In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
Referring to fig. 1-9, the present invention relates to an indicator light assembly for an automobile instrument desk, which is particularly applied to an electronic device to indicate the working state of the electronic device, such as a mobile phone charging device, and the indicator light assembly can only indicate the charging state of the mobile phone charging device, such as charging or full charging; the indicating lamp assembly specifically comprises a mounting panel 1 and a back shell 2 which are mutually covered, a circuit board 3 and an indicating light-transmitting piece 4; for the specific electronic equipment to which the indicating lamp assembly is applied, the mounting panel 1 is a panel of the electronic equipment, when the electronic equipment is mounted on an automobile instrument desk, the front surface of the mounting panel 1 can be directly seen from a main driving position, and the mounting panel 1 can be flush with the surface of the instrument desk or lower than or higher than the surface of the instrument desk; in a specific embodiment, the electronic device may be located in close proximity to the dashboard or central control panel, and the mounting panel 1 is preferably flush with the display surface of the dashboard or central control panel in close proximity thereto, but may be above or below the display surface of the dashboard or central control panel.
The installation panel 1 is provided with a hollow indication window 13.
The circuit board 3 is mounted with an indicator lamp 31, the circuit board 3 is mounted on the back of the mounting panel 1 and avoids the indicator window 13 (shown in fig. 8), and the indicator lamp 31 is located on the side far away from the mounting panel 1.
The indication light-transmitting member 4 is mounted on the mounting panel 1, and the indication light-transmitting member 4 closes the indication window 13, and the indication light-transmitting member 4 is arranged side by side with the indication lamp 31 (shown in fig. 2).
The back shell 2 covers the circuit board 3 and indicates light transmission piece 4, the back shell 2 includes the light reflecting structure, the light reflecting structure includes along indicating light transmission piece 4 and the first reflector 21 and the second reflector 22 that the side by side direction of indicating lamp 31 was arranged and is connected, be equipped with the first plane of reflection 201 towards indicating lamp 31 on the first reflector 21, be equipped with the second plane of reflection 202 towards indicating window 13 on the second reflector 22, in the side by side direction, first plane of reflection 201 is to the one side slope that is close to mounting panel 1, the second plane of reflection 202 is to the one side slope of keeping away from mounting panel 1, so that the light that the pilot lamp 31 sent can be followed indicating window 13 through indicating light transmission piece 4 after at least one of first plane of reflection 201 and second plane of reflection 202 reflects.
In the prior art, the indicator lamp 31 mostly adopts an LED, and the light of the LED is strong, so that the LED cannot be directly arranged at the indication window 13, and the indication light-transmitting member 4 needs to be arranged at the indication window 13 to reduce the light intensity and play a role of light uniformization; in addition, the indicator light assembly can generally indicate a plurality of colors, so a plurality of indicator lights 31 with different colors are required to be installed on the circuit board 3, and the light of the indicator lights 31 can all irradiate the indicator light-transmitting member 4, so the circuit board 3 is generally installed on the back shell, a certain interval is left between the circuit board 3 and the installation panel 1, and the indicator lights 31 are installed on the surface of the circuit board 3 facing the installation panel 1, so that any one indicator light 31 can irradiate the indicator light-transmitting member 4 through the interval after being lighted. But the space occupied by the indicator light assembly is significantly increased due to the presence of the space.
For convenience of description, in the present invention, the outward facing side of the mounting panel 1 and the circuit board 3 is a front side, and the opposite side is a back side, so that the front side of the circuit board 3 faces the back side of the mounting panel 1, and the side of the circuit board 3 away from the mounting panel 1 is the back side of the circuit board 3.
The circuit board 3 is wholly parallel to the installation panel 1, and the indicator lamp 31 is installed on the back surface of the circuit board 3, so that the indicator lamp 31 can emit light towards one side far away from the installation panel 1, the circuit board 3 and the installation panel 1 do not need to keep the interval, the circuit board 3 can be tightly attached to the installation panel 1, and the circuit board 3 and the installation panel 1 can be more compact; the circuit board 3 avoids the indication window 13, so the circuit board 3 does not block the indication light-transmitting member 4, the indication lamp 31 and the indication light-transmitting member 4 are arranged side by side, the first light-reflecting plane 201 of the light-reflecting structure faces the indication lamp 31, and the second light-reflecting plane 202 faces the indication window 13, so that most of light emitted by the indication lamp 31 irradiates the first light-reflecting plane 201, and part of light is reflected to the second light-reflecting plane 202 through reflection of the first light-reflecting plane 201 and irradiates the indication light-transmitting member 4 through reflection of the second light-reflecting plane 202, so that the light can be emitted from the light-transmitting member; certainly, in the above processes, a part of light emitted by the indicator light 31 can directly irradiate on the second light reflecting plane 202, and then directly reflect to the position of the indicating light-transmitting member 4, and there is also a part of light which directly irradiates on the position of the indicating light-transmitting member 4 after being reflected by the first light reflecting plane 201, and there is also a part of light which is reflected for many times by the inner side surfaces of the light reflecting structure (the first light reflecting plane 201 and the second light reflecting plane 202 both belong to the inner side surfaces), and finally irradiates on the position of the indicating light-transmitting member 4, however, most of the light emitted by the indicator light 31 is reflected by the inner side surface of the light reflecting structure, and finally irradiates on the indicating light-transmitting member 4, thereby ensuring that the specific working state of the electronic device can be effectively indicated. The invention utilizes the original back shell to reflect the light emitted by the indicator lamp 31, so that the direction of the light is changed by 180 degrees, and finally the light is emitted from the indicating light-transmitting part 4; in addition, in the invention, the circuit board 3 is directly installed on the back of the installation panel 1, the back shell 2 is covered with the installation panel 1, therefore, the circuit board 3 is positioned in the space enclosed by the installation panel 1 and the cover plate, when in assembly, the circuit board 3 can be firstly connected with the installation panel 1, then the back shell 2 is covered with the installation panel 1, and the two are connected, when in disassembly, the back shell 2 can be firstly separated from the installation panel 1, and then the circuit board 3 is separated from the installation panel 1, thus, no matter the indication lamp assembly is assembled or disassembled, the assembly and disassembly of any one part in the indication lamp assembly can not influence other parts, so that an ordinary user can independently assemble and disassemble the indication lamp assembly, thereby being convenient for after sale.
The back shell 2 and the back cover of the installation panel 1 are covered and fixedly connected with each other, and the connection mode between the back shell and the installation panel can be at least one of bonding, clamping and screw connection. Preferably a combination of snap and screw connections are used so that the back shell 2 can be detachably connected to the mounting panel 1.
Referring to fig. 5, the first reflector 21 and the second reflector 22 may be of a plate-like structure or other structures, preferably, of a plate-like structure, the inner side of the first reflector 21 and the inner side of the second reflector 22 are both flat surfaces and both face one side of the circuit board 3, or the inner side of the first reflector 21 and the inner side of the second reflector 22 are both respective front surfaces, because the first reflector 21 and the second reflector 22 are both located on the back side of the circuit board 3, so that the inner sides of the first reflector and the second reflector face one side of the circuit board 3, wherein the inner side of the first reflector 21 is a first reflective plane 201, the inner side of the second reflector 22 is a second reflective plane 202, the first reflective plane 201 faces the indicator 31 specifically, so that light emitted by the indicator 31 can substantially all irradiate onto the first reflective plane 201, the first reflective plane 201 has an angle with the surface where the installation panel 1 is located, and specifically, in a direction from the indicator light-transmitting member 4 to the indicator 31, the first reflective plane 201 is inclined toward the side of the installation panel 1, so that light emitted by the indicator 31 passes through the first reflective plane 201 and then irradiates onto the indicator light-transmitting member 4; the second light reflecting plane 202 faces the indication light transmitting member 4, the second light reflecting plane 202 also has an angle with a surface where the installation panel 1 is located, specifically, in a direction from the indication light transmitting member 4 to the indication lamp 31, the second light reflecting plane 202 inclines to a side away from the installation panel 1, in a thickness direction of the installation panel 1, the first light reflecting plane 201 and the second light reflecting plane 202 are at least partially overlapped, so that part of light reflected by the first light reflecting plane 201 can irradiate the second light reflecting plane 202, and the light is reflected by the second light reflecting plane 202 and irradiates the indication light transmitting member 4, so that the indication light transmitting member 4 can emit light outwards.
It should be emphasized that the light reflected by the first light reflecting plane 201 is emitted to one side of the light transmissive indicator 4, and since the light emitted by the indicator 31 has a certain divergence angle, a part of the light reflected by the first light reflecting plane 201 directly irradiates the light transmissive indicator 4 (this part of the light is called a first light), a part of the light is reflected to the second light reflecting plane 202 and reflected to the light transmissive indicator 4 via the second light reflecting plane 202 (this part of the light is called a second light), and the rest of the light is reflected to the circuit board 3 or the mounting panel 1, and is reflected to the light transmissive indicator via multiple reflections of the circuit board 3, the mounting panel 1 and the light reflective structure (this part of the light is called a third light); most of the light emitted from the indicator lamp 31 reaches the indicator light-transmitting member 4 along the paths of the first light and the second light, that is, most of the light emitted from the indicator lamp 31 can be reflected once or twice to irradiate the indicator light-transmitting member 4, so as to reduce the loss caused by the reflection of the light and ensure the brightness of the indicator light-transmitting member 4.
Further, an included angle between the first light reflecting plane 201 and the plane where the mounting panel 1 is located is preferably smaller than 45 °, so that after the light emitted by the indicator lamp 31 is reflected by the first light reflecting plane 201, most of the light irradiates the indicating light-transmitting member 4, the proportion that the light irradiates the indicating light-transmitting member 4 after being reflected once (the first light) is enlarged, and the brightness of the indicating light-transmitting member 4 is improved.
The angle between the first light reflecting plane 201 and the plane of the mounting panel 1 (hereinafter referred to as the first angle) may be 18 ° to 45 °, for example, 18 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, etc.
For example, the angle between the first light reflecting plane 201 and the plane of the installation panel 1 is 20 °, and the indicator light 31 irradiates the first light reflecting plane 201 along the normal direction of the installation panel 1, and after being reflected by the first light reflecting plane 201, the indicator light-transmitting member 4 on one side can be directly irradiated.
Of course, the angle between the second light reflecting plane 202 and the plane of the mounting panel 1 (hereinafter referred to as the second angle) may be 30-60 °, such as 30 °, 35 °, 40 °, 45 °, 50 °, 55 ° or 60 °, and the like, in the side-by-side direction, the size of the indicator lamp 31 is larger than that of the light transmitting member 4 (a plurality of indicator lamps 31 are arranged side by side, as will be described later), and the second angle is larger than the first angle, so that the first light reflecting plane 201 covers a larger range than the second light reflecting plane 202 (the area of the projection of the first light reflecting plane 201 is larger than that of the second light reflecting plane 202 in the projection on the plane of the mounting panel 1), and the second light reflecting plane 202 can reflect the light irradiated thereon to the light transmitting member 4.
In addition, one end of the first reflector 21 close to the indication light-transmitting member 4 and one end of the second reflector 22 close to the indicator 31 are connected with each other, so that the first reflective surface is connected with the second reflective surface, and an included angle is formed between the first reflective plane 201 and the second reflective plane 202, wherein the included angle is preferably an obtuse angle, so that in the thickness direction, the reflective structure is more flat, and the space occupied by the indicator light assembly is reduced.
Through the arrangement, 70% -80% of the light emitted by the indicator lamp 31 can be the first light and the second light, so that the brightness of the indication light-transmitting member 4 is ensured.
Moreover, the first reflective plane 201 and the second reflective plane 202 are both mirror surfaces, that is, after light irradiates on the two reflective planes, mirror reflection occurs, so as to reduce scattering loss of light, so that more light can irradiate on the position of the indication translucent member 4, thereby ensuring the brightness of the indication translucent member 4.
Preferably, referring to fig. 5, the indicator lamp 31 protrudes from the back surface of the circuit board 3.
The light reflecting structure further comprises a first side plate 23, the first side plate 23 is parallel to the normal direction of the installation panel 1, one end of the first side plate 23 is connected to one end of the first reflection plate 21, which is far away from the second reflection plate 22, the other end of the first side plate 23 is abutted to the installation panel 1, and the indication lamp 31 is further far away from the installation panel 1 compared with one end of the first reflection plate 21, which is connected to the first side plate 23, in the normal direction.
The first side plate 23 is arranged, so that the first light reflecting plate 21 is abutted to the mounting panel 1 through the first side plate 23, that is, the distance between the first light reflecting plate 21 and the mounting panel 1 is increased; moreover, because the indicator lamp 31 protrudes from the back of the circuit board 3, and the end of the first reflector 21 connected to the first side plate 23 is farther away from the installation panel 1 than the indicator lamp 31, so that any position on the first reflector 21 is farther away from the reflector panel than the indicator lamp 31, that is, when the back shell 2 is connected to the installation panel 1, the first reflector 21 cannot touch the protruding indicator lamp 31 at all, and the safety of the indicator lamp assembly in the assembling and disassembling process is improved.
Of course, the reflective structure may not include the aforementioned first side plate 23, and in this case, the end of the first reflective plate 21 away from the second reflective plate 22 abuts against the mounting panel 1.
Further, referring to fig. 4 and 6, the light reflecting structure further includes a second side plate 24 and a third side plate 25 which are oppositely disposed, the second side plate 24 and the third side plate 25 extend along a direction parallel to the normal direction and a side-by-side direction, the second side plate 24 and the third side plate 25 are respectively located at two sides of the indicator lamp 31 perpendicular to the side-by-side direction, and are connected with the first side plate 23, the first light reflecting plate 21 and the second light reflecting plate 22 and abut against the installation panel 1, and the first side plate 23, the second side plate 24, the third side plate 25, the first light reflecting plate 21, the second light reflecting plate 22 and the installation panel 1 jointly enclose a relatively closed space.
The light reflecting structure is composed of a first side plate 23, a second side plate 24, a third side plate 25, a first light reflecting plate 21 and a second light reflecting plate 22, so that a space surrounded by the light reflecting structure is only opened towards the front, when the back shell 2 is covered on the display panel, the back of the display panel basically seals the opening, so that a relatively closed space is formed, the indicator lamp 31 is located in the closed space, therefore, light emitted by the indicator lamp 31 can be reflected only in the closed space, so that more light can be irradiated to the indicating light-transmitting member 4, and the brightness of the indicating light-transmitting member 4 is ensured.
Of course, in some specific implementation applications, the size of the circuit board 3 is much larger than that of the indicator 31, and the second side plate 24 and the third side plate 25 abut against the back surface of the circuit board 3, and the light reflecting structure, together with a part of the circuit board 3 and a part of the mounting panel 1, forms a relatively closed space.
Of course, in other embodiments, the first side plate 23 may abut against the back surface of the circuit board 3. The second side panel 24 and/or the third side panel 25 may also abut the indicator light 4.
The second side plate 24 and/or the third side plate 25 are/is abutted against the circuit board 3, so that the circuit board 3 is pressed on the back shell 2 and the mounting panel 1 bracket to also play a role of fixing the circuit board 3; similarly, the second side plate 24 and/or the third side plate 25 abut against the indication translucent member 4, and the indication translucent member 4 can be relatively fixed to the indication window 13.
The space is divided into a first area for arranging the indicator lamp 31 and a second area for arranging the indicator window 13; the size of the first area is larger than the size of the second area in the direction in which the second side panel 24 opposes the third side panel 25. Wherein, the first area corresponds to the first reflecting plane 201, and the second area corresponds to the second reflecting plane 202; indicate printing opacity piece 4 to be located the second region, the size of second region is littleer in relative direction for the light that pilot lamp 31 sent in the first region shines the second region after reflecting, because the size diminishes in relative direction in the second region, makes the second region have the effect of gathering together to light, thereby promotes the luminance of instructing printing opacity piece 4.
Specifically, at least one of the second side panel 24 and the third side panel 25 is a stepped structure such that a distance between the two in the second area portion is smaller than a distance between the two in the third area, for example, the second side panel 24 includes a first sub-panel 242 and a second sub-panel 241 connected and parallel to each other, in which the first sub-panel 242 is closer to the third side panel 25 than the second sub-panel 241, an area between the first sub-panel 242 and the third side panel 25 is the second area, and an area between the second sub-panel 241 and the third side panel 25 is the first area.
Alternatively, at least one of the second side plate 24 and the third side plate 25 includes an inclined plate that is apart from the other side plate in a direction from the indicator light-transmitting member 4 to the indicator lamp 31; for example, the second side plate 24 includes an inclined plate and a straight plate connected to each other, wherein the inclined plate corresponds to the second region and the straight plate corresponds to the first region, and the inclined plate is inclined in a direction away from the third side plate 25 in a direction from the indicator light-transmitting member 4 to the indicator lamp 31, so that the second region becomes gradually larger in an opposite direction in the direction.
Preferably, at least the inner side of the light reflecting structure is a white mirror surface.
