Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle-mounted light and ventilation shafts, specifically to a vehicle-mounted light and ventilation shaft. Background Technology
[0002] The vehicle-mounted optical and ventilation shaft is typically located above the derotation shaft and is part of the pitch shaft. One end is connected to the top optical head, and the other end rotates with the pitch frame, but its optical and ventilation paths need to pass through the lower azimuth shaft to connect to fixed equipment inside the vehicle body.
[0003] The vehicle-mounted optical and ventilation shaft serves both optical and ventilation functions, acting as a physical channel for optical communication. The shaft incorporates a sophisticated optical path design. Laser signals are emitted from a device fixed at the bottom, transmitted through a reflector or fiber optic rotary connector within the shaft, and then to a rotating communication head at the top, enabling uninterrupted 360° continuous rotation communication. During ventilation, it primarily provides a cooling gas source (such as high-pressure gas or cryogenic nitrogen) for the internal optical equipment (e.g., infrared detectors, lasers) or keeps the interior dry (by ventilating with dry air or nitrogen), preventing fogging and frost formation on the lenses.
[0004] This utility model proposes a vehicle-mounted light and ventilation shaft. Utility Model Content
[0005] In order to overcome the defects in the prior art, this utility model provides a vehicle-mounted light and air shaft. After installing a seal, optical fiber and corresponding optical path components, it can effectively achieve the effects of light and air transmission. The overall structure is simple, easy to process, and has a high overall processing qualification rate, which reduces the cost caused by defective products.
[0006] Technical solution
[0007] A vehicle-mounted optical and ventilation shaft includes a shaft body with a hollow pipe inside. One end of the hollow pipe is provided with an internal thread, and the other end of the hollow pipe is connected to a mounting cavity for installing a seal. An optical fiber through hole penetrating the shaft body is provided on the other side of the mounting cavity, and a side channel penetrating the shaft body and communicating with the mounting cavity is also provided on one side of the optical fiber through hole.
[0008] Furthermore, an outer edge portion is provided on the outside of one end of the shaft.
[0009] Furthermore, the outer edge of the ring array has several through holes.
[0010] Furthermore, the side of the through hole away from the hollow pipe is chamfered.
[0011] Furthermore, the internal thread and the outer edge are located on the same side of the shaft.
[0012] Furthermore, the sealing element is installed inside the mounting cavity, and an optical fiber penetrating the optical fiber through hole is connected to the sealing element.
