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

[0119] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0120] In order to solve the problems in the prior art, the present invention provides a camera for reducing interference from flying insects, wherein a lens assembly and a fill light assembly are arranged in a horizontal direction, and in the direction of the optical axis, the lens assembly is located at the front end of the fill light assembly, thereby reducing the flying insects attracted by the fill light assembly from appearing within the field of view of the lens assembly.

[0121] like Figures 1 to 3 As shown, one embodiment of the present invention provides a camera for reducing the interference of flying insects, comprising:

[0122] The fuselage 10 is formed as a cuboid with a cavity inside, and an opening 11 is formed at the front end in the length direction, and the opening 11 is formed in a rectangular shape with a width greater than a height, wherein the length direction and the width direction of the opening 11 both extend in the horizontal direction, and the edge of the opening 11 forms a rectangular fixed end surface;

[0123] A front cover 20, the front cover 20 is mounted on a fixed end surface of the opening 11 via a first fastener 21 to close the cavity, wherein the first fastener 21 is connected to four end corners of the opening 11 and the middle of a pair of long sides extending along the width direction;

[0124] The lens assembly 30 is mounted on the front cover 20 from the inside via the first fixing sheet metal 71 so as to be located in the cavity. The optical axis direction of the lens assembly 30 is consistent with the length direction and faces the front of the front cover 20. The lens assembly 30 is surrounded by the first fixing sheet metal 71.

[0125] A fill light assembly 40, the fill light assembly 40 is installed on the front cover 20 from the inside to be located in the cavity, the light emitting direction of the fill light assembly 40 is consistent with the length direction, and the fill light assembly 40 has a light emitting surface 43 that is flush with the front cover 20 or protrudes from the front cover 20, so as to provide an auxiliary light source toward the field of view of the lens assembly 30 through the light emitting surface 43;

[0126] The mainboard assembly 33 is installed on the front cover 20 from the inside via the second fixing sheet metal 72 so as to be located in the cavity. The second fixing sheet metal is sleeved on the outside of the first fixing sheet metal 71. The mainboard assembly 33 is fixed to the outer surface of the second fixing sheet metal 72 so that the mainboard assembly 33 is located directly behind the lens assembly 30 in the length direction.

[0127] The lens assembly 30 and the fill light assembly 40 are arranged on the front cover 20 along the horizontal direction, wherein a pair of first fasteners 21 connected to the middle of a pair of long sides extending along the width direction are located between the lens assembly 30 and the fill light assembly 40 .

[0128] In a specific example, the first fixed sheet metal 71 includes a first fixed plate 711 and a pair of first fixed arms 712 connected to a pair of opposite first sides of the first fixed plate 711, the first fixed arms 712 extend along the length direction, and the front ends of the first fixed arms 712 are connected to the inner surface of the front cover 20;

[0129] The second fixed sheet metal 72 includes a second fixed plate 721 and a pair of second fixed arms 722 connected to a pair of opposite second sides of the second fixed plate 721, the second fixed arms 722 extend along the length direction, the front end of the second fixed arms 722 is connected to the front cover 20, the second side is perpendicular to the first side, the length of the second fixed arm 722 is greater than the length of the first fixed arm 712, and the length of the second side is greater than or equal to the length of the first side;

[0130] The lens assembly 30 is installed in a space enclosed by the first fixing arm 712 , the second fixing arm 722 , and the first fixing plate 711 .

[0131] like Figure 1 As shown, the first fixed sheet metal 71 and the second fixed sheet metal 72 both form a U-shaped bracket structure, and the first fixed sheet metal 71 and the second fixed sheet metal 72 are arranged at an angle difference of 90°, and the first fixed plate 711 and the second fixed plate 721 are coaxially arranged in parallel, so that the first fixed sheet metal 71 and the second fixed sheet metal 72 can be combined to form a hollow rectangular parallelepiped, wherein the lens assembly 30 is located inside the rectangular parallelepiped, and the mainboard assembly 33 is located on the outer surface of the rectangular parallelepiped, so that the lens assembly 30 and the mainboard assembly 33 can be compactly arranged in the cavity of the fuselage 10.

[0132] Since the lens assembly 30, the fill light assembly 40, and the main board assembly 33 all need to be installed on the front cover 20, the coaxial alignment fixing method of the lens assembly 30 and the main board assembly 33 can reduce the size of the front cover 20, that is, the front cover 20 only needs to meet the installation width required by the lens assembly 30 and the fill light assembly 40, and there is no need to set the installation space required for the lens assembly 30, the fill light assembly 40, and the main board assembly 33 in parallel, which has a significant effect on reducing the size of the fuselage.

[0133] Furthermore, the lens assembly 30, the fill light assembly 40 and the mainboard assembly 33 must be connected by signal cables. If the three components are arranged side by side, the complexity of the wiring layout inside the fuselage will inevitably increase significantly. However, the coaxial alignment of the lens assembly 30 and the mainboard assembly 33 can at least reduce the influence of the cable layout on the complexity of the internal layout of the fuselage by shortening the distance between the lens assembly 30 and the mainboard assembly 33.

[0134] In a preferred example, the lens assembly 30 and the mainboard assembly 33 are connected in a direct plug-in manner without the need for an adapter plate. Specifically, the lens assembly 30 and the mainboard assembly 33 are connected in a manner of matching a connection terminal with a connection socket, and the cables connected between the connection terminal and the connection socket can be in the form of, for example, a flat cable or a flexible printed circuit, so that the cables can be arranged in bundles without being dispersed, thereby reducing the complexity of cable connection and layout. The corresponding connection terminals and connection sockets are coaxially arranged along an axial direction parallel to the length direction.

[0135] In a preferred example, the lens assembly 30 may include a lens main board, which may be arranged on the outer surface of the first fixed plate 711, that is, located in the gap between the first fixed sheet metal 71 and the second fixed sheet metal 72. The direct plug-in connection between the lens assembly 30 and the main board assembly 33 can be achieved through the partial hollow design of the second fixed plate 721, so as to further eliminate the use of connecting cables.

[0136] Specifically, the second fixing sheet metal 72 is sleeved on the outside of the first fixing sheet metal 71, and the size of each part of the second fixing sheet metal 72 should be slightly larger than the size of the corresponding part of the first fixing sheet metal 71. For example, the length of the second fixing arm 722 is larger than the length of the first fixing arm 712, and the length of the second side is greater than or equal to the length of the first side.

[0137] The rectangular parallelepiped structure formed by the pair of first fixing arms 712 , the pair of second fixing arms 722 , and the first fixing plate 711 can further provide protection for the lens assembly 30 .

[0138] Normally, the fill light assembly is mostly arranged above the lens assembly, and due to the size of the fuselage, the fill light assembly is adjacent to the lens assembly or the distance between them is very small. Therefore, when the fill light assembly is turned on, the flying insects attracted by it can easily enter the field of view of the lens assembly, and the spiders attracted by the flying insects will often appear in the field of view of the lens assembly due to their biological characteristics and the influence of gravity, and even weave webs in front of the window of the lens assembly, thereby seriously affecting the shooting effect and picture quality of the lens assembly.

[0139] In this embodiment, combined with Figure 2a and Figure 2bAs shown, a fuselage shape with a width greater than a height is provided, so that the lens assembly 30 and the fill light assembly 40 are placed side by side in the horizontal direction. In this embodiment, the length direction of the fuselage 10 is defined as being consistent with the optical axis direction L of the lens assembly 30, wherein the side photographed by the lens assembly 30 is defined as the front side of the optical axis direction L. The fuselage 10 has a cavity inside and an opening 11 on the front side, wherein the shape of the opening 11 is the same as the cross-sectional shape of the fuselage 10, and optionally, the size of the opening 11 may be different from or the same as the cross-sectional size of the fuselage 10. The width direction of the opening 11 extends in the horizontal direction, and the height direction extends in the vertical direction. The optical axis direction L also extends in the horizontal plane.

[0140] In this embodiment, the width of the opening 11 can be significantly greater than the height, for example, twice the height, so that the lens assembly 30 and the fill light assembly 40 are placed side by side in the horizontal direction. Thus, the possibility of flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 due to the influence of gravity can be eliminated.

[0141] The front cover 20 has a window 31 protruding from the front surface of the front cover 20 , and the lens assembly 30 shoots through the window 31 . The window 31 is formed in a rectangular shape, and a pair of second through holes 311 are formed at the lower edge of the window 31 .

[0142] The camera for reducing the interference of flying insects includes a light shield 50, which is installed on the front cover 20 from the outside and surrounds the viewing window 31. The light shield 50 is connected to the front cover 20 through a buckle structure, wherein the buckle structure includes:

[0143] A pair of first clamping portions 811, the pair of first clamping portions 811 protrude from the front cover 20 along the length direction from the upper edge of the viewing window 31;

[0144] A pair of second clamping portions 812 extending from the lower edge of the opening 11 along the length direction to protrude from the front cover 20 through the second through hole 311;

[0145] A pair of first buckle portions 813 , the pair of first buckle portions 813 are mounted on the inner wall of the light shield 50 to be engaged with the pair of first engaging portions 811 ;

[0146] A pair of second slots 814 are formed through the lower edge of the light shield 50 , and a pair of second engaging portions 812 are engaged with the pair of second slots 814 .

[0147] In this embodiment, the front cover 20 can be firmly fixed to the body 10 by the first fastener 21, and the light shield 50 can only be fixed to the front cover 20. In order to improve the mosquito-proof effect, in a preferred example, the surface of the light shield 50 has a Teflon coating.

[0148] Teflon generally refers to polytetrafluoroethylene (PTFE), commonly known as the "king of plastics". It is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It has excellent heat and cold resistance and can be used for a long time at -180 to 260°C. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and its friction coefficient is extremely low, so it can be used as a lubricant and has also become an ideal coating for the inner layer of easy-to-clean water pipes.

[0149] By utilizing the low friction coefficient characteristic of Teflon, the surface of the light shield 50 is made unfavorable for flying insects or spiders to stay. Combined with the structural characteristics of the light shield 50 and the positional relationship between the fill light assembly and the lens assembly, the camera for reducing interference from flying insects in this embodiment can minimize the appearance of flying insects attracted by the fill light assembly within the field of view of the lens assembly, thereby improving the picture shooting quality of the camera.

[0150] Based on the characteristics of Teflon coating, the light shield 50 and the front cover 20 are both made of metal materials. Metal materials have high rigidity and cannot be conveniently provided with a snap-on connection structure. Therefore, in the fixing structure for the light shield 50 in this embodiment, a snap-on structure consisting of a plastic structure and a metal structure is used to achieve connection.

[0151] Specifically, the shading hood 50 and the front cover 20 are both made of metal materials, and the body 10 is formed of a plastic material with elastic deformation. Therefore, in this embodiment, the first clamping portion 811 is integrally formed with the front cover 20 and is formed of a metal material, and the second clamping portion 812 is integrally formed with the body 10 and is formed of a plastic material. The first buckle portion 813 is formed as a plastic part fixedly connected to the inner wall of the shading hood 50 via a second fastener, and the second clamping groove 814 is directly opened at the lower edge of the shading hood 50 and is formed of a metal material.

[0152] In the snap-fit ​​structure of the sunshade 50, in the snap-fitting first snap-fitting portion 811 and the first snap-fitting portion 813, the first snap-fitting portion 811 is made of metal, and the first snap-fitting portion 813 is made of plastic; in the snap-fitting second snap-fitting portion 812 and the second snap-fitting groove 814, the second snap-fitting portion 812 is made of plastic, and the second snap-fitting groove 814 is made of metal.

[0153] The second slot 814 can also be used as a drainage hole.

[0154] Furthermore, if Figure 1 and Figure 4a , Figure 4b As shown, the camera for reducing interference from flying insects in this embodiment also includes:

[0155] The light shield 50 is installed on the front cover 20 from the outside and surrounds the viewing window 31, wherein the light shield 50 includes:

[0156] A top wall 51, the top wall 51 protrudes from the viewing window 31 from above the viewing window 31;

[0157] A first side wall 52 and a second side wall 53, the first side wall 52 and the second side wall 53 protrude from the window 31 from both sides in the width direction of the window 31, wherein the first side wall 52 is isolated between the window 31 and the light exit surface 43;

[0158] A circular chamfer is formed between the top wall 51 and the first side wall 52 and the second side wall 53 , and a circular chamfer is formed between the top wall 51 , the first side wall 52 , the second side wall 53 and the edge of the window 31 .

[0159] The functions of the sunshade 50 are divided into two types. One is to prevent excessive light from causing glare within the field of view of the lens assembly under sufficient light conditions, especially using the top wall 51 to block the sunlight from above the lens assembly 30; the other is to use the first side wall 52 and the second side wall 53, especially the first side wall 52, to block the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 when the fill light assembly is turned on, thereby preventing flying insects attracted by the fill light assembly from flying around the window 31.

[0160] In order to further prevent flying insects or spiders from staying near the lens assembly 30, the surface of the lens hood 50 is formed into a smooth surface, and arc chamfers are used between each surface to avoid forming sharp corners or steps, thereby preventing flying insects or spiders from staying on the surface of the lens hood 50.

[0161] In a preferred example, Figure 3 As shown, in the optical axis direction L, the window 31 of the lens assembly 30 is located in front of the light exit surface 43 of the fill light assembly 40, and the flying insects attracted by the fill light assembly 40 are concentrated near the light exit surface 43. Due to the limitation of the field of view angle of the lens assembly 30, the possibility of the flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 can be minimized. In addition, the light source is at the rear side of the lens assembly 30, and there is no light source within a certain range in front of the lens assembly 30, which will not attract flying insects. Therefore, the number of flying insects in front of the lens assembly 30 is greatly reduced.

[0162] like Figure 4a As shown, in the optical axis direction L, the length of the top end of the first side wall 52 and the length of the bottom end of the second side wall 53 are greater than the length of the bottom end;

[0163] The front end of the top wall 51 , the front end of the first side wall 52 , and the front end of the second side wall 53 together form a downwardly inclined light shielding surface that forms an acute angle with the vertical direction.

[0164] like Figure 5 As shown, in order to prevent the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 , the light emission angle of the fill light assembly 40 avoids the first side wall 52 .

[0165] The field of view of the lens module is the same as that of the fill light module. When the fill light module is located behind the lens module, ensure that the field of view of the fill light module does not interfere with the decorative parts on the front side of the lens module. The fill light retreat distance depends on the field of view of the lens. The greater the difference between the lens and the fill light, the better the effect.

[0166] like Figure 1 As shown, the fill light assembly 40 includes a light board main board 41, a plurality of fill lights 42a mounted on the light board 42, and a light emitting surface 43 protruding from the front cover 20;

[0167] The light emitting surface 43 forms a second accommodating cavity on the inner surface of the front cover 20, and the lamp board 42 is installed in the second accommodating cavity;

[0168] The light board main board 41 is installed on the inner surface of the front cover 20 to cover the second accommodating cavity. The light board 42 is fixed to the light board main board 41 via a third fastener. The light board 42 is arranged parallel to the light board main board 41.

[0169] The light board main board 41 includes a light board cable 44 connected between the light board main board 41 and the main board assembly 33, and a light shielding terminal 45 sleeved on the light board cable 44;

[0170] The connection between the light board cable 44 and the light board main board 41 is adjacent to a side edge of the light board main board 41 , and a wire outlet gap for the light board cable 44 is formed between the side edge and the inner surface of the front cover 20 , and the light shielding terminal 45 is filled in the wire outlet gap.

[0171] The light shielding terminal 45 includes:

[0172] The light shielding body 451 is formed in a rectangular parallelepiped shape, and its two ends are respectively against the light board main board 41 and the light board 42;

[0173] The outlet terminal 452 is formed on the light shielding body 451 and has an outlet hole penetrating the light shielding body 451. The light board cable 44 is passed through the outlet hole. The outlet terminal 452 has an inlet end 4521 and an outlet end 4522 located on both sides of the light shielding body 451. The outlet terminal 452 is formed in a shape that gradually shrinks from the inlet end 4521 to the outlet end 4522.

[0174] The wire outlet end 4522 is located at a side away from the second accommodating cavity, and the wire outlet end 4522 wraps the light board cable 44 .

[0175] In this embodiment, the light emitting surface 43 protrudes from the front cover 20 to form a second accommodating cavity for accommodating the light board 42 and the fill light 42a on one side of the inner surface of the front cover 20. When the light board main board 41 is installed on the front cover 20, the light board main board 41 is flush with the inner surface of the front cover 20, and at the same time, the light board 42 and the fill light 42a are accommodated in the second accommodating cavity. The setting of the second accommodating cavity can effectively reduce the exposure of the light of the fill light 42a to the inside of the fuselage 10. However, inevitably, the light board cable 44 connected to the light board main board 41 must pass through the side of the light board main board 41 facing the second accommodating cavity to the outside of the second accommodating cavity. In this embodiment, a light shielding terminal 45 is provided to shield the outlet gap.

[0176] The light shielding terminal 45 adopts a rectangular light shielding body 451 to fill the outlet gap between the light board main board 41 and the front cover 20, one end of which is against the light board main board 41, and the other side is against the light board 42. And the light shielding terminal 45 is sleeved and wrapped with the light board cable 44 through the outlet terminal 452 with an outlet hole. Among them, the outlet terminal 452 is formed into a trumpet shape that gradually shrinks from the input end 4521 to the outlet end 4522. The larger input end 4521 is used to wrap the connection terminal of the light board cable 44, and the smaller outlet end 4522 is used to wrap the outlet cable of the light board cable 44. Among them, the outlet end 4522 can be formed in the form of an elastic body to further reduce the possibility of light leakage.

[0177] The plurality of fill lights 42a are arranged in a matrix and formed into a rectangular shape with a width greater than a height.

[0178] In a preferred example, the supplementary light 42a is an insect repellent light.

[0179] Insect repellent lamp, also known as insect-proof lamp, anti-ultraviolet fluorescent lamp, yellow light lamp. The lamp emits yellow light above 450nm, which does not stimulate the flight of insects or utilizes the light adaptation of their eyes to prevent insects from gathering in illuminated places or inhibit their nighttime activities.

[0180] Among them, the light board 42 has three light board fixing studs 421 extending toward the light board main board 41, one pair of the light board fixing studs 421 are formed as positioning studs for the light board main board 41, and another light board fixing stud 421 is formed as a connecting stud for the light board main board 41, and a pair of light board fixing studs 421 are respectively adjacent to a pair of opposite edges of the main board 42.

[0181] The lamp board main board 41 has a pair of positioning screw holes 41 a for the positioning studs to pass through, and a connecting screw hole 41 b for connecting the studs to the third fastener.

[0182] The third fastener connected to the positioning screw hole 41 a should include a gasket to prevent light from leaking from the positioning screw hole 41 a.

[0183] Furthermore, the four end corners of the light board main board 41 are fixedly connected to the inner surface of the front cover 20 by fourth fasteners;

[0184] The inner surface of the front cover 20 includes a pair of lamp board mainboard positioning posts 22 protruding toward the lamp board mainboard 41 , and the lamp board mainboard positioning posts 22 are respectively adjacent to a pair of non-adjacent end corners of the lamp board mainboard 41 .

[0185] like Figure 3 As shown, in the width direction of the opening 11 , a mounting gap is formed between the window 31 and the light emitting surface 43 . The mounting gap is formed on the front surface of the front cover 20 . Therefore, the mounting gap is located at the rear side of the window 31 in the optical axis direction L.

[0186] like Figure 6a and Figure 6b As shown, the camera for reducing interference from flying insects in this embodiment also includes:

[0187] The decorative cover 60 is installed on the front cover 20 from the outside and surrounds the light emitting surface 43. The decorative cover 60 has a first edge 61 connected to the first side wall 52. The first edge 61 and the first side wall 52 form a smooth surface for shielding the installation space.

[0188] contrast Figure 3 and Figure 6b It can be seen that an installation gap is formed between the window 31 and the light emitting surface 43, and the decorative cover 60 and the light shield 50 are seamlessly connected, so that there is no protrusion or groove on the appearance of the camera, thereby reducing spiders from using edges to build webs.

[0189] The front cover 20 has four third slots 23 penetrating the front cover 20 , and the third slots 23 correspond to the end angle positions of the light emitting surface 43 ;

[0190] The inner surface of the decorative cover 60 has a third clamping portion 62 that is clamped with the third clamping groove 23 . The decorative cover 60 is formed of a plastic material with elastic deformation, and the third clamping portion 62 is integrally formed with the decorative cover 60 .

[0191] The decorative cover 60 can be positioned with the front cover 20 via positioning posts 63 protruding from the inner surface thereof, wherein positions of the positioning posts 63 correspond to a pair of non-adjacent end corner edges of the light emitting surface 43 .

[0192] like Figure 7 As shown, the lens assembly 30 includes:

[0193] A window glass 32 , the window glass 32 covers the window 31 from the inner side of the window 31 , wherein the window glass 32 includes a transparent portion 321 filled into the window 31 , and a fixing portion 322 extending outward from the periphery of the transparent portion 321 ;

[0194] The front end surface of the transparent portion 321 is flush with the outer surface of the window 31 , and the fixing portion 322 is formed on the rear end surface of the transparent portion 321 to form a step with the transparent portion 321 that fits the inner surface of the front cover 20 .

[0195] The window glass in this embodiment adopts the shape of step glass, and combined with the installation of the light shield 50, there is no protrusion or groove on the appearance of the camera, thereby reducing the use of edges by spiders to build webs.

[0196] In this embodiment, the lens assembly 30 and the fill light assembly 40 are placed side by side in the horizontal direction, thereby eliminating the possibility that flying insects and spiders attracted by the fill light assembly enter the field of view of the lens assembly 30 due to the influence of gravity.

[0197] Furthermore, in the optical axis direction L, the window 31 of the lens assembly 30 is located in front of the light exit surface 43 of the fill light assembly 40, and the flying insects attracted by the fill light assembly 40 are concentrated near the light exit surface 43. Due to the limitation of the field of view angle of the lens assembly 30, the possibility of the flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 can be minimized. In addition, the light source is at the rear side of the lens assembly 30, and there is no light source within a certain range in front of the lens assembly 30, which will not attract flying insects. Therefore, the number of flying insects in front of the lens assembly 30 is greatly reduced.

[0198] The functions of the sunshade 50 are divided into two types. One is to prevent excessive light from causing glare within the field of view of the lens assembly under sufficient light conditions, especially using the top wall 51 to block the sunlight from above the lens assembly 30; the other is to use the first side wall 52 and the second side wall 53, especially the first side wall 52, to block the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 when the fill light assembly is turned on, thereby preventing flying insects attracted by the fill light assembly from flying around the window 31.

[0199] By utilizing the low friction coefficient characteristic of Teflon, the surface of the light shield 50 is made unfavorable for flying insects or spiders to stay. Combined with the structural characteristics of the light shield 50 and the positional relationship between the fill light assembly and the lens assembly, the camera of this embodiment can minimize the appearance of flying insects attracted by the fill light assembly within the field of view of the lens assembly, thereby improving the picture shooting quality of the camera.

[0200] like Figures 1 to 3 As shown, one embodiment of the present invention provides a camera for reducing the interference of flying insects, comprising:

[0201] a fuselage 10, the fuselage 10 forming an internal cavity;

[0202] A front cover 20, the front cover 20 is mounted on the body 10 to seal the cavity;

[0203] The lens assembly 30 is located in the cavity, and the lens assembly 30 has a window 31 protruding from the front cover 20, so as to shoot through the window 31;

[0204] A fill light assembly 40, the fill light assembly 40 is located in the cavity, and the fill light assembly 40 has a light emitting surface 43, so as to provide an auxiliary light source toward the field of view of the lens assembly 30 via the light emitting surface 43;

[0205] The lens assembly 30 and the fill light assembly 40 are arranged on the front cover 20 along the horizontal direction, and in the optical axis direction, the window 31 of the lens assembly 30 is located in front of the light emitting surface 43 of the fill light assembly 40 .

[0206] Normally, the fill light assembly is mostly arranged above the lens assembly, and due to the size of the fuselage, the fill light assembly is adjacent to the lens assembly or the distance between them is very small. Therefore, when the fill light assembly is turned on, the flying insects attracted by it can easily enter the field of view of the lens assembly, and the spiders attracted by the flying insects will often appear in the field of view of the lens assembly due to their biological characteristics and the influence of gravity, and even weave webs in front of the window of the lens assembly, thereby seriously affecting the shooting effect and picture quality of the lens assembly.

[0207] In this embodiment, combined with Figure 2a and Figure 2b As shown, the lens assembly 30 and the fill light assembly 40 are placed side by side in the horizontal direction. Thus, the possibility that flying insects and spiders attracted by the fill light assembly enter the field of view of the lens assembly 30 due to the influence of gravity can be eliminated.

[0208] Furthermore, if Figure 3 As shown, in the optical axis direction L, the window 31 of the lens assembly 30 is located in front of the light exit surface 43 of the fill light assembly 40, and the flying insects attracted by the fill light assembly 40 are concentrated near the light exit surface 43. Due to the limitation of the field of view angle of the lens assembly 30, the possibility of the flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 can be minimized. In addition, the light source is at the rear side of the lens assembly 30, and there is no light source within a certain range in front of the lens assembly 30, which will not attract flying insects. Therefore, the number of flying insects in front of the lens assembly 30 is greatly reduced.

[0209] Specifically, Figure 1 As shown, the lens assembly 30 and the fill light assembly 40 are independently and separately arranged in the horizontal direction, and the window 31 and the light emitting surface 43 are independently and separately arranged in the horizontal direction.

[0210] The lens assembly 30 and the fill light assembly 40 are spaced apart to form independent assemblies. Further, on the front cover 20, the window 31 and the light emitting surface 43 are also spaced apart to form an installation interval between the window 31 and the light emitting surface 43.

[0211] In a preferred example, the camera for reducing interference from flying insects of this embodiment includes a hood 50, which is installed on the front cover 20 from the outside and surrounds the window 31. In the direction of the optical axis, the front end surface of the hood 50 exceeds the light emitting surface 43.

[0212] The front end surface of the sunshade 50 is formed as a shading surface, wherein in the optical axis direction, the shading surface of the sunshade 50 is located in front of the light emitting surface 43 of the fill light assembly to prevent the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30.

[0213] In a preferred example, the surface of the light shield 50 has a Teflon coating, and the light shield 50 includes a top wall 51 protruding from the viewing window 31 from above the viewing window 31 .

[0214] Teflon generally refers to polytetrafluoroethylene (PTFE), commonly known as the "king of plastics". It is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It has excellent heat and cold resistance and can be used for a long time at -180 to 260°C. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and its friction coefficient is extremely low, so it can be used as a lubricant and has also become an ideal coating for the inner layer of easy-to-clean water pipes.

[0215] By utilizing the low friction coefficient characteristic of Teflon, the surface of the light shield 50 is made unfavorable for flying insects or spiders to stay. Combined with the structural characteristics of the light shield 50 and the positional relationship between the fill light assembly and the lens assembly, the camera of this embodiment can minimize the appearance of flying insects attracted by the fill light assembly within the field of view of the lens assembly, thereby improving the picture shooting quality of the camera.

[0216] The functions of the sunshade 50 are divided into two types. One is to prevent excessive light from causing glare within the field of view of the lens assembly under sufficient light conditions, especially using the top wall 51 to block the sunlight from above the lens assembly 30; the other is to block the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 when the fill light assembly is turned on, thereby preventing flying insects attracted by the fill light assembly from flying around the window 31.

[0217] Specifically, the light shield 50 includes:

[0218] A top wall 51, the top wall 51 protrudes from the viewing window 31 from above the viewing window 31;

[0219] A first side wall 52 and a second side wall 53, the first side wall 52 and the second side wall 53 protrude from the window 31 from both sides in the width direction of the window 31, wherein the first side wall 52 is isolated between the window 31 and the light exit surface 43;

[0220] A circular chamfer is formed between the top wall 51 and the first side wall 52 and the second side wall 53 , and a circular chamfer is formed between the top wall 51 , the first side wall 52 , the second side wall 53 and the edge of the window 31 .

[0221] When the fill light assembly is turned on, the light shield 50 uses the first side wall 52 and the second side wall 53, especially the first side wall 52, to shield the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30, thereby preventing flying insects attracted by the fill light assembly from flying around the window 31.

[0222] like Figures 1 to 3 As shown, one embodiment of the present invention provides a camera for reducing the interference of flying insects, comprising:

[0223] The fuselage 10 is formed as a rectangular parallelepiped with a cavity inside, and an opening 11 is formed at the front end in the length direction, and the opening 11 is formed in a rectangular shape with a width greater than a height, wherein the length direction and the width direction of the opening 11 both extend in a horizontal plane;

[0224] A front cover 20, the front cover 20 is mounted on the opening 11 to close the cavity;

[0225] The lens assembly 30 is installed on the front cover 20 from the inside to be located in the cavity. The optical axis direction of the lens assembly 30 is consistent with the length direction and faces the front of the front cover 20. The lens assembly 30 has a window 31 protruding from the front cover 20 for shooting through the window 31;

[0226] A fill light assembly 40, the fill light assembly 40 is installed on the front cover 20 from the inside to be located in the cavity, the light emitting direction of the fill light assembly 40 is consistent with the length direction, and the fill light assembly 40 has a light emitting surface 43 that is flush with the front cover 20 or protrudes from the front cover 20, so as to provide an auxiliary light source toward the field of view of the lens assembly 30 through the light emitting surface 43;

[0227] The lens assembly 30 and the fill light assembly 40 are arranged on the front cover 20 along the horizontal direction, and in the optical axis direction, the window 31 of the lens assembly 30 is located in front of the light emitting surface 43 of the fill light assembly 40 .

[0228] Normally, the fill light assembly is mostly arranged above the lens assembly, and due to the size of the fuselage, the fill light assembly is adjacent to the lens assembly or the distance between them is very small. Therefore, when the fill light assembly is turned on, the flying insects attracted by it can easily enter the field of view of the lens assembly, and the spiders attracted by the flying insects will often appear in the field of view of the lens assembly due to their biological characteristics and the influence of gravity, and even weave webs in front of the window of the lens assembly, thereby seriously affecting the shooting effect and picture quality of the lens assembly.

[0229] In this embodiment, combined with Figure 2a and Figure 2b As shown, a fuselage shape with a width greater than a height is provided, so that the lens assembly 30 and the fill light assembly 40 are placed side by side in the horizontal direction. In this embodiment, the length direction of the fuselage 10 is defined as being consistent with the optical axis direction L of the lens assembly 30, wherein the side photographed by the lens assembly 30 is defined as the front side of the optical axis direction L. The fuselage 10 has a cavity inside and an opening 11 on the front side, wherein the shape of the opening 11 is the same as the cross-sectional shape of the fuselage 10, and optionally, the size of the opening 11 may be different from or the same as the cross-sectional size of the fuselage 10. The width direction of the opening 11 extends in the horizontal direction, and the height direction extends in the vertical direction. The optical axis direction L also extends in the horizontal plane.

[0230] In this embodiment, the width of the opening 11 can be significantly greater than the height, for example, twice the height, so that the lens assembly 30 and the fill light assembly 40 are placed side by side in the horizontal direction. Thus, the possibility of flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 due to the influence of gravity can be eliminated.

[0231] Furthermore, if Figure 3 As shown, in the optical axis direction L, the window 31 of the lens assembly 30 is located in front of the light exit surface 43 of the fill light assembly 40, and the flying insects attracted by the fill light assembly 40 are concentrated near the light exit surface 43. Due to the limitation of the field of view angle of the lens assembly 30, the possibility of the flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 can be minimized. In addition, the light source is at the rear side of the lens assembly 30, and there is no light source within a certain range in front of the lens assembly 30, which will not attract flying insects. Therefore, the number of flying insects in front of the lens assembly 30 is greatly reduced.

[0232] Furthermore, if Figure 1 and Figure 4a , Figure 4b As shown, the camera for reducing interference from flying insects in this embodiment also includes:

[0233] The light shield 50 is installed on the front cover 20 from the outside and surrounds the viewing window 31, wherein the light shield 50 includes:

[0234] A top wall 51, the top wall 51 protrudes from the viewing window 31 from above the viewing window 31;

[0235] A first side wall 52 and a second side wall 53, the first side wall 52 and the second side wall 53 protrude from the window 31 from both sides in the width direction of the window 31, wherein the first side wall 52 is isolated between the window 31 and the light exit surface 43;

[0236] A circular chamfer is formed between the top wall 51 and the first side wall 52 and the second side wall 53 , and a circular chamfer is formed between the top wall 51 , the first side wall 52 , the second side wall 53 and the edge of the window 31 .

[0237] The functions of the sunshade 50 are divided into two types. One is to prevent excessive light from causing glare within the field of view of the lens assembly under sufficient light conditions, especially using the top wall 51 to block the sunlight from above the lens assembly 30; the other is to use the first side wall 52 and the second side wall 53, especially the first side wall 52, to block the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 when the fill light assembly is turned on, thereby preventing flying insects attracted by the fill light assembly from flying around the window 31.

[0238] In order to further prevent flying insects or spiders from staying near the lens assembly 30, the surface of the lens hood 50 is formed into a smooth surface, and arc chamfers are used between each surface to avoid forming sharp corners or steps, thereby preventing flying insects or spiders from staying on the surface of the lens hood 50.

[0239] Furthermore, the surface of the light shield 50 has a Teflon coating.

[0240] Teflon generally refers to polytetrafluoroethylene (PTFE), commonly known as the "king of plastics". It is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It has excellent heat and cold resistance and can be used for a long time at -180 to 260°C. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and its friction coefficient is extremely low, so it can be used as a lubricant and has also become an ideal coating for the inner layer of easy-to-clean water pipes.

[0241] By utilizing the low friction coefficient characteristic of Teflon, the surface of the light shield 50 is made unfavorable for flying insects or spiders to stay. Combined with the structural characteristics of the light shield 50 and the positional relationship between the fill light assembly and the lens assembly, the camera of this embodiment can minimize the appearance of flying insects attracted by the fill light assembly within the field of view of the lens assembly, thereby improving the picture shooting quality of the camera.

[0242] like Figure 4a As shown, in the optical axis direction L, the length of the top end of the first side wall 52 and the length of the bottom end of the second side wall 53 are greater than the length of the bottom end;

[0243] The front end of the top wall 51 , the front end of the first side wall 52 , and the front end of the second side wall 53 together form a downwardly inclined light shielding surface that forms an acute angle with the vertical direction.

[0244] like Figure 5 As shown, in order to prevent the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 , the light emission angle of the fill light assembly 40 avoids the first side wall 52 .

[0245] The field of view of the lens module is the same as that of the fill light module. When the fill light module is located behind the lens module, ensure that the field of view of the fill light module does not interfere with the decorative parts on the front side of the lens module. The fill light retreat distance depends on the field of view of the lens. The greater the difference between the lens and the fill light, the better the effect.

[0246] like Figure 1 As shown, the fill light assembly 40 includes a light board 41 and a plurality of fill lights 42 mounted on the light board 41.

[0247] The plurality of fill lights 42 are arranged in a matrix and are formed into a rectangular shape with a width greater than a height.

[0248] In a preferred example, the supplementary light 42 is an insect repellent light.

[0249] Insect repellent lamp, also known as insect-proof lamp, anti-ultraviolet fluorescent lamp, yellow light lamp. The lamp emits yellow light above 450nm, which does not stimulate the flight of insects or utilizes the light adaptation of their eyes to prevent insects from gathering in illuminated places or inhibit their nighttime activities.

[0250] like Figure 3 As shown, in the width direction of the opening 11 , a mounting gap is formed between the window 31 and the light emitting surface 43 . The mounting gap is formed on the front surface of the front cover 20 . Therefore, the mounting gap is located at the rear side of the window 31 in the optical axis direction L.

[0251] like Figure 6a and Figure 6b As shown, including:

[0252] The decorative cover 60 is installed on the front cover 20 from the outside and surrounds the light emitting surface 43. The decorative cover 60 has a first edge 61 connected to the first side wall 52. The first edge 61 and the first side wall 52 form a smooth surface for shielding the installation space.

[0253] contrast Figure 3 and Figure 6bIt can be seen that an installation gap is formed between the window 31 and the light emitting surface 43, and the decorative cover 60 and the light shield 50 are seamlessly connected, so that there is no protrusion or groove on the appearance of the camera, thereby reducing spiders from using edges to build webs.

[0254] like Figure 7 As shown, the lens assembly 30 includes:

[0255] A window glass 32 , the window glass 32 covers the window 31 from the inner side of the window 31 , wherein the window glass 32 includes a transparent portion 321 filled into the window 31 , and a fixing portion 322 extending outward from the periphery of the transparent portion 321 ;

[0256] The front end surface of the transparent portion 321 is flush with the outer surface of the window 31 , and the fixing portion 322 is formed on the rear end surface of the transparent portion 321 to form a step with the transparent portion 321 that fits the inner surface of the front cover 20 .

[0257] The window glass in this embodiment adopts the shape of step glass, and combined with the installation of the light shield 50, there is no protrusion or groove on the appearance of the camera, thereby reducing the use of edges by spiders to build webs.

[0258] In this embodiment, the lens assembly 30 and the fill light assembly 40 are placed side by side in the horizontal direction, thereby eliminating the possibility that flying insects and spiders attracted by the fill light assembly enter the field of view of the lens assembly 30 due to the influence of gravity.

[0259] Furthermore, in the optical axis direction L, the window 31 of the lens assembly 30 is located in front of the light exit surface 43 of the fill light assembly 40, and the flying insects attracted by the fill light assembly 40 are concentrated near the light exit surface 43. Due to the limitation of the field of view angle of the lens assembly 30, the possibility of the flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 can be minimized. In addition, the light source is at the rear side of the lens assembly 30, and there is no light source within a certain range in front of the lens assembly 30, which will not attract flying insects. Therefore, the number of flying insects in front of the lens assembly 30 is greatly reduced.

[0260] The functions of the sunshade 50 are divided into two types. One is to prevent excessive light from causing glare within the field of view of the lens assembly under sufficient light conditions, especially using the top wall 51 to block the sunlight from above the lens assembly 30; the other is to use the first side wall 52 and the second side wall 53, especially the first side wall 52, to block the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 when the fill light assembly is turned on, thereby preventing flying insects attracted by the fill light assembly from flying around the window 31.

[0261] By utilizing the low friction coefficient characteristic of Teflon, the surface of the light shield 50 is made unfavorable for flying insects or spiders to stay. Combined with the structural characteristics of the light shield 50 and the positional relationship between the fill light assembly and the lens assembly, the camera of this embodiment can minimize the appearance of flying insects attracted by the fill light assembly within the field of view of the lens assembly, thereby improving the picture shooting quality of the camera.

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.
