Description

Technical Field

[0001] The invention relates to the technical field of treadmills, in particular to an anti-fall treadmill with a buffering and shock-absorbing structure. Background Art

[0002] As we all know, treadmills are common fitness equipment in homes and gyms. They are the simplest type of home fitness equipment today and the best choice for home fitness equipment. Treadmills are also equipped with intelligent monitoring and control functions, which can prevent falls.

[0003] In order to reduce the impact on the human body and increase the comfort of running when using the treadmill, treadmills are generally designed with running board buffer devices. Some treadmills use soft running boards for shock absorption. The running boards are relatively thin and absorb the kinetic energy generated by the user's exercise through the deformation of the running boards to achieve a buffering effect. This buffering method cannot well disperse the impact force of the treadmill running board on the knee joint, and there is a soft feeling when stepping on the running board. The foot is not firm, which can easily cause the body to sway left and right, and the safety will be poor. If the treadmill running board is in a bent state for a long time, it is easy to cause the running board to deform and the service life is short.

[0004] After searching, a Chinese patent disclosed a multi-level buffer structure for a fitness treadmill plate. Its application publication number is CN107441675B. The patent has multi-level buffering, multi-directional buffering and shock absorption in the horizontal and vertical directions, and layer-by-layer buffering, which reduces the treadmill's rebound impact force on the human body and relieves the pressure on the knee joints and lumbar spine.

[0005] In view of the above problems, existing patents have provided solutions. However, since treadmills have a wide audience, there are individual differences in the cushioning and shock absorption of treadmills due to the weight and running habits of users. However, the existing technology cannot adapt to the needs of users with different weights and running habits, which makes the cushioning and shock absorption of treadmills in the existing technology have certain limitations in use. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the present invention provides a fall-resistant treadmill with a buffering and shock-absorbing structure, which has an adjustable buffering and shock-absorbing structure function, allowing users to adjust the running experience according to their own characteristics. For example, people with heavier weight can increase the shock absorption strength to reduce joint pressure, and people with lighter weight can appropriately reduce the shock absorption hardness to obtain clearer ground feedback, thereby achieving the advantages of personalized and comfortable running experience, meeting the differentiated characteristics of different users' weight, running posture and exercise needs, and allowing users to make optimization adjustments according to specific exercise modes.

[0008] (II) Technical solution

[0009] The above technical objectives of the present invention are achieved through the following technical solutions: a fall-proof treadmill with a buffering and shock-absorbing structure, comprising a treadmill body, a support arm and a buffering and shock-absorbing assembly, the treadmill body comprising two treadmills, a running belt is arranged between the two treadmills on opposite sides, support arms are bolted to the rear sides of the two treadmills on opposite sides, and handrails are bolted to the tops of the support arms, a controller is bolted between the two handrails on opposite sides, the support arms are located on both sides of the bottom of the treadmill, and the buffering and shock-absorbing assembly is bolted to the front and rear sides between the two support arms on opposite sides, and the top of the buffering and shock-absorbing assembly is bolted to the treadmill;

[0010] The buffer shock absorbing assembly includes an upper connecting plate and a lower supporting plate, the upper connecting plate is bolted to the treadmill, and the side of the lower supporting plate close to the supporting arm is bolted to the supporting arm, a plurality of supporting foot pads are arranged at the bottom of the lower supporting plate, and both sides between the upper connecting plate and the lower supporting plate on opposite sides are bolted with adjusting energy dissipation structures, and a limiting structure is arranged between the upper connecting plate and the lower supporting plate on opposite sides.

[0011] By adopting the above technical solution, a buffer shock-absorbing component is set, and the upper connecting plate and the lower supporting plate are respectively in contact with the treadmill and the ground, so as to play the effect of supporting the treadmill body. By adjusting the energy dissipation structure, the buffer shock-absorbing component can be made adjustable, so that the vibration generated during the movement of the treadmill body can be flexibly buffered and dissipated, thereby allowing users to adjust the running experience according to their own characteristics, such as people with heavier weight can increase the shock absorption strength to reduce joint pressure, and people with lighter weight can appropriately reduce the shock absorption hardness to obtain clearer ground feedback, thereby achieving the advantages of personalized comfortable running experience, meeting the differentiated characteristics of different users' weight, running posture and exercise needs, and allowing users to optimize and adjust according to specific exercise modes. At the same time, for people with old injuries to the knees or ankles, the setting of the buffer shock-absorbing component can greatly reduce the pressure of exercise on the injured part and avoid aggravation of the injury. Under the setting of the limiting structure, the displacement caused by vibration can be reduced, thereby meeting the needs of different users, so that the treadmill body has good flexibility.

[0012] The present invention is further configured as follows: the adjustable energy dissipation structure includes a connecting seat, the connecting seat is bolted to the bottom of the upper connecting plate, an adjusting piece is provided at the bottom of the connecting seat, and an energy dissipation piece is provided inside the adjusting piece, the bottom of the energy dissipation piece extends to the bottom of the adjusting piece, and the top of the energy dissipation piece passes through the adjusting piece and is bolted to the connecting seat, and the bottom of the energy dissipation piece is bolted to the lower support plate through a pin shaft.

[0013] By adopting the above technical solution, an adjustable energy dissipation structure is set up, which can be easily connected to the upper connecting plate through a connecting seat. Under the action of the adjusting part, the shock-absorbing softness and hardness of the treadmill body can be easily adjusted. Therefore, whether it is for home use, professional training in the gym or rehabilitation purposes, the adjustable energy dissipation structure can meet the diverse needs of different scenes and people. At the same time, the energy dissipation part can be used to buffer and dissipate the force generated during the movement of the treadmill body, reduce the wear of the treadmill body caused by the vibration force, and reduce the rebound impact force of the treadmill body on the human body, thereby alleviating the pressure on the knee joints and lumbar vertebrae.

[0014] The present invention is further configured as follows: the adjusting member includes a supporting shell, the supporting shell is sleeved on the top of the surface of the energy dissipating member, and a protective shell is welded on the surface of the supporting shell, a sac body is provided on the top of the surface of the supporting shell, and the top of the sac body is connected to the connecting seat, an air inlet and an exhaust duct are respectively opened on both sides of the interior of the supporting shell, and the air inlet and the exhaust duct are both connected to the sac body, and the bottoms of the air inlet and the exhaust duct are both connected to a valve body structure.

[0015] By adopting the above technical solution, by setting an adjustment part, the valve body structure can be connected to an external high-pressure gas generating device through the air inlet and the exhaust duct. The high-pressure gas is injected into the bladder through the air inlet to increase the air pressure in the bladder. Due to the increase in air pressure, the supporting force of the bladder is enhanced, thereby making the buffer shock-absorbing component harder. On the contrary, part of the air in the bladder is discharged through the exhaust duct to reduce the pressure in the bladder. Due to the reduction in pressure, the supporting force of the bladder is weakened, and the support of the buffer shock-absorbing component to the treadmill body will also become softer, thereby allowing users to increase the shock absorption strength according to their own characteristics. For example, people with heavier weight can increase the shock absorption strength to reduce joint pressure, while people with lighter weight can appropriately reduce the shock absorption hardness to obtain clearer ground feedback, thereby achieving the advantages of personalized comfortable running experience and meeting the differentiated characteristics of different users' weight, running posture and exercise needs.

[0016] The present invention is further configured as follows: a connecting protrusion is provided on the top of the support shell surface, and a groove is provided on the top of the connecting protrusion; the bottom end of the capsule is U-shaped and extends to the inside of the groove and is connected thereto.

[0017] By adopting the above technical solution and providing the connecting protrusions and the grooves, the capsule body can be connected to the supporting shell.

[0018] The present invention is further configured as follows: the energy dissipation component includes a fixed cylinder, the bottom of the fixed cylinder is bolted to the lower support plate through a pin structure, an annular partition is welded inside the fixed cylinder, and a liquid storage chamber and a flow chamber are formed between the annular partition and the inner wall of the fixed cylinder, a piston component is slidably connected inside the liquid storage chamber, and a piston rod is bolted to the top of the piston component, the top of the piston rod passes through the adjusting component and is bolted to the connecting seat, an energy dissipation spring is bolted to the bottom of the piston component, and the bottom of the energy dissipation spring is connected to the inner wall of the fixed cylinder, and a plurality of cavities are opened at the top and bottom of the annular partition.

[0019] By adopting the above technical solution, by setting the energy dissipation part, when the upper connecting plate is subjected to force, the force will be transmitted to the piston rod through the connecting seat, so that the piston rod pushes the piston part to move in the liquid storage chamber and the energy dissipation spring will contract. The movement of the piston part will squeeze the oil, so that the oil gradually passes through the hole cavity into the flow cavity formed between the annular partition and the fixed cylinder. During the oil extrusion process, the oil is easily squeezed out due to the large annular gap between the piston part and the piston part. When the piston part continues to move, the annular gap becomes smaller and smaller, that is, the resistance of the piston part continues to increase. After the final stage of oil extrusion, the annular gap is zero, and the resistance is also stable at the maximum value. In addition, the oil will consume the kinetic energy of the force during the extrusion process, thereby achieving the effect of buffering and dissipating the force. Therefore, the wear of the treadmill body caused by the vibration force and the counter-impact force of the treadmill body on the human body can be reduced, and the pressure on the knee joint and lumbar vertebrae can be relieved.

[0020] The present invention is further configured as follows: the piston member includes a piston body, the piston body is slidably connected to the inside of the liquid storage chamber, and two sealing rings are sleeved on the surface of the piston body, the surface of the sealing ring is in sliding contact with the inner wall of the annular partition, a ring-shaped check hole is opened inside the piston body, and a check ball is arranged inside the check hole, a check spring is arranged at the bottom of the check ball, and the bottom of the check spring is in contact with the inner wall of the check hole.

[0021] By adopting the above technical solution and setting a piston part, when the piston rod loses the force, the energy dissipation spring can push the piston body and the piston rod to reset under its own elastic force, so that the upper end space of the inner tube is compressed. Therefore, the pressure of the oil will overcome the elastic force of the check spring, so that the check ball releases the blockage of the check hole. Therefore, the oil will enter the lower end space of the liquid storage chamber through the check hole, which is convenient for the next buffering and energy dissipation work.

[0022] The present invention is further configured such that: both sides of the upper connecting plate are bolted with connecting shells, and the front and rear sides inside the connecting shell are rotatably connected to limiting wheels, a limiting groove is provided on one side of the support arm close to the connecting shell, and the limiting wheel is in rolling contact with the inner wall of the limiting groove on one side.

[0023] By adopting the above technical solution, by setting a connecting shell, a limiting wheel and a limiting groove, when the upper connecting plate is moved under force, the connecting shell and the limiting wheel will be synchronously driven to move inside the limiting groove, thereby achieving the effect of limiting the moving trajectory of the upper connecting plate.

[0024] The present invention is further configured as follows: the limiting structure includes two upper support blocks and two lower support blocks, the upper support block and the lower support block are respectively bolted to one side of the upper connecting plate and the lower supporting plate near the two sides of the upper connecting plate, and the two lower support blocks are welded with support rods on the opposite sides of the two lower support blocks, and the surfaces of the support rods are slidably connected with guide pillars, a fixed shell is sleeved between the surfaces of the two guide pillars, the opposite sides of the two guide pillars are bolted with fixed seats, and a movable seat is provided on the side of the fixed seat away from the guide pillar, a main limit spring is bolted between the opposite sides of the two movable seats, a guide rod is provided inside the fixed seat, the side of the guide rod close to the movable seat extends to the inside of it, and the surface of the guide rod is sleeved with a secondary limit spring, the side of the secondary limit spring close to the fixed seat and the movable seat is respectively connected to the two, the upper support block is rotatably connected with a connecting rod, and the side of the connecting rod close to the guide pillar is rotatably connected to the guide pillar.

[0025] By adopting the above technical solution and setting a limit structure, when the upper connecting plate is moved under force, the connecting rod connected to the upper support block will push the guide column to move on the surface of the support rod, and move the guide column and the fixed seat, and squeeze the auxiliary limit spring. Under the action of the auxiliary limit spring, small impact forces can be buffered, and under the action of large impact forces, the guide column will push the movable seat to move, thereby contracting the main limit spring. Therefore, large impact forces can be buffered by the main limit spring, thereby satisfying the buffering and shock absorption effects of forces of different sizes.

[0026] The present invention is further configured as follows: the treadbelt comprises a surface running board layer, an elastic layer and a shock absorbing layer are respectively arranged inside the surface running board layer, and the shock absorbing layer is arranged between opposite sides of two elastic layers.

[0027] By adopting the above technical solution, the treadmill is composed of a surface running board layer, an elastic layer and a shock-absorbing layer. Under the action of the elastic layer and the shock-absorbing layer, the contact part between the surface running board layer and the user can have a slight buffering and shock-absorbing effect, avoiding rigid impact between the two, and making the two have a flexible contact effect, which effectively protects the user. For people with old injuries to the knees or ankles, it can greatly reduce the pressure of exercise on the injured part and avoid worsening of the injury.

[0028] The present invention is further configured as follows: the surface running board layer is made of PVC rubber, and the surface is provided with anti-skid patterns, and the elastic layer and the shock-absorbing layer are respectively made of silica gel and shock-absorbing space cotton.

[0029] By adopting the above technical solution, by arranging the surface running board layer, the pop-up layer and the shock-absorbing layer to be composed of PVC rubber, silicone and shock-absorbing space cotton respectively, the contact part between the running belt and the user can have a slight buffering and shock-absorbing effect, avoiding rigid impact between the two, and making the two have a flexible contact effect, effectively protecting the user.

[0030] (III) Beneficial effects

[0031] Compared with the prior art, the present invention provides a fall-proof treadmill with a buffering and shock-absorbing structure, which has the following beneficial effects:

[0032] The anti-fall treadmill with a buffering and shock-absorbing structure can support the treadmill body by setting a buffering and shock-absorbing component, which contacts the treadmill and the ground respectively through an upper connecting plate and a lower supporting plate, and can play a role in supporting the treadmill body. By adjusting the energy dissipation structure, the buffering and shock-absorbing component can be made adjustable, so that the vibration generated during the movement of the treadmill body can be flexibly buffered and energy dissipated, thereby allowing users to increase the shock absorption strength according to their own characteristics, such as people with heavier weight can increase the shock absorption strength to reduce joint pressure, and people with lighter weight can appropriately reduce the shock absorption hardness to obtain clearer ground feedback, thereby achieving the advantages of personalized comfortable running experience, meeting the differentiated characteristics of different users' weights, running postures and exercise needs, and allowing users to optimize and adjust according to specific exercise modes.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-10A fall-proof treadmill with a buffering and shock-absorbing structure comprises a treadmill body 1, a support arm 2 and a buffering and shock-absorbing assembly 3. The treadmill body 1 comprises two treadmills 11, a running belt 12 is arranged between opposite sides of the two treadmills 11, support arms 13 are bolted to the rear sides of opposite sides of the two treadmills 11, and handrails 14 are bolted to the tops of the support arms 13, a controller 15 is bolted between opposite sides of the two handrails 14, the support arms 2 are located at both sides of the bottom of the treadmill 11, and the buffering and shock-absorbing assembly 3 is bolted to the front and rear sides between opposite sides of the two support arms 2, and the top of the buffering and shock-absorbing assembly 3 is bolted to the treadmill 11;

[0046] The buffer shock absorbing assembly 3 includes an upper connecting plate 31 and a lower supporting plate 32, the upper connecting plate 31 is bolted to the treadmill 11, and the side of the lower supporting plate 32 close to the supporting arm 2 is bolted to the supporting arm 2, a plurality of supporting foot pads 33 are arranged at the bottom of the lower supporting plate 32, and an adjustable energy dissipation structure 34 is bolted to both sides between the upper connecting plate 31 and the lower supporting plate 32 on opposite sides, and a limiting structure 35 is arranged between the upper connecting plate 31 and the lower supporting plate 32 on opposite sides. By arranging the buffer shock absorbing assembly 3, the upper connecting plate 31 and the lower supporting plate 32 are in contact with the treadmill 11 and the ground respectively, so as to play the effect of supporting the treadmill body 1, and by adjusting the energy dissipation structure 34, the buffer shock absorbing assembly 3 can be made adjustable, so as to adjust the energy dissipation structure 34. Vibration is flexibly buffered and energy dissipated, allowing users to adjust their running experience according to their own characteristics. For example, people with heavier weight can increase the shock absorption strength to reduce joint pressure, and people with lighter weight can appropriately reduce the shock absorption hardness to obtain clearer ground feedback, thereby achieving personalized and comfortable running experience advantages, meeting the differentiated characteristics of different users' weight, running posture and exercise needs, and allowing users to optimize and adjust according to specific exercise modes. At the same time, for people with old injuries to the knees or ankles, the setting of the buffering and shock absorbing component 3 can greatly reduce the pressure of exercise on the injured part and avoid aggravating the injury. Under the setting of the limiting structure 35, it can reduce the displacement caused by vibration, thereby meeting the needs of different users and making the treadmill body 1 have good flexibility in use.

[0047] The energy dissipation structure 34 includes a connecting seat 341, which is bolted to the bottom of the upper connecting plate 31. An adjusting member 342 is provided at the bottom of the connecting seat 341, and an energy dissipation member 343 is provided inside the adjusting member 342. The bottom of the energy dissipation member 343 extends to the bottom of the adjusting member 342, and the top of the energy dissipation member 343 passes through the adjusting member 342 and is bolted to the connecting seat 341. The bottom of the energy dissipation member 343 is bolted to the lower support plate 32 through a pin shaft. By setting the energy dissipation structure 34, the upper connecting plate 31 can be easily connected to the connecting seat 341. The connecting plate 31 is connected, and under the action of the adjusting member 342, the shock-absorbing softness and hardness of the treadmill body 1 can be easily adjusted. Therefore, whether it is for home use, professional training in the gym or rehabilitation purposes, the adjustable energy dissipation structure 34 can meet the diverse needs of different scenes and people. At the same time, the energy dissipation member 343 can be used to buffer and dissipate the force generated during the movement of the treadmill body 1, reduce the wear of the treadmill body 1 caused by the vibration force, and reduce the rebound impact force of the treadmill body 1 on the human body, thereby relieving the pressure on the knee joints and lumbar vertebrae.

[0048] The regulating member 342 comprises a supporting shell 3421, the supporting shell 3421 is sleeved on the top of the surface of the energy dissipating member 343, and a protective shell 3422 is welded on the surface of the supporting shell 3421, a capsule 3423 is arranged on the top of the surface of the supporting shell 3421, and the top of the capsule 3423 is connected to the connecting seat 341, an air inlet 3424 and an exhaust 3425 are respectively provided on both sides of the interior of the supporting shell 3421, and the air inlet 3424 and the exhaust 3425 are both connected to the capsule 3423, and the bottoms of the air inlet 3424 and the exhaust 3425 are both connected to a valve body structure, and by setting the regulating member 342, the air inlet 3424 and the exhaust 3425 can be connected to an external high-pressure gas generating device through the valve body structure, and the high-pressure gas passes through the air inlet 342 4 is injected into the capsule 3423 to increase the air pressure in the capsule 3423. Due to the increase in air pressure, the supporting force of the capsule 3423 is enhanced, thereby making the buffer shock absorbing component 3 harder. On the contrary, part of the air in the capsule 3423 is discharged through the exhaust duct 3425 to reduce the pressure in the capsule 3423. Due to the reduction in pressure, the supporting force of the capsule 3423 is weakened, and the support of the buffer shock absorbing component 3 on the treadmill body 1 will also become softer, thereby allowing the user to increase the shock absorption strength according to their own characteristics, such as a heavier person can increase the shock absorption strength to reduce joint pressure, and a lighter person can appropriately reduce the shock absorption hardness to obtain clearer ground feedback, thereby achieving the advantages of personalized comfortable running experience and meeting the differentiated characteristics of different users' weights, running postures and exercise needs.

[0049] Among them, a connecting protrusion is set on the top of the surface of the supporting shell 3421, and a groove is set on the top of the connecting protrusion. The bottom end of the capsule 3423 is set in a U shape and extends to the inside of the groove and is connected thereto. By setting the connecting protrusion and the groove, the capsule 3423 can be connected to the supporting shell 3421.

[0050] The energy dissipation member (343) includes a fixed cylinder 3431, the bottom of the fixed cylinder 3431 is bolted to the lower support plate 32 through a pin structure, an annular baffle 3432 is welded inside the fixed cylinder 3431, and a liquid storage chamber 3433 and a flow chamber 3434 are formed between the annular baffle 3432 and the inner wall of the fixed cylinder 3431, a piston member 3435 is slidably connected inside the liquid storage chamber 3433, and a piston rod 3436 is bolted to the top of the piston member 3435 The top of the piston rod 3436 passes through the adjusting member 342 and is bolted to the connecting seat 341. The bottom of the piston member 3435 is bolted with an energy dissipation spring 3437, and the bottom of the energy dissipation spring 3437 is connected to the inner wall of the fixed cylinder 3431. The top and bottom of the annular partition 3432 are provided with a plurality of cavities 3438. By setting the energy dissipation member 343, when the upper connecting plate 31 is subjected to force, the force will be transmitted to the piston rod 3436 through the connecting seat 341. , so that the piston rod 3436 pushes the piston member 3435 to move in the liquid storage chamber 3433 and contracts the energy dissipation spring 3437. The movement of the piston member 3435 will squeeze the oil, so that the oil gradually passes through the hole cavity 3438 into the flow chamber 3434 formed between the annular partition 3432 and the fixed cylinder 3431. During the oil squeezing process, the oil is easily squeezed out due to the large annular gap between the piston member 3435. When the piston member 3435 continues to move, the annular gap becomes smaller and smaller, that is, the resistance of the piston member 3435 continues to increase. After the final stage of oil squeezing, the annular gap is zero. At this time, the resistance is also stable at the maximum value, and the oil will consume the kinetic energy of the force during the squeezing process, thereby achieving the effect of buffering and dissipating the force. Therefore, the wear of the treadmill body 1 caused by the vibration force and the counter-impact force of the treadmill body 1 on the human body can be reduced, thereby relieving the pressure on the knee joint and lumbar vertebrae.

[0051] The piston member 3435 includes a piston body 34351, which is slidably connected to the inside of the liquid storage chamber 3433, and two sealing rings 34352 are sleeved on the surface of the piston body 34351, and the surface of the sealing ring 34352 is in sliding contact with the inner wall of the annular partition 3432, and a ring-shaped check hole 34353 is opened inside the piston body 34351, and a check ball 34354 is arranged inside the check hole 34353, and a check spring 34355 is arranged at the bottom of the check ball 34354, and the check spring 34355 is arranged at the bottom of the check ball 34354. The bottom is in contact with the inner wall of the check hole 34353. By setting the piston part 3435, when the piston rod 3436 loses its force, the energy dissipation spring 3437 can push the piston body 34351 and the piston rod 3436 to reset under its own elastic force, so that the upper end space of the inner cylinder is compressed. Therefore, the pressure of the oil will overcome the elastic force of the check spring 34355, so that the check ball 34354 releases the blockage of the check hole 34353. Therefore, the oil will enter the lower end space of the liquid storage chamber 3433 through the check hole 34353, so as to facilitate the next buffering and energy dissipation work.

[0052] Among them, the two sides of the upper connecting plate 31 are bolted with a connecting shell 4, and the front and rear sides inside the connecting shell 4 are rotatably connected to the limiting wheels 5. A limiting groove 6 is provided on the side of the support arm 2 close to the connecting shell 4, and the side of the limiting wheel 5 close to the inner wall of the limiting groove 6 is in rolling contact with it. By setting the connecting shell 4, the limiting wheel 5 and the limiting groove 6, when the upper connecting plate 31 is moved under force, the connecting shell 4 and the limiting wheel 5 will be synchronously driven to move inside the limiting groove 6, thereby achieving the effect of limiting the moving trajectory of the upper connecting plate 31.

[0053] The limiting structure 35 includes two upper supporting blocks 351 and two lower supporting blocks 352. The upper supporting blocks 351 and the lower supporting blocks 352 are respectively bolted to the upper connecting plate 31 and the lower supporting plate 32 on one side thereof. Support rods 353 are welded to the opposite sides of the two lower supporting blocks 352. The surfaces of the support rods 353 are slidably connected with guide pillars 354. A fixed shell 355 is sleeved between the surfaces of the two guide pillars 354. A fixed seat 356 is bolted to the opposite sides of the two guide pillars 354. A movable seat 357 is provided on the side of the fixed seat 356 away from the guide pillar 354. A main limiting spring 358 is bolted between the opposite sides of the two movable seats 357. A guide rod 359 is provided inside the fixed seat 356. The guide rod 359 extends to the inside of the movable seat 357 on the side thereof close to the movable seat 357. An auxiliary limiting spring 3510 is sleeved on the surface of the guide rod 359. The spring 3510 is connected to the fixed seat 356 and the movable seat 357 on one side thereof, and the upper support block 351 is rotatably connected to the connecting rod 3511 inside, and the connecting rod 3511 is rotatably connected to the guide column 354 on one side thereof, and the limiting structure 35 is provided, when the upper connecting plate 31 is subjected to force and moves, the connecting rod 3511 connected to the upper support block 351 will push the guide column 354 to move on the surface of the support rod 353, and move the guide column 354 and the fixed seat 356, and squeeze the auxiliary limiting spring 3510, under the action of the auxiliary limiting spring 3510, small impact forces can be buffered, and under the action of large impact forces, the guide column 354 will push the movable seat 357 to move, thereby contracting the main limiting spring 358, and thus the large impact forces can be buffered by the main limiting spring 358, thereby satisfying the buffering and shock-absorbing effects of forces of different magnitudes.

[0054] The treadmill 12 comprises a surface running board layer 121, and an elastic layer 122 and a shock absorbing layer 123 are respectively arranged inside the surface running board layer 121, and the shock absorbing layer 123 is arranged between the opposite sides of the two elastic layers 122. By arranging the treadmill 12 to be composed of the surface running board layer 121, the elastic layer 122 and the shock absorbing layer 123, under the action of the elastic layer 122 and the shock absorbing layer 123, the contact part between the surface running board layer 121 and the user can have a slight buffering and shock absorbing effect, avoiding rigid impact between the two, and making the two have a flexible contact effect, which effectively protects the user. For people with old injuries to the knees or ankles, it can greatly reduce the pressure of exercise on the injured part and avoid aggravation of the injury.

[0055] Among them, the surface running board layer 121 is made of PVC rubber and has anti-slip texture on the surface. The elastic layer 122 and the shock-absorbing layer 123 are respectively made of silicone and shock-absorbing space cotton. By arranging the surface running board layer 121, the pop-up layer and the shock-absorbing layer 123 to be respectively made of PVC rubber, silicone and shock-absorbing space cotton, the contact part between the running belt 12 and the user can have a slight buffering and shock-absorbing effect, avoiding rigid impact between the two, and making the two have a flexible contact effect, which effectively protects the user.

[0056] Working principle of this embodiment: firstly, the hardness of the buffer shock absorbing component 3 is adjusted according to the use requirements. The air generating device can be connected to the external part through the adjusting part 342, and the high-pressure gas is injected into the capsule 3423 through the air inlet 3424 to increase the air pressure in the capsule 3423. As the air pressure increases, the supporting force of the capsule 3423 is enhanced, thereby making the buffer shock absorbing component 3 harder. On the contrary, part of the air in the capsule 3423 is discharged through the exhaust duct 3425 to reduce the pressure in the capsule 3423. As the pressure decreases, the supporting force of the capsule 3423 is weakened, and the buffer shock absorbing component 3 becomes harder. The support of the shock-absorbing component 3 for the treadmill body 1 will also become soft, so the vibration force generated during the movement of the treadmill body 1 will be transmitted to the upper connecting plate 31, and then transmitted to the piston rod 3436 through the connecting seat 341, so that the piston rod 3436 pushes the piston member 3435 to move in the liquid storage chamber 3433, and the energy dissipation spring 3437 contracts. Under the movement of the piston member 3435, the oil will be squeezed, so that the oil gradually passes through the hole cavity 3438 into the flow cavity 3434 formed between the annular partition plate 3432 and the fixed cylinder 3431. During the oil squeezing process, due to the The annular gap between the pistons 3435 is relatively large, and the oil is easily squeezed out. When the pistons 3435 continue to move, the annular gap becomes smaller and smaller, that is, the resistance of the pistons 3435 continues to increase. At the final stage of oil extrusion, the annular gap is zero, and the resistance is also stable at the maximum value. In addition, the oil consumes the kinetic energy of the force during the extrusion process, thereby achieving the effect of buffering and dissipating the force. Therefore, the wear of the treadmill body 1 caused by the vibration force and the counter-impact force of the treadmill body 1 on the human body can be reduced, and the pressure on the knee joint and the lumbar spine can be relieved. When the upper connecting plate 31 moves, the connecting rod 3511 connected to the upper support block 351 will push the guide column 354 to move on the surface of the support rod 353, and move the guide column 354 and the fixed seat 356, and squeeze the auxiliary limit spring 3510. Under the action of the auxiliary limit spring 3510, small impact forces can be buffered, and under the action of large impact forces, the guide column 354 will push the movable seat 357 to move, thereby contracting the main limit spring 358. Therefore, the large impact force can be buffered by the main limit spring 358, thereby meeting the purpose of buffering and shock absorbing of forces of different sizes.
