Multifunctional frame of underbone motorcycle

Abstract

The invention discloses a multifunctional vehicle frame of a curved beam motorcycle, comprising a main beam tube, a left tube, a right tube, a storage box lock bracket, a front cushion lock bracket, a rear seat cushion lock bracket, a large shelf lock bracket and a rear shelf installation bracket ;The front parts of the left pipe and the right pipe first extend obliquely and downward equidistantly, then extend horizontally forward, and finally extend horizontally to the middle and fix them at the lower end of the main beam pipe; the front parts of the left pipe and the right pipe are installed There is a storage box lock bracket, the front seat cushion lock bracket is installed in the middle of the left tube and the right tube, the rear seat cushion lock bracket, the large shelf lock bracket and the rear shelf installation bracket are installed in the rear of the left tube and the right tube in sequence from front to back, and the rear shelf The mounting bracket is provided with a long seat cushion lock support and a rear seat cushion buckle support. The invention increases the volume of the storage box, and can be installed with a one-stage cushion or replaced with a two-stage cushion, and can also be installed with a small shelf or replaced with a large shelf.

Description

technical field [0001] The invention relates to a multifunctional frame of a curved beam motorcycle. Background technique [0002] Such as figure 1 Shown is the frame structure of the existing curved beam motorcycle, the front parts of the left pipe 100 and the right pipe 200 are directly obliquely downward and fixedly connected to the main beam pipe 300 after moving closer to the middle, which makes the left pipe 100 and the right The space formed at the front of the pipe 200 is too small, and the volume of the storage box installed thereon is also relatively small, so that smaller items can only be placed, and larger items such as safety helmets cannot be placed. [0003] Secondly, the left pipe 100 and the right pipe 200 are only equipped with cushion locking points on the rear and front storage boxes, so only one section of long cushion can be installed, but two sections of cushion cannot be installed, and the commonality of the cushion is poor. [0004] Furthermore, t...

AI Technical Summary

Problems solved by technology

[0002] like figure 1 Shown is the frame structure of the existing curved beam motorcycle, the front parts of the left pipe 100 and the right pipe 200 are directly obliquely downward and fixedly connected to the main beam pipe 300 after moving closer to the middle, which makes the left pipe 100 and the right The space formed at the front of the pipe 200 is too small, and the storage box installed on it is also small in volume, which can only store small items, and cannot store large items such as safety helmets

[0003] Secondly, the left pipe 100 and the right pipe 200 are only equipped with cushion locking points on the rear and front storage boxes, so only one section of long cushion can be installed, and two sections of cushion cannot be installed, and the commonality of the cushion is poor.

[0004] Furthermore, the rear ends of the left pipe 100 and the right pipe 200 are only equipped with a rear shelf support 400, and only small shelves can be installed, and large shelves cannot be directly installed. When installing large shelves, special vehicle frames must be used.
