[0024] Figure 1 It is a schematic diagram of the three-dimensional structure of the vehicle-mounted camera device provided in an embodiment of the present disclosure.

[0025] The embodiment of the present disclosure provides a vehicle-mounted camera device 1 , which includes a camera module 10 , a camera module carrier 20 , a first printed circuit board assembly 30 and a housing 40 .

[0026] Figure 4 Schematic diagram of the structure of the camera module provided by the embodiment of the present disclosure. Figure 4 As shown, the camera module 10 includes a lens 11, a lens bracket 13 and a second printed circuit board assembly 12. The lens 11 is mounted on the second printed circuit board assembly 12 via the lens bracket 13. The lens bracket is formed with a clamping portion 131 for clamping by a clamping claw. In this embodiment, the clamping portion 131 is formed on two opposite sides of the lens bracket 12. The clamping portion 131 can withstand a large pressure, so it can be clamped by the clamping claw to adjust the angle of the camera module 10.

[0027] like Figure 1 , 5 As shown, the camera module carrier 20 has a first opening 21 for accommodating the camera module 10. The camera module 10 is installed in the first opening 21. The first opening 21 includes a first opening 211 for the camera module 10 to enter and a second opening 212 for the lens to be exposed, so that the camera module 10 can be accommodated in the camera module carrier 20, and can collect ambient light and generate an image based on the collected ambient light.

[0028] A glue groove is formed above the first opening 21 for injecting glue to bond the camera module 10 and the camera module carrier 20 after the camera module 10 is installed in the camera module carrier 20 , thereby fixing the camera module 10 .

[0029] The camera module 10 is electrically connected to the first PCB assembly 30. Specifically, the second PCB assembly 12 of the camera module 10 is electrically connected to the first PCB assembly 30. The housing 30 is coupled to the camera module carrier 20 to enclose the camera module 10 and the first PCB assembly 30.

[0030] Figure 2 4 is a flow chart of a method for manufacturing a vehicle-mounted camera device provided in an embodiment of the present disclosure.

[0031] The vehicle-mounted camera device 1 may be an advanced driver assistance system (ADAS) camera. The vehicle-mounted camera device 1 includes a camera module 10, a camera module carrier 20, a first printed circuit board assembly 30, and a housing 40. The camera module carrier 20 has a first opening 21 for accommodating the camera module 10. The camera module 10 is installed in the first opening 21. The first opening 21 includes a first opening 211 for the camera module 10 to enter and a second opening 212 for the lens to be exposed, so that the camera module 10 can be accommodated in the camera module carrier 20, and can collect ambient light, and generate an image based on the collected ambient light.

[0032] S101: Fix the camera module carrier 20 so that the hole axis of the first opening 21 is in a horizontal state.

[0033] Here, the camera module carrier 20 can be fixed by a carrier (such as a fixture), and the hole axis F of the first opening 21 is as follows: Figure 3 As shown in the figure, it is in a horizontal state to facilitate the installation of the camera module 10. When the camera module 10 is installed in the first opening 21, the optical axis of the camera module 10 should coincide with the hole axis F of the first opening 21.

[0034] S102 : Using a clamping jaw, the camera module 10 is installed in the first opening 21 of the camera module carrier 20 in such a way that the optical axis F1 of the camera module 10 coincides with the hole axis F of the first opening 21 .

[0035] like Figure 3 As shown, first, the camera module 10 is clamped by the clamping claws so that its optical axis F1 is also in a horizontal state. Then, the camera module 10 is installed in the first opening 21 of the camera module carrier 20 in a manner that the optical axis F1 of the camera module 10 is aligned with the hole axis F of the first opening 21, so that the optical axis F1 of the camera module 10 coincides with the hole axis F of the first opening 21.

[0036] like Figure 4 As shown, the camera module 10 includes a lens 11, a lens bracket 13 and a second printed circuit board assembly 12. The lens 11 is mounted on the second printed circuit board assembly 12 via the lens bracket 13. The lens bracket is formed with a clamping portion 131 for clamping by a clamping claw. The clamping portion 131 can withstand a large pressure. When the camera module 10 is installed, the clamping claw is clamped on the clamping portion 131.

[0037] In addition, if Figure 1 and Figure 5As shown, the first opening 21 includes a first opening 211 for the camera module to enter and a second opening 212 for the lens to be exposed. The first opening 211 is wider than the second printed circuit board assembly 12 in the transverse direction, so that two opposing gaps L1 and L2 are formed between the first opening 211 and the second printed circuit board assembly 13. The gaps L1 and L2 are for the clamping claws to extend into when installing and calibrating the camera module.

[0038] S103: Calibrate the camera module 10 using the clamping claws.

[0039] After the clamping jaws install the camera module 10 on the camera module carrier 20, the clamping jaws are still required to calibrate the camera module 10. Specifically, the clamping jaws are used to rotate the camera module 10 until the lens 11 reaches a preset effect. The rotation angle range here is a relatively small angle. For example, the preset effect can be confirmed by a camera placed in front of the camera module 10 to confirm whether the pixels of the photosensitive chip of the camera module 10 are horizontally arranged.

[0040] S104 : injecting glue into the glue groove 22 and solidifying the glue to bond the camera module 10 and the camera module carrier 20 .

[0041] After calibrating the camera module 10, a colloid is injected into the glue groove 22, and the colloid is cured to bond the camera module 10 and the camera module carrier 20. The colloid may be a colloid sensitive to ultraviolet (UV) light, and the colloid is cured by UV light after the colloid is injected.

[0042] S105: Install the first printed circuit board assembly 30, and electrically connect the camera module 10 to the first printed circuit board assembly 30. For example, the electrical connection may be through an interface.

[0043] S106 : Joining the housing 40 and the camera module carrier 20 to seal the camera module 10 and the first printed circuit board assembly 30 .

[0044] like Figure 6 As shown, after the first printed circuit board assembly 30 is installed and the camera module 10 is electrically connected to the first printed circuit board assembly 30, the shell 40 can be joined to the camera module carrier 20, and the shell 40 and the camera module carrier 20 can be fixed by fasteners (such as screws, etc.), thereby enclosing the camera module 10 and the first printed circuit board assembly 30, with only the interface exposed.

[0045] Through the above steps, a vehicle-mounted camera device with better performance can be manufactured with higher production efficiency.
