An arrow detection device for a repeating crossbow

Abstract

This invention relates to an arrow detection device for repeating crossbows. Its main function is to detect and sense arrows in repeating crossbows. When a magazine containing multiple arrows is loaded and fired, the device detects and determines the number of arrows in the magazine by observing the falling arrows. This allows the user to clearly understand the number of arrows in the magazine and whether each arrow fires smoothly during the firing process, providing a better shooting operation and user experience. This addresses the shortcomings of conventional repeating crossbows, which cannot clearly indicate the number of arrows in the magazine during firing, nor can they effectively judge and understand the entire process of each arrow falling from the magazine, being loaded, and being fired. This leads to situations where the user is easily placed in a dangerous position when troubleshooting.

Description

Arrow detection device for rapid-fire crossbows An arrow detection device for a repeating crossbow Technical Field

[0001] This invention relates to an arrow detection device for a repeating crossbow, specifically a technology applied to the field of archery. Its main technology is to provide the user with information on the number of arrows in the quiver and the status of the arrow firing process, thereby making the firing process smoother and enabling immediate reaction and handling in case of any issues. Prior Technology

[0002] Archery is now a mainstream sport, testing not only accuracy but also, more importantly, the operator's stability and judgment. Bows and arrows can be basically divided into two types: the hand-drawn bow (commonly known as the crescent bow) and the crossbow (commonly known as the crossbow), which is the subject of this discussion. With the advancement of technology, the crossbow has evolved from the traditional method of setting up each arrow individually to the current use of dedicated quivers for continuous firing. This change has significantly reduced the action of setting up the arrows for the user, allowing the user to maintain a more stable firing frequency and greatly improve shooting accuracy.

[0003] However, the aforementioned crossbow with a quiver design presents another problem in its use: during firing, the user cannot know the number of arrows in the quiver or the condition of each arrow. Furthermore, the quiver obstructs the user's view of the arrows. Therefore, from the moment the arrows are fired until they are released, the user cannot effectively judge their condition and can only determine if an abnormality has occurred by whether an arrow has been fired. For a crossbow, a weapon with immense destructive power, this can easily put the user in a very dangerous situation. Therefore, manufacturers must provide a more convenient way for users to use, observe, and judge the arrows, while prioritizing safety. Summary of the Invention

[0004] The main purpose of this invention is to provide users with a clear understanding of the number of arrows in the quiver and whether each arrow fires smoothly during the shooting process, thus providing a better shooting operation and use. It improves upon conventional technology, where crossbows with quivers and rapid-fire capabilities generally fail to provide users with a clear understanding of the number of arrows in the quiver during shooting, and also fail to effectively judge and understand the entire process of each arrow falling from the quiver, being loaded, and being fired. As a result, when problems occur, users are easily placed in dangerous situations to troubleshoot the problem.

[0005] However, in order to achieve the aforementioned effects and improve upon the deficiencies of conventional methods, this invention provides an arrow detection device and its detection and judgment methods for a repeating crossbow. Firstly, regarding the technical content of the inspection and detection device for a repeating crossbow, it includes: a microcontroller mounted on a bow body, with a built-in processing unit; a sensing component mounted on the bow body and electrically connected to the microcontroller, which senses and detects the number of arrows mounted on the bow body before and after firing, and generates multiple data messages after sensing, which are transmitted back to the microcontroller. The processing unit then calculates the number of arrows based on the multiple data messages; and a display module wirelessly or wiredly electrically connected to the microcontroller. The processing unit calculates the remaining number of arrows, generates a result message, and transmits it to the display module.

[0006] Based on the arrow detection device defined in this invention, its advantages lie in its ability to accurately determine the movement of arrows mounted on the bow by utilizing the sensor components, and to provide relevant data, such as the number of arrows that have not moved or been fired, which is further displayed on the display module. This allows the user to determine the number of arrows remaining at any time without being affected by obstruction from other parts or components on the bow. Importantly, it avoids inspection during the firing or shooting process, thus protecting the user's safety in making judgments. This improves the user's ability to maintain stability during shooting operations and quickly determine the number of arrows remaining. It is evident that this invention is a highly practical and progressive creation, worthy of promotion by the industry and public disclosure to the public. Simple Explanation of the Diagram

[0008] The following specific examples illustrate this invention. Those skilled in the art can easily understand its other advantages and effects from the content disclosed in this specification. This invention can also be implemented or applied through other different specific examples, and the details in this specification can be modified and changed based on different viewpoints and applications. The following implementation methods further illustrate the viewpoints of this invention, but are not intended to limit the scope of this invention in any way.

[0009] Please refer to Figures 1 through 12. This invention discloses an arrow detection device for a repeating crossbow, comprising: a microcontroller 1 mounted on a bow body 10, the microcontroller 1 further having a built-in processing unit 11; a sensing component 2 mounted on the bow body 10 and electrically connected to the microcontroller 1, the sensing component 2 sensing and detecting the number of multiple arrows 20 mounted on the bow body 10 before and after firing, and the sensing component 2 generating multiple data information 21 after sensing and transmitting it back to the microcontroller 1, and the processing unit 11 calculating the number of remaining arrows 20 based on the multiple data information 21; and a display module 3 wirelessly or wiredly electrically connected to the microcontroller 1, the processing unit 11 calculating the number of remaining arrows 20 and generating a result information 12 which is transmitted to the display module 3.

[0010] Furthermore, based on the aforementioned detection device settings, the arrow detection method applied to a repeating crossbow is further explained, the steps of which include: an arrow loading step S1: loading a plurality of arrows 20 onto the bow body 10; an operation start-up step S2: starting the operation of the microcontroller 1 and the sensing component 2 of the bow body 10, the microcontroller 1 and the sensing component 2 being electrically connected to each other; and a counting / detection step S3: the bow body 10 begins the stringing operation, when one bowstring 30 of the bow body 10 is pulled and the arrows 20 are moved, the sensing component 2 can detect / sensor and generate the plurality of data information 21. The complex data information 21 is transmitted back to the microcontroller 1 and calculated by the arithmetic processing unit 11 within the microcontroller 1. The arithmetic processing unit 11 calculates the number of each arrow 20 before and after firing. A review step S4: After the arithmetic processing unit 11 completes the calculation, it generates the result information 12. The result information 12 is transmitted to the display module 3 for display. The display module 3 can be divided into a cocking mode E and a firing mode F. The cocking mode E displays the result information 12 plus the number of times the sensing component 2 senses the arrows. The firing mode F displays the result information 12.

[0011] However, based on the aforementioned detection device and detection method settings, the following further explains the relevant judgment method for the arrow 20 during its movement, which is an arrow judgment method applied to a repeating crossbow. The steps include: an arrow loading step S1: loading a plurality of arrows 20 onto the bow body 10; and an operation start-up step S2: starting the operation of the microcontroller 1 and the sensing component 2 of the bow body 10. The microcontroller 1 and the sensing component 2 are electrically connected to each other, and the microcontroller 1 has a built-in preset data database 13 containing... The system contains preset values ​​for the number of arrows, arrow light sensing, arrow vibration, arrow fall time, weight, magnetic field strength, and any value or multiple data information from an electronic serial number sorting table; a counting / detection step S3: When the bow 10 begins to string itself, and the bowstring 30 of the bow 10 is pulled, causing the arrow 20 to move, the sensing component 2 can detect / sensor and generate the plurality of data information 21 (the content of this plurality of data information 21 mainly refers to any physical changes that the arrow 20 will produce during its movement, or...). The arrow 20 causes relevant physical changes to the sensing component 2, such as vibration, light and shadow, or electronic and electrical changes. The complex data information 21 is transmitted back to the microcontroller 1 and calculated by the arithmetic processing unit 11 in the microcontroller 1. The arithmetic processing unit 11 calculates the number of each arrow 20 before and after firing. A review step (A) S41: When the complex data information 21 is inconsistent with the data in the preset data database 13 (inconsistency means, for example, the preset data database 13 does not contain data for a single arrow), The movement of arrow 20 is set based on displacement, velocity, or acceleration. However, if the movement of arrow 20 is abnormally slow or abnormally fast, the sensing component 2 will detect abnormal data (which is different from the corresponding preset value of arrow vibration in the preset data information library 13, thus determining it to be inconsistent). The microcontroller 1 generates an abnormal information 14 and transmits it to the display module 3. The display module 3 further has an error mode D (as shown in Figure 15). When the abnormal information 14 is transmitted to the display module 3, the display module 3 displays the error mode D (the displayed content can be text or an image).Step 1 (B) S42: When the result of comparing the multiple data information 21 with the data in the preset data information library 13 is consistent (consistency means, for example, the time required for a single arrow 20 to move from the start to before firing is 5 seconds, and the preset value for the arrow falling time in the preset data information library 13 is also 5 seconds, so the two times are consistent), then the calculation is further performed by the arithmetic processing unit 11 in the microcontroller 1. The arithmetic processing unit 11 calculates the number of arrows 20 that have not yet moved (the preset data information library 13 has a preset value for the number of arrows 20, and the arithmetic processing unit 11 uses the preset value for the number of arrows 20 in the preset data information library 13 as a reference for calculation); after the arithmetic processing unit 11 completes the calculation, it generates the result information 12 (the result information 12 does not include the arrows 20 that have already been fired), and the result information 12 is transmitted to the display module 3 for display. The display module 3 can be distinguished as the cocking mode E. (As shown in Figure 16) and the firing mode F (as shown in Figure 17), the winding mode E displays the result information 12 + the number of times the sensing component 2 senses, while the firing mode F displays the result information 12.

[0012] In summary, to further explain other technical features of this invention, before proceeding, the structural components of the bow body 10 are clearly defined. The bow body 10 can be mainly divided into a bow body 101 and an arrow magazine 102. The arrow magazine 102 provides mounting / accommodation for a plurality of arrows 20. The arrow magazine 102 is then assembled to the bow body 101. Each arrow 20 located in the arrow magazine 102 will fall one by one onto an arrow-holding platform 103 of the bow body 101 and be fired by the bowstring 30 of the bow body 101. The connection between the display module 3 and the bow body 10 can be divided into two types. The first type is that the display module 3 is directly mounted on the bow body 10. (In this embodiment, the display module 3 can be a screen 31, see Figure 13). The second type is a separate wireless connection between the display module 3 and the bow body 10 (a base for connecting the display module 3 is provided on the bow body 101), which can be connected wirelessly from a distance, or it can be installed on the bow body 101 and electrically connected to the microcontroller 1 (in this embodiment, the display module 3 can be any of a mobile phone, tablet, computer, or cloud, see Figure 14). Both of these types mainly provide users with the ability to directly view the number of arrows 20 without being obstructed by other parts of the bow body 10, thus improving the safety of inspection.Furthermore, regarding the structural features of the bow body 10 and the technology of the sensing component 2 as defined above, based on the structure of the bow body 101 and the arrow magazine 102, it can be further divided into two types. The first type is where the sensing component 2 is set on the arrow placement platform 103 of the bow body 101 (see Figures 1 to 6). Simply put, when an arrow 20 located in the arrow magazine 102 falls onto the arrow placement platform 103, the sensing component 2 will detect and sense (it can sense the number of arrows 20 in the arrow magazine 102 and transmit it to the processing unit 11 to form an initial arrow quantity value, and sense the process of the arrow 20 falling, and the initial arrow quantity value can be recorded in the preset data information database 13 to form a preset arrow quantity value). After sensing, it will generate multiple data information 21 (for example: detecting that an arrow 20 has fallen on the arrow placement platform 103), and transmit the multiple data information 21 to the microcontroller 1 and use it for operation. The calculation processing unit 11 performs calculations. The direction of the calculation can be calculated by subtracting the aforementioned complex data information 21 (for example, the complex data information 21 is the detection of an arrow 20 landing on the arrow placement platform 103) from the preset value of the number of arrows in the preset data information database 13. Therefore, the calculation method of the calculation processing unit 11 is the preset value of the number of arrows - 1 = the result information 12 (represented by N). However, the display on the display module 3 will have different display methods depending on the stringing mode E and the firing mode F. For example, in the stringing mode E, since the arrow 20 has not been fired, the display on the display module 3 should be N+1 (this value will be equal to the preset value of the number of arrows). In the firing mode F, the display module 3 will only display the result information 12. In this way, the user can clearly identify the number of arrows 20 that have been fired and the number of arrows 20 remaining in a safe state.

[0013] Continuing from the above, the second type involves the sensing component 2 being positioned within the arrow magazine 102 (regardless of whether it's inside or outside; the placement varies depending on the type of sensing component 2, see Figures 7 to 12 for examples of its placement inside the arrow magazine 102). Simply put, when the arrow magazine 102, containing a plurality of arrows 20, is assembled onto the bow body 101, the sensing component 2 is electrically connected to the microcontroller 1 located on the bow body 101, forming a closed electrical circuit. Therefore, when the arrows 20 in the arrow magazine 102 are removed from the arrow magazine 102 (normally, the sensing component 2 is positioned within the arrow magazine 102...), (If the arrow 20 lands inside and near the exit of the arrow-holding platform 103), the sensing component 2 will sense and detect that an arrow 20 has exited the arrow magazine 102 and generate multiple data information 21 (for example, detecting that an arrow 20 has exited the arrow magazine 102). The multiple data information 21 is then transmitted to the microcontroller 1 and the arithmetic processing unit 11 performs calculations. The calculation method can be referred to the description in the previous paragraph. In summary, through the setting of the sensing component 2, this invention can identify the number of all arrows 20, allowing the user to clearly understand the number of arrows 20 during the entire shooting process.

[0014] In addition, according to the above detection method, in order to provide information about possible abnormal situations involving the arrow 20 during shooting, such as: normally, a single arrow 20 should land on the arrow-holding platform 103, and after being shot, the previous arrow-dropping action should continue, but due to external factors or other problems, two arrows 20 may fall from the quiver 102 at once; or in the cocking mode E, an arrow 20 should have landed on the arrow-holding platform 103, but it did not. Therefore, this case further explains the situation regarding the position of the arrow 20. The main method for making relevant judgments during the movement process is to install the arrow box 102, which contains multiple arrows 20, onto the bow body 101 and activate the connection between the microcontroller 1 and the sensing component 2. When the arrow 20 lands on the arrow placement platform 103, regardless of whether the sensing component 2 is located in the arrow box 102 or the arrow placement platform 103, it can detect the physical changes caused by the movement of the arrow 20. Therefore, the preset data information database 13 built into the microcontroller 1 is used for comparison. The comparison results are used to determine whether the arrow 20 has any abnormalities during the movement, so that the user can take immediate action.

[0015] Based on the above explanation, and having clarified the main technical requirements of this case, the following detailed descriptions all refer to the type between the display module 3 and the bow body 10, and the type of the sensing component 2 being installed on the arrow placement platform 103 or the arrow box 102. Therefore, the following detailed descriptions do not specifically distinguish between the aforementioned types (the sensing component 2 shown in each figure represents different sensing types with different shapes). In order to provide accurate sensing and detection of the sensing component 2, this invention employs any one of the following in the use of the sensing component 2: an optical sensing component, a vibration sensing component, a micro switch component, a mechanical counter, an electromagnetic sensing component, or an electronic tag component. Furthermore, the optical sensing component can be infrared, light-sensitive, or ultraviolet. The sound wave sensing component, using optical detection as an example, is described with the aforementioned sensing component 2 installed on the arrow-holding platform 103. The arrow 20 comprises an arrowhead, shaft, and fletching. When the sensing component 2 is optical, it can detect and sense changes in light and shadow, obstruction, and other optical alterations to make a judgment. The vibration sensing component can be an accelerometer, gyroscope, piezoelectric vibration sensor, vibrometer, etc., which primarily detects the micro-vibrations generated when the arrow 20 lands on the arrow-holding platform 103, the micro-vibrations generated by the bow body 10 after the arrow 20 is fired, and the micro-vibrations generated when the arrow 20 leaves the arrow magazine 102. The micro-switch component can be a basic micro-switch. Microswitch, lever type, pin plunger type, roller plunger, etc., the detection mode of the microswitch component is similar to that of the vibration sensing component, but the actual operation of the micro-motion detection is different from that of the vibration sensing component; the mechanical counter can be a push-type counter, rotary counter, stroke counter, or measuring wheel counter, etc., which can detect and count the movement of the arrow 20 according to the position set by the sensing component 2; the electromagnetic induction component can be an inductive proximity sensor, a Hall effect sensor, dynamic electromagnetic induction (such as metal passing through a coil), etc., because some arrows 20 are made of metal, so the number of arrows can also be detected by electromagnetic induction;Finally, the electronic tag component can be RFID, active tags, passive magnetic stripe / EAS tags, UWB (Ultra-Wideband Tag), etc. Electronic tags can be set on each arrow 20, and the sensing component 2 is a sensor capable of sensing the electronic tags. During the movement and firing of each arrow 20, the sensor can detect the position of the arrow 20, thereby achieving quantity detection and calculation. This provides relevant multiple data information 21, which is transmitted back to the microcontroller 1. After processing by the arithmetic processing unit 11, the result information 12 is displayed on the display module 3. The above description of the sensing component 2's detection of each arrow 20 is not limited to the sensing methods listed above. Other methods capable of detecting arrows 20 are also within the scope of protection of this case and are described here.

[0016] Next, in order to ensure that the user can be immediately aware of and resolve any abnormal situations such as abnormal movement or firing of the arrow 20, the microcontroller 1 further incorporates an alarm module 15. This module detects when the sensing component 2 is operating, specifically when the arrow 20 abnormally falls onto the arrow-holding platform 103 or abnormally withdraws from the arrow magazine 102. (The term "abnormal" refers to an excessively fast or long interval between the arrow 20 falling or withdrawing from the magazine; this is primarily determined by the detection method of the sensing component 2 and depends on the criteria for judging abnormalities. It could also include abnormal firing of the bowstring 30, abnormal pulling of one of the triggers 104 on the bow body 10, multiple arrows 20 simultaneously placed on the arrow-holding platform 103, no arrows 20 placed on the arrow-holding platform 103, abnormal firing frequency, or multiple arrows...) (Factors such as arrow 20 being stuck in the arrow box 102, arrow 20 being ejected from the arrow box 102 without arrow 20, or bowstring 30 being fired without arrow 20, etc.) The sensing component 2 transmits an alarm activation message 22 to the alarm module 15. After receiving the alarm activation message 22, the alarm module 15 sends an alarm signal 151 to the display module 3 for display. In this way, the user can see the abnormal description or warning on the display module 3 (see the process of the aforementioned inspection step (A) S41). In addition, after the display module 3 displays the warning signal 151, the alarm module 15 can also generate a troubleshooting tutorial based on the content of the warning signal 151, providing the user with the correct tutorial to troubleshoot the problem and improve safety, as shown in Figures 1 and 7.

[0017] Continuing from the previous explanation, in order to allow users to stop operation upon noticing warnings or abnormalities, in addition to displaying the warning on the display module 3, the bow body can also be provided in different modes to prevent the user from firing. Therefore, before the explanation, the bow body 101 will be described. The bow body 101 further includes a trigger firing part 105 (containing the aforementioned trigger 104 and a trigger guard 107). A drive assembly 106 is located inside the bow body 101 and is mechanically connected to the trigger firing part 105. The drive assembly 106 is used as a control device and component to fire the arrow 20 after the user pulls the trigger 104. The drive assembly 106 controls a bowstring 30 to launch the arrow 20 when the trigger firing part 105 is pulled. Based on the above basic description of the bow body 101, a power drive rod 108 is further provided on the bow body 101 and electrically connected to the microcontroller 1. The power drive rod 108... 8 is mainly used to block the internal parts of the bow body 101 and the trigger 104 by electric drive, not to restrict its structure. It can also be a screw, etc. When the warning module 15 built into the microcontroller 1 receives the warning activation message 22, the microcontroller 1 further activates the operation of the power drive lever 108 and blocks the drive group 106 or the trigger firing part 105 (for example, the power drive lever 108 will drive and block the movement between any two parts of the drive group 106, or be driven from the trigger guard 107 to protrude and block the trigger 104 to restrict the pulling). This prevents the drive group 106 from moving or the trigger firing part 105 from being pulled. In this way, if the user encounters a warning during operation, there is no need to worry about accidentally triggering the trigger. Similarly, when the problem caused by the warning is resolved, the microcontroller 1 can control the power drive lever 108 to release the block and return to the firing state, as shown in Figures 1 and 7.

[0018] Furthermore, to allow users to review detailed information about the movement and firing of each arrow 20 during past shooting sessions (see Figures 1 and 7), the microcontroller 1 further incorporates a memory module 16. This memory module 16 records the time when each arrow 20 lands on the arrow-holding platform 103, the total time, speed, and weight of the arrow 20 as it leaves the arrow magazine 102, and stores this information in a database 161 within the microcontroller 1. This allows users to review their shooting progress after each shot, enabling them to adjust their shooting method and timing, or select different types of arrows 20. This primarily provides users with a more technologically advanced way to make fine adjustments, improving their shooting accuracy and stability. Additionally, it can record the number of shots fired and the stringing time (the stringing time includes the time it takes for the user to string the bowstring and the total time the bowstring has been in use from the beginning to the present, thus providing information for judging the bowstring and bow arm). The data includes the total service life, total usage time (the total usage time can be the total operation time of the bow body 10 from the time it leaves the factory to the present, such as test operation, live shooting operation, etc., which can provide the operator with the judgment of the usage status and wear of the bow body 10), and the results of the calculation and processing unit (the records of the calculation and processing unit can be the results of each calculation). In addition, the aforementioned description uses the setting of the record database 161 to provide users with past history for query. However, in order to pursue better training results, so that users / coaches / trainers can effectively analyze the things that users should pay attention to in shooting, the microcontroller 1 further incorporates an analysis unit 17. The analysis unit 17 analyzes all the data recorded in the record database 161 and can generate a shooting report 171. Users / coaches / trainers can make fine adjustments to subsequent shooting operations through the display of the shooting report 171 to help users improve the accuracy and stability of shooting. The shooting report 171 can be displayed on the display module 3.

[0019] Furthermore, in this era that advocates energy conservation, carbon reduction, and environmental protection, this invention, in order to meet the demands of the times, further incorporates a power-saving / wake-up module 18 into the microcontroller 1. This power-saving / wake-up module 18 detects that if the sensing component 2 fails to detect an arrow 20 placed on the arrow-holding platform 103 or an arrow 20 retracting from the arrow magazine 102 after a certain period of time, it controls the display module 3 to pause display. Taking the display module 3 as the screen 31, the screen 31 will automatically turn off but not stop operating until the sensing component 2 detects another arrow 20 falling onto the arrow-holding platform 103 and retracting from the arrow magazine 102. Group 18 starts the operation of the display module 3, at which time the screen 31 can be displayed. This setting can reduce the power consumption of the microcontroller 1 and the sensing component 2 during operation, and also maintain the service life of the microcontroller 1 and the sensing component 2, as shown in Figures 1 and 7. The above-defined scenarios for pausing the display of the display module 3 can be the initial shooting before the arrow falls, the rest during the shooting process (no arrow falls), loading arrows, etc. During the entire operation, regardless of the previous loading arrow, shooting process, shooting without arrows, etc., as long as the sensing component 2 does not detect the arrow 20 placed on the arrow placement platform 103 within the limited time, the power saving / wake-up module 18 will turn off the display of the display module 3.

[0020] Finally, in order to provide users with the ability to use the device in various locations, such as dimly lit environments, poor visibility areas, or when users need to alleviate eye fatigue from prolonged concentration during operation and find it difficult to view the display module 3 with their eyes, the display module 3 further incorporates a voice unit 32. The voice unit 32 reads the result information 12 generated by the display module 3 and broadcasts it in a virtual voice manner, so that users can hear the results displayed on the display module 3 by listening, as shown in Figures 1 and 7.
