Description

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 obtain external images. For example, a camera device can be installed on a vehicle to obtain external images for driving assistance.

[0003] As most products are currently developing towards a trend of being lighter and thinner, 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 plurality of circuit boards stacked on top of each other. However, during the assembly or use of the camera device, the plurality of circuit boards are easily displaced by force and touch or squeeze each other, resulting in damage to the circuit boards. 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 and a second circuit board. The outer cover includes a first end and a second end axially opposite to each other, an axial hole and a limiting column, and the limiting column extends integrally from the second end. The lens is disposed at the first end of the outer cover. The first circuit board is fixed to the second end of the outer cover, and the first circuit board includes an inner surface and an outer surface opposite to each other, and a photosensitive element is disposed on the inner surface, and the photosensitive element is located in the axial hole and corresponds to the lens. The first circuit board is also provided with an avoidance area, and the avoidance area passes through the inner surface and the outer surface and corresponds to the limiting column. The second circuit board is electrically connected to the first circuit board, and the second circuit board includes a first surface and a second surface opposite to each other, and the first surface faces the outer surface of the first circuit board. The limiting column of the outer cover passes through the avoidance area of ​​the first circuit board and extends to the first surface of the second circuit board, so that the first circuit board and the second circuit board maintain a fixed distance.

[0005] In summary, according to the camera device of the embodiment of the present invention, the limiting post of the outer cover passes through the avoidance area of ​​the first circuit board and extends to the first surface of the second circuit board, so that the first circuit board and the second circuit board can maintain a fixed distance, thereby preventing the first circuit board and the second circuit board from touching or squeezing each other and being damaged. In addition, by extending the limiting post from the outer cover as a whole, it is possible to achieve the goal of not needing to provide additional limiting elements, thereby reducing costs and improving assembly efficiency.

[0040] 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 to be protected. In addition, some elements 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 elements in all drawings.

[0041] 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 is a partially exploded perspective view of an embodiment of a camera device of the present invention, Figure 4 for Figure 1 The cross-sectional view along line segment 4-4. Figure 1 to Figure 2 As shown, in this embodiment, the camera device 1 includes an outer cover 10, a lens 20, a first circuit board 30, and a second circuit board 40. In some embodiments, the camera device 1 can be applied to various electronic products to obtain 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 image systems), mobile devices (such as smart phones, tablet computers, or laptop computers), or cameras.

[0042] like Figures 1 to 4 As shown, the outer cover 10 includes a first end 11 and a second end 12 axially opposite to each other, an axial hole 13 and a limiting column 14a. In this embodiment, the axial hole 13 passes through the first end 11 and the second end 12 of the outer cover 10, so that the outer cover 10 is annular and hollow, wherein the shape of the axial hole 13 can be a circular hole, an elliptical hole, a square hole or other irregular holes, which is not limited.

[0043] like Figure 3 and Figure 4 As shown, the limiting post 14a integrally extends from the second end 12 of the outer cover 10. For example, the outer cover 10 is an integrally formed structure. For example, the outer cover 10 can be made of metal or plastic and can be integrally manufactured by injection molding or machining. In this embodiment, the limiting post 14a is a columnar body and extends in a direction away from the first end 11, and the limiting post 14a protrudes from the second end 12 of the outer cover 10.

[0044] like Figures 2 to 4 As shown, in the present embodiment, the second end 12 of the outer cover 10 further has an inner ring 121 and an outer ring 122, and the limiting column 14a of the outer cover 10 is integrally extended from the inner ring 121, but this is not limited to this. In some embodiments, the limiting column 14a may also be integrally extended from other positions of the second end 12 of the outer cover 10. For example, the limiting column 14a may be integrally extended from a local area of ​​the edge of the axial hole 13.

[0045] like Figures 2 to 4 As shown, the lens 20 is disposed at the first end 11 of the outer cover 10 to cover one end of the shaft hole 13. The lens 20 can be fixed to the first end 11 of the outer cover 10 by other means such as adhesion, buckle, screw lock or welding.

[0046] like Figures 1 to 3 As shown, the first circuit board 30 is fixed to the second end 12 of the outer cover 10 and covers the end of the shaft hole 13 away from the lens 20. The first circuit board 30 includes an inner surface 31 and an outer surface 35 opposite to each other, wherein the inner surface 31 is the surface of the first circuit board 30 facing the inner side of the outer cover 10, and a photosensitive element 311 is provided on the inner surface 31, and the photosensitive element 311 is located in the shaft hole 13 and corresponds to the lens 20, so that the external light can pass through the shaft hole 13 and focus on the photosensitive element 311 after entering from the lens 20, so that the photosensitive element 311 can sense and obtain an image. In some embodiments, the first circuit board 30 may be provided with conductive circuits and electronic components (such as a microprocessor, a resistor or a capacitor, etc.), which are omitted here.

[0047] In some embodiments, the photosensitive element 311 may be a charge-coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), or a complementary metal-oxide semiconductor active pixel sensor (CMOS active pixel sensor).

[0048] In some embodiments, the first circuit board 30 can be fixed to the second end 12 of the outer cover 10 by locking, adhering or snapping. Figures 2 to 4 As shown, in this embodiment, the first circuit board 30 includes a first assembling portion 33 and a second assembling portion 34. The first circuit board 30 is fixed to the second end 12 of the outer cover 10 via the first assembling portion 33 and the second assembling portion 34. Here, the first assembling portion 33 and the second assembling portion 34 are through holes or threaded holes for two screws S2 to pass through and be locked to the second end 12 of the outer cover 10, so that the first circuit board 30 and the outer cover 10 are fixed to each other.

[0049] like Figures 2 to 4As shown, the first circuit board 30 is also provided with an avoidance area 32a, which is a groove or a hole, and the avoidance area 32a passes through the inner surface 31 and the outer surface 35 and corresponds to the limiting column 14a of the outer cover 10, so that after the first circuit board 30 is fixed to the second end 12 of the outer cover 10, the limiting column 14a can penetrate into the avoidance area 32a.

[0050] like Figures 2 to 4 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 first surface 41 and a second surface 45 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 35 of the first circuit board 30. In some embodiments, the second circuit board 40 may also be provided with conductive circuits and electronic components (such as microprocessors, resistors or capacitors, etc.), which are omitted here.

[0051] like Figures 2 to 4 As shown, in the present embodiment, the limiting post 14a of the outer cover 10 passes through the avoidance area 32a of the first circuit board 30 and protrudes from the outer surface 35 of the first circuit board 30, and the end of the limiting post 14a also extends to the first surface 41 of the second circuit board 40. For example, the end of the limiting post 14a can directly contact the first surface 41 or be very close to the first surface 41 (for example, there is a slight tolerance gap between the end of the limiting post 14a and the first surface 41).

[0052] Thus, during the assembly or use of the camera device 1, the second circuit board 40 can be limited by the limiting column 14a and maintain a fixed distance D with the first circuit board 30, so as to prevent the first circuit board 30 and the second circuit board 40 from being touched or squeezed by external force, thereby preventing the circuits or electronic components of the first circuit board 30 and the second circuit board 40 from being damaged. In addition, since the limiting column 14a is integrally extended from the outer cover 10, it is not necessary to add other limiting elements, thereby reducing costs and improving assembly efficiency. In other words, the limiting column 14a can be integrally formed after the outer cover 10 is manufactured, so it is not necessary to manufacture another limiting element separately, thereby reducing manufacturing costs. After the outer cover 10 is assembled, the circuit board can be limited, and it is not necessary to install other limiting elements, thereby reducing assembly time and improving assembly efficiency.

[0053] For example Figures 2 to 4As shown, in the present embodiment, the first circuit board 30 and the second circuit board 40 are electrically connected to each other through an electrical connector. Here, a first electrical connector 36 is provided on the outer surface 35 of the first circuit board 30, and a second electrical connector 42 is provided on the first surface 41 of the second circuit board 40. For example, the first electrical connector 36 and the second electrical connector 42 can be a socket electrical connector and a plug electrical connector respectively, and the first electrical connector 36 and the second electrical connector 42 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 avoid touching or squeezing each other by limiting the first electrical connector 36 and the second electrical connector 42.

[0054] For example Figure 3 and Figure 4 As shown, the avoidance area 32a and the first electrical connector 36 provided on the first circuit board 30 are respectively adjacent to the opposite sides of the first circuit board 30 to enhance the limiting effect. For example, in the present embodiment, the first circuit board 30 includes a first side 301 and a second side 302 opposite to each other, the avoidance area 32a and the limiting column 14a are adjacent to the first side 301, and the first electrical connector 36 is adjacent to the second side 302, so that the opposite sides of the second circuit board 40 can be respectively limited by the limiting column 14a and the first electrical connector 36 to ensure that the second circuit board 40 will not be forced to approach the first circuit board 30, thereby avoiding the first circuit board 30 and the second circuit board 40 from touching or squeezing each other.

[0055] like Figure 3 As shown, the first assembly portion 33 and the second assembly portion 34 of the first circuit board 30 are also adjacent to the opposite sides of the first circuit board 30, respectively. For example, in this embodiment, the first assembly portion 33 is adjacent to the first side 301, and the second assembly portion 34 is adjacent to the second side 302, so that the opposite sides of the first circuit board 30 can be fixed and made more stable, thereby preventing the first circuit board 30 from being displaced due to force.

[0056] More preferably, the first assembly portion 33, the second assembly portion 34 and the avoidance area 32a may be located at three of the four corner areas 37a, 37b, 37c and 37d of the first circuit board 30, respectively. Figure 3As shown, here, the first assembly portion 33 and the avoidance area 32a are located at two corner areas 37a and 37b of the first circuit board 30 close to the first side 301, the second assembly portion 34 is located at the diagonal of the first assembly portion 33 and at one corner area 37c of the first circuit board 30 close to the second side 302, and the partial area of ​​the first electrical connector 36 extends to another corner area 37d of the first circuit board 30 close to the second side 302. In this way, the two corner areas 37a and 37c of the first circuit board 30 located at the diagonal can be fixed to the outer cover 10 to obtain a stable positioning effect, and the other two corner areas 37b and 37d located at the diagonal can limit the second circuit board 40 through the limiting pillar 14a and the first electrical connector 36 to prevent the first circuit board 30 and the second circuit board 40 from touching or squeezing each other.

[0057] Figure 5 is a partially exploded perspective view of another embodiment of the camera device of the present invention, Figure 6 FIG. 2 is a cross-sectional view of another embodiment of the camera device of the present invention. Figure 5 and Figure 6 As shown, this embodiment is different from the above Figure 3 and Figure 4 The difference between the embodiment of the present invention is at least that the first circuit board 30 and the second circuit board 40 of the present embodiment are electrically connected to each other through a flexible circuit 60, for example, the flexible circuit 60 may be a flexible printed circuit, and the outer cover 10 further includes another limiting column 14b, the first circuit board 30 is provided with another avoidance area 32b corresponding to the other limiting column 14b, the other limiting column 14b passes through the other avoidance area 32b and extends to the first surface 41 of the second circuit board 40, so that the second circuit board 40 can be limited by the two limiting columns 14a and 14b at the same time to obtain a better limiting effect, so that the first circuit board 30 and the second circuit board 40 are kept at a fixed distance D through the two limiting columns 14a and 14b. In some embodiments, the number of limiting columns of the outer cover 10 and the number of avoidance areas of the first circuit board 30 may also be more than three, which is not limited.

[0058] For example Figure 5 and Figure 6 As shown, the avoidance area 32a and the other avoidance area 32b provided on the first circuit board 30 are respectively adjacent to the opposite sides of the first circuit board 30 to enhance the limiting effect. For example, in the present embodiment, the avoidance area 32a and the limiting column 14a are adjacent to the first side 301, and the avoidance area 32b and the limiting column 14b are adjacent to the second side 302, so that the opposite sides of the second circuit board 40 can be limited by the limiting column 14a and the other limiting column 14b respectively, so as to ensure that the second circuit board 40 will not be forced to approach the first circuit board 30, thereby avoiding the first circuit board 30 and the second circuit board 40 from touching or squeezing each other.

[0059] Preferably, the first assembly portion 33, the second assembly portion 34, the avoidance area 32a and the other avoidance area 32b can be located at the four corner areas 37a, 37b, 37c and 37d of the first circuit board 30 respectively. Figure 5 and Figure 6 As shown, here, the first assembly portion 33 and the avoidance area 32a are located at two corner areas 37a and 37b of the first circuit board 30 close to the first side 301, the second assembly portion 34 is located at the diagonal of the first assembly portion 33 and at one corner area 37c of the first circuit board 30 close to the second side 302, and the other avoidance area 32b is located at another corner area 37d close to the second side 302. In this way, the two corner areas 37a and 37c of the first circuit board 30 located at the diagonal can be fixed to the outer cover 10 to obtain a stable positioning effect, and the other two corner areas 37b and 37d located at the diagonal can limit the second circuit board 40 through the limiting column 14a and the other limiting column 14b to prevent the first circuit board 30 and the second circuit board 40 from touching or squeezing each other.
