Description

Technical Field

[0001] This utility model relates to the field of entertainment toy technology, specifically a speed-regulating travel device. Background Technology

[0002] A scooter (also known as a rocking scooter) is a recreational or exercise device propelled by the user swinging a handlebar. It is widely used in children's toys, fitness equipment, and other fields. Traditional scooters primarily rely on the user's left-right or twisting movements to drive the wheels in alternating motion, thus achieving forward movement or turning. However, existing scooters only control the movement of the front wheel, lacking coordination between the front and rear wheels, resulting in limited travel distance and failing to develop physical coordination, thus offering little enjoyment. Based on this, we propose a speed-adjustable propulsion device. Utility Model Content

[0003] The purpose of this utility model is to provide a speed-regulating travel device to overcome or at least partially solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a speed-regulating travel device, comprising a main rod, a seat disposed in the middle of the upper surface of the main rod, a handle rotatably connected to the front top of the main rod, and the bottom end of the handle extending out of the main rod, rotatable support frames disposed on both sides of the bottom of the main rod, one of the support frames being connected to the bottom end of the handle, one-way wheels disposed at both ends of the bottom of the support frame, and a linkage mechanism disposed between the two support frames, such that when the handle drives one support frame to swing, the other support frame can be driven to swing through the linkage mechanism.

[0005] In a preferred embodiment, the support frame has reserved holes on both sides of its top and a connecting groove on its side wall.

[0006] In a preferred embodiment, the linkage mechanism includes two connecting rods and a middle rod. One end of each of the two connecting rods is rotatably disposed in the connecting groove of the two support frames. The middle rod is rotatably disposed at the bottom center of the main rod, and its two ends are rotatably connected to the other ends of the two connecting rods. Multiple adjustment holes are provided on the connecting rods and the middle rod. The two connecting rods are located at diagonal positions of the two support frames.

[0007] In a preferred embodiment, one end of the connecting rod away from the support frame is rotatably connected to the side near the connection point between the other connecting rod and the intermediate rod.

[0008] In a preferred embodiment, the linkage mechanism includes a connecting rod, the two ends of which are rotatably connected to the connecting grooves of two support frames and are on the same side.

[0009] In a preferred embodiment, the linkage mechanism includes a connecting rod, the two ends of which are rotatably connected to the connecting slots of two support frames and are arranged diagonally.

[0010] Compared with the prior art, this utility model provides a speed-adjustable walking device. Through the design of different linkage mechanisms, the support frames on the front and rear sides can move synchronously or alternately, forming a movement mode similar to "walking with the same foot" or "alternating steps", making the walking process more dynamic and interesting. It is especially suitable for children's entertainment, increasing the duration and attractiveness of play. At the same time, using both feet to control the direction of movement and coordinating hands and feet improves body coordination. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this description, those skilled in the art can make creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This utility model provides a speed-regulating travel device, which solves the technical problems in the prior art. The overall concept is as follows:

[0021] Example 1

[0022] Please see Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a speed-regulating travel device. Specifically, it includes a main rod 1, a seat 2 disposed in the middle of the upper surface of the main rod 1, a handle 3 rotatably connected to the top front side of the main rod 1, and the bottom end of the handle 3 extending out of the main rod 1. Rotatable support frames 4 are disposed on both sides of the bottom of the main rod 1, and one of the support frames 4 is connected to the bottom end of the handle 3. One-way wheels 6 are disposed at both ends of the bottom of the support frame 4. A linkage mechanism is disposed between the two support frames 4. When the handle 3 drives one of the support frames 4 to swing, the other support frame 4 can be driven to swing through the linkage mechanism. In addition, in the actual production process, the entire car body can be decorated to improve the aesthetics and cover the linkage mechanism and other components, avoiding direct exposure.

[0023] Furthermore, the support frame 4 has pre-drilled holes 5 on both sides of its top, and connecting grooves 7 on its side walls.

[0024] In specific implementation, the linkage mechanism includes two connecting rods 8 and an intermediate rod 9. One end of each of the two connecting rods 8 is rotatably set in the connecting groove 7 of the two support frames 4. The intermediate rod 9 is rotatably set at the bottom center of the main rod 1, and its two ends are rotatably connected to the other ends of the two connecting rods 8. Multiple adjustment holes 10 are provided on the connecting rods 8 and the intermediate rod 9. The two connecting rods 8 are located at diagonal positions of the two support frames 4. The connection between the connecting rods 8 and the intermediate rod 9 and the support frames 4 is achieved by bolts 11 and nuts 12.

[0025] In summary, turning the handle 3 causes the front support frame 4 to swing. Under the action of the one-way wheel 6, its left end moves forward and its right end forms a stop. At this time, the linkage mechanism can be used to pull the rear support frame 4 to swing, with the left end of the rear support frame 4 moving forward and its right end forming a stop. When the handle 3 is turned in the opposite direction, the front support frame 4 swings, with its right end moving forward and its left end forming a stop. At the same time, the linkage mechanism pulls the rear support frame 4, causing its rear end to move forward and its left end to form a stop, so that the whole thing forms a clockwise motion. This alternation can be repeated to make the whole thing move.

[0026] Example 2

[0027] Please see Figure 3 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and embodiment 1 is that the connection position of one of the connecting rods 8 and the intermediate rod 9 has been changed. Specifically, the end of one of the connecting rods 8 away from the support frame 4 is rotatably connected to the side near the connection point of the other connecting rod 8 and the intermediate rod 9.

[0028] In summary, turning handle 3 moves the right side of the front support frame 4 forward and stops the left side, and through the linkage mechanism, it can pull the left side of the rear support frame 4 forward and stop the right side. Turning handle 3 in the opposite direction moves the left side of the front support frame 4 forward and stops the right side, and through the linkage mechanism, it can pull the left side of the rear support frame 4 forward and stop the right side. Overall, it forms the effect of "the right front leg taking a big step and the left rear leg following with a small step". By repeating this alternation, the whole thing can move.

[0029] Example 3

[0030] Please see Figure 5 This is the third embodiment of the present invention. The difference between this embodiment and the above embodiments is that a single connecting rod 8 is used to connect with the support frame 4. Specifically, the linkage mechanism includes a connecting rod 8, and the two ends of the connecting rod 8 are respectively rotatably connected to the connecting grooves 7 of the two support frames 4 and are on the same side.

[0031] In summary, turning handle 3 moves the right side of the front support frame 4 forward and stops it on the left. Through the linkage mechanism, the right side of the rear support frame 4 can be pulled forward and its left side stops. Turning handle 3 in the opposite direction makes the support frame 4 swing in the opposite direction, forming a clockwise effect. By repeating this alternation, the whole thing can be moved.

[0032] Example 4

[0033] Please see Figure 6 This is the fourth embodiment of the present invention. The difference between this embodiment and embodiment 3 is that the connection position of one end of the connecting rod 8 to one of the support frames 4 has been changed. Specifically, the linkage mechanism includes a connecting rod 8, and the two ends of the connecting rod 8 are respectively rotatably connected to the connecting grooves 7 of the two support frames 4 and are arranged diagonally.

[0034] In summary, turning handle 3 moves the right side of the front support frame 4 forward and stops the left side from moving backward. Through the linkage mechanism, the left side of the rear support frame 4 can be pulled forward and its right side is stopped. Turning handle 3 in the opposite direction makes the support frame 4 swing in the opposite direction, forming a state of "stepping forward with the right front foot and following with the left rear foot". Repeating this alternation allows the whole frame to move.

[0035] The above description of the embodiments is provided to facilitate understanding and use of the present invention by those skilled in the art. It is obvious to those skilled in the art that various modifications can be made to the embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, the present invention is not limited to the above embodiments. Any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
