The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

referring to fig. 1, the present invention discloses a vehicle-mounted camera 1, which includes a housing body 2, a housing front cover 3, a housing rear cover 4, a first substrate unit 5, a second substrate unit 6, a spacer 7, a third substrate unit 8 and a lens module 9.

In this embodiment, the housing body 2 has a receiving space, a first substrate unit 5 having an image signal processing unit (not shown) is disposed in the receiving space, and a second substrate unit 6 is disposed in the receiving space, wherein the first substrate unit 5 has a first connector 51, and the second substrate unit 6 has a second connector 61 and is electrically connected to the first connector 51 of the first substrate unit 5.

Wherein the casing body 2 is respectively fixedly connected with the casing front cover 3 and the casing rear cover 4 by screws, but not limited thereto, the casing body 2 can be integrally formed or formed by combining more parts, or the casing body 2 is respectively integrally formed with the casing front cover 3 and the casing rear cover 4, etc., or each part is fixed by gluing or buckling. The casing body 2, the casing front cover 3 and the casing rear cover 4 are made of metal materials with good rigidity and thermal conductivity, such as copper, aluminum, iron or alloys thereof.

The front cover 3 has a mounting hole, and a lens module 9 is disposed in the mounting hole. Wherein, the lens module 9 and the mounting hole can be filled with a sealing glue, such as a UV curing glue, so as to achieve the fixing, waterproof and dustproof functions. Or, the lens module 9 and the mounting hole have corresponding threads respectively, and are fixed by screw-locking and then reinforced by waterproof glue.

The first substrate unit 5 generally has an Image Signal Processor (ISP) for performing Image Signal processing, and converts the Signal output from the Image sensor into standard full color (e.g., sRGB or similar color representation, or further compressed into a suitable format). The main process comprises complex modules of demosaicing, noise reduction, white balance, exposure correction, sharpening, color conversion, color correction, gamma correction, color space conversion, edge enhancement processing, coding and the like, or further comprises the work of data compression, rear-end interface control, data transmission, control and the like, and also comprises the work of LCD image preview, lens focusing control, interface use and the like.

The second substrate unit 6 mainly provides a power supply and signal transmission for the related circuits of the vehicle-mounted camera 1, but not limited thereto, and the second substrate unit 6 may also include an image processing function and has a data format conversion or related artificial intelligence module, such as an object identification or an object distance detection function.

Referring to fig. 2 and fig. 3, the spacer 7 is located between the first substrate unit 5 and the second substrate unit 6, and fixed to the housing body 2 together with the first substrate unit 5 and the second substrate unit 6, which is usually fixed by screw locking. Because the spacer 7 is disposed between the first substrate unit 5 and the second substrate unit 6, high temperature generated by the first substrate unit 5 and the second substrate unit 6 when the vehicle-mounted camera 1 operates can be conducted to the housing body, and a good heat dissipation effect is achieved.

Referring to fig. 4, in order to achieve better heat dissipation effect, a connection bump 21 is provided between the spacer 7 and the housing body 2. In the present embodiment, the connecting projection 21 is integrally formed with the housing body 2, but the connecting projection 21 may be integrally formed with the spacer 7 (not shown). By the arrangement of the connecting bump 21, the contact area between the spacer 7 and the housing body 2 and the contact stress when the spacer and the housing body are fixed are increased, so that the heat conduction efficiency is increased, a good heat dissipation effect is achieved, and the heat conduction efficiency is increased. Meanwhile, in the present embodiment, the first heat conduction layer 100 may be added to the surface of the connection between the connection bump 21 and the spacer 7. If the connection protrusions 21 are integrally formed with the spacer 7, the first heat conduction layer 100 may be disposed between the connection protrusions 21 and the surface of the housing body 2. The first heat conduction layer may be made of a metal material with better heat conductivity, such as silver, copper, aluminum or an alloy thereof, or may be made of a non-metal material with higher heat conductivity, such as graphite and Graphene (Graphene), or may be made of organic silicon gel as a main body, and polymer materials, such as fillers and heat conduction materials, are added and mixed, or may be made of heat conduction silicon gel, heat conduction silicon rubber, epoxy resin AB glue, polyurethane heat conduction glue, and the like. Similarly, a second heat conduction layer 200 can be disposed on the thermally-highly-thermally-generated areas of the first substrate unit 5 and the second substrate unit 6, and due to the disposition of the spacers 7, the disposition of the second heat conduction layer 200 on the first substrate unit 5 and the second substrate unit 6 is not limited as long as the spacers 7 can cover the second heat conduction layer 200. Due to the arrangement of the spacer 7, the heat generated by the first substrate unit 5 and the second substrate unit 6 is more easily dissipated from the housing body 2 when the vehicle-mounted camera 1 is in operation, and in addition, because the first substrate unit 5 and the third substrate unit 8 are mainly sources of high heat, and the two substrate units are very close to each other, the heat generated by the first substrate unit 5 can be conducted to the housing body 2 through the spacer 7 by the arrangement of the spacer 7, so that the heat conduction path is increased, and the damage influence caused by the heat to the interior of the vehicle-mounted camera is reduced.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
