Description

Technical Field

[0001] This utility model relates to the field of electronically controlled fitness equipment technology, specifically to a rope-pulling power box that can quickly retract ropes. Background Technology

[0002] Electrically controlled fitness equipment typically uses the forward and reverse rotation of a motor to control the release and retraction of resistance bands. However, existing control motors rotate forward to release the resistance band when it is pulled out quickly, and when the resistance band is released, the motor needs to switch from forward to reverse to retract the band. If the resistance band is pulled out quickly and then released, the motor has inertia when switching between forward and reverse rotation, and the motor retracts the band slowly in reverse. This results in the resistance band not being able to tighten quickly, the resistance band being prone to loosening, causing the rope arrangement to become messy, and poor consistency in the user experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rope power box with a simple structure, which keeps the tension rope in a taut state, avoids messy arrangement, and improves the user experience by allowing for quick rope winding.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A pull rope power box with rapid rope retraction includes a housing, in which a drive motor and an auxiliary rope retraction mechanism are provided. A tension rope is wound on the drive motor, and the other end of the tension rope is connected to the auxiliary rope retraction mechanism. The initial tension of the drive motor when releasing the rope is greater than that of the auxiliary rope retraction mechanism. The auxiliary rope retraction mechanism is used to assist in retracting the tension rope when the drive motor switches between forward and reverse rotation.

[0006] As a further improvement to the above technical solution:

[0007] The auxiliary rope winding mechanism includes a support base, a winding wheel, a rotary transmission component, and an elastic component. The support base is located inside the housing. The winding wheel is rotatably mounted on the support base. The tension rope is connected to the winding wheel. The elastic component is located on the support base. One end of the rotary transmission component is connected to the elastic component, and the other end is connected to the shaft of the winding wheel.

[0008] The rotary transmission component is arranged perpendicular to the shaft of the winding wheel.

[0009] The support base is a U-shaped support base, the winding wheel is located on the inner side of the support base, and the elastic element is located on the outer side of the support base.

[0010] The support base is detachably connected to the housing.

[0011] The elastic element is a coil spring.

[0012] The housing is provided with a first rope outlet and a second rope outlet. The middle part of the tension rope passes through the first rope outlet and then through the second rope outlet. The housing is also provided with a rope guide assembly, which is located between the first rope outlet and the drive motor. The output direction of the rope guide assembly coincides with the center line of the first rope outlet.

[0013] The center line of the second rope outlet is tangent to the winding wheel.

[0014] The housing contains a control module, which is electrically connected to the drive motor.

[0015] The control module is connected to a heat dissipation resistor.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This utility model discloses a rope-pulling power box with rapid rope retraction. Because the initial tension of the drive motor on the rope during rope release is greater than the initial tension of the elastic auxiliary rope-pulling mechanism, the elastic auxiliary rope-pulling mechanism remains under tension during rope release. At this time, the rope is wound around the drive motor, while the elastic auxiliary rope-pulling mechanism is not wound around the rope. When the rope is quickly pulled outwards and released, the drive motor is in the process of changing from forward to reverse direction. Due to inertia, the tension on the rope is weak. At this time, the elastic auxiliary rope-pulling mechanism... The auxiliary rope winding mechanism uses the rebound force to wind and wind the tension rope, ensuring that the tension rope remains taut even when the drive motor is in operation. This prevents the tension rope from becoming loose and causing a messy arrangement, improving the user experience. When the drive motor completes the reversal from forward to reverse, and the tension on the tension rope after reversal is greater than that of the elastic auxiliary rope winding mechanism, the tension rope wound on the elastic auxiliary rope winding mechanism is wound back onto the drive motor. At this point, the elastic auxiliary rope winding mechanism returns to its initial taut state, facilitating the next assistance. Attached Figure Description

[0028] Figures 1 to 5 This invention illustrates one embodiment of a fast-retractable rope power box. The fast-retractable rope power box of this embodiment includes a housing 1, within which a drive motor 2 and an elastic auxiliary rope-retracting mechanism 3 are provided. A tension rope 4 is wound around the drive motor 2, and the other end of the tension rope 4 is connected to the elastic auxiliary rope-retracting mechanism 3. When releasing the rope, the initial tension of the drive motor 2 on the tension rope 4 is greater than that of the elastic auxiliary rope-retracting mechanism 3. The elastic auxiliary rope-retracting mechanism 3 is used to assist in retracting the tension rope 4 when the drive motor 2 switches between forward and reverse rotation.

[0029] This fast-retracting rope power box works because the initial tension of the drive motor 2 on the tension rope 4 during rope release is greater than the initial tension of the elastic auxiliary rope retraction mechanism 3 on the tension rope 4. Therefore, the elastic auxiliary rope retraction mechanism 3 is always under tension during rope release, and the tension rope 4 is wound around the drive motor 2, while the elastic auxiliary rope retraction mechanism 3 is not wound with the tension rope 4. When the tension rope 4 is quickly pulled outwards and released, the drive motor 2 is in the process of changing from forward to reverse direction. Due to inertia, the tension on the tension rope 4 is weak, and the elastic auxiliary rope retraction mechanism 3... The rope mechanism 3 uses the rebound tension to wind and retract the tension rope 4, ensuring that the tension rope 4 remains taut even when the drive motor 2 is in a changing state. This prevents the tension rope 4 from becoming loose and causing a messy arrangement, thus improving the user experience. When the drive motor 2 completes the change from forward to reverse, and the tension on the tension rope 4 after the reverse rotation is greater than that of the elastic auxiliary winding mechanism 3, the tension rope 4 wound on the elastic auxiliary winding mechanism 3 is wound back onto the drive motor 2. At this time, the elastic auxiliary winding mechanism 3 returns to its initial taut state, facilitating the next assistance.

[0030] Furthermore, in this embodiment, the elastic auxiliary rope winding mechanism 3 includes a support base 31, a winding wheel 32, a rotary transmission component 33, and an elastic component 34. The support base 31 is disposed inside the housing 1. The winding wheel 32 is rotatably mounted on the support base 31. The tension rope 4 is connected to the winding wheel 32. The elastic component 34 is disposed on the support base 31. One end of the rotary transmission component 33 is connected to the elastic component 34, and the other end is connected to the shaft of the winding wheel 32. The winding wheel 32 is used to connect and wind the tension rope 4. The rotary transmission component 33 realizes the transmission between the winding wheel 32 and the elastic component 34, thereby realizing that when the winding wheel 32 rotates to the initial state, the elastic component 34 is stretched and tightened, and the rebound force of the elastic component 34 drives the winding wheel 32 to rotate and wind the rope. The structure is simple and ingenious.

[0031] Furthermore, in this embodiment, the rotary transmission component 33 is arranged perpendicularly to the shaft of the winding wheel 32. This results in a more compact structure.

[0032] Furthermore, in this embodiment, the elastic element 34 is a coil spring. This better accommodates the structural arrangement where the rotary transmission element 33 and the winding wheel 32 are arranged perpendicularly to each other, resulting in a more compact structure.

[0033] Furthermore, in this embodiment, the support base 31 is a U-shaped support base, the winding wheel 32 is located on the inner side of the support base 31, and the elastic element 34 is located on the outer side of the support base 31. This facilitates the arrangement of the winding wheel 32 and the elastic element 34.

[0034] Furthermore, in this embodiment, the support base 31 is detachably connected to the housing 1, facilitating the assembly and disassembly of the elastic auxiliary rope winding mechanism 3.

[0035] Furthermore, in this embodiment, the housing 1 is provided with a first rope outlet 11 and a second rope outlet 12. The middle part of the tension rope 4 passes through the first rope outlet 11 and then passes through the second rope outlet 12. The housing 1 is also provided with a rope guide assembly 5, which is located between the first rope outlet 11 and the drive motor 2. The rope feeding direction of the rope guide assembly 5 coincides with the center line of the first rope outlet 11. Specifically, one end of the tension rope 4 is wound around the drive motor 2, and the other end passes through the first rope outlet 11 and then the second rope outlet 12, finally connecting to the winding reel 32. At this point, a section of the tension rope 4 is located outside the housing 1 for easy pulling and releasing. Due to the large size of the drive motor 2, it is difficult for the center line of the first rope outlet 11 to be aligned with the conveying direction of the drive motor 2; there is usually a certain angle between them. This causes friction between the tension rope 4 and the first rope outlet 11, affecting the service life of the tension rope 4. A rope guide assembly 5 is provided between the first rope outlet 11 and the drive motor 2 to change the conveying direction of the tension rope 4, so that the conveying direction of the tension rope 4 after passing through the rope guide assembly 5 is aligned with the center line of the first rope outlet 11, reducing friction with the first rope outlet 11 and improving the service life of the tension rope 4. Preferably, the rope guide assembly 5 is located close to the first rope outlet 11.

[0036] Furthermore, in this embodiment, the center line of the second rope outlet 12 is tangent to the winding wheel 32. That is, the rope feeding direction of the winding wheel 32 coincides with the center line of the second rope outlet 12, which helps to reduce the friction between the tension rope 4 and the second rope outlet 12.

[0037] Furthermore, in this embodiment, a control module 6 is provided inside the housing 1, and the control module 6 is electrically connected to the drive motor 2. The control module 6 is electrically connected to the drive motor 2, which facilitates the control of the forward and reverse rotation and the pulling force of the drive motor 2. It should be noted that this type of electrical connection is a common technology in electrically controlled fitness equipment.

[0038] Furthermore, in this embodiment, the control module 6 is connected to a heat dissipation resistor 7. This facilitates heat dissipation and ensures the normal operation of the control module 6.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
