However, the strength and rigidity of the magnesium-aluminum alloy are poorer than those of steel materials, so that the light non-welded structure keel cannot be put into practical application all the time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome not enough among the prior art, provide a magnesium aluminum alloy bicycle fossil fragments, through the improvement to bicycle fossil fragments and connection structure, make magnesium aluminum alloy material can use on the bicycle, alleviate the weight of bicycle.
The utility model discloses a realize through following technical scheme:
the utility model provides a magnadure bicycle keel, including body frame part and front fork part, the body frame part includes symmetrical left body frame and right body frame, left body frame and right body frame are by fixed connection's upper bracket, the lower carriage, back upper fork and back lower fork constitute, the upper bracket and the lower carriage of left body frame and right body frame pass through the connecting plate and connect, body frame part fixed connection locomotive bowl group respectively, sit the pipe, the trailing axle, the front fork part includes left front fork and right front fork, left front fork and right front fork pass through the connecting pipe and connect, the handlebar is connected on the upper portion of left front fork and right front fork, the wheel axle is connected to the sub-unit connection of left front fork and right front fork.
According to the above technical solution, preferably, the left main frame, the right main frame and the connecting plate of the main frame portion constitute an H-shaped structure.
According to the above technical solution, preferably, the left front fork, the right front fork and the connection pipe of the front fork portion constitute an H-shaped structure.
According to the above technical solution, preferably, the left and right main frames are constituted by a plurality of detachable portions, and the detachable portions are connected by flanges and rivets.
According to the above solution, preferably, the detachable portion is provided with a plurality of differently sized replacements.
The utility model has the advantages that: the structural strength of the bicycle keel is enhanced, so that the magnesium-aluminum alloy can become a detachable keel material of the bicycle, and the weight of the bicycle is reduced.
Drawings
Fig. 1 shows a schematic front view structure diagram of an embodiment of the present invention.
Fig. 2 shows a schematic top view of an embodiment of the present invention.
In the figure: 1. the bicycle comprises a main frame part, a left main frame, a right main frame, a top frame, a bottom frame, a rear upper fork, a rear lower fork, a connecting plate, a headset, a seat tube, a rear axle, a front fork part, a handlebar part, a left front fork, a right front fork, a handlebar part and a front axle part, wherein the main frame part comprises 2, the left main frame, 3, the right main frame, 4, the top frame, 5, the bottom frame, 6, the rear upper fork, 7, the rear lower fork, 8, the connecting plate, 9, the headset.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model relates to a magnesium aluminum alloy bicycle keel, including body frame part 1 and front fork part, the body frame part includes symmetrical left body frame 2 and right body frame 3, left body frame and right body frame are by fixed connection's upper bracket 4, undercarriage 5, back upper fork 6 and back lower fork 7 constitute, the upper bracket and the undercarriage of left body frame and right body frame pass through connecting plate 8 to be connected, body frame part fixed connection locomotive group 9 respectively, sit pipe 10, trailing axle 11, the front fork part includes left front fork 12 and right front fork 13, left front fork and right front fork pass through the connecting pipe and connect, handlebar 15 is connected on the upper portion of left front fork and right front fork, left front fork and right front fork's sub-unit connection front axle 16.
In this embodiment, the main frame part is composed of a left main frame and a right main frame, and the left main frame and the right main frame are connected by a connecting plate, so that the main frame part is structurally reinforced. The front fork part is composed of two independent left front forks and right front forks, replaces the integral front fork of a common bicycle, and enhances the structural strength of the front fork. Meanwhile, as the density of the magnesium-aluminum alloy is smaller, the bicycle adopting the main frame part structure is still lighter than that of a common bicycle.
According to the above embodiment, it is preferable that the left main frame, the right main frame, and the connecting plate of the main frame portion constitute an H-shaped structure. The middle part of left body frame and right body frame is connected to the connecting plate, has avoided the space extrusion deformation between left body frame and the right body frame.
According to the above embodiment, preferably, the left front fork, the right front fork and the connection pipe of the front fork portion constitute an H-shaped structure. The connecting pipe is connected with the middle parts of the left front fork and the right front fork, so that the extrusion deformation of a gap between the left front fork and the right front fork is avoided.
According to the above embodiment, it is preferable that the left and right main frames are constituted by a plurality of detachable portions, and the detachable portions are connected by flanges and rivets. The left main frame and the right main frame can be detached through the structure, and are convenient to clean and replace.
According to the above embodiment, preferably, the detachable portion is provided with a plurality of differently sized replacements. The left main frame and the right main frame change the overall size of the bicycle by replacing the replacement parts with different sizes.
The utility model has the advantages that: the structural strength of the bicycle keel is enhanced, so that the magnesium-aluminum alloy can become a keel material of the bicycle, and the weight of the bicycle is reduced.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
