Description

Technical Field

[0001] The invention relates to an arrow for a crossbow, in particular to a kinetic and potential energy conversion guided arrow. Background Art

[0002] As a shooting tool, the crossbow has been used throughout human history and has played a very important role. Traditional crossbow arrows are generally made of bamboo or wood, and the arrow shaft is solid, mostly used for hunting or war. As time goes by, the emergence of firearms gradually replaced the crossbow, making it lose some of its original functions, but archery still has a strong vitality as a sport.

[0003] Since traditional arrows are heavy and have a large length-to-diameter ratio, and are only acted upon by a single tail thrust, after being shot, they will inevitably experience instability and torsion, that is, the arrow shaft will torsionally wobble left and right during flight. Therefore, in order to improve the performance of archery, arrow-making technology is constantly being improved. Nowadays, carbon fiber or aluminum alloy is generally used for arrow making, and arrows with solid or hollow shafts of various structures have also appeared. However, the torsion instability phenomenon is still relatively serious, which has a great impact on the 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 precision.

[0005] In order to solve the above technical problems, the kinetic and potential energy conversion guided arrow of the present invention includes an arrow shaft, an arrowhead installed at the front of the arrow shaft, and an arrow tail installed at the tail of the arrow shaft; the arrow shaft is a hollow rod, and its inner cavity is provided with an energy storage device for converting kinetic energy into potential energy for storage and transfer; the energy storage device includes a slider capable of moving in the inner cavity and a spring arranged on one side of the slider.

[0006] The energy storage device comprises a compression spring arranged at the bottom of the inner cavity and a sliding block located at the front end of the compression spring.

[0007] The arrow head is provided with a slide block placement groove, and the arrow tail is provided with a spring placement groove.

[0008] The sliding block is provided with a central hole.

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

[0010] An arrowhead mounting groove and an arrow tail mounting groove are respectively formed at two ends of the arrow shaft; the arrowhead is mounted in the arrowhead mounting groove through a threaded connection, and the arrow tail is mounted in the arrow tail mounting groove through a threaded connection.

[0011] The tail of the arrow shaft is provided with a feather sleeve, and the feather sleeve is provided with a plurality of feathers evenly distributed along the circumference.

[0012] The number of the arrow feathers is three.

[0013] The arrow tail is provided with an arrow tail groove.

[0014] The advantages of the present invention are: a hollow arrow shaft is adopted and an energy storage device composed of a compression spring and a slider is installed therein, which can convert kinetic energy into elastic potential energy for storage and transfer, and at the same time adjust the center of gravity of the arrow body, and convert the original single tail thrust into a combination of elastic force and tail thrust, thereby improving the stability of the arrow when it is shot, eliminating the unstable torsion phenomenon, and also improving the range and accuracy of the arrow after it is shot; the arrow head adopts a lightweight arrow head, which is more convenient to adjust the center of gravity of the arrow body in conjunction with the internal structure of the arrow shaft; the arrow head and the arrow tail are detachable, and the overall assembly is more convenient, and a slider placement groove and a spring placement groove are respectively opened thereon, so that the energy storage device has a larger activity space, the potential energy storage position is further back, and the position of applying the converted kinetic energy to the arrow body is further forward, which has a better effect of improving the stability of the arrow body and the range accuracy; the same internal structure can be applied to bows and arrows or crossbows, and the application scenarios are wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a front cross-sectional view of the present invention; Figure 2 is an enlarged view of the arrow tail of the present invention; Figure 3 It is an enlarged view of the arrow of the present invention. DETAILED DESCRIPTION

[0016] The kinetic and potential energy conversion guided arrow of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] As shown in the figure, the kinetic and potential energy conversion guided arrow of the present invention comprises an arrow shaft 1, a detachable arrowhead 2 installed at the front of the arrow shaft 1, and a detachable tail 3 installed at the tail of the arrow shaft 1. The arrow shaft 1 is a hollow shaft, and an arrowhead mounting groove 9 and a tail mounting groove 10 are respectively opened at both ends thereof. The arrowhead 2 is installed in the arrowhead mounting groove 9 by threaded connection, and the tail 3 is installed in the tail mounting groove 10 by threaded connection; the arrowhead 2 is a lightweight arrowhead, and a tail groove 13 is opened on the tail 3.

[0018] The hollow inner cavity of the arrow shaft is provided with an energy storage device for converting kinetic energy into potential energy for storage and transfer, and the energy storage device includes a compression spring 4 arranged at the bottom of the inner cavity and a slider 5 located at the front end of the compression spring 4 and fixedly connected thereto; the slider 5 is a cylindrical counterweight block with a diameter slightly smaller than the diameter of the inner cavity of the arrow shaft, and a center hole 8 is opened in the center thereof for balancing the air pressure on both sides so that the slider 5 can move smoothly in the inner cavity; a slider mounting groove 6 is opened on the arrow head 2, and a spring mounting groove 7 is opened on the arrow tail 3, and 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.

[0019] When used as a bow and arrow, a feather cover 11 can be installed at the tail of the arrow shaft 1, and three feathers 12 evenly distributed along the circumference are arranged on the feather cover 11. When used as a crossbow arrow, it is not necessary to install it.

[0020] When assembling the arrow body, first screw the tail 3 into the tail of the arrow shaft 1, then put the compression spring 4 together with the slider 5 into the arrow shaft cavity, so that the end of the compression spring 4 extends into the spring mounting groove 7 and contacts its end surface, then use the slider mounting groove 6 in the arrow 2 to cover the slider 5, and screw the arrow 2 into the front part of the arrow shaft 1; if there is a need to install the feather cover 11, the feather cover 11 can be directly installed on the tail 3.

[0021] When the arrow is shot, the slider 5 moves relatively toward the arrow tail in the inner cavity, and the compression spring 4 is compressed by the 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 toward the arrow tail, the stability is improved and the unstable torsional swing phenomenon is eliminated; after the arrow is shot, the slider 5 moves relatively toward the arrow direction in the inner cavity under the action of elastic potential energy, so that the overall center of gravity of the arrow body moves toward the arrow direction, and at the same time, the elastic potential energy is converted into kinetic energy and transmitted to the front part of the arrow body, thereby completing the storage and transfer of kinetic and potential energy, and converting 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.

[0022] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
