Description

High-torque magnetic resistance braking device

The present invention relates to a fitness exercise equipment device, especially a high-torque reluctance brake device in which a control circuit inputs a moderate current according to a set torque, so that a reluctance mechanism with a specific angle and its coupled rotating flywheel produce reverse resistance .

By the way, many fitness sports equipment will be equipped with flywheels to increase the inertial force of rotation and can be used as a load to adjust the load; Figure 1A shows the US No. 5,711,404 "MAGNETIC ADJUSTABLE" (MAGNETIC ADJUSTABLE) LOADING DEVICE WITH EDDY CURRENT), the device includes: a rotor composed of a flywheel 710 and a metal conductor 720; the inner edge of which is equipped with a stator 750 composed of a conductive magnet piece 751 and a permanent magnet 752, through the adjustment device 771 The free end of the traction magnet piece 751 is displaced, thereby changing the gap d1 between the rotor 710, 720 and the stator 750, causing the magnetic flux density to change, so as to achieve the effect of stepless and continuous adjustment of the load resistance; however, the adjustment device 771 adjusts the load resistance through manual operation. The function of automatically adjusting the load cannot be achieved, so this patent has a lack of automation.

In addition, in recent years, fitness sports equipment often uses flywheels to install permanent magnets, and then use armatures as stators to make stator coils generate current, which is the power required to control and brake the load; Figure 1B shows the US No. 6,084,325 "Power Generation and "BRAKE DEVICE WITH A COMBINATION OF POWER-GENERATING AND EDDY-CURRENT MAGNETIC ESISTANCE", the device includes: the rotating wheel of sports equipment drives the flywheel 820 to rotate, and the flywheel 820 sticks the permanent magnet 821 and the stator core. 830 forms a magnetic circuit, which makes the coil 831 generate current; the current is rectified and filtered into direct current, which supplies the control instrument and the brake core 850, so that the brake core 850 forms an eddy current (EDDY CURR-ENT), which in turn causes the flywheel 820 A magnetoresistive effect; press, this structure can achieve Excellent exercise effect. However, the output power of the generator is closely related to the rotation speed. Because the rotation speed of the generator is limited by the magnetic resistance, it has not exerted its due efficiency. Moreover, the mechanism is more complicated and the manufacturing cost is relatively high. Because of its high height, it is not suitable for installation on small-sized or less-controlled sports equipment.

Press again, the adjustment load in Figure 1A lacks automation, and the mechanism in Figure 1B is not suitable for small and low-cost sports equipment; therefore, how to integrate the advantages of the two can simplify the mechanism, reduce the size, and reduce the manufacturing cost, and The ability to reduce the kinetic energy load to supply small sports equipment has become the goal of the creator's creative research and development.

The reason is that the main purpose of the present invention is to provide an eddy current reluctance braking device that can be applied to small fitness sports equipment and can automatically adjust the reluctance load.

The secondary objective of the present invention is to provide a high-torque reluctance brake device which can simplify the mechanism and reduce the manufacturing cost while improving the load efficiency.

Some details may not be completely drawn in order to keep the drawings concise.

First of all, please refer to FIG. 2 which shows the structure of the "high torque magnetic resistance braking device" 100 of the present invention, which includes: a support frame 10 assembled from inner and outer plate bodies 11, 12, each of the upper ends A shaft hole 13 is provided. The shaft hole 13 is provided with a plurality of positioning holes 14 at equal intervals around the shaft hole 13, and a foot 15 is provided at the lower ends of the inner and outer plate bodies 11 and 12 respectively. The support is made by bolt locking the slot hole 16 The frame 10 is fixed on the frame body of fitness sports equipment; a plurality of positioning rods 17, each with a nut to lock the positioning rod 17 in the positioning hole 14, so that the inner and outer plates 11, 12 are combined into one body; An outer rotor 20 includes a flywheel 21 and a magnetic permeable ring 22; the flywheel 21 provides an inertially rotating disk, with an outer ring 211 and an inner side wall 212, and the center of the inner side wall 212 A hub 214 with a shaft hole 213 is formed; a rotating shaft 30 penetrates the shaft hole 213, And a key block 215 is embedded in the middle part to make the rotating shaft 30 and the flywheel 21 rotate synchronously; a transmission wheel 40 is sleeved on one end of the rotating shaft 30 with a one-way bearing 31 for one-way fitness For the power transmitted by sports equipment, in the present invention, the transmission wheel 40 is a belt pulley; the rotation shaft 30 is located on both sides of the hub 214 of the flywheel 21, and a ball bearing 32 is set on each, and a ball bearing 32 is set on the outer circumference of the ball bearing 32. The bearing seat 33, and the bearing seats 33 on the front and rear sides are respectively locked in the shaft holes 13 of the inner and outer plates 11 and 12 respectively.

In addition, at least two reluctance mechanisms 50 each include a brake core 51, an electromagnetic coil 52, an input wire 53 connected to the electromagnetic coil, and a front and rear brackets 54, 55. The brake core 51 is provided with a A mountain-shaped recessed accommodating part is used to cover the electromagnetic coil 52; the front and rear brackets 54, 55 are placed on the front and rear sides of the brake core 51, and bolts penetrate into the brake core 51. Through holes, the front and rear brackets 54 and 55 are locked at the positioning holes 14 of the inner and outer plates 11 and 12; in the present invention, in order to avoid the magnetic force lines of the brake cores 51 of the two reluctance mechanisms 50 from interfering with each other , And make the eddy current magnetic resistance reach the highest torque. When the two magnetic resistance mechanisms 50 are assembled at the outer periphery of the magnetic permeable ring 22, the mutual angle θ must be set to be greater than 30 and less than 180 degrees; at the same time, To produce a magnetic resistance effect, the outer edge of the brake core 51 installed in the front and rear brackets 54, 55 needs to form a magnetic field gap G with the outer peripheral surface of the magnetic permeable ring; the first embodiment of the present invention is The included angle θ of the two reluctance mechanisms 50 is set to be greater than 30 and less than 90 degrees, as shown in Figures 3-6; the second embodiment is to set the included angle θ of the two reluctance mechanisms 50 to be greater than 90 and less than 180 degrees, such as As shown in Figures 10-11; the included angle θ is set to a limit greater than 30 degrees, not only to avoid the interference of the magnetic lines of the brake cores 51 of the two reluctance mechanisms 50, but also to produce the same torque. The two magnetoresistive mechanisms 50 can disperse the magnetoresistive effect on two parts of the outer circumference of the magnetic permeable ring 22. Compared with the one magnetoresistive mechanism 50, the magnetoresistive effect can be concentrated on one part of the outer circumference of the magnetic permeable ring 22. The rotation of the rotor 20 produces a smaller yaw and thus increases its service life.

Figure 7 shows the structure of the outer rotor 20 in the present invention; the outer rotor 20 includes a flywheel 21 and a magnetically permeable ring 22; the flywheel 21 has an outer ring body 211 and an inner side wall 212, and A hub 214 with a shaft hole 213 is formed at the center of the inner side wall 212; the shaft hole 213 is provided with a key groove 216, which acts as a shaft The hole 213 is sleeved on the rotating shaft 30, and a key block 215 is embedded in the key groove 216 to make the rotating shaft 30 rotate synchronously with the flywheel 21; the magnetic permeable ring 22 is made of a material with high magnetic flux density In the present invention, the magnetic permeable ring 22 is made of carbon steel with a carbon content of 0.15 to 0.25%; furthermore, the permeable ring 22 is sleeved on the flywheel 21 made of cast iron in a tightly fitting manner. The outer periphery of the outer ring body 211, or the magnetic permeable ring 22 is directly formed on the outer periphery of the outer ring body 211, which achieves the function of creating a closed magnetic circuit with the electromagnetic coil 52 through the magnetic permeability of its own material ; In the present invention, the main purpose of setting the magnetic permeable ring 22 on the periphery of the outer ring body 211 of the flywheel 21 is to increase the magnetic flux density of the outer rotor 20 and to make it compared with the brake core 51 of the reluctance mechanism 50 The large eddy current magnetic resistance does not increase the material cost too much; however, the selection of the material of the magnetic permeable ring 22 and the manner in which the magnetic permeable ring 22 sets the periphery of the flywheel 21 are not limited to this.

Please further refer to FIG. 8, which is the structure configuration state of the first embodiment of the present invention, including a control circuit unit 60, which is assembled on the side of the support frame 10 in a built-in form, and it includes at least a microprocessor The device 61, a DC control circuit 62, an input device 63 for inputting the desired torque setting value, and a transmission port 64 for loading the resistance curve graph; The transmission mechanism A connects the transmission wheel 40 (pulley) to rotate the outer rotor 20. When the user inputs the desired torque value of the motion from the input device 63, and selects the desired resistance curve from the transmission port 64, the microprocessor 61 refers to the trajectory of the resistance curve and the torque setting value, and then sends the correct value. The control signal is sent to the DC control circuit 62 to generate a moderate current and input it into the input line 53 of the two reluctance mechanisms 50 simultaneously. Then the current of the electromagnetic coil 52 will generate a magnetic field on the brake core 51 through the principle of magnetoelectric conversion. , A closed magnetic circuit is formed between this magnetic field and the coupled rotating magnetic ring 22; since the outer rotor 20 is in a rotating state, this closed magnetic circuit will be destroyed. According to Lenz’s law, when a stable When the magnetic circuit is damaged by an external force, a force of the same magnitude and opposite direction will be generated to resist. This force will form the required resistance on the fitness equipment, and the microprocessor 61 will continue to refer to its torque setting conditions through this force. The DC control circuit 62 adjusts the current of the electromagnetic coil 52 so that the resistance value is equivalent to the The setting value entered by the user can then achieve the effect of the desired exercise load.

Figure 9 shows a schematic diagram of the resistance curve of the movement. The resistance curve has many different levels of difficulty. However, the resistance is basically set to the initial stage, the gradual increase stage, and the torque control stage; when the initial stage is input When the current is constant, the input current will linearly increase the resistance during the gradual increase phase, while the input current will be automatically adjusted according to the torque setting conditions during the torque control phase; press, the resistance curve of the resistance curve will allow users to obtain different levels of resistance. The sense of stability can not only improve comfort but also avoid sports injuries caused by sudden changes in resistance; therefore, the present invention can allow users to select the desired resistance curve through the transmission port, thereby increasing the variability of exercise.

According to the present invention, the outer rotor 20 is driven by the transmission wheel 40 to rotate. It has a flywheel 21 that provides inertial rotation and a magnetic ring 22 with high magnetic flux density; the magnetic resistance mechanism 50 is set on the guide wheel. At the outer periphery of the magnetic ring 22, it has a brake iron core 51 and an electromagnetic coil 52, and the outer edge of the brake iron core 51 and the magnetic ring 22 have a magnetic field gap G, thereby generating a magnetic resistance effect; the present invention An input device 63 is provided for inputting the desired torque value, and the DC control circuit 62 will generate an appropriate current according to which it is input to the electromagnetic coil 52 to form the required movement resistance; because the invention does not provide power generation The required stator coil and AC-DC conversion components can simplify the mechanism, reduce the volume, and reduce the manufacturing cost, and make it applicable to small fitness sports equipment. At the same time, the present invention is based on the current applied to the electromagnetic coil 52 The size is used to control the magnetoresistive load. Since the mechanism is a non-contact resistance device, the present invention also has the advantages of easy resistance control, no wear of components, and low maintenance cost.

Secondly, the outer rotor 20 of the present invention includes a flywheel 21 for inertial rotation and a magnetic ring 22 with high magnetic flux density. The magnetic ring 22 is tightly sleeved on the periphery of the flywheel 21, and the outer The rotor 20 will be driven by the transmission wheel 40 to rotate; the two magnetic resistance mechanisms 50 are arranged at the outer periphery of the magnetic ring 22, and the outer edge of the brake core 51 and the magnetic ring 22 have a magnetic field gap G; A moderately large current is input to the electromagnetic coil 52 of the reluctance mechanism 50, and the current will generate a magnetic field on the brake core 51, and according to Lenz’s law, this magnetic field will be formed between the coupled rotating magnetic ring 22 A counter resistance Since the magnetic permeable ring 22 has a high magnetic flux density, and the two magnetic resistance mechanisms 50 form an angle θ greater than 30 and less than 180 degrees between each other, the magnetic lines of force of the brake core 51 will not interfere with each other, and the eddy current magnetic resistance will reach the highest Torque, so the present invention can achieve the effect of high-efficiency sports loads.

Press again, the present invention is provided with an input device 63 and a transmission port 64, which can be used to input the desired torque setting value and load the software of the resistance curve; when the user inputs the torque condition, the micro-processing of the control circuit unit 60 The device 61 refers to the trajectory of the resistance curve and the torque setting value, and then generates a moderate current to the electromagnetic coil 52 of the reluctance mechanism 50, and the brake core 51 will generate between the magnetic ring 22 of the coupling rotation An eddy current magnetic resistance forms a reverse resistance to the outer rotor 20. Since the graphic of the resistance curve allows the user to get a sense of the smoothness of the resistance at different levels of difficulty, it can not only improve the comfort but also avoid the injury caused by the sudden resistance change; therefore, the present invention can allow the user to use the transmission port 64 Choose the desired resistance curve to increase the variability and comfort of the exercise.
