Description

Technical Field

[0001] This utility model relates to the field of rotating shafts for intelligent gimbals, and particularly to automatic rotating shafts for intelligent gimbals. Background Technology

[0002] Handheld gimbals (or stabilizers), as sophisticated optical image stabilization devices, are widely used in professional film and television production as well as in consumer photography. Their core function is to use high-precision motor-driven algorithms to counteract hand shake in real time, thus providing a stable shooting platform for cameras, smartphones, and other shooting devices.

[0003] To ensure the screen remains flush with the main unit surface at 0°, forming a clean, unified look, the gimbal frame must be designed with recesses to accommodate the screen and surrounding protrusions (or steps). The presence of these protrusions is essential for maintaining structural strength and overall aesthetics. However, in current technology, to achieve screen tilt adjustment, the industry commonly uses a single-axis rotating hinge structure, where the screen's rotation axis is fixed to one side of the screen assembly's frame. This design is chosen for its internal cable routing, structural simplicity, and cost control, but it also has inherent drawbacks. When the screen rotates around this eccentric axis, its overall movement trajectory is an arc. Due to the screen's offset after rotation, its edges or back panel are prone to mechanical interference with the protrusions on one side of the recess, causing significant inconvenience. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic rotating shaft for a smart gimbal. The structure is ingenious and can realize the rotation and lifting of the screen, thereby avoiding the collision between the screen and the protrusion on the side of the mounting step during the rotation. It can also greatly reduce the gap between the screen and the protrusion on the side of the mounting step, preventing dust and other impurities from entering the mounting groove and affecting the use of precision components such as motors or electronic components. It is convenient and practical.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a shell and a screen. The shell is provided with an installation step, and the installation step is provided with an installation groove. The installation groove is provided with a driving assembly for lifting and flipping the screen. The driving assembly includes a fixed plate fixed in the installation groove, a rack fixedly mounted on the fixed plate, a lifting plate vertically connected to the fixed plate, a rotating bracket rotatably connected to the fixed plate, a drive motor fixedly mounted in the installation groove, a drive bracket fixedly mounted on the fixed plate, a drive screw fixedly mounted at the output end of the drive motor and rotatably connected to the drive bracket, and a drive block that is driven by the drive screw and slidably mounted on the drive bracket. The rotating bracket includes an installation plate for mounting the screen and a rotating cylinder integrally formed with the installation plate. The rotating cylinder rotates... The device is connected within the mounting slot. The fixed plate has a lifting slide groove, and the end of the rotating cylinder away from the mounting plate has a bushing. The bushing is slidably positioned within the lifting slide groove. The lifting plate has a through hole through which the rotating cylinder passes. After passing through the through hole, the rotating cylinder is rotatably connected to the fixed plate via the bushing. The rotating cylinder has a transmission gear that can engage with a rack and pinion drive. The transmission gear and the rack are located between the lifting plate and the fixed plate. The side of the drive block is fixedly connected to the lifting plate via a locking device. The drive block has a screw hole. The drive block drives the drive screw through a drive motor. The drive screw engages with the screw hole to lift the lifting plate and the rotating bracket. During the lifting process, the rotating bracket engages with the rack and pinion drive to rotate the mounting plate and the screen on the mounting plate.

[0006] Furthermore, the aforementioned fixed plate is provided with a side slide groove arranged parallel to the lifting slide groove, and the lifting plate is provided with a side slider adapted to the side slide groove, the side slider being slidably disposed within the side slide groove.

[0007] Furthermore, the aforementioned drive block is provided with a guide hole, and the drive bracket is provided with a guide rod arranged parallel to the drive screw. The drive block is slidably connected to the drive bracket through the drive motor driving the drive screw, the threaded engagement between the drive screw and the screw hole, and the engagement between the guide hole and the guide rod.

[0008] Furthermore, the drive block is provided with an extension plate on its side, the extension plate has a side hole, a connecting screw is provided in the side hole, the lifting plate is provided with a mounting base integrally formed with the lifting plate, the mounting base has a connecting screw hole, the axis of the connecting screw hole is arranged parallel to the lifting slide groove, and the extension plate is fixed on the mounting base by the threaded engagement of the connecting screw and the connecting screw hole on the mounting base.

[0009] Furthermore, the outer wall of the aforementioned rotating cylinder is provided with opposing limiting protrusions, each limiting protrusion being integrally formed with the rotating cylinder. One end of each limiting protrusion is mounted on the mounting plate, and the other end of each limiting protrusion extends along the axis of the rotating cylinder toward the side away from the mounting plate.

[0010] This utility model has positive effects: (1) By setting a drive component in the mounting slot, the drive motor drives the drive screw to rotate, and the drive block slides under the cooperation of the drive screw. During the sliding process, the drive block drives the lifting plate to rise and fall, and during the rising and falling process, the lifting plate drives the rotating bracket to rotate, thereby driving the screen to rise and rotate. The cooperation between the bushing and the lifting slide, as well as the cooperation between the rotating cylinder and the bushing, effectively ensures the synchronous rotation and lifting of the screen, effectively solving the problem of interference between the screen and the boss during the rotation process in the prior art. On the other hand, by raising and lowering the screen, the gap between the screen and the boss is greatly reduced, avoiding dust or other debris from entering the mounting slot and damaging the electronic components in the mounting slot. This ensures the compactness of the overall structure and the safety of the electronic components in the mounting slot. The structure is ingenious, convenient and practical.

[0011] (2) This utility model provides a side slide groove on the fixed plate and a side slider on the lifting plate. The combination of the side slider and the side slide groove ensures the stability of the lifting plate during the lifting process and prevents the lifting plate from rotating along with the rotating drum. It is safe and practical.

[0012] (3) By setting a guide hole on the drive block and a guide rod on the drive bracket, the sliding fit between the guide hole and the guide rod ensures the stability of the drive block during the sliding process.

[0013] (4) By connecting the extension plate and the mounting base, the drive motor drives the drive block, and synchronously drives the lifting plate to rise or fall, thus ensuring the stability of the lifting plate during the lifting process.

[0014] (5) By setting a limiting protrusion on the outer wall of the rotating drum, one end of the limiting protrusion is integrally formed with the mounting plate, and the other end of the limiting protrusion extends to press against the lifting plate, which further ensures the stability of the lifting plate while also ensuring the compactness of the overall structure, making it convenient and practical.

[0027] The working principle of this utility model is as follows: In the initial state, the front end face of screen 2 is flush with the front end face of housing 1, the left side of screen 2 is flush with the left side of housing 1, and the right side of screen 2 is flush with the right side of housing 1. A gap is left between the lower end of screen 2 and the protrusion on the side of mounting step 11. During the lifting process of screen 2, drive motor 37 drives drive screw 38 to rotate. Drive screw 38, through threaded engagement with the screw hole on drive block 30, drives drive block 30 to slide on drive bracket 36. During the sliding process, drive block 30 is guided...
