Description

Technical Field

[0001] This utility model belongs to the field of treadmill technology, and in particular relates to a treadmill running platform structure with adjustable cushioning characteristics. Background Technology

[0002] To improve runner comfort and reduce operating noise, treadmill running platforms now commonly incorporate cushioning designs. For example, Chinese Patent Application No. 202421655698.6 discloses a treadmill running platform structure that achieves cushioning through soft, elastic strips installed inside the platform. This design effectively absorbs impact the moment a runner's foot strikes the running board, avoiding rigid contact and thus protecting the runner's knees and ankles, reducing sports injuries and discomfort.

[0003] However, the soft, elastic strips relied upon by the above solutions do not offer adjustable stiffness. A single cushioning stiffness setting is insufficient to accommodate the diverse needs of different users (such as weight, exercise habits, and joint pressure tolerance) as well as varying running intensities (such as brisk walking, jogging, and sprinting). This limits the personalized cushioning experience and fails to provide optimal joint protection and comfort for all users. Utility Model Content

[0004] To address the shortcomings of existing technologies, a treadmill running platform structure with adjustable cushioning hardness is provided.

[0005] This utility model is achieved using the following technical solution: a treadmill running platform structure with adjustable cushioning hardness, comprising a running platform frame, a running board, and a running belt, wherein the running board comprises:

[0006] A modular soft elastic strip is set on a running table and extends along the length of the running table. It is composed of multiple independent and replaceable soft elastic conditions spliced ​​together, each of which has its own independently selectable Shore hardness.

[0007] Multiple rigid support bars extend along the width direction of the running platform and are arranged along the length direction of the running platform. The rigid support bars are laid on the combined soft elastic strip plate.

[0008] The running belt is arranged around the length of the running platform and laid on the running board.

[0009] The soft elastic panels in this solution are modular, consisting of multiple independent, replaceable soft elastic elements arranged side-by-side. Therefore, different users can select and combine soft elastic elements with varying Shore hardness to create panels with different cushioning hardnesses. This adapts to the diverse needs of different users and varying running intensities, providing optimal joint protection and comfort.

[0010] Preferably, a mutually cooperating connection structure is provided between two adjacent soft elastic conditions, the connection structure including a positioning protrusion extending along the length direction of the running platform and a positioning groove for the positioning protrusion to be embedded in.

[0011] There is a matching connection structure between two adjacent flexible conditions, which facilitates the positioning of the two adjacent flexible conditions and makes the stability of the entire combined flexible strip better.

[0012] Preferably, the positioning groove has a wide section and a narrow section from the inside out, and the positioning protrusion has a large diameter section and a small diameter section that are adapted to the positioning groove.

[0013] The above settings make it difficult for two adjacent flexible elastic conditions to separate after connection, thus ensuring the stability of the entire combined flexible elastic strip.

[0014] Preferably, the positioning groove penetrates the upper and / or lower end face of the soft elastic condition, so that the positioning protrusion is embedded in the positioning groove in the vertical direction.

[0015] This setup ensures that the separation between two adjacent flexible conditions must also be a vertical separation trajectory. Since the rigid support strip is laid and supported on the combined flexible strip, it can compress the combined flexible strip, thereby preventing the separation between two adjacent flexible conditions.

[0016] Preferably, the combined soft elastic strip is fitted with a noise-reducing sleeve for noise reduction.

[0017] Noise reduction can be achieved by using a noise-reducing sleeve, which can be made of non-woven fabric. The noise-reducing sleeve will not affect the overall buffer strength of the combined soft elastic strip.

[0018] Preferably, the upper end of the end edge of the rigid support bar is provided with a strip-shaped connecting plate extending along the length direction of the treadmill frame. The strip-shaped connecting plate is equipped with locking members that correspond one-to-one with the rigid support bars. The locking members fix all the rigid support bars to the strip-shaped connecting plate, and the strip-shaped connecting plate is fixedly connected to the treadmill frame.

[0019] By setting up strip connecting plates, all rigid support strips can be fixed together, preventing the rigid support strips from shifting in space.

[0020] Preferably, the running board also includes a wear-resistant plate, which is fixed and laid on the rigid support strip, and the running belt is in direct contact with the wear-resistant plate.

[0021] Preferably, the combined soft elastic strip is provided at least in the central stepping area of ​​the treadmill frame.

[0022] The central stepping area of ​​the running platform is where users tend to step, so installing a combination of soft, elastic strips here can save costs and also provide cushioning.

[0023] Preferably, the top surface of the flexible elastic condition is provided with an upwardly extending limiting part, which extends along the length direction of the running platform. An L-shaped placement groove is formed between the limiting part and the top surface of the flexible elastic condition, and the end of the rigid support bar is placed in the placement groove.

[0024] The placement groove can better limit the rigid support bar.

[0025] Preferably, the longitudinal cross-sectional shape of the soft elastic condition is rectangular.

[0026] The longitudinal cross-sectional shape of the soft elastic condition is rectangular, so that after splicing the combined soft elastic strips, the combined soft elastic strips form a complete cuboid structure.

[0027] Compared with existing technologies, the beneficial effects of this invention are as follows: The soft elastic strip in this solution is modular, consisting of multiple independent, replaceable soft elastic elements arranged side by side. Therefore, different Shore hardness soft elastic elements can be selected and spliced ​​together to cater to different user groups, resulting in a modular soft elastic strip with varying cushioning hardness. This adapts to the diverse needs of different users and varying running intensities, providing users with optimal joint protection and comfort. Attached Figure Description

[0038] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1 and Figure 2 As shown, this embodiment discloses a treadmill running platform structure with adjustable cushioning characteristics, including a running platform frame 1, a running board, and a running belt 2. The running platform frame 1 forms the frame of the entire treadmill running platform. A motor 11 and two drive rollers 3 located at both ends of the running platform frame 1 along its length are installed on the running platform frame 1. The motor 11 can drive the drive rollers 3 to rotate, and the running belt 2 wraps around the drive rollers 3 along the length of the running platform frame 1. When the motor 11 rotates, the running belt 2 can rotate.

[0040] A running board is provided between the two drive rollers 3 to support the running belt 2. The running platform 1 includes a longitudinal beam 12 extending along its length (longitudinal direction) and a transverse beam 13 extending along its width (transverse direction), with the running board provided between the longitudinal beam 12 and the transverse beam 13. The running board includes a composite soft elastic strip, which is set on the two longitudinal beams 12 and extends in the longitudinal direction. It is composed of multiple independent, replaceable soft elastic conditions 7 spliced ​​together, each soft elastic condition 7 having its own independently selectable Shore hardness. Soft elastic conditions 7 with different or the same Shore hardness can be selected and spliced ​​together to form running boards with different cushioning strengths.

[0041] like Figures 4 to 7As shown, the flexible elastic condition 7 is made of a composite polymer material. A mutually engaging connection structure is provided between two adjacent flexible elastic conditions 7. The connection structure includes a positioning protrusion 72 extending longitudinally and a positioning groove 71 into which the positioning protrusion 72 is inserted. The positioning groove 71 penetrates the wall of the flexible elastic condition 7 vertically, allowing the positioning protrusion 72 to be inserted vertically into the positioning groove 71. The positioning groove 71 has a wide section 711 and a narrow section 712 sequentially from the inside out. The cross-section of the wide section 711 is circular, and the cross-section of the narrow section 712 is trapezoidal. The width of the narrow section 712 is smaller than the width of the wide section 711. The positioning protrusion 72 has a large-diameter section 721 and a small-diameter section 722 that fit the wide section 711 and the narrow section 712 of the positioning groove 71. This ensures that the positioning protrusion 72 cannot be separated horizontally after being inserted into the positioning groove 71.

[0042] The top surface of the soft elastic condition 7 is provided with an upwardly extending limiting part 73. The limiting part 73 extends along the length direction of the running platform 1, and an L-shaped placement groove is formed between the limiting part 73 and the top surface of the soft elastic condition 7.

[0043] like Figures 1 to 5 As shown, longitudinal limiting blocks 81 are provided at both ends of the longitudinal beam 12, and several transverse limiting blocks 82 are provided along its length. The longitudinal limiting blocks 81 and transverse limiting blocks 82 limit the combined soft elastic strip in the longitudinal and transverse directions.

[0044] Multiple rigid support strips 6 are laid on the combined flexible strip plate. The rigid support strips 6 extend in the transverse direction, and their two ends are supported in the L-shaped placement grooves of the combined flexible strip plate. At both ends of the rigid support strips 6, there are also strip connecting plates 5. The strip connecting plates 5 are fixed to the longitudinal beams 12 of the running platform frame, and the strip connecting plates 5 are equipped with locking parts 51 that correspond one-to-one with the rigid support strips 6. The locking parts 51 can be bolts and nuts to realize the connection and fixation between the strip connecting plates 5 and the rigid support strips 6, or they can be rivets to realize the connection and fixation between the strip connecting plates 5 and the rigid support strips 6, etc.

[0045] A wear-resistant plate 4 is provided on the plane formed by the rigid support bar 6. The wear-resistant plate 4 is fixed and laid on the rigid support bar 6. The running belt 2 is arranged around the running platform 1 along the length direction and laid on the wear-resistant plate 4.

[0046] like Figure 6 As shown, the combined soft elastic strip outer cover is equipped with a noise reduction sleeve 9 for noise reduction, which is made of existing non-woven fabric material.

[0047] In some other embodiments, the combined flexible strips may be placed only in the central stepping area of ​​the treadmill frame, i.e., the central area of ​​the longitudinal beam 12. Any other existing flexible strips may be used to fill the non-central areas of the longitudinal beam 12.

[0048] like Figure 8 and Figure 9 As shown, in some other embodiments, the soft elastic condition 7 may not have a limiting part 73, and its longitudinal cross-sectional shape is rectangular, so that after the soft elastic condition 7 is spliced ​​into a combined soft elastic strip, the combined soft elastic strip is a complete cuboid structure.
