Detailed ways

The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

The embodiment of the utility model is as follows: as shown in Figures 1-2, a carbon-free trolley capable of walking in an "S" shape includes a vehicle frame and a driving mechanism arranged on the vehicle frame, and the vehicle frame includes a bottom plate 1 and a The guide mechanism 2 vertically arranged on the bottom plate 1; the driving mechanism includes a fixed pulley 3 arranged on the guide mechanism 2, and a wire rope is wound on the fixed pulley 3, and one end of the wire rope is connected with the potential energy block 4 arranged in the guide mechanism 2 connected, the other end of the cord is wound on a bobbin 5, and the bobbin 5 is linked with the rolling wheels and the steering mechanism arranged on both sides of the frame through a transmission mechanism; the steering mechanism includes a frame 9 arranged in sequence , the first connecting rod 10, the slider 11, the second connecting rod 12 and the steering wheel 13 located at the front end of the base plate 1, and the opposite sides of the inner side of the frame 9 are provided with incomplete gears 8 alternately meshed with the transmission mechanism The transmission teeth, the frame is fixedly connected with one end of the first connecting rod 10, the first connecting rod 10 is provided with a guide rail 14 capable of guiding the first connecting rod 10 to reciprocate along a straight line, the other of the first connecting rod 10 One end is connected with the slider 11 , the slider 11 is slidably connected with the second connecting rod 12 , and the second connecting rod 12 is fixedly connected with the steering wheel 12 .

The utility model has a simple and novel structure. The gravitational potential energy of the potential energy block 4 is converted into mechanical energy for the rotation of the winding shaft 5, and then transmitted through gears to provide power for the carbon-free trolley. The utilization rate of energy is high, and the running distance of the carbon-free trolley is long. The steering mechanism used is completed by the cooperation of incomplete gears 8, and the steering wheel 13 is constantly changing direction, thereby realizing that the trolley can walk in an "S" shape. In the trolley structure of the utility model, the operation of the carbon-free trolley is smoother and more stable, combined with a variety of representative mechanical structures, a carbon-free trolley suitable for mechanical mechanism teaching can be better provided.

In this embodiment, the transmission mechanism includes the first rotating shaft 6 driven by the winding shaft 5 through the gear set, the first rotating shaft 6 is linked with the second rotating shaft 7 through the transmission of the gear set, and the two ends of the second rotating shaft 7 are respectively connected to the The scroll wheels are interlocked, and one end of the first rotating shaft 6 is also interlocked with the incomplete gear 8. The other end of the first connecting rod 10 is hinged to the slider 11 . The bobbin 5 is conical. The guiding mechanism is three columns 2, and the columns 2 are evenly distributed around the potential energy block 4. Wherein, the guide mechanism can also be designed as a hollow sleeve. The utility model adopts structures such as brackets, which is convenient for students to observe the operation principle of the carbon-free trolley, and also facilitates the replacement of parts.

When the utility model is in use, the potential energy block 4 is first released so that it falls from a height in the three columns 2, and the column 2 restricts the vertical fall of the potential energy block 4, so that the wire rope is pulled, and the force direction is changed by the fixed pulley 3 , so that the winding shaft 5 rotates to provide power for the dolly. Then, driven by the gear set, the first rotating shaft 6 and the second rotating shaft 7 start to rotate. The second rotating shaft 7 links the rolling wheels at both ends to make the carbonless trolley start to move forward, and the first rotating shaft 6 will also rotate the incomplete gear 8 at one end, because the gears on both sides of the frame 9 mesh with the incomplete gear 8, as shown in Figure 3 As shown, the incomplete gear 8 rotates clockwise. When the gear turns to the upper side, the frame 9 drives the first connecting rod 10 to move forward. When the gear turns to the lower side, the frame 9 drives the first connecting rod 10 to move backward. , through the continuous rotation of the incomplete gear 8, the reciprocating movement of the first connecting rod 10 is realized, and the guide rail 14 on the first connecting rod 10 restricts the reciprocating movement of the first connecting rod 10 along a straight line, preventing the frame 9 from being separated from the incomplete gear 8 . The reciprocating motion of the first connecting rod 10 makes the slider 11 slide on the second connecting rod 12. Due to the action of the force, the linkage of the second connecting rod 12 will drive the steering wheel 13 to change the direction continuously, thus realizing the carbon-free trolley. "S" type steering movement.
