Description

Technical Field

[0001] The present invention relates to the technical field of photographing equipment, and in particular to a three-axis handheld stabilizer. Background Art

[0002] In the prior art, the three-axis stabilizer includes three rotating axes, namely, X-axis, Y-axis and Z-axis. In the structural design of the three-axis stabilizer, the stator of the heading motor is connected to the handle, the rotor of the heading motor and the stator of the roll motor are connected through a connecting arm, and the rotor of the roll motor is connected to the stator of the pitch motor through another connecting arm. The rotor of the pitch motor is connected to a fixture, and three control chips are correspondingly arranged at the stators of the three motors. At the same time, an attitude plate is also arranged at the fixture to detect the attitude information of the carrier loaded on the fixture. However, the inventor found in the research on the three-axis stabilizer that the wiring of the power harnesses between the various rotating axes is complicated and the harnesses are intertwined with each other, making the wiring operation difficult. Therefore, there is still much room for improvement in the structural design of the stabilizer. Summary of the invention

[0003] The present invention provides a three-axis handheld stabilizer to solve the technical problem that the structural design of the existing three-axis stabilizer leads to complicated threading and great difficulty in operation. The present invention can optimize the structure of the three-axis stabilizer and reduce the difficulty of threading.

[0004] In order to solve the above technical problems, an embodiment of the present invention provides a three-axis handheld stabilizer, including a handle, a fixture, a main control chip, a posture data acquisition module, and an X-direction rotation axis, a Y-direction rotation axis, and a Z-direction rotation axis installed between the handle and the fixture;

[0005] The X-direction rotation axis includes a panning motor and a first control board arranged on the stator of the panning motor, the Y-direction rotation axis includes a roll motor and a second control board arranged on the stator of the roll motor, the Z-direction rotation axis includes a pitch motor connected to the fixture and a third control board arranged between the stator of the pitch motor and the fixture, the rotor of the panning motor is connected to the handle, the stator of the panning motor is connected to the rotor of the roll motor through a first connecting arm, and the stator of the roll motor is connected to the rotor of the pitch motor through a second connecting arm;

[0006] The main control chip is arranged on the second control board, and the second control board is connected to the first control board through a first wiring harness, the second control board is connected to the third control board through the second wiring harness, and the posture data acquisition module is arranged on the third control board and connected to the second wiring harness.

[0007] As a preferred solution, the first wiring harness is embedded in the wiring cavity of the first connecting arm, and the second wiring harness is embedded in the wiring cavity of the second connecting arm.

[0008] As a preferred solution, the second wire harness passes through the hollow shaft of the roll motor and is connected to the second control board.

[0009] As a preferred solution, the second wire harness passes through the hollow shaft of the pitch motor and is connected to the third control board.

[0010] As a preferred solution, the clamp is connected to the stator of the pitch motor, and the third control board is located in a receiving cavity between the stator of the pitch motor and the clamp.

[0011] As a preferred solution, a button control panel is provided on the handle, and the button control panel is connected to the first control panel.

[0012] Compared with the prior art, the beneficial effect of the embodiment of the present invention lies in that, by directly arranging the main control chip on the second control board, the first control board, the second control board, and the third control board share one main control chip, and the structural design of the rotor of the heading motor connected to the handle and the stator connected to the roll motor can make the first control board close to the main control chip, thereby effectively shortening the length of the first wiring harness; in the prior art, when the main control chip is arranged on the first control board, since the number of wires in the first wiring harness is large and the stator of the heading motor and the control board are designed close to the handle, this will cause the first wiring harness to be difficult to pass through the heading motor and be connected to its stator. In this way, compared with the prior art solution that the first wiring harness must pass through the heading motor to connect to the control board, the present invention not only shortens the length of the first wiring harness, but also saves space for storing and accommodating the first wiring harness, which is beneficial to saving wires and optimizing the equipment structure.

[0013] The rotor of the pitch motor is connected to the roll motor through the second connecting arm, and the stator is connected to the fixture, so that the third control board and the attitude data acquisition module can share a circuit control. By swapping the positions of the stator and rotor of the pitch motor, the circuit wiring is simplified, the mutual entanglement of the lines can be avoided, and the wiring harness accommodation space can be saved. Among them, the third control board is located between the stator of the pitch motor and the fixture, which realizes the placement of the wiring harness and the centralized setting of the circuit board, thereby optimizing the structural design of the Z-direction rotation axis connecting the fixture.

[0014] In addition, compared with the existing solution that designs the main control chip on the second control board but makes it difficult for the first wiring harness to bypass the heading motor, the main control chip is arranged on the second control board, located in the middle position of the stabilizer, so that it is divergently connected to each control board, which will help simplify the threading operation.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 , an embodiment of the present invention provides a three-axis handheld stabilizer, including a handle 1, a fixture 2, a main control chip, a posture data acquisition module, and an X-direction rotation axis, a Y-direction rotation axis, and a Z-direction rotation axis installed between the handle 1 and the fixture 2;

[0021] The X-direction rotation axis includes a heading motor and a first control board 5 provided on the stator of the heading motor, the Y-direction rotation axis includes a roll motor and a second control board 6 provided on the stator of the roll motor, the Z-direction rotation axis includes a pitch motor connected to the fixture 2 and a third control board 7 provided between the stator of the pitch motor and the fixture 2, the rotor of the heading motor is connected to the handle 1, the stator of the heading motor is connected to the rotor of the roll motor through a first connecting arm 3, and the stator of the roll motor is connected to the rotor of the pitch motor through a second connecting arm 4;

[0022] The main control chip is arranged on the second control board 6, and the second control board 6 is connected to the first control board 5 through the first wire harness A, the second control board 6 is connected to the third control board 7 through the second wire harness B, and the posture data acquisition module is arranged on the third control board 7 and connected to the second wire harness B.

[0023] In this embodiment, the main control chip is directly arranged on the second control board 6, the first control board 5, the second control board 6, and the third control board 7 share one main control chip, and the rotor of the heading motor is connected to the handle 1, and the stator is connected to the roll motor. The structural design enables the first control board 5 to be close to the main control chip, thereby shortening the length of the first wiring harness A. In the prior art, when the main control chip is arranged on the first control board 5, since the number of wires in the first wiring harness is large and the stator of the heading motor and the control board are designed close to the handle, it will cause the first wiring harness to be difficult to pass through the heading motor and be connected to its stator. Compared with the prior art solution in which the first wiring harness A must pass through the heading motor to connect to the control board, the present invention not only shortens the length of the first wiring harness A, but also saves space for storing and accommodating the first wiring harness A, which is beneficial to saving wires and optimizing the equipment structure.

[0024] Among them, the rotor of the pitch motor is connected to the roll motor through the second connecting arm 4, and the stator is connected to the clamp 2, so that the third control board 7 and the attitude data acquisition module can share a circuit control. By swapping the positions of the stator and rotor of the pitch motor, the circuit wiring is simplified, the mutual entanglement of the lines can be avoided, and the wiring harness accommodation space can be saved; at the same time, the third control board 7 is located between the stator of the pitch motor and the clamp 2, which realizes the placement of the wiring harness and the centralized setting of the circuit board, thereby optimizing the structural design of the Z-direction rotation axis connecting the clamp 2.

[0025] In addition, compared with the existing solution in which the main control chip is designed on the second control board 6 but makes it difficult for the first wiring harness A to bypass the heading motor, the main control chip is arranged on the second control board 6, located in the middle position of the stabilizer, so that it is divergently connected to each control board, which will help to simplify the threading operation.

[0026] In one embodiment of the present invention, the first wiring harness A is embedded in the wiring cavity of the first connecting arm 3, and the second wiring harness B is embedded in the wiring cavity of the second connecting arm 4, so that the first wiring harness A can be hidden in the first connecting arm 3, and the second wiring harness B can be hidden in the second connecting arm 4, which can effectively reduce the volume of the overall structure and enhance the aesthetics of the stabilizer. In addition, the first wiring harness A and the second wiring harness B are both placed in the wiring cavity, which is convenient for assembly, maintenance and replacement. It should be noted that the first wiring harness A includes a control signal line and a power line, and the second wiring harness B also includes a control signal line and a power line.

[0027] In one embodiment of the present invention, the second wire harness B passes through the hollow shaft of the roll motor and is connected to the second control board 6, and the second wire harness B passes through the hollow shaft of the pitch motor and is connected to the third control board 7. In this embodiment, the roll motor and the pitch motor are both hollow shaft motors, and both have inner holes for routing, light transmission, or other media such as air. When threading, the second wire harness B is passed through the hollow shaft of the roll motor and the hollow shaft of the pitch motor, which can hide the wire harness and avoid entanglement of the wire harness, thereby greatly optimizing the threading design of the wire harness inside the stabilizer.

[0028] In one embodiment of the present invention, the fixture 2 is connected to the stator of the pitch motor, and the third control board 7 is located in the accommodating cavity between the stator of the pitch motor and the fixture 2 .

[0029] In this embodiment, since the attitude data acquisition module is arranged on the third control board 7 and is used to detect the attitude information of the carrier loaded on the fixture 2, the third control board 7 is arranged in the accommodating cavity between the stator of the heading motor and the fixture 2, so that the third control board 7 can share a circuit control with the attitude data acquisition module. Compared with the existing scheme, the present invention effectively reduces the difficulty of the internal circuit board layout design of the stabilizer, and is also conducive to reducing the difficulty of threading.

[0030] In one embodiment of the present invention, a button control panel 8 is provided on the handle 1, and the button control panel 8 is connected to the first control panel 5 by wire. When the user holds the three-axis handheld stabilizer, the stabilizer can be wirelessly controlled by touching the buttons on the button control panel 8.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
