Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, specifically to an elliptical bike. Background Technology

[0002] The elliptical trainer, also known as an elliptical walking machine, is a popular exercise tool for cardiovascular fitness, favored by many users and professionals. Its incline design, adjustable resistance, choreographed exercise patterns, and ability to specifically target lower limb muscles make it a common piece of exercise equipment in professional gyms and home living rooms. A key advantage of the elliptical trainer is that there is no point of impact on the knee joints during use. Using an elliptical trainer can not only prevent, reduce, and alleviate pain in the neck, shoulder, and upper back, but also avoid the impact of running, better protecting the joints and thus providing a higher level of safety.

[0003] Elliptical bikes require a certain amount of resistance during exercise, and different resistance levels are needed to balance the resistance for people of different weights. Existing adjustment methods are divided into contact and non-contact resistance adjustment structures. Taking non-contact as an example, magnetic resistance adjustment is usually used. However, existing magnetic resistance adjustment is all single-sided adjustment. Whether it is a manual knob, due to interval issues, it can only divide the resistance into 8 levels or 32 levels, or a cable motor can be adjusted more precisely, the maximum and minimum values ​​of the adjustment remain unchanged. That is to say, the number of people suitable for the same equipment is also limited.

[0004] In the process of realizing this utility model, this application discovered that in the prior art, the magnetic control resistance adjustment of the circular wheel is all unilateral resistance adjustment, the magnetic control component has a single adjustment method, and the maximum and minimum values ​​of the adjustment are unchanged, resulting in low applicability.

The sliding module ensures reliable and stable connection of the magnetoresistive module, effectively preventing instability caused by floating ends. Furthermore, the modular design allows for altering the resistance value by changing the number of magnetic units. These two adjustment methods significantly expand the resistance adjustment range. The locking mechanism allows for changing the radius of the magnetoresistive module; different locking blocks can be used with flywheels of varying radii. For production, this greatly improves component versatility, saves production costs, and increases economic efficiency. Attached Figure Description

[0052] Please see Figure 1 This embodiment provides an elliptical bicycle, including: a frame assembly 11, a flywheel assembly 13, a pedal assembly 15, and a resistance adjustment assembly; the frame assembly 11 includes a frame 11, a frame 11 handlebar 12, and a cover 17, with the handlebar 12 hinged to the frame 11; the flywheel assembly 13 includes a flywheel 13, rotatably connected to the frame 11, with a ferromagnetic material on its outer surface; the pedal assembly 15 includes a drive wheel 14 and a pedal 15, with the drive wheel rotatably connected to the frame 11 and the drive wheel 13 being connected to the flywheel 13 via a transmission connection; one end of the pedal 15 is hinged to the frame 11 handlebar 12, and the other end is hinged to the drive wheel 14; as shown Figure 2 As shown, the resistance adjustment assembly includes a magnetic resistance module 20, a first pull cable module 30, a second pull cable module 40, and a sliding module 50. The sliding module 50 includes a hinge seat 51, a slider 52, and a slide rail 53. The slide rail 53 is mounted on the frame 11. The slider 52 is slidably connected to the slide rail 53. The hinge seat 51 is connected to the slider 52. One end of the first pull cable module 30 is connected to the hinge seat 51, and the other end is connected to the frame 11. One end of the second pull cable module 40 is connected to the top of the magnetic resistance module 20, and the other end is connected to the frame 11. The bottom of the magnetic resistance module 20 is hinged to the hinge seat 51.

[0053] The first pull-wire module 30 and the second pull-wire module 40 control the upper and lower ends of the magnetoresistive module 20 to move closer to and further away from the flywheel 13, thereby increasing and decreasing the resistance. Compared with unilateral adjustment, this increases the resistance range. Step-by-step adjustment up and down improves adjustment accuracy, and synchronous adjustment makes the resistance change more linear. The sliding module 50 ensures a reliable and stable connection of the magnetoresistive module 20, effectively preventing stability loss due to floating at both ends.

[0054] Furthermore, such as Figures 3 to 6 As shown, the magnetoresistive module 20 includes two or more magnetoresistive units and a locking block 23. Each magnetoresistive unit includes a mounting base 21 and a magnet 22. The mounting base 21 has a mounting groove on its top, and the magnet 22 is installed in the mounting groove. The bottom sides of the mounting base 21 are hinged to adjacent magnetoresistive unit mounting bases 21. The mounting base 21 has a locking slot 2101 in the middle of both sides. The locking block 23 connects between the locking slots 2101 of two adjacent mounting bases 21. The locking block 23 has a limiting protrusion 2301 in the middle, allowing it to be locked between the mounting bases 21 to prevent slippage. The magnetoresistive module 20, through modular assembly, allows for changing the resistance value by disassembling and reassembling the number of magnetoresistive units. This two-way adjustment greatly increases the resistance adjustment range. Furthermore, the radius of the magnetoresistive module 20 can be changed by using the locking block 23. By using different locking blocks 23, it can be used with flywheels 13 of different radii. For production, this greatly improves the versatility of components, saves production costs, and increases economic efficiency.

[0055] Furthermore, the magnetoresistive module 20 also includes a first connecting plate 26 and a second connecting plate 27. The bottom of the magnetoresistive unit mounting base 21 is provided with a threaded hole. One end of the first connecting plate 26 is hinged to the hinge base 51 of the sliding module 50, and the other end is bolted to the bottom of the magnetoresistive unit mounting base 21 at the bottom of the magnetoresistive module 20. One end of the second connecting plate 27 is connected to the second pull wire module 40, and the other end is bolted. The first connecting plate 26 and the second connecting plate 27 are detachably connected by threads, which can be easily adjusted and replaced, improving the assembly processability and adjustment convenience.

[0056] Furthermore, such as Figure 7 As shown, the magnetoresistive module 20 also includes a tension rope 24 and a limiting block. The limiting block is cylindrical with threads at the bottom and a boss at the top. The magnetoresistive unit mounting base 21 has a rope nail mounting hole at the front, and the rope nail is threaded onto the magnetoresistive unit mounting base 21. The tension rope 24 is wound between the limiting blocks of the lowermost and uppermost magnetoresistive unit mounting base 21 of the magnetoresistive module 20. The tension rope 24 and the limiting block can stabilize the structure of the magnetoresistive module 20, improve the structural integrity, and prevent structural disintegration during assembly and disassembly.

[0057] Furthermore, such as Figure 8 and Figure 9 As shown, the sliding module 50 also includes a limiting plate 54, which is installed at both ends of the slide rail 53. The second cable module 40 includes a mounting plate 41, a limiting bolt 42, and a cable unit 43. The mounting plate 41 is inverted U-shaped and is connected to the frame 11. The limiting bolt 42 is bolted to the left side of the mounting plate 41, and the cable unit 43 is connected to the right side of the mounting plate 41. The limiting plate 54 and the limiting bolt 42 prevent the magnetoresistive module 20 from directly contacting the surface material of the flywheel 13.

[0058] Furthermore, when the cable unit 43 is manually operated, the elliptical vehicle also includes a resistance adjustment knob 16, which is connected to the first cable module 30 and the second cable module 40 respectively. Both the first cable module 30 and the second cable module 40 include the cable unit 43, which includes a cable, a spring, and a sleeve. The cable has an end cap that is snapped onto the magnetic resistance module 20. The spring is sleeved on the cable, with one end connected to the frame 11 and the other end connected to the magnetic resistance module 20. The sleeve is fitted over the cable. Of course, the cable unit 43 can also be electrically operated.

[0059] The first pull-wire module 30 and the second pull-wire module 40 control the upper and lower ends of the magnetoresistive module 20 to move closer to and further away from the flywheel 13, thereby increasing and decreasing the resistance. Compared with unilateral adjustment, this increases the resistance range. It can be adjusted stepwise up and down to improve the adjustment accuracy, and synchronous adjustment can make the resistance change more linear. At the same time, the magnetoresistive module 20 can change the resistance value by changing the number of magnetic units through modular splicing. Adjusting in two ways can greatly improve the resistance adjustment range. Furthermore, the radius of the magnetoresistive module 20 can be changed by setting the locking block 23. By using different locking blocks 23, it can be used with flywheels 13 of different radii. For the production end, this greatly improves the versatility of parts, saves production costs, and improves economic efficiency.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
