Description
Technical Field
[0001] The utility model belongs to the technical field of shooting training equipment, and particularly relates to an electronic aiming inspection mirror for QBZ191 automatic rifle. Background Art
[0002] During shooting training, the inspection mirror, as an important auxiliary instrument for instructors to observe the shooting and aiming postures of trainees, is usually installed on the Picatinny rail in front of the gun sight. By looking through the windows in front of and behind the inspection mirror and aiming in the normal way, the scenes of the shooter's sighting aperture, front sight and target, etc. are reflected to the inspection port on the right side of the inspection mirror through the 45-degree inclined reflective glass inside the inspection mirror. The instructor is on the right side of the shooter and needs to be almost face-to-face at a very close distance to observe the trainee's aiming situation from the inspection port on the right side of the inspection mirror. This operation has the following deficiencies:
[0003] First, the almost zero-distance contact greatly affects the shooter's aiming posture, thus affecting the training effect, and may also cause respiratory cross-infection during special periods.
[0004] Second, during outdoor training in low temperatures, since the instructor needs to get close to the inspection mirror to observe the trainee's aiming scene from the inspection port, the exhaled breath at close range will cause the surface of the reflective mirror to fog up, thus affecting the normal aiming training and guidance of the instructor and the trainee.
[0005] Third, when the instructor checks the trainee's training situation through the traditional inspection mirror for a long time, visual and neck and shoulder muscle fatigue will occur, the inspection efficiency is low, and it is time-consuming and laborious. Content of the Utility Model
[0006] The purpose of the utility model is to provide an electronic aiming inspection mirror for QBZ191 automatic rifle to solve the above problems existing in the prior art.
[0007] To achieve the above purpose, the utility model adopts the following technical solutions:
[0008] The electronic aiming inspection mirror for QBZ191 automatic rifle includes a bracket unit, a fixed seat, an observation frame, a camera mounting bracket and an electronic imaging unit. Among them, the electronic imaging unit is composed of a camera lens and a USB high-definition imaging module.
[0009] Furthermore, the fixed seat is composed of a first clamping block and a second clamping block, and the fixed seat is detachably installed at the bottom of the side platform on one side of the front end of the bracket unit.
[0010] Furthermore, the observation frame is fixed on one side of the rear end of the bracket unit, and a real-time scene mapping prism is installed inside the observation frame. The real-time scene mapping prism adopts a four-sided anti-reflection type dichroic prism. Compared with the dichroic effect of a traditional plane dichroic reflector, the scene refracted by the four-sided anti-reflection type dichroic prism has higher clarity. In order to make the inspection mirror suitable for the QBZ191 automatic rifle, the height of the center position of the real-time scene mapping prism is 32.5 mm.
[0011] Furthermore, the camera mounting bracket is arranged at the rear end of the bracket unit, and the inner side of the camera mounting bracket is connected with one side of the observation frame, the camera lens is installed on the inner side of the camera mounting bracket, and the USB high-definition camera module is installed at the rear end of the camera mounting bracket.
[0012] Furthermore, the camera lens adopts a large depth of field machine vision industrial lens with a lens fine-tuning knob and an exposure adjuster. The camera lens is preferably a 1.8-inch 16㎜ fixed-focus industrial large depth of field lens. The camera mounting bracket is provided with a notch corresponding to the position of the lens fine-tuning knob and the exposure adjuster on the camera lens. The notch is provided to facilitate instructors to adjust the camera lens angle according to the structure of different models of firearms to ensure the clarity of image acquisition.
[0013] Furthermore, the rear end of the camera lens is assembled and connected to the lens mounting seat on the USB high-definition camera module, and the USB data output port integrated on the USB high-definition camera module is connected to an external display terminal via a USB wire.
[0014] Furthermore, the bracket unit is composed of a connecting rod, an inspection mirror bracket and an auxiliary arm, and the front ends of the connecting rod, the inspection mirror bracket and the auxiliary arm are integrally connected, the auxiliary arm is located on the side of the connecting rod, and the rear end of the auxiliary arm is connected to the rear end of the camera mounting bracket, and the camera mounting bracket is fixed to the rear end of the inspection mirror bracket, and the side platform and the observation frame are respectively fixed on the same side positions of the front and rear ends of the connecting rod. The design of the entire bracket unit constitutes a structure that approximates a triangular pyramid, which can effectively improve the stability of the overall structure of the inspection mirror.
[0015] Furthermore, the No. 1 clamping block is connected to the side platform via a No. 1 bolt, and the No. 2 clamping block is installed on the No. 1 clamping block via a No. 2 bolt.
[0016] Beneficial effects:
[0017] The utility model makes an improved design on the structure of the traditional inspection mirror. A four-sided antireflection beam splitter prism is used to divide the scene mapped in the observation hole inside the observation frame into two parts. One part of the scene passes through the real-time situation mapping prism along the original path and is observed by the trainee with the eyes for training. The other part of the scene is captured by the photosensitive imaging component in the USB high-definition camera module through the mapping of the beam splitter prism and then passes through the camera lens. Finally, after being processed by the chip integrated on the USB high-definition camera module, it is transmitted to an external display terminal through a USB data cable for display. When the inspection mirror for shooting training after the improved design is in use, the observation line of sight of the shooter can be intuitively shared through the display terminal. There is no need for the instructor to be in close contact with the inspection mirror, so there will be no phenomenon of visual and neck and shoulder muscle fatigue, and it will not cause interference to the shooting posture training of the trainee. It can not only improve the effect of the trainee's shooting training, but also reduce the risk of respiratory cross-infection. Moreover, due to the fact that the improved inspection mirror does not require the instructor to observe at close range, it can effectively avoid phenomena such as fog, polarization, and glare, and the imaging effect is clearer and more intuitive.

[0022] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the present utility model in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings. It should be noted here that the description of these embodiment modes is used to help understand the present utility model, but does not constitute a limitation to the present utility model.
[0023] Embodiment:
[0024] As Figures 1-4As shown, this embodiment provides a QBZ191 type automatic rifle electronic aiming inspection scope, including a bracket unit 1, a fixing seat, an observation frame 7, a camera mounting bracket 8 and an electronic camera unit, wherein the electronic camera unit is composed of a camera lens 9 and a USB high-definition camera module 11.
[0025] like Figure 1 As shown, the fixing seat is composed of a No. 1 clamp block 4 and a No. 2 clamp block 6, and the fixing seat is detachably installed at the bottom of the side platform 2 on the front side of the bracket unit 1; the main purpose of the fixing seat is to fix the entire inspection mirror device to the Picatinny rail 14.
[0026] The observation frame 7 is fixed on one side of the rear end of the bracket unit 1. In order not to affect the trainees' aiming, shooting and observing the target, and to be able to share the trainees' line of sight in real time through the observation mirror, a real-time scene mapping prism 10 is installed inside the observation frame 7. The real-time scene mapping prism 10 adopts a four-sided anti-reflection type dichroic prism. Compared with the dichroic effect of a traditional plane dichroic reflector, the scene refracted by the four-sided anti-reflection type dichroic prism has higher clarity.
[0027] In order to make the inspection mirror suitable for the QBZ191 automatic rifle, the height of the center position of the real-time scene mapping prism 10 is 32.5 mm.
[0028] like Figure 2 As shown, in order to enable the electronic camera unit to smoothly capture the real-time scene observed by the trainee when shooting and aiming from the real-time scene mapping prism 10, the camera mounting bracket 8 is set at the rear end of the bracket unit 1, and the inner side of the camera mounting bracket 8 is connected with one side of the observation frame 7, and the camera lens 9 is installed on the inner side of the camera mounting bracket 8, and the USB high-definition camera module 11 is installed at the rear end of the camera mounting bracket 8.
[0029] The camera lens 9 adopts a large depth of field machine vision industrial lens with a lens fine-tuning knob 12 and an exposure adjuster 13. The camera lens 9 is preferably a 1.8-inch 16㎜ fixed-focus large depth of field industrial lens. A notch is provided on the camera mounting bracket 8 corresponding to the position of the lens fine-tuning knob 12 and the exposure adjuster 13 on the camera lens 9. The notch is provided to facilitate the instructor to adjust the angle of the camera lens 9 according to the structure of different models of firearms to ensure the clarity of image acquisition.
[0030] In order to enable the USB high-definition camera module 11 to successfully capture the scene refracted by the real-time scene mapping prism 10 through the camera lens 9 , the rear end of the camera lens 9 is assembled and connected to the lens mounting seat on the USB high-definition camera module 11 .
[0031] Meanwhile, to facilitate the instructor's observation of the aiming line of sight during the trainee's shooting training, the USB data output port integrated on the USB high-definition camera module 11 is connected to an external display terminal (not shown) through a USB wire (not shown).
[0032] As Figures 1-2 shown, to improve the stability of the entire inspection mirror structure, its bracket unit 1 is composed of a connecting rod 101, an inspection mirror bracket 102, and an auxiliary arm 103. The front ends of the connecting rod 101, the inspection mirror bracket 102, and the auxiliary arm 103 are integrally connected. The auxiliary arm 103 is located on the side of the connecting rod 101, and the tail end of the auxiliary arm 103 is connected to the tail end of the camera mounting bracket 8. The camera mounting bracket 8 is fixed to the tail end of the inspection mirror bracket 102. The side platform 2 and the observation frame 7 are respectively fixed at the same-side positions at the front and rear ends of the connecting rod 101. The design of the entire bracket unit 1 constitutes a structure similar to a triangular pyramid, which can effectively improve the stability of the overall structure of the inspection mirror.
[0033] To make the installation of the device more convenient, its first clamping block 4 is connected to the side platform 2 through a first bolt 3, and the second clamping block 6 is installed on the first clamping block 4 through a second bolt 5. When installing the inspection mirror, only need to loosen the second clamping block 6, buckle the fixing seat on the Picatinny rail 14, and then tighten the second bolt 5 to complete the installation of the inspection mirror.
[0034] During the use after the inspection mirror is installed, a four-sided antireflection spectroscope prism is used to divide the scene mapped in the observation hole inside the observation frame 7 into two parts. One part of the scene passes through the real-time scene mapping prism 10 along the original path and is observed by the trainee with eyes for training. The other part of the scene is captured by the photosensitive imaging component in the USB high-definition camera module 11 through the mapping of the spectroscope prism and then passes through the camera lens 9, and finally, after being processed by the chip integrated on the USB high-definition camera module 11, it is transmitted to an external display terminal through a USB data cable for display. It should be noted that: the USB high-definition camera module 11 and the camera lens 9 described in the text are both relatively mature technical products at present and belong to the existing well-known technologies. Therefore, the structural design and working principle of the USB high-definition camera module 11 and the camera lens 9 (i.e., the large-depth-of-field machine vision industrial lens) are not described in detail in the text.
[0035] After the improved design of the inspection mirror for shooting training, during use, the shooter's observation line of sight can be intuitively shared through the display terminal, which can not only improve the effect of the trainee's shooting training, but also reduce the risk of respiratory cross-infection. At the same time, it can effectively avoid phenomena such as fog, polarization, and glare, and the imaging effect is clearer and more intuitive compared with the traditional inspection mirror device.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
