Description

Technical Field

[0001] The present application relates to the technical field of educational science tools, and in particular to a crank mechanism display device for simulating cycling. Background Art

[0002] As an important transmission mechanism, the crank-connecting rod mechanism is used in many mechanical devices. It converts circular motion into linear motion, or converts linear motion into circular motion. As a basic transmission mechanism in the mechanical field, it is required to be studied in the mechanical majors of various universities. Teachers have also developed various teaching aids to show the principles and actions to students vividly and objectively.

[0003] However, the above-mentioned teaching aids are all for adults, and the teaching objects are college or undergraduate students. They have strong teaching attributes and cannot be used for popularizing science for children. It is not convenient for children to connect and compare with their daily life, so that they can understand the role and use of the crank-connecting rod mechanism more vividly. Therefore, the teaching and popularization effects are not good. Utility Model Content

[0004] The purpose of the present application is to provide a crank mechanism display device for children to simulate riding a bicycle, which targets children's cognition, links real life with popular science, and more vividly displays the principles and uses of the crank-connecting rod mechanism, thereby improving the effects of popular science and teaching.

[0005] The embodiment of the present application is implemented as follows:

[0006] An embodiment of the present application provides a crank mechanism display device for simulating cycling, comprising a fixed plate, characterized in that a bicycle and a cartoon model sitting on a bicycle seat are arranged on one side of the fixed plate, and a rotating shaft rotatably connected to the fixed plate is arranged on the other side, the bicycle comprises a rear wheel and a pedal wheel, the rear wheel is fixedly connected to the rotating shaft, a transmission assembly is arranged between the pedal wheel and the rear wheel, the rotating shaft drives the rear wheel to rotate and transmits power to the pedal wheel through the transmission assembly, the outer edge of the pedal wheel is hinged to the calf part of the cartoon model, the other end of the calf part is connected to the thigh part, and the other end of the thigh part is connected to the torso part.

[0007] Through the above technical scheme, the cartoon model and the bicycle are combined to simulate the state of people riding bicycles in life. The difference is that the rear wheel is rotated and the transmission component drives the pedal wheel to rotate, and then the pedal wheel drives the calf part to move. The pedal wheel is the crank, and the thigh part and the calf part are the connecting rods. When the pedal wheel rotates, the thigh part and the calf part drive the torso part to lift and sit down, so as to explain the knowledge of the crank-connecting rod mechanism to children, and the cartoon characters can attract the attention of children better. Riding a bicycle is a common scene in life, which is convenient for children to connect and compare with the scenes in their daily life. When they see the scene repeatedly in their daily life, they can repeatedly strengthen their memory of the crank-connecting rod mechanism and understand the principle thereof.

[0008] In some embodiments of the present application, the transmission assembly includes two transmission wheels respectively arranged on the rear wheel and the pedal wheel and rotating with the rear wheel and the pedal wheel, and also includes a transmission belt arranged between the two transmission wheels, which further increases the knowledge points of the teaching aid and makes it closer to the bicycle in life, thereby improving the teaching effect.

[0009] In some embodiments of the present application, a horizontal slide groove is provided on the fixed plate, a slider is provided in the slide groove, the front wheel of the bicycle is fixed on the slider, the connection between the front fork of the bicycle and the frame and the arm of the cartoon model is hinged, an eccentric wheel is provided on the rotating shaft, a connecting rod is hinged between the outer edge of the eccentric wheel and the slider, a connecting rod is provided on the back side of the fixed plate and is connected to the eccentric wheel through a ring, the eccentric wheel acts as a crank, and the rotation of the eccentric wheel drives the slider to move, thereby driving the front wheel of the bicycle to move forward and backward, simulating the scene of the bicycle moving forward, making the teaching aids more vivid and flexible, and improving the teaching effect.

[0010] In some embodiments of the present application, a rotating handle is provided on the eccentric wheel, and a ring is provided at the end of the connecting rod and is sleeved on the eccentric wheel. During teaching, the teacher can manually rotate the rotating handle or set a small motor for driving.

[0011] In some embodiments of the present application, the head of the cartoon model is hinged to the torso, and a driving wire is hinged between the head and the rear wheel. The driving wire is hinged to the outer edge of the rear wheel. The head and the torso are hinged, and when the rear wheel rotates, the driving wire drives the head to rotate, which can more vividly simulate the movements of the cartoon model when riding a bicycle, making the model more vivid and lifelike.

[0012] In some embodiments of the present application, the cartoon model is an animal or a human.

[0013] In some embodiments of the present application, the fixing plate, the bicycle and the cartoon model are all painted with colors of macaron colors.

[0014] Compared with the prior art, the embodiments of the present application have at least the following advantages or beneficial effects:

[0015] First, combine the cartoon model with the bicycle to simulate the state of people riding bicycles in real life, so as to explain the knowledge of crank-connecting rod mechanism to the children. The cartoon model can better attract the children's attention. Riding a bicycle is a common scene in life, which is convenient for children to connect and compare the scenes with their daily lives. When they see the scene repeatedly in their daily lives, they can repeatedly strengthen their memory of the crank-connecting rod mechanism and understand the principles behind it.

[0016] Secondly, the front wheel, the head and the rear wheel of the bicycle are driven by multiple connecting rod mechanisms, making the entire teaching aid more vivid and flexible, and improving the teaching effect. BRIEF DESCRIPTION OF THE DRAWINGS
