[0002] Competition in the riflescope market is becoming increasingly fierce, and the requirements for the endurance of riflescopes are also increasing. At present, riflescopes mainly use disposable button batteries to provide power for the lighting device to illuminate the reticle. When the button battery is used up, it needs to be replaced. Since the reticle is large, the required lighting area is wide and the lighting brightness is high, the button battery consumes power quickly. Under normal circumstances, a button battery can only work for about a day under the brightest lighting, and the riflescope may suddenly go out when used in the field. If there is no spare battery, it will lead to the inability to aim at the target normally, which seriously affects the use. Summary of the invention

[0024] Reference Figures 1 to 3 A vibration power supply device of this embodiment includes a scope body 10, a sleeve 20, a coil 30 and a sliding cylindrical magnet 40. The vibration power supply device uses the cutting magnetic flux lines between the sliding cylindrical magnet 40 and the coil 30 to make the coil 30 have current to power the lighting device of the scope. It is worth noting that the vibration power supply device can not only power the lighting device, but also other electrical devices in the scope.

[0025] Among them, refer to Figure 1 The mirror body 10 is the mirror body of the sighting scope, which provides overall support for the vibration power supply device. The sleeve 20 is arranged on the mirror body 10, and the sleeve 20 has a cylindrical slide groove 21, and the sleeve 20 is made of plastic material. The coil 30 is arranged on the sleeve 20, and the coil 30 is a multi-clad copper coil. The sliding cylindrical magnet 40 can be freely slidably arranged in the slide groove 21. There is a gap between the sliding cylindrical magnet 40 and the slide groove 21 to facilitate the sliding of the sliding cylindrical magnet 40.

[0026] When the sight shakes with the firearm, the sliding cylindrical magnet 40 slides in the slide groove 21. At this time, the coil 30 moves relative to the sliding cylindrical magnet 40 to cut the magnetic flux lines, so that the coil 30 has current to supply power to the lighting device of the sight.

[0027] Further, refer to Figure 1 and Figure 2, the vibration power supply device also includes a buffer magnet 50. The buffer magnet 50 is arranged at the end of the slide groove 21, and the polarity of the opposite surfaces of the buffer magnet 50 and the sliding cylindrical magnet 40 is the same. For example, if the polarity of the buffer magnet 50 is SN, the sliding cylindrical magnet 40 is NS, so that the N pole of the buffer magnet 50 and the N pole of the sliding cylindrical magnet 40 are opposite. When the sliding cylindrical magnet 40 slides to the end of the slide groove 21, the N pole of the buffer magnet 50 will buffer the sliding of the sliding cylindrical magnet 40.

[0028] Preferably, there are two buffer magnets 50, and the two buffer magnets 50 are respectively arranged at both ends of the slide slot 21. That is, when the sliding cylindrical magnet 40 slides to either end of the slide slot 21, there is a buffer magnet 50 to buffer the sliding cylindrical magnet 40. Of course, it is not excluded that in some embodiments, there is only one end with a buffer magnet 50.

[0029] In this embodiment, the polarities of the two buffer magnets 50 and the sliding cylindrical magnet 40 are NS, SN, and NS, respectively, so as to buffer the sliding of the sliding cylindrical magnet 40 .

[0030] More preferably, the buffer magnet 50 is cylindrical, and the buffer magnet 50 is inserted at the end of the chute 21. The buffer magnet 50 is cylindrical so as to match the cylindrical shape of the chute 21. Of course, in some other embodiments, the buffer magnet 50 is not cylindrical, such as in a block shape. The block-shaped buffer magnet 50 is set at the end of the chute 21, which can also provide buffering for the sliding cylindrical magnet 40.

[0031] Further, refer to Figures 1 to 3 The sleeve 20 includes a first cylinder 22 and a second cylinder 23. The second cylinder 23 is arranged outside the first cylinder 22 and is arranged concentrically with the first cylinder 22. The interval between the first cylinder 22 and the second cylinder 23 forms a slide groove 21. In this embodiment, the sleeve 20 also includes a round bottom plate. The first cylinder 22 and the second cylinder 23 are both installed on the round bottom plate.

[0032] Preferably, the coil 30 is arranged on the outside of the second cylinder 23 and / or on the inside of the first cylinder 22. In this embodiment, there are two coils 30, one of which is sleeved on the outside of the second cylinder 23, and the other coil 30 is inserted inside the first cylinder 22. The two coils 30 can further increase the amount of power that can be supplied and ensure the long-term use of the lighting device. In some embodiments, there is only one coil 30 and it is arranged on the outside of the second cylinder 23 or on the inside of the first cylinder 22.

[0033] More preferably, refer to Figure 3The first cylinder 22 and / or the second cylinder 23 are provided with a cylindrical mounting groove 24. The cylindrical mounting groove 24 is used to mount the coil 30. In this embodiment, two coils 30 are provided, so the first cylinder 22 and the second cylinder 23 are both provided with a cylindrical mounting groove 24.

[0034] It should be noted that when there is only one coil 30, if the coil 30 is arranged outside the second cylinder 23, a cylindrical mounting groove 24 should be provided on the outside of the first cylinder 22. If the coil 30 is arranged inside the first cylinder 22, a cylindrical mounting groove 24 should be provided on the inside of the second cylinder 23.

[0035] Further, refer to Figure 1 The coil 30 is electrically connected to a rectifier circuit board 60, and the rectifier circuit board 60 is electrically connected to the lighting device 70 or a capacitor. After the current generated by the coil 30 is rectified and filtered by the rectifier circuit board 60, if the rectifier circuit board 60 is connected to the lighting device 70, the lighting device 70 is powered; if the rectifier circuit board 60 is electrically connected to the capacitor, the electric energy is stored in the capacitor for use.

[0036] Preferably, the rectifier circuit board 60 is electrically connected to a battery 80. The battery 80 is a button battery. The device is provided with a button battery, thereby realizing two forms of vibration power supply and battery power supply, ensuring the normal use of the lighting device.

[0037] A sighting scope of the present embodiment includes any one of the vibration power supply devices described above. The sighting scope utilizes the movement of the cutting magnetic flux lines between the sliding cylindrical magnet 40 and the coil 30 in the vibration power supply device to make the coil 30 generate current, which is rectified by the rectifier circuit board to power the lighting device of the sighting scope, and the current can also be stored in a capacitor.

All technologies realized based on the above contents belong to the scope of the present invention.
