An electrically powered balance car

Abstract

This utility model relates to an electric self-balancing scooter, solving the problem of excessive or insufficient rotation amplitude in existing technologies. The technical solution includes a frame, wheels, and pedal components. The frame includes a fixed shaft and a rotating shaft sleeved on the fixed shaft. A first rotation limiting structure is provided between each rotating shaft and the fixed shaft. Two sets of pedal components are correspondingly mounted on the rotating shafts. When a force is applied to the front or rear side of the pedal component, the pedal component drives the rotating shaft to rotate forward or backward. The rotation limiting structure limits the rotation amplitude of the pedal component. Its effect is that the rotation limiting structure forms a stable mechanical limiting structure, ensuring stable forward or backward rotation amplitude of the pedal component, avoiding excessive or insufficient rotation amplitude. This allows the self-balancing scooter to move forward, backward, or turn at appropriate speeds, while ensuring a safe turning radius. This improves both the user experience and safety of the self-balancing scooter.

Description

Technical Field

[0001] This utility model relates to the field of self-balancing scooters, and more particularly to an electric self-balancing scooter. Background Technology

[0002] Existing self-balancing scooters mainly include integrated self-balancing scooters and twist-type self-balancing scooters. Twist-type self-balancing scooters include a first main body and a second main body arranged rotatably relative to each other, with two wheels respectively mounted on the first and second main bodies (equivalent to the pedal assembly involved in this invention), or the two main bodies are rotatably mounted on the same axle, with the two wheels fixed at both ends of the axle. Integrated self-balancing scooters include a support frame that cannot rotate relative to each other, with two wheels mounted on the support frame, and a pedal (equivalent to the pedal assembly involved in this invention) that can rotate relative to the support frame. These existing self-balancing scooters control forward, backward, or turning movements by triggering a control module through the rotation of the first and second main bodies or the pedal.

[0003] However, the control module is prone to control errors or malfunctions, causing the first and second main bodies or the pedals (i.e., the pedal assembly) to tilt forward or backward (i.e., the rotation range) to be too large or too small. When the rotation range is too small, it affects the forward, backward, or turning performance (e.g., insufficient speed, insufficient distance, excessive turning angle, incomplete turning, etc.). When the rotation range is too large, it results in excessively fast forward or backward speed, excessive distance, or excessively small turning angle, or over-turning. This not only affects the user experience but also easily creates safety hazards. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned problems existing in the prior art and provide a self-balancing scooter. By forming a stable mechanical limiting structure through a rotation limiting structure (including a first rotation limiting structure and a second rotation limiting structure), the pedal component can rotate forward or backward with a stable amplitude, avoiding the occurrence of excessive or insufficient rotation amplitude. This allows the self-balancing scooter to move forward, backward, or turn at a suitable speed, and can ensure the turning amplitude. This not only improves the user experience of the self-balancing scooter, but also improves its safety.

[0005] The above-mentioned technical objective of this utility model is mainly achieved through the following technical solution: an electric balance vehicle, including a frame, wheels disposed at both ends of the frame, and two sets of pedal components disposed on the frame. The frame includes a fixed shaft and at least two rotating shafts sleeved on the fixed shaft. A first rotation limiting structure is provided between each rotating shaft and the fixed shaft. The two sets of pedal components are respectively disposed on the rotating shafts one to one. When the front or rear side of the pedal component is subjected to a force, the pedal component drives the rotating shaft to rotate forward or backward. The rotation limiting structure is used to limit the rotation amplitude of the pedal component.

[0006] The difference between this technical solution and the prior art is that a first rotation limiting structure is set between the rotating shaft and the fixed shaft. A stable mechanical limiting structure is formed by the first rotation limiting structure (preferably also by a second rotation limiting structure), so that the forward or backward rotation amplitude of the pedal component is stable, avoiding the situation of excessive or insufficient rotation amplitude. This allows the balance vehicle to move forward, backward or turn at a suitable speed, and can ensure the turning amplitude, which is beneficial to improving the user experience of the balance vehicle and also to improving the safety of use.

[0007] As a further improvement and supplement to the above technical solution, this utility model adopts the following technical measures: The first rotation limiting structure includes a first through hole, a first oblong hole extending in the circumferential direction, and a limiting connector. The first oblong hole is disposed on the fixed shaft or the rotating shaft. The limiting connector passes through the first through hole and the first oblong hole. The outer end of the limiting connector is fixed to the pedal assembly, and the inner end of the limiting connector is limited within the inner cavity of the fixed shaft. The first oblong hole is provided to limit the forward or backward rotation of the pedal assembly by the length of the first oblong hole, thereby realizing the function of the first rotation limiting structure.

[0008] Preferably, to further improve the reliability of the rotation limiting structure, the frame also includes at least two bushings fitted onto the fixed shaft, with each of the two rotating shafts correspondingly fitted onto a bushing. Both bushings are equipped with a second rotation limiting structure. The bushings improve the forward and backward rotation flexibility of the pedal assembly, reduce wear between the fixed and rotating shafts, and extend service life. The second rotation limiting structure is adapted to the first rotation limiting structure, allowing both structures to work together to limit the movement of the pedal assembly.

[0009] Preferably, the second rotation limiting structure includes a second oblong hole or a second through hole. When the fixed shaft is provided with a first oblong hole, the bushing is provided with a second through hole, and the limiting connector on the first rotation limiting structure passes through the first oblong hole, the second through hole, and the first through hole. When the fixed shaft is provided with a first through hole, the bushing is provided with a second oblong hole, and the limiting connector on the first rotation limiting structure passes through the first through hole, the second oblong hole, and the first oblong hole.

[0010] Preferably, the circumferential lengths of the first and second waist-shaped holes are adapted to the amplitude of the forward and backward rotation of the pedal assembly.

[0011] Preferably, the rotating shaft is connected to the corresponding pedal assembly via a second connector, so that the pedal assembly is fixed on the rotating shaft.

[0012] Preferably, the mounting shaft of the wheel is inserted into the inner cavity of the rotating shaft, and the mounting shaft of the wheel is detachably connected to the corresponding rotating shaft through a third connector.

[0013] Preferably, a fourth connector is provided between the mounting shaft, the rotating shaft and the corresponding pedal assembly to enhance the connection stability of the pedal assembly.

[0014] Preferably, each set of pedal components is provided with a functional seat below it, the vehicle frame is disposed between the pedal components and the functional seats, the functional seats are fixed to the bottom of the pedal components by detachable fasteners, each set of functional seats is provided with a functional cavity, the functional cavity is provided with an electric control component, the electric control component is used to control the movement of the vehicle.

[0015] Preferably, a light-emitting component is provided between the pedal assembly and the functional seat. The light-emitting component is electrically connected to the electric control assembly and connected by control signals. The parts of the pedal assembly and the functional seat corresponding to the light-emitting component are unidirectional light-transmitting parts.

[0016] The beneficial effects of this utility model are as follows: 1. A stable mechanical limiting structure is formed by the rotation limiting structure (including the first rotation limiting structure and the second rotation limiting structure), which ensures that the forward or backward rotation amplitude of the pedal component is stable, avoiding excessive or insufficient rotation amplitude. This allows the balance scooter to move forward, backward, or turn at a suitable speed, and ensures the turning amplitude, which not only improves the user experience of the balance scooter but also enhances its safety. 2. The electric control component improves the automatic control performance of the balance scooter and its balance performance, thereby improving safety and reliability, and making it easier for beginners to quickly master the operation. 3. The light-emitting component not only improves the viewing angle and increases the fun of use but also makes the balance scooter's location more noticeable, allowing others to see it promptly and reducing the possibility of accidental collisions, thus improving the personal safety of the user and others.

Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example: Figures 1-5 As shown, an electric self-balancing scooter includes a frame 1, wheels 2 disposed at both ends of the frame 1, and two sets of pedal components 3 disposed on the frame 1.

[0024] The difference between this technical solution and the prior art is that: the frame 1 includes a fixed shaft 4 and at least two rotating shafts 5 sleeved on the fixed shaft 4. A first rotation limiting structure is provided between each rotating shaft 5 and the fixed shaft 4. The two sets of pedal components 3 are respectively and correspondingly arranged on the rotating shafts 5. When the front or rear side of the pedal component 3 is subjected to force, the pedal component 3 drives the rotating shaft 5 to rotate forward or backward. The rotation limiting structure is used to limit the rotation range of the pedal component 3.

[0025] In this technical solution, a first rotation limiting structure is provided between the rotating shaft 5 and the fixed shaft 4. The first rotation limiting structure (preferably also a second rotation limiting structure) forms a stable mechanical limiting structure, which makes the forward or backward rotation amplitude of the pedal component 3 stable, avoiding the situation of excessive or insufficient rotation amplitude. This allows the balance vehicle to move forward, backward or turn at a suitable speed, and ensures the turning amplitude, which not only improves the user experience of the balance vehicle, but also improves the safety of use.

[0026] Next, we will further refine and elaborate on the above technical solution: In practical applications, the first rotation limiting structure includes a first through hole 6, a first waist-shaped hole 7 extending in the circumferential direction, and a limiting connector 8. The first waist-shaped hole 7 is provided on the fixed shaft 4 or the rotating shaft 5. The limiting connector 8 passes through the first through hole 6 and the first waist-shaped hole 7. The outer end of the limiting connector 8 is fixed to the pedal assembly 3, and the inner end of the limiting connector 8 is limited in the inner cavity of the fixed shaft 4.

[0027] For this technical solution, the first rotation limiting structure includes two technical solutions with equivalent technical effects: The first technical solution is: the first waist-shaped hole 7 is provided on the fixed shaft 4, and the first through hole 6 is provided on the rotating shaft 5; The second technical solution is: the first waist-shaped hole 7 is provided on the rotating shaft 5, and the first through hole 6 is provided on the fixed shaft 4.

[0028] In practical applications, the second technical solution is the preferred solution.

[0029] The first waist-shaped hole 7 is designed to limit the forward or backward rotation of the pedal assembly 3 by the length of the first waist-shaped hole 7, thereby realizing the function of the first rotation limit structure.

[0030] In practical applications, in order to further improve the reliability of the rotation limiting structure, the frame 1 also includes at least two bushings 9 sleeved on the fixed shaft 4, and the two rotating shafts 5 are respectively sleeved on the bushings 9. Both bushings 9 are provided with a second rotation limiting structure.

[0031] In practical applications, the second rotation limiting structure includes a second oblong hole 10 or a second through hole. When the fixed shaft 4 is provided with a first oblong hole 7, the bushing 9 is provided with a second through hole, and the limiting connector 8 on the first rotation limiting structure passes through the first oblong hole 7, the second through hole, and the first through hole 6. When the fixed shaft 4 is provided with a first through hole 6, the bushing 9 is provided with a second oblong hole 10, and the limiting connector 8 on the first rotation limiting structure passes through the first through hole 6, the second oblong hole 10, and the first oblong hole 7.

[0032] For this technical solution, the first rotation limiting structure combined with the second rotation limiting structure forms the following two technical solutions with equivalent technical effects. The first technical solution is: a first waist-shaped hole 7 is provided on the fixed shaft 4, a first through hole 6 is provided on the rotating shaft, and a second through hole is provided on the bushing 9; The second technical solution is as follows: the first through hole 6 is provided on the fixed shaft 4, the first waist-shaped hole 7 is provided on the rotating shaft 5, and the second waist-shaped hole 10 is provided on the rotating shaft 5.

[0033] In practical applications, the second technical solution is the preferred solution.

[0034] In practical applications, the circumferential lengths of the first waist-shaped hole 7 and the second waist-shaped hole 10 are adapted to the forward and backward rotation amplitude of the pedal assembly 3.

[0035] In practical applications, the rotating shaft 5 is connected to the corresponding pedal assembly 3 via the second connector 11, so that the pedal assembly 3 is fixed on the rotating shaft 5.

[0036] In practical applications, the mounting shaft 12 of the wheel 2 is inserted into the inner cavity of the rotating shaft 5, and the mounting shaft 12 of the wheel 2 is detachably connected to the corresponding rotating shaft 5 through the third connector 13.

[0037] In practical applications, a fourth connector 14 is provided between the mounting shaft 12, the rotating shaft 5 and the corresponding pedal assembly 3 to enhance the connection stability of the pedal assembly 3.

[0038] In practical applications, a functional seat 15 is provided below each set of pedal components 3. The frame 1 is located between the pedal components 3 and the functional seat 15. The functional seat 15 is fixed to the bottom of the pedal components 3 by detachable fasteners. Each set of functional seats 15 is provided with a functional cavity. An electric control component 16 (hereinafter referred to as the control component) is provided in the functional cavity. The electric control component 16 is used to control the movement of the vehicle.

[0039] In this technical solution, the electric control component 16 improves the automatic control performance of the self-balancing scooter. The control component includes a sensing module, a control module electrically and signal-connected to the sensing module (or a sensing module is installed on the control module), and a first sensing switch on the pedal component 3. When a user steps on the pedal component 3, the first sensing switch and the sensing module generate a first sensing signal. The control module receives the first sensing signal and can determine that the user is standing on the self-balancing scooter, and control the scooter to enter a balanced state. When the user applies force to the front or rear of the pedal component 3, the pedal component 3 tilts forward or backward, the first sensing switch and the sensing module generate a second sensing signal, and the control module receives the second sensing signal and controls the wheels 2 to move.

[0040] In practical applications, a light-emitting component 17 is disposed between the foot pedal assembly 3 and the functional seat 15. The light-emitting component 17 is electrically connected and controlled by the electric control assembly 16. The portions of the foot pedal assembly 3 and the functional seat 15 corresponding to the light-emitting component 17 are unidirectional light-transmitting portions. When the light-emitting component 17 emits light, light can be transmitted through it. When the light-emitting component 17 does not emit light, it is not visible from the outside.

[0041] Of course, in practical applications, it is also feasible to make the parts of the stepping component 3 and the functional seat 15 corresponding to the light-emitting component 17 bidirectional light-transmitting parts, which also falls within the scope of protection of this technical solution.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Various modifications and variations can be made to the above embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
