Description

Human-type treadmill capable of setting sport speed

The present invention relates to a treadmill of sports equipment, and more specifically, to a manual treadmill. (Note: The term "treadmill" is used in this case to refer to this type of sports equipment. It is not intended to limit its use or to be used for running sports, but also includes similar sports equipment mainly used for walking sports.)

A treadmill is a very common sports equipment that can be used for walking or running on a looped endless belt (commonly known as a running belt). In terms of the power to drive the rotation of the aforementioned endless belt, treadmills can be roughly divided into two types: powered treadmills and human-powered treadmills. The former is driven by an electric motor or other power device to drive the endless belt, and the latter is The endless belt is driven to rotate by the force of the user.

Generally speaking, the power running opportunity displays the rotation speed of the aforementioned endless belt on its meter (Note: corresponds to the speed at which the user walks or runs on the endless belt, hereinafter also referred to as exercise speed, and the common unit is " Km/h” or “mile/h”), and can be used by the user to set the aforementioned movement speed through the input device, and then continuously control the power output of the power device (such as controlling the motor speed) during the user’s movement to drive the ring The belt rotates cyclically according to the speed set by the user. Powered treadmills account for a relatively majority in the current market, meaning that more people use power treadmills for indoor walking or running. Based on the characteristics that the rotation of the endless belt can be accurately controlled by the power device, users Usually set a suitable exercise speed (or exercise program) exercise for a fixed period of time, in order to control the quantitative intensity of each exercise and calorie consumption.

In contrast, a human-type treadmill cannot drive and control the rotation of the endless belt. The user must use the walking or running action of the user on the top surface of the endless belt to continuously apply the The forward and backward force drives the endless belt to rotate cyclically. Among them, the movement of the user during movement, such as whether the two hands grasp the grip on the front of the treadmill or the armrests on both sides (to increase or decrease the force applied by the foot) Fast or slow, large or small steps, etc., how much will affect the ring The rotation speed of the belt. In addition, if the human-shaped treadmill with a concave arc shape on the top surface of the endless belt body, such as the technology disclosed in US Patent No. 8,343,016, the front and back positions of the user on the top surface will also affect the ring The speed of rotation of the belt. At the same time, many manual treadmills are equipped with a resistance adjustment device that can apply resistance to the rotation of the endless belt. The user can manually select the appropriate resistance according to personal conditions and the type of exercise performed. For example, the resistance used when running is usually less than The resistance used when walking; conversely, adjusting the aforementioned resistance will change the movement speed under the same action or the same output. However, for users, changing their movements, front and back positions, and/or adjusting the aforementioned resistance, etc., basically just change the relative degree of the movement speed (for example, make the speed "faster" or "slower"), It is impossible to determine the absolute value of the speed of movement (for example, to maintain the speed at 10 km/h). From this point of view, it is difficult for the human-type treadmill to meet the quantification of controlling movement by walking or running at a specific speed. Users of strength and calories. A small number of human-based running opportunities continue to sense and display the rotation speed of the endless belt, which improves the above problems to a certain extent. However, even if the user can know the current movement speed at any time during the exercise, he wants to change himself Movements, forward and backward positions, and/or adjust the aforementioned resistance, arbitrarily accelerate or slow down from the current movement speed to a specific speed, and then maintain the specific speed (until you want to change to another specific speed or end the movement), In fact, it is not easy, and it will make users unable to concentrate on sports and enjoy sports.

U.S. Patent No. 8,007,408 discloses a human-powered treadmill that can help control the movement speed at a set value, wherein the control unit of the treadmill can control the elevation angle of the treadmill (with the endless belt) through an electronic control mechanism, Moreover, the control unit will monitor the rotation speed of the endless belt (ie, the movement speed) when the user is exercising. If the current movement speed is slower/faster than the set speed, it will control the treadmill (along with the endless belt (Body) increase/decrease the elevation angle to increase/decrease the component of the user's downward force in the direction of the top surface movement of the endless belt, thereby accelerating/decreasing the speed of rotation of the endless belt, Make the movement speed approach or accord with the set speed. However, according to the uncovered technology, if you want to change the speed of movement, you must change the elevation angle of the top surface of the endless belt (hereinafter also referred to as the sports surface), which undoubtedly limits the freedom and selectivity of using a treadmill to walk or run. Specifically, the user cannot accelerate from walking to running, or decelerates from running to walking while the angle of the sports surface remains unchanged, or choose to exercise on a sports surface with a relatively low elevation angle Relatively fast motion, relatively slow motion on a moving surface with a relatively high elevation angle.

The main purpose of the present invention is to provide a human-type treadmill, which can be used by the user to set the exercise speed according to personal needs, and to assist the user in walking or running at the set speed.

Another object of the present invention is to provide a human-powered treadmill, which can be used by a user to set a movement speed according to personal needs, and to assist the user in walking or running at a set speed, wherein when the movement speed changes, the user The angle of the moving surface under the foot can be kept constant, or as long as the set speed is a priority, it can be kept as constant as possible.

Another object of the present invention is to provide a human-powered treadmill, which can be used by the user to set the angle and speed of the sports surface according to personal needs, and to assist the user to walk or run at the set speed at the set angle .

In order to achieve the above-mentioned purpose, the human-powered treadmill provided by the present invention includes: a frame body; an endless belt body, which is rotatably provided on the frame body and can be used by a user on the top surface Walking or running, and can be rotated by the user applying a force from the front to the back of the top surface; the predetermined section of the top surface of the endless belt body forms a main force area, the top surface is at least The main force zone appears to extend from the upper front to the lower back; a sensing device that can sense the parameters corresponding to the rotational speed of the aforementioned endless belt and generate a corresponding speed signal; an input device for the user The input contains an instruction to set the rotation speed of the endless belt, and generates a corresponding indication signal; a resistance adjustment device can generate resistance that hinders the rotation of the endless belt, and can be controlled by a first control signal to change the aforementioned The magnitude of the resistance; a control unit that can receive the speed signal from the sensing device to obtain a current speed value, receive the indication signal from the input device to obtain a target speed value, and generate a control speed The first control signal of the resistance adjusting device; at least at a certain time in a control mode, the control unit may control the resistance adjusting device to reduce the resistance because the current speed value is lower than the target speed value, or because of the foregoing The current speed value is higher than the target speed value and the resistance adjustment device is controlled to increase the resistance. Thereby, without the user's own control, the rotation resistance of the endless belt body will be automatically reduced/increased because the current rotation speed is slower/faster than the speed set by the user, so that the endless belt body is under the same force The speed increases/decreases, so it approaches or matches the speed set by the user.

Preferably, during a period of time in the aforementioned control mode, the aforementioned control unit Repeat the comparison between the current speed value and the target speed value. Whenever the current speed value is lower than the target speed value and the resistance has not reached the lower limit of the adjustable range, the resistance adjustment device is controlled to reduce the resistance, otherwise, whenever When the current speed value is higher than the target speed value and the resistance has not reached the upper limit of the adjustable range, the resistance adjustment device is controlled to increase the resistance. Thus, during this period, even if the user's force on the endless belt body changes, the rotation speed of the endless belt body can still remain close to or meet the speed set by the user.

Preferably, the control unit estimates the rotation speed of the endless belt when the resistance is adjusted to the lower limit of the adjustable range according to the variation relationship between the resistance and the current speed value, and accordingly corrects the input device The current user can set the upper limit of the rotational speed of the endless belt. In this way, the user can grasp the upper limit of the individual's possible movement speed, and the user experience is better.

Preferably, the frame body includes a fixed frame and a movable frame that can change position relative to the fixed frame; the endless belt body is at least partially provided on the movable frame, when the position of the movable frame relative to the fixed frame changes At this time, the elevation angle of the front end of the main stress area of the endless belt relative to the rear end will also change; an elevation angle adjustment device is provided between the fixed frame and the movable frame and can be controlled by a second control signal The movable frame is driven to change its position relative to the fixed frame; the control unit can generate the second control signal for controlling the elevation angle adjusting device. Thereby, the user can move at the set speed under different aforementioned elevation angles.

Preferably, at least for a certain time in a control mode, the control unit may control the elevation angle adjustment device to increase the elevation angle because the current speed value is lower than the target speed value, or because the current speed value is higher than The target speed value controls the elevation angle adjustment device to reduce the elevation angle. By this, in addition to the above-mentioned resistance will automatically increase and decrease, the above-mentioned elevation angle will automatically increase/decrease because the current rotation speed of the endless belt is slower/faster than the speed set by the user, so that the downward force of the user is in the ring The component force in the direction of movement of the top surface of the belt (especially the main force area) increases/decreases, which accelerates/decreases the speed of rotation of the endless belt, thus approaching or conforming to the user's setting speed.

Preferably, in a control mode, if the current speed value is lower than the target speed value, and the resistance has reached the lower limit of the adjustable range and the elevation angle has not yet reached the upper limit of the adjustable range, the control unit will control the The elevation angle adjustment device increases the aforementioned elevation angle. In this way, after the aforementioned resistance is minimized, the movement speed may continue to increase.

Preferably, before the resistance has not reached the lower limit of the adjustable range, the control unit will not actively control the elevation adjustment device. In this way, unless the aforementioned elevation angle is changed to achieve the speed set by the user, otherwise the aforementioned elevation angle will not be automatically changed.

Preferably, the input device allows the user to input an instruction including setting the elevation angle; when the control unit receives the instruction signal including setting the elevation angle, it will control the elevation angle adjustment device so that the elevation angle conforms to the user's instruction . In this way, the user can choose to move at a specific speed at a specific elevation angle.

Preferably, the input device allows the user to select one of the exercise intensity from a plurality of exercise intensity, each of the exercise intensity preset a elevation angle value and a speed value; when the control unit receives the instruction containing the specified exercise intensity After the signal, the elevation angle adjustment device is controlled so that the elevation angle conforms to the elevation angle value preset by the exercise intensity, and the velocity value preset by the exercise intensity is used as the target velocity value. In this way, the user can quickly increase or decrease the overall intensity of the exercise in stages.

Preferably, the control unit estimates the change when the resistance is adjusted to the lower limit of the adjustable range and the elevation angle is adjusted to the upper limit of the adjustable range according to the variation relationship of the resistance, the elevation angle and the current speed value The rotation speed of the endless belt can be modified to allow the user to set the upper limit of the rotation speed of the endless belt. In this way, the user can grasp the upper limit of the individual's possible movement speed, and the user experience is better.

And FIG. 11 is a flowchart of a control mode of the human-powered treadmill according to the second preferred embodiment of the present invention.

Please refer to FIG. 1 and FIG. 2 first, the human-powered treadmill according to the first preferred embodiment of the present invention has a frame body 10 fixed by a plurality of metal aggregates. The frame body 10 mainly includes a stable support on the ground The base 11, the left and right front pillars 12 extending upward from the left and right sides of the front end of the base 11, the left and right rear pillars 13 extending upward from the left and right sides of the rear end of the base 11, respectively The left and right side rods 14 between the top of the front pillar 12 on the left and right sides and the top of the rear pillar 13 and a front frame 15 connected between the top of the left and right front pillars 12. Among them, the base 11 serves as a treadmill skeleton of the treadmill, and its footprint area generally has a long front and rear, short left and right rectangles, and a sports space S is formed above it, and the rear end of the sports space S has an entrance (note: Located between the left and right rear pillars 13 (not labeled), allowing the user to enter the sports space S forward from the rear of the treadmill and exit the treadmill from the sports space S backward.

The front end and the rear end of the base 11 are provided with a front drum 21 and a rear rear cylinder 22 which can rotate in situ according to their own axes, the axis (first axis) A1 of the front drum 21 and the axis (first Both axes) A2 correspond to the left and right axes. An endless belt body 23 wraps around the front roller 21 and the rear roller 22 at the same time with appropriate tension, so that it can rotate on the base 11 in a front-back direction along the front and back directions, and the front roller will be driven together when rotating 21 and the rear drum 22 rotate in place. As shown in FIG. 2, the height of the front drum 21 from the ground is higher than that of the rear drum 22, so that the top surface of the endless belt 23 forms a slope with a high front and a low rear. The user can walk or run on the inclined top surface of the endless belt 23, such as jogging, brisk walking, jogging, fast running, walking backwards, running backwards, sideways, etc. Under normal usage, the user The above-mentioned various movements are carried out by using the feet to exert force on the top surface of the endless belt 23 from the higher front end to the lower rear end, where the back or running is facing the back of the treadmill , When walking sideways, it is facing the side of the treadmill. In the ring There is a flat plate 26 fixed on the base 11 between the top surface and the bottom surface of the belt 23, the top surface of the flat plate 26 is parallel to the top surface of the endless belt 23 to support the user to step on the endless belt 23 the weight of.

As shown in FIG. 1, the human-powered treadmill according to the preferred embodiment may optionally be provided with a blocking device 30 in the aforementioned motion space S. The blocking device 30 is generally a Y-shaped belt-shaped body. It can be detachably connected between the center of the front frame 15 of the frame body 10 and the top ends of the left and right rear pillars 13 and stretched at an appropriate height above the endless belt 23 when the user enters the sports space S to walk or When running, the blocking device 30 can block the user's waist to block its progress, so that the user can use the reaction without grasping the grip or armrest of the frame body 10 (such as the appropriate part of the front frame 15 or the side bar 14) The force enhances the backward thrust of the foot against the top surface of the endless belt 23, so that it can walk or run with natural movements like outdoor sports. The application of the aforementioned blocking device 30 on the human-powered treadmill is the prior art, and the relevant details can be found in the description of the patent No. I593444 in my country. However, for the human-powered treadmill of the present invention, it is not necessary to assist the user to push the aforementioned blocking device 30 of the endless belt 23 or even the grip or armrest on the frame body 10. In other words, when using the human-powered treadmill of the present invention for walking or running, the user may not need to grasp the frame body or lean forward against the blocking device to generate a reaction force. The downward force of the body weight alone is in the endless belt The component force in the moving direction of the top surface of the body 23 can drive the aforementioned top surface to move from the higher front end to the lower rear end.

An instrument cluster 40 is provided in the center of the front frame 15 of the rack body 10, and the instrument cluster 40 has a display device 41 for displaying various information for the user to view, and a first input device for the user to input various instructions 42. The display device 41 and the first input device 42 shown in the figure are only schematic, and the specific structure in practice can be selected from a variety of conventional devices or used in combination. For example, the display device 41 may include: a character display (such as seven segments /9-segment/14-segment/16-segment display), dot matrix display, liquid crystal display, etc., and the first input device 42 may include: buttons, knobs, sliders, levers, touch switches, non-contact Switch, touch screen, etc.

The user can input an instruction including setting the rotation speed of the endless belt 23 (or the user's movement speed) through the first input device 42. For example, as in setting the movement speed on a general power treadmill, the user May use the numeric keys provided by the first input device 42 or so-called "quick keys" to specify a specific speed (eg "10 km/h"), and use the "plus key" or "minus key" instructions to speed up or slow down Speed (for example, each press increases or decreases 0.5 km/h), Or use a variety of input methods to select or edit a sport program that has a set length of time and the motion speed can be changed according to time sequence. Among them, the setting content of a sport program is exemplified as follows: the total length of time is 30 minutes, divided by 2 minutes as 15 periods, the movement speed in each period is 2, 4, 4, 6, 6, 8, 8, 10, 8, 8, 6, 6, 4, 4, 2 km/h, and so on. Moreover, the first input device 42 is for the user to input an instruction including the set exercise speed, and also includes a situation where the user may not know the specific value of the set exercise speed. For example, the user only chooses to perform "walking for 15 minutes" or "jogging" The exercise intensity such as "30 minutes" or the exercise intensity such as "Level 1" and "Level 2" is not clear about the specific value of the preset exercise speed for each stroke/intensity. In this preferred embodiment, a second input device 43 and a third input device 44 are also provided at the top of the left and right front pillars 12 of the frame 10, respectively, so that the user can more conveniently perform common Speed indication, for example, the second input device 43 is provided with "warm-up" and "cool-down" buttons corresponding to a preset speed, and the third input device 44 is provided with acceleration and Deceleration "plus key" and "minus key". Hereinafter, the first input device 42, the second input device 43, and the third input device 44 are collectively referred to as "input devices".

During the exercise of the user, the display device 41 may continue to display or, if necessary, the following information: the exercise speed and/or exercise program set by the user (for example, the temporal change of the exercise speed graphically presented), the endless belt 23 The current rotation speed (that is, the current movement speed of the user), the exercise time so far, the movement distance so far, and the calorie consumption so far. The rotation speed of the endless belt 23 or the movement speed of the user can be obtained by measuring the rotation speed of the front drum 21 or the rear drum 22 and then converting it, which will be further described later. In addition, the aforementioned movement distance can be obtained by measuring the number of rotations of the front drum 21 or the rear drum 22 and then converted, and the aforementioned calorie consumption can be calculated and accumulated based on the parameters such as the movement speed and the movement time or the movement distance through a preset formula Out, are the prior art in the field of treadmills.

Please refer to FIG. 3 and FIG. 4, the left end of the front roller 21 coaxially protrudes a rotating shaft 27, and the outer end of the rotating shaft 27 is coaxially fixed to a flywheel 28 made of a metal material. The flywheel 28 rotates synchronously with the front roller 21 to increase the front roller The moment of inertia during the 21-site rotation makes the endless belt 23 driven by the front drum 21 relatively stable and smooth during the cyclic rotation.

Please refer to FIG. 5 again. A resistance adjusting device 50 is provided near the left end of the front roller 21 to generate resistance that hinders the rotation of the front roller 21 (and the endless belt 23). The resistance adjusting device 50 mainly includes a metal disc 51. A stepping motor 52, a deflection seat 53 and two permanent magnets Iron 54, wherein the metal disc 51 is coaxially fixed on the rotating shaft 27, and will rotate with the front drum 21 in-situ; the deflection seat 53 is pivotally mounted on the base 11 according to a third axis A3 corresponding to the left and right axial directions, It is located near the front edge of the metal disc 51; the two permanent magnets 54 are respectively disposed on two opposite inner walls of a U-shaped part of the deflection seat 53, and the two are opposed to each other and form a gap therebetween. The position matches the position of the axial thickness of the metal disc 51, in other words, the front edge of the metal disc 51 can partially enter between the two permanent magnets 54; the stepping motor 52 is installed on the base 11, and its basic step angle (step angle) is 0.9 degrees, the deflecting seat 53 can be driven according to the third axis A3 in the position drawn by the solid line in FIG. 4 (hereinafter referred to as the outermost position) and the position drawn by the imaginary line (hereinafter referred to as the innermost position) The deflection seat 53 can be deflected within the range of nearly 60 degrees, and the deflection seat 53 can be stopped at one of the 64 predetermined positions (including the aforementioned outermost position and innermost position) equally divided within the aforementioned angle range; The deflection in the direction of the aforementioned outermost position (clockwise rotation in FIG. 4), the side of the two permanent magnets 54 and the metal disc 51 overlap side view is less, until there is no overlap at all; the deflection seat 53 toward the innermost position Deflect in the direction of (the counterclockwise rotation in FIG. 4), the more the aforementioned overlapping area is, until the permanent magnet 54 completely faces the metal disc 51. To put it simply, the resistance adjusting device 50 of this preferred embodiment is essentially an eddy current brake, that is, when the metal disc 51 enters between the two permanent magnets 54 relatively, the rotating metal circle An eddy current resistance that hinders rotation is generated between the disc 51 and the stationary permanent magnet 54, and when the endless belt 23 rotates cyclically, the metal disc 51 is driven to rotate in place at a corresponding rotation speed, so the aforementioned eddy current resistance becomes an obstacle One of the resistances of the endless belt 23 to rotate cyclically. The magnitude of the aforementioned eddy current resistance changes with the overlapping area of the permanent magnet 54 and the metal disc 51. In this example, since the stepping motor 52 can adjust the angular position of the deflection seat 53 in 64 steps, the aforementioned resistance adjustment The device 50 can theoretically finely adjust the rotational resistance of the endless belt 23 from a minimum to a maximum of 64 steps.

Of course, in addition to the above-mentioned uncovered structure and adjustment method, the resistance adjustment device of the present invention can also adopt various other possible implementation structures and adjustment methods, including but not limited to the following examples: First, the same is an eddy current brake, but by position The fixed electromagnet replaces the permanent magnet that is movable in the aforementioned position. By controlling the magnitude of the current flowing through the electromagnet to control the strength of the magnetic field, the eddy current resistance between the metal disc and the electromagnet can be adjusted. Second, a generator is provided (The structure is like a DC motor). When the front drum or the rear drum rotates, the rotor of the generator is rotated, and the power output of the generator is connected to a load circuit. By controlling the load of the generator, the front can be adjusted. Rotational resistance of the roller or the rear roller; third, friction resistance as the source of resistance, such as setting Once contacting the friction block of the flywheel, and driving the friction block against or loosening the flywheel with an electronically controlled actuator, the rotational resistance of the flywheel can be adjusted. For example, a friction belt wound around the circumference of the flywheel is provided. One end is fixed, the other end can be pulled or loosened by an electronically controlled actuator, and the rotation resistance of the flywheel can also be adjusted. Others such as wind resistance, water resistance, oil pressure resistance, etc. may also be used as the source of resistance of the resistance adjustment device.

Referring to FIG. 5, a power generating device 70 is provided near the right end of the front drum 21 (left side of FIG. 5 ). The structure of the foregoing power generating device 70 is like a DC motor, and the outer end of the rotor is coaxially fixed to a small pulley 71; correspondingly, the front drum 21 The right end of the shaft is coaxially fixed with a large pulley 72. A transmission belt 73 is sleeved between the large pulley 72 and the small pulley 71, so that the front drum 21 rotates in place to drive the rotor of the generator 70 to rotate at a faster speed. When the rotation speed is fast enough, the power generating device 70 can generate the corresponding power. The aforementioned power is transmitted to a power storage device (not shown) for temporary storage, and then provided to the electronic or motor type device on the treadmill that requires power to work, such as The display device 41, input devices 42, 43, 44, resistance adjustment device 50, and the like. Of course, the human-powered treadmill of the present invention may also be equipped with other power supply modules or even an external power supply, so that all electronic and motor devices can obtain sufficient power at any time.

Since the faster/slower the speed of the front drum 21 driven by the endless belt 23 is, the higher/lower the output current or output power of the power generator 70, therefore, the parameters such as the current or power of the power generator 70 can be converted The rotation speed of the endless belt 23, that is to say, the structure of the aforementioned power generation device 70 and the front drum 21 connected to the power generation device 70 via a belt transmission mechanism, constitutes a sensing device that can sense the rotation speed of the endless belt 23装置80。 The device 80.

Of course, in addition to the above-mentioned uncovered structure and sensing method, the sensing device of the present invention can also adopt various other possible structures and sensing methods, including but not limited to the following examples: light sensing, magnetic sensing, and image Sensing, etc., to sense the rotation speed of the front roller 21 or the rear roller 22 (or a member that rotates with the front roller 21 or the rear roller 22, such as the aforementioned flywheel 28, metal disc 51, large pulley 72, etc.), by The rotation speed of the endless belt 23 is converted from the aforementioned rotation speed. A more specific solution is as follows (not shown in the figure): a grating disk that rotates with the front drum 21 is provided, and a number of openings arranged at equal intervals along the circumference are provided near the outer edge of the aforementioned grating disk, and the grating A fixed light emitter and a light receiver are respectively arranged on both sides of the disc. By measuring the frequency of the light emitted from the light emitter to the light receiver through the opening, the rotation speed of the grating disk can be known. Furthermore, the rotational speed of the endless belt 23 is converted, for example, assuming that the grating disk and the front drum 21 The rotation speed ratio of 1:1 is known, and the circumference of the front drum 21 is known to be 25 cm. Then, when the rotation speed of the grating disk is 300 rpm (equal to 18000 rpm), the rotation of the endless belt 23 can be estimated The speed is 4.5 km/h. In general, in the present invention, the sensing device can sense a parameter corresponding to the rotational speed of the endless belt and generate a corresponding speed signal, which may be a signal that has not been converted ( For example, the pulse signal generated by the aforementioned light receiver being excited may also be a signal that has been converted (for example, an analog or digital signal that can correspond to a speed value).

FIG. 6 is a schematic diagram of the structure of the human-powered treadmill of the preferred embodiment, in which a user U is shown walking or running on the top surface 24 of the endless belt 23, and the user U in motion usually steps on the aforementioned Within a predetermined section of the top surface 24 (hereinafter referred to as the main force-bearing area) 25, the main force-bearing area 25 is a front-to-back slope, allowing the downward force of the user U to be generated along the slope from front to top The lower and rear component force is beneficial for the user U to apply a force from the front to the back of the top surface 24 of the endless belt 23, so that the endless belt 23 rotates in a corresponding direction. During the exercise, the resistance adjusting device 50 may generate resistance that prevents the endless belt 23 from rotating cyclically (it is also the resistance that the user U needs to drive the endless belt 23 for walking or running), and the aforementioned sensing device 80 can sense the rotation speed of the endless belt 23 (that is, the movement speed of the user U walking or running on the endless belt 23).

The aforementioned human-powered treadmill also has a control unit 60, which can perform calculations, judgments, and controls in accordance with preset rules. The specific structure in practice mainly includes a programmable microprocessor and a memory that can access data. The body is usually installed inside the instrument cluster 40, and is electrically connected to the display device 41, the input devices 42, 43, 44, the resistance adjustment device 50, and the sensing device 80 by wire or wirelessly. When a user inputs an instruction through the input devices 42, 43, and 44, the input devices 42, 43, and 44 generate a corresponding instruction signal and send it to the control unit 60. The control unit 60 performs the corresponding processing, in which, when the instruction signal corresponds to When the instruction for setting the rotation speed of the endless belt 23 is included, the control unit 60 can obtain a target speed value therefrom, that is, the specific value of the movement speed set by the user (including the value directly indicated by the user, and the value indirectly indicated by the user) The corresponding preset value). The control unit 60 also receives the aforementioned speed signal from the sensing device 80 and thereby obtains a current speed value, that is, a specific value of the current rotation speed of the endless belt 23. The control unit 60 can use a first control signal to control the resistance adjusting device 50 (for example, to control the driving circuit of the stepping motor 52) to change the resistance. Control sheet The element 60 can control the display device 41 to display specific information, such as the aforementioned target speed value, current speed value, current exercise time, current exercise distance, current calorie consumption, etc. The working power source of the control unit 60 may come from the aforementioned power generation device 70 and power storage device, or it may partially or completely use the power supplied at any time, without relying on the user U to generate power.

FIG. 7 shows the basic flow of a control mode of the aforementioned human-powered treadmill. In simple terms, in this control mode, the control unit 60 repeatedly repeats the current speed value and the target speed value that are likely to change. Whenever the current speed value When it is lower than the target speed value and the aforementioned resistance has not reached the lower limit of the adjustable range, that is, the resistance adjustment device 50 is controlled to reduce the resistance. On the contrary, whenever the current speed value is higher than the target speed value and the aforementioned resistance has not reached the upper limit of the adjustable range, That is, the resistance adjusting device 50 is controlled to increase the resistance. The following will further explain each program and its flow in FIG. 7, where the branch after the judgment program (diamond box), "Y" stands for "Yes", and "N" stands for "The judgment result is No".

The "mode activation" referred to in the program 101 may include two conditions, one is that the control unit 60 starts to run this control mode in response to an instruction input by the user, and the other is that the control unit 60 is not automatically selected by the user according to a preset rule. Run this control mode, for example, the latter automatically runs this control mode whenever the system obtains working power or restarts, and for example, when the control unit 60 determines that a user has started to move on the endless belt 23 based on the change of the aforementioned speed signal This control mode is run automatically.

When the control mode starts to run, that is, the program 102, the control unit 60 will first substitute a preset speed value into the target speed value as a temporary target before the user sets the motion speed. Based on safety considerations, the aforementioned preset speed value is preferably a relatively slow movement speed, such as the speed at which an average person walks, such as 4 km/h.

Next, in the program 103, the control unit 60 determines whether an instruction signal containing the set motion speed from the input device 42, 43, 44 is newly received (for example, corresponding to the user designating a specific speed, instructing to speed up or slow down) Motion speed, instructions for selecting a motion program to execute, etc.), and, if the motion program previously selected by the user is currently being executed, it is also necessary to determine whether the timing of the motion speed set according to the motion program changes, and whether the motion speed should be changed at this time; If there is a need to change the target speed value, enter the program 104 first, the control unit 60 will change the existing target speed value to the new target speed value according to the latest input instruction or according to the setting of the motion program, and then enter the program 105; Otherwise, maintain the current target speed value and go directly 入程序105。 105 into the program.

In program 105, the control unit 60 compares the aforementioned current speed value with the target speed value to determine whether the current speed value is less than the target speed value (or less than a predetermined degree, for example, 0.1 km/h), if yes, enter program 107 ; Otherwise, enter procedure 106.

From the aforementioned procedure 105 to the procedure 106, it indicates that the current speed value is not less than the target speed value (or not less than the predetermined level), the control unit 60 will then determine whether the current speed value is greater than the target speed value (or greater than a predetermined level, For example, 0.1 km/h), if it is, enter the program 110; otherwise, it means that the current speed value is equal to the target speed value (or the difference between the two is within a predetermined degree), the flow returns to the foregoing program 103, and re-judge whether there is a change in the target speed value need.

From the aforementioned procedure 105 to the procedure 107 (located on the left half of the flowchart), indicating that the current speed value is less than the target speed value (or smaller than the aforementioned predetermined degree), the control unit 60 will further determine whether the current resistance of the resistance adjusting device 50 has reached the In this example, the lower limit of the adjustment range is to determine whether the deflection seat 53 is at the outermost position (FIG. 4). If yes, proceed to procedure 109; otherwise, proceed to procedure 108. In the program 108, the control unit 60 controls the resistance adjusting device 50 to reduce its resistance. In this case, the deflection seat 53 is controlled to deflect toward the outermost position. Then, the flow returns to the program 103 to re-determine whether there is a change The need for target speed values.

Symmetrically, from the program 106 to the program 110 (located on the right half of the flowchart), indicating that the current speed value is greater than the target speed value (or greater than the predetermined level), the control unit 60 will further determine the current resistance of the resistance adjustment device 50 If the upper limit of the adjustable range has been reached, in this case, it is to determine whether the aforementioned deflection seat 53 is located at the aforementioned innermost position, and if so, enter program 112; otherwise, enter program 111. In program 111, the control unit 60 controls the resistance adjusting device 50 to increase its resistance. In this case, the deflection seat 53 is controlled to deflect in the direction of the innermost position. Then, the flow returns to the program 103 to re-determine whether there is a change The need for target speed values.

In detail, the control unit 60 controls the reduction of resistance in the aforementioned program 108 and the increase of resistance in the aforementioned program 111. There are two different methods of implementation. The first method is that the control unit 60 will be in the program 108/program 111 Continue to control the decrease/increase of resistance, and make the endless belt 23 increase/decrease in rotation speed due to the decrease/increase of rotation resistance until the current speed value is equal to the target speed value (or the difference between the two is within a predetermined degree), or Is the resistance during control The lower limit or upper limit of the adjustable range has been reached before entering the next procedure, that is, returning to the aforementioned procedure 103; the second method is that the control unit 60 only controls the resistance reduction/increase by a predetermined amount in the procedure 108/program 111 each time Degree, and usually a small adjustment, for example, to control the deflection seat 53 of the resistance adjusting device 50 to be shifted by one position in the direction of the outermost position/innermost position (that is, to adjust 1/64 of the range), and then Return to the aforementioned procedure 103. In the second method disclosed above, even if the current speed value is quite different from the target speed value at the beginning, the numerical comparison and resistance control procedures (such as the loops of procedures 103, 105, 107, 108, 103... , Or the loop of programs 103, 105, 106, 110, 111, 103...), the current speed value will also approach or meet the target speed value.

From the aforementioned program 107 to the program 109 (located at the far left of the flowchart), it means that the current rotation speed of the endless belt 23 is still slower than the speed set by the user, but the rotation resistance of the endless belt 23 has reached the adjustable range The lower limit, that is to say, in principle, can no longer help to speed up the movement by reducing the resistance, at this time, the control unit 60 will control the display device 41 to display relevant information to inform the user that the movement speed may have reached the upper limit, and the control unit 60 The target speed value is appropriately modified according to the current speed value at this time, and accordingly the input devices 42, 43, and 44 are modified to allow the current user to set the upper limit of the motion speed.

Symmetrically, from the foregoing procedure 110 to the procedure 112 (located at the far right of the flowchart), it means that the current rotation speed of the endless belt 23 is still faster than the speed set by the user, but the rotation resistance of the endless belt 23 has reached the The upper limit of the adjustment range, that is to say, in principle, it is no longer possible to help slow down the movement speed by increasing resistance. At this time, the control unit 60 controls the display device 41 to display relevant information to inform the user that the movement speed may have reached the lower limit, and The control unit 60 will appropriately modify the target speed value according to the current speed value at this time, and accordingly correct the input devices 42, 43, 44 for the current user to set the lower limit of the motion speed.

The main reason for designing the aforementioned program 109 and program 112 is that different users may have different weights. In theory, if the other conditions are the same, the heavier users may drive the endless belt 23 to rotate around the upper and lower speed limits. For users who are lighter in weight and a user has just started using the aforementioned human-powered treadmill, the input devices 42, 43, and 44 will temporarily allow the user to arbitrarily set the exercise speed within a conventional range, for example, weight 100 Both users with a weight of 50 kg and a weight of 50 kg can set the exercise speed to a high speed of 16 km/h or a low speed of 0.5 km/h, but the heavier users can achieve the high speed, and even the lighter users may If the resistance is adjusted to the minimum, it cannot be achieved. On the contrary, users with lighter weight can achieve it. The low speed may not be achieved even if the user with heavier weight is adjusted to the maximum. Therefore, the aforementioned control mode uses the program 109 and the program 112 to correct the user to set the exercise speed to be higher than their upper limit and lower than their own The condition of the lower limit. The possible setting range of the moving speed is reset to the aforementioned conventional range after the endless belt 23 stops rotating.

Preferably, during the operation of the aforementioned control mode, the control unit 60 can estimate the endless belt body when the aforementioned resistance is adjusted to the lower limit (and upper limit) of the adjustable range according to the change relationship between the aforementioned resistance and the current speed value The rotation speed of 23 can be used to modify the input devices 42, 43, and 44 for the current user to set the upper limit (and lower limit) of the movement speed. In this way, the user can grasp the upper limit (and lower limit) of the movement speed that the individual may reach, and the user experience is better.

It can be seen from the above description of the flow shown in FIG. 7 that when the user walks or runs on the human-powered treadmill of this preferred embodiment operating in the aforementioned control mode, basically, the endless belt 23 rotates The resistance will be automatically reduced/increased because the current rotation speed is slower/faster than the speed set by the user, so that the speed of the endless belt 23 is accelerated/decreased under the same force, so it approaches or meets the speed set by the user . Moreover, by repeatedly comparing the current speed value with the target speed value, and controlling the increase or decrease of the resistance according to the comparison result, even if the movement speed set by the user changes during the movement, and/or the user exerts force on the endless belt 23 Changed, the rotation speed of the endless belt 23 can still keep approaching or conform to the speed set by the user.

In addition to the aforementioned control modes, the human-powered treadmill of this preferred embodiment may also operate in other modes. For example, in another control mode that is available for selection, the control unit 60 will not actively control the magnitude of the aforementioned resistance, instead, use The user can instruct the control unit 60 to adjust the aforementioned resistance through the input devices 42, 43, and 44. That is, like a conventional human-type treadmill, the user can set an appropriate resistance for walking or running, and adjust it at any time during the exercise resistance.

In the preferred embodiment disclosed above, the endless belt 23 adopts the most commonly used structure type of a general treadmill, that is, it is formed by connecting a long belt body end to end, and has a continuous endless surface with the top The flat plate 26 usually needs to be provided under the surface 24 to support the weight of the user, and the frictional force between the endless belt 23 and the flat plate 26 also becomes a resistance to the endless rotation of the endless belt 23. The endless belt of the human-powered treadmill of the present invention may also adopt a slat-belt structure in the prior art, that is, it is formed by juxtaposition and articulation of many plates extending in the left-right direction, which can directly support the user The weight, and the rotation resistance is small. If the endless belt body adopts a crawler structure, then, according to According to the design requirements, in addition to the possibility of setting the endless belt body to a shape where the top surface forms an inclined surface, it is also possible to arrange the endless belt body to a shape that the top surface presents a concave arc shape. For example, FIG. 8 shows a modification of the preferred embodiment disclosed above (note: the schematic manner and representative symbols of FIG. 6 are used), wherein the endless belt 23 is a crawler structure, and the endless belt The top surface 24 of 23 has a concave arc shape, the middle part of which is lower than the front and rear ends. The user U in motion usually steps on a main force zone 25 between the front end of the top surface 24 and the middle part. The area 25 also appears to extend from the upper front to the lower back, which is beneficial to the user U exerting a force from the front to the back on the top surface 24 of the endless belt 23. When the user walks or runs on such a human-powered treadmill with a concave arc shape on the sports surface (ie, the aforementioned top surface 24), if the forward stepped foot is stepped in front of the main force receiving area 25 / The more rearward, the greater/smaller the force applied to the top surface 24 after the foot slides down, the force applied to the endless belt 23 is not easy to maintain stability, but by the lifting control mechanism of the present invention, The movement speed can keep approaching or conform to the set speed, and will not change significantly due to the change of the user's force.

Next, please refer to FIG. 9, which is a schematic diagram of the structure of the human-powered treadmill according to the second preferred embodiment of the present invention (Note: the schematic manner and representative symbols in FIG. 6 are basically used), compared with the manpower shown in FIGS. 6 and 8 Type treadmill, the structural characteristics of the human-powered treadmill of the preferred embodiment mainly include: the frame body includes a fixed frame 16 supported on the ground and a movable frame 17 that can change position relative to the fixed frame 16, in this example In the middle, the rear end of the movable frame 17 is pivotally connected to the fixed frame 16 according to the left and right axial directions, so that the movable frame 17 can be deflected up and down with respect to the fixed frame 16 and the ground with its rear end as the axis; the endless belt 23 can rotate cyclically The front end of the top surface 24 of the movable frame 17 is higher than the rear end. When the movable frame 17 deflects up and down with its rear end as the axis, the elevation angle of the front end of the top surface 24 of the endless belt 23 relative to the rear end is also Will change accordingly; an elevation angle adjustment device 90, located between the fixed frame 16 and the movable frame 18, has a motor (not labeled) that can drive the movable frame 17 to change its position relative to the fixed frame 16, in this case That is, the movable frame 17 is driven to deflect up and down within a predetermined angle range with its rear end as the axis; the control unit 60 can use a second control signal to control the elevation angle adjustment device 90 to drive the movable frame 17 to deflect, which is equal to control to increase or decrease the endless belt The elevation angle of the top surface 24 of the body 23.

The fixed frame 16, the movable frame 17 and the elevation angle adjusting device 90 shown in FIG. 9 are merely schematic, and the specific structure in practice can be applied to the corresponding structures of various power treadmills that can adjust the elevation angle of the running table in the prior art. In a modification of the preferred embodiment (not shown), the endless belt 23 is only partially provided on the movable frame 17, for example, the front end of the endless belt 23 is supported by the front roller on the movable frame 17, And the last end is supported by the rear roller on the fixed frame 16, so, when the movable frame When the position of 17 relative to the fixing frame 16 changes, the elevation angle of the top surface 24 of the endless belt 23 also changes accordingly.

In addition to the above structure, the human-powered treadmill of this preferred embodiment also has a display device 41, input devices 42, 43, 44, resistance adjusting device 50, and a sensing device 80. Since the structure and function of each device are basically the same as the front The corresponding devices in a preferred embodiment are the same, so they will not be described again.

10A and 10B, the endless belt 23 in the schematic diagram 9 is subjected to the same downward force DF at the first elevation angle θ 1 and the second elevation angle θ 2, respectively, that is, as shown in FIG. 10A, when the loop When the elevation angle of the top surface 24 of the belt 23 is a relatively small first elevation angle θ 1, the downward force DF of the user's weight in the direction of movement of the top surface 24 of the endless belt 23 (first component ) CF1 is also relatively small; relatively, as shown in FIG. 10B, when the elevation angle of the top surface 24 of the endless belt 23 is a relatively large second elevation angle θ2, the same downward force DF is on the endless belt 23 The component (second component) CF2 of the top surface 24 in the direction of motion is also relatively large (note: the downward force DF perpendicular to the ground, the vertical line V perpendicular to the top surface 24, and the parallel The first component force CF1/the second component force CF2 on the aforementioned top surface 24 together form a right triangle). To put it simply, if other conditions are the same, the larger/smaller the elevation angle of the top surface 24 of the endless belt 23 is, the greater/smaller the force that the user exerts on the top surface 24 from front to back is The speed at which the ribbon 23 is forced to rotate will also be faster/slower.

Although the endless belt 23 in FIGS. 9, 10A, and 10B is a type in which the top surface 24 forms a slope, the endless belt 23 having a concave arc shape as shown in FIG. 8 can also be applied to In this preferred embodiment, the important point is that regardless of whether the top surface 24 of the endless belt 23 forms an inclined surface or a concave arc surface, when the endless belt 23 moves in whole or in part with the movable frame 17, the main surface of the top surface 24 The elevation angle of the front end of the force zone relative to the rear end will also change, and the larger/smaller the aforementioned elevation angle, the greater/smaller the user's force to drive the endless belt 23 to rotate.

FIG. 11 shows the basic flow of a control mode of the preferred embodiment. In simple terms, in this control mode, the control unit 60 repeatedly compares the current speed value and the target speed value that are likely to change. Whenever the current speed value When it is below/above the target speed value and the aforementioned resistance has not reached the lower limit/upper limit of the adjustable range, the resistance adjustment device 50 is controlled to reduce/increase the resistance, and furthermore, when the current speed value is below/above the target speed value and the aforementioned resistance When the lower limit/upper limit of the adjustable range has been reached, the aforementioned elevation angle adjusting device 90 is controlled to increase/decrease the aforementioned elevation angle if possible. Fig Many of the programs in 11 are substantially the same as the corresponding programs in the control mode of the previous preferred embodiment shown in FIG. 7 (Note: Specifically, programs 201 to 208 and programs 212 and 213 in FIG. 11 correspond to the The procedures 101 to 108 and procedures 110 and 111 in 7), except for a few differences, will be specifically explained in the following text, and the same parts will not be repeated.

From program 207 to program 209, it means that the current rotation speed of the endless belt 23 is slower than the speed set by the user, and the rotation resistance of the endless belt 23 has reached the lower limit of the adjustable range, the control unit 60 will further determine the endless If the aforementioned elevation angle of the belt body 23 has reached the upper limit of the adjustable range, if yes, proceed to procedure 211; otherwise, proceed to procedure 210. In the procedure 210, the control unit 60 controls the elevation angle adjustment device 90 to increase the aforementioned elevation angle, and then, the flow returns to the procedure 203 to re-determine whether there is a need to change the target speed value.

Symmetrically, from program 212 to program 214, it means that the current rotation speed of the endless belt 23 is faster than the speed set by the user, and the rotation resistance of the endless belt 23 has reached the upper limit of the adjustable range, the control unit 60 will further It is determined whether the aforementioned elevation angle of the endless belt 23 has reached the lower limit of the adjustable range, and if so, proceed to procedure 215; otherwise, proceed to procedure 216. In the program 215, the control unit 60 controls the elevation angle adjusting device 90 to reduce the aforementioned elevation angle, and then, the flow returns to the program 203 to re-determine whether there is a need to change the target speed value.

In detail, the control unit 60 controls the increase of the elevation angle in the aforementioned procedure 210, and the control of the aforementioned elevation angle in the aforementioned procedure 215. There are two different methods of implementation. The first method is that the control unit 60 will perform the procedure 210/ The program 215 continuously controls the increase/decrease of the aforementioned elevation angle, so that the endless belt 23 increases/decreases the rotation speed due to the user's aforementioned increase/decrease of the component force until the current speed value is equal to the target speed value (or The difference between the two is within a predetermined degree), or the aforementioned elevation angle has reached the upper or lower limit of the adjustable range before entering the next procedure, that is, returning to the procedure 203; the second method is that the control unit 60 In program 210/program 215, only the above-mentioned elevation angle is controlled to increase/decrease by a predetermined degree at a time, and it is usually adjusted in small steps, for example, by changing the above-mentioned elevation angle by 0.5 degrees, and then returns to program 203.

From the foregoing program 209 to program 211, it means that the current rotation speed of the endless belt 23 is still slower than the speed set by the user, but the rotation resistance of the endless belt 23 has reached the lower limit of the adjustable range, and the endless belt The aforementioned elevation angle of 23 has also reached the upper limit of the adjustable range, that is, in principle, it is no longer possible to help speed up the movement by reducing the resistance or increasing the elevation angle. At this time, the control unit 60 controls the display device 41 to display related information Inform the user that the movement speed may be The upper limit has been reached, and the control unit 60 will appropriately modify the target speed value according to the current speed value at this time, and accordingly correct the input devices 42, 43, and 44 for the current user to set the upper limit of the movement speed.

Symmetrically, from the aforementioned program 214 to program 216, it means that the current rotation speed of the endless belt 23 is still faster than the speed set by the user, but the rotation resistance of the endless belt 23 has reached the upper limit of the adjustable range, and the ring The aforementioned elevation angle of the ribbon body 23 has also reached the lower limit of the adjustable range, that is, in principle, it is no longer possible to help slow down the movement speed by increasing the resistance or reducing the elevation angle. At this time, the control unit 60 will control the display device 41 Display relevant information to inform the user that the movement speed may have reached the lower limit, and the control unit 60 will appropriately modify the target speed value according to the current speed value at this time, and accordingly correct the input devices 42, 43, 44 for the current user to set the movement The lower limit of speed.

It must be noted that in the program 203, the control unit 60 will determine whether there is a need to change the target speed value, and whether the newly received input from the input device 42, 43, 44 containing the setting of the above-mentioned elevation angle Instruction signal, if the control unit 60 receives an instruction signal containing the aforementioned elevation angle, enter the program 204 first, the control unit 60 will control the elevation angle adjustment device 90 so that the aforementioned elevation angle conforms to the user's instruction, and then enter the program 205; if neither If it is necessary to change the target speed value and no instruction signal containing the aforementioned elevation angle is received, the program 205 is directly entered.

Preferably, during the operation of the control mode, the control unit 60 can estimate the resistance when the resistance is adjusted to the lower limit of the adjustable range and the elevation angle is adjusted to be adjustable based on the change relationship between the resistance, the elevation angle and the current speed value. The rotation speed of the endless belt 23 at the upper limit of the range (and the rotation speed of the endless belt 23 when the resistance is adjusted to the upper limit of the adjustable range and the elevation angle is adjusted to the lower limit of the adjustable range), according to The correction input devices 42, 43, and 44 allow the current user to set the upper limit (and lower limit) of the movement speed. In this way, the user can grasp the upper limit (and lower limit) of the movement speed that the individual may reach, and the user experience is better.

It can be known from the above description of the flow shown in FIG. 11 that when the user walks or runs on the human-powered treadmill of this preferred embodiment operating in the aforementioned control mode, the user can set the aforementioned elevation angle and movement speed at any time (Including separate settings and combined settings), basically, by repeatedly comparing the current speed value with the target speed value, and controlling the increase or decrease of the resistance according to the comparison result, even if the aforementioned elevation angle or movement speed set by the user changes during the movement, and /Or the force applied by the user to the endless belt 23 changes, and the rotation speed of the endless belt 23 can still be kept close to or in accordance with the use The speed set by the user; although in this control mode that meets the user's instruction on the speed of movement, if necessary, the increase and decrease of the elevation angle will be controlled according to the comparison result, but the speed set by the user cannot be reached unless the elevation angle is changed. Otherwise, the aforementioned elevation angle will not change automatically. That is to say, according to this control mode, the user can walk or run at the set exercise speed substantially at the set elevation angle.

In addition to the aforementioned control modes, the human-powered treadmill according to the preferred embodiment may also operate in other modes. For example, in an alternative control mode, the control unit 60 neither actively controls the aforementioned elevation angle nor Will actively control the magnitude of the aforementioned resistance, instead, the user may instruct the control unit 60 to adjust the aforementioned elevation angle and the aforementioned resistance through the input devices 42, 43, 44; that is, the user may maintain the aforementioned elevation angle and the established resistance Walk or run down, and can adjust the elevation angle and resistance at any time during the exercise.

In another alternative control mode, the user can only set the movement speed, but cannot set the aforementioned elevation angle or the aforementioned resistance, that is, the control unit 60 fully aims to achieve the movement speed set by the user, and automatically controls the aforementioned resistance and the aforementioned Make necessary adjustments to the elevation angle, including adjusting only one of the resistance and the elevation angle at the same time (or the same processing procedure), and adjusting both the elevation angle and the resistance at the same time (or the same processing procedure), such as controlling the simultaneous reduction of resistance Increase the elevation angle, or control to increase the resistance while reducing the elevation angle.

In yet another control mode that can be selected, the input devices 41, 42, 43 allow the user to select one exercise intensity from among a plurality of exercise intensity, each exercise intensity presets an elevation angle value and a speed value; when the control unit 60 receives After the instruction signal specifying the exercise intensity is included, the elevation angle adjusting device 90 is controlled so that the elevation angle conforms to the elevation angle value preset by the exercise intensity, and the speed value preset by the exercise intensity is used as the target speed value. In this way, the user can quickly increase or decrease the overall intensity of the exercise in stages.

In order to improve the convenience of use, the human-powered treadmill of the present invention can also be designed as follows: When the control unit determines that no user is exercising on the treadmill (for example, the aforementioned speed signal is not received or obtained from the speed signal 'S current speed value is 0, and it lasts for a period of time), it will control the resistance adjustment device to generate a maximum resistance, and/or control a braking device (not shown) to generate a braking resistance. The aforementioned maximum resistance and/or the aforementioned braking resistance may allow The endless belt body can remain stationary even if it carries a user, meaning that when a user who does not exceed the expected weight stands on the endless belt body, the user's weight alone is on the top surface of the endless belt body The force component in the direction of motion is not It is enough to overcome the rotation resistance of the endless belt; then, when the control unit receives an instruction signal from the input device containing the instruction to start the movement, it will control the display device to display a message to prompt the user to start the movement, and control The resistance of the resistance adjusting device and/or the braking device decreases after a predetermined time to the extent that the endless belt body can start to rotate cyclically because it carries a user. Among them, the structure of the braking device and the control of the braking resistance may be the same as one of the various resistance adjusting devices disclosed above. The user instructs to start the exercise through the input device, which may be by pressing a physical or virtual button such as "START" or "GO" to give the instruction, or when the user completes the input to set the exercise speed or exercise program During operation (Note: Usually you need to press the "Confirm" or "OK" button at the end), that is, as the instruction to start the exercise.
