Description

Technical Field

[0001] This utility model relates to the field of document scanner technology, and more specifically, to an electric folding document scanner. Background Technology

[0002] A high-speed document scanner, also known as a document scanner, has OCR text recognition capabilities. It can recognize and convert scanned images into editable Word documents. It can also perform operations such as taking photos, recording videos, copying, paperless faxing, creating e-books, and trimming and straightening edges. Compared to traditional scanners that take more than 10 seconds to scan a document, high-speed document scanners can effectively improve work efficiency and have been widely used in various departments of enterprises, government agencies, and educational institutions.

[0003] For example, a document scanner disclosed in Chinese patent CN220554040U includes: a support part; a damping shaft having a first connecting section and a second connecting section arranged opposite to each other, the first connecting section and the second connecting section being hinged together, the first connecting section being connected to the support part; a rotating part connected to the second connecting section, the rotating part being rotatably connected to the support part via the damping shaft; and a camera assembly disposed on the rotating part, the camera assembly being able to rotate via the rotating part to adjust the shooting angle. The document scanner provided by this utility model can solve the problem that the camera angle of existing document scanners cannot be adjusted to meet different shooting needs. However, the rotating part of the document scanner provided by this utility model is rotatably connected to the support part via the damping shaft, and the unfolding operation is all done manually. Furthermore, when the rotating part is accidentally touched or subjected to other external forces, the rotating part will rotate along with the damping shaft, causing the shooting angle to deviate from the predetermined position, resulting in insufficient stability. It also requires manual readjustment to return to the desired shooting angle, making the operation cumbersome. Utility Model Content

[0021] An electric folding document scanner includes a base, a support rod, and a rotating rod with a camera module. The bottom end of the support rod is connected to the base, and the top end of the support rod is movably connected to the rotating rod. It also includes a worm gear drive assembly, which includes a worm, a turbine, and a drive motor. The rotating rod has an inner cavity, and the drive motor and worm are disposed within the inner cavity. The output end of the drive motor is connected to the worm gear via a transmission connection. The turbine has turbine shafts at both ends, and the turbine is fixedly mounted on the top end of the support rod via the turbine shafts. The worm meshes with the turbine.

[0022] In use, the drive motor provides power to the worm gear, which then transmits power to the worm wheel through meshing, automatically unfolding the rotating rod or folding the rotating rod and support rod for storage. This completely replaces the manual unfolding process, making operation simple and convenient. The worm gear drive assembly allows for angle adjustment between the rotating rod and support rod, meeting various shooting needs, such as shooting three-dimensional objects or tilting documents. Users do not need to manually rotate the rotating rod, reducing operational steps and improving work efficiency. The worm gear drive assembly's self-locking feature ensures that the rotating rod remains stable after being adjusted to the desired angle. When the motor stops rotating, the worm wheel is locked, preventing the worm gear from being driven to rotate in the opposite direction by external force, thus avoiding angle changes due to accidental contact and ensuring high stability.

[0023] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: refer to Figures 1 to 5 An electric folding document scanner includes a base 10, a support rod 20, a rotating rod 30 with a camera module 313, and a worm gear drive assembly 40. The top end of the support rod 20 is connected to the worm gear drive assembly 40, and the bottom end of the support rod 20 is connected to the base 10. The rotating rod 30 can be folded and positioned on one side of the support rod 20 by the worm gear drive assembly 40.

[0024] The rotation range of the rotating rod 30 relative to the support rod 20 is between 0° and 90°. Multiple rotation ranges allow the electric folding document scanner to meet different shooting needs and can be flexibly adjusted according to requirements. Furthermore, the rotation range of 0° to 90° can prevent the rotating rod 30 from rotating excessively, avoid product damage, and extend its service life.

[0025] The worm drive assembly 40 includes a worm 41, a turbine 42, and a drive motor 43. The rotating rod 30 has an inner cavity 31, and the drive motor 43 and the worm 41 are disposed in the inner cavity 31, making the entire device more compact and saving space. The output end of the drive motor 43 is connected to the worm 41 for transmission. The two ends of the turbine 42 are provided with turbine shafts 421. The turbine 42 is fixedly mounted on the top of the support rod 20 through the turbine shafts 421, and the worm 41 meshes with the turbine 42.

[0026] The output end of the drive motor 43 is connected to the worm gear 41. When the drive motor 43 starts, it drives the worm gear 41 to rotate. The worm gear 41 meshes with the fixed turbine 42 and revolves around the axis of the turbine 42 under the action of the meshing reaction force. This causes the rotating rod 30 to rotate around the turbine shaft 421 relative to the support rod 20, thereby realizing the angle adjustment of the rotating rod 30. The worm gear 41 has a self-locking characteristic. When the drive motor 43 stops rotating, the turbine 42 is locked and cannot be driven to rotate by external force. This ensures the structural stability and load-bearing capacity after deployment and prevents accidental rotation. Its large transmission ratio characteristic allows the use of a small motor to achieve high torque output. The turbine 42 is fixedly mounted on the top of the support rod 20 through the turbine shaft 421, ensuring the stability of the turbine 42 during rotation.

[0027] The support rod 20 is connected to the rotating rod 30 at one end and is provided with a mounting part 21. The inner side wall of the mounting part 21 is provided with a mounting hole 211. Both ends of the turbine shaft 421 pass through the mounting hole 211 and are fixed on the support rod 20.

[0028] In this embodiment, one end of the turbine shaft 421 is a D-shaped shaft, which matches the shape of the mounting hole 211 to ensure the stability of the transmission. The other end of the turbine shaft 421 is provided with a mounting plate, which is fixedly connected to the mounting part 21. When the drive motor 43 drives the worm 41 to rotate, the worm 41 meshes with the fixed turbine 42 and revolves around the axis of the turbine 42 under the action of the meshing reaction force, thereby causing the rotating rod 30 to rotate relative to the support rod 20.

[0029] The mounting part 21 is also provided with an arc groove 212, and the rotating rod 30 is provided with an arc slider 32 that cooperates with the arc groove 212. During the process of adjusting the angle of the rotating rod 30 relative to the support rod 20, the arc slider 32 rotates and slides in the arc groove. Both the arc slider 32 and the arc groove 212 have smooth arc surfaces, which makes the rotation of the rotating rod 30 smoother, reduces friction, and makes it faster when unfolding or folding.

[0030] The support rod 20 is provided with a folding groove 22. The rotating rod 30 can be rotatably disposed in the folding groove 22 through the worm gear drive assembly 40. The folding groove 22 matches the size of the rotating rod 30, and the rotating rod 30 can be completely stored in the support rod 20 to prevent it from being damaged by external forces in the folded state, thus providing strong protection. One end of the folding groove 22 is provided with a camera module groove 23. The depth of the camera module groove 23 is slightly deeper than the depth of the folding groove 22. When the rotating rod 30 is placed in the folding groove 22, the camera module 313 on the rotating rod 30 is placed in the camera module groove 23. The camera module groove 23 is specifically used to store the camera module 313 on the rotating rod 30, ensuring that the camera module 313 can be properly protected in the folded state and avoid being hit or scratched by the outside world. When the rotating rod 30 is folded and stored, the camera module 313 is just embedded in the camera module groove 313, which improves the overall aesthetics of the product.

[0031] The electric folding document scanner also includes a protective housing 50. The inner side of the protective housing 50 is provided with a slide rail 51, and the two sides of the support rod 20 are provided with slide grooves 25 that match the slide rail 51. The protective housing 50 can provide a certain degree of protection for the support rod 20, improve its durability and protective performance, and through the design of the slide rail 51 and the slide grooves 25, the protective housing 50 can be easily removed or installed from the support rod 20, allowing users to easily check whether the turbine shaft 421 is fixedly installed, as well as the status of other internal components. During maintenance, the removability of the protective housing 50 can greatly reduce maintenance time and workload, and improve the maintenance efficiency of the product.

[0032] The inner cavity 31 of the rotating rod 30 is provided with multiple sets of limiting blocks 311, and the limiting blocks 311 form a limiting slot. The drive motor 43 is installed in the limiting slot to form a locking connection, which can ensure the stability of the drive motor 43 in the inner cavity 31 of the rotating rod 30 and prevent the drive motor 43 from shifting due to vibration during operation, thereby improving the reliability and service life of the product.

[0033] The base 10 is provided with a fixing hole 11, an adjustment knob 12 and a data connection port 13. The bottom end of the support rod 20 is fixed on the fixing hole 11. The adjustment knob 12 can adjust the brightness of the flash module 312, which is simple and convenient to use. The data connection port 13 facilitates the connection of the product with external devices, such as computers and printers, which facilitates data transmission and product maintenance.

[0034] The bottom end of the support rod 20 is provided with a fixing shaft 24. The support rod 20 is fixed to the fixing hole 11 of the base 10 through the fixing shaft 24. The design of the fixing shaft 24 and the fixing hole 11 makes the connection and disassembly between the support rod 20 and the base 10 very convenient. Users can quickly install or disassemble the support rod 20 as needed, which facilitates the maintenance and cleaning of the product.

[0035] In another embodiment, the fixed shaft 24 at the bottom end of the support rod 20 is movably connected to the base 10. The support rod 20 can be rotated relative to the base 10, achieving a 360-degree rotation. This allows the support rod 20 to be adjusted at multiple angles according to the user's needs, improving the product's flexibility and applicability.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
