Referring to fig. 1, a motorcycle frame includes a connection beam 100, a front connection plate 200 and a rear connection plate 300, wherein the front connection plate 200 is connected to the front side of the connection beam 100, the left and right sides of the front connection plate 200 are both bent downward to form front side wings 210, the front portions of the two front side wings 210 are both provided with front connection holes 220 penetrating along the left and right directions, and in practical application, both the two front side wings 210 can be provided with one connection hole; the rear connecting plate 300 is connected to the rear side of the connecting beam 100, the left and right sides of the rear connecting plate 300 are bent downward to form rear side wings 310, a front and rear connecting hole 320 is formed in the rear side wing 310 located on the left side, two rear connecting holes 320 are formed in the rear side wing 310 located on the right side, and rear connecting holes 320 penetrating in the left and right directions are formed in the bottoms of the two rear side wings 310.

It can be seen from the above that, the left and right sides of the front connection board 200 are directly formed by bending downwards, which not only can enhance the structural stability of the front connection board 200 itself, the front connection board 200 and the front side wing 210 located at the left and right sides thereof are surrounded to form a front installation region, which can conveniently install and limit the external engine, the front connection hole 220 can be used for positioning and connection, similarly, the left and right sides of the rear connection piece are directly formed by bending downwards, which enhances the structural stability of the rear connection board 300 itself, and the rear connection board 300 and the rear side wing 310 located at the left and right sides thereof are surrounded to form a rear installation region, which can conveniently install and limit the parking frame of the external equipment, the rear connection hole 320 can be used for positioning and connection, and the connection beam 100 is used for positioning the whole connection to the external machine frame, so that the front connection piece and the rear connection piece are connected to the connection beam 100 directly for connecting the external structure, without additionally installing other accessories, which is more convenient to install and use, and has higher structural stability.

In practical applications, the front connecting plate 200 and the rear connecting plate 300 can be connected to the connecting beam 100 by welding, and since the front wing 210 is directly bent and formed on the front connecting plate 200 and the same rear wing 310 is directly bent and formed on the rear connecting plate 300, the whole assembly is more convenient and simpler.

Since the front side wing 210 has a relatively long length in practical applications, in order to improve the deformation resistance, in the first embodiment, the bottom of the front side wing 210 on the left side is bent leftward to form a left flange 230, and the bottom of the front side wing 210 on the right side is bent rightward to form a right flange 260. The left turned edge 230 and the right turned edge 260 can enhance the bending resistance of the two front side wings 210, and can be attached to a peripheral structure, so that the installation and the positioning are convenient.

When the front connecting plate 200 and the rear connecting plate 300 are positioned and connected to the connecting beam 100, the relative position relationship between the front connecting plate 200 and the rear connecting plate 300 affects the mounting quality of the whole motorcycle frame, and therefore, the mounting accuracy of the front connecting plate 200 and the rear connecting plate 300 needs to be controlled, as shown in fig. 2, in the second embodiment, the front sides of the two rear side wings 310 are both connected with the front positioning sections 330 extending forward, the rear side of the left turned edge 230 and the rear side of the right turned edge 260 are both provided with the positioning concave angles, the two front positioning sections 330 are respectively inserted into the two positioning concave angles, in practical application, a notch can be formed at the rear side of the connection between the left turned edge 230 and the left side wing to form the positioning concave angle, similarly, a notch is formed at the rear side of the connection between the right turned edge 260 and the right side wing to form the positioning concave angle, and notches can also be directly formed at the rear side of the left turned edge 230 and the rear side of the right turned edge 260 to form the two positioning concave angles.

Specifically, the rear connecting plate 300 is matched in the positioning concave angle through the front positioning section 330, and can be connected with the front connecting plate 200, so that the installation of the front connecting plate 200 and the rear connecting plate 300 on the connecting beam 100 is facilitated, the structural stability is enhanced, the positioning accuracy of the front connecting plate 200 and the rear connecting plate 300 on the connecting beam 100 is improved, and the assembling quality of the peripheral structure is further improved.

In order to further improve the installation stability of the front connecting plate 200 and the rear connecting plate 300 on the connecting beam 100, as shown in fig. 3, in this embodiment, two front positioning grooves 211 are disposed on the rear sides of the front side wings 210, the front positioning grooves 211 are arc-shaped, and the front side wall of the connecting beam 100 extends into the front positioning grooves 211 and is attached to the inner wall of the front positioning grooves 211. When the front connecting plate 200 is installed, the front side wall of the connecting beam 100 is clamped into the two front positioning grooves 211, and the front side wall of the connecting beam 100 is attached to the inner wall of the front positioning groove 211, so that the connection between the front side wing 210 and the connecting beam 100 is tighter, the convenience of relative positioning of the front connecting plate 200 and the connecting beam 100 when being connected with each other is further improved, and the stability of a connecting structure between the front side wing 210 and the connecting beam 100 is also improved.

As shown in fig. 4, similarly, rear positioning grooves 311 are formed in the front sides of the two rear side wings 310, the rear positioning grooves 311 are arc-shaped, and the rear side wall of the connecting beam 100 extends into the rear positioning grooves 311 and is attached to the inner wall of the rear positioning grooves 311. When the rear connecting plate 300 is installed, the rear side wall of the connecting beam 100 is clamped into the two rear positioning grooves 311, and the rear side wall of the connecting beam 100 is attached to the inner wall of the rear positioning groove 311, so that the rear side wing 310 and the connecting beam 100 are connected more tightly, the rear connecting plate 300 is positioned more conveniently when being assembled to the connecting beam 100, and the connection between the rear connecting plate and the connecting beam is also more tight.

In some embodiments, the top side of the front connection plate 200 is provided with front mounting holes 240, and the top side of the same rear connection plate 300 is provided with rear mounting holes 340. External connecting pieces such as screws, bolts and the like can be arranged in the front mounting hole 240 and the rear mounting hole 340, so that the arranged structural parts can be connected and fastened better.

In some embodiments, a first mounting ear 250 is attached to at least one of the front side wings 210. Peripheral structural members may interconnect with first mounting ears 250 to enhance the expandability of front wing 210.

In some embodiments, a second mounting ear 110 is attached to the bridge 100. The peripheral structural members may be interconnected to the second mounting ears 110 to improve the expandability of the tie beam 100.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
