Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, and further can be used to test testing devices such as active and passive training equipment, fitness power bikes, medical power bikes and the like. Background Art

[0002] In the development process of various fitness equipment (including high-end power bikes, exercise bikes, crank fitness equipment and rehabilitation equipment), it is necessary to control the power output of the product, especially when connected to a cardiopulmonary assessment test system. Therefore, a power calibration device is extremely important and necessary.

[0003] The patent "A motor output torque tester" (CN216246954U) provides a hysteresis damper to control the external load, install the motor on the flange seat, drive the motor to rotate, and control the damping size by adjusting the hysteresis damper controller. The dynamic torque sensor displays the real-time measured torque value. This device is suitable for testing devices with internal power. However, it cannot test the power of unpowered devices.

[0004] The patent "A dynamic torque sensing test device with an adjustable base" (CN216410463U) provides a method for adjusting the installation problem in the dynamic torque sensor, and can adjust the height according to the different sizes of the test body, and can easily adjust the coaxiality of the dynamic torque sensor.

[0005] Both of the above solutions can only test the torque of powered equipment, but cannot test the power of crank-type equipment.

[0006] Based on this, the inventor has devoted himself to the research on solving this practical problem and developed a new type of "a multi-purpose ergometer for fitness equipment". Utility Model Content

[0007] The purpose of the utility model is to provide a multi-purpose dynamometer for fitness equipment, which can test the power of both equipment with power and equipment without power, so as to achieve more convenient and accurate power measurement.

[0008] The purpose of the utility model is achieved through the following solutions:

[0009] A multi-purpose ergometer for fitness equipment comprises a base, a leveling module and a detection device, characterized in that: 2-3 leveling modules are arranged above the base, the leveling module is divided into an upper part and a lower part, the upper and lower parts are connected by a lifting adjustment knob, the lifting adjustment knob can make the upper part of the leveling module rise and fall relative to the lower part; a horizontal adjustment knob is arranged between the lower part of the leveling module and the base, the horizontal adjustment knob can make the leveling module move left and right, front and back to position; the detection device comprises: the front part of the servo motor is connected to a planetary reducer, a coupling A, a torque sensor, a coupling B, and a connecting device in sequence, wherein the bracket is supported at coupling B.

[0010] further:

[0011] The lower part of the leveling module is fixed on the bottom plate, and the bottom plate is movably connected to the base through a horizontal adjustment knob.

[0012] The upper part / lower part of the leveling module is in an inverted U shape and is buckled on the lower part / upper part.

[0013] The coupling A and coupling B are both flexible universal couplings.

[0014] The torque sensor is a dynamic torque sensor.

[0015] The servo motor is provided with a controller.

[0016] The beneficial effects of the utility model are: 1. The utility model achieves a high degree of coaxiality with the output shaft of the test device, and adopts a servo motor as a power source, which can provide both power and resistance to the outside. Therefore, the power of power-equipped equipment can be tested, and the power of non-powered equipment can also be tested. 2. Fine control of the motor is performed by introducing a servo system: A. A high-precision torque sensor is added to more accurately sense changes in external force, so that power can be measured more conveniently and accurately. B. The resistance can be precisely controlled, and closed-loop control can be performed more conveniently with its dynamic torque sensor. C. The speed is controlled and adjusted, and it is stepless speed regulation. The power can be adjusted more smoothly.

[0017] In order to enable those skilled in the art to better understand the present invention and to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the present invention is further described in detail below in conjunction with embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a schematic diagram of the structure of the utility model.

[0019] In the figure: base 1, leveling module 2, servo motor 3, controller 4, planetary reducer 5, coupling A6, torque sensor 7, coupling B8, bracket 9, connecting device 10, horizontal adjustment knob 11, lifting adjustment knob 12. DETAILED DESCRIPTION

[0020] like Figure 1 As shown, a multi-purpose ergometer for fitness equipment comprises the following parts: three leveling modules 2 are arranged above an adjustable base 1, and a horizontal adjustment knob 11 is arranged at the bottom of the leveling module 2. By adjusting the horizontal adjustment knob 11, the position of the leveling module 2 is moved and positioned. The leveling module 2 is divided into two parts, the upper part is in an inverted U shape and buckled on the lower part; the lower part is fixed on the bottom plate, and the bottom plate is movably connected to the base 1. The connection point between the bottom plate and the base 1 is provided with a horizontal adjustment knob 11, and the horizontal adjustment knob 11 moves the front and rear position of the bottom plate and positions it.

[0021] The upper part and the lower part of the leveling module 2 are movably connected, and a lifting adjustment knob 12 is provided at the connection point. By adjusting the lifting adjustment knob 12, the leveling module 2 can be lifted and lowered. The front part of the servo motor 3 is connected to the planetary reducer 5, the coupling A6, the torque sensor 7, the coupling B8, and the connecting device 10 in sequence, wherein the bracket 9 is supported at the coupling B8.

[0022] The controller 4 is placed above the servo motor 3 and controls the motor.

[0023] The coupling A6 and the coupling B8 are both flexible universal couplings.

[0024] The torque sensor 7 is a dynamic torque sensor.

[0025] The bracket 9 is mainly used for reinforcement and is connected to the external tested device for enhanced fixation.

[0026] The connecting device 10 is a flange.

[0027] Since the utility model and the output shaft of the test device are kept on the same horizontal plane and coaxial, when in use, the connecting device 10 of the device is coaxially connected to the crank-type device, and the leveling module 2 is used for coarse adjustment through the left and right adjustment knobs 11 and the lifting adjustment knobs 12, and then the flexible universal coupling is used to have a certain tolerance for coaxiality to achieve coaxiality. The device can provide power to the outside to drive active devices to move, such as driving a power car to rotate, and it can control the speed well, thereby obtaining stable power for testing the power variation rate.

[0028] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
