[0026] Reference Figures 1 to 4 This application provides a motorcycle frame, including: a frame body, with a left support 101 and a right support 102 respectively provided on both sides of the frame body, a first protrusion 103 provided on the side of the left support 101 and the right support 102 that are far apart from each other, and a second protrusion 104 provided at the front end of the left support 101 and the right support 102; a foot pedal 200, with a connecting part 210, which is fixedly connected to the first protrusion 103; and a frame cradle, including symmetrically arranged cradle bends 310 and cradle cross tubes 320 disposed between the cradle bends 310, the cradle bends 310 corresponding to the left support 101 and the right support 102 respectively, a connector 330 provided at the rear end of the cradle bends 310, the connector 330 cooperating with the second protrusion 104, and the front end of the cradle bends 310 connected to the front end of the frame body.

[0027] By simultaneously providing a first boss 103 and a second boss 104 on the left bracket 101 and the right bracket 102, not only can the first boss 103 cooperate with the connecting part 210 to realize the installation of the pedal 200, but the second boss 104 can also cooperate with the connector 330 to realize the connection between the frame body and the cradle bend 310. At this time, the left bracket 101 and the right bracket 102 have multiple functions of installing the pedal 200 and connecting with the cradle bend 310, avoiding the need for additional welding of brackets or additional drilling to reserve positions for installation points, making the overall structure reasonable and compact, reducing the space occupied, and making operation simpler.

[0028] Reference Figures 1 to 4 The left and right supports 101 and 102 are both made of cast iron to facilitate their design and multiple functions, offering a simple and convenient solution. Both supports 101 and 102 have mounting holes through which the frame body passes for installation and fixation. Furthermore, the first boss 103 has a mounting groove, and the connecting part 210 extends into the mounting groove and is connected to the first boss 103 via a first fastener. This structure ensures a more stable installation of the pedal 200. Alternatively, the mounting groove can be located on the connecting part 210, in which case the first boss 103 is embedded in the mounting groove and connected to the first boss 103 via a first fastener, thus mounting the pedal 200 onto the left and right supports 101 and 102.

[0029] Optionally, the left bracket 101 is provided with a third protrusion 105, and the third protrusion 105 is provided with a side support 106. Specifically, the side support 106 is provided with a slot, and the third protrusion 105 is embedded in the slot and connected to the side support 106 through a second fastener. By providing the third protrusion 105 on the left bracket 101, the left bracket 101 not only has the multiple functions of installing the foot pedal 200 and connecting to the cradle bend 310, but also has the function of installing the side support 106. Thus, the mounting points of the foot pedal 200, the cradle bend 310, and the side support 106 are all integrated on the left bracket 101, making the structure more reasonable and compact.

[0030] Of course, the slot can also be set on the third protrusion 105. In this case, the side support 106 is embedded in the slot and connected to the left bracket 101 through the second fastener, thereby realizing the installation of the side support 106.

[0031] Optionally, the right bracket 102 is provided with a fourth protrusion 107, which is connected to a shift lever 108. By providing the fourth protrusion 107 on the right bracket 102, the right bracket 102 not only simultaneously has the functions of mounting the foot pedal 200 and connecting to the cradle bend 310, but also has the function of mounting the shift lever 108. This integrates the mounting points of the foot pedal 200, the cradle bend 310, and the shift lever 108 onto the right bracket 102, making the structure more rational and compact. Furthermore, the shift lever 108 is connected to an adjustment component 109, which is provided with a shift cover 110. The right bracket 102 is provided with a fifth protrusion 111, and the shift cover 110 is connected to the fifth protrusion 111. By providing a fifth protrusion 111 on the right bracket 102, the right bracket 102 can simultaneously integrate multiple mounting points for the foot pedal 200, cradle bend 310, shift lever 108, and adjustment assembly 109, further improving the rationality and compactness of the structure.

[0032] Reference Figure 1 and Figure 2 In this embodiment, a hanging pipe 112 is provided between the left support 101 and the right support 102. The hanging pipe 112 is provided with a mounting plate 113, which is used to install the shock absorption components. By providing the hanging pipe 112, the left support 101 and the right support 102 are connected together to form part of the frame, which plays a supporting role and ensures the stability of the frame body. At the same time, the shock absorption components can be installed through the mounting plate 113 on the hanging pipe 112, making the structure reasonable and compact, and easy to manufacture and install.

[0033] Reference Figure 1 and Figure 2 In some embodiments of this application, the main frame includes a headstock tube 114, a main beam tube, and a secondary beam tube 117. The main beam tubes are symmetrically arranged on both sides of the upper end of the headstock tube 114, extending rearward to the rear of the frame. A support tube 118 is provided below the main beam tube, with a left support 101 and a right support 102 respectively disposed on the support tube 118. The secondary beam tubes 117 are symmetrically arranged on both sides of the lower end of the headstock tube 114, and are connected to the cradle bend tube 310. By symmetrically arranging the main beam tubes and secondary beam tubes 117 on both sides, the stability of the main frame can be improved. The main beam tube includes a first tube 115 and a second tube 116. The first tube 115 is connected to the headstock tube 114. The second tube 116 is located behind the first tube 115. A first horizontal tube 119 and a second horizontal tube 120 are respectively connected to the middle of the first tube 115 and the middle of the second tube 116. A support tube 118 is connected to the first tube 115, and a reinforcing tube 121 is provided between the support tube 118 and the second tube 116. Specifically, the first tube 115 is bent downward to form the support tube 118. The second tube 116 is welded and fixed to the bend of the first tube 115, and the reinforcing tube 121 is used to connect the second tube 116 and the support tube 118, thereby making the structure of the main frame more stable. Of course, the structure of the main frame can also adopt a structure commonly used in related technologies, and no restrictions are imposed on this.
