Example 1

As shown in fig. 1, the present embodiment provides a rotary load adjusting mechanism 100, which includes a center shaft 110, a rotation shaft 120, a load adjusting assembly 130, and a clutch assembly 140, wherein the rotation shaft 120 serves as an output member of the rotary load adjusting mechanism 100, and the output force thereon is flexibly adjusted.

The rotation shaft 120 and the middle shaft 110 form coaxial or parallel rotatable connection, and the clutch assembly 140 is disposed between the rotation shaft 120 and the middle shaft 110. When the clutch assembly 140 is engaged, the rotating shaft 120 forms a unilateral non-rotating connection with the middle shaft 110, and when the clutch assembly 140 is disengaged, the rotating shaft 120 is free to rotate bilaterally relative to the middle shaft 110. Thus, the presence or absence of the output force of the rotation shaft 120 of the rotation load adjustment mechanism 100 can be invoked by the clutch action of the clutch assembly 140.

In the above, the rotating shaft 120 can form a unilateral non-rotating connection with the middle shaft 110 through the clutch assembly 140, so that unilateral adjustment can be performed on unilateral output force of the output shaft.

The load adjusting assembly 130 is used for adjusting the rotation load of the bottom bracket 110, and the magnitude of the output force of the rotation shaft 120 can be adjusted by the load adjusting assembly 130.

In this embodiment, the load adjuster assembly 130 includes a motor 131, a brake 132, and a gear assembly 133. The brake 132 is disposed on the motor 131 and is used for adjusting the output force of the output shaft of the motor 131. The output component of the load adjusting assembly 130 is an output shaft of the motor 131, and the output force of the center shaft 110 is adjusted by adjusting the output force of the output shaft of the motor 131, when the rotating shaft 120 is engaged with the center shaft 110 through the clutch assembly 140, the output force of the center shaft 110 is an output force of one-side rotation of the rotating shaft 120.

The brake member 132 is a brake mechanism of the motor 131, and may be a disc brake, an electromagnetic band-type brake, or the like, and adjusts the output force of the output shaft of the motor 131 according to the magnitude of the input current. The output force of the output shaft of the motor 131 is the starting torque of the motor 131, which is a static torque and is related to the rated torque of the motor 131. Therefore, the output force of the output shaft of the motor 131 can be continuously adjustable through the combination of the motor 131 and the brake 132, and compared with the load adjusting assembly 130 which only adopts the motor 131 to adjust the output force, the load adjusting assembly 130 with the structure has smaller volume and wider adjustment range of the output force.

In other embodiments, the mechanism formed by the motor 131 and the brake 132 may be replaced by hydraulic or pneumatic means.

The gear pair 133 includes a plurality of transmission gears. In this embodiment, the gear pair 133 includes a first gear 133a and a second gear 133b that are meshed with each other, and the first gear 133a and the second gear 133b are spur gears. The first gear 133a is coaxially coupled to the output shaft of the motor 131, and the second gear 133b is coaxially coupled to the bottom bracket 110, whereby the output force of the output shaft of the motor 131 can be proportionally transmitted to the bottom bracket 110.

Further, the tooth diameter of the first gear 133a is smaller than the tooth diameter of the second gear 133b, whereby the second gear pair 133 acts as a kind of reduction mechanism, further increasing the torque/output force of the bottom bracket 110. The gear pair 133 plays a role in transferring force and increasing output force, so that the functional integration level is higher, and the load adjusting assembly 130 has a small volume and a large torque adjusting range.

In other embodiments, the gear pair 133 may have more gear stages, and the gear pair 133 may include types of gears such as bevel gears, worm gears, and the like, in addition to spur gears.

In this embodiment, the central shaft 110 is in a round bar shape, the rotating shaft 120 is in a shaft sleeve shape, and is rotatably sleeved on the central shaft 110, so that the central shaft 110 can rotate freely under normal conditions. The output force of the rotation shaft 120 is the rotation resistance thereof, and when the rotation shaft 120 can freely rotate, the output force of the rotation shaft 120 is the friction force between the rotation shaft and the center shaft 110. In order to reduce the abrasion between the rotating shaft 120 and the center shaft 110, a rolling bearing may be disposed between the rotating shaft 120 and the center shaft 110, wherein an inner ring of the rolling bearing is connected with the center shaft 110, and an outer ring of the rolling bearing is connected with the rotating shaft 120, so that the sliding friction between the rotating shaft 120 and the center shaft 110 can be rolling friction, and smooth relative rotation can be performed between the two.

The clutch assembly 140 includes a locking member 141 and an engaging member 142 capable of being engaged in one direction, one of the locking member 141 and the engaging member 142 is disposed on the bottom bracket 110, and the other is disposed on the rotating shaft 120, so that when the locking member 141 is engaged with the engaging member 142, a single side of the rotating shaft 120 forms a non-rotating connection with the bottom bracket 110.

In this embodiment, the locking member 141 is a ratchet, and the engaging member 142 is a ratchet card, so that a unidirectional engaging mechanism is formed, and the ratchet card and the ratchet are locked by unilateral rotation. Further, the ratchet card is connected to the bottom bracket 110, such as the end face of the second gear 133b, and the ratchet is coaxially connected to the rotation shaft 120 and sleeved on the bottom bracket 110. The ratchet card can be engaged with the ratchet by telescoping, moving, swinging, rotating, etc.

In another embodiment, as shown in fig. 2, two sets of clutch assemblies 140 are disposed between the bottom bracket 110 and the rotation shaft 120, the two sets of clutch assemblies 140 can respectively make the bottom bracket 110 and the rotation shaft 120 form a single-side non-rotation connection with opposite directions, and the rotation shaft 120 can switch the directions between the bottom bracket 110 and the rotation shaft 120 due to the engagement of different clutch assemblies 140 and the bottom bracket 110, i.e. switch the directions of the output forces of the rotation shaft 120.

The end face of the second gear 133b is provided with two ratchet cards, the rotating shaft 120 is coaxially provided with two ratchets with different ratchet orientations, and the diameter of the ratchet close to the second gear 133b is smaller, so that the two ratchet cards can be respectively clamped with the two ratchets without mutual influence.

In yet another embodiment, as shown in fig. 3, the locking member 141 is a one-way bearing, and the engaging member 142 is an engaging pin engaged with the one-way bearing. The inner race of one-way bearing is connected on axis 110, and axis of rotation 120 can be connected with the outer lane of one-way bearing through fastener 142, is equipped with the pinhole on the outer lane of one-way bearing, and fastener 142 is the block round pin of locating on axis of rotation 120, can insert in the aperture of locating one-way bearing through the flexible, and then makes axis of rotation 120 and axis of rotation 110 form unilateral rotation locking. At this time, if the rotational load adjusting mechanism 100 includes two clutch members 140, it includes two one-way bearings and two engagement pins, and the one-way bearing on the side close to the rotation shaft 120 has a smaller diameter.

The ratchet card may be a manual adjustment card slidably disposed on the rotation shaft 120, and the position of the ratchet card is adjusted by sliding, so that the ratchet card protrudes to engage with the ratchet. The ratchet card can also be an electric adjustment card, and the ratchet card and the ratchet are separated and combined through the electric adjustment of the extension and retraction of the ratchet card.

As described above, the rotation load of the rotation shaft 120 of the rotation load adjusting mechanism 100 can be selectively adjusted, and the rotation load thereof can be adjusted on one side, so that the rotation load adjusting mechanism can be applied to a device having a reciprocating rotation or a single-side rotation, and can provide an output force with a single side and adjustable force for the device. Because the rotating shaft 120 has a load on one side, and the load on one side is no load, that is, the center shaft 110 does not need to rotate reciprocally due to the one-side clutch action of the clutch assembly 140, and the load adjusting assembly 130 only needs to provide a single-side output force.

Example 2

The present embodiment provides an exercise apparatus comprising an exercise execution member connected to a rotation shaft 120, and the rotational load adjustment mechanism 100 of embodiment 1.

Fig. 4 shows a schematic structure of the stepper 1000, in which only a single clutch assembly 140 is shown, but the double-sided rotation shafts 120 of the stepper 1000 are provided with symmetrical clutch assemblies 140. The exercise device is a stepper 1000, the exercise execution part is a pedal 200, and a user can achieve the effect of exercise by stepping on the pedal 200 during exercise.

The stepper 1000 further includes an elastic restoring member 300, the rotational load adjusting mechanism 100 includes two rotational shafts 120 disposed at two ends of the central shaft 110, and a clutch assembly 140 is disposed between each rotational shaft 120 and the central shaft 110. The rotating shafts 120 are respectively connected with a pedal 200, and an elastic reset piece 300 is arranged between the rotating shafts 120 and the middle shaft 110, and the elastic reset piece 300 provides an elastic reset force for the rotating shafts 120 to rotate to a preset position.

As described above, the rotation shaft 120 is connected to the pedal 200, and when the pedal 200 is stepped on, the rotation shaft 120 rotates together with the pedal, and the rotation shaft 120 provides a rotation load for the pedal 200 to be stepped on. The two pedals 200 are respectively connected to the middle shaft 110 through two rotating shafts 120, a clutch assembly 140 is respectively arranged between the two rotating shafts 120 and the middle shaft 110, the rotation of the two pedals 200 is independent, whether the load on the two pedals 200 can be independently regulated, and the pedals 200 can be set to have a load on a single side in an ascending or descending mode.

In this embodiment, a locking member 141 is disposed on the two rotation shafts 120, a locking member 142 is disposed on two end faces of the second gear 133b, the rotation shafts 120 at two ends of the central shaft 110 are all engaged with the central shaft 110 through the clutch assemblies 140, and the single-side locking directions of the two clutch assemblies 140 to the locking of the two rotation shafts 120 are the same. When the engaging member 142 engages with the locking member 141, the spindle provides a downward load to the rotating shaft 120, i.e., the pedal 200, and the upward movement is no-load. When one pedal 200 goes down, the pedal 200 drives the middle shaft 110 to rotate through the rotating shaft 120 and the clutch assembly 140, the second gear 133b drives the engaging member 142 of the other clutch assembly 140 to reversely rotate relative to the locking direction of the locking member 141 corresponding to the engaging member 142, at this time, the upper behavior of the other pedal 200 is no-load, and the pedaling habit of one pedal 200 going up and the other pedal 200 going down of the stepper 1000 can be satisfied. The two pedals 200 alternately go up and down, so that the two pedals 200 can have load during descending, the load can be adjusted through the load adjusting assembly 130, and the pedals can be unloaded during ascending, so that the stepping muscle strength can be trained in a targeted manner.

It can be understood that by controlling the clutch of the clutch assembly 140, the stepping load of the two pedals 200 can be the load of the pedal 200 with one side, and the load of the pedal 200 with the other side is no load in both the up and down directions.

It will be appreciated that clutch assembly 140 may be used with an upward locking effect on foot pedal 200 such that foot pedal 200 is loaded during the upward movement and unloaded during the downward movement, thereby enabling targeted training of the upward muscle force.

In order to facilitate the application of force to the foot, a foot strap can be arranged on the foot pedal 200, and the foot pedal 200 can be lifted up by the foot.

The elastic restoring member 300 is disposed between the rotation shaft 120 and the middle shaft 110, and the pedal 200 and the rotation shaft 120 form a non-rotating connection, and the elastic restoring member 300 is disposed between the pedal 200 and the middle shaft 110, so as to provide an elastic restoring force for the pedal 200 to rotate to a preset position. The preset position may be a position where the foot board 200 is parallel to the horizontal plane, or a position where the foot board is raised or lowered relative to the horizontal plane. The elastic restoring member 300 may be a torsion spring or a coiled spring sheet disposed between the rotation shaft 120 and the middle shaft 110.

The treadmill 1000 further includes a body 400 and a supporting member 500, the body 400 having a receiving chamber for receiving the rotational load adjusting mechanism 100, the rotational shaft 120 being exposed from the body 400 for connection with the exercise performing member.

The exercise actuator can be telescopically folded relative to the body 400. Thus, the stepper 1000 can be telescopically folded except the machine body 400 and the rotating shaft 120, and the space occupied by the stepper 1000 when being stored or transported is smaller.

In this embodiment, the machine body 400 is in a shell shape, the middle shaft 110 is rotatably disposed on the machine body 400, and in order to ensure smooth rotation of the middle shaft 110 on the machine body 400, a bearing may be disposed between the middle shaft 110 and the machine body 400. The motor 131 and the brake 132 of the load adjusting unit 130 are fixed to the body 400, the output shaft of the motor 131 can freely output force, the force of the output shaft of the motor 131 is transmitted to the spindle through the gear pair 133, a rotational load is formed on the spindle, and when the rotation shaft 120 is engaged with the spindle through the clutch unit 140, the load of the spindle is transmitted to the rotation shaft 120 to become the load of the rotation shaft 120.

The extension rule of the supporting member 500 is that the free end is contracted toward the connection end, and the end far from the body 400 is contracted toward the connection end with the body 400. The support 500 includes a plurality of square sleeves, which gradually increase from the free end to the connection end, similar to the telescopic structure of an antenna. Meanwhile, in order to ensure that the support 500 can maintain a stable form in the common sense, an elastic buckle can be arranged between the two sleeves, and the structure is similar to a telescopic locking structure of the umbrella handle of the folding umbrella, which is not repeated herein.
