Description

Technical Field

[0001] This utility model belongs to the technical field of photographic auxiliary equipment, specifically a mobile phone holder device for taking photos of voucher pages. Background Technology

[0002] With the rapid development of the mobile phone holder industry, various types of mobile phone holders have been widely used in daily life. However, in specific application scenarios, such as taking photos of vouchers, the functions and designs of existing mobile phone holders still have significant shortcomings. Most mobile phone holders on the market currently focus on fixation and support as their core functions, making it difficult to meet users' diverse needs in terms of flexibility, stability, and ease of operation. This limitation leads to a poor user experience and significantly reduced work efficiency in scenarios where the position or angle of the phone needs to be frequently adjusted.

[0003] A search revealed a patent with publication number CN114025036B (published on July 7, 2023) that proposes a phone holder design including a phone support module and a document support module. It uses a ball screw transmission system to position and support the document, and a spring-loaded pressure plate structure to hold the phone. While this design can alleviate the instability of angle and distance during document scanning due to prolonged operation, its complex structure and cumbersome operation, especially in scenarios involving frequent page turning for document photography, require users to constantly adjust the relative position of the phone and document, increasing the operational burden. Furthermore, this design does not adequately consider the need for rapid perspective switching during page turning and lacks flexible angle adjustment functionality, making it difficult to meet the requirements of efficient shooting.

[0004] Another patent, CN110557487B (published on November 5, 2024), uses a suction cup structure. It achieves suction and release through the cooperation of an elastic element and a cover, allowing for one-handed operation to pick up and put down the phone. While this design improves the ease of use of the phone holder, its fixed suction method limits the phone's flexible movement and multi-angle adjustment capabilities when used for taking photos of document pages. Furthermore, this design is primarily designed for flat suction scenarios and does not fully consider the need for frequent switching between landscape and portrait modes during shooting, thus potentially leading to insufficient adaptability in practical applications.

[0005] In summary, traditional phone holders on the market generally suffer from insufficient flexibility, poor stability, and limited ease of operation when dealing with document flipping and shooting scenarios, failing to meet users' demands for efficiency, flexibility, and adaptability. Therefore, there is an urgent need for a new type of phone holder device to overcome these shortcomings and provide a more efficient, flexible, and scenario-specific solution. Utility Model Content

[0038] This utility model provides a mobile phone holder device for photographing vouchers. Through the coordinated action of the support base 1, rotation adjustment module, angle positioning module, and document holder, it achieves rapid adjustment and precise locking of the mobile phone clamping component 3 at multiple angles and positions. Simultaneously, the design of the document holder ensures the stability of the voucher document during the photographing process. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 6As shown, the overall structure of this utility model includes a support base 1, a rotating disk 2 disposed on the top of the support base 1, and a mobile phone clamping assembly 3 connected to the rotating disk 2. The rotating disk 2 is driven by a first driving device to achieve horizontal rotation, and a gear ring 5 is fixedly disposed on its outer periphery. The gear ring 5 meshes with a rotation driving gear 4, thus forming the core part of the rotation adjustment module. The rotation driving gear 4 is driven to rotate by a second driving device 6, causing the rotating disk 2 to rotate horizontally, so that the mobile phone clamping assembly 3 can be aligned with different shooting angles or positions in sequence. The angle positioning module includes an angle adjusting arm 7, a limiting locking member 8, and an angle driving unit 9. One end of the angle adjusting arm 7 is hinged to the mobile phone clamping assembly 3, and the other end is hinged to the rotating disk 2. The angle driving unit 9 is used to drive the angle adjusting arm 7 to swing around its hinge point, and the limiting locking member 8 locks the angle adjusting arm 7 at the target angle. The document holder includes a holder support frame 10, several adjusting rods 11, and a document clamping module 12. The adjusting rods 11 are mounted on the holder support frame 10 via adjusting sliders 13. The adjusting sliders 13 allow the adjusting rods 11 to be close together or far apart, forming a folder holding channel to accommodate documents of different sizes. The top of the folder holding channel is set as a shooting position, and the document clamping module 12 is movably disposed within the folder holding channel to clamp the document into the shooting position.

[0040] In the specific implementation process, such as Figures 1 to 6 As shown, the rotary drive gear 4 includes a gear body 20, a bearing seat 21, and a third drive device 22. The gear body 20 is rotatably disposed below the gear ring 5, and the bearing seat 21 is fixedly disposed at the bottom of the gear body 20. The third drive device 22 is used to drive the gear body 20 to rotate. The outer periphery of the gear body 20 is provided with toothed portions that mesh with the internal teeth of the gear ring 5. When the third drive device 22 is activated, the gear body 20 rotates, and through the meshing action of the toothed portions with the gear ring 5, it drives the rotating disk 2 to rotate horizontally. The top surface of the rotating disk 2 is provided with a mounting hole, and the inner side of the mounting hole is provided with a positioning boss. A mounting groove is formed between the positioning boss and the mounting hole for mounting the mobile phone clamping component 3.

One end of the main adjustment arm is hinged to the mobile phone clamping assembly 3, and one end of the secondary arm is hinged to the rotating disk 2. The angle adjustment power source drives the main adjustment arm to swing around its hinge point. A limiting locking member 8 is located at the other end of the main adjustment arm to lock it at the target angle. The angle drive unit 9 includes a drive motor, a transmission gear, and an angle sensor. The drive motor is fixedly mounted on the bottom of the rotating disk 2, the transmission gear is connected to the hinge point of the angle adjustment arm 7, and the angle sensor detects the swing angle of the angle adjustment arm 7. In addition, the angle positioning module also includes an angle limiting component, such as... Figure 6 As shown, the angle limiting assembly includes a limiting block 18 and a limiting adjusting bolt 19. The limiting block 18 is adjustablely disposed on the outside of the rotating disk 2 and is vertically opposite to the angle adjusting arm 7. The limiting adjusting bolt 19 is used to adjust the height of the limiting block 18. When the angle adjusting arm 7 is driven to swing to the target angle by the angle driving unit 9, the limiting block 18 abuts against the surface of the angle adjusting arm 7 and locks its position, thereby ensuring the angular stability of the mobile phone clamping assembly 3.

[0042] like Figures 1 to 6 As shown, a guide rail is vertically installed on the side wall of the bracket support frame 10. An adjusting slider 13 slides along the guide rail, and a locking bolt 24 is threadedly connected between the adjusting slider 13 and the guide rail. One end of the adjusting rod 11 is fixedly connected to the outer periphery of the adjusting slider 13. A fixing stud 25 is installed on the top of the adjusting slider 13, and an adjusting groove 26 is installed on the surface of the other end of the adjusting rod 11. The adjusting groove 26 moves along the fixing stud 25, and a locking nut is installed between the fixing stud 25 and the surface of the adjusting rod 11. By adjusting the movement of the adjusting slider 13 and adjusting the adjusting groove 26, the spacing between the adjusting rods 11 can be flexibly changed to accommodate documents of different sizes. The document clamping module 12 includes a clamping movable plate 14 and a clamping power source 15. The clamping movable plate 14 is movably mounted on several adjusting rods 11. The clamping movable plate 14 is provided with clearance grooves for the adjusting rods 11 to pass through. The clamping power source 15 is used to drive the clamping movable plate 14 to move vertically within the document holding channel, thereby clamping the document into the shooting position. Figures 1 to 6As shown, the document clamping module 12 also includes an auxiliary clamping strip 16 and an elastic buffer 17. The auxiliary clamping strip 16 is driven by a clamping lifting power source and is movably positioned above the shooting position. The top of the elastic buffer 17 is provided with a pair of connecting ears, which are respectively hinged to the two sides of the bottom of the auxiliary clamping strip 16. The elastic buffer 17 is used to drive the auxiliary clamping strip 16 to swing up and down. The elastic buffer 17 includes a buffer spring 27 and a buffer rod 28. The buffer rod 28 is vertically movably positioned on one side of the auxiliary clamping strip 16, and the buffer spring 27 is sleeved on the outer periphery of the buffer rod 28. The side of the connecting ear is provided with a snap-fit ​​protrusion 29, and the bottom end of the buffer rod 28 is provided with a snap-fit ​​groove 30 that cooperates with the snap-fit ​​protrusion 29. The snap-fit ​​protrusion 29 is embedded in the snap-fit ​​groove 30, and the outer contour of the snap-fit ​​protrusion 29 is arc-shaped. Through the above design, the auxiliary clamping strip 16 can apply uniform pressure to the voucher document under the action of the elastic buffer 17, avoiding positional shift caused by page turning, thereby improving the accuracy and consistency of shooting.

[0043] In practical applications, the user first vertically stacks the document to be photographed in the document holding channel and adjusts the spacing between the adjusting rods 11 using the adjusting slider 13 and the adjusting slot 26 to fit the document size. Then, the user activates the clamping power source 15, driving the clamping movable plate 14 downwards to press the document into the shooting position. Simultaneously, the auxiliary clamping bar 16, under the action of the elastic buffer 17, applies additional pressure to the document, ensuring its stability during shooting. Next, the user controls the second driving device 6 and the third driving device 22 to drive the rotating disk 2 to rotate horizontally, aligning the phone clamping assembly 3 with different shooting angles or positions. During this process, the angle driving unit 9 drives the angle adjusting arm 7 to swing according to the user's instructions, adjusting the tilt angle of the phone clamping assembly 3, and locking the target angle through the limiting locking member 8 and the angle limiting component. Finally, the user completes the page-turning and shooting operation of the document using the phone clamping assembly 3.

[0044] In summary, this invention, through the synergistic effect of the rotation adjustment module and the angle positioning module, achieves multi-angle rapid adjustment and precise locking of the mobile phone clamping component 3, significantly improving the user's operational convenience and shooting efficiency in document flipping and shooting scenarios. The document holder's adjustment method is flexible and efficient, adaptable to document documents of different sizes, and has wider applicability. In addition, the optimized design of the document clamping module 12 ensures the stability of the document during shooting, avoiding positional shifts caused by page flipping, thereby improving the accuracy and consistency of shooting.
