[0032] In this embodiment, the connecting bracket adopts a Y-shaped bracket. In actual use, it can be adjusted as needed. It can be a structure like a handheld camera stabilizer in the prior art, a tripod, etc., as long as it can achieve the corresponding function.

Figure 5 The figure shows the connection diagram of the orthogonal three-axis camera stabilizer and the remote control handle.

[0038] like Figure 4 As shown, a connecting clamp fixing pin 302 is provided at the top center of the remote control handle 3.

[0045] Furthermore, a socket fixing nut 308 is provided on the remote control handle 3, which plays a fixing role when the remote control handle 3 is connected to the tripod and the rocker arm.

[0046] The roll axis of the orthogonal three-axis camera stabilizer of the present invention adopts a hollow shaft motor 2, and a photographic device or a photographic device bracket is installed in the space formed inside the hollow shaft 202 of the hollow shaft motor 2, so that the photographic device or the photographic device bracket can rotate 360 ​​degrees around the Y axis; the outer ring of the hollow shaft motor 2 is connected to the pitch axis motor 102 and the pitch bracket 103, so that the photographic device or the photographic device bracket can rotate 360 ​​degrees around the X axis; the pitch axis motor 102 and the pitch bracket 103 are respectively connected to the pan axis motor 104 through the connecting arm 101, so that the photographic device or the photographic device bracket can rotate 360 ​​degrees around the Z axis. The three motor shafts are arranged orthogonally and do not need to cooperate with each other. Each motor shaft has its own function and can rotate 360 ​​degrees, maximizing the angle adjustment. In addition, when adjusting the posture of the orthogonal three-axis camera stabilizer, the lens or display screen of the photographic device will not be blocked, and there will be no collision of components. The device is easy to store and carry.

[0047] like Figure 6 and Figure 7 The figure shows the connection diagram of the orthogonal three-axis camera stabilizer and the remote control handle of another structure, wherein the remote control handle and Figure 4 The remote control handles have different appearances and structures but the functions are the same.

[0048] The orthogonal three-axis stabilizer can be integrated with the shooting equipment, such as Figure 8 As shown, the shooting lens 5 is directly embedded in the space formed inside the hollow shaft 202; the bracket 4 can also be installed in the space formed inside the hollow shaft 202, as shown in FIG. Figure 9 As shown, a mobile phone 6 is mounted on the bracket 4, as shown in FIG. Figure 10 As shown, a camera 7 is mounted on the bracket, a mobile phone 6 or camera 7 is fixed using the bracket 4, and the action of the three motors is controlled by the function buttons on the remote control handle to control the position of the shooting lens 5 or the bracket 4, thereby adjusting the shooting angle.

[0049] The orthogonal three-axis stabilizer utilizes a hollow-shaft motor. This involves enlarging the diameter of the motor's stator, rotor, and bearings, creating a hollow motor shaft. The hollow shaft creates a space within which the camera or camera mount can be installed. Mounted inside the hollow motor, the camera or camera mount is protected from the motor's front and rear impacts, providing a superior user experience. The hollow motor provides more space for additional windings and magnets, improving roll stabilization accuracy. If the camera or camera mount exhibits abnormal posture deviation, the orthogonal three-axis stabilizer's circuitry and motor provide real-time correction, stabilizing the camera and improving filming quality. The orthogonal three-axis stabilizer can be manufactured integrally with the camera, or various camera mounts can be installed within the hollow shaft to accommodate mobile phones, cameras, and other large, medium, and small cameras. For larger cameras, the motor size and power can be increased, and the connecting arm's shape can be adjusted to prevent obstruction. The remote control handle can control the working mode and posture adjustment of the orthogonal three-axis stabilizer, and can also operate some functions supported by the shooting equipment. It is divided into one-handed and two-handed types. The two-handed type is suitable for use with large and medium-sized shooting equipment.

[0050] The specific working process of this utility model is:

[0051] A shooting lens is embedded in the space formed inside the hollow shaft, or a shooting equipment bracket is installed. The shooting equipment bracket is used to fix a mobile phone or camera. The orthogonal three-axis camera stabilizer is connected to the remote control handle, and the function buttons on the remote control handle are used to control the actions of the three motors. That is, the hollow shaft motor is used to adjust and stabilize the roll direction of the shooting equipment or the shooting equipment bracket, so that the shooting equipment or the shooting equipment bracket can rotate 360 ​​degrees around the Y axis to maximize the roll angle adjustment. The pitch axis motor 102 cooperates with the pitch bracket 103 to adjust and stabilize the pitch angle of the shooting equipment or the shooting equipment bracket, so that the shooting equipment or the shooting equipment bracket can rotate 360 ​​degrees around the X axis to maximize the pitch angle adjustment. The pan axis motor 104 is used to adjust and stabilize the direction of the shooting equipment or the shooting equipment bracket, so that the shooting equipment or the shooting equipment bracket can rotate 360 ​​degrees around the Z axis to maximize the pan angle adjustment.

[0052] The orthogonal three-axis photo stabilizer is directly connected to the tripod to become an omnidirectional remote control gimbal. The orthogonal three-axis photo stabilizer can be connected to a selfie stick or a rocker arm to extend to a distance for remote lighting and shooting.

[0053] The remote control handle 3 can work independently through the remote control transmitting circuit and control circuit set inside, becoming a handle-shaped remote control. The handle-shaped remote control can simultaneously remotely control the orthogonal three-axis photo stabilizer and supported shooting equipment; the connecting card head fixing pin 302 of the handle-shaped remote control can also be connected to an adaptive wireless touch display screen and mobile phone holder, making it convenient to monitor the shooting images of the shooting equipment in various postures from a long distance.
