Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fitness equipment, in particular to a light-weight structure design of a fitness equipment with a running track. BACKGROUND

[0002] In the current fitness equipment market, as a popular indoor fitness device, treadmills are constantly developing in a more optimized direction. The traditional treadmills have many aspects to be improved in design, especially in the aspect of light weight. On the one hand, many treadmills adopt an overall, heavy running track structure. In order to ensure that the treadmill has sufficient load-bearing capacity, the running track structure of the treadmill uses high-strength materials, which leads to the excessive weight of the whole machine. This not only makes the treadmill extremely inconvenient to move and transport, but also cannot meet the user's demand for flexible placement in different home environments. In addition, from the perspective of production cost, the use of a large amount of materials undoubtedly increases the production cost, resulting in a high product price, which affects the willingness of consumers to purchase to some extent.

[0003] The running track frame of the traditional treadmill is mostly made of solid plate or integrally welded structure. In order to resist the vertical impact force and lateral torque when the user steps on, such design has to rely on the material thickness and overall rigidity, which leads to the weight of a single running track generally exceeding 30 kg, accounting for more than 60% of the weight of the whole machine.

[0004] In recent years, with the increasing requirements of consumers for the convenience, practicality and economy of fitness equipment, light weight design has become a key trend in the development of treadmills. Most of the existing technology designs adopt light and high-strength materials such as aluminum alloy to reduce the weight of the treadmill. However, light weight materials mean that the material cost of the treadmill increases, and the welding process requires higher, which leads to the increase of the terminal selling price and makes it difficult for the mass market to accept. Another solution of the treadmill realizes light weight by thinning the material thickness, but this design sacrifices the load-bearing capacity of the treadmill.

[0005] In other words, there is still a lack of a treadmill product on the market that can significantly reduce weight and production cost while ensuring high load-bearing performance, and the structure design is more scientific and reasonable. SUMMARY

[0006] The purpose of the present application is to provide a light-weight structure design of a fitness equipment with a running track that can significantly reduce weight and production cost while ensuring high load-bearing performance.

[0007] To achieve the above object, the technical scheme provides a walking / running machine with a lightweight structure, which comprises a treadmill frame, wherein the treadmill frame comprises a main frame and at least one load-bearing reinforcing member arranged on the main frame; a rolling assembly, wherein the rolling assembly comprises a front roller arranged at the front end of the treadmill frame, a rear roller arranged at the rear end of the treadmill frame, and a driving member for driving the front roller and / or the rear roller; a running board arranged on the load-bearing reinforcing member and the main frame; and a running belt arranged on the running board and around the rolling assembly.

[0008] Compared with the prior art, the technical scheme has the following characteristics and beneficial effects: The walking / running machine provided by the scheme adopts an assembled treadmill frame, which significantly reduces the weight of the whole machine while ensuring high load-bearing performance, meets the use requirements of users with different weights, and is convenient for single-person carrying and moving, thereby improving the flexibility of the equipment.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0021] Those skilled in the art should understand that in the disclosure of the present application, the orientations or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as a limitation on the present application.

[0022] Embodiment one As shown in Figure 1 and Figure 2 , the present application provides a lightweight structure design of a fitness equipment with a treadmill, comprising: a treadmill frame 10, wherein the treadmill frame 10 comprises a main frame 11 and at least one load bearing reinforcing piece 12 arranged on the main frame 11; A rolling assembly 40, wherein the rolling assembly 40 comprises a front roller 41 arranged at the front end of the treadmill frame 10, a rear roller 42 arranged at the rear end of the treadmill frame 10, and a driving member 43 driving the front roller 41 and / or the rear roller 42; A running deck 20 arranged on the load-reinforcing member 12 and the main frame 11; A running belt 30 arranged on the running deck 20 and around the rolling assembly 40.

[0023] The treadmill provided by the present application refers to a walking machine, a running machine or other fitness equipment for walking and running training.

[0024] It should be noted that the treadmill frame 10 of the present application adopts the assembly mode of the main frame 11 and the load-reinforcing member 12 as the load-reinforcing member of the running deck 20, and is different from the traditional complete treadmill or integrally formed treadmill which needs to be made of high-strength materials as a whole. The treadmill frame provided by the present application greatly reduces the material consumption of the walking machine treadmill, and reduces the weight and manufacturing cost of the walking machine treadmill while providing high load-bearing performance.

[0025] As shown in FIGS. Figure 3 and Figure 4 The main frame 11 of the present application comprises frame main beams 111 arranged on both sides and at least one frame connecting member 112 connecting the frame main beams 111, and at least one load-reinforcing member 12 is arranged on the frame main beams 111 on both sides, and the running deck 20 is arranged above the frame main beams 111 and the load-reinforcing member 12. That is, the frame main beams 111 of the main frame 11 of the present application are used to support the running deck 20, and the frame main beams 111 on both sides are connected through the at least one load-reinforcing member 12 and the frame connecting member 12.

[0026] The treadmill frame 10 provided by the present application is used to bear the pressure on the running deck 20. Specifically, when the trainer stands on the running deck 20 for training, the pressure generated by the trainer stepping on the running deck 20 is first dispersed by the running deck 20 to the frame main beams 111 on both sides and the load-reinforcing member 12, and the load-reinforcing member 12 then transmits the load-bearing pressure to the frame main beams 111 on both sides. Since the frame main beams 111 on both sides are connected through the frame connecting member 112, the pressure on the frame main beams 111 can be evenly dispersed to the entire main frame 11, thereby enabling the treadmill frame 10 to provide a high-strength load-bearing surface.

[0027] In order to improve the load-bearing capacity of the main frame 11, the frame main beams 111 and the frame connecting member 112 are integrally formed, which has the advantage of eliminating the mechanical weakness of the connection nodes on the main frame 11. In other words, the main frame 11 of the present application forms an integrally formed structure with a seamless structure through overall casting (such as aluminum alloy die casting) or bending process (steel material), so that the force is more smoothly transmitted from the frame main beams 111 to the frame connecting member 112.

[0028] In some embodiments, at least one frame connecting member 112 is arranged on the bottom surface of the frame girder 111, and the load-bearing reinforcement 12 is arranged on the top surface of the frame girder 111 for bearing the running plate 20.

[0029] In some embodiments, the frame girders 111 on both sides are arranged in parallel, and the at least one frame connecting member 112 is arranged vertically connecting the frame girders 111 on both sides, i.e. the main frame 11 forms a H-shaped structure. The parallel frame girders 111 can disperse the longitudinal load, and the vertically connected frame connecting member 112 can convert the lateral force into overall tension. The impact force when the user steps on can be quickly transmitted to the ground, reducing local stress concentration.

[0030] In some embodiments, the at least one frame connecting member 112 of the present scheme is designed as a grid structure. Specifically, the bottom surface of the frame connecting member 112 is parallel to the bottom surface of the frame girder 111, and the grid strips are arranged in the bottom surface. The two ends of the grid strips are connected to the inner side walls of the frame girders 111 on both sides. The grid strips of the frame connecting member 112 of the present scheme form a hollow structure by crossing or parallel arrangement, which can reduce the material usage compared with the solid plate connecting member while ensuring the overall rigidity. The design of the grid structure is more suitable for injection molding or stamping process mass production.

[0031] In some embodiments, the at least two frame connecting members 112 are arranged in parallel at intervals, and the plurality of frame connecting members 112 are respectively arranged at the head end, the middle end and the tail end of the frame girder 111, so as to more stably connect the frame girders 111 on both sides. In a specific embodiment, the at least four frame connecting members 112 connect the frame girders 111 on both sides.

[0032] In a specific embodiment of the present scheme, the frame connecting member 112 on the main frame 11 includes a first frame connecting member and a second frame connecting member. The first frame connecting member is designed with irregular grid strips, and the second frame connecting member is designed with regular grid strips. That is, the first frame connecting member 1121 is provided with a plurality of grids of different sizes, and the second frame connecting member 1122 is provided with a plurality of grids of the same size.

[0033] In order to realize the connection with the running plate 20 and the load-bearing reinforcement 12, the top surface of each frame girder 111 forms a running plate mounting area 1113 and a load-bearing reinforcement mounting area 1114, and the load-bearing reinforcement mounting area 1114 is arranged in a recessed manner relative to the running plate mounting area 1113. The load-bearing reinforcement 12 is mounted on the load-bearing reinforcement mounting area 1114, the running plate 20 is mounted on the running plate mounting area 1113, and the running plate 20 is arranged on the upper surface of the load-bearing reinforcement 12.

[0034] In some embodiments, the load-bearing reinforcement mounting area 1114 is arranged close to and penetrates the inner side wall of the frame main beam 111, and the thickness of the load-bearing reinforcement mounting area 1114 matches the thickness of the load-bearing reinforcement 12, which has the advantage that when the load-bearing reinforcement 12 is arranged on the load-bearing reinforcement mounting area 1114, the top surface of the load-bearing reinforcement 12 is flush with the running board mounting area 1113, so that the running board 20 can be placed flat on the running board mounting area 1113.

[0035] In some embodiments, the load-bearing reinforcement 12 is connected to the frame main beam 11 by bolts, i.e., the load-bearing reinforcement 12 is connected to the load-bearing reinforcement mounting area 1114 by bolts.

[0036] In an embodiment of the present scheme, at least one load-bearing reinforcement 12 is assembled on the top surface of the frame main beam 111, at least one frame connecting member 112 is connected to the top surface of the frame main beam 111, and the load-bearing reinforcement 12 and the frame connecting member 112 are arranged alternately, which can disperse the load and avoid stress concentration, while efficiently utilizing the space, maintaining a compact structure and improving the overall stability.

[0037] As shown in Figure 3 The load-bearing reinforcement 12 of the treadmill frame 10 of the present scheme includes first load-bearing reinforcements 121 and second load-bearing reinforcements 122 arranged in parallel and spaced apart, wherein the first load-bearing reinforcements 121 and the second load-bearing reinforcements 122 are arranged at different positions of the running board mounting area 1113, respectively, to better withstand the pressure from the running board 20. Further, the second load-bearing reinforcements 122 are arranged at the middle position of the entire running board frame 10 to serve as running board load-bearing reinforcements.

[0038] It should be noted that the lengths of the running board mounting areas 1113 on the frame main beams 111 on both sides are not necessarily the same, but the load-bearing reinforcement mounting areas 1114 on the frame main beams 111 on both sides are arranged oppositely.

[0039] In some embodiments, the running board 20 is fixedly connected in the running board mounting area 1113. In a specific embodiment of the present scheme, the running board 20 is fixedly connected in the running board mounting area 1113 by bolts.

[0040] It should be noted that in some embodiments, the main frame 11 has a self-treadmill belt refueling assembly parallel to the load-bearing reinforcement 12.

[0041] To enhance the aesthetics of the running deck frame 10, the treadmill frame 11 of this embodiment further includes a frame cover 13 that covers the frame main beam running deck 20. The frame cover 13 covers the running deck 20 located in the running deck mounting area 1113 of the treadmill frame 11. Specifically, when the running deck 20 is installed in the running deck mounting area 1113, the frame cover 13 covers the running deck 20 and is positioned relative to the running deck mounting area 1113.

[0042] In order to achieve the connection with the rolling assembly 40, as Figure 5 As shown, a recessed component installation area 1112 is formed on the bottom surface of each frame main beam 111. The recessed component installation area 1112 can embed components such as circuit boards, drive motors, and power supplies into the interior of the frame main beam 111, avoiding space occupation caused by protruding components (reducing the overall height by 5-8mm), while forming physical protection (isolating ground bumps and dust intrusion), reducing the probability of component damage due to external forces; in addition, the hidden installation makes the bottom surface of the frame main beam 111 flat, more stable when placed, and avoids the risk of short circuit caused by direct contact between components and the ground.

[0043] Furthermore, the bottom surface of the frame main beam 111 is provided with load-bearing reinforcement ribs 1111, and the load-bearing reinforcement ribs 1111 are distributed along the length direction of the frame main beam 111 or around the component installation area 1112. The advantage of this is that the load-bearing capacity of the frame main beam 111 can be enhanced.

[0044] like Figure 5 As shown, the front roller 41 of the rolling assembly 40 is disposed at the front end of the treadmill frame 10, and the rear roller 42 is disposed at the rear end of the treadmill frame 10. The front roller 41 is driven by a driving member 43 to achieve active rotation. Specifically, the treadmill belt 30 is sleeved on the front roller 41 and the rear roller 43. The front roller 41 is driven by the driving member 43 to achieve active rotation, thereby driving the treadmill belt 30 to rotate. The rotation of the treadmill belt 30 further drives the rear roller 42 to achieve passive rolling.

[0045] In some embodiments, the rolling assembly 40 includes a power supply for providing power support to the driving member 43 or other electronic components.

[0046] To facilitate the storage of wiring within the treadmill frame 10, the power supply of the rolling assembly 40 is located within the component installation area 1112 of the frame main beam 111 on one side, while the drive component 43 is located within the component installation area 1112 of the frame main beam 111 on the other side. In other words, the drive component 43 and power supply of the rolling assembly 40 of this embodiment are located within the frame main beam 111 on both sides, which facilitates the layout of wiring.

[0047] like Figure 5As shown, the driving member 43 of this solution is installed in the component installation area 1112 of the frame main beam 111 on one side to drive the front roller 41. In some embodiments, the driving member 43 is a two-stage transmission member, which includes a driving motor 431 and a transmission wheel 433 fixed in the component installation area 1112. The driving motor 431 is connected to the transmission wheel 433 through a primary conveyor belt 432, and the transmission wheel 433 is connected to the front roller 41 through a secondary transmission belt 434, thereby allowing the driving motor 431 to drive the front roller 41 to rotate in a two-stage transmission manner.

[0048] In some embodiments, the front drum 41 is connected to a connecting frame protruding from the frame main beam 111 by bolts.

[0049] like Figure 7 As shown, the rear drum 42 is also connected to the connecting frame protruding from the frame main beam 111 by bolts.

[0050] Example 2 Based on the walking machine provided in the first embodiment, the second embodiment provides a fitness equipment with a treadmill that can provide a height adjustment function. The fitness equipment with a treadmill includes: The treadmill frame 10 includes a main frame 11 and at least one load-bearing reinforcement member 12 mounted on the main frame 11; A rolling assembly 40 , wherein the rolling assembly 40 includes a front roller 41 mounted on the front end of the treadmill frame 10 , a rear roller 42 mounted on the rear end of the treadmill frame 10 , and a driving member 43 for driving the front roller 41 and / or the rear roller 42 ; The running board 20 is mounted on the load-bearing reinforcement 12 and the main frame 11; The treadbelt 30 is mounted on the running deck 20 and wound around the rolling assembly 40; The height adjustment components 60 provided on both sides of the treadmill frame 10 are rotated to adjust the inclination angle of the treadmill frame 10 .

[0051] As mentioned above, the fitness exercise equipment with a treadmill can be either a walking machine or a treadmill.

[0052] like Figure 8 As shown, the height adjustment component 60 provided in this solution includes an adjusting plate 61, a support wheel 62 and a position fixing member 63, wherein the support wheel 62 is connected to the treadmill frame 10 through a rotating shaft, one end of the adjusting member 61 is connected to the support wheel 62 through a rotating shaft, and the other end is connected to the treadmill frame 10 through the position fixing member 63.

[0053] It should be noted that the first end of the adjusting piece 61 is connected to the support wheel 62 through the rotating shaft, and the second end is connected to the treadmill frame 10 through the position fixing piece 63, so that the adjusting piece 61 can rotate relative to the first end to adjust the position of the second end. When the second end of the adjusting piece 62 is adjusted to a specific position, the second end of the adjusting piece 62 and the treadmill frame 10 are fixed through the position fixing piece 63.

[0054] Specifically, at least one rotating shaft is arranged at the side of the treadmill frame 10, the support wheel 62 is sleeved on the rotating shaft and fixed, and the first end of the adjusting piece 61 is also sleeved on the rotating shaft and located between the support wheel 60 and the treadmill frame 10.

[0055] In some embodiments, the fastener 65 passes through the fulcrum end of the adjusting piece 61 to connect the adjusting piece 61 to the treadmill frame 10, wherein the fulcrum end is located between the first end and the second end. At this time, the adjusting piece 61 rotates around the fulcrum end as the rotating fulcrum to adjust the position of the second end. It should be noted that since the first end of the adjusting piece 61 is sleeved on the rotating shaft, when the adjusting piece 61 rotates around the fulcrum end as the rotating fulcrum, the first end of the adjusting piece 61 rotates around the rotating shaft to adjust the position of the second end of the adjusting piece 61.

[0056] Further, the treadmill-based fitness exercise machine additionally comprises a handrail assembly 50, the handrail 52 of the handrail assembly 50 is connected to the treadmill frame 10 and the adjusting piece 61 through the fastener 65, and the handrail 52 is arranged close to the position fixing piece 63, so that the handrail 52 can provide support against the position fixing piece 63. That is, when the movable end of the adjusting piece 61 is turned to a specific matching position, the position fixing piece 63 passes through the second end of the adjusting piece 61 and abuts against the handrail 52 to achieve fixation. At this time, the handrail 50 can provide a counter supporting force for the position fixing piece 63 by virtue of its own connection strength with the treadmill frame 10, avoiding loosening of the position fixing piece 63 when stressed, and improving the stability of the walking machine or running machine at different heights.

[0057] It should be noted that the first load-reinforcing piece 121 is arranged relative to the position of the fastener 65, that is, the fastener 65 is fixed to the first load-reinforcing piece 121 after passing through the treadmill frame 10, so that the first load-reinforcing piece can also strengthen the strength of the height-adjusting assemblies 60 and the handrail assemblies 50 on the left and right sides.

[0058] As Figure 9As shown, a fixing hole 611 is formed on the fulcrum end of the adjusting member 61, and a height adjustment area 612 is formed on the second end of the adjusting member 61, wherein the height adjustment area 612 is composed of a plurality of height adjustment holes. A first opening that cooperates with the fixing hole 611 and a second opening that cooperates with the height adjustment hole are formed on the side of the treadmill frame 10. A connecting hole 51 that cooperates with the fixing hole 611 and the first opening is formed on the handrail 52. A fastener 65 passes through the connecting hole 51, the fixing hole 611 and the first opening to connect the handrail 52 to the treadmill frame 10 and the adjusting plate 61.

[0059] In some embodiments, a plurality of interconnected height adjustment holes are formed on the height adjustment area 612. Each height adjustment hole corresponds to an adjustment gear. This multi-hole design enables the treadmill frame 10 to be adjusted at multiple angles to meet the user's different needs from fast walking on flat ground to climbing training.

[0060] In some embodiments, the height adjustment area 612 is designed to be an arc with the fixing hole 611 as the center, and the height adjustment area 612 is set corresponding to the position of the second opening. When the adjustment member 61 rotates relative to the treadmill frame 10, different height adjustment hole positions on the height adjustment area 612 correspond to the second opening settings. When the treadmill frame 10 rotates, the height adjustment hole positions can accurately correspond to the second openings, ensuring the accuracy and reliability of the angle adjustment. The user can intuitively select different height adjustment hole positions according to needs to obtain the target inclination angle.

[0061] like Figure 10 As shown, when the top height adjustment hole in the height adjustment area 612 corresponds to the second opening setting, the treadmill frame 10 is placed horizontally, and when other height adjustment holes in the height adjustment area 612 correspond to the second opening setting, the treadmill frame 10 is placed horizontally with different degrees of inclination.

[0062] In some embodiments, the position fixing member 63 is designed as a pull pin having a first diameter and a second diameter, wherein the first diameter is larger than the second diameter and the first diameter matches the diameter of the second opening. When the first diameter of the pull pin matches and fits into the second opening, the adjusting plate 61 is locked, and when the second diameter of the pull pin is located in the second opening, the adjusting plate 61 can rotate relative to the second opening.

[0063] When the user needs to increase the training intensity, the treadmill frame can be adjusted to different inclination angles to simulate climbing scenarios, enhancing leg muscle exercise effect; when the user performs relaxation recovery training, the treadmill frame 10 can be adjusted to a horizontal state to reduce joint pressure. When the trainer needs to adjust the inclination angle of the treadmill frame 10, the fastener 65 and the position fixing piece 63 can be unlocked, and then the adjustment piece 61 is rotated to another matching position, and then the fastener 65 is locked and the position fixing piece 63 is inserted into the corresponding height adjustment hole and the second opening, at this time the position fixing piece 63 abuts against the handrail 50 to provide locking force.

[0064] In some embodiments, the fastener 65 adopts a bolt structure. Preferably, the fastener 65 adopts a bolt structure with a bushing.

[0065] In some embodiments, the position fixing piece 63 adopts a quick-release latch structure, cooperates with a spring return design, and the user only needs to press the latch to unlock, and then releases after rotating the adjustment piece to the target angle, and the latch will automatically pop into the corresponding positioning hole to complete the fixing.

[0066] In some embodiments, the bottom end of the fixed support wheel 62 is lower than the bottom end of the treadmill frame 10, which has the advantage that the treadmill frame 10 can be supported by the fixed support wheel 62. This setting can stably support the treadmill frame 10 by the fixed support wheel 62, so that the treadmill frame 10 is not in direct contact with the ground, reducing the wear of the bottom end of the treadmill frame 10 due to friction with the ground, prolonging the service life of the treadmill frame 10. Secondly, since the fixed support wheel 62 itself has a steering function, when the treadmill needs to be moved, the user does not need to lift the treadmill frame, but only needs to push the treadmill, and the fixed support wheel 42 can drive the whole machine to move easily, greatly improving the convenience of movement.

[0067] In some embodiments, the adjustment piece 61 is designed as a bent strip structure, that is, the adjustment piece 61 is integrally formed by the relatively bent first bent part and the second bent part, and preferably, the fixing hole 611 is arranged at the bent connection position of the first bent part and the second bent part, which can provide better structural stability. In some embodiments, the height adjustment assembly 60 additionally includes a support stabilizer 64 disposed between the handrail 50 and the adjustment piece 61, which is arranged to reduce the direct contact between the handrail 50 and the adjustment piece 61 to reduce the wear as much as possible.

[0068] Correspondingly, the support stabilizer 64 is also provided with two holes corresponding to the first opening and the second opening, the first fixing piece passes through the connecting hole 51, the hole of the support stabilizer 64, the fixing hole 611 of the adjustment piece 61 and the first opening in sequence, and the position fixing piece 63 passes through the hole of the support stabilizer 64, the height adjustment hole of the adjustment piece 61 and the second opening in sequence.

[0069] It should be noted that whether it is the embodiment one or the embodiment two, the walking machine can be provided with additional functional parts. For example, in some embodiments, a mobile phone holder can be provided on the handrail 50 to facilitate the trainee to check the electronic device during the walking training; in some embodiments, an electronic remote controller for controlling the movement mode of the walking machine can be provided on the treadmill frame 10 and / or the handrail 50; in some embodiments, a display screen for displaying the movement state of the walking machine can be provided on the treadmill frame 10. The setting of the functional parts can be adjusted according to the actual needs of the walking machine product, which will not be listed here.

[0070] Those skilled in the art should understand that the technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0071] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be noted that for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
