Description

Trainer with self-locking function

The present invention relates to a trainer, in particular a trainer with a self-locking function.

Existing fitness equipment, such as stretching trainers, usually requires a mechanism to provide movement resistance. The resistance mechanism is usually an elastic component, a weight block or a resistance wheel. In recent years, there have also been resistance mechanisms that use motors as fitness equipment. When using traditional weight equipment for rapid strength training, it is easy for the resistance at the weight end to increase sharply due to the increase in movement speed; using motors as the resistance mechanism of fitness equipment will not have this problem, and the resistance of the equipment can always remain balanced. Studies have shown that rapid strength training can not only improve absolute strength, but also explosive power, and explosive power means faster starting speed and faster reaction, which can help athletes gain advantages in training and competitions.

However, when the resistance motor is used as the resistance mechanism, when the user needs to leave temporarily or needs to shut down the fitness equipment for something, the resistance mechanism needs to be locked to prevent the fitness equipment from being touched by children and causing safety risks. In addition, during transportation, the resistance mechanism of the fitness equipment also needs to be locked to prevent the continuous vibration during transportation from damaging the resistance mechanism. In addition, when the fitness equipment encounters a sudden power outage or circuit failure, the resistance motor will fail due to the sudden power outage and lose resistance, causing the person using the sports equipment to suddenly accelerate under the action of inertia, resulting in safety risks. Therefore, how to manufacture fitness equipment with a self-locking function, with a higher degree of equipment integration and smaller space occupation, has always been the pursuit of the industry.

Therefore, the purpose of this new model is to provide a training device with a self-locking function that effectively provides safety protection for users in the event of a power outage without causing injuries.

Therefore, the new trainer with self-locking function includes a trainer body, a resistance mechanism, a pull rope assembly, a winding mechanism, and a self-locking driving mechanism.

The resistance mechanism is disposed in the main body of the trainer and is used to provide training in the trainer. The resistance mechanism includes a motor, which is used to provide resistance in the trainer and includes a stator assembly and a rotor assembly, and the rotor assembly can rotate relative to the stator assembly.

One end of the pull rope assembly is connected to the resistance mechanism, and the other end is connected to a force-applying member.

The winding mechanism is used for winding the pull rope assembly, and the winding mechanism is drivingly connected to the rotor assembly of the motor. The winding mechanism includes a winding drum, and at least one flange baffle at the outer end of the drum, and a first locking mating unit is provided on the at least one flange baffle.

The self-locking driving mechanism is used to perform locking and unlocking operations on the rotation of the rolling mechanism. The self-locking driving mechanism includes a driving unit and a second locking matching unit. The driving unit is used to drive the second locking matching unit to engage or separate with the first locking matching unit, thereby performing locking and unlocking operations on the rotation of the rolling mechanism.

The function of this new model is that when the user temporarily leaves or needs to shut down the trainer, the resistance mechanism can be automatically locked to prevent the trainer from being touched by children and causing safety risks.

Referring to Figures 1 to 9, an embodiment of the new trainer with a self-locking function includes a trainer body 3, a base 2, a resistance mechanism 1, an arm 4, a handle 5, a pull rope assembly 6, a display screen 7 and a pulley assembly 8.

The trainer body 3 is mounted on the base 2. The resistance mechanism 1 is arranged in the trainer body 3. The pull rope assembly 6 is connected to the resistance mechanism 1 at one end and to a force-applying member, such as a handle 5, at the other end. The resistance mechanism 1 is connected to the handle 5 through the pull rope assembly 6 and is used to provide training resistance in the trainer. Two arms 4 are arranged on the trainer body 3. The angle of each arm 4 relative to the trainer body 3 is adjustable. The arms 4 are arranged above the trainer body 3 in the height direction. Each arm 4 is a hollow structure with openings at both ends. The pull rope assembly 6 includes one or more pull ropes 611. At least one pulley of the pulley assembly 8 is arranged above the trainer body 3 in the height direction. The resistance mechanism 1 is arranged below the height direction of the trainer main body 3. The pull rope assembly 6 is wound around the pulley block 8 and passes through the arms 4, thereby connecting to the handle 5 arranged at the end of the arms 4. The pull rope assembly 6 is connected to the resistance mechanism 1 at one end through the pulley block 8, and is connected to the force member at the other end. The resistance mechanism 1 is arranged below the inside of the trainer main body 3, and the space above it can be used as the travel space of the pulley block 8. The layout is reasonable and the space utilization rate is high. According to the height of the user and the training speciality, the arms 4 can be adjusted up and down at multiple angles to meet the use of different heights and a variety of different training types.

In other embodiments, the handles 5 can be replaced with a variety of accessories, such as Y-shaped training handles, triceps training ropes, training belts, calf straps, thigh straps, and lightweight barbells, etc., to achieve seamless docking of a variety of special training items and to achieve training of special movements directly on the equipment.

Referring to Figures 1 and 2, in this embodiment, another pulley set (not shown) is provided at the end of each arm 4, so that the pull rope 611 can rotate according to the direction of the user's force, which not only maintains the comfort of the training, but also adapts to the changing direction of force in complex movements. At the same time, this design can also protect the equipment and the pull rope 611 and extend its service life.

The display screen 7 is arranged on the main body 3 of the trainer. The display screen 7 has multiple display areas (not shown), which can respectively display multiple data such as resistance, number of times, power, maximum explosive force, etc. The display screen 7 can include a processing chip, which is easy to use, can record previous data and settings, and can save each exercise record, so that users can download data without complicated operations, which is convenient for future analysis and research.

Referring to Figures 3 to 9, the resistance mechanism 1 includes a housing 10, a motor 20, a self-locking drive mechanism 30, a controller 40, a winding mechanism 50, and a guide mechanism 60. The motor 20 is used to provide resistance in fitness equipment, for example, as a resistance source for a stretching trainer. The controller 40 is electrically connected to the motor 20 and is used to control the size or direction of the resistance provided by the motor 20.

The motor 20, the self-locking drive mechanism 30 and the controller 40 are installed in the housing 10. The housing 10 is provided with a plurality of heat dissipation holes 12, and a heat dissipation fan 13 is fixedly provided to enhance the heat dissipation of the motor 20, the self-locking drive mechanism 30 and the controller 40. The motor 20 includes a stator assembly 21 and a rotor assembly 22. The stator assembly 21 is fixedly installed with the housing 10. The rotor assembly 22 can rotate relative to the stator assembly 21.

Referring to Figures 2 to 4, the trainer body 3 includes an outer shell 301. The outer shell 301 is provided with two sets of opposite external heat dissipation holes 302 along the heat dissipation airflow direction of the heat dissipation fan 13, thereby enhancing the heat dissipation of the resistance mechanism 1.

The winding mechanism 50 is used for winding the pull rope 611 at the force application end. The winding mechanism 50 is connected to the rotor assembly 22 of the motor 20. The winding mechanism 50 includes a winding drum 51 and at least one flange baffle 52 located at the outer end of the drum 51. The drum 51 and the flange baffle 52 form a winding space. A first locking mating unit 521 is provided on the flange baffle 52.

The winding mechanism 50 is connected to the rotor assembly 22 in a transmission manner, and the winding mechanism 50 can be directly connected to the rotor assembly 22, or the winding mechanism 50 can be connected to the rotor assembly 22 through a speed change assembly (not shown). The winding mechanism 50 can rotate together with the rotor assembly 22. The winding mechanism 50 is used to wrap around the pull rope 611 at the force application end of the fitness equipment, thereby providing resistance for the fitness equipment. As shown in FIG3, a wire outlet hole 11 is provided above the housing 10, so as to pass the pull rope 611 out. Preferably, the motor 20 is configured as a servo motor, so that the adjustment and control of the resistance are more precise.

Referring to Figures 3 to 6, the flange baffle 52 is disposed on one side of the drum 51. In some embodiments, two flange baffles 52 may also be disposed on both sides of the drum 51. The flange baffle 52 may serve as a baffle to facilitate the winding of the pull rope 611 on the drum 51, and may cooperate with the self-locking drive mechanism 30 to act as a locking member when the device requires the locking.

The self-locking drive mechanism 30 is used to perform locking and unlocking operations on the rotation of the rolling mechanism 50. The self-locking drive mechanism 30 includes a drive unit 31 and a second locking mating unit 32. The drive unit 31 is used to drive the second locking mating unit 32 to engage or separate with the first locking mating unit 521, thereby performing locking and unlocking operations on the rotation of the rolling mechanism 50.

The first locking and fitting unit 521 and the second locking and fitting unit 32 are a set of pins and pin holes that can be locked and fitted with each other. In this embodiment, the first locking and fitting unit 521 is configured as a plurality of brake pin holes arranged around the circumferential direction of the rotation center of the flange baffle 52. The second locking and fitting unit 32 is configured as a brake pin.

In some other embodiments, the self-locking drive mechanism 30 can be locked with the rotor assembly 22 of the motor 20, so that the resistance mechanism 1 is locked. However, the rotor assembly 22 of the motor 20 usually has a technical problem of large torque and high speed, which makes it difficult to lock. In this embodiment, the self-locking drive mechanism 30 cooperates with the flange baffle 52 of the winding mechanism 50 to achieve locking, and the locking torque generated is large, which makes it easier and more directly to lock and stop the winding mechanism 50, and the safety is higher.

The reel 51 and the flange baffle 52 form a winding space. The self-locking drive mechanism 30 is arranged within the span range of the winding space, that is, within the span range formed by the reel 51 and the flange baffle 52.

In some other embodiments, the self-locking drive mechanism 30 may be located outside the flange baffle 52 of the winding mechanism 50, that is, outside the range of the winding space. However, since the drum 51 is connected to one side of the rotor assembly 22 of the motor 20, there is a problem that the overall length of the motor 20 is too long; if the self-locking drive mechanism 30 is located outside the flange baffle 52 of the winding mechanism 50, the overall length of the motor 20 in the axial direction will be further increased, so that the outer dimensions of the product will be further increased. Therefore, in this embodiment, the self-locking drive mechanism 30 is arranged within the span of the winding space. Since the reel 51 has a relatively long length, the pull rope 611 cannot wrap around the entire reel 51. The outer ring of the reel 51 has a remaining winding space, and the remaining winding space can be fully utilized to arrange the self-locking drive mechanism 30, so that the overall size of the product can be reduced, and the miniaturization of the product can be achieved.

Referring to Figures 2 and 3, the housing 10 is a rectangular parallelepiped structure, and the motor 20 is arranged in the housing 10. The axial direction of the motor 20 is parallel to the length direction of the housing 10, thereby making full use of the space of the housing 10.

Referring to Figures 1 and 2, the arms 4 are respectively arranged in the left and right directions of the trainer main body 3, and the left and right directions of the trainer main body 3 are defined as the width direction of the trainer main body 3. The resistance mechanism 1 is arranged in the trainer main body 3, and the length direction of the resistance mechanism 1 is aligned with the width direction of the trainer main body 3, so that the size of the trainer main body 3 is smaller and the overall space occupied is smaller.

In this embodiment, as shown in FIG. 5 , the self-locking drive mechanism 30 is roughly within the axial projection range of the winding mechanism 50 or the rotor assembly 22, thereby making full use of the remaining winding space and improving the miniaturization of the product.

In addition, the self-locking driving mechanism 30 is located on the side opposite to the wire outlet direction relative to the reel 51. In this embodiment, the wire outlet direction is upward, and the self-locking driving mechanism 30 is located below the reel 51, so that the remaining winding space is fully utilized and the normal wire outlet of the pull rope 611 is not interfered.

Referring to Figures 4 and 5, a guide mechanism 60 is provided between the outlet hole 11 and the drum 51. The guide mechanism 60 includes a guide roller 61. As shown in Figures 4 and 9, the pull rope 611 passes through the guide roller 61 and then passes through the outlet hole 11 to the outside of the housing 10. The guide mechanism 60 can guide the pull rope 611 on the drum 51 during the process of passing through the housing 10, so that the pull rope 611 can be accurately aligned with the outlet hole 11, preventing the pull rope 611 from scratching the housing 10 and causing wear and affecting the service life.

Referring to FIG. 7 and FIG. 8 , the driving unit 31 includes a mounting frame 312, a spring 311, and an electromagnetic iron assembly 313. The mounting frame 312 is fixedly mounted on the housing 10. The electromagnetic iron assembly 313 is electrically connected to the controller 40. The second locking mating unit 32 can be slidably mounted on the mounting frame 312, and the second locking mating unit 32 can slide out of one end of the mounting frame 312 and can be inserted into the first locking mating unit 521. One end of the spring 311 is connected to the mounting frame 312, and the other end is connected to the second locking mating unit 32, so as to apply an elastic force F1 toward the flange baffle 52 to the second locking mating unit 32. The electromagnetic iron assembly 313 acts on the second locking mating unit 32 and applies an electromagnetic force F2 to the second locking mating unit 32 in a direction away from the flange baffle 52. The electromagnetic force F2 is greater than the elastic force F1, so when the fitness equipment is normally powered, the electromagnetic iron assembly 313 is energized to generate an electromagnetic force F2 that can overcome the elastic force F1, so that the second locking mating unit 32 retracts and separates from the first locking mating unit 521 of the flange baffle 52. When the fitness equipment is suddenly powered off, the electromagnetic iron assembly 313 loses power and does not generate electromagnetic force. The second locking matching unit 32 moves toward the flange baffle 52 under the elastic force F1 of the spring 311, so that the second locking matching unit 32 is locked into the corresponding first locking matching unit 521 due to the elastic force F1, thereby braking the moving rotor assembly 22 and the reel 51 to stop moving, preventing the fitness equipment from losing resistance due to sudden power failure and generating safety risks. That is, the self-locking drive mechanism 30 performs a locking operation on the rotation of the winding mechanism 50 due to the power-off state. In other embodiments, the spring 311 can also be other elastic elements, such as an elastic tube. In this embodiment, the self-locking drive mechanism 30 is electrically connected to the controller 40; the self-locking drive mechanism 30 can also perform locking and unlocking operations on the rotation of the rolling mechanism 50 after receiving the control signal of the controller 40. When the fitness equipment is set to at least one of the following states, the controller 40 sends a control signal to perform a locking operation on the rotation of the rolling mechanism 50: temporary leave state, shutdown state or transportation state. In this way, when the fitness person needs to temporarily leave or shut down the fitness equipment for something, the resistance mechanism 1 can be actively locked to prevent the fitness equipment from being touched by children and causing safety risks. In addition, during transportation, the resistance mechanism 1 of the fitness equipment can also be actively locked to prevent the resistance mechanism 1 from being damaged by continuous vibration during transportation.

Referring to FIG. 10 , in other embodiments, a resistance mechanism 1′ further includes a human-machine interaction device 70. The human-machine interaction device 70 is disposed on the housing 10 to adjust and display the working parameters of the resistance mechanism 1′. The human-machine interaction device 70 is configured as a shuttle display assembly, and the human-machine interaction device 70 is electrically connected to the controller 40, and includes a shuttle 71 and a display device 72 disposed on the front of the shuttle 71. The shuttle 71 can be used to adjust various working parameters of the resistance mechanism 1, such as resistance, times and power. The display device 72, such as an electronic watch, can display multiple data such as resistance, times, power, maximum explosive force, etc. Of course, as shown in Figure 3, the resistance mechanism 1' may not be provided with the human-machine interaction device 70, and control and display can be achieved through the overall control of the fitness equipment itself and the display device 72.

In other embodiments, the self-locking drive mechanism 30 may be a friction clutch mechanism or a magnetic clutch mechanism. That is, the self-locking drive mechanism 30 brakes and stops the winding mechanism 50 through the friction clutch mechanism or the magnetic clutch mechanism.

Referring to Figures 3 to 6, in this embodiment, the reel 51 is connected to one side of the rotor assembly 22 of the motor 20, and the flange baffle 52 is disposed on the side of the reel 51 away from the motor 20, so that the first locking matching unit 521 can be closer to the rotation center and arranged along the circumferential direction of the flange baffle 52, and the self-locking drive mechanism 30 cooperates with the first locking matching unit 521, so that the overall product size is more compact and the space utilization rate is higher.

Of course, in some embodiments, the housing 10 may not be provided, and the motor 20, the self-locking drive mechanism 30, the controller 40 and the rolling mechanism 50 may be directly integrated into the fitness equipment, which is also a feasible technical solution.

Referring to Figures 6 to 8, a proximity switch 35 is also provided at the other end of the mounting frame 312. The proximity switch 35 can be a photoelectric switch, etc. When the second locking mating unit 32 retracts and separates from the first locking mating unit 521, a tail 321 of the second locking mating unit 32 extends out of the mounting frame 312 and actuates the proximity switch 35 to generate an electrical signal. The proximity switch 35 is connected to the controller 40. The controller 40 controls the motor 20 to start only after receiving the electrical signal generated by the proximity switch 35. This prevents the motor 20 from being started when the second locking mating unit 32 is inserted into the corresponding first locking mating unit 521, thereby preventing damage to the equipment and related safety risks.

In addition, although the above embodiment is illustrated by using an upright training device as an example, the resistance mechanism 1 can also be applied to other types of training devices because it has the function of realizing self-locking. For example, referring to FIG. 11 , a multifunctional training device 100 is shown, which includes a resistance mechanism 1 ', a pull rope assembly 6', a pulley assembly 8' and a plurality of different types of force applying members 5'. The resistance mechanism 1' is connected to different types of force-applying members 5' through the pull rope assembly 6' and different pulley sets 8', respectively, so as to provide movement resistance for the user when performing different training movements; for example, referring to FIG. 12, it shows another multifunctional trainer 200, including the resistance mechanism 1', a pull rope assembly 6", a pulley set 8" and multiple different types of force-applying members 5" (such as handles, tension straight bars, tension bending bars, lying handles, etc.), and the resistance mechanism 1' is connected to different types of force-applying members 5" through the pull rope assembly 6" and different pulley sets 8", respectively, so as to provide movement resistance for the user when performing different training movements, respectively, and the design effectively provides safety protection for the user in the event of a power outage without injury.

Through the above description, the advantages of the aforementioned embodiments can be summarized as follows:

1. When the fitness personnel need to leave temporarily or need to shut down the fitness equipment, the resistance mechanism 1, 1' can be locked actively to prevent the fitness equipment from being touched by children and causing safety risks. In addition, during transportation, the resistance mechanism 1, 1' of the fitness equipment can also be locked actively to prevent the resistance mechanism 1, 1' from being damaged by continuous vibration during transportation.

2. The self-locking drive mechanism 30 is located within the span of the winding space, so that the winding space can be used to arrange the self-locking drive mechanism 30, so that the overall size of the resistance mechanism 1, 1' with the self-locking function is smaller, which is conducive to the full utilization of the space of the fitness equipment and the miniaturization of the product. The axial direction of the motor 20 is parallel to the length direction of the housing 10, and the length direction of the resistance mechanism 1 is aligned with the length direction of the trainer body 3, so that the size of the trainer body 3 is smaller and the overall space occupied is smaller.

3. When the fitness equipment suddenly loses power, the electromagnetic iron assembly 313 loses power and does not generate electromagnetic force. The second locking mating unit 32 moves toward the flange baffle 52 under the elastic force of the spring 311, so that the second locking mating unit 32 is clamped into the first locking mating unit 521 due to the elastic force, thereby braking the moving rotor assembly 22 and the winding mechanism 50 to stop moving, preventing the fitness equipment from losing resistance due to sudden power failure and causing safety risks.

However, the above is only an example of the implementation of this new model, and it cannot be used to limit the scope of the implementation of this new model. All simple equivalent changes and modifications made according to the scope of the patent application of this new model and the content of the patent specification are still within the scope of this new patent.
