Description

Rear camera device for vehicle The present invention relates to a rear camera mounted on the rear of a vehicle, and more specifically, to a vehicle rear camera device in which a housing is installed that is embedded in the rear of the vehicle and one side of which is opened and closed by a door, and a rear camera is embedded in the housing. Generally, a rear camera device is mounted at the rear of the vehicle to display the situation behind the vehicle to the driver inside the cabin via a monitor during reverse driving or reverse parking. A vehicle equipped with this rear camera device provides convenience during reverse driving or reverse parking and can significantly reduce the risk of rear-end collisions. For example, such a rear camera device may be fixed so as to protrude or be exposed at the rear of the vehicle, thereby allowing the camera lens to always be installed with the lens exposed to the outside. However, this has the problem that the camera lens may be easily damaged by external impact, or it may be difficult to obtain a clear image due to dirt adhering to it or numerous scratches. The following drawings attached to this specification illustrate preferred embodiments of the present invention and serve to further enhance understanding of the technical concept of the present invention together with the detailed description thereof; therefore, the present invention should not be interpreted as being limited only to the matters described in such drawings. FIG. 1 is a schematic diagram illustrating a rear camera device for a vehicle according to a preferred embodiment of the present invention. Figure 2 is a cross-sectional view along line AA of Figure 1, showing the state in which a camera is accommodated. Figure 3 is a drawing showing the state in which the camera is withdrawn from Figure 2. Figure 4 is an enlarged view of the camera module shown in Figure 2. Hereinafter, preferred embodiments are described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. Furthermore, among the configurations mentioned in the various embodiments, mutually similar configurations and related configurations in each embodiment may be substituted, replaced, or added. However, in describing the operating principles of the preferred embodiments of the present invention in detail, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description is omitted. A rear camera device for a vehicle according to a preferred embodiment of the present invention may comprise a housing (100), a camera module (200), an opening/closing module (300), and a cleaning module (400), as shown in FIGS. 1 and 2. First, the housing (100) may be manufactured in a roughly rectangular shape with one side open and an internal space (110). Additionally, a camera module (200), an opening/closing module (300), and a cleaning module (400) may be housed in the internal space (110). Next, the camera module (200) may be manufactured to photograph the rear of the vehicle. When not photographing, the camera module (200) is housed in the housing (100) and concealed, and when photographing, the door (310) may be opened while rotating on an axis to photograph the rear. As shown in FIGS. 2 and 3, this camera module (200) may include a body (210), a lens (220), a rotating bar (230), a cam (240), a first linkage gear (250), a second linkage gear (260), a driving gear (270), and a power source (280). Here, the body (210) may be embedded to rotate axially on the bottom or side of the housing (100). For example, the body (210) may be mounted on the housing (100) to rotate along the same axis as the rotational center axis of the first linkage gear (250). When the camera module (200) is not taking a picture, the body (210) may be concealed in the internal space (110) of the housing (100) in a downward axial rotation state as shown in FIG. 2, and when the camera module (200) is taking a picture, it may be in an upward axial rotation state as shown in FIG. 4. Additionally, the rear of the body (210) may include a ring portion (211) machined on both sides of the body (210) in the width direction so that a rotating bar (230) is fitted and engaged. This ring portion (211) is a connecting part for allowing the body (210) to rotate axially together with the rotating bar (230), and can be modified in various general configurations and ways. Additionally, the lens (220) may be positioned on one side of the body (210) and exposed to the outside so as to photograph the rear of the vehicle when the door (310) opens and the body (210) rotates upward. The lens (220) may be positioned at a slight downward angle to photograph the rear of the vehicle and the ground. Additionally, the rotating bar (230) is hooked and coupled to the ring portion (211) of the body (210), and one end portion can b
