Detailed Description
In order to make the invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.
As shown in fig. 1, an active resistance type exercise apparatus disclosed in this embodiment includes a frame 1, a resistance component 2, an operation component 3, a transmission component 4, a man-machine intelligent interaction terminal 5, and a remote APP terminal 6.
The frame 1 is a steel structure for mounting or placing other components. The frame 1 is provided with a seat for a body-building person to sit and exercise and a linear guide rail which is horizontally arranged. The linear guide rail is provided with a sliding block and a rear limiting part A and a front limiting part B which are used for limiting the moving range of the sliding block on the linear guide rail.
The operating member 3 includes a base 33, a foot pedal 31, and a grip 32. The slider is fixed on the base 33 such that the base 33 is freely movable on the linear guide within a range defined by the rear limit member a and the front limit member B. The exerciser applies a force to the operation member 3 through the foot pedal 31 or the grip lever 32, wherein the foot pedal 31 is provided for the exerciser to pedal and the grip lever 32 is provided for the exerciser to grip.
The resistance member 2 is a device for outputting rotation and torque, and is fixedly mounted on the frame 1. In the present embodiment, the resistance member 2 includes a motor 21, a speed reducer 22, and a controller 23. The motor 21 is controlled by a controller 23, and an output end of the motor 21 is connected with a speed reducer 22.
The transmission part 4 can adopt a chain wheel and chain structure or a synchronous pulley structure. In this embodiment, the transmission member 4 adopts a sprocket-chain structure including a driving sprocket 41, a chain 42, and a driven sprocket 41'. The output end of the speed reducer 22 is connected to the rotation shaft of the drive sprocket 41, one end of the chain 42 is connected to the base 33, and then sequentially passes around the drive sprocket 41 and the driven sprocket 41', and the other end is connected back to the base 33.
The motor 21 generates a resistive torque in a resistive mode under the control of the controller 23 to form a resistance, or generates a driving torque in a resistive mode to form a driving force. The resistance or driving force is transmitted to the operating member 3 through the chain 42, and at the same time, the force applied to the operating member 3 by the exerciser is also transmitted back to the resistance member 2 through the chain 42, and the resistance moment or driving moment outputted from the motor 21 is adaptively adjusted by the resistance member 2 according to the received force. In this embodiment, the specific structure and method for implementing adaptive adjustment are as follows:
The rotational speed of the drive sprocket 41 is detected in real time by an encoder. In the resistance mode, the force applied by the exerciser on the operating member 3 is transmitted to the drive sprocket 41 through the chain 42, so that the drive sprocket 42 rotates in one direction at the rotation speed V1. At this time, the motor 21 generates an initial resistance moment under the control of the controller 23, so that the driving sprocket 41 is decelerated to rotate at a rotation speed V2. The controller 23 then determines whether the rotation direction of the drive sprocket 41 is changed by the encoder, and if so, reduces the resistance torque output by the motor 21, and if not, calculates the difference between the rotational speed V1 and the rotational speed V2, and if the difference is smaller than a preset threshold, increases the resistance torque output by the motor 21.
In the resistance mode, the drive sprocket 41 rotates at a rotational speed V3 by the initial driving torque output from the motor 21, and the drive sprocket 42 decelerates to rotate at a rotational speed V4 when the force applied to the operation member 3 by the exerciser is transmitted by the chain 42. The controller 23 then determines whether the rotation direction of the drive sprocket 41 is changed by the encoder, if so, increases the driving torque output from the motor 21, if not, calculates the difference between the rotation speed V3 and the rotation speed V4, and if the difference is smaller than a preset threshold, decreases the driving torque output from the motor 21.
The man-machine intelligent terminal 5 is fixedly installed at a position suitable for human operation, and the man-machine intelligent terminal 5 can perform data interaction with the remote APP terminal 6.
The working steps of the resistance mode of the fitness equipment are as follows:
Referring to fig. 2, at an initial time, the operating member 3 is located at the limiting member a. The exerciser holds the grip 32 by hand or pedals the pedal plate 31, so as to apply a force Fr to the operation member 3, the direction of the force Fr is shown in fig. 2, so that the operation member 3 is pushed to generate a motion with a speed direction Vr, the motion is moved towards the direction of the limit member B, and the position of the limit member B is the motion end point in the resistance mode. At this time, the operating member 3 moves the chain 41 such that the chain 41 generates a movement with a speed direction Vr'. At this time, the motor 21 generates a resistance moment Tr, and the resistance moment Tr can be adapted to the change of the force Fr applied by the exerciser, and the exerciser feels resistance to push the operation member 3 to move at a uniform speed, thereby achieving the exercise purpose.
The working steps of the resistance mode of the fitness equipment are as follows:
with reference to fig. 3, after the end of the resistance mode, the operating member 3 is located at the limiting member B. The motor 21 generates a driving torque Tp and causes the chain 42 to generate a movement speed in the direction Vp, so as to drive the operating member 3 to move in the speed direction Vp' and to the position of the limiting member a, which is the end of the movement in the resistance mode. While the exerciser exerts the resisting force Fp on the operating member 3 and tries to resist the movement of the operating member 3, the driving torque Tp output by the motor 21 can be adaptively adjusted according to the resisting force Fp. The operation part 3 is resisted by the body builder to continue uniform motion so as to achieve the body builder to achieve the body building purpose.
