Definitions
- the invention relates to a camera module, which can be used in particular in a vehicle for surround view, rear view or exterior mirror replacement driver assistance solutions.
- the invention has for its object to provide a camera module with optimized concept for heat dissipation.
- the starting point of the invention are the following considerations:
- Camera housing is in particular in a direct thermal connection of the heat sources to the lateral camera outer surfaces, whereby the heat derived directly from the housing.
- the circuit boards (1 a, 1 b, 1 c) arranged in U-shape or in H-shape (1) and mounted on a metallic support (5).
- the carrier (5) serves for heat distribution in the interior of the camera module and also for dissipating the heat in the camera module along the metallic carrier (5) to the outer surfaces.
- the direct connection of the main heat sources eg processor ICs
- the inner metallic support (5) allows easy mounting of the circuit boards (1 a, 1 b, 1 c) around the support
- the inner metallic carrier (5) serves for the additional heat distribution and heat dissipation from the interior of the camera module to the
- the metallic support (5) serves as a receptacle for the
- the carrier can serve in the inner part as a receptacle for a connector solution (6) for connecting a data transmission cable (7)
- FIG. 1 a shows a first printed circuit board (1 b) which is connected via a flex connector (1 d) to a second printed circuit board (1 a) and via a further flexible connector (1 e) to a third printed circuit board (1 c).
- FIG. 1 b shows a perspective view of a printed circuit board arrangement (1) of the printed circuit boards shown in FIG. 1 a.
- the first (1 b) and third (1 c) circuit board are arranged parallel to each other and spaced by the arranged perpendicular to both second circuit board (1 a).
- This printed circuit board assembly (1) can be referred to as U- or H-shaped.
- FIG. 2 the circuit board assembly (1) of FIG. 1 b is shown rotated, wherein on the underside of the second circuit board (1 a) an image sensor (3), for example, a CMOS or CCD sensor with a downwardly active image-receiving surface for the spatially resolved detection of incoming electromagnetic radiation in the
- first printed circuit board (1b) On the outside of the first printed circuit board (1b) is a first electronic component (2a), e.g. a processor and on the outside of the third printed circuit board (1 c) is a second electronic component (2b), e.g. a memory element arranged.
- a flex connector (1 d) extends over the inside of the first circuit board (1 b) to the second circuit board.
- Another flex connector (1 e) runs freely between the first and third circuit board (1 b and 1 c).
- Fig. 3 shows an exploded view of a camera module with a connected via a connector end of a data transmission cable (7), which may be in particular a LVDS cable (Low Voltage Differential Signaling cable).
- the middle elements are those shown in FIG.
- two thermally conductive elements (4a and 4b) e.g. two thermally conductive pads, a metallic carrier (5) with connected thereto
- Fig. 4 shows the structure of the camera module within the housing (8), which results by assembling the corresponding components shown in Fig. 3.
- the first and third circuit boards (1 b and 1 c) are mounted on the metallic support (5), so that the metallic support heat from these circuit boards and take to its top or outside (there is also the
- Data transmission cable (7) connected can derive.
- heat-producing electronic components (2a, 2b) are thermally directly to the housing (8) and thus to the side via two thermally conductive elements (4a, 4b), such as thermal paste or thermally conductive pads
- FIG. 5 essentially shows a rotated representation of the components shown in FIG. 4, the inner components (1-5) of the camera module being inserted further into the housing (8) and additionally the lens holder (10) having a seal (9). is shown.
- the lens holder is used during assembly of the
- the camera module through an opening in the housing (8) in a receiving area of the metallic carrier (5) in front of the image sensor (3) pushed and fixed.
- the camera module is extremely compact, which among other things by the PCB assembly (1), the Sterckverbinderaims on the opposite side of the lens
- the heat dissipation concept is not overly strong.
- the extension of the camera module transversely to the optical axis is very small, so it can be achieved that the lens occupies at least 20% of the camera module dimension transverse to the optical axis.
- the camera module is sealed by the housing (8), the seal (9) and the lens holder (10) with lens well against environmental influences and can thus be used as a vehicle exterior camera as part of a surround view, rear view or mirror replacement driver assistance system.
