Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically a display screen module with an active infrared sensing device. Background Technology

[0002] A display screen is an output device of an electronic device used to convert electronic signals into visible images, text, or video; it is a core component of human-computer interaction. An infrared sensor is an electronic component that achieves non-contact sensing by detecting infrared radiation. It is divided into active and passive types and is widely used in industrial and consumer electronics fields.

[0003] Existing infrared sensing devices and display modules typically adopt a separate design, requiring the infrared sensor to be installed separately on an external structure. This results in increased overall size, low space utilization, complex assembly, and higher costs. Furthermore, traditional devices often rely on screws to fix the back cover, which provides a certain structural strength but makes quick disassembly and assembly difficult. If the device is assembled using a snap-fit ​​method, the back cover may detach directly in the event of an accidental drop or impact, increasing the risk of damage to internal components. Therefore, we propose a display module with an active infrared sensing device. Utility Model Content

By directly integrating the infrared sensor onto a flexible circuit board, it eliminates the need for independent brackets and wiring space, reducing assembly difficulty and production costs. The engagement of the snap-fit ​​pins and snap-fit ​​slots enables quick assembly and disassembly of the outer shell and back cover. The linkage structure of the reinforcement components ensures a high-strength connection, effectively resisting drop impacts and solving the background problem.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 This utility model provides a technical solution: a display module with an active infrared sensing device, including a housing 1, a rear cover 6 on the rear side of the housing 1, a plurality of snap-fit ​​feet 8 fixedly connected to the front side of the rear cover 6, a plurality of snap-fit ​​grooves 9 fixedly connected to the inner side wall of the housing 1, the snap-fit ​​feet 8 snapping into the snap-fit ​​grooves 9, a mounting groove 13 on the front side of the housing 1, a display screen 2 mounted on the mounting groove 13, a charging interface 16 on the bottom of the housing 1, a flexible circuit board 10 fixedly mounted inside the housing 1 on the rear side of the display screen 2, an infrared sensor 14 mounted on the bottom of the flexible circuit board 10, an infrared emitting hole 3 mounted on the front side of the infrared sensor 14, the front end of the infrared emitting hole 3 slidingly extending out of the front side of the housing 1, and two sets of reinforcing components installed between the housing 1 and the rear cover 6.

[0030] When in use, the display module with an active infrared sensor is quickly assembled through the snap-fit ​​structure between the outer shell 1 and the back cover 6. Specifically, the snap-fit ​​pin 8 on the front side of the back cover 6 snaps into the snap-fit ​​groove 9 on the inner wall of the outer shell 1. The display screen 2 is installed in the mounting groove 13 on the front side of the outer shell 1, and a flexible circuit board 10 is fixed to its rear side. The bottom of the flexible circuit board 10 integrates an infrared sensor 14. The infrared sensor 14 emits and receives infrared signals through the infrared emitting hole 3 at the front end. At the same time, the reinforcing components set between the outer shell 1 and the back cover 6 further enhance the structural stability and ensure the reliable operation of the infrared sensor 14 and the display screen 2.

[0031] The reinforcement components include a pressing block 22. Fixing blocks 20 are fixedly connected to the left and right sides of the front of the rear cover 6. A sliding groove 21 is provided inside the fixing block 20. The pressing block 22 is slidably connected to the sliding groove 21. A telescopic rod 23 is fixedly connected between the front side of the pressing block 22 and the front side of the sliding groove 21. A spring 24 is sleeved on the telescopic rod 23. Sliding grooves 30 are provided on the top and bottom sides of the front of the fixing block 20. Sliding clamps 27 are slidably connected to both sets of sliding grooves 30. Connecting rods 31 are fixedly connected to the rear sides of both sets of sliding clamps 27. Two sets of L-shaped rods 26 are rotatably installed between the left and right sides inside the sliding groove 21. The rear ends of the two sets of connecting rods 31 are respectively hinged to the front ends of the two sets of L-shaped rods 26. Two sets of connecting rods 25 are fixedly connected to the front of the pressing block 22. The front ends of the two sets of connecting rods 25 are respectively hinged to the rear ends of the two sets of L-shaped rods 26. Fixing mechanisms are installed on the left and right sides of the outer shell 1.

[0032] The fixing mechanism includes a plug 33. Slide grooves 32 are provided on both the left and right sides of the outer shell 1. The plug 33 is slidably connected to the slide grooves 32. A clamping groove 28 is provided on the side of the two sets of sliding clamping plates 27 that are close to each other. The end of the plug 33 that is close to the fixing block 20 is slidably connected between the two sets of clamping grooves 28. A limiting block 29 is fixedly connected to the clamping groove 28. A limiting groove 34 is provided on the plug 33. The limiting block 29 is engaged in the limiting groove 34. A pull plate 35 is fixedly connected to the end of the plug 33 that is away from the fixing block 20. A pull groove 36 is provided on the pull plate 35.

[0033] When the reinforcement component is in use, the pressing block 22 is slidably connected in the first groove 21 of the fixing block 20. Its front side is connected to the front side of the first groove 21 through the telescopic rod 23 and the spring 24. When the pressing block 22 is pressed, the spring 24 is compressed. The pressing block 22 drives the L-shaped rod 26 to rotate through the first connecting rod 25. The second connecting rod 31, which is hinged at the front end of the L-shaped rod 26, pushes the sliding clamp 27 to slide in the second groove 30 of the fixing block 20, so that the sliding clamp 27 releases the insert block 33 of the outer shell 1. The insert block 33 is installed on the outer shell 1 through the third groove 32. The limiting groove 34 at its end engages with the limiting block 29 in the clamping groove 28 of the sliding clamp 27, thereby locking the outer shell 1 and the rear cover 6. After the limiting groove 34 disengages from the limiting block 29, the insert block 33 is pulled by the pulling groove 36 on the pulling plate 35 to disengage from the limiting block 29, thereby releasing the fixation and allowing the rear cover 6 to be disassembled.

[0034] An ambient light sensor 4 and a distance sensor 5 are also installed on the top of the outer casing 1, which are used to detect the ambient light intensity and the distance to the object, respectively. The data is transmitted to the control system through the flexible circuit board 10 to realize the brightness adjustment of the display screen 2 or the user proximity sensing function.

[0035] A sealing ring 12 is fitted around the edge of the display screen 2. The sealing ring 12 around the edge of the display screen 2 is wrapped with elastic sealing material to prevent dust and moisture from entering the equipment from the edge of the mounting groove 13, thereby improving the protection performance.

[0036] A heat dissipation vent 7 is provided on the top rear side of the back cover 6. A dustproof net 19 is installed on the heat dissipation vent 7. The heat dissipation vent 7 on the top rear side of the back cover 6 is used to release the heat inside the device. The dustproof net 19 on it prevents dust from entering the housing 1 through the heat dissipation vent 7, thus maintaining a balance between heat dissipation and dust prevention.

[0037] The front side of the back cover 6 is fixedly connected with several reinforcing ribs 18, which improves the impact resistance and bending resistance of the back cover 6 and protects the internal components from external damage.

[0038] Inside the housing 1, behind the display screen 2, is a battery 11 that provides power to the device.

[0039] A temperature sensor 17 is also installed on the flexible circuit board 10 to monitor the internal temperature of the equipment in real time, and the data is fed back to the control system to adjust heat dissipation or trigger the overheat protection mechanism.

[0040] Corner protectors 15 are fixedly connected to the four outer corners of the outer shell 1. The cushioning material absorbs the impact of drops or collisions, reducing the risk of mechanical damage to the four corners of the outer shell 1.

[0041] Working principle: When in use, this display module with an active infrared sensor is quickly assembled via a snap-fit ​​structure between the outer casing 1 and the back cover 6. Specifically, the snap-fit ​​pins 8 on the front side of the back cover 6 snap onto the snap-fit ​​grooves 9 on the inner wall of the outer casing 1. The display screen 2 is installed in the mounting groove 13 on the front side of the outer casing 1, and a flexible circuit board 10 is fixed to its rear side. An infrared sensor 14 is integrated at the bottom of the flexible circuit board 10. The infrared sensor 14 emits and receives infrared signals through the infrared emitting hole 3 at its front end. Simultaneously, it is slidably connected to the sliding groove 21 of the fixing block 20 via a pressing block 22. Its front side is connected to the front side of the sliding groove 21 via a telescopic rod 23 and a spring 24. When the pressing block 22 is pressed, the spring 24 is compressed, and the pressing block 22 is connected via a telescopic rod 23 and a spring 24. Rod 25 drives L-shaped rod 26 to rotate. Connecting rod 31, which is hinged at the front end of L-shaped rod 26, pushes sliding clamp 27 to slide in sliding groove 30 of fixed block 20, so that sliding clamp 27 releases the insert 33 of outer shell 1. Insert 33 is installed on outer shell 1 through sliding groove 32. The limiting groove 34 at its end engages with the limiting block 29 in the clamping groove 28 of sliding clamp 27, thereby locking outer shell 1 and rear cover 6. When the limiting groove 34 disengages from the limiting block 29, the insert 33 is pulled by the pulling groove 36 on the pulling plate 35 to disengage from the limiting block 29, thereby releasing the fixation and disassembling the rear cover 6. This fixing method further enhances the structural stability of the equipment and ensures the reliable operation of infrared sensor 14 and display screen 2.
