Description

Technical Field

[0001] This invention relates to the field of archery equipment technology, specifically to a bow and arrow side pad with positioning and speed measuring functions and its measurement method. Background Technology

[0002] A bow and arrow side pad is a device installed on the bow handle to provide lateral contact and adjustment force to the arrow during firing. Traditional bow and arrow side pads typically only have mechanical adjustment functions, that is, they apply an adjustable lateral force to the arrow through a knob, spring, or other structure to counteract the sway of the arrow caused by the bowstring at the moment of firing, allowing it to fly more straight.

[0003] With the increasing demand for scientific and data-driven training in archery, athletes and coaches not only need to adjust arrow trajectories but also require real-time access to key data for each shot, such as the arrow's ready position on the bow (arrow position) and its initial velocity upon release (arrow velocity). This data is crucial for analyzing motion consistency, evaluating equipment performance, and optimizing training programs. However, current bow and arrow pads on the market offer limited functionality and cannot achieve real-time data acquisition and transmission. Archers typically rely on separate, separately installed velocity measuring devices, which often suffer from installation difficulties, alignment problems with the arrow's axis of motion, and the inability to immediately correlate data with specific shooting actions, thus affecting measurement accuracy and training convenience.

[0004] Therefore, there is an urgent need for an integrated solution that deeply integrates data measurement functions with traditional adjustment functions and is directly installed at the key contact points of the arrow's movement path, thereby providing more direct, accurate, and convenient data support. Summary of the Invention

[0005] This invention was made to solve the above-mentioned problems, and its purpose is to provide a bow and arrow side pad with position and speed measurement and a measurement method thereof.

[0006] This invention provides a bow and arrow side pad with position and velocity measurement, characterized by comprising: a protective shell, a measuring component, and an adjusting component. The protective shell is a hollow cylindrical shape for detachably mounting on the bow handle via threads. The measuring component is detachably housed inside the protective shell for measuring the position and velocity of the arrow, and includes the measuring shell, a control board, a light wave emitting sensor, a light wave receiving sensor, and a wireless transmission module. The wireless transmission module is used to wirelessly transmit the measurement data to an external electronic device. The adjusting component is located inside the protective shell. The measuring housing and the protective housing slide together, allowing the measuring component to undergo lateral displacement under the action of the adjusting component.

[0007] The bow and arrow side pad with position and speed measurement provided by the present invention also has the following features: the measuring component further includes a hollow friction rod and a battery. The hollow friction rod is detachably connected to the front end of the measuring housing by a thread, and its axis is consistent with the axis of the measuring housing.

The rotating adjusting sleeve can drive the limiting rod to move axially, thereby compressing the spring and pushing the measuring housing to move laterally through the spring's elastic force.

[0012] The bow and arrow side pad with position and speed measurement provided by the present invention also has the following feature: the hollow friction rod is made of carbon fiber or aluminum.

[0013] The bow and arrow side pad with position and speed measurement provided by the present invention can also have the following feature: the wireless transmission module is a Bluetooth module or a Wi-Fi module.

[0014] The present invention also provides a method for measuring arrows using any of the above-described arrow side pads, characterized by comprising the following steps: Step S1: Adjust the lateral force applied to the measuring housing by rotating the adjusting sleeve; Step S2: On the surface of an arrow, a first colored ring that can slide along its length direction is provided, and at least two second colored rings are provided at equal intervals.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the following embodiments are described in detail with reference to the accompanying drawings.

[0020] Figure 1 This is a schematic diagram of the bow and arrow side pad structure in this invention. Figure 2 This is a schematic diagram of a half-section of the side pad of the bow and arrow in this invention. Figure 3 This is a schematic diagram of the bow and arrow side pads and arrow support in this invention.

[0021] like Figures 1 to 3 As shown, the present invention provides a bow and arrow side pad 100 with position and speed measurement, including: a protective shell 10, a measuring component 20, and an adjusting component 30.

[0022] In this embodiment, the protective housing 10 is in the shape of a hollow column and is used to be detachably mounted on the bow handle by means of threads.

[0023] In this embodiment, the measurement component 20 is detachably housed inside the protective housing 10 and is used to measure the position and velocity of the arrow. It includes a measurement housing 21, a control board 22, a light wave emitting sensor 23, a light wave receiving sensor 24, and a wireless transmission module (not shown in the figure). The wireless transmission module is used to wirelessly transmit the measurement data to an external electronic device.

[0024] The measuring housing 21 and the protective housing 10 are slidably fitted together, so that the measuring component 20 can generate lateral displacement under the action of the adjusting component 30.

[0025] In this embodiment, the measuring component 20 also includes a hollow friction rod 25 and a battery 26. The hollow friction rod 25 is detachably connected to the front end of the measuring housing 21 via threads, and its axis is aligned with the axis of the measuring housing 21. The battery 26 is replaceably installed in the battery compartment inside the measuring housing 21 to power the control board 22. This allows the core electronic measuring component to be removed from the protective housing 10 as an independent module, facilitating separate deep cleaning or troubleshooting without replacing the entire side pad or affecting the bow body. This enables independent maintenance and upgrades of the functional module and reduces long-term operating costs.

[0026] In this embodiment, the rear end of the measuring housing 21 is sealed by a removable rear end plug 27. The battery 26 compartment is located inside the rear end plug 27. The battery 26 can be removed and replaced by loosening the rear end plug 27. This creates an independent, sealed power compartment, which appropriately isolates the battery 26 from the core circuit board in space. This facilitates the replacement of the battery 26 (simply by unscrewing the plug 27) and also improves the heat dissipation and moisture protection of the circuit board, enhancing the environmental adaptability and reliability of the bow and arrow side pad 100 of this invention.

[0027] In this embodiment, the control board 22 is also equipped with a button 221 and an indicator light 222. A transparent button 11 is provided at a corresponding position on the side wall of the protective shell 10. The transparent button 11 is snapped into the protective shell 10, covering the outside of the button 221 and used to transmit the light of the indicator light 222. This achieves seamless integration between the internal and external user interface. The transparent button 11 provides a physical barrier to prevent accidental touches and a good tactile feel, while clearly transmitting the light of the internal indicator lights 222 (such as power indicator, Bluetooth connection status, measurement activation prompt, etc.), making the device status readily apparent and greatly optimizing the human-computer interaction experience.

[0028] In this embodiment, the detection directions of the light wave emitting sensor 23 and the light wave receiving sensor 24 are aligned with the axis of the hollow friction rod 25, allowing the light wave emitted by the light wave emitting sensor 23 to pass through the internal channel of the hollow friction rod 25. This ensures that the measurement optical path is highly coincident with the arrow's motion axis, minimizing measurement errors caused by optical path deviation. The transmission of light waves within the rod also avoids direct interference from external stray light and environmental dust, significantly improving the sensor's operational stability and signal-to-noise ratio in complex outdoor environments.

[0029] In this embodiment, the wireless transmission module is preferably a Bluetooth module or a Wi-Fi module. This completely eliminates the constraints of data cables, allowing the shooter to move freely during training. Data is wirelessly transmitted to the mobile terminal in real time, facilitating immediate viewing, sharing, and in-depth analysis using professional applications. This achieves a smooth and efficient closed loop of "collection-transmission-analysis" for training data. In this embodiment, the hollow friction rod 25 is preferably made of carbon fiber or aluminum.

[0030] In this embodiment, the adjustment assembly 30 is disposed inside the protective housing 10 and includes an adjustment sleeve 31, a limiting rod 32, and a spring 33. The inner wall of the adjustment sleeve 31 is threadedly engaged with the outer wall of the protective housing 10, and its outer surface is provided with scale markings. The limiting rod 32 is disposed inside the protective housing 10, with one end abutting against the adjustment sleeve 31. The spring 33 is disposed between the limiting rod 32 and the measuring housing 21. The rotary adjusting sleeve 31 can drive the limiting rod 32 to move axially, thereby compressing the spring 33, and then pushing the measuring housing 21 to move laterally through the elastic force of the spring 33.

[0031] The specific usage process is as follows: The user first screws the protective housing 10 into the standard side pad mounting hole of the bow handle and tightens it. Then, the adjusting sleeve 31 can be rotated according to personal preference or arrow parameters. The rotation of the sleeve is converted into axial movement of the limiting rod 32 via a threaded transmission, thereby compressing or releasing the spring 33, ultimately changing the magnitude of the lateral force exerted by the spring 33 on the measuring housing 21, completing the pre-adjustment of the lateral support force of the arrow. After preparation, the transparent button 11 is pressed to start the measuring assembly 20, and the control board 22, light wave emission sensor 23, etc., begin operation. When the arrow is strung and rests against the hollow friction rod 25, the first colored ring (adjustable position, used to indicate the firing position) and at least two equidistant second colored rings (used for speed measurement) on the arrow shaft enter the sensing area. The light waves continuously emitted by the light wave emission sensor 23 pass through the internal channel of the hollow friction rod 25 and irradiate the arrow surface, and the light wave receiving sensor 24 receives the light signals reflected back from the colored rings. The control board 22 processes these signals in real time: by identifying the characteristics of the reflected signal from the first ring, it determines the longitudinal position of the arrow before launch (arrow position); by capturing the arrival times of the reflected signals from the two second rings and combining them with the known fixed distance between them, it calculates the passing velocity of the arrow at the moment of release (arrow velocity). The processed position and velocity data are transmitted in real time via a wireless transmission module (such as Bluetooth) to a paired external electronic device (such as a smartphone or tablet) for users to view, record, and analyze.

[0032] Figure 4 This is a flowchart illustrating the measurement method in this invention.

[0033] like Figure 4 As shown, the present invention also provides a method for measuring arrows using any of the above-described arrow side pads 100, comprising the following steps: Step S1: Adjust the lateral force applied to the measuring housing 21 by the adjusting assembly 30 by rotating the adjusting sleeve 31; Step S2: On the surface of an arrow, a first colored ring that can slide along its length direction is provided, and at least two second colored rings are provided at equal intervals. Step S3: Install the bow and arrow side pad 100 onto the bow handle and start the measuring assembly 20; Step S4: Light waves are emitted onto the surface of the arrow through the light wave emitting sensor 23, and light signals reflected from the first colored ring and the second colored ring are received through the light wave receiving sensor 24. Step S5: The control board 22 transmits the processed arrow position data and / or velocity data to an external electronic device via a wireless transmission module.

[0034] In step S5, the control board 22 determines the position of the arrow before launch based on the light signal reflected from the slidable first colored ring, and calculates the launch speed of the arrow based on the time difference between the light signals reflected from at least two equidistant second colored rings and the known spacing between the second colored rings.

[0035] The role and effect of the embodiments The bow and arrow side pad with positioning and velocity measurement and its measurement method according to this invention not only retain the core function of applying precise lateral force to the arrow through adjustment components, but also, through a built-in optical wave sensor and wireless transmission system, simultaneously and automatically collects and wirelessly transmits the arrow's ready-to-fire position and initial velocity without interfering with the archer's normal operating procedures. The overall solution greatly improves the convenience, accuracy, and immediacy of archery training data acquisition, providing a powerful data tool for athlete technical analysis, equipment calibration, and training plan optimization, and promoting the evolution of archery training towards intelligence and precision.

[0036] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
