Description

Technical Field

[0001] This invention relates to the field of children's vehicle device technology, specifically to a seat-driven horse-drawn carriage. Background Technology

[0002] Most children's bicycles on the market are currently pedal-driven or electric-driven. Pedal-driven bicycles require a higher level of leg strength and coordination from young children, while electric-driven bicycles suffer from high costs, limited use, and a lack of physical exercise. Furthermore, traditional children's bicycles offer limited interactive fun and are unlikely to sustain children's interest.

[0003] Therefore, there is an urgent need for a seat-driven children's vehicle that can provide a fun riding experience, is easy for young children to operate, and can also improve physical coordination. Summary of the Invention

[0004] (I) Technical Issues

[0005] The present invention provides a seat-driven carriage, which aims to solve the problems mentioned in the background art.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a seat-driven carriage, comprising an animal-shaped body, a steering mechanism located at the front of the body, and a set of wheels located at the rear of the body, and a seat-driven mechanism located in the middle of the body. The seat-driven mechanism includes a saddle that can move up and down, a transmission conversion component connected to the saddle, and a rear wheel drive assembly connecting the transmission conversion component and the set of wheels. The seat-driven mechanism converts the vertical linear motion of the saddle into the unidirectional rotational motion of the set of wheels through the transmission conversion component and the rear wheel drive assembly. The transmission conversion component includes a guide rail fixed inside the body, a rack slidably mounted on the guide rail, a retaining ring fixed inside the body, the bottom of the rack passing through the retaining ring and slidingly engaging with the retaining ring, a return spring sleeved at the bottom of the rack and above the retaining ring, a drive sprocket rotatably mounted inside the body, and a gear coaxially fixed on one side of the drive sprocket, the gear meshing with the rack.

[0008] Furthermore, the steering mechanism includes a steering handle, a front axle connected to the steering handle, and front wheels mounted at both ends of the front axle.

[0009] Furthermore, the wheel assembly includes a rear axle rotatably located at the rear bottom of the vehicle body, with rear wheels fixedly mounted at both ends of the rear axle.

[0010] Furthermore, the rear wheel drive assembly includes a passive sprocket rotatably disposed in the middle of the rear wheel axle, and a ratchet fixedly disposed on the rear wheel axle. A pawl adapted to the ratchet is installed on the side of the passive sprocket, and the passive sprocket is connected to the drive sprocket through a transmission chain.

[0011] Furthermore, the rack has a limiting structure at its bottom, and the lower end of the return spring contacts the retaining ring fixed inside the vehicle body while the upper end contacts the limiting structure.

[0012] Furthermore, foot pedals are symmetrically arranged on both sides of the vehicle body.

[0013] Furthermore, the animal form is that of a pony, and the vehicle body surface is decorated with simulated saddle textures and decorative parts.

[0014] (III) Technical Effects

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. The vehicle body is designed in the shape of a lively and adorable pony, with a beautiful appearance and novel structure that effectively attracts children's attention and interest. During the ride, children propel the vehicle forward by moving their bodies up and down, simulating the movements and rhythm of real horseback riding, bringing an immersive "galloping horseback" experience. Its entertainment and interactivity are significantly superior to traditional children's vehicles.

[0017] 2. The design utilizes a gear and rack mechanism to convert the linear motion of the saddle into rotational motion, thus changing the direction of force transmission. This results in a compact structure and high transmission efficiency. Simultaneously, a ratchet mechanism consisting of a ratchet and a pawl enables automatic clutch engagement during the driving process and allows for free-running during the reset phase, ensuring a smooth and natural riding experience without complex operations, making it especially suitable for young children.

[0018] 3. Abandoning the traditional pedal-driven method, it adopts a seat-driven method, allowing children to move the vehicle simply by shifting their body's center of gravity. This lowers the operating threshold and also trains their balance and coordination. The saddle automatically returns to its original position via a return spring, which acts as a buffer during the pressing and returning process, making the riding action smoother, less strenuous, and reducing children's fatigue.

[0025] Combined with appendix Figure 1 To be continued Figure 2 A seat-driven carriage includes an animal-shaped body 100, a steering mechanism at the front of the body 100, and a set of wheels at the rear of the body 100. It also includes a seat-driven mechanism located in the middle of the body 100. The seat-driven mechanism includes a saddle 1 that can move up and down, a transmission conversion component connected to the saddle 1, and a rear wheel drive assembly connecting the transmission conversion component and the set of wheels. The seat-driven mechanism converts the linear motion of the saddle 1 into the unidirectional rotational motion of the set of wheels through the transmission conversion component and the rear wheel drive assembly. The transmission conversion component includes a guide rail 2 fixed inside the body 100, a rack 11 slidably mounted on the guide rail 2, a retaining ring 6 fixed inside the body 100, the bottom of the rack 11 passing through and slidingly engaging with the retaining ring 6, a return spring 5 sleeved at the bottom of the rack 11 and above the retaining ring 6, a drive sprocket 4 rotatably mounted inside the body 100, and a gear 3 coaxially fixed on one side of the drive sprocket 4, the gear 3 meshing with the rack 11.

[0026] The steering mechanism includes a steering handle 101, a front axle connected to the steering handle 101, and front wheels 102 mounted on both ends of the front axle.

[0027] The walking wheel assembly includes a rear wheel axle 9 rotatably mounted on the rear side of the bottom of the vehicle body 100, with rear wheels 7 fixedly mounted at both ends of the rear wheel axle 9. The rear wheel drive assembly includes a passive sprocket 8 rotatably mounted in the middle of the rear wheel axle 9, and a ratchet 12 fixedly mounted on the rear wheel axle 9. A pawl 13 adapted to the ratchet 12 is mounted on the side of the passive sprocket 8. The passive sprocket 8 is connected to the drive sprocket 4 through a transmission chain 10.

[0028] The bottom of the rack 11 is provided with a limiting structure. The lower end of the return spring 5 contacts the retaining ring 6 fixed inside the vehicle body 100 and the upper end contacts the limiting structure. Stirrups 103 are symmetrically arranged on both sides of the vehicle body 100. The animal shape is a pony shape. The surface of the vehicle body 100 is provided with simulated saddle texture and decorative parts.

[0029] The core driving principle of this invention's horse-drawn carriage is to convert the up-and-down movement of a child's body (sitting motion) while riding into the unidirectional rotational movement of the rear wheel, thus achieving continuous forward movement without the need for pedals. Its power transmission path is as follows:

[0030] Seating and pressing action input: The child sits on the saddle 1 and uses his body weight to press down on the saddle 1. The saddle 1 drives the rack 11 to move downward along the guide rail 2.

[0031] Linear motion conversion: The rack 11 drives the gear 3 that meshes with it to rotate, and the gear 3 drives the coaxial fixed drive sprocket 4 to rotate.

[0032] Power transmission: The driving sprocket 4 drives the driven sprocket 8 to rotate through the transmission chain 10.

[0033] One-way drive: The passive sprocket 8 engages with the ratchet 12 fixed on the rear wheel axle 9 via the pawl 13 on its side, driving the rear wheel axle 9 and the rear wheel 7 to rotate forward.

[0034] Reset and Cyclic Operation: When the child gets up, the reset spring 5 pushes the rack 11 and saddle 1 to reset upwards; at this time, the passive sprocket 8 reverses, the pawl 13 slides past the ratchet 12, and does not drive the rear wheel axle 9, thus realizing unidirectional transmission.

[0035] The working process of this invention is as follows: The child straddles the saddle 1, places both feet on the footrests 103 on both sides of the vehicle body 100, and holds the steering handle 101 with both hands. The child uses his body weight to press down on the saddle 1, the saddle 1 drives the rack 11 to slide down along the guide rail 2, the rack 11 pushes the gear 3 to rotate, the gear 3 drives the drive sprocket 4 to rotate, the drive sprocket 4 transmits power to the driven sprocket 8 through the transmission chain 10. When the driven sprocket 8 rotates clockwise, the pawl 13 on its side engages with the ratchet 12, driving the rear wheel axle 9 and the rear wheel 7 to roll forward. The rolling of the rear wheel 7 pushes... The entire carriage 100 moves forward. Children can control the steering of the front wheel 102 through the steering handle 101 to adjust the direction of travel. When children lift their bodies, they reduce the pressure on the saddle 1. Under the elastic force of the return spring 5, the rack 11 slides upward along the guide rail 2 to return to its original position, causing the saddle 1 to rise. At this time, the gear 3 rotates in the opposite direction, the driven sprocket 8 rotates in the reverse direction, the pawl 13 disengages from the ratchet 12, and the rear wheel axle 9 does not rotate. By repeating the action of "pressing down and standing up", the saddle 1 can move up and down continuously, thereby driving the carriage to move forward continuously.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
