DETAILED DESCRIPTION

[0025] The preferred embodiments of the present application will be described in detail below with reference to the drawings. Those skilled in the art will appreciate that the description is merely illustrative, exemplary, and should not be construed as limiting the scope of the present application.

[0026] It should be noted that similar reference numerals refer to similar items throughout the drawings and that, once an item is defined in one drawing, it can not be further defined and explained in subsequent drawings.

[0027] Figures 1-6 As shown, the height-adjustable exercise bike comprises a frame 1, a handle 11, a seat cushion 9, a pedal mechanism 7 and a controller 6.

[0028] At least one side of the frame 1 is provided with a lifting mechanism 3, which is mounted at the bottom of the frame 1 as a support part. The lifting mechanism 3 comprises a motor 16, a lifting rod 17 coupled with the motor 16 and movable up and down relative to the frame 1. The lower end of the lifting rod 17 is provided with a base 14, and the lifting rod 17 is rotatable relative to the base 14. The motor 16 is electrically connected with the controller 6, and the working state of the motor 16 is controlled by the controller 6, so as to control the lifting rod 17 to move up or down relative to the frame 1. The height of one side of the frame 1 is changed when the lifting rod 17 moves up and down relative to the frame 1.

[0029] For example, when the lifting mechanism 3 is arranged at the front side of the frame 1, the front side of the frame 1 can be lifted by moving the lifting rod 17 up and down relative to the frame 1, and the frame 1 is inclined backward to simulate the effect of "uphill". When the lifting mechanism 3 is arranged at the rear side of the frame 1, the rear side of the frame 1 can be lifted by moving the lifting rod 17 up and down relative to the frame 1, and the frame 1 is inclined forward to simulate the effect of "downhill". When the lifting mechanism 3 is arranged at the left side or the right side of the frame 1, the left side or the right side of the frame 1 can be lifted by moving the lifting rod 17 up and down relative to the frame 1, and the frame 1 is inclined to the right or to the left to simulate the effect of "bend" riding.

[0030] The lifting rod 17 is rotatable relative to the base 14. When the lifting rod 17 moves up and down relative to the frame 1, the frame 1 is inclined, and the base 14 is always in a flat state in contact with the ground through the rotation of the lifting rod 17 and the base 14.

[0031] Figure 1 、 Figure 2 As shown, preferably, the bottom of the frame 1 is provided with four lifting mechanisms 3, which are respectively located at the left and right sides of the front side of the frame 1 and the left and right sides of the rear side of the frame 1. The four lifting mechanisms 3 support the four corners of the frame 1, so as to control the height of the four corners of the frame 1 respectively.

[0032] For example, the lifting rods 17 of the lifting mechanisms 3 on the left and right sides of the front side of the frame 1 are lowered relative to the frame 1, so that the lifting mechanisms 3 on the left and right sides of the front side of the frame 1 are raised, and the frame 1 is inclined backward to simulate the effect of "uphill"; the lifting rods 17 of the lifting mechanisms 3 on the left and right sides of the rear side of the frame 1 are lowered relative to the frame 1, so that the lifting mechanisms 3 on the left and right sides of the rear side of the frame 1 are raised, and the frame 1 is inclined forward to simulate the effect of "downhill"; the lifting rods 17 of the lifting mechanisms 3 on the front and back of the left side or the right side of the frame 1 are lowered relative to the frame 1, so that the lifting mechanisms 3 on the front and back of the left side or the right side of the frame 1 are raised, and the frame 1 is inclined to the right or to the left to simulate the effect of "bend" riding; the lifting rods 17 of the four lifting mechanisms 3 can also be raised or lowered simultaneously to control the overall lifting of the frame 1.

[0033] The frame 1 includes a front chassis 2, a rear chassis 13, and a vertical frame 12. The front chassis 2 and the rear chassis 13 are horizontally arranged, and the front and rear sides of the vertical frame 12 are fixedly connected to the middle parts of the front chassis 2 and the rear chassis 13, respectively. Two of the four lifting mechanisms 3 are installed at the bottom of the two ends of the front chassis 2, and the other two of the four lifting mechanisms 3 are installed at the bottom of the two ends of the rear chassis 13.

[0034] The front chassis 2 and the rear chassis 13 are horizontally arranged to the left and right sides to install the lifting mechanisms 3, so that the front chassis 2 and the rear chassis 13 can better support the frame 1, and the frame 1 is less likely to fall over when it is inclined to one side. The height of the frame 1 raised by the lifting mechanisms 3 is slightly lower, so that the angle of inclination is not too large, and the frame 1 is less likely to be overturned due to inclination.

[0035] Figures 3-6 As shown, the lifting mechanism 3 includes a housing 15 fixed to the frame 1, and the lifting rod 17 is accommodated in the housing 15. The lower end of the lifting rod 17 extends out of the housing 15 and is supported on the lower base 14. A transmission assembly is provided between the lifting rod 17 and the motor 16 to transmit the power output by the motor 16 to the lifting rod 17, so that the lifting rod 17 moves up and down relative to the housing 15. The motor 16 is fixed to one side of the housing 15.

[0036] For example, when the controller 6 controls the motor 16 to rotate forward, the transmission assembly transmits the power output by the motor 16 to the lifting rod 17, so that the lifting rod 17 extends downward out of the housing 15, thereby raising the frame 1. When the controller 6 controls the motor 16 to rotate backward, the transmission assembly transmits the power output by the motor 16 to the lifting rod 17, so that the lifting rod 17 retracts upward into the housing 15, thereby lowering the raised frame 1.

[0037] Preferably, the lifting mechanism 3 is a worm gear lifting mechanism, which is a conventional lifting structure, such as the SWLD electric worm gear lifting mechanism available in the market, wherein the motor 16 is a stepping motor 16. In detail, the transmission assembly comprises a worm connected with the motor shaft of the motor 16 and a worm gear arranged in the housing 15 and engaged with the worm. The lifting rod 17 is a screw rod, the center of the worm gear is provided with a threaded hole threadedly connected with the screw rod, the circumferential surface of the screw rod is provided with a limiting rotation groove extending along the length direction of the screw rod, the housing 15 is provided with a limiting rotation block engaged with the limiting rotation groove, and the motor shaft drives the worm to rotate when the motor 16 is started, the worm drives the worm gear to rotate, and the screw rod is driven to move up and down by the screw thread of the internal threaded hole of the worm gear due to the relative rotation restriction between the screw rod and the housing 15.

[0038] Figure 6 As shown, preferably, the lower end of the lifting rod 17 is fixed with a ball head 18, the top surface of the base 14 is provided with an inner recessed assembly groove 19, and the ball head 18 is limited to rotate in the assembly groove 19. Through the cooperation of the ball head 18 and the assembly groove 19, the lifting rod 17 can rotate at multiple angles relative to the base 14 through the ball head 18, so that the four lifting mechanisms 3 are more smooth in the process of lifting the frame 1 to incline the frame 1 to any side of front, back, left and right, and are not easy to be stuck, and no matter which side of the lifting mechanism 3 controls the lifting, the four bases 14 at the bottom are always in a flat state.

[0039] The assembly groove 19 is a spherical groove, the top surface of the base 14 is provided with an opening for the ball head 18 to be assembled into the assembly groove 19, and the diameter of the opening is smaller than the diameter of the ball head 18. The ball head 18 can be assembled into the assembly groove 19 through elastic deformation after extrusion.

[0040] In addition, the base 14 is in the shape of a circular truncated cone, and the outer diameter of the base 14 gradually increases from top to bottom, so that the base 14 placed on the ground can provide more stable support.

[0041] The bottom surface of the base 14 is provided with anti-skid lines, which can provide better anti-skid effect during use.
