[0048] As shown in FIGS. 1-5, the infrared sighting device of the present embodiment has a front end near the object side when used with an infrared sighting device, and a rear end near the eye side. The infrared sighting device comprises a housing 1, an infrared assembly 2 movably mounted at the front end of the housing 1 for converting optical signals into electrical signals, a damping member 4 provided between the infrared assembly 2 and the housing 1, a main control unit 5 mounted in the housing 1 and electrically connected to the infrared assembly 2 for obtaining the electrical signals output by the infrared assembly 2, and a display screen 3 mounted at the rear end of the housing 1 and electrically connected to the main control unit 5 for displaying infrared images.

[0049] The infrared sighting device of the embodiment can be used for infrared imaging in multiple scenes, and the embodiment is described by taking the use for pistol sighting as an example. The damping member 4 is an O-shaped sealing ring, which is sleeved on the infrared assembly 2, and the infrared assembly 2 is movably mounted on the shell 1. When the pistol is fired, the infrared assembly 2 moves relative to the shell 1 due to the recoil force, and the O-shaped sealing ring is compressed and deformed to achieve damping and maintain imaging stability. At the same time, the infrared assembly 2 and the shell 1 are prevented from colliding to prolong the service life. In addition, the infrared assembly 2 is relatively fixed as a whole, and the damping is achieved between the infrared assembly 2 and the shell 1. On the one hand, the relative position of the internal elements of the infrared assembly 2 is stable, and the stability of the imaging effect is further improved. On the other hand, only one damping member 4 is arranged between the infrared assembly 2 and the shell 1, and no additional damping structure is needed, thereby further reducing the volume of the infrared sighting device, and the infrared sighting device can be applied to small guns such as pistols.

[0050] In some embodiments, the display screen 3 is a touch display screen, which supports the user to control the infrared sighting device to calibrate the gun and realize electronic zooming while displaying the infrared image, and the touch display screen 3 can also control all functions of the infrared sighting device. The data line interface 52 is arranged on the main control unit 5, which is a TYPE-C interface in the embodiment. The data line interface 52 can be used for charging or data transmission by plugging a data line. The shell 1 is provided with a data line interface cover plate 24 for protecting the TYPE-C interface at the corresponding position of the data line interface 52.

[0051] In the embodiment, the infrared assembly 2 converts the light signals of the aiming area into electrical signals and outputs the electrical signals to the main control unit 5. The main control unit 5 processes the electrical signals and displays the infrared image through the display screen 3. The user can directly observe the infrared image through the display screen 3, and the setting of the eyepiece can be omitted, so that the infrared sighting device is lighter and smaller, and can be better adapted to small guns such as pistols. In addition, the infrared sighting device can reduce vibration by arranging the damping member 4 between the infrared assembly 2 and the shell 1, which is conducive to maintaining the imaging stability and further reducing the volume of the infrared sighting device.

[0052] In a possible embodiment, the infrared assembly 2 includes an infrared objective lens 21, a core flange 22, and an infrared detector 23. The infrared objective lens 21 is mounted on one end of the core flange 22, and the infrared detector 23 is mounted on the other end of the core flange 22 away from the infrared objective lens 21. The infrared detector 23 is electrically connected to the main control unit 5, and the damping member 4 is clamped between the infrared objective lens 21 and the shell 1.

In this embodiment, the infrared objective 21, the core flange 22 and the infrared detector 23 are connected to form an integral whole, the inside of the integral whole is relatively fixed, and the integral whole is provided with the damping member 4 between the housing 1; the main control unit 5 further includes a circuit board 51 and a control unit arranged on the circuit board. The control unit can be a control chip such as a CPU, a GPU or an MCU. The control chip is electrically connected to the infrared detector 23. The infrared detector 23 can convert an infrared light signal into an electric signal. After the control chip acquires the electric signal, a video signal is output to enable the display screen 3 to display an infrared image.

[0054] In a possible embodiment, the housing 1 includes a main housing 11 and a front shell 12 detachably connected to the main housing 11. The infrared objective 21 penetrates the front shell 12 to be connected to the core flange 22.

The damping member 4 is arranged between the infrared objective 21 and the front shell 12.

[0055] It can be understood that the shape of the front shell 12 is matched with the shape of the infrared objective 21. The infrared objective 21 is arranged in the front shell 12 and penetrates the front shell 12 to be threadedly connected to the core flange 22. After the infrared objective 21 is focused, it is locked to enable the infrared objective 21, the core flange 22 and the infrared detector 23 to form an integral whole. The relative position of the infrared objective 21 and the infrared detector 23 is kept fixed. Changes in the distance between the infrared objective 21 and the infrared detector 23 caused by vibration can be avoided. The light passing through the infrared objective 21 can be stably imaged on the infrared detector 23. The infrared assembly 2 and the housing 1 are in a relative movement relationship instead of a locked relationship. The damping member 4 is arranged on the relative movement path of the infrared objective 21 and the front shell 12. Therefore, the damping member 4 can be compressed when the integral whole of the infrared assembly 2 relatively moves with respect to the front shell 12. The damping effect can be achieved.

[0056] In a possible embodiment, the housing 1 is provided with a mounting member 31 at the rear end. The touch display screen 3 is mounted on the mounting member 31. The mounting member 31 is provided with a light window 311 through which light can pass.

The mounting member 31 is a plate body that is consistent with the shape of the end of the housing 1. The light window 311 is transparent glass that can allow light to pass through and prevent foreign matters from entering the housing 1. In other embodiments, the light window 311 can be a through hole. A protective net is arranged in the through hole to prevent foreign matters from entering while not affecting the light passing through.

[0058] In a possible embodiment, the infrared sighting device further comprises an ambient light sensor 6 arranged in the shell 1, the sensing end of the ambient light sensor 6 is opposite the light window 311, and the ambient light sensor 6 is electrically connected to the main control unit 5.

[0059] The ambient light sensor 6 obtains ambient light intensity through light entering through the light window 311 and transmits the ambient light intensity to the main control unit 5, and the main control unit 5 can automatically adjust the brightness of the touch display screen 3 according to the ambient light intensity, so that the user can more conveniently observe the screen, and the infrared sighting device can be more concealed and not easily discovered by the target.

[0060] In a possible embodiment, the shell 1 further comprises a button 13 arranged on one side of the shell 1, and the button 13 is electrically connected to the main control unit 5.

[0061] It can be understood that the number of the button 13 needs to realize all functions of the infrared sighting device, and in special cases, for example, when the touch function of the touch display screen 3 fails, all functions of the infrared sighting device can be controlled through the button 13.

[0062] In a possible embodiment, the shell 1 further comprises a battery compartment 14 for mounting a battery, and the battery compartment 14 is provided with a battery compartment cover 141.

[0063] The battery compartment 14 stores a battery for supplying power to the infrared sighting device, and the battery in the embodiment is a rechargeable reusable battery, for example, a lithium battery. The reusable battery can be charged through a type-c interface connected to a type-c data line. In other embodiments, the battery can also be a disposable battery, which can be replaced by opening the battery compartment cover 141, which is more convenient for replacement. The battery compartment cover 141 is arranged on the shell 1, and the battery can be taken out or placed in by opening the battery compartment cover 141, which is fast and convenient.

[0064] In a possible embodiment, the shell 1 further comprises a mechanical aiming point 15, which can assist the mechanical aiming of the shooting equipment in special cases, for example, when the battery power is exhausted or the infrared sighting device is abnormal.

[0065] The infrared sighting device provided by the above-mentioned embodiments has at least the following characteristics:
