[0048] Embodiment 1

[0049] Refer to Figure 1-14 As shown in, an embodiment of this disclosure provides a transmission mechanism, which is used to be disposed in a continuously variable transmission and includes: a gear shifting member 2, a connecting plate 3, a speed regulating plate 4, a sliding rod 5, a first pull rod 6, a second pull rod 7 and a rotating assembly 8; the speed regulating plate 4 is hinged to the rotating assembly 8 through the first pull rod 6, and the speed regulating plate 4 is used to drive the rotating assembly 8 to switch between a disengaged state and an engaged state; wherein, the speed regulating plate 4 and the connecting plate 3 are coaxially arranged, one end of the second pull rod 7 is fixedly connected to both the speed regulating plate 4 and the connecting plate 3 at the same time, a sliding groove 31 penetrating the plate body of the connecting plate 3 is formed on the connecting plate 3, the first end of the sliding rod 5 is fixed on the gear shifting member 2, the second end of the sliding rod 5 penetrates the sliding groove 31 and slides in the sliding groove 31, and the gear shifting member 2 drives the gear shifting member 2 to switch between a forward gear, a reverse gear and a neutral gear by sliding the sliding rod 5 in the sliding groove 31.

[0050] Specifically, the rotating component 8 can be coaxially connected to the driving wheel 12 of the continuously variable transmission 1. During rotation, the rotating component 8 ascends in a spiral manner, changing the transmission ratio of the continuously variable transmission 1, thereby achieving the purpose of speed regulation. The more the rotating component 8 ascends, the faster the speed.

[0051] The above-mentioned rotating component 8 includes a slider 81 and a top block 82. During rotation, the slider 82 can ascend in a spiral manner and separate from the top block 81, that is, the above-mentioned separated state. When stationary, the slider 81 and the top block 82 are engaged, that is, the above-mentioned combined state.

[0052] Optionally, the rotating component 8 is in a shape similar to a cylinder, including a slider 81 and a top block 82. The outer surface of the slider 81 is provided with a first convex portion 811, and the inner surface is provided with a second convex portion 812. One end of the first pull rod 6 is fixedly connected to the first convex portion 811. The circular bottom of the top block 82 is provided with a third convex portion 821 similar to teeth. In the stationary state, the third convex portion 821 is engaged with the second convex portion 812.

[0053] In an optional embodiment, Figure 8 is a schematic diagram of the top block 82 and the slider 81 in the rotating component 8 in an optional embodiment of the present disclosure, Figure 9 is a schematic diagram of the structure of the transmission mechanism in the neutral state in an optional embodiment of the present disclosure. Refer to Figure 1 and Figure 9 , in the stationary state of neutral gear, the second convex portion 812 is engaged with the top block 82, the rotating component 8 is in the combined state, and the sliding rod 5 is located in the second strip-shaped hole 312.

[0054] Optionally, the gear shifting member 2 includes: a gear shifting wrench 23, a third pull rod 24, and a gear shifting mechanism 25. The gear shifting wrench 23 is hinged to the gear shifting mechanism 25 through the third pull rod 24.

[0055] In an optional embodiment, refer to Figure 3 , a connecting piece 26 is further fixed on the first fastener 9 for installing the gear shifting wrench 23. The connecting piece 26 is fixedly connected to the third pull rod 24. The gear shifting mechanism 25 includes a dial and a gear set fixedly connected to the third pull rod 24. When the gear shifting wrench 23 and the second fixing member 10 rotate, it drives the third pull rod 24 to axially move, and the dial in the gear shifting mechanism 25 will actively switch the meshing state of the gears in the gear set, thereby adjusting the rotation direction of the gear set. The rotation directions include forward rotation, reverse rotation, and no rotation, corresponding to the forward gear, reverse gear, and neutral gear respectively.

[0056] Optionally, the speed regulating plate 4 and the connecting plate 3 are rotatably installed on the housing 110 of the continuously variable transmission 1 through fasteners. In an optional embodiment, refer to Figure 2 , the speed regulating plate 4 and the connecting plate 3 can be installed on the housing 110 through the second fastener 10.

[0057] The above-mentioned first fastener 9 or second fastener 10 can be any combination of bolts, studs, nuts, and washers. The nuts can be selected according to actual needs, such as hexagonal nuts, square nuts, etc., and the present disclosure does not make any restrictions. The gear shifting member 2 is provided with a first hole 22, and the shape of the first hole 22 matches that of the first fastener 9. The first fastener 9 can pass through the first hole 22 to rotatably connect the gear shifting member 2 to the housing 110 of the continuously variable transmission 1.

[0058] The above-mentioned connecting plate 3 is provided with a second hole 32, and the speed regulating plate 4 is provided with a third hole 41. The second fastener 10 passes through the second hole 32 and the third hole 41 in sequence to rotatably mount the connecting plate 3 and the speed regulating plate 4 on the housing 110 of the continuously variable transmission 1.

[0059] In an alternative embodiment, a control component is connected to one end of the second pull rod 7 away from the connecting plate 3. The control component is used to control the traveling direction and speed of the device equipped with this transmission mechanism. For example, when the device is a riding mower, the control component can control the forward and backward movement of the riding mower, and at the same time control the speed of the riding mower through the control component. For example, the operating end of the control component can be a pedal or a pull rod. If it is a pedal, the user can control the traveling direction by manipulating the rotation direction of the pedal. For example, when the rotation direction of the pedal is clockwise rotation, the gear state is forward gear, and when the rotation direction is counterclockwise rotation, the gear state is reverse gear. The speed can be controlled by controlling the rotation angle of the pedal. For example, the larger the rotation angle, the faster the speed. In addition, the device provided with the control component can be any riding device capable of equipped with this transmission mechanism, such as a mower, a tractor, a snowplow, a seeding machine, etc.

[0060] Optionally, the gear shifting member 2 is provided with a connecting portion 21. The first end 51 of the sliding rod 5 is fixed to the connecting portion 21, and a plurality of uniformly distributed protrusions 511 are axially provided at the first end 51 of the sliding rod 5.

[0061] Optionally, the connecting portion 21 is a spline hole.

[0062] In an alternative embodiment, referring to Figure 4 、 Figure 5 and Figure 6 , the sliding rod 5 can be a spline shaft. The plurality of uniformly distributed protrusions 511 axially provided at the first end 51 of the sliding rod 5 are splines, and the second end 52 of the sliding rod 5 is a smooth end.

[0063] The above connecting plate 3 is further provided with a fourth hole 33, and the above speed regulating plate 4 is further provided with a fifth hole 42. One end of the second pull rod 7 passes through the fifth hole 42 and the fourth hole 33 in sequence and is fixedly connected to the speed regulating plate 4 and the connecting plate 3 respectively. When the second pull rod moves axially, it drives the connecting plate 3 and the speed regulating plate 4 to rotate in the same direction.

[0064] In the second pull rod 7 in the embodiment of the present disclosure, it is connected to both the connecting plate 3 and the speed regulating plate 4 at the same time. The speed regulating plate 4 drives the rotating assembly 8 to adjust the speed through the first pull rod 6. At the same time, the connecting plate 3 drives the shifting member 2 to rotate through the provided chute 31 and the slide bar 5 penetrating through the chute 31, driving the shifting member 2 to shift gears, achieving the purpose of automatic gear shifting, realizing the technical effect of automatically adjusting the gear when adjusting the speed, and thus solving the technical problem of manual gear shifting and cumbersome operation in the related art.

[0065] Optionally, the chute 31 includes a first strip-shaped hole 311, a second strip-shaped hole 312, and a third strip-shaped hole 313. When the second end 52 of the slide bar 5 is in the first strip-shaped hole 311, the gear state of the shifting member 2 is reverse gear. When the second end 52 of the slide bar 5 is in the second strip-shaped hole 312, the gear state is neutral gear. When the second end 52 of the slide bar 5 is in the third strip-shaped hole 313, the gear state is forward gear.

[0066] Optionally, the chute 31 further includes a first bending portion 314 and a second bending portion 315. The first strip-shaped hole 311 and the second strip-shaped hole 312 are connected through the first bending portion 314, and the second strip-shaped hole 312 and the third strip-shaped hole 313 are connected through the second bending portion 315. When the slide bar passes through the first bending portion 314 or the second bending portion 315 during the movement process, it drives the shifting member 2 to rotate.

[0067] In an optional embodiment, Figure 7 is the top view of the connecting plate 3 in an optional embodiment of the present disclosure. As Figure 7 shown, the first bending portion 314 has two bending points, and the second bending portion 315 has 1 bending point. It should be noted that when the slide bar 5 is between the two bending points of the first bending portion 314, it is usually in the critical state between neutral gear and reverse gear, and the transmission mechanism remains stationary.

[0068] Optionally, the third protrusion 821 includes a first hypotenuse 8211 and a second hypotenuse 8212. The slider 81 can rotate along the first hypotenuse 8211 or the second hypotenuse 8212 during the rotation process.

[0069] As an optional implementation manner, when the slide bar is in the first strip-shaped hole 311, the slider 81 rotates counterclockwise during the rotation process and rotates along the second hypotenuse 8212. When the slide bar is in the third strip-shaped hole 313, the slider 81 rotates clockwise and rotates along the first hypotenuse 8211.

[0070] Optionally, the slope of the first bevel edge 8211 is less than the slope of the second bevel edge 8212.

[0071] As an optional embodiment, Figure 10 is a three-dimensional structure diagram of the top block 82 in an optional embodiment of the present disclosure. The lengths and inclinations of the first bevel edge 8211 and the second bevel edge 8212 can be adjusted according to actual requirements. As Figure 2 shown, the rotating component 8 is arranged below the driving wheel 12 of the continuously variable transmission 1. During the ascending process of the slider 81 along the first bevel edge 8211 or the second bevel edge 8212, the transmission ratio of the pulley assembly can be adjusted to achieve the purpose of acceleration. On the contrary, for deceleration, according to the current gear state, the slider 81 can descend along the first bevel edge 8211 or the second bevel edge 8212 to achieve deceleration.

[0072] It should be noted that the slope of the first bevel edge part or the slope of the second bevel edge part can be adjusted according to the actual acceleration requirements during the actual R & D process.

[0073] Figure 11 is a three-dimensional structure diagram of the first perspective of the transmission mechanism in an optional embodiment of the present disclosure when the reverse gear speed is maximum. Figure 12 is a three-dimensional structure diagram of the second perspective of the transmission mechanism in an optional embodiment of the present disclosure when the reverse gear speed is maximum. As Figure 11 and Figure 12 shown, when the reverse gear speed is maximum, the rotating component 8 becomes longer in the height direction. Figure 13 is a three-dimensional structure diagram of the third perspective of the transmission mechanism in an optional embodiment of the present disclosure when the forward gear speed is maximum. Figure 14 is a three-dimensional structure diagram of the fourth perspective of the transmission mechanism in an optional embodiment of the present disclosure when the forward gear speed is maximum. As shown in FIGS. 13 and Figure 14 shown, when the forward gear speed is maximum, the rotating component 8 becomes longer in the height direction. It should be noted that, Figure 13 and Figure 14 in FIGS. 13 and 14, the other end 61 of the first locking rod is actually connected to the rotating component 8. Figure 13 and Figure 14 Only for showing a possible implementation manner of the connection between the other end 61 of the first locking rod and the rotating component 8, they are separated during drawing.

[0074] Optionally, a third fastener 11 is provided on the contact surface between the speed regulating plate 4 and the first pull rod 6.
