Description

Bullet sensing device loaded with gun magazine

[1] A bullet sensing device loaded in a gun magazine, which is composed of a plurality of round tubes and a light source, a photoelectric sensing element and a columnar light guiding element, and when the loading position of the internal bullet of the magazine changes, The state of the optical signal received by the photoelectric sensing element is also changed at the same time, and the change of the optical signal received by the photoelectric sensing element is analyzed and compared, thereby whether the bullet in the magazine changes the loading position.

[2] The gun is a deadly weapon with a long history. Because the gun is a light weapon that can be carried around, if it is combined with a vibrating or magnetic induction or acoustic sensing device, it can avoid accidents or mistakes. The resulting gun is caught or misunderstood. However, it is subject to a lot of shaking and vibration when it is carried. Moreover, after the bullet is fired, a large amount of gunpowder dust remaining on the surface of the gun is generated. These factors are possible. The aforementioned sensing device generates a lot of error sensing and false signals, which is also the biggest difficulty that needs to be overcome to develop a safety sensing device for use in a gun.

[3] Most of the guns must be loaded with bullets to fire bullets and produce lethality. Therefore, the present invention is based on the function of providing bullet sensing in the magazine, and can further achieve firearm safety control. The purpose. The gun magazine has a movable positioning base inside, and the bottom of the positioning base has a spring, and the spring provides the power required for the positioning base to be lifted upward, because the magazine is fired after the gun is fired. The uppermost bullet in the interior will leave the magazine and automatically lift the magazine. The remaining bullets inside the magazine can be lifted up by the positioning base at the bottom of the magazine. The present invention and the bullet can respectively move and fill the aforementioned bullet. The space that was originally occupied. [4] The present invention is a bullet sensing device loaded in a gun magazine, which is loaded with the bullet simultaneously in the bullet magazine, which is composed of a plurality of round tubes and a light source and a photoelectric sensing element and a plurality of columns The light guiding component is formed. According to the invention, by sensing the change of the optical signal received by the photoelectric sensing component, it is known whether the bullet in the magazine moves and changes the loading position. [5] The composition of the present invention includes a plurality of round tubes, and since the appearance of the bullet is a conical shape having a small outer diameter of the front end but a large outer diameter of the rear end, the present invention and the bullet are simultaneously loaded inside the magazine. a portion of the surface of the circular tube is separated from the surface of the bullet having a smaller outer diameter at the front end and is not in contact with each other, and the surface of the other tube is in contact with a surface having a larger outer diameter of the rear end of the bullet. In this case, the present invention When the loading position of the bullet inside the magazine changes, the pressing force provided by the different round tubes and the inner wall of the magazine is different. [6] Because the bullet at the top of the magazine inside the magazine automatically picks up and leaves the magazine after the gun is fired, the remaining bullets inside the magazine will move and fill the space occupied by the aforementioned mast, and Because the present invention simultaneously contacts the inner surface of the magazine and the bullet inside the magazine, the tube and the bullet of the present invention are subjected to the present invention in the magazine and the bullet in the moving loading position. The frictional force of the inner wall surface of the magazine is affected by the rotation of the shaft and the movement of the shaft to change its position in the magazine. [7] The power source required for the rotation of the circular tube of the present invention is the force generated by the contact friction between the surface of the round tube and other surfaces. The specific portion of the plurality of tubes of the present invention has the same outer diameter of the tube, and if the present invention is loaded at the bottom of the magazine, at this time, the surface of the bullet having a smaller outer diameter is separated. The surface of the circular tube is only in contact with the side wall surface of the magazine and the surface of the base. Therefore, only two frictional forces generated by the two contact points of the side wall and the base act on the surface of the circular tube. Another round tube of the same outer diameter of the present invention can simultaneously contact the inner wall of the magazine and the surface of the base and the bullet, so that there are more than three frictions generated by more than three contact points at this time. The force acts on the surface of the tube. In this way, the present invention is assembled by combining the two adjacent circular tubes, which are assembled with each other, and because they receive different surface frictional forces at the same time, and the two are freely rotatable, respectively, The round tube can thereby be rotated relative to each other. [8] The present invention is loaded inside the magazine, and the plurality of tubes are independent of each other, and the tubes have different outer diameters, so the tube can be fitted The manners are overlapped and fixed to each other, and the plurality of circular tubes have the same axial position, so that they can freely rotate with their axes as the center of rotation. The surface of the round tube can be covered with a collar having increased resistance, and the surface of the collar can also increase the zigzag pattern which can improve the frictional resistance, thereby increasing the contact friction between the present invention and other joints. [9] The columnar light guiding element of the present invention has the same axial position as the circular tube, and is fixed inside the circular tube, so the cylindrical light guiding element can rotate with the circular tube Rotating, and the light guiding condition of the columnar light guiding element is changed by rotation. At this time, the optical signal condition received by the photoelectric sensing element is also changed at the same time, and the present invention can thereby obtain the movement of the bullet loading position in the magazine. Change the sensing signal. [10] Since the light transmission is not affected by the shaking and vibration of the columnar light guiding element, the sensing device of the present invention can optically sense the false sensing and false signal generated by shaking and shaking.

[12] The number of the columnar light guiding elements of the present invention is plural, the columnar light guiding element is fixed to the axial center position of the circular tube, the columnar light guiding element has a light penetrating plane, and different The light guiding elements of the columnar light guiding elements have a certain distance between the planes. The light generated by the light source is transmitted forward through the guiding of the columnar light guiding element, and the transmitted light may leak out to the outside by the light penetrating plane of the columnar light guiding element, and some of the light that leaks out of the outside may be transmitted by other The light of the columnar light guiding element penetrates the plane into the other columnar light guiding elements and continues to be transmitted, and can continue to be guided to the photo sensing element of the present invention. [13] The plurality of the columnar light guiding elements of the present invention may be a plastic optical fiber or a glass optical fiber, and the columnar light guiding elements are respectively fixed inside different circular tubes, and the light source and the photoelectric sensing element are respectively fixed in different circles. Inside the tube. When the loading position of the internal bullet of the magazine changes, the different round tubes will rotate at different rotation angles. At this time, the light source and the columnar light guiding element connected to the photoelectric sensing element and connected thereto are also generated. The same relative angular rotation changes. [14] Since the columnar light guiding element of the present invention has a light transmission plane, and an angle between a normal line of the foregoing plane and an axis of the columnar light guiding element is between 0 ゚ and 80 ,, Therefore, the columnar light guiding element only needs to undergo a slight rotation change, and the light refracting and light reflecting conditions of the light penetrating plane of the columnar light guiding element are greatly changed, and the photoelectric sensing element passes through the column. The intensity of light that can be received by the light guiding element can also vary greatly, which is also the principle of optical sensing technology used in the present invention. [15] The invention can increase the circumference of the tubular protective tube outside the columnar light guiding element, and can play the function of not affecting the light guiding and rotating of the columnar light guiding element and can simultaneously provide the protection of the operating environment quality. Thereby, the external smoke dust and moisture are prevented from affecting the optical characteristics of the light penetrating plane of the columnar light guiding element. [16] The control circuit combination of the present invention can provide the driving function of the light source and the photoelectric sensing element, and can also provide the function of computing communication and the function of analyzing and comparing the optical signal received by the photoelectric sensing element. The invention can realize whether the bullet in the magazine moves and changes the loading position by sensing the independent operation of the external wire and sensing the change of the optical signal received by the photoelectric sensing element. [17] The control circuit combination of the present invention may additionally connect an acoustic sensor or a vibration sensor, and may combine the operation of the aforementioned sensor with the control circuit and a communication function, thereby increasing the gun The sensing function of the actual shooting situation. [18] The control circuit combination of the present invention can additionally connect a Bluetooth wireless communication component or a radio frequency wireless communication component, and the invention can thereby achieve the function of communicating the use condition of the gun with the external communication by wireless communication. [19] The wireless communication component connected to the control circuit combination of the present invention can communicate with the smart phone in a wireless communication manner, and can also communicate with the smart wearable device by way of wireless communication, and the wearable device can include wisdom. Glasses or smart watches or smart bracelets or smart headphones. [20] Since most of the gun magazines are made of metal materials with radio wave shielding effect, the radio wave transmitting or receiving elements used in the aforementioned Bluetooth wireless communication parts or radio frequency wireless communication are located in the gun bullets. Internally, the communication effect may be affected. Therefore, the present invention may additionally add an auxiliary control circuit combination fixed to the outside of the gun magazine, and the auxiliary control circuit combination may provide a function of assisting the control circuit to combine the communication signal transmission and reception. This can solve the problem of the communication effect of the present invention.
