DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description herein is for describing the specific embodiments only and is not intended to be limiting of the present application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0029] The present application provides a motorcycle frame compatible with a power battery, and also provides an electric motorcycle 100 comprising a driving motor 60, a power battery 70 and the motorcycle frame compatible with the power battery of the present application, wherein the driving motor 60 drives the wheels instead of an engine, and the power battery 70 provides electric energy for the driving motor 60. Figures 1-2 The electric motorcycle 100 of one embodiment of the present application is shown, Figures 3-4 The motorcycle frame compatible with the power battery of one embodiment of the present application is shown.

[0030] The motorcycle frame compatible with the power battery of the present application (hereinafter referred to as the motorcycle frame for convenience) 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 electric motorcycle 100 of the present application has a sitting height adjustment function, and the sitting height adjustment function changes the height of the seat cushion to adapt the electric motorcycle 100 to consumers with different body sizes.

[0031] Referring to Figures 1-4 Meanwhile, please refer to Figures 5-6The motorcycle frame comprises a front pipe 10, a cage, two groups of motor seats 30, a suspension support 40, a side limiting part 50 and a cushion support platform. The front pipe 10 is provided for a front fork of the electric 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 load-bearing frame 21, a bottom beam 221 and a lower beam 222. The load-bearing frame 21 comprises an upper beam 211 and a rear beam 212. The two ends of the upper beam 211 are respectively connected to the front pipe 10 and the top end of the rear beam 212. 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 to the rear end of the bottom beam 221. The two ends of the lower beam 222 are respectively connected to the front pipe 10 and the front end of the bottom beam 221. The top end and the bottom end of the rear beam 212 are respectively the end of the rear beam 212 relatively far away from the ground and the end of the rear beam 212 relatively close to the ground. 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 3-4 The cage forms a motor mounting space 201 and a battery placement space 202 located obliquely behind the front pipe 10. The oblique rear side 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 electric 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. The motor opening is specifically located between the two bottom beams 221. The battery placement space 202 has a battery opening opening upwardly away from the ground. The battery opening is specifically located between the two upper beams 211. The two groups of motor seats 30 are respectively a front hanger 31 and a rear hanger 32. The front hanger 31 comprises two front seat bodies 311 fixedly connected to the two lower beams 222. The rear hanger 32 comprises two rear seat bodies 321 fixedly connected to the two rear beams 212. The front hanger 31 and the rear hanger 32 are arranged in a length direction of the motor opening. The length direction of the motor opening is the length direction of the bottom beam 221, which is perpendicular to the direction of the rear wheel axis of the electric motorcycle 100. When the electric 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 5-6The driving motor 60 comprises a cylindrical shell and two lugs, i.e., a front lug 611 and a rear lug 612, which are respectively protruded on two opposite half sides of the shell. Each half side is a half circumferential side of the shell, and the two half sides do not overlap and together constitute the entire circumferential side of the shell. The front lug 611 and the front lug seat 31 are detachably connected through a threaded connector or a quick plug-in connector, and the rear lug 612 and the rear lug seat 32 are detachably connected through a threaded connector or a quick plug-in connector. Preferably, the front lug seat 31 and the rear lug seat 32 are both provided with a pin hole 33, the axis of the pin hole 33 extends in the horizontal direction and is perpendicular to the two floor beams 221, and the pin hole 33 allows a bolt or a quick plug-in pin to pass through and extend into the front lug 611 and the rear lug 612. When the quick plug-in pin passes through the pin hole 33 and extends into the front lug 611 and the rear lug 612, a locking mechanism can also be provided to lock the quick plug-in pin, thereby limiting the axial freedom of the quick plug-in pin to prevent it from falling off.

[0034] The motor pass allows the driving motor 60 to pass during disassembly and assembly, so that the driving motor 60 enters or leaves the motor installation space 201. After the front lug 611 and the front lug seat 31 are separated and the rear lug 612 and the rear lug seat 32 are separated, the driving motor 60 can be lifted and moved downward to pass through the motor pass and leave the motor installation space 201. By moving the driving motor 60 downward to remove it, the time required to remove the driving motor 60 can be saved, the moving height of the driving motor 60 to the ground can be reduced, and the user and the maintainer can quickly complete the disassembly and assembly of the driving motor 60. The two spaced motor seats 30 can ensure the rationality of the stress of the driving motor 60 after installation and effectively suppress the shaking and vibration of the driving motor 60. Optionally, the front lug 611 and the rear lug 612 are symmetrically arranged on two opposite half sides of the driving motor 60, and the front lug 611, the rear lug 612, and the output shaft of the driving motor 60 are approximately at the same vertical height. In this way, the front lug 611 and the rear lug 612 apply symmetric forces to the driving motor 60 through the front lug seat 31 and the rear lug seat 32, respectively, and the front lug seat 31 and the rear lug seat 32 can equally share the external force, thereby 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, and a user can take out or put the power battery 70 into the battery accommodation space 202 by holding the handle and driving the power battery 70 through the battery pass-through opening. The suspension support 40 and the cage are in a split forming structure and are fixedly installed, and the side limiting piece 50 and the cage are in a split forming structure and are fixedly installed. The suspension support 40 is located on a side of the suspension support 40 away from the ground and faces the battery pass-through opening. 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 backwardly inclined. An acute angle α is formed between an axis of the front pipe 10 and a horizontal plane, and the acute angle α is directed to a rear of the front pipe 10. An acute angle β is formed between the side limiting piece 50 and the horizontal plane, and the acute angle β is directed to a rear of the side limiting piece 50. The rear of the side limiting piece 50 is a side of the side limiting piece 50 away from the front pipe 10 and close to a rear wheel of the electric motorcycle 100. The acute angle α can be equal to or different from the acute angle β.

[0036] When the power battery 70 is accommodated in the battery accommodation space 202, the suspension support 40 acts on a bottom of the power battery 70, and the side limiting piece 50 acts on a side of the power battery 70 away from the front pipe 10. The suspension support 40 and the side limiting piece 50 cooperatively limit a freedom degree of movement of the power battery 70, so as to avoid shaking of the power battery 70 when the electric motorcycle 100 is driven. When the user holds the handle and drives the power battery 70 through the battery pass-through opening, the side limiting piece 50 can act on a 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 accommodation space 202 along an inclined direction of the side limiting piece 50. The inclined direction of the side limiting piece 50 enables the side limiting piece 50 to apply a supporting force to the side of the power battery 70, so as to reduce a lifting force applied by the user to the handle, and enable the user to take out or put the power battery 70 more easily and labor-savingly. In addition, the guiding action of the side limiting piece 50 on the power battery 70 can protect the power battery 70 from being impacted against the cage or being scraped against the frame 20 due to tilting, and protect the power battery 70.

[0037] In some embodiments, the cage includes a plurality of BIK500 steel pipes which jointly form the motor accommodation space 201 and the battery accommodation 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 BIK500 steel pipes. In this way, the structural strength and durability of the cage can be ensured while the weight of the cage is reduced, and the motorcycle frame is lightened.

[0038] Referring to Figures 2-6The upper beam 211 protrudes from the side of the front tube 10 and extends rearward of the front tube 10, and the extension state of the upper beam 211 is specifically that the height of the upper beam 211 from the ground changes in a decreasing trend in a direction away from the front tube 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 defining a mounting position as a whole unit and forming detachable connection with the cushion support platform, and the height of the plurality of mounting positions from the ground changes in a decreasing trend along the extension direction of the load-bearing frame 21, which includes the extension direction of the upper beam 211, the upper beam 211 extending away from the front tube 10 and gradually approaching the ground. When the cushion support platform is connected with any group of mounting portions, the position of the cushion support platform at this time is the mounting position of this group of mounting portions. Therefore, the motorcycle frame provides a plurality of mounting 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, and by switching the mounting portions connected with the cushion support platform, the cushion support platform can be transferred from the mounting position defined by the mounting portions before disassembly to a new mounting position, and the height of the cushion on the cushion support platform also changes accordingly. Figure 1 and Figure 9 respectively illustrate two different sitting heights of the electric motorcycle 100, and Figure 1 compared with Figure 9 the electric motorcycle 100 shown in the figure has a raised sitting height.

[0039] Optionally, the motor installation space 201 is entirely located within the envelope space of the cage, so that the driving motor 60 is entirely located within the envelope space of the cage. Preferably, referring to Figure 9 In some embodiments, the motorcycle frame further includes a frame cover 90, which is detachably provided on the hollow hole of the cage to close the motor installation space 201, and the frame cover 90 improves the appearance of the electric motorcycle 100 and can protect the driving motor 60. When the driving 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 installation 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 driving motor 60 is reinstalled into the motor installation space 201, the frame cover 90 is re-provided on the hollow hole of the cage. The driving motor 60 entirely located within the envelope space of the cage does not interfere with the frame cover 90.

[0040] Referring to Figures 3-6In some embodiments, the enclosure further comprises a support 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 24 are connected to the two rear beams 212 respectively, or the two ends of the support 24 are connected to the two bottom beams 221 respectively. The two ends of the reinforcing column 25 are connected to the two upper beams 211 respectively, or the two ends of the reinforcing column 25 are connected to the two rear beams 212 respectively. The two ends of the reinforcing beam 26 are connected to the two lower beams 222 respectively. In this way, the distance between the two groups of frames 20 is fixed, and the rigidity and strength of the entire enclosure are significantly improved. The support 24, the reinforcing column 25 and the reinforcing beam 26 can be BIK500 steel pipes. The support 24 and the reinforcing column 25 can be two columnar structures extending along a horizontal straight line, and the length direction of the two columnar structures can be perpendicular to the length direction of the bottom beam 221. The length direction of the support 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. Therefore, the two groups of frames 20 are 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. 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 pass-through formed on the side of the support 24 facing away from the rear wheel of the electric motorcycle 100. In addition, 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 arranged at intervals 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 installation space 201 until the drive motor 60 abuts against the support 24. 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 disassembling the drive motor 60 and the motorcycle frame, 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 a tensioned state to a relaxed state. The support 24 temporarily supports the drive motor 60, which facilitates the user to continue disassembling 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 referring to Figures 1-3 , Figures 5-6The distance between the two front seat bodies 311 connected to the two lower beams 222 is d1, the distance between the two rear seat bodies 321 connected to the two rear beams 212 is d2, d1 < d2, the difference between d2 and d1 is Δd, and the two rear hangers 32 form a receiving gap therebetween; the electric motorcycle 100 further comprises wheel swing arms 80 on which the rear wheels are mounted, the rear ends of the wheel swing arms 80 are provided with wheel bearings for connecting the rear wheels, the two front ends of the wheel swing arms 80 extend into the two rear hangers 32, the two ends of the rear hanger 612 of the driving motor 60 are respectively provided with the two front ends of the wheel swing arms 80, at this time, the rear hanger 612 and the two front ends of the wheel swing arms 80 located at the two ends of the rear hanger 612 are all located in the receiving gap and are penetrated by the same pin shaft, the two ends of the pin shaft extend into the pin holes 33 of the two rear hangers 32, thus allowing the wheel swing arms 80 to rotate around the center lines of the rear hangers 32, and the total width of the ends of the wheel swing arms 80 located in the receiving gap is Δd, which is the sum of the widths of the two front ends of the wheel swing arms 80. In this way, the rotation connection of the wheel swing arms 80 to the cage and the installation of the driving motor 60 are simultaneously realized by one pin shaft, the structure of the motorcycle frame and the electric motorcycle 100 is simplified, and the production cost of the motorcycle frame is reduced.

[0043] Further, referring to Figures 3-4 The front hanger 31 further comprises a seat bracket 312, one side of the seat bracket 312 is fixedly connected to the front seat body 311, and the other side of the seat bracket 312 forms a connecting pipe side, the connecting pipe side 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 distance between the two front seat bodies 311 connected to the two seat brackets 312 is d1. Alternatively, the seat bracket 312 and the front seat body 311 are integrally formed, 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 the end of the seat bracket 312 connected to the front seat body 311 to the connecting pipe side. In this way, after the front hanger 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 side, and the increased length of the connecting pipe side 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 side and ensuring reliable connection of the front hanger 31.

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

[0045] Referring to Figures 1-2 , Figures 5-6 , and referring to Figures 7-8 , the suspension support 40 is installed on the reinforcing beam 26 by a fastener and includes a suspension plate 41, the suspension plate 41 is arranged obliquely, and the side of the suspension plate 41 away from the ground faces the battery passing opening, the side limiting piece 50 includes a partition plate 52 fixedly connected to the reinforcing column 25, the partition plate 52 is inclined 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 piece 50, specifically, the side of the partition plate 52 away from the front pipe 10 and close to the rear wheel of the electric motorcycle 100, the angle α and the angle β can be equal or unequal. The suspension plate 41, the partition plate 52, and the frame cover 90 covering the cage jointly enclose to form a battery arrangement space 202, the battery arrangement space 202 corresponds to the angle space between the suspension plate 41 and the partition plate 52, the angle space is the angle space between the suspension support 40 and the side limiting piece 50, and the angle opening between the suspension plate 41 and the partition plate 52 is arranged away from the ground. When the power battery 70 is arranged in place in the battery arrangement space 202, the suspension plate 41 contacts the bottom of the power battery 70, the partition plate 52 contacts the side of the power battery 70 away from the front pipe 10, and the power battery 70 reacts 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 away from the front pipe 10. The side of the partition plate 52 away from the battery arrangement 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 passing opening along the inclined direction of the partition plate 52.

[0046] Specifically, the side limiting member 50 comprises a ground proximal end extending towards the suspension support 40 and relatively close to the ground, and a ground distal end extending towards the battery passageway and relatively far from the ground. The suspension support plate 41 comprises a front support end 411 relatively far from the ground proximal end of the side limiting member 50, and a rear support end 412 relatively close to the ground proximal end of the side limiting member 50. The ground clearance of the suspension support 40 is the distance between the suspension support plate 41 and the horizontal ground. 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 support plate 41, and the suspension support plate 41 is thus parallel to the battery passageway. The extension direction of the partition plate 52 is approximately perpendicular to the suspension support plate 41. Thus, the side limiting member 50 guides the power battery 70 to move into and out of the battery accommodation space 202 along the vertical direction of the suspension support plate 41. When the power battery 70 slides along the partition plate 52 to the lowest position while maintaining the state of adhering to the partition plate 52, the bottom of the power battery 70 directly adheres to the side of the suspension support plate 41 facing away from the ground.

[0047] Referring to Figures 7-8 In some embodiments, the side limiting member 50 further comprises a special-shaped portion 51. An end of the partition plate 52 relatively close to the ground extends towards the suspension support 40 as the ground proximal end of the side limiting member 50. The special-shaped portion 51 is fixedly connected to an end of the partition plate 52 relatively far from the ground, and extends towards 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. 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 motor scooter 100. The installation of the side limiting member 50 and the cage is simpler. It is only necessary to press the special-shaped portion 51 to press the reinforcing column 25 into the arc-shaped slot 511. When the side limiting member 50 and the cage are detached, it is only necessary to apply a lifting force to the special-shaped portion 51 in a direction away from the suspension support 40 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 difficulty of forming the motorcycle frame and the production cost.

[0048] It can be understood that, in other embodiments, a clamping slot can be formed on the reinforcing column 25. The special-shaped portion 51 is detachably inserted into the clamping slot. When the side limiting member 50 is detached, a lifting force is applied to the special-shaped portion 51 in a direction away from the suspension support 40, and the special-shaped portion 51 is pulled out of the clamping slot to detach the special-shaped portion 51 and the reinforcing column 25. 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 flange 42 and a flared edge 43, the limiting flange 42 is connected to the edge of the suspension plate 41 by bending and extends towards the battery overpass, the suspension plate 41 and the limiting flange 42 form a limiting cavity, after the power battery 70 is placed in position in the battery placement space 202, at least part of the power battery 70 including the bottom of the power battery 70 is located in the limiting cavity, the limiting flange 42 limits the power battery 70 from shaking by stopping the outer circumferential side of the power battery 70, optionally, the limiting flange 42 is perpendicular to the suspension plate 41, so that the space occupied by the limiting cavity is approximately a cuboid, in this way, the power battery 70 with a cuboid structure can be adapted, the flared edge 43 is connected to the edge of the limiting flange 42 away from the suspension plate 41 by bending, and inclines to the outside of the limiting flange 42 in a direction away from the opening of the limiting cavity, the flared edge 43 forms a flared portion with the edge of the limiting flange 42 away from it, so that the power battery 70 enters the limiting cavity under the guidance of the flared edge 43.

[0050] Further, referring to Figures 7-8 , at least part of the side limiting member 50 including the end of the partition plate 52 away from the special-shaped portion 51 extends into the limiting cavity, the limiting flange 42 is further provided with a hooking groove 421 communicating with the limiting cavity, the part of the side limiting member 50 located in the limiting cavity extends into the hooking groove 421 and hooks the limiting flange 42, the side limiting member 50 located in the limiting cavity can be clamped and fixed by the power battery 70 and the limiting flange 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. Optionally, the end of the partition plate 52 away from the special-shaped portion 51 forms a curled hooking edge, which extends into the hooking groove 421 and hooks the limiting flange 42. In this way, the side limiting member 50 and the suspension support 40 are detachably hooked, the setting of the hooking groove 421 simplifies the structure of the side limiting member 50 and makes it easier to be molded, and it is easier to disassemble and assemble the side limiting member 50 and the suspension support 40.

[0051] Further, referring to Figures 5-6 , the distance from the side of the side limiting member 50 away from the front pipe 10 and the battery placement space 202 to the rear beam 212 changes in an increasing trend along the direction close to the bottom beam 221 and the motor overpass, in this way, the size of the motor installation space 201 in the length direction of the motor overpass changes in an increasing trend along the direction close to the ground, the driving motor 60 located in the motor installation space 201 can be arranged closer to the motor overpass and the ground, thereby being beneficial to reduce the overall height of the center of gravity of the electric motorcycle 100 and improve the driving performance of the electric motorcycle 100, in addition, the motor installation space 201 required by the driving motor 60 and the battery placement space 202 required by 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, thereby reducing the envelope space of the motorcycle frame and realizing efficient use of the internal space of the motorcycle frame.

[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 slides in 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 is more labor-saving when taking and placing the power battery 70. The entire battery placement space 202 is approximately an inclined extension passage, and the inclined direction of the side limiting part 50 is the inclined direction of the passage, so that 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 when taking and placing 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, lowering the cushion height can be achieved by shifting the cushion support platform from the first mounting position to the second mounting position, and vice versa. Figure 1 The electric motorcycle 100 shown corresponds to the cushion support platform being in the first mounting position, Figure 9 The electric 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 cushion angle 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, 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 connector, detachable connection through a quick plug connector, plug-in connection, etc. When the cushion support and the plurality of mounting portions are connected by the threaded connector, a dismounting tool is needed to apply force to the threaded connector. When the quick plug connector or the plug-in connection is used, no dismounting tool is needed, and the user can manually detach and reconnect 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 for the threaded connector or the quick plug connector to pass through.

[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 easily disassemble and assemble the electric motorcycle 100, 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 upward and obliquely. 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 there is no need to detach the cushion support 28 from the load-bearing frame 21, and it is easier to detach the front protective shell 27 alone.

[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 electric 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 sitting position change experience for the user. The plurality of mounting portions can be arranged on the upper beam 211, or on the rear beam 212, or on both 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 stronger 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.
