Description

Technical Field

[0001] The present application relates to the field of fitness equipment, and in particular to an all-round fitness bicycle. Background Art

[0002] As a common piece of exercise equipment, fitness bikes are widely used in homes, gyms, and other places. As people pay more attention to health and physical training, the design of fitness bikes has gradually developed in a diversified and functional direction, aiming to provide a more comprehensive exercise experience and training effect.

[0003] In the related art, traditional fitness bicycles mainly achieve aerobic exercise through the rotational movement of pedals.

[0004] The above-mentioned related technologies have the following defects: traditional fitness bicycles mainly exercise people's legs, and often do not exercise the upper limbs and waist properly. Summary of the Invention

[0005] In order to exercise the lower limbs, upper limbs and waist, the present application provides an all-round exercise fitness bicycle.

[0006] The present application provides an all-around exercise fitness bicycle that adopts the following technical solutions: An all-around exercise fitness bicycle comprises a frame, a rear reciprocating mechanism, a seat, two forward reciprocating mechanisms, and two handlebars corresponding to the two forward reciprocating mechanisms. A front main gear and a rear main gear are provided at the front and rear ends of the frame, respectively. The front main gear and the rear main gear are connected by a chain. Pedals are mounted on the rear main gear. The rear reciprocating mechanism includes an annular bracket slidably connected to the frame in the axial direction of the rear main gear and a sector gear rotatably mounted in the annular bracket, and the seat is mounted on the upper end of the annular bracket; An upper rack and a lower rack are provided on the inner side of the annular bracket in parallel with each other. Both the upper rack and the lower rack are arranged along the axis of the rear main gear. The sector gear is meshed with the upper rack or the lower rack. The rear main gear is provided with a sub-gear for driving the sector gear to rotate. The two forward reciprocating movement mechanisms are respectively arranged on both sides of the front main gear; the forward reciprocating movement mechanism includes a first turntable, a second turntable and a swing link, and the edges of the first turntable and the second turntable are rotatably connected to the swing link; the first turntable is coaxially connected to the front main gear; the second turntable is coplanar with the first turntable and is rotatably connected to the frame; the handlebars are connected to the corresponding swing links.

[0007] By adopting the above technical solution, when a user sits on the seat and pedals, the rear main gear rotates, and through the chain, the front main gear rotates, allowing the user to exercise their lower limbs by pedaling. The rotation of the front main gear drives the first rotating disk to rotate, and in conjunction with the position limit of the second rotating disk, it drives the swing link to swing back and forth, thereby achieving reciprocating swing of the handlebars. At this time, the user holds the handlebars with both hands, and the handlebars drive the user's upper limbs to swing, achieving upper limb exercise. When the rear main gear rotates, it drives the secondary gear to rotate, which drives the sector gear to rotate. When the teeth of the sector gear face the upper rack, the sector gear meshes only with the upper rack. At this time, the rotating sector gear drives the upper rack toward the first side of the frame, thereby driving the support and seat toward the first side of the frame. When the teeth of the sector gear face the lower rack, the sector gear meshes only with the lower rack. At this time, the rotating sector gear drives the lower rack toward the second side of the frame, thereby driving the support and seat toward the second side of the frame. When the sector gear rotates and meshes with the upper and lower racks in sequence, the seat can also reciprocate in the direction of the rear main gear axis. When the user sits on the seat, the user's hips and waist can reciprocate with the seat in the direction of the rear main gear axis, thereby achieving the purpose of exercising the user's waist. In summary, this application can exercise the user's lower limbs, upper limbs, and waist, allowing the user to achieve full-scale exercise during riding, further enhancing the user's overall exercise effect.

[0008] Preferably, the rear reciprocating mechanism comprises a reversing gear rotatably connected to the frame and a prism tube coaxially connected to the reversing gear, and the reversing gear is vertically meshed with the pinion gear; A coaxial rib rod is provided on the inner side of the rib tube, the rib rod is rotatably connected to the vehicle frame, and is also slidably connected to the vehicle frame in the axial direction of the rib tube; The sector gear is coaxially mounted on the rib rod.

[0009] By adopting this technical solution, the vertical meshing of the reversing gear and the pinion gear enables directional power transmission. When the seat needs to reciprocate, the ribbed rod is inserted into the ribbed tube, allowing the reversing gear to rotate the ribbed rod, which in turn rotates the sector gear, driving the annular bracket and the seat to reciprocate. When the seat is no longer required to reciprocate, the ribbed rod is moved away from the ribbed tube, disconnecting the two and thus stopping the seat from moving.

[0010] Preferably, a first bearing and a second bearing are sleeved on the prism rod, and in the axial direction of the prism tube, the first bearing and the second bearing are both slidably connected to the vehicle frame.

[0011] By adopting the above technical solution, the arrangement of the first bearing and the second bearing can effectively support the prism rod and ensure its stable sliding in the axial direction of the prism tube; at the same time, the sliding connection between the two bearings and the frame enables the prism rod to have higher motion accuracy and stability when subjected to radial force and axial force, thereby improving the overall operation reliability of the rear reciprocating movement mechanism.

[0012] Preferably, the outer ring of the first bearing is connected to the frame with a first reset elastic member arranged along the axis direction of the prism tube; The outer ring of the second bearing is provided with a radially arranged push plate, and the push plate is slidably connected to the vehicle frame in the axial direction of the prism tube.

[0013] By adopting the above technical solution, the rib rod is moved by pushing the push plate, thereby disconnecting the rib rod from the rib tube. After the thrust applied to the push plate is released, the first resetting elastic member can provide a resetting force along the axis of the rib tube to the first bearing, thereby allowing the rib rod to be reinserted into the rib tube and maintaining the connection between the rib rod and the rib tube.

[0014] Preferably, a conical piece is provided between the push plate and the prism tube, and the side wall of the conical piece is a smooth side wall and contacts the push plate; The outer diameter of the tapered member increases gradually from the inner ring to the outer ring of the second bearing, and the tapered member is also slidably connected to the vehicle frame in the radial direction of the second bearing.

[0015] By adopting the above technical solution, when the conical member moves toward the second bearing, the push plate slides along the side wall of the conical member toward the end with the larger diameter of the conical member, thereby pushing the push plate away from the rib tube until the rib rod and the rib tube are separated. When the conical member moves away from the second bearing, the push plate slides along the side wall of the conical member toward the end with the smaller diameter of the conical member, thereby pushing the push plate toward the rib tube until the rib rod is inserted into the rib tube.

[0016] Preferably, the end of the conical member with a larger diameter is connected to the frame with a third reset elastic member; the outer wall of the frame is installed with a wire take-up member, and the wire take-up member and the end of the conical member with a larger diameter are connected to a brake line.

[0017] By adopting the above technical solution, the wire take-up member pulls the brake wire, moving the tapered member away from the second bearing. When the wire take-up member releases the tension, the third resetting elastic member drives the tapered member back to its original position, bringing the tapered member closer to the second bearing, thereby achieving precise control of the tapered member's position.

[0018] Preferably, in the axial direction of the rear main gear, both ends of the annular bracket are connected to the vehicle frame with a second reset elastic member.

[0019] By employing this technical solution, disconnecting the ribbed rod and ribbed tube allows the second resilient member to reset the annular bracket, thereby resetting the seat. This also allows the annular bracket to automatically reset itself as it reciprocates along the axis of the rear main gear. This design not only simplifies user operation but also effectively improves the continuity and smoothness of movement, while also enhancing the stability and reliability of the device.

[0020] Preferably, a first rotating shaft is axially arranged on the outer edge of the first rotating disk, and the first rotating shaft is rotatably connected to the first rotating disk and the swing connecting rod; A second rotating shaft is axially arranged on the outer edge of the second rotating disk, and the second rotating shaft is rotatably connected to the second rotating disk and the swing connecting rod.

[0021] By adopting this technical solution, the first and second turntables are rotatably connected to the swing link via the first and second rotating shafts, respectively. This structural design makes the forward and backward movement mechanism more flexible and smooth, effectively reducing frictional resistance during movement and enhancing the user's exercise experience. It also enhances the structural stability and durability, ensuring reliable performance over long-term use.

[0022] Preferably, a coaxial connecting gravity wheel is provided on the front main gear.

[0023] By adopting this technical solution, the connected gravity wheel increases the rotational inertia of the front main gear, forcing the user to overcome greater resistance when stepping on the pedals, thereby enhancing the exercise effect. Furthermore, the addition of the connected gravity wheel improves smoothness during exercise, reducing shaking caused by sudden force application or stopping, and improving the user experience.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. In this application, the coordinated cooperation of the foot pedal, the rear reciprocating mechanism and the forward reciprocating mechanism realizes the coordinated full-range movement of the user's lower limbs, upper limbs and waist, allowing the user's whole body to participate in the exercise at the same time, meeting the demand for balanced exercise of the whole body muscles.

[0025] 2. The annular bracket and sector gear design in the rear reciprocating mechanism of this application, combined with the sub-gear drive, enable the seat to slide back and forth along the frame, thereby enhancing the training effect of the leg muscles and improving the diversity and intensity of the exercise.

[0026] 3. In the present application, when the front main gear rotates, it drives the first turntable to rotate, and cooperates with the limit of the second turntable to drive the swing link to swing back and forth, thereby realizing the reciprocating swing of the handlebars. At this time, the user holds the handlebars with both hands, and the handlebars drive the user's upper limbs to swing, thereby realizing the exercise of the upper limbs.

[0027] 4. In the present application, when the sector gear rotates and engages with the upper rack and the lower rack in sequence, the seat can also move back and forth in the axis direction of the rear main gear. Then, when the user sits on the seat, the user's buttocks and waist can move back and forth with the seat in the axis direction of the rear main gear, so as to achieve the purpose of exercising the user's waist.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses an all-round sports fitness bicycle.

[0033] Reference Figure 1 、 Figure 2 and Figure 3A full-range exercise fitness bicycle includes a frame 1, a rear reciprocating mechanism 2, a seat 4, two forward reciprocating mechanisms 3, and two handlebars 5 corresponding to the two forward reciprocating mechanisms 3. A front main gear 11 and a rear main gear 12 are respectively provided at the front and rear ends of the frame 1. The front and rear main gears 11 and 12 are connected by a chain 14. Pedals 15 are mounted on the rear main gear 12. When a user sits on the seat 4 and steps on the pedals 15, the rear main gear 12 rotates, and the front main gear 11 is driven to rotate via the chain 14. The user exercises their lower limbs by stepping on the pedals 15. The front main gear 11 is provided with a coaxially connected gravity wheel 10. The side of the gravity wheel 10 is provided with an adjustment bolt that is threaded with the frame 1. The adjustment bolt is radially arranged on the side of the gravity wheel 10, and a brake pad is provided on the end of the adjustment bolt facing the gravity wheel 10. By rotating the adjustment bolt, the distance between the brake pad and the gravity wheel 10 and the force of the brake pad pressing on the side wall of the gravity wheel 10 are adjusted, thereby adjusting the resistance of the user to the pedal 15, so that the user can exercise the lower limbs with different strengths. In addition, the setting of the gravity wheel 10 can increase the rotational inertia of the front main gear 11, so that the user needs to overcome greater resistance when stepping on the pedal 15, thereby enhancing the exercise effect. Reference Figure 1 、 Figure 2 and Figure 3 The rear reciprocating mechanism 2 includes an annular bracket 23 that is slidably connected to the vehicle frame 1 along the axis of the rear main gear 12, and a sector gear 24 that is rotatably mounted within the annular bracket 23. The seat 4 is mounted on the upper end of the annular bracket 23. An upper rack 231 and a lower rack 232 are disposed within the annular bracket 23, arranged parallel to each other. Both the upper rack 231 and the lower rack 232 are disposed along the axis of the rear main gear 12, and the sector gear 24 meshes with either the upper rack 231 or the lower rack 232. The rear main gear 12 is provided with a pinion 13 that drives the sector gear 24. When the rear main gear 12 rotates, the pinion 13 rotates, which in turn drives the sector gear 24. When the teeth of the sector gear 24 face the upper rack 231, the sector gear 24 meshes only with the upper rack 231. The rotating sector gear 24 then drives the upper rack 231 toward the first side of the frame 1, thereby driving the support bracket and the seat 4 toward the first side of the frame 1. When the teeth of the sector gear 24 face the lower rack 232, the sector gear 24 meshes only with the lower rack 232. The rotating sector gear 24 then drives the lower rack 232 toward the second side of the frame 1, thereby driving the support bracket and the seat 4 toward the second side of the frame 1. As the sector gear 24 rotates, it sequentially meshes with the upper rack 231 and the lower rack 232, allowing the seat 4 to reciprocate along the axis of the rear main gear 12. Consequently, when a user sits on the seat 4, the user's hips and waist reciprocate with the seat 4 along the axis of the rear main gear 12, thereby exercising the user's waist.

[0034] Reference Figure 1 、 Figure 2 and Figure 3 , two forward reciprocating movement mechanisms 3 are respectively arranged on both sides of the front main gear 11. The forward reciprocating movement mechanism 3 includes a first turntable 31, a second turntable 32 and a swing link 33. The edges of the first turntable 31 and the second turntable 32 are rotatably connected to the swing link 33. The first turntable 31 is coaxially connected to the front main gear 11. The second turntable 32 is coplanar with the first turntable 31 and is rotatably connected to the frame 1. The handlebar 5 is connected to the corresponding swing link 33. When the front main gear 11 rotates, it drives the first turntable 31 to rotate, and cooperates with the limit of the second turntable 32 to drive the swing link 33 to swing back and forth, thereby realizing the reciprocating swing of the handlebar 5. At this time, the user holds the handlebar 5 with both hands, and the handlebar 5 drives the user's upper limbs to swing, realizing the exercise of the upper limbs.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 The rear reciprocating mechanism 2 includes a reversing gear 21, which is rotationally connected to the vehicle frame 1, and a prism 211, which is coaxially connected to the reversing gear 21. The reversing gear 21 is vertically meshed with the pinion 13. A coaxial prism 22 is provided inside the prism 211. The prism 22 is rotationally connected to the vehicle frame 1 and is also slidably connected to the vehicle frame 1 along the axis of the prism 211. A sector gear 24 is coaxially mounted on the prism 22.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 In this embodiment, the vertical meshing of the reversing gear 21 and the pinion 13 enables the transfer of power. When the seat 4 is required to reciprocate, the ribbed rod 22 is inserted into the ribbed tube 211, allowing the reversing gear 21 to rotate the ribbed rod 22. The ribbed rod 22 then rotates the sector gear 24, driving the annular bracket 23 and the seat 4 to reciprocate. When the seat 4 is no longer required to reciprocate, the ribbed rod 22 moves away from the ribbed tube 211, disconnecting the ribbed rod 22 and the ribbed tube 211, and thus disabling the seat 4.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 The prism rod 22 is provided with a first bearing 221 and a second bearing 224. In the axial direction of the prism tube 211, the first bearing 221 and the second bearing 224 are both slidably connected to the frame 1. Specifically, the first bearing 221 and the second bearing 224 are both slidably connected to the frame 1 through a slide rail.

[0038] Reference Figure 1 、 Figure 2 and Figure 3In the present embodiment, the arrangement of the first bearing 221 and the second bearing 224 effectively supports the rib bar 22, ensuring its stable sliding along the axis of the rib tube 211. Furthermore, the sliding connection between the two bearings and the vehicle frame 1 allows the rib bar 22 to achieve greater motion accuracy and stability when subjected to radial and axial forces, thereby improving the overall operational reliability of the rear reciprocating mechanism 2.

[0039] Reference Figure 1 、 Figure 2 and Figure 3 The outer ring of the first bearing 221 is connected to the vehicle frame 1 via a first resilient member 222 disposed along the axis of the prism tube 211. Specifically, the first resilient member 222 can be any elastic member capable of resetting upon compression, such as a first spring rod. The outer ring of the second bearing 224 is provided with a radially disposed push plate 223, which is slidably connected to the vehicle frame 1 along the axis of the prism tube 211.

[0040] Reference Figure 1 、 Figure 2 and Figure 3 In the embodiment of the present application, the rib rod 22 is moved by pushing the push plate 223, thereby disconnecting the rib rod 22 from the rib tube 211. After the thrust applied to the push plate 223 is released, the first return elastic member 222 can provide a return force along the axis of the rib tube 211 for the first bearing 221, thereby allowing the rib rod 22 to be reinserted into the rib tube 211 and maintaining the connection between the rib rod 22 and the rib tube 211.

[0041] Reference Figure 1 、 Figure 2 and Figure 3 A tapered member 25 is provided between the push plate 223 and the prism 211. The sidewalls of the tapered member 25 are smooth and in contact with the push plate 223. The outer diameter of the tapered member 25 increases from the inner ring to the outer ring of the second bearing 224. The tapered member 25 is also slidably connected to the vehicle frame 1 in the radial direction of the second bearing 224.

[0042] Reference Figure 1 、 Figure 2 and Figure 3 In the embodiment of the present application, when the conical member 25 moves toward the second bearing 224, the push plate 223 slides along the sidewall of the conical member 25 toward the end with the larger diameter of the conical member 25, thereby pushing the push plate 223 away from the prism tube 211 until the prism rod 22 and the prism tube 211 are separated. When the conical member 25 moves away from the second bearing 224, the push plate 223 slides along the sidewall of the conical member 25 toward the end with the smaller diameter of the conical member 25, thereby pushing the push plate 223 toward the prism tube 211 until the prism rod 22 is inserted into the prism tube 211.

[0043] Reference Figure 1 、 Figure 2 and Figure 3 The larger diameter end of the conical member 25 is connected to the vehicle frame 1 via a third resilient member 251. Specifically, the third resilient member 251 can be any elastic member capable of resetting upon compression, such as a third spring rod. A wire take-up member 253 is mounted on the outer wall of the vehicle frame 1. The wire take-up member 253 and the larger diameter end of the conical member 25 are connected to a brake cable 252. Specifically, the wire take-up member 253 is a hasp lock, the locking tongue of which is connected to the brake cable 252. When the hasp lock is unlocked, the locking tongue of the hasp lock is away from the hasp lock buckle, and the brake cable 252 is relaxed. The resilient force of the third resilient member 251 drives the conical member 25 toward the second bearing 224. When the hasp lock is locked, the locking tongue of the hasp lock is close to the hasp lock buckle, and the brake cable 252 is taut, pulling the conical member 25 away from the second bearing 224. Alternatively, the wire take-up member 253 may be a wire take-up wheel with a self-locking function or any other structure capable of retracting and releasing the wire.

[0044] Reference Figure 1 、 Figure 2 and Figure 3 In the embodiment of the present application, the wire take-up member 253 pulls the brake wire 252, moving the conical member 25 away from the second bearing 224. When the wire take-up member 253 releases the tension, the third reset elastic member 251 drives the conical member 25 to reset, moving the conical member 25 closer to the second bearing 224, thereby achieving precise control of the position of the conical member 25.

[0045] Reference Figure 1 、 Figure 2 and Figure 3 In the axial direction of the rear main gear 12, both ends of the annular bracket 23 are connected to the frame 1 with a second reset elastic member 233. Specifically, the second reset elastic member 233 can be an elastic member that can be reset after being compressed, such as a second spring rod.

[0046] Reference Figure 1 、 Figure 2 and Figure 3 In this embodiment, by disconnecting the rib rod 22 from the rib tube 211, the second resetting elastic member 233 can drive the annular bracket 23 to reset, thereby resetting the seat 4. This also allows the annular bracket 23 to automatically reset itself as it reciprocates along the axis of the rear main gear 12. This design not only simplifies user operation but also effectively improves the continuity and smoothness of movement, while also enhancing the stability and reliability of the device.

[0047] Reference Figure 1 、 Figure 2 and Figure 3The outer edge of the first rotating disk 31 is provided with an axially arranged first rotating shaft 311, and the first rotating shaft 311 is rotatably connected to the first rotating disk 31 and the swing link 33. The outer edge of the second rotating disk 32 is provided with an axially arranged second rotating shaft 321, and the second rotating shaft 321 is rotatably connected to the second rotating disk 32 and the swing link 33.

[0048] Reference Figure 1 、 Figure 2 and Figure 3 In this embodiment, the first rotating disk 31 and the second rotating disk 32 are rotationally connected to the swing link 33 via a first rotating shaft 311 and a second rotating shaft 321, respectively. This structural design makes the movement of the reciprocating mechanism 3 more flexible and smooth, effectively reducing frictional resistance during movement and improving the user's exercise experience. This design also enhances the stability and durability of the structure, ensuring reliable performance even under long-term use.

[0049] The operating principle of the omnidirectional exercise bicycle according to the present invention is as follows: When a user sits on the seat 4 and pedals 15, the rear main gear 12 rotates, driving the front main gear 11 to rotate via the chain 14. The user's pedaling 15 exercises their lower limbs. The rotation of the front main gear 11 drives the first rotating disk 31, which, in conjunction with the position control of the second rotating disk 32, drives the swing link 33 to swing back and forth, thereby achieving reciprocating swing of the handlebars 5. At this point, the user holds the handlebars 5 with both hands, and the handlebars 5 swing the user's upper limbs, thereby exercising their upper limbs. The rotation of the rear main gear 12 drives the secondary gear 13 to rotate, which in turn drives the sector gear 24 to rotate. When the teeth of the sector gear 24 face the upper rack 231, the sector gear 24 meshes exclusively with the upper rack 231. The rotating sector gear 24 then drives the upper rack 231 toward the first side of the frame 1, thereby driving the support bracket and the seat 4 toward the first side of the frame 1. When the teeth of the sector gear 24 face toward the lower rack 232, the sector gear 24 meshes only with the lower rack 232. The rotating sector gear 24 then drives the lower rack 232 toward the second side of the frame 1, thereby driving the bracket and seat 4 toward the second side of the frame 1. As the sector gear 24 rotates, it sequentially meshes with the upper rack 231 and the lower rack 232, allowing the seat 4 to reciprocate along the axis of the rear main gear 12. When a user sits on the seat 4, the user's hips and waist reciprocate with the seat 4 along the axis of the rear main gear 12, thereby exercising the user's waist. In summary, this application allows the user to exercise their lower limbs, upper limbs, and waist, enabling them to achieve a full range of motion while riding, thereby enhancing the overall exercise effect.
