Technical Field
[0001] This utility model relates to the technical field of fitness equipment, and in particular to a novel fitness device that is easy to assemble and disassemble. Background Technology
[0002] With the popularization of home fitness equipment, resistance bands have gradually become a common home fitness device due to their advantages such as flexible exercise modes and small footprint. To achieve the resistance adjustment function, existing home resistance bands are generally equipped with a resistance winding motor and a resistance rope. The core of the resistance band works through the coordinated operation of motor resistance control, spring energy storage, and one-way bearing. When in use, the user pulls the resistance rope, and the winding device rotates with the rope. Through the one-way bearing, it rotates synchronously with the resistance winding motor. The motor simulates training resistance with reverse torque. After releasing the rope, the spring in the winding device releases elastic potential energy, driving the resistance rope to automatically rewind, thus completing the resistance training.
[0003] Currently, most resistance training machines on the market require a separate cavity outside the machine casing to house the resistance motor and resistance rope in order to install them. For example, Chinese Patent No. CN221964408U provides a novel 180-degree foldable fitness machine, which includes a shell, a rotating component, a base plate, a resistance cable take-up device, a training rope, a tension component, an electronic control component, and a battery component. Two shells are provided, with one end of each shell rotatably connected to both ends of the rotating component. A rotation amplitude limiting structure is provided between the hinge point of each shell and the rotating component. The resistance cable take-up devices are respectively located on the top surfaces of the two shells. One end of each training rope is wound around its corresponding resistance cable take-up device, and the other end of the training rope extending from the resistance cable take-up device is connected to the tension component. Each shell has an internal cavity, and the electronic control component and battery component are respectively located within the two cavities. Both the electronic control component and battery component are electrically connected to the two resistance cable take-up devices. The base plate is fixedly located at the bottom of each shell. This patent uses a separate outer cover and housing (housing cavity) on the top surface of the outer shell to house the resistance winding motor. However, this design has the following drawbacks: 1. Because the resistance winding motor is enclosed by the outer cover, disassembly and assembly must begin with separating the outer cover and then reassembling the housing, making disassembly and maintenance cumbersome and costly. 2. The wiring between the motor and the bottom battery assembly must pass through the housing cavity, resulting in complex wiring paths that can easily lead to short circuits or poor contact, increasing assembly and maintenance costs. 3. The motor is located inside a separate, protruding outer cover and housing, separated from the base of the fitness equipment. This results in insufficient rigidity in the connection between the motor and the base, essentially disrupting the rigid transmission chain of "motor force → base bearing → ground dispersion." This leads to unstable resistance output when the user pulls the resistance rope, accelerated fatigue of the connection structure between the housing and the outer cover, decreased overall stability, and increased torque load at the hinge points between the housing and rotating parts. Long-term use can easily cause the housing to crack, resulting in a short service life, which urgently needs to be addressed. Utility Model Content
[0004] In view of the shortcomings of the prior art, this application provides a new type of fitness device that is easy to assemble and disassemble.
[0005] The above-mentioned inventive objective of this application is achieved through the following technical solutions:
[0006] A novel fitness device that is easy to assemble and disassemble includes a base, a shell, and a rotating shaft. Two bases and two shells are symmetrically arranged, with the bases corresponding to the bottom of the shells. The two shells are rotatably connected to both ends of the rotating shaft. The shell includes a motor part and a foot pedal part connected horizontally in sequence. The shell and the base are detachably and fixedly connected and form a cavity. A resistance winding motor and a battery assembly are detachably and fixedly connected in the cavity corresponding to the position of the motor part. The resistance winding motor is equipped with a tension rope. The motor part has a winding hole corresponding to the resistance winding motor. The tension rope is wound into the winding wheel of the resistance winding motor through the winding hole. The position in the cavity corresponding to the foot pedal part is used for the passage of the cable.
[0007] Preferably, the motor and the foot pedal are fixedly connected by being made as a single piece.
[0008] Preferably, the motor end is provided with a first lap joint, the foot pedal end is provided with a first lap groove corresponding to the position of the first lap joint, the foot pedal end is provided with a second lap groove, and the motor end is provided with a second lap joint corresponding to the position of the second lap groove. When the housing is connected to the base, the first lap joint and the first lap groove, as well as the second lap joint and the second lap groove, are lapped together.
[0009] Preferably, a motor support is provided on the base corresponding to the position of the motor part, and a mounting shaft extends horizontally on the motor support. The resistance take-up motor is sleeved on the mounting shaft. A battery bracket is provided on the base corresponding to the position of the motor part. A battery cavity for placing the battery assembly is formed between the base and the battery bracket. The motor support is located directly above the battery bracket. Both the motor support and the battery bracket have wire through holes for wires to pass through. A battery mounting port and a detachable battery mounting cover are provided on the bottom of the base corresponding to the position of the battery cavity.
[0010] Preferably, when the resistance take-up motor is sleeved on the mounting shaft, the resistance take-up motor and the motor support are fixed by three screws, which are spaced 120° apart.
[0011] Preferably, the motor support and the base are fixedly connected by a threaded connection or by welding.
[0012] Preferably, a cooling fan is provided in the cavity corresponding to the position of the motor section, and the cooling fan is detachably mounted on the top of the battery bracket. The cooling fan is used to dissipate heat from the resistance winding motor, and the motor section has several heat dissipation holes corresponding to the position of the cooling fan.
[0013] Preferably, the outer shell is made of plastic, while the base, motor bracket, and battery holder are all made of metal and have undergone anodizing and spraying treatment.
[0014] Preferably, a first strip-shaped limiting hole is provided on the top of the motor section, and a limiting slide is fixedly connected to the inner side of the motor section corresponding to the position of the first strip-shaped limiting hole. A second strip-shaped limiting hole is provided on the limiting slide, the second strip-shaped limiting hole is connected to the first strip-shaped limiting hole and is located directly below the first strip-shaped limiting hole. A slide plate is slidably connected to the limiting slide, and a wire take-up hole is provided on the slide plate.

[0015] Preferably, when the outer shell is connected to the base, the bottom surface of the outer shell is flush with the bottom surface of the base.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By symmetrically arranged base and shell, and rotatably connected by a pivot, a flexible and operable resistance training device is formed. By placing the resistance winding motor and battery assembly in the cavity enclosed by the shell and base, no other components need to be disassembled when disassembly or assembly is required. Only the shell needs to be separated for inspection or disassembly, simplifying the disassembly and assembly process. Furthermore, the wires of the resistance winding motor and battery assembly in the corresponding motor section within the cavity can be rationally arranged through the foot pedal position, avoiding the complex path of the wires running through the shell cavity. At the same time, the resistance winding motor, battery assembly, and other components are stably connected to the base through motor supports and battery brackets, forming an integral part with the base. During training, a rigid transmission chain of "motor force → base bearing → ground dispersion" can be completed, avoiding the problem of unstable resistance output caused by the separation of the motor and base, reducing the risk of shell cracking, and extending the service life of the fitness device.

[0027] The following is a reference appendix. Figure 1 To be continued Figure 6 This application describes a novel fitness device that is easy to assemble and disassemble.
[0028] Reference Figures 1 to 6 The new type of fitness equipment, which is easy to assemble and disassemble, includes a base 1, a shell 2, and a rotating shaft 3. Two bases 1 and two shells 2 are symmetrically arranged, with the base 1 corresponding to the bottom of the shell 2. The two shells 2 are rotatably connected to both ends of the rotating shaft 3. The shell 2 includes a motor part 21 and a foot pedal part 22 connected horizontally in sequence. The shell 2 and the base 1 are detachably and fixedly connected, forming a receiving cavity 4. Specifically, the shell 2 and the base 1 are detachably and fixedly connected by a threaded connection. A resistance winding motor 5 and a battery assembly 6 are detachably and fixedly connected within the receiving cavity 4, corresponding to the position of the motor part 21. The resistance winding motor 5 is equipped with a tension rope 7, and the motor part 21 corresponds to the resistance winding... A take-up hole 8 is provided at the motor 5. The tension rope 7 is wound up to the take-up wheel 9 of the resistance take-up motor 5 through the take-up hole 8. The position of the foot pedal 22 in the accommodating cavity 4 is used for the passage of the wire. The symmetrically arranged base 1 and the outer shell 2 form a rotatable integral structure through the pivot 3. The motor part 21 of the outer shell 2, the foot pedal 22 and the base 1 surround the accommodating cavity 4, so that the resistance take-up motor 5, battery pack 6 and other components are integrated in the accommodating cavity 4. The tension rope 7 is wound up in an orderly manner through the take-up hole 8. The wire is neatly arranged at the corresponding position of the foot pedal 22. This structural layout avoids the need for an external structure of the resistance take-up motor 5, simplifies the disassembly and assembly process and improves the structural stability.
[0029] It should be noted that the rotating shaft 3, the resistance winding motor 5, the winding reel 9, the battery assembly 6, and other structures are all conventional structural components of resistance training equipment on the market, and their working principles are common knowledge to those skilled in the art, and will not be restricted or elaborated here.
[0030] Preferably, in one embodiment, the motor part 21 and the foot pedal part 22 are fixedly connected by being integrally formed. By making the motor part 21 and the foot pedal part 22 integrally, the two form an integral structure without connection gaps, thereby enhancing the structural rigidity of the housing 2. At the same time, the status of all the devices connected to the base 1 can be checked simply by separating the integral housing 2, improving the convenience of disassembly and assembly.
[0031] In another embodiment, the motor part 21 extends to the end with a first lap joint 10, the foot pedal part 22 is provided with a first lap groove 11 corresponding to the position of the first lap joint 10, the foot pedal part 22 extends to the end with a second lap groove 13, and the motor part 21 is provided with a second lap joint 12 corresponding to the position of the second lap groove 13. When the outer shell 2 is connected to the base 1, the first lap joint 10 and the first lap groove 11, as well as the second lap joint 12 and the second lap groove 13, are all lapped together. The motor part 21 and the foot pedal part 22 can form an interlocking structure through the lap joint and the lap groove, which facilitates the positioning connection between the base 1 and the motor part 21 and the foot pedal part 22. This is suitable for the case where the motor part 21 and the foot pedal part 22 are connected separately. Furthermore, by adopting the method of connecting the motor part 21 and the foot pedal part 22 separately, when it is necessary to check the working condition of the motor, only the motor part 21 needs to be removed.
[0032] Preferably, a motor support 14 is provided on the base 1 at the position corresponding to the motor part 21, and a mounting shaft 15 extends horizontally from the motor support 14. The resistance take-up motor 5 is sleeved on the mounting shaft 15. A battery bracket 16 is provided on the base 1 at the position corresponding to the motor part 21. A battery cavity for placing the battery assembly 6 is formed between the base 1 and the battery bracket 16. The motor support 14 is located directly above the battery bracket 16. Both the motor support 14 and the battery bracket 16 have wire-passing holes 17 for wires to pass through. A battery mounting port 18 and a detachable battery mounting cover 19 are provided on the bottom of the base 1 at the position corresponding to the battery cavity. Specifically, the battery mounting cover 19 can be detachably connected to the base by means of a threaded connection. 1. At the bottom, the motor support 14 of the base 1 is positioned by the mounting shaft 15 to connect the resistance take-up motor 5. The battery bracket 16 cooperates with the base 1 to form a battery cavity to accommodate the battery assembly 6. The wire hole 17 allows the wire to pass through centrally. The battery mounting port 18 and the mounting cover facilitate the installation and removal of the battery. This enables modular installation and centralized management of the resistance take-up motor 5 and the battery assembly 6, and makes the resistance take-up motor 5, battery assembly 6 and other components integrated with the base 1. During training, a rigid transmission chain of "motor force → base 1 bearing → ground dispersion" can be completed, which can avoid the problem of unstable resistance output caused by the separation of the motor and the base 1, reduce the risk of cracking of the outer shell 2, and extend the service life of the fitness equipment.
[0033] Furthermore, when the resistance take-up motor 5 is sleeved on the mounting shaft 15, the resistance take-up motor 5 and the motor support 14 are fixed by three screws 20, which are spaced 120° apart. The three screws 20 spaced 120° apart fix the resistance take-up motor 5 and the motor support 14 to complete the detachable installation of the resistance take-up motor 5 after it is sleeved and positioned on the mounting shaft 15 of the motor support 14. This can avoid excessive force at a single point, prevent the motor from loosening due to vibration or tension, and ensure stable resistance output.
[0034] In addition, the motor support 14 and the base 1 are fixedly connected by thread or welding. The threaded connection allows for flexible disassembly and assembly, while the welding method enhances the fixing strength. Technicians can adapt the method according to the needs of different scenarios.
[0035] In addition, a cooling fan 23 is provided in the cavity 4 corresponding to the position of the motor part 21, and the cooling fan 23 is detachably mounted on the top of the battery bracket 16. Specifically, the cooling fan 23 can be detachably mounted on the top of the battery bracket 16 by means of a threaded connection. The cooling fan 23 is used to dissipate heat from the resistance take-up motor 5. The motor part 21 has several heat dissipation holes 24 at the position corresponding to the cooling fan 23. The cooling fan 23 blows air to dissipate heat from the resistance take-up motor 5 in the cavity 4, and the heat dissipation holes 24 enable air circulation and timely dissipation of the heat generated by the generator operation, so as to avoid the motor from overheating and causing performance degradation or damage, and improve the reliability of equipment operation.
[0036] Preferably, the outer shell 2 is made of plastic, while the base 1, motor support 14, and battery bracket 16 are all made of metal and have undergone anodizing and spraying treatment. The use of plastic shell 2 can reduce the overall weight, while the use of metal base 1, motor support 14, and battery bracket 16 can ensure structural strength. The anodizing and spraying treatment enhances corrosion resistance, which can balance the portability and durability of the resistance training equipment and extend the service life of the equipment.
[0037] Preferably, to meet the needs of different pulling directions during training, the motor part 21 has a first strip-shaped limiting hole 25 on its top. A limiting slide 26 is fixedly connected to the inner side of the motor part 21 corresponding to the position of the first strip-shaped limiting hole 25. A second strip-shaped limiting hole 27 is provided on the limiting slide 26. The second strip-shaped limiting hole 27 is connected to the first strip-shaped limiting hole 25 and is located directly below the first strip-shaped limiting hole 25. A slide plate 28 is slidably connected to the limiting slide 26. A cable take-up hole 8 is provided on the slide plate 28. A limiting ring 29 is provided on the slide plate 28 corresponding to the position of the cable take-up hole 8. The limiting ring 29 is located inside the first strip-shaped limiting hole 25 and is used to abut against the end wall of the first strip-shaped limiting hole 25. The slide plate 28 can adjust the position of the cable take-up hole 8 by sliding along the limiting slide 26. The limiting ring 29 abuts against the end wall of the first strip-shaped limiting hole 25 to limit the sliding range, so as to adapt to the user's needs for different pulling directions and prevent the slide plate 28 from falling off, thereby improving the flexibility and safety of use.
[0038] It should be noted that technicians can control the angular range of the pulling force direction by adjusting the design length of the first strip-shaped limiting hole 25 and the second strip-shaped limiting hole 27, which will not be elaborated here.
[0039] Preferably, when the outer shell 2 is connected to the base 1, the bottom surface of the outer shell 2 is flush with the bottom surface of the base 1, so that the outer shell 2 can wrap around the outside of the base 1. When the fitness equipment is placed on the ground, it can shield and protect the base 1, and at the same time, the overall force of the equipment is evenly distributed on the ground, enhancing the stability of the fitness equipment when it is placed.
[0040] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
