Description

Technical Field

[0001] This utility model relates to the field of OLED screen dimming technology, and in particular to a low-power intelligent dimming device for OLED screens. Background Technology

[0002] OLED display modules are typically in the form of circuit boards, which are electrically connected and secured by plugging into corresponding slots on the device's motherboard using pins on the board's edge. However, this traditional plug-in mounting method has revealed some inherent technical flaws in practical applications.

[0003] First, in harsh working environments such as those involving vibration, shock, or temperature cycling, slight loosening or displacement can easily occur between the circuit board and its slot due to mechanical stress, leading to poor electrical contact. This unstable contact can cause problems such as display flickering, signal interruption, or even equipment shutdown, seriously affecting the reliability and lifespan of the equipment and increasing maintenance costs.

[0004] Secondly, traditional circuit board structures typically lack effective anti-misinsertion (foolproof) designs. During installation, if an operator mistakenly inserts the board in the wrong direction, it can easily cause misalignment of the electrical contacts between the pins and the slot, potentially leading to short circuits, signal conflicts, and burning out related circuits on the board or motherboard, resulting in irreversible equipment damage and posing a significant safety hazard.

[0005] Therefore, there is an urgent need in this field for a new type of low-power intelligent dimming device for OLED screens to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to propose a low-power intelligent dimming device for OLED screens to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, one embodiment of the present invention provides a low-power intelligent dimming device for an OLED screen, comprising a board, an OLED screen, and pins, wherein the OLED screen is fixedly connected to the top of the board, and a plurality of pins are fixedly connected to one edge of the board. The top and bottom of the plate are fixedly connected with protrusions, the protrusions correspond to the pins, and the protrusion ends on the bottom surface of the plate are provided with anti-fooling notches; The plate has openings at both edges, and a sleeve is fixedly connected inside the opening. A buckle is detachably connected to the bottom of the sleeve, and an elastic foot is fixedly connected to the bottom end of the buckle. The buckle is bent at ninety degrees. A connector is inserted into the top of the sleeve, and the connector is threadedly connected to the top of the buckle.

[0009] Preferably, in any of the above embodiments, the substrate of the plate is polyimide, and the thickness of the protrusion on the top surface of the plate is less than the thickness of the protrusion on the bottom surface of the plate.

[0010] The above technical solution is adopted: This low-power intelligent dimming device for OLED screens mainly consists of a board, an OLED screen, and pins. Its dimming principle is based on a built-in dimming module, which can intelligently adjust the brightness of the OLED screen according to the ambient light intensity and preset parameters to achieve a low-power and comfortable display effect.

[0011] In terms of installation, when the board is fully inserted into the corresponding slot in the chassis, the elastic feet at the bottom of the sleeve located at the edge opening of the board will spring into the pre-set slots or grooves on the chassis crossbeam. The elastic feet use their own elasticity to press the board firmly against the motherboard slot, creating a positive locking force, fundamentally solving the problem of poor contact of plug-in boards in vibrating environments. Simultaneously, a raised structure is provided at the top and bottom of the board at the edge where the pins are located, and a foolproof notch is provided at the end of the raised structure on the bottom surface of the board. This foolproof notch matches the corresponding structure of the chassis slot, ensuring that the board is not inserted incorrectly, avoiding equipment damage or malfunction due to incorrect insertion.

[0012] The connector (hex socket screw) is used to thread the clip and the sleeve, which serves to fix and adjust the position of the clip. The elasticity of the spring foot and the degree of fit with the chassis clip can be finely adjusted according to the actual installation situation.

[0013] Preferably, in any of the above embodiments, the pins are arranged in two rows side by side, and the inner wall of the opening is threadedly connected to the sleeve.

[0014] Preferably, as described in any of the above embodiments, the top surface of the sleeve is flush with the top surface of the plate, and the bottom surface of the sleeve is flush with the bottom surface of the plate. The core design of this dimming device is: by using an elastic foot that springs into the crossbeam slot or groove of the chassis, the plate is pressed tightly against the motherboard slot using its own elasticity, forming a positive locking force. This design fundamentally solves the problem of poor contact of plug-in boards in vibrating environments, greatly improving the stability and reliability of the device in various complex environments, and reducing equipment failures and maintenance costs caused by poor contact.

[0015] Raised structures are provided at the top and bottom of the board body along the edge where the pins are located to reinforce the structure at the pins, and a foolproof notch is provided at the raised end of the bottom surface of the board body. This foolproof design ensures that the board body will not be inserted backwards during installation, avoiding serious consequences such as short circuits and equipment damage that may be caused by incorrect insertion, improving the accuracy and efficiency of installation, and reducing the difficulty and risk of operation.

[0016] Preferably, the buckle and the elastic foot are made of plastic, and a dimming module is fixedly connected to the bottom of the plate.

[0017] Preferably, in any of the above solutions, the connector is a hexagonal socket screw, and the connector is made of plastic.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This low-power intelligent dimming device for OLED screens utilizes a design where elastic feet spring into the chassis beam's slots or grooves, using their own elasticity to firmly press the board against the motherboard slot, creating a strong locking force. This design fundamentally solves the problem of poor contact in vibrating environments with plug-in boards, greatly improving the device's operational stability and reliability in various complex environments, and reducing equipment failures and maintenance costs caused by poor contact.

[0019] Raised structures are provided at the top and bottom of the board body along the edge where the pins are located to reinforce the structure at the pins, and a foolproof notch is provided at the raised end of the bottom surface of the board body. This foolproof design ensures that the board body will not be inserted backwards during installation, avoiding serious consequences such as short circuits and equipment damage that may be caused by incorrect insertion, improving the accuracy and efficiency of installation, and reducing the difficulty and risk of operation.

[0025] like Figure 1-4 As shown, this low-power intelligent dimming device for OLED screen includes a board 1, an OLED screen 2, and pins 3. The OLED screen 2 is fixedly connected to the top of the board 1, and several pins 3 are fixedly connected to one edge of the board 1. The top and bottom of the plate 1 are fixedly connected with protrusions 4, which correspond to the pins 3. The protrusions 4 on the bottom surface of the plate 1 are provided with anti-fooling notches 5. The plate 1 has openings 6 at both edges. A sleeve 7 is fixedly connected inside the opening 6. A buckle 8 is detachably connected to the bottom of the sleeve 7. An elastic foot 9 is fixedly connected to the bottom of the buckle 8. The buckle 8 is bent at ninety degrees. A connector 10 is inserted into the top of the sleeve 7, and the connector 10 is threadedly connected to the top of the buckle 8.

[0026] Example 1: The substrate of the board 1 is polyimide, and the thickness of the protrusion 4 on the top surface of the board 1 is less than the thickness of the protrusion 4 on the bottom surface of the board 1. Two rows of pins 3 are arranged side-by-side, and the inner wall of the opening 6 is threadedly connected to the sleeve 7. The top surface of the sleeve 7 is flush with the top surface of the board 1, and the bottom surface of the sleeve 7 is flush with the bottom surface of the board 1. The clips 8 and elastic feet 9 are made of plastic, and a dimming module is fixedly connected to the bottom of the board 1. The connector 10 is specifically a hexagonal socket head cap screw, and the connector 10 is made of plastic.

[0027] Example 2: This low-power intelligent dimming device for OLED screens mainly consists of a board 1, an OLED screen 2, and pins 3. Its dimming principle is based on a built-in dimming module, which intelligently adjusts the brightness of the OLED screen 2 according to the ambient light intensity and preset parameters to achieve a low-power and comfortable display effect.

[0028] In terms of installation, when the board 1 is fully inserted into the corresponding slot in the chassis, the elastic foot 9 at the bottom of the sleeve 7 located at the opening 6 on the edge of the board 1 will spring into the pre-set slot or groove on the chassis crossbeam. The elastic foot 9 uses its own elasticity to press the board 1 tightly against the motherboard slot, forming a positive locking force, which fundamentally solves the problem of poor contact of plug-in boards in vibrating environments. At the same time, a protrusion 4 is provided at the top and bottom of the board 1 at the edge where the pin 3 is located, and a foolproof notch 5 is provided at the end of the protrusion 4 on the bottom surface of the board 1. Through the matching of the foolproof notch 5 with the corresponding structure of the chassis slot, it is ensured that the board 1 will not be inserted backwards, avoiding equipment damage or malfunction due to reverse insertion.

[0029] The connector 10 (hex socket screw) is used to thread the clip 8 and the sleeve 7, which serves to fix and adjust the position of the clip 8. The elastic force of the elastic foot 9 and the degree of fit with the chassis clip can be finely adjusted according to the actual installation situation.

[0030] The working principle of this utility model is as follows: The substrate 1 is made of polyimide, a material with good insulation, heat resistance, and mechanical properties. An OLED screen 2 is prepared, ensuring its display performance meets design requirements. The pins 3 are made of a highly conductive metal and machined into two parallel rows. Protrusions 4 are fixed to the top and bottom of the substrate 1 using injection molding, with the thickness of the protrusions 4 on the top surface of the substrate 1 being less than the thickness of the protrusions 4 on the bottom surface. A foolproof notch 5 is provided at the end of the protrusions 4 on the bottom surface of the substrate 1. Openings 6 are provided at both edges of the substrate 1. A sleeve 7 is fixed inside the opening 6 via a threaded connection, ensuring that the top and bottom surfaces of the sleeve 7 are flush with the top and bottom surfaces of the substrate 1. The clips 8 and elastic feet 9 are made of plastic. The clips 8 are machined into a 90-degree bend and fixedly connected to the elastic feet 9. The clips 8 are then detachably connected to the bottom of the sleeve 7. The connector 10 is a plastic hexagonal screw. Meanwhile, a dimming module is installed at the bottom of panel 1.

[0031] First, securely attach the OLED screen 2 to the top of the board 1. Next, securely attach the pin 3 to one edge of the board 1. Then, screw the sleeve 7 into the opening 6 on the edge of the board 1, ensuring a secure installation. Afterward, install the clip 8 at the bottom of the sleeve 7 and initially secure it with the connector 10 (hex socket screw). At this point, the position of the clip 8 can be finely adjusted as needed.

[0032] Insert the assembled device into the corresponding slot in the chassis. During insertion, ensure that the anti-fooling notch 5 on the bottom of board 1 aligns with the corresponding structure of the chassis slot to ensure correct insertion. When board 1 is fully in place, the spring-loaded foot 9 springs into the pre-set slot or groove on the chassis crossbeam, using its own elasticity to firmly press board 1 into the motherboard slot. At this point, the device and motherboard are stably connected, and the dimming module begins to work, automatically adjusting the brightness of the OLED screen 2 according to the ambient light intensity. For example, in a bright environment, the dimming module will reduce the brightness of the OLED screen 2 to save power; in a dim environment, the dimming module will appropriately increase the brightness of the OLED screen 2 to ensure display clarity.

[0033] Compared with the prior art, the present invention has the following advantages: This low-power intelligent dimming device for OLED screens utilizes a design where elastic feet 9 spring into the chassis beam slots or grooves, using their own elasticity to firmly press board 1 against the motherboard slot, creating a strong locking force. This design fundamentally solves the problem of poor contact in vibrating environments for plug-in boards, greatly improving the device's stability and reliability in various complex environments, and reducing equipment failures and maintenance costs caused by poor contact.

[0034] A protrusion 4 is provided at the top and bottom of the board 1 at the edge where the pin 3 is located to reinforce the structure at the pin 3, and a foolproof notch 5 is provided at the end of the protrusion 4 on the bottom surface of the board 1. This foolproof design ensures that the board 1 will not be inserted backwards during installation, avoiding serious consequences such as short circuits and equipment damage that may be caused by reverse insertion, improving the accuracy and efficiency of installation, and reducing the difficulty and risk of operation.
