Technical Field

The invention relates to the technical field of resistance control, in particular to a resistance adjusting device and a resistance adjusting method for controlling resistance by controlling the movement of a sliding block 1 through the change of a connecting rod.

Background

The function of resistance adjustment is widely applied to devices (such as traditional exercise bicycles, VR bicycles and the like) for simulating riding, wherein the function of magnetic control resistance adjustment is applied mostly, and mainly, when a user uses the riding device, the resistance generated by friction between wheels and the ground in a real environment is simulated by controlling the resistance generated by a magnetic control module (for example, controlling the distance between a rotating wheel and a magnet) of the riding device, so that the user can obtain an experience similar to riding on a real road surface under the condition that the riding device does not move, and the riding device can generally perform visual simulation by combining a virtual picture displayed by a front screen, so as to obtain a better riding experience. However, the conventional magnetic control resistance device cannot simulate the effect of real-time resistance change of the riding device on an uphill slope or a downhill slope (the magnetic force is controlled by controlling the distance through a common motor, the stress change response time is very delayed, the running sound is relatively loud and the cost is high even though the magnetic control resistance device is driven by a high-end motor), so that a user cannot sense the change of real resistance when pedaling in real time when riding on the uphill slope or the downhill slope is simulated, and the reality of the immersive experience of the simulated riding is greatly influenced.

The rotating wheel 3 calculates the number of turns of the rotating wheel in unit time through a speed encoder.

The resistance frame 2 is rotatably connected with the telescopic rod 10 of the electric cylinder 25 (connected through the rotating shaft 27), the electric cylinder 25 is driven by the motor 12, the motor 12 is arranged on the electric cylinder 25, the electric cylinder 25 is rotatably connected with the bottom plate 20 (connected through the rotating shaft 27), the bottom plate 20 is connected with the rotator 24, and the bottom plate 20 can be driven to rotate by the rotator 24.

The slider 1 is made of a magnetic substance, the magnetic substance is a substance capable of generating magnetic force, such as a permanent magnet, or contains a permanent magnet, and the rotating wheel 3 is made of a material (such as an iron material) capable of being magnetically attracted by the permanent magnet. The setting the second link 6 is parallel with perpendicular 5, the contained angle of straight line 30 and perpendicular 5 is alpha, straight line 30 is the straight line through two points on slider 1, perpendicular 5 is the straight line perpendicular with water flat line (or horizontal plane), also is the straight line parallel with the direction of gravity.

If the straight line 30 is parallel to the resistance frame 2 (for example, a straight plate), the included angle α has a value equal to the rotation value of the resistance frame 2, and is simulated in an uphill state (for example, fig. 3) when 90 ° > α > 0 °, and is simulated in a downhill state (for example, fig. 2) when 180 ° > α > 90 °; now, if the maximum horizontal inclination simulating an uphill slope is set to 20 degrees, then α =70 °, and if the maximum horizontal inclination simulating a downhill slope is set to 20 degrees, then α =110 °, then, when the resistance frame 2 is inclined 20 ° downhill (i.e., α =110 °), the distance between the slider 1 and the wheel 3 is L2 (i.e., the distance between the slider 1 and the point a on the wheel 3), and the magnetic force experienced by the wheel 3 is the minimum (i.e., the rotation resistance experienced by the wheel 3 is the minimum); when the resistance frame 2 is inclined by 20 ° on an uphill slope (i.e. α =70 °), the distance between the slider 1 and the runner 3 is L1 (i.e. the distance between the slider 1 and the point a on the runner 3), and the magnetic force applied to the runner 3 is the largest (the rotation resistance applied to the runner 3 is the largest); similarly, when the straight line 30 (or the resistance frame 2) is perpendicular to the perpendicular line 5, the distance between the slider 1 and the first wheel 8 is L3 (i.e. the distance between the slider 1 and the point a on the wheel 3), and the magnetic force applied to the wheel 3 is smaller than the magnetic force applied to the wheel during uphill slope but larger than the magnetic force applied to the wheel during downhill slope (i.e. the wheel simulates driving on a horizontal ground, and the wheel has larger resistance than the wheel during downhill slope but smaller resistance than the wheel during uphill slope); the L1, the L2 and the L3 meet the requirements that L2 is more than L3 is more than L1.
