Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and in particular to a bow and arrow device for safe training and a using method thereof. Background Art

[0002] Archery is a sport with a long history in China. The operator needs to put the arrow on the bowstring of the bow and shoot the arrow by pulling the bowstring. However, since arrows shot at high speeds are dangerous, there are certain risks whether indoors or outdoors, and it is difficult to find a suitable place for archery. As a result, archery can only be performed in specific venues, which affects the popularity of archery.

[0003] A common risk in archery comes from the piercing of living things by bows and arrows, especially for unskilled people, who may miss the target during archery, causing the flying arrows to hit people or objects that are not in sight or within the target range, thus causing damage. In addition, existing bows and arrows rely on frequent shooting to adjust and become proficient during practice. However, archery itself requires a lot of physical strength, and a small amount of shooting in a short period of time can only be used as entertainment, which has limited impact on improving archery skills. Long-term shooting can easily lead to problems such as lack of physical strength or stretching of arm muscles. Summary of the invention

[0004] In view of the prior art, the purpose of the present invention is to provide a bow and arrow device that can assist in safe shooting training, which can not only improve the safety during archery, but also assist students to wait for shooting after drawing the bow, thereby reducing physical exertion and increasing the number of shooting times.

[0005] In order to achieve the above objectives, the technical solution adopted by the present invention is: a bow and arrow device used for safety training, including a bow body and an arrow, the bow body including a bow cup, a bow arm and a bowstring, the bow arm being hinged on the bow cup, and an electric push rod being also provided on the bow cup, one end of the electric push rod being hinged on the bow cup, and the other end of the electric push rod being hinged on the bow arm, forming a triangular support structure with the bow cup and the bow arm, a training auxiliary system being also provided on the bow cup, the training auxiliary system electrically connecting the electric push rod and an arrow locking device installed at the bow cup, the training auxiliary system being used to observe the safety situation of the target position in front and near the target position, and feeding back the acquired information to the control center, and issuing commands through the control center to control the actions of the electric push rod and the arrow locking device.

[0006] As a further configuration of the above scheme, the bow cup includes a hand grip, an arrow resting portion and a sight piece, and a display screen area electrically connected to the training auxiliary system is also provided on the bow cup above the sight piece.

[0007] As a further configuration of the above scheme, the training assistance system includes a distance measuring sensor, a laser emission component, a height sensor and a machine vision lens, which are used to detect the target distance, the bow and arrow height and the safety situation within the range, and display them on the display screen area.

[0008] As a further configuration of the above scheme, the arrow locking device includes a power piece, at least one group of friction wheels and a control button, the power piece is used to drive the friction wheels to move relatively closer or farther away, and the control button is used to trigger the power piece.

[0009] As a further configuration of the above scheme, the friction wheel is provided with a one-way ratchet structure or a one-way bearing to limit the arrow from flying out, and a friction clamping groove is also provided on the circumference of the friction wheel, and the diameter of the friction clamping groove is smaller than the diameter of the arrow.

[0010] As a further configuration of the above scheme, an external power supply device is also included. An electric conductor is arranged between the external power supply device and the bow body. The external power supply device is used to provide electric energy for the training auxiliary system, the arrow locking device and the electric push rod.

[0011] A method for using a bow and arrow device for safety training, characterized by comprising the following steps:

[0012] S1, take out the bow body in the stored state, at which time the electric push rod is in the retracted state, and then turn on the training auxiliary system to control the electric push rod to extend;

[0013] S2. The bow arm is swung relative to the bow cup by the electric push rod, and the electric push rod cooperates to form a triangular support. The extension length of the electric push rod is controlled by the training auxiliary system, and the adjustment of the bowstring tension pounds is input into the training auxiliary system to meet the shooting needs of each student.

[0014] S3. If the student is not sure about the poundage that he or she is comfortable with, the training auxiliary system can adjust the length of the electric push rod according to the student's bow drawing state when drawing the bow. That is, the student can draw the bow according to his or her own strength, and the training auxiliary system can adaptively adjust the length of the electric push rod according to the bow drawing state, so that after multiple adjustments, the student's habits can be met.

[0015] S4. After the adjustment is completed, the trainee lifts the bow normally and puts the arrow into the nocking part from the side. At this time, the sensor of the training auxiliary system senses that the arrow is nocking the bow and issues a command to drive the friction wheel to relatively approach and clamp the arrow through the power part;

[0016] S5. When the trainee draws the bow, the training assistance system observes the front of the bow and calculates the arrow's landing point based on the distance to the target, the poundage of the bow and the angle of the arrow. The program's built-in algorithm analyzes the range of the landing point and provides feedback based on whether there are safety issues within the circled range.

[0017] S6. Before the calculation is completed, the background of the display area turns yellow. At this time, the arrow locking device maintains the locking force. The user releases the grip on the arrow, and the arrow locking device can still prevent the arrow from flying out;

[0018] S7. When the calculation is completed, the display screen will show a green prompt. At this time, the user needs to hold the tail of the arrow to restore the bow state, and release the arrow lock device by pressing the control button, and then release the arrow to shoot normally;

[0019] S8. In the S7 state, if after the calculation is completed, the training assistance system detects a sudden intrusion safety risk, it will bypass the trainee and quickly issue a command to either retract the electric push rod, thereby loosening the bow arm and reducing or eliminating the bowstring tension, or quickly reset the arrow lock device to resume clamping the arrow. The arrow lock device fails to clamp the arrow, and the arrow will fly out and can be interfered with as long as it touches it;

[0020] S9. After the shooting is completed, the trainees can also quickly obtain information about the shooting location through the training assistance system, and analyze and adjust the strategy to assist in training based on the information.

[0021] Beneficial effect: The present invention provides a bow and arrow shooting device that can help students continue to train safely. Compared with ordinary bow and arrow structures, the invention of this embodiment adds an analysis assistance system based on machine vision to the bow and arrow. By quickly calculating and analyzing the possible trajectory and landing point range of the arrow after being shot through the self-checking position of the bow and arrow, the target shooting position and the angle of the arrow, the user can shoot normally only after eliminating the risks within the landing point range and the safety range. Otherwise, various means are used to restrict the archery. In addition, the restrictive structural setting can also maintain the arrow in the full bow state, reducing the physical exertion of continuous bow drawing, thereby ensuring the safe shooting experience and training effect of the bow and arrow.

DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0027] like Figure 1-3 A bow and arrow device for safety training shown in the figure includes a bow body 1 and an arrow 2. The bow body 1 includes a bow cup 11, a bow arm 12 and a bowstring 13. The bow arm 12 is hinged on the bow cup 11, and an electric push rod 24 is also provided on the bow cup 11. One end of the electric push rod 24 is hinged to the bow cup 11, and the other end is hinged to the bow arm 12, forming a triangular support structure with the bow cup 11 and the bow arm 12. The bowstring 13 is connected to the ends of the bow arms 12 at both ends of the bow and arrow.

[0028] In the present invention, a training auxiliary system 3 is also provided on the bow cup 11, and the training auxiliary system 3 is electrically connected to the electric push rod 24 and the arrow locking device 4 installed at the bow cup 11. As mentioned above, the bow and arrow of this embodiment is provided with a training auxiliary system 3, which is electrically connected to the electric push rod 24 and the arrow locking device 4. Referring to the above-mentioned settings, the arrow locking device 4 of this embodiment can clamp and lock the arrow 2 before and during shooting, firstly, it can prevent the arrow 2 from being shot out of the hand in an unsafe state, and secondly, it can restrict and clamp the arrow 2 before it is shot out of the hand but not out of the bow and arrow, thereby destroying its normal flight action of shooting;

[0029] Furthermore, the training assistance system 3 of the present invention adopts a module device of machine vision technology, and cooperates with a built-in program to collect site safety information within a circle around the target position in front and the target position. Referring to the machine vision technology function of the prior art, the acquired information is fed back to the control center, and the control center analyzes the information on the image. After confirming that there are no safety issues within the visible range of the shooting range, and that there will basically be no accidental intrusion of personnel within the extended line of sight, the control center can issue a command to control the electric push rod 24 and the arrow locking device 4 to release the restriction action. Once the above-mentioned dangerous safety problem occurs, a control command is issued to allow the electric push rod 24 to retract and the arrow locking device 4 to quickly reset to restrict and lock the arrow 2 to prevent it from flying out.

[0030] As a further configuration of the above scheme, the bow cup 11 includes a hand grip 14, an arrow rest 15 and a sight 16. A display screen area 17 electrically connected to the training assistance system 3 is also provided on the bow cup 11 above the sight 16. The training assistance system 3 includes a range sensor, a laser emission component, a height sensor and a machine vision lens for detecting the target distance, the bow height and the safety situation within the range, and displaying them on the display screen area 17. Furthermore, in the embodiment of the present invention, the display screen area 17 can be used to display the machine vision technology obtained on the training assistance system 3. Various useful parameters can be displayed, such as the distance to the target, the height of the bow and arrow from the standing ground, etc., and further, the background light of the display area 17 can be displayed to allow the user to quickly know the safety level of the training auxiliary system 3 for the shooting situation. For example, when the background is yellow, it means that the current state is not shootable, that is, it is necessary to wait for the arrow 2 to be shot, and green means that the current state is shootable. When a red background prompt appears, it indicates that there is a major safety situation within the range, such as someone breaking into the vicinity of the target. At this time, you must stay highly focused to avoid the arrow 2 from accidentally flying out, which may cause safety problems.

[0031] As a further configuration of the above scheme, the arrow locking device 4 includes a power member 41, at least one group of friction wheels 42 and a control button 43, wherein the power member 41 is used to drive the friction wheels 42 to move relatively closer or farther away, and the control button 43 is used to trigger the power member 41, and a one-way ratchet structure or a one-way bearing is provided on the friction wheel 42 to limit the arrow 2 from flying out, and a friction clamping groove 44 is also provided on the circumference of the friction wheel 42, and the diameter of the friction clamping groove 44 is smaller than the diameter size of the arrow 2. As shown in the above structure, the arrow locking device 4 of this embodiment acts on The arrow 2 can be locked. The purpose of setting the one-way structure is that when the bow is drawn, the arrow 2 is pulled back, the friction wheel 42 has a small one-way rolling friction, and the friction wheel 42 is locked in the shooting direction of the arrow 2, which can prevent the arrow 2 from flying out, and the arrow locking device 4 can also be used to lock the arrow 2. When the locking force is greater than the reaction force of the bowstring 13, when the bow of this embodiment is in use, the user can also reduce the holding force after drawing the bow in the full bow state, thereby reducing the physical exertion during training and allowing the trainees to maintain their physical strength for multiple shooting.

[0032] Furthermore, as in the above-mentioned setting, the power member 41 includes a push rod for separating or bringing at least two friction wheels 42 closer together. The push rod is electrically controlled and quickly extends or retracts when receiving a signal, thereby enabling the approaching friction wheels 42 to quickly clamp the arrow 2 or release the clamping of the arrow 2.

[0033] As a further configuration of the above scheme, an external power supply device 8 is also included. An electric conductor 81 is provided between the external power supply device 8 and the bow body 1. The external power supply device 8 is used to provide electric energy to the training auxiliary system 3, the arrow locking device 4 and the electric push rod 24.

[0034] A method for performing bow and arrow shooting practice using the bow and arrow device for safety training includes the following steps:

[0035] S1, take out the bow body 1 in the storage state, at which time the electric push rod 24 is in the retracted state, and then turn on the training auxiliary system 3 to control the electric push rod 24 to extend. This setting can keep the bow in the storage state, which can not only reduce the volume, but also reduce the non-use wear caused by the tension of the bow when not in use;

[0036] S2. The bow arm 12 is swung relative to the bow cup 11 by the electric push rod 24. The electric push rod 24 cooperates to form a triangular support, and the extension length of the electric push rod 24 is controlled by the training auxiliary system 3. The adjustment of the tension of the bow string 13 is input into the training auxiliary system 3 to meet the shooting needs of each student. Each person has different shooting needs according to their height, arm span, strength, usage habits, etc. Therefore, adapting to their own needs can not only improve the shooting experience, but also improve the training effect;

[0037] S3, when the student is not clear about the poundage that he / she is suitable for, the training auxiliary system 3 can adjust the length of the electric push rod 24 according to the student's bow drawing state when drawing the bow, that is, the student can draw the bow according to his / her own strength, and the training auxiliary system 3 can adaptively adjust the length of the electric push rod 24 according to the bow drawing state, so as to meet the student's habit after multiple drawing adjustments. The purpose of this setting is to enter the training auxiliary system 3 multiple bow drawing data into the program to match and calculate the appropriate bow strength for the student;

[0038] S4, after the adjustment is completed, the trainee lifts the bow body 1 normally and puts the arrow 2 into the nocking part 15 from the side. At this time, the sensor of the training auxiliary system 3 senses that the arrow 2 is nocking on the bow, and issues a command to drive the friction wheel 42 to relatively approach and clamp the arrow 2 through the power member 41;

[0039] S5. When the trainee draws the bow, the training auxiliary system 3 observes the front of the bow body 1, and calculates the landing point of the arrow 2 according to the distance to the target position, the poundage of the bow and the angle of the arrow 2, analyzes the range of the landing point through the built-in algorithm of the program, and provides feedback according to whether there is a safety problem within the circled range;

[0040] S6. Before the calculation is completed, the background of the display area 17 is yellow. At this time, the arrow locking device 4 maintains the locking force. The user releases the grip on the arrow 2, and the arrow locking device 4 can still prevent the arrow 2 from flying out;

[0041] S7. When the calculation is completed, the display area 17 shows a green prompt. At this time, the user needs to hold the tail of the arrow 2 to restore the bow state, and release the arrow locking device 4 by pressing the control button 43. Then, release the arrow 2 to shoot normally.

[0042] S8. In the state of S7, if after the calculation is completed, the training auxiliary system 3 detects the safety risk of sudden intrusion, it will bypass the trainee and quickly issue a command to shrink the electric push rod 24, so that the bow arm 12 loosens the bowstring 13 and the tension becomes smaller or disappears, and secondly, quickly reset the arrow locking device 4 to restore the clamping of the arrow 2. The arrow locking device 4 fails to clamp the arrow 2, and the arrow 2 can be interfered with as long as it is touched. It is worth noting that after the safety is determined by the previous calculation, if the last clamping interference before the arrow 2 flies away from the bow body 1 is ineffective, then the risk caused by the sudden intrusion cannot be guaranteed. The present invention can only meet the safety risk protection and avoidance in the instantaneous reaction before and after shooting;

[0043] S9. Furthermore, the training assistance system 3 of the present invention also has an auxiliary function after the shooting is completed. This function can refer to the common training assistance design in the prior art, that is, the trainees can also quickly learn the landing point information of the shooting through the training assistance system 3. The machine vision technology collects the actual flight trajectory and landing point of the bow and arrow in real time, and analyzes the information based on the information, optimizes and adjusts the strategy to cope with the auxiliary training through the built-in program, and further gives the trainees some training suggestions such as the angle of the arrow 2, the adjustment of the shooting crosshair position, etc.

[0044] With reference to the above scheme, the bow and arrow device of the present invention comprises a bow body 1 and an arrow 2, wherein a training auxiliary system 3 is arranged on the bow body 1, and the training auxiliary system 3 can be used to observe and calculate the height of the bow and arrow during archery, the distance to the target position, and the tilt angle of the arrow 2 pre-shot after the bow is fully drawn. The present invention further arranges a supporting electric push rod 24 on the bow cup 11 and the bow arm 12, and the electric push rod 24 is controlled by the control center of the training auxiliary system 3. When there is a person or shooting risk within the target range after the bow is drawn, the control center issues a command to slowly retract the electric push rod 24, so that the bow arm 12 is folded inward, so that the bowstring 13 cannot be tightened, thereby failing to complete the shooting to avoid risks; and when there is no shooting risk, the training auxiliary system 3 calculates according to the program settings to estimate the landing point of the bow and arrow. Before the calculation of the landing point range is completed, the arrow 2 is restricted by the friction wheel 42 of the arrow locking device 4 and cannot be shot. When the calculation is completed and reaches the safety level, the user can release the restriction of the friction wheel 42 by triggering the control button 43. At this time, the arrow 2 can be shot normally. In addition, in order to avoid accidental forced shooting (there are people in the front range, which will be a state of safety risk), after the landing point calculation is completed, once the arrow accidentally breaks into the range, the arrow locking device 4 will be reset instantly, the friction wheel 42 clamps the arrow 2, and the electric push rod 24 shrinks quickly. Firstly, the bowstring 13 reduces the power given to the arrow 2. Secondly, if the arrow 2 has been separated from the bowstring, the friction wheel 42 that reacts quickly and resets will make a final effort to clamp the arrow 2. Even if the clamping cannot be complete, it can interfere with the flight of the arrow 2 to improve safety.

[0045] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention belong to the scope of the present invention and its equivalent technology, the present invention is also intended to include these changes and variations.
