A camera protection device and protection method for an engineering machinery vehicle

Abstract

This invention relates to the field of engineering vehicle monitoring technology, specifically to a protective device and method for a camera on an engineering machinery vehicle. It includes a protective support frame with horizontal connecting rings symmetrically arranged on its left and right sides. It also includes a spherical protective shell positioned above the protective support frame, with its left and right sides connected to the support frame via the horizontal connecting rings. This invention provides comprehensive protection for the internally installed camera through the spherical protective shell and the arc-shaped transparent protective plate. Simultaneously, an integrated ultrasonic sensor monitors the environment in front of the spherical protective shell in real time. Once a high-speed object is detected flying towards the spherical protective shell, the arc-shaped protective plate is immediately released, causing it to quickly flip to the front of the spherical protective shell under the drive of a power-storing spring, forming an immediate protective barrier. This effectively blocks direct impact from high-speed objects to the camera, significantly improving the camera's protective capability and operational safety.

Description

Technical Field

[0001] The present invention relates to the technical field of engineering vehicle monitoring, and in particular to a camera protection device and a protection method for an engineering vehicle. Background Art

[0002] In modern industrial construction and maintenance, construction machinery vehicles such as excavators, loaders, cranes, etc. are equipped with camera monitoring systems to enhance the operator's field of view and improve work efficiency and safety. The cameras on construction machinery vehicles are usually in harsh working environments, including dust, mud, rain, vibration, and extreme temperatures. These cameras face severe tests in harsh working environments, which can easily lead to damage to the camera lens and the internal structure of the camera, seriously affecting its normal operation and service life.

[0003] The patent with application number CN202021858642.2 discloses an engineering vehicle monitoring device, which relates to the field of vehicle-mounted cameras, including a support assembly arranged on the front grille of the engineering vehicle, the support assembly including an inner positioning seat, an outer positioning seat and a lens holder, a lens holder is sandwiched between the inner positioning part and the outer positioning part, a protective shell is provided on the outer positioning part, a mounting cavity is provided in the protective shell, one end of the lens holder is arranged in the mounting cavity, the lens holder is hinged to a camera shell by a hinge screw, a camera is provided in the camera shell, a glass lens is fixed on the camera shell, a lens window is opened at one end of the protective shell away from the support assembly, and one end of the camera shell away from the support assembly is sleeved in the lens window, and by designing a protective shell on the outer positioning part, the camera shell is not exposed to the outside, so as to prevent flying stones from damaging the camera shell.

[0004] However, it is protected by a transparent glass lens.

The adjustment motor 504 drives the camera mounting seat 5 to rotate along the adjustment connecting ring 501 through the adjustment gear 503 and the adjustment gear ring 502, thereby driving the camera installed thereon to rotate synchronously, thereby adjusting the camera. The protective motor 405 drives the spherical protective shell 4 and the arc-shaped transparent protective plate 401 to rotate along the rotating connecting ring 402 as a whole through the protective gear 404 and the protective gear ring 403. When the spherical protective shell 4 and the arc-shaped transparent protective plate 401 rotate backward to the bottom, a plurality of cleaning nozzles 804 spray water to the surface of the spherical protective shell 4 and the arc-shaped transparent protective plate 401 to clean them, and then rotate to the cleaning scraper 807, and the cleaning scraper 807 is used to scrape the surface of the arc-shaped transparent protective plate 401 to remove dirt and water stains. At the same time, the device uses the ultrasonic sensor 601 and the laser The light transmitter 602 and the laser receiver 603 can jointly monitor the environment in front of the spherical protective shell 4 in real time. Once an object is detected flying towards the spherical protective shell 4 at high speed, the protection mechanism can be triggered. When the arc-shaped protective plate 7 rotates to the back side of the spherical protective shell 4 through the protection connecting ring 701, it drives the power storage coil spring 702 to contract and store energy, and the arc-shaped protective plate 7 is locked by embedding the elastic locking pin 205 in the middle of the locking slot 703. When the protection mechanism is triggered, the unlocking electromagnet 206 responds quickly, attracting the elastic locking pin 205 to disengage from the locking slot 703, releasing the arc-shaped protective plate 7, and making it close to the power storage coil spring 702. 02, it quickly flips to the front side of the spherical protective shell 4, forming an instant protective barrier, which effectively blocks the direct impact of high-speed objects on the camera and the arc-shaped transparent protective plate 401. After completing the covering protection, the reset motor 706 drives the protective connecting ring 701 to rotate in the opposite direction through the reset gear 705 and the reset gear ring 704, thereby driving the arc-shaped protective plate 7 to rotate along the protective connecting ring 701 to the rear side of the spherical protective shell 4, and at the same time drives the force storage coil spring 702 to contract and store energy until the elastic locking pin 205 is embedded in the middle of the locking slot 703 to lock the arc-shaped protective plate 7, thereby completing the automatic reset of the arc-shaped protective plate 7.

[0059] S4: The stored force coil spring 702 releases the previously stored energy, driving the arc-shaped protective plate 7 to quickly flip forward along the protective connecting ring 701 to the front side of the spherical protective shell 4, covering the front side of the arc-shaped transparent protective plate 401 to form an instant protective barrier;

[0060] S5: When the protection is completed, the arc-shaped protective plate 7 is rotated to the rear side of the spherical protective shell 4 through the protective connecting ring 701, and at the same time, the force storage coil spring 702 is driven to contract and store energy, and then the unlocking electromagnet 206 is powered off, and the elastic locking pin 205 is automatically reset and re-embedded in the locking slot 703 under the action of the spring force, locking the arc-shaped protective plate 7 in the rear position and restoring the initial working state, waiting for the next triggering of the protection response.
