Abstract
The utility model discloses a kind of vehicle-mounted camera, including lens housing, its rear end is equipped with a mounting groove, is equipped with groove on the inside of the notch of mounting groove；The camera lens that circuit substrate is fixed in the mounting groove, and is right against in the lens housing；Back casing is welded in the groove by package sealing with laser formula.The vehicle-mounted camera of the utility model, front and rear casing is welded, is not required to increase additional waterproof part, thoroughly completely cuts off outside moisture and enters body interior；Metal shell constantly passes the heat in mould group to greatest extent.
Description
Technical Field
The utility model relates to a fields such as camera specifically are an on-vehicle camera.
Background
A CAMERA (CAMERA or WEBCAM), also known as a computer CAMERA, a computer eye, an electronic eye, etc., is a video input device, and is widely used in video conferences, telemedicine, real-time monitoring, etc. Common people can also have image and voice conversations and communications with each other through the camera in the network. In addition, people can also use the method for various popular digital images, video and audio processing and the like.
The mounting structure of camera has a lot of, and in on-vehicle camera, waterproof, heat dissipation are two big difficult problems of on-vehicle high definition digtal camera. In the prior art, heat dissipation and water resistance are mainly performed by the following modes and structures: the other is that the rear shell and the front shell are connected through screws and locked with compression gaskets to realize the waterproof of the front shell and the rear shell. The rear shell extrudes the inner shell, the inner shell extrudes the lens, and the lens and the front shell extrude the O-shaped ring to realize that the front shell and the lens are waterproof. Therefore, the heat dissipation mode of the structure is as follows: the heat generated by the circuit board can only be slowly conducted to the outside by the plastic part. It has obvious drawbacks: the gasket is easily deformed during assembly, resulting in water-proof failure. The heat dissipation is slow, the image noise is serious when the temperature rise is too high, and decoking occurs. The other method is ultrasonic welding of the back shell and the front shell lens, and the plastic part is heated and melted through mechanical vibration, so that the two parts are welded together. However, vibration may damage electronic components on the circuit board during soldering. The heat dissipation is slow, the image noise is serious when the temperature rise is too high, and decoking occurs.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the utility model provides a vehicle-mounted camera to solve at least one technical problem among the prior art.
The technical scheme for realizing the purpose is as follows: a vehicle-mounted camera comprises a lens shell, wherein the rear end of the lens shell is provided with a mounting groove, and a groove is formed in the inner side of a notch of the mounting groove; the circuit substrate is fixed in the mounting groove and is right opposite to the lens in the lens shell; and the rear shell is welded in the groove in a laser sealing mode.
Furthermore, the circuit substrate is fixed in the mounting groove through screws.
Furthermore, the rear shell and the lens shell are metal shells.
Further, a heat conduction protection member is arranged between the circuit substrate and the rear shell.
Furthermore, the protection part comprises an upright post arranged on one surface of the rear shell facing the circuit substrate, and an elastic ring sleeved at the front end of the upright post and pressed between the upright post and the circuit substrate.
The utility model has the advantages that: the front shell and the rear shell of the vehicle-mounted camera of the utility model are welded into a whole, so that no extra waterproof part is needed to be added, and external moisture is thoroughly isolated from entering the body; the metal shell transfers the heat in the module to the maximum extent.
Drawings
The invention is further explained below with reference to the figures and examples.
Fig. 1 is a schematic structural diagram of an on-vehicle camera according to an embodiment of the present invention.
Wherein,
1 a lens housing; 2 a circuit board;
3 a rear housing; 11, mounting a groove;
12, grooves; 31 upright posts;
32 elastic ring.
Detailed Description
The following description of the embodiments refers to the accompanying drawings for illustrating the specific embodiments in which the invention may be practiced. In the present invention, directional terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc. refer to directions of the attached drawings only. Accordingly, the directional terms used are used for describing and understanding the present invention, and are not used for limiting the present invention.
Example (b): as shown in fig. 1, a vehicle-mounted camera includes a lens housing 1, a circuit board 2, and a rear housing 3.
Wherein, the rear end of the lens shell 1 is provided with a mounting groove 11, and the inner side of the notch of the mounting groove 11 is provided with a groove 12. The rear housing 3 is welded in said groove 12 by laser sealing.
The circuit substrate 2 is fixed in the mounting groove 11 by screws and is right opposite to the lens in the lens shell 1; the rear shell 3 and the lens shell 1 are metal shells, and heat dissipation is facilitated.
A guard member is provided between the circuit substrate 2 and the rear case 3. The guard member includes a post 31 and an elastic ring 32, and is disposed on one surface of the rear housing 3 facing the circuit board 2, and the elastic ring 32 is sleeved on a front end of the post 31 and is pressed between the post 31 and the circuit board 2.
The rear shell 3 and the lens shell 1 are welded at the position using laser, so that air is completely isolated, and the aim of water prevention is fulfilled. The heat generated by the circuit substrate 2 is conducted to the metal front shell, and then is dissipated, so that the purpose of reducing the internal temperature is achieved.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
