Description

Technical Field

[0001] This utility model relates to the field of children's scooter technology, and in particular to a highly stable children's scooter with turning assist support. Background Technology

[0002] As a popular toy among children, the children's twist car has become a common tool for children's outdoor activities due to its flexible steering mechanism and fun. Traditional children's twist cars usually achieve steering by twisting the body. Its structure mainly includes basic components such as the body and wheels, and relies on the child's own center of gravity adjustment to control the steering angle and driving trajectory.

[0003] Currently, existing children's balance bikes are prone to significant tilting when turning due to centrifugal force. If the tilt angle is too large, the vehicle may overturn, posing a safety hazard, especially for children with weaker balance abilities, where the safety risk is even more prominent.

[0004] Therefore, we propose a highly stable children's scooter with cornering assist support. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Existing children's scooters are prone to significant lateral tilting due to centrifugal force when turning. If the tilt angle is too large, the vehicle may overturn, posing a safety hazard. This is especially true for children with weaker balance abilities, where the safety risks are even more pronounced.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A highly stable children's scooter with cornering assist support includes: a scooter body with multiple movable wheels at its bottom for movement; two mounting slots, each formed on one side wall of the scooter body; two mounting rotation components, each disposed inside the two mounting slots for rotation within the mounting slots; and two limiting components, each mounted outside the two mounting rotation components and located inside the two mounting slots, for limiting the rotation angle of the mounting rotation components.

[0008] Two hydraulic damping structures are installed inside the two mounting and rotating components. Each of their output ends is fixedly equipped with an abutment component. A compression spring is sleeved between the two abutment components and the two hydraulic damping structures. The abutment component is used to abut against the ground when the scooter body slides or turns. The compression spring and the hydraulic damping structure are used to retract and absorb energy after the abutment component makes contact.

[0009] As a preferred embodiment of this utility model, the mounting rotation assembly includes:

[0010] A first rotating rod and a mounting block, wherein the mounting block is rotatably connected inside the mounting groove via the first rotating rod.

[0011] As a preferred embodiment of this utility model, the limiting component includes:

[0012] First limiting plate and second limiting plate;

[0013] The first limiting plate is fixedly disposed inside the mounting groove and near the bottom, and is used to limit the downward direction of the mounting rotating component to prevent the scooter body from contacting the ground when it moves.

[0014] The second limiting plate is fixedly disposed inside the mounting groove and near the top, and is used to limit the upward movement direction of the mounting rotating assembly to prevent the mounting rotating assembly from swinging excessively upward and causing it to tip over when it is subjected to resistance.

[0015] As a preferred embodiment of this utility model, the hydraulic damping structure includes:

[0016] The outer cylinder has an outer cavity inside it;

[0017] An inner cylinder is disposed inside the outer cavity, and its top is fixedly connected to the outer cylinder;

[0018] The inner cavity is formed inside the inner cylinder;

[0019] A hole is formed at the bottom of the inner cylinder to connect the inner cavity with the outer cavity.

[0020] As a preferred embodiment of this utility model, the hydraulic damping structure further includes:

[0021] A push rod, one end of which is connected to the abutment assembly;

[0022] A connecting rod is fixedly installed at the bottom of the top rod;

[0023] The piston is fixedly mounted at the bottom of the connecting rod;

[0024] Several through holes are equidistantly spaced around the piston.

[0025] As a preferred embodiment of this utility model, the abutting component includes:

[0026] The mounting bracket is fixedly installed at the bottom of the top rod;

[0027] The second rotating rod is rotatably connected inside the mounting bracket;

[0028] The abutment block is fixedly mounted on the second rotating rod.

[0029] As a preferred embodiment of this utility model, the abutting component is used to adjust the abutting position by rotating the abutting block on the second rotating rod when it is in contact with the ground;

[0030] A compression spring is installed between the mounting bracket and the outer cylinder, and the compression spring is used to retract and absorb energy when the abutment assembly comes into contact with the abutment assembly.

[0031] Both the inner and outer cavities are filled with oil. The push rod is used to press down synchronously when the compression spring retracts, driving the connecting rod and piston to press down, so that the oil can pass through several through holes at the piston, and the oil that does not pass through is squeezed into the outer cavity through the holes.

[0032] Compared with the prior art, the beneficial effects of this utility model are:

[0033] In this invention, a limiting component is set in the mounting groove. The first limiting plate limits the downward direction of the mounting rotating component, preventing the support structure from contacting the ground and affecting movement during normal driving. The second limiting plate limits the upward direction of the mounting rotating component, which can limit excessive lateral sway of the vehicle body when turning and effectively control the tilt angle. This reduces the risk of vehicle rollover from a mechanical structure perspective, and significantly improves safety, especially for children with weak balance.

[0034] The combined design of the hydraulic damping structure and compression spring allows the scooter to contact the ground through the abutment component when it sideslips or turns. The compression spring first provides initial elastic cushioning, and simultaneously drives the push rod to press down the piston inside the hydraulic damping structure, allowing the oil to flow between the inner and outer cavities through the through holes and orifices. The liquid damping effect is used to absorb impact energy and prevent the scooter from being subjected to hard impacts. This structure can respond quickly to tilting actions and prolong the energy release process through hydraulic cushioning, reducing the swaying of the scooter caused by excessive impact force and improving driving stability.

[0035] The contact component is rotatably connected to the mounting frame via the second rotating rod, allowing the contact block to adaptively adjust the contact angle when in contact with the ground, adapting to different tilt angles of turning scenarios or uneven road surfaces, and avoiding local stress concentration caused by uneven support surfaces.

[0047] Example

[0048] like Figure 1-6 As shown, this utility model provides a technical solution: a highly stable children's scooter with turning assist support, including a scooter body 10, the bottom of which has multiple moving wheels for movement; two mounting slots 20, both opened on the side walls of the scooter body 10; two mounting rotation components 40, both disposed inside the two mounting slots 20, for rotation within the mounting slots 20; two limiting components 30, both installed outside the two mounting rotation components 40 and located inside the two mounting slots 20, for limiting the rotation angle of the mounting rotation components 40; two hydraulic damping structures 50, both installed inside the two mounting rotation components 40, each with a fixed abutment component 60 at its output end, and a compression spring 70 sleeved between the two abutment components 60 and the two hydraulic damping structures 50. The abutment components 60 are used to abut against the ground when the scooter body 10 slides sideways or turns, and the compression springs 70 and hydraulic damping structures 50 are used to retract and absorb energy after the abutment components 60 abut.

[0049] When the scooter body 10 is in normal motion, the bottom of the mounting rotating component 40 contacts the second limiting plate 302 near the bottom of the mounting groove 20, raising the hydraulic damping structure 50 and the abutment component 60 and keeping them at a distance from the ground, thus not affecting the movement of the wheels. When the vehicle turns or sideslips, causing the body to tilt, the mounting rotating component 40 rotates upward around the first rotating rod 401, causing the hydraulic damping structure 50 and the abutment component 60 to move upward synchronously with the mounting rotating component 40, at which point the distance between the abutment component 60 and the ground decreases. When the body tilts to the point that the abutment component 60 contacts the ground, the ground reaction force compresses the spring 70 and the hydraulic damping structure 50 upward through the abutment component 60, and the hydraulic damping structure 50 absorbs the impact energy through the internal oil flow. At the same time, the mounting rotating component 40 moves upward to contact the first limiting plate 301 near the top of the mounting groove 20, limiting the rotation angle and preventing excessive body tilt. The synergistic effect of "mounting rotation + angle limiting + buffer energy absorption" improves turning stability.

[0050] The mounting of the rotating assembly 40 includes:

[0051] The first rotating rod 401 and the mounting block 402 are rotatably connected to the inside of the mounting groove 20 via the first rotating rod 401.

[0052] Mounting block 402 rotates within mounting groove 20 around the first rotating rod 401. Under normal conditions, the bottom of mounting block 402 is pressed against the second limiting plate 302 near the bottom of mounting groove by gravity, keeping mounting block 402 stable. Hydraulic damping structure 50 and contact assembly 60 are fixed within mounting groove 20 by mounting block 402 and maintain a safe distance from the ground. When the vehicle body tilts, the ground applies an upward reaction force to mounting block 402 through contact assembly 60. Mounting block 402 rotates upward around the first rotating rod 401 until it is blocked by the first limiting plate 301 near the top of mounting groove. At this time, contact assembly 60 contacts the ground and provides support. When the vehicle body returns to normal, mounting block 402 rotates downward around the first rotating rod 401 under the restoring force of compression spring 70 and its own gravity, re-contacting the second limiting plate 302, thus restoring the support structure.

[0053] Limiting component 30 includes:

[0054] First limiting plate 301 and second limiting plate 302;

[0055] The second limiting plate 302 is fixedly installed inside the mounting groove 20 and near the bottom to limit the downward direction of the mounting rotating component 40 and prevent the scooter body 10 from contacting the ground when it moves.

[0056] The first limiting plate 301 is fixedly installed inside the mounting groove 20 and near the top, and is used to limit the upward movement of the mounting rotating component 40 to prevent the mounting rotating component 40 from swinging too upward and tipping over when it is resisted.

[0057] During normal driving, the rotating assembly 40 hangs down naturally due to gravity, and its bottom abuts against the second limiting plate 302 at the bottom of the mounting groove, ensuring that the hydraulic damping structure 50 and the contact assembly 60 maintain a safe gap with the ground and do not interfere with the rolling of the moving wheel. When turning and tilting, the rotating assembly 40 rotates upward due to the reaction force of the ground, and its top abuts against the first limiting plate 301 at the top of the mounting groove. The rotation angle is limited within a safe range by mechanical limiting, preventing the rotating assembly 40 from swinging too much upward and causing excessive shift of the vehicle's center of gravity, thus achieving two-way control of "sag limit to prevent ground contact and swing limit to prevent rollover".

[0058] The hydraulic damping structure 50 includes:

[0059] The outer cylinder 501 has an outer cavity 502 inside it;

[0060] The inner cylinder 503 is disposed inside the outer cavity 502, and its top is fixedly connected to the outer cylinder 501;

[0061] The inner cavity 504 is located inside the inner cylinder 503;

[0062] Hole 505 is formed at the bottom of inner cylinder 503 and is used to connect inner cavity 504 with outer cavity 502.

[0063] The outer cavity 502 formed by the outer cylinder 501 and the inner cylinder 503, and the inner cavity 504 of the inner cylinder 503 are both filled with oil. When the contact component 60 is squeezed upward by the ground reaction force, the push rod 506 drives the connecting rod 507 and the piston 508 to move downward. The oil in the inner cavity 504 flows into the outer cavity 502 through the hole 505. The flow of oil generates damping force to absorb the impact energy. When the impact force disappears, the compression spring 70 pushes the contact component 60 to reset, and the oil flows back to the inner cavity 504 through the hole 505. The buffering and energy absorption cycle is achieved by utilizing the liquid damping effect.

[0064] The hydraulic damping structure 50 also includes:

[0065] The push rod 506 has one end connected to the abutment assembly 60;

[0066] The connecting rod 507 is fixedly installed at the bottom of the top rod 506;

[0067] Piston 508 is fixedly mounted at the bottom of connecting rod 507;

[0068] Several through holes 509 are equidistantly arranged around the piston 508.

[0069] When the contact component 60 contacts the ground, the push rod 506 is pushed upward, causing the connecting rod 507 and the piston 508 to move downward in the inner cavity 504 of the inner cylinder 503. The piston 508 squeezes the oil in the inner cavity 504. Part of the oil flows down to the bottom of the piston 508 through the through hole 509, and the other part of the oil is squeezed to the outer cavity 502 through the hole 505. When the oil flows through the through hole 509 and the hole 505, it generates damping resistance, which slows down the downward movement speed of the piston 508, converts the impact force into the heat energy of the oil flow, avoids the vehicle body from being subjected to hard impact, and realizes hydraulic buffer energy absorption.

[0070] The contact component 60 includes:

[0071] Mounting bracket 601 is fixedly installed at the bottom of top rod 506;

[0072] The second rotating rod 603 is rotatably connected inside the mounting bracket 601;

[0073] The abutment block 602 is fixedly mounted on the second rotating rod 603.

[0074] The abutment block 602 is rotatably connected to the mounting frame 601 via the second rotating rod 603. When the abutment block 602 contacts the ground, if the ground is tilted or uneven, the abutment block 602 can rotate around the second rotating rod 603 to adaptively adjust the abutment angle, so that the abutment block 602 keeps in contact with the ground and ensures uniform support force. At the same time, the mounting frame 601 drives the top rod 506 to compress the compression spring 70 upward and pushes the hydraulic damping structure 50 to work. Through the dual effects of rotation adjustment and damping buffer, the support stability and road surface adaptability are improved.

[0075] The abutting component 60 is used to adjust the abutting position by rotating the abutting block 602 on the second rotating rod 603 when it is in contact with the ground;

[0076] A compression spring 70 is installed between the mounting bracket 601 and the outer cylinder 501. The compression spring 70 is used to retract and absorb energy when the abutment assembly 60 is in contact with the abutment assembly.

[0077] Both the inner cavity 504 and the outer cavity 502 are filled with oil. The push rod 506 is used to press down synchronously when the compression spring 70 retracts, driving the connecting rod 507 and the piston 508 to press down, so that the oil can pass through several through holes 509 at the piston 508, and squeeze the oil that does not pass through through the hole 505 into the outer cavity 502.

[0078] When the scooter tilts and the contact block 602 touches the ground, the contact block 602 first rotates and contacts the ground via the second rotating rod 603. Then, the compression spring 70 is compressed by the mounting bracket 601 to generate elastic buffering force. At the same time, the push rod 506 moves down to push the piston 508. The oil in the inner cavity 504 flows into the outer cavity 502 through the through hole 509 and the hole 505, using liquid damping to consume the impact energy. When the scooter returns to its upright position, the compression spring 70 resets and pushes the mounting bracket 601 up. The push rod 506 drives the piston 508 up. The oil in the outer cavity 502 flows back to the inner cavity 504 through the hole 505. The through hole 509 limits the oil return speed, forming a slow reset process. This avoids the support structure from bouncing up quickly and causing the scooter to shake, thus achieving a complete working cycle of "contact-adjustment-buffering-energy absorption-reset".

[0079] Workflow

[0080] I. Normal Driving Condition

[0081] Initial position: The bottom of the rotating assembly 40 contacts the second limiting plate 302 near the bottom of the mounting groove 20, and the hydraulic damping structure 50 and the abutment assembly 60 are raised and kept at a safe distance from the ground.

[0082] Functionality maintained: The scooter body 10 moves normally via the bottom moving wheels, and the support structure is stored in the mounting slot 20 without interfering with driving.

[0083] II. Turning / Skipping Trigger Process

[0084] Vehicle body roll: When the vehicle turns or skids, the center of gravity of the vehicle body shifts, causing body roll. The rotating assembly 40 is installed and rotates upward around the first rotating rod 401 as the axis.

[0085] Contact with the ground: After the rotating assembly 40 is moved upward, the distance between the contact assembly 60 and the ground decreases until the contact block 602 contacts the ground.

[0086] III. Support and Buffer Mechanism

[0087] Adaptive adjustment: The abutment block 602 rotates via the second rotating rod 603 to automatically adjust its angle to fit the uneven ground and ensure the stability of the support point.

[0088] Multi-stage buffer energy absorption:

[0089] Compression spring 70: The contact component 60 is pressed upward by the reaction force of the ground, and the compression spring 70 initially buffers the impact.

[0090] Hydraulic damping structure 50: The push rod 506 drives the piston 508 to move down, and the oil in the inner cavity 504 flows into the outer cavity 502 through the through hole 509 and the hole 505. The liquid damping consumes energy and reduces the impact speed.

[0091] Angle limit: The rotating assembly 40 is moved upward to contact the first limiting plate 301 near the top of the mounting slot 20, limiting the maximum rotation angle and preventing the vehicle body from overturning.

[0092] IV. Recovery Process

[0093] Elastic reset: After the vehicle body is straightened, the compression spring 70 pushes the abutment component 60 downward to reset, and the oil flows back to the inner cavity 504 through the hole 505.

[0094] Storage and locking: The rotating assembly 40 rotates downward around the first rotating rod 401 under the action of gravity, and re-contacts the second limiting plate 302, and the support structure returns to its initial storage state.

[0095] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
