[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] See Figure 1 This application provides a motorcycle steering handlebar human-machine experimental platform, including a base 1; a lateral movement component 2, slidably connected to the base 1, which can perform high-precision lateral displacement on the base 1; a front reach arm rotating seat 3, slidably connected to the lateral movement component 2; a vertical drive component 4, disposed on the lateral movement component 2, for driving the front reach arm rotating seat 3 to perform high-precision vertical displacement; a front reach arm 5, rotatably mounted on the front reach arm rotating seat 3; an angle adjustment component, disposed on the front reach arm rotating seat 3, for adjusting and locking the angle of the front reach arm 5; a steering handlebar assembly 6, connected to the tail end of the front reach arm 5; and a test seat 7, disposed on the base 1.

[0043] In other words, base 1 ensures that the platform as a whole will not shake or shift due to external forces during the experiment.

[0044] The lateral movement component 2 is slidably connected to the base 1, enabling the lateral movement component 2 to perform high-precision displacement in the lateral direction (i.e., the X direction) on the base 1, in order to meet the requirements for precise adjustment of the lateral position of the steering handle in different experimental scenarios; the front extension arm rotating seat 3 is slidably connected to the lateral movement component 2, ensuring that it can move vertically (i.e., the Z direction) on the lateral movement component 2. In addition, the front extension arm rotating seat 3 enables the front extension arm 5 mounted on it to rotate, in order to simulate the use of the motorcycle steering handle at different angles.

[0045] The vertical drive assembly 4 is mounted on the lateral movement assembly 2 and connected to the reacharm rotating seat 3. Its function is to drive the reacharm rotating seat 3 to make high-precision vertical displacement, thereby adjusting the height position of the steering handle assembly 6.

[0046] The reach arm 5 is rotatably mounted on the reach arm rotating seat 3, enabling multi-angle and multi-directional adjustment of the steering handle assembly 6. The angle adjustment component is located on the reach arm rotating seat 3 and connected to the reach arm 5. It is used to adjust and lock the angle of the reach arm 5, thereby controlling the angle position of the steering handle assembly 6. The steering handle assembly 6 is connected to the tail end of the reach arm 5. The steering handle assembly 6 can simulate the steering operation of a motorcycle during actual driving. Experimenters can operate the steering handle assembly 6 to experience the steering feel under different parameter settings.

[0047] The test seat 7 is set on the base 1, and its position can be adjusted according to the experimental needs. It can simulate the driver's sitting posture when riding a motorcycle and provide the testers with a real riding experience.

[0048] The motorcycle handlebar human-machine experimental platform provided in this application has the following beneficial effects:

[0049] This experimental platform possesses high-precision lateral and vertical displacement adjustment capabilities, as well as adjustments for the reach arm angle and the rotation of the handlebar assembly 6. This enables multi-dimensional adjustments to the handlebar assembly 6 in lateral, vertical, angular, and rotational directions, allowing for precise simulation of motorcycle handlebar usage scenarios at different positions and angles. This meets diverse experimental needs, improves the efficiency of motorcycle driving posture simulation research, and reduces development costs. For example, when studying the comfort requirements of drivers of different heights for handlebar height and angle, precise adjustments to the height and angle of the handlebar assembly 6 provide strong support for motorcycle ergonomic design, thereby improving the comfort and usability of motorcycle products and enhancing market competitiveness.

[0050] Based on the above embodiments, see Figure 2 The lateral movement component 2 includes linear guide rails 21, two of which are parallel and spaced apart on the base 1; a sliding support 22, the bottom of which is provided with a slider 23 that matches the linear guide rails 21; and a lateral drive unit, which is connected to the sliding support 22 and is used to control the lateral displacement of the sliding support 22. The lateral drive unit includes: a first motor 24, which is installed in a receiving groove provided on the base 1, the receiving groove being located between the two parallel linear guide rails 21, and the output end of the first motor 24 is connected to a first lead screw 25; and a first nut sleeve 26, the bottom of which is provided with a first nut sleeve 26 that matches the first lead screw 25.

[0051] Specifically, two linear guide rails 21 are arranged parallel and spaced apart on the base 1. The linear guide rails 21 have high hardness and low surface roughness, which can effectively reduce the wear of the slider 23 during the sliding process and extend the service life of the guide rails.

[0052] The bottom of the sliding support 22 is provided with a slider 23 that matches the linear guide rail 21, so that the sliding support 22 can slide smoothly on the linear guide rail 21.

[0053] The first motor 24 is a servo motor, which is installed in the receiving groove on the base 1. The receiving groove is located between two parallel linear guide rails 21, which facilitates the installation of the motor. The servo motor has the advantages of fast response speed, high control accuracy and good torque characteristics. It can accurately adjust the speed and direction according to the input control signal. The output end of the first motor 24 is connected to the first lead screw 25. The bottom of the sliding bearing seat 22 is provided with a first nut sleeve 26 that is adapted to the first lead screw 25. When the first lead screw 25 rotates, the first nut sleeve 26 can drive the sliding bearing seat 22 to move linearly.

[0054] In actual operation, a control signal is first sent to the first motor 24. The first motor 24 rotates according to the signal command, which drives the first lead screw 25 to rotate. The rotation of the first lead screw 25 is converted into the lateral linear motion of the sliding bearing seat 22 through the first nut sleeve 26, thereby realizing the precise adjustment of the steering handle assembly in the lateral direction.

[0055] Based on the above embodiments, see Figure 2 The upper surface of the sliding support 22 is provided with upright plates on both sides. The upper surfaces of the two upright plates are connected to the support plate 27. Guide posts 28 are fixed at the four corners of the upper surface of the support plate 27. The forward arm rotating seat 3 includes a base plate 31 and a hinge seat 32 provided on the base plate 31. The four corners of the base plate 31 are provided with guide holes 33 that cooperate with the guide posts 28. The vertical drive assembly 4 includes a second motor 41, which is fixedly installed at the bottom of the support plate 27; a second lead screw 42, which is rotatably set in the middle of the support plate 27 and is connected to the output end of the second motor 41; and a second nut sleeve, which is embedded in the middle of the base plate 31 and threadedly connected to the second lead screw 42.

[0056] Specifically, upright plates are provided on both sides of the upper end face of the sliding bearing seat 22. Specifically, the upright plates on both sides are perpendicular to the upper end face of the sliding bearing seat 22, thereby providing stable support for the support plate 27.

[0057] Guide posts 28 are fixed at the four corners of the upper end face of the support plate 27 to ensure that the axes of the four guide posts 28 are parallel to each other and perpendicular to the upper end face of the support plate 27, thereby providing guidance for the vertical movement of the forward arm rotating seat 3.

[0058] The forward extension arm rotating seat 3 includes a base plate 31 and a hinge seat 32 provided on the base plate 31. The four corners of the base plate 31 are provided with guide holes 33 that cooperate with the guide post 28. The inner diameter of the guide hole 33 is adapted to the outer diameter of the guide post 28 to ensure that the base plate 31 can move smoothly vertically on the guide post 28, while effectively limiting its horizontal displacement, thus ensuring the accuracy and stability of the movement.

[0059] The second motor 41 is a servo motor, which is fixedly installed at the bottom of the support plate 27. The second lead screw 42 is rotatably set in the middle of the support plate 27. One end of the second lead screw 42 is connected to the output end of the second motor 41 through a coupling and is fixed on the support plate 27 through a bearing seat.

[0060] The second nut sleeve is fitted into the middle of the base plate 31 and threadedly connected to the other end of the second lead screw 42. When the second lead screw 42 rotates, the second nut sleeve can accurately convert the rotational motion of the second lead screw 42 into the vertical linear motion of the base plate 31.

[0061] In actual operation, a control signal can be sent to the second motor 41. The second motor 41 rotates according to the signal command, driving the second lead screw 42 to rotate through the coupling. The rotation of the second lead screw 42 is converted into the vertical linear motion of the base plate 31 through the second nut sleeve. Since the base plate 31 is engaged with the guide post 28 through the guide hole 33, the base plate 31 can only make precise vertical movements along the guide post 28, thereby driving the forward arm rotating seat 3 and the forward arm to achieve precise vertical position adjustment.

[0062] The vertical drive assembly 4 of this application also provides another embodiment. The vertical drive assembly 4 is an electric push rod. The fixed end of the electric push rod is installed on the upper end surface of the support plate 27, and the output end of the electric push rod is set on the lower surface of the base plate 31. When the motor rotates forward, the push rod extends upward and pushes the base plate 31 to move upward. When the motor rotates in reverse, the push rod retracts downward and drives the base plate 31 to move downward, thereby realizing the control of the vertical displacement of the base plate 31.

[0063] Based on the above embodiments, see Figure 2 , Figure 3 The hinge seat 32 has symmetrical ear plates on one side, and the hinge seat 32 located between the two ear plates has a notch 34. The extension arm 5 is rotatably connected to the two ear plates through a pin, and the bottom end of the extension arm 5 is located in the notch 34.

[0064] Specifically, the hinge seat 32 has symmetrical ear plates on one side. On the ear plates, there are pin holes. The diameter of the pin holes is matched with the outer diameter of the pin to ensure that the pin can be tightly installed in the ear plates, reduce the gap and shaking during rotation, and improve the smoothness of the rotation of the forward extension arm 5. The forward extension arm 5 is rotatably connected to the two ear plates through the pin.

[0065] The hinge seat 32 located between the two ear plates has a notch 34. The notch 34 is rectangular in shape, and its size is precisely designed according to the shape and size of the bottom end of the extension arm 5 to ensure that the bottom end of the extension arm 5 can be precisely inserted into the notch 34.

[0066] When installing the extendable arm 5, first accurately insert the bottom end of the extendable arm 5 into the notch 34 of the hinge seat 32, ensuring that the axis of the extendable arm 5 is aligned with the design axis of the hinge seat 32. Then, pass the pin through the pin holes of the two ear plates and the corresponding holes on the extendable arm 5 to connect the extendable arm 5 to the ear plates. To prevent the pin from falling off during use, cotter pins can be installed at both ends of the pin.

[0067] Based on the above embodiments, the angle adjustment assembly includes an angle adjustment bolt 8 and a fixing bolt 9. The hinge seat 32 is provided with an angle adjustment hole 81 and a first fixing hole 91 on the side away from the ear plate, and the bottom end of the extension arm 5 is provided with a second fixing hole 92 corresponding to the first fixing hole 91.

[0068] In other words, when it is necessary to adjust the angle of the reach arm 5, the angle adjusting bolt 8 is rotated to screw it into or out of the angle adjusting hole 81. As the depth of screwing in the angle adjusting bolt 8 changes, the bottom end of the reach arm 5 is pushed to move within the notch 34, thereby changing the rotation angle of the reach arm 5 relative to the hinge seat 32. Since the position and thread specification of the angle adjusting hole 81 are fixed, the angle of the reach arm 5 can be precisely adjusted by precisely controlling the amount of screwing in the angle adjusting bolt 8.

[0069] After the angle adjustment is completed, pass the fixing bolt 9 through the first fixing hole 91 and the second fixing hole 92 and tighten it. At this time, the preload generated by the fixing bolt 9 will press the extension arm 5 tightly into the notch 34 of the hinge seat 32, restricting the rotation of the extension arm 5 and fixing it in the required angle position, ensuring that the extension arm 5 will not move unexpectedly during the experiment, and ensuring the accuracy and stability of the experiment.

[0070] Based on the above embodiments, the steering handle assembly 6 is rotatably connected to the top end of the reach arm 5 via the steering shaft 61, and a locking bolt 62 is provided between the steering handle assembly 6 and the reach arm 5.

[0071] Specifically, when conducting an experiment requiring the steering handle assembly 6 to rotate flexibly, first loosen the locking bolt 62. After the steering handle assembly 6 is rotated to the desired angle position, a locking operation is required to fix its position. At this time, use a wrench to gradually tighten the locking bolt 62 in a diagonal sequence.

[0072] Based on the above embodiments, both ends of the reach arm 5 are provided with angle markings 51. Specifically, the angle markings 51 at the front end of the reach arm 5 are mainly used to measure the rotation angle of the reach arm 5 relative to the reach arm rotating seat 3, which can help the experimenter to intuitively understand the deflection of the reach arm 5 during steering operation, while the angle markings 51 at the rear end focus on measuring the rotation angle of the reach arm 5.

[0073] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0074] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
