Description

Technical Field

[0001] This utility model belongs to the field of touch display technology, and in particular relates to a light wave sensing structure for gesture recognition of a touch display. Background Technology

[0002] A gesture recognition optical wave sensing structure is a device that uses optical technology to detect hand gestures, typically used in touchscreens or contactless interactive devices. Its core principle is to capture gesture information through the emission, reflection, and reception of light waves, and then combine this with signal processing algorithms to achieve gesture recognition.

[0003] Existing gesture recognition uses light wave sensing structures to recognize gestures by mounting a gesture recognition sensor on a PCB board. The gesture recognition sensor is mounted on the PCB board through two mounting holes on its surface and a mounting bolt. However, this mounting method can only install gesture recognition sensors with the same inner diameter mounting hole, and cannot adapt to different similar gesture recognition sensors, which causes certain limitations of the touch screen.

[0004] To address these issues, we provide a light wave sensing structure for gesture recognition on a touch display screen. Utility Model Content

[0005] The purpose of this invention is to provide a light wave sensing structure for gesture recognition on a touch screen. This addresses the limitations of existing gesture recognition structures that rely on a gesture sensor mounted on a PCB board. While the gesture sensor is mounted via two mounting holes and screws, this method only accommodates gesture sensors with the same inner diameter mounting hole, making it unsuitable for different or similar gesture sensors and hindering the development of a suitable touchscreen.

[0006] It has certain limitations.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a light wave sensing structure for gesture recognition of a touch screen, comprising a touch screen body, a PCB board inside the touch screen body, a mounting base on the surface of the PCB board, a groove on one side of the mounting base, two support plates movably mounted inside the groove, a locking post fixedly mounted on the upper end of the support plate, clamping rods movably mounted on both sides of the locking post, pressure blocks movably mounted on the surface of the clamping rods, a gesture recognition sensor mounted on the surface of the mounting base, and two mounting holes on the surface of the gesture recognition sensor, the mounting holes being fitted around the outside of the locking post and fitting against the clamping rods, and the upper end of the gesture recognition sensor fitting against the pressure block.

[0009] The present invention is further configured such that movable grooves are provided on both sides of the lower end of the groove, a double-threaded screw is rotatably installed inside the mounting base, movable threaded sleeves are movably sleeved at both ends of the double-threaded screw, a movable block is fixedly installed on one side of the movable threaded sleeve, and the upper end of the movable block passes through the movable groove and is fixedly connected to the support plate. The upper end of the support plate is on the same horizontal line as the upper end of the mounting base.

[0010] The present invention is further configured such that an installation groove is provided inside the locking post, the installation groove is circular, and an adjustment groove is provided in the middle of the inside of the locking post, the adjustment groove being located in the inner circle of the installation groove.

[0011] The present invention is further configured such that adjusting screw sleeves are rotatably installed on both sides inside the mounting groove, one end of the adjusting screw sleeve is movably inserted into the clamping screw, and the two clamping screws located on the same side are movably inserted into the outside of the clamping post and fixedly connected to the same clamping rod.

[0012] The present invention is further configured such that one end of the adjusting screw sleeve is movably inserted into the adjusting groove.

[0013] An internal bevel gear is fixedly installed at this end, and an adjusting rod is rotatably installed inside the adjusting groove. A rotating toothed disc is sleeved on the surface of the adjusting rod, and the rotating toothed disc meshes with the bevel gear.

[0014] The present invention is further configured such that an adjusting screw is rotatably mounted inside the clamping rod, and a clamping screw sleeve is movably sleeved on the outside of the adjusting screw, and the clamping screw sleeve is connected to the pressure block.

[0015] The present invention is further configured such that sliding grooves are provided on both sides of the clamping rod, and a slider passes through the inside of the sliding groove.

[0016] The present invention is further configured such that one end of the adjusting screw is located outside the clamping rod and is equipped with a meshing gear, and a rotating toothed ring is rotatably mounted on the outside of the locking pin, the rotating toothed ring cooperating with the meshing gear.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the user places the gesture recognition sensor on the mounting base. The mounting hole on the surface of the gesture recognition sensor is fitted onto the clamping post. The user rotates the adjusting rod, which drives the rotating gear to rotate. The rotating gear drives multiple adjusting screw sleeves to rotate synchronously through the bevel gear. Under the action of the thread, the clamping screw moves along the adjusting screw sleeve to the outside of the clamping post. The clamping screw drives the clamping rod to move. The clamping rod fits against the inner wall of the mounting hole, which is convenient for clamping gesture recognition sensors of different diameters. At the same time, the pressure block fits against the upper end of the gesture recognition sensor, which is convenient for limiting the gesture recognition sensor and preventing the gesture recognition sensor from shaking.

[0019] 2. In this invention, when the user moves the clamping rod to its shortest distance from the locking post, the meshing gear at the upper end of the clamping rod engages with the rotating gear ring on the surface of the locking post. The user rotates the rotating gear ring, which, through the meshing gear, drives multiple adjusting screws to rotate synchronously. The clamping sleeve, under the action of the threads, moves along the adjusting screws. The clamping sleeve, through the slider, drives the pressure block to move, facilitating the adjustment of the distance between the pressure block and the support plate, and making it convenient to clamp gesture recognition sensors of different thicknesses.

[0020] This allows the device to be adapted to different similar gesture recognition sensors, enhancing the effectiveness of the light wave sensing structure. Attached Figure Description

[0030] The groove 310 has two support plates 330 movably mounted inside. A locking post 340 is fixedly mounted on the upper end of each support plate 330. Clamping rods 350 are movably mounted on both sides of the locking post 340. Pressure blocks 355 are movably mounted on the surface of the clamping rods 350. A gesture recognition sensor 400 is mounted on the surface of the mounting base 300. The gesture recognition sensor 400 has two mounting holes 410 on its surface, which are fitted onto the outside of the locking post 340 and fit against the clamping rods 350. The upper end of the gesture recognition sensor 400 fits against the pressure block 355. An installation groove 341 is formed inside the locking post 340. The installation groove 341 is annular. An adjustment groove 342 is formed in the middle of the inside of the locking post 340, located within the inner circle of the installation groove 341. Adjusting screw sleeves 343 are rotatably installed on both sides inside. One end of the adjusting screw sleeve 343 is movably inserted into the clamping screw 344. Two clamping screws 344 located on the same side are movably inserted into the outside of the locking post 340 and are fixedly connected to the same clamping rod 350. One end of the adjusting screw sleeve 343 is movably inserted into the inside of the adjusting groove 342 and a bevel gear 345 is fixedly installed at this end. An adjusting rod 347 is rotatably installed inside the adjusting groove 342. A rotating gear 346 is sleeved on the surface of the adjusting rod 347. The bevel gear 345 meshes with the bevel gear 345.

[0031] In this embodiment, the user places the gesture recognition sensor 400 on the mounting base 300. The mounting hole 410 on the surface of the gesture recognition sensor 400 is fitted onto the clamping post 340. The user rotates the adjusting rod 347, which drives the rotating gear 346 to rotate. The rotating gear 346 drives multiple adjusting sleeves 343 to rotate synchronously through the bevel gear 345. Under the action of the thread, the clamping screw 344 moves along the adjusting sleeve 343 to the outside of the clamping post 340. The clamping screw 344 drives the clamping rod 350 to move. The clamping rod 350 fits against the inner wall of the mounting hole 410, which is convenient for clamping gesture recognition sensors 400 of different diameters. At the same time, the pressure block 355 fits against the upper end of the gesture recognition sensor 400, which is convenient for limiting the gesture recognition sensor 400 and preventing the gesture recognition sensor 400 from shaking.

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a light wave sensing structure for gesture recognition of a touch screen. Movable grooves 322 are provided on both sides of the lower end of the groove 310. A double-threaded screw 320 is rotatably installed inside the mounting base 300. Movable sleeves 321 are movably sleeved at both ends of the double-threaded screw 320. A movable block 323 is fixedly installed on one side of the movable sleeve 321. The upper end of the movable block 323 passes through the movable groove 322 and is fixedly connected to the support plate 330. The upper end of the support plate 330 and the upper end of the mounting base 300 are on the same horizontal line.

[0033] When the user rotates the double-threaded screw 320, the movable screw sleeve 321 moves in the opposite or disjointed direction as the double-threaded screw 320 moves under the action of the thread. The movable screw sleeve 321 drives the support plate 330 and the locking post 340 to move through the movable block 323, so as to adapt to the gesture recognition sensor 400 with different distances of the mounting hole 410.

[0034] like Figures 2 to 4 As shown, this embodiment provides a light wave sensing structure for gesture recognition of a touch screen. An adjusting screw 352 is rotatably installed inside the clamping rod 350. A clamping sleeve 354 is movably sleeved on the outside of the adjusting screw 352. The clamping sleeve 354 is connected to the pressure block 355. Slide grooves 356 are opened on both sides of the clamping rod 350. A slider 357 passes through the inside of the slide groove 356. The two ends of the slider 357 are fixedly connected to the pressure block 355 and the clamping sleeve 354, respectively. One end of the adjusting screw 352 is located on the outside of the clamping rod 350 and is equipped with a meshing gear 353. A rotating gear ring 351 is rotatably installed on the outside of the locking post 340. The rotating gear ring 351 cooperates with the meshing gear 353.

[0035] In this embodiment, when the user moves the clamping rod 350 to the shortest distance from the locking post 340, the meshing gear 353 at the upper end of the clamping rod 350 meshes with the rotating gear ring 351 on the surface of the locking post 340. The user rotates the rotating gear ring 351, which drives multiple adjusting screws 352 to rotate synchronously through the meshing gear 353. Under the action of the thread, the clamping sleeve 354 moves along the adjusting screw 352. The clamping sleeve 354 drives the pressure block 355 to move through the slider 357, which facilitates the adjustment of the pressure block.

[0036] The distance between 355 and the support plate 330 facilitates the clamping of gesture recognition sensors 400 of different thicknesses, making the overall device compatible with different similar gesture recognition sensors 400 and enhancing the effectiveness of the light wave sensing structure.
