Description

Technical Field

[0001] The present invention relates to the technical field of electric treadmills, and more specifically to a treadmill of an electric treadmill. Background Art

[0002] In the prior art, the running platform of a traditional treadmill is a flat running board set on the running platform. The running board itself has no shock absorption function, and the shock absorption is achieved by other additional accessories such as springs and cushions. The defect of this type of treadmill is that although the springs and cushions can have a certain buffering effect, the moment the user lands on the running board, he or she is stepping on a hard surface.

[0003] Another type is a treadmill platform with an arched running board, which includes a frame and a running board, and the two ends of the running board are fixedly connected to the frame by bolts; the running board is a flat plate, and N adjustment blocks are fixed on the left and right sides of the frame, and the running boards fixed at both ends are supported by the adjustment blocks to form an arc that bulges upward. A treadmill, which includes a frame and a running board, is characterized in that the two ends of the running board are fixedly connected to the frame by bolts; the running board is a flat plate, and adjustment blocks are respectively arranged on the left and right sides of the frame, and the adjustment blocks are integrally formed with the frame or are combined separately. Although the shock absorption of the running board of this type of treadmill is effective, the arched board is generally designed to release tension forward or backward. When releasing tension forward or backward, the user's knees are subjected to buffering and shock absorption in only one direction. However, a certain arched board that releases tension forward and backward at the same time has obvious rebound resonance, and the stability and experience are relatively poor. And the cost of the arched board is very high. Furthermore, if the bow plate does not have a device to eliminate resonance, the user will experience a feeling of one foot deep and one foot shallow when landing during running, just after the bow plate deforms downward and before it rebounds. Summary of the invention

[0004] The present invention provides a running platform of an electric treadmill.

[0005] The technical measures adopted in this scheme are: a running platform of an electric treadmill, which includes a frame and a running board, the frame includes a left frame, a right frame and a plurality of cross braces, the cross braces placed between the left frame and the right frame are fixedly connected with the left frame and the right frame to form an integral frame; a plurality of adjustment blocks of different heights are fixed on the frame so that the bottom surface of the running board is pressed against the adjustment blocks to form a hyperbolic surface, and the running board is fixed to the frame by a plurality of running board fixing belts.

[0006] The specific feature of the present solution is that a plurality of adjustment blocks are arranged on the cross brace of the frame, the adjustment blocks are made of elastically deformable materials, and a running board is arranged above the adjustment blocks.

[0007] The running board fixing belt is a flexible fixing belt. It wraps around the cross brace from bottom to top and is fixedly connected to the running board. One end of the running board fixing belt is fixed to the running board, and the other end is fixed to the running board after passing through the cross brace. The running board fixing belt fixes the running board to the cross brace of the treadmill through screws. The running board fixing belt is tightened by screws, and the adjustment blocks of different heights between the cross brace and the running board are used to deform the running board to form a hyperbolic treadmill.

[0008] The adjustment blocks include four corner adjustment blocks, front and rear adjustment blocks, left and right adjustment blocks and a central adjustment block. The four corner adjustment blocks are located on the front and rear cross braces corresponding to the four corners of the bottom surface of the running board, the front and rear adjustment blocks are located in the middle of the front and rear cross braces and correspond to the middle of the front and rear ends of the running board, the left and right adjustment blocks are located on the middle cross brace and correspond to the left and right sides of the middle bottom surface of the running board, and the central adjustment block is located on the middle cross brace and corresponds to the center of the bottom surface of the running board.

[0009] The height of the adjustment block is: the four corner adjustment blocks < the front and rear adjustment blocks < the left and right adjustment blocks < the central adjustment block, that is, the front and rear axis curved surface of the running board is larger than the left and right axis curved surface.

[0010] The running board is a flat board. The running board fixing belt tightens the running board to fix it. The running board is lifted up and deformed by the adjustment block, and deforms from a flat board to a hyperbolic panel. The reasonable range of the hyperbolic surface of the running board is that the arc height of the outermost side of the front and rear axes is between 12mm and 40mm, and the arc height of the outermost side of the left and right axes is between 8mm and 18mm. The arc height refers to the vertical distance from the lowest point to the highest point of the bottom of the running board. The ratio of the arc height of the outermost side of the front and rear axes of the running board to the running board is between 1.2% and 2.5%, and the ratio of the arc height of the outermost side of the left and right axes of the running board to the running board is between 1.5% and 2.8%.

[0011] The running deck is a hyperbolic panel, which is directly placed on the adjustment block and fixed by a running deck fixing belt.

[0012] The left frame, right frame and cross brace are rectangular tubes.

[0013] The chassis fixing seat is arranged at the front end of the frame, and the front roller and the rear roller are arranged in the frame.

[0014] The upper chassis cover and the lower chassis cover are fixed on the chassis fixing seat and the left frame and the right frame. The running belt wraps the running board and the running platform cross brace, and is tightened and fixed by the front roller and the rear roller.

[0015] The beneficial effect of this solution is that the treadmill is designed as a hyperbolic surface. The hyperbolic treadmill can release tension in four directions: forward, backward, left and right, or can be adjusted to release tension in a fan-shaped range forward or backward according to needs. Thereby, the impact force during running is released more evenly, thereby achieving an effective shock-absorbing effect. And during the rotation of the running belt, the force on the central axis is always greater than that on the left and right sides, which can prevent the running belt from running off the track and automatically align it. During the use of the hyperbolic treadmill, because the elastic deformation of the hyperbolic treadmill releases tension to the surrounding areas, the deformation amounts of the front and rear axes and the left and right axes are different, and the resonance will be offset each other. When the user lands, he is always on the highest surface of the hyperbolic surface, that is, the hyperbolic running board is subjected to the impact force of the landing, so that the running board releases tension to the surrounding areas, which has the effect of buffering and shock absorbing. The elastic deformation of the running board will not cause the user's feet to step on the concave deformation, and there will be no deep and shallow experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] like Figure 1 As shown, a running platform of an electric treadmill comprises a frame and a running board, wherein the frame comprises a left frame, a right frame and a plurality of cross braces, wherein the cross braces disposed between the left frame and the right frame are fixedly connected to the left frame and the right frame to form an integral frame; a plurality of adjustment blocks of different heights are fixed on the frame so that the bottom surface of the running board is pressed against the adjustment blocks to form a hyperbolic surface, and the running board is fixed to the frame by a plurality of running board fixing belts.

[0019] like Figure 4 and 5 As shown, a plurality of adjustment blocks are arranged on the cross brace of the frame, and the adjustment blocks are made of elastically deformable materials, such as rubber, soft plastic, etc., and the compression deformation of the adjustment blocks is 10% to 40% of the height of the adjustment blocks. A running board 10 is arranged above the adjustment blocks.

[0020] When the compression deformation of the adjustment block is smaller, the elasticity is worse. Under the premise of ensuring that the running board has sufficient elastic deformation, the arc height of the running board is required to be relatively high, that is, the height of the adjustment block is relatively high; on the contrary, when the compression deformation of the adjustment block is larger, the elasticity is stronger, and the arc height of the running board can be relatively low, that is, the height of the adjustment block is relatively low. That is, the compression deformation and height of the adjustment block determine the shape of the hyperbolic running board. In this way, the appropriate adjustment block can be selected according to the height requirements of the treadmill and the space requirements of the overall design.

[0021] The running board fixing belt 11 is a flexible fixing belt. The material of the running board fixing belt 11 is generally a nylon material with no elastic deformation, and can withstand a tensile force of not less than 1000N. One end of the running board fixing belt 11 is fixed on the running board 10, and the other end is fixed on the running board 10 after passing through the running platform cross brace 6 and applying a pre-tightening force. That is, the running board fixing belt 11 is wrapped around the running platform cross brace 6 from bottom to top and is fixedly connected to the running board 10 by screws. Through the pre-tightening force of the running board fixing belt 11 and the adjustment blocks of different heights between the cross brace 6 and the running board 10, the running board 10 is deformed to form a hyperbolic running board. The running board fixing belt 11 is distributed on the vertical planes on both sides of the running board 10.

[0022] During the use of the hyperbolic treadmill, because the elastic deformation of the hyperbolic treadmill releases tension in all directions, the deformation amounts of the front and rear axes and the left and right axes are different, which will offset the resonance between each other. When the user lands, he is always on the highest surface of the hyperbolic surface, that is, the hyperbolic running board is subjected to the impact force of the landing, which causes the running board to release tension in all directions, thus achieving the effect of buffering and shock absorption. The user's feet will not step on the concave deformed area due to the elastic deformation of the running board.

[0023] like Figure 3 and 5 As shown, the adjustment blocks include four corner adjustment blocks, front and rear adjustment blocks, left and right adjustment blocks and a central adjustment block. The four corner adjustment blocks 12 are located on the front and rear cross braces corresponding to the four corners of the bottom surface of the running board 10, the front and rear adjustment blocks 13 are located in the middle of the front and rear cross braces and correspond to the middle of the front and rear ends of the running board 10, the left and right adjustment blocks 14 are located on the middle cross brace and correspond to the left and right sides of the middle bottom surface of the running board 10, and the central adjustment block 15 is located on the middle cross brace and corresponds to the center of the bottom surface of the running board 10.

[0024] The heights of the adjustment blocks are as follows: the four corner adjustment blocks 12 < the front and rear adjustment blocks 13 < the left and right adjustment blocks 14 < the central adjustment block 15 , that is, the front and rear axis curved surface of the running board 10 is larger than the left and right axis curved surface.

[0025] The running board 10 is a flat plate. The running board fixing belt 11 tightens and fixes the running board 10 through a pre-tightening force. The running board 10 is lifted up and deformed by the adjusting block, and is deformed from a flat plate to a hyperbolic plate.

[0026] The running board 10 is a hyperbolic board. The running board 10 is directly placed on the adjustment block and fixed by a running board fixing belt 11 .

[0027] like Figure 4 As shown, the left frame 4, the right frame 5 and the running platform cross brace 6 are rectangular tubes.

[0028] The chassis fixing seat 7 is arranged at the front end of the treadmill frame, and the front roller 8 and the rear roller 9 are arranged in the treadmill frame.

[0029] like Figure 1 and 2 As shown, the upper chassis cover 2 and the lower chassis cover 3 are fixed on the chassis fixing seat 7 and the left frame 4 and the right frame 5, the treadmill 1 wraps the running board 10 and the treadmill cross brace 6, and is tightened and fixed by the front roller 8 and the rear roller 9.

[0030] like Figure 1 and 5 As shown, when the tension of the hyperbolic running board is released, since all the running board fixing belts 11 are flexibly fixed, the running board 10 can release the tension in four directions: forward, backward, left and right. When the user is running, the running board 10 is subjected to pressure when the foot lands, and the tension is released in all directions due to elastic deformation, and each adjustment block is compressed and deformed. When the foot is lifted, the adjustment block rebounds to restore the deformation of the running board. The elastic deformation degree of the entire running board is determined by the hardness of the adjustment block and the thickness of the running board, that is, the harder the adjustment block, the smaller the deformation, and the softer the adjustment block, the greater the deformation; the thicker the running board, the smaller the deformation, and the thinner the running board, the greater the deformation. And the adjustment blocks can be added or reduced according to the length of the running board, so that the hyperbolic surface of the running board is within a reasonable range of use.

[0031] If the running board fixing belt 11 at the front end of the running board 10 is changed from a flexible fixing mode to a locking fixing mode, then when the tension of the hyperboloid surface is released, the releasing direction is changed from the surrounding direction to a fan-shaped range to the left and right rear; if the running board fixing belt 11 at the rear end of the running board 10 is changed from a flexible fixing mode to a locking fixing mode, then when the tension of the hyperboloid surface is released, the releasing direction is changed from the surrounding direction to a fan-shaped range to the left and right front.

[0032] Since the running belt 1 is wrapped around the hyperbolic running board, the running belt 1 itself is not a hyperbolic surface, but is affected by the deformation of the running board 10. Since the front-rear axis curved surface of the running board 10 is larger than the left-right axis curved surface, the running belt 1 forms a curved surface with an upper end surface of the front-rear axis arch. That is, the running belt 1 is in close contact with the front-rear axis center of the running board 10, but is not completely in contact with the left and right parts of the front-rear axis of the running board 10. When the running belt is rotating, the force on the center axis is always greater than that on the left and right sides, which can prevent the running belt from deviating and automatically align.

[0033] The reasonable range of the hyperboloid of the running board 10 is that the arc height of the outermost side of the front and rear axes is between 12mm and 40mm, and the arc height of the outermost side of the left and right axes is between 8mm and 18mm. The arc height refers to the vertical distance from the lowest point to the highest point of the bottom of the running board. The ratio of the arc height of the outermost side of the front and rear axes of the running board to the running board is between 1.2% and 2.5%, and the ratio of the arc height of the outermost side of the left and right axes of the running board to the running board is between 1.5% and 2.8%.

[0034] Specific embodiment 1: The running board 10 is 1100mm long, 500mm wide, 12mm thick, the outermost arc height of the front and rear axes is 24mm, the outermost arc height of the left and right axes is 12mm, the ratio of the outermost arc height of the front and rear axes of the running board to the running board is 2.2%, and the ratio of the outermost arc height of the left and right axes of the running board to the running board is 2.4%.

[0035] Specific embodiment 2: The running board 10 is 2000mm long, 700mm wide, 15mm thick, the outermost arc height of the front and rear axes is 40mm, the outermost arc height of the left and right axes is 18mm, the ratio of the outermost arc height of the front and rear axes of the running board to the running board is 2.0%, and the ratio of the outermost arc height of the left and right axes of the running board to the running board is 2.5%.

[0036] When the ratio of the outermost arc height of the front and rear axes of the running board and the ratio of the outermost arc height of the left and right axes of the running board are close, that is, the difference is within 0.5%, the elastic deformation of the hyperbolic running board to the four sides when releasing the tension is close.

[0037] Specific embodiment 3: The running board 10 is 1000mm long, 380mm wide, 9mm thick, the outermost arc height of the front and rear axes is 12mm, the outermost arc height of the left and right axes is 8mm, the ratio of the outermost arc height of the front and rear axes of the running board to the running board is 1.2%, and the ratio of the outermost arc height of the left and right axes of the running board to the running board is 2.1%.

[0038] When the ratio of the outermost arc height of the front and rear axes of the running board to the running board is smaller than the ratio of the outermost arc height of the left and right axes of the running board to the running board, and the difference in the ratios is greater than 0.5%, the hyperbolic running board will mainly elastically deform in the left and right directions when the tension is released.

[0039] Specific embodiment 4: The running board 10 is 1600mm long, 600mm wide, 12mm thick, the outermost arc height of the front and rear axes is 40mm, the outermost arc height of the left and right axes is 9mm, the ratio of the outermost arc height of the front and rear axes of the running board to the running board is 2.5%, and the ratio of the outermost arc height of the left and right axes of the running board to the running board is 1.5%.

[0040] When the ratio of the outermost arc height of the front and rear axes of the running board to the running board is greater than the ratio of the outermost arc height of the left and right axes of the running board to the running board, and the difference in the ratios is greater than 0.5%, the hyperbolic running board will mainly elastically deform in the forward and backward directions when the tension is released.
