Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings that are required to be used in the embodiments will be briefly described below. It is apparent that the drawings in the following description are only some embodiments of the present invention, and that other drawings may be obtained from these drawings without inventive effort for a person of ordinary skill in the art.
In describing embodiments of the present invention, the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in terms of orientation or positional relationship shown in the drawings for convenience of description and simplicity of description only, and do not denote or imply that the devices or elements in question must have a particular orientation, be constructed and operated in a particular orientation, so that the above terms are not to be construed as limiting the invention.
The present invention will be described in detail below with reference to the drawings and the specific embodiments, which are not described in detail herein, but the embodiments of the present invention are not limited to the following embodiments.
Referring to fig. 1, the dust-proof structure 1 of the present invention includes a dust-proof body 11 and a connecting portion 12, the connecting portion 12 being located at one end of the dust-proof body 11. The camera module of the invention mainly refers to a vehicle-mounted camera module, and can be used for other purposes, and the camera module comprises a shell 2 (comprising an upper shell 21 and a lower shell 22), a lens 3, a photosensitive chip 4 (i.e. SENSOR) and a circuit board 5. Wherein, sensitization chip 4, circuit board 5 and dustproof construction 1 all are located casing 2, and dustproof construction 1 is connected with camera lens 3 and sensitization chip 4 respectively, and sensitization chip 4 sets up on circuit board 5 together with other electronic components. In the invention, the dustproof body 11 is an annular thin wall to form a dustproof area A, thereby realizing the dustproof between the upper part of the photosensitive chip 4 and the lens 3 and improving the image quality. The connection portion 12 is cylindrical, so that it can be connected to the photosensitive chip 4 or the lens 3 in the image capturing module, and of course, the shape of the connection portion 12 should also be adapted to the photosensitive chip 4 or the lens 3 being square. Thus, after the connecting portion 12 is provided, the matching precision of the dustproof structure 1 and the photosensitive chip 4 is high, and the imaging surface is not easy to be blocked.
In the embodiment shown in fig. 1 and 2, the inner diameter and the outer diameter of the dust-proof body 11 are each gradually reduced from the upper end toward the lower end, and the dust-proof body is formed in a horn shape having a circular cross section, thereby providing a certain elasticity and being easily shaped. When mounted, the small-caliber end of the dustproof body 11 faces the photosensitive chip 4. As shown in fig. 1, in the present embodiment, the connection portion 12 is located at the small diameter end of the dust-proof body 11. In addition, the small-caliber end of the dustproof body 11 is provided with a wrapping part 13 extending outwards, and the connecting part 12 is connected to the outer side of the wrapping part 13. It should be ensured that the wrapping 13 can expose the imaging area of the photosensitive chip 4. The photosensitive chip 4 is located in the connecting portion 12 and abuts against the wrapping portion 13. The large-caliber end of the dustproof body 11 directly abuts against the plane at the bottom of the lens 3. As shown in fig. 2, in the present embodiment, the connection portion 12 is located at the large diameter end of the dust-proof body 11, and the lens 3 is abutted against the connection portion 12 and connected to the outside of the connection portion 12. In the present embodiment, the small-caliber end of the dust-proof body 11 directly abuts against the photosensitive chip 4.
In the embodiment shown in fig. 3 and 5, the inner diameter and the outer diameter of the dust-proof body 11 are gradually reduced from the middle to the two ends, and the dust-proof body is corrugated, so that the dust-proof body has corresponding elasticity and is suitable for the situation that the bottom of the lens 3 is small in size. In both embodiments, the difference between the upper and lower diameters of the dust-proof body 11 is small, so that the lower end of the dust-proof body 11 has the wrapping portion 13 extending inward. As shown in fig. 3, in the present embodiment, the connection portion 12 is located at the lower end of the dust-proof body 11, and the photosensitive chip 4 is located in the connection portion 12 and abuts against the wrapping portion 13. The upper end of the dust-proof body 11 directly abuts against the bottom of the lens 3. As shown in fig. 4, during installation, the dustproof structure 1 is assembled on the photosensitive chip 4, so that the dustproof structure 1 can be kept in contact with the end face of the lens 3 when the lens 3 moves for AA focusing X, Y, Z, thereby playing a role in sealing and dustproof. Of course, the dust-proof structure 1 of the present invention can be applied not only to the AA focusing method but also to the fixed focusing method. As shown in fig. 5, in the present embodiment, the connection portion 12 is located at the upper end of the dust-proof body 11, and the lens 3 is abutted against the connection portion 12 and connected to the inside of the connection portion 12. The lower end of the dust-proof body 11 directly abuts against the photosensitive chip 4. As shown in fig. 6, during installation, the dustproof structure 1 is assembled on the lens 3, so that the lens 3 can keep contact with the end surface of the photosensitive chip 4 when the AA focusing X, Y, Z is carried out, and the dustproof structure 1 plays a role in sealing and dustproof.
Of course, the dust-proof body 11 is specifically horn-shaped or wave-shaped (arc-shaped) and can be selected according to practical requirements, for example, the height difference between the lens and the chip, the lens plane size and the chip imaging plane size can be determined.
In the invention, the contact part of the dustproof structure 1 and other devices (such as a lens) is provided with the ventilation groove (except the dustproof area A), so that the devices can move more smoothly. For example, as shown in fig. 7 and 8, in the first (and third) embodiments, an annular ventilation groove 111 is provided at an end (i.e., at B) of the dust-proof body 11 remote from the connection portion 12, and communication grooves 111a arranged at intervals in the circumferential direction are provided on the inside and outside of the ventilation groove 111, respectively, so as to form a labyrinth groove body that can communicate with the outside. Of course, in the second and fourth embodiments, the ventilation groove 111 is provided at the end of the connection portion 12 away from the dust-proof body 11, and the groove structure is still the labyrinth type.
In the invention, the dustproof structure 1 is made of soft silica gel or rubber, and the like, so that the dustproof structure is matched with the horn-shaped or corrugated structural design, and has certain elasticity, namely, the dustproof structure can be properly compressed and rebounded along the axial direction, and the dustproof structure can be tightly contacted with the lens 3 and the photosensitive chip 4 through tension absorption tolerance, so that the dustproof effect is achieved. And the dust-proof structure 1 is black in color, so that reflection of light can be prevented to avoid affecting imaging quality. In addition, the axial dimension (i.e., vertical height) of the dust-proof body 11 is larger than the distance H between the bottom of the lens 3 and the upper surface of the photosensitive chip 4, so that the dust-proof structure 1 is abutted against the bottom end surface of the lens 3 or the upper surface of the photosensitive chip 4 by adjusting the tolerance in the vertical direction after assembly.
The above description is only one embodiment of the present invention and is not intended to limit the present invention, and various modifications and variations of the present invention will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
