Description

Technical Field

[0001] This invention belongs to the field of scooter technology and relates to a toy scooter. Background Technology

[0002] Toy scooters are one of the most popular toys among children. People often need to carry scooters when going out, but some scooters nowadays cannot be folded, making them inconvenient to carry.

[0003] Patent document CN113799898A discloses a folding mechanism for a scooter, including a connecting seat, a frame, and a support shaft. During folding, the support rod is only locked when the front wheel support tube rotates to a certain angle. Before that, manual control is required to keep the support rod from rotating, preventing the handlebars at the end of the support rod from shifting and affecting the final folded state. If the handlebars shift during folding, they will end up in a tilted and locked position, increasing the scooter's footprint after folding and affecting its overall aesthetics.

[0004] To address the above problems, this invention proposes a toy scooter. Summary of the Invention

[0009] The connector includes a first connector and a second connector; the first connector is fixed on one side of the movable cylinder and slidably connected to the first slide rail; the second connector is fixed on the other side of the movable cylinder and slidably connected to the second slide rail.

[0010] Furthermore, the first connecting member includes a thin sleeve and a first limiting block; the thin sleeve is fixedly connected to one side of the movable cylinder, the thin sleeve is slidably engaged with the first slide rail, and the axis of the thin sleeve is parallel to the axis of the first slide rail; the cross section of the first limiting block is T-shaped, one end of the first limiting block is slidably connected to the thin sleeve, and the other end of the first limiting block is engaged with the first limiting groove; a tension spring is fixedly connected between the first limiting block and the bottom of the thin sleeve.

[0011] The second connecting component includes a coarse sleeve and a second limiting block. The coarse sleeve is fixedly installed on the other side of the movable cylinder and slides with the second slide rail. The axis of the coarse sleeve is parallel to the axis of the second slide rail. The cross-section of the second limiting block is T-shaped. One end of the second limiting block is slidably installed inside the coarse sleeve, and the other end of the second limiting block is engaged with the second limiting groove. A spring is fixedly connected between the second limiting block and the bottom of the coarse sleeve.

[0012] Furthermore, the first slide is an arc-shaped through groove, and the first limiting groove is distributed on the outer side of the end of the first fixed seat; the second slide is an arc-shaped groove with the opening facing the movable cylinder, and the second limiting groove is located on the side of the arc-shaped groove closer to the movable cylinder; a connecting component is fixedly connected between the first limiting block and the second limiting block, and the first limiting block drives the second limiting block to move through the connecting component.

[0013] Furthermore, the connector is a rope, and a threading channel is provided on the movable cylinder. One end of the threading channel is connected to the thin sleeve, and the other end of the threading channel is connected to the thick sleeve. The rope is slidably disposed in the threading channel.

[0014] Furthermore, the connecting component is a rope, and an annular groove is provided on the lower outer circumference of the second connecting rod.

[0018] Furthermore, a protective sleeve is fitted onto the hinge shaft.

[0019] Compared with existing technologies, the present invention has the following advantages: During the folding process, because the second connecting rod and the first connecting rod are not on a straight line, neither the second nor the first connecting rod can rotate, ensuring that the handlebars remain perpendicular to the length direction of the vehicle body, and the mounting base will not rotate unexpectedly. Therefore, the handlebars and mounting base can remain stable without the need for external assistance. This results in a scooter with good folding performance, stability, reliability, and ease of carrying.

[0020] The second connecting rod can only rotate around the hinge axis and fold when the handlebars are perpendicular to the length of the scooter body, that is, when the axis of the hinge axis and the axis of the slide are on the same straight line. This ensures that there is only one possible folded state. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1-6 As shown, the technical solution adopted by the present invention is as follows: A toy scooter includes a body 1, with a rear wheel 2 installed at the rear end of the body 1. A through hole is provided at the front end of the body 1, and a fixing cylinder 3 is fixedly connected to the front end of the body 1, the fixing cylinder 3 being coaxially located within the through hole. A first connecting rod 4 is coaxially rotatably connected within the fixing cylinder 3, and a mounting base is fixedly installed at the lower end of the first connecting rod 4, with a front wheel 5 rotatably installed within the mounting base.

[0035] A hinge seat is fixedly connected to the upper end of the first connecting rod 4, and a second connecting rod 6 is hinged to the hinge seat via a hinge shaft. The axis of the hinge shaft is perpendicular to the axis of the first connecting rod 4. A protective sleeve 9 is fitted onto the hinge shaft, with its upper end fixed to the movable cylinder 8 and its lower end fixed to the fixed cylinder 3. A handlebar 7 is fixedly connected to the upper end of the second connecting rod 6, and the length of the handlebar 7 is parallel to the axis of the hinge shaft.

[0036] When the first connecting rod 4 and the second connecting rod 6 are on the same straight line, the second connecting rod 6 can drive the first connecting rod 4 to rotate, thereby achieving steering of the front wheel 5. When the first connecting rod 4 and the second connecting rod 6 are not on the same straight line, neither the second connecting rod 6 nor the first connecting rod 4 can rotate, thus keeping the handlebars 7 and the front wheel 5 stable.

[0037] The lower part of the second connecting rod 6 is coaxially rotatably fitted with a movable cylinder 8. A fixing member is fixedly installed on the vehicle body 1, and an arc-shaped slide is opened on the fixing member. The axis of the slide is on the revolution plane of the hinge shaft rotating around the first connecting rod 4 and is perpendicular to the length direction of the vehicle body 1. The movable cylinder 8 is provided with a connecting member that cooperates with the slide, and both ends of the slide have limiting parts that lock the movable cylinder 8.

[0038] When the connector is at the upper end of the slide and engages with the limiting part, the scooter is in the unfolded state and locked, and can be used normally. When the connector is at the lower end of the slide and engages with the limiting part, the scooter is in the folded state and locked, making it easy to carry and preventing accidental opening.

[0039] Specifically, the fasteners include a first fixing seat 18 and a second fixing seat 21. Both the first fixing seat 18 and the second fixing seat 21 are fixedly mounted on the vehicle body 1. The first fixing seat 18 and the second fixing seat 21 are symmetrically arranged on both sides of the fixing cylinder 3.

[0040] The slide rail includes an arc-shaped first slide rail and an arc-shaped second slide rail. The limiting part includes a first limiting groove 20 and a second limiting groove 23. The first slide rail is formed on the first fixed base 18, and the first limiting groove 20 is formed at both ends of the first slide rail. The second slide rail is formed on the second fixed base 21, and the second limiting groove 23 is formed on both sides of the second slide rail. The axes of the first slide rail and the second slide rail are on the same straight line. In this embodiment, the first slide rail is an arc-shaped through groove 19, and the first limiting groove 20 is distributed on the outer side of the end of the first fixed base 18. The second slide rail is an arc-shaped groove 22 with the groove opening facing inward, that is, the groove opening of the arc-shaped groove 22 faces the movable cylinder 8, and the second limiting groove 23 is located on the side of the arc-shaped groove 22 closer to the movable cylinder 8.

[0041] As the hinge seat revolves around the axis of the first connecting rod 4, the angle between the axis of the hinge shaft and the axis of the slide changes with the revolution of the hinge shaft. Under the action of the first fixed seat 18 and the second fixed seat 21, when the axis of the hinge shaft and the axis of the slide are on the same straight line, the second connecting rod 6 can rotate around the hinge shaft. In this state, the scooter can be folded.

[0042] The connecting components include a first connecting component and a second connecting component. The first connecting component is fixed to one side of the movable cylinder 8 and slidably connected to the first slide rail. The second connecting component is fixed to the other side of the movable cylinder 8 and slidably connected to the second slide rail.

[0043] The first connecting component includes a thin sleeve 10 and a first limiting block 11. The thin sleeve 10 is fixedly connected to one side of the movable cylinder 8, and the thin sleeve 10 slides in fit with the arc-shaped through groove 19, with the axis of the thin sleeve 10 parallel to the axis of the first slide rail. The first limiting block 11 has a T-shaped cross-section, with one end of the first limiting block 11 slidingly connected to the thin sleeve 10 and the other end engaging with the first limiting groove 20. A handle 12 is fixedly provided on the outward-facing end of the first limiting block 11. A tension spring 13 is fixedly connected between the first limiting block 11 and the bottom of the thin sleeve 10. Under the action of the tension spring 13, the first limiting block 11 can be stably positioned within the first limiting groove 20, preventing the first limiting block 11 from accidentally sliding outward and causing the movable cylinder 8 to lose its limiting function.

[0044] The second connecting component includes a coarse sleeve 14 and a second limiting block 15. The coarse sleeve 14 is fixedly disposed on the other side of the movable cylinder 8 and slides with the arc-shaped groove 22, with the axis of the coarse sleeve 14 parallel to the axis of the second slide rail. The second limiting block 15 has a T-shaped cross-section, with one end of the second limiting block 15 slidingly disposed within the coarse sleeve 14 and the other end engaging with the second limiting groove 23. A spring 16 is fixedly connected between the second limiting block 15 and the bottom of the coarse sleeve 14. Under the action of the spring 16, the second limiting block 15 is stably positioned within the second limiting groove 23, preventing the second limiting block 15 from accidentally falling out of the second limiting groove 23.

[0045] When the first limiting block 11 is in the first limiting groove 20 and the second limiting block 15 is in the second limiting groove 23, the movable cylinder 8 is in a locked state, thereby preventing the second connecting rod 6 from being accidentally folded or unfolded.

[0046] The movable cylinder 8 has two threading channels arranged symmetrically about its axis. One end of each channel connects to the thin sleeve 10, and the other end connects to the thick sleeve 14. A rope 17 is slidably installed within each channel. One end of the rope 17 is fixedly connected to the first limiting block 11, and the other end is fixedly connected to the second limiting block 15. Pulling the handle 12 outward moves the first limiting block 11 outward, disengaging it from the first limiting groove 20, allowing the thin sleeve 10 to slide along the arc-shaped groove 19. Simultaneously, the first limiting block 11 pulls the second limiting block 15 via the rope 17, moving it closer to the movable cylinder 8 and disengaging it from the second limiting groove 23, allowing the thick sleeve 14 to slide along the arc-shaped groove 22. This releases the lock on the movable cylinder 8.

[0047] Working principle: In the initial state, the scooter is in normal use. The length direction of the handlebar 7 is perpendicular to the length direction of the scooter body 1. The tension spring 13 is in a stretched state, and under the action of the tension spring 13, the first limiting block 11 is located in the first limiting groove 20 at the upper end of the first fixed seat 18. The spring 16 is in a compressed state, and under the action of the spring 16, the second limiting block 15 is located in the second limiting groove 23 at the upper end of the first fixed seat 18. The rope 17 is in a taut state. At this time, the second connecting rod 6 and the first connecting rod 4 are on the same straight line.

[0048] When the scooter needs to turn, turn the handlebars 7 so that the handlebars 7 rotate around the axis of the second connecting rod 6. The second connecting rod 6 rotates relative to the movable cylinder 8. The second connecting rod 6 drives the first connecting rod 4 through the hinge seat so that the first connecting rod 4 rotates around the axis of the second connecting rod 6. This causes the mounting base and the front wheel 5 to rotate around the axis of the first connecting rod 4, thereby achieving the steering of the scooter.

[0049] When the scooter needs to be folded, first align the length of the handlebar 7 perpendicular to the length of the scooter body 1. Only when the axis of the hinge shaft and the axis of the slide are on the same straight line can the second connecting rod 6 rotate around the hinge shaft.

[0050] Pulling handle 12 outward causes the first limiting block 11 to slide outward against the spring force of tension spring 13, thereby disengaging the first limiting block 11 from the first limiting groove 20 at the upper end of the first fixed seat 18. Simultaneously, the first limiting block 11 pulls the second limiting block 15 via rope 17, causing the second limiting block 15 to move closer to the movable cylinder 8, disengaging it from the second limiting groove 23 at the upper end of the first fixed seat 18. Spring 16 is compressed. While holding handle 12 outward, the second connecting rod 6 rotates around the hinge axis towards the rear end of the vehicle body 1, causing the movable cylinder 8 to move synchronously. The thin sleeve 10 slides along the arc-shaped through groove 19 towards its lower end. The coarse sleeve 14 slides along the arc-shaped groove 22 towards its lower end. Until the thin sleeve 10 slides to the lower end of the arc-shaped through groove 19, and the coarse sleeve 14 slides to the lower end of the arc-shaped groove 22, at this time the first limiting block 11 is opposite to the first limiting groove 20 at the lower end of the arc-shaped through groove 19, and the second limiting block 15 is opposite to the second limiting groove 23 at the lower end of the arc-shaped groove 22.

[0051] Then, release the handle 12. Under the action of the tension spring 13, the first limiting block 11 moves into the thin sleeve 10 until it is engaged in the first limiting groove 20. Simultaneously, under the action of the spring 16, the second limiting block 15 moves into the thick sleeve 14 until it is engaged in the second limiting groove 23. At this point, the second connecting rod 6 is close to the vehicle body 1, and the scooter is in a folded and locked state, preventing accidental unfolding. Furthermore, the scooter is stable and reliable in the folded state and easy to carry.

[0052] When the scooter needs to be unfolded, pull the handle 12 outward to disengage the first limiting block 11 from the corresponding first limiting groove 20 and the second limiting block 15 from the corresponding second limiting groove 23, thereby causing the movable cylinder 8 to lose its limit. Then, the second connecting rod 6 and the movable cylinder 8 rotate upward around the hinge axis until the second connecting rod 6 returns to its initial state.

[0053] During the folding and unfolding process of the scooter, because the second connecting rod 6 and the first connecting rod 4 are not on a straight line, neither the second connecting rod 6 nor the first connecting rod 4 can rotate on its own. The handlebar 7 remains perpendicular to the length direction of the scooter body 1, and the mounting base will not rotate unexpectedly. This ensures that both the handlebar 7 and the mounting base remain stable. This results in a scooter with good folding performance, stability, reliability, and ease of carrying.

[0054] The second connecting rod 6 can only rotate around the hinge axis and fold when the handlebar 7 is perpendicular to the length of the vehicle body 1, that is, when the axis of the hinge axis and the axis of the slide are on the same straight line. Furthermore, both the handlebar 7 and the mounting base remain stable during the folding process, ensuring that there is only one folded state, i.e., the state with the best folding effect.

[0055] Example 2

[0056] This embodiment is an improvement on embodiment 1. Only the parts that are different from those in embodiment 1 are described here. All other parts are the same as those in embodiment 1.

[0057] like Figure 7 , Figure 8 As shown, an annular groove is formed on the lower outer circumference of the second connecting rod 6. The annular groove is coaxial with the second connecting rod 6 and is located inside the movable cylinder 8, creating a certain space between the second connecting rod 6 and the movable cylinder 8. One end of the rope 17 is fixedly connected to the first limiting block 11, and the other end of the rope 17 passes around the second connecting rod 6 and is fixedly connected to the second limiting block 15. The rope 17 slides against the side wall of the annular groove.

[0058] The sidewalls of the annular groove are smoothed to reduce the friction between the rope 17 and the annular groove. Thus, when the first limiting block 11 moves outward, the first limiting block 11 pulls the second limiting block 15 into the coarse sleeve 14 via the rope 17, and the rope 17 slides along the sidewalls of the annular groove, thereby making the rope 17 slide more smoothly.

[0059] Example 3

[0060] This embodiment is an improvement on embodiment 1. Only the parts that are different from those in embodiment 1 are described here. All other parts are the same as those in embodiment 1.

[0061] like Figure 9 , Figure 10 As shown, a clearance portion is provided at the lower part of the second connecting rod 6, extending radially through both sides of the second connecting rod 6. A connecting shaft 24 is fixedly connected between the first limiting block 11 and the second limiting block 15, passing through the clearance portion. Sliding holes are provided on both sides of the movable cylinder 8; one sliding hole connects the thin sleeve 10 to the clearance portion, and the other sliding hole connects the thick sleeve 14 to the clearance portion. The connecting shaft 24 slides through the sliding hole. The first limiting block 11 drives the second limiting block 15 to move in the same direction via the connecting shaft 24. When the scooter turns, even when the second connecting rod 6 rotates, it is limited by the connecting shaft 24, restricting its rotation angle and preventing it from rotating too much, thus avoiding the scooter tipping over. The turning angle of the scooter can be controlled according to the shape and structure design of the clearance portion.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
