can be seen from Figure 2, to powerful pushing weak point 3(Fig. 1 of the portion of removing 2 of protecgulum 1) Outboard Sections.

So, remove the peripheral part elastic deformation of portion 2 in the protecgulum 1, be pushed to head pipe 5 directions, remove portion 2 owing to the front end of its protrusion 14 and the end face butt of carriage 6, so can not elastic deformation.

Therefore, weak point 3(Fig. 1) be fractured into 3a, 3b, remove portion 2 and separate with protecgulum 1 at weak point 3, form mounting hole 4(Fig. 4), the otch better appearance.

At this moment, the influence of weak point 3 fracture is difficult to arrive the heavy section of protecgulum 1 on every side, so, damage not worrying resembling in the past mounting hole 4 around.And, because as long as pushing protecgulum 1 just can form mounting hole 4, so operation is simple and rapid.

In addition, basket is not installed at 10 o'clock, the portion of removing 2 is kept intact, owing to do not form mounting hole 4, so can keep outward appearance good.And weak point 3 also produces a kind of pattern effect.

The front cover for motorcycle that the present invention relates to is provided with the weak point that stops up with the portion of removing of mounting hole considerable part and the ring-type that forms around this portion of removing, simultaneously, be provided with protrusion, and it forms as one with the portion of removing, and contacts with frame part.

Therefore, when forming mounting hole for basket is installed, as long as the portion of removing relatively earlier is with the past body part direction pushing of the protecgulum of weak point Outboard Sections, just can make the portion of removing in the fracture of weak point and protecgulum and be removed, so, the mounting hole of better appearance around forming, operation is easy and rapid, improves operating efficiency.And not worrying resembling in the past because of around the cutting tool damage mounting hole, do not need the prudent and skilled operation of the sort of in the past requirement.

Claims

1, a kind of front cover for motorcycle, topped frame part is along the surperficial mounting hole that is formed for installing basket; It is characterized in that it is provided with and stops up and the portion of removing of mounting hole considerable part and the weak point that is formed on this portion of removing ring-type on every side, simultaneously, is provided with protrusion, this protrusion becomes one with the portion of removing, and contacts with frame part.
