Abstract
Description
Technical Field
[0001] This utility model relates to a bus rearview mirror, and in particular a bus rearview mirror with a cleanable lane-change camera. Background Technology
[0002] When a bus is in motion, it is necessary to observe the road conditions on both sides and behind the vehicle through the rearview mirror. Nowadays, more and more rearview mirrors are equipped with cameras to help drivers better observe the road conditions on both sides and behind the vehicle. However, when it rains or snows or the surrounding environment is poor, the camera lens will get dirty with impurities, affecting the normal use of the camera. If it is not cleaned in time, it will pose a significant safety hazard. Summary of the Invention
[0003] The purpose of this invention is to provide a bus rearview mirror with a cleanable lane-change camera that can clean the camera lens in a timely manner.
[0004] The technical solution to achieve the purpose of this utility model is as follows:
[0005] A bus rearview mirror with a cleanable lane-change camera includes a bracket for connecting to the vehicle body and a rearview mirror fixed on the bracket. The rearview mirror includes a mirror housing and a lens fixed inside the mirror housing. The lens includes a flat upper portion and a curved lower portion. The curved portion has a notch, at which a lane-change camera for capturing road conditions behind the vehicle is disposed. The lane-change camera has a lens and is fixedly connected to the mirror housing. A stepper motor is fixedly disposed inside the mirror housing. The stepper motor has a rotating shaft, and a rotating plate is fixed on the rotating shaft. The rotating plate is three-quarters circular in shape. In the direction from the mirror housing to the lens, the rotating plate is located between the lane-change camera and the lens. A cleaning cloth is disposed on the side of the rotating plate facing away from the lens. When the rotating plate rotates, the cleaning cloth contacts the lens of the lane-change camera.
[0006] With the above structure, when the camera lens becomes dirty and affects normal shooting, the stepper motor is turned on. The stepper motor rotates an integer number of revolutions, which can quickly clean the camera lens. At the same time, when the motor stops, the rotating plate will not block the camera, ensuring the normal use of the camera. This utility model can quickly clean the camera on the rearview mirror, ensure the normal use of the camera, and improve the safety of bus driving.
[0007] Preferably, in order to ensure that the cleaning cloth exerts sufficient pressure on the camera lens to ensure the cleaning effect, the rotating plate is provided with multiple springs. One end of the spring is connected to the rotating plate, and the other end is fixed to a mounting plate. The side of the mounting plate facing away from the lens is fixedly connected to the cleaning cloth.
[0008] Preferably, in order to facilitate the rotation of the cleaning cloth onto the lens, the lane-changing camera is provided with guide slopes around the lens.
[0009] Preferably, to prevent the motor from getting damp, the rearview mirror housing is fixed with a hollow cylindrical sleeve, and the motor is installed inside the sleeve. Attached Figure Description
[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0011] Figure 1 This is a schematic diagram of the structure of this utility model.
[0012] Figure 2 This is a schematic diagram of the assembly of the rotating plate and the cleaning cloth of this utility model.
[0013] Figure 3 This is a schematic diagram of the rotating plate structure of this utility model. Detailed Implementation
[0014] like Figures 1 to 3 As shown, the present invention relates to a bus rearview mirror with a cleanable lane-change camera, comprising a bracket 1 for connection to the vehicle body and a rearview mirror fixed on the bracket. The rearview mirror includes a mirror housing 2 and a lens fixed within the mirror housing. The lens includes a flat upper portion 3 and a curved lower portion 4. The curved portion has a notch 5, at which a lane-change camera 6 for capturing road conditions behind the vehicle is disposed. The lane-change camera has a lens 7. The lane-change camera is fixedly connected to the rearview mirror housing. A stepper motor 8 is fixedly disposed within the rearview mirror housing, and the stepper motor has a rotation function. A rotating plate 10 is fixed on a rotating shaft 9. The rotating plate has an opening, and its projection along the axial direction of the rotating shaft is a three-quarter circle. In the direction from the rearview mirror housing to the lens, the rotating plate is located between the lane-changing camera and the lens. Under normal use, the opening of the rearview mirror corresponds to the lens of the camera, meaning the rotating plate does not obstruct the camera's view. Multiple springs 12 are installed on the rotating plate, with one end connected to the rotating plate and the other end fixed to a mounting plate 13. The side of the mounting plate facing away from the lens is fixedly connected to a cleaning cloth 11. When the rotating plate rotates, the cleaning cloth contacts the lens of the lane-changing camera. Guide slopes 14 are provided around the lens of the lane-changing camera. A hollow cylindrical sleeve 15 is fixed to the rearview mirror housing, and the motor is housed within the sleeve.
[0015] With the above structure, when the camera lens becomes dirty and affects normal shooting, the stepper motor is turned on. The stepper motor rotates an integer number of revolutions, which can quickly clean the camera lens. At the same time, when the motor stops, the rotating plate will not block the camera, ensuring the normal use of the camera. This utility model can quickly clean the camera on the rearview mirror, ensure the normal use of the camera, and improve the safety of bus driving.
[0016] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
