Description

Technical Field

[0001] This utility model relates to the field of children's vehicle design technology, specifically to a children's vehicle drive mechanism and a children's four-wheeled vehicle. Background Technology

[0002] Strollers, as an indispensable piece of children's entertainment equipment in modern families, are favored by many families for their educational and entertaining features. Currently, commercially available strollers are mainly divided into two types: electric and manual, each with its own characteristics but also certain limitations.

[0003] Electric children's vehicles offer advantages such as ease of operation and high safety, requiring only simple controls for children to ride, making them highly entertaining. However, their highly automated operation also means that, on the one hand, the monotonous driving experience can easily lead to boredom in children, making it difficult to maintain their long-term interest; on the other hand, it neglects the importance of children exercising during play, failing to meet the needs of children's coordinated physical and intellectual development during their growth.

[0004] In contrast, traditional human-powered strollers (represented by chain drive) can provide a certain amount of exercise, but they still have their own limitations: for example, the efficiency of mechanical transmission is relatively low, especially when climbing hills or on complex road surfaces, children need to expend too much physical strength; maintenance is more frequent, and when riding outdoors, they are prone to absorbing pollutants and forming abrasive wear. Utility Model Content

[0005] In view of the deficiencies of the prior art described above, the technical problem to be solved by this utility model is to provide a children's vehicle drive mechanism and a children's four-wheeled vehicle that can maintain children's continuous interest in playing, promote their physical and mental development, and take into account both entertainment and education.

[0006] To achieve the above objectives, this utility model provides a children's vehicle drive mechanism. The children's vehicle includes a body and wheels. The children's vehicle drive mechanism includes a fixed rod, a pedal assembly, a crankshaft, and a connecting shaft. The fixed rod is fixedly mounted on the body. The pedal assembly includes a mounting bracket and a foot pedal. The mounting bracket is hinged to the fixed rod, and the foot pedal is connected to the mounting bracket. Two pedal assemblies are provided. The two ends of the crankshaft are respectively connected to the wheels. Two cranks are provided on the crankshaft. The two cranks are located in the same plane, and the two cranks have opposite directions of turning. Two connecting shafts are provided. One end of the connecting shaft is fixedly connected to the crank, and the other end is fixedly connected to the mounting bracket of the pedal assembly.

[0007] Furthermore, the foot pedal of the pedal assembly is hinged to the mounting bracket.

[0008] Furthermore, the foot pedal of the pedal assembly is provided with anti-slip texture.

[0009] Furthermore, the crankshaft is made of ductile iron.

[0010] This utility model also provides a children's four-wheeled vehicle, including the children's vehicle drive mechanism as described above.

[0011] As described above, the stroller drive mechanism of this utility model has the following beneficial effects:

[0012] By setting up a fixed rod, pedal assembly, crankshaft, and connecting shaft, stepping on the pedal drives the crankshaft to rotate via the mounting bracket and connecting shaft, thus propelling the children's vehicle. This provides a certain amount of movement to maintain children's continuous interest in play and promote their physical and intellectual development. While providing entertainment, it can also exercise children's motor coordination to a certain extent. Furthermore, the vehicle's drive mechanism has high transmission efficiency, allowing children to pass through steep inclines or complex road conditions without expending much physical effort. It also requires less maintenance and does not need frequent lubrication changes. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0020] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] See Figures 1 to 4 This utility model provides a children's stroller drive mechanism. The stroller includes a body 5 and wheels 6, with two front wheels and two rear wheels. The drive mechanism includes a fixed rod 1, a pedal assembly 2, a crankshaft 3, and a connecting shaft 4. The fixed rod 1 is fixedly mounted on the body 5, specifically located above the two front wheels. The pedal assembly 2 includes a mounting bracket 201 and a foot pedal 202. The mounting bracket 201 is hinged to the fixed rod 1, and the foot pedal 202 is connected to the mounting bracket 201. There are two pedal assemblies 2, specifically, the two pedal assemblies 2 are connected together. The crankshaft 3 is mounted on the fixed rod 1. The two ends of the crankshaft 3 are respectively connected to the wheels 6. Specifically, the two ends of the crankshaft 3 are respectively connected to the two rear wheels. The crankshaft 3 is provided with two cranks 301. The two cranks 301 are located in the same plane, that is, the two cranks 301 are set at 180° to each other, and the two cranks 301 have opposite directions of turning. That is, the working interval angle of the two cranks 301 is 180°. There are two connecting shafts 4. One end of the connecting shaft 4 is fixedly connected to the cranks 301, and the other end is fixedly connected to the mounting bracket 201 of the pedal assembly 2.

[0024] The basic working principle of the stroller drive mechanism involved in this utility model is as follows: In use, by setting a pedal assembly 2 on the fixed rod 1, when both feet alternately step on the pedal 202, the pedal 202 can drive the mounting frame 201 to rotate along the hinge point between the mounting frame 201 and the fixed rod 1. At the same time, the mounting frame 201 is connected to the crank 301 of the crankshaft 3 through the connecting shaft 4, so that the mounting frame 201 can drive the crankshaft 3 to rotate continuously through the connecting shaft 4, thereby driving the stroller. Specifically, when the pedal 202 drives the mounting frame 201 to rotate forward, that is, in the direction of the stroller's forward movement, the mounting frame 201 can drive the crankshaft 3 to rotate in the forward direction through the connecting shaft 4, thereby driving the stroller forward. When the pedal 202 drives the mounting frame 201 to rotate backward, that is, in the direction of the stroller's backward movement, the mounting frame 201 can drive the crankshaft 3 to rotate in the reverse direction through the connecting shaft 4, thereby driving the stroller backward movement.

[0025] See Figures 1 to 2 The present invention will be further described below with reference to a specific embodiment:

[0026] In this embodiment, see Figure 1 As a preferred design, the foot pedal 202 of the pedal assembly 2 is hinged to the mounting bracket 201, so that the foot pedal 202 is more in line with the human body's force exertion habits when stepping on it, and can reduce children's foot fatigue to a certain extent when stepping on it for a long time.

[0027] In this embodiment, see Figure 1 As a preferred design, the foot pedal 202 of the pedal assembly 2 is provided with anti-slip texture 203, which can increase the friction with the child's foot and prevent the foot from slipping off the pedal.

[0028] In this embodiment, see Figure 1 and Figure 2 As a preferred design, crankshaft 3 is made of ductile iron, which can improve the wear resistance, corrosion resistance, pressure resistance and fatigue resistance of crankshaft 3.

[0029] See Figures 3 to 4 This utility model also provides a children's four-wheeled vehicle, including the children's vehicle drive mechanism as described above.

[0030] As can be seen from the above, the children's vehicle drive mechanism of this utility model has the following beneficial effects:

[0031] By setting up a fixed rod 1, pedal assembly 2, crankshaft 3, and connecting shaft 4, stepping on the foot pedal 202 drives the crankshaft 3 to rotate via the mounting bracket 201 and connecting shaft 4, thereby driving the children's vehicle. Through a certain amount of movement, it maintains children's continuous interest in playing and promotes their physical and intellectual development. While providing entertainment, it can also exercise children's motor coordination to a certain extent. Furthermore, the transmission efficiency of the children's vehicle drive mechanism is high, and children do not need to exert much physical effort to pass through when facing uphill or complex road conditions. The maintenance requirements are low, and there is no need to change the lubricating oil frequently.

[0032] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
