Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and specifically relates to a lifting drive mechanism for treadmills with noise reduction effect. Background Technology

[0002] As a core piece of equipment for modern indoor aerobic exercise, the treadmill provides users with customizable exercise scenarios through the coordinated operation of components such as the running belt, running board, drive motor, and intelligent control panel. Its core innovation lies in the integrated lifting drive mechanism, which dynamically adjusts the running board inclination angle to accurately simulate diverse terrains such as flat ground and inclines, achieving stepless switching of exercise intensity. This meets the personalized needs from basic walking to high-intensity interval training, significantly improving training adaptability and user experience.

[0003] Since the lifting drive mechanism for raising and lowering the running board is generally located below the front end of the running board, and the support bracket for the control console is mostly curved, the above configuration means that when the running board raises the running belt, the lifting drive mechanism will rise synchronously with the running board. At this time, the relative position between the bottom of the control console and the running board and running belt changes, causing the control console to block the front end of the running belt on the running board. This blockage will shorten the effective usable length of the running belt, making it impossible to carry out training modes that require more running belt space (such as sprint running and high knee training). Utility Model Content

[0004] To address the problem that the effective usable length of the running belt is shortened due to obstruction by the control panel 1 after the inclination of the running belt is adjusted, this utility model proposes a lifting drive mechanism with noise reduction effect for treadmills to overcome the above-mentioned technical problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a lifting drive mechanism for a treadmill with noise reduction effect, comprising a mounting frame, a running component disposed inside the mounting frame, a lifting component disposed between the bottom of the running component and the mounting frame, an arc-shaped support plate fixedly connected to the top of the mounting frame, a guide component disposed between the arc-shaped support plate and the running component, a control console disposed on the top of the arc-shaped support plate, and an angle adjustment component disposed between the control console and the arc-shaped support plate.

[0007] The lifting assembly is used to lift the running assembly so that the running assembly can move up and down under the guidance of the guide assembly, and the angle adjustment assembly is used to adjust the tilt of the console.

[0008] Furthermore, the running component includes a support frame disposed inside the mounting frame, and a running belt is disposed inside the support frame.

[0009] Furthermore, the lifting assembly includes a fixing plate, which is fixedly connected to the inner wall of the mounting frame. A screw is rotatably connected to one side of the fixing plate, and a push rod is threadedly connected to the outer surface of the screw. Both ends of the push rod are rotatably connected to lifting rods, and the top end of the lifting rod is rotatably connected to the bottom of the support frame.

[0010] Furthermore, a motor is fixedly installed on the bottom inner wall of the mounting frame, the output end of the motor is fixedly connected to the screw, a fixing rod is fixedly connected to one side of the fixing plate, and the push rod is movably connected to the fixing rod.

[0011] Furthermore, the guiding assembly includes an arc-shaped guide groove, which is formed on the outer side of the arc-shaped support plate. A T-shaped guide rod is movably connected inside the arc-shaped guide groove. The T-shaped guide rod is fixedly connected to the support frame. A connecting frame is fixedly connected to the bottom of the support frame. A roller is fixedly installed at the bottom of the connecting frame. A limit groove is formed on the inner wall of the mounting frame. A limit rod is movably connected inside the limit groove. The limit rod is fixedly connected to the connecting frame.

[0012] Furthermore, the angle adjustment assembly includes an adjustment column, which is rotatably connected to an arc-shaped support plate. The control console is fixedly connected to the top of the adjustment column. The adjustment column has a storage cavity inside, and a T-shaped moving rod is movably connected inside the storage cavity. One end of the T-shaped moving rod passes through the adjustment column and is fixedly connected to an I-shaped pull rod. The arc-shaped support plate has positioning holes on its outer side. Multiple positioning holes are arranged in a circumferential array. Positioning rods are inserted into the interior of several of the positioning holes. Several positioning rods are fixedly connected to the I-shaped pull rods. A spring is fixedly connected between the T-shaped moving rod and the storage cavity.

[0013] Furthermore, a silencing frame is fixedly installed on the bottom of the inner wall of the mounting frame. The silencing frame is located on the outside of the motor, with an opening on one side. Several wave-shaped silencing plates are fixedly connected to the inner wall of the silencing frame.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses a lifting component to lift the front end of the running component, allowing it to move upwards. A guide component then guides the front end of the running component. Since the curvature of the guide component matches that of the curved support plate, the front end of the running component can move upwards in an arc shape. Furthermore, the distance between the front end of the running component and the control panel remains constant, preventing the control panel from obstructing the front end of the running component. This also reduces the risk of collisions during sprinting or high knee exercises on the treadmill.

[0016] This invention uses an I-shaped moving rod to pull a T-shaped moving rod, causing several positioning rods to move out of the positioning holes. The control console is then rotated to a suitable angle using an adjusting column. After adjustment, the I-shaped pull rod is released, and a spring pulls the I-shaped pull rod via the T-shaped moving rod. Simultaneously, the positioning rods can move back into their corresponding positioning holes, thus positioning the adjusting column. This control console can be angled according to the running belt's tilt, allowing users to better view the data displayed on the control console during training.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a lifting drive mechanism with noise reduction effect for a treadmill, including a mounting frame 1, a running component 2 is arranged inside the mounting frame 1, a lifting component 3 is arranged between the bottom of the running component 2 and the mounting frame 1, an arc-shaped support plate 4 is fixedly connected to the top of the mounting frame 1, a guide component 5 is arranged between the arc-shaped support plate 4 and the running component 2, a control console 6 is arranged on the top of the arc-shaped support plate 4, and an angle adjustment component 7 is arranged between the control console 6 and the arc-shaped support plate 4.

[0030] The lifting component 3 is used to lift the running component 2 so that the running component 2 can move up and down under the guidance of the guide component 5, and the angle adjustment component 7 is used to adjust the tilt of the control console 6.

[0031] When adjusting the tilt of the running component 2, the lifting component 3 is driven directly. At this time, the lifting end of the lifting component 3 lifts the front end of the running component 2 upward, so that the front end of the running component 2 moves upward in an arc shape along the arc support plate 4 under the guidance of the guide component 5.

[0032] The lifting component 3 lifts the front end of the running component 2, causing it to move upwards. At this time, the guide component 5 guides the front end of the running component 2. Since the curvature of the guide component 5 is consistent with the curvature of the curved support plate 4, the front end of the running component 2 can move upwards in an arc shape. The distance between the front end of the running component 2 and the control panel 6 remains constant, thus avoiding the phenomenon that the control panel 6 will block the front end of the running component 2. It also makes it less likely to bump into the front end when sprinting or doing high knee training on the treadmill.

[0033] In one embodiment, the running component 2 includes a support frame 201 disposed inside the mounting frame 1, and a running belt 202 is disposed inside the support frame 201.

[0034] When running, the trainee can stand on the running belt 202. At this time, the drive device inside the support frame 201 drives the running belt 202 to rotate inside the support frame 201, so that the trainee can run as the running belt 202 moves.

[0035] In one embodiment, the lifting assembly 3 includes a fixing plate 301, which is fixedly connected to the inner wall of the mounting frame 1. A screw 302 is rotatably connected to one side of the fixing plate 301. A push rod 303 is threadedly connected to the outer surface of the screw 302. Both ends of the push rod 303 are rotatably connected to lifting rods 304. The top end of the lifting rod 304 is rotatably connected to the bottom of the support frame 201.

[0036] By rotating the screw 302, the rotating screw 302 can drive the two lifting rods 304 to move through the push rod 303. During the movement, the lifting rods 304 rotate upward continuously. At this time, the front end of the support frame 201 begins to move upward continuously under the lifting of the two lifting rods 304.

[0037] In one embodiment, for the mounting frame 1 described above, a motor 305 is fixedly installed on the bottom of the inner wall of the mounting frame 1, the output end of the motor 305 is fixedly connected to the screw 302, a fixing rod 306 is fixedly connected to one side of the fixing plate 301, and the push rod 303 is movably connected to the fixing rod 306.

[0038] The screw 302 is driven by the motor 305, so that the push rod 303 moves automatically inside the mounting frame 1 under the drive of the screw 302. During this process, the fixed rod 306 can guide the push rod 303, so that the push rod 303 is less likely to wobble when pushing the two lifting rods 304.

[0039] In one embodiment, the guide component 5 includes an arc-shaped guide groove 501, which is formed on the outer side of the arc-shaped support plate 4. A T-shaped guide rod 502 is movably connected inside the arc-shaped guide groove 501. The T-shaped guide rod 502 is fixedly connected to the support frame 201. A connecting frame 503 is fixedly connected to the bottom of the support frame 201. A roller 504 is fixedly installed at the bottom of the connecting frame 503. A limiting groove 505 is formed on the inner wall of the mounting frame 1. A limiting rod 506 is movably connected inside the limiting groove 505. The limiting rod 506 is fixedly connected to the connecting frame 503.

[0040] When the lifting rod 304 lifts the support frame 201, the limiting groove 505 can limit the rear end of the support frame 201 through the limiting rod 506, so that the roller 504 at the bottom of the support frame 201 is always in contact with the bottom of the inner wall of the mounting frame 1. Meanwhile, the front end of the support frame 201 drives the T-shaped guide rod 502 to move inside the arc-shaped guide groove 501. At this time, the arc-shaped guide groove 501 guides the trajectory of the lifting and lowering of the front end of the support frame 201 through the T-shaped guide rod 502, so that the support frame 201 can move upward in an arc shape.

[0041] In one embodiment, the angle adjustment component 7 includes an adjustment column 701, which is rotatably connected to an arc-shaped support plate 4. The control console 6 is fixedly connected to the top of the adjustment column 701. A storage cavity 702 is provided inside the adjustment column 701. A T-shaped moving rod 703 is movably connected inside the storage cavity 702. One end of the T-shaped moving rod 703 passes through the adjustment column 701 and is fixedly connected to an I-shaped pull rod 704. A positioning hole 705 is provided on the outer side of the arc-shaped support plate 4. Multiple positioning holes 705 are arranged in a circumferential array. Positioning rods 706 are inserted into the interior of several positioning holes 705. Several positioning rods 706 are fixedly connected to the I-shaped pull rods 704. A spring 707 is fixedly connected between the T-shaped moving rod 703 and the storage cavity 702.

[0042] After the inclination of the running belt 202 is adjusted, the T-shaped moving rod 703 is pulled by the I-shaped tie rod 704, which compresses the spring 707 inside the storage cavity 702. As the T-shaped moving rod 703 moves continuously inside the storage cavity 702, several positioning rods 706 can move out from inside the positioning holes 705. At this time, the adjusting column 701 between the two arc-shaped support plates 4 is rotated by the control console 6, allowing the control console 6 to adjust the angle according to the inclination of the running belt 202. When the control console 6 rotates to the appropriate position... After adjusting the angle, the I-shaped tie rod 704 is released. At this time, the spring 707 can pull the T-shaped moving rod 703, thereby causing the T-shaped moving rod 703 to drive the I-shaped tie rod 704 to reset. At the same time, several positioning rods 706 can move back into the corresponding positioning holes 705. Since the T-shaped moving rod 703 is rectangular in shape and is movably connected to the shaft of the adjusting column 701, after the positioning rods 706 complete the positioning of the T-shaped moving rod 703 through the positioning holes 705, the adjusting column 701 cannot rotate between the two arc-shaped support plates 4.

[0043] In one embodiment, for the mounting frame 1, a silencing frame 8 is fixedly installed on the bottom of the inner wall of the mounting frame 1. The silencing frame 8 is located on the outside of the motor 305. An opening is provided on one side of the silencing frame 8. A plurality of wave-shaped silencing plates 9 are fixedly connected to the inner wall of the silencing frame 8.

[0044] Both the silencing frame 8 and the wave-shaped silencing plate 9 are made of sound-absorbing material. When the motor 305 is working, most of the noise generated will be absorbed by the silencing frame 8. When the residual sound drifts out from the wave-shaped silencing plates 9, the sound will be reflected between the wave-shaped silencing plates 9 and continuously attenuated. The above arrangement ensures that the sound generated when the motor 305 is working will not be transmitted out from the inside of the silencing frame 8. At the same time, the silencing frame 8 is not completely sealed, which effectively prevents the heat generated by the motor 305 from accumulating inside the silencing frame 8.

[0045] Through the above technical solution, 1. The lifting component 3 lifts the front end of the running component 2, causing the front end of the running component 2 to move upward. At this time, the guide component 5 can guide the front end of the running component 2. Since the curvature of the guide component 5 is consistent with the curvature of the arc-shaped support plate 4, the front end of the running component 2 can move upward in an arc shape, and the distance between the front end of the running component 2 and the control panel 6 remains consistent, thus avoiding the phenomenon that the control panel 6 will block the front end of the running component 2. It also makes it less likely to bump into the front end when sprinting or high knee training on the treadmill; 2. The I-shaped tie rod 704 connects the T-shaped... Pulling the moving rod 703 causes several positioning rods 706 to move out of the positioning holes 705. At this time, the control console 6 is rotated to a suitable angle by adjusting the column 701. After the adjustment is completed, the I-shaped pull rod 704 is released. At this time, the spring 707 pulls the I-shaped pull rod 704 through the T-shaped moving rod 703. At the same time, several positioning rods 706 can move back into the corresponding positioning holes 705, thereby completing the positioning of the adjusting column 701. The control console 6 can be adjusted according to the angle of the running belt 202 after the tilt adjustment is completed, so that the user can better view the data displayed on the control console 6 during training.
