Detailed Description

Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.

In the related art, in order to collect vehicle information of road sections before and after the upright post point, two monitoring cameras are required to be fixedly installed on the upright post in different positions. After the monitoring camera is installed, if deviation exists in shooting posture, related personnel are required to ascend again to manually adjust the monitoring camera, the operation is very inconvenient, and the efficiency is low.

Based on this, the embodiment of the present disclosure provides a monitoring apparatus that not only has a large shooting field of view, but also is excellent in operation convenience when adjusting its shooting attitude.

As shown in fig. 5, each pan-tilt mechanism 130 includes a first drive motor 301, a second drive motor 304, a first bracket 302, and a second bracket 303. The first driving motor 301 is disposed in the pan-tilt base 110 and electrically connected to the circuit board 120. The first bracket 302 is disposed above the pan-tilt base 110 and can be driven to horizontally rotate by the first driving motor 301. The second bracket 303 is disposed above the pan-tilt base 110 and is hinged to the first bracket 302 about a horizontal axis. The second driving motor 304 is disposed in the second bracket 303 and electrically connected to the circuit board 120, and is used for driving the second bracket 303 to rotate in a pitching manner around a horizontal axis relative to the first bracket 302. The two cameras 140 are fixedly connected with the second brackets 303 of the two pan-tilt mechanisms 130 in a one-to-one correspondence.

According to the above-described embodiments of the present disclosure, the two pan-tilt mechanisms 130 may receive signals from the circuit board 120 to independently adjust the posture of the camera 140, for example, the pan-tilt mechanism 130 may adjust the left and right photographing views of the camera 140 by adjusting the horizontal rotation angle of the first bracket 302 and may adjust the up and down photographing views of the camera 140 by adjusting the pitch rotation angle of the second bracket 303. The two pan-tilt mechanisms 130 are electrically controlled, so that the monitoring apparatus 100 can not only adjust the displacement to obtain a large shooting field of view, but also is excellent in the convenience of operation in adjusting the shooting posture thereof. For example, the monitoring device 100 may be equipped with a remote controller or a wireless transceiver module, and a person associated with the monitoring device may operate the remote controller or other terminals to conveniently adjust the respective shooting attitudes of the two cameras 140, so as to implement monitoring shooting of the target visual field range (such as a road section in front of and a road section behind the pole). The monitoring device 100 of the embodiment of the disclosure is particularly suitable for parking scenes, and can collect vehicle information of road sections before and after the upright pole.

In some embodiments of the present disclosure, the pan-tilt base 110 is configured to be secured to a pole, such as to the top of the pole. Each camera 140 is a gun-type camera. Gun-type cameras refer to a type of camera that is similar in shape to a gun, the intrinsic configuration and size parameters of which can be selected as desired, and this disclosure is not particularly limited.

In some embodiments of the present disclosure, the pan-tilt base 110 may also be secured to other suitable mounting carriers, such as walls, roofs, and the like. Depending on the monitoring requirements, the camera 140 may be another type of camera other than a gun-type camera, such as a spherical camera, which is not limited by the present disclosure.

In some embodiments of the present disclosure, as shown in fig. 5, the housings of the two cameras 140 are integrally connected with the second brackets 303 of the two pan-tilt mechanisms 130 in a one-to-one correspondence. That is, the housing of the camera 140 is integrally formed with the corresponding second bracket 303. This makes the exterior structure of the monitoring device 100 more compact and aesthetically pleasing.

In other embodiments of the present disclosure, the second bracket of each pan-tilt mechanism is provided with a camera mounting portion, and the housings of the two cameras are detachably connected (e.g., clamped or connected by fasteners) to the camera mounting portions of the second brackets of the two pan-tilt mechanisms in a one-to-one correspondence. That is, the camera and the corresponding holder mechanism are detachable, different types and specifications of cameras and holder mechanisms can be selected for installation according to requirements, and the product application is more flexible.

The pan-tilt base 110 may have a box-shaped appearance structure, such as a rectangular box-shaped structure shown in fig. 1, which is not particularly limited in the present disclosure. Some limiting and mounting structures may be disposed in the pan-tilt base 110, for example, supporting ribs for supporting and fixing the first driving motor 301, clamping grooves for limiting and fixing the circuit board 120, and the like.

Referring to fig. 3 and 4, in some embodiments of the present disclosure, each pan-tilt mechanism 130 further includes: the transmission conversion member 305 and the first bearing 306, wherein the transmission conversion member 305 is fixedly assembled with the output end (such as the output shaft) of the first driving motor 301, the first bracket 302 is fixedly assembled (such as interference assembly) with the transmission conversion member 305, and the first bearing 306 is disposed between two surfaces of the transmission conversion member 305 and the pan-tilt base 110 that generate relative rotation. The first bearing 306 can reduce friction between the transmission conversion member 305 and the pan-tilt base 110, and improve the rotation precision of the transmission conversion member 305.

The embodiment of the present disclosure is not limited to the specific structural form of the first bracket 302 and the second bracket 303.

In some embodiments, as shown in fig. 1 and 5, the second bracket 303 includes a first support portion 307 and a second support portion 308 that are opposite, the second driving motor 304 is provided to the first support portion 307 or the second support portion 308 (provided to the first support portion 307 in fig. 5), and the first bracket 302 includes a base plate portion 309 and a convex portion 310 that protrudes from the base plate portion 309 and is located between the first support portion 307 and the second support portion 308, so that a stable relative rotational relationship is established between the second bracket 303 and the first bracket 302.

As shown in fig. 5, in some embodiments of the present disclosure, the boss portion 310 has a boss 311 extending in a horizontal axis direction and an annular hole 312 surrounding the boss 311, and the boss 311 is fixedly assembled with an output end (e.g., an output shaft) of the second driving motor 304. Each pan-tilt mechanism 130 includes a sleeve 313 pivotally mounted to the annular hole 312 and fixedly assembled with the second bracket 303, and a second bearing 314 provided between the boss 311 and the two surfaces of the inner wall of the sleeve 313 that generate relative rotation.

When the second driving motor 304 drives the second bracket 303 to rotate in a pitching manner relative to the first bracket 302, the output end of the second driving motor 304 does not rotate due to the fixed assembly with the boss 311, and the second driving motor 304 performs pitching rotation of the entire structure except the output end, the sleeve 313, the second bracket 303, and the camera 140. The sleeve 313 may act as an axis alignment for the pitching rotation of the second bracket 303 and may also facilitate the mounting of the second drive motor 304 to the second bracket 303. The second bearing 314 is disposed between the boss 311 and the inner wall of the sleeve 313, so that friction can be reduced, and the pitching rotation accuracy of the second bracket 303 and the camera 140 can be improved.

As shown in fig. 5, in some embodiments, the sleeve 313 includes a sleeve body portion 331 and a flange portion 332, wherein a first seal ring 315 is disposed between an outer wall of the sleeve body portion 331 and an outer ring sidewall of the annular bore 312, the flange portion 332 is fixedly assembled with the second bracket 303 and a second seal ring 316 is disposed therebetween. The first seal 315 and the second seal 316 may be secured within correspondingly disposed seal mounting grooves.

The flange portion 332 and the second bracket 303 may be fixedly assembled by fasteners such as bolts. This embodiment can significantly improve the waterproof sealing effect of the camera 140 by providing the first sealing ring 315 and the second sealing ring 316.

As shown in fig. 3, in some embodiments of the present disclosure, a detachable cover plate 101 is disposed at the bottom of the pan-tilt base 110, and a third sealing ring 102 is disposed on the peripheral side of the detachable cover plate 101, so that the waterproof tightness of the pan-tilt base 110 can be improved. The third seal 102 may be secured within a correspondingly disposed seal mounting groove.

As shown in fig. 1, the waterproof connection terminal 103 is disposed on the side surface of the pan-tilt base 110, so that rainwater can be prevented from entering the pan-tilt base 110, and the waterproof tightness of the pan-tilt base 110 can be further improved.
