[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] This utility model embodiment provides a vehicle-mounted camera module 100, such as Figures 1 to 5 As shown, the vehicle-mounted camera module 100 includes a housing 1, an optical transceiver module 2, an optical-electric composite cable 3, and a camera module 4. The housing 1 has a through-hole 1213 at one end, which communicates with the interior of the housing 1. The optical transceiver module 2 includes a first circuit board 21 and an optical transceiver assembly 22. The first circuit board 21 is located inside the housing 1 and includes a base plate 211 and at least one side plate 212. The base plate 211 and the side plate 212 are set at an angle and define an assembly space 214 with the housing 1. The optical transceiver assembly 22 is located on the base plate 211 and is housed in the assembly space 214. The optoelectronic composite cable 3 contains a cable 311 and an optical fiber 312. One end of the optoelectronic composite cable 3 extends through the through-hole 1213 into the assembly space 214 so that the cable 311 is connected to the first circuit board 21 and the optical fiber 312 is connected to the optical transceiver assembly 22. The other end of the optoelectronic composite cable 3 is provided with an optoelectronic composite connector 313. The camera module 4 is located at the end of the housing 1 away from the through-hole 1213 and is connected to the base plate 211.

[0019] Specifically, the first circuit board 21 includes a base plate 211 and at least one side plate 212, and the base plate 211 and the side plate 212 are arranged at an angle inside the housing 1, so that the base plate 211 and the side plate 212 can define an assembly space 214 with the housing 1, thereby enabling the first circuit board 21 to form a three-dimensional assembly and ensuring that the base plate 211 and the side plate 212 can make full use of the space inside the housing 1. Furthermore, the optical transceiver assembly 22 is mounted on the base plate 211 and housed within the assembly space 214, and one end of the optoelectronic composite cable 3 can extend through the opening 1213 of the housing 1 into the assembly space 214, so that the cable 311 in the optoelectronic composite cable 3 can be connected to the first circuit board 21 within the assembly space 214, and the optical fiber 312 in the optoelectronic composite cable 3 can be connected to the optical transceiver assembly 22 within the assembly space 214. Through this layout, the connection, fixation, and housing between the optical transceiver assembly 22, the cable 311, the optical fiber 312, and the first circuit board 21 can be realized in the assembly space 214, thereby achieving a compact layout inside the vehicle camera module 100, effectively reducing the volume of the vehicle camera module 100, and meeting the requirements of modern vehicles for miniaturization and lightweighting of the vehicle camera module 100.

[0020] Furthermore, the cable 311 of the optoelectronic composite cable 3, which passes through the assembly space 214, is connected to the first circuit board 21, and the optical fiber 312 is connected to the optical transceiver assembly 22. The other end of the optoelectronic composite cable 3 is equipped with an optoelectronic composite connector 313. Thus, the optoelectronic composite cable 3 can be conveniently connected to the vehicle's central control system via the optoelectronic composite connector 313. The optical fiber 312 within the optoelectronic composite cable 3 is primarily used for high-speed data transmission. Utilizing the characteristics of optical signals, it enables high-capacity, high-speed data communication, meeting the high-speed data transmission requirements of modern automobiles, such as autonomous driving assistance systems and high-definition video transmission. The cable 311 within the optoelectronic composite cable 3 undertakes power transmission and some low-speed signal transmission, providing necessary power support for the vehicle camera module 100. Furthermore, forming the optoelectronic composite cable 3 with the optical fiber 312 and cable 311 helps to improve the lightweighting and integration of the wiring harness between the vehicle camera module 100 and the vehicle's central control system.

[0021] The camera module 4 is located at the end of the housing 1 away from the opening 1213 and is connected to the base plate 211. This allows the camera module 4 to connect with the optical transceiver module 2. Firstly, the camera module 4 can transmit the acquired vehicle perimeter image information to the optical transceiver assembly 22 on the base plate 211, and then transmit it to the vehicle's central control system via the optical transceiver assembly 22 and optical fiber 312. This enables the central control system to quickly acquire the vehicle perimeter image information and perform lane recognition and reversing guidance, among other driver assistance functions. Secondly, the cable 311 provides power to the camera module 4 through the first circuit board 21, ensuring its operation.

[0022] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 2 to 3 As shown, the first circuit board 21 also includes at least one flexible board 213, which is disposed between the base plate 211 and the side plate 212 and is electrically connected to the base plate 211 and the side plate 212 respectively.

[0023] Specifically, the flexible board 213 is disposed between the base plate 211 and the side plate 212, and is electrically connected to both the base plate 211 and the side plate 212. Thus, on the one hand, the flexible board 213 enables an integrated arrangement of the base plate 211 and the side plate 212 while ensuring electrical connection between them. Compared to a separate arrangement of the base plate 211 and the side plate 212, this avoids the cumbersome assembly requiring manual wiring between them, and prevents the wiring from becoming cluttered within the assembly space 214. On the other hand, the flexible board 213, while connecting the base plate 211 and the side plate 212, can be bent so that the base plate 211 and the side plate 212 can be angled and positioned inside the housing 1.

[0024] More specifically, such as Figures 2 to 3 As shown, the first circuit board 21 includes a base plate 211, two side plates 212, and two flexible circuit boards 213. The base plate 211 and the side plates 212 are electrically connected through a flexible circuit board 213. The base plate 211 is parallel to the end wall of the housing 1. The two side plates 212 are located between the base plate 211 and the through-hole 1213, and are parallel to one side wall of the housing 1, respectively. Thus, the base plate 211 and the side plates 212 can be arranged at a 90° angle inside the housing 1, making full use of the three-dimensional space inside the housing 1. In addition, while the optical transceiver assembly 22 is disposed on the base plate 211, one of the two side plates 212 can be equipped with a larger MAC chip, while the other side plate 212 can integrate other smaller components, thereby optimizing the layout of components on the first circuit board 21 and making the overall layout of the first circuit board 21 more compact.

[0025] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 5 As shown, the housing 1 includes a first half-shell 11 and a second half-shell 12. The first half-shell 11 and the second half-shell 12 are respectively provided with a first mounting groove 111 and a second mounting groove 121. The through-hole 1213 is provided at the bottom of the second mounting groove 121. The first mounting groove 111 and the second mounting groove 121 communicate to form a receiving cavity 13. The camera module 4 and the optical transceiver module 2 are housed in the receiving cavity 13.

[0026] Specifically, the housing 1 includes a first half-shell 11 and a second half-shell 12. The first half-shell 11 and the second half-shell 12 are respectively provided with a first mounting groove 111 and a second mounting groove 121. The first mounting groove 111 and the second mounting groove 121 communicate to form a receiving cavity 13, thereby providing installation space for the camera module 4 and the optical transceiver module 2. Specifically, the camera module 4 and the optical transceiver module 2 can be positioned and installed into the first mounting groove 111 and the second mounting groove 121 respectively, and then the first half-shell 11 and the second half-shell 12 can be assembled to form a modular assembly. This ensures that the camera module 4 and the optical transceiver module 2 can be accurately and conveniently installed, improving assembly quality and efficiency.

[0027] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 4 As shown, mounting posts 1211 protrude from the adjacent junctions of two adjacent sidewalls of the second mounting groove 121. Side plate 212 is sandwiched between two adjacent mounting posts 1211 along the sidewall of the second mounting groove 121, and bottom plate 211 is fixed to mounting posts 1211.

[0028] Specifically, mounting posts 1211 are provided at the junction of two adjacent side walls of the second mounting groove 121. The mounting posts 1211 can provide positioning and installation for the side plate 212 and the bottom plate 211, so that the side plate 212 can be sandwiched between two adjacent mounting posts 1211 along the side wall of the second mounting groove 121, and the bottom plate 211 can be fixed to the mounting posts 1211, ensuring the stability of the installation of the side plate 212 and the bottom plate 211 inside the housing 1 and reducing the risk of loosening due to vibration or impact.

[0029] More specifically, such as Figures 4 to 5 As shown, the top of the mounting post 1211 is close to the opening of the second mounting groove 121, and a mounting position is formed near the opening of the second mounting groove 121. This allows the base plate 211 to be accommodated in the mounting position when it is fixed to the top of the mounting post 1211, so that the base plate 211 can be flush with the opening of the second mounting groove 121. Furthermore, the bottom end of the mounting post 1211 extends to the bottom of the second mounting groove 121, allowing the side plate 212 to be sandwiched between two adjacent mounting posts 1211 along the side wall of the second mounting groove 121 and abut against the bottom of the second mounting groove 121. This ensures that the base plate 211 and the side plate 212 can be tightly installed within the second mounting groove 121, fully utilizing the space of the second mounting groove 121 and reducing the volume of the second housing 1.

[0030] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 4 As shown, the side wall of the mounting column 1211 is provided with a fixing groove 1211a, and the two sides of the side plate 212 are accommodated in the fixing groove 1211a.

[0031] Specifically, the side wall of the mounting post 1211 is provided with a fixing groove 1211a. The fixing groove 1211a can provide a precise fixing position for the side plate 212, so that both sides of the side plate 212 can be accommodated in the fixing groove 1211a for limiting and fixing during installation. It is worth mentioning that, in order to ensure the stability of the side plate 212 installation, the side plate 212 can be bonded to the side wall of the second mounting groove 121 and the fixing groove 1211a with adhesive.

[0032] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 5 As shown, the vehicle camera module 100 also includes a fixing component 5, which includes a first fixing tube 51 and a second fixing tube 52. The first fixing tube 51 is sleeved on the optoelectronic composite cable 3. The first fixing tube 51 includes a protruding edge 511 and a connecting part 512. The protruding edge 511 is limited to the bottom of the second mounting groove 121. The connecting part 512 is exposed outside the second half shell 12. The second fixing tube 52 is sleeved outside the connecting part 512 and fixed to the outer wall of the second half shell 12.

[0033] Specifically, the first fixing tube 51 is sleeved on the optoelectronic composite cable 3, and the protruding edge 511 of the first fixing tube 51 is limited to the bottom of the second mounting groove 121. Thus, the portion of the optoelectronic composite cable 3 inside the housing 1 can be fixed by the limiting cooperation between the protruding edge 511 and the bottom of the groove. Furthermore, the connecting part 512 of the first fixing tube 51 is exposed outside the second half-shell 12, and the second fixing tube 52 is sleeved outside the connecting part 512 and fixed to the outer wall of the second half-shell 12. Thus, the portion of the optoelectronic composite cable 3 outside the housing 1 can be fixed to the outer wall of the second half-shell 12 by the cooperation of the connecting part 512 of the first fixing tube 51 and the second fixing tube 52, thereby ensuring a stable connection between the optoelectronic composite cable 3 and the housing 1 and preventing the optoelectronic composite cable 3 from detaching from the housing 1.

[0034] More specifically, such as Figures 2 to 4 As shown, the first fixing tube 51 is glued to the optoelectronic composite cable 3, thereby achieving a stable connection between the first fixing tube 51 and the optoelectronic composite cable 3. The outer wall of the connecting portion 512 of the first fixing tube 51 is provided with a connecting thread 5121, and the inner wall of the second fixing tube 52 is provided with a threaded groove. The second fixing tube 52 is fitted onto the connecting portion 512 through the connecting thread 5121 and the threaded groove, thereby achieving a stable connection between the first fixing tube 51 and the second fixing tube 52. Furthermore, the outer wall of the second fixing tube 52 is also provided with a tightening part, which can cooperate with a wrench so that the wrench can act on the second fixing tube 52, causing the second fixing tube 52 to tighten onto the first fixing tube 51, thus abutting against the outer wall of the second half-shell 12.

[0035] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 2 to 4As shown, the peripheral wall of the protruding edge 511 is provided with a positioning block 5111, and the bottom of the second mounting groove 121 is provided with a limiting groove 1212 that communicates with the through opening 1213. The protruding edge 511 passes through the through opening 1213 and is limited to the bottom of the second mounting groove 121, so that the positioning block 5111 is limited to the limiting groove 1212.

[0036] By implementing this embodiment, while the protruding edge 511 passes through the opening 1213 and is limited to the bottom of the second mounting groove 121, the positioning block 5111 on the peripheral wall of the protruding edge 511 can be limited to the limiting groove 1212, thereby restricting the rotation of the optoelectronic composite cable 3 within the opening 1213, avoiding the risk of the optical fiber 312 and cable 311 of the optoelectronic composite cable 3 becoming tangled or broken due to rotation, improving the service life and reliability of the optoelectronic composite cable 3, preventing the optical fiber 312 from being broken between the optical transceiver component 22 and the cable 311 from being broken between the first circuit board 21, and ensuring the normal operation of the vehicle camera module 100.

[0037] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 3 As shown, the second fixing tube 52 is fixed to the outer wall of the second half shell 12 at one end, and a first sealing groove 521 is provided in the first sealing groove 521. A first sealing element is provided in the first sealing groove 521, and a sealing sleeve is provided on the other end of the second fixing tube 52. Specifically, the end of the second fixing tube 52 that is fixed to the outer wall of the second half-shell 12 is provided with a first sealing groove 521, and a first sealing element is provided in the first sealing groove 521. The first sealing element can ensure the sealing between the second fixing tube 52 and the second half-shell 12. Furthermore, a sealing sleeve is provided over the other end of the second fixing tube 52, which can ensure the sealing of the other end of the second fixing tube 52. The first sealing element and the sealing sleeve form a double seal, preventing external dust, moisture, and other impurities from entering the housing 1, effectively improving the waterproof and dustproof capabilities of the entire vehicle camera module 100, and achieving IP6 dustproof and waterproof level for the first sealing element of the tightening part 7.

[0038] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 5 As shown, a second sealing groove 122 is provided at one end of the first half-shell 11 away from the bottom of the first mounting groove 111 and at one end of the second half-shell 12 away from the bottom of the second mounting groove 121, and a second sealing element is provided in the second sealing groove 122.

[0039] Specifically, a second sealing groove 122 is provided at one end of the first half-shell 11 away from the bottom of the first mounting groove 111 and at one end of the second half-shell 12 away from the bottom of the second mounting groove 121. A second sealing element is provided in the second sealing groove 122. The second sealing element can form a seal between the first half-shell 11 and the second half-shell 12, effectively preventing external dust and moisture and other impurities from entering the interior of the housing 1 from between the first half-shell 11 and the second half-shell 12, and effectively improving the waterproof and dustproof capabilities of the entire vehicle camera module 100.

[0040] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the camera module 4 is arranged opposite to the base plate 211. The side of the camera module 4 facing the base plate 211 is provided with a first connector 411, and the side of the base plate 211 facing the camera module 4 is provided with a second connector 2111. The first connector 411 and the second connector 2111 are connected.

[0041] Specifically, the camera module 4 has a first connector 411 on the side facing the base plate 211, and the base plate 211 has a second connector 2111 on the side facing the camera module 4. The first connector 411 and the second connector 2111 are connected to achieve an electrical connection between the camera module 4 and the base plate 211. During assembly, simply aligning the first connector 411 and the second connector 2111 is sufficient to connect the camera module 4 and the base plate 211, reducing assembly steps and improving assembly efficiency. Furthermore, since the first connector 411 and the second connector 2111 are miniaturized and integrated, compared to soldering or hard-wired connections, they require less space, resulting in a more compact layout between the camera module 4 and the base plate 211, effectively saving space inside the housing 1.
