Description

Technical Field

[0001] This invention relates to an arrow for crossbows, specifically a guided arrow that converts kinetic and potential energy. Background Technology

[0002] As a shooting tool, the bow and crossbow has played a vital role throughout human history. Traditional crossbows were generally made of bamboo or wood, with solid shafts, and were primarily used for hunting or warfare. However, with the development of the times, the advent of firearms gradually replaced the bow and crossbow, causing it to lose some of its original uses. Nevertheless, archery as a sport still retains considerable vitality.

[0003] Because traditional arrows are heavy and have a large length-to-diameter ratio, and are only subjected to thrust from the tail, they inevitably experience instability and wobbling after being fired—that is, the arrow shaft wobbles left and right during flight. Therefore, to improve archery performance, arrow manufacturing processes have been continuously improved. Modern arrows are generally made of carbon fiber or aluminum alloy, and various structures using solid or hollow shafts have also emerged. However, the wobbling and instability phenomenon remains quite serious, significantly impacting range and accuracy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a kinetic and potential energy conversion guided arrow with low torsional instability, long range and high accuracy.

[0005] To solve the above-mentioned technical problems, the present invention provides a kinetic and potential energy conversion guided arrow, comprising an arrow shaft, an arrowhead installed at the front of the arrow shaft, and an arrow tail installed at the rear of the arrow shaft; the arrow shaft is a hollow shaft, and its inner cavity is provided with an energy storage device for storing and transferring kinetic energy after it has been converted into potential energy; the energy storage device includes a slider that can move in the inner cavity and a spring disposed on one side of the slider.

[0006] The energy storage device includes a compression spring disposed at the bottom of the inner cavity and a slider located at the front end of the compression spring.

[0007] The arrowhead has a slider mounting groove, and the tail of the arrow has a spring mounting groove.

[0008] The slider has a central hole.

[0009] The slider is fixedly connected to the compression spring.

[0010] The arrow shaft has an arrowhead mounting slot and an arrow tail mounting slot at both ends; the arrowhead is installed in the arrowhead mounting slot by a threaded connection, and the arrow tail is installed in the arrow tail mounting slot by a threaded connection.

[0011] The arrow shaft is provided with a fletching sleeve at the tail, and the fletching sleeve is provided with multiple fletchings evenly distributed along the circumference.

[0012] The arrow has three fletchings.

[0013] The arrow has a breech groove.

[0014] The advantages of this invention are: It employs a hollow arrow shaft with an energy storage device consisting of a compression spring and a slider installed within it. This device converts kinetic energy into elastic potential energy for storage and transfer, while simultaneously adjusting the arrow's center of gravity. It transforms the original single tail thrust into a combination of elastic force and tail thrust, improving arrow stability during firing, eliminating instability and swaying, and increasing the arrow's range and accuracy. The arrowhead is lightweight, and its internal structure facilitates easier adjustment of the arrow's center of gravity. The arrowhead and tail are detachable, making assembly easier. The slider and spring mounting slots on the arrowheads provide greater flexibility for the energy storage device, allowing the potential energy to be stored further back and the converted kinetic energy to exert force on the arrow more forward, thus improving arrow stability and range accuracy. The same internal structure can be applied to bows or crossbows, broadening its application scenarios. Attached Figure Description

[0018] The kinetic and potential energy conversion guided arrow of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] As shown in the figure, the kinetic and potential energy conversion guided arrow of the present invention includes an arrow shaft 1, a detachable arrowhead 2 installed at the front of the arrow shaft 1, and a detachable arrow tail 3 installed at the rear of the arrow shaft 1. The arrow shaft 1 is a hollow shaft with an arrowhead mounting groove 9 and an arrow tail mounting groove 10 at its two ends, respectively. The arrowhead 2 is installed in the arrowhead mounting groove 9 by a threaded connection, and the arrow tail 3 is installed in the arrow tail mounting groove 10 by a threaded connection. The arrowhead 2 is a lightweight arrowhead, and the arrow tail 3 has an arrow tail groove 13.

[0020] The hollow inner cavity of the arrow shaft is equipped with an energy storage device for storing and transferring kinetic energy after it is converted into potential energy. The energy storage device includes a compression spring 4 located at the bottom of the inner cavity and a slider 5 located at the front end of the compression spring 4 and fixedly connected to it. The slider 5 is a cylindrical counterweight with a diameter slightly smaller than the diameter of the inner cavity of the arrow shaft. It has a central hole 8 in the center to balance the air pressure on both sides and allow the slider 5 to move smoothly in the inner cavity. The arrowhead 2 has a slider mounting groove 6 and the arrow tail 3 has a spring mounting groove 7. The diameters of the slider mounting groove 6 and the spring mounting groove 7 are the same as those of the inner cavity of the arrow shaft.

[0021] When used as a bow and arrow, a fletching sheath 11 can be installed at the tail of the arrow shaft 1. The fletching sheath 11 has three fletchings 12 evenly distributed around the circumference. When used as a crossbow, it is not necessary to install the fletching sheath 11.

[0022] When assembling the arrow body, first screw the arrow tail 3 into the tail of the arrow shaft 1, then put the compression spring 4 along with the slider 5 into the cavity of the arrow shaft, so that the end of the compression spring 4 extends into the spring mounting groove 7 and contacts its end face. Next, use the slider mounting groove 6 in the arrow 2 to fit onto the slider 5, and screw the arrow 2 into the front of the arrow shaft 1. If there is a need to install the fletching sleeve 11, simply fit the fletching sleeve 11 directly onto the arrow tail 3.

[0023] When the arrow is launched, slider 5 moves relative to the arrow tail in the inner cavity. The compression spring 4 is compressed by slider 5 under the action of kinetic energy, and the kinetic energy is converted into elastic potential energy. At this time, the overall center of gravity of the arrow body is biased towards the arrow tail, which improves stability and eliminates the instability and torsional phenomenon. After the arrow is launched, slider 5 moves relative to the arrowhead direction in the inner cavity under the action of elastic potential energy. While the overall center of gravity of the arrow body moves towards the arrowhead direction, the elastic potential energy is converted into kinetic energy and transferred to the front of the arrow body. This completes the storage and transfer of kinetic and potential energy, and transforms the original single tail thrust into a combination of elastic force and tail thrust, so that the arrow can fly smoothly and improve its range and accuracy, realizing the guidance function.

[0024] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
