Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, and more specifically, to a multi-leg independent shock absorption structure for home treadmills. Background Technology

[0002] Treadmills are a common piece of fitness equipment in homes and gyms, and they are also one of the simplest types of home fitness equipment today. Treadmills allow you to run indoors without leaving your home, and running enthusiasts can exercise anytime, anywhere, regardless of the weather.

[0003] Traditional home treadmills are mostly placed stably on the ground. Since most treadmills in the current technology are supported by a fixed structure, most of the running impact is borne by the fixed support feet when exercising on the treadmill. As a result, the support feet cannot buffer the impact in time or control the range of buffering, and thus become damaged. At the same time, the current technology is also difficult to effectively buffer and adjust when facing the impact from the side of the treadmill, which leads to damage to the side of the treadmill.

[0004] To address the aforementioned technical shortcomings, a solution is provided. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a multi-leg independent shock absorption structure for home treadmills. This structure incorporates a pressure-absorbing mechanism and a clamping mechanism, along with multiple spring-loaded rollers positioned at the bottom support feet of the treadmill. Impact forces on the treadmill are absorbed and buffered by the springs and rollers. The buffering range is controlled by adjusting the movement of the rollers, preventing severe treadmill shaking. Furthermore, a side-support mechanism is incorporated to counteract excessive pressure on one side of the treadmill during use, causing it to sag. This reverse compression cushions the side with excessive pressure, preventing lateral damage to the treadmill and thus addressing the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-leg independent shock absorption structure for a home treadmill, comprising a treadmill shell, a handrail fixedly installed on the top of the treadmill shell, a running belt provided on the top of the treadmill shell, and a pressure-relieving mechanism and a clamping mechanism provided on the bottom of the treadmill shell;

[0007] The pressure-relieving mechanism includes multiple base plates fixedly installed at the bottom of the treadmill housing. A sleeve is fixedly installed at the bottom of the multiple base plates. A top rod is slidably installed on the inner wall of the multiple sleeves. A support spring is fixedly installed at the top of the top rod. The support spring is fixedly installed on the inner wall of the sleeve. The top rod is vertically downward. A bottom suction cup is fixedly installed at the bottom of the top rod. The bottom suction cup is horizontally positioned.

[0008] In a preferred embodiment, shafts are fixedly installed on both sides of the plurality of base plates, and sliding plates are rotatably installed on both sides of the two shafts. The plurality of sliding plates are arranged in pairs corresponding to each other, and rollers are rotatably installed on the bottom of the two sliding plates. The bottom of the rollers and the bottom of the bottom suction cup are on the same horizontal line.

[0009] In a preferred embodiment, the two slide plates are arranged symmetrically to each other, and a limit spring is fixedly installed on one side of both slide plates, the limit spring being arranged in a horizontal state.

[0010] In a preferred embodiment, the clamping mechanism includes a double-threaded rod disposed on the top of a plurality of base plates. The plurality of double-threaded rods are rotatably mounted on the bottom of the base plates. The plurality of double-threaded rods are arranged in a horizontal state. Clamping plates are threadedly connected to both sides of the plurality of double-threaded rods. Two clamping plates are arranged symmetrically to each other. The outer walls of the two clamping plates are provided with sliding grooves, which are formed at the bottom of the treadmill housing.

[0011] In a preferred embodiment, rubber strips are fixedly installed at the bottom of the two clamping plates, and the two rubber strips are arranged perpendicular to each other with the sliding plate. One side of the double threaded rod extends out of the outer wall of the treadmill housing, and a rotary wheel is fixedly installed on one side of the double threaded rod.

[0012] In a preferred embodiment, the bottom sides of the treadmill housing are provided with side top mechanisms. The side top mechanisms include limiting plates fixedly installed on the bottom sides of the treadmill housing. The two limiting plates are symmetrically arranged. Side push plates are rotatably installed on the bottom of the two limiting plates. The two side push plates are inclined downwards. A top limit support plate is provided on one side of the two side push plates. The top limit support plate is fixedly installed on the bottom of the limiting plates. Top support wheels are rotatably installed on the bottom of the two side push plates.

[0013] In a preferred embodiment, a fixing plate is fixedly installed on the top of the two side push plates, and a first magnet strip is hinged to the top of the two fixing plates. A limiting sleeve is fitted on the outer wall of the first magnet strip. The limiting sleeve is fixedly installed on the bottom of the treadmill housing. The limiting sleeve is open at the bottom. A second magnet strip is fixedly installed on the inner wall of the limiting sleeve. The bottom of the second magnet strip and the top of the first magnet strip are arranged opposite to each other.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention utilizes a pressure-reducing mechanism and a clamping mechanism. A rotating wheel drives a double-threaded rod, causing the clamping plates on both sides to move the rubber pressure strip closer to the sliding plates on both sides, thus controlling the offset position of the sliding plates. Multiple bottom suction cups on the bottom of the treadmill casing contact the ground and stabilize their position. The bottom suction cups are then subjected to reverse force, pressing against the top rod and support spring. The top rod, supported by the support spring, remains stable at the bottom of the sleeve. At this time, multiple rollers simultaneously contact the ground, generating impact force on the treadmill casing. The treadmill casing then presses down on the sliding plates on both sides of the shaft, causing the sliding plates on both sides to simultaneously drive the rollers to move to both sides and deflect. When the sliding plates on both sides move away from each other, they pull the limiting spring. Simultaneously, the bottom suction cups press against the top rod and support spring, causing the limiting spring and support spring to elastically deform and absorb the impact force. After the impact, they return to their original shape for further cushioning.

[0016] 2. Simultaneously, by setting up a side-top mechanism, when the impact force on the side of the treadmill casing is too large, the top support roller on one side of the treadmill casing gradually contacts the ground and rolls outward through the inclined structure of the side push plate. The side push plate deflects upward at the bottom of the limiting plate, and then the deflection of the side push plate drives the fixing plate and the first magnet strip to gradually approach the second magnet strip within the limiting sleeve box. Then, the like pole repulsion force between the first magnet strip and the second magnet strip reverses and squeezes the first magnet strip, that is, reverses and buffers the compression of the top support roller driven by the side push plate, thereby forming a supporting force on the side of the treadmill casing, preventing the treadmill from being damaged due to the inability to buffer and adjust its lateral position.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Since most existing treadmills use a fixed structure for support, during exercise, most of the impact force is borne by the fixed support feet. This results in the support feet being unable to effectively absorb the impact or control the range of impact, leading to damage. To solve this problem, the following technical solution is proposed:

[0027] Refer to the instruction manual appendix Figures 1-7 A multi-leg independent shock absorption structure for home treadmills, such as Figure 1 and Figure 2 As shown, the treadmill includes a treadmill housing 1, a handrail 2 fixedly installed on the top of the treadmill housing 1, a running belt 3 provided on the top of the treadmill housing 1, and a pressure-relieving mechanism 4 and a clamping mechanism 5 provided on the bottom of the treadmill housing 1.

[0028] like Figure 3 and Figure 4 As shown, the pressure-relieving mechanism 4 includes multiple base plates 41 fixedly installed at the bottom of the treadmill housing 1. A sleeve 42 is fixedly installed at the bottom of the multiple base plates 41. A top rod 43 is slidably installed on the inner wall of the multiple sleeves 42. A support spring 44 is fixedly installed at the top of the top rod 43. The support spring 44 is fixedly installed on the inner wall of the sleeve 42. The top rod 43 is set vertically downward. A bottom suction cup 45 is fixedly installed at the bottom of the top rod 43. The bottom suction cup 45 is set horizontally. The multiple bottom suction cups 45 at the bottom of the treadmill housing 1 contact the ground and stabilize their position. Then, the bottom suction cup 45 is subjected to force to press the top rod 43 and the support spring 44 in the opposite direction. As a result, the top rod 43 moves upward and retracts at the bottom of the sleeve 42.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a shaft 46 is fixedly installed on both sides of multiple base plates 41, and a sliding plate 47 is rotatably installed on both sides of the two shafts 46. The multiple sliding plates 47 are arranged in pairs corresponding to each other. Rollers 48 are rotatably installed on the bottom of the two sliding plates 47. The bottom of the rollers 48 is on the same horizontal line as the bottom of the bottom suction cup 45. When the multiple rollers 48 are subjected to downward pressure, the multiple rollers 48 drive the sliding plates 47 to move to both sides. That is, the sliding plates 47 on both sides deflect on both sides of the base plate 41 through the shafts 46.

[0030] like Figure 3 and Figure 4 As shown, the two sliding plates 47 are arranged symmetrically to each other. A limit spring 49 is fixedly installed on one side of both sliding plates 47. The limit spring 49 is set in a horizontal state. When the two sliding plates 47 move away from each other, the limit spring 49 is pulled, and the limit spring 49 undergoes elastic deformation to absorb the impact force. After the impact, it returns to its original state to facilitate buffering again.

[0031] like Figure 3 and Figure 5 As shown, the clamping mechanism 5 includes a double-threaded rod 51 disposed on the top of multiple base plates 41. The multiple double-threaded rods 51 are rotatably mounted on the bottom of the base plates 41. The multiple double-threaded rods 51 are arranged in a horizontal state. Clamping plates 52 are threadedly connected to both sides of the multiple double-threaded rods 51. The two clamping plates 52 are arranged symmetrically to each other. The outer wall of the two clamping plates 52 is provided with a sliding groove 53. The sliding groove 53 is opened at the bottom of the treadmill housing 1. By rotating the double-threaded rods 51, the clamping plates 52 on both sides are driven to move closer to each other on the inner wall of the sliding groove 53.

[0032] like Figure 3 and Figure 5 As shown, rubber pressure strips 54 are fixedly installed at the bottom of the two clamping plates 52. The two rubber pressure strips 54 are set perpendicular to each other with the sliding plate 47. The clamping plates 52 on both sides drive the rubber pressure strips 54 to move closer to the sliding plate 47 on both sides, thereby controlling the offset position of the sliding plate 47. This facilitates the control of the sliding plate 47 during buffering movement. That is, the strength of the buffer is controlled by controlling the offset angle of the sliding plate 47, and the sliding plate 47 is prevented from being too loose, which would cause the bottom of the treadmill housing 1 to shake. One side of the double threaded rod 51 extends out of the outer wall of the treadmill housing 1. A dial wheel 55 is fixedly installed on one side of the double threaded rod 51, so that the double threaded rod 51 can be rotated by rotating the dial wheel 55.

[0033] In specific implementation, the double threaded rod 51 is first rotated by rotating the dial wheel 55. The rotation of the double threaded rod 51 causes the clamping plates 52 on both sides to move closer to each other on the inner wall of the slide groove 53. Then, the clamping plates 52 on both sides cause the rubber pressure strip 54 to move closer to the position of the slide plate 47 on both sides, thereby controlling the offset position of the slide plate 47.

[0034] Then, the multiple bottom suction cups 45 at the bottom of the treadmill housing 1 contact the ground and stabilize their position. The bottom suction cups 45 are then subjected to reverse force to press the top rod 43 and the support spring 44. The top rod 43 is then supported by the support spring 44 and remains stable at the bottom of the sleeve 42. At this time, the multiple rollers 48 simultaneously contact the ground and generate impact force on the treadmill housing 1. The treadmill housing 1 then presses the multiple bottom support plates 41 downwards, that is, the multiple bottom support plates 41 press the sliding plates 47 on both sides of the shaft rod 46. As a result, the sliding plates 47 on both sides simultaneously drive the rollers 48 to move to both sides and deflect. When the sliding plates 47 on both sides move away from each other, they pull the limiting spring 49. At the same time, the bottom suction cups 45 press the top rod 43 and the support spring 44. As a result, the limiting spring 49 and the support spring 44 undergo elastic deformation to absorb the impact force and then recover after the impact to facilitate further cushioning.

[0035] Example 2: Furthermore, existing technologies struggle to effectively cushion and adjust for lateral impacts on treadmills, leading to lateral damage. To address this issue, the following technical solution is proposed:

[0036] like Figure 6 and Figure 7 As shown, side top mechanisms 6 are provided on the bottom sides of both sides of the treadmill housing 1. The side top mechanisms 6 include limiting plates 61 fixedly installed on the bottom sides of both sides of the treadmill housing 1. The two limiting plates 61 are symmetrically arranged. Side push plates 62 are rotatably installed on the bottom of the two limiting plates 61. The two side push plates 62 are inclined downwards. A top limiting plate 63 is provided on one side of the two side push plates 62. The angle of the side push plates 62 is limited by the top limiting plate 63, so that the top support roller 64 driven by the side push plate 62 is located on the roller 4. The top of 8, so that the top support roller 64 driven by the side push plate 62 is only used for support when the impact force on the side of the treadmill shell 1 is too large. The top limit plate 63 is fixedly installed at the bottom of the limit plate 61. The bottom of the two side push plates 62 is rotatably installed with the top support roller 64. When the impact force on the side of the treadmill shell 1 is too large, the top support roller 64 on one side of the treadmill shell 1 contacts the ground and rolls outward through the inclined structure of the side push plate 62, and the side push plate 62 deflects upward at the bottom of the limit plate 61.

[0037] like Figure 6 and Figure 7As shown, a fixing plate 65 is fixedly installed on the top of the two side push plates 62. A first magnetic strip 66 is hinged to the top of the two fixing plates 65. A limiting box 67 is fitted on the outer wall of the first magnetic strip 66. The limiting box 67 is fixedly installed at the bottom of the treadmill housing 1. The limiting box 67 is open at the bottom. A second magnetic strip 68 is fixedly installed on the inner wall of the limiting box 67. The bottom of the second magnetic strip 68 and the top of the first magnetic strip 66 are arranged opposite to each other. Then, the side push plate 62 deflects, causing the fixing plate 65 and the first magnetic strip 66 to move upward synchronously. Then, the first magnetic strip 66 gradually approaches the second magnetic strip 68 in the limiting box 67. Thus, the like repulsive force between the first magnetic strip 66 and the second magnetic strip 68 squeezes the first magnetic strip 66 in the opposite direction, that is, it buffers and squeezes the top support roller 64 driven by the side push plate 62 in the opposite direction, thereby forming a supporting force on the side of the treadmill housing 1, and preventing the treadmill from being damaged due to the inability to buffer and adjust the lateral position.

[0038] In practical implementation, when the impact force on the side of the treadmill casing 1 is too large, the top support roller 64 on one side of the treadmill casing 1 gradually contacts the ground and rolls outward through the inclined structure of the side push plate 62. The side push plate 62 deflects upward at the bottom of the limiting plate 61. Then, the deflection of the side push plate 62 drives the fixing plate 65 and the first magnetic strip 66 to move upward synchronously. The first magnetic strip 66 gradually approaches the second magnetic strip 68 in the limiting sleeve box 67. Then, the like repulsion force between the first magnetic strip 66 and the second magnetic strip 68 squeezes the first magnetic strip 66 in the opposite direction, that is, it buffers and squeezes the top support roller 64 driven by the side push plate 62 in the opposite direction, thereby forming a supporting force on the side of the treadmill casing 1, and preventing the treadmill from being damaged due to the inability to buffer and adjust the lateral position.
