Abstract
Description
Technical Field
[0001] The invention relates to the field of fitness equipment, in particular to a treadmill multifunctional training device. Background Art
[0002] Both treadmills and bird trainers are commonly used fitness equipment, and both occupy a large volume. Treadmills are more widely used than bird trainers. The treadmill is the core component of the treadmill. The structure of the treadmill can refer to a treadmill belt structure disclosed in a Chinese patent with announcement number CN210495052U, which includes a front roller, a rear roller and a running belt. The running belt is tensioned on the front roller and the rear roller. The rotation of the front roller is controlled by a motor. The front roller and the motor shaft are provided with pulleys. The belt moves synchronously. When the motor rotates, it can drive the front roller to rotate, and finally drive the running belt and the rear roller to rotate.
[0003] The flying bird trainer is also known as the "gantry", "tension trainer", "double-arm cross trainer", etc. It mainly consists of two pull rings, multiple pulley groups and damping. The pull ring is connected to the damping after being wrapped around the pulley group by the first pull rope. There are generally two ways to set the damping. One is to use a counterweight to counteract the tension, and some use the reverse torque of the motor to counteract the tension. The method of using the counterweight requires manual replacement of the counterweight and the counterweight occupies a certain external space; while the method of using the reverse torque of the motor to counteract can change the size of the motor torque according to the program control of the controller to adjust, which is easy to operate and does not occupy external space.
[0004] The structure that utilizes the torque of the motor to counteract the pulling force can refer to a damping adjustable leg trainer disclosed in Chinese patent publication number CN214913017U. The patent discloses a damping component, which includes a motor, a sliding rheostat and a controller. The resistance value of the sliding rheostat is controlled by a program of the controller to adjust the resistance.
[0005] The existing flying bird trainers and treadmills can only realize a single function. For families with the above two training needs, the purchase cost will be significantly increased, and the space occupied by both will be large after being purchased at the same time. Summary of the invention
[0006] Aiming at the shortcomings of existing flying bird trainers and treadmills that can only realize a single fitness function and occupy a large volume after purchase, the present invention provides a running flying bird multifunctional trainer that can simultaneously realize the dual training functions of running and pulling resistance.
[0007] In order to solve the above technical problems, the present invention is solved by the following technical solutions:
[0008] A multifunctional training device for running and flying birds comprises a treadmill, which comprises a frame, columns arranged on both sides of the frame and a running belt arranged on the frame, wherein the rotation of the running belt is controlled by a motor, and a flying bird trainer is arranged between the columns, wherein the flying bird trainer comprises a first pull rope, an output component connected to a human body at one end of the first pull rope, and a first reel at the other end of the first pull rope with part of the first pull rope wound up, wherein a damping mechanism for increasing the release resistance of the first pull rope is arranged between the first reel and the frame, wherein the damping mechanism comprises a motor for synchronously providing power for the running belt and a clutch switching component for driving the first reel to clutch the motor, and wherein a reset mechanism for driving the first reel to automatically wind up the first pull rope is arranged between the first reel and the frame.
[0009] By adopting the above scheme, the flying bird trainer is integrated into the column of the treadmill. The two relatively independently arranged training equipment can significantly reduce the floor space. The damping of the flying bird trainer adopts motor damping. The resistance that drives the output component to move can be adjusted by adjusting the output resistance of the motor. The rotation speed of the running belt of the treadmill is realized by the rotation speed of the motor. The output resistance of the flying bird trainer and the power output of the treadmill of this scheme are controlled by the same motor. Through a clutch switching component that reciprocates along the axial direction of the motor shaft, the first reel connected to the output component and the first motor are engaged or disengaged, and the synchronous rotation with the first motor when engaged is realized. When the first reel is engaged with the motor, it switches to the strength training mode. At this time, the endurance training of the treadmill is in a restricted state, and the motor provides The first reel has a resistance in the opposite direction to the direction of releasing the pull rope. The exerciser needs to apply a certain force to the output component to overcome the resistance of the motor to release the pull rope wound in the first reel, thereby achieving strength training; when the first reel is separated from the motor, it can be switched to the endurance exercise mode of the treadmill. At this time, the strength training of the bird trainer is in a restricted state. When the output component is pulled, there is only a small resistance carried by the reset mechanism. The rotation of the motor drives the running belt to rotate, and the speed of the running belt is changed by adjusting the speed of the motor. Compared with setting two motors that can adjust the speed or resistance respectively, only one motor and a retractable drive mechanism are required, and the volume occupied is smaller, which can be integrated and built into the base, further improving the compactness of the overall structure. At the same time, it can also reduce the setting cost.
[0010] Preferably, the clutch switching component includes a fixed engaging part fixed to the end of the motor shaft, a movable engaging part fixed on the first reel, a fixed shaft arranged concentrically with the first reel and the movable engaging part, and a driving mechanism for driving the fixed shaft to move axially back and forth to enable the movable engaging part to approach and engage with the fixed engaging part or move away from the fixed engaging part.
[0011] By adopting the above scheme, the driving mechanism drives the axial movement of the fixed shaft to realize the engagement or disengagement of the movable engagement member and the fixed engagement member. When the two are engaged, it switches to the strength training mode; when the two are disengaged, it switches to the running training mode.
[0012] Preferably, the driving mechanism includes a toggling component that can toggle the fixed shaft and drive the movable engaging member to disengage from the fixed engaging member, and a resetting component that drives the movable engaging member to automatically engage with the fixed engaging member when the fixed shaft loses the toggling force of the toggling component.
[0013] By adopting the above scheme, the function of the toggle mechanism is to achieve the disengagement of the movable bite part and the fixed bite part, so that the motor only drives the running belt of the treadmill to rotate; the function of the reset part is to drive the movable bite part to automatically engage with the fixed bite part, so that the motor provides resistance when the output part of the flying bird trainer is pulled outward.
[0014] Preferably, the toggle component includes a fixing member vertically arranged on the fixed shaft, a telescopic driving member fixedly arranged on the frame, and a toggle member fixed to the telescopic end of the telescopic driving member. When the telescopic driving member contracts, the toggle member abuts against and drives the fixed member to move synchronously; when the telescopic driving member extends, the fixed member is reset, the toggle member is located between the fixed member and the first reel, and the distance between the toggle member and the fixed shaft is matched.
[0015] By adopting the above scheme, the telescopic driving member can realize telescopic movement. When it is in the retracted state, its push piece moves to abut against the fixed member and presses the fixed member to move in the direction away from the motor, thereby realizing the disengagement of the mobile bite member and the fixed bite member; when the telescopic driving member is in the extended state, the fixed shaft is reset under the action of the first elastic member, the mobile bite member is engaged with the fixed bite member, and the push piece is located between the fixed member and the mobile bite member. When the first reel rotates synchronously with the motor shaft, the push piece will never contact the fixed shaft, the fixed member and the first reel, and will not interfere with the rotation of the fixed shaft.
[0016] Preferably, the telescopic driving member is a cylinder or an electric push rod.
[0017] By adopting the above solution, both the cylinder and the electric push rod can realize telescopic movement.
[0018] Preferably, the telescopic driving member is symmetrically arranged in two groups with the fixed axis as the center, and the shifting member includes a shifting rod fixed to the telescopic end of the telescopic driving member and a shifting ring fixed to the two shifting rods at both ends. The inner diameter of the shifting ring is larger than the rotating shaft and abuts against the fixed member when it is away from the first reel.
[0019] By adopting the above scheme, after the telescopic driving components are symmetrically arranged in two groups with the fixed axis as the center, the movement of the toggle ring is smoother, and it can drive the fixed axis to move axially to avoid jamming during movement. The fixed seat is used to fix the two telescopic driving components and realize the clearance fit between the toggle ring connected to the telescopic driving components and the machine base, so as to realize stable movement of the toggle ring.
[0020] Preferably, an extension shaft with a diameter smaller than the fixed shaft is extended from one end of the fixed shaft away from the first reel, and a fixed seat is fixed on the frame. The first elastic member is a first elastic member which is sleeved on the extension shaft and elastically abuts against the fixed seat and the fixed shaft at both ends respectively.
[0021] By adopting the above solution, the setting of the fixing seat can not only fix the telescopic driving member, but also facilitate the installation of the first elastic member.
[0022] Preferably, one end of the fixed shaft away from the first reel is passed through the fixed seat, and a matching structure that allows the fixed shaft to rotate smoothly and move axially smoothly is provided on the fixed seat.
[0023] By adopting the above solution, through the matching structure, the fixed shaft can also achieve smooth rotational movement after axial movement.
[0024] Preferably, the matching structure includes a rotating bearing arranged on the fixed seat, an axially recessed slide groove on the fixed shaft, and a sliding key sliding in the slide groove, and a groove is recessed on the inner ring of the rotating bearing for the sliding key to be partially inserted by interference fit.
[0025] By adopting the above scheme, the sliding key is fixed to the inner ring of the rotating bearing through the slot. Therefore, when the fixed shaft undergoes axial displacement relative to the rotating shaft, the sliding key slides smoothly in the slot. When the fixed shaft rotates, the sliding key can ensure that the fixed shaft always rotates synchronously with the inner ring of the rotating bearing.
[0026] Preferably, the matching structure is provided between the fixed seat and the extension shaft, the first elastic member is sleeved on the extension shaft and two ends of the first elastic member are respectively elastically in contact with the fixed shaft and an inner ring of a rotating bearing away from the fixed shaft.
[0027] By adopting the above scheme, after providing matching structures between the fixed seat and the extension shaft and between the fixed seat and the fixed shaft, one end of the first elastic member elastically abuts against the fixed shaft and the other end elastically abuts against the inner ring of the rotating bearing. The advantage of such a setting is that when the fixed shaft rotates, the first elastic member rotates synchronously, and the first elastic member will not wear against the fixed seat or the fixed shaft, and the first elastic member will not interfere with the smooth rotation of the fixed shaft.
[0028] Preferably, a first protection mechanism for reducing the axial load of the rotating bearing abutted by the first elastic member is provided on the fixed seat, and the first protection mechanism includes a first thrust ball bearing provided on the fixed seat and rotating concentrically with the fixed shaft, and one side rotating surface of the first thrust ball bearing fits with the inner ring of the rotating bearing abutted by the first elastic member.
[0029] With the above solution, when the first elastic member abuts against the inner ring of the rotating bearing, the inner ring is subjected to an axial load, the direction of which is perpendicular to its movement direction. Over time, the rotating bearing will be damaged, resulting in a reduction in its service life, and a first thrust ball bearing is added.
[0030] Preferably, a limiting mechanism for limiting excessive advancement of the axially fixed engaging member is provided on the fixing seat, and the limiting mechanism comprises a limiting block provided at one end of the extending shaft away from the fixing shaft.
[0031] With the above solution, once the fixed shaft is excessively advanced, the motor shaft will be subjected to a large axial load, which will reduce the service life of the motor.
[0032] Preferably, a second protection mechanism is provided between the limit block and the fixed seat to reduce the degree of friction between the limit block and the fixed seat when the fixed shaft rotates. The second protection mechanism includes a second thrust ball bearing provided on the fixed seat and rotating synchronously with the extension shaft. When the first elastic member is in a reset state, the limit block fits closely with the rotating surface of the second thrust ball bearing.
[0033] By adopting the above solution, the second thrust ball bearing can offset the axial load caused by the limit block and ensure that the limit block can rotate smoothly and synchronously with the extension shaft.
[0034] Preferably, the reset mechanism includes a second reel and an elastic rope coaxially fixed on the fixed axis, one end of the elastic rope is fixed to the second reel, and the other end of the elastic rope is fixed to the bottom of the frame, and when the first pull rope in the first reel is in a released state, the elastic rope is in a stretched state.
[0035] By adopting the above scheme, when the first pull rope is released, the exerciser has driven the output part to overcome the damping to exercise. Therefore, the elastic rope is in a stretched state. Only when the output part is released, the part of the elastic rope drives the second reel to reverse, causing the first reel to reverse synchronously and rewind the first pull rope again.
[0036] Preferably, the rotation of the treadbelt is controlled by the rotation of the rotating roller that tensions it, and the motor shaft passes through both ends of the motor. A synchronous belt assembly is arranged between the end of the motor shaft close to the end of the rotating roller and the rotating roller, and the fixed bite piece is coaxially fixed to the end of the motor shaft away from the synchronous belt assembly.
[0037] With the above solution, the motor shaft passes through both ends of the motor, one end of the motor shaft is connected to the rotating roller through a synchronous belt, and the other end of the motor shaft is engaged with the clutch switching component. This arrangement can improve space utilization and make the structure more compact.
[0038] Preferably, the fixed engaging member and the movable engaging member are respectively provided with convex teeth and tooth-shaped grooves for the convex teeth to be inserted at opposite ends.
[0039] By adopting the above scheme, the engagement of the fixed engaging part and the movable engaging part is achieved by utilizing the cooperation between the convex teeth and the tooth-shaped grooves.
[0040] Preferably, the convex teeth and the tooth-shaped grooves are evenly spaced and distributed circumferentially with the motor shaft as the center.
[0041] The above scheme can increase the firmness and stability of the occlusion.
[0042] Preferably, a connecting rod is fixed between the columns, and a mounting rod is vertically fixed on the connecting rod. The flying bird trainer is arranged on the mounting rod. The flying bird trainer includes a movable pulley, which rotates on a movable frame. The end of the first pull rope away from the first reel is fixedly connected to the lower end of the movable frame, and a second pull rope is wound around the movable pulley. Two groups of output pulley groups are arranged above the movable pulley on the mounting rod, and each group of output pulley groups includes two vertically spaced output fixed pulleys. Two redirecting fixed pulleys are arranged on both sides of the upper end of the mounting rod. The two ends of the second pull rope are wound around the redirecting fixed pulley and pass through the two output fixed pulleys and the ends are connected to the output component. A tensioning wheel for tensioning the second pull rope is arranged at the lower end of the mounting rod.
[0043] By adopting the above scheme, the tensioning of the tensioning wheel drives the two output components to be trained synchronously or individually. When the output component is pulled outward, the second pull rope is always in a tensioned state, the movable pulley is pulled and moves upward, and the movement of the movable pulley drives the first pull rope in the first reel to be released.
[0044] Preferably, the output pulley block is fixed on a sliding sleeve, and the sliding sleeve is mounted on a mounting rod. A limiting mechanism for limiting the sliding movement of the sliding sleeve is arranged between the mounting rod and the sliding sleeve. The limiting mechanism includes limiting holes arranged at longitudinal intervals on the mounting rod and an elastic pin assembly elastically and telescopically arranged on the sliding sleeve that can be inserted into or detached from the limiting holes.
[0045] By adopting the above scheme, the vertical height of the output pulley block can be adjusted by pulling the elastic latch assembly, thereby meeting the strength training requirements of different parts of the arms, abdomen and legs.
[0046] Preferably, a mark indicating the limit hole is provided on the mounting rod near the limit hole, and an observation window is provided on the sliding sleeve through which the mark can be exposed when the sliding sleeve is in a locked state.
[0047] By adopting the above solution, the installation height can be quickly confirmed through the marking and locked through the elastic latch assembly, thereby improving the adjustment efficiency.
[0048] Preferably, the output component is a pull ring or a binding strap.
[0049] By adopting the above scheme, the bodybuilder can directly pull the pull ring to perform strength training, or can tie the straps around the legs or arms to perform strength training.
[0050] The present invention has significant technical effects due to the adoption of the above technical scheme: the flying bird trainer is integrated into the column of the treadmill, and the two relatively independently arranged training equipment can significantly reduce the floor space occupied; the damping of the flying bird trainer adopts motor damping, and the resistance for driving the output component to move can be adjusted by adjusting the output resistance of the motor; the rotation speed of the running belt of the treadmill is realized by the rotation speed of the motor; the output resistance of the flying bird trainer of this scheme and the power output of the treadmill are both controlled by the same motor; a clutch switching component reciprocates along the axial direction of the motor shaft to realize the engagement or disengagement of the first reel connected to the output component and the first motor, and the synchronous rotation with the first motor when engaged; when the first reel engages with the motor, it switches to the strength training mode, at which time, the endurance training of the treadmill is in In the restricted state, the motor provides the first reel with a resistance in the opposite direction of releasing the pull rope. The exerciser needs to apply a certain force to the output component to overcome the resistance of the motor to release the pull rope wound in the first reel, thereby achieving strength training; when the first reel is separated from the motor, it can be switched to the endurance exercise mode of the treadmill. At this time, the strength training of the bird trainer is in a restricted state. When the output component is pulled, there is only a small resistance carried by the reset mechanism. The rotation of the motor drives the running belt to rotate, and the speed of the running belt is changed by adjusting the speed of the motor. Compared with setting two motors that can adjust the speed or resistance respectively, only one motor and a retractable drive mechanism are required, and the volume occupied by the setting is smaller, which can be integrated and built into the base, further improving the compactness of the overall structure. At the same time, it can also reduce the setting cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] Combination Figure 4-Figure 7As shown, the toggle component includes a fixing member 25 vertically arranged on a fixed shaft 26, a telescopic driving member fixedly arranged on the frame 1, and a toggle member fixed to the telescopic end of the telescopic driving member. A mounting hole is recessed in the outer wall of the fixed shaft 26, and the fixing member 25 is partially inserted in the mounting hole with interference fit. The telescopic driving member is a cylinder or an electric push rod 22. The electric push rod 22 is adopted in this embodiment. The toggle member includes a toggle rod 23 fixed to the telescopic end of the electric push rod 22 and a toggle ring 24 fixed to the two toggle rods 23 at both ends. The inner diameter of the toggle ring 24 is larger than the rotating shaft and abuts and cooperates with the fixing member 25 when it is away from the first reel 8. When the electric push rod 22 contracts, the toggle member abuts and drives the fixing member 25 to move synchronously; when the electric push rod 22 is extended, the fixing member 25 is reset, the toggle member is located between the fixing member 25 and the first reel 8, and the distance between the toggle member and the fixed shaft 26 is matched.

The fixed part of the electric push rod 22 is fixed in the fixed seat 21 by bolts. The shifting member includes a shifting rod 23 fixed to the telescopic end of the telescopic driving member and a shifting ring 24 fixed to the two shifting rods 23 at both ends. The inner diameter of the shifting ring 24 is larger than the rotating shaft and abuts against the fixing member 25 when it is away from the first reel 8.
[0074] The reset component includes a first elastic member 31, and an extension shaft 30 with a diameter smaller than the fixed shaft 26 is extended from one end of the fixed shaft 26 away from the first reel 8. A fixed seat 21 is fixed on the frame 1. The first elastic member 31 is sleeved on the extension shaft 30 and its two ends are elastically abutted against the fixed seat 21 and the fixed shaft 26 respectively.
[0075] In order to prevent the first elastic member 31 from interfering with the rotation of the fixed shaft 26, a matching structure is provided on the fixed seat 21 to allow the fixed shaft 26 and the extension shaft 30 to rotate smoothly and move axially smoothly. Figure 7-Figure 8 As shown, the matching structure includes a rotating bearing 32 arranged on the fixed seat 21, an axially recessed groove 36 on the fixed shaft 26, and a sliding key 37 sliding in the groove 36. A groove 35 is recessed on the inner ring of the rotating bearing 32 for the sliding key 37 to be partially inserted with interference fit. The same matching structure is provided between the extension shaft 30 and the fixed seat 21. The first elastic member is sleeved on the extension shaft 30 and its two ends are elastically abutted against the fixed shaft 26 and the inner ring of the rotating bearing 32 away from the fixed shaft 26 respectively. When the fixed shaft 26 and the extension shaft 30 rotate, since the first elastic member abuts against the inner ring of the rotating bearing 32, the first elastic member 31 will not interfere with the rotation of the inner ring.
[0076] In the above structure, although the first elastic member 31 does not interfere with the rotation of the inner ring of the rotating bearing 32, it will give the inner ring of the rotating bearing 32 an axial load. In order to offset the axial load and extend the service life of the rotating bearing 32, a first protection mechanism that reduces the axial load of the rotating bearing 32 abutted by the first elastic member is provided on the fixed seat 21. Figure 6-Figure 7 As shown, the first protection mechanism includes a first thrust ball bearing 33 which is arranged on the fixed seat 21 and rotates concentrically with the fixed shaft 26. One side rotating surface of the first thrust ball bearing 33 fits tightly with the inner ring of the rotating bearing 32 which is abutted by the first elastic member. The rotation of the plane bearing can offset the axial load of the inner ring, while ensuring the smooth rotation of the fixed shaft 26 and the movable shaft.
[0077] A limiting mechanism is provided on the fixed seat 21 to limit the excessive advancement of the fixed shaft 26 toward the fixed bite piece 40. The limiting mechanism includes a limiting block 29 provided at one end of the extension shaft 30 away from the fixed shaft 26. The limiting block 29 of this embodiment is a limiting screw. A threaded hole matching the limiting screw is provided at the end of the extension shaft 30 away from the fixed shaft 26. A limiting gasket 291 for increasing the radial dimension of the limiting mechanism is sleeved on the limiting screw. When the fixed shaft 26 runs toward the direction of the motor 18, the limiting gasket 291 elastically abuts against the mounting seat.
[0078] In order to avoid the friction between the limit washer 291 and the mounting seat causing the fixed shaft 26 to rotate poorly, a second protection mechanism is provided between the limit block 29 and the fixing seat 21 to reduce the degree of friction between the limit block 29 and the fixing seat 21 when the fixed shaft 26 rotates. The second protection mechanism includes a second thrust ball bearing 34 which is arranged on the fixing seat 21 and rotates synchronously with the extension shaft 30. When the first elastic member 31 is in the reset state, the limit block 29 fits with the rotating surface of the second thrust ball bearing 34. The second thrust ball bearing 34 can avoid the limit washer 291 from directly contacting the fixing seat 21. The second thrust ball bearing 34 can also ensure the smooth rotation of the fixed shaft 26 and the extension shaft 30.
[0079] A reset mechanism is provided between the first reel 8 and the frame 1 to drive the first reel 8 to release the first pull rope 16 and automatically reel the first pull rope 16. Figure 2-Figure 3 As shown, the reset mechanism includes a second reel 9 and an elastic rope 10 coaxially fixed on the fixed shaft 26, one end of the elastic rope 10 is fixed to the second reel 9, and the other end of the elastic rope 10 is fixed to the bottom of the frame 1. A reversing wheel 11 for changing the direction of the elastic rope 10 is provided at the end of the frame 1. The end of the elastic rope 10 away from the second reel 9 is fixed to the end of the frame 1 away from the column 3. When the first pull rope 16 in the first reel 8 is in a released state, the elastic rope 10 is in a stretched state.
[0080] A sensor bracket 42 is fixed to the motor 18, see Fig. 9 As shown, a rotation speed sensor 43 for detecting the rotation speed of the motor 18 and a displacement sensor 44 for detecting whether the movable engaging member 27 is engaged with the fixed engaging member 40 are arranged on the sensor bracket 42 .
[0081] A trainer instrument panel 39 is fixed to the top of the mounting rod 5, a central control instrument panel is fixed to the upper end of the column 3, and the motor 18, the electric push rod 22, the speed sensor 43 and the displacement sensor 44 are all connected to the controller.
[0082] In the running mode, the displacement sensor 44 first senses the position of the mobile bite member 27. If the mobile bite member 27 is in a state of being engaged with the fixed bite member 40, the displacement sensor 44 will send a signal to the controller. The controller first controls the electric push rod 22 to retract, and uses the dial to move the fixed member 25 away from the motor 18 until the mobile bite member 27 is disengaged from the fixed bite member 40. Subsequently, the speed of the motor 18 and other modes can be set in the central control instrument panel to drive the running belt 2 to rotate quickly. The speed sensor 43 can detect the speed of the running belt 2 in real time to ensure the accurate operation of the treadmill.
[0083] In the strength training mode, the displacement sensor 44 first senses the position of the moving bite member 27. If the moving bite member 27 is in a state of being separated from the fixed member 25, the displacement sensor 44 will send a signal to the controller. The controller first controls the electric push rod 22 to extend, and the fixed shaft 26 moves toward the motor 18 under the resetting action of the first elastic member 31 until the moving bite member 27 is engaged with the fixed bite member 40. At this time, the dial is located between the fixed member 25 and the moving bite member 27 and is clearance-matched with the fixed shaft 26, thereby avoiding interference of the dial with the rotation of the fixed shaft 26. Subsequently, the damping of the motor 18 can be adjusted in the trainer instrument panel 39. When the pull ring 50 is pulled outward, different degrees of strength training can be experienced according to the damping size.
