Embodiment I

[0032] As shown in FIG. 3 to FIG. 6, a flexible trainer stand for indoor cycling includes a bracket 1, a flat plate 2, a first guide portion 3, a second guide portion 4, and elastic devices 5. The first guide portion 3 is arranged at a top end of the bracket 1. The second guide portion 4 is arranged at a bottom end of the flat plate 2. The first guide portion 3 is slidably connected with the second guide portion 4. A beam 11 is fixedly arranged at one end of the bracket 1. The elastic devices 5 are symmetrically arranged at two ends of the beam 11. Each of the elastic devices 5 includes one end fixedly connected with the beam 11, and the other end fixedly connected with the bottom end of the flat plate 2.

[0033] In the present disclosure, the first guide portion 3, the second guide portion 4, and the elastic device 5 are arranged, and the first guide portion 3 and the second guide portion 4 can slide relative to each other, which can simulate forward and backward movement of a bike generated when a user accelerates and sprints. The first guide portion 3 and the second guide portion 4 can be inclined, and under an action of the elastic device 5, left and right inclination of the bike generated when the user is cycling can be simulated. Therefore, the above arrangement can enable the user to truly simulate somatosensory feedback during outdoor cycling, and a feedback force can be adjusted, so as to improve an indoor cycling effect.

[0034] On the basis of the above technical solution, a contact point of the first guide portion 3 and the second guide portion 4 has a cross section arranged in available forms such as an arc shape, a V shape, or a reuleaux triangle shape. The first guide portion 3 and the second guide portion 4 can slide relative to each other, which can simulate forward and backward movement of a bike generated when the user accelerates and sprints. In addition, angle inclination can also be achieved, such that left and right inclination of the bike generated when the user is cycling can be simulated.

[0035] On the basis of the above technical solution, the first guide portion 3 is arranged as a roller, and the second guide portion 4 is arranged as a guide rail, or the first guide portion 3 is arranged as a guide rail, and the second guide portion 4 is arranged as a roller. Installation positions of the first guide portion 3 and the second guide portion 4 can be interchanged, which can meet the needs of use in a high-load use environment.

[0036] On the basis of the above technical solution, as shown in FIG. 6, each of the elastic devices 5 is arranged as a hollow rubber tube 51. Two ends of the hollow rubber tube 51 are each provided with a metal joint 52. A free end of the metal joint 52 is fixedly connected with the bottom end of the flat plate 2 and the beam 11 separately. Preferably, a passive energy storage device such as a spring, an elastic ball, and a gas spring can be selected as the elastic device 5. The above flexible support design reduces a stress on a cycling training frame, prolongs a service life, and reduces training costs. In addition, the number and specification of the elastic device 5 can be replaced, and the elastic device 5 can be selected according to the needs of the user such as an actual weight, which can effectively improve comfort of the user during cycling training.

[0037] On the basis of the above technical solution, a plurality of rollers are arranged. The number of the roller can be selected according to the weight of the user and the total weight of equipment carried on the flat plate. In addition, different arrangement forms of the plurality of rollers can be set according to different needs of the user. The feedback force can be adjusted while achieving real somatosensory simulation, so as to improve an indoor cycling effect.

[0038] On the basis of the above technical solution, the guide rail has a segmented structure, and any two adjacent sections of the guide rail are detachably connected. By setting the guide rail as segmented, it can be applied to rocker plates of different sizes and has a wide range of application.

[0039] During indoor simulation training, when the user exerts a force or accelerates, the left and right inclination of the bike will drive a contact position of the first guide portion 3 and the second guide portion 4 to be inclined with a certain angle. At this time, the elastic device 5 on one side is stretched in a deflection direction of the bike, and the elastic device 5 on the other side is unstressed to complete an energy storage process. When the trend of left and right inclination disappears, the elastic device 5 releases energy stored, and both sides of the flexible trainer stand will return to a horizontal state.

[0040] When the user changes the posture to sprint and accelerate, the center of gravity of the body tends to lean forward, and the bike drives the first guide portion 3 and the second guide portion 4 to slide relative to each other. At this time, the elastic devices 5 at two ends of the beam 11 are stretched in a sliding direction to complete the energy storage process. When the trend of forward leaning of the center of gravity disappears, the energy stored is released, and the flexible trainer stand will return to its original position.

Embodiment II

[0041] The difference from Embodiment I is that the first guide portion 3 may be arranged as a guide rail, the second guide portion 4 may be arranged as a guide post, the guide post is slidably connected with the guide rail, and angle inclination can also be achieved. Likewise, installation positions of the first guide portion 3 and the second guide portion 4 can also be interchanged. More preferably, the guide post is rotatably connected with the top end of the bracket 1 or the top end of the flat plate 2, such that the bike can be inclined more flexibly during simulation of cycling force exertion.

Embodiment III

[0042] On the basis of the above embodiments, as shown in FIG. 7 and FIG. 8, the present disclosure further includes a lifting device 6 fixed on the flat plate 2. The lifting device 6 includes a roller 61, a bottom plate 62, a power mechanism 63, a conveyor belt 64, a driving wheel 65, and a driven wheel 66. The roller 61 is arranged at a bottom end of the bottom plate 62. The power mechanism 63 is fixedly arranged at a top end of the bottom plate 62. The driving wheel 65 is arranged coaxially with the power mechanism 63. The driving wheel 65 drives the driven wheel 66 to rotate through the conveyor belt 64. A connecting member 7 is fixedly arranged on the conveyor belt 64.

[0043] On the basis of the above technical solution, the power mechanism 63 includes a driving motor 631, a worm 632, and a worm gear 633. The worm 632 is arranged on the driving motor 631 through a coupler 634. The worm gear 633 is meshed with the worm 632. The worm gear 633 is arranged coaxially with and rotates synchronously with the driving wheel 65.

[0044] The lifting device 6 is arranged on the flat plate 2, such that the user can simulate position changes of the bike in a vertical direction when a slope changes, and a simulated feedback effect is real, which improves the indoor training effect and experience of indoor cycling. During specific use, a front frame of the bike is fixedly installed on the connecting member 7. The power mechanism 63 is started to drive the driving wheel 65 to rotate. The driving wheel 65 drives the driven wheel 66 to rotate through the conveyor belt 64. The connecting member 7 is driven by the conveyor belt to realize up and down movement, so as to drive the front frame of the bike to realize the position changes in the vertical direction, and truly simulate the slope changes during outdoor cycling.

[0045] On the basis of the above technical solution, as shown in FIG. 8, the lifting device 6 is externally provided with a shell 67. A sliding chute 68 is symmetrically formed in a side wall of the shell 67. The connecting member 7 is slidably connected in the sliding chute 68. The lifting device 6 is provided with the shell 67 on the outer side, such that the normal operation of the lifting device 6 can be protected, and potential safety hazards caused by user contact can be avoided. The sliding chute 68 is formed in the side wall of the shell 67 to guide the connecting member 7, so as to prevent the front frame of the bike from shaking and swinging in an up and down lifting process, which affects the user experience.

[0046] When the user needs to experience the slope change simulation, the lifting device 6 will receive a power change signal sent by the cycling training equipment such as a bike trainer fixed on the flat plate 2 through a Bluetooth device, and then convert it into slope data. Then the slope data is used in the control of operation of the driving motor 631, and then the conveyor belt 64 is driven to run. The connecting member 7 fixed on the conveyor belt 64 drives the front frame of the bike to change in position in the vertical direction, such that the user can experience the somatosensory feedback brought by the real slope changes.

[0047] The present disclosure provides the flexible trainer stand for indoor cycling, which can effectively provide feedback on the road feeling and somatosensory feeling during cycling in real environment. In the training process, the habit of exerting a force and the cycling posture can be adjusted according to the changes of the feedback of the flexible trainer stand to improve the indoor training effect. In addition, the feedback force can be adjusted to adapt to more user groups. Moreover, the present disclosure also has the advantages of simple structure, ultra-silence, and light weight, is convenient to use and carry, can support all commercially available cycling training equipment such as bike trainers and spinning bikes, and has a wide range of application.
