Fitness equipment sensing device

This creative department is related to fitness equipment, especially a sensing device that calculates the motion stroke.

Modern people are busy and stressed, and it is easy to cause the circulation of the human body to decline, the spirit is not good, and increase the chance of disease. As people's health awareness increases, the use of fitness equipment to increase the amount of exercise to exercise their body and increase lung capacity, in order to maintain the body and mind in a better state has gradually become a national movement.

In order to let the user know how much exercise each time the fitness equipment is used, and to judge or calculate whether the current amount of exercise is sufficient to meet the needs of the human body to help metabolism, the manufacturer has installed a sensing device on the fitness equipment to measure the use. The movement of the time is converted into data for the user's reference.

For the fitness equipment that allows the user to perform the swinging motion, the structure that provides the user's operation is usually connected indirectly to the wheel body. When the user completes the periodic motion, the wheel body will also rotate relatively one turn. In general, the inductive device is mounted on the wheel body, and the number of rotations of the wheel body is measured as a reference for the exercise amount data.

However, for elderly and frail elderly people or those who are physically weak due to illness or other reasons, the use of the body often fails to effectively drive the body movements. Unable to complete the cycle movement, the wheel body on the fitness equipment will not rotate relatively one turn, which will greatly affect the authenticity of the exercise data. To this end, if a product improves the foregoing, it will not only provide consumers with purchasing options, but also meet market demand.

In view of this, the purpose of the present invention is to provide a sensing device for a fitness device, which has the characteristics of accurately measuring the movement stroke of the user.

In order to achieve the above object, the present invention provides a sensing device for a fitness device, the fitness device includes a base frame and a connecting rod; the connecting rod is pivotally connected to the base frame and is pivoted relative to the base frame by force; The sensing device includes a sensed component and a sensing unit; the sensed component is coupled to the link and is driven by the link to move along a path; the sensing component includes a plurality of sensors disposed thereon On the pedestal, when the sensed component is in the sensing range of each of the inductors, each of the inductors is driven to output a signal; wherein when the sensed component moves along the path, the sensed component passes sequentially The sensing ranges of the sensors enable the sensors to separately transmit the signal.

The effect of this creation is to accurately measure the user's movement stroke.

In order to explain the present invention more clearly, a preferred embodiment will be described in detail with reference to the drawings. Figure 1 shows an exercise device incorporating the sensing device of a preferred embodiment of the present invention. The exercise equipment includes a base frame 10 and a wheel body 20.

The base frame 10 includes a bottom rod 11 and two cross bars 12 and 13 respectively connected to the two ends of the bottom rod 11. The bracket 14 is arched and has one end fixed to the bottom rod 11 and the other end fixed to the cross rod 12. A column 15 is located between the bracket 14 and the bottom rod 11, and the bracket 14 and the bottom rod 11 are connected at both ends. The bracket 14 is provided for a mat (not shown), and the column 15 is rotatably provided for the wheel 20. The other cross bar 13 is provided with two shaft portions 13a.

The fitness equipment of the embodiment further includes two connecting rods respectively disposed on two sides of the wheel body 20. Each of the links includes a V-shaped rod 30 and a driven rod 32, respectively. The V-shaped rod 30 is pivoted at a bottom portion to a corresponding shaft portion 13a. A free end of the V-shaped rod 30 is connected to a pedal (not shown), and the other free end is pivotally connected to one end of the driven rod 32. The other end of the follower rod 32 is eccentrically pivotally connected to a turntable 34 disposed coaxially with the wheel body 20, so that the follower rod 32 rotates with the wheel body 20. Do an elliptical trajectory. The combination of the foregoing components allows the user to sit on the seat cushion and pedal the pedals with the two feet alternately, so that the V-shaped bar 30 pivots back and forth with respect to the base frame 10 due to the force, and pulls the follower bar 32 to interlock the wheel body. 20 turns to achieve the purpose of leg movement.

The fitness equipment of the embodiment further includes a sensing device, and the sensing device includes a sensing component 40 and a sensing unit 42. The sensing member 40 is coupled to the inner side of the driven rod 32 of one of the links, and includes a magnet, and the sensing member 40 is rotated in an elliptical path as the user moves. As shown in FIG. 3, the sensing unit 42 includes a circuit board 421, a processor 422 and a plurality of sensors 423. The circuit board 421 is mounted on the bracket 14 and faces the sensed component 40, the processor 422 and the sensor. The 423 is disposed on the circuit board 421 and electrically connected to the circuit board 421. In this embodiment, the sensor 423 is a Hall sensor, and the sensors 423 are located within an elliptical trajectory of the sensing component 40 and The alignment is in a straight line, wherein the straight line passes through the long axis of the elliptical path.

As shown in FIG. 4, when the user sits on the seat cushion and continuously pedals the pedals with both feet for continuous motion, the wheel body 20 rotates smoothly, and the sensing member 40 follows an elliptical path, and the sensors are rotated. The device 423 sequentially senses the sensed components 40 and outputs a signal to the processor 422. The processor 422 further determines the actual moving distance of the sensed component 40 according to the signals. Can be used as a reference for the amount of exercise.

Please cooperate with Figure 5, when the user with weak limbs is used for rehabilitation, the user is also seated on the seat cushion and pedals with the feet to exercise, but the difference is that physical strength or subject to limbs When the action is caused, the user does not normally drive the wheel body 20 to completely rotate one turn, the sensed member 40 still moves along the curved track as the user moves, and sequentially passes through the partial sensor 423. The sensing range is such that the sensors 423 sensed by the sensing component 40 respectively send signals to the processor 422, and the processor 422 can also achieve the effect of determining the actual moving distance of the sensing component 40.

In other words, whether the user can normally drive the wheel body 20 to rotate completely one turn or rotate a half turn, when the sensed component 40 falls within the sensing range of any of the sensors 423, the sensor 423 will be driven to emit The signal, in turn, causes the processor 422 to determine the moving distance of the sensed component 40 according to the signals, so as to accurately measure the actual moving distance.

It is noted that, in order to allow the sensors 423 to be inductively sensed by the sensing member 40 to avoid unsensing, in the embodiment, the inductors 423 are not only arranged along a straight line, but also two of the straight lines. The end points are located on the curved path such that the sensors 423 are positioned close to the arcuate path, so that the driven sensing member 40 can surely fall into the sensing range of the inductor 423.

It should be noted that the manner in which the inductors 423 are arranged on the circuit board 421 is not limited to the above. As shown in FIG. 6, a plurality of sensors 52 on the sensing unit may be staggered and located. Within the range of the elliptical trajectory of the sensing member. Alternatively, as shown in FIG. 7, the inductors 62 are arranged along an arcuate trajectory and are also located within the range of the elliptical trajectory. Alternatively, as shown in FIG. 8, the elements of the sensor 72 are arranged in a straight line with the contents of FIG. 3, but outside the range of the elliptical path of the sensed member 74. The sensed component can be matched with the arrangement of the foregoing three, and the width or length of the sensed component can be appropriately adjusted to achieve the effect of sensing.

The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present application and the scope of the patent application are intended to be included in the scope of the present patent.
