[0017] In one embodiment, there are two connecting beams, namely a first connecting beam and a second connecting beam;

[0018] The bottom of the first connecting beam is integrally provided with the bottom frame, and the other end of the first main beam and the other end of the second main beam are both fixed to the bottom of the first connecting beam;

[0019] The base frame also includes a crossbeam, one end of which is fixed to the first side beam, and the other end of which is fixed to the second side beam; the bottom of the second connecting beam is integrally arranged with the bottom frame, and the setting height of the bottom of the second connecting beam is lower than the setting height of the crossbeam, and the crossbeam and the second connecting beam form an installation position, which is used to install a central motor, and the bottom frame is used to install a power supply.

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0034] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Please refer to Figures 1 to 4 One embodiment provides a vehicle frame, comprising a base frame and a main frame, wherein the main frame is mounted on the base frame.

[0036] like Figure 1 、 Figure 3 and Figure 4 As shown, the base frame includes a bottom frame 110 and an outer frame, the outer frame is fixed to the bottom frame 110, the bottom frame 110 is projected on the ground and forms a first outline, and the outer frame is projected on the ground and forms a second outline, at least a portion of the second outline is located outside the first outline.

[0037] like Figure 1 As shown, the bottom frame 110 may be a roughly rectangular frame structure, for example, a long rectangular frame structure, with the length direction being the front-to-back direction of the motorcycle.

[0038] Optionally, the bottom frame 110 may be an integral structure or may be welded from multiple pipes or beams.

[0039] like Figure 1 、 Figure 3 and Figure 4 The main frame includes a first main beam 210 and a second main beam 220, one end of the first main beam 210 and one end of the second main beam 220 are fixed to the column 400 of the motorcycle, and the other end of the first main beam 210 and the other end of the second main beam 220 are fixed to the bottom frame 110.

[0040] like Figure 1 In the illustrated embodiment, the first main beam 210 and the second main beam 220 form a double main beam structure, and one end of the first main beam 210 and one end of the second main beam 220 are both fixed to the pillar 400 to be connected to the front of the motorcycle.

[0041] It is understandable that the pillar 400 may be a tube structure to cooperate with the front of the vehicle.

[0042] In this frame, the bottom frame 110 is projected on the ground to form a first outline, and the outer frame is projected on the ground to form a second outline, and at least a part of the second outline is located outside the first outline. Therefore, in the horizontal direction, the area where the outer frame is located exceeds the area where the bottom frame 110 is located, which is equivalent to expanding the space in the horizontal direction, thereby reserving more space for arranging pedals without affecting the strength and rigidity of the entire vehicle; and the main frame forms a double-main-beam frame structure through the arrangement of the first main beam 210 and the second main beam 220, which improves the strength and rigidity of the frame compared to the single-main-beam frame.

[0043] In one embodiment, please refer to Figures 1 to 4 One end of the first main beam 210 extends toward a side away from the ground and is fixed to the column 400 , and the other end of the first main beam 210 extends horizontally toward one side of the bottom frame 110 and is fixed to the bottom frame 110 .

[0044] In one embodiment, please refer to Figures 1 to 4 One end of the second main beam 220 extends toward a side away from the ground and is fixed to the column 400 , and the other end of the second main beam 220 extends horizontally toward one side of the bottom frame 110 and is fixed to the bottom frame 110 .

[0045] like Figure 1 and Figure 2 From the perspective shown, one end of the first main beam 210 is bent upward and extends upward until it reaches the position of the column 400, thereby being further fixed to the column 400; while the other end of the first main beam 210 extends horizontally toward one side of the bottom frame 110 until it reaches the position of the bottom frame 110, thereby being further fixed to the bottom frame 110.

[0046] Similarly, if Figure 1 The perspective shown and combined Figure 2 One end of the second main beam 220 is bent upward and extends upward until it reaches the position of the column 400, thereby further being fixed to the column 400; and the other end of the second main beam 220 extends horizontally toward one side of the bottom frame 110 until it reaches the position of the bottom frame 110, thereby further being fixed to the bottom frame 110.

[0047] It is understandable that:

[0048] The length of the other end of the first main beam 210 horizontally extending toward one side of the bottom frame 110 and the length of the other end of the second main beam 220 horizontally extending toward one side of the bottom frame 110 are set based on the actual space arrangement, for example Figure 2In the embodiment shown, the length of the other end of the first main beam 210 extending toward one side of the bottom frame 110 is very short and can be ignored. It can also be roughly regarded as the other end of the first main beam 210 being bent toward one side of the bottom frame 110 and fixed to the bottom frame 110, which will not be repeated.

[0049] In one embodiment, please refer to Figure 1 and Figure 4 There is a gap between the other end of the first main beam 210 and the other end of the second main beam 220, so that a placement area is formed between the first main beam 210 and the second main beam 220.

[0050] like Figure 1 and Figure 4 In the illustrated embodiment, a gap is defined between the other end of the first main beam 210 and the other end of the second main beam 220. This gap is approximately equal to the width of the base frame 110. This arrangement creates a gap between the first and second main beams 210, 220, which serves as a storage area for other electronic components such as motors and heat sinks, resulting in a more compact structure.

[0051] In addition, there is a gap between the other end of the first main beam 210 and the other end of the second main beam 220, so that the overall force of the first main beam 210 and the second main beam 220 is more balanced.

[0052] Optionally, the first main beam 210 and the second main beam 220 are symmetrically arranged on both sides of the column 400 .

[0053] like Figure 1 、 Figure 3 and Figure 4 As shown, one end of the first main beam 210 and one end of the second main beam 220 are both fixed to the column 400, and the fixing position of the first main beam 210 and the column 400 and the fixing position of the second main beam 220 and the column 400 are approximately at the same position.

[0054] It is understandable that:

[0055] like Figure 1 As shown, if the forward direction of the motorcycle is the front, the backward direction of the motorcycle is the rear, the dimension of the bottom frame 110 in the front-to-back direction is the length, and the dimension of the bottom frame 110 in the left-to-right direction is the width.

[0056] In one embodiment, please refer to Figure 1 、 Figure 3 and Figure 4The outer frame includes a first side beam 121 and a second side beam 122 , the first side beam 121 and the second side beam 122 are both fixed to the bottom frame 110 , and the first side beam 121 and the second side beam 122 are respectively located on opposite sides of the bottom frame 110 .

[0057] like Figure 1 As shown, the first side beam 121 and the second side beam 122 are respectively located on opposite sides of the bottom frame 110 in a top view, so as to respectively expand the pedal space on the left and right sides of the motorcycle.

[0058] In one embodiment, please refer to Figure 2 and Figure 3 , the setting height of the first side beam 121 is higher than the setting height of the bottom frame 110; the setting height of the second side beam 122 is higher than the setting height of the bottom frame 110.

[0059] like Figure 2 and Figure 3 As shown, the bottom frame 110 is a substantially horizontally extending frame structure, and the height of the first side beam 121 and the height of the second side beam 122 are both higher than the bottom frame 110 for supporting the pedals.

[0060] Optionally, the first side beam 121 and the second side beam 122 are symmetrically arranged on opposite sides of the bottom frame 110, thereby improving the stability and force balance of the entire frame structure.

[0061] In one embodiment, please refer to Figure 1 and Figure 4 One end of the first side beam 121 is bent toward one side of the second side beam 122 and fixed to the first main beam 210; one end of the second side beam 122 is bent toward one side of the first side beam 121 and fixed to the second main beam 220.

[0062] like Figure 1 In the illustrated embodiment, one end of the first side beam 121 extends toward and is further secured to the side of the first main beam 210. Similarly, one end of the second side beam 122 extends toward and is further secured to the side of the second main beam 220. This arrangement allows the first and second side beams 121, 122 to further expand the width of the chassis, thereby increasing pedal space.

[0063] For example, Figure 1 In the illustrated embodiment, one end of the first side beam 121 and one end of the second side beam 122 are both substantially extended in an arc shape.

[0064] In one embodiment, please refer to Figures 1 to 4The base frame also includes a connecting beam, which is U-shaped. The bottom of the connecting beam is fixed to the bottom frame 110 or the bottom of the connecting beam is integrally formed with the bottom frame 110, and the two ends of the connecting beam are respectively fixed to the first side beam 121 and the second side beam 122.

[0065] like Figure 3 and Figure 4 As shown, the connecting beam is arranged in a roughly U-shaped structure. The bottom of the connecting beam is integrally formed with the bottom frame 110, that is, the bottom of the connecting beam is part of the bottom frame 110, and the two ends of the connecting beam are respectively fixed to the first side beam 121 and the second side beam 122. This arrangement makes the first side beam 121, the second side beam 122 and the bottom frame 110 form a frame structure. For example, the first side beam 121, the second side beam 122, the bottom frame 110 and the connecting beam cooperate to form a cradle frame structure.

[0066] In one embodiment, please refer to Figures 1 to 4 There are two connecting beams, namely a first connecting beam 131 and a second connecting beam 132.

[0067] like Figures 1 to 4 As shown, the bottom of the first connecting beam 131 is integrally provided with the bottom frame 110 , and the other end of the first main beam 210 and the other end of the second main beam 220 are both fixed to the bottom of the first connecting beam 131 .

[0068] like Figure 1 and combined Figure 2 As shown, the bottom of the first connecting beam 131 is part of the bottom frame 110. The lower ends of the first main beam 210 and the second main beam 220 are both fixed to the bottom of the first connecting beam 131, and there is a gap between the lower ends of the first main beam 210 and the second main beam 220. The two ends of the first connecting beam 131 are respectively fixed to the first side beam 121 and the second side beam 122.

[0069] like Figure 3 and combined Figure 2 As shown, the base frame also includes a crossbeam 140, one end of the crossbeam 140 is fixed to the first side beam 121, and the other end of the crossbeam 140 is fixed to the second side beam 122; the bottom of the second connecting beam 132 is integrally arranged with the bottom frame 110, and the setting height of the bottom of the second connecting beam 132 is lower than the setting height of the crossbeam 140, and the crossbeam 140 and the second connecting beam 132 form an installation position, which is used to install the central motor 500, and the bottom frame 110 is used to install the power supply.

[0070] like Figure 3As shown, the chassis is also provided with a crossbeam 140, which extends in the left-right direction of the motorcycle and is positioned generally horizontally. The bottom of the second connecting beam 132 is part of the bottom frame 110, and the two ends of the second connecting beam 132 are respectively fixed to the first side beam 121 and the second side beam 122. The second connecting beam 132 is located on the lower side of the crossbeam 140, and the second connecting beam 132 and the crossbeam 140 form a mounting position for mounting the mid-mounted motor 500. The bottom frame 110 is used to mount a power supply, such as a replaceable battery.

[0071] Optionally, the first main beam 210, the second main beam 220, the bottom frame 110, the first side beam 121, the second side beam 122, the first connecting beam 131, the second connecting beam 132 and the cross beam 140 can all be tubular structures and fixed by welding to form a cradle frame structure, which not only reduces the weight of the frame, but also simplifies the manufacturing process and reduces production costs.

[0072] In one embodiment, please refer to Figure 3 and Figure 4 The frame further includes a rear cradle 300 , which is movably connected to the second connecting beam 132 . The rear cradle 300 is located on a side of the second connecting beam 132 away from the first connecting beam 131 .

[0073] like Figure 3 and Figure 4 As shown, a rear cradle 300 is provided on the rear side of the frame. The rear cradle 300 is rotatably provided on the second connecting beam 132. The rear cradle 300 is used to mount the rear wheel of the motorcycle.

[0074] In one embodiment, please refer to Figure 3 and Figure 4 The other end of the first side beam 121 and the other end of the second side beam 122 are both inclined and extended toward a side away from the ground, and the setting height of the other end of the first side beam 121 and the setting height of the other end of the second side beam 122 are both higher than the setting height of the rear cradle 300.

[0075] like Figure 3 and Figure 4 As shown, the other end of the first side beam 121 and the other end of the second side beam 122 are both bent and extended upward, and the bent and extended portion is not lower than the height of the rear cradle 300 .

[0076] Another embodiment provides a motorcycle comprising the frame according to any one of the above embodiments.

The bottom frame 110 is projected on the ground to form a first outline, and the outer frame is projected on the ground to form a second outline, and at least a part of the second outline is located outside the first outline. Therefore, in the horizontal direction, the area where the outer frame is located exceeds the area where the bottom frame 110 is located, which is equivalent to expanding the space in the horizontal direction, thereby reserving more space for arranging the pedals without affecting the strength and rigidity of the entire vehicle; and the main frame forms a double-main-beam frame structure through the arrangement of the first main beam 210 and the second main beam 220, which improves the strength and rigidity of the frame compared to the single-main-beam frame.
