Description

Technical Field

[0001] This application relates to the technical field of fitness equipment, and particularly relates to a dual-digital magnetic powder damper power station. Background Art

[0002] Power-type fitness equipment mainly consists of two major parts: an operating mechanism and a counterweight mechanism. The operating mechanism has its own corresponding special structure according to the position of the muscle being trained, while the counterweight mechanism is mostly basically the same in a series of products. However, most counterweight mechanisms are large in volume and heavy in weight, and are not suitable for small fitness equipment, which is not conducive to the popularization of fitness equipment.

[0003] Currently, more and more electronically controlled resistance mechanisms have emerged to replace traditional counterweight mechanisms. However, the current electronically controlled resistance mechanisms, such as the resistance system composed of magnetic powder brakes, mostly adopt a single resistance source form, resulting in the inability to perform single-handed training. Moreover, an additional special motor is required to assist in wire winding, which is costly and has great limitations. Therefore, there is an urgent need for a dual-digital magnetic powder damper power station that can reduce costs and facilitate single-handed training. Utility Model Content

[0004] The purpose of this application is to provide a dual-digital magnetic powder damper power station for the above problems existing in the prior art.

[0005] To achieve the above application purpose, the following technical solutions are adopted in this application: The dual-digital magnetic powder damper power station includes:

[0006] A frame, the outer surface of which is covered with a housing. The two ends of the housing in the length direction are provided with wire outlet ports, and a convex cavity is provided in the middle part. The convex cavity is used to install a damping structure and a control end;

[0007] Among them, the two ends of the housing in the length direction are provided with foot pedal areas;

[0008] A damping structure, including a magnetic powder brake for providing resistance and a wire winding assembly drivingly connected to the magnetic powder brake. The magnetic powder brake and the wire winding assembly are a pair, and two pairs are symmetrically arranged to form a damping structure; a wire winding groove is provided on each wire winding assembly, and each wire winding assembly provides a wire winding force through an internal coil spring;

[0009] Pull handles, which are respectively connected to each wire winding assembly through a wire and a wire winding wheel set. The wire passes through the wire outlet port to connect to the pull handle;

[0010] A control end, communicatively connected to the damping structure;

[0011] A rotational speed sensor, communicatively connected to the control end, is provided on one side of the wire winding assembly and is used to detect the rotational speed of the wire winding assembly.

[0012] Working principle and beneficial effects: 1. Compared with the prior art, through two pairs of magnetic powder brakes - wire winding assemblies of the damping structure in this application, in cooperation with two pull handles, the two systems can operate independently, and the left and right wire winding do not interfere with each other. Therefore, single - hand training and two - hand training can be achieved.

[0013] 2. Compared with the prior art, when the user uses it, pulling the pull handle with one hand or both hands, the pull handle drives the wire. When the wire is stretched, the torsion spring of the wire winding assembly will wind up and store elastic force. After releasing the wire, the torsion spring provides the wire winding force, thus eliminating the need for an additional motor to provide the wire winding force, significantly reducing the cost and making the structure more compact, which can be applied to smaller fitness equipment and is thus convenient for popularization.

[0014] 3. Compared with the prior art, this application can detect the rotation speed of the wire winding assembly through a rotation speed sensor, thereby providing basic data for subsequent calculation of the user's motion data (such as output speed).

[0015] Furthermore, it also includes a battery disposed in the convex cavity, and the battery is electrically connected to the control end. In this way, it is not restricted by the length of the wire and the position of the socket, greatly improving the flexibility of use of this strength station and enabling it to be used in more scenarios.

[0016] Furthermore, a driven wheel is provided on the wire winding assembly, and a driving wheel is provided on the magnetic powder brake. The driven wheel and the driving wheel are driven and connected by a belt or a chain. Since the driving wheel and the magnetic powder brake are separated, maintenance becomes easier and more economical. The parts that need to be repaired or replaced can be accessed independently without affecting the operation of the entire system.

[0017] Furthermore, each wire winding assembly includes a wire winding body provided with a wire winding groove, a torsion spring disposed in the installation groove of the wire winding groove, a front cover for closing the wire winding groove, and a one - way bearing partially disposed on the inner ring of the wire winding body. The two wire winding assemblies are both connected to the same main shaft. The two ends of the main shaft respectively pass through the two wire winding assemblies and are coaxially rotationally connected to each torsion spring through a fixed bushing. Each driven wheel is connected to the main shaft through a one - way bearing. The presence of the torsion spring enables it to automatically wind the rope back into the wire winding groove when the wire is released, thus realizing an automatic wire winding process. The use of the one - way bearing allows the driven wheel to be connected to the main shaft, but only allows one - way rotation. Therefore, when the wire is released, the torsion spring only drives the main shaft and the wire winding body to rotate, but does not drive the driven wheel to rotate. That is, the user can freely stretch the wire. When the user relaxes, the one - way bearing will prevent the driven wheel from rotating, thus preventing the wire winding from being unable to be completed due to the damping of the magnetic powder brake.

[0018] Further, the rotational speed sensor includes a magnet disposed on the winding body and a magnetic inductor mounted on the inner wall of the housing. The magnetic inductor can detect the magnetic field change when the magnet passes by, causing the movement of charges in the magnetic inductor. The movement of these charges generates an electric current signal. The frequency of this signal is proportional to the rotational speed of the winding body. By measuring the frequency of this electric current signal, the rotational speed of the winding body can be calculated, and then converted into digital data such as speed and distance. After a series of conversions like this, training parameters such as the user's output speed can be calculated (the specific conversions are prior art and not the protected technical points of this application).

[0019] Further, each winding wheel group includes a first winding wheel, a steering wheel, and a second winding wheel. The pulling wire passes through the first winding wheel, the steering wheel, and the second winding wheel in sequence after passing out of the wire take-up assembly. This helps to guide the pulling wire, change the direction, evenly distribute the force, and provide smooth movement, which can improve the performance of the fitness equipment and the user experience. They can play an important role in different fitness equipment and training movements.

[0020] Further, the control end includes a knob with a display function. By using an existing mature product and combining the display and the operation knob together, the volume can be significantly saved, the aesthetic degree can be improved, and the operation is convenient.

[0021] Further, the control end includes a charging board, and a charging data port and an indicator light exposed outside the housing are provided on the charging board. It can conveniently charge the battery and can also be connected to devices such as a computer for data communication.

[0022] Further, the housing includes an upper cover, a bottom cover detachably connected to the bottom of the upper cover, a fence provided at the middle top of the upper cover, and a top cover detachably provided on the top of the fence. A hole for part of the control end to be exposed is provided on the top cover. In this way, the assembly of the housing can be facilitated, and the maintainability of the power station is improved.

[0023] Further, one end of the bottom of the bottom cover is provided with a pulley. In this way, the end with the pulley can be placed downward and the other end can be lifted, and the power station can be moved through the pulley, which is convenient for movement. Description of the Drawings

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0032] Those skilled in the art should understand that in the disclosure of the present application, the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present application.

[0033] As Figure 1-3 shown, the dual digital magnetic powder damper power station of the present application includes:

[0034] A frame 1, the outer surface of which is covered with a housing 2, and wire outlet ports 211 are provided at both ends in the length direction of the housing 2, and a convex cavity is provided in the middle part, and the convex cavity is used to install the damping structure 3 and the control end 5;

[0035] Among them, pedal areas are provided at both ends of the housing 2 in the length direction. Trademark patterns and anti-slip lines can be set on the pedal areas. The housing 2 includes an upper cover 21, a bottom cover 22 detachably connected to the bottom of the upper cover 21, a fence 23 provided at the middle top of the upper cover 21, and a top cover 24 detachably provided on the top of the fence 23. A hole for part of the control end 5 to be exposed is provided on the top cover 24; the housing 2 here can be injection molded or made of multiple aluminum alloy material plates, and are fixedly connected to each other by means such as snap connections, plug connections, and screws.

[0036] Preferably, a pulley 25 is provided at one end of the bottom of the bottom cover 22. In this way, the end with the pulley 25 can be placed downward and the other end can be lifted, and the power station can be moved through the pulley 25, which is convenient for movement.

[0037] The damping structure 3 includes a magnetic powder brake 31 for providing resistance and a wire winding assembly 32 drivingly connected to the magnetic powder brake 31. The magnetic powder brake 31 and the wire winding assembly 32 are a pair, and two pairs are symmetrically arranged to form the damping structure 3; a wire winding groove 3211 is provided on each wire winding assembly 32, and each wire winding assembly 32 provides a wire winding force through a built-in coil spring 322;

[0038] In this embodiment, as Figure 3-6 shown, a driven wheel 327 is provided on the wire winding assembly 32, a driving wheel 311 is provided on the magnetic powder brake 31, and the driven wheel 327 and the driving wheel 311 are drivingly connected by a belt or a chain. Each wire winding assembly 32 includes a wire winding body 321 provided with a wire winding groove 3211, a coil spring 322 provided in the installation groove of the wire winding groove 3211, a front cover 323 for closing the wire winding groove 3211, and a one-way bearing 324 partially provided in the inner ring of the wire winding body 321. The two wire winding assemblies 32 are both connected to the same main shaft 325. Both ends of the main shaft 325 pass through the two wire winding assemblies 32 respectively and are coaxially rotatably connected to each coil spring 322 through a fixed bushing 326. Each driven wheel 327 is connected to the main shaft 325 through a one-way bearing 324. The presence of the coil spring 322 enables it to automatically wind the cord back into the wire winding groove 3211 when the pull wire 4 is released, thus realizing an automatic wire winding process. The use of the one-way bearing 324 allows the driven wheel 327 to be connected to the main shaft 325, but only allows one-way rotation. Therefore, when the pull wire 4 is released, the coil spring 322 will only drive the main shaft 325 and the wire winding body 321 to rotate, but will not drive the driven wheel 327 to rotate. That is, the user can freely stretch the pull wire 4. When the user relaxes, the one-way bearing 324 will prevent the driven wheel 327 from rotating, so that the wire winding cannot be completed due to the damping of the magnetic powder brake 31.

[0039] Specifically, there are not only one-way bearing 324 (one-way needle bearing) between the main shaft 325 and the driven wheel 327, but also multiple other bearings. A first bushing 3271 is provided inside the inner ring of the driven wheel 327. The first bushing 3271 is integrally injection-molded with the driven wheel 327, and a square frame is provided on the driven wheel 327 to prevent rotation failure. A first deep groove ball bearing 3272 is installed inside the bushing. The first deep groove ball bearing 3272 has the effect that even if the main shaft bears the high-load tension of the driven wheel 327, the wire winding smoothness will not be affected. The one-way bearing 324 is also installed inside the first bushing 3271. A second bushing 3213 is further provided inside the inner ring of the winding body 321. There are two second deep groove ball bearings 3214 between the inner ring of the second bushing 3213 and the main shaft 325, and the one-way bearing 324 is provided between the outer ring of the second bushing 3213 and the inner ring of the first bushing 3271. Among them, the structure of the second bushing 3213 is basically the same as that of the first bushing 3271, and it is also integrally injection-molded with the winding body 321, and a square frame is provided on the winding body 321 to prevent rotation failure. The two second deep groove ball bearings 3214 can evenly distribute the conduction of the large pulling force of the wire 4, so that the rotation is smooth and not affected after release.

[0040] In this embodiment, the magnetic powder controller 31 can be a multi-purpose digital resistance device and its application disclosed in CN114307038A. The magnetic powder controller 31 is smaller in length and volume relative to the motor, which is more conducive to reducing the volume of the strength equipment. Therefore, it is very suitable as the brake of this application.

[0041] The pull handle 8 is respectively connected to each wire winding assembly 32 through the wire 4 and the wire winding wheel set 33. The wire 4 passes through the wire outlet port 211 and is connected to the pull handle 8.

[0042] In this embodiment, each wire winding wheel set 33 includes a first wire winding wheel 331, a steering wheel 332 and a second wire winding wheel 333. The wire 4 passes through the wire winding assembly 32 and sequentially passes through the first wire winding wheel 331, the steering wheel 332 and the second wire winding wheel 333. It helps to guide the wire 4, change the direction, evenly distribute the force and provide smooth movement, which can improve the performance of the fitness equipment and the user experience. They can play an important role in different fitness equipment and training actions.

[0043] Among them, the steering wheel 332 turns the wire rope 4 horizontally by 90°, and the second wire winding wheel 333 turns the wire rope 4 vertically by 90°. The purpose is to enable the wire rope 4 to be tensioned while also being able to turn, providing a smooth stretching experience. Preferably, each wire winding wheel set 33 further includes a guide wheel set 334, and each guide wheel set 334 includes two symmetrically arranged guide wheels, so that the wire rope 4 can pass through the guiding gap between the two guide wheels. The main purpose is to ensure that the wire rope 4 always stays on the correct path, while reducing the possibility of the wire rope 4 being stuck or jammed, ensuring that the user can train smoothly.

[0044] The control end 5 is communicatively connected to the damping structure 3;

[0045] In this embodiment, the control end 5 includes a knob 51 with a display function and a charging board 52. The charging board 52 is provided with a charging data port and an indicator light exposed outside the housing 2. It can conveniently charge the battery 7 and can also be connected to devices such as a computer for data communication. Among them, the knob 51 and the charging board 52 are both prior arts, and the structures and principles are not described herein again. Here, the charging data port is preferably a type-c.

[0046] The rotation speed sensor 6 is communicatively connected to the control end 5, is arranged on one side of the wire winding assembly 32, and is used to detect the rotation speed of the wire winding assembly 32.

[0047] In this embodiment, the rotation speed sensor 6 includes a magnet 61 arranged on the wire winding body 321 and a magnetic inductor 62 (also called a Hall sensor) installed on the inner wall of the housing 2. The magnetic inductor 62 can detect the magnetic field change when the magnet 61 passes by, causing the movement of charges in the magnetic inductor 62, and the movement of these charges will generate an electric current signal. The frequency of this signal is proportional to the rotation speed of the wire winding body 321. By measuring the frequency of this electric current signal, the rotation speed of the wire winding body 321 can be calculated, and then converted into digital data such as speed and distance. After a series of conversions like this, training parameters such as the user's output speed can be calculated (the specific conversion is a prior art and not the protected technical point of this application).

[0048] Preferably, the front cover 323 is provided with a plurality of grooves for installing the magnet 61, and the magnets 61 are evenly spaced along the circumferential direction of the front cover 323. Of course, the magnet 61 can also be pasted on the front cover 323 or fixed to the front cover 323 with screws, and this is not limited here.

[0049] The battery 7 is arranged in the convex cavity, and the battery 7 is electrically connected to the control end 5. In this way, it is not necessary to be restricted by the length of the wire and the position of the socket, greatly improving the usage flexibility of this strength station and enabling it to be used in more occasions.

[0050] The parts not detailed in this application are prior arts, so this application does not elaborate on them.

[0051] It will be understood that the term "a" should be construed as "at least one" or "one or more". That is, in one embodiment, the number of an element may be one, while in other embodiments, the number of the element may be multiple. The term "a" should not be construed as a limitation on the quantity.
