[0043] Now, each exemplary embodiment will be described more fully with reference to the accompanying drawings.

[0044] As Figures 1 to 3 shown, an embodiment of the utility model provides a dome camera, including:

[0045] A base 10, the base 10 having a first receiving portion 11;

[0046] A transparent cover 20, the transparent cover 20 being assembled to the first receiving portion 11, and the transparent cover 20 and the base 10 being joined to form a receiving cavity;

[0047] A support assembly 31 and a lens assembly 32, the lens assembly 32 being assembled in the receiving cavity via the support assembly 31;

[0048] The lens assembly 32 includes a second receiving portion, wherein a magnetic element 324 is provided in the second receiving portion. When a preset magnetic force is applied to the outer surface of the transparent cover 20, the magnetic element 324 is affected by the preset magnetic force, so that the lens assembly 32 moves, and then moves in the same direction as the preset magnetic force, so that the optical axis of the lens assembly 32 moves to a preset angle.

[0049] In this embodiment, the hemispherical camera forms a closed receiving cavity by the transparent cover 20 and the base 10. The lens assembly 32 is located in the receiving cavity, and the lens assembly 32 is encapsulated in the receiving cavity to ensure the use environment of the lens assembly 32 and prevent dust, water vapor, etc. from entering the receiving cavity. When it is necessary to adjust the optical axis of the lens assembly 32, the lens assembly 32 is guided in a magnetic attraction manner from the outer surface of the receiving cavity to drive the lens assembly 32 to move relative to the support assembly 31, so that the optical axis of the lens assembly 32 moves to a preset angle.

[0050] In this embodiment, the hemispherical camera can be manually adjusted from the outside in a magnetic attraction manner with a low cost, without disassembling the transparent cover, preventing dust and water vapor from entering the product cavity, and can significantly simplify the adjustment process, and there is no need to install a motor, thus saving costs.

[0051] Wherein, the optical axis direction of the lens assembly 32 is defined as the first axis L. The lens assembly 32 includes a main body 321 and a lens group 322. The second receiving portion is provided on the main body 321. The lens group 322 is partially arranged inside the second receiving portion and partially extends out of the second receiving portion. The second receiving portion defines the first axis L, wherein the first axis L is coaxial with the optical axis of the lens group 322.

[0052] Wherein, the main body 321 is configured to include a magnetic element 324.

[0053] In one embodiment, the number of the magnetic elements 324 is 2, and the magnetic elements 324 are symmetrically arranged about the first axis L, so that the lens assembly can be adjusted in direction with the first axis L as the center.

[0054] Optionally, the number of the magnetic elements 324 is greater than 2, and at least 2 magnetic elements 324 are arranged at positions symmetric about the first axis L. In a preferred example, the connecting lines of the center points of all the magnetic elements 324 form an arc shape and are arranged in a form surrounding the lens assembly.

[0055] Wherein, the magnetic element 324 is a magnet, and the second receiving portion is set as a groove 325 for receiving the magnetic element 324. And the element applying the preset magnetic force outside the receiving cavity can also be a magnet paired with the magnetic element 324.

[0056] Optionally, the number of the magnetic elements 324 is multiple, and the magnetic elements 324 are sequentially arranged on the main body 321 in an arc shape.

[0057] In one embodiment, the center of the arc defined by the position where the magnetic element 324 is disposed on the main body 321 is collinear with the first axis L.

[0058] The radius of the hemispherical transparent cover 20 is R and the thickness is 2 mm. Magnets are installed at three points on the main body 321 of the lens assembly 32 inside the hemisphere. The three points are distributed on a semi-circular arc with the lens center normal as the center line. Points a and c are the two ends of the arc, and point b is the midpoint of the arc. The central normal of the cylindrical magnet passes through the center of the spherical part of the transparent cover and the angle with the lens center normal is less than 60 degrees. The distance from the center of the outer end face of the magnet to the inner wall of the transparent cover does not exceed 1 mm, and the surface can be covered with a thin flannel cloth 45 to prevent scratching the transparent cover.

[0059] As Figures 4a to 6b shown, another embodiment of the present utility model further provides a hemispherical camera system, including:

[0060] A base 10, the base 10 having a first receiving portion 11;

[0061] A transparent cover 20, the transparent cover 20 being assembled to the first receiving portion 11, and the transparent cover 20 and the base 10 are combined to form a receiving cavity. Among them, the transparent cover 20 has a spherical shape;

[0062] A support assembly 31 and a lens assembly 32, the lens assembly 32 being assembled in the receiving cavity via the support assembly 31;

[0063] The lens assembly 32 includes a main body 321 and a lens group 322. The main body 321 is located outside the lens group 322. Among them, the main body 321 is configured such that: the main body 321 includes a first magnetic member 41;

[0064] A handle 40, the handle 40 including a second magnetic member 42;

[0065] The lens assembly 32 and the handle 40 are configured such that when the handle 40 abuts against the outer surface of the transparent cover 20, the second magnetic member 42 of the handle 40 generates a preset magnetic force with the first magnetic member 41 of the main body 321, and the main body 321 moves under the action of the preset magnetic force so that the optical axis of the lens assembly 32 moves to a preset angle.

[0066] The handle 40 is used to apply a preset magnetic force outside the accommodation cavity and facilitate the operation of the user. In this embodiment, the hemispherical camera forms a closed accommodation cavity by the transparent cover 20 and the base 10. The lens assembly 32 is located inside the accommodation cavity and is encapsulated in the accommodation cavity to ensure the use environment of the lens assembly 32 and prevent dust, water vapor, etc. from entering the accommodation cavity. When the optical axis of the lens assembly 32 needs to be adjusted, the lens assembly 32 is guided magnetically from the outer surface of the accommodation cavity to drive the lens assembly 32 to move relative to the support assembly 31, so that the optical axis of the lens assembly 32 moves to a preset angle.

[0067] In this embodiment, the hemispherical camera can be manually adjusted from the outside in a magnetic attraction manner with low cost, without disassembling the transparent cover, preventing dust and water vapor from entering the product cavity, and can significantly simplify the adjustment process, and there is no need to install a motor, thus saving costs.

[0068] In one embodiment, the number of the first magnetic members 41 is 2, and the first magnetic members 41 are symmetrically arranged about the optical axis of the lens assembly 32;

[0069] The handle 40 includes: a grip 43 and a pair of arms 44 symmetrically extending from the end of the grip 43, and the second magnetic member 42 is installed at the end of the arm 44;

[0070] Wherein the handle 40 is configured such that when the second magnetic member 42 is aligned with the first magnetic member 41 correspondingly, the grip 43 is collinear with the optical axis of the lens assembly 32.

[0071] Wherein, the number of the first magnetic members 41 is greater than 2, and the first magnetic members 41 are arranged in an arc shape on the main body 321;

[0072] Wherein, it includes at least 2 first magnetic members 41 arranged at positions symmetric about the optical axis, and 1 first magnetic member 41 arranged at the midpoint of the arc;

[0073] The handle 40 includes: a grip 43 and a pair of arms 44 symmetrically extending from the end of the grip 43, and the second magnetic member 42 is installed at the ends of the arm 44 and the grip 43.

[0074] Wherein, the center of the circle corresponding to the arc is collinear with the center of the lens group 322, and the radius of the arc is greater than the radius of the lens group 322.

[0075] For example, if the number of the first magnetic members 41 is three, then the handle 40 also includes three second magnetic members 42 to be used for guiding the movement of the lens assembly 32 by attracting the first magnetic members 41.

[0076] For the corresponding hemisphere, there are also three points 42a, 42b, and 42c on the handle, where a second magnetic part 42 is installed. The central normal of the second magnetic part 42 coincides with the central normal of the first magnetic part inside the hemisphere. The distance between the center of the outer side of the second magnetic part and the outer side of the transparent cover does not exceed 0.5 mm, and the surface needs to be covered with flannelette to prevent scratching the transparent cover.

[0077] The adjustment method when the dome camera is ceiling-mounted is as Figures 7a to 7c shown. It is necessary to correspond the handle 40 to the positions of the three groups of first magnetic parts inside the hemisphere one by one. First, adjust the pitch (T) direction to the required angle, and then adjust the optical axis (R) direction to the required angle to complete the adjustment.

[0078] The adjustment method when the dome is wall-mounted is as Figure 8 shown. Correspond the handle 40 to the positions of the three groups of first magnetic parts inside the hemisphere one by one. First, adjust the pitch (T) direction, and then adjust the optical axis (R) direction to the required angle. Among them, since the 42a point is close to the dome housing and the T-direction adjustment cannot be directly performed, the handle 40 is first removed, the corresponding relationship of the first magnetic part positions is adjusted and then adsorbed. Adopt the sequential movement method. For example, 42a on the handle corresponds to a in the first magnetic part, 42b on the handle corresponds to b in the first magnetic part, and 42c on the handle corresponds to c in the first magnetic part. When moving to a position where the T-direction adjustment cannot be performed, the 42a point on the handle can correspond to b in the first magnetic part, the 42b point corresponds to c point, and the 42c point is left empty. Then adjust the T direction to the required angle to complete the adjustment.

[0079] The above has been described with the first magnetic part 41 being discretely arranged in a dot pattern on the main body 321 of the lens assembly. It can be understood that the first magnetic part 41 can also be formed into a strip-shaped or belt-shaped integral part, where the first magnetic part 41 has the same curvature as the main body 321 and is symmetrically arranged about the optical axis of the lens assembly 32. For example, the first magnetic part 41 can be formed into a semi-circular arc shape.

[0080] Correspondingly, the handle 40 can still adopt the form of discrete dot distribution as Figure 5 shown, or can also adopt the form of a semi-circular arc-shaped strip or belt-shaped magnetic part corresponding to the first magnetic part 41 to increase the magnetic force.

[0081] In this embodiment, the dome camera can be manually adjusted from the outside in a magnetic attraction manner with a low cost without disassembling the transparent cover, preventing dust and water vapor from entering the product cavity, and can significantly simplify the adjustment process. There is no need to install a motor, thus saving costs.

[0082] The series of detailed descriptions listed above are only specific descriptions of the feasible implementation modes of the present utility model, rather than being used to limit the protection scope of the present utility model. Any equivalent implementation schemes or changes made without departing from the technical spirit of the present utility model, such as the combination, division or repetition of features, shall be included within the protection scope of the present utility model.
