Based on this, the arm control component can control the driving device to drive the ejectable device to eject the arm from the inner liner to the body of the training device through the ejection channel, and attack the human body. The user cannot predict the arm of the combat training device of this application. The attack time, therefore, the combat training device of the present application can exercise the user's reaction ability.

It should be noted that the arm control component 6 can have various combinations, for example, it can be a combination of a human body position sensor and a controller, a touch screen and a controller and a combination, or a combination of a human body position sensor, a touch screen, and a controller. .

When the arm control component includes a human body position sensor and a controller, the human body position sensor is connected to the controller. After the human body position sensor detects the human body position, it sends a human body position signal to the controller, and then the controller controls the driving device to drive according to the human body position signal Can eject the device.

The human body motion signal analyzes the human body motion, so as to control the driving device to drive the ejectable device to eject or retract the arm according to the human body motion.

This embodiment uses a specific arm and its corresponding pop-up device as an example to describe the combat training equipment in detail.

Please refer to FIG. 2, which is a schematic structural diagram of a pop-up device according to Embodiment 1 of the present application.

Wherein, the ejectable device includes: a disc 3054, a first electromagnet 3062, a second elastic member 3063, and a top rod 3064;

The disc 3054 is fixed on the driving device; the disc 3054 is driven by the driving device to rotate;

The first electromagnet 3062, the second elastic member 3063, and the top rod 3064 are fixed on the disc 3054. One end of the second elastic member 3063 is connected to the first electromagnet 3062, and the other end Connected to the first end of the top rod 3064;

The arm 4 is provided with a groove that matches with the top rod 3064;

Specifically, the operation process of the ejectable device provided in this application is as follows:

With the rotation of the disc, the disc, the first electromagnet, the second elastic member and the ejector rod are also continuously rotating, and the orientation of the ejector rod is constantly changing. Refer to Figure 2, at this time, the arm is in a contracted state. As the disk rotates clockwise, the direction of the ejector rod becomes toward the groove on the arm. At this time, the first electromagnet loses its magnetism, and the ejector rod is ejected under the action of the second elastic member and falls into the groove. As the disc rotates clockwise, the ejector rod drives the arm to eject. Referring to FIG. 3, when the first electromagnet is magnetic, the ejector rod, the second elastic member and the first electromagnet are attracted together, and the second end of the ejector rod is separated from the groove. It should be noted that after the second end of the ejector rod is separated from the groove, the arm starts to retract under the action of the first elastic member.

In addition, the embodiment of the present application can also bend the arm during the ejection process through the pop-up bending device.

In addition, there may be a variety of driving devices. For example, the first driving device, as shown in FIGS. 4 and 5, may include: a pendulum 301 that swings with the action of the combat training equipment, a first ratchet mechanism 302; A ratchet mechanism includes a first ratchet 3021, a first pawl 3022, and a first pawl fixing structure 3023 that is rotatably fixed coaxially with the first ratchet; one end of the first pawl is fixed to the first ratchet On the pawl fixing structure, the other end abuts against any tooth groove of the first ratchet; the first pawl fixing structure is fixedly connected to the pendulum through a pendulum rod, so that the first pawl fixing structure Follow the swing of the pendulum to rotate; the dynamic drive device further includes an energy storage structure connected with the first ratchet transmission and a power output structure connected with the output end of the energy storage structure, the energy storage The structure is used for storing the mechanical energy generated by the rotation of the first ratchet wheel and outputting the stored mechanical energy to the power output structure; the power output structure is connected with the rotation fixing part to drive the rotation fixing part.

When the combat training equipment moves when the user exerts force, the pendulum will swing with the action, thereby driving the first pawl fixing structure to rotate. Since one end of the first pawl is fixed on the first pawl fixing structure, The other end abuts in any tooth groove of the first ratchet wheel. Therefore, when the first pawl fixing structure rotates, one end of the first pawl against any tooth groove of the first ratchet wheel will push the first ratchet wheel to rotate Since the energy storage structure is connected to the first ratchet in transmission, the energy storage structure stores the mechanical energy of the rotation of the first ratchet in order to output and provide power.

Further, as shown in Figures 6 and 7, the first drive device may further include: a first bevel gear 306, a second bevel gear 307, a third bevel gear 308, and a second ratchet mechanism 309; The two ratchet mechanism includes a second ratchet 3091, a second pawl 3092, and a second pawl fixing structure 3093 that is rotatably fixed coaxially with the second ratchet; one end of the second pawl is fixed to the second ratchet On the pawl fixing structure, the other end abuts against any tooth groove of the second ratchet; the second pawl fixing structure is fixedly connected with the pendulum through a pendulum rod, so that the second pawl fixing structure Follow the swing of the pendulum to rotate; the first bevel gear and the first ratchet are synchronously transmitted and arranged; the second bevel gear and the second ratchet are synchronously transmitted and arranged; the first cone The gear and the second bevel gear mesh with the third bevel gear, so that when the first bevel gear rotates, the third bevel gear drives the second bevel gear in accordance with the The first bevel gear rotates in the opposite direction of rotation; the direction in which the first pawl pushes the first ratchet wheel is opposite to the direction in which the second pawl pushes the second ratchet wheel.

It should be noted that, since the swing of the pendulum is in two directions of "coming" and "returning", this embodiment describes the swinging direction of the pendulum as the first direction and the second direction.

When the user exerts force to cause the motion equipment to move, the pendulum will swing accordingly. When the pendulum swings in the first direction, the first pawl fixing structure and the second pawl fixing structure will follow the pendulum to rotate in the same direction. When the first pawl will push the first ratchet to rotate, the mechanical energy generated by the rotation of the first ratchet is stored in the energy storage structure; because the first pawl pushes the first ratchet in the opposite direction and the second pawl pushes the second ratchet in the opposite direction Therefore, when the first pawl pushes the first ratchet wheel, the second pawl slips on the second ratchet wheel, and the second pawl will not push the second ratchet wheel to rotate.

When the pendulum swings in the second direction, the first pawl fixing structure and the second pawl fixing structure will follow the pendulum to rotate in the same direction. At this time, the second pawl pushes the second ratchet wheel to rotate, and the first pawl is in the first A ratchet is slipping. Because the second bevel gear and the second ratchet are in synchronous transmission, when the second ratchet rotates, it will synchronously drive the second bevel gear to rotate, which in turn drives the third bevel gear meshing with the second bevel gear. The gear rotates, and the first bevel gear meshed with the third bevel gear is further driven to rotate in the direction opposite to the rotation direction of the second bevel gear. Because the first bevel gear and the first ratchet gear are synchronously driven, the first bevel gear A ratchet will follow the first bevel gear to rotate synchronously, and because the first bevel gear and the second bevel gear rotate in opposite directions, the first ratchet still rotates in the same direction as when the pendulum swings in the first direction. The ratchet wheel rotates in the same direction, and at this time, mechanical energy rotating in the same direction is still provided to the energy storage structure.

Therefore, regardless of whether the pendulum swings in the first direction or the second direction, the first ratchet will provide the energy storage structure with mechanical energy in the same rotation direction, thereby storing the mechanical energy of the pendulum swinging in two directions.

Based on the above structure, as long as the user makes the training equipment move, the mechanical energy in the energy storage structure will increase to provide power. Even in an environment where power is not available, the sports equipment can still rely on the mechanical energy in the energy storage structure to provide the user Send feedback so that the user can complete the training.

The energy storage structure can be, but is not limited to, a barrel. The input end 3041 of the barrel is connected to the first ratchet drive, and the output end 3042 of the barrel is connected to the power output device. Among them, the transmission connection can be transmitted through a transmission gear 3044.

In addition, the input end and the output end are both gears, and the barrel further includes a mainspring 3043; one end of the mainspring is fixedly connected to the input end, and the other end of the mainspring is fixedly connected to the output end.

Further, the barrel further includes a third pawl 3045 and a fourth pawl 3046; one end of the third pawl is fixed, and the other end abuts in any tooth groove of the input end gear; one end of the fourth pawl is fixed, The other end abuts in any tooth groove of the output gear.

Since the mainspring is constantly tightened, in order to prevent the mechanical energy stored in the mainspring from being output from the input end gear, a third pawl is provided at the input end. Here, the rotation direction of the input gear of the winding spring is expressed as forward rotation. Due to the presence of the third pawl, the input gear will not reverse and the mechanical energy in the spring can only be output from the output gear. The fourth pawl also prevents the output gear from rotating in a direction opposite to the preset rotation direction.

It should be noted that the barrel further includes a torque limiter 3047 provided on the outer side of the barrel. Since the mainspring has a certain limit, after the torque limiter is set on the outside of the mainspring, when the mainspring is wound beyond the torque of the torque limiter, the torque limiter will slip, and the mainspring will not continue to be wound at this time, thus avoiding the The strip broke.

The power output structure of this embodiment may include a transmission device, a power output gear 3051, a brake 3052, and at least one electromagnetic clutch 3053; the transmission device is connected to the output end in transmission, the power output gear is connected in transmission to the transmission device, and the brake and each electromagnetic clutch are fixed in PTO gear on the output shaft. Among them, the speed change device, the brake, and the electromagnetic clutch are the prior art, which will not be repeated here.

In addition, the driving device can also be a motor and the above-mentioned power output structure. The motor can be a speed-regulating motor, a servo motor, or a stepping motor.

In addition, the speed change device and the power output structure can be connected with the controller to control the rotation speed of the power output gear of the power output device, the working state of the brake and the electromagnetic clutch.

Among them, the force measurement sensor may be a pressure sensor or an acceleration sensor. After the measured signal is sent to the controller, the controller processes the signal to obtain the punching force and punching speed of the user. In addition, a force measurement sensor can be set on the arm to get the user's defense.

In addition, a display can be set on the support, and the display can be connected to the controller to receive the user's punching power, punching speed and defense status obtained by the controller through the data measured by the sensors. The above-mentioned data can also be sent to the server through a wireless data transmission device or a wired data transmission device, and the user can obtain the data from the server through an application program of a mobile terminal, such as a mobile phone or a tablet, to learn the training situation. Among them, the wireless transmission device may be WIFI, and the wired data transmission device may be an optical fiber and a terminal box required for optical fiber communication.

In addition to controlling the arm expansion and contraction according to the human body position signal detected by the human body position sensor, the arm attack plan can also be customized through the application, such as attack time, attack speed, attack frequency, etc.

The base can be fixed on the ground by a vacuum suction cup or counterweight or screws. The bracket is fixed on the base, and the bracket is vertical to the ground. The first support rod of the device and the second support rod at a certain angle with the ground are formed, and the training equipment body can be suspended on the second support rod through a suspension chain.

Or fine sand, the inner liner can be made of hard silicone that is not easily deformed.

Example two

In this embodiment, two specific and one specific pop-up bending devices are used as an example to describe the combat training equipment.

Referring to Figure 8, a specific structure of the pop-up bending device includes:

The first torsion spring 606 and the cable 605;

Both ends of the first torsion spring 606 are fixed on the inner surface of the arm 4;

One end of the pull wire 605 is connected to the inner liner 2, and the other end is connected to an end of the first torsion spring 606 away from the first elastic member 603;

When the arm 4 is not extended, the pull wire 605 is in a relaxed state, and the arm 4 is in a straightened state under the fixation of the first torsion spring 606;

When the arm 4 stretches out a preset distance, due to the limited length of the pull wire 605, the pull wire 605 is in a straightened state. At this time, the arm 4 continues to extend, and the pull wire 605 will pull the first An end of a torsion spring 606 away from the first elastic member 603 causes the first torsion spring 606 to rotate and drive the arm 4 to bend.

It should be noted that the bending of the arm is realized by the first torsion spring. Specifically, the process of ejecting and bending the arm is mainly divided into two processes.

Referring to Figure 8, one process is before the arm extends a preset distance. At this time, the pull wire is in a relaxed state, and the arm is in a straightened state under the fixation of the first torsion spring;

Referring to FIG. 9, another process is after the arm extends a preset distance, and at this time, the pull wire is in a tight state. Since the length of the pull wire is limited, the pull wire is in a straightened state, and the arm continues to extend, the pull wire will pull the end of the first torsion spring away from the first elastic member, so that the first The rotation of the torsion spring drives the arm to bend. The arm is in a straightened state under the fixation of the first torsion spring.

It should be noted that when the arm extends a preset distance, the pull wire is in a straight state, that is, the pull wire does not pull the first torsion spring, and the first torsion spring is not deformed. However, if the arm continues to extend forward, due to the limited length of the pull wire, the pull wire pulls the end of the first torsion spring away from the first elastic member, causing the first torsion spring to rotate. When the arm is retracted, as the pulling wire changes from a tight state to a relaxed state, the first torsion spring rotates and returns to the original posture, driving the arm to straighten.

10, another specific structure of the pop-up bending device includes:

The second electromagnet 91, the second torsion spring;

The second electromagnet 91 is connected to the controller;

The second electromagnet 91 is fixed on the inner surface of the preset arm bending position;

The shaft of the second torsion spring is fixed near the second electromagnet 91 on the inner surface of the arm, so that one side of the second torsion spring is twisted and attracted to the second electromagnet 91. The other side of the second torsion spring is fixed on the inner surface of the arm;

The side of the second torsion spring attracted by the second electromagnet 91 is hook-shaped. When the arm is retracted, the hook-shaped side is driven to twist until the hook-shaped side is attracted by the second electromagnetic Iron 91 adsorption.

It should be noted that the bending of the arm is achieved by the second torsion spring. When the second electromagnet is de-energized, one side 922 of the second torsion spring attached to the second electromagnet is twisted under the elastic force of the second torsion spring. Until it is close to the inner surface of the arm.
