[0002] Treadmills are a popular choice among modern fitness equipment due to their ability to provide indoor aerobic exercise. However, traditional treadmills, with their continuous impact from the running belt, often put significant pressure on users' joints, potentially leading to injuries with prolonged use. To alleviate this issue, some treadmills with cushioning functions have emerged on the market, but most of these products use a fixed cushioning structure, lacking flexibility to be personalized based on factors such as user weight and running habits, thus limiting their cushioning effectiveness. Therefore, designing a treadmill cushioning adjustment structure that can flexibly adjust the cushioning force to adapt to different user needs is particularly important. Utility Model Content

[0003] The main purpose of this utility model is to provide a cushioning adjustment structure and its cushioning components for a treadmill, which solves the problems existing in the prior art and can adjust the cushioning force according to different usage needs.

[0004] To achieve the above objectives, one of the solutions of this utility model is: A buffer includes a support body made of elastic material and a support rod disposed within the support body; with the direction in which the support body performs its supporting function as a reference, the left-right direction is defined as length, the front-back direction as width, and the up-down direction as height; the length and height of the support body are equal, and a through groove is provided therein, the through groove penetrating the front and back surfaces of the support body; the two ends of the support rod are integrally connected to the two ends of the inner wall of the through groove, respectively.

[0005] The support body has diagonal slopes on all four sides (top, bottom, left, and right), and the edges of the slopes are rounded to transition with the adjacent surfaces.

[0006] The through groove has a racetrack-shaped cross section, which includes a pair of parallel planes and a pair of arc surfaces connected between adjacent ends of the planes; the two ends of the support rod are integrally connected to the two arc surfaces respectively.

[0007] Preferably, the middle section of the support rod is provided with a reduced diameter section, and the diameter of the support rod gradually decreases from both ends toward the reduced diameter section.

[0008] The second solution of this utility model is: A treadmill cushioning adjustment structure includes the aforementioned cushioning component, a main frame assembly, and a running board; the inner wall of the side tube of the main frame assembly is provided with a plurality of fixing seats for mounting the cushioning component; the cushioning component is embedded in the fixing seats and the support rod is arranged in a vertical or horizontal direction; the running board is disposed in the main frame assembly, and the lower surface of its two side edges is supported by the upper surfaces of a plurality of cushioning components respectively.

[0009] The fixing seat is provided with a fixing groove that matches the buffer. The top of the fixing groove and the side adjacent to the inner side of the main frame assembly are open, and the bottom surface of the fixing groove extends upward to form a baffle.

[0010] The treadmill's cushioning adjustment structure also includes a running belt, which is tensioned and fitted onto the pivot of the main frame assembly and wrapped around the surface of the running belt.

Detailed Implementation

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0021] refer to Figure 1 , Figure 2 As shown, this is the first embodiment of the present invention, which discloses a buffer 1, including a support body 11 made of elastic material and a support rod 12 disposed in the support body 11. Taking the direction in which the support body 11 performs its support function as a reference, the left and right direction is defined as the length, the front and back direction as the width (thickness), and the up and down direction as the height. The length and height of the support body 11 are equal, and a through groove 111 is provided inside it, which penetrates the front and back surfaces of the support body 11. Both ends of the support rod 12 are integrally connected to both ends of the inner wall of the through groove 111.

[0022] The following shows the structural details of the first embodiment: The aforementioned elastic materials can be rubber, PVC (polyvinyl chloride), etc.

[0023] The aforementioned support body 11 has diagonal bevels 112 on each of its four sides (top, bottom, left, and right), with rounded edges between the bevels 112 and adjacent surfaces. By designing the bevels 112, the buffer component 1 is easier to insert and remove during actual assembly and disassembly.

[0024] The aforementioned through groove 111 has a racetrack-shaped cross-section, comprising a pair of parallel planes 1111 and a pair of arc surfaces 1112 respectively connected between adjacent ends of the planes 1111; both ends of the support rod 112 are integrally connected to the two arc surfaces 1112 respectively. This enriches the detailed design of the buffer 1, enabling it to meet the function of adjustable buffering force in actual production.

[0025] Furthermore, the middle section of the support rod 112 is provided with a reduced diameter section 1121, and the diameter of the support rod 112 gradually decreases from both ends toward the reduced diameter section 1121. This increases the cushioning performance of the buffer member 1.

[0026] Specifically, in the first embodiment, the length and height of the support body 11 are set to 50~100mm, the width of the racetrack-shaped through groove 111 is set to 25~50mm, the length is set to 35~70mm, and the maximum diameter (end diameter) of the support rod 12 is set to 18~36mm and the minimum diameter (diameter of the reduced diameter portion 1121) is set to 10~20mm.

[0027] refer to Figure 3 , Figure 4 As shown, this is the second embodiment of the present invention, which discloses a cushioning adjustment structure for a treadmill, including the aforementioned cushioning component 1, as well as the main frame assembly 2 and the running board 3. The inner wall of the side tube 21 of the main frame assembly 2 is provided with several fixed seats 22 for installing the buffer component 1; the buffer component 1 is embedded in the fixed seat 22 and the support rod 12 is arranged in the up-down or left-right direction. The running board 3 is set inside the main frame assembly 2, and the lower surfaces of its two side edges are supported by the upper surfaces of several buffer components 1.

[0028] The following shows the structural details of the second embodiment: The aforementioned fixing seat 22 is provided with a fixing groove 221 that matches the buffer 1. The top of the fixing groove 221 and the side adjacent to the inner side of the main frame assembly 2 are open, and the bottom surface of the fixing groove 221 extends upward to form a baffle 222, which is used to prevent the buffer 1 from moving horizontally.

[0029] The second embodiment also includes a running belt 4, which is tensioned and fitted onto the pivot of the main frame assembly 2 and wrapped around the surface of the running belt 4. The two sides of the running board 3 protrude from the two sides of the running belt 4 respectively.

[0030] Furthermore, the aforementioned fixing seats 22 are arranged at equal intervals along the forward direction of the running belt 4.

[0031] The second embodiment also includes a base assembly 5 located below the front end of the main frame assembly 2, and a pair of rollers 6 located below the rear end of the main frame assembly 2; an electric telescopic rod 7 is provided between the base assembly 2 and the main frame assembly 2. Thus, the front end of the main frame assembly 2 can be raised and lowered via the electric telescopic rod 7 to adjust the pitch angle. Furthermore, the treadmill's motor and other electrical components are also housed within the base assembly 5.

[0032] Both ends of the inner wall of the side tube 21 of the main frame assembly 2 are provided with several brackets 8 for fixing the running board 3. This allows for relative fixation between the running board 3 and the main frame assembly 2, and the edges of the running board 3 are cushioned by the buffer 1 to avoid rigid contact. The brackets 8 and the running board 3 can be secured with bolts.

[0033] Through the above solution, this utility model designs a buffer 1, which can be installed in the main frame assembly 2 of the treadmill to support the running board 3, thereby enabling the running board 3 to have a buffering function to reduce the impact on the human joints; at the same time, the through groove 111 of the buffer 1 provides its deformation space, and the support rod 12 in the through groove 111 can provide different buffering forces when the placement direction of the buffer 1 is different (up and down or left and right). Therefore, users only need to rotate the direction of the buffer 1 or replace it with other specifications of buffers to adjust the buffering force of the running board 3 to meet different exercise needs.

[0034] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
