Description

Technical Field

[0001] This utility model belongs to the field of exercise bike technology, and in particular relates to a recumbent exercise bike. Background Technology

[0002] Traditional recumbent exercise bikes are typically designed with fixed resistance levels, making it impossible to flexibly adjust to individual user needs and physical conditions. This fixed resistance design limits the use of exercise bikes. For example, for beginners or users with weaker stamina, the fixed, high resistance may make them feel too strained in the early stages of exercise, making it difficult to maintain a long workout, and may even lead to resistance due to excessive fatigue, affecting the sustainability and effectiveness of the workout. Conversely, for experienced fitness enthusiasts or users with good physical fitness, the fixed, low resistance may not meet their training needs, failing to effectively stimulate muscle growth and improve cardiovascular function, resulting in poor training results. Therefore, a recumbent exercise bike has been proposed to address this issue. Utility Model Content

[0003] The purpose of this invention is to provide a recumbent exercise bike that, by incorporating a compression component, allows the user to adjust the resistance of the rotating shaft as needed during training. Activating the electric push rod moves the telescopic rod, which in turn moves the push plate and compression rod synchronously. By controlling the engagement or disengagement of the compression rod with the annular groove, the frictional force on the conical rotating column is adjusted, thereby changing the rotational resistance of the drive gear, driven gear, and rotating shaft. This solves the problem that traditional recumbent exercise bikes typically have fixed resistance, making it impossible to flexibly adjust according to the user's individual needs and physical condition. This fixed resistance design limits the use of the exercise bike.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a recumbent exercise bike, including a support crossbar. Supporting longitudinal bars are installed on both the left and right sides of the support crossbar. The support crossbar and the two supporting longitudinal bars provide a stable foundation for the overall equipment. It also includes:

[0006] An adjustment mechanism is provided above the support crossbar and is used to adjust different aspects of the user's workout.

[0007] The adjusting mechanism includes a pressing component, which includes a conical rotating column, and a pressing rod is provided on the outside of the conical rotating column.

[0008] Furthermore, each of the two support longitudinal bars is equipped with two movable wheels, a support box is welded to the left side of the top of the support crossbar, a seat is welded to the right side of the top of the support crossbar, and a hand handle is installed on the top of the support box.

[0009] The handheld stick has a control panel mounted on its surface.

[0010] Furthermore, the adjustment mechanism also includes a training component connected to the support housing, the training component being used by the user to perform simulated cycling exercises; and

[0011] An adjustment component is connected to a handheld lever and is used to adjust the sitting posture during use.

[0012] The output end of the training component is connected to the extrusion component.

[0013] Furthermore, the training component includes two foot pedals, with a rotating shaft welded inside each foot pedal. Support frames are welded to both the front and back of the outer surface of the rotating shaft. The outer rings of the two support frames are rotatably connected to the front and back of the support box. A drive gear is provided on the back of the support frame located on the front side. The drive gear is welded to the outer surface of the rotating shaft. A driven gear is provided on the back of the drive gear, and the driven gear is rotatably connected to the outer surface of the rotating shaft.

[0014] Furthermore, a bevel gear is meshed with the corresponding side of the drive gear and the driven gear, and a rotating rod is welded inside the bevel gear. The outer surface of the rotating rod is rotatably connected to the inside of the support box. The corresponding side of the drive gear and the driven gear are both provided with an arc-shaped convex surface.

[0015] Among them, the two arc-shaped convex surfaces are convex surfaces on the side away from the driving gear disk and the driven gear disk, respectively.

[0016] Furthermore, the adjustment assembly includes a movable frame, with a slide rail slidably connected inside the movable frame. The slide rail is located at the top of the seat, and several through holes are formed inside the slide rail. A fastening bolt is inserted into the movable frame, penetrating the movable frame and extending into the through holes. The outer surface of the fastening bolt is threadedly connected to the inside of each through hole. A seat cushion is installed on the top of the movable frame, and a lumbar support is provided on the right side of the seat cushion. A rotating rod is located at the top of the right side inside the movable frame, and the rotating rod is threadedly connected to the movable frame via a second fastening bolt. The rotating rod contacts a mounting block on the right side of the lumbar support, and several through holes are formed inside the mounting block. A third fastening bolt is inserted into the rotating rod, penetrating the rotating rod and extending into the through holes. The outer surface of the third fastening bolt is threadedly connected to the inside of each of the through holes.

[0017] Furthermore, a support rod is rotatably connected inside the conical rotating column. The side of the support rod away from the conical rotating column is welded to the inner wall of the support box. An electric push rod is installed on the outer surface of the support rod. A telescopic rod is connected to the right output end of the electric push rod. A push plate is welded to the side of the telescopic rod away from the electric push rod. The side of the push plate close to the electric push rod is welded to the side of the extrusion rod away from the conical rotating column. An annular groove is formed at the top of the outer surface of the conical rotating column. The inner wall of the annular groove is in contact with the side of the extrusion rod away from the push plate.

[0018] The conical rotating column is wider at the top and narrower at the bottom, and the conical surface of the conical rotating column contacts the corresponding side of the two arc-shaped convex surfaces.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting up a squeezing component, allows users to adjust the resistance of the rotating shaft as needed during training. Activating the electric push rod drives the telescopic rod to move, which in turn pushes the push plate and squeezing rod to move synchronously. By controlling the contact or disengagement of the squeezing rod with the annular groove, the frictional force on the conical rotating column is adjusted, thereby changing the rotational resistance of the drive gear plate, driven gear plate, and rotating shaft. This reduces negative emotions caused by fatigue in beginners and also reduces the inability to satisfy experienced fitness enthusiasts, thus improving training effectiveness and precisely adapting to different needs.

[0021] 2. This utility model, through the setting of adjustment components, allows users to adjust the seat and lumbar support of the recumbent exercise bike according to their own height and leg length. When adjusting the seat, rotate the first fastening bolt to make the moving frame slide on the slide rail. After adjusting to the appropriate position, tighten the first fastening bolt, and its convex edge contacts and presses against the moving frame. To adjust the lumbar support angle, first loosen the second fastening bolt, swing the rotating rod to drive the lumbar support to move. After adjusting, tighten the second fastening bolt. To adjust the lumbar support height, loosen the third fastening bolt, and the right support block of the lumbar support slides inside the rotating rod. After adjusting the height, tighten the third fastening bolt, and its convex edge fits against the rotating rod. Through these adjustments, user comfort and equipment versatility are improved, and the risk of exercise injury is reduced.

[0040] Adjustment component 22 includes a movable frame 221, with a slide rail 222 slidably connected inside the movable frame 221. The slide rail 222 is located on the top of the seat 116. Several through holes 223 are formed inside the slide rail 222. Fastening bolts 224 are inserted into the movable frame 221, penetrating the movable frame 221 and extending into the through holes 223. The outer surfaces of the fastening bolts 224 are threaded into the through holes 223. A seat cushion 225 is mounted on the top of the movable frame 221.

Through these adjustments, user comfort and equipment versatility are improved, and the risk of exercise injury is reduced.

[0041] A support rod 232 is rotatably connected inside the conical rotating column 231. The side of the support rod 232 away from the conical rotating column 231 is welded to the inner wall of the support box 114. An electric push rod 233 is installed on the outer surface of the support rod 232. A telescopic rod 234 is connected to the right output end of the electric push rod 233. A push plate 235 is welded to the side of the telescopic rod 234 away from the electric push rod 233. The side of the push plate 235 near the electric push rod 233 is welded to the side of the extrusion rod 236 away from the conical rotating column 231. An annular groove 237 is formed at the top of the outer surface of the conical rotating column 231. The inner wall of the annular groove 237 contacts the side of the extrusion rod 236 away from the push plate 235. With a design that is wider at the top and narrower at the bottom, the conical surface of the tapered rotating column 231 contacts the corresponding side of the two arc-shaped convex surfaces 218. During training, the user can adjust the resistance of the rotating shaft 212 as needed, activate the electric push rod 233 to drive the telescopic rod 234 to move, which pushes the push plate 235 and the squeezing rod 236 to move synchronously. By controlling the contact or disengagement of the squeezing rod 236 with the annular groove 237, the friction force on the tapered rotating column 231 is adjusted, thereby changing the rotational resistance of the drive gear plate 214, the driven gear plate 215 and the rotating shaft 212. This reduces the negative emotions caused by fatigue for beginners, and also reduces the inability to satisfy experienced fitness enthusiasts, thereby improving the training effect and accurately adapting to different needs.

[0042] One specific application of this embodiment is as follows: In use, the user first adjusts the position of the seat cushion 225 according to their height and leg length. Specifically, this is done by rotating the fastening bolt 224 to disengage it from the through hole 223. At this time, the user can adjust the movable frame 221 left and right. During the movement of the movable frame 221, it will slide on the outer surface of the slide rail 222. When the movable frame 221 is adjusted to the appropriate position, the user rotates the fastening bolt 224 to re-insert it into the through hole 223. Simultaneously, the outer surface of the fastening bolt 224 is threaded into the through hole 223. When the fastening bolt 224 is tightened, its front convex edge will make close contact and pressure with the front of the movable frame 221. Subsequently, the user can adjust the angle of the lumbar support 226 according to their comfort. First, the user can loosen it by rotating the fastening bolt 227. Then, the user can swing the rotating rod 228 left and right. During the exercise, the lumbar support 226 will move along with the lumbar support 226. When the lumbar support 226 is adjusted to a suitable angle, tighten the second fastening bolt 227. At the same time, rotate the third fastening bolt 229 to disengage it from the through hole 220. At this time, the lumbar support 226 can be adjusted up and down. During the adjustment of the lumbar support 226, its right support block will slide inside the rotating rod 228. When the lumbar support 226 is adjusted to a suitable height, tighten the third fastening bolt 229. Similarly, the outer surface of the third fastening bolt 229 is threadedly connected to the inside of the through hole 220. When the third fastening bolt 229 is tightened, its front convex edge will fit tightly against the front of the rotating rod 228. By adjusting the seat cushion 225 and the lumbar support 226 at multiple angles, it can accommodate users of different heights, thereby improving the user's comfort and the versatility of the equipment, and reducing accidental injuries caused by uncomfortable sitting posture during exercise.

[0043] Subsequently, the user alternately steps on the moving frame 221, causing the rotating shaft 212 to rotate. During this rotation, the supporting frame 213 moves along with it, rotating inside the supporting housing 114. The supporting frame 213 provides support for the rotating shaft 212. The rotation of the rotating shaft 212 also drives the drive gear 214 to rotate, which in turn drives the bevel gear 216. The rotation of the bevel gear 216 then drives the rotating shaft 212 to rotate. The rod 217 rotates inside the support housing 114, providing support for the bevel gear 216. Simultaneously, the rotation of the bevel gear 216 drives the driven gear 215 to rotate, causing it to rotate on the outer surface of the shaft 212. During the rotation of the driving gear 214 and the driven gear 215, the arc-shaped convex surface 218 drives the conical rotating column 231 to rotate. The conical rotating column 231 then rotates on the outer surface of the support rod 232, thus simulating cycling. During fitness training, users can adjust the resistance of the rotating shaft 212 according to their needs. Specifically, activating the electric push rod 233 moves the telescopic rod 234, which in turn moves the push plate 235. The push plate 235 then moves the squeezing rod 236, which engages and disengages with the annular groove 237. Adjusting the friction between the squeezing rod 236 and the conical rotating column 231 adjusts the resistance of the drive gear 214 and driven gear 215, thus adjusting the resistance of the rotating shaft 212. This adjustment allows for precise adaptation to different fitness needs. Lower resistance simulates the feeling of riding easily on a flat road, while increased resistance mimics climbing a hill or riding against the wind. This simulation of real-world scenarios increases the fun of fitness, making users feel as if they are in different riding environments, thus bringing indoor fitness closer to the experience of outdoor cycling.
