For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The utility model provides a fitness bench, such as Figure 1a-Figure 4 As shown, the fitness stool includes a stool body 11, a seat cushion 12, a backrest 13, a plurality of pulleys 3, a pull rope 4 and a motor 51.

[0052] The stool body 11 constitutes the main structure of the fitness stool. The seat cushion 12 covers a portion of the upper surface of the stool body 11 in the length direction, and the backrest 13 can cover another portion of the upper surface of the stool body 11 in the length direction. The backrest 13 and the seat cushion 12 are connected to form the seat surface of the stool body 11 together.

[0053] The backrest 13 includes a first end 131 close to the seat cushion 12 and a second end 132 located on the opposite side of the first end 131. The first end 131 is rotatably connected to the stool body 11, and the second end 132 can be turned upward relative to the stool body 11 or covered downward on the upper surface of the stool body 11. The backrest 13 includes a leaning surface 133 facing the outside of the stool body 11 and a functional surface 134 located on the back of the leaning surface 133. The backrest 13 can provide support for the user during the training process of the fitness bench, allowing the user to obtain support when performing different fitness movements, and increasing the flexibility of use.

[0054] The wheel surfaces of the plurality of pulleys 3 are located on the same plane. The plurality of pulleys 3 include at least two first pulleys 31 and at least one second pulley 32. The second end 132 of the first pulley 31 close to the backrest 13 is arranged on the functional surface 134. The second pulley 32 can be slidably arranged relative to the functional surface 134 of the backrest 13. The number of the first pulley and the second pulley can be determined as required. For example, Figure 3a-Figure 5 In the embodiment shown, three first pulleys are provided and two second pulleys are provided, which can achieve a longer stretching length and increase the stretching distance of the user. In other embodiments, two first pulleys are provided and only one second pulley is provided, which can also achieve the force transmission function of the present application.

[0055] The pull rope 4 is alternately wound around the circumference of the first pulley 31 and the circumference of the second pulley 32. That is to say, taking the smooth winding from left to right as an example, the pull rope 4 is wound around the first first pulley 31 on the left side of the backrest 13, and then is wound around the first second pulley 32 on the left side downwardly, and then returns upward to the top of the backrest 13 to be wound around the second first pulley 31 on the left side, and then is wound around the second second pulley 32 on the left side downwardly again, and in this way, it is wound around all the first pulleys 31 and the second pulleys 32 in turn to connect the first pulleys 31 and the second pulleys 32.

[0056] The output end of the motor 51 is connected to the second pulley 32 and provides a resistance in the opposite direction to the force of the pull rope 4 to the second pulley 32. By adjusting the output force and / or output form of the motor 51, the corresponding resistance can be provided for the fitness bench according to the needs of the user. The motor 51 is a variable speed motor, specifically, the motor 51 can be a torque motor, and its torque is adjustable.

[0057] The two ends of the pull rope 4 are the action ends 41 for the user to apply external force. The user can transfer the force to the second pulley 32 by pulling the action end 41. At the same time, the second pulley 32 transfers the resistance output by the motor 51 to the user through the pull rope 4 to perform strength training.

[0058] The fitness bench provided by the above solution uses a motor to provide resistance for user training, and can adjust the size and form of resistance according to user needs, so that the fitness bench can support a variety of exercise methods rather than being limited to single resistance training, thereby increasing the diversity of user exercise, improving the personalization and flexibility of the fitness bench, and allowing the fitness bench to meet the needs of all types of people, from beginners to advanced users with specific exercise needs, thereby improving user experience.

[0059] In some embodiments, a force transmission seat 2 that is slidably matched with the functional surface 134 is also provided on the functional surface 134 of the backrest 13, and the second pulley 32 is provided on the force transmission seat 2. The surface of the force transmission seat 2 is parallel to the functional surface 134 of the backrest 13, and the force transmission seat 2 can guide the transmission of force. In addition, the motor 51 can be connected to the force transmission seat 2, thereby indirectly connected to the second pulley 32.

[0060] In some embodiments, a specific connection method between the force transmission seat 2 and the motor 51 is provided. Two pins 21 are fixed on the force transmission seat 2, and the two pins 21 are symmetrical with respect to the longitudinal axis of the force transmission seat 2. The motor 51 is connected to the force transmission seat 2 through a force transmission rope 52. One end of the force transmission rope 52 is a closed loop 521. The closed loop 521 of the force transmission rope 52 is hung on the two pins 21, and the other end is connected to the output end of the motor 51. The connection method between the force transmission rope 52 and the force transmission seat 2 provided in this embodiment ensures that the force transmission rope 52 is evenly stressed, avoids the problem of unilateral overload, and improves the safety of resistance transmission.

[0061] exist Figure 2a-2d In the figure, the force transmission seat 2, the pulley 3, the pull rope 4, etc. arranged on the functional surface 134 of the backrest 13 are shielded by the outer shell to play a protective role; in order to clearly show the matching relationship of the internal components, Figure 3a-Figure 5 The outer shell disposed on the functional surface 134 of the backrest 13 is removed.

[0062] In actual use of the fitness bench, a pull arm 18 is rotatably provided at the upper ends of both sides of the functional surface 134 of the backrest 13. The pull arm 18 is a hollow tubular structure. A guide rope wheel 19 is provided at the lower end of the pull arm 18. The guide rope wheel 19 is axially fixed to the pull arm 18 and rotatably connected to the circumferential direction. The two action ends 41 of the pull rope 4 pass through the interior of the pull arm 18 and are led out through the guide rope wheel 19. The movement of the action end 41 retracting into the interior of the pull arm 18 is restricted, so that the user can apply external force to exercise. Figure 2d As shown, when exercising with the fitness bench in the present application, the tension arm 18 is adjusted to a desired angle, and the user can apply external force to the action end 41 of the pull rope 4, and the motor 51 outputs corresponding resistance according to the selected training mode.

[0063] In some embodiments, Figure 2a , Figure 3b-Figure 5As shown, the fitness bench also includes a controller 61 and an input terminal 62. The controller 61 is connected to the input terminal 62 and the motor 51. The input terminal 62 is used to input control instructions. The controller 61 controls the output force and output form of the motor 51 through the control instructions input by the user at the input terminal 62. This design allows the user to select a suitable resistance level and output mode according to their own training needs, for example, including but not limited to constant resistance, increasing and decreasing resistance cycles, and resistance modes that simulate different exercise scenarios, making the fitness bench more intelligent and personalized.

[0064] In the above embodiment, the mode input of the input terminal 62 can be selected in a variety of forms, such as a button form or a knob form, and the present application does not impose any limitation thereto.

[0065] In addition, it is understandable that since controlling the resistance size and output mode of the motor by means of a controller can be achieved with the help of the prior art, those skilled in the art can design it according to the actual needs of the customer base. This part is not described in detail in the present application, but it should not be considered that the disclosure of this application is insufficient. The connection between the controller 61 and the motor 51 and the input terminal 62 can be an electrical connection or a wired or wireless communication connection, and the present application does not limit the specific connection method. In addition, the various training modes that may be implemented in the present application include, but are not limited to, for example, a concentric mode, an eccentric mode, an elastic mode, and a vibration mode, and users can choose according to their training habits and preferences.

[0066] In some embodiments, Figure 6-7b As shown, the upper surface of the stool body 11 of the fitness stool is covered with a support cover 14 to provide support for the seat cushion 12 and the backrest 13. The support cover 14 includes two side walls 141 arranged along the length direction of the stool body 11 and a bottom plate 142 connecting the bottoms of the two side walls 141. The two side walls 141 and the bottom plate 142 of the support cover 14 define a receiving groove 143 at the top of the stool body 11. When the seat cushion 12 and the backrest 13 are covered on the stool body 11, the receiving groove 143 is closed, providing a neat and safe appearance, while making the fitness stool have the function of a household stool; when the backrest 13 is flipped upward, the receiving groove 143 can be opened to provide additional storage space. Optionally, the support seat is made of metal so that it can provide good support for the seat cushion 12 and the backrest 13 of the fitness stool.

[0067] In some embodiments, Figure 2a and Figure 5As shown, an elastic power rope 53 is arranged in the receiving groove 143, one end of the elastic power rope 53 is connected to the force transmission seat 2, and the other end is connected to the bottom plate 142 of the support cover plate 14, and the elastic power rope 53 is in a tensioned state. The elastic power rope 53 is used as an auxiliary to provide the necessary tension for the pull rope 4, so as to prevent the pull rope 4 from being easily disengaged from the guide rope wheel 19 due to relaxation due to insufficient resistance when the motor 51 is not started or in the initial stage of starting, thereby ensuring the smoothness and continuity of the movement process and improving the stability of the resistance system.

[0068] Optionally, two elastic power ropes 53 may be provided, and the maximum load-bearing kilograms of each elastic power rope 53 is 10kg. In this solution, the elastic power rope 53 can provide the tensioning force necessary for tensioning the pull rope 4, preventing it from loosening when the motor 51 is not started or in the early stage of starting, while ensuring that such tensioning force will not have an adverse effect on the power output by the motor 51 to the pull rope 4.

[0069] In some embodiments, Figure 8a-8c as well as Figure 10-11b As shown, the stool body 11 includes an upper side plate 111 constituting the upper part of both sides of the stool body 11, and a plurality of ribs 112 arranged in the longitudinal direction are arranged near the top on the inner surface of the upper side plate 111. An assembly gap 113 is formed between the top of each rib 112 and the inner surface of the upper side plate 111. The top edge of the side wall 141 of the support cover plate 14 extends outward to form an assembly portion 144, the upper surface of the assembly portion 144 is flush with the top of the upper side plate 111, and the assembly portion 144 is used to support the seat cushion 12 and the back cushion above. The edge of the assembly portion 144 is provided with a downwardly bent mating portion 145, the mating portion 145 is inserted into the assembly gap 113 and the surface of the mating portion 145 is mated with the inner surface of the upper side plate 111, and the assembly portion 144 is supported by the ribs 112.

[0070] Through the structure in the above embodiment, the two side edges of the support cover 14 are limited in the assembly gap 113, so that the support cover 14 and the stool body 11 can be assembled, and the assembly part 144 is supported by the top of the rib 112, which improves the stability and support of the assembly part 144. Even if it is used for a long time, the assembly part 144 will not tilt or sink due to the pressure from above, which will affect the stability of the assembly, thereby improving the stability of the overall structure and extending the service life of the fitness stool.

[0071] In some embodiments, a possible assembly method of the seat cushion 12 is provided by means of the assembly portion 144. Figure 6-7b as well as Figure 9a-9bAs shown, the assembly portion 144 is provided with limiting holes 146, and the bottom surface of the seat cushion 12 is provided with limiting members 71 corresponding to the limiting holes 146.
