Description

Technical Field

[0001] The present invention relates to at least a dual-purpose camera device, and in particular to a dual-purpose camera device in which a lens module can be conveniently rotated around the optical axis of a lens barrel and which also has high stability and high reliability. Background Art

[0002] With the popularization of motor vehicles such as cars and artificial intelligence, it is necessary to equip the interior of the motor vehicle with an ADAS (Advanced Driver Assistance System) camera device, which includes a monocular ADAS camera or a binocular ADAS camera.

[0003] In recent years, monocular ADAS camera devices inside motor vehicles have gradually been replaced by binocular ADAS camera devices; the main reason is that binocular cameras not only have all the functions of monocular cameras, but can also recognize depth information; however, binocular camera devices have particularly strict requirements on the distance tolerance between the two lenses.

[0004] Conventional binocular camera devices for motor vehicles are shown in the attached manual. Figures 1 to 3 As shown. Figure 1 As shown, a conventional binocular camera device generally includes a front housing 1, a rear housing 2 and two camera modules 3. These components are assembled, for example, by screws 21 to form a Figure 3 The binocular camera device shown in FIG. Figure 2 As shown, the camera module 3 generally includes a lens 22, a lens holder 23 and a printed circuit board assembly (PCBA). The PCBA generally includes an integrated optical sensor 14 and a printed circuit board 11. The optical sensor 14 can receive an optical signal from the lens 22, and convert the optical signal into an electrical signal, and transmit the converted electrical signal to the printed circuit board 11. The optical sensor 14 is integrated with the printed circuit board 11 to form a PCBA as a hard board. During the assembly process, the lens 22 is mounted on the lens holder 23, and the lens holder 23 is then fixed to the PCBA hard board by screws 21 or the like to form a single camera module 3. Finally, two single camera modules 3 can be fixed to the front shell 1 or the rear shell 2 by means of the PCBA hard board by screws 21 or other various methods known in the art.

[0005] In the above-mentioned traditional camera device, the lens assembly of the lens 22 and the lens holder 23 is located in front of the PCBA hard board as a whole, so the center of gravity of the assembly must be located in front of the PCBA hard board. This causes the lens assembly to vibrate continuously as the car bumps during the operation of the car. The farther the center of gravity of the assembly is from the PCBA hard board, the more violent the vibration. This vibration may loosen the connection between the lens assembly and the PCBA hard board, the connection between the PCBA hard board and the front shell 1 or the rear shell 2, and / or the connection between the lens 22 and the lens holder 23, thereby further causing the lens 22 to vibrate more violently relative to the car body as the car bumps during operation. This leads to serious insufficiency in stability and reliability of the traditional camera device.

[0006] In addition, the method of fixing the two single camera modules 3 adopted by the conventional binocular camera device requires that the installation angles of the two sensors in the two modules must match each other before installation. Once the installation angles deviate due to the fixing device such as screws or due to the vibration as described above, it is difficult to adjust the installation angles to match each other.

[0007] In addition, the structural dimension chain used in traditional binocular camera devices is relatively long, and the consistency of the distance between lenses is difficult to control; the algorithm needs to perform more calculations to meet its design requirements. Summary of the invention

[0008] Problems to be solved by the present invention

[0009] The object of the present invention is to provide a camera device with at least two eyes having high stability and high reliability and a lens module that can be easily rotated around the optical axis of the lens barrel, which can overcome or at least reduce the inherent disadvantages of the prior art binocular camera device as described in the above background technology section. That is, the present invention is to provide a camera device with at least two eyes, the vibration of which lens relative to the body of the motor vehicle should be relatively small, and in addition, before the assembly of the camera device with at least two eyes is completed, each of the at least two lens modules can be rotated around the optical axis of the lens barrel, so that the installation angles of the two sensors in the two lens modules can be easily adjusted to match each other.

[0075] Furthermore, the at least two-eye camera device provided by the present invention preferably has an adjustment mechanism in the lens module, and before assembly is completed, at least two lens modules can be easily rotated around the optical axis of the lens barrel, so that the installation angles of the two sensors in the two lens modules can be easily adjusted, and then the imaging angles thereof can be controlled to match each other. During the adjustment process, the circuit board is not subjected to stress, but the lens adjustment mechanism is subjected to stress; therefore, the circuit board will not be deformed, and the glue will not be cracked under stress; while meeting the functional requirements, the reliability of the module itself will not be affected.

In addition, in the at least dual-purpose camera device provided by the present invention, a flexible connection such as a flexible flat cable is preferably used between the sensor board and the printed circuit board; the tolerance generated during assembly and adjustment can be effectively absorbed.

[0077] In addition, at least the binocular camera device of the present invention can be applied to various types of modules (multi-view, surround view, rear view, side view, in-cabin view, etc.), and has strong versatility.

[0078] In fact, at least the binocular camera device of the present invention can have a combination of the above advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0128] Technologies, methods, and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0129] In the following, reference will be made to the Figures 4 to 20The technical solution of the present invention is further specifically described.

[0130] Specifically, the present invention relates to a camera device with at least two purposes, which comprises at least two lens modules 3, a front shell 1 and a rear shell 2, wherein the front shell 1 has a through hole 6, and the rear shell 2 is connected to the front shell 1 to form a cavity between the front shell 1 and the rear shell 2, wherein:

[0131] The lens module 3 includes a lens module 15, a sensor board 10 and a printed circuit board 11, and

[0132] The camera device further comprises a fastening mechanism,

[0133] in,

[0134] The printed circuit board 11 is located inside the cavity;

[0135] The lens module 15 includes a lens barrel 7, the lens barrel 7 has a barrel front end and a barrel rear end, the lens barrel 7 passes through the through hole 6 so that the barrel front end is located outside the cavity, and the barrel rear end is located inside the cavity;

[0136] The sensor board 10 is located inside the cavity and fixedly connected to the lens barrel 7 so that light passing through the lens barrel 7 can reach the sensor 14 on the sensor board 10, and the sensor board 10 is also connected to the printed circuit board 11; and

[0137] The fastening mechanism is used to fix the lens module 15 to the front housing 1 , and the fastening structure also allows the lens module 15 to rotate around the optical axis of the lens barrel 7 before being fixed to the front housing 1 .

[0138] Those skilled in the art will appreciate that, in the at least dual-purpose camera device as described above, the form of the front shell 1 and the rear shell 2 and their connection method are not particularly limited, as long as the front shell 1 and the rear shell 2 are fixedly connected together in cooperation with each other to form a cavity between them. Here, the term "cavity" means a closed space, and the boundary of the closed space should be understood to include: the outer surface of the front shell 1 and the rear shell 2; and the surface defined by the boundary formed by the outer surface of the front shell 1 and the rear shell 2 and the side walls of any holes, channels or gaps present on the front shell 1 and the rear shell 2. The space can communicate with the outside world through holes, channels or gaps of any shape and size located on the front shell 1 and / or the rear shell 2. Those skilled in the art may consider fixing the front shell 1 and the rear shell 2 together in cooperation with each other through various methods such as integral molding, casting, welding, adhesive bonding, screw fixing, rivet fixing and / or bayonet fixing. In fact, in the present invention, the front shell 1 and the rear shell 2 can even be understood as the first fixing bracket and the second fixing bracket that play their respective roles, and there may be another shell outside the bracket. In addition, there is no clear boundary between the front shell 1 and the rear shell 2. When they are regarded as an integral shell (for example, when they are integrally formed), the front shell 1 and the rear shell 2 can be regarded as the relatively front part and the relatively rear part of the integral shell.

[0139] In the at least dual-purpose camera device as described above, the front shell 1 and / or the rear shell 2 may further have another through hole in addition to the defined through hole 6, and the other through hole may be used for multiple purposes such as connection between the printed circuit board 11 and the outside and signal transmission (such as Figure 4 In addition, the camera device can be fixedly mounted on a motor vehicle such as a car by means of additional through holes on the front shell 1 and / or the rear shell 2 and / or additional devices known to those skilled in the art on the outer surface of the front shell 1 and / or the rear shell 2. For example, the additional devices can be Figure 1 , 3 Or the protrusions shown in 8 located on opposite sides of the front shell 1.

[0140] In the at least binocular camera device as described above, the lens barrel 7 of the lens module 15 is optionally used to accommodate lenses. The manner in which the sensor board 10 is fixedly connected to the lens barrel 7 is not particularly limited, as long as the manner enables the sensor board 10 to be fixedly connected to the lens barrel 7 and enables the light passing through the optional lens and the lens barrel 7 to reach the sensor 14 on the sensor board 10. Those skilled in the art may consider achieving this goal through a variety of methods such as integral molding, casting, welding, adhesive bonding, screw fixing, rivet fixing and / or bayonet fixing. For example, in a preferred at least binocular camera device of the present invention, as Figures 6 to 7 As shown, the lens barrel 7 is fixedly connected to the sensor plate 10 via an adhesive 13 .

[0141] In at least the binocular camera device as described above, the sensor 14 is a common optical sensor in the art, which can receive an optical signal from the lens barrel 7 and convert the optical signal into an electrical signal, and transmit the converted electrical signal to the printed circuit board 11.

[0142] In the at least binocular camera device as described above, there is no particular restriction on the connection method between the sensor board 10 and the printed circuit board 11. For example, it can be considered to be fixedly connected together by screws, rivets, welding, adhesives, casting, etc. It can even be considered to integrate the sensor 14 into the printed circuit board 11 to form a PCBA hard board to achieve the connection as described in the background technology section above. In this case, the sensor 14 and the printed circuit board 11 are integrated to obtain a PCBA hard board.

[0143] In the at least dual-purpose camera device as described above, preferably, the printed circuit board 11 is fixedly connected to the rear housing 2. In this case, the sensor board 10 is connected to the printed circuit board 11 by a flexible connection. For example, the sensor board 10 is preferably connected to the printed circuit board 11 by a flexible flat cable 12, such as Figures 5 to 7 In addition, it is also preferred that in this case, the sensor board 10 and / or the printed circuit board 11 and the soft board therebetween form a hard-soft board, thereby achieving a soft connection between the sensor board and the printed circuit board (this case is not shown in the drawings).

[0144] In the at least dual-purpose camera device as described above, preferably, the multiple sensor boards 10 of the at least two camera modules 15 can be connected not only to multiple printed circuit boards 11 (not shown in the drawings) by means of soft connection, but also to one printed circuit board 11 (such as Figure 5 shown in ).
