Description

Technical Field

[0001] This utility model relates to the field of children's toy technology, and in particular to a novel toy tractor head. Background Technology

[0002] In the current field of children's toy technology, toy tractor heads, as a classic mechanical toy category, have a large market share, but existing products have many technical defects in practical applications, making it difficult to meet the play needs of modern children and the quality requirements of parents.

[0003] Most existing electric toy tractors use a simple transmission structure where the motor directly connects to the wheels. That is, the motor output shaft is directly connected to the wheel axle through gears, and the motor drives the wheels forward or backward by reversing. Although this design can achieve autonomous driving, it cannot simulate the power transmission logic of a real tractor engine, gearbox, and drive shaft. It cannot reproduce the core characteristics of power transmission through multiple links in real machinery. When children play with it, they can only experience simple movement and cannot observe the complete process of mechanical transmission, thus losing the opportunity to learn about mechanical principles through toys. Utility Model Content

[0004] In view of the aforementioned problems with the user experience, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel toy tractor head, including a body, with a head fixedly installed at the front end of the body, and two rollers rotatably connected to the bottom end of the head for driving the body to move. The rollers are distributed on the left and right sides of the head. A rotating shaft is rotatably connected inside the head and fixedly connected to the opposite surfaces of the two rollers. A drive assembly for driving the rollers to roll is installed above the rotating shaft. A first pulley is rotatably connected to the side of the head near the rollers, and a rotating belt is rotatably connected to the circumferential surface of the first pulley. A second pulley is rotatably connected to the inner ring surface of the rotating belt.

[0006] As a preferred embodiment of the new toy tractor head of this utility model, the drive assembly includes a drive motor, a drive gear, and a driven gear. The output end of the drive motor is fixedly connected to the end face of the drive gear. The drive gear and the driven gear mesh with each other. The end face of the driven gear has a through hole, which is fixedly connected to the circumferential surface of the rotating shaft.

[0007] As a preferred embodiment of the new toy tractor head of this utility model, a small gear is fixedly connected to the end of the rotating shaft away from the drive motor and sleeved on the circumferential surface of the rotating shaft. The small gear meshes with a connecting gear, and a second gear meshes with the end of the connecting gear away from the drive motor.

[0008] As a preferred embodiment of the novel toy tractor head of this utility model, the second gear meshes with the first gear, the first gear is sleeved with the circumferential surface of the rotating shaft, and the connecting gear meshes with the third gear.

[0009] As a preferred embodiment of the new toy tractor head of this utility model, the third gear is fixedly connected to a fourth gear at one end near the drive motor, the fourth gear meshes with a fifth gear, and a connecting rod is fixedly connected to one end of the fifth gear near the first pulley, with the connecting rod being fixedly connected to the end face of the first pulley.

[0010] As a preferred embodiment of the new toy tractor head of this utility model, an assembled chimney is fixedly connected to both the left and right sides of the head.

[0011] The beneficial effects of this utility model are:

[0012] By driving a motor to engage the active and driven gears, which in turn drive the rollers via a rotating shaft, and then engage with a pinion, connecting gear, and other multi-gear transmissions, as well as a subsequent gear driving the pulley to rotate, the structure fully simulates the power transmission logic of a real tractor from the engine to the gearbox and then to the drive shaft. It restores the core characteristics of power transmission through multiple stages, avoiding the limitations of the simple design of a motor directly connecting to the wheels. It helps children understand the differences between different transmission forms and avoids the problem of only experiencing simple movement. It helps children learn about mechanical principles while playing, which is in line with the design goals of educational exploration toys. In addition, the mechanical damping generated by the multi-gear linkage can slow down the speed, making the driving speed suitable for children's driving ability, avoiding the situation of the vehicle being too fast or too slow in existing designs, and enhancing the fun and practicality of the toy.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a novel toy tractor head, including a body 1, a head 2 fixedly mounted on the front end of the body 1, two rollers 7 rotatably connected to the bottom end of the head 2 for driving the body 1 to move, the rollers 7 being distributed on the left and right sides of the head 2, a rotating shaft 6 fixedly connected to the opposite face of the two rollers 7 being rotatably connected inside the head 2, a drive assembly 20 for driving the rollers 7 to roll being mounted above the rotating shaft 6, a first pulley 16 being rotatably connected to the side of the head 2 near the rollers 7, a rotating belt 17 being rotatably connected to the circumferential surface of the first pulley 16, and a second pulley 18 being rotatably connected to the inner ring surface of the rotating belt 17.

[0022] The drive assembly 20 includes a drive motor 3, a drive gear 4, and a driven gear 5. The output end of the drive motor 3 is fixedly connected to the end face of the drive gear 4. The drive gear 4 and the driven gear 5 mesh with each other. The end face of the driven gear 5 has a through hole, which is fixedly connected to the circumferential surface of the rotating shaft 6.

[0023] During use, when a child presses the power switch on the front of the vehicle 2, the power switch is electrically connected to the drive motor 3 via a wire. The drive motor 3 is powered on and starts, and its output end drives the fixedly connected drive gear 4 to rotate counterclockwise. Because the drive gear 4 and the driven gear 5 mesh with each other, the drive gear 4 will drive the driven gear 5 to rotate clockwise synchronously. Also, because the through hole on the end face of the driven gear 5 is fixed with the circumference of the rotating shaft 6 by interference fit, the rotation of the driven gear 5 will drive the rotating shaft 6 to rotate together. The two ends of the rotating shaft 6 are fixedly connected to the rollers 7. Finally, the rotating shaft 6 drives the two rollers 7 to rotate synchronously, thereby driving the body 1 and the front of the vehicle 2 to move forward as a whole. If the drive motor 3 is reversed by controlling the switch, the front of the vehicle can be reversed, which can meet the flexible movement needs of children in indoor and outdoor scenarios.

[0024] During the rotation of the rotating shaft 6, the end away from the drive motor 3 will drive the fixedly sleeved pinion 8 to rotate synchronously. The pinion 8 meshes with the connecting gear 10, thereby driving the connecting gear 10 to rotate. The connecting gear 10 meshes with the second gear 11 and the third gear 12 at the same time, driving the second gear 11 and the third gear 12 to rotate respectively. The second gear 11 meshes with the first gear 9 sleeved on the rotating shaft 6, forming a multi-gear cooperative transmission structure. This multi-gear linkage design can reduce the rotation speed of the rotating shaft 6 through the mechanical damping of gear meshing, avoiding the problem of excessive speed caused by the drive motor 3 directly connecting to the wheel.

[0025] Example 2

[0026] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a small gear 8 that is sleeved on the circumferential surface of the rotating shaft 6 is fixedly connected to the end of the rotating shaft 6 away from the drive motor 3. The small gear 8 meshes with a connecting gear 10. The end of the connecting gear 10 away from the drive motor 3 meshes with a second gear 11.

[0027] The second gear 11 meshes with the first gear 9, the first gear 9 is sleeved with the circumferential surface of the rotating shaft 6, and the connecting gear 10 meshes with the third gear 12.

[0028] The third gear 12 is fixedly connected to the fourth gear 13 at one end near the drive motor 3. The fourth gear 13 meshes with the fifth gear 14. The fifth gear 14 is fixedly connected to the connecting rod 15 at one end near the first pulley 16. The connecting rod 15 is fixedly connected to the end face of the first pulley 16. The assembled chimneys 19 are fixedly connected to both sides of the front of the vehicle 2.

[0029] During use, in the above-mentioned multi-gear linkage process, the end of the third gear 12 near the drive motor 3 is welded and fixed to the fourth gear 13. When the third gear 12 rotates, it will drive the fourth gear 13 to rotate synchronously. The fourth gear 13 meshes with the fifth gear 14, thereby driving the fifth gear 14 to rotate. The end of the fifth gear 14 near the first pulley 16 is welded and fixed to the connecting rod 15, and the other end of the connecting rod 15 is welded and fixed to the end face of the first pulley 16. Therefore, the rotation of the fifth gear 14 will drive the connecting rod 15 and the first pulley 16 to rotate together. The first pulley 16 drives the second pulley 18 to rotate synchronously by rotating the belt 17. Finally, the complete linkage is achieved after the drive motor 3 starts, it drives the pulleys to rotate synchronously through multi-gear transmission.

[0030] The remaining structure is the same as that in Example 1.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
