Description

Technical Field

[0001] The utility model relates to a water-powered trolley model toy, belonging to the technical field of educational equipment. Background Technique

[0002] Play teaching aids, as an important tool for early childhood education, can not only stimulate children's imagination and creativity, but also help them understand abstract concepts. In physics, the conversion of energy is one of the basic principles, which describes that energy can be converted from one form to another. For young children, it may be a bit difficult to understand this concept, but through appropriate play teaching aids, they can feel and understand the process of energy conversion through intuitive game experiences.

[0003] Toy cars, as a kind of toy that children often come into contact with, are deeply loved by children. However, current toy cars are usually driven by motors and generally only serve for children to play without teaching functions, and children cannot intuitively feel the energy conversion.

[0004] A wind-powered trolley for teaching aids and toys disclosed in the Chinese utility model patent with the publication number CN210543322U includes: a vehicle body, a power supply is arranged on the vehicle body, and a first wheel set and a second wheel set are respectively arranged at both ends of the vehicle body; a loading platform, the loading platform is arranged on the vehicle body, a control circuit board and a switch circuit board are arranged on the loading platform, and universal seats are arranged on both sides of the loading platform; a fan blade assembly, the fan blade assembly includes: a motor arranged at the end of the universal seat, and a fan blade member connected to the output end of the motor.

[0005] The power of the above reference example is still provided by the motor, and children cannot intuitively feel and observe the energy conversion. Moreover, the structure of the wind-powered trolley is relatively complex, and the internal mechanical transmission cannot be directly observed, resulting in poor teaching effects. Therefore, improvement is urgently needed. Content of the Utility Model

[0006] In order to overcome the shortcomings that existing toy car play teaching aids cannot enable children to intuitively feel energy conversion and have a complex structure that is not convenient for children to observe, the utility model designs a water-powered trolley model toy, which is convenient to observe, has a simple structure, and can help children intuitively feel the energy conversion from gravitational potential energy to mechanical energy.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A hydrodynamic trolley model toy, comprising a moving frame. Moving components for movement are provided at both the front and rear ends of the moving frame. The moving components include a connecting shaft and moving wheels installed at both ends of the connecting shaft. An installation frame is fixedly installed at the top of the moving frame.

[0009] Further, the installation frame includes four vertically arranged vertical rods and a frame fixedly connected to the top ends of the respective vertical rods. The water storage bucket is fixedly installed on the frame. The four vertical rods are arranged in a rectangle, and connecting rods surrounding a rectangle are connected between the respective vertical rods.

[0010] Further, the transmission component includes a transmission belt and belt pulleys in transmission connection with the transmission belt. The belt pulleys include a driving belt pulley and a driven belt pulley. The driving belt pulley is coaxially connected to the impeller through a rotating shaft, and the rotating shaft is rotatably installed on one of the vertical rods. The driven belt pulley is fixedly sleeved on the connecting shaft.

[0011] Further, an elastic water collecting tank communicating with the inside of the installation frame is installed at the bottom end of the moving frame.

[0012] Further, a friction pad is fixed at the bottom end of the water collecting tank.

[0013] Further, a water pumping mechanism is arranged between the water collecting tank and the water storage bucket. The water pumping mechanism includes a water pump and a water suction pipe. One end of the water suction pipe is arranged at the bottom end of the water collecting tank, and the other end penetrates through the side wall of the water storage bucket and communicates with the water storage bucket.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be described in more detail below with reference to the embodiments.

[0025] As Figures 1 to 2 shown, the water-powered trolley model toy of this embodiment includes a moving frame 8. Moving components for moving are arranged at both the front and rear ends of the moving frame 8. The moving components include a connecting shaft 6 and moving wheels 7 installed at both ends of the connecting shaft 6. A mounting frame 3 is fixedly installed at the top end of the moving frame 8. A water storage bucket 1 is fixed at the top end of the mounting frame 3. The bottom end of the water storage bucket 1 is communicated with a water outlet pipe 2. The bottom end of the water outlet pipe 2 is arranged inside the mounting frame 3, and an impeller 4 rotatably installed on the mounting frame 3 is arranged at the lower end of the water outlet pipe 2. The impeller 4 is in transmission connection with one of the connecting shafts 6 through a transmission component.

[0026] As can be seen from the above description, the beneficial effects of the present utility model are as follows: By providing the water storage bucket 1, a certain amount of clean water can be stored, and then the water is released downward from a high place through the water outlet pipe 2, so that the clean water impacts the impeller 4. As a result, the impeller 4 can rotate, and the connecting shaft 6 is driven to rotate through the transmission assembly, thereby realizing the movement of the moving frame 8. Through the impact of water from a high place to a low place, the gravitational potential energy can be converted into mechanical energy, and the motion phenomenon is obvious, which is convenient for children to understand and observe. Children can intuitively feel the process of energy conversion, thereby deepening their understanding of physical principles, effectively improving the teaching effect, stimulating children's interest in scientific exploration, and cultivating their observation ability and thinking ability.

[0027] Further, the mounting frame 3 includes four vertically arranged vertical rods and a frame 18 fixedly connected to the top ends of the vertical rods. The water storage bucket 1 is fixedly installed on the frame 18. The four vertical rods are arranged in a rectangle, and connecting rods 12 that enclose a rectangle are connected between the vertical rods. The connecting rods 12 are provided to enhance the stability of the mounting frame 3.

[0028] Further, the transmission assembly includes a transmission belt 5 and belt pulleys that are in transmission connection with the transmission belt 5. The belt pulleys include a driving belt pulley 19 and a driven belt pulley 21. The driving belt pulley 19 is coaxially connected to the impeller 4 through a rotating shaft 20, and the rotating shaft 20 is rotatably installed on one of the vertical rods. The driven belt pulley 21 is fixedly sleeved on the connecting shaft 6. Belt transmission makes the trolley move more smoothly during the movement process.

[0029] Further, an elastic water collecting tank 10 that is in communication with the inside of the mounting frame 3 is installed at the bottom end of the moving frame 8, which is convenient for collecting the clean water discharged from the water outlet pipe 2.

[0030] Further, a friction pad 9 is fixed at the bottom end of the water collecting tank 10. When the water collecting tank 10 collects a certain weight of water, due to its elasticity, the friction pad 9 will contact the moving surface, and then the trolley can be braked through the friction pad 9, reminding the educator that the water volume in the water collecting tank 10 is relatively large and the teaching needs to be stopped.

[0031] Further, a water pumping mechanism is provided between the water collecting tank 10 and the water storage bucket 1. The water pumping mechanism includes a water pump 14 and a water suction pipe 13. One end of the water suction pipe 13 is arranged at the bottom end of the water collecting tank 10, and the other end penetrates through the side wall of the water storage bucket 1 and is communicated with the water storage bucket 1. The water pump 14 is installed on the water suction pipe 13 and is fixedly connected to the water storage bucket 1. The water pumping mechanism is convenient for pumping the water in the water collecting tank 10 into the water storage bucket 1, and the water can be recycled, which is efficient and convenient.

[0032] Further, the water outlet pipe 2 is arranged in a conical structure with a gradually decreasing diameter from top to bottom. At the same time, a valve body is provided on the water outlet pipe 2. The conical water outlet pipe 2 is convenient for water outlet and can provide greater impact power for the impeller 4. The valve body is provided to facilitate the control of the water output.

[0033] Further, a end cover 15 is provided on the top of the water storage bucket 1, and a pull ring 16 is fixed at the top of the end cover 15 to prevent the water in the water storage bucket 1 from spilling outwards.

[0034] Further, the end cover 15 is fixed to the side of the water storage bucket 1 through a connecting rope 17 to prevent the end cover 15 from being lost.

[0035] The working principle of the present utility model: Store a certain amount of clear water in the water storage bucket 1, and then open the valve body so that the water outlet pipe 2 releases the water from a high place downwards. The clear water impacts the impeller 4, and the impeller 4 rotates under the impact of the water, and drives the connecting shaft 6 to rotate through the transmission assembly, thereby realizing the movement of the moving frame 8.

[0036] During the movement of the moving frame 8, the clear water continuously gathers in the water collecting tank 10. When the water collecting tank 10 collects a certain weight of water, due to its elasticity, the friction pad 9 gradually contacts the moving surface, and finally brakes the trolley, reminding the educator that the water volume in the water collecting tank 10 is relatively large. In order to avoid overflow, first suspend the teaching, and then pump the clear water back into the water storage bucket 1 through the pumping mechanism to prevent the clear water from spilling and wasting.
