The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, the exercise apparatus provided by the embodiment of the present application may include a frame 100, a force receiving mechanism 200, a reciprocating damping mechanism 300, a seat cushion 111, and a control mechanism 400.

The frame 100 can be used as a main body frame of the fitness equipment, and the force receiving mechanism 200, the reciprocating damping mechanism 300, the seat cushion 111 and the control mechanism 400 are arranged on the frame 100. The force mechanism 200 is used for pushing and pulling by a user. When the user uses the exercise apparatus, the force-receiving mechanism 200 can be rotated back and forth in a first direction and a second direction opposite to the first direction by the push and pull of the user. The reciprocating damping mechanism 300 is used for generating damping during the reciprocating rotation of the force-receiving mechanism 200 in the first direction and the second direction, so as to enable the user to exercise. The seat cushion 111 may be used for a user to sit on, so that the user can push and pull the force receiving mechanism 200 when sitting on the seat cushion 111. Control mechanism 400 may be used to adjust the amount of damping of reciprocating damping mechanism 300.

The housing 100 may be trapezoidal in shape. The concrete structure can comprise a cross beam (not marked), two longitudinal beams (not marked) and a bottom beam (not marked), wherein two ends of one longitudinal beam are respectively connected with one end of the cross beam and one end of the bottom beam, and two ends of the other longitudinal beam are respectively connected with the other end of the cross beam and the other end of the bottom beam. The cross beam and the longitudinal beam can be in arc transition at the joint of the cross beam and the longitudinal beam, and the included angle between the cross beam and the longitudinal beam can be 90-150 degrees, and can be 120-130 degrees optionally. Of course, the included angle between the cross beam and the longitudinal beam can be smaller than 90 degrees. Of course, the angle between the two longitudinal beams and the cross beam can be the same or different. The included angle between the longitudinal beams and the bottom beam can be less than 90 degrees, and can be 60-75 degrees. Through setting the frame 100 to be trapezoidal and the angle setting between crossbeam, floorbar and the longeron, can improve the structural stability of frame 100, and then can promote body-building equipment's operational reliability and life. The cross beam, the two longitudinal beams and the bottom beam of the frame 100 may enclose a space, the reciprocating damping mechanism 300 and the control mechanism 400 may be disposed in the space, and the seat cushion 111 may be located outside the space and fixed to the outside of the frame 100. The reciprocating damping mechanism 300 may be located below the seat cushion 111. The space enclosed by the frame 100 accommodates the reciprocating damping mechanism 300, the control mechanism 400 and the like, so that the volume of the body-building equipment is reduced, and the space utilization rate is improved.

The force mechanism 200 may include two push-pull levers. The two push-pull hand rods are located on two sides of the frame 100, one end of each push-pull hand rod is connected with the reciprocating damping mechanism 300, and the other end of each push-pull hand rod extends to the upper portion of the frame 100 and is located on two sides of the seat cushion 111. The user can be when sitting in cushion 111, two push-and-pull handspikes of both hands operation to two push-and-pull handspikes of push-and-pull come and go the rotation toward first direction and second direction, and then make damping mechanism 300 that comes and goes produce the damping, can reach the effect of taking exercise.

In particular, the push-pull handle bar may be arranged in an S-shape. Two push-and-pull handspikes are connected one end that comes and goes damping mechanism and can be close to each other, and two push-and-pull handspikes can keep away from each other gradually from one end to the other end direction, also can make the space grow that supplies the user activity that two push-and-pull handspikes distance crescent more than cushion 111, also can adapt to the user of different sizes. Optionally, the other end of the push-pull handle bar may be provided with a hand-held portion for the user to operate on the arm or wrist. The handheld portion can be the setting of T type, is fixed in the one end of push-and-pull handspike and extends towards the direction of another push-and-pull handspike, also when the user sits on cushion 111, two handheld portions can be close to the user, and convenient to use person operates. The hand-held part can prevent the user from slipping the hand or holding the hand unstably during pushing and pulling. The surface of the hand-held part may be provided with anti-slip lines or coated with anti-slip material to increase friction, for example, the surface may be coated with elastic anti-slip material to increase friction and comfort, which is not limited herein.

Shuttle damping mechanism 300 may include a first drive group 310, a second drive group 320, and a damper 331.

The first transmission set 310 and the second transmission set 320 are arranged between the force receiving mechanism 200 and the damper 331 in parallel. The first transmission set 310 and the second transmission set 320 may be respectively configured to drive the damper 331 to rotate in the same direction in the third direction when the force-receiving mechanism 200 rotates in the first direction and the second direction.

Specifically, when the user pushes and pulls the two push-pull levers, the two push-pull levers rotate back and forth along the first direction and the second direction, so as to drive the first transmission set 310 and the second transmission set 320 to drive the damper 331 to rotate along the same direction along the third direction. That is, when the user pushes the two push-pull levers in the first direction, the damper 331 is driven to rotate in the third direction, and when the user pulls the two push-pull levers in the second direction, the damper 331 is also driven to rotate in the third direction. The damper 331 generates damping in the process of rotating in the third direction to generate a certain resistance to the user pushing and pulling the two push-pull levers, and the user exercises and exercises by overcoming the resistance.

In this embodiment, one side of the exercise device is taken as a viewing direction, and the first direction and the second direction may be clockwise or counterclockwise. The first direction and the second direction are opposite directions to each other. The third direction may be a counterclockwise direction or a clockwise direction. The rotation of the damper 331 in the third direction may mean that the input shaft 332 of the damper 331 rotates in the third direction.

By arranging the force receiving mechanism 200 and the reciprocating damping mechanism 300 on the frame 100, the force receiving mechanism 200 rotates back and forth in the first direction and the second direction under the pushing and pulling action of the user to drive the damper 331 to rotate in the same direction, and the damper 331 can rotate in the third direction no matter the force receiving mechanism 200 rotates in the first direction or in the second direction, during the process of pushing and pulling back and forth, the change of the pushing and pulling direction means that the magnitude change of the force received by the force receiving mechanism 200 is sudden, however, the reciprocating transmission of the force can still enable the damper 331 of the exercise equipment to rotate in the third direction but not rotate in the opposite direction of the third direction, so that the suddenly changed force can be smoothly and softly damped to enable the exercise equipment to stably operate, and when the pushing and pulling hand lever rotates in the first direction, the first transmission group 310 can transmit the power to enable the damper 331 to rotate in the third direction, when the push-and-pull handspike is switched to the second direction and is rotated, second transmission group 320 can transmit power and still make attenuator 331 rotate in the third direction and provide the damping, can provide the damping in two-way effectively, can improve the conveying efficiency to power, promote the availability factor of body-building equipment, and then promote user's use and experience.

Referring to fig. 1, 2 and 3, the first driving group 310 may include a first turntable 311, a first pulley 313 and a first conveyor belt 312. The second transmission set 320 may include a second turntable 321, a second turning wheel 323, a second conveyor belt 322, and at least one auxiliary wheel 324.

The first rotating disk 311 and the second rotating disk 321 may be coaxially fixed to the first rotating shaft 301. The force-receiving mechanism 200 may be connected to the first rotating shaft 301, and is configured to drive the first rotating disk 311 and the second rotating disk 321 to rotate synchronously. Specifically, one end of each of the two push-pull hand levers may be connected to the first rotating shaft 301, and the push-pull hand levers may drive the first rotating shaft 301 to rotate when rotating in the first direction and the second direction. For example, one end of the push-pull handle bar may form a fixing hole, and one end and the other end of the first rotating shaft 301 may penetrate through the fixing hole to be fixedly connected with the push-pull handle bar respectively. Of course, the first rotating shaft 301 may be connected to the push-pull handle through a fixing member, and the fixing member may be disposed in the fixing hole. The fixing member is, for example, a fixing sleeve, which is inserted into the fixing hole and has an end sleeved on the end of the first rotating shaft 301. The connection mode of the two push-pull hand levers and the first rotating shaft 301 may be fixed connection, or may be transmission connection such as a gear, as long as the function that the first rotating shaft 301 drives the first rotating disc 311 and the second rotating disc 321 to synchronously rotate can be realized, and the connection mode is not limited in this specific place.

The first wheel 313 and the second wheel 323 may be coaxially fixed to the second shaft 302. The second rotating shaft 302 is connected to the damper 331. For example, the second rotating shaft 302 may be connected to the input shaft 332 of the damper 331. The first belt 312 may be wound around the first rotating wheel 311 and the first rotating wheel 313, and is configured to drive the damper 331 to rotate in the third direction through the first rotating wheel 313 and the second rotating shaft 302 when the force-receiving mechanism 200 rotates in the first direction. The second belt 322 may be wound around the second turntable 321, the second rotating wheel 323, and the auxiliary wheel 324, and is configured to drive the damper 331 to rotate in the third direction through the second rotating wheel 323 and the second rotating shaft 302 when the force-receiving mechanism 200 is driven in the second direction.

When a user pushes or pulls the two push-pull hand levers in the first direction, the first push-pull hand lever 210 transmits force to the first transmission set 310 along the first direction to drive the first rotating shaft 301 and the first rotating disc 311 to rotate along the first direction, the first rotating disc 311 drives the first rotating wheel 313 to rotate along the first direction through the first transmission belt 312, and then drives the second rotating shaft 302 to rotate along the first direction, and finally drives the damper 331 to rotate along the third direction.

Specifically, the inner side of the first conveyor belt 312 may be in contact with the outer circumferential surface of the first turntable 311 and the outer circumferential surface of the first pulley 313. The inner side of the second conveyor belt 322 may be in contact with the outer circumferential surface of the second turntable 321 and the outer circumferential surfaces of the

auxiliary wheels

324 and 325, and the outer side of the second conveyor belt 322 may be in contact with the outer circumferential surface of the second turning wheel 323.

When the user pulls or pushes the two push-pull levers in the second direction, the second push-pull lever 220 transmits the force to the second transmission set 320 in the second direction, so as to drive the first rotating shaft 301 and the second rotating disc 321 to contact with the outer peripheral surface of the second rotating wheel 323 through the outer side of the second conveyor belt 322, drive the second rotating wheel 323 to rotate in the first direction, further drive the second rotating shaft 302 to still rotate in the first direction, and finally drive the damper 331 to rotate in the same direction in the third direction. Therefore, the damper 331 is driven to rotate in the third direction and generate a damping force corresponding to the rotation of the push-pull lever regardless of whether the push-pull lever rotates in the first direction or the second direction, so that a certain obstacle is generated for the user to push and pull the two push-pull levers, and the user can build body and exercise by overcoming the obstacle.

In order to optimize the structure and realize that the damper 331 is driven to rotate by a relatively small amplitude of push-pull movement, the exercise effect is improved, the diameters of the first rotating disc 311 and the second rotating disc 321 can be the same, the diameters of the first rotating wheel 313 and the second rotating wheel 323 are also the same, and the diameters of the first rotating disc 311 and the second rotating disc 321 are larger than the diameters of the first rotating wheel 313 and the second rotating wheel 323. According to the physical knowledge related to gear transmission, when the diameters of the first rotating disk 311 and the second rotating disk 321 are large to a certain extent, the first rotating disk 311 and the second rotating disk 321 can rotate with relatively small amplitude to drive the first rotating wheel 313 and the second rotating wheel 323 to make circular motion through the transmission belt, and the speed of rotation of the first rotating disk 311 and the second rotating disk 321 also determines the speed of the circular motion of the first rotating wheel 313 and the second rotating wheel 323. The user can push and pull the push-pull handle quickly, so that the first rotating wheel 313 and the second rotating wheel 323 can operate quickly to drive the damper 331 to rotate along the third direction, and the specific diameter ratio of the rotating disc to the rotating wheel can be determined according to actual conditions. Through such diameter size proportion cooperation mode, realize driving the attenuator 331 and rotate with the push-and-pull motion of relative less range, and then produce the hindrance to the user and reach the exercise effect, provide the suitable mode that a better matching user took exercise.

The second conveyor belt 322 and the first conveyor belt 312 are annular, and in order to achieve a bidirectional force transmission effect in a matching manner, the outer peripheral surface of the second conveyor belt 322 is in contact with the outer peripheral surface of the second turntable 321 and the outer peripheral surface of the second rotating wheel 323, so that the

auxiliary wheels

324 and 325 are added, which can be used for limiting, tensioning and transmitting the connection between the second conveyor belt 322 to achieve bidirectional force transmission in a matching manner.

The first rotating wheel 313 and the second rotating wheel 323 can be both one-way rotating wheels, and because the one-way rotating wheels are a one-way mechanism, the one-way rotating wheels can drive the second rotating shaft 302 to rotate in the same direction. The bicycle flywheel is a one-way mechanism, and the one-way mechanism is provided with a ratchet mechanism, an escapement mechanism and the like in a specific form, is used for realizing the motions of feeding, braking, transposition, indexing and the like, and can be viewed from hundred degrees encyclopedias specifically. The first rotating wheel 313 and the second rotating wheel 323 are coaxially fixed on the second rotating shaft 302, when the first rotating wheel 313 rotates along the first direction, the second rotating shaft 302 is driven to rotate in a single direction, and at this time, the second rotating wheel 323 rotates along the second direction relative to the second rotating shaft 302, and the single direction rotation only drives the second rotating shaft 302 along the first direction, so that the driving of the second rotating shaft 302 in the single direction is not affected. When the second wheel 323 rotates along the first direction, the second shaft 302 is driven to rotate along the first direction in a single direction, and at this time, the first wheel 313 rotates along the second direction relative to the second shaft 302, but the second wheel 323 is not influenced to drive the second shaft 302 to rotate in a single direction. Therefore, when the first rotating wheel 313 and the second rotating wheel 323 rotate in opposite directions, the unidirectional rotation of the second rotating shaft 302 is not affected. And when the rotation speed of the first rotating wheel 313 and the second rotating wheel 323 can exceed the rotation speed of the second rotating shaft 302, the second rotating shaft 302 continues to rotate in one direction.

Referring to fig. 3, in order to improve the operation efficiency of the reciprocating damping mechanism 300 and smoothly transmit the force applied by the user to the push-pull rod to the damper 331, the reciprocating damping mechanism 300 of the embodiment may include a third rotating disc 341 and a third transmission belt 342, the third rotating disc 341 is coaxially fixed on the second rotating shaft 302, and the third transmission belt 342 is wound on the third rotating disc 341 and the input shaft 332 of the damper 331, and is configured to drive the damper 331 to rotate along the third direction along with the rotation of the second rotating shaft 302.

When the second rotating shaft 302 rotates along the first direction, the second rotating shaft 302 drives the third rotating disc 341 to rotate along the third direction, so as to drive the third conveying belt 342 to rotate along the third direction, and further drive the input shaft 332 on the damper 331 to rotate along the third direction. So that the damper 331 generates a suitable damping force to generate a certain resistance to the force of the user, thereby achieving the purpose of overcoming the resistance to the user for exercise and fitness.

In order to better improve the transmission efficiency, the diameter of the third rotating disk 341 may be larger than the circumferences of the first rotating disk 311 and the second rotating disk 321, and the specific diameter may be set according to practical situations.

The third rotating disc 341 is coaxially fixed on the second rotating shaft 302, and the third conveyor belt 342 is wound on the third rotating disc 341 and the input shaft 332 of the damper 331, and is configured to drive the damper 331 to rotate along the third direction along with the rotation of the second rotating shaft 302. In particular, the third rotating disk 341 may include an inner disk and an outer ring coaxially disposed, the outer ring surrounding the inner disk. The inner disc is coaxially disposed with the second shaft 302, and the third belt 342 is wound around the outer circumference of the outer ring. The inner disk and the outer ring are connected by a plurality of ribs arranged at intervals, and the plurality of ribs are supported between the inner disk and the outer ring of the third rotating disk 341. Thus, the weight of the third rotating disc 341 can be reduced while the structural stability is ensured, so that the damper 331 is effectively driven to rotate along the third direction.

The damper 331 may be provided with a pinch roller 333. The number of the pinch rollers 333 may be one or more, and is not limited herein. The pinch roller 333 may be used to pinch and confine the third conveyor belt 342. For example, the outer circumferential surface of the third belt 342 contacts the outer circumferential surface of the belt pressing wheel 333 and presses the third belt 342, or the inner circumferential surface of the third belt 342 contacts the outer circumferential surface of the belt pressing wheel 333, so that the third belt 342 is tensioned, and if there are a plurality of belt pressing wheels, the outer circumferential surface of each belt pressing wheel may contact the inner circumferential surface of the third belt 342 or the outer circumferential surface of the third belt 342, which is not limited herein.

In the embodiment, the first conveyor belt 312, the second conveyor belt 322, and the third conveyor belt 342 may be endless transmission chains, and it is understood that other forms of drivable links may also be provided, such as endless transmission belts, which is not limited herein.

If the first belt 312 is a transmission chain, the outer circumferential surface of the first rotary plate 311 may be distributed with saw teeth uniformly arranged for matching with the rotation of the transmission chain. Similarly, if the second conveyor belt 322 is also a transmission chain, the outer circumferential surface of the second turntable 321 may be distributed with uniformly arranged saw teeth for matching with the rotation of the transmission chain.

If the third belt 342 is a transmission belt, grooves for matching the belt may be distributed on the outer circumferential surface of the third rotating disc 341, the outer circumferential surface of the belt pressing rotating wheel 333, and the end of the input shaft 332 connected to the third belt 342, for matching the rotation of the transmission belt.

In a preferred embodiment, the first conveyor belt 312 and the second conveyor belt 322 both use a transmission chain, the first rotating wheel 313 and the second rotating wheel 323 both use a one-way sprocket, so that the first conveyor belt 312 and the first rotating wheel 313 are in a forward meshing state of a chain and a sprocket, the second conveyor belt 322 and the second rotating wheel 323 are in a reverse meshing state of a chain and a sprocket, and the third conveyor belt 342 uses a transmission belt, so that the connection between the third conveyor belt 342 and the damper 331 can play a certain buffering role, and the force combination is more stable.

In order to support the weight of the user and improve the experience effect of the user, the exercise device may further include a seat cushion 111, one end of the seat cushion 111 is provided with a back cushion 112, and the seat cushion 111 and the back cushion 112 are both located inside the force receiving mechanism 200. The contact part of the outer side of the back cushion 112 and the rack 100 is provided with a reinforcing rib for reinforcing and supporting the back cushion 112, and the reinforcing rib is provided with a certain angle according to the actual situation, so that the angle between the back cushion 112 and the rack 100 is 0-90 degrees. The seat cushion 111 is disposed on the trapezoidal inner space of the frame 100, and the first rotary shaft 301, the first rotary plate 311 and the second rotary plate 321 are disposed below the seat cushion 111 to support the weight of the user. Waterproof elastic pads can be arranged on the seat cushion 111 and the back cushion 112, and are used for preventing sweat of a user from immersing in order to maintain the service life of the fitness equipment and avoid sitting posture fatigue brought in the movement process to a certain extent, so that the experience effect of the user is improved.

The damper 331 may be an electromagnetic damper. During the reciprocating process of the push-pull hand lever, because the diameter proportion of the first rotating disc 311 and the first rotating disc 313 is set, the diameter proportion of the second rotating disc 321 and the second rotating disc 323 is set, and the diameter proportion of the first rotating disc 313, the second rotating disc 323 and the third rotating disc 341 are matched, the force can be transmitted to the electromagnetic damper rapidly and bidirectionally. Specifically, when a user pushes and pulls the handle bar back and forth, force is transmitted to the first rotating disc 311 and the second rotating disc 321, so that the first rotating disc 311 and the second rotating disc 321 are driven to rotate back and forth, the first rotating disc 311 and the second rotating disc 321 which rotate back and forth drive the first rotating shaft 301 to rotate back and forth, when the first transmission set 310 drives the first rotating disc 313 in the first direction, so that the second rotating shaft 302 is driven to rotate in the first direction, at the moment, the second rotating disc 323 rotates in the second direction, but the second rotating shaft 302 is not influenced to rotate in the first direction, the rotating second rotating shaft 302 drives the third rotating disc 341 to rotate in a single direction, and the third rotating disc 341 drives the input shaft 332 to rotate in a single direction through the third transmission belt 342, so that the electromagnetic damper is driven to rotate in the third direction, so that self. When the second transmission set 320 drives the second rotating wheel 323 in the second direction to drive the second rotating shaft 302 to rotate along the first direction, at this time, the first rotating wheel 313 rotates along the second direction without affecting the rotation of the second rotating shaft 302 along the first direction, the rotating second rotating shaft 302 drives the third rotating disc 341 to rotate in a single direction, and the third rotating disc 341 drives the input shaft 332 to rotate in a single direction through the third conveyor belt 342 to drive the electromagnetic damper to rotate along the third direction to perform self-generating. The electromagnetic damper generates a reverse magnetic resistance force that hinders the damper 331 from rotating by a current generated by self-generation. According to practical situations, the magnitude of the reverse reluctance force is suitable for the magnitude of the force received by the force receiving mechanism 200.
