Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment, and in particular to a fully automatic folding treadmill. Background Art

[0002] In today's society, people's pace of life is accelerating, and health issues are receiving more and more attention. With the continuous advancement of urbanization, residents' living space is becoming more compact. At the same time, the public's pursuit of a healthy lifestyle is increasing, which has led to a booming market for home fitness equipment. As a convenient fitness equipment that can perform aerobic exercise indoors, treadmills are deeply loved by fitness enthusiasts and ordinary home users, and their popularity in homes is increasing.

[0003] However, traditional treadmills have exposed many problems in actual use, which seriously affected the user experience and further promotion of the product. First of all, the space occupation problem has become a major concern for many families when choosing a treadmill. The overall structure of a traditional treadmill is relatively fixed, and it still occupies a large indoor space when not in use. For small-sized families with limited living space, this is undoubtedly a defect that cannot be ignored, causing some users to give up buying treadmills due to space constraints.

[0004] Secondly, the complexity of the folding operation is also a major pain point of traditional treadmills. Although some existing folding treadmills have taken the space storage problem into consideration to a certain extent, the folding method is often not designed reasonably, requiring users to manually perform multiple steps, such as frequently plugging and unplugging the fixing pins, adjusting the bracket angle, etc. The whole process is cumbersome and physically demanding. For some users with less strength or inconvenient operation, it is quite difficult to complete the folding operation, which also reduces the user's enthusiasm for using the folding function.

[0005] Furthermore, from the perspective of structural design, existing folding treadmills have obvious deficiencies in their folding structure. During the folding process, due to the inadequate optimization of the connection methods and movement trajectories between the various components, jamming and unsmoothness often occur, which not only affects the folding efficiency, but may also increase the wear between the components and shorten the service life of the treadmill. Moreover, in the folded state, the treadmill still occupies a large space.

[0006] Therefore, there is an urgent need for a newly designed fully automatic folding treadmill to meet users' needs for efficient and convenient fitness. Summary of the invention

[0007] In view of this, the present invention provides a fully automatic folding treadmill, aiming to solve the problems of traditional treadmills having a large footprint, being inconvenient to fold, and having poor stability, and to provide users with more convenient and safe running exercise equipment.

[0008] The present invention provides a fully automatic folding treadmill, comprising a stand, a rear support, and a front support; one end of the rear support is rotatably mounted on the bottom of the stand through a rotating shaft A, and a first electric push rod is mounted on the stand to drive the rotating shaft A and the rear support to rotate and realize automatic folding and unfolding. The other end of the rear support is rotatably connected to the front support, and one end of the rear support and the front support are both provided with a rotating shaft handle and a rotating shaft sleeve, and the rotating shaft handle of the rear support is rotatably connected to the rotating shaft handle of the front support; it also includes a rotating shaft B and an arc folding sheet, the arc folding sheet is arc-shaped and has pin holes at both ends, one end of the arc folding sheet is rotatably connected to the rotating shaft sleeve, and the other end is rotatably connected to the rotating shaft B, and the rotating shaft B is also connected to a second electric push rod. The second electric push rod drives the rotating shaft B to drive the arc folding sheet, thereby changing the position state of the rear support and the front support. In addition, it also includes a running belt, a roller, and a motor that drives the running belt to rotate to meet the normal running exercise needs of users.

[0009] Furthermore, the roller can be slidably mounted on the ends of the rear bracket and the front bracket to fine-tune the tightness of the running belt.

[0010] Furthermore, the rotating shaft handles of the rear bracket and the front bracket are connected by a fixing pin to ensure the stability of the connection. The arc folding sheet and the rotating shaft sleeve are also connected by a fixing pin.

[0011] Furthermore, a connecting plate is provided between the first electric push rod and the rotating shaft A, one end of the connecting plate is tightly clamped on the rotating shaft A, and the other end is rotatably connected to the first electric push rod, so as to realize the effective driving of the rotating shaft A and the rear bracket by the first electric push rod.

[0012] Furthermore, the stand is in the shape of a square frame, and the interior is used to accommodate the folded rear bracket and front bracket, which effectively saves storage space and improves the space utilization of the treadmill.

[0013] Preferably, a control panel is installed on the stand, and the control panel is electrically connected to the first electric push rod, the second electric push rod, and the running belt motor, so that the user can centrally control the folding, unfolding, and running functions of the treadmill through the control panel.

[0014] Furthermore, the curvature radius of the arc folding sheet is adapted to the folding motion trajectory of the rear bracket and the front bracket, thereby ensuring the smoothness and stability of the motion during the folding and unfolding process.

[0015] Furthermore, the first electric push rod and the second electric push rod are linked and coordinated through a control module.

[0016] Optionally, a safety sensor strip is provided at the edge of the running belt. When a human body approaches or touches the safety sensor strip, the running belt motor stops working immediately to ensure the safety of the user during use.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Efficient space utilization: The frame is designed in a square shape, which can accommodate the rear bracket and the front bracket after folding, greatly saving storage space. It is especially suitable for small households.

The ends of the rear bracket 2 and the front bracket 3 are both provided with a support 31, and the support 31 is provided with an adjustment hole 311. The roller 62 is installed on the support 31 through the mounting seat 63 to achieve fine adjustment of the tightness of the running belt 61.

[0036] like Figure 6 , 7 As shown, the rotating shaft handles 23 of the rear bracket 2 and the front bracket 3 are connected by a fixing pin 42 to ensure the stability of the connection. The arc folding piece 41 is also connected to the rotating shaft sleeve 24 by a fixing pin 42.

[0037] like Figure 5 , 8 As shown, a connecting piece 5 is further provided between the first electric push rod 11 and the rotating shaft A 22. One end of the connecting piece 5 is tightly clamped on the rotating shaft A, and the other end is rotatably connected to the first electric push rod 11, so as to realize the effective driving of the rotating shaft A and the rear bracket 2 by the first electric push rod 11.

[0038] like Figure 8 As shown, the stand 1 is in a square shape, and the interior is used to accommodate the folded rear support 2 and front support 3, which effectively saves storage space and improves the space utilization of the treadmill.

[0039] In some embodiments, a control panel is installed on the stand 1. The control panel is electrically connected to the first electric push rod 11, the second electric push rod 21, and the running belt motor 6. It is convenient for the user to centrally control the folding, unfolding and running functions of the treadmill through the control panel.

[0040] The curvature radius of the arc folding sheet 41 is adapted to the folding motion trajectory of the rear bracket 2 and the front bracket 3, ensuring the smoothness and stability of the motion during folding and unfolding. The first electric push rod 11 and the second electric push rod 21 are linked and coordinated through the control module. In some embodiments, a safety sensor strip is also provided on the edge of the running belt 61. When the human body approaches or touches the safety sensor strip, the running belt motor 6 immediately stops working to ensure the safety of the user during use.

[0041] In order to have a more thorough and comprehensive understanding of the disclosure of the present invention, the principle thereof is further explained below in conjunction with the usage method.

[0042] Assembly process: Install the shafts A on both sides of the rear bracket 2 at the bottom of the stand 1, and install the first electric push rod 11 and the connecting piece 5, so that the first electric push rod 11 can effectively drive the rear bracket 2 to rotate. Then, connect the front bracket 3 and the rear bracket 2 through the shaft handle 23 and the fixing pin 42, as shown in FIG. Figure 6 , 7As shown, the arc folding piece 41 is installed on the rotating shaft B4, and then the end of the arc folding piece 41 is connected to the rotating shaft sleeve 24 of the front bracket 3 and the rear bracket 2 through the fixing pin 42. Then the second electric push rod 21 is installed at the bottom of the rear bracket 2, and the piston rod of the second electric push rod 21 is rotatably connected to the middle of the rotating shaft B4. After that, the running belt 61, the roller 62 and the motor 6 are installed, and the position of the roller 62 is adjusted to ensure that the running belt 61 runs smoothly. Finally, the control panel is installed, all electrical circuits are connected, and the wireless communication module can be built in to complete the assembly of the treadmill.

[0043] When in use, the user starts the first electric push rod 11 and the second electric push rod 21 through the control panel or mobile phone or remote control, and the two are linked and coordinated through the control module. The first electric push rod 11 drives the rotating shaft A to rotate the rear bracket 2 out of the inside of the stand 1, and the second electric push rod 21 drives the rotating shaft B 4 to drive the arc folding sheet 41 to move, and then unfold the front bracket 3 to a suitable position to complete the unfolding of the treadmill. The user can set running parameters such as speed, time, etc. on the control panel, start the motor 6 to drive the running belt 61 to rotate, and start running exercise. During the running process, the parameters can be adjusted at any time through the control panel.

[0044] Folding and storage: After running, the user operates the control panel again to start the folding process. Figure 5 , 8 As shown, the first electric push rod 11 and the second electric push rod 21 move in opposite directions, so that the rear bracket 2 and the front bracket 3 are gradually folded, and finally the rear bracket 2 and the front bracket 3 are stored inside the stand 1, completing the folding storage and saving space.

[0045] It should be noted that during running, if the human body approaches or touches the safety sensor strip at the edge of the running belt 61, the safety protection device will be activated immediately, and the running belt motor 6 will stop working to ensure the safety of the user. During exercise, clicking the folding or unfolding button will not control the first electric push rod 11 and the second electric push rod 21. In some embodiments, position sensors, pressure sensors, etc. can also be added. When folding or unfolding is abnormal, such as clamping an object, the operation will be stopped immediately and an alarm will be issued.
