[0029] The present application provides a motorcycle frame with multiple seat heights, and also provides a motorcycle 100 comprising the motorcycle frame with multiple seat heights of the present application. In some embodiments, the motorcycle 100 further comprises a driving motor 60 and a power battery 70, the driving motor 60 drives the wheels, and the power battery 70 provides electric energy for the driving motor 60. In other embodiments, the motorcycle 100 comprises an engine. Figures 1-2 The motorcycle 100 of one embodiment of the present application is illustrated, Figures 3-4The motorcycle frame with multiple sitting heights is shown in an embodiment of the utility model.

[0030] The motorcycle frame with multiple sitting heights (for the convenience of description, hereinafter referred to as the motorcycle frame) is compatible with the installation of the driving motor 60 and the power battery 70, and is compatible with multiple sitting height, so that the motorcycle 100 of the utility model has the sitting height adjustment function, and the sitting height adjustment function changes the height of the cushion to adapt the motorcycle 100 to consumers with different body sizes.

[0031] Referring to Figures 1-4 Meanwhile, please refer to Figures 5-6 The motorcycle frame comprises a front pipe 10, a cage, two groups of motor seats 30, a suspension piece 40, a side limiting piece 50 and a cushion support platform, the front pipe 10 is provided for the front fork of the motorcycle 100 to pass through and allows the front fork to rotate in the front pipe 10, the cage is fixedly connected with the front pipe 10 as a whole, the cage comprises two groups of frames 20 connected to the outer side walls of the front pipe 10, each group of frames 20 comprises a bearing frame 21, further comprises a bottom beam 221 and a lower beam 222, the bearing frame 21 comprises an upper beam 211 and a rear beam 212, both ends of the upper beam 211 are connected with the front pipe 10 and the top end of the rear beam 212 respectively, the bottom beam 221 and the lower beam 222 are located on the side of the upper beam 211 relatively close to the ground, the bottom end of the rear beam 212 is connected with the rear end of the bottom beam 221, both ends of the lower beam 222 are connected with the front pipe 10 and the front end of the bottom beam 221 respectively. The top end and the bottom end of the rear beam 212 are the end relatively far away from the ground and the end relatively close to the ground of the rear beam 212 respectively, the two bottom beams 221 form the bottom side of the motorcycle frame closest to the ground, the cushion support platform is located on the side of the cage relatively far away from the ground, and is provided with a cushion.

[0032] Referring to Figures 3-4The cage is configured to form a motor mounting space 201 and a battery placement space 202 located at the rear of the front pipe 10, the rear of the front pipe 10 refers to the area of the front pipe 10 relatively close to the side of the rear wheel of the motorcycle 100 and lower than the front pipe 10 in the vertical direction, the battery placement space 202 is located between the front pipe 10 and the motor mounting space 201. The motor mounting space 201 has a motor opening opening to the ground, and the motor opening is specifically located between the two bottom beams 221. The battery placement space 202 has a battery opening opening upward away from the ground, and the battery opening is specifically located between the two upper beams 211. The two groups of motor seats 30 are respectively front hangers 31 and rear hangers 32. The front hangers 31 include two front seat bodies 311, and the two front seat bodies 311 are respectively fixedly connected to the two lower beams 222. The rear hangers 32 include two rear seat bodies 321, and the two rear seat bodies 321 are respectively fixedly connected to the two rear beams 212. The front hangers 31 and the rear hangers 32 are spaced apart and opposite along the length direction of the motor opening, the length direction of the motor opening is the length direction of the bottom beam 221, and is perpendicular to the rear wheel axis direction of the motorcycle 100. When the motorcycle 100 travels in a straight line on a horizontal road surface, the length direction of the bottom beam 221 can be a horizontal straight line direction.

[0033] Referring to Figures 5-6 The driving motor 60 includes a cylindrical shell and two hangers, the two hangers are respectively front hangers 611 and rear hangers 612, the front hangers 611 and the rear hangers 612 are respectively protruded on two opposite half sides of the shell, each half side is a half circumferential side of the shell, the two half sides do not overlap and together constitute the entire circumferential side of the shell. The front hangers 611 and the front hangers 31 are detachably connected through threaded connectors or quick plug-in connectors, and the rear hangers 612 and the rear hangers 32 are detachably connected through threaded connectors or quick plug-in connectors. As preferred, the front hangers 31 and the rear hangers 32 are both provided with pin holes 33, the axis of the pin holes 33 extends in the horizontal direction and is perpendicular to the two bottom beams 221, the pin holes 33 allow the bolts or quick plug-in pins to pass through and extend into the front hangers 611 and the rear hangers 612. When the quick plug-in pins pass through the pin holes 33 and extend into the front hangers 611 and the rear hangers 612, a locking mechanism can also be provided to lock the quick plug-in pins, thereby limiting the axial freedom degree of the quick plug-in pins to prevent the quick plug-in pins from falling off.

[0034] The motor passageway allows the driving motor 60 to pass through during disassembly and assembly, so that the driving motor 60 enters or exits the motor installation space 201. After the front lifting lug 611 and the front lifting seat 31 are separated and the rear lifting lug 612 and the rear lifting seat 32 are separated, the driving motor 60 can be lifted and lowered to pass through the motor passageway and exit the motor installation space 201. The driving motor 60 can be removed by lowering, which can save the time for removing the driving motor 60, reduce the moving height of the driving motor 60 to the ground, and facilitate users and maintenance personnel to quickly complete the disassembly and assembly of the driving motor 60. The two spaced-apart motor seats 30 can ensure the rationality of the stress of the driving motor 60 after installation, and effectively and consistently drive the driving motor 60 to shake and vibrate. Optionally, the front lifting lug 611 and the rear lifting lug 612 are symmetrically arranged on the two opposite sides of the driving motor 60, and the front lifting lug 611, the rear lifting lug 612, and the output shaft of the driving motor 60 are approximately at the same vertical height. In this way, the front lifting lug 611 and the rear lifting lug 612 apply symmetric forces to the driving motor 60 through the front lifting seat 31 and the rear lifting seat 32, respectively. Therefore, the front lifting seat 31 and the rear lifting seat 32 can equally share external forces, reducing the risk of deformation or overload of the motor seat 30.

[0035] Referring to Figures 1-2 、 Figures 5-6 The power battery 70 is provided with a handle at the bottom, and a user can hold the handle and drive the power battery 70 to pass through the battery passageway, so as to take out or put the power battery 70 into the battery installation space 202. The suspension support 40 and the cage are formed in a split structure and are fixedly installed, and the side limiting piece 50 and the cage are formed in a split structure and are fixedly installed. The side of the suspension support 40 away from the ground faces the battery passageway. The side limiting piece 50 is located behind the front pipe 10, and the front pipe 10 and the side limiting piece 50 are both inclined backward. An acute angle α is formed between the axis of the front pipe 10 and the horizontal plane, and an acute angle β is formed between the side limiting piece 50 and the horizontal plane. The side limiting piece 50 is opposite to the front pipe 10 and relatively close to the rear wheel of the motorcycle 100. The angle α can be equal to or different from the angle β.

[0036] When the power battery 70 is placed in position in the battery placement space 202, the suspension support 40 acts on the bottom of the power battery 70, and the side limiting member 50 acts on the side of the power battery 70 facing away from the front pipe 10, and the suspension support 40 and the side limiting member 50 cooperate to limit the freedom of movement of the power battery 70, so as to avoid the power battery 70 from shaking during driving the motorcycle 100; when the user holds the handle and drives the power battery 70 through the battery pass, the side limiting member 50 can act on the side of the power battery 70 in a sliding contact manner, and guide the power battery 70 to move into or out of the battery placement space 202 along the inclined direction of the side limiting member 50. The inclined direction of the side limiting member 50 enables the side limiting member 50 to apply a supporting force to the side of the power battery 70, so as to reduce the carrying force applied by the user to the handle, and make the user more relaxed and labor-saving when taking and placing the power battery 70. In addition, the guiding action of the side limiting member 50 on the power battery 70 can protect the power battery 70 from being tilted and colliding with the cage or scratching the frame 20, and can protect the power battery 70.

[0037] In some embodiments, the cage includes a plurality of BIK500 steel pipes that jointly form the motor mounting space 201 and the battery placement space 202. Optionally, the frame 20 is formed by welding a plurality of BIK500 steel pipes, for example, the upper beam 211, the rear beam 212, the bottom beam 221 and the lower beam 222 can all be made of BIK500 steel pipes. In this way, the structural strength and durability of the cage can be ensured while reducing the weight of the cage, thereby achieving the light weight of the motorcycle frame.

[0038] Referring to Figures 2-6 The upper beam 211 protrudes from the side of the front pipe 10 and extends rearward of the front pipe 10. The extension state of the upper beam 211 is that the height of the upper beam 211 from the ground decreases in a direction away from the front pipe 10. The upper beam 211 is provided with a load-bearing seat 23, which includes a plurality of groups of mounting portions. Each group of mounting portions defines an installation position as a whole unit, and forms a detachable connection with the cushion support platform. The heights of the plurality of installation positions from the ground decrease in an extension direction of the load-bearing frame 21, which includes the extension direction of the upper beam 211. The upper beam 211 extends away from the front pipe 10 and gradually approaches the ground. When the cushion support platform is connected with any one group of mounting portions, the position of the cushion support platform at this time is the installation position of this group of mounting portions. Therefore, the motorcycle frame provides a plurality of installation positions corresponding to different sitting heights by providing a plurality of groups of mounting portions, so that the motorcycle frame can provide a plurality of sitting heights. By switching the mounting portion connected with the cushion support platform, the cushion support platform can be transferred from the installation position defined by the mounting portion before disassembly to a new installation position, and the height of the cushion on the cushion support platform also changes accordingly. Figure 1 and Figure 9 The motorcycle 100 is shown in two different sitting heights, respectively, and Figure 1Compared with Figure 9 The motorcycle 100 shown is raised in the sitting position.

[0039] Optionally, the motor mounting space 201 is entirely located within the envelope space of the cage, so that the drive motor 60 is entirely located within the envelope space of the cage. Preferably, referring to Figure 9 In some embodiments, the motorcycle frame further comprises a frame cover 90 which is detachably arranged on the hollow hole of the cage to close the motor mounting space 201, the frame cover 90 improves the aesthetics of the motorcycle 100 and can protect the drive motor 60. When the drive motor 60 needs to be disassembled, the frame cover 90 can be removed from the cage first, then the disassembly tool is inserted into the motor mounting space 201 through the hollow hole, and force is applied to the connecting member connecting the motor seat 30 and the lifting lug. After the drive motor 60 is reinstalled into the motor mounting space 201, the frame cover 90 is re-arranged on the hollow hole of the cage. The drive motor 60 entirely located within the envelope space of the cage does not interfere with the frame cover 90.

[0040] Referring to Figures 3-6 In some embodiments, the cage further comprises a support member 24, a reinforcing column 25 and a reinforcing beam 26 arranged between the two groups of frames 20. Specifically, the two ends of the support member 24 are respectively connected to the two rear beams 212, or the two ends of the support member 24 can also be respectively connected to the two bottom beams 221. The two ends of the reinforcing column 25 are respectively connected to the two upper beams 211, or the two ends of the reinforcing column 25 can also be respectively connected to the two rear beams 212. The two ends of the reinforcing beam 26 are respectively connected to the two lower beams 222. In this way, the distance between the two groups of frames 20 is fixed, and the rigidity and strength of the entire cage are significantly improved. The support member 24, the reinforcing column 25 and the reinforcing beam 26 can be BIK500 steel pipes. The support member 24 and the reinforcing column 25 can be two columnar structures extending in the horizontal straight line direction, and the length direction of the two can be perpendicular to the length direction of the bottom beam 221. The length direction of the support member 24 and the reinforcing column 25 can be the width direction of the motor pass-through and the width direction of the battery pass-through. The two groups of frames 20 are therefore arranged at intervals along the width direction of the motor pass-through. The two front seat bodies 311 are arranged at intervals along the width direction of the motor pass-through, and the two rear seat bodies 321 are arranged at intervals along the width direction of the motor pass-through.

[0041] The support 24 defines a motor passing opening formed on the side of the support 24 facing away from the rear wheel of the motorcycle 100, and the support 24 can also be used to temporarily support the drive motor 60. When the front hanger 31 and the rear hanger 32 are connected to the front hanger lug 611 and the rear hanger lug 612 of the drive motor 60 respectively, the support 24 and the drive motor 60 are spaced apart and do not contact each other. When the front hanger 31 and the front hanger lug 611 are separated, the drive motor 60 can rotate around the center line of the rear hanger 32 in the motor mounting space 201 until the drive motor 60 abuts against the support 24, and the center line of the rear hanger 32 is the axis of the pin hole 33 formed in the rear hanger 32. In this embodiment, it is specified that when the drive motor 60 and the motorcycle frame are disassembled, the front hanger 31 and the front hanger lug 611 are disassembled first, then the drive motor 60 is rotated around the center line of the rear hanger 32, and the transmission member connected to the output shaft of the drive motor 60, such as a transmission sprocket, can rotate with the drive motor 60. At this time, the transmission chain wound around the transmission sprocket changes from being tensioned to being relaxed, the support 24 temporarily supports the drive motor 60, and the user can continue to disassemble the rear hanger 32 and the rear hanger lug 612 without manually lifting the drive motor 60 to apply force to the disassembly tool.

[0042] Again refer to Figures 1-3 , Figures 5-6 The distance between the two front seat bodies 311 connected to the two lower beams 222 is d1, and the distance between the two rear seat bodies 321 connected to the two rear beams 212 is d2, d1 The motorcycle 100 also includes a wheel swing arm 80 on which the rear wheel is mounted, and the rear end of the wheel swing arm 80 is provided with a wheel bearing for connecting the rear wheel. The two front ends of the wheel swing arm 80 extend into the space between the two rear hangers 32, and the two ends of the rear hanger lug 612 of the drive motor 60 are respectively provided with the two front ends of the wheel swing arm 80. At this time, the rear hanger lug 612 and the two front ends of the wheel swing arm 80 located at the two ends of the rear hanger lug 612 are both located in the accommodation gap and are penetrated by the same pin shaft, and the two ends of the pin shaft extend into the pin holes 33 of the two rear hangers 32. In this way, the wheel swing arm 80 can rotate around the center line of the rear hanger 32, and the total width of the ends of the wheel swing arm 80 located in the accommodation gap is Δd, which is the sum of the widths of the two front ends of the wheel swing arm 80. In this way, the rotation connection of the wheel swing arm 80 to the cage and the installation of the drive motor 60 are simultaneously achieved by one pin shaft, which simplifies the structure of the motorcycle frame and the motorcycle 100 and reduces the production cost of the motorcycle frame.

[0043] Further, refer to Figures 3-4The front hanger 31 further comprises a seat bracket 312, one end of the seat bracket 312 is fixedly connected to the front seat body 311, and the other end of the seat bracket 312 forms a connecting pipe edge, the connecting pipe edge is fixedly connected to the outer side wall of the lower beam 222, the seat bracket 312 extends into the motor mounting space 201 relative to the lower beam 222, and the two seat brackets 312 connected to the two lower beams 222 are close to each other, so that the two front seat bodies 311 connected to the two seat brackets 312 form a spacing with a size of d1. Alternatively, the seat bracket 312 and the front seat body 311 are an integral molding structure, and the seat bracket 312 is welded and fixed to the lower beam 222. The width of the seat bracket 312 changes in a trend of increasing from one end of the seat bracket 312 connected to the front seat body 311 to the connecting pipe edge. In this way, when the front lug 611 of the driving motor 60 is connected to the front seat body 311, the force of the driving motor 60 acting on the lower beam 222 through the front hanger 31 is distributed at the connection between the lower beam 222 and the connecting pipe edge, and the increased length of the connecting pipe edge is conducive to dispersing the reaction force on the lower beam 222, thereby reducing the stress at the connection between the lower beam 222 and the connecting pipe edge and ensuring reliable connection of the front hanger 31.

[0044] Further, referring to Figures 3-6 The rear beam 212 and the rear hanger 32 are a split molding structure, the rear beam 212 is provided with an embedded seat groove, the embedded seat groove allows the rear hanger 32 to be fixedly arranged therein, and the rear hanger 32 and the inner wall of the embedded seat groove can form a fixed fit to realize fixed connection of the rear hanger 32 and the rear beam 212, or the rear hanger 32 and the inner wall of the embedded seat groove can be welded and fixed. The structure of the rear hanger 32 is relatively complex, and the split molding of the rear beam 212 and the rear hanger 32 can reduce the molding difficulty of the motorcycle frame and the cost of the production process.

[0045] Referring to Figures 1-2 , Figures 5-6 Also referring to Figures 7-8The suspension support 40 is mounted on the reinforcing beam 26 by fasteners and comprises a suspension plate 41, which is arranged obliquely and the side of the suspension plate 41 facing away from the ground is directed towards the battery pass-through. The side limiting member 50 comprises a partition plate 52 fixedly connected to the reinforcing column 25, the partition plate 52 is arranged obliquely backward and forms an acute angle β with the horizontal plane, the rear of the partition plate 52 is the rear of the side limiting member 50, specifically, the side of the partition plate 52 facing away from the front pipe 10 and close to the rear wheel of the motorcycle 100, the angle α can be equal to or different from the angle β. The suspension plate 41, the partition plate 52 and the cover arranged on the cage together form a battery placement space 202, which corresponds to the angle space between the suspension plate 41 and the partition plate 52, i.e. the angle space between the suspension support 40 and the side limiting member 50, and the angle opening between the suspension plate 41 and the partition plate 52 is arranged to face away from the ground. When the power battery 70 is placed in the battery placement space 202, the suspension plate 41 contacts the bottom of the power battery 70, and the partition plate 52 contacts the side of the power battery 70 facing away from the front pipe 10. The power battery 70 is reacted on the reinforcing column 25 through the partition plate 52, so that the reinforcing column 25 indirectly supports the side of the power battery 70 facing away from the front pipe 10. The side of the partition plate 52 facing away from the battery placement space 202 and the front pipe 10 is a motor installation space 201. When the user applies a carrying force to the handle of the power battery 70, the partition plate 52 slides and contacts the power battery 70 and guides the power battery 70 to pass through the battery pass-through along the oblique direction of the partition plate 52.

[0046] Specifically, the side limiting member 50 comprises a ground-close end extending towards the suspension support 40 and a ground-far end extending towards the battery pass-through, the suspension plate 41 comprises a front support end 411 away from the ground-close end of the side limiting member 50 and a rear support end 412 close to the ground-close end of the side limiting member 50, the ground clearance of the suspension support 40 is the distance from the suspension plate 41 to the ground, and the ground clearance of the suspension support 40 gradually decreases from the front support end 411 to the rear support end 412. Optionally, the two upper beams 211 are parallel to the suspension plate 41, so that the suspension plate 41 is parallel to the battery pass-through, and the extension direction of the partition plate 52 is approximately perpendicular to the suspension plate 41, so that the side limiting member 50 guides the power battery 70 to move into and out of the battery placement space 202 along the vertical direction of the suspension plate 41. When the power battery 70 is kept in contact with the partition plate 52 and slides along the partition plate 52 to the lowest position, the bottom of the power battery 70 directly contacts the side of the suspension plate 41 facing away from the ground.

[0047] Referring to Figures 7-8In some embodiments, the side limiting member 50 further comprises a special-shaped portion 51, the partition plate 52 extends to the suspension support 40 as the ground proximal end of the side limiting member 50, the special-shaped portion 51 is fixedly connected to the ground distal end of the partition plate 52, and the special-shaped portion 51 extends to the battery passageway as the ground distal end of the side limiting member 50, the reinforcing column 25 is adapted to the special-shaped portion 51 and forms a detachable connection. Optionally, the special-shaped portion 51 is a curled structure and is integrally formed with the partition plate 52, the special-shaped portion 51 is configured to form an arc-shaped slot 511 opening downward, the inner wall of the arc-shaped slot 511 is adapted to the outer side wall of the reinforcing column 25, and the special-shaped portion 51 is detachably hooked to the reinforcing column 25 through the arc-shaped slot 511. In this way, the side limiting member 50 can be detached from the cage for maintenance and repair of the motorcycle 100, and the installation of the side limiting member 50 and the cage is simpler, that is, the reinforcing column 25 can be pressed into the arc-shaped slot 511 by applying pressure to the special-shaped portion 51; when the side limiting member 50 and the cage are detached, a lifting force in a direction away from the suspension support 40 is applied to the special-shaped portion 51 to make the reinforcing column 25 exit the arc-shaped slot 511. The side limiting member 50 and the cage are formed in a split structure, which can reduce the forming difficulty and production cost of the motorcycle frame.

[0048] It can be understood that, in other embodiments, a clamping slot can also be formed on the reinforcing column 25, the special-shaped portion 51 is detachably inserted into the clamping slot, and the special-shaped portion 51 and the reinforcing column 25 can be detached by applying a lifting force to the special-shaped portion 51 away from the suspension support 40 and pulling the special-shaped portion 51 out of the clamping slot when the side limiting member 50 is detached; when the side limiting member 50 is installed to the cage, a downward pressure is applied to the special-shaped portion 51 to make the special-shaped portion 51 inserted into the clamping slot.

[0049] Further, referring to Figures 5-8 , the suspension support 40 further comprises a limiting stop edge 42 and a flared edge 43, the limiting stop edge 42 is bendedly connected to the edge of the suspension plate 41 and extends to the battery passageway, the suspension plate 41 and the limiting stop edge 42 jointly form a limiting concave cavity, at least a part of the power battery 70 including the bottom of the power battery 70 is located in the limiting concave cavity after the power battery 70 is placed in position in the battery placement space 202, the limiting stop edge 42 limits the power battery 70 from shaking and wobbling by stopping the outer circumferential side of the power battery 70, and the limiting stop edge 42 is perpendicular to the suspension plate 41, so that the space occupied by the limiting concave cavity is approximately a cuboid, which can adapt to the power battery 70 configured in a cuboid, the flared edge 43 is bendedly connected to the edge of the limiting stop edge 42 away from the suspension plate 41 and is inclined to the outside of the limiting stop edge 42 in a direction away from the opening of the limiting concave cavity, and the edge of the flared edge 43 away from the limiting stop edge 42 jointly forms a flared portion, so that the power battery 70 enters the limiting concave cavity under the guidance of the flared edge 43.

[0050] Further, referring to Figures 7-8The at least part of the side limiting member 50 including the end of the partition plate 52 far away from the special-shaped part 51 extends into the limiting concave cavity, the limiting stop edge 42 is further provided with a hooking plate groove 421 communicating with the limiting concave cavity, the part of the side limiting member 50 located in the limiting concave cavity extends into the hooking plate groove 421 and hooks the limiting stop edge 42, the side limiting member 50 located in the limiting concave cavity can be clamped and fixed by the side of the power battery 70 and the limiting stop edge 42, so that the power battery 70, the suspension support 40 and the side limiting member 50 form a compact and stable whole in the cage. Alternatively, the end of the partition plate 52 far away from the special-shaped part 51 is formed with a curled hooking edge, the curled hooking edge extends into the hooking plate groove 421 and hooks the limiting stop edge 42. In this way, the side limiting member 50 and the suspension support 40 are detachably hooked, the arrangement of the hooking plate groove 421 simplifies the structure of the side limiting member 50 and facilitates molding, and the side limiting member 50 and the suspension support 40 are easier to disassemble and assemble.

[0051] Further, referring to Figures 5-6 The distance from the side of the side limiting member 50 opposite to the front pipe 10 and the battery placement space 202 to the rear beam 212 increases in the direction close to the bottom beam 221 and the motor pass-through, in this way, the size of the motor installation space 201 in the length direction of the motor pass-through increases in the direction close to the ground, the driving motor 60 located in the motor installation space 201 can be arranged closer to the motor pass-through and the ground, thereby being beneficial to reduce the overall center of gravity height of the motorcycle 100 and improve the driving control performance of the motorcycle 100, in addition, the required motor installation space 201 of the driving motor 60 and the required battery placement space 202 of the power battery 70 are both smaller, the arrangement of the driving motor 60 and the power battery 70 in the motorcycle frame is more compact, so that the envelope space of the motorcycle frame is reduced, and the efficient use of the internal space of the motorcycle frame is realized.

[0052] When the user applies a carrying force to the handle on the top of the power battery 70, and the direction of the carrying force is away from the ground and parallel to the partition plate 52, the power battery 70 can be taken out of the battery placement space 202. During the power battery 70 passing through the battery pass, the partition plate 52 is in sliding contact to guide the movement of the power battery 70. The reinforcing column 25 indirectly supports the rear side of the power battery 70 to make up for the insufficient rigidity of the partition plate 52. The force of the reinforcing column 25 indirectly acting on the power battery 70 through the special-shaped part 51 includes a vertical upward support vector, which can offset a part of the gravity of the power battery 70, so that the user can take and place the power battery 70 more easily and labor-savingly. The entire battery placement space 202 is approximately an inclined passageway, and the inclination direction of the side limiting part 50 is the inclination direction of the passageway. Therefore, the moving stroke of the power battery 70 in the vertical direction when the power battery 70 is completely removed from the battery placement space 202 can be shortened. The smaller the acute angle β between the side limiting part 50 and the horizontal plane, the shorter the moving stroke of the power battery 70 in the vertical direction during the process of removing the power battery 70 from the battery placement space 202, and the more labor-saving and easy it is to take and place the power battery 70.

[0053] Referring to Figures 3-4 , the load-bearing seat 23 at least includes a first mounting part 2311, a second mounting part 2312, a third mounting part 2321, and a fourth mounting part 2322 arranged in sequence along the extension direction of the load-bearing frame 21. The load-bearing frame 21 includes an upper beam 211 and a rear beam 212. The extension direction of the load-bearing frame 21 includes the direction in which the upper beam 211 extends obliquely rearward of the front pipe 10 to be away from the front pipe 10. Optionally, the first mounting part 2311, the second mounting part 2312, the third mounting part 2321, and the fourth mounting part 2322 are arranged gradually away from the front pipe 10. The first mounting part 2311 and the third mounting part 2321 form a group and define a first mounting position. The second mounting part 2312 and the fourth mounting part 2322 form another group and define a second mounting position. When the cushion support platform is in the second mounting position, it is farther away from the front pipe 10 and closer to the ground than when it is in the first mounting position. Therefore, the cushion height can be lowered by shifting the cushion support platform from the first mounting position to the second mounting position, and vice versa. Figure 1 The motorcycle 100 shown corresponds to the cushion support platform being in the first mounting position, Figure 9 The motorcycle 100 shown corresponds to the cushion support platform being in the second mounting position.

[0054] Further, referring to Figures 1-2 , Figures 5-6The cushion support platform comprises a front protective shell 27 and a cushion support 28 fixedly connected, the front protective shell 27 is located above the two load-bearing frames 21 to cover the battery pass, and extends to the two sides of the two groups of frames 20 away from each other to cover the power battery 70, the cushion support 28 comprises a first load-bearing pipe 281 and a second load-bearing pipe 282 fixedly connected, and the front protective shell 27 and the cushion support 28 jointly bear the cushion; the load-bearing seat 23 further comprises a fifth mounting portion 2323 and a sixth mounting portion 2324, the first mounting portion 2311, the second mounting portion 2312, the third mounting portion 2321, the fourth mounting portion 2322, the fifth mounting portion 2323 and the sixth mounting portion 2324 are arranged gradually away from the front pipe 10 along the extension direction of the upper beam 211. The first mounting portion 2311, the third mounting portion 2321 and the fifth mounting portion 2323 constitute a group and jointly define a first mounting position, and the second mounting portion 2312, the fourth mounting portion 2322 and the sixth mounting portion 2324 constitute another group and jointly define a second mounting position. The first mounting portion 2311 and the second mounting portion 2312 are detachably connected to the front protective shell 27, and the third mounting portion 2321, the fourth mounting portion 2322, the fifth mounting portion 2323 and the sixth mounting portion 2324 are detachably connected to the cushion support 28.

[0055] Specifically, the load-bearing seat 23 comprises a front load-bearing seat 231 and a rear load-bearing seat 232 arranged away from the front pipe 10 in sequence, the distance from the front load-bearing seat 231 to the front pipe 10 is less than the distance from the rear load-bearing seat 232 to the front pipe 10 in the horizontal direction, the front load-bearing seat 231 comprises the first mounting portion 2311 and the second mounting portion 2312, and the rear load-bearing seat 232 comprises the third mounting portion 2321, the fourth mounting portion 2322, the fifth mounting portion 2323 and the sixth mounting portion 2324. When the cushion support platform is in the first mounting position, the front protective shell 27 is connected to the first mounting portion 2311, and the first load-bearing pipe 281 and the second load-bearing pipe 282 are connected to the third mounting portion 2321 and the fifth mounting portion 2323 respectively; when the cushion support platform is in the second mounting position, the front protective shell 27 is connected to the second mounting portion 2312, and the first load-bearing pipe 281 and the second load-bearing pipe 282 are connected to the fourth mounting portion 2322 and the sixth mounting portion 2324 respectively. In Figures 1-9 In the illustrated embodiment, the cushion support platform translates along the extension direction of the upper beam 211 to transfer between different mounting positions, and the angle of the cushion does not change with the change of height. In order to adapt to the transfer of the cushion support platform between different mounting positions in a translational manner, the distance between the first mounting portion 2311 and the second mounting portion 2312 is equal to the distance between the third mounting portion 2321 and the fourth mounting portion 2322, and also equal to the distance between the fifth mounting portion 2323 and the sixth mounting portion 2324, and the distance between the first mounting portion 2311 and the second mounting portion 2312 is actually the translation distance of the cushion support platform from the first mounting position to the second mounting position.

[0056] Further, the detachable connection between the cushion support and the plurality of mounting portions includes: detachable connection through a threaded connecting piece, detachable connection through a quick plug-in connecting piece, plug-in connection, etc. When the cushion support and the plurality of mounting portions are connected by the threaded connecting piece, a dismounting tool is needed to apply force to the threaded connecting piece. When the quick plug-in connecting piece or the plug-in connection is used, no dismounting tool is needed, and the user can manually complete the dismounting and reconnection between the cushion support and the plurality of mounting portions. Referring to Figures 3-4 The first mounting portion 2311, the second mounting portion 2312, the third mounting portion 2321, the fourth mounting portion 2322, the fifth mounting portion 2323, and the sixth mounting portion 2324 are each provided with a mounting hole through which the threaded connecting piece or the quick plug-in connecting piece can pass.

[0057] It can be understood that the number of mounting positions is not limited to two, and more mounting portions can be provided, and the mounting portions define more mounting positions, as long as the plurality of mounting portions defining different mounting positions are arranged in sequence along the extension direction of the load-bearing frame 21, so that the height of the plurality of mounting positions is set to be different along the extension direction of the load-bearing frame 21, and the height of the mounting positions decreases in the direction away from the front pipe 10; the first load-bearing pipe 281 and the second load-bearing pipe 282 can be combined into one load-bearing pipe, and accordingly, the fifth mounting portion 2323 and the sixth mounting portion 2324 can be omitted, and the third mounting portion 2321 and the fourth mounting portion 2322 can be detachably connected to the load-bearing pipe.

[0058] Alternatively, in some embodiments, the front protective shell 27 and the cushion support 28 are provided separately and are detachably connected. In this way, the user can dismount the motorcycle 100 more conveniently, improving the convenience of use. For example, when the power battery 70 needs to be removed, the cushion is first removed from the cushion support, and then the front protective shell 27 only needs to be removed from the load-bearing frame 21 to open the battery passage, and then the handlebar is held to pull the power battery 70 obliquely upward. During the process of removing and placing the power battery 70, the cushion support 28 is always connected to the load-bearing frame 21, and does not need to be removed from the load-bearing frame 21, and the front protective shell 27 is easier to dismount separately.

[0059] In some embodiments not shown in the drawings, the load-bearing seat 23 comprises a front load-bearing seat 231 and a rear load-bearing seat 232 arranged in sequence away from the front pipe 10, the front load-bearing seat 231 is closer to the front pipe 10 than the rear load-bearing seat 232 in the horizontal direction, the front load-bearing seat 231 comprises a first mounting portion 2311, the rear load-bearing seat 232 comprises a second mounting portion 2312 and a third mounting portion 2321 arranged in sequence in the extension direction of the load-bearing frame 21, the extension direction of the load-bearing frame 21 comprises the extension direction of the rear beam 212, optionally, the second mounting portion 2312 and the third mounting portion 2321 are arranged in sequence along the extension direction of the rear beam 212, the second mounting portion 2312 and the third mounting portion 2321 are mutually obtained by rotating the first mounting portion 2311 as the rotation center by a preset angle, the first mounting portion 2311 and the second mounting portion 2312 form a first mounting position, and the first mounting portion 2311 and the third mounting portion 2321 form a second mounting position. In this way, when the cushion support shifts between the first mounting position and the second mounting position, the cushion support substantially rotates around the first mounting portion 2311 as the rotation center. Compared with the way of changing the sitting height by translating the cushion support, the motorcycle frame and the motorcycle 100 of the embodiment can change the height and the pitch angle of the cushion support at the same time, thereby providing a better experience of changing the sitting position for the user. The plurality of mounting portions can be arranged on the upper beam 211, or arranged on the rear beam 212, or arranged on the upper beam 211 and the rear beam 212.

[0060] Optionally, the load-bearing frame 21 and the load-bearing seat 23 are a split molding structure, the surrounding cage including the front pipe 10, the load-bearing frame 21, the lower beam 222, the bottom beam 221, the support 24, the reinforcing column 25, and the reinforcing beam 26 is made of a plurality of BIK500 steel pipes, the load-bearing frame 21 directly bears the reaction force of the cushion support, so the load-bearing frame 21 is made of a material with higher strength and rigidity by casting or other processes. In this way, the motorcycle frame has higher structural stability and durability.

[0061] The technical features of the above embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.
