Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of testing electronic devices, and in particular to a functional module and a terminal device. BACKGROUND

[0002] In the development of current smart phone products, as consumers increasingly demand more integrated functionality and appearance design, how to ensure comprehensive functionality while achieving a more streamlined and integrated appearance design has become an important challenge for phone manufacturers. In particular, in the design of ring flash, breathing light, rear light sensor, and laser, traditional methods often separate these functional modules and place them independently on the appearance structure of the phone.

[0046] The following will be described in combination with Figures 1 to 4 The present embodiment describes the function module and the terminal device provided by the present embodiment, which includes but is not limited to mobile phone, vehicle-mounted terminal, tablet computer, notebook computer, palm computer, wearable device and pedometer. The specific type of terminal device is not limited in the embodiments of the present application.

[0047] The present embodiment provides a function module, such as Figures 1 to 3As shown, the functional module includes: a circuit board 10, a lens assembly 20, a first printed circuit board 30, a second printed circuit board 40 and a separator 50. The circuit board 10 is used for electrical connection with the mainboard; the lens assembly 20 has a light-transmitting region; the first printed circuit board 30 is arranged at a position corresponding to the light-transmitting region of the circuit board 10 or a position larger than the position corresponding to the light-transmitting region and is electrically connected with the circuit board 10, and at least one illuminating device 60 is integrated on the first printed circuit board 30; the second printed circuit board 40 is arranged at a position not including the at least one illuminating device 60 on the first printed circuit board 30 and is electrically connected with the first printed circuit board 30, and at least one light-sensing device 70 is integrated on the second printed circuit board 40; and the separator 50 is arranged between the at least one light-sensing device 70 and the at least one illuminating device 60 to isolate the light generated by the at least one illuminating device 60 from propagating to the at least one light-sensing device 70.

[0048] Specifically, the circuit board 10 can be a flexible circuit board, and the circuit board 10 (Flexible Printed Circuit, FPC) serves as a bridge connecting the mainboard and other components. The lens assembly 20 contains a light-transmitting region for allowing light to pass through to support the illumination and light-sensing functions in the module. The first printed circuit board 30 is arranged at a position corresponding to the light-transmitting region of the lens assembly 20 or a position larger than the position corresponding to the light-transmitting region. The circuit board 10 is connected to the lens assembly 20 through a circuit board back adhesive 100. The first printed circuit board 30 is electrically connected with the circuit board 10 and integrates at least one illuminating device 60 (such as a flash 620 and an RGB light 610). The second printed circuit board 40 is arranged at a region not integrating the illuminating device 60 on the first printed circuit board 30 and is electrically connected with the first printed circuit board 30, and the second printed circuit board 40 integrates at least one light-sensing device 70 (such as a TOF sensor and a rear light-sensing device 70). The separator 50 is arranged between the illuminating device 60 and the light-sensing device 70 to effectively isolate the light generated by the illuminating device 60 and prevent it from interfering with the normal operation of the light-sensing device 70.

[0049] When the mainboard sends an illumination instruction to the functional module, the circuit board 10 transmits the signal to the first printed circuit board 30. Upon receiving the signal, the illuminating device 60 on the first printed circuit board 30 immediately lights up and emits light. The light passes through the light-transmitting region of the lens assembly 20 and illuminates the target region. At the same time or after the illuminating device 60 lights up, the light-sensing device 70 on the second printed circuit board 40 continues to work. The light-sensing device 70 receives light from the surrounding environment (including the light emitted by the illuminating device 60, but due to the presence of the separator 50, this part of light is effectively isolated and does not directly interfere with the light-sensing device 70). The light-sensing device 70 converts the received light into an electrical signal and transmits it to the mainboard for further processing.

[0050] The functional module provided by the embodiment of the present application integrates the first printed circuit board 30 and the second printed circuit board 40 in one functional module, which are respectively used for placing the lighting device 60 and the light sensing device 70, and realizes high integration of multiple functions. The number of parts is reduced, and the device as a whole is more compact and thin. The design of high integration not only reduces the manufacturing cost, but also reduces the design cost and the assembly cost. Since all the related functions are integrated in one functional module, the production process can be simplified, the production efficiency is improved, and thus the production cost is reduced. At the same time, the additional assembly and debugging work caused by scattered design is also reduced. Since all the functions are integrated in one module, the appearance can be more flexibly designed, and a more simple and integrated visual effect is realized. In addition, the present application sets the isolation piece 50 between the lighting device 60 and the light sensing device 70, which can effectively prevent the light generated by the lighting device 60 from interfering with the normal work of the light sensing device 70.

[0051] In some embodiments, as shown in Figs. 2 and 3, the lens assembly 20 includes a decorative piece 210 and a lens 220. The decorative piece 210 is bonded with the back plate 90 into one whole body by means of glue dispensing. The decorative piece 210 not only plays a beautifying role, but also forms a mounting space 230 for accommodating the lens 220 and other electronic components. The lens 220 is connected in the decorative piece 210 through lens back glue 240. Both ends of the mounting space 230 are provided with openings, which facilitates the installation and connection of the assembly. The lens 220 is arranged at the opening at one end of the mounting space 230, which is used for protecting the internal electronic components and allowing light to pass through to support the lighting and light sensing functions. The circuit board 10 is arranged at the opening at the other end of the mounting space 230, so that the circuit board 10 can be electrically connected with other electronic components (such as the lighting device 60, the light sensing device 70, the first printed circuit board 30 and the second printed circuit board 40) in the mounting space 230. Figure 1 Figure 2 In some embodiments, as shown in Figs. 2 and 3, the lens assembly 20 includes a decorative piece 210 and a lens 220. The decorative piece 210 is bonded with the back plate 90 into one whole body by means of glue dispensing. The decorative piece 210 not only plays a beautifying role, but also forms a mounting space 230 for accommodating the lens 220 and other electronic components. The lens 220 is connected in the decorative piece 210 through lens back glue 240. Both ends of the mounting space 230 are provided with openings, which facilitates the installation and connection of the assembly. The lens 220 is arranged at the opening at one end of the mounting space 230, which is used for protecting the internal electronic components and allowing light to pass through to support the lighting and light sensing functions. The circuit board 10 is arranged at the opening at the other end of the mounting space 230, so that the circuit board 10 can be electrically connected with other electronic components (such as the lighting device 60, the light sensing device 70, the first printed circuit board 30 and the second printed circuit board 40) in the mounting space 230.

[0052] In the embodiment, the lighting device 60 and the light sensing device 70 are integrated on the first printed circuit board 30 and the second printed circuit board 40 respectively, and are arranged in the mounting space 230. They communicate with the main board through the circuit board 10, receive instructions and perform corresponding functions.

[0053] When the device is started, the main board sends an initialization instruction to the functional module through the circuit board 10. After receiving the instruction, the functional module starts self-detection to ensure that all components are in normal working state.

[0054] When lighting is needed, the main board sends a lighting instruction to the functional module. After receiving the instruction, the lighting device 60 on the first printed circuit board 30 is lit and emits light. The light is projected to the external environment through the lens 220, realizing the lighting effect. ​

[0055] During or after the lighting function is activated, the light sensor 70 on the second printed circuit board 40 continuously monitors changes in ambient light. The light sensor 70 converts the received light information into electrical signals, which are then transmitted to the main board via the circuit board 10 for further processing.

[0056] After receiving the electrical signal transmitted by the photosensor 70, the motherboard processes and analyzes the data. Based on the processing results, the motherboard may send new instructions to the functional modules to adjust the brightness or color of the lighting device 60 or turn off the lighting function. Simultaneously, the motherboard may also feed back the processing results to other system components to achieve more complex device functions.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, the installation space 230 is arranged in a stepped manner, including at least two sub-spaces arranged in a stacked manner from top to bottom. The lens 220 is located in the uppermost sub-space, and the lighting device 60, the light sensor 70, the first printed circuit board 30, and the second printed circuit board 40 are located in the other sub-spaces.

[0058] Specifically, the installation space 230 has four sub-spaces stacked sequentially from top to bottom: the first sub-space, the second sub-space, the third sub-space, and the fourth sub-space. The first, second, and third sub-spaces are arranged in a stepped layout, while the fourth sub-space is positioned opposite them. The stepped layout of the first, second, and third sub-spaces allows for the rational distribution of different components according to their functional requirements, reducing mutual interference and improving the compactness and reliability of the equipment. The relative positioning of the fourth sub-space with the aforementioned three sub-spaces allows for a larger size, facilitating the simultaneous installation of multiple flashlights and multiple RGB lights to provide better illumination and various lighting effects.

[0059] In one example, the first subspace is located at the top and is specifically designed to house the lens 220. The lens 220 serves as a window for light projection. By placing it in the topmost subspace, it is ensured that light can be smoothly projected into the external environment while protecting the internal electronic components from external interference.

[0060] In one example, the second subspace is located below the first subspace and is used to install the photosensor 70 and the isolator 50. The photosensor 70 may include active and passive photosensors, such as active proximity sensors and passive light intensity sensors, which are responsible for monitoring changes in ambient light and providing necessary environmental information to the device. The isolator 50 is used to isolate the photosensor 70 from other subspaces to avoid light interference from other subspaces.

[0061] In one example, the third subspace is located below the second subspace and is used to mount the second printed circuit board 40 and the lighting device 60. The second printed circuit board 40 is used for the circuit connection and control logic of the light sensor 70 and is a component of the circuit in the functional module. The lighting device 60 is responsible for emitting light to realize the lighting function.

[0062] The fourth subspace, located at the bottom layer, is used to mount the first printed circuit board 30. The first printed circuit board 30 carries the circuit connections and control logic of the lighting device 60, as well as the second printed circuit board 40, and is a component of the circuitry within the functional module. In some embodiments, such as... Figures 1 to 4 As shown, the light sensor 70 includes a distance light sensor 710 and an intensity light sensor 720; the isolation member 50 includes a light-shielding sleeve disposed in one of the subspaces (the second subspace), covering the distance light sensor 710 and the intensity light sensor 720. The light-shielding sleeve has an emission hole 510 for transmitting signals and a receiving hole 520 for receiving signals corresponding to the distance light sensor 710, as well as a light-sensing hole 530 for detecting light intensity corresponding to the intensity light sensor 720.

[0063] In this embodiment, the distance light sensor 710 is used to detect the distance between an object and the functional module. Distance measurement is typically achieved by emitting and receiving signals (such as infrared light, laser light, etc.). The intensity light sensor 720 is used to detect the ambient light intensity. The brightness, color, and other parameters of the device can be adjusted based on the received light intensity to adapt to different ambient lighting conditions.

[0064] To ensure the accurate and reliable operation of the distance light sensor 710 and the intensity light sensor 720, an isolation element 50 is needed to prevent interference between them and from the external environment. A light-shielding sleeve, as one type of isolation element 50, effectively achieves this goal. The light-shielding sleeve is disposed in the second subspace, covering the distance light sensor 710 and the intensity light sensor 720. Its main function is to block external light and signals, preventing them from causing unnecessary interference to the light sensor 70. The light-shielding sleeve has a transmitting hole 510 for transmitting signals and a receiving hole 520 for receiving signals corresponding to the distance light sensor 710. These two holes allow the distance light sensor 710 to transmit and receive signals without interference from the external environment. In this way, the distance light sensor 710 can accurately measure the distance between the object and the functional module. The light-shielding sleeve also has a light-sensing hole 530 corresponding to the intensity light sensor 720 for detecting light intensity. The light-sensing hole 530 allows the intensity light sensor 720 to receive external light and adjust the device parameters according to the light intensity. This ensures that the intensity light sensor 720 can accurately detect the light intensity without being affected by the light shield itself or other components.

[0065] Specifically, the light shielding sleeve is provided with a first mounting groove 540 for mounting the distance light sensing device 710 and a second mounting groove 550 for mounting the intensity light sensing device 720. The first mounting groove 540 is provided with an emitting hole 510 and a receiving hole 520, and the second mounting groove 550 is provided with a light sensing hole 530. The first mounting groove 540 is sized and shaped to match the distance light sensing device 710, ensuring that it can be stably mounted in the light shielding sleeve. At a proper position of the first mounting groove 540, the emitting hole 510 and the receiving hole 520 are provided. The two holes correspond to the emitting end and the receiving end of the distance light sensing device 710 respectively, allowing the emission and reception of signals (such as infrared rays, laser, etc.). The second mounting groove 550 is sized and shaped to match the intensity light sensing device 720, ensuring that it can be stably mounted in the light shielding sleeve. At a proper position of the second mounting groove 550, the light sensing hole 530 is provided. The hole corresponds to the light sensing surface of the intensity light sensing device 720, allowing external light to enter and be received by the intensity light sensing device 720.

[0066] In some embodiments, as shown in Figure 1 and Figure 2 The lighting device 60 includes a flash 620 and an RGB lamp 610. The flash 620 is arranged at a peripheral region of a surface of the first printed circuit board 30 and is electrically connected with the first printed circuit board 30; the RGB lamp 610 is arranged at a middle region of the surface of the first printed circuit board 30 and is electrically connected with the first printed circuit board 30; the second printed circuit board 40 is arranged at an inner region of the surface of the first printed circuit board 30, and the middle region of the surface of the first printed circuit board 30 is located between the peripheral region and the inner region.

[0067] The flash 620 is a kind of lighting device 60 capable of providing intense and short light. When taking pictures or recording videos, the flash 620 can be used for light compensation to ensure that the shooting object is clear and bright. The RGB lamp 610 is a kind of lighting device 60 capable of emitting light of multiple colors. By adjusting the proportion of light of red, green and blue colors in the RGB lamp 610, various different color effects can be produced. The first printed circuit board 30 is a main body carrying the flash 620 and the RGB lamp 610, and the surface is divided into a peripheral region, a middle region and an inner region. The flash 620 is arranged at the peripheral region, the RGB lamp 610 is arranged at the middle region, and the second printed circuit board 40 is arranged at the inner region. By arranging the flash 620 and the RGB lamp 610 at different regions of the first printed circuit board 30 respectively and introducing the second printed circuit board 40, the modularized setting of the lighting device 60 is realized.

[0068] In some embodiments, as shown in Figure 1 and Figure 2As shown, the flashlights 620 and / or the RGB lights 610 are provided in multiple numbers. The multiple flashlights 620 are arranged in a ring shape in the peripheral region of the first printed circuit board 30, and the multiple RGB lights 610 are arranged in a ring shape in the middle region of the first printed circuit board 30.

[0069] In this embodiment, the multiple flashlights 620 are arranged in a ring shape in the peripheral region of the first printed circuit board 30, which can ensure that the light of the flashlights 620 can uniformly cover the peripheral region of the device, providing sufficient light supplement for photographing or video recording. At the same time, the ring-shaped layout can also make the light of the flashlights 620 more soft and uniform, avoiding the generation of dazzling light.

[0070] Similarly to the flashlights 620, the multiple RGB lights 610 are also arranged in a ring shape in the middle region of the first printed circuit board 30, which can make the light emitted by the RGB lights 610 more uniform and beautiful, and also facilitate the user to observe and adjust the color effect. By adjusting the proportion of the light of the three colors of red, green and blue in the RGB lights 610, various different color effects can be generated, adding more colors and atmosphere to the device.

[0071] The adoption of multiple flashlights 620 and RGB lights 610 in a ring shape in this embodiment can significantly improve the coverage range and effect of the lighting device 60, which is not only suitable for the light supplement demand during photographing or video recording, but also can be used to create a specific atmosphere and visual effect.

[0072] In one example, as shown in Figure 1 and Figure 2 The lighting device 60 further includes a light uniformizing sheet 630 and a ring-shaped flashlight cover 640. The light uniformizing sheet 630 corresponds to at least a part of the flashlights 620 and the RGB lights 610, and the ring-shaped flashlight cover 640 is arranged on the light uniformizing sheet 630.

[0073] The main function of the light uniformizing sheet 630 is to homogenize the light. The light uniformizing sheet 630 corresponds to at least a part of the flashlights 620 and the RGB lights 610. The light emitted by the flashlights 620 and the RGB lights 610 will become more uniform and soft after passing through the light uniformizing sheet 630, avoiding the problem of too concentrated or dispersed light. The light uniformizing sheet 630 can be adjusted according to the specific layout and power of the flashlights 620 and the RGB lights 610 to ensure the best lighting effect. The shape of the ring-shaped flashlight cover 640 is usually ring-shaped or ring-like. The ring-shaped flashlight cover 640 is arranged on the light uniformizing sheet 630 and corresponds to the flashlights 620. The main function of the ring-shaped flashlight cover 640 is to further diffuse and homogenize the light of the flashlights 620, and also can prevent the light from directly irradiating the eyes or other sensitive parts of the user, improving the safety of use. In addition, the ring-shaped flashlight cover 640 can also play a role in protecting the flashlights 620 and the light uniformizing sheet 630 from damage or pollution from the outside.
