Description

Technical Field

[0001] This application relates to the field of training equipment, and more particularly to a treadmill running board assembly and a treadmill. Background Technology

[0002] Treadmills are a common piece of fitness equipment in homes and gyms. A treadmill consists of a running board assembly, a drive assembly that moves the running board assembly, and a control assembly that controls the drive assembly.

[0003] The running board assembly is placed on the ground, occupying a large area of ​​the ground and is inconvenient to store. Therefore, a foldable running board assembly has been developed. In the relevant technology, the front running board 10 and the rear running board 20 of the foldable running board assembly are hinged together, forming a hinge seam 70 between them. The running belt 60 is arranged in a ring and is fitted onto the front running board 10 and the rear running board 20.

[0004] Regarding the aforementioned technologies, the inventors believe that when users exercise on the running belt above the hinge joint between the front and rear running boards, they are prone to sprains due to the pits and depressions formed by the hinge joint and the front and rear running boards, and there is still room for improvement. Summary of the Invention

[0005] To prevent users from twisting their ankles when exercising on the upper side of the front and rear running boards, this application provides a treadmill running board assembly and a treadmill.

[0006] In a first aspect, this application provides a treadmill running board assembly, which adopts the following technical solution:

[0007] A treadmill running board assembly, comprising:

[0008] Front running board;

[0009] A rear running board, located behind the front running board; and

[0010] A hinge structure is provided at the splicing point on the lower side of the front running plate and the rear running plate. The hinge axis of the hinge structure is located on the lower surface of the front running plate and the hinge axis of the hinge structure is located on the lower surface of the rear running plate, so as to hinge the front running plate and the rear running plate together.

[0011] When the front running board and the rear running board are unfolded, the rear side of the front running board abuts against the front side of the rear running board; when the front running board and the rear running board are folded, the lower surface of the front running board and the lower surface of the rear running board are positioned opposite each other.

[0012] By adopting the above technical solution, gaps are less likely to form between the front and rear running boards when they are unfolded, thus making it less likely for users to twist their ankles when exercising on the upper side of the front and rear running boards, and improving the user experience of the running board components.

[0013] Optionally, the hinge structure includes:

[0014] The first base plate is fixed to the lower side of the front running plate;

[0015] The first hinge sleeve is fixed on the first base plate, and the axis of the first hinge sleeve is always located on the lower surface of the front running plate and the lower surface of the rear running plate.

[0016] The second base plate is fixed to the lower side of the rear running plate;

[0017] A second hinge sleeve is fixed to the second base plate, and the second hinge sleeve is concentrically arranged with the first hinge sleeve; and

[0018] A hinge shaft is sequentially inserted into the first hinge sleeve and the second hinge sleeve, and the hinge shaft is rotatably connected to both the first hinge sleeve and the second hinge sleeve.

[0019] By adopting the above technical solution, the front running board and the rear running board are hinged together, so that when the front and rear running boards are unfolded, the rear side of the front running board and the front side of the rear running board remain in contact, and gaps are not easily generated. This makes it less likely for users to twist their ankles when exercising on the upper side of the front and rear running boards, thus improving the user experience of the running board components.

[0020] Optionally, it also includes a retaining structure, which, when the front running board and the rear running board are deployed, keeps the rear side of the front running board in contact with the front side of the rear running board.

[0021] By adopting the above technical solution, when the front and rear running boards are deployed, the retaining structure provides a holding force for the front and rear running boards, so that the rear side of the front running board and the front side of the rear running board remain in contact, thereby making it less likely for gaps to form between the front and rear running boards and improving the user experience of the running board assembly.

[0022] Optionally, the retaining structure includes:

[0023] The first stud is hinged at one end to the front running plate;

[0024] The first adjusting sleeve is sleeved on the first stud and threadedly connected to the first stud.

[0025] The second stud, one end of which is hinged to the rear running plate; and

[0026] The second adjusting sleeve is sleeved on the second stud and threadedly connected to the second stud; the first adjusting sleeve is hinged to the second adjusting sleeve.

[0027] The first adjusting sleeve can rotate relative to the first stud, and the second adjusting sleeve can rotate relative to the second stud.

[0028] By adopting the above technical solution, when the front running board and the rear running board are unfolded, the angle between the first stud and the second stud is 180°, which provides a holding force for the front running board and the rear running board, so that the rear side of the front running board and the front side of the rear running board are kept in contact, thereby making it less likely for gaps to be generated between the front running board and the rear running board, and improving the user experience of the running board assembly.

[0029] Optionally, the retaining structure further includes:

[0030] A first hinge plate is sleeved on and rotatably connected to the first adjusting sleeve, and the first hinge plate can move with the first adjusting sleeve; and

[0031] The second hinge plate is sleeved on the second adjusting sleeve and rotatably connected to the second adjusting sleeve. The first hinge plate can move with the second adjusting sleeve. The second hinge plate is hinged to the first hinge plate. The first adjusting sleeve and the second adjusting sleeve are eccentrically arranged.

[0032] By adopting the above technical solution, the included angle between the first adjusting sleeve and the second adjusting sleeve can be 0° through the relative rotation of the first hinge plate and the second hinge plate, so as to facilitate folding the front running plate and the rear running plate together.

[0033] Optionally, the lower side of the front running plate is provided with a first receiving groove, and the lower side of the rear running plate is provided with a second receiving groove. When the front running plate and the rear running plate are unfolded, the retaining structure is housed in the space formed by the cooperation of the first receiving groove and the second receiving groove.

[0034] By adopting the above technical solution, the structure is kept within the space formed by the cooperation of the first and second receiving slots, which reduces the space occupied by the running plate assembly and saves space.

[0035] Optionally, the first adjusting sleeve is slidably connected to the first hinge plate along the axial direction. Two first elastic elements are sleeved on the first adjusting sleeve. The two first elastic elements are respectively disposed on both sides of the first hinge plate. Both ends of the first adjusting sleeve are provided with first limiting elements. The two first limiting elements make the two first elastic elements abut against the first adjusting sleeve.

[0036] The second adjusting sleeve is slidably connected to the second hinge plate along the axial direction. Two second elastic elements are sleeved on the second adjusting sleeve. The two second elastic elements are respectively located on both sides of the second hinge plate. The two ends of the second adjusting sleeve are provided with second limiting elements. The two second limiting elements keep the two second elastic elements in contact with the second adjusting sleeve.

[0037] By adopting the above technical solution, the buffering capacity of the retaining structure is improved, making the first stud, second stud, first adjusting sleeve and second adjusting sleeve of the retaining structure less prone to deformation during use, thereby improving the service life of the retaining structure.

[0038] Optionally, both the first elastic element and the second elastic element are compression springs.

[0039] Optionally, an elastic layer is laid on the upper side of the front running board and the rear running board.

[0040] By adopting the above technical solution, the elastic layer can reduce the impact vibration between the running belt, the front running board and the rear running board through its own elasticity, and at the same time, it can make adaptive deformation when the front running board and the rear running board are folded.

[0041] Secondly, this application provides a treadmill, which adopts the following technical solution:

[0042] A treadmill, characterized in that it includes a treadmill running board assembly as described above.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] This design minimizes gaps between the front and rear running boards when they are unfolded, reducing the risk of sprains for users exercising on the upper side of the boards and improving the user experience of the running board components. Attached Figure Description

Detailed Implementation

[0053] The following is in conjunction with the appendix Figure 3-7 This application will be described in further detail. The direction indicated by arrow x is the front side, and the opposite direction is the rear side.

[0054] This application discloses a treadmill running board assembly.

[0055] Example 1

[0056] Reference Figure 3 The treadmill running board assembly includes a front running board 10, a rear running board 20, and a hinge structure 30.

[0057] The front running plate 10 is located in front of the rear running plate 20, and the front running plate 10 and the rear running plate 20 are hinged together by a hinge structure 30. Specifically, the hinge structure 30 includes a first base plate 31, a first hinge sleeve 32, a second base plate 33, a second hinge sleeve 34, and a hinge shaft 35. The first base plate 31 is fixed to the lower side of the front running plate 10, and the first hinge sleeve 32 is fixed to the rear side of the first base plate 31. The axis of the first hinge sleeve 32 is always located on the lower surface of the front running plate 10 and the rear running plate 20. The second base plate 33 is fixed to the lower side of the rear running plate 20, and the second hinge sleeve 34 is fixed to the front side of the first base plate 31. The axis of the second hinge sleeve 34 is always located on the lower surface of the front running plate 10 and the rear running plate 20, and the second hinge sleeve 34 and the first hinge sleeve 32 are concentrically arranged. A receiving groove 12 is provided on the lower side of the connection between the front running plate 10 and the rear running plate 20. The first hinge sleeve 32 and the second hinge sleeve 34 are partially disposed in the receiving groove 12. The hinge shaft 35 is sequentially inserted into the first hinge sleeve 32 and the second hinge sleeve 34. The axis of the hinge shaft 35 is always located on the lower surface of the front running plate 10 and the rear running plate 20. The hinge shaft 35 is rotatably connected to the first hinge sleeve 32 and the second hinge sleeve 34 to hinge the front running plate 10 and the rear running plate 20 together.

[0058] When the front running board 10 and the rear running board 20 are unfolded, the rear side of the front running board 10 abuts against the front side of the rear running board 20. When the front running board 10 and the rear running board 20 are folded, the lower surface of the front running board 10 and the lower surface of the rear running board 20 are positioned opposite each other.

[0059] Reference Figure 3 and Figure 4 To ensure that the rear side of the front running plate 10 and the front side of the rear running plate 20 remain in contact when the front running plate 10 and the rear running plate 20 are deployed, the treadmill running plate assembly also includes a retaining assembly. Specifically, the retaining assembly includes a first stud 41, a first adjusting sleeve 42, a second stud 43, and a second adjusting sleeve 44. The first stud 41 is hinged to the lower side of the front running plate 10, and the first adjusting sleeve 42 is fitted onto the first stud 41, with the first adjusting sleeve 42 threadedly connected to the first stud 41. The second stud 43 is hinged to the lower side of the rear running plate 20, and the second adjusting sleeve 44 is fitted onto the second stud 43, with the second adjusting sleeve 44 threadedly connected to the second stud 43. The second adjusting sleeve 44 is eccentrically set with the first adjusting sleeve 42. The front end of the second adjusting sleeve 44 is fixed with a second hinge block 443, and the rear end of the first adjusting sleeve 42 is fixed with a first hinge block 423. The first hinge block 423 and the second hinge block 443 are hinged through a hinge shaft 35. The first adjusting sleeve 42 and the second adjusting sleeve 44 are concentrically set.

[0060] When the front running plate 10 and the rear running plate 20 are unfolded, the retaining structure 40 can be located below the hinge axis 35 of the hinge structure 30 or above the hinge axis 35 of the hinge structure 30. When the retaining structure 40 is located above the hinge axis 35 of the hinge structure 30, a first receiving groove 11 is provided on the lower side of the front running plate 10, and a second receiving groove 21 is provided on the lower side of the rear running plate 20. When the front running plate 10 and the rear running plate 20 are unfolded, the first receiving groove 11 and the second receiving groove 21 are connected, and the retaining structure 40 is housed in the space formed by the cooperation of the first receiving groove 11 and the second receiving groove 21.

[0061] When the retaining structure 40 is located above the hinge axis 35 of the hinge structure 30, the retaining structure 40 provides tension, ensuring that the rear side of the front running plate 10 abuts against the front side of the rear running plate 20, making it less likely for a hinge seam 70 to form between the front running plate 10 and the rear running plate 20, thus preventing the front running plate 10 and the rear running plate 20 from vibrating significantly when the user runs on them. When the retaining structure 40 is located below the hinge axis 35 of the hinge structure 30, the retaining structure 40 provides push-out force, ensuring that the rear side of the front running plate 10 abuts against the front side of the rear running plate 20, making it less likely for a hinge seam 70 to form between the front running plate 10 and the rear running plate 20, thus preventing the front running plate 10 and the rear running plate 20 from vibrating significantly when the user runs on them.

[0062] To reduce the energy transferred to the front running board 10 and the rear running board 20 during running, an elastic layer 50 is laid on the upper side of the front running board 10 and the rear running board 20. The elastic layer 50 is bonded to the front running board 10 and the rear running board 20 with strong adhesive. The elastic layer 50 can reduce the impact vibration between the running belt 60, the front running board 10 and the rear running board 20 through its own elasticity. When the front running board 10 and the rear running board 20 are folded, the elastic layer 50 stretches.

[0063] The implementation principle of Example 1 is as follows: The front running board 10 and the rear running board 20 are hinged together by the hinge structure 30, so that when the front running board 10 and the rear running board 20 are unfolded, the rear side of the front running board 10 abuts against the front side of the rear running board 20, and the hinge seam 70 is not easily formed, so that the user is less likely to twist when moving on the upper side of the front running board 10 and the rear running board 20. The retaining structure 40 provides a retaining force for the front running board 10 and the rear running board 20 when unfolded, so that the rear side of the front running board 10 and the front side of the rear running board 20 remain in contact, improving the stability of the front running board 10 and the rear running board 20 during use.

[0064] Example 2

[0065] Reference Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that the first adjusting sleeve 42 and the second adjusting sleeve 44 are eccentrically arranged, and the retaining structure 40 also includes a first hinge plate 45 and a second hinge plate 46. The first hinge plate 45 is sleeved on the first adjusting sleeve 42, and the first adjusting sleeve 42 is rotatably connected to the first hinge plate 45 in the circumferential direction. Both ends of the first adjusting sleeve 42 are provided with first limiting members 422, which are nuts. The first limiting members 422 are sleeved on the first adjusting sleeve 42 and threadedly connected to the first adjusting sleeve 42. The two first limiting members 422 are located on both sides of the first hinge plate 45 to limit the first hinge plate 45, so that the first hinge plate 45 moves with the first adjusting sleeve 42 along the axial direction of the first adjusting sleeve 42.

[0066] The second hinge plate 46 is sleeved on the second adjusting sleeve 44, and the second adjusting sleeve 44 is rotatably connected to the second hinge plate 46 in the circumferential direction. Both ends of the second adjusting sleeve 44 are provided with second limiting members 442, which are nuts. The second limiting members 442 are sleeved on the second adjusting sleeve 44 and threadedly connected to it. The two second limiting members 442 are located on both sides of the second hinge plate 46 to limit the movement of the second hinge plate 46, allowing it to move axially along the second adjusting sleeve 44.

[0067] Reference Figure 6 and Figure 7The first hinge plate 45 and the second hinge plate 46 are hinged together. Specifically, both the first hinge plate 45 and the second hinge plate 46 are provided with through holes 451, and hinge pins 453 are provided through the through holes 451. Limiting rings 454 are threaded to both ends of the hinge pins 453. The through holes 451 and the through holes of the first hinge plate 45 and the second hinge plate 46 are provided with grooves 452. The limiting rings 454 are embedded in the grooves 452 and can rotate relative to the first hinge plate 45 and the second hinge plate 46.

[0068] To cushion the impact force applied by the user to the front running plate 10 and the rear running plate 20, two first elastic elements 421 are fitted onto the first adjusting sleeve 42. The first elastic elements 421 can be either compression springs. The two first elastic elements 421 are located on both sides of the first hinge plate 45, between the first limiting member 422 and the first hinge plate 45. Two second elastic elements 441 are fitted onto the second adjusting sleeve 44. The second elastic elements 441 can also be either compression springs. The two second elastic elements 441 are located on both sides of the second hinge plate 46, between the second limiting member 442 and the second hinge plate 46.

[0069] The implementation principle of Embodiment 2 is as follows: Compared with Embodiment 1, the retaining structure 40 in this embodiment is easier to fold and store. The angle between the first stud 41 and the second stud 43 can be 0° through the hinge of the first hinge plate 45 and the second hinge plate 46. In addition, the provision of the first elastic member 421 and the second elastic member 441 further improves the buffering capacity of the retaining structure 40, making the retaining structure 40 less prone to deformation and damage due to long-term use, thereby improving the service life of the retaining structure 40.
