Technical Field

[0001] The present disclosure relates to the technical field of fitness equipment, and particularly to a running board and a treadmill. Background Art

[0002] With the improvement of people's living standards and the enhancement of health awareness, treadmills have become common fitness equipment in places such as homes and gyms, providing people with a convenient and efficient way of exercise.

[0003] In existing folding treadmills, their structures are often more compact and simplified, resulting in a lack of sufficient structural support at the gap between the front running board and the rear running board. As a result, the stability of the treadmill decreases, affecting the exercise effect and safety of users, and reducing the user experience. Summary of the Utility Model

[0004] The present disclosure provides a running board and a treadmill to at least solve the above technical problems existing in the prior art.

[0005] According to a first aspect of the present disclosure, a running board is provided, including: a first running board; a second running board disposed along the length direction of the first running board; an endless running belt sleeved on the first running board and the second running board with a gap and capable of transmitting relative to the first running board and the second running board; and an arc-shaped component disposed inside the endless running belt and between the first running board and the second running board, at least part of the outer periphery of the arc-shaped component being flush with or protruding relative to the upper surfaces of the first running board and the second running board, and the arc-shaped component being disposed along the width direction of the first running board and the second running board.

[0006] In an implementable embodiment, the support component includes a bracket, the first running board and the second running board are fixed by the bracket, and the arc-shaped component is connected to the bracket.

[0007] In an implementable embodiment, the arc-shaped component includes a cross shaft, and a gap is formed between the outer periphery of the cross shaft and the endless running belt.

[0008] In an implementable embodiment, the arc-shaped component includes a cross shaft, and the outer periphery of the cross shaft is tangent to the endless running belt.

[0009] In an implementable embodiment, both ends of the cross shaft are tightly connected to the bracket.

[0010] In an implementable embodiment, the arc-shaped component further includes a rotating shaft, the rotating shaft is fixed to the end of the cross shaft, and the rotating shaft is rotatably connected to the bracket.

[0011] In one possible implementation, the arc-shaped component includes an arc-shaped member having an arc portion, at least a part of the outer periphery of the arc portion being flush with or protruding relative to the upper surfaces of the first running board and the second running board, and both ends of the arc-shaped member being fixedly connected to the bracket.

[0012] In one possible implementation, an elastic layer is provided on the surface of the horizontal shaft.

[0013] In one possible implementation, an elastic layer is provided on the surface of the arc portion.

[0014] According to a second aspect of the present disclosure, a treadmill is provided, which includes a driving component and a running platform as described in any one of the above possible implementations. The driving component is disposed inside the endless running belt and is used to drive the endless running belt to transmit.

[0015] In the present disclosure, since an arc-shaped component is provided between the first running board and the second running board of the running platform, not only the height difference formed by the gap between the first running board and the second running board is overcome, but also the role of supporting the endless running belt is played, ensuring the stability of the endless running belt during operation.

Detailed implementation manners

[0029] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0030] The embodiments of the present disclosure will be described in detail below in conjunction with the drawings.

[0031] Refer to Figure 1 and Figure 2As shown in the figure, a treadmill according to an exemplary embodiment of the present disclosure includes a first running board 1, a second running board 2, a loop running belt 3, and an arc-shaped component 4. The second running board 2 is arranged along the length direction of the first running board 1. The loop running belt 3 is sleeved on the first running board 1 and the second running board 2 with a gap and can be driven relative to the first running board 1 and the second running board 2. The arc-shaped component 4 is arranged inside the loop running belt 3 and between the first running board 1 and the second running board 2. At least part of the outer periphery of the arc-shaped component 4 is flush with the upper surfaces of the first running board 1 and the second running board 2 or protrudes relative to the upper surfaces of the first running board 1 and the second running board 2. The arc-shaped component 4 is arranged along the width direction of the first running board 1 and the second running board 2.

[0032] In this embodiment, the first running board 1 is defined as the front running board, and the second running board 2 is defined as the rear running board. It can be understood that the front, rear, left, right, up, and down directions in the present disclosure are based on the directions when the treadmill is in normal use. For example, the second running board 2 is arranged behind the first running board 1 and coplanar with the first running board 1. The upper surfaces of the first running board 1 and the second running board 2 are the surfaces on the side away from the ground. Correspondingly, the lower surfaces of the second running board 2 and the second running board 2 are the surfaces on the side close to the ground. The height direction of the treadmill is the extension of the up and down direction, that is, the vertical direction. There is a certain gap between the loop running belt 3 and the first running board 1 and the second running board 2, and it is not in close contact with the first running board 1 and the second running board 2. This gap helps to reduce the friction between the loop running belt 3 and the first running board 1 and the second running board 2, so as to improve the durability of the treadmill. The loop running belt 3 can be driven along the surfaces of the first running board 1 and the second running board 2, that is, when the user is running, the loop running belt 3 can move smoothly and drive the user to exercise. The arc-shaped component 4 is arranged between the first running board 1 and the second running board 2. At least part of the outer periphery of the arc-shaped component 4 includes an arc section, and the arc section is arranged upward. The top of the arc section is flush with the upper surfaces of the first running board 1 and the second running board 2, or the top of the arc section is within the gap between the loop running belt 3 and the first running board 1 and the second running board 2 and higher than the upper surfaces of the first running board 1 and the second running board 2, so as to ensure that when the human foot steps on the loop running belt 3 above the arc-shaped component 4, the arc-shaped component 4 contacts the loop running belt 3 and plays a supporting role for the human body.

[0033] Therefore, since the arc-shaped component 4 is arranged between the first running board 1 and the second running board 2 of the treadmill, it not only overcomes the height difference formed by the gap between the first running board 1 and the second running board 2, but also plays a role in supporting the loop running belt 3, ensuring the stability of the loop running belt 3 during operation. That is, when the human foot steps on the loop running belt 3 and makes the loop running belt 3 contact the arc-shaped component 4, the friction between the loop running belt 3 and the arc-shaped component 4 is reduced, and the use efficiency, comfort, and service life of the treadmill are improved.

[0034] In an implementable embodiment, the treadmill further includes a support assembly 5. The support assembly 5 includes a bracket 51. The first running board 1 and the second running board 2 are fixed by the bracket 51, and the arc assembly 4 is connected to the bracket 51.

[0035] In this embodiment, the bracket 51 includes two side frames which are oppositely arranged on the left and right sides of the treadmill respectively, and the endless running belt 3 is located between the two side frames. The support assembly 5 includes a plurality of cross beams 52 which are distributed on and fixedly connected to the lower surfaces of the first running board 1 and the second running board 2. The two ends of the cross beam 52 are respectively fixed to the two side frames. At least one end of the arc assembly 4 is connected to the bracket 51, and the connection method can be a fixed connection or a rotational connection, which can be adaptively designed according to actual needs.

[0036] Refer to Figure 3 and Figure 8 As shown, in an implementable embodiment, the arc assembly 4 includes a transverse shaft 41, and a gap is formed between the outer periphery of the transverse shaft 41 and the endless running belt 3.

[0037] Specifically, in an implementable embodiment, the two ends of the transverse shaft 41 are tightly connected to the bracket 51.

[0038] In this embodiment, the transverse shaft 41 is in a cylindrical shape. The top end of the outer periphery of the transverse shaft 41 is flush with the upper surfaces of the first running board 1 and the second running board 2, or the top end of the outer periphery of the transverse shaft 41 is within the gap between the endless running belt 3 and the first running board 1 and the second running board 2 and is higher than the upper surfaces of the first running board 1 and the second running board 2, so as to ensure that when a person's foot steps on the endless running belt 3 above the arc assembly 4, the arc assembly 4 contacts the endless running belt 3 and plays a supporting role on the human body. At least one of the two ends of the transverse shaft 41 is tightly connected to the side frame. Specifically, a connecting portion 42 is provided at the shaft end of the transverse shaft 41, and the connecting portion 42 is locked to the side frame by a fastener 6. It can be understood that the connecting portion 42 can also be fixed to the side frame by means of snap connection, pin connection or magnetic attraction connection, etc., and will not be elaborated here.

[0039] Refer to Figure 3 and Figure 9 As shown, in an implementable embodiment, the arc assembly 4 includes a transverse shaft 41, and a gap is formed between the outer periphery of the transverse shaft 41 and the endless running belt 3. The arc assembly 4 further includes a rotating shaft 43 which is fixed to the end of the transverse shaft 41, and the rotating shaft 43 is rotatably connected to the bracket 51.

[0040] In this embodiment, a rotating shaft 43 is fixed to at least one end of both ends of the horizontal shaft 41. The rotating shaft 43 is rotatably connected to the side frame, so that the rolling friction is changed between the annular running belt 3 and the arc-shaped component 4, further reducing the resistance. When the user steps on the annular running belt 3 above the horizontal shaft 41, the horizontal shaft 41 can rotate following the running belt. It can be understood that the arc-shaped component 4 can also be provided with a damping adjustment structure for the user to adjust the rolling sensitivity of the horizontal shaft 41, improving the applicability and durability of the treadmill. Preferably, the rotating shaft 43 is also connected with a driving member, and the driving member can drive the rotating shaft 43 to rotate automatically, and drive the horizontal shaft 41 and the annular running belt 3 to rotate synchronously by setting to drive the rotating shaft 43.

[0041] Referring to Figure 4 and Figure 8 As shown, in an implementable embodiment, the arc-shaped component 4 includes a horizontal shaft 41, and the outer periphery of the horizontal shaft 41 is tangent to the annular running belt 3.

[0042] Specifically, in an implementable embodiment, both ends of the horizontal shaft 41 are tightly connected to the bracket 51.

[0043] In this embodiment, the horizontal shaft 41 is in a cylindrical shape. The outer periphery of the horizontal shaft 41 is at least tangent to the annular running belt 3 on one side of the upper surfaces of the first running board 1 and the second running board 2, that is, the annular running belt 3 on one side of the upper surfaces of the first running board 1 and the second running board 2 is tangent to the outer periphery of the horizontal shaft 41, and there is a gap (not shown in the figure) between the annular running belt 3 on one side of the lower surfaces of the first running board 1 and the second running board 2 and the outer periphery of the horizontal shaft 41; or, the annular running belts 3 on the upper and lower surfaces of the first running board 1 and the second running board 2 are both tangent to the outer periphery of the horizontal shaft 41, so as to provide sufficient support for the human body. At least one end of both ends of the horizontal shaft 41 is tightly connected to the side frame. Specifically, a connecting portion 42 is provided at the shaft end of the horizontal shaft 41, and the connecting portion 42 is locked to the side frame through a fastener 6. It can be understood that the connecting portion 42 can also be fixed to the side frame by means of snap connection, pin connection or magnetic attraction connection, etc., and will not be elaborated here.

[0044] Referring to Figure 4 and Figure 9 As shown, in an implementable embodiment, the arc-shaped component 4 includes a horizontal shaft 41, and the outer periphery of the horizontal shaft 41 is tangent to the annular running belt 3. The arc-shaped component 4 further includes a rotating shaft 43, and the rotating shaft 43 is fixed to the end of the horizontal shaft 41, and the rotating shaft 43 is rotatably connected to the bracket 51.

[0045] In this embodiment, a rotating shaft 43 is fixed to at least one end of the two ends of the horizontal shaft 41. The rotating shaft 43 is rotatably connected to the side frame, so that the rolling friction is changed between the annular running belt 3 and the arc-shaped component 4, further reducing the resistance. When the user steps on the annular running belt 3 above the horizontal shaft 41, the horizontal shaft 41 can rotate following the running belt. It can be understood that the arc-shaped component 4 can also be provided with a damping adjustment structure for the user to adjust the rolling sensitivity of the horizontal shaft 41, improving the applicability and durability of the treadmill. Preferably, the rotating shaft 43 is further connected with a driving member, and the driving member can drive the rotating shaft 43 to rotate automatically, and drive the horizontal shaft 41 and the annular running belt 3 to rotate synchronously by setting the driving of the rotating shaft 43.

[0046] Referring to Figure 6 and Figure 8 As shown, in an implementable embodiment, the arc-shaped component 4 includes an arc-shaped member 40. The arc-shaped member 40 has an arc-shaped portion. At least part of the outer periphery of the arc-shaped portion is flush with the upper surfaces of the first running board 1 and the second running board 2 or protrudes relative to the upper surfaces of the first running board 1 and the second running board 2. Both ends of the arc-shaped member 40 are tightly connected to the bracket 51.

[0047] In this embodiment, the arc-shaped portion can be circular arc-shaped, arched or a more complex curve shape. The arc-shaped member 40 only needs to ensure that the upward side has an arc-shaped portion. The shape of the portion other than the arc-shaped portion on the arc-shaped member 40 is not limited, and can be, including but not limited to, square, circular or irregular shape, etc. The top end of the arc-shaped portion is flush with the upper surfaces of the first running board 1 and the second running board 2; or, the top end of the arc-shaped portion is within the gap between the annular running belt 3 and the first running board 1 and the second running board 2 and is higher than the upper surfaces of the first running board 1 and the second running board 2; or, the top end of the arc-shaped portion is tangent to the annular running belt 3 on one side of the upper surfaces of the first running board 1 and the second running board 2, so as to ensure that when the human foot steps on the annular running belt 3 above the arc-shaped component 4, the arc-shaped component 4 contacts the annular running belt 3 and plays a supporting role for the human body. At least one end of both ends of the arc-shaped member 40 is tightly connected to the side frame. Specifically, a connecting portion 42 is provided at the shaft end of the arc-shaped member 40, and the connecting portion 42 is locked to the side frame through a fastener 6. It can be understood that the connecting portion 42 can also be fixed to the side frame by means of snap connection, pin connection or magnetic attraction connection, etc., and will not be elaborated here.

[0048] Referring to Figure 5 As shown, in an implementable embodiment, an elastic layer 44 is provided on the surface of the horizontal shaft 41.

[0049] In this embodiment, the elastic layer 44 can be an annular elastic layer 44 wrapped around the outer periphery of the horizontal shaft 41, or an elastic layer 44 with elastic protrusions wrapped around the outer periphery of the horizontal shaft 41. These protrusions can be dot-shaped, strip-shaped or other shapes, which can play a role in relaxing muscles and relieving fatigue when a person steps on it. The elastic layer 44 is usually made of a highly elastic material, such as rubber or silica gel, etc., to ensure its good massage effect and durability. It should be noted that when the elastic layer 44 is provided on the outer periphery of the horizontal shaft 41, the maximum size of the elastic layer 44 is tangent to the annular running belt 3.

[0050] Referring to Figure 7 As shown, in an implementable embodiment, an elastic layer 44 is provided on the surface of the arc portion of the arc-shaped member 40.

[0051] In this embodiment, the elastic layer 44 provided on the surface of the arc portion can be provided with elastic protrusions. These protrusions can be dot-shaped, strip-shaped or other shapes, which can play a role in relaxing muscles and relieving fatigue when a person steps on it. The elastic layer 44 is usually made of a highly elastic material, such as rubber or silica gel, etc., to ensure its good massage effect and durability. It should be noted that when the elastic layer 44 is provided on the surface of the arc portion, the maximum size of the elastic layer 44 is tangent to the annular running belt 3.

[0052] The present disclosure also provides a treadmill, including a drive assembly, and further including a running platform in any of the above implementable embodiments. The drive assembly is disposed inside the annular running belt 3 for driving the annular running belt 3 to transmit.

[0053] Referring again to Figure 2As shown, in this embodiment, the driving assembly includes a first roller 7, a second roller 8 and a power member. The first roller 7 is disposed at the front end of the first running board 1, and the second roller 8 is disposed at the rear end of the second running board 2. The endless running belt 3 is wrapped around at least a part of the outer circumferences of the first roller 7 and the second roller 8. The power member is used to deliver a driving force to the first roller 7 and / or the second roller 8, so that the first roller 7 and / or the second roller 8 drives the endless running belt 3 to move. Specifically, the power member can provide a driving force to the first roller and the second roller 8 to make them rotate synchronously; or, the power member can only provide a driving force to the first roller 7 to make it rotate, and the second roller 8 can follow the first roller 7 passively under the cooperation of the first roller 7 and the endless running belt 3. Since the treadmill of the present disclosure includes a running platform, an arc-shaped assembly 4 is provided between the first running board 1 and the second running board 2 of the running platform, which not only overcomes the height difference formed by the gap between the first running board 1 and the second running board 2, but also plays a role in supporting the endless running belt 3, ensuring the stability of the endless running belt 3 during operation. That is, when a person steps on the endless running belt 3 and makes the endless running belt 3 contact the arc-shaped assembly 4, the friction between the endless running belt 3 and the arc-shaped assembly 4 is reduced, and the use efficiency, comfort and service life of the running platform are improved.
