[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combination frame body of a motorcycle, which can be applied to a bicycle, a motorcycle, a bicycle having an internal combustion engine, and a bicycle having an electric motor.

[0002]

[Prior art]

 Currently, the materials used for frame bodies of motorcycles such as bicycles and electric bicycles are metals such as aluminum alloys, titanium alloys and carbon steel, and non-metals such as engineer plastics, polycarbonate, glass fiber and carbon fiber. . In the case of using metals, welding is adopted in the parts method in all cases, and in the case of using non-metals such as carbon fiber and glass fiber, wire or glass thread is wound and laminated to form an adhesive. The method of filling is adopted and made. Since the main members of the frame body made of metal are welded together, the components are complicated, the welding speed is extremely slow, and the material changes easily after welding, causing the risk of increased fracture. When alloys are used, it is necessary to go through processes such as heat treatment, which makes it difficult to grasp the policy technology, increases manufacturing costs, is economically unreasonable, and technically difficult to mass-produce. Frames made of non-metals such as carbon fiber and glass fiber are manufactured by winding a wire or glass thread and filling them with an adhesive. Therefore, the cost is high and the production speed is slow.

[0003] Taking another example of a combination frame body for a two-wheeled vehicle, this is to join a frame joint and a frame pipe by the lateral pipe expansion action of a metal taper pipe. It has achieved its goal of being easy and fast. However, it was difficult to reach the stage of practical use in this type of rapid joining method by joint fitting because the assembly process is complicated and it is limited to the assembly and processing of pipes with a circular cut end.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention The present invention aims to provide a combination type frame body for a motorcycle, which can be manufactured at a lower cost than a conventional frame body for a motorcycle such as an electric bicycle or a bicycle and has a high production speed. To do.

[0005]

[Means for Solving the Problems]

 According to the present invention, the frame body of the vehicle body is composed of two symmetrical left and right half-frame bodies, and the two half-frame bodies are welded, bonded, ultrasonically or screwed together depending on the material used. It is selected, joined, and quickly and easily formed into one piece.

[0006]

[Action]

 INDUSTRIAL APPLICABILITY The present invention is suitable for mass production because the production can be performed quickly without a complicated assembly sequence, the cost is low.

【Example】

 First, referring to the exploded perspective view of the embodiment of the present invention shown in FIG. 1 and the assembled perspective view of FIG. The present embodiment is an example of the structure of a combination type frame body of an electric bicycle and a bicycle two-wheeled vehicle. Mainly, the frame body (1) is divided into two types depending on the material properties and the needs of different structures. Left and right symmetrical half frame bodies (11) and (12). The frame body (1) is manufactured from a metal such as an aluminum alloy, a titanium alloy, carbon steel or a non-metal material such as engineered plastic, polycarbonate, glass fiber or carbon fiber, and the material has a strength of the whole structure. The material is not limited to the above materials as long as it satisfies the requirements to be coded. The feature of the present invention resides in two half frame bodies (11) and (12) having a shape in which the frame body (1) is divided into two (see also FIGS. 3 and 4 at the same time). The two half-frame bodies (11) and (12) can be formed into a hollow shape by combining them like the structure of a general frame body, reducing the overall weight and accommodating a mechanism such as an electric motor and a transmission element. This makes the appearance of the car body simple and beautiful. In principle, the two half-frame bodies (11) and (12) have substantially symmetrical shapes. However, it is not completely symmetrical, and it is designed according to the structural function of each part. Therefore, the two half frame bodies (11) and (12) are integrally molded. For this reason, production and manufacturing are extremely easy and can be performed quickly (as in a manufacturing method such as injection molding). Among them, the left half-frame body (11) is a joint (13) for receiving the steering wheel and the front wheel, a joint (14) for receiving the saddle, a joint (15) for receiving the pedal, and a pedal (15) as well as a conventional electric bicycle and a bicycle in general. The receiving hole (16) for receiving the rear wheel and the joint pipes (17), (18), (19), (20) of the joints (13), (14), (15) and the receiving hole (16). , (21) and the like. The shapes of the joints, connecting pipes, and the frame body of the vehicle body of the present invention are not limited to this main arrangement structure, and may be appropriately changed according to factors such as different material properties, different demands, and vehicle types used. The right half-frame body (12) is similar to the left half-frame body (11) and corresponds to the joints (22), (23), (24), the receiving hole (25), and the connecting pipe ( 26), (27), (28), (29), and (30), and thus forms a complete joint and connecting pipe in combination with the half frame body (11).

The above two half-frame bodies (11) and (12) are joined by various methods such as spot welding, ring welding, ultrasonic wave, and adhesive due to the difference in manufacturing materials, so that an integral frame is formed. The body (1) is formed (as shown in Fig. 2) and is combined and integrated to be used for the body structure of a motorcycle such as an electric bicycle or a bicycle.

Further, as shown in FIG. 5, through holes (31) are provided on the half-frame bodies (11) and (12) of the present invention so as to be fastened by screws, rivets or other connection methods. The connection may be facilitated to be integrated, and naturally, the connection method of the present invention is not limited to this.

[0010]

[Effect of device]

 According to the present invention, the frame body is made into an integral structure when forming the half frame bodies, so that it is not necessary to completely bond the structures of the joints and connecting pipes of the respective parts by further bonding, welding and fitting. .
