[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] In the related art, the monitoring device provides night lighting through a lighting component. When the monitoring device is installed close to the ground, the lighting component may project light that is too strong in some areas, and the image of the area recorded by the camera component may be locally exposed, affecting the algorithm recognition of the image of the area.

[0037] Based on this, the applicant conducted in-depth research to solve the problem that the light projected by the lighting component is prone to local excessive light intensity, so as to form the technical solution of the present application.

[0038] Please refer to Figure 1 The utility model proposes a monitoring device 100 and an autonomous patrol machine 1000. The monitoring device can be detachably mounted on an external device. Generally speaking, the external device can have a mobile function and generate a predetermined path based on the patrol area set by the user. The monitoring device 100 and the external device are combined to form a complete machine to complete the automatic patrol work. This machine is usually used in scenes such as houses, companies, parks, etc. with courtyards or sidewalks, and can monitor these environments in real time. In addition, the external device can also be a fixed device without a mobile function. Devices with a structure that can be disassembled and assembled with the monitoring device 100 are within the protection scope of the external device of this application.

[0039] Please refer to the attached Figure 4 The monitoring device 100 provided by the utility model includes: a housing 10; a lighting assembly 20, which is installed on the housing 10, and the lighting assembly 20 includes a lamp board 21, the distance between the center of the lamp board 21 and the ground is 200mm~230mm, the lamp board 21 is inclined upward, and the obtuse angle formed by the lamp board 21 and the ground ranges from 100° to 110°.

[0040] The housing 10 surrounds the internal components and forms a receiving cavity, and its main function is to provide structural support and protection for the internal components of the monitoring device 100 .

[0041] When the monitoring device 100 is installed on an external device, the height range of the center of the light board 21 of the lighting component 20 from the ground is between 200mm and 230mm. The installation height of the lighting component 20 is adapted to the height of the external device. Usually, the lighting component 20 in the above height range can illuminate part of the ground and the necessary environment above the ground, so that the lighting range meets the conditions for the monitoring device 100 to identify obstacles. The light board 21 is tilted upward, and can project the strong light in the center of the light board 21 to the environment above the ground. The obtuse angle formed by the light board 21 and the ground is in the range of 100° to 110°, which is matched with the height range of the center of the light board 21 of the lighting component 20 from the ground, further avoiding the overexposure of the camera component 30 caused by the strong light projected on the ground.

[0042] Please refer to Figure 3 In some embodiments, the lighting assembly 20 further includes an outer lamp cover 22 , and the outer lamp cover 22 is used to scatter the light emitted by the lamp panel 21 .

[0043] The lighting assembly 20 provides light for the camera assembly 30, especially for supplementary lighting at night. The light board 21 provides a light source, and the outer lampshade 22 scatters the light emitted by the light board 21. The outer lampshade 22 is made of a material that can scatter the light source, such as organic glass, polycarbonate and other materials. The outer lampshade 22 of this material turns the strong light emitted by the light board 21 into soft and uniform light, which helps to improve the quality of shooting and avoid the adverse effects of glare on pedestrians. In addition, the outer lampshade 22 can also reduce the direct contact of the external environment with the light board 21, thereby protecting the light board 21.

[0044] In some embodiments, the lighting assembly 20 further includes an inner lampshade 23 , which is located between the lamp panel 21 and the outer lampshade 22 , and the outer surface of the inner lampshade 23 has a brightness enhancement layer.

[0045] The brightening coating can be obtained by electroplating or deposition. In one embodiment, metal chromium is selected as the material of the brightening coating, and the metal chromium is attached to the outer surface of the inner lampshade 23 by electroplating to enhance the reflection of light and improve the lighting effect. The inner lampshade 23 is located between the lamp board 21 and the outer lampshade 22. The light source emitted by the lamp board 21 is fully reflected by the brightening layer of the inner lampshade 23, so that the light distribution is uniform and the brightness is enhanced. The brightened light is scattered in the outer lampshade 22, and finally emits bright soft light, which is conducive to optimizing the imaging effect of the camera assembly 30.

[0046] Please refer to Figure 2 In some embodiments, the outer surface of the housing 10 has a recessed opening 11, and the lighting assembly 20 is installed at the recessed bottom of the recessed opening 11. The shape of the recessed opening 11 is adapted to the shape of the lighting assembly 20, and the lighting assembly 20 is installed at the recessed bottom of the recessed opening 11, so that the lighting assembly 20 does not protrude from the housing 10. When the monitoring device 100 is subjected to external impact, the housing 10 and the lighting assembly 20 are in contact with obstacles, which is conducive to protecting the lighting assembly 20.

[0047] Please refer to Figure 4 In some embodiments, the monitoring device 100 further includes a camera assembly 30 mounted on the housing 10, the height of the center of the camera assembly 30 from the ground is in the range of 230 mm to 270 mm; and the lens of the camera assembly 30 is tilted toward the ground, and the acute angle formed by the central field of view 31 of the lens and the ground is in the range of 12° to 18°;

[0048] The height range between the center of the lens of the camera assembly 30 and the ground is selected between 230mm and 270mm, mainly considering the following aspects: First, the camera assembly 30 is installed within this height range to ensure that it can effectively observe the bottom area, but not too close to the ground, avoiding visual interference from sand and dust, which is conducive to the clarity and integrity of the recorded image. Second, installing the camera assembly 30 at an appropriate height can avoid unnecessary contact or collision with the ground, reduce the risk of damage, and extend the service life of the camera assembly 30. The specific height can be but is not limited to 230mm, 240mm, and 250mm.

[0049] In addition, the angle between the central field of view 31 of the camera assembly 30 lens and the ground is selected to be between 12° and 18°, that is, the degree of downward tilt of the camera assembly 30 is limited, so that the camera assembly 30 can monitor the necessary mid- and high-level environments while being in the low-level visual blind spot, so that the monitoring device 100 can integrate environmental information at different heights, which is conducive to accurate analysis of obstacle avoidance. In one embodiment, the acute angle formed by the installation plane of the camera assembly 30 and the ground is 15°.

[0050] Please refer to the attached Figure 2 In some embodiments, a plane of the housing 10 protrudes from the camera assembly 30. The plane of the housing 10 protrudes from the camera assembly 30. When the monitoring device 100 is subjected to external impact, the plane collides with the obstacle before the camera assembly 30, which is beneficial to protect the camera assembly 30 during the impact.

[0051] Please refer to the attached Figure 2 In some embodiments, a protective shell 40 is installed at the bottom of the monitoring device 100 , and the protective shell 40 is attached to the outer surface of the housing 10 .

[0052] The material of the protective shell 40 can be selected from high-strength rigid materials, such as metal or reinforced plastic, which have excellent impact resistance and can effectively resist the impact of ground obstacles to avoid damage to the bottom of the monitoring device 100. When the monitoring device 100 is patrolling, the protective shell 40 at the bottom can reduce the degree of damage to the monitoring device 100 caused by the impact of obstacles.

[0053] In some embodiments, the bottom of the protective housing 40 has a guide plate 41 that is inclined from top to bottom and inward, and the guide plate 41 is used to guide the monitoring device 100 to be lifted up along the slope when traversing obstacles.

[0054] The function of the guide plate 41 is to enable the monitoring device 100 to smoothly cross the obstacle without directly colliding with the housing 10 when the monitoring device 100 encounters highly uneven terrain or obstacles. When the monitoring device 100 travels to highly uneven terrain or obstacles, the front end of the guide plate 41 first contacts the ground or obstacle, and the driving force of the external device guides the monitoring device 100 to smoothly lift upward when crossing the obstacle along with the inwardly inclined guide plate 41. In this way, the collision between the monitoring device 100 and the ground or obstacles is reduced to a certain extent, which is beneficial to protecting the various components of the monitoring device 100 including the housing 10 and extending the service life; at the same time, the setting of the guide plate 41 is beneficial to smoothly crossing obstacles in complex terrain and improving adaptability.

[0055] Please refer to the attached Figure 5 In some embodiments, the housing 10 has a accommodating cavity inside; the monitoring device 100 also includes a hook lock assembly 50 installed in the accommodating cavity, the hook lock assembly 50 includes a connecting card plate 51, and the connecting card plate 51 is located in the installation area of ​​the accommodating cavity. After the hook lock assembly 50 moves in the first direction under the action of an external force, the connecting card plate 51 leaves the installation area, and the connecting card plate 51 is used to connect the monitoring device 100 and the external device; the reset member 52 is respectively connected to the housing 10 and the hook lock assembly 50, and is configured to reset the connecting card plate 51 after the external force applied to the hook lock assembly 50 is removed.

[0056] Please see attached Figure 1 The autonomous patrol machine 1000 includes a self-moving device 200 and the above-mentioned monitoring device 100, wherein the external device is the self-moving device 200; the monitoring device 100 can be detachably connected to the self-moving device 200, and can complete patrol operations in a preset area under the drive of the self-moving device 200.

[0057] The self-moving device 200 can be a mobile carrier such as a crawler car, a wheeled car, etc. that can have a mounting position for the monitoring device 100, has good mobility and adaptability, and can move freely under different terrains and environmental conditions. The self-moving device 200 is equipped with the monitoring device 100 described in the above embodiment, and the monitoring device 100 can monitor a given area driven by the self-moving device 200. Such a design enables the autonomous patrol machine 1000 to independently complete monitoring tasks, reduces manpower input, and enables monitoring tasks to be completed quickly and efficiently in different scenarios.
