In this arrangement, the pressing ring 136 substantially covers the base 139, so that only a part of the base 139 is exposed from the opening 363, the adjustment screw 135 passes through the through hole 393 of the base 139 and abuts against the inner barrel, and the pin 759 abuts against one of the grooves 381 of the ring gear 138 by the restoring force generated by the deformation of the elastic member 757. When the transmission unit 137 rotates, the pins 759 are driven to move between the grooves 381, so that a click sound is generated to provide feedback to the user.
As shown in fig. 1, the driving unit 133 is used for driving the transmission unit 137 to rotate by the clutch 134, and includes a motor 333, a rotating shaft 335 and a transmission gear 331. Specifically, the motor 333 is disposed on the body 11, the rotating shaft 335 is disposed at the center of the motor 333, and the transmission gear 331 is connected to the motor 333 via the rotating shaft 335, disposed in the opening 363 of the pressing ring 136, and engaged with the transmission gear ring 345 on the clutch 134. After the driving unit 133, the clutch 134, the transmission unit 137, the adjusting screw 135 and the base 139 are assembled, the L-shaped outer cover 143 is disposed on the body 11 by two screws 431, substantially covers the driving unit 133, the clutch 134, the transmission unit 137 and the base 139, and only exposes the top of the socket 371 and the L-shaped ring 347 of the clutch 134.
The scale ring 132 is sleeved on a portion of the outer cover 143 corresponding to the transmission unit 137 to prompt a user of an adjustment amount of the compensation device 13. The upper cover 140 has a V-shaped groove 401 provided to the L-shaped ring 347 of the clutch member 134 and covers the socket 371. Finally, the screw 311 passes through the adjustment cap 131 and abuts against the V-shaped groove 401 of the upper cap 140, so that the adjustment cap 131 is connected to the clutch 134 and the transmission unit 137, thereby completing the assembly of the sight 100.
The operation of the compensating device 13 in the automatic operation mode will be explained next. In the automatic operation mode, the adjustment cover 131 is positioned in the first position. As shown in fig. 1, when the adjusting cover 131 is located at the first position, the clutch 134 is located at the third position relative to the first cylinder 373, the L-shaped ring 347 abuts against the end portion of the first cylinder 373 provided with the seat 371, the ball 735 is engaged with the first annular groove 341 of the clutch 134, and the transmission gear 331 of the driving unit 133 is engaged with the transmission gear ring 345 of the clutch 134. By engaging the transmission gear 331 with the transmission gear ring 345, the power generated by the operation of the motor 333 is transmitted to the adjustment cover 131 and the transmission unit 137, so that the adjustment cover 131 and the transmission unit 137 rotate. Subsequently, due to the rotation of the adjusting cover 131 and the transmission unit 137, the adjusting screw 135 moves axially relative to the base 139, and the inner barrel moves to adjust the optical axis L.
If the user wants to switch the compensating device 13 from the automatic operation mode to the manual operation mode, the user only needs to pull the adjusting cover 131 upward and position the adjusting cover at the second position. As shown in fig. 2, when the adjusting cover 131 is located at the second position, the clutch 134 is located at the fourth position relative to the first cylinder 373, the L-shaped ring 347 is disengaged from the first cylinder 373, the ball 735 is engaged with the second annular groove 343 of the clutch 134, and the transmission gear 331 of the driving unit 133 is also disengaged from the transmission gear ring 345 of the clutch 134. It can be understood that since the driving gear 331 of the driving unit 133 is not engaged with the driving gear ring 345 of the clutch 134, the power generated by the operation of the motor 333 cannot be transmitted to the adjustment cover 131 and the driving unit 137. At this time, the user can manually rotate the adjusting cover 131, and the rotation of the adjusting cover 131 drives the transmission unit 137 to rotate, so that the adjusting screw 135 axially moves relative to the base 139, and further the inner barrel moves to adjust the optical axis L.
A sensor (not shown) may be further provided to detect an actual axial movement amount or a rotation angle of the adjusting screw 135, or the sensor may also be used to detect a rotation amount of the driving unit 133, and the driving unit 133 may be a stepping motor or a voice coil motor, so that the actual axial movement amount or the rotation angle of the adjusting screw 135 can be calculated by knowing the rotation amount of the driving motor; such as but not limited to an electromagnetic induction component. Referring to fig. 3, the dashed line at the bottom of the adjusting screw 135 is an illustration of an electrical wire 135a, and if the sensor is subsequently disposed on the adjusting screw 135, the sensor can be operated by the electrical wire 135 a.
In addition, in order to separate the clutch 134 from the driving unit 137, in addition to moving the clutch 134 along the axial direction of the adjusting screw, another embodiment of the present invention is to operatively move the driving unit 137 along a direction perpendicular to the axial direction of the adjusting screw 135 to approach or separate from the clutch 134, so as to operatively engage or disengage the driving unit with the clutch 134, wherein the manner of operatively engaging or disengaging the driving unit with the clutch 134 may be the movement of the entire driving unit 137 or only the rotating shaft 335 of the driving unit 137.
The sight 100 of the present invention not only enables automated operation of the compensating device, but also retains a manual mode of operation, and the user can simply adjust the position of the adjustment cap 131 to switch the mode of operation of the compensating device 13 according to his own needs for the mode of operation. The sight 100 of the present invention is more convenient and versatile in use than conventional sights. Furthermore, the automatically operable compensation means 13 further contribute to the development of remote control and collimator digitization.
