Description

Technical Field

[0001] This application relates to the field of archery equipment, and in particular to an intelligent shock-absorbing bow with active tuning capability and real-time feedback mechanism. Background Technology

[0002] In archery and its equipment, modern compound or recurve bows experience a strong reverse impact force upon release, generating significant high-frequency vibrations. This vibration not only affects the bow's stability, causing the arrow's trajectory to deviate from the intended target and reducing shooting accuracy, but it also transmits to the user's arm through the bow handle, leading to muscle fatigue and discomfort. Long-term accumulation of this vibration may increase the risk of sports injuries. Current mainstream solutions include adding passive shock absorbers made of elastic materials such as silicone or rubber to key parts of the bow (e.g., the handle and limb connections), or adding dampers to the bowstring. These methods absorb some energy through the deformation of the materials themselves, mitigating the vibration amplitude to some extent. Furthermore, some high-end products attempt to use a fixed-weight damping structure, altering the system's vibration characteristics by increasing local mass.

[0003] However, existing technologies have significant limitations. First, passive damping blocks or fixed damping structures are "one-size-fits-all" designs with relatively fixed damping frequencies, making it difficult to adapt to the complex vibration spectrum generated by different draw weights, arrow weight combinations, and diverse shooting actions (such as variations in release techniques). This leads to unstable damping effects: they may be effective for certain specific conditions, but perform poorly for vibrations with a wider frequency band or individual user differences, failing to precisely match the bow's resonance point to maximize damping efficiency. The core reason for this deficiency is that the parameters of existing damping structures (especially effective mass and stiffness) cannot be easily and quickly adjusted dynamically on-site, lacking the ability to specifically tune for the dynamic response of a particular bow. Second, existing equipment generally lacks the ability to monitor and quantitatively assess vibration characteristics during shooting in real time. Users or instructors can only rely on subjective feelings (such as numbness in the arm) or the final landing deviation to indirectly judge the impact of vibration, lacking scientific data support and making it difficult to accurately identify the root cause of the problem (such as whether the release action triggers additional torsional vibration), hindering training efficiency and precise optimization of operational techniques. Furthermore, the adjustment of traditional fixed counterweight dampers often requires specialized tools for complex disassembly and reassembly and repeated weighing, which is cumbersome and time-consuming and cannot meet the adjustment needs that require immediate response during training or competition.

[0004] Therefore, it is of great significance to develop an intelligent shock absorber with active tuning capability and real-time feedback mechanism. Utility Model Content

[0005] The purpose of this application is to overcome at least one deficiency of the existing technology and provide an intelligent shock-absorbing bow with active tuning capability and real-time feedback mechanism. The shock-absorbing bow dynamically matches the vibration characteristics of the bow body through a flexibly tuned shock-absorbing core, which significantly improves energy absorption efficiency to stabilize the flight trajectory of the arrow. The synchronous integrated vibration monitoring provides objective basis for technical action analysis and transforms experience-based training into a data-driven mode.

[0006] To achieve the above objectives, this application discloses an intelligent shock absorber with active tuning capability and real-time feedback mechanism. The shock absorber includes a bow body and at least one tuned mass damping shock absorber, wherein the tuned mass damping shock absorber is detachably installed through a fixed interface pre-placed on the bow body. The tuned mass damping shock absorber consists of at least one counterweight, a movable base for mounting the counterweight, a fixed base, and multiple elastic coupling connectors connecting the two. The fixed base is used to connect to the fixed interface of the bow body, and the movable base is arranged coaxially with the fixed base and elastically connected to the fixed base through the elastic coupling connectors.

[0007] The movable base is provided with a first magnet assembly at one end away from the fixed base, and a second magnet is embedded inside the counterweight. The two magnetic end faces of the second magnet are exposed or flush with the end surface of the counterweight. The first magnet at the end of the movable base and the second magnet of the counterweight are attached and fixed by magnetic attraction.

[0008] Furthermore, to enhance the stability and positioning accuracy of the connection, the end face of the movable base facing the counterweight has at least one groove or protrusion positioning structure. Correspondingly, the end face of the counterweight that mates with the movable base has a complementary protrusion or groove structure. This mating structure provides additional radial constraint and circumferential limiting on top of magnetic attraction, preventing the counterweight from shifting relative to the movable base. In addition, complementary positioning structures are also provided on the end faces of the counterweights facing adjacent counterweights, enabling multiple counterweights to interlock and form a stable counterweight assembly.

[0009] Furthermore, the multiple elastic coupling connectors have an arc-shaped bending configuration in their natural state. Their first end is fixedly connected to the side wall of the fixed base, and their second end is fixedly connected to the side wall of the movable base. This connection allows the elastic coupling connectors to undergo elastic deformation when the movable base moves axially relative to the fixed base, thereby generating an elastic restoring force and dissipating vibration energy.

[0010] Furthermore, the vibration sensing component is disposed inside the fixed base, and the fixed base integrates the vibration sensing component, which includes a battery, a circuit board connected to the battery, a microcontroller and an accelerometer integrated on the circuit board, and a storage unit connected to the microcontroller. The accelerometer collects the vibration signal received by the bow body or the fixed base in real time and converts it into an electrical signal. The microcontroller receives the signal data output by the accelerometer, processes it, and stores the data in the storage unit.

[0011] Furthermore, the circuit board also includes a power supply interface for battery charging.

[0012] Furthermore, the fixing interface between the tuned mass damper and the bow body preferably adopts a threaded connection structure to achieve detachable installation and locking. This design allows users to quickly install, remove, or replace the tuned mass damper as needed.

[0013] Furthermore, the elastic coupling connector is a steel rope.

[0014] Furthermore, the circuit board of the vibration sensing component integrates a wireless communication module connected to the microcontroller; the wireless communication module is preferably a Bluetooth module. The microcontroller transmits the processed vibration data and historical records to an external receiving terminal through the wireless communication module for subsequent operational behavior analysis or technical guidance.

[0015] Compared with the prior art, this application has at least one of the following beneficial technical effects:

[0016] 1. Achieve dynamic on-site tuning and efficient adaptation of damping frequency: By quickly adding, removing, or replacing counterweights through magnetic structure and complementary positioning components, combined with the stiffness characteristics of elastic coupling connectors, the tuned mass damping damper can instantly adjust its own resonant frequency to accurately match the main vibration frequency band of the bow under different tension, arrow weight, and shooting actions, significantly improving the broadband damping effect.

[0017] 2. Provides quantitative vibration data to guide operation optimization: The accelerometer integrated into the fixed base collects vibration signals in real time. After being processed by the microcontroller, the signals are transmitted to the terminal via a wireless module, enabling multi-dimensional quantitative analysis of the vibration of the release action. This provides objective data support for users to make technical corrections and training strategies.

[0018] 3. Balancing efficient shock absorption with ease of use: The magnetic counterweight allows for quick adjustment without the need for tools, the threaded interface enables quick installation and removal of the shock absorber, and the pre-bending design of the elastic coupling connector, along with magnetic positioning, ensures system stability and maintains high reliability in complex usage scenarios.

[0019] The beneficial effects listed above are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other descriptive sections of this application. Attached Figure Description

For the sake of brevity and / or clarity, techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail; however, where appropriate, such techniques, methods, and apparatus should be considered part of this specification.

[0029] See attached document Figures 1 to 4 The intelligent shock absorber bow of this embodiment consists of a bow body 1 and at least one tuned mass damping shock absorber 2, wherein the tuned mass damping shock absorber 2 is detachably connected through a pre-set fixed interface 101 on the bow body 1. Specifically, the fixed interface 101 preferably adopts a standard threaded structure, and this connection method is a well-known technology in the mechanical field. The tuned mass damping shock absorber 2 includes a fixed base 203, a movable base 202, elastic coupling connectors 204, and at least one counterweight 201, wherein the fixed base 203 is fastened to the fixed interface 101, and the movable base 202 is coaxially arranged with the fixed base 203 and elastically coupled through multiple elastic coupling connectors 204. Furthermore, a first magnet assembly is embedded at the end of the movable base 202 away from the fixed base 203, and a second magnet is embedded inside the counterweight 201 with its magnetic end face exposed at or flush with the end face of the counterweight 201. When the counterweight 201 approaches the movable base 202, the first magnet and the second magnet are attracted and fixed by magnetic attraction. This magnetic attraction fixing mechanism is based on the well-known principles of electromagnetism.

[0030] Based on this, to overcome the risk of radial offset in the magnetic connection, the end face of the movable base 202 facing the counterweight 201 is provided with a groove structure or a protrusion structure. Correspondingly, the mating end face of the counterweight 201 is provided with a complementary protrusion structure or groove structure, so that a radial mechanical constraint is formed when the two are in contact. It can be understood that this complementary concave-convex structure works together with the magnetic attraction force to achieve both rapid axial adsorption and ensure circumferential positioning accuracy. In addition, the end faces of the counterweight 201 facing adjacent counterweights 201 are also provided with complementary positioning structures, so that multiple counterweights 201 form a stable axially connected counterweight group through magnetic attraction force and mechanical interlocking. This design is used to adjust the equivalent mass of the system in real time.

[0031] The energy transfer mechanism is then explained: the multiple elastic coupling connectors 204 are preferably multi-strand steel ropes, which naturally exhibit an arc-shaped bending configuration. The first end of each steel rope is metallurgically fixed to the side wall of the fixed base 203, and the second end is fixed to the side wall of the movable base 202 in the same manner. When the bow body 1 vibrates during launch, the movable base 202 undergoes axial displacement relative to the fixed base 203 due to inertia, forcing the steel ropes to undergo elastic deformation and generate restoring force. Simultaneously, vibration energy is dissipated through internal material friction. This tuned mass damping mechanism is a well-known technology in the field of vibration control.

[0032] Furthermore, the fixed base 203 integrates a vibration sensing component, including a battery, a circuit board, and a microcontroller, an accelerometer, and a storage unit mounted on the circuit board. The accelerometer collects vibration signals from the bow body 1 in real time and converts them into electrical signals, which are transmitted to the microcontroller. This signal conversion process is based on the piezoelectric effect or capacitance detection principle, which are well-known technologies in the sensor field. The microcontroller filters the raw signal and stores it in the storage unit. Preferably, the circuit board is provided with a power supply interface for connecting an external power adapter to charge the battery. In addition, a Bluetooth module is added to the circuit board as a wireless communication unit. The microcontroller transmits the processed data to a mobile terminal via the Bluetooth module to generate archery action optimization suggestions.

[0033] The vibration sensing component achieves vibration monitoring through the following mechanism: An accelerometer, based on the piezoresistive effect or capacitive detection principle, captures the three-dimensional vibration acceleration signal of the bow body 1 during the archery process in real time. This vibration signal, after being filtered by a hardware filtering circuit to eliminate high-frequency noise, is input to the microcontroller's analog-to-digital converter interface and converted into a digital signal. Subsequently, the microcontroller executes an embedded program to perform time-domain analysis on the digital signal, including but not limited to calculating the total vibration energy, the dominant frequency characteristic amplitude, and the damping decay time constant, and stores the processing results in a timestamp sequence to the storage unit. Based on this, the Bluetooth module periodically transmits the stored vibration data packets to the paired mobile terminal. The terminal application software parses the data packets to generate a vibration spectrum diagram and a stability rating report, which guides the user in adjusting the release action or the configuration of the counterweight 201. The innovation of this monitoring process lies in transforming mechanical vibration characteristics into quantifiable operational parameters, eliminating the subjective bias of traditional experience-based judgments, and providing objective data support for improving the consistency of archery actions and the accuracy of equipment adaptation.

[0034] In the description of the specific embodiments, technical details or conventional design methods that involve common knowledge in the art (including but not limited to anti-loosening structures for threaded fastenings, optimization of magnetic field distribution of magnet components, basic wiring rules for circuit boards, and standard protocol configurations for wireless communication modules) will not be elaborated upon in this specification. Those skilled in the art can directly implement the relevant design details based on existing technical knowledge; for example, replacing equivalent fastening structures or communication modules should be considered a conventional technical choice. It should be specifically noted that this embodiment is only an illustrative example of the core innovative structure and principle of the present invention. Any reasonable modifications based on the technical concept of the specification (such as adjusting the stacking method of the counterweights 201 or expanding the sensor's measuring range) are conventional technical combinations that can be implemented by those skilled in the art without creative effort, and should not be construed as limiting the scope of protection of this application.
