Description
Technical Field
[0001] This utility model relates to a fitness equipment, and more particularly to a smart folding structure for a treadmill screen. Background Technology
[0002] As living standards continue to improve, people are paying more and more attention to physical exercise, and running is the simplest and most effective way to stay fit, making treadmills increasingly popular. For easier storage, some users choose foldable treadmills, which can be folded for storage to save space.
[0003] However, existing folding treadmills typically have a display screen to show running speed, time, distance, and other information. However, this screen is usually fixed to the handrails, meaning it cannot be folded when the treadmill is folded, resulting in significant space occupation. While some screens can be folded by rotating relative to the front frame, existing screens simply rely on a pivot and damping sleeve to rotate on the handrails. Although there is some damping during rotation, the screen's stability is poor due to the significant vibration of the treadmill during use, causing severe shaking and affecting the user experience. Therefore, this application proposes an intelligent folding structure for treadmill screens, which allows for fixed positioning at any angle and ensures structural stability and reliability during use. Utility Model Content
[0004] This utility model provides an intelligent folding structure for treadmill screens, which can achieve fixed positioning at any angle and ensures structural stability and reliability during use. The specific technical solution is as follows:
[0005] A smart folding structure for a treadmill screen includes a screen fixing plate for fixing the screen. The lower side of the screen fixing plate is detachably connected to a rotating shaft. The other end of the rotating shaft is hinged to a rotating shaft seat. The rotating shaft seat is fixed on the front support frame of the treadmill. The rotating shaft seat is provided with a connecting flange. A through hole for the rotating shaft to be inserted is provided at the center of the connecting flange. A disc spring is sleeved on the rotating shaft. A locking nut is screwed to the end of the rotating shaft. The locking nut can cause the disc spring to press against the end of the connecting flange, thereby generating rotational damping between the rotating shaft and the rotating shaft seat. A limit self-locking component is provided on the screen fixing plate. A gear is fixedly sleeved on the outer side of the connecting flange. The limit self-locking component can engage with the gear to achieve a limit when the screen fixing plate is unfolded outward.
[0006] Furthermore, the self-locking limit assembly includes a spring fixing seat and a support rod. The spring fixing seat is fixed on the screen fixing plate. One end of the support rod is provided with a limiting tooth that can mesh with the gear. The other end of the support rod is hinged to the spring fixing seat through a locking screw. A torsion spring is sleeved on the locking screw. One end of the torsion spring is connected to the spring fixing seat, and the other end of the torsion spring is connected to the support rod. The torsion spring can provide a force for the support rod to rotate in the direction closer to the gear.
[0007] Furthermore, the self-locking limiting assembly includes a spring plate, which is sleeved on the connecting flange and located on the side of the gear away from the disc spring. The spring plate can rotate freely relative to the connecting flange. The spring plate is provided with a spring-loaded limiting groove, and the rotating shaft seat is provided with a spring-loaded limiting post. The spring-loaded limiting post is accommodated in the spring-loaded limiting groove to limit the rotation angle of the spring plate. The spring plate is provided with a spring-loaded driving groove. When the screen fixing plate is in the unfolded state, the limiting teeth of the support rod are accommodated in the spring-loaded driving groove. When the screen fixing plate is folded inward, the support rod can abut against the top of the side wall of the spring-loaded driving groove and use the top of the side wall of the spring-loaded driving groove as a fulcrum to overcome the elastic force of the torsion spring and lift the support rod so that the limiting teeth are separated from the gear, thereby realizing the inward folding and rotation of the screen fixing plate.
[0008] Furthermore, multiple disc springs are used to improve the damping effect.
[0009] Furthermore, the rotating shaft is provided with at least one rotating shaft limiting platform, and the disc spring is provided with a connecting hole that matches the cross-sectional shape of the rotating shaft at the location where the rotating shaft limiting platform is located.
[0010] Furthermore, at least one gear limiting platform is provided on the connecting flange, and the gear is provided with a connecting hole that matches the cross-sectional shape of the connecting flange.
[0011] Furthermore, a flat washer is provided between the disc spring and the end of the connecting flange, and a flat washer is also provided between the locking nut and the disc spring.
[0012] Furthermore, a limiting shoulder is provided on the rotating shaft, which can abut against the rotating shaft seat to limit the lateral displacement of the rotating shaft.
[0013] Furthermore, a shaft limiting groove is provided on the limiting shoulder, and a shaft limiting post is provided on the side of the shaft seat that is connected to the limiting shoulder. The shaft limiting post is accommodated in the shaft limiting groove to limit the rotation angle of the shaft.
[0014] Furthermore, the hinge mount and screen support mount are detachably connected to facilitate the replacement and maintenance of the screen and the folding structure as a whole.
[0015] This utility model features an ingenious structural design. It utilizes a self-locking mechanism through the interplay of an elastic support rod and gears, ensuring a secure and reliable lock. The screen can be fixed at any angle. Furthermore, the dual protection of the support rod and gears, along with the damping of the disc spring, significantly enhances the screen's stability during use. Finally, the cooperation between the pivot limiting groove and the pivot limiting post effectively prevents the screen from overtraveling or unfolding, increasing the user's tolerance for error and ensuring a superior user experience.
[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0028] To better understand the purpose, function, and specific design of this utility model, the intelligent folding structure of the treadmill screen of this utility model will be described in further detail below with reference to the accompanying drawings.
[0029] like Figure 1-10 As shown, the intelligent folding structure for a treadmill screen of this utility model includes a screen fixing plate 1 for fixing the screen. The lower side of the screen fixing plate 1 is detachably connected to a rotating shaft 2, and the other end of the rotating shaft 2 is hinged to a rotating shaft seat 3. The screen fixing plate 1 can rotate away from the treadmill, i.e., unfold outward, or rotate towards the treadmill, i.e., fold inward. The rotating shaft seat 3 is fixed on the front support frame of the treadmill. A connecting flange 31 is provided on the rotating shaft seat 3, and a center position of the connecting flange 31 is provided for the rotating shaft. 2. A through hole for insertion is provided. A disc spring 4 is sleeved on the rotating shaft 2. A locking nut 5 is screwed to the end of the rotating shaft 2. The locking nut 5 can make the disc spring 4 press against the end of the connecting flange 31, thereby generating rotational damping between the rotating shaft 2 and the rotating shaft seat 3. Preferably, there are multiple disc springs 4 to improve the damping effect. A limit self-locking component 6 is provided on the screen fixing plate 1. A gear 7 is fixedly sleeved on the outer side of the connecting flange 31. The limit self-locking component 6 can mesh with the gear 7 to achieve limit when the screen fixing plate 1 is unfolded outward.
[0030] Specifically, the self-locking limit assembly 6 includes a spring fixing seat 61 and a support rod 62. The spring fixing seat 61 is fixed on the screen fixing plate 1. One end of the support rod 62 is provided with a limiting tooth 621 that can mesh with the gear 7. The other end of the support rod 62 is hinged to the spring fixing seat 61 by a locking screw 63. A torsion spring 64 is sleeved on the locking screw 63. One end of the torsion spring 64 is connected to the spring fixing seat 61, and the other end of the torsion spring 64 is connected to the support rod 62. The torsion spring 64 can provide a force for the support rod 62 to rotate in the direction of approaching the gear 7.
[0031] The self-locking limit assembly 6 also includes a spring plate 65, which is sleeved on the connecting flange 31 and located on the side of the gear 7 away from the disc spring 4. The spring plate 65 and the connecting flange 31 are in clearance fit, and the spring plate 65 can rotate freely relative to the connecting flange 31. The spring plate 65 is provided with a spring-loaded limiting groove 651, and the rotating shaft seat 3 is provided with a spring-loaded limiting post 32. The spring-loaded limiting post 32 is accommodated in the spring-loaded limiting groove 651 to limit the rotation angle of the spring plate 65. The spring plate 65 is provided with a spring-loaded driving groove 652. As shown in the figure, when the screen fixing plate 1 is in the unfolded state, the limiting tooth 621 of the support rod 62 is accommodated in the spring-loaded driving groove 652 and meshes with the gear 7. At this time, the screen fixing plate 1 cannot rotate outward.
[0032] like Figure 6-7 As shown, when the screen fixing plate 1 is folded inward, the support rod 62 abuts against the top of the side wall of the spring-loaded drive groove 652 and uses the top of the side wall of the spring-loaded drive groove 652 as a fulcrum to overcome the elastic force of the torsion spring 64, thus lifting the support rod 62 to separate the limiting tooth 621 from the gear 7. At this time, the support rod 62 loses its limiting function, thereby realizing the inward folding and rotation of the screen fixing plate 1. When the screen fixing plate 1 is released after rotating to the required angle, the torsion spring 64 drives the support rod 62 to rotate so that the limiting tooth 621 meshes with the gear 7, thereby continuing to limit the movement.
[0033] like Figure 8 As shown, when the screen fixing plate 1 continues to fold and rotate inward, the spring limit groove 651 of the spring piece 65 abuts against the spring limit post 32 and stops rotating. At this time, the screen fixing plate 1 continues to fold and rotate inward, and the limit tooth 621 of the support rod 62 moves to the side of the spring piece 65 until the preset folded storage state is reached.
[0034] When the screen fixing plate 1 unfolds outward from its folded state, the spring piece 65 can rotate freely. Therefore, the spring piece 65 rotates under the drive of the limiting tooth 621 of the support rod 62, such as... Figure 9 As shown, when the other side of the spring-rebound limiting groove 651 of the spring-rebound piece 65 abuts against the spring-rebound limiting post 32, the spring-rebound piece 65 stops rotating. At this time, the screen fixing plate 1 continues to unfold outward, and the limiting tooth 621 of the support rod 62 moves from the side of the spring-rebound piece 65 into the spring-rebound driving groove 652. Then, the limiting tooth 621 of the support rod 62 meshes with the gear 7, as shown. Figure 10 As shown, the maximum unfolding angle is reached at this point.
[0035] Preferably, to facilitate the installation of the rotating shaft 2 and limit its lateral displacement, the rotating shaft 2 in this embodiment is provided with a limiting shoulder 21. The limiting shoulder 21 can abut against the rotating shaft seat 3 to limit the lateral displacement of the rotating shaft 2. It is worth noting that the limiting shoulder 21 in this embodiment is also provided with a rotating shaft limiting groove 22. The rotating shaft seat 3 is provided with a rotating shaft limiting post 33 on the side connected to the limiting shoulder 21. The rotating shaft limiting post 33 is accommodated in the rotating shaft limiting groove 22 to limit the rotation angle of the rotating shaft 2, thereby limiting the maximum and minimum rotation angle of the screen fixing plate 1.
[0036] Preferably, the rotating shaft 2 is provided with at least one rotating shaft limiting platform 23, and in this embodiment, there are two. The disc spring 4 is provided with a connecting hole whose cross-sectional shape matches the position of the rotating shaft 2 where the rotating shaft limiting platform 23 is located, thereby preventing relative rotation between the disc spring 4 and the rotating shaft 2, and thus further improving the damping effect. It is worth noting that a flat washer 8 is provided between the end of the disc spring 4 and the connecting flange 31, and a flat washer 8 is also provided between the locking nut 5 and the disc spring 4, so as to facilitate the disassembly of the disc spring 4 and improve the service life of the disc spring 4.
[0037] In addition, at least one gear limiting platform 34 is provided on the connecting flange 31 in this embodiment, and the gear 7 is provided with a connecting hole that matches the cross-sectional shape of the connecting flange 31, so as to prevent the gear 7 from rotating relative to the connecting flange 31 and to ensure the limiting effect of the support rod 62.
[0038] To facilitate the replacement, repair, packaging, and transportation of the screen and folding structure as a whole, the pivot seat 3 and the screen support seat 9 in this embodiment are detachably connected, and the screen support seat 9 is fixed on the front frame.
[0039] This utility model features an ingenious structural design. It utilizes a self-locking mechanism through the interplay of an elastic support rod and gears, ensuring a secure and reliable lock. The screen can be fixed at any angle. Furthermore, the dual protection of the support rod and gears, along with the damping of the disc spring, significantly enhances the screen's stability during use. Finally, the cooperation between the pivot limiting groove and the pivot limiting post effectively prevents the screen from overtraveling or unfolding, increasing the user's tolerance for error and ensuring a superior user experience.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
