Abstract
Description
Technical Field
[0001] The utility model discloses a low-cost heat dissipation vehicle-mounted camera, belonging to the field of vehicle-mounted cameras. Background Art
[0002] With the development of the times, the functional requirements for vehicle-mounted cameras have also changed. In order to achieve functions such as obstacle distance detection, sign line recognition, local magnification, dynamic and static auxiliary lines, some models have higher and higher requirements for camera image sensor resolution and image processing, and the power consumption of the camera is also getting higher and higher.
[0003] The shell of existing vehicle-mounted camera components is generally a plastic shell or a metal shell. Traditional plastics are generally only used in cameras with fewer functions and low power consumption due to their poor heat dissipation capabilities. Traditional metal shells are often used in cameras with high pixels, multiple functions, and high power consumption.
[0004] Due to the structural limitations of the existing vehicle body, the existing incoming line connector is embedded in the rear cover. If the rear cover (including the incoming line connector) is made of metal material, firstly, the cost will increase due to the metal material, and secondly, after the metal rear cover is manufactured, it needs milling, vibration grinding, oxidation treatment and other processes before it can be assembled with the incoming line connector. The production requirements of the corresponding workshop are also higher and the process is complicated. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model aims to provide a low-cost heat dissipation vehicle-mounted camera to solve the problem.
[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a low-cost heat dissipation vehicle-mounted camera, including a metal front shell, a plastic back cover, a circuit board, a lens, and a heat-conducting component; the plastic back cover is installed on the metal front shell, so that the interior of the metal front shell forms an installation cavity, and the installation cavity is used for installing the heat-conducting component and the circuit board; the plastic back cover is provided with an inclined incoming line connector, and the incoming line connector is connected to the circuit board in the installation cavity; the lens corresponds to the circuit board; and the heat-conducting component acts on the circuit board.
[0007] Preferably, the metal front shell is used to mount a lens.
[0008] Preferably, the heat-conducting assembly comprises a metal rear cover plate and a thermal pad; the metal rear cover plate constitutes the bottom of the mounting cavity, and the circuit board placed in the mounting cavity contacts the metal rear cover plate through the thermal pad.
[0009] Preferably, the metal front shell and the plastic rear cover are fixedly connected by bolts; and the metal front shell and the plastic rear cover clamp the metal rear cover plate, so that the metal rear cover plate is fixed on the plastic rear cover.
[0010] Preferably, a sealing ring is provided at the bottom of the metal front shell to ensure that the metal front shell fits tightly with the metal rear cover plate.
[0011] Preferably, the metal rear cover has a protrusion, and the thermal pad is placed between the circuit board and the protrusion, so that the heat generated by the circuit board is transferred to the metal rear cover by the thermal pad.
[0012] Preferably, the incoming line connector is embedded in the plastic back cover.
[0013] Preferably, the circuit board is bonded in the mounting cavity.
[0014] Beneficial Effects
[0015] The utility model reduces manufacturing costs by using a plastic back cover made of plastic that is easier to produce, and can produce the required back cover more simply based on the excellent plasticity of plastic, thereby reducing manufacturing requirements. The heat dissipation efficiency is ensured by the heat conduction component, so that the camera is still suitable for cameras with high pixels, multiple functions, and high power consumption.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] See also Figure 1-Figure 4 The utility model provides a low-cost heat dissipation vehicle camera technical solution: used for heat dissipation of a circuit board 5 corresponding to an existing lens 1. The structure includes a metal front shell 2, a plastic back cover 3, and a heat conduction component 4.
[0023] The metal front shell 2 is a thin shell, and after being assembled with the plastic back cover 3, a mounting cavity A is formed inside the metal front shell 2. The metal front shell 2 has a port 21 for mounting the lens 1, so that the lens 1 corresponds to the circuit board 5 in the mounting cavity A after being mounted.
[0024] The circuit board 5 is connected with a conductive wire (not shown in the figure); the circuit board 5 has a heat dissipation window 51; the circuit board 5 and the circuit elements and conductive wires installed thereon are all circuit components used by existing conventional vehicle-mounted cameras, and the components can be directly purchased on the market according to demand, so this specification does not elaborate on the circuit structure and circuit principle of the circuit component. Preferably, the circuit board 5 is installed in the installation cavity A; the conductive wire is connected to the circuit board 5 from the incoming line connector 31.
[0025] The installation cavity A is used for installing the heat-conducting component 4 and the circuit board 5 .
[0026] The heat-conducting component 4 includes a metal back cover 41 and a heat-conducting pad 42; the metal back cover 41 constitutes the bottom of the installation cavity A, and the circuit board 5 placed in the installation cavity A contacts the metal back cover 41 through the heat-conducting pad 42. In this way, the heat generated by the circuit board 5 is transferred to the metal back cover 41 for heat dissipation. Further, there is a protrusion 410 on the metal back cover 41, and the heat-conducting pad 42 is placed between the circuit board 5 and the protrusion 410, which plays a role in facilitating positioning and installation, so that the heat dissipation window 51 on the circuit board 5 can be directly connected to the heat-conducting pad 42 to the metal back cover 41 (protrusion 410). In one embodiment, in order to prevent the circuit board 5 from falling off from the installation cavity A, one is to support the circuit board 5 by the above-mentioned protrusion 410, and the other is to reserve a certain gap between the circuit board 5 and the installation cavity A, and fill the gap with UV glue to make the circuit board 5 adhere to the installation cavity A.
[0027] The metal rear cover plate 41 can be made of copper, for example, which has good thermal conductivity.
[0028] The metal front shell 2 and the plastic rear cover 3 are fixedly connected by bolts; and the metal front shell 2 and the plastic rear cover 3 clamp the metal rear cover plate 41 so that the metal rear cover plate 41 is fixed on the plastic rear cover 3 .
[0029] The incoming line connector 31 is embedded in the plastic rear cover 3; wherein the incoming line connector 31 can be tilted to be adjusted and installed according to the vehicle model, so as to facilitate the installation of the entire device; in one embodiment, the incoming line connector 31 is set at an angle of 44° to the plastic rear cover 3; in this way, it can be used on the side of the car body without additional wiring.
[0030] To further make the installation cavity A in a relatively sealed environment, a sealing ring is provided at the bottom of the metal front shell 2 to make the metal front shell 2 fit tightly with the metal rear cover 41. This prevents external factors such as dust and water vapor from affecting the operation of the circuit components.
[0031] Working principle: By combining the metal front shell 2 and the plastic back cover 3, a mounting cavity A is formed for the installation of the circuit board 5 and the heat-conducting component 4. On the one hand, the heat of the circuit board 5 is directly dissipated from the metal front shell 2, and on the other hand, the metal back cover 41 contacts with the thermal pad 42 to dissipate heat.
[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
