As an embodiment, the frame 11 shown in fig. 2 and 3 includes a front frame 111, a middle frame 112, and a rear frame 113. The front frame 111 is mainly located at the front of the electric motorcycle 100, the front frame 111 is mainly used for connecting a steering assembly, a headlight assembly and a front suspension assembly of the electric motorcycle 100, and simultaneously, the front wheels in the traveling assembly 14 are indirectly connected to the front frame 111 through the front suspension. The middle frame 112 forms a main body portion of the frame 11, the middle frame 112 is located in the middle of the electric motorcycle 100, and the middle frame 112 is substantially U-shaped. At the same time, the middle frame 112 is located between the front frame 111 and the rear frame 113, and the middle frame 112 also serves to connect the front frame 111 and the rear frame 113 together. The center frame 112 is also provided with mounts for numerous components of the electric motorcycle 100, such as a motor mount, a power mount 1151, and a power mount, all of which are connected to the center frame 112 by welding. The tail frame 113 is mainly located at the tail of the electric motorcycle 100, and the tail frame 113 is mainly used for bearing the rear part of the saddle of the electric motorcycle 100 and forms an integral frame of the saddle lower seat barrel space together with the middle frame 112. The rear wheels in the traveling assembly 14 are also indirectly connected to the rear frame 113 through rear suspensions. Specifically, the front frame 111 includes a main riser 1111 and a front fork 1112, the front fork 1112 being connected to the top of the main riser 1111. The center frame 112 includes two side pipes 1121, the side pipes 1121 extending substantially in the front-rear direction, the two side pipes 1121 being disposed substantially symmetrically with respect to the front-rear direction, the front portions of the side pipes 1121 being connected to the lower portion of the main riser 1111. The tail frame 113 includes a cushion connection portion 1131, and the cushion connection portion 1131 is connected to the rear portion of the side tube 1121. Specifically, the seat cushion connecting portion 1131 may be a mounting plane for connecting the seat cushion, and the seat cushion mounting portion 1131 may be a pipe member having both ends connected to the side pipes. The front frame 111, the middle frame 112 and the tail frame 113 are connected together in the middle by welding to form the main body of the frame 11. Specifically, the front portion of the side pipe 1121 is connected to the lower portion of the main riser 1111 by welding, and the seat cushion connection portion 1131 is connected to the rear portion of the side pipe 1121 by welding. In the present embodiment, as shown in fig. 3 and 4, the side pipe 1121 includes a first side pipe portion 1121a and a second side pipe portion 1121b, the first side pipe portion 1121a extends substantially in the horizontal direction, the second side pipe portion 1121b is disposed substantially obliquely, and the wall thickness of the first side pipe portion 1121a is larger than the wall thickness of the second side pipe portion 1121b. The first side pipe 1121a is the portion of the middle frame 112 with the greatest stress, and increasing the wall thickness of the first side pipe 1121a can increase the strength of the first side pipe 1121a, thereby increasing the overall strength of the frame 11 and improving the overall strength and rigidity of the electric motorcycle 100. The wall thickness of the second side pipe 1121b is substantially the same as the wall thickness of the front frame 111 and the rear frame by increasing the wall thickness of the first side pipe 1121a having a large force, so that the frame 11 can be reduced in weight while the strength of the frame 11 is enhanced.
As an embodiment, as shown in fig. 5, the wall thickness of the first side pipe 1121a is H1. As shown in fig. 6, the wall thickness of the second side pipe portion is H2. The ratio of the wall thickness H1 of the first side pipe portion 1121a to the wall thickness H2 of the second side pipe portion 1121b is 1.4 or more and 2.1 or less. In this embodiment, the first side pipe portion 1121a of the center frame 112 is thickened such that the thickness of the first side pipe portion 1121a is greater than the other portions of the center frame 112, in order to solve the problem of a decrease in frame strength due to a lightweight frame design. When the wall thickness of the first side pipe portion 1121a is increased little, the strength of the first side pipe portion 1121a is increased only a little, and the overall strength of the frame 11 cannot be ensured. On the other hand, when the wall thickness of the first side pipe portion 1121a increases more, the improvement of the overall strength of the frame 11 is limited, but the overall weight of the frame 11 is increased, which adversely affects the flexibility of the electric motorcycle 100. As shown in fig. 5 and 6, the ratio of the wall thickness H1 of the first side pipe portion 1121a to the wall thickness H2 of the second side pipe portion 1121b is 1.4 or more and 2.1 or less, so that the rigidity and strength of the center frame 112 can be increased while satisfying the light weight requirement as much as possible. Further, the ratio of the wall thickness H1 of the first side pipe portion 1121a to the wall thickness H2 of the second side pipe portion 1121b is 1.5 or more and 2.0 or less. Further, the wall thickness of the first side pipe portion 1121a and the wall thickness of the second side pipe portion 1121b are set to 1.5 or more and 2.0 or less, which can better satisfy the requirements of the middle frame 112 for weight saving, frame strength and frame rigidity.
As one embodiment, as shown in fig. 7, the side tube 1121 further includes a frame liner 1121c connected to the first side tube portion 1121a, the frame liner 1121c being disposed within the first side tube portion 1121a. For a specific method for increasing the strength of the first side tube portion 1121a, a frame lining 1121c may be disposed on the inner side of the first side tube portion 1121a of the middle frame 112, so that the whole body formed by the first side tube portion 1121a and the frame lining 1121c has a larger wall thickness than the second side tube portion 1121b, thereby achieving the purpose of enhancing the strength and rigidity of the first side tube portion 1121a, and finally achieving the purpose of enhancing the strength and rigidity of the frame under the requirement of meeting the light weight. After the frame liner 1121c is connected to the first side tube portion 1121a a, the first side tube portion 1121a is bent to form a corresponding shape together with the frame liner 1121 c. Specifically, the frame liner 1121c is connected to the inner wall of the first side tube portion 1121a by welding.
In one embodiment, the frame liner 1121c is a pipe member, and the outer diameter of the frame liner 1121c is substantially equal to the inner diameter of the first side pipe portion 1121a. When the frame lining 1121c is a pipe, it can be better fitted into the first side pipe 1121a, and the wall thickness of the first side pipe 1121a can be increased uniformly, so that the first side pipe 1121a is ensured to have a uniform structure and uniform strength, and the problem caused by the non-uniform strength of the first side pipe 1121a is avoided. When the outer diameter of the frame liner 1121c is substantially equal to the inner diameter of the first side tube portion 1121a, the gap between the frame liner 1121c and the first side tube portion 1121a is small, even 0, and the frame liner 1121c and the first side tube portion 1121a have better bonding ability. After the frame lining 1121c and the first side tube 1121a are welded, a more stable whole can be formed, that is, the first side tube 1121a has better stability and is not easy to peel.
As an embodiment, as shown in fig. 8, the sum of the wall thickness of the frame lining 1121c and the wall thickness of the first side tube portion 1121a is H3. The ratio of the sum H3 of the wall thickness of the frame liner 1121c and the wall thickness of the first side tube portion 1121a to the wall thickness H2 of the second side tube portion 1121b is 1.4 or more and 2.1 or less. Further, the ratio of the sum H3 of the wall thickness of the frame lining 1121c and the wall thickness of the first side tube portion 1121a to the wall thickness H2 of the second side tube portion 1121b is 1.5 or more and 2 or less. When the thickness of the frame lining 1121c is small, the strength of the first side pipe portion 1121a is limited, and the overall strength of the frame 11 cannot be ensured. On the other hand, when the thickness of the frame lining 1121c is large, the improvement of the overall strength of the first side pipe portion 1121a is limited, but the weight of the first side pipe portion 1121a is increased, and the overall weight of the frame 11 is increased, which adversely affects the flexibility of the electric motorcycle 100.
In one embodiment, the first side pipe 1121a and the second side pipe 1121b are integrally formed. In addition to the fact that the thickness of the wall of the first side pipe portion 1121a may be increased by the previous lining, other methods may be used to make the thickness of the wall of the first side pipe portion 1121a larger than the thickness of the wall of the second side pipe portion 1121b. Specifically, the first side pipe portion 1121a and the second side pipe portion 1121b are integrally formed, and the wall thickness of the second side pipe portion 1121b is reduced by adopting a process such as pipe drawing or cutting in the forming process, so that the wall thickness of the first side pipe portion 1121a is larger than that of the second side pipe portion 1121b, thereby not only realizing the light weight treatment of the second side pipe portion 1121b, but also ensuring the strength and rigidity of the first side pipe portion 1121a. The first side pipe portion 1121a and the second side pipe portion 1121b having different wall thicknesses may be integrally formed by casting or the like.
As one embodiment, the middle frame 112 is connected to both sides of the front frame 111. The middle frame 112 includes two side pipes 1121 symmetrically arranged in the front-rear direction, and the two side pipes 1121 of the middle frame 112 are connected to two sides of the front frame 111, so that the connection area between the middle frame 112 and the front frame 111 can be increased, the connection strength and connection rigidity between the middle frame 112 and the front frame 111 can be enhanced, and the rigidity and strength of the frame of the electric motorcycle 100 can be further ensured.
As an embodiment, as shown in fig. 9, the frame 11 further includes a reinforcement member 114, a portion of the reinforcement member 114 is connected to the middle frame 112, another portion of the reinforcement member 114 is connected to the front frame 111, and the reinforcement member 114, the middle frame 112, and the front frame 111 enclose the triangular region 101. The reinforcement 114 is provided between the front frame 111 and the middle frame 112, and a plurality of triangle structures are formed between the front frame 111 and the middle frame 112 to enhance the connection stability between the front frame 111 and the middle frame 112, and to improve the strength and rigidity of the frame of the electric motorcycle 100. Specifically, the reinforcement 114 has a substantially trapezoidal shape, one side of the reinforcement 114 is connected to the side pipe 1121 of the center frame 112, the other side of the reinforcement 114 is connected to the main riser 1111 of the front frame 111, and the reinforcement 114 is further provided with a weight-reducing hole 1141.
As one embodiment, the frame 11 further includes a frame attachment 115 (shown in fig. 1), and the frame attachment 115 is connected to the first side tube portion 1121a by welding. Further, the frame accessory 115 may be an electrical mount 1151 (shown in FIG. 1), and the frame accessory 115 may also be a drive assembly mount 1152 (shown in FIG. 1). Specifically, in the present embodiment, the drive assembly mount 1152 may be a motor mount. The first side pipe portion 1121a in the present embodiment is thickened, and the welding of the frame attachment 115 to the first side pipe portion 1121a can better resist the deformation of the first side pipe portion 1121a caused by welding, and ensure the dimensional accuracy and structural strength of the first side pipe portion 1121a.
