Along with the development of automobile intellectualization, the application of the vehicle-mounted camera is more and more popular. A common way to mount a vehicle-mounted camera to a vehicle is to: the pitching angle of the camera relative to the mounting bracket is adjusted according to the vehicle type of the vehicle-mounted camera, then the camera is fixed on the mounting bracket, then 3M glue is coated on one surface of the mounting bracket, and the surface is bonded on the inner side of the windshield of the vehicle, so that the vehicle-mounted camera is mounted. Therefore, the mounted vehicle-mounted camera is positioned on the inner side of the windshield and below the windshield. Due to the alternating change of the temperature inside the vehicle, when condensed water appears on the inner side of the windshield, the condensed water may permeate into the vehicle-mounted camera. The condensed water contacts with devices such as a circuit board, a lens module and a chip in the vehicle-mounted camera, and the circuit board, the lens module and the chip are short-circuited or corroded and damaged.

In order to solve the above technical problem, please refer to fig. 1 to 4, the utility model provides a vehicle-mounted camera device, this vehicle-mounted camera device can prevent that the inboard comdenstion water of windshield from permeating in the vehicle-mounted camera device.

Referring to fig. 1 to 3, the present invention provides a vehicle-mounted camera device, which comprises a top shell 10 and a bottom shell 20, wherein the top shell 10 is spliced with the bottom shell 20 to form a cavity, and the edge of the bottom shell 20 is adapted to the top shell 10. The vehicle-mounted camera device further comprises a lens module 30, wherein the lens module 30 is mounted on one of the top shell 10 and the bottom shell 20, and a part of the lens module 30 is positioned in the cavity.

For convenience of description, the structure and principle of the vehicle-mounted camera device will be described in detail by taking the lens module 30 mounted on the top case 10 as an example, and the description of the case where the lens module 30 is mounted on the bottom case 20 will not be repeated. And is defined as follows: in a state where the in-vehicle imaging device is mounted inside the windshield, the upper end of the water guide portion 11 is an upper water guide end 111, and the lower end of the water guide portion 11 is a lower water guide end 112, as shown in fig. 1 and 2.

It will be appreciated that the onboard camera is mounted inside the windscreen, below which it is located, and the top shell 10 is located above the bottom shell 20. When the condensed water formed on the windshield flows to the vehicle-mounted image pickup device, it flows to the top case 10 first.
