Technical Field

[0001] The present invention belongs to the technical field of treadmills, and specifically relates to a treadmill that is convenient to use. Background Art

[0002] A treadmill is an indoor fitness equipment that simulates the experience of outdoor running. It usually consists of a conveyor belt with adjustable speed and slope, a control panel, handrails, and a support structure. Users can stand on the conveyor belt, set parameters such as running speed, slope, and time through the control panel, and then exercise as if running outdoors. The treadmill provides people with a convenient, controllable, and weather- and environment-independent way of running exercise.

[0003] Currently, existing treadmills do not have a protective device. For some people after intense exercise, it is very easy to have problems with body imbalance on the treadmill, resulting in people falling. The fallen people are prone to hitting their heads, causing harm to the heads of people and also scratching the legs of people. Furthermore, the safety and practicality are reduced.

[0004] Therefore, in view of the above problems, a treadmill that is convenient to use is proposed. Summary of the Invention

[0008] Preferably, the first protection mechanism includes an electric pusher. The electric pusher is rotatably connected inside the rotation notch through a first fixing rod, and the output end of the electric pusher is connected to a push rod. The upper end of the push rod is connected to a connecting member through a second fixing rod. Inside the connecting member, a driving plate is rotatably connected through a third fixing rod. On one side of the driving plate, there is a lifting plate fixedly connected. On one side of the lifting plate, there is a rotation hole, and inside the rotation hole, there is a fourth fixing rod rotatably fitted. The fourth fixing rod is connected to both sides of the upper part inside the support frame.

[0009] Preferably, the lifting plate is provided with first through holes arranged at equal intervals along the length direction. A first sliding rod is slidably fitted inside the first through hole. One end of the first sliding rod is fixedly connected to a first protection plate, and a first sponge member is adhered to the upper surface of the first protection plate. The other end of the first sliding rod is fixedly connected to a first cover plate. One side of the first cover plate is connected to a first spring body, and one end of the first spring body is connected to the lifting plate, and the first spring body is wound around the inside of the sliding rod.

[0010] Preferably, first support components and second support components are arranged on both sides of the lifting plate. The first support component includes a fixed rod and a transmission rod. The transmission rod is rotatably connected to an unfolding plate. One side of the unfolding plate is connected to a sliding block through a fifth fixed rod, and the sliding block is slidably fitted in a sliding notch opened on one side of the support frame. The first support component and the second support component have the same structure.

[0011] Preferably, guide rods are fixedly connected to both sides of the lifting plate.

[0012] Preferably, the second protection mechanism includes a first transmission component and a second transmission component. The first transmission component includes a first transmission plate. A guide groove is opened on one side of the first transmission plate, and the outside of the guide rod is slidably fitted inside the guide groove. One side of the first transmission plate is fixedly connected to a first semi-circular gear, and the first semi-circular gear is connected to one side surface of the machine body through a sixth fixed rod. The first semi-circular gear is engaged with a second semi-circular gear. A seventh fixed rod is sleeved inside the second semi-circular gear, and one side of the outer ring surface of the second semi-circular gear is connected to a second transmission plate. One side of the second transmission plate is fixedly connected to a bearing plate. The first rotation component and the second transmission component have the same structure.

[0013] Preferably, a fixing plate is fixedly connected to the lower end surface of the bearing plate. Second through holes are opened on both sides of the fixing plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] After the lifting plate of the present invention is quickly unfolded, the head of a person who falls down hits the first sponge member, and then with the buffering of the first spring body, the impact force and injury to the person's head can be reduced greatly.

[0017] Through the deployment of the lifting plate, the head of the person can be better protected. The work of the deployable and closable lifting plate avoids occupying the space of the running belt, thereby improving safety and practicality.

[0018] After the bearing plate of the present invention is lifted upward, the part that hits the person's leg will be squeezed in the direction of the second protection plate and the second sponge piece along with the inertia of the fall. By utilizing the buffering of the second spring body and the soft effect of the second sponge piece, the scratches on the leg and the injuries caused by falling outward to the ground can be reduced.

[0019] For people who do not engage in strenuous exercise, through the control of the display screen, the first protection mechanism and the second protection mechanism can be activated, so that the bearing plate moves upward and is fixed at a certain height. Through the height of the bearing plate, people who do not engage in strenuous exercise can sit on the upper end surface of the bearing plate to rest, avoiding the phenomenon of sitting on the ground at will, improving the quality of people in the fitness equipment room, and also ensuring that people can rest in time.

[0020] For people who engage in strenuous exercise, the rotation angle of the lifting plate can be adjusted through the control of the display, and it is adjusted to be comfortable when the person leans on the first protection plate and the first sponge piece, which can quickly restore the person's body and improve comfort.

[0029] Next, in conjunction with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figure 1 shown, the present invention provides a treadmill that is convenient to use, including a body 1. On one side of the upper end surface of the body 1, there is a support frame 11. On both sides of the upper part of the support frame 11, there are a first armrest plate 12 and a second armrest plate 13, and in the middle of the upper end surface of the support frame 11, there is a display 14; in the middle of one side of the body 1, there is a rotation notch 15; inside the support frame 11, there is a first protection mechanism 2; on one side of the body 1, there is a second protection mechanism 3.

[0031] As Figure 2As shown in the figure, the first protection mechanism 2 includes an electric pusher 21, which is rotatably connected inside the rotating notch 15 through a first fixing rod 211. The output end of the electric pusher 21 is connected to a push rod 22. The upper end of the push rod 22 is connected to a connecting member 23 through a second fixing rod 221. Inside the connecting member 23, a driving plate 25 is rotatably connected through a third fixing rod 24. One side of the driving plate 25 is fixedly connected to a lifting plate 26. A rotating hole 261 is provided on one side of the lifting plate 26. Inside the rotating hole 261, a fourth fixing rod 262 is rotatably engaged. The fourth fixing rod 262 is connected to both sides of the upper part inside the support frame 11.

[0032] Adopting the above solution: Start the electric pusher 21 to drive the push rod 22 to move downward. The push rod 22 is pulled to drive the connecting member 23, the third fixing rod 24 and the driving plate 25 to move downward. The driving plate 25 is pulled downward on one side of the lifting plate 26, causing the rotating hole 261 on the lifting plate 26 to rotate upward outside the fourth fixing rod 262. The lifting plate 26 drives the first sliding rod 27, the first protection plate 271 and the first sponge member 272 upward until the lifting plate 26 rotates 45 degrees. Thus, the unfolding work of the lifting plate 26 is completed. As Figure 2 shown, it is beneficial to better protect the head of the personnel. The lifting plate 26 can be unfolded and closed, avoiding occupying the space of the running belt. Thus, the safety and practicality are improved.

[0033] As Figure 3 shown, the lifting plate 26 is provided with first through holes 263 arranged at equal intervals along the length direction. Inside the first through holes 263, first sliding rods 27 are slidably engaged. One end of the first sliding rod 27 is fixedly connected to a first protection plate 271. The upper surface of the first protection plate 271 is adhered with a first sponge member 272. The other end of the first sliding rod 27 is fixedly connected to a first cover plate 273. One side surface of the first cover plate 273 is connected to a first spring body 274. One end of the first spring body 274 is connected to the lifting plate 26, and the first spring body 274 is wound inside the sliding rod 27.

[0034] Adopting the above solution: After the lifting plate 26 is quickly unfolded, the head of the person falling downward hits the first sponge member 272. The first sponge member 272 and the first protection plate 271 are simultaneously subjected to the impact force, causing the first sliding rod 27 and the first cover plate 273 to stretch downward on the first spring body 274. Then, using the buffering of the first spring body 274, the impact force and injury on the head of the person can be reduced significantly.

[0035] The rotation angle of the lifting plate 26 can be adjusted through the control of the display 14. It is comfortable for the adjusting person to lean on the first protection plate 271 and the first sponge member 272, which can quickly restore the person's body and improve the practicality.

[0036] As Figure 4 , Figure 5 shown, first support assemblies 28 and second support assemblies 29 are arranged on both sides of the lifting plate 26. The first support assembly 28 includes a fixed rod transmission rod 281. The transmission rod 281 is rotatably connected to an unfolding plate 282. One side of the unfolding plate 282 is connected to a sliding block 284 through a fifth fixed rod 283. The sliding block 284 is slidably engaged with a sliding notch 285 opened on one side of the support frame 11. The first support assembly 28 and the second support assembly 29 have the same structure.

[0037] Adopting the above solution: during the upward rotation of the lifting plate 26, the transmission rod 281 on the lifting plate 26 drives the unfolding plate 282 to unfold upward. The unfolding plate 282 pulls the sliding block 284 upward under force. The sliding block 284 slides upward inside the sliding notch 25 under force, which is beneficial to stably support the lifting plate 26 through the unfolding of the unfolding plate 282.

[0038] As Figure 4 shown, guide rods 264 are fixedly connected to both sides of the lifting plate 26.

[0039] Adopting the above solution: through the transmission of the guide rods 264, it can ensure that the bearing plate 33 and the lifting plate 26 work simultaneously.

[0040] As Figure 1 , Figure 4 , Figure 6 shown, the second protection mechanism 3 includes a first transmission assembly 31 and a second transmission assembly 32. The first transmission assembly 31 includes a first transmission plate 311. A guide groove 312 is opened on one side of the first transmission plate 311. The inside of the guide groove 312 is slidably engaged with the outside of the guide rod 263. One side of the first transmission plate 311 is fixedly connected to a first semi-circular gear 313. The inside of the first semi-circular gear 313 is connected to one side surface of the machine body 1 through a sixth fixed rod 314. The first semi-circular gear 313 is meshed with a second semi-circular gear 315. A seventh fixed rod 316 is sleeved inside the second semi-circular gear 315. And one side of the outer ring surface of the second semi-circular gear 315 is connected to a second transmission plate 317. One side of the second transmission plate 317 is fixedly connected to a bearing plate 33. The first rotation assembly 31 and the second transmission assembly 32 have the same structure.

[0041] Adopting the above scheme: By the upward lifting of the guide rod 263, the guide rod 262 drives the first transmission plate 311 upward and slides inside the guide groove 312 to one side, so that the first semi-circular gear 313 on the guide rod 262 meshes with the second semi-circular gear 315. Both the first semi-circular gear 313 and the second semi-circular gear 315 rotate outside the sixth fixed rod 314 and the seventh fixed rod 316. After the second semi-circular gear 315 is stressed, it drives the second transmission plate 317 upward. The second transmission plate 317 drives the bearing plate 33 relatively. The bearing plate 33 drives the fixed plate 34, the second sliding rod 36, the second protective plate 37 and the second sponge member 38 to move upward. The first transmission assembly 31 and the second transmission assembly 32 complete the work of lifting the bearing plate 33 upward at the same time. More and more, people without a strong body can sit on the upper end surface of the bearing plate 33 to rest, and there is no need to sit on the ground at will, improving the quality of people in the fitness equipment room and ensuring that people can rest in time.

[0042] As Figure 7 shown, a fixed plate 34 is fixedly connected to the lower end surface of the bearing plate 33. Second through holes 35 are formed on both sides of the fixed plate 34. A second sliding rod 36 is slidably fitted inside the second through holes 35. One end of the second sliding rod 36 is connected to a second cover plate 361. A second spring body 362 is fixedly connected to one side surface of the second cover plate 361. One end of the second spring body 362 is fixedly connected to the fixed plate 34. The other end of the second sliding rod 36 is fixedly connected to a second protective plate 37. A second sponge member 38 is adhered to one side surface of the second protective plate 37.

[0043] Adopting the above scheme: After the bearing plate 33 is lifted upward, the leg of the person falling on it will be squeezed in the direction of the second protective plate 37 and the second sponge member 38 along with the inertia of the fall, so that the second sliding rod 36 and the second cover plate 361 are stretched to one side with respect to the second spring body 362. By the buffering of the second spring body 362 and the softening effect of the second sponge member 38, the scratches on the leg and the injuries caused by falling to the ground can be reduced.

[0044] As Figure 1 shown, a first infrared emitter 121 is provided on one side surface of the first armrest plate 12, and a second infrared sensor 141 is provided at the middle upper part of one side surface of the display 14.

[0045] Adopting the above scheme: Through the setting of the first infrared sensor 131 and the second infrared sensor 141, the human body can be accurately detected, ensuring the accurate opening of the protection work of the first protection mechanism 2 and the second protection device 3.

[0046] The working principle and usage process of the present invention:

[0047] First, when a person stands on the running belt of the body 1, with the person's face facing the second infrared sensor 141 and the upper side of the person facing the first infrared sensor 131. After the second infrared sensor 141 and the first infrared sensor 131 sense the person, the display screen 14 can start the cyclic movement of the running belt. After the person exercises vigorously, if there is body incoordination, the upper half of the person's body will tilt downward. At this time, the second infrared sensor 141 cannot sense the person due to the tilt of the person, and the first infrared sensor 131 cannot sense the person due to the tilt of the person. At this time, the signals received by the first infrared sensor 131 and the second infrared sensor 141 are transmitted to the controller in the display screen 14. After receiving the signal, the controller starts the electric pusher 21 to drive the push rod 22 to move downward. The push rod 22 pulls the connecting piece 23, the third fixing rod 24, and the driving plate 25 downward under force. The driving plate 25 pulls one side of the lifting plate 26 downward under force, causing the rotating hole 261 on the lifting plate 26 to rotate upward outside the fourth fixing rod 262. The lifting plate 26 drives the first sliding rod 27, the first protective plate 271, and the first sponge member 272 upward until the lifting plate 26 rotates 45 degrees, thus completing the unfolding work of the lifting plate 26, as Figure 2 shown. At the same time, during the upward rotation of the lifting plate 26, the transmission rod 281 on the lifting plate 26 drives the unfolding plate 282 to unfold upward. The unfolding plate 282 pulls the sliding block 284 upward under force. The sliding block 284 slides upward inside the sliding slot 25, and the work of unfolding the first support assembly 28 and the second support assembly 29 is completed, as Figure 4 shown. At this time, the work of the running belt will also stop. After quickly unfolding the lifting plate 26, the head of the person falling downward hits the first sponge member 272. The first sponge member 272 and the first protective plate 271 are simultaneously subjected to the impact force, causing the first sliding rod 27 and the first cover plate 273 to stretch downward the first spring body 274. Then, by using the buffering of the first spring body 274 and the softness of the first sponge member 272, the impact force on the person's head is effectively reduced.

[0048] Among them, during the upward rotation of the lifting plate 26, the upward lifting of the guide rod 263 is utilized to drive the guide rod 262 upward to drive the first transmission plate 311, and slide it upward inside the guide groove 312 to engage the first semi-circular gear 313 on the guide rod 262 with the second semi-circular gear 315. Both the first semi-circular gear 313 and the second semi-circular gear 315 rotate outside the sixth fixed rod 314 and the seventh fixed rod 316. After the second semi-circular gear 315 is stressed, it drives the second transmission plate 317 upward. The second transmission plate 317 drives the bearing plate 33 relatively. The bearing plate 33 drives the fixed plate 34, the second sliding rod 36, the second protective plate 37, and the second sponge member 38 to move upward. Its first transmission assembly 31 and second transmission assembly 32 simultaneously complete the work of lifting the bearing plate 33 upward. The height of the upward lift of the bearing plate 33 is related to the angle of the upward rotation of the lifting plate 26. After the bearing plate 33 is lifted upward, the part hitting the person's leg will be squeezed in the direction of the second protective plate 37 and the second sponge member 38 along with the inertia of the fall, stretching the second sliding rod 36 and the second cover plate 361 to one side of the second spring body 362. By using the buffering of the second spring body 362 and the soft effect of the second sponge member 38, the injury to the person's leg can be reduced.

[0049] For those who do not have intense exercise, through the control of the display screen 14, the first protection mechanism 2 and the second protection mechanism 3 can be started to move the bearing plate 33 upward and fix it at a certain height. Through the height of the bearing plate 33, those without intense exercise can sit on the upper end surface of the bearing plate 33 to rest.

[0050] For those who have intense exercise, the angle of rotation of the lifting plate 26 can be adjusted through the control of the display 14. It is comfortable for the adjusted person to lean on the first protection plate 271 and the first sponge member 272, and the person's body can be quickly restored.

[0051] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
