Description

Technical Field

[0001] The present invention relates to the field of earphone model customization, in particular to a three-dimensional scanning device for earphone models. Background Art

[0002] Custom earphones are made with a custom-made earphone shell based on the shape of your ear canal. Because they are tailored to the shape of your ear canal, they fit perfectly within it, effectively isolating it from external sounds. They are also very comfortable to wear and don't easily fall off.

[0003] When making custom headphones, a scanning device is needed to scan and photograph the customer's ears. Three-dimensional modeling is then performed based on the photograph to create a headphone model. Existing scanning and photography methods usually involve manually holding a scanner at the human ear to scan and photograph it. Manual handheld photography can be tiring and cause arm pain over long periods of time. Furthermore, the customer's head is prone to shaking during photography, which can affect the scanning and photography results.

[0004] Therefore, the present invention provides a three-dimensional scanning device for a headphone model to solve the problems raised in the above background technology. Summary of the Invention

[0023] In this embodiment, the fixing mechanism includes a rocker 8, a bidirectional threaded rod 9, a sliding frame 10, a limit frame 11, a fixing block 12 and a spring 13; the fixing mechanism can fix the user's head to prevent the user's head from shaking and affecting the scanning effect when scanning the user's ears.

[0024] In this embodiment, the limiting frames 11 are fixedly connected to the left and right fixed frames 3, and the bidirectional threaded rods are rotatably connected to the left and right fixed frames 3. The sliding frames 10 are located on the left and right sides of the surface of the limiting frames 11. The sliding frames 10 are slidably connected to the limiting frames 11, and the limiting frames 11 are threadedly engaged with the bidirectional threaded rods 9. When the bidirectional threaded rods 9 rotate, the limiting frames 11 can drive the left and right sliding frames 10 to move simultaneously toward or away from each other.

[0025] In this embodiment, the rocker 8 is fixedly connected to the bidirectional threaded rod. The fixed block 12 is slidably connected to the sliding frame 10, and multiple springs 13 are evenly fixedly connected to the surface of the fixed block 12. The other end of the spring 13 is fixedly connected to the sliding frame 10. By shaking the rocker 8, the bidirectional threaded rod 9 can be easily driven to rotate. By the bidirectional threaded rod 9 and the sliding frame 10 moving, the sliding frame 10 can drive the fixed block 12 inside it to move. When the fixed block 12 contacts the user's head, it can slightly fix the head and prevent it from shaking. The spring 13 can also provide a buffering effect for the fixed block 12 on the head, preventing the fixed block 12 from exerting excessive force and damaging the head.

[0026] In this embodiment, the adjustment mechanism includes a turntable 14, a worm 15, a worm gear 16, a rack 17, a gear 18, a motor 19, a slider 20, and a second cylinder 21. The adjustment mechanism can be used to adjust the scanner 5 to a suitable position, allowing the scanner 5 to accurately scan the user's ear.

[0027] In one embodiment, the worm gear 16 is fixedly connected to the rear end face of the rotating frame 4, the worm 15 is engaged with the worm gear 16 and the worm gear 15 is rotationally connected to the support frame 2, and the turntable 14 is fixedly connected to the worm gear 15; by rotating the turntable 14, the worm gear 15 can be driven to rotate, and when the worm gear 15 rotates, the worm gear 16 can be driven to rotate, and when the worm gear 16 rotates, the rotating frame 4 can be driven to rotate. The rotating frame 4 cannot rotate freely under the action of the worm gear 16 and the worm gear 15.

[0028] In one embodiment, a slide groove 22 is provided within the turret 4, and a slider 20 is slidably connected to the slide groove 22. A motor 19 is fixedly connected to the slider 20, and the output shaft of the motor 19 is fixedly connected to the gear 18. A rack is fixedly connected to the surface of the turret 4, and the gear 18 meshes with the rack. One end of a second cylinder 21 is fixedly connected to the slider 20, and the other end of the second cylinder 21 is fixedly connected to the scanner 5. When the motor 19 drives the gear 18 to rotate, the gear 18, under the action of the rack, can drive the motor 19 and the slider 20 to slide within the slide groove 22. As the slider 20 slides, the second cylinder 21 can drive the scanner 5 to the appropriate scanning position.

[0029] In this embodiment, a plurality of telescopic rods 23 are evenly and fixedly connected to the bottom end of the seat 6, and the bottom end of the telescopic rod 23 is fixedly connected to the base plate 1; the telescopic rod 23 can limit the position of the seat 6, and can effectively improve the stability of the seat 6.

[0030] The working principle of the present invention is:

[0031] To use this device, the user who needs to be scanned first sits on seat 6. Then, the first cylinder 7 is activated to raise or lower seat 6. When the user's head is properly positioned between the left and right fixed blocks 12, the first cylinder 7 is stopped, and the joystick 8 is then cranked to rotate the bidirectional threaded rod 9. As the bidirectional threaded rod 9 rotates, the left and right sliding frames 10, under the action of the stop frame 11, simultaneously move the fixed blocks 12 toward each other. Once the left and right fixed blocks 12 secure the user's head, the joystick 8 is stopped. Then, the motor 19 is activated to simultaneously rotate the turntable 14. This rotation of the motor 19 drives the gear 18. The rotation of the gear 18, driven by the rack, drives the slider 20 to slide within the slide groove 22. As the slider 20 slides, the scanner 5 is moved via the second cylinder 21. Simultaneously, the turntable 14 rotates the worm 15, which in turn drives the worm gear 16, which in turn drives the rotating frame 4. The rotating frame 4 and the slider 20 can move the scanner 5 to the most accurate scanning position, and then the second cylinder 21 is activated to move the scanner 5 closer to the user's ear. When the scanner 5 moves to the appropriate position, the second cylinder 21 is stopped, and the scanner 5 is started to scan and photograph the user's ear. After scanning one ear, the second cylinder 21 is activated to return the scanner 5 to its original position, and then the motor 19 is started and the turntable 14 is rotated to move the scanner 5 to the scanning position of the other ear. The second cylinder 21 is then activated again to move the scanner 5 closer to the other ear. When the scanner 5 moves to the appropriate position, the second cylinder 21 is stopped, and the scanner 5 is started to scan and photograph the other ear.
