In general, in the assembling process of the camera device, the rotation angle of the camera is set and the camera is fixed at the set rotation angle. Recently, a method of fixing the rotation angle of the camera by combining the cover portion and the proximal portion covering the camera unit with each other has been studied.

However, as the camera rotates along the cover in a process of assembling the cover by rotating the cover relative to the proximal end, a set angle of the camera is distorted. This error change of the camera angle is a problem that is deepened as the product size of the camera device increases.

In addition, considering that the cover portion of the base portion is mostly assembled by hand, considering the structure of the narrow camera device is difficult to secure sufficient working space for the rotation operation is less workability of the assembly work Problems also arise.

An object of the present invention is to provide a camera device that not only improves the ease of assembly work by improving the assembly structure involved in the angle fixing of the camera, but also stably maintains the set angle of the camera during assembly.

According to the present invention, the assembling work for fixing the angle of the camera is performed by a relatively simple operation, such as screw fastening, one-touch latch fastening or hook fastening, thereby improving the assembly of the camera.

In addition, since the camera is assembled in a state in which the set rotation angle is not twisted in error and maintains the set rotation angle, it is possible to produce a camera device in which original design specifications are faithfully reflected regardless of the product size.

Hereinafter, a camera apparatus according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. An exploded perspective view of the camera device 100 is shown in FIG. 1, and a structure of the camera device 100 viewed from above is shown in FIG. 2. In FIG. 2, for convenience of understanding, illustration of some components of FIG. 1 is omitted.

The illustrated camera device 100 includes a spherical camera assembly 120, a base 110 on which the camera assembly 120 is rotatable at an arbitrary angle, and an internal contact with the camera assembly 120. A guide cover 150 assembled on the base 110 to cover 120, an annular fastener 170 assembled to an outer circumference of the guide cover 150, and the fastener 170 and the guide cover 150. It includes a cylindrical pressing piece 160 interposed therebetween.

The camera assembly 120 is seated on the base 110. More specifically, the camera assembly 120 has an annular rim shape and is placed on the support 118 of the base protruding upward. The camera assembly 120 is in ball joint contact with the base 110 to be adjustable in any rotational direction.

The guide cover 150 is assembled on the base 110 to cover the camera assembly 120. More specifically, the guide cover 150 is formed of a substantially cylindrical hollow member, and has a hollow portion 150` of the lower light upper side. The guide cover 150 is assembled on the base 110 to cover and cover the camera assembly 120. The upper portion of the guide cover 150 is inscribed on the surface of the camera assembly 120. The assembled camera assembly 120 is in sliding contact with the guide cover 150, while making a ball joint contact with the base 110 can be adjusted in any rotational direction. The guide cover 150 has an opening OP for exposing the optical lens 121 of the camera assembly 120.

An annular fixture 170 is fitted to the outer circumference of the guide cover 150. The fastener 170 is composed of an annular member having one side open, the fastener 170 fitted to surround the guide cover 150 is a base 110 by a hinge shaft 181 passing through the open end 171. Hinged). As can be seen in Figure 2, the base 110 is provided with a coupling piece 111 to which the hinge shaft 181 is coupled. The hinge shaft 181 hinges the fixture 170 with respect to the base 110 while coaxially penetrating the coupling end 111 of the base 110 together with the open end 171 of the fixture 170.

Referring to FIG. 1, the fastener 170 is rotatably coupled with respect to the base 110 about the hinge axis 181, and has a screw member 185 at a part of the fastener 170 opposite to the hinge axis 181. ) Is fastened. By the fastening force of the screw member 185, the fixture 170 is pressed downward while rotating toward the base 110 around the hinge axis 181. At this time, the guide cover 150 pressed downward with the fixture 170 is fixed by pressing the camera assembly 120 accommodated therein. At this time, the camera assembly 120 is fixed at a set rotation angle to maintain a stable rotation state. On the other hand, as long as it can provide a fastening force for the fastener 170, various kinds of mechanical fastening elements can be considered in place of the screw member 185, of course. For example, a one-touch latch member or hook member may be used in place of the screw member 185.

The pressing piece 160 may be interposed between the fixture 170 and the guide cover 150. The pressing pieces 160 may have a circumferential shape surrounding the guide cover 150, and may be disposed in pairs from side to side to press the guide cover 150 in a symmetrical position. For example, the pressing piece 160 and the fixture 170 may be in pressure contact with each other through the rounded protrusion 175. The pressing piece 160 may be formed with an inlet portion 165 recessedly inserted into a shape that matches the protrusion 175. The fastener 170 which pivots downwardly about the hinge axis 181 by screwing down pushes the guide cover 150 through the pressing piece 160. The fixture 170 that pivots about the hinge axis 181 basically performs a rotational motion. If the pressing piece 160 is not interposed and the guide cover 150 is directly pressurized by the fixture 170, the possibility that the guide cover 150 may be assembled in an oblique inclination position along the rotation of the fixture 170 may result. This is big. The pressing piece 160 converts the rotation operation of the fixture 170 into the translational motion in the vertical direction through the sliding contact. The guide cover 150 may be assembled in a horizontal position while being pressed down by the downward movement of the pressing piece 160, and may stably fix the camera assembly 120 at a uniform pressure.

Pressing contact between the fixture 170 and the pressing piece 160 constitutes an interlocking mechanism that converts the rotational movement of the fixture 170 into a translational motion in the vertical direction. That is, the rotational movement of the fixture 170 about the hinge axis 181 is the vertical translation of the pressing piece 160 through the pressing contact surface (corresponding to the protrusion 175 of the fixture and the inlet 165 of the pressing piece). Is converted to an action. Then, while the guide cover 150 is pushed downward by the pressing piece 160, the rotation angle of the camera assembly 120 accommodated in the guide cover 150 is fixed. As can be seen in Figure 2, the base 110 may be provided with an assembly guide 116 to define the assembly position of the pressing piece 160. Meanwhile, reference numeral 115 not described in FIG. 2 denotes a fastening hole on the base 110 to which the screw member 185 penetrating the fixture 170 is fastened.

3 shows a side structure of the camera device. The illustration of the base is omitted for ease of understanding. Referring to the drawings, the fastener 170 is pivoted downwardly about the hinge axis 181 by the screw member 185 that is fastened to the base 110 downward through the fastener 170, The pivoting motion of the fixture 170 is converted to the downward motion of the pressure piece 160 which is in pressure contact through the protrusion 175. Here, the operating point (P1) is applied to the fastening force of the screw member 185 is located at a distance (L1) from the hinge axis 181, while the operating point (P2) for transmitting the pressing force to the pressing piece 160 is a hinge Since it is located at a relatively short distance (L2) from the shaft 181, the fixture 170 can transmit the pressing force doubled compared to the fastening force of the screw member 185 by the lever principle to the pressing piece 160, and as a result The camera assembly 120 may be firmly fixed through the guide cover 150. As the screw member 185 is fastened to the base 110, the rotation angle of the camera is fixed, and a camera device 100 as shown in FIG. 4 is provided. Here, referring to FIG. 1, an optically transparent housing case 190 may be assembled on the base 110 to cover the entirety of the camera apparatus 100. The housing case 190 forms an appearance of the camera device 100, and may function to maintain a beautiful appearance and protect internal components.
