[0031] See also Figure 1 and Figure 2 The vehicle-mounted infrared pan-tilt device of an embodiment of the present application includes a horizontal rotation component 5, a pitch rotation component, a support component 3, a receiving frame 9, a thermal imager 2 and at least one functional component, and may also include a fixing seat 6 and a base mounting bracket 7.

[0032] The thermal imager 2 and the functional components are respectively arranged in the accommodating frame 9. One side wall of the accommodating frame 9 is rotatably connected to the supporting assembly 3 through the pitch rotation assembly. The bottom of the supporting assembly 3 is connected to the horizontal rotation assembly 5. The horizontal rotation assembly 5 is used to drive the accommodating frame 9 to rotate in the horizontal direction, and the pitch rotation assembly is used to drive the accommodating frame 9 to rotate in the vertical direction.

[0033] In some embodiments, the functional components include a laser rangefinder 13. The end of the lens 22 of the thermal imager 2 is provided with an end cap 23, which seals a side opening of the housing frame 9. A rangefinder window 1 is provided at the top of the housing frame 9, oriented in the same direction as the lens 22 of the thermal imager 2. This window 1 serves as an optical path for the laser rangefinder 13. Specifically, in this embodiment, the housing frame 9 has openings on the front, back, and top. Its bottom is closed, and its sides have mounting holes for connection to the support assembly 3. The front opening is for receiving the lens 22 of the thermal imager 2. An end cap 23 is fixed to the outer wall of the lens 22 of the thermal imager 2. This end cap 23 covers the front opening of the housing frame 9 and provides a seal. The integrated design of the thermal imager 2 and the end cap 23 of the housing frame 9 allows for a smaller size, which in turn reduces the overall size of the vehicle-mounted infrared pan / tilt device, saving space required for separate mating components. In this embodiment, the thermal imager 2 uses a large 25mm lens 22, which allows the vehicle-mounted infrared pan-tilt device to detect farther distances. The opening at the rear of the accommodating frame 9 is closed by a removable rear cover 91. The top opening is used to install the ranging window 1 of the laser rangefinder 13. The ranging window 1 closes the top opening. The opening direction of the ranging window 1 is consistent with the direction of the lens 22 of the thermal imager 2, and the ranging window 1 is located above the lens 22 of the thermal imager 2. The laser rangefinder 13 itself is miniaturized and installed on the upper part of the accommodating frame 9, which not only saves space in the accommodating frame 9 but also ensures a full range of distance measurement. The small laser rangefinder 13 used in this embodiment can measure a distance of about 1200 meters.

[0034] In order to further enhance the function of the vehicle-mounted infrared pan-tilt device, a laser pointer 14 as a functional component can also be set in the receiving frame 9. Figure 5 As shown, the functional assembly may include only the laser pointer 14; or, as shown Figure 1 As shown, the functional assembly includes both a laser rangefinder 13 and a laser pointer 14; alternatively, the functional assembly may include only the laser rangefinder 13, with the specific selection and configuration depending on actual needs. The end cap 23 also includes a laser pointer window 21, located between the lens 22 and the rangefinder window 1. In this embodiment, the laser pointer 14 is fixed to the core of the thermal imager 2. The light beam emitted by the laser pointer 14 is directly aligned with the laser pointer window 21 and can be emitted directly from the laser pointer window 21, saving space for a separate optical path structure.

[0035] In this embodiment, the horizontal rotation assembly 5 is used to drive the receiving frame 9 to rotate continuously 360 degrees in the horizontal direction; the pitch rotation assembly is used to drive the receiving frame 9 to rotate back and forth within a range of 180 degrees in the vertical direction. In other words, the pitch rotation assembly is used to drive the receiving frame 9 to rotate in the vertical direction, and the rotation angle is within the range of ±90 degrees relative to the horizontal plane. The vehicle-mounted infrared pan-tilt device of this embodiment has a rotation angle in the horizontal and vertical directions that can basically achieve target capture and tracking functions within the entire field of view.

[0036] The pitch rotation assembly includes a first motor 10, the rotor of which is directly fixedly connected to the containing frame 9. For example, the rotor of the first motor 10 and the side wall of the containing frame 9 can be connected by screws or other connecting parts. This can reduce the number of transmission devices, thereby improving transmission efficiency and reducing the size of the assembly. The support assembly 3 includes side frames 31 located on both sides of the containing frame 9 and a chassis 32 located at the bottom of the containing frame 9. The side frames 31 are fixedly connected to the chassis 32 respectively. One side wall of the containing frame 9 is rotatably connected to the corresponding side frame 31 through the first motor 10. That is, the first motor 10 is arranged on one side of the containing frame 9 to form a single cantilever structure with unilateral coaxial adjustment. The stator of the first motor 10 is fixed to the side frame 31. A dynamic seal is used between the rotor of the first motor 10 and the mounting groove of the side frame 31 for mounting the first motor 10. For example, an oil seal can be used to improve the waterproof performance of the vehicle-mounted infrared pan-tilt device. A first control circuit board may also be provided on the side frame 31 . The first control circuit board is provided with a first controller. The first controller is electrically connected to the first motor 10 and is used to control the rotation angle and rotation speed of the first motor 10 .

[0037] The horizontal rotation assembly 5 includes a second motor 51, the rotor of which is directly fixedly connected to the chassis 32. The rotor of the second motor 51 is directly connected to the chassis 32, while its stator is directly fixedly connected to the mounting base 6 via connectors. This design reduces the number of transmission devices, improves transmission efficiency, and reduces the overall size and weight of the vehicle-mounted infrared pan-tilt device. The rotor of the second motor 51 is detachably connected to the chassis 32 via multiple connectors, evenly distributed along the circumference of the chassis 32. The multiple connectors are used to connect the chassis 32, and the coaxiality between the chassis 32 and the second motor 51 can be adjusted by adjusting the tightness of the connection. The connectors can be, for example, screws. In this embodiment, there are four screws, evenly distributed around the circumference of the chassis 32. Adjusting the tightness of the screws with the chassis 32 adjusts the coaxiality. Improved coaxiality reduces friction during the rotation of the second motor 51, making the friction evenly distributed. Compared to traditional gear transmission structures, the direct connection structure of this embodiment reduces space waste. Compared to traditional belt transmissions, the direct connection structure of this embodiment improves transmission accuracy.

[0038] like Figure 3As shown, the fixing base 6 of this embodiment is cylindrical as a whole, and the top of the fixing base 6 is detachably connected to the stator of the second motor 51. A dynamic seal is used between the rotor of the second motor 51 and the fixing base 6, such as an oil seal. The bottom of the fixing base 6 is provided with an inwardly recessed battery slot 61, and the battery slot 61 is used to plug in the battery 8 to power the vehicle-mounted infrared pan-tilt device. The battery 8 is detachably connected to the fixing base 6. When the battery 8 is needed for power supply, the battery 8 can be inserted into the battery slot 61, and the electrodes of the battery 8 are connected to the positive and negative pins (or sockets, contacts, etc.) of the second control circuit board above the battery slot 61, so that the battery 8 can power the vehicle-mounted infrared pan-tilt device. The battery 8 can be a special-purpose battery or a universal battery of existing specifications and models. At the same time, the battery 8 can be an ordinary dry cell battery or a rechargeable battery. The presence of battery 8 enables the vehicle-mounted infrared pan-tilt device to adapt to a wider range of outdoor applications, regardless of whether there is an outdoor power supply. When a power supply is available, the vehicle-mounted infrared pan-tilt device can be directly plugged into the power supply for use. In the absence of a power supply, the device can be powered by battery 8. A second controller is provided on the second control circuit board, which is electrically connected to the second motor 51 and is used to control the rotation speed and angle of the second motor 51. The horizontal rotation assembly 5 also includes a conductive slip ring, through which the circuit of the first control circuit board is connected to the second control circuit board, ensuring that the horizontal rotation assembly 5 rotates continuously 360 degrees without signal loss.

[0039] like Figure 4 As shown, a wireless communication module and a connector 15 are further provided below the horizontal rotation component 5, and the wireless communication module and the connector 15 are electrically connected to the second control circuit board, respectively. The connector 15 can be, for example, an aviation plug harness interface for connecting to external electronic devices (such as mobile phones, display devices, etc.). The wireless communication module can be, for example, a Bluetooth module or a WiFi module with an external antenna 12. The connector 15 and the external antenna 12 are respectively provided on the side walls of the fixing seat 6. The external antenna 12 can enhance the wireless transmission signal to facilitate real-time control and observation of the imaging video. It can get rid of the constraints of the wiring harness of the traditional pan-tilt device, freely choose the usage scenario, and open the APP on the electronic device at any time to observe the imaging video and control the rotation of the vehicle-mounted infrared pan-tilt device.

[0040] like Figure 2 and Figure 4 As shown, a housing 4 is provided around the periphery of the fixing base 6 and on the outside of the two side frames 31. At each connection port 15 of the vehicle-mounted infrared pan / tilt device, except for the two locations mentioned above that use dynamic seals, all other locations are sealed with sealing rings 11 to ensure the device's waterproof performance.

[0041] like Figure 1 and Figure 2As shown, to facilitate the secure installation of the vehicle-mounted infrared pan-tilt device, a base mounting bracket 7 is also provided. The fixing base 6 is detachably connected to the top of the base mounting bracket 7. The base mounting bracket 7 is provided with a portable handle. The bottom of the base mounting bracket 7 is provided with a suction fixing structure 72, which is used to secure the vehicle-mounted infrared pan-tilt device in a predetermined position. In this embodiment, the base mounting bracket 7 includes a connecting plate 71. The top of the connecting plate 71 is connected to the fixing base 6. A notch is provided at the connecting plate 71 corresponding to the battery slot 61. This notch is provided to allow for the battery 8 to be properly installed in the battery slot 61. The bottom of the connecting plate 71 is connected to a suction fixing structure 72. In this embodiment, the suction fixing structure 72 is a vacuum suction cup, which can be used to secure the vehicle-mounted infrared pan-tilt device in a vehicle or indoor location. The base mounting bracket 7 and the fixing base 6 are detachably connected, and the vacuum suction cup is also detachably connected to the connecting plate 71. The vacuum suction cup facilitates the securement and relocation of the vehicle-mounted infrared pan-tilt device. The portable handle facilitates the movement of the vehicle-mounted infrared pan-tilt device. Of course, the fixing method of the vehicle-mounted infrared pan-tilt device and the vehicle body is not limited to the adsorption method. Other detachable installation methods are also applicable. For example, it can be installed by gluing or threaded connection. At this time, the bottom structure of the base mounting bracket 7 can be adaptively adjusted. The above-mentioned adsorption fixing structure 72 is the preferred installation method.

[0042] The vehicle-mounted infrared pan-tilt device of the embodiment of the present application has a compact and lightweight structure. The outer diameter of the cylinder at the fixed seat is about 80 mm, the overall height is about 145 mm, and the weight is about 890 g. It can be easily carried with one hand. The vehicle-mounted infrared pan-tilt device of this embodiment integrates functions such as infrared imaging, laser indication, and laser ranging in a very small volume, which can meet the user's needs for tracking, ranging, and indicating multiple functions of the target object. It is provided with an external detachable battery to facilitate powering the device when there is no external power supply. It can be connected to electronic devices through a wireless communication module and a connection port, thereby realizing video observation of the control of the vehicle-mounted infrared pan-tilt device. It can expand more outdoor application scenarios and will not be constrained or affected by whether the outdoor environment is equipped with a power supply and cable connection, which greatly improves the convenience of user use.
