[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] like Figures 1-4 As shown, a side-mounted rail assist assembly includes an assist support plate 1, an assist sleeve 2, a pedal 3, and an assist mechanism. The assist support plate 1 is provided with mounting holes. Using bolts and other mounting components, the assist support plate 1 can be installed and connected to the cab of the agricultural machinery through the mounting holes. In actual use, the assist support plate 1 is installed in the cab of the agricultural machinery and is in an upright state. The assist sleeve 2, pedal 3, assist mechanism, etc. are installed on the side end face of the assist support plate 1. Compared with existing similar products, it effectively reduces the space required for the installation of the assist assembly and reduces the installation difficulty of the assist assembly.

[0018] A power assist shaft is vertically mounted on the side end face of the power assist support plate 1. A power assist sleeve 2 is fitted onto the power assist shaft. The power assist sleeve is connected to the power assist shaft via a bearing structure. The power assist sleeve 2 can rotate relative to the power assist shaft, and its axis of rotation is the axis of the power assist shaft. A clutch connection part is provided on the power assist sleeve 2 for connection with the clutch of the agricultural machinery. The pedal 3 is directly connected to the power assist sleeve 2 or indirectly connected to it via a power assist shift fork 5. When the driver depresses the pedal 3, it drives the power assist sleeve 2 to rotate, thereby triggering the corresponding clutch action. A home position stop 8 is provided on the power assist sleeve 2, and a home position baffle 9 is provided on the power assist support plate 1. When the pedal 3 is in the home position, the power assist sleeve 2 rotates to the position where the home position stop 8 and the home position baffle 9 abut. The home position baffle 9 prevents the power assist sleeve 2 from rotating further. The cooperation between the home position stop 8 and the home position baffle 9 allows the pedal 3 to return to its home position during the reset process.

[0019] The assist mechanism includes an elastic support member 4, an assist fork 5, a mounting component, and a track plate 6. The assist fork 5 is connected to the assist sleeve 2, and when the assist sleeve 2 rotates, it drives the assist fork 5 to rotate around the assist shaft. The track plate 6 and the connecting component are connected to the assist support plate 1. The elastic support member 4 is a prior art elastic telescopic component, which has been patented by the applicant (application number 202521154543.9), and will not be described in detail in this utility model. In addition, the elastic support member 4 can also adopt other forms of elastic telescopic components in the prior art. The elastic support member 4 is connected to the connecting component and rotates relative to the connecting component. The rotation axis of the elastic support member 4 is parallel to the axis of the assist shaft, and the top support part of the elastic support member 4 cooperates with the assist fork 5. An assist track surface 11 is provided on the track plate 6, and an assist wheel 10 is also provided at the top support part of the elastic support member 4. The assist wheel 10 abuts against the assist track surface 11.

[0020] Under the elastic support of the elastic support member 4, the assist wheel 10 abuts against the assist track surface 11, and the assist fork 5 always engages with the support part of the elastic support member 4, preventing the support part from disengaging from the assist fork 5 and thus causing the elastic support member 4 to lose control. For ease of description, the perpendicular line connecting the rotation axis of the elastic support member relative to the connecting member and the rotation axis of the assist sleeve 2 is called the rotation center line 7, as shown in the figure. Figure 3As shown by the dashed line, when the driver presses pedal 3, the power assist sleeve 2 and the power assist fork 5 are driven to rotate around the power assist shaft, and the power assist wheel 10 travels along the power assist track surface 11. During this process, the distance between the contact position of the power assist wheel 10 and the power assist track surface 11 and the rotation axis of the elastic support member 4 changes. The elastic support member 4 extends under its own elasticity. Because the direction of action of the elastic support member 4 is biased towards one side of the rotation center line 7, the force exerted by the elastic support member 4 when it extends is applied to the power assist sleeve 2 through the power assist fork 5. The direction of this force does not intersect with the axis of the power assist sleeve 2, thereby generating a power assist torque that drives the power assist sleeve 2 to rotate, assisting the driver in pressing pedal 3.

[0021] For details, please refer to Figure 3 , Figure 3 The dashed line represents the rotation center line 7, which is the perpendicular line connecting the rotation axis of the elastic support relative to the connecting member and the rotation axis of the power assist sleeve 2. The power assist track surface 11 includes a power assist reset track surface and a power assist pedaling track surface, located on opposite sides of the rotation center line 7. The power assist reset track surface is on the right side of the rotation center line 7 and is an arc surface with its center near the connecting member. When the power assist wheel 10 engages with the power assist reset track surface, the power assist wheel 10 is on the right side of the rotation center line 7. The elastic support has an elongation tendency and generates a power assist torque that drives the power assist sleeve 2 to rotate counterclockwise. When the in-position stop 8 engages with the in-position stop... When the pedal 9 is in contact, the pedal 3 is in its original position; the power assist track surface is to the left of the rotation center line 7. The power assist track surface is an arc surface. The center of the power assist pedal 3 track surface coincides with the rotation axis of the power assist sleeve 2. When the power assist wheel 10 is in contact with the power assist track surface, the power assist wheel 10 is to the left of the rotation center line 7. Under the elastic action of the elastic support, the power assist wheel 10 has a tendency to roll along the power assist track surface, thereby generating a power assist torque that drives the power assist sleeve 2 to rotate clockwise, assisting the driver to press the pedal 3.

[0022] The power assist fork 5 includes two fork plates. One end of the fork plate is connected to the power assist sleeve 2, and the other end is provided with a fork groove. The surfaces of the two fork plates face each other so that the positions of the two fork grooves correspond. The top support of the elastic support member is embedded in the fork groove of each fork plate. The top support of the elastic support member can rotate relative to the fork plate and can move in the fork groove according to the support state of the power assist track surface 11. Within a certain rotation range, the top support of the elastic top support member 4 cannot disengage from the fork groove.

[0023] The assist plate 1 is provided with a support column, the track plate 6 is connected to the support column and the assist track surface 11 is located between the two shift fork plates, the top support part of the elastic top support 4 is provided with a top support shaft, the top support shaft is parallel to the assist shaft, the assist wheel 10 is provided on the top support shaft, and the top support shaft is provided with top support wheels on both sides of the assist wheel 10. While the assist wheel 10 is in contact with the assist track surface 11, the two top support wheels are respectively in the shift fork grooves of the two shift fork plates and in contact with the inner wall of the shift fork groove.

[0024] In some embodiments, the mounting component is connected to the track plate 6 so that the elastic support is positioned at the corresponding assist track surface 11. Of course, the mounting component may also be made from the same plate as the track plate 6.

[0025] In this specification, the terms "an embodiment," "example," "specific example," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
