A wide-range wiper structure controlled by a single motor

Abstract

The invention specifically discloses a large-scale wiper structure controlled by a single motor, including a motor, a mounting seat and a connecting rod. The mounting seat is provided with a driving gear shaft and a driven gear shaft. The other end of the rod is connected to the driven gear shaft, the motor is connected to the driving gear shaft, and the first pinion shaft and the second pinion shaft are also arranged on the mounting base, and the driving gear shaft and the driven gear shaft are arranged on the first pinion shaft and the second pinion shaft. Between the gear shafts, the driving gear shaft and the first gear shaft are engaged for transmission, and the driven gear shaft is engaged for transmission with the second gear shaft. Both the first gear shaft and the second gear shaft are connected with a wiper assembly. The wiper structure is used It is used to scrape and clean the optical lens and fill light lens on the radar to ensure that the lens can be rotated and shot clearly in various weathers and environments; the structure is compact, the installation is convenient, the space is small, the overall structure is independent, and it can be used independently The installation will not affect the working performance of other modules on the radar, and the scratching range is larger.

Description

technical field [0001] The invention relates to the technical field of wipers, in particular to a large-scale wiper structure controlled by a single motor. Background technique [0002] At present, all FOD radars require a compact and short overall structure. The purpose is to minimize the volume of the radars arranged on both sides of the runway and avoid the pressure on the pilots due to the excessive volume. Since there are many functional modules inside the radar, it needs to occupy most of the space, so the available space for the wiper drive device is very small. Therefore, the existing FOD radar has a small wiper coverage area, generally only in the positive direction. Use wipers on some small areas of the protective glass of the optical lens. The cleaning range is very limited. When the optical lens is rotated with an angle, there may be some protective glass in front of the lens that will not be cleaned. This situation is very easy It affects the monitoring effect ...

Problems solved by technology

Since there are many functional modules inside the radar itself, most of the space needs to be occupied, so the available space for the wiper driving device is very small. Therefore, the wiper coverage of the existing FOD radar is small, and generally only in the normal Use the wiper on some small areas of the protective glass of the optical lens, and the cleaning range is very limited. When the optical lens rotates at an angle, some protective glass in front of the lens may not be cleaned, which is easy In addition, if the radar design also includes other protective glass with cleaning requirements such as lens fill light, the existing wiper cleaning range cannot meet the design requirements.
