Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 19, an embodiment of the present invention discloses a video camera, which includes a body main body 100, a wide-angle lens assembly 200, a non-wide-angle lens assembly 300, and a main board 800, wherein the wide-angle lens assembly 200 and the non-wide-angle lens assembly 300 are mounted on the body main body 100. Further, in order to improve the expandability of the camera, both the wide-angle lens assembly 200 and the non-wide-angle lens assembly 300 may be detachably mounted to the body main body 100, and thus different wide-angle lens assemblies 200 and non-wide-angle lens assemblies 300 may be freely combined. The main board 800 is provided in the main body 100, and the operating state of the camera can be controlled by the main board 800.

Wide angle lens assembly 200 includes a first lens mount 210 and a wide angle lens 220 mounted on first lens mount 210, and non-wide angle lens assembly 300 includes a second lens mount 310 and a non-wide angle lens 320 mounted on second lens mount 310. The first lens holder 210 is located above or below the second lens holder 310, the first lens holder 210 has a first arc surface 211, the wide-angle lens 220 is installed on the first arc surface 211, the second lens holder 310 has a second arc surface 313, the non-wide-angle lens 320 is installed on the second arc surface 313, and the radian of the first arc surface 211 is equal to the radian of the second arc surface 313. Optionally, the radians of the first arc surface 211 and the second arc surface 313 are both 2 pi/3-2 pi, so that the wide-angle lens 220 can be flexibly installed at any position of the first arc surface 211 according to actual requirements, and the non-wide-angle lens 320 can be flexibly installed at any position of the second arc surface 313 according to actual conditions, thereby meeting diversified requirements of users.

Correspondingly, the radian of the non-wide-angle lens group is 2 pi/3-2 pi, and the radian of the wide-angle lens group is 2 pi/3-2 pi.

Specifically, the wide-angle lens 220 included in the wide-angle lens assembly 200 has a short focal length and a large field angle, and the non-wide-angle lens 320 included in the non-wide-angle lens assembly 300 has a different focal length from the wide-angle lens 220, so that the two can monitor scenes with different depths of field. Therefore, the camera adopting the structure can meet the requirement of a user on the condition that the camera can monitor a plurality of scenes with different depths of field simultaneously.

Alternatively, in one embodiment, the focal length of wide angle lens 220 may be selected to be 4mm or 6mm, and the focal length of non-wide angle lens 320 may be 8mm or 12 mm. In another embodiment, wide-angle lens 220 has a focal length of 2.8mm and non-wide-angle lens 320 has a focal length of 6 mm. Of course, the focal lengths of the wide-angle lens 220 and the non-wide-angle lens 320 are not limited thereto, and other choices may be adopted according to the needs of the user and the layout of the overall structure, which is not limited herein.

In the embodiment of the present invention, the non-wide-angle lens assembly 300 may be further configured as a telephoto lens assembly, and correspondingly, the non-wide-angle lens 320 may be configured as a telephoto lens. The telephoto lens has a large focal length, and is suitable for photographing a distant object. It should be noted that the subsequent embodiments described herein can be applied to the telephoto lens assembly.

In addition, the wide-angle lens 220 and the non-wide-angle lens 320 are respectively mounted on the first lens holder 210 and the second lens holder 310 and then mounted on the body main body 100, so that the camera has a more compact structure, occupies a smaller space, and is simpler to assemble.

The wide angle lens group has a field of view covering the field of view of the non-wide angle lens group. The wide-angle lens group can meet the requirement of large-range shooting, and the non-wide-angle lens group can realize the enlarged shooting of details in the large range, for example, a local scene in the field range of the wide-angle lens group is monitored, so that the field range of the wide-angle lens group covers the field range of the non-wide-angle lens group, the function of the non-wide-angle lens group can be fully exerted, the requirements of large-range shooting and detail acquisition are better considered, and the diversified shooting requirement of a user is better met.

As shown in fig. 9, in order to optimize the shooting effect of the camera, the embodiment of the invention sets the horizontal field angle α 1 of the wide-angle lens 220 to be 40 to 90 °, and sets the vertical field angle α 2 thereof to be 90 to 150 °. Similarly, as shown in fig. 10, the horizontal angle of view β 1 of the non-wide-angle lens 320 may be set to 10 to 70 °, and the vertical angle of view β 2 thereof may be set to 40 to 90 °.

In a further embodiment, wide-angle lens 220 has a horizontal field angle α 1 of 55 °, a vertical field angle α 2 of 102 °; the non-wide-angle lens 320 has a horizontal angle of view β 1 of 30 ° and a vertical angle of view β 2 of 53 °.

In an alternative structure, as shown in fig. 5, the body 100 includes a U-shaped portion 110 and an arc portion 120, and both ends of the arc portion 120 are connected by the U-shaped portion 110 to form a ring structure. At this time, the inner space of the body main body 100 is large due to the U-shaped portion 110, and the structure of the arc portion 120 corresponds to the first arc surface 211 of the first lens holder 210 and the second arc surface 313 of the second lens holder 310, so that the structure of the entire video camera is more compact and the occupied space is reduced. The radian of the arc-shaped part 120 can be set to be 2 pi/3-2 pi, so that more selectable positions are provided for arranging the lens.

The U-shaped portion 110 and the arc-shaped portion 120 are made of various materials and connected in various forms. In one structure, the U-shaped portion 110 and the arc-shaped portion 120 may be made of a metal material and integrally formed, and at this time, the U-shaped portion 110 and the arc-shaped portion 120 form a non-detachable structure, so that the structural strength of the entire body main body 100 is higher. At this time, the heights of the U-shaped portion 110 and the arc-shaped portion 120 may be equal, and the top and bottom edges of both may be flush. The structure of the whole body main body 100 can be more regular due to the arrangement, the assembly of the body main body 100 is more convenient, and meanwhile, the aesthetic property of the camera is improved. Optionally, the height of the U-shaped portion 110 and the height of the arc-shaped portion 120 are both 200mm to 400 mm.

In another structure, as shown in fig. 20 to 28, the arc-shaped portion 120 may be configured as a split structure, which may specifically include a plurality of window brackets 150, each window bracket 150 is relatively independent and detachably mounted on the U-shaped portion 110, the window bracket 150 is also provided with the first through hole 121 facing the wide-angle lens 220 for allowing the wide-angle lens 220 to pass light, and the second through hole 122 facing the non-wide-angle lens 320 for allowing the non-wide-angle lens 320 to pass light, and one surface of the window bracket 150 away from the wide-angle lens assembly 200 and the non-wide-angle lens assembly 300 is configured as an arc surface. The camera may further include a transparent window 610, and the first through hole 121 and the second through hole 122 are both provided with the transparent window 610, and the transparent window 610 may allow light to pass through on one hand and may protect the lens on the other hand. Alternatively, the number of the window holders 150 may be three, and the arc degree of the arc surface of each window holder 150 may be pi/3 to 2 pi/3. In addition, the transparent window 610 may be fixed in the first through hole 121 or the second through hole 122 by dispensing, so as to fix the transparent window 610 and improve the fixing reliability of the transparent window 610.

The window supports 150 may be sequentially arranged along the arc length direction of the arc portion 120, and the arc surfaces of the window supports 150 are spliced into an arc whole surface, so as to form a larger arc surface structure, so that the transparent windows 610 are arranged according to the arrangement mode of the lenses. Optionally, the arc of the entire arc is pi 3/4-pi.

In order to reduce the weight of the window frame 150, the window frame 150 may be a plate-shaped structure, but the structural strength of the plate-shaped structure itself is poor, so in order to ensure the structural strength of the window frame 150, the window frame 150 includes an arc plate 151, a first plate 152 and a second plate 153, the arc plate 151 has the foregoing arc surface, the first plate 152 and the second plate 153 are disposed at two opposite ends of the arc plate 151 along the height direction of the arc part 120, and the three form a lens accommodating cavity. The lens receiving cavity formed therein can receive at least a portion of the wide-angle lens 220 and the non-wide-angle lens 320, thereby increasing the structural strength of the window frame 150 and reducing the space occupied by the entire camera.

The side of the window mount 150 facing the wide angle lens assembly 200 and the non-wide angle lens assembly 300 has an annular rim 154, and the annular rim 154 is flat facing the inner surface 154a of the wide angle lens assembly 200 and the non-wide angle lens assembly 300. Viewing the window frame 150 from the side of the window frame 150 facing the wide angle lens assembly 200 and the non-wide angle lens assembly 300, the arcuate plate 151 thereof is recessed away from the wide angle lens assembly 200 and the non-wide angle lens assembly 300, such that the side thereof facing the wide angle lens assembly 200 and the non-wide angle lens assembly 300 forms an annular rim 154, the annular rim 154 surrounding the lens receiving cavity as previously described. With the inner surface 154a of the annular rim 154 being flat, the window bracket 150 is simpler to construct and easier to machine, while also facilitating its engagement with the U-shaped portion 110.

The transparent windows 610 may be arranged in a sheet-like configuration with at least one of the transparent windows 610 being parallel to the inner surface 154a of the annular rim 154. This configuration can simplify the structure of the transparent window 610 and simplify the installation process of the transparent window 610. It should be noted that the transparent window 610 may be perpendicular to the optical axis of the corresponding wide-angle lens 220 or non-wide-angle lens 320.

Further, the arc portion 120 may further include a plurality of bracket mounting frames 155, and the bracket mounting frames 155 are sequentially connected along the arc length direction of the arc portion 120. The number of the bracket mounting frames 155 may be the same as the number of the window brackets 150, so that the plurality of window brackets 150 are detachably mounted to the plurality of bracket mounting frames 155 one by one. Specifically, at least a portion of the bracket mounting frame 155 may be mounted to the U-shaped portion 110. As mentioned above, the inner surface 154a of the annular rim 154 is planar, so that the bracket mounting frame 155 can extend within the inner surface 154a, and the inner surface 154a of the annular rim 154 is parallel to the plane of the bracket mounting frame 155. Window support 150 installs behind support mounting frame 155, and both laminate basically for the clearance between the two is less, and impurity such as dust is difficult to get into in the camera.

The effect is still less than ideal if only a snug fit between the window frame 150 and the frame mounting 155 is relied upon to prevent contaminants from entering the camera. To this end, the arcuate portion 120 may further include a sealing ring 160, with the inner surface 154a of the annular rim 154 sealingly engaging the bracket mounting frame 155 via the sealing ring 160. This sealing washer 160 can receive the pressing force that comes from window support 150 and support mounting frame 155, and then takes place to warp and applys reaction force to window support 150 and support mounting frame 155, then with window support 150 and support mounting frame 155 in close contact with, reaches better sealed effect.

To facilitate the assembly and disassembly of the window bracket 150, the window bracket 150 may be secured to the bracket mounting frame 155 via fasteners. Optionally, the arc-shaped portion 120 further includes a fixing protrusion 170 integrally formed on the bracket mounting frame 155, the fixing protrusion 170 extends toward the inside of the bracket mounting frame 155 and is provided with a threaded hole, a fastening hole is formed in the window bracket 150, and a fastening member passes through the fastening hole and is in threaded engagement with the threaded hole to fix the window bracket 150 and the bracket mounting frame 155. With the fixing protrusion 170, the screw hole can be easily formed, and the size of the arc portion 120 at other positions does not need to be increased, so that the structure of the body 100 is more flexible.

In order to improve the mounting strength between the window bracket 150 and the bracket mounting frame 155, a plurality of fixing protrusions 170 may be provided, and each fixing protrusion 170 may be provided along an edge of the bracket mounting frame 155.

The plurality of window frames 150 include a first frame 150a, a second frame 150b and a third frame 150c, an included angle between an inner surface 154a of the first frame 150a and an inner surface 154a of the second frame 150b is a first included angle θ 1, an included angle between an inner surface 154a of the second frame 150b and an inner surface 154a of the third frame 150c is a second included angle θ 2, and the first included angle θ 1 is equal to the second included angle θ 2. That is, the first bracket 150a and the third bracket 150c are symmetrically disposed on opposite sides of the second bracket 150b, and thus adapt to the distribution of the wide-angle lens 220 and the non-wide-angle lens 320, so that the intervals between the first bracket 150a, the second bracket 150b, and the third bracket 150c and each of the wide-angle lens 220 and the non-wide-angle lens 320 are more uniform.

Alternatively, the first included angle θ 1 and the second included angle θ 2 may be set to 100 ° to 130 °.

The wide-angle lens 220 and the non-wide-angle lens 320 may be provided in one or more than one. In order to increase the coverage of the camera, the embodiment of the invention sets the wide-angle lens 220 to be plural, and at least a part of the plural wide-angle lenses 220 may be uniformly arranged along the arc length direction of the arc-shaped portion 120 (when the arc-shaped portion 120 includes the window frame 150, the arc length direction may be the arc length direction of the arc surface of the window frame 150) to form the wide-angle lens group. Correspondingly, a plurality of first through holes 121 may be formed in the arc portion 120, the plurality of first through holes 121 are uniformly arranged along the arc length direction of the arc portion 120 to form a first hole group, and the plurality of wide-angle lenses 220 in the wide-angle lens group are directly opposite to the plurality of first through holes 121 of the first hole group.

Similarly, the non-wide-angle lenses 320 may also be provided in plurality, and the plurality of non-wide-angle lenses 320 are uniformly arranged along the arc length direction of the arc-shaped portion 120 to form a non-wide-angle lens group. Correspondingly, the arc-shaped portion 120 is provided with a plurality of second through holes 122, the plurality of second through holes 122 are uniformly arranged along the arc length direction of the arc-shaped portion 120 to form a second hole group, and the plurality of non-wide-angle lenses 320 in the non-wide-angle lens group are directly opposite to the plurality of second through holes 122 of the second hole group.

Since the wide-angle lens 220 has a relatively large field angle and the non-wide-angle lens 320 has a relatively small field angle, the aperture of the first through hole 121 may be larger than that of the second through hole 122 in order to match the sizes of the first through hole 121 and the second through hole 122 with the field angles of the wide-angle lens 220 and the non-wide-angle lens 320, thereby ensuring the amount of light entering and avoiding wasting the first through hole 121 and the second through hole 122. In addition, the hole spacing between the adjacent first through holes 121 can be set to 70-100 mm, and the hole spacing between the adjacent second through holes 122 can be set to 160-180 mm.

The non-wide-angle lens assembly 300 may be provided only one, and may be located above or below the wide-angle lens assembly 200. To further increase the coverage of the camera, two non-wide angle lens assemblies 300 may be provided, the two non-wide angle lens assemblies 300 being located on opposite sides of the wide angle lens assembly 200. That is, the non-wide angle lens assembly 300 is disposed both above and below the wide angle lens assembly 200. In this case, the two sets of second holes are also formed in the arc-shaped portion 120, and the two sets of second holes are respectively located on two opposite sides of the first hole set.

In order to simplify the lens mounting operation while satisfying the above-described photographing requirements, the wide-angle lens 220 may be provided with a first mounting surface 221, the first mounting surface 221 being disposed vertically, with an optical axis of the wide-angle lens 220 being perpendicular to the first mounting surface 221, i.e., the optical axis extending in a horizontal direction. The non-wide angle lens 320 is provided with a second mounting surface 321, and in the non-wide angle lens group, the second mounting surface 321 of the non-wide angle lens 320 is disposed obliquely upward or obliquely downward with respect to the first mounting surface 221 of the wide angle lens 220. Because the field of view of the wide-angle lens 220 overlaps with that of the non-wide-angle lens 320 in the vertical direction, the overlapping portion can be reduced as much as possible by such an inclined arrangement, so that the range covered by the camera can be enlarged as much as possible without increasing the number of lenses.
