Description

Technical Field

[0001] This utility model relates to the field of carbon-free vehicle technology, specifically to a dual-fine-adjustment slide rail type carbon-free vehicle steering mechanism. Background Technology

[0002] The carbon-free car is a three-wheeled vehicle with continuous obstacle avoidance capabilities, powered solely by Joule gravitational potential energy, achieving true carbon-free operation. The car's lever mechanism replaces the traditional rigid rod with a flexible rope, making turning easier and obstacle avoidance cycles more precise and controllable, while also reducing overall weight. Using plexiglass wheels facilitates differential speed control and reduces the coefficient of friction between the wheels and the ground. The overall structure is simple, with low friction loss, high efficiency, and ease of manufacturing and installation. Potential for adoption: It can meet the practical experimental and understanding needs of junior high, high school, and university students, commercialize it to stimulate young people's enthusiasm for mechanical structures, and can be placed in science museums to allow the public to appreciate the ingenuity of mechanical construction.

[0003] A search revealed that in the prior art, application number 202120003752.9, application date 2021.01.04, describes a finely adjustable carbon-free trolley steering mechanism. During operation, the cam remains in contact with the hemispherical section of the fine-tuning push rod, effectively avoiding errors caused by cam thickness and making the trolley trajectory closer to the expected path. When the cam is not rotating, the distance between the slider and the cam center can be changed by rotating the fine-tuning push rod. This fine-tuning method is simple in structure and easy to implement. The mounting shaft on the upper part of the slider and the slide groove are fitted together through a slide groove flange bearing, reducing friction during operation. The front wheel support frame is fitted together with the support frame flange bearing and the front insert through a slide groove flange bearing, further reducing friction during wheel rotation.

[0004] However, the above structure still has shortcomings. It eliminates some of the errors in the parts processing and assembly process of the carbon-free trolley, but it can only change the distance between the slider and the center of the cam, and cannot fine-tune the steering offset error between the steering wheel and the rotating shaft. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-fine-adjustment slide rail type carbon-free trolley steering mechanism, which has the advantages of adjusting the spacing between the parts of the carbon-free trolley, reducing and compensating for the errors existing in the actual processing and assembly of each part, and improving the running accuracy of the whole vehicle, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-fine-adjustment slide rail type carbon-free trolley steering mechanism, comprising a moving component, a first adjusting component, and a second adjusting component. The first adjusting component is disposed on the moving component for fine-tuning the left and right movement of the carbon-free trolley. The second adjusting component is disposed on the first adjusting component for fine-tuning the forward and backward movement of the carbon-free trolley. The first adjusting component includes a convex plate, a slider, a slide rail, a screw, a knob, a folding plate, and a cylinder. The convex plate is disposed on the moving component, the slider is fixedly mounted on the convex plate by fasteners, and the slide rail is slidably mounted on the slider. The first screw is rotatably mounted on the slide rail and is threadedly connected to the slider. The first knob is fixedly mounted on one end of the first screw. The second folding plate is fixedly mounted on the top of the slide rail. The third cylinder is rotatably mounted on the folding plate. The fourth adjustment assembly includes a connecting plate, a fifth screw, a second knob, a push block, a rectangular block, and a fixing frame. The connecting plate is rotatably mounted on the cylinder. The fifth screw is threadedly mounted on the connecting plate. The sixth knob is fixedly mounted on one end of the second screw. The seventh push block is rotatably mounted on one end of the second screw. The eighth rectangular block is fixedly mounted on the bottom of the push block. The ninth fixing frame is fixedly mounted on the bottom of the rectangular block.

[0007] Furthermore, the folding plate is zig-shaped, the protrusion of the slider is trapezoidal, the recess of the slide rail is trapezoidal, and the slider is adapted to the slide rail.

[0008] Furthermore, the movable component includes a roller, a mounting bracket, a connecting rod, and a protective frame. The mounting bracket is rotatably mounted on the roller, the connecting rod is fixedly mounted on the mounting bracket, the protective frame is rotatably mounted on the connecting rod, and the protruding plate is fixedly mounted on the top end of the connecting rod.

[0009] Furthermore, the cross-section of the protective frame is set in a Z-shape.

[0010] Furthermore, the bottom of the push block is provided with a groove, which is adapted to fit the rectangular block.

[0011] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0012] This utility model, by setting a first adjustment component, allows for fine-tuning of the left and right spacing of parts in a carbon-free trolley. By turning a knob clockwise, the knob rotates and drives a screw to rotate. The screw rotates on a slide rail, simultaneously moving a slider. The slider moves along the slide rail, and its direction and position are constrained by the slide rail. The slider's movement also drives a convex plate, which in turn moves a connecting rod. The connecting rod then moves the mounting bracket and rollers. This design allows for the forward and backward adjustment of the carbon-free trolley's components, reducing and compensating for errors in the actual processing and assembly of each part, and improving the overall vehicle's operational accuracy.

[0013] This utility model, by setting a second adjustment component, allows for the rotation of a second knob, which in turn drives a second screw to rotate clockwise. The second screw rotates and moves on the connecting plate, pushing a push block as it moves. The push block moves under the push of the second screw, which in turn moves a rectangular block, which in turn moves a fixed frame. This allows for the adjustment of the front-to-back position and spacing of the components of the carbon-free trolley, reducing and compensating for errors that may occur during the actual processing and assembly of the parts.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides, for example Figures 1-4 As shown, a dual-fine-adjustment slide rail type carbon-free trolley steering mechanism includes a moving component, a first adjustment component, and a second adjustment component. The first adjustment component is mounted on the moving component for fine-tuning the left and right movement of the carbon-free trolley. The second adjustment component is mounted on the first adjustment component for fine-tuning the forward and backward movement of the carbon-free trolley. The first adjustment component includes a convex plate 5, a slider 6, a slide rail 7, a screw 8, a knob 9, a folding plate 10, and a cylinder 11. The convex plate 5 is mounted on the moving component. The slider 6 is fixedly mounted on the convex plate 5 by fasteners. The slide rail 7 is slidably mounted on the slider 6. The screw 8 is rotatably mounted on the slide rail. On slide rail 7, screw 8 is threadedly connected to slider 6, knob 9 is fixedly mounted on one end of screw 8, folding plate 10 is fixedly mounted on the top of slide rail 7, and cylinder 11 is rotatably mounted on folding plate 10. The second adjustment assembly includes connecting plate 12, screw 13, knob 14, push block 15, rectangular block 16, and fixing frame 17. Connecting plate 12 is rotatably mounted on cylinder 11, screw 13 is threadedly mounted on connecting plate 12, knob 14 is fixedly mounted on one end of screw 13, push block 15 is rotatably mounted on one end of screw 13, and rectangular block 16 is fixedly mounted on push block 15. At the bottom, the fixing bracket 17 is fixedly installed at the bottom of the rectangular block 16. More specifically, when the carbon-free trolley needs to make fine adjustments to the left and right spacing of the parts, the knob 9 is turned clockwise, which drives the screw 8 to rotate. The screw 8 rotates on the slide rail 7, and at the same time, the screw 8 drives the slider 6 to move. The slider 6 moves on the slide rail 7, and the slider 6 is constrained in its direction and position by the slide rail 7. When the slider 6 moves, it drives the convex plate 5 to move, and the convex plate 5 drives the connecting rod 3 to move. The connecting rod 3 drives the mounting bracket 2 and the roller 1 to move, which can adjust the parts of the carbon-free trolley back and forth, reduce and compensate for the various parts. To address the errors present in the actual processing and assembly of parts, and to improve the overall vehicle's operational accuracy, the knob 14 is turned, causing the screw 13 to rotate clockwise. The screw 13 rotates and moves on the connecting plate 12. As the screw 13 moves, it pushes the push block 15, which moves under the push of the screw 13. The push block 15 then moves the rectangular block 16, which in turn moves the fixing frame 17, adjusting the front and rear positions and spacing. This method has the advantage of adjusting the front and rear positions and spacing of the carbon-free vehicle's parts, reducing and compensating for errors present in the actual processing and assembly of each part.

[0021] In addition, the folding plate 10 is zigzag-shaped, the protrusion of the slider 6 is trapezoidal, the recess of the slide rail 7 is trapezoidal, and the slider 6 is adapted to the slide rail 7.

[0022] like Figure 1 As shown, the movable component includes a roller 1, a mounting frame 2, a connecting rod 3, and a protective frame 4. The mounting frame 2 is rotatably mounted on the roller 1, the connecting rod 3 is fixedly mounted on the mounting frame 2, the protective frame 4 is rotatably mounted on the connecting rod 3, and the protruding plate 5 is fixedly mounted on the top end of the connecting rod 3.

[0023] In addition, the cross-section of the protective frame 4 is set in a Z-shape.

[0024] In some embodiments, the bottom of the pusher block 15 is provided with a groove, which is adapted to the rectangular block 16.

[0025] Working principle:

[0026] Step 1: Left and right adjustment. When the carbon-free trolley needs to fine-tune the left and right spacing of the parts, turn knob 9. Knob 9 rotates clockwise and drives screw 8 to rotate. Screw 8 rotates on slide rail 7. While rotating, screw 8 drives slider 6 to move. Screw 6 moves on slide rail 7 and is constrained in its direction and position by slide rail 7. When slider 6 moves, it drives convex plate 5 to move. Convex plate 5 drives connecting rod 3 to move. Connecting rod 3 drives mounting bracket 2 and roller 1 to move, thus adjusting the left and right position and spacing.

[0027] Step 2: Adjust the position and spacing by turning knob 14. Knob 14 drives screw 13 to rotate clockwise. Screw 13 rotates and moves on connecting plate 12. When screw 13 moves, it pushes push block 15. Push block 15 moves under the push of screw 13. Push block 15 drives rectangular block 16 to move. Rectangular block 16 drives fixed frame 17 to move, thus adjusting the position and spacing.
