Description

Technical Field

[0001] This utility model relates to the field of shooting device technology, and in particular to an anti-loosening follow-up shooting gimbal and a shooting device with the gimbal. Background Technology

[0002] A gimbal is an intelligent shooting device that can automatically identify and track the subject, and through its built-in algorithms and sensors, ensure that the subject is always centered in the frame, thereby improving the stability and quality of the shot.

[0003] Current follow-up gimbals typically consist of a stator and mover directly connected to a motor shaft via screws or snap rings. The motor shaft directly bears the torque from the motor and the reaction force from external loads. Under high vibration and load conditions, the screws or snap rings can easily loosen or even fall off, causing shaky or stuttering footage and impacting the user experience. Furthermore, for ease of use, follow-up gimbals need to be lightweight, resulting in a very compact internal structure, which makes them difficult and costly to maintain. Additionally, the relatively thin motor shaft within the follow-up gimbal is prone to deformation under high loads and speeds, leading to decreased rotational accuracy and affecting shooting stability and clarity. Utility Model Content

[0004] To address the problems mentioned above in the background technology, the first objective of this utility model is to provide an anti-loosening follow-up gimbal, which has the advantages of stable structure, high rotation accuracy, more reliable fixing method, and is not easy to loosen.

[0005] The solution adopted by this utility model to solve its technical problem is:

[0006] A gimbal for preventing loosening during shooting includes an upper shell, a lower shell, a bottom cover, and a rotating assembly. The rotating assembly includes a first motor and a first bearing. The upper shell has a shooting connection part for connecting to an external shooting device at one end opposite to the lower shell. A first chamber is formed between the upper shell and the lower shell, and a second chamber is formed between the lower shell and the bottom cover. The first motor is fixed in the first chamber, and its output end extends out of the first chamber. The rotating assembly also includes a linkage structure, which includes a motor linkage part, a bearing mounting part, and a bracket connection part for connecting to an external bracket, all fixedly connected in sequence. The motor linkage part and the bearing mounting part are both axially fixed and circumferentially rotatable in the second chamber. The motor linkage part is linked to the output shaft of the first motor, and the first bearing is fixedly mounted on the bearing mounting part.

[0007] By adopting the above technical solution, the traditional structure that connects the motor shaft by screw locking or snap ring locking is replaced with a linkage structure. The first motor is linked to the motor linkage part. When the first motor rotates, the force concentrated on the output end of the first motor can be dispersed by the first bearing, so that the force on the output end of the first motor is more uniform, reducing the concentration of local stress at the output end of the first motor and preventing the first motor from separating from the lower housing.

[0008] Preferably, an anti-rotation gear ring is provided between the motor linkage part and the bearing mounting part. The upper housing is provided with a toggle opening groove, and a toggle push button is embedded in the toggle opening groove. The toggle push button includes a hand-operated part and an anti-rotation gear assembly part. The lower housing is provided with a notch for the anti-rotation gear assembly part to pass through. The hand-operated part can be moved up and down in the opening groove to control the anti-rotation gear assembly and the anti-rotation gear ring to lock or disengage from each other.

[0009] By adopting the above technical solution, the linkage connection between the first motor and the external bracket can be achieved by toggling the push button, or the linkage can be disengaged and achieved mechanically, resulting in a simple and reliable structure.

[0010] Preferably, the shooting connection part is axially fixed and circumferentially rotatable to the upper housing.

[0011] By adopting the above technical solution, the rotational freedom between the shooting equipment and the gimbal is increased. After the shooting equipment is installed on the gimbal, the center of gravity of the entire device can be adjusted through this structure, further improving the stability of the shooting equipment.

[0012] The second objective of this utility model is to provide an auxiliary device for shooting, which has the advantage of maintaining stable shooting results even after long-term use.

[0013] A shooting auxiliary device includes a selfie stick and / or a stabilizer, comprising a main handle, a clamping assembly for holding the shooting device, and a follow-up gimbal, wherein the follow-up gimbal is the aforementioned anti-loosening follow-up gimbal, the main handle is connected to a bracket connection part, and the clamping assembly is connected to the shooting connection part and can be flipped and rotated around the shooting connection part.

[0014] Preferably, the upper housing is rotatably connected to a secondary handle, which is attached to the outer wall of the main handle in the retracted state. The secondary handle contains a first battery for powering the first motor. The connection between the secondary handle and the upper housing is provided with a wiring structure to facilitate the concealment of wires.

[0015] Preferably, the clamping assembly includes a rotating arm and a clamping member. The rotating arm is rotatably connected to the shooting connection part, and the clamping member is rotatably connected to the end of the rotating arm away from the shooting connection part. The clamping member includes a clamping plate housing, a circuit board, a second motor, and a second battery. The second battery and the second motor are both electrically connected to the circuit board. The circuit board and the second battery are both disposed inside the clamping plate housing. The second motor is disposed inside the rotating arm and close to the end of the clamping member, and the output end of the second motor is connected to the clamping plate housing for driving the clamping member to rotate.

[0016] Preferably, the circuit board integrates an angle sensing component for detecting the rotation angle of the clamp, the clamp housing is provided with a display screen for displaying its rotation angle, the display screen is electrically connected to the angle sensing component, and the clamp housing is provided with a control key for controlling the rotation of the clamp, the control key is electrically connected to the circuit board.

[0017] Preferably, the rotating arm includes a first connecting arm and a second connecting arm that are rotatably connected. The first connecting arm is rotatably connected to the upper housing, and the end of the second connecting arm away from the first connecting arm is rotatably connected to the clamp. The second connecting arm has a receiving groove inside, and the second motor is disposed in the receiving groove.

[0018] Preferably, the second connecting arm is provided with a locking switch that locks with the second motor to prevent the second motor from controlling the rotation of the clamp, or unlocks the second motor to allow the second electrode to drive the clamp to rotate; the locking switch includes a push button, a main locking lever fixedly connected to the push button, and a secondary locking lever that locks or disengages from the main locking lever, and a return spring is provided between the second connecting arm and the secondary locking lever; a through groove is provided on the side of the second connecting arm, and the push button is slidably disposed in the through groove, so that the main locking lever and the secondary locking lever are locked or disengaged by the movement of the push button.

[0019] Preferably, the side wall of the secondary handle is provided with a slot, into which a remote control for controlling the rotation of the upper housing and the clamping assembly is inserted.

[0020] By adopting the above technical solution, the auxiliary device for shooting has the following advantages:

[0021] 1. The rotation between the pan-tilt head and the main handle is stable and reliable, and will not become loose after prolonged use;

[0022] 2. The entire shooting auxiliary device has multiple degrees of freedom, allowing the angle and center of gravity of the shooting equipment to be adjusted according to shooting needs;

[0023] 3. It allows for orderly wiring of electronic components inside the upper casing, preventing exposed wires and improving the product's overall quality.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Example 1

[0038] like Figures 1 to 3 As shown, an anti-loosening tracking gimbal includes an upper housing 11, a lower housing 12, a bottom cover 13, and a rotating assembly 2.

[0039] The upper housing 11 is provided with a shooting connection part 111 for connecting with an external shooting device at one end away from the lower housing 12. A first chamber 14 is formed between the upper housing 11 and the lower housing 12, and a second chamber 15 is formed between the lower housing 12 and the bottom cover 13.

[0040] The rotating assembly 2 includes a first motor 21 and a first bearing 22. The first motor 21 is fixed inside the first chamber 14, and the output end of the first motor 21 extends out of the first chamber 14.

[0041] The rotating assembly 2 also includes a linkage structure 23, which includes a motor linkage part 231, an anti-rotation gear ring 232, a bearing mounting part 233, and a bracket connecting part 234 for connecting with an external bracket, which are fixedly connected in sequence. (It should be noted that, in order to reduce production costs, the motor linkage part 231, the anti-rotation gear ring 232, the bearing mounting part 233, and the bracket connecting part 234 are preferably integrally formed.) The motor linkage part 231 and the bearing mounting part 233 are both axially fixed and circumferentially rotatable in the second chamber 15. The motor linkage part 231 is linked to the output shaft of the first motor 21. The first bearing 22 is fixedly mounted on the bearing mounting part 233. The bottom cover 13 is provided with a bottom cover hole. The bracket connecting part 234 is a rod-shaped structure that extends through the bottom cover hole and is linked to the external bracket.

[0042] It should be noted that, in order to make the transmission between the first motor 21 and the linkage structure 23 more stable, it is preferable that the motor linkage part 231 is provided with a channel in the middle, the output shaft of the first motor 21 is interference-fitted and / or fixedly connected in the channel, and a second bearing 24 is also provided between the motor linkage part 231 and the lower housing 12, the diameter of the first bearing 22 being larger than the diameter of the second bearing 24.

[0043] The upper housing 11 is provided with an actuating opening groove 112, and an actuating push button 3 is embedded in the actuating opening groove 112. The actuating push button 3 includes an integrally formed hand lever part 31 and an anti-rotation gear assembly part 32. The lower housing 12 is provided with a notch part 121 through which the anti-rotation gear assembly part 32 passes. The hand lever part 31 can be moved up and down in the opening groove to control the anti-rotation gear assembly to pass through the notch part 121, thereby locking with the anti-rotation gear ring 232. Alternatively, the anti-rotation gear assembly part 32 can move from the notch part 121 toward the upper housing 11 to disengage from the anti-rotation gear ring 232, thus realizing the driving of the first motor 21 and driving or disengaging it from the external support. This structure realizes the rotation locking or unlocking of the first motor 21 in a purely mechanical way, simply, conveniently, and at low cost, and is easy and reliable to operate.

[0044] The shooting connection part 111 is axially fixed and circumferentially rotatably connected to the upper housing 11. (It should be noted that the shooting connection part 111 and the upper housing 11 can be fixedly connected. In actual use, the shooting device connected to the shooting connection part 111 may be a mobile phone, camera or other terminal device. After the first motor 21 rotates to a certain angle, the center of gravity between the shooting device and the external support may change. Preferably, the two can rotate relative to each other, thereby increasing the rotational freedom between the shooting device and the gimbal. When the shooting device is installed on the gimbal, the center of gravity of the entire device can be adjusted through this structure to further improve the stability of the shooting device.)

[0045] Example 2

[0046] likeFigures 4 to 8 As shown, a shooting auxiliary device includes a selfie stick and / or a stabilizer, comprising a main handle 4 with a telescopic rod structure, a clamping assembly 5 for holding the shooting equipment, a follow-up gimbal, and a secondary handle 6. The main handle 4 is connected to the bracket connection part 234 (i.e., the main handle 4 constitutes the external bracket described in Embodiment 1), the follow-up gimbal is the anti-loosening follow-up gimbal described in Embodiment 1, and the clamping assembly 5 is connected to the shooting connection part 111 and can be flipped and rotated around the shooting connection part 111.

[0047] The secondary handle 6 is rotatably connected to the upper housing 11 of the tracking gimbal. In its retracted state, the secondary handle 6 is attached to the outer wall of the main handle 4 and parallel to the axial direction of the main handle 4. The secondary handle 6 includes a secondary handle housing 61, which houses a first battery (not shown in the diagram) for powering the first motor 21 and a control unit 62 for controlling the rotation of the first motor 21. A function button 63 is provided on the side of the secondary handle housing 61. The function button 63 is electrically connected to the control unit 62, and the motor can be started and stopped by controlling the function button 63.

[0048] The secondary handle housing 61 is provided with a wiring structure 64 for easy wiring (it should be noted that the wires here can be the wires of the first motor 21 or the wires of the main control circuit board located inside the upper housing 11, and the wiring structure 64 is located at the hinge connection between the secondary handle housing 61 and the upper housing 11. Preferably, the upper housing 11 and the secondary handle housing 61 together form the wiring structure 64). This structure can make the wiring of electronic components inside the upper housing 11 orderly, and the wires will not be exposed, thus improving the quality of the product.

[0049] The two are connected to ensure that no wires are exposed, achieving concealed wiring and making the pan-tilt head more aesthetically pleasing.

[0050] The clamping assembly 5 includes a rotating arm 50 and a clamp 51. The rotating arm 50 includes a first connecting arm 501 and a second connecting arm 502 that are rotatably connected. (It should be noted that the rotating arm 50 can be integrally formed. In order to increase the rotation angle when the clamping assembly 5 clamps the shooting device, it is preferable that the rotating arm 50 is set to be a first connecting arm 501 and a second connecting arm 502 that are rotatably connected.)

[0051] The first connecting arm 501 is rotatably connected to the upper housing 11 (preferably rotatably connected to the shooting connection part 111), and the end of the second connecting arm 502 away from the first connecting arm 501 is rotatably connected to the clamp 51. The second connecting arm 502 is provided with a receiving groove 5021 inside.

[0052] The clamp 51 includes a clamping plate housing 511, a circuit board 512, a second motor (not shown in the figure), and a second battery 514. The second battery 514 and the second motor are both electrically connected to the circuit board 512. The circuit board 512 and the second battery 514 are both disposed inside the clamping plate housing 511. The second motor is disposed inside the second connecting arm 502 and located at one end near the clamp 51 and disposed in the receiving groove 5021. The output end of the second motor is connected to the clamping plate housing 511 for driving the clamp 51 to rotate as a whole. The circuit board 512 integrates an angle sensing component for detecting the overall rotation angle of the clamp 51. The clamping plate housing 511 is provided with a display screen for displaying its rotation angle. The display screen is electrically connected to the angle sensing component. The clamping plate housing 511 is provided with a control key for controlling the rotation of the clamp 51. The control key is electrically connected to the circuit board 512.

[0053] The second connecting arm 502 is provided with a locking switch that locks with the second motor to prevent the second motor from controlling the clamp 51 to rotate, or unlocks the second motor to allow the second electrode to drive the clamp 51 to rotate (it should be noted that the locking switch can lock or unlock the entire second motor, or it can lock or unlock the rotor of the second motor).

[0054] The locking switch includes a push button 71, a main locking lever 72 fixedly connected to the push button 71, and a secondary locking lever 73 locked or disengaged from the main locking lever 72. A return spring 74 is provided between the second connecting arm 502 and the secondary locking lever 73. A through groove is provided on the side of the second connecting arm 502, and the push button 71 is slidably disposed in the through groove. The locking or disengagement of the main locking lever 72 and the secondary locking lever 73 is achieved by the actuation of the push button 71. Specifically, the main locking lever 72 is provided with a protrusion, and the secondary locking lever 73 is provided with a wedge-shaped groove. By the actuation of the push button 71, the protrusion is inserted into or disengaged from the wedge-shaped groove (that is, when the protrusion is inserted into the wedge-shaped groove, the return spring 74 is compressed; when the push button 71 is actuated in the opposite direction, the return spring 74 releases its stored energy, and the protrusion disengages from the wedge-shaped groove), so that the main locking lever 72 and the secondary locking lever 73 are locked or disengaged.

[0055] The side wall of the secondary handle 6 is provided with a slot, into which a remote control 8 for controlling the rotation of the upper housing 11 and the clamping assembly 5 can be detachably inserted. The remote control 8 can also control the pan-tilt head for shooting.

[0056] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
