Description

Technical Field

[0001] The present application relates to the field of fitness equipment, and in particular to a spinning bike. Background Art

[0002] Spinning bike is a common cycling fitness equipment, which is deeply loved by users. Existing spinning bikes will combine the application of VR technology to simulate complex road conditions and different scenes in visual effects, giving users an immersive feeling, but the simulation is only visual, the user's physical experience is weak, and the experience effect is limited. Summary of the invention

[0003] In order to solve the problem of weak user physical experience when riding, the present application provides a spinning bike.

[0004] The present application provides a spinning bike that adopts the following technical solution:

[0005] A dynamic bicycle can simulate riding on different road conditions, comprising: a body, the body comprising a frame, wheels mounted on the frame, a buffer device connected between the frame and the wheels; a base, the base comprising a support seat, a smooth roller for supporting the wheels is rotatably connected to the support seat, a driving member is also fixedly provided on the support seat, a lifting block is fixedly connected to the output end of the driving member and can drive the lifting block to move, a lifting roller capable of supporting the wheels is rotatably connected to the lifting block, a convex block is fixedly connected to the outer peripheral surface of the lifting roller, and the smooth roller is arranged parallel to the axis of the lifting roller.

[0006] By adopting the above technical solution, when the lifting roller is not in contact with the wheel, the wheel is supported only by the smooth roller, and the smooth roller is used to simulate a flat road condition; and the lifting block and the lifting roller are driven to rise by the driving member until the lifting roller also comes into contact with the wheel. At this time, the lifting roller and the smooth roller jointly support the wheel, and when the user rides, the rolling of the wheel will drive the lifting roller to rotate. During the rotation of the lifting roller, the convex block will contact the wheel, causing the wheel to vibrate up and down. Combined with the buffer device's buffering and shock absorption of the frame, riding on bumpy roads can be simulated, thereby giving users a better physical experience.

[0007] Further preferably, the buffer device includes a connecting rod and an elastic member, one end of the connecting rod is hinged to the axle of the wheel, and the other end is slidably connected to the frame, the direction in which the connecting rod slides relative to the frame is perpendicular to the axis of the wheel, and the elastic member is fixedly connected between the connecting rod and the frame.

[0008] By adopting the above technical solution, the sliding direction of the connecting rod relative to the frame is perpendicular to the axis of the wheel, thereby avoiding the connecting rod and the frame from getting stuck during buffering and shock absorption.

[0009] Further preferably, two wheels are provided, buffer devices are connected between the two wheels and the frame, and the connecting rods in the two buffer devices are parallel to the sliding direction of the frame.

[0010] By adopting the above technical solution, when there are two wheels, buffer devices are connected between the wheels and the frame, and the connecting rods in the two buffer devices are parallel to the sliding direction of the frame to avoid the connecting rods and the frame from getting stuck.

[0011] Further preferably, the base also includes a support seat 2, and a locking mechanism is connected between the support seat 2 and the frame, and the frame and the support seat 2 are detachably fixedly connected through the locking mechanism. The locking mechanism includes a card block slidably connected to the support seat 2, and a driving member 2 that drives the card block to slide. The driving member 2 is fixedly connected to the support seat 2, and a bayonet for clamping the card block is opened on the frame.

[0012] By adopting the above technical solution, the support seat two and the frame are detachably fixed by a locking mechanism, which is convenient for disassembly and maintenance of the vehicle body. When the locking mechanism does not fix the frame and the support seat two, it can be used to experience riding on bumpy roads. When the locking block is driven by the driving member two to insert into the bayonet, and the frame and the support seat two are fixed by the locking mechanism, the frame will not be bumpy, which is suitable for children to ride and has high safety.

[0013] Further preferably, a groove is provided on the support seat 2, the bottom of the frame is inserted into the groove, and the clamping block is slidably arranged in the groove along a direction perpendicular to the insertion direction of the frame.

[0014] By adopting the above technical solution, the frame and the second support seat are also plugged in through the groove to enhance the connection effect. The bottom of the frame is first inserted into the groove, and the card block is arranged in the groove and engaged with the bayonet. The sliding direction of the card block is along the plug-in direction perpendicular to the frame. After the card block is engaged with the bayonet, it can prevent the frame from being separated from the second support seat.

[0015] Further preferably, the vehicle body also includes a foot pedal, which is rotatably connected to the frame, and the foot pedal is connected to the wheel via a chain, and when the foot pedal is rotated to a vertically downward position, the bottom of the frame is lower than the foot pedal.

[0016] By adopting the above technical solution, when the foot pedal is rotated to a vertically downward position, the bottom of the frame is still lower than the foot pedal, thereby avoiding interference between the foot pedal and the support seat 2 during the rotation process, and also avoiding the foot pedal affecting the connection between the frame and the support seat 2.

[0017] Further preferably, the spinning bike also includes a tilting device, which includes an arc guide rail fixedly connected to the support seat one and a driving mechanism, the support seat two is slidably connected to the arc guide rail and driven by the driving mechanism, and the driving mechanism drives the support seat two to swing in a vertical plane.

[0018] By adopting the above technical solution, the support seat 2 is driven by the driving mechanism to slide along the arc-shaped guide rail, thereby driving the vehicle body to slide along the arc-shaped guide rail, so that the vehicle body is tilted to simulate turning riding.

[0019] Further preferably, the arc angle of the arc guide rail is between 15° and 25°.

[0020] By adopting the above technical solution, the arc angle is set between 15° and 25° to simulate the degree of inclination during actual riding. In addition, when tilted, the load borne by the block in the locking mechanism increases, and the inclination angle is avoided to be too large, thereby extending the service life of the locking mechanism.

[0021] Further preferably, the driving mechanism includes a transmission belt, a pulley and a driving member three for driving the pulley to rotate, and the driving member three is fixed on the arc guide rail.

[0022] By adopting the above technical solution, a belt outlet groove is opened on the arc guide rail to guide the transmission belt, thereby preventing the transmission belt from falling off during the transmission process and improving the transmission reliability.

[0023] Further preferably, the spinning bike further comprises a protection device, which comprises a stand fixed on the base, the stand being provided with a ring hole for a person to pass through, and a protective pad being fixed in the ring hole.

[0024] By adopting the above technical solution, a protective device is provided to improve the safety during riding and prevent the user from falling from the vehicle body.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. In this application, riding on smooth roads, bumpy roads and curved roads can be simulated, and the user's physical experience can be given to enhance the physical effect;

[0027] 2. In the further configuration of the present application, a locking mechanism is provided between the frame and the second support seat to facilitate disassembly, installation and maintenance, and the connection is enhanced in two ways: the card block is connected with the card port and the bottom of the frame is connected with the groove, so as to enhance the connection strength and improve the safety;

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1 -Attached Fig.10 This application is described in further detail.

[0041] The present application discloses a spinning bike that can simulate riding under different road conditions and is used for fitness training and sports training. The present application provides the following embodiments:

[0042] Embodiment 1

[0043] As attached Figure 1 To Attachment Figure 4As shown, the spinning bike comprises a body 1 and a base 2 for supporting the body 1, the body 1 comprises a frame 11, two wheels 12 and a pedal 15, the pedal 15 is rotatably connected to the frame 11 and connected to the two wheels 12 through parts such as a flywheel and a chain, and a user can drive the two wheels 12 to rotate synchronously counterclockwise by stepping on the pedal 15, and a buffer device is connected between the frame 11 and the wheels 12 to achieve a buffering and shock absorbing effect;

[0044] The base 2 includes a support seat 22, on which a smooth roller 221 for supporting the wheel 12 is rotatably connected, and a driving member 224 is fixedly provided on the support seat 22. A lifting block 225 is fixedly connected to the output end of the driving member 224 and can drive the lifting block 225 to move. A lifting roller 222 capable of supporting the wheel 12 is rotatably connected to the lifting block 225, and a protrusion 223 is fixedly connected to the outer peripheral surface of the lifting roller 222. The smooth roller 221 is arranged parallel to the axis of the lifting roller 222.

[0045] In this embodiment, two support seats 1 22 are provided. To enhance stability, an additional counterweight (not shown) is provided on the support seat 1 22 to increase the weight of the support seat 1 22. Two smooth rollers 221 are rotatably connected to each support seat 1 22. The smooth rollers 221 are arranged in parallel and their axes are along the front-to-back direction. The axis spacing between the two smooth rollers 221 on the same support seat 1 22 is smaller than the diameter of the wheel 12; a lifting roller 222 is provided on each support seat 1 22, and the lifting roller 222 is located between the two smooth rollers 221 on the same support seat 1 22.

[0046] Specifically, for the convenience of explanation, the wheel 12 on the left is called the front wheel, and the wheel 12 on the right is called the rear wheel. The diameters of the front wheel and the rear wheel are the same, and the axes of the two wheels 12 are also in the front-to-back direction. Two support seats 12 are arranged in a left-right distribution, and the two smooth rollers 221 on the left support seat 12 support the front wheel, and the two smooth rollers 221 on the right support seat 12 support the rear wheel. The axis spacing of the two smooth rollers 221 on the same support seat 12 is the same as the radius of the wheel 12, and the sum of the diameter of the smooth roller 221 and the diameter of the lifting roller 222 is smaller than the radius of the wheel 12, so that the lifting roller 222 avoids collision with the smooth roller 221 during the lifting process.

[0047] Two driving members 224 and two lifting blocks 225 are fixedly arranged on each supporting seat 22. The two driving members 224 are arranged front to back in a distributed manner, and the two lifting blocks 225 are also arranged front to back in a distributed manner. The front lifting block 225 is fixed to the output end of the front driving member 224, and the rear lifting block 225 is fixed to the output end of the rear driving member 224. The front and rear ends of the rotating shaft of the lifting drum 222 are rotatably connected to the two lifting blocks 225 respectively. The rotating shaft of the lifting drum 222 extends front to back and is rotatably connected to the front and rear lifting blocks 225.

[0048] Initially, the lifting roller 222 is located at the lower limit position. At this time, the wheel 12 is supported only by two smooth rollers 221. When the user is riding, the wheel 12 can drive the smooth roller 221 to rotate, simulating riding on a flat road. When it is necessary to simulate riding on a bumpy road, the lifting block 225 is driven by the driving member 224 to rise, thereby driving the lifting roller 222 to rise and abut against the wheel 12. At this time, the rotation of the wheel 12 can drive the lifting roller 222 to rotate as well, and the bump 223 set on the lifting roller 222 can cause the wheel 12 to vibrate up and down, thereby simulating a bumpy road section. In addition, the buffer device between the frame 11 and the wheel 12 can simulate a shock absorbing effect, further improving the user experience.

[0049] The driving member 1 224 can be driven by a cylinder, a hydraulic cylinder or a screw rod to drive the lifting block 225 to move up and down. In this embodiment, the driving member 1 224 is driven by a hydraulic cylinder, and the lifting is stable. In addition, during the process of riding on simulated bumpy roads, the wheel 12 will generate a downward pushing force on the lifting roller 222. The hydraulic cylinder drive can provide sufficient supporting force when the lifting roller 222 abuts against the wheel 12, thereby reducing the extent to which the lifting roller 222 is pushed downward by the wheel 12.

[0050] The supporting force provided by the cylinder drive is smaller than the supporting force provided by the hydraulic cylinder drive. Therefore, the cylinder-driven lifting roller 222 moves downward relatively more under the pushing force of the wheel 12, and the simulated riding experience is poor, while the economic cost of the cylinder drive is low. The screw drive can also provide sufficient supporting force for the lifting roller 222, but the downward pushing force of the wheel 12 on the lifting roller 222 is mainly borne by the thread of the screw, which will result in a short service life of the screw and frequent maintenance and replacement.

[0051] The driving member 224 can be controlled to start and stop and switch forward and reverse drive by remote control, and the control switch (not shown) can be set on the vehicle body 1, such as on the handlebar, so that the user can switch it on and off by himself.

[0052] The buffer device includes a connecting rod 13 and an elastic member 14. One end of the connecting rod 13 is hinged to the axle of the wheel 12, and the other end is slidably connected to the frame 11. The sliding direction of the connecting rod 13 relative to the frame 11 is perpendicular to the axis of the wheel 12, and the elastic member 14 is fixedly connected between the connecting rod 13 and the frame 11. In this embodiment, buffer devices are connected between the two wheels 12 and the frame 11, and the sliding directions of the connecting rods 13 in the two buffer devices relative to the frame 11 are parallel.

[0053] Specifically, the axle of the wheel 12 is along the front-to-back direction, and the connecting rods 13 in the two groups of buffer devices can slide relative to the frame 11 in the up-down direction, so that the user can experience the bumpy feeling of up-and-down vibration when riding on simulated bumpy roads.

[0054] In this embodiment, a spring is used for better elasticity, which is convenient for installation and replacement. In other embodiments, the buffer device can also use pneumatic buffering.

[0055] In addition, the spinning bike is also provided with a protective device 3, which includes a stand 31 fixed on the base 2, a ring hole 32 for a person to pass through is provided on the stand 31, and a protective pad 33 is fixed in the ring hole 32. In this embodiment, the ring hole 32 is arranged just above the seat cushion of the vehicle body, and the person passes through the ring hole 32 from above the ring hole 32 and sits on the seat cushion. During riding, the swinging of the limbs of the human body varies in size, and the waist of the human body hardly swings significantly. In this embodiment, the protective pad 33 fits the waist of the human body, thereby reducing the relative friction between the human body and the protective pad 33. The protective pad 33 adopts an elastic member 14, so that the protective pad 33 can better fit the human body. When riding on simulated bumpy roads, if the handlebars are lost, the protective pad 33 can also prevent the person from falling directly from the vehicle body 1, thereby improving the safety of use.

[0056] Embodiment 2

[0057] As attached Figure 5 , Attachment Figure 6 As shown, the base 2 in this embodiment also includes a second support seat 21, and a locking mechanism is connected between the second support seat 21 and the frame 11. The frame 11 and the second support seat 21 are detachably fixedly connected by the locking mechanism. After the locking mechanism fixes the second support seat 21 to the frame 11, the frame 11 will not vibrate, further enhancing riding safety. The second support seat 21 and the first support seat 22 can be integrally formed to improve stability, and the weight can also be increased by adding a counterweight (not shown) to improve stability.

[0058] The locking mechanism includes a block 211 slidably connected to the support seat 21, a driving member 212 driving the block 211 to slide, the driving member 212 is fixedly connected to the support seat 21, and a bayonet 213 for engaging the block 211 is provided on the frame 11. In addition, a groove 214 can be provided on the support seat 21, the block 211 is arranged in the groove 214, the bottom of the frame 11 is plugged into the groove 214, and the block slides in the groove along a direction perpendicular to the frame plugging. In this embodiment, when connecting the frame 11 and the support seat 21, the bottom of the frame 11 is first plugged into the groove 214 to facilitate the alignment and installation of the block 211 and the bayonet 213, and then the block 211 is driven by the driving member 212 to be plugged into the bayonet 213 for connection. In other embodiments, the locking mechanism can also be detachably connected by fasteners such as bolts. The locking mechanism in this embodiment is more convenient for disassembly, replacement and maintenance than bolts.

[0059] Specifically, the side wall of the groove 214 and the bottom of the frame 11 can be processed with mesh patterns to increase friction, and the block 211 and the bayonet 213 can be made into an interference fit connection to ensure the connection strength. The block 211 and the bayonet 213 are connected by driving the second driving member 212.

[0060] In this embodiment, the second driving member 212 can be driven by one of the following: a cylinder, a hydraulic cylinder, and a screw. Similarly, the second driving member 212 can also be controlled by a remote control, and its control switch is installed on the handlebar.

[0061] When the pedal 15 is rotated to a vertically downward position, the bottom of the frame 11 is lower than the pedal 15, which is convenient for plugging the frame 11 with the second support seat 21, and also prevents the pedal 15 from rotating and interfering with the second support seat 21 during riding.

[0062] Embodiment 3

[0063] As attached Figure 7 To Attachment Fig. 9 As shown, in this embodiment, the spinning bike further includes a tilting device 4, which includes an arc-shaped guide rail 41 and a driving mechanism 42. The support seat 21 is slidably connected to the arc-shaped guide rail 41 and driven by the driving mechanism 42. The driving mechanism 42 drives the support seat 21 to slide along the arc-shaped guide rail 41 and swing in a vertical plane. After the frame 11 is fixedly connected to the support seat 21, the tilting device 4 is used to swing the support seat 21, thereby driving the frame 11 and the user to tilt, and experience riding on a curve. The wheel 12 is kept in contact with the smooth roller 221 under the action of the buffer device, and the user is prevented from falling off the vehicle body 1 under the action of the protective device 3.

[0064] In this embodiment, the second support seat 21 and the first support seat 22 are separately provided, and the arc guide rail 41 and the first support seat 22 can be fixedly connected to enhance stability.

[0065] The arc angle of the arc guide rail 41 is between 15° and 25°, which can prevent the user from being pressed on the stand 31 due to a large inclination angle, thereby reducing the user experience. It can also prevent the locking mechanism from being damaged by excessive load.

[0066] The driving mechanism 42 includes a transmission belt 421, a pulley 422, and a driving member 3 423 for driving the pulley 422 to rotate. The driving member 3 423 is fixed on the arc-shaped guide rail 41. In this embodiment, the pulleys 422 are distributed along the length direction of the arc-shaped guide rail 41, and their distribution tracks are adapted to the arc of the arc-shaped guide rail 41. The support seat 21 is fixed to the upper end of the transmission belt 421. Under the driving action of the driving member 3 423, the transmission belt 421 runs, and drives the support seat 21 to slide along the arc-shaped guide rail 41.

[0067] In this embodiment, the driving member 423 is driven by a motor, and a switch for remotely controlling the start and stop and forward and reverse rotation of the motor is arranged on the handlebar.

[0068] Embodiment 4

[0069] As attached Fig.10 As shown, the difference from the third embodiment is that in this embodiment, only one wheel 12 is provided, and only one corresponding support seat 22 is provided.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
