As shown, the vehicular surveillance apparatus 100 according to the first embodiment of the present invention may include an image acquisition unit 110, a bracket 120, and a driver 130.

The image acquisition unit 110 may be understood as a device that is exposed to the outside of the vehicle, such as a camera, to acquire an image of the outside of the vehicle, for example, an image of the front or rear of the vehicle, and the image acquisition unit 110 is installed. The direction may vary depending on the direction in which the image is to be acquired. In the first embodiment of the present invention, the image acquisition unit 110 will be described in the case of being installed in the rear of the vehicle, for example, the trunk lid for rearward monitoring when the vehicle is reversed, but is not limited thereto.

The bracket 120 may include an image acquisition unit 110 and may rotate in a predetermined direction so that the image acquisition unit 110 may be exposed to the outside of the vehicle. The image acquisition unit 110 may be installed and fixed to the bracket 120 by coupling screws 111 and 112. One surface of the bracket 120 is visible from the outside of the vehicle, and when the bracket 120 rotates, the image acquisition unit 110 installed on the bracket 120 may be exposed to the outside while the one surface viewed from the outside of the vehicle is rotated. .

One surface exposed to the outside of the vehicle from the bracket 120 may be formed in a similar shape to the outside of the vehicle, for example, similar in color or material to prevent the driver from feeling a heterogeneity due to one surface of the bracket 120 from the outside of the vehicle. have. In addition, an attachment having a predetermined shape may be attached to one surface of the bracket 120 to the outside of the vehicle. The attachment may be an emblem of a vehicle, a sticker attached to a driver's taste, or the like. The attachment may be attached at the time of shipment from the vehicle, or may be attached after the shipment from the vehicle. The attachment may be attached to one surface of the bracket 120, or may be integrally formed when the bracket 120 is manufactured.

The driving unit 130 may include an actuator 131 and a plurality of gears 132, 133, and 134. In the first embodiment of the present invention, the plurality of gears 132, 133, and 134 may be formed of a first gear, respectively. 132, the second gear 133 and the third gear 134 will be referred to as.

The actuator 131 generates a rotational force about the rotation shaft 131a when the driving power is applied, and the first gear (rotating in the same direction as the rotation direction of the rotation shaft 131a) on the rotation shaft 131a of the actuator 131. 132, for example, a worm gear can be installed.

In addition, the first gear 132 may be provided with a manual adjustment unit 132a capable of inserting a mechanism such as a driver at an end opposite to the outside of the vehicle, and may be omitted in some cases. The manual adjustment unit 132a may rotate the bracket 120 even when the image acquisition unit 110 is not separated from the vehicle by using a mechanism such as a driver when a failure or malfunction occurs. In addition, a hole (not shown) communicating with the manual adjustment unit 132a may be formed at a portion of the trunk lid or the like to allow access to the manual adjustment unit 132a through a mechanism such as a driver.

The second gear 133 rotates about the rotation shaft 133a and may have a rotation direction different from that of the first gear 132. In the first embodiment of the present invention, a case in which the first gear 132 and the second gear 133 change the rotation direction in the vertical direction will be described with an example. As such, the rotation directions of the first gear 132 and the second gear 133 are different from each other in order to prevent the bracket 120 from rotating in the case of an interaction error.

The third gear 134 is connected to the bracket 120 and rotated by the second gear 133 so that the bracket 120 can rotate in a predetermined direction. In this case, the third gear 134 may be formed in a fan shape having a tooth of a length corresponding to the angle at which the bracket 120 rotates. In the first embodiment of the present invention, the third gear 134 has a fan shape, but is merely an example to help understanding the present invention, but is not limited thereto.

Accordingly, since the bracket 120 and the third gear 134 are connected by the hinge shaft 140, the bracket 120 and the third gear 134 may be prevented from being separated from the bracket 120.

In addition, the coupling hole 122 which allows the bracket 120 and the third gear 134 to be coupled to each other by the coupling protrusion 122a on one side of the insertion hole 121 and the third gear 134 of the bracket 120. , 134b) may be formed respectively.

As such, the coupling hole 122 of the bracket 120 and the coupling hole 134b of the third gear 134 through the coupling protrusion 122a may be coupled to the bracket 120 only by the hinge shaft 140. When the third gear 134 is connected, the rotational force is hardly transmitted to the bracket 120 because the position of the third gear 134 is difficult to be fixed. Therefore, in the first embodiment of the present invention, since the bracket 120 and the third gear 134 are connected by the hinge shaft 140 and the engaging protrusion 122a, the rotational force of the third gear 134 is the bracket 120. To facilitate delivery.

Meanwhile, in the first embodiment of the present invention, the bracket 120 and the third gear 134 are described with an example in which the hinge shaft 140 and the coupling protrusion 122a are connected to each other. As an example to help understanding, the present invention is not limited thereto, and when the hinge shaft 140 and the third gear 134 are integrally formed, the coupling by the coupling protrusion 122a may be omitted.

Meanwhile, the hinge shaft 140 has a bracket to prevent the position of the third gear 134 connected to the insertion hole 121 of the bracket 120 by the hinge shaft 140 from being changed along the hinge shaft 140. The fixing protrusion 141 may be formed at a distance corresponding to the thickness of the third gear 134 from the insertion hole 121 of the 120. In the first embodiment of the present invention, the fixing protrusion 141 has been described as an example formed along the entire circumference of the hinge shaft 140, but this is merely an example for helping understanding of the present invention, and the present invention is not limited thereto. It may be formed only in the circumferential portion of the hinge shaft 140 without.

In addition, in the vehicular monitoring apparatus 100 according to the first embodiment of the present invention, a sensing unit 150 for detecting the rotation of the bracket 120 may be installed at one side of the bracket 120. 150 includes a first contact portion 151 and a second contact portion 152, and since the first contact portion 151 is formed to be bent to the bracket 120 side, the first contact portion 151 according to the position of the bracket 120. ) And the contact of the second contact portion 152 may be determined to detect the position of the bracket 120. The installation position or the number of the sensing unit 150 may be changed in various ways depending on the use and need.

2 is a perspective view illustrating a driving unit of a vehicle sensing apparatus according to a first embodiment of the present invention.

As shown, the drive unit 130 according to the first embodiment of the present invention is a second gear that is rotated by the first gear 132 and the first gear 132 connected to the rotary shaft 13a of the actuator 131 It can be seen that 133 has the rotation axis in the vertical direction to each other. In addition, it can be seen that the rotation axis of the second gear 133 and the third gear 134 are parallel. In addition, it can be seen that the manual adjustment unit 132a is formed at the end opposite to the vehicle outer side of the first gear 132.

As described above, since the second gear 133 changes the rotational force by the actuator 131 in the direction perpendicular to the rotation axis 131a of the actuator 131 and transmits the rotational force to the third gear 134, the first and second gears. It is possible to prevent the bracket 120 from rotating due to a malfunction of one of the gears 132 and 133. For example, when the actuator 131 malfunctions, the bracket 120 is prevented from rotating by the second gear 133, and when the second gear 133 malfunctions, the bracket 120 is prevented from rotating. It is possible to prevent the bracket 120 from rotating.

Therefore, the implementation of the so-called self-lock function, which prevents malfunction by the first gear 132, the second gear 133, and the third gear 134 of FIG. 2, adds a separate component. It can be implemented without
