Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, specifically to a simulated soccer intelligent teaching robot. Background Technology

[0002] Football is a sport that not only provides physical exercise but also enhances teamwork, which is why it is so popular. Football shooting instruction is one of the basic courses in football teaching and training. Football targets are a type of sports equipment used by football practitioners to practice shooting and improve shooting accuracy. With the improvement of teaching equipment, robotic teaching aids have gradually replaced traditional football targets.

[0003] However, in football shooting training, the robot teaching aids used to intercept the ball are usually fixed in form. When players are shooting on the sidelines or moving to shoot during a match, the opposing goalkeeper will make different actions after defending or making a save. During training, players can only practice shooting and follow-up shots against a single type of robot goalkeeper. Goalkeepers cannot conduct targeted follow-up shot training based on different positions and different types of robot teaching aids, which affects the quality of training. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Therefore, the purpose of this invention is to provide a simulated intelligent soccer teaching robot to replace the traditional goalkeeping robot teaching aids used by athletes during moving shot or rebound shot training. This avoids the problem that athletes can only perform moving shot or rebound shot training with a single type of goalkeeping robot, which leads to low training quality.

[0006] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0015] The drive assembly includes a threaded rod mounted on the horizontal plate of the side wall of the vertical plate and a first drive motor mounted on the horizontal plate with its output end connected to the side wall of the threaded rod. The first drive motor is electrically connected to the control system.

[0016] The side wall of the main body is provided with a connecting block that extends out of the first limiting groove and is threadedly connected to the threaded rod.

[0017] As a preferred embodiment of the simulated soccer intelligent teaching robot teaching aid described in this invention, the defensive mechanism further includes a linkage component that drives the two second defensive bars to move closer or further apart when the main body moves up and down along the first limiting slide groove.

[0018] As a preferred embodiment of the simulated soccer intelligent teaching robot teaching aid described in this invention, the bottom of the main body is provided with a first hinge seat.

[0019] The linkage assembly includes a slide rail located on the side wall of the vertical plate, two limiting rods with one end slidably connected to the slide rail and having a second hinge seat at the top, and two hinge rods with one end hinged to the first hinge seat and the other end hinged to the corresponding second hinge seat.

[0020] As a preferred embodiment of the simulated soccer intelligent teaching robot teaching aid described in this invention, the base is provided with an installation groove inside, and the inner wall of the installation groove is provided with a second limiting slide groove.

[0021] The drive mechanism includes a first reciprocating lead screw located in the mounting slot and a second drive motor installed on the side wall of the base and whose output end is connected to the side wall of the reciprocating lead screw.

[0022] The bottom of the connecting seat is threaded to the first reciprocating lead screw and the side wall has a limiting protrusion extending into the second limiting groove.

[0023] As a preferred embodiment of the simulated soccer intelligent teaching robot teaching aid described in this invention, the random triggering mechanism includes a housing located on one side of the base, a random triggering component located inside the housing that triggers the defensive mechanism to randomly switch between the first state, the second state, and the third state when in operation, and a transmission component that is connected to the driving mechanism and drives the random triggering component to work when in operation.

[0024] As a preferred embodiment of the simulated soccer intelligent teaching robot teaching aid described in this invention, the box body is provided with a partition.

[0025] The random triggering component includes a fan installed on the side wall of the partition, a turntable connected to the fan shaft on the side wall, a plurality of first signal transmitters evenly distributed on the side wall of the turntable, a plurality of second signal transmitters evenly distributed on the side wall of the turntable and interspersed with the plurality of first signal transmitters, and a signal receiver located inside the housing and electrically connected to the control system, wherein a gap is left between adjacent first signal transmitters and second signal transmitters.

[0026] As a preferred embodiment of the simulated soccer intelligent teaching robot teaching aid described in this invention, the output end of the second drive motor is connected to a first pulley on the other side, which is connected to the first reciprocating lead screw, via a rotating shaft;

[0027] The transmission assembly includes a second reciprocating screw connected at one end to the side wall of the partition away from the fan, a movable plate slidably installed in the housing and threaded onto the second reciprocating screw, and a second pulley connected to the other end of the second reciprocating screw via a rotating shaft and connected to the first pulley via a belt.

[0028] The partition wall is provided with a first vent pipe having a one-way valve on the side wall;

[0029] Ventilation holes are provided on both sides of the box body;

[0030] The top of the housing is provided with a second vent pipe with a one-way valve on the side wall near one end of the movable plate.

[0031] Compared with the prior art, the beneficial effects of this invention are that the simulated soccer intelligent teaching robot, through the drive mechanism, drives the defensive mechanism to move back and forth on the base, while simultaneously activating the random trigger mechanism. When the random trigger mechanism is working, it triggers the moving defensive mechanism to randomly switch between the first, second, and third states. This allows athletes to shoot based on the random defensive actions taken by the defensive mechanism during moving shots or follow-up shots, replacing the traditional goalkeeping robot teaching aids used by athletes in moving shot or follow-up shot soccer training. This avoids the problem that athletes can only train moving shots or follow-up shots against a single type of goalkeeping robot, resulting in low training quality. Attached Figure Description

[0043] Secondly, the present invention is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention.

[0044] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0045] This invention provides a simulated soccer intelligent teaching robot, which replaces the traditional goalkeeping robot teaching aid used by athletes during moving shot or rebound shot training. It avoids the problem that athletes can only practice moving shot or rebound shot with a single type of goalkeeping robot, resulting in low training quality.

[0046] Figures 1-8 The diagram shown is a structural schematic of a simulated soccer intelligent teaching robot of the present invention. Please refer to [link / reference]. Figures 1-8This paper provides a detailed introduction to this type of simulated soccer intelligent teaching robot.

[0047] Example 1

[0048] refer to Figures 1-8 This invention discloses a simulated soccer intelligent teaching robot, the main body of which includes a base 100, a defensive mechanism 200, a driving mechanism 300, and a random triggering mechanism 400.

[0049] refer to Figures 1-4 The base 100 is used to facilitate the installation of the defensive mechanism 200 and the drive mechanism 300. The base 100 can be detached and placed in front of the goal, which facilitates the training of athletes to move and shoot or to shoot on the rebound in front of the goal.

[0050] refer to Figures 1-4 The defensive mechanism 200 is used to intercept the football shot by the athlete by making different defensive actions, so as to facilitate the athlete to practice moving shots or rebound shots according to different defensive actions. The defensive mechanism 200 is movably installed on the base 100. The defensive mechanism 200 has a first state simulating the goalkeeper standing normally, a second state simulating the goalkeeper crouching, and a third state simulating the goalkeeper jumping. In the first state, the defensive mechanism 200 facilitates the athlete to make targeted moving shots or rebound shots when the goalkeeper is standing normally. In the second state, the defensive mechanism 200 facilitates the athlete to make targeted moving shots or rebound shots when the goalkeeper is crouching. In the third state, the defensive mechanism 200 facilitates the athlete to make targeted moving shots or rebound shots after the goalkeeper jumps.

[0051] refer to Figures 1-5 The drive mechanism 300 is used to drive the defensive mechanism 200 to move back and forth in front of the goal. The drive mechanism 300 is mounted on the base 100 and drives the defensive mechanism 200 to move back and forth on the base 100 when it is working, so as to facilitate the athlete to move and shoot or follow up when the defensive mechanism 200 is in different positions in front of the goal.

[0052] refer to Figures 1-8 The random triggering mechanism 400 is used to trigger the defensive mechanism 200 to randomly switch between the first, second, and third states during operation. The random triggering mechanism 400 is located on one side of the base 100 and is connected to the drive mechanism 300. When the drive mechanism 300 is working, driving the defensive mechanism 200 to move back and forth on the base 100, the random triggering mechanism 400 is driven to start working, so that the defensive mechanism 200 randomly switches between the first, second, and third states. This makes it convenient for athletes to move and shoot or make follow-up shots based on the defensive actions made by the defensive mechanism 200 at different positions during training.

[0053] In this embodiment, the specific usage process is as follows: When athletes need to train for moving shots or follow-up shots, the entire teaching aid is placed in front of the goal. During the training process, the drive mechanism 300 drives the defensive mechanism 200 to move back and forth on the base 100. At the same time, the random trigger mechanism 400 starts working, causing the defensive mechanism 200 to randomly switch between the first state, the second state, and the third state. This allows the defensive mechanism 200 to randomly change its defensive actions in different positions. At this time, the athletes can perform targeted moving shots or follow-up shots based on the defensive actions randomly performed by the defensive mechanism 200 in different positions, thereby improving the training quality.

[0054] Example 2

[0055] Based on Example 1, and referring to Figures 6-7 The defensive mechanism 200 includes a connecting seat 210, a defensive component 220 movably mounted on the connecting seat 210, and a drive component 230 mounted on the connecting seat 210 and connected to the defensive component 220 in a transmission manner. The connecting seat 210 is used to facilitate the installation of the defensive component 220, the drive component 230, and the linkage component 240. The defensive component 220 is used to perform different defensive actions to intercept the football shot by the athlete. The drive component 230 is used to drive the defensive component 220 to switch between different defensive actions when working.

[0056] In this embodiment, reference Figures 6-7 The defensive component 220 includes a main body 220a, first defensive bars 220b located on both sides of the main body 220a, and second defensive bars 220c hinged to the bottom ends of the main body 220a. The main body 220a is used to simulate the goalkeeper's body to intercept the football, the first defensive bars 220b are used to simulate the goalkeeper's arms to intercept the football, and the second defensive bars 220c are used to simulate the goalkeeper's legs to intercept the football.

[0057] In this embodiment, the first defensive bar 220b and the second defensive bar 220c are telescopic bars, which facilitates the adjustment of length for targeted training when simulating goalkeepers with different arm and leg lengths as needed.

[0058] In this embodiment, reference Figures 6-7 The top side of the connecting seat 210 is provided with a vertical plate 210b with a first limiting groove 210b-1 on the side wall. The vertical plate 210b is used to facilitate the installation of the drive assembly 230. The first limiting groove 210b-1 is used to facilitate the connection between the connecting block 220a-1 and the threaded rod 230a. After the connecting block 220a-1 is limited, when the threaded rod 230a rotates, it drives the connecting block 220a-1 and the main body 220a to move along the first limiting groove 210b-1.

[0059] refer to Figures 6-7 The drive assembly 230 includes a threaded rod 230a mounted on the horizontal plate of the side wall of the vertical plate 210b and a first drive motor 230b mounted on the horizontal plate with its output end connected to the side wall of the threaded rod 230a. The first drive motor 230b is electrically connected to the control system. The threaded rod 230a is used to drive the main body 220a to move up and down along the first limit slide groove 210b-1 when it rotates. The first drive motor 230b is used to rotate forward or reverse after receiving a signal from the control system, thereby driving the threaded rod 230a to rotate forward or reverse.

[0060] refer to Figures 6-7 The side wall of the main body 220a is provided with a connecting block 220a-1 extending out a first limiting slide groove 210b-1 and threadedly connected to the threaded rod 230a. After being threadedly connected to the threaded rod 230a, the connecting block 220a-1 and the main body 220a are driven to move up and down under the limiting action of the first limiting slide groove 210b-1 when the threaded rod 230a rotates.

[0061] In this embodiment, reference Figures 6-7 The defensive mechanism 200 also includes a linkage component 240 that drives the two second defensive bars 220c to move closer or further apart when the main body 220a moves up and down along the first limiting slide 210b-1. This component is used to make the two second defensive bars 220c move further apart when the main body 220a moves down along the first limiting slide 210b-1, thereby simulating the defensive action of a goalkeeper squatting with his legs open.

[0062] In this embodiment, reference Figures 6-7 The bottom of the main body 220a is provided with a first hinge seat 220a-2, which is used to hinge one end of the hinge rod 240c.

[0063] refer to Figures 6-7 The linkage component 240 includes a slide rail 240a located on the side wall of the vertical plate 210b, two limiting rods 240b with one end slidably connected to the slide rail 240a and having a second hinge seat at the top, and two hinge rods 240c with one end hinged to the first hinge seat 220a-2 and the other end hinged to the corresponding second hinge seat. The slide rail 240a is used to facilitate the linear movement of the limiting rods 240b. The limiting rods 240b are used to limit the second guard rods 220c, so that when the two limiting rods 240b move away from each other, the two second guard rods 220c are driven to open. The hinge seat is used to connect the main body 220a and the limiting rods 240b, so that when the main body 220a is raised or lowered, under the connecting action of the hinge rods 240c, the two limiting rods 240b are driven to move closer or further away from each other, thereby causing the two second guard rods 220c to move closer or further away from each other.

[0064] In this embodiment, the specific workflow is as follows: When the first drive motor 230b does not receive a signal from the control system, the first drive motor 230b does not rotate, and thus the threaded rod 230a does not rotate. (Refer to...) Figure 1 The main body 220a remains stationary, thus the entire defensive assembly 220 is in a state simulating a goalkeeper standing in defense. When the first drive motor 230b receives the forward rotation signal from the control system, the first drive motor 230b performs a forward rotation and then a reset operation, driving the threaded rod 230a to rotate forward, thereby driving the connecting block 220a-1 and the main body 220a to descend along the first limit slide groove 210b-1. During the descent of the main body 220a, the hinge rod 240c drives the two limit rods 240b to move away from each other, thereby driving the two second defensive rods 220c to move away from each other. (Reference) Figure 2 After the entire defensive assembly 220 switches to the state simulating a goalkeeper crouching with legs open in defense, it returns to its original state. When the first drive motor 230b receives a reverse signal from the control system, it performs a reverse and reset operation, driving the threaded rod 230a to rotate in the opposite direction. This drives the connecting block 220a-1 and the main body 220a to rise along the first limit slide groove 210b-1. (Reference) Figure 3 At this point, the entire defensive component 220 returns to its original state after switching to the state of simulating a goalkeeper jumping to defend, thus making it easier for athletes to move and shoot or make follow-up shots according to the different defensive states of the defensive component 220.

[0065] Example 3

[0066] Based on Example 2, and referring to Figures 1-5 The base 100 has an internal mounting groove 110 for easy installation of the first reciprocating screw 310. The inner wall of the mounting groove 110 has a second limiting slide groove 110a for connecting with the limiting protrusion 210a to limit the connecting seat 210, so that when the first reciprocating screw 310 rotates, the connecting seat 210 moves back and forth along the second limiting slide groove 110a under the limiting action.

[0067] refer to Figure 5 The drive mechanism 300 includes a first reciprocating lead screw 310 located in the mounting groove 110 and a second drive motor 320 mounted on the side wall of the base 100 and whose output end is connected to the side wall of the reciprocating lead screw. When the first reciprocating lead screw 310 is rotated, it drives the connecting seat 210 to reciprocate along the second limiting slide groove 110a. When the second drive motor 320 is working, it drives the first reciprocating lead screw 310 to rotate.

[0068] refer to Figures 6-7The bottom of the connecting seat 210 is threadedly connected to the first reciprocating lead screw 310 and the side wall has a limiting protrusion 210a extending into the second limiting slide groove 110a. When the first reciprocating lead screw 310 rotates, the connecting seat 210 moves reciprocally along the second limiting slide groove 110a under the limiting action of the limiting protrusion 210a and the second limiting slide groove 110a.

[0069] In this embodiment, the specific workflow is as follows: When the second drive motor 320 is working, it drives the second reciprocating screw 430a to rotate. When the second reciprocating screw 430a rotates, it drives the connecting seat 210 to move back and forth along the second limiting slide groove 110a, thereby driving the entire defensive mechanism 200 to move back and forth along the second limiting slide groove 110a. This facilitates the defensive mechanism 200 to make defensive actions at different positions in front of the goal, thereby facilitating athletes to conduct targeted moving shots or follow-up shots training based on the defensive actions randomly made by the defensive mechanism 200 at different positions.

[0070] Example 4

[0071] Based on Example 3, and referring to Figure 1 and Figure 8 The random triggering mechanism 400 includes a housing 410 located on one side of the base 100, a random triggering component 420 located inside the housing 410 and randomly switching between the first, second, and third states of the defense mechanism 200 during operation, and a transmission component 430 that is connected to the drive mechanism 300 and drives the random triggering component 420 during operation. The housing 410 is used to facilitate the installation of the random triggering component 420 and the transmission component 430. The random triggering component 420 is used to drive the defense mechanism 200 to randomly switch between the first, second, and third states during operation. The transmission component 430 is used to drive the random triggering component 420 to operate while the drive mechanism 300 is working and driving the defense mechanism 200 to reciprocate along the second limit slide groove 110a.

[0072] In this embodiment, reference Figure 8 The box 410 is provided with a partition 410a inside, which is used to separate the inside of the box 410.

[0073] refer to Figure 8The random triggering component 420 includes a fan 420a mounted on the side wall of the partition 410a, a turntable 420b connected to the shaft of the fan 420a on the side wall, a plurality of first signal transmitters 420c evenly distributed on the side wall of the turntable 420b, a plurality of second signal transmitters 420d evenly distributed on the side wall of the turntable 420b and interspersed with the plurality of first signal transmitters 420c, and a signal receiver 420e located inside the housing 410 and electrically connected to the control system. The fan 420a is used to drive the turntable 420b to rotate when it rotates. The turntable 420b is used to facilitate the installation of the plurality of first signal transmitters 420c and the plurality of second signal transmitters 420d. The first signal transmitters 420c are used to send a signal for the first drive motor 230b to return to its original position after one forward rotation. The second signal transmitters 420d are used to send a signal for the first drive motor 230b to return to its original position after one forward rotation. The signal receiver 420e transmits the received signal from the first signal transmitter 420c or the second signal transmitter 420d to the control system. Then, the control system sends a signal to the first drive motor 230b to complete one forward rotation and then return to its original position, or to return to its original position after one reverse rotation. This causes the defense component 220 to switch to the second state and then return to its original position, or to switch to the third state and then return to its original position. There is a gap between the adjacent first signal transmitter 420c and second signal transmitter 420d so that when the turntable 420b is stationary, the signal receiver 420e will not receive the signals emitted by the first signal transmitter 420c and the second signal transmitter 420d. At this time, the first drive motor 230b remains stationary, so that the defense mechanism 200 remains in the first state.

[0074] In this embodiment, reference Figure 5 The output end of the second drive motor 320 is connected to a first pulley 320a connected to the first reciprocating lead screw 310 on the other side via a rotating shaft. When the second drive motor 320 rotates and drives it to rotate, it drives the second pulley 430c to rotate.

[0075] refer to Figure 8 The transmission assembly 430 includes a second reciprocating screw 430a connected at one end to the side wall of the partition 410a away from the fan 420a, a movable plate 430b slidably installed inside the housing 410 and threaded onto the second reciprocating screw 430a, and a second pulley 430c connected to the other end of the second reciprocating screw 430a via a rotating shaft and connected to the first pulley 320a via a belt. When the second reciprocating screw 430a rotates, it drives the movable plate 430b to move back and forth inside the housing 410, thereby repeatedly compressing the air on the right side of the partition 410a inside the housing 410. When the second pulley 430c rotates, it drives the second threaded rod 230a to rotate.

[0076] refer to Figure 8The partition 410a has a first vent pipe 410a-1 with a one-way valve on its side wall. When the moving plate 430b moves to the side adjacent to the partition 410a, the compressed air on the right side of the partition 410a inside the box 410 is introduced to the left side of the partition 410a inside the box 410. This causes the fan 420a to rotate once randomly, which in turn drives the turntable 420b to rotate once randomly. After the fan 420a and the turntable 420b come to a stop, the signal receiver 420e randomly receives the first signal transmission. If the signal emitted by the transmitter 420c and the second signal transmitter 420d is not received, the one-way valve on the first vent pipe 410a-1 is used to prevent air from being drawn from the left side of the partition 410a inside the housing 410 when the moving plate 430b moves away from the partition 410a. This causes the fan 420a to reverse, making it impossible for the fan 420a to stop between forward and reverse rotation. The signal receiver 420e will never receive the signal, which in turn prevents the defense mechanism 200 from switching actions.

[0077] refer to Figure 8 Ventilation holes 410b are provided on both sides of the box 410 to allow air circulation between the left side space of the internal partition 410a and the right side space of the movable plate 430b and the outside.

[0078] refer to Figure 8 The top of the housing 410 is provided with a second vent pipe 410c with a one-way valve on the side wall. When the moving plate 430b moves away from the partition 410a, air is drawn from the outside through the second vent pipe 410c to replenish the space between the partition 410a and the moving plate 430b. The one-way valve on the second vent pipe 410c is used to prevent the air between the partition 410a and the moving plate 430b from being discharged through the second vent pipe 410c when the moving plate 430b moves close to the partition 410a, so that the power generated when the air is discharged through the first air guide pipe cannot drive the fan 420a to rotate.

[0079] In this embodiment, the specific workflow is as follows: When the second drive motor 320 rotates and drives the first pulley 320a to rotate, the second pulley 430c drives the second reciprocating screw 430a to rotate. When the second reciprocating screw 430a rotates, it drives the moving plate 430b to reciprocate on the right side of the partition 410a inside the housing 410. When the moving plate 430b moves towards the partition 410a, the air between the partition 410a and the moving plate 430b is blown through the first vent pipe 410a-1 into the space on the left side of the partition 410a inside the housing 410, thereby causing the fan 420a to rotate once and then randomly stop, thereby causing the turntable 420b to rotate once and then stop. When the turntable 420b stops, the signal receiver 420e randomly... Upon receiving a signal from the first signal transmitter 420c or the second signal transmitter 420d, or if no signal is received, the signal transmitter will transmit the randomly received signal from the first signal transmitter 420c or the second signal transmitter 420d to the control system, or will randomly not transmit a signal. Then, the control system will send a signal to the first drive motor 230b to perform a forward rotation followed by a return to normal or a reverse rotation followed by a return to normal, or will not send a signal. This will cause the defensive mechanism 200 to randomly switch to the defensive action in the second or third state, or remain in the first state. Consequently, the defensive mechanism 200 will randomly perform defensive actions at different positions in front of the goal, which will facilitate athletes to conduct targeted moving shot or follow-up shot training based on the defensive actions of the defensive mechanism 200 in different positions and with random changes.

[0080] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
