[0049] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific embodiments of the invention are now described with reference to the accompanying drawings, in which the same reference numerals represent the same parts.

[0050] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0051] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0052] In order to solve the technical problem of large size of cameras in the prior art, an object of the present invention is to provide a camera which realizes miniaturization of the whole device by rearranging the lens assembly, the power board and the fill light board.

[0053] Figure 1 It is a schematic diagram of the external structure of the first embodiment of the camera of the present invention. Figure 2 1 is a cross-sectional view of a first embodiment of a camera of the present invention. Figure 1 and Figure 2 As shown, one embodiment of the present invention provides a camera, comprising:

[0054] The outer shell is composed of a front shell 11 and a rear shell 12. The front surface of the front shell 11 is provided with a lens window 13 and a fill light window 14;

[0055] The lens assembly 20 is installed in the housing. The lens assembly 20 includes a main board 21 and a lens 22 protruding from the main board 21. The lens 22 takes pictures through the lens window 13.

[0056] A fill light assembly 30, the light of the fill light assembly 30 is emitted from the fill light window 14 to the shooting area of ​​the lens assembly 20;

[0057] A power board 40, the power board 40 provides power to the lens assembly 20 and the fill light assembly 30, the fill light assembly 30 is mounted on the power board 40, and the power board 40 is provided with a through hole 41 for the lens 22 to pass through;

[0058] The power board 40, the main board 21, and the front surface of the front shell 11 are arranged in parallel, the power board 40 is closer to the front surface of the front shell 11 than the main board 21, and the front end of the lens 22 is closer to the front surface of the front shell 11 than the power board 40, and the thickness of the outer shell is determined by the distance between the main board 21 and the front surface of the front shell 11.

[0059] In the camera of this embodiment, the outer shell is composed of a front shell 11 and a rear shell 12. A lens window 13 and a fill light window 14 are arranged on the front shell 11. Furthermore, a lens glass 51 and a fill light glass 52 are arranged on the windows of the front shell for light to pass through. A sealing ring 15 is sandwiched between the front and rear shells to maintain a sealed environment in the cavity. The circuit control part of the whole machine is divided into a power board 40 and a main board 21.

[0060] Specifically, the power board 40 is close to the front shell 11 of the whole machine, and the fill light assembly 30 is arranged on the power board 40, so that the emission angle of the fill light assembly can be as large as possible. At the same time, the periphery of the fill light assembly is directly connected to the front shell 11, so that the metal material of the front shell 11 is used for heat conduction to dissipate heat during the operation of the fill light assembly. A via 41 is provided at the position corresponding to the lens window 13 of the power board 40, and similarly, a lens 22 is arranged at the corresponding position of the main board 21; this layout makes the space in the thickness direction of the whole machine compact enough, with high space utilization, making the whole machine more compact. The actual size of the whole machine is 60mm*60mm*30mm.

[0061] It can be seen from the above technical solutions that in this embodiment, the fill light assembly is integrated into the power board, which can save the space and thickness occupied by a board. Furthermore, the element that has the greatest impact on the thickness of the camera is the length of the lens assembly. Therefore, the camera of this embodiment integrates the power board with the fill light board, and further sets the power board between the lens assembly and the front shell. The space problem of the lens 22 is solved by opening a via on the power board, so that the power board and the main board form a nested relationship. Therefore, the thickness of the shell is determined by the distance between the main board 21 and the front surface of the front shell 11, so that the space in the thickness direction of the whole machine is sufficiently compact, the space utilization rate is high, and the whole machine is more compact.

[0062] The lens window 13 and the fill light window 14 may be arranged side by side in the horizontal direction, or arranged up and down in the vertical direction.

[0063] Combination Figure 4 and Figure 5 As shown, the camera of this embodiment further includes:

[0064] The light shielding pad 50 is disposed between the power board 40 and the front surface of the front shell 11 , and is isolated between the lens 22 and the fill light assembly 30 .

[0065] Wherein, the shading pad 50 comprises:

[0066] A fill light hole 501, the fill light hole 501 penetrates the light shielding pad 50 along the thickness direction;

[0067] A first light guiding surface 502 , which surrounds the fill light hole 501 and is radially arranged toward the fill light window 14 to guide the light of the fill light assembly 30 toward the fill light window 14 ;

[0068] A lens hole 503, which penetrates the light shielding pad 50 along the thickness direction; and

[0069] The second light guiding surface 504 surrounds the lens hole 503 and is radially arranged toward the lens window 13 .

[0070] The shading pad 50 is made of opaque material and is used to isolate between the fill light assembly 30 and the lens 22 to prevent the light of the fill light assembly 30 from directly entering the lens 22, thereby affecting the shooting of the lens assembly. The shading pad 50 guides the light through the hollowed-out position.

[0071] In a preferred embodiment, the combination Figure 2 As shown, the lens 22 is a telescopic lens, and the lens hole 503 and the through hole 41 together define a telescopic channel formed between the lens window 13 and the main board 21 .

[0072] This patented lens uses a VCM (voice coil motor) lens. VCM is a motor that can achieve a small range of axial movement of the lens through current control, thereby achieving automatic focusing.

[0073] In this embodiment, the light shielding pad 50 , the power board 40 , and the main board 21 form a space, and the lens 22 can move axially in the space, wherein the lens 22 passes through the through hole 41 on the power board 40 .

[0074] Preferably, the power board 40 is fixedly connected to the front shell 11 to form a heat dissipation path for the fill light assembly 30 .

[0075] Among them, such as 2 and Figure 5 As shown, the inner surface of the front shell 11 further includes an isolation rib 16 extending from between the lens window 13 and the fill light window 14 toward the inside of the shell, and the isolation rib 16 extends to cover the length direction or the width direction of the lens window 13 to form a light-proof isolation between the lens window 13 and the fill light window 14. Correspondingly, the front surface of the light-shielding pad 50 includes an isolation groove 505 for accommodating the isolation rib 16.

[0076] The setting of the isolation rib 16 and the isolation groove 505 can not only facilitate the installation and positioning of the light-shielding pad 50, but also form a light-proof isolation between the lens assembly 20 and the fill light assembly 30, which can prevent the light emitted by the fill light assembly 30 from directly entering the shooting range of the lens assembly 20 inside the outer shell, thereby preventing glare.

[0077] Furthermore, the rear surface of the light shielding pad 50 further includes a first annular rib and a second annular rib protruding from the rear surface, and the first annular rib and the second annular rib surround the lens hole 503 and the fill light hole 501 respectively.

[0078] The light shielding pad 50 can be formed of an elastic material with a certain elastic deformation, such as silicone. The thickness of the light shielding pad 50 can be slightly greater than the distance between the power board 40 and the front shell 11. When fixedly installed, the light shielding pad 50 is pressed between the power board 40 and the front shell 11, so that the front surface of the light shielding pad 50 can fit the lens window 13 and the fill light window 14, and the rear surface fits the power board 40 through the first annular rib and the second annular rib, thereby maximally preventing the light emitted by the fill light assembly 30 from directly entering the shooting range of the lens assembly 20 inside the housing to avoid light leakage. Preferably, the light shielding pad is formed in black.

[0079] like Figure 4 As shown, the camera of this embodiment further includes:

[0080] The lens glass 51 can cover the lens window 13 in a light-transmissive manner, and the lens glass 51 is formed as a polarized lens;

[0081] A fill light glass 52, the fill light glass 52 can cover the fill light window 14 in a light-transmissive manner, and the fill light glass 52 is formed as a polarized lens;

[0082] The polarization direction of the lens glass 51 is orthogonal to the polarization direction of the fill light glass 52 , so as to prevent the light of the fill light assembly 30 reflected by objects outside the housing from entering the housing through the lens window 13 .

[0083] Specifically, Figure 7 As shown, the inner surface of the lens glass 51 is pasted with a first polarizing film 511 , and the inner surface of the fill light glass 52 is pasted with a second polarizing film 521 .

[0084] Combination Figure 6 As shown, the outer surface of the lens glass 51 is fixed to the inner surface of the lens window 13 by adhesive, and a first exposure area 512 corresponding to the adhesive area S is formed between the outer edge of the first polarizing film 511 and the outer edge of the lens glass 51;

[0085] The outer surface of the fill light glass 52 is fixed to the inner surface of the fill light window 14 by adhesive, and a second exposure area 522 corresponding to the adhesive area is formed between the outer edge of the second polarizing film 521 and the outer edge of the fill light glass 52.

[0086] In this embodiment, a lens glass 51 and a fill light glass 52 are arranged on the front housing window, and polarizing films are attached to the two glass surfaces, which are located on the inner surface of the glass, and the polarizing directions of the polarizing films on the window glass 51 and the fill light glass 52 are orthogonal. Such an arrangement enables the light emitted by the fill light assembly 30 to be blocked by the first polarizing film 511 of the lens glass 51 after being reflected by an object located outside the housing, thereby reducing and eliminating the influence of reflections in the camera image.

[0087] Among them, combined Figure 6 As shown, the lens glass 51 and the fill light glass 52 are generally fixed to the front shell 11 by glue curing in the S area. The commonly used glue is UV glue, which can only be cured under ultraviolet light, and the polarizing film has a blocking effect on ultraviolet rays. Therefore, when the first polarizing film 511 is attached to the lens glass 51, the distance from the edge of the glass is a=1-2mm to form a blank area, that is, the corresponding first exposure area 512. In this way, when the lens glass 51 is placed on the front shell 11 and glued and cured, it can ensure that the glue is cured normally.

[0088] In a preferred embodiment, in order to facilitate the distinction of the polarization directions of the lens glass and the fill light glass, the lens glass and the fill light glass can be formed into an axially symmetrical pattern, but avoid forming a centrally symmetrical pattern. For example, they can be formed into a rectangular shape, but not a square shape or a circle.

[0089] like Figure 8 As shown, the housing further comprises:

[0090] a pair of first fixing points 61, which are symmetrically arranged on a pair of opposite side walls of the housing; and

[0091] A pair of second fixing points 62 are symmetrically disposed on a pair of opposite side walls of the housing and are coplanar with the pair of first fixing points 61 , respectively.

[0092] Among them, Fig. 9 and Fig.10 As shown, the housing is adjustably fixed to the first mounting bracket 100 via a first fixing point 61 and a second fixing point 62.

[0093] The pair of first fixing points 61 have a first degree of freedom of translation along an axial direction perpendicular to the lens 22 relative to the first mounting bracket 100 , and the pair of second fixing points 62 have a second degree of freedom of rotation around the first fixing points 61 relative to the first mounting bracket 100 .

[0094] like Figure 8 and Fig.11 As shown, the housing further comprises:

[0095] The third fixing point 63 is disposed on the rear surface of the rear housing 12 to be fixedly connected to the second mounting bracket 200 .

[0096] like Figure 8 As shown, threaded holes are provided on the back and sides of the whole machine for installing fixing brackets;

[0097] A typical support method is Fig. 9 As shown, the bracket is generally composed of a clamp, an adapter bracket and a U-shaped bracket; the clamp fixes the adapter bracket to the instrument, and then the U-shaped bracket is locked on the adapter bracket by screws, so that the whole machine can monitor the instrument data; the wires at the rear of the whole machine can also be fixed by the wire management buckle on the adapter bracket;

[0098] In addition, the whole machine can also be fixed on other planes through a U-shaped bracket. Feature 1 of the U-shaped bracket is used to fix with the plane and adjust; feature 2 is used to adjust the whole machine in the up and down direction; feature 3 is used for adjustment in the rotation direction;

[0099] In addition, the whole machine can also be installed with other brackets according to the actual scene, such as Fig.11 .

[0100] As can be seen from the above technical solution, in this embodiment, the fill light assembly is integrated into the power board, which can save the space and thickness occupied by a board. Furthermore, the element that has the greatest impact on the thickness of the camera is the length of the lens assembly. Therefore, the camera of this embodiment integrates the power board with the fill light board, and further sets the power board between the lens assembly and the front shell. The space problem of the lens 22 is solved by opening a via on the power board, so that the power board and the main board form a nested relationship. Therefore, the thickness of the shell is determined by the distance between the main board 21 and the front surface of the front shell 11, so that the space in the thickness direction of the whole machine is compact enough, the space utilization rate is high, and the whole machine is more compact.

[0101] Herein, “a” or “an” does not mean limiting the number of the relevant parts of the present invention to “only one”, and “a” or “an” does not mean excluding the situation where the number of the relevant parts of the present invention is “more than one”.

[0102] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0103] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention, such as combination, division or repetition of features, should be included in the scope of protection of the present invention.
