Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a spinning bike. Background Technology

[0002] As people's living standards continue to improve, more and more people are paying attention to their physical fitness, and as a result, the number of people engaging in fitness activities is constantly expanding. Indoor exercise bikes are fitness equipment placed indoors for exercise. Unlike ordinary bicycles, users don't move around as much when riding an indoor bike, so they are not limited by location and can effectively mimic outdoor cycling. Therefore, they have become popular rapidly and are loved by the general public.

[0003] Traditional exercise bikes typically consist of a frame, flywheel, and pedals. Due to the flywheel, the frame is usually quite large to ensure stability at high speeds, taking up considerable space and making them bulky and inconvenient to move. Some exercise bikes fix the flywheel to the handlebar strut via a connecting arm, resulting in a more compact structure and reduced space usage. However, since the flywheel is suspended and relies solely on the connecting arm for support, the bike's stability is poor at high speeds, affecting the riding experience. Furthermore, the control system on exercise bikes requires a power source, necessitating frequent battery charging, which is quite inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a compact and stable exercise bike.

[0005] The technical solution of this utility model is to provide a stationary bicycle with the following structure: including a frame and handlebars, a seat, a flywheel, pedals, and a resistance adjustment assembly mounted on the frame; the frame includes a base, a first support, a second support, a third support, and a crossbar; the first support is vertically mounted at one end of the base, the second support is mounted at the other end of the base and is inclined away from the first support, the third support is mounted at the lower end of the second support and is inclined towards the first support; the crossbar is positioned between the first and second supports, and its two ends are connected to the first and second supports respectively; the handlebars are mounted at the upper end of the third support, the seat is mounted at the upper end of the second support, the flywheel is rotatably connected to the first support, the pedals are mounted at the connection between the second and third supports and are connected to the flywheel for driving the flywheel to rotate, and the resistance adjustment assembly is mounted on the crossbar for adjusting the resistance of the flywheel.

[0006] By adopting the above structure, the exercise bike of this invention has the following advantages compared with the prior art:

[0007] The frame is configured as a base, a first support, a second support, a third support, and a crossbar. The first support is tilted away from the first support, and the third support is tilted towards the first support, so that the space below the third support can accommodate the flywheel. This makes the overall structure of the exercise bike more compact and reduces its space occupation. The flywheel is connected to the first support, which is fixed to the base and connected to the second support through the crossbar. This makes the overall structure of the exercise bike more stable, avoids frame vibration caused by the high-speed rotation of the flywheel, and improves the user's riding experience.

[0008] Preferably, the frame is also equipped with a generator, which is connected to the flywheel via a belt drive to charge the battery on the exercise bike. When the user is riding, the flywheel drives the generator to generate electricity, which in turn charges the battery on the exercise bike, meeting the bike's power needs without requiring the user to charge it separately, saving time and effort.

[0009] Preferably, the second bracket has a first sliding cavity with an opening at the top, and a first telescopic frame is slidably connected within the first sliding cavity. The upper end of the first telescopic frame extends outside the first sliding cavity and connects to the bottom of the seat. The second bracket has a first locking bolt for locking the position of the first telescopic frame within the first sliding cavity. The third bracket has a second sliding cavity with an opening at the top, and a second telescopic frame is slidably connected within the second sliding cavity. The upper end of the second telescopic frame extends outside the second sliding cavity and connects to the bottom of the handlebars. The third bracket has a second locking bolt for locking the position of the second telescopic frame within the second sliding cavity. With this configuration, the user can adjust the height of the handlebars and seat according to their needs. Since the second and third brackets are tilted, the distance between them can also be adjusted while adjusting the height of the handlebars and seat.

[0010] Preferably, the top of the first telescopic frame is connected to a first slide rail extending horizontally, and the bottom of the seat is provided with a first slider, which is slidably connected to the first slide rail. A third locking bolt is provided at the bottom of the first slide rail to lock the first slider onto the first slide rail. Similarly, the top of the second telescopic frame is connected to a second slide rail extending horizontally, and the bottom of the handlebars is provided with a second slider, which is slidably connected to the second slide rail. A fourth locking bolt is provided at the bottom of the second slide rail to lock the second slider onto the second slide rail. Since the distance between the handlebars and seat is adjusted simultaneously with the height of the handlebars and seat, users with unusual limb lengths can adjust the distance between the handlebars and seat individually to meet the needs of all users.

[0011] Preferably, the third bracket is also equipped with a brake assembly, which includes a brake lever and a brake pad. The brake lever is rotatably connected to the third bracket. A support seat is provided on the side wall of the third bracket facing the flywheel, and the middle part of the brake pad is rotatably connected to the support seat. One end of the brake pad is connected to the third bracket via a first spring, and the other end is connected to the outer peripheral wall of the brake lever via a brake cable. Rotating the brake lever causes the brake pad to contact or separate from the flywheel. The third bracket is also equipped with a locking pin for locking the brake lever, thus separating the brake pad from the flywheel. During normal riding, the locking pin locks the brake lever, separating the brake pad from the flywheel. When the user needs to brake, simply pull out the locking pin; under the force of the first spring, the other end of the brake pad will contact the flywheel, thereby stopping the flywheel.

[0012] Preferably, the pedal assembly includes a pedal, a drive wheel, and a crank connecting the pedal and the drive wheel, wherein the drive wheel is connected to a flywheel via a belt.

[0013] Preferably, the resistance adjustment assembly includes a magnet bracket, a stepper motor, and a control knob. Several magnets are evenly distributed on the magnet bracket. The magnet bracket is rotatably connected to a third bracket. The stepper motor is fixedly connected to a crossbar. The free end of the magnet bracket is connected to the output end of the stepper motor via a steel wire rope. The control knob is located on the handlebars and electrically connected to the stepper motor, used to control the stepper motor to move the free end of the magnet bracket closer to or further away from the flywheel, thereby adjusting the distance between the magnet and the flywheel.

[0014] The control knob controls the output of the stepper motor. The stepper motor pulls the free end of the magnet bracket. When the magnet on the magnet bracket approaches the flywheel, the magnetic resistance of the flywheel increases. When the magnet on the magnet bracket moves away from the flywheel, the magnetic resistance of the flywheel decreases.

[0015] Preferably, the resistance adjustment assembly further includes a spring seat and a second spring. The spring seat is fixedly connected to the crossbar, and the second spring is disposed inside the spring seat, with one end abutting against the spring seat and the other end abutting against the free end of the magnet bracket. The second spring can prevent the magnetic force from being too low to reset when the magnet on the magnet bracket is too far from the flywheel. Attached Figure Description

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown;

[0026] This utility model discloses a stationary bicycle: including a frame 1 and handlebars 2, seat 3, flywheel 4, pedal assembly 5 and resistance adjustment assembly 6 mounted on the frame 1.

[0027] The frame 1 includes a base 11, a first support 12, a second support 13, a third support 14, and a crossbar 15. The first support 12 is vertically mounted at one end of the base 11, the second support 13 is mounted at the other end of the base 11 and is inclined away from the first support 12, the third support 14 is mounted at the lower end of the second support 13 and is inclined towards the first support 12, and the crossbar 15 is positioned between the first support 12 and the second support 13, with both ends connected to the first support 12 and the second support 13 respectively. The handlebar 2 is mounted on the upper end of the third support 14, the seat 3 is mounted on the upper end of the second support 13, the freewheel 4 is rotatably connected to the first support 12, the pedal assembly 5 is located at the connection between the second support 13 and the third support 14 and is connected to the freewheel 4 for driving the freewheel 4 to rotate, and the resistance adjustment assembly 6 is mounted on the crossbar 15 for adjusting the resistance of the freewheel 4.

[0028] The frame 1 is configured as a base 11, a first support 12, a second support 13, a third support 14 and a crossbar 15, with the first support 12 tilted away from the first support 12 and the third support 14 tilted towards the first support 12, so that the flywheel 4 can be accommodated at the position below the third support 14. This makes the overall structure of the exercise bike more compact and reduces the space it occupies.

[0029] The flywheel 4 is connected to the first bracket 12, which is fixed to the base 11 and connected to the second bracket 13 via the crossbar 15. This makes the overall structure of the exercise bike more stable, avoids vibration of the frame 1 caused by the high-speed rotation of the flywheel 4, and improves the user's riding experience.

[0030] The frame 1 is also equipped with a generator 7, which is connected to the flywheel 4 via a belt drive to charge the battery on the exercise bike. When the user is riding, the flywheel 4 drives the generator 7 to generate electricity, which charges the battery on the exercise bike, meeting the bike's power needs without requiring the user to charge it separately, saving time and effort.

[0031] The second bracket 13 is provided with a first sliding cavity 131 with an opening at the top. A first telescopic frame 132 is slidably connected in the first sliding cavity 131. The upper end of the first telescopic frame 132 extends to the outside of the first sliding cavity 131 and is connected to the bottom of the seat 3. The second bracket 13 is provided with a first locking bolt 133. The connecting end of the first locking bolt 133 passes through the screw hole on the second bracket 13 and abuts against the outer peripheral wall of the first telescopic frame 132 to lock the position of the first telescopic frame 132 in the first sliding cavity 131. The outer peripheral wall of the first telescopic frame 132 is also provided with several grooves spaced apart along its length to allow the connecting end of the first locking bolt 133 to be inserted, thereby better preventing the first telescopic frame 132 from sliding in the first sliding cavity 131.

[0032] The third bracket 14 is provided with a second sliding cavity 141 with an opening at the top. A second telescopic frame 142 is slidably connected in the second sliding cavity 141. The upper end of the second telescopic frame 142 extends to the outside of the second sliding cavity 141 and is connected to the bottom of the handlebar 2. The third bracket 14 is provided with a second locking bolt 143. The connecting end of the second locking bolt 143 passes through the screw hole on the third bracket 14 and abuts against the outer peripheral wall of the second telescopic frame 142 to lock the position of the second telescopic frame 142 in the second sliding cavity 141. The outer peripheral wall of the second telescopic frame 142 is also provided with several grooves distributed at intervals along its length to allow the connecting end of the second locking bolt 143 to be inserted, thereby better preventing the second telescopic frame 142 from sliding in the second sliding cavity 141.

[0033] With this setup, users can adjust the position of the first telescopic bracket 132 in the first sliding cavity 131 and the position of the second telescopic bracket 142 in the second sliding cavity 141 according to their own needs, thereby adjusting the height of the handlebars 2 and the seat 3. Since the second bracket 13 and the third bracket 14 are tilted, the distance between the two can also be adjusted while adjusting the height of the handlebars 2 and the seat 3.

[0034] The top of the first telescopic frame 132 is connected to a first slide rail 134 extending horizontally. The bottom of the seat 3 is provided with a first slider 31, which is slidably connected to the first slide rail 134. The bottom of the first slide rail 134 is provided with a third locking bolt 135. The connecting end of the third locking bolt 135 passes through the through hole on the first slide rail 134 and is threadedly connected to the elongated hole on the first slider 31 to lock the first slider 31 onto the first slide rail 134. The top of the second telescopic frame 142 is connected to a second slide rail 144 extending horizontally. The bottom of the handlebar 2 is provided with a second slider 21, which is slidably connected to the second slide rail 144. The bottom of the second slide rail 144 is provided with a fourth locking bolt 145, which is connected in the same way as the third locking bolt 135. Its purpose is to lock the second slider 21 onto the second slide rail 144.

[0035] Since the distance between the handlebars 2 and the seat 3 is adjusted simultaneously when the height of the handlebars 2 and the seat 3 is adjusted, users with special limb lengths can adjust the distance between the handlebars 2 and the seat 3 individually according to their specific circumstances to meet the needs of all users.

[0036] The third bracket 14 is also equipped with a brake assembly 8, which includes a brake lever 81 and a brake pad 82. The brake lever 81 is rotatably connected to the third bracket 14. A support seat 83 is provided on the side wall of the third bracket 14 facing the flywheel 4. The middle part of the brake pad 82 is rotatably connected to the support seat 83. One end of the brake pad 82 is connected to the third bracket 14 through a first spring 84, and the other end is connected to the outer peripheral wall of the brake lever 81 through a brake cable 85. By turning the brake lever 81, the brake pad 82 can be made to contact or separate from the flywheel 4. The third bracket 14 is also equipped with a locking pin 86 for locking the brake lever 81, so that the brake pad 82 is in a separated state from the flywheel 4.

[0037] When the user is riding normally, the locking pin 86 locks the brake lever 81. At this time, the brake pad 82 is separated from the flywheel 4. When the user needs to brake, he / she only needs to pull out the locking pin 86. Under the elastic force of the first spring 84, the other end of the brake pad 82 will contact the flywheel 4, thereby stopping the flywheel 4.

[0038] The pedal assembly 5 includes a pedal 51, a drive wheel 52, and a crank 53 connecting the pedal 51 and the drive wheel 52. The drive wheel 52 is connected to the flywheel 4 via a belt. The pedal 51 is also equipped with a foot cover to prevent the foot from slipping off the pedal 51 while riding.

[0039] The resistance adjustment assembly 6 includes a magnet bracket 61, a stepper motor 62, and a control knob 63. Several magnets are evenly distributed on the magnet bracket 61. The magnet bracket 61 is rotatably connected to the third bracket 14. The stepper motor 62 is fixedly connected to the crossbar 15. The free end of the magnet bracket 61 is connected to the output wheel of the stepper motor 62 through a steel wire rope 64. The control knob 63 is located on the handlebar 2 and is electrically connected to the stepper motor 62. It is used to control the stepper motor 62 to drive the free end of the magnet bracket 61 closer to or further away from the flywheel 4, thereby adjusting the distance between the magnet and the flywheel 4.

[0040] The control knob 63 can control the output of the stepper motor 62. The stepper motor 62 pulls the free end of the magnet bracket 61. When the magnet on the magnet bracket 61 is close to the flywheel 4, the magnetic resistance of the flywheel 4 will increase. When the magnet on the magnet bracket 61 is far away from the flywheel 4, the magnetic resistance of the flywheel 4 will decrease.

[0041] The resistance adjustment assembly 6 also includes a spring seat 64 and a second spring 65. The spring seat 64 is fixedly connected to the crossbar 15, and the second spring 65 is disposed inside the spring seat 64, with one end abutting against the spring seat 64 and the other end abutting against the free end of the magnet bracket 61. When the magnet on the magnet bracket 61 is too far from the flywheel 4, the magnetic force will decrease. To prevent the magnet bracket 61 from failing to reset due to insufficient magnetic force, a second spring 65 is provided between the magnet bracket 61 and the spring seat 64. When the stepper motor 62 pulls the wire rope 64 to move the free end of the magnet bracket 61 away from the flywheel 4, the second spring 65 is compressed. When the stepper motor 62 releases the wire rope 64, the magnet can automatically reset from the flywheel 4 under the elastic force of the second spring 65.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
