The embodiment of the application provides an intelligent terminal, and this intelligent terminal has spare part less, simple structure, and assembly efficiency is high has. It should be noted that the application of the intelligent terminal is not particularly limited, and the intelligent terminal can be any product or component with display device, such as an intelligent interaction tablet, a television, a notebook computer, a tablet computer, a mobile phone, a virtual reality device, an augmented reality device, a vehicle-mounted display, a sound box, an advertising lamp box, a charging box, and the like.

For easy understanding, the following description will take an intelligent terminal as an example of a television. The display screen of the existing television is generally provided with an optical sensor and an indicator light. The light sensor is used for acquiring an intensity signal of the ambient light and transmitting the acquired intensity signal of the ambient light to the processor so as to realize adjustment of the backlight signal. The indicator lamp responds to different working conditions (such as power-off, power-on standby, normal play and the like) to generate lights with different colors, so that an operator can conveniently acquire the working condition of the television. In the prior art, in order to avoid mutual interference between an ambient light transmission channel and an indicator light transmission channel, the ambient light transmission channel and the indicator light transmission channel are generally separately arranged, so that the technical problems of complex structure or more parts and difficult assembly of a light guide assembly in a television are caused.

In view of the above problems with the existing light guide assembly, embodiments of the present application provide a light guide assembly and a display having the same. Please refer to fig. 1-5, wherein fig. 1-3 only show partial schematic views of the display. The display includes a housing 10, a light sensor 20, an indicator light 30, and a light guide assembly 40.

Referring to fig. 5, fig. 5 is a schematic partial structure of the housing. The housing 10 serves to provide an installation space and protect other components installed therein. The housing 10 may be any shape, such as rectangular, polygonal, circular, oval, etc., and is not limited herein. In particular, the housing 10 is a square rim. A first mounting hole 11 and a second mounting hole 12 are provided at the edge of the housing 10.

Referring to fig. 2 to 4, the light sensor is also referred to as an ambient light sensor 20, and is configured to sense an intensity signal of ambient light, and send the acquired intensity signal to the processor to automatically adjust backlight brightness of the display, so as to reduce power consumption of the product. The construction of the light sensor is not a matter of improvement of the present application, and a person skilled in the art may select a suitable light sensor according to specific needs, which will not be further described herein.

The indicator light 30 may be an LED light for generating different colors of light under different working conditions. The structure and operation of the indicator light 30 are not subject to the improvement of the present application, and a person skilled in the art may select an appropriate indicator light 30 according to specific needs, which will not be further described herein.

It should be noted that the display further includes a circuit board 50, a processor, a backlight module, and the like, which are not improvements of the present application, and are not limited herein. Illustratively, the circuit board 50 may be a PCB circuit board 50. The LED lamp and the light sensor are fixed on a circuit board 50, and the circuit board 50 is fixedly connected with the fixing seat 41.

The light guide assembly 40 includes a fixing base 41, an optical fiber 42 fixed on the fixing base 41, a first light guide 43 and a second light guide 44. The first light guide 43 and the second light guide 44 are integrally formed. The optical fiber 42 includes an optical input end 421 and an optical output end 422, and the second light guide 44 is disposed between the second mounting hole 12 and the optical input end 421, so that the optical input end 421 communicates with the second mounting hole 12 to enable ambient light outside the housing 10 to enter the optical fiber 42 through the optical input end 421. The light emitting end 422 is in communication with the light sensor 20.

In addition, in order to more accurately acquire the signal of the ambient light, a second light guide 44 is disposed between the second mounting hole 12 and the light incident end 421 in this application. Ambient light outside the housing sequentially passes through the second mounting hole 12 and the second light guide 44 and then enters the light inlet 421.

The optical fiber 42 generally includes a core and a cladding layer covering the core. The refractive index of the fiber core and the cladding layer are different, so that the total reflection of the optical signal in the fiber core, namely the transmission of the optical signal, is realized. It can be appreciated that the light-in end 421 of the optical fiber 42 is communicated with the second mounting hole 12, and the ambient light outside the housing 10 can enter the optical fiber 42 from the core of the light-in end 421 through the second mounting hole 12, and the light entering the optical fiber 42 is transmitted in the core along the extending direction of the core, and flows out of the optical fiber 42 from the core of the light-out end 422. Meanwhile, since the light emitting end 422 communicates with the light sensor 20, the light sensor 20 can acquire a signal of ambient light. The structure and dimensions of the optical fiber 42 in the present application are not intended to be modifications, and those skilled in the art may select an appropriate optical fiber 42 according to the needs, and are not limited herein.

The first light guide 43 includes a first light-transmitting surface 431, a second light-transmitting surface 432, and a connection portion 433 connecting the first light-transmitting surface 431 and the second light-transmitting surface 432, the first light-transmitting surface 431 is close to the indicator lamp 30 so that light emitted by the indicator lamp 30 enters the first light guide 43 through the first light-transmitting surface 431, and the second light-transmitting surface 432 is close to the first mounting hole 11 so that light emitted from the second light-transmitting surface 432 is exposed outside the housing 10 through the first mounting hole 11.

Specifically, the first light-transmitting surface 431 is a light-incident surface of the first light-guiding member 43, and the second light-transmitting surface 432 is a light-emitting surface of the first light-guiding member 43. The light generated by the indicator light 30 enters the first light guide member 43 through the first light transmission surface 431, is transmitted to the second light transmission surface 432 in the first light guide member 43, and is emitted through the second light transmission surface 432. The light emitted from the second light-transmitting surface 432 is exposed to the outside of the housing 10 through the first mounting hole 11, so that the operator can observe the light-emitting color of the indicator lamp 30 more conveniently.

Specifically, the second light guide 44 has a substantially square plate-like structure. The end of the second light guide 44 near the housing 10 is substantially flush with the end of the first light guide 43 near the housing 10 (i.e., the end of the first light guide 43 near the second light-transmitting surface 432). The second light guide 44 has a second protruding portion 441 at an end near the housing 10, where the shape of the second protruding portion 441 is adapted to the second mounting hole 12, and the second protruding portion 441 is located in the second mounting hole 12. The end of the second light guide 44 facing away from the housing 10 is provided with a first limiting groove 442, and the cross-sectional shape of the first limiting groove 442 is generally in a "bell mouth" structure, so that the light-entering end 421 of the optical fiber 42 is easily assembled into the first limiting groove 442.

Further, the second light guide 44 may be made of the same material as the first light guide 43, so that the first light guide 43 and the second light guide 44 may be integrally formed, and the first light guide 43 and the second light guide 44 are integrally injection-molded of a transparent PC (polycarbonate) material, for example. In the present application, the first light guide member 43 and the second light guide member 44 may be integrally molded together by injection molding, or the first light guide member 43 may be integrally molded together by injection molding the second light guide member 44 onto the first light guide member 43, which is not limited herein.

The first light guide piece 43 forms the light transmission channel of the indicator light 30, and the second light guide piece 44 and the optical fiber 42 form the light transmission channel of the optical sensor 20, so that mutual interference between the light transmission channel of the indicator light 30 and the light transmission channel of the optical sensor 20 is avoided. Meanwhile, the first light guide piece 43 and the second light guide piece 44 are of an integrated structure, and the optical fiber 42 and the first light guide piece 43 are fixed on the same fixed seat 41, so that parts of the light guide assembly 40 are fewer, the structure is simpler and more compact, and the assembly efficiency of the light guide assembly 40 is improved. In addition, the optical sensor in the present application is communicated with the external environment through the optical fiber 42 and the second light guide 44, so that the proportion of the ambient light received by the optical sensor 20 can be increased, which is beneficial to the volume of the smaller light guide assembly.

Specifically, the fixing base 41 includes a mounting plate 411, and the mounting plate 411 is generally in a rectangular parallelepiped structure and is horizontally disposed. The mounting plate 411 is provided with a light guide hole 412 near the right end, and the light guide hole 412 is arranged corresponding to the first light guide column. The light emitted by the indicator light 30 enters the first light guide member 43 through the light guide hole 412 and the first light transmission surface 431. For example, the first light guide 43 (i.e., the connection portion 433) has a substantially square plate-like structure, and the first light-transmitting surface 431 and the second light-transmitting surface 432 are respectively two end surfaces of the first light guide 43 in the longitudinal direction. The part of the wall surface of the first light guide member 43 near one end of the first light transmission surface 431 is fixedly connected with the mounting plate 411, and the first light transmission surface 431 extends into the light guide hole 412 and is arranged opposite to the indicator lamp 30. The second light-transmitting surface 432 is provided with a first protruding portion 435 on a surface facing away from the mounting plate 411. The shape of the first protruding part 435 is matched with that of the first mounting hole 11, and the first protruding part 435 is positioned in the first mounting hole 11. The second light-transmitting surface 432 may be a top surface of the first protruding portion 435 (a surface of the first protruding portion facing the first mounting hole), or may be a top surface of the first protruding portion 435 and a side surface connected to the top surface. In this embodiment, the first light guide 43 has a simple structure, and the light emitted by the indicator light 30 is transmitted through the first light guide 43 in a straight line, which is beneficial to reducing the transmission time of the first light guide 43, thereby improving the response speed.

In order to avoid interference of the light of the indicator light 30, in some embodiments of the present application, a light shielding layer 434 is disposed on a side surface of the connection portion 433. The light shielding layer 434 may be disposed on a portion of the side surface of the connection portion 433, and illustratively, the light shielding layer 434 is disposed at a side of the connection portion 433 facing away from the light emitting direction of the indicator lamp 30. Of course, the light shielding layer 434 may be disposed on all sides of the connection portion 433 in this application (i.e., all sides of the connection portion 433 except the first light transmitting surface 431 and the second light transmitting surface 432). The light shielding layer 434 may be a paint layer or a black plastic layer.

Illustratively, the light shielding layer 434 and the fixing base 41 are formed of the same light shielding material (e.g., black ABS plastic, black acrylonitrile/butadiene/styrene copolymer), and the first light guide 43 and the second light guide 44 are integrally formed of a light guiding plastic, such as a transparent polycarbonate material (transparent PC material). The mounting plate 411 (i.e. the fixing seat 41), the light shielding layer 434 and the first light guide member 43 are integrally formed by co-injection, for example, the fixing seat 41 is integrally injection molded, and then the first light guide member 43 and the second light guide member 44 are injection molded on the hardened fixing seat 41. Of course, the fixing base 41 and the light guide members (the first light guide member and the second light guide member) may be injection molded at the same time. For example, the light shielding layer 434 and the mounting plate 411 may be integrally injection molded, and the first light guide 43 and the second light guide 44 may be integrally molded and then fixed to the mounting plate 411 by adhesion. And are not limited herein. The embodiment is beneficial to improving the structural strength of the light guide component, improving the production and assembly efficiency, reducing the number of dies and reducing the preparation cost.

In some embodiments of the present application, the fixing seat 41 is provided with a second limiting groove 413, and the second limiting groove 413 is adapted to the light emitting end 422. Specifically, a first avoiding port 4111 is disposed at a position of the mounting plate 411 corresponding to the light emitting end 422, and the second limiting groove 413 is disposed at a side of the first avoiding port 4111 facing away from the first light guide 43. The second limiting groove 413 is substantially sleeve-shaped, a third mounting opening 4131 is formed in a wall surface of the second limiting groove 413, and the third mounting opening 4131 extends along a length direction of the second limiting groove 413 and penetrates through two ends of the second limiting groove 413. The light emitting end 422 is installed into the second limiting groove 413 through the third installation opening 4131. It can be appreciated that, in this embodiment, the second limiting groove 413 and the third mounting hole 4131 are formed on the fixing base 41, so that the light emitting end 422 can be conveniently fixed on the fixing base 41, which is beneficial to improving the assembly efficiency and stability of the optical fiber 42.

In other embodiments of the present application, the light guide assembly 40 further includes a light shielding column 414, and the optical fiber 42 is disposed between the light shielding column 414 and the first light guide 43; the light shielding posts 414, the optical fibers 42, and the first light guide members 43 are disposed at intervals along the length direction of the fixing base 41. Specifically, the light shielding posts 414, the optical fibers 42, and the first light guide members 43 are disposed at intervals along the length direction of the mounting plate 411, and the light emitting ends 422 of the optical fibers 42 are disposed on one side of the long side of the mounting plate 411 and near the middle. The light shielding column 414 and the first light guide 43 are located on the same side as the optical fiber 42. The light shielding column 414 and the first light guide 43 are respectively located at the left and right sides of the optical fiber 42 and are disposed near the optical fiber 42. One end of the light shielding column 414 is fixedly connected with the fixing seat 41, and one end of the light shielding column 414, which is away from the fixing seat 41, is connected with one end of the second light guide 44, which is away from the first light guide 43. In this application, the light transmission channels and the light sensor 20 are independent light guide channels, so that the distance between the light shielding column 414, the first light guide member 43 and the optical fiber 42 is relatively short, which is beneficial to improving the structural compactness and the connection strength of the light guide assembly 40. In addition, since the second light guide 44 can be connected to the light shielding column 414, the housing 10 and the first light guide 43, the light incident end 421 of the light beam is clamped to the second limiting groove 413 on the second light guide 44, and the light emitting end 422 of the optical fiber 42 is clamped to the first limiting groove 442 on the mounting plate 411, so that the connection strength and the structural compactness of the light guide assembly 40 are further improved.

In some embodiments of the present application, the fixing base 41 further includes a light shielding plate 415 disposed around the light guiding hole 412, and the light shielding plate 415 and the first light guiding member 43 are disposed on two opposite sides of the mounting plate 411. The light shielding plate 415 encloses a receiving cavity 4151 for mounting the indicator lamp 30, and the first light-transmitting surface 431 is in communication with the receiving cavity 4151. Specifically, the structure of the light shielding plate 415 is substantially square, and an end of the light shielding plate 415 facing away from the mounting plate 411 is open.

This structure is through setting up light screen 415 around the LED lamp to can prevent the LED lamp light leak. Meanwhile, a certain gap exists between the mounting plate 411 and the circuit board 50, so that extrusion collision between the electrical components protruding from the circuit board 50 and the mounting plate 411 when the circuit board 50 is mounted on the mounting plate 411 is avoided, and the production efficiency of products is improved.

In some embodiments of the present application, a positioning post 416 is disposed on a side of the mounting plate 411 facing away from the first light guide 43, and illustratively, the positioning post 416 is disposed at a right end of the mounting plate 411.

The end of the circular boss 417 away from the mounting plate 411 and the end of the coaming away from the mounting plate 411 are generally located on the same horizontal plane, so that the end of the coaming and the circular boss 417 away from the mounting plate 411 are respectively abutted with the two ends of the circuit board 50, which is beneficial to the contact area and the mounting stability between the circuit board 50 and the mounting plate 411. The circular boss 417 is provided therein with a first screw hole 4171, and the first screw hole 4171 extends in the axial direction of the circular boss 417. The circuit board 50 is provided with a second threaded hole 52, and a screw passes through the first threaded hole 4171 and the second threaded hole 52 simultaneously to fixedly connect the circuit board 50 with the mounting plate 411.
