Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and specifically relates to a shock-absorbing structure for a noise-reducing lifting drive motor of a treadmill. Background Technology

[0002] In modern society, with the increasing awareness of health, treadmills, as a convenient and practical fitness equipment, are being used more and more widely in homes and gyms. The height adjustment function of treadmills is one of its important features, which can meet the personalized needs of different users for running height, and the height adjustment drive motor is the core component to realize this function.

[0003] During treadmill operation, the drive motor provides power to the lifting mechanism through the transmission components, enabling height adjustment of the front end of the track. When the front end of the track is lifted by the lifting mechanism, this area mainly relies on the lifting mechanism for rigid support. At this time, if the user runs on the track, the dynamic load generated by the impact of the footsteps will cause high-frequency vibration of the track. Since the lifting mechanism and the drive motor are rigidly connected, these vibration forces will be directly transmitted to the drive motor along the transmission path. When the drive motor is subjected to such vibration and impact for a long time, its internal precision components such as bearings and windings are prone to wear, loosening and other failures, which will lead to a decline in motor performance or even complete damage, significantly shortening its normal service life. Utility Model Content

[0004] To address the issue that vibrations generated by the running track are transmitted to the drive motor, this invention proposes a vibration damping structure for the noise reduction and lifting drive motor of a treadmill, in order to overcome the aforementioned 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: This utility model relates to a shock-absorbing structure for a noise-reducing lifting drive motor of a treadmill, comprising a support frame, an internal running track, a lifting assembly at the bottom of the running track, an elastic fixing assembly at the connection between the lifting assembly and the running track, a detachable drive assembly at the bottom of the inner wall of the support frame, the drive end of the detachable drive assembly being sleeved on the drive end of the elastic fixing assembly, and a traction assembly on the outer side of the detachable drive assembly, the traction end of the traction assembly being connected to the elastic fixing assembly. By moving the separable drive assembly to separate it from the lifting assembly, the traction assembly pulls the elastic fixing assembly under the drive of the separable drive assembly, thereby fixing the elastic fixing assembly to the front end of the runway.

[0006] Furthermore, the lifting assembly includes a fixed plate, which is fixedly connected to the bottom of the inner wall of the support frame. A screw is rotatably connected to one side of the fixed plate, and a push plate is threadedly connected to the outer surface of the screw. Rotating plates are rotatably connected to both sides of the push plate, and one end of the rotating plate is located at the bottom of the track.

[0007] Furthermore, a limiting rod is fixedly connected to one side of the fixed plate, the limiting rod is movably connected to the push plate, a guide groove is provided on the inner wall of the support frame, a guide tube is movably connected inside the guide groove, the guide tube is fixedly connected to the runway, one end of the guide tube extends to the bottom of the runway, and the rotating plate is rotatably connected to the guide tube.

[0008] Furthermore, the elastic fixing component includes a mounting frame, which is fixedly connected to the bottom of the runway. A fixing rod is movably connected inside the mounting frame, one end of which passes through the mounting frame and extends into the interior of the guide tube. Several fixing holes are provided on the inner wall of the guide groove.

[0009] Furthermore, a support rod is fixedly connected to the top of the mounting frame, and an L-shaped push plate is movably connected to the outer surface of the support rod. An inclined push groove is provided on one side of the L-shaped push plate, and a push rod is movably connected inside the inclined push groove. The push rod is fixedly connected to the fixed rod. A spring is fixedly connected between the top of the L-shaped push plate and the top of the inner wall of the mounting frame, and a connecting plate is fixedly connected to the bottom of the support rod.

[0010] Furthermore, the separable drive assembly includes a hydraulic cylinder, which is fixedly installed on the bottom of the inner wall of the support frame. The output end of the hydraulic cylinder is fixedly connected to a storage frame. A motor is fixedly connected inside the storage frame. A sleeve is fixedly connected to the output end of the motor. One end of the sleeve extends to the outside of the storage frame. A connecting rod is sleeved inside the sleeve. The connecting rod is fixedly connected to a screw. One end of the limiting rod passes through the fixing plate and is movably connected to the storage frame.

[0011] Furthermore, the traction assembly includes a storage tube, which is fixedly installed on the top of the fixed plate. A rotating shaft is rotatably connected inside the storage tube. One end of the rotating shaft passes through the storage tube and is fixedly connected to a winding reel. A traction rope is provided on the outside of the winding reel. A wire hole is opened on the top of the connecting plate. The traction rope is fixedly connected to the bottom of the L-shaped push plate through the wire hole. A spiral spring is fixedly connected between the rotating shaft and the inner wall of the storage tube.

[0012] Furthermore, the other end of the rotating shaft passes through the storage tube and is fixedly connected to a gear, and a gear frame is fixedly installed on the outside of the storage frame, with the gear frame corresponding vertically to the gear.

[0013] Furthermore, several bent sound-absorbing panels are fixedly connected to the opening of the storage frame.

[0014] This utility model has the following beneficial effects: This invention separates the detachable drive component from the lifting component by moving the detachable drive component backward. During this process, the traction component, driven by the detachable drive component, can pull the elastic fixing component through the traction end, thus fixing the front end of the track. This design prevents the vibration force generated by the track from being transmitted to the detachable drive component when the user is running on the track, thereby avoiding damage to the detachable drive component due to vibration and extending its service life.

[0015] When the storage frame is moved backward by the hydraulic cylinder, the moving storage frame can move out of the sleeve from the outside of the sleeve. The gear frame meshes with the gear under the drive of the storage frame. As the storage frame moves continuously, the gear drives the winding reel to rotate through the rotating shaft, and the winding reel winds up the traction rope. At this time, the L-shaped push plate moves downward continuously under the pull of the traction rope. The moving L-shaped push plate can push the fixing rod into the fixing hole through the inclined push groove and push rod. The above configuration can complete the separation and fixing operations at the same time as long as the storage frame is moved. At the same time, when the motor and sleeve no longer limit the rotating plate through the sleeve and screw, the track will not suddenly drop under the fixing rod and fixing hole.

[0016] 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

[0021] 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.

[0022] 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.

[0023] Please see Figures 1-8As shown, this utility model is a shock-absorbing structure for a noise-reducing lifting drive motor of a treadmill, including a support frame 1, a running track 2 inside the support frame 1, a lifting component 3 at the bottom of the running track 2, an elastic fixing component 4 at the connection between the lifting component 3 and the running track 2, a detachable drive component 5 at the bottom of the inner wall of the support frame 1, the drive end of the detachable drive component 5 being sleeved on the drive end of the elastic fixing component 4, and a traction component 6 on the outside of the detachable drive component 5, the traction end of the traction component 6 being connected to the elastic fixing component 4. By moving the separable drive component 5, the separable drive component 5 is separated from the lifting component 3. At the same time, the traction component 6 is pulled by the separable drive component 5 to pull the elastic fixing component 4 so that the elastic fixing component 4 fixes the front end of the runway 2.

[0024] The lifting assembly 3 is driven by the separable drive assembly 5, which lifts the front end of the runway 2. When the inclination of the runway 2 is adjusted appropriately, the separable drive assembly 5 moves backward. At the same time, the separable drive assembly 5 can drive the winding end of the traction assembly 6 to rotate and start winding the traction end. At this time, the elastic fixing assembly 4 can fix the front end of the runway under the pull of the traction end. When the separable drive assembly 5 is separated from the lifting assembly 3, the elastic fixing assembly 4 also completes the fixation of the runway 2.

[0025] By moving the separable drive component 5 backward, the separable drive component 5 is separated from the lifting component 3. During this process, the traction component 6, driven by the separable drive component 5, can pull the elastic fixing component 4 through the traction end, and the elastic fixing component 4 can fix the front end of the track 2. The above settings prevent the vibration force generated by the track 2 when the user is running on the track 2 from being transmitted to the separable drive component 5, thereby avoiding damage to the separable drive component 5 due to vibration, and also improving the service life of the separable drive component 5.

[0026] In one embodiment, the lifting assembly 3 includes a fixed plate 301, which is fixedly connected to the bottom of the inner wall of the support frame 1. A screw 302 is rotatably connected to one side of the fixed plate 301, and a push plate 303 is threadedly connected to the outer surface of the screw 302. A rotating plate 304 is rotatably connected to both sides of the push plate 303, and one end of the rotating plate 304 is located at the bottom of the runway 2.

[0027] By rotating the screw 302, the rotating screw 302 can drive the push plate 303 to move at the bottom of the inner wall of the support frame 1. The moving push plate 303 then pushes the rotating plate 304, causing the rotating plate 304 to rotate upward and lift the front end of the runway 2, so that the runway 2 can tilt inside the support frame 1.

[0028] In one embodiment, for the aforementioned fixed plate 301, a limiting rod 305 is fixedly connected to one side of the fixed plate 301, the limiting rod 305 is movably connected to the push plate 303, a guide groove 306 is provided on the inner wall of the support frame 1, a guide tube 307 is movably connected inside the guide groove 306, the guide tube 307 is fixedly connected to the runway 2, one end of the guide tube 307 extends to the bottom of the runway 2, and the rotating plate 304 is rotatably connected to the guide tube 307.

[0029] When the push plate 303 moves, the limit rod 305 can limit and guide the push plate 303, thereby ensuring the stability of the push plate 303 when pushing the two rotating plates 304; the rotating plate can lift the front end of the runway 2 through the guide tube 307. When the front end of the runway 2 moves upward, the guide tube 307 can move inside the guide groove 306. At this time, the guide groove 306 can guide the runway 2 through the guide tube 307, thereby ensuring the overall stability of the runway 2 when adjusting its tilt.

[0030] In one embodiment, the elastic fixing component 4 includes a mounting frame 401, which is fixedly connected to the bottom of the runway 2. A fixing rod 402 is movably connected inside the mounting frame 401. One end of the fixing rod 402 passes through the mounting frame 401 and extends into the interior of the guide tube 307. A plurality of fixing holes 403 are provided on the inner wall of the guide groove 306.

[0031] After the runway 2 is raised and lowered, the fixing rod 402 is pushed so that it can move out of the guide tube 307 and directly into the corresponding fixing hole 403. At this time, the fixing rod 402 can fix the runway 2 through the fixing hole 403. This setting ensures that the runway 2 will not suddenly drop after the separable drive assembly 5 separates from the screw 302.

[0032] In one embodiment, for the mounting frame 401, a support rod 404 is fixedly connected to the top of the mounting frame 401, an L-shaped push plate 405 is movably connected to the outer surface of the support rod 404, an inclined push groove 406 is provided on one side of the L-shaped push plate 405, a push rod 407 is movably connected inside the inclined push groove 406, the push rod 407 is fixedly connected to the fixed rod 402, a spring 408 is fixedly connected between the top of the L-shaped push plate 405 and the top of the inner wall of the mounting frame 401, and a connecting plate 409 is fixedly connected to the bottom of the support rod 404.

[0033] By pulling the L-shaped push plate 405 downwards, the L-shaped push plate 405 can pull the spring 408. At this time, the L-shaped push plate 405 can squeeze and push the push rod 407 through the inclined push groove 406. The moving push rod 407 can move the fixed rod 402, so that the fixed rod 402 can move into the fixed hole 403 through the guide tube 307. In the above configuration, the spring 408 can pull the L-shaped push plate 405 upwards, so that the L-shaped push plate 405 will not move downwards arbitrarily without the action of a large external force, thereby avoiding the fixed rod 402 from suddenly moving out of the guide tube 307 when adjusting the inclination of the runway 2.

[0034] In one embodiment, the detachable drive assembly 5 includes a hydraulic cylinder 501, which is fixedly installed on the bottom of the inner wall of the support frame 1. The output end of the hydraulic cylinder 501 is fixedly connected to a storage frame 502. A motor 503 is fixedly connected inside the storage frame 502. A sleeve 504 is fixedly connected to the output end of the motor 503. One end of the sleeve 504 extends to the outside of the storage frame 502. A connecting rod 505 is sleeved inside the sleeve 504. The connecting rod 505 is fixedly connected to a screw 302. One end of the limiting rod 305 passes through the fixing plate 301 and is movably connected to the storage frame 502.

[0035] By driving the motor 503, the sleeve 504 rotates on the storage frame 502. The rotating sleeve 504 drives the screw 302 to rotate through the sleeve rod 505 fitted inside it. After the inclination of the track 2 is adjusted, the hydraulic cylinder 501 is driven. At this time, the hydraulic cylinder 501 can drive the storage frame 502 to move backward. The moving storage frame 502 drives the motor 503 and the sleeve 504 to move backward synchronously, so that the sleeve rod 505 can move out from inside the sleeve 504. This setting prevents the vibration force transmitted from the track 2 from being transmitted to the motor 503 through the rotating plate 304 and the screw 302.

[0036] In one embodiment, the traction assembly 6 includes a storage cylinder 601, which is fixedly installed on the top of the fixing plate 301. A rotating shaft 602 is rotatably connected inside the storage cylinder 601. One end of the rotating shaft 602 passes through the storage cylinder 601 and is fixedly connected to a winding reel 603. A traction rope 604 is provided on the outside of the winding reel 603. A wire hole 605 is opened on the top of the connecting plate 409. The traction rope 604 is fixedly connected to the bottom of the L-shaped push plate 405 through the wire hole 605. A spiral spring 606 is fixedly connected between the rotating shaft 602 and the inner wall of the storage cylinder 601.

[0037] When the rotating plate 304 rotates and lifts the runway 2, the L-shaped push plate 405 continuously pulls the traction rope 604. At this time, the take-up reel 603 rotates under the pull of the traction rope 604, continuously releasing the traction rope 604 wrapped around its outside. The rotating take-up reel 603 drives the rotating shaft 602 to rotate continuously, thereby continuously tightening the spiral spring 606 inside the storage cylinder 601. The spiral spring 606 ensures that the traction rope 604 between the take-up reel 603 and the L-shaped push plate 405 is always in a taut state, thus preventing the traction rope 604 from getting tangled. At the same time, the overall elasticity of the spiral spring 606 is smaller than that of the spring 408, so that the taut traction rope 604 under the pull of the spiral spring 606 cannot pull the L-shaped push plate 405 downward.

[0038] In one embodiment, for the aforementioned rotating shaft 602, the other end of the rotating shaft 602 passes through the storage tube 601 and is fixedly connected to a gear 607, and a gear frame 608 is fixedly installed on the outside of the storage frame 502, with the gear frame 608 corresponding vertically to the gear 607.

[0039] When the storage frame 502 moves backward, the gear 608 on the storage frame 502 meshes with the gear 607. As the gear 608 moves continuously, the gear 607 drives the take-up reel 603 to rotate via the shaft 602, thereby causing the take-up reel 603 to wind up the traction rope 604. At this time, the L-shaped push plate 405 moves downward continuously under the pull of the traction rope 604, causing the fixing rod 402 to move into the fixing hole 403. When the sleeve 504 and the sleeve rod 505 are completely separated, the fixing rod 402 also moves completely into the fixing hole 403. In the above configuration, when the motor 503 drives the screw 302 through the sleeve 504 and the sleeve rod 505, the gear 608 and the gear 607 are not meshed. This configuration allows the traction rope 604 to move normally off the take-up reel 603 as the rotating plate 304 rotates continuously.

[0040] In one embodiment, for the storage frame 502, a plurality of bent sound-absorbing panels 7 are fixedly connected to the opening of the storage frame 502.

[0041] The storage frame 502 is made of sound-absorbing material, which absorbs the noise generated when the motor 503 is working. The bent sound-absorbing plate 7 at the opening of the storage frame 502 ensures the heat dissipation of the storage frame 502, and at the same time, residual noise cannot be transmitted through the bent sound-absorbing plate 7.

[0042] Through the above technical solution, 1. By moving the separable drive component 5 backward, the separable drive component 5 is separated from the lifting component 3. During this process, the traction component 6, driven by the separable drive component 5, can pull the elastic fixing component 4 through the traction end, thus fixing the front end of the track 2. This setting ensures that when the user runs on the track 2, the vibration force generated by the track 2 cannot be transmitted to the separable drive component 5, thereby avoiding damage to the separable drive component 5 due to vibration and improving its service life; 2. When the hydraulic cylinder 501 drives the storage frame 502 to move backward, the moving storage frame 502 can move out of the sleeve 504 from the outside of the sleeve 504, and the gear 60 Driven by the storage frame 502, the gear 607 meshes with the storage frame 502. As the storage frame 502 moves continuously, the gear 607 drives the winding reel 603 to rotate through the shaft 602, causing the winding reel 603 to wind up the traction rope 604. At this time, the L-shaped push plate 405 moves downward continuously under the pull of the traction rope 604. The moving L-shaped push plate 405 can push the fixing rod 402 into the fixing hole 403 through the inclined push groove 406 and the push rod 407. The above configuration can complete the separation and fixing operations simultaneously by moving the storage frame 502. At the same time, when the motor 503 and the sleeve 504 no longer limit the rotating plate 304 through the sleeve 504 and the screw 302, the track 2 will not suddenly drop under the fixing of the fixing rod 402 and the fixing hole 403.
