Description

{APPARATUS OF DEHUMIDIFYING IN THE LAMP FOR VEHICLE}

The present invention relates to a dehumidifying device for a vehicle lamp, and more specifically, to a dehumidifying device for a vehicle lamp capable of mounting a dehumidifying agent in a vehicle lamp that has insufficient space to accommodate the dehumidifying agent, and facilitating replacement of the dehumidifying agent.

To ensure safe driving of vehicle drivers, vehicle lamps such as head lamps and rear lamps are installed at the front and rear of the vehicle.

The lamp housing accommodates a light source, a reflector, a control device, a power supply device, etc., inside, and the light irradiated by the light source is emitted to the outside of the vehicle through a transmitting portion provided in the lamp housing. If moisture enters the inside of the lamp housing due to various reasons such as temperature differences between the inside and outside of the vehicle lamp, weather changes, and changes in the driving environment, the visibility securing effect of the vehicle lamp is reduced, and this can cause serious problems in ensuring safety when driving the vehicle. Therefore, it is necessary to provide a desiccant to remove moisture inside the lamp housing.

Therefore, a method of installing a desiccant inside or outside a lamp housing has been widely used in the past. The conventional method of installing a desiccant inside a lamp housing fixes the desiccant to the inner surface of the lamp housing using a bracket, and forms a through hole in one surface of the bracket facing the desiccant so that the desiccant can come into contact with the air inside the lamp housing. On the other hand, the conventional method of installing a desiccant outside the lamp housing fixes the desiccant to the outer surface of the lamp housing using a bracket, installs a cover that covers the desiccant and the bracket to prevent the desiccant from coming into contact with the air outside the lamp housing, and forms a through hole in one surface of the lamp housing facing the desiccant so that the desiccant can come into contact only with the air inside the lamp housing.

However, according to the conventional technology described above, there are cases where space for accommodating a desiccant is not secured due to the size or mounting of components in the vehicle lamp.

Accordingly, in vehicle lamps where it is not easy to secure space to accommodate a desiccant, there is a need for a desiccant device for vehicle lamps that can accommodate a desiccant and facilitate replacement of the desiccant.

Referring to FIGS. 1 to 4, a dehumidifying device (100) for a vehicle lamp according to the present invention may include a lamp housing (110), a sealing member (120), a dehumidifying member (130), and a supporting member (140).

The lamp housing (110) may be provided to accommodate at least one light source, such as an LED, and components capable of emitting light emitted from the light source, inside thereof. The rear surface of the lamp housing (110) faces the vehicle body, and a sealing protrusion (111) may be provided therebetween so that a sealing member (120) in the form of a gasket, pad, or the like may be mounted therebetween.

The above sealing projection (111) protrudes in the direction of the vehicle body along the periphery of the rear surface of the lamp housing (110) and may have a closed loop shape. In addition, the sealing member (120) described below may be provided so as to be tightly coupled to the sealing projection (111).

A path (115) of a wire or connector for electrical connection between the inside of the lamp housing (110) and the vehicle body may be formed on the rear side of the lamp housing (110). The rear side of the lamp housing (110) may be divided into an inner region and an outer region centered on the sealing protrusion (111), and the path (115) of the wire or connector may be positioned in the inner region centered on the sealing protrusion (111).

In addition, a ventilation hole (112) may be formed on the rear of the lamp housing (110) to communicate the inside of the lamp housing (110) with the outside to maintain the internal humidity of the lamp housing (110) or remove moisture.

As described above, the rear surface of the lamp housing (110) can be divided into an inner region and an outer region centered on the sealing protrusion (111), and the ventilation hole (112) can be located in the inner region.

Specifically, in the present invention, the ventilation hole (112) is positioned in the inner region toward the rear of the lamp housing (110), and is configured as an example of a lower region, specifically, a lower corner side. Accordingly, the dehumidifying member (130) that covers the ventilation hole (112) and is mounted can be prevented from being deformed or detached by being bent downward in a settled state. The formation position of the ventilation hole (112) of the present invention is not limited thereto, and any position that can effectively control or remove humidity or moisture inside the lamp housing (110) can be modified or changed.

A space is formed around the above-mentioned ventilation hole (112) in which a dehumidifying member (130) described later is installed, and a support member (140) may be provided to support the dehumidifying member (130) and prevent movement.

The above-mentioned support member (140) may be provided to form a settling space (S) for the dehumidifying member (130) between the rear surface of the lamp housing (110) and the sealing member (120) and may be provided to be coupled to each other.

In addition, both ends of the support rib are provided to be connected to the sealing member (120) to have a closed loop shape, and the ventilation hole (112) may be positioned on the inside thereof, for example.

In addition, the shape of the support rib may have various forms depending on the shape combined with the sealing member (120). Examples of this can be specifically described later with reference to FIGS. 6 to 8.

In addition, in the present invention, the support member (140) is described as having a closed loop shape formed by connecting its end to the sealing projection (111), but is not limited thereto. For example, the support member (140) may be formed in a closed loop shape around the ventilation hole (112) alone without being connected to the sealing projection (111).

The above support member (140) is described as having a structure that is a separate structure from the lamp housing (110) and is coupled to the lamp housing (110), but is not limited thereto. For example, the support rib may be formed integrally with at least one of the lamp housing (110) or the sealing protrusion (111). Specifically, the support rib may be formed together with the lamp housing (110) during molding. In addition, when the sealing protrusion (111) is formed integrally with the lamp housing (110), the support rib may be formed integrally with the lamp housing (110) and the sealing protrusion (111). In addition, when the sealing projection (111) is formed separately from the lamp housing (110) and is provided on the lamp housing (110), the support rib may be formed integrally with the sealing projection (111) and provided on the lamp housing (110). In addition, the support rib may be formed as a completely separate configuration from the lamp housing (110) and the sealing projection (111) and provided on the mounting position on the rear of the lamp housing (110).

As described above, the mounting space (S) for mounting the dehumidifying member (130) centered on the ventilation hole (112) can form a closed loop shape due to the support member (140) or the support member (140) and the sealing protrusion (111), and the dehumidifying member (130) can be mounted in the mounting space (S) of the closed loop shape.

The sealing member (120) may be provided to have a predetermined width along the rear periphery of the lamp housing (110) and to be closely coupled to the sealing projection (111). In addition, the sealing member (120) may be provided to cover the lower rear area of the lamp housing (110) where the ventilation hole (112) is located. The sealing member (120) may be formed by including a configuration such as a gasket or a pad. In addition, the sealing member (120) may be formed by a pad having elasticity that is condensed at the same time as the lamp housing (110) and the body are coupled.

In addition, the support member (140) may be formed as a single protruding projection-shaped support rib (140a) so as to be interlocked with and fixed to the outer circumference of the sealing member (120) at the rear of the lamp housing (110).

In addition, the connecting portion (121) provided in the sealing member (120) may form a groove structure (121a) that is concavely inserted to engage with the protrusion (111a).

Accordingly, when the sealing member (120) is coupled to the rear surface of the lamp housing (110), the support rib (140a) is fixed tightly by engaging with the groove structure (121a), and the outer peripheral surface of the sealing member (120) can be fixed tightly by engaging with the side surface of the support rib (140a). In addition, the dehumidifying member (130) can be mounted tightly in the mounting space (S) formed between the ventilation hole (112) and the sealing member (120).

In addition, referring to FIG. 8 among FIGS. 7 to 9, the sealing projection (111) may be formed in a closed loop shape with a first protruding portion (111b) having two protrusions protruding in a parallel 'W' shape. In addition, the support member (140) may be formed on the rear surface of the lamp housing (110) as a support rib (140b) protruding toward the sealing member (120).

In addition, the connecting portion (121) provided on the sealing member (120) may be provided with a second protrusion (121b) having two protrusions protruding in an 'M' shape to engage with the first protrusion (111b). In addition, a concave-shaped fixing groove (121c) may be formed at the end of the sealing member (120) so that the supporting rib (140b) protruding toward the end of the sealing member (120) may be inserted to allow for close coupling.

Accordingly, when the sealing member (120) is coupled to the rear of the lamp housing (110), the first protruding portion (111b) can be tightly coupled by interlocking with the second protruding portion (121b), and the support rib (140b) can be tightly fixed by interlocking with the mounting groove (121c). In addition, the dehumidifying member (130) can be tightly mounted in the mounting space (S) formed between the ventilation hole (112) and the sealing member (120).

In addition, referring to FIG. 9 among FIGS. 7 to 9, the sealing projection (111) may be formed in a closed loop shape with a first protruding portion (111b) having two protrusions protruding in a parallel 'W' shape. In addition, the support member (140) may be formed on the rear surface of the lamp housing (110) as a support rib (140c) protruding in a 'W' shape toward the sealing member (120).

In addition, the connecting portion (121) provided in the sealing member (120) may be provided with a second protruding portion (121b) having two protrusions protruding in an ‘M’ shape to engage with the first protruding portion (111b).

In addition, an 'M'-shaped protrusion (121d) can be formed at the end of the sealing member (120) so that the support rib (140c) protruding in a 'W' shape toward the end of the sealing member (120) can be inserted to enable close bonding.
