[0036] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0037] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0038] The speed control mechanism 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0039] like Figures 1-6 As shown, the speed control mechanism 1 according to an embodiment of the present utility model includes a controller 100, a flexible shaft mechanism 200, and a guide bracket 300.

[0040] The control unit 100 is mounted on the cab floor 10 and extends upward through the cab floor 10. The flexible shaft mechanism 200 includes a gear selection flexible shaft 210 and a gear shift flexible shaft 220. One end of the gear selection flexible shaft 210 and the gear shift flexible shaft 220 is connected to the control unit 100. The gear selection flexible shaft 210 and the gear shift flexible shaft 220 extend rearwards from the control unit 100 and coil around the powertrain 20. The other end of the gear selection flexible shaft 210 and the gear shift flexible shaft 220 is connected to the powertrain 20. A guide bracket 300 is fixed to the front side of the powertrain 20, and the guide bracket 300 secures the gear shift flexible shaft 210 and the gear selection flexible shaft 220 by clamps.

[0041] For example, during the assembly process, the transmission control mechanism 1 can first be passed through the cab floor 10 and bolted to the cab floor 10. Then, the flexible shaft clamps can be respectively attached to the color marks of the gear selection flexible shaft 210 and the shift flexible shaft 220, and the gear selection flexible shaft 210 and the shift flexible shaft 220 can be fixed to the powertrain 20 with bolts. During the vehicle rollover process, the end of the flexible shaft mechanism 200 near the controller 100 will be continuously lifted, and the position of the guide bracket 300 remains unchanged. Since the flexible shaft mechanism 200 is deformable, after the vehicle rollover reaches the maximum rollover amount, the end of the flexible shaft mechanism 200 near the controller 100 and the guide bracket 300 are in an extended state and are not taut.

[0042] According to the speed change control mechanism 1, the shift soft shaft 210 and the gear shift soft shaft 220 extend to the rear of the controller 100 and coil around the top of the power assembly 20, which helps to reduce the space occupation of the soft shaft mechanism 200 and ensure the compact layout of the power assembly 20 and other components. The guide bracket 300 is fixed to the front side of the power assembly 20 and fixes the gear shift soft shaft 210 and the shift soft shaft 210 through the clamp, which can ensure the stability and reliability of the soft shaft mechanism 200. The guide bracket 300 helps to guide and fix the movement direction of the soft shaft mechanism 200 and ensures that the soft shaft mechanism 200 does not deviate from the track during the operation process, thereby ensuring the normal operation and stability of the speed change control mechanism 1. When the vehicle body is overturned forward, due to the fixing effect of the guide bracket 300, the length of the soft shaft mechanism 200 is fixed, and the soft shaft mechanism 200 adjacent to one end of the controller 100 will deform when the vehicle body is overturned, which ensures the maximum overturning amount of the vehicle body and does not cause damage to the soft shaft mechanism 200.

[0043] In addition, the shift soft shaft 210 and the gear shift soft shaft 220 extend to the rear of the controller 100 and the power assembly 20, and the connection mode makes the soft shaft mechanism 200 more smooth, reduces the bending angle and bending radius, and helps to reduce the stress concentration generated in the bending process of the soft shaft mechanism 200, thereby improving the reliability and stability of the soft shaft mechanism 200.

[0044] Therefore, the speed change control mechanism 1 has the advantages of satisfying the maximum overturning amount of the vehicle body and ensuring the bending radius.

[0045] In some specific embodiments of the utility model, as shown in the drawings, Figure 4 The guide bracket 300 includes a vertical plate part 310 and a top plate part 320, the vertical plate part 310 extends to the top of the power assembly 20, the top plate part 320 is connected to the vertical plate part 310 and extends to the horizontal direction, and the gear shift soft shaft 220 and the shift soft shaft 210 are installed on the top plate part 320.

[0046] The vertical plate part 310 extends to the top of the power assembly 20 and provides vertical support for the guide bracket 300, which can enhance the stability and overall rigidity of the guide bracket 300. The top plate part 320 is connected to the vertical plate part 310 and extends to the horizontal direction, so that the structure of the entire guide bracket 300 is more solid, which can effectively support the movement of the gear shift soft shaft 220 and the shift soft shaft 210 and keep them in the correct position.

[0047] At the same time, the top plate part 320 serves as the installation platform of the gear shift soft shaft 220 and the shift soft shaft 210 and provides stable support and guidance, which ensures the stability of the soft shaft mechanism 200 far from the controller 100 during the operation process and improves the reliability and safety of the speed change control mechanism 1.

[0048] In some embodiments of the present application, as shown in Figure 3 and Figure 5 , the variable speed control mechanism 1 further comprises a first soft shaft support 400. The first soft shaft support 400 is adapted to be mounted on the longitudinal beam 30, and the selection soft shaft 210 and the shift soft shaft 220 are both mounted on the first soft shaft support 400. The first soft shaft support 400 is mounted on the longitudinal beam 30 of the vehicle, providing a stable support point for the selection soft shaft 210 and the shift soft shaft 220, ensuring that the soft shaft mechanism 200 maintains the correct installation position during vehicle operation, avoiding misplacement or damage of the soft shaft mechanism 200 due to vibration or movement, and ensuring the accuracy and reliability of the variable speed control mechanism 1. At the same time, by integrating the soft shaft mechanism 200 on the first soft shaft support 400, the wiring and pipeline layout of the vehicle bottom can be optimized, avoiding interference between the soft shaft mechanism 200 and other components, especially in the limited space of the vehicle interior, making rational use of space, making maintenance and inspection more convenient.

[0049] In some embodiments of the present application, as shown in Figure 5 , the first soft shaft support 400 comprises a mounting arm 410 and a mounting block 420. The mounting arm 410 is adapted to be mounted on the longitudinal beam 30. The shift soft shaft 210 and the selection soft shaft 220 are arranged through the mounting block 420 and fixed by the mounting block 420. The mounting block 420 is provided with a mounting hole in the middle, and the shift soft shaft 210 and the selection soft shaft 220 are respectively arranged through the mounting hole and fixed on the first soft shaft support 400. The fasteners are sequentially arranged through the top of the mounting block 420 and the mounting arm 410 and fixedly connected with the longitudinal beam 30.

[0050] Overall, the mounting arm 410 is mounted on the longitudinal beam 30, and the mounting arm 410 provides a stable support platform, which can effectively fix the position of the first soft shaft support 400, ensuring that the soft shaft mechanism 200 does not shake or loosen during operation, maintaining its stability and reliability. The mounting block 420 is a component through which the shift soft shaft 210 and the selection soft shaft 220 are arranged and fixed, and the position of the soft shaft mechanism 200 is fixed by the mounting block 420, ensuring that the soft shaft mechanism 200 does not displace or deviate during transmission, ensuring the normal working state of the soft shaft mechanism 200, avoiding transmission failure or damage.

[0051] In some embodiments of the present application, as shown in Figure 5 , the mounting block 420 comprises a lower mounting block 421 and an upper mounting block 422. The lower mounting block 421 is mounted on the mounting arm 410. The upper mounting block 422 is fixed with the lower mounting block 421 by arranging fasteners, and the shift soft shaft 220 and the selection soft shaft 210 are clamped by the upper mounting block 422 and the lower mounting block 421.

[0052] By matching the upper mounting block 422 and the lower mounting block 421, the shift soft shaft 220 and the selection soft shaft 210 can be firmly clamped, so that the soft shaft mechanism 200 can be kept stable under any driving condition, displacement caused by vibration or external force is avoided, and the accuracy and reliability of the gear shift operating mechanism 1 are ensured.

[0053] In some embodiments of the utility model, as shown in Figure 6 The gear shift operating mechanism 1 further comprises a second soft shaft support 500. The second soft shaft support 500 is installed on the power assembly 20, and the second soft shaft support 500 comprises an upper wing plate 510 and a side wing plate 520. The selection soft shaft 210 is installed on the upper wing plate 510 through a pipe clamp, and the shift soft shaft 220 is installed on the side wing plate 520 through a pipe clamp. The side of the second soft shaft support 500 connecting the upper wing plate 510 and the side wing plate 520 is fixedly connected with the power assembly 20 through fasteners. The second soft shaft support 500 serves as a mounting support of the soft shaft mechanism 200. By being installed on the power assembly 20, the second soft shaft support 500 provides fixed support for the shift soft shaft 220 and the selection soft shaft 210. By being installed on the upper wing plate 510 and the side wing plate 520 through pipe clamps, the second soft shaft support 500 ensures that the soft shaft mechanism 200 keeps a stable position during operation, reduces shaking and friction of the soft shaft mechanism 200 during transmission, and improves the working efficiency and reliability of the gear shift operating mechanism 1.

[0054] In some embodiments of the utility model, as shown in Figure 1 And Figure 3 The shift soft shaft 220 and the selection soft shaft 210 are bent and extended rearward and downward of the manipulator 100. The bending radius of the shift soft shaft 220 and the selection soft shaft 210 is not less than 250 mm.

[0055] The shift soft shaft 220 and the selection soft shaft 210 are bent and extended rearward and downward, which makes full use of the space in the longitudinal and vertical directions of the vehicle, avoids the shift soft shaft 220 and the selection soft shaft 210 directly passing through the complex pipelines and lines under the cab floor 10, and helps to optimize the space layout of the cab, leaving more space for other systems and components. By setting the bending radius to be not less than 250 mm, stress concentration of the soft shaft mechanism 200 at the bending position can be effectively reduced, material fatigue and wear caused by excessive bending are avoided, the service life of the soft shaft mechanism 200 is prolonged, the maintenance and replacement frequency is reduced, and the overall operation efficiency of the vehicle is improved.

[0056] In some embodiments of the utility model, as shown in Figure 1As shown, the manipulator 100 comprises a manipulator handle 110 and a base 120. The manipulator handle 110 is adapted to pass through the cab floor 10. The base 120 is mounted to the cab floor 10, and the base 120 is configured with a soft shaft passage extending rearward, and the selection soft shaft 210 and the shift soft shaft 220 are arranged in the soft shaft passage.

[0057] By mounting the base 120 to the cab floor 10 and passing the manipulator handle 110 through the cab floor 10, the stability of the manipulator 100 is achieved, which can ensure that the manipulator 100 does not sway or shift during driving, and the stability and reliability of the operation are improved. At the same time, the structure that the soft shaft passage extends rearward optimizes the layout of the selection soft shaft 210 and the shift soft shaft 220, fully utilizes the longitudinal space of the vehicle, avoids the interference between the selection soft shaft 210 and the shift soft shaft 220 and other components in the cab, saves the space in the vehicle, and helps to improve the spaciousness and comfort of the cab.
