Abstract
The invention discloses a motorcycle bumper. The motorcycle bumper comprises a frame shape formed by enclosing of a bent main pipe, wherein the main pipe is broken in the middle to form a left bumper part and a right bumper part; a gap which accommodates a forwards inclined pipe is reserved between the left bumper part and the right bumper part; the right end of the upper side of the left bumper part and the left end of the upper side of the right bumper part are connected through a first connecting plate; the right end of the lower side of the left bumper part and the left end of the lower side of the right bumper part are connected through a second connecting plate; both the first connecting plate and the second connecting plate are positioned in front of the forwards inclined pipe and are tightly fixed with the forwards inclined pipe through bolts. The bumper main pipe adopts the structure which is broken in the middle to accommodate the forwards inclined pipe, and the two disconnected parts are connected into a whole through the connecting plates. The thickness of the connecting plates is much less than the diameter of the bumper main pipe, so that on the premise that the damping travel is not reduced or the bumper main pipe is not diminished, the problem of interference between the bumper and a mud baffle plate is effectively solved.
Description
Technical field
The present invention relates to protective device of motorcycle, be specifically related to a kind of bumper/spoiler.
Background technology
Bumper/spoiler is housed on motor bike mostly, and bumper/spoiler can play buffering and supporting role when motor bike is impacted or turns on one's side, and avoids driver's leg to be injured by a crashing object by car body, protects vehicle body not broken simultaneously.
Existing bumper/spoiler supervisor is mostly the integral type frame-shaped construction; by being welded after the tubing bending; before the left and right sides of bumper/spoiler and vehicle frame, inclined tube is almost in the same plane; due to the middle part of front inclined tube gear at bumper/spoiler; make the bumper/spoiler can't straight-line pass, therefore, the middle part of bumper/spoiler can be bent into forward " U " shape usually; in order to pass through around the place ahead to front inclined tube, then by clevis bolt, bumper/spoiler and front inclined tube are fixed together.
For the integral rigidity of assurance thick stick, not yielding, can bear larger impulsive force simultaneously, bumper/spoiler supervisor's diameter is usually more than 20mm, and this all-in-one-piece bumper/spoiler is responsible for, and the space in the front inclined tube the place ahead taken is larger.When front damping compression stroke is maximum, bumper/spoiler and mudwing are interfered, and for avoiding interfering, usually take two kinds of modes to solve: (1) reduces the damping stroke, but can reduce the traveling comfort of car load; (2) reduce bumper/spoiler supervisor's diameter, but can reduce the protection effect of bumper/spoiler.
Summary of the invention
The present invention aims to provide a kind of bumper/spoiler, under the prerequisite that does not reduce bumper/spoiler predominant tube diameter and damping stroke, effectively avoids the interference of bumper/spoiler and mudwing.
For this reason, the technical solution adopted in the present invention is: a kind of bumper of motorcycle, for the left-right symmetric structure, comprise the shaped as frame surrounded by after supervisor (1) bending, and be welded on the reinforced pipe (2) in described shaped as frame, key is: described supervisor (1) disconnects at place, middle position, left and right, form left safety lever part (A) and right bumper/spoiler part (B), and leave the space that holds front inclined tube (3) between left safety lever part (A) and right bumper/spoiler part (B), the right-hand member head of described left safety lever part (A) upside is connected by the first connecting panel (4) with the left end head of right bumper/spoiler part (B) upside, the right-hand member head of left safety lever part (A) downside is connected by the second connecting panel (5) with the left end head of right bumper/spoiler part (B) downside, described the first connecting panel (4), the second connecting panel (5) all is positioned at the place ahead of front inclined tube (3) and tightens together by bolt (6) and front inclined tube (3).
Be preferably, described the first connecting panel (4), the second connecting panel (5) are stamping forming sheet metal component; The left and right sides of described the first connecting panel (4) is provided with the first flange (4a), and be weldingly connected by described the first flange (4a) and the right-hand member head of left safety lever part (A) upside, the left end head of right bumper/spoiler part (B) upside, the both sides up and down of described the first connecting panel (4) are provided with the second flange (4b); The left and right sides of described the second connecting panel (5) vertically is wrapped on front inclined tube (3) after bending backward, the left end head of the right-hand member head of described left safety lever part (A) downside, right bumper/spoiler part (B) downside is welded with respectively vertical adapter plate (7), described adapter plate (7) is positioned at the outside of the second connecting panel (5) bending part, and described bolt (6) tightens together adapter plate (7), the second connecting panel (5) and front inclined tube (3).First, second connecting panel adopts sheet metal component punch forming, and intensity is high, low cost of manufacture, precision are high; The first connecting panel adopts flange and left and right bumper/spoiler partly to weld, and has increased bonding area, has improved the reliability of welding, simultaneously, adopts the structure of upper and lower flange, has further improved the intensity of the first connecting panel; The second connecting panel adopts mode the clenched bolt of flange parcel to be connected with front inclined tube, fully different from the frame mode of the first connecting panel, has increased equally the reliability of intensity and connection.
Further, also be provided with two engine suspension holes (5a) of arranging up and down on the bending part of described the second connecting panel (5), described engine suspension hole (5a) is positioned at the rear of front inclined tube (3).The second connecting panel also, as hanging driving engine, has given the second connecting panel new function, makes complete vehicle structure more compact.
Beneficial effect of the present invention: the bumper/spoiler supervisor is disconnected from middle part, for holding front inclined tube, then by connecting panel, two parts of disconnection are connected as a single entity.Because the thickness of connecting panel is far smaller than bumper/spoiler supervisor's diameter, therefore do not reducing the damping stroke or reducing under bumper/spoiler supervisor's prerequisite, effectively solve the interference problem of bumper/spoiler and mudwing, thereby effectively guaranteed the traveling comfort of car load driving and the protection effect of bumper/spoiler.
The accompanying drawing explanation
Fig. 1 is the front elevation after the present invention and front inclined tube are installed.
