Fig. 8 is a schematic diagram showing the functions of the individual exercise machine mode according to an embodiment of the present invention (individual exercise machine training mode 3). As shown in fig. 8, the single exercise machine training mode 3 is a mode in which both ends of the long straight bar 4 are connected to 2 lower power sources 12 on the left and right sides of the exercise machine main body 1, and the user stands on the exercise machine main body 1 while holding the long straight bar 4 with both hands to perform upper limb strength training.

Of course, the above description is only three specific strength training modes of the single body builder, and the multifunctional body builder of the present invention can also realize various strength training modes, which are not listed here.

Next, an example of the dynamic control of the output resistance of the multi-functional health machine according to an embodiment of the present invention will be described with reference to fig. 4, 9 to 10B.

As shown in fig. 4, the long straight bar 4 for rowing training is butted with an upper power source 11 and a lower power source 12 through 4 pull ropes extending from the body builder body 1, a person sits on a sliding seat, feet are fixed on pedals, and the long straight bar 4 is pulled by both hands to perform rowing actions similar to kayaking motions. The body-building machine body 1 monitors the lengths of the two pull ropes of the upper power generation source 11 and the two pull ropes of the lower power generation source 12 in real time, and can obtain the approximate position of one end of the long straight rod 4 and the angle of the pull rope of the lower power generation source 12 connected with the end through three-dimensional space conversion, so as to be used as the basis for calculating the current output resistance. As shown in fig. 10, an angle sensor 41 may be provided on the long straight rod 4 to detect a rotation angle of the long straight rod 4 about its axis, and thereby a water-holding angle of the paddle in water is obtained, and the output resistance is calculated from the water-holding angle.

Specifically, fig. 9 is a schematic diagram for explaining the dynamic resistance control by the calculated angle in one embodiment of the present invention. As shown in fig. 9, the kayak mode requires the use of 4 pull cords to connect the lower and upper power sources 11, 12. Here, the positions of the upper and lower power sources 11 and 12 refer to the front end positions of the upper swing arm and the lower swing arm of the exercise machine body 1. Since the positions of the upper and lower power sources 11, 12 are fixed, the length of a fixed side b (for example, 1034.4mm) of the triangle ABC can be obtained, and the lengths of the pulling ropes a and c connected to one end of the long straight bar 4 from the upper and lower power sources 11, 12 can be detected in real time by the position sensor of the exercise machine body 1, and thus the lengths of the pulling ropes a, c are also known. Knowing the lengths of the three sides a, b, c of triangle ABC, the trigonometric function formula is applied: cosC ═ a ² +b ² -c ² ) And (2ab), a real-time angle value of the angle C (the included angle between the side a and the side b) at one end of the long straight rod 4 can be obtained.

As also shown in fig. 9, the plane of the guide rail is defined as the horizontal plane in the simulation reality, and when the rowing machine 2 is used, the stage when the oar enters the water is defined when one end of the long straight bar 4 in the hand is lower than the plane of the guide rail. When the angle of C gradually increases and exceeds the plane of the guide rail, the water starts to enter, and the critical value of the stay cord a and the plane of the guide rail is 135 degrees at the nearest end and 132 degrees at the farthest end according to the actual product design parameters.

In the present embodiment, the force source can dynamically provide different resistance based on the angle C of the end of the long straight bar 4 detected in real time, the angle of the above-mentioned entry threshold value, and the information of the resistance of the paddle in different positions and the water-catching angle in the water, which is stored in the microcomputer of the fitness equipment main body 1 and is obtained in advance, so as to simulate the resistance change during the real rowing exercise. For example, when the C is larger than 145 degrees, the resistance provided by the motor is not increased due to the increase of the C, but different resistances are provided according to the different states of the long straight rod simulating the paddle blade in the water according to the rotating angle of the long straight rod. In reality, two ends of a paddle are provided with the paddles, when the paddles are completely vertical to water flow, the resistance of the water flow to the paddles is maximum, the output of athletes is maximum, the forward power of the kayak is maximum, and the power generation source needs to provide the maximum resistance; and when the blades are not vertical to the water flow and gradually change from 90 degrees to 0 degree, the resistance of the power generation source is gradually smaller. The angle sensor 41 of the present invention is provided for simulating the blade changing process.

Fig. 10A and 10B are schematic views of an angle sensor according to an embodiment of the present invention.

As shown in fig. 10A, the long straight rod 4 is provided at both ends thereof with connectors 40 rotatable with respect to the long straight rod 4 (only 1 connector 40 provided at one end of the long straight rod 4 is shown in fig. 10), the pulling rope a and the pulling rope c are butted against the long straight rod 4 via the connectors 40, and an angle sensor 41 capable of detecting a relative rotation angle between the long straight rod 4 and the connectors 40 is provided on the connectors 40 (in fig. 10A, P1 indicates that the angle sensor 41 is in the first position, and P2 indicates that the angle sensor 41 is in the second position), whereby the water holding angle of the paddle in water is obtained. Specifically, when C <135 °, the paddle is not in water, the angle sensor 41 does not function, and when C >135 °, the paddle starts to enter water, defining that the arm wrist, the two-end connector and the pull rope are substantially in the same straight line (as shown in fig. 10B), at this time, the read value of the angle sensor is 90 °, and the motion direction of the paddle is consistent with the water catching angle, and the output resistance is maximum; in the dynamic movement process, the angle between the wrist of the arm and the connecting pieces at the two ends can change along with the change of the movement posture, the angle sensor reads different values, and the output resistance is correspondingly adjusted.

As described above, the utility model discloses a multi-functional fitness equipment is when the fitness equipment main part with rowing machine combination, not only can realize multiple rowing training function, can also utilize the resistance control mechanism of fitness equipment main part to provide different resistance dynamically, comes the resistance change of simulation oar blade when being in different states in real aquatic.
