CN203601468U - Anti-interference bumper for motorcycle - Google Patents

Abstract

The utility model discloses an anti-interference bumper for a motorcycle. The anti-interference bumper for the motorcycle comprises a frame formed by bending a main pipe in a defined mode, the middles of the main pipe in the left-right direction are broken, and a left bumper part and a right bumper part are formed. Gaps accommodating a front oblique pipe are formed 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 with a second connecting plate, and the first connecting plate and the second connecting plate are located in front of the front oblique pipe and fastened with the front oblique pipe through bolts. The middles of the bumper main pipe are broken to accommodate the front oblique pipe, and then the connecting plates are used for connecting the broken two parts into a whole. Due to the fact that the thickness of the connecting plates is far smaller than the diameter of the bumper main pipe, on the premise that shock reduction stroke is not reduced or the bumper main pipe is smaller, the interference problem of the bumper and a mud guard is effectively solved.

Description

Anti-tampering bumpers for motorcycles

technical field

The utility model relates to a motorcycle protection device, in particular to a bumper.

Background technique

Most of the motorcycles are equipped with bumpers, which can buffer and support the motorcycle when it is bumped or rolled over, so as to prevent the driver's legs from being injured by the car body and protect the car body from being damaged.

Most of the existing bumper main pipes are integral frame structures, which are welded after bending the pipes. The left and right sides of the bumper are almost on the same plane as the front inclined pipe of the vehicle frame. The middle part prevents the bumper from passing through in a straight line. Therefore, the middle part of the bumper is usually bent forward into a "U" shape so as to pass around the front of the front diagonal tube, and then the bumper and the front diagonal tube are fixed by U-shaped bolts together.

In order to ensure the overall rigidity of the bumper, it is not easy to deform, and at the same time can withstand a large impact force, the diameter of the bumper main tube is usually more than 20mm. This kind of integral bumper main tube occupies a large space in front of the front inclined tube. When the compression stroke of the front shock absorber is the largest, the bumper and the fender interfere. In order to avoid the interference, two methods are usually adopted: (1) reduce the shock absorber stroke, but it will reduce the comfort of the vehicle; (2) reduce the shock absorber stroke. The diameter of the main bumper is smaller, but the protective effect of the bumper will be reduced.

Utility model content

The utility model aims to provide a bumper, which can effectively avoid the interference between the bumper and the fender without reducing the diameter of the main body of the bumper and the shock absorbing stroke.

For this reason, the technical solution adopted by the utility model is: a kind of anti-interference bumper used on motorcycles, which is a left-right symmetrical structure, including a frame surrounded by bending the main pipe (1), and welded on The reinforcing tube (2) in the frame, the key lies in: the main pipe (1) is disconnected at the left and right center position to form the left bumper part (A) and the right bumper part (B), and the left bumper part There is a space between the part (A) and the right bumper part (B) to accommodate the front diagonal pipe (3), the right end of the upper side of the left bumper part (A) and the upper side of the right bumper part (B) The left end of the left bumper part (A) is connected with the left end of the lower side of the right bumper part (B) through the second connecting plate (5). Both the first connecting plate (4) and the second connecting plate (5) are located in front of the front inclined pipe (3) and are fastened together with the front inclined pipe (3) by bolts (6).

Preferably, both the first connecting plate (4) and the second connecting plate (5) are stamped sheet metal parts; the left and right sides of the first connecting plate (4) are provided with first flanges (4a ), and welded with the right end of the upper side of the left bumper part (A) and the left end of the upper side of the right bumper part (B) through the first flange (4a), the first connecting plate (4 ) are provided with second flanges (4b) on the upper and lower sides; the left and right sides of the second connecting plate (5) are bent vertically backwards and wrapped on the front inclined pipe (3), and the left bumper part (A) The right end of the lower side and the left end of the right bumper part (B) are respectively welded with a vertical mounting plate (7), and the mounting plate (7) is located on the second connecting plate (5) and bent On the outer side of the part, the bolts (6) fasten the mounting plate (7), the second connecting plate (5) and the front inclined pipe (3) together. The first and second connecting plates are stamped and formed by sheet metal parts, which have high strength, low manufacturing cost and high precision; the first connecting plate is welded with the left and right bumpers by flanging, which increases the welding area and improves the welding efficiency. Reliability. At the same time, the upper and lower flanging structure is adopted to further improve the strength of the first connecting plate; the second connecting plate is wrapped by flanging and combined with bolts to connect with the front inclined pipe, which is completely consistent with the structure of the first connecting plate. Different, also increases the strength and reliability of the connection.

Further, two engine suspension holes (5a) arranged up and down are also provided on the bent part of the second connecting plate (5), and the engine suspension holes (5a) are located behind the front inclined pipe (3). The second connecting plate is also used to hang the engine, which endows the second connecting plate with new functions and makes the structure of the whole vehicle more compact.

The beneficial effect of the utility model is that the bumper main pipe is disconnected from the middle to accommodate the front inclined pipe, and then the two disconnected parts are connected into one body through the connecting plate. Since the thickness of the connecting plate is much smaller than the diameter of the bumper main tube, the interference problem between the bumper and the fender is effectively solved without reducing the shock absorption stroke or reducing the bumper main tube, thereby effectively ensuring The driving comfort of the whole vehicle and the protective effect of the bumper.
