Description
Technical Field
The present invention relates to a lamp module for a vehicle, and more particularly, to a lamp module for a vehicle that enables a driver or a passenger to control a light source for illuminating the interior of the vehicle through a simple touch operation.
Background
Generally, a vehicle is provided with a storage device, such as a glove box or a console box, for storing various items, and a room lamp for illuminating the interior of the vehicle.
That is, various convenience devices are installed in a vehicle to provide convenience and comfort to a passenger of the vehicle.
Regarding a handy device for a vehicle, patent document 1 discloses an interior lamp for a vehicle, which includes: a front case in which at least one lens for diffusing light, a switch provided with a lamp, and a board receiving power from a vehicle to drive the lamp in response to an operation of the switch are installed; and a rear case connected to a rear side of the front case. A long slide hole is formed in a bottom surface of the front case in a longitudinal direction of the front case, and the switch is operated in a sliding manner. The lamp panel is mounted on the upper side of the sliding housing below the contact end of the panel, and a lamp connected to the lamp panel is exposed to the lower surface of the sliding housing. The knob is mounted on a lower surface of one side of the slide case so as to be exposed to the inside of the vehicle through the slide hole. The plate is provided with a first end with which the contact end is in contact for turning on the lamp so as to illuminate a right area of the vehicle interior in an off state of the lamp; a second end with which the contact terminal contacts to turn on the lamp so that the lamp is turned on and off when the door is opened and closed; a third terminal to which the contact terminal is contacted to turn on a lamp so as to illuminate a central area of the vehicle interior; and a fourth end with which the contact end is contacted to turn on the light to illuminate a left area of the vehicle interior. The first to fourth ends are disposed to be spaced apart from each other. In a state where the lamp is turned off, if the contact terminal is selectively contacted with the first, third and fourth terminals through the slide switch, the lamp selectively illuminates a right area, a center area and a left area of the interior of the vehicle. In a state where the lamp is turned off, if the contact terminal is in contact with the second terminal through the slide switch, the lamp is turned on when the door is opened, and the lamp is turned off when the door is closed.
However, in the interior lamp for a vehicle disclosed in patent document 1, in order to illuminate the interior of the vehicle, the switch needs to be slid so that the contact terminals selectively contact each of the first, third, and fourth terminals of the panel.
That is, there is inconvenience in that the driver or passenger needs to operate the switch with the finger to control the lamp.

Hereinafter, the operation and effect of the present invention configured as described above will be described.
As shown in fig. 1 to 7, in a lamp module 100 for a vehicle according to an embodiment of the present invention, an illumination lens 30 is mounted in a first assembly hole 11 in a cover 10, and a main body 41 of a rear cover 40 is mounted in the cover 10.
The first and second fitting holes 51b and 61b in the first and second touch sensing units 50 and 60 are engaged with the first and second fitting protrusions 43 and 44 of the rear cover 40 in a fitting manner.
Here, the protruding portion 42 is inserted into the first and second insertion spaces 51a and 61a in the first and second touch sensing electrode bodies 51 and 61, and the second touch sensing electrode body 61 is positioned between the protruding portion 42 and the first touch sensing electrode body 51 and inserted into the first insertion space 51 a.
Subsequently, the diffusion lens 31 is mounted in the second assembly hole 42a in the rear cover 40, and the control board 70 is mounted on the main body 41 of the rear cover 40.
Here, the first and second connection terminals 51c and 61c of the first and second touch sensing units 50 and 60 are fitted into the first and second connection holes 72 and 73 in the control board 70, whereby the first and second touch sensing units 50 and 60 are electrically connected to the control board 70.
Subsequently, the cover 10 and the housing 20 are connected to each other.
The diffusion lens 31, the first and second touch sensing units 50 and 60, and the control board 70 are mounted to the rear cover 40, and the rear cover 40 is accommodated in the inner space 21 of the case 20.
Subsequently, the lamp module 100 for a vehicle is installed in the interior of the vehicle, and the control board 70 is electrically connected to the power supply unit and the control unit of the vehicle.
As shown in fig. 6(a), 6(b) and 7, the control board 70 applies a voltage to the first and second touch sensing electrode bodies 51 and 61 of the first and second touch sensing units 50 and 60 through the first and second connection terminals 51c and 61c fitted in the first and second connection holes 72 and 73.
Here, a higher voltage is applied to the second touch sensing electrode body 61 than to the first touch sensing electrode body 51.
An electric field is generated around the first touch sensing electrode body 51 to which a voltage is applied, and thus a first touch sensing area a1 capable of sensing a change in capacitance of the first touch sensing electrode body 51 is formed at a peripheral area of the first assembly hole 11 and a peripheral portion of the illumination lens 30.
Further, an electric field is generated around the second touch sensing electrode body 61 to which a voltage is applied, and thus a second touch sensing area a2 capable of sensing a change in capacitance of the second touch sensing electrode body 61 is formed in the peripheral area of the first assembly hole 11 and the entire portion of the illumination lens 30.
Here, the second touch sensing area a2 is formed to be wider than the first touch sensing area a 1.
Therefore, as shown in fig. 6(a) and 6(b), a human body such as a finger of a driver or a finger of a passenger may approach and contact the central portion of the illumination lens 30 instead of the peripheral region of the first assembly hole 11 in the cover 10 and the peripheral portion of the illumination lens 30.
Here, the finger of the driver or the finger of the passenger is located only within the second touch sensing area a 2.
Since the human body located in the second touch sensing area a2 is conductive, the capacitance of the second touch sensing electrode body 61 changes.
That is, the second touch sensing unit 60 senses the approach and contact of the human body to the center portion of the illumination lens 30.
The control board 70 detects a capacitance change of the second touch sensing electrode body 61 through the second connection terminal 61c of the second touch sensing electrode body 61, and determines the capacitance change as a control signal. When the light source 71 is in the off state, the control board 70 performs control such that the light source 71 is turned on.
Accordingly, the light source 71 emits light, and the light from the light source 71 is diffused by the diffusion lens 31 installed in the second assembly hole 42a and sequentially passes through the through hole 41a and the illumination lens 30 installed in the first assembly hole 11.
As a result, the vehicle interior is illuminated.
Thereafter, a human body such as a finger of a driver or a finger of a passenger may approach and contact the central portion of the illumination lens 30 again.
At this time, the control board 70 detects a change in capacitance of the second touch sensing electrode body 61 through the second connection terminal 61c of the second touch sensing electrode body 61, and determines the change in capacitance as a control signal. When the light source 71 is in the on state, the control board 70 performs control such that the light source 71 is turned off.
As a result, the vehicle interior is not illuminated.
As shown in fig. 7, a human body, for example, a finger of a driver or a finger of a passenger may approach and contact a peripheral area of the first assembly hole 11 and a peripheral portion of the illumination lens 30 in the cover 10, instead of the central portion of the illumination lens 30.
Here, the finger of the driver or the finger of the passenger is located within the first touch-sensitive area a1 and the second touch-sensitive area a 2.
Since the human body located in the first and second touch sensing areas a1 and a2 is conductive, the capacitance of each of the first and second touch sensing electrode bodies 51 and 61 is changed.
That is, the first and second touch sensing units 50 and 60 sense the approach and contact of a human body to the peripheral area of the first assembly hole 11 and the peripheral portion of the illumination lens 30.
The control board 70 simultaneously detects the capacitance changes of the first touch sensing electrode body 51 and the second touch sensing electrode body 61 through the first connection terminal 51c and the second connection terminal 61c of the first touch sensing electrode body 51 and the second touch sensing electrode body 61, and determines the capacitance changes as a control cancellation signal. Therefore, the control board 70 does not control the light source 71.
As a result, the vehicle interior is maintained in an illuminated state or a non-illuminated state.
As apparent from the above description, according to the present invention, when only the second touch sensing unit senses that a human body approaches and contacts the central portion of the illumination lens, the control board controls the light source such that the light source is turned on or off.
In addition, the control board does not control the light source when the first and second touch sensing units sense that a human body approaches and contacts the peripheral area of the first assembly hole in the cover and the peripheral portion of the illumination lens.
That is, the peripheral area of the first assembly hole in the cover and the peripheral portion of the illumination lens are clearly defined as portions where light source control is impossible, and the central portion of the illumination lens is clearly defined as a light source control portion.
In other words, the driver or passenger can control the light source to illuminate the interior of the vehicle by a simple finger touch operation.
Since the diffusion lens is spaced apart from the illumination lens by a predetermined distance by the protruding portion of the rear cover, diffusion of light from the light source may be further increased.
That is, a wider area of the vehicle interior can be illuminated.
According to the present invention, the first and second fitting holes in the first and second touch sensing units are engaged with the first and second fitting protrusions of the rear cover in a fitting manner.
That is, it is not necessary to bond or adhere the first and second touch sensing units to the rear cover using an adhesive material or a bonding material.
In addition, the protruding portion of the rear cover is inserted into the first and second insertion spaces in the bodies of the first and second touch sensing electrodes, and thus the bodies of the first and second touch sensing electrodes do not block light emitted from the light source.
That is, light from the light source is easily diffused by the illumination lens.
Since the main body of the second touch sensing electrode is positioned between the protruding portion of the rear cover and the main body of the first touch sensing electrode, the installation positions of the first touch sensing unit and the second touch sensing unit can be accurately recognized.
That is, the first touch sensing unit and the second touch sensing unit can be easily installed or replaced while being distinguished from each other.
Since the first and second connection terminals of the main bodies of the first and second touch sensing electrodes are fitted in the first and second connection holes in the control board, the first and second touch sensing units between the rear cover and the control board can be easily installed or replaced.
In addition, the first and second touch sensing units are stably supported by the rear cover and the control board.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
