A motorcycle backrest device

Abstract

The invention discloses a motorcycle backrest device. The motorcycle backrest device comprises a backrest body, a connecting frame, a supporting frame, mounting support lugs, bolts, an upper reinforcing rib, a lower reinforcing rib, a supporting pipe and mounting connectors. The backrest body and the connecting frame fix the mounting support lugs together through the bolts, and the mounting support lugs are welded to the connecting frame. A supporting structure formed by machining a round pipe is arranged at the lower end of the backrest body, and the upper reinforcing rib and the lower reinforcing rib are arranged in order to guarantee strength. Meanwhile, as for the device, the supporting pipe and the connecting frame are welded together at an angle of 45 degrees, and thus the rigidity of the device is guaranteed. The backrest body is designed according to the arc of the back structure of the human body and is in a curved surface shape according with the back of the human body, and a passenger feels comfortable. The device has the characteristics of being comfortable, simple in structure and enough in strength and rigidity, has good performance of fitting with a motorcycle, is convenient to install, can be firmly fixed to a pillion seat only with six bolts, and is low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of production and processing of motorcycle accessories, in particular to a motorcycle backrest device. Background technique [0002] Current motorcycle devices, such as ladies motorcycles or mopeds, are not equipped with a back-to-back device. Adding a back-rest device to the back seat of the motorcycle can protect the safety of the people in the back seat, but most of the back-rest devices are too simple in design at present, mainly through The master worker welded an upright device on the iron frame of the back seat in various ways. However, the back of the human body is a curved structure. This kind of upright back device cannot effectively guarantee the force, and the strength and rigidity are not enough. Also uncomfortable, aesthetics is also not enough simultaneously, a kind of design is reasonable in structure, and is comfortable to use, and aesthetics is strong simultaneously, and service life is long, and it ...

[0002] Current motorcycle devices, such as ladies motorcycles or mopeds, are not equipped with a back-to-back device. Adding a back-rest device to the back seat of the motorcycle can protect the safety of the people in the back seat, but most of the back-rest devices are too simple in design at present, mainly through The master worker welded an upright device on the iron frame of the back seat in various ways. However, the back of the human body is a curved structure. This kind of upright back device cannot effectively guarantee the force, and the strength and rigidity are not enough. It is also uncomfortable, and at the same time, the aesthetics are not enough. It is necessary to design a motorcycle back seat with reasonable structure, comfortable use, strong aesthetics, long service life and sufficient rigidity.
