[0001] The invention relates to the technical field of fitness equipment, and in particular to an inching brake assembly and a rope-pulling fitness training device. Background Art

[0002] With the improvement of living standards and people's increasing awareness of their own health, more and more people are starting to do strength training. Strength training can exercise the body, strengthen human muscles, and improve human metabolism.

[0003] The existing rope-pulling fitness training device that uses a motor to provide resistance is very likely to cause a safety accident if a power outage or force overload occurs during the user's training, causing great harm to the user's personal safety and the training device itself. Therefore, a braking device is needed to brake the training device in time when the above special situation occurs.

[0004] Conventional existing brake technologies are mainly divided into two categories: friction type and latch type. The friction type uses the mutual friction between friction plates to complete the braking action, but the brake device has a complex structure, large size, high cost, and requires regular adjustment of the spacing between the friction plates, which is not suitable for rope-pulling fitness training devices. Existing latch-type brake devices generally use electromagnets that can be powered for a long time as the power source for the braking action. When powered on, the latch is in a retracted state. When the power is off or a signal is received, the latch pops out. This type of device requires the electromagnet to be powered on for a long time. In order to prevent the coil from burning, the electromagnet is larger in size and more expensive than the coil of an ordinary electromagnet. Moreover, the electromagnet is always powered on and is in a power-consuming state, wasting energy. And when the latch is not exactly aligned with the matching brake disc, the latch is blocked and cannot complete the pop-up action, and the brake device will fail. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a point-actuated brake assembly and a rope-pulling fitness training device, so that the brake assembly is more stable, energy-saving and smaller in size.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0011] The second elastic member is located in the hollow cylinder and has two ends respectively in contact with the flange and the slider;

[0012] The latch buckle comprises a first matching piece and a second matching piece connected by a buckle, wherein the first matching piece is arranged on the outer wall of the hollow cylinder toward the slider, and the second matching piece is connected to an end of the slider exposed from the hollow cylinder and faces the first matching piece;

[0013] The push-pull electromagnet is arranged on a side of the slider away from the latch buckle, and the slider is within the push-pull distance of the push-pull rod of the push-pull electromagnet.

[0014] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0015] A rope-pulling fitness training device comprises a housing, a resistance assembly, a spool, a brake disc and a brake assembly arranged in the housing, wherein the spool is rotatably arranged in the housing, and the brake assembly is the above-mentioned inching brake assembly;

[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0026] Please refer to Figure 1 and Figure 2 , a jog brake assembly, comprising a brake pin, a brake base, a latch buckle, a slider, a push-pull electromagnet, a first elastic member and a second elastic member, wherein the elasticity of the second elastic member is greater than that of the first elastic member;

[0027] The brake base is provided with a hollow cylinder, one end of the hollow cylinder is provided with a first through hole corresponding to the shape of the brake pin, and the other end is provided with a second through hole;

[0028] One end of the brake pin is located in the hollow cylinder and is surrounded by a flange, and the first elastic member is located in the hollow cylinder and has two ends that are in contact with the flange and one end of the hollow cylinder where the first through hole is located;

[0029] One end of the slider is located in the hollow cylinder near one end of the second through hole and corresponds to the shape of the second through hole, and the other end of the slider extends out of the hollow cylinder, and the slider can slide along the hollow cylinder;

[0030] The second elastic member is located in the hollow cylinder and has two ends respectively in contact with the flange and the slider;

[0031] The latch buckle comprises a first matching piece and a second matching piece connected by a buckle, wherein the first matching piece is arranged on the outer wall of the hollow cylinder toward the slider, and the second matching piece is connected to an end of the slider exposed from the hollow cylinder and faces the first matching piece;

[0032] The push-pull electromagnet is arranged on a side of the slider away from the latch buckle, and the slider is within the push-pull distance of the push-pull rod of the push-pull electromagnet.

[0033] From the above description, it can be seen that the beneficial effects of the present invention are: the present invention does not require the electromagnet to be energized for a long time, and the electromagnet is energized only when braking is needed. The braking action can be completed by controlling the electromagnet to perform a single inching action. Since the elasticity of the second elastic member is greater than that of the first elastic member, when the brake pin is not aligned with the brake disc, the two elastic members act on the brake pin to keep it moving forward until the brake pin is aligned with the brake disc and the brake pin pops out and cooperates with the brake disc to achieve braking. Therefore, the braking action can be completed at any time without the need to align the pin with the brake disc. The device of the present invention has a simple structure. Due to the elastic space provided by the second elastic member, the brake pin will not be unable to pop out, the performance is more reliable, and the electromagnet is smaller in size and the installation volume is also smaller.

[0034] Furthermore, the hollow cylinder is provided with a sliding opening along the cylinder direction and communicating with the second through hole on the cylinder wall near the second through hole, and the middle part of the sliding block is slidably connected to the sliding opening.

[0035] From the above description, it can be seen that the middle part of the slider is slidably connected to the sliding opening on the hollow cylinder, so that the slider can slide along the sliding opening, thereby squeezing and pushing the second sliding member to make the brake pin extend out of the first through hole.

[0036] Furthermore, it also includes a fixing piece, which is arranged on the outer wall of the hollow cylinder and has a fixing through hole, and grooves are provided on both sides of the first matching piece, and the first matching piece is fixedly connected to the hollow cylinder by snapping the grooves with the fixing through holes.

[0037] It can be seen from the above description that a fixing member is also provided, through which the first matching member is fixed to ensure the stability of the first matching member.

[0038] Furthermore, the first matching piece is a latch buckle body, and the second matching piece is a latch buckle bumper, and the latch buckle bumper is connected to the latch buckle body in a matching manner.

[0039] It can be seen from the above description that the first matching piece is the latch buckle body and the second matching piece is the latch buckle head, which is a specific embodiment of the present invention.

[0040] Please refer to Figure 3 and Figure 4 A rope-pulling fitness training device comprises a housing, a resistance assembly, a spool, a brake disc and a brake assembly arranged in the housing, wherein the spool is rotatably arranged in the housing, and the brake assembly is one of the above-mentioned inching brake assemblies;

[0041] The resistance assembly is transmission-connected to the spool to provide a preset resistance to the rotation of the spool, the spool is connected to a brake disc, the edge of the brake disc is evenly surrounded by brake grooves, the brake assembly is arranged on one side of the brake disc, and the brake pin faces the brake disc, and can be stuck in the brake groove on the edge of the brake disc when the brake pin pops out;

[0042] A drawstring is wound around the spool, and the drawstring extends out of the box shell from a through hole on the box shell.

[0043] From the above description, it can be seen that the beneficial effects of the present invention are: the present invention does not require the electromagnet to be energized for a long time. The electromagnet is energized only when braking is needed. The braking action can be completed by controlling the electromagnet to perform a single inching action. Since the elasticity of the second elastic member is greater than that of the first elastic member, when the brake pin is not aligned with the brake disc, the two elastic members act on the brake pin to keep it moving forward until the brake pin is aligned with the brake disc and the brake pin pops out and cooperates with the brake disc to achieve braking. Therefore, the braking action can be completed at any time without the need to align the pin with the brake disc. The device of the present invention has a simple structure. Due to the elastic space provided by the second elastic member, the brake pin will not be unable to pop out, and the performance is more reliable. The electromagnet is smaller in size, and the installation volume is also smaller, which can reduce the space occupied by the rope-pulling fitness training device.

[0044] Furthermore, it also includes a clutch drive device, a first clutch and a second clutch;

[0045] One end of the first clutch is connected to the resistance assembly, and the other end is connected to the spool;

[0046] The number of the spool, the first clutch and the resistance assembly is more than two, the second clutch is connected to all the resistance assemblies at the same time, when the second clutch is in a closed state, at least two of the resistance assemblies are transmission-connected, and when the second clutch is in a disengaged state, the transmission connection between at least two of the resistance assemblies is disconnected;

[0047] The clutch control assembly is connected to the second clutch and the first clutch respectively.

[0048] From the above description, it can be known that the present invention can control the opening and closing of the first clutch and the second clutch through the clutch driving device. When only one of the first clutch is closed and the second clutch is closed, since the second clutch is connected to multiple resistance components, the multiple resistance components are transmitted to the spool at the closing position of the first clutch through the second clutch, thereby realizing high-strength training of one hand, and when the first clutch is closed and the second clutch is separated, each resistance component is respectively transmitted to the corresponding spool through the first clutch, and each spool corresponds to a resistance component, thereby realizing refined training of both hands; through the adjustable training mode, it can meet the different needs of users and improve the user experience.

[0049] Furthermore, the resistance assembly includes a resistance motor and a transmission assembly, the transmission assembly includes a third transmission gear and a fourth transmission gear that are meshed and connected, the third transmission gear is connected to the resistance motor, and the fourth transmission gear is connected to the first clutch.

[0050] It can be seen from the above description that the present invention generates power through the resistance motor and transmits it to the spool through the third transmission gear and the fourth transmission gear, thereby generating resistance to meet the user's exercise needs.

[0051] Furthermore, the first clutch, the resistance assembly and the spool are provided in two groups in opposite directions and in parallel.

[0052] From the above description, it can be seen that the first clutch, the resistance assembly and the spool are in two groups and are arranged side by side, which minimizes the thickness of the device, reduces the overall volume, and realizes the miniaturization of the device.

[0053] Furthermore, it also includes a speed measuring component and a force measuring component. The speed measuring component is connected to the resistance component. The pull rope is respectively wrapped around the force measuring component in the box shell and then extends out of the box shell through the through hole on the box shell.

[0054] From the above description, it can be seen that it also includes a speed measuring component and a force measuring component. The speed measuring component can measure the rotation speed of the spool, and the force measuring component can effectively measure the tension of the pull rope. It can sense whether there is an abnormality in the equipment. If an abnormality occurs, the braking device can be triggered in time, which can ensure the user's safety to a certain extent and improve the user experience.

[0055] Furthermore, each of the force measuring assemblies includes two pulleys and a force sensor, the force sensor is connected to a pulley, and the pull rope is alternately wound around the two pulleys.

[0056] It can be seen from the above description that the stretching is guided by two pulleys, so that the force sensor can better measure the tension value of the stretching.

[0057] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the present invention is:

[0058] A jog brake assembly comprises a brake pin 1, a brake base, a latch buckle, a slider 2, a push-pull electromagnet 3, a first elastic member 4 and a second elastic member 5, wherein the elasticity of the second elastic member 5 is greater than that of the first elastic member 4.

[0059] Among them, a hollow cylinder 6 is provided on the brake base, one end of the hollow cylinder 6 is provided with a first through hole 7 corresponding to the shape of the brake pin 1, and the other end is provided with a second through hole 8; one end of the brake pin 1 is located in the hollow cylinder 6 and is surrounded by a flange 9, the first elastic member 4 is located in the hollow cylinder 6 and its two ends are in contact with the flange 9 and the end of the hollow cylinder 6 where the first through hole 7 is located; the second elastic member 5 is located in the hollow cylinder 6 and its two ends are respectively in contact with the flange 9 and the slider 2.

[0060] like Figure 1 As shown, one end of the slider 2 is located in the hollow cylinder 6 close to one end of the second through hole 8 and corresponds to the shape of the second through hole 8 , and the other end of the slider 2 extends out of the hollow cylinder 6 , and the slider 2 can slide along the hollow cylinder 6 .

[0061] The latch includes a first mating piece 10 and a second mating piece 11 which are connected by a snap connection. The first mating piece 10 is arranged on the outer wall of the hollow cylinder 6 toward the slider 2 . The second mating piece 11 is connected to one end of the slider 2 which is exposed from the hollow cylinder 6 and faces the first mating piece 10 .

[0062] The push-pull electromagnet 3 is arranged on a side of the slider 2 away from the latch buckle, and the slider 2 is within the push-pull distance of the push-pull rod of the push-pull electromagnet 3 .

[0063] In this embodiment, the first elastic member 4 and the second elastic member 5 are both springs. In other equivalent embodiments, they can also be replaced by other elastic materials as long as they can rebound when compressed.

[0064] Among them, the operating principle of an inching brake assembly is:

[0065] When braking is needed, the push-pull electromagnet 3 is energized. After being energized, the push-pull electromagnet 3 extends a push-pull rod to push the slider 2. The slider 2 moves along the hollow cylinder 6, thereby compressing the second elastic member 5. The second matching member 11 connected to the part of the slider 2 exposed from the hollow cylinder 6 contacts and is matched with the first matching member 10 of the latch buckle. At this time, the second elastic member 5 is compressed and its elastic force is greater than that of the first elastic member 4, pushing the brake pin 1 to pop out and brake. Since the elasticity of the second elastic member 5 is greater than that of the first elastic member 4, when the brake pin 1 is not aligned with the brake disc, the brake pin 1 is pushed out. When the brake pin 1 is aligned with the brake disc, the two elastic members act on the brake pin 1 to keep it moving forward until the brake pin 1 is aligned with the brake disc. The brake pin 1 and the brake disc cooperate to achieve braking, so the braking action can be completed at any time; when braking is not needed, the push-pull electromagnet 3 is energized again. After energization, the push-pull electromagnet 3 extends the push-pull rod to push the slider 2 again. Through the characteristics of the lock buckle, the first matching member 10 and the second matching member 11 are separated. At this time, the second elastic member 5 and the first elastic member 4 rebound, so that the slider 2 and the brake pin 1 are reset, and the braking is ended.

[0066] Please refer to Figure 1 and 2 , Embodiment 2 of the present invention is:

[0067] A momentary brake assembly, which differs from the first embodiment in that it further includes a fixing member 12, a hollow cylinder 6 is provided with a sliding opening 13 along the cylinder direction and connected to the second through hole 8 on the cylinder wall near the second through hole 8, and the middle part of the slider 2 is slidably connected to the sliding opening 13.

[0068] The fixing member 12 is arranged on the outer wall of the hollow cylinder 6 and is provided with a fixing through hole. The first matching member 10 is provided with grooves on both sides and is fixedly connected with the hollow cylinder 6 by snapping the grooves with the fixing through holes.

[0069] In this embodiment, the first mating piece 10 is the latch buckle body, and the second mating piece 11 is the latch buckle head. In other equivalent embodiments, the first mating piece 10 and the second mating piece 11 can also be the latch buckle head and the latch buckle body, respectively, similar to the push-type bead rebounder in the prior art.

[0070] Please refer to Figure 3 , Embodiment 3 of the present invention is:

[0071] A rope-pulling fitness training device, such as Figure 3As shown, it includes a box shell 14 and a resistance component 18, a spool 15, a brake disc 16 and a brake component 17 arranged in the box shell 14. The spool 15 is rotatably arranged in the box shell 14, and the brake component 17 is an inching brake component of the above-mentioned embodiment one or two.

[0072] like Figure 3 As shown, the resistance assembly 18 is transmission-connected to the spool 15 to provide a preset resistance to the rotation of the spool 15. The spool 15 is connected to the brake disc 16. The edge of the brake disc 16 is evenly surrounded by brake grooves. The brake assembly 17 is arranged on one side of the brake disc 16, and the brake pin 1 faces the brake disc 16. When the brake pin 1 pops out, it can be stuck in the brake groove at the edge of the brake disc 16.

[0073] The spool 15 is connected and wound with a drawstring, and the drawstring extends out of the box shell 14 through a through hole on the box shell 14 . What is not shown in the figure is that a handle is connected to one end of the drawstring extending out of the box shell 14 .

[0074] Please refer to Figure 3 and Figure 4 , Embodiment 4 of the present invention is:

[0075] A rope-pulling fitness training device, which differs from the third embodiment in that it further comprises a clutch drive device 19 , a first clutch 20 and a second clutch 21 .

[0076] The number of the spool 15, the first clutch 20 and the resistance assembly 18 are all more than two. Figure 4 As shown, the resistance assembly 18 includes a resistance motor 22 and a transmission assembly, and the transmission assembly includes a first transmission gear 23 and a second transmission gear 24 that are meshed and connected. The first transmission gear 23 is connected to the resistance motor 22, and the second transmission gear 24 is connected to the first clutch 20. The second clutch 21 is connected to all resistance assemblies 18 at the same time. When the second clutch 21 is in a closed state, at least two of the resistance assemblies are connected in transmission. When the second clutch 21 is in a disengaged state, the transmission connection between at least two of the resistance assemblies is disconnected.

[0077] In this embodiment, the number of the spool 15, the first clutch 20 and the resistance assembly 18 is two groups and they are arranged side by side in opposite directions, so that the width of the housing 14 only needs to meet the width of one group of the first clutch 20, the resistance assembly 18 and the spool 15, thereby realizing the miniaturization of the device.

[0078] In this embodiment, the clutch drive device 19 is connected to the second clutch 21 and the first clutch 20, respectively. Thus, the first clutch 20 and the second clutch 21 can be opened and closed by the clutch drive device 19. When only one of the first clutch 20 is closed and the second clutch 21 is closed, since the second clutch 21 is connected to the two resistance components 18, the two resistance components 18 are transmitted to the spool 15 at the closing position of the first clutch 20 through the second clutch 21, thereby realizing high-strength training of one hand. When both of the first clutches 20 are closed and the second clutch 21 is separated, the two resistance components 18 are respectively transmitted to the corresponding spools 15 through the first clutch 20, and each spool 15 corresponds to a resistance component 18, thereby realizing refined training of both hands.

[0079] Please refer to Figure 4 , Embodiment 5 of the present invention is:

[0080] A rope-pulling fitness training device, which differs from the fourth embodiment in that it also includes a speed measuring component 25 and a force measuring component 26. The speed measuring component 25 is connected to the second transmission gear 24. Each force measuring component 26 includes two pulleys 27 and a force sensor 28. The force sensor 28 is connected to a pulley 27. The pull rope is alternately wound around the two pulleys 27 and then extends out of the box shell 14 through the through hole on the box shell 14.

[0081] Among them, the speed measuring component 25 is installed next to the second transmission gear 24 to monitor the rotation speed of the spool 15 in real time. When it is detected that the rotation speed of the spool 15 exceeds the threshold and the force measuring component 26 detects that the tension is instantly reduced, the control panel will drive the brake component 17 to lock the spool 15 to prevent the rapid swing of the handle from causing harm to the user.

[0082] The two pulleys 27 allow the rope to pass through at a specific angle. When the rope is pulled, it will generate a pulling force on the pulley 27. After the force sensor 28 connected to the pulley 27 measures the pulling force, the pulling force of the rope is obtained through mathematical calculation. After the pulling force is obtained, the value is displayed on the terminal and a curve is drawn. The real-time curve can be compared with the standard curve to determine whether the force and rhythm meet the action requirements. At the same time, the real-time pulling force value will also participate in the control of the motor, so that the resistance of the motor can be accurately controlled, achieving the effect of completely simulating the load of the metal block.

[0083] In summary, the present invention provides a kind of inching brake assembly and a pull-rope fitness training device. The present invention does not need the electromagnet to be energized for a long time. The electromagnet is energized only when braking is needed. The braking action can be completed by controlling the electromagnet to perform a single inching action. Since the elasticity of the second elastic member is greater than that of the first elastic member, when the brake pin is not aligned with the brake disc, the two elastic members act on the brake pin to keep it moving forward until the brake pin is aligned with the brake disc and the brake pin pops out and cooperates with the brake disc to achieve braking. Therefore, the braking action can be completed at any time without the need to align the pin with the brake disc. The device of the present invention has a simple structure. Due to the elastic space provided by the second elastic member, the brake pin will not be unable to pop out, and the performance is more reliable. The electromagnet is smaller in size, and the installation volume is also smaller. The pull-rope fitness training device can control the opening and closing of the first clutch and the second clutch through the clutch drive. Only one of the clutches is closed. When the second clutch is closed, since the second clutch is connected to multiple resistance components, the multiple resistance components are transmitted to the spool at the closed position of the first clutch through the second clutch, thereby realizing high-strength training of one hand, and when the first clutch is closed and the second clutch is separated, each resistance component is respectively transmitted to the corresponding spool through the first clutch, and each spool corresponds to a resistance component, thereby realizing refined training of both hands; through the adjustable training mode, it can meet the different needs of users, and the number of the first clutch, resistance components and spools is two groups and arranged side by side, which minimizes the thickness of the device, reduces the overall volume, and realizes miniaturization of the device, and also provides a speed measuring component and a force measuring component, which can measure the rotation speed of the spool and the tension of the rope, and sense whether there is any abnormality in the equipment, and then trigger the brake device in time, which can ensure the safety of the user to a certain extent and improve the user experience.
