[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0031] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0032] like Figure 1 As shown, the present application provides a two-wheeled vehicle 100, which includes basic components of the vehicle, such as: a frame 10, a suspension 20, a running mechanism 30, a steering device 40 and a pedal device 50. Specifically, the frame 10 constitutes the main framework of the two-wheeled vehicle 100, and the suspension 20 includes a front suspension 21 and a rear suspension 22, wherein the front suspension 21 is fixedly mounted on the front portion of the frame 10, and the rear suspension 22 is fixedly mounted on the rear portion of the frame 10. At least a portion of the running mechanism 30 is connected to the frame 10 via the front suspension 21. At least a portion of the steering device 40 is disposed on the front suspension 21, and the direction of the running mechanism 30 is controlled by the front suspension 21. The pedal device 50 is provided for the driver to step on, and is provided at the lower portion of the frame 10. In order to clearly illustrate the technical solution of the present application, the following is also provided. Figure 1 The up-down, left-right, and front-back directions shown are the up-down, left-right, and front-back directions of the two-wheeled vehicle 100 .

[0033] like Figure 2 As shown, as an implementation, the steering device 40 includes a connecting plate 41, a steering mounting member 42, a steering handle 43 and a lifting drive assembly 44.

[0034] The connecting plate 41 is installed on the front suspension 21. The suspension 20 includes two left and right front suspensions 21. At least part of the connecting plate 41 is located between the left and right front suspensions 21. The suspension 20 includes a first connecting plate 411 and a second connecting plate 412 distributed along the height direction of the two-wheeled vehicle 100, wherein the first connecting plate 411 is arranged above the second connecting plate 412.

[0035] The steering mounting member 42 includes an adjusting portion 421 and a mounting portion 422. In the example of the present application, the adjusting portion 421 is a cylindrical long rod, the adjusting portion 421 extends along a preset direction and is inserted through the first connecting plate 411, and the mounting portion 422 is disposed at one end of the adjusting portion 421 away from the second connecting plate 412 and is fixedly connected to the adjusting portion 421. The left and right adjusting portions 421 are fixed by the mounting portion 422 to form a steering mounting member 42 that can be integrally linked.

[0036] The steering handle 43 is fixedly mounted on the steering mounting member 42 . When the adjusting portion 421 slides up and down relative to the first connecting plate 411 along a preset direction, the steering handle 43 which is relatively fixed to the steering mounting member 42 can achieve height adjustment.

[0037] One end of the lifting drive assembly 44 is movably connected to the second connecting plate 412, and the other end is movably connected to the mounting portion 422, and acts on the mounting portion 422 to drive the steering mounting member 42 to move relative to the first connecting plate 411 along a preset direction, thereby adjusting the height of the steering handle 43.

[0038] In order to clearly illustrate the technical solution of the present application, the following are provided respectively: Figure 2 and Figure 3 The schematic diagram of the steering device 40 shown, Figure 2 It is shown that the steering handle 43 is in the highest position under the action of the lifting drive assembly 44. Figure 3 It is shown that the steering handle 43 is in the lowest position under the action of the lifting drive assembly 44.

[0039] Through the above arrangement, the driver can select a suitable height of the steering handle 43 according to the driving posture or the driver's height, thereby improving driving comfort.

[0040] In the example of the present application, the steering device 40 includes a lifting drive assembly 44 arranged between the left and right front suspensions 21, so as to reduce the number of components of the steering device 40, and because one lifting drive assembly 44 can meet the height adjustment of the steering handle 43, so that the space between the first connecting plate 411 and the second connecting plate 412 is more ample, which is conducive to the wiring harness layout and reduces the weight and cost of the vehicle.

[0041] like Figure 4As shown, the extension direction of the front suspension 21 is defined as a first extension direction 201, the extension direction of the lifting drive assembly 44 is defined as a second extension direction 401, and an angle α is formed between the first extension direction 201 and the second extension direction 401. As an implementation, the angle α between the first extension direction 201 and the second extension direction 401 is greater than or equal to 5° and less than or equal to 10°. Further, the angle α between the first extension direction 201 and the second extension direction 401 is greater than or equal to 6° and less than or equal to 9°. More preferably, the angle α between the first extension direction 201 and the second extension direction 401 is equal to 7°. It should be noted that if the angle α between the first extension direction 201 and the second extension direction 401 is too small, the extension direction of the lifting drive assembly 44 is substantially parallel to the extension direction of the front suspension 21, the lifting drive assembly 44 is located between the left and right front suspensions 21, or there is a possibility of mutual interference between the lifting drive assembly 44 and the adjustment portion 421. If an extension section protruding toward the front of the two-wheeled vehicle 100 is provided on the second connecting plate 412 to fix the lifting drive assembly 44 to avoid interference between the lifting drive assembly 44 and its surrounding components, the space at the front of the frame 10 will be more compact, which is not conducive to vehicle assembly. In addition, if the angle α between the first extension direction 201 and the second extension direction 401 is too large, the structural compactness of the connection between the steering device 40 and the front suspension 21 will be reduced. Through the above arrangement, while taking into account the compactness of the vehicle structure, interference between related components during the adjustment of the steering handle 43 is avoided.

[0042] It should be noted that during the manufacturing and assembly process of the entire vehicle, there are manufacturing errors and assembly errors in the parts. Through the above-mentioned assembly form, that is, there is an angle α between the lifting drive component 44 and the front suspension 21, and the two ends of the lifting drive component 44 are respectively movably connected to the mounting portion 422 and the second connecting plate 412, which effectively avoids the jamming of the steering handle 43 during the adjustment process caused by production and manufacturing errors, so that the adjustment of the steering handle 43 is smoother.

[0043] like Figure 5 and Figure 6 As shown, as an implementation, the mounting portion 422 has a mounting groove 4221 with an opening facing downward, and at least a portion of the adjustment portion 421 is inserted into the mounting groove 4221 and fastened by fasteners so that the adjustment portion 421 and the mounting portion 422 remain relatively fixed.

[0044] Specifically, a rubber buffer 423 is provided between the adjusting portion 421 and the mounting groove 4221. The buffer 423 may be a collar, which is circumferentially distributed on the outer edge of the adjusting portion 421 to absorb vibrations generated when the vehicle is running, thereby reducing friction between mechanical structures. In addition, the buffer 423 may also reduce wear between the first connecting plate 411 and the adjusting portion 421.

[0045] like Figure 5 As shown, as an implementation method, the lifting drive assembly 44 is movably connected to the second connecting plate 412 through the first pin shaft 45, and the first pin shaft 45 is penetrated through the lifting drive assembly 44 and the second connecting plate 412 along the width direction of the two-wheeled vehicle 100. So that the lifting drive assembly 44 can rotate relative to the second connecting plate 412 around the axis of the first pin shaft 45.

[0046] For example, during the assembly of the lifting drive assembly 44, one end of the lifting drive assembly 44 is fixed to the second connecting plate 412 via the first pin shaft 45. Since the lifting drive assembly 44 and the second connecting plate 412 can move relative to each other via the first pin shaft 45, the problem of difficulty in assembling the lifting drive assembly 44 due to production errors is avoided. In addition, the above arrangement can also avoid the problem of stress between the lifting drive assembly 44 and the second connecting plate 412 being unable to be released due to vehicle vibration.

[0047] It should be noted that, since the extension direction of the first pin shaft 45 is substantially parallel to the width direction of the two-wheeled vehicle 100 , it is convenient to assemble the lifting drive assembly 44 .

[0048] like Figure 5 As shown, further, the lifting drive assembly 44 is movably connected to the mounting portion 422 through a second pin shaft 46, and the second pin shaft 46 is arranged through the lifting drive assembly 44 and the mounting portion 422 along the length direction of the two-wheeled vehicle 100. So that the lifting drive assembly 44 can rotate relative to the mounting portion 422 around the second pin shaft 46.

[0049] For example, during the assembly of the lifting drive assembly 44, one end of the lifting drive assembly 44 is first fixed to the second connecting plate 412 via the first pin shaft 45, and then the other end of the lifting drive assembly 44 is fixed to the mounting portion 422 via the second pin shaft 46. The lifting drive assembly 44, which is movable at both ends, does not need to perform cumbersome positioning steps during the assembly process, which simplifies the assembly difficulty of the lifting drive assembly 44 and avoids the problem of difficulty in assembling the lifting drive assembly 44 due to production errors.

[0050] It should be noted that, since the steering handle 43 is distributed on the left and right sides of the mounting portion 422 , the second pin shaft 46 extending along the length direction of the two-wheeled vehicle 100 can prevent the steering handle 43 from interfering with the lifting drive assembly 44 during assembly.

[0051] like Figure 5 As shown, as an implementation method, the lifting drive assembly 44 includes a screw rod 441 and a motor 442 that drives the screw rod 441. Here, the motor 442 includes a motor body and a sleeve surrounding the outside of the motor body. At least a portion of the screw rod 441 is inserted into the sleeve and is transmission-connected to the motor body.

[0052] It should be noted that the extension direction of the screw rod 441 is the extension direction of the connecting rod driving assembly described above.

[0053] Specifically, the motor 442 is mounted on the second connecting plate 412 and is movably connected to the second connecting plate 412 via the first pin 45. One end of the screw rod 441 away from the motor 442 is movably connected to the mounting portion 422 via the second pin 46.

[0054] like Figure 7 As shown, the present application provides a first embodiment of a pedal device 50, which includes a connecting rod driving assembly 51, a pedal connecting rod assembly 52 and a foot pedal 53. At least part of the connecting rod driving assembly 51 is fixedly mounted on the frame 10 and movably connected to the pedal connecting rod assembly 52, and the foot pedal 53 is arranged on the pedal connecting rod assembly 52. ​​The connecting rod driving assembly 51 acts on the pedal connecting rod assembly 52, drives the pedal connecting rod assembly 52 to drive the foot pedal 53 to move, and changes the height of the foot pedal 53 from the ground. The pedal device 50 with adjustable height of the foot pedal 53 from the ground can adapt to drivers of different heights, or adapt to different riding postures of the driver, thereby improving the comfort of the driver during riding.

[0055] like Figure 8 As shown, specifically, the pedal connecting rod assembly 52 includes at least a first pedal connecting rod 521, wherein the first pedal connecting rod 521 is rod-shaped and has a first end and a second end relatively arranged, the first end of the first pedal connecting rod 521 is movably connected to the connecting rod driving assembly 51, and the foot pedal 53 is arranged at the second end of the first pedal connecting rod 521.

[0056] Here, the active connection between the first pedal connecting rod 521 and the connecting rod driving assembly 51 indicates that the first pedal connecting rod 521 and the connecting rod driving assembly 51 can rotate relative to each other. The specific connection structure to realize the above connection method can be a hinge, a rotating shaft connection, a bearing connection, a joint ball head connection, etc. between the two.

[0057] In the example of the present application, the pedal link assembly 52 also includes a rotating shaft 522 passing through the first pedal link 521. The first pedal link 521 is connected to the frame 10 through the rotating shaft 522 and can rotate relative to the frame 10 around the axis of the rotating shaft 522 under the action of the connecting rod driving assembly 51.

[0058] Exemplarily, when the connecting rod driving assembly 51 acts on the first end of the first pedal connecting rod 521 to raise the first end of the first pedal connecting rod 521, the foot pedal 53 disposed at the second end of the first pedal connecting rod 521 is lowered. It can be understood that when the connecting rod driving assembly 51 acts on the first end of the first pedal connecting rod 521 to lower the first end of the first pedal connecting rod 521, the foot pedal 53 disposed at the second end of the first pedal connecting rod 521 is raised.

[0059] Furthermore, when the connecting rod driving assembly 51 acts on the first end of the first pedal connecting rod 521 to make the first pedal connecting rod 521 rotate relative to the frame 10 around the axis of the rotating shaft 522, the connecting rod driving assembly 51 can stop at any position between its minimum stroke and maximum stroke, thereby realizing stepless adjustment of the foot pedal 53.

[0060] It should be noted that, under the action of the connecting rod driving assembly 51, the first pedal connecting rod 521 drives the pedal 53 to move, thereby changing the height of the pedal 53 from the ground. When the driver steps on the pedal 53, the force applied by the driver to the pedal device 50 is mainly borne by the connecting rod driving assembly 51. Therefore, the connecting rod driving assembly 51 is made of a material with high structural strength, such as metal alloy, tempered steel, etc. The specific type of the metal alloy material is not limited, and any metal alloy that can meet the strength requirements is within the scope of protection of the technical solution of this application.

[0061] Through the above arrangement, under the premise of ensuring the structural strength of the connecting rod driving assembly 51, the structural complexity of the pedal device 50 can be greatly reduced, the assembly difficulty of the foot pedal 53 with height adjustment function can be reduced, and maintenance can be more convenient.

[0062] like Figure 8 As shown, as an implementation, the pedal link assembly 52 further includes a second pedal link 523 and a third pedal link 524, and the first pedal link 521, the second pedal link 523 and the third pedal link 524 are movably connected in sequence.

[0063] like Figure 7 As shown, the frame 10 includes a pedal link mounting area 11 for mounting a third pedal link 524, and the third pedal link 524 is movably connected to the frame 10 via the pedal link mounting area 11, so that the distance between the second end of the first pedal link 521 and the pedal link mounting area 11 increases or decreases with the rotation of the first pedal link 521.

[0064] When adjusting the height of the pedal 53 from the ground, the pedal 53 moves in a circle with the axis of the rotating shaft 522 as the center of rotation, so the distance between the pedal 53 and the pedal link installation area 11 increases or decreases simultaneously with the change of the height of the pedal 53 from the ground. By providing the second pedal link 523 and the third pedal link 524 that can rotate relatively, when the height of the pedal 53 from the ground is at the highest point, the extension directions of the second pedal link 523 and the third pedal link 524 are basically coincident, and when the height of the pedal 53 from the ground is gradually adjusted downward from the highest point, the angle between the second pedal link 523 and the third pedal link 524 is gradually reduced, thereby avoiding structural deformation caused by mutual compression between the first pedal link 521, the second pedal link 523 and the third pedal link 524.

[0065] In addition, by providing the second pedal link 523 and the third pedal link 524 , the rigidity of the pedal link assembly 52 in the height direction of the two-wheeled vehicle 100 is increased, and part of the force applied by the driver through the pedal 53 is borne, thereby avoiding damage to the link drive assembly 51 .

[0066] In the example of the present application, the fixed point where the first foot pedal link 521 and the second foot pedal link 523 are connected is defined as the common node of the first foot pedal link 521 and the second foot pedal link 523, and the foot pedal 53 is arranged at the common node of the first foot pedal link 521 and the second foot pedal link 523. The mounting bolts of the foot pedal 53 are reused as the mounting bolts of the first foot pedal link 521 and the second foot pedal link 523, thereby improving the compactness of the overall structure of the foot pedal device 50 and the number of parts of the foot pedal device 50, thereby reducing costs.

[0067] like Figure 8As shown, the rotating shaft 522 is basically located in the middle of the first pedal connecting rod 521, and the first pedal connecting rod 521 is divided into a first section and a second section, wherein the portion between the rotating shaft 522 and the first end of the first pedal connecting rod 521 is the first section, and the portion between the rotating shaft 522 and the second end of the first pedal connecting rod 521 is the second section. As an implementation, the length ratio between the length D1 of the first section and the length D2 of the second section is greater than or equal to 0.8 and less than or equal to 1.2. Further, the length ratio between the length D1 of the first section and the length D2 of the second section is greater than or equal to 0.9 and less than or equal to 1.1. More preferably, the length ratio between the length D1 of the first section and the length D2 of the second section is equal to 1. It should be noted that if the length ratio between the first section and the second section is too large, the connecting rod driving assembly 51 needs to have a larger adjustment stroke when adjusting the height of the pedal 53 from the ground; if the length ratio between the first section and the second section is too small, the connecting rod driving assembly 51 needs to bear too much force exerted by the driver on the pedal 53. Through the above arrangement, while taking into account the rationality of the adjustment stroke of the connecting rod driving assembly 51, it is also possible to reduce the force applied to the connecting rod driving assembly 51, thereby improving the rationality of the overall vehicle layout.

[0068] As another optional implementation, the pedal link assembly 52 includes a first pedal link 521 and a telescopic link with adjustable length (not shown in the figure). The first pedal link 521 is connected to the frame 10 via a rotating shaft 522 and can rotate relative to the frame 10 around the axis of the rotating shaft 522 under the action of the link driving assembly 51. The first end of the first pedal link 521 is movably connected to the link driving assembly 51, one end of the telescopic link is movably connected to the second end of the first pedal link 521, and the other end of the telescopic link is movably connected to the frame 10 via the pedal link installation area 11, so that the distance between the second end of the first pedal link 521 and the link installation area increases or decreases with the rotation of the first pedal link 521.

[0069] When adjusting the height of the pedal 53 from the ground, the pedal 53 moves in a circle with the axis of the rotating shaft 522 as the center of rotation, so the distance between the pedal 53 and the pedal link mounting area 11 increases or decreases simultaneously with the change of the height of the pedal 53 from the ground. By setting a telescopic link with adjustable length, when the height of the pedal 53 from the ground is at the highest point, the telescopic link is at a first length, and when the height of the pedal 53 from the ground is gradually adjusted downward from the highest point to the lowest point, the telescopic link is gradually shortened from the first length until the telescopic link is at a second length, wherein the first length is greater than the second length. This avoids structural deformation between the first pedal link 521 and the telescopic link due to mutual compression.

[0070] Exemplarily, the telescopic connecting rod at least includes a sleeve and an inner tube that passes through the inner tube of the sleeve and can move relative to the sleeve.

[0071] In addition, the rigidity of the pedal link assembly 52 in the height direction of the two-wheeled vehicle 100 is increased by providing a telescopic link, so that part of the force applied by the driver through the pedal 53 is borne, thereby avoiding damage to the link drive assembly 51.

[0072] like Figure 8 As shown, as an implementation method, the connecting rod drive assembly 51 includes a motor 511 and a screw rod 512 transmission-connected to the motor 511, the motor 511 is mounted on the frame 10, the screw rod 512 extends toward the upper rear of the two-wheeled vehicle 100, and is movably connected to the first pedal connecting rod 521.

[0073] Exemplarily, the motor 511 acts on the screw rod 512 to extend or shorten the length of the screw rod 512. When the screw rod 512 is extended, the first end of the first pedal link 521 moves upward under the action of the screw rod 512, and the second end of the first pedal link 521 moves downward, thereby reducing the height of the footrest 53 from the ground. When the screw rod 512 is shortened, the first end of the first pedal link 521 moves downward under the action of the screw rod 512, and the second end of the first pedal link 521 moves upward, thereby raising the height of the footrest 53 from the ground.

[0074] In the example of the present application, the screw rod 512 can be parked at any position between its minimum stroke and maximum stroke to achieve stepless adjustment of the foot pedal 53. It should be noted that since the connecting rod drive assembly 51 needs to bear part of the force applied by the driver to the foot pedal 53, in order to ensure the stability of the foot pedal 53, the screw rod 512 needs to meet a certain structural strength, and the connection structure between the screw rod 512 and the motor 511 also needs to have a certain strength.

[0075] For example, the screw rod 512 may be made of HRC45 or higher tempered steel, or any alloy material whose hardness meets the above requirements. The sleeve sleeved on the outside of the screw rod 512 is made of 6061-T6 (aluminum, magnesium, silicon alloy, a heat-treated corrosion-resistant alloy with good strength, corrosion resistance, and uniformity).

[0076] This application also provides Fig. 9 In the motion track diagram of the pedal device 50 shown in FIG. 5 , the pedal link assembly 52 changes the height of the pedal board 53 under the action of the link driving assembly 51. At this time, the first pedal link 521 rotates around the axis of the rotating shaft 522. When the pedal board 53 is raised to the highest position under the action of the first pedal link 521, the extension directions of the second pedal link 523 and the third pedal link 524 coincide, that is, the angle between the two is equal to 180°; when the pedal board 53 is raised to the lowest position under the action of the first pedal link 521, the angle formed by the second pedal link 523 and the third pedal link 524 is the smallest.

[0077] like Fig.10 As shown, as an implementation, the two-wheeled vehicle 100 further includes a body controller 60, which is used to control an electronic control unit (ECU) of the body electrical system, and its common functions include controlling headlights, turn signals, anti-theft locking system, central locking, etc. In the example of the present application, the body controller 60 is also used to control the ground clearance of the footrest device 50 and / or the steering device.

[0078] The two-wheeled vehicle 100 also includes a control unit 70 electrically connected to the body controller 60. The control unit 70 may be a button or a display screen with a touch function. The form of the control unit 70 is not specifically limited. In the example of the present application, the driver's touch operation on the control unit 70 can generate an adjustment instruction. The body controller 60 obtains and identifies the adjustment instruction, generates a corresponding control signal according to the adjustment instruction, and then controls the connecting rod drive assembly 51 and / or the lifting drive assembly 44. It should be noted that Fig. 9 The arrows in the figure indicate the transmission direction of instructions and signals.

[0079] For example, the vehicle body controller 60 can independently control the connecting rod driving assembly 51 or the lifting driving assembly 44 in response to the driver's touch operation on the control unit 70. That is, when the height of the foot pedal 53 from the ground remains unchanged, the steering handle 43 is controlled to rise or fall, and vice versa.

[0080] In other examples, the vehicle body controller 60 can store the working positions of the foot pedal 53 and the steering handle 43 preset by the driver, wherein the working position can be at least one, in which the height of the foot pedal 53 from the ground is different, or the height of the steering handle 43 from the ground is different, or the spacing between the foot pedal 53 and the steering handle 43 along the length direction of the two-wheeled vehicle 100 is different. The vehicle body controller 60 can select one working position from the multiple working positions in response to the driver's touch operation on the control unit 70.

[0081] In other examples, the body controller 60 can generate a corresponding control signal in response to the driver's touch operation on the control unit 70, and simultaneously send the control signal to the connecting rod drive assembly 51 and the lifting drive assembly 44, so as to adjust the foot pedal 53 and the steering handle 43 in a linked manner.

[0082] like Fig.11 As shown, the present application also provides a second embodiment of a pedal device 80 , which includes a limiting guide rail 81 , a connecting rod driving assembly 82 , a pedal connecting rod assembly 83 and a foot pedal 84 .

[0083] The limiting guide rail 81 is installed on the frame 10 and extends along a set direction. In the example of the present application, the setting direction is to extend toward the rear lower part of the two-wheeled vehicle 100.

[0084] The connecting rod driving assembly 82 has a first end and a second end that are arranged opposite to each other. The first end of the connecting rod driving assembly 82 is fixedly mounted on the vehicle frame 10, and the second end of the connecting rod driving assembly 82 is movably connected to the limiting guide rail 81. At least a portion of the connecting rod driving assembly 82 can be extended or shortened along a set direction. During the process of extending or shortening the connecting rod driving assembly 82, the second end of the connecting rod driving assembly 82 can slide relative to the limiting guide rail 81 along the set direction.

[0085] The pedal connecting rod assembly 83 includes a plurality of pedal connecting rods movably connected in sequence. The pedal connecting rods at the head and tail ends are movably connected to the frame 10. The connection point of two adjacent pedal connecting rods is defined as a common node of the two pedal connecting rods. Any common node is movably connected to the second end of the connecting rod driving assembly 82.

[0086] Here, the common node of the two adjacent pedal links is movably connected to the second end of the connecting rod driving assembly 82, indicating that the common node of the two adjacent pedal links and the connecting rod driving assembly 82 can rotate relative to each other. The specific connection structure to realize the above connection method can be a hinge, a rotating shaft connection, a bearing connection, a joint ball head connection, etc. between the two.

[0087] The foot pedal 84 is installed on any foot pedal connecting rod. In the example of the present application, the foot pedal 84 is arranged at the common node of two adjacent foot pedal connecting rods, and the installation position of the foot pedal 84 does not overlap with the installation position of the second end of the connecting rod driving assembly 82.

[0088] like Fig.11 As shown, as an implementation method, the pedal device 80 also includes a push rod structure 85 arranged between the pedal connecting rod assembly 83 and the connecting rod driving assembly 82, one end of the push rod structure 85 is movably connected to the second end of the connecting rod driving assembly 82, and the other end is movably connected to the pedal connecting rod assembly 83, and is arranged at a common node of two adjacent pedal connecting rods.

[0089] like Fig.12 As shown, specifically, the pedal device 80 further includes a slider 86 that passes through the limiting guide rail 81 along the width direction of the two-wheeled vehicle 100, and the slider 86 is reused as a connecting member of the limiting guide rail 81, the connecting rod driving assembly 82 and the push rod structure 85. The slider 86 passes through the limiting guide rail 81, the second end of the connecting rod driving assembly 82 and the push rod structure 85 along the width direction of the two-wheeled vehicle 100. When the connecting rod driving assembly 82 is extended, the push rod structure 85 drives the pedal connecting rod assembly 83 to move under the action of the connecting rod driving assembly 82, thereby changing the position of the foot pedal 84.

[0090] The slider 86 may be a bolt, a pin, a connecting shaft, etc.

[0091] Further, the foot pedal 84 includes a first fixed position and a second fixed position. When the connecting rod drive assembly 82 is shortened and the stroke of the connecting rod drive assembly 82 is the shortest, the foot pedal 84 is in the first fixed position (see Fig.11 When the connecting rod drive assembly 82 is extended and the stroke of the connecting rod drive assembly 82 is the longest, the foot pedal 84 is in the second fixed position (see Fig.13 ). Wherein, the height of the first fixed position from the ground is lower than the height of the second fixed position from the ground.

[0092] In the example of the present application, in order to reduce the force on the connecting rod drive assembly 82, the setting direction of the connecting rod drive assembly 82 is first changed so that the extension direction of the connecting rod drive assembly 82 is basically toward the rear and lower part of the two-wheeled vehicle 100. The action direction of the connecting rod drive assembly 82 is further limited by the limiting guide rail 81, so that most of the pressure applied by the driver on the pedal 84 can be borne by the limiting guide rail 81. Through the above settings, since the limiting guide rail 81 bears most of the pressure, the loss of the connecting rod drive assembly 82 can be reduced, and the limiting guide rail 81 has a lower cost than the connecting rod drive assembly 82, which reduces the maintenance cost of the vehicle.

[0093] like Fig.12 As shown, as an implementation method, the pedal link assembly 83 includes a first pedal link 831, a second pedal link 832 and a third pedal link 833 connected in sequence, wherein the first pedal link 831 and the third pedal link 833 are each movably connected to the frame 10 at one end away from the second pedal link 832.

[0094] Specifically, the connection point between the first pedal link 831 and the second pedal link 832 is defined as a first node, the push rod structure 85 is connected to the first node, the connection point between the second pedal link 832 and the third pedal link 833 is defined as a second node, and the pedal 84 is arranged at the second node.

[0095] Exemplarily, when the foot pedal 84 is in the first fixed position, the foot pedal link assembly 83 folds into a "Z"-shaped structure, which lowers the height of the foot pedal 84 from the ground. At the same time, the foot pedal link assembly 83, which is composed of the first foot pedal link 831, the second foot pedal link 832 and the third foot pedal link 833 connected in sequence, is more compact, so that the foot pedal 84 has a height adjustment function without occupying the layout space of other components, thereby improving the rationality of the overall vehicle layout.

[0096] like Fig.13 As shown, when the foot pedal 84 is in the second fixed position, the extension directions of the first foot pedal link 831 and the second foot pedal link 832 are substantially coincident, thereby increasing the adjustment range of the foot pedal 84 in the smallest possible space.

[0097] As an implementation, the extension direction of the push rod structure 85 is defined as the push rod extension direction, and when the foot pedal 84 is in the second fixed position, the angle between the push rod extension direction and the height direction of the two-wheeled vehicle 100 is greater than or equal to 8° and less than or equal to 12°. Further, the angle between the push rod extension direction and the height direction of the two-wheeled vehicle 100 is greater than or equal to 9° and less than or equal to 11°. More preferably, the angle between the push rod extension direction and the height direction of the two-wheeled vehicle 100 is equal to 10°. It should be noted that, since the limiting guide rail 81 extends in a set direction, wherein the set direction is toward the rear and lower part of the two-wheeled vehicle 100, when the pedal 84 is in the second fixed position, the extension direction of the push rod is substantially perpendicular to the set direction, and the pedal 84 is subjected to downward pressure, and the common node of the first pedal link 831 and the second pedal link 832 is subjected to an upward thrust. Regardless of whether the angle between the extension direction of the push rod and the height direction of the two-wheeled vehicle 100 is too large or too small, the limiting guide rail 81 may be subjected to uneven force, resulting in the pedal 84 shaking. Through the above arrangement, the connecting rod drive assembly 82 can be kept in a state of maximum stroke to achieve the positioning of the pedal 84.

[0098] As an implementation method, the connecting rod drive assembly 82 includes a motor 821 and a screw rod 822 extending along a set direction. The motor 821 is installed on the frame 10. The motor 821 acts on the pedal connecting rod assembly 83 through the screw rod 822 to drive the pedal 84 to adjust between the first fixed position and the second fixed position.

[0099] In the example of the present application, the two-wheeled vehicle 100 further includes a vehicle body controller 60 that is the same as that in the first embodiment of the step device 80 and is used to control the height of the step device 80 and / or the steering device from the ground.

[0100] And the control unit 70, the control unit 70 can be a button or a display screen with a touch function, and the form of the control unit 70 is not specifically limited. In the example of the present application, the driver's touch operation on the control unit 70 can generate an adjustment instruction, and the body controller 60 obtains and identifies the adjustment instruction, generates a corresponding control signal according to the adjustment instruction, and then controls the connecting rod driving component 82 and / or the lifting driving component 44.

[0101] For example, the vehicle body controller 60 can independently control the connecting rod driving assembly 82 or the lifting driving assembly 44 in response to the driver's touch operation on the control unit 70. That is, when the height of the foot pedal 84 from the ground remains unchanged, the steering handle 43 is controlled to be raised or lowered, and vice versa.

[0102] In other examples, the vehicle body controller 60 can store the working positions of the foot pedal 84 and the steering handle 43 preset by the driver, wherein the working position can be at least one, in which the height of the foot pedal 84 from the ground is different, or the height of the steering handle 43 from the ground is different, or the spacing between the foot pedal 84 and the steering handle 43 along the length direction of the two-wheeled vehicle 100 is different. The vehicle body controller 60 can select one working position from the multiple working positions in response to the driver's touch operation on the control unit 70.

[0103] In other examples, the body controller 60 can generate a corresponding control signal in response to the driver's touch operation on the control unit 70, and simultaneously send the control signal to the connecting rod drive assembly 82 and the lifting drive assembly 44, so as to adjust the foot pedal 84 and the steering handle 43 in a linked manner. In the description of the present application, it should be understood that the term "length direction" refers to the front-to-back direction of the vehicle parallel to the driver of the two-wheeled vehicle in the driving state, the term "width direction" refers to the left-right direction of the vehicle parallel to the driver of the two-wheeled vehicle in the driving state, and the term "height direction" refers to the up-down direction of the vehicle parallel to the driver of the two-wheeled vehicle in the driving state.

[0104] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
