DETAILED DESCRIPTION

[0051] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0053] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0054] Example 1

[0055] Reference Figure 1 , Attachment Figure 2 And attached Figure 3 The lens cover provided by the embodiment of the present application comprises a mounting seat 1, a plurality of shielding blades 2 and a driving member 3, wherein the mounting seat 1 has a first central opening 11; the plurality of shielding blades 2 are movably connected to the mounting seat 1 in sequence around the axial direction of the first central opening 11, and the edges of the plurality of shielding blades 2 can be spliced ​​with each other; the driving member 3 has a second central opening 31, and the driving member 3 is movably connected to the shielding blade 2 at a side of the shielding blade 2 away from the mounting seat 1, so that the second central opening 31 and the first central opening 11 are coaxial, and the driving member 3 is rotatably arranged relative to the mounting seat 1;

[0056] In which, the driving member 3 is located in the first position, the edges of several of the shielding blades 2 are spliced ​​with each other and shield the second middle opening 31, and the driving member 1 rotates to the second position, and several of the shielding blades 2 rotate around the axial direction of the first middle opening 11 and swing apart to reveal the second middle opening 31.

[0057] Specifically, in order to solve the problem that the existing camera shielding structure is complex, requires a large space, or is even easy to lose, which affects the user experience, the present embodiment provides a lens hood, which is overlapped with the camera, and realizes the shielding and unblocking of the second middle opening 31 and the second middle opening 11 by swinging a plurality of blades 2 between the mounting seat 1 and the driving member 3, so as to achieve the effect of shielding the lens and revealing the lens. When the lens is blocked or revealed, the blades swing between the mounting seat 1 and the driving member 3, there is no translational movement, and no extra space will be occupied next to or on the side of the lens.

[0058] The lens cover provided in this embodiment can be arranged in conjunction with an external camera or a camera of an electronic device, and its shape and size can be designed and adjusted according to the size of the camera.

[0059] Among them, the mounting seat 1 is a rigid structure, which is used to connect the lens cover and the housing of the camera, or to connect the lens cover and the housing of the electronic device. The connection method can be but not limited to screw connection, bonding, clamping, etc. In this embodiment, the mounting seat 1 has a first central opening 11, which is used to correspond to the lens so that the lens can be exposed in the lens cover. Correspondingly, the second central opening 31 on the driving member 3 is coaxial with the first central opening 11, so that the lens can be exposed to the outside through the lens cover for image acquisition. Then the size of the first central opening 11 and the second central opening 31 should be greater than or equal to the size of the lens to ensure the working requirements of the lens. It can be understood that the size of the first central opening 11 can also be greater than the size of the second central opening 31. The shape and size of the first central opening 11 can be designed and adjusted according to actual needs, for example: round, square, etc. Correspondingly, the mounting seat 1 can be an annular structure, which can be but not limited to a circular ring, a square ring, etc.

[0060] The shielding blade 2 is a rigid plate-like structure made of an opaque material, so that it can shield the lens after a number of shielding blades 2 are spliced ​​together. The number and shape of the shielding blades 2 can be designed and adjusted according to actual needs. Figures 1 to 3 The four arc-shaped petals shown can also be fan-shaped, triangular, etc., or 6, 8, etc.; when a plurality of shielding blades 2 are spliced ​​together, they are spliced ​​together at the center of the second middle opening 31. In this embodiment, the two sides of the shielding blade 2 are movably connected to the mounting seat 1 and the driving member 3, so that the shielding blade 2 can rotate and swing relative to the mounting seat 1 with the rotation of the driving member 3, thereby realizing mutual splicing and mutual separation. The plurality of shielding blades 2 can be spliced ​​when the driving member 3 rotates clockwise around the axial direction of the second middle opening 31 or when it rotates counterclockwise.

[0061] The driving member 3 is a rigid structure, which may be, but not limited to, a plate-like structure, a groove-like structure, a frame structure, etc. A receiving space can be formed between the driving member 3 and the mounting seat 1 to accommodate the shielding blades 2. The driving member 3 and the mounting seat 1 may be, but not limited to, connected by a snap connection to realize the rotation of the driving member 3 relative to the mounting seat 1. When the driving member 3 is located at the first position relative to the mounting seat 1, the edges of several shielding blades 2 can be spliced ​​with each other and shield the second middle opening 31 to prevent privacy leakage; when the driving member 3 rotates to the second position relative to the mounting seat 1, several shielding blades 2 swing around the axial direction of the second middle opening 31 to spread out and reveal the second middle opening 31; in this process, the direction of the driving member 3 rotating from the first position to the second position can be designed and adjusted according to actual needs, and can be clockwise or counterclockwise.

[0062] According to the above, the lens hood provided by the present application, through the rotation of the driving member 3, makes several shielding blades 2 swing and splice or spread out, so as to achieve shielding or exposure of the second central opening 31. The driving member 3 and the mounting seat 1 clamp the shielding blades 2 in the middle, which neither causes the exposure of structural parts nor the need to protrude the overall lever structure of the equipment, which greatly improves the appearance of the product while effectively saving space around the lens; thereby solving the problem that the existing shielding structure is complex, requires a large space and is even easy to lose, affecting the user experience.

[0063] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

[0064] Further, see Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 And attached Fig. 9 In the lens hood provided in this embodiment, in a specific implementation, the shielding blade 2 is provided with a first guide groove 21 on the side facing the mounting seat 1, and the shielding blade 2 is provided with a first limiting column 22 on the side facing the driving member 3; the mounting seat 1 is provided with a plurality of second limiting columns 12 on the side facing the shielding blade 2, and the second limiting columns 12 correspond to the first guide grooves 21 one by one, so that the second limiting columns 12 can drive the shielding blade 2 to swing back and forth along the first guide grooves 21; the driving member 3 is provided with a plurality of second limiting grooves 32 on the side facing the shielding blade 2, and the second limiting grooves 32 correspond to the first limiting columns 22 one by one, so that the first limiting column 22 can rotate in the second limiting groove 32 around the axial direction parallel to the first middle opening 11.

[0065] Specifically, in order to realize that the shielding blade 2 can rotate and swing with the driving member 3 around the second middle opening 31 when the driving member 3 rotates, in this embodiment, a first guide groove 21 and a first limiting column 22 are respectively provided on both sides of the shielding blade 2, a second limiting column 12 is provided on the mounting seat 1, and a second limiting groove 32 is provided on the driving member 3; refer to the attached Figure 3 When the driving member 3 rotates counterclockwise, the first limiting column 22 of the shielding blade 2 rotates counterclockwise with the second limiting groove 32 and can rotate in the second limiting groove 32 in a direction parallel to the axial direction of the second middle opening 31, and at the same time, the first guide groove 21 of the shielding blade 2 can cooperate with the second limiting column 12 to swing, so that the shielding blade 3 can swing from the axis of the second middle opening 31 to the edge to achieve the effect of revealing the second middle opening 31. It can be understood that the first limiting column 22 and the second limiting column 12 are both rigid structures, which can be integrated with the corresponding main body or assembled by pasting, welding, etc. In addition, the corresponding relationship between the clockwise and counterclockwise rotation of the driving member 3 and the splicing and moving away from the shielding blade 2 can be designed and adjusted according to actual needs, for example: adjusting the extension direction of the first guide groove 21. In this embodiment, the first limiting column 22 can be set at a position close to the end of the length direction of the shielding blade 2, thereby ensuring that the first limiting column 22 can be blocked by the driving member 3 when the second middle opening 31 is exposed online, ensuring the appearance.

[0066] Furthermore, for the corresponding relationship between the clockwise and counterclockwise rotation of the driving member 3 and the splicing and separation action of the shielding blade 2, the present embodiment may have the following two setting modes:

[0067] The first one, refer to the attached Fig.10 and attached Fig.11 , the first guide groove 21 and the length direction of the shielding blade 2 meet the parallel condition, and when the edges of several shielding blades 2 are spliced ​​with each other and shield the second middle opening 31, the second limiting column 12 is placed in the first guide groove 21 along its length direction at one end facing the first limiting column 22.

[0068] Specifically, the parallel condition here means being parallel or approximately parallel. Although the shielding blade 2 can be set to a variety of different shapes, no matter what shape it is, it has a relative length direction and width direction, for example: Fig. 9 The illustrated arc-shaped petal-shaped shielding blade has a length direction that is roughly the left-right direction in the figure, and a width direction that is roughly the up-down direction in the figure; for example, when the shielding blade 2 is fan-shaped, one end of its circle center must be spliced ​​with the axis of the second middle opening 31, and then its length direction is its radial direction, and its width direction is a direction perpendicular to its radial direction. Fig.10In this embodiment, the first guide groove 21 is set to be parallel to the length direction of the shielding blade 2, and then when the driving member 3 rotates counterclockwise, the first limiting post 22 of the shielding blade 2 rotates in the second limiting groove 32 and the shielding blade 2 swings toward the edge of the second middle opening 31, so that the second limiting post 12 moves in the first guide groove 21 and can rotate counterclockwise around the axial direction of the second middle opening 31. At this time, it is equivalent to the first limiting post 22 moving counterclockwise away from the second limiting post 12 matched on the shielding blade 2 where it is located. In order to cooperate with the above action, the second limiting post 12 moves from the first guide groove 21 toward one end of the first limiting portion 22 to the end of the first guide groove 21 away from the first limiting post 22, that is, Fig.11 status.

[0069] The second type, see attached Fig.12 and attached Fig.13 , the first guide groove 21 and the width direction of the shielding blade 2 meet the parallel condition, and when the edges of several shielding blades 2 are spliced ​​with each other and shield the second middle opening 31, the second limiting column 22 is placed at one end of the first guide groove 21 away from the first limiting column 22 along its length direction.

[0070] Specifically, the parallel condition and the length and width directions of the shielding blade 2 can be referred to the explanation of the first case above, and will not be elaborated here. Fig.12 In this embodiment, the first guide groove 21 is set to be parallel to the width direction of the shielding blade 2, and then when the driving member 3 rotates clockwise, the first limiting post 22 of the shielding blade 2 rotates in the second limiting groove 32 and can rotate clockwise around the axial direction of the second middle opening 31, and the shielding blade 2 swings toward the edge of the second middle opening 31 so that the second limiting post 12 moves in the first guide groove 21. At this time, it is equivalent to the first limiting post 22 approaching the second limiting post 12 on the shielding blade 2 where it is located clockwise. In order to cooperate with the above action, the second limiting post 12 moves from the end of the first guide groove 21 away from the first limiting portion 22 to the end of the first guide groove 21 toward the first limiting post 22, that is, Fig.13 status.

[0071] Further, see Attachment Figure 5In the lens hood provided in this embodiment, in a specific implementation, the driving member 3 includes a first plate member 33 and a second plate member 34; the first plate member 33 is provided with a second middle opening 31, and the first side of the first plate member 33 is movably connected to the shielding blade 2; the second plate member 34 extends from the first side of the first plate member 31 around the circumference of the first plate member 33 toward the first side of the first plate member 33 to enclose a accommodating space between the second plate member 34 and the first plate member 33; wherein the mounting seat 1 is detachably arranged in the accommodating space.

[0072] Specifically, in order to achieve the appearance of the installation of the shielding blades, the driving member 3 is set in the present embodiment to include a first plate 33 and a second plate 34. The first plate 33 is a rigid annular structure, and the second plate 34 is a cylindrical structure, so that the first plate 33 is a cover plate with an opening at one end of the second plate 34 to form a cylindrical structure with openings at both ends, thereby forming a accommodating space in the cylinder. Correspondingly, the mounting seat 1 can be detachably connected to the second plate 34. It is understandable that in order to improve the convenience of operation of the driving member 3, elements such as patterns, protrusions, grooves, lines, LOGO, etc. that increase the surface roughness can be set on the outer surface of the second plate 34 to increase friction and reduce the difficulty of driving rotation.

[0073] Further, see Attachment Figure 5 In the lens cover provided in this embodiment, in a specific implementation, a third limiting groove 35 is provided on the inner wall of the second plate 34 ; and a limiting plate 13 adapted to the third limiting groove 35 is provided on the mounting seat 1 .

[0074] Specifically, in order to realize the detachable connection between the second plate 34 and the mounting seat 1, the third limiting groove 35 and the limiting plate 13 are correspondingly provided in this embodiment; the limiting plate 13 is in the form of extending outward from the second plate 34 along the radial direction of the second plate 34. In this embodiment, the limiting plate 13 can be provided as a plastic part alone, or the limiting plate 13 and the mounting seat 1 can be provided as a plastic part as a whole, so that the limiting plate 13 can be connected to the third limiting groove 35 by a small amount of deformation. The number of the third limiting groove 35 and the limiting plate 13 can be designed and adjusted according to actual needs, for example: Figure 5 As shown, three are arranged at intervals around the second middle opening 31 .

[0075] Further, see Attachment Figure 2 and attached Figure 5In the lens hood provided in this embodiment, in a specific implementation, the mounting seat 1 includes a stacked first mounting ring 14 and a second mounting ring 15; the opening of the first mounting ring 14 is the first middle opening 11, and the side of the first mounting ring 14 facing away from the second mounting ring 15 is used to movably connect the shielding blade 2, and the side of the first mounting ring 14 facing the second mounting ring 15 is provided with a connecting portion 16 for connecting the camera module; the second mounting ring 15 is used to detachably connect the driving member 3.

[0076] Specifically, in order to enable the driving member 3 to rotate relative to the mounting seat 1 and the driving member 3 to be clamped on the mounting seat 1, in this embodiment, the mounting seat 1 is configured to include a stacked first mounting ring 14 and a second mounting ring 15, the first mounting ring 14 is a rigid annular structure, and at least the limiting plate 13 on the second mounting ring 15 can be slightly deformed; second limiting columns 12 and connecting portions 16 are respectively arranged on both sides of the first mounting ring 14, and the connecting portion 16 can be but is not limited to a bolt hole or a bolt column, so that the first mounting ring 14 remains fixed when the driving member 3 rotates, and is used to guide the shielding blade 2. The number of connecting portions 16 can be designed and adjusted according to actual needs; at the same time, the second mounting ring 15 is clamped with the driving member 3 and can rotate with the driving member 3.

[0077] Further, see Attachment Figure 2 In the lens hood provided in this embodiment, in a specific implementation, the second mounting ring 15 has a third central opening, the third central opening is coaxial with the first central opening 11, and the diameter of the third central opening is larger than the diameter of the first central opening 11, so that the connecting portion 16 can pass through the third central opening.

[0078] Specifically, in order to avoid interference between the connecting portion 16 and the second mounting ring 15, in this embodiment, the diameter of the third middle opening can be set to be larger than the diameter of the first middle opening 11, so that part of the radial dimension of the first mounting ring 14 will be exposed by the third middle opening, and the connecting portion 16 can pass through this part of the first mounting ring 14 and at the same time pass through the third middle opening to complete the connection with the camera module, thereby ensuring that the connecting portion 16 will not interfere with the rotation of the second mounting ring 15; in this embodiment, it is not difficult to understand that the outer diameter of the second mounting ring 15 cooperates with the driving member 3, and the difference between the inner and outer diameters of the second mounting ring 15 can be designed and adjusted according to actual needs. It can be designed to be smaller to reduce the difficulty of disassembly and assembly, or it can be set to be larger to ensure the connection strength.

[0079] Further, see Attachment Figure 5 and attached Figure 6 In the lens cover provided in this embodiment, in a specific implementation, the radial dimension of the driving member 3 is at least twice the radial dimension of the second middle opening 31 .

[0080] Specifically, in this embodiment, the diameter of the second central opening 31 is equal to the diameter of the lens, which is a. When the shielding blade 2 shields the second central opening 31, its exposed size in the radial direction of the second central opening 31 is a / 2. When it is spread out and hidden behind the driving member 3, the driving member 3 at least shields a / 2 of the size, and thus the outer diameter of the driving member 3 is at least twice the diameter of the second central opening 31. Accordingly,

[0081] Further, see Attachment Figure 4 In the lens cover provided in this embodiment, in a specific implementation, a dust cover plate 4 is provided on the side of the driving member 3 facing away from the shielding blade 2 .

[0082] Specifically, the dust cover 4 is a rigid structure, which can be but not limited to glass or plastic. In this embodiment, the dust cover 4 is an annular structure, which has a fourth middle opening corresponding to the second middle opening 31, and the fourth middle opening is equal in size and coaxial with the second middle opening 31. The dust cover 4 covers the first plate 33 of the driving member 3. The dust cover 4 is made of an opaque material to ensure the appearance and play a dustproof role. The side of the dust cover 4 away from the shielding blade 2 can be provided with a pattern or a LOGO to increase the visual effect.
