Description

Exercise wheel set with preset resistance parameters

technical field

The utility model relates to sports equipment, in particular to an exercise wheel set which can preset resistance parameters.

Background technique

In the indoor bicycle of traditional sports equipment, its resistance wheel 70 is as shown in Figure 6, mainly by driving a wire puller 72 by a pull wire motor 71, and pulls a magnet through a steel cable 74 with this wire puller 72 (Fig. Not shown), by adjusting the distance between the magnet and the flywheel 76 on the indoor bicycle, the active force that the magnet acts on the flywheel 76 can be adjusted, and then reach the effect of adjusting the resistance acting on the flywheel 76.

However, when the above-mentioned existing resistance wheel 70 controls the resistance, the wire puller 72 is controlled by the wire pull motor 71 to pull the magnet through the wire rope 74, and the precision of production is not easy to control, so the pull wire The minimum pulling force of the device 72 must be adjusted through an adjustable sleeve screw 78 to produce different pulling distances to obtain the lowest torque value, and the motor can be electrically connected to an external electronic control board to control the motor.

Again, the aforementioned existing resistance wheel is for the motor to control the magnet through the steel cable 74. The magnet is installed on the axle frame of the flywheel 76, and the motor is installed on the base of the resistance wheel. 6, it is necessary to adjust the torque, and the adjustment must be carried out by placing the finished product on the adjustment machine, which is a time-consuming and laborious method, and the production efficiency cannot be improved. And this kind of structure can't provide the producer to pre-set the pulling force or the setting of the pulling force parameter in advance, and it must be assembled before setting. In addition, because the steel cable 74 is elastic, and the sleeve screw 78 can only be adjusted at a single point (that is, zero point adjustment), it is almost impossible to adjust the tensile force through the steel cable 74 very accurately. .

Also, even if the correct tension value is adjusted, the relevant values of the tension and angle must be written into the memory of the electronic control board to complete the setting. The electronic control board is actually separated from the entire resistance wheel and is only connected by wires. Therefore, if one of the electronic control board, wire puller, sleeve screw or steel cable is damaged and replaced, the torque setting will not be changed. The complex is correct, so the control of the pulling force will also have inaccurate problems.

As shown in Fig. 1 to Fig. 3, a kind of exercise wheel set 10 that can pre-set the resistance parameter provided by the first preferred embodiment of the present utility model mainly consists of a base 11, a flywheel 21, a damper 31, A motor 41 and a control circuit 51 are formed, wherein:

The base 11 is a pole 12 extending upward, and a fixed plate 14 is arranged on the pole 12 .

The flywheel 21 is disposed on the pole 12 of the base 11 , and in this embodiment, the flywheel 21 is concentric to the center of the fixed disk 14 .

The damper 31 is located on the fixed plate 14, the damper 31 has a displacement mechanism 32 and a magnet group 36 arranged on the displacement mechanism 32, the magnet group 36 is composed of two arc-shaped magnetic plates 37, the One end of the two arc-shaped magnetic plates 37 is rotatably disposed on the fixed disk 14 , and the arc-shaped outer edges of the two arc-shaped magnetic plates 37 correspond to the peripheral edge of the fixed disk 14 . The displacement mechanism 32 has a knob 33 and two connecting rods 34. The knob 33 has an elongated body 331 passing through the fixed disk 14, and a connecting block 332 is formed at the end of the elongated body 331. The knob 33 is directed toward A connecting arm 333 is extended on both sides, and the two connecting rods 34 are respectively connected to the ends of the connecting arms 333 with one ends rotatably, and the other ends of the two connecting rods 34 are respectively connected to the two connecting rods 34 in a rotatable manner. The free end of arc-shaped magnetic plate 37. By turning the knob 33 , the two connecting rods 34 can be linked to drive the two arc-shaped magnetic plates 37 to move closer to/away from the flywheel 21 .

The motor 41 is disposed on the fixed plate 14 and connected to a gear box 44 , and the gear box 44 is connected to the connecting block 332 of the displacement mechanism 32 . Through this, the gear box 44 can be driven by the motor 41 , and then the knob 33 can be driven to swing the two arc-shaped magnetic plates 37 to adjust the positions of the two arc-shaped magnetic plates 37 .

The control circuit 51 mainly includes a processor 52 , an angle sensor 53 and a memory 54 connected to the processor 52 . The control circuit 51 is connected to the motor 41 and the damper 31 for detecting the position of the magnet set 36 and controlling the motor 41 to drive the displacement mechanism 32 to adjust the position of the magnet set 36 .
