Description

Technical Field

[0001] This invention belongs to the field of fitness equipment technology, and specifically relates to a multi-functional exercise bike. Background Technology

[0002] Fitness equipment is a general term for sports equipment used for physical training. According to function, it can be divided into two main categories: single-function equipment such as treadmills, rowing machines, and elliptical trainers, and comprehensive multi-functional equipment. Exercise bikes are a common type of fitness equipment, which users can use to imitate cycling.

[0003] Most exercise bikes on the market are single-function devices, only allowing for cycling movements. For example, a spinning bike disclosed in Chinese invention patent application CN 202510712170.0 includes a base and a frame rotatably mounted on the base in a front-to-back direction. The bottom end of the frame has a front connecting end and a rear connecting end located on either side of its hinge point. The rear connecting end is characterized by an elastic buffer element between it and the base. The base has a pitch adjustment assembly comprising a lead screw, a drive block, an adjusting rod, and a drive motor. The lead screw is rotatably mounted on the base, and the drive block is slidably mounted on the base. The lead screw passes through the drive block and engages with it in a helical transmission. Positioning blocks capable of locking with the base are located on both sides of the drive block. When the lead screw rotates, the positioning blocks unlock from the base, allowing the drive block to move. The two ends of the adjusting rod are respectively connected to the front connecting end and the drive block. The drive motor is mounted on the base, and its output shaft is connected to the lead screw.

[0004] The aforementioned exercise bikes have a single purpose, which leads to higher fitness costs for users. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a multi-functional exercise bike that is convenient for users to use.

[0006] The objective of this invention is achieved as follows:

[0007] A multi-functional exercise bike includes a frame, a handlebar mechanism, a seat mechanism, and a pedaling mechanism on the frame. The pedaling mechanism includes a drive wheel rotatably mounted on the frame, with drive arms on both sides of the drive wheel. The drive arms control the rotation of the drive wheel. A tray and an eccentric drive device are movably mounted on the frame. The eccentric drive device is equipped with a transmission component and an eccentric component connected to the tray. The drive wheel drives the transmission component to rotate through a mechanical transmission structure, which in turn causes the eccentric component to rotate, thereby causing the tray to vibrate through the eccentric component.

[0008] The pallet is rotatably mounted on the frame via a hinge shaft, and the eccentric component is located on one side of the hinge shaft or on one side of the extension direction of the hinge shaft. The eccentric component can drive the pallet to swing back and forth with the frame.

[0009] The frame is provided with two sets of hinge seats, and the eccentric drive device is rotatably connected to the two sets of hinge seats respectively. The eccentric part is located between the two sets of hinge seats, and the transmission part is located on the same side of the two sets of hinge seats.

[0010] The present invention is further configured such that: the pallet is provided with a connecting seat that is connected to the eccentric component, the outer periphery of the eccentric component is provided with a spherical surface, the connecting seat is provided with a connecting groove that is adapted to the spherical surface, and the connecting groove is universally connected to the spherical surface.

[0011] The present invention is further configured such that: an acceleration wheel is provided on the frame, the acceleration wheel includes a large wheel part and a small wheel part, the drive wheel and the small wheel part are transmitted through a first transmission belt, and the large wheel part drives the transmission component to move through a second transmission belt.

[0012] The invention is further configured such that: a mounting base is provided on the frame, and the mounting base is respectively provided with a first mounting groove and a second mounting groove for mounting the drive wheel and the acceleration wheel; a first rotating shaft and a second rotating shaft are respectively provided on the drive wheel and the acceleration wheel; the first mounting groove and the second mounting groove are respectively provided with a first opening and a second opening; the second mounting groove is located on the side of the first mounting groove away from the first opening, and the second opening faces the side of the second mounting groove away from the first opening; a first transmission belt connects the drive wheel to the small wheel portion, and allows the first rotating shaft and the second rotating shaft to directly or indirectly abut against the bottom of the first mounting groove and the second mounting groove, respectively.

[0013] The invention is further configured such that: the transmission component is disposed on the side of the second mounting groove away from the second opening, and the second transmission belt can drive the acceleration wheel to press against the bottom of the second mounting groove.

[0014] The present invention is further configured such that: a vertical pole for mounting the handlebar mechanism is provided on the base, a pedal mechanism and a support plate are respectively provided on both sides of the vertical pole, and the pedal mechanism is provided between the seat mechanism and the vertical pole.

[0015] The invention is further configured such that: the support plate is rotatably mounted on the upright via a hinge shaft, and a swing groove is provided on the side of the support plate near the upright, with the upright passing through the swing groove, which can limit the relative rotation range between the support plate and the upright.

[0016] The present invention is further configured such that: the seat mechanism includes a seat body and a sliding rod, a vertically extending mounting tube is provided on the frame, the sliding rod slides in the mounting tube and can be fixed relative to the mounting tube by fasteners, a horizontally extending sliding groove is provided on the sliding rod, the seat body can slide horizontally along the sliding rod, and a locking member is provided on the seat body to control the seat body to be fixed relative to the sliding groove.

[0017] The advantages of this invention compared to the prior art are:

[0018] 1. In this invention, the user can move through the handlebar mechanism, seat mechanism, and pedal mechanism. The drive wheel in the pedal mechanism can drive the tray to vibrate through an eccentric drive device, thus enabling the multi-functional exercise bike to be used as a fat-burning machine. This enhances the functionality of the multi-functional exercise bike, allowing the user to perform two types of exercise or cycle alone. The user can also adjust the resistance during cycling by placing items of different weights on the tray, providing flexibility. In this structure, the tray is rotatably mounted on the frame via a hinge shaft. During use, the pedal mechanism drives the tray to swing back and forth through the eccentric drive device, enabling the multi-functional exercise bike to function as a fat-burning machine. This structure is simple and easy to manufacture and assemble.

[0019] 2. The spherical surface on the eccentric component and the connecting groove on the connecting seat in this invention facilitate the flexible movement of the eccentric component and the tray during use, avoid the eccentric component and the tray getting stuck and damaged during use, and promote the flexible movement of the tray, making it convenient for users to use.

[0020] 3. The acceleration wheel in this invention increases the rotational speed of the transmission components during use, thereby increasing the vibration frequency of the support plate and improving its fitness effect. This structure also increases the damping of the pedaling mechanism during use, enhancing the intensity of bicycle exercise and facilitating user training. Since the second mounting groove is located on the side of the first mounting groove away from the first opening, and the second opening faces the side of the second mounting groove away from the first opening, the first transmission belt ensures that the first and second shafts are directly or indirectly pressed against the bottom of the first and second mounting grooves, respectively, preventing the drive wheel and acceleration wheel from becoming loose during use, thus facilitating user operation. Furthermore, since the transmission components are located on the side of the second mounting groove away from the second opening, the second transmission belt can drive the acceleration wheel to press against the bottom of the second mounting groove, preventing the acceleration wheel from becoming loose during use, further facilitating user operation.

[0021] 4. In this invention, since the pedaling mechanism and the support plate are respectively set on both sides of the upright, the user's feet will not touch the user on the support plate during the use of the bicycle, which makes it convenient for the user to use. The setting of the swing groove can reduce the distance between the center of gravity of the support plate and the upright, avoid the bending and damage of the hinge shaft, and this structure can prevent the support plate from rotating too much, which would cause damage to the connection position between the support plate and the eccentric part, thus helping to extend the service life of the multi-functional exercise bike.

[0022] 5. The design of the seat body and sliding rod in this invention allows users to flexibly adjust the seat body horizontally and vertically as needed, making it convenient for users to use. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0035] See Figures 1 to 10 As shown, a multi-functional exercise bike includes a frame 1, a handlebar mechanism 2, a seat mechanism 3, and a pedaling mechanism 4 mounted on the frame 1. The pedaling mechanism 4 includes a drive wheel 41 rotatably mounted on the frame 1, with drive arms 42 on both sides of the drive wheel 41. The drive arms 42 control the rotation of the drive wheel 41. A tray 5 and an eccentric drive device 6 are movably mounted on the frame 1. The eccentric drive device 6 is equipped with a transmission component 61 and an eccentric component 62 connected to the tray 5. The drive wheel 41 drives the transmission component 61 to rotate through a mechanical transmission structure, causing the eccentric component 62 to rotate, thereby causing the tray 5 to rotate through the eccentric component 62. Vibration: In this structure, the user can move through the handlebar mechanism 2, seat mechanism 3, and pedal mechanism 4. The drive wheel 41 in the pedal mechanism 4 can drive the tray 5 to vibrate through the eccentric drive device 6, so that the multi-functional exercise bike can be used as a rhythm machine or a fat-burning machine, which is beneficial to increase the functionality of the multi-functional exercise bike. During use, the user can use two types of exercise, or the user can exercise by cycling alone, which is convenient for the user. During use, the user can adjust the resistance during cycling by placing items of different weights on the tray 5, which is convenient for the user to adjust flexibly.

[0036] The mechanical transmission structure can be a belt drive, rope drive, or friction wheel drive, etc. It can also be a gear drive, chain drive, helical drive, or harmonic drive, etc. These structures are common mechanical transmission structures in the field. Therefore, although not all mechanical transmission structures are described in this application, those skilled in the art can implement the above-mentioned mechanical transmission structures based on their own knowledge.

[0037] In this invention, the tray 5 can be rotatably mounted on the frame 1, and the tray 5 can also be slidably mounted on the frame 1.

[0038] In this invention, the tray 5 is preferably rotatably mounted on the frame 1, and the eccentric component 62 is located on one side of the hinge shaft 14 or on one side of the extension direction of the hinge shaft 14. The eccentric component 62 can drive the tray 5 to swing back and forth with the frame 1. During use, the pedaling mechanism 4 will drive the tray 5 to swing back and forth through the eccentric drive device 6, so that the multi-functional exercise bike can be used as a fat-burning machine. This structure is simple and convenient for production and assembly.

The eccentric drive device 6 is rotatably connected to the two sets of hinge seats 15 respectively, and the eccentric member 62 is located between the two sets of hinge seats 15. This structure is conducive to the stable rotation of the eccentric member 62. The transmission member 61 is located on the same side of the two sets of hinge seats 15. This structure is conducive to reducing the force arm on the hinge shaft 14 when the transmission member 61 is subjected to force, and avoiding the bending of the hinge shaft 14 from affecting the normal use of the multi-functional exercise bike.

[0040] The pallet 5 is provided with a connecting seat 51 connected to the eccentric member 62. The outer periphery of the eccentric member 62 is provided with a spherical surface 63. The connecting seat 51 is provided with a connecting groove 52 adapted to the spherical surface 63. The connecting groove 52 and the spherical surface 63 are universally connected. The spherical surface 63 on the eccentric member 62 and the connecting groove 52 on the connecting seat 51 facilitate the flexible movement of the eccentric member 62 and the pallet 5 during use, avoid the eccentric member 62 and the pallet 5 getting stuck and damaged during use, and facilitate the flexible movement of the pallet 5, making it convenient for the user. In this embodiment, the eccentric drive device 6 includes a drive shaft 64. The drive member 61 and the eccentric member 62 are both fixedly mounted on the drive shaft 64.

[0042] The frame 1 described in this invention is equipped with an acceleration wheel 7, which includes a large wheel and a small wheel. The drive wheel 41 and the small wheel are connected by a first transmission belt 71. The large wheel drives the transmission component 61 to move through a second transmission belt 72. The acceleration wheel 7 increases the rotational speed of the transmission component 61 during use, thereby increasing the vibration frequency of the tray 5 and improving the fitness effect of the tray 5. Furthermore, this structure can increase the damping of the pedaling mechanism 4 during use, which helps to increase the intensity of bicycle exercise and facilitates user training.

This structure is conducive to the stable installation of the drive wheel 41 and the acceleration wheel 7, avoids the drive wheel 41 and the acceleration wheel 7 from loosening during use, and is convenient for users.

[0045] Preferably, the transmission component 61 is located on the side of the second mounting groove 132 away from the second opening. The second transmission belt 72 can drive the acceleration wheel 7 to press against the bottom of the second mounting groove 132.
