Description

Camera module

This embodiment relates to a camera module.

Recently, ultra-small camera modules have been developed and are widely used in small electronic products such as smartphones, laptops, and game consoles.

As automobiles become more popular, ultra-small cameras are widely used in vehicles as well as in small electronic products. For example, black box cameras for vehicle protection or objective data on traffic accidents, rear surveillance cameras that allow drivers to monitor the blind spots at the rear of the vehicle through a screen to ensure safety when reversing, and surrounding detection cameras that can monitor the surroundings of the vehicle are provided.

The camera may be equipped with a lens, a lens holder that accommodates the lens, an image sensor that converts an image of a subject captured by the lens into an electric signal, and a printed circuit board on which the image sensor is mounted. The housing forming the outer appearance of the camera is formed with a structure in which the entire area is sealed to prevent internal components from being contaminated by foreign substances containing moisture.

The present invention provides a camera module capable of firmly joining a plurality of bodies to each other and preventing misalignment between a lens and an image sensor during an assembly process.

A camera module according to the present embodiment comprises: a first body; a lens module coupled to the first body and including a lens; a second body coupled to a rear surface of the first body and including a hole; a substrate disposed within the second body; a connector coupled to a rear surface of the substrate; a connector body coupled to the hole and having at least a portion of the connector disposed inside; and a welding portion formed between the second body and the connector body.

The above hole may include a first hole and a second hole disposed below the first hole, a cross-sectional area of the second hole may be larger than the cross-sectional area of the first hole, and the connector body may include an upper portion coupled to the second hole.

The above welding portion can be formed between the outer surface of the upper plate and the inner surface of the second hole.

A gap is included that separates the outer surface of the upper plate and the inner surface of the second hole based on a direction perpendicular to the optical axis, and the gap can be arranged on the welding portion.

The above connector body may include a connector extraction portion having a pipe shape that protrudes downward from the lower surface of the upper plate and allows the connector to be placed on the inside.

A support guide having a shape that protrudes inwardly more than other areas may be arranged on the inner surface of the connector withdrawal portion.

A first inclined surface is formed at the lower end of the outer surface of the upper plate, a second inclined surface is formed at the lower end of the inner surface of the second hole, and the welding portion can be positioned between the first inclined surface and the second inclined surface.

A sloped surface having a shape in which the cross-sectional area of the first hole becomes smaller as it goes downward may be formed on the upper surface of the inner surface of the first hole.

The surface of the second body and the surface of the connector body each include a first region, which is a surface-treated region through anodizing, and a second region, which is a region that is not surface-treated, and the second region of the second body and the second region of the connector body can be arranged to face each other in the radial direction based on the welding portion.

The material of the first body, the second body and the connector body may be metal.

In this embodiment, since the connector body is attached to the rear of the second body by welding after the second body is attached to the rear of the first body with the optical axis between the lens and the image sensor aligned, there is an advantage in that the alignment between the lens and the image sensor can be prevented from being misaligned due to contact between the connector and the connector lead-out portion during the assembly process.

Due to the second guide, the space within the second body (200) may include a plurality of regions with different cross-sectional areas. For example, the cross-sectional area of the upper region of the space within the second body (200) where the second guide is not formed may be larger than the cross-sectional area of the lower region of the space within the second body (200) where the second guide is formed. The upper surface of the second guide may support the lower surface of the substrate of the substrate module (400) to be described later. The upper surface of the second guide may be in contact with the lower surface of the substrate.

As with the first body (100), at least a portion of the outer surface of the second body (200) may be surface treated. At least a portion of the outer surface of the second body (200) may be anodized.

The lenses (350) may be provided in multiple numbers and arranged to be spaced apart from each other along the optical axis direction within the barrel (310). The outermost lens among the multiple lenses (350) may be exposed above the camera module (10).

The barrel (310) may include a space with upper and lower surfaces open on the inside. The lens (350) may be placed in the space of the barrel (310). The barrel (310) may include a plurality of regions with different cross-sectional areas. For example, the region of the barrel (310) placed within the first body (100) may have a smaller cross-sectional area than the region of the barrel (310) protruding upward from the first body (100). The barrel (310) may have a circular cross-sectional shape.

The above barrel (310) may be made of metal.

The barrel (310) may include a flange (330). The flange (330) may be arranged on the outer surface of the barrel (310).

The lens module (300) may include a retainer (370) for guiding the outermost lens on the barrel (310).

The camera module (10) may include a substrate module (400). The substrate module (400) may be placed in a space within the camera module (10). The substrate module (400) may be placed between the first body (100) and the second body (200).

The substrate module (400) may include a substrate.

The substrate may be a printed circuit board (PCB). An image sensor (410, see FIG. 6) may be arranged on an upper surface of the substrate. The image sensor (410) may be arranged on the substrate so as to face the lens module (300) in the optical axis direction. The upper surface of the substrate may be supported by a lower surface of the first guide (170) of the first body (100), and the lower surface of the substrate may be supported by an upper surface of the second guide of the second body (200).

In this embodiment, the substrate is described as being composed of a single substrate, but this is not limited thereto, and the substrate may be provided in multiple numbers and arranged spaced apart from each other along the optical axis direction. In this case, the substrate module (400) may include a shield can supporting multiple substrates and a connecting substrate electrically connecting the multiple substrates. The connecting substrate may be a flexible printed circuit board (FPCB).

A connector (490) may be arranged on the lower surface of the substrate. The connector (490) may be soldered to the lower surface of the substrate. The connector (490) may have an upper end coupled to the lower surface of the substrate, and the other end extended downward so that at least a portion thereof may be arranged within a connector body (500) to be described later. An external terminal (not shown) is physically and electrically coupled to the connector (490), and accordingly, an electrical signal for driving the camera module (10) may be transmitted and received, or power may be provided to the camera module (10).

Below, the joint structure of the second body (200) and the connector body (500) will be described.

As shown in FIGS. 5 to 7, a hole through which a connector (490) passes may be formed on the rear surface of the second body (200). The hole may have a shape that passes through the lower surface from the upper surface of the lower plate (220) of the second body (200) in the direction of the optical axis. The hole may include a first hole (226) and a second hole (225) arranged below the first hole (226). The first hole (226) and the second hole (225) may be arranged adjacent to each other in the vertical direction.

The cross-sectional area of the first hole (226) and the cross-sectional area of the second hole (225) may be different from each other. The cross-sectional area of the first hole (226) may be smaller than the cross-sectional area of the second region (226). Based on the optical axis direction, the length of the first hole (226) may be smaller than the length of the second hole (225).

An inclined surface (227, see Fig. 7) having a shape in which the cross-sectional area of the first hole (226) becomes smaller as it goes downward may be formed on the upper surface of the inner surface of the first hole (226). Through the inclined surface (227), the coupling of the connector (490) to the inside of the hole can be easily guided.

The camera module (10) may include a connector body (500). The connector body (500) may be coupled to the lower surface of the second body (200). A connector (490) may be coupled to the connector body (500). An external terminal may be coupled to the connector body (500).

The connector body (500) may include an upper portion (510) and a connector withdrawal portion (550). The upper portion (510) and the connector withdrawal portion (550) may be formed as one body. The connector body (500) may be made of a metal material.

The upper plate (510) may form the upper end of the connector body (500). The upper plate (510) may have a ring-shaped cross-sectional shape. The upper plate (510) may have a circular cross-sectional shape. The cross-sectional area of the upper plate (510) may be formed to be smaller than the cross-sectional area of the second hole (225).

The upper plate (510) can be coupled to the second hole (225). When the upper plate (510) is coupled to the second body (200), the lower surface of the lower plate (220) can form the same plane as the lower surface of the upper plate (510).

A first inclined surface (530) may be formed on the lower side of the outer surface of the upper part (510) so that the distance to the inner surface of the second hole (225) increases as it goes downward. A second inclined surface (224) may be formed on the inner surface of the second hole (225) facing the first inclined surface (530) so that the distance to the outer surface of the upper part (510) increases as it goes downward. An arrangement area of a welded portion (600) to be described later may be secured by the first inclined surface (530) and the second inclined surface (224), and a welding process for forming the welded portion (600) may be performed more easily.

The connector withdrawal portion (550) may have a shape that protrudes downward from the lower surface of the upper plate (510). The connector withdrawal portion (550) may have a pipe shape with a hollow interior. The connector withdrawal portion (550) may be arranged at the center of the lower surface of the upper plate (5510).

A coupling guide (570) having a shape that protrudes outwardly compared to other areas may be formed on the outer surface of the connector withdrawal portion (550). An external terminal may be hook-coupled to the coupling guide (570), and accordingly, the coupling state of the external terminal and the connector body (500) may be firmly maintained.

On the outer surface of the connector withdrawal portion (550), a partition portion (560) is arranged on the outer side of the coupling guide (570) to partition the coupling area of the external terminal from other areas. A plurality of partition portions (560) may be provided, and a coupling guide (570) may be arranged between them.

At least a part of the connector (490) may be arranged inside the connector extraction portion (550). In order to guide the position of the connector (490) in the space inside the connector extraction portion (550), the connector body (500) may include a support guide (580, see FIG. 7) having a shape that protrudes inwardly from the inner surface of the connector extraction portion (550). The support guide (580) may have a ring-shaped cross-section. A hole through which the connector (490) passes may be formed on the inner surface of the support guide (580). A part of the inner surface of the support guide (590) may come into contact with the outer surface of the connector (490). The position of the connector (490) may be aligned within the connector extraction portion (550) through the support guide (590). At least a part of the connector (490) may be spaced apart in a direction perpendicular to the optical axis direction.

The connector body (500) can be joined to the second body (200) by welding. Accordingly, the camera module (10) can include a welding portion (600) for joining the second body (200) and the connector body (500). The welding portion (600) can be arranged between the lower plate (220) and the upper plate (510). The welding portion (600) can be arranged between the inner surface of the second hole (225) and the outer surface of the upper plate (510). As described above, the formation area of the welding portion (600) can be secured by the first inclined surface (530) and the second inclined surface (224).

Since the cross-sectional area of the upper part (510) is formed smaller than the cross-sectional area of the second hole (225), the welded part (660) can have an area with a different width in the direction perpendicular to the optical axis.

The area between the inner surface of the second hole (225) and the outer surface of the upper plate (510) can be divided into a plurality of regions. Some of the inner surface of the second hole (225) and the outer surface of the upper plate (510) can be joined to each other by the welding part (600), and other parts can be spaced apart in a direction perpendicular to the optical axis direction. A gap (g), which is an area spaced apart in a direction perpendicular to the optical axis direction, can be formed between the inner surface of the second hole (225) and the outer surface of the upper plate (510). The gap (g) can be arranged on the upper part of the welding part (600). The heat generated during the formation of the welding part (600) can be minimized from being transferred to the space within the camera module (10) through the gap (g).

The surface of the second body (200) and the surface of the connector body (500) may include a first region, which is a surface-treated region through anodizing, and a second region, which is a non-surface-treated region. Here, the second region may be a region where the material of the second body (200) and the connector body (500) is exposed to the outside through the outer surface. The formation region of the first region among the surface of the second body (200) or the surface of the connector body (500) may protrude outward more than the formation region of the second region.

In order to form the welded portion (600), as illustrated in FIG. 8, a portion of the lower surface of the lower plate (220) and a portion of the lower surface of the upper plate (510) may be second regions that have not been surface-treated through anodizing. Specifically, the second region of the lower plate (220) and the second region of the upper plate (510) may be arranged to face each other in the radial direction with respect to the welded portion (600), and the radial length of the second region of the lower plate (220) and the radial length of the second region of the upper plate (510) may be the same.

In the case of a conventional camera module in which the connector outlet is formed as one body with the second body, there was a problem in which the alignment between the image sensor and the lens was misaligned due to contact between the connector and the connector outlet during the process of joining the second body after joining the substrate to the rear of the first body.

However, according to the present embodiment, after the second body (200) excluding the connector body (500) is joined to the rear surface of the first body (100) with the optical axis between the lens (350) and the image sensor (410) aligned, the connector body (500) is joined to the rear surface of the second body (200) through post-processing welding, so there is an advantage in that the alignment state between the lens (350) and the image sensor (410) can be prevented from being misaligned due to contact between the connector (490) and the connector lead-out portion (550) during the assembly process.

In the above, even though all the components constituting the embodiments of the present invention have been described as being combined or operated in combination, the present invention is not necessarily limited to these embodiments. That is, within the scope of the purpose of the present invention, all of the components may be selectively combined and operated in one or more.
