Description

Technical Field

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

[0002] An exercise bike is a fitness device that uses magnetic force to adjust resistance. It combines magnetic force with a flywheel to regulate resistance. By adjusting the distance between the magnet and the flywheel using electromagnetic force or manually, the resistance is changed, thus controlling the difficulty of the ride. This method is relatively smooth and avoids the noise and wear associated with traditional friction resistance. Furthermore, the resistance adjustment on an exercise bike is usually smoother, with almost no abrupt changes, allowing users to adjust the difficulty to suit their workout needs and suit various exercise intensities.

[0003] Chinese utility model patent CN220736073U discloses a magnetically controlled exercise bike, including a frame, a front support frame at the front end of the frame, a sliding groove inside the front support frame, a connecting rod inside the sliding groove, a sliding block outside the connecting rod, and handles mirror-mounted at both ends of the sliding block. Several locking holes are provided on the outer side of the connecting rod, and a locking component is provided on the handle. The locking component includes a movable locking block that can engage with the locking holes. By configuring the connecting rod, sliding block, and locking component, when the handle height needs to be adjusted, the locking component is opened, the locking block disengages from the locking holes on the connecting rod, and the sliding block, carrying the handle, can move. When the handle reaches the desired position, the locking component is opened again, and the locking block engages with the locking holes again, completing the locking and successfully adjusting the handle height.

[0004] The aforementioned existing technology discloses a magnetically controlled exercise bike with two fans located at the two foot pedals. When users begin exercising, the fans are turned on if needed, providing a cooling effect and simulating a natural breeze to enhance the user experience. However, the fans have a fixed airflow angle. For taller users, the airflow tends to blow towards their lower body or legs, while shorter users may experience weaker airflow, primarily concentrated on their upper body or head. This height difference can lead to varying airflow effects, affecting the cooling sensation during exercise. Therefore, we propose an exercise bike design. Utility Model Content

This allows users of different heights or exercise postures to adjust the airflow angle of the fan assembly according to their needs, ensuring that the airflow is directly directed to the parts that require the most cooling, thus improving comfort. This solves the technical problem that differences in user height can lead to varying airflow effects, affecting the cooling sensation during exercise.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-4 As shown, an exercise bike includes an exercise bike body 1, a front support frame 11 mounted on the exercise bike body 1, one side of the front support frame 11 connected to a support rod 12, the exercise bike body 1 also includes a fan assembly 2, a handlebar body 21, a fan adjustment mechanism and a handlebar adjustment mechanism; a fan assembly 2 for cooling the exerciser is rotatably mounted on one end of the support rod 12; a handlebar body 21 is mounted on the outer side of the front support frame 11; a fan adjustment mechanism is mounted on the front support frame 11 for adjusting the airflow angle of the fan assembly 2 and limiting the adjusted angle; a handlebar adjustment mechanism is also mounted on the front support frame 11 for adjusting the position of the handlebar body 21 on the front support frame 11.

[0026] Specifically, when the exercise bike body 1 is in use, the user can adjust the airflow angle of the fan assembly 2 through the airflow adjustment mechanism. This allows the fan assembly 2 to adjust the airflow angle according to the user's individual needs, ensuring that the user remains in an optimal cool state during exercise, effectively reducing discomfort caused by excessive body temperature or excessive sweating, thereby improving the sustainability and effectiveness of the workout.

[0027] Meanwhile, by adjusting the air delivery angle, the airflow generated by the fan assembly 2 can be precisely concentrated in the required area, avoiding energy waste, improving fan efficiency and enhancing energy-saving performance.

[0028] In addition, by adjusting the position of the handle body 21 on the front support frame 11 using the handle adjustment mechanism, it can help fitness enthusiasts maintain a more suitable exercise posture, avoid poor posture problems such as bending over and hunching caused by unreasonable handle position, and make the handle body 21 highly fit the height characteristics of fitness enthusiasts, thereby reducing arm fatigue and discomfort.

[0029] See Figures 1-3 and Figure 5As shown, the fan adjustment mechanism includes a rotating mechanism, a first limiting mechanism, and a transmission mechanism. The rotating mechanism is mounted on the support rod 12 and the fan assembly 2, and drives the fan assembly 2 to rotate at one end of the support rod 12. The first limiting mechanism is mounted on the support rod 12 and works in conjunction with the rotating mechanism to limit its movement. The transmission mechanism is mounted on the first limiting mechanism and drives it to operate the rotating mechanism. The rotating mechanism includes a geared disc 22 and a gear plate 23. The geared disc 22 is connected to the upper side of the fan assembly 2. The gear plate 23 is mounted on the support rod 12 and abuts against the geared disc 22. The first limiting mechanism... The first limiting mechanism includes a first screw 24, a slide plate 25, and a slide groove 26. The first screw 24 is rotatably disposed within the support rod 12. The slide plate 25 is disposed within the support rod 12 and is threadedly connected to the first screw 24. The slide groove 26 is formed on the side of the support rod 12 near the slide plate 25 and is used to cooperate with the slide plate 25 for linear movement.

[0030] Specifically, the toothed disc 22 meshes with the toothed plate 23, and the slide plate 25 is adapted to the slide groove 26. The synchronization assembly 27 is assembled from a large synchronous pulley, a synchronous belt, and a small synchronous pulley, wherein the large synchronous pulley and the small synchronous pulley mesh with the synchronous belt respectively. The large synchronous pulley is connected to one end of the first screw 24, and the small synchronous pulley is connected to one end of the crank handle 28.

[0031] When the exercise bike body 1 is put into use, the user sits on the seat and turns the crank handle 28. The rotation of the crank handle 28 causes the small synchronous pulley in the synchronization assembly 27 to rotate. Since both the large and small synchronous pulleys are engaged with the synchronous belt, the small synchronous pulley drives the large synchronous pulley to rotate through the synchronous belt, which in turn drives the first screw 24 to rotate. Because the slide plate 25 is adapted to the slide groove 26, the slide plate 25 does not rotate with the first screw 24, and the first screw 24 and the slide plate 25 are threadedly connected, so the slide plate 25 can move stably in a straight line along the slide groove 26.

[0032] The movement of the slide plate 25 drives the toothed plate 23 to move, and the toothed plate 23 engages with the toothed disc 22, thereby driving the toothed disc 22 to rotate. The rotation of the toothed disc 22 drives the fan assembly 2 to rotate, thereby adjusting the air delivery angle of the fan assembly 2. When the rotation of the handle body 21 stops, the self-locking characteristic of the thread effectively prevents the adjusted air delivery angle of the fan assembly 2 from changing.

[0033] This allows fitness enthusiasts of different heights or using different exercise postures to adjust the fan's airflow angle according to their own needs, ensuring that the airflow can directly reach the parts that need cooling the most, effectively improving comfort, reducing discomfort caused by overheating or excessive sweating, enhancing the sustainability of exercise, and improving exercise results.

[0034] See Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the handle adjustment mechanism includes a connecting cover 3, a second limiting mechanism, and an anti-jamming mechanism; the connecting cover 3 is disposed between the two handle bodies 21, and the connecting cover 3 is sleeved with the front support frame 11; the second limiting mechanism is disposed on the connecting cover 3 and the front support frame 11, and the second limiting mechanism is used to limit the position of the connecting cover 3 on the front support frame 11; the anti-jamming mechanism is disposed on the connecting cover 3, and the anti-jamming mechanism is used to prevent jamming when the connecting cover 3 moves along the front support frame 11; the second limiting mechanism includes a second screw 31, a toothed block 32, a storage groove 33, and a rack 34; the second screw 31 is threadedly connected to the connecting cover 3; the toothed block 32 is rotatably disposed at one end of the second screw 31; the receiving groove 33 is opened on the side of the connecting cover 3 near the toothed block 32, and the receiving groove 33 is used to cooperate with the toothed block 32 to move linearly and prevent the toothed block 32 from rotating and deviating when moving; the rack 34 is embedded in the side of the front support frame 11 near the toothed block 32, and the rack 34 is connected to the toothed block 32; the anti-jamming mechanism includes a groove 35 and a ball 36; the groove 35 is opened on the inner side of the connecting cover 3; the ball 36 engages with the groove 35, and the ball 36 is in contact with the outer side of the front support frame 11.

[0035] Specifically, the toothed block 32 and the storage groove 33 are adapted to each other, and the toothed block 32 meshes with the rack 34.

[0036] When the exercise bike body 1 is put into use, the user first rotates the second screw 31. Since the connecting cover 3 and the second screw 31 are connected by a thread, the rotation of the second screw 31 will cause the toothed block 32 to move in a specific direction, moving the toothed block 32 away from the rack 34. At this time, the connecting cover 3 is released from its limiting state, and the user can freely pull the handlebar body 21. During the pulling process, the handlebar body 21 causes the connecting cover 3 to slide along the outer side of the front support frame 11.

[0037] Meanwhile, the ball bearing 36 fits tightly against the outer side of the front support frame 11. This fit effectively reduces the frictional resistance between the connecting cover 3 and the front support frame 11. Due to the reduced frictional resistance, jamming is effectively avoided during the movement of the connecting cover 3, ensuring that the connecting cover 3 can smoothly move along the outer side of the front support frame 11. When adjusting the position of the connecting cover 3, the user only needs to hold the handlebars without applying additional force, which allows the user to easily adjust the position of the handlebar body 21 on the front support frame 11.

[0038] After the handlebar body 21 is adjusted, the user rotates the second screw 31 in the opposite direction. This reverse rotation of the second screw 31 pushes the toothed block 32 to slide along the storage groove 33, bringing it closer to the rack 34. Because the toothed block 32 is compatible with the storage groove 33, it remains stable while sliding along the groove, preventing wobbling and misalignment, thus ensuring stable engagement between the toothed block 32 and the rack 34. After engagement, the connecting cover 3 is confined to the outside of the front support frame 11, facilitating convenient adjustment of the handlebar body 21 of the exercise bike.

[0039] When the exercise bike body 1 is put into use, the height of the handlebar body 21 is first adjusted using the handlebar adjustment mechanism. This allows the user to maintain a more suitable posture, effectively avoiding poor posture problems such as bending over and hunching caused by improper handlebar positioning. After adjusting the handlebar height, the user can sit on the seat of the exercise bike body 1 and begin their workout. During exercise, the user will gradually sweat. At this time, the user can turn the crank handle 28, using the airflow adjustment mechanism between the crank handle 28 and the fan assembly 2 to control the rotation of the fan assembly 2, thereby adjusting the airflow angle of the fan assembly 2. This can meet the personalized needs of users of different heights and using different exercise postures, allowing them to flexibly adjust the fan's airflow angle according to their own actual situation, ensuring that the airflow is precisely directed to the parts of the body that need cooling, effectively improving comfort during exercise.

[0040] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
