Description

Technical Field

[0001] The utility model belongs to the technical field of balance bikes, and particularly relates to a balance bike. Background Art

[0002] A balance bike, also known as a body sense bike, a thinking bike, a positioning bike, etc. There are mainly two types on the market: unicycle and bicycle. Its operating principle is mainly based on a basic principle called "dynamic stability".

[0003] Some balance bikes on the market include an integrated vehicle body, on which two wheels are rotatably arranged, and pedals corresponding to the two wheels are arranged on the vehicle body. The relative movement of the two pedals is controlled respectively through the two pedals. For example, the steering-flexible balance bike disclosed in Chinese Utility Model Patent CN202122299054.0 includes a housing, a driving assembly, a pedal assembly and a detection assembly. The housing has a supporting surface for supporting the user's feet. The driving assembly is arranged in the housing for driving the housing to move; the pedal assembly includes a foot pedal which is swingably arranged on the supporting surface; the detection assembly is arranged in the housing for detecting the swing of the foot pedal and is electrically connected with the driving assembly. The technical solution of the utility model can improve the steering flexibility of the balance bike.

[0004] In the above structure, the swing of the foot pedal relative to the horizontal plane is directly detected by the detection assembly. Most of the detection assemblies of balance bikes on the market are gyroscopes. However, when the balance bike is going uphill, the vehicle body will tilt backward, and at this time, the foot pedal will also tilt backward with the vehicle body. In order to make the balance bike continue to go uphill, the foot pedal and the vehicle body need to rotate by a large amplitude, otherwise the speed of the balance bike will be slow or even it cannot climb the slope, but this is likely to cause the user to fall and accidents are likely to occur.

Detailed implementation manner

[0037] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments:

[0038] Refer to Figures 1 to 13 As shown, a self-balancing scooter includes a vehicle body 1 and two sets of wheels 2 rotatably arranged on the vehicle body 1. A driving device for controlling the movement of the wheels 2 and foot pedal assemblies 3 corresponding to the two sets of wheels 2 are provided on the vehicle body 1. A first gyroscope 5 is provided on the vehicle body 1. Rotating shafts 21 rotatably connected to the vehicle body 1 are provided on the wheels 2. The foot pedal assembly 3 includes a mounting seat 31 fixedly arranged on the rotating shaft 21. A second gyroscope 512 and a pedal 32 are provided on the mounting seat 31. The first gyroscope 5 and the second gyroscope 512 are electrically connected to the driving device; the driving device determines the relative inclination angle of the second gyroscope 512 based on the first gyroscope 5, and then determines the relative inclination angle of the mounting seat 31 and the vehicle body 1, so as to control the movement of the wheels 2 corresponding to the foot pedal assembly 3. In the above structure, the driving device determines the relative inclination angle of the mounting seat 31 and the vehicle body 1 through the first gyroscope 5 and the second gyroscope 512, and then controls the movement of the wheels 2, rather than only determining the relative inclination angle of the mounting seat 31 and the ground through the second gyroscope 512 to control the movement of the wheels 2.

[0039] During the use of the scooter, when the scooter climbs a slope, in a traditional scooter, only a gyroscope is provided on the pedal assembly 3. The front part of the pedal 32 needs to tilt downward to make the scooter continue to move forward. At this time, the pedal 32 needs to have a large inclination angle with the vehicle body 1. When the slope is large, it is very difficult for the user to control the pedal 32 and the vehicle body 1 to achieve such an inclination angle, resulting in the scooter being unable to climb the slope. Moreover, even if such an inclination angle is achieved, the user is prone to falling. However, in the present utility model, the first gyroscope 5 will tilt upward together with the front end of the vehicle body 1. The pedal 32 of the scooter needs to tilt slightly upward or downward, so that the detection structures of the first gyroscope 5 and the second gyroscope 512 have a large difference, so that the pedal assembly 3 can control the scooter to accelerate uphill by tilting slightly forward only, which can avoid the user falling due to the excessive tilt angle of the pedal 32 and is beneficial to improving the safety of the scooter.

[0040] When the scooter goes downhill, the front part of the pedal 32 of a traditional scooter needs to tilt slightly downward, or the front part of the pedal 32 of the scooter tilts upward. Only in this way can the downhill speed of the scooter be avoided from being too fast and the user being injured due to the too fast speed of the scooter. When the slope is large, it is very difficult for the user to control the pedal 32 and the vehicle body 1 to achieve such an inclination angle, resulting in the scooter going downhill too fast. Moreover, even if such an inclination angle is achieved, the user is prone to falling. However, in the present utility model, the first gyroscope 5 will tilt downward together with the front end of the vehicle body 1. The pedal 32 of the scooter needs to tilt slightly upward or downward, so that the scooter can decelerate or accelerate slightly, which can avoid the scooter from going too fast and is beneficial to improving the safety of the scooter.

[0041] In the present utility model, a plurality of limit blocks 14 are detachably arranged on the vehicle body 1. The limit blocks 14 are arranged below the mounting seat 31 and are respectively arranged on both sides of the rotating shaft 21. The mounting seat 31 can rotate relative to the vehicle body 1 to limit the rotation angle between the mounting seat 31 and the vehicle body 1. The arrangement of the limit blocks 14 can avoid the relative inclination angle between the mounting seat 31 and the vehicle body 1 from being too large, avoid the scooter from going too fast, and also avoid the user from falling due to the excessive tilt angle of the pedal 32. Moreover, since the limit blocks 14 are of a detachable structure, it is convenient for the production and assembly of the vehicle body 1, and it is convenient for the producer to change the height of the limit blocks 14 according to needs, so as to adjust the maximum rotation angle of the mounting seat 31, which is convenient for the flexible production and assembly of the scooter.

[0042] An induction device 511 for sensing heavy objects on the foot pedal assembly 3 is provided on the mounting base 31. A detection part 351 corresponding to the induction device 511 is provided on the foot pedal 32 or the mounting base 31. An elastic member 33 is provided between the foot pedal 32 and the mounting base 31 or the vehicle body 1. When a heavy object acts on the foot pedal 32, the foot pedal 32 moves relative to the mounting base 31, thereby changing the detection result of the induction device 511. The elastic member 33 is cylindrical, and the upper end of the elastic member 33 is connected to the outer periphery of the foot pedal 32. The lower end of the elastic member 33 extends to form an annular pressing edge 34. A pressing ring 6 is detachably provided on the vehicle body 1, and the pressing ring 6 presses the annular pressing edge 34 against the vehicle body 1. The cylindrical elastic member 33 and the annular pressing edge 34 are not only beneficial to the stable installation of the elastic member 33 and the foot pedal 32, but also can reduce the entry of sundries into the vehicle body 1, avoid damage to the balance bike caused by sundries, and is beneficial to extending the service life of the balance bike.

[0043] In this embodiment, the induction device 511 is an infrared induction switch, and the detection part 351 is in a sheet shape. The detection part 351 penetrates into the infrared induction switch and enables the infrared induction switch to sense the detection part 351.

[0044] The elastic member 33 and the foot pedal 32 of the present utility model are integrally provided. The integrally provided elastic member 33 and foot pedal 32 are convenient for the assembly and production of the balance bike, and can also prevent sundries from entering the vehicle body 1 through the gap between the elastic member 33 and the foot pedal 32, which is beneficial to extending the service life of the balance bike. In this embodiment, the elastic member 33 is made of rubber or elastic plastic, and the upper end of the elastic member 33 is glued or integrally injection-molded with the outer periphery of the foot pedal 32.

[0045] Preferably, the elastic member 33 includes a wavy deformation part 331. The wavy deformation part 331 is convenient for the stable contraction and extension of the elastic member 33, and avoids the deviation and dislocation of the foot pedal 32.

[0046] In the present utility model, the vehicle body 1 includes a detachable upper cover 12 and a lower cover 11. A foot pedal groove 121 is provided on the upper cover 12.

[0047] In this embodiment, an annular sealing convex edge 341 is provided on the annular pressing edge 34. The sealing convex edge 341 surrounds the bearing 23 of the foot pedal groove 121. A sealing groove 124 adapted to the sealing convex edge 341 is provided on the vehicle body 1 or the pressing ring 6. The pressing ring 6 drives the sealing convex edge 341 to press tightly in the sealing groove 124. The arrangement of the sealing convex edge 341 and the sealing groove 124 can not only improve the sealing performance between the elastic member 33 and the vehicle body 1, but also prevent the annular pressing edge 34 from detaching from between the pressing ring 6 and the vehicle body 1 due to the force on the elastic member 33, which is beneficial to the stable installation of the elastic member 33 and the vehicle body 1.

[0048] A detecting member 35 is detachably arranged on the mounting base 31. A detecting portion 351 is arranged on the detecting member 35. An elastic mounting flange 352 is arranged on the outer periphery of the detecting member 35. The detecting member 35 is mounted on the mounting base 31 through the mounting flange 352. The mounting flange 352 drives the detecting portion 351 to reset and move away from the sensing device 511. The pedal 32 can abut against the detecting member 35 to displace the detecting portion 351, thereby changing the detection result of the sensing device 511. The detachably arranged detecting member 35 facilitates the installation and maintenance of the detecting portion 351, and the arrangement of the elastic mounting flange 352 facilitates the automatic reset of the detecting portion 351, reduces the components of the scooter, and facilitates the assembly and production of the scooter.

[0049] In this embodiment, a control board 51 is arranged below the mounting base 31. A sensing device 511 and a second gyroscope 512 are arranged on the control board 51.

[0050] Two through holes 311 are arranged on the mounting base 31. The two through holes 311 are respectively arranged on the front and rear sides of the rotating shaft 21. A detecting member 35 is arranged in each through hole 311. Preferably, a mounting groove 316 is arranged above the through hole 311, a pressing groove 313 is arranged above the mounting groove 316. The outer periphery of the mounting flange 352 is arranged in the placement groove 312. A pressing ring 36 is detachably arranged in the pressing groove 313. A notch 361 for the detecting member 35 to pass through is arranged on the pressing ring 36. The detecting portion 351 can pass through the through hole 311 and enable the sensing device 511 to sense the detecting portion 351.

[0051] In this embodiment, at least three hook portions 362 are arranged on the circumference of the pressing ring 36. Hook grooves 314 adapted to the hook portions 362 are arranged at the bottom of the pressing groove 313. An inclined surface 363 is arranged on the hook portion 362.

A positioning protrusion 353 adapted to the positioning hole 315 is arranged at the lower end of the mounting flange 352. The clamping member is positioned and installed through the positioning hole 315 and the positioning protrusion 353, avoiding the misalignment between the detecting portion 351 and the sensing device 511 and affecting the normal use of the scooter. Preferably, a positioning flange 354 adapted to the through hole 311 is arranged on the lower side of the mounting flange 352. The arrangement of the positioning flange 354 can reduce the lateral deflection and misalignment of the detecting portion 351 during the movement process, facilitating the detection between the sensing device 511 and the detecting portion 351.

[0052] The wheel 2 is arranged at both ends of the vehicle body 1. A fender 7 is arranged between both ends of the vehicle body 1 and the wheel 2. Since many factories now use self-balancing scooters for transportation, the vehicle body 1 is easily knocked and damaged during use. Therefore, it is preferred that the outer side of the vehicle body 1 is wrapped with a hard shell 4, and an avoidance groove 411 corresponding to the footrest assembly 3 is arranged on the hard shell 4. The footrest assembly 3 passes through the avoidance groove 411 and is exposed outside. The wheel 2 and the hard shell 4 are respectively arranged at both ends and the outer side of the vehicle body 1, avoiding the vehicle body 1 being knocked and damaged during use, which is beneficial to extending the service life of the self-balancing scooter.

[0053] In this embodiment, the hard shell 4 includes an upper shell 41 and a lower shell 42 which are detachably arranged. The upper shell 41 and the lower shell 42 are combined to wrap the upper and lower sides as well as the front and rear sides of the vehicle body 1. Since the bottom of the self-balancing scooter is not easily touched by other objects, it is preferred that a hollow part is arranged on the lower shell 42. The hollow part can reduce the mass of the self-balancing scooter and lower the production cost.

[0054] A plurality of hinge seats 122 are arranged at intervals on the vehicle body 1. The rotating shaft 21 is rotatably connected to at least two hinge seats 122 through bearings 23.
