Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports technology, specifically to a light-emitting arrow tail. Background Technology
[0002] Traditional bow and arrow tail lights typically use a manually operated power switch to control their on / off state, which has several drawbacks in practical use. Firstly, the archer must concentrate on operating the switch while shooting, affecting the continuity and accuracy of the shot. Secondly, manual switches are prone to poor contact and difficulty in operation in complex outdoor environments such as dampness and cold. Furthermore, existing bow and arrow tail lights have a simplistic structural design, often consisting of a simple shell enclosure, lacking optimization for specific usage scenarios. For example, the pressure resistance of the parts in contact with the bowstring is insufficient, making them susceptible to damage from bowstring tension. Battery replacement is inconvenient, with some products even requiring tools for disassembly, and they lack battery storage, leading to easy loss or power depletion when not in use. In addition, the loose connections between the circuitry and the structure result in a bulky product that is inconvenient to carry and use. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a light-emitting arrow tail, including a tube body 1, a lamp head 2 inserted into the top of the tube body 1, a lamp holder 5 slidably installed inside the lamp head 2, a high-brightness LED light 51 fixedly installed on the top of the lamp holder 5, a cover tail 3 installed at the bottom of the tube body 1, a battery 4 installed inside the cover tail 3, a connecting end 41 fixed on the top of the battery 4 and inserted into the tube body 1, a U-shaped slot 21 opened on the outer side of the top of the lamp head 2, a precision positioning groove reserved in the inner wall of the tube body 1, and a circuit board fixed in the positioning groove in the inner wall of the tube body 1, a CPU processor and a gravity acceleration sensor installed on the circuit board inside the tube body 1, the tail end of the arrow is engaged in the U-shaped slot 21, and when the arrow is shot, the gravity acceleration sensor captures the rapidly changing acceleration signal, and the data is handed over to the CPU processor. The CPU processor has a built-in intelligent recognition program based on threshold judgment and dynamic filtering algorithms. By comparing the arrow with preset acceleration thresholds for the firing state (e.g., instantaneous acceleration peak > X m / s² and duration > Y ms) and waveform characteristics, it accurately determines whether the arrow is in the firing state. Upon confirmation of firing, the CPU processor immediately drives the control circuit to illuminate the high-brightness LED 51. For the swing-to-power function, when the sensor detects a swing motion that matches preset characteristics such as a specific direction, frequency, and acceleration change combination, the CPU processor, based on the motion recognition algorithm, controls the taillight to complete the power-on or power-off operation. The gravity acceleration sensor is soldered onto a custom PCB circuit board, ensuring a secure pin connection. Surface mount technology (SMT) is used to improve integration. The CPU processor is installed, and the intelligent recognition and control program is burned in. The program is written in C language, cross-compiled, and downloaded to the processor chip. The high-brightness LED 51 is soldered to the designated position on the circuit board, paying attention to the positive and negative polarity. The CR425 micro battery compartment 4 is fixed to the edge of the circuit board, and the battery compartment spring contacts must be precisely connected to the power lines on the circuit board.
[0023] Accelerometers were used to simulate the acceleration and swinging motion of an arrow after being released, testing the CPU processor's accuracy in recognizing sensor data. Algorithm parameters were adjusted until design requirements were met. A pressure test was conducted on the PC transparent lamp head 2, applying pressure exceeding 1.5 times the maximum tension of the bowstring to check structural integrity. Waterproof and dustproof tests were performed on the entire product to ensure normal operation under IP65 protection standards. A 72-hour continuous lighting aging test verified reliability.
[0024] In this embodiment, the lamp head 2 is a transparent plastic shell. The lamp head 2 is integrally injection molded from high-strength polycarbonate material. As the direct contact end with the bowstring, the internal reinforcing rib structure design is optimized, such as radially distributed triangular reinforcing ribs, so that the compressive strength of this part is increased to more than twice that of the traditional design, effectively resisting the tension of the bowstring and frequent friction. At the same time, while ensuring light transmittance, it reduces the interference of light reflection on the archer's vision.
[0025] In this embodiment, the tube body 1 is formed into a hollow cylindrical structure by precision machining using a 6061-T6 aluminum alloy extrusion molding process. The tube body 1 has a uniform wall thickness of 1.2mm, exhibiting high strength and low density characteristics. Compared to traditional plastic materials, it is 40% lighter, but its bending strength is increased by 50%. A precise positioning groove is reserved on the inner wall of the tube body 1 to fix the circuit board and battery 4, ensuring the stability of the internal components and achieving efficient heat dissipation.
[0026] In this embodiment, the tail cover 3 adopts a split-type perforated aluminum alloy cover design. The bottom of the tube body 1 is fixed with a threaded tube 11, and the top of the tail cover 3 is threadedly connected to the threaded tube 11. The back of the tail cover 3 has a 2mm diameter circular hole, which allows users to quickly disassemble the tail cover 3 by twisting and easily replace the CR425 micro battery 4. The back of the tail cover 3 has a 2mm diameter circular hole. When the tail light is not in use, the user can insert the battery 4 into the hole with the negative terminal facing outward to disconnect the battery 4 from the circuit, realize physical power disconnection, prevent power loss, and at the same time serve as a storage function for the battery 4. In addition, at the connection between the tube body 1 and the tail cover 3, a spring-loaded pin-type power connection structure is adopted. The power pin on the circuit board is precisely aligned with the metal spring in the battery compartment of the tail. When the tail cover 3 is tightened, the spring is deformed by pressure and makes close contact with the pin, forming a stable power path. Compared with the traditional wire welding method, it effectively saves internal space, makes the overall structure more compact, and improves assembly efficiency by 60%.
[0027] In this embodiment, a manual push button switch is provided on the side wall of the tube body 1. After the arrow is retracted, the push button can be manually pushed up to turn off the circuit between the lamp tube and the battery 4 without the aid of any auxiliary tools. The battery 4 is installed at the bottom. The battery 4 is designed to be cylindrical and matches the size of the outer shell. It is assembled by insertion and glued. An O-ring is used to prevent the glue from overflowing before it dries.
[0028] The core circuit of this intelligent arrow tail light consists of a CPU processor, a gravity acceleration sensor, a high-brightness LED 51, and a CR425 micro battery 4. At the moment the arrow is released, the gravity acceleration sensor captures the rapidly changing acceleration signal, and the data is sent to the CPU processor. The CPU processor has a built-in intelligent recognition program based on threshold judgment and dynamic filtering algorithms. By comparing the signal with preset acceleration thresholds for the release state (e.g., instantaneous acceleration peak > X m / s² and duration > Y ms) and waveform characteristics, it accurately determines whether the arrow is in the release state. After confirmation of release, the CPU processor immediately drives the control circuit to illuminate the high-brightness LED 51. Regarding the swing-to-power function, when the sensor detects a swinging motion that matches preset characteristics such as a specific direction, frequency, and acceleration change combination, the CPU processor, based on the motion recognition algorithm, controls the tail light to turn on or off.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
