Description

Technical Field

[0001] This application relates to the field of cameras, and more particularly to a vehicle-mounted camera module and a vehicle. Background Technology

[0002] As a core perception component of autonomous driving systems, the performance requirements of automotive camera modules are continuously upgrading with technological advancements. Currently, automotive camera modules are prone to overexposure in strong light conditions and unclear imaging due to insufficient light intake in low light conditions, which is detrimental to driving safety. Utility Model Content

[0003] This application provides an in-vehicle camera module and a vehicle, which can improve the imaging quality of the in-vehicle camera module under strong light and low light conditions, enabling the driver to clearly observe road conditions and ensure driving safety.

[0004] In a first aspect, embodiments of this application provide an in-vehicle camera module, including a first housing, a second housing, a lens assembly, a circuit board, an image sensor, a variable aperture assembly, and a connector. The first housing and the second housing are connected, and a mounting cavity is formed between them. The first housing and the second housing can be collectively referred to as a housing. The lens assembly includes a lens barrel and a lens disposed within the lens barrel, and the lens assembly is mounted on the first housing. The image sensor is mounted on the circuit board, and both the circuit board and the image sensor are located within the second housing. The variable aperture assembly is mounted on the lens barrel and is used to control the amount of light incident on the image sensor. At least a portion of the connector is disposed within the second housing and electrically connected to the circuit board.

[0005] In this embodiment, a variable aperture component is incorporated into the lens barrel of the vehicle-mounted camera module. This component adjusts the aperture size according to changes in light intensity. For example, during the day or under strong light conditions, the aperture decreases to reduce light intake and prevent overexposure of the image. At night or under weak light conditions, the aperture increases to increase light intake and maintain overall image clarity. The images and video signals captured by the vehicle-mounted camera module can be transmitted to the vehicle's central control display or dashboard screen via a connector, allowing the driver to clearly observe real-time road conditions and ensure safe driving.

[0006] In one implementation of the first aspect, at least a portion of the variable aperture assembly is disposed on the object-side surface of the lens assembly; or, at least a portion of the variable aperture assembly is disposed on the image-side surface of the lens assembly. In this implementation, the aperture of the variable aperture assembly can be positioned either in front or behind the lens to meet corresponding product requirements.

[0007] In one implementation of the first aspect, the lens assembly includes at least two lenses, and at least a portion of the variable aperture assembly is located between any two adjacent lenses in the lens assembly. In this implementation, the aperture of the variable aperture assembly is centrally located, which is beneficial for correcting chromatic aberration, improving image quality, and also facilitates assembly, thus meeting the miniaturization requirements of automotive camera modules.

[0008] In one implementation of the first aspect, the variable aperture assembly includes a driving component and an aperture body, with the driving component electrically connected to the circuit board. In this implementation, the driving component is electrically connected to the circuit board, allowing it to share the circuit board with devices such as image sensors on the board, eliminating the need for an external power supply or signal source. This simplifies the circuit structure of the vehicle-mounted camera module and reduces production costs.

[0009] In one implementation of the first aspect, a conductive line is embedded within the first housing. One end of the conductive line is electrically connected to the driving component, and the other end is electrically connected to the circuit board. In this implementation, embedding the conductive line within the first housing simplifies the structure of the first housing, prevents short circuits caused by exposed conductive lines, and avoids friction between the conductive line and the inner wall of the first housing, thus preventing dust generation and contamination of the image sensor. This enhances the reliability of the vehicle-mounted camera module.

[0010] In one implementation of the first aspect, the lens barrel and the first housing are an integral structure; and / or, the connector and the second housing are an integral structure.

[0011] In this implementation, the lens barrel and the first housing can be a single integrated structure, meaning they are manufactured using an integral molding process. This integrated structure ensures effective support of the lens barrel by the first housing, reduces the overall number of components in the vehicle-mounted camera module, facilitates assembly and transportation, and helps lower production costs. Furthermore, this integrated structure improves the alignment accuracy of the first and second housings, resulting in better sealing and enhanced reliability and weather resistance of the vehicle-mounted camera module. Weather resistance refers to the ability of the vehicle-mounted camera module to maintain stable performance and reliability under complex natural environments and extreme working conditions, ensuring long-term normal operation under varying temperatures, humidity levels, vibrations, and corrosive conditions.

[0012] In this implementation, the connector and the second housing can be a single integrated structure, meaning they are manufactured using an integral molding process. This integrated structure ensures effective support of the connector by the second housing, reduces the overall number of components in the vehicle camera module, facilitates assembly and transportation, and helps lower production costs. Furthermore, this integrated structure improves the alignment accuracy between the first and second housings, resulting in better sealing and enhancing the reliability and weather resistance of the vehicle camera module.

[0013] In one implementation of the first aspect, the first housing and the lens barrel are fixedly connected by laser welding; and / or, the first housing and the second housing are fixedly connected by laser welding; and / or, the second housing and the connector are fixedly connected by laser welding. In this implementation, compared to traditional welding methods (such as arc welding, gas shielded welding, etc.), laser welding uses a high-energy-density laser beam as a heat source with an extremely small spot diameter, enabling high-precision welding. This improves alignment accuracy, connection reliability, and housing sealing. Furthermore, the heat from laser welding is highly concentrated and cools rapidly, which helps reduce thermal damage to the laser-welded components and surrounding devices, enhancing the long-term stability of the vehicle-mounted camera module.

[0014] In one implementation of the first aspect, the circuit board is fixed to the first housing by screw fastening; or, the circuit board is fixed to the second housing by screw fastening. In this implementation, the screw fastening technology is relatively mature, allowing the circuit board to be safely and reliably installed inside the housing.

[0015] In one implementation of the first aspect, the first housing is provided with mounting posts, and the circuit board is fixedly connected to the mounting posts by soldering or adhesive bonding. These two fixing methods are simple, convenient, and technologically mature, which helps to save production costs.

[0016] Secondly, this application provides a vehicle comprising a main body and any of the aforementioned vehicle-mounted camera modules, the vehicle-mounted camera module being disposed on the main body. In this embodiment, the vehicle using any of the aforementioned vehicle-mounted camera modules can maintain high imaging quality under different lighting conditions, which is beneficial for the driver to observe clear real-time road conditions and ensure the driver's driving safety.

[0036] This application provides a vehicle, including but not limited to sedans, sport utility vehicles (SUVs), and commercial vehicles, which can be electric vehicles or gasoline-powered vehicles.

[0037] Figure 1 This is a schematic diagram of the structure of vehicle 10 in one embodiment of this application. Figure 1 As shown, vehicle 10 may include headlights 11, windshield 12, roof 13, trunk lid 14, and an in-vehicle camera module. The in-vehicle camera module can be a front-view camera module, a rear-view camera module, a side-view camera module, or a side-rear-view camera module. In this embodiment, the components of vehicle 10 excluding the in-vehicle camera module can be collectively referred to as the main body, and the in-vehicle camera module is located within the main body. The in-vehicle camera module can be installed at any location on vehicle 10, such as the headlights 11, windshield 12, roof 13, or trunk lid 14.

[0038] Understandable Figure 1 The structure of the vehicle 10 and the location of the onboard camera module shown are merely illustrative examples and are not intended to limit the embodiments of this application.

[0039] Figure 2 This is an exploded view of the vehicle-mounted camera module 20 in one embodiment. Figure 3 for Figure 2 A schematic diagram of the AA cross-sectional structure of the vehicle-mounted camera module 20. Figure 4 for Figure 2 An exploded view of the vehicle-mounted camera module 20.

[0040] Combination Figure 2 and Figure 3 As shown, the vehicle-mounted camera module 20 may include a first housing 22, a second housing 23, a variable aperture assembly 27, a lens assembly 21, a circuit board 251, an image sensor 252, and a connector 24. The first housing 22 is connected to the second housing 23, and a mounting cavity 20a is formed between the first housing 22 and the second housing 23. The first housing 22 and the second housing 23 can be collectively referred to as a housing. The lens assembly 21 may include a lens barrel 211 and a lens 212 disposed within the lens barrel 211. The lens assembly 21 is mounted on the first housing 22, and the variable aperture assembly 27 is mounted on the lens barrel. The lens assembly 21 and the variable aperture assembly 27 can be collectively referred to as a lens. The image sensor 252 is mounted on the circuit board 251, and both the circuit board 251 and the image sensor 252 are mounted within the mounting cavity 20a. For example, circuit board 251 and image sensor 252 may both be located within the second housing 23, or circuit board 251 and image sensor 252 may both be located within the first housing 22, or image sensor 252 may be located within the first housing 22 and circuit board 251 may be located within the second housing 23. At least a portion of connector 24 is disposed within the second housing 23 and electrically connected to circuit board 251.

[0041] The structure of the lens assembly 21, the first housing 22, the second housing 23, the circuit board 251, the image sensor 252, the variable aperture assembly 27, and the connector 24 will be described in turn below.

[0042] like Figure 3 As shown, the lens assembly 21 may include a lens barrel 211 and lenses 212 within the lens barrel 211. The number of lenses 212 can be at least two, for example, five. The lenses 212 are used to collect ambient light and project it onto the image sensor 252. It is understood that... Figure 2 The structure, number, and position of the lens 212 shown are merely illustrative, and this embodiment does not impose specific limitations on them. In another embodiment, there may be only one lens 212.

[0043] like Figure 3 and Figure 4 As shown, the first housing 22 may have a light-transmitting hole 222. One end of the lens barrel 211 may be located inside the light-transmitting hole 222, and the other end of the lens barrel 211 may be located on the side of the light-transmitting hole 222 away from the second housing 23. The light-transmitting hole 222 is directly opposite the photosensitive surface of the image sensor 252, which refers to the side of the image sensor 252 facing the lens assembly 21.

[0044] like Figure 3 and Figure 4 As shown, the lens barrel 211 and the first housing 22 can be a single integrated structure, meaning that the lens barrel 211 and the first housing 22 are manufactured by integral molding. This integrated structure ensures effective support of the lens barrel 211 by the first housing 22, reduces the overall number of components in the vehicle-mounted camera module 20, facilitates assembly and transportation, and helps reduce production costs. Furthermore, this integrated structure improves the alignment accuracy of the first housing 22 and the second housing 23, resulting in better sealing of the housings and enhancing the reliability and weather resistance of the vehicle-mounted camera module 20, as will be explained below. The weather resistance of the vehicle-mounted camera module 20 refers to its ability to maintain stable performance and reliability under complex natural environments and extreme working conditions, ensuring long-term normal operation of the vehicle-mounted camera module in environments with varying temperatures, humidity, vibration, and corrosion.

[0045] It is understood that the lens barrel 211 and the first housing 22 are an integral structure, but this is only an illustrative example and is not limited in this embodiment. In another embodiment, the lens barrel 211 and the first housing 22 can also be separate structures, and the lens barrel 211 and the first housing 22 can be fixedly connected by, for example, laser welding, threaded connection or other feasible methods.

[0046] like Figure 3 and Figure 4 As shown, the end of the first housing 22 near the second housing 23 may have a mounting post 221. The mounting post 221 may be located within the through hole 251b of the circuit board 251, enhancing the reliability of the connection between the first housing 22 and the circuit board 251, as will be explained below. In another embodiment, the first housing 22 may not have a mounting post 221.

[0047] like Figure 3As shown, the first housing 22 and the second housing 23 can be fixedly connected by laser welding. The first housing 22 and the second housing 23 can be connected by an active alignment (AA) process. Compared with traditional welding methods (such as arc welding, gas shielded welding, etc.), laser welding is beneficial to improving the alignment accuracy of the first housing 22 and the second housing 23, improving the reliability of the connection between the first housing 22 and the second housing 23, enhancing the sealing performance of the housings, and also helping to reduce thermal damage to the first housing 22, the second housing 23 and their surrounding components, thereby enhancing the long-term stability of the vehicle-mounted camera module 20.

[0048] like Figure 4 As shown, circuit board 251 can be, for example, a printed circuit board (PCB). Circuit board 251 is used to receive and transmit signals from image sensor 252. A number of through holes 251b can be provided around the circuit board 251; for example, one through hole 251b can be provided at each of the four corners of the circuit board 251, for a total of four through holes 251b. The through holes 251b can be used to mate with the mounting posts 221 of the first housing 22. It is understood that... Figure 4 The shape, location, and number of through holes shown are merely illustrative examples and are not limited in this embodiment.

[0049] refer to Figure 3 and Figure 4 As shown, in another embodiment, the circuit board 251 may not have a through hole 251b, but instead has a recess corresponding to the mounting post 221. The cooperation between the mounting post 221 and the recess enhances the reliability of the connection between the first housing 22 and the circuit board 251.

[0050] Combination Figure 3 and Figure 4 As shown, in one embodiment, the circuit board 251 and the mounting post 221 of the first housing 22 can be fixedly connected by laser welding. For example, the circuit board 251 and the first housing 22 can be laser welded using an automated alignment process.

[0051] Combination Figure 3 and Figure 4 As shown, compared with traditional welding methods (such as arc welding, gas shielded welding, etc.), laser welding is beneficial to improve the alignment accuracy between the circuit board 251 and the first housing 22, improve the reliability of the connection between the circuit board 251 and the first housing 22, enhance the sealing of the housing, and also help reduce thermal damage to the circuit board 251, the first housing 22 and its surrounding components, and enhance the long-term stability of the vehicle camera module 20.

[0052] In another embodiment, the circuit board 251 can be fixedly connected to the mounting posts 221 of the first housing 22 by soldering with solder paste 28 or bonding with adhesive. These two fixing methods are simple and convenient, and the technology is mature, which helps to save production costs.

[0053] In another embodiment, the circuit board 251 can be fixed to the first housing 22 or the second housing 23 by screws. Screw fixing is a mature technology, allowing the circuit board 251 to be safely and reliably installed inside the housing.

[0054] like Figure 3 As shown, a connector 251a may be provided on the side of the circuit board 251 away from the lens assembly 21. The connector 251a can be used to connect with the connector 24, as will be described below. If necessary, in another embodiment, the circuit board 251 may not have the connector 251a, and the circuit board 251 can be directly electrically connected to the connector 24.

[0055] like Figure 3 and Figure 4 As shown, the image sensor 252 can be located between the circuit board 251 and the first housing 22, and is electrically connected to the circuit board 251. The image sensor 252 is used to receive light transmitted through the lens assembly 21 and generate an image.

[0056] like Figure 3 and Figure 4 As shown, circuit board 251 and image sensor 252 can be collectively referred to as circuit board module 25. Circuit board module 25 can be, for example, a printed circuit board assembly (PCBA). A printed circuit board module is an assembly that integrates the electronic components required by the camera module (such as image sensors, interface components, etc.) onto a printed circuit board through soldering, mounting, or other processes for the acquisition, processing, and transmission of image signals.

[0057] like Figure 3 and Figure 4 As shown, the variable aperture assembly 27 may include a drive assembly 271 and an aperture body 272, which are fixedly connected. The aperture body 272 may be fixed inside the lens barrel 211, and the drive assembly 271 may be located outside the lens barrel 211. The drive assembly 271 controls the size of the aperture opening of the aperture body 272 by energizing it, thereby controlling the amount of light incident on the image sensor 252.

[0058] It is understood that the aperture body 272 can be fixed inside the lens barrel 211. This is just an illustration. In fact, in this embodiment, as needed, for example when the aperture body 272 is located on the object side of the lens assembly 21, the aperture body 272 can be installed on the outside of the lens barrel 211.

[0059] It is understood that the drive component 271 is located outside the lens barrel 211. This is just an illustration. In fact, in this embodiment, the drive component 271 may also be partially or entirely located inside the lens barrel 211 as needed.

[0060] refer to Figure 3 and Figure 4 As shown, exemplarily, the drive assembly 271 may include a motor or other power device to meet the requirements, and may also include a transmission mechanism. The aperture body 272 may include multiple movable light-blocking blades. The variable aperture assembly 27 controls the amount of light entering by adjusting the aperture size. During the day or under other strong light conditions, the blades close to shrink the aperture, which can reduce the amount of light entering to avoid overexposure of image quality; at night or under other weak light conditions, the blades unfold to enlarge the aperture, which can increase the amount of light entering to maintain overall image clarity. The aperture size of the aperture body 272 can be divided into two or more stops, which is not limited in this embodiment.

[0061] Understandable Figure 3 and Figure 4 The structures of the driving component 271 and the aperture body 272 shown and described above are merely illustrative examples, and this embodiment does not impose any specific limitations on them.

[0062] like Figure 3 As shown, in one embodiment, the aperture body 272 can be located between any two adjacent lenses 212 of the lens assembly 21; this arrangement can be referred to as a centrally located aperture. A centrally located aperture design is beneficial for correcting chromatic aberration, improving image quality, and also facilitates assembly, thus meeting the miniaturization requirements of the vehicle-mounted camera module 20.

[0063] In another embodiment, the aperture body 272 can be located on the object-side surface of the lens assembly 21 (aperture front) or on the image-side surface of the lens assembly 21 (aperture rear), and the aperture front and aperture rear can meet the corresponding product requirements.

[0064] like Figure 3As shown, the drive component 271 can be electrically connected to the circuit board 251 and can share the circuit board 251 with devices such as the image sensor 252 on the circuit board 251, without the need for an external power supply or signal source, thereby simplifying the circuit structure of the vehicle camera module 20 and reducing production costs. For example, the connection between the variable aperture component 27 and the circuit board 251 can be made after the first housing 22 is aligned and connected to the circuit board 251, making the connection process more convenient and faster.

[0065] like Figure 3 As shown, a conductive line 26 is embedded within the first housing 22. One end of the conductive line is electrically connected to the drive assembly 271, and the other end is electrically connected to the circuit board 251. Embedding the conductive line 26 within the first housing 22 simplifies the structure of the first housing 22, prevents short circuits caused by exposed conductive lines 26, and avoids friction between the conductive line 26 and the inner wall of the first housing 22, thus preventing dust generation and contamination of the image sensor 252. This enhances the reliability of the vehicle-mounted camera module 20.

[0066] like Figure 3 As shown, one end of the conductive line 26 facing away from the drive assembly 271 can be fixed to the side of the circuit board 251 facing away from the first housing 22. This arrangement allows the conductive line 26 to avoid obstructing devices such as the image sensor 252 arranged on the circuit board 251, enabling the target surface size of the image sensor 252 to be designed to be larger, which is beneficial for improving the pixel count of the vehicle camera module 20. In addition, the conductive line 26 is connected to different sides of the image sensor 252 on the circuit board 251, which can avoid electromagnetic interference (EMI) from the image sensor 252. Electromagnetic interference refers to the phenomenon of performance degradation, malfunction, or signal distortion of electronic equipment, systems, or circuits caused by external or internal electromagnetic energy (such as electric fields, magnetic fields, or electromagnetic waves).

[0067] like Figure 3 As shown, for example, while one end of the conductive line 26 facing away from the drive assembly 271 is fixed to the side of the circuit board 251 facing away from the first housing 22, it can also be connected to the side wall of the circuit board 251 (e.g., by bonding with conductive adhesive), making the connection between the conductive line 26 and the circuit board 251 more reliable. In another embodiment, whether the conductive line 26 is connected to the side wall of the circuit board 251 can be set as needed.

[0068] Understandable Figure 3 The connection method between the variable aperture component 27 and the circuit board 251 shown and described above is only an illustrative example, and this embodiment does not limit it.

[0069] like Figure 3As shown, the type of conductive line 26 can be determined according to product requirements. For example, the conductive line 26 can be a flexible printed circuit (FPC) cable. FPC cables are ultra-thin and flexible, capable of being folded or rolled in three dimensions to adapt to the internal spatial layout of the vehicle camera module 20. FPC cables are lighter than conventional wires, helping to reduce the overall load on the vehicle camera module 20.

[0070] like Figure 3 As shown, connector 24 can be electrically connected to circuit board 251, for example, it can be plugged into connector 251a of circuit board 251. Connector 24 is used to electrically connect to the vehicle's central control system, which can transmit video signals collected by the vehicle camera module 20 to the central control display screen or instrument panel screen to clearly display images and ensure safe driving for the driver; it can also provide power and transmit signals to circuit board 251, enabling the variable aperture assembly 27 and other devices connected to circuit board 251 to operate normally. For example, connector 24 can be a Fakra connector (Fachkreis Automobil Connector), a high-performance radio frequency connector designed specifically for automotive electronic systems, which can provide power and transmit signals at high speed and stably.

[0071] like Figure 3 As shown, the connector 24 and the second housing 23 can be an integral structure. This integral structure ensures effective support of the connector 24 by the second housing 23, reduces the overall number of components in the vehicle camera module 20, facilitates assembly and transportation, and helps reduce production costs. Furthermore, this integral structure improves the alignment accuracy of the first housing 22 and the second housing 23, resulting in better sealing and enhancing the reliability and weather resistance of the vehicle camera module 20.

[0072] Understandable Figure 3 The connector 24 and the second housing 23 shown are an integral structure, which is only an illustrative example and is not limited in this embodiment. In another embodiment, the connector 24 and the second housing 23 can also be a separate structure, and the connector 24 and the second housing 23 can be fixedly connected by, for example, laser welding, threaded connection or other feasible methods.

[0073] The following is a brief description of one possible assembly method for the vehicle-mounted camera module 20.

[0074] like Figure 3As shown, the lens assembly 21 is installed inside the first housing 22, and at least a portion of the variable aperture assembly 27 is installed inside the lens barrel 211. The first housing 22 and the circuit board 251 can be automatically aligned and fixedly connected by laser welding. After the first housing 22 and the circuit board 251 are fixedly connected, the variable aperture assembly 27 can be connected to the circuit board 251 through a conductive line 26. The side of the conductive line 26 facing away from the first housing 22 can be fixed to the side of the circuit board module 25 facing away from the first housing 22. Finally, the first housing 22 and the second housing 23 can be automatically aligned and fixedly connected by laser welding. Since the lens barrel 211 and the first housing 22 are an integral structure, and the second housing 23 and the connector 24 are an integral structure, no additional assembly and fixing are required, making the structure of the vehicle camera module 20 simple and compact, with fewer assembly steps, reduced assembly costs, and high reliability after assembly.

[0075] Understandable Figure 3 The assembly methods shown and described above are merely illustrative and are not intended to limit the embodiments of this application.

[0076] Based on the above embodiments, other embodiments can be obtained, which will be described below.

[0077] Figure 5 This is a cross-sectional view of the lens assembly 21, variable aperture assembly 27, first housing 22, and circuit board module 25, etc., in another embodiment. (Combined with...) Figure 3 and Figure 5 As shown, Figure 5 The illustrated embodiments and Figure 3 The difference in the illustrated embodiment is that the end of the conductive line 26 facing away from the first housing 22 is fixed to the side of the circuit board 251 facing the first housing 22. This fixing method can shorten the length of the conductive line 26, reduce the influence of resistance on signal transmission, and also avoid bending of the conductive line 26, thereby enhancing the stability of the connection.

[0078] Figure 6 This is a cross-sectional structural schematic diagram of the lens assembly 21, variable aperture assembly 27, first housing 22, and external power supply 29, etc., in another embodiment. (Combined with...) Figure 3 and Figure 6 As shown, Figure 6 The illustrated embodiments and Figure 3The difference in the illustrated embodiment is that the drive component 271 can be connected to an external power supply 29 instead of the circuit board 251, receiving power and signals from the external power supply 29 to control the drive component 271 to drive the aperture body 272 to switch the aperture size. Connecting the variable aperture component 27 to the external power supply 29 avoids electromagnetic interference from devices such as the image sensor 252 on the circuit board 251 to the variable aperture component 27, and reduces the wiring complexity inside the vehicle camera module 20, making the structure of the vehicle camera module 20 more compact.
