Description

Technical Field

[0001] This application relates to the technical field of eye masks, and particularly to a camera component. Background Art

[0002] Since eye masks can fit well with the eyes, improve eye comfort, and can assist in obtaining high-quality images, etc., they are widely used in fields such as cameras and ophthalmic detection equipment. Taking a fundus camera as an example, it irradiates light on the pupil to obtain a retinal image of the human eye with reflected light from the fundus, so that medical staff can check for fundus diseases or assist medical staff in judging the conditions of other organs. However, due to the narrowness of the eye pupil, if the fundus camera shakes when obtaining the retinal image of the human eye, the obtained image may be blurred. For this reason, an eye mask can be installed at the front end of the lens barrel of the fundus camera. Thus, when performing ophthalmic examinations using the fundus camera, the eye mask can be abutted against the eyes to prevent the fundus camera from shaking, thereby ensuring the stability of the quality of the obtained retinal image of the human eye. The eye mask can protect the patient's eyes, prevent light from directly irradiating the eyes, and at the same time prevent hands or other objects from touching the camera lens.

[0003] Since it is often necessary to correspondingly adjust the position of the eye mask when using the fundus camera to examine the left and right eyes respectively, in related technologies, the fundus camera and the eye mask are often connected by a snap connection or a socket connection, and the disassembly and installation of the eye mask are complex, which affects the examination efficiency.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] The embodiments of this application are described by taking a fundus camera as an example. The fundus camera includes a camera assembly 100. Please refer to Figure 1 , which is an exploded example diagram of the camera assembly 100 provided by the embodiments of this application. As Figure 1 shown, the camera assembly 100 includes an eyepiece assembly 10 and a barrel assembly 20. The barrel assembly 20 includes a front barrel cover assembly 21, a barrel 22, and a rear barrel cover 23. The front barrel cover assembly 21 includes a front barrel cover 211. The front barrel cover 211 is fixedly connected to the rear barrel cover 23. The barrel 22 is sleeved on the rear barrel cover 23 and fixedly connected to the front barrel cover 211. The front barrel cover assembly 21 further includes magnetic elements 212. The magnetic elements 212 are fixed on both sides of the front barrel cover 211. The eyepiece assembly 10 includes an eyepiece body 11 and magnetic attracting elements 12. The magnetic attracting elements 12 are fixed on both sides of the eyepiece body 11. The magnetic elements 212 and the magnetic attracting elements 12 attract each other under the action of a magnetic field, guiding the eyepiece body 11 to be connected to the front barrel cover 211 according to a preset positioning direction. Among them, the eyepiece body 11 is fixed to the front barrel cover 211 of the barrel assembly 20 by a magnetic attraction joining method, which is convenient for adjusting the position of the eyepiece body 11, improving the speed of removing, pulling out, and installing the eyepiece. Moreover, under the action of the magnetic field, the eyepiece body 11 can be guided to be connected to the front barrel cover 211 according to a preset positioning direction, without repeatedly adjusting the positioning angle of the eyepiece body 11.

[0038] In some embodiments, when the eyepiece body 11 is connected to the front barrel cover 211 according to a preset positioning direction, the eyepiece body 11 can be fitted to the eye socket of the eye to be measured. For example, the preset positioning direction includes the direction of the eyepiece body 11 relative to the front barrel cover when the eyepiece body 11 is respectively fitted to the eye sockets of the left eye and the right eye.

[0039] In some embodiments, please refer to Figure 2 , which is an example diagram of the position of the eyepiece body 11 provided by the embodiments of this application. As Figure 2As shown, when the fundus camera is used to complete the detection of one eye and it is necessary to switch to the detection of the other eye (for example, the left eye is switched to the right eye), in order to fit the eye on the other side, the eye mask body 11 needs to be adjusted accordingly. In the embodiment of the present application, the front cover 211 of the lens barrel is equipped with a magnetic element 212 and the eye mask body 11 is equipped with a magnetic element 12, so that the front cover 211 of the lens barrel and the eye mask body 11 can be connected under the magnetic attraction force of the magnetic element 212 and the magnetic element 12. By rotating the eye mask body 11, the position of the eye mask body 11 can be adjusted, avoiding repeated disassembly. In the process of adjusting the eye mask body 11 so that the eye mask body 11 switches from fitting on one eye to fitting on the other eye, for example, when the eye mask body 11 switches from fitting on the left eye to fitting on the right eye, the right eye is used as the eye to be tested, and the preset positioning direction is the direction in which the eye mask body 11 fits the right eye, the eye mask body 11 is connected to the orientation of the front cover 211 of the lens barrel. Since the magnetic element 212 assembled in the front cover 211 of the lens barrel and the magnetic attraction element 12 assembled in the eye mask body 11 can attract and coordinate with each other under the action of the magnetic field, when adjusting the position of the eye mask body 11, there is no need to manually adjust the eye mask body 11 to a preset positioning direction. Under the action of the magnetic field, the magnetic element 212 and the magnetic attraction element 12 attract each other and can guide the eye mask body 11 to rotate a certain angle so that the eye mask body 11 is connected to the front cover 211 of the lens barrel according to the preset positioning direction.

[0040] In some embodiments, the eye mask body 11 is connected to the front cover 211 of the lens barrel assembly 20 by magnetic attraction. No special joint is required for the eye mask body 11 and the front cover 211 of the lens barrel, which can shorten the length of the eye mask body 11 and reduce the size of the eye mask body 11.

[0041] In some embodiments, the lens barrel front cover 211, the lens barrel rear cover 23 and the lens barrel 22 can be connected to each other by threads. A waterproof gasket can be provided at the junction of the lens barrel rear cover 23 and the lens barrel front cover 211 to provide waterproof, dustproof and better sealing function.

[0042] In some embodiments, the magnetic element 212 includes but is not limited to magnets, such as N50M Ruthenium-Fe-B magnets with high magnetic permeability, corrosion resistance, and high temperature resistance. The magnetic element 12 includes but is not limited to metal materials with high magnetic permeability, such as SUS1010 steel.

[0043] In some embodiments, a coating, such as an epoxy coating, may be added to the surface of the magnetic element 212 to increase adhesion to the double-sided adhesive 2114 and prevent the double-sided adhesive 2114 from falling off.

[0044] In some embodiments, the front cover 211 of the lens barrel can be made of a non-magnetic metal material or a non-metallic material, such as an aluminum alloy material, and can be provided with a relatively narrow wall thickness to avoid affecting the magnetic attraction effect between the magnetic element 212 and the magnetic attracting element 12.

[0045] In some embodiments, the contour of the eyepatch body 11 is circular, without light path obstruction, which can ensure the clarity of the fundus image captured.

[0046] In some embodiments, please refer to Figure 3 , which is a schematic diagram of the eyepatch assembly 10 provided by the embodiment of the present application. As Figure 3 shown, the eyepatch body 11 includes a hard rubber part 111 and a soft rubber part 112. The hard rubber part 111 and the soft rubber part 112 are combined by a two-color molding process to form the eyepatch body 11, which can avoid light leakage of the eyepatch body 11. Among them, the hard rubber part 111 is used to fix the eyepatch body 11, so that the flash of the fundus camera can enter the pupil of the eye to be measured, avoiding the situation that the eyepatch body 11 cannot be fixed and being skewed when fitting with the eye to be measured, resulting in the deviation of the optical axis of the flash and insufficient light input, affecting the quality of the captured fundus image. The soft rubber part 112 is used to fit with the eye socket of the eye to be measured. Through the two-shot molding design of the hard rubber part 111 and the soft rubber part 112 of the eyepatch body 11, the size of the eyepatch can be reduced, the weight of the eyepatch body 11 can be reduced, the structure is simpler, and the light path can be ensured not to be affected.

[0047] In some embodiments, the soft rubber part 112 adopts a circular contour design with a uniform thickness and a curved surface, with uniform stress and the same amount of deformation. When the soft rubber part 112 fits with the eye socket of the eye to be measured, the soft rubber material of the soft rubber part 112 deforms due to pressure, which can make the eyepatch body 11 fit tightly with the eye socket of the eye to be measured and is not easy to leak light and generate gaps.

[0048] In some embodiments, the magnetic attracting element 12 is fixed on both sides of the hard rubber part 111. The magnetic element 212 and the magnetic attracting element 12 attract each other to guide the hard rubber part 111 to be connected to the front cover 211 of the lens barrel in a preset positioning direction.

[0049] In some embodiments, as Figure 3 shown, the eyepatch body 11 includes a concave side wing 113 and a convex side wing 114. Through the design of the eyepatch body 11 based on ergonomics, when the eyepatch body 11 is connected to the front cover 211 of the lens barrel in a preset positioning direction and the eyepatch body 11 fits with the eye socket of the eye to be measured, the concave side wing 113 fits with the inner corner area of the eye to be measured and the convex side wing 114 fits with the outer corner area of the eye to be measured. In some embodiments, the concave side wing 113 and the convex side wing 114 are asymmetrically designed.

[0050] In some embodiments, the inner canthus of the eye to be measured can be the canthus of the eye to be measured near the nose, and the outer canthus of the eye to be measured can be the canthus of the eye to be measured near the ear. Since the human eye is bilaterally symmetrical, when the fundus camera captures fundus images of the left and right eyes respectively, the eye mask body 11 needs to be rotated 180 degrees so that when the eye mask body 11 is fitted into the eye socket of the left eye, the concave side wings 113 are fitted into the inner canthus of the left eye and the convex side wings 114 are fitted into the outer canthus of the left eye. Alternatively, when the eye mask body 11 is fitted into the eye socket of the right eye, the concave side wings 113 are fitted into the inner canthus of the right eye and the convex side wings 114 are fitted into the outer canthus of the right eye.

[0051] In some embodiments, see Figure 4 , is an exploded view of the eye mask assembly 10 provided in an embodiment of the present application, as shown Figure 4 As shown, the rear end of the eye mask body 11, i.e., the hard plastic portion 111, is provided with grooves 1111 that are symmetrically distributed along the center. Magnetic elements 12 are fixed in the grooves 1111, so that the magnetic elements 12 are located on both sides of the eye mask body 11, i.e., on both sides of the hard plastic portion 111, and are distributed symmetrically along the center.

[0052] In some embodiments, see Figure 5 , is an exploded view of the lens barrel front cover assembly 21 provided in an embodiment of the present application. Figure 5 As shown, the inner side of the lens barrel front cover 211 is provided with centrally symmetrically distributed slots 2111 , and the magnetic elements 212 are respectively fixed to the slots 2111 , so that the magnetic elements 212 are located on both sides of the lens barrel front cover 211 and are centrally symmetrically distributed.

[0053] In some embodiments, as Figure 5 As shown, the lens barrel front cover assembly 21 may further include a double-sided adhesive 2114, such as a pressure sensitive adhesive (PSA), one side of the double-sided adhesive 2114 being connected to the magnetic element 212, and the other side being connected to the lens barrel front cover 211, for fixing the magnetic element 212 to the lens barrel front cover 211. In other embodiments, the magnetic element 212 may be fixed to the lens barrel front cover 211 by applying adhesive on the surface of the magnetic element 212 or the lens barrel front cover. The embodiment of the present application does not limit the fixing method of the magnetic element 212.

[0054] In some embodiments, see Figure 6 , is a partial cross-sectional view of the camera assembly 100 provided in an embodiment of the present application. Figure 6As shown, the magnetic element 212 and the magnetic attracting element 12 attract each other, so that the eye mask body 11 is connected to the front cover 211 of the lens barrel in accordance with a preset positioning direction. Each magnetic element 212 attracts a magnetic attracting element 12, and a clearance position 30 is formed at the position where each magnetic element 212 is aligned with a magnetic attracting element 12. The clearance positions 30 are centrosymmetrically distributed, and are used to limit the eye mask body 11, so that the eye mask body can only be installed in two orientations (for example, the orientations that fit the left eye and the right eye respectively).

[0055] In some embodiments, please refer to Figure 7 , which is a partially enlarged cross-sectional view of the clearance position 30 provided by the embodiment of the present application. As Figure 7 shown, the depth of the groove 1111 in the eye mask body 11 is greater than the height of the magnetic attracting element 12. After the magnetic attracting element 12 is fixed in the groove 1111, there is a gap 31 between the magnetic attracting element 12 and the bottom surface 119 of the eye mask body 11, so that when the magnetic element 212 and the magnetic attracting element 12 attract each other and are aligned in position, the eye mask body 11 can be attached to the front cover 211 of the lens barrel prior to the magnetic attracting element 12, thereby avoiding light leakage at the joint of the magnetic element 212 and the magnetic attracting element 12 and affecting the clarity and accuracy of the fundus image.

[0056] In some embodiments, the magnetic attracting element 12 can be fixed in the grooves 1111 on both sides of the eye mask body 11 by means of inserts.

[0057] In some embodiments, in view of the high sensitivity of the fundus camera to light, in order to further avoid light leakage at the connection between the eye mask body 11 and the front cover 211 of the lens barrel, as Figure 8 shown, in the embodiment of the present application, a male stop 2112 is provided on the outer side of the front cover 211 of the lens barrel. As Figure 9 shown, at the rear end of the eye mask body 11, that is, the hard rubber part 111, a female stop 1112 is provided. Both the male stop 2112 and the female stop 1112 are semicircular designs. The male stop avoids the position corresponding to the magnetic element 212, and the female stop 1112 avoids the position corresponding to the magnetic attracting element 12. The male stop 2112 and the female stop 1112 are fastened and fixed, so that the front cover 211 of the lens barrel and the eye mask body 11 are closely attached, thereby achieving the effect of preventing light leakage.

[0058] In some embodiments, as Figure 10 shown, a first marking structure 116 is designed on the eye mask body 11, and the first marking structure 116 is used to mark the position of the magnetic attracting element 12. As Figure 11As shown, the front cover 211 of the lens barrel is designed with a second marking structure 2113, and the second marking structure 2113 is used to mark the position of the magnetic component 212. By identifying the first marking structure 116 and the second marking structure 2113, the positions of the magnetic attracting component 12 and the magnetic component 212 can be quickly determined, thereby determining the placement position of the eye mask body 11, which is convenient for improving the installation speed of the eye mask body 11.

[0059] In some embodiments, such as Figure 3 or Figure 9 As shown, the eye mask body 11 includes an observation hole 115. When the eye mask body 11 is connected to the front cover 211 of the lens barrel in a preset positioning direction, the central axis of the observation hole 115 is collinear with the optical axis of the lens barrel assembly 20. As Figure 12 As shown, after applying force at point F, the eye mask body 11 fits with the eye socket of the eye to be measured, the concave side wings fit with the inner corner area of the eye to be measured, and the convex side wings 114 fit with the outer corner area of the eye to be measured. At this time, based on the human factors engineering design of the eye mask body 11, the central axis of the observation hole 115, the optical axis of the lens barrel assembly 20 (not fully shown in the figure), and the optical axis of the eye to be measured are collinear, so that the light of the flash of the fundus camera can fully pass through the pupil of the eye to be measured and shine into the fundus, thereby improving the quality of the captured fundus image.

[0060] In some embodiments, such as Figure 12 As shown, it is a schematic diagram of the eye mask body 11 provided by the embodiment of the present application fitting with the eye socket of the eye to be measured. When the eye mask body 11 fits with the eye socket of the eye to be measured, the X-axis of the face forms a 90-degree angle with the bottom surface 119 of the eye mask body 11. The X-axis is an imaginary axis passing through the face and perpendicular to the face direction.

[0061] In some embodiments, such as Figure 13 As shown, the eye mask body 11 includes a first fitting surface 117, a second fitting surface 118, and a bottom surface 119. The first fitting surface 117 can be a soft rubber surface inside the concave side wing 113, the second fitting surface 118 can be a soft rubber surface inside the convex side wing 114, and the bottom surface 119 is the surface of the rear end of the eye mask body 11 close to the front cover 211 of the lens barrel. There is a point A on the first fitting surface 117 and a point B on the second fitting surface 118. When the point A fits with the inner corner area of the eye to be measured, the point B fits with the outer corner area of the eye to be measured, and the included angle between the optical axis of the pupil of the eye to be measured and the bottom surface 119 of the eye mask body 11 is 90 degrees.

[0062] In some embodiments, such as Figure 13 As shown, the distance from point A to the bottom surface 119 is H1, the distance from point B to the bottom surface 119 is H2, and H1 and H2 are in proportion or have a certain difference. The proportion or difference between H1 and H2 is obtained based on human factors engineering design.

[0063] In some embodiments, the overall contour of the blindfold body 11 and the viewing hole 115 are circular, without light path obstruction, which can ensure the clarity during fundus photography.

[0064] The embodiment of the present application provides a camera assembly 100. By using magnetic attraction as the engagement method between the camera and the blindfold, the speed of detaching and installing the blindfold can be effectively improved. Moreover, with the magnetic attraction engagement method between the camera and the blindfold, the orientation of the blindfold can be switched by rotating the blindfold, enabling the blindfold to fit the left and right eyes that are symmetrical to each other respectively, without the need to frequently disassemble and reinstall the blindfold.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the implementation solutions of the present application rather than to limit. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
