Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.

Referring to fig. 1, an embodiment of the present invention provides an electronic target-reporting device 900, which is used to automatically detect the impact point position of a shooting shot and complete target-reporting during shooting training. Electronic target drone 900 includes target assembly 100, detection assembly 200, control box 300, sensor mount 400, and temperature sensing assembly 500. Wherein the target assembly 100 has one end interconnected with the sensor mount 400 and the other end standing in a shooting training position so that a trainee can remotely aim at a shot. The detection assembly 200 is disposed on the sensor mounting frame 400 and located at one side of the target assembly 100, and is used for detecting the impact point position of the bullet on the target assembly 100 when the trainee shoots. The control box 300 is disposed at a middle position of the sensor mount 400, and is used for controlling the targeting assembly 100, the detection assembly 200 and the temperature sensing assembly 500. The sensor mounting bracket 400 is disposed at one side of the target assembly 100, and is used for supporting and carrying the target assembly 100, the detection assembly 200 and the control box 300, and is connected to the temperature sensing assembly 500. The temperature sensing assembly 500 is disposed proximate to the sensor mount 400 for sensing the ambient temperature proximate to the electronic target indicator 900. When the trainee shoots the target assembly 100 from the shooting position, the sensing assembly 200 senses the flight trajectory of the bullet warhead to generate corresponding sensing point coordinates. The control box 300 receives the detected point coordinates, processes the detected point coordinates based on a preset rule to generate the shooting point coordinates of the warhead, and controls the electronic target drone 900 to perform a target-shooting operation, such as displaying the shooting point coordinates or playing the shooting point coordinates with sound. The temperature sensing assembly 500 detects the ambient temperature near the electronic target indicator 900 and provides the generated temperature signal to the control box 300, and the control box 300 performs a correction operation on the coordinates of the detected point based on the temperature signal, thereby performing more accurate correction on the coordinates of the impact point.

Referring collectively to fig. 2, the target assembly 100 includes a target plate 110 and a target mount 120. The target plate 110 is fixedly attached to one end of the target holder 120 and stands upright in a shooting training position so that a trainee can aim a shot remotely. The other end of the target holder 120 is fixedly coupled to one side of the sensor mount 400 to fixedly couple the target plate 110 to the sensor mount 400. In the present embodiment, the target plate 110 has a square structure. In other embodiments, the target plate may be in other shapes, such as a circular or man-shaped configuration. The centerline of the target plate 110 coincides with the centerline of the sensor mount 400 to form a more symmetrical sensing system for the detection and processing of the impact point coordinates.

The target fixing frame 120 includes two sets of fixing members symmetrically disposed at both sides of the center line of the target plate 110 and respectively connected to both sides of the lower end of the target plate 110, so as to more stably and fixedly support the target plate 110. Each set of fixing components includes a support rod 122, a fixing rod 124 and an adjusting screw 126. The support rod 122 is a sleeve structure, and a sleeve hole is arranged in the middle. The fixing rod 124 can be inserted into the sleeve hole of the supporting rod 122 in a vertical sliding manner. In the embodiment, the supporting rod 122 has a square sleeve structure, and the fixing rod 124 has a corresponding square structure at its outer periphery to match with the square sleeve structure of the supporting rod 122. In other embodiments, the supporting rod 122 may also be a sleeve structure with other shapes, such as a circular sleeve structure, an oval sleeve structure, etc., and the outer circumference of the fixing rod 124 may also be a corresponding shape. In some embodiments, the sleeve structure of the supporting rod 122 may also be different from the outer circumference shape of the fixing rod 124, as long as the fixing rod 124 can be slidably inserted into the sleeve structure of the supporting rod 122. In order to realize that the fixing rod 124 can be inserted into the sleeve structure of the supporting rod 122, the rod diameter of the fixing rod 124 is slightly smaller than the bore diameter of the sleeve structure of the supporting rod 122. It should be noted that if the difference between the rod diameter of the fixing rod 124 and the bore diameter of the sleeve structure of the supporting rod 122 is too large, the connection relationship between the two is not firm and is easy to loose, so that the structure of the target assembly 100 is not firm and the actual shooting training effect is affected.

In this embodiment, a sidewall of the supporting rod 122 is provided with an insertion hole, and the fixing rod 124 is provided with a corresponding threaded hole. The adjusting screw 126 can pass through the insertion hole of the supporting rod 122 and then be screwed with the threaded hole of the fixing rod 124, thereby fixedly connecting the fixing rod 124 to the supporting rod 122. The support rod 122 includes an insertion hole, and the fixing rod 124 includes two threaded holes, which are disposed on the fixing rod 124 in a radial direction of the fixing rod 124. When the height of the target assembly 100 needs to be adjusted, the adjusting screw 126 is taken out of one threaded hole of the fixing rod 124, then the fixing rod 124 is slid along the sleeve interface of the supporting rod 122 to adjust the position of the inserting hole of the supporting rod 122 corresponding to the other threaded hole of the fixing rod 124, and then the adjusting screw 126 is inserted from the inserting hole of the supporting rod 122 to be in threaded connection with the other threaded hole of the fixing rod 124. At the same time, the support rod 122 and the fixing rod 124 of the other fixing assembly in the symmetrical position are correspondingly operated, so that the height adjustment of the target assembly 100 is realized. In order to achieve a firm and stable connection between the support rod 122 and the fixing rod 124, the aperture of the insertion hole of the support rod 122 may be slightly larger than the outer diameter of the adjusting screw 126.

In other embodiments, the support rod 122 may also be provided with a plurality of sockets, and the sockets may also be threaded holes, and the fixing rod 124 may also be provided with more than two threaded holes, so as to provide more options for adjusting the height of the target assembly 100. In addition, in other embodiments, the supporting rod 122 may also be provided with a threaded hole at a side opposite to the insertion hole, so that the adjusting screw 126 may pass through the insertion hole of the supporting rod 122 and the threaded hole of the fixing rod 124, and further be in threaded connection with the threaded hole at the other side of the supporting rod 122, so as to more firmly connect the supporting rod 122 and the fixing rod 124 together. In addition, in some embodiments, the insertion holes of the support rods 122 may be replaced with threaded holes.

One end of the securing rod 124 is attached to the target plate 110. In this embodiment, one end of the fixing rod 124 and the target plate 110 are aligned and connected to each other. In other embodiments, the fastening bar 124 may be disposed on the back of the target board 110 and fastened to the back of the target board 110 by means of a screw connection. In other embodiments, the retaining rod 124 may be integrally formed with the target plate 110 or may be attached thereto in other ways to provide a more secure attachment.

Referring collectively to fig. 3-6, the detection assembly 200 includes a first sensor array 210 and a second sensor array 220. The first sensor array 210 and the second sensor array 220 are sequentially arranged in front of the target plate 110. The first sensor array 210 has a first detection range 216 for detecting impact points on the target board 110, and the second sensor array 220 has a second detection range 226 for detecting impact points on the target board 110. During the process that the warhead sequentially passes through the first detection range 216 and the second detection range 226, the first sensor array 210 generates a first detection point coordinate first, and the second sensor array 220 generates a second detection point coordinate later. The first sensor array 210 and the second sensor array 220 each transmit the first detection point coordinates and the second detection point coordinates to the control box 300 for subsequent processing. The first sensor array 210 and the second sensor array 220 are both parallel to the target plate 110.

The first sensor array 210 includes three first sensors 212. The three first sensors 212 are connected in a line at equal distances and parallel to the plane of the target plate 110. The first sensor 212 among the three first sensors 212 is located at a position corresponding to the position of the center line of the target board 110. The second sensor array 220 includes three second sensors 222. The three second sensors 222 are connected in a line at equal distances and parallel to the plane of the target plate 110. The second sensor 222 among the three second sensors 222 is located at a position corresponding to the position of the center line of the target board 110.

With combined reference to fig. 4-5, the three first sensors 212 collectively define a first detection range 216. Upon detecting the bullet crossing the first detection range 216, the three first sensors 212 generate first detection point coordinates for a first intersection 902 of the bullet with the first detection range 216. The three second sensors 222 together form a second detection range 226. When the detection warhead in the flight of the bullet passes through the second detection range 226, the three second sensors 222 generate second detection point coordinates for the second intersection 904 of the second detection range 226. After receiving the coordinates of the first detection point and the coordinates of the second detection point, the control box 300 processes the combination of the coordinates of the detection points at least including the coordinates of the first detection point and the coordinates of the second detection point according to the preset rule to generate the coordinates of the intersection 906 of the warhead on the target surface of the target plate 110, i.e., the coordinates of the landing point. Further, the control box 300 may calculate the speed of the bullet when hitting the target board 110 based on the first detection point coordinates and the second detection point coordinates.

The first sensor 212 and the second sensor 222 are both shock wave sensors for detecting shock waves on the warhead. In other embodiments, the first sensor 212 and the second sensor 222 may be other types of wave sensors, such as ultrasonic sensors. The first sensor 212 and the second sensor 222 are identical in their respective configurations. The first sensor 212 further includes a sensor housing, a sensor rubber gasket, a sensor body, a sensor protective cover, and a sensor connection wire 214. The second sensor 222 further includes a sensor housing, a sensor rubber gasket, a sensor body, a sensor protection cover, and a sensor connection wire 224. The sensor housing is made of plastic to prevent noise from being generated or an error signal caused by the sensor mount 400 from being transmitted. The sensor housing is assembled by screwing back and forth. The sensor body is mounted on the sensor housing by a sensor rubber gasket for providing a shock absorbing and cushioning effect for the sensor to further ensure a smooth working environment for the first sensor 212 and the second sensor 222. The thickness of the sensor rubber pad was 3 mm. The sensor protective cover is arranged outside other components of the sensor to provide protection, wherein a certain gap is reserved between the sensor body and the top of the sensor protective cover to avoid the influence of direct contact on the detection work of the sensor. The thickness of the upper surface of the sensor protective cover is less than 0.5 mm. The sensor protection cover includes a through hole, and an area of the sensor protection cover excluding the through hole should achieve an electromagnetic shielding effect. The sensor connecting wires 214 and 224 are covered with electromagnetic shielding material to prevent the internal transmission signals from being interfered by the outside.

The control box 300 is disposed at a middle position of the sensor 400, and is configured to receive the first detection point coordinates generated by the first sensor 212 and the second detection point coordinates generated by the second sensor 222, receive the temperature signal generated by the temperature sensing assembly 500, and perform a correction operation on the first detection point coordinates and the second detection point coordinates with the temperature signal based on a preset correction rule. The control box 300 further processes a combination of the detection point coordinates including at least the first detection point coordinates and the second detection point coordinates according to the corrected first detection point coordinates and second detection point coordinates by a preset rule to generate pop-up point coordinates, and outputs the pop-up point coordinates to the electronic target drone 900 through the data communication line to perform a target-scoring operation. The control box 300 is provided with through holes to pass through data communication lines, sensor connection lines 214, 224, and other signal lines. The control box 300 includes a control panel, a level gauge, a laser calibration source, a battery, a status indicator light, and a power switch. A level gauge is provided at the top of the control box 300 for observing and securing the level of the sensor mount 400. The laser calibration source is disposed on one side of the control box 300 for correcting the relative position between the sensor mount 400 and the target plate 110. The control board is disposed inside the control box 300, and is used for completing data processing and transmission operations of the control box 300.

The sensor mount 400 is used to mount and carry the sensing assembly 200 and the control box 300. Sensor mount 400 includes a support frame 410, a mount post 420, and a mount rubber gasket 430. The support frame 410 is a main body portion of the sensor mount 400 for mounting and carrying other components. The support frame 410 is used to mount the target mount 120 holding the target assembly 100. The number of the mount supports 420 is 4, and the mount supports are respectively provided at four corners of the sensor mount 400. The mount supporter 420 has one end supporting a bottom surface connected to one corner of the sensor mount 400 and the other end supporting a bearing surface. In an actual training place, the bearing surface may be the ground of the training place. The number of the mounting rubber pads 430 is 6, and the number of the mounting rubber pads is respectively arranged between the first sensor 212, the second sensor 222 and the top surface of the sensor mounting frame 400, so as to ensure the working stability of the electronic hit-indicating device 900.

In the present embodiment, the supporting frame 410 is a rectangular grid structure, and one side of the long side thereof is used for mounting the target holder 120 for fixing the target assembly 100. The support frame 410 is an integrated structure, which can minimize the installation error of the sensor. Referring to fig. 3, the supporting frame 410 includes two long side rods 412 parallel to each other, two short side rods 414 parallel to each other, and two middle support rods 416. The interior of the support frame 410 includes hollow trace channels to receive signal lines of the electronic hit finder 900. The first sensor array 210 is mounted and carried on the upper end of the long side bar 412 remote from the target board 110 and the second sensor array 220 is mounted and carried on the upper end of the long side bar 412 near the target board 110. Wherein, the three first sensors 212 are equidistantly arranged on the upper end surface of the long-side rod 412 far away from the target plate 110. The sensors 212 among the three first sensors 212 are disposed at the middle position away from the long side bar 412 of the target plate 110, and the sensors 212 on both sides of the three first sensors 212 are disposed at the both end positions away from the long side bar 412 of the target plate 110. The three second sensors 222 are equidistantly disposed near the upper end surface of the long side bar 412 of the target plate 110. The sensor 222 in the middle of the three second sensors 222 is disposed near the middle of the long side bar 422 of the target board 110, and the sensors 222 on both sides of the three second sensors 222 are disposed near both ends of the long side bar 412 of the target board 110. The two middle support rods 416 are respectively overlapped at the positions close to the middle of the two long side rods 412 and used for installing and carrying the control box 300. The lower end face of the long-side rod 412 far away from the target board 110 is opened to form a recessed routing channel for receiving a part of the line of the sensor line 214 of the first sensor 212. The lower end face of the long-side rod 412 near the target board 110 is opened to form a recessed routing channel for receiving the sensor wire 224 of the second sensor 222 and a part of other signal wires. The lower end faces of the two support rods 416 are opened to form a recessed routing channel for receiving the sensor line 214 of the first sensor 212, the sensor line 224 of the second sensor 222 and other signal lines.

The end of the mounting bracket post 420 near the bearing surface has an inverted conical structure, and the portion of the inverted conical structure that contacts the bearing surface has a larger contact surface. In the present embodiment, the mounting bracket support 420 is an integral structure to provide a more stable supporting effect. In another embodiment, as shown in fig. 8, the mounting bracket post 420 may also be height adjustable to achieve more selective shooting training height and better installation environment adaptability. The mounting bracket support column 420 includes a support rod 422, a fixing rod 424 and an adjusting screw 426. The support rod 422 is a sleeve structure, and a sleeve hole is arranged in the middle. The fixing rod 424 can be inserted into the sleeve hole of the supporting rod 422 in a vertical sliding manner. In the present embodiment, the supporting rod 422 is a square sleeve structure, and the periphery of the fixing rod 424 is a corresponding square structure to match with the square sleeve structure of the supporting rod 422. In other embodiments, the support rod 422 may have a sleeve structure with other shapes, such as a circular sleeve structure, an oval sleeve structure, etc., and the outer circumference of the fixing rod 424 may have a corresponding shape. In some embodiments, the sleeve structure of the support rod 422 may also be different from the outer circumference shape of the fixing rod 424, as long as the fixing rod 424 can be slidably inserted into the sleeve structure of the support rod 422. In order to realize that the fixing rod 424 can be inserted into the sleeve structure of the supporting rod 422, the rod diameter of the fixing rod 424 is slightly smaller than the diameter of the sleeve structure of the supporting rod 422. It should be noted that if the difference between the rod diameter of the fixing rod 424 and the bore diameter of the sleeve structure of the support rod 422 is too large, the connection relationship between the two is easily unstable and easy to loose, so that the structure of the support column 420 of the mounting frame is unstable, and the sensor mounting frame 400 is further unstable, thereby affecting the actual shooting training effect.

In this embodiment, a sidewall of the support rod 422 is provided with a plug hole, and the fixing rod 424 is provided with a corresponding threaded hole. The adjusting screw 426 may pass through the insertion hole of the support rod 422 and be threadedly coupled with the threaded hole of the fixing rod 424, thereby fixedly coupling the fixing rod 424 to the support rod 422. The support rod 422 includes an insertion hole, and the fixing rod 424 includes two threaded holes, which are disposed on the fixing rod 424 along a radial direction of the fixing rod 424. When the height of the mounting bracket supporting column 420 needs to be adjusted, the adjusting screw 426 is taken out of one threaded hole of the fixing rod 424, then the fixing rod 424 slides along the sleeve interface of the supporting rod 422 to adjust the position of the inserting hole of the supporting rod 422 corresponding to the other threaded hole of the fixing rod 424, and then the adjusting screw 426 is inserted from the inserting hole of the supporting rod 422 to be in threaded connection with the other threaded hole of the fixing rod 424. Meanwhile, the support rod 422 and the fixing rod 424 of the other fixing assembly in the symmetrical position are correspondingly operated, so that the height adjustment of the mounting bracket support column 420 is realized. In order to realize the firm and stable connection between the support rod 422 and the fixing rod 424, the aperture of the insertion hole of the support rod 422 may be slightly larger than the outer diameter of the adjusting screw 426.

In other embodiments, the support rod 422 may also be provided with a plurality of insertion holes, and the insertion holes may also be a threaded hole structure, and the fixing rod 424 may also be provided with more than two threaded holes, so as to provide more options for adjusting the height of the mounting bracket support column 420. In addition, in other embodiments, the support rod 422 may also have a threaded hole at a side opposite to the insertion hole, so that the adjusting screw 426 may pass through the insertion hole of the support rod 422 and the threaded hole of the fixing rod 424, and further be in threaded connection with the threaded hole at the other side of the support rod 422, thereby more firmly connecting the support rod 422 and the fixing rod 424 together. In addition, in some embodiments, the insertion holes of the support rods 422 may be replaced with threaded holes.

The temperature sensing assembly 500 includes a bracket 510, a temperature sensor 520, and a temperature sensor wire 530. The temperature sensor 520 is mounted on the bracket 510. The temperature sensor line 530 connects the temperature sensor 520 and the control board of the control box 300. The bracket 510 has a cover plate to achieve shielding of the temperature sensor 520 from direct sunlight. The bracket 510 should be installed at 1.5 meters outside the control box 300. The temperature sensor 520 detects the ambient temperature near the electronic target indicator 900 and generates a corresponding temperature signal, which is then transmitted to the control box 300 via the temperature sensor line 530.

The positional relationship of the target assembly 100 and the detection assembly 200 of the electronic target drone 900 may be chosen differently. As shown in fig. 6, in the present embodiment, the first sensor array 210 and the second sensor array 220 are disposed in front of the target board 110. In another embodiment, as shown in FIG. 7, the first sensor array 210 is disposed in front of the target board 110 and the second sensor array 220 is disposed behind the target board 110. In addition, in another embodiment, the first sensor array 210 and the second sensor array 220 may be disposed behind the target board 110. In other embodiments, the first sensor array 210 and the second sensor array 220 may be disposed on other sides of the target board 110, such as diagonally front and diagonally back.

According to the electronic target indicator 900 provided by the invention, the first sensor array 210 and the second sensor array 220 are sequentially arranged on at least one side of the target board 110, and the impact point coordinates are generated based on a preset rule according to the detection point coordinates of the first sensor array 210 and the second sensor array 220. Therefore, the electronic target-reporting device 900 can provide more accurate detection results, and meet the requirements of actual combat shooting training.

In other embodiments, the first sensors 212 are adjustable in spacing from each other and the second sensors 222 are adjustable in spacing from each other.
