Description

Technical Field

[0001] This utility model relates to the field of sports equipment manufacturing technology, and in particular to an automatic cable-laying fitness device. Background Technology

[0002] With people paying increasing attention to their health, more and more fitness equipment has appeared on the market, especially fitness equipment suitable for home use. However, traditional home fitness equipment takes up a lot of space, has limited functions, and is somewhat inconvenient to use.

[0003] Existing portable fitness equipment has limited functionality and is inconvenient to use. It can only perform one intensity of exercise, which reduces its value.

[0004] For example, Chinese patent application CN201910230515.3, titled "Portable Fitness Device," achieves the technical effect described in paragraph

[0018] : "The present invention provides a portable fitness device whose technical effect is achieved by designing the structure between the active wheel and the driven wheel, and by cooperating with the clutch and friction plate, so that the tension of the pull rope can be adjusted, while using hinges to connect the support components makes it easy to carry." This solves the aforementioned technical problems.

[0005] However, it can only be manually rotated by turning the rotating shell (the element that adjusts the tension) to control the tension of the pull rope. Moreover, it lacks an automatic rope winding structure when the pull rope is retracted, resulting in the rope overlapping and becoming tangled. Utility Model Content

[0006] The purpose of this invention is to provide an automatic wire-laying fitness device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: an automatic cable-laying fitness device, characterized in that: The electric adjustment functional structure includes a base as a support, a motor mounting base on the base, a motor assembly mounted on the motor mounting base, a drive gear of the motor assembly connected to the external teeth of a motor transmission gear, an internal tooth of the motor transmission gear connected to the external teeth of an adjustment knob, an internal tooth of the adjustment knob connected to the external teeth of a clutch, and a clutch threadedly connected to a transmission center shaft to convert rotational pressure into lateral pressure, which is then transmitted to a friction clutch assembly. Automatic cable arrangement structure: includes a pull rope for fitness pulling, the pull rope is wound around the outer circumference of a threaded rotating sleeve, the threaded rotating sleeve is threadedly connected to a threaded head, one end of the threaded rotating sleeve is fitted with a rope sleeve to directionally pull out the pull rope, the other end of the threaded rotating sleeve is connected to a rotating connector, and the rotating connector is fixedly connected to a spring assembly that can pre-tighten the pull rope.

[0008] Compared with the prior art, the advantages of this utility model are: by adding an electric adjustment function structure and an automatic cable laying function structure, the tension of the pull rope can be electrically controlled, and the cable can be automatically laid flat when the pull rope is retracted.

[0009] As an improvement of this utility model, the threaded rotating sleeve is provided with an elongated groove, and the rotating connector is provided with a rib that matches the elongated groove. The purpose of this design is that the rib is placed in the elongated groove, which can drive both to rotate synchronously without affecting the left and right (lateral) movement of the threaded rotating sleeve.

[0010] As an improvement to this utility model, the friction clutch assembly includes several disc-shaped friction plates, with a small metal plate fixed between each pair of friction plates for transmitting power. The purpose of this design is that the friction plates are made of flexible material with a certain degree of compressibility, and the small metal plate transmits power to the valve core. When the pressure is increased by adjusting the button, the force pressing down on the friction plates is greater, thus requiring a greater force to rotate the small metal plate (ultimately resulting in a greater force being needed on the pull rope, as the pull rope and the small metal plate are rigidly connected at this point).

[0011] As an improvement of this utility model, the inner cavity of the friction clutch assembly is fixedly connected to the outer periphery of the transmission center shaft. The purpose of this design is that the transmission center shaft serves as the adjustment and support center of the entire structure, with one end connected to the clutch via a thread, and the other end fitted with the friction clutch assembly.

[0012] As an improvement of this utility model, a friction plate is provided under the base. The purpose of this design is to increase the friction between the automatic cable-laying fitness device and the supporting surface (such as the ground or wall, the automatic cable-laying fitness device can be placed in different places).

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example 1 Please refer to Figure 1 -9.

[0026] This embodiment provides an automatic cable-laying fitness device, including a base 1, a top cover 25, and a battery assembly 26 that provides power. It is characterized by including an electric adjustment function structure and an automatic cable-laying function structure.

[0027] In the embodiments of this utility model application, please refer to Figure 2 and Figure 3 .

[0028] Electric adjustment function structure: A motor mounting base 2 is provided on the base 1, and a motor assembly 3 is mounted on the motor mounting base 2. The drive gear 4 of the motor assembly 3 is connected to the external teeth of the motor transmission gear 5. The internal teeth of the motor transmission gear 5 are connected to the external teeth of the adjustment knob 6. The internal teeth of the adjustment knob 6 are connected to the external teeth of the clutch 7. The first internal thread 27 of the clutch 7 is threadedly connected to the transmission center shaft 8, converting rotational pressure into lateral pressure, which is transmitted to the friction clutch assembly 9. A spring 24 is installed on the adjustment knob 6. Under normal conditions, the automatic cable-laying fitness device is in electric transmission mode. When operating manually, the adjustment knob 6 needs to be pressed in to connect to the power structure.

[0029] In the embodiments of this utility model application, please refer to Figure 4 and Figure 5 .

[0030] Automatic cable arrangement structure: includes a pull rope 10 for fitness pulling, the pull rope 10 is wound around the outer circumference of a threaded rotating sleeve 11, the second internal thread 28 of the threaded rotating sleeve 11 is threadedly connected to a threaded head 22, one end of the threaded rotating sleeve 11 is fitted with a rope sleeve 12 for directional pulling of the pull rope 10, and the other end of the threaded rotating sleeve 11 is connected to a rotating connector 13, the rotating connector 13 is fixedly connected to a spring assembly 14 that can pre-tighten the pull rope 10.

[0031] In the embodiments of this utility model application, please refer to Figure 8 and Figure 9 The threaded rotating sleeve 11 is provided with an elongated groove 15, and the rotating connector 13 is provided with a raised rib 16 that matches the elongated groove 15. The raised rib 16 is placed in the elongated groove 15, which can drive both to rotate synchronously without affecting the left and right (lateral) movement of the threaded rotating sleeve 11.

[0032] In the embodiments of this utility model application, please refer to Figure 7The friction clutch assembly 9 includes several disc-shaped friction plates 17, with a small metal plate 18 for transmitting power fixed between every two friction plates 17. The friction plates 17 are made of flexible material and have a certain degree of compressibility. The small metal plate 18 transmits power to the valve core 23. When the pressure is increased by the adjustment button, the clutch 7 squeezes the end face 19 of the friction clutch assembly 9, thereby increasing the force of the compression spring 20 pressing the friction plates 17. This, in turn, requires a greater force to rotate the small metal plate 18 (ultimately reflected in the pull rope 10, as the pull rope 10 and the small metal plate 18 are rigidly connected at this time). The specific power transmission is as follows: the pull rope 10 drives the threaded rotating sleeve 11, the threaded rotating sleeve 11 drives the rotating connecting member 13 (with a spring assembly 14 inside), the rotating connecting member 13 drives the valve core 23, and the valve core 23 drives the small metal plate 18. Therefore, the greater the resistance of the small metal plate 18, the greater the pulling force required to pull the pull rope 10, thus achieving the adjustment between different pulling forces. It should be noted that when the pull cord 10 is released, it automatically retracts under the preload of the spring assembly 14. Furthermore, a one-way bearing is installed in the middle; when the pull cord 10 is pulled out, the one-way bearing can transmit power, and when the pull cord 10 is released, the one-way bearing disconnects the power. This is prior art (refer to the comparative documents in the background section), and will not be elaborated upon here.

[0033] Furthermore, the inner cavity of the friction clutch assembly 9 is fixedly connected to the outer periphery of the transmission center shaft 8. The transmission center shaft 8 serves as the adjustment support center of the entire structure, with one end connected to the clutch 7 via a thread, and the other end fitted with the friction clutch assembly 9.

[0034] In the embodiments of this utility model application, please refer to Figure 1 A friction plate 21 is provided under the base 1 to increase the friction between the automatic cable-laying exercise device and the supporting surface (such as the ground or wall, the automatic cable-laying exercise device can be placed in different places).

[0035] This embodiment provides an automatic cable-laying fitness device, which is connected as follows.

[0036] Electric adjustment structure: A motor mounting base 2 is provided on the base 1, and a motor assembly 3 is mounted on the motor mounting base 2. A drive gear 4 is fixed on the output shaft of the motor assembly 3. The motor transmission gear 5 is provided with external teeth and internal teeth. The drive gear 4 is connected to the external teeth of the motor transmission gear 5. The internal teeth of the motor transmission gear 5 are then connected to the external teeth of the adjustment knob 6. The adjustment knob 6 is also provided with internal teeth. The internal teeth of the adjustment knob 6 are connected to the external teeth of the clutch 7. The clutch 7 is threadedly connected to the transmission center shaft 8, converting rotational pressure into lateral pressure, which is transmitted to the friction clutch assembly 9.

[0037] Automatic cable laying function structure: Since the threaded rotating sleeve 11 is threadedly connected to the threaded head 22, when the pull rope 10 is pulled out, the threaded rotating sleeve 11 will move to the left under the rotational force of the pull rope 10. When the pull rope 10 is released, the pull rope 10 will automatically retract under the preload of the spring assembly 14. At this time, the thread will rotate to the right, and the pull rope 10 can be wound flat on the threaded rotating sleeve 11.

[0038] This embodiment provides an automatic cable-laying fitness device. During normal use, pressing the adjustment knob 6 disengages it from the motor drive gear 5, allowing manual rotation of the knob to select different speed levels. Additionally, by connecting the sensing carbon plate on the adjustment knob 6 to the carbon brush PCB (the control computer board of the automatic cable-laying fitness device), different speed levels can be displayed on the app.

[0039] Electric adjustment function: The motor is connected to the APP via the carbon brush PCB (the control computer board of the automatic cable-laying fitness machine). The APP controls the forward and reverse rotation of the motor, and the motor drives the adjustment knob 6 to rotate forward or backward through the motor transmission gear 5, thereby selecting different gear levels. At the same time, the sensing carbon plate on the adjustment knob 6 contacts the carbon brush PCB (the control computer board of the automatic cable-laying fitness machine), and the different gear levels are displayed on the APP.

[0040] The beneficial effects of this utility model are as follows: by adding an electric adjustment function structure and an automatic cable laying function structure, the tension of the pull rope 10 can be electrically controlled, and the cable can be automatically laid flat when the pull rope 10 is retracted.
