[0001] This utility model belongs to the technical field of shooting auxiliary equipment, and in particular relates to a stabilizing shooting aid. Background Technology

[0002] In daily life, people frequently use mobile phones, digital cameras, and other shooting devices to take photos or shoot short videos. To assist in using these devices, shooting aids have appeared on the market. Existing shooting aids mainly consist of a handheld part for the user to hold and a mounting base for placing the shooting equipment. The mounting base and handheld part are typically connected by a damped rotation mechanism. By rotating the mounting base, the angle of the shooting equipment can be adjusted to achieve better shooting results. However, in actual use, it has been found that existing shooting aids still have at least the following problems: Firstly, the structure has poor stability. After long-term use or in extreme weather (such as strong winds), the damping at the connection between the handheld part and the fixed base will gradually weaken or even fail, causing the shooting equipment to easily deflect and affecting normal shooting operations.

[0003] Secondly, it lacks image stabilization, and cannot effectively compensate for dynamic offset caused by unstable user grip during shooting, resulting in shaky footage and affecting shooting quality. Utility Model Content

The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0022] It should be noted that when a module is considered to be "connected" to another module, it can be directly connected to the other module, or there may be an intervening module present. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. Furthermore, the terms "center," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] See appendix Figure 1 - Appendix Figure 10 A stabilizing shooting aid includes a handheld part 1, a fixed base 2, a drive mechanism 3, a positioning module 4, and a control unit 5. The handheld part 1 is for the user to hold, and a support platform 10 is connected to the handheld part 1. The fixed base 2 is rotatably connected to the support platform 10 and is used to place the shooting device P. The drive mechanism 3 is mounted on the support platform 10 and drivenly connected to the fixed base 2 to drive the fixed base 2 to rotate. The positioning module 4 is fixedly mounted on the fixed base 2 to identify the angular offset of the shooting device P relative to the horizontal direction. The control unit 5 is installed in the handheld part 1 and electrically connected to the drive mechanism 3 and the positioning module 4. The control unit 5 can control the drive mechanism 3 to drive the fixed base 2 to rotate for dynamic compensation based on the signal fed back by the positioning module 4.

[0024] Specifically, during use, the user holds the handheld part 1 and fixes the shooting device P on the fixed base 2. After the positioning module 4 senses the current position of the fixed base 2 and the shooting device P, it will send a signal to the control unit 5. The control unit 5 will then control the drive mechanism 3 to rotate the fixed base 2, so that the shooting device P is in a vertical position, a horizontal position, or a specific angle position to meet the user's normal usage needs. After the position of the shooting device P is adjusted, the drive mechanism 3 maintains its current operating state so that the fixed base 2 remains stably stationary in its current position.

[0025] During the shooting process, as the user's arm movements or body movements occur, the shooting device P will also move accordingly. If the fixed base 2 and the shooting device P are tilted relative to the horizontal plane due to reasons such as the user's hand tremors, the positioning module 4 can sense that the shooting device P has an angular velocity and / or angle around the rotation center of the fixed base 2. This allows it to quickly identify the offset direction and angular offset of the shooting device P mounted on the fixed base 2, and simultaneously send a feedback signal to the drive mechanism 3. The drive mechanism 3 then generates a counter-torque of a similar magnitude to drive the fixed base 2 to rotate in the opposite direction at a suitable angle, thereby restoring the fixed base 2 and the shooting device P to their original angular positions. Since the positioning module 4 and the drive mechanism 3 are continuously running, dynamic compensation for the shooting device P can be achieved, ensuring that the shooting device P remains at the preset angular position throughout the entire shooting process.

[0026] After use, control the drive mechanism 3 via the control unit 5 to move the fixed base 2 to its initial position, and then remove the phone from the fixed base 2.

[0027] In summary, this utility model provides a rotatable fixed base 2 for placing the shooting device P on the support platform 10 of the grip portion, and a drive mechanism 3 for driving the fixed base 2 to rotate by installing a drive mechanism 3 on the support platform 10. The support platform 10 directly supports the fixed base 2, while the drive mechanism 3, connected to the fixed base 2, also provides partial support. Therefore, it provides dual support to the fixed base 2 during shooting, effectively reducing the impact of external forces on the fixed base 2, lowering the possibility of deflection, and improving structural stability. Furthermore, by installing a positioning module 4 on the fixed base 2 in conjunction with the drive mechanism 3, it can dynamically compensate for the offset of the fixed base 2 and the shooting device P during shooting, thus providing image stabilization and effectively optimizing the shooting effect, improving the overall user experience.

[0028] It should be noted that the shooting device P can be a mobile phone, tablet computer, camera or other product with shooting function. Due to the variety of types, this utility model does not limit it. In addition, when using different products, the size of the handheld part 1 and the fixed base 2 can be adjusted accordingly to maintain compatibility.

[0029] See appendix Figure 1 - Appendix Figure 4 The shooting device P has a built-in magnetic ring or an external magnetic sheet (not shown in the figure). The mounting base 2 is equipped with a magnetic ring 21, which can be used to attract the magnetic ring or the magnetic sheet. This design can attract and fix the shooting device P to the mounting base 2, and also facilitates the removal and placement of the shooting device P.

[0030] Furthermore, the shooting device P also has a built-in magnetic block (not shown in the figure) or an external magnetic block (not shown in the figure), and a magnetic block 22 is also installed on the fixed base 2, which can attract the magnetic block accordingly; this design can limit the rotation of the shooting device P on the fixed base 2, so as to further improve the placement stability of the shooting device P.

[0031] It should be noted that, in addition to using magnetic attraction to mount the shooting device P onto the mounting base 2, in some other embodiments, the mounting base 2 can also use other fixing structures to place the shooting device P. For example, the mounting base 2 may be provided with spring clips (not shown in the figure) for clamping and fixing the shooting device P, or the mounting base 2 may be provided with a locking cavity (not shown in the figure) for engaging and fixing the shooting device P. Since there are many types of fixing structures and they are relatively conventional in this technical field, this utility model does not limit them.

[0032] See appendix Figure 3 - Appendix Figure 10 The drive mechanism 3 includes an inner coil 31 and an outer magnet 32. The inner coil 31 is fixedly installed in the support platform 10 and electrically connected to the control unit 5 as a stator. The outer magnet 32 ​​is fixedly installed on the fixed base 2 and the inner coil 31 is sleeved on it as a rotor. The fixed base 2 is provided with a rotating shaft 20, which is rotatably connected to the support platform 10. The end of the rotating shaft 20 extends into the support platform 10 and coaxially passes through the center of the inner coil 31.

[0033] Specifically, during use, the control unit 5 provides a constant current to the inner coil 31 to keep the outer magnet 32 ​​in its current position without rotating, thereby ensuring that the mounting base 2 remains stable in its current position. When the mounting base 2 and the shooting device P shift due to user hand tremors, the control unit 5, after receiving signal feedback from the positioning module 4, can provide a variable current to the inner coil 31 to drive the outer magnet 32 ​​to rotate clockwise or counterclockwise by a corresponding angle to compensate for the shift, ensuring that the mounting base 2 and the shooting device P return to their original angular positions. On the other hand, the design of the rotating shaft 20 being rotatably connected to the support platform 10 and coaxially passing through the center of the inner coil 31 not only realizes the rotatable connection between the mounting base 2 and the support platform 10, and allows the support platform 10 to provide support to the mounting base 2 through the rotating shaft 20, thereby improving the rotational stability of the mounting base 2, but also makes the overall structure more compact.

[0034] It should be noted that, in addition to the above-described structure, the drive mechanism 3 can adopt other components. For example, in one embodiment, the drive mechanism 3 can directly adopt a servo motor. The servo motor has an output shaft coaxially connected to the fixed base 2, and the servo motor is electrically connected to the control unit 5. After receiving the signal from the control unit 5, the servo motor can control the rotation of the fixed base 2 to perform dynamic compensation. In another embodiment, the drive mechanism 3 can also be composed of a motor, a transmission gear (not shown in the figure), and a gear ring (not shown in the figure). The gear ring is fixedly installed on the outer edge of the circumference of the fixed base 2 and meshes with the transmission gear. The motor is installed in the support platform 10 and is electrically connected to the control unit 5. The output shaft of the motor is coaxially fixed to the transmission gear so as to drive the fixed base 2 to rotate through the transmission gear. Since the types of drive mechanisms 3 are diverse and relatively conventional in this technical field, this utility model does not limit them.

[0035] See appendix Figure 3 - Appendix Figure 10 The positioning module 4 includes a first circuit board 41, a gyroscope chip (not shown in the figure) and an accelerometer (not shown in the figure). The first circuit board 41 is fixedly installed at the end of the rotating shaft 20 and electrically connected to the control unit 5. The gyroscope chip and the accelerometer are embedded in the first circuit board 41 to identify the angular offset of the shooting device P relative to the horizontal direction.

[0036] Specifically, the control unit 5 can power the gyroscope chip and accelerometer through the first circuit board 41. The gyroscope chip and accelerometer work together to identify the angular offset of the shooting device P in a timely manner, and feed back relevant signals to the control unit 5 through the first circuit board 41 so that the control unit 5 can control the drive mechanism 3 to run in a timely manner for dynamic compensation.

[0037] It should be noted that the positioning module 4 can also use other components with the function of recognizing shaking, such as an inertial measurement unit (IMU) chip. Since there are many types of related components and they can all achieve similar functions, no material is specified for them in this utility model.

[0038] See appendix Figure 1 - Appendix Figure 6 The control unit 5 includes a main control board 51, a battery 52, an anti-shake mode button 53, and a rotation mode button 54. The anti-shake mode button 53 and the rotation mode button 54 are both installed on the outer wall of the handheld part 1. The main control board 51 and the battery 52 are both installed inside the handheld part 1. The main control board 51 is electrically connected to the drive mechanism 3, the positioning module 4, the battery 52, the anti-shake mode button 53, and the rotation mode button 54.

[0039] Specifically, the battery 52 is used to power the main control board 51, which in turn powers the drive mechanism 3 and the positioning module 4, and is used to receive or transmit signals. The user can turn the anti-shake function on / off by pressing the anti-shake mode button 53, and turn the rotation function on / off by pressing the rotation mode button 54.

[0040] When the image stabilization function is enabled, the main control board 51 continuously receives feedback signals from the positioning module 4 and sends control signals to the drive mechanism 3 to drive the fixed plate to rotate and dynamically compensate the shooting device P. When the rotation function is enabled, the main control board 51 can directly send control signals to the drive mechanism 3 to drive the fixed plate to rotate at a specific speed, so that the captured content has a cinematic camera movement effect and improves the user experience.

[0041] It should be noted that the technology of powering the main control board 51 through the battery 52 and receiving and transmitting signals through the main control board 51 is existing technology. The control of the usage mode through the anti-shake mode button 53 and the rotation mode button 54 is determined by the preset program on the main control board 51, and the relevant control technology is very common in the field of electronics. Therefore, the specific circuit structure is not described in detail in this utility model. On the other hand, the battery 52 can be made removable, or a charging port 59 can be provided on the main control board 51 to charge the battery 52 through the handheld part 1 to the outside.

[0042] See appendix Figure 1 - Appendix Figure 6 The control unit 5 also includes a photo button 55, a lens switching button 56, and a focus wheel 57 mounted on the outer wall of the handheld part 1. The main control board 51 is also electrically connected to the shooting device P, the photo button 55, the lens switching button 56, and the focus wheel 57.

[0043] Specifically, during use, after the main control board 51 is electrically connected to the shooting device P, the sliding focus adjustment wheel 57 can start the camera of the shooting device P and focus or adjust the focal length. Pressing the shutter button 55 can control the camera to take pictures, and pressing the lens switching button 56 can control the shooting device P to switch between the front and rear cameras, which improves the convenience of operation.

[0044] It should be noted that the technology of receiving and processing feedback signals from the photo button 55, lens switching button 56 and focus wheel 57 through the main control board 51, and then sending corresponding control signals to the shooting device P to control the shooting device P is existing technology. The functions of the relevant buttons are determined by the preset program. Since the relevant control technology is relatively common in the field of electronics, its specific circuit structure will not be described in detail in this utility model.

[0045] See appendix Figure 6 - Appendix Figure 10The present invention also includes a supplementary lighting module 6, and a light-transmitting cover 13 opposite to the fixed base 2 is provided on the support platform 10; the supplementary lighting module 6 includes an LED bead 61 and a second circuit board 62, the second circuit board 62 is installed in the support platform 10 and electrically connected to the main control board 51, the LED bead 61 is embedded in the second circuit board 62 and corresponds to the light-transmitting cover 13, and the light emitted by the LED bead 61 can be emitted to the outside through the light-transmitting cover 13; the control unit 5 also includes a light button 58 installed on the outer wall of the handheld part 1, and the light button 58 is electrically connected to the main control board 51.

[0046] Specifically, the main control board 51 is used to supply power to the second circuit board 62 and send control signals, while the light button 58 is used to send signals to the main control board 51 to control the on / off of the lamp 61. During shooting, the lamp 61 can be turned on by pressing the light button 58, and the light emitted by the lamp 61 can be projected into the outside through the light-transmitting cover 13 to provide supplementary lighting, thereby further improving the shooting effect.

[0047] It should be noted that the technology of receiving and processing the feedback signal from the light button 58 through the main control board 51 and then sending the corresponding control signal to the light bead 61 to control the start and stop of the light bead 61 is existing technology. Therefore, its specific circuit structure will not be described in detail in this utility model.

[0048] The electrical connections mentioned above include wired electrical connections and wireless signal connections. Wired electrical connections refer to the transmission of electrical energy or signals through physical conductors (such as wires, cables, terminals, etc.); wireless signal connections refer to the transmission of signals through electromagnetic waves (such as Wi-Fi, Bluetooth, etc.), which do not require physical conductors but require circuit support. Since there are various ways to make electrical connections and they are quite common in the electronics field, manufacturers can selectively set them according to product requirements, and this utility model does not impose any restrictions on this.

[0049] See appendix Figure 4 - Appendix Figure 9 The present invention also includes a locking switch 7, which is mounted on the hand-held part 1 and used to lock or release the fixing base 2.

[0050] Specifically, when not in use, the locking switch 7 can be used to lock the fixed seat 2 to prevent the fixed seat 2 from rotating arbitrarily; when in use, the locking switch 7 is controlled to release the fixed seat 2 so that the drive mechanism 3 can smoothly drive the fixed seat 2 to rotate.

[0051] See appendix Figure 4 - Appendix Figure 9Since there are various types of locking switches 7, this utility model does not limit them. For ease of understanding, in this embodiment, the locking switch 7 includes a rotating base 71 and a swing rod 72. The handheld part 1 is provided with a movable opening 11 and a notch 12 that connect the inside and outside. The fixed base 2 is provided with a latch 23. The rotating base 71 is installed in the handheld part 1 and has a rotating groove 710. The swing rod 72 is rotatably connected to the rotating groove 710 and has rotational damping. The first end of the swing rod 72 is provided with a lever 721 that extends through the movable opening 11, and the tail end of the swing rod 72 is provided with a latch 722 corresponding to the notch 12. The lever 72 can be driven to swing by moving the lever at the movable opening 11, so that the latch 722 can enter and exit the notch 12 and engage or disengage from the latch 23.

[0052] Specifically, when not in use, the buckle 722 protrudes from the notch 12 and engages with the notch 23 to restrict the rotation of the fixed seat 2. When in use, the lever 72 is swung at the movable opening 11 to drive the buckle 722 to disengage from the notch 23 and enter the notch 12, thereby releasing the restriction on the fixed seat 2. When it is necessary to re-lock the fixed seat 2, the fixed seat 2 must first be rotated and reset by the drive mechanism 3 so that the notch 23 is realigned with the notch 12. Then, the lever 72 is swung at the movable opening 11 to drive the buckle 722 to protrude from the notch 12 and engage with the notch 23.

[0053] The rocker arm 72 is rotatably connected to the rotating groove 710 and has rotational damping. Therefore, the rocker arm 72 remains stationary when not subjected to external force, so as to prevent the buckle 722 from arbitrarily entering and exiting the notch 12 and interfering with the fixed seat 2. As for the method of setting rotational damping, a damper can be installed at the rotatable connection between the rocker arm 72 and the rotating groove 710, or the rotatable connection between the rocker arm 72 and the rotating groove 710 can be set as an interference fit. Since there are various related methods, this utility model does not limit this one.

[0054] It should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
