Detailed Description
Referring to fig. 4, 5 and 6, the motorcycle frame according to the embodiment of the present invention includes a main pipe unit 2, two side pipe units 3 respectively connected to left and right sides of the main pipe unit 2, a reinforcement unit 4 connected to the main pipe unit 2, and an accommodating unit 5.
The main pipe unit 2 includes a head pipe 21 for pivotally mounting a handle 200, and a slot connecting mechanism 22 for connecting the head pipe 21 and the reinforcing unit 4. The slot attaching mechanism 22 includes a body 221 connected to the head pipe 21, and a slot attaching member 222 connected to the body 221. For ease of illustration, the handle 200 is shown only in fig. 5.
The side pipe units 3 are connected to the left and right sides of the main body 221 of the tank connecting mechanism 22, and each side pipe unit 3 includes a main side pipe 31 connected to the tank connecting mechanism 22 of the main pipe unit 2, and a sub side pipe 32 provided to the main side pipe 31.
The main side pipe 31 has a lower extension 311 extending downward from the connecting mechanism 22 of the main pipe unit 2, a straight section 312 extending substantially horizontally rearward from the lower extension 311, and an upper extension 313 extending rearward and upward from the straight section 312, and both ends of the secondary side pipe 32 are connected to the lower extension 311 and the upper extension 313, respectively, and spaced apart from the straight section 312.
The reinforcing unit 4 includes a central reinforcing pipe 41 connected to the head pipe 21 of the main pipe unit 2 and extending downward, a first reinforcing pipe 42 connected to an end of the central reinforcing pipe 41 opposite to the main pipe unit 2 and having a substantially inverted U-shape, two reinforcing members 43 respectively connecting the sub-side pipe 32 of each side pipe unit 3 and the first reinforcing pipe 42 in a transverse direction, and a reinforcing plate 44 connecting straight sections 312 of the main side pipes 31 of the side pipe units 3.
The central reinforcing pipe 41 is connected to the slot 222 of the slot connecting mechanism 22 and has a first connecting end 411 connected to the head pipe 21 of the main pipe unit 2 and a second connecting end 412 connected to the first reinforcing pipe 42 opposite to the first connecting end 411. And opposite ends of the first reinforcing pipe 42 are respectively connected to the straight sections 312 of the main side pipes 31 of the side pipe units 3, and the second connecting end 412 of the central reinforcing pipe 41 is higher than the secondary side pipe 32 of the side pipe unit 3 with respect to the ground G.
The reinforcing plate 44 is connected to the side of the straight section 312 of the main side pipe 31 facing the ground G, and the reinforcing plate 44, the first reinforcing pipe 42 and the straight section 312 of the main side pipe 31 of the side pipe unit 3 cooperate to define an installation space a.
The accommodating unit 5 includes a hollow oil tank 51 installed in the installation space a, and an oil inlet 52 communicating with the oil tank 51 and protruding between the lower extension 311 of the main side pipe 31 of the side pipe unit 3 and the central reinforcing pipe 41 of the reinforcing unit 4.
Since the height of the second connection end 412 of the central reinforcing pipe 41 with respect to the ground G is higher than the height of the subsidiary side pipe 32 of the side pipe unit 3 with respect to the ground G, the space between the lower side of the first reinforcing pipe 42 and the straight section 312 of the main side pipe 31 of the side pipe unit 3 can be sufficiently utilized, improving the space utilization.
In summary, the motorcycle frame of the present invention can improve the space utilization by making the design that the height of the second connecting end 412 of the central reinforcing pipe 41 with respect to the ground G is higher than the height of the secondary side pipe 32 of the side pipe unit 3 with respect to the ground G, and by making the space between the lower side of the first reinforcing pipe 42 and the straight section 312 of the primary side pipe 31 of the side pipe unit 3 sufficiently applicable, so that the object of the present invention can be achieved.
In addition, the structural strength of the head pipe 21 can be improved by connecting the head pipe 21 and the center reinforcing pipe 41 by the grooving mechanism 22. The two reinforcing members 43 respectively connecting the sub-side pipe 32 of each side pipe unit 3 and the first reinforcing pipe 42 can enhance the bonding strength between the first reinforcing pipe 42 and the sub-side pipe 32. By reusing the reinforcing plate 44 connecting the straight sections 312 of the main side pipes 31 of the side pipe unit 3, it is possible to not only improve the strength of the main side pipes 31 of the side pipe unit 3 but also protect the oil tank 51. Finally, the hollow oil tank 51 is installed in the installation space a with the oil inlet 52 projecting between the lower extension 311 of the main side pipe 31 of the side pipe unit 3 and the central reinforcing pipe 41 of the reinforcing unit 4, and the space can be further sufficiently utilized to improve the space utilization.
The above description is only an example of the present invention, and not intended to limit the scope of the invention, and all simple equivalent changes and modifications made according to the claims and the contents of the patent specification are still within the scope covered by the present invention.
