Fig. 2 is a side view of the housing assembly of fig. 1. As shown in fig. 1 and 2, the present invention provides a housing assembly 100 of a camera 1 for monitoring an overhead area, comprising: a first housing 10 and a second housing 20, wherein,
the first casing 10 includes a first sidewall 11, a second sidewall 12 corresponding to the first sidewall 11, and a plane member 13 connecting the first sidewall 11 and the second sidewall 12, wherein a front region of the first sidewall 11 or the second sidewall 12 extends longitudinally more downward than a rear region, and the front region of the first sidewall 11 or the second sidewall 12 forms a sharp-angled shape of an acute angle;
the second casing 20 includes a third sidewall 21, a fourth sidewall 22 corresponding to the third sidewall 21, and a circular arc-shaped curved surface member 23 connecting the third sidewall 21 and the fourth sidewall 22, wherein the third sidewall 21 is detachably connected to a front region of the first sidewall 11, and the fourth sidewall 22 is detachably connected to a front region of the second sidewall 12;
when the first casing 10 is connected to the second casing 20, the first casing 10 and the second casing 20 form an accommodating space for arranging the camera 1, wherein a front end surface of the front cover assembly 2 of the camera 1 does not exceed a front end surface of the first casing 10 and is spaced from the front end surface of the first casing 10 by a first distance L1, and a front end surface of the front cover assembly 2 of the camera 1 does not exceed a front end surface of the second casing 20 and is spaced from the front end surface of the second casing 20 by a second distance L2, so that when the camera 1 is used for monitoring an overhead area, a top of the camera and an upper portion of the front end surface of the front cover assembly 2 are shielded by the first casing 10, and a lower portion of the front end surface of the front cover assembly 2 is shielded by the second casing 20.
The first housing 10 is installed above the camera 1 and is used for shielding the top and two sides of the camera 1. Specifically, the first casing 10 is composed of a pair of opposing first and second side walls 11 and 12, and a planar member 13 connected between the first and second side walls 11 and 12, and forms a U-shaped structure with an opening facing downward to cover the upper side of the camera 1. The planar member 13 is used to protect the top of the camera 1, and the first side wall 11 and the second side wall 12 respectively form protection at both sides of the camera 1.
In the present embodiment, the first sidewall 11 and the second sidewall 12 may have the same structure, and only the first sidewall 11 is taken as an example in the following description. Similarly, the third side wall 21 and the fourth side wall 22 may have the same structure.
As shown in fig. 2, when the first housing 10 is attached to the video camera 1, the front end surface of the front cover assembly 2 of the video camera 1 does not protrude beyond the front end surface of the first housing 10. Specifically, the front end surface of the front cover assembly 2 may not extend beyond the front end surface 11a of the first side wall 11 and be spaced apart from the front end surface of the first housing 10 by the first distance L1, and then the first side wall 11 and the second side wall 12 may shield light and foreign substances from both sides of the camera 1. The front face of the planar member 13 may be flush with the front faces of the first and second side walls 11, 12. Alternatively, the planar member 13 may have a protrusion 13a beyond the front face 11a of the first side wall 11 to protect the camera head assembly of the camera 1 from the top and obliquely forward of the front cover assembly 2 of the camera 1, since light from above the camera 1 is more and more likely to cause glare, and there is a greater chance of falling objects from above the camera 1.
The second housing 20 is located below the camera 1, and shields light and foreign substances from the bottom of the camera 1. Wherein the second housing 20 includes: two opposite side wall components, namely a third side wall 21 and a fourth side wall 22, and a circular arc curved surface component 23 fixedly connected with the side wall components 21 and 22. The circular arc curved surface component 23 and the side wall components 21 and 22 form a containing space which is opened towards the lens component 3 of the camera 1.
As shown in fig. 2, when the second housing 20 is mounted to the camera 1, the front surface of the front cover assembly 2 of the camera 1 does not exceed the front surface of the second housing 20 and is spaced apart from the front surface of the second housing 20 by a second distance L2, so that the second housing 20 can shield light and foreign substances from the bottom of the front cover assembly 2.
The first housing 10 and the second housing 20 are detachably fixed, and when the first housing 10 and the second housing 20 are connected, a light entrance area adapted to a field angle is formed at a front end, wherein ambient light is transmitted into the lens assembly 3 through the light entrance area.
Fig. 3a and 3b are schematic diagrams illustrating the field angle of a camera for monitoring a high-altitude area. The field angles include a vertical field angle and a horizontal field angle. Where fig. 3a shows the range of horizontal field angles, as shown in fig. 3a, the spacing between the first and second side walls 11, 12 of the first housing 10 should be adapted to the angle of the horizontal field angle. Fig. 3b shows the range of the vertical field of view, and as shown in fig. 3b, the vertical distance between the front end face of the first housing 10 and the front end face of the second housing 20 is adapted to the angle of the vertical field of view.
The second housing 20 is detachably connected to the first housing 10, so that the first housing 10 can be used alone, and when there is no light or foreign matter from the bottom of the camera in the use environment of the camera 1, the second housing 20 can be detached from the first housing 10, and the camera 1 can be protected and shaded only with the first housing 10.
Further, the front region of the first side wall 11 and/or the second side wall 12 extends longitudinally more downward than the rear region, and the front region of the first side wall 11 and/or the second side wall 12 forms a sharp-angled shape of an acute angle to shield light from the bottom from both sides of the camera 1.
In this embodiment, the first housing 10 and the second housing 20 enclose to form an accommodating space for installing the camera 1, the lens assembly 3 of the camera 1 can be comprehensively protected from the top, two sides, and bottom of the front housing assembly 2 at the front end of the camera 1, and by setting the relative positions of the camera 1 and the housing assembly 100, the front end surfaces of the first housing 10 and the second housing 20 can be adapted to the field angle boundary of the camera 1, so that the camera can be protected from being damaged by falling objects, external light which easily causes glare can be shielded, and the field of view of the camera cannot be affected.
Further, the circular arc-shaped curved surface component 23 and the side wall components 21 and 22 form a circular accommodating space together, so that light and foreign matters can be shielded, and even if the foreign matters enter the second shell 20 from the opening, the accommodating space below the front cover component 2 can be formed to be lower than the accommodating space of the lens component 3, so that the lens is prevented from being shielded due to the accumulation of the foreign matters.
Therefore, in a preferred embodiment, the circular arc curved surface member 23 has a semicircular shape in cross section with a central angle of not less than 180 °, and the radius R of the semicircular shape is determined by the angle of view of the camera 1 so that the lower boundary of the vertical angle of view of the camera is not lower than the circular arc curved surface member 23. That is, the circular arc-shaped curved surface component 23 is located outside the range of the vertical field angle of the camera to avoid obstructing the field of view of the camera.
Specifically, in a preferred embodiment, as shown in fig. 1 and 2, the third and fourth side walls 21 and 22 of the second housing 20 have a connection area that is form-fitted to the front area of the first housing 10, and the connection area of the second housing 20 and the front area of the first housing 10 are supported via the catch 14.
Wherein the front area of the first side wall 11 has a pointed shape formed by a first side wall front end surface 11a and a first side wall part lower end surface 11b, wherein the first side wall front end surface 11a is perpendicular to the horizontal plane and the first side wall part lower end surface 11b extends longitudinally downwards from the intersection point 11c of the front area and the rear area of the first housing 10 towards the first side wall front end surface 11 a.
Correspondingly, the connection area of the third side wall 21 is formed by a third side wall vertical rear end face 21a and a third side wall inclined rear end face 21b, wherein the third side wall vertical rear end face 21a is connected with the lower portion of the first side wall front end face 11a, the third side wall inclined rear end face 21b is connected with the first side wall part lower end face 11b, and the third side wall inclined rear end face 21b corresponds in length to the first side wall part lower end face 11 b.
Wherein the front area of the first housing 10 corresponds to the position of the front housing assembly 2 of the camera 1, the pointed shape of the front area of the first side wall 11 is formed by a first side wall front end face 11a and a first side wall portion lower end face 11b, the first side wall portion lower end face 11b being a section of the first side wall lower end face from the intersection point 11c of the front area and the rear area of the first housing 10 to the position where the first side wall front end face 11a meets. The front region has a more downwardly longitudinally extending sharp corner than the rear region to provide a greater shaded area for the location of the front housing assembly 2 and to provide an area for easy attachment for installation of the second housing 20.
Specifically, as shown in fig. 1, the connection region of the third sidewall 21 further includes a flange (not shown in the drawings) extending from the vertical rear end surface 21a of the third sidewall and the inclined rear end surface 21b of the third sidewall, the front region of the first sidewall 11 further includes a slot 24 disposed at the inner edge of the front end surface 11a of the first sidewall and the lower end surface 11b of the first sidewall, and the flange is received in the slot 24 to connect the second housing 20 and the first housing 10, and further fixed by the clip 14. The clip 14 may be disposed at one or both ends of the slot 24.
In a preferred embodiment, the inclination rate of the lower end face 11b of the first side wall portion corresponds to the vertical field angle of the camera.
In the embodiment shown in fig. 2, further, the circular arc-shaped curved surface component 23 and the side wall components 21 and 22 form a circular accommodating space together, which not only can shield light and foreign matters, but also can form an accommodating space lower than the lens component 3 below the front cover component 2 even if the foreign matters enter the second housing 20 from the opening, so as to avoid the shielding of the lens caused by the accumulation of the foreign matters.
Therefore, when the second housing 20 is connected to the first housing 10, the vertex of the sharp corner is spaced apart from the center O of the circular arc curved component 23 by a third distance L3, and the front region of the first housing 10 exceeds the center O of the circular arc curved component 23. The position of the center O of the circular arc-shaped curved surface component 23 corresponds to the position of the foreign matter accumulation in the second housing 20, and the backward movement of the position can avoid the foreign matter accumulation from obstructing the view range of the lens component 3.
Further, the center O of the circular arc curved surface assembly 23 exceeds the front end surface of the front shell assembly 2 by a fourth distance L4, and the bottom end surface of the circular arc curved surface assembly 23 is lower than the bottom end surface of the front cover assembly 2. Therefore, the accumulation point of the accommodating space formed by the combination of the arc-shaped curved surface component 23 and the side wall components 21 and 22 forms a distance with the lens component 3 positioned in the front shell component 2 in the horizontal direction and the vertical direction, thereby avoiding the obstruction of the view range.
As shown in fig. 2, in a preferred embodiment, the third sidewall upper end surface 21c of the third sidewall 21 forms a declined first included angle α with the first sidewall front end surface 11a of the first sidewall 11, which corresponds to the vertical field angle of the camera.

Therefore, when the second housing 20 is fixedly connected to the camera 1, the center O of the circular arc curved surface component 23 exceeds the front end surface of the front housing component 2 by the fourth distance L4, the center points of the two ends of the opening are located below the central axis of the lens component 3 in the longitudinal direction, and the bottom end surface of the circular arc curved surface component 23 is lower than the bottom end surface of the front cover component 2. Therefore, the accumulation point of the accommodating space formed by the combination of the arc-shaped curved surface component 23 and the side wall components 21 and 22 forms a distance with the lens component 3 positioned in the front shell component 2 in the horizontal direction and the vertical direction, thereby avoiding the obstruction of the view range.
