[0051] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0053] Engineering vehicles typically include a dual-pedal mechanism, such as forklifts. The dual-pedal mechanism of a forklift includes a left pedal and a right pedal. The driver can drive the forklift to perform corresponding actions by pressing the left pedal or the right pedal.

[0054] However, the existing dual-pedal mechanism of forklifts is linked to the left and right pedals. When the driver presses the left pedal, the right pedal is lifted, and when the driver presses the right pedal, the left pedal is lifted, which affects the driver's driving experience.

[0055] The dual-pedal mechanism and engineering vehicle provided in this application, when the driver presses the first pedal, the first linkage structure realizes the linkage between the first drive block and the gear set, so that the rotation of the first drive block can synchronously drive the gear set. The second linkage structure disengages the linkage between the second drive block and the gear set, so that the gear set driven by the first drive block will not drive the second drive block to rotate relative to the second rotating shaft, thereby avoiding the second pedal from being raised due to the rotation of the second drive block. When the driver presses the second pedal, the second linkage structure realizes the linkage between the second drive block and the gear set, so that the rotation of the second drive block can synchronously drive the gear set. The first linkage structure disengages the linkage between the first drive block and the gear set, so that the gear set driven by the second drive block will not drive the first drive block to rotate relative to the first rotating shaft, thereby avoiding the second pedal from being raised due to the rotation of the first drive block, thus improving the driver's driving experience.

[0056] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0057] Firstly, see [the following] Figures 1-5As shown in the figure, this application embodiment provides a dual-pedal mechanism, which includes a mounting frame 100. A first rotating shaft 110 and a second rotating shaft 120 are disposed on the mounting frame 100. The positions of the first rotating shaft 110 and the second rotating shaft 120 are parallel to each other and spaced apart. A first driving block 200 is disposed on the first rotating shaft 110, and a second driving block 300 is disposed on the second rotating shaft 120. The first driving block 200 has a first through hole 210 passing through it, and the first driving block 200 is sleeved on the first rotating shaft 110 through the first through hole 210, and the first driving block 200 is rotatable relative to the first rotating shaft 110. The second driving block 300 has a second through hole 310 passing through it, and the second driving block 300 is sleeved on the second rotating shaft 120 through the second through hole 310, and the second driving block 300 is rotatable relative to the second rotating shaft 120. The first drive block 200 is connected to the first pedal 220, so that when the driver presses the first pedal 220, the first pedal 220 can drive the first drive block 200 to rotate relative to the first rotating shaft 110. The second drive block 300 is connected to the second pedal 320, so that when the driver presses the second pedal 320, the second pedal 320 can drive the second drive block 300 to rotate relative to the second rotating shaft 120. A first clamping plate 400 and a second clamping plate 500 are also provided at the mounting bracket 100. The positions of the first clamping plate 400 and the second clamping plate 500 are opposite to each other, and the first clamping plate 400 and the second clamping plate 500 can move closer to each other or further away from each other; that is, the first clamping plate 400 can move relative to the second clamping plate 500. The first clamping plate 400 and the second clamping plate 500 are located on both sides of the first drive block 200 and on both sides of the second drive block 300, respectively, so that the first clamping plate 400 and the second clamping plate 500 can form a... Clamping function: The first clamping plate 400 and the second clamping plate 500 tend to move closer to each other, thereby clamping the first driving block 200 and the second driving block 300. Since the first driving block 200 can rotate relative to the first rotating shaft 110 and the second driving block 300 can rotate relative to the second rotating shaft 120, the first driving block 200 and the second driving block 300 can remain parallel to each other under the clamping action of the first clamping plate 400 and the second clamping plate 500, thereby keeping the first pedal 220 and the second pedal 320 at the same height.

[0058] It should be noted that, see Figure 2 and Figure 5As shown, the first driving block 200 has a first sidewall 230 and a second sidewall 240 positioned opposite each other in the first direction X, wherein the first direction X is the direction in which the first clamping plate 400 and the second clamping plate 500 are arranged opposite each other; the second driving block 300 has a third sidewall 330 and a fourth sidewall 340 positioned opposite each other in the first direction X; when the first clamping plate 400 and the second clamping plate 500 clamp the first driving block 200 and the second driving block 300, the first clamping plate 400 respectively abuts against the first driving block 200. The first sidewall 230 and the third sidewall 330 of the second drive block 300, and the second clamping plate 500 respectively attach to the second sidewall 240 of the first drive block 200 and the fourth sidewall 340 of the second drive block 300, so that the first clamping plate 400 and the second clamping plate 500 can clamp the first drive block 200 and the second drive block 300, and keep the first drive block 200 and the second drive block 300 parallel to each other, so as to achieve the same height of the first pedal 220 and the second pedal 320.

[0059] See Figure 2 , Figure 6 and Figure 7 As shown, the dual-pedal mechanism of this embodiment further includes a gear set 600, which is connected to the first rotating shaft 110 and the second rotating shaft 120 respectively, and is rotatable relative to the first rotating shaft 110 and the second rotating shaft 120. A first linkage structure 700 is provided between the gear set 600 and the first driving block 200. The first linkage structure 700 enables linkage between the first driving block 200 and the gear set 600, and also enables disengagement of the linkage between the first driving block 200 and the gear set 600. A second linkage structure 800 is provided between the gear set 600 and the second driving block 300. The second linkage structure 800 enables linkage between the second driving block 300 and the gear set 600, and also enables disengagement of the linkage between the first driving block 200 and the gear set 600.

[0060] For example, when the driver presses the first pedal 220, the first pedal 220 can drive the first drive block 200 to rotate relative to the first rotating shaft 110. During this process, the first linkage structure 700 realizes the linkage between the first drive block 200 and the gear set 600, so that the rotation of the first drive block 200 can synchronously drive the gear set 600. The second linkage structure 800 releases the linkage between the second drive block 300 and the gear set 600, so that the gear set 600 driven by the first drive block 200 will not drive the second drive block 300 to rotate relative to the second rotating shaft 120, thereby avoiding the second pedal 320 from being raised due to the rotation of the second drive block 300. Correspondingly, when the driver presses the second pedal 320, the second pedal 320 can drive the second drive block 300 to rotate relative to the second rotating shaft 120. During this process, the second linkage structure 800 realizes the linkage between the second drive block 300 and the gear set 600, so that the rotation of the second drive block 300 can synchronously drive the gear set 600. Meanwhile, the first linkage structure 700 releases the linkage between the first drive block 200 and the gear set 600, thereby preventing the gear set 600 driven by the second drive block 300 from driving the first drive block 200 to rotate relative to the first rotating shaft 110, thus avoiding the second pedal 320 from being raised due to the rotation of the first drive block 200.

[0061] It is worth mentioning that the dual-pedal structure of this application embodiment, by setting a gear set 600 on the first rotating shaft 110 and the second rotating shaft 120, and setting a first linkage structure 700 and a second linkage structure 800 between the gear set 600 and the first drive block 200 and the second drive block 300 respectively, the first linkage structure 700 can realize the linkage and disengagement between the first drive block 200 and the gear set 600, and the second linkage structure 800 can realize the linkage and disengagement between the second drive block 300 and the gear set 600. Thus, when one of the first pedal 220 and the second pedal 320 is pressed, the other pedal 220 and the second pedal 320 will not be raised, which can improve the driver's driving experience.

[0062] In some implementations, see Figure 7 As shown, a plurality of connecting components 900 are provided on the first clamping plate 400 and the second clamping plate 500, and each connecting component 900 includes a bolt 910, a spring 920, a pressure plate 930 and a nut 940.

[0063] In this embodiment, a bolt 910 passes through a first clamping plate 400 and a second clamping plate 500. Exemplarily, the bolt 910 has a head end 911 and a threaded section 912. The threaded section 912 of the bolt 910 passes sequentially through the first clamping plate 400 and the second clamping plate 500, such that the head end 911 of the bolt 910 is located on the side of the first clamping plate 400 opposite to the second clamping plate 500, and the end of the threaded section 912 of the bolt 910 away from the head end 911 is located on the side of the second clamping plate 500 opposite to the first clamping plate 400. A nut 940 is located on the side of the second clamping plate 500 opposite to the first clamping plate 400, and the nut 940 is threaded onto the threaded section 912 of the bolt 910. A pressure plate 930 is located on the side of the second clamping plate 500 opposite to the first clamping plate 400, and the pressure plate 930 is sleeved on the threaded section 912 of the bolt 910, and the pressure plate 930 is located between the second clamping plate 500 and the nut 940. Spring 920 is located on the side of the second clamping plate 500 away from the first clamping plate 400, and spring 920 is sleeved on the threaded section 912 of bolt 910. Spring 920 is located between the second clamping plate 500 and the pressure plate 930 and abuts against the second clamping plate 500 and the pressure plate 930 respectively.

[0064] When the driver presses down on the first pedal 220, the first drive block 200 presses down on the first clamping plate 400 and the second clamping plate 500, causing the second clamping plate 500 to compress the spring 920 and move away from the head end 911 of the bolt 910 on the threaded section 912. This causes the first clamping plate 400 and the second clamping plate 500 to move away from each other, allowing the first drive block 200 to rotate relative to the first rotating shaft 110, so that the first drive block 200 and the second drive block 300 are no longer parallel. When the driver removes his foot from the first pedal 220, the spring 920 presses down on the second clamping plate 500, causing the first clamping plate 400 and the second clamping plate 500 to move closer together. This causes the first clamping plate 400 and the second clamping plate 500 to push the first drive block 200 to rotate in the opposite direction, so that the first drive block 200 and the second drive block 300 return to a parallel state, and the first pedal 220 and the second pedal 320 return to the same height. Correspondingly, when the driver presses down on the second pedal 320, the second drive block 300 presses against the first clamping plate 400 and the second clamping plate 500 respectively, causing the second clamping plate 500 to compress the spring 920 and move on the threaded section 912 of the bolt 910 in a direction away from the head end 911 of the bolt 910. This causes the first clamping plate 400 and the second clamping plate 500 to move away from each other, allowing the second drive block 300 to rotate relative to the second rotating shaft 120, so that the second drive block 300 and the first drive block 200 are no longer parallel. When the driver removes his foot from the second pedal 320, the spring 920 presses against the second clamping plate 500, causing the first clamping plate 400 and the second clamping plate 500 to move closer to each other. This causes the first clamping plate 400 and the second clamping plate 500 to push the second drive block 300 to rotate in the opposite direction, so that the first drive block 200 and the second drive block 300 return to a parallel state, and the first pedal 220 and the second pedal 320 return to the same height.

[0065] In some implementations, see Figure 6 As shown, the first linkage structure 700 includes a first locking block 710 and a first locking slot 720. The first locking block 710 has a first end and a second end positioned opposite each other. The first end of the first locking block 710 is rotatably connected to the first drive block 200, and the second end of the first locking block 710 extends toward the gear set 600. The first locking slot 720 is disposed on the gear set 600, and the first locking slot 720 is used for the second end of the first locking block 710 to extend into, so that the first locking block 710 can be locked into the first locking slot 720.

[0066] In this embodiment, when the driver presses the first pedal 220, the second end of the first locking block 710 is located in the first locking groove 720, so that the second end of the first locking block 710 is engaged in the first locking groove 720. Thus, under the engaging action of the first locking block 710 and the second locking groove 720, the first driving block 200 and the gear set 600 can be linked, allowing the rotation of the first driving block 200 relative to the first rotating shaft 110 to synchronously drive the gear set 600. When the driver presses the second pedal 320, the first linkage structure 700 disengages the linkage between the first driving block 200 and the gear set 600. During this process, the second end of the first locking block 710 is at least partially moved out of the first locking groove 720, and the gear set 600 driven by the second driving block 300 will not cause the first driving block 200 to rotate relative to the first rotating shaft 110, thereby preventing the first pedal 220 from being raised.

[0067] In some implementations, see Figure 6 As shown, the first linkage structure 700 also includes a first elastic element 730, wherein the first elastic element 730 has a first end and a second end that are positioned opposite each other. The first end of the first elastic element 730 is connected to the first drive block 200, and the second end of the first elastic element 730 is connected to the second end of the first locking block 710. The first elastic element 730 is used to push the second end of the first locking block 710 to move toward the gear set 600 by the rotation of the first end of the first locking block 710 on the first drive block 200.

[0068] For example, when the driver presses the first pedal 220, the first elastic element 730 can push the first locking block 710, so that the second end of the first locking block 710 can be located in the first locking groove 720 and engage with the first locking groove 720, thereby realizing the linkage between the first driving block 200 and the gear set 600, so that the rotation of the first driving block 200 relative to the first rotating shaft 110 can synchronously drive the gear set 600. When the driver presses the second pedal 320, the second pedal 320 causes the second drive block 300 to rotate relative to the second rotating shaft 120. The second drive block 300 then drives the gear set 600. When the gear set 600 is driven by the second drive block 300, the gear set 600 can push the second end of the first locking block 710, so that the second end of the first locking block 710 is at least partially moved out of the first locking slot 720 by compressing the first elastic member 730. The gear set 600 driven by the second drive block 300 will not cause the first drive block 200 to rotate relative to the first rotating shaft 110, thereby preventing the first pedal 220 from being raised.

[0069] It is understood that the first elastic element 730 includes, but is not limited to, components with elastic properties such as springs or rubber.

[0070] In some implementations, see Figure 6As shown, the second linkage structure 800 includes a second locking block 810 and a second locking slot 820. The second locking block 810 has a first end and a second end that are positioned opposite each other. The first end of the second locking block 810 is rotatably connected to the second drive block 300, and the second end of the second locking block 810 extends toward the gear set 600. The second locking slot 820 is disposed on the gear set 600, and the second locking slot 820 is used to allow the second end of the second locking block 810 to extend into it, so that the second locking block 810 can be locked into the second locking slot 820.

[0071] In this embodiment, when the driver presses the second pedal 320, the second end of the second locking block 810 is located in the second locking slot 820, so that the second end of the second locking block 810 is engaged in the second locking slot 820. Thus, under the engaging action of the second locking block 810 and the second locking slot 820, the second driving block 300 and the gear set 600 can be linked, allowing the rotation of the second driving block 300 relative to the second rotating shaft 120 to synchronously drive the gear set 600. When the driver presses the first pedal 220, the second linkage structure 800 disengages the linkage between the second driving block 300 and the gear set 600. During this process, the second end of the second locking block 810 is at least partially moved out of the second locking slot 820, and the gear set 600 driven by the first driving block 200 will not cause the second driving block 300 to rotate relative to the second rotating shaft 120, thereby preventing the second pedal 320 from being raised.

[0072] In some implementations, see Figure 6 As shown, the second linkage structure 800 also includes a second elastic member 830, wherein the second elastic member 830 has a first end and a second end that are positioned opposite each other. The first end of the second elastic member 830 is connected to the second drive block 300, and the second end of the second elastic member 830 is connected to the second end of the second locking block 810. The second elastic member 830 is used to push the second end of the second locking block 810 to move toward the gear set 600 by the rotation of the first end of the second locking block 810 on the second drive block 300.

[0073] For example, when the driver presses the second pedal 320, the second elastic element 830 can push the second locking block 810, so that the second end of the second locking block 810 can be located in the second locking groove 820 and engage with the second locking groove 820, thereby realizing the linkage between the second driving block 300 and the gear set 600, so that the rotation of the second driving block 300 relative to the second rotating shaft 120 can synchronously drive the gear set 600. When the driver presses the first pedal 220, the first pedal 220 causes the first drive block 200 to rotate relative to the first rotating shaft 110. The first drive block 200 then drives the gear set 600. When the gear set 600 is driven by the first drive block 200, the gear set 600 can push the second end of the second locking block 810, so that the second end of the second locking block 810 is at least partially moved out of the second locking slot 820 by compressing the second elastic member 830. The gear set 600 driven by the first drive block 200 will not cause the second drive block 300 to rotate relative to the second rotating shaft 120, thereby preventing the second pedal 320 from being raised.

[0074] It is understood that the second elastic element 830 includes, but is not limited to, components with elastic properties such as springs or rubber.

[0075] In some implementations, see Figure 2 and Figure 7 As shown, the gear set 600 includes at least a first gear 610 and a second gear 620. The first gear 610 is sleeved on the first rotating shaft 110 and can rotate relative to the first rotating shaft 110. The second gear 620 is sleeved on the second rotating shaft 120 and can rotate relative to the second rotating shaft 120. The first gear 610 and the second gear 620 are linked together.

[0076] It is understandable that the linkage between the first gear 610 and the second gear 620 can be achieved by the first gear 610 and the second gear 620 directly driving each other, or by the first gear 610 and the second gear 620 indirectly achieving linkage through another connecting part, without any particular limitation.

[0077] In the embodiments of this application, see Figure 6As shown, the first slot 720 is disposed on the first gear 610 of the gear set 600, and the second slot 820 is disposed on the second gear 620 of the gear set 600. When the first pedal 220 is pressed, it drives the first drive block 200 to rotate in the forward direction. Since the first locking block 710 is engaged in the first locking slot 720, the first drive block 200 and the first gear 610 remain stationary relative to each other. The first gear 610 rotates in the forward direction with the first drive block 200. During this process, the first gear 610 drives the second gear 620 to rotate in the forward direction. The second gear 620 pushes the second end of the second locking block 810 through the second locking slot 820 to compress the second elastic member 830. This causes the second end of the second locking block 810 to move at least partially out of the second locking slot 820. In other words, during the forward rotation of the second gear 620, the second gear 620 of the gear set 600 is decoupled from the second drive block 300. As a result, when the second gear 620 is driven by the first gear 610, it will not cause the second drive block 300 to rotate relative to the second rotating shaft 120, thereby preventing the second pedal 320 from being raised. When the second pedal 320 is pressed, it drives the second drive block 300 to rotate forward. Since the second locking block 810 is engaged in the second locking slot 820, the second drive block 300 and the second gear 620 remain stationary relative to each other. The second gear 620 rotates forward under the drive of the second drive block 300. During this process, the second gear 620 drives the first gear 610 to rotate forward, causing the first gear 610 to push the second end of the first locking block 710 through the first locking slot 720 to compress the first elastic member 730. This causes the second end of the first locking block 710 to move at least partially out of the first locking slot 720. In other words, during the forward rotation of the first gear 610, the first gear 610 of the gear set 600 is decoupled from the first drive block 200. As a result, when the first gear 610 is driven by the second gear 620, it will not cause the first drive block 200 to rotate relative to the first rotating shaft 110, thereby preventing the first pedal 220 from being raised.

[0078] It should be noted that, in the embodiments of this application, see... Figure 2 and Figure 6 As shown, the first gear 610 is provided with a first extension 611, which has an annular structure and is sleeved on the first rotating shaft 110 and coaxial with the first gear 610. A first slot 720 is provided on the circumferential outer wall of the first extension 611 of the first gear 610. The second gear 620 is provided with a second extension 621, which has an annular structure and is sleeved on the second rotating shaft 120 and coaxial with the second gear 620. A second slot 820 is provided on the circumferential outer wall of the second extension 621 of the second gear 620.

[0079] In some implementations, see Figure 2 and Figure 7 As shown, a third elastic member 612 is provided on at least one of the first gear 610 and the second gear 620. Exemplarily, the third elastic member 612 has a first end and a second end that are positioned opposite each other. The first end of the third elastic member 612 is connected to the first gear 610, and the second end of the third elastic member 612 is connected to the mounting bracket 100.

[0080] Understandably, when the first pedal 220 is pressed, the first drive block 200 rotates forward, and the first gear 610 rotates forward along with the first drive block 200 through the deformation of the third elastic element 612. At the same time, the second gear 620 rotates forward under the drive of the first gear 610. When the driver's foot is removed from the first pedal 220, the first drive block 200 rotates in the opposite direction under the action of the first clamping plate 400 and the second clamping plate 500 and returns to a parallel state with the second drive block 300. The first gear 610 rotates in the opposite direction under the action of the third elastic element 612, and the first gear 610 synchronously drives the second gear 620 to rotate in the opposite direction. This allows the second end of the first locking block 710 to remain inserted into the first locking groove 720, and the second end of the second locking block 810 to remain inserted into the second locking groove 820. When the second pedal 320 is pressed, the second drive block 300 rotates in the forward direction, and the second gear 620 rotates in the forward direction due to the deformation of the third elastic element 612. When the driver's foot is removed from the second pedal 320, the first drive block 200 rotates in the reverse direction under the action of the first clamping plate 400 and the second clamping plate 500 and returns to a state parallel to the second drive block 300. The first gear 610 rotates in the reverse direction under the action of the third elastic element 612, and the second gear 620 rotates in the reverse direction under the drive of the first gear 610. This allows the second end of the first locking block 710 to remain inserted into the first locking groove 720, and the second end of the second locking block 810 to remain inserted into the second locking groove 820.

[0081] It should be noted that the third elastic element 612 includes, but is not limited to, components with elastic properties such as springs or rubber.

[0082] In some implementations, see Figure 2 and Figure 7 As shown, the gear set 600 also includes a third gear 630 and a fourth gear 640. Both the third gear 630 and the fourth gear 640 are mounted on the mounting bracket 100 and are rotatable relative to the mounting bracket 100. The third gear 630 and the fourth gear 640 mesh with each other, and the third gear 630 also meshes with the first gear 610, while the fourth gear 640 meshes with the second gear 620.

[0083] In this embodiment, the first gear 610 and the second gear 620 are indirectly linked through the third gear 630 and the fourth gear 640.

[0084] It is understood that when the first gear 610 rotates in the forward direction, the second gear 620 rotates in the forward direction through the transmission of the third gear 630 and the fourth gear 640. When the first gear 610 rotates in the reverse direction, the second gear 620 rotates in the reverse direction through the transmission of the third gear 630 and the fourth gear 640. In this embodiment, the direction of the forward rotation of the first gear 610 is opposite to the direction of the forward rotation of the second gear 620. That is, when the first gear 610 rotates counterclockwise, the third gear 630 rotates clockwise, the fourth gear 640 rotates counterclockwise, and the second gear 620 rotates clockwise; when the first gear 610 rotates clockwise, the second gear 620 rotates counterclockwise.

[0085] In some implementations, see Figure 1 and Figure 2 As shown, an acceleration potentiometer 130 is provided on the mounting bracket 100. The acceleration potentiometer 130 is used to detect the rotation angle of the third gear 630, and the acceleration potentiometer 130 can be communicatively or electrically connected to an external controller. When the driver presses the first pedal 220 or the second pedal 320, the acceleration potentiometer 130 can feed back the rotation angle information of the third gear 630 to the external controller, thereby enabling the external controller to analyze the rotation angle information and perform corresponding operations.

[0086] In some implementations, see Figure 2 , Figure 4 and Figure 8 As shown, the second pedal 320 and the second drive block 300 are separate structures. The second pedal 320 is rotatably mounted on the first rotating shaft 110, and the second pedal 320 and the second drive block 300 abut against each other. When the second pedal 320 is pressed down, the second pedal 320 can push the second drive block 300 to rotate relative to the second rotating shaft 120.

[0087] In some embodiments, the first drive block 200, the first gear 610, and the second pedal 320 are all mounted on the first rotating shaft 110 via bearings, so that the first drive block 200, the first gear 610, and the second pedal 320 can rotate relative to the first rotating shaft 110. The second drive block 300 and the second gear 620 are both mounted on the second rotating shaft 120 via bearings, so that the second drive block 300 and the second gear 620 can rotate relative to the second rotating shaft 120.

[0088] In some implementations, see Figure 5As shown, a first abutment 250 and a second abutment 260 are provided on the side of the first driving block 200 near the second driving block 300, and a third abutment 350 and a fourth abutment 360 are provided on the side of the second driving block 300 near the first driving block 200. The first abutment 250 and the second abutment 260 are spaced apart in the first direction X, and the third abutment 350 and the fourth abutment 360 are also spaced apart in the first direction X. When the first driving block 200 and the second driving block 300 are parallel to each other, the first abutment 250 corresponds to the third abutment 350 in the direction perpendicular to the first direction X, and the second abutment 260 corresponds to the fourth abutment 360 in the direction perpendicular to the first direction X.

[0089] In this embodiment, when the first pedal 220 is pressed, the first drive block 200 rotates in the forward direction. During this process, the second abutment block 260 moves toward the third abutment block 350 until the second abutment block 260 abuts against the third abutment block 350, so that the first pedal 220 is pressed to its maximum stroke. When the second pedal 320 is pressed, the second drive block 300 rotates in the forward direction. During this process, the fourth abutment block 360 moves toward the first abutment block 250 until the fourth abutment block 360 abuts against the first abutment block 250, so that the second pedal 320 is pressed to its maximum stroke.

[0090] It is worth mentioning that the mutual abutment of the first abutment block 250 and the fourth abutment block 360, as well as the mutual abutment of the third abutment block 350 and the second abutment block 260, can better achieve the interlocking between the first drive block 200 and the second drive block 300, thereby improving the stability and safety of the entire dual-pedal mechanism.

[0091] It is understandable that another interlocking mechanism may be provided between the first drive block 200 and the second drive block 300, and there are no special restrictions on this.

[0092] Secondly, this application provides an engineering vehicle that includes the aforementioned dual-pedal mechanism, thus possessing the corresponding technical effects and advantages.

[0093] The engineering vehicles in this application embodiment include, but are not limited to, forklifts, excavators, cranes, and loaders.
