In order to make the above purposes, features and advantages of the present disclosure more comprehensible, the present disclosure is further and in detail described combining with the accompanying drawings and specific embodiments thereof
As shown in
In some embodiments, the assembly for fixing and moving bow and arrow includes a locking mechanism 4, a level adjustment mechanism 6, a height adjustment mechanism 5 and a guide rail 3. The locking mechanism 4 is slidably disposed at one end of the guide rail 3 and is configured for fixing the bow and arrow. One end of the height adjustment mechanism 5 is connected to the other end of the guide rail, and the other end of the height adjustment mechanism 5 is connected to the level adjustment mechanism 6. The locking mechanism 4 includes connecting holes 41 and a locking button 42.
The locking mechanism 4 may be locked by the locking button 42 after sliding along the guide rail 3 forth and back to an appropriate position, which can be adjusted by an archer into a comfortable condition according to a size of the bow and arrow and personal conditions, mainly satisfying the distance between eyes and an aiming reticle. The height adjustment mechanism 5 is rotated for observing side scale points and the arrow markings to preliminarily achieve an approximate aiming, and the level adjustment mechanism 6 is adjusted to achieve the level adjustment. The height adjustment mechanism and the level adjustment mechanism are both threaded screw mechanisms, and a difference is that the mechanisms are not disengaged during rotation of screws by using snap and key limits, while movement gaps are eliminated. The height adjustment mechanism 5 is configured to satisfy the left-right interchange of the whole module in the front of the height adjustment mechanism, while ensuring that the adjustment mechanism in the rear of the height adjustment mechanism is unchanged.
The mounting seat for distance measuring and aiming module 1 is further provided with a power supply module 10. The power supply module 10 is a main switching power supply, and can be performed modes switching (between manual mode and automatic mode) and excite laser for distance measuring (automatic distance measuring for 60 seconds since starting up, and standby in case of no action after 60 seconds).
The mounting seat for distance measuring and aiming module 1 is further provided with an adjustment button 11. The aiming point may be adjusted manually through the upper and lower keys of the adjustment button. The upper and lower keys are pressed for 5 seconds simultaneously to store memory, and then restore to the factory state.
The mounting seat for distance measuring and aiming module 1 is further provided with a Type-c charging port 12. If the electronic reticle display screen 8 displays a power shortage status when the device is short of capacity, the device can be charged by the archer through the Type-c charging port 12, and a large-capacity rechargeable lithium battery is disposed in the device.
The traction switch 13 is detachably connected to the charging port 12. The traction switch 13 may be configured to satisfy the operation requirements of different archers, extend for 50-80 cm, have an adhesive tape, and be conveniently placed in the conventional operation position of the archer. The traction switch 13 may excite the laser for distance measuring beyond visual range, since the laser rangefinder is in a standby state after the laser rangefinder is not operated for 1 minute, and the laser needs to be excited once to operate the laser rangefinder.
The mounting seat for distance measuring and aiming module 1 is further provided with an indicating laser 14, which has the function of quickly correcting the aiming point and directly indicating a target fast shoot. The zero-position aiming point on the electronic reticle display screen 8 observed by a human eye is collinear with an indication point of the indicating laser 14.
The device includes two working modes: the manual mode and the automatic mode.
In the manually mode: two holes of the connecting holes 41 are connected to a bow body of the bow, and another two holes of the connecting holes 41 may be connected to a quiver. After having been connected, the connecting holes 41 are released, the distance between the human eye and the electronic reticle display screen 8 is adjusted to be optimal, and then is locked by the locking mechanism 4, thereby achieving a relationship between the sight and the bow and arrow. The height adjustment mechanism 5 is rotated to complete the upper and lower quick alignment of the sight with targets, and the level adjustment mechanism 6 is rotated to complete the left and right quick alignment with targets. The aiming at the zero position is realized by quick adjustment and calibration. The zero position reference is that the level meter 9 reaches a horizontal position, and the human eye, the zero position aiming point (adjusted by the adjustment button 11) on the display screen 8 and the target form a straight line, thus the final object is achieved through such an adjustment and calibration. When the bow is full, the arrow can accurately fall on the aiming point after being released.
In the automatic mode: repeating the above operations, five main aiming points on the electronic reticle display screen 8 are successively calibrated according to the distance and angle values displayed on the electronic reticle display screen 8, and the memory is stored by pressing the adjustment button 11 and the power supply module 10, and then the aiming point is automatically calculated by a shooting processing module according to the distance. In particular, the bubble of the level meter 9 remain horizontal at zero position, the angle displayed on the electronic reticle display screen 8 is 0 degree. The corrected angle value is a positive angle value (elevation) when the aiming point lies below zero; and the corrected angle value is a negative angle value (dipping) when the aiming point lies above zero.
The calculating principle of the processing module is shown in
Secondly, the shooting table of the bow and arrow is provided, i. e. the database compiled from the accuracy of the same standard arrow shaft and arrow head in a statistical probability method per bow and arrow for different distances. The processing module determines to light the aiming point on the electronic reticle display screen 8 by calculating the distance and angle of the target. When the influence of air on the speed of the arrow is not considered, the shooting angle Ψ is calculated from the following formula: s=(2 sin Ψ*cos Ψ*V2)/g, and the speed component V1=V*cos Ψ of the initial speed V in the vertical direction is calculated first. The flight time T=V1/g of the arrow in the air is calculated, and the horizontal distance S is equal to the product of the horizontal speed component V2=V*sin Ψ and the flight time T.
S=V2*T; and
g is gravitational acceleration.
There are different positions on the target in the vertical direction, and the adjustment of the aiming point can also be reversed and realized through angle compensation. The angle herein refers to the included angle between the horizontal position indicated by the level meter (the angle value displayed on the electronic reticle display screen 8 is 0) and the arrow shaft. The algorithm is expressed in terms of the aiming point displayed by the electronic reticle display screen 8, based on which the archer is directly guided to aim the target. Furthermore, the target moves within a range of ±1 meter, the aiming point does not change quickly, and only when the target moves quickly, the archer tracks the target aiming point to change with the movement speed and distance. Once the target stops, the aiming point is accurately indicated according to the distance parameter, so as to ensure that the archer can shoot the arrow at any time.
Moreover, in order to suitable to the tactical requirements, the processing module has a learning function, i. e. the archer can accurately calibrate the 20 yards, 30 yards, . . . , 60 yards according to the usage habits, and store each calibrated point by pressing the saving key. The processing module can accurately display the corresponding shooting aiming point according to different distances so as to achieve the tactical effect of hundreds of transmission.
The present disclosure is designed symmetrically up and down, and can achieve an aiming system (the electronic reticle is reversible to display) for left and right hand switching. Since the display information on the electronic reticle display screen 8 is an electronic number, the symmetric display may be reversed at any time according to the software setting, and this function can be realized by shortly pressing the power supply modules 10 twice, thereby bringing convenience to the left and right hands habits.
In addition, the aiming device provided by the present disclosure can be applied not only to the aiming of a bow and arrow, but also to a crossbow or a gun.
Various embodiments in the present description are described in a progressive manner, and the emphasizing description of each embodiment is different from the other embodiments, and the same similar parts between various embodiments can be referred to for each other.
The principle and the implementation mode of the present disclosure are explained by using specific examples in the present specification, and the above description of the embodiments is only used to help understand the method and the core idea of the present disclosure; meanwhile, for a person skilled in the art, it may be changed in the specific embodiments and the application range according to the idea of the present disclosure. In conclusion, the contents of the description should not be construed as limitations on the disclosure.
