Technical Field

[0001] The present invention relates to an optical device, in particular to a camera device. Background Art

[0002] With the development of technology, camera devices are increasingly used in personal electronic products, automotive fields, medical fields, etc. to capture external images. For example, a camera device can be installed on a vehicle to capture images outside the vehicle for driving assistance.

[0003] Since most products are currently developing towards a trend of being thinner and lighter, camera devices also need to be increasingly miniaturized. In order to allow the camera device to be equipped with a sufficient number of electronic components in a limited space, some camera devices use a method of stacking and fixing multiple circuit boards. However, during the assembly process of the camera device, it is easy for the multiple circuit boards to generate internal stress after assembly due to the manufacturing tolerance of the assembly parts (such as screws or connectors), the assembly tolerance during assembly, or the deviation of the assembly position, which may cause the circuit boards to deform or break. In addition, when the camera device is subjected to external forces (such as external forces generated by falling or vibration), the multiple circuit boards are also easily damaged due to the force. Summary of the invention

[0004] In view of the above, in one embodiment, a camera device is provided, including an outer cover, a lens, a first circuit board, a second circuit board and a stepped screw. The outer cover includes an axial hole and an outer side and an inner side axially opposite to each other. The lens is arranged on the outer side of the outer cover. The first circuit board is located on the inner side of the outer cover, the first circuit board includes a first through hole and an inner surface and an outer surface opposite to each other, the first through hole passes through the inner surface and the outer surface, a photosensitive component is arranged on the inner surface, the photosensitive component is located in the axial hole and corresponds to the lens. The second circuit board is electrically connected to the first circuit board, the second circuit board includes a second through hole and a first surface and a second surface opposite to each other, the first surface faces the outer surface of the first circuit board, the second through hole passes through the first surface and the second surface and corresponds to the first through hole, and the second through hole has a hole edge. The stepped screw includes a head, a connecting column and a stud, the connecting column has a first end and a second end opposite to each other, the first end is connected to the head, and the second end is connected to the stud, wherein the diameter of the head is larger than the diameter of the connecting column, the diameter of the connecting column is larger than the diameter of the stud, the stud passes through the first through hole and is locked on the inner side of the outer cover, the second end of the connecting column abuts against the outer surface of the first circuit board, and there is a first movable gap between the connecting column and the edge of the hole, and there is a second movable gap between the head and the second surface of the second circuit board.

[0005] In summary, according to the camera device of the embodiment of the present invention, a first movable gap is provided between the connecting column of the step screw and the edge of the hole of the second circuit board, and a second movable gap is provided between the head of the step screw and the second surface of the second circuit board, so that the second circuit board still has movable space without being positioned, thereby being able to absorb the internal stress or external force generated after assembly, thereby avoiding damage to the camera device due to the force.

[0063] Various embodiments are provided below for detailed description. However, the embodiments are only used as examples and do not limit the scope of the invention. In addition, some components are omitted in the drawings in the embodiments to clearly show the technical features of the invention. The same reference numerals will be used to represent the same or similar components in all drawings.

[0064] Figure 1 is a stereoscopic diagram of an embodiment of a camera device of the present invention, Figure 2 is an exploded perspective view of an embodiment of a camera device of the present invention, Figure 3 FIG. 2 is another exploded perspective view of an embodiment of a camera device of the present invention. Figures 1 to 3 As shown, in this embodiment, the camera device 1 includes an outer cover 10, a lens 20, a first circuit board 30, a second circuit board 40 and at least one stepped screw 50A. In some embodiments, the camera device 1 can be applied to various electronic products to capture images around the electronic products. For example, the camera device 1 can be applied to electronic products such as automotive products (such as driving recorders, reversing imaging systems or surround imaging systems), mobile devices (such as smart phones, tablet computers or laptops) or cameras.

[0065] like Figures 1 to 3 As shown, the outer cover 10 includes an axial hole 11 and an outer side 12 and an inner side 13 axially opposite to each other. In this embodiment, the axial hole 11 passes through the outer side 12 and the inner side 13 of the outer cover 10, so that the outer cover 10 is annular and hollow, wherein the shape of the axial hole 11 can be designed as a circular hole, an elliptical hole, a square hole or other irregular holes according to actual use needs, which is not limited.

[0066] Figure 4 is a plan view of an embodiment of a camera device of the present invention, Figure 5 for Figure 4 The cross-sectional view along line segment 5-5. Figures 1 to 5 As shown, the lens 20 is disposed on the outer side 12 of the outer cover 10 to correspond to cover one end of the shaft hole 11. In the present embodiment, the lens 20 is fixed to the outer side 12 of the outer cover 10 by means of adhesion, and a partial area of ​​the lens 20 further extends into the shaft hole 11. For example, during the assembly process of the lens 20, a photocurable adhesive layer may be provided around the outer side 12 of the outer cover 10. After the lens 20 is placed on the photocurable adhesive layer and the focal length is adjusted, the photocurable adhesive layer may be irradiated with a specific light. For example, when the photocurable adhesive layer is an ultraviolet light-curable adhesive layer, the photocurable adhesive layer is irradiated with ultraviolet light to pre-cure the photocurable adhesive layer to prevent the lens 20 from shifting. Finally, the pre-cured photocurable adhesive layer is baked to thermally cure the photocurable adhesive layer to form a cured adhesive layer L to fix the lens 20 to the outer side 12 of the outer cover 10. In some embodiments, the lens 20 may be fixed to the outer cover 10 by general adhesive, or the lens 20 may be fixed to the outer side 12 of the outer cover 10 by other methods such as snap fastening, screw locking or welding.

[0067] For example Figures 1 to 5 As shown, in this embodiment, the camera device 1 further includes a lens bushing 60, and the outer side 12 of the outer cover 10 is provided with an assembly portion 15, wherein the assembly portion 15 is a plurality of locking holes 151 and is arranged around the shaft hole 11, and the lens bushing 60 has a plurality of assembly holes 63 corresponding to the plurality of locking holes 151, and the plurality of assembly holes 63 are respectively screwed and assembled to the plurality of locking holes 151 of the assembly portion 15 by a plurality of screws 70, so that the lens bushing 60 is fixed to the outer side 12 of the outer cover 10. The lens 20 is assembled on the lens bushing 60, for example, the lens 20 can be assembled and fixed to the lens bushing 60 by the above-mentioned adhesion, buckle, screw lock or welding, so that the lens 20 is indirectly arranged on the outer side 12 of the outer cover 10 via the lens bushing 60.

[0068] However, the above embodiments are only examples. In some embodiments, the lens bushing 60 may be assembled and fixed to the outer side 12 of the outer cover 10 by other means (such as adhesion or buckle). The lens 20 may also be directly assembled to the outer side 12 of the outer cover 10 without the lens bushing 60, so that the camera device 1 can omit the lens bushing 60.

[0069] like Figures 1 to 5As shown, the first circuit board 30 is located on the inner side 13 of the outer cover 10 and covers the end of the shaft hole 11 away from the lens 20. The first circuit board 30 includes a first through hole 35 and an inner surface 31 and an outer surface 32 opposite to each other, wherein the inner surface 31 is the surface of the first circuit board 30 facing the inner side 13 of the outer cover 10. A photosensitive component 34 is provided on the inner surface 31, and the photosensitive component 34 is located in the shaft hole 11 and corresponds to the lens 20, so that the external light can pass through the shaft hole 11 and focus on the photosensitive component 34 after entering from the lens 20, so that the photosensitive component 34 can sense and obtain an image. The first through hole 35 passes through the inner surface 31 and the outer surface 32 for the corresponding assembly of the step screw 50A, which will be described in detail later.

[0070] In some embodiments, the first circuit board 30 may be provided with conductive circuits and other electronic components (such as a microprocessor, a resistor or a capacitor, etc.), which are omitted here. The photosensitive component 34 may be a charge-coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), or a complementary metal-oxide semiconductor active pixel sensor (CMOS Active pixelsensor).

[0071] like Figures 1 to 5 As shown, the second circuit board 40 is electrically connected to the first circuit board 30, for example, the first circuit board 30 and the second circuit board 40 can be electrically connected to each other through an electrical connector or a circuit. The second circuit board 40 includes a second through hole 45 and a first surface 41 and a second surface 42 opposite to each other. In this embodiment, the second circuit board 40 and the first circuit board 30 are stacked on each other to form a multi-layer circuit board structure, and the first surface 41 of the second circuit board 40 faces the outer surface 32 of the first circuit board 30. The second through hole 45 passes through the first surface 41 and the second surface 42 and corresponds to the first through hole 35, so that the stepped screw 50A can be correspondingly assembled (this will be described in detail later), and the second through hole 45 has a hole edge 451. In some embodiments, the second circuit board 40 may also be provided with a conductive circuit and other electronic components (such as a microprocessor, a resistor or a capacitor, etc.), which are omitted here.

[0072] For example Figures 1 to 5As shown, in this embodiment, a first electrical connector 33 is provided on the outer surface 32 of the first circuit board 30, and a second electrical connector 43 is provided on the first surface 41 of the second circuit board 40. For example, the first electrical connector 33 and the second electrical connector 43 can be a socket electrical connector and a plug electrical connector respectively, and the first electrical connector 33 and the second electrical connector 43 are connected to each other correspondingly, so that the first circuit board 30 and the second circuit board 40 are electrically connected to each other, and the first circuit board 30 and the second circuit board 40 can further maintain a distance between each other by limiting the first electrical connector 33 and the second electrical connector 43 to avoid touching or squeezing each other.

[0073] like Figures 1 to 5 As shown in the figure, in this embodiment, the camera device 1 includes two stepped screws 50A and 50B, but this is not limited to the present invention. The camera device 1 may also include only one stepped screw 50A. The stepped screw 50A may be an integrally formed structure and include a head 51A, a connecting column 52A and a stud 53A. The connecting column 52A is connected between the head 51A and the stud 53A. Specifically, Figure 5 As shown, the connecting column 52A has a first end 521A and a second end 522A opposite to each other, the first end 521A is connected to the head 51A, the second end 522A is connected to the stud 53A, and the diameter of the head 51A is larger than the diameter of the connecting column 52A, and the diameter of the connecting column 52A is larger than the diameter of the stud 53A.

[0074] like Figure 3 and Figure 5 As shown, during the assembly process of the camera device 1, the stepped screw 50A can be inserted from the second surface 42 of the second circuit board 40 into the second through hole 45 of the second circuit board 40 and the first through hole 35 of the first circuit board 30, wherein the diameter of the stud 53A of the stepped screw 50A is smaller than the aperture of the first through hole 35, and the stud 53A passes through the first through hole 35 and is locked to the inner side 13 of the outer cover 10. The diameter of the connecting post 52A is larger than the aperture of the first through hole 35 and smaller than the aperture of the second through hole 45, the connecting post 52A passes through the second through hole 45, and the second end 522A of the connecting post 52A abuts against the outer surface 32 of the first circuit board 30, so that the first circuit board 30 can be fixed to the inner side 13 of the outer cover 10, so as to prevent the photosensitive component 34 on the first circuit board 30 from shifting and affecting the image sensing quality.

[0075] Figure 6 for Figure 5 A partial enlarged view of area 6. Figure 5 and Figure 6As shown, the circumference of the connecting column 52A of the stepped screw 50A further has a first movable gap G1 with the hole edge 451 of the second through hole 45. The diameter of the head 51A of the stepped screw 50A is larger than the aperture of the second through hole 45, and there is a second movable gap G2 between the head 51A and the second surface 42 of the second circuit board 40, wherein the first movable gap G1 may be equal to, larger than, or smaller than the second movable gap G2. In this way, the second circuit board 40 may be limited by the stepped screw 50A but not positioned, that is, by having the first movable gap G1 and the second movable gap G2 between the stepped screw 50A and the second circuit board 40, the second circuit board 40 is not positioned but still has room for movement, thereby being able to absorb the internal stress or external force generated by various conditions after the camera device 1 is assembled, thereby avoiding the camera device 1 from being damaged due to force.

[0076] To be specific, Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the stepped screw 50A and the first electrical connector 33 are respectively adjacent to two opposite sides of the first circuit board 30. When the camera device 1 is assembled, if the first circuit board 30 and the second circuit board 40 generate internal stress after being assembled due to the manufacturing tolerance of the assembled parts, the assembly tolerance during assembly, or the deviation of the assembly position, the second circuit board 40 can move in multiple axial directions (for example, toward the first movable gap G1 and the second movable gap G2) in response to the internal stress. Figure 2 The second circuit board 40 can be movable in the X-axis direction, Y-axis direction or Z-axis direction of the camera 1, for example, the second circuit board 40 can swing with the first electrical connector 33 as a fulcrum, thereby eliminating the internal stress and preventing the camera device 1 from being damaged by the force. Alternatively, when the camera device 1 is subjected to an external force (such as an external force generated by a fall or vibration), the second circuit board 40 can also move in multiple axial directions in response to the external force based on the first movable gap G1 and the second movable gap G2, thereby eliminating the external force and preventing the camera device 1 from being damaged by the force.

[0077] like Figure 3 and Figure 5 As shown, the structure of another stepped screw 50B may be the same as or similar to the structure of the stepped screw 50A and also include a head 51B, a connecting column 52B and a stud 53B, wherein the connecting column 52B is connected between the head 51B and the stud 53B. Specifically, the connecting column 52B has a third end 521B and a fourth end 522B opposite to each other, wherein the third end 521B is connected to the head 51B, and the fourth end 522B is connected to the stud 53B, and the diameter of the head 51B is greater than the diameter of the connecting column 52B, and the diameter of the connecting column 52B is greater than the diameter of the stud 53B.

[0078] like Figure 3 and Figure 5 As shown, the first circuit board 30 further includes a third through hole 36, the third through hole 36 passes through the inner surface 31 and the outer surface 32, and the third through hole 36 and the first through hole 35 are respectively located at different positions of the first circuit board 30. The second circuit board 40 includes a fourth through hole 46, the fourth through hole 46 passes through the first surface 41 and the second surface 42 and corresponds to the third through hole 36, and the fourth through hole 46 has a hole edge 461. During the assembly process of the camera device 1, the stepped screw 50B can be inserted from the second surface 42 of the second circuit board 40 into the fourth through hole 46 and the third through hole 36 of the first circuit board 30, wherein the diameter of the stud 53B of the stepped screw 50B is smaller than the hole diameter of the third through hole 36, and the stud 53B passes through the third through hole 36 and is locked to the inner side 13 of the outer cover 10. The diameter of the connecting column 52B is larger than the aperture of the third through hole 36 and smaller than the aperture of the fourth through hole 46. The connecting column 52B passes through the fourth through hole 46, and the fourth end 522B of the connecting column 52B abuts against the outer surface 32 of the first circuit board 30, so that the first circuit board 30 can be more firmly assembled to the inner side 13 of the outer cover 10.

[0079] like Figure 5 As shown, there is a third movable gap (such as the first movable gap G1) between the circumference of the connecting column 52B of the step screw 50B and the hole edge 461 of the fourth through hole 46. The diameter of the head 51B of the step screw 50B is larger than the hole diameter of the fourth through hole 46, and there is a fourth movable gap (such as the second movable gap G2) between the head 51B and the second surface 42 of the second circuit board 40. Therefore, the second circuit board 40 can obtain a better limiting effect through the step screw 50A and the step screw 50B, and based on the first movable gap G1, the second movable gap G2, the third movable gap and the fourth movable gap, the second circuit board 40 is not positioned and still has room for movement, so that it can absorb the internal stress or external force generated after the camera device 1 is assembled, and avoid the camera device 1 from being damaged due to the force.

[0080] like Figure 2 , Figure 3 and Figure 5 As shown, the first circuit board 30 includes four corner areas 37, and the step screw 50A and the other step screw 50B can be respectively adjacent to two of the four corner areas 37 to enhance the limiting effect of the second circuit board 40 and the positioning effect of the first circuit board 30. In this embodiment, the step screw 50B and the first electrical connector 33 are adjacent to the same side of the first circuit board 30, and the step screw 50A and the step screw 50B are respectively adjacent to two opposite sides of the first circuit board 30.

[0081] In some embodiments, the camera device 1 may include multiple lens bushings, and the same outer cover 10 may selectively assemble one of the multiple lens bushings to match different lenses or change the assembly position of the original lens. Specifically, since the focus height, appearance size or fixing method of lenses of different brands or styles are different, the lens bushing is used as a connecting bridge between the outer cover 10 and the lens, so that different lens bushings can be replaced to match lenses of different brands or styles, so that the structure of the outer cover 10 can share lenses of different brands or styles without changing or redesigning, thereby achieving the advantages of reducing the range of changes, optimizing development time and reducing costs, etc., which are respectively explained in the following figures.

[0082] Please check Figure 7 and Figure 8 As shown, Figure 7 for Figure 4 The cross-sectional view along line segment 7-7, Figure 8 The cross-sectional view of another lens bushing installed on the camera device of the present invention. In this embodiment, the camera device 1 may include another lens bushing 60A, and the lens bushing 60 or the lens bushing 60A may be selectively assembled on the assembly portion 15, and the shape of the lens bushing 60 is different from the shape of the lens bushing 60A (for example, the length, width, thickness, appearance or assembly structure of the lens bushing 60 and the lens bushing 60A are different), and the lens 20 is assembled on the lens bushing 60 or the lens bushing 60A.

[0083] That is to say, Figure 7 As shown, the assembly portion 15 of the outer cover 10 can be assembled with the lens sleeve 60, and the lens 20 is then assembled on the lens sleeve 60. Alternatively, as Figure 8 As shown, the assembly portion 15 of the outer cover 10 can also be replaced with another different lens bushing 60A. Here, the lens bushing 60A is also screwed and assembled to the multiple locking holes 151 of the assembly portion 15 by multiple screws 70 (please refer to Figure 2 As shown in FIG. 1 , the lens 20 is assembled to another lens bushing 60A. For example, the lens 20 can be assembled and fixed to the lens bushing 60A by bonding, snapping, screwing or welding. Therefore, the position of the lens 20 can be adjusted by replacing different bushings in the embodiment of the present invention. For example, please refer to FIG. Figure 7 and Figure 8 As shown, the overall thickness D1 of the lens bushing 60 may be different from the overall thickness D2 of another lens bushing 60A (here the thickness D1 is smaller than the thickness D2), so that the camera device 1 can replace and assemble lens bushings 60, 60A of different thicknesses with the same assembly portion 15 of the same outer cover 10 to adjust the assembly position of the lens 20 (for example, adjust the distance between the lens 20 and the photosensitive component 34).

[0084] Fig. 9This is a cross-sectional view of another lens bushing and lens installed in the camera device of the present invention. Please refer to Figure 7 and Fig. 9 As shown, in this embodiment, the camera device 1 may include another lens bushing 60B and another lens 20B, and the lens 20B may be assembled on the lens bushing 60B. The lens bushing 60 or the lens bushing 60B may be selectively assembled on the assembly portion 15, and the lens 20 is different from the lens 20B. For example, the lens 20 and the lens 20B are respectively a standard lens and a wide-angle lens, or the assembly structure of the lens 20 is different from the assembly structure of the lens 20B. That is, the assembly portion 15 of the outer cover 10 can be assembled with the lens bushing 60 or the lens bushing 60B to respectively provide different types of lenses for installation, for example Figure 7 As shown, the assembly portion 15 of the outer cover 10 can be assembled with the lens bushing 60, and the lens 20 is assembled on the lens bushing 60 by adhesive, or, as shown in FIG. Fig. 9 As shown, the assembly portion 15 of the outer cover 10 can also be replaced with another different lens bushing 60B. Here, the lens bushing 60B is also screwed and assembled to the multiple locking holes 151 of the assembly portion 15 by multiple screws 70 (please refer to Figure 2 As shown), the difference between the lens bushing 60B and the lens bushing 60 is at least that the lens bushing 60B has an internal threaded hole 61, and the lens 20B has an external threaded portion 21 to be fixed to the internal threaded hole 61 of the lens bushing 60B with a corresponding screw lock.

[0085] Fig.10 This is a cross-sectional view of another lens bushing installed in the camera device of the present invention. Figure 2 , Figure 7 and Fig.10 As shown, in this embodiment, in addition to the assembly portion 15, the outer side 12 of the outer cover 10 further has another assembly portion 16, and the outer cover 10 can selectively assemble the lens bushing 60 with the assembly portion 15 or assemble another lens bushing 60C with the assembly portion 16, wherein the shape of the lens bushing 60 is different from the shape of the lens bushing 60C (for example, the length, width, thickness, appearance or assembly structure of the lens bushing 60 and the lens bushing 60C are different), and the lens 20 is assembled to the lens bushing 60 or the lens bushing 60C. That is, Figure 7 As shown, the assembly portion 15 of the outer cover 10 can be assembled with the lens bushing 60, and the lens 20 is assembled on the lens bushing 60, or, as shown in FIG. Fig.10As shown, the assembling portion 16 of the outer cover 10 can also be replaced to assemble another different lens bushing 60C. Here, the assembling portion 16 of the outer side 12 of the outer cover 10 is an adhesive portion, wherein the adhesive portion can be an annular groove for filling with liquid adhesive H1. The difference between the lens bushing 60C and the lens bushing 60 lies in the different assembly structures, wherein the lens bushing 60C has an outer ring 62, and the outer ring 62 is correspondingly placed in the assembling portion 16 and then fixed to the outer cover 10 through the adhesive H1. The lens 20 can be assembled and fixed to the lens bushing 60C by adhesion, snap-fit, screw lock or welding.

[0086] Fig.11 A cross-sectional view of another lens bushing and a lens installed in the camera device of the present invention is shown in FIG.
