Technical Field

[0001] This utility model belongs to the field of airborne optoelectronic turret technology, and in particular relates to a split-type spherical cabin structure for a two-axis, two-frame airborne optoelectronic turret. Background Technology

[0002] As one of the core detection devices of an aircraft, the airborne optoelectronic turret needs to integrate a variety of optoelectronic sensors (such as infrared thermal imagers, laser rangefinders, etc.) and a servo stabilization platform within a limited space and weight. The two-axis, two-frame structure is the most common structural form in airborne optoelectronic turrets.

[0003] Because the spherical structure of airborne electro-optical turrets can effectively reduce flight drag, and to minimize the space occupied by high-torque pitch motors, existing two-axis, two-frame airborne electro-optical turrets mostly adopt a spherical cabin structure to ensure overall aerodynamic shape. However, the spherical cabin structure inevitably creates some installation dead zones, resulting in decreased turret space utilization, increased turret size and weight, and the existence of dead zones poses challenges to internal maintenance and hinders the compact design of the equipment. Utility Model Content

[0004] In view of this, the present invention aims to propose a split spherical cabin structure for a two-axis, two-frame airborne optoelectronic turret, in order to solve the problems of the existing two-axis, two-frame airborne optoelectronic turret spherical cabin structure having installation dead zones, which leads to a decrease in turret space utilization, an increase in turret size and weight, and the existence of dead zones poses challenges to the internal maintenance of the equipment and hinders the compact design of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a split-type spherical cabin structure for a two-axis, two-frame airborne optoelectronic turret, comprising a pitch frame assembly, a front spherical cabin cover, and a rear spherical cabin cover. The pitch frame assembly, the front spherical cabin cover, and the rear spherical cabin cover together constitute the spherical cabin structure. The front spherical cabin cover and the rear spherical cabin cover are respectively located at the front end and rear end of the pitch frame assembly. The pitch frame assembly includes a pitch frame, an upper cover plate, and a lower cover plate. The pitch frame is an integral structure. The pitch frame includes a left vertical plate, a right vertical plate, and a connecting beam. The left and right vertical plates are connected by the connecting beam.

[0006] Furthermore, the left and right vertical plates are respectively located at the bottom of the left and right ends of the upper cover plate and are connected to the upper cover plate by screws. Upper cover plate sealing strips are provided between the bottom of the left and right ends of the upper cover plate and the top of the left and right vertical plates, respectively.

[0007] Furthermore, the left and right vertical plates are respectively located at the top of the left and right ends of the lower cover plate and are connected to the lower cover plate by screws. A lower cover plate sealing strip is provided between the top of the left and right ends of the lower cover plate and the bottom of the left and right vertical plates, respectively.

[0008] Furthermore, the rear end of the pod front cover is connected to the upper cover plate, the left vertical plate, the right vertical plate, and the lower cover plate by screws, and a front cover sealing strip is provided between the rear end of the pod front cover and the pitch frame assembly.

[0009] Furthermore, the front end of the rear cover of the sphere is connected to the upper cover plate, the left vertical plate, the right vertical plate and the lower cover plate by screws, and a rear cover sealing strip is provided between the front end of the rear cover of the sphere and the pitch frame assembly.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0024] See Figure 1-6This embodiment describes a two-axis, two-frame airborne optoelectronic turret split-type spherical cabin structure, including a pitch frame assembly, a front shroud 1, and a rear shroud 4. The pitch frame assembly, front shroud 1, and rear shroud 4 together constitute the spherical cabin structure, effectively reducing wind resistance and thus reducing the space occupied by the pitch motor. The front shroud 1 and rear shroud 4 are respectively located at the front and rear ends of the pitch frame assembly. The pitch frame assembly includes a pitch frame 3, an upper cover plate 5, and a lower cover plate 2. The pitch frame 3 is an integral structure, including a left vertical plate 13, a right vertical plate 14, and a connecting beam 12. The left and right vertical plates are connected by the connecting beam 12. This embodiment... The spherical cabin pitch frame assembly features a split design, which maximizes the use of the internal space of the spherical cabin while ensuring the coaxiality of the two-axis shafts and overall sealing. This enhances the equipment's ability to carry photoelectric loads. Even with a low-torque pitch motor and spherical cabin structure, it fully utilizes the dead space inside the two-axis, two-frame spherical cabin, improving the turret load space utilization rate. The overall structure is simple, and subsequent maintenance can be performed directly by disassembling the upper cover plate 5 or the lower cover plate 2 of the pitch frame 4. This ensures overall airtightness requirements, facilitates future equipment maintenance, and significantly reduces the processing cost of the pitch frame 4. Furthermore, the integrated design of the pitch frame 4 effectively guarantees the coaxiality of the motor and encoder shafts on both sides.

[0025] In this embodiment, the left vertical plate 13 and the right vertical plate 14 are designed with connecting beams to ensure that they are a whole structure. This allows them to be integrally formed when the pitch frame 4 is machined, and meets the coaxiality requirements of the left and right axes.

[0026] In this embodiment, the left vertical plate 13 and the right vertical plate 14 are respectively located at the bottom of the left and right ends of the upper cover plate 5 and are connected to the upper cover plate 5 by screws. The bottom of the left and right ends of the upper cover plate 5 is provided with an upper cover plate sealing strip 7 between the bottom of the left and right ends of the upper cover plate 5 and the top of the left vertical plate 13 and the right vertical plate 14, respectively. The left vertical plate 13 and the right vertical plate 14 are respectively located at the top of the left and right ends of the lower cover plate 2 and are connected to the lower cover plate 2 by screws. The top of the left and right ends of the lower cover plate 2 is provided with a lower cover plate sealing strip 8 between the top of the left and right ends of the lower cover plate 2 and the bottom of the left vertical plate 13 and the right vertical plate 14, respectively. The design of the upper cover plate sealing strip 7 and the lower cover plate sealing strip 8 can further optimize the electromagnetic shielding effect while ensuring the airtightness of the sphere compartment.

[0027] In this embodiment, the rear end of the front cover 1 of the sphere is connected to the upper cover plate 5, the left vertical plate 13, the right vertical plate 14 and the lower cover plate 2 by screws. A front cover sealing strip 6 is provided between the rear end of the front cover 1 and the pitch frame assembly. The front end of the rear cover 4 of the sphere is connected to the upper cover plate 5, the left vertical plate 13, the right vertical plate 14 and the lower cover plate 2 by screws. A rear cover sealing strip 9 is provided between the front end of the rear cover 4 and the pitch frame assembly. The design of the front cover sealing strip 6 and the rear cover sealing strip 9 can further optimize the electromagnetic shielding effect while ensuring the airtightness of the sphere.

[0028] In this embodiment, to ensure effective screw installation, a local wall thickness is added to the inner wall of the screw connection point of each component, thereby improving the equipment's later maintenance capability and reducing operational complexity.

[0029] In this embodiment, the upper cover plate 5 is provided with an air valve sealing cover 11. The air valve inside the air valve sealing cover 11 can be used to ventilate the entire sphere, thereby ensuring that the environment inside the sphere is dry.

[0030] In this embodiment, a memory card sealing cover 10 is provided on the rear cover 4 of the ball cabin, and the ball cabin memory card can be replaced by removing the memory card sealing cover 10.

[0031] In this embodiment, the memory card sealing cover 10 and the air valve sealing cover 11 are connected to the rear cover 4 of the sphere compartment and the upper cover plate 5 respectively by threads.

[0032] The two-axis, two-frame airborne optoelectronic turret split-type spherical cabin structure described in this embodiment has the characteristics of simple overall structure, easy disassembly and assembly, and convenient implementation. At the same time, its design has the characteristics of easy manufacturing and low cost.
